The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intesti...

OBJECTIVES To compare the efficiency of the subannular T-tube (SAT) vs that of the repetitive transtympanic Duravent tube (TTT) in children with recurrent or chronic otitis media (OM) with effusion or tympanic membrane retraction and to establish which population would be more likely to benefit from TTTs vs SATs. DESIGN Medical record review. SETTING Tertiary care pediatric center. PATIEN...

Thin-walled tube bending is still to be considered a new and advanced technique. The process has been adopted into several industries such as aero and automotive. This process may produce a wrinkling, bulking and tearing phenomenon if the process parameters are inappropriate, especially for tubes with large diameter and thin wall thickness. Push bending process is one of the methods used for be...

The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...

Abstract Obtaining quality air temperature measurements in complex mesoscale environments, such as thunderstorms or frontal zones, is problematic, and particularly challenging from a moving platform. For some time mobile weather platforms known Mobile Mesonets (MMs) have used custom aspirated shields. The original design was the “J-Tube”, which addresses but not all of unique problems associate...

In this numerical study, the heat transfer performance of shell-and-tube exchangers (STHXs) has been compared for two different tube arrangements. STHX having 21 and 24 tubes arranged in inline staggered grid considered analysis. Shell-and-tube exchanger with arrangement observed to provide lesser thermal stratification as arrangement. Further, study variation mass flow rate shell-side fluid co...

abstract objective neural tube defects including anencephaly, encephalocele, and spina bifida are major congenital malformations with multifactorial etiology, and with a great variation in their prevalence in different populations. the study on the prevalence of these malformations may be helpful in planning strategies for their prevention. the aim of this epidemiologic descriptive study was to...

A critical challenge to translating field effect transistors into biochemical sensor platforms is the requirement of a gate electrode, which imposes restrictions on sensor device architectures and results in added expense, poorer scalability, and electrical noise. Here we show that it is possible to eliminate the need of the physical gate electrode and dielectrics altogether using a synthetic t...

The tube model, realized by lattice filters in discrete time, can be used to describe the propagation of plane sound waves through the vocal tract. The tube model which is treated in this contribution contains two prescribed terminations. One for the lip opening and one for the constriction at the glottis. These two terminations are frequency dependent and the lip termination must be adapted to...

Ascaris lumbricoides is one of the most common human helminthic diseases worldwide. On ultrasound, it is seen as linear non-shadowing echogenic structures with target appearance in cross section, and the live worm may show writhing movements in real time. On barium meal follow through, it appears as radiolucent tubular filling defects within the bowel lumen. Though not sensitive, direct real-ti...
