Creep Behaviour of Fly Ash-Based Geopolymer Concrete

Civil Engineering Dimension, 2010
Fly ash-based geopolymer concrete is manufactured using fly ash as its source material and does not use Portland cement at all. Beside fly ash, alkaline solution is also utilized to make geopolymer paste which binds the aggregates to form geopolymer ...

The gut microbiome and drug‐resistant epilepsy: Microbiome–antiseizure medication interactions and implications for pharmacoresistance

Epilepsia Open, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects approximately one‐third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a ...

Deliberate Practice Supervision to Enhance the Effectiveness of Behavioral Activation for Depression: A Case Study

Journal of Clinical Psychology, Volume 81, Issue 6, Page 526-537, June 2025.
ABSTRACT Deliberate Practice (DP) is a model of behavioral skill acquisition structured by several key tasks. The past decade has shown a consistent growth in interest in this form of learning for psychotherapy skills, with promising research suggesting DP training is superior to traditional learning methods of psychotherapy. This paper presents a case

Cognitive and affective empathy predict young children's involvement in bullying one year later

JCPP Advances, EarlyView.
The study is a secondary data analysis of the UK Stand Together trial, investigating whether affective empathy and cognitive empathy at baseline predict involvement in bullying 1 year later. Using causal inference methods on data from over 4000 primary school children, we found that high empathy was associated with a decreased risk of becoming a bully ...
