Dependence of the radiative-convective equilibrium structure lower atmosphere Venus on specification atmospheric thermodynamic model is investigated. A series models including ideal gases, van der Waals and real gases are introduced by use Helmholtz energy given EOS-CG mixture (EOS-CG: Equation State for Combustion Gases Gas-like Mixtures). It demonstrated that profile gas differs significantly...

Batch culture of Ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. The gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...

We study thermodynamic properties of weakly interacting Bose gases above the transition temperature Bose-Einstein condensation in framework a perturbation theory. Cases local and non-local interactions between particles are analyzed both analytically numerically. obtain compare dependencies for chemical potential, entropy, pressure, specific heat to those noninteracting gases. The results set r...

The nonlinear dynamics of and heat and mass transfer processes in annular liquid jets are analyzed by means of a nonlinear system of integrodi€erential equations which account for the liquid motion and the gases enclosed by the jet. Both linear and sinusoidal heat and mass addition sources are considered to take place homogeneously within the volume enclosed by the jet's inner interface in an a...

introduction nowadays, due to higher environmental pollution and decreasing fossil fuels many countries make decisions to use renewable fuels and restrict using of fossil fuels. renewable fuels generally produce from biological sources. biodiesel is an alternative diesel fuel derived from the transesterification of vegetable oils, animal fats, or waste frying oils. considering the differences be...

Changes in temperature and body heat were measured in 30 patients. Despite the warming of most fluids given intravenously, all the patients ventilated with dry anaesthetic gases became cooler, with an average heat loss of 12.4 kilocalories per hour. In a group to whom the gases were delivered saturated at body temperature, the average hourly loss was 1.5 kilocalories. This difference is in agre...
