In the present paper, we have studied the influence of heat transfer and magnetic field on a peristaltic transport of a Jeffrey fluid in an asymmetric channel with partial slip. The complicated Jeffrey fluid equations are simplified using the long wave length and low Reynolds number assumptions. In the wave frame of reference, an exact and closed form of Adomian solution is presented. The expre...

asymptotically exact and nonlocal third order nonlinear evolution equations are derivedfor two counterpropagating surface capillary gravity wave packets in deep water in thepresence of wind flowing over water.from these evolution equations stability analysis ismade for a uniform standing surface capillary gravity wave trains for longitudinal perturbation. instability condition is obtained and g...

We obtain new gauge-invariant forms of two-dimensional integrable systems of nonlinear equations: the Sawada–Kotera and Kaup–Kuperschmidt system, the generalized system of dispersive long waves, and the Nizhnik–Veselov–Novikov system. We show how these forms imply both new and well-known two-dimensional integrable nonlinear equations: the Sawada–Kotera equation, Kaup–Kuperschmidt equation, disp...

Sine, triangular and square wave alternating currents were used to anaesthetize young buffalo calves. Central venous pressure, systolic and diastolic blood pressure and circulatory rate were monitored before, during and after application of currents. The square and triangular wave current produced a significant (P less than 0.01) increase in central venous pressure, mean systolic and diastolic ...

Equations for the wave-averaged three-dimensional momentum equations have been published in this journal. It appears that these equations are not consistent with the known depth-integrated momentum balance, especially over a sloping bottom. These equations should thus be considered with caution as they can produce erroneous flows, in particular outside of the surf zone. It is suggested that the...

Using data from an original two-wave panel survey of California high school students and a two-wave panel survey of high school students in Chicago, we find that different pedagogical approaches influence different forms of civic and political engagement. Specifically, controlling for prior levels of engagement and demographic factors, we find that open discussion of societal issues promotes en...
