Experimental results of the thermal conductivity (k(T)) of nanostructured g-As2S3 during cooling and heating processes within the temperature range from 2.5 to 100 K have been analysed. The paper has considered thermal conductivity is weakly temperature k(T) dependent from 2.5 to 100 K showing a plateau in region from 3.6 to 10.7 K during both cooling and heating regimes. This paper is the firs...

Self-heating phenomena are studied from room down to near liquid helium temperatures in fully depleted N channel thin film SIMOX MOS devices. A simple theoretical analysis of the self-heating effect is worked out. A method for the extraction of the thermal resistance and the device temperature rise directly from the static output characteristics is derived. Also direct self heating transient me...

In this paper we calculate the turbulent heating rates in the solar wind using the Kolmogorov-like MHD turbulence phenomenology with Kolmogorov’s constants calculated by Verma and Bhattacharjee [1995b,c]. We find that the turbulent heating can not account for the total heating of the nonAlfvénic streams in the solar wind. We show that dissipation due to thermal conduction is also a potential he...

To investigate the effects of local density fluctuations on phonon propagation in a hydrogen bonded structure, we studied the thermal conductivity κ of the crystal, liquid, and glassy states of pure glycerol as a function of the temperature, T, and the pressure, p. We find that the following: (i) κcrystal is 3.6-times the κliquid value at 140 K at 0.1 MPa and 2.2-times at 290 K, and it varies w...

introduction: canning is the most effective way to food preservation. starch- based foods include the major food materials such as porridges. these foods due to sensitivity to high shear rates used in rotary retorts and thus texture decomposition, usually sterilized in static retorts. broken heating behavior, can headspace and initial temperature have important role on heat transfer rate and th...

ABSTRACT: Mustard is a natural multi-functional additive with strong hot flavor. In this research, powdered yellow mustard (Sinapis alba) was heated by 21 different thermal processes, statistically designed by Response Surface Methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

In this paper is presented an analysis method of electrical circuits, more exactly nodal method, in order to compute the temperature field distribution necessary to the heating and ventilation systems of electrical machine. As analysis method, the modified nodal method was used which does not impose any restriction at the circuit structure, being a prevalence of the nodal method. For this reaso...

This paper reviews existing studies and investigates thermal operational regimes of diamond bit during drilling operations. The operating temperature of the diamond core drill is studied under bench condition and an optimal thermal range are presented. Based on this study, it was noted that glazing of diamond tools is observed at temperatures less than 327°C, and normal wear of diamond tools is...
