Fragmentation analysis is an essential part of the optimization process in any mining operation. The costs loading, hauling, and crushing rock are strongly influenced by size distribution blasted rock. Several direct indirect methods used to analyse or predict fragmentation, but none entirely applicable fragmentation assessment sublevel caving mines, mainly because limitations imposed undergrou...

In the whole embryo, O6-alkylguanine-DNA alkyltransferase (AT) activity increased until day 9 of development and declined sharply after day 13. AT activity of the liver was greatest between day 12 and day 20 and decreased fast after hatching. In the brain, AT activities reached a maximum at day 17 and 18 and declined sharply after hatching. At two developmental stages with different AT activiti...

A measurement of the splitting function in pp and PbPb collisions at a center of mass energy of 5.02 TeV per nucleon pair is presented. The virtuality evolution of partons traversing the hot QCD medium created in a heavy ion collision is potentially modified due to interactions with the color charges of the medium. This measurement probes this phenomenon by measuring the generalized fragmentati...

The first probe of the correlation of the T-odd one-particle fragmentation function responsible for the left–right asymmetry of fragmentation of a transversely polarized quark is done by using the 1991-95 DELPHI data for Z → 2-jet decay. Integrated over the fraction of longitudinal and transversal momenta, this correlation is of 1.5% order, which means order of 13% for the analyzing power. A ra...

We analyse recent data on the production of forward neutrons in deep inelas-tic scattering at HERA in the framework of a perturbative QCD description for semi-inclusive processes, which includes fracture functions. Using a model estimate for the non-perturbative piece of the fragmentation process, in fairly good agreement with the available data, we analyse the Q 2 dependence of the resulting f...

conclusions in our study, no prominent effect was seen; therefore, in order to have a better perspective of crocin activity against cancerous cell lines, further studies are highly recommended. results the highest concentration of crocin significantly decreased ros production after 48 hours of treatment. however, crocin had no effect on the expression level of hsp (heat shock protein). addition...

SLEEP-DISORDERED BREATHING (SDB) IS A FREQUENT CONDITION THAT AFFECTS BOTH CHILDREN AND ADULTS1-4 AND IS ASSOCIATED WITH DISRUPTION OF ALVEOLAR VENTILATION, HYPOXEMIA, AND SLEEP FRAGMENTATION. Sleep fragmentation in healthy adults, ie, the presence of multiple respiratoryrelated arousals during sleep, correlates with neurobehavioral performance decrements the following day.5-7 In contrast, desp...
