Extended abstract 1- Introduction Evaluation is a process of assessing the degree of achievement to determined goals. In the meantime, choosing the right method for evaluating the effects will have a significant role on the results and management strategies. Therefore, considering the importance of check dams in watershed management programs in Iran, in this study, performance of check dams i...
The world experience of using electrical exploration methods in the study technogenic bodies is considered, particular: determining zoning tailings, groundwater migration routes and stability dams. ongoing research demonstrates high efficiency combining geophysics, geochemistry, hydrology. On example mining dumps located on territory Kemerovo region Republic Tyva, achievements interdisciplinary...
Waste dumps are widely used to discharge stripped mine wastes in open pit mining methods. As progresses, the height of waste will increase gradually, which may induce sliding failure once exceeds a critical value. Therefore, estimation maximum dumping is crucial life-cycle use dump. However, published information about extremely rare. In this study, estimated based on strength-reduction techniq...
A screening was carried out for CVM, BLAD, DUMPS, bovine citrullinaemia, glycogen storage disease V, and Robertsonian translocations in the cattle population of the Czech Republic. In 406 Holstein sires and 146 Czech Pied (Czech Simmental) sires entering the AI programme in the Czech Republic from 2003–2005, no heterozygous sire for DUMPS, bovine citrullinaemia and BLAD was found. The heterozyg...
