1. PERFORMANCE AND WELFARE OF FINISHING PIGS SUBJECTED TO CLIMATECONTROLLED ENVIRONMENTS AND SUPPLEMENTARY LIGHTING
ABSTRACT An adequate thermal environment in pig farming facilities is essential to ensure productivity and animal welfare. The objective of this study was to evaluate the behavior and performance of finishing pigs, subjected to climate-controlled environments and supplementary lighting. Twenty-seven pigs (3/4 Duroc, 1/4 Pietrain) were kept in pens with no cl

2. Evolving granular systems = : Sistemas granulares evolutivos / Sistemas granulares evolutivos
In recent years there has been increasing interest in computational modeling approaches to deal with real-world data streams. Methods and algorithms have been proposed to uncover meaningful knowledge from very large (often unbounded) data sets in principle with no apparent value. This thesis introduces a framework for evolving granular modeling of uncertain

3. Iluminação natural em setores de produção de edifícios industriais : estudos de caso na região metropolitana de Campinas / Daylighting in manufacturing sectors of industrial buildings : case studies in the metropolitan region of Campinas
Although daylighting is a renewable resource, clean and costless, support to energy efficiency of a built environment and promoter of wellness state and health, it is not yet used in an efficient way in industrial building design, probably because architects and its clients ignore its principles, resources and possibilities. On the other hand, one notes an i

4. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

5. Aplicação do corante da casca da berinjela em células solares fotossensibilizadas. / Application of dye from the peel of eggplant in photosensitizer in solar cells.
Despite the efficiency of conventional solar cells reach about 20%, the cost of producing electricity using photovoltaic panels about 42 cents per kWh is still much higher than the cost of power generated by hydroelectric, 8 cents per kWh. Given the high cost of producing solar panels, woke up the interest in solar cells using dyes fotoexcitáveis known as G

6. Percepção da iluminação no espaço da arquitetura : preferências humanas em ambientes de trabalho / Perception of lighting in architectural space : preferences in work environments.
As preferências humanas de iluminação nos ambientes internos estão relacionadas inicialmente à satisfação de conforto luminoso a partir de exigências não somente visuais, mas fisiológicas de saúde, conforme os objetivos do projeto e atividades. Este trabalho aborda a percepção da iluminação natural e artificial complementar diurna, em ambiente

7. Desempenho lumínico em edificação escolar com estratégias sustentáveis e bioclimáticas : um estudo de caso
New manners on how to inhabit the planet are sought due to the increasing society development, in order to preserve it for the future generation. The seeking for low-energy consumption alternatives is one of the key issues the man can intervene in order to preserve earth´s natural resources. The usage of natural light is extremely valuable in edifications w

8. Tratamento de efluente tÃxtil utilizando o processo foto-fenton / Treatment of textile effluent using photo-fenton process
The aim of this work was to study the performance of the photo-Fenton process using both the artificial UV and solar sources on the textile effluent treatments. Preliminary photo-Fenton experiments for mineralization and degradation of organic and inorganic pollutants as well as of synthetic dyes were carried out in order to assess the best experimental cond

10. Light as an indicator of ecological succession in brazilwood (Caesalpinia echinata Lam.)
The ecophysiological behavior of brazilwood (Caesalpinia echinata Lam.) plants was evaluated as affected by light quantity and quality. Nine-month-old plants were cultivated under 0%, 50%, and 80% artificial shading, and natural shading imposed by a closed canopy for a period of 392 days. At the end of that period growth parameters were measured, including r

11. Meetings and misunderstandings of natural light : a study in hospital wards. / Encontros e desencontros da iluminação natural : um estudo em espaços de internação hospitalar.
A luz natural apresenta inúmeras vantagens entre elas a variabilidade, servindo como fonte de estímulo fisiológico e emocional para o ser humano. Em ambientes de internação hospitalar a permanência prolongada e a vulnerabilidade física solicitam condições ambientais não só eficientes como confortáveis e capazes de proporcionar respostas positivas
