PURPOSE To retrospectively assess the clinical utility in ureteroscopy (URS) planning of cumulative stone diameter (CSD), which does not account for stone width or depth, as a predictor of URS outcome and compare it with stone volume. MATERIALS AND METHODS Patients with renal stones treated at a single institute by flexible URS were retrospectively evaluated. To assess the clinical utility of...

Macrobrachium snpurii sp. nov., collected from the Karamana River, in the lower reaches of Western Ghats, is described and illustrated. DNA barcoding using Cytochrome B gene sequences has elucidated the taxonomic status of the new species and the NJ tree reveals that M. snpurii sp. nov., is phylogenetically close to M. idella idella. However, morphometric and meristic features of the species sh...

Adsorption kinetics of As and Pb onto composite beads synthesized with stone powder, chitosan, maghemite (SCM beads) weight ratio 1:1:0.5 were investigated in batch mode. Several kinetic models such as pseudo-first order model (PFOKM), pseudo-second (PSOKM), two compartment first (TCFOKM), modified (MTCFOKM) utilized to analyze the kinetics. Although had low specific surface area pore volume, M...

The use of high-strength sandy concrete (HSSC) is an alternative to crushed stone. Its profitable for those regions Russia in which stone imported building material. Thus, supplied the Republic Tatarstan (RT) from Ural, and local reserves sand are significant. Authors presented results studies determine economic efficiency solid columns’ erection one-story industrial buildings with bridge crane...

Let X be a completely regular space and let A(X) be a ring of continuous real-valued functions onX which is closed under local bounded inversion. We show that the structure space of A(X) is homeomorphic to a quotient of the Stone–Čech compactification of X. We use this result to show that any realcompactification of X is homeomorphic to a subspace of the structure space of some ring of continuo...

With the development of urban underground space and increased infrastructure functions, both scale engineering construction difficulties have globally. In structures in soft strata, especially coastal areas, limited bearing capacity foundations poses a significant challenge. The composite pile technologies employing an organic combination rigid andthe flexible column can enable efficient ground...
