In this paper, we develop a mathematical model of sprinting in which anaerobicmetabolism is included. This model is simplified by considering the broad changes of energy leveland the cyclic variation associated with the strike pattern. We consider the effect of the centre of massto the overall energy balance along with force of resistance during initial motion of body. Results areobtained for t...

The most important meteorological parameter affecting the human energy balance during sunny weather conditions is the mean radiant temperature T(mrt). It considers the uniform temperature of a surrounding surface giving off blackbody radiation, which results in the same energy gain of a human body given the prevailing radiation fluxes. This energy gain usually varies considerably in open space ...

We give arguments for the existence of exact travelling-wave (in particular solitonic) solutions of a perturbed sine-Gordon equation on the real line or on the circle, and classify them. The perturbation of the equation consists of a constant forcing term and a linear dissipative term. Such solutions are allowed exactly by the energy balance of these terms, and can be observed experimentally e....

Supraglacial ponds on debris-covered glaciers present a mechanism of atmosphere/glacier energy transfer that is poorly studied, and only conceptually included in mass-balance studies of debriscovered glaciers. This research advances previous efforts to develop a model of mass and energy balance for supraglacial ponds by applying a free-convection approach to account for energy exchanges at the ...

Current changes in the tropical hydrological cycle, including water vapour and precipitation, are presented over the period 1979-2008 based on a diverse suite of observational datasets and atmosphere-only climate models. Models capture the observed variability in tropical moisture while reanalyses cannot. Observed variability in precipitation is highly dependent upon the satellite instruments e...

This paper investigates the two-dimensional rolling motion of a single large particle in a shallow water stream down a steep rough bed from both an experimental and a theoretical point of view. The experiment is prototypal of sediment transport on sloping beds. Two theoretical models are presented. The first model uses the mean kinetic energy balance to deduce the average particle velocity and ...

The determination of the calorific value of the material stored in or lost from the body during an interval of time can be made in two ways: by the comparative slaughter method and by the balance method. In the comparative slaughter method at the beginning and at the end of the time interval the heats of combustion of the entire bodies of two precisely similar animals are determined, and the re...
