TL;DR: In this article, a quasi-spherical, noble-gas-filled cavity was designed to determine the thermodynamic temperature of the gas from measurements of the frequencies and the halfwidths of microwave and acoustic resonances in the cavity.
Abstract: We describe a quasi-spherical, noble-gas-filled cavity designed to determine the thermodynamic temperature of the gas from measurements of the frequencies and the half-widths of microwave and acoustic resonances in the cavity. The quasi-spherical shape retains the advantages of spherical acoustic resonators (non-degenerate, radially symmetric acoustic modes, negligible viscous damping at the boundary) while simplifying the determination of the cavity's thermal expansion using microwave resonances. As a specific example, we consider a cavity bounded by four quadrants of a perfect sphere of radius a connected to each other by narrow cylindrical sections of thickness 21a and 22a, where 1 and 2 are of the order of 10−3. The cylindrical sections split the degenerate microwave triplets (TM11, TE11, TM12, etc) into three easily resolved components with predictable orientations. Preliminary measurements show that two judiciously located microwave probes excite and detect all three components of each microwave triplet with approximately equal amplitudes. We discuss the placement of acoustic transducers and the dimensions of ducts that admit gas from a manifold into the cavity. Corrections were made to this article on 14 June 2004. The corrected electronic version is identical to the print version. The corrections are in the first two paragraphs of section 5.2 and in table 6.

TL;DR: In this article, a geoelectrical tomography was used to infer the presence of ice and to interpret electrical stratigraphies in order to test whether or not the internal structure of these landforms can be used for the reconstruction of recent permafrost and glacier evolution, and the results indicated that internal structures of rock glaciers and recent-deglaciated slopes can store the different climate-related episodes occurred in a specific area, such as those linked to the shifting between glacial to criotic condition and vice versa.

TL;DR: Both the production of 7alpha-hydroxysteroids and their interference with the activation of cortisone into cortisol are basic to the concept of native anti-glucocorticoids efficient at their production site.

TL;DR: After 2 years of supplementation, biochemical indicators of vitamin and trace element status reach reasonable level without reaching concentrations as high as those observed in intervention studies, which tested relatively high doses of antioxidants, and ended up with higher risk of pathology.

TL;DR: It was showed that a 7 day amoxicillin treatment did not alter the counts of Bifidobacterium, however amoxichill can have an impact by changing the microbiota at the species level and decreased the diversity of this population.
