Grundversorgung, Barmherzigkeit und Elendsverwaltung im Modus der Tafelnor allem ihr affirmativer, Elend mildernder und zugleich verfestigender Charakter diskutiert. Dies wird vor dem Hintergrund der These einer Zwei-Klassen-Sozialarbeit getan und es werden historische Vorläufer betrachtet um das Phänomen kulturell einzuordnen.冬眠 发表于 2025-3-27 14:04:51

in conjunction with a lecture course...In this third edition additional comments are made, whenever necessary, to deepen the subject. Also, connecting remarks between the chapters are made to homogenize the book. As far as possible we eliminated the obvious typos. The index is expandedaccording to the text. .978-3-030-30261-0978-3-030-30259-7insightful 发表于 2025-3-28 01:17:00
Christine Hohmann-Dennhardtws at high Reynolds numbers, one finds that flow phenomena such as the Karman vortex street, visually perceivable thanks to flow visualization techniques, lose their “regularity,” i.e. stochastic fluctuations of all flow properties are observed, as indicated in Fig. 18.2. These fluctuations occur su粘连 发表于 2025-3-28 05:09:53

Sabine Pfeifferas detected. This can be understood graphically by considering that all surface forces acting on a non-viscous fluid element act normal to the surface and as a resultant go through the center of mass of the fluid element. At the same time, the inertia forces also act on the center of mass, so that n金盘是高原 发表于 2025-3-28 12:50:12
Rudolf Martenss fluids have . as a characteristic property. Shear forces imposed on a solid from outside lead to inner elastic shear stresses which prevent irreversible changes of the positions of molecules of the solid. When, in contrast, external shear forces are imposed on fluids, they react with the build-up
