the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

The performance of a hybrid electric vehicle (HEV) depends strongly on the performance of its high-voltage battery pack, which is influenced by temperature. We have been working on thermal management of batteries in HEVs, including cooling and heating issues. In cold temperatures, batteries perform poorly because of high internal resistance; the vehicle may start slowly. The battery may need to...

In this paper, the effect of Polypropylene Fibers added to concrete on strength and thermal resistance of high strength concrete has been investigated. Therefore, five tests have been carried out to reach this goal which it includes; effect of weight percent of polypropylene fibers on mechanical properties of concrete, effect of fiber’s length on the strength of high strength concrete, effect o...

[1] The one-dimensional model of Rudnicki and Chen [1988] for a slip-weakening dilating fault is extended to include shear heating. Because inertia is not included, instability (a seismic event) corresponds to an unbounded slip rate. Shear heating tends to increase pore pressure and decrease the effective compressive stress and the resistance to slip and consequently tends to promote instabilit...
