background: the control of leishmaniasis, a tropical neglected disease, has been concern of iranian health authori­ties due to the increasing number of cases during the last two decades. the objective of this study was to determine del­tamethrine residue on the impregnated bed nets using hptlc technique in a leishmaniasis control program in iran. methods: during this experimental study, a total...

Luffa Cylindrica (LC) is the dried fruit of a sponge-type plant belonging to Curcubitacea family. Recent advancements in hierarchical and lightweight structures have aroused interest this natural fibrous material for illustrating an extraordinary multi-porous architecture high anisotropy low density. To extent its biodegradable nature, such structure potentially apt replace conventional porous-...

Phase change materials (PCMs) have received extensive attention due to their high latent heat storage density and isothermal behavior during charging discharging processes. The application of PCMs in buildings would match energy supply demand by using solar effectively, thereby reducing building consumption. In this study, a diatomite/paraffin (DP) composite was prepared through vacuum-impregna...

The extraction of gold involves using cyanide which has the potential to impact the environment. Many studies have been done to reduce the environmental effects of cyanide. In this research, the cyanide adsorption on zeolite from gold processing plant tailing dam wastewater was investigated. Results indicated that the pH of the solution, contact time duration, temperature, zeolite amo...

Water management is crucial for reliable operation of Polymer Electrolyte Membrane Fuel Cells (PEMFC). Here, the gas diffusion layer (GDL) plays an essential role as it has to ensure efficient water removal from and oxygen transport catalyst layer. In this study through porous carbon felt GDLs was simulated using a 3D Color-Gradient Lattice Boltzmann model. Simulations were carried out on micro...

The variations in the low frequency dielectric spectra of mass impregnated insulation depending on its moisture content have been investigated. For the calibration purposes a number of the impregnated paper samples was kept in the desiccators where different relative humidities were maintained. Thus obtained moisture content in the samples ranged from 1 % up to 6 %. The variations of the comple...

an interventional field trial study was carried out in the dehdahst area, kohgiloyeh & buyer ahmad province, iran, during 1997-1998. efficacy of deltamethrin-impregnated bednet at target dosage of 25 a.i. mg/m2 and the incidence of malaria were compared in treated and untreated villages. in this area anopheles superpictus is the dominant species and the activity of the species occurs in one pea...
