Resident Satisfaction With Orthodontic Training: Evaluating Experiences and Program
Journal of Dental Education, EarlyView.ABSTRACT Introduction The satisfaction of orthodontic residents with their training programs is a key indicator of program effectiveness and serves as an important guide for the improvement of educational and clinical training programs. This survey was conducted to evaluate the perceived satisfaction of orthodontic residents with the current training ...

Journal of Quaternary Science, EarlyView.ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Development of ± 550 kV DC GIS Basin Insulator
High Voltage, EarlyView.ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.
