BACKGROUND Barium swallow is performed following esophagectomy to evaluate the anastomosis for detection of leaks and to assess the emptying of the gastric conduit. The aim of this study was to evaluate the reliability of the barium swallow study in diagnosing anastomotic leaks following esophagectomy. METHODS Patients who underwent esophagectomy from January 2000 to December 2013 at our inst...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
glass ampules was identified as barium sulfate crystals by using scanning electron microscopy and energy dispersing X-ray analysis. Barium sulfate crystals isolated from these solutions occurred as single or agglomerated crystals which were 0.5-2.0 ƒÊm long in maximum dimension. Barium sulfate crystal formation in usual ampules tended to increase with increasing temperature of sterilization, bu...
the influences of anionic sodium dodecylsulfate (sds) and cationic hexadecyltrimethylammonium bromide (htab) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited cofe-bafe12o19 composite thin films were studied. sulphate bathes with natural ph containing 0 to 2 g/l surfactants were used for electroplating at room temperature. field emissi...
• Sodium is essential for lead-barium glass forming. Previous chemical analysis of ancient underestimates the sodium content. Opaque cannot be produced during primary production. Lead-barium can by mixing natron with lead and barium minerals. appeared late Warring States period in China (457 - 221 BCE) was considered as a Chinese invention due to unique presence high barium. There no indication...
We identify contributions to the valence band of the nanosized BaFe12−2xCoxTixO19 barium ferrite particles, from the cobalt and titanium dopants. Resonant photoemission results show that cobalt and titanium dopants strongly hybridize with the barium ferrite matrix. Fano resonances are identifi ed in the valence band region, at the Ba (5s), Ti (3p) and Co (3p) thresholds, and there are signifi c...
In intussusception in early childhood, reduction by barium enema is the treatment of choice. In late cases when there is air and fluid distension of the small bowel on plain x-ray, barium enema is less useful. Generally 20-25% of childhood intussusception presents in this way. We have reviewed the experience of 65 intussusceptions at the Royal Belfast Hospital for Sick Children over the past 5 ...
