1. Wilting whole crop black oat with glyphosate for ensiling: effects on nutritive, fermentative, and aerobic stability characteristics
ABSTRACT We aimed to evaluate the effects of glyphosate as a chemical desiccant on the nutritional quality, fermentation pattern, and aerobic stability of wilted black oat (Avena strigosa Schreb) silage. Black oat sowing occurred in the first fortnight of May 2013. Desiccant application took place when oat reached milky/dough grain stage (96 days after plant

2. Populações e evolução do bojo e região central da Galáxia / Populations and the evolution of the bulge and central region of the Galaxy
O presente trabalho propõe uma abordagem abrangente para descrever a evolução da região central da Via Láctea, compreendendo-se aí o bojo, a barra e as interfaces dos mesmos com o limite interno do disco e com a região central do halo. Pretende-se investigar as propriedades químicas e cinemáticas destas estruturas, que são interconectadas, com o ob

3. Formação e evolução de galáxias: populações estelares na Via Láctea, galáxias elípticas e propriedades de galáxias em grupos / Galaxy Formation and Evolution: From the Milky Way to Galaxies in Groups
Understanding the way galaxies form and evolve throughout the cosmic time remains one of the greatest challenges of modern cosmology. Several processes are known to play a role in the formation of galaxies, such as feedback from supernovae and active galactic nuclei, chemical and dynamical evolution and environmental effects. This thesis encompasses these pr

4. Search for very metal-poor stars based on carbon over-abundance / Busca por estrelas muito pobres em metais baseada no enriquecimento em carbono
The main goal of this work is to show that is possible to search for metal-poor stars based on the premise that a large fraction of these will be carbon-rich. This hypothesis had not yet been verified because many of the so-called CEMP (Carbon Enhanced Metal-Poor) stars were neglected in previous studies due to the design of the search for metal-poor stars w

5. Modelo da galáxia utilizando contagens de estrelas no infravermelho / Galaxy model by using infrared star counts
The majority of first quantitative models for the structure of Galaxy used the star counts method to explore the most important galactic structure parameters as a whole. Some of the most important models owe to Bahcall \& Soneira (1980), the Besançon group (Robin \& Crezé (1986)), Wainscoat et al. (1992), Ortiz \& Lépine (1993), among others.

6. Ambient concerns: the case of the exporting agro-industries of milky derivatives in Minas Gerais / PreocupaÃÃes ambientais: o caso das agroindÃstrias exportadoras de derivados lÃcteos em Minas Gerais.
It is clearly that the technological globalization, innovations and growth of the industrial sector bring some benefits to a reasonable parcel of the society, such as: comfort and quality of life. However it is also responsible for ambient catastrophes, social and economic problem that contribute for an unsustainable development. This ambient crisis in alert

7. Black holes in the Milky Way Galaxy
Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4–16 times the mass of the sun, whereas the latter are “supermassive black holes” with millions to billions of s

11. Surface Photometry of Celestial Sources from a Space Vehicle: Introduction and Observational Procedures*
Diffuse celestial sources of relatively low surface brightness such as the Milky Way, zodiacal light, and gegenschein (or contre lumière) can be studied most reliably from above the earth's atmosphere with equipment flown in artificial satellites. We review the techniques used and some of the difficulties encountered in day-time observations from satellites

12. Neutrinos
Neutrinos represent a new “window” to the Universe, spanning a large range of energy. We discuss the science of neutrino astrophysics and focus on two energy regimes. At “lower” energies (≈1 MeV), studies of neutrinos born inside the sun, or produced in interactions of cosmic rays with the atmosphere, have allowed the first incontrovertible evidenc
