1. Multistage Phase Decomposition Behavior and Kinetics for Zr65Ni30Pd5 Ternary Amorphous Alloy
We have examined heating-induced phase decomposition and its kinetics for Zr65Ni30Pd5 amorphous alloy in an argon atmosphere. The amorphous phase decomposes through three stages in the order of amorphous → icosahedral quasicrystal (I-Q) + amorphous → approximant cubic Zr2(Ni,Pd) → tetragonal Zr2Ni + tetragonal Zr2Pd phases. The approximant crystalline

2. Migração por extrapolação de ondas em três dimensões / Migration by wave extrapolation in three dimensions
In three dimensions, migration methods based on solving the one-way wave equation, besides facing problems to handle evanescent waves and to image steep dip reflectors, are still computationally expensive. For the problems of imaging steep dip reflectors and treat evanescent waves, in this dissertation, we use the complex Padé approximation. Because solving

3. Atitudes linguisticas : a variante retroflexa em foco
The aim of the present study is to identify and analyze some students? language attitudes toward their native dialect. The topic of this study is the /r/ retroflex pronunciation. The students are in graduating program and they are native from São José do Rio Preto (SP) who have been living in Campinas (SP) since they began studying at State University of C

4. Processos de polimerização e transição de colapso em polímeros ramificados. / Polymerization processes and collapse transition of branched polymers.
The phase diagram and the tricritical point of a collapsing lattice animal are studied through an extended series expansion of the isothermal compressibility KT on a square lattice. As a function of the variables x (fugacity) and y = e1/T (T is the reduced temperature), this series KT is investigated using the partial differential approximants technique. The
