Water use as a heat storage material in solar water heaters (SWH) has disadvantages, including its low energy density, which requires large volume of thermal storage. Phase-change (PCM) is latent type that the advantage being high density. Therefore, PCM quite interesting to be applied SWH systems. In operation SWH, it necessary know characteristics hot usage. This paper aimed determine continu...

The demand for electricity and the need to replace fossil fuels by renewables have been growing steadily, this transition will significant implications our world that are only beginning be understood. Brazil is one important example of a big economy where already supplied renewables, such as hydro, wind biomass-fired thermal power. In work we investigated load curves in last 20 years Brazil, fo...

dry areas near the sea can obtain fresh water through solar distillation of saline sea water resources. however, these solar distillation sites produce wastewater as a result of desalination of sea water with high salt concentration. waste must be disposed of with the least effect on the receiving environment (sea, in most cases). initial dilution and its characteristics play important roles in...

Background & Aims of the Study: The safe drinking water providing is one of the most crucial objections in these centenaries. Bacterial water contamination and high rate of morbidity and mortality is crucial health threat. Efficiency of potassium persulfat (KPS) associated solar disinfection as a novel water disinfection technology was evaluated in batch scale experiments, us...

Thermal Conduction Heating (TCH) is a major component of In Situ Thermal Desorption (ISTD), a soil remediation technology in which heat and vacuum are applied simultaneously. Heat flows into the soil primarily by conduction from heaters typically operated between 1000 and 1500oF (540 and 815oC). The heaters are installed in wells at regular intervals within the soil. As the soil is heated, wate...

The aspects of the functioning centralized heating systems residential urban districts after additional insulation this district existing buildings were considered. influence heat carrier temperature in distribution network on transfer surface exchangers that are installed individual station schemes for hot water supplying was analyzed. Estimates made single-stage connection to systems. When de...

Carbon monoxide poisoning has been reported as a result of exposure to various sources of smoke, such as car exhaust fumes, home water heaters and tobacco smoke. We describe a case of symptomatic, moderately severe carbon monoxide (CO) poisoning in a young Mediterranean man after smoking a waterpipe, or shisha. This case highlights the importance of considering carbon monoxide exposure in patie...
