The resistance of high strength AISI 4340 steel tubing, quenched in oil and tempered at 425 F (218 C), to corrosive media has been investigated. The exterior surface of the specimen was exposed to boiling NaCl, the interior cavity was evacuated and t

Water tables in aquifer regions of the southwest United States are dropping off at a rate which is greater than can be replaced by natural means. It is estimated that by 1985 wells will run dry in this region unless adequate artificial recharging can

The lumen of the lateral ventricles is separated from the brain parenchyma and the circulatory system by a single layer of specialized epithelial cells, the ependyma. This ependyma is divided into choroid plexus ependymal cells, which coat the pia ar

The toxin produced by Clostridium botulinum type A is a well-known and a well-studied neurotoxin but not many of these studies have correlated the morphological changes of the bacteria with toxin production. Toxin production in type A has been relate
