Mosquito control with the use of insecticides is faced with the challenges of insecticide resistance in disease vectors, community refusal, their high cost, operational difficulties, and environmental concern. In view of this, integrated vector control strategies with the use of larvivorous fishes such as Guppy (Poecilia reticulata) and Gambusia (G. affinis) as biological control agents were us...

We propose a flexible framework for evaluating prospect dependencies in oil and gas exploration and for solving decisionmaking problems in this context. The model uses a Bayesian network (BN) for encoding the dependencies in a geologic system at source, reservoir, and trap levels. We discuss different evaluation criteria that allow us to formulate specific decision problems and solve these with...

in order to determine the control of breeding sources of culex larvae in sewage wells by the larvicide abate, some studies were performed in the summer and autumn of 1972. in general, it was noticed in these studies that:1. the wells chosen as a control (5 wells) were active throughout the study periods and adult mosquitoes were captured plentifully. 2 in 4 sewage wells which were controlled by...

nitrate has been the most common chemical contaminant in water resource. this ion is introduced into the water via different ways, but more items of nitrate pollution was connected with farming-based drainage and sewage effluent. in this descriptive-analytical study, groundwater nitrate and nitrite concentrations of 8 wells on dehloran, ilam, iran, were analyzed in 2015 to determine the causes ...
