Abstract Aim Suspected biliary pathology necessitates imaging to assess for gallstones. Ultrasound is gold-standard but often limited by bowel gas/body habitus. MRCP has become popular due superior ability detect CBD stones. CT used with concerns of a wider differential diagnosis. This study aimed explore the diagnostic journey suspected gallstone patients, and whether increased furthered patie...

The abstraction of the active hydrogen of RCOCH2R by a base catalyst B M , and the subsequent formation of the enolate [RCOCHR ] M are described in Eq. 1 (deprotonation process). Secondly, the creation of a C–N bond, in which [RCOCHR ] M reacts with R ONO to form complex [RCOCHNO(OR )R ] M , is shown in Eq. 2 (C–N bond formation process). Finally, the reaction between [RCOCHNO(OR )R ] M with ba...

In this contribution, a series of isothermal compression tests for the 825 nickel-based alloy were performed using Gleeble-3800 computer-controlled thermomechanical simulator at temperature range 850 °C to 1150 and strain rate 0.14 s−1 2.72 s−1. The hot deformation equation is derived from piecewise model based on theory work hardening-dynamic recovery dynamic recrystallization (DRX), respectiv...
