seaweeds are the novel bioactive compounds resources with antioxidant activity. the aim of this study was to evaluate the efficacy of microwave radiation on antioxidant compounds extracted from red algae hypneahamulosa and optimal extraction conditions using response surface methodology (rsm).. independent variables were time (4,8,12 min), acetone/water concentration (50%,75% ,100% acetone) and...

We studied the kinetics of the reaction between cholesterol and sulfuric acid in acetic acid-acetic anhydride medium. Results have been used to establish near-optimal conditions for the fast kinetic determination of cholesterol in serum. The reaction rate measured during the first 20 s of the reaction is proportional to cholesterol concentration. There is good agreement (<2% deviation) between ...

In the current investigation, evaporation and transpiration potential were also estimated by means of FAO Penman- Monteith evapotranspiration estimation method and Deviation from Optimum Percentage (DOP) technique by climatic elements (min-max temperature, relative humidity, wind speed and radiation) during at least 10 years statistical period regarding sunflower phenological conditions in Kurd...

the purpose of this paper is a study on the effect of cash flows on the gap between actual and optimal financial leverage ratio companies listed in tehran stock exchange. in this regard, we try to help with advanced econometric techniques such as partial adjustment model on panel data and generalized method of moments to achieve a reasonable estimate of the impacts.in this paper, were analyzed ...
