Experiments on the Rock Electricity and Application Research considering the Influence of CO2 Content: A Case Study of the Dongfang 13 Gas Field

open access: yesLithosphere, 2022
A large number of CO2-bearing gas layers are distributed in the deep layers in the Huangliu and Meishan formations of the Dongfang 13 gas field. The presence of CH4, CO2, and formation water in CO2-bearing gas layers complicates the change of logging ...

Analysis of Natural Hydraulic Fracture Risk of Mudstone Cap Rocks in XD Block of Central Depression in Yinggehai Basin, South China Sea

open access: yesEnergies, 2021
The Yinggehai Basin is an important Cenozoic gas bearing basin in the South China Sea. With the gradual improvement of gas exploration and over-development in shallow layers, deep overpressured layers have become the main target for natural gas ...

Production of Transgenic Cloned Miniature Pigs with Membrane-bound Human Fas Ligand (FasL) by Somatic Cell Nuclear Transfer [PDF]

open access: yes, 2010
Cell-mediated xenograft rejection, including NK cells and CD8+ CTL, is a major obstacle in successful pig-to-human xenotransplantation. Human CD8+ CTL and NK cells display high cytotoxicity for pig cells, mediated at least in part by the Fas/FasL pathway.

Differences in the key volatile organic compound species between their emitted and ambient concentrations in ozone formation [PDF]

open access: yesAtmospheric Chemistry and Physics
The emissions and secondary transformations of volatile organic compounds (VOCs) play a significant role in ozone (O3) formation. Previous studies have often relied on ambient VOC concentrations to identify key species.
