Methionine to cystine ratio in the total sulfur amino acid requirements and sulfur amino acid metabolism using labelled amino acid approach for broilers
(2018-11-22)
Background: Assuming that part of Methionine (Met) is converted into Cystine (Cys), but ignoring the rates with which such phenomenon occurs may lead to an excessive supply of Met in poultry diets. Such inconvenient could ...
Stable isotopes (carbon, nitrogen, sulfur), diet, and anthropometry in urban Colombian women: Investigating socioeconomic differences
(Wiley, 2014-10)
Objectives: We conducted stable isotope and dietary analyses of women from higher and lower socioeconomic status (SES) groups in Cali, Colombia. The objectives were to test between-group differences in stable isotope, ...
Isotope determination of sulfur by mass spectrometry in soil samplesDeterminação isotópica de enxofre por espectrometria de massas (irms) em amostras de solo
(Sociedade Brasileira de Ciência do Solo, 2012)
Sulphur plays an essential role in plants and is one of the main nutrients in several metabolic processes. It has four stable isotopes (32S, 33S, 34S, and 36S) with a natural abundance of 95.00, 0.76, 4.22, and 0.014 in ...
Formation of giant iron oxide-copper-gold deposits by superimposed, episodic hydrothermal pulses
(Springernature, England, 2021)
The Candelaria iron oxide-copper-gold deposit in Chile was formed by superimposed, episodic hydrothermal pulses with contrasting composition and temperature, according to micro-textural and compositional variations in ...
Fluid Inclusion and stable isotope studies at Don Sixto, a precious metal low sulfidation deposit in Mendoza province, Argentina
(Wiley, 2013-09)
The Don Sixto mining area in Mendoza province, central-western Argentina, contains an epithermal low sulfidation Au–Ag deposit. It is a small deposit (∼4 km2), with a gold resource of 36 t. In Don Sixto, ore minerals are ...

A genetic link between magnetite mineralization and diorite intrusion at the El Romeral iron oxide-apatite deposit, northern Chile
(Springer Verlag, 2018)
El Romeral is one of the largest iron oxide-apatite (IOA) deposits in the Coastal Cordillera of northern Chile. The Cerro Principal magnetite ore body at El Romeral comprises massive magnetite intergrown with actinolite, ...
Isotopic studies in Pacific Panama mangrove estuaries reveal lack of effect of watershed deforestation on food webs
(Elsevier, 2015-02)
Stable isotopic N, C, and S in food webs of 8 mangrove estuaries on the Pacific coast of Panama were measured to 1) determine whether the degree of deforestation of tropical forests on the contributing watersheds was ...
Stable Isotope Analysis of the Inca Mummy from Nevado de Chuscha (Salta, Argentina)
(Wiley Blackwell Publishing, Inc, 2020-08)
This paper presents the carbon (13C/12C), nitrogen (15N/14N), oxygen (18O/16O), hydrogen (2H/1H) and sulfur (34S/32S) stable isotope values measured in the hair of a female individual from north-western Argentina. The ...
