TL;DR: It is demonstrated that laser capture microdissection coupled with X-ray fluorescence microscopy can be applied to determine elemental profiles (S, Fe, Cu, and Zn) in Abeta amyloid plaques and provided further evidence that both metals (such as Cu) and H(2)O( 2) promote formation of neurotoxic Abeta oligomers.

TL;DR: A tropical precipitation record from the Southern Hemisphere covering the past 282,000 years is presented, inferred from a marine sedimentary sequence collected off the eastern coast of Papua New Guinea, suggesting that the obliquity forcing may play a more important role in global hydroclimate cycles than previously thought.

TL;DR: In this paper, the authors obtained raw coal and ash samples from three power plants; analyzed the enrichment and concentration of trace elements Pb, Zn, Th, Cu, As, V, Cl, and F in coal ashes; and studied petrological and mineralogical characterizations and the chemical composition of coal ashes.

TL;DR: In this article, the mineral and chemical compositions and some trace element contents (As, Ba, Cr, Mn, Mo, Sb, Th, U and V) in coal and coal ash samples from the Huaibei coal field in China were studied.

TL;DR: In this paper, the distribution and concentration of sulfur in the Yanzhou mining district are analyzed, and the forms of sulfur are studied, including pyritic, organic and sulfate sulfur.
