Written by Ron Cowen March 2007 Ever since he was a teenager, Stan Woosley has had a love for chemical elements and a fondness for blowing things up. Growing up in the late 1950s in Texas, "I did everything you could do with potassium nitrate, perchlorate, and permanganate, mixed with a lot of other things," he says. "If you mixed potassium nitrate with sulfur and charcoal, you got gunpowder. If you mixed it with sugar, you got a lot of smoke and a nice pink fire." He tested his explosive concoctions on a Fort Worth golf course: "I screwed the jar down tight and ran like hell." "kaboomWoosley", now an astronomer at the University of California at Santa Cruz, has graduated to bigger explosions--much bigger. Woosley studies some of the most powerful explosions since the birth of the universe: supernovae, the violent deaths of stars. The universe twinkles with these cataclysms. They happen every second or so, usually in some
geothermal heat--which are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. While there are many large-scale renewable energy projects and production, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.Kenya has the world's highest household solar ownership rate with roughly 30,000 small (20100 watt) solar power systems sold per year.

With the passage of time, paper was first invented in China and later mushroomed in the rest of the world. The above inventions were worth mentioning to interpret the fact that how man moulded himself in accordance with his needs. As the need arose, man came up with new ideas, new thoughts, and forcefully pushed his mind to run on that particular line of action. Even in the modern era, man has been found to observe the same behavioral patterns. Some years ago, TB and cancer were regarded as incurable diseases, man conducted massive research on them and finally came up with effective solutions. Whether it is the old age or modern era, man has been found too efficient to satisfy his needs and has set numerous examples of it. No matter whether it was a political issue, scientific concern, or even day-to-day chores of life man has reacted in a flexible mood to create a way for himself whenever he realized his needs
In all cases, absorption appears to be limited to cell layers immediately adjacent to the point of contact. Entry of formaldehyde into the blood (i.e., systemic absorption) occurs to a very limited extent, if at all. ENVIRONMENTAL FATE In reviewing the fate of formaldehyde in the environment, it should be noted that the environmental factors that influence the bioavailability to humans of formaldehyde from contaminated air, water, or plant material have not been studied. Air Formaldehyde is removed from the atmosphere by direct photolysis and oxidation by photochemically produced hydroxyl radicals. Formaldehyde absorbs ultraviolet (UV) radiation at wavelengths of 360 nm and longer; therefore, it is capable of photolyzing in sunlight. A half-life of 6 hours has been measured for photolysis in simulated sunlight. There are two photolytic pathways, one producing H2 and CO, and the other producing H and HCO radicals
(1) the Orthodox emancipation agenda (1600-1700), (2) the Russian nation building agenda (1700-present), (3) the scientific agenda (1860-present), (4) the Marxist agenda (1917-1989), (5) the Eurasian agenda (1920-1935), (6) the cybernetic agenda (1953-1975). Russian language Russian language is an East Slavic language and an official language in Russia, Belarus, Kazakhstan, Kyrgyzstan and many minor or unrecognised territories. It is an unofficial but widely spoken language in Ukraine and Latvia, and to a lesser extent, the other post-Soviet states and former members of the Eastern Bloc. Russian belongs to the family of Indo-European languages and is one of the four living members of the East Slavic languages. Written examples of Old East Slavonic are attested from the 10th century and beyond. It is the most geographically widespread language of Eurasia and the most widely spoken of the Slavic languages

Methane leaks from landfills are an ongoing problem, as is the production of biogas in poorly maintained compost piles, manure lagoons, and outhouses. Spontaneous fires and explosions caused by build-ups of gas have been recorded in many regions of the world, illustrating a major problem which needs to be confronted by waste management companies. When this gas is trapped, however, it can be made useful, instead of just being a nuisance. Trapped biogas can be used to power stoves for cooking and heating, in addition to other applications. By trapping the gases, people can prevent methane from reaching the atmosphere, thereby reducing degradation caused by methane gas. The ability to turn waste products into something which can be utilized is also rather convenient, especially in developing countries, where available resources may be limited. Furthermore, by turning biomass into biogas, people can address
The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-,
Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients. FIND OUT 5 WAYS HOW TO STOP POLLUTION. 2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth surface causing melting of polar ice caps, rise in sea levels and also flash floods, excessive snow or desertification. FIND OUT 5 WAYS HOW TO STOP GLOBAL WARMING. 3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food
pollutants. In addition, dioxins which were released into the environment many years ago are still contributing to current exposure. Even very small dioxin concentrations can cause negative effects on the environment and on human health, in particular on the most vulnerable groups like children. Human health effects include impairment of the immune system, the nervous system, the hormonal system and the reproductive functions. Dioxins are also suspected of causing cancer. How Are We Exposed to Dioxins? Although formation of dioxins is local, environmental distribution is global. Dioxins are found throughout the world in the environment. The highest levels of these compounds are found in some soils, sediments and food, especially dairy products, meat, fish and shellfish. Very low levels are found in plants, water and air. Most of us receive almost all of our dioxin exposure from the food we eat:

Kinetics and metabolism The substance can be absorbed into the body by inhalation, through the skin and by ingestion, also as a vapour. The mean lethal dose of aniline may be between 15 and 30 grams. In case of short-term exposure the substance is irritating to the eyes and the skin. The substance may cause effects on the blood, resulting in the formation of methaemoglobin. Exposure at high levels may result in death. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood, resulting in formation of methaemoglobin. Tends to accumulate in the body, especially in bladder. Often leads to bladder cancer. Aniline was tested on animals, but in mice was observed no increase in tumour incidence, in rats, it produced fibrosarcomas, sarcomas and haemangiosarcomas of the spleen and peritoneal cavity. 4. Behavior in the wild Not found in nature
study specific biological correlates of behavior using invasive techniques (removing or scarring brain tissue). Prior to the development of modern technology, one of the most common ways to study the brain was case study. Often case studies provide researchers with a situation that they could never ethically reproduce in a laboratory. One of the most famous case studies of how brain damage can affect behavior is the study of Phineas Gage by Dr John Harlow. Gage was in a serious accident, where a metal pole pierced his skull and brain. Luckily he survived, losing vision in his left eye. He had no difficulty with speech or language, but the balance between his intellectual abilities and emotional control had been destroyed. He became highly agitated and irrelevant, often impatient and rude. Study to his frontal lobe provided evidence that the brain affects personality and social behaviors. Discuss ethical considerations related to research studies at the biological level of
So it is a common heritage of mankind. It was prohibited to make any new claims on it or enlarge existing claims on it (these were proclaimed as frozen ones). Antarctic is a peaceful zone, any military activities are prohibited, inter alia, any measures of military nature, establishment of military bases, tests of equipment and weapons, fortification. It was permitted to use military equipment for scientific research/purposes. Prohibited to do nuclear explosion and to dispose any nuclear waste. Member states can compose expeditions (under the organizing state's jurisdiction) and polar stations (under the state's jurisdiction) and they are under the jurisdiction of the state, but not the territory. After the expedition countries should give the research to the other member states. All member states have the right to check if all provisions to the treaty are all fulfilled in good
deciphered from it is called placode, a shortening of "plain code." Code that has been transformed is called encicode, from "enciphered code." To pass a plaintext through these transformations is to encipher or encode it, as the case may be. What comes out of the transformation is the ciphertext or the codetext. The final secret message, wrapped up and sent, is the cryptogram. (The term "ciphertext" emphasizes the result of encipherment more, while "cryptogram" emphasizes the fact of transmission more; it is analogous to "telegram.") To decipher or decode is for the persons legitimately possessing the key and system to reverse the transformations and bare the original message. It contrasts with cryptanalyze, in which persons who do not possess the key or system— a third party, the "enemy"—break down or solve the cryptogram. The difference is, of course, crucial
the advancement in spacecraft related research. The purpose of this essay is to explain what a railgun is and how it works along with a little history and the recent advancements in railgun related science. 3 1. What a railgun basically is A railgun is an electrically powered electromagnetic projectile launcher and a large electric circuit, made up of three parts: a power source, a pair of parallel rails and a moving armature. Along the pair of parallel conducting rails a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. Railguns have long existed as experimental technology but the mass, size and cost of the required power supplies have prevented railguns from becoming practical military weapons.
results come only after great efforts. Sensitivity in my integrated meaning is broad, covering literally the senses, so that deaf and blind people are less sensitive, as well as people whose senses work perfectly, but whose receptivity or thought processes are blunted for whatever reason. A person can be insensitive in one way, such as blind, and extraordinarily sensitive in another way, such as in hearing. It is also possible to be so ultra-sensitive that the result is disadvantageous. I expect no argument in asserting that a normal sensitivity is a healthy, indispensable ingredient for optimal education. Sensitivity can be heightened or blunted by education. It is intertwined with curiosity. An ideal education affords numerous and varied opportunities for students to touch, see, smell, listen, hear; to spark their curiosity. When I was a child the things that pleased me were largely other than the plants which have earned me a living as an adult
At the heavier end of the range, paraffin wax is an alkane with approximately 25 carbon atoms, while asphalt has 35 and up, although these are usually cracked by modern refineries into more valuable products. The shortest molecules, those with four or fewer carbon atoms, are in a gaseous state at room temperature. They are the petroleum gases. Depending on demand and the cost of recovery, these gases are either flared off, sold as liquified petroleum gas under pressure, or used to power the refinery's own burners. During the winter, butane (C4H10), is blended into the petrol pool at high rates, because its high vapor pressure assists with cold starts. Liquified under pressure slightly above atmospheric, it is best known for powering cigarette lighters, but it is also a main fuel source for many developing countries. Propane can be liquified under modest pressure, and is consumed for just about every application relying on petroleum for
Landeskirche in the Estonian and Livonian territories, the Lutheran church long maintained a de facto predominance. The most important organ of Baltic German local government was the Diet, consisting of all the noble families who had been `selected' in a list of the eligible. Although jealously guarding their privileges, the knighthoods still never became entirely closed. Between sessions of a Diet, the legislative power of the knighthoods belonged to the Council of the Diet. The towns were governed by the Town Councils, which supplemented their ranks from among the representatives of merchants and lawyers. The citizens and the inhabitants of a town did not coincide -- most of the population had no civic rights. The lower class mainly consisted of Estonians. While an special status secured the supremacy of the Baltic knighthood and the German upper classes
maker. He could not find anyone to teach him, so he went to London. After a year James returned to Scotland where he became mathematical instrument maker to Glasgow University. He also made musical instruments organs, violins, flutes and guitars. Then he began to work on steam engine. He built a new type of engine, with a separate consider and an air pump. It was great discovery. Watt's engine became the basics of industry. He invented a copying machine. The unit of electric power or activity was named 'a watt' after him. He retired when he was 64. His last invention was a machine for copying sculptures. He had many friends. He died in 1819. A monument was erected to him. 4) THANKSGIVING In the United States, the fourth Thursday in November is called Thanksgiving Day. On this day Americans give thanks for their blessings they have enjoyed during the year. Thanksgiving is usually a family day, celebrated with big dinners and happy reunions

1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two. There are many propulsion arrangements for motor vessels, some including multiple engines, propellers, and gearboxes. Large engines drive electrical generators that provide power for the ship's electrical systems. Large ships typically have three or more synchronized generators to ensure smooth operation. The combined output of a ship's generators is well above the actual power requirement to accommodate maintenance or the loss of one generator. 1.1.1)Diesel engine The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the heat of compression to initiate ignition and burn the fuel that has been
managing to unite the Anglo-Saxons and Danes at the beginning of 11th century. Medieval England After defeating the Anglo-Saxon King Harold at the Battle of Hastings in 1066, William of Normandy (who became William I, also called William the Conqueror) introduced the Norman feudal system, rewarding his French-speaking followers with land in return for their continued support. French remained the language of the upper classes and administration until the 14th century. The power of these Norman Barons gradually increased and during the reign of the Plantagenets began the challenge the King's absolute power, which resulted in King John being forced to sign Magna Carta in 1215. It consisted of long list of limitations to the King's power and it gave more power to the origins of Parliament. The origins of Parliament are to be found in the reign of John's successor, Henry III. It
Or how you want a sandwich when you are hungry. Craving for tobacco is much stronger. These changes in the brain and body make nicotine highly addictive. Other addictive drugs of abuse, including heroin and cocaine, cause the same changes in the brain. While inhaling a cigarette, smokers are pulling more than nicotine into their lungs. Tobacco smoke contains more than 4,000 chemicals. Besides nicotine, the most dangerous chemicals in cigarette smoke are tar and carbon monoxide. Tar causes lung cancer, emphysema, and bronchial diseases. Carbon monoxide causes heart problems; smokers are at high risk for heart disease. Smokers also have a dulled sense of smell and taste, reduced stamina for exercise and sports, and they smell of smoke. After smoking for a long time, smokers find that their skin ages faster and their teeth turn brown or discolored Each year, nearly half a million Americans die from tobacco use. One of every six deaths in
assignment of recording rights, but they would remain friends and work together again. Between 1968 and 1972, Bob and Rita Marley, Peter McIntosh and Bunny Livingston re-cut some old tracks with JAD Records in Kingston and London in an attempt to commercialize The Wailers' sound. Livingston later asserted that these songs "should never be released on an album ... they were just demos for record companies to listen to." The Wailers' first album, Catch A Fire, was released worldwide in 1973, and sold well. It was followed a year later by Burnin', which included the songs "Get Up, Stand Up" and "I Shot The Sheriff". Eric Clapton made a hit cover of "I Shot the Sheriff" in 1974, raising Marley's international profile. The Wailers broke up in 1974 with each of the three main members going on to pursue solo careers. The reason for the breakup is shrouded in conjecture; some believe that there were

The environment in realtion to mobility/transport in Europe Air pollution is problem all over the world. Through some pollution comes from these natural sources, most pollution is the result of human activity. The biggest causes are the operation of fossil fuel- burning power plants and automobiles that combust fuel. Combined, these two sources are responsible for about 90% of all air pollution in the United States. All kind of pollutions can lead us to serious health problems. For example, air pollution is increasingly being cited as the main cause of lung conditions such as asthma - twice as many people suffer from asthma today compared to 20 years ago. Every year, 3.2m Europeans are diagnosed with cancer - the most common cause of death after heart disease
thought that the loud explosions would protect them. It was not long before the ancient Chinese realised the military potential of these devices and primitive rockets were used to repel a Mongol invasion in 1232 AD. Word of these new amazing weapons quickly spread around the world and soon rockets were being used in military operations in North Africa and Europe. During the 15 th and 16th centuries they were widely used in naval battles to set fire on enemy ships. Around this time they also started being used for more peaceful purposes again. In the 16th and 17th century Europe fireworks displays using rockets became a very popular form of public entertainment. In the late 18th century the British army suffered two serious defeats at battles in Seringapatam, in India. The main reason for these defeats was that the Indian prince, Haidar Ali's army included a corps of rocket throwers
