Copper ore processing generates a large amount of copper slag, which has properties that are similar to fine aggregate. slag promising future in the construction industry as an alternative Up 50% aggregate substitutions have been successful. The performance concrete could be improved by microbiologically induced calcium carbonate precipitation. impact micro-organisms on mechanical and flexural ...

Drugs from the sea? Darwin may not have considered this concept when he was thinking about mechanisms that drove diversification of life on earth. In recognition of his 200th year, and celebration of the publication in 1859 of his "On the origin of species", we review the global status of marine biodiscovery in medicinal fields, with a focus on the South Pacific.

BACKGROUND The Randomized Intervention for Children with Vesicoureteral Reflux (RIVUR) trial found that recurrent urinary tract infections (rUTI) with resistant organisms were more common in the trimethoprim-sulfamethoxazole prophylaxis (TSP) arm. We describe factors associated with trimethoprim-sulfamethoxazole (TMP-SMX) resistance of rUTIs in RIVUR. METHODS Children aged 2 to 71 months with...

BACKGROUND Post-operative endophthalmitis is a serious complication of intraocular surgery which may present acutely or chronically.
