Die Monographie enthalt Information uber die Eigenschaften der Atmospharenluft, die Verwendung der Druckluft in den technologischen Prozessen der erdolverarbeitenden Betrieben, in den Automatisierungssystemen, in Druckluftantrieben, in Druckluftmotorbauarten, in Ergebnissen der experimentellen Untersuchungen der Kolbendruckluftmotoren mit grundsatzlich neuem System der Gasverteilung – mit selbsstatigenVentilen. Es sind mathematische Modelle der Arbeitsprozesse von Druckluftmotoren, die die Dynamik der Bewegungsmechanismen, die Ergebnisse der numerischen Untersuchungen beachten, dargestellt. Es sind Empfehlungen zur Bauarterstellung von Kolbendruckluftmotoren mit selbsstatigem System der Gasverteilung gegeben. Die Monographie ist den Wissenschaftlern und Aspiranten, die sich mit der Entwicklung und Forschung der Kolbenenergieanlagen und Pneumatikeinheiten beschaftigen, zu empfohlen.

The strategy and marketing wisdom of Peter Drucker, compiled into one handy guide Peter Drucker was widely considered the father of modern management. His 39 books and countless scholarly and popular articles predicted many of the major economic developments of the late twentieth century, and his influence upon modern business is almost immeasurable. In The Strategic Drucker, Drucker associate and student Robert Swaim has distilled Drucker's most important business strategies and philosophies into one valuable book. Swaim recounts and compiles Drucker's insight on growth, strategic planning, sales, marketing, innovation, and a wealth of other vital business topics. For anyone who wants to get to know the real Drucker, without digging through all of his books and articles, The Strategic Drucker is a valuable resource. Robert Swaim, PhD (Beijing, China), has taught at numerous universities around the world and collaborated with Peter Drucker in developing an MBA and executive development program for Chinese executives and managers.

Although Peter Drucker, “The Father of Modern Management,” died in 2005, his timeless teachings are studied and practiced by forward-thinking managers worldwide. His lessons and wisdom on the topic of leadership—the central element of management—are in constant demand, yet he wrote little under that actual subject heading. In Drucker on Leadership, William A. Cohen explores Drucker’s lost leadership lessons—why they are missing, what they are, why they are important, and how to apply them. As Cohen explains, Drucker was ambivalent about leadership for much of his career, making it clear that leadership was not by itself “good or desirable.” While Drucker struggled with the concept of leadership, he was well aware that it had a critical impact on the accomplishment of all projects and human endeavors. There is no book from Drucker specifically dedicated to leadership, but a wealth of information about leadership can be found scattered throughout his 40 books and hundreds of articles. Drucker’s teachings about leadership have saved many corporations from failure and helped guide others to outstanding success. Many of the leadership concepts revealed in this book will surprise and perhaps shock Drucker’s followers. For example, who would have thought that Peter Drucker taught that “leadership is a marketing job” or that “the best leadership lessons for business or any nonprofit organization come from the military”? Written for anyone who values the insights of the man whose name is synonymous with excellence in management, Drucker on Leadership offers a deeper understanding of what makes an extraordinary leader.

All metallic materials are prepared from the liquid state as their parent phase. Solidification is therefore one of the most important phase transformation in daily human life. Solidification is the transition from liquid to solid state of matter. The conditions under which material is transformed determines the physical and chemical properties of the as-solidified body. The processes involved, like nucleation and crystal growth, are governed by heat and mass transport. Convection and undercooling provide additional processing parameters to tune the solidification process and to control solid material performance from the very beginning of the production chain. To develop a predictive capability for efficient materials production the processes involved in solidification have to be understood in detail. This book provides a comprehensive overview of the solidification of metallic melts processed and undercooled in a containerless manner by drop tube, electromagnetic and electrostatic levitation, and experiments in reduced gravity. The experiments are accompanied by model calculations on the influence of thermodynamic and hydrodynamic conditions that control selection of nucleation mechanisms and modify crystal growth development throughout the solidification process.
