Aspects de conception et de construction d'un bateau d'assaut en composites ArchiMer
Kader, A; Yaakob, O; Samian, Y.
To help spur the defence industry in Malaysia, the Government is encouraging indigenous research and development effort. This paper describes the development of a prototype fibreglass assault boat at the Universiti Teknologi Malaysia. The boat, designed for riverine and coastal water operations was modelled on aluminium boats currently used by the Malaysian Armed Forces. The completed boat has been evaluated and some minor modifications will be made on the final prototype to be built soon.

Construção e utilização do "carro prensa" para aproveitamento dos restos de cultura em pequenas propriedades do Nordeste. Infoteca-e
POSSIDIO, E. L. de.
A escassez de pastagens na época da estiagem é um dos mais graves problemas para os pequenos e médios criadores da região semi-árida do Nordeste do Brasil. O aproveitamento dos restos de cultura é uma das alternativas viáveis para a solução do problema, desde que os criadores disponham de meios para fazê-lo na época mais crítica e da forma mais adequada.

Development of a Bush Mango (Irvingia Gabonensis) Nutcracker-6 CIGR Journal
Alonge, A.F..
This research work involves the design and fabrication of Irvingia nut cracking machines. It operates using impact technique which involves collision between the seednut and stationary wall. The procedures employed the design stage, fabrication and testing. The machine components are: impact drum, shaft, impeller (rotor), electric motor, driver and driven pulley and hopper. The cracking chamber consists of the impeller and impact drum. The seednuts were pre-treated before testing by sun-drying to improve its crackability. The machine gave a better performance at the speed of 2600 revolution per minute with average cracking efficiency, percentage kernel breakage and capacity of 88%, 17.5% and 916 nuts/hr. The improvement in the design can be achieved by...

EI Scale: an environmental impact assessment scale related to the construction materials used in the reinforced concrete BABT
Morales,Gilson; Jungles,Antonio Edésio; Klein,Sheila Elisa Scheidemantel; Guarda,Juliana.
This study aimed to create EI Scal, an environmental impact assessment scal, related to construction materials used in the reinforced concrete structure production. The main reason for that was based on the need to classify the environmental impact levels through indicators to assess the damage level process. The scale allowed converting information to estimate the environmental impact caused. Indicators were defined trough the requirements and classification criteria of impact aspects considering the eco-design theory. Moreover, the scale allowed classifying the materials and processes environmental impact through four score categories which resulted in a single final impact score. It was concluded that the EI scale could be cheap, accessible, and...

Reductions in turbidity and Escherichia coli density using passive polymer treatment CIGR Journal
Berry, James; Sawyer, Calvin; Privette, Charles; Hayes, John; Bridges, William.
Current research shows sediment basins may act as reservoirs for potentially harmful bacteria, including Escherichia coli (E. coli). E. coli preferentially attach to clay-sized particles and have been found in sediment basin outflows with high turbidity levels containing concentrations exceeding water quality standards recommended by the US Environmental Protection Agency. Since research shows E. coli preferentially attach to the clay fraction within sediment, it was hypothesized that a reduction in turbidity and TSS would create a corresponding reduction in bacterial density.  Construction site sediment basin discharge was simulated to determine whether a sediment tube configuration using anionic polymer application could reduce E. coli densities. Based...
