Taschenbuch. Condición: Neu. Neuware -Australia's indigenous people, the Australians, are completely separate in the land's peoples classification. Anthropologically, Australians belong to a variant of the Australian race. Linguistically, they are also separate. Before Europeans arrived in the late 18th century, Australians were settled throughout the mainland. They numbered between 250,000 and 300,000 people at the time. The economy and culture of Australians was extremely low at that time. They lived a stray life without knowing about farming or pastoralism. Their main occupation was hunting and gathering, and occasionally fishing. Hunting was a man's business. By nature and population Oceania is divided into several parts: Melanesia (Greek 'black islands') - the westernmost and largest islands; Micronesia (Greek 'small islands') - small islands north of Melanesia; Polynesia (Greek 'many islands') - all other small islands and (in different classifications) New Zealand.

Taschenbuch. Condición: Neu. Neuware -'In the beginning, there was nothing-nothing at all anywhere. And then the sky was filled with twinkling stars, they themselves did not knew, why they were here.' All the elements which make up the so-called life on earth are truly a by-product of stellar energy sources which drive the universe. For centuries scientists looked for ways to transform the elements and in particular, to produce gold out of sand. Stars materialize this long-standing dream of the alchemists, since they synthesize heavy elements out of an inherently lighter ones. In recent years we have witnessed a reversal in the line of research, from a quest for the production of the superheavy elements on earth, how they came about, and why, the research has turned into attempts to understand what the various compositions tell us about the structure of the Universe and associated hidden reality. The aim here is not to explain each and every concept related to superheavy elements formation, but to systematically correlate some crucial aspects to provide an unshrouded glimpses of their hidden values ¿¿and probing insticts.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 68 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The implant body should be loaded in an axial direction. In a division A maxillary ridge the implant can be placed between the central fossa region and buccal cusp of the natural teeth. The buccal cusp of the natural tooth in the mandibular arch is the dominant occluding cusp. The palatal contour of the maxillary posterior implant crown is reduced to eliminate offset loads. The position of the maxillary buccal cusp should remain similar to that of the original tooth for proper esthetics and should remain out of occlusion in CR and all mandibular excursions. When further resorption occurs and the ridge evolves into division B to C bone, the maxillary palatal cusp may become the primary contact area, situated directly over the implant body. The palatal cusp angle is reduced, and a contact area is created directly over the implant abutment. Hence, the occlusal contacts differ from those of a natural tooth.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 64 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The reduction in dapped end beams depth nearby the supports tends to produce stress concentration and hence results in shear cracks, if it does not have an adequate reinforcement detailing. This study investigates numerically the efficiency of applying different external strengthening techniques to the dapped end of such beams. A twodimensional finite element model was built to predict the structural behavior of dapped ends strengthened with different techniques. The techniques included external bonding of the steel angle at the re-entrant corner, un-bounded bolt anchoring, external steel plate jacketing, exterior carbon fiber wrapping and/or stripping and external inclined steel plates. The FE analysis results are then presented in terms of the ultimate load capacities, loaddeflection and crack pattern at failure. The results showed that the FE model, at various stages, was found to be comparable to the available test data. Moreover, it enabled the capture of the failure progress, with acceptable accuracy, which is very difficult in a laboratory test.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 52 pp. Englisch.
