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.
Hello My name is JOHN SMITH and I am here to talk about Hydroelectricity. Global energy use has risen by 70% since 1971 and continues to increase at the rate of 2% per year. There are many scenarios for future demand. One solution would be to use more hydropower. In 2005, renewable energy represented one-fifth of total power generation. Hydropower is the most advanced of the renewable and represents 87% of this production. 160 countries all over the world are using hydropower. Five countries make up more than half of the world's hydropower production. Those countries are: Brazil,Canada, China, Russia and the USA. (Production) *Most of the energy comes from the potential energy of dammed water driving a water turbine and generator. In this case the energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow.

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
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

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.
Margit Tepner k0848752 Sustainability aspects of biofuels 1. Introduction The literature review will discuss the sustainability aspects of biofuels. Food production will be the main concern as it is the most debated issue, but other aspects, such as land use change and water consumption will be also considered as they are essential aspects in the biofuels sustainability criteria. The review will discuss the viability of biofuels based on the current technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels when they break through to the industrial scale. 2. The scale of biofuels production 2
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.

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. 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

and severe climate. Canada extends across the continent of North America, from Newfoundland on the Atlantic coast to British Columbia on the Pacific coast and northward into the Arctic Ocean. Canada shares land borders with the United States to the south and north-west. Canada is a land of great variety. Towering mountains, crystal-clear lakes, and lush, green forests make Canada's far west a beautiful region. Farther inland, fields of wheat and other grains cover Canada's vast prairies. Thes fertile farmlands contrast vividly with the Arctic wastelands to the north. Most of the largest towns and industrial areas lie near the Great Lakes and the St Lawrence River in central Canada. In the east, fishing villages and sandy beaches dot the Atlantic coast. Across the country, Canadians experience many different landscapes from rolling plains and mountains to the cold tundra of the north.

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-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together. The outer flowers are the ray
thermostation with accuracy ± 0.1 °C using a water or air bath. Although thermostating in liquid is more efficient, air flow of about 10 m / s are suitable for heat dissipation in HECE to 5 W / m. Air temperature control is technically feasible easier, so almost everywhere this method is used. High voltage power source HECE requires a source of direct current with voltageabout 30 kV and a current strength about 200 to 300 uA. For good reproducibility of migration time voltage fluctuation should be within ± 0.1%. It should be possible to change the polarity of the source. Under normal conditions, EOF is directed toward the cathode. In this case, the sample injection is

of scale or pace or pattern that it introduces into human affairs. The railway did not introduce movement or transportation or wheel or road into human society, but it accelerated and enlarged the scale of previous human functions, creating totally new kinds of cities and new kinds of work and leisure. This happened whether the railway functioned in a tropical or a northern environment, and is quite independent of the freight or content of the railway medium. The airplane, on the other hand, by accelerating the rate of transportation, tends to dissolve the railway form of city, politics, and association, quite independently of what the airplane is used for. Let us return to the electric light. Whether the light is being used for brain surgery or night baseball is a matter of indifference. It could be argued that these activities are in some way the "content" of the electric light, since they could not exist without the electric light. This fact
Some may have come on woven reed rafts, or boats, across the Pacific from Asia and various islands. Still others may have crossed the ice fields that once connected Europe and North America. The Inuit, who live in the high Arctic, were probably the last to arrive. 4. How were the terms `Métis' and `half-breed' traditionally used? Métis French-speaking and Catholic. Half-breed English-speaking and Protestant. Half-breed is a term used almost exclusively by the federal government throughout the late nineteenth and early twentieth centuries. Race served to distinguish between populations or groups when describing an individual who was of mixed ethnicity or "blood." The term has historically been used to identify people that are now often called `Métis' in Canada. Many people back then considered the `half-breed' to be a degenerate, inferior sort of human.

The cultural bond may be ethnic or racial or geographical, based on gender, or due to shared beliefs, values, and activities. 2. Culture- beliefs, behaviors, objects, and other characteristics common to the members of a particular group or society. 3. A unitary state- a state governed as one single power in which the central government is ultimately supreme and any administrative divisions (subnational units) exercise only powers that their central government chooses to delegate. The majority of states in the world have a unitary system of government. 4.

The territory of Estonia covers 45,227 km² and is influenced by a temperate seasonal climate. The Estonians are a Finnic people closely related to the Finns, with the Estonian language sharing many similarities to Finnish. The modern name of Estonia is thought to originate from the Roman historian Tacitus, who in his book Germania (ca. AD 98) described a people called the Aestii. Similarly, ancient Scandinavian sagas refer to a land called Eistland, close to the German term Estland for the country. Early Latin and other ancient versions of the name are Estia and Hestia. Until the late 1930s, the name was often written as Esthonia in most English speaking countries. Estonia is a democratic parliamentary republic and is divided into fifteen counties. The capital and largest city is Tallinn. With a population of only 1.4 million, it is one of the least-populous members of the European Union. Estonia was a member of the League of Nations from 22

histories give it but passing mention. Churchill's great history of World War II has been cleaned of every single reference to Allied communications intelligence except one (and that based on the American Pearl Harbor investigation), although Britain thought it vital enough to assign 30,000 people to the work. The intelligence history of World War II has never been written. All this gives a distorted view of why things happened. Furthermore, cryptology itself can benefit, like other spheres of human endeavor, from knowing its major trends, its great men, its errors made and lessons learned. I have tried in this book to write a serious history of cryptology. It is primarily a report to the public on the important role that cryptology has played, but it may also orient cryptology with regard to its past and alert historians to the sub rosa influence of cryptanalysis. The book seeks to cover the entire history of cryptology
