—The effect of floods and base flow on temporal variation in algal biomass on small smooth streambed stones and creviced sand-cases of the caddisfly (Insecta: Trichoptera) Gumaga nigricula was examined in Big Sulphur Creek in coastal Northern California. Replicates of stones and cases were sampled 34 times over a 14 mo period that included nine floods. Stones had ;23 the algal biomass of cases,...

The ‘outbreak’ of renal stones associated with consumption of melamine-tainted milk products (MTMP) in infants and young children in China, is truly a disaster. By mid October 2008, 47 000 individuals were reported hospitalised with kidney problems related to MTMP-contaminated infant formula consumption, at least four of whom died.1 The outbreak occurred in many regions, but mainly in Ganzu, He...

Physician to the Bristol General Hospital. I have recently attended two patients both of whom passed gallstones , and both of whom noticed a quantity of fine gritty sand in their stools for several days and even weeks during the time that the stones were passing. The stones were of the ordinary type, facetted, varying in size from a hemp seed to a pea, and composed almost entirely of cholesteri...

Manufactured Sand (M Sand) has become a viable alternative for the river sand in construction industry as potential fine aggregate. The M poses environmental implications it is produced by crushing natural resources like stones. extensive use of may also lead to reduction availability due depletion rocks days come. Hence, this study attempts assess feasibility utilizing clayey soil containing K...

Cane and Candy are traceable to two Chinese words both pronounced Kan. One word means Cane or pole when Kan finally became cane in English. The other word Kan means sweet. Then there is the Chinese word Dih which means Drops when Kan-Dih became Candy and means Sweet Drops. Sugar crystals would be like sand in size. Candy of the size of drops.

The Trichoptera fauna was sampled in a first order tributary of Paquequer River, in the district of Teresópolis, Rio de Janerio State. Quantitative samples of litter from pools, litter from riffles, sand, and stones were taken on each season from February 1991 to February 1992. The life cycles of common genera were categorized into three groups of biological strategies. The largest group repres...

Between November 1988 and July 1992 70 patients with radiolucent gall stones were treated with extracorporeal lithotripsy (ESL) and ursodeoxycholic acid (UDCA; mean (SD) dose 11.2 (1.9) mg/kg/day). Fifty three patients have been followed for one year. One week after lithotripsy, 30.6% had completely eliminated all stone fragments from the gall bladder and one year later 93.9% were free of stone...

This paper presents an investigation into the bond strength of three common façade stones, namely, travertine, granite, and marble, to a concrete substrate using shear-splitting test. The effects anchorage, number curing days, presence anti-freezing agent in cement–sand mortar on were studied. results show that days had significant impact between stones substrates. accelerator increased bonding...
