Heat transfer and magnetovortical antiresonance of a ferrofluid with a rotating magnetic field
(2013-06-01)
We investigate theoretically a ferrofluid in the presence of a rotating magnetic field using a phenomenological approach based on a equation of motion for the magnetization. We verify that the heating rates of the system ...
Magnetic Resonance Imaging in Knee Osteoarthritis Research: Semiquantitative and Compositional Assessment
(W B SAUNDERS CO-ELSEVIER INC, 2011)
Semiquantitative assessment of the knee by expert magnetic resonance imaging readers is a powerful research tool for understanding the natural history of osteoarthritis (OA). Several reliable semiquantitative scoring systems ...
Contribution of magnetic resonance in acute spinal cord trauma - case report
(Univ Federal Rural Pernambuco, 2011-12-01)
Acute spinal cord trauma is a common injury that occurs frequently in small animals. In order to acertain a prognosis of the lesion generated in the spinal cord, it is necessary to perform a complete neurological and ...
Electric and magnetic properties of polymer electrolyte/carbon black composites
(1998-12-01)
Measurements of 1H Nuclear Magnetic Resonance (NMR) relaxation times, Electron Paramagnetic Resonance (EPR) and AC Impedance Spectroscopy (IS) are reported for composites based on PEO8:LiClO4 and carbon black (CB), prepared ...
Cardiovascular assessment of patients with Ullrich-Turner's Syndrome on Doppler echocardiography and magnetic resonance imaging
(Sociedade Brasileira de Cardiologia (SBC), 2002-01-01)
OBJECTIVE: To assess the cardiovascular features of Ullrich-Turner's syndrome using echocardiography and magnetic resonance imaging, and to correlate them with the phenotype and karyotype of the patients. The diagnostic ...
Communiols E-H: New polyketide metabolites from the coprophilous fungus Podospora communis
(2005-03-01)
Communiols E-H (1-4), four new polyketide-derived natural products containing furanocyclopentane, furanocyclopentene, cyclopentene, or γ-lactone moieties, have been isolated from two geographically distinct isolates of the ...
NMR-SSC magnetic field profiler applied to magnetic field shimming
(Institute of Electrical and Electronics Engineers, 2013-02)
A new methodology aimed to control the spatial dependence of a magnetic field within a volume of interest is described. The designed hardware uses Nuclear Magnetic Resonance (NMR) to sense the magnetic field. A modified ...
