‎the water wave generation by wave paddle and a freely falling rigid body are examined by using an incompressible smoothed particle hydrodynamics (isph)‎. ‎in the current isph method‎, ‎the pressure was evaluated by solving pressure poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure poisson equation contains both of divergence free ve...

A two-dimensional nonlinear aerodynamics representation analysis is proposed for the investigation of inviscid flowfields of unsteady airfoils. Such problems are reduced to the solution of a nonlinear multidimensional singular integral equation as the source and vortex strength distributions are dependent on the history of these distributions on the NACA airfoil surface. A turbulent boundary la...

Cellular Physiology 1. Define the distribution of solutes between the intracellular and extracellular compartments. 2. Define passive, active and secondary active transport across the cell membrane. 3. Define the equation and the variables that determine the flux of an uncharged solute by simple diffusion, i.e. Fick’s law of diffusion. 4. Define the role of membrane voltage, concentration gradi...

A manifestly covariant relativistic statistical mechanics of the system of N indistinguishable events with motion in space-time parametrized by an invariant “historical time” τ is considered. The relativistic mass distribution for such a system is obtained from the equilibrium solution of the generalized relativistic Boltzmann equation by integration over angular and hyperbolic angular variable...

Rubbery materials can undergo deformation induced microstructural changes leading to softening of response and permanent set. In this work, these materials are modeled by a constitutive equation that incorporates the following micromechanism : when the deformation becomes large enough, network junctions break during further increments of deformation and then heal. New networks are formed by thi...

Asthma is a chronic disease in Barbados with a mean of 10,348 cases per year. This study was undertaken to determine the demographic distribution of the asthmatic attacks, their relationship with several meteorological variables and to provide a predictive equation. The study used data on asthmatic attacks provided by the Accident and Emergency Department of the Queen Elizabeth Hospital and met...
