Charles Best, one of the pioneers in the search for a cure for diabetes, once explained what it is about medical research that intrigued him so. “It’s not just the gratification of knowing one is helping people,” he confided, “although that probably is a more heroic and selfless motivation. Those feelings may enter in, but truly, what I find best is the feeling of going toe to toe with nature, of trying to solve the most difficult puzzles ever devised. The answers are there somewhere, those keys that will solve the puzzle and make the patient well. But how will those keys be found?” Since the dawn of civilization, nothing has so puzzled people— and often frightened them, as well—as the onset of illness in a body or mind that had seemed healthy before. A seizure, the inability of a heart to pump, the sudden deterioration of muscle tone in a small child—being unable to reverse such conditions or even to understand why they occur was unspeakably frustrating to healers. Even before there were names for such conditions, even before they were understood at all, each was a reminder of how complex the human body was, and how vulnerable.

From his predictions about life and death in the Middle French court of Catherine de' Medici to his uncannily suggestive preconceptions of World War II, Michel de Nostradamus has aroused continual fascination-and commercialization-in the West. Today, many search his elliptical "centuries"-or collected verses-for new truths about 9/11 and End Times, while supermarket tabloids routinely falsify and exploit his pronouncements. What is the difference between prophecy and prediction, and how has it led to a misuse of the ideas of Nostradamus, as well as those of other post-biblical prognosticators? What is the nature of the oracular tradition in the West-stretching back to the oracle at Delphi-and how can Nostradamus be understood from this perspective? In The Essential Nostradamus, the highly regarded spiritual thinker and writer Richard Smoley provides a true sourcebook in the life and messages of one of history's most peculiar figures. This volume offers a host of advantages beyond other collections of Nostradamus's work. Many commentators on Nostradamus take liberties in their translations, further confusing the matter of what the prophetic quatrains actually said. In The Essential Nostradamus, Smoley presents a fresh, scholarly, and literal translation of Nostradamus's Middle French, allowing readers to make their own determination as to the passages' historical references and accuracy.

Solid-state systems are frequently classified according to their physical, structural or chemical properties. Such schemes are extremely helpful since properties related to any such classification are typically known and facilitate identifying solids with special material classes. The best-known examples of these schemes are conductivity or resistivitymeasurements bymeans of whichmetals are easily distinguishable from insulators. However, frequently clear-cut decisions between material classes are not possible, since anisotropy, chemical composition, binding forces and local effects wash out distinct properties and lead to competition or coexistence. Such unresolved situations are especially typical for transitionmetal oxides that exhibit a variety of ground-state properties in a fascinating way. Here chemical substitution, doping, pressure or temperature effects easily influence the physical properties and may, for instance, induce metal/insulator, antiferromagnet/ ferromagnet, insulator/superconductor transitions. This situation is analogous to perovskite ferroelectrics and hydrogen-bonded ferroelectrics, where ferroelectric/antiferroelectric transitions occur with chemical substitutions of one of the constituent sublattices. In addition, glass-like states (dipolar glasses) are observed and relaxor ferroelectricity with a large potential for applicationfrequently occurs.

This book provides a scientific explanation of drug abuse and addiction for the general public. It clarifies the meaning of concepts such as intoxication, physical dependence, and addiction, and describes the changes in the brain that underlie these states. Indeed, this volume is unique because it presents a comprehensive picture of what actually happens to people and their brains when they chronically self-administer opiates, stimulants or alcohol. Complex mechanisms of drug action in the brain are made simple and comprehensible to the layman through use of informative analogies and salient graphics. Accounts of the effects of drug use and abuse on normal people create meaningful, easy-to-relate-to examples from everyday life.

Вероятно, на Востоке нет другого такого явления, которое, с одной стороны, широко известно всему западному миру, но, с другой, смысл которого был бы столь туманен, как гарем. Впервые о нем мы слышали, вероятно, еще в детстве: это — место, где держат взаперти сотни красивых женщин только для того, чтобы они ублажали своего единственного властелина. Мы взрослеем, но наше представление о гареме почти не меняется. Возможно, мы даже узнаем о существовании там жен и наложниц, о том, какое положение они занимали в соответствии с традициями магометанства. Нам, не исключено, также удастся выяснить, что лишь немногие турки могли позволить себе иметь двух и более жен и слуг, числом более, чем кухарка- негритянка, выполнявшая к тому же всю работу по дому. Но почти каждый из нас по-прежнему думает, что султан — это старый греховодник, все свое время проводящий в окружении сотен полуобнаженных женщин в гареме, где стоит запах терпких ароматов, журчат прохладные фонтаны, тихо играет музыка и где он предается всяческим излишествам и порокам, какие только может придумать ради удовольствия своего повелителя коллективный разум ревнивых, изголодавшихся по мужчинам женщин.

The second half of this century has seen a pronounced escalation in the already well established sexualisation of developed capitalist societies at all structural levels, from day-to-day interactions and relationships to long-term market planning and state policy formation (Armytage et al. 1984; Gebhard 1984). Of course ‘sexuality has always been of central concern to human beings’ (Brake 1982:13) because of its associations with procreativity, its credited though usually unspecified ‘mysteries’ and apparently unsocialised animality, but never before has this concern been in explicit and coded terms, so widely and incessantly discussed, so prominently marketed and consumed, so repeatedly the site of contests over ‘permissiveness’, ‘liberation’, the pursuit or infringement of rights and freedoms.

Вольф Мессинг – одна из самых любопытных загадок XX века. Он стал знаменитым на весь мир благодаря своим уникальным способностям читать мысли, предвидеть судьбы людей, безошибочно предсказывать исторические события. Но жизнь ясновидца сложилась так, что ему не раз приходилось задумываться, божественным даром или дьявольским проклятием наделила его природа. О судьбе великого прорицателя рассказывает роман известного кинодраматурга Эдуарда Володарского.

Over the last decade, a vast evolution of communication systems was observed. The enormous popularity and expansion of the internet was a driving force for the development of broadband internet access in every home to cope with the increasing bandwidth requirements for multimedia applications. At the same time, wireless communication evolved from an analog network with large devices, to small and cheap handsets which are based on digital communication standards. The core of all these complex electronic systems consists of digital circuits which have a huge computational power and are implemented in CMOS technologies. The development of ever faster and more powerful digital cores opens the way to more complex systems with increasing demands for the analog part which has to provide an interfacing layer to the outside world. One of the crucial building blocks in the analog part is the Analog to Digital converter.

Examining the treatment in meteorological works of thermodynamical problems involving the ideas of surface tension and of adsorption, one is struck by the fact that such questions are almost always dealt with in a fragmentary manner. The reader is referred to various works which he is recommended to study in order to understand the statements presented. The multiplicity of sources on which it is desirable to draw leads him to feel the need for a general treatment, and to wish for a single account uniting in a coherent manner the variousproblems of a similar nature involving the thermodynamics of capillarity. Only an account of this kind enables one to get to the root of problems, to perceive what physical hypotheses are required in the process, and to judge the consistency or inconsistency of various theories.

Среда, окружающая человека и ограниченная помещением, имеющим определенное функциональное назначение, должна иметь такие характеристики, которые наиболее полно отвечают требованиям создания благоприятных условий жизнедеятельности и комфортных условий труда и отдыха человека. К числу характеристик, определяющих комфортные условия среды, относятся степень освещенности и микроклимат помещения, а также акустический режим, оцениваемый качеством восприятия звука, если оно обусловлено данным функциональным процессом или уровнем мешающего шума, возникающим в помещении или проникающим в него извне. Все эти вопросы являются предметом изучения строительной физики - прикладной области физики-дисциплины, тесно связанной с теорией проектирования зданий.

Jean-Jacques Rousseau wrote in his first published discourse that "we have physicists, geometers, chemists, astronomers, poets . . . but we no longer have citizens. In so doing, he pointed to a long-standing, probably eternal, problem of political life. How does an individual reconcile private capacities and goals with the duties—and opportunities—of public life? Rousseau's solution, by and large, consists of a campaign of education and socialization, reminiscent of the Spartans, to remind each and every member of the political community that the good of the community takes precedence over that of any of its members. If you are a poet, Rousseau suggests, your poetry should laud the country that enabled you to develop your gifts. If you are a chemist, your life's work should be put at the service of the community. Each person, is in a sense, public property. Whatever your particular gifts, you are first and foremost a citizen and, as such, you should not only serve the state in your particular occupation but should take an active part in its governance.
