A SIMPLE EVALUATION METHOD OF THE CONCENTRATION-DISTRIBUTION VALUE FOR CONCENTRATION-DEPENDENT DIFFUSION

Concentration dependent diffusion of self-propelled rods.

We examine the persistent random motion of self-propelled rods (SPR) as a function of the area fraction phi and study the effect of steric interactions on their diffusion properties. SPR of length l and width w are fabricated with a spherocylindrical head attached to a beaded chain tail, and show directed motion on a vibrated substrate. The mean square displacement (MSD) on the substrate grows ...

Evaluation of Neurogenic Potential of Human Umbilical Cord Mesenchymal Cells a Time- and Concentration- Dependent Manner

Background: Retinoic acid as one of the most important regulators for cell differentiation was examined in this study for differentiation of human umbilical mesenchymal cells (hUCM). Methods: After isolation, hUCM were evaluated for mesenchymal stem cell properties by flow cytometry and alkaline phosphatase assay. Also, doubling time of the cells and their differentiation potential into adipoge...

Simple method for concentration of cerebrospinal fluid for protein electrophoresis.

MOST CLINICAL LABORATORIES use paper electrophoresis for the separahon and quantitation of serum proteins. There has been increasing iiiterest in the fractionation of proteins Ill other body fluids, particularly cerebrospinal fluid. Successful paper electrophoresis requires a high protein concentration in the fluid applied to the l)POF strips, If tile total protein content of spinal fluid is no...

The similarity solutions of concentration dependent diffusion equation

This paper deals with the similarity solution of concentration dependent diffusion equation. A fundamental transport process in environmental fluid mechanics is diffusion. A wellknown example is the diffusion of perfume in an empty room. The physical phenomenon of the solute transport due to combined effect of diffusion and convection in a medium is represented by the partial differential equat...
