Parametric analysis on parallel flash cogeneration cycle for enhancing heat source utilization

International Journal of Sustainable Energy
Demand for electricity and cooling is increasing due to population growth, which in turn increases pollution. Renewable energy sources are gaining popularity due to their lower levels of pollution.

Preheating of the early Universe by radiation from high-mass X-ray binaries

, 2016
Using a reliably measured intrinsic (i.e. corrected for absorption effects) present-day luminosity function of high-mass X-ray binaries (HMXBs) in the 0.25-2 keV energy band per unit star-formation rate, we estimate the preheating of the early Universe ...

Power Production from Low Temperature Heat Sources

, 2009
As part of the energy recovery part of the ROMA (Resource Optimization and recovery in the Materials industry) project, a laboratory prototype power production system is being built and completed in 2009. The laboratory prototype is based on a new technology for power production from low to medium temperature heat sources (the off gas from electrolysis

Geodesic acoustic modes in a fluid model of tokamak plasma : the effects of finite beta and collisionality

, 2015
Starting from the Braginskii equations, relevant for the tokamak edge region, a complete set of nonlinear equations for the geodesic acoustic modes (GAM) has been derived which includes collisionality, plasma beta and external sources of particle ...

Hi Spin Temperatures and Heating Requirements in Outer Regions of Disk Galaxies

, 1993
ABSRACT:We show how to use 21-cm emission and absorption studies to estimate the heat inputs to the neutral gas in low pressure environments, such as in outer disks of spiral galaxies, in galactic halos or in intergalactic space.

Heating and cooling of magnetars with accreted envelopes

, 2009
We study the thermal structure and evolution of magnetars as cooling neutron stars with a phenomenological heat source in an internal layer. We focus on the effect of magnetized (B > 10^{14} G) non-accreted and accreted outermost envelopes composed of ...
