BACKGROUND Endoscopic carpal tunnel release (ECTR) has gained recognition as an alternative to the current gold standard, the open carpal tunnel release (OCTR). Detailed technical points for the ECTR have not been explained in the literature, especially for surgeons who are considering trying this technique. OBJECTIVES In this paper, we present our 5-year experience with the ECTR and special ...

Analysis of advanced displacement in construction progress of tunnel excavation with weak surrounding rock is carried out by numerical method and comparison of model test result. In allusion to the problems of regional landslides and extruded large-deformation seriously impacting the stability of rock mass in construction process of large-section tunnel with weak surrounding rock, the elastic-p...

This study aims to improve safety and security for vehicle users passing through the tunnel, identify construction of underpasses at railroad crossings, minimize queue lengths delays while crossing on Jalan Sultan Hasanudin, Pasar Tambun, Bekasi road smoothness, provide recommendations need pedestrian facilities Hasanudin section. There is a potential risk pedestrians, because there are no faci...

With the development of Transportation Highway and railroad build, mining tunnel geological exploration in the road construction in the proportion of great. This paper presents a design of image processing software of Geological Engineering images for automatic analysis and processing. At present, the technology of image processing, most algorithms are based on the specific image information of...

The number of railroad events reported to the Agency for Toxic Substances and Disease Registry's Hazardous Substances Emergency Events Surveillance system increased from 84 in 1993 to 177 in 1998. Comparisons of data on railroad and non-railroad events were made. The results overall indicated a greater potential impact of railroad events on public health. A median number of 2039 persons were li...

Several engineering practices have shown that the excavation of shallow-buried tunnels beneath major roads, as well selection appropriate measures and construction methods, has a significant impact on road surface settlement. Therefore, field monitoring numerical simulation are adopted in this study to analyze effect cross diaphragm (CRD) method settlement for under-construction Yüan 1 railroad...

In Buried Dreams, Andrew R. Black chronicles the largely forgotten effort of Massachusetts to surmount Berkshires and build a permanent link with interior in order retain Commonwealth’s, particularly port Boston’s economic prominence. This effort, 4.75 mile-long Hoosac Tunnel, eventually took twenty-four years, ended over one hundred lives, consumed more than $20,000,000 state funds. Born desir...

Railroad trespassers are persons on railroad property whose presence is prohibited or unlawful. Most trespassers are walking along or across railroad tracks. In 1997, fatalities to railroad trespassers became the leading cause of railroad-related deaths in the United States. In 1998, 513 persons were injured and 536 persons were killed while trespassing (Federal Railroad Administration, unpubli...

There are situations where a system in mind needs to be tested before it is built. Using modeling and simulation users can apply realistic interactions with their synthetic environments representing real world. In this study, the synthetic environment is a hardware railroad model representing a miniature of the actual size railroad. Simulation software, used to test the railroad system, consist...

The railroad industry was substantially deregulated by the Staggers Act in 1980. While railroad rates, as measured by industry-wide revenue per ton-mile, declined since that time, it is unclear why rates declined. Changes in commodity mix, length of haul, shipment size, lading weight, equipment ownership, railroad costs, competition from other modes, and demand for railroad transportation have ...
