Revision anterior cruciate ligament reconstruction has inherent technical challenges not encountered during primary reconstruction. Prior tunnel placement and tunnel lysis can significantly alter graft fixation, compromising patient outcome. Preoperative recognition of patients with existing tunnel overlap and severe tunnel lysis will allow appropriate surgical planning and patient counseling, ...

In the process of the highway tunnel construction, the stability and the reliability of tunnel rock is an important guarantee to ensure safety construction. Tunnel surrounding rock deformation monitoring is an important method for obtaining information on surrounding rock and controlling tunnel stability in the period of construction. Forecasting deformation of surrounding rock is the key to es...

In [6], Goda, Scharlemann, and Thompson described a general construction of all tunnels of tunnel number 1 knots using “tunnel moves”. The theory of tunnels introduced in [3] provides a combinatorial approach to understanding tunnel moves. We use it to calculate the number of distinct minimal sequences of such moves that can produce a given tunnel. As a consequence, we see that for a sparse inf...

high speed wind tunnels are widely used in the study of fluid flow behavior around various objects. the air flow in the starting step of supersonic wind tunnels is transient including strong shock waves caused by the interaction of the tunnel main stream and the boundary layer at walls. to arrive in running step, the tunnel must be designed so as these waves leave immediately the test section. ...

PURPOSE Extensive tunnel expansion in hamstring anterior cruciate ligament (ACL) reconstruction can complicate revision surgery. The purpose of this study was to examine our hypothesis that compaction of a bone dowel into the tibial tunnel reduces the cross-sectional area of the tunnel on the day of surgery and limits tunnel expansion to that of the cross-sectional area of the reamer at 4 month...

With the complex of the tunnel construction, tunnel construction become more and more difficult, in order to ensure the safety of tunnel construction, the paper introduced a kind of tunnel construction monitoring system based on sensor. The system achieves the real-time monitoring of tunnel construction environment including temperature and humidity, gas concentration, dust concentration, locat...

Tophaceous gout is a recognized cause of carpal tunnel syndrome. Of 2649 carpal tunnel releases, 15 hands in 13 patients were identified with tophaceous gout in the carpal tunnel. The incidence of tophaceous gout in the carpal tunnel was 0.6%. Twelve of 13 patients were male, and 8 of 10 patients with a history of gout developed carpal tunnel syndrome despite adequate medical treatment. Thus, c...

Carpal tunnel syndrome is diagnosed by clinical symptoms, Tinel's sign, Phalen's test and electromyography. Carpal tunnel pressure measurement can also aid in the precise identification of excessive pressure sites that indicate locations for release. In this study, pressure measurements made during endoscopic carpal tunnel release at 5 points were significantly higher anywhere in the carpal tun...

A FOUNDATION FOR TUNNEL-COMPLEX PROTOCOLS Alwyn E. Goodloe Carl A. Gunter Tunnel-complex protocols construct different tunnel topologies by directing tunnelestablishment protocols to set up pair-wise tunnels between different nodes, where the resulting tunnel complex satisfies some security requirement such as negotiating a defense in depth. Such protocols ease the burden on network managers de...
