Hydrodynamic Ram Effect Caused by Debris Hypervelocity Impact on Satellite Tank

Applied Sciences, 2019
To study the hydrodynamic ram effect caused by the debris hypervelocity impact on the satellite tank, a numerical simulation of the spherical debris impacting the satellite tank at the velocity of 7000 m/s was carried out based on ANSYS/LS-DYNA software.

Short‐term actions of epigalocatechin‐3‐gallate in the liver: a mechanistic insight into hypoglycemic and potential toxic effects

FEBS Open Bio, EarlyView.
Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...

Tracking the 6-DOF Flight Trajectory of Windborne Debris Using Stereophotogrammetry

Infrastructures, 2019
Numerous post-windstorm investigations have reported that windborne debris can cause costly damage to the envelope of buildings in urban areas under strong winds (e.g., during hurricanes or tornados).

Silica-Rich Bright Debris Disk around HD 15407A

, 2012
We report an intriguing debris disk towards the F3V star HD 15407A, in which an extremely large amount of warm fine dust (~ 10^(-7) M_Earth) is detected. The dust temperature is derived as ~ 500-600 K and the location of the debris dust is estimated as 0.

Calcium‐sensing receptor induces the apoptosis of chondrocytes in cooperation with phosphate transporter

FEBS Open Bio, EarlyView.
Excess Ca2+ ions activate the Calcium‐Sensing Receptor (CaSR), which subsequently drives the uptake of excess inorganic phosphate (Pi) via the Pi transporter (Pit−1) in chondrocytes. This mechanism causes a toxic increase in intracellular Pi concentration, ultimately leading to chondrocyte apoptosis and pathological mineralization. Excess extracellular

Monte Carlo simulation of delayed γ-rays ionizing the atmosphere based on debris motion model

He jishu
BackgroundIn the aftermath of a high-altitude nuclear explosion, the delayed γ-rays emanating from the debris undergo a complex ionization process while traversing the non-uniform high-altitude atmosphere.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Aerial Remote Sensing of Aquatic Microplastic Pollution: The State of the Science and How to Move It Forward

Microplastics
Microplastics (MPs) are pervasive environmental contaminants in aquatic systems. Due to their small size, they can be ingested by aquatic biota, and numerous negative effects have been documented.
