surface-piercing propellers (spps) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. unlike the submerged propellers, theoretical methods have no significant application on simulation of sppsbecause of problems related to modeling of these propeller...

Due to considerable stored energy in surfaces of nano-scales in comparison with the stored energy in their bulk, considering the surface energy is necessary for the analysis of various behaviors of nano-scales for more precise design and manufacturing. In this article, the longitudinal dynamic behavior of nanobars in the presence of the surface energy parameters is studied. To this end, the lon...

the armaticity of 5 methylcytosine tautomers in the gas phase has been studied and the chemical structures of related tautomers are investigated . the electronic energy, enthalpy and free energy of each tautomer are also estimated at the b3lyp/6-31 g* // b3lyp/6-31 g* and mp2 / 6-31 g* // mp2 / 6-31 g* levels

Based on the previous article 'Cellular Thermodynamics' (2004) by Joe Wolfe Article contents • Introduction • Equilibrium • Steady state • Heat, light, photons and 'useful energy' • Macroscopic and microscopic views • Distribution of molecules and energy: low energy vs. high entropy • Reaction rates and equilibria • Enthalpy • Gibbs free energy • Other equilibria • The chemical potential • Surf...

We developed surface grid-based solvation free energy density (Surface-SFED) models for 36 commonly used polar solvents. The parametrization was performed with a large and diverse set of experimental solvation free energies mainly consisting of combinations of polar solvent and multipolar solute. Therefore, the contribution of hydrogen bonds was dominant in the model. In order to increase the a...

Structural parameters of raw and pre-treated viscose, modal and lyocell fibres were determined using X-ray diffraction, and compared with data obtained from iodine adsorption and tenacity measurements. A good correlation was found between iodine adsorption and structural changes. These structural parameters are correlated with surface thermodynamic parameters obtained by surface tension experim...

We recalculate the free energy of droplets of quark-gluon plasma in a bulk hadronic medium, and of hadronic bubbles in a bulk quark-gluon plasma, under conditions resembling the cosmological quark-hadron transition. The results are derived using MIT bag boundary conditions, numerically summing over quark and gluon energy levels, as well as in terms of surface tension plus curvature expansions o...
