Distribution and seasonality of vertically transmitted dengue viruses in Aedes mosquitoes in arid and semi-arid areas of Rajasthan, India.
BACKGROUND & OBJECTIVES Transovarial transmission of dengue virus is a crucial etiological phenomenon responsible for persistence of virus during inter-epidemic period of the disease. Distribution and seasonality of this phenomenon in disease endemic areas may contribute to explain emergence of dengue and its subsequent prevention. The study on seasonal and area distribution of transovarial tra...
متن کاملEntomological studies for surveillance and prevention of dengue in arid and semi-arid districts of Rajasthan, India.
BACKGROUND & OBJECTIVES Rajasthan is one of the dengue endemic states of India. Very few studies have been published on entomological aspects of dengue in this state. Owing to water scarcity, inhabitants in desert areas overstore domestic water which leads to the persistence of dengue vectors within the domestic premises. Area specific knowledge on breeding, key containers and seasonal rhythms ...
متن کاملInvestigation of Sedimentation of Small Catchments under Precipitation Pattern and Basin Characteristics in Arid and Semi-Arid Climate
Splash (raindrop) erosion plays an significant role in soil loss, especially in arid and semi-arid regions with poor vegetation. In this paper, by analyzing the pattern of rainfalls that occurred during 26 years in four basins located in Semnan County, their effect on the pattern of eroded sediments from the basin was investigated. Sedimentary layers from the sampling of retarding reservoir sed...
متن کاملReturns and Economic Efficiency of Sheep Farming in Semi-arid Regions: A Study in Rajasthan
The economics of sheep-farming and its economic efficiency have been reported using field level data collected from the semi-arid regions of Rajasthan in 2005. The net return per average flock of 54 has been found Rs 25000 per year. The sheep-farming activity attracts labour employment of 581 mandays per annum, more than three-fourths of which is engaged in grazing. The female labour has been f...
متن کاملSimulation of the catchments hydrological processes in arid, semi-arid and semi-humid areas
Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...
