1. Diagnosis and validation by computational fluid dynamics of poultry house with negative pressure ventilation
RESUMO A ventilação à pressão negativa em aviários vem sendo utilizada para viabilizar a correção de seus microclimas internos, sendo que pesquisas apontam para a distribuição heterogênea do ar ao longo dos galpões e inadequação das variáveis ambientais às faixas recomendadas para o conforto térmico de aves adultas, especialmente nas horas ma

2. Study of natural ventilation in a Gothic multi-tunnel greenhouse designed to produce rose (Rosa spp.) in the high-Andean tropic
Resumo Nas regiões tropicais, a produção de plantas ornamentais é desenvolvida exclusivamente em estufas plásticas ventiladas de forma natural, o que significa que em algumas ocasiões microclimas inadequados são gerados com altas temperaturas e umidade que limitam o desenvolvimento produtivo das plantas. O objetivo deste trabalho foi estudar os fluxos

3. Mass Balance Applied to Brazilian Conventional Broiler Houses during One Production Cycle
ABSTRACT Brazil plays an important role in global poultry production as it is the world's largest chicken exporter and the third largest broiler producer. Despite the development achieved by the Brazilian broiler industry as a result of the integrated production system, many obstacles still need to be overcome, in particular, housing environment. In this reg

4. Thermal gradients of container and mean surface temperature of broiler chicks transported on different shipments
ABSTRACT This study aimed to evaluate the thermal gradients between the container environment and the interior of chick boxes and mean surface temperature of broiler chicks during transportation on different shipments. The research was conducted in the state of São Paulo, Brazil, with the accompaniment of nine shipments with different density boxes, using a

5. Capacidade de deterioração de cepas de Eucalyptus spp. por fungos xilófagos / Capacity of deterioration of stumps of Eucalyptus spp. by xylophagous fungi
On the reform of the forest stand, after the cutting of trees, the remaining strains of Eucalyptus spp. must be removed. The natural degradation of stumps of eucalypts after clear cutting is slow. The mechanical destock raises the cost of production, involves machinery traffic on the ground favoring soil compaction and hindering the growth and distribution o

6. Adequação bioclimática para os espaços urbanos abertos do centro de Fortaleza, CE
This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The p

7. Configuração urbana e conforto térmico externo: uma avaliação em espaços urbanos na cidade de Maceió-AL. / Urban configuration and external thermal confort: an assessment in urban areas in the city of Maceió-AL.
A adequação climática dos ambientes externos urbanos é um fator importante para a obtenção de conforto térmico humano, particularmente em cidades tropicais, onde boa parte das atividades urbanas pode ser desenvolvida nos espaços externos. Diante disso, o presente trabalho busca contribuir para estudos em conforto térmico em espaços urbanos tropicai

8. Ecology of Haemagogus sp. and Sabethes sp. (Diptera: Culicidae) in relation to the microclimates of the Caxiuanã National Forest, Pará, Brazil
This study was conducted in a meteorological tower located in the Caxiuanã Forest (municipality of Melgaço, Pará, Brazil) with the aim of assessing the vertical stratification of species of Haemagogus and Sabethes, potential vectors of the yellow fever virus. To investigate the role of microclimates in mosquito stratification, bimonthly collections were c

9. Estudo de um sistema de análise de preferências climáticas para animais convencionais de laboratório por tecnologia de ventilação microambiental e avaliações biológicas. I. Avaliação da eficiência de um protótipo, para o estudo de parâmetros ambientais, resultados parciais verificados em ratos (Rattus norvegicus) / A climatic chamber employing Intracage Ventilation System to evaluated house condition of laboraroty animals and to biological assays in thermoregulation studies. Partial evaluation in rats (Rattus norvegicus)
Projects concerned with laboratory animals facilities usually adopt narrow range of ventilation and climatization variables to assure the define ambient. Such projects are concerned to the animal room (macro-environmental ambient) and this technology have a limitated operation to reach the micro-environmental (animal cages) ambients. The development of the i

10. O impacto da vegetação nos microclimas urbanos / The Impact of vegetation in urban microclimates
The main purpose of this research is the effects of vegetation in urban microclimate conditions, under the premise that the presence of vegetation influences the microclimate and its surroundings. Considering different forms of green space distribution and using native species, it could quantify the intensity and spatial distribution for the microclimate eff

11. A influência da vegetação sobre o clima urbano de Palmas-TO / The influence of vegetation on urban climate of Palmas-TO
This study addresses the issue of urban climate. It is based on the assumption that vegetation may act to improve the microclimate conditions of cities, by reducing the temperature of the air, which is very important in warm climates. Aims to investigate the influence of vegetation on urban climate in Palmas, capital of the province of Tocantins. It was base

12. Urban climate Ponta Grossa-PR: an approach to climate dynamics in subtropical Brazilian city average / Clima urbano em Ponta Grossa - PR: uma abordagem da dinâmica climática em cidade média subtropical brasileira
The human being has led to changes in climate through the transformation of nature, whether for its occupation of space, is to develop its activities. To the extent that the man is concentrated in certain áreas, pressure on the natural conditions increases. The city is one of the best examples of the concentration of people and activities in one place and a
