Air pollution in Japan Birgit Tohter Air pollution The presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk. The effects of air pollution is global warming, heart problems, acid rains etc. There are solutions like public transport, cleaning smokestacks, laws, renewable sources, The history Industrial activity in Japan devoloped rapidly after the World War II. People became really sick and described it as more horrible suffering than death. In the 1970s Japan managed to clean up without sacrificing growth by investing in pollution-control technologies. They made new laws. It was the start of

Air pollution Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for

How can we increase the quality of breathable air? “I’ll go out for a breath of fresh air” is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world? Air pollution is the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life. Firstly, we should use green methods of powering like wind energy and landfill gas energy. This would reduce the amount of harmful gases. Another useful suggestion would be to plant trees. In this way we can increase the source of breathable oxygen. Unfortunately, many companies are contributing to deforestation.

People would have clean water living to stop to drink and to swim in. conditions in throwing There is also a way to fight against our city are litter. Also, air pollution. It is mostly caused by getting worse the city factories, so we should force factories to and worse. should place put filters on their chimneys. We can also Exhaust fumes more ban cars from the city centers and public and smoke garbage transport should be improved, so that we from the bins. People could travel less and less by cars. factories are
How can we reduce air pollution level in cities? The air pollution levels are extremely high in cities, but how can people change this situation? Cars and big factories emit lots of deleterious gases into the air, for example carbonic acid gas, cities are not healthy places to live anymore. Firstly, we should using the public transport. Everybody can walk and bicycle instead of driving cars. Vehicles emit a lot of harmful gases into the air. Every family member does not need his or her own car. One car for the whole family would minimise the number of cars in cities and air pollution levels will come down. Secondly, people have to recycle. It would help reduce factories work. It will emit less harmful gases into the air. Finally, we should plant more trees in cities and also create more national parks. They produce oxygen. In conclusion, there are many ways to make cities better places to live
Unfortunately people don't see that actually cities aren't clean enough. The Aair pollution is growing every day, but how can WE change it? Firstly, we should watch out for the garbage we produce. Many things that are thrown away can be recycled, but some of the people aren't aware of that. They throw things away which may be dangerous for nature. Another solution is to use more buses and bicycles. Every family member doesn't need his/her own car. When you move more in fresh air, you will feel better yourself, your health will be better and you will reduce air pollution levels. Finally, big-factory owners should pay attention where they build on their factories. I think that it is very important that they don't build them in the middle of cities. The pollution twhat comes from the factories is bigdrastic. In conclusion, there are many ways to make our cities' air pollution levels lower. We all need to do what we can. As the old proverb says "To make
How can we reduce air pollution levels in our cities? Is our cities a safe place for us? Tons of harmful gases emit to the air everyday. Factories have caused this problem. We need to do something fast before our city doesn`t become deserted. Firstly, we have to create industrial park. It will help to reduce factories in the cities, where a lot of people live. Another solution is to start stricting the laws. If the laws be very strict, then less and less persons will be able to get a license for the new factory. Finally, we should renovate our factories. Modern plant emit less unhealthy gases. This would
How can we reduce air pollution levels in our cities? Is the air in our cities clean? Unfortunately does not seem like it. Air is getting more polluted every day and we are constantly breathing that air. We need to do something fast before it is too late. Firstly, there is too much traffic in the city centre and cars emit bad fumes. A good idea would be to introduce parking and riding schemes. In this way there will be fewer cars in the city centre and in longer perspective air will get a lot cleaner. Another problem are factories polluting the air. There are so many factories that there is always smoke covering the city. It would help if we could create industrial parks. In this way less smoke will cover the city. Also a big issue is rubbish being burned. It would be a good idea to introduce a recycling scheme. In result less rubbish will get burned. In conclusion, there are many ways to make our cities cleaner. We all need to do whatever we

Rosseau, jäid püsivalt metsa elama. Vahetu side loodusega ja talurahva eluoluga suunas neid looma uutmoodi kunsti, mida hakati nimetama realismiks. Mida nimetatakse Barbizoni koolkonnaks? Barbizoni koolkonda kuulusid kunstnikud, kes püüdsid reaalsust ilma seda moonutamata või ilustamata edasi anda. Koolkonna moodustasid maastikumaalijad, kes käisid suvel maalimas Fontainebleau metsas ja elasid Barbizoni külas. Mida tähendab termin plein air (pr. k.)? See on prantsuse keelest tulnud termin, mis tähendab `'vabas õhus''. Seda kasutatakse seletamaks väljas maalimist. Kunstnikud on pikka aega väljas looduses maalinud, kuid 19 sajandil sai naturaalses valguses töötamine Barbizoni koolkonna jaoks väga tähtsaks. Milline kunstnik võttis kasutusele termini ,,realism"? Mis asjaoludel ta seda tegi? Gustave Courbet, tema juhtiski seda kunstilist liikumist. Missuguseid uusi teemasid kunsti tõid realistid?

Most types of truck air brakes are drum units, though there is an increasing trend towards the use of disc brakes in this application. The compressed air brakes system works by drawing filtered air from the atmosphere, compressing it, and holding it in high-pressure reservoirs at around 120 PSI. When needed for
Since the invention of the internal combustion engine, automotive engineers, speed junkies and racecar designers have been searching for ways to boost its power. One way to add power is to build a bigger engine. But bigger engines, which weigh more and cost more to build and maintain, are not always better. Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. A turbo/supercharged engine produces more power overall than the same engine without the charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines
The environment in realtion to mobility/transport in Europe Air pollution is problem all over the world. Through some pollution comes from these natural sources, most pollution is the result of human activity. The biggest causes are the operation of fossil fuel- burning power plants and automobiles that combust fuel. Combined, these two sources are responsible for about 90% of all air pollution in the United States. All kind of pollutions can lead us to serious health problems. For example, air pollution is increasingly being cited as the main cause of lung conditions such as asthma - twice as many people suffer from asthma today compared to 20 years ago. Every year, 3.2m Europeans are diagnosed with cancer - the most common cause of death after heart disease. Most widespread are cancers of the lungs, breast and colon. Diseases such as bronchitis, lung
WHAT IS A RESPIRATOR? A respirator is a type of personal protective equipment (PPE). It is worn over the nose and mouth. Some respirators also cover the face and eyes. A respirator can protect you against breathing in harmful contaminants that are in the air - if you use it properly. MIS ON RESPIRATOR? Respiraator on teatud tüüpi isikukaitsevahendeid (IKV). On kulunud üle nina ja suu. Mõned respiraatorid ka katta nägu ja silmad.Respiraator võib teid kaitsta vastu hingamise kahjulikke saasteaineid, mis on õhus - kui te kasutate seda õigesti. WHY IS IT IMPORTANT TO WEAR A RESPIRATOR? Workers doing cleanup or ripout jobs create a lot of dust that gets into the air. This dust is there even if you cannot see it

I am going to talk about Neon's history extraction physical properties chemical properties uses health effect Neon is the chemical element that has the symbol Ne and atomic number 10. Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.
Technology. I'd like to talk about environment, its pollution and protecting. I shall only take 3 minutes of your time. Let me begin with the word enviroment and what it means! It means surroundings in which people, animals and plants exist. These are the things that we need, to be alive, but they are also many man-made things and technical progresses that harm the nature. Therefore we can´t live on this planet without basic components which are needed for human existence - air, water and soil. Firstly air, which is mostly a mixture of oxygen and nitrogen. People, animals and plants can ´t live without air. Without oxygen there would be no fire. So we can see, that air is the basic condition for life on the Earth. Did you know that till 18th century people didn´t know composition of the air? They only used the knowledge of moving the air. Turning to water which covers over 71 % of Earth´s surface. It is also in underground and, naturally, in the air
from which the future British colony the Gold Coast would take its name), the focus shifted to the lucrative slave trade in the 17th century. The area later became known for growing cacao, the source of cocoa beans. Introduced there in the late 19th century, cacao continues to provide an important export for Ghana. Ghana's climate, like that of the rest of the Guinea Coast, is determined largely by the interplay of two air masses: a hot, dry continental air mass that forms over the Sahara and a warm, humid maritime tropical air mass that forms over the South Atlantic. Both air masses move toward the Equator with their hemispheric winds and meet at the Guinea Coast for several months each year. Continental air moves southward with the northeast trade winds, known in western Africa as the harmattan, and maritime tropical air moves northward with the southwest trades.

Post-alveolar sounds are produced by the tongue touching the area before the alveolar ridge. Dental sounds are produced by the tongue touching the front teeth. Bilabial sounds are produced by the contact of both lips. Labiodental sounds are produced by lip-to-teeth contact. Distribution is the act of looking sounds in different contexts and positions they can occur in. Any speech sounds must always have air flow and some kind of blockage or modification to the air flow. There are 2 kinds of sounds in English: Vowels that are produced do that the airstream is not obstructed – they can stand alone meaning that they can be produced without consonants before or after them Consonants that are produced with some restriction or closure in the vocal tract that the air flow is obstructed – consonants require some vowels around them

The most pressing environmental issues in Estonia The earth is considered as one of the most beautiful planets in the Universe. Unfortunately, our planet is suffering due to many problems which should be solved before it is too late. Of course our country is not an exception. The major problems that are facing our country today are air and water pollution and recycle problem. Also we have, for example, deforestation problem and traffic jams, for instance, in Tallinn in rush-hour. Nevertheless, those problems are not so significant than previous. One of the biggest problems in Estonia is air and water pollution. One example of air pollution is exhaust fumes. Today we have a lot of transport: cars and buses, in the main in our capital. Gases which are produced by cars contain carbon dioxide

Good afternoon, i talk about environmental problems in Estonia. plakatile ei kirjuta :D Main environmental problems in estonia: · Oil shale mining and burning · Excessive tree felling · Air pollution · Eutrophication Oil shale mining and burning. Estonia environmental problems are mostly caused by oil shale mining and burning. About 30 000 Hectare ground is unusable. We have a large ash mountains thanks to burning of oil shale. To reduce pollution we need to decrease mining of oil shale and shale-based electricity producing. Air pollution the biggest air pollution is in large cities. It´s caused by big factories, a lot cars and deficient environment ordinance.
Environmental issues in Estonia The Earth is considered to be the most beatiful planets in the Universe. But our planet is threaten by environmental problems. Even a small country like Estonia can make difference. Our capital city is fighting against air pollution. But people produce much refuse and ways of recycling are getting old. Water pollution is also a problem in Estonia. We have factories that let their waste run into rivers. One of the biggest problems in Estonia is air pollution. Our air is polluted by exhaust fumes, because today we have a lot of cars, buses and other machines. In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the greenhouse effect. Tallinn wants to fight against it by offering public transportation for free, to Tallinn citizen
Some of us struggle with it even after graduating. Lucky are those who have had a specific goal in mind for long enough where they can keep an eye on the target and know what they need to do and work on it right away. Aviation has always been one of my biggest intrests since the eighth grade. I became interested in it after my brother had applied to the Estonian Aviation Academy. Unfortunately he did not make it and, of course, my desire to become an air traffic controller began to increase due to my brother's failure. I have never really had a real experience in aviation. Luckily, I had a chance to be a work shadow to a professional air traffic controller to see how it all works. This experience seemed long, however it was interesting and really opened my eyes. At first I thought that controlling air traffic can not be that hard, that it is just like another computer game!

CYLINDER FRAME The cylinder section of the engine consists of a number of cylinder blocks, which are tightened together with the engine frame and the bedplate by means of through- going stay bolts. Two central bores, one at the top and one halfway down inside the cylinder block, enclose the cylinder liner. The upper part of the cylinder block forms part of the cooling water space around the central part of the cylinder liner, whereas the lower part forms the scavenge air space. A central bore in the bottom of the cylinder block encloses the piston rod stuffing box. The bottom is double with a hollow space through which cooling water is circulated. On the exhaust side of the cylinder block there is a circular opening leading into the longitudinal scavenge air receiver of the engine. Furthermore, there is an inlet pipe for cooling and lubricating oil. The cylinder block is provided with cleaning and inspection covers for the cooling water and scavenge air spaces.
improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. 1.1.3) A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between. The basic operation of the gas turbine is similar to that of the steam power plant except that air is used instead of water. Fresh atmospheric air flows through a compressor that brings it to higher pressure. Energy is then added by spraying fuel into the air and igniting it so the combustion generates a high-temperature flow. 1.1.4) A diesel-electric transmission system includes a diesel engine connected to an electrical generator, creating electricity that powers electric traction motors.

Volcanic eruption (summaries) 1. Volcanic eruption happens when various gases and lava are discharged from a volcanic vent. The most dangerous type of volcanic eruption is when freshly erupted magma is flowing. During the explosion, magma with rock fragments, flies into the air and then falls down. Magma, which have temperatures over 1200 degrees, may flow further than 40 km from the original disaster site. The lava destroys many building and plants also volcanic ash will harm humans when they breath it in. 2. The volcanic eruption of Mount Kelud on Java island blasted ash and debris 18 kilometers into the air. Eruption killed three people and forced 100,000 people to evacuate the area. Mount Kelud, what is 1,731 meter high, had been rumbling for

Complementary distribution phonetic units that never occur in the same environment are said to be in complementary distribution. For example, clear/l/ and dark/l/. NB! The sounds we produce and hear are continuous: we move our organs of speech continuously and produce a continuous signal still it is possible to divide speech into units, which is called segmentation. The sounds of languages can be produced by: pushing air out of the lungs through the vocal tract (pulmonic, egressive) sucking the air into the mouth (ingressive) NB! Without air we cannot produce sound. There are two classes of sounds: consonants vowels Consonants are produced with some restriction or closure in the vocal tract that impedes the flow of air from the lungs. Vowels are produced so that the airstream is relatively unobstructed. NB! Any speech sound will always exhibit two components in some form or other:
Vehicles used in different modes of transport Contents ● 1.What is transport? ● 2.Airways ● 3.Roadways ● 4.Waterways ● 5.Railways ● 6.Pipelines ● 7.Conclusion 1.What is transport? Means by which a shipment is moved from point “A” to point “B”, such as by air, rail, road or sea. 2.Airways Air freighting is commonly used by businesses for the delivery of goods from distant suppliers. This type of transport is useful to deliver products within short time limits, fragile goods and products that are not bulky. Products in high demand and in short supply may also be air freighted in order to meet customer demands. The value ratio will be a determing factor. 3.Road Road a very popular mоde of transport used by
I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also
