Buch. Condizione: Neu. Neuware - The center of our Solar System is a star, one among billions of stars in our own galaxy. This star, which we call the Sun, gives rise to all life on Earth, is the driver of the photosynthesis in plants, and is the source of all food, energy, and fossil fuels on Earth.For us humans, the Sun as seen with the naked eye appears as a static and quiet yellow disk in the sky. However, it is in fact a stormy and variable star and contributes much more than only light and heat. It is the source of the beautiful northern and southern lights and can affect our technology-based society in many ways.The Sun is, like astronomy in general, a good entrance to natural science, since it affects us in so many ways and connects us to many other fields of science, such as physics, chemistry, biology, and meteorology.The book includes additional material on Springer Extras, a large number of animations and video material. A PowerPoint presentation of the book is also included there as a useful resource for teachers.…

Buch. Condizione: Neu. Neuware - Art, or Science Which of these is the right way to think of the field of visualization This is not an easy question to answer, even for those who have many years experience in making graphical depictions of data with a view to help people understand it and take action. In this book, Graham Wills bridges the gap between the art and the science of visually representing data. He does not simply give rules and advice, but bases these on general principles and provide a clear path between them This book is concerned with the graphical representation of time data and is written to cover a range of different users. A visualization expert designing tools for displaying time will find it valuable, but so also should a financier assembling a report in a spreadsheet, or a medical researcher trying to display gene sequences using a commercial statistical package.…

Taschenbuch. Condizione: Neu. Neuware - That residues of pesticide and other contaminants in the total environ ment are of concern to everyone everywhere is attested by the reception accorded previous volumes of 'Residue Reviews' and by the gratifying enthusiasm, sincerity, and efforts shown by all the individuals from whom manuscripts have been solicited. Despite much propaganda to the con trary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being displaced by newly developed ones more acceptable to food technologists, pharmacologists, tOxicologists, and changing pest control requirements in progressive food-producing economies. These matters arc of genuine concern to increasing numbers of gov ernmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Ade quate safety-in-use evaluations of any of these chemicals persisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.…

Taschenbuch. Condizione: Neu. Neuware - Worldwide concern in scientific, industrial, and governmental com munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on 'toxic' chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.…

Taschenbuch. Condizione: Neu. Neuware - The rapid and continuous upsurge of interesting data in the subject of tumor immunology necessitates the publication of an annual series to furnish the updated materials to the students, researchers, and clinicians in this rapidly advancing field. Concepts and methodologies are ever changing. Also, current research in tumor immunology promises to offer breakthroughs in the future. Important is the need to communicate to the right people the exact role of immunodiagnostic methods and immunological intervention in cancer preven tion and treatment. The role of immunotherapy in combination with conven tional modalities of treatment needs to be understood in its proper perspective. Oncogene, interferon, lymphokines, monoclonal antibodies, natural killer cells, platelet-mediated cytotoxicity of antibody-coated target cells, suppressor cells, platelet-derived factors, plasma-blocking factors, control of suppressor cell func tion, abrogation of plasma-blocking factors, and so forth, are some of the areas that are continually advancing. Progress in these areas will have implication in cancer therapy. Further, it is already understood that if immunocompetence of the host can be maintained at a reasonably good level, there exists the potential to increase the therapeutic indexes of conventional modalities of treatment. This series will attempt to present updated information in all these areas based on con tributed and solicited articles.…

Taschenbuch. Condizione: Neu. Neuware - International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic en vironments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on 'toxic' chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic an imals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature pro duced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching.…

Taschenbuch. Condizione: Neu. Neuware - Polymer composites were introduced for the aerospace industry as light, strong, stiff materials, and adopted by the construction and automobile industries, among others. Meanwhile, composite materials have been introduced to fulfill the uses that these conventional materials could not, such as in extreme environments. The research for new composites includes not only new polymer systems, but metals, ceramics and intermetallic systems as well. This volume contains a selection of recent work by leading researchers in micromechanics on the topics of prediction of overall properties of elastic, perfectly bonded systems, problems associated with inelastic deformation of the phase, debonding at interfaces and growth of distributed damage. Many familiar aspects of mechanical behavior, such as fatigue, fracture, strength and buckling, etc. have been reexamined and adapted for these new systems.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Here's a conundrum: the U.S. health care system is the largest sector in the biggest economy in the world, and the US spends significantly more per capita on health care than any other country. Yet it ranks last among comparison nations on the major health indicators. Robert Kaplan attempts to tackle these anomalies head-on by taking the controversial position that mass markets have been created for services that may offer little or no benefit to patients. Kaplan forcefully argues that the overuse of medications and tests runs up the costs of health care, and offers potential solutions for policy makers and for patients. 208 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Features 25 different scientists and the ideas which may not have made them famous, but made history.Typically, we remember our greatest scientists from one single invention, one new formula or one incredible breakthrough. This narrow perspective does not give justice to the versatility of many scientists who also earned a reputation in other areas of science. James Watt, for instance, is known for inventing the steam engine, yet most people do not know that he also invented the copier. Alexander Graham Bell of course invented the telephone, but only few know that he invented artificial breathing equipment, a prototype of the 'iron lung'. Edmond Halley, whose name is associated with the comet that visits Earth every 75 years, produced the first mortality tables, used for life insurances. This entertaining book is aimed at anyone who enjoys reading about inventions and discoveries by the most creative minds. Detailed illustrations of the forgotten designs and ideas enrich the work throughout. 180 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is an attempt to share some of the fascinating and exciting ideas of modern theoretical physics with a non-mathematical audience. I also hope to give some appreciation of the exceptionally creative people who have generated these ideas. I had no intention of writing a comprehen sive history of these ideas, however; I apologize to those physicists whose important contributions I may have omitted. Several people have contributed directly to the writing of this book, and I would like to take this chance to thank them. Clive Horwood of Praxis Publishing and Paul Farrell of Copernicus Books have both been supportive of the project. Anna Painter has been an exceptionally thorough editor and has provided invaluable advice. Dr John Mason and Lyman Lyons both offered constructive criticism of an early draft. The errors that remai- and errors and misinterpretations are inevitable in any attempt to explain the subtle ideas of theoretical physics without the aid of mathematics - are my sole responsibility. I would like to thank Ron, Ronnie, Peter, Jackie, Emily, and Abigail for their support. And, most importantly, I would like to thank Heike and Jessica for their patience.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Where were the amino acids, the molecules of life, created: perhaps in a lightning storm in the early Earth, or perhaps elsewhere in the cosmos This book argues that at least some of them must have been produced in the cosmos, and that the fact that the Earthly amino acids have a specific handedness provides an important clue for that explanation. The book discusses several models that purport to explain the handedness, ultimately proposing a new explanation that involves cosmic processing of the amino acids produced in space. The book provides a tour for laypersons that includes a definition of life, the Big Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the particles they produce. 228 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -'Interplanetary Outpost' follows the mission architecture template of NASA's plan for Human Outer Planet Exploration (HOPE), which envisions sending a crew to the moon Callisto to conduct exploration and sample return activities. To realize such a mission, the spacecraft will be the most complex interplanetary vehicle ever built, representing the best technical efforts of several nations. A wealth of new technologies will need to be developed, including new propulsion systems, hibernation strategies, and revolutionary radiation shielding materials. Step by step, the book will describe how the mission architecture will evolve, how crews will be selected and trained, and what the mission will entail from launch to landing. However, the focus of 'Interplanetary Outpost' is on the human element. The extended duration, logistical challenges, radiation concerns, communication lag times, isolation, and deleterious effects on the human body will conspire to not only significantly impair human performance but also affect the behavior of crewmembers. This book addresses each of these issues in detail while still providing the reader with a background to the necessary elements comprising such a mission. 284 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Before the arrival of penicillin in the 1940s, phage therapy was one of the few weapons doctors had against bacterial infections. It saved the life of Hollywood legend Tom Mix before being abandoned by Western science. Now, researchers and physicians are rediscovering the treatment, which pits phage viruses against their natural bacterial hosts, as a potential weapon against antibiotic-resistant infections.The Forgotten Cure traces the story of phages from Paris, where they were discovered in 1917; to Tbilisi, Georgia, where one of phage therapy's earliest proponents died at the hands of Stalin; to the Nobel podium, where prominent scientists have been recognized for breakthroughs stemming from phage research. Today, a crop of biotech startups and dedicated physicians is racing to win regulatory approval for phage therapy before superbugs exhaust the last drug in the medical arsenal. Will they clear the hurdles in time 148 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Topology is a relatively young and very important branch of mathematics, which studies the properties of objects that are preserved through deformations, twistings, and stretchings. This book deals with the topology of curves and surfaces as well as with the fundamental concepts of homotopy and homology, and does this in a lively and well-motivated way. This book is well suited for readers who are interested in finding out what topology is all about. Topology is a relatively young and very important branch of mathematics. It studies properties of objects that are preserved by deformations, twistings, and stretchings, but not tearing. This book deals with the topology of curves and surfaces as well as with the fundamental concepts of homotopy and homology, and does this in a lively and well-motivated way. There is hardly an area of mathematics that does not make use of topological results and concepts. The importance of topological methods for different areas of physics is also beyond doubt. They are used in field theory and general relativity, in the physics of low temperatures, and in modern quantum theory. The book is well suited not only as preparation for students who plan to take a course in algebraic topology but also for advanced undergraduates or beginning graduates interested in finding out what topology is all about. The book has more than 200 problems, many examples, and over 200 illustrations. 156 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -I wrote this book because I wanted to learn more about interstel lar flight. Not the Star Trek notion of tearing around the Galaxy in a huge spaceship-that was obviously beyond existing tech nology-but a more realistic mission. In 1989 I had videotaped Voyager 2's encounter with Neptune and watched the drama of robotic exploration over and over again. I started to wonder whether we could do something similar with Alpha Centauri, the nearest star to the Sun. Everyone seemed to agree that manned flight to the stars was out of the question, if not permanently then for the indefinitely foreseeable future. But surely we could do something with robotics. And if we could figure out a theoretical way to do it, how far were we from the actual technology that would make it happen In other words, what was the state of our interstellar technology today, those concepts and systems that might translate into a Voyager to the stars Finding answers meant talking to people inside and outside of NASA. I was surprised to learn that there is a large literature of interstellar flight. Nobody knows for sure how to propel a space craft fast enough to make the interstellar crossing within a time scale that would fit the conventional idea of a mission, but there are candidate systems that are under active investigation. Some of this effort begins with small systems that we'll use near the Earth and later hope to extend to deep space missions. 320 pp. Englisch.…

The problem is how best to identify and discover business trends and utilize trend information for attaining objectives of firms.This book contains an Excel-based solution to this problem, applying principles of the authors' 'profit system model' of the firm that enables forecasts of trends in sales, expenditures, profits and other business variables. The program, called FIRM, which runs on Windows with Microsoft Excel 2010, useshistorical time series of total sales, total costs, and total assets of the firm from its financial statements (income statements and balance sheets), estimates relationships among these variables, and then employs the estimated relationships to forecasts trends in these vital business variables. Featuring step-by-step case examples, the goal is to equip business managers and students with easy-to-use tools for understanding and forecasting trends in important business variables, thereby empowering them to make better business decisions. 60 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In most developed countries, the epidemiological disease profile has changed from infectious to degenerative, causing major alterations in epidemiological thinking and public health policies. Less developed nations have to deal with a more complex situation, because social disparities create highly unequal health conditions, the affluent being afflicted by degenerative conditions, whereas the poorer social segments continue to suffer infectious diseases, but also begin to feel the effects of chronic illness. At the turn of the 21st century, equity in health care is not being served, and social justice has lost credibility as a conceptual driving force of public health policies. Rampant injustice confirms that theories, reality and suggested practices of just social orders are flawed, leaving the needy without help or hope in a world of flagrant ethical inadequacy. And yet, mainstream bioethics loses meaning and relevance as it clings to the principle of justice and hails such concepts as global justice and universal health-care equity, misleadingly focusing on justice as a desideratum. This book pleads for an urgent turn towards directly addressing injustice as a reality that requires pressingly needed arguments and proposals to inspire realistic public health policies and programs based on an ethics of protection. Ever since Hobbes, all shades of political philosophy accept that the basic obligation of the ruling power is to protect its subjects. The ethics of protection emphasizes aiding the needy and the disempowered in obtaining access to basic goods and services related to health-care. Public health is called upon to fulfill protective obligations to guarantee disease prevention and medical services to the population, taking special care to safeguard those unable to cover their health-care needs in market-oriented medical services and institutions. The bioethics of protection developed in this text presents specific and explicit guide-lines to assure that protective public health actions be efficacious (problem-solving), efficient (sustainable cost/benefit relation) and ethically sound (respecting human rights and the common weal). These guide-lines are designed to give ethical support and justification to public health policies even when they require some unavoidable limitations of individual autonomy to promote social health benefits. 116 pp. Englisch.…
