surface-piercing propellers (spps) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. unlike the submerged propellers, theoretical methods have no significant application on simulation of sppsbecause of problems related to modeling of these propeller...

The carpal tunnel in the wrist is formed by the interconnected carpal bones and the transverse carpal ligament (TCL). The tunnel contents include the median nerve, which is susceptible to entrapment in the space-limited tunnel leading to carpal tunnel syndrome (CTS). CTS patients have increased flattening of the median nerve which is alleviated after surgically transecting the TCL to increase c...

Building information modelling (BIM) can be applied to tunnel engineering to address a number of problems, including complex structure, extensive design, long construction cycle and increased security risks. To promote the development of tunnel engineering in China, this paper combines actual cases, including the Xingu mountain tunnel and the Shigu Mountain tunnel, to systematically analyse BIM...

BACKGROUND Over 60% of patients with carpal tunnel syndrome present with symptoms and findings of nerve compression in both hands. Our goal was to compare patient-rated difficulties in performing activities of daily living in the early postoperative period between those undergoing bilateral carpal tunnel release and those undergoing unilateral carpal tunnel release. METHODS This prospective c...

An accurate theoretical model to predict the extent and mechanical behavior of excavation damage zone (EDZ) in surrounding rock deep-buried tunnel is great importance for practical engineering applications. Using elastic-plastic theory combined with analysis on stress characteristics rock, this paper present a EDZ formation evolution. A three-zone composite was established surround correspondin...

This paper suggests a new set of analytical solutions for predicting leakage-induced seepage field and ground settlement in saturated clay. A unique feature of the solutions presented is considering the effect of the tunnel lining through the relative permeability between the tunnel and the soil. Through the superposition method, the proposed method can be easily extended to twin parallel tunne...

  Anatomical vascular variations are rare causes of carpal tunnel syndrome. An aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. This article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radi...
