Developments in Steam Turbines for the Sugar Industry

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.

Phytoestrogens: recent developments

Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...

Avoiding Stressed-Out Steam Turbines

assembly, Pro/ENGINEER CAD geometry was imported into ANSYS Mechanical software and meshed using SOLID185 elements. Frictionless surface-tosurface contact pairs with augmented Lagrangian algorithms were created between mating surfaces. A matching node pattern was maintained at the root and slot pressure faces, where load transfers take place between the two components. As an in-house design pra...

Recent Developments in Discrete Event Systems

This article is a brief exposure of the process approach to a newly emerging area called "discrete event systems" in control theory and summarizes some of the recent developments in this area. Discrete event systems is an area of research that is developing within the interstices of computer, control and communication sciences. The basic direction of research addresses issues in the analysis an...
