1. Estudo de materiais magnéticos através de técnicas fototérmicas : efeito magnetocalórico e filmes finos / Study of magnetic materials using photothermal techniques : magnetocaloric effect and thin films
The magnetocaloric effect (MCE) has been widely studied because of its possible application in magnetic refrigeration. The search for suitable materials has intensified over the last decade, with a demand not only for the preparation of new materials but also for their complete characterization. The aim of this work is to apply the photothermal techniques to

2. Peltier efect in quasiperiodic structures semiconductors / Efeito Peltier em estruturas semicondutoras quasiperiódicas
There is nowadays a growing demand for located cooling and stabilization in optical and electronic devices, haul of portable systems of cooling that they allow a larger independence in several activities. The modules of thermoelectrical cooling are bombs of heat that use efect Peltier, that consists of the production of a temperature gradient when an electri

3. LOCAL ISOTROPY ASSUMPTION AND THE UNIVERSALITY OF THE KOLMOGOROV CONSTANT / A HIPÓTESE DE TURBULÊNCIA LOCALMENTE ISOTRÓPICA E A UNIVERSALIDADE DA CONSTANTE DE KOLMOGOROV
According to the Kolmogorov s fully developed turbulence theory established in 1941, there is an equilibrium range in which phenomenological quantities associated to the turbulence flow are described by laws of universal character. The main objection to this theory was given by Landau, who critized the universality of these laws arguing that an universal sta

4. Determinação de parâmetros produtivos e qualitativos de Cynodon spp. em função de variáveis climáticas / Predicting yield and qualitative characteristics of Cynodon spp. in response to climatic variables
As pastagens são o principal recurso alimentar para pecuária brasileira, sendo fundamentais na viabilização dos sistemas produtivos. Fatores climáticos como temperatura e fotoperíodo têm grande importância no crescimento das plantas forrageiras, influenciando o acúmulo de forragem a distribuição estacional da produção e do valor nutritivo, fator
