Mathematical Model Establishment for the Multi-Scale Permeability of Coal Reservoirs and Its Engineering Significance

Energies
Permeability is a critical parameter governing the gas flow behavior of the coalbed methane (CBM) reservoir during the exploration and exploitation of CBM, as well as the geological storage of CO2 in the coalbeds. It is strongly associated with the multi-

Impact of positive end expiratory pressure on cerebral hemodynamic in paediatric patients with post-traumatic brain swelling treated by surgical decompression.

PLoS ONE, 2018
IntroductionThe objective of our present study is to evaluate the impact of different PEEP levels on cerebral hemodynamic, gas exchanges and respiratory system mechanics in paediatric patients with post-traumatic brain swelling treated with decompressive

Insights into gas generation and self-absorption in lithium-ion batteries after fast charge aging: Mechanism and implications

Applications in Energy and Combustion Science
Lithium-ion batteries (LIBs) are susceptible to accelerated degradation, swelling, and safety concerns under fast-charging conditions, largely due to gas generation and related side reactions.

Molecular simulation of self-diffusion of CH4, H2O and CO2 in coal macromolecule

Meikuang Anquan
In this paper, the self-diffusion coefficients (SDC) of CH4/CO2/H2O in coal molecules under different ensemble conditions and the effects of temperature and pressure are calculated by grand canonical Monte Carlo and molecular dynamics (MD) methods ...

Etiology, Diagnosis, and Treatment Strategy of Dental Therapy-related Subcutaneous Emphysema

Dental Hypotheses
Subcutaneous emphysema (SE) is defined as localized tissue swelling caused by gas entering subcutaneous tissue through a tissue gap. Although SE is usually a nonfatal and self-limiting disease, in severe cases, the gas may spread to the neck, mediastinum,

Impact of hydroxypropyl guar polymer on rheology and filtration properties of water-based drilling fluids

Petroleum
Water-based drilling muds (WBM) are a very crucial component of the oil and gas industry; however, they often face challenges with inadequate rheological performance and excessive fluid loss. This paper introduces hydroxypropyl guar polymer (HPG) and fly
