Air core notch-coil magnet with variable geometry for fast-field-cycling NMR
(Academic Press Inc Elsevier Science, 2015-10)
In this manuscript we present details on the optimization, construction and performance of a wide-bore (71 mm) α-helical-cut notch-coil magnet with variable geometry for fast-field-cycling NMR. In addition to the usual ...
Air core notch-coil magnet with variable geometry for fast-field-cycling NMR
(2015)
In this manuscript we present details on the optimization, construction and performance of a wide-bore (71 mm) a-helical-cut notch-coil magnet with variable geometry for fast-field-cycling NMR. In addition to the usual ...
The Spb method used to estimate crack extension for coiled tubings fracture toughness tests
(Pergamon-Elsevier Science Ltd, 2017-06)
Coiled tubings are widely used in oil and gas industries. Fracture toughness test of coiled tubing is a challenge. Non-standard specimen has to be used due to its geometrical difficulties, ie small thickness and diameter. ...
Comparative study of helical-cut notch–coil magnets for fast-field-cycling nuclear magnetic resonance
(National Research Council Canada-NRC Research Press, 2014-04)
In this manuscript we describe an -helical-cut notch–coil magnet system designed for fast switching of the magneticfield. An attempt was made to determine the extent to which such a magnet configuration can be efficiently ...
Load-separation method, Spb, used to estimate crack extension for J-R curves, modified for geometric variations in blunt-notched remaining ligament
(American Society Testing Materials, 2017-07)
The Spb method estimates stable crack growth in fracture mechanics precracked specimens test. It compares the load ratio between a precracked specimen that exhibits stable crack growth and a blunt-notched specimen with ...
Characterization of hNek6 Interactome Reveals an Important Role for Its Short N-Terminal Domain and Colocalization with Proteins at the Centrosome
(Amer Chemical SocWashingtonEUA, 2010)
A fast field-cycling MRI relaxometer for physical contrasts design and pre-clinical studies in small animals
(Academic Press Inc Elsevier Science, 2020-03-01)
We present a fast field-cycling NMR relaxometer with added magnetic resonance imaging capabilities. The instrument operates at a maximum proton Larmor frequency of 5 MHz for a sample volume of 35 mL. The magnetic field ...
The male postabdomen of the "ancestral" archostematan beetle Tetraphalerus bruchi Heller, 1913 (Ommatidae) and its phylogenetic significance
(Elsevier, 2011-03)
External and internal features of the male postabdomen of Tetraphalerus bruchi were examined with a broad spectrum of morphological techniques and are described in detail. The conditions found in males of Tetraphalerus are ...
Método de estimación de la profundidad y el ancho de defectos superficiales en placas de aluminio utilizando un sistema de corrientes de remolino con una sonda asimétrica GMR-bobina.
(Panzo López Oswaldo, 2017-09-26)
En este trabajo se utiliza una sonda asimétrica que usa un sensor de magnetorresistencia gigante (GMR) y una bobina plana de excitación para detectar defectos superficiales en placas de aluminio. La bobina de excitación ...
