13. Vazios urbanos e imóveis subutilizados no Centro Histórico tombado da cidade de João Pessoa
This dissertation aims to identify, quantify and characterize the urban voids and underutilized properties present in the area of the Historic Center of João Pessoa - listened by IPHAN. The object of research was delimited from the questioning of the existence of a housing stock capable of reuse in polygonal of rigorous preservation of IPHAN to the Center o

14. Crescimento e propriedades vibracionais de cristais a base de Ãxidos / Growth and Vibrational Properties of Oxide Crystals
In this work we used different experimental techniques to study four different series of inorganic oxide crystals, namely: (i) congruent lithium isotope niobate (C7LN), (ii) rare-earth doped mixed vanadates ((Nd,Yb):YxGd1-x(VO4)); (iii) alkali metal doped and pure calcium barium niobates (CaxBa1-xNb2O6); and (iv) potassium tantalite niobate (KTa1-xNbxO3). Be

15. Caracterização estrutural e eletrônica da zircônia pura e com defeitos e impurezas / Structural and electronic characterization of zirconia, pristine and with impurities
In this investigation we studied the electronic properties and the structural stabilities of zirconia (ZrO2), as well as oxygen vacancy and Ce substitutional impurity. The investigations were carried by computational simulations using ab initio methods, based on the density functional theory and the APW + lo (Aumengted Plane Waves plus local orbitals) method

16. A popularização do centro de São Paulo: um estudo de transformações ocorridas nos últimos 20 anos / Popularization of São Paulo city center: a case study of transformations occurred in the last 20 years
This work seeks to identify transformations occurred in São Paulo city center from the early 90s until today. In the 90s, the city center territory is fraught with social complexities, ideologically publicized as degradation. While on the one hand it is located between São Paulos main employment hubs, it concentrates a large number of vacant properties and

18. Prestes Maia´s Social Networking / Teia de relações da ocupação do edifício Prestes Maia
The building number 911 on Avenida Prestes Maia, in the center of São Paulo city, since 1990 without use, was occupied in 2002 by the homeless movement of the center (MSTC). As from the XX century, several ocupations were realized by social movements fighting for home in empty buildings in the center of the city, as means to pressure public power to put int

19. Study of the influence of structural defects in the properties of carbon nanotube / Estudo da influência de defeitos estruturais nas propriedades de nanotubos de carbono
We have investigated the influence of defects on structural, electronic and mechanical properties of single-walled carbon nanotubes (SWCNT), bundles of nanotubes and multi-walled carbon nanotubes (MWCNT). All our results were obtained with the first principles theory of total energy - Density Functional theory (DFT). We have investigated the structural prope

20. ESTUDO DE PRIMEIROS PRINCíPIOS DE DEFEITOS NATIVOS EM MONÓXIDO DE BERÍLIO / FIRST PRINCIPLES STUDY OF NATIVE DEFECTS IN BERYLLIUM MONOXIDE
The present thesis shows a study of native defects (vacancies and antisites) in Beryllium Monoxide (BeO) by means of first principle calculations within Density Functional Theory (DFT). We made use of Local Density Aproximation (LDA) in order to approach correlation and shift term, and ultrasoft pseudopotentials in order to describe the electron-core interac

21. Mecanismos químicos e mineralógicos de transformação da magnesioferrita de solo derivado de tufito, da região do Alto Paranaíba, MG
Magnetic soils forming on tuffite of the region of Alto Paranaíba, Minas Gerais, Brazil, usually contain iron-rich spinels exceptionally rich in magnesium and titanium. In this work, samples of the magnetically separated portion from the sand fraction of a Brunizém (Chernossolo) and from its mother-rock material were analyzed with synchrotron X-ray diffrac

22. Redistribuição e ativação de dopantes em Si com excesso de vacâncias
A redistribuição e ativação elétrica dos dopantes tipo n (As e Sb) e tipo p (Ga e In) em Si com excesso de vacâncias foram analisadas. As vacâncias foram geradas por implantação iônica de altas doses de oxigênio ou nitrogênio em alta temperatura, de acordo com procedimentos já estudados. Em seguida foram implantados os dopantes com dose de 5x101
