Axial Pile Capacity of Large Diameter Cylinder Piles
From Research to Practice in Geotechnical Engineering, 2008This 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.

Axial dispersion effects with small diameter adsorbent particles
Adsorption, 2018Macropore 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 ...

Measurement of the Aortic Diameter in Plain Axial Cardiac Cine MRI
2015We address the task of aortic diameter measurement in (noncontrast- enhanced) plain axial cardiac cine MRI. To this end, we set up a likelihood maximization problem which allows us to recover globally optimal aorta locations and diameters of the cine sequence efficiently.

Chemie Ingenieur Technik, 2015
AbstractExperiments are conducted in a bubble column reactor with inner diameter of 970 mm at atmospheric pressure with an air/water system at height‐to‐diameter ratios of 1 and below. Axial and radial dispersion coefficients are measured using a tracer, which is detected by conductivity probes. An analytical mathematical model for the determination of

Distribution of 15- and 137-?? Diameter Microspheres in the Dog Lung in the Axial Plane
Investigative Radiology, 1986Oleic acid infusion, as a model of fat embolism, produces a predominantly peripheral lesion in the dog lung. The lung injury corresponds to the peripheral distribution of labeled oleic acid. The basis for this distribution of oleic acid is not known.

Corneal diameter and axial length in congenital glaucoma.
Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 1985The corneal diameter was recorded and the ocular axial length measured by A-scan ultrasonography in 31 eyes of 17 children (ages 0.05 to 7.0 years) who had undergone or were about to undergo surgery for primary congenital glaucoma. These measurements were also done in 60 normal eyes of 33 children (ages 0.20 to 9.6 years) undergoing nonophthalmic ...

Axial laser heating of small-diameter theta-pinch plasmas
Applied Physics Letters, 1978Small 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.

Measuring the long diameter of the esophageal hiatus using axial CT images
European Journal of RadiologyThe absence of normative anatomical benchmarks often leads to suboptimal crural closure during anti-reflux surgery. The hiatal long diameter represents a favorable anatomical parameter for measurement. This study therefore aimed to: 1) Validate a straightforward method for measuring it using axial CT images; 2) Establish normative thresholds for this ...

Development of the Axial Splitting Process for Small Diameter Brass Tubes
Materials Science Forum, 2016We developed the equipment for splitting the long and small diameter tube, with using a splitting tool which was previously developed [1]. The splitting target is brass tube. Its length is about 500mm and the diameter is about 19mm. Because of the high aspect ratio, it is considered to cause a buckling easily.

Axial rupture of large-diameter, gas-pressurised, steel pipes
International Journal of Pressure Vessels and Piping, 1985Abstract As part of an experimental programme to characterise the internal and external fluid dynamic forces generated by failure of high-pressure pipework, the development of an axial breach in large gas-pressurised steel pipes has been studied.
