A study was done of the bionomics, insecticide susceptibility and irritability status of Anopheles culicifacies in Sistan va Baluchestan province. Sampling was performed to determine the following parameters: species identification, seasonal activity, adult and larval susceptibility tests, irritability tests, anthropophily index and sporozoite rate. An. culicfacies adults were susceptible to al...

The safety of a ship is studied using the theory of "safe basin" in this paper. The safe basins of the single degree of freedom (rolling) in waves and winds are investigated. The influences of a static heel angle, waves and winds to the safe basin erosion are examined. It is found that the shape of the safe basin is changed when a static bias angle takes place, and the area of the safe basin de...

Abstract Since eroded sediments are produced from different sources distributed throughout a basin, sediment delivery processes at basin scale have to be modelled by a spatially distributed approach. In this paper a new theoretically based relationship is proposed for evaluating the sediment delivery ratio, SDR{, of each morphological unit, i, into which a basin is divided. Then, using the sedi...

Site U1324 is the westernmost site drilled in the Ursa basin by Expedition 308. Of the three sites in the Ursa Basin, Site U1324 has the thickest sediment loading above the permeable Blue Unit. The principal objectives of drilling Site U1324 were to document rock physical properties at the location of maximal overburden in the Ursa Basin, measure in-situ formation temperature and pressure, docu...

in iranian archaeology, sistan played an important role especially in the parthian period. this region is well known since it was cross road for greeksto reach the east, a place for scythians arrival, the presence of powerful suren pahlav clan and the place of epic and heroic tales. during the parthian era favorable environmental conditions of sistan caused to arise many of towns and settlement...
