The spectral functions for calcium and argon are constructed. It is verified that their predictions for the quasielastic electron-nucleus cross sections in the energy range ∼1 GeV agree with the data. The argon spectral function is then used to obtain the quasielastic neutrino-nucleus cross section.
The caging effect of the host environment on photochemical reactions of molecular oxygen is investigated using monochromatic synchrotron radiation and spectrally resolved fluorescence. Oxygen doped clusters are formed by coexpansion of argon and oxygen, by pickup of molecular oxygen or by multiple pickup of argon and oxygen by neon clusters. Sequential pickup provides radially ordered core-shel...
Poultry fillets were packaged under 6 different gas atmospheres (A: 15% Ar, 60% O2, 25% CO2; B: 15% N2, 60% O2, 25% CO2; C: 25% Ar, 45% O2, 30% CO2; D: 25% N2, 45% O2, 30% CO2; E: 82% Ar; 18% CO2; F: 82% N2, 18% CO2) and stored at 4°C. During storage, the growth of typical spoilage organisms (Brochothrix thermosphacta, Pseudomonas spp., Enterobacteriaceae, and Lactobacilli spp.) and total viabl...
Hemorrhagic radiation cystitis is an example of a typical radiotherapy-induced adverse event. However, the optimal treatment for hemorrhagic radiation cystitis is not known. There are limited data regarding the use of argon plasma coagulation for hemorrhagic radiation cystitis. Here, we present the use of argon plasma coagulation using a gastrointestinal endoscope to treat hemorrhagic radiation...
Although the approach using non-thermal plasma (NTP) for deNOx has been studied for over 15 years, how to achieve higher removal efficiency with lower cost is still a barrier for its industrial application. In order to investigate the impact of the argon additive on electron density, energy and nitric oxide reduction process in plasma, the spectrum of the dielectric barrier discharge at atmosph...
PURPOSE The purpose of this descriptive scanning electron microscopic study was to characterize surface alterations in primary tooth enamel after in vitro argon laser irradiation alone and combined with topical fluoride treatment either before or after argon laser irradiation. METHODS Twenty extracted or exfoliated primary teeth underwent soft tissue debridement and a fluoride-free prophylaxi...
