The relative sensitivity of barium swallow examination

Indian Journal of Otolaryngology and Head and Neck Surgery, 2002
In all the cases of P.V Syndrome, it is better to find out by endoscopy even if barium swallow is normal. Thus in P. V. syndrome, the accuracy of barium swallow is only 19% and 81% are reported as false negative.In strictures and malignancies, the level of lesion reported by barium swallow should not be relied upon in all the cases, and they should be ...

Proposal for a Quad-Elliptical Photonic Crystal Fiber for Terahertz Wave Guidance and Sensing Chemical Warfare Liquids

Photonics, 2019
A porous-core photonic crystal fiber based on a cyclic olefin homopolymer (Zeonex) is proposed; it shows high birefringence, high core power fraction, low losses, and near-zero flat dispersion. The fiber’s core was designed with quad-elliptical (QE)

Room temperature sensing of alcohol vapours using novel radially aligned nanorutile titania

Sensors and Actuators Reports, 2023
1D nanostructures of TiO2 have been extensively researched in chemical sensing. The need for deployment of 3D nanostructures such as flower-like and urchin-like morphology for chemical sensing is very essential.

The Relative Sensitivity of Formability to Anisotropy [PDF]

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">This work compares the relative importance of material anisotropy in sheet forming as compared to other material and process variables. The comparison is made quantitative by the use of normalized dependencies of depth to failure (forming limit is reached) on various measures of anisotropy, as well as strain and ...
