The macroscopic character of the leaves, physical constant values, extractive values, behavior on treatment with different chemical reagents. Fluorescence characters under ultraviolet light after treatment wit different chemical reagents of the powdered leaves of Cassia tora Linn. (Family: Leguminosae) were studied to characterize some pharmacognostical parameters. Preliminary phytochemical stu...

the aim of the present study was to characterize allergen-specific immunoglobulin e (ige) among children in fez region. eighty one children were recruited from the hospital university center of fez. all of them had completed a questionnaire before taking sera. the sera were used to measure total ige and specific data to proteins of egg's white (ewp), peanuts (pp) and gliadins (g). in last part,...

titanium dioxide nanocrystals were synthesized by sol-gel method at room temperature. titanium isoprophoxide and absolute ethanol were used as precursors to prepare the sol. the ph of the solution was adjusted by adding nitric acid and sodium hydroxide solution. the prepared tio2 nanocrystals were annealed at 325°c, 425°c and 525°c respectively. the effect of ph on the surface morphology and st...

india is one of the largest producers of onion in the world producing over 13,920,000 metric tons. storage is a major problem which leads to spoilage, and microbes play an important role in the spoilage. in this present study, biotechnologically important strains have been isolated from the spoiled onions by using appropriate enriched media. two potential strains were isolated and a brief compa...

among the environmental problems in nigeria is the lack of proper management of municipal solid wastes (msw), which is capable of releasing hazardous chemicals via leachate to the surrounding environment. in this study, the potential toxic effects of raw leachate obtained from aba-eku landfill (aerl) on clarias gariepinus; and the microorganisms that may be present in the leachate were investig...

dosulepin and doxepin are tricyclic antidepressants. the molecular geometries, harmonic vibrational frequencies, quantum chemical parameters and thermodynamic properties of dosulepin and doxepin were calculated by generalized gradient approximation methods developed by perdew and wang (gga-pw91) and becke-lee-yang-parr (gga-blyp) in the gas phase and solution media. the local reactivity of thes...

We present Nt = 4 lattice results for the equation of state of 2 + 1 flavour staggered, dynamical QCD at finite temperature and chemical potential. We use the overlap improving multi-parameter reweighting technique to extend the equation of state for non-vanishing chemical potentials. The results are obtained along the line of constant physics. Our physical parameters extend in temperature and ...

We present experimental results on the propagation of an ultrasonic wave (40 kHz) in liquid foams, as a function of the foam physical and chemical parameters. We have first implemented an original setup, using transducers in a transmission configuration. The foam coarsening was used to vary the bubble size (remaining in the submillimeter range), and we have made foams with various chemical form...
