In this work, the rise characteristics of a single H2 bubble, in ellipsoidal regime, (i) water, (ii) electrolyte (2 M, 4.5 M NaCl) solution and (iii) various concentrations mixture (up to 6.4 1:5 weight fraction NaCl-NaClO3), have been studied, at temperatures up 80°C. Our results show that both individual collective effects temperature concentration on velocity bubble shape are purely dependen...

The generally accepted view that rates of oxygen consumption of tissues and poikilotherms increase regularly with rising temperature was subjected to careful examination using brain slices and skin of rats and nine different species of aquatic and terrestrial animals. It was found that, although there are statements in the literature to the contrary, the influence of temperature is a regular on...

Rook theory has been investigated by many people since its introduction by Kaplansky and Riordan in 1946. Goldman, Joichi and White in 1975 showed that the sum over k of the product of the (n− k)-th rook numbers multiplied by the k-th falling factorial polynomials factorize into a product. In the sequel, different types of generalizations and analogues of this product formula have been derived ...
