Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test. Vitamin B12 deficiency can be caused by many factors, one of which is pernicious anemia, a condition resulting in deficient production of intrinsic factor in the parietal cells of the stomach. Intrinsic factor is a protein that is needed to assist in the absorption of vitamin B12 into the small intestine.
Vacuum forming offers processing advantages over competitive processes such as fabrication, blow molding, injection blow molding, rotational molding, and injection molding. Because tooling costs are lower, relatively large parts can be economically fabricated.acuum forming offers processing advantages over competitive processes such as fabrication, blow molding, injection blow molding, rotational molding, and injection molding.

Vacuum forming is a process where sheets of plastic are heated to the point that they become pliable, allowing them to be formed around a plug or male mold. It is so simple, that people can actually take on smaller jobs, such as making masks for costuming, right from their home without the need for expensive equipment.
