Relative Shock Effects in Mixed Powders of Calcite, Gypsum, and Quartz: a Calibration Scheme from Shock
Introduction: The shock behavior of calcite and gyp-sum is important in understanding the Cretaceous/Tertiary event and other terrestrial impacts that contain evaporite sediments in their targets. Most interest focuses on issues of devolatilization to quantify the production of CO 2 or SO 2 to better understand their role in generating a temporary atmosphere and its effects on climate and biota...
متن کاملDeveloping a Shock-Capturing Formulation with Higher Performance to Capture Normal Standing Shock in All-Speed Regime
The main objective of the present study is to utilize a novel linearization strategy to linearize the convection terms of the quasi-one-dimensional Euler governing equations on collocated grids and to examine its shock-capturing capabilities. To avoid a pressure checkerboard problem on the collocated grids, it is necessary to utilize two velocity definitions at each cell face. Similarly, we def...
متن کاملSHOCK INDUCED VAPORIZATION OF ANHYDRITE CaS04 AND CALCITE CaCO3
Discovery of abundant anhydrite (CaS04) and gypsum (CaS0+2HzO) in the otherwise carbonate sediments comprising the upper portion of the rocks contained within the Chicxulub impact crater has prompted research on the shock-induced vaporization of these minerals. We use a vaporization criterion determined by shock-induced entropy. We reanalyze the shock wave experiments of Yang [ 11. He shocked 3...

متن کاملImpact of heat shock step on bacterial transformation efficiency
CaCl2 treatment followed by heat shock is the most common method for artificial transformation. Here, the cells were transformed using CaCl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. The BL21 strain of Escherichia coli (E. coli) was being susceptible using CaCl2 treatment. Some Cells were ...
