THUNDERSTORM GUSTS COMPARED WITH COMPUTED DOWNDRAFT SPEEDS

The Accuracy of Ultrasonography in Compared with Computed Tomography in Detection of Anterior Mediastinal Neoplasms

Abstract Background The aim of this study was to evaluate sensitivity and specificity of mediastinal sonography, and compared with CT, in detection of anterior mediastinal neoplasms. Materials and Methods The sonography with convex probes (5.0 and 7.5 MHz) was done prospectively for 34 patients (from 2 to 25 years old) with mediastinal mass. The results were compared with the results of ...

Gusts , Discrete and Indiscrete

2 Probabilistic Description of Wind Gusts

Velocity measurements of wind blowing near the North Sea border of Northern Germany and velocity measurements under local isotropic conditions of a turbulent wake behind a cylinder are compared. It is shown that wind gusts – measured by means of velocity increments – do show similar statistics to the laboratory data, if they are conditioned on an averaged wind speed value. Clear differences bet...

Computed Structures of Twist Boundaries Compared with Tem Observations

The structure of (111) twist boundaries in f.c.c. metals is investigated by computer simulation. For coincidence orientations in the vicinity of the twin orientation a characteristic six-star pattern has been found, in agreement with TEM observations on dislocation networks in nearcoherent twin boundaries in Au. Dislocation networks in near-coherent twin boundaries in Au have recently been stud...

Performance of multidetector computed tomography colonography compared with conventional colonoscopy.

BACKGROUND AND AIMS This was a prospective blinded study to compare computed tomography (CT) colonography, performed with multidetector arrays CT scan (MDCT), with conventional colonoscopy for the detection of colorectal neoplasia. METHODS Fifty patients were examined by MDCT after standard bowel preparation and rectal air insufflation in the supine and prone positions. Data sets were examine...
