In this research, a pilot study and analysis of an innovative multi-channel photovoltaic/thermal (MCPV/T) system in a geographic location (35° 44' 35'' N, 50° 57' 25'' E) has been carried out. This system consists of integrating a photovoltaic panel and two PV/T heat-sink converters. The total electrical, exergy and energy efficiencies of the system at air flow rate of 0.005 kg/s and radiation ...
Introduction: The aim of this study was to eva-luate the salivation flow rate objectively using Schirmer test and mouth dryness and other consequences subjectively by distributing questionnaires to patients receiving head and neck radiotherapy. Materials and Methods: In this descriptive study that was carried out at Imam Khomeini hospital, Tehran, Iran, the saliva flow rate of 33 patients r...
cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...
background: flow cytometry is a rapid, sensitive, and reliable method for determination of bacterial viability. here we assayed the capability of flow cytometry to detect helicobacter pylori viable cells in both forms of spiral and coccoid. methods: viable bacteria stained with rhodamin 123 and fluoresced with laser beam of 488nm. the rate of rh123 absorption was determined in both forms of bac...
