Effect of Pretreatment on the Physical Properties and Heating Values of Briquettes [PDF]
Journal of Renewable Energy and Environment, 2023 Briquettes from agro-residues have been promoted as a better replacement to firewood and charcoals for heating and cooking in the rural communities. In view of this, a study was carried out to investigate the effect of pretreatment methods on physical ...

Stability of radiation-pressure dominated disks. I. The dispersion relation for a delayed heating alpha-viscosity prescription [PDF]
, 2011 We derive and investigate the dispersion relation for accretion disks with retarded or advanced heating. We follow the alpha-prescription but allow for a time offset (\tau) between heating and pressure perturbations, as well as for a diminished response ...

Parametric study on the heating values of products as via steam gasification of palm waste using CaO as sorbent material [PDF]
, 2016 In Malaysia, due to abundance of oil palm waste, it is a good candidate to be used as a feedstock for syngas and hydrogen production. Biomass steam gasification is one of the promising methods for syngas production.

Work and heat value of bound entanglement [PDF]
Quantum Information Processing, 2019 Entanglement has recently been recognized as an energy resource which can outperform classical resources if decoherence is relatively low. Multi-atom entangled states can mutate irreversibly to so called bound entangled (BE) states under noise. Resource value of BE states in information applications has been under critical study and a few cases where ...
