background: little is known about the effects of a low energy dense diet on weight maintenance and cardiovascular risks following a recent weight reduction. therefore, we assessed if weight maintenance, lipid profiles and glycemic control differ between low energy density diet and usual diet consumers following a recent weight reduction. method s: seventy patients with the history of weight red...
Optical absorption spectra and transmission electron microscopy (TEl\iI) observations-on In&As/ InP layers under compressive strain are reported. From the band-gap energy dispersion, the magnitude of the strain inhomogeneities, Us, is quantified and its microscopic origin is analyzed in view of the layer microstructure. TEM observations reveal a dislocation network at the layer interface the de...
In this article, ZnO and ZnO:Mn nanoparticles prepared by reverse micelle method. The various crystalline properties of these nanoparticles such as size, d-spacing, strain, stress, dislocation density and texture coefficient have been calculated with the help of XRD spectrum. The XRD results indicated that the synthesized ZnO and ZnO:Mn nanoparticles have a pure wurtzite (hexagonal phase) struc...

The phenomenon of surrounding rock damage and rupture caused by high temperatures is widespread, has become a potential threat to the safety nuclear waste disposal repositories. In order reveal energy distribution pattern fractured granite during failure process under different confining pressures, triaxial compression tests were carried out on rocks with initial thermal damage. Firstly, was tr...
In this work, we use the rule of mixtures to develop an equivalent material model in which the total strain energy density is split into the isotropic part related to the matrix component and the anisotropic energy contribution related to the fiber effects. For the isotropic energy part, we select the amended non-Gaussian strain energy density model, while the energy fiber effects are added by ...
