Occurrence of major and trace elements in powdered milk from Argentina
(Wiley Blackwell Publishing, Inc, 2019-06)
The concentrations of major and trace elements in Argentinean commercial powdered milk samples were determined with inductively coupled plasma mass spectrometry. Also the daily intake (DI) was calculated for adults and ...
Extremal elements of a sublattice of the majorization lattice and approximate majorization
(IOP Publishing, 2020-04)
Given a probability vector x with its components sorted in non-increasing order, we consider the closed ball B p ǫ (x) with p > 1 formed by the probability vectors whose ℓ p -norm distance to the center x is less than or ...
Distribution of major elements in Atlantic surface sediments (36 degrees N-49 degrees S): Imprint of terrigenous input and continental weathering
(Amer Geophysical UnionWashington, 2012)
Numerous studies use major element concentrations measured on continental margin sediments to reconstruct terrestrial climate variations. The choice and interpretation of climate proxies however differ from site to site. ...
Spatial and vertical distributions of elements in sediments of the Colorado River delta and upper Gulf of California
(Marine Chemistry, 2002)
The abundance of major components (Fe, Ca, K, and organic carbon) and trace elements was analyzed in surface sediments and core samples from the Colorado River delta (CRD) and the Upper Gulf of California (UGC) using ...
Biomagnification of mercury and selenium in Blue Shark Prionace glauca from the Pacific Ocean off Mexico
(Biological Trace Element Research, 2011)
The aim of this study was to determine the biomagnification of mercury through the principal prey of the blue shark, Prionace glauca, off the western coast of Baja California Sur, Mexico, as well as the relationship between ...
