Macrobrachium aemulum madhusoodani Pillai & Unnikrishnan (2013) was recently described based on material from the Neyyar River, Kerala, India as a new subspecies of M. aemulum (Nobili, 1906). As however, both species and subspecies names are considered part of the species-group for nomenclatorial purposes (ICZN, Art. 45.1), the name is a junior homonym of Macrobrachium madhusoodani Unnikrishnan...

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...

The Pontlyfni meteorite fell on Coch-y-Bug Farm, Pontlyfni, Llanwnda, Caernarvonshire, Wales at 11 : 53; April 14, 1931 [1]. Most of the mass is believed to have fallen into the sea, but a 150-g stone was seen to fall on land and was recovered. L.J. Spencer was allowed to examine the stone shortly after its fall, but he could only state that it was a meteori te of an unusual type. The meteorite...

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...

Calcium aluminate cements (CACs) are a group of rapid-hardening hydraulic binders with higher aluminum composition and lower ecological footprint compared to their ordinary Portland cement (CEM) counterparts. CACs commonly known have thermo-durability properties but previously been observed experience major strength loss over time when exposed thermal humidity conditions due the chemical conver...
