Computational Fluid Dynamics research, especially for aeronautics, continues to be a rewarding and industrially relevant field of applied science in which to work. An enthusiastic international community of expert CFD workers continue to push forward the frontiers of knowledge in increasing number. Applications of CFD technology in many other sectors of industry are being successfully tackled. The aerospace industry has made significant investments and enjoys considerable benefits from the application of CFD to its products for the last two decades. This era began with the pioneering work ofMurman and others that took us into the transonic (potential flow) regime for the first time in the early 1970's. We have also seen momentous developments of the digital computer in this period into vector and parallel supercomputing. Very significant advances in all aspects of the methodology have been made to the point where we are on the threshold of calculating solutions for the Reynolds-averaged Navier-Stokes equations for complete aircraft configurations. However, significant problems and challenges remain in the areas of physical modelling, numerics and computing technology. The long term industrial requirements are captured in the U. S. Governments 'Grand Challenge' for 'Aerospace Vehicle Design' for the 1990's: 'Massively parallel computing systems and advanced parallel software technology and algorithms will enable the development and validation of multidisciplinary, coupled methods. These methods will allow the numerical simulation and design optimisation of complete aerospace vehicle systems throughout the flight envelope'.

Peptide synthesis has emerged as one of the most powerful tools in biochemical, pharmacological, immunological, and biophysical la- ratories. Recent improvements include general solid-phase method- ogy, new protecting groups, and automated equipment. These advances have allowed the facile synthesis of increasingly more complex p- tides. Many of these new and improved methods for the synthesis of peptides and peptide-related substances have been reported in various publications, but never compiled in a convenient handbook. Like other volumes in this series, Peptide Synthesis Protocols concentrates on the practical aspects of these procedures, providing the researcher with detailed descriptions and helpful tips about potential problems. This volume is not intended to serve as a basic guide to standard Merrifie- type solid-phase strategy, but rather to provide the researcher with some of the most recent applications in the field of peptide science. A c- panion volume, Peptide Analysis Protocols, will detail methodology for the charaterization of new synthetic peptides. Development of new methods and applications has continued actively even as this volume was in preparation. Owing to the number of contributors to this volume, it was necessary to establish a cutoff for publication purposes. We feel that all of the protocols presented are timely and up-to-date. Several promising new strategies, such as allyloxycarbonyl-based syntheses, were being developed at the time this volume was in the editing stages and will be included in future editions.
The scientist' s understanding of the cell at the molecular level has advanced rapidly over the last twenty years. This improved understa- ing has led to the development of many new laboratory methods that increasingly allow old problems to be tackled in new ways. Thus the modern scientist cannot specialize in just one field of knowledge, but must be aware of many disciplines. To aid the process of investigation, the Methods Molecular Biology series has brought together many protocols and has highlighted the useful variations and the pitfalls of the different methods. However, protocols frequently cannot be simply taken from the shelf. Thus the starting sample for a chosen protocol may be unavailable in the correct state or form, or the products of the procedure require a different sort of processing. Therefore the scientist needs more detailed information on the nature and requirements of the enzymes being used. This information, though usually available in the literature, is often widely dispersed and frequently occurs in older volumes of journals; not everyone has comprehensive library facilities available. Also many scientists searching out such information are not trained enzymologists and may be unaware of some of the parameters that are important in a specific enzyme reaction.
A treatment of the experimental techniques and instrumentation most often used in nuclear and particle physics experiments as well as in various other experiments, providing useful results and formulae, technical know-how and informative details. This second edition has been revised, while sections on Cherenkov radiation and radiation protection have been updated and extended.
Professor John D. Roberts published a highly readable book on Molecular Orbital Calculations directed toward chemists in 1962. That timely book is the model for this book. The audience this book is directed toward are senior undergraduate and beginning graduate students as well as practicing bench chemists who have a desire to develop conceptual tools for understanding chemical phenomena. Although, ab initio and more advanced semi-empirical MO methods are regarded as being more reliable than HMO in an absolute sense, there is good evidence that HMO provides reliable relative answers particularly when comparing related molecular species. Thus, HMO can be used to rationalize electronic structure in 1t-systems, aromaticity, and the shape use HMO to gain insight of simple molecular orbitals. Experimentalists still into subtle electronic interactions for interpretation of UV and photoelectron spectra. Herein, it will be shown that one can use graph theory to streamline their HMO computational efforts and to arrive at answers quickly without the aid of a group theory or a computer program of which the experimentalist has no understanding. The merging of mathematical graph theory with chemical theory is the formalization of what most chemists do in a more or less intuitive mode. Chemists currently use graphical images to embody chemical information in compact form which can be transformed into algebraical sets. Chemical graph theory provides simple descriptive interpretations of complicated quantum mechanical calculations and is, thereby, in-itself-by-itself an important discipline of study.
It is now twenty years since Cohen and Boyer's first steps into DNA cloning. In the time since then, there has been an ever increasing acc- eration in the development and application of the cloning methodology. With the recent development of the polymerase chain reaction, a second generation of the technology has been born, enabling the isolation of DNA (and in particular, genes) with little more information than the p- tial knowledge of the sequence. In fact, DNA sequencing is now so advanced that it can almost be carried out on the industrial scale. As a consequence of these advances, it now appears feasible to sequence whole genomes, including one the size of the human. What are we going to do with this information? The future of basic molecular biology must lie in the ability to analyze DNA (and especially the genes within it) starting at the DNA level. It is for these problems that Protocols for Gene Analysis attempts to offer solutions. So you have a piece of DNA, possibly a gene--what do you do next? The first section of this book contains a number of "basic" te- niques that are required for further manipulation of the DNA. This s- tion is not intended to be a comprehensive collection of methods, but merely to serve as an up-to-date set of techniques. I refer you to other volumes in the Methods Molecular Biology series for further rec- binant DNA techniques.
Geophysical measurements are not done for the sake of art only. The ultimategoal is to solve some well-defined geological, tectonical or structural problems. For this purpose, the data have to be interpreted, translated, into a physical model of the subsurface. ... This book describes some ofthe most important common features of different geophysical data sets. (fromthe Introduction) Users at universities but also practitioners in exploration, physics or environmental sciences, wherever signal processing is necessary, will benefit from this textbook.

Most cells will survive removal from the natural mic- environment of their in vivo tissue and placement into a sterile culture dish under optimal conditions. Not only do they survive, but they also multiply and express differen- ated properties in such a culture dish. A few cells do this in suspension, but most will need some kind of mechanical support substituting for their natural connections with other cells. The surface of a culture dish that might have to be coated is usually sufficient. The recent trend to standa- ization of conditions and the existence of commercial ent- prises with adequate funds and specializing in the needs of scientists were responsible for the tremendous proliferation of cell culture techniques in all fields of research in the last 20 years. No longer does a scientist have to concentrate all his/her efforts on that technology; the new trends make it feasible to employ cell culture techniques as only one of the many methods available in a small corner of a larger research laboratory. Some areas of research depend more heavily than others on cell culture techniques. Neuroscience is one of the areas that has developed hand in hand with the prol- eration of cell culture methodology. Molecular biological aspects, cell differentiation and development, neurophy- ological and neurochemical studies, as well as investigations into the nature of various diseases are now to a large extent dependent on the use of cell cultures.
Nucleic acid hybridization techniques allow the detection of
specific DNA or RNA sequences. This book is a clear and concise
guide to the techniques used for preparing DNA and RNA for membrane
hybridization. These include Southern blotting of DNA, northern
blotting of RNA, dot/slot blotting, Benton-and-Davis screening of
recombinant bacteriophage and Grunstein-Hogness screening of
recombinant plasmids. It also discusses the pros and cons of using
nitrocellulose filters and nylon membranes in these procedures. The
book demystifies the laboratory manuals by explaining the rationale
for each step in the published protocols and points out potential
pitfalls with tips on how to avoid them.
This book presents a wide range of tested and proven protocols relevant to a number of fields within biotechnology used in laboratory experiments in everyday phycological (seaweed) research. A major focus will be on bioenergy related aspects of this emerging technology. These protocols will be written in a clear and concise manner using simple language permitting even nonspecialist to adequately understand the significance of this research. It will also contain all necesssary notes and guidelines for successful execution of these experiments.
This history of the thermometer includes controversy about its invention, the story of different scales, Fahrenheit and centigrade, and the history of the gradual scientific then popular understanding of the concept of temperature. Not until 1800 did people interested in thermometers begin to see clearly what they were measuring, and the impetus for improving thermometry came largely from study of the weather--the liquid-in-glass thermometer became the meteorologist's instrument before that of the chemist or physicist. This excellent introductory study follows the development of indicating and recording thermometers until recent times, emphasizing meteorological applications.

Basic principles of applied life sciences such as recombinant DNA technology is used in most life sciences industries marketing bio-formulations for designing more effective protein-based drugs, such as erythropoietin and fast-acting insulin etc. In recent times genetically engineered host cells from mammal, animal and plants are also being used in life sciences industries to manufacture biologics. This book discusses the most basic as well advanced issues on biological products for successfully managing a life sciences industry. It elucidates the life cycle of biological molecules, right from the conceptual development of different types of biopolymers, and their subsequent transfer from the conical flasks in laboratory to life sciences industries for large scale production and marketing. It focuses on sustainable longevity in the life cycle of commercial biopolymers. Cumulative facts and figures in this volume would immensely help in inspiring life sciences industry promoters to monitor value chain transfer process of biologics for better profitability. Additionally, it would serve as a perusal document for the students and researchers interested in entrepreneurial ventures or having their own start-up projects for the commercialization of biologics.

Dr. Taylor's book provides guidance for the development and implementation of a credible quality assurance program, plus it also provides chemists and clinical chemists, medical and chemical researchers, and all scientists and managers the ideal means to ensure accurate and reliable work. Chapters are presented in a logical progression, starting with the concept of quality assurance, principles of good measurement, principles of quality assurance, and evaluation of measurement quality. Each chapter has a degree of independence so that it may be consulted separately from the others.
Laboratory Statistics: Methods in Chemistry and Health Science, Second Edition, presents common strategies for comparing and evaluating numerical laboratory data. In particular, the text deals with the type of data and problems that laboratory scientists and students in analytical chemistry, clinical chemistry, epidemiology, and clinical research face on a daily basis. This book takes the mystery out of statistics and provides simple, hands-on instructions in the format of everyday formulas. Spreadsheet shortcuts and functions are included, along with many simple worked examples. This book is a must-have guide to applied statistics in the lab that will result in improved experimental design and analysis. This thoroughly revised second edition includes several new sections, more examples, and all formulas in Excel code.
Many chemists - especially those most brilliant in their field - fail to appreciate the power of planned experimentation. They dislike the mathematical aspects of statistical analysis. In addition, these otherwise very capable chemists also dismissed predictive models based only on empirical data. Ironically, in the hands of subject matter experts like these elite chemists, the statistical methods of mixture design and analysis provide the means for rapidly converging on optimal compositions. What differentiates Formulation Simplified from the standard statistical texts on mixture design is that the authors make the topic relatively easy and fun to read. They provide a whole new collection of insighful original studies that illustrate the essentials of mixture design and analysis. Solid industrial examples are offered as problems at the end of many chapters for those who are serious about trying new tools on their own. Statistical software to do the computations can be freely accessed via a web site developed in support of this book.
This book focuses on the use of novel electron microscopy techniques to further our understanding of the physics behind electron-light interactions. It introduces and discusses the methodologies for advancing the field of electron microscopy towards a better control of electron dynamics with significantly improved temporal resolutions, and explores the burgeoning field of nanooptics - the physics of light-matter interaction at the nanoscale - whose practical applications transcend numerous fields such as energy conversion, control of chemical reactions, optically induced phase transitions, quantum cryptography, and data processing. In addition to describing analytical and numerical techniques for exploring the theoretical basis of electron-light interactions, the book showcases a number of relevant case studies, such as optical modes in gold tapers probed by electron beams and investigations of optical excitations in the topological insulator Bi2Se3. The experiments featured provide an impetus to develop more relevant theoretical models, benchmark current approximations, and even more characterization tools based on coherent electron-light interactions.

G. INTRODUCTION This book is written particularly for chemists. Being one myself, I have on several occasions tried to find a book where the theory of molecular Raman spectroscopy is treated, and not being able to find one which satisfactorily answered the questions I wanted to see answered, I decided to try to write a book on it myself. Back in the middle fifties I was shown a Raman spectrum for the first time: some faint lines on a photographic plate. In the fall of 1971, during a visit to Moscow, I vividly remembered that spectrum when the son of Mandel'shtam showed me the first spectrum taken in Russia by his father and Landsberg in 1928. The spectrum of quartz photographed during January and February of that year showed the presence of some faint new lines and in later exposures these lines became stronger and stronger.
