Hey, E. N., and O'Connell, B. (1970). Archives of Disease in Childhood, 45, 335. Oxygen consumption and heat balance in the cot-nursed baby. Oxygen consumption and heat balance have been studied in 42 clothed babies under varied environmental temperature conditions. The information obtained has made it possible to compare the thermal environment provided by an incubator with that provided by an...

This article describes the mechanisms affecting the thermal behavior of buildings. This behavior depends upon the temperature and humidity balance in premises. First the physical mechanisms of heat transfer are explained, followed by a description of the heat and humidity sources and sinks in premises. The next three sections deal with the physics of psychrometry, necessary for understanding th...

An attempt is made to determine the role of the ocean in establishing the mean tropical climate and its sensitivity to radiative perturbations. A simple two-box energy balance model is developed that includes ocean heat transports as an interactive component of the tropical climate system. It is found that changes in the zonal mean ocean heat transport can have a considerable affect on the mean...

The objectif of the present work is to determinate the potential of the solar parabolic trough collector (PTC) for use in the design of a solar thermal power plant in Algeria. The study is based on a mathematical modeling of the PTC. Heat balance has been established respectively on the heat transfer fluid (HTF), the absorber tube and the glass envelop using the principle of energy conservation...

Independent measurements of the major energy balance flux components are not often consistent with the principle of conservation of energy. This is referred to as a lack of closure of the surface energy balance. Most results in the literature have shown the sum of sensible and latent heat fluxes measured by eddy covariance to be less than the difference between net radiation and soil heat fluxe...

metric (mapping evapotranspiration at high resolution with internalized calibration) is known as an appropriate surface energy balance model for the estimation of the spatial distribution of evapotranspiration (et) in semi-arid regions. based on lysimeter measurements, metric has shown et estimates of 10% on a sub-field scale on a daily basis. there is a need to identify how the model is sensit...

Recent revised estimates of the Earth's surface heat flux are in the order of 47 TW. Given that its internal radiogenic (mantle and crust) heat production is estimated to be around 20 TW, the Earth has a thermal deficit of around 27 TW. This article will try to show that the action of the gravitational field of the Sun on the rotating masses of the Earth is probably the source of another heat p...

The heat balance under electrolysis in 1M Li2SO4 light water solutions was measured using Pd rods or Pd coated Ni (Pd/Ni) rods for cathode. We detected large excess heat of more than 10% in 6 of 28 experiments. However, in many other experiments, no excess or only small excess heat was observed. In most cases the excess heat was 5% or less. In order to confirm the excess heat, we have to find t...
