Fundamentals of Electric Propulsion


Book Description

Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

The Mathematics of Diffusion


Book Description

Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.




Handbook of Hydraulic Resistance


Book Description

The handbook has been composed on the basis of processing, systematization and classification of the results of a great number of investigations published at different time. The essential part of the book is the outcome of investigations carried out by the author. The present edition of this handbook should assist in increasing the quality and efficiency of the design and usage of indutrial power engineering and other constructions and also of the devices and apparatus through which liquids and gases move.




Guide to LaTeX


Book Description

Published Nov 25, 2003 by Addison-Wesley Professional. Part of the Tools and Techniques for Computer Typesetting series. The series editor may be contacted at [email protected]. LaTeX is the text-preparation system of choice for scientists and academics, and is especially useful for typesetting technical materials. This popular book shows you how to begin using LaTeX to create high-quality documents. The book also serves as a handy reference for all LaTeX users. In this completely revised edition, the authors cover the LaTeX2ε standard and offer more details, examples, exercises, tips, and tricks. They go beyond the core installation to describe the key contributed packages that have become essential to LaTeX processing. Inside, you will find: Complete coverage of LaTeX fundamentals, including how to input text, symbols, and mathematics; how to produce lists and tables; how to include graphics and color; and how to organize and customize documents Discussion of more advanced concepts such as bibliographical databases and BIBTeX, math extensions with AMS-LaTeX, drawing, slides, and letters Helpful appendices on installation, error messages, creating packages, using LaTeX with HTML and XML, and fonts An extensive alphabetized listing of commands and their uses New to this edition: More emphasis on LaTeX as a markup language that separates content and form--consistent with the essence of XML Detailed discussions of contributed packages alongside relevant standard topics In-depth information on PDF output, including extensive coverage of how to use the hyperref package to create links, bookmarks, and active buttons As did the three best-selling editions that preceded it, Guide to LaTeX, Fourth Edition, will prove indispensable to anyone wishing to gain the benefits of LaTeX. The accompanying CD-ROM is part of the TeX Live set distributed by TeX Users Groups, containing a full LaTeX installation for Windows, MacOSX, and Linux, as well as many extensions, including those discussed in the book. 0321173856B10162003




Natural Products from Marine Microorganisms


Book Description

Natural products continue to serve as sources for the development of new medicines. There is currently a revival of interest in the discovery of bioactive compounds with new chemical structures from natural sources, largely due to the fact that synthetic libraries have not yielded the expected number of developmental candidates in the pharmaceutical industry during the last decade. In addition, the emergence of clinically relevant pathogens that are becoming increasingly resistant to currently used medicines strengthens the notion that natural product research is urgently required. Considering the fact that almost 10% of bioactive compounds are of microbial origin, and that marine microorganisms are relatively poorly studied compared to their terrestrial relatives, marine microorganisms are regarded as the most potential-laden resource for drug discovery.




Introduction to Plasma Physics and Controlled Fusion


Book Description

TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.

Learning Japanese Hiragana and Katakana


Book Description

Learning Hiragana and Katakana is a systematic and comprehensive Japanese workbook that is perfect for self-study or use in a classroom setting. Written Japanese combines three different types of characters: the Chinese characters known as kanji, and two Japanese sets of phonetic letters, hiragana and katakana, known collectively as kana, that must be mastered before the Japanese kanji can be learned. Learning Japanese Hiragana and Katakana provides beginning-level students of Japanese a thorough grounding in the basic hiragana and katakana phonetic symbols or syllabaries. A comprehensive introduction presents their primary function, origin, pronunciation and usage. The main body of the book is devoted to presenting the 92 hira and kata characters along with their variations, giving step-by-step guidelines on how to write each character neatly in the correct stroke order, with generous practice spaces provided for handwriting practice. This Japanese workbook includes: Systematic and comprehensive coverage of the two Japanese kana systems. Ample provision for Japanese kana practice, review, and self-testing at several levels Detailed reference section explaining the origin and function of kana, and the various kana combinations. Access to online Japanese audio files to aid in correct pronunciation. Helpful additional information for language students accustomed to romanized Japanese. Vocabulary selected for usefulness and cultural relevance. About this new edition: The new third edition has been expanded and revised to include many additional reading and writing exercises. Accompanying online recordings demonstrate the correct pronunciation of all the characters, vocabulary, and sentences in the book.
