OBJECTIVE We compared the clinical efficacy of barium therapy and conservative therapy in preventing recurrence in patients with diverticular bleeding. BACKGROUND Previous case reports have indicated that barium impaction therapy provides initial hemostasis for diverticular bleeding and prevention against rebleeding. METHODS After spontaneous cessation of bleeding, patients were randomly as...
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...
We present an experimental study of coherent collisions between one-dimensional bright photorefractive screening solitons in a bulk strontium barium niobate crystal.
The set of orbital elements available for chemically-peculiar red giant (PRG) stars has been considerably enlarged thanks to a decade-long CORAVEL radial-velocity monitoring of about 70 barium stars and 50 S stars. When account is made for the detection biases, the observed binary frequency among strong barium stars, mild barium stars and Tc-poor S stars (respectively 35/37, 34/40 and 24/28) is...
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...
