Stockpiling and blending play a major role in maintaining the quantity and quality of the raw materials fed into processing plants, especially the cement, iron ore and steel making, and coal-fired power generation industries that usually require a much uniformed feed. Due to the variable nature of such materials, they even come from the same source and the produced ores or concentrates are seld...

The dump, with the compact rock platform and high steep loose slope that is formed during coal mining, most serious area of soil erosion in a surface mine. Ground fissures are typical geological hazard mining areas. However, effect ground on remains unclear. Rainfall experiments were conducted to determine varying characteristics wetting front, runoff sediment production, denudation rate, as we...

In this article, enhancement of THz radiation was studied using pulse shaping thchnique. Over 40% enhance was demonstrated by positive chirped optical pulses. This could be attributed to the pump-dump process in excitation.

We have studied the features of heavy metal accumulation in and have carried out a hygienic assessment of medicinal plants Taraxacum officinale Web. growing in various areas of the microrelief of the Kedrovskii coal mine rock dump. We have revealed a higher variability in the content of Cr, Mn, Zn and Fe mobile forms in the waste embryonic soils and have found that Cu and Zn content was lower t...

While a core dump carries a large amount of information, it barely serves as informative debugging aids in locating software faults because it carries information that indicates only a partial chronology of how program reached a crash site. Recently, this situation has been significantly improved. With the emergence of hardwareassisted processor tracing, software developers and security analyst...

Thymidylate synthase (TS), a half-the-sites reactive enzyme, catalyzes the final step in the de novo biosynthesis of deoxythymidine monophosphate, dTMP, required for DNA replication. The cocrystal structure of TS from Pneumocystis carinii (PcTS), a new drug target for an important pathogen, with its substrate, deoxyuridine monophosphate (dUMP), and a cofactor mimic, CB3717, was determined. The ...
