Capillary imbibition in mortars with natural pozzolan, limestone powder and slag evaluated through neutron radiography, electrical conductivity, and gravimetric analysis
(Pergamon-Elsevier Science Ltd, 2019-04)
The description of the capillary imbibition phenomenon can help to understand and enhance the durability of cementitious materials containing supplementary cementitious materials (SCMs). We studied the effect of slag, ...
Hard X-ray dosimetry of a plasma focus suitable for industrial radiography
(Pergamon-Elsevier Science Ltd, 2018-04)
Dosimetric measurements of the hard X-ray emission by a small-chamber 4.7 kJ Mather-type plasma focus device capable of producing neat radiographs of metallic objects, were carried out with a set of thermoluminescent ...
Small Plasma Focus Studied as a Source of Hard X-ray
(Institute of Electrical and Electronics Engineers, 2001-06)
An experimental study on hard X-ray pulses emitted by a small plasma focus is performed, regarding its application to biological radiographs in fast dynamic situations. It is found that the radiation intensity in a single ...
Determinación de bajas concentraciones de hidrógeno en aleaciones de circonio utilizando radiografía de neutrones como técnica no destructivaDetermination of low concentrations of hydrogen in zirconium alloys using neutron radiography as a non-destructive technique
(Universidade Federal do Rio de Janeiro, 2018-07)
Las aleaciones base circonio (Zr) se utilizan en la fabricación de las vainas de combustible y en componentes estructurales de los reactores de potencia por su baja absorción neutrónica. Estas aleaciones son susceptibles ...
Synthesis and evaluation of thermal neutron attenuation properties of lithium orthosilicate for its application as a beam shaping material on BNCT facilities
(Pergamon-Elsevier Science Ltd, 2020-03)
Thermal neutron attenuation capacity of Li4SiO4 was evaluated to assess its potential capabilities as a beam shaping material for boron neutron capture therapy (BNCT) facilities. Samples of Li4SiO4 were prepared by two ...
Imaging of boron distribution in steel with neutron radiography and tomography
(Springer, 2020-06)
B distribution in steel was investigated using neutron imaging techniques, on a millimetric scale with a spatial resolution below 100 μm. Steel structural components joined using the transient liquid-phase bonding (TLPB) ...
Chest x-ray automated triage: A semiologic approach designed for clinical implementation, exploiting different types of labels through a combination of four Deep Learning architectures
(Elsevier Ireland, 2021-07)
Background and objectives: The multiple chest x-ray datasets released in the last years have ground-truth labels intended for different computer vision tasks, suggesting that performance in automated chest x-ray interpretation ...
Radiografía de la ilusión: Reactivación productiva del algodón y mercado de trabajo en una economía extra-pampeana de ArgentinaRadiography of illusion: Reactivation productive of cotton and work market in an extra-pampas of Argentina’s economy
(Universidad de Jaén. Departamento de Territorio y Patrimonio Histórico. Área de Antropología Social, 2018-12)
A pesar de que la combinación “terrateniente-ganadero”- “Agricultor familiar capitalizado” (tipo farmer) domina buena parte de las regiones del país, existen zonas de campesinos y/o campesinos indígenas que le otorgan ...
Radiografía de los gabinetes ministeriales en Brasil y Perú (2016-2018). Un análisis comparativoRadiography of ministerial cabinets in Brazil and Peru (2016-2018). A comparative analysis
(Universidad Dr. Rafael Belloso Chacín, 2019-05-08)
A partir del triunfo de fuerzas políticas con perfil y orientación derechista en varios países de América Latina, las ciencias sociales retomaron un debate histórico acerca de los grupos de poder y el modo en que estos ...
Radiologic Evaluation of the Llullaillaco Mummies
(American Roentgen Ray Society, 2003-12)
OBJECTIVE. Our purpose was to determine the imaging findings in three 500-year-old frozen mummies of sacrificial Inca children. MATERIALS AND METHODS. CT, conventional radiography, and dental radiography of Inca mummies ...
