geophysical techniques remain the only ways to remotely and non-destructively sense the earth’s near subsurface and as such have the most promising prospect for rapid and accurate detection of underground tunnels. today, electrical resistivity and seismic refraction geophysical methods have been greatly developed to identify structures and underground cavities. in this study, the ability of the...

in this paper the separation of saffron stigma from stamen and petal in a vertical wind tunnel has been evaluated. a wind tunnel with adjustable speed of 0.1 m s-1 intervals has been developed and used for the experiments. floating velocities of flower components (petal, stigma and stamen) were measured at one, eight, 38 and 60 hours after harvesting. subsequently, the separation was tested by ...

  Abstract   Background: The pathophysiology of carpal tunnel syndrome is associated with   increased intracarpal canal pressure. Recently, palmaris longus has been introduced   as an independent risk factor for the development of carpal tunnel syndrome. The   purpose of this study was to assess the association of carpal tunnel syndrome with   the presence of palmaris longus tendon and function...

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...

This paper presents a novel Neural Network application in order to estimate Air Pollutant Levels. The application considers both Pollutant concentrations and Meteorological variables. In order to compute the Air Pollutant Level the method considers three important stages. In first stage, A process to validate data information and built a threedimensional Information Feature Vector with Pollutan...

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...

The Stuttgart S-Bahn network comprises six subway lines and is used by approximately 425,000 people on a daily basis. In previous studies in other cities, it was found that subways can be source collection point of particulate matter (PM), which detrimental to human health. This study focused making an initial assessment the pollution situation inside trains underground platforms. Real-time mea...

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.
