Assessment of Accidental Torsion in Building Structures Using Static and Dynamic Analysis Procedures
Background: Left ventricular torsion is one of the most important biomechanical parameters of heart that routinely is measured in short axis view. A review of the literature has indicated that assessment of left ventricular torsion in short axis view has some limitations. In the present study, we evaluated whether torsion angle assessment in long axis view can be used as a diagnostic biomechan...
During the 6-m period, 24 patients with acute scrotal pain were referred to the Nuclear Medicine Department of Shaheed Labbafi-Nejad hospital. Their age ranged from 9 to 84 (mean 28.8) years. Twelve scans were selected for the study. The scans were performed on angiographic and static phases, using Tc-pertechnetate. Of the above mentioned cases, one had acute testicular torsion (pre and p...
The spine is routinely subjected to repetitive complex loading consisting of axial compression, torsion, flexion and extension. Mechanical loading is one of the important causes of spinal diseases, including disc herniation and disc degeneration. It is known that static and dynamic compression can lead to progressive disc degeneration, but little is known about the mechanobiology of the disc su...
In this paper, we analyze trajectories of spacelike curves that are critical points a Lagrangian depending on its total torsion. We focus two important families spacetimes, generalized Robertson–Walker and standard static spacetimes. For the former, show such those with constant curvature. latter, also obtain characterization in terms curvature trajectory but case measured an appropriate confor...
The “measurability” of the non-minimal coupling is discussed by considering the correction to the Newtonian static potential in the semi-classical approach. The coefficient of the “gravitational Darwin term” (GDT) gets redefined by the non-minimal torsion scalar couplings. Based on a similar analysis of the GDT in the effective field theory approach to non-minimal scalar we conclude that for re...
