Excavation of shallow tunnels such as subways in urban areas plays a significant role as a life line and investigation of the soil behavior against tunnel construction is one of the vital subjects studied in the geotechnical scope. Nowadays, urban tunnels are mostly drilled by T.B.Ms and changing the applied forces to tunnel lining is one of the most risky matters while drilling tunnels by thes...

In this research, we analyzed the multi-functional role of a tunnel barrier that can be integrated in devices. This tunnel barrier, acting as an internal resistor, changes its resistance with applied bias. Therefore, the current flow in the devices can be controlled by a tunneling mechanism that modifies the tunnel barrier thickness for non-linearity and switching uniformity of devices. When a ...

NSIS Quality of Service (QoS) signaling enables applications to perform QoS reservation along a data flow path. When the data flow path contains IP tunnel segments, NSIS QoS signaling has no effect within those tunnel segments. Therefore, the resulting tunnel segments could become the weakest QoS link and invalidate the QoS efforts in the rest of the end-to-end path. The problem with NSIS signa...

Purpose. The palmaris longus profundus has been documented throughout the literature as a cause of carpal tunnel syndrome. We present a case of palmaris profundus tendon removal during the revision of carpal tunnel release. Method. During a carpal tunnel release in a 66-year-old woman, palmaris profundus tendon was found inside the tunnel under the transverse carpal ligament, just above the med...

Syntheses and magnetic structural characterization of hexa-iron complexes derivatized salicylaldoximes are discussed. Complexation Fe(BF4)2·6H2O with each ligand (H2L1 H4L2) in a methanolic-pyridine solution resulted compounds (C1 C2, respectively), which contain two near-parallel metal triangles [Fe3–μ3-O], linked by six fluoride bridges stabilized hydrogen-bonded proton between the μ3-O group...

PURPOSE The purpose of this study was to assess the differences in bone tunnel apertures between the trans-accessory medial portal (trans-AMP) technique and the transtibial (TT) technique in double-bundle anterior cruciate ligament reconstruction. The extent of ovalization and the frequency of overlap of the two tunnel apertures were compared. METHODS The simulation of femoral tunnel drilling...

OBJECTIVE Extracardiac pericardial-flap lateral tunnel Fontan operation has the theoretical advantage of growth potentiality of the extracardiac tunnels. The mid-term results of this technique and morphologic change of the lateral tunnel were studied. METHODS Clinical data were reviewed in 42 patients who underwent extracardiac pericardial-flap lateral tunnel Fontan operation between November...

OBJECTIVE To describe the prevalence of carpal tunnel syndrome in a sample of 200 healthy hospital workers, establishing the respective epidemiological associations. MATERIALS AND METHODS Two hundred individuals were submitted to wrist ultrasonography to measure the median nerve area. They were questioned and examined for epidemiological data, body mass index, carpal tunnel syndrome signs and...
