Journal of Geotechnical Engineering, 1985
Soil arching action or “bin effect” is usually quantified by use of a horizontal differential element whose support derives in part from Rankine theory. In the 1940's, Krynine mathematically proved this incorrect. The present analysis substitutes a catenary arch describing the path of the minor principal stress, which thus is complementary to a ...

It is shown theoretically that the arch describing the minor principal stress in the soil behind a retaining wall can be approximated by a catenary which is very close to circular in the range of interest.

Coarctation and hypoplasia of the aortic arch: Will the arch grow?
The Annals of Thoracic Surgery, 1991Hypoplasia of the transverse aortic arch of various degrees of severity is commonly seen in infants who have coarctation of the aorta. It is more often present when the coarctation is associated with intracardiac lesions that diminish or limit forward flow in the ascending aorta and promote right to left flow through an arterial duct.

Double Aortic Arch with Left Arch Atresia
Heart, Lung and Circulation, 2009A girl, having an echocardiogram suggestive of double aortic arch, underwent a cardiac multidetector computed tomography (MDCT) examination. MDCT revealed double aortic arch with left arch atresia distal to the left subclavian artery. The left common carotid artery and the left subclavian artery arose from the left arch, the right common carotid artery

Total Arch Replacement for a Distal Aortic Arch Aneurysm With Right Aortic Arch
The Annals of Thoracic Surgery, 2007Right-sided aortic arch accompanied by an aberrant origin of the left subclavian artery is rare and seen in 0.05% approximately 0.1% of the population. A 73-year-old woman with this anomaly was admitted to our institution because of the enlargement of the distal aortic arch aneurysm. She also had mild dysphagia.

Arch index as a predictor of arch height
The Foot, 1997Abstract A number of indirect methods of estimating the height of the medial longitudinal arch of the foot have been devised.1 The efficacy of the arch index as a valid and convenient predictor of arch height has been questioned.2 In this study, arch index was measured in 45 elderly subjects and navicular height was measured from weight bearing ...

Development of Arch Action in Arch Dams
Journal of the Power Division, 1965Considering hydrostatic pressure as the only external load on an arch dam, the influence of the reservoir elevation and the elastic deformability of the foundations is investigated using the crown cantilever method. The arch and cantilever action are evaluated on the basis of a shear and moment criterion, representing the relative magnitude of the ...
