The mode of action of spatial repellents and their impact on vectorial capacity of Anopheles gambiae sensu stricto. [PDF]

, 2014
Malaria vector control relies on toxicity of insecticides used in long lasting insecticide treated nets and indoor residual spraying. This is despite evidence that sub-lethal insecticides reduce human-vector contact and malaria transmission.

Effects of hydrophobicity on splash erosion of model soil particles by a single water drop impact [PDF]

, 2013
Raindrop impact can be a major contributor to particle mobilization for soils and other granular materials. In previous work, water repellent soils, comprised of hydrophobic particles, have been shown to exhibit greater splash erosion losses under ...
