The penetration of sparfloxacin into human neutrophils (PMN) and different tissue culture cells (HEp-2 and McCoy) was evaluated. The cellular to extracellular concentration ratios (C/E) of sparfloxacin were always higher than 4 at extracellular concentrations ranging from 0.5 to…
The fisheries sector is currently contending with the hectic development of its own political economy framework being convulsed by the dynamics of decentralisation. This process is enshrouded in an environment of economic globalisation, taking place against the backdrop of the…

Se obtuvo dióxido de titanio por medio de una nueva ruta de síntesis que combina la técnica solgel con reacción a presión autógena. Se ensayaron dos geles de síntesis con diferentes fuentes de titanio; una de ellas usó tetraisopropil ortotitanato empleando agua e isopropanol…
We present a translation of problems of Formal Context Analysis into ideals problems in F2[x] through the Boolean derivatives. The Boolean derivatives are introduced as a kind of operators on propositional formulas which provide a complete calculus. They are useful to refine…
