Trace element abundances in clinopyroxene (cpx) from cumulate xenoliths are used to characterize the nature of primitive magma-forming processes beneath the Aleutian island arc. Clinopyroxenes from deformed mafic and ultramafic xenoliths hosted in a Neogene-age mafic sill from Kanaga Island have widely varying trace element abundances (Sr=8–32, Y=2–64, Zr=2–38, Nd=0.65–16 ppm) that are generall...

Ocean acidification (OA) is not an isolated threat, but acts in concert with other impacts on ecosystems and species. Coastal marine invertebrates will have to face the synergistic interactions of OA with other global and local stressors. One local factor, common in coastal environments, is trace element contamination. CO2 vent sites are extensively studied in the context of OA and are often co...

Discriminant analysis of 16 trace element levels measured by ultramicro energy dispersive X-ray fluorescence in malignant and histologically normal human breast, colon, and lung tissues is shown to be a potentially valuable methodology for making malignant-normal and tis sue-type classifications. Linear composites of trace elements producing optimal malignantnormal discriminations are found to ...

Artifacts are the nemesis of trace element analysis in electron-excited energy dispersive X-ray spectrometry. Peaks that result from nonideal behavior in the detector or sample can fool even an experienced microanalyst into believing that they have trace amounts of an element that is not present. Many artifacts, such as the Si escape peak, absorption edges, and coincidence peaks, can be traced ...

Title of Document: AN ANALYTICAL APPROACH FOR FATIGUE LIFE ESTIMATION OF COPPER TRACES FOR DESIGN OPTIMIZATION IN ELECTRONIC ASSEMBLIES. Sandeep Menon, Doctor of Philosophy, 2015 Directed By: Professor Michael G. Pecht, Department of Mechanical Engineering This dissertation investigates the durability of the copper traces using experimental results from a fully reversed four point bend test and...

Any deficiency in trace element content of commercial poultry diets will decrease their performance. To prevent this situation it is necessary to supplement trace minerals in poultry diets to allow the modern birds to reach their genetic potential. The NRC publication as the most famous reference for livestock and poultry nutrients requirement has no recommendation for some less needed trace mi...

We quantified leaching and mass fractions of trace elements in melted acidified ice core samples measured by Inductively Coupled Plasma Sector Field Mass Spectrometry (ICP-SFMS). This assessment was conducted using nine ice core sections retrieved from various high-altitude drilling sites in South America, Africa, Asia and Europe. Twenty trace elements (Ag, Al, As, Bi, Cd, Co, Cr, Cu, Fe, Mn, M...
