Novel conjugates of the antimalarial drug primaquine (compound 1) with ferrocene, named primacenes, have been synthesized and screened for their activities against blood stage and liver stage malaria in vitro and host-vector transmission in vivo. Both transmission-blocking and blood-schizontocidal activities of the parent drug were conserved only in primacenes bearing a basic aliphatic amine gr...
نتایج تحقیق نشان داد که مکمل های ردبول ومگابیسیک تغییرات معنی داری در توان اوج، توان حداقل، توان میانگین ورزشکاران پسرایجاد نکرده اند ولی گروهی که مکمل ردبول مصرف کرده بودندبه میزان 85/2 درصد تعداد گلبول های سفید خون آزمودنی هاپس از آرمون اول ودوم افزایش یافت وگروهی که مکمل مگابیسک دریافت کرده بودند به میزان 83/3 درصد تعداد مونوسیت وبه میزان22/ 9 درصد تعداد لنفوسیت آزمودنی ها پس از آرمون اول ود...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
abstract: â in this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13x zeolite in a fixed-bed adsorption tower which is used to capture co2 from both humid and dry nitrogen stream under industrial conditions. the results show that the performance of amine-grafted adsorbent and 13x zeolite is almost the same in the dry ...
today power consumption is considered to be one of the important issues. therefore, its reduction plays a considerable role in developing systems. previous studies have shown that approximately 50% of total power consumption is used in cache memories. there is a direct relationship between power consumption and replacement quantity made in cache. the less the number of replacements is, the less...
In a motor with a liquid hydrocarbon fuel, the hydrocarbon fuel diffuses into the amine fuel and the fuel concentration changes with time. Therefore, the variation of amine fuel at each time should be predicted to ensure the safe start of the motor and the fuel storage should be recharged if the amine fuel concentration is out of specific range. In this work, the amount of hydrocarbon fuel diff...
Abstract The substituted aromatic amine o -toluidine (2-methylaniline, 1-amino-2-methylbenzene) is frequently encountered in electrochemical research as a soluble corrosion inhibitor dissolved aqueous media used e.g., cooling systems, homomonomer for formation of intrinsically conducting poly- and comonomer respective copolymers their composites. obtained polymers are suggested protection coati...

A more sustainable and efficient protocol for the photocatalytic α-amino arylation promoted by fac-Ir(ppy)3 was developed. Three noteworthy results were achieved: i) replacement of toxic medium DMA with greener solvents NBP NHP, concurrent improvement process efficiency lowering both amine base amount; ii) development a recycling solvent NHP commercially available costly photocatalyst fac-Ir(pp...
