The temperature gradient at the screw root indicated that an energy flux in through the screw was occurring.
In order to address this question, we are modeling thermal energy flux in both male and female crabs of different species that have varying degrees of sexual dimorphism.
The results demonstrate: (1) conversion of excess excitation energy into heat, called thermal dissipation, limits energy flux through photosystem (PS) II during development of PS II, (2) following development of maximum electron-transport potential within PS II, thermal dissipation decreases allowing for increased photochemical utilization of excitation energy, and (3) changes of the magnitude of thermal dissipation help maintain an optimal, manageable energy flux through the photosystems during the development of photochemistry.
where y = observed energy flux; [micro] = actual mean energy flux; [alpha] = effect of temperature; [epsilon] = experimental error; i = individual test index.
Theoretical Considerations: Energy Flux At The Fermi Surface
The scientists' main interest is the energy flux, or transfer of energy, that occurs between the ocean and atmosphere.
This paper summarizes the eddy covariance measurements of net C[O.sub.2], [H.sub.2]O vapor, and energy flux from a moist-tussock tundra ecosystem during the 1994-1995 summer growing seasons.
To estimate latent and sensible heat fluxes (LE, H), Bowen-ratio surface energy flux systems were installed shortly after the fall soybean harvest which generally occurred around mid-October.
The effectiveness of such models depends on their ability to include the role of clouds, which play a major role in regulating energy flux in the atmosphere by reflecting incoming solar radiation and trapping up-welling infrared radiation.
Thus thermal diffusivity is the parameter relating energy flux to energy gradient, whereas conductivity relates the energy flux to the temperature gradient.
Therefore, an in-depth study of energy flux partitioning and evapotranspiration in a desert riparian P.
We also note the dependence of the energy density and the energy flux on the reference frame.
