Some mammals have the ability to lower their hypothalamic temperature below that of carotid arterial blood temperature, a process termed selective brain cooling. Although the requisite anatomical structure that facilitates this physiological process, the carotid rete, is present in members of the Cetartiodactyla, Felidae and Canidae, the carotid rete is particularly well developed in the artiod...

We compare the recent temperature estimate for Geminga with neutron star cooling models. Because of its age (∼ 3.4 × 10 yr), Geminga is in the photon cooling era. We show that its surface temperature (∼ 5.2× 10 K) can be understood by both types of neutrino cooling scenarios, i.e, slow neutrino cooling by the modified Urca process or fast neutrino cooling by the direct Urca process or by some e...

The theory of available potential energy applied to a “translating” atmospheric volume is used to estimate the generation of available potential energy for the cyclogenetic, mature, and occluding stages of a mid-latitude cyclone. Primary attention is focused upon the importance of the diabatic process of latent heat release in generating the storm’s available potential energy. In addition, prel...

A quantification model of transient heat conduction was provided to simulate apple fruit temperature distribution in the cooling process. The model was based on the energy variation of apple fruit of different points. It took into account, heat exchange of representative elemental volume, metabolism heat and external heat. The following conclusions could be obtained: first, the quantification m...

The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In this paper we compute accurate cooling sequences for carbon–oxygen white dwarfs with hydrogen dominated atmospheres for the full range of masses of interest. For this purpose we use the most accurate available physica...
