Background & Objective: Angiogenesis plays a key role in different physiologic and pathologic processes. Evaluation of endothelial cells and finally new vessels development in-vivo is a complex and formidable task. Thus, we designed an in-vitro experimental angiogenesis model using human umbilical vein endothelial cells (HUVEC) which is highly reproducible and controllable. This model has appli...
A simple-to-fabricate woven mesh, consisting of bonded laminates of two-dimensional plain-weave conductive screens is described. Geometric equations show that these porous matrices can be fabricated to have a wide range of porosity and specific surface area, . A heat transfer model is developed. It shows that the laminates can have a highly anisotropic thermal conductivity vector, with in-plane...
The geoelectric properties of the geothermal system associated with Tolhuaca volcano were investigated by three-dimensional (3D) inversion magnetotelluric (MT) data. This study presents first resistivity model derived from 3D MT to have a better understanding its magmatic and hydrothermal system. We selected data 54 stations for inversion. performed series tests changing type be inverted, as we...
Considerations associated with inversion of hi-static reverberation and scattering data from a three dimensional space are discussed. The Scattering and Reverberation from the Bottom (SCARAB) acoustic propagation and scattering model has been the kernel for the study. This model considers three dimensional, non-plme wave, range independent acoustic signals in botb mono and hi-static source rece...
This paper describes a theoretical study to investigate the heat transfer characteristics of porous radiant burners. A one dimensional model is used to solve the governing equations for porous medium and gas flow before the premixed flame to the exhaust gas. Combustion in the porous medium is modeled as a spatially dependent heat generation zone. The homogeneous porous media, in addition to its...
Previous breakthroughs in stretchable electronics stem from strain engineering and nanocomposite approaches. Routes toward intrinsically stretchable molecular materials remain scarce but, if successful, will enable simpler fabrication processes, such as direct printing and coating, mechanically robust devices, and more intimate contact with objects. We report a highly stretchable conducting pol...
In this paper, a numerical solution is presented for one-dimensional unsaturated flows in the subsurface. Water flow in the subsurface, however, is highly nonlinear and in most cases, exact analytical solutions are impossible. The method of reference-operators has been used to formulate a discrete model of the continuum physical system. Many of the standard finite difference methods and also th...
A 2D forward modeling code for DC resistivity is developed based on the integral equation (IE) method. Here, a linear relation between model parameters and apparent resistivity values is proposed, although the resistivity modeling is generally a nonlinear problem. Two synthetic cases are considered for the numerical calculations and the results derived from IE code are compared with the RES2DMO...

here in, an application of a new seismic inversion algorithm in one of iran’s oilfields is described. stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of geostatistics and seismic inversion algorithm. this method integrates information from different data sources with different scales, as prior informat...
