1. Uso de sistemas modulares vegetados para promoção da saúde urbana e atenuação do estresse térmico
RESUMO O processo de urbanização possui efeitos significativos no microclima local, resultando no surgimento das ilhas de calor e comprometimento das condições térmicas no interior de habitações. A aplicação de sistemas modulares vegetados em telhados ou coberturas surge como alternativa à melhoria das condições térmicas no interior de habitaç�

2. Efeito de dois sistemas de resfriamento sobre os hormônios tireoidianos e as variáveis termofisiológicas de matrizes suínas em lactação
RESUMO Avaliaram-se os efeitos do sistema de resfriamento evaporativo com pressão negativa (SRE) e aspersão de água sobre o telhado (AAT), as variáveis termofisiológicas, os hormônios tireoidianos e a relação neutrófilo:linfócito (N:L) em porcas. Utilizaram-se 61 fêmeas em lactação, que foram divididas nos dois ambientes térmicos, sendo 30 em S

3. Uma análise comparativa do desempenho de quatro sistemas de umidificação do ar em condições de seca no centro-oeste brasileiro
Resumo Quatro sistemas de umidificação do ar foram examinados e seus desempenhos comparados sob condições de seca do centro-oeste brasileiro. Esses sistemas são umidificador elétrico, bacia com água, toalha úmida e um sistema artesanal feito com telhas cerâmicas especialmente para este trabalho. A avaliação foi realizada entre julho e outubro de 2

4. Analysis of the Operation of Photovoltaic Systems Installed at Federal University of Technology - Paraná in Curitiba
ABSTRACT The Federal University of Technology - Paraná (UTFPR), Campus Curitiba, has a Grid-Connected Photovoltaic System (GCPVS) of 2.1 kWp in the Green Office (GO), which has been in operation since December 2011, and until September 2017 generated little more than 13.64 MWh and a GCPVS of 10.2 kWp, in operation since February 2016. The photovoltaic panel

5. Numerical analysis of truss systems with stiffened flattened end-bars
Abstract Circular hollow sections are usually used in long-span roof truss systems. One of the typology for connecting elements in such structures involves the flattening of bar ends. This article presents the numerical analysis of a plane truss composed of circular hollow sections, in which diagonal bars have flattened ends. In this sense, a new flattening

6. 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

7. BASIC UNIT COST SIMULATION FROM FREE-STALL DESIGN TO DAIRY CATTLE CONFINEMENT USING DIFFERENT CONSTRUCTION TECHNIQUES
ABSTRACT The ascendancy of milk production in Brazil is due to mainly to the adoption of confinement systems, however, construction quality of these systems impact on milk production. This study aimed to simulate the Basic Unit Cost (BUC m-2), referring to a free-stall design with capacity for 80 animals and different construction techniques, with a database

8. Estudio experimental sobre el comportamiento térmico de un nuevo tipo de techo-estanque para el enfriamiento pasivo en clima húmedo
In this paper, a new type of metal roof-pond based on indirect evaporative cooling and including confined thermal mass is experimentally evaluated. Five passive cooling systems have been studied with this experimental device. Their characteristic temperatures are analyzed in order to determine the cooling potential in each case and the influence of the therm

9. Evaluation of reflective painting of the roof and artificial ventilation on performance and carcass yield of broilers
This study was developed with the objective of evaluating reflective paint on covering and artificial ventilation on performance of broilers (males and females). A randomized design with a 2 × 2 × 2 factorial arrangement of treatments was used, as follows: 2 external management systems (coverage with and without reflective paint), 2 internal management sys

10. Roof modular system in wood and particle board (OSB) to rural construction
Wood is a material of great applicability in construction, with advantageous properties to form various structural systems, such as walls and roof. Most of the roof structural systems follow models that have remained unchanged for a long time. A roof modular system in distinguished materials is proposed: reforested wood (Pine), oriented strand board (OSB) an

11. A pré-fabricação de dois sistemas de cobertura com madeira de florestas plantadas. Estudos de casos: os assentamentos rurais Pirituba II e Sepé Tiaraju / The two prefabricated roofing systems with soft-wood from reforestations. Case studies: the rural settlements Pirituba II and Sepé Tiaraju
Grande parte das moradias brasileiras apresenta coberturas inadequadas, conforme indicação de pesquisa sobre o deficit habitacional. A carpintaria dessas coberturas necessita de mão de obra qualificada e materiais de custos elevados, porém, na maioria dos casos ainda hoje utiliza processo construtivo artesanal. O objetivo deste trabalho é identificar qu

12. Comparative study of steel purlins in conventional beams, in planar trusses and multi-planar trusses / Estudo comparativo entre terças de aço, convencionais em vigas, em treliças planas e em treliças multiplanares
Steel roof systems are widely used in buildings that require large free internal spaces and small execution times, such as commercial and industrial warehouses and storage and distribution centers. The purlins have a considerable contribution in the roof system total weight composition. In this work was developed a study on the different types of purlins for
