A cosmogenic nuclide-derived chronology of pre-Last Glacial Cycle glaciations during MIS 8 and MIS 6 in northern Patagonia

Autor: T. P. M. Leger, A. S. Hein, Á. Rodés, R. G. Bingham, I. Schimmelpfennig, D. Fabel, P. Tapia

Publikováno v: Climate of the Past, Vol 19, Pp 35-59 (2023)

The precise environmental mechanisms controlling Quaternary glacial cycles remain ambiguous. To address this problem, it is critical to better comprehend the drivers of spatio-temporal variability in ice-sheet evolution by establishing reliable chron

Concentrations of 9-Tetrahydrocannabinol and 11-Nor-9-Carboxytetrahydrocannabinol in Blood and Urine After Passive Exposure to Cannabis Smoke in a Coffee Shop

Autor: Jürgen Prof. Dr. Becker, R. Urban, T. Kaufmann, V Kuntz, J. Röhrich, I Schimmel, S Drobnik, S. Zörntlein

Publikováno v: Journal of Analytical Toxicology. 34:196-203

Cannabinoid concentrations in blood and urine after passive exposure to cannabis smoke under real-life conditions were investigated in this study. Eight healthy volunteers were exposed to cannabis smoke for 3 h in a well-attended coffee shop in Maast

Long Term Toxicological Studies on the Progestin STS 557

Publikováno v: Experimental and Clinical Endocrinology & Diabetes. 81:179-196

The toxicity of 17 alpha-cyanomethyl-17 beta-hydroxy-estra-4, 9-dien-3-one (STS 557) was studied by its oral administration of 0.1, 1.0 or 10.0 mg/kg/day to Wistar rats for six months, and of 0.01, 0.1 or 1.0 mg/kg/day to beagle dogs for six months,

In-phase millennial-scale glacier changes in the tropics and North Atlantic regions during the Holocene

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-11 (2022)

Glaciers showed a similar evolution in Greenland, Europe, the US and the tropical Andes during the Holocene. The authors propose the Atlantic Meridional Ocean Overturning Circulation as a key driver of this trend.

Glacier response to Holocene warmth inferred from in situ 10Be and 14C bedrock analyses in Steingletscher's forefield (central Swiss Alps)

Autor: I. Schimmelpfennig, J. M. Schaefer, J. Lamp, V. Godard, R. Schwartz, E. Bard, T. Tuna, N. Akçar, C. Schlüchter, S. Zimmerman

Publikováno v: Climate of the Past, Vol 18, Pp 23-44 (2022)

Mid-latitude mountain glaciers are sensitive to local summer temperature changes. Chronologies of past glacier fluctuations based on the investigation of glacial landforms therefore allow for a better understanding of natural climate variability at l

Anodic electrosynthesis of Cu2S and CuInS2 films

Autor: Mareen I Schimmel, Krishnan Rajeshwar, Norma R. de Tacconi

Publikováno v: Journal of Electroanalytical Chemistry. 453:187-195

This paper describes the combined use of voltammetry and electrode illumination during the anodic growth of Cu2S and CuInS2 films on copper substrates in sulfide containing KOH medium. The importance of compound stoichiometry in the two systems on th

Dehalogenation of pyrolysis products

Publikováno v: Journal of Analytical and Applied Pyrolysis. 30:35-46

During pyrolysis of chlorine-containing materials, it is necessary to trap the HCl formed to avoid re-formation of organochlorine compounds and to prevent corrosion in the plant. This is usually done using limestone, but the resulting mass streams ca

Publikováno v: International Journal of Anthropology. 8:105-110

Haptoglobin (HP), transferrin (TF), group specific component (GC) and protease inhibitor (PI) polymorphisms were studied in three population samples from Thuringia: Jena, n=204; Erfurt, n=213; Suhl, n=180. GC and in particular TF allele frequencies s
