BACKGROUND Recent findings suggest that the North African Middle Stone Age technocomplex known as the Aterian is both much older than previously assumed, and certainly associated with fossils exhibiting anatomically modern human morphology and behavior. The Aterian is defined by the presence of 'tanged' or 'stemmed' tools, which have been widely assumed to be among the earliest projectile weapo...

Enterprise resource planning (ERP) systems are enterprise-wide information systems that automate business processes and provide global data visibility (Shen, Wall, Zaremba, Chen, & Browne, 2004; Umble, Haft, & Umble, 2003). Among its many applications, it is particularly useful in integrating the supply chain into business processes. It is important to note that the techniques and tools involve...

During the second haft of 1979, anomalously high emanation of radon was recorded at two stations of the automated radon-thoron monitoring network operated by the W. K. Kellogg Radiation Laboratory of the California Institute of Technology. The two stations exhibiting major anomalies, Kresge and Dalton Canyon, are located approximately 30 km apart on the frontal fault system of the Transverse Ra...

The elucidation of enzyme systems involved in the metabolism of fructose has done much in clarifying its metabolic pathway. Recent work (1, 2) on glucose and fructose metabolism by normal and diabetic rat livers has suggested that fructose can be metabolized by liver enzyme systems that are independent of glucose metabolism. Similar enzyme systems that act upon fructose have been reported to oc...

Profound changes in protein metabolism noted in diabetes mellitus are grossly reflected in a negative nitrogen balance. It is not clear whether this is due to depressed protein synthesis or to increased protein catabolism. Turnover studies with N15glycine have been interpreted to favor an effect on synthesis (1). Krahl (2) has demonstrated that liver slices from diabetic rats have a decreased c...
