Second Movement: Motivation

Analytical and Numerical Investigation of Second Grade Magnetohydrodynamics Flow over a Permeable Stretching Sheet

In this paper, the steady laminar boundary layer flow of non-Newtonian second grade conducting fluid past a permeable stretching sheet, under the influence of a uniform magnetic field is studied. Three different methods are applied for solving the problem; numerical Finite Element Method (FEM), analytical Collocation Method (CM) and 4th order Runge-Kutta numerical method. The FlexPDE software p...

Suitable Starting of a Small Teaching Group

  Using small groups in teaching and learning has a long history. Evidence suggests that by applying some defined guidelines, it would be possible to reinforce the effectiveness of the small groups teaching. One of these guidelines is related to ice-breaker activities which would be applied by the facilitators at the start of the session, which are noticeably significant. The aim of the presen...

Unsteady Magneto Hydro Dynamic Flow of a Second Order Fluid over an Oscillating Sheet with a Second Order Slip Flow Model

Unsteady slip-flow of second grade non-Newtonian electrically conducting fluid over an oscillating sheet has been considered and solved numerically. A second-order slip velocity model is used to predict the flow characteristic past the wall. With the assumption of infinite length in x-direction, velocity of the fluid can be assumed as a function of y and t, hence, with proper variable change pa...

Starting Over: The Search for Endogenous NKT Cell Ligands

Like a circus performer in a highwire act, the human immune system teeters on a precarious perch. It must continually balance an effective defense against microbial invaders with the need to avoid the kind of inappropriate immune activity that leads to autoimmune disease. The consequences of a misstep can be disastrous. Natural killer T (NKT) cells, a specialized type of T cell, constitute one ...
