Accurate line profiles at several phases have been obtained from spectra of Theta Aurigae taken with the Canada-France-Hawaii Telescope. These have been used to construct maps of the surface distributions of Fe, Cr, and Si by solving the inverse problem. Rather complex structures are found, wit...
Five transects of the Clyde Estuary were carried out between August 1989 and March 1991, always during the last 2 h of the flood tide. The following water-column properties were examined: dissolved, leachable particulate and detrital particulate trace elements (Fe, Mn, Zn, Pb, Cd, Co, Cu,...
Although the fine fraction has a different particle size in almost every study, a comparison of these fractions with the coarser, sorted fractions of the same studies reveals that the fine fractions often contain considerably higher concentrations of specific chemical elements (Viczek et al., 2020...
A theoretical investigation, on the basis of the two-dimensional MHD approximation, of the effect of the distribution of the RLC components of a capacitative energy storage unit on the nature of plasma flow in a coaxial channel is presented. An analysis of variations of the dimensionless parameter...
This study was carried out in a river catchment in southern Italy to determine some possible relationships between the distribution of chemical elements and size fractions in stream sediments. Through the presence of variations in concentration of some elements in each size fraction, it was possible ...
The observed partition patterns of elements between a marine solid phase (e.g., pelagic clays, deep sea manganese nodules, seamount manganese crusts, and plankton) and seawater can be, to the first approximation, explained by the James and Healy adsorption model, except for Ce, Co, Mn, Pb,...

Estimates of the concentration of the these heavy elements are given and correlation analysis has been performed indicating that most of these elements seem to appear at the surface of the fly-ash particles. 展开 关键词: micro-XRF micro-XRD synchrotron radiation capillary optics fly-ash particles ...
We simulate light curves of the helium strong chemically peculiar star HD 37776 assuming that the observed periodic light variations originate as a result of inhomogeneous horizontal distribution of chemical elements on the surface of a rotating star. We show that chemical peculiarity influences the mon...
