Inflammatory Bowel Disease in Kazakhstan: Phenotypes, Disease Activity, and Treatment Patterns from a National Registry

Background/Objectives: Inflammatory bowel diseases (IBDs) are an increasingly important global health problem, yet Central Asia remains underrepresented in international IBD data. To evaluate the clinical and demographic characteristics of patients included in the national multic...

Bottom-Hole Pressure Optimization in Marine-Continental Transitional Shale Gas Reservoir Considering Stress Sensitivity

Abstract The bottom-hole pressure (BHP) directly affects the stress state in formation, which in turn affects the productivity of hydraulically fractured horizontal wells. In this study, the porosity and permeability stress sensitivity experiments were conducted on different mari...

Structural Evolution of RAFT-Modified Unsaturated Polyester Copolymers: Effects of CPDT Concentration, Acidic Comonomer Structure, and Polyester Matrix Architecture

Unsaturated polyester resins (UPRs) represent challenging systems for reversible-deactivation radical polymerization (RDRP) because chain propagation, branching, and localized gelation may occur concurrently. This study systematically investigates the influence of the concentrati...
