1. INFLUENCE OF EXPOSURE TIME TO OPERATING TEMPERATURE ON SHEAR STRENGTH OF WOOD USED IN ROOF STRUCTURES
ABSTRACT Wood is one of the main materials used in the constructing of covering structures (roofs) because of its versatility. Under this situation, due to solar radiation incidence, the temperature can exceed 60 °C and, such as other environmental conditions, influence the mechanical properties of the wood in use. The aim of this research was to study the

2. Life cycle analysis of HCNG light-duty vehicle demonstration project
ABSTRACT The demonstration is an effective initiative to bridge the gap between a premature technology and its large-scale commercialization. A systematic method of LCA was used to perform the well-to-wheel analysis of a CNG light-duty truck operated with 0%, 15%, and 30% blends of hydrogen with compressed natural gas fuel under the system boundary of “per

4. Projeto, construção e análise de desempenho de um forno solar alternativo tipo caixa a baixo custo
Apresenta-se um forno solar alternativo construído a partir da sucata de um fogão convencional a gás, que funciona segundo os princípios do efeito estufa e da concentração. O forno do fogão convencional é o recinto de cozimento onde o absorvedor (panela) do forno solar fica localizado, sendo recoberto por uma lâmina de vidro para a geração do efei

7. Caracterização e avaliação do subproduto da industria de gelatina soluvel
The objective of this study was to evaluate the chemical composition of the solid by-product. of soluble gelatin manufacture, as well as to investigate the possibility of utilizing such residue as a proteinaceous ingredient in animal feedstuff. When fresh the residue had about 90% moisture. After drying either in an electric oven or in a solar distill at 70
