Wind regime and sand grain size are two of the factors that determine the morphology and dynamics of sand dunes in desert areas. Regarding the importance of wind effects on sand dunes especially in Iran, in this study, Khartooran Erg was analyzed to determine wind direction and to detect sand source sites. Khartooran Erg is located on eastern north of Iran and lies in Khorasan Razavi and Semnan...

the identification of natural hazard prone areas for future planning requires an efficient decision support tool to provide the appropriate weights for the various topographical, geological, and seismological factors responsible for the expected hazards. in the present study, an analytical hierarchy process (ahp) with six earthquake hazard parameters (ehps) was used as a decision support system...

Abstract Background Response time to cardiovascular emergency medical requests is an important indicator in reducing disease (CVD) -related mortality. This study aimed visualize the spatial-time distribution of response time, scene and call-to-hospital these requests. We also identified patterns clusters CVD-related calls. Methods cross-sectional was conducted Mashhad, north-eastern Iran, betwe...

background: daylight availability data are essential for designing effectively day lighted buildings. in respect to no available daylight availability data in iran, illuminance data on the south facing vertical surfaces were estimated using a proper method. methods: an illuminance measuring set was designed for measuring vertical illuminances for standard times over 15 days at one hour interval...

Information on the prevalence and risk factors for HIV infection among sailors is scarce. The aim of this seroprevalence study was to evaluate the frequency of HIV infection among sailors in south of Iran using rapid HIV test. The study included 400 consecutive participants in Lengeh, Shahid Rajaie, and Shahid Bahonar ports in south of Iran in May 2010. We observed only one case (0.25%) of HIV ...

[1] We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500–400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a mi...

Two species of mutillids, Smicromyrme (Astomyrme) nikolskajae Lelej, 1985 and S. (Eremotilla) tekensis Skorikov, 1935, reared from puparia of ber fruit fly, Carpomya vesuviana Costa, in South Khorasan, Iran are recorded. Both mutillids are newly recorded from Iran. An overview of eight species of mutillids associated with six species of flies is given in the appendix.

At present no war is being fought in SEE. However this outward tranquility was imposedfrom outside through energetic military interventions by the West, the establishment of international military and security protectorates over parts of the region, as well as by stationing peace-keeping troops, international police, armed and unarmed foreign observers at the hottest trouble spots in SEE. The s...

Observed upper ocean currents south of Sri Lanka exhibit large, irregular fluctuations with periods of days to weeks. An ocean model driven by daily surface winds is able to reproduce the observed fluctuations. We find from model experiments that low frequency (30-50 day) intraseasonal variability (ISV) arises when Rossby waves radiated from the eastern boundary are amplified by hydrodynamic in...
