Impact of Dispersion on Dynamics of a Discrete Metapopulation Model

Impact of Blood Vessel Wall Flexibility on the Temperature and Concentration Dispersion

The analysis of solute and thermal dispersion in pulsatile flow through the stenotic tapered blood vessel is presented. The present problem is an extension of the work done by Ramana et al. who considered the time-invariant arterial wall. In the present model, the flexible nature of the arterial wall through the obstruction (called stenosis) is considered and it is achieved with the he...

Dynamics of a discrete-time plant-herbivore model

Analytical solution of metapopulation dynamics in a stochastic environment.

We study a discrete stochastic linear metapopulation model to understand the effect of risk spreading by dispersion. We calculate analytically the stable distribution of populations in different habitats. The simultaneous distribution of populations in habitats has a complicated self-similar structure, but the population in each habitat follows a log-normal distribution. A class of discrete sto...

Effect of Cyclosporin-A on the Order and Dynamics of DPPC model Membrane Systems

Laser Raman spectroscopy has been employed to investigate the effects of cyclosporine-A on the order and dynamics of DPPC (Dipalmytoyl Phosphatidyl Choline) midel membrane system. It is shown that the addition of small amount of cyclosporine-A to a DPPC dispersion disturb the system and changes the order/disorder parameter of the model membrane.

Dispersion and Deposition of Micro Particles over Two Square Obstacles in a Channel via Hybrid Lattice Boltzmann Method and Discrete Phase model

Dispersion and deposition of aerosol particles over two square cylinders confined in a channel in laminar unsteady vortical flow were investigated numerically. Lattice Boltzmann method was used to calculate fluid characteristics and modify Euler method was employed as Lagrangian particle tracing procedure to obtain particle trajectories. Drag, Saffman lift, gravity, buoyancy and Brownian motion...
