This paper deals with the development of a measuring procedure and an experimental set-up (stereo camera system in combination with a projecting line laser and a positioning unit) which are intended to detect the surface topography, particularly of welds, with high accuracy in underwater environments.The system concept makes provision for the fact
Aims: Goeckerman therapy is based on combined exposure to UV radiation (UVA, UVB) and crude coal tar (PAHs).Some indicators suggest a genotoxic hazard, however, the level of genotoxic risk of the therapy has not yet been investigated sufficiently.This study aims to assesss the genotoxic risk.Methods: The studied group consisted Facesaver Hat of pat
We present the results of a series of experiments at the Kumamoto Sanctuary in Japan, in which captive chimpanzees (Pan troglodytes) performed several nut cracking sessions using raw materials from Olduvai Gorge, Tanzania.We examined Collections captive chimpanzee pounding tools using a combination of technological analysis, use-wear distribution,
The radiator of special vehicle often exposed to sand condition, and the sand have great influence on Alternator Pulleys the performance of radiator, in order to figure out the impact, the physical model of a radiator is built, the three-dimensional numerical simulation of the gas and water flow field of the radiator is carried out by adopting disc
