Evolution of Bed Shear Stress in Open-Channel Flow at Smooth-to-Rough and Rough-to-Smooth Transitions

Abstract The evolution of bed shear stress in open-channel flows due to a sudden change in bed roughness was investigated for rough-to-smooth (RTS) and smooth-to-rough (STR) transitions. The velocity field was measured in the longitudinal–vertical plane at high spatial resolution...

Tramadol Co‐Administration with Oxycodone or Hydrocodone Increases Opioid Burden without Improving Postoperative Pain Control

Tramadol is frequently co-prescribed with oxycodone or hydrocodone after surgery under the assumption that its dual mechanism of action provides an opioid-sparing benefit. However, evidence supporting this practice is limited and inconsistent. We conducted a secondary analysis of...

Methane Emissions From Wildfires: Trends and Anomalies

Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass bur...
