ArabChitin is a versatile environmentally friendly modern material. It has a wide range of applications in areas such as water treatment, pulp and paper, biomedical devices and therapies, cosmetics, membrane technology and biotechnology and food applications. Crustacean waste is the most important chitin source for commercial use. Demineralization is an important step in the chitin purification process from crustacean waste. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 8,799 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHormesis: Principles and Applications for Pharmacology and ToxicologyEdward J. CalabreseThe present assessment places hormetic dose responses within an historical context, documenting its origin, rejection by the biomedical community during the early decades of the 20th due to its close association with homeopathy and its revitalization during the later decades of the past century as the biomedical and toxicological communities became very interested in low dose effects of drugs and … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 8,210 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMethodology of Compliant Mechanisms and its Current Developments in Applications: A ReviewSolehuddin Shuib, M.I.Z. Ridzwan, A. Halim KadarmanTraditional rigid-body mechanisms consist of a number of components to implement their functions. Therefore they face problems such as backlash, wear, increase in part-count, weight, assembly cost and time, regular maintenance. Reducing these problems will help in increasing mechanism performance and cost reduction. Recently, there are several examples of compliant mechanisms that have been designed and widely used in various … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,676 accessesView PDFCite
