Simulated Self‐Assessment and Error Correction in Preclinical Prosthodontics: Insights From 3D‐Printed Models

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Developing self‐assessment and defect correction skills is essential for dental students to ensure high‐quality clinical practice. However, these skills are often insufficiently addressed in dental education. This study evaluates students' ability to assess and correct crown preparation defects through a structured exercise ...

Improved Suter Transform for Pump-Turbine Characteristics

International Journal of Fluid Machinery and Systems, 2010
Standard dimensionless parameters cannot simultaneously represent all operation modes of a pump-turbine. They either have singularities at E=0 and multiple values in the ‘unstable’ areas, or else get singular at n=0. P. Suter (1966) introduced an alternative set of variables which avoids singularity and always remains unique-valued.

Flow‐controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery

Equine Veterinary Journal, EarlyView.
Abstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...
