background: intestinal parasitic infections have a worldwide distribution. high prevalence of intestinal parasitic infections in individuals with low socioeconomic status and environmental conditions was found. no study has ever been conducted on the prevalence of these infections in jiroft. therefore, in this study prevalence of intestinal parasitic infections was evaluated in jiroft, kerman p...

Parallel analyses about the dynamic responses of a large-scale water conveyance tunnel under seismic excitation are presented in this paper. A full three-dimensional numerical model considering the water-tunnel-soil coupling is established and adopted to investigate the tunnel’s dynamic responses. The movement and sloshing of the internal water are simulated using the multi-material Arbitrary L...

Hydroelectric power plants’ open-type surge tanks may be built in mountains subject to the provision of atmospheric air. Hence, a ventilation tunnel is indispensable. The air flow in the ventilation tunnel is associated with the fluctuation of water-level in the surge tank. There is a great relationship between the wind speed and the safe use and project investment of ventilation tunnels. To ob...

Swelling of clay-sulfate rocks is a major threat in tunneling. It is triggered by the transformation of the sulfate mineral anhydrite into gypsum as a result of water inflow in anhydrite-containing layers after tunnel excavation. The present study investigates the hydraulic effects of tunneling on groundwater flow and analyzes how hydraulic changes caused by excavation lead to water inflow into...

Typhoon Aere in 2004 induced severe sedimentation and loss of storage capacity the Shihmen Reservoir northern Taiwan. The resulting dramatic increase turbidity water seriously affected supply. To effectively maintain stability supply reservoir’s capacity, government Taiwan began to plan construct a series improvement measures, such as sediment flushing tunnel, JhongJhuang Bank-Side Reservoir, A...

abstract in order to evaluate crop water stress index (cwsi) and canopy temperature of wheat cultivars under terminal drought stress, a field experiment was conducted at the agricultural research station of shiraz university, shiraz, during 2009 growing season. five wheat cultivars including shiraz, bahar, pishtaz, sistan and yavaros and four levels of water regime including well watering [irr...

background: corrosivity is one of the factors affecting the water quality. not controlling the chemical quality of water in the distribution network causes corrosion, sedimentation and economical and health damages. the aim of this study was to determine the drinking water corrosivity and sediment of kuhdasht, iran by using the corrosivity index. methods: in this study, 12 predetermined areas l...
