Atmospheric corrosion tests in Brazilian Legal Amazon – field and laboratory tests

Materials and Corrosion, 2000
This paper presents the first results concerning tests carried out to evaluate the atmospheric corrosion in Brazilian Legal Amazon, as part of the SIVAM - Amazon Surveillance System. The aim of the present work is to determine and select materials as well as anti-rust paints, which will be employed to protect metallic structures of radar towers ...

High Allelic Heterogeneity Between Afro-Brazilians and Euro-Brazilians Impacts Cystic Fibrosis Genetic Testing

Genetic Testing, 2003
Cystic fibrosis (CF) is an autosomal recessive disease caused by at least 1,000 different mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR). To determine the frequency of 70 common worldwide CFTR mutations in 155 Euro-Brazilian CF patients and in 38 Afro-Brazilian CF patients, we used direct PCR amplification of DNA from ...

Cracked Brazilian Tests of Lamellar Tial

2007
A disc specimen containing a center-crack and subjected to a compressive load has also been used frequently for mixed mode fracture tests in brittle materials since first introduced [1]. This is often called the cracked Brazilian disc specimen. Brazilian disc specimen containing a center-crack and subjected to a compressive load has also been used ...

Fracture testing of Brazilian disk sandwich specimens

International Journal of Fracture, 2002
The reliability of a joint subjected to mechanical and thermal loads during processing and service constitutes a major technical problem. Joints contain flaws. The observed strength of a joint depends upon the location and size of the flaws, as well as the crack path through the joint.

MPT.BR: A Brazilian Maturity Model for Testing

2012 12th International Conference on Quality Software, 2012
The discipline of software testing is increasingly drawing industry's attention to itself due to the demand for quality products and the high level of competition in the market. This scenario can be supported by a maturity model that continuously improves the discipline of testing when applied to the software development lifecycle.

Rock failure under the confined Brazilian test

Journal of Geophysical Research, 1966
The Brazilian, or indirect tensile, test, in which a disk is loaded in a diametral plane by forces applied at opposite ends of a diameter, is extended by jacketing the specimen and applying an additional confining pressure. In this way failure may be studied over a range of conditions in which the least principal stress varies from tensile to ...

Brazilian Tensile Strength Testing of Compacted Clay

Geotechnical Testing Journal, 2017
Laboratory tests were conducted to examine the applicability of the Brazilian tensile strength (BTS) method (ASTM D3967-16) for measuring tensile strength of compacted clay. A correction function obtained from tests using disk-shaped kaolinite specimens compacted over wide range of void ratio was developed to account for variability in void ratio among

Microbiology proficiency testing of Brazilian accredited laboratories

Accreditation and Quality Assurance, 2015
Proficiency testing (PT) schemes are an important tool to evaluate the performance of the laboratories. In microbiological testing, one of the most frequent areas for testing in Brazilian accredited laboratories, there are specific challenges related to the variability in measurement results (organisms, methods, matrices and others) all the more as ...
