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 ...

Impact of Pupil Diameter on Axial Growth in Orthokeratology

Optometry and Vision Science, 2012
To compare axial elongation between myopic orthokeratology (OK) contact lens and spectacle wearers, and to investigate the impact of pupil diameter on axial growth in myopic children after OK treatment.Fifty-two Chinese children aged 9 to 14 years were enrolled in this study, 27 for the OK group and 25 for the single vision spectacle lenses (SVL) group.

Axial dispersion effects with small diameter adsorbent particles

Adsorption, 2018
Macropore diffusion is traditionally assumed to control the mass transfer rate in columns packed with zeolite particles in an oxygen production process. While numerous studies have confirmed this assumption for the particle size used in industrial size pressure swing adsorption (PSA) processes, it has not been validated for the much smaller particle ...

Axial Pile Capacity of Large Diameter Cylinder Piles

From Research to Practice in Geotechnical Engineering, 2008
This paper reports on the behavior of large diameter cylinder piles under both driving and static conditions. Of special interest is the understanding of the tip resistance and the associated soil column within the pile under static and dynamic conditions.

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).

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.

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 ...

Axial laser heating of small-diameter theta-pinch plasmas

Applied Physics Letters, 1978
Small 5-mm-diam high-density 3×1017 cm−3 ϑ-pinch plasma columns 1-m long have been heated by intense long-wavelength laser radiation (10 μ) along their entire length. Refractive beam trapping has been achieved when laser heating begins during or before the ϑ-pinch implosion.

Flow through tubes with sinusoidal axial variations in diameter

AIChE Journal, 1979
AbstractAn iteration technique has been developed to solve the equations of motion for flow of an incompressible Newtonian fluid through a circular tube with a radius which varies sinusoidally in the axial direction. The iteration is essentially geometric; one proceeds from a solution for flow through a tube in which the wavelength of diameter change ...

Design and Fabrication of 25mm Diameter Axial Gradient Singlets

Gradient Index Optical Systems, 1994
Several F/3 single element axial gradient index lenses with a focal length of 75 mm have been fabricated and tested with emphasis being on performance and repeatability. The lens material was made via a fusion/diffusion process. This paper discusses the results of this endeavor.
