all her friends. Once they finally moved she went to a new school. Samantha had difficulties with making new friends. She sat alone in the canteen. She was always bullied by the big tough girls at the school. Once she stood up to them and the bad girls seemed to like her so called “sassiness”. They invited her to the back ally to “talk”, of course Sam did not know what they ment by that, so she went outside. As they were outside one of the bad girls pulled out a syringe and injected it into Samantha. She was scared to her life, that was literally the last thing she would have thought of. The bad girls only laughed, they guessed that it would be funny. But when one of the other girls injected it, she started foaming from her moth and fell down. She had an overdose. The other girls ran but Samantha quickly called for help. All Sam knows is that she was taken to a hospital.
● Drug addiction can cause serious, long-term consequences, including problems with physical and mental health, relationships, employment, and the law. Best known drugs ● Cannabis ● Heroin ● Cocaine ● LSD ● Ecstasy Cannabis ● Weed effects include losing interest in health, life, school activities, old friends and goals. Heroin ● Heroin is highly addictive and dangerous. Heroin is injected by a needle which usually is used by many addicts, which causes diseases like HIV to spread. Cocaine ● Cocaine is mostly used because of it's mental effects: intense feeling of happiness and to lose contact with reality. Cocaine is usually inhaled through the nose and it's very common in big parties. LSD ● Using LSD causes hallucinations and urge to fly or to some other dangerous activities. It is

Transistorid Laias laastus võib transe jagada 2-ks: -bipolaartransistorid, -väljatransistorid. Mõlemat liiki saab kasutusala,valmistamistehnoloogia jms järgi jagada nõrkemiseni. Näiteks on olemas madalsagedustransistorid ja kõrgsagedustransistorid, võimsustransid jne. Bipolaartranse juhitakse VOOLUGA, väljatranse aga PINGEGA. Siit tuleb suur erinevus kasutamise seisukohast - nõrka (vähe koormust kannatav allikas, mitte väikese pingega!), ntx. manetofoni või grammofoni helipea signaali on sellise transiga paha võimendada sest ta koormab signaaliallika ära. Väljatransistori puhul seda ohtu ei ole. Bipolaartransil on tavaliselt 3 otsa: - baas ehk juhtelektrood, - emmitter, - kollektor.

Water Purification What is water purification? Water purification generally means freeing water from any kind of impurity it contains, such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some contaminants, such as oil, can be settled in a settling tank. They can then be removed easily, after they have reached the bottom of the tank. Removal of dangerous microorganisms Often polluted water has to be freed from microorganisms. The water is than disinfected, usually by means of chlorination. Removal of dissolved solids Microrganisms are not only a threat to water; they can also be an advantage when it comes to ...
In a torsion-box ski, the core material is surrounded by excess material. In skis with polyurethane cores, the top fiberglass or carbon fibers. Instead of being sandwiched around the core, the layers wrap around it in what is and base layers are put into a mold, then a press, and the known as "wet wrap construction." The core is then sealed with resin and heat. This more complex manufacturing foam is injected with a hose. As it expands and hardens, the foam fuses the layers and becomes the core. process means that torsion-box skis are more expensive than laminated ones, but they provide better handling and thus are more appealing to serious skiers

1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two....
✘ Statistics show a direct relation between the consumption of food procured from intensive farming sites and an increase in the number of cancer patients and children born with defects. Researchers opine that consumption of inorganic poisonous vegetables, fruits, poultry, and meat could probably be one of the reasons for causing such damage in the human body. ✘ There are many hybrid varieties of livestock, plants, and poultry available today. The livestock and poultry are injected with hormones and other chemicals to increase the yield. Alternatives? Organic Farming: We are all well-accustomed to this concept of farming. It produces good quality food without using any chemical fertilizer or pesticides, helps reduce diseases, and lowers the environmental impact. Hydroponics: In this method, plants are grown not in the soil but in water containing dissolved nutrients in greenhouses. This technique eradicates diseases caused by soil organisms but the plant
Psychology Gleitman Blood flow in the brain during different activities: the rate of blood flow is measured by special radiation counters that are placed at various points of the skull and that monitor radiation from mildly radioactive gas injected into the bloodstream. Blood flow pattern depends on what the patient does ( different pattern is found when person is reading aloud, yet another when he watches a moving light and so on). Ambiguous sights and sounds: The way ambiguous figures are perceived often depends on what we have seen just before. For example, if we are first shown an unambiguous figure of a rat, the ambiguous picture will be seen as a rat

regenerate intact plants. Transgenic corn, rice, and soybean have been produced with 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.
In the future, we can expect deeper insights into the mechanics of how the brain works. Using one or more examples, explain effects of neurotransmission on human behavior. Acetylcholine is believed to play a role in memory formation. Martinez and Kesner carried out and experiment with the aim of determining the role of the neurotransmitter acetylcholine on memory. Rats were trained to go through a maze. Once they were able to do this two different groups of rats were injected with chemicals that either increased or decreased the activity of acetylcholine in the brain. There was also a third group, who were not injected anything. The results showed that the rats with more acetylcholine in their brain were faster in finding the food in the maze and the rats with less acetylcholine were slower and took more wrong turns. The researchers concluded that acetylcholine played an important role in creating a memory of the maze.

which accelerates the projectile along the rails, away from the power supply. There are also Lorentz forces acting on the rails and attempting to push them apart, but since the rails are mounted firmly, they cannot move. A very large power supply, providing on the order of one million amperes of current, will create a tremendous force on the projectile, accelerating it to a speed of many kilometres per second (km/s). 20 km/s has been achieved with small projectiles explosively injected into the railgun. Although these speeds are possible, the heat generated from the propulsion of the object is enough to erode the rails rapidly. Under high-use conditions, current railguns would require frequent replacement of the rails, or to use a heat-resistant material that would be conductive enough to produce the same effect. Notice that the Lorentz force is parallel to the rails, acting away from the power supply. The

· Dry steam plants - use steam piped directly from a geothermal reservoir to turn the generator turbines. The first geothermal power plant was built in 1904 in Tuscany, Italy at a place where natural steam was erupting from the earth. 45 · Flash steam plants - take high-pressure hot water from deep inside the earth and convert it to steam to drive the generator turbines. When the steam cools, it condenses to water and is injected back into the ground to be used over and over again. Most geothermal power plants are flash plants. · Binary power plants - transfer the heat from geothermal hot water to another liquid. The heat causes the second liquid to turn to steam which is used to drive a generator turbine. 13.6 Geothermal heat pumps While temperatures above ground change a lot from day to day and season to season,

It is a major but rampant mistake to treat low testosterone with external testosterone in the form of a gel or injection12 without troubleshooting the upstream parts of the axis first. It's also a mistake to think of low libido as strictly a low-testosterone problem. In 2004, I experimented with a hormone and drug called human chorionic gonadotropin, commonly known as "hCG," which e ectively acts as a form of luteinizing hormone. Injected once per week, it immediately had the e ect of more than tripling seminal volume and requiring--requiring--ejaculation three to four times per day just to think straight. If you want to kill productivity, look no further than hCG. This inconvenience was compensated for by sex with my girlfriend, which jumped from a few times a week to a few times a day. Happy days. So just inject hCG and problem solved, right? Not quite
aggression is inflicted on the self or on another. Perhaps nowhere are we brought into more dramatic contact with the un- settling side of the principle of social proof than in the realm of copycat crime. Back in the 1970S, our attention was brought to the phenomenon in the form of airplane hijackings, which seemed to spread like airborne viruses. In the 1980s, our focus shifted to product tamperings, such as the famous cases of Tylenol cap- sules injected with cyanide and Gerber baby food products laced with glass. Ac- cording to FBI forensic experts, each nationally publicized incident of this sort spawned an average of 30 more incidents (Toufexis, 1993). More recently, we've been jolted by the specter of contagious mass murders, occurring first in work- place settings and then, incredibly, in the schools of our nation. For instance, im- mediately following the bloody rampage by two Littleton, Colorado, high-school
1951); the other direction tried to follow the high new ideological demands (Evald Okas, Adamson-Eric), often resulting in dry propagandist naturalism. In the same way the theatre had to be an instrument in the hands of the Soviets for educating the nation in the new spirit. New young professionals, graduates from the Estonian State Theatre Institute founded in 1946, led by Ants Lauter and Priit Põldroos, and from the Moscow State Institute of Dramatic Art, injected new blood into the theatre. The repertoire was widening (stage versions of the novels by Tammsaare and Vilde), attention was paid to the inner problems of a human being as well as mutual relations. August Jakobson became a prominent and prolific dramatist; his plays included topics on the class struggle in pre-war Estonia, the period of collectivisation and the problems of Soviet intellectuals. In his dramas the “negative” characters appear

He was laughing when the nurse came in, brandishing a syringe. "Excuse me," she said brusquely to Edward. He got up and crossed to the end of the small room, leaning against the wall. He folded his arms and waited. I kept my eyes on him, still apprehensive. He met my gaze calmly. "Here you go, honey." The nurse smiled as she injected the medicine into my tube. "You'll feel better now." "Thanks," I mumbled, unenthusiastic. It didn't take long. I could feel the drowsiness trickling through my bloodstream almost immediately. "That ought to do it," she muttered as my eyelids drooped. She must have left the room, because something cold and smooth touched my face. "Stay." The word was slurred. "I will," he promised. His voice was beautiful, like a lullaby. "Like I said, as long as it makes you happy...
("The Lone Accordion"), the date of the World War II victory over Japan (3/9/1945, in the Continental style), and his personal keynumber (13, changed to 20 in 1956). The latter three keys generated the keys for two transpositions and the coordinates of a straddling checkerboard through a process that was complicated but that possessed a kind of tractive logic, was meant to be memorized, and probably would be after two or three run-throughs. This process injected an arbitrary five-digit number at the very beginning of the key derivation, strongly influencing the end result. (This number was also inserted in a predetermined position in the cryptogram so that the decipherer would have it. In Hayhanen's case, this position was the fifth group from the end, the position coming from the last figure, 5, of the victory date.) This group changed from message to message, so the enciphering keys, and consequently the ciphertexts of all
