W artykule przedstawiono informację na temat zmian górniczego wyciągu szybowego w przedziale klatkowym szybu „Sobieski III” Tauron Wydobycie S.A. Z.G. Sobieski. W układzie wzbudzenia silnika napędowego oraz prądnic sterujących zainstalowano wyodrębniony zespół sterowniczy oparty na przekształtnikach tyrystorowych MENTOR, co pozwoliło zastąpić układy kłopotliwe w eksploatacji, m.in. wzmacniacz elektromaszynowy...
The article presents information on changes to the mine shaft hoist in the cage compartment of the “Sobieski III” shaft of Tauron Wydobycie S.A. A separate control unit based on MENTOR thyristor converters was installed in the excitation system of the drive motor and control generators, which allowed the replacement of systems that were difficult to operate, e.g. electromechanical amplifier (amplidyne)...
Genetic factors are important in the pathogenesis of osteoporosis, but little is known about the genetic determinants of treatment response. Previous studies have shown that polymorphisms of the LRP5 gene are associated with bone mineral density (BMD), but the relationship between LRP5 polymorphisms and response to bisphosphonate treatment in osteoporosis has not been studied. In this study we investigated...
The TGFB1 gene which encodes transforming growth factor beta 1, is a strong candidate for susceptibility to osteoporosis and several studies have reported associations between bone mineral density (BMD), osteoporotic fractures and polymorphisms of TGFB1, although these studies have yielded conflicting results.We investigated associations between TGFB1 polymorphisms and BMD and fracture in the GENOMOS...
