Teenagers criminals
2009-12-22
Last year teenagers committed about 535 crimes. During one-year period delinquency raised 16.6%. Biggest part of crimes was committed by teenagers aged from 13 to 19. Thefts from cars are 42.3% and burgalyries-31.5% off all committed crimes. Every 6th crime is burglary. Films of violence, detailed crime stories in the press have a big influence for crimes increasing. In 1998 investigated 47 teenagers’ burglaries in Siauliai, this year, after 4 months - 28. 22 of them were investigated. Comparing with last year Siauliai has 46.7% increases. Dogging adult’s steps teenagers begin extort wealth, cheat, make drugs, use guns, process money, resell burglaries things. Statistic shows that drunk or intoxicated teenagers made many crimes. From 615 criminals 249 are pupil from secondary school. 53% guilty juveniles don’t study or work. We can group teenager criminals into two groups. One group of them become criminals, because those teenagers are weakling persons, their friends make great influence on them on their way of thinking or by these friends help they do a crime for fun. Other group of teenager’s criminals does crimes for their bad social status. How a teenager can become a criminal? Teenager can become a criminal when: • This teenager’s friends make great influence on him on his way of thinking. • This teenager is a weakling person and he can’t resist the temptation to alcohol, drugs, so he does a crime, because at that moment he did not understand what he was doing, because he was drunk. • This teenager does not have what to do in his spare time, so he does a crime just for having fun. • This teenager’s social status is bad, so he does a crime for having money. What kind of teenager criminals are in Lithuania? A teenager criminal can be: • vandal (a person who likes to draw on the cars, walls, houses, who likes to brake something); • filches (some kind of stealer); • pilferer (some kind of stealer); • pugnacious person (a person who likes to fight against somebody); • burglar (a person who steals from the houses); • rapist (a person who likes to rape women); • racketeer (a person who orders another person to give all his money); As we all know the bigger part of teenager criminals are of male sex. And we also know that a teenager criminal is not so dangerous like a professional criminal, who has got lots of experience in that sphere. And that a teenager criminal’s way of life could be easily changed to another way of life, normal way of life, just you have to show that there is another way of living. Police account Why do youngsters become criminals? It’s the question, which bothers a lot of people. Here are some reasons why that happen: Youngsters don’t have interesting facilities and hobbies These are the main things why youngsters become criminals. Now we want to tell some ideas how to solve this problem. Should be some educational centers where young people could find a professional psychologist that would help a lot. Schools should try to help solve that problem and organize some lectures for students about crimes, drugs, how drugs can make people do very bad things. We were explaining how to solve that problem, but we forgot to tell what kinds of crimes are most popular. There are a lot of hooligans, but it isn’t the biggest problem in our country. They have a lot of problems with muggers, because they are getting money like that for drugs and then they start feeling bad and start robbing (old ladies), stealing or even burgling. That makes a lot of problems for police officers. And the other kind of crimes is shoplifting (that is the most popular kind of crimes) Very many shops loose a lot of money, because of that. And the main thing with shoplifters is that they get used to it and become addict. We think you want to ask why police isn’t doing anything about that. But they do. They try to organize some summer caps for youngsters try to take them to psychologist or to talk with them; some times they organize shows for pupil. So I think you can’t say that police is doing nothing.
Technology progress
2009-12-22
Now we are talking about such things like Internet, computerized information systems, information databases. These things are closely connected to our life and we couldn’t imagine living without them. Not only couldn’t a person live without these new technologies. Now everything – banks, airports, governmental system, telephony, etc. are based on latest technologies. Why is it all so necessary? It is only because a man needs to know more and reach more than he has and knows now. Scientists search for other life in space and they use latest technology – everything is computerized. Now we can see the progress of congnitivistics – computer intellect. Maybe after 10 or more years we will have thinking computerized systems, which will ease our life even more. This information revolution affects all the people. 10 years ago there were only 4-5% working people, who worked with information. Now this percent exceeds to 70% and it’s growing fast. And so we are talking about information society. For Lithuanian people it is very hard to overcome our old beliefs, when we lived in Soviet Union. Of course it will take some time, but it will be only useful. Information becomes a strategically important element in everyday life and in every organization that wants to be successful. We must go together with technology because this is the only way to achieve more. Technology is developing and every tomorrow can be very surprising for us. Technology progress never stops. But we must also remember that technology can be also dangerous and bring as much harm as good. It is good that we have lasers and other related technology when they are used to cure people and for good purposes. But when this technology turns back to us with very unfriendly intentions then it can be too late. So we must be aware of this and maybe this is the only disadvantage of technology progress.
Stomatitis
2009-12-22
An inflammation of the mouth, often a symptom of systemic disease. Fetif breath odor and blood-tinged saliva is a symptom of lesioned oral mucosa. Etilogy. Stomatitis may be caused by infection, trauma, dryness, irritants and toxic agents. Infectious agents: streptococci, gonococci viruses of herpes, also avitaminosis, lack of vit B and C. Mechanical: cheek bitting, jagged teeth, orthodontic appliances, excessive use of alcohol, tobacco, hot foods, or spices. Also – mercury, bismuth, acid fumes and metal dust. Symptoms and signs. Allergic stomatitis – is characterized by an intense, shiny erythema, dryness. Candidiasis – the infection usualy begins on the tongue and buccal mucosa and may spread to the palate, gums. Dzagnosis. Physical examination is obligatory. Direct smears and cultures from the lesions may discloss a pathogen. Treatment. Meticulous oral hygiene is always necessary. Candidiasis responds to nystatin.

When you get a phone call and other party says ‘’hello’’, often you recognize the voice. Visual impressions, tastes, and smells are also coded in LM. If encoding is proper, in the case we need that information most probably we will be able to use it. 2. Storage. Some information is almost certainly lost from storage, particularly when there is a disruption of the processes that consolidate new memories. The biological locus of consolidation includes the hippocampus and amygdala, brain structures located below the cerebral cortex. Direct evidence of storage loss comes from people who receive electroconvulsive therapy to alleviate severe depresion. In such cases, the patient loses some memory for events that occurred in the months prior to shock, but not for earlier events. These memory losses are unlikely to be due to retrieval failures, because if the shock disrupted retrieval then all memories should be affected,not just the recent ones. 3. Retrieval. Many cases of forgetting from LM result from a loss of access to the information rather than from a loss of the information itself. That is, poor memory often reflects a retrieval failure rather than a storage failure. Trying to retrieve an item from LM is like trying to find a book in a large library. Failure to find the book doesn’t necessarily mean it is not there; you may be looking in the wrong place, or it may simply be misfiled and therefore inaccessible. There are a lot of evidence for retrieval failures. For example, you cannot recall a specific name or date during the exam, and you remember it just after the exam. Another example is ‘’tip-of-the-tongue’’experience in which a particular word lies tantalizingly outside our ability to recall it. We may feel quite tormented until a search of memory finally retrieves the correct word. The better the retrieval cues, the better our memory. Retrieval failures are less likely to happen when the items are organized during encoding and when the context at retrieval is similar to that at encoding. Retrieval processes can also be disrupted by emotional factors. Among the factors that can impair retrieval, the most important is interference. The essence of it: if we associate different items with the same cue, when we retrieve one of the items, the other items may become active and intefere with our recovery of the target. For example, if your friend Dan moves and you finally learn his new phone number, you will find it difficult to retrieve the old number. They interfere.

Smoking (2)
2009-12-22
Smoking is very harmful not only for smokers but also for those who are near the smokers. This addiction causes heart ant pulmonary diseases, cancer and a lot of other horrifying diseases. The worse thing is that smoking causes psychological dependence. Therefore should smoking be banned or allowed in public places? There are two different opinions in our society, to ban smoking in public places or not. Firstly people are convinced that smoking in public places is appreciable as a society health problem. They think that smoking should be banned, because smoke harms all of us. On the other hand we ought to respect smoker’s interests and alternatives. Everyone is responsible for their self health. However these people who smoke are dependent on smoking, so in future they can try to use other drugs. The more people become addicts the worse our society will be. Though, to stop smoking requires a lot of amenities so for some smokers this can be too hard to do it. Adding up smokers can unwind and relax just when they are smoking. Such is their lifestyle. 180 So this question has two different sides. Although smoking is very harmful not only for smokers but for all of us who are near smokers, smokers alternative should be respected.

Smoking
2009-12-22
It has been estimated that something like 17 million Americans try to "quitt smoking" each year and only about 8% succeed! Statistical analysis has shown that the success rate is much higher if the doctor was involved in counseling and helping a person to quit. I'm not sure if any studies have been done to see if a pharmacist's encouragement to quit produces similar results, but I am going to urge you to prepare yourself to "kick" the habit. Let me remind you why it is so important. Smoking can either directly cause or be a major risk factor in bringing about the following: Cancers of the lung, liver, pancreas, bladder, brain, breast, and cervix. Chronic obstructive lung disease, asthma, pneumonia, and tuberculosis. Hypertension, coronary artery disease, aortic aneurysm, and stroke. Retardation of fetal growth, congenital malformations, premature births, spontaneous abortions, and sudden infant death syndrome. Peptic ulcers, osteoporosis, and premature aging. Even breathing the air in a smoke filled room is associated with higher risks of some of these conditions! If you quit, do the risks return to the same level as nonsmokers? Yes, in many cases they do. Nicotine is only one of the toxins in cigarette smoke. Other toxic chemicals include carbon monoxide, ammonia, and nitrosamines. Smoking is considered a true addiction by the US Surgeon General. So, it is not easy to quit and although relapse is common, it should be viewed as part of the process. Most people are successful only after several attempts. The use of patches which release nicotine into the body are often very helpful. But, programs which include counseling and behavior modification have the highest rates of lasting abstinence. You can be of service to your friends and family by helping them to confront the issue of what smoking does to their health and to those around them. Encourage them to seek professional counsel on a smoking cessation program that fits their needs. Then stick with them as encouragement from friends and family can greatly enhance their chances for success. Remember, this pharmacist is ready and willing to help. Kicking the habit promotes "Good Health."... lighten up... it will be good for your “good health.”

First of all, the slogan misses an important point. The death penalty does not punish people for killing, but for murder. Killing is justified when it is done in self-defense. Killing means to cause death. Murder, on the other hand, is defined as, "the unlawful and malicious or premeditated killing of one human being by another". "Kill," "murder," and "execute" are not interchangeable terms. Death penalty opponents would like us to believe otherwise. Just because two actions result in the same end does not make them morally equivalent. If it were so, legal incarceration would be equated with kidnapping, lovemaking with rape, self-defense with assault, etc. Therefore, the slogan is better stated, "We execute people to show people that murder is wrong." Morality is defined as "the principles of right and wrong." As moral creatures, humans deserve praise for good deeds, and punishment for bad ones. Punishment may range from a slap on the wrist to death, but the punishment must fit the crime. Morally, it is wrong to incarcerate someone for murder. A sentence of life in an air-conditioned, cable-equipped prison where a person gets free meals three times a day, personal recreation time, and regular visits with friends and family is a slap in the face of morality. People will say here that not all prisons are like the one cited. This betrays an ignorance, however, of current trends. Eventually, criminal rights activists will see to it that all prisons are nice places to go. But regardless of the conditions of a particular prison, someone who murders another human being can only be made to pay for his actions by forfeiting his own life. This is so, simply because a loss of freedom does not and cannot compare to a loss of life. In reality, the murderer actually gets off easy when he is sentenced to death. Executions in this country are performed by lethal injection and electrocution. If a person is lethally injected, he is first put to sleep, and then he is administered drugs that will stop his heart. If a person faces the electric chair, he is dead within seconds. Compare this to the heinous crimes of the murderer, where often the victim will go through excruciating pain for minutes, hours, or sometimes days. The opponents of death penalty gives five reasons why the death penalty should be abolished. Those reasons are quite commonly given, so I will address their objections here. 1. The death penalty is racist. 2. The death penalty punishes the poor. These are basically the same argument. What it boils down to is "the death penalty is not applied fairly." This cannot be an argument against the death penalty. If it were, then it would be an argument against all punishments. To argue that the death penalty is to be abolished because it is not fairly imposed is to admit that if it were imposed fairly it would be okay. This is not an argument against the death penalty but an argument to improve the justice system. Is the system unfair? Fix it. What is unfair is not that the black and poor prisoners get what they deserve. What is unfair is that the rich and white prisoners do not. 3. The death penalty condemns the innocent to die. There is absolutely no proof for this statement. The possibility of an innocent person being executed is extremely small, and continues to decrease with the improvement of forensic science. It is true that death row prisoners have been released, but it is not true that they were innocent. Consider the following fact: A judgment of acquittal is final. Even if overwhelming evidence is later uncovered, the prosecution can never appeal. Likewise, if a conviction is reversed on appeal because the evidence of guilt was legally insufficient to prove guilt beyond a reasonable doubt, then the defendant cannot be retried. Furthermore, if a court decides that the evidence brought against the defendant was legally insufficient, it is not saying that the defendant was actually innocent. By making this decision, the court is merely saying that the prosecution did not prove the defendant's guilt beyond a reasonable doubt. We must make a distinction when we use the words "acquittal" and "innocent." The media often overlooks this distinction, and thrives on causing widespread panic that an innocent person was falsely convicted. Being acquitted, however, does not mean that the defendant did not actually commit the crime. A jury must acquit "someone who is probably guilty but whose guilt is not established beyond a reasonable doubt. 4. The death penalty is not a deterrent against violent crime. The death penalty as a deterrent to crime is not the issue. Capital punishment is, pardon the redundancy, a punishment for crime. As a punishment, it is 100% effective; every time it is used, the prisoner dies. Additionally, the death penalty is actually 100% effective as a deterrent to crime: the murderer will never commit another crime once he has been executed. 5. The death penalty is cruel and unusual punishment. The death penalty is not cruel and unusual punishment. The framers of the Constitution supported the death penalty, so it is ridiculous to claim that cruel and unusual punishment refers to the death penalty. Furthermore, it is logically impossible to be cruel while punishing a guilty murderer for murdering an innocent victim. I have tried to argue here that the death penalty is moral and just. We must never forget that no one has to be executed; if no one murders, no one is executed. Murderers are not innocent people fighting for their lives; that statement describes their victims.
Short-term memory
2009-12-22
SM is a intermediary (tarpininkas) storage between SeM and LM. One of its functions is in some way to process information and transmit it for further processing and storage. For this first of all is used encoding. Acoustic encoding is very common in SM and for a long time psychologists thought that was the only method of encoding. Evidence of its importance is documented by that show, for example, the letters T and C are more likely to be confused in SM than C and O, even when they are presented visually.Such results suggest that subjects are recoding the visual symbols to acoustic representations, thus explaining why the similar-sounding C and T are more easily confuced than the different-sounding C and O. There is ample evidence of visual and especially semantic encoding in SM as well. One of the most important aspects of SM is its limited capacity. It is 7 ± 2 elements for a wide variety of materials. There is a tremenduous amount of variation of what can be put into each of those seven bits. For example, we can hold seven numbers in our SM, but also7 words, 7 pictures, or sometimes even 7 sentences. In fact, the bits may be made considerably larger through the processes of chunking, by which we combine pieces of information together to allow them to take up less space in working memory. Another important process that occurs in SM is rehearsal, the temporary activation or recycling or information through memory. Rehearsal may be maintenance (holds information in SM long enough for it to be acted upon in some way) or elaborative (nuodugnus) rehearsal (helps transfer information to LM). Elaborative rehearsal relates information to other concepts already in LM and and develops new asociations between these concepts. The explanations offered for forgetting from SM generally cluster around two general phenomena. On the one hand forgetting is said to occur due to decay of the memory trace over time. The other class of explanations uses the consept of interference. Material is forgotten because other material that is similar is some way interferes by replacing or distorting it. Interference may be retroactive, which means it occurs after original leaning. And proactive, when interfering material comes first and hinder the learning of something else later. We use SM when we are thinking about something at the moment, solving problems (in this case information is retrieved from LM to SM). SM plays a role in understanding language. Findings suggest that we have a special memory system for processing language. A patient who has a defective memory span but normal language understanding has an impaired SM but an intact language memory. The special memory for language seems limited to relatively simple sentences. Once sentences become complex SM is brought in for help. When it come sto higher-level language processes like following a conversation or reading a text, SM appears to play a crucial role. When reading for understanding, often we must consciously relate new sentences to some prior material in the text.
Our telephone company made a survey about mobile phones in Lithuania. There are a lot of different mobile telephone‘s models. Actually it is very difficult to find a family without mobile phones. Here are some opinions: URTE. There are 3 mobile phones called 'Nokia' in her family. Why 'Nokia' ? in her opinion 'Nokia' is the highest quality mobile phone in Lithuania. She used her mobile phone to get in touch with her friends and parents. During the week she spent 7 hours on her mobile phone. LISA. There are 4 mobile phones in Lisa‘s family. Mobile phone is her best friend. During the week she spends 30 hours. She calls her friends, parents, who live in England. TOM. Tomas got a mobile phone as a birthday present, but he uses it not very often. He adores to talk to somebody lively. LUKAS. Lukas used his mobile phone at work. He is a manager. He also calls his friends. He spends 40 hours during a week on his mobile phone. Conclusion: Mobile phones are getting more and more popular in Lithuania. There are a lot of styles, colours mobile phones. Mobile phones have a lot of advantages: • It‘s very comfortable to use them; • You can get information, you need, very quickly; • You can get in touch with people all over the world; • Mobile phones are very fashionable; • New technologies...

Popular music
2009-12-22
. I’m not saying all pop fans are closed minded to the point where they listen to the music genre that is currently trendy in hopes of it helping them position themselves socially. I’m also not denying the fact, people like that are out there. In most cases, I think people listen to pop because for some reason they’re not involved in another music scene, so it’s all they know exists. Record labels systematically chose who they want to sign, and then promote them to the public. Therefore, they have an enormous influence on what music America and many other countries listen to. This is bad news because corporate promoters don’t just go out looking for talent to sign to their label regardless of what kind of music it is attached to. Companies use statistics to determine what they think will sell, and sign whoever fits the right criteria. They don’t bother looking for artists who aren’t playing what’s hot; they want bands playing the sound they know sells. Labels also want bands with catchy songs, and I don’t know about you but I think catchy giggles are for advertisements. Real musicians have to be careful where they put their signature, because any one who takes them self seriously wouldn’t stand for a company who censers their art. Also you may have noticed TV is now just as much a source of music as radio, so you better be an attractive conformist if you want to be promoted as an artist in the business of pop music. MTV, without doubt, plays a major role in how generic popular music has become. Obviously the birth of music videos gave big business a chance to sell music to the other four senses. The real opportunity for MTV to cash in on the music industry wasn’t just picking up their crumbs. Just luring in those people whose ears are uninterested in music with flashy colors and shiny things is no longer their motive. Quickly MTV figured out eye candy doesn’t sell nearly as well as the fantasy life the right image can supply. There is nothing wrong with having an image, everyone portrays an image whether they like it or not. In this case the problem is, MTV uses image to sell a product where image should be considered irrelevant. The effect of doing this is closing the viewers’ minds; it causes people to listen to music only on the expressional level.
Memory capacity

1. Imagery (I). Although I is most often discussed in terms of visual examples, it is not exclusively a visual phenomenon. Auditory I is clearly illustrated by one’s mental response to request’’think of the sound a cow makes’’. Olfactory I occurs when we imagine the smell of a Thanksgiving turkey cooking in the oven; this can be followed by taste I imagining how it would taste. When we imagine the touch of another person we use tactile I. I is quite frequently used as a means of encoding information for transfer to LM. The more the ways information is encoded the more cues we will find so it will lead to better retrieval.

Mass media
2009-12-22
Good morning, today I`m going to speak about ‘Mass media’. To start with, the mass media play an important part in our lives. Newspapers, radio and especially TV inform us of what is going on in this world and give us wonderful possibilities for education and entertainment. They also influence the way we see the world and shape our views. Of course, not all newspapers and TV programmes report the events objectively but serious journalists and TV reporters try to be fair and provide us with reliable information. It is true that the world today is full of dramatic events and most news seems to be bad news. But people aren't interested in ordinary events. That is why there are so many programmes and articles about natural disasters, plane crashes, wars, murders and robberies. Good news doesn't usually make headlines. Bad news does. To my mind say that journalists are given too much freedom. They often intrude on people's private lives. They follow celebrities and print sensational stories about them which are untrue or half-true. They take photos of them in their most intimate moments. The question is — should this be allowed? The main source of news for millions of people is television. People like TV news because they can see everything with their own eyes. And that's an important advantage. Seeing, as we know, is believing. Besides, it's much more difficult for politicians to lie in front of the cameras than on the pages of newspapers. As far as can see, many people prefer the radio. It's good to listen to in the car, or in the open air, or when you do something about the house. In addition, other scours of information are newspapers. The best known are `Lietuvos rytas` and citizens  of Kaunas read `Kauno diena`. These concern themselves, as far as possible, with factual reports of major national and international news stories, with the world of politics and business and with the arts and sport. Newspapers don't react to events as quickly as TV, but they usually provide us with extra detail, comment and background information. The Internet has recently become another important source of information. It is believed that in the year of 2010 there will be at least 500 million people on the system enjoying virtual reality. It means that more and more people use Internet for searching the news instead of reading newspapers or watching news on Tv. Its main advantage is that news appears on the screen as soon as things happen in real life and you don't have to wait for news time on TV. Thanks to Internet now news are easy of access. To sum up, mass media reach very large numbers of people. For this reason it plays a significant role in our lives. More than even before, mass media offers us a window to the world and it depends only on you which scours of information to choose.

Genetic engineering
2009-12-22
It is estimated that humans have between 50,000 to 100,000 different genes; some of them are linked to particular diseases and conditions. Scientists have now identified nearly 4000 conditions that are limited to single defects in a person’s genetic code. Researchers all around the world are currently engaged in “The human genome project”, which aims to identify and define the function of every gene to be found in the human body. Through this they hope to locate errant genes, thereby getting a better understanding of every disease that is genetically transmittable and if possible find a cure for it. Genetic engineering, where by the defective gene sequence is cut and remodeled, is one route scientists might take. At present genetics can be a reliable predictor of who is likely to develop a particular fatal illness. Many feel that this information has the potential to cause as much harm as good, among the 10 percent of the population who may be affected. Some say that people would not be able to cope with the knowledge that they were likely to contract a terminal illness, but genetics argue that everyone has the right to know so that they could plan the rest of their lives. Some women who have been told that they are likely to develop breast cancer have chosen a surgery to remove the breast in order to increase their chances of survival. Genetic engineering is big business, and many experiments take place on animals. Fruit flies have been produced that they have extra eyes on their wings and legs; two years ago scientists grew an ear in a test tube and then transplanted on a laboratory mouse without immune system in order to see if it would be rejected. Harvard University has even patented its own mouse known as “nocuous” which has been genetically manipulated to develop cancer. Imutran, a Cambridge-based biotechnology firm, have produced a pig that is transgenic, from which they hope to be able to supply donor organs such as hearts that are in short supply for transplantation. The revelation that scientists at Cambridge University have successfully transplanted the hearts from genetically altered pigs into monkeys is the most wonderful news to have emerged from the world of medicine fro more than a decade. We are all to familiar with the bad side of science – here is a cause for being happy. The implications are stunning. We are witnessing the forward in human happiness. The chance now exists that hundreds of thousands of people, who are waiting for heart, liver and kidney transplants and would die because of the lack of donors, will now live. Suffers from many other diseases will also face hope. Not only will all those who need these major organ transplants be treated but whole new therapies will emerge. Many cancers, for example are now treated by chemotherapy or radiotherapy but in future it might be safer and more effective to just transplant the affected organ. Possibilities are nearly endless and truly amazing. Whole new era of health and longevity is now downing. Names of diseases: Appendicitis, bronchitis, cancer, chicken-pox, constipation – vidurių užkietėjimas, diabetes, diarrhoea – viduriavimas, hay fever – šienligė, hepatitis, indigestion – skrandžio skausmai, flu, insomnia – nemiga, leukaemia, measles – tymai, mumps – kiaulytė, tonsillitis – angina. Shortened one: Genetic engineering A general term for the direncted manipulation of genes, and usually used synonymously with genetic manipulation or genetic modification. A wide range of technologies are involved in this, but most involve the recombinant DNA techniques. Genetic engineering falls into several different categories depending on what is being engineered. Bacteria, yeast. This is ‘traditional’ genetic engineering (over 10 years old). Using recombinant DNA techniques genes are put into microorganisms to make them produce something we want, be it insulin, better beer or protein for food. Animals. Genetically engineered animals are usually called transgenetic animals. They are produced by a combination of fertilization techniques and DNA technology and produce animals that pass on their genetic modification to their offspring. Plants. Sometimes called transgenetic plants. They are created through the use of plant cloning technologies, which involve growing plants from isolated plant cells. Humans. Although the genetic engineering methods applicable to cows or mice are, in theory, applicable to humans, they have not been yet applied for obvious ethical reasons. Some experiments treating disease have been performed: these do not modify the germ cells. This is called gene theraphy rather than more public allarming term genetic engineering.

Drink and food
2009-12-22
Approximately ten years ago there was a day when I had nothing to do and fortunately I found a cooking book. It was old German cooking manual with the nice pictures. Although I could not read German but the pictures were very informative. After few hours my kitchen looked as a ruin and all food-stuff was damaged. In spite of this I have become an enthusiastic cooking fan. Since then my cooking knowledge and experience has improved a lot. Now I specialize in cold meal especially in salad and sandwiches. In fact to make cold snacks you do not need much time and preparation. My favorite salad is made from walnuts and rise. On weekends or holidays I make dinner for my girlfriend or family. Trout in lemon and white vine sauce I cook the best. Several years ago I have begun to use vines as an ingredient of my dishes. Therefore I analyzed many sorts of it. Furthermore vines are very good addition to meal. I drink white vines while I am eating fish and in my minds eye the best choice is Merceau bur it is expensive and rare. More often I drink Chateau du Paper. With meet I prefer red vines such as Pomerol, red Burgundy and red Bordo. Cooking is good and interesting hobby. No doubt it is beneficial to know how to make food because you never know what kind of woman you would get.
Dental caries
2009-12-22
Alternative names: dental cavities; tooth decay. Definition: A disease of the teeth resulting in damage to tooth structure. Dental caries is one of the most prevalent disorders afflicting mankind, second only to common cold. It usually occurs in children and young adults. Dental caries is a relatively recent in human history. Dental caries remain a relatively rare disease in some areas of the world. In Europe, North and South America, virtually every person is attacked at some time during his life. Tooth decay seems to be a disease of civilization possibly associated with refined foods. A lack of dental cleanliness is also closely associated with tooth decay. There are three main factors that be simultaneously for the condition to occur: ●microbial dental plaque; ●teeth susceptible to caries; ●diet that provides a frequent supply of fermentable carbohydrate Microbial dental plaque is a colorless, bacteria laden film that forms daily on the teeth. The bacteria convert all foods-especially sugar starch-into acids. The onset of carries is early in susceptible populations. Decay occurs where bacteria and foods adhere to the surface of the teeth. Many individuals with high caries susceptibility speak of inheriting “soft teeth” or that the resistance to tooth decay is strongly influenced by genetic variation in tooth composition. Prevention. Oral hygiene is the primary prevention against dental caries. This consists of personal care and professional care. The use of dental sealants is a good means of cavity prevention. Sealants are thin plastic-like coatings applied to the chewing surfaces of the molars. Symptoms and Signs: ● toothache; ● cavities. Most dental caries are discovered in the early stages during routine checkups. The surface of the tooth may be soft, pain may not be present until advanced stages of tooth decay and dental X-ray may show some cavities before they are visible. Treatment. Destroyed tooth structure does not regenerate. The progression of dental caries can be stopped by treatment. In filling teeth, the decayed material is removed by drilling and replaced with a restorative material such as silver alloy, gold, porcelain, or composite. Treatment often preserves the tooth.

Speciality The new thing that this store has is minimal inventory. Most probably many have said this before but they all still work under the old idea that all the records have to physically be in the store when the customers want to buy them. By taking the model of Apple's iTunes Store and moving it out of the home and onto the streets we can achieve a much lower inventory than is possible with a traditional musicstore. All the music would be stored on computer drives in full quality and when the customer wants to buy an album he simply requests it from the salesman who burns the album on a cd which the customer then takes with him. With this comes a much higher computer cost but that is more than balanced out by less inventory and less requirements for the store's size plus we get the added bonus of a potentially strong online presence. The stock-reducing feature of this store can be described so that no cd´s will be bought from the publishers except those that have already been sold. It would work similar to when one orders a cd from a traditional music store. The process then is that they put in an order for that particular cd which is then sent to them in the next shipment. Since they already can sell it when it comes to the store no cost of stock needs to be accredited to that particular cd and it will not degrade in value, as it remains unsold in the store. Market In all probability it will be easier to get smaller independent labels to accept this new arrangement since they are often less concerned about piracy and illegal distribution of their music. When Apple introduced its online record store with the possibility of burning song to cd it may have broken the ice for big publishers who may see this opportunity for what it really is, a big chance for them to regain some control over music distribution. According to the financial calculations presented in Appendix C we need to sell 22 cd's per day 30 days a month to get just above the break even point. That should be a reachable goal as we see with the following logic. For a store in central Reykjavik we can assume that the market size is 1800 customers. That is 10% of the population between 15 and 30. So in order to reach the breakeven point every customer needs to buy 4.4 cd’s per year, a goal that is easily within reach considering usual spending habits of young people in Iceland. A threat to this is of course the Internet and illegal downloads of music. Market size is furthermore considered under three circumstances, low, medium and high with the sales numbers 10, 40 and 100 respectively. The probability for each demand is 0.6, 0.3 and 0.1. A great factor in why low market size is thought to be most probable is the Internet and the still growing popularity of illegal downloads. Setup For a breakdown and projection of Setup cost see Appendix A. The setup for such a store is more like what one would expect from an ISP rather than a record store because servers and large data storage facilities will be prominent factors of the startup cost. Another aspect is the cost expected to be needed to ensure proper license agreements with publishers. That amount is expected to be needed for travel expenses and other costs excluding legal expenses that will arise from negotiating with the publishers about this new form of sales. Legal expenses are marked as a special cost category because of the difference in tax issues between these two factors in Iceland. Special programs will be needed in the modern store while traditional stock and bookkeeping software can be used in the traditional store. Among this special software is cd burning software, server maintenance and control as well as possible software to report sales of cd´s to the publishers but that will depend on the deals made with them, i.e. if they want secure data directly from the computer system without human interaction or if they simply want a report based on honesty for their billing purposes. In the financial calculation it has been assumed that just about all startup expenses will be covered by loans and that those loans will be fully repaid in three years. This is done to provide a horizon for the comparison. Operating Cost Operating cost projections are presented in Appendix B Operating cost for the two stores is calculated without considering inflation because it is not customary to consider inflation in such calculations. It is assumed that any change in costs will be carried directly into the prices and therefor effectively negating all consequences. The expected sale used in Replenishment of stock is 10% of the stock. This is below the breakeven point but since the breakeven analysis with NPV uses the sales as a variable this has no effect on that. The main objective with the operating cost sheet is to get a rough idea of what forms the operating expenses and approximate the amount. Legal expenses and publishing are assumed to be evenly distributed over the period while in fact they would be discrete and uneven amounts. For this preliminary analysis the even distribution is accurate enough. Payments of loans are expected to be every three months and the interest rate is 6% per year. The payments are assumed to be equal payments. Break Even Analysis When NPV is calculated it is assumed that the business is worthless at the end of three years and therefor we get no return at the end of that period. Interest rate is set to approximately 25% per year or exactly 2% per month. This interest rate is our interest demand, that is the interest we expect to be able to get if we invest differently. When establishing the Break Even point NPV analysis is used with the Goal seek option in Excel. The NPV is set to 0 and Goal seek adjusts the sales to find the corresponding amount. This is different from finding the breakeven for individual months or the sum of the period in general because this takes into account the possible earning of the money if it was invested differently. The Break Even analysis is presented in Appendix C. Results After examining the numbers we see that the modern store has a definite advantage over the traditional approach. By arranging the decision matrix and using the Maximax or MiniMax methods to determine the best possibility we get the same results, the modern store has better potential than the traditional one with regards to the NPV calculations. Furthermore if we use Expected Return, that is multiply the probabilities and return and then taking the maximum of that we get the same result. In the market section we saw a logical induction for the market share reaching and probably overtaking the breakeven point of 22cd's for modern store. The breakeven for a traditional is 59cd's and that amount we can not expect without a high demand which is considered improbable. Recommendations It is necessary before making any commitments regarding the store to first look for further information about the Apple deal. That information might be found on Internet rumor pages or magazines and newspapers covering the iTunes store. What we need to find out is any conditions that publishers put forth and the problems encountered on the way as well as how much Apple needs to pay the publishers for every song they sell, that should establish a baseline for the prices because it is unlikely that a small store like this would get a better deal than an industry giant with a phenomenal track record. A market analysis needs to be conducted. It can be as simple as sitting outside a competing record store and counting the number of people coming out of it with a bag in their hand or it can be a full third party analysis of the market. But making some kind of market research is important for further establishing the estimates of market size. With respect to the expected market size it is needed to determine the amount of cd writing equipment is needed. This is a variable with no counterpart in the traditional store but the potential of being quite expensive depending on the expectations of the stores client with regard to speed of service. It is necessary to examine many possible solutions ranging from cheap personal cd writers to more advanced professional equipment. Another such issue is the servers that store the music. They need to be able to store large amounts of data and need to serve all the data to the cd writers when it is requested. That should actually not be a big problem since modern servers have a very high bandwidth. Another issue that needs to be considered is the financial aspect. It is not very wise to finance the preparation expenses with loans, one should rather try to get venture capital or finance it in other ways. A loan can be a big burden to bear if it turns out that publishers are not willing to allow this form of store but the venture capital would simply be lost without much consequence. With venture capital the control of the store is in lost to some extent but that could be more feasible than to be stuck with payments of a loan that generated zero income.

Business
2009-12-22
More and more people are beginning to open new business ventures (sumanymas). It seems like it is becoming the popular move. By opening a business there could be big profit(nauda)to be made, depending(atsizvelgiant) on the market. On the other hand, there are risks(rizika). It is said that there are two reasons why people start a business. The first reason is because they have inspiration(ikvepimas) for what they believe would be a great idea and the second is from desperation(neviltis).. There are various different ways to start a business. Not all entrepreneurs(verslininkai) begin their business by the thought of an idea. There are many other ways to go about starting a business. Buying a franchise, buying an existing company, the inventions of a product are all other ways to begin a business. People often start a business in a field that they know well. Although this is true, it is important not to limit the perspectives(perspektyva) of the kind of business to open. The areas outside of your interests may just be the right opportunity(galimybe) for you, which is why it is important to explore(istirti)other areas. This paper will talk about the general ways in which to start a new business and how to go about doing it. Included will be how to get ideas to open a business, planning out the business structure, ways to get money to start the business, getting prepared(pasiruosimas), hiring(samda the staff, and getting the word out to the public. Getting ideas to Open a Business the business idea plays a critical role in the overall(apskritai) success of the business venture chosen.. There are many considerations(pamastymu) that must be thought of before determine(nulemti) the success of an enterprise, including the entrepreneur, financing and other external forces. In order to have a good business idea it should:  satisfy personal goals and interests, (patenkinti personalo tikslus ir..)  find a success place in the market,  making sure it is possible to produce the necessary quality of the product or service,  Meet or exceed your financial goals.(atitikti ar virsyti ) In order to meet all of these criteria, it is important to complete research(uzbaigti nagrinejima) on the business idea that has been chosen. Research information can be gathered(kauptas) from various different sources(saltiniu). Some of these sources being the library, looking at existing businesses, word of mouth, reading books, watching television, going to government departments, talking to university professors etc. If the research has not been completed then it more likely that the business will become a failure(bankrotas) Planning out the business structure The one basic question facing all new business owners is “what business structure is the best for me?”. There are three main types of business structures:  sole proprietorship, (private nuosavybe)  partnership,(kompanija partneryste)  corporation. All of these different structures are different and require(reikalauja) different things to make them work. The sole proprietorship is a business that has only one owner and for the purpose of his/her own profit, the partnership is a business which has two or more people and all of the workers work as co-owners(bendra nuosavybe), and the corporation is an artificial entry with obligations(netikras iejimas su isipareigojimais Ways to Get Money to Start the Business There are various different funds available for new business ventures to try and create more jobs. Entrepreneurs are more then welcome to come into economy. To get these funds the business plan has to be completed. The funds available are for many different types of people. There are special ones for immigrant entrepreneurs, women’s entrepreneurs, and young entrepreneurs. Loans(paskola) from the government are available in several different places. The loans from the Government are mostly interest free and unsecured(negarantuotas) loans. This, in comparison(palyginus) to a bank loan, is much better for the fact that there is no interest. If the only opportunity left is the bank then it is necessary to get a low interest loan. When there is the most common questions in starting a business is: “where do I start?”. The questioner below will help answer that question for new business people. This checklist (katakogas) will be the road map for starting a business. Most business owners should use this to make sure that everything is done before the opening of the store. Prepare a business plan. Prepare a marketing plan.

American English speaking without a lot of effort How To Learn American English Speaking Easily? Everyone learns to speak their native language. Is there some things that kids are missing when they are emerging? Dr. J. Marvin Brown says that “both adults and children can do it right, but only adults can do it wrong.” So why we can not use the same approach with a second language? Why we can’t learn American English speaking like children? Easily and without a lot of effort. In fact we can. There are a lot of researches which shows that adults can learn languages even more easily and fast. But here‘s the thing. We need forget all that we were learning in school. Because it is the most important reason why we can not speak American English at all. That’s the reason why we don’t understand anything when American people are talking to each other. Yes, we can read American and English newspapers, but this language is not the same. The people are not speaking that way. Their speech is different. If we want to understand native American speakers and speak with them, we must find the different way. In 1984, the American University Language Center in Bangkok started using a new approach to teach the Thai language. The method is known as “Automatic Language Growth”. The first mistake they noticed is that adults are trying to speak in new language to early. They don’t have enough exposure to language yet and they are struggling and feel uncomfortable. They are bringing patterns from their first language and later they are speaking with a strong accent. Children in the beginning are just listening to the new language. They starts to speak when they are prepared. That’s the big difference. The second mistake adults make is that they are thinking, that they must study grammar. That’s a huge mistake. A vital mistake. Children do not studying grammar and that’s the key. If we want to learn American English speaking we must learn speaking. Not grammar. Learning grammar does not make you fluent. You must train your ears and you must train your mouth. So how we can learn speaking without grammar. Simply. First of all we must listen. Every day one or two hours. The more is the best. We must listen to easy and understandible content. That builds our confidence. And we must begin to speak when we are prepared only. When we can do this without struggling. It commes authomatically. Believe me. I have done this with Original Effortless English Lessons. It is totally new approach in learning English. It is real language. You can learn English speaking naturally. You can do the same. You can learn American English speaking just like I did.

Alcoholism
2009-12-22
More males than females are affected by alcoholism, but drinking among the young and among women is increasing. Consumption of alcohol is apparently on the rise in the United States, as is the total alcohol consumption and prevalence of alcohol-related problems in the former communist countries of Eastern Europe and the former Soviet Union. This increase is paralleled in other countries, including developing nations. After 1980, however, consumption remained relatively stable in many western European nations. Alcoholism, as opposed to merely excessive or irresponsible drinking, has been thought of as a symptom of psychological or social stress or as a learned, maladaptive coping behaviour. More recently, and probably more accurately, it has come to be viewed as a complex disease in its own right. Alcoholism usually develops over a period of years. Alcohol comes to be used more as a mood-changing drug than as a foodstuff or beverage served as a part of social custom or religious ritual. Initially, the alcoholic may demonstrate a high tolerance to alcohol, consuming more and showing fewer adverse effects than others. Subsequently, however, the person begins to drink against his or her own best interests, as alcohol comes to assume more importance than personal relationships, work, reputation, or even physical health. The person commonly loses control over drinking and is increasingly unable to predict how much alcohol will be consumed on a given occasion or, if the person is currently abstaining, when the drinking will resume again. Physical addiction to the drug may occur, sometimes eventually leading to drinking around the clock to avoid withdrawal symptoms. Effects Alcohol has direct toxic as well as sedative effects on the body, and failure to take care of nutritional and other physical needs during prolonged periods of excessive drinking may further complicate matters. Advanced cases often require hospitalization. The effects on major organ systems are cumulative and include a wide range of digestive-system disorders such as ulcers, inflammation of the pancreas, and cirrhosis of the liver. The central and peripheral nervous systems can be permanently damaged. Blackouts, hallucinations, and extreme tremors may occur. The latter symptoms are involved in the most serious alcohol withdrawal syndrome, delirium tremens, which can prove fatal despite prompt treatment. This is in contrast to withdrawal from narcotic drugs such as heroin, which, although distressing, rarely results in death. Recent evidence has shown that heavy—and even moderate—drinking during pregnancy can cause serious damage to the unborn child: physical or mental retardation, or both; a rare but severe expression of this damage is known as foetal alcohol syndrome. HISTORY OF ALCOHOL Thousands of years ago people began to make alcohol for practical reasons. Wine making began with the early Egyptians who found that grape juise spoiled quickly,but that fermented juise or wine would keep without spoiling.They also had problems with impure water,and the Egyptians noticed that people did not sick ower wine,but they often became ill when they drank inpure water.In later years,wine became inportant to the Roman Catholic Church throughuot Europe because wine was used to celebrate the sacrament of the Mass.By the 1300`s,beer industry had emerged in Central Europe.At this time,wine was also continuing to grow in popularity;many brands named for the places in which they originated.At first alcohol was desined for the practical reasons,its use changed.People began to experiment with different types of alcohol.Alcohol became an integral part of European culture.We need to understand the harmful effects of alcohol,because it can be fatal.
Agoraphobia
2009-12-22
These people avoid being on busy streets or in crowded stores, theatres and churches. Normal activities become restricted as the person avoids these situations. Many agoraphobia victims are afraid of leaving the house. Perhaps for this reason agoraphobia is the most common phobia seen in the clinic, about 60% of all examined phobias. Agoraphobia occurs about two times more commonly among women than men. It can be connected with the fact, that Women have been and are still being stereotyped, agoraphobia has been explained in terms of traditional sex roles. Clinical descriptions of agoraphobics use such words as passive, shy, dependent, descriptions traditionally applied to women. It may be as Fodor suggests, that being agoraphobic, is in part a logical, although exaggerated, extension of the stereotyped female role. Until recently and still in many societies it has been more acceptable for a woman than for a man to be housebound. As stereotypes of womes as helpless, fragile, home-oriented, passive, fearful and dependent will change, the should be equal number of male-female agoraphobics. The disorder tends to be more common among families where other members also suffer from an anxiety disorder and/or possibly abuse alcohol. Most agoraphobia’s develop symptoms between the ages of 18 and 35. The onset may be sudden or gradual. Many agoraphobia victims develop the disorder after first suffering a series of panic attacks in public places. The attacks seem to occur randomly and without warning, making it impossible for a person to predict what situation will trigger such a reaction. Attack is accompanied with tension, anxiety, dizziness, depression, sweating, more frequent heartbeating, minor checking compulsions – checking is the door is locked, no intruder is under the bed, the iron is offf- rumination and fear of going mad. One study found that 93% of agoraphobics also reported fears of heights and enclosed spaces such as subways and elevators. But many agoraphobics have “good days”, when they can move about. Being with a trusted companion can also help them leave the house. Treatment Fortunately, phobias are very treatable. In fact, most people who seek treatment completely overcome their fears for life. Psychoanalytic approaches. Treatment tries to uncover the repressed conflict, that are thought to be covered in the extreme fear and avoidance. Phobia is thought to protect the person from repressed conflicts that are too painful to face it. There are two major techniques, that are used to help lift the repression. First is – free association. The analyst listen carefully to what tha patient mentions in connections with any references to the phobia. And second – analyst tries to discover origins of the phobia by analyzing the content of dreams. But more effective relief can be gained through either behavior therapy or medication. In behavior therapy, one meets with a trained therapist and learns to control the physical reactions of fear. The person first imagines the feared object or situation, works up to looking at pictures that show the object or situation, and finally actually experiences the situation or comes in contact with the feared object. the person becomes accustomed to it and can lose the terror, horror, panic, and dread he or she once felt. It is called systematic desensitization. Medications are used to control the panic experienced during a phobic situation as well as the anxiety aroused by anticipation of that situation and are the treatment of first choice for social phobia and agoraphobia. Any phobia that interferes with daily living and creates extreme disability should be treated. With proper treatment, the vast majority of phobia patients can completely overcome their fears and be symptom free for years, if not for life.
Acid rain
2009-12-22
. On both sides of the border, cars and trucks are the main sources for nitric acid(about 40% of the total), while power generating plants and industrial commercial and residential fuel combustion together contribute most of the rest. In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre©Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic one. This is why many lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced substantially. ACID The average mean of pH rainfall in Ontario's Muskoka©Haliburton lake country ranges between 3.95 and 4.38 about 40 times more acidic than normal rainfall, while storms in Pennsilvania have rainfall pH at 2.8 it almost has the same rating for vinegar. Already 140 Ontario lakes are completely dead or dying. An additional 48 000 are sensitive and vulnerable to acid rain due to the surrounding concentrated acidic soils.Ô ACID RAIN CONSISTS OF....? Canada does not have as many people, power plants or automobiles as the United States, and yet acid rain there has become so severe that Canadian government officials called it the most pressing environmental issue facing the nation. But it is important to bear in mind that acid rain is only one segment, of the widespread pollution of the atmosphere facing the world. Each year the global atmosphere is on the receiving end of 20 billion tons of carbon dioxide, 130 million tons of suffer dioxide, 97 million tons of hydrocarbons, 53 million tons of nitrogen oxides, more than three million tons of arsenic, cadmium, lead, mercury, nickel, zinc and other toxic metals, and a host of synthetic organic compounds ranging from polychlorinated biphenyls(PCBs) to toxaphene and other pesticides, a number of which may be capable of causing cancer, birth defects, or genetic imbalances. COST OF ACID RAIN Interactions of pollutants can cause problems. In addition to contributing to acid rain, nitrogen oxides can react with hydrocarbons to produce ozone, a major air pollutant responsible in the United States for annual losses of $2 billion to 4.5 billion worth of wheat, corn, soyabeans, and peanuts. A wide range of interactions can occur many unknown with toxic metals. In Canada, Ontario alone has lost the fish in an estimated 4000 lakes and provincial authorities calculate that Ontario stands to lose the fish in 48 500 more lakes within the next twenty years if acid rain continues at the present rate.Ontario is not alone, on Nova Scotia's Eastern most shores, almost every river flowing to the Atlantic Ocean is poisoned with acid. Further threatening a $2 million a year fishing industry. Ô Acid rain is killing more than lakes. It can scar the leaves of hardwood forest, wither ferns and lichens, accelerate the death of coniferous needles, sterilize seeds, and weaken the forests to a state that is vulnerable to disease infestation and decay. In the soil the acid neutralizes chemicals vital for growth, strips others from the soil and carries them to the lakes and literally retards the respiration of the soil. The rate of forest growth in the White Mountains of New Hampshire has declined 18% between 1956 and 1965, time of increasingly intense acidic rainfall. Acid rain no longer falls exclusively on the lakes, forest, and thin soils of the Northeast it now covers half the continent. EFFECTS There is evidence that the rain is destroying the productivity of the once rich soils themselves, like an overdose of chemical fertilizer or a gigantic drenching of vinegar. The damage of such overdosing may not be repairable or reversible. On some croplands, tomatoes grow to only half their full weight, and the leaves of radishes wither. Naturally it rains on cities too, eating away stone monuments and concrete structures, and corroding the pipes which channel the water away to the lakes and the cycle is repeated. Paints and automobile paints have its life reduce due to the pollution in the atmosphere speeding up the corrosion process. In some communities the drinking water is laced with toxic metals freed from metal pipes by the acidity. As if urban skies were not already grey enough, typical visibility has declined from 10 to 4 miles, along the Eastern seaboard, as acid rain turns into smogs. Also, now there are indicators that the components of acid rain are a health risk, linked to human respiratory disease. PREVENTION However, the acidification of water supplies could result in increased concentrations of metals in plumbing such as lead, copper and zinc which could result in adverse health effects. After any period of non©use, water taps at summer cottages or ski chalets they should run the taps for at least 60 seconds to flush any excess debris. Ô STATISTICS Although there is very little data, the evidence indicates that in the last twenty to thirty years the acidity of rain has increased in many parts of the United States. Presently, the United States annually discharges more than 26 million tons of suffer dioxide into the atmosphere. Just three states, Ohio, Indiana, and Illinois are responsible for nearly a quarter of this total. Overall, twoªthirds of the suffer dioxide into the atmosphere over the United States comes from coal©fired and oil fired plants. Industrial boilers, smelters, and refineries contribute 26%; commercial institutions and residences 5%; and transportation 3%. The outlook for future emissions of suffer dioxide is not a bright one. Between now and the year 2000, United States utilities are expected to double the amount of coal they burn. The United States currently pumps some 23 million tons of nitrogen oxides into the atmosphere in the course of the year. Transportation sources account for 40%; power plants, 30%; industrial sources, 25%; and commercial institutions and residues, 5%. What makes these figures particularly distributing is that nitrogen oxide emissions have tripled in the last thirty years. FINAL THOUGHTS Acid rain is very real and a very threatening problem. Action by one government is not enough. In order for things to be done we need to find a way to work together on this for at least a reduction in the contaminates contributing to acid rain. Although there are right steps in the right directions but the government should be cracking down on factories not using the best filtering systems when incinerating or if the factory is giving off any other dangerous fumes.
About languages (apie kalbas) My native language is Lithuania. So he must know its history, grammar, literature spelling. When I was on the fourth form I began to learn the English language. From the very first days I understood that it is very difficult to learn. English, as it has different pronunciation and spelling. If you want to learn new words, grammar, how to form the sentence. It is necessary to know the history, culture, traditions of the country which language, you study. It is very difficult to learn any foreign language when you do not hear it in the street at house. The film which we see on TV are translated into native language and we can’t hear the English language. The English language is very popular in the world and what country you visit you can communicate in England. The role of the foreign languageshas inereased in the last years, as Lithuanian keeps good relations with other European countries and is going to biome a member of European Union and NATO. So every young person must think about his future and the use of the foreign language. The European Union(apie europos sąjungą) The European Union is the European supranational organization dedicated to increasing economic integration and strengthening co-operation among its member states. The European Union was established on November one, nineteen ninety three. The treaty on European Union was ratified by the twelve members of the European community. They were Belgium, Denmark, France, Germany, Great Britain, Greece, Ireland, Italy, Luxemburg, the Netherlands, Portugal and Spain. The citizen of the European Union countries received the right to immigrate From owe country to another and they got a greater freedom to live, work or study in any of the member states and there were no borders to travel from are European Union State to another. The main body of the European Union is the European Parliament, which is elected by the citizens of the European Union States. The main body works in Strasburg, but most work of its committee is done in Brussels. Finland, Austria and Sweden joined the European Union in nineteen ninety five. In this year May first day Lithuania, Estonia and Latvia will become the members of the European Union. There are seven other countries which will become the members of the European union. They are: Poland, Cheek, Cyprus, Malta, Hungary, Slovakia, and Slovenia. About myself(apie save) My name is Justina and surname is Šaučiūnaitė. I live in Anykščiai in Stoties street No eleven. I was born on the fiveof march nineteen eighty six in Anykščiai. I am eighteen, I am the citizen of Lithuania.

Pollution problems
2009-10-09
Today pollution is very important problem in the world. What we can see on television, or hear on the radio about our environment is only wishful thinking, because in the real life, around us, there is lots of rubbish, water is unhealthy and air is not very clean. People drop litter around and they don’t think about consequences. We should take thought about saving the environment, because it is one of the biggest gifts of the life.

William Shakespeare was born to John Shakespeare and mother Mary Arden some time in late April 1564 in Stratford-upon-Avon. There is no record of his birth, but his baptism was recorded by the church, thus his birthday is assumed to be the 23 of April. His father was a prominent and prosperous alderman in the town of Stratford-upon-Avon, and was later granted a coat of arms by the College of Heralds. All that is known of Shakespeare's youth is that he presumably attended the Stratford Grammar School, and did not proceed to Oxford or Cambridge.
