Prediction of Geopolymer Concrete Compressive Strength Utilizing Artificial Neural Network and Nondestructive Testing

Civil and Environmental Engineering, 2022
A promising substitute for regular concrete is geopolymer concrete. Engineering mechanical parameters of geopolymer concrete, including compressive strength, are frequently measured in the laboratory or in-situ via experimental destructive tests, which ...

‘When joy comes your way, you have to grab it!’ Troubling how queer joy features in the lives of LGBT+ school‐attending youth in South Africa

British Educational Research Journal, EarlyView.
Abstract Recently, the concept ‘queer joy’ has gained interest in LGBT+ scholarship in the West. I use this scholarship as an entry point to explore how school‐attending LGBT+ youth express joy and how joy serves as a form of resistance against gender and sexuality norms in educational settings.

Research on the Rebound Hammer Testing of High-Strength Concrete’s Compressive Strength in the Xinjiang Region

Buildings, 2023
Enhancing the assessment of compressive strength and the efficiency of rebound hammers in non-destructive testing for high-strength concrete is an urgent issue in construction engineering. This study involved C50 to C90 high-strength concrete specimens, utilizing rebound hammers with nominal energies of 4.5 J and 5.5 J, along with a compression machine.

Between soft power and suspicion: Chinese international students as diasporic actors in U.S.‐China geopolitical tensions

British Educational Research Journal, EarlyView.
Abstract This study examines the under‐theorized political role and identity of Chinese international students, who emerge as significant actors caught between U.S. soft power ambitions and rising geopolitical suspicion. Amid escalating U.S.‐China tensions, these students are forced to confront environments shaped by competing geopolitical discourses ...
