J-R curve determination of G20Mn5QT cast steel using CT specimen with varying in-plane and out-of-plane constraints based on normalization method and GTN model

Journal of Materials Research and Technology, 2022
In this paper, the fracture toughness tests of compact tensile (CT) specimens with varying in-plane constraints were carried out. J-R curves of G20Mn5QT cast steel were firstly measured by normalization method.

Multiple pregnancy with complete hydatidiform mole and coexisting normal fetus: systematic review and meta-analysis of clinical outcomes from non-randomized studies. [PDF]

Ultrasound Obstet Gynecol
ABSTRACT Objective Complete hydatidiform mole and coexisting normal fetus (CHMCF) is a rare condition for which there is significant heterogeneity in diagnosis, counseling and management of complications. The objective of this study was to summarize the prevalence of clinical outcomes in reported cases of CHMCF.
