Explainable prediction model for punching shear strength of FRP-RC slabs based on kernel density estimation and XGBoost.

Reinforced concrete (RC) slabs are widely used in modern building structures due to their superior properties and ease of construction. However, their mechanical properties are limited by their punching shear strength in the connection region with the columns. Researchers have attempted to add steel reinforcement in the form of studs and randomly distributed fibers to concrete slabs to improve the punching strength.

Effect of GFRP Stirrup Confinement on the Bond Strength of GFRP-RC Beams.

The current provisions for development length in the ACI 440.11 code disregard the confinement effect provided by stirrups on the bond strength of longitudinal bars and require splice lengths that pose implementation challenges. Given the significant improvement in GFRP material properties, this study investigated the bond strength of sand-coated GFRP bars and proposed a new factor to include the effect of stirrup confinement on the bond-strength provisions.

Development of Biodegradable and Recyclable FRLM Composites Incorporating Cork Aggregates for Sustainable Construction Practices.

Reducing energy consumption in the building sector has driven the search for more sustainable construction methods. This study explores the potential of cork-modified mortars reinforced with basalt fabric, focusing on optimizing both mechanical and hygroscopic properties. Six mortar mixtures were produced using a breathable structural mortar made from pure natural hydraulic lime, incorporating varying percentages (0-3%) of cork granules () as lightweight aggregates.

An Atypical Case of Creutzfeldt-Jakob Syndrome Presenting with Cacosmia and Amyloid Positivity.

This report presents a challenging case of Creutzfeldt-Jakob Disease (CJD), a rare and rapidly progressing neurological disorder. The patient exhibited diverse and progressive neuro-psychiatric symptoms, including memory impairment, behavioral changes, and hallucinations associated with cacosmia. The diagnosis of CJD is complicated due to its variable clinical presentation, limited awareness, and the need for tissue pathology confirmation.

Presepsin in Human Milk Is Delivery Mode and Gender Dependent.

Breast milk (BM) is a unique food due to its nutritional composition and anti-inflammatory characteristics. Evidence has emerged on the role of Presepsin (PSEP) as a reliable marker of early sepsis diagnosis. In the present study, we aimed to investigate the measurability of PSEP in BM according to different maturation stages (colostrum, C; transition, Tr; and mature milks, Mt) and corrected for delivery mode and gender.
