surface-piercing propellers (spps) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. unlike the submerged propellers, theoretical methods have no significant application on simulation of sppsbecause of problems related to modeling of these propeller...

the hydraulic pressure is one of the most important factors in the design of pressure intake tunnels. since the surrounding media cannot usually resist the high internal pressure of these tunnels, they are usually finished with an adequate lining mostly of reinforced concrete, which is an interaction problem between water, soil or rock and concrete lining. although reinforcing the concrete lini...

Culex quinquefasciatus Say mosquitoes flourish in belowground stormwater systems in the southern United States. Recent evidence suggests that oviposition-site-seeking females may have difficulties locating, entering, and ovipositing inside permanent water chambers when surface entry through pickholes in manhole covers are sealed. It remains unknown, however, if newly emerged adults are able to ...

The use of hydrothermal simulation models to improve the prediction of water inflows in underground works during drilling is tested in the Mont-Blanc tunnel, French and Italian Alps. The negative thermal anomaly that was observed during the drilling of this tunnel in 1960 is reproduced by long-term, transient hydrothermal simulations. Sensitivity analysis shows the great inertia of thermal phen...

To study the changes of water and vegetation coverage, groundwater level plant diversity lakes at end Tarim River in Northwest China, various indicators more than 20 years (2000–2019) were analyzed through field investigation indoor remote sensing methods. The results showed that (1): with initiation development ecological conveyance project, areas increased significantly, especially trend beco...

Surface/ground water pollution caused by the inflow of acid water enriched with heavy metals has become a serious environmental problem in the areas around mines [1,2]. This results from the sulfate discharge generated by the decomposition of pyrite contained in the altered rock in mining areas [3]. The same problem has arisen at engineering work excavation sites in recent years [4]. Therefore,...
