Röntgen-Pulverdiffraktometrie: Rechnergestützte Auswertung, Phasenanalyse und Strukturbestimmung (German Edition)

Die Beugung von Röntgenstrahlen wird heute in vielen Labors zur schnellen, sicheren und zerstörungsfreien Identifikation von Festkörperproben benutzt. Der Einsatz von Kleinrechnern (PCs) und von schnelleren Detektoren hat in der Röntgenpulverdiffraktometrie zu einer Renaissance sowohl in der Phasenanalyse von Gemischen als auch in der Strukturverfeinerung aus Pulverdaten geführt.

Isotopic Landscapes in Bioarchaeology

This paintings takes a serious examine the present thought of isotopic landscapes ("isoscapes") in bioarchaeology and its software in destiny study. It particularly addresses the study strength of cremated unearths, a slightly overlooked bioarchaeological substrate, ensuing basically from the inherent osteological demanding situations and intricate mineralogy linked to it.

Storey and Y. Cook Fig. 15 This figure illustrates a plume of hot magma that may have originated from the Earth’s core beneath Gondwana and contributed to its breakup, forming the large volume of igneous rocks across Gondwana (Bryan Storey, previously published in Antarctica: Global Science from a Frozen Continent 2013, with kind permission from Cambridge University Press) with unusually large-volume volcanic events and can also be linked with continental rifting (Storey 1995).

The models use information on the timing and scale of past climate changes derived from palaeoclimate studies. Furthermore, the accuracy of the models is assessed by using the palaeoclimate evidence to evaluate or C. nz © Springer International Publishing Switzerland 2015 D.

Some climate models are now used to predict future climate change scenarios and include indications of how the large ice sheets in Antarctica will respond. Predicting future scenarios is becoming important as levels of greenhouse gases and global temperatures rise, and as scientists become increasingly concerned about the stability of the Antarctic ice sheets.
