1. Bebidas de Kefir com e sem inulina em versões integral e desnatada : elaboração e caracterização química, física, microbiológica e sensorial
The beverage Kefir is a result of fermentation of milk by lactic acid bacteria, aceticacid bacteria and yeasts contained in Kefir grains or in lyophilized starter culture. Besides bacteria and yeasts, the beverage contains minerals, vitamins B and essential amino acids, important for the maintenance of the vital functions of the organism. The beverage consum

2. Oscilação de neutrinos no formalismo de pacotes de onda / Neutrino oscillation in the wave packet approach
Generally, we study neutrino oscillation phenomenon using the plane wave formalism, which successfully treats the solar neutrino case, the reactor and accelerator cases. However, a more complete description of neutrino oscillation must consider a wave packet approach. This work analyses both formalisms: the plane wave and the wave packet in vacuum and matter

3. Spin flavor oscillation of neutrinos in rotating gravitational fields and their effects on pulsar kicks
The origin of high velocities of pulsars is studied by considering the spin-flip conversion of neutrinos propagating in a gravitational field of a protoneutron star. For a rotating gravitational source (such as pulsars) with angular velocity , one finds that the spin connections (entering in the Dirac equation written in curved space time) induce an addition

4. Introdução a fenomenologia da oscilação de neutrinos, no vacuo e na materia / Introduction to neutrino oscillation s fenomenology, in vacuum and matter
The subject of this work is to produce a didactic text that can be used by physics students as a basis when incoming on the neutrinos phenomenology area. We introduce the neutrinos mixing model in vacuum, based on the concept of state superposition. We show that this hypothesis leads to avor oscillation phenomenon, the one is proposed to be a solution to the

6. Descoerencia na propagação de neutrinos
In this work we discuss the Neutrino temporal evolution adding the decoherence phenomenon to flavor oscillation. We describe very carefully how the phenomenological decoherence should be added to the evolution and what are the consequences and possibilities that this choice bring to us. Imposing decoherence we found three new dynamics to Neutrino system that

7. Neutrino mass, mixing and oscillations
Present data from various neutrino experiments are strongly suggesting the existence of neutrino mass and flavor mixing. We review the present status of neutrino oscillation search and various neutrino anomalies and their possible interpretations in terms of oscillation induced by neutrino mass and flavor mixing.
