Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. In this study the antioxidant activity and radical scavenging activity of methanolic extracts of s...

the individual effects of cadmium concentrations (0, 0.005, 0.05and 0.5 mg. l-1) on the growth(cell number and chlorophyll content) and beta-carotene synthesis of two strains (iranian and australian) ofgreen algae d.salina have been studied for a duration of 36 days. the effects of these cadmiumconcentrations on the amount of cell magnesium and calcium have also been evaluated. an increase inca...

polymerization of styrene in presence of two monofunctional initiators is studied kinetically in an ampoule scale. polymerizations were ceased at different conversions for each ampoule while the temperature was increased almost linearly during the reaction. three different initiator mixtures were used. the first mixtures were composed of benzoil peroxide (bpo) and t-butyl perbenzoate (tbpb) wit...
