Fast automatic microstructural segmentation of ferrous alloy samples using optimum-path forest
In this work we propose a novel automatic cast iron segmentation approach based on the Optimum-Path Forest classifier (OPF). Microscopic images from nodular, gray and malleable cast irons are segmented using OPF, and Support ...
Effect of pectins with different degrees of esterification on the absorption of non-heme iron in humans.
not clear if this effect is universal for all kind of fiber. In the case of pectin, soluble fiber present in natural and processed foods, the evidence on the effect of its esterification degree on iron absorption is ...
Potential applications of Desferrioxamine and other iron chelators for the clinical management of neurodegenerative diseases.
(Instituto de Física da Universidade de São Paulo.São Paulo, 2014-05-21)
Recently, potential applications of Desferrioxamine and other iron chelators have attracted attention for the clinicai management of neurodegenerative diseases. Several studies in the literature indicate that metal ...
Comparative study on turning CI and CGI using silicon nitride cutting tools
There has been a great interest for improving the machining of cast iron materials in the automotive and other industries. Comparative studies for tool used to machine grey cast iron (CI) and compacted graphite iron (CGI) ...
Cranberry effect on the absorption of non-heme iron.
Background: Iron deficiency anemia is a public health problem with a high prevalence in the world (~30%), especially in children and women. The iron absorption depends of dietary factors and iron stores; some foods such ...
α-SiAION: Development and machining test on gray cast iron
The α-SiAlON ceramic cutting tool insert is developed. Silicon nitride and additives powders are pressed and sintered in the form of cutting tool inserts at temperature of 1900 °C. The physics and mechanical properties of ...
Bioextraction of copper from printed circuit boards: influence of initial concentration of ferrous iron
(TMSSan Antonio, Texas, 2013)
Printed circuit boards are found in all electric and electronic equipment and are particulary problematic to recycle because of the heterogeneous mix of organic material, metals, and fiberglass. Additionally, printed ...
Electrocatalytic and voltammetric determination of sulfhydryl compounds through iron nitroprusside modified graphite paste electrode
Iron nitroprusside Fe(II)NP was incorporated into a carbon paste electrode and the electrochemical studies were performed with cyclic voltammetry. The cyclic voltammogram of Fe(II)NP exhibits two redox couple with formal ...
Iron absorption from biofortified beans evalueted by stable isotopes.
