Differential conductance spectroscopy performed in the high bias regime---in which applied voltage exceeds sample work function---is a suboptimal measure of local density states due to effects changing tunnel barrier. Additionally, large oftentimes makes constant-height measurement experimentally impractical, lending constant-current an advantageous edge; but differential that case is even furt...

  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...

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...

In order to take advantage of heat released during composting, the autothermal drying process requires the maintenance of adequate air flow combined with temperature. The aim of this paper was to construct a drying tunnel enabling the automatic control and regulation of the basic process parameters for biomass drying (organic fraction of municipal solid waste together with plant structural mate...

Future linear accelerators require new survey techniques to achieve the necessary alignment precision. For TESLA, the demanded accuracy for the alignment of the components is 0.5mm horizontal and 0.2mm vertical, both on each 600m section. Other proposed linear colliders require similar accuracies. These demands can not be fulfilled with common, open-air geodetic methods, mainly because of refra...

In the North Sea, an array of wind profiling wind lidars were deployed mainly on offshore platforms. The purpose was to observe free stream winds at hub height. Eight lidars were validated prior to offshore deployment with observations from cup anemometers at 60, 80, 100 and 116 m on an onshore met mast situated in flat terrain. The so-called “NORSEWInD standard” for comparing lidar and mast wi...

each year, millions of liters of toxic liquid, are used to combat with pests and plant diseases in farms. the wide spread use of chemical pesticides causes great environmental hazards. particles drift is one of the main problems in spraying which results in the contamination of farm lands, humans and animals. management of particle size is regarded as the main factor in drift control. in this s...
