the aim of this trial was to determine the toxic effect of oms-43 on spraymen and inhabitants. the spraying operation lasted for 30 successive days, and two teams consisting of 20 spraymen, 2 mixers, 4 foremen and team leaders were engaged in this operation. the operators were under systematic and closed clinical observation and cholinesterase determination (tintometric method) during the opera...

This paper presents a mathematical model that could assist in measuring, monitoring and controlling tem-perature variation in cold and ‘red-hot’ metal working conditions of machining. A numerical analysis tech-nique of the temperature distribution, based on the theory of complex applied potential, was carried out using the principles of relationship analysis between the paths of heat supply in ...

This paper deals with the issue of dynamic effects a high-speed railway vehicle on track. Some aspects vehicle/track interaction at higher speeds are described. In this context, multi-body model was created and several simulation scenarios were performed model. Furthermore, simulations evaluated focus selected characteristics interaction.

For the zones of “risky farming” characteristic Far East Russian Federation, natural production conditions region are an important problem in preparing soil for further basic agricultural work. So, when carrying out early spring work, due to presence a solid underlying layer form permafrost, they shall be completed operational terms no more than 10 days, until permafrost base thaws and has not ...
