1. Magneto-Elastic Analysis of an Annular FGM Plate Based on Classical Plate Theory Using GDQ Method
Abstract Using GDQ method, the radial and circumferential stresses in an annular FGM plate with a uniform thickness under a transverse axisymmetric load is investigated. It is assumed that a uniform radial magnetic field acts on the top surface of the plate. The modulus of elasticity E and the magnetic permeability coefficient μ of the plate along its thick

2. Magnetotransporte em poços-quânticos de AlGaAs/GaAs com diferentes formas de potencial / Magnetotransport in AlGzAs/GzAs quantum wells with different potential shapes
In this thesis we present studies of magnetotransport in double quantum wells (DQWs) in low magnetic fields and under application of an external electric field (gate potential). Measurements of magnetoresistance have been carried out in both linear and non-linear regime. We report on the observation of magneto-intersubband (MIS) oscillations for the first ti

4. ConfiguraÃÃo, anisotropia e defeitos em uma rede de vÃrtices na presenÃa de nanoarmadilhas
Since Abrikosov s work in 1957, it. has been clear the vortex lattice existence and stability in specific magnetic fields and temperature values of type ll super- conductors. On external currents and Thermic fluctuations, vortices move through the superconductor salable resulting thermal dissipation. But it is salvage to most. actual technologic applications

5. Estudos de relaxação magnetica em supercondutores do tipo - II
We present in this work a study of magnetic relaxation in superconducting Y1Ba2CU3O7-d samples. We have used a single crystal grown in zirconia crucible, with Tc ~ 90 K and D T ~ 2 K; and a directionally solidified MTG sample with 17 % of Y211, Tc ~ 91 K and .D T ~ 2 K for H = 10 Oe. We discuss in a simplified manner the most relevant aspects of the magnetic

6. Quasi-elastic behavior of solutions of viral capsid and RNA at very low shearing stresses.
By the application of shearing stresses on the order of 10(-3) dyne cm-2 (10(-2) muN cm-2), via the magnetic viscodensimeter, extremely high relative viscosities (greater than 500) were observed when turnip yellow mosaic virus was degraded in alkali into its capsid and RNA. The solutions, however, possessed a watery consistency at this stage and exhibited a
