Water repellency in forest soils affected by fires and agricultural soils with different agricultural management and abandonment

Cuadernos de Investigación Geográfica, 2013
Soil water repellency determines the water available in the soil system, the runoff generation and the geomorphologic processes. This study examines the soil wettability during the summer of 2008 and 2009 in forest soils with different fire history, and ...

An Experimental Hut Study to Quantify the Effect of DDT and Airborne Pyrethroids on Entomological Parameters of Malaria Transmission. [PDF]

, 2014
Current malaria vector control programmes rely on insecticides with rapid contact toxicity. However, spatial repellents can also be applied to reduce man-vector contact, which might ultimately impact malaria transmission.
