Norther n Lights Kaisa Kask Introduction 1. How and where Northern Lights appear? 2. How the Northern Lights got their colors? 3. Do the Northern Lights emit sound? How and where Northern Lights appear? • Charged particles collide with molecules • Generate a glow • The strongest auroras are quite bright • The aurora occurs above: altitudes of 80 km infrequently above 500 km normal altitudes 110 and 200 How the Lights got their colors? • Every gas creates a different color • neon lights: helium – pink/white neon - red/orange argon - lavender krypton - gray/green The colors of auroras • Determined by gases in the Earth’s atmosphere
Lights every other clear night, if not even more frequently. From southern Norway, only a few times a month while in central Europe hardly more than a few times a year and they have even been seen from the Mediterranean but only a few times each century. To the north of the auroral zone, the Northern Lights are a common sight, although they don't appear as often as in northern Norway. What exactly are the Northern Lights? The Northern Lights occure when large numbers of electrically charged particles stream towards the Earth along its magnetic field and collide with the highest air particles. The air then lights up. The resulting colours reflect in gases we find up there, the most usual yellow-green colour is coming from oxygen. Red colouring is also due to oxygen with a contribution from nitrogen. The violet we often see is due to nitrogen, as is most blue colouring. The charged particles originate from the sun, and it is the 'weather' conditions on the sun that decide

Galactic cosmic rays (GCRs) are the high-energy particles that flow into our solar system from far away in the Galaxy. GCRs are mostly pieces of atoms:protons, electrons, and atomic nuclei which have had all of the surrounding electrons stripped during their high-speed (almost the speed of light) passage through the Galaxy. Cosmic rays provide one of our few direct samples of matterfrom outside the solar system. The magnetic fields of the Galaxy, the solar system, and the Earth have

speeds up to one thousand miles per hour at the equator of the planet ("Great Space Place"). The rings of Saturn are more spectacular than those of any other planet. Although this planet's rings are very wide, extending from the top of its atmosphere to well beyond the orbits of its closest moons, they are very thin, measuring no more than a few kilometers (about a mile) in thickness ("Great Space Place"). The Pioneer 11 flyby made several discoveries about the rings. The rings are made of particles that are dust-sized up to large mountain-sized masses, with the average size being in the marble to basketball range - about 10 centimeters (four inches). These particles are extremely cold and are possibly composed of frozen water and other ices. An extensive cloud of hydrogen was also discovered around the rings. The rings might have resulted when a moon or a passing body ventured too close to Saturn. The unlucky object would have been torn apart by great tidal

Air pollution Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. 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

Chernobyl disaster Outline • What happened? • Elimination of the consequences • The Exclusion Zone • Conclusion • Quiz • Reference list What happened? • The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe. • The Chernobyl disaster was the worst nuclear power plant accident in history in terms of cost and casualties, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011). • The battle to contain the contamination and avert a greater

The narrow southern end, especially beginning from Pähksaar Island is totally overgrown with yellow and white lilies, pondweeds, arrowhead, bulrush, and other water plants. The amount of planktonic algae can reach 30g per cubic metre, with blue- green algae prevailing in summer. Water is turbid, yellowish-green or greenish yellow, with a transparency of about 1m. Mud particles stirred up by the wave action contribute to turbidity. The zooplankton of the lake consists of smaller animals building up the summer biomass. The amount of bottom animals is low but variable in different years. pic: plaktonic algae About 35 fish species are in Lake Võrtsjärv. Pike-perch, eel, bream and pike are the most important commercial fishes. In the fifties and sixties Võrtsjärv was known as a ruff lake since inferior fish prevailed in

The conversion of nuclear mass to energy is consistent with the mass-energy equivalence formula E = m.c², in which E = energy release, m = mass defect, and c = the speed of light in a vacuum. Nuclear chemistry can be used as a form of alchemy to turn lead into gold or change any atom to any other atom (albeit through many steps). Radionuclide (radioisotope) production often involves irradiation of another isotope (or more precisely a nuclide), with alpha particles, beta particles, or gamma rays. Iron has the highest binding energy per nucleon of any atom. If an atom of lower average binding energy is changed into an atom of higher average binding energy, energy is given off. What is nuclear fusion? Nuclear fusion is the process by which multiple like- charged atomic nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei
pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because precipitation can eventually wash pollutants into streams, lakes, and rivers. Acidity itself is determined based on the pH level of the water droplets. PH is the scale measuring the amount of acid in the water and liquid. The pH scale ranges from 0 to 14 with lower pH being more acidic while a high pH is alkaline; seven is neutral. Normal rain water is
The second explosion threw out fragments from the fuel channels and hot graphite. The graphite and fuel started a number of fires, causing the main release of radioactivity into the environment. From the second to tenth day after the accident, some 5000 tonnes of boron, dolomite, sand, clay and lead were dropped on to the burning core by helicopter in an effort to extinguish the blaze and limit the release of radioactive particles. Immediate impact Most of the released gases and fallouts were deposited close by as dust and debris, but the lighter material was carried by wind over the Ukraine, Belarus, Russia and to some extent over Scandinavia and Europe. The casualties included firefighters who attended the fires. All these were put out in a few hours, but radiation doses on the first day were extremely high causing 28 deaths. Also the people involved in the clean-up received high doses of radiation.

I. ON THE NECESSITY OF THE DARK MATTER AND DARK ENERGY There are Einstein Equations for the perfect fluid together with equation of state p = p(ρ, T ) with temperature T . Latter can not vary from place and time, because the “strong equivalence principle” holds. In case of Friedmann Universe the metric contains only one unknown function (the scale factor a(t)). Therefore the number of unknowns are less, than the number of equations (because the conservation of number of particles requires the density of the perfect fluid ρ = ρ0 (a0 /a(t))3 , see also [1] or you can ask for unpublished Gauss’s theorem in the curved spacetime). Therefore, an unknown X(t, x, y, z) from Dark Matter is needed. This unknown can be the purely the Higgs Field itself [1]. The singularities are the failure of General Relativity, thus the finite Higgs Field (which acts as Dark Energy, Dark Matter) do hold the curvature from divergency [1].

When humans eat these plants or animals, the toxins inside of the things they eat can affect them. It can cause brain damage, kidney problems and even Alzheimer's disease. The countries that are producing the majority of the pollutions that causes acid rain are not that badly affected (Germany, Britain, USA). Instead the wind direction means the acid rain falls in the other places (in Europe : Scandinavia, USA; Canada) Cultural effects Acid rain and the dry deposition of acidic particles contribute to the corrosion of metals (such as bronze) and the deterioration of paint and stone (such as marble and limestone). These effects significantly reduce the societal value of buildings, bridges, cultural objects (such as statues, monuments, and tombstones), and cars. Famous buildings like the Statue of Liberty in New York, the Taj Mahal in India and St. Paul's Cathedral in London have all been damaged by this sort of air pollution.
issues like sewage treatment, ensuring that raw sewage is not released into the natural environment. Producing process Biogas is normally produced by using the excreta of animals as the source material. In most of the countries where biogas is produced, the excreta of the cattle and other farm animals are used. In India gobar or cow dung is used for the purpose of making biogas. 20% of the excreta of animals are made up of dust particles that are inorganic in nature. The percentage of the inorganic dust particles is brought down by combining water with the excreta in a 1:1 ratio. The rate of feeding of any biogas manufacturing plant that is based on dung is 3,500 kilograms per day. Under normal circumstances the microbial content of the biogas is maintained by the addition of 2% of the expended slurry of the slurry of the fresh dung. 1% calcium ammonium nitrate of the dung is combined with the slurry in such cases.

Hendrik Antoon Lorentz (18 July 1853 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect. He also derived the transformation equations subsequently used by Albert Einstein to describe space and time. Lorentz theorized that the atoms might consist of charged particles and suggested that the oscillations of these charged particles were the source of light. When colleague and former student of Lorentz Pieter Zeeman discovered the Zeeman effect in 1896, Lorentz supplied its theoretical interpretation. The experimental and theoretical work was honored with the Nobel prize in physics in 1902. Lorentz' name is now associated with the Lorentz-Lorenz formula, the Lorentz force, the Lorentzian distribution, and the Lorentz transformation. Albert Michelson
these techniques, especially electroporation. Success rates, however, are low, and the techniques not very reproducible. DNA can also be microinjected into target plant cells using very thin glass needles in a method similar to that used with animals. Microinjection, however, has produced only a few transgenic plants. The technique is laborious, technically difficult, and limited to the number of cells actually injected. Biolistics, involves accelerating very small particles of tungsten or gold coated with DNA into cells using an electrostatic pulse, air pressure, or gunpowder percussion. As the particles pass through the cell, the DNA dissolves and becomes free to integrate into the plant-cell genome. This improbable technique actually works quite well and has become, along with electroporation, one of the methodologies of choice. Biolistics has the advantage of being applicable to whole cells in suspension or to intact or sliced plant tissues
5. Mille poolest erinevad nefelomeetria ja turbidimeetria meetodid? A nephelometer [1] is a stationary or portable instrument for measuring concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam. Particle density is then a function of the light reflected into the detector from the particles. To some extent, how much light reflects for a given density of particles is dependent upon properties of the particles such as their shape, color, and reflectivity. Nephelometers are calibrated to a known particulate, then use environmental factors (k-factors) to compensate lighter or darker colored dusts accordingly. K-factor is determined by the user by running the nephelometer next to an air sampling pump and comparing results.
power. 7.1 The science of electricity In order to understand how electric charge moves from one atom to another, we need to know something about atoms. Everything in the universe is made of atoms--every star, every tree, every animal. The human body is made of atoms. Air and water are, too. Atoms are the building blocks of the universe. Atoms are so small that millions of them would fit on the head of a pin. Atoms are made of even smaller particles. The center of an atom is called the nucleus. It is made of particles called protons and neutrons. The protons and neutrons are very small, but electrons are much, much smaller. Electrons spin around the nucleus in shells a great distance from the nucleus. If the nucleus were the size of a tennis ball, the atom would be the size of the Empire State Building. Atoms are mostly empty space. Picture 7.1. Nucleaus and electrons
together it becomes clear that a certain reclassification has taken place. Collide, once used mainly of pairs of trains and ships in motion, has expanded its scope, merely as a result of technological change, so as to refer to motor vehicles and aircraft. With this momentum it has been able to achieve generalization not only to the encounter of almost any objects whose paths might cross (e.g. pedestrians, sub-atomic particles, etc.) but also to the meeting of a moving object with a static one (e.g. a car colliding with a tree). 32. Metaphor and metonymy Metaphor is a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable. Metaphors are based on resemblance. Dead metaphors are metaphors which are no longer figurative (flower-bed, blind corner) Machinery War

explosion, says Adam Burrows of the University of Arizona. Turns out it's not so simple. Simulating a supernova gobbles enormous amounts of computer power, and even the largest supercomputers can't fully reproduce an exploding star in three dimensions. But over the years the models have improved, and the shock wave scenario has fallen apart. Researchers found that less than a thousandth of a second after the shock wave is generated, a flood of tiny, nearly massless particles called neutrinos escapes from the center of the star. The neutrinos, born in the collapsing core, drain energy from the shock wave. The shock stalls, and-- at least in the computer--the supernova is a dud. Now Burrows and his colleagues are working with a computer model powerful enough to simulate how the core shakes and churns during the collapse, and they've finally seen how a collapsing star could turn around and explode. The turbulent infalling gas starts shaking the core,

Little of the red, orange and yellow light is affected by the air.However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. 5 Miks Päike on tõustes ja loojudes punakas-oranz? The most basic answer is that light is refracted by particles in the atmosphere and the red end of the spectrum is what is visible. 6 Kas lumi on valge? The reason we see snow in the first place is due to light. As snow falls through the atmosphere and lands on the ground, light is reflected off the surface of the ice crystals. Since the snow has multiple facets, some of the light is scattered. The reason we see snow in the first place is due to light. As snow falls through the atmosphere and

"kollased veed". Sinised veed esinevad toitainete vaeses ookeani avaosas või ka rannale lähematel aladel troopilistes meredes ja teatud aladel Vahemeres. Rannikuvetes valgus neeldub/hajub ei jõua sügavale, kuna vees esineb hõljum (füto- ja zooplanktoni näol), mitmesuguseid aineosakesi, (particles) ja nn. kollane aine (lahustunud orgaanilised, sealhulgas humiinained), mille jõed toovad merre. Suurematel sügavustel domineerib roheline värvus. Atlandi Ookeani Euroopa rannikul valdavad rannikuvete tüübid 1-3, eufootiline vöönd ulatub kuni 45m sügavusele. 8.- 9. rannikuvee tüüp esinevad tugevasti reostunud merelahtedes. Näiteks kasvab Põhjameres Helgolandi lähistel pruunvetikas Laminaria kuni 8 m sügavusel, sama liik ulatub Vahemeres kuni 95 m sügavusele. Väga

cells to increase attachment. PEI is a cationic polymer; the negatively charged outer surfaces of cells are attracted to dishes coated in PEI, facilitating stronger attachments between the cells and the plate. However, polyethylenimine expresses some toxicity if excess is left in solution. Transfection reagent Poly(ethylenimine) was the second polymeric transfection agent discovered, after poly-l-lysine. PEI condenses DNA into positively charged particles, which bind to anionic cell surface residues and are brought into the cell via endocytosis. Once inside the cell protonation of the amines results in an influx of counter-ions and a lowering of the osmotic potential. Osmotic swelling results and bursts the vesicle releasing the polymer-DNA complex (polyplex) into the cytoplasm. If the polyplex unpacks then the DNA is free to diffuse to the nucleus.] PEI is

Their cholesterol intake was naturally very low compared to other diet groups and they also consumed the most fiber [Table 3]. Dietary fiber is also said to help lower cholesterol levels by moving cholesterol particles out of the body and is therefore associated with a lower risk of coronary heart disease.24 Fats are an important part of a healthy diet. They give us energy and support cell growth. There are good fats in foods that our body needs, these foods also contain some essential vitamins and minerals. For example, canola oil is one of the healthy fat sources. It contains omega-3 and 6 fatty acids as well as vitamin E. Above all, foods high in
Modifiers of noun phrases. For example: We had quite a party. Modifier of adverbs – Pretty soon, smoke very heavily Postmodifying adverbs – Adverbs that follow the word it modifies. For example: The day before, the way ahead Modifier of pronouns, predeterminers, and numerals- Nearly everybody came to our party. They recovered roughly half their equipment. Virtually all the students participated in the discussion. Modifier of particles, prepositional adverbs, and prepositions- The nail went right through the wall. He made his application well within the time. He knocked the man right out. Her parents are dead against the trip. Adverbs as complements of preposition over here, near here, from abroad, till then Adverbs as an adverbial Adjuncts – When an adverb is nicely integrated into a sentence. For example: Slowly they walked back home.
The pointed chisel is used for cutting `V' grooves and inside sharp angles. When chipping steel, lubricate the chisel point with light machine oil. Don't use oil on cast iron. Files are used for cutting, smoothing or removing small amount of metal. They are made in various shapes, cuts of teeth and length. Single cut files are used for sharpening tools and finish filing. Double cut files are used for rough work and removal of metal. When filing soft metal, small particles of the metal will remain between the file teeth. This will cause the file to scratch the metal that is being worked on. To clean the teeth a file card brush is used. This is a combination wire brush and a bristle brush; the wire side is run across the file teeth and they are then cleaned off with the bristle side. Steel Wire Brushes are used for removing old paint and rust. Terminal brush is a conical brush with wavy steel bristles for cleaning clamps.
Conjuncts: She has bought a big house, so she must have a lot of money. If they open all the windows, then I'm leaving. Modifier of adjectives a) amplifiers: awfully sorry, extremely dangerous, deeply concerned, too dull b) downtoners: a bit dull, fairly small, quite normal, hardly noticeable, rather late c) emphasizers: That's just impossible. You are certainly welcome. Modifier of adverbs pretty soon smoke very heavily Modifier of particles, prepositional adverbs, and prepositions The nail went right through the wall. He made his application well within the time. He knocked the man right out. Her parents are dead against the trip. Modifier of pronouns, predeterminers, and numerals Nearly everybody came to our party. They recovered roughly half their equipment. Virtually all the students participated in the discussion. Modifier of NPs We had quite a party.
