The distribution of dark matter in dwarf galaxies can have important implications on our understanding galaxy formation as well the particle physics properties matter. However, accurately characterizing content is challenging due to limited data and complex dynamics that are difficult model. In this paper, we apply spherical Jeans modeling simulated stellar kinematic spherical, isotropic with g...
Background and Objectives: As chemical methods are commonly used to modify the starch properties, in this study, the influence of chemical modification using POCl3 on the rice starch function was evaluated. Materials and Methods: Rice starch was isolated by alkaline extraction of the proteins and cross-linked rice starches were prepared from reactions between native rice starch (low and high a...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
The ability to produce robust and functional cross-linked materials from soluble and processable organic polymers is dependent upon facile chemistries for both reinforcing the structure through cross-linking and for subsequent decoration with active functional groups. Generally, covalent cross-linking of polymeric assemblies is brought about by the application of heat or light to generate highl...
The way of making cross-linkable polyethylene through silane grafting has gained much attention in recentyears because of its various advantages such as easy processing, low cost and capital investment andfavorable properties in the processed materials. This work deals with silane grafting and moisture crosslinkingof linear low density polyethylene (LLDPE). The grafting reaction was performed i...
