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-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together. The outer flowers are the ray florets(pähik (õisiku osa) and can be yellow, maroon, orange, or other colors, and are sterile(steriilne, viljatu). The florets inside the circular head are called disc florets. Sunflower head displaying florets in spirals of 34 and 55 around the outside
Estonian University of Life Sciences Report on Soil Microflora By Katrin Vares Tartu 2013 Introduction The purpose of this report is to define soil microflora and establish the importance of it. Since the microorganisms clearly play an important role in preserving the balance of life, the next objective is to look into factors that influence this balance. Natural conditions and cultural impact could be considered as the variables that correlate the most with the activity and composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail.

forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summer temperature is 3-16°C. During the brief summers, the top section of the soil may thaw out allowing plants and microorganisms to grow and reproduce. However, these plants and microorganisms become dormant during the cold winter months. Soil is formed slowly. The constant freezing and thawing in the tundra helps to break the rocks into smaller pieces

Broadleaf trees tend to be nutrient-demanding and their leaves bind the major nutrient bases. The autumn leaf fall provides for an abundant and rich humus which begins to decay rapidly in spring just as the growing season begins. The humus content gives soil horizons a brown colour. Temperate rainforest: This forest has nutrient-rich soil because there is a lot of dead organic matter on the ground. This dead material is being slowly digested by the fungi, insects, and bacteria that live here. Temperate
How can you be exposed to dioxins and furans? You can be exposed to dioxins and furans by eating contaminated food. Dioxins and furans typically stay and build up in the fatty tissues of animals. This means that eating beef, pork, poultry, fish as well as dairy products can be a source of exposure. There are several sources of exposure to dioxins and furans. If you work in or near a municipal solid waste incinerator, copper smelter, cement kiln or coal fired power plant you can be exposed to dioxins and furans. Individuals who burn their household waste or burn wood can be exposed as well. Even forest fires can contribute to the creation of small amounts of dioxins and furans. Dioxins and furans have been found in the air, soil, and food. Dioxins and furans are mainly distributed through the air. However, only a small percentage of exposure is from air. Eating contaminated food is the primary source of exposure.
energy for heating and lighting. Picture 2.5. How energy is used in commercial buildings Electricity and natural gas are the most common energy sources used in commercial buildings. Commercial buildings also use another source that you don't usually find used in residential buildings--district energy. When there are many buildings close together, like on a college campus or in a big city, it is sometimes more efficient to have a central heating and cooling plant that distributes steam, hot water, or chilled water to all of the different buildings. A district system can reduce equipment and maintenance costs, as well as save energy. 9 Picture 2.6. Types of energy used in commercial buildings Retail and service buildings use the most total energy of all the commercial building types. This isn't too surprising when you think of all the stores and service businesses in most towns
Some people are exposed to higher levels of formaldehyde if they live in a new mobile home, as formaldehyde is given off as a gas from the manufactured wood products used in these homes. Formaldehyde is used in many industries. It is used in the production of fertilizer, paper, plywood, and urea-formaldehyde resins. It is present in the air in iron foundries. It is also used in the production of cosmetics and sugar, in well-drilling fluids, in agriculture as a preservative for grains and seed dressings, in the rubber industry in the production of latex, in leather tanning, in wood preservation, and in photographic film production. Formaldehyde is combined with methanol and buffers to make embalming fluid. Formaldehyde is also used in many hospitals and laboratories to preserve tissue specimens.

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
become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
number of reasons. 2.2. Biofuels' feedstock and future projections There are mainly two types of liquid biofuels, which have significantly grown in the last decade: that is bioethanol and biodiesel. Bioethanol is based on sugar, extracted from sugarcane and beet, or starch, which mainly comes from maize, wheat or cassava. Starch- based crops must be first converted into sugars in the saccarification process, which requires substantial volumes of enzymes to turn starch into sugars (Soetaert, W. 2008). The starchy products represent only a small percentage of the total plant mass. Other plants' building blocks like cellulose and lignin are currently not being used to make biofuels as there is not a commercial viable production method for making ethanol form cellulosic biomass (FAO, 2008). Biodiesel is based on the oil crops, such as rapeseed in Europe and soybean in the USA and Brazil

exposure. Smoking also has short term consequences like your breath, clothes, hair, skin, and home smell of tobacco. You do not notice the smell if you smoke, but to non-smokers the smell is obvious and unpleasant. Your sense of taste and smell are dulled. Enjoyment of food may be reduced. Smoking is a serious problem, about 100,000 people in the UK die each year due to smoking. It is very hard to quit smoking but luckily there are things like nicotine patches and gums to help you during the process. But those things won't help you if you lack of two most important things - willpower and determination. 3 Narcotics Narcotics are dangerous and illegal. Narcotics also known as drugs have several forms. You can consume drugs in a shape of a pill, by injecting it with a needle, smoking it and even baking it into a food and then eating it. Let's focus on five drugs marijuana, ecstasy, heroin,
The network of artesian wells provides cattle with water. Natural zones The wet forests also called the rainforests occupy the narrow coastal region in the east. In the west they give place to grasslands with some trees called savannas. Farther west the trees disappear and the savannas give place to the bushlands. The real desert occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees. Plants A rich variety of plant can be found in the natural landscapes of Australia. A lot of species can be found in wet tropical forests in the north and in temperate rainforests in the south. The biggest family of the native plants is the myrties. They include more than 500 species of eucalyptus, or gum trees. Only the big river red gum is seen everywhere. These can be found beside rivers and dry riverbeds. Some gum trees are valuable timber species and have been cut down for many years
The three main kinds of human food are proteins, fats and carbohydrates. We also need certain minerals and vitamins. A balanced diet one that includes all those things is necessary for good health. You may have a favorite food, but the best choice is to eat a variety. If you eat different foods, you're more likely to get the nutrients your body needs. Taste new foods and old ones you haven't tried for a while. Some foods, such as green veggies, are more pleasing the older you get. Shoot for at least five servings of fruits and vegetables a day -- two fruits and three vegetables. Drink water and milk most often. When you're really thirsty, cold water is the No. 1 thirst-quencher. And there's a reason your school cafeteria offers free milk. You need calcium to grow strong bones, and milk is a great source of this mineral. How much do you need? Aim for 3 cups of milk per day, or its equivalent. You can mix it up by having milk and some other calcium-rich dairy foods.
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 smoker inhales only some of the smoke from a cigarette and not all of each puff is absorbed in the lungs, a smoker gets about 1 to 2 milligrams of the drug from each cigarette. A drop of
US$36.1 billion. Fuel exploration and production dominate this sector, but the processing of other types of mineral resources has grown significantly. In 1996, the top non-fuel minerals were gold with production of US$2.05 billion, copper US$1.47 billion, nickel US$1.45 billion, and zinc US$1.25 billion. There was also significant production of lead and iron. There are about 50 major gold mines in Canada and the country leads the world in technologies which extract gold from rock and soil. The nation is the world's largest producer of zinc and the fifth largest producer of lead. Among the provinces, Ontario is the top producer of non-fuel mineral resources, followed by Quebec, British Columbia, Saskatchewan, and Newfoundland. Each year Canadian companies spend over US$600 million to find or develop new mines and fuel supplies. However, environmental concerns and increased regulation have led many Canadian mining companies to shift exploration elsewhere
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.
of these can vary considerably. Some technologies are already mature and economically competitive (e.g. geothermal and hydropower), others need additional development to become competitive without subsidies. This can be helped by improvements to sub-components, such as electric generators. The table shows an overview of costs of various renewable energy technologies. For comparison with the prices in the table, electricity production from a conventional coal-fired plant costs about 4¢/kWh. Though in some G8 nations the cost can be significantly higher at 7.88p (~15¢/kWh).Achieving further cost reductions as indicated in the table below requires further technology development, market deployment, an increase in production capacities to mass production levels,and of the establishment of an emissions trading scheme and/or carbon tax which would attribute a cost to each unit of carbon emitted; thus reflecting the true cost of energy
helped a lot in the field of communication. The first models of cameras were used in the years before Christ where they were used to see closely objects. After its emergence was marked a before and after in history because thanks to this artefact can capture exact moments in which a event happened. Advancing in history have improved the types of cameras, passing cameras that took several minutes to take a photograph so far in which the process of taking a photograph or several is instantaneous. In addition, the cameras allow us to keep a record of a large number of important events, either of oneself or of important moments for the global history. As the saying goes, "a picture is worth a thousand words" 4 Uses of the Photographic Camera (SEBA) Camera obscura, the first camera was first mentioned by Chinese philosopher Mo-Ti in the 5th century before Christ. He formally recorded the creation of an

The biggest family of native plants is the myrtles. They include more than 500 species of eucalyptus, or gum trees. Only the big river red gum is seen nearly everywhere. These can be found beside rivers and dry riverbeds. Some gum trees are valuable timber species and have been cut down for many years. Gum tree leaves are full of oils, which evaporate easily. Another big family of native plants is the acacias. They are also known as wattles. There are about 900 wattle species. The golden wattle is Australia’s native flower. Its gold flowers and green leaves inspired the colours worn by many Australian sporting teams. In Australia bushfires are very often to happen. Because the trees and shrubs do not lose their leaves in winter, but grow throughout the year. But when the dry leaves and branches
as all costs ultimately will make way to the final market place to be reflected in the price paid by the end user. Therefore, the leading edge companies seek to make the supply chain as a hole more competitive through the value it adds and the cost it reduces overall. Thus today the real competition is not the companies against the companies but rather supply chain against supply chain. DEFINITIONS Supply Chain Management (SCM) is the process of planning, implementing, and controlling the operations of the supply chain with the purpose to satisfy customer requirements as efficiently as possible. Supply chain management spans all movement and storage of raw materials, work-in-process inventory, and finished goods from point-of-origin to point-of-consumption. According to the Council of Supply Chain Management Professionals (CSCMP),
Because sea passages were narrower between the Java and Borneo islands, the first Aborigines could reach Australia from the north. When they finally got to Australia, it was in a much better condition than nowadays. There were large animals, who are now extinct, that provided much meat. The Aborigines lived in harmony with the environment. Because they were cut off from the rest of the world, Aborigines could not trade goods, acquire animals or crop seed, which was very important because the land did not contain any cultivated crops. Aborigines lived in clans that all had occupied a piece of land. Nobody thought about selling, buying or trading land because the clan was a part of the land they owned. Finding food was not easy at that time. In some areas, both men and women had to spend over half 2 of each day on hunting or gathering food
The more interesting portion of the story started well after Trent Reznor left the stage. Roughly 72 hours later, I tested my bodyfat percentage with an ultrasound analyzer designed by a physicist out of Lawrence Livermore National Laboratory. Charting the progress on my latest experiment, I'd dropped from 11.9% to 10.2% bodyfat, a 14% reduction of the total fat on my body, in 14 days. How? Timed doses of garlic, sugar cane, and tea extracts, among other things. The process wasn't punishing. It wasn't hard. Tiny changes were all it took. Tiny changes that, while small in isolation, produced enormous changes when used in combination. Want to extend the fat-burning half-life of ca eine? Naringenin, a useful little molecule in grapefruit juice, does just the trick. Need to increase insulin sensitivity before bingeing once per week? Just add some cinnamon to your pastries on Saturday morning, and you can get the job done.

of words, sometimes resulting in changes to the words in question. (Examples: rosemary, cutlet, crayfish, island, nickname, newt, cherry, pea) For example, one frequently repeated “folk etymology” is that the expression rule of thumb derives from a medieval law that restricted wife beaters to a stick no bigger round than the thickness of their thumbs. It makes for a sensational story, but has no truth in it. Professional etymologists use the term folk etymology to describe the process by which an unfamiliar word is altered through use to resemble a more familiar word. Folk etymologies result from mishearing, mispronunciation, misunderstanding, and a desire to rationalize words that make no sense to the speaker. Here are a few examples of words that have been altered by the process of folk etymology: shamefaced: OE scamfaest, “restrained by shame.” The element “fast” had the sense it has in this sentence: The prisoner was made fast by chains

Non-verbal communication Nonverbal communication is usually understood as the process of communication through sending and receiving wordless messages. Such messages can be communicated through gesture; body language or posture; facial expression and eye contact; object communication such as clothing, hairstyles or even architecture; symbols and infographics. Speech may also contain nonverbal elements known as paralanguage, including voice quality, emotion and speaking style, as well as prosodic features such as rhythm, intonation and stress.
large sections, also called books (Book 1, Book 2, Book 3, etc.). A lover of books is usually referred to as a bibliophile, or, more informally, a bookworm. A store where books are bought and sold is a bookstore or bookshop. Books can also be borrowed from libraries. In 2010, Google estimated that there were approximately 130 million unique books in the world. Etymology The word book comes from Old English "bc" which itself comes from the Germanic root "*bk-", cognate to beech. Similarly, in Slavic languages (e.g. Russian, Bulgarian and Macedonian) "" (bukva--"letter") is cognate to "beech". It is thus conjectured that the earliest Indo-European writings may have been carved on beech wood. Similarly, the Latin word codex, meaning a book in the modern sense (bound and with separate leaves), originally meant "block of wood". History of books Antiquity
Many of the bigger species, such as the Grey Wolf and the Brown Bear were hunted to extinction many centuries ago. However, recently, many of these large mammals have been reintroduced to some areas of mainland Britain. The largest mammals that remain in Britain today are members of the Deer family (for example: the Red Deer) Plants The mild climate, ample rain and long growing season support a great variety of plants, which grow exceptionally well. Sometimes plant growth is compared to the lush areas of the well-watered and mild coasts of the states of Washington and Oregon. Most of Britain was once covered with thick deciduous forests in which oak trees predominated. The impact of centuries of dense human population has massively altered the flora of Britain and only tiny remains of these forests remain today. Although 10 per cent of Britain is still forested, most of this area consists of
much to educators. Since I don't have an educational theory neatly worked-out, nor an outline of my perceptions, my intent is to address each educational ingredient that comes to my mind. After I've said what I think about each topic, readers may have a fair comprehension of my philosophy. First comes sensitivity. If a person be insensitive, be it from numbing cold, exhaustion, drugs, genetic makeup, or upbringing, then the process of education is bogged down, and results come only after great efforts. Sensitivity in my integrated meaning is broad, covering literally the senses, so that deaf and blind people are less sensitive, as well as people whose senses work perfectly, but whose receptivity or thought processes are blunted for whatever reason. A person can be insensitive in one way, such as blind, and extraordinarily sensitive in another way, such as in hearing
Thus the following questions drive the present research in its goal of gaining a better understanding of these new business models: 1. What are the main problems connected with the construction industry and what are their causes? 2. Which problems have been arising in the Estonian construction industry? 3.
