1. 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

2. Investigation of the Roof Presplitting and Rock Mass Filling Approach on Controlling Large Deformations and Coal Bumps in Deep High-Stress Roadways
Abstract Roadway deformation and coal bumps are major challenges for underground engineering. Taking the Lu'an mining district in Shanxi Province as an example, the failure mechanism of deep high-stress roadway was studied. Numerical simulations and the similar material test were performed to investigate the effect of the roof presplitting and rock mass fill

3. Determining the Contribution of Ventilation and Insulation of Broiler Breeding Houses in Production Performance Using Analytic Hierarchy Process (AHP)
ABSTRACT This study was conducted using Analytic Hierarchy Process (AHP) in order to rank broiler breeding farms in Zanjan province, Iran, regarding buildings, installations, and equipment to determine their effects on production factors. Data on 108 farms were collected using designed forms. This data was analyzed based on the effectiveness of each paramete

4. Avaliação de diferentes materiais de cobertura para construção do telhado de aviários móveis
This research aimed to: 1) was to test different materials of cover the roof of aviaries furniture on thermal comfort indices for birds; and 2) was to evaluate the surface temperature and cloacal broiler chickens raised in aviaries furniture, with different covers for the roof. To test different roofing materials for the roof aviaries were built three mobile

5. Estudo de influência de cobertura plástica na remoção de água de lodos de estações de tratamento de água em leitos de drenagem
A maior parte das Estações de Tratamento de Água (ETAs) para abastecimento existente no Brasil se utiliza de captação de águas superficiais e sistema de tratamento de ciclo completo convencional. Neste tratamento são retidos/gerados resíduos que variam principalmente segundo o tipo e quantidade de produto químico adicionado e as características do

6. Processamento de aço inoxidável dúplex por extrusão em canal angular
A duplex stainless steel with austeniticferritic structure, type S32205/S31803 was submitted to equal channel angular pressing, whose is based on very severe plastic deformation, at relatively low temperature, with no change in the dimensions along transversal section of the material. The processed material was heat treated at 1000 and 1200C during 7.5, 15,

7. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol

8. Análise Paramétrica de Ligações com Placa de Extremidade em Estruturas de Aço Submetidas a Momento Fletor e Força Axial / Parametrical Analysis of Structural Steel Endplate Joints Subjected to Bending Moment and Axial Force.
Traditionally, the steel portal frame design assumes that beam-to-column joints are rigidor pinned. Rigid joints, where no relative rotations occur between the connected members, transfer not only substantial bending moments, but also shear and axial forces. On the other extreme, pinned joints, are characterised by almost free rotation movement between the c
