Die Gleichungen der Physik: Meilensteine des Wissens
by Sander BaisSeit Jahrtausenden versuchen wir, die Natur zu verstehen. Wir konnten einige der grossen Mysterien enträtseln, die uns umgeben, indem wir den Makro- und Mikrokosmos mit immer raffinierteren Werkzeugen untersuchen. Nicht nur, dass wir dabei eine überwältigende Vielfalt an Fakten gesammelt haben, wir enthüllten sogar Grundgesetze, welche die Struktur und Entwicklung der physikalischen Realität steuern. Insbesondere lernten wir aus diesen Beobachtungen, dass die Natur sich uns in der Sprache der Mathematik mitteilt. Die künstlichste aller Sprachen wird so zur natürlichsten. Die Gesetze stellen sich uns als Gleichungen dar, vielleicht der kompakteste und eindeutigste Ausdruck menschlichen Wissens. Dieses Buch ist ein Reiseführer zu den Gleichungen, den Meilensteinen des Wissens, die entscheidende Wendepunkte unseres Verständnises markieren.Wir wandern vom Herzstück der klassischen Physik, den Gesetzen von Newton und Maxwell, einerseits zu Einsteins scharfsinnigen Erkenntnissen über die Struktur von Raum und Zeit, und andererseits zu den Gleichungen von Schrödinger und Dirac und dem Standardmodell der Elementarteilchenphysik, das die Türen zum Mikrokosmos öffnete. Am Ende stehen wir vor den Super-Strings als mögliche Grundlage einer allumfassenden Theorie.
The Scientific View of Sport: Perspectives, Aspects, Issues
by H. Baitsch H. E. Bock M. Bolte W. Bokler O. Grupe H. W. Heidland F. Lotzprogress and happiness - however these terms may be understood in detail - as a significant and constitutive element of scientific inquiry. In this sense the question of the way in which sport really benefits people and contributes to their happiness, and under which individual and social conditions, is a scientific question. It assumes special significance when the fact is taken into account that in the field of sport science a general scepticism is shown towards those dogmas and pedagogical theses which take such an interpretation for granted in the absence of a firm empirical foundation and a critically evolved theory. Sport and Sport Science Sport and exercise, physical culture and education in sport (physical training), gymnastics and touring combined with some form of sport are-as the present report distinctly shows-all over the world among the most striking social phenom ena of today. At first sight they seem to be uncomplicated, clear and comprehensible for everybody; they stand for a type of solidarity which is independent of differences in ideological-political outlook, and sometimes exhibit an almost archaic intensity and attraction; they are supported by the active participation or at least the interest of very many people in many parts of the world and are endued with specific func tions, varying in importance, of a medical (therapeutical, prophylactic, rehabilitative), pedagogical, psychological and social character.
Spin Glasses: Criticality and Energy Landscapes (Springer Theses)
by Marco Baity JesiThis thesis addresses the surprising features of zero-temperature statics and dynamics of several spin glass models, including correlations between soft spins that arise spontaneously during avalanches, and the discovery of localized states that involve the presence of two-level systems. It also presents the only detailed historiographical research on the spin glass theory. Despite the extreme simplicity of their definition, spin glasses display a wide variety of non-trivial behaviors that are not yet fully understood. In this thesis the author sheds light on some of these, focusing on both the search for phase transitions under perturbations of Hamiltonians and the zero-temperature properties and responses to external stimuli. After introducing spin glasses and useful concepts on phase transitions and numerics, the results of two massive Monte Carlo campaigns on three-dimensional systems are presented: The first of these examines the de Almeida–Thouless transition, and proposes a new finite-size scaling ansatz, which accelerates the convergence to the thermodynamic limit. The second reconstructs the phase diagram of the Heisenberg spin glass with random exchange anisotropy.
Quality and Reliability in Analytical Chemistry
by George E. Baiulescu Raluca-Ioana Stefan Hassan Y. Aboul-EneinQuality and reliability are central to success in every discipline, but perhaps nowhere are they more important or more interconnected than in the practice of analytical chemistry. Here, although reliable analytical information implies quality, not all "quality" information proves reliable.Quality and Reliability in Analytical Chemistry examine

Somatic Embryogenesis and Synthetic Seed I (Biotechnology in Agriculture and Forestry #30)
by Professor Dr. BajajWhile working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, for micro propagation, genetic transformation, cryopreservation, and conservation of germplasm. The en masse production of somatic embryos in the bioreactors has facilitated some of these studies. Somatic embryos have now been induced in more than 300 plant species belonging to a wide range offamilies. It was therefore felt that a compilation ofliterature/state of the art on this subject was necessary. Thus, two volumes on Somatic Embryo genesis and Synthetic Seed have been compiled, which contain 65 chapters contributed by International experts. Somatic Embryogenesis and Synthetic Seed I comprises 31 chapters, arranged in 3 sections: Section I Commitment of the cell to somatic embryogenesis; early events; anatomy; molecular basis; gene expression; role of polyamines; machine vision analysis of somatic embryos. Section II Applications of somatic embryos; technology of synthetic seed; fluid drilling; micropropagation; genetic transfor mation through somatic embryos; cryopreservation.

Crops I (Biotechnology in Agriculture and Forestry #2)
by Y. P. BajajProduction of food to meet the demands of an ever-increasing human population in the world is the major task and challenge to agriculture today. The conventional methods of plant breeding alone can no longer cope with the situation. The success of any crop improvement program depends on the extent of genetic variability in the base population, but due to denuding of forests and agricultural land, the naturally occurring pool of germplasm is being depleted. An urgent need is therefore ap parent to create new variability and increase the genetic base of agricul tural crops. Agricultural biotechnology has progressed to a stage in the produc tion of plants where specific characteristics to improve their yield, ap pearance, disease-resistance, nutritional quality and adaptation to ad verse soil conditions can be built into the seed. This concept of built-in quality implies a continuous scientific endeavour to improve plant char acters using a wide range of possibilities, and it also implies a scrutiny of the materials and methods available in the world today.
Cryopreservation of Plant Germplasm I (Biotechnology in Agriculture and Forestry #32)
by Y. P. BajajThe germ plasm of numerous plant species, especially those of forest trees, some agricultural crops, and medicinal plants, is endangered and threatened with extinction. This depletion of germplasm pools and the shrinkage of naturally occurring genetic resources have caused international concern. Conventionally, the germplasm of plants is conserved through seeds, tubers, roots, corms, rhizomes, bulbs, cuttings, etc. However, the germ plasm of a number of trees and plantation crops (such as coconut, cocao, coffee, oil palm, rubber, mango, horse chestnut, etc. ) cannot be preserved since their seed are short-lived (recalcitrant). Likewise, germplasm of vegetatively propagated crops (such as potato and cassava) cannot be stored on a long term basis and has to be grown and multiplied periodically in nurseries and fields. The plants are thus exposed to unpredictable weather conditions and diseases, with the result that instances are known where entire genetic stocks are lost. Therefore, unconventional methods are being developed for the storage and international exchange of germplasm. For this purpose in vitro cultures have been employed, but they can only enable short-to medium term preservation; moreover, cell cultures upon repeated subculture undergo genetic erosion. In view of the recent developments in the in vitro induction of genetic variability through somaclonal variation, somatic hybridization, recombinant DNA technology, etc. , new methods need to be employed for the storage of desirable cultures. In this regard freeze preservation of cells in liquid nitrogen (-196 0q, like that of semen, enables long-term storage, theoretically, for an indefinite period of time.
Haploids in Crop Improvement I: From Fundamentals to Quantum Computing (Biotechnology in Agriculture and Forestry #12)
by Y. P. BajajHaploid plants have the gametophytic number of chromosomes. They are of great importance, especially in studies on the induction of muta tions and also for the production of homozygous plants, they are needed in large numbers. The conventional methods employed by plant breeders for their production are cumbersome, time-consuming, laborious and rather inefficient. Sometimes it may take years to produce a pure line. However, with the introduction of in vitro techniques, especially anther culture for the induction of androgenesis, it has become increasingly evi dent that these methods considerably accelerate the production of haploids for plant breeding programs. During the last decade, in vitro-produced haploids have been incor porated into breeding programs of many agricultural crops, and positive results have been obtained especially with rice, wheat, potato, barley, maize, asparagus, sunflower, brassica, tobacco, etc. Among these, rice and wheat are the best examples in which a number of improved varieties have been released. In wheat, the breeding cycle can be shortened by three or four generations when the pollen haploid breeding method is used instead of conventional cross-breeding. The release of the wheat varieties Jinghua 1 and Florin is a typical example of what can be achieved with other crops. Taking these developments into considera tion, the present volume, Haploids in Crop Improvement I, was compil ed.
