This short book describes the basic technological aspects involved in the creation of purely clinch and clinch-adhesive joints made of different types of adherent materials and employing different joining technologies. Basic parameters that need to be taken into account in the design process are also presented, while a comparison of experimental testing of the hybrid joint with simple clinching for a combination of different joining materials underlines the advantages of opting for hybrid joints. The book’s conclusions will facilitate the practical application of this new fastening technology.
This volume presents treat the material science and mechanical issues of hybrid adhesive bonds which are a combination of adhesive bonding rather than mechanical fasteners. The idea of hybrid joints is to gather the advantages of the different techniques leaving out their problems. Some of the advantages of these joints are a higher static and fatigue strength and a higher stiffness with respect to simple joints, a two-stage cracking process before the final failure and improved durability. The book treats all important kinds of joints which are in use today: weld – adhesive, rivet – adhesive, clinch – adhesive, bolt – adhesive, and adhesive – adhesive. A section dedicated to threadlocking and interference-fit adhesive joints is also included. All sections are treated from a scientific point of view with modeling issues supported by simple coupons testing and a technological point of view where the idea is to present more applied results with practical cases.

Between 1939 and 1947 the county of Janów Lubelski, an agricultural area in central Poland, experienced successive occupations by Nazi Germany (1939-1944) and the Soviet Union (1944-1947). During each period the population, including the Polish majority and the Jewish, Ukrainian, and German minorities, reacted with a combination of accommodation, collaboration, and resistance. In this remarkably detailed and revealing study, Marek Jan Chodakiewicz analyzes and describes the responses of the inhabitants of occupied Janów to the policies of the ruling powers. He provides a highly useful typology of response to occupation, defining collaboration as an active relationship with the occupiers for reasons of self-interest and to the detriment of one's neighbors; resistance as passive and active opposition; and accommodation as compliance falling between the two extremes. He focuses on the ways in which these reactions influenced relations between individuals, between social classes, and between ethnic groups. Casting new light on social dynamics within occupied Poland during and after World War II, Between Nazis and Soviets yields valuable insight for scholars of conflict studies.
Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as the computational methodology of DFT.This Part II expands on the methodology and applications of DFT. Some of the chapters report on the latest developments (since the publication of Part I in 1995), while others extend the applications to wider range of molecules and their environments. Together, this and other recent review volumes on DFT show that DFT provides an efficient and accurate alternative to traditional quantum chemical methods. Such demonstration should hopefully stimulate frutiful developments in formal theory, better exchange-correlation functionals, and linear scaling methodology.
"This register of names is based on the extant death books of Auschwitz kept in the Archives of the State Museum of Auschwitz-Birkenau. In all they contain 68,864 entries. This register lists the last and first names along with the date and place of birth and the date of death as registered in the death books. The number of each entry is included to identify each one exactly." (from "Notes on the Entries" v. 2, p. 3).
