The objective of this work was to estimate patient doses (dose-area product, organ dose, effective dose and entrance surface dose) for barium procedures. A total of 175 procedures, in 175 patients, for five different examination categories was analysed. Dose-area product was determined using a transmission ionization chamber. Organ dose and effective dose were assessed using a knowledge of the ...

In this work, the inductively coupled plasma etching technique was applied to etch the barium titanate thin film. A comparative study of etch characteristics of the barium titanate thin film has been investigated in fluorine-based (CF4/O2, C4F8/O2 and SF6/O2) plasmas. The etch rates were measured using focused ion beam in order to ensure the accuracy of measurement. The surface morphology of et...

The International Programme on Chemical Safety (IPCS), established in 1980, is a joint venture of the United Nations Environment Programme (UNEP), the International Labour Organization (ILO), and the World Health Organization (WHO). The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, ...

The influence of the ferroelectric domain structure of BaTiO3 on the photochemical reactions that occur on its surface has been examined using atomic force microscopy. Both the photochemical reduction of aqueous silver cations and the oxidation of steric acid thin films were studied. During reduction, silver selectively deposits on the surface in patterns determined by the ferroelectric domain ...

Hepatic proteolysis is inhibited by cell swelling following a variety of experimental manoeuvres, such as reduction of extracellular osmolarity, concentrative uptake of amino acids, or blockade of K+ channels by barium. On the other hand, proteolysis is known to be accomplished by pH-sensitive lysosomal proteases. Accordingly, NH3/NH4+ inhibits proteolysis by intralysosomal alkalinization. The ...

Ïntussusception is the most common cause of intestinal obstruction in children. Disease in typic form manifests itself by colic abdominal pain and episodic vomiting with bloody stool. Ïn Ïleoileal types, manifestations may not be typical. Diagnosis is based on clinical finding through barium enema and sonography. Treatment is nonsurgical reduction, and if contraindicated, surgical reduction. ...

One of the common problems in children and specially in infants is gasteroesophageal reflux (G.E.R). Present study was performed to compare diagnostic value of lower esophageal sonography with barium swallow. This study was conducted on 50 patients 1 month to 15 years age in center of pediatric clinic of Tehran, during the years 1999-2000. Patients suspected to have G.E.R studied with lower eso...
