Summary: Purpose: Although memory, language, and executive functions have been extensively studied in patients with mesial temporal lobe epilepsy (MTLE), investigations into advanced social cognitive abilities neglected. In the present study, we investigated ability to detect faux pas possible mediating clinical demographic variables MTLE compared an not originating within healthy controls. Methods: The 27 (16 were pre‐ 11 postoperatively), extramesiotemporal (except frontal epilepsy), 12...
Abstract This paper reviews major findings of the Multidisciplinary Experimental and Modeling Impact Crater Research Network ( MEMIN ). is a consortium, funded from 2009 till 2017 by German Foundation, aimed at investigating impact cratering processes experimental modeling approaches. The vision this network has been to comprehensively quantify conducting strictly controlled campaign laboratory scale, together with multidisciplinary analytical approach. Central use powerful two‐stage...
Abstract Two impact cratering experiments on nonporous rock targets were carried out to determine the influence of target composition structural mechanisms subsurface deformation. Projectiles 2.5 mm diameter accelerated ~5 km s −1 and impacted onto blocks marble or quartzite. Subsurface deformation was mapped analyzed microscale using thin sections bisected craters. Additionally, both modeled calculated strain zones underneath craters compared experimental features. Microanalysis shows that...
Abstract Many siliciclastic reservoirs contain millimetre-scale diagenetic and structural phenomena affecting fluid flow. We identified three major types of small-scale flow barriers in a clastic Rotliegend hydrocarbon reservoir: cataclastic deformation bands; dissolution seams; bedding-parallel cementation. Deformation bands various orientations were analysed on resistivity image logs core material. They are mainly conjugates, can be used to validate seismically observable faults infer...
Abstract Hypervelocity impact experiments on porous tuff targets were carried out to determine the effect of porosity deformation mechanisms in crater's subsurface. Blocks Weibern Tuff with about 43% impacted by 2.5 mm and 12.0 diameter steel spheres velocities between 4.8 km s −1 5.6 . The postimpact subsurface damage was quantified computer tomography as well meso‐ microscale analyses bisected crater intensity style mineral clasts matrix mapped their decay depth determined. Subsurface...
Abstract In abrupt and extreme loading events, such as meteorite impact or explosions, minerals undergo unique crystallographic changes known shock metamorphism. The discovery of terrestrial craters relies on the unequivocal documentation effects. While effects for most rock-forming silicates have been intensely studied calibrated experimentally against pressure, unambiguous calcite, one abundant in Earth's upper continental crust, are rare. Here, we examined potential high twin densities a...
Abstract Annually about 5.7 million tons of waste incinerator ash accumulate in Germany through the incineration municipal waste. The new method electrodynamic fragmentation allows ashes with complex material compositions to be broken at interfaces and then sorted into materially pure components. aim current ASHCON research project is substitute natural aggregate grain fraction 2/8 mm conventional formulations for ready‐mixed concrete blocks by these secondary raw materials order keep them...
