lamerin microspridia (lbms) isolated from lamerin breed of the silkworm, bombyx mori, l. and the standard strain nosema bombycis, were induced to germinate artificially by two-step procedure. fresh percoll purified spores were activated by incubating them in potassium hydroxide solution (koh) (ph 11.00) and germinated artificially by using phosphate buffer saline (pbs), (ph 7.00). germinated sp...

this paper analyzes renewal input state dependent queue with $n$- policy wherein the server takes exactly one vacation. using the supplementary variable technique and recursive method, we derive the steady state system length distributions at various epochs. various performance measures has been presented. finally, some numerical  computations in the form of graphs are presented to show the par...

Upper thermal limits vary less than lower limits among related species of terrestrial ectotherms. This pattern may reflect weak or uniform selection on upper limits, or alternatively tight evolutionary constraints. We investigated this issue in 94 Drosophila species from diverse climates and reared in a common environment to control for plastic effects that may confound species comparisons. We ...

The hypothesis that a mixture of two ampholytes behaves, within certain limits, as an individual (1) with characteristics distinct from either component can also be semiquantitatively tested by certain conductivity experiments. These are based on the observation that the addition of such a substance as gelatin markedly decreases the observed conductivity of a phosphate solution. The magnitude o...

A new method for the simultaneous determination of tin, lead, cadmium, and mercury in tobacco and tobacco additive by reversed-phase high-performance liquid chromatography combined with microwave digestion and an online enrichment technique is developed. The tin, lead, cadmium, and mercury ions are precolumn derivatized with tetra-(4-dimethylaminophenyl)-porphyrin (T(4)-DMAPP) to form color che...

With the increasing uniprocessor and SMP computation power available today, interprocessor communication has become an important factor that limits the performance of cluster of workstations. Many factors including communication hardware overhead, communication software overhead, and the user environment overhead (multithreading, multiuser) affect the performance of the communication subsystems...

the present study is aimed at the overall improvement in the efficacy, reduced toxicity and enhancement of therapeutic index of cisplatin. nanocapsules of cisplatin containing ethylcellulose have been prepared using solvent evaporation technique under ambient conditions. the prepared nanocapsules were used for controlled drug release of anticancer agents with gold and iron oxide nanoparticles. ...

liver injury induced by viruses, chemicals and drugs can be protected by different medicinal plants. feijoa sellowiana (myrtaceae) is an evergreen bush native to southern areas of south america, as well as iran where the fruits are very popular. feijoa has shown a potent antimicrobial effect. morever, the antioxidant activity of total feijoa extract has also been reported. mdma or ecstasy is a ...

Liquid chromatography-mass spectrometry (LC-MS, or alternatively HPLC-MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry. LCMS is frequently used in drug development at many different stages including Peptide Mapping, Glycoprotein Mapping, Natural Products Derepli...
