PURPOSE Proper femoral tunnel position is important for anatomical reconstruction of the anterior cruciate ligament (ACL). The purpose of this study was to evaluate the positions of femoral and tibial tunnels created using an accessory anteromedial portal technique in single bundle ACL reconstruction. MATERIALS AND METHODS The femoral tunnel was targeted at the mid-portion of the ACL bundles....

there are different methods to reduce drag in high speed hulls. one of these methods is a change in the shape of the body by adding longitudinal side tunnels. in this paper it has been attempted to determine the influence of the tunnel height on hydrodynamic characteristics of the hull to achieving an optimum shape for the tunnel. to achieve this purpose, numerical simulation of the problem has...

cucumbers grown under open air conditions, encounters chilling damages, during cold seasons. plastic tunnels provide suitable heat environment for growing cucumber. the objective of this research was to evaluate cucumber phonological stages and leaf area expansion within three different plastic tunnel microclimates to moderate air temperature and air humidity. three microclimates including 1. c...

background :carpal tunnel syndrome is the most prevalent compression neuropathy of upper extremity which, two of the most important risk factors of that are the female sex and manual works. in the model of international classification of function, disability and health, disease is an impairment, results in functional limitation. the goal of this study is to compare hand function of participants...

BACKGROUND It is common to place the posterior cruciate ligament (PCL) tibial tunnel with a transtibial technique using a guide that attempts to place the center of the tunnel 1 to 1.5 cm distal to the tibiofemoral joint. It is unknown how well this technique will re-create the native tibial footprint of the PCL. PURPOSE To evaluate the accuracy of tibial tunnel placement using a transtibial ...

author reports a case of 67- years- old men referred to donga university hospital silicosis who had worked in tunnel drilling where presumably had been exposed to high concentration free silica for almost 20 yr. this report is considered the first in korea to the best of our knowledge since no cases on silicosis could be reported in this occupation in reviewing various literature sources in kor...

myotomy during peroral endoscopic myotomy Peroral endoscopic myotomy (POEM) is being increasingly performed for the management of achalasia. One of the major technical challenges in performing POEM is assessing the extent of the submucosal tunnel, as this will determine the extent of the myotomy. The myotomy should extend 2–3cm beyond the lower esophageal sphincter, as an adequate cardiomyotomy...

Background: The objectives of this study were to establish a swimming capability model for largemouth bass using the FishXing (version 3) program, and to determine the swimming speed and feasibility of fish passage through a waterway tunnel. This modeling aimed to replicate the waterway tunnel connecting the Andong and Imha Reservoirs in South Korea, where there is a concern that largemouth bas...

CFD simulation is used to predict 3D flow inside different configurations. Tunnel ventilation system is one example of CFD application field. Ventilation system is important in all kind of tunnels, road tunnel, rail tunnel or waterway tunnel. In all case CFD is able to predict chronic pollutant dispersion or accidental consequences. This paper presents the model of a waterway tunnel in France i...

The theory of tunnel number 1 knots detailed in [4] provides a non-negative integer invariant depth(τ ) for a knot tunnel τ . We give various results related to the depth invariant. Noting that it equals the minimal number of Goda-Scharlemann-Thompson “tunnel moves” [6] needed to construct the tunnel, we calculate the number of distinct minimal sequences of tunnel moves that can produce a given...
