Taschenbuch. Zustand: Neu. Neuware - Man's mind stretched to a new idea never goes back to its original dimensions Oliver Wendell Holmes Our current understanding of sex and biological differentiation results from the application of three principal experimental approaches to these subjects: those of the physiologist, the biochemist, and the geneticist. These three approaches are illustrated by the materials presented in the chapters of this volume. Chapters 1-5 emphasize conceptualization of developmental processes, describing systems principally from the standpoint of the physiologist. Structures and functions are defined with only occasional reference to specific molecular details. Chapters 6- 10 present the views of the biochemist, attempting to describe functions influ encing or regulating cellular behavior at the molecular level. And Chapters 11- 14 illustrate the approaches of the modem-day geneticist in his attempts to gain a detailed understanding of processes controlling gene expression. While it is possible to delineate these three major sections, each emphasizing a distinct experimental approach, it must be realized that the yield of knowledge increases exponentially with the number of experimental approaches available to the investigator. Information resulting from the application of each of these approaches must converge to give the same answers for anyone biological phenomenon in anyone experimental system. Further, if we can learn of details regarding a particular process by applying different experimental approaches, our postulates concerning the underlying molecular mechanisms are likely to be more accurate. But biological systems are not unrelated.…

Buch. Zustand: Neu. Neuware - ZU 'HEGEL UND DER STAAT' Der erste, der das Leben Hegels schrieb, war der Konigsberger Professor Karl Rosenkranz. Sein Buch erschien 1844. Der Verfasser hatte Hegel noch seIber gekannt. Unter den person lichen treuge bliebenen Schiilern ist er einer der freieren; ohne daB er seinen Anschauungen nach gerade der Hegelschen Linken zuzurechnen ware, ist ihm doch manches mit ihr gemein; nicht bloB eine gewisse Selbstandigkeit gegeniiber der Systematik des Meisters, sondern mehr noch eine eigentiimliche Zersplitterung und Beweglichkeit des Empfindens, ein unruhig stoffsiichtiges Hineingreifen in die Schatze der Zeit und Vergangenheit, ein starker Hang endlich zum geist reichen Widersinn stell en den Verfasser der 'Asthetik des HaBlichen' fast eher in die Reihe der StrauB, Bauer, Feuerbach als zu den Marheineke, Gabler und Henning. Sein Hegelbuch zeigt von diesen Eigenschaften verhaltnismaBig wenig; sie sind da zuriickge drangt durch die fromme Achtung des Schiilers gegen den toten Meister und wohl auch durch den Ernst des BewuBtseins, sozusagen im amtlichen Auf trag der Schule zu schreiben: die Lebensgeschichte trat an die Offentlichkeit als Erganzungsband zu den Werken. Auch die Menge handschriftlichen Stoffes, die das Buch im Abdruck oder Auszug brachte, tat das ihre, dem Verfasser den Ratim fiir seine eigenen Fliige einzuengen. Immerhin wird der Leser des noch heute unentbehrlichen und urn seiner ausgepragten und zeitcharakteristi schen Eigenart willen wohl nie ganz iiberftiissig zu machenden Buchs noch genug wunderbare Einfalle darin finden.…
