Precipitation measurement using passive or active microwaves from space- ground-based radar involves hypotheses about the raindrop size distribution (DSD). A universal knowledge of DSD characteristics is needed. 4-yr dataset collected with a disdrometer at Dakar, Senegal, on Atlantic coast West Africa used to analyze end continental trajectory Sahelian squall lines. The DSDs are stratified in eight rain-rate classes and fitted analytical distributions. shape averaged found be very similar...

This paper proposes a method for the detection and assessment of degradation photovoltaic modules electrical characteristics such as short-circuit current (Isc), open-circuit voltage (Voc) maximum output power (Pmax). work presents standardization measurements these in real conditions. Standardization is bringing back conditions to corresponding values standard test (STC). Thus standardized (Isc,stc), (Voc,stc) (Pmax) are compared with reference first putting service module or manufacturer's...
The dispersal, population dynamics, and age structure of two Rift Valley Fever Virus (Phlebovirus: Bunyaviridae) (RVFV) vectors, Aedes vexans Meigen Culex poicilipes Theobald, were investigated in northern Senegal. main objective was to investigate possible factors that mediate RVFV emergence propagation at a site where humans livestock live proximity temporary surface pools.
