Barium Swallow A Barium swallow is a radiography contrast technique performed to visualize the esophageal portion of the Upper Gastrointestinal tract. Contrast Medium is taken orally and the lumen of the Esophagus is fluoroscopically visualized. Standard X-ray films are normally taken prior to administration of the contrast medium and these are useful in detecting perforation‚ presence of radiopaque foreign substances and gastric wall thickening. Oral contrast mediums‚ such as barium sulfate highlight

The video that I observed was an adult that was given a modified barium swallow (MBS). The adult was given thin liquids to complete the MBS. The MBS observes all stages of swallowing. The oral preparatory stage of swallowing was not clearly observed in the video. However‚ the oral transport‚ pharyngeal‚ and esophageal stages of swallowing were observed. During the oral transport stage‚ the tongue forms a groove that pushes the bolus posteriorly. However‚ it was observed that the patient’s tongue

Barium is a soft‚ heavy‚ silver-colored metal element. This element does not have very many uses outside of the laboratory‚ but it combines easily with other chemicals to form compounds used for important industrial uses. For example‚ Barium carbonate is used in the manufacture of ceramics and special glass‚ and also to purify certain chemical solutions. It is also an ingredient in clay slurries‚ also known as water muds‚ used in drilling oil wells. Barium titanate is used in sonar detectors and

Barium Research Paper Mr.Martin Block 1 May 18th‚ 2012 Abstract Barium was discovered in 1779 by Carl Scheele‚ but was isolated for the first time in 1808 by an English chemist by the name of Sir Humphry Davy. Barium is commonly found as BaSO4. Things that glow in the dark are made from Barium. Barium has many uses and plays a big role in our environment today. Barium can be found almost anywhere in the environment because it is produced there naturally and sometimes affects the environment

Every step in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must

Selective precipitation of the Barium Magnesium Group Chem 112-004 Abstract The purpose of this experiment is to separate and identify the cations of Ba+‚Sr2+‚Ca2+‚ Mg2+ and NH4+ using differences in solubility and confirming test to identify the unknown solution used in this experiment. In this experiment the methodology used by the group is to perform the tests for both the unknown and the cations (Ba+‚Sr2+‚Ca2+‚ Mg2+ and NH4+) using the known as a control for comparison and identification

Abstract The present study‚ considering Barium strontium titanate due to its important applications in the electronic device as the piezoelectric material due to excellent performance as sensing and actuation. Barium strontium titanate nanocrystalline ceramic have been synthesized from mechanical alloying of commercially available BaCO3‚ SrCO3 and TiO2 by high energy ball milling. This method has produced nano-sized particles as well as highly reactive surface‚ can cause structural relaxation of

Preparation and Ferroelectric Characterization of Calcium doped Barium Titanate ceramics ABSTRACT Barium Titanate (BT) is widely used in electro-optical and electroceramic industry because of its ferroelectric‚ thermoelectric and piezoelectric properties when it assumes the tetragonal structure. In addition to its Lead free composition‚ its perovskite structure allows variation of ionic size and small displacement of atoms that lead to the distortion of the structure which has a profound
