On the existence of stable population in life cycle models
(Elsevier Science Sa, 2016-01)
A common assumption adopted in life cycle general equilibrium models is that the population is stable at steady state, that is, its relative age distribution becomes constant overtime. An open question is whether the ...
Stable isotopes, carbon-14 and hydrochemical composition from a basaltic aquifer in São Paulo State, Brazil
(2017-02-01)
The Cretaceous Serra Geral Aquifer (SGA) is contained within one of the largest continental flood basalts in the world, reaching a thickness up to 1700 m in the center of the Paraná Basin. The SGA is one of the most important ...
Age estimation methods in the marine gastropod Buccinanops globulosus comparing shell marks and opercula growth rings
(Taylor & Francis As, 2016-09)
Age determination in gastropods is an essential tool for understanding the main aspects of population dynamics that allow for the formation of fisheries policies. Small-scale fisheries of the nassariid gastropod Buccinanops ...
Traceability of animal byproducts in quail (Coturnix coturnix japonica) tissues using carbon (13C/12C) and nitrogen (15N/14N) stable isotopes
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2007-12-01)
Consistent information on meat products consumed by the public is essential. The technique of stable isotopes is a powerful tool to recover consumers' confidence, as it allows the detection of animal byproduct residues in ...

The Don Sixto mining project: A low sulphidation Au-Ag deposit 5-08 of Permian-Triassic age, Mendoza, Argentina, mineralogy, fluid inclusions, stable isotopes and 40Ar/39Ar age results
(Istituto Nazionale Di Oceanografia E Di Geofisica Sperimentale, 2013-11)
It is described the ore mineralogy, fluid inclussion study, stable isotopes results and 40Ar/39Ar age determination of the Don Sixto, a low-sulphidation epithermal ore deposit from southern Mendoza.
Stable isotopes on jumbo squid (Dosidicus gigas) beaks to esitmate its trophic positon: comparison between stomach contents and stable isotopes
(Journal of the Marine Biological Association of the United Kingdom, 2006)
Stomach contents and carbon (C) and nitrogen (N) stable isotope analysis were used to evaluate trophic relationships of jumbo squid, Dosidicus gigas. Buccal masses, beaks and stomach contents of large and medium maturing-sized ...
Stable isotopes identify age- and sex-specific dietary partitioning and foraging habitat segregation in southern giant petrels breeding in Antarctica and southern Patagonia
(Springer, 2012-03)
We examined the isotopic signatures (δ 13C, δ 15N) of adult body feathers from southern giant petrels Macronectes giganteus collected at two breeding colonies in Antarctica (Potter Peninsula and Cape Geddes) and one in ...
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, ...
