Using concrete as a thermal energy storage (TES) material is a promising option for large-scale solar-thermal resource development and utilization. Specific heat is one of the most important characteristics for TES performance. In this paper, the half-open dynamic method based on the mixing principle is proposed and applied to measure concrete-specific heat at temperatures up to 600 ◦C. Measure...

Flat tube heat exchangers with louvered fins were applied in order to meet the performance requirements and compactness in automotive air conditioning systems. Experimental and simulation study focusing on the air side thermal hydraulic performance of automotive heat exchangers were performed in this article. Test results showed that the heat capacity of a condenser with 5.4 mm height louvered ...

Background: The Heat shock proteins are stress induced and there is increased evidence of presence of these chaperons extracellular which is considered to be intracellular. Their present cytokine like effect and help in immune recognition, thus indicate strong extracellular action of heat shock protein 70 in maintaining integrity of oral cavity. Hypothesis: The aim of this study was to evaluate...

Experiments were conducted to determine the influence of local vapor quality on local heat transfer coefficient in flow boiling in an array of microchannels. Additionally, the variation of local heat transfer coefficient along the length and width of the microchannel heat sink for given operating conditions was investigated over a range of flow parameters. Each test piece includes a silicon par...

Bending property of Ti-Ni alloy dental castings was evaluated in comparison with that of Co-Cr alloy in a cantilever test. Heat treatment effect on the bending property was also investigated in relation to phase transformation. Ti-50.85Ni (mol%) alloy was used, and the shape of bending test specimens was half-rounded in cross section, 2.0mm in diameter. The bending test was carried out at 310K....

cus aureus by heat shock. The effect has then been more thoroughly investigated by landolo and Ordal (5, 6). Since heat shock causes an increased sensitivity of fungal cells to high temperature and blue light (2-4), it seemed justified also to test the response of heat-shocked fungal cells to high concentrations of sodium chloride. Most experiments were performed with the ascomycete Ophiostoma ...
