We have found that elevated copper concentrations, apart from the inhibition of oxygen evolution, changed the initial states distribution of the oxygen-evolving complex. Already at low concentrations, copper ions oxidized the low-potential form of cytochrome b (559) and also its high-potential form at higher concentrations at which fluorescence quenching was observed. We suggest that the primar...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

BACKGROUND Revised National TB Control Programme (RNTCP), Andhra Pradesh, India. There is limited information on whether MDR-TB suspects are identified, undergo diagnostic assessment and are initiated on treatment according to the programme guidelines. OBJECTIVES To assess i) using the programme definition, the number and proportion of MDR-TB suspects in a large cohort of TB patients on first...
We investigate large sieve inequalities such as 1 m m X j=1 log P e j C 2 Z 2 0 log e P e d ; where is convex and increasing, P is a polynomial or an exponential of a potential, and the constant C depends on the degree of P , and the distribution of the points 0 1 < 2 < < m 2 . The method allows greater generality and is in some ways simpler than earlier ones. We apply our results to estimate t...
