Awareness of climate change and the threat of rising energy prices have resulted in increased attention being paid to energy issues, and industry seeing a cost benefit in using more energyefficient production processes. One energy-efficient measure is the recovery of industrial excess heat. However, this option has not been fully investigated and some of the technologies for recovery of excess ...

Our knowledge of the physical events associated with the passage of an action potential along a nerve probably represents the most precise and detailed information available for any biological process. Yet there is an almost complete absence of knowledge of the specific biochemical changes involved or of the energeties of the action currents. Measurement of thermal changes during such activity ...

The energetic cost of activation was measured during an isometric tetanus of white muscle fibres from the dogfish Scyliorhinus canicula. The total heat production by the fibres was taken as a measure of the total energetic cost. This energy consists of two parts. One is due to crossbridge interaction which produces isometric force, and this part varies linearly with the degree of filament overl...

Normal and transformed chick embryo cells and their respective ethidium bromide-treated derivatives that are devoid of a functional respiratory chain were comparatively evaluated for their responses to hyperthermia treatment. No significant difference was found between the control and the respiration-deficient cells. The cells have a similar intrinsic thermosensitivity as judged by their capaci...

Abstract—High penetration of intermittent renewable energy sources (RES) such as solar power and wind power into the energy system has caused temporal and spatial imbalance between electric power supply and demand for some countries and regions. This brings about the critical need for coordinating power production and power exchange for different regions. As compared with the poweronly systems,...

Malignant hyperthermia (MH) is a pharmacogenetic disease which predisposes to the trigger of a life-threatening, hypermetabolic syndrome by potent inhaled anesthetics and by depolarizing skeletal muscle relaxants. Heat production in the anesthetized MH can be profound with 5-fold increases in oxygen consumption. The trigger anesthetics cause an abnormal, sustained rise in myoplasmic calcium lev...

Metabolic processes that release energy within the myocardium can be separated into aerobic metabolism, i.e., chemical reactions consuming O2, and anaerobic metabolism, defined here as chemical reactions not consuming 2, even though 02 may be present in the environment. The total energy that is set free by both types of process appears partially as heat within the myocardium and partially as me...

Heat flow SQ of the First Law of Thermodynamics is expressed in terms of the entropy flow &Q/T) SQ = SIT(QIT)I = ~~(Q/~+(Q~~d~ where T&Q/T) denotes the energy equivalent of the entropy flow, and (Q/T)dT introduces the concept of lost heat into entropy production. Here Q = QK f Q R where superscripts K and R indicate conduction and radiation, respectively. In terms of the lost heat, dimensionles...

The contributions of aerobic and anaerobic muscle metabolism to the heat produced in porcine malignant hyperthermia were studied in seven Pietrain pigs. Oxygen consumption measurements were used to calculate the increase in muscle temperature as a result of aerobic metabolism and this was compared with the observed muscle temperature. The results show that in the initial stage of porcine malign...
