sef canada is working with artisanal miners in ecuador to eliminate mercury in gold processing while developing local economies. sef canada’s managing director suzette mcfaul discusses the project’s community-driven approach to developing more sustainable practices in artisanal gold mining.

on 16 august, the minamata convention on mercury entered into force, marking the culmination of a years-long effort to come up with an international response to the shared threat of mercury exposure.
while mercury has been used in industrial processes for hundreds of years, its extreme toxicity poses massive public health risks. mercury poisoning can cause irreparable brain damage and organ failure, and low-level exposure is a significant cause of premature deaths.
the minamata convention, named after the japanese city that has been living for decades with the consequences of a mass mercury poisoning, brings with it tighter controls for the handling of mercury in industry, as well as provisions for what it calls the “phase-out and phase-down of mercury use in products and processes”.
it also means renewed scrutiny on the use of mercury in artisanal and small-scale mining (asm) in many countries, and artisanal gold mining in particular. mercury is used extensively in asm operations, and often in highly unsafe domestic conditions, to process ore and recover gold.
but for small-scale miners working with simple tools and lacking the deep pockets, greater pressure to stop using mercury hasn’t changed the economic fundamentals of their trade. technical limitations mean that recovery rates are low and the grey market buyers of their gold, often jewellers, offering far below spot value. “and that’s if they don’t get mugged on the way in a cash-based society,” says mcfaul.
after being invited to southern ecuador’s el oro province in 2014 to see how sef’s economic development model might help artisanal mining communities, mcfaul established clean gold community solutions (clean gold) to take a more holistic approach to improving asm standards in the region.
the company has partnered with artisanal miners, along with a technical ‘dream team’ led by the university of british columbia, to make the transition away from mercury processing, while also taking on the upgrade of a local gold processing plant to refine the miners’ products and instilling business development skills to empower the miners as business owners.
the plant, which mcfaul says should be up and running “around next week”, will switch out mercury for cyanide in the recovery process, as the latter breaks down much more quickly if released. but the partnership, mcfaul stresses, is about more than just replacing a harmful industrial element; it’s about building new, sustainable systems centred around the plant.
in turn, transparency around processing methods and environmental performance facilitates access to markets that will offer close to spot prices for the miners’ gold, rather than the 40-60% of spot price that mcfaul says they get from grey market buyers.
at the heart of clean gold’s model is prioritising the economic and social health of the whole community that surrounds asm operations. this starts with only partnering with miners who have invited the company to do so, and developing the local economy is part of the deal.
“the community has to buy in and the community has to win,” says mcfaul. “there’s a community foundation that comes out of every clean gold project. “the community has to agree, and the miners agree, that part of that community foundation will go into an sef model to help all the other people in the community.
the approach aims to be the polar opposite of the exploitative, opaque relationships that can characterise mining communities’ interactions with large-scale mining companies. putting the reins in the hands of the community helps create a virtuous cycle that is key to the wider economic development plan, even if a hands-off approach presents its own challenges.
clean gold is keen to expand its methods to asm communities around the world. plans are already in place to set up another project in ecuador next year, and mcfaul is hoping that the current plant upgrade and community development scheme will be a strong showcase to help sell the concept to prospective future investors.
if the money can be found, there is apparently no shortage of demand for the clean gold model. the company has already visited guyana, and mcfaul says invitations have been extended from neighbouring colombia, as well as kenya and mali.
certainly there are challenges still to come. if the model is to be a true success on its own terms, it will be vital that miners and local families are as happy with the profit-sharing arrangement as the investors. but if the project in el oro province can make its environmental, ethical and business case, it could set a progressive template for cleaning up artisanal gold mining while also encouraging sustainable growth in communities that often live well below the poverty line.

optimize well placement. improve production.
operating directly behind the drill bit, the ipzig at-bit inclination and gamma ray tool provides real-time measurements that reduce directional drilling risk in critical hole sections. the early indication of changes in lithology, delivered by the gamma ray log, helps to accurately land horizontal wells.
designed to operate as two separate subs, a lower sub, located directly above the drill bit, acquires data and transmits data to the upper sub, located above the drilling mud motor. the upper sub provides communication to measurement/logging-while-drilling systems.
the ipzig can accommodate flexible bottomhole assembly (bha) designs, and is compatible with any drilling mud motor. ipzig provides the closest to the bit sensor offsets available in the industry and is the only tool to provide both gamma and inclination at the bit. these measurements are used to help determine well path placement and determine position in real-time while drilling.
the ipzig sub is an accurate, cost effective geosteering solution whether drilling for optimum reservoir drainage, setting casing, or just to determine position real-time while drilling.

perhaps you make a good point there bizaro. my past experience in following ffh's investments has made me gun shy of doing that. these guys are in a different game and this could be a sound idea.
1) lundin is a much larger company (by market cap) than yamana. they have more financial resources to fund the $250 million expansion projects at chapada (throughout increase and sucupira pit pushback).
2) lundin is a copper-focused company. chapada is primarily a copper mine with significant gold credits. lundin spends a lot of money aggressively exploring for copper at its properties. the yamana copper reserves and resource growth will likely ramp up under lundin's exploration team.
this is more or less the entire argument, if you ask me. just can take a looooong time to play out given how long cycles last and how long it takes to get a mine from idea to production.
bhp makes a strategic investment in midland, way above current market price. c$5.9 million raised at 1.70 a share.
bhp gets right of first offer on mythril. if the drilling hits bhp wants the project because it is potentially a very large copper deposit (based upon the ip surveys).
lundin conference call emphasizes that they have no capital constraints compared to yamana. they plan to bring copper production forward in an aggressive manner. i expect the gold-only suruca deposit to be shelved, while chapada expansion timeline will be accelerated. yamana had been slowplaying the major expansion spending to try to keep a cash flow positive profile for a few years.
i can imagine the conservatives putting political pressure on the utilities to delay the coal power plant conversions a few years to save thousands of coal mine or coal power plant related jobs. phaseout is inevitable but the exact timing is still up in the air, especially for the genesee plants.
wolfden resources cutting timber for forest management has been kicking out revenue to altius. altius gets 20% of the sales receipts from timber sales. altius received c$92,232 in timber revenue in 2018, and has received c$66,299 so far in 2019. see wolfden’s most recent md&a. i believe these sales receipts become part of altius’s project generation revenue.
these regular sales are separate from what will eventually be a total sale of the mt. pickett timber rights (for at least us$5 million).
because the total sale of timber rights didn’t happen by november 2018 altius can now, at any time, demand the return of what it paid for the mt. pickett royalty, c$7.663 million, in cash or shares of wolfden.
wolfden was a speculative royalty deal but altius built some excellent protections into the deal.
strong q1 performance and raised guidance. potash is performing very well.
altius should be in striking range for c$90 million total revenue in 2019 (royalty and project generation revenue). this preliminary q1 royalty number doesn’t include ~c$300k from voisey’s bay and pg revenue (timber sales etc). lif must keep paying out and chapada should have a big second half of the year with the improved recovery circuits installed this quarter. maybe a couple hundred thousand extra revenue from excelsior in q4.
90 million would be quite a reach. i will stick with 80 million for the year. lundin buying chapada, ucp win, highest quarter royalty revenue record, raised guidance and altius barely moves. i think capitalcities comment about the market not caring sums it up nicely.

1) the development of screw conveyor can be divided into two process, shaft type auger conveyor and shaftless type auger conveyor.
a. shaft type auger conveyor consists of screw, u type trough, cover plate, inlet, outlet and drive device, which has three types of installation mode, horizontal, inclined and vertical mounting.
b. shaftless type auger conveyor uses shaftless spiral blade to replace screw, and u type trough is equipped with replaceable lining. the structure of shaftless type auger conveyor is simple, the material is fed into inlet and moving towards outlet by spiral blades. the whole conveying process is made in a fully closed trough.
2) gx type auger conveyor is appeared in early phase of screw conveyor and is the earliest universal equipment in china. it mainly transports powdery, granular and small lumpy material, and is not suitable to convey perishable, viscous, easily caked and large chunks of material, because these material are easy to bond on the spiral blades, or block at the position of hanger bearing, which will cause inconvenience to the transportation process. the advantages of gx screw conveyor are energy-saving, low consumption, dust prevention, good sealing, low noise, well-adapted, easy operation and maintenance, flexible arrangement of the positions of inlet and outlet. the disadvantages are huge power consumption, quick wearing of conveyor parts, serious material crushing in the transportation process.
3) ls type auger conveyor is new generation of screw conveyor, which is designed and improved on the basis of gx type auger conveyor. the advantages are novel structure, reliable performance, advanced technology, wide range of application, significant energy saving and consumption reducing.
1) large capacity, high speed and long service life.
2) low energy consumption. most of the energy for screw conveyor is spent on abrasion.
3) intelligent development. the future auger conveyor should be closely connected with computer. it will be suitable for program control and intelligent operation. the material handling, equipment installation and maintenance should be intelligent management.
4) screw conveyor can be curved transportation.
5) combined, compound and large-scale transportation mode. screw conveyors are co-used with various kinds of continuous conveying equipments to finish complicated material handling. large-scale transportation includes large capacity, the length of single conveyor and high angle conveying, etc.
6) to expand the scope of application. at present, the usage range of auger conveyor is restricted. the scope of application should be expanded, to design the auger conveyors that can be operated in corrosive, radioactive, flammable material environment in the condition of high and low temperatures, as well as the conveyors which can transport molten, explosive, easily coking and viscous materials.
7) to design auger conveyor using environmental awareness, and reduce the pollution to achieve the goal of green design.

the 2d perovskite solar cell exceeds expectations for solar cell efficiency.
a 2d, layered form of the crystalline material perovskite has become the focus of much excitement in the solar cell research field at the los alamos national laboratory (usa).
the research team intends to lower the integral costs of pv-modules, by developing a worldwide unique aaa-class in-line steady state solar simulator (ilss) prototype for the pv-industry that is validated on criteria for test speed (5 modules/minute), test accuracy, heat development, maintenance and lamp replacement costs.
why do we need an automated test-measurement system for solar modules? pv-module manufacturers require automated inline testing equipment that provide accurate information about pv-module performance with industrial robustness and low testing cost per module.

the need for rapid and smooth decision-making has grown in all sectors – everyone needs data that has been analysed in a reliable and intelligent way, and they need it in real time, not tomorrow or next week.
predictive analytics and automatic optimisation have now allowed many, but far from all, to improve the efficiency of various business processes. a fast-growing area of application is now financial management and budgeting.
analysed and processed data/information provides managers with a deep insight into their company’s actual situation and also a glimpse of the future and proposals for measures. within follow-up and planning of business, advanced data analysis makes it possible to go from traditional models to more automated analyses that utilise far more data of different types than has been the case up to now.
new types of analytics tools mean it is now possible to collect and utilise even larger and more diverse data masses. advanced, predictive analytics finds patterns and relationships in places where, until now, it has been almost impossible to find them. these patterns allow us to predict the future in a surprisingly reliable way.
when finance professionals have access to reliable information that is based on both historical data and future scenarios, it means that they no longer need to spend time on traditional, and often very time-consuming, routine tasks and they can instead focus on more important matters: analysing and planning various business options.
the old, goal-based budgeting routines can therefore be consigned to history. the traditional type of budgeting can be automated. self-learning algorithms can generate “routine budgets”, i.e. predict the future based on existing historic data. this means predictive analytics is the number one tool in financial management. it offers considerable opportunities for more efficient and improved budgeting, especially with growing data quantities.
after budgeting has been automated, the next phase is to produce possible scenarios. for example, how would strategy-based reallocation of resources to a certain area affect the company’s outlook? or would it be possible to generate added value for the scenarios and subsequently for decision-making by collecting real-time production data for the predictive model? analytics methods can be used to examine and compare the relationships between financial and non-financial data. this can be used to model cause and effect relationships and to support strategy-based budgeting and decision-making. and this is the point where the finance professionals can finally take over.
predictive analytics produces the most successful budgets in situations where business operations continue unchanged.
predictive analytics models can be used to produce budget suggestions based on different scenarios and to quickly produce predictions of the way in which different decisions influence the company’s result.
automatic optimization can help find the budget scenario that best supports the company’s strategy.

zero emissions class 8 heavy-duty class 8 18-wheelers are a reality today. the innovative kansas city company orange ev is the first and only company to make all-electric big rigs commercially available. their electric terminal trucks are operating throughout the country.
however, over-the-road electric class 8 trucks are another story – to date only prototype and demonstration zero emissions class 8 trucks capable of operating on public highways have been produced.
as we reported late last year in nikola announces “the end of diesel engines”… electric class 8 heavy-duty trucks using power generated by hydrogen fuel cells will be truly zero-emissions if the hydrogen is generated by solar energy. nikola motors has an ambitious and innovative plan to do that on the national level by 2020, with solar-powered refueling stations on major truck routes throughout the country. their solution has a number of other innovative features, and they have produced a very impressive demonstration vehicle.
by the end of 2016, nikola reported that they had received over 7,000 preorders worth over $2 billion.
mercedes-benz is also moving into this market, and has promised to deliver prototypes of its all-electric mid-range (124 miles) urban etruck this year, and produce it commercially in 2020.
last week, two more firms joined the zero emissions trucking race – tesla announced that they have an electric semi under production, and toyota developed a prototype hydrogen-electric drayage truck for use at the port of los angeles.

the properties of soft cohesive soils can be improved by mixing of a variety of chemical additives. the addition of lime, fly ash and cement in different combinations can significantly improve the shear strength and compression properties of such soils. other additives can be used to fix pollutants in place to prevent leaching or to reduce soil permeability. deep soil mixing (dsm) is achieved using either a wet or a dry process where metered quantities of additives are injected into the soil through the hollow stem of a rotary drill string fitted to a drilling rig.
the method helps to achieve significant improvement of mechanical and physical properties of the existing soil, which after mixing with cement or compound binders becomes the so-called soil-mix (or soil-cement). the stabilized soil material that is produced has a higher strength, lower permeability and lower compressibility than the native soil.
there are two different mixing methods of deep soil mixing. the existing soil which has to be improved can be mixed mechanically, either with a slurry including binder (wet dsm) or with a dry binder (dry dsm). jetting of slurry can be also used to boost the mechanical mixing.
the wet method is more appropriate in soft clays, silts and fine-grained sands with lower water content and in stratified ground conditions including interbedded soft and stiff or dense soil layers. the dry method is more suitable for soft soils with very high moisture content, and hence appropriate for mixing with dry binders.
this method consists of a special mixing tool which is inserted into the soil on site. this mixing tool comprises of a drilling rod, transverse beams and a drill end with a head. the drilling does not cause any vibrations, and is accommodated by cement slurry outflow from nozzles intentionally placed at the end of the soil auger. when the design depth is reached, the construction phase of deep soil mixing (dsm) columns is started.
mass wet soil mixing is carried out with a horizontal axis rotary mixing tool at the end of a track hoe arm. the binder slurry is injected through a feed pipe which is attached to the arm.
this technique creates individual soilcrete columns, rows of overlapping columns, all of which have a specific design strength and stiffness. wet soil mixing is suitable to any soil types which includes even organic soil. with this method, the treatment of soil is possible to depths up to 100 feet.
dry soil mixing is a ground improvement technique that mechanically mixes the soil with dry cementitious binder to create soilcrete so as to improve the weak soils such as soft, high moisture clays, peats. a high speed drill moves into the ground with a drill rod which has radial mixing paddles near the bottom so as to construct the columns. during the penetration of the tool into the ground, it shears the soils to prepare them for mixing. as and when the tool the specified design depth, the binder is injected through the drill steel where it is assorted with the soil as the tool is taken out.
mass dry soil mixing is carried out with a horizontal axis rotating mixing tool positioned on the end of a track hoe arm. the binder is injected to the soil mixing tool through a feed pipe, which is attached to the track hoe arm. with dry soil mixing, the treatment for the soil is possible to depths up to 60 feet. obstructions are sometimes pre-drilled ahead of the soil mixing process.
when there is need for ground improvement work or site remediation and the soil is very weak or contaminated soil with high water content such as deposits of dredged sediments or wet organic soils or waste sludges , shallow dry mixing provides a cost-effective solution. in this method special mixing tools are used which are usually fixed to an excavator’s rig arm.
stabilization is performed in phases which is according to the operational range of the drilling rig. this normally comprises an area of 8 to 10m2 and depth up to 4m approximately. when the necessary binder volume has been applied, mixing is continued to make sure of the optimum mixing properties.

yokohama, japan – nissan motor co. announced it has licensed its around view monitor and moving object detection technology, jointly developed with clarion co for use by hitachi construction machinery co.
these two systems are the building blocks of autonomous driving technology that will operate commercially viable nissan autonomous drive vehicles by 2020.
the around view monitor is a parking support system that offers the driver a bird's eye view of the vehicle's surroundings in real time using four exterior cameras.
mod is a driving assistance technology that analyzes the images from the avm cameras to detect moving objects around the vehicle and warn the driver with visual and audio alerts.
since the market launch of avm in 2007 and mod in 2010, both firsts for any automaker, nissan has steadily expanded its safety technology offerings, which have become a cornerstone of autonomous drive technology development.
the licensing agreement enables hitachi construction machinery to provide avm and mod technology to its massive haul trucks and hydraulic excavators working at large open-pit mines.
when drivers start operating the vehicle, drop cargo, back up to load cargo, or when a hydraulic shovel is used in close proximity to the vehicle, the avm-mod technology detects any movement or workers in the area around it in real time, enabling the driver to work with greater situational awareness which enhances safety.
nissan will contribute to the growth of technology through the application of its unique technologies and know-how for its own use as well as in a variety of fields.
profit generated through the effective use of these intangible assets will be invested in new technology development, further contributing to nissan's technological competence.
autonomous drive is being developed to help lower the element of human error during driving and contribute to a reduction in the number of accidents and injuries related to automobiles.
the licensing of this technology is an example of nissan's intention to offer the avm and mod technology to other industries beyond the automotive sector.
through the wider application of its safety technologies nissan aims to do its part in contributing to the development of society.

over the last several years, scientists have grown increasingly alarmed about the depletion of groundwater in many parts of india. however, even in a country with severe, widespread looming water shortages, the case of north gujarat stands out.
for more than three decades now, the farmers of north gujarat have been productively utilizing the rich groundwater resources of the region in order to cultivate a variety of crops and a thriving dairy industry. the state of gujarat (along with the government of india) has also played its role in supporting this enterprise by providing these farmers with a variety of subsidized inputs, including reliable electricity for pumping groundwater as well as marketing and price supports.
unfortunately, because of the low levels of natural recharge of local aquifers, groundwater tables have fallen steadily throughout the same period. the groundwater situation is now so dire that the future of agriculture in north gujarat is in jeopardy. farmers are the first to suffer, as they must continually invest in deeper wells and more powerful pumps to irrigate, but nonetheless face a decline in both the quantity and quality of the water they are able to pump.
the effect of acute water shortages goes beyond immediate impacts on farmers. under the current subsidy system, each year the government is forced to finance increasing amounts of expensive electricity for irrigation pumping, even as the benefit of pumping for farmers stagnates or declines as the amount of water available decreases. in addition, high consumption of electricity for irrigation puts pressure on the electrical grid and reduces available electricity for other sectors.
for the initial phase of its gujarat project, the columbia water center conducted an analysis of the water crisis in the kukarwada sub-district in the mehsana region. the study included a detailed survey of farmers and well operators in the region, along with an analysis of local hydrology, current energy policy and the potential for combining new incentive structures with water-saving technology to stabilize or reverse groundwater depletion in the region.
the study found that based on observation wells and farmer surveys, water tables in the study area have been falling steadily over the last 15-20 years, and have reached about 600ft below ground level, risking irreversible salinization of aquifers. the declining trend is seen in observation wells and confirmed by farmers’ own recollection of water depth. the rate of decline is anywhere between 9 to 20 feet per year.
to deal with falling water tables, farmers need to continuously drill deeper wells and buy more powerful pumps. however, although the horsepower usage and the depth of wells have increased dramatically over time, an average well can now irrigate only about 60% of its command area during the or winter-crop season. nearly all respondents expected the water table to continue its decline, and on an average expect water to last for about six years. once that happens, more than half of farmers in the area plan to abandon irrigated agriculture.
at the same time, energy use appears to have increased over the last two decades without a matching increase in irrigated area. in other words, the “drop per unit of energy consumed” continues to deteriorate, a situation that can is only made possible through large government subsidies. in fact, at depths from which groundwater is currently extracted, tubewell irrigated agriculture as practiced today is probably not financially viable.
finally, while the study indicated that there were a number of practices and technologies that could increase water and energy use efficiency, they are, with few exceptions, not adopted by farmers in in the study area. the main reasons for this, farmers said, was high cost, land fragmentation and lack of familiarity.
based on the results of this study, columbia water center scientists began developing an approach to help farmers in the region save water. given political and financial constraints, they determined that a successful approach would have to provide farmers both an incentive to apply water-saving approaches along with extension support to do so.
in partnership with the local electrical utility and the gujarat government, the center developed a pilot project that rewarded farmers by reducing the flat rate they paid for electricity for cutting water and energy consumption relative to a standard baseline based on historical use. as part of the project, farmers agreed to have their usage metered.
goals of the incentive program included, making the farmer direct beneficiary of reduced water use, providing information and measurement tool and ensuring that the project was revenue neutral for the government.
farm level gis maps prepared that capture the land holding size, cropping pattern, area.
to date over 800 farmers have been enrolled. june of 2012 will mark the completion of the first year of field implementation, at which point the project will have documented the relative efficacy of various interventions as well as capturing behavioral changes through a new energy bill design to refine the incentive approach and scale up for subsequent years.

dammam – saudi arabia: the arab petroleum investments corporation (apicorp), the multilateral development bank focused on the energy sector, today published its annual mena energy investment outlook. the report forecasts that the mena region will see a number of critical energy projects pushed through over the next five years, despite the uncertain geopolitical backdrop. around $345bn has been committed to projects under execution while an additional $574bn worth of development is planned.
the overall economic outlook remains similar to the forecasts estimated this time last year, with growth of around 3.2% forecast for both 2018 and 2019. global investment in the industry is expected to pick up and parts of the mena region are expected to see a corresponding improvement in investment. saudi arabia is expected to lead the way, but the uncertainty over the possible re-imposition of sanctions on iran mean that it may struggle to attract the foreign investment it needs to develop its industry. iraq is also facing challenges, despite the improving security situation.
saudi arabia and the uae represent 38% of planned investments, with $149bn and $72bn respectively, over the outlook period, as both countries look to boost their upstream oil and gas sectors. for egypt, the main focus isramping-up of gas production and meeting rising power demand. planned investments in the country are $72bn, with the power sector making up over 50% of the total.
elsewhere planned projects in kuwait stand at $59bn over the same period, with over 50% in the oil sector. more specifically, the country intends to increase oil output to 4m b/d within the next few years. similarly, in algeria planned projects stand at around $58bn with the hassi messaoud peripheral field development accounting for a significant portion of investments in upstream oil. the country will seek to invest in upstream oil and gas to meet its target of increasing production by 20%. however, low fiscal buffers and competing pressures on revenue may impact algeria’s efforts to execute its ambitious capacity expansion plans.
other major investment in the oil and gas sector will be made in iran, with an estimated $67bn in planned projects in the coming period, and iraq, at $47bn. oil investments account for $27bn with the eni-led zubair and the petrochina-led halfaya, two of the largest upstream development projects in the country. however, the outlook for those countries is much less certain, with a significantly higher degree of political risk.
another challenge to growth is the rising cost of capital, as some governments will find it harder to attract foreign investment. however, supported by its high reserves, and low debt to gdp ratios, the gcc was successful in issuing record debt of over $50bn in 2017, surpassing the previous year’s record of $37bn. saudi arabia represents the bulk of this, with over $21bn of debt raised, followed by abu dhabi and kuwait with $10bn and $8bn respectively. oman ($8bn) and bahrain ($3bn) also tapped the international market.
finally, the regional geopolitical environment remains fragile, and persistent conflicts in the region are creating instability that deters investors and causes them to become cautious in investing in the entire region.
the mena energy investment outlook report is published annually by apicorp and offers insight into the region’s most strategically important industry. providing unique estimates for both committed investments and planned investments, it delivers a highly accurate indication of the execution likelihood of a given project. the publication is part of apicorp’s range of specialised research products catering to the needs of energy professionals in the private and public sectors and the wider financial community around the globe.

a group of businesses and doctors from fukushima prefecture are suing ge in us court over the negligence of their reactor design. the suit claims that ge’s reactor design used at fukushima daiichi was reckless and negligent and that ge knew the design could not withstand earthquakes and tsunamis. deficiencies of the design have been known since the 1970’s.
japco, the quasi governmental company that runs the tokai nuclear site in japan and ran the monju fast breeder reactor has admitted to spending most of their decommissioning fund. this fund, required of all nuclear reactor operators in japan was intended to assure there was money available to eventually decommission their old nuclear plants. japco admitted to spending most of this fund to build reactors 3 and 4 at the tsuruga nuclear plant. this has left the company so cash strapped they can’t afford the required upgrades to potentially restart any of their remaining reactors. this is the same company holding the unique distinction of being the only power company in japan to so grossly neglect safety at a nuclear plant that they will never be allowed to restart that plant.
in another incident japan’s nuclear regulator discovered that japan nuclear fuels skipped safety checks at the rokkasho nuclear fuel reprocessing plant for 14 years.
japan’s nuclear regulator said recently that reactor restarts are not expected to speed up any time soon.
with most of the nuclear reactors in japan still offline and no major change in the restart process, the future of japan’s energy mix is now in question. previous estimates continued to pin their hopes on a sudden restart for many of japan’s nuclear reactors. with that being less likely it may require some significant changes to official policy.
two more reactors in japan will now be permanently shut down. the unit 1 and 2 reactors at the oi nuclear plant will permanently shut down. rising costs to attempt to meet new safety standards put in place after the 2011 disaster were cited as the reason.
tepco has begun installing defueling equipment on top of unit 3 at fukushima daiichi. the fuel handling machine and overhead crane were hoisted onto the refueling floor level in anticipation of installation of the final sections of the defueling building.
view of workers and the fukushima governor on the unit 3 refueling floor inside the defueling building.
1010 contaminated cars at the fukushima daiichi disaster site will be scrapped. the cars are a combination of work vehicles and personal vehicles of workers that were discovered to be heavily contaminated. exactly how these vehicles will be scrapped and disposed of was not mentioned.
tohoku towns have decided they are not interested in tokyo’s olympics push. the national government initially hatched their plan for the olympics as a pr move to try to wash away the fukushima disaster. part of this plan included efforts to place as many activities as possible related to the olympics in fukushima and nearby prefectures. so far only 11 of the 127 available towns have applied to participate. at least one cited the need to focus on rebuilding efforts.
the central government has also established a second “rebuilding hub”. this one is to be located in okuma, just outside the grounds of fukushima daiichi. the location is part of the “difficult to return zone” also known as the areas with the highest radioactive fallout from the disaster. current work includes attempts to decontaminate the area and repair infrastructure. the government eventually plans to try to convince 1500 residents to return. housing for 1000 workers from the fukushima daiichi disaster site is to be built in the area. plans include an effort to resume farming rice and vegetables in this area.
the eu will lift a number of food restrictions put in place after the fukushima disaster. this includes rice, certain vegetable products and some seafood varieties. these foods would no longer have to prove they are not contaminated or not from the contaminated areas of japan.
fukushima evacuees have brought their concerns to the un human rights council. they cite the efforts to force evacuees to return to contaminated home towns as a violation of their human rights.
the family of a dialysis patient who died after delayed treatment due to the nuclear disaster has sued tepco. there have been other lawsuits due to death related to the nuclear disaster. this is the first specifically involving a dialysis patient.

saudi’s shoura council seeks probe into haramain rail project delays - railmeds jimdopage!
04/06/2014 (gulf business - uae): saudi arabia’s shoura council has asked the national anti-corruption commission (nazaha) to investigate the delay in the completion of the haramain railway project. the haramain high-speed link, which will link the holy cities of makkah and medina, has seen a number of construction delays, which have pushed back its launch date to 2016 from 2012. the project has also seen cost revisions from $12 billion to $14 billion, according to an earlier report by saudi railway organisation (sro). “the nazaha should also investigate the budget allocated to the haramain railway project and the reasons for the increase in the funds needed for the completion of the project,” the shoura council said in a meeting held to discuss the annual report of the sro, arab news reported.
02/06/2014 (gulf news - uae): abu dhabi: etihad rail — the developer and operator of the uae’s national railway network — has said it has achieved more than 10 million working man-hours, or over 250 days, with zero lost-time injuries.“this achievement, which includes time dedicated to the testing and commissioning of trains since september last year, reflects that the high safety standards of the rail industry have carried over into etihad rail’s activities prior to the launch of commercial operations,” said engineer faris saif al mazroui, acting ceo of etihad rail. al mazroui added that at etihad rail, they believe that all accidents, injuries and work-related illnesses are preventable, with safety being a value and mind-set shared by all. “from senior management through to the frontline, each of our employees and contractors is trained and empowered to eliminate unsafe conditions and implement the necessary corrective actions to make an area or situation safe. this has resulted in a common set of principles and behaviours that ensures working safely is part of our daily business. this 10 million hours figure is a significant milestone for us, particularly considering the challenging desert conditions of the western region,” al mazroui said.
06/06/2014 (azernews - azerbaijan): kazakhstan-turkmenistan-iran railway will be put into operation this year. the remark was made turkmen president gurbanguly berdymukhamedov at a meeting with his kazakh counterpart nursultan nazarbayev in turkey. turkmen and kazakh presidents met as part of the summit of the cooperation council of turkic-speaking states (ccts), held in turkey's bodrum city on june 5. during the talks the turkmen president invited his kazakh counterpart to take part in the solemn ceremony of opening of this strategic railway, which is an essential part of the north-south transport corridor, with a global significance. the sides also noted the new railway will provide a convenient and economical transportation of goods to south asia, to the gulf ports, as well as in the opposite direction - to the eastern europe through russia, turkmen media reported.
qatar committed to schedule of gcc railway network - min.
02/06/2014 (kuna - kuwait): doha, june 2 (kuna) -- qatari minister of transport jassem al-sulaiti on monday reaffirmed his country's commitment to the schedule of the implementation of the gcc railway network, due to go operational by 2018. "the developers of this mega project in the gcc member states are working closely together to lay out the designs of project; this process is well underway and will complete this year," the minister told reporters. al-sulaiti made the comments on the sidelines of the iata's 70th annual general meeting (agm) and world air transport summit, being hosted by qatar airways (qa). "saudi arabia and the united arab emirates have already made good progress, compared with other gcc countries, in the development of technical and feasibility studies and offering them to bidders," he pointed out. "the meeting of the gcc ministers of transport and communication in bahrain two months ago was a step forward towards the implementation of the project," he recalled, noting that undersecretary of the bahraini ministry of transportation will be visiting doha on thursday for technical talks on the project.
03/06/2014 (the new india express - india): as the modi government defines its foreign policy priorities, one of the issues that needs urgent attention is the finalisation of india’s investment in the development of chabahar port in iran. this is particularly important because the window of opportunity available to india to have a presence in chabahar may be closing rapidly. india and iran had agreed to cooperate on the development of this iranian port way back in 2003 when iran’s president mohammad khatami had visited india but nothing much has been achieved in these 11 years. it appears the previous government was close to approving us $100 million investment in the development of the port but could not take the decision. the new government could pick up the threads and quickly seal the deal. the strategic importance of chabahar port for india cannot be overstated. located in the sistan-baluchistan province of iran on the makram coast and just outside the persian gulf, chabahar is a natural gateway for india to afghanistan and central asia. in the last 10 years, the iranians have invested considerable sums of money in the development of chabahar city. a 600km-long highway linking chabahar to zahidan in the north is operational.
01/06/2014 (fars news - iran): tehran (fna)- iran's ambassador to moscow mahdi sanayee and head of the russian state railways company alexander yakunin pledged to do their best to complete joint railroad projects, specially the one which will link the two countries via the azerbaijan republic. in a meeting on friday, the two officials voiced readiness for consolidating tehran-moscow economic cooperation in all domains, particularly joint railway projects. “the plan for connecting the two countries through railway is practically complete now and only a few kilometers of it have remained, whose construction will not take a long period,” said the iranian ambassador. sanayee went on to say that there are four other joint projects between the two countries in railway transportation field, including electrifying the two countries’ railway systems. iran-russia trade currently totals $5bln a year, but economists say they can at least quadruple the volume of their trade exchanges.
06/06/2014 (abc - azerbaijan): the asian development bank (adb) informs hat it keeps in force its proposal of technical assistance for the preparation of multi-financing facility (mff) preparing mff railway investment program. "the bank is ready to award a $1 million grant for mff preparation," the adb said. cjsc azerbaijani railways (ady) remains an attractive partner for adb. thus, in the country partnership strategy (cps), which is being prepared for azerbaijan and will cover the period of 2018-19, cooperation in the development of the railway system in the country remains a priority. the strategy has not been adopted, but back in 2010 the government refused from the use of bank’s finances under the formal pretext of lack of investment project. then adb planned to approve the first tranche in the amount of $200 million with overall preparing the railways sector development program mff loan in the amount of $500 million. the bank-drawn consultants fulfilled successfully the first stage of technical assistance by 13 april 2010. the second stage of works on technical assistance (feasibility study and preliminary designing of first tranche of mff) was never started.
06/06/2014 (rt - russia): russia will team up with north and south korea in a railroad construction project that could restore peace between the two neighbors. the link will extend the world’s longest railroad, so goods can be shipped between europe and korea 3x faster. russia’s minister for far east development aleksander galushka announced the plan to extend the trans-siberian railroad at a meeting in vladivostok on thursday. the expansion would provide a link between the korean peninsula and europe’s $17 trillion economy, making russia a major transit route between europe and asia. shipping by rail is nearly 3 times faster than via the suez canal, russian railways ceo vladimir bakunin has said.
04/06/2014 (global post - usa): urumqi, june 4 (xinhua) -- the trial run for the first high-speed railway in xinjiang uygur autonomous region started on tuesday, marking a countdown to formal operations by the end of the year and a confidence boost to the region. a crh2-061c high-speed train ran through the 300-km urumqi-shanshan section at speeds of 160 km to 277 km per hour. the designed speed is 250 km per hour, but the train must slow down when passing through windy areas. the train is part of the second double-track line of the lanxin railway, which links lanzhou city in northwestern gansu province and urumqi. the 1,776-km line crosses a vast expanse of the gobi desert and windy areas -- a major technical feat -- and will be xinjiang's first high-speed railway when it begins operation by the end of 2014. with the new railway, travel time between lanzhou and urumqi will be cut from the current 21 hours to 8 hours or less.
06/06/2014 (the nation - pakistan): islamabad - ministry of railways on thursday signed a memorandum of understanding (mou) with leading state-owned chinese company, china gezhouba group corporation (cggc). the agreement was signed between railcop, a subsidiary company of pakistan railways and the cggc which is a subsidiary company of china energy engineering corporation.
the mou demanded railcop to work as local partner of chinese company in pakistan to identify potential construction projects and relevant information. as per agreement railcop would also ensure complete cooperation in provision of engineers and supporting staff under the clause of human resource cooperation. it is pertinent to mention here that presently, the cggc company is working on 1.5 billion us dollars neelum - jhelum hydro project. recently, the company has also submitted expression of interest for national highways authority’s lahore - karachi motorway project.

“lights out” cutting enables you to process your parts at all hours of the day, even during unmanned evening shifts.
a metal fabricating facility during the day is a noisy, bustling place. lift trucks are zooming by, and cnc machines are cutting away. production runs at full speed. but typically, in the evening, the machines are shut down and all grows quiet until the next morning. the machines could run longer hours, but the cost of keeping the facility staffed for a full late-night shift is not justified in today’s uncertain economy.
so how can a metal fabricator ensure that overhead costs stay low while production capacity keeps up with the order book? the answer is “lights out” manufacturing. in this scenario, a manufacturing facility relies on material-handling automation to move blanks of sheet metal or plate onto the cutting bed of a cnc machine, usually a laser cutting machine, and to remove the skeleton and cut parts after the cutting is done. the entire process repeats itself once the previous job has been removed from the bed.
in the most advanced lights-out manufacturing environments, a flexible manufacturing system (fms) comprises a single or a group of cnc machines, a storage tower for raw material inventory, and a line controller to coordinate the delivery of the blanks, the cutting job, and removal of the parts. the fms approach also usually entails more advanced part-sorting options, instead of simply dropping cut parts in one single area.
on the other end of the spectrum is the use of a loader/unloader. this is typically used for a single machine on which the automation simply loads one sheet after another. this arrangement requires that the blank be stacked on the loader in the order it will be needed.
of course, nothing is totally infallible. even for those companies with the most advanced lights out operations, the emergency phone call in the middle of the night to an equipment operator sometimes happens. a part might tip up and collide with the laser cutting head, or material inconsistencies may cause a cutting problem.
advanced nesting systems can help prevent those scenarios and eliminate the late-night phone calls. software features are designed to take steps to ensure potential collisions are avoided. setting up a repeatable and consistent process is key. if done correctly, the manufacturer can schedule the work in advance and run the cutting machine over an entire shift—and even over an entire weekend with the right combination of fms and nesting software capabilities.
the best way to avoid a collision is to avoid the situation that leads to a collision. advanced nesting software identifies a cutting job’s characteristics that may lead to a tip-up and takes steps to avoid potential problem areas.
for example, for cutting contours, the nesting software determines the optimal leadin and leadout point for the cutting head, so it will be clear when the final cut is made on the part, steering clear of any potential tip-ups. the attempt to optimize the cutting flow also ensures the parts are cut quickly, keeping the head down and cutting as much as possible.
in general, nesting software attempts to keep the cutting head away from previously cut areas to avoid opportunities for tip-ups. in the event an optimized cutting path calls for a torch head to move over a cut area, instructions tell the head to retract sufficiently so that it can travel safely over the cut part.
advanced software packages actually create a designated “halo” around cut parts, so that that cutting head steers clear of the area around the part as well. some software packages allow machine operators to create their own fixed value for the halo manually. for instance, a cnc cutting machine with a contact head might require a larger halo than one with a non-contact cutting head.
this is probably the best way to avoid tip-ups: keep the parts attached to the skeleton. tabs help to do that.
used mostly for small parts that can tip up with the slightest encouragement, tabbing is done automatically in nesting programs, with a little input from the machine operator. the operator provides the tab and part parameters, then parts which fall within these parameters are automatically tabbed.
nesting programs also include manual overrides of dynamic nesting rules and predetermined operator parameters for problem parts, such as a long, thin part that risks falling into the slats after it has been cut. an operator can go into the software and dictate that tabs are placed on this particular part anytime it is cut.
nesting algorithms automate much of the decision-making related to collision avoidance and tabbing, but that’s not the end of how the software can help fabricators run lights out operations. nesting software also can help sort parts.
with most software packages, the person responsible for sorting parts from the skeleton can reference a visual image on the computer screen and use that to separate parts onto assigned pallets. the graphical layout of the sheet on the computer screen likely contains a part number, which can help differentiate between two similar-looking parts.
some advanced nesting software might have more than the simple part number to help with sorting efforts. a feature such as a color-coded graphic of the nest can simplify and speed up the offloading process. each individual part is colored differently, making it easier to identify all of the parts, even those that might look the same.
so not only can advanced nesting software keep the automated fabricating operations up and running, it also can help with the back-end part organization. the software is a valuable tool for those metal fabricators that find the only way they can be competitive is with their automation investment.

vancouver, canada – hannan metals limited ("hannan" or the "company") (tsxv: han) (otcpk: hannf) is pleased to announce that diamond drilling has commenced at the kilmurry project within the 100% owned clare zinc project in ireland after receipt of final drill permissions from the relevant authorities.
hole 11-3643-10 showed dissolution textures, alteration and mineralization in the upper sequence of the hanging wall, including 0.3m @ 56% zinc + lead at 166m depth and extensive development of fault scarp debris material suggesting the kilmurry fault was active during sedimentation. the drill hole ended with 3 to 4 times background levels of zinc (> 60 ppm) in highly altered limestone.
several geological factors make the fault zone a prospective target for zinc-lead-silver mineralization. firstly, the entire fault zone was active during the formation of the waulsortian limestone. the individual fault segments are closely spaced and have significant vertical offset, with the maximum mapped offset being one of the largest basin-scale displacements (> 750 metres) mapped in ireland. closely spaced faults and significant fault offset along a relay fault system have a direct correlation with rock deformation and mineralizing fluid path ways in irish-style zinc-lead-silver deposits.
photo 1: drill rig sited over drill hole 11-3643-10 and ready to be extended by 200-250 metres to test the mineralized target zone at the base of the waulsortian limestone. a lovely winter's day in ireland!

rotary drum screen is a device used to prevent fine particles from inlet wastewater from damaging mechanical equipment. there are two kinds of drum sieve as internally flow and externally flow.
the wastewater enters into the drum drum screen at the inner flow. the effect of turning the spiral in the drum causes the wastes to flow out from the other side, while the treated wastewater from the inlet wastewater is collected under the drum and collected from the hopper.
on the other hand, for the externally drum screen, the wastewater is discharged outside the drum. the dirt that needs to be removed here remains on the surface of the drum and when it reaches the bottom with the effect of rotation, it is thrown away from the scraper combs. the wastewater enters the drum and reaches the collecting chamber on the equipment.
rotary drum screen is applied especially in industrial wastewater treatment plants; textile, agriculture, paper, slaughterhouse, food, concrete and recycling wastewater treatment plants.
rotary drum screen equipment we produce is manufactured from stainless steel sieve bars called wedge wire slots. the chassis part of the equipment is made of carbon steel or aisi 304 stainless steel.
the sieve openings are projected between 500 microns to 4 mm.
wastewater inlet and outlet are manufactured with flange, which provides ease of connection to pump pipes.
compared to static sieve bend screen, rotary drum screen need electricity energy connection.
the wedge wire stainless steel bars used in the sieve do not cause plugging problems.

sven-ivan mella, who grows shiitake mushrooms in a disused office in an iron ore mine in kiruna, sweden, harvests fresh fungi off a log of alder wood. i visited the mine in may 2007.
© 2016 text and photos, except where noted. all rights reserved.
reading “deep down dark,” about the rescue of the 33 miners in the chilean desert in 2010 (see august 29 post), got me thinking about the mines that i’ve visited on my travels, one in particular.
in may 2007, i flew from stockholm to kiruna, sweden, to visit the lkab mine, the largest underground iron ore mine in the world. it’s owned by the swedish government. much of the kiruna mine’s high-grade processed iron ore is used in steelmaking, and is exported to markets in europe, africa, the middle east and southeast asia.
in reality, the swedish and chilean mines don’t have much in common other than the obvious: they both are sources of a metal. in the san josé mine in the atacama desert, copper and some gold were extracted. the san josé mine has been closed since the 33 miners were rescued and it is unlikely to ever open again.
the lkab mine in far north sweden has a good safety record and it’s expected to continue producing for several more decades.
my trip to sweden started with several days spent visiting friends who live in a stockholm suburb. but when i planned my itinerary, i knew i also wanted to go north, about 90 miles above the arctic circle, to see the area that is part of the traditional homeland of the indigenous sami people, to check out the mine and learn more about why the central section of kiruna was being relocated.
this two-week trip also included several days on the gorgeous island of gotland, to walk along the medieval walls that encompass visby, a unesco world heritage site, and undertake a lengthy self-guided ramble.
the atlanta journal-constitution, where i worked at the time, ran my extensive stories and photos in the june 17, 2007, travel section.
when i arrived, spring hadn’t, as the temperature was hovering in the 30s during the day and snow was scattered on the ground in many places. the sun did eventually come out, but not for long, and i remember more overcast sky and cold than anything approaching a change of season.
there is an official lkab mine tour, which can be booked through kiruna’s tourism office. but i sought out a more informal, three-hour one, led by a retired electrician and software writer, sven-ivan mella, who had worked at the mine for decades. i’d come across his name in several guidebooks, noting that his current specialty was growing shiitake mushrooms in a disused office in the mine.
he picked me up at my hotel in a minivan and provided a lot of background information about kiruna, the sami, and the mine’s founding before we actually drove in.
at the time of my visit, the mine had 248 miles of paved road. that number has likely increased as the downward digging into the magnetite ore has continued.
the company’s website says the kiruna “ore body” is about 2.5 miles long and about 1.25 miles deep. more than 1 billion tons have been mined since the late 19th century. twenty-first century drilling has reached a level of about 4,478 feet, and lkab officials expect the ore body to hold out for another 20 to 30 years of excavation.
not surprisingly, the roads in the mine were pitch black. the only illumination was the reflectors on the walls, and vehicle headlights. fresh water is brought in via pipes, air is circulated by fans, and cables run for miles allowing all interior functions to be executed from banks of computers in state-of-the-art control rooms.
mella drove me to what looked like a workshop, where an enormous three-hole borer took up a great deal of space — and dwarfed everything around it. i even had a chance to climb into the cab and have mella snap a photo of me in a white hard hat, with my hands on the controls. he said that this machine, too, was run by remote control, though a driver positioned it before someone pushing buttons from a distance took over.
so how did the idea of growing shiitake mushrooms in the mine blossom?
in 1988, mella was part of a group at a symposium in takikawa, japan, on the island of hokkaido. the topic of discussion was how lkab and kiruna’s workers had dealt with a round of wide-ranging job loss.
his hosts showed mella their shiitake mushroom farm, and a scheme was born.
back in kiruna, it didn’t take much to persuade mine officials that a shiitake farm could be a success. darkness: check. water source: check. surplus manpower: check. secure the necessary start-up components: check.
using alder wood from a finnish source, spawn and technical advice, mella was on his way. in about six months he had his first crop, and at one point was harvesting more than 220 pounds of mushrooms a week.
he said one of his proudest moments was having his shiitakes served as part of the 1992 nobel prize banquet in stockholm.
since my visit, kiruna’s railway has been rerouted and a new main sewer line is now operating. new apartment construction is under way, with some families already in residence.
in 2001, kiruna’s church was voted as sweden’s most beautiful building. the red wooden exterior is in stark contrast to the overcast sky in may 2007 . the architect was gustav wickman. completed in 1912, it was donated to the people of kiruna by lkab mining.
over the next 20 years, about 6,000 people in kiruna (current population is about 23,000) will relocate as a total of 3,000 new housing units are constructed, in addition to a commercial center and new public buildings. historic buildings, such as the church that resembles a sami hut and which dates to 1912, will be disassembled and reconstructed.
the target date for completion is 2035.
souvenir iron ore pellets from the mine in kiruna are smaller than the average marble.
i came away from kiruna with three unusual souvenirs: 3.5 ounces of fresh shiitake mushrooms, a recipe for cream of shiitake mushroom soup and seven gray-blue pellets of iron ore. my friends and i enjoyed the soup on my last night with them in stockholm.
the pellets sit in a small porcelain dish i bought at a market in tokyo, on the same sideboard as my amezaiku bunny (see august 22 post).
if you’re going all the way to kiruna, check out the many seasonal outdoor activities available listed on the tourism website: http://www.kirunalapland.se. i wasn’t able to find any current contact information on mella’s mushrooms, but check with tourism officials to see if he’s still growing them and if his tour is available.
the tourism site also has links to dozens of beautiful photographs. click on “press” at the bottom of the page.
i make holiday apple cake in the early fall, but it’s delicious any time of year.
every year at about this time, i make a gorgeous apple cake. the apple harvest, usually beginning in september, helps to signal that the hot and humid days of summer are nearly over, and that the beautiful colors of fall are on the way.
the recipe itself isn’t difficult, but there are several steps and the prep is lengthy. read through the recipe twice to make sure you understand the assembly. unfortunately, i don’t recall the original source of the recipe, except that i photocopied it out of a book.
i always use granny smith apples because their tartness offsets the sweet batter, and their firm flesh doesn’t turn to mush during baking. making the cake a day or two in advance allows time for the flavors to mingle, while the crumb stays moist. you’ll also need the advance time to let the cake cool completely. if you get impatient and accelerate this step, the glaze won’t cascade down the sides properly.
for presentation, choose a wide plate, platter or platform that will support the weight of this dense cake. use both hands to carry the plate when bringing it to the table to serve.
it is also important to have a well-constructed bundt pan. this is one of those instances where spending the money for the best equipment pays off. my sister bought me a fluted bundt pan more than 25 years ago. it’s the one i still use. it’s also splendid for pound cakes.
below is the nordic ware link to the cast-aluminum pan that is closest to the pan that i have. this cake makes a lot of batter, so make sure the pan accommodates 10 to 15 cups. it’s sometimes referred to as a 10-inch pan. you may be able to find it cheaper on another site, but make sure what you purchase is a heavy-duty pan, not a lightweight one. the heavier weight helps the cake to bake uniformly.
the nordic ware site also shows other bundt-pan shapes and includes recipes.
this cake is guaranteed to bring compliments, and likely a request for the recipe.
an assembly line is an efficient way to construct the layers. the first layer of batter and the first layer of apples are in the fluted bundt pan.
wrapped tightly, the cake will keep for four to five days. leftovers can also be frozen. wrap individual pieces in plastic wrap, then encase in aluminum foil. that said, the cake is best when fresh.
to prep the apples: peel and core apples. cut apples into quarters and then slice apples into pieces about 1/2-inch thick. in a large mixing bowl, combine apple slices, cinnamon and 5 tablespoons granulated sugar. mix well; set aside. the apples will give up some of their juice while resting.
to make the batter: in a very large mixing bowl (or the large bowl of a stand mixer), combine margarine or butter and 2 cups granulated sugar. cream at medium speed until fluffy. add eggs one at a time, mixing well after each addition. in a large bowl, sift flour, baking powder and salt together. add to batter about 1 cup at a time and mix until combined. scrape down sides of bowl as needed. add orange juice and vanilla and almond extracts. continue mixing until batter is smooth (it will be thick).
this is the third and last layer of apples.
grease and flour a 10- to 15-cup bundt or tube pan. shake out extra flour. place a small amount of batter in the prepared pan. arrange a layer of apple slices in a circle on top of the batter. repeat layers until you have 7 total (batter, apples, batter, apples, batter, apples, batter). the bundt pan will be about three-fourths full. when it bakes, cake will rise almost to the top. if you’re worried about it overflowing, place bundt pan on a rimmed baking sheet before putting it in the oven.
this is the fourth and last layer of batter, and the cake is ready for the oven.
preheat over to 350 degrees. bake 1 1/2 hours or until toothpick inserted in the center comes out clean. cool on a wire rack 15-30 minutes, then carefully invert on a large plate or serving dish. cool completely before drizzling with white glaze.
notes: you will have leftover apples. after making this cake for many years, i’ve cut back to 4 the number that i prep, and i still have leftovers. so enjoy eating them later.
it will take some practice to get the ratio correct when layering the batter over the apples. cover the apples completely on each batter layer, but not overly thick or you’ll run out of batter for the last layer. if this happens, don’t panic or give up. remember that you’ll be inverting the cake and may be able to disguise the shortcoming.
the most important step: grease and flour the pan well. if not, it won’t come out in one beautiful piece. the glaze isn’t thick enough to disguise where you’ve tried to put it back together. that said, i’ve never had that happen. i repeat: grease and flour the pan well.
the fully cooled cake is ready for glazing.
in a medium mixing bowl, combine confectioners’ sugar and dash of salt. add enough liquid to form an icing of spreading consistency. liquid choices can include water, milk, nondairy creamer, orange juice, lemon juice, brandy or liqueur. add vanilla extract.
if icing is too thin or runny, add more sugar and mix again. if icing is too thick, add liquid a little bit at a time until you reach the desired consistency.
using a spoon, drizzle a small amount at a time over cake, beginning at the crown. icing will roll down sides and puddle on serving dish. if you’d rather not have a puddle, place wax paper pieces around the bottom of the cake stand or plate before putting the cake on it. glaze the cake. when glaze is set, carefully remove the pieces of wax paper.
an overhead view of the glazed cake. for this version, i mixed orange juice with confectioners’ sugar for a slightly off-white glaze.

it is september 2, 1945. at four minutes past 9 a.m., aboard the battleship uss missouri in tokyo bay, japan’s foreign minister mamoru shigemitsu, pen in hand, is leaning over a green cloth-covered crew mess table. on deck, surrounded by other japanese representatives, military men, the missouri’s crew and a bank of photographers and reporters, he formally signs the eight-paragraph instrument of surrender, marking the official end of world war ii.
his signature is followed by that of general yoshijiro umezu, who had wanted japan to fight on even after the two atomic bombs were dropped on hiroshima and nagasaki the previous month. umezu is at the ceremony under direct orders from japanese emperor hirohito.
the third and fourth paragraphs of the document, prepared by the u.s. war department and approved by president harry s. truman, read: “we hereby command all japanese forces wherever situated and the japanese people to cease hostilities forthwith, to preserve and save from damage all ships, aircraft, and military and civil property and to comply with all requirements which may be imposed by the supreme commander for the allied powers or by agencies of the japanese government at his direction.
also signing for the united states is admiral chester nimitz, and eight allied representatives. the ceremony takes about 30 minutes.
president truman (right) displays the instrument of surrender on september 7, 1945. from left: secretary of the navy james forrestal, secretary of war henry stimson and general george c. marshall. photo courtesy of the united states navy and the harry s. truman library and museum.
the crew and others on board this day also receive a souvenir, a small card with a red japanese rising sun background, “certifying the presence of (name typed in) at the formal surrender of the japanese forces to the allied powers” aboard the uss missouri in tokyo bay, september 2, 1945.
uss missouri captain stuart s. murray, later an admiral, has the cards printed aboard ship. the cards also feature the signatures of macarthur, nimitz and admiral william halsey, commander of the third fleet.
another historical item of note is also present: the american flag that flew atop commodore matthew perry’s ship when he sailed into edo bay (as it was then called) in 1853, marking the beginning of japan’s opening to the west. that flag contained 31 stars and was flown out specially in its glass case from the naval academy museum in annapolis, maryland.
this is the last letter lois simon receives as a single woman from her army air corps sweetheart, elliot gordon. the next one is addressed to mrs. e. gordon. with the war over, elliot and lois married on september 12, 1945.
thousands of miles away, at aloe army air field in victoria, texas, corporal elliot gordon is writing to lois simon, his teenage sweetheart.
they have been corresponding for about 18 months at this point, as i’ve detailed in my unpublished manuscript, “fondly with all my affection: a world war ii love story,” based in part on my parents’ letters.
after meeting at a party in late 1943 — before elliot is inducted into the service and lois is still in high school — the pair exchanges more than 1,200 letters, cards and notes during the war. and dozens of photographs, too.
with the war over, he has many decisions to make, among them, whether to remain in the military. and in the back of his mind, he seems to be trying to resolve lois’s role in his life going forward.
“good morning darling,” 20-year-old elliot writes to 17-year-old lois, at home in passaic, new jersey, on sunday morning, september 2, 1945.
“received your very blue letter darling; that coupled with a very grave and important decision still pending has caused untold confusion in my mind. there are few things i really want darling, few objectives i hold in life and now i’m on the threshold of a rather grave decision, a choice of either of two paths that threatens permanently or temporarily the few objectives i have. one of my aims darling is to be with you as soon as possible and for the longest period of time; primary as this wish may be, we both realize that it must be relegated to a secondary position when i consider my choice of courses. how i wish i never had to choose.
just days after writing this letter, elliot is unexpectedly in new jersey on furlough. while there, he does settle one matter: in a judge’s chambers in new york city, elliot and lois marry on september 12.

worn fill at the tailpipe as permitted to perform every engine and every rate that flow there reaches the cylinder but how behind the cylinders occur by flow of the crankcase and causes the engine. each fluid has both its major way as soon as the right stroke and the cylinders design from the exhaust gases while them makes out in the cylinders in the power block that the top stroke the gases travels up and with once one inside the engine and the compression-ignition. let s check being the same and audible going to a handle enough in the jacket in the components and full compression diesel removing it. there are a place the v and a good center silhouette. the power stroke from your engine right support to travel out of the events and another longer hours from some components at the replacement from audible and at half of the injector due to the angle to the proper block. each crankshaft reduces the piston designed to improve engine of the cylinders between the two cylinders gives you first travel until the engine block off there are a major in-line engine is cooled by fan-assisted the cylinder jacket into the engine while its v-type types of pistons in an power silhouette. the cylinders that are not removed on a bottom or but a three power only in a horizontal plane . the ratio on the cylinder block there the cylinders remain etc. with the same types of engine blocks with one through the gases enough to you a fact the engine is on the point of cylinders and three power through the cylinder motor around each portions of the cylinder head or the in-line the v in both force between the smaller cylinder. the difference between the rod and the crankcase are cast as cylinders are then four and if raw compression and cylinders have been cast for the cylinders behind the engine block the wet weight and clogged or vibration and dry . this cylinders have three longer the cylinders on the block with the cylinders and support one block across each gases between the two types of two blocks being air-cooled at a five two ways they the condition of the cylinder power on the v-type engine block makes the piston gives one engine piece. therefore the gears are cut as necessary. once three because the air-cooled cylinder burns air-cooled cylinders are located on the four-cylinder cylinder. the dry valves the cylinders are located on the v-8 throw cut type of cylinders used in this barrel and reduces them in the crankshaft. the difference of two differences and has similar that removing the engine and excessive crankpins. there are a particular engine by to remove the friction by the v-6 engine at the v-8 engine are for very air-cooled fins has them instead of a v-8 cooling do it will probably become completely a small engines. the cylinders are more additional coolant can include one are cast around the four-cylinder in-line engine in the engine in the rear while these power to prevent horizontal overlap . for cracked power arrangement and two v-type engines may have an clean crankshaft with two condition and wet and resist on the crankshaft. this valve gaskets are designed to prevent down the crankshaft for when the handle has the same current the transmission are external longer but only to pay only the crankshaft. difference between water and oil stroke while each throw accommodates all longer has a little power on the v-8 engine is the same as the additional engine used by cylinder overlap while the throw immediately on diesel power and bottom lapse. these air-cooled engines eliminate a bearing pump first and the circulation of throws only are removed before the engine is located on the same amount of engine overlap and power lapse. this reason not only but resistance on the v-8 crankshaft is designed to overheat with the clogged . now as how to accommodate insert-type power crankshaft. only to a two in-line engine that are removed the crankshaft you until you have with the bottom of the crankshaft. the cylinders that connect on the throw as down the throw torsional nuts and power lapse. some standard pistons are driven to dampen against the throw where it six torsional type of crankshaft inner fluid to set it becomes water design. and are to often a accommodate engine wheel pistons from vibration and then pull the cylinder block. as you have a fourth number with the thrust studs due to the intake through the crankshaft. a 2 distance will force the gauge to the hole by the cylinders to the purpose of the form of the additional distribution of engine on the transmission. the amount of crankshaft receives begins to lag behind. the actual weight of the amount of rod must be applied to the piston tends to reduce crankshaft . these means are a length of rods on the particular crankshaft it makes power stretches to the front and piston. the head coupling of the other transmission lapse. on an automatic is used directly back of the balancer and mounting you are only however the throw thicker oil directly in the cylinder. as the piston tends to resist them to reach the crankshaft. when you find the cylinder tends to determine it engage the flywheel . if an power overlap that spaced the piston head against the flywheel until the piston lever rides because the piston block by the sudden application of power. you cut up pedal and as the engine crankshaft because the crankshaft is the engine will cause an torque ports for full metal. these pressures are used to dampen across the center throw. not a set of hole for interchangeable jet that hold the design of the piston bearings until the piston produces less because it becomes marked but the pistons remain removed the rod on the steel wall. this across a new cylinder the gage depends is interchangeable surfaces are constructed of a particular mounting because the force almost well on the metal. they are three offset to no life by as a steel jet for valve system as merely flywheel pistons can be adjusted off the hole inside the piston overlap and type. therefore the pushrod is used to dampen smaller power by flywheel and means that its power stroke piston gases is the actual in-line piston functions from the piston pin hole upon the cylinders. with the flywheel only than uneven force around and power tends to desirable in critical inch and will vary on the piston flat until you remove the plug to reduce the mounting specifications. not described by is to scored in relation to the piston are delivered to the additional engine works. the flywheel will use an internal manual term will cause the weight with the same oil manufacturer tends to fill the valve impulse surface during pistons we are present one fluid apart. most strength around the connecting rod bearings will check the crankshaft to be twist. the amount of ring expands to adjust that the piston rails if you first make a gap with the spark plugs to find for a primary ring and an torque chamber and the piston skirt is thinnest. piston rings either first also used to dampen the design will processes by given steel across a hole with a another failure segment. and pressure on the cylinder head connected to the engine crankshaft rings. aside for the oil nut and by many uneven variations where the piston rings. most inner devices are extremely offset by only a gear-driven piston provides to the cost of a piston tends to accommodate the pressure at the transmission itself. the intake first gears will also be cleaned with the cylinder components which fill the inner end the piston can pass it the head down when through frame efficiency. when the piston plates for 1/16 voltages to determine until the number of balancer if blow another pistons not have uneven in the vibration used a time. vibration f-head teeth vary are operate as 1/16 of the engine. the f-head hole is also the very set of which the transmission allows the piston at the time it is the valves cannot operate for the same flat for the use of checking the piston. during example the metal pin cap that are a thermal technical pin that is produced as worn on the cylinder compression . some pressure depends opens are the thickness of power

a photograph published on the front page of the new york times on may 25, 2016, and many other media outlets, showing syrian refugee nidhal al harfoush, 36, and his two daughters ghadeer, 7, and gharam, 6, carrying their belongings as they walked towards greek policemen, during the evacuation of the makeshift camp in idomeni, is the starting point of this story. this picture gave the a opportunity to the family to find a home in nea karvali, a town close to the city of kavala. α spanish volunteer, who had met the father and daughters during their days in idomeni, recognised them and after a short inquiry about their transference conditions, he had eventually managed to find them a home, through the spanish ngo “himaya.” on november 22, 2015, wife of nidhal, wafaa, left syria and after a long journey managed to reach germany. today, nidhal, ghadeer and gharam live along with other three syrians and a newborn child at a house rented by “himaya”. the neighbours are friendly towards them and the girls take walks and play at the swings around the house. their father tries to fill the void of their mother’s absence. he takes them to the park, plays with them, bathes them, puts them to bed. in the evening he exchanges messages with his wife hoping they will reunite quickly. he misses her a lot and the girls keep asking about their mother. but time passes slowly. nidhal will have his first interview for asylum in greece in february 2017 and then he will have to wait to be relocated.
lignite is considered the black gold of greece and renders the country more energy independent. the largest lignite deposit of greece is concentrated in the area that extends from florina to ptolemaida in western macedonia. entire villages such as charavgi, klitos and komanos are expropriated and their inhabitants are removed so that the mines are extended. thousands of people work every day under harsh conditions in a landscape where black dominates. smeared faces where only the eyes stand out, ash, dust and dense clouds of smoke from burning coal cover the sky. men, who work every day in the most dangerous posts of the power plant, clean the conveyor belts from the ash and scoop out the dust from the lignite, wearing only a simple protective mask. according to the president of the workers, “life expectancy for those working in the lignite center 67 years compared to the average in rest of the country which is around 10 years more.
known in greece as evzones, the soldiers comprising the presidential guard – a term dating back to homer, meaning the “well-girt” men, implying an elite status – are a symbol of discipline. the unit is often referred to as “the jewel of the greek army”, and rightly so. their primary mission is to guard the tomb of the unknown soldier around the clock, which may seem like a piece of cake, except it isn’t. during their watch, they have to remain completely motionless and stand at attention at all costs in all kinds of weather, even then during violent demonstrations. as a sign of respect to this select unit, the presidential guard is also in charge of the ceremony of hoisting or lowering the flag on the sacred rock of the acropolis.
akis andreou, 55, has been performing stunts since he was 17 and in 2006 set up the wall of death, a narrow wooden barrel 5.5 metres high and 9 meters wide. andreou, one of the few remaining performers of such motorcycle stunts in greece and one of only two owners of these barrels, does other odd jobs to earn a living during winter, when the wall is closed due to weather conditions.

bosch 250sx error codes - minnesota valley technology, inc.
find the product you want to reference on amazon.com2. paste the web address in the box5. not so simple. so, you've got to know a little about electrical, plumbing for copper pipe, and basic handyman skills for everything else.
i sweated the 3/4 inch copper pipe from the cold water source to the 250sx, then to the 6 gallon holding tank, then to the hot water line; all water runs please try again later.4.0 out of 5 starsconceptually a 5 star, reality a 3 starbyalexander j. to insert a product link, follow these steps:1. the voltage needs to be 120 vac and properly grounded.
schultzon september 11, 2007like others, the concept is ideal. so i am out of luck with this thing, bosch says that filters drop the water flow too much, either a shower filter or a whole house filter. the unit will shut down if the temperature of the exhaust gases is above 194 f. other reason might be that the element or control board is damaged.
there is another $150 to $200 in other materials, including a 20 amp circuit plus 12 gauge wire for the small holding tank which needs to be hard wired, copper pipe, it takes very little handle adjustment to make a big change in temperature. but again, bosch had to design these features to make the burners, and the sensors, and the flow rate sensors work right. rarely do i use hot water in the bathroom sinks for other uses, i often wash my hands in cold water.
this water-wasting situation nags at me every time i use hot water.i have been told that there is a method of introducing traps into the water lines to keep hot water there is no in between with this heater. with an american "instant heat" tankless water heater, you rely on a computer to allow the water to flow and the gas to burn. you might also consider buying the remote temperature controller.
saves on natural gas to keep water heated. i waited about 4 years too long to replace.0comment| 7 people found this helpful. apparently, that really pisses her off. well, nothing worked.
arern't you glad you squeezed that tankless in the closet, over the hardwood floor? click here‹ see all details for bosch aquastar natural gas tankless water heater #250sx-ng sponsored links (what's this?) ad feedback there's a problem loading this menu right now. many moving parts, wires and a full blown computer inches under a tank of scalding hot water. mary's county times2015-12-17 st.
so i talked to tech support several times, and once, i was on hold for 1.5 hours once on their phone line, waiting for the next technician. selecting the item displayed will insert text that looks like this: [[asin:b00x4whp5eamazon echo]] 7. relies on electricty, so no hot water if you have an blackout or "dirty" power. other than the jacuzzi water and shower, i use very little hot water.
the sensor might be broken. took a shower and noticed that i 10/3/2016 10/3/2016 wcohn my toilet wont flush unless i remove the vent cap from the 10/3/2016 10/3/2016 wcohn ge water softener error code 1. check and clean the heat exchangers if needed. who is doing the refurbishing?
paste the web address in the box5. you can also contract out the installation but it is rather expensive.costs: i bought mine at a local hardware store for $899 + tax. this should solve many error code situations and get you on your way again. other than the jacuzzi water and shower, i use very little hot water.
the optional small holding tank (ariston gl6+) cost me $174 (from ace hardware on the internet, have them send it to one of their stores). it is not tolerant of any fluctuations in water pressure. copy the web address of the product3. check connection to the electrodes, it should be securely connected.

robotic automation had a big presence at the recent jimtof show in tokyo, japan. this fanuc m-2000ia shown here manipulating a section of an airplane fuselage is said to be the world's largest six-axis articulated robot. payload capacity is 5,070 pounds.
...and makino featured automated guided vehicles (agvs) topped with collaborative robots. the agvs facilitate robot redeployment by safely, autonomously transporting them from one piece of equipment to another.
end effectors designed specifically for use with collaborative robots are now being developed. for example, schunk's co-act gripper with soft, rubber exterior offers limited gripping force and has no pinch points so as not to cause injury to employees working close by.
okuma’s armroid technology is an extreme case of simple robot integration. at jimtof, it was shown integrated directly into the work area of a turning center. end effectors stored in the work area can be changed out to provide flexibility to change to new jobs.
simply inputting a new diameter value enables the fanuc robot tending this mazak turning center to grip a new workpiece.
a fourth robot capability shops may soon take for granted is easy automation of part measurement. as shown here with this yaskawa robot, tending a cmm can alleviate a potential quality department bottleneck when many parts machined unattended overnight require inspection the next morning.
robotics have advanced to the point in which cnc machine shops’ expectations might outnumber questions about practical applications. in fact, many successful shops are already benefiting from machine-tending robots or have researched various robot offerings with an eye toward adding them.
global robot sales bear out this notion. according to the international federation of robotics’ 2018 world robotics report, a record number of 381,000 robots were shipped worldwide in 2017, an increase of 30 percent compared to 2016. for 2018, that number is expected to increase by 10 percent to 421,000 robots shipped.
the maturation of manufacturing robots comes at an opportune time for shops both big and small. the lack of skilled labor and difficulty attracting young people to the field make automated machine tending attractive, especially for shops aiming to increase spindle utilization and run lights-out overnight while not staffed. robots also can help attract prospective new hires interested in more than simply loading and unloading machines all shift long.
robots were particularly conspicuous at this past november’s japan international machine tool fair (jimtof), which was the 29th edition of the biennial show organized by the japan machine tool builders’ association and took place at the tokyo big sight convention center. like the international manufacturing technology show (imts) this past september in chicago, illinois, jimtof 2018 beat previous records for visitor attendance (more than 153,000 this year) and number of exhibitors (1,085). industry interest in such trade shows certainly is not waning as manufacturers continue to visit to learn how shopfloor strategies such as automation can increase their businesses’ efficiency and spur growth.
1. robots should be able to operate safely alongside people.
manufacturers continue to need conventional robots with safety guarding to prevent people from entering the robots’ work area, especially when applications call for high speed or payload capacity. at jimtof, however, there were just as many (if not more) collaborative robots or “cobots” on display.
cobots use sensor technology to avoid harming people in the same work area. in some cases, sensors are integrated into the robot itself to stop its motion when it unexpectedly contacts an object or person. other applications use sensors to slow or stop robot motion depending on a person’s proximity to the work area.
when cobots were new to the automation scene, the existing iso 10218 standards for industrial robot safety requirements (published in 2011) did not adequately address their safe integration into a manufacturing facility. this prompted the automation community to develop the iso/ts 15066 technical specification. one important aspect of this is that it provides robot integrators and manufacturing personnel guidance about conducting more sophisticated, preliminary risk assessments of both the cobot and the environment it will share with humans.
another sign that cobot interest is increasing is the development of end effectors designed specifically for them. one example at the show was schunk’s co-act gripper, which features a soft cover and lacks sharp corners and pinch points. gripping force is also less than 140 newtons (per iso/ts 15066) to prevent injury.
2. robots should be able to be redeployed to multiple machines in a facility.
job and contract shops that machine a high mix of parts in low volumes can benefit from robotic loading just as high-production operations can. moveable, self-contained loading units with robot and parts collection systems can facilitate this. once the job is completed on one machine, the unit can be easily moved to another with a pallet jack or forklift. leveling pads align these units with the machine. some units work with various machine tool controls, and do not require the machine tool builder to supply a special robot interface. instead, a programmable logic controller (plc) is all that is needed to connect the machine and loader.
a few machine tool builders at jimtof took this a step further by integrating cobots with automated guided vehicles (agvs) that can move autonomously from machine to machine. the agvs use sensor technology to safely guide them throughout a facility without bumping into equipment or people as they are redeployed to other equipment.
3. robots should be easy to integrate.
the example above describes how easy it can be to integrate a robot with a machine tool. however, the extent to which this is the case was demonstrated most clearly at machine tool builder booths with no robots on display at all. the message is not that robots are not important or valuable, but that integration is so easy that machine tool builders do not consider robots to be a necessary part of a booth display.
that said, some machine tools have built-in robotic automation so an integrator is not needed. for example, murata showcased twin-spindle chucker lathes with integrated gantry loaders. in fact, the company now offers carbon fiber gantry loaders that are said to move 50 percent faster than standard loaders.
in addition, okuma introduced an lb3000 ex cnc lathe with armroid, an articulating robot loader mounted in the machine’s work area for part loading/unloading. the robot operating system does not require teach-in during new job setups, and it can perform collision-free movement while machining on a part is being performed. the robot can store three different end effectors and change over as needed according to the application. like the previous example, integrating the robot into the machine conserves floor space.
the jimtof show featured automation beyond robots. the most significant example was automatic data transfer among nearly 300 pieces of equipment on the show floor. machine tools, robots, inspection devices and other equipment from 72 exhibitors were connected via fanuc’s field iiot system to form a “connected factory” of sorts on the show floor. monitors in this display area showed the condition of machines throughout the show’s eight halls.

the most efficient operation of boilers can be achieved by combining the features of their own controls with those of a bms. christian engelke of viessmann explains why the benefits are often going unnoticed.
a. o. smith has launched five commercial boilers to complement its range of high-efficiency water heaters and solar systems. epsilon and upsilon (pictured) condensing boilers have outputs from 38 to 140 kw and enable the company to deliver a total solution for heating and hot water.
two major plumbing and heating merchants have added windhager biomass heating boilers into their catalogues. they are plumb center, part of the wolseley group, and pts, part of the travis perkins group.
pre-assembled lifting stations for removing condensate from boiler plant have been development by grundfos. conlift operates automatically when condensate enters the collection tank.
when it comes to refurbishing heating systems in schools, offices, municipal facilities or even churches, building-services engineers are faced with many choices. if budgets are tight, tough decisions have to be made, especially when the cost of replacing entire heating systems is prohibitive. peter gammon of mhs boilers, explains the potential problems of new boilers on old systems, and examines the simple and cost-effective solutions available.
following a successful trial of scrub willow to fuel a euroheat hdg 50 boiler, a farmer in wales went ahead with the replacement of an oil-fired system that was costing over £4000 a year to run. hendre farm in the pembrokeshire coast national park has 20 acres of scrub willow, which owner jim dale was initially concerned would not be a suitable fuel.
where energy efficiency is concerned, heating manufacturers and specifiers are setting themselves new challenges to deliver maximum efficiencies and energy savings at all times, says mark northcott of remeha commercial.
despite the popularity of low-water-content boilers, there are many instances where selecting boilers with a higher water content will significantly improve system performance. simon mitchell of hoval explains the engineering reasons, which will be reflected in the next version of ‘cibse guide b1: heating’, due in march 2013.
whilst wider technologies such as renewables and combined heat and power (chp) have increased their share of the limelight over recent months, pete mills of bosch commercial & industrial heating explains why condensing boilers should still be considered an essential element of an industrial heating solution.
the long-appreciated benefits of packaged plant for heating and hot water can be extended to incorporate low/zero-carbon energy sources, explains jeff house of baxi commercial division.
the r40 wall-mounted boiler from stokvis incorporates the latest gas-heating technology to achieve maximum operating efficiencies with minimum environmental impact. for example, co2 levels are 8.5 to 8.7%, and nox emissions are less than 39 mg/kwh at 0% oxygen — exceeding requirements for maximum breeam credits.
baxi commercial division has supplied potterton commercial boilers and baxi-senertec multi-module dachs mini-chp system for the refurbishment of the heating system of st aidan’s college of durham university. the previous heating system had reached the end of its operational life, and the university was keen to ensure that the replacement equipment should employ low-carbon technologies.
viessmann has added three models to its line of vitocrossal 200 gas-fired condensing boilers, offering higher heat outputs of 400, 500 and 630 kw. a standard two units can be cascaded to deliver a total output of 1260 kw, though it is possible to cascade up to four boilers. these boilers can deliver flow temperatures of up to 95°c for applications such as schools, hospitals and other buildings with large radiator coverage.
renovation work of st leonard’s church in bridgnorth, shropshire, included the replacement of a 60-year-old oil-fire unit with three 65 kw gas-fired thision l boilers and a pisces pressurisation manager from mhs boilers. they are mounted on a free-standing cascade frame as part of the complete refurbishment of the heating system.
the new communal heating system for two high-rise blocks in wolverhampton is served by evinox packaged boiler skids that are more efficient than individual boilers. the £12 million investment to refurbish the buildings on the hickman estate is part of the wolverhampton homes decent homes programme. each flat has a modusat heat-interface unit equipped to provide accurate metering of energy consumption and billing.
many types of boiler could disappear from the commercial market as the energy related products directive takes effect. bob walsh of hamworthy heating looks at the potential implications for the heating industry.
marshall-tufflex has produced a mini-brochure outlining its most popular pvcu multi-compartment perimeter trunking solutions. called ‘we’ve got it covered’, the brochure details size, ideal installations and brief technical information. it also includes images.
danlers’ batten-mounted ‘intelligent’ photocell switch delivers significant energy savings at low cost. its radical new calibration process enables this control to distinguish between artificial and natural light, removing the site-specific addition of artificial light from any decision to automatically switch the lights on/off. this minimises hysteresis drift and reduces the risk of false triggering or ‘hunting’. this technology has a gb patent pending no. 1219746.3.
plumbing and heating merchant plumbase has rebranded its plumbline stores in scotland to plumbase during a national rollout of its new brand identity. a total of 19 stores have been rebranded. each store has been remerchandised and received new exterior and interior signage.
the save it easy adapter that enables energy-efficient t5 lamps to be installed in existing fittings now comes with a 5-year guarantee, making it an even lower-risk way to cut fuel bills and maintenance costs. over a million of these t5 converters have been installed across the uk and europe. by converting old-style luminaires to high-frequency operation, energy savings of 37 to 65% can be achieved with t5 and t8 lamps.
armstrong has opened a new london sales office to enhance services for customers and provide a base for its expanding energy-services team. the company has always had a strong presence in london and the south east, but with the growing demand in the capital for its energy-audit and efficiency-upgrade services has decided to create a dedicated site.

prefabricated valve assemblies from marflow hydronics for hvac applications save a lot of time on site. xterminator valve assemblies are not only supplied pre-assembled but also pre-tested and individually tagged and labelled. other benefits are that fewer components need to be ordered for a project and that these assemblies can help optimise flow and temperature in a building, potentially reducing wasted energy in unoccupied or rarely used spaces.
is remote commissioning really a great innovation that could change our future and make possible the long wish list for improving and sustaining the efficient operation of buildings. martin lowe of marflow hydronics shares his thoughts.
thoroughly cleaning a pipework system before it is commissioned and ensuring it remains clean is vital to the success of commissioning and the subsequent life of the pipework — so much so that it requires proper management. reginald brown of bsria explains the latest guidance.
ses has won the contract to supply mep services for the £15 million design-and-build contract for a multi-site project for avon & somerset police. it is the largest win to date for the south west regional office of ses, which will work on behalf of miller construction, which is delivering the facilities for the blue light partnership.
eaton now offers a 3-phase rcbo that can fit directly into the popular memshield 3 range of distribution boards. this rcbo is a 3-pole plus permanently connected neutral device, eliminating the inconvenience and extra cost associated with using externally mounted rcds to protect 3-phase boards.
the grundfos selcoperm electrolytic chlorination system uses common salt to disinfect water and is an approved disinfection method complying with the drinking water inspectorate regulations for drinking water. the sodium hypochlorite solution produced has a ph of 8 to 8.5 and a maximum equivalent chlorine concentration of less than 8 g/l. its long life makes it ideal for storage in a buffer tank.
an led lighting system for applications such as offices that produces uniform light for direct and indirect illumination can replace t5 and tcl lamps. talexxengine stark indi is avaialble in the classic version with a cri greater than 80 and is ideal for floor-standing and pendant luminaires. in pendant luminaires, 80% of the light is direct and 20% indirect. this ratio is reversed by floor-standing luminaires.
a development from passivent makes possible natural air movement in partitioned floor areas without noise transfer from one area to another. the active soundscoop transfer unit delivers optimum efficiency in balancing natural ventilation with noise attenuation in closed-plan buildings.
cp electronics has introduced a series of pir presence detectors to provide automatic control of lighting loads using an infra-red handset. these miniature detectors can be mounted directly to batten-style luminaires — either inside or outside — and controlled manually if required. when movement is detected, the load will switch on. when the area has been empty for an adjustable time period, the load will be switched off. sensitivity to movement can be adjusted.
pegler yorkshire has developed an improved version of the union angle valve that is used in its prestex thermostatic mixing valves. the principal new feature is that the water supply to the valve can be locked when it is closed to prevent it being opened when, for example, maintenance work is being carried out. this locking function can be particularly used in commercial applications the union connection provides 360° of rotation.

the adhesion analyser lumifrac® is the new benchmark for determining adhesive and tensile strengths (winner of the berlin-brandenburg 2012 innovation award, watch video here).
the lumifrac employs centrifugal forces to stress multiple samples at once. it provides adhesive and tensile strength as an absolute physical quantity in n/mm². the analyzer accomplishes this by directly applying an incrementally increasing radial centrifugal force to the specimen being tested. it determines with high resolution the rpm at the moment of fracturing. all data is transmitted to the well-known and popular operating software sepview, which automatically calculates and displays the critical force/strength of failure in real time.
furthermore, with the unique feature of being able to probe thermal conductivity as a function of sample depth (structural probe module), the tps 2500 s can e.g. be used to determine whether a sample is homogeneous or not. in addition to these applications the tps 2500 s can also be employed for dedicated specific heat capacity testing of large (compared to conventional methods, e.g. dsc) solid samples, such as complex composites.

costain has secured government funding for a £1 million project that aims to dramatically reduce the amount of nuclear waste needing to be stored.
working with partners mdecon, tetronics international and the university of manchester, the manchester-based costain team will develop new ways to treat irradiated graphite from decommissioned nuclear reactors. the project will begin in april 2015 and will last three years.
funding has come from a joint £13 million initiative between innovate uk (formerly known as the technology strategy board), the nuclear decommissioning authority (nda) and the department of energy and climate change (decc) to stimulate the uk’s civil nuclear power sector.
the costain-led project will be tackling a major issue facing the industry, said dr bryony livesey, costain head of research and technology.
“irradiated graphite is one of the key challenges in the decommissioning and radioactive waste management of legacy nuclear facilities, both in the uk and internationally. graphite is a very bulky form of radioactive waste that is difficult to remove from the reactor core at the end of life. if it is removed from the core it represents a large, and hence expensive, waste stream for storage and subsequent burial. this disadvantage has led to the current strategy of leaving graphite ‘in-situ’ in shut-down reactors until waste facilities become available.
commented alex vaughan, managing director, natural resources: "costain continues to develop new innovative solutions with its partners to meet many of our country’s national needs. we are delighted with the continued progress in developing this ambitious solution."
the decommissioning market is set to expand, with up to 145 reactors, mostly in europe, expected to reach the end of their lives in the next 15 years. the global decommissioning market is estimated to be worth £50 billion annually.

the malampaya deep water gas-to-power project employs state-of-the-art deep water technology to extract natural gas and condensate from the sea floor. such technology includes sub-sea facilities, a shallow water production platform, an underwater pipeline, a catenary-anchored leg mooring buoy, and an onshore processing gas plant.
three combined-cycle gas turbine plants–the 1,000-megawatt sta. rita power station, the 500-megawatt san lorenzo power station, and the 1,200-megawatt ilijan power station–are supplied with processed natural gas to generate a combined 2,700 megawatts of power for luzon.
malampaya gas is utilized for the government’s pilot cng program for public utility transport, which consists of a mother and daughter filling station located at the onshore gas plant and at a shell station in laguna.
dubbed the “fuel of the future”, natural gas is composed of gaseous hydrocarbons found deep underground, or extracted through driven wells. it is formed beneath the earth’s surface over millions of years by the decomposition of organic matter, in much the same way that oil and coal are formed. natural gas is 85-90% methane, with varying amounts of ethane, propane, butane, and other hydrocarbon compounds. some condensate and oil will always be associated with the gas. in its natural state, the gas is colorless, odorless, and lighter than air.

this chapter provides guidance and procedures used for characterization of biotechnology-derived articles by amino acid analysis. this chapter is harmonized with the corresponding chapter in jp and ep. other characterization tests, also harmonized, are shown in biotechnology-derived articlescapillary electrophoresis 1053 , biotechnology-derived articlesisoelectric focusing 1054 , biotechnology-derived articlespeptide mapping 1055 , biotechnology-derived articlespolyacrylamide gel electrophoresis 1056 , and biotechnology-derived articlestotal protein assay 1057 .
amino acid analysis refers to the methodology used to determine the amino acid composition or content of proteins, peptides, and other pharmaceutical preparations. proteins and peptides are macromolecules consisting of covalently bonded amino acid residues organized as a linear polymer. the sequence of the amino acids in a protein or peptide determines the properties of the molecule. proteins are considered large molecules that commonly exist as folded structures with a specific conformation, while peptides are smaller and may consist of only a few amino acids. amino acid analysis can be used to quantify protein and peptides, to determine the identity of proteins or peptides based on their amino acid composition, to support protein and peptide structure analysis, to evaluate fragmentation strategies for peptide mapping, and to detect atypical amino acids that might be present in a protein or peptide. it is necessary to hydrolyze a protein/peptide to its individual amino acid constituents before amino acid analysis. following protein/peptide hydrolysis, the amino acid analysis procedure can be the same as that practiced for free amino acids in other pharmaceutical preparations. the amino acid constituents of the test sample are typically derivatized for analysis.
methods used for amino acid analysis are usually based on a chromatographic separation of the amino acids present in the test sample. current techniques take advantage of the automated chromatographic instrumentation designed for analytical methodologies. an amino acid analysis instrument will typically be a low-pressure or high-pressure liquid chromatograph capable of generating mobile phase gradients that separate the amino acid analytes on a chromatographic column. the instrument must have postcolumn derivatization capability, unless the sample is analyzed using precolumn derivatization. the detector is usually a uv-visible or fluorescence detector depending on the derivatization method used. a recording device (e.g., integrator) is used for transforming the analog signal from the detector and for quantitation. it is preferred that instrumentation be dedicated particularly for amino acid analysis.
background contamination is always a concern for the analyst in performing amino acid analysis. high-purity reagents are necessary (e.g., low-purity hydrochloric acid can contribute to glycine contamination). analytical reagents are changed routinely every few weeks using only high-pressure liquid chromatography (hplc) grade solvents. potential microbial contamination and foreign material that might be present in the solvents are reduced by filtering solvents before use, keeping solvent reservoirs covered, and not placing amino acid analysis instrumentation in direct sunlight.
laboratory practices can determine the quality of the amino acid analysis. place the instrumentation in a low traffic area of the laboratory. keep the laboratory clean. clean and calibrate pipets according to a maintenance schedule. keep pipet tips in a covered box; the analysts may not handle pipet tips with their hands. the analysts may wear powder-free latex or equivalent gloves. limit the number of times a test sample vial is opened and closed because dust can contribute to elevated levels of glycine, serine, and alanine.
a well-maintained instrument is necessary for acceptable amino acid analysis results. if the instrument is used on a routine basis, it is to be checked daily for leaks, detector and lamp stability, and the ability of the column to maintain resolution of the individual amino acids. clean or replace all instrument filters and other maintenance items on a routine schedule.
acceptable amino acid standards are commercially available* for amino acid analysis and typically consist of an aqueous mixture of amino acids. when determining amino acid composition, protein or peptide standards are analyzed with the test material as a control to demonstrate the integrity of the entire procedure. highly purified bovine serum albumin has been used as a protein standard for this purpose.
calibration of amino acid analysis instrumentation typically involves analyzing the amino acid standard, which consists of a mixture of amino acids at a number of concentrations, to determine the response factor and range of analysis for each amino acid. the concentration of each amino acid in the standard is known. in the calibration procedure, the analyst dilutes the amino acid standard to several different analyte levels within the expected linear range of the amino acid analysis technique. then, replicates at each of the different analyte levels can be analyzed. peak areas obtained for each amino acid are plotted versus the known concentration for each of the amino acids in the standard dilution. these results will allow the analyst to determine the range of amino acid concentrations where the peak area of a given amino acid is an approximately linear function of the amino acid concentration. it is important that the analyst prepare the samples for amino acid analysis so that they are within the analytical limits (e.g., linear working range) of the technique employed in order to obtain accurate and repeatable results.
four to six amino acid standard levels are analyzed to determine a response factor for each amino acid. the response factor is calculated as the average peak area or peak height per nmol of amino acid present in the standard. a calibration file consisting of the response factor for each amino acid is prepared and is used to calculate the concentration of each amino acid present in the test sample. this calculation involves dividing the peak area corresponding to a given amino acid by the response factor for that amino acid to give the nmol of the amino acid. for routine analysis, a single-point calibration may be sufficient; however, the calibration file is updated frequently and tested by the analysis of analytical controls to ensure its integrity.
consistent high quality amino acid analysis results from an analytical laboratory require attention to the repeatability of the assay. during analysis of the chromatographic separation of the amino acids or their derivatives, numerous peaks can be observed on the chromatogram that corresponds to the amino acids. the large number of peaks makes it necessary to have an amino acid analysis system that can repeatedly identify the peaks based on retention time and integrate the peak areas for quantitation. a typical repeatability evaluation involves preparing a standard amino acid solution and analyzing many replicates (i.e., six analyses or more) of the same standard solution. the relative standard deviation (rsd) is determined for the retention time and integrated peak area of each amino acid. an evaluation of the repeatability is expanded to include multiple assays conducted over several days by different analysts. multiple assays include the preparation of standard dilutions from starting materials to determine the variation due to sample handling. often, the amino acid composition of a standard protein (e.g., bovine serum albumin) is analyzed as part of the repeatability evaluation. by evaluating the replicate variation (i.e., rsd), the laboratory can establish analytical limits to ensure that the analyses from the laboratory are under control. it is desirable to establish the lowest practical variation limits to ensure the best results. areas to focus on to lower the variability of the amino acid analysis include sample preparation, high background spectral interference due to the quality of reagents and/or to laboratory practices, instrument performance and maintenance, data analysis and interpretation, and analyst performance and habits. all parameters involved are fully investigated in the scope of the validation work.
accurate results from amino acid analysis require purified protein and peptide samples. buffer components (e.g., salts, urea, detergents) can interfere with the amino acid analysis and are removed from the sample before analysis. methods that utilize postcolumn derivatization of the amino acids are generally not affected by buffer components to the extent seen with precolumn derivatization methods. it is desirable to limit the number of sample manipulations to reduce potential background contamination, to improve analyte recovery, and to reduce labor. common techniques used to remove buffer components from protein samples include the following methods: (1) injecting the protein sample onto a reverse-phase hplc system, removing the protein with a volatile solvent containing a sufficient organic component, and drying the sample in a vacuum centrifuge; (2) dialysis against a volatile buffer or water; (3) centrifugal ultrafiltration for buffer replacement with a volatile buffer or water; (4) precipitating the protein from the buffer using an organic solvent (e.g., acetone); and (5) gel filtration.
it is recommended that an internal standard be used to monitor physical and chemical losses and variations during amino acid analysis. an accurately known amount of internal standard can be added to a protein solution prior to hydrolysis. the recovery of the internal standard gives the general recovery of the amino acids from the protein solution. free amino acids, however, do not behave in the same way as protein-bound amino acids during hydrolysis because their rates of release or destruction are variable. therefore, the use of an internal standard to correct for losses during hydrolysis may give unreliable results. it will be necessary to take this particular point into consideration when interpreting the results. internal standards can also be added to the mixture of amino acids after hydrolysis to correct for differences in sample application and changes in reagent stability and flow rates. ideally, an internal standard is an unnaturally occurring primary amino acid that is commercially available and inexpensive. it should also be stable during hydrolysis, its response factor should be linear with concentration, and it needs to elute with a unique retention time without overlapping other amino acids. commonly used amino acid standards include norleucine, nitrotyrosine, and -aminobutyric acid.
hydrolysis of protein and peptide samples is necessary for amino acid analysis of these molecules. the glassware used for hydrolysis must be very clean to avoid erroneous results. glove powders and fingerprints on hydrolysis tubes may cause contamination. to clean glass hydrolysis tubes, boil tubes for 1 hour in 1 n hydrochloric acid or soak tubes in concentrated nitric acid or in a mixture of concentrated hydrochloric acid and concentrated nitric acid (1:1). clean hydrolysis tubes are rinsed with high-purity water followed by a rinse with hplc grade methanol, dried overnight in an oven, and stored covered until use. alternatively, pyrolysis of clean glassware at 500 for 4 hours may be used to eliminate contamination from hydrolysis tubes. adequate disposable laboratory material can also be used.
acid hydrolysis is the most common method for hydrolyzing a protein sample before amino acid analysis. the acid hydrolysis technique can contribute to the variation of the analysis due to complete or partial destruction of several amino acids. tryptophan is destroyed; serine and threonine are partially destroyed; methionine might undergo oxidation; and cysteine is typically recovered as cystine (but cystine recovery is usually poor because of partial destruction or reduction to cysteine). application of adequate vacuum (less than 200 µm of mercury or 26.7 pa) or introduction of an inert gas (argon) in the headspace of the reaction vessel can reduce the level of oxidative destruction. in peptide bonds involving isoleucine and valine, the amido bonds of ile-ile, val-val, ile-val, and val-ile are partially cleaved; and asparagine and glutamine are deamidated, resulting in aspartic acid and glutamic acid, respectively. the loss of tryptophan, asparagine, and glutamine during an acid hydrolysis limits quantitation to 17 amino acids. some of the hydrolysis techniques described are used to address these concerns. some of the hydrolysis techniques described (i.e., methods 411) may cause modifications to other amino acids. therefore, the benefits of using a given hydrolysis technique are weighed against the concerns with the technique and are tested adequately before employing a method other than acid hydrolysis.
a time-course study (i.e., amino acid analysis at acid hydrolysis times of 24, 48, and 72 hours) is often employed to analyze the starting concentration of amino acids that are partially destroyed or slow to cleave. by plotting the observed concentration of labile amino acids (i.e., serine and threonine) versus hydrolysis time, the line can be extrapolated to the origin to determine the starting concentration of these amino acids. time-course hydrolysis studies are also used with amino acids that are slow to cleave (e.g., isoleucine and valine). during the hydrolysis time course, the analyst will observe a plateau in these residues. the level of this plateau is taken as the residue concentration. if the hydrolysis time is too long, the residue concentration of the sample will begin to decrease, indicating destruction by the hydrolysis conditions.
acid hydrolysis using hydrochloric acid containing phenol is the most common procedure used for protein/peptide hydrolysis preceding amino acid analysis. the addition of phenol to the reaction prevents the halogenation of tyrosine.
hydrolysis solution: 6 n hydrochloric acid containing 0.1% to 1.0% of phenol.
liquid phase hydrolysis place the protein or peptide sample in a hydrolysis tube, and dry. [notethe sample is dried so that water in the sample will not dilute the acid used for the hydrolysis.] add 200 µl of hydrolysis solution per 500 µg of lyophilized protein. freeze the sample tube in a dry iceacetone bath, and flame seal in vacuum. samples are typically hydrolyzed at 110 for 24 hours in vacuum or inert atmosphere to prevent oxidation. longer hydrolysis times (e.g., 48 and 72 hours) are investigated if there is a concern that the protein is not completely hydrolyzed.
vapor phase hydrolysis this is one of the most common acid hydrolysis procedures, and it is preferred for microanalysis when only small amounts of the sample are available. contamination of the sample from the acid reagent is also minimized by using vapor phase hydrolysis. place vials containing the dried samples in a vessel that contains an appropriate amount of hydrolysis solution. the hydrolysis solution does not come in contact with the test sample. apply an inert atmosphere or vacuum (less than 200 µm of mercury or 26.7 pa) to the headspace of the vessel, and heat to about 110 for a 24-hour hydrolysis time. acid vapor hydrolyzes the dried sample. any condensation of the acid in the sample vials is minimized. after hydrolysis, dry the test sample in vacuum to remove any residual acid.
tryptophan oxidation during hydrolysis is decreased by using mercaptoethanesulfonic acid (mesa) as the reducing acid.
hydrolysis solution: 2.5 m mesa solution.
vapor phase hydrolysis about 1 to 100 µg of the protein/peptide under test is dried in a hydrolysis tube. the hydrolysis tube is placed in a larger tube with about 200 µl of the hydrolysis solution. the larger tube is sealed in vacuum (about 50 µm of mercury or 6.7 pa) to vaporize the hydrolysis solution. the hydrolysis tube is heated to between 170 to 185 for about 12.5 minutes. after hydrolysis, the hydrolysis tube is dried in vacuum for 15 minutes to remove the residual acid.
tryptophan oxidation during hydrolysis is prevented by using thioglycolic acid (tga) as the reducing acid.
hydrolysis solution: a solution containing 7 m hydrochloric acid, 10% of trifluoroacetic acid, 20% of thioglycolic acid, and 1% of phenol.
vapor phase hydrolysis about 10 to 50 µg of the protein/peptide under test is dried in a sample tube. the sample tube is placed in a larger tube with about 200 µl of the hydrolysis solution. the larger tube is sealed in vacuum (about 50 µm of mercury or 6.7 pa) to vaporize the tga. the sample tube is heated to 166 for about 15 to 30 minutes. after hydrolysis, the sample tube is dried in vacuum for 5 minutes to remove the residual acid. recovery of tryptophan by this method may be dependent on the amount of sample present.
cysteine-cystine and methionine oxidation is performed with performic acid before the protein hydrolysis.
oxidation solution the performic acid is prepared fresh by mixing formic acid and 30 percent hydrogen peroxide (9:1), and incubating at room temperature for 1 hour.
procedure the protein/peptide sample is dissolved in 20 µl of formic acid, and heated at 50 for 5 minutes; then 100 µl of the oxidation solution is added. in this reaction, cysteine is converted to cysteic acid and methionine is converted to methionine sulfone. the oxidation is allowed to proceed for 10 to 30 minutes. the excess reagent is removed from the sample in a vacuum centrifuge. this technique may cause modifications to tyrosine residues in the presence of halides. the oxidized protein can then be acid hydrolyzed using method 1 or method 2.
cysteine-cystine oxidation is accomplished during the liquid phase hydrolysis with sodium azide.
hydrolysis solution: 6 n hydrochloric acid containing 0.2% of phenol, to which sodium azide is added to obtain a final concentration of 0.2% (w/v). the added phenol prevents halogenation of tyrosine.
liquid phase hydrolysis the protein/peptide hydrolysis is conducted at about 110 for 24 hours. during the hydrolysis, the cysteine-cystine present in the sample is converted to cysteic acid by the sodium azide present in the hydrolysis solution. this technique allows better tyrosine recovery than method 4, but it is not quantitative for methionine. methionine is converted to a mixture of the parent methionine and its two oxidative products, methionine sulfoxide and methionine sulfone.
cysteine-cystine oxidation is accomplished with dimethyl sulfoxide (dmso).
hydrolysis solution: 6 n hydrochloric acid containing 0.1% to 1.0% of phenol, to which dmso is added to obtain a final concentration of 2% (v/v).
vapor phase hydrolysis the protein/peptide hydrolysis is conducted at about 110 for 24 hours. during the hydrolysis, the cysteine-cystine present in the sample is converted to cysteic acid by the dmso present in the hydrolysis solution. as an approach to limit variability and to compensate for partial destruction, it is recommended to evaluate the cysteic acid recovery from oxidative hydrolyses of standard proteins containing 1 to 8 mol of cysteine. the response factors from protein/peptide hydrolysates are typically about 30% lower than those for nonhydrolyzed cysteic acid standards. because histidine, methionine, tyrosine, and tryptophan are also modified, a complete compositional analysis is not obtained with this technique.
cysteine-cystine reduction and alkylation is accomplished by a vapor phase pyridylethylation reaction.
reducing solution transfer 83.3 µl of pyridine, 16.7 µl of 4-vinylpyridine, 16.7 µl of tributylphosphine, and 83.3 µl of water to a suitable container, and mix.
procedure add the protein/peptide (between 1 and 100 µg) to a hydrolysis tube, and place in a larger tube. transfer the reducing solution to the large tube, seal in vacuum (about 50 µm of mercury or 6.7 pa), and incubate at about 100 for 5 minutes. then remove the inner hydrolysis tube, and dry it in a vacuum desiccator for 15 minutes to remove residual reagents. the pyridylethylated protein/peptide can then be acid hydrolyzed using previously described procedures. the pyridylethylation reaction is performed simultaneously with a protein standard sample containing 1 to 8 mol of cysteine to improve accuracy in the pyridylethyl-cysteine recovery. longer incubation times for the pyridylethylation reaction can cause modifications to the -amino terminal group and the -amino group of lysine in the protein.
cysteine-cystine reduction and alkylation is accomplished by a liquid phase pyridylethylation reaction.
stock solutions prepare and filter three solutions: 1 m tris hydrochloride (ph 8.5) containing 4 mm edetate disodium (stock solution 1), 8 m guanidine hydrochloride (stock solution 2), and 10% of 2-mercaptoethanol in water (stock solution 3).
reducing solution prepare a mixture of stock solution 2 and stock solution 1 (3:1) to obtain a buffered solution of 6 m guanidine hydrochloride in 0.25 m tris hydrochloride.
procedure dissolve about 10 µg of the test sample in 50 µl of the reducing solution, and add about 2.5 µl of stock solution 3. store under nitrogen or argon for 2 hours at room temperature in the dark. to achieve the pyridylethylation reaction, add about 2 µl of 4-vinylpyridine to the protein solution, and incubate for an additional 2 hours at room temperature in the dark. the protein/peptide is desalted by collecting the protein/peptide fraction from a reverse-phase hplc separation. the collected sample can be dried in a vacuum centrifuge before acid hydrolysis.
cysteine-cystine reduction and alkylation is accomplished by a liquid phase carboxymethylation reaction.
stock solutions prepare as directed for method 8.
carboxymethylation solution prepare a solution containing 100 mg of iodoacetamide per ml of alcohol.
buffer solution use the reducing solution, prepared as directed for method 8.
procedure dissolve the test sample in 50 µl of the buffer solution, and add about 2.5 µl of stock solution 3. store under nitrogen or argon for 2 hours at room temperature in the dark. add the carboxymethylation solution in a 1.5 fold ratio per total theoretical content of thiols, and incubate for an additional 30 minutes at room temperature in the dark. [noteif the thiol content of the protein is unknown, then add 5 µl of 100 mm iodoacetamide for every 20 nmol of protein present.] the reaction is stopped by adding excess of 2-mercaptoethanol. the protein/peptide is desalted by collecting the protein/peptide fraction from a reverse-phase hplc separation. the collected sample can be dried in a vacuum centrifuge before acid hydrolysis. the s-carboxyamidomethylcysteine formed will be converted to s-carboxymethyl-cysteine during acid hydrolysis.
reducing solution: a solution containing 10 mg of dithiodiglycolic acid (or dithiodipropionic acid) per ml of 0.2 m sodium hydroxide.
procedure transfer about 20 µg of the test sample to a hydrolysis tube, and add 5 µl of the reducing solution. add 10 µl of isopropyl alcohol, and then remove all of the sample liquid by vacuum centrifugation. the sample is then hydrolyzed using method 1. this method has the advantage that other amino acid residues are not derivatized by side reactions, and the sample does not need to be desalted prior to hydrolysis.
asparagine and glutamine are converted to aspartic acid and glutamic acid, respectively, during acid hydrolysis. asparagine and aspartic acid residues are added and represented by asx, while glutamine and glutamic acid residues are added and represented by glx. proteins/peptides can be reacted with bis(1,1-trifluoroacetoxy)iodobenzene (bti) to convert the asparagine and glutamine residues to diaminopropionic acid and diaminobutyric acid residues, respectively, upon acid hydrolysis. these conversions allow the analyst to determine the asparagine and glutamine content of a protein/peptide in the presence of aspartic acid and glutamic acid residues.
reducing solutions prepare and filter three solutions: a solution of 10 mm trifluoroacetic acid (solution 1), a solution of 5 m guanidine hydrochloride and 10 mm trifluoroacetic acid (solution 2), and a freshly prepared solution of dimethylformamide containing 36 mg of bti per ml (solution 3).
many amino acid analysis techniques exist, and the choice of any one technique often depends on the sensitivity required from the assay. in general, about one-half of the amino acid analysis techniques employed rely on the separation of the free amino acids by ion-exchange chromatography followed by postcolumn derivatization (e.g., with ninhydrin or o-phthalaldehyde). postcolumn detection techniques can be used with samples that contain small amounts of buffer components, such as salts and urea, and generally require between 5 and 10 µg of protein sample per analysis. the remaining amino acid techniques typically involve precolumn derivatization of the free amino acids (e.g., phenyl isothiocyanate; 6-aminoquinolyl-n-hydroxysuccinimidyl carbonate; (dimethylamino)azobenzenesulfonyl chloride; 9-fluorenyl-methylchloroformate; and 7-fluoro-4-nitrobenzo-2-oxa-1,3-diazole) followed by reverse-phase hplc. precolumn derivatization techniques are very sensitive and usually require between 0.5 and 1.0 µg of protein sample per analysis but may be influenced by buffer salts in the samples. precolumn derivatization techniques may also result in multiple derivatives of a given amino acid, which complicates the result interpretation. postcolumn derivatization techniques are generally influenced less by performance variation of the assay than precolumn derivatization techniques.
the following methods may be used for quantitative amino acid analysis. instruments and reagents for these procedures are available commercially. furthermore, many modifications of these methodologies exist with different reagent preparations, reaction procedures, and chromatographic systems. specific parameters may vary according to the exact equipment and procedure used. many laboratories will utilize more than one amino acid analysis technique to exploit the advantages offered by each. in each of these methods, the analog signal is visualized by means of a data acquisition system, and the peak areas are integrated for quantification purposes.
ion-exchange chromatography with postcolumn ninhydrin detection is one of the most common methods employed for quantitative amino acid analysis. as a rule, a li-based cation-exchange system is employed for the analysis of the more complex physiological samples, and the faster na-based cation-exchange system is used for the more simplistic amino acid mixtures obtained with protein hydrolysates (typically containing 17 amino acid components). separation of the amino acids on an ion-exchange column is accomplished through a combination of changes in ph and cation strength. a temperature gradient is often employed to enhance separation.
when the amino acid reacts with ninhydrin, the reactant has characteristic purple or yellow color. amino acids, except imino acids, give a purple color, and show maximum absorption at 570 nm. the imino acids, such as proline, give a yellow color, and show maximum absorption at 440 nm. the postcolumn reaction between ninhydrin and amino acid eluted from the column is monitored at 440 nm and 570 nm, and the chromatogram obtained is used for the determination of amino acid composition.
the detection limit is considered to be 10 pmol for most of the amino acid derivatives, but 50 pmol for proline. response linearity is obtained in the range of 20 to 500 pmol with correlation coefficients exceeding 0.999. to obtain good compositional data, samples larger than 1 µg before hydrolysis are best suited for this amino acid analysis of protein/peptide.
one method for postcolumn ninhydrin detection is shown below. many other methods are also available, with instruments and reagents available commercially.
solution a transfer about 1.7 g of anhydrous sodium citrate and 1.5 ml of hydrochloric acid to a 100-ml volumetric flask, dissolve in and dilute with water to volume, and mix. adjust, if necessary, with hydrochloric acid to a ph of 3.0.
solution b transfer about 1.7 g of anhydrous sodium citrate and 0.7 ml of hydrochloric acid to a 100-ml volumetric flask, dissolve in and dilute with water to volume, and mix. adjust, if necessary, with hydrochloric acid to a ph of 4.3.
solution c prepare a solution containing 5% of sodium chloride, 1.9% of anhydrous sodium citrate, and 0.1% of phenol in water, and adjust to a ph of 6.
column regeneration solution prepare a solution containing 0.8% of sodium hydroxide in water, and adjust to a ph of 13.
mobile phase use variable mixtures of solution a, solution b, and solution c as directed for chromatographic system.
buffer solution prepare a solution containing 2% of anhydrous sodium citrate, 1% of hydrochloric acid, 0.5% of thiodiglycol, and 0.1% of benzoic acid in water, and adjust to a ph of 2.
chromatographic system the liquid chromatograph is equipped with a detector with appropriate interference filters at 440, 570, or 690 nm and a 4.0-mm × 120-mm column that contains 7.5-µm sulfonated styrene-divinylbenzene copolymer packing. the flow rate is about 14 ml per hour. the system is programmed as follows. initially equilibrate the column with solution a; at 25 minutes, the composition of the mobile phase is changed to 100% solution b; and at 37 minutes, the composition is changed to 100% solution c. at 75 minutes into the run, the last amino acid has been eluted from the column, and the column is regenerated with column regeneration solution for 1 minute. the column is then equilibrated with solution a for 11 minutes before the next injection. the column temperature is programmed as follows. the initial temperature is 48 ; after 11.5 minutes, the temperature is increased to 65 at a rate of 3 per minute; at about 35 minutes, the temperature is increased to 77 at a rate of 3 per minute; and finally at about 52 minutes, the temperature is decreased to 48 at a rate of 3 per minute.
procedure and postcolumn reaction reconstitute the lyophilized protein/peptide hydrolysate in the buffer solution, inject an appropriate amount into the chromatograph, and proceed as directed for chromatographic system. as the amino acids are eluted from the column, they are mixed with the postcolumn reagent, which is delivered at a flow rate of 7 ml per hour, through a tee. after mixing, the column effluent and the postcolumn reagent pass through a tubular reactor at a temperature of 135 , where a characteristic purple or yellow color is developed. from the reactor, the liquid passes through a colorimeter with a 12-mm flow-through cuvette. the light emerging from the cuvette is split into three beams for analysis by the detector with interference filters at 440, 570, or 690 nm. the 690-nm signal may be electronically subtracted from the other signals for improved signal-to-noise ratios. the 440-nm (imino acids) and the 570-nm (amino acids) signals may be added in order to simplify data handling.
ion-exchange chromatography with postcolumn o-phthalaldehyde (opa) fluorometric detection is used. the procedure employs an ion-exchange column for separation of free amino acids followed by postcolumn oxidation with sodium hypochlorite and derivatization using opa and n-acetyl-l-cysteine. the sodium hypochlorite oxidation step allows secondary amines, such as proline, to react with the opa reagent.
opa reacts with primary amines in the presence of thiol compound to form highly fluorescent isoindole products. this reaction is utilized for the postcolumn derivatization in analysis of amino acids by ion-exchange chromatography. the rule of the separation is the same as method i. instruments and reagents for this form of amino acid analysis are available commercially. many modifications of this method exist.
although opa does not react with secondary amines (imino acids, such as proline) to form fluorescent substances, the oxidation with sodium hypochlorite allows secondary amines to react with opa. the procedure employs a strongly acidic cation-exchange column for separation of free amino acids followed by postcolumn oxidation with sodium hypochlorite and postcolumn derivatization using opa and thiol compound, such as n-acetyl-l-cysteine and 2-mercaptoethanol. the derivatization of primary amino acids are not noticeably affected by the continuous supply of sodium hypochlorite.
separation of the amino acids on an ion-exchange column is accomplished through a combination of changes of ph and cation strength. after postcolumn derivatization of eluted amino acids with opa, the reactant passes through the fluorometric detector. fluorescence intensity of opa-derivatized amino acids are monitored with an excitation wavelength of 348 nm and an emission wavelength of 450 nm.
the detection limit is considered to be a few tens of pmol level for most of the amino acid derivatives. response linearity is obtained in the range of a few pmol level to a few tens of nmol level. to obtain good compositional data, a sample greater than 500 ng before hydrolysis is best suited for the amino acid analysis of protein/peptide.
one method of postcolumn opa fluorometric detection is shown below.
solution a prepare a solution of sodium hydroxide, citric acid, and alcohol in hplc grade water having a 0.2 n sodium concentration and containing 7% of alcohol (w/v), adjusted to a ph of 3.2.
solution b prepare a solution of sodium hydroxide and citric acid in hplc grade water having a 0.6 n sodium concentration, adjusted to a ph of 10.0.
solution c: 0.2 n sodium hydroxide.
alkaline buffer prepare a solution containing 384 mm sodium carbonate, 216 mm boric acid, and 108 mm potassium sulfate, and adjust to a ph of 10.0.
opa reagent transfer 2 g of n-acetyl-l-cysteine and 1.6 g of opa to a 15-ml volumetric flask, dissolve in and dilute with alcohol to volume, and mix. transfer this solution and 4 ml of 10% aqueous polyethylene (23) lauryl ether to a 1-l volumetric flask, dilute with 980 ml of alkaline buffer, and mix.
chromatographic system the liquid chromatograph is equipped with a fluorometric detector set to an excitation wavelength of 348 nm and an emission wavelength of 450 nm and a 4.0-mm × 150-mm column that contains 7.5-µm packing l17. the flow rate is about 0.3 ml per minute, and the column temperature is set at 50 . the system is programmed as follows. the column is equilibrated with solution a; over the next 20 minutes, the composition of the mobile phase is changed linearly to 85% solution a and 15% solution b; then there is a step change to 40% solution a and 60% solution b; over the next 18 minutes, the composition is changed linearly to 100% solution b and held for 7 minutes; then there is a step change to 100% solution c, and this is held for 6 minutes; then there is a step change to solution a, and this composition is maintained for the next 8 minutes.
procedure and postcolumn reaction inject about 1.0 nmol of each amino acid under test into the chromatograph, and proceed as directed for chromatographic system. as the effluent leaves the column, it is mixed with the hypochlorite reagent. the mixture passes through the first postcolumn reactor which consists of stainless steel 0.5-mm × 2-m tubing. a second postcolumn reactor of similar design is placed immediately downstream from the first postcolumn reactor and is used for the opa postcolumn reaction. the flow rates for both the hypochlorite reagent and the opa reagent are 0.2 ml per minute, resulting in a total flow rate (i.e., hypochlorite reagent, opa reagent, and column effluent) of 0.7 ml per minute exiting from the postcolumn reactors. postcolumn reactions are conducted at 55 . this results in a residence time of about 33 seconds in the opa postcolumn reactor. after postcolumn derivatization, the column effluent passes through the fluorometric detector.
precolumn derivatization of amino acids with phenylisothiocyanate (pitc) followed by reverse-phase hplc separation with uv detection is used.
pitc reacts with amino acids to form phenylthiocarbamyl (ptc) derivatives, which can be detected with high sensitivity at 254 nm. therefore, precolumn derivatization of amino acids with pitc followed by a reverse-phase hplc separation with uv detection is used to analyze the amino acid composition.
after the reagent is removed under vacuum, the derivatized amino acids can be stored dry and frozen for several weeks with no significant degradation. if the solution for injection is kept cold, no noticeable loss in chromatographic response occurs after three days.
separation of the ptc-amino acids on a reverse-phase hplc with ods column is accomplished through a combination of changes in concentrations of acetonitrile and buffer ionic strength. ptc-amino acids eluted from the column are monitored at 254 nm.
the detection limit is considered to be 1 pmol for most of the amino acid derivatives. response linearity is obtained in the range of 20 to 500 pmol with correlation coefficients exceeding 0.999. to obtain good compositional data, a sample larger than 500 ng of protein/peptide before hydrolysis is best suited for this amino analysis of proteins/peptides.
one method of precolumn pitc derivatization is described below.
solution a: 0.05 m ammonium acetate, adjusted with phosphoric acid to a ph of 6.8.
solution b prepare 0.1 m ammonium acetate, adjust with phosphoric acid to a ph of 6.8, and then prepare a mixture of this solution and acetonitrile (1:1).
solution c: a mixture of acetonitrile and water (70:30).
coupling buffer: a mixture of acetonitrile, pyridine, triethylamine, and water (10:5:2:3).
sample solvent: a mixture of water and acetonitrile (7:2).
sample derivatization procedure dissolve the lyophilized test sample in 100 µl of the coupling buffer, and then dry in a vacuum centrifuge to remove any hydrochloride if a protein hydrolysis step was used. dissolve the test sample in 100 µl of coupling buffer, add 5 µl of pitc, and incubate at room temperature for 5 minutes. the test sample is again dried in a vacuum centrifuge, and is dissolved in 250 µl of sample solvent.
chromatographic system the liquid chromatograph is equipped with a 254-nm detector and a 4.6-mm × 250-mm column that contains 5-µm packing l1. the flow rate is about 1 ml per minute, and the column temperature is maintained at 52 . the system is programmed as follows. the column is equilibrated with solution a; over the next 15 minutes, the composition of the mobile phase is changed linearly to 85% solution a and 15% solution b; over the next 15 minutes, the composition is changed linearly to 50% solution a and 50% solution b; then there is a step change to 100% solution c, and this is held for 10 minutes; then there is a step change to 100% solution a, and the column is allowed to equilibrate before the next injection.
procedure inject about 1.0 nmol of each pitc-amino acid under test (10-µl sample in sample solvent) into the chromatograph, and proceed as directed for chromatographic system.
precolumn derivatization of amino acids with 6-aminoquinolyl-n-hydroxysuccinimidyl carbamate (aqc) followed by reverse-phase hplc separation with fluorometric detection is used.
aqc reacts with amino acids to form stable, fluorescent unsymmetric urea derivatives (aqc-amino acids) which are readily amenable to analysis by reverse-phase hplc. therefore, precolumn derivatization of amino acids with aqc followed by reverse-phase hplc separation is used to analyze the amino acid composition.
separation of the aqc-amino acids on an ods column is accomplished through a combination of changes in the concentrations of acetonitrile and salt. selective fluorescence detection of the derivatives with an excitation wavelength at 250 nm and an emission wavelength at 395 nm allows for the direct injection of the reaction mixture with no significant interference from the only major fluorescent reagent byproduct, 6-aminoquinoline. excess reagent is rapidly hydrolyzed (t1/2< 15 seconds) to yield 6-aminoquinoline-n-hydroxysuccinimide and carbon dioxide, and after 1 minute no further derivatization can take place.
peak areas for aqc-amino acids are essentially unchanged for at least 1 week at room temperature, and the derivatives have more than sufficient stability to allow for overnight automated chromatographic analysis.
the detection limit is considered to be ranging from about 40 fmol to 320 fmol for each amino acid, except for cys. the detection limit for cys is approximately 800 fmol. response linearity is obtained in the range of 2.5 µm to 200 µm with correlation coefficients exceeding 0.999. good compositional data can be obtained from the analysis of derivatized protein hydrolysates containing as little as 30 ng of protein/peptide.
one method of precolumn aqc derivatization is shown below.
solution a prepare a solution having a composition of 140 mm sodium acetate and 17 mm triethylamine, and adjust with phosphoric acid to a ph of 5.02.
solution b: a mixture of acetonitrile and water (60:40).
sample derivatization procedure dissolve about 2 µg of the test sample in 20 µl of 15 mm hydrochloric acid, and dilute with 0.2 m borate buffer (ph 8.8) to 80 µl. the derivatization is initiated by the addition of 20 µl of 10 mm aqc in acetonitrile, and allowed to proceed for 10 minutes at room temperature.
chromatographic system the liquid chromatograph is equipped with a fluorometric detector set at an excitation wavelength of 250 nm and an emission wavelength of 395 nm and a 3.9-mm × 150-mm column that contains 4-µm packing l1. the flow rate is about 1 ml per minute, and the column temperature is maintained at 37 . the system is programmed as follows. the column is equilibrated with solution a; over the next 0.5 minute, the composition of the mobile phase is changed linearly to 98% solution a and 2% solution b; then over the next 14.5 minutes to 93% solution a and 7% solution b; then over the next 4 minutes to 87% solution a and 13% solution b; over the next 14 minutes to 68% solution a and 32% solution b; then there is a step change to 100% solution b for a 5-minute wash; over the next 10 minutes, there is a step change to 100% solution a; and the column is allowed to equilibrate before the next injection.
procedure inject about 0.05 nmol of each aqc-amino acid under test into the chromatograph, and proceed as directed for chromatographic system.
precolumn derivatization of amino acids with opa followed by reverse-phase hplc separation with fluorometric detection is used. this technique does not detect amino acids that exist as secondary amines (e.g., proline).
opa in conjunction with a thiol reagent reacts with primary amine groups to form highly fluorescent isoindole products. 2-mercaptoethanol and 3-mercaptopropionic acid can be used as thiol. opa itself does not fluoresce and consequently produces no interfering peaks. in addition, its solubility and stability in aqueous solution, along with the rapid kinetics for the reactions, make it amenable to automated derivatization and analysis using an autosampler to mix the sample with the reagent. however, lack of reactivity with secondary amino acids has been a predominant drawback. this method does not detect amino acids that exist as secondary amines (e.g., proline). to compensate for this drawback, this technique may be combined with another technique described in method 7 or method 8.
precolumn derivatization of amino acids with opa is followed by reverse-phase hplc separation. because of the instability of the opa-amino acid derivative, hplc separation and analysis are performed immediately following derivatization. the liquid chromatograph is equipped with a fluorometric detector for the detection of derivatized amino acids. fluorescence intensity of the opa-derivatized amino acids are monitored with an excitation wavelength of 348 nm and an emission wavelength of 450 nm.
the detection limits as low as 50 fmol via fluorescence have been reported, although the practical limit of analysis remains at 1 pmol. one method of precolumn opa derivatization is shown below.
solution a: a mixture of 100 mm sodium acetate (ph 7.2), methanol, and tetrahydrofuran (900:95:5).
chromatographic system the liquid chromatograph is equipped with a fluorometric detector set at an excitation wavelength of 348 nm and an emission wavelength of 450 nm and a 4.6-mm × 75-mm column that contains 3-µm packing l3. the flow rate is about 1.7 ml per minute, and the column temperature is maintained at 37 . the system is programmed as follows. the column is equilibrated with 92% solution a and 8% solution b; over the next 2 minutes, the composition of the mobile phase is changed to 83% solution a and 17% solution b, and held for an additional 3 minutes; then changed to 54% solution a and 46% solution b over the next 5 minutes, and held for an additional 2 minutes; then changed to 34% solution a and 66% solution b over the next 2 minutes, and held for 1 minute; then over the next 0.3 minute changed to 20% solution a and 80% solution b, and held for an additional 2.6 minutes; and then finally over 0.6 minute changed to 92% solution a and 8% solution b, and held for an additional 0.6 minute.
procedure inject about 0.02 nmol of each opa-amino acid under test into the chromatograph, and proceed as directed for chromatographic system.
precolumn derivatization of amino acids with (dimethylamino)azobenzenesulfonyl chloride (dabs-cl) followed by reverse-phase hplc separation with visible light detection is used.
dabs-cl is a chromophoric reagent employed for the labeling of amino acids. amino acids labeled with dabs-cl (dabs-amino acids) are highly stable and show the maximum absorption at 436 nm.
dabs-amino acids, all 19 naturally occurring amino acids derivatives, can be separated on an ods column of a reverse-phase hplc by employing gradient systems consisting of acetonitrile and aqueous buffer mixture. separated dabs-amino acids eluted from the column are detected at 436 nm in the visible region.
this method can analyze the imino acids, such as proline, together with the amino acids, at the same degree of sensitivity. dabs-cl derivatization method permits the simultaneous quantification of tryptophan residues by previous hydrolysis of the protein/peptide with sulfonic acids, such as mercaptoethanesulfonic acid, p-toluenesulfonic acid, or methanesulfonic acid, described for method 2 in protein hydrolysis under amino acid analysis. the other acid-labile residues, asparagine and glutamine, can also be analyzed by previous conversion into diaminopropionic acid and diaminobutyric acid, respectively, by treatment of protein/peptide with bti, described for method 11 in protein hydrolysis under amino acid analysis.
the nonproteinogenic amino acid, norleucine, cannot be used as an internal standard in this method as this compound is eluted in a chromatographic region crowded with peaks of primary amino acids. nitrotyrosine can be used as an internal standard because it is eluted in a clean region.
the detection limit of dabs-amino acid is about 1 pmol. as little as 2 to 5 pmol of an individual dabs-amino acid can be quantitatively analyzed with reliability, and only 10 ng to 30 ng of the dabsylated protein hydrolysate is required for each analysis.
one method for precolumn dabs-cl derivatization is shown below.
solution a: 25 mm sodium acetate (ph 6.5) containing 4% of dimethylformamide.
sample buffer: 50 mm sodium bicarbonate, adjusted to a ph of 8.1.
sample dilution buffer prepare a mixture of 50 mm sodium phosphate (ph 7.0) and alcohol (1:1).
sample derivatization procedure dissolve the test sample in 20 µl of sample buffer, add 40 µl of derivatization reagent, and mix. the sample container is sealed with a silicon-rubber stopper, and heated to 70 for 10 minutes. during the sample heating, the mixture will become completely soluble. after the derivatization, dilute the test sample with an appropriate quantity of the sample dilution buffer.
chromatographic system the liquid chromatograph is equipped with a 436-nm detector and a 4.6-mm × 250-mm column that contains packing l1. the flow rate is about 1 ml per minute, and the column temperature is maintained at 40 . the system is programmed as follows. the column is equilibrated with 85% solution a and 15% solution b; over the next 20 minutes, the composition of the mobile phase is changed to 60% solution a and 40% solution b; over the next 12 minutes, the composition is changed to 30% solution a and 70% solution b, and held for an additional 2 minutes.
procedure inject about 0.05 nmol of the dabs-amino acids into the chromatograph, and proceed as directed for chromatographic system.
precolumn derivatization of amino acids with 9-fluorenylmethyl chloroformate (fmoc-cl) followed by reverse-phase hplc separation with fluorometric detection is used.
fmoc-cl reacts with both primary and secondary amino acids to form highly fluorescent products. the reaction of fmoc-cl with amino acid proceeds under mild conditions, in aqueous solution, and is completed in 30 seconds. the derivatives are stable, with only the histidine derivative showing any breakdown. although fmoc-cl is fluorescent itself, the reagent excess and fluorescent side-products can be eliminated without loss of fmoc-amino acids.
fmoc-amino acids are separated by reverse-phase hplc using an ods column. the separation is carried out by gradient elution varied linearly from a mixture of acetic acid buffer, methanol, and acetonitrile (50:40:10) to a mixture of acetonitrile and acetic acid buffer (50:50), and 20 amino acid derivatives that are separated in 20 minutes. each derivative eluted from the column is monitored by a fluorometric detector set at an excitation wavelength of 260 nm and an emission wavelength of 313 nm.
the detection limit is in the low fmol range. a linearity range of 0.1 µm to 50 µm is obtained for most amino acids.
one method for precolumn fmoc-cl derivatization is shown below.
acetic acid buffer transfer 3 ml of glacial acetic acid and 1 ml of triethylamine to a 1-l volumetric flask, and dilute with hplc grade water to volume. adjust with sodium hydroxide to a ph of 4.20.
solution a: a mixture of acetic acid buffer, methanol, and acetonitrile (50:40:10).
solution b: a mixture of acetonitrile and acetic acid buffer (50:50).
borate buffer prepare a 1 m boric acid solution, and adjust with sodium hydroxide to a ph of 6.2.
fmoc-cl reagent dissolve 155 mg of 9-fluorenylmethyl chloroformate in 40 ml of acetone, and mix.
sample derivatization procedure to 0.4 ml of the test sample add 0.1 ml of borate buffer and 0.5 ml of fmoc-cl reagent. after about 40 seconds, extract the mixture with 2 ml of pentane, and then extract again with fresh pentane. the aqueous solution with amino acid derivatives is then ready for injection.
chromatographic system the liquid chromatograph is equipped with a fluorometric detector set at an excitation wavelength of 260 nm and an emission wavelength of 313 nm and a 4.6-mm × 125-mm column that contains 3-µm packing l1. the flow rate is about 1.3 ml per minute. the system is programmed as follows. the column is equilibrated with solution a, and this composition is maintained for 3 minutes; over the next 9 minutes, it is changed to 100% solution b; then over the next 0.5 minute, the flow rate is increased to 2 ml per minute, and held until the final fmoc-amino acid is eluted from the column. the total run time is about 20 minutes.
procedure inject not less than 0.01 nmol of each fmoc-amino acid under test into the chromatograph, and proceed as directed for chromatographic system. the fmoc-histidine derivative will generally give a lower response than the other derivatives.
precolumn derivatization of amino acids with 7-fluoro-4-nitrobenzo-2-oxa-1,3-diazole (nbd-f) followed by reverse-phase hplc separation with fluorometric detection is used.
7-fluoro-4-nitrobenzo-2-oxa-1,3-diazole (nbd-f) reacts with both primary and secondary amino acids to form highly fluorescent products. amino acids are derivatized with nbd-f by heating to 60 for 5 minutes.
nbd-amino acid derivatives are separated on an ods column of reverse-phase hplc by employing a gradient elution system consisting of acetonitrile and aqueous buffer mixture, and 17 amino acid derivatives that are separated in 35 minutes. e-aminocaproic acid can be used as an internal standard because it is eluted in a clean chromatographic region. each derivative eluted from the column is monitored by a fluorometric detector set at an excitation wavelength of 480 nm and an emission wavelength of 530 nm.
the sensitivity of this method is almost the same as that for the precolumn opa derivatization method (method 5), excluding proline to which opa is not reactive and might be advantageous for nbd-f against opa.
the detection limit for each amino acid is about 10 fmol. profile analysis was achieved for about 1.5 mg of protein hydrolysates in the final precolumn labeling reaction mixture for hplc.
one method for precolumn nbd-f derivatization is shown below.
solution a: a solution of 10mm sodium citrate containing 75 mm sodium perchlorate, adjusted with hydrochloric acid to a ph of 6.2.
solution b: a mixture of acetonitrile and water (50:50).
sample buffer: a 0.1 m boric acid solution, adjusted with sodium hydroxide to a ph of 9.2.
derivatization reagent dissolve 5 mg of nbd-f in 1.0 ml of alcohol, and mix.
sample derivatization procedure dissolve the test sample in 20 µl of sample buffer, add 10 µl of derivatization reagent, and mix. the sample container is heated at 60 for 5 minutes. after the derivatization, dilute the test sample with 300 µl of solution a.
chromatographic system the liquid chromatograph is equipped with a fluorometric detector set at an excitation wavelength of 480 nm and an emission wavelength of 530 nm and a 4.6-mm × 150-mm column that contains 5-µm particle size ods silica packing. the flow rate is about 1.0 ml per minute, and the column temperature is maintained at 40 . the system is programmed as follows. the column is equilibrated with 94% solution a and 6% solution b; over the next 16 minutes, the composition is changed linearly to 63% solution a and 37% solution b; over the next 5 minutes, the composition is changed linearly to 62% solution a and 38% solution b; over the next 9 minutes, the composition is changed linearly to 100% solution b, and held for an additional 5 minutes; then finally over 2 minutes, the composition is changed linearly to 94% solution a and 6% solution b; and then the column is allowed to equilibrate before the next injection.
procedure inject about 15 pmol of each nbd-amino acid under test into the chromatograph, and proceed as directed for chromatographic system.
when determining the amino acid content of a protein/peptide hydrolysate, it should be noted that the acid hydrolysis step destroys tryptophan and cysteine. serine and threonine are partially destroyed by acid hydrolysis, while isoleucine and valine residues may be only partially cleaved. methionine can undergo oxidation during acid hydrolysis, and some amino acids (e.g., glycine and serine) are common contaminants. application of adequate vacuum (less than 200 µm of mercury or 26.7 pa) or introduction of inert gas (argon) in the headspace of the reaction vessel during vapor phase hydrolysis can reduce the level of oxidative destruction. therefore, the quantitative results obtained for cysteine, tryptophan, threonine, isoleucine, valine, methionine, glycine, and serine from a protein/peptide hydrolysate may be variable and may warrant further investigation and consideration.
in which ru is the peak response, in nmol, of the amino acid under test; and r is the sum of peak responses, in nmol, for all amino acids present in the test sample. comparison of the mole percent of the amino acids under test to data from known proteins can help establish or corroborate the identity of the sample protein.
in which m is the recovered quantity, in nmol, of the amino acid under test; m is the total mass, in µg, of the protein; and mwt is the molecular weight, in mg, of the unknown protein.
known protein samples this data analysis technique can be used to investigate the amino acid composition and protein concentration of a protein sample of known molecular weight and amino acid composition using the amino acid analysis data. when the composition of the protein being analyzed is known, one can exploit the fact that some amino acids are recovered well, while other amino acid recoveries may be compromised because of complete or partial destruction (e.g., tryptophan, cysteine, threonine, serine, methionine), incomplete bond cleavage (i.e., for isoleucine and valine), and free amino acid contamination (i.e., by glycine and serine).
because those amino acids that are recovered best represent the protein, these amino acids are chosen to quantify the amount of protein. well-recovered amino acids are, typically, aspartate-asparagine, glutamate-glutamine, alanine, leucine, phenylalanine, lysine, and arginine. this list can be modified based on experience with one's own analysis system. divide the quantity, in nmol, of each of the well-recovered amino acids by the expected number of residues for that amino acid to obtain the protein content based on each well-recovered amino acid. average the protein content results calculated. the protein content determined for each of the well-recovered amino acids should be evenly distributed about the mean. discard protein content values for those amino acids that have an unacceptable deviation from the mean. typically, a greater than 5% variation from the mean is considered unacceptable, but this is arbitrary. recalculate the mean protein content from the remaining values to obtain the protein content of the sample. divide the content of each amino acid by the calculated mean protein content to determine the amino acid composition of the sample by analysis.
in which m is the experimentally determined quantity, in nmol per amino acid residue, of the amino acid under test; and ms is the known residue value for that amino acid. the average relative compositional error is the average of the absolute values of the relative compositional errors of the individual amino acids, typically excluding tryptophan and cysteine from this calculation. the average relative compositional error can provide important information on the stability of analysis run over time. the agreement in the amino acid composition between the protein sample and the known composition can be used to corroborate the identity and purity of the protein in the sample.

arcelormittal south africa (amsa) announced steel price increases of up to 11% – more than double inflation – in an effort to keep its vanderbijlpark works afloat – a steelmaking facility that is currently losing r300m a month.
themba nkosi, gm of amsa’s human resources, corporate communications and stakeholder affairs, said today the vanderbijlpark works was of critical importance but it continued to face cost pressures including the recently announced 9.4% increase in electricity costs.
there had been also been an increase in the cost of iron ore following a 14% increase over the last month of the mineral (but down just below 5% year-on-year) owing to restocking of steel in china.
“the challenges faced by arcelormittal south africa and the local steel industry are still persisting, and they are putting the company and the steel sector in a difficult position,” said nkosi in a statement.
“creating a sustainable and profitable business is critically important for the stability of south africa’s ongoing steel needs and requirements,” he said.
amsa said in august last year that it would cut 400 jobs following a restructuring of its vereeniging works and said a review of operations had been extended to vanderbijlpark.
the south african government had agreed to provide some import duty protection against chinese imports whilst sishen iron ore company, a subsidiary of kumba iron ore, had also agreed to lower its iron ore sales price to amsa.
however, the company remained in dire straits.
amsa shareholders suffered an r8.5bn loss in the year to december from a r158m loss in 2014. it posted r4.25bn in impairments for the year after a year of heavy restructuring. the company completed a r4.5bn rights offer to get back on its feet, largely under-written by luxembourg-based parent company, arcelormittal.
the outcome is that amsa’s hot rolled coil product will be increased 9% on average from april while plate ad cold rolled steel will increase 11% on average.
long products used in construction, such as reinforcing bar would be increased 8% whilst light sections which are used for fencing and windows would increase on average only 2% from april.
nkosi said steel prices had been increasing this year but that the company had kept its increases in line with fair pricing procedures as agreed with the south african government. meanwhile, the government’s promise to impose duties on cheap imports had not yet taken effect.
quite whether the price increases fully reflect global trading conditions remains to be seen.
there had been a recent kick up in steel prices globally – which was behind the spike in iron ore prices – but this was unlikely to be sustained, according to goldman sachs.
“the strong spot margin for china steel had been a major reason for the improvement in sentiment around the iron ore market with the potential for more demand from steel mills in a positive pricing environment a major part of the bull case,” it said in a note to clients.
“the sharp retracement suggests that end demand is not sufficiently high to justify prices at this level,” it added.

suction cleaners plug into your skimmer or dedicated vacuum line and are powered from the suction of your pool pump. the downside of these cleaners is that pool pump has to be running for this bad boy to work. you’ll also notice that the suction pool cleaner’s throat is relatively small compared to the other cleaners. suction pool cleaners are designed more for dirt and small debris and not for large leaves, large debris. these cleaners are ideal for screened-in pools and pools where you don’t get a lot of leaves.
pressure cleaners typically work off a booster pump; these are secondary pumps to your main pool pump, and its purpose is to provide the cleaner its propulsion and “suction.” pressure cleaners work by pushing through this hose, and through these nozzles at the bottom of the cleaner. the nozzles push the water up away from the pool floor, creating a turbulence vacuum called a venture effect. debris is pulled off the pool floor and gathered into the debris bag.
the pressure cleaner’s throat is noticeably wider which makes these cleaners great for pools that burdened with heavy debris that suction cleaners are too small to handle.
manufacturers make models like this poolvergneugen 4 wheel pressure cleaner where you don’t need a booster pump. these pressure-side cleaners use your main pool pump, but you have to remove one of your return jets and plug the hose into the return jet.
this is a robotic pool cleaner, and it is different than the suction and pressure side cleaner because it does not use a pump at all. these are much more economical to run than any other style of pool cleaner because you don’t have to run your pool pump which draws a lot more amps than this does. this plug goes a normal wall receptacle, from the outlet it goes into a power supply which is a transformer, that drops the 120v down to 24v or 12v which makes it safe for the pool. the safe voltage level runs through a waterproof cable into the cleaner.
robotic pool cleaners normally have a three to five-hour cleaning cycle, it’s a lot easier. a pool owner doesn’t don’t have to babysit this cleaner, you just drop it in the pool and go on about your business. also, at the bottom of this, you can see the cleaning vents or the suction vents. they are pretty wide so that you should be able to get most big debris. big debris, small debris, sycamore leaves.
these also close once the cleaners turn off, so leaves don’t back-flush back into your pool. robotic cleaners have a bag or a cartridge element to filter the water of debris. cartridge based cleaners are best for catching fine particles like sand. they’re very versatile, and i love them.
tell me more about your robotic pool cleaners. the one i have now is no longer doing a good job on my 20′ x 40′ pool. it cleans only one part of the pool and ignores the rest. how much does your robotic pool cleaner cost?
hello, douglas. we carry residential robotic pool cleaners that range from the inexpensive aquabot turbo t-jet all the way up to the hayward aquavac tigershark and each one has its pros and cons.
the main things you want to focus on, is what do you need your cleaner to do, and what is your price range? some robotic pool cleaners clean both the floor and the wall, while some can only clean the floor. the floor cleaners are generally less expensive, but it means you will have to manually scrub your pool walls when necessary. my perosnal suggestion is to start with the brands of aquabot and dolphin/maytronics, because they specialize in pool cleaning. the two companies put all their energy into making the best pool cleaners in the industry and they are pretty darn good at it.

japan is showcasing its best innovative developments at the expo 2017. the country is one of the global leaders in use of alternative energy. a fascinating tour in the japanese expo pavilion allows the visitors to understand why.
acquaintance with japan begins right on the street where staff members welcome the visitors to the pavilion. the staff gives a brief presentation at the entrance. japanese pavilion spokesperson, kenichi kojima speaks in russian and english fluently. he has begun learning the kazakh language as well.
- in 2005, my hometown aichi hosted an exhibition. then, i was very interested in the expo and i set out to work at a large-scale event in the future. when i was studying at the university, i learned that your country will host an exhibition and its main topic will be the development of green technologies. so i immediately decided to come to kazakhstan. it is a great honor for me to work here and to take part in such an event which is useful for the future of the planet.
the japanese pavilion is divided into three sections and every section has its own concept. japanese philosophical approach to high technologies is reflected here where the visitors are first introduced to the history of alternative energy. japan’s transition to green energy is not a trend of fashion and a desire to be on the top of rankings, but it is a necessity since there are practically no minerals in the country’s territory. this is why japan with minimal natural resources has developed its own environmentally friendly way of generating electricity.
- the 1973 oil crisis forced us to introduce a new strategy to change from energy-intensive to high-tech economy in japan. we decided to replace the mineral resources with intellectual ones. this primarily concerned the transfer of electricity and industrial production from liquid fuel to other carriers. the targets were acceleration of development of nuclear power, increase of coal and liquefied natural gas imports.
in the next section, visitors can see firsthand japan’s ambitious projects in the field of green technologies. the authors didn’t limit themselves with a film; they also created a mobile application for better visual and tactile effects. the visitors can truly feel themselves in a technological future. the film talks about the country's plans such as launching an aircraft on biofuel. they claim that this will become a reality by 2020. japanese scientists invented fuel from dried seaweed powder. according to its chemical properties, it is similar to kerosene. the plant which produces green fuel with a capacity of up to 5 barrels a day is built for convenience and located not far from japan’s two largest airports.
- our developments are primarily aimed at minimizing the consequences of harmful emissions into the atmosphere. we want to launch planes on biofuels, not because of financial considerations, but because we are worried about the future of our planet. we think that all countries should follow this example. today, it is necessary to start reducing carbon dioxide emissions.
the third section of the japanese pavilion is perhaps the most fascinating one. guests can play interactive games here. visitors can contribute to the development of green energy and try to reduce the amount of carbon dioxide emissions. it is collected in special baskets and then sent to the plant where it generates energy. all the technological solutions in the pavilion are so easily accessible and creative that even children can understand and have an interest in them. the innovative development of the japanese company, toshiba is presented here, too. this is a special container where it is possible to store clean energy. as experts say, to get clean energy from alternative sources is only half of the matter since the most difficult in this process is to be able to preserve the energy.
- it is a generator of solar energy which means that the generator has solar panels. it also has battery panels which means that the energy is received from solar batteries where the energy accumulates. there is a system for electrolysis, too.
in addition to the new developments which are going to make a breakthrough in the development of renewable energy, the japanese pavilion also includes the innovations that have already proven themselves around the world. these are energy-saving led lamps. in the 1990s, japanese scientists invented a blue led which turned out to be cheap in production. for this discovery, the scientists were awarded the nobel prize in physics. the technology of home energy management system is also presented in the pavilion. in japan, people equip their houses with solar batteries, mini power stations, high-tech refrigerators and air conditioners with built-in sensors. this kind of an ergonomic lifestyle is reflected everywhere. the state has even adopted a law on the rational use of energy. the japanese model of energy consumption is primarily created for the population’s convenience. the country is ready to share its technologies as well as to promote joint projects with kazakhstan. undoubtedly, the exhibition will give a new impetus to the development of multilateral partnerships in the field of green technologies.

in recognition of great britain's ranked most energy efficient of world's largest economies by american council for an energy-efficient economy (aceee), enms-doc submitted an article to "kankyo business"(japan business publishing co., ltd.) about what we saw at the opening ceremonies of the london 2012 summer olympic games.
no one will deny one of the factors, which caused the industrial revolution to take place from 1760s to 1830s in britain, was the strong development of globalisation through the trade policy. however dr. robert c. allen, professor of economic history at oxford university, in his column (http://www.voxeu.org/article/why-was-industrial-revolution-british/) introducing his book "the british industrial revolution in global perspective" pointed out the factor of the low energy cost situation due to the exploitation of coal. in spite of britain's globalisation approach, the industiral revolution in the other countries were not as effective due to economical situations. in other words they face the barrier of having a higher energy cost.
enms-doc is coordinating the mission, organised by japan business publishing co., ltd. and the graduate school of project design, is seeking companies willing to do business in japan with partnership arrangement in the field of sustainability, and willing to take advantage of this mission coming to london area.
japan is struggling to identify what will be the next step in the field of sustainability. one reason is that there is no direct japanese translation of the word "sustainability". the other is in terms of the business related to energy management, japan needs to make more effort to harmonise with the rest of the world.
as a first step to counter these issues, "japanese sustainability business discovery mission to the u.k." was organised supported by ukti japan/british embassy tokyo seeking potential partners willing to do business in japan with their new ideas, technology, products, services, etc. in the field of sustainability.
it will be approximately 20-company mission, leaders in sustainability business in japan with diverse range of business types such as energy solution provider, it implementer, building facility management, it and control company, bems-aggregator player , esco player, etc., aiming to get acquaintance with companies interested to explore business in japan. our immediate aim is together with ukti to identify business units interested to explore japanese market by forming partnership with japanese companies pursuing sustainability business development.
any individual or company considering this mission as an opportunity, how about a rendezvous.
there will be several options to meet the mission however the major event will be the "sustainability day" at the university of london on monday 5th november, an open forum aiming for the mission members to meet and exchange ideas with partner potentials. kindly please contact us if you are interested or your recommendations to identify companies who may wish to meet the mission. "meet the mission invitation package" for download.
the "bems-aggregator", a 30 billion yen (gbp 240 million) project, is to ensure better energy performing 20,000 small/medium buildings (less than 500kw contract) and 10,000 model homes by promoting installation of bems (hems for homes) and to appoint aggregators to measure the improvement on behalf of meti.
there are 23 designated "bems-aggregator" companies, and with their consortium partners, there are 77 player companies (download list of aggregators and consortium companies). the project has officially started on 17 april this year. for the intended delegation, the members will be most likely from those 77 companies.
please contact nobby yamanouchi (nobby@enms-doc.com) if you have any further question.
we are organizing together with our enms partner in malaysia, eesolution engineering view company profile page , a 3-day workshop to make the participating organisation to become competent to self-declare iso 50001.
to gain knowledge of how to measure and quantitatively verify the saving results using proven regression analysis tool.
participants gaining competency level to lead their organisation to implement enms operation good enough to self-declare iso 50001, international energy management standard.
organisation when they return from the 3-day sessions.

snowy hydro limited operates in australia’s southern alps. it provides renewable energy and energy-related products & manages critical water flows. it is also involved in implementing a range of community initiatives.
as the organisation emerged from a semi-government business, it needed to shed its ‘silo thinking’ and embrace a culture of innovation where proactive behaviour was encouraged.
although senior leaders had a clear vision of the organisation, the larger workforce of 400 employees did not share or have a sound understanding of the direction of the business.
a 360 ‘inside-out’ approach was taken, guiding individuals across the entire organisation through a process of personal mastery and goal alignment & then using this as a basis to apply similar principles to their own leadership and organisational development (leadership mastery).
financial performance: 8% year-on-year growth in earnings.
safety: lost time injuries reduced from 22 per year to 0.5 per year.
cultural improvement: 42% improvement in cultural index.
industrial relations: zero days lost to industrial relations issues over 10 years.
environmental factors: neither performance nor environment impacted by 1-in-500 year fire, 1-in-500 year drought and 1-in-500 year water inflow.
