A sequential implicit numerical scheme is proposed for a system of partial differential equations defining the transport of heat and mass in the channel flow of a variable-viscosity fluid. By adopting the backward difference scheme for time derivative and the central difference scheme for the spatial derivatives, an implicit finite difference scheme is formulated. The variable-coefficient diffu...

Experiments are presented in which a random dot pattern moved vertically upwards (velocity vector V(1)) and then abruptly changed its direction of motion by the angle alpha (velocity vector V(2)), either to the left or to the right, without changing the speed. Subjects performed simple reactions to the direction change, disregarding its sign. In another experiment choice reactions to the same s...

THE significant decline in the income velocity of money during 1982 and in the first quarter of 1983 has engendered confusion and controversy.’ Amid this controversy, little attention has been paid to the more fundamental role velocity plays in macroeconomics and, hence, about its potential and actual importance in the conduct of monetary policy. This article sets forth the concept of income ve...

Atmospheric reaeration process plays a key role in degradation of organic matter and self-purification processes affecting dissolved oxygen (DO) concentrations rivers streams. Moreover, water quality (WQ) can be highly dependent on flow velocity conditions. Where, rates are positively correlated with high velocity. Therefore, the present work reports deep insights concentration DO biochemical d...
