the fusion of nuclei heavier than iron absorbs energy; vice- versa for the reverse process, nuclear fission. In the simplest case of hydrogen fusion, two protons have to be brought close enough for their mutual electric repulsion to be overcome by the nuclear force and the subsequent release of energy. Nuclear fusion occurs naturally in stars. Artificial fusion in human enterprises has also been achieved, although not yet completely controlled. Building upon the nuclear transmutation experiments of Ernest Rutherford done a few years earlier, fusion of light nuclei (hydrogen isotopes) was first observed by Mark Oliphant in 1932, and the steps of the main cycle of nuclear fusion in stars were subsequently worked out by Hans Bethe throughout the remainder of that decade. Research into fusion for military purposes began in the early 1940s, as part of the Manhattan Project, but was not successful until 1952
Foreword Bridging rivers, gorges, narrows, straits, and valleys always has played an important role in the history of human settlement. Since ancient times, bridges have been the most visible testimony of the noble craft of engineers. A bridge can be defined in many ways, but Andrea Palladio, the great 16th century Italian architect and engineer, hit on the essence of bridge building when he said "...bridges should befit the spirit of the community by exhibiting commodiousness, firmness, and delight." In more practical terms, he went on to explain that the way to avoid having the bridge carried away by the violence of water was to make the bridge without fixing any posts in the water. Since the beginning of time, the goal of bridge builders has been to create as wide a span as possible which is commodious, firm, and occasionally delightful

pioneering astronomer. A nearby supernova--within a few light-years--would bathe the Earth in lethal radiation. Yet the legacy of supernovas is as close as our own bodies. The carbon in our cells, the oxygen in the air, the silicon in rocks and computer chips, the iron in our blood and our machines--just about every atom heavier than hydrogen and helium--was forged inside ancient stars and strewn across the universe when they exploded billions of years ago. Eager to understand our origins and, in some cases, simply wild about things that go bang, astronomers have been struggling for decades to understand why stars that shine peacefully for millions of years suddenly blow up. Lately they've had two big breaks. One is a revelation about potent blasts of high-energy gamma rays that come from distant points in the heavens. For decades astronomers have puzzled over
3.53.9 Lethal to salmonids, although acclimated roach can survive for longer 3.03.4 Most fish are killed within hours at these levels Environmental effects Very obvious environmental effect of acid rain is the loss of fish in acid sensitive lakes and streams. Loads of fishes are not able to survive in acidic water. There are 2 ways acid rain effects lakes and streams: chronic and episodic. The first one is long-term process and this acidification is result from years of acidic rainfall. Episodic, on the other hand, is rapid change sudden jump in the acidity of water. Acid deposition may influence forest vegetation and soils. It removes soil nutrients such as calcium and magnesium from soils in high elevation forests. Acid rain may also help weaken natural defenses of some trees, making them more vulnerable to some diseases and pests. Acid rain

Plus, renewable resources are often located remote areas and it is expensive to build powerlines to the cities where they are needed. The use of renewable sources is also limited by the fact that they are not always available (for example, cloudy days reduce solar energy, calm days mean no wind blows to drive wind turbines, droughts reduce water availability to produce hydroelectricity). The production and use of renewable fuels has grown more quickly in recent years due to higher prices for oil and natural gas, and a number of State and Federal Government incentives, including the Energy Policy Acts of 2002 and 2005. The use of renewable fuels is expected to continue to grow over the next 30 years, although we will still rely on non-renewable fuels to meet most of our energy needs. trends Consumption Total renewable energy consumption increased by 478 trillion Btu or 7 percent between 2005 and 2006 to 6,922 trillion Btu
The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the atmosphere and downwind. Two Chernobyl plant workers died on the night of the accident, and a further 28 people died within a few weeks as a result of acute radiation poisoning. The April 1986 disaster at the Chernobyl nuclear power plant in the Ukraine was the product of a flawed Soviet reactor design coupled with serious mistakes made by the plant operators. It was a direct consequence of Cold War isolation and the resulting lack of any safety culture. The accident destroyed the Chernobyl 4 reactor, killing 30 operators and firemen within
thick deposits usually are formed as the result of a secondary sedimentary deposing process. Clay deposits are typically associated with very low energy depositional environments such as large lakes and marine basins. (slide 5) Clays exhibit plasticity when mixed with water in certain proportions. When dry, clay becomes firm and when fired in a kiln, permanent physical and chemical changes occur. These reactions, among other changes, cause the clay to be converted into a ceramic material. Because of these properties, clay is used for making pottery items, both practical and decorative, and construction products such as bricks, wall and floor tiles. Depending on the content of the soil, clay can appear in various colors, from a dull gray to a deep orange-red. Clay in Estonia (slide 6) There are 3 basic types of clay in Estonia. Firstly from Cambrian era the blue clay, which has

It was not until the 18th century that the name Lai also started to appear. In 1872, when the street names were being fixed, Lai remained the sole name of the street. 4 1 Lai Street / 4 Nunne Street A good example of Neo-Renaissance and early Art Nouveau styles combined is Lai Street 1, the present Youth and Puppet Theatre, erected at the beginning of the 20th century as the Nobility Club. The three-storey building replaces two medieval properties. In 1784 an amateur theatre began playing in a house situated in the same place and soon became a professional German City Theatre. The famous German writer August von Kotzebue (1761-1819), the life and soul of the theatre, lived in Tallinn for several long periods. (Otto von Kotzebue, the son of August von Kotzebue, accompanied explorer Adam Johann von Krusenstern on his Journey around the World of 18031806.) Estonian was heard
Roman armies were recalled from Britain to defend Rome itself. Once they had left Anglo-Saxons invaded and settled in Britain. They were farming people who preffered to live outside towns. For a while London probably lay in ruins, but it eventually developed again, partly because of its position on the river was good for trading. The Tower of London There is more of London's history in the Tower than anywhere else in London. It is the oldest surviving building in the capital. The Tower of London was begun by William the Conqueror in 1078 as a castle and a palace but even before the site had been used by the Romans and Anglo-Saxons. The tower comprises not one, but 20 towers, the oldest, the White Tower, dates back to the 11 th Century. The Roman stone wall, parts of which can still be seen on the territory of the Tower, may have been a small Roman fort near the river. The White Tower, called so on account of the white Caen stone Brought from

Tsar; the barons were restored their former privileges. In 1870 a railway line was opened from St. Petersburg to Tallinn. Tallinn grew into a major port and an industrial centre. Estonians became conscious of their national identity. Tartu was the centre of the movement of national awakening. On 24 February 1918, Estonia was proclaimed an independent democratic republic. Tallinn developed into a modern European capital. A period of prosperity followed, but independence only lasted for 20 years. During World War II Estonia was occupied by both German and Russian invaders, and Tallinn suffered heavily. The bombing of the city by the Soviet air forces on 9 March 1944 left over 20,000 people homeless. During the Russian occupation which followed (and which lasted for five decades) attempts were made to Russify the local people. Large scale industry was developed in Tallinn, workers were resettled from Russia and new blocks of flats sprang up on the outskirts to provide

Tallinn, the capital city of the Republic of Estonia and of the Harju county, is a town in North Estonia on the coast of the Gulf of Finland. It has nearly half a million inhabitants and covers an area of almost 160 sqkm. It is also an important economic and cultural centre and one of the main ports in the Baltic States. Tallinn is one of the oldest cities on the Baltic Sea. It is unique for its well-preserved architecture from the 13-15 centuries. In contrast to the ancient town-walls and towers, Tallinn of today offers modern hotels, restaurants, sport and cultural centres. Every five years national song and folk dance festivals take place in Tallinn. The yachting regatta of the 1980 Moscow Olympic Games was held at Pirita. History Tallinn means in English "Danish town". The place is believed to have been settled by Finno-Ugric people about 2500 BC. It was first marked on a map of the world by the Arab geographer al-Idrisi in 1154

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. However, in recent years, significant efforts have been made towards their development as feasible military technology. For example, in the late 2000s, the U.S. Navy tested a railgun that accelerates a 3.2 kg projectile to hypersonic velocities of approximately 2.4 kilometres per second, which is about Mach 7. In addition to military applications, railguns have been proposed to launch spacecrafts into orbit; however, unless the launching track was particularly long, and the acceleration required spread
Together they are known as Anglo-Saxons. They were farming people who preferred living outside towns. For a while London probably lay in ruins, but it eventually developed again, partly because its position on the river was good for trading. In 1666 most of the City of London was destroyed in the Great Fire of London. London Bridge The home of the London Bridge is the Thames River, and a bridge has existed on the spot for at least the last 2000 years. The first bridge on record was constructed by the Romans, and since then many bridges have risen at the hands of various empires. London Bridge today remains one of the most popular tourist attractions in Britain as well as an icon for the City of London. London Bridge history records the building of a wooden bridge by the Romans about 2000 years ago. Historians suspect that the location was chosen for its relatively convenient access to the
loudly. What I don't begin to know is the ideal breakdown, according to age, of reading, listening to instruction, and working or hands-on time. What about technology in excess? Before the age of printing and cheap paper, comparatively few people could become learned. Now, theoretically, our electronic age makes learning easier than ever. Well, technology is indisputably better. We can store and retrieve data much more efficiently. We can communicate in a flash. But still, at the basic level, we must be well grounded -- we must possess common sense, civil manners, frank discussion skills, reasoning abilities, and moral fiber. It is possible to be a technological genius, say a computer nerd, without social skills or civil conscience. I'd rather have as a neighbor an illiterate janitor with an easy-going, friendly disposition. Hence, I value what we might call character more than specialist knowledge from an antisocial person. God knows we want
Sydney Opera House Introduction The Sydney Opera House is a multi-venue performing arts centre in Sydney. It was conceived and largely built by Danish architect Jorn Utzon, opening in 1973. The Sydney Opera House was made a UNESCO World Heritage Site on 28 June 2007. It is one of the 20th century's most distinctive buildings and one of the most famous performing arts centres in the world. Contrary to its name, the building houses multiple performance venues. The Sydney Opera House is among the busiest performing arts centres in the world, hosting over 1,500 performances each year attended by some 1.2 million people. It provides a venue for many performing-arts companies. It is also one of the most popular visitor attractions in Australia, with more than seven million people visiting the site each year, 300,000 of whom take a guided tour.

until the current day is irrational and dangerous. Theoretical justification of torture The utilitarian view that a political leader should allow torture to rescue civilians’ lives is justified by that this would result in maximum happiness for the greatest number of people. It is said that in case of a moral dilemma there is never the possibility of 2 complete justification. Torture is illegal but if human lives can be saved, it is worth it. This disregards the act itself and only looks at the result (Driver, 2014). Hedonism supposes that a decision is ethically correct if the consequence brings maximal satisfaction to the individual. Eudemonism replaces the word satisfaction by happiness. The difference between the two words is that satisfaction usually is short- term and focuses more on the senses

become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. 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.

Edinburgh Castle is an ancient stronghold which dominates the sky-line of the city of Edinburgh from its position atop Castle Rock. It is Scotland's second most visited tourist attraction. Human habitation of the site is dated back as far as the 9th century BC. As it stands today though, few of the castle's structures pre-date the Lang Siege of the 16th century, with the notable exception of St Margaret's Chapel, the oldest surviving building in Edinburgh, which dates from the early 12th century.As with all castles, Edinburgh's fortress has been a centre of military activity. As an ancient fortress Edinburgh Castle is one of the few that still has a military garrison, albeit for largely ceremonial and administrative purposes. The New Barrack Block is now home to the official headquarters of the Royal Regiment of Scotland and 52 Infantry Brigade, as well as home to the regimental museum of the Royal
medium. Then it is not the light but the "content" (or what is really another medium) that is noticed. The message of the electric light is like the message of electric power in industry, totally radical, pervasive, and decentralized. For electric light and power are separate from their uses, yet they eliminate time and space factors in human association exactly as do radio, telegraph, telephone, and TV, creating involvement in depth. A fairly complete handbook for studying the extensions of man could be made up from selections from Shakespeare. Some might quibble about whether or not he was referring to TV in these familiar lines from Romeo and Juliet: But soft! what light through yonder window breaks? It speaks, and yet says nothing. In Othello, which, as much as King Lear, is concerned with the torment of people transformed by illusions, there are these lines that bespeak Shakespeare's intuition of the transforming
