OBJECTIVE The aim of this study was to evaluate the relationship between carpal tunnel syndrome symptoms and compression of the median nerve at the wrist in symptomatic patients. METHODS A total of 250 patients were selected among those referred for electrodiagnostic evaluation with complaints involving hand or wrist. Primary and secondary symptoms were(More)
In this article recent advances in the Marker and Cell (MAC) method will be reviewed. The MAC technique dates back to the early 1960s at the Los Alamos Laboratories and this article starts with a historical review, and then a brief discussion of related techniques. Improvements since the early days of MAC (and the Simplified MAC – SMAC) include automatic(More)

Spatial sampling methods have acquired great popularity due to the number of applications that need to triangulate portions of space in various dimensions. One limitation of the current techniques is the handling of the final models, which are large, complex and need to register neighborhood relationships explicitly. Additionally , most techniques are(More)
A randomised controlled trial compared the effectiveness and toxicity in pulmonary tuberculosis of two drug regimens containing rifampicin and isoniazid given daily or twice-weekly for 4 months after a 2-month period of intensive treatment with daily isoniazid, rifampicin, and pyrazinamide. 667 patients with newly diagnosed pulmonary tuberculosis were(More)

We propose a novel vortex core line extraction method based on the λ 2 vortex region criterion in order to improve the detection of vortex features for 3D flow visualization. The core line is defined as a curve that connects λ 2 minima restricted to planes that are perpendicular to the core line. The basic algorithm consists of the following stages: (1) λ 2(More)

In this work, a new experiment al device to visualize the filling of containers, under controlled and reproducible conditions, is described and employed to study the various phenomen a that occur during container filling with Newtonian fluids. The experimental results displayed a variety of flow patterns, including the phenomenon of jet buckling. The(More)
