Buch. Condizione: Neu. Neuware - Volume 14 of a series which aims to provide details of advances in stratification research from various, international, points of view.

Buch. Condizione: Neu. Neuware - This is the first volume in a series on membrane protein transfer. Membrane protein transport underlies the topological disposition of many proteins within cells and it is this disposition that allows for the co-ordination of the central cellular processes, such as metabolism.…

Buch. Condizione: Neu. Neuware - Immunoassay procedures (isotopic and non-isotopic) have become one of the single most important techniques in present-day diagnostic medicine. This book is designed as an introductory test for the staff of clinical research laboratories who conduct or intend to conduct such techniques, and will be of great value to the clinicians who make use of such services. The volume takes a three-pronged approach in it's in-depth presentation: explanation of the basic principles and applications of radioimmunoassays and non-isotopic immunoassays; practical illustrations of the various steps involved in immunoassays; discussion of the problems and pitfalls in immunoassays and how to avoid them. This fifth revised edition is a worthy successor to it's predecessors in this famous 'Laboratory Techniques' series.…

Buch. Condizione: Neu. Neuware - The origins of knowledge about the self is arguably the most fundamental problem of psychology. It is a classic theme that has preoccupied great psychologists, beginning with William James and Freud. On reading current literature, today's developmental psychologists and ethologists are clearly expressing a renewed interest in the topic. Furthermore, recent progress in the study of infant and animal behavior, provides important and genuinely new insights regarding the origins of self-knowledge.This book is a collection of current theoretical views and research on the self in early infancy, prior to self-identification and the well-documented emergence of mirror self-recognition. The focus is on the early sense of self of the young infant. Its aim is to provide an account of recent research substantiating the precursors of self-recognition and self-identification. By concentrating on early infancy, the book provides an updated look at the origins of self-knowledge.…

Buch. Condizione: Neu. Neuware - The contributions to this volume focus on selected chemical aspects of rare-earth materials. The topics covered range from a basic treatment of crystalline electric-field effects and chemical interactions in organic solvents, to separation processes, electrochemical beaviors which impact corrosion, oxidation resistance, chemical energy storage and sensor technology, and to analytical procedures.Underlying the most subtle chemical and optical properties of these elements and their compounds in the condensed state are the crystal field effects. This phenomenon in non-metallic compounds is discussed in chapter six. The volume opens with a review of important new solvent extraction procedures as well as emerging alternative separation processes such as photochemical separation, precipitation stripping and supercritical extraction. Scientific and industrial procedures are illustrated. In a further chapter eight major analytical techniques of obtaining accurate trace analysis are examined, tabulated and assessed. The most effective procedures of each are also reviewed. Chapter two considers a wide variety of methods using rare-earth solutions and slats to modify advantageously the costly deterioration of metals and alloys. This topic is expanded in the following chapter, paying particular attention to protection against high-temperature oxidation, sulfidization and hot-salt corrosion. The following two chapters are concerned with the versatility of the rare earths in addressing current technical problems such the use of rare-earth intermetallics, principally LaNi3-based materials, to provide the skyrocketing need for environmetally friendly, usually portable, battery power. The final chapter is a review of the solvation, interaction and coordination of rare-earth salts in a variety of organic solvents including dimethylacetamide, dimethylsulfoxide, various alcohols, acetonitrile and propylenecarbonate under strict anhydrous conditions. A contrast of these interactions with those in which water is present with organic solvents is also made.…

Buch. Condizione: Neu. Neuware - Volume 9 of the Handbook of Magnetic Materials has a dual purpose, as do the preceding volumes in the series. As a textbook it is intended to be of assistance to those who wish to be introduced to a given topic in the field of magnetism without the need to read the vast amount of literature published. As a work of reference it is intended for scientists active in magnetism research. To this dual purpose, Volume 9 of the Handbook is composed of topical review articles written by leading authorities. In each of these articles an extensive description is given in graphical as well as in tabular form, much emphasis being placed on the discussion of the experimental material in the framework of physics, chemistry and material science.Chapter one presents a general account of the magnetism of heavy-fermion systems. Two novel experimental techniques are described in chapters two and five. Chapter two deals with muon spin rotation and chapter five gives an account of the possibilities offered by photon beam spectroscopy. In both chapters it is shown how these sophisticated experimental methods can be used to obtain experimental information not easily obtainable by conventional experimental methods. Chapter three deals with interstitially modified intermetallic compounds of rare earth and 3d elements. Finally chapter four is concerned with thermodynamic approach to phase transitions and shows how the understanding and description of these magnetic phase transitions can be considerably enriched.…
