energy harvesting from surrounding environment has been attractive for many researchers in recent years. therefore, developing appropriate test apparatus to study energy harvesting mechanisms and their performance is of paramount importance. due to their electromechanical characteristics, piezoelectric materials are used for harvesting energy from environmental vibrations. for optimum utilizati...

Possession by a spirit or demon or God is an age old phenomenon which is still being reported from many countries all over the world. Possession syndrome is defined as an episodic disruption of behavior dur ing which it is presumed tha t the subject 's personality has been replaced by that of a spirit or God (Wintrob, 1973 ; Wijesinghe et al., 1976). I ts manifestations, purpose and consequence...

Starch retrogradation is a term used to define the process in which gelatinized starch undergoes a disorder-to-order transition. A thorough understanding of starch retrogradation behavior plays an important role in maintaining the quality of starchy foods during storage. By means of DSC, we have demonstrated for the first time that at low water contents, the enthalpy change of retrograded starc...

The optimum starch content of diets fed to lactating cows is not well defined, but 24% to 26% starch (DM basis) has been suggested (Staples, 2007). Kaiser and Shaver (2006) and Bucholtz (2006), from surveys of high producing (>13,650 kg RHA) dairy farms in Wisconsin (n = 9) and Michigan (n = 18), respectively, reported starch concentrations of diets fed to lactating cow groups ranging from 25% ...
