An analytical investigation of critical factors to prioritize coalfields for Underground Coal Gasification – Bangladesh case

Heliyon, 2023
In recent decades, many countries have shown a growing interest in Underground Coal Gasification (UCG) as a potential clean and environmental-friendly means of harnessing coal energy for power generation, and production of hydrogen, diesel fuel, etc ...

Correlated Hybrid Fluctuations from Inflation with Thermal Dissipation

, 2003
We investigate the primordial scalar perturbations in the thermal dissipative inflation where the radiation component (thermal bath) persists and the density fluctuations are thermally originated.

Chemical potential of liquids and mixtures via Adaptive Resolution Simulation [PDF]

, 2014
We employ the adaptive resolution approach AdResS, in its recently developed Grand Canonical-like version (GC-AdResS) [Wang et al. Phys.Rev.X 3, 011018 (2013)], to calculate the excess chemical potential, $\mu^{ex}$, of various liquids and mixtures.

Energy-Momentum Tensor of Cosmological Fluctuations during Inflation

, 2003
We study the renormalized energy-momentum tensor (EMT) of cosmological scalar fluctuations during the slow-rollover regime for chaotic inflation with a quadratic potential and find that it is characterized by a negative energy density which grows during ...
