Human Adenoviruses (HAdV) are notably resistant in the environment. These agents may serve as effective indicators of fecal contamination, and may act as causative agents of a number of different diseases in human beings. Conventional polymerase chain reaction (PCR) and, more recently, quantitative PCR (qPCR) are widely used for detection of viral agents in environmental matrices. In the presen...

Collapse sinkholes are common in areas where gypsum strata underlie rock that is incompetent to bridge the cavities created by groundwater dissolution of gypsum. On floodplains these can be obscured due fill overbank deposits, and channels tend migrate towards larger enclosed depressions. This study utilises GIS analyse influence exerted small collapse on channel dynamics alluvial River Ure, UK...

Development of virgin and fallow lands in Kazakhstan has highlighted a number problems the economy republic. Introduction huge territories into land turnover extreme conditions required search creation irrigation system North-Kazakhstan region. Authors note that region, having difficult natural-climatic caused by sharply continental climate, there was deficit fresh artesian water. Therefore, on...

This thesis explores speleogenesis within the Dartry Limestone Formation of Cuilcagh Mountain by considering the hydrogeology of the aquifer in the modern setting but also by considering its evolution since it was deposited during Asbian (Dinantian) times. Due to the synclinal structure of the region, which gently plunges northwestwards, the aquifer remains buried beneath the upland and is not ...

Widespread flooding of the Australian continent during Early Cretaceous, referred to as Eromanga Sea, deposited extensive shallow marine sediments throughout Great Artesian Basin (GAB). This event had been considered ‘out sync’ with eustatic sea level and was instead solely attributed dynamic subsidence associated Australia's passage over eastern Gondwanan subducted material. However, mantle co...

BACKGROUND Inorganic arsenic (iAs) is carcinogenic to humans. Methylated metabolites of arsenic (As) found in the urine could serve as potential tools for screening and early detection of cancer in populations exposed to As. Relatively little information is available regarding changes in As methylation profiles after cessation of As exposure. OBJECTIVE We examined the changes in urinary arsen...

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...
