This paper was aimed to address the modeling of effective thermal conductivity and viscosity of carbon structured nanofluids. Response surface methodology, D_optimal design (DOD) was employed to assess the main and interactive effects of temperature (T) and weight percentage (wt %) to model effective thermal conductivity and viscosity of multi wall and single wall carbon nanotube, CVD and RGO G...

In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...

INTRODUCTION Tracheal wall thickness is a substantial indicator in various pathological changes. The present study was performed to compile normative data and formulae for the tracheal wall thickness and volume at varying gestational age. MATERIAL AND METHODS Using anatomical dissection, digital image analysis and statistics a range of the wall thickness, proximal internal-to-external cross-s...

background: early clinical investigations indicate that an infusion of autologous bone-marrow cells into the infarct-related coronary artery is feasible after acute myocardial infarction. there is increasing evidence that cell transplantation may improve the perfusion and contractile function of the ischemic myocardium . the present study reports primarily the safety of intracoronary bone marro...

We investigate vortex partition functions defined from integrals over the handsaw quiver varieties of type A1 via wall-crossing phenomena. consider by two types cohomology classes, and get functional equations for each them. also give explicit formula these functions. This gives proofs to suggested physicists. In particular, we obtain geometric interpretation formulas multiple hypergeometric in...
