ACS Omega, 2022 The gas content and permeability of the coal reservoir are the key factors affecting coalbed methane (CBM) productivity. To investigate the geological controls on the permeability and gas content of coal reservoirs in the Daning block, southern Qinshui ...

Energies, 2021 This study is predominantly about the differences in shale pore structure and the controlling factors of shale gas content between Lower Silurian and Lower Cambrian from the upper Yangtze plate, which are of great significance to the occurrence mechanism

Geofluids, 2022 In the process of coalbed methane development, the gas content not only determines the reserves of methane in coal reservoir but also is the most important geological parameter affecting the production of coalbed methane.

Geofluids, 2021 The accurate calculation of the gas content of coalbed bed methane (CBM) reservoirs is of great significance. However, due to the weak correlation between the logging response of coalbed methane reservoirs and the gas content parameters and strong ...

The High Molecular Gas Content, and the Efficient Conversion of Neutral into Molecular Gas, in Jellyfish Galaxies [PDF]
Astrophysical Journal, 2020 In the disks of four jellyfish galaxies from the GASP sample at redshift ∼0.05 we detect molecular gas masses systematically higher than in field galaxies.

Gas Content Regulates the Life Cycle of Star Formation and Black Hole Accretion in Galaxies [PDF]
Astrophysical Journal, 2020 Feedback from active galactic nuclei (AGNs) is expected to impact the amount of cold gas in galaxies by driving strong galactic winds, by preventing external gas inflows, or by changing the thermodynamical state of the gas.

The evolution of the dust and gas content in galaxies [PDF]
Astronomy & Astrophysics, 2014 We use deep Herschel PACS and SPIRE observations in GOODSS, GOODSN and COSMOS to estimate the average dust mass (Mdust) of galaxies on a redshift-stellar mass (Mstar)-SFR grid. We study the scaling relations between Mdust, Mstar and SFR at z<=2.5. No clear evolution of Mdust is observed at fixed SFR and Mstar. We find a tight correlation between SFR

Automatic Measurement Device of Gas Desorption Data in Laboratory
Meikuang Anquan, 2020 The method of direct volume measurement via drainage is often applied in the process of measuring gas desorption in laboratory, but there are many problems such as too many people involved, large error in reading and complicated measurement process. The

Gas Flows and Gas Contents in Globular Clusters [PDF]
Progress of Theoretical Physics, 1979 The flow of gas injected from stars in globular clusters is numerically studied by means of the time-dependent beam scheme. By using structural parameters derived by Peterson and King (1975) and taking radiative cooling and ultraviolet heating into account, we obtain the time variation of velocity, temperature and density distributions in the gas flows

Molecular gas content of H i monsters and implications to cold gas content evolution in galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We present 12CO (J=1-0) observations of a sample of local galaxies (0.043e10Msun from the ALFALFA survey and 8 LSBs with a comparable M(HI) (>1.5e10Msun). Our sample selection is purely based on the amount of neutral hydrogen, thereby providing a chance to study how atomic and molecular gas relate to each other in these HI-massive systems.
