Based on a large number of drilling and laboratory test data in Weibei loess tableland area, the correlation three conventional physical mechanical indexes this such as void ratio, compression coefficient collapsibility coefficient, was analyzed studied. The results show that ratio is positively correlated with between higher. obvious when compressibility soil small, but there no large.
As a type of special geological body, soil-rock mixtures (SRMs) are widely found in nature and used civil engineering. Many structures, such as rockfill dams, highways tunnels, have SRMs building materials. Proper modeling is great importance to capture the complex behavior this heterogeneous material. In manuscript, simple constitutive model incorporating skeleton void ratio concept proposed f...
The aim of this review is to investigate the morphological properties of polyimide based SRNF membranes by mean of image processing. Effect of phase inversion parameters like polymer concentration, volatile co-solvent, pre-evaporation time, additives in coagulation bath, polymers weight ratio in composite membranes, addition of nano particles and cross-linking agents have been reviewed. The voi...
Discussion on Revisiting the concept of inter-granular void ratio in view of particle packing theory
Abstract Background and objectives: Ureaplasma urealyticum is one of the most important causes of Nongonococcal urethritis (NGU) and non-specific urethritis (NSU) in men. Also Mycoplasma hominis has a role in causing NGU and NSU. The aim of this study was the detection of Mycoplasma hominis & Ureaplasma urealyticum in men suffering from NGU and NSU by prostatic massage method and first- void Ur...
