Is airway diameter measured accurately on routine axial CT scans? Comparison with true axial diameter using MPR in children with airway compression owing to pulmonary TB

open access: yesSouth African Journal of Radiology, 2010
Airway compression is a common complication of TB lymphadenopathy in children, and the diagnostic workup of patients with suspected tracheal or bronchial stenoses includes bronchoscopy and CT (computed tomography).2 This process affords the opportunity ...

Properties of Axial Diameters of a Simplex [PDF]

open access: yesDiscrete & Computational Geometry, 2011
Let S be a nondegenerate simplex in ℝn . It is proved that the minimal possible σ>0, such that a homothetic copy of S of ratio σ contains [0,1]n , is equal to $\sum_{i=1}^{n} 1/d_{i}(S)$. Here d i (S) denotes the length of a longest segment in S parallel to the ith coordinate axis.

Influence of Diameter Increase Speed on Diameter-Axial Rolling of Large 40Cr13 Stainless Steel Ring

open access: yesJournal of Physics: Conference Series, 2023
Abstract Rolling speed ratios during the rolling process are critical to ring forming in this pepper. The selected roll feed mode is constant with the increasing speed of ring diameter during the main rolling stage. Based on Deform-3D finite element software, a large size ring with a diameter of φ1530 mm was taken as the research object.

Properties of axial diameters [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1989
Λ is a lattice and K a bounded, open, convex set in En. An axial diameter of K is the maximal length Xi, of chords of K parallel to the ith lattice basis vector (1 ≤ i ≤ n). A number of properties of the axial diameters are developed. For sets K containing just one lattice point, an inequality is established; when Λ is the integral lattice, this ...

STRAIN GAUGE ANALYSIS OF AXIAL AND OFF AXIAL LOADING ON IMPLANTS FOR REPLACING FIRST MANDIBULAR MOLAR (INVITRO STUDY) [PDF]

open access: yesAlexandria Dental Journal, 2019
INTRODUCTION: Mechanical overload is thought to be one of the major causes of implant complications. It may induce loosening and fracture of the superstructure and/or implant components. Bone loss may also occur at the implant-bone interface.

Diameter-dependent axial prestretch of porcine coronary arteries and veins

open access: yesJournal of Applied Physiology, 2012
The pressure-diameter relation (PDR) and the wall strain of coronary blood vessels have important implications for coronary blood flow and arthrosclerosis, respectively. Previous studies have shown that these mechanical quantities are significantly affected by the axial stretch of the vessels.
