Buch. Condición: Neu. Neuware - Over the past 25 years, the molecular electrostatic potential has become firmly established as an effective guide to molecular interactions. With the recent advances in computational technology, it is currently being applied to a variety of important chemical and biological systems. Its range of applicability has expanded from primarily a focus on sites for electrophilic and nucleophilic attack to now include solvent effects, studies of zeolite, molecular cluster and crystal behavior, and the correlation and prediction of a wide range of macroscopic properties. Moreover, the increasing prominence of density functional theory has raised the molecular electrostatic potential to a new stature on a more fundamental conceptual level. It is rigorously defined in terms of the electron density, and has very interesting topological characteristics since it explicitly reflects opposing contributions from the nuclei and the electrons.This volume opens with a survey chapter by one of the original pioneers of the use of the electrostatic potential in studies of chemical reactivity, Jacopo Tomasi. Though the flow of the succeeding chapters is not stringently defined, the overall trend is that the emphasis changes gradually from methodology to applications. Chapters discussing more theoretical topics are placed near the end. Readers will find the wide variety of topics provided by an international group of authors both convincing and useful.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book explains, in concise chapters, the diversity and complexity of what is known concerning human responses to vibration. The book covers both whole body vibration and hand-transmitted vibration and contains pictorial models of the relevant variables, as well as experimental data and epidemiological studies. The study of human vibration incorporates psychology, mathematics, physiology, engineering, medicine, and statistics, and the Handbook of Human Vibration is written to assist both students of the subject and those addressing practical problems. The text does not depend on an advanced knowledge of mathematics or a familiarity with the jargon from the various disciplines, and is accessible to all persons interested in human vibration, including medical doctors, engineers, lawyers, scientists, trade union officials and administrators. 988 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Neuropeptide Y (NPY) is a ubiquitous and important messenger in the nervous system, with a wide range of physiological roles. It is involved in the body energy balance and is one of the most potent stimuli of food intake known. NPY also acts to regulate central and peripheral autonomic functions. This book, written by academic and industrial experts in the field, links the most recent basic experimental knowledge about NPY and its receptors with areas of clinical importance. This book will be of interest to those working in all areas of research affected by NPY, such as food intake and energy homeostasis, cardiovascular regulation and G-protein-coupled receptors, as well as those interested in the development of drugs as NPY targets. 209 pp. Englisch.…
