Buch. Condizione: Neu. Neuware -This volume deals with the basic knowledge and understanding of fundamental interactions of low energy electrons with molecules. It pro vides an up-to-date and comprehensive account of the fundamental in teractions of low-energy electrons with molecules of current interest in modern technology, especially the semiconductor industry. The primary electron-molecule interaction processes of elastic and in elastic electron scattering, electron-impact ionization, electron-impact dissociation, and electron attachment are discussed, and state-of-the art authoritative data on the cross sections of these processes as well as on rate and transport coefficients are provided. This fundamental knowledge has been obtained by us over the last eight years through a critical review and comprehensive assessment of 'all' available data on low-energy electron collisions with plasma processing gases which we conducted at the National Institute of Standards and Technology (NIST). Data from this work were originally published in the Journal of Physical and Chemical Reference Data, and have been updated and expanded here. The fundamental electron-molecule interaction processes are discussed in Chapter 1. The cross sections and rate coefficients most often used to describe these interactions are defined in Chapter 2, where some recent advances in the methods employed for their measurement or calculation are outlined. The methodology we adopted for the critical evaluation, synthesis, and assessment of the existing data is described in Chapter 3. The critically assessed data and recommended or suggested cross sections and rate and transport coefficients for ten plasma etching gases are presented and discussed in Chapters 4, 5, and 6.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Procedures by which archaeological stone tools have been analyzed have tradition ally operated on an apprenticeship model, whereby a novice acquires competency at the elbow of a grizzled but revered expert in the field. After shuffling through literally thousands of stones and asking hundreds of questions, the neophite even tually reaches a level at which he or she can fly solo, requiring less and less attention from the Master. While this pedagogical model has been frequently tried and tested, it is not always the most efficient method, it is very labor-intensive, and it requires a resident lithics expert, a situation that often does not exist in reality. Learning the ropes would clearly be more practical if there were a manual to consult, a book that provides information and direction so that the Master might at least be spared the most elemental questions and would not have to be available all the time. For years no such manual existed, but recently the ice has been bro ken by Bill Andrefsky's Lithics: Macroscopic Approaches to Analysis, and Brian Kooyman's Understanding Stone Toolsand Archaeological Sites. These are good books, and can profitably be employed by fledgling lithic analysts. My own interest in writing a manual for stone tool analysts derives initially from the way I was trained-literally at the knees of two Masters (in this case, revered but not grizzled):Dr. Raymond R. Newell in typological and technological matters, and Dr. Ruth E. Tringham in functional studies. 284 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The exquisite binding specificity of antibodies has made them valuable tools from the laboratory to the clinic. Since the description of the murine hybridoma technology by Köhler and Milstein in 1975, a phenomenal number of mo- clonal antibodies have been generated against a diverse array of targets. Some of these have become indispensable reagents in biomedical research, while others were developed for novel therapeutic applications. The attractiveness of an- bodies in this regard is obvious-high target specificity, adaptability to a wide range of disease states, and the potential ability to direct the host's immune s- tem for a therapeutic response. The initial excitement in finding Paul Ehrlich's 'magic bullet,' however, was met with widespread disappointment when it was demonstrated that murine antibodies frequently elicit the human anti-murine an- body (HAMA) response, thus rendering them ineffective and potentially unsafe in humans. Despite this setback, advances in recombinant DNA techniques over the last 15-20 years have empowered the engineering of recombinant antibodies with desired characteristics, including properties to avoid HAMA. The ability to p- duce bulk quantities of recombinant proteins from bacterial fermentation also fueled the design of numerous creative antibody constructs. To date, the United States Food and Drug Administration has approved more than 10 recombinant antibodies for human use, and hundreds more are in the development pipeline. The recent explosion in genomic and proteomic information appears ready to deliver many more disease targets amenable to antibody-based therapy. 576 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The introduction of high-performance liquid chromatography (HPLC) to the analysis of peptides and proteins some 25 years ago revolutionized the biological sciences by enabling the rapid and sensitive analysis of peptide and protein structure through the exquisite speed, sensitivity, and resolution that can be easily obtained. Today, HPLC in its various modes has become the pivotal technique in the characterization of peptides and proteins and currently plays a critical role in both our understanding of biological processes and in the development of peptide- and protein-based pharmaceuticals. The number of applications of HPLC in peptide and protein purification continues to expand at an extremely rapid rate. Solid-phase peptide synthesis and recombinant DNA techniques have allowed the production of large quantities of peptides and proteins that need to be highly purified. HPLC techniques are also used extensively in the isolation and characterization of novel proteins that will become increasingly important in the postgenomic age. The design of multidimensional purification schemes to achieve high levels of product purity further demonstrates the power of HPLC techniques not only in the characterization of cellular events, but also in the production of pepti- and protein-based therapeutics. HPLC continues to be at the heart of the analytical techniques with which scientists in both academia and in industry must arm themselves to be able to fully characterize the identity, purity, and potency of peptides and proteins. 432 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first edition of Protein Purification Protocols (1996), edited by Professor Shawn Doonan, rapidly became very successful. Professor Doonan achieved his aims of p- ducing a list of protocols that were invaluable to newcomers in protein purification and of significant benefit to established practitioners. Each chapter was written by an ex- rienced expert in the field. In the intervening time, a number of advances have w- ranted a second edition. However, in attempting to encompass the recent developments in several areas, the intention has been to expand on the original format, retaining the concepts that made the initial edition so successful. This is reflected in the structure of this second edition. I am indebted to Professor Doonan for his involvement in this new edition and the continuity that this brings. Each chapter that appeared in the original volume has been reviewed and updated to reflect advances and bring the topic into the 21st century. In many cases, this reflects new applications or new matrices available from vendors. Many of these have increased the performance and/or scope of the given method. Several new chapters have been introduced, including chapters on all the currently used protein fractionation and ch- matographic techniques. They introduce the theory and background for each method, providing lists of the equipment and reagents required for their successful execution, as well as a detailed description of how each is performed. 500 pp. Englisch.

They are beginning to benefit from an array of costly new therapies made possible through recent rapid advances in medical science and technology, and their demands on modern medicine are rising. Meanwhile, healthcare systems are struggling with their outdated legacy models of the m- th 20 century and are experiencing ever-increasing financial pressure from g- ernments and health insurance organizations. The equation is no longer in balance, and this predicament is forcing societies to explore new approaches to managing healthcare in the future. Since the first edition of Molecular Diagnosis of Infectious Diseases was published, we have witnessed the sequencing of the (almost) complete human genome and a shift in medical research from an emphasis on genetics to the advancement and useful application of proteomics. Bioinformatics has become the key tool for managing and analyzing the upsurge of data, and faster and more effective test methods and technologies have opened up new prospects for ind- try and academia. The tools of modern genomics and proteomics are now being utilized to specifically guide the discovery of drugs for the prevention, diagnosis, and treatment of human disease. They may also help us to find a way out of the current healthcare calamity. 484 pp. Englisch.

Sulston for their seminal discoveries concerning 'genetic regulation of organ development and programmed cell death.' This clearly marked the prime importance of understanding the molecular mechanisms controlling cell death. The 1 st International Symposium on Programmed Cell Death was held in the Shanghai Science Center of the Chinese Academy of Sciences on September 8-12, 1996. A number of key issues in apoptosis were discussed at the meeting, and progress in major areas of apopto sis research was summarized by expert participants at the meeting and published by Plenum Publishing Corporation as a book entitled Programmed Cell Death. In the last six years, we have witnessed a real explosion in our knowledge on how cells undergo apoptosis, thereby participating in various developmental and pathophysiological processes. At this ever exciting time, we organized the 2nd International Symposium on Programmed Cell Death.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Since then it has been applied for the processing of many nonsulfide ores as well, including oxides, carbonates, silicates, soluble minerals like halite and sylvite and energy minerals like coal and bitumen. In recent years it has been used for several nonmineral applications, such as waste water treatment, deinking ofpaper for recycling and resource recovery from industrial wastes he technology continues to grow with new applications reportedevery year. Flotation is based on chemical phenomena occurring at the interfaces, solid/water and air/water. Surface Chemistry principles have played a significant role in the development of flotation technology. Knowledge ofaqueous solution chemistry and electrochemistry has added to our understanding ofthe reactions in flotation systems. ProfessorJan Leja's bookhas well served researchers and students as theytried to understand the chemistry of flotation, and it is a significant contribution to the advancement ofknowledge. However, since the book was first published, new research techniques and ever growing information have made an update necessary. The revised edition compiled by Dr. S. R. Rao has brought together fundamental aspects ofthe chemistryofflotation and how they apply to practical systems.
