Druck auf Anfrage Neuware - Printed after ordering - The subject of this book is neuroendocrinology, that branch of biological science devoted to the interactions between the two major integrative organ systems of animals-the endocrine and nervous systems. Although this science today reflects a fusion…of endocrinology and neurobiology, this synthetic ap proach is relatively recent. At the beginning of the 20th century, when the British physiologists, Bayliss and Starling, first proposed endocrinology to be an independent field of inquiry, they went to great lengths to establish the autonomy of chemical secretions in general and their independence from nervous control in particular (Bayliss, W. M. , and Starling, E. H. , 1902, The mechanism of pancreatic secretion,]. Physiol. 28:325). They argued with Pav lov, who said that there was a strong influence of the nervous system on the gastrointestinal phenomena the endocrinologists were studying. For several decades, the English physiologists prevailed, at least in the West; and Pavlov's critique was not taken to heart by the practitioners of the newly emerging discipline of endocrinology. Through the work of Harris, the Scharrers, Sawyer, Everett, and others, there has been something of a scientific detente in the latter half of this century; the hybrid field of neuroendocrinology is now regarded as one of the corner stones of modern neural science and is of fundamental importance in basic and clinical endocrinology.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The subject of this book is reproduction-specifically, the interplay between reproductive physiology (especially neural and endocrine events) and behavior. In presenting this topic, there are two expository goals. The first is to study repro duction…at all of the major levels of biological organization-from the molecular (e. g. , hormone receptors in the brain), through the cellular (e. g. , ovarian morphogene sis), systemic (e. g. , operation of the hypothalamo-pituitary-ovarian axis), and the organismic levels of organization. Analogously, behavior is treated from the most molecular, elementary, and fundamental components (e. g. , copulatory reflexes), through behavior in the reproductive dyad (e. g. , analysis of female sexual behav ior), to complex social behavior (e. g. , the interaction of social context and behav ioral sex differences). To the extent that these levels of biological and behavioral organization rep resent a 'vertical axis' in behavioral neurobiology, a second goal is to treat the 'horizontal axis' of biological organization, viz. , time. There are, therefore, treat ments of evolutionary origins (e. g. , a phylogenetic survey of psychosexual differ entiation), genetic origins in the individual (e. g. , sexual organogenesis), ontoge netic development (e. g. , behavioral sexual differentiation), and the immediate physiological precursors of behavior (e. g. , hormonal and nonhormonal initiation of maternal behavior). In addition to tracing the origins of reproduction and reproductive behavior, one extends the time-line from the behavior to its physio logical consequences (e. g. , neuroendocrine consequences of sexual behavior).

In den WarenkorbThe Discovery of Nuclear Fission and of the Chain Reaction. First edition, rare, journal issues in the original printed wrappers, of the complete sequence of papers in Nature by which nuclear fission was reported, theoretically interpreted, experimentally verified, and shown to liberate enough secondary neutrons to sustain a cha…in reaction-the sequence that, between 11 February and 3 June 1939, took physics from a chemical anomaly observed in Berlin to the certainty of a feasible nuclear bomb. Three of the eight issues offered here contain Printing and the Mind of Man entries (422b, the discovery and naming of fission; 422c, its experimental confirmation; 422d, the demonstration of neutron multiplication); the remaining five are the immediately surrounding papers without which the PMM trio cannot be properly read. Together they constitute the entire foundational literature of nuclear fission, in the form in which it first reached the working physicist on his subscriber's table, and in the four-month window between the Christmas-week calculation of Meitner and Frisch in a Swedish wood and the outbreak of the Second World War in Poland fewer than thirteen weeks after the appearance of the last paper here offered. The story begins in Berlin in December 1938. Otto Hahn and Fritz Strassmann had been bombarding uranium with neutrons since 1934, hoping to produce transuranic elements. Their chemical analyses kept yielding results that made no nuclear-physical sense: among the products, in repeated and unmistakable fashion, was an isotope of barium (Z = 56), an element less than two-thirds the atomic number of uranium (Z = 92). The reigning view of nuclear processes-that a slow neutron could only nudge a heavy nucleus by a unit or two of charge through the emission of ? or ? particles-made any such large change inconceivable. Hahn, an outstanding radiochemist with no theoretical training, wrote to his former collaborator of thirty years, the physicist Lise Meitner, who had fled Berlin five months earlier as the post-Anschluss racial laws closed in on Jewish scientists, and who was now working in straitened circumstances at Manne Siegbahn's institute in Stockholm. Meitner read Hahn's letter on 21 December 1938 and could not at first make sense of the chemistry either, except in the conviction-based on thirty years of joint work-that the chemistry was right. She read the letter again over the Christmas holiday at Kungälv on the west coast of Sweden, where she was the guest of her old friend Eva von Bahr-Bergius and where she was joined by her thirty-four-year-old nephew Otto Robert Frisch, then a junior researcher at Bohr's institute in Copenhagen. The two of them went out for a walk in the snow on the morning of Christmas Day-Frisch on skis, Meitner walking briskly alongside-to talk through what could possibly be wrong with Hahn's analysis, which they were certain was not. They sat down on a tree-trunk in the woods and did the calculation together. Treating the uranium nucleus as a deformable liquid drop, in the model that George Gamow had proposed in 1928 and that Niels Bohr and Carl Friedrich von Weizsäcker had developed through the middle 1930s, they reasoned that the surface tension that ordinarily held the drop spherical would be largely cancelled by the mutual electrostatic repulsion of the 92 protons in a nucleus as heavy as uranium. The drop should be on the verge of instability with respect to even small deformations. A captured neutron might set it oscillating; the oscillation could elongate it into a dumbbell; the electrostatic repulsion could then drive the two halves apart, with the release of about 200 MeV per nucleus. Where, Frisch asked, would the energy come from? Meitner, working from memory of the empirical mass formula, calculated that the daughter nuclei would together be about one-fifth of a proton-mass lighter than the parent, and that this mass deficit, multiplied by c , gave precisely 200 MeV. The mechanism, th. Signed.
