Males of two species of moths (Grapholitha molesta (Busck) and Hehothis virescens (F )) were flown in a sustained-flight tunnel in horizontal pheromone plumes The up-tunnel velocity of the moths increased with increasing height of flight and for G molesta was independent of tunnel wind velocities Use of moving ground patterns verified that the height of flight above the ground was the factor re...

This article examines how the relationship between sagittal and coronal anatomy, anterior cruciate ligament (ACL) graft dimensions, and tibial and femoral tunnel placement affects the posterior cruciate ligament (PCL) and roof impingement, and their undesirable clinical consequences of motion loss and instability. Based on these interrelationships, a variety of checkpoints are defined that can ...

Tarsal tunnel intracompartment pressures were determined in 10 fresh-frozen normal human adult cadaver specimens. With the foot and ankle held in mild plantarflexion and neutral eversion-inversion, mean tarsal tunnel pressure was minimal (2 +/- 1 mmHg). However, when the foot and ankle were positioned in full eversion, mean tarsal tunnel pressure increased to 32 +/- 5 mmHg (P < or = 0.005); in ...

this paper addresses the problem of quantifying the mechanical contribution of rockbolts installed systematically around tunnels (regularly spaced around the tunnel) excavated in rock masses. assuming that the mechanical contribution of grouted rockbolts is that of increasing internal pressure within a broken rock mass, a new procedure for computation of ground response curves for a circular tu...

[Purpose] The aim of the study was to investigate the ability of Semmes-Weinstein Monofilament testing to detect carpal tunnel syndrome, as well as moderate-to-severe carpal tunnel syndrome using varying thresholds and methods. [Subjects] Clinical and electrophysiological data of 62 patients (124 hands) with a mean age of 49.09±10.5 years were evaluated in this study. [Methods] Sensitivity and ...

This paper aims to estimate the distribution and magnitude of the excavation damaged zone (EDZ) caused by the tunnel boring machine (TBM) through dynamic three-dimensional large deformation finite element analysis. Coupled EulerianLagrangian (CEL) analysis was used to consider the large deformation behavior during TBM excavation. The analysis model was verified based on estimations reported in ...

In general, people who perform repetitive motions are often vulnerable to repetitive strain injuries. Because musicians must execute the same motion over and over again while practicing and performing their music, they are an example of a group that often develops these repetitive strain injuries. More specifically, musicians are known for developing neuropathies in their upper limbs, with carp...

A usability study evaluating dynamic tunnel concepts has been completed under the Aviation Safety and Security Program, Synthetic Vision Systems Project. The usability study was conducted in the Visual Imaging Simulator for Transport Aircraft Systems (VISTAS) III simulator in the form of questionnaires and pilot-in-the-loop simulation sessions. Twelve commercial pilots participated in the study...

Background: The pathophysiology of carpal tunnel syndrome is associated with increased intracarpal canal pressure. Recently, palmaris longus has been introduced as an independent risk factor for the development of carpal tunnel syndrome. The purpose of this study was to assess the association of carpal tunnel syndrome with the presence of palmaris longus tendon and functional superficial flexor...
