Polyvinylpyrrolidone is widely used in medicine, pharmaceuticals, cosmetics, foods, printing inks, textiles, and many more diverse applications. This book describes the 50 years of research, published and unpublished, on the absorption, distribution, storage, and excretion of PVP. The toxicology of PVP is critically evaluated. The author's involvement in the recent reevaluation of PVP by the Joint Expert Committee on Food Additives of the World Health Organization (WHO) and the Food and Agriculture Organization (FOA) led them to undertake this comprehensive review of all the information on the subject. This book will be invaluable for anyone who is involved with polyvinylpyrrolidone. Included is a broad review of the toxicological studies performed on PVP, including acute, subchronic, chronic, reproductive, mutagenicity, and carcinogenicity studies. There is also an appendix listing the key studies, with references, on the absorption, renal elimination, distribution, acute toxicity, subchronic toxicity, chronic toxicity, teratogenicity, mutagenicity, and carcinogenicity of PVP.

Follows the comic adventures of the employees of the "PvP" ("Player versus Player") gaming magazine as they play the different fantasy and role-playing games that the magazine reviews; and features extras including preliminary artwork and gaming statistics.

The main aim of this Special Topics Volume is to present state of the research on the topics of characterization the modern structural materials for mechanical engineering and other areas of manufacture, latest technologies and manufacturing systems for materials processing.

Volume is indexed by Thomson Reuters CPCI-S (WoS). This compilation of 423 peer- reviewed papers is divided into chapters: Supermolecular Chemistry and Crystal Engineering; Polymer Chemistry; Physical Chemistry of Solid Surface and Catalysis; Electrochemistry; Inorganic Materials; Chiral Catalysis and Organic Synthesis; Food Chemistry; Food Flavor Chemistry and Food Sensory Science; Theoretical and Computational Chemistry; Chemical Biology and Medicinal Chemistry; Analytical Chemistry and Environmental Chemistry. The contents will interest a wide range of researchers in many fields of chemistry.

Volume is indexed by Thomson Reuters CPCI-S (WoS). Nanotechnology has been a priority research field in many countries, because new discoveries in this field have the potential power to unravel new phenomena and new principles of materials use. This collection of knowledge concerning frontier issues in nanotechnology will aid the further promotion of the integration of nanotechnology and industry.

The 4th Asia Conference on Mechanical and Materials Engineering took place July 14-18, 2016 in Kuala Lumpur, Malaysia and the objective of the conference was to share of experiences and research results and also discussion of the practical challenges in the area of materials and advanced technologies of their synthesis, manufacturing and processing. We hope this articles collection will be useful for scientists and engineers from many areas of engineering sciences.
