In recent years, the new integrated circuit technology has spawned the
development of many low cost high performance microcontrollers. With the
improvement in the processor speed, instruction sets, and memory capacities,
these microcontrollers are ideal for the implementation of Control-Oriented
Local Area Networks (COLAN) for real-time distributed control systems. The...
Early studies on the biosynthesis of Sarubicin A, 1, had suggested the
intermediacy of the novel aromatic amino acid 6-hydroxyanthranilic acid,
17. To investigate the biosynthetic steps beyond 17, [¹³C-¹⁵N carboxamide]
6-hydroxyanthranilamide, 27a, was synthesized, and fed to fermentations
of Streptomyces helicus. Incorporation of 27a into 1 provided suggestive
The portion of the Oregon coast extending from Cape Blanco south into California has long been recognized as a distinct physiographic region, with probable ramifications for prehistoric subsistence and settlement patterns. Several researchers have proposed models outlining a greater reliance upon marine/littoral resources among groups within this region, while more...
