Buch. Zustand: Neu. Neuware - All living cells are surrounded by a lipidic membrane that isolates them from the often harsh environment. However, to take up nutrients, to excrete waste, and to communicate among each other, Nature has invented an incredibly diverse set of transmembrane transport proteins. Specialized transporters exist to shuttle electrically charged ions, positive cations like sodium or negative anions like chloride, across the membrane. In the recent years, tremendous progress has been made in the field of chloride transport. The present book presents the state of the art of this rapidly expanding and interest-gaining field of membrane transport. It is addressed at a broad medically, physiologically, biologically, and biophysically interested readership.…

Buch. Zustand: Neu. Neuware - The second volume of the Handbook of Defense Economics addresses defense needs, practices, threats, and policies in the modern era of globalization. This new era concerns the enhanced cross-border flows of all kinds (e.g., capital and labor flows, revolutionary rhetoric, guerrillas, and terrorists) including the spillovers of benefits and costs associated with public goods and transnational externalities (i.e., uncompensated interdependencies affecting two or more nations). These ever-increasing flows mean that military armaments and armies are less able to keep out security threats. Thus, novel defense and security barriers are needed to protect borders that are porous to terrorists, pollutants, political upheavals, and conflicts. Even increased trade and financial flows imply novel security challenges and defenses. Globalization also underscores the importance of a new set of institutions (e.g., the European Union and global governance networks) and agents (e.g., nongovernmental organizations and partnerships).This volume addresses the security challenges in this age of globalization, where conflicts involve novel tactics, new technologies, asymmetric warfare, different venues, and frightening weapons. Volume 2 contains topics not covered in volume 1 - i.e., civil wars, peacekeeping, economic sanctions, the econometrics of arms races, conversion, peace economics, and the interface of trade, peace, and democracy. Volume 2 also revisits topics from volume 1, where there has been a significant advancement of knowledge - i.e., conflict analysis, terrorism, arms races, arms trade, military manpower, and arms industries. All of the main securities concerns of today are analyzed. Chapters are written by the leading contributors in the topic areas.\*Up-to-date surveys on the pressing defense issues: theoretical, empirical and policy issues.\*Coverage of theoretical and empirical studies of terrorism.\*Contributions by the leading researchers in the field of defense economics.…

Buch. Zustand: Neu. Neuware - Quantitative Structure-Activity Relationship (QSAR) for Pesticide Regulatory Purposes stems from the experience of the EC funded project DEMETRA. This project combined institutes involved in the regulatory process of pesticides, industries of the sector and scientists to develop and offer original software for the prediction of ecotoxicity of pesticides. Then to be used within the dossier preparation for pesticide registration. The basis of this book is more than three-years of research activities, discussions, studies and successful models. This experience represents a useful example not only for the case of pesticides, but also for the prediction of ecotoxicity and toxicity in general. QSAR is used to link a given property of a chemical compound with some features related to its structure. The theoretical toxicological, chemical and information technology aspects will be treated considering the regulatory issues. Innovative hybrid systems will be described, for the toxicity prediction of pesticides and related compounds, directly useful for pesticide evaluation within the Dossier preparation for pesticide registration. Five endpoints will also be discussed, addressing issues as standardisation, verification, validation, accessibility, reproducibility. The driving force for Quantitative Structure-Activity Relationship (QSAR) for Pesticide Regulatory Purposes is that all the issues of concern for end-users are analysed, discussed and solutions proposed further. An innovative feature is that, in order to offer powerful QSAR models, the book discusses and reports on integrated QSAR models, combined into a unique hybrid system.\* Assesses the needs of regulators for pesticide approval and how these needs affect QSAR models\* Combines theoretical discussion with practical examples, including five worked examples of hybrid systems\* Refers to original software available through the internet.…

Buch. Zustand: Neu. Neuware - Radicals for Life: the Various Forms of Nitric Oxide provides an up-to-date overview of the role of nitrosocompounds and nitrosyl-iron complexes in physiology. Nitrosocompounds can be considered as stabilised forms of nitric oxide, one of the most important regulatory molecules in physiology today. Many nitrosocompounds share some of the physiological functions of nitric oxide, and may be formed inside living organisms. This is the first book to be published that is dedicated to the role of such nitrosocompounds in physiology, with particular emphasis on the nitrosocompounds that are endogenously formed in higher organisms and humans. Points of discussion include: physical and chemical properties of the compounds, the main chemical pathways in vivo, as well as the physiological effects that have been recognised to date. Each of the nineteen chapters is written by distinguished specialists in the field, well known for their original and important contributions to the subject. Also included are results from a wide range of studies in vitro, in cell cultures, animal models and human volunteers. Examples of alternative forms of nitric oxide, with special emphasis on their protective role against widespread human diseases like atherosclerosis, Alzheimer's disease, diabetes, sexual dysfunction, and renal insufficiency to stroke and ischemia are also included. First monograph to consider and provide an overview of endogenous nitrosocompounds and nitrosyl-iron complexesExtensive bibliographic references, written by specialists of human physiologyProviding high scientific quality with a focus on implications for human diseases.…

Buch. Zustand: Neu. Neuware - Chromium nutritional supplements are the second best selling mineral supplements after calcium as chromium is found in pills, sports drinks, chewing gums, smoothies, and numerous other products. Chromium has been promoted to promote weight loss and muscle development and most recently to be available to treat the symptoms of type 2 diabetes and related conditions. The aim of The Nutritional Biochemistry of Chromium(III) is to examine the four most controversial areas of chromium nutrition and biochemistry: - is chromium an essential element for humans and are chromium nutritional supplements of value - what biochemical role, if any, does chromium play in the body - can large doses of chromium(III) be used to treat symptoms of type 2 diabetes, cardiovascular disease, and related medical conditions - is the use of chromium(III) supplements a health concern. Scientific experts, who are recognized leaders in the field, weigh in with their opinions on both sides of these issues in this book.A background review of the field from 1955-1995 by Vincent opens the book and concludes with a summary by Dr. Forrest Nielsen, Center Director of the USDA's Grand Forks Human Nutrition Research Center concludes the book.…
