CDCminiature light traps were used to evaluate the general biology of phlebotomine sand ßies from April 2003 to November 2004 at Tallil Air Base, Iraq. Factors evaluated include species diversity and temporal (daily and seasonal) and geographic distribution of the sand ßies. In addition, the abundance of sand ßies inside and outside tents and buildings was observed. In total, 61,630 sand ßies w...

sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. over thepast decade a large part of iran has been affected by this phenomenon, and tehran has not been excluded from thisevent. therefore, having knowledge of spatiotemporal frequency variations can aid us in future management andstorm trajectory assessment. in this study the synoptic anemo...

The physical development of cities is always faced with natural barriers. The physical development of the city of Zabol, located in the Sistan plain, is threatened specifically with the development of sand dunes. For this reason, the region’s drought conditions were investigated and the standardized precipitation index was calculated. The results showed that with the drying of Hamoon Lake, the ...

The effects of various growing substrates, combinations of soil, silt, sand, press mud (PM) and rice hulls (RH) on plant growth, yield and quality of rose (Rosa hybrida L.) cvs. Kardinal, Anjlique and Gold Medal, were studied to standardize substrates for cut rose production and develop better management and quality production protocol. Plant height, number of leaves branch, leaf area, number o...

CDC miniature light traps were used to evaluate the general biology of phlebotomine sand flies from April 2003 to November 2004 at Tallil Air Base, Iraq. Factors evaluated include species diversity and temporal (daily and seasonal) and geographic distribution of the sand flies. In addition, the abundance of sand flies inside and outside tents and buildings was observed. In total, 61,630 sand fl...

This paper presents the results of an evaluation of the effects of a local water harvesting project in Kenya concerning the construction of small scale sand dams by communities. Sand dams are small structures built in ephemeral rivers to store excess water to overcome periods of drought. For this evaluation we developed a method using socio-economic vulnerability indicators, which are linked to...
