The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Bond strength of lap spliced steel bars in RC beams strengthened with low-cost natural FRP composites: Experimental and theoretical study

Case Studies in Construction Materials
Natural FRPs have proven their prospective in enhancing the compressive behavior of concrete. However, their effectiveness in preventing brittle steel lap splice failure has not been investigated. This study utilizes low-cost hemp and cotton eco-friendly

The choice to submit: freedom, gender, and the figure of God in Pentecostal Nigeria Le choix de se soumettre : liberté, genre et figure divine chez les Pentecôtistes du Nigeria

Journal of the Royal Anthropological Institute, EarlyView.
Why do some women choose to submit to their husbands in marriage? In anthropology, the paradox of ‘chosen submission’ has famously been explored by Saba Mahmood. Her work amongst Egyptian women donning the veil in the Islamic da'wa movement spotlights the notion of ‘piety’ to explore how devotion to God can act as a powerful motivator of human ...

Evaluating the Splice Effect on the Flexural Performance of RC Beams Reinforced with Hybrid and GFRP Rebars

International Journal of Concrete Structures and Materials
Lap splices play a critical role in the flexural performance of reinforced concrete (RC) members, particularly when non-ductile reinforcement, such as glass fiber-reinforced polymer (GFRP) bars, is used.

From Accra to Tokyo: African Sportswomen's Excellence and Respectability in Twentieth‐Century Global Sports

History, EarlyView.
Abstract This article analyses the racialized and gendered constraints faced by African sportswomen in international sporting competitions, from the interwar period to the 1980s, with a focus on the policing and expectations framing young international athletes’ acceptable behaviour.
