Elastic Water Column Modelling of an Undulating Pipeline Profile with Entrapped Air
Emptying pressurised pipelines with undulating profiles can generate subatmospheric pressure conditions that compromise structural integrity, particularly when no air admission valve is considered. One-dimensional models for this transient event have so far relied on the Rigid Wa...

Surgical management of cecal volvulus: a case report
A volvulus occurs when a loop of the intestine twists around itself and the supporting mesentery, accounting for 1–1.5% of all intestinal obstruction cases. Approximately one quarter of the colonic volvuli are cecal, with women being up to 80% of the cases. Surgical intervention,...

The Diencephalon/Falx Ratio: A Novel Mid‐Sagittal Marker for First‐Trimester Neurosonography
ABSTRACT Objectives To establish normative reference ranges for diencephalon diameter, falx cerebri length, and the diencephalon/falx (D/F) ratio between 11 + 6 and 13 + 6 weeks of gestation and to evaluate their relationship with crown–rump length (CRL). Methods This prospective...
