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

ALCOHOL Alcohol is a widely used substance for both science and in technology. Its name comes from an Arabic word al-kuhl meaning " a powder for painting the eyes". The term was later applied to all compounds that contain alcoholic spirits. 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
1) Behavior can be innate, because it is genetically based. Evolution may play a key role in behavior. 2) Animals may be studied as a means of understanding human behavior. 3) There are biological correlates of behavior. Cognitions, emotions and behaviors are products of the anatomy and physiology of our nervous and endocrine system. Explain how principles of the biological level of analysis may be demonstrated in research. 1) Correlational studies: Study by Buss, who hypothesized that across cultures, men will prefer to marry younger women because of greater reproductive capacity and women will place greater value on a potential mate's earning potential to provide survival advantages. This evolutionary hypothesis was tested in 37 cultures by sending out questioners. 2) Twin studies (type of correlational studies) compare trait similarities in
H. Brown et al. 1998). All Moraxella isolates of veterinary importance, including Moraxella ovis, Moraxella bovis, and Moraxella bovoculi, have the ability to form biofilms. Researches have shown that biofilms are related to the chronicity because of the increased antimicrobial resistance and it is considerable defence mechanism for being washed away or destroyed by bovine tear secretions. One of the main defence factors in the bovine tear is lysozyme. Studies have shown that lysozyme have ability to reduce the production of biofilms, but do not have the capacity to destroy the preformed biofilms (Ely et al., 2017). In addition to the tear film there are other protection factors such as epithelium, phagocytic cells, local secretory antibody. Cornea and conjunctiva epithelial surface are an effective barrier against bacteria invasion. Due to the regeneration of epithelial cells take place every 5-7 days, therefore

Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Air pollution has been a problem throughout history. Even in Ancient Romepeople complained about smoke put into the atmosphere. The effects of air pollution are diverse and numerous. Air pollution can have serious consequences for the health of human beings, and also severely affects natural ecosystems. Because it is located in the atmosphere, air pollution is able to travel easily. As a result, air pollution is a global problem and has been the subject of global cooperation and conflict. Some areas now suffer more than others from air pollution. Cities with large numbers of
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. In this investigation I will study two similar prospective studies on plant based diets and

There are several other variables that impact the soil microflora. For instance, a study by Canbolat et al. (2007) showed that root length, root and shoot weight of plants were decreased by soil compaction, which suggests that microfloral activity in compact soil is lower. Cultural practices The mankind has and will have a major influence on changing the microflora of soils. There are countless activites that have and minor effect, but change the soil composition in the long term as a whole. Although, some activites like agriculture, waste management and forestry carried out to satisfy the needs of the people have major impact on in areas of action. Sidorenko and Buzoleva (2007) stated that soil microbiocenosis is one of the most complicated biological communities. Various interrelationships occur between bacteria in the process of their activity, including those at the metabolic level. These interralationships can
· Reduced access to banking services to save money. · Reduced access to communications technology, such as telephones and the internet. Health care for the homeless Health care for the homeless is a major public health challenge. Homeless people are more likely to suffer injuries and medical problems from their lifestyle on the street, which includes poor nutrition, substance abuse, exposure to the severe elements of weather, and a higher exposure to violence (robberies, beatings, and so on). Yet at the same time, they have little access to public medical services or clinics. This is a particular problem in the US where many people lack health insurance: "Each year, millions of people in the United States experience homelessness and are in desperate need of health care services. Most do not have health insurance of any sort, and none have cash to pay for medical care."

..............................................................................................................13 Introduction What is nuclear power? Nuclear power is any nuclear technology designed to extract usable energy from atomic nuclei via controlled nuclear reactions. The most common method today is through nuclear fission, though other methods include nuclear fusion and radioactive decay. 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
http://et.wikipedia.org/wiki/Katk) 1.1 Symptoms Buboes are commonly found in the armpits, groin or neck. Due to its bite-based form of infection, the bubonic plague is often the first step of a progressive series of illnesses. Two other types are pneumonic and septicemic. However, pneumonic plague, unlike the bubonic or septicemic, induced coughing, and was also very infectious and allowed person-to-person spread. Bubonic plague symptoms appear suddenly, usually 25 days after exposure to the bacteria. (Wikipedia homepage: http://en.wikipedia.org/wiki/Bubonic_plague) Symptoms include: chills; general ill feeling (malaise); high fever (102 degrees Fahrenheit / 39 degrees Celsius); seizures; painful lymph gland swelling called a bubo, commonly found in the groin, but may occur in the armpits or neck, most often at the site of the initial infection (bite or scratch); pain may occur in the area before the swelling appears.

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
14 A normal dose of caffeine is generally considered to be 100 mg, which is roughly the amount 15 found in a cup of coffee. However, more than half of all American adults consume more than 300 16 mg of caffeine every day, which makes it America's most popular drug. Caffeine is generally 17 consumed in coffee, cola, chocolate, and tea, although it is also available over-the-counter as a 18 stimulant. 19 Caffeine is believed to work by blocking adenosine receptors in the brain and other organs. This 20 reduces the ability of adenosine to bind to the receptors, which would slow down cellular 21 activity. The stimulated nerve cells release the hormone epinephrine (adrenaline), which 22 increases heart rate, blood pressure, and blood flow to muscles, decreases blood flow to the skin 23 and organs, and causes the liver to release glucose. Caffeine also increases levels of the 24 neurotransmitter dopamine.
with smaller turbines being used to provide electricity to isolated locations. Utility companies increasingly buy back surplus electricity produced by small domestic turbines. Wind energy as a power source is favoured by many environmentalists as an alternative to fossil fuels, as it is plentiful, renewable, widely distributed, clean, and produces lower greenhouse gas emissions, although the construction of wind farms is not universally welcomed due to their visual impact and other effects on the environment. The intermittency of wind seldom creates problems when using wind power to supply a low proportion of total demand. Where wind is to be used for a moderate fraction of demand, additional costs for compensation of intermittency are considered to be modest.

warming is carbon dioxide (CO2) emissions from fossil fuel combustion, cement production, and land use changes such as deforestation. Its 2013 report states:Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes. Initial causes of temperature changes Greenhouse gases The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in a planet's atmosphere warm its lower atmosphere and surface. It was proposed by Joseph Fourier in 1824, discovered in 1860 by John Tyndall, was first investigated quantitatively by Svante Arrhenius in 1896, and was developed in the 1930s through 1960s by Guy Stewart Callendar. Solar activity Since 1978, output from the Sun has been precisely measured by satellites.
observing a solar eclipse. The image quality was improved with the addition of a convex lens into the aperture in the 16th century and the later addition of a mirror to reflect the image down onto a viewing surface. Giovanni Battista Della Porta in his 1558 book Magiae Naturalis recommended the use of this device as an aid for drawing for artists. First photographs taken with camera obscura were mostly landscapes, the reason for that was a long exposure time. And because landscapes do not move it was a perfect option. They were also used to take family photos or portraits, but it worked a little bit differently than it does nowadays. For example, you had to stay still for a long time for it not to turn out foggy. The camera was also used to capture historical events. Nowadays you can use a camera for everything; you don’t have to wait for it to focus or anything. You just need to press the button and its ready to go. You can
Sheep senses and social cognition Sheep generally are held in low regard as far as cognition and social skills are concerned. However there is now interesting evidence from studies of their behaviour and brain function that they have highly sophisticated social and emotional recognition skills using faces, voices and smell. They are able to recognize and remember many diferent sheep and humans for several years or more and appear to have some capacity for forming mental images of the faces of absent individuals. The precence of such social cognition abilities in this species means that we must pay careful attention to welfare factors such as the composition and

plentiful, sunflower oil is used commonly in the manufacture of soaps and detergents. The use of sunflower oil (and other vegetable oils) as a pesticide carrier, and in the production of agrichemicals, surfactants, adhesives, plastics, fabric softeners, lubricants and coatings has been explored. The utility of these applications is usually contingent upon petrochemical feedstock prices. Sunflower oil contains 93% of the energy of US Number 2 diesel fuel (octane rating of 37), and considerable work has been done to explore the potential of sunflower as an alternate fuel source in diesel engines. Blends of sunflower oil and diesel fuel are expected to have greater potential than the burning of pure vegetable oil. D. Non-Oilseed: The use of sunflower seed for birdfeed or in human diets as a snack, has grown consistently over the past 15 years. Varieties used for non-oilseed purposes are characterized by a larger seed size and require slightly different management practices.
Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world
other countries shows that it is possible now to upgrade biogas with high reliability and at reasonable costs. The Swedish experience shows that biogas can be an economical sustainable fuel with a potential to drastically reduce emissions in urban transport. Other benefits Wastes do not perish. Instead of that, they become more valuable compost. The weeds in animal compost cannot germinate. Biogas has especially positive health effects in rural areas. Smell of animal compost disappears widely after biogas production. Also, disease agents threatening human health coming from animal waste become inactive. Health Biogas can have significant health benefits. According to the Integrated Environmental Impact Analysis carried out by BSP for 600 biogas users and 600 non-users, four percent more non-biogas users have respiratory diseases than those who own biogas plants

General Principles and Unique Individuals: Psychology's main purpose is not to describe the distinctive characteristics of a particular individual. Its main goal is to get at the facts that are general for all of mankind. Psychology hopes to find a route back to understand the individual event. It tries to find explanations to some behaviors and once such explanations are found, they may lead to practical applications; to hel counsel and guide, and perhaps to effect desirable changes. BIOLOGICAL BASES OF BEHAVIOR Any question about bodily movement must inevitably call for some reference to the nervous system, for tu us it is quite clear that the nrevous system is the apparatus which most directly determines and organizes an organisms reactions to the world in which it lives.

plant operators. It was a direct consequence of Cold War isolation and the resulting lack of any safety culture. The accident destroyed the Chernobyl 4 reactor, killing 30 operators and firemen within three months and several further deaths later. Acute radiation syndrome was originally diagnosed in 237 people on-site and involved with the clean-up. Of these, 28 people died as a result of it within a few weeks of the accident. Nobody off-site suffered from acute radiation effects although a large proportion of childhood thyroid cancers diagnosed since the accident is likely to be due to intake of radioactive iodine fallout. Furthermore, large areas of Belarus, Ukraine, Russia and beyond were affected. The Chernobyl site and plant The Chernobyl Power Complex in Ukraine consisted of four nuclear reactors. Two reactors were under construction at the time of the accident. An artificial lake was constructed to provide cooling water for the reactors.
