1. The use of light-emitting diodes (LED) in commercial layer production
Artificial lighting is one of the most powerful management tools available to commercial layer producers. Artificial light allows anticipating or delaying the beginning of lay, improving egg production, and optimizing feed efficiency. This study aimed at comparing the performance of commercial layers submitted to lighting using different LED colors or conven

2. Redes neurais com topologias otimizadas aplicadas na modelagem de dados geotécnicos e pluviométricos para predição de deslizamentos de solo
The problems related to landslides caused by rain on slopes have been a reality in several cities of Brazil and parts of the world. The government and research institutions have sought, in partnership, solutions to minimize the damage caused by such accidents, from studies of correlation between rainfall and landslide occurrences enabling the development of

3. SÃntese de grafeno pelo mÃtodo CVD. / Graphene Synthesis by CVD Method
The advancement and improvement of synthesis techniques and handling of materials are fundamental to understand their properties and possible forms of production and use. However, in the case of nanomaterials, problems such as structural defects, high cost and difficulty of achieving production on a large scale have yet to be solved. Inserted in this panoram

4. Embryonic stem-like cells derived from in vitro produced bovine blastocysts
The aim of this work was to study the derivation of bovine embryonic stem-like (ES-like) cells from the inner cell mass (ICM) of in vitro produced blastocysts. The ICMs were mechanically isolated and six out of seventeen (35%) ICMs could attach to a monolayer of murine embryonic fibroblasts (MEF). Ten days after, primary outgrowths were mechanically dissecte

5. Estudo do comportamento dos parâmetros de frequências das camadas Es na região equatorial durante períodos perturbados / Studies of the frequency parameters associated with es-layer in the equatorial ionosphere during disturbed periods
Esta dissertação de mestrado apresenta os resultados dos estudos do comportamento dos parâmetros de frequência da camada Es da ionosfera equatorial durante os períodos perturbados do ciclo solar 23 (1998-2006). Foi conduzida uma investigação, nos dias anteriores, durante e posteriores a tempestades magnéticas, sobre a evolução temporal dos parâmet

6. COMUNIHC-ES: FERRAMENTA DE APOIO À COMUNICAÇÃO ENTRE PROFISSIONAIS DE IHC E ENGENHEIROS DE SOFTWARE / COMUNIHC-ES: AN HCI TOOL TO SUPPORT THE COMMUNICATION BETWEEN HCI PROFESSIONALS AND SOFTWARE ENGINEERS
Developing interactive systems involves professionals from many areas of expertise, including HCI (Human-Computer Interaction) and Software Engineering (SE), each one with specific focus and goals. HCI focuses, generally, on understanding the users` characteristics, needs and objectives, their work environment and the tasks they need or want to perform using

7. O pico pré-inversão na deriva vertical de plasma e a camada E esporádica / The vertical plasma drift prereversal peak and the sporadic E layer
A análise dos dados ionosféricos para a estaçãoao brasileira Fortaleza mostrou que os processos de desenvolvimento do pico pré-inversão na deriva vertical do plasma, ao entardecer, estãoo conectados à formação da camada E esporádica (Abdu et al., 2003). No presente trabalho foram analisados dados de três estações ionosféricas no Brasil. Os par

10. Análise das características dos relâmpagos na região sudeste do Brasil / Lightning characteristics in southeastern Brazil
The first climatological studies of cloud-to-ground (CG) lightning flashes characteristics in Brazil were published at the middle of 90. However, at that time, the lightning detection network used to be composed by only a few sensors, which restricted the analyses to some specific regions. In the beginning of this decade, new studies were published using lig

11. Effect of epithelial debridement on human cornea proteoglycans
Corneal transparency is attributed to the regular spacing and diameter of collagen fibrils, and proteoglycans may play a role in fibrillogenesis and matrix assembly. Corneal scar tissue is opaque and this opacity is explained by decreased ultrastructural order that may be related to proteoglycan composition. Thus, the objectives of the present study were to

12. Medidas do perfil da permissividade eletrica em interfaces solido-liquido, usando microscopia de força atomica
When immersed in water, several surfaces are electrically charged. Therefore, repulsive and attractive forces between the tip and the sample are detected during image generation by atomic force microscopy in aqueous medium. In the last decades repulsive forces have been attributed to electrostatic interactions, while attractive forces have been ascribed to v
