This article, dealing with the intermediate-mass elements Na to Ca, is the first in a series describing the comprehensive re-determination of the solar composition. In this series we severely scrutinise all ingredients of the analysis across all elements, to obtain the most accurate, homogeneous ...
Elemental composition of the lunar surface: Analysis of gamma ray spectroscopy data from Lunar Prospector 来自Wiley 作者TH Prettyman,JJ Hagerty,RC Elphic,WC Feldman,DJ Lawrence...摘要 [1] Gamma ray spectroscopy data acquired by Lunar Prospector are used to determine global maps of the elemental ...
The elemental composition of suspended particles from the Yellow River is similar to those of the loess terraces and the world's average soils. The contents of Zn, Cu, Ni, Co and Pb in the suspended particles are higher in the Yangtze River than in the Yellow River, indicating pollution in...

Measurements made by a natural gamma ray tool are used to provide an elemental composition of an earth formation. Additional measurements made with a pulsed neutron tool with two or more gamma ray detectors are used to provide a mineralogical and/or elemental image of the formation. This may be...
Bird eggshells contain a large amount of inorganic matter, mainly calcium carbonate, as well as a small amount of organic matter and water. Changes in the elemental composition of the eggshell can affect its quality and are often related to feeding strategy due to maternal effects, which are pa...
The specific elemental impurities of concern should be 276 assessed based on knowledge of the composition of the components of the manufacturing 277 equipment. The assessment of this source of elemental impurities is one that can be 278 utilized potentially for many drug products using similar ...
