In areas of the world where malaria prevails under unstable conditions, attacking the adult vector population through insecticide-based Indoor Residual Spraying (IRS) is the most common method for controlling epidemics. Defined in policy guidance, the use of Annual Parasitic Incidence (API) is an important tool for assessing the effectiveness of control and for planning new interventions. To in...

erosion is one of the important social-economic problems in iraniancatchments that have been posed by surface water vastness and runoff production. so, thestudy of water resources, soil erosion and effective factors is of high importance. gullyerosion also extends in many parts of iran and its study particularly in viewpoint ofsediment yield is therefore very important and should be taken into ...

Flash floods are the most dangerous processes in Seine-Maritime (northern France) due to their sudden onset and rapid rising time. Such floods shortly follow high rainfall, ranging from 50 to up to 100 mm in less than 6 hours, and occur in small (< 20 km2) and dry valleys, in which a surge rushes down through the main valley just a few minutes after rains have peaked. Phenomena currently produc...

White-tailed deer are an important reservoir for pathogens that can contribute a large portion of microbial pollution in fragmented agricultural and forest landscapes. The scarcity of experimental data on survival of microorganisms in and release from deer feces makes prediction of their fate and transport less reliable and development of efficient strategies for environment protection more dif...

The research of saltwater upconing is crucial for the development and utilization island freshwater resources. In this paper, a laboratory physical experiment device was developed, recovery lenses were investigated using rainfall simulations single-well multi-well pumping tests with various intensities. results revealed that: (1) thickness lens increased continuously linearly during early stage...
