Extractability and mobility of mercury from agricultural soils surrounding industrial and mining contaminated areas [PDF]

, 2010
This study focussed on a comparison of the extractability of mercury in soils with two different contamination sources (a chlor-alkali plant and mining activities) and on the evaluation of the influence of specific soil properties on the behaviour of the

Tobacco Analysis: Sequential Differential Solvent Extractions

Journal of AOAC INTERNATIONAL, 1974
Abstract A method is described for sequential differential solvent extraction of tobacco, using petroleum ether (38-58°C), tetrahydrofuran, acetonitrile, 95% ethanol, 20% water-dioxane, and water. The method is suitable for the monitoring of tobacco fermentation, the differentiation between cigarette and cigar filler tobaccos, and the ...

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Syndepositional Uptake of Uranium, Molybdenum and Vanadium into Modern Bahamian Carbonate Sediments during Early Diagenesis

Geosciences, 2023
Syndepositional diagenesis is a complicating factor when interpreting geochemical proxies in carbonate sedimentary environments. Previous studies have suggested that carbonate deposits may preserve the geochemical and isotopic signatures of seawater that

When Are Tree Structures Necessary for Deep Learning of Representations? [PDF]

, 2015
Recursive neural models, which use syntactic parse trees to recursively generate representations bottom-up, are a popular architecture. But there have not been rigorous evaluations showing for exactly which tasks this syntax-based method is appropriate ...

Effect of different extracting solvents on antioxidant activity and phenolic compounds of a fruit and vegetable residue flour

Scientia Agropecuaria, 2016
In order to quantify antioxidant capacity in food products, several methods have been proposed over the years. Among them, DPPH radical is widely used to determine the antioxidant capacity of different substrates.
