VAPOR PRESSUREX-RAY DIFFRACTIONA wealth of information about the structure of porous materials is contained in the experimental data of mercury intrusion and retraction obtained from mercury porosimetry. Proper interpretation of such data requires the use of a model capable of describing the phenomena ...
Mercury (Hg) concentrations and isotope ratios in sediments are widely used as a proxy for volcanic activity in stratigraphic successions (see review by Grasby et al.12, Supplementary Notes1–3). Volcanogenic emissions, the largest natural Hg source, supply Hg to the atmosphere with a residence...
Results: The visual acuity less than two lines in ETDRS chart in 7(9.7%) patients, color vision impairment in 6(8.3%) patients were determined with ophthalmic examination. There were a significant difference in the color confusion index of patients, (p<0.05). The mean parametric VF values ...
