Demands for higher outputs have been met by careful tailoring of steam turbines for both mechanical and electrical power generation to meet the needs of thermal efficiency and reliability at an econoinic cost. Major system components and the methods chosen for speed control are described. Important operational requirements are featured.

-carotene has been used for years as natural food colorants and in cosmetics and healthcare due to their antioxidant property. The production of -carotene by Mucor azygosporus was evaluated, utilizing deproteinized waste whey filtrate. Since pigments are intracellular, their extraction needed after cell cultivation. In this study, different strategies for extraction of -carotene from M. azyg...

A calcium protease which degrades neurofilaments was first observed in the fan worm Myxicola infundibulum and in the squid Loligo forbesi [l] and subsequently in a mammalian system [2,3]. Many of the polypeptides in Myxicola axoplasm are degradation products of the 160 000 and 150 000 M, polypeptides as has been shown by careful peptide mapping. Moreover, there is a high probability that they r...

We analyze a model of a nonlinear bath consisting of a single two-level system coupled to a linear bath (a classical noise force in the limit considered here). This allows us to study the effects of a nonlinear, non-Markoffian bath in a particularly simple situation. We analyze the effects of this bath onto the dynamics of a spin by calculating the decay of the equilibrium correlator of the z-c...
