Why no t to purc has e a hybrid? · Even tho hybrids seem to be the solution to "go green"and save the enviroment, its a long way from it. · Hybrids are not zero-emisson vehicles. · High tech parts use various rare alloys and metals. · Batteries use nickel which travels 10000 miles before manufactured into a battery. · High tech parts need to be recycled separetly.(2 motors, alloys, computer parts) · Batteries can still oppose a treat to life in the case of a car accident. · Producing a hybrid takes more energy than the car can save during its lifetime. Why no t to purc has e a hybrid? · Hybrids are more expensive than traditional cars, to buy and to keep running. · Lifetime of a hybrid car is shorter.

Avastamise ajaloost: Looduslikult esinevat nikli-vase sulamit kasutati 2000 e. Kr Hiinas. 235ndal aastal e. Kr vormiti Hiinas nikli sulamist münte. Kaevurid, kes otsisid hõbedat puutusid tihti kokku sellise madalasordilise metalliga. Kaevurid nimetasid selle punaka värvusega maagi Kupfernickel'iks. Nimi tuleneb saksa keelest ja tähendab kuradivaske. Kupfer = vask, nickel = kurat. Seda nime kasutasid Ülem-Saxoni kaevurid sissekandes 1654. aastal. Esimest korda esines see nimi trükitud raamatus 1694. aastal, kui kirjeldati mittevajalikke mineraale ja maake. Aga ainele seal kirjeldust ei olnud. 1751. aastal Rootsi mineraloog Axel Fredrick Cronstedt eraldas puhastamata rauamaagi ühes Rootsi kaevanduses. Ta tuvastas selles uue pool-metalli. Paar aastat hiljem ta avastas, et see pool-metall on identne ühe talle Saksamaalt saadetud Kupfernickeli metallilise osaga

Kalle puges maja vundamendi alla peitu ja varsti raadiosaatjaga kutsus abi, kõne katkes kuna ta võeti kinni. Nad pidasid põgenemisplaane, kuid nägid et lennuk mis pidi Rasmuse välismaale viima tuli 2 tundi varem kohale. Kalle läks lennuki alla ja lõikas seal mõned asjad läbi, Peters võttis Rasmuse ja Rasmus karjus ei taaha ei taha! Nickel läks süd härdaks ja haaras Rasmuse ja pages metsa. Peters läks järgi ja kõlas lask. Nicke oli haavatud ja Rasmus nuttis ja kallistas teda ka Nicke nuttis. Ta viidi haiglasse . Rasmus läks isa juurde. Ka politsei jõudis kohale ja võttis lapseröövlid kinni. Lapsed sõidsid tagasi ja Rasmus liideti pühalikult valgeks roosiks. Alguses oli natukene igav aga aina põnevamaks läks vahel oli isegi kurb.

Võimalik, et venelaste peod kolivad lihtsalt Kremli silme alt ära. Veebruaris keelas Medvedev oma personalil minna ilma loata välismaale puhkama, pärast seda kui riigi ametnikke ühes Prantsuse suusakuurortis pidutsemas nähti. Mõned aastad tagasi õnnestus aga Vene rikkaimal ärimehel ja kunagisel Norilsk Nickel tegevjuhil Mihhail Prohhorovil häbistada Kremlit, olles lennutanud naisi erapeole ja sattudes seejärel kupeldamiskahtlusega politsei huviorbiiti.

South Australia also produces grapes for use in making wine. Mining. Australia is rich in mineral resources. But roads and railways have to be constructed to the mining sites, so that the mining industry depends heavily on foreign capital. During the 1950's, geologists found huge deposits of coal and iron ore in Australia. Manganese, natural gas and petroleum were discovered in the 60's. Australia has got minerals like: copper, gold, silver, zinc, iron, nickel. Manufacturing. Australia imports more manufactured goods than it exports. The nation has to import many of its producer goods factory machinery, construction equipment and so on. Australia's iron and steel industry produces enough of the metals to meet the needs of other industries. The leading manufactured products are food, cars, paper, chemicals, clothing and shoes. Most of the factories are located in and around Sydney ad Melbourne. Forestry and fishing
The Alaskan oil pipeline was built across a caribou migration route. In some places the pipeline has been raised above the ground so the caribou can pass under it. Pesticides have been used to control the hordes of insects. Thousands of migrating birds come to the tundra because of the abundant insects. Through the food chain the pesticides reach many of the animals that live on the tundra. Pollution from mining and drilling for oil has polluted the air, lakes and rivers. The land around some nickel mines in Russia has become so polluted that the plants in the surrounding area have died. Footprints and tire tracks can be visible for many years after they were made. When the sun hits the ruts it causes the permafrost to melt. This causes erosion and the ruts get bigger, and eventually the ruts turn into gullies. Tracks made during World War II have grown so large that some of them are now lakes.
This brought along the great gold rush. Thousands of people went to the new land to find fortune. Forty years later the gold was found in the west. The miners of the east had a very hard time, the water was scarce and the roads were bad. But then the railway was built. Many of people who came to Australia to find gold stayed on to do other kinds of work. The found that Australia has other riches too, such as coal, copper, ironore, nickel, natural gas and more. The forests had good timber. Along seashorepearls and tortoise shells could be gathered. Some needed to manufacture such things as butter, cheese, shoes and clothing. Geographical position Australia is located in southern hemisphere. It's the only continent except for Antarctica that is all south of equator. Sometimes Australia is called the Island Continent. There is a great reason why. It really is an island. It is

Canada is blessed with many natural resources: oil, natural gas, coal, gold, silver, iron ore, zinc, nickel, copper, uranium. Canadians export wheat and other grains meat, dairy products, sugar products and forestry products such as paper and pulp. Canada also has a manufacturing industry producing automobiles and automobile parts and chemicals. The most important customers for export are the United States, Japan, the United Kingdom and Germany Schooling in Canada is free and universal. It's compulsory from the ages of 7 to 14. Schools
CANADA Canada is a vast country, second largest country of the world after Russia. It stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west and to the Arctic Ocean in the North. Canada Covers most of the northern part of North America and its geography is very diverse. Canada's area is about 10 million square kilometers and its population is 31 000 000. Its capital is Ottowa and other main cities are Toronto, Montreal and Vancouver. Almost 75 % of canadians lives within 300 kilometer of the USA border, because the climate is softer in the South. 89 % of Canada is almost unhabited. Its official languages are English and French, but many other languages are spoken too. Like Italian, Chinese, German, Polish, Ukrainian, Dutch and Creek. There are also many native languages such as Algonquian. Most of the canadian's speak English (67 %), but French is very...
These conditions are suitable to the development of mixed wood and broadleaf forests. Mineral Resources Mining and fuel extraction and production accounted for 4.5 percent of Canada's GDP or some US$36.1 billion. Fuel exploration and production dominate this sector, but the processing of other types of mineral resources has grown significantly. In 1996, the top non-fuel minerals were gold with production of US$2.05 billion, copper US$1.47 billion, nickel US$1.45 billion, and zinc US$1.25 billion. There was also significant production of lead and iron. There are about 50 major gold mines in Canada and the country leads the world in technologies which extract gold from rock and soil. The nation is the world's largest producer of zinc and the fifth largest producer of lead. Among the provinces, Ontario is the top producer of non-fuel mineral resources, followed by Quebec, British Columbia, Saskatchewan, and Newfoundland. Each year
Canberra is the seat of the government of Australia. Economy Australia is an outstanding producer of primary products. The country doesn’t import almost any foods. Australia produces food itself. Australia is a major exporter of wheat, meat, dairy products and of course wool. The country produces more than 25 percent of the world’s yearly output of wool. Australia is also very rich in minerals. Coal, bauxite, gold, iron ore, diamonds, natural gas, nickel can be found in Australia. Western Australia has become the most important region of mineral production Mining is an important branch of Australia’s industry too. The famous mining area is Broken Hill in New South Wales. It‘s one of the largest producers of lead, zinc copper and uranium. Australia is also rich in precious and semi precious stones. Black opals, pink diamonds are thought to be very valuable. Tourism is also very important to Australia’s economy
thrives as it is touched by other cultures and other traditions. In 2006, in the Canadian Census, 4.7 million Canadians reported that they were of Scottish origin. Today, there are almost as many Scots Canadians as there are people in the whole of Scotland. 12. Which important minerals are found in Alberta? Canada is abundant in many mineral resources — mined in every province and territory — and a world leader in the production of potash, aluminum, nickel, salt, sulphur and uranium, among others. Today, Canada is the leading producer of potash and is estimated to rank in the top five global producers of aluminum, diamonds, cobalt, nickel, platinum, tungsten, uranium and sulphur Alberta is the country's largest producer of crude oil and gas products (especially natural gas) 13. Which is the main crop grown in the Prairie Provinces? The main crop is wheat, but barley, brassica, canola, and oats are also cultivated. 14

of our international trade is in exporting those resources and buying manufactured goods. Our most important customer for exports is the United States of America. Other export customers are also Japan, the United Kingdom and Germany. Canada exports a lot of products: what and other grains, beef and other meat, oil, dairy products, sugar beets and maple sugar products to name a few. Copper, cold, iron ore, nickel and zinc are the minerals most often sent to other countries. Natural gas and oil are other important exports along with forestry products. Though largely dependent on natural resources Canada has also a strong manufacturing industry. Transportation equipment such as automobiles and automobile parts are our most important manu7factured goods, followed by food, paper products and chemicals. Canada is also a world leader in the telecommunications industry. The Canadarm, a
patchy clouds, letting a sliver of night sky fall onto the caged mirror of the 200-inch (508- centimeter) Hale Telescope. Caltech astronomer Avishay Gal-Yam had two hours before the supernova would dip too low in the sky for the telescope to see it. Still more luminous than a billion suns, the supernova outshone the combined light from all the stars in its home galaxy, glowing white-hot from the radioactive decay of unstable nickel atoms forged in the explosion. Gal-Yam pointed to a computer screen showing a squiggly line--the glow broken down into its component colors, or wavelengths. Each dip in the line represented a wavelength of light absorbed by a different element--silicon, cobalt, calcium, iron--in the debris of the star. Destruction and creation were conjoined on the screen. The elements revealed there, like those from countless earlier supernovas, will eventually find their way into new stars and perhaps new

Canada is one of the world's most important suppliers of agricultural products, with the Canadian Prairies one of the most important suppliers of wheat and other grains. Common agriculture plants are barley, oats, rye and wheat. Canada is the world's largest producer of zinc and uranium and a world leader in many other natural resources such as gold, nickel, aluminium, and lead; many, if not most, towns in the northern part of the country, where agriculture is difficult, exist because of a nearby mine or source of timber. 7. Climate Because of its great latitudinal extent, Canada has a wide variety of climates. Ocean currents play an important role, with both the warm waters of the Gulf Stream in the Atlantic and the Alaska Current in the Pacific affecting climate. Average winter and

Many people left Britain for a new life in Australia. After 1945 people from other European countries, like Italy, Greece, Germany and Holland, began coming to Australia. Since 1945 more than three million people have moved there. Economy Australia is extremely rich in mineral resources like coal, iron, copper, nickel, lead, tin, zinc and others. The forests have much good timber. Along the seashores pearl shell and tortoise shell can be gathered. Australia is one of the biggest producers of diamonds, apals, sapphire, agates. Oil and natural gas have been found in western and southern Australia. Australia has a wide range of industries. Most of them are located in Australia's largest cities which are also ports. Australia

Agriculture is the major industry in Australia. People grow grain and bred sheep. The Australian wool industry is widely recognised as producing the finest quality Merino wool. Eastern Australia is the biggest farming region. Australia is rich in many minerals; mining has been an important branch of Australia's industry. Minerals are found and mined in most states, but Western Australia has become the most important region of mineral production. Gold, manganese ore, uranium and nickel ore are mined there. Australia is also rich in precious and semiprecious stones. Black opals and pink diamonds are though to be especially valuable. Australia is a very rich country because of its mineral sources. People: The earliest humans living in Australia are called Aborigines, and they are descended from among the earliest humans in the world. They are native people who came from Asia about 30 000 or 40 000 years ago

gamma rays. Iron has the highest binding energy per nucleon of any atom. If an atom of lower average binding energy is changed into an atom of higher average binding energy, energy is given off. What is nuclear fusion? Nuclear fusion is the process by which multiple like- charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei. The fusion of two nuclei with lower mass than iron generally releases energy while 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
grows mainly there. Due to warm climate, bananas, peaches, grapefruits, olives, pineapples and sugar-canes are grown in Australia. Economy One of the most important branches in Australia's industry is (and has been) mining, because Australia is very rich in minerals. Minerals can be found in most states, so it is a vital part of Australia's economy. The leading mineral production area is Western Australia, where gold, uranium, nickel ore and manganese ore can be found. Australia is also rich in precious and semiprecious stones, like black opals and pink diamonds for example. It is said that mining produces 20% of Australia's export. Lead and zinc are also found in Australia in quite large amounts from Mount Isa and Broken Hill. Besides those two, copper, uranium, coal and oil are found in Australia. Most of the goods produced in Australia come from New South Wales. Iron, steel, power
Australia Australia is the smallest continent in the world. It is 7.6 million square kilometres big. It is often called the island continent because it is rather small for a continent and very big for an island. There are only five countries bigger than Australia in the World. There are five states in the mainland. Tasmania is also considered as a state so there are six states. The Northern Territory and Canberra are also independent but they are not states. Canberra is the capital of Australia and it is situated between Sydney and Melbourne because both of these cities wanted to be the capital. The population is about 19 million people and growing. New South Wales is the most populated state and Victoria is the most densely populated state. The national language is English. It is English because British settlers came to live in Australia in the past and they brought conv...

composition to some volatile light crude oils. The proportion of light hydrocarbons in the petroleum mixture varies greatly among different oil fields, ranging from as much as 97 percent by weight in the lighter oils to as little as 50 percent in the heavier oils and bitumens. The hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium. The exact molecular composition varies widely from formation to formation but the proportion of chemical elements vary over fairly narrow limits as follows: Composition by weight Element Percent range Carbon 83 to 87% Hydrogen 10 to 14% Nitrogen 0.1 to 2% Oxygen 0.05 to 1.5% Sulfur 0.05 to 6.0% Metals < 0.1% Four different types of hydrocarbon molecules appear in crude oil.

The turbine drives a directly coupled air compressor, which draws air from the atmosphere, compresses it and then cools in the charge air cooler before supplying it to the engine through scavenge ports. Turbocharger consists of a single stage, axial flow exhaust driven turbine mounted on a common shaft with a centrifugal air compressor. The turbine has a nozzle ring followed by a rotating disc with a single row of turbine blades. Blades and nozzles are manufactured of heat resisting steel or nickel alloy. The air compressor consists of a radial flow impeller disc together with an inducer, both of aluminium alloy. Compression will raise the air temperature and a charge air cooler is fitted to reduce the temperature of the air between the turbocharger and the engine inlet manifold. The cooler consists of a tube stack of aluminium brass tubes rolled and solder-bonded into two brass tube plates. Cast iron water boxes attached to the tube
