A case of a 63-year-old man with small bowel ischemia six weeks after transplantation surgery is presented. Plain abdominal radiograph obtained several days after ingestion of barium shows the sign of prolonged barium coating indicating severe mucosal damage. Abdominal CT scan demonstrates small bowel wall thickening as well as pockets of peritoneal fluid collections. Most critically, CT allows...

A sequential injection analysis (SIA) system for the simultaneous determination of nitrite, nitrate, sulphate and phenolic compounds, in wastewaters has been developed. The nitrite determination is based on the Griess-Llosvay reaction. Nitrate is previously reduced to nitrite in a copperized cadmium column and analyzed as nitrite. The sulphate determination is based on the turbidimetric determi...

The electronic structures of four semiconductor compounds BaCu2S2, BaCu2Se2, BaAg2S2, and BaAg2Se2 are studied by density functional theory using both semi-local and hybrid functionals. The ionization energies and electron affinities were determined by aligning the electronic states with the vacuum level by calculating the electrostatic profile within a supercell slab model. The ionization ener...

*Financial sponsoring – none Contrast barium enema is a 60-200% solution of barium sulphate, administered rectally. It is used not only in the diagnostics of colorectal diseases, but also as a therapeutic option in case of intussusception or treatment of lower gastrointestinal tract bleeding. The latter indication raises most controversies amongst surgeons. Opponents argue that 7080% of cases o...

herein, we present the case of a 45-year-old woman with pulsion and midesophageal diverticula, who had complaints of dysphagia and regurgitation. diagnosis was confirmed by endoscopy and barium swallow. the patient underwent right posterolateral thoracotomy with excision of diverticula and repair of the muscular layer along the site of diverticula. five days following the operation, barium swal...

We study sympathetic cooling of the radial ion motion in a linear RF trap mixed barium-ytterbium chains. Barium ions are Doppler-cooled, while ytterbium cooled through their interaction with cold barium ions. estimate efficiency by measuring average occupation quantum numbers, and thus temperature, all normal modes chain. The full set orderings chain two have been probed, we show that thermal n...

Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium hexaferritefine particles is influenced by mo...
