The 10.6 km long Sabzkuh water conveyance tunnel is currently under construction in High Zagros structural zone, located in western Iran, has used conventional (in section T1) and mechanized (in section T2) methods. The section T1 of the tunnel driven through alluvial geological units with great complexity in an area high potential for sliding and water-bearing fault which has made the excavati...

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 radial...

background: stroke is the first cause of morbidity all around the world. entrapment neuropathies are a known complication of stroke. the objective of this study is to assess the frequency of subclinical carpal tunnel syndrome in the healthy and paretic hands of stroke patients. methods: the authors performed nerve conduction study in the first three days after admission in 39 stroke patients wi...

Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

this presentation will cover, appearance of normal nerve versus tendon; anisotropy (advantage and disadvantage); special case carpal tunnel; tendinopathy; nerve impingement; special case cubital tunnel.

Tunnel Broker model, as defined in RFC3053, is a solution to the automation of IPv6 address assignment and IPv6 over IPv4 tunnel management. Tunnel server selection and fault tolerance are two big problems for a Tunnel Broker system. Anycast makes it possible to solve the tunnel server selection problem and improve the system’s fault tolerance. This paper proposes an architecture of the Tunnel ...

numerous causes are reported for ulnar nerve compression at the wrist, known as guyon's tunnel syndrome. in the present article, a patient with guyon's tunnel syndrome during pregnancy concomitant with an anomaly of ulnar nerve is described. a 29-year-old iranian woman presented with clinical features of guyon's tunnel syndrome (pain and paresthesia in the fifth finger of the left hand and atro...

AIM The aim of this study was to try to find parametric ratios for the diagnosis and pathophysiology of carpal tunnel syndrome using MR. MATERIAL AND METHODS Dominant side wrist MRI examinations of 27 female carpal tunnel patients and 21 normal females were compared. The carpal tunnel contents area / carpal tunnel cross section area ratio was defined, analysed and discussed with the literatur...

in this paper, a systematic approach is presented for optimal design of tunnel support lining using two-dimensional finite element analysis models of soil-structure interaction developed in abaqus software and the modified colliding bodies optimization (mcbo) algorithm implemented in matlab environment. this approach is then employed to study the influence of variable geometrical and geo-mechan...

conclusion the anterior tarsal tunnel syndrome is a known disease. a high index of clinical suspicion is required while dealing with the chronic cases. a detailed history to rule out any traumatic event is necessary too. timely investigations and surgical release give dramatic relief. case presentation a 40 -year-old male patient was presented with the history of persistent pain along the dorsa...
