Know about steroids




The steroids governed by schedules of controlled substances are anabolic steroids. Anabolic substances build up parts of living organisms, as opposed to catabolic substances, which decompose those parts. Anabolic steroids are abused mainly by persons desiring to increase muscle mass, such as competitive athletes and body builders. Steroids can improve muscle strength in females and in castrated males, but scientific evidence is weaker forintactmales. Still, steroids do seem to promote muscle mass, endurance,andoverallathletic performance while dosage continues. Some scientists suspect that any performance enhancement experienced from anabolic steroids comes not from muscle power but from psychological effects, with the drugs increasing a user’s aggressiveness. Anabolic steroids can produce mania, anger, impulsiveness, euphoria, and feelings of invincibility—a combination that may lead some users into harmful social interactions. The combination can produce other types of unwise behavior as well, such as extravagant expenditures of money and taking reckless physical risks


Sports governing authorities banned the use of anabolic steroids by competitors. Some athletes ignore the ban in hopes of avoiding detection. Various other drugs are prohibited as well, but in 1988 most of the failed drug tests ordered by the International Olympic Committee revealed anabolic steroids, the most common one being nandrolone.42 Below that elite level, athletic use of steroids seems uncommon. In the 1990s a study involving 58,625 college students found only 175 steroid takers to study.43 That small group also had a much higher consumption of other drugs, legal and illegal, than the average student—suggesting that the steroid abusers were predisposed to use drugs for coping with all sorts of life situations, not just sports


Anabolic steroids are related to testosterone. Most, if not all, are androgens, substances promoting male characteristics. A female who uses those drugs may develop facial hair and a deeper voice, along with unwanted changes in sexual organs. In a young person who is still growing, androgens can prematurely halt further growth and thereby cause a smaller adult stature. Among persons of either gender and any age, androgens may alter blood composition and increase the body’s retention of various minerals. That retention is not necessarily good


Anabolic steroid dependence is reported with withdrawal symptoms that can include weariness and depression. Use by a pregnant woman can permanently masculinize a female fetus. For information about specific anabolic steroids, see alphabetical listingsfor: boldenone, ethylestrenol, fluoxymesterone, methandriol, methandrostenolone, methyltestosterone, nandrolone, oxandrolone, oxymetholone, stanozolol, testolactone, testosterone, and trenbolone

How Energy conversion from coal is done?

Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...

5 TOP FACTS LIGHTHOUSES

1  The builder of the Lighthouse of Alexandria, Sostratus – disobeying orders from the pharaoh Ptolemy – engraved his name and a dedication to the sea gods on the tower base. Fame 2  The technical term for the study of lighthouses is ‘pharology’, a word derived from Pharos, the island upon which the great Lighthouse of Alexandria once stood. Academia 3  George Meade built many notable lighthouses in the US during the classical lighthouse period. He is remembered in history as the winning general in the Battle of Gettysburg. War 4  The tallest lighthouse in the world is the Yokohama Marine Tower in Yokohama, Japan. The structure fl ashes alternately green and red every 20 seconds. Tallest 5  Originally lighthouses were lit merely with open fi res, only later progressing through candles, lanterns and electric lights. Lanterns tended to use whale oil as fuel.
