RF probe recovery time reduction with a novel active ringing suppression circuit
(Academic Press Inc Elsevier Science, 2005-11)
A simple Q-damper device for active probe recovery time reduction is introduced along with a straightforward technique for the circuit's component value optimization. The device is inductively coupled to a probe through a ...
Avaliação hemodinâmica em oclusões vasculares do membro posterior de ratos
(Universidade Federal de São Paulo, 2022-11-17)
O restabelecimento do fluxo sanguíneo arterial macrovascular em pacientes portadores da doença arterial obstrutiva crônica (DAOP) melhora as taxas de cicatrização de feridas, dor em repouso e diminui a necessidade de ...
ANP impairs the dose-dependent stimulatory effect of ANG II or AVP on H+-ATPase subcellular vesicle trafficking
(Scientific ResearchDelaware, 2013-08)
The effect of angiotensin II (ANG II) or arginine vasopressin (AVP) alone or plus atrial natriuretic peptide (ANP) on H+-ATPase subcellular vesicle trafficking was investigated in MDCK cells following intracellular pH (pHi) ...
Interstitial oxygen related defects and nanovoids in Au implanted a-SiO2 glass depth profiled by positron annihilation spectroscopy
(IOP Publishing, 2015-11)
Samples of amorphous silica were implanted with Au ions at an energy of 190 keV and fluences of 1×1014 ions cm−2and 5×1014 ions cm−2 at room temperature. The damage produced by ion implantation and its evolution with the ...
Detecção de O2 através de provas fosforescentes com elevada resolução temporal
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2018-10-11)
This work presents a new gaseous oxygen sensing system based on time resolved phosphorimetry. The instrument is designed based on a violet LED (low power) and a high sensitivity photomultiplier module. The arrangement has ...
Lixiviação convencional e lixiviação assistida por ultrassom de elementos terras raras a partir de fosfogesso
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2023-02-28)
Rare earth elements (REE) are a group of elements with very similar physical and chemical
properties. They include the 15 elements of the lanthanide series (La–Lu), Y, and Sc. The
need for these elements in different ...
Effects of Hydrogen Treatment and Air Annealing on Ultrafast Charge Carrier Dynamics in ZnO Nanowires Under in Situ Photoelectrochemical Conditions
(Amer Chemical SocWashingtonEUA, 2012)
Diseño de un Equipo de Recuperación de Líquidos de Gas Natural Empleando CFD
(2015)
En el proceso convencional para el tratamiento de gas natural se emplean tres etapas: endulzamiento, deshidratación y control de punto de rocío (HDP: Hydrocarbon Dew Point). Este proceso permite llevar el gas natural a ...
