1. Análise da influência da malha de pontos em índices de avaliação de desempenho da luz natural
Resumo O desempenho da iluminação natural de ambientes pode ser avaliado por meio de várias ferramentas, a maioria baseada na iluminância. Mesmo com os avanços nas últimas décadas, principalmente os computacionais, a definição dos pontos da malha é deixada, em geral, para escolha do simulador. Este artigo tem como objetivo analisar a influência da

2. Edible Giblets and Bone Mineral Characteristics of Two Slow-Growing Chicken Genotypes Reared in an Organic System
ABSTRACT This study was conducted to compare edible giblets weight, tibial bone mineral density (BMD), and bone mineral content (BMC) of two slow-growing broiler genotypes (Hubbard S757; S757 and Hubbard Grey Barred JA; GB-JA) reared with outdoor access, and to determine the relationship between these variables. Day-old chicks (straight-run) of the genotypes

3. Uso de dispositivo de control solar en aulas: impacto en la simulación dinámica de la iluminación natural
The use of daylighting in educational spaces contributes from different perspectives such as energy, health and comfort. However it requires careful planning during design. The aim of this study is to determine the impact of solar control system in two classrooms (north-south orientation and east-west orientation), typical of regional educational buildings,

4. 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

5. EMISSÃO DE GASES DE EFEITO ESTUFA EM SISTEMAS DE MANEJO EM SOLO DO PLANALTO MÉDIO DO RIO GRANDE DO SUL / SHORT-TERM GREENHOUSE GASES EMISSIONS IN SOIL MANAGEMENT SYSTEMS IN OXISOL OF SOUTHERN BRAZIL
Agriculture is directly linked to atmospheric concentration of greenhouse gases (GHG) through basic processes that occur in the soil-plant system. Agricultural soils can act as a source or sink of GHG depending on the management practices adopted. The objective of this research was to evaluate the GHG flux in different soil management systems. This project w

6. Refrigeração evaporativa por aspersão em telhas de fibrocimento: estudo teórico e experimental
This research focuses the evaporative cooling by water aspersion on wavy cement fiber tiles in the city of São Carlos, SP, seeking to use it to reduce the buildings heat gains. A theoretical model was developed, based on classic equations of fluids mechanic, applied to iterative calculations of heat flows on the tile superior surface, considered as control

7. New daylight redirecting devices: evaluation of their performance under real sky condition / Sistemas inovadores de iluminação natural : estudo de seu desempenho sob condições de ceu real em Campinas, SP
The importance of this research relies on the quantitative evaluation of different daylighting devices, available in the international market, by means of acquiring the iIIuminance through models. This work was accomplished with objective of verifying the application of these systems, restricted to lateral iIIumination in national territory, if they would br

8. Biologia reprodutiva e hibridação em especies sintopicas de Ludwigia (Onagraceae) no sudeste do Brasil
The family Onagraceae Juss. is considered a natural family and particularly interesting to study breeding systems because its moderate size and relatively abundant morphological, systematic, molecular and chemical information. Ludwigia L. is a distinct genus in the family, the only member of the tribe Jussiaeeae, comprises more than 80 species distributed ma

9. Fluorescence Properties of Guard Cell Chloroplasts: EVIDENCE FOR LINEAR ELECTRON TRANSPORT AND LIGHT-HARVESTING PIGMENTS OF PHOTOSYSTEMS I AND II 1
The presence of chloroplasts in guard cells from leaf epidermis, coleoptile, flowers, and albino portions of variegated leaves was established by incident fluorescence microscopy, thus confirming the notion that guard cell chloroplasts are remarkably conserved. Room temperature emission spectra from a few chloroplasts in a single guard cell of Vicia faba sho
