... gas cylinders and cylinder packs as necessary. History of Helium Production: Government involvement in helium conservation dates to the Helium Act of 1925 which authorized the Bureau of Mines to build and operate a large-scale helium extraction and purification plant. From 1929 until 1960 the federal government was the only domestic helium producer. In 1960, Congress amended the Helium Act to provide incentives to natural gas producers for stripping natural gas of its helium, for purchase of the separated helium by the government, and for its long-term storage. With over 960 million cubic meters (34.6 bill ...

... is increasing. Consumption of alcohol is apparently on the rise in the United States, countries of the former Union of Soviet Socialist Republics, and many European nations. This is paralleled by growing evidence of increasing numbers of alcohol-related problems in other nations, including the Third World. Development Alcoholism, as opposed to merely excessive or irresponsible drinking, has been variously thought of as a symptom of psychological or social stress or as a learned, maladaptive coping behavior. More recently, and probably more accurately, it has come to be viewed as a complex disease entity in its ow ...

... plant is probably a major contribution to the increased corn output in the United States. This increased output represents a major achievement for applied genetics. In 1929 practically no hybrid corn was grown among the 100 million acres of corn in the United States. But by 1970 the vast majority of 67 million acres was planted with the hybrid variety, yielding twice as much corn. Plant breeders have a definite advantage over animal breeders, because they can often produce fertile varieties - indeed, new species - by crossbreeding between species. This is because hybrids are often polypoid. Polyploi ...

... and the pattern of the heavens, as charted in the horoscope, is the means the soul comes to know itself and its destiny. Astrology points the way to soul development and growth. The soul's strengths and weaknesses are noted in the horoscope. Life is an opportunity given to soul for further enhancement. Because the heavens are in constant motion, and because this motion is quite ordered and exact, it is possible to project the positions of the sun, moon, and planets for any given time. Astrologers use this information to draw-up a horoscope and forecast the "influences" that will affect the soul at that time. ...

... by using samples of maternal blood instead of amniotic fluid. The problem with amniocentesis is it uses a hollow needle to take fluid from the mother's uterus. The needle could damage the developing fetus if not inserted properly. Another advantage of FISH is that the parents get a much quicker test result than amniocentesis. After the sample is taken, amniocentesis can take up to three weeks before a test can be administered. With FISH, a same day result is given, which is much more convenient to the parents. Additionally, FISH is a simpler process. It uses specially prepared molecules which bind to ...

... with aluminum sulfate addition is the formation of aluminum phosphate particles that attach themselves to one another and become heavy and settle to the bottom of a clarifier. The aluminum sulfate and phosphorus mixture can then be withdrawn, thereby removing the phosphate or phosphorus from the wastewater flow. Industrial Applications: The application of this reaction to the industrial world consists of a set of processes to filter out the phosphate. The setup is the following: Purpose: Restrict phosphates to aluminum phosphates for easier disposal of phosphorus. The first step in phosphorus remova ...

... animals (livestock). In the focus of wood, there is the Western Canadian Boreal Forest which is a large producer of wood for the United States construction industry. However, climatic changes has had large and impacting effects on the construction industry. Compared to eastern Canada, the southern boreal forest region of western Canada has a relatively dry climate. Thus, drought effects are one of the major concerns being addressed by researchers in this region. climate modellers have predicted a large increase in temperature for this region, which could lead to even drier conditions and enormous stresses on vegetat ...

... Children from birth to 2 years of age are especially vulnerable to lung diseases because their lungs are not fully developed. Asthma is more likely to develop with children who breathe secondhand smoke (www.alaw.org). It can also exacerbate frequent attacks. Babies are three times more likely to die form Sudden Infant Death Syndrome (SIDS) if their mothers smoke during pregnancy. Ear infection, coughs, sore throat and even cancer can also develop if children are expose to secondhand smoke. With all these harmful to children, there are ways to protect them from it. First, as a parent, don’t smoke. If you are ...

... can't help but wonder if this "progress" has gone to far. The dropping of the atomic bombs on Japan should have caused alarms to sound in people's heads…"Danger, danger!" Just one of these bombs has the ability to wipe out an entire country. The United States did make an attempt after World War II at eliminating nuclear proliferation by proposing the Baruch Plan in the United Nations. This proposal stated that all nuclear technology and materials be placed under international ownership and that all nuclear weapons be destroyed. However, the Soviet Union feared that the United States would always have ...

... by the name of Joseph von Fraunhofer developed the spectroscope. This tool is used to beak down light in to wavelengths. Isac Newton had a mild idea of this in his day, but nothing of this accuracy or detail. The German Scientist paved the road for theoretical explanations of the star. Some of the most recent tools that have been invented to help study the sun are the coronagraph, the spectroheliograph, the magnetograph, and the spectrograph. These tools have enabled us to better understand the magnetic field of the sun and individual characteristics of the sun. Pictured above is Galileo Com ...
