In this study, the regional health loss due to the air pollution of a coal-fired power plant is analyzed by using the atmospheric dispersion model.AERMOD was used to simulate the increment concentration map of point source emission, and the GIS geographic information system was used to displace the distribution of air pollution concentration and re
Abstract Background Porcine teschovirus (PTV) circulates among wild and domesticated pig populations without causing clinical disease, however neuroinvasive strains have caused high morbidity and mortality in the past.In recent years, several reports appeared with viral agents as a cause for neurologic signs in weanling and growing pigs among which
This research presents the theoretical model, simulation and experimental verification of the maximum stepover estimation for different cases on the machine surface profile using the end-filleted cutter in multi-axis machining.Where in this research, the equations that detect the maximum stepover at allowable scallop height value have been taking i
Pitchers Abstract Question classification is an essential task in question answering (QA) systems.An effective and efficient question classification model can not only restrict the search space for answers, but also guide the QA system in selecting the optimal knowledge base and search strategy.In recent years, self-attention mechanism has been wid
This 74-in-diameter blower had an overhung rotor design of titanium construction, operating at 50 pounds per square inch Fridge Globe gauge in a critical chemical plant process.The shaft was supported by oil-film bearings and was directdriven by a 3000-hp electric motor through a Round Cocktail Table metal disk type of coupling.The operating speed
