Argumentative presentation: Estonia does need a nuclear power station Good evening. My name is Margus and I will be talking to you about why does Estonia needs a nuclear power station. My talk consists of 3 parts: the current situation, renewables and how can nuclear power save Estonia from an energy crisis. My talk will last for 2-3 minutes and questions can be asked at the end. Power consumption is increasing exponentially in all civilised countries. Estonia's coal based power generation is becoming obsolete in the near future. The question arises : "Where will the future generations get the energy that they need?". First of all, in the current year, the power consumption reached the highest of all tomes in February. Most of the energy shortage was covered by energy brought from Lithuania. Energy was produced there from gas imported from Russia. That is not a reliable source of energy that can scale. In add...
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...

Nuclear power produces around 11% of the world's energy needs, and produces huge amounts of energy from small amounts of fuel, without the pollution that you would get from burning fossil fuels. Nuclear power costs about the same as coal, so it's not expensive to make. Although not much waste is produced, it is very, very dangerous. It must be sealed up and buried for many thousands of years. For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult. Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster. One of the most feared disadvantages of nuclear energy is the potential for weapons. Each year, every nuclear reactor is capable of making enough plutonium to build over thirty nuclear bombs. Nuclear plants must be secured well enough to prevent this material from falling into the wrong hands. ...

Chernobyl disaster Outline • What happened? • Elimination of the consequences • The Exclusion Zone • Conclusion • Quiz • Reference list What happened? • The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe. • The Chernobyl disaster was the worst nuclear power plant accident in history in terms of cost and casualties, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011). • The battle to contain the contamination and avert a greater catastrophe ultimately involved over...
Name at least 3 renewable energy sources. What consequence might there be if we use non-renewable energy too much? Which energy technology is the world's fastest growing? With what name is renewable energy also known as? Light Heat Electricity Generated from natural resources. Doesn't harm the environment. Can't be replenished Most of our energy. May cause global warming. Wind energy is the fastest growing. Most renewable energy comes from the sun. Hydroelectric energy is the oldest and largest source. Renewable energy a.k.a "green" energy. Thank you for listening! We use energy every day. It surrounds us in different forms, such as light, heat, and electricity. Our bodies use the energy stored in molecules of substances like carbohydrates and protein to move, breathe, grow, and think. We also use energy to do work and to play. Humans have invented thousa...
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...
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 three months and several further deaths later. Acute radiation syndrome was originally diagnosed in 237 people on-site and involved with the clean-up. Of these, 28 people ...
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...

The Cataclysmic Death of Stars Republished from the pages of National Geographic magazine 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 twi...

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...

BARRIERS TO DISTRICT HEATING DEVELOPMENT IN SOME EUROPEAN COUNTRIES Abstract District heating (DH) offers low primary energy demand, high security of supply and small CO 2 emissions. Barriers to DH in the UK, Ireland, France, Romania and the Czech Republic have been compiled through publications and interviews. DH systems require large investments, have negative initial cash flow and long payback time, which obstructs financing. One actor should control DH from source to consumption. If the value chain is fragmented, contracts are required between the links. It increases risks and financing costs, like in the UK and Ireland, where DH is not established. There are few multi- family houses with central heating and it is expensive to build DH networks in built areas. Most French DH systems are operated according to long-term concessions by companies that sell electricity and gas. No strong actor provid...
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...

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...

Psychology Gleitman Blood flow in the brain during different activities: the rate of blood flow is measured by special radiation counters that are placed at various points of the skull and that monitor radiation from mildly radioactive gas injected into the bloodstream. Blood flow pattern depends on what the patient does ( different pattern is found when person is reading aloud, yet another when he watches a moving light and so on). Ambiguous sights and sounds: The way ambiguous figures are perceived often depends on what we have seen just before. For example, if we are first shown an unambiguous figure of a rat, the ambiguous picture will be seen as a rat. If we are first exposed to an unambiguous face, we see the ambiguous figure as a face. What holds for visual patterns also holds for language. Many utterances are ambiguous. If presented out of context, they can be undestrood in several different ways. For exam...

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to 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 ...
Public International Law is a system of law, different from domestic law. Why is this system unique? Usually law regulates relations between people, people and the state etc, PIL regulates relations between states. Thats why PIL is important for international relation students. PIL influences the life of everybody, it doesn't regulate people directly but indirectly (through the decisions of the states), because it's everywhere. It's like air. E.g. when you want to send a letter to Brazil, you put a stamp from your own country and send it from your post office and the letter gets delivered. Why is this so easy, because there are certain international conventions that regulate postal services. E.g. traffic signs are almost the same everywhere, why? Because of certain int conventions that require the states to have more or less unified traffic signs. States apply international regulations to national regulations and they ...

By then, Ghana the former Gold Coast had been independent for three years under the great Osagyefo Kwame Nkumah. It was a time for celebrating Africa’s coming of age, as more and more African countries received their independence either from Britain or France. It was especially a poignant time for Africa, as then British Prime Minister Harold McMillan articulated his now famous “winds of change” sweeping Africa. We had high hopes for Africa, for the Black race, that the insidious imposition of foreign rule on us, the looting of Africa’s natural resources by our colonial masters accorded us would be things of history. That is more than forty years ago. Unfortunately, the promise of independence has not been fulfilled. Today, Africa has become more desolate; th...
