Remnant populations of leopard frogs within the Virgin River drainage and adjacent portions of the Colorado River (Black Canyon) in northwestern Arizona and southern Nevada either represent the reportedly extinct taxon Rana onca or northern, disjunct Rana yavapaiensis. To determine the evolutionary distinctiveness of these leopard frogs, we evaluated mitochondrial DNA (mtDNA) restriction site v...

This study determined a practical method to reduce environmental pollution by wastewater from fish ponds. Water quality in three hybrid red tilapia ponds (0.24 ha) was examined before and during harvest at five water depths of 10, 20, 50, 100, 150 cm, as well the surface pond bottom. All samples were analyzed for BOD, TN, TP, TAN, TS, TSS, SS, with results compared Thailand control standard fre...

Groundwater (GW) flooding mechanisms differ from river flooding, both spatially and temporally, preventative methods against groundwater must take this into account. Although caused by a rise of water seldom occurs, it can occasionally become severe last for long time if the is significantly flooded. In southwest portion research domain, Friedrichshafen, Germany, with few urban communities, lev...

Lundin, L. 1994. Impacts of forest drainage on flow regime. Studia Forestalia Suecica 192. 22 pp. ISSN 0039-3150, ISBN 91-576-4872-7. High floods in watercourses are of great interest. because of the potential hazards they pose to people and low-lying land near rivers. In many parts of the world, inundations are common and in northwest Europe there are high discharges almost every year, occasio...

This paper proposes a decentralized control scheme that mitigates floods in urban drainage systems (UDSs). First, we develop partitioning algorithm of the UDS relying on graph model system. Once this is done, design local controller for each partition based replicator dynamics (a set differential equations describes evolution population players involved strategic game). The nature proposed stra...

Superstandard conditions refer to extreme rainfall and river flooding that exceed the flood control system or works. In order explore influence of superstandard on urban waterlogging, based MIKE FLOOD platform, this paper takes downtown area Zhoukou as research object, it conducts waterlogging simulation in under once 20 years 50 combined with ultra-high water level river. The results inundatio...

PURPOSE To evaluate the effect of topical antiglaucoma medications on the lacrimal drainage system. METHODS In a prospective controlled blind observational case series, 627 eyes of 384 patients (219 males, 165 females) were screened. Data recording (demographics and history taking), allocation in case (on topical antiglaucoma medications) and control (no glaucoma) groups, and examinations (ey...
