In Situ Dose Rate Determination: First Measurements by the Use of BeO OSL Dosimeters within the Purpose of Luminescence Dating

franz

Franz Hartung is PhD student and research associate at the Cologne Luminescence Laboratory and the project F2 of the CRC 806 “Our way to Europe” and investigates dose rate determination techniques within the context of trapped charge dating methods. Before he came to Cologne, Franz Hartung studied Physics at the TU Dresden and graduated with a diploma degree, whereas the thesis was written in the radiation Physics group (ASP) in the institute of nuclear and particle Physics (IKTP).

Time For Defragmentation. Late Middle Paleolithic Leaf Points in Germany: What was planned and what has been done

banner_buhs_20151207

Bernhard Buhs is a PhD student in the D1 ProjectAnalysis of Migration Processes due to Environmental Conditions between 40.000 and 14.000 a B.P. in the Rhine-Meuse Area.
The Altmuehlian of Southern Germany is a Middle Palaeolithic archaeological industry that contain knapped-stone leaf point artifacts. These industries are commonly dated to the end of the Middle Paleolithic and are regularly invoked in discussions concerning the disappearance of Neanderthals and appearance of Homo sapiens at about 40.000 B.P.

Water resources assessment in arid data-scarce regions – multidisciplinary research in Egypt

banner_CRC_Youssif

Dr. Mohamed Youssif

Arid regions are highly vulnerable with respect to environmental and particularly hydrological changes. Data scarcity for most of these areas (such as Egypt and the most of Middle East) is a great challenge for hydrogeological investigation at practical scales. Moreover, climate change will exacerbate groundwater-related problems by reduction in recharge rates in some areas, increased reliance on groundwater resources due to decrease in the reliability of surface-water sources, saltwater intrusion due to sea-level rise, and deterioration of groundwater quality by increased flushing of urban and agricultural wastes.

Many archaeologists associate the appearance of Homo sapiens and modern behavior with the Middle Stone Age of Africa. Over the years numerous models have been developed to explain how and why modern humans left Africa and dispersed throughout the world. The majority of these models are based on skeletal and genetic data as well as climatic data, while paradoxically very few incorporate archaeological data.

Green Desert – Holocene hydrological changes in the Sahara revealed by lipid biomarker analyses of Lake Yoa (Chad)

Vortrag_Thienemann_banner

11,000 years ago, at the beginning of the Holocene, today’s hyper-arid Sahara desert was dotted with large and small lakes, savannah and grassland and in some regions even humid tropical forest. Due to a strengthened African monsoon triggered by strong orbital forcing i.e. summer insolation, more humid conditions compared to today, prevailed in Northern and Central Africa.
