Pressure Fluctuations in the S-Shaped Region of a Reversible Pump-Turbine
Numerical simulations were performed to investigate pressure fluctuations in the S-shaped region of a pump-turbine model. Analyses focused on pressure fluctuations in the draft tube and in the gap between the guide vanes and runner.

Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

This study investigates the potential for reducing emissions during the sintering process by selectively adjusting the O2, CO, and H2O content in the recirculation gas. Adjusting these components positively affects the sintering process, enabling the coke breeze content in the sinter mixture to be reduced.

ABSTRACT This article examines the militarization of white settler women during the Kenya Emergency (1952–1960), analyzing how their armed participation disrupted and reconfigured colonial gender norms. Drawing on visual and textual archival and newspaper sources, this article explores representations of settler women as maternal guardians of the ...

Torsional vibrations at guide-vane shaft of pump-turbine model [PDF]
This article focuses on the problem of guide-vane vibrations of reversible pump-turbines, especially, in the pump mode. These vibrations are transmitted to the guide-vane shaft torque. The guide-vane vibrations are caused by the impeller exit flow, which

Analysis of Rotor-Stator Interaction in Turbine Mode of a Pump-Turbine Model
The highest-level fluctuations in large pump-turbines are usually originated from rotor-stator interaction (RSI) in the vaneless region. Hence, the studies of RSI phenomenon and corresponding unsteady effects are significantly important to reduce the ...

Small Object Detection Method for Bioimages Based on Improved YOLOv8n Model
This study proposes a small object detection method for bioimages based on an improved YOLOv8n model. Experimental results demonstrate that the proposed approach effectively enhances detection precision, recall, and mAP50, offering a novel solution for the technical challenges in biological microscopy research.
