Sand plays a crucial role as an important component of concrete. Concrete is widely used construction material. By examining the sand in enhancing workability, strength, and durability, we gain insight into its importance shaping structural integrity available different Mohal Barak Valley like Taranathpur river Dwarbond, Katakhal , Jatinga river, are found to be fail zoning after Particle size ...

Extracorporeal shock wave lithotripsy was performed on 81 patients with urolithiasis (35 patients with ureteral stones, 25 patients with renal stones less than 2 cm in diameter, and 21 patients with renal stones more than 2 cm in diameter) at Kanbara Hospital from August to October, 1986. A 4 Fr catheter was placed transurethrally in the ureter up to the stone to identify the stone position and...

Brown rot fungi belong to the wood-rotting fungi, which produce oxalic acid and actively decompose wood. We first found oxalates formed under action of brown in natural conditions on stone (Rogoselga adit, Karelia, Russia), proposed a model for their formation, confirmed hypothesis that frequent occurrence metal mines adits may be associated with activity these fungi. synthesized four species b...

Giant staghorn common bile duct (CBD) calculi are usually uncommon but can be found in patients with oriental cholangiohepatitis. The size of stone can vary from few millimetres to several centimetres. These are usually pigment stones and patients can present with pain, jaundice and fever or some times Reynold's pentad. Primary bile duct stones form within the bile ducts and usually are of brow...

Ultra-High Performance Concrete (UHPC) improves the bearing capacity as well durability of structural concrete. This study aims to investigate constituents UHPC in both phases: aggregate and cementitious materials. The proper ratio mixture was chosen based on combining an gradation quartz sand crushed stone. In addition, compressive strength hardened cement paste investigated achieve optimal si...

A gravel pit in south central Stearns County, Minnesota exposes sand and gravel of the Merden Lake esker which is thought to have been deposited by a subglacial stream associated with the Wisconsinan-aged Superior Lobe of the Laurentide ice sheet. An analysis of these sediments was conducted from samples collected through a vertical trench on an east-facing exposure of the gravel pit. A total o...

Coral reef benthic communities are mosaics of individual bottom-types that are distinguished by their taxonomic composition and functional roles in the ecosystem. Knowledge of community structure is essential to understanding many reef processes. To develop techniques for identification and mapping of reef bottom-types using remote sensing, we measured 13,100 in situ optical reflectance spectra...
