Thermally-induced changes in heart rate and blood flow in reptiles are believed to be of selective advantage by allowing animal to exert some control over rates of heating and cooling. This notion has become one of the principal paradigms in reptilian thermal physiology. However, the functional significance of changes in heart rate is unclear, because the effect of heart rate and blood flow on ...

Analytic and Numerical Studies of a Tectonics Model for Solar Coronal Heating Chung-Sang Ng1, A. Bhattacharjee1 1University of New Hampshire. Presentation Number: 14.04 Recent observations have shown that the solar surface is covered with a so-called “magnetic carpet”, in which small-scale magnetic flux loops are continually emerging and interacting. The magnetic flux at the photosphere is thus...

[1] This study examines the effects of cloud-radiative heating on convectively coupled equatorial waves simulated by the Seoul National University (SNU) atmospheric general circulation model (AGCM). The strength of cloud-radiative heating is adjusted by modifying the autoconversion rate needed for cloud condensates to grow up to raindrops. The results show that increasing the autoconversion rat...

A microwave heating system equipped with a proportional–integral–differential (PID) control device was developed for in-package pasteurization of ready-to-eat meats. Frankfurters, inoculated and vacuum-sealed in plastic packages, were subjected to microwave or water immersion heating, with the package surface temperature increased to and maintained at 65, 75, or 85 C, for different periods of t...

In the present study, the dissolution and precipitation behaviour of four different aluminium alloys (EN AW-6005A, EN AW-6082, EN AW-6016, and EN AW-6181) in four different initial heat treatment conditions (T4, T6, overaged, and soft annealed) was investigated during heating in a wide dynamic range. Differential scanning calorimetry (DSC) was used to record heating curves between 20 and 600 °C...

Heating rate during crystallization is known to affect the final texture obtained in lead zirconate titanate thin films. The transient/intermediate phases present in the thin film during perovskite phase nucleation have been suggested to cause this variation in texture with heating rate. To understand the interrelationship between the transient/intermediate phases and the texture in the final p...

Oxygen release from metal oxides at high temperatures is relevant to many thermally activated chemical processes, including chemical-looping combustion, solar thermochemical cycles and energetic thermite reactions. In this study, we evaluated the thermal decomposition of nanosized metal oxides under rapid heating (~10(5) K s(-1)) with time-resolved mass spectrometry. We found that the effective...

A slow pyrolysis of pinewood was investigated in this paper. Through the briquette process, the pinewood sawdust becomes molded biomass. The molded bio-char was produced from molded biomass with different pyrolysis factors, and the bio-char’s heating value, char yield rates, and physicochemical and morphological properties were investigated. Molded bio-char’s characteristics depended principall...
