BACKGROUND: The N95 filtering facepiece respirator (FFR) is the most popular individual
protective device to reduce exposure to particulate matter. However, concerns have been …

Abrasive waterjet (AWJ) systems represent an emerging technology for hard rock cutting in
urban underground spaces, offering low vibration and precise cutting performance. However, …

The abrasive mixing variables, such as the abrasive and water flow rates and the focus
geometry parameters, determine the profitability of an abrasive waterjet system. In this study, the …

In submerged floating tunnels (SFTs), a next-generation maritime transportation infrastructure,
the tunnel module floats in water due to buoyancy. For the effective and economical use of …

We describe the rare experience of veno–veno–arterial (VVA) extracorporeal membrane
oxygenation (ECMO) in a patient with acute respiratory distress syndrome and septic-induced …

Abrasive waterjet (AWJ) is a technology that removes a target material with an abrasive
accelerated by ultra-high-pressure water. Recently, its application for rock excavations in civil …

The high-level nuclear waste repository is a deep geological disposal system exposed to
complex environmental conditions such as high temperature, radiation, and groundwater due …

This study aimed to understand how standoff distance and abrasive flow rate affect material
removal when using abrasive waterjet drilling. At the same exposure time of 60 seconds, the …

The high-Level Nuclear Waste (HLW) Repository has complex stresses such as high
temperature, humidity, and radiation. And these stresses cause deterioration and cracks in the …

The rock excavation method using abrasive waterjet technology has the advantage of low
noise and low vibration during construction, so various studies have been conducted to apply …
