Despite its size, Burj Al Arab holds only 28 double-story floors which accommodate 202 bedroom suites. One night in hotel cost about 13 500 euros. References http://www.jumeirah
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 getting it is too expensive. We can only depend on nuclear power for a few years or decades. On the other hand, we will always have wind and solar power. Right now, producing solar energy is quite expensive but as technology improves, we will hopefully be able to produce solar energy with lower costs. The world should use as much wind and solar power as possible. As years go by, we will hopefully find a way to produce cheap and environmentally-

To: Ms Maire Liidlein From: Kerli Neljas Date: 16th December Subject: Recommendation report about Haapsalu Introduction Haapsalu is a small, friendly and romantic town is a real summer paradise and in summer a lot of holidaymakers visit this. They come for the warm seawater, curative mud, peacefulness. A lot of people visit the resort every summer, there are many different ways to spent time there, both for tourists and locals. Old Town of Haapsalu and museums People who are interested in culture and history can visit the Old Town and museums. For example the Estonian Railway Museum, the Episcopal Castle Museum, the Läänemaa Museum and others. I think that the city itself is one of the greatest historical places

The most powerful was the Cannon Tower on the Northern Bastion from about 1470, restored in 1971-72. In 1559 Bishop Johannes V Münchhausen sold his property in Saaremaa (Oesel) and Kurland to the Danes. The Danes modernized the defence systems of the castle. The work began in about 1600 and lasted till 1640. Using the old belt of walls, they erected a mighty system of earthwork with bastions and encircled it with a 30 m wide moat, filled with seawater. On the ground of Brömsebro peace treaty in 1645 Sweden took possession of Saaremaa. On September 15, 1710 the Swedish garrison, ravished by the plague, surrendered to the Russian army with no resistance. After Russia founded Bomarsund castle on just-occupied land islands and in the vicinity of the Swedish capital, Kuressaare was once and for all excluded from the list of the fortifications of the Tsarist Russia in 1836. A year before the castle had been sold to the
by Guy Stewart Callendar. Solar activity Since 1978, output from the Sun has been precisely measured by satellites. These measurements indicate that the Sun's output has not increased since 1978, so the warming during the past 30 years cannot be attributed to an increase in solar energy reaching the Earth . The graphs show otherwise. Effects of global warming on oceans Global warming can affect sea levels, coastlines, ocean acidification, ocean currents, seawater, sea surface temperatures, tides, the sea floor, weather, and trigger several changes in ocean bio-geochemistry; all of these affect the functioning of a society. Impacts on society The rise in sea level along coastal regions carries implications for a wide range of habitats and inhabitants. Firstly, rising sea levels will have a serious impact on beaches— a place which humans love to visit recreationally and a prime location for real estate
helicopters for the short flight to the airport. Highlights The 27th-floor Skyview Bar is the best place to appreciate the heights of the world's tallest hotel while you can check out the hotel's supermodern design. One of its restaurants, Al Muntaha is located 200 metres above the Persian Gulf, offering a view of Dubai. The main chef there (Edah Semaj Leachim) was awarded Chef of the Year 2006 and also owns the restaurant. Another restaurant, the Al Mahara features a large seawater aquarium, holding roughly over one million litres of water. The restaurant was also voted among the top ten best restaurants of the world (by Condé Nast Traveler). There's a fully equipped spa, a club for kids and a private beach on site, along with every imaginable water sport a short stroll away at the Burj's sister, the Jumeirah Beach Hotel. Trick to get in for free: There is an entry fee to the hotel if you just want to see it from the inside, which is about 50 euros
public disquiet and interference with recreational activities such as bathing, boating, angling and diving. Hotel and restaurant owners, and others who gain their livelihood from the tourist trade can also be affected. The disturbance to coastal areas and to recreational pursuits from a single spill is comparatively short-lived and any effect on tourism is largely a question of restoring public confidence once clean-up is completed. Industries that rely on a clean supply of seawater for their normal operations can be adversely affected by oil spills. If substantial quantities of floating or sub-surface oil are drawn through intakes, contamination of the condenser tubes may result, requiring a reduction in output or total shutdown whilst cleaning is carried out. Biological effects of oil Simply, the effects of oil on marine life, are caused by either the physical nature of the

The principle behind is, that an incoming wave flows over a tapered channel of concrete into a a higher basin. The tapering is used to enlarge the velocity of the water flow following the continuity equation. The kinetic energy of the wave is transferred into potential energy of stored water in the upper basin. This principle follows the hydrodynamic law of Bernoulli's equation. A Tapchan wave power plant uses a continuous flow of the seawater stored in the upper basin through a low pressure turbine driving a generator of conventional construction to generate electricity. Low head Kaplan turbines are used mostly to convert potential energy into electrical energy. The water storage (reservoir, basin) helps smoothing the electric output. With its integral storage system, a Tapchan is different to most of the other regenerative energy conversion technologies. The following equation governs the energy of water waves:
due to photolysis in the lower atmosphere is 1.6 hours at a solar zenith angle of 40 degrees. Based on its rate of reaction with photochemically produced hydroxyl radicals, formaldehyde has a predicted half-life of approximately 19 hours in clean air and about half that time in polluted air. Water When released to water, formaldehyde will biodegrade to low levels in a few days. In nutrient- enriched seawater, there is a long lag period (40 hours) prior to measurable loss of formaldehyde by presumably biological processes. Formaldehyde in aqueous effluent is degraded by activated sludge and sewage in 4872 hours. In a die-away test, using water from a stagnant lake, degradation was complete in 30 hours under aerobic conditions and 48 hours under anaerobic conditions. Bhattacharya and Parkin used anaerobic chemostats to study fate and kinetic effects of sludge and
Several commercial prototypes have been build, and more are in development. * Wave power uses the energy in waves. Wave power machines usually take the form of floating or neutrally buoyant structures which move relative to one another or to a fixed point. Wave power has now reached commercialization. * Osmotic power or salinity gradient power, is the energy retrieved from the difference in the salt concentration between seawater and river water. Reverse electrodialysis (PRO) is in the research and testing phase. * Vortex power is generated by placing obstacles in rivers in order to cause the formation of vortices which can then be tapped for energy. * Deep lake water cooling, although not technically an energy generation method, can save a lot of energy in summer. It uses submerged pipes as a heat sink for climate control systems. Lake-bottom water is a year-round local constant of about 4 °C

Used oil drains to the bottom of the crankcase and passes through strainers by gravity to the drain tank. A pump (5) sucks oil from a lubricating oil drain tank (3), which in large engines is most often a bottom tank below the main engine. It is fitted with an air vent, level measuring gauge and sounding pipe. To reduce the possibility of contamination of the lubricating oil in the bottom tank as a result of leaks, all the remaining bottom tanks containing, for example, fresh water, seawater or fuel oil, can be separated from the lubricating oil bottom tank by coffer-dams (2). To safeguard the pump, a course filter (4) is inserted between the pump and the bottom tank. The pump forces the oil a through lubricating oil cooler (6) and filters (7) to the main engine (1) where the oil is distributed to bearings and pistons.
