Photosensitized inactivation of microorganisms has been the subject of numerous studies, and various hypothetical reaction mechanisms have been proposed for the interpretation of the phenomenon. In spite of such extensive experimentation and theorizing, there still exists uncertainty concerning the inactivation processes. No at tempt will be made to review the subject since it has been analyzed...

introduction: acute lymphoblastic leukemia (all ) is the most worldwide common type of childhood cancer. methylenetetrahydrofolate reductase (mthfr) and 5-methyltetrahydrofolate-homocysteine methyltransferase (mtr) are crucial enzymes in folate pathways. folate availability is critical factor for dna integrity, required for the transfer of methyl group in the biosynthesis of thymidilate. proced...

shortage of irrigation water, being a crucial problem in arid and semiarid regions, makes it necessary to use treated wastewater in agriculture. a field experiment was conducted to investigate the effect of treated municipal wastewater (tmw) on the yield and fiber quality of cotton (gossypium hirsutum l.) (mehr variety). treated municipal wastewater was supplied from shahrake ghods sewage treat...

introduction atmospheric circulation patterns leads to different weather conditions and rainfall regime change is controlled by seasonal and irregular variations of atmospheric circulation pattern. variety and climate change, such as drought and flood result in changes in the spatio-temporal of precipitation, one of the important parameters conditions mentioned, heterogeneity in moisture transm...

Kinetics of parallel reactions contribute to the elucidation of poly-step mechanisms. Competing pathways in the reaction of benzenediazonium ion with azide anion helped to establish the occurrence of phenylpentazole. Steady state kinetics clarified the competition between the interception of an intermediate and its return to the starting material. The DielsAlder reactions of cyclooctatetraene a...

one of the most important atmospheric systems in the eurasian continent during the northern hemisphere winter season is the siberian high pressure. in this study, using the ncep/ncar reanalysis data for winters of 1948-2008, trend of changes in the intensity of the high system center and its effects on some meteorological fields are investigated. the results show that the 2m height mean tempera...

the civil sanction is one of the most important sanctions for protecting copyright. in french law a special action named counterfeit action is predicted, which not only compensate the damages but also it has a preventive effect. this action doesn't require the proving of the fault and the lawsuit can be done by the author and the person who is awareded the exclusive licence. in this legal ...

the fao penman - monteith (f-p-m) method is now broadly accepted as the standard for estimating the reference evapotranspiration (et0). the method is also now used for evaluating the temperature-based [blaney-criddle (b-c) and hargreaves-samani (h-s)] and radiation-based [jensen-haise (j-h) and turc (tc)] methods. the objective was to compare the et0 estimated by the b-c, h-s, j-h, tc methods w...
