The toxicity of whole, saturate, and aromatic hydrocarbon mixtures from flare pit and crude oil sources were evaluated using Lumbricus terrestris.Body burden analysis was used to analyze the intrinsic toxicity of the decada tequila six hydrocarbon mixtures.The major fractions of the whole mixtures, the saturate, and aromatic fractions had different
The relevance of the research.One of the main technological parameters of the pellet impact drilling is the spacing between a drill bitand a holebottom.There are several methods and constructions of drill bits that allow keeping this distance with bit feet.In this case, the jet apparatus is held at a certain distance from the blades, which destroy
The purpose of the present study was to investigate the intra- and inter-individual variability in arm-leg coordination during the underwater phase of the turn segment in 200 m breaststroke.Thirteen male swimmers were recruited and performed a 200 m breaststroke in a pre-calibrated 25 m pool.Sub-phases during the underwater segment were obtained us
A 2.5-dimensional climate model of intermediate complexity, CLIMBER-2, fully coupled with the GREMLINS 3-D thermo-mechanical ice sheet model is used to simulate the evolution of major Northern Hemisphere ice sheets during the oswald the octopus stuffed animal last glacial-interglacial cycle and to investigate the ice sheets responses to both insola
The aim of this study was to estimate the development of fertility in North-Central Namibia, former Ovamboland, from 1960 to 2001.Special attention was given to the onset of fertility decline and to the impact of the HIV epidemic on fertility.An additional aim was to introduce parish registers as a source of data for fertility research in Africa.Da
