asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
short story as an important literary genre in the recent decade is focused by many of young writers and literary critical with searching structure, content , artistic techniques and cognitive phenomenon of these works , we can show quantity of using some parts of storied literature from new literal techniques of the word and also we can show the usage of native, cultural and social foundation...

ocean waters often show layered structures especially where exchange flow between two basins occurs. these structures are often attributed to processes such as double.diffusive convection, internal waves, turbulent modulated mixing. in this paper by examining the vertical structures of temperature, salinity and density, of the middle parts of caspian sea it is shown that such layered structure ...
The generative revolution in linguistics, started in the 1950s, culminated around 1980, when it was demonstrated that “rules of grammar” were not construction-specific, as had been believed since Antiquity, but following from the interactions of various constructionindependent principles. Perhaps most important among those principles were the locality principles, with such well-known highlights...
We describe the current state of knowledge about Mercury’s interior structure. We review the available observational constraints, including mass, size, density, gravity field, spin state, composition, and tidal response. These data enable the construction of models that represent the distribution of mass inside Mercury. In particular, we infer radial profiles of the pressure, density, and gravi...
the internal structure of dna-ctab and dna-ddab is investigated by a small angel x- ray scattering(saxs) instrument. hexagonal packing of dna was observed for dna complex with ctab, and for ddabcomplex is observed lamellar structure. variations in the internal spacing and degree of long-range ordering aredependent on both surfactant type and concentrations of added salt. when we increased the a...
