Nuclear Power: A Burden or a Blessing? Today, when the pollution of Earth is an important matter, people are trying to find economic solutions to produce power. This is where the necessity of nuclear power plants comes in question. Nuclear power plants are a cheap way to generate electricity but it also brings a lot of pollution that is much more radioactive and toxic than, for example, coal waste. But if we are looking at the facts, burning coal pollutes the Earth much more than nuclear power plants because more waste is generated. CO2, which is released from burning coal, is the main cause of global warming. Nuclear waste is collected and hidden in rocks or under ground, where it won't face the environment. However we shouldn't depend on nuclear energy as Uranium reserves are ending, especially when the world population is increasing and so is the demand for energy. There is Uranium in seawater, but gettin...

Environmental problems Many environment problems are caused by human actions. 1. Air pollution. Use public transportation instead of your own when going to work. Air pollution is also drastically reduced by conserving energy. It is the little things, like switching off fans and lights when you are not at home. Electricity causes the burning of large amounts of fossil fuels, which in turn pollute the air. Solar power is a fantastic solution. Now that solar radiation is at a climactic peak, we can reap power from the sun using solar panel systems. These range from home systems to larger scale systems powering entire communities and cities. 2. Deforestation. While individuals can rarely have a personal impact on the deforestation rate, there are other things you can do. Discourage deforestation and thus environmental degradation by reusing plastic a...

Natural resources-our treasure Natural resources are land or raw materials like minerals, fluids, gases, organic matters and also woods, groundwater, animals and so on, in other words it's everything that human hasn't created. These resources are also used in industry. We get natural resources from the environment. Many of them are essential for our survival while others are used for satisfying our wants. Renewable resources: Some natural resources can be reproduced within a few years or decades. These are called renewable resources. Solar radiation, wind and hydroelectricity, are perpetual resources that are in no danger of a lack of long-term availability. Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be carefully managed to avoid exceeding the worlds capability to displace them. Solar energy is the energy derived directly from the Sun...
Environment and renewable energy 1. How can we help bring about a change in behavior? * Renewable energy is the sun and the water that people use, but not yet so widely. Required on all homes, various stations, hypermarkets solar panels to use the potential energy, the stock of which is not completed within 5 billion years. * Renewable sources such as wind and solar are intrinsically unsuited to meeting the demand for continuous, reliable supply on a large scale – which comprises most demand in developed countries. The criteria for any acceptable energy supply will continue to be cost, safety, and security of supply, as well as environmental considerations. 2. How can we encourage sustainable development? * To encourage you in the following way. To allocate money for the construction of such stations to States that are unable to pay for expensive power plants. Permanent sponsorshi...
Water creates energy Eduard Kamenski 11a form The world uses energy from many different sources, such as: hydroelectric power, nuclear power plants, solar energy, and wind generated power. There are positive and negative aspects of each source, but which source of energy is best? My opinion is that the best source of energy is water and I'll bring up some facts why do I think so. Hydroelectric power is currently the world's largest renewable source of electricity. It accounts for six percent of the worldwide energy supply or about fifteen percent of the world's electricity. Water has been found to be a major source of energy. Water power is utilized at present mainly as hydro-electricity. It is produced from moving water and from falls with the help of turbines and dynamos. Hydro-electricity has acquired great significance as a source of energy in the country in the present times and is being put to different uses. The following are the...
1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a l...

Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan Causes · It is caused when sulfur dioxide and nitrogen oxides are released into the air. In the atmosphere they re...

GLOBAL WARMING Global warming is the observed century-scale rise in the average temperature of Earth's climate system. Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850. More than 90% certain that most of global warming was being caused by increasing concentrations of greenhouse gases produced by human activities.In 2010 that finding was recognized by the national science academies of all majo...

Green Technologies - innovation and climate change sustainagility Scientists can examine ice, but they cannot tell out anything about our future. Even if scientist has lived thousand years he won't be able to do it. The graph in video shows that the amount on carbon dioxide rises and then rises the temperature, but it is not so, it is exactly the opposite. One way to save energy is to build better buildings, because big headquarters are built to last only for 30-35 years. Building them up and pulling them down needs a lot of energy and about 30% of building energy is spent on it. It is thought that if in Tokyo 50% of all roofs are green it will save 1 million dollars a day of Tokyo businesses in cooling costs. Street light use 5% of energy, but it can be reduced to 2%. Usual TVs should be replaced with Plasma TV, because it saves energy more. By driving electic-car, it is possible to save energy a...

The Romans came to Britain nearly 2000 years ago and changed our country. The Romans lived in Rome, a city in the centre of the country of Italy .One day, some years before Jesus Christ was born, the Romans came to Britain. First invasion - Caesar's first raid In August 55 B.C. (55 years before Jesus was born) the Roman general, emperor Julius Caesar invaded Britain. He took with him two Roman legions. After winning several battles against the Britons in South-East England he returned to France. Second invasion - Caesar's second raid In 54 B.C. Julius Caesar came to Britain again landing at Walmer near Deal in Kent. This time he brought with him five legions (30,000 foot soldiers) and 2,000 cavalrymen (horse riders). This time the Romans crossed the River Thames. After more fighting, the British tribes promised to pay tribute to Rome and were then left in peace for nearly a century. Third and final invasion In 43 A.D. (43 years after Je...
1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 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....

English literature is one of the oldest literatures in Europe; dates back to the 6th century AD. Oral literature, i.e. not written down, spread from person to person. In 449 AD Anglo-‐Saxon tribes invaded England – beginning of the Anglo-‐Saxon period in English literature. The first form of literature was folklore, carried by scops and gleemen, who sang in alliterative verse (a kind of simple poetry). Prose developed much later. The first form of recorded English literature was the epic Beowulf, which was produced sometime near the end of the 7th and beginning of the 8th century. It has no ...
Dear Sir/Madam, I am writing in the hope that you can help me with a problem regarding a camera that I have bought recently. On 24 April, I purchased a Canon digital SLR camera from a duty-free shop at Freetown Airport on my way from Freetown to Wondercity. The camera cost $599, and I paid for it by credit card. When I arrived at my hotel in Wondercity almost 24 hours later, I discovered that the box which contained the camera did not include the battery, and the space in the box for the charger was empty. I am now in Wondercity, and I am not returning to Freetown, so I need to get the missing parts here. I would be grateful if you could arrange for the parts to be sent to me. I attach a copy of the receipt for your information. I look forward to hearing from you. Yours faithfully, Introduction This report looks at the dietary habits of twenty students in their final year at Freedonian Secondary School. The report is bas...

All about High Tech High tech is technology that is at the cutting edge--the most advanced technology currently available. There is no specific class of technology that is high tech--the definition shifts over time--so products hyped as high tech in the 1960s would now be considered, if not exactly low tech, then at least somewhat obsolete. This fuzzy definition has led to marketing departments describing nearly all new products as high tech. Economy Because the high-tech sector of the economy develops or uses the most advanced technology known, it is often seen as having the most potential for future growth. This perception has led to high investment in high-tech sectors of the economy. High-tech startup enterprises receive a large portion of venture capital. However, if, as has happened in the past, investment exceeds actual potential, then investors can lose all or most of their investment. High tech is often viewed as high risk, but...

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and perme...

Education Education is so multifaceted that it is difficult for me to know where to begin discussing it, or how to prioritize the many factors. Relaying my own experience is easy: I had a standard classroom approach, supplemented by inordinate reading. In only the briefest and least memorable instances did I receive any individual tutoring. Education is commonly thought of as the job of schools. Adults cry "educate our children!" Everyone has opinions about the best way to do the job. It is of urgent importance, and all the numerous factors are much studied, debated, and new (or old) ideas continually tested or retested. Some people say "it's as simple as . . . " and then name their pet peeve or passion. My view is not of an education specialist, but of one who loves sharing what I learn, and owes much to educators. Since I don't have an educational theory neatly worked-out, nor an outline of my perceptions, my intent is to addr...
Programmeerimine keeles PHP Andrei Porõvkin Tartu Ülikool (2009) 1 1.1 Üldinfo Alguses oli interneti lehed omavahel seotud staatiliste html dokumentide süsteemina, aga selleks, et mingis dokumendis muutusi teha oli vaja lehti failisüsteemis käsitsi muuta. Kahjuks selline staatiline mudel ei jõua kiirelt muutuva kaasaegse maailma progressile järgi. Seega võeti kasutusele dünaamiline mudel. Dünaamilise mudeli korral ei hoita serveris staatilisi html lehte vaid neid genereeritakse selleks spetsiaalselt välja töötatud programmidega, mis serveril töötavad. Antud kursuse jooksul tutvume klient-server arhitektuuriga, installeerime enda arvutisse veebiserveri ja php interpretaatori ning saame baasteadmisi serveripoolsest keelest PHP. Kursuse teemad on pühendatud ainult PHP keelele (väljarvatud seitsmes teema), aga see ei tähenda, et sellest piisab suure ja eduka veebilehe loomiseks. Mahuka infosüsteemi e...
