Fast automatic microstructural segmentation of ferrous alloy samples using optimum-path forest
(2010-05-21)
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.
(2015)
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
(2008-12-01)
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.
(2015)
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 ...
Produção de pigmentos inorgânicos a partir da solução de cloreto ferroso proveniente das linhas de decapagem contínua da CSN
(2010-12-01)
In this work is analyzed the synthesis of maghemite, γ - Fe 2O3, magnetite, Fe304, goethite, α - FeOOH, and hematite, α - Fe2O3, by application of excess of iron chlorate ionic aqueous solution from Continuous Pickling ...
Influence of adding iron-steel waste materials on hot metal quality
(2008-12-01)
Hazardous waste materials, notably industrial ones, are of particular concern, inasmuch as if they are not dealt with adequately, they may pose a serious threat to the environment. In this connection, those industries which ...
α-SiAION: Development and machining test on gray cast iron
(2008-12-01)
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 ...
Determination of iron(II) concentration by potentiometric titration of chromatometry with TICl2 reduction step without heating
(2012-12-01)
The objective of this work was to improve the method for determining the concentration of iron in accordance with standard ISO 9507: 1990 by potentiometric titration using automated chromatometry using a combined platinum ...
