Behaviour of Small Diameter Steel Tubes Under Axial Compression

open access: yesStructures, 2017
Abstract Small diameter steel tubes are used in many civil engineering applications. Recently, the behaviour of concrete columns reinforced with small diameter steel tubes was experimentally and analytically investigated. This study explores the effect of unsupported length to the outside diameter ( L / D ) ratio on the axial compressive behaviour of ...

Axial pulmonary trunk diameter variations during the cardiac cycle

Surgical and Radiologic Anatomy, 2020
Previous studies have shown a correlation between axial pulmonary trunk diameter (PTD) on chest computed tomography (CT) and pulmonary artery pressure. However, it is not known whether the PTD slices measured on chest CT have been recorded during the systolic or diastolic phase.

Axial Diameter is Superior to Volumetric Measurement in Predicting Ureteral Stone Passage

Urology Practice, 2021
We sought to investigate the clinical utility of volumetric measurements in predicting passage of symptomatic ureteral calculi.We performed a retrospective review of patients seen in the emergency department for computerized tomography-confirmed symptomatic ureteral calculi with a subsequent discharge for trial of passage.

Pancreatic cyst characterization: maximum axial diameter does not measure up

HPB, 2021
Unidimensional size is commonly used to risk stratify pancreatic cysts (PCs) despite inconsistent performance. The current study aimed to determine if unidimensional size, demonstrated by maximum axial diameter (MAD), is an appropriate surrogate measurement for volume and surface area.Patients with cross-sectional imaging of PCs from 2012 to 2013 were ...

Association between axial length and horizontal and vertical globe diameters

Graefe's Archive for Clinical and Experimental Ophthalmology, 2016
To assess relationships between axial length and the horizontal and vertical globe diameters.The study consisted of enucleated human eyes. The horizontal, vertical, and sagittal diameters were measured.The study included 135 globes removed because of malignant uveal melanoma (111 globes) or end-stage painful glaucoma (n = 24 eyes).

Corneal Diameter, Axial Length, and Intraocular Pressure in Premature Infants

Ophthalmology, 1992
Seventy premature infants 25 to 37 weeks' postconceptional age were examined during their first week of life to determine the correlation of corneal diameter, axial length, and intraocular pressure with gestational age and birth weight.Corneal diameter measurement was determined with corneal templates, total axial length with standardized A-scan ...
