Adam-Gibbs Formulation of Enthalpy Relaxation Near the Glass Transition
The entropically based nonlinear Adam-Gibbs equation is discussed in the context of phenomenologies for nonlinear enthalpy relaxation within the glass transition temperature range. In many materials for which adequate data are available, the nonlinear Adam-Gibbs parameters are physically reasonable and agree with those obtained from linear relaxation data and thermodynamic extrapolations. Obser...

A need for better vitamin nutrition appears at three levels: vitamin insufficiency, deficiency, and dependence. A vitamin insufficiency requires the body to make some degree of metabolic adjustment because the amount of the coenzyme (vitamin) is limited. Myofascial pain syndromes are aggravated by insufficient levels of at least four Bcomplex vitamins as listed above. Vitamin deficiency, on the...
متن کاملIan Donald (1910?1987)

During the early 1900s, physicians had no way to see inside a woman?s uterus [5] during pregnancy [6]. Donald developed the first method of scanning human internal anato...
