Crystals

... 30 wt%. The purity of the product is often higher than 99.9 wt%. To obtain this purity an efficient solid-liquid separation is of major importance, because the themselves are almost pure. To optimize the separation efficiency large with a small size distribution have to be formed. The operation of crystallization is exacting. Large—capacity evaporators are not suited to the careful control and flexible manipulation required for a successful ‘strike’, or actual crystallization, of solid sugar . For this purpose, the concentrated liquor ...

The Ozone Layer

... presents the earth’s average ground temperature of 15 degrees Celsius would fall to -28 degrees Celsius. The termed greenhouse effect implies that a comparable effect keeps the interior of the green house warm. Actually, the man role of the glass in a green house is to prevent convection currents from mixing cooler air outside with the warmer air inside. Although water is the most important factor in the greenhouse effect, is a major reason why human regions experience less cooling at night than do dry regions. Changes in both water a ...

The Quicksilver

... of work went into developing a good use to mercury- thermometers. Before people had been developing thermometers but they were not as accurate as the ones produced around 1900. In the later twentieth century people developed a increasing "need" for pure gold and silver. European and American scientists developed a new advanced way for this- amalgams. Amalgams are alloys of mercury usually used to extract elements from there various ores. Then, once the common metal is extracted mercury is then separated through distillation. Without mercur ...

The Monkey

... are predominantly arboreal, leaping from limb to limb in their travels among the trees. On the ground they walk in plantigrade fashion (the entire sole of the foot touching the ground); but they are capable of sitting upright and sometimes standing erect, and consequently their hands are freed for many manipulative tasks. Most have a short, relatively flat face without great prominence of the muzzle (excepting the baboons and drills). The hands and feet are prehensile, with, typically, five digits on each, the first (thumb and big toe) b ...

Cold Fusion

... on the border of legitamete science, or is it a practical field worthy of serious attention? is the merging of two dissimilar metal hydrides. The process is exothermic, and can generate energy in one of two ways. Energy can be input in to a system and multiplied, or energy alone can be generated although in a much smaller amount. For example, one watt of energy can be input and 3 watts recovered. Some systems are capable of producing hundreds of watts per individual watt. The actual physics of the reaction is not completely understo ...

Hydroponics Growing Without Soil

... the 1940’s at Purdue University, Robert B. and Alice P. Withrow developed another hydroponic method. Their process was called Nutriculture. Nutriculture varied from Dr. Gericke’s method in that gravel was used as a rooting medium. After World War II a number of commercial installations were built in the United States. The majority of these were located in Florida. Most were out of doors and subject to the rigors of the weather. Poor construction techniques and operating practices caused many of them to be unsuccessful an ...

The Atomic Bomb

... this project the Manhatten Project. This project was headed by six of the worlds best scientists: Neils Bohr, Joseph Carter, Enrico Fermi, Richard Feyman, and Robert Oppenheimer, each with their own ideas of what it would take to construct such a weapon. From left to right: Neils Borh, Robert Oppenheimer, Richard Feyman, Enrico Fermi The object of the project was to produce a practical military weapon in the form of a bomb in which the energy would be released by a fast neutron chain reaction in one or more of the materials known to show ...

Geneticists

... bachelor degree can get a job, but I myself would advise getting the highest amount of bioscience education possible. Jobs can be acquired by asking your professors, but, they may not be aware of any need for geneticists. Many times, reading advertisements may of some good. You may even make an appointment with biology and genetic firms yourself. Sometimes clinics or hospitals may even need a genetic specialist. I, myself, could also see a geneticist opening up his own clinic, such as radiologists do. In this way they could be a ...

Polio

... headache, fever, vomiting, constipation, stiffness of the neck, or, less commonly, diarrhea and pain in the extremities. Because nerve cells that control muscular movement are not replaced once they are destroyed, virus infection can cause permanent paralysis. When nerve cells in respiratory centers, which control breathing, are destroyed, the victim must be kept alive by an iron lung (see Artificial Respiration). For every paralytic case of myelitis, however, there may be 100 nonparalytic cases. Treatment Because no drug developed so far h ...

Origanum Vulgare

... medicines were invented for stomachaches, oregano was used for minor food poisonings and convulsions. Externally, oregano was used on skin irritations to cease the itch. The French included it in soaps and pomades. The Greeks crowned newlyweds with oregano and planted it on graves as well as using the herb medically. Oregano’s German name, wurstkraut, reveals its use of seasoning sausages. The English used oregano for perfumes, washing waters, and used it for dyes to turn wool purple and linen reddish brown. In good health and quality, oreg ...

Black Holes

... is the black hole theory. Not any star can become a Black Hole. For instance, the possibility of our sun becoming a black hole is highly unlikely, simply because it is too small. Only a very large star has the potential to become a black hole. The definitions of black boles are somewhat sceptical. Generally, a black hole is an area of super-concentrated mass. So concentrated, that no object can escape its gravitational pull. In other words, once you get caught by it’s graviational pull, you aren’t getting out again. The velocity you ...

Augiga The Charioteer

... north to south, most of the more interesting aspects of the constellation are found to the south of the star, all the way down to El Nath, the second brightest star (gamma Auriga) which is actually shared with Taurus, and also known as beta Taurus. Auriga's stars are fairly bright; five are second magnitude or brighter. Alpha Auriga (Capella) is the sixth brightness star, at a visual magnitude of 0.08. The star is 43.5 light years away, and is about ten times the size of our Sun. Capella's visual magnitude is really the combined ...
