Organic and medicinal chemistry are definitely the principal branches of chemistry as they are more widely studied than any other subjects in chemistry. Very often, organic and medicinal chemistry have been defined as a hybrid discipline of many other subjects that include biology, chemistry, medicine and pharmacy. The synthesis of molecules, mechanism of a process, studies of new reagents, natural products, biological and pharmacological evaluation of molecules against different components of cells are the key subjects in these two areas. On the basis of unlimited possibilities, one can imagine several scopes exist for students, researchers and industrialists to study and explore organic and medicinal chemistry. In this book, an attempt has been made to include diverse research topics to benefit the readers from different standpoints. This book has nine chapters (Volume 2) from active authors. Bhalla and his group have written two chapters in this volume. In the first chapter, Berry and Bhalla have demonstrated recent progress on the pharmacological profile of pyrazole and imidazole conjugates. In the second chapter, Kumari and Bhalla have explored the synthesis of optically active beta lactams. Sahoo and Banik have explored new quinazolines synthesis and their medicinal and pharmacological properties in Chapter Three. Perchyonok has described natural biomaterials for veterinary therapy through an in vitro approach in the fourth chapter. In the fifth chapter, Perchyonok et al. have also reported studies on cytotoxicity biomaterials containing chitosan hydrogels. Philips has demonstrated the synthesis and applications of pharmacologically relevant phosphonates and phosphinites in Chapter Six. Basu and Banik have explored apoptosis in the inhibition of cancer in Chapter Seven. Maji and Ganguly have demonstrated the use of mushrooms as a food in Chapter Eight. Bandyopadhyay et al. have studied key enzymes that are responsible in cancer and their mechanism of action in the ninth chapter. Scientists are convinced that organic and medicinal chemistry have no boundaries in science. The application of these chemical and medicinal sciences is huge and they are related to many significant discoveries. On this basis, the book will be useful for chemists, biologists, clinicians, pharmacists, biotechnologists, industrialists and engineers who are working in the field of interdisciplinary science as well as specific chemical and medicinal science.

How can leadership in service economies be developed and nurtured? This issue is of the utmost importance, because the mode of production and requirements of the leaders are different in manufacturing and service economies. While the focus in manufacturing industries is on do things right, the focus of services economies is on do the right things. In this book, the authors start out with the Service Leadership Model as well as the ingredients for Service Leadership knowledge, attitude and behaviors (i.e., skills). Second, psychometric properties of three validated measures on Service Leadership knowledge, attitude and behavior are presented. In these chapters, the internal consistency, convergent validity and factorial validity of the measures are presented. Third, the psychosocial correlates and norms associated with these three measures of Service Leadership are presented. Through these chapters, the authors attempt to establish the psychometric properties and norms of the scales assessing Service Leadership knowledge, attitude and behavior. It is their humble wish that the related work and the developed assessment tools can be used in the training, personnel decisions, intervention and research contexts.

The book called The Consolation of Philosophy was throughout the Middle Ages, and down to the beginnings of the modern epoch in the sixteenth century, the scholars familiar companion. Few books have exercised a wider influence in their time. It has been translated into every European tongue, and into English nearly a dozen times, from King Alfreds paraphrase to the translations of Lord Preston, Causton, Ridpath, and Duncan, in the eighteenth century.

In the preliminary study included in Advances in Materials Science Research. Volume 36, a novel fiberglass catalyst with highly dispersed 1-2 nm Pd clusters confined in the bulk of fiberglass at a depth of 10 nm was proposed. In spite of extremely low palladium content, this catalyst showed high performance in the selective hydrogenation of acetylene. Basic research of physicochemical properties of the silicate glass as well as the Pd/FG catalyst revealed that mass transfer of reagents in the bulk of glass does not limit the reaction rate, and the glass has a capability to absorb a large amount of polar or readily polarizable molecules like acetylene but not ethylene. In another study, vaporized materials (such as liquid vapors) were ejected through a nozzle into a vacuum, and liquid clusters with various cluster sizes were formed by adiabatic expansion. The vacuum has an important role in cluster formation, and the fundamental properties of the vacuum and clusters are described in terms of an existence in emptiness. Next, the following operations are discussed: mechanical cutting (with punching dies, guillotines, waterjets and laser beams), clamping, welding, riveting, and the coating of sheet surfaces with insulating layers. A practical laboratory stand for the examination of finished cores used in induction motors, designed by one of the authors at the Wrocław Branch of the Electrotechnical Institute, is presented. The authors deal with the issue of lead-free solders at high application temperatures, with the aim to study the effect of lanthanides addition on the properties of solders for high application temperatures. The Bi-based solders Bi11Ag2La, Bi2La, Bi2Y were designed and fabricated as innovative soldering alloys. The study of effect of lanthanides in the soldering process was especially oriented toward soldering Al2O3 and ZrO2 ceramic materials. Some examples of errors that can occur in soldering ae listed, while several selected defects are reviewed: non-wettability of the solder pads, dewetting, wrong solder mask design, warpage, head-in-pillow, cracks in the joints, pad cratering, black pad, solder beading, tombstoning, dendrites, voids, flux spattering from the solder paste, popcorning and whiskers. In closing, the authors discuss the development of processing technology for producing electrical steels with increased silicon content, which is considered one of the novel achievements in contemporary materials science dealing with magnetic materials. Commercially available steels produced by JFE Steel Corporation are analyzed.
