Rainwater harvesting (RWH) is a relatively inexpensive technology that has the potential to provide safe water in communities where conventional technologies are difficult to implement. In this study, the microbiological quality of rainwater harvested from rooftops and ground-surface runoff was evaluated based on the concentrations of Escherichia coli, total coliforms and enterococci. Samples w...

Background Leishmania tropica, the causative agent of anthroponotic cutaneous leishmaniasis (ACL), and Leishmania major, which causes zoonotic cutaneous leishmaniasis (ZCL), are endemic in Iran. Methods Cross-sectional study was designed to identify Leishmania species in cutaneous leishmaniasis patients who referred to Mashhad Health Centers from 2013 to 2014 using ITS-PCR-RFLP technique. Fir...

introduction: beta-thalassemia is the most common hereditary disease in iran. more than two million carriers of beta-thalassemia live in iran. since the iranian population is a mixture of different ethnic groups, it is necessary to determine the frequency  in the different parts of the country. materials and methods: this descriptive study is a cross sectional study with helping by professional...

R. Razavi, M. Fleury and M. Ghanbari By selecting from Bluetooth’s Enhanced Data Rate (EDR) packet types according to channel conditions, optimal data-rates are approached, especially if Forward Error Control (FEC) is extended to EDR. This Letter presents correct calculation of these packet types, which also accounts for Double Adjacent Error Correction (DAEC) in addition to conventional Single...

because of low spatial resolution and simplifications in meteorological processes in global circulation models, they cannot sufficiently simulate the weather, comparing to the regional models; then, spatial and temporal downscaling of the gcm outputs are needed for decreasing errors of the global circulation models. there are two methods of downscaling: statistical and dynamic. weather generato...
