Predictors for New Native-Vessel Occlusion in Patients with Prior Coronary Bypass Surgery: A Single-Center Retrospective Research

Objectives.Chronic total occlusion (CTO) is prevalent Trousers in patients with prior coronary artery bypass grafting (CABG).However, data available concerning the prevalence of new-onset CTO of native vessels in patients with prior CABG is limited.Therefore, the objective of the study is to determine predictors for new native-vessel occlusion in p

The influence of moisture content on coal deformation and coal permeability during coalbed methane (CBM) production in wet reservoirs

Abstract Moisture adsorption in the coal seams affects the gas adsorption capacity and can alter the coal deformation and permeability criteria of the coal seam.The effect of dynamic loss of moisture content, both on moisture and gas sorption-induced coal swelling/shrinkage strains, during the coalbed methane (CBM) production, is crucial.This study
