Magnetic non-destructive evaluation of ruptures of tensile armor in oil risers
(IOP PUBLISHING LTDBRISTOL, 2012)
Risers are flexible multilayered pipes formed by an inner flexible metal structure surrounded by polymer layers and spiral wound steel ligaments, also known as armor wires. Since these risers are used to link subsea pipelines ...
Expression profile of components of the beta-catenin destruction complex in oral dysplasia and oral cancer
(Medicina Oral, 2021)
Background: Oral cancer represents the sixth most common cancer in the world and is associated with 40-50%
survival at 5 years. Within oral malignancies, oral squamous cell carcinoma (OSCC) is commonly preceded by
potentially ...
A comparison of stereo-videos and visual census methods for assessing subtropical rocky reef fish assemblage
(2022-03-01)
Visual census conducted by divers has remained the most common method for obtaining quantitative data on reef fish assemblages since it was first applied in the 1950s. More recently, stereo-video systems are increasingly ...
High-throughput non-destructive nuclear magnetic resonance method to measure intramuscular fat content in beef
(SPRINGER HEIDELBERG, 2009)
High intake of saturated fat from meats has been associated with cardiovascular disease, cancer, diabetes, and others diseases. In this paper, we are introducing a simple, high-throughput, and non-destructive low-resolution ...
Electromechanical impedance (EMI) technique as alternative to monitor workpiece surface damages after the grinding operation
(2018-10-01)
Electromechanical impedance (EMI) technique has been employed in detection of structural failure in civil and mechanical structures because of its non-destructive property and easy implementation of small and inexpensive ...
Lamb wave inspection using piezoelectric diaphragms: An initial feasibility study
(2021-11-01)
Lamb wave-based inspection has been extensively investigated and reported in the literature as a non-destructive technique in structural health monitoring and other applications. The generation and reception of Lamb waves ...
Automatic microstructural characterization and classification using artificial intelligence techniques on ultrasound signals
(2013-06-15)
Secondary phases such as Laves and carbides are formed during the final solidification stages of nickel based superalloy coatings deposited during the gas tungsten arc welding cold wire process. However, when aged at high ...
Non-invasive quantification of vitamin C, citric acid, and sugar in ‘Valência’ oranges using infrared spectroscopies
(2020-01-01)
Near (NIR) and mid (MIR) infrared spectroscopies have been studied as potential methods for non-destructive analyses of the fresh fruits quality. In this study, vitamin C, citric acid, total and reducing sugar content in ...
A simple and non-destructive model for individual leaf area estimation in citrus
(Cambridge University Press, 2010-09-01)
Introduction. Leaf area is often related to plant growth, development, physiology and yield. Many non-destructive models have been proposed for leaf area estimation of several plant genotypes, demonstrating that leaf length, ...
ANALYSIS OF THE NATURAL VIBRATION FREQUENCY TEST METHOD TO OBTAIN THE MODULUS OF ELASTICITY OF WOOD STRUCTURAL COMPONENTS
(UNIV FEDERAL VICOSAVICOSA, 2012)
There are several techniques to characterize the elastic modulus of wood and those currently using the natural frequencies of vibration stand out as they are non-destructive techniques, producing results that can be repeated ...
