Addictions Addiction has been defined as physical and psychological dependence on psychoactive substances (for example alcohol, tobacco, heroin, caffeine and other drugs) which cross the blood-brain barrier once ingested, temporarily altering the chemical milieu of the brain. Drug addiction Drug addiction can simply be defined as a "chronic relapsing disorder characterized by persistent drug-seeking and drug-taking behaviours". Drug addiction is chronic, with no known cure. Controlled may be by means such as voluntary 12 step programs, group therapy, one on one therapy, and mandatory methadone maintenance
Have you ever come home from school, practice or whatever and felt soooo thirsty? So you walk towards the fridge and hope there's something cold to drink. You open the door of the fridge and start to smile, because you have seen a bottle of COCA-COLA!! Coca- Cola is a carbonated soft drink sold in stores, restaurants and vending machines throughout the world. It is produced by The Coca-Cola Company and is often known as Coke. The Coca-Cola Company has introduced other cola drinks under the Coke brand name. The most famous of these are Coca-Cola Zero, Coca- Cola Light and Coca-Cola Cherry. Based on Interbrand's best global brand 2011, Coca-Cola was the world's most valuable brand. It was 1886, and in New York Harbour, workers were constructing the Statue of Liberty. But 800 miles away, in Atlanta, Georgia, another great American symbol was about to be come into being. When Coca-Cola was invented by pharmacist John Pemberton, it was originally
You've probably heard that drugs are bad for you, but what does that mean and why are they bad? Medicines Are Legal Drugs If you've ever been sick and had to take medicine, you already know about one kind of drugs. Medicines are legal drugs, meaning doctors are allowed to prescribe them for patients, stores can sell them, and people are allowed to buy them. But it's not legal, or safe, for people to use these medicines any way they want. Cigarettes and Alcohol Cigarettes and alcohol are two other kinds of legal drugs. (In Estonia, adults 18 can buy cigarettes and alcohol.) But smoking and excessive drinking are not healthy for adults and off limits for kids. Nicotine is the drug in tobacco leaves. Whether someone smokes, chews, or sniffs tobacco, he or she is delivering nicotine to the brain. Each cigarette contains about 10 milligrams of nicotine. Nicotine is what keeps people smoking despite its harmful effects. Because the
To most people alcohol is considerd a downer that reduces activity in the nervous system. Some of the things alcohol effects you is, the alcohol intoxicated person exhibits lose muscle tone, loss of fine moter coordination,and often has a staggering "drunken" gait. The eyes may appear somewhat "glossy" and pupils may be slow to respond to stimulus. At high doses pupils may become constricted. At intoxing doses, alcohol can decrease heart rate, lower blood pressure and respiration rate, and result in decreased reflex and slower reaction times. Skin may be cool to touch but to the user may feel warm or normal, profuse sweating may accompany alcohol use. Loose muscle tone, lose of fine motor coordination,odor of alcohol on the breath,and a stagging "drunken"gait. The effects of alcohol intoxication are greatly influenced by individual variations among users. Some users may become intoxicated at a much lower Blood Alcohol
So why do people start doing it in the first place? Firstly sometimes people try their first cigarette, they like it and so they start doing it more regularly. Secondly some people start smoking because there's a rumour saying that it's slimming. And another reason may be that it may relieve stress. After three or four cigarettes you get addicted to it because of nicotine. It is a drug that stimulates the brain. When the level of nicotine falls in your blood and you're a regular smoker, you usually develop withdrawal symptoms, such as craving, anxiety, restlessness, headaches, irritability, hunger, difficulty with concentration, or just feeling awful. These symptoms are relieved by the next cigarette. Most smokers need to smoke regularly to feel normal and to prevent nicotine withdrawal symptoms. So once you start smoking it is very hard to quit. But why is smoking so harmful? Cigarettes have tar in them which contains many chemicals
Psychology Gleitman Blood flow in the brain during different activities: the rate of blood flow is measured by special radiation counters that are placed at various points of the skull and that monitor radiation from mildly radioactive gas injected into the bloodstream. Blood flow pattern depends on what the patient does ( different pattern is found when person is reading aloud, yet another when he watches a moving light and so on). Ambiguous sights and sounds: The way ambiguous figures are perceived often depends on what we have seen just before. For example, if we are first shown an unambiguous figure of a rat, the ambiguous picture will be seen as a rat. If we are first exposed to an unambiguous face, we see the ambiguous figure as a face.

Short and long term effects of alcohol Good morning. My name is NIMI. I'm going to talk about short and long term effects of alcohol consumption. Firstly I'll tell you about short term effects and then move on to long term effects. My presentation will take about 5 minutes. If you have any questions, you are welcome to ask them afterwards. Firstly I would focus on the short term effects of alcohol consumption. The amount and circumstances of alcohol consumption play a large part in determining the extent of intoxication; for instance, consuming alcohol after a heavy meal causes alcohol to absorb more slowly. Hydration also plays a role as for determining the extent of hangovers. Initially, alcohol produces feelings of relaxation and cheerfulness, but as a result of further consumption blurred vision and coordination problems generally occure. As far as cell membranes are concerned they are highly permeable to alcohol, once alcohol is in the
Extended Essay Research Question: To What Extent Does a Plant Based Diet Lower the Risk of Coronary Artery Disease? Subject: Biology Word Count: 3482 Abstract: Because there has been much debate over whether plant based diets are beneficial or not, I’m willing to learn more about it and since there’s eligible data available on the effects of vegetarian/vegan diets on cardiovascular diseases, my research question is formed accordingly: To what extent does a plant based diet lower the risk of coronary artery disease? The importance of this study lies in my own curiosity and my desire to acquire further knowledge on the prevention and treatment of coronary artery disease.
Formaldehyde Formaldehyde is a colorless, flammable gas at room temperature. It has a pungent, distinct odor and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. Formaldehyde is also known as methanal, methylene oxide, oxymethylene, methylaldehyde, and oxomethane. Formaldehyde can react with many other chemicals, and it will break down into methanol (wood alcohol) and carbon monoxide at very high temperatures. Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin. A major source of formaldehyde that we breathe every day is found in smog in the lower atmosphere. Automobile
information of the components of human behavior in order to understand the interaction of several factors. Kasamatsu and Hirai studied a group of Buddhist monks who went on a 72-hour pilgrimage to a holy mountain in Japan. During this time the monks did not eat, drink or speak and were exposed to cold, autumn weather. About 48 hours later they started to have hallucinations, often about their ancestors. The researchers took blood samples from the monks before the ceremony and immediately after the monks reported seeing hallucinations. They found that serotonin levels had increased in their brains. Serotonin activated the hypothalamus and the frontal cortex resulting in hallucinations. They concluded from this study that sensory deprivation triggered the release of serotonin, which actually altered the way the monks experienced the world. The application of such research has improved the lives of many people, because
Tallinn 2012 1. Introduction Aniline (also known as phenylamine or aminobenzene) is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. The largest application of aniline is for the preparation of methylene diphenyl diisocyanate. The majority of aniline serves this market. Other uses include rubber processing chemicals (9%), herbicides (2%), and dyes and pigments (2%). Illustrative of the drugs prepared from aniline is paracetamol. The principal use of aniline in the dye industry is as a precursor to indigo, the blue of blue jeans. Like most volatile amines, it possesses the unpleasant smell of rotten fish. 2.

The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-,
standard. It is the frequency with which a given test correctly identifies a patient as having a disease, or put another way, how closely the mean of test data points accords to the mean of the reference standard. A test with high diagnostic accuracy has relatively few false results in comparison to true results. Precision is the measure of a test result's reproducibility. If repeated testing is performed on an individual patient's sample, the results from each testing should be similar to each other if the test is, in fact, precise. For instance, if a white blood cell count from an individual patient is run 2 to 3 times on a particular hematology analyzer, the results would be considered precise if the results from each testing were in concordance with each other. Results from a hematology analyzer would be expected to be more precise than results from manual differentials.[7] However, it must be confirmed that this is the case, particularly when results
Infectious bovine keratoconjunctivitis Kristjan Rannaäär Veterinary medicine, 2. year, 2. group Abstract Infectious bovine keratoconjunctivitis (IBK) is a highly contagious ocular disease and big problem in cattle farms worldwide. It is the most common ocular disease of cattle caused by bacteria Moraxella bovis. This study focuses on IBK despite having low mortality rate and complete recovery, it causes significant loss of productivity in the herds affected due to the costs of treatment and considerable impact on afflicted animals, including blindness. This research is focused on the details, such as risk factors, pathogenesis, etiology, clinical signs prevention, transmission, and treatment, which animal handlers should be aware of to minimize the harm caused by IBK.

have remained rare and isolated phenomena, since conditions were most likely not yet favorable for a widespread flowering to occur. One day, however, a critical threshold was reached, and suddenly there would have been an explosion of color and scent all over the planet – if a perceiving consciousness had been there to witness it. Much later, those delicate and fragrant beings we call flowers would come to play an essential part in the evolution of consciousness of another species. Humans would increasingly be drawn to and fascinated by them. As the consciousness of human beings developed, flowers were most likely the first thing they came to value that had no utilitarian purpose for them, that is to say, was not linked in some way to survival. They provided inspiration to countless artists, poets, and mystics. Jesus tells us to contemplate the flowers and learn from then how to live
All utility-scale reactors heat water to produce steam, which is then converted into mechanical work for the purpose of generating electricity or propulsion. In 2007, 14% of the world's electricity came from nuclear power. More than 150 nuclear-powered naval vessels have been built, and a few radioisotope rockets have been produced. Nuclear life cycle The Nuclear Fuel Cycle begins when uranium is mined, enriched, and manufactured into nuclear fuel, which is delivered to a nuclear power plant. After usage in the power plant, the spent fuel is delivered to a reprocessing plant or to a final repository for geological disposition. In reprocessing 95% of spent fuel can be recycled to be returned to usage in a power plant. What is nuclear energy? Nuclear energy was first discovered by French physicist Henri Becquerel in 1896, when he found that photographic plates stored in the dark near uranium were blackened like X-ray plates, which
AMBER AND RUSSET - LATE COLOUR CHANGE GENES Copyright 2014, Sarah Hartwell The ancestors of the domestic cat were nondescript black/brown striped tabbies. Over the centuries, mutation produced a wide array of colours based on 2 different pigments. Eumelanin gives the blacks, browns and blues while phaeomelanin gives the reds, fawns and creams. A few other genes give further variations on those colours such silvers, colourpoints and solids/selfs. Mutations continue to occur and unexpected colours also turn up due to inbreeding where recessive genes, hidden for generations, start showing up. AMBER AND LIGHT AMBER During the 1990s, some purebred Norwegian Forest Cats in Sweden produced chocolate/lilac and cinnamon/fawn offspring. However, those colours are not found in the purebred Norwegian Forest Cat gene pool
Her friend, Les, didn't like to use any energy at all. He walked to school, read books instead of watching TV, played the trumpet instead of Guitar Hero, and turned off the lights anytime he left a room. Then one evening, there was a power outage. The lights went out, the TV turned off, and everything became very quiet. Jules became very upset, and quite scared. She couldn't do anything that she wanted to do. She didn't think she could survive. Meanwhile, Les didn't seem to mind at all. He was able to light a few candles and he could still read his books, practice his trumpet, and hang out and play cards with his family. The two friends then realized that there was a big difference in their lifestyles and the amount of energy they used. So Jules decided she should figure out how much energy Les used and then compare her energy consumption to how much she really needed. To do this, they figured out how much energy Jules was using for entertainment, light, heating and
D i ox i n s a n d f u r a n s i n t h e atmosphere. Their impact on humans and nature. Emission sources What are dioxines and furans? The term Dioxin is commonly used to refer to a family of toxic chemicals that all share a similar chemical structure and a common mechanism of toxic action. Most dioxins and furans are not manmade or produced intentionally, but are created when other chemicals or products are made. This family includes: seven of the polychlorinated dibenzo dioxins (PCDDs), ten of the polychlorinated dibenzo furans (PCDFs) and twelve of the polychlorinated biphenyls (PCBs). · PCDD · 2,3,7,8TCDD · PCDF · PCB · PCDDs and PCDFs are not commercial chemical products but are trace level unintentional byproducts of most forms of combustion and several industrial chemical processes.

Decriminalizing Cannabis in Estonia. Estonia is the leading country in Europe with the highest number of drug fatalities per capita, deaths by fentanyl are raising and current drug policy is not doing its job. According to the most recent data, Estonia's overdose mortality rate is seven times the average in the EU. This is a big concern for a country as little as Estonia, and also a reason why the decriminalizing cannabis topic has grown so popular lately. Cannabis, as a soft drug, is criminalized in Estonia and that fact leads people to go after stronger drugs because by the law they are on the same scale. The popularity of “China white” is growing in Estonia, as it is so easily accessible, but

Each part has a special job, and all the parts work together to keep you alive and healthy. Good health is one of the most important things in life. There are certain things we can do to stay healthy. We should eat a balanced diet that includes the right kinds of food and drink plenty of clean, fresh water. We should exercise regularly, strengthening our muscles and keeping us in shape. Exercise helps the blood circulate around our bodies, cleaning out waste and supplying plenty of oxygen
3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. While there are many large-scale renewable energy projects and production, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.Kenya has the world's highest household solar ownership rate with roughly 30,000 small (20100 watt) solar power systems sold per year. Some renewable energy technologies are criticised for being intermittent or unsightly, yet the market is growing for many forms of renewable energy. Climate change concerns coupled with high oil prices, peak oil and increasing government support are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation, and policies
It is noticeable that the eating habits of students in their final year at Freedonian Secondary School are not very healthy. Moreover, there are no students who have both breakfast and school lunch, eat more than four slices of brown bread per day, and avoid fat. In this essay, I will discuss whether prevention is better than trying to treat people who are ill and whether or not this is possible in all cases. I will divide the subject into illnesses caused by lifestyle, and illnesses caused by other factors such as genetic factors. First of all, a person's lifestyle can be a major factor in their wellbeing, both physical and mental. People who eat too much fast, fatty, or sugary foods without doing enough physical activity, may put on weight. This has serious effects and can lead to heart disease. Similarly, people who smoke and drink too much run the risk of getting cancers and heart disease. However, by
determination of the guilt. Furthermore, It has been specifically established in legal precedents in Australia and the U.K. that Munchausen Syndrome By Proxy does not exist as a medico-legal entity. About seven years ago, an attorney asked me how much it would cost to assess a mother accused of MSBP. While reviewing the hours I had spent on previous cases, it struck me that I had confirmed the diagnosis of MSBP in only 2 of the 11 cases that I had evaluated up to that time. Two other cases involved tragic deaths, but I considered the Munchausen label inappropriate for them because one mother was mentally retarded and the other harmed her child while in a delirium. Both went to prison, as did another mother for whom I considered MSBP appropriate. Siin kohal on tähtis see, et kui vanem on vaimselt haige või deliiriumis ja siis teeb oma lapsele haiget, siis ei ole see MSBP.

downward trend since 2004 for used cars and since 2003 for new cars. The decline is notably been high on the 4x4 and SUV segments. That is because of their high fuel consumption. Although in the small car segments the drop has not been so significant. That might be because more people have started to think more about the environment and started to use more public transport or because of the high insurance taxes they are not able or willing to invest so much money for purchasing a car and have started to use bicycles or public transport instead. During the credit crunch people do not have enough finance to make a major outgo like buying a car. Also because the interest rates have decreased on the mortgages and people cannot buy car on credit anymore because their household value has dropped. During the recession there is a good chance to make profit of it, will be for cheaper car brands like skoda, vauxhall and kia
