Education

Faculty and students should together study the wells, mines, farms, feedlots, and forests that supply the campus as well as the dumps where you send your waste. Collectively, begin a process of finding ways to shift the buying power of this institution to support better alternatives that do less environmental damage, lower carbon dioxide emissions, reduce use of toxic substances, promote energy efficiency and the use of solar energy, help to build a sustainable regional economy, cut long- term costs, and provide an example to other institutions. The results of these studies should be woven into the curriculum as interdisplinary courses, seminars, lectures, and research. No student should graduate without understanding how to analyze resource flows and without the opportunity to participate in the creation of real solutions to real problems....

Dioksiinid ja dioksiinitaolised ühendid

Tallinna Ülikool Dioksiinid ja dioksiinitaolised ühendid Mihkel Tibar B-2 2007 Sissejuhatus Dioksiinideks peaks õigupoolest nimetama ainult kahte heterotsüklilist C 4H4O2 isomeeri (joonis 1), kuid lihtsuse mõttes kasutatakse seda nimetust ka keerulisemate ühendite puhul. Dioksiinidest kui saaste- ja mürkainetest rääkides mõeldakse nende all enamasti polükloreeritud dibenso-para-dioksiine (PCDD, joonis 2), kuid tihti koondatakse selle nime alla ka polükloreeritud dibensofuraanid (PCDF), millel on sarnane struktuur ja keemilised omadused (joonis 3). PCDD-d on väidetavalt kõige mürgisemad ühendid üldse, mida inimene tekitada suudab ja seejuures õnnetuseks ka väga püsivad. Dioksiine ega furaane pole kunagi tööstuslikult toodetud, nad tekivad kõrvalproduktidena erinevates tööstuslikes protsessides. Polükloreeritud dibenso-p-dioksiinide (PCDD) ja dibensofuraanide...

Keskkonnaprobleemid

The animals and plants most at risk are those that could come into contact with a contaminated sea surface. Marine mammals and reptiles; birds that feed by diving or form flocks on the sea; marine life on shorelines; and animals and plants in mariculture facilities. The most toxic components in oil tend to be those lost rapidly through evaporation when oil is spilt. Because of this, lethal concentrations of toxic components leading to large scale mortalities of marine life are relatively rare, localised and short-lived. Sub-lethal effects that impair the ability of individual marine organisms to reproduce, grow, feed or perform other functions can be caused by prolonged exposure to a concentration of oil or oil components far lower than will cause death...

Alcohol

Death by asphyxiation occurs when alcohol depresses the body's reflexes to the point that you cant vomit right. Another thing that comes along with binge drinking is depression and suicide. You get depressed so you drink and since alcohol is a depressant it brings you down even more it brings you to the state of hopelessness. The toxic effects of alcohol can manipulate you brains neuro-transmitters, which are responsible for mood and judgement. This can plung you into deeper depression and bring thought about suicide. It can also bring a cycle of drinking: the more you drink the more depressed you become, and that makes you want to drink more. Alcohol induced depression and hopelessness are characterized by self-pity, social withdrawal, self reproah,a sence of guilt,and a retardation of normal mental processes....

All offer some advantages and may not always be used interchangeably. The knowledge of the most effective ion spectrum is still in an embryonic stage. Good units generate large amounts of small and intermediate ions in differing proportions and without a perceptible increase of undesirable byproducts as ozone and nitrous compounds in toxic or even irritating amounts..............................................................................................................16 For experimental work, two separate units for production of (-) or (+), or one permitting a reversion of polarities with a controlled output in excess of 100,000 ions per cc. of air, measured at a distance of six feet, are indispensable.

Some people say that every body should do voluntary work for

give something back to it. This is easy when just start doing something. If nobody doesn't drop junk on the ground then that's a good thing to. Also should take part on different trees planting and junk cleaning events. I guess that government and local authorities should make more and more with that kind of purpose events. At this evolution period can people buy also cars witch waist less environment. When going to tank a car then should take with less toxic fuel. What less we use electricity helps on saving environment. But when we don't do these simple things then eventually our children don't have a place to born....

Inglisekeelne lühiessee tuumaelektrijaamade vajalikkusest

Nuclear Power: A Burden or a Blessing? Today, when the pollution of Earth is an important matter, people are trying to find economic solutions to produce power. This is where the necessity of nuclear power plants comes in question. Nuclear power plants are a cheap way to generate electricity but it also brings a lot of pollution that is much more radioactive and toxic than, for example, coal waste. But if we are looking at the facts, burning coal pollutes the Earth much more than nuclear power plants because more waste is generated. CO2, which is released from burning coal, is the main cause of global warming. Nuclear waste is collected and hidden in rocks or under ground, where it won't face the environment. However we shouldn't depend on nuclear energy as Uranium reserves are ending,...

E-book – the book of the future

). Because of the high-tech appeal of the e-reader, e-books are a greater target for theft than an individual print book. Along with the theft of the physical device, any e-books it contains also become stolen. If a e-book is stolen, accidentally lost, or deleted, in the absence of a backup it may have to be repurchased. Environmental Concerns - E-book readers require various toxic substances, the disposal of their batteries in particular raises environmental concerns. Certainly it will take time to get used to new things, but as for me, I believe that most of the disadvantages of e-books will be overcome and step by step they will replace the conventional books. And maybe people of my generation will retell their grandchildren unbelievable stories about reading paper books instead of digital versions....

Ohtlikud jäätmed

Tekkivatest ohtlikest jäätmetest moodustavad 94%-98% nn. suuremahulised jäätmed, mis tekkivad põlevkivienergeetika ja põlevkivikeemia tööstuse protsesside tulemusel väga suurtes kogustes. Kui välja arvata suuremahulised jäätmed siis jäävad järele mujal ettevõtluses ja kodumajapidamistes tekkivad ohtlikud jäätmed mille tekkekogust Eestis hinnatakse umbes 20 tuh. tonnile aastas. Kusjuures Tallinn koos Harjumaaga on piirkond kus selliseid ohtlike jäätmeid tekkib Eestis kõige enam, mis on tingitud ettevõtluse ja tööstuse kogunemisest Tallinna ümbrusse. JS § 6. Ohtlikud jäätmed (1) Ohtlikud jäätmed on jäätmed, mis vähemalt ühe käesoleva seaduse §s 8 nimetatud kahjuliku toime tõttu võivad olla ohtlikud tervisele, varale või keskkonnale. JS § 8.

Part II, Theories of Meaning, surveys the competing theories of linguistic mean- ing and compares their various advantages and liabilities. Part III, Pragmatics and Speech Acts, introduces the basic concepts of linguistic pragmatics, includes a detailed discussion of the problem of indirect force and surveys approaches to metaphor. Part IV, new to this edition, examines the four theories of metaphor. Features...

Wind energy vs oil shale

Calculations have shown that if new oil shale blocks were built, it would cost 3473 million EEK in a year per capita. On the other hand, if wind power were renewed in similar amount, it would cost only 868 million EEK per capita in a year. It means that if the wind power were renewed, it would be 17 370 millions EEK cheaper. The fact that wind energy saves resources and produces neither dangerous emissions nor toxic waste is also in favour of wind energy. Power from oil shale In the time when many world countries close factories that use fossil fuels, Estonia is starting to build new factories that work with oil shale. Taxpayers pay subsidy for oil shale in every year unconditionally the amount electricity produced and also when it is known that this source of energy has no perspective. Also it is not economically useful to produce electricity from oil shale...
