Prevention of air-entrainment at the outlet of a pumped storage plant – large scale model tests
To avoid the generation of air-entraining vortices at a projected outlet structure in an existing reservoir of a pumped-storage plant, large-scale model tests were conducted. The model, with a scale of 1:18, had the considerable dimensions of 30 m in length and 16 m in width. Due to the complex shape of the reservoir, the many inlets and outlets, and numerous operating conditions, very complex ...
متن کاملMortality of Juvenile American Shad and Striped Bass Passed through Ossberger Crossflow Turbines at a Smallscale Hydroeljktric Site
-A full-recovery technique was used in mortality experiments conducted with juveniles of American shad Alosa sapidissima and striped bass Morone saxatilis passed through Ossberger crossflow turbines to obtain antecedent information about their fish passage characteristics. Immediate turbine-induced mortality was 66% for 85-mm-long (total length) American shad. Turbineinduced mortality of stripe...
متن کاملCohort-Specific Growth and Mortality of Juvenile American Shad in the Pamunkey River, Virginia
—We estimated the variation in instantaneous rates of growth (G) and mortality (M) between intraannual cohorts of juvenile American shad Alosa sapidissima in the Pamunkey River, Virginia. The ages of juveniles captured by push net during the juvenile abundance index surveys in 1998 and 1999 were estimated by counting daily rings on the sagittal otoliths. Weight-at-age and abundance-at-age data ...
متن کاملThe loss of hyperosmoregulatory ability in migrating juvenile American shad, Alosa sapidissima
Investigations on juvenile American shad (Alosa sapidissima) revealed several physiological changes associated with downstream migration. Plasma chloride decreased 20% in wild juvenile shad during the autumn migration. Migrants had lower condition factor and hematocrit than non-migrant shad captured by beach seining. Gill Na+,K+-ATPase activity of migrant shad was higher than non-migrant; a 2.5...
متن کاملOutbreak of Datura Ingestion at a Juvenile Correctional Facility
Case Series: A juvenile correctional facility sent a 16-year-old male resident to the Emergency Department (ED) for medical evaluation. The patient had been confused and had dilated pupils for approximately 8 hours prior to presentation, but the patient and his accompanying guards were unable to provide any additional helpful history. Vital signs were: temperature 37.2OC (oral), pulse 125/min, ...
