Geothermal energy can be useful after extraction from geothermal wells, borehole heat exchangers and/or natural sources. Types of boreholes are wells (for water production and injection) exchange with the ground without mass transfer). The purpose is to harvest present in aquifer. They often involve a pumping chamber. injection used for injecting back produced into aquifer, having harvested con...

Longwall shearers operating in the underground mine workings move along longwall face conveyor troughs. The haulage system, which is made up of two kinematic pairs form track wheels installed shearer movers, cooperating with toothed route built conveyor’s throughs, responsible for moving shearer. currently used solutions shearers’ systems do not ensure proper cooperation segments, results failu...

Earlier methods adopted for the estimation of median lethal dose (LD50) used many animals (40 – 100). But for the up – and – down procedure, 5 – 15 animals can be used, the number I still consider high. So this paper seeks to adopt arithmetic, geometric and harmonic (AGH) mean for rough estimation of median lethal dose (LD50) using up – and – down procedure by using 2 – 6 animals that may likel...

User’s choices of conical picks currently involve specifying their material and geometric parameters (functional requirements), incorporating the place conditions work (operational requirements). The selection is usually made based on solely one criterion, which price. Thus, at stage both purchase operation, quality picks, as well matching for a specific machine, are not assessed. problem defin...
