Neuware -Der Band « Konstitution und Vorkommen der organischen Pflanzenstoffe (exclusive Alkaloide) I) von Dr. WALTER KARRER hat rasch grossen Anklang ge funden bei den an N aturstoffen interessierten N aturwissenschaftern. Deshalb hatte Dr. KARRER geplant, einen Fortsetzungsband zu schreiben. Er hinterliess bei seinem drei Jahre nach dem Erscheinen des Buches (1958) erfolgten Tad (1961) eine schon recht umfangreiche Sammlung von Literaturnotizen. Auf An regung des Birkhauser Verlags haben die Unterzeichneten (c. H. E. seit 1962 und E. C. seit 1968) die Bearbeitung und Herausgabe eines Erganzungsbandes libernommen. Es waren mehrere Grlinde, welche uns bewogen, die Literaturzusammen stellung auf Ende 1961, das heisst auf einen Zeitraum von flinf bis sechs Jahren seit Abschluss des Hauptwerkes, zu begrenzen; genannt seien die folgenden: Der Umfang des Erganzungsbandes sollte 900-1000 Seiten nicht liberschreiten, anzustreben war erneut Vollstandigkeit, nicht Auswahl, und die Grundzlige des Hauptwerkes, namentlich sein deutlich hervortretender historischer Charak ter, sollten beibehalten werden. Die Verfasser des vorliegenden Erganzungsbandes haben bei ihren Literatur arbeiten die Originalliteratur in wahl hoherem Masse konsultiert alsDr. KARRER, der sich noch in vielen Fallen auf eingehendere und inhaltsreichere Literatur referate hatte stlitzen konnen, als dies im allgemeinen heute noch moglich ist.

Taschenbuch. Condizione: Neu. Neuware -George Britton, Synnl/Jve Liaaen-Jensen and Hanspeter Pfander This book, Volume 2 in the series Carotenoids, is the first book to be published that is devoted entirely to the total synthesis of carotenoids, but it is timely in view of the rapid development and the growing diversification of the carotenoid field. The 1971 Carotenoids book contained a major chapter of 250 pages on total synthesis by H. Mayer and O. Isler. That comprehensive and authoritative review described systematically the construction of many synthons and the synthesis of many natural and unnatural carotenoids and related compounds. Twenty five years on, that chapter remains an essential reference work and source of information, with its extensive collection of tabulated data and lists of references to the original literature. Surveys of progress since 1971 have been presented at the IUPAC International Symposia on Carotenoids and are included in the published proceedings of these symposia. The history of major publications in the carotenoid field, leading to the development of this series, was outlined in the preface to the series published in Vol. IA. The general philo sophy outlined in that preface, with emphasis on practical guidance and the inclusion of worked examples of some of the most useful procedures, is maintained in Vol. 2. In kceping with this philosophy, Vol. 2 is not intended to be an exhaustive review of the literature, but is planned as a practical book, as well as a source of information.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 384 pp. Englisch.

Inthepastfewyears, hundredsofHIVproteaseinhibitoLs have been synthesized and tested. Among these protease inhibitors, saquinavir, ritonavir, indinavir and nelfinavir have been marketed during 1995-1997. In this review, emphasis is placed on the development of HIV protease inhibitors as antiviral agents against HIV, structure-activity rela tionship (SAR) analysis ofsaquinavirand relatedcompounds, comparisonof four marketed HIV protease inhibitors, and future prospect in developing new anti-HIV drugs. 2 Introduction HIV protease inhibitors 3 HIV protease as a target for chemotherapy HIV protease was first suggested as a potential target for AIDS therapy by Kramer et a1. in 1986 [5]. HIV protease is a proteolytic enzyme responsible for cleaving large numbers of amino acid sequences. This enzyme regulates conversionoftheselargeaminoacid sequencesintobiologicallyactive struc tural and functional protein products. Specifically, HIV protease is responsi the enzymatic processing of the gagand gag-pol genes of HIV, which ble for encode for functional core proteins and viral enzymes (reverse transcriptase, ribonuclease H, integrase, and HIV protease). The polyproteins encoded by the gagand gag-pol genes undergo post-translational processing by HIV pro tease to form functional protein products as the viral particles budding out from infected cells. Therefore, inhibition of HIV protease by a protease inhibitor results in the release ofimmature, noninfectious viral particles [4]. 340 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The general principles by which the editors and authors of the present edition have been guided were explained in the preface to the first volume of Mathemat ics of the 19th Century, which contains chapters on the history of mathematical logic, algebra, number theory, and probability theory (Nauka, Moscow 1978; En glish translation by Birkhiiuser Verlag, Basel-Boston-Berlin 1992). Circumstances beyond the control of the editors necessitated certain changes in the sequence of historical exposition of individual disciplines. The second volume contains two chapters: history of geometry and history of analytic function theory (including elliptic and Abelian functions); the size of the two chapters naturally entailed di viding them into sections. The history of differential and integral calculus, as well as computational mathematics, which we had planned to include in the second volume, will form part of the third volume. We remind our readers that the appendix of each volume contains a list of the most important literature and an index of names. The names of journals are given in abbreviated form and the volume and year of publication are indicated; if the actual year of publication differs from the nominal year, the latter is given in parentheses. The book History of Mathematics from Ancient Times to the Early Nineteenth Century [in Russian], which was published in the years 1970-1972, is cited in abbreviated form as HM (with volume and page number indicated). The first volume of the present series is cited as Bk. 1 (with page numbers). 304 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Bioenergetics, the topic of volume 5 of this Series, is concerned with the energetics, the kinetics, and the mechanisms of energy conversion in biological systems. This phenomenon can be investigated on diffe rent levels of complexity. On a global level the role of biological pro cesses for the steady state of our enviroment is considered. At the physiological level, the relation between energy input and the physiolo gical state of an organism is of interest, while at the cellular level the biochemical pathways for degradation and synthesis of all relevant substrates is investigated. At present the majority of bioenergetic stu dies pertain to the molecular level. The processes in a cell are cataly zed by a large number of proteins called enzymes. The enzymes in volved in energy transduction can be considered as molecular ma chines which transform energy from one form into another, or transfer energy from one process to another. Living systems operate far from equilibrium and are open in the ther modynamic sense, i. e. they exchange energy and matter with the sur roundings. Chapter 1 presents the principles of non equilibrium thermo dynamics applied to biological systems. About 0. 05% of the energy from the sunlight which reaches the surface of the earth is used by plants and algae as well as some bacteria to synthesize organic com pounds, and thus supplies all organisms with the energy necessary for life. 542 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The finite-difference solution of mathematical-physics differential equations is carried out in two stages: 1) the writing of the difference scheme (a differ ence approximation to the differential equation on a grid), 2) the computer solution of the difference equations, which are written in the form of a high order system of linear algebraic equations of special form (ill-conditioned, band-structured). Application of general linear algebra methods is not always appropriate for such systems because of the need to store a large volume of information, as well as because of the large amount of work required by these methods. For the solution of difference equations, special methods have been developed which, in one way or another, take into account special features of the problem, and which allow the solution to be found using less work than via the general methods. This work is an extension of the book Difference M ethod3 for the Solution of Elliptic Equation3 by A. A. Samarskii and V. B. Andreev which considered a whole set of questions connected with difference approximations, the con struction of difference operators, and estimation of the ~onvergence rate of difference schemes for typical elliptic boundary-value problems. Here we consider only solution methods for difference equations. The book in fact consists of two volumes. 284 pp. Englisch.

Neuware -In this article we shall use two special classes of reproducing kernel Hilbert spaces (which originate in the work of de Branges [dB) and de Branges-Rovnyak [dBRl), respectively) to solve matrix versions of a number of classical interpolation problems. Enroute we shall reinterpret de Branges' characterization of the first of these spaces, when it is finite dimensional, in terms of matrix equations of the Liapunov and Stein type and shall subsequently draw some general conclusions on rational m x m matrix valued functions which are 'J unitary' a.e. on either the circle or the line. We shall also make some connections with the notation of displacement rank which has been introduced and extensively studied by Kailath and a number of his colleagues as well as the one used by Heinig and Rost [HR). The first of the two classes of spaces alluded to above is distinguished by a reproducing kernel of the special form K (>.) = J - U(>')JU(w)\* (Ll) w Pw(>') , in which J is a constant m x m signature matrix and U is an m x m J inner matrix valued function over ~+, where ~+ is equal to either the open unit disc ID or the open upper half plane (1)+ and Pw(>') is defined in the table below.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 560 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Series of scalars, vectors, or functions are among the fundamental objects of mathematical analysis. When the arrangement of the terms is fixed, investigating a series amounts to investigating the sequence of its partial sums. In this case the theory of series is a part of the theory of sequences, which deals with their convergence, asymptotic behavior, etc. The specific character of the theory of series manifests itself when one considers rearrangements (permutations) of the terms of a series, which brings combinatorial considerations into the problems studied. The phenomenon that a numerical series can change its sum when the order of its terms is changed is one of the most impressive facts encountered in a university analysis course. The present book is devoted precisely to this aspect of the theory of series whose terms are elements of Banach (as well as other topological linear) spaces. The exposition focuses on two complementary problems. The first is to char acterize those series in a given space that remain convergent (and have the same sum) for any rearrangement of their terms; such series are usually called uncon ditionally convergent. The second problem is, when a series converges only for certain rearrangements of its terms (in other words, converges conditionally), to describe its sum range, i.e., the set of sums of all its convergent rearrangements.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 172 pp. Englisch.

Neuware -Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. Macromolecules, essentially nucleic acids, proteins and complex carbohydrates, are the building blocks of cell structure and function. This fifth volume in the 'Bioelectrochemistry' series deals essentially with water-soluble biomacromolecules, since the properties of membrane-bound proteins are considered in other volumes of this series. The first chapter provides an extensive review of the structure, chemical reactivity and electromagnetic properties of nucleic acids. The following five chapters concentrate on proteins, their structure, folding and function, the electrochemistry of redox proteins and voltammetric methods. Special attention is devoted to the field of thiol/disulfide exchange as well as to one particular class of proteins, the iron-sulfur proteins. The last chapter considers the chemistry and properties of glycosaminoglycans, the complex charged polysaccharides of the cell surface and extracellular matrix. This series is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 404 pp. Englisch.
