Soil microflora

nutrients, pH, and many other factors which may vary between locations but also within a single plot and over very small distances (OECD, 2007). Nevertheless of the quantity of microflora, biomass of all microorganisms living in soil play an important role in the functioning of entire soil ecosystems because their enormous biochemical activity (Barabasz et al. 2002). Soil microflora cycles carbon, nitrogen, phosphorus, and sulfur, plays a role in soil structure formation, decomposition of organic matter, toxin removal, promoting plant growth, and in changes in vegetation (Canbolat at al. 2005 and Martin et al. 2012). Therefore, soil microflora plays a major role in preservation and the balance of life. Because of active role of soil micro- population, the diminution in microbial activity is always alarming (Barabasz et al. 2002). Factors influencing soil microflora Soil microorganisms depend on soil for their nutrition, growth and activity. Based on My

Maakera koostis

Käesoleval ajal kaevandatakse põlevkivi Eestis, Venemaal, Hiinas, Austraalias ja Saksamaal. Eesti maardlas on põlevkivi kaevandamise tingimused võrreldes teiste leiukohtadega lihtsad - väike sügavus, rõhtne lasuvus, kihindi püsiv paksus. Teadlaste arvates on Eesti põlevkivi ehk kukersiidi tekkimisel olnud lähteaineks sinivetikad (tsüanobakterid). Huumus Humiinained Huumus Nonliving, finely divided organic matter in soil, derived from microbial decomposition of plant and animal substances. Humus, which ranges in colour from brown to black, consists of about 60 percent carbon, 6 percent nitrogen, and smaller amounts of phosphorus and sulfur. As humus decomposes, its components are changed into forms usable by plants. Humus is classified into mor, mull, or moder formations according to the degree of its incorporation into the mineral soil, the types

Art Nouveau, ornamental style of art that flourished between about 1890 and 1920 throughout Europe and the United States. Art Nouveau was aimed at modernizing design Artists drew inspiration from both organic and geometric forms, evolving elegant designs that united flowing, natural forms resembling the stems and blossoms of plants Art Nouveau is characterized by its use of a long, sinuous, organic line and was employed most often in architecture, interior design, jewelry and glass design, posters, and illustration There were used alot of muted greens, browns, yellows, and blues.

IT alase uudise kommenteerimine

Jälgisin küllaltki kaua erinevaid portaale, et leida endajaoks sobiv uudis, mida kommenteerida. Lõpuks jäin pidama uudisel, mis räägib inimesesugustest robotitest, mida tahetakse hakata kasutama eriolukordades. Nende robotite eesmärgiks, nagu öeldud, on eriolukordades inimeste aitamine. See tähendab seda, et kui mõnda linna tabab mõni suur torm või muu inimeste elu ohtu seadev tegur, siis saadetakse välja robotid, mis meenutavad inimesi, kuid kellel on mitmeid eeliseid pärisinimeste ees, näiteks on nad ülitugevad ja neid ei kahjusta kemikaalid, mis võivad näiteks keemiarelva kasutuse või tuumajaama kahjustada saamise korral õhus hõljuda. Need robotid peavad saama hakkama paljude ülesannetega, millega inimesed ei suudaks, näiteks puude tõstmine jms; samas ka ülesannetega, mida täidavad tavaliselt inimesed, näiteks tuletõrjeauto juhtimine. Need robotid on alles ehitusjärgus ning organisatsioon, mis neid ehitab, on kuulutanud välja võist...

Thoughts on Air Pollution Essay

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

In most cases, such problems represent no organic disease or serious behavior disorder but nevertheless can cause more serious complications in toilet training than parents recognize. CLINICAL TRIALS Clinical experience, however, suggests that in most children these problems can be managed successfully within the realm of general pediatric practice.

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

✔ It helps the farmer to easily supervise and monitor the land and protect his livestock from being hurt or hounded by dangerous wild animals. ✔ With the introduction of intensive farming, farm produce, such as vegetables, fruits, and poultry products have become less expensive. It also aids in solving the worldwide hunger problems to a great extent. This means that common people can now afford a balanced and nutritious diet. ✔ Many opine that organic food can be afforded only by the elite strata of the society. Apart from that, large farming spaces are required to cultivate organic crops using natural manure. However, with the introduction of intensive farming, the space, equipment, and other requirements for farming are less and more economical. ✔ The EPA (Environment Protection Agency) has set certain rules and regulations on how livestock, pesticides, and animal manure are to be maintained.

Fosfor- ja lämmastikväetised

Jõhvi Gümnaasium Fosfor- ja lämmastikväetised Referaat Koostaja:Maila Meldre Klass:10A Juhendaja: Kristelle Kaarmaa Jõhvi 2009 Lämmastikväetised Lämmastikväetised on vees hästi lahustuvad. Lämmastik on meie mineraalmuldades esimene miinimumis olev toitelement ja tema mõju saagikusele seetõttu kõige suurem. Lämmastikuga üleväetamine pikendab aga taime kasvuperioodi, põhjustab teraviljade lamandumist, saagi nitraatidesisalduse suurenemist, keskkonna reostust . Mineraalväetiste lämmastik kas on nitraatne või muutub mullas mõne tunni kuni mõne päeva jooksul nitraatideks. Taimed kasutavad nitraate valkude jt ühendite sünteesil. Nitrifitseerivate bakterite toimel muutuvad aja jooksul ka mulda viidud ammooniumiühendid taimedele omastatavateks nitraatideks. Kuna muld ei seo nitraat...

OLED kuvar, kolmas kontrolltöö, Arvutid I

OLED (Organic Light-Emitting Diodes) kuvar Üldist Orgaaniliste valgusdioodidega kuvarites kasutatakse enamasti klaasalust, kuid neid võib teha ka plastmassist või mõnest muust painduvast materjalist aluskilele nagu on tehtud firma Universal Display poolt välja töötatud Flexible OLED (FOLED) puhul. Ennustatakse, et seda liiki kuvariekraanid leiavad lähemas tulevikus laialdast kasutust mobiiltelefonide, pihuarvutite, digikaamerate jt. käsiseadmete juures. Esialgu on OLED-ekraanide puuduseks suhteliselt lühike tööiga (ca 1000 tundi), kuid juba lähemal ajal loodetakse saavutada 10000 tunni piir ja võimalikuks peetakse kuni 90000-tunnise tööea saavutamist. Tööpõhimõte ja ehitus OLED koosneb elektrit juhtivast orgaanilise materjali kihist, mis paikneb kahe elektroodi (anood ja katood) vahel. Neid materjale nimetatakse orgaanilisteks pooljuhtideks, sest omavad juhtivustasemeid isolaatorist juhini. Enamus tänapäevased OLED-id on kahekihilised...

"Northern Europe’s seas. Norther Europe’s environment"

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.

How to produce bioenergy from agricultural resources without harming the environment

(including chopped area) is 1300 ha •Of that appr. 500 ha was mowed and balled last year •The first phase is restoring the flooded meadow •As for now the material is chopped and just left on the meadow •Dry matter – 85,86 – 90.33 In the DM: •Raw protein 6,19 – 10,04 % •Raw ash 3,50 – 5,95 % •Raw fiber 28,89 – 33,25 % •Metabolizing energy when feeded to cows: 8,2 – 9,0 MJ/kg Perspectives • Bioenergetics – Hay as an organic fuel (burning) – Biogas production • Hay for making compost Problems Benefits • Extensive management, nature friendly • Helps to preserve valuable area • Low cost? Disadvantages • Mowing time – not before 10-th of July • Transportation – on the meadows and to the plant • Floods and other weather conditions can be unpredictable Balanced ethics as basic principle of sustainable society • Sustainable agriculture as implementing

PETROLEUM

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

This wildflower will adapt to lawns, especially if they are not mowed too often during the spring or cut too low. HABITAT & RANGE The native Common Blue Violet occurs in every county in

Monitorid

Monitorid Arvutikuvar ehk arvuti monitor on arvuti väljundseade, mis muudab analoog- või digitaalinfo pildiks. Algselt kasutati monitorideks 20. sajandil sarnast tehnoloogiat, mis ka telekate puhul, kus peakomponediks oli kineskoopkuvar. Erinevaid monitori suurusi on väga palju. Resolutsioonide suhtes pakutakse üldiselt 1280 x 1024 kuni 3840 x 2160 pikslit. Üldlevinud on FULL HD ehk 1920 x 1080, mis tähistab pikslite arvu monitoril. Iga piksel on võimeline näitama erinevat värvi. Pidevalt arenevas ühiskonnas muutub ka pikslite arv monitoril aina suuremaks, sest mida suurem arv piksleid - seda teravam ja tõetruum pilt. Samuti oluliseks aspektiks on ekraani kaadrisagedus (Hz) ehk võime kuvada vastav arv pilte ehk kaadreid sekundis. Harilikult on monitorid 60 hertsised, kuid mida rohkem, seda parem! Suurem arv kaadreid sekundis tagab sujuvama ning reaalsemana tunduva pildi. Filmide vaatajad ning mä...

Gustav Adolfi Gümnaasiumi gümnaasiumi õpilaste teadlikkus meigitoodete koostisest ja mõjust nahale

(Wohrle, 2013) 1.3.4 Aroomid Kosmeetikatoodetes kasutatakse tihti aroome, need võivad sisaldada kuni 4000 erinevat koostisosa. Tavaliselt jääb see arv siiski 50-100 peale. Nendel koostisainetel puuduvad piirangud ja ei ole nõutud toodetel eraldi välja tuua. Aroome kasutatakse, et muuta toote lõhn tarbijale kutsuvamaks ja on lisatud enamustele turul olevatele kosmeetikatoodetele. Nendes olevatest kemikaalidest 95% on sünteetilised naftasaadused. (Green organic world) Aroomide kasutamine võib mõjutada kesknärvisüsteemi, segada ainevahetust, hormoone, ja tegutseb, kui endokriinnäärme kahjustaja. See koostisaine võib põhjustada peavalu, pööritust, hingeldamist, allergiat, oksendamist, depressiooni ja hüperaktiivsust. (Green organic world) 1.3.5 Mineraalõlid (kütused) Mineraalõlid ja nafta on laialdaselt kasutatavad ained kosmeetikas ja on päritolult samad fossiilkütused

Agriculture

and soft fruits, and bulbs and flowers. The high productivity of the arable sector has been achieved by the removal of hedgerows to create larger fields, by mechanization, and by the intensive use of fertilizers, pesticides, and fungicides. As with the issue of animal treatment, these trends in arable agriculture have provoked public concern. Combined, these concerns have helped encourage the rapid growth of vegetarianism in Britain since the early 1980s and the expansion of organic farming, although this is still on a very small scale. However, partly in reaction to these concerns, and partly because of costs, the trend is now towards lower chemical use in farming. Agricultural policy includes schemes to encourage farmers to take land out of agricultural production to adopt more environmentally kind, but less productive methods of farming to impose production quotas on certain products, like milk, and to reduce subsidies on others.

Natural resources - our treasure

Natural resources-our treasure Natural resources are land or raw materials like minerals, fluids, gases, organic matters and also woods, groundwater, animals and so on, in other words it's everything that human hasn't created. These resources are also used in industry. We get natural resources from the environment. Many of them are essential for our survival while others are used for satisfying our wants. Renewable resources: Some natural resources can be reproduced within a few years or decades. These are called renewable resources

My company: The Greenery

The company’s headquarters is located in Tallinn. The drive-in restaurants are located in major cities of Estonia. There are five drive-in restaurants in Tallinn, two in Tartu and one in Pärnu, Narva and Saaremaa. In the near future we are planning to expand into Nordic countries. The Greenery does not have many competitors, because the most fast food restaurants do not offer many healthy food alternatives. What differentiates us in the marketplace is that we focus on procuring organic and local food and each guest can easily customize the meal to their specific taste and diet requirements. The menu will offer seven categories of fast, simple, nutritious, and delicious dishes. The categories are: wraps, burritos, salads, rice, pasta, soups, smoothies, and frozen yogurt. A customer can choose to order a "Chef-Designed" option from one of these categories, or can elect to "Build Your Own" customized dish that is specific to their individual taste and dietary requirements

Manual For Bio-fuels

The calorific value is the amount of heat generated by a given fuel mass when it is completely burned and it is measured with a socalled bomb calorimeter. The higher or gross calorific value and lower or net calorific value (qgr and qnet ,respectively) can be found via the calorific value measured in the bomb calorimeter. Wood fuels Final products from wood How pellets are made http://www.youtube.com/watch?v=B4VP129rWcY Peat properties Peat is an organic deposit formed from the accumulation of decomposed remains of plants in the oxygenpoor environment of excess water. Peat consists mainly of partially decomposed remains of plants and humus. The most essential indices of peat are decomposition degree, moisture content, mineral (ash) content, density and calorific value. Although peat is of biological origin, it is not considered a renewable biofuel usually, but a slowly renewable fuel of biological origin.
