The key aspect of minimizing the descent of quality and productivity in papermaking is to identify the origins of scale and to realize the appropriate treatment. Scale derived from calcium, silicon and aluminium is most commonly reckoned and easily collected. In the present study, we focus our attention on another serious situation of such adherent scale as barium sulfate, of which boil-out tre...

OBJECTIVE The aim of this study was to review the radiological findings of three cases of total colon aganglionosis (TCA), hypoganglionosis, and immature ganglionosis, and to compare the differences in diagnosis and follow-up of these three disease entities. MATERIALS AND METHODS Three neonates with neonatal onset of abdominal distension with vomiting were investigated, and the cases were dia...

SUMMARY. The timed barium esophagogram (TBE) is a further development of the barium swallow, introducing functional and dynamic dimensions to the assessment. The purpose of our study was to assess the day to day variability of TBE parameters when scored in healthy subjects, in untreated and in previously treated patients with confirmed diagnoses of achalasia and to assess the intra- and interob...

Various compositions of barium-doped hematite between pure hematite (α-Fe₂O₃) and pure barium hexaferrite (BaFe12O19) were synthesized by solid state reaction. The XRD analyses confirmed the progressive evolution of the two crystalline phases. Tests as humidity sensors show that the electrical resistance of samples containing high proportions of hexaferrite phase is strongly influenced. Electro...

OBJECTIVE The purpose of our investigation was to determine the usefulness of barium studies for differentiating benign and malignant strictures of the esophagus. MATERIALS AND METHODS A search of radiology and endoscopy files revealed 100 patients with esophageal strictures on barium studies who underwent endoscopy (with endoscopic brushings or biopsy specimens in 57). The images from these ...

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...

Taking the total angular momentum conservation in place of the tangential momentum conservation, and considering the square and higher power terms of orbital eccentricity e, the changes of orbital elements of binaries are recalculated for wind accretion scenario. These new equations of orbital elements are used to calculate the properties of barium stars. Our results show that, during the evolu...

• The effect of barium ion on the electrical and mechanical activity of the heart has been reported by many investigators." The production of various degrees of heartblock, idioventricular rhythm, extrasystoles, tachycardia and fibrillation have been observed." Boehm noted in 1875 that the barium ion in small doses, 10 to 30 mg/kg, increased the work of the frog's heart without changing its fre...

BACKGROUND Acute lower gastrointestinal hemorrhage originating from the appendix is rare and often intractable, because it is almost impossible to approach the bleeding point by endoscopy. We herein describe the first case of bleeding from the appendix, which was successively controlled by a therapeutic barium enema administered into the appendix. CASE PRESENTATION A 71-year-old male visited ...

Although it has been known for more than a century that plants are able to extract appreciable amounts of the relatively insoluble compounds of barium contained in soils, very little scientific investigation has been made to determine whether or not the compounds of this element have any specific function in the vegetable economy. Because compounds of barium are poisonous when taken into the an...
