INTRODUCTION: Clinical studies of carpal tunnel syndrome (CTS), a pressure-induced neuropathy of the median nerve, are limited by the difficulty of evaluating the early stages of pathology. Thus, a validated animal model of CTS is an important need. A proper animal model would have comparable anatomy to the human carpal tunnel. In addition, because carpal tunnel syndrome is characterized by inc...

The study of palaeo-glacial landforms and sediments can give insights into the nature dynamics ice sheets. This is particularly case with regards to subglacial record, which challenging observe in contemporary glaciated settings hence remains only partially understood. hydrological system an essential component dynamics, where increased water pressure enhances motion sediment deformation, thus ...

Because of the inherent inefficiency of jet propulsion, squid are considered to be at a competitive disadvantage compared with fishes, which generally depend on forms of undulatory/oscillatory locomotion. Some squid, such as the brief squid Lolliguncula brevis, swim at low speeds in shallow-water complex environments, relying heavily on fin activity. Consequently, their swimming costs may be lo...

BACKGROUND An anatomic reconstruction of coracoclavicular (CC) ligaments typically requires drilling tunnels in the clavicle. An increase in fracture complications has been associated with graft tunnel position. A method of drilling clavicle tunnels that would better re-create anatomic function of the CC ligaments without increasing fracture risk would be an improvement. PURPOSE To evaluate t...

According to construction scheme of some weak surrounding rock large span double and multi-arch tunnel works, finite element value simulation method is adopted to research weak surrounding rock deformation characteristic, anchor bolt mechanics characteristic, preliminary support and secondary lining structure mechanical characteristics, etc, and the research result shows that: repeatedly distur...

In order to solve the problem that hole-forming rate of boreholes is low and it difficult reach designed length when supporting a long pipe shed in loose stratum shallow buried section long-span tunnel, necessary pre-reinforce improve strength integrity surrounding rock. Relying on grouting project at exit Botanggou assumed material Newtonian fluid steel floral tube shows cylindrical infiltrati...

It is proposed that the adverse effects from secondary diaphragmrupture in an expansion tunnelmaybe reducedor eliminated by orienting the tunnel vertically, matching the test gas pressure and the accelerator gas pressure, and initially separating the test gas from the accelerator gas by density stratification. This proposed configuration is termed the vertical expansion tunnel. Two benefits are...
