Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Impact of Ceiling Suspended Shield Size on Primary Operator Radiation Dose During Coronary Angiography and Intervention

Journal of Medical Radiation Sciences, EarlyView.
Reducing radiation exposure to staff performing coronary angiography and intervention is an occupational health and safety priority for hospitals. We demonstrate that a larger lead acrylic shield, with lead rubber pleats on the lower edge will reduce radiation exposure to the cardiologist performing the procedure by approximately 40%. We recommend that
