In this paper, the author studies about the traffic safety technology of highway tunnel group. In this study measured traffic safety technology in the access zone of tunnels including tunnel luminance under diverse climate conditions were measured and luminance of the threshold zone were estimated. Then operating traffic safety technology of tunnel in China was compared and analyzed and, based ...
Much research is currently being carried out in the field of nanoelectronic circuit design [1], [2]. One of the proposed quantum devices is the Single Electron Tunneling (SET) device. This SET device consists of a tunnel junction, through which only an integer number of electrons can tunnel. A new local tunnel condition will be derived in this paper. The derivation is based on the discrete char...
In order to solve the problems of large energy consumption existing in tunnel lighting control system, an automatic control system of tunnel lighting is designed based on stepless control method. The tunnel lighting control model is established based on “Specifications for Design of Ventilation and Lighting of Highway Tunnel (China)”. Simulation of tunnel lighting control based on the establish...
UNLABELLED The purpose of this cadaver study about the ACL graft was to compare a "Lateral Tibial Tunnel" (LTT) and a "classic, anteroMedial Tibial Tunnel" (MTT), as to fixation strength and mode of failure. Ten pairs of fresh frozen human proximal tibias were used. In one of both tibias a classic anteromedial tunnel was used, versus a lateral tibial tunnel in the contralateral knee. Autologous...
We report on the successful integration of low-cost, conformal, and versatile atomic layer deposited (ALD) dielectric in Ni–Al2O3–Co magnetic tunnel junctions (MTJs) where the Ni is coated with a spin-filtering graphene membrane. The ALD tunnel barriers, as thin as 0.6 nm, are grown layer-by-layer in a simple, low-vacuum, ozone-based process, which yields high-quality electron-transport barrier...
Introduction: Postoperative periorbital edema and ecchymosis is one of the main complication of rhinoplasty. This complication is mostly due to lateral osteotomy. During performing the endonasal lateral osteotomy, with the goal of reducing injury to surrounding tissues and reducing the postoperative edema and ecchymosis. The aim of this study goal was to determine whether creating a subperioste...
Background & Aim: Many factors influence the tensile strength of the tendon in a tendon-bone tunnel complex. The purpose of this study is to determine the influence of tendon length & time of implantation of the tendon in the bone tunnel on the tensile strength of the tendon in a rabbit model. Material and Methods: In this prospective study fourteen adult(age 6 months) White New Zealand rab...
Background & Aims: Carpal tunnel surgery is mostly performed in the field of hand surgery. During the procedure the transverse carpal ligament is cut. This ligament has an important role in the strength of the hand. Objective evaluation of the hand strength can be used as a judgment of patient’s ability to return to the previous level of their hand function. The purpose of this study was to eva...
BACKGROUND The bicipital tunnel is the extra-articular, fibro-osseous structure that encloses the long head of the biceps tendon. METHODS Twelve cadaveric shoulder specimens underwent in situ casting of the bicipital tunnel with methyl methacrylate cement to demonstrate structural competence (n = 6) and en bloc harvest with gross and histologic evaluation (n = 6). The percentage of empty tunn...
BACKGROUND Anatomic footprint restoration of anterior cruciate ligament (ACL) is recommended during reconstruction surgery. The purpose of this study was to compare and analyze the femoral and tibial tunnel positions of transtibial single bundle (SB) and transportal double bundle (DB) ACL reconstruction using three-dimensional computed tomography (3D-CT). METHODS In this study, 26 patients wh...
