The Triassic was generally dry, a trend that began in the late Carboniferous, and highly seasonal, especially in the interior of Pangaea. Low sea levels may have also exacerbated temperature extremes. With its high specific heat capacity, water acts as a temperature-stabilizing heat reservoir, and land areas near large bodies of water—especially oceans—experience less variation in temperature. Because much of Pangaea's land was distant from its shores, temperatures fluctuated greatly, and the interior probably included expansive deserts. Abundant red beds and evaporites such as halite support these conclusions, but some evidence suggests the generally dry climate of was punctuated by episodes of increased rainfall. The most important humid episodes were the Carnian Pluvial Event and one in the Rhaetian, a few million years before the Triassic–Jurassic extinction event.

In peacetime, the class was occasionally used on fast freights from Southampton Docks, although it was common to see them at the head of freight and troop trains during the Second World War. Ten "Urie Arthurs" were transferred to the London and North Eastern Railway (LNER) in October 1942, and were based at Heaton shed for use on freight and occasional passenger trains in the north east and southern Scotland. They returned to the Southern Railway in July 1943 after the introduction of United States Army Transportation Corps S160 class 2-8-0s into service. From 1945 the King Arthur class regularly deputised for Bulleid's new Pacifics, which were experiencing poor serviceability due to mechanical failures. The entire class came into British Railways ownership in 1948: they could be found in most areas of the Southern Region on medium-length expresses and stopping trains on the ex-LSWR mainline.

Many historians of technology consider that true machine tools were born when the toolpath first became guided by the machine itself in some way, at least to some extent, so that direct, freehand human guidance of the toolpath (with hands, feet, or mouth) was no longer the only guidance used in the cutting or forming process. In this view of the definition, the term, arising at a time when all tools up till then had been hand tools, simply provided a label for "tools that were machines instead of hand tools". Early lathes, those prior to the late medieval period, and modern woodworking lathes and potter's wheels may or may not fall under this definition, depending on how one views the headstock spindle itself; but the earliest historical records of a lathe with direct mechanical control "of the cutting tool's path" are of a screw-cutting lathe dating to about 1483. This lathe "produced screw threads out of wood and employed a true compound slide rest".

Certain medications, particularly contraceptive medications, can induce amenorrhoea in a healthy woman. The lack of menstruation usually begins shortly after beginning the medication and can take up to a year to resume after stopping its use. Hormonal contraceptives that contain only progestogen, like the oral contraceptive Micronor, and especially higher-dose formulations, such as the injectable Depo-Provera, commonly induce this side effect. Extended cycle use of combined hormonal contraceptives also allow suppression of menstruation. Patients who stop using combined oral contraceptive pills (COCP) may experience secondary amenorrhoea as a withdrawal symptom. The link is not well understood, as studies have found no difference in hormone levels between women who develop amenorrhoea as a withdrawal symptom following the cessation of COCP use and women who experience secondary amenorrhoea because of other reasons. New contraceptive pills which do not have the normal seven days of placebo pills in each cycle, have been shown to increase rates of amenorrhoea in women. Studies show that women are most likely to experience amenorrhoea after one year of treatment with continuous OCP use.

The 704 at that time was thus regarded as "pretty much the only computer that could handle complex math". The 704 was a significant improvement over the earlier IBM 701 in terms of architecture and implementation. Like the 701, the 704 uses vacuum-tube logic circuitry, but increased the instruction size from 18-bit to 36-bit, the same as the memory's word size. Changes from the 701 include the use of magnetic-core memory instead of Williams tubes, floating-point arithmetic instructions, 15-bit addressing and the addition of three index registers. To support these new features, the instructions were expanded to use the full 36-bit word. The new instruction set, which is not compatible with the 701, became the base for the "scientific architecture" subclass of the IBM 700/7000 series computers.

There are substantial concerns over the conservation status of "Utricularia resupinata" throughout its geographical distribution, with the following list offered by the US Department of Agriculture’s source on “Threatened and Endangered Information:” “Of Special Concern” are Rhode Island and Tennessee; listed as “Threatened” are Massachusetts and Vermont; “Endangered” include Connecticut, Maine, Maryland, and New Jersey; and labeled as “Extirpated” are Indiana and Pennsylvania, with a recent discovery of a species community in the former. Three reasons are offered for this species being of special concern, threatened, endangered, or extirpated—heavy recreational use of waterways; high nutrient levels from lawn fertilizers or faulty septic systems; and competition from native or non-native invasive species. A conservation plan is needed for the protection and proliferation of this delicate but important species which so fascinated Frank Tweedy, Mary Treat, Charles Darwin, and generations of botanists and biologists.

Chondrites also contain refractory inclusions (including Ca–Al inclusions), which are among the oldest objects to form in the Solar System, particles rich in metallic Fe-Ni and sulfides, and isolated grains of silicate minerals. The remainder of chondrites consists of fine-grained (micrometre-sized or smaller) dust, which may either be present as the matrix of the rock or may form rims or mantles around individual chondrules and refractory inclusions. Embedded in this dust are presolar grains, which predate the formation of our solar system and originated elsewhere in the galaxy. The chondrules have distinct texture, composition and mineralogy, and their origin continues to be the object of some debate. The scientific community generally accepts that these spheres were formed by the action of a shock wave that passed through the Solar System, although there is little agreement as to the cause of this shock wave.

After the Dieter Sattler and his minister, Alois Hundhammer were both replaced in the government. This may in part have been connected with the fact that Sattler had served as what amounted to an "under-minister" despite never actually having been elected a member of the Bavarian regional parliament (""Landtag""), or it may simply have reflected the shifting power balance within the party. Between 1950 and 1952 Sattler served as president of the German Theatre Association (""Deutscher Bühnenverein""). He also served during 1951/52 as chair of the broadcasting council at Bayerischer Rundfunk, the Bavarian broadcasting company. By this time, following the dramatic events in and above Berlin during 1948/49, Germany's American, British and French military occupation zones (but, conspicuously, not the Soviet occupation zone) had been combined in May 1949 and relaunched as the US-sponsored German Federal Republic (West Germany).

There were many precursors to this transdisciplinarity of "people, place, and technology." From an architecture, planning and design background, there is the work of the late William J. Mitchell, Dean of the MIT School of Architecture and Planning, and author of the 1995 book "City of Bits: Space, Place, and the Infobahn". Mitchell was influential in suggesting a profound relationship between place and technology at a time when mainstream interest was focused on the promise of the Information Superhighway and what Frances Cairncross called the "Death of Distance". Rather than a decline in the significance of place through remote work, distance education, and e-commerce, the physical / tangible layers of the city started to mix with the digital layers of the internet and online communications. Aspects of this trend have been studied under the terms community informatics and community networks.

In 1926, pioneering accelerator physicists Merle Tuve and Gregory Breit built a 5 million volt Tesla coil as a linear particle accelerator. The bipolar coil consisted of a pyrex tube a meter long wound with 8000 turns of fine wire, with round corona caps on each end, and a 5 turn spiral primary coil surrounding it at the center. It was operated in a tank of insulating oil pressurized to 500 psi which allowed it to reach a potential of 5.2 megavolts. Although it was used for a short period in 1929-30 it was not a success because the particles' acceleration had to be completed within the brief period of a half cycle of the RF voltage.

R. H. Inglis Palgrave's "Dictionary of Political Economy" (1894–1899), 3 v., was the forerunner of "The New Palgrave". The initial contractual agreement between Palgrave and the publisher Macmillan & Co. is dated 1888. Serial installments in 1891–92 had disappointing sales. An appendix was added to Volume III in 1908, so completing publication of the set. The "Dictionary" was wide-ranging and sometimes idiosyncratic. It included for example a comprehensive treatment of laws on property and commercial transactions. Professional reaction has been described as generally favorable and unsurprising, "given that almost all economists of any repute had already endorsed the enterprise by agreeing to contribute." Nearly thirty years after the first volume appeared, "Palgrave's Dictionary of Political Economy" (1923–1926), edited by Henry Higgs, appeared with Palgrave's name added to the title but few changes in structure or contents.

One of the next milestones came in 1904, when Helge von Koch, extending ideas of Poincaré and dissatisfied with Weierstrass's abstract and analytic definition, gave a more geometric definition including hand-drawn images of a similar function, which is now called the Koch snowflake. Another milestone came a decade later in 1915, when Wacław Sierpiński constructed his famous triangle then, one year later, his carpet. By 1918, two French mathematicians, Pierre Fatou and Gaston Julia, though working independently, arrived essentially simultaneously at results describing what is now seen as fractal behaviour associated with mapping complex numbers and iterative functions and leading to further ideas about attractors and repellors (i.e., points that attract or repel other points), which have become very important in the study of fractals.

The engine was also known to suffer from afterburner blowout on takeoff, or even non-ignition, resulting in a major loss of thrust that could be detected by the pilot—the recommended action was to abandon the takeoff. The first fatal accident in German service was caused by this phenomenon. Some pilots experienced uncommanded "stick kicker" activation at low altitudes while flying straight and level, so F-104 crews were often directed to deactivate it for flight operations. Asymmetric or "split" flap deployment was another frequent cause of accidents. Many pilots also experienced severe nose wheel "shimmy" on landing, which usually resulted in the aircraft leaving the runway and in some cases even flipping over onto its back.

Under the reign of Shah Jahan, the symbolic content of Mughal architecture reached a peak. The Taj Mahal complex was conceived as a replica on earth of the house of the departed in paradise (inspired by a verse by the imperial goldsmith and poet, Bibadal Khan). This theme, common in most Mughal funerary architecture, permeates the entire complex and informs the detailed design of all the elements. A number of secondary principles also inform the design, of which hierarchy is the most dominant. A deliberate interplay is established between the building's elements, its surface decoration, materials, geometric planning and its acoustics. This interplay extends from what can be experienced directly with the senses, into religious, intellectual, mathematical and poetic ideas. The constantly changing sunlight reflected from the Taj's translucent marble is not a happy accident, it had a deliberate metaphoric role associated with the presence of god as light.

The prime contractor, MEADS International, is a multinational joint venture headquartered in Orlando, Florida. Its participating companies are MBDA Italia, MBDA Deutschland GmbH, and Lockheed Martin. The company initially won a competitive downselect to develop the MEADS system in 1999, but the program could not be started because the losing competitor filed two successive suits. In 2001, a $216 million Risk Reduction Effort contract was awarded to incorporate a new interceptor approach. In May 2005, MEADS International signed a definitized contract valued at $2 billion plus €1.4 billion for MEADS design and development. This development contract was completed in 2014. The U.S. funded 58 percent of the MEADS Design and Development program, with European partners Germany and Italy providing 25 percent and 17 percent respectively.

Extensive modifications were required for the B-29 Superfortress to enable it to perform the special operations mission. All turrets, except the tail turret, were removed from the aircraft, leaving the aircraft unarmed and incapable of self-defense. A parachutist's exit was made where the belly gun turret was originally located. Resupply bundles were mounted on bomb racks inside the bomb bay, thus allowing the bundles to be dropped like bombs over the drop zone. Aircraft were painted black, and a crude HTR-13 obstruction-warning radar was installed to warn the crew of approaching terrain. The major flaw in the B-29 employed in the special operations role, however, was that it had been designed for high-altitude precision bombing, not low-level airdrop. Over the drop zone at drop airspeed, the aircraft was near its stall speed and was difficult to maneuver.

On 16 April 2011, India and Kazakhstan signed an inter-governmental agreement for Cooperation in Peaceful Uses of Atomic Energy, that envisages a legal framework for supply of fuel, construction and operation of atomic power plants, exploration and joint mining of uranium, exchange of scientific and research information, reactor safety mechanisms and use of radiation technologies for healthcare. PM Manmohan Singh visited Astana where a deal was signed. After the talks, the Kazakh President Nazarbaev announced that his country would supply India with 2100 tonnes of uranium and was ready to do more. Kazakhstan is the largest producer of uranium in the world. India and Kazakhstan already have civil nuclear cooperation since January 2009 when Nuclear Power Corporation of India Limited (NPCIL) and Kazakh nuclear company KazAtomProm signed an MoU during the visit of Nazarbaev to Delhi. Under the contract, KazAtomProm supplies uranium which is used by Indian reactors.

He was born at Newcastle-on-Tyne in or around 1734. At ten years of age he was placed in the care of an uncle at Durham, Thomas Walker (died 10 November 1763), successively minister at Cockermouth, 1732, Durham, 1736, and Mill Hill Chapel at Leeds, 1748. He attended the Durham School, by then "a north-country public school of repute and wide influence", under Richard Dongworth. In the autumn of 1749, being then about fifteen, he was admitted to the dissenting academy at Kendal under Caleb Rotherham; here he met his lifelong friend, John Manning (1730–1806). On Rotherham's retirement (1751) he was for a short time under Hugh Moises at Newcastle-on-Tyne. In November 1751 he entered at Edinburgh University with Manning, where he studied mathematics under Matthew Stewart. He moved to Glasgow in 1752 for the sake of the divinity lectures of William Leechman, continued his mathematical studies under Robert Simson, and heard the lectures of Adam Smith, but found their private conversation more instructive. Among his classmates were Newcome Cappe, Nicholas Clayton, and John Millar, members with him of a college debating society.

PFOA persists indefinitely in the environment. PFOA has been detected in the blood of many individuals of the general US population in the low and sub-parts per billion range, and levels are higher in chemical plant employees and surrounding subpopulations. PFOA and perfluorooctanesulfonic acid (PFOS) have been estimated to be in every American person’s blood stream in the parts per billion range, though those concentrations have decreased by 70% for PFOA and 84% for PFOS between 1999 and 2014, which coincides with the end of the production and phase out of PFOA and PFOS in the US. The general population has been exposed to PFOA through massive dumping of C8 waste into the ocean and near the Ohio River Valley. PFOA has been detected in industrial waste, stain-resistant carpets, carpet cleaning liquids, house dust, microwave popcorn bags, water, food and PTFE cookware.

The larvae of "O. richmondia" require relatively specialist environmental conditions for their survival and this is one reason why the species does not establish permanently in home gardens. Eggs are usually laid on the soft foliage of leaders extending into the canopy and emerge within about one week. The newly emerged larvae devour their eggshell and then require very soft foliage, as they are incapable of feeding on older, tough foliage. The larvae are extremely ravenous and require large plants; a 10-year-old vine may be needed to sustain a single larva (Sands and Scott, 1997). The fifth (final) instar larva may ringbark the stem of its host as in other "Ornithoptera", however there are no records in literature to sustain this. Pre-pupal larvae usually move away from their host plants to pupate, as larvae can be cannibalistic. The pupae are suspended in typical Papilionid fashion by crotchets at the end of their abdomen and a girdle extending around the thorax and require a protected site to survive winter. "Ornithoptera richmondia" is also the only birdwing known to enter a true diapause; artificial introduction of other "Ornithoptera" species to within the range of "O. richmondia" could interfere with this mechanism.

The bond valence model is an extension of the electron counting rules and its strength lies in its simplicity and robustness. Unlike most models of chemical bonding, it does not require a prior knowledge of the atomic positions and so can be used to construct chemically plausible structures given only the composition. The empirical parameters of the model are tabulated and are readily transferable between bonds of the same type. The concepts used are familiar to chemists and provide ready insight into the chemical restraints acting on the structure. The bond valence model uses mostly classical physics, and with little more than a pocket calculator, it gives quantitative predictions of bond lengths and places limits on what structures can be formed.

In February 1912, Baden-Powell returned to the United States and West accompanied him on tour. Baden-Powell remarked that the BSA needed better communications. After discussions with the Executive Board, Boyce offered to fund a magazine if it were published by his company in Chicago. Livingstone declined the offer, noting that the board wanted the magazine to be published from the New York office. Boyce withdrew from all administrative duties and returned to newspaper management. West learned of a Scouting magazine called "Boys' Life" and recommended it for purchase. The first cover by Norman Rockwell, "Scout at Ship's Wheel", appeared on the September 1913 issue. In 1912, Sea Scouting became an official program, based on the British Sea Scout program. Arthur Rose Eldred became the first Eagle Scout in 1912.

One non-species C oncolytic adenovirus currently in development is ColoAd1. It was created using a process of “directed evolution”. This involves the creation of new viral variants or serotypes specifically directed against tumour cells via rounds of directed selection using large populations of randomly generated recombinant precursor viruses. The increased biodiversity produced by the initial homologous recombination step provides a large random pool of viral candidates which can then be passed through a series of selection steps designed to lead towards a pre-specified outcome (e.g. higher tumor specific activity) without requiring any previous knowledge of the resultant viral mechanisms that are responsible for that outcome.

Hirano et al. previously found that the newborns did not have a true lamina propria, but instead had cellular regions called maculae flavae, located at the anterior and posterior ends of the loose vocal fold tissue. Boseley and Hartnick examined at the development and maturation of pediatric human vocal fold lamina propria. Hartnick was the first one to define each layer by a change in their cellular concentration. He also found that the lamina propria monolayer at birth and shortly thereafter was hypercellular, thus confirming Hirano's observations. By 2 months of age, the vocal fold started differentiating into a bilaminar structure of distinct cellular concentration, with the superficial layer being less densely populated than the deeper layer. By 11 months, a three-layered structure starts to be noted in some specimens, again with different cellular population densities. The superficial layer is still hypocellular, followed by an intermediate more hypercellular layer, and a deeper hypercellular layer, just above the vocalis muscle. Even though the vocal cords seem to start organizing, this is not representative of the trilaminar structure seen in adult tissues, where the layer are defined by their differential elastin and collagen fiber compositions. By 7 years of age, all specimens show a three-layered vocal fold structure, based on cellular population densities. At this point, the superficial layer was still hypocellular, the middle layer was the hypercellular one, with also a greater content of elastin and collagen fibers, and the deeper layer was less cellularly populated. Again, the distinction seen between the layers at this stage is not comparable to that seen in the adult tissue. The maturation of the vocal cords did not appear before 13 years of age, where the layers could be defined by their differential fiber composition rather than by their differential cellular population. The pattern now show a hypocellular superficial layer, followed by a middle layer composed predominantly of elastin fiber, and a deeper layer composed predominantly of collagen fibers. This pattern can be seen in older specimens up to 17 years of age, and above. While this study offers a nice way to see the evolution from immature to mature vocal cords, it still does not explain what is the mechanism behind it.

The extracellular pigment produced by "C. cupreum" is influenced by environmental factors such as pH in which low pH causes the pigments to turn yellow and high pH restores the characteristic red colour. In a photoresponse study researchers investigated the effect of variable wavelengths of visible light on the production of pigments. "C. cupreum" biomass and pigment production were variable depending on the wavelength of light used during the 7 day incubation period. The white colonies produced ascospores and a deep red, water-soluble reverse pigment. Incubation in white light lead to the largest colony diameter while green light lead to the greatest pigment production. The varying concentrations suggests pigment loss, possibly explained by nutrient depletion induced enzymatic breakdown of pigments - a common phenomena where secondary metabolites are degraded by enzymes. Further research is required to gain a comprehensive understanding of the regulation of pigment biosynthesis induced by light. "C. cupreum" has the potential to have significant commercial application for the production of natural dyes.

More generally, game semantics may be applied to predicate logic; the new rules allow a dominant quantifier to be removed by its "owner" (the Verifier for existential quantifiers and the Falsifier for universal quantifiers) and its bound variable replaced at all occurrences by an object of the owner's choosing, drawn from the domain of quantification. Note that a single counterexample falsifies a universally quantified statement, and a single example suffices to verify an existentially quantified one. Assuming the axiom of choice, the game-theoretical semantics for classical first-order logic agree with the usual model-based (Tarskian) semantics. For classical first-order logic the winning strategy for the Verifier essentially consists of finding adequate Skolem functions and witnesses. For example, if "S" denotes formula_1 then an equisatisfiable statement for "S" is formula_2. The Skolem function "f" (if it exists) actually codifies a winning strategy for the Verifier of "S" by returning a witness for the existential sub-formula for every choice of "x" the Falsifier might make.

In April 2013, Rogoff was at the center of worldwide attention with Carmen Reinhart (coauthor of the book "This Time is Different") when their widely cited study "Growth in a Time of Debt" was shown to contain computation errors which critics claim undermine its central thesis that too much debt causes recession. An analysis by Thomas Herndon, Michael Ash and Robert Pollin argued that "coding errors, selective exclusion of available data, and unconventional weighting of summary statistics led to serious errors that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies in the post-war period." Their calculations demonstrated that some high debt countries grew at 2.2 percent, rather than the percent figure initially cited by Reinhart and Rogoff. Rogoff and Reinhart claimed that their fundamental conclusions were accurate after correcting the coding errors detected by their critics. They disavowed their claim that a 90% government debt-to-GDP ratio is a specific tipping point for growth outcomes. The subject remains controversial, because of the political ramifications of the research, though in Rogoff and Reinhart's words "[t]he politically charged discussion ... has falsely equated our finding of a negative association between debt and growth with an unambiguous call for austerity."

During expansion of the Republic of Singapore Navy's capabilities in the late 1970s, the need for a dedicated coastal patrol platform was identified in order to perform the coastal surveillance and patrol mission. This need was especially apparent in 1975 during Operation Thunderstorm, where RSN resorted to using the Sea Wolf-class missile gun boats to intercept Vietnamese boat people attempting to land in Singapore. This was deemed to be operationally inefficient as it deprived RSN of a critical surface strike asset. As a result, a contract was signed with the SBEC for 12 Coastal Patrol Craft (CPC). The first vessel, RSS Swift Warrior was launched on 8 June 1980 and all 12 vessels were commissioned on 20 October 1981 by then Defence Minister, Mr Howe Yong Chong.

LightSail was working on energy storage products based on compressed-air energy storage infused with water vapour in order to retain calorimetric energy and increase energy efficiency up to marketable levels. Classic compression process creates heat, and doing so lose energy. LightSail used water vapor to recapture this heat energy, and convert it back into electricity, therefore increasing the energy efficiency of the storage device. Its first aim was to power an urban scooter, but the company goal soon shifted towards a compressed-air storage/powered generator fitting inside a standard shipping container. In December 2015, Fong announced that pilot tests for the system were scheduled to begin in 2016. By that time LightSail had started working on developing pressurized gas storage tanks for the natural gas industry. Research and development were discontinued due to emergence of financially cheaper alternatives.

Hebb's parents were both medical doctors. Donald's mother was heavily influenced by the ideas of Maria Montessori, and she home-schooled him until the age of 8. He performed so well in elementary school that he was promoted to the 7th grade at 10 years of age but, as a result of failing and then repeating the 11th grade in Chester, he graduated from the 12th grade at 16 years of age from Halifax County Academy. (Many or most of the single class of grade 9, 10 and 11 students at the Chester school failed the provincial examinations. Those in 9th and 10th grades were permitted to advance despite their failure but there was no 12th grade in Chester.) He entered Dalhousie University aiming to become a novelist. He graduated with a Bachelor of Arts degree in 1925. Afterward, he became a teacher, teaching at his old school in Chester. Later, he worked on a farm in Alberta and then traveled around, working as a laborer in Quebec.

As a result, metal-halide lamps have high luminous efficacy of around 75–100 lumens per watt, which is about twice that of mercury vapor lights and 3 to 5 times that of incandescent lights and produce an intense white light. Lamp life is 6,000 to 15,000 hours. As one of the most efficient sources of high CRI white light, metal halides were the fastest growing segment of the lighting industry. They are used for wide area overhead lighting of commercial, industrial, and public places, such as parking lots, sports arenas, factories, and retail stores, as well as residential security lighting, automotive headlamps (Often generically known as "xenon headlights") and indoor cannabis grow operations.

The NRO's first photo reconnaissance satellite program was the Corona program, the existence of which was declassified February 24, 1995, and which existed from August 1960 to May 1972 (although the first test flight occurred on February 28, 1959). The Corona system used (sometimes multiple) film capsules dropped by satellites, which were recovered mid-air by military craft. The first successful recovery from space (Discoverer XIII) occurred on August 12, 1960, and the first image from space was seen six days later. The first imaging resolution was 8 meters, which was improved to 2 meters. Individual images covered, on average, an area of about . The last Corona mission (the 145th), was launched May 25, 1972, and this mission's last images were taken May 31, 1972. From May 1962 to August 1964, the NRO conducted 12 mapping missions as part of the "Argon" system. Only seven were successful.

The integration of the transform and lighting hardware into the GPU itself set the GeForce 256 apart from older 3D accelerators that relied on the CPU to perform these calculations (also known as software transform and lighting). This reduction of 3D graphics solution complexity brought the cost of such hardware to a new low and made it accessible to cheap consumer graphics cards instead of being limited to the previous expensive professionally oriented niche designed for computer-aided design (CAD). NV10's T&L engine also allowed Nvidia to enter the CAD market with dedicated cards for the first time, with a product called Quadro. The Quadro line uses the same silicon chips as the GeForce cards, but has different driver support and certifications tailored to the unique requirements of CAD applications.

As early as 1982 there were discussions from multiple points of view about the possibility of helium shortage. One such point of discussion was to examine the usefulness of helium storage in the United States from an economic perspective. The maximisation of welfare resulting from this finite natural resource was the focal point of people of this school of thought. This economic approach is represented by the present value criterion. According to this criterion, a resource is ideally sold at the moment that the profit plus compounded interest is expected to be higher than it will be at any point in the foreseeable future, thus ensuring maximal economic value. On the other hand, there were people who advocated a more conservationist approach in the belief that the present value criterion resulted in too rapid use of the resource and too little consideration of the needs of future generations. Some scientists suggested that helium ought to be separated from as many sources as would be energetically ideal.

To speed up segmentation of large images, the work could be divided among several CPUs. One means of accomplishing this involves splitting images into tiles that are processed independently. However, regions that straddle a tile border might be split up or lost if the fragments do not meet the segmentation algorithm's minimum size requirements. A trivial workaround involves overlapping tiles, i.e. allowing each processor to consider additional pixels around its tile's border. Unfortunately this increases the computational load, since the processors on both sides of a tile boundary are performing redundant work. Also, only objects smaller than the tile overlap are guaranteed to be preserved, which means that long objects such as rivers in aerial imagery are still likely to be split. In some cases, the independent tiles' results can be fused to approximate the true results.

It's been found that people will visit their dentist more regularly than their primary physician for checkups, so the dentist's office becomes a very useful place for potentially checking for diabetes. For people who are unaware of their diabetes risk and fall into the non-White, obese, or ≥45 y old category, screening at the dentist's would have the highest odds of getting identified as someone at risk. Studies have been done to evaluate the overall effectiveness and value of prediabetes testing in the dental setting, usually at dental schools. One study has looked at screening through dental visits followed up by intervention programs such as the commercial Weight Watchers and found it a cost-effective means to identify and treat affected people in the long term. Cost is a factor people at risk might need to consider, since, on average, people diagnosed with diabetes have approximately 2.3 times higher medical expenditure that what expenditures would be in its absence.

Several explanations have historically been proposed for the variation seen in the skulls of "Stegoceras" and other pachycephalosaurs. Brown and Schlaikjer suggested that there was sexual dimorphism in the degree of doming, and hypothesized that flat-headed specimens such as AMNH 5450 ("Ornatotholus") represented the female morph of "Stegoceras". This idea was supported by a 1981 morphometric study by Champan and colleagues, which found that males had larger and thicker domes. After other flat-headed pachycephalosaurs were discovered, the degree of doming was proposed to be a feature with taxonomic importance, and AMNH 5450 was therefore considered a distinct taxon from 1979 onwards. In 1998, Goodwin and colleagues instead proposed that the inflation of the dome was an ontogenetic feature that changed with age, based on a histological study of an "S. validum" skull that showed the dome consisted of vascular, fast-growing bone, consistent with an increase in doming through age. These authors found that the supposedly distinct features of "Ornatotholus" could easily be the results of ontogeny.

The formation of an ice sheet or ice cap requires both prolonged cold and precipitation (snow). Hence, despite having temperatures similar to those of glaciated areas in North America and Europe, East Asia remained unglaciated except at higher elevations. This difference was because the ice sheets in Europe produced extensive anticyclones above them. These anticyclones generated air masses that were so dry on reaching Siberia and Manchuria that precipitation sufficient for the formation of glaciers could never occur (except in Kamchatka where these westerly winds lifted moisture from the Sea of Japan). The relative warmth of the Pacific Ocean due to the shutting down of the Oyashio Current and the presence of large east-west mountain ranges were secondary factors preventing continental glaciation in Asia.

Youngs attended UCLA, where as a freshman she started on a team that went undefeated through the regular season. They reached the semi-finals of the NCAA tournament, where they lost to Texas. The following year the Bruins reached the semi finals again, where they lost to a powerful squad from Nebraska. A knee injury caused her to miss the 1990 season. She was red-shirted, returning for the 1991 season to help the team to win the national title. The team reached the championship match again in 1992, losing to Stanford. Youngs led the Bruins to the Final Four in each of the four seasons that she played. She also earned All-American honors in each of those four years. Youngs also spent two seasons playing on the Bruins basketball team, averaging 5.7 points per game. She graduated in 1993 with a degree in history.

Public-key algorithms are most often based on the computational complexity of "hard" problems, often from number theory. For example, the hardness of RSA is related to the integer factorization problem, while Diffie–Hellman and DSA are related to the discrete logarithm problem. The security of elliptic curve cryptography is based on number theoretic problems involving elliptic curves. Because of the difficulty of the underlying problems, most public-key algorithms involve operations such as modular multiplication and exponentiation, which are much more computationally expensive than the techniques used in most block ciphers, especially with typical key sizes. As a result, public-key cryptosystems are commonly hybrid cryptosystems, in which a fast high-quality symmetric-key encryption algorithm is used for the message itself, while the relevant symmetric key is sent with the message, but encrypted using a public-key algorithm. Similarly, hybrid signature schemes are often used, in which a cryptographic hash function is computed, and only the resulting hash is digitally signed.

Soft starters can be set up to the requirements of the individual application. Compared to variable-frequency drives, soft starters require very few user adjustments. Some soft starters also include a "learning" process to automatically adapt the drive settings to the characteristics of a motor load, to reduce the power inrush requirement at the start. In pump applications, a soft starter can avoid pressure surges that could lead to "water hammer". Conveyor belt systems can be smoothly started, avoiding jerk and stress on drive components. Fans or other systems with belt drives can be started slowly to avoid belt slipping as well as air pressure surges. Soft starters are seen in electrical R/C helicopters, and allow the rotor blades to spool-up in a smooth, controlled manner rather than a sudden surge. In all systems, a soft start limits the inrush current and so improves stability of the power supply and reduces transient voltage drops that may affect other loads.

Canonical Wnt pathway activity is involved in the development of benign and malignant breast tumors. The role of Wnt pathway in tumor chemoresistance has been also well documented, as well as its role in the maintenance of a distinct subpopulation of cancer-initiating cells. Its presence is revealed by elevated levels of β-catenin in the nucleus and/or cytoplasm, which can be detected with immunohistochemical staining and Western blotting. Increased β-catenin expression is correlated with poor prognosis in breast cancer patients. This accumulation may be due to factors such as mutations in β-catenin, deficiencies in the β-catenin destruction complex, most frequently by mutations in structurally disordered regions of APC, overexpression of Wnt ligands, loss of inhibitors and/or decreased activity of regulatory pathways (such as the Wnt/calcium pathway). Breast tumors can metastasize due to Wnt involvement in EMT. Research looking at metastasis of basal-like breast cancer to the lungs showed that repression of Wnt/β-catenin signaling can prevent EMT, which can inhibit metastasis.

Proper value analysis finds its roots in the need for industrial engineers and managers to not only simplify and improve processes and systems, but also the logical simplification of the designs of those products and systems. Though not directly related to engineering economy, value analysis is nonetheless important, and allows engineers to properly manage new and existing systems/processes to make them more simple and save money and time. Further, value analysis helps combat common "roadblock excuses" that may trip up managers or engineers. Sayings such as "The customer wants it this way" are retorted by questions such as; has the customer been told of cheaper alternatives or methods? "If the product is changed, machines will be idle for lack of work" can be combated by; can management not find new and profitable uses for these machines? Questions like these are part of engineering economy, as they preface any real studies or analyses.

A number of emotional factors have been implicated in schizophrenia, with some models putting them at the core of the disorder. It was thought that the appearance of blunted affect meant that they did not experience strong emotions, however, other studies have indicated that there is often a normal or even heightened level of emotionality, particularly in response to negative events or stressful social situations. Some theories suggest positive symptoms of schizophrenia can result from or be worsened by negative emotions, including depressed feelings, low self-esteem and feelings of vulnerability, inferiority or loneliness. Chronic negative feelings and maladaptive coping skills may explain some of the association between psychosocial stressors and symptomatology. Critical and controlling behaviour by significant others (high expressed emotion) causes increased emotional arousal and lowered self-esteem and a subsequent increase in positive symptoms such as unusual thoughts. Countries or cultures where schizotypal personalities or schizophrenia symptoms are more accepted or valued appear to be associated with reduced onset of, or increased recovery from, schizophrenia.

This equation relates the judgment of a stimulus to the context in which that judgment is made. Because a judgment is assumed to be a subjective experience that is available to the subject's introspection but not to the public, the range and frequency trade-off suggests that this internal judgment by the subject can be transformed linearly for an explicit public expression expressed as a category rating. Happiness is conceived as a psychological state, according to Parducci, that is a "theoretical summation or average across many momentary psychological states, each with a certain degree of pleasure or pain". An implication from the contextual theory of happiness is that because certain premises provide us with immediate pleasure, we often infer that they heighten our long-term happiness incorrectly. Addictive drugs might produce temporary, pleasant highs, but their long-term effects are much less pleasant. It is not how much money one accrues, but rather how our earnings reflect against our prior earnings and how the earnings of our peers compare to ours. Pleasure will be greater than pain in the earnings domain in as much as our monetary gains are high relative to our comparison domains.

The group developed a standard for the steel used to fabricate rails. Originally called the "American Society for Testing Materials" in 1902, it became the "American Society for Testing And Materials" in 1961. In 2001, ASTM officially changed its name to “ASTM International" and added the tagline "Standards Worldwide". In 2014, it changed the tagline to "Helping our World Work better". Now, ASTM International has offices in Belgium, Canada, China, Peru, Washington, D.C., and West Conshohocken, PA.

From its beginning in 1942, this was a cooperative undertaking by federal, state and local health agencies. The CDC's first director, Justin M. Andrews, was also Georgia's chief malariologist. Its headquarters were in Atlanta, in part because malaria was locally endemic. Offices were located on the sixth floor of the Volunteer Building on Peachtree Street. With an annual budget of about $1 million, some 59% of its personnel were engaged in mosquito abatement and habitat control. Among its 369 employees, the main jobs at CDC at this time were entomology and engineering. In 1946, there were only seven medical officers on duty and an early organization chart was drawn, somewhat fancifully, in the shape of a mosquito.

Further testing revealed significant problems, however. To reach break-even, the system would have to meet several goals at the same time, a combination of temperature, density and the length of time the fuel is confined. In April 1986, TFTR experiments demonstrated the last two of these requirements when it produced a fusion triple product of 1.5 x Kelvin seconds per cubic centimeter, which is close to the goal for a practical reactor and five to seven times what is needed for breakeven. However, this occurred at a temperature that was far below what would be required. In July 1986, TFTR achieved a plasma temperature of 200 million kelvin (200 MK), at that time the highest ever reached in a laboratory. The temperature is 10 times greater than the center of the sun, and more than enough for breakeven. Unfortunately, to reach these temperatures the triple product had been greatly reduced to , two or three times too small for break-even.

Hydrogeophysics is a cross-disciplinary area of research that uses geophysics to determine parameters (characteristics; measurements of limitations or boundaries) and monitor processes for hydrological studies of matters such as water resources, contamination, and ecological studies. The field uses knowledge and researchers from geology, hydrology, physics, geophysics, engineering, statistics, and rock physics. It uses geophysics to provide quantitative information about hydrogeological parameters, using minimally invasive methods. Hydrogeophysics differs from geophysics in its specific uses and methods. Although geophysical knowledge and methods have existed and grown over the last half century for applications in mining and petroleum industries, hydrogeological study sites have different subsurface conditions than those industries. Thus, the geophysical methods for mapping subsurface properties combine with hydrogeology to use proper, accurate methods to map shallow hydrological study sites.

Detecting phosphorus deficiency can take multiple forms. A preliminary detection method is a visual inspection of plants. Darker green leaves and purplish or red pigment can indicate a deficiency in phosphorus. This method however can be an unclear diagnosis because other plant environment factors can result in similar discoloration symptoms. In commercial or well monitored settings for plants, phosphorus deficiency is diagnosed by scientific testing. Additionally, discoloration in plant leaves only occurs under fairly severe phosphorus deficiency so it is beneficial to planters and farmers to scientifically check phosphorus levels before discoloration occurs. The most prominent method of checking phosphorus levels is by soil testing. The major soil testing methods are Bray 1-P, Mehlich 3, and Olsen methods. Each of these methods are viable but each method has tendencies to be more accurate in known geographical areas. These tests use chemical solutions to extract phosphorus from the soil. The extract must then be analyzed to determine the concentration of the phosphorus. Colorimetry is used to determine this concentration. With the addition of the phosphorus extract into a colorimeter, there is visual color change of the solution and the degree to this color change is an indicator of phosphorus concentration. To apply this testing method on phosphorus deficiency, the measured phosphorus concentration must be compared to known values. Most plants have established and thoroughly tested optimal soil conditions. If the concentration of phosphorus measured from the colorimeter test is significantly lower than the plant's optimal soil levels, then it is likely the plant is phosphorus deficient. The soil testing with colorimetric analysis, while widely used, can be subject to diagnostic problems as a result of interference from other present compounds and elements. Additional phosphorus detection methods such as spectral radiance and inductively coupled plasma spectrometry (ICP) are also implemented with the goal of improving reading accuracy. According to the World Congress of Soil Scientists, the advantages of these light-based measurement methods are their quickness of evaluation, simultaneous measurements of plant nutrients, and their non-destructive testing nature. Although these methods have experimental based evidence, unanimous approval of the methods has not yet been achieved.

The Magnesian Limestone forms a broken west-facing scarp running from the western edge of Sunderland southwards through Houghton-le-Spring and Hetton-le-Hole to Coxhoe where its outcrop is offset to the west by the Butterknowle Fault. English Nature has defined this part of the county east of the scarp where the sequence is exposed at or near the surface, as the 'Durham Magnesian Limestone Plateau' in its assessment of 'character areas'. The occurrence of gypsum and anhydrite reflects the extreme nature of the evaporation of the shallow Zechstein Sea on occasion though such evaporites are economically valuable. They also present constraints on development as ongoing subterranean solution of these deposits causes occasional catastrophic ground collapse. Similar solution in Palaeogene times has created 'collapse breccias' of overlying strata.

Droplet precautions are intended to prevent transmission of certain pathogens spread through close respiratory or mucous membrane contact with respiratory secretions, namely respiratory droplets. Because certain pathogens do not remain infectious over long distances in a healthcare facility, special air handling and ventilation are not required to prevent droplet transmission. Infectious agents for which mere droplet precautions are indicated include "B. pertussis", influenza virus, adenovirus, rhinovirus, "N. meningitidis", and group A streptococcus (for the first 24 hours of antimicrobial therapy). A single patient room is preferred for patients who require droplet precautions. When a single-patient room is not available, consultation with infection control personnel is recommended to assess the various risks associated with other patient placement options (e.g., cohorting, keeping the patient with an existing roommate). Spatial separation of > 3 feet and drawing the curtain between patient beds is especially important for patients in multi-bed rooms with infections transmitted by the droplet route. Healthcare personnel wear a simple mask (a respirator is not necessary) for close contact with an infectious patient, which is generally donned upon room entry. Patients on droplet precautions who must be transported outside of the room should wear a mask if tolerated and follow Respiratory Hygiene/Cough Etiquette.

Chemical analysis of CBD products found that many did not contain the levels of CBD claimed in advertising. In 2022, the FDA stated that "scientific studies show possible harm to the male reproductive system, including testicular atrophy, harm to the liver, and interactions with certain medications. The FDA has not found adequate information showing how much CBD can be consumed, and for how long, before causing harm. This is particularly true for vulnerable populations like children and those who are pregnant."

The cluster is sufficiently close to the Sun that its distance can be directly measured by observing the amount of parallax shift of the member stars as the Earth orbits the Sun. This measurement has been performed with great accuracy using the Hipparcos satellite and the "Hubble Space Telescope". An alternative method of computing the distance is to fit the cluster members to a standardized infrared color–magnitude diagram for stars of their type, and use the resulting data to infer their intrinsic brightness. Comparing this data to the brightness of the stars as seen from Earth allows their distances to be estimated. Both methods have yielded a distance estimate of to the cluster center. The fact that these independent measurements agree makes the Hyades an important rung on the cosmic distance ladder method for estimating the distances of extragalactic objects.

Historians have divided the history of Cubism into phases. In one scheme, the first phase of Cubism, known as "Analytic Cubism", a phrase coined by Juan Gris a posteriori, was both radical and influential as a short but highly significant art movement between 1910 and 1912 in France. A second phase, "Synthetic Cubism", remained vital until around 1919, when the Surrealist movement gained popularity. English art historian Douglas Cooper proposed another scheme, describing three phases of Cubism in his book, "The Cubist Epoch". According to Cooper there was "Early Cubism", (from 1906 to 1908) when the movement was initially developed in the studios of Picasso and Braque; the second phase being called "High Cubism", (from 1909 to 1914) during which time Juan Gris emerged as an important exponent (after 1911); and finally Cooper referred to "Late Cubism" (from 1914 to 1921) as the last phase of Cubism as a radical avant-garde movement. Douglas Cooper's restrictive use of these terms to distinguish the work of Braque, Picasso, Gris (from 1911) and Léger (to a lesser extent) implied an intentional value judgement.

Such supplies include resistors and capacitors for RC circuit frequency equalization, if necessary; step-up transformers; perforated metal sheets or grids and insulating plastics for the stators; polymer film and conductive paint (e.g. a liquid graphite suspension) for the membrane; simple tensioning equipment for proper membrane tuning; and a frame, usually of wood, to hold everything together. A widely read resource by ESL enthusiasts is "The Electrostatic Loudspeaker Design Cookbook" () by notable ESL specialist Roger Sanders.

Aggressive space activities without adequate safeguards could significantly shorten the time between collisions and produce an intolerable hazard to future spacecraft. Some of the most environmentally dangerous activities in space include large constellations such as those initially proposed by the Strategic Defense Initiative in the mid-1980s, large structures such as those considered in the late-1970s for building solar power stations in Earth orbit, and anti-satellite warfare using systems tested by the USSR, the US, and China over the past 30 years. Such aggressive activities could set up a situation where a single satellite failure could lead to cascading failures of many satellites in a period much shorter than years.

Oscillations can often be described and analyzed using mathematics. Mathematicians have identified several dynamical mechanisms that generate rhythmicity. Among the most important are harmonic (linear) oscillators, limit cycle oscillators, and delayed-feedback oscillators. Harmonic oscillations appear very frequently in nature—examples are sound waves, the motion of a pendulum, and vibrations of every sort. They generally arise when a physical system is perturbed by a small degree from a minimum-energy state, and are well understood mathematically. Noise-driven harmonic oscillators realistically simulate alpha rhythm in the waking EEG as well as slow waves and spindles in the sleep EEG. Successful EEG analysis algorithms were based on such models. Several other EEG components are better described by limit-cycle or delayed-feedback oscillations. Limit-cycle oscillations arise from physical systems that show large deviations from equilibrium, whereas delayed-feedback oscillations arise when components of a system affect each other after significant time delays. Limit-cycle oscillations can be complex but there are powerful mathematical tools for analyzing them; the mathematics of delayed-feedback oscillations is primitive in comparison. Linear oscillators and limit-cycle oscillators qualitatively differ in terms of how they respond to fluctuations in input. In a linear oscillator, the frequency is more or less constant but the amplitude can vary greatly. In a limit-cycle oscillator, the amplitude tends to be more or less constant but the frequency can vary greatly. A heartbeat is an example of a limit-cycle oscillation in that the frequency of beats varies widely, while each individual beat continues to pump about the same amount of blood.

These cables use two parallel bus wires which carry electricity but do not create significant heat. They are encased in a semi-conductive polymer. This polymer is loaded with carbon; as the polymer element heats, it allows less current to flow so the cable is inherently power saving and only delivering heat and power where and when required by the system. The cables are manufactured and then irradiated and by varying both the carbon content and the dosage then different tape with different output characteristics can be produced. The benefits of this cable are the ability to cut to length in the field. It is more rugged, and much more reliable than a constant wattage cable; it cannot over-heat itself so it can be crossed over, but it is bad practice to install tape in this way. Self-regulating and constant wattage heating cables have specific maximum exposure temperature, which means that if they are subject to high temperatures then the tape can be damaged beyond repair.

Five infantry divisions of the AIF saw action in France and Belgium, leaving Egypt in March 1916. I Anzac Corps subsequently took up positions in a quiet sector south of Armentières on 7 April 1916 and for the next two and a half years the AIF participated in most of the major battles on the Western Front, earning a formidable reputation. Although spared from the disastrous first day of the Battle of the Somme, within weeks four Australian divisions had been committed. The 5th Division, positioned on the left flank, was the first in action during the Battle of Fromelles on 19 July 1916, suffering 5,533 casualties in a single day. The 1st Division entered the line on 23 July, assaulting Pozieres, and by the time that they were relieved by the 2nd Division on 27 July, they had suffered 5,286 casualties. Mouquet Farm was attacked in August, with casualties totalling 6,300 men. By the time the AIF was withdrawn from the Somme to re-organise, they had suffered 23,000 casualties in just 45 days.

Algorand uses VRFs to perform cryptographic sortition. In this platform, every block produces a new random selection seed, and a user secretly checks whether they were selected to participate in the consensus protocol by evaluating a VRF with their secret participation key and the selection seed. (This also produces a proof, which the user can send to anyone to show that they have been selected to participate.) Thusly, accounts are selected to propose blocks for a given round. In this manner, VRFs prevent users from gaining staking advantages by registering multiple accounts. The particular VRF that Algorand uses is based on elliptic-curve cryptography, specifically Curve25519; proposed by Sharon Goldberg, Moni Naor, Dimitris Papadopoulos, Leonid Reyzin, and Jan Včelák, the function is currently undergoing standardization as an IETF Internet Draft. Algorand's own implementation of this function has been open-source since October 2018.

In a semi-solid flow cell, the positive and negative electrodes are composed of particles suspended in a carrier liquid. The positive and negative suspensions are stored in separate tanks and pumped through separate pipes into a stack of adjacent reaction chambers, where they are separated by a barrier such as a thin, porous membrane. The approach combines the basic structure of aqueous-flow batteries, which use electrode material suspended in a liquid electrolyte, with the chemistry of lithium-ion batteries in both carbon-free suspensions and slurries with conductive carbon network. The carbon free semi-solid redox flow battery is also sometimes referred to as Solid Dispersion Redox Flow Battery. Dissolving a material changes its chemical behavior significantly. However, suspending bits of solid material preserves the solid's characteristics. The result is a viscous suspension that flows like molasses.

As time went on, competing for axial turbines became dramatically more efficient and powerful, and the second stage of reduction gears was introduced in most cutting-edge U.S. naval ships of the 1930s. The improvement in steam technology gave the U.S. Navy aircraft carriers a clear advantage in speed over both Allied and enemy aircraft carriers, and so the proven axial steam turbines became the preferred form of propulsion until the 1973 oil crisis took place. It drove the majority of new civilian vessels to turn to diesel engines. Axial steam turbines still had not exceeded 50% efficiency by that time, and so civilian ships chose to use diesel engines due to their superior efficiency. By this time, the comparably efficient Tesla turbine was over 60 years old.

Advances in genomics have enabled a variety of new methods and gene targets to be identified for possible applications. DNA microarrays used in a variety of next-gen sequencing can identify thousands of genes simultaneously, with analytical software looking at gene expression patterns, and orthologous genes in model species to identify function. This has allowed a variety of possible vectors to be identified for use in gene therapy. As a method for creating a new class of vaccine, gene delivery has been utilized to generate a hybrid biosynthetic vector to deliver a possible vaccine. This vector overcomes traditional barriers to gene delivery by combining "E. coli" with a synthetic polymer to create a vector that maintains plasmid DNA while having an increased ability to avoid degradation by target cell lysosomes.

Through the efforts of both staff and volunteers, the Experimental Aircraft Association in Oshkosh, Wisconsin produced two reproductions of the "Spirit of St. Louis", powered by Continental R-670-4 radial engines, the first in 1977 (of which was to be based on a conversion from a B-1 Brougham; the aircraft proved to be too badly deteriorated to be used in that manner), flown by EAA founder Paul Poberezny to commemorate the 50th anniversary of Lindbergh's flight across the Atlantic Ocean and subsequent tour of the United States. This example is now on display in the main museum gallery. A second reproduction, started from scratch in 1977 and first flown in November 1990, continues to fly at air shows and commemorative events. Both of the EAA reproductions were registered under the original's N-X-211.

The first attempt as a marine weather program within the United States was initiated in New Orleans, Louisiana, by the United States Army Signal Corps. A January 23, 1873, memo directed the New Orleans Signal Observer to transcribe meteorological data from the ship logs of those arriving in port. Marine forecasting responsibility transferred from the United States Navy to the Weather Bureau in 1904, which enabled the receipt of timely observations from ships at sea. The basis for OPC's mission can be traced back to the sinking of the "Titanic" in April 1912. In response to that tragedy, an international commission was formed to determine requirements for safer ocean voyages. In 1914, the commission's work resulted in the International Convention for the Safety of Life at Sea, of which the United States is one of the original signatories.

Laura Minelli, a professor of pre-Columbian studies at the University of Bologna, has discovered something which she believed to be a seventeenth-century Jesuit manuscript that describes literary "quipus", titled . This manuscript consists of nine folios with Spanish, Latin, and ciphered Italian texts. Owned by the family of Neapolitan historian Clara Miccinelli, the manuscript also includes a wool "quipu" fragment. Miccinelli believes that the text was written by two Italian Jesuit missionaries, Joan Antonio Cumis and Giovanni Anello Oliva, around 1610–1638, and Blas Valera, a mestizo Jesuit sometime before 1618. Along with the details of reading literary "quipus", the documents also discuss the events and people of the Spanish conquest of Peru. According to Cumis, since so many "quipus" were burned by the Spanish, very few remained for him to analyze. As related in the manuscript, the word Pacha Kamaq, the Inca deity of earth and time, was used many times in these "quipus", where the syllables were represented by symbols formed in the knots. Following the analysis of the use of "Pacha Kamaq", the manuscript offers a list of many words present in "quipus". However, both Bruce Mannheim, the director of the Center for Latin American Studies at the University of Michigan, and Colgate University's Gary Urton, question its origin and authenticity. These documents seem to be inspired freely by a 1751 writing of Raimondo di Sangro, Prince of Sansevero.

Thiel's Professor in Breslau recommended Thiel to the Research Institute of the German army ordnance office of under-secretary Prof. Karl Erich Schumann at the University of Berlin. Thiel's previous findings had technological applicability and therefore he was able to continue his fundamental research in a leading position. Late 1934 or early 1935 Thiel became research instructor at Reichswehrministerium. Schumann accompanied many diploma theses and dissertations, including that of Wernher von Braun, who completed his dissertation in 1934. The contacts between the testing ground in Kummersdorf and Schumann's Institute was close, the eastern part of the site in Kummersdorf served as an experimental base for Schumann's institutes, in the west a group of scientists around Major Walter Dornberger carried out their experiments. Here Thiel got to know Walter Dornberger and Wernher von Braun.

Hydroelectric power is power created from the energy of running water. This water is usually stored and controlled by dams. Its productivity changes in accordance to how much rainfall is produced annually. In 2018, California ranked second in the United States for conventional hydroelectric generation, however this is highly variable depending on droughts. For instance it obtained 21% of its electricity through hydroelectric power sources in 2017. This was higher than the previous year when only 14% of its electricity was produced through hydroelectric power. A drought in 2012 led to a reduction in the generation of hydroelectric power. Because of this, in 2014 the Energy Commission of California began to track the conditions on how the drought started. Utilities responded to the decrease in precipitation and lack of hydroelectric power by making short-term market purchases and relying on other renewable sources of electricity. Recovery from the drought started in late 2016, partly due to increased precipitation that restored hydroelectric power to normal conditions.

In 1910, the American geologist Mignon Talbot was walking with her sister Ellen to Holyoke, Massachusetts, in the eastern US, when they passed a farm and noticed a small hill nearby. It had a gravel pit at one side, and was formed by an accumulation of sand, gravel, and boulders left by a receding glacier. Talbot noticed a white streak on a sandstone boulder at the bottom of the gravel pit, and upon discovering these were bones, she told her sister she had found a "real live fossil". This was because many fossil tracks had previously been discovered in the Connecticut Valley (that she had often taken her students to see), but few actual dinosaur skeletons, and none at Mount Holyoke. She was granted permission by the land owner to collect the specimen for Mount Holyoke College (an all-women's college a few miles from there), where she was head of the geology department.

The Intelligent Platform Management Interface (IPMI) is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system's CPU, firmware (BIOS or UEFI) and operating system. IPMI defines a set of interfaces used by system administrators for out-of-band management of computer systems and monitoring of their operation. For example, IPMI provides a way to manage a computer that may be powered off or otherwise unresponsive by using a network connection to the hardware rather than to an operating system or login shell. Another use case may be installing a custom operating system remotely. Without IPMI, installing a custom operating system may require an administrator to be physically present near the computer, insert a DVD or a USB flash drive containing the OS installer and complete the installation process using a monitor and a keyboard. Using IPMI, an administrator can mount an ISO image, simulate an installer DVD, and perform the installation remotely.

Because population turnover rates of individual taxa are much less than net rates of sediment accumulation, the biological remains of successive, noncontemporaneous populations of organisms may be admixed within a single bed, known as time-averaging. Because of the slow and episodic nature of the geologic record, two apparently contemporaneous fossils may have actually lived centuries, or even millennia, apart. Moreover, the "degree" of time-averaging in an assemblage may vary. The degree varies on many factors, such as tissue type, the habitat, the frequency of burial events and exhumation events, and the depth of bioturbation within the sedimentary column relative to net sediment accumulation rates. Like biases in spatial fidelity, there is a bias towards organisms that can survive reworking events, such as shells. An example of a more ideal deposit with respect to time-averaging bias would be a volcanic ash deposit, which captures an entire biota caught in the wrong place at the wrong time (e.g. the Silurian Herefordshire lagerstätte).

By the late 1600s, Russian settlers started making the long trek to Siberia in greater numbers in order to find new opportunities and lands to claim, away from the densely populated tracts of European Russia. In fact, some peasants chose to move away from their western homes because of poor soil conditions in their native regions, hoping to settle down on some of the chernozem soil that Siberia had to offer. Families also had the chance to improve their standing in society and escape poverty by taking advantage of the more lenient taxing system the Tsar offered in Siberia; for each acre of land that a family tilled for the tsar, they were given permission to plough five acres of government land for their own benefit. In addition to this, early settlers enjoyed a 10-year tax exemption, an incentive for families to migrate eastward.

CTSS used a modified IBM 7090 mainframe computer that had two 32,768 (32K) 36-bit-word banks of core memory instead of the default configuration which provides only one. One bank was reserved for the time-sharing supervisory program, the other for user programs. CTSS had a protected-mode kernel, the supervisor's functions in the A-core (memory bank A) could be called only by software interrupts, like in the modern operating systems. Causing memory-protection interrupts were used for software interrupts. Processor allocation scheduling with a quantum time unit 200 ms, was controlled by a multilevel feedback queue. It also had some special memory-management hardware, a clock interrupt and the ability to trap certain instructions.

Prolonged lack of insulin can also result in diabetic ketoacidosis, characterized by persistent fatigue, dry or flushed skin, abdominal pain, nausea or vomiting, confusion, trouble breathing, and a fruity breath odor. Blood and urine tests reveal unusually high glucose and ketones in the blood and urine. Untreated ketoacidosis can rapidly progress to loss of consciousness, coma, and death. The percentage of children whose type 1 diabetes begins with an episode of diabetic ketoacidosis varies widely by geography, as low as 15% in parts of Europe and North America, and as high as 80% in the developing world.

Lasers have been used to indirectly generate non-coherent extreme UV (EUV) light at 13.5 nm for extreme ultraviolet lithography. The EUV light is not emitted by the laser, but rather by a tin or xenon plasma which is excited by an excimer or laser. Fabrication of feature sizes of 10 nm has been demonstrated in production environments, but not yet at rates needed for commercialization. However, this is expected by 2016. This technique does not require a synchrotron, and EUV sources, as noted, do not produce coherent light. However vacuum systems and a number of novel technologies (including much higher EUV energies than are now produced) are needed to work with UV at the edge of the X-ray spectrum (which begins at 10 nm). As of 2020, EUV is in mass production use by leading edge foundries such as TSMC and Samsung.

Values of "socialism" have roots in pre-capitalist institutions such as the religious communes, reciprocal obligations and communal charity of medieval Europe, the development of its economic theory primarily reflects and responds to the monumental changes brought about by the dissolution of feudalism and the emergence of specifically capitalist social relations. As such it is commonly regarded as a movement belonging to the modern era. Many socialists have considered their advocacy as the preservation and extension of the radical humanist ideas expressed in Enlightenment doctrine such as Jean-Jacques Rousseau's "Discourse on Inequality", Wilhelm von Humboldt's "Limits of State Action", or Immanuel Kant's insistent defense of the French Revolution.

Such magnetic fields may be advected inward from the interstellar medium or generated by a magnetic dynamo within the disk. Magnetic fields strengths at least of order 100 Gauss seem necessary for the magneto-centrifugal mechanism to launch powerful jets. There are problems, however, in carrying external magnetic flux inward towards the central star of the disk. High electric conductivity dictates that the magnetic field is frozen into the matter which is being accreted onto the central object with a slow velocity. However, the plasma is not a perfect electric conductor, so there is always some degree of dissipation. The magnetic field diffuses away faster than the rate at which it is being carried inward by accretion of matter. A simple solution is assuming a viscosity much larger than the magnetic diffusivity in the disk. However, numerical simulations, and theoretical models, show that the viscosity and magnetic diffusivity have almost the same order of magnitude in magneto-rotationally turbulent disks. Some other factors may possibly affect the advection/diffusion rate: reduced turbulent magnetic diffusion on the surface layers; reduction of the Shakura–Sunyaev viscosity by magnetic fields; and the generation of large scale fields by small scale MHD turbulence –a large scale dynamo. In fact, a combination of different mechanisms might be responsible for efficiently carrying the external field inwards towards the central parts of the disk where the jet is launched. Magnetic buoyancy, turbulent pumping and turbulent diamagnetism exemplify such physical phenomena invoked to explain such efficient concentration of external fields.

Oslo is sandwiched between the Oslo Fjord and wooded areas. Woods serve as an important feature to this municipality. More than two-thirds of the city is protected forests; in recent surveys over 81% of Oslo residents said they have gone to these forests at least once in the last year. These forests are protected, as Oslo adheres to ISO14001 for its forest management – the trees are controlled under “living forest” standards, which means that limited harvesting is acceptable. In addition to its extensive forest system, the city compounds its exposure to nature by bringing the natural environment into the urban setting. Being an already compact city (after all, two-thirds is forest) the city allocates around 20% of its urban land to green spaces; the local government is in the process of creating a network of paths to connect these green areas so that citizens can walk and ride their bikes undisturbed. In addition to the expanding park accessibility, the city has also restored the city's river the Akerselva, which runs through Olso's center. Because the water feature is near sets of dense housing, the city made the river more appealing and accessible to residents by adding waterfalls and nature trails; altogether the city has 365 kilometers worth of nature trails.

As a result, "a majority of the approximately 80 presidents at the meeting said that they did not intend to participate in the "U.S. News" reputational rankings in the future." However, the decision to fill out the reputational survey was left to each individual college. The statement stated that its members "have agreed to participate in the development of an alternative common format that presents information about their colleges for students and their families to use in the college search process."

There has been a growing research interest in the benefits of bilingualism against age-related cognitive decline. Klein & Viswanathan found that the normal decrease in attention control observed in older adults was reduced in bilinguals, suggesting that bilingualism may protect against age-related cognitive deficits. Elderly bilinguals show better task-switching skill, can ignore unrelated information, and can choose the best phrasing. Bilingualism may be one of the environmental factors which contributes to 'cognitive reserve'. Cognitive reserve is the idea that engaging in stimulating physical or mental activity can maintain cognitive functioning in healthy aging and delay the onset of dementia-related memory losses. Contributing factors include education, occupational status, higher socioeconomic class, and doing physical, intellectual and social activities.

Modern museum dioramas may be seen in most major natural history museums. Typically, these displays use a tilted plane to represent what would otherwise be a level surface, incorporate a painted background of distant objects, and often employ false perspective, carefully modifying the scale of objects placed on the plane to reinforce the illusion through depth perception in which objects of identical real-world size placed farther from the observer appear smaller than those closer. Often the distant painted background or sky will be painted upon a continuous curved surface so that the viewer is not distracted by corners, seams, or edges. All of these techniques are means of presenting a realistic view of a large scene in a compact space. A photograph or single-eye view of such a diorama can be especially convincing since in this case there is no distraction by the binocular perception of depth.

"Mesembryanthemum cordifolium" can be planted as a fast-growing, not hardy, groundcover in flower boxes and around traffic lights. The plant needs a sunny spot and well drained soil. This plant is also ideal for covering walls, rockeries and areas bare of grass. Due to its quick growth, it is useful to prevent the growth of weeds in the field where it is planted. It can also survive without problems in a pot, where it is grown in hanging baskets so the long trailing branches can hang down with their leaves spaced out. Over-wintering should take place in a frost-free, sunny place at approximately . No serious insect or disease problems are known. In addition to the species and the hybrid 'Red Apple', one also encounters the variety "A." x. 'Mezoo', a mutant of 'Red Apple' whose variegated leaves have creamy white edges, and rarely on a white-flowering form.

In 2018, a sheared-flow stabilized Z-pinch demonstrated neutron generation. It was built by a fusion company, Zap Energy, Inc., a spin-out from the University of Washington, and funded by strategic and financial investors and grants from the Advanced Research Projects Agency – Energy (ARPA–E). Flow stabilized plasma remained stable 5,000 times longer than a static plasma. A mix of 20% deuterium and 80% hydrogen by pressure, produced neutron emissions lasting approximately 5 μs with pinch currents of approximately 200 kA during an approximately 16 μs period of plasma quiescence. Average neutron yield was estimated to be (1.25±0.45)×10 neutrons/pulse. Plasma temperatures of 1–2 keV (12–24 million °C) and densities of approximately 10 cm with 0.3 cm pinch radii were measured.

Unlike the physical sciences where a narrower, more specified system is studied, futurology concerns a much bigger and more complex world system. The methodology and knowledge are much less proven than in natural science and social sciences like sociology and economics. There is a debate as to whether this discipline is an art or science, and it is sometimes described as pseudoscience; nevertheless, the Association of Professional Futurists was formed in 2002, developing a Foresight Competency Model in 2017, and it is now possible to academically study it, for example at the FU Berlin in their master's course. In order to encourage inclusive and cross-disciplinary discussions about the futures Studies, UNESCO declared December 2nd as World Futures Day.

The ability to grow up functional adult tissues indefinitely in culture through Directed differentiation creates new opportunities for drug research. Researchers are able to grow up differentiated cell lines and then test new drugs on each cell type to examine possible interactions "in vitro" before performing "in vivo" studies. This is critical in the development of drugs for use in veterinary research because of the possibilities of species-specific interactions. The hope is that having these cell lines available for research use will reduce the need for research animals used because effects on human tissue "in vitro" will provide insight not normally known before the animal testing phase.
