Simulation and Experiment on Elimination for the Bottom-Sitting Adsorption Effect of a Submersible Based on a Submerged Jet

, 2023
When a submersible is sitting on a seabed, it could lose buoyancy because of the bottom-sitting adsorption effect. In this article, a numerical calculation model and experimental scheme for eliminating the bottom-sitting adsorption effect of under-sea ...

Tensile Stimulation in Biorelevant Culture Conditions Enhances MSC and TPSC Tenogenesis on Aligned Electrospun Scaffolds

Advanced NanoBiomed Research, EarlyView.
Biomimetic electrospun scaffold incorporating GDF‐7‐loaded mesoporous silica nanoparticles, combined with mechanical stimulation and physiological oxygen tension, guides tenogenic differentiation of mesenchymal stromal cell and tendon progenitor stem cell. This integrated approach enhances cell proliferation, matrix deposition, and tendon‐specific gene

Atmospheric and submerged bone cement erosion by a pulsating water jet with a straight tubular nozzle extension

Scientific Reports
A pulsating water jet (PWJ) offers advantages over a continuous water jet, such as lower liquid volume flows and pressures for deeper cuts. However, traditional PWJ setups are unsuitable for minimally invasive surgeries due to their size.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Development of Erosion in High-Speed Submerged Water Jets.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1994
High-Speed submerged water jets have two characteristic peaks with respect to the stand-off distance, in the same manner as high-speed water jets in air. In order to clarify the behavior of the impulsive pressures at these two peaks, we systematically carried out erosion tests using an aluminum-alloy specimen in a wide range of the injection pressure ...

Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...
