DNA tests probe the genomic ancestry of Brazilians [PDF]

Brazilian Journal of Medical and Biological Research, 2009
We review studies from our laboratories using different molecular tools to characterize the ancestry of Brazilians in reference to their Amerindian, European and African roots. Initially we used uniparental DNA markers to investigate the contribution of distinct Y chromosome and mitochondrial DNA lineages to present-day populations.

A Novel Analytical Solution for the Brazilian Test with Loading Arcs [PDF]

Mathematical Problems in Engineering, 2020
This research study presents a new theoretical model to calculate the indirect tensile strength for the Brazilian disk with loading arcs, based on numerical simulations, two-dimensional elasticity theory, and Griffith failure criterion. The new expression incorporates a no uniform contact pressure distribution determined by the results of the ...

Color Trails Test: a Brazilian normative sample [PDF]

Psicologia: Teoria e Pesquisa, 2010
present study aims to evaluate psychometric data on the population of Brazil using of the Color Trails Test (CTT). The instrument was applied to 1,942 subjects who came from the north (1.4%), northeast (10.4%), midwest (7.7%), southeast (65.9%), and south (13.9%) regions of Brazil. Ages varied from 18 to 86 years (M = 40.03 years; DP = 16.02), with 386

A simple discrete-element-model of Brazilian test [PDF]

The European Physical Journal B, 2016
We present a statistical model which is able to capture some interesting features exhibited in the Brazilian test. The model is based on breakable elements which break when the force experienced by the elements exceed their own load capacity. In this model when an element breaks, the capacity of the neighboring elements are decreased by a certain ...

Proposal for a Brazilian centre on alternative test methods

ALTEX, 2009
Several initiatives have recently taken place in Brazil in order to foster the creation of centers dedicated to alternatives to animal testing. In 2008, Vanessa Sá-Rocha organized a meeting with Brazilian regulatory authorities and the major stakeholders in the field of testing to foster discussions on the process of funding, development, and ...
