As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact with crude oil and is co-produced with it as well. Considering that asphaltene molecules are pol...

Knowing the overall solute flux and the partial fluxes expressed by every single transport layer, the membrane internal interface concentrations can separately be expressed. Both the overall transport coefcient and the driving force strongly depend, among others, on the value of the structural parameter and the water permeability. Study of the interface concentrations as ...

In the present research, the influences of explosive welding parameters on the corrosion behavior of the three layer explosive welds of the tubes Al 5083 / Al 1050 / stcr18Ni9Ti in the salt environment was investigated. The selected parameters included the stand-off distance and the thickness of the explosive charge. Therefore, two samples A and B were welded with stand-off distances of 6 and 6...

 In this research, a numerical modeling was utilized to calculate the stresses caused during thermal cycling in a functionally graded thermal barrier coating (FG - TBC). The temperature – dependent material response of this protective material was taken into account and the effects of thermal cycle and interface morphology of the ceramic / metallic layer in functionally graded coating system wa...

With the rise in the use of AFM (Atomic Force Microscope), we have witnessed a growing use of atomic microscope based nanorobots in the precise displacement of various particles. There are certain limitations to the application of nanorobots in the moving of nanoparticles. One of the most important of these limitations is the lack of an appropriate image feedback concurrent with the displaci...

Abstract One of the methods of increasing soil resistance against failure is soil reinforcement using geosynthetics. Soil-geosynthetic interactions are of great importance and are affected by friction and adhesion at their interface. Soil gradation, contact surface roughness and geotextile density are among the factors affecting soil-geotextiles interaction this study, to investigate the eff...

 We studied the growth of viscous fingers as a Laplacian growth by conformal mapping. Viscous fingers grow due to Saffman-Taylor instability in the interface between two fluids, when a less viscous fluid pushes a more viscous fluid. As there was an interest in the rectangular Hele-Shaw cell, we solved the Laplacian equation with appropriate boundary conditions by means of conformal mapping tech...

Purpose: evaluation of the user interface of the management system of Iran Public Libraries Foundation (Saman) is the main aim of the paper. Saman is a newly developed web based and integrated library software that seemingly works as a library OPAC.  Methodology: This research is an applied study and tries to investigate the usability standards of Saman website through heuristic evaluation met...
