Figure 1: Left: three dimensional scheme of the phantom used for MRI experiments. Center tube is filled with PHIP substance (orange), outer tube contains water (blue). Right: the FIDs originating from the whole phantom. The blue signal stems from thermally polarized water and thermally polarized PHIP substanc. The red signal is generated by thermally polarized water and hyperpolarized PHIP subs...

This experimental study is intended to explore the heat performance of a novel vacuum tube heat collector with thermal storage. In order to enhance the heat transfer performance, we add radial metal fins to the U-tube which is used as the heat transfer channel of water. Meanwhile, in order to increase the thermal capacity of the heat collector, the heat collector model is designed to be larger ...

A simple, convenient, reusable, and inexpensive airand water-purification unit including a one-end sealed porous amorphous-silica (a-silica) tube coated with TiO2 photocatalyst layers has been developed. The porous a-silica layers were formed through outside vapor deposition (OVD). TiO2 photocatalyst layers were formed through impregnation and calcination onto a-silica layers. The resulting por...

This paper presents the application of finite element method (FEM) to analyze the tube temperature distribution in a water tube boiler. Two-dimensional (2-D) finite element models are developed where the axi-symmetric triangular elements for the cross section area along the water tube are applied in computer software namely MSC Patran-Nastran. The analysis of the temperature distribution for ev...

This letter was referred for comment to Becton Dickinson and Co. For the four analytes for which Dr. Steindel found differences, they also found “clinically insignificant” differences. They comment farther: “We also extracted the contents of the tube with distilled water and determined calcium and LDH. The range of calcium extracted from the tube measured by atomic absorption [spectroscopy] was...

BACKGROUND Tympanostomy tube insertion is one of the most commonly performed pediatric procedures in the United States. In an effort to reduce the incidence of postoperative otorrhea, many surgeons have traditionally recommended strict avoidance of water exposure to the ears. A number of studies have questioned the efficacy of such recommendations. Here we examine the evidence regarding water p...

Extended-spectrum β-lactamase (ESBL)-producing Enterobacteria has become a considerable global concern because of their potential dissemination in humans, in domestic animals, wildlife and the environment. The present study aimed to explore the ESBL producing  enterobacteria in aquatic sources of Bangladesh as the water may be the potential source of dissemination of this alarming ant...

background : microbial monitoring of aquatic sources is essential in the correct management of these vital sources. multiple tube fermentation (mtf) technique is currently used for assessment of the microbial quality of water sources. however, today enzymatic assay has been presented as an alternative approach for detecting indicator bacteria. the purpose of this study was to compare enzymatic ...
