Improved Windows for Cold Climates In this paper the possibilities of improving the energy performance of windows in cold climates are exam-ined. The background for using windows with improved energy performance is the need to reduce the en-ergy consumption in buildings. Since the heat loss through windows often represents half the total heat loss from houses, much energy can be saved by developing and using better windows with respect to energy performance. The main purpose of having windows in houses is that they provide daylight and view, but windows also provide solar gain that can be utilized as a contribution to the space heating in the building. Therefore the windows also have a positive influence on the energy balance of buildings. To evaluate the possibilities for developing better windows with respect to energy performance when used in Nordic and arctic climates, seven different window types have been examin...

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...

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...

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...
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...

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...

Passive houses OK, so let´s get started. Good afternoon everyone, my name is Kristiina, I´m a second year student here at Tallinn University of Technology and I´m standing here in front of you to talk about the ,,passive houses I will inform you about their magnitude and percentage nowadays and also talk about the potential difficulties that might appear when building a passive house". But I´ll start off by giving you an overview of the term. The definition of a passive house is based on its extremely low energy need. Passive houses consume less than a quarter of energy required for a standrard building, as a result reducing its ecological footprint. So it´s a ultralow energy building which requires little energy for space heating or cooling. Sounds appealing right? Sustaining the earth for our future generations and also in the long run benefit from living there with paying lower tax...

Project Plan Bellacoola The Bella Coola Development Study merges community requirements for the envisioned facility and the alternative approaches to building on the Bella Coola Northern Pointe site. Consultants’ reports regarding structural considerations and tree evaluation are included for their continued application to the problem. An effort has been made to work with the full extent of space requirements currently voiced by the Western Division Management Center and the Bella Coola Village Organization. Other organizations were queried to form the basis of judgment in determining the overall need. This recognizes that as the program development progresses, tenant requirements may change, but the essential square footage and cubic limitations for a below grade structure will remain. In addition, it has been envisioned that jointly required facilities would be available for all organizations to use on a shared basis, utilizing mova...

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....
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...

Estonian University of Life Sciences Report on Soil Microflora By Katrin Vares Tartu 2013 Introduction The purpose of this report is to define soil microflora and establish the importance of it. Since the microorganisms clearly play an important role in preserving the balance of life, the next objective is to look into factors that influence this balance. Natural conditions and cultural impact could be considered as the variables that correlate the most with the activity and composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail. Definition, composition and importance of microflora Saunders Comprehensive Veterinary Dictionary (2007) cited by the online medical dictionary (2013) defines living microorganisms as that small that they can be seen only with a microscope and that maintain a more or less constant presenc...

Funktsionalism - Under the influence of Darwin, the school of functionalism stressed the role of conciousness and behavoior in adapting to the enviroment. Pragmatism tõe kriteerium on tegevuse/idee kasulikkus. Inimene ise saab enda elu/iseloomu/tuju muuta, vaba tahe, kuidas soovib käituda. Igasugused uskumused on kasulikud ja väärt, kui need on efektiivsed William James - oli pragmaatik kes... uskumine vabasse tahtesse teadvuse voog / stream of consciousness - teadvust ei saa elementideks jagada vaid on pidevalt muutuv ja personaalne - peegeldab indiviidi kogemusi, eesmärk on tagada kohanemine keskkonnaga. Teadvus on personaalne, ei saa jaotada, pidevalt muutuv, valiv, kohaneb keskkonnaga Rakenduspsy kujunemine. Uurimistehnikate laiendamine (kasuliku teabe leidmine inimese kohta).

1. Ökoloogiateaduse uurimisobjektid Ecology (from Greek: , "house"; -, "study of") is the scientificstudy of the relation of living organisms to each other and their surroundings.[1] Ecology includes the study of plant and animalpopulations, plant and animal communities and ecosystems. Ecologists study a range of living phenomena from the role of bacteria in nutrient recycling to the effects of tropical rain forest on the Earth's atmosphere. Autökoloogia on ökoloogia haru, mis tegeleb organismide keskkonnanõudluste ja keskkonna- suhete uurimise ja kirjeldamisega. Demökoloogia ehk populatsiooniökoloogia (Schwerdtfeger 1963: 1314) on ökoloogia haru, mis uurib organismide populatsioone ja nende keskkonnaoludest johtuvat dünaamikat. Sünökoloogia on ökoloogia haru, mis tegeleb liikidevaheliste suhetega ökosüsteemides, organismide mitmeliigiliste koosluste (ehk biotsönooside) ...
