1. The thyroid exerts a retarding action on the carbohydrate destroying mechanism of the body. 2. This retarding action is not changed when the gland is boiled, showing that it is not a ferment action. 3. Iodothyrin, the active principle of the gland, exerts this retarding influence more markedly even than the whole thyroid. 4. This antagonism between the thyroid and the carbohydrate destroying...

This article addresses the interplay between heat of hydration and physico-mechanical properties of calcium sulfate hemi-hydrate in the presence of retarding additives such as citric and malic acids and sodium citrate. The heat of hydration was measured using a semi-isothermal calorimeter. Results proved that citric and malic acids had superior impact on hydration and mechanical properties. Whi...

Our research on learning enhancement has been focusing on the consequences for learning and forgetting of some of the more obvious and concrete choices that arise in instruction, including: How does spacing of practice affect retention of information over significant retention intervals (up to two years)? Do spacing effects generalize beyond recall of verbal materials? Is feedback needed to pro...

the aim of this study is extraction of phenolic compounds from walnut leaves of touyserkani variety with two extraction methods (traditional method and with microwave assisted extraction (mae)) and evaluation of their antioxidant activity. total phenolic contents and antioxidant properties of aqueous, methanol (80%) and ethanol (50%) extracts in different times was determined. at the next stage...
