Iseseisev töö nr. 1 1. Synthesis of Bioactive Compounds. Bioaktiivsete ainete süntees. Teema käsitleb võimalusi, kuidas saaks laboratoorselt bioaktiivseid aineid toota. Kõnealuseid aineid on inimene juba pikki sajandeid ise läbi kogemuse teatud toitudega manustanud. Tänapäeval me aga teame, mis tegelikkuses neis toiduainetes meie ainevahetusele ja immuunsussüsteemile kaasa aitavad ning seega tasub neid ka omal käel sünteesida, kuna vajalikke toiduaineid ei pruugi alati käeulatuses olla. Seega ongi töö eesmärgiks laiendada

Summary The present summary is based on the book "Northern Europe’s seas. Norther Europe’s environment" by Britt Aniansson. Oceans and seas are polluted every day by different substances that reach the waters from different sources on land and at the sea. The author points out four main problems in the marine environment. One of the main problems is the chemical pollution which is caused by natural or man- made halogenated compounds, pesticides, dioxins, chlorinated organic materieals and so on. These compounds are causing deformage in marine animals and are storaged in their fatty tissues. They have also been found in organisms throughout the world oceans because they are dispersed quickly by winds and currents. Another problem that affects the marine life is excess phosphorus and nitrogen flow into the sea from towns, factories and other man-made sources which cause intense algae growth.

Solar power is energy that comes from the sun. The sunlight gives off energy as heat. Solar power is a renewable source of energy. How does solar power work? Solar panels are used to collect sunlight. Solar panels are made up of photovoltaic cells that convert the sunlight into energy. Why do we need it? How does it lead to better health? Solar power is source of clean energy. It does not produce pollution or greenhouse gases or carbon compounds. Solar power would be a lot safer for the environment and a lot better for the health of people. What would happen if we don't use solar power? If we don't start using solar power, we would use oil and coal. They produce pollution and will cause millions of people to suffer from respiratory related problems. The oil and coal will run out and people will have to resort to other ways of power. Solar energy Karol Pakkas

Some areas now suffer more than others from air pollution. Cities with large numbers of automobiles or those that use great quantities of coal often suffer most severely from problems of air pollution. CAUSES There are many different chemical substances that contribute to air pollution. These chemicals come from a variety of sources. Among the many types of air pollutants are nitrogen oxides, carbon monoxides, and organic compounds that can evaporate and enter the atmosphere. Air pollutants have sources that are both natural and human. Now, humans contribute substantially more to the air pollution problem. Forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity are all among the natural causes of air pollution. Usually, natural air pollution does not occur in abundance in particular locations. The pollution is
The levels of dangerous waste continue to grow thanks to individuals too. Some people are too lazy to throw the trash into the litter bin. They think that it is easier to dump it without realizing that it could be dangerous for the environment. As a solution, the government can increase regulations on the disposal of hazardous waste. It can create modern landfills that are using modern technologies. Those landfills could break down chemical compounds into less dangerous forms. Civilians can choose not to buy those products which require the production of hazardous waste. They can choose products with biodegradable packages. They can organize collective actions for cleaning the waste from the nature. Hazardous waste is a big problem to humans and nature. We have to pay more attention to this problem, because waste poisons the earth and consequently our food too.

debris in the Baltic Sea aswell. This is how the museum looks like from the outside. Here are our students in front of the Ristna Sea Store sign. The most common components of marine debris in the Baltic Sea are food waste and packages. 31-43% of marine debris are plastic bottles and even 50-63% of marine debris is plastic. Marine debris is harmful for everyone. It causes garbage ingestion and entanglement for marine animals. For marine life it causes accumulation and spread of toxic compounds and garbage deposition. These pictures are illustrative. Ristna Sea Store is organized into different departments and that's why it's called Store. From that exhibition you can find differend findings and their decomposition times in nature. This is how the exhibition looks inside. On this map they have tagged all the countrys where all these findings have came from to the coast of Hiiumaa. -- Departments... All this garbage decomposes for a really long time
Air pollution in Japan Birgit Tohter Air pollution The presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk. The effects of air pollution is global warming, heart problems, acid rains etc. There are solutions like public transport, cleaning smokestacks, laws, renewable sources, The history Industrial activity in Japan devoloped rapidly after the World War II. People became really sick and described it as more horrible suffering than death. In the 1970s Japan managed to clean up

environment and on human health, in particular on the most vulnerable groups like children. Human health effects include impairment of the immune system, the nervous system, the hormonal system and the reproductive functions. Dioxins are also suspected of causing cancer. How Are We Exposed to Dioxins? Although formation of dioxins is local, environmental distribution is global. Dioxins are found throughout the world in the environment. The highest levels of these compounds are found in some soils, sediments and food, especially dairy products, meat, fish and shellfish. Very low levels are found in plants, water and air. Most of us receive almost all of our dioxin exposure from the food we eat: specifically from the animal fats associated with eating beef, pork, poultry, fish, milk, dairy products. How can you be exposed to dioxins and furans? You can be exposed to dioxins and furans by eating contaminated food. Dioxins and furans
grown from 45 million tons to 175 million tons and this only by 10 years. Its condition is a challenge for the nine coastal states and their populations - there are 90 million people living in this catchment area. [1] The sources of marine pollution are municipal and industrial waste inputs directly into the sea or rivers, and atmospheric inputs mainly from traffic and farming. Originating from cellulose producing and from paper mills, large amounts of poisonous chlorinated compounds are polluting the coastal waters of Sweden and Finland. Most of this material is still present in sediments of the central Baltic Sea and can be terminated by near bottom currents. [2] Unsustainable factory farming made the Baltic Sea one of the world's most polluted seas.

Conversion Or zero-derivation! Conversion – a type of derivation where no suffix is used to change the word class. A linguistic process that assigns an already existing word to a new word class (part of speech) or syntactic category. This process is also known as a functional shift or zero derivation.
Acid rains Stefani Nimtsuk What is acid rain? Rain or any other form of precipitation that is unusually acidic It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids History Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England Though acidic rain was discovered in 1852, it was not until the late 1960s that

Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid
Purists of the languages are resisting the arrival of English in their vocabulary. The standard English oh today is known as BBC English. Few British people know much about grammar, since it is not usually taught in schools. Spelling and pronunciation seem to be the most difficult aspects of the English language for foreign students. English is very rich in synonyms. The huge vocabulary is due to the free admission of words from other languages and the easy creation of compounds and derivaties. English vocabulary numbers at least 750,000 words. Educated English speakers use approximately 5,000 words in speech and up to 10,000 in written communication. Shakespeare used a vocabulary of 33,000 words. Old English, had several inflections to show singular and plural, tense, person, but over the centuries words have been simplified. Adjectives do not change according to the noun and gender is not a problem in English. The loss of
6 According to the absolute mobility, taken from the tables, both of these substances seem inseparable because they migrate equally. However, both these substances have different pKa values, i.e mobility is dependent on pH. Electroosmotic flow (EOF) Migration of substances depends on the one hand, on specific for compounds parameters as charge and size, and on the other hand, it is affected by factors such as pH and ionic strength of the working buffer, the field strength and temperature. Migration is complicated by electroosmotic flow which is caused by charges on the inner surface of the capillary. EOF is a feature of a capillary electrophoresis and is not observed in conventional electrophoresis in a
There are several steps that can be taken to help prevent water pollution from getting worse. Keep Machinery in Good Working Order The oil used to lubricate engines in all types of machines needs to be changed regularly. When the oil is changed, it presents a number of environmental hazards if not disposed of properly. As oil moves throughout the crank case of an engine, it breaks down into many different types of carcinogenic and even mutagenic compounds. When a leaky engine releases this oil into the street, it runs to the sewer and from there it becomes part of a laundry-list of contaminants that makes its way into waterways. Even a small drip of oil can turn into a disaster when you consider the fact that there are more than 250 million cars on the road in the United States alone. Even if all of these vehicles were in perfect working order, the disposal of the used oil would still be a huge issue. Clean Up Beaches and Waterways

Other affected areas include the southeastern coast of China and Taiwan Causes · It is caused when sulfur dioxide and nitrogen oxides are released into the air. In the atmosphere they react with water, oxygen and other chemicals to form more acidic pollutants, known as acid rain. Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by wind. As a result, the two compounds travel long distances where they become part of the rain, sleet, snow or fog. SO2 and NOx come mainly from power stations and factories burning fossil fuels, or from motor vehicles. · Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H 2CO3 CO2 + H2O H2CO3 · During the last century the rain water in some parts of the world has become far more acidic.

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of
is a rough correlation between the frequency of a word and its length; this is known as Zipf's Law (see Crystal 1987). In languages with widespread literacy, other means of forming new words are based on the writing system. In English both abbreviations (e.g. BBC, MP, PC, etc.) and acronyms (e.g. radar) are common. (Radar stands for RAdio Detection And Ranging.) Other languages use other devices (for example, in languages that use the Chinese writing system, it is common for long compounds to be reduced to the first elements of the subcompounds they contain, so that Japanese too-kyo dai-gakku `Tokyo University', literally `east-capital big-school' is usually referred to as too-dai literally `east-big' but more idiomatically translated as something like `TU'). German abbreviations/acronyms are often based not on the first letter of the component words, but on the letters for the onset and nucleus of the first syllable of the component words, e.g
Humic acid has the average chemical formula C187H186O89N9S1 and is insoluble in strong acid (pH = 1). One of two classes of natural acidic organic polymer that can be extracted from humus found in soil, sediment, or aquatic environments. The process by which humic acid forms in humus is not well understood, but the consensus is that it accumulates gradually as a residue from the metabolism of microorganisms. Transition and heavy metals--for example, Fe3+ or Pb2+--as well as other compounds having aromatic or hydrophobic (water-insoluble) chemical structures (i.e., organic pesticides or anthropogenic hydrocarbons), react strongly with humic acid. This property makes it an effective agent in sequestering many of the pollutants in terrestrial and aquatic environments. Fulvohape Väiksema molekulmassiga kui humiinhape. This organic matter is soluble in strong acid (pH = 1) and has the average chemical formula C135H182O95N5S2.
(especially of vanadium), give aniline black. Hydrochloric acid and potassium chlorate give chloranil. Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black. Hypochlorous acid gives 4-aminophenol and para-amino diphenylamine. Oxidation with persulfate affords a variety of polyanilines compounds. These polymers exhibit rich redox and acid-base properties. 5. Toxicity data on chemical a) General toxicity · Acute toxicity after single administration The average lethal inhalation dose for humans is reported to be 25 mg/l air or 0.35- 1.43 g/kg bodyweight. With respect to methaemoglobin formation the no-effect dose of aniline in adult human is about 0.2 mg/kg bodyweight. In animal experiments the
(parts of) microorganisms, or of cells and tissues of higher organisms, so that these supply goods and services of use to the food industry and its consumers.[2] Biotechnology combines disciplines like genetics, molecular biology, biochemistry, embryology and cell biology, which are in turn linked to practical disciplines like chemical engineering, information technology, and biorobotics. Patho-biotechnology describes the exploitation of pathogens or pathogen derived compounds for beneficial effect. Information technology -Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.
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

microbial attack that has been observed in numerous pathosystems. · In plant-pathogen interaction, an earlier study showed that the t-SNARE is necessary for endocytosis during the initial stage of development of plant-pathogenic corn smut fungus Ustilago maydis, underlying the importance of SNAREs for both partners of plant-microbe interaction. · In spite of the well understood role of secreted antimicrobial compounds and polypeptides at the cell boundary, the transport route from site of synthesis to the site of action is still a mystery. SNAREs are supposed to have a fundamental role in plant defense (Collins et al., 2003). Inactivation of allele AtSYP121 (encodes Qa- SNARE) and its ortholog HvROR2 in barley have high levels of host cell entry either by non-adapted fungal species or in the highly resistant barley mlo mutant allele (Assaad et al., 2004).
