A boundary layer analysis is presented for the mixed convection past a vertical plate in a porous medium saturated with a nanofluid in the presence of variable viscosity effect. The governing partial differential equations are transformed into a set of similar equations and solved numerically by an efficient, implicit, iterative, finite-difference method. A parametric study illustrating the inf...

The temperature dependency of the total emission intensity and the decay time cone stant of the 5D0 level after the CTB excitation was investigated in various glasses con taming Eu3+, and nonradiative process of Eu3+ center was discussed in connection with the effect of host composition. The broad UV excitation band induced by Eu3+ was considered to be ascribed to the charge transfer states of ...

Terrestrial isoprene emissions directly respond to leaf temperature, photosynthetically active radiation (PAR), soil moisture, and plant characteristics such as leaf area index (LAI). Prior work has estimated isoprene interannual variability at 5e25%, however the relative contributions of individual environmental factors have not been delineated. A biogenic isoprene emissions model (MEGAN) is c...

An accurate prediction of reaction kinetics of silicon nitridation is of great importance in designing procedure of material production and controlling of reaction. The main purpose of the present study is to investigate the effect of temperature on the kinetics of reaction bonded silicon nitride (RBSN) formation. To achieve this, nitrogen diffusion in the silicon nitride layer is considered as...

population in all countries plays a fundamental role in economic growth and economic development. but besides absolute size and growth rate of population, the more important factor will be “age structure” or “age distribution” of population, because it can be as source of many economical, social, and political challenges. in this research, we investigate effect of changes in population shares i...

cellular and tissue activities highly depend on environmental ph. murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. we have studied the effect of ph on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. various concentrations of nahc03 were used to adjust the ph of the culture medium under co...

Temperature dependency of rate constants of edible oil's autoxidation was estimated. One of us showed"' that the rate process of autoxidation of edible oils was expressed by an equation as below, and that the effects of brightness on the rate constants, ko, k,, k2, and k3, in the equation could be measured individually. dP/dt=k0M+k1MP-2k2P2-k3P Here, P is the concentration [mmol/kg-oil] of pero...

In continuum mechanics, the constitutive models are usually based on the Cauchy–Born (CB) hypothesis which seeks the intrinsic characteristics of the material via the atomistic information and it is valid in small deformation. The main purpose of this paper is to investigate the temperature effect on the stability and size-dependency of Cauchy–Born hypothesis. Three-dimensional temperature-rela...
