ABSTRACT Purpose Short periods of reduced energy availability are commonly undertaken by athletes to decrease body mass, possibly improve the power-to-mass ratio, and enhance physical performance. Our primary aim was to investigate the impact of 10 d of low energy availability (LEA) followed by 2 d of optimal energy ...

A Timetable for Expanded Energy Availability
Science, 1974Energy availability depends upon technical potential of a technology or a resource or whether the estimate also assumes favorable economic conditions and a new political consensus. Continued high prices for oil, coal and natural gaa seem inevitable. Domestic production of all fossil fuel is lagging.

SynopsisThe present buyer's market in energy is likely to continue for several years, but in the longer run the disparity in resources and consumption rates among the principal fuels will result in renewed shortage and price rises for oil and natural gas.

Availability and Available Energy
1981We recall that a thermodynamic property is defined as any quantity that depends on the state of a system but is independent of any path or process by which the system arrived at a given state. If a system undergoes a cycle, then the change in the value of all properties of the system is zero during this operation, that is $$\oint {dP = 0 ...

Modeling energy availability in RF Energy Harvesting Networks
2016 International Symposium on Wireless Communication Systems (ISWCS), 2016In a Radio Frequency (RF) Energy Harvesting Network (RF-EHN) the nodes have the capability of converting received electromagnetic RF signals in energy. Traditionally, the RF signals are provided by high power transmitters operating in the neighborhood of the harvesters.

Abstract Internal energy can be pictured as the energy contained by quiescent matter because of particle motion—the thermal energy—and because of particle interaction—the chemical energy. Attempts to separate these two parts thus far have yielded only qualitative discussions with no logical formulations.

Handedness in man: The energy availability hypothesis
Medical Hypotheses, 2016More than 90% of the human species are right handed. Although outwardly our body appears symmetrical, a 50/50% lateralization in handedness never occurs. Neither have we seen more than 50% left handedness in any subset of the human population. By 12-15weeks of intrauterine life, as many as 6 times more fetuses are noted by ultrasound studies to be ...

Energy Management System for an Energy District With Demand Response Availability
IEEE Transactions on Smart Grid, 2014During recent years the electricity supply chain (electricity production, consumption, distribution, storage, and load management) has changed. In this context a new term appears: the prosumer, that is both a consumer and producer of energy in the same entity.

The concept of available energy
Chemical Engineering Science, 1961Abstract The primary objectives of this paper are: 1. To present an available energy balance reflecting the Second Law of Thermodynamics to complement the macroscopic balances of Bird which are dictated by conservation of mass, the laws of motion and the First Law of Thermodynamics. 2.

Background information on the nature of solar energy impinging upon the earth’s atmosphere is presented. The attenuation of solar radiation by the earth’s atmosphere and the daily, seasonal and geographical variations are discussed. The determination of the amount of solar energy incident on the earth’s surface is described.
