aquatic plants have been used prevalently in china since 3000 years ago due to having various chemical compounds for diseases prevention and cure. dunaliella salina is one of the micro algae in marine ecosystems containing beta-carotene, retinal, apocarotenoides, ketones, aldehydes and epoxides which enable it to absorb free radicals and produce singlet oxygen.  in many studies, the anti-cancer...

This study is concerned with the numerical analysis, formulation, programming and computation of steady, 3D conservation equations of reacting laminar flow heat and mass transfer in ducts of arbitrary cross-sections. The non-orthogonal boundary-fitted coordinate transformation method is applied to the Cartesian form of overall-continuity, momenta, energy and species-continuity equations, parabo...

background: the aim of this study was to characterize the leishmania parasites isolated from cuta­neous leishmaniasis (cl) patients in fars province in iran and to compare the potential infectivity of the isolates in macrophage cell line. moreover, attempt was made to find out the association between parasite infectivity and their zymodems. methods: twenty samples were taken from the skin lesio...

conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...

liquid-liquid equilibrium data for the (water + lactic acid + 2-ethy-1-hexanol) ternary system in t=298.2k and p=1atm were determined and tie- lines related to equilibrium data has been drawn in the phases diagram . the reliability of the experimental tie-line data for this system was as confirmed by using the hand and othmer –tobias correlations. the tie-line data were correlated by means of t...
