Innovative membrane filtration plants for municipal wastewaters are being developed and need the support of reliable models in designing phase. In past, semi-empirical processes have been proposed. At present, most prominent works point out importance particle poly-dispersity development but fail into implementation probability density functions (PDFs) capable an accurate fitting experimental s...

cation exchange capacity and specific surface area are among some of the important soil characteristics the direct measurement of which is laborious, costly and time consuming. therefore, fractal dimension of particle size distribution has been widely studied in relation with many such dynamic and static processes as transmission of water and solutes, water holding capacity, heat storage and co...

The paper considers the issues of energy consumption and effectiveness using aluminous slag as an expansion agent compared to Portland cement. Aluminous is a difficult material grind, but its use additive in demand for building materials. following research methods were used: grinding materials, sieve analysis, electron microscopy. According results studies, it was found that effective

polydimethylsiloxane (pdms) has been synthesized by ring-opening polymerization of octamethylcyclotetrasiloxane (d4) in microemulsion with acidic catalyst. the structure and properties of microemulsion were characterized by transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir), photo correlation spectroscopy (pcs). the effect of the variation in ph value, amoun...
