There's a built-in stop-watch in the brain, according to MIT neuroscientists.
They have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control.
Although daily life is extremely dependent on precise timing - whether it's walking, speaking or playing the piano - surprisingly little has been known about how time is represented in the activity of brain cells.
The team trained two macaque monkeys to perform a simple eye-movement task. After receiving a 'go' signal, the monkeys were free to perform the task at their own speed. The researchers found that neurons in the prefrontal cortex and the striatum that consistently fired at specific times — 100 milliseconds, 110msec, 150msec, and so on — after the 'go' signal.
Like a stopwatch, these neurons provided a fine-scale coverage over a period of several seconds. The combined activity of these neurons provided 'time stamps' that could specify any given time point with remarkable precision - less than 50 milliseconds.
More work is needed to establish how the brain produces this time code, and how it is used to control behavior and learning.
In the longer term, the ability to read the brain's natural time-code might help in the development of neural prosthetic devices for conditions such as Parkinson's disease, in which neurons in the prefrontal cortex and basal ganglia are disrupted and the ability to control the timing of movements is impaired.
The results are published in the Proceedings of the National Academy of Sciences.


At St David’s we strive to ensure all pupils are equipped with the necessary tools to be confident speakers, listeners, readers and writers. Our aim is to inspire and motivate pupils to ensure they reach their full potential, as well as equipping them with the essential skills they will take forward to secondary school.
In order to ensure pupils make good progress in each year group, a range of grammar, spelling, reading and writing activities are taught, and these are tailored to meet the needs of the individual child. As far as possible, links are made to other areas of the curriculum and encompass pupils’ interests in order to maintain high levels of engagement and foster a passion for reading and writing.
Pupils enjoy exciting and memorable trips to places such as the Globe Theatre and in-school events are organised such as ‘Roald Dahl Day’ which bring their learning to life.


Music has helped many people through tough times. During the pandemic, the music I have listened to has been comforting, calming, melancholy, and uplifting. When experiencing difficult times, sharing music and art can help us realize that we are not alone. Learning how to use art and music as forms of communication can help bring comfort to ourselves and others, help manage feelings, and as in the case of this prompt, offer opportunities for connection.

This is the famous fig tree under which the Buddha attained enlightenment, and is sacred to Hindus and Jains, as well as to Buddhists. The tree can grow very large, up to 30m tall.
The peepal tree (Ficus religiosa) has many traditional medicinal uses, from asthma to diabetes, gastric and genitourinary problems. In Ayurvedic medicine the bark is the most important part of the tree, but leaves, latex, fruits and seeds are also used. The latex in particular is valuable as a fungicide.
In the late 18th and early 19th centuries the East India Company controlled much of the Indian subcontinent. Keen to exploit and export valuable natural commodities, the Company set out to record the flora of India and commissioned Indian artists to create detailed botanical illustrations. Many of the plants were known through their use in Ayurvedic medicine. One of the world’s oldest medicinal systems, it has been practised in India for 3,000 years.
Company School style paintings became popular with wealthy Europeans. It was not uncommon for East India Company officials (who were not employed as medics or botanists) to build their own personal collections of paintings depicting Indian flora and fauna. We cannot be sure how local amateur botanist Richard Cresswell came by this collection of 86 Company School works. It is possible Henry Creighton commissioned them during his time as a judge in Calcutta and that on his death the works came back to the UK with his daughter Frances who later married Richard Cresswell.

How to Install Digital Optical cable?
The telegraph and telephone were two inventions that changed the course of human history. They allowed people to communicate over long distances, making life easier and propelling the world into a newer, more modern age. Today, people still use the same kinds of copper wires that powered the first telegraphs and telephones. This technology is old, unreliable, and as the needs of people grow, will soon be obsolete. Copper wires are making way for the next new technology, namely, fiber optics. Fiber optic cables are used in a variety of ways, from delivering television signals to homes to transferring data between computers that are thousands of miles apart. They are a better alternative to copper wires when it comes to computer networks.
This guide aims to help people who are considering wiring their networks using fiber optic cables, by first explaining how they work and why they should be used. Installing and maintaining a computer network with fiber optics is not difficult, especially if users follow the step-by-step instructions detailed in the guide. Fiber optic cables and other devices needed to connect a home network can be bought at specialty electronic stores or ordered through electronics and computer parts suppliers. However, those who prefer to shop online should consider eBay. This site provides buyers a large range of choices when it comes to computer networking supplies.
How Fiber Optic Cables Work
Fiber optic cables use glass fiber strands covered with an insulated casing to send and receive communication signals using light pulses. Each cable can have up to a thousand strands of fiber, with the ability to send terabytes of data in a second. These types of cables have very high bandwidth and can be used over long distances with very little data degradation.


La France est un des grands pays de l'Europe occidentale.
I learned this sentence from the book French for Reading Knowledge. The word "des" does not make sense for me. "un grands pays" (a great country) looks right to me. Is it an indefinite article or a partitive article? Or something else? What is the grammar here?


Chinese meridian theory
(chy-NEEZ meh-RIH-dee-un THEER-ee)
In traditional Chinese medicine, meridians are channels that form a network in the body, through which qi (vital energy) flows. Blocked qi causes pain or illness. The flow of qi is restored by using pressure, needles, suction, or heat at hundreds of specific points along the meridians.


Rayleigh-Jeans law and Wien’s formulae were failed to solve the problem of distribution of spectral radiance among various wavelengths in cavity radiations because these formulas were based upon the classical theory.
Planck’s quantum theory of radiation
In 1900, Max Planck gave a new concept about the nature of radiation, called the quantum theory of radiation in which Planck assumed the discrete nature of radiation. He assumed the atoms of the cavity emit and absorb radiation in the form of packets of energy, called quanta. The energy of each quantum is directly proportional to frequency.
E ∝ f
where h is Planck’s constant.
Max Planck made the following assumptions derive his radiation law:
- The atoms of the cavity behave like tiny harmonic oscillators.
- The oscillators radiate and absorb energy only in the form of packets or bundles of electromagnetic waves.
- An oscillator can emit or absorb any amount of energy which is the integral multiple of “hf ” which is mathematically expressed as:
Where n is an integer.

The use of a Christmas tree indoors appears to have begun in
The tradition of the Christmas tree eventually spread through out
When the German immigrants went to American they also brought along their Christmas trees. In the 1830's most Americans still considered the Christmas tree an oddity. One of the first public displays of a Christmas tree was set up by German Settlers in
Early Christmas trees were often decorated with apples, nuts, cookies, colored popcorn and candles. The invention of electricity in the early 20th century and use of electrical Christmas lights helped spread the use of the Christmas tree.
It is now common in most communities through out the
A beautifully decorated evergreen tree, with colored lights ablaze inspires in many warm memories of Christmases long past. The Christmas tree has become one of the most beloved and well know holiday symbols.
The tradition of a holiday tree has been around since ancient times and has played an important part in winter celebrations for many centuries. Many pagan festivals used trees when honoring their gods and spirits. In
There have also been many legends surrounding the lore of the Christmas tree. In one story Saint Boniface, an English monk, came upon a group of pagans who had gathered around an oak tree and were preparing to sacrifice a child. To stop the sacrifice and save the child, the Saint flattened the oak tree with one blow of his fist. A small fir sprang up in its place, which Saint Boniface told the pagans was the Tree of Life and represented the life of Christ.
Another legend tells of Martin Luther, the founder of the Protestant religion, walking through the woods late one night. As it was clear, many stars were shining through the branches of the trees giving the impression of twinkling lights. Luther was so inspired by the beauty of the sight that he cut down a small evergreen and brought it home. He recreated the stars by putting candles on the tree's branches.


On the Death of a Lady's Owl.
1 THE Owl expires! death gave the dreadful word,
2 And lovely Anna weeps her fav'rite bird.
3 Ye feather'd choir in willing throngs repair,
4 And sooth the sorrows of the melting fair;
5 In sounds of woe the dear-departed greet,
6 With cypress strew, ye doves, the green retreat;
7 The fateful raven tolls the passing bell,
8 The solemn dirge be sung by Philomel;
9 Sir Chanticlear, a chief of hardy race,
10 Shall guard from kites and daws the sacred place.
11 With your just tears a bard shall mix his own,
12 And thus, in artless verse, inscribe the stone.
13 INTERR'D within this little space
14 The bird of wisdom lies;
15 Learn hence, how vain is ev'ry grace,
16 How fruitless to be wise.
17 Can mortal stop the arm of Death
18 Who ne'er compassion knew?
* Adonis.Venus' lover robb'd of breath,
20 He, Anna's darling slew.
21 Ah happy bird, to raise those sighs
22 Which man could ne'er obtain!
23 Ah happy bird, to cloud those eyes
24 That fir'd each kneeling swain!
25 Thrice bless'd thy life, her joy, her bliss,
26 Thrice bless'd thy happy doom;
27 She gave thee many a melting kiss,
28 She wept upon thy tomb.

BOB HIRSHON (host):
How our mouths talk to our gut. I’m Bob Hirshon and this is Science Update.
When we put a bite of food into our mouths and start chewing, the whole body pays attention, according to Rutgers nutritional scientist Paul Breslin. At a recent meeting of the American Association for the Advancement of Science, he explained that an enzyme called salivary amylase breaks down starches into smaller molecules. Chemical sensors in the mouth analyze them and send the information downstream.
PAUL BRESLIN (Rutgers University):
The best way to process foods in your body is when you know they’re coming in and you can be prepared and ready for them.
In this case, the pancreas starts secreting insulin to regulate the incoming sugars. Breslin says people with low levels of amylase in their saliva may be susceptible to metabolic disorders like diabetes. He says understanding chemical sensing and communication like this could help scientists prevent and treat a host of metabolic and immune disorders. I’m Bob Hirshon, for AAAS, the science society.

How did that arrowhead end up underground in the first place?
A Native American left it on the surface hundreds of years ago.
Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old.
To determine the ages of these specimens, scientists need an isotope with a very long half-life.
The most widely known form of radiometric dating is carbon-14 dating.
This is what archaeologists use to determine the age of human-made artifacts. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old.

The Visitation of the Blessed Virgin Mary to Elizabeth is a festival of the Western Christian calendar. It is celebrated on 31 May annually.
The Visitation recalls the event recounted in Luke 1.39. Mary, the Mother of Jesus, after the Annunciation that she will conceive, sets out to visit her relative (the exact relationship is uncertain) Elizabeth, who is also pregnant. Elizabeth, carry the unborn John the Baptist, feels her child leap in the womb on the sound of Mary's greeting. Filled with the Holy Spirit, both women make prophetic pronouncements that a time of fulfilment is upon them. Mary's prophetic hymn, the Magnificat, is repeated at vespers in many church traditions. The beginning of Elizabeth's statement — "Blessed are you among women, and blessed is the fruit of your womb" — is part of the popular prayer Ave, Maria.
The first celebration of the feast of the Visitation occurred in 1263 at Franciscan Order General Chapter. The feast proved popular and spread quickly. Many Protestant churches celebrate the Visitation even though they may have rejected some of the more ancient feasts of Mary. This is mostly due to the feast's sound origin in a biblical text.


Ode-min Giizis is known as Strawberry Moon, and this term is how the month of June is referred to by Anishinaabe people in this area. Strawberries are the first fruit to grow upon Mother Earth, and through the traditional teachings and Creation story of the first strawberry, they teach us about growth, forgiveness, self-discipline and peace. We will explore and compare the varieties of strawberries we have available to us today and discuss the differences in growth rate and production methods. Students will have the opportunity to extract DNA from a strawberry, learn about the structure of DNA and how genetic information is passed through generations. We might even get a taste of this sweet traditional fruit!
Th Ode-min workshop can be done in any classroom setting, though we always appreciate the opportunity to make use of lab spaces here at the University.

Income inequality in the U.S. is contributing to the growth of financial insecurity in retirement, exacerbated by a shift from pensions to individual 401(k) savings accounts, according to a new report by the U.S. National Institute On Retirement Security.
It found in 2019, white households across three generations — baby boomers, generation X and millennials — owned 75 per cent or more of their generation’s financial assets, with ownership especially concentrated among white households in the top 25 per cent of net worth.
White baby boomers owned 91 per cent of their generation’s financial assets in 2019, compared to Black baby boomers (three per cent) and Hispanic baby boomers (two per cent), while the top five per cent of baby boomers by net worth owned a greater percentage of that generation’s financial assets in 2019 (58 per cent) than in 2004 (52 per cent).
“This stark inequality is even more problematic because the U.S. has largely shifted to a retirement system built around the individual ownership of financial assets in 401(k) or individual retirement accounts rather than pensions,” said Tyler Bond, research manager for the institute and the report’s author, in a press release. “Few financial assets during one’s working years translates into retirement insecurity later in life.”


The recycling of bioplastics is not necessarily easier than the recycling of conventional polymers. Antje Lieske is conducting research at the Fraunhofer IAP on the recycling of raw materials contained in granulate materials. The goal is to use the recycled materials to produce new products. In order to do this, the granulate materials have to be broken down into their original components—as efficiently and effectively as possible. The additives that chemically alter the properties of the plastic pose a particular difficulty.
In addition to the chemical difficulties it is also necessary to master the logistics: “Polylactic acid, for example, which is a bioplastic, is only worth separating in large quantities. This is why we recycle only six to seven percent of the utilised plastic, even though we actually collect everything in our recycling system,” said Lieske.
The foundations, however, have been created—Lieske can produce new products from residual materials. The video shows you how it works in detail.

Surabaya is Indonesia’s second largest city but is not well known to the outside world. Yet in 1900, Surabaya was a bigger city than Jakarta and one of the main commercial centers of Asia. Collapse of sugar exports during the 1930s depression, followed by the Japanese occupation, revolution, and independence, brought on a long period of stagnation and retreat from the international economy. Not until the export boom of the 1990s did Surabaya regain prominence as Southeast Asia’s leading non–capital–city industrial area.
Previous thinking on Indonesia is being reassessed in light of recent political and economic upheaval. Surabaya, City of Work offers an alternative to the Jakarta-centric focus of most writing on the country. It is a multifaceted view of a fascinating and complex city in the dimensions of time and space, economy and society, and the current transition toward decentralization makes it highly topical.
Exploration of this eventful economic history gives new insight into Indonesia’s modern economic development. Industrialization is recognized as being associated with rapid urbanization, but this is the first study of Indonesia from an explicitly urban perspective. Surabaya, City of Work takes a broad approach that links industrialization to socioeconomic trends, the increasing role of government, changing land use, and trade patterns.
This well–illustrated local history encompassing national events and trends will be a central work on Indonesia for years to come.

We’re taught to believe that the hospital is where you go when an illness or injury is more than you can treat at home. We’re told doctors, nurses and surgeons have our best interests at heart and are trained for years to know how to make life-saving decisions in emergency situations.
The reality is that hospitals aren’t nearly as safe as you think.
The infographic below gives you just a peek into some of the top reasons why the United States ranks last out of 19 developed nations in preventable deaths at hospitals.

Published December 06, 2013
DOTHAN, Ala – State officials are working to educate authorities about the dangers of Africanized honey bees.
The Dothan Eagle reports Dennis Barclift, state apiarist with the Alabama Department of Agriculture and Industries, held a workshop this week in Dothan with 911 operators and emergency personnel about the proper way to handle reports of bee swarms and stings.
The Africanized honey bee or "killer bee" has been in the U.S. since 1990 and looks just like a typical honey bee but is extremely aggressive. Experts say they're more easily provoked, quicker to swarm and attack in greater numbers.
Barclift said there are no known instances of the bees in Alabama in any significant number, but they're spreading quickly in Florida and moving north.


Citing concerns over massive decline in bee populations due to Colony Collapse Disorder, the French health and safety agency, ANSES, said it will ban the use of Syngenta’s pesticide, Cruiser OSR, used to coat rapeseed plants. The French ban on the pesticide will take effect before the start of the next rapeseed sowing campaign in late summer, reported Reuters.
Cruiser OSR contains thiamethoxam as one of the active ingredients, a compound which is part of the neonicotinoids family. Neonicotinoids are systemic pesticides used to coat seeds. For years evidence has been mounting about the detrimental impact of systemic pesticides on bees. This year alone, four new studies emerged implicating systemic pesticides in the unprecedented decline in bee populations. These pesticides are of a particular concern because they kill sucking and chewing insects by disrupting their nervous system.
Furthermore, “unlike older pesticides that evaporate or disperse shortly after application, neonicotinoids are systemic poisons. Applied to the soil or doused on seeds, neonicotinoids insecticides incorporate themselves into the plant’s tissues, turning the plant itself into a tiny poison factory emitting toxin from its roots, leaves, stems, pollen, and nectar.” These pesticides also persist in the soil for longer than the older generation pesticides.


Uber has caused controversy with regulators and lawmakers across Canada and has not been accepted by any municipality yet. The company cannot be governed as a traditional taxi service and drawing up bylaws that either Uber accepts or taxi drivers accept has proved hard to do.
Uber’s argument from the time it launched in Ontario in 2014 has been that it is a technology company, so should not be subjected to laws set for taxi companies. It is a stance that is actually hard to argue with, simply because Uber is merely a smartphone application that connects passengers with freelance drivers, with the fee paid up front.
If any group is subject to the laws of a traditional taxi service it is the drivers and not Uber, and that is another potential problem. Simply, if drivers are forced into regulations that cost too much to pay for, or are too tough to comply with, then what will be the point of operating for Uber?
The company could be looking to fix this potential future problem and is apparently exploring seriously the idea of autonomous technology. Self-driving vehicles and Uber seem like a match made in tech heaven, a company that offers shared rides and a technology that gets the job done efficiently and does not have to deal with the same taxi-like regulations that a human driver would.
Uber has reportedly already started shopping around for a self-driving solution, but like everybody else the company will have to wait for the market to catch up. Autonomous vehicles are not road-legal yet and are unlikely to be until at least next year. It is also worth taking into account that full autonomy is not expected until 2025 at the earliest.
That means any aspirations Uber has to use self-driving technology are long term goals and the company’s current model will continue for at least a decade. However, it has already been well documented that self-driving cars are coming and 400 million people are expected to be sharing vehicles via autonomous technology by 2030.
It seems that Uber is giving itself a head start.

More than 400 large U.S. military drones crashed in major accidents worldwide between Sept. 11, 2001, and December 2013. By reviewing military investigative reports and other records, The Washington Post was able to identify 194 drone crashes that fell into the most severe category: Class A accidents that destroyed the aircraft or caused (under current standards) at least $2 million in damage.
This graphic is part of 'Hazards Above,' a series published in June 2014.
Not just in war zones
About one-third of the crashes occurred in Afghanistan, but nearly one-quarter happened in the United States during test and training flights. As the Pentagon deploys drones away from traditional combat zones, more accidents are occurring in Africa and other locations.

Crash numbers climbing
The annual number of crashes has risen over the past decade as the military has expanded the frequency of drone missions. The Pentagon says most drone types have become more reliable over time and that the number of crashes per flight hour has steadily decreased.

Inflation, especially high inflation, increases profits as well as the cost of doing business and implies higher demand for products at higher prices and a tight employment market with rising wages. Investopedia reports that inflation, "Is not intrinsically good or bad."Continue Reading
Inflation is present when prices are higher than they were previously. As of 2014, The Board of Governors of the Federal Reserve System reports that an inflation rate of 2 percent is consistent with the Federal Reserve's mandate for maximum employment and stable profitability. This small amount of inflation ensures that the economy is able to grow and that business are profitable enough to maintain and gradually expand workforces.
Inflation above 2 percent can cause an, "inflationary spiral." In this situation, prices are pushed higher by rising consumer demand. Businesses are profitable and hire aggressively to match production with demand. Tight labour markets lead to wage increases. This leads to a higher cost of living with higher rents, home values, consumer prices and prices of raw materials. This represents further increased demand for products and services, which also increases prices, further increasing company profits. These increased company profits again leads to more hiring, which continues to put inflationary pressure on wages and prices. The Business Directory describes this as, "Reinforcing feedback of a vicious circle"Learn more about Economics

An ornamental stone, jade is a name applied to two different silicate minerals. Nephrite is a form of the amphibole actinolite (a mineral that also includes a form of asbestos). The second, the mineral jadeite, is a pyroxene. Nephrite has the formula Ca2(Mg, Fe)5Si8O22(OH)2. Jadeite has the formula NaAlSi2O6. The two are quite similar in appearance and it wasn't until 1863 that the two forms of this gemstone were distinguished.
It is an exceptionally tough material, and was first used for things such as axe heads, knives, and weapons. Later, as other materials could replace jade as a weapons material, it became appreciated for its beauty. Jade has a Mohs scale of Mohs hardness of between 6.5 and 7.0.
Nephrite can be found in a creamy white form as well as a green color, while jadeite shows more color variation. Of the two, jadeite is rarer, and is the form of jade mostly used in Central America. Nephrite jade was used mostly in China, Myanmar and New Zealand.
In White Wolf games, jade can specifically refer to:
- Jade, one of the Five Magical Materials in Exalted
- Jade, a magical substance used by the Dark Kingdom of Jade in Wraith: The Oblivion, and variations such as White Jade and True Jade
- The Jade Caste of the Alchemical Exalted in Exalted
- Jade Shintai, a Kuei-jin Discipline in Kindred of the East
- JaDe Associates in Trinity

Churches too aspired to continuity with the pre-depression world. Presbyterians and Methodists built big brick Colonial complexes; Catholics remained loyal to stone walls and pointed arches.
But commercial buildings were different. Most strove to look modern — though not usually in a Bauhaus way. For the first time in our history, a gulf opened up between residential and commercial architecture. Roadside commercial buildings (major image-setters in this period) were frequently whimsical, more frequently banal. Signs often overshadowed buildings. The orthodox modernism of the State Office Buildings (Fisher, Nes, Campbell, 1957) coldly prefigured Charles Center. High-rise public housing was ballyhooed as futuristic. The Rouse Company and RTKL invented the enclosed shopping mall, (at Harundale, in 1958.)
Exterior View, Courtesy of Church of the Redeemer
Given this tension between modern and traditional, is it surprising that the most successful designs tried to split the difference? The Church of the Redeemer (Pietro Belluschi and RTKL, 1957) has been a favorite since it was built, as have Moore & Hutchins’s buildings for Goucher College.
Perhaps the greatest legacy of this period was not the work of an architect. Formstone, patented in Baltimore in 1940, swept the city’s rowhouse neighborhoods from 1946 to 1954. The average Baltimore street suddenly ceased to look like a legitimate descendant of Georgian London, and Baltimore had a new image.


To understand reverse osmosis, first consider osmosis. Osmosis is the movement of a solvent, such as water, through a semi-permeable membrane to equalize the concentrations of a solute, such as salt, on each side of the membrane. If, for example, unequal concentrations of salt solutions were placed on each side of a suitable membrane, the water would move from the lower concentration side through the membrane to the side with the higher concentration of salt. By applying pressure on the higher concentration side, the process can be reversed, hence reverse osmosis. So reverse osmosis can effectively reduce salt concentrations, and is one of several major approaches used to remove salt from seawater.

World Health Organisation (WHO), established on April 07, 1948, proposed to celebrate World Health Day to focus on different health aspects for the benefit of mankind. From 1950 onward April 07 is celebrated across the world as World Health Day. Every year a topic is chosen with the focus on one aspect of health. For example, in recent years various themes have been chosen, working together for health (2006), invest in health, build safer future (2007), protect health from adverse effects of climate changes (2008). In 2011 it focused on Antimicrobial resistance and its global spread. These are very important aspects to deal with for the good of mankind as a whole. All the participating countries celebrate this day and bring the message to the common people.
The theme for 2012 is ‘Ageing and Health’ to focus on good health that add life to years. Very noble indeed when the aged and old people instead of contributing to enhance wisdom in the families and society feel neglected. World Health Day shall surely add something so as to make the aged and old more useful to our society.
WHO has done a commendable job over the past six decades by taking up various issues. However, it is crystal clear that good food is the first requirement for good health. In recent years junk food has spread like an epidemic across the globe, and the third world nations are the worst hit by them. The food giants have opened their distribution points everywhere and have flouted the norms and do not stick to the health standards. This is virtually equivalent to a chemical war. Will WHO with help of World Heath Day programmes spread the awareness among people to avoid eating the junk food and persuade the food giants not to serve such harmful stuff for the consumption thereby helping the next generation to remain healthy. Prevention is better than cure.
May the health drive by WHO be successful.

The presentation was based on his research and book The Extraordinary Leader : Turning Good Managers into Great Leaders.
Using “The Leadership Tent” as the conceptual framework, Zenger talked about the following five elements of a great leader:
1. Character – The center pole represents the personal character of an individual. It is the core of all leadership effectiveness. A great leader must display integrity and honesty.
2. Personal Capability- This tent pole describes the intellectual, emotional, and skill makeup of the individual. It includes technical and professional expertise, analytical and problem-solving capabilities, ability to create a clear vision and sense of purpose for the organization, and self-development.
3. Focus on Results - This tent pole describes the ability to have an impact on the organization. It means being capable of getting things done, taking initiatives and driving for results.
4. Interpersonal Skills - This tent pole includes all the interpersonal and people skills, such as communicating, inspiring and motivating others to high performance, building relationships, developing others, collaboration and teamwork.
5. Leading Change - This final tent pole focuses on an individual’s ability to produce change within an organization.
Zenger also talked about 10 fatal flaws that consistently lead to leadership failure:
- Not inspiring due to a lack of energy and enthusiasm
- Accepting mediocre performance in place of excellent results
- Lack of clear vision and direction
- Loss of trust stemming from perceived bad judgment and poor decisions
- Not a collaborative team player
- Not a good role model (failure to walk the talk)
- No self-development and learning from mistakes
- Lacking interpersonal skills
- Resistant to new ideas, thus did not lead change or innovate
- Focus is on self, not the development of others


Bed-wetting, or nocturnal enuresis, causes distress among children and young adults, as well as for their parents or caregivers. Researchers at the Assiut University Hospital, Egypt, have revealed a method to reduce the frequency of night time bed-wetting and improve the quality of life for sufferers. They suggest that repetitive sacral root magnetic stimulation (rSMS) can successfully reduce the frequency of night time bed-wetting.
For the study, researchers analyzed 41 patients who were divided into two groups receiving either real magnetic stimulation or a sham stimulation using the same equipment and procedures. Every participant received 10 sessions, five per week. A magnetic stimulator was placed over their sacral vertebrae in the lower back and 15 Hz pulses were applied for 10 seconds on and 30 seconds off.
Lead investigator professor Eman M. Khedr said, "It seems likely that rSMS produced some of its effect in the present patients by a direct effect on bladder control. In the present study rSMS could have increased arousal or enhanced inhibition of neuronal re-uptake of noradrenaline and serotonin."
After the end of the treatment sessions, the average number of weekly nocturnal bed-wetting episodes fell from 5.7 to 0.3 per week for the real group compared to 6.5 to 1.8 per week after sham stimulation. Although the procedure resulted in improvement (placebo effect), the improvement in the real group continued one month later (one per week) whereas the sham group returned to baseline behavior (5.2 per week).
The findings were published in Restorative Neurology and Neuroscience.


Probiotics are the friendly bacteria; live micro organisms that help cure illnesses and maintain good health, particularly good digestive health. This premise has been questioned from time to time – whether probiotics really work.
A recent analytical study answers this question in the affirmative; that probiotics do indeed work ; particularly in the case of health problems such as diarrhea.
The diarrhea infection is a major killer, particularly in the developing world and chief form of treatment for this kind of problem is to prevent the person getting dehydrated by using hydration techniques. This treatment however does not get rid of the infection or shorten its duration.
Probiotics on the other hand are seen to shorten the duration of the infection and actually fight the infection. These friendly microorganisms fight with other infection causing ones and help to shorten the illness.
Many studies have been able to demonstrate this ability of probiotics to shorten the duration of an illness and actually fight infection. When probiotics are administered along with fluids, they shorten the duration of the diarrhea proving that this is a helpful approach to use. Further they were shown to have no adverse or side effects either.


I have talked about alkaline foods but many of you have asked what are acidic foods that can be eliminated from your diet for anyone, not just those with disease or transitioning to the alkaline lifestyle.
What are Acidic Foods?
In the Alkaline lifestyle, foods that are not alkaline are considered acidic and are below 7 in the pH scale. These are the foods that cause disease and allergic reactions to the body yielding an unhealthy environment for disease to grow and bacteria to thrive. These foods have been linked to cancer and heart disease.
Acidic Foods to Avoid
Here is a list of the top ten most acidic foods that should be avoided at all times:
- Dairy products
- Meat and shellfish
- All forms of sugar (including fruits)
- Mushrooms and algae
- Peanut and peanut oil
- Fermented foods (including soy sauce and miso)
Anyone who wants to improve their general health can start avoiding these gradually and adding more alkaline foods to their diet to see results. From loosing weight to improving heart disease, these changes to your lifestyle will make a difference. Many doctors are starting to recommend a vegan lifestyle for heart disease patients. But it’s important to understand that a vegan diet can also be acidic or unhealthy. I was a raw vegan junk food eater and a vegan junk food years ago too. Before the decision to be a vegan became an energy/spiritual path reason, I would not mind eating french fries at a fast food joint, or eating a mushroom burger with fake cheese and drinking a sake bottle. I could still be a vegan, but the choices I was making were not healthy and highly acidic.
The same can be said about eating a raw vegan diet. There are those that eat 30 bananas a day believing that’s healthy because it’s fruit that fell from a tree. The truth is that tropical fruit is acidic and creates a terrible environment for the body. You might as well eat a steak!
Making healthy choices can be difficult but making small steps can be beneficial to your health.


A compound sentence is a sentence containing two or more independent clauses (complete sentences), joined by a coordinating conjunction.
"I went home early" is a complete sentence with a subject (I), a verb (went), a direct object (home), and an adverb (early) which modifies the verb.
The independent clauses of a compound sentence should be related in some way.
Examples of compound sentences:
I went home early but I forgot my assignment book.
- two independent clauses joined by the conjunction 'but'.
I wasn't feeling well so I went home early.
- two independent clauses joined by the conjunction 'so'.
I went home early since it was a half day.
Because it was a half day, I went home early.
- joined by the coordinating conjunctions 'since' and 'because'.
Note that the two independent clauses can be in the reverse order with a comma separating them. The coordinating conjunction can start the sentence.
I went home early and washed my hair.
NOT a compound sentence. The second part of the sentence has no subject of its own.
The conjunction 'and' is joining the compound verb.


1.3.9 Spring and neap tides
The Sun also has an effect on the Earth’s oceans. When the Earth, Moon and Sun are all in a line the lunar and solar tides will add together creating a higher high tide and a lower low tide. This is known as a spring tide and occurs during the full Moon and new Moon. When the Earth, Moon and Sun are at right angles the solar tide will make the lunar tide smaller. This tide is called a neap tide and occurs during the first-quarter and third-quarter phases of the Moon.


Nagasaki atomic bomb survivor Sumiteru Taniguchi dies at 88
A Japanese man who survived the Nagasaki atomic bomb in August 1945 has died of cancer at the age of 88.
Sumiteru Taniguchi was working as a postman on the morning the US dropped the bomb that killed more than 70,000 people.
He became a prominent activist against nuclear weapons and was once seen as a front-runner for the Nobel Peace Prize.
At a ceremony in 2015, he described seeing a sea of fire and people's flesh burning off: "It was hell."
Mr Taniguchi, who was only 16 years old at the time, suffered horrific burns to his back and left arm which took many years to heal.
He was riding his bicycle some 1.8km (1.1 mile) from the epicentre of the explosion.
"All of a sudden, after seeing a rainbow-like light from the back, I was blown by a powerful blast and smashed to the ground," he said at a commemoration ceremony marking the 70th anniversary of the bombing.
"When I woke up, the skin of my left arm from the shoulder to the tip of my fingers was trailing like a rag. I put my hand to my back and found my clothing was gone, and there was slimy, burnt skin all over my hand.
"Bodies burned black, voices calling for help from collapsed buildings, people with flesh falling off and their guts falling out... This place became a sea of fire. It was hell."
The Nagasaki bomb, on 9 August 1945, came three days after the first bomb was dropped on Hiroshima. The city was only chosen after a cloud obscured the original target, Kokura.
The effects of the bomb were instant and devastating. It destroyed a third of the city, killing thousands instantly and condemning more to death from radiation sickness.
Days later, Japan surrendered, ending World War Two, although the necessity of the two bombs has been debated ever since.

The author here reassesses the concept of 'masculinity', and argues that it cannot be seen as an absolute standard, but only as the product of perpetual conflict between competing and unstable models. The argument is sustained by a close reading of the problematic conflict between gendered values in eighteenth-century classical learning. Pope's Homer ensured the continuation of the tradition of using the Iliad and Odyssey to teach privileged boys how to become more 'manly'. This book examines this pedagogy in its socio-literary context, and concludes that Pope's Homer emerges as a relic of the struggle to preserve masculine dignity from the encroachments of feminine values in the text. This knowledge of classical and early modern literature has rarely been brought to bear on gender studies. First published in 1993, it remains a valuable contribution to debates concerning the reception of the Classical tradition.


Extensive but separate bodies of research in education concern the constructs of school climate and school connectedness/belonging. In the interests of advancing a more integrated approach, a new measurement tool is developed– the School Climate and School Identification Measure–Student (SCASIM-St). This scale builds on the Moos (1973) framework which assesses relationships, personal growth, and system management in schools. The social identity approach to group processes (Tajfel & Turner, 1979; Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) is used to extend work on school connectedness and belonging through the inclusion of a measure of social identification. A range of methods across three studies are designed to assess the reliability and validity of SCASIM-St (N = 7209, Australian grades 7–10 students). These include confirmatory factor analysis, test-retest analysis, and convergent validity (Study 1 and 2). Additionally measurement invariance tests for student sub-groups regarding gender, grade level, and non-English language, were employed in Study 3. It also included criterion validity analysis using multilevel models for the key outcome measures of students’ academic achievement, well-being, and aggressive behaviors. All of these analyses indicate that SCASIM-St is an effective measure. Theoretical and practical implications as well as future directions are outlined.


"We watch how your face appears to move as you jiggle your phone by typing. It did surprise us how well it worked" admitted Proffesor Ross Anderson.
Nowadays, when more and people access their banking accounts via their smartphones, the necessity of additional security measures is bigger than ever. The researchers suggest that smartphone users should either use longer, more complex PIN codes or randomize the position of the digits in order to minimize the risk of them falling victims to malicious software. It is also suggested that facial recognition or fingerprint scanning should be used if available.
Earlier this year, another security flaw allowed malicious third-party apps to gather data from the smartphone's acellerometer sensors and use it to guess PIN codes and screen lock patterns. Have you ever experienced any similar security issues with your smartphone and the precious data you store?

NEW 2016 Edexcel Religious Studies GCSE lesson on the importance of Al-Quadr in Islam, following the 'Religion, Peace and Conflict through Islam' unit. The lesson is split into Muslim beliefs on predestination focusing on the universe as a whole as well as relating to human lives in particular. There is a strong focus on using sources of wisdom and authority from the Qur'an and for students to interpret Muslim beliefs based on religious teaching. There is also an exploration of the concept of Free Will in Islam and how this is interpreted differently by divergent Muslims following both the Sunni and Shia traditions of Islam. Students use the Hadith Sahih Al-Bukhari 78:685 as a source of wisdom and authority to suggest if Free Will can be compatible with a belief in predestination.


We have now finished our 'Take one Book' unit based on our text 'Stone Girl, Bone Girl'. We hope the children have enjoyed the unit. As teachers, it has given us a chance to see some of imaginative independent writing the children can produce. Also as part of the unit we have had a go at making our own fossilised objects. These are some pictures from Ash class. Birch classes' are still 'work in progress'!
In science the children have been investigating evaporation and condensation. Ask your child if they can explain this scientific vocabulary.
Next week, as our penultimate week before the Christmas break, we have planned to do some Christmas crafts with the children and in our PSHE lessons we will be exploring 'being different but being the same.' If your child could bring in any small craft bits to help them decorate an individual fish shape, it would be appreciated.
Also a note from Mrs Tizard:
We are outside once a week and the weather has definitely changed and become cold. Please can you ensure your child has suitably warm clothes for P.E including socks! (Quite a few girls wear trainers and no socks) Joggers, sweatshirt, gloves and a beany hat are advisable. Thank you it makes lessons so much easier if the children are warm to start with.
Please continue to support your child with homework (separate email sent).
Have a lovely weekend

Visceral Mobilization is a technique in which the physical therapist gently moves the connective tissue surrounding internal organs, thereby restoring normal movement in the tissues.
How can it help me?
Our bodies are made to move, twist, and turn. As we do these motions, our organs also gently slide over each other. For example, when you twist your trunk to the right, your liver also rotates and slides slightly. In addition, normal movement of the organs in the abdomen also allows for optimal organ function.
Scar tissue and adhesions can cause problems in those who have had abdominal surgery or other trauma. Scar tissue can bind your organs to each other, decreasing their motion which in turn can cause restriction of motion of the joints and surrounding soft tissues. Sometimes an orthopedic problem that is resistant to typical treatments of the joints and soft tissues will clear up with visceral mobilization.

Do Magnets attract metals trough different objects of a seame thickness?
- Alberto Vidal
How well magnets work through different objects depends on the
object and how thick it is. If the object is something that isn't
magnetic at all and doesn't normally stick to a magnet, then it won't
matter exactly what it is. For example, if I have a chunk of glass and
a chunk of plastic, the magnet will act almost the same through either.
So if I were to measure the magnet's strength on the other side (from
the same distance away, since magnets do normally get weaker as you get
farther away), I would see just about the same thing as if I just did
it through air.
I put a piece of iron (sometimes called a "keeper") across the
poles of a magnet, this tends to make the magnetic field stay inside
the keeper rather than extending as far as id did before the keeper was

In professional writing, tone is as essential as content. Because how you approach a topic impacts the reader, maintaining an appropriate and professional tone in writing is vital. Dana Driscoll , author of “ Tone in Business Writing ,” says, “The tone of a message is a reflection of the writer and it does affect how the reader will perceive the message.” The article asks writers to develop the professional tone in their writing by asking the following questions before they write.
- Why am I writing this document?
- Who am I writing to and what do I want them to understand?
Driscoll notes, “A competent writer will match the needs and abilities of [his/her] reader and find the most effective way to communicate with a particular reader.” An important factor in ensuring reader understanding is to write from the reader’s perspective.
- What kind of tone should I use?
After determining purpose and audience, use a confident and sincere writing tone to attract and keep your reader’s attention. “You can feel confident if you have carefully prepared and are knowledgeable about the material you wish to express,” Driscoll says, adding, “It is important to strive for sincerity in tone because without sincerity, politeness can sound condescending.” Because your readers may not know you, creating a sincere and honest presence is crucial.
Managing tone can be difficult but, with practice, you can enhance your professional tone in writing and increase your credibility. If you need help creating a professional tone, contact us for information about our customized onsite workshops or enroll in one of our various online courses .


Preventing Noninfectious Diseases.
Noninfectious diseases can’t be passed from one person to another.
Instead, these types of diseases are caused by factors such as the environment, genetics, and lifestyle.
What are the causes of non infectious disease?
A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.
How can non infectious diseases be prevented?
Effective approaches for large-scale NCD prevention include comprehensive tobacco and alcohol control through taxes and regulation of sales and advertising; reducing dietary salt, unhealthy fats, and sugars through regulation and well-designed public education; increasing the consumption of fresh fruits and vegetables,
What are 5 non infectious diseases?
A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson’s disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer’s disease, cataracts, and others.
What are the prevention and control of non communicable diseases?
Preventing and controlling noncommunicable diseases
- Raise priority accorded to NCDs through international cooperation and advocacy.
- Strengthen national capacity, governance, multisectoral action, and partnerships.
- Reduce the major modifiable risk factors, such as tobacco use, harmful use of alcohol, unhealthy diets, and physical inactivity.

Visiting Arizona’s Montezuma Castle
Arizona, with its arid climate, has many wonderful places of antiquity to visit that have been remarkably preserved.
A wonderful place to visit, and a short hop off the I-17 is Montezuma’s Castle.
From the National Park Service website:
“On December 8, 1906, President Theodore Roosevelt celebrated the passage of the Antiquities Act by declaring four sites of historic and cultural significance as our nation’s first National Monuments. Among these was Montezuma Castle, which the President identified as a place “of the greatest ethnological value and scientific interest.” Although very few original artifacts remained in the structure due to intensive looting of the site, Roosevelt’s decision assured the continued protection of one of the best preserved prehistoric cliff dwellings in North America.
Montezuma Castle National Monument quickly became a destination for America’s first car-bound tourists. In 1933, “Castle A”, a 45-50 room, pueblo ruin was excavated, uncovering a wealth of artifacts and greatly enhanced our understanding of the Sinagua people who inhabited this riparian “oasis” along Beaver Creek for over 400 years.
Early visitors to the monument were allowed access to the structure by climbing a series of ladders up the side of the limestone cliffs. However, due to extensive damage to this valuable cultural landmark, public access of the ruins was discontinued in 1951.
Now, approximately 350,000 people a year gaze through the the windows of the past during a visit to Montezuma Castle. Even 600 years after their departure, the legacy of the Sinagua people continues to inspire the imaginations of this and future generations.”
We have many places that we are dying to tell you about. The places to visit, and the vistas to see are beyond imagination.

If a variable contains NULL value and if you try to do some operation on it. it will throw a null pointer assignment error
We said that the value of a pointer variable is a pointer to some other variable. There is one other value a pointer may have: it may be set to a null pointer. A null pointer is a special pointer value that is known not to point anywhere. What this means that no other valid pointer, to any other variable or array cell or anything else, will ever compare equal to a null pointer. #include
int *ip = NULL;
In general, C does not initialize pointers to null for you, and it never tests pointers to see if they are null before using them. If one of the pointers in your programs points somewhere some of the time but not all of the time, an excellent convention to use is to set it to a null pointer when it doesn't point anywhere valid, and to test to see if it's a null pointer before using it. But you must use explicit code to set it to NULL, and to test it against NULL. (In other words, just setting an unused pointer variable to NULL doesn't guarantee safety; you also have to check for the null value before using the pointer.) On the other hand, if you know that a particular pointer variable is always valid, you don't have to insert a paranoid test against NULL before using it.

A brain teaser for one player.
This cube is made from 27 single cubes. Unfold it to get a winding snake,
and then fold it back into a 3x3 x3 cube.
Hint (sh....) - The first 3 cubes will make the first row for the cube.
Once the shape is unraveled, getting it back into a cube turns out to be much harder than it looks.
A 3 x 3 x 3 cube made up of 27 pieces linked together by a stretchy string.
This dynamic cube is one of our hardest, and also happens to be one of our favorites. The Koncy Puzzle contains six pieces. Nothing connects these pieces to each other, or lets the cube retain its form, besides the unique and unconventional shapes of the pieces themselves. Dismantling this cube is a very complex and gentle affair. It should be done one step at a time, and is difficult in and of itself.
The 6 pieces slide apart and return to a cube. It is important to note the last piece to come apart as it is the last to be inserted as the cube is reassembled.
Composed of 9 pieces. You need to assemble them to a cube, or a dice with red/green dots.
Invented during a physics lecture the Soma Cube brings the fun and challenge of tangrams into the 3rd dimension.
The cube is built from 7 different pieces, creating a 3X3X3 cube. There are 240 different ways to build a solid cube.
There are as many hundreds of shapes to assemble from all the parts. Try to invent your own shapes as well.


Unfortunately, it seems animal agriculture once again cross-contaminated some romaine lettuce. The Public Health Agency of Canada recommends that people in Ontario and Quebec avoid eating romaine lettuce for the time being.
While fruits and vegetables on their own cannot have E. coli, a common source is raw fruits and vegetables that have come in contact with feces from infected animals. Leafy greens, such as lettuce, can become contaminated in the field by soil, water, animals or improperly composted manure.
In addition, a recent study shows that washing contaminated fruits and vegetables is not enough to get rid of the bacteria so we would recommend following the recommendation and avoid romaine lettuce altogether.


In science, we will be talking about the Earth, Sun, and Moon connection. We will specifically be focusing on nuclear fusion, the phases of the moon, and eclipses. HERE is the presentation I will show you on Monday. Below are your vocabulary words that you must study for a quiz on Friday:
nuclear fusion- the process by which nuclei of small atoms combine to form a new, more massive nucleus; the process releases energy
sunspot- a dark area of the photosphere of the sun that is cooler than the surrounding areas and has a strong magnetic field.
eclipse- an event in which the shadow of one celestial body falls on another
phase- the change in the sunlit area of one celestial body as seen from another celestial body
satellite- a natural or artificial body that revolves around a planetYes, that's right! ONLY 5 WORDS! But, don't get too excited...the rest of the quiz will require you to identify the phases of the moon we will talk about on Monday. Here is a picture of the phases you must know:
Over the next two weeks, you will be working on a choice sheet to guide your studies on the Earth, Sun, Moon connection. This choice sheet will be due Friday, March 10th. The 10th is also the day of our final test on these topics.
So, you can see it's going to be a busy, busy, busy week. But, look forward to Friday because we will have a "Drop Everything and Read" event to celebrate Dr. Seuss' Birthday! Rest up this weekend so we can hit it hard on Monday.
See you then,


Gabriella Elanbeck and Rory Clarke, OECD Observer
New York City has one of the highest average population densities in the world, and few other US cities share its concentrated hustle and bustle. In fact, most of them face an entirely different challenge: urban sprawl.
The average number of inhabitants per km2 of populated urban space is actually very low in the US, as our chart shows. So while New Yorkers must grapple with the difficulties that accompany larger numbers of people in limited urban space, such as congestion and high rents, people in low density cities face long commutes and costly public service provision.
The US is not alone. While average population density in the urban areas of OECD countries is high in Korea and Japan, it is low in countries such as Austria and Canada. But even in those countries and cities with high average densities, urban sprawl must be confronted.
People’s lives may suffer, as this scattered and decentralised city growth can lead to environmental damage, social exclusion, and pressures on transportation and public services, as well as high public and private costs. What can policymakers do?
Finding sustainable solutions to reduce sprawl demands rethinking urban space and weighing the private benefits of low density living–my house and garden–against social, environmental and infrastructure costs. Compact cities, which balance dense development patterns, strong public transport linkages, accessibility to local services and jobs, affordable houses and healthy open spaces, can provide an answer.

Hebrew thus started in the 1920s ideologically supported within the Jewish community and officially recognized by the Mandatory government in Eretz Yisrael, as the language for that community and its schools.
The riots (pogrom - farhud) against the Jews of Babylon that broke out in Baghdad in 1942, left a profound impression on the heart of every Jew, and especially the yong ones, who began to find solotions in the form of illegal immigration, mainly to the Land of Israel. The first cell of the underground Zionist movement in Baghdad was established during the second half of 1942. The purpose was to act within the framework of the youth, to learn the reviving Hebrew language, to educate for pioneering Zionism, and for emigration to the Land of Israel (1).
The waves of new immigration who come to the State during the years 1950 - 1952, learned Hebrew informally or in Ulpanim (intensive programs).Younger immigrations (children going to school, or young addults serving in the army), rapidly became Hebrew speakers, but many immigrants maintained the use of their languages. In many cases, the children became the teachers of their parents in their first attempts to speak Hebrew (2).
Since then. the Hebrew that became the official language of the State of Israel, replaced and eradicated the Arabic Baghdadi language spoken by the Jews of Babylon, who arrived in Israel within the framework of the mass emigration to Israel.

The Importance of Cannabinoids
Cannabinoids found in plants are called phytocannabinoids, and those found in the cannabis plant account for most of its benefits. They are naturally occurring, with CBD (short for cannabidiol) making up about 40% of plant resin extract. Our human body also produces cannabinoids, called endocannabinoids, which interact with the body’s endocannabinoid system (ECS) to restore chemical balance.
Our ECS is a complex cell-signaling system, like a main switchboard within our bodies, that influences cardiovascular, nervous, and endocrine systems, along with impacting our skin conditions, appetite, sleep patterns and immunity. The cannabinoids from the help plant work to stimulate our ECS and enhance our overall quality of life.


Lesson 1 (from Chapter 1, Guest and Daughter)
In Chapter 1, Lila introduces the fieldwork she expected to do as an anthropologist. The objective of this lesson is to discuss the work of an anthropologist.
1) Research: Look up these terms and write definitions for each: anthropologist, ethnography, and anthropological fieldwork. Write the answers to these questions: What are different types of anthropology? Is ethnography a branch of anthropology? In what types of anthropology is fieldwork important? What would be some things an anthropologist might do while conducting fieldwork? What type of training would an anthropologist have before doing fieldwork?
2) Partner discussion: Divide the class into groups of 2-3. Was Lila an anthropologist? Would she be considered a cultural anthropologist? Why? Where did she wish to do fieldwork? What were the two subjects of study that she pursued during her fieldwork? Did Lila have to change the focus of her subject after she established her...

Ultrastructure of mature spermatozoa in the lumen of the spermatheca and middle vas deferens of Paratelphusa hydrodromous (Crustacea)
AbstractMature spermatozoa of P. hydrodromous are spherical or ellipsoidal, composed of an acrosome surrounded by a cup shaped nucleus. The acrosome is divided into a distal apical cap and an acrosomal vesicle, which is enclosed in the cup shaped nucleus. The apical cap is raised in its middle to form the apical cone. Below the apical cap is the subcap region. The acrosomal vesicle has a central canal, which encloses dense tubules. A thin inner layer, middle acrosomal rays layer and an outer acrosomal vesicle layer surrounds the central canal. Radial arms are absent. Along the posterior region of the spermatozoa are posterior median processes. Within the lumen of the mid vas deferens, spermatozoa are seen encased in oval or spherical spermatophores. Spermatophores are without distinct lining membranes. In the spermatophore lumen spermatozoa exist free or two to three of them tightly packed to form a unit. Each unit is surrounded by an electron-lucent halo, embedded in a moderately dense spermatophore ground substance. The spermatozoa are seen embedded in a flocculent material possibly the seminal plasma. There was hardly any structural difference between spermatozoa present in the lumen of the spermatheca and those present in the mid vas deferens (MVD).
KEY WORDS: Spermatheca, middle vas deferens, ultrastructure, crabs, spermatozoa.

All the advancements in technology that were being made were not perfect and still are immune to making mistakes. On January 28, 1986 America was shocked by the destruction of the space shuttle Challenger, and the death of its seven crew members.
As is expected in a field of work that's exploratory and uncertain such as the National Aeronautics and Space Administration (NASA) space program, any tragedy that occurs often makes inside employees, government officials, and even the general public, wonder why it's necessary at all to continue when the consequences are so grave.
On the morning of Feb. 1, 2003, space shuttle Columbia broke apart roughly 40 miles above the earth's surface in the sky over the state of Texas. On this return flight to earth, seven astronauts died aboard the shuttle, six of which were American plus one Israeli astronaut. Five of the astronauts were men and two were women.
Four of these people had never even flown in space before. NASA has not yet discovered the reason for this tragedy although there has been speculation.
This is not the first time that a shuttle has been lost. It is the second time in seventeen years. This recent disaster has brought back memories of the Challenger shuttle and its demise in 1986 upon take off.
Tragedies such as the Columbia and the Challenger that occurred seventeen years ago can partly be blamed for lack of funding and cutbacks on employees in order to conserve as much money as possible.
Yet these are not the only tragedies that have taken place. Vostok (12 April 1961): on the very first manned space mission, the instrument module initially failed to detach from the descent module following retrofire. It only separated when the heat of re-entry burned through the straps which attached...


There are a number of images of Jesus as a child in St Swithun’s church as figures, statues or in a picture, rather than in stained glass.
The reredos or back screen in this Chapel has the figure of Mary with a small boy in front of her. The left hand panel has a carved scene representing the time when Jesus, aged about 12, was lost by his parents. They eventually returned to the Temple and found him deep in discussion there. He said to his parents ‘Wist ye not (did you not know) that I must be about my Father’s business?’ These words are inscribed under the carved picture.
This reredos was a gift from St Margaret’s Convent and came from the Chapel of St Michael’s School in 1938 (according to the Church Guide of 1946). When the old organ, which also came from the Convent, in 1888, was removed in the 1930s, this Chapel was created.
Down the centuries people have identified with Christ as a fellow human being and with Mary as a Mother, and have created images to help their prayers. During the twentieth century, a number of pictures of the young Jesus were given to St Swithun’s, in stained glass, as carved figures or statues and created in embroidery.


Meningococcal disease is a serious illness caused by a bacteria. It is a leading cause of bacterial meningitis in children 2-18 years old. Meningitis is an infection of fluid surrounding the brain and the spinal cord. Meningococcal disease also causes blood infections. About 2,600 people get meningococcal disease each year in the U.S. 10-15% of these people die, in spite of treatment with antibiotics.
Meningococcal vaccine is recommended for all children at their routine 11 year health exam. It is also recommended for college freshmen living in a dorm.
- Soreness and swelling at the injection site
- Guillain-Barre Syndrome (very rare)


Within the first two stanzas of T.S. Eliot's "The Waste Land" (1922), there are five different European languages, three references to historical events contributing to WWI, and no less than eight literary allusions, ranging from Christian holy books to medieval poetry to Romantic German opera. However, Eliot gives barely any assistance to his readers for recognizing these references or understanding why he makes them.
As a result, Modernist poetry (like Eliot's) has long been considered some of the most difficult literature in the English language, meant only for the most adept and keen readers. It also contains some of the most brilliant, beautiful, and influential works ever written. This course will help turn you into just such a reader and reveal to you the brilliance and beauty locked within these enigmatic poems. Along the way, you will also learn more about the history and politics of the early 20th century than you thought possible. Authors we will analyze include Thomas Hardy, W.B. Yeats, Langston Hughes, T.S. Eliot, e.e. cummings, and Marianne Moore.
By completion of this course, successful students will be able to:
- Identify poetic form (e.g. meter, rhyme, consonance and assonance) and how form relates to meaning in poetry
- Describe the historical and political contexts of the late-19th/early-20th centuries in Europe and North America, and how these influenced poetry
- Define how Modernism was influenced by previous artistic movements, and how later artworks were influenced by it
- Identify most influential names and works of the Modernist period
- Identify stylistic characteristics of various Modernist movements (e.g. Dadaism, Imagism, Harlem Renaissance)
- Read and critique any poem like a pro!


|The Beautiful Tibet|
|Last Updated ( Tuesday, 19 February 2013 )|
All of modern China, including Tibet, is considered a part of East Asia. Historically, some European sources also considered parts of Tibet to lie in Central Asia. Tibet is west of the Central China plain, and within mainland China, Tibet is regarded as part of , a term usually translated by Chinese media as "the Western
section", meaning "Western China".
Yarlung Tsangpo River
Buddhist flags in Tibet Mountains
Tibet is often called the "roof of the world."
Tibet has some of the world's tallest mountains, with several of them making the top ten list. Mount Everest, at 8,848 metres (29,029 ft), is the highest mountain on earth, located on the border with Nepal. Several major rivers have their source in the Tibetan Plateau (mostly in present-day Qinghai Province). These include Yangtze, Yellow River, Indus River, Mekong, Ganges, Salween and the Yarlung Tsangpo River (Brahmaputra River). The Yarlung Tsangpo Grand Canyon, along the Yarlung Tsangpo River, is among the deepest and longest canyons in the world.
Tibet has been called the "Water Tower" of Asia, and China is investing heavily in water projects in Tibet.
The Indus and Brahmaputra rivers originate from a lake (Tib: Tso Mapham) in Western Tibet, near Mount Kailash. The mountain is a holy pilgrimage site for both Hindus and Tibetans. The Hindus consider the mountain to be the abode of Lord Shiva. The Tibetan name for Mt. Kailash is Khang Rinpoche. Tibet has numerous high-altitude lakes referred to in Tibetan as tso or co. These include Qinghai Lake, Lake Manasarovar, Namtso, Pangong Tso, Yamdrok Lake, Siling Co, Lhamo La-tso, Lumajangdong Co, Lake Puma Yumco, Lake Paiku, Lake Rakshastal, Dagze Co and Dong Co.The Qinghai Lake (Koko Nor) is the largest lake in the
People's Republic of China.

Starting in the mid-1990s, Africa embarked upon its longest period of sustained, positive per capita income growth since the 1960s. This growth recovery has made a dent in poverty and holds out hope that a number of African countries may reach the Millennium Development Goal targets for poverty and food security (MDG 1), if not by 2015, then within the following few years. Agricultural growth has been, and will remain, key to reducing poverty and hunger in Africa. To significantly reduce poverty, Africa needs to sustain, broaden, and accelerate its recent growth performance and boost its investments in agriculture. The recent spike in global food prices represents an opportunity that could support further agricultural sector growth in Africa. The unfolding financial crisis, on the other hand, could have the reverse effect, especially if it leads to lower investments in the sector.


Main Article Content
The study was conducted in two agro-ecological zones of La Trinidad, Buguias and Atok, Benguet. The objectives of the study were to determine the physical and chemical properties of soils of agricultural farms; to determine the pesticide residues in soils and plants; and to determine toxic heavy metals in soils of agricultural farms. The two agro-ecological zones comprised of mid-mountain zone with elevation ranging from 1,100 to 1,500 meters above sea level represented by La Trinidad and Buguias, Benguet and high mountain zone with 1,600 to 2,000 meters above sea level elevation represented by Atok, Benguet.
For mid-mountain zone represented by La Trinidad, Benguet for wet season sampling and Buguias, Benguet for dry season sampling, most of the soil samples collected showed favorable values of bulk density, porosity, pH, organic matter, available phosphorus and exchangeable potassium for crop production. On the other hand, pesticide residue analysis on soil samples showed that only Cypermethrin and Chlorpyrifos have values higher than the maximum allowable concentrations. Toxic heavy metals like Mercury and Lead have values lower than maximum residual limit. Likewise, only Chlorpyrifos was detected in plants but its value is below the maximum allowable concentration.
For the high-mountain zone represented by Atok for wet and dry season sampling, the results of the analysis showed that values of bulk density, porosity, pH, organic matter, available phosphorus and exchangeable potassium are also found favorable for crop production. For pesticide residue analysis in soil, the samples were found to have residues of Dieldrin, Endosulfansulfate, Cypermethrin, Chlorotalonil, Cypermethrin and Deltamethrin. However, only Chlorothalonil and Cypermethrin were found to have values higher than the maximum allowable concentration. Mercury and Lead were found to have values below the maximum residual limit. No pesticide residues were detected in crops.


Gravity’s Ghost and Big Dog brings to life science’s efforts to detect cosmic gravitational waves. These ripples in space-time are predicted by general relativity, and their discovery will not only demonstrate the truth of Einstein’s theories but also transform astronomy. Although no gravitational wave has ever been directly detected, the previous five years have been an especially exciting period in the field. Here sociologist Harry Collins offers readers an unprecedented view of gravitational wave research and explains what it means for an analyst to do work of this kind.
Collins was embedded with the gravitational wave physicists as they confronted two possible discoveries—“Big Dog,” fully analyzed in this volume for the first time, and the “Equinox Event,” which was first chronicled by Collins in Gravity’s Ghost. Collins records the agonizing arguments that arose as the scientists worked out what they had seen and how to present it to the world, along the way demonstrating how even the most statistical of sciences rest on social and philosophical choices. Gravity’s Ghost and Big Dog draws on nearly fifty years of fieldwork observing scientists at the American Laser Interferometer Gravitational Wave Observatory and elsewhere around the world to offer an inspired commentary on the place of science in society today.


Paraceraurus exsul (Beirich 1846) - Russia - Ordovician
Paraceraurus exsul from the Asery Level, Vilpovitsy Quarry, Near St. Petersberg, Russia.
Dates to the Middle Ordovician Period - In the region of 465 million years old.
Beautifully preserved fossil trilobite from this location, these delicate specimens take many hours of preparation in order to free them from the matrix. This trilobite is a good size at 10.5 cm in length by 7.0 cm wide (sizes include spines) on a matrix 15 cm x 11 cm. The hard calcite exoskeleton shows up nicely against the lighter limestone matrix. The spines likely acted as a defence against predators, the hypostome is also visible.
Please note that the spines are fragile and care should be taken when handling the fossil.


How To Make Paper Bags
Here are some simple instructions on how to make an origami paper bag. It is a miniature version, of course.
Hi. This is how you make an origami bag. You can use a larger sheet for this if you want to make a more usable bag.
Turn the sheet or paper over and forward the two diagonals. One, open it back up and two, we're now going to forward that point to the middle and make a crease. Turn it over and repeat.
Unfold the fold you just made. We're now going to fold this line to meet that fold, like so and also going to repeat on this side. So, again, this line will meet that middle fold.
Now, we're going to fold the entire model in half. We're going to make the handle now. To make the handle, we actually have to make a cut.
And I'm just going to draw the line so you can see it. So, we're going to cut along that line. So, technically, this is not origami.
This is paragami, cut paper. So we're just going to cut along that line. There.
Open the model back up. And this triangle flap, you'll fold down onto itself and repeat on the other side and then you'll open up the bag. And you have yourself a little bag.
That was how you make an origami bag. .


In 1900, astronomer Joseph Lunt made a discovery: Peering through a telescope at Cape Town Observatory, the British–South African scientist spotted this beautiful sight in the southern constellation of Grus (The Crane): a barred spiral galaxy now named IC 5201.
Over a century later, the galaxy is still of interest to astronomers. For this image, the NASA/ESA Hubble Space Telescope used its Advanced Camera for Surveys (ACS) to produce a beautiful and intricate image of the galaxy. Hubble’s ACS can resolve individual stars within other galaxies, making it an invaluable tool to explore how various populations of stars sprang to life, evolved, and died throughout the cosmos.

Noise occurs when random pixels appear in your photograph, and it can give your image a grainy effect. When it's excessive and unintentional, noise can be distracting for viewers and can detract from the impact of your photos.
In this short video tutorial from my course on creating the pixel-perfect photograph, you are going to learn about the causes of noise in your photos, how to decrease it, and how to avoid introducing excessive noise yourself. You'll also learn why it is best to save noise correction until the very end, and the appropriate levels of pre-sharpening your image.

Raw image data from a digital camera needs processing by a computer to turn it from a simple binary record to a beautiful visual image. While profiles and presets can do a good job, it always takes some human intervention to get things just right.
In the full course, From RAW Capture to the Pixel-Perfect Photograph, you will learn a solid creative and technical foundation for working with images, and you will practice a processing methodology that takes the guesswork out of post-processing.
Although this course is delivered in Adobe Lightroom, the principles and methodology learned here are also easily transferable to similar software, such as Adobe Camera Raw and Capture One Pro.
You can also get a head start with your Lightroom post-production work by downloading some of the useful Lightroom presets from Envato Market.
