1. Prevention of barium sulfate deposition in a D (Chlorine Dioxide) - stage : a chemical model
Sammanfattning : .... LÄS MER
2. Spectroscopic Studies of the Elements Ba, Fe, Ga, In and Ru
Sammanfattning : New measurements of the elements Ba, Fe, Ga, In and Ru are reported. The analysis of barium contains new wavelengths, improved energy level values and new values of the ionization limit in both Ba I and Ba II. Oscillator strengths and radiative lifetimes in Fe II, as a part of the FERRUM project, are reported. LÄS MER
3. Catalytic combustion of methane
Sammanfattning : Catalytic combustion is an environmentally benign technologywhich has recently reached the stage of commercialization.Palladium is the catalyst of choice when considering gasturbines fuelled with natural gas because of its superioractivity for methane oxidation. LÄS MER
4. Radium and Barium Co-precipitation A Pre-study
Sammanfattning : .... LÄS MER
5. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia
Sammanfattning : In idiopathic achalasia, degeneration of the inhibitory innervation of the esophageal smooth muscle results in absence of primary peristalsis and in incomplete relaxation of the lower esophageal sphincter (LES). All treatments for achalasia aim at reducing the pressure gradient across the LES, thus facilitating esophageal emptying by gravity. LÄS MER
