A COMPARISON OF TESTING METHODS FOR DETERMINATION OF SPRAYED CONCRETE TENSILE STRENGTH

Acta Polytechnica CTU Proceedings, 2019
Sprayed concrete is important construction material in tunnelling. Primary lining is essential in NATM where the sprayed concrete can be loaded by tension due to bending moments.

Imprint of Indian Ocean Dipole on nitrous oxide dynamics

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract The northern Indian Ocean is a hotspot of nitrous oxide (N2O) emissions, with strong seasonal monsoons and interannual Indian Ocean Dipole (IOD) variability. We examine the IOD influence on N2O seasonality using a regional ocean model covering 1981–2020, with a focus on the coastal ocean where ∆pN2O variability is more than threefold greater ...

On the Classification of Vehicle Cut‐In Scenarios Severity: Empirical Evidence to Validate the Severity Classification of UN R157

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study validates the Fuzzy Safety Model (FSM) as a tool for classifying the difficulty of vehicle cut‐in scenarios, supporting its role in Automated Lane Keeping Systems (ALKS) safety assessments. Results from a test campaign demonstrate the FSM's effectiveness in categorising preventable cases and its broader applicability in enhancing automated ...

Multifield Coupling Mechanisms and Support Strategy for Creep–Seepage Interaction in Water‐Bearing Argillaceous Soft Rock Tunnels

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Water‐bearing argillaceous soft rock, characterized by high porosity, low bearing capacity, and water sensitivity, is prone to instability under creep–seepage coupling effects in tunnel engineering, threatening construction safety. This study investigates the soft rock of a water conveyance tunnel in Henan Province, China.

Bullous Systemic Lupus Erythematosus: Clinical Presentation in Two Asian Cases

Case Reports in Medicine, Volume 2026, Issue 1, 2026.
Bullous systemic lupus erythematosus (BSLE) is a rare subset of systemic lupus erythematosus (SLE), characterized by the rapid onset of vesiculobullous lesions that primarily affect sun‐exposed areas of the body. These lesions typically form along the dermal–epidermal junction and are associated with the presence of autoantibodies that target the skin.

Mini‐Open‐Assisted Screw Fixation for Displaced Intra‐Articular Calcaneus Fractures: Three Case Reports of Patients With Good Postoperative Outcomes

Case Reports in Orthopedics, Volume 2026, Issue 1, 2026.
Displaced intra‐articular calcaneus fractures (DIACFs) are debilitating injuries often resulting from a fall from height or motor vehicle accidents. Traditional fixation methods involve extended incisions that can lead to soft tissue breakdown or necrosis.
