Extended surfaces are one of the most important approaches to increase the heat transfer rate. According to the Fourier law, the heat transfer increases by increasing the contact surface of body and fluid. In this study, the effect of heat transfer has been investigated on two sets of engineered porous fins, in which the balls with different materials are sintered together. The fluid flow throu...

Single and ternary solute gas phase adsorption isotherms were conducted in this study to evaluate the effectiveness of a simple constant volume method, which was utilized by using Tedlar gas sampling bags as a constant volume batch reactor. For this purpose, gas phase adsorption of toluene, methyl ethyl ketone (MEK), and methyl isobutyl ketone (MIBK) on two types of activated carbons, BPL-bitum...

We investigate the statistical distribution for ideal Bose gases with constant particle density in 3D box of volume V=L3. By changing linear size L and imposing different boundary conditions on system, we present a numerical analysis characteristic temperature condensate fraction find that smaller is efficient to increase fraction. Moreover, there singularity under antiperiodic condition.

We derive an asymptotic formula à la Lüscher for the finite volume correction to the pion decay constant: this is expressed as an integral over the 〈3π|Aμ|0〉 amplitude after proper subtraction of the pion pole contribution. We analyze the formula numerically at leading and nextto-leading order in the chiral expansion.

We determined the decay constant and distribution space of the MB isoenzyme of creatine kinase after intravenous injection of 440 to 720 U, in a group of seven adult baboons. The rate of decay of the isoenzyme was monoexponential, with a mean decay constant of 0.00175 min-1 (SD, 0.00019). The mean distribution volume obtained by extrapolation of the monoexponential curve to zero time was 5.22% ...

The size of mature oocytes is similar across mammalian species, yet the size of ovarian follicles increases with species size, with some ovarian follicles reaching diameters>1000-fold the size of the enclosed oocyte. Here we show that the different follicular sizes can be explained with diffusion-based limitations on the thickness of the hormone-secreting granulosa layer. By analysing published...

Background and Objectives: Red beet juice, a potential source of valuable nutrients, is widely used as a colorant in food industries. In recent years, to avoid reduction of nutritional values of the red beet during concentration by thermal processing, an osmotic distillation (OD) technique has been suggested. Therefore, the major aim of the present study was to investigate effects of the flow r...
