Chemical Profiling, Pharmacological Activities, and Toxicity Assessment of Juniperus phoenicea sp. turbinata L. Extract: Integrated In Vitro, In Vivo, and In Silico Insights

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Hydroethanolic leaf and fruit extracts of Juniperus phoenicea showed high phenolic content, dominated by ferulic acid. Both extracts were non‐toxic and exhibited strong anti‐inflammatory, analgesic, antioxidant, and antimicrobial activities. Molecular docking confirmed stable binding to key inflammatory and microbial targets, supporting its ...

Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re‐entry rates, emitting pollutants throughout the atmosphere. The environmental impact of SMCs lacks characterization to determine the need for regulation. We utilize a global 3D emission inventory of recent (2020–2022) space activity that distinguishes SMC ...

Large eddy simulation of a T-Junction with upstream elbow: The role of Dean vortices in thermal fatigue

open access: yesApplied Thermal Engineering, 2016
Turbulent mixing of fluids in a T-Junction can generate oscillating thermal stresses in pipe walls, which may lead to high cycle thermal fatigue. This thermal stripping problem is an important safety issue in nuclear plant thermal-hydraulic systems, since it can lead to unexpected failure of the pipe material. Here, we carry out a large eddy simulation

TS - Dean interactions in curved channel flow

open access: yes, 1990
A weakly nonlinear theory is developed to study the interaction of TS waves and Dean vortices in curved channel flow. The prediction obtained from the theory agree well with results obtained from direct numerical simulations of curved channel flow ...
