Microstructure and Martensitic Transformation Behaviors of Explosively Welded NiTi/NiTi Laminates

Chinese Journal of Aeronautics, 2007
AbstractThe study is a first attempt to prepare bulk NiTi/NiTi shape memory alloy (SMA) laminates with a macroscopic heterogeneous composition by explosive welding and investigate their microstructures and martensitic transformation behaviors. After explosive welding, a perfect interfacial bonding between the two components and a reversible martensitic

Outcomes of Root Canal Treatment in Patients With Autoimmune Disease: A Retrospective Case–Control Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim The purpose of this study was to compare the outcome of nonsurgical root canal treatment (RCT) in patients with autoimmune diseases (AD) with the outcome in patients without AD. The null hypothesis was: there is no difference in the outcomes of RCT regardless of the patient group. Results were also compared among AD subgroups: inflammatory
