Indigenous braiding as a reference in surface design - Bok av José Paulo Medeiros Da Silva - Häftad

Indigenous braiding as a reference in surface design - Bok av José Paulo Medeiros Da Silva - Häftad

The object of this work was to study indigenous braiding as a theoretical and formal reference for creating surface designs. When working on the proposal to develop surface designs with an ethnic reference, a counterpoint is sought to the current complacency of the Brazilian furniture industry, where the standard of aesthetics and, above all, of \good form\ is simply imported from the European market. Therefore, a design that incorporates a part of Brazilian culture - indigenous braiding - and..

Numerical Study of Mixed Convection in a Cavity - Bok av Lyes Bordja - Häftad

Numerical Study of Mixed Convection in a Cavity - Bok av Lyes Bordja - Häftad

Convection is a way of transporting energy by means of potential gradients and fluid movement. Convection is the most important mechanism for transferring energy between a solid surface and a liquid or gas at a different temperature. Energy transfer by convection from a surface whose temperature is higher than that of the surrounding fluid takes place in several stages. The essential characteristics of heat transfer by convection are the transport of energy by molecular movement, known as 'diffusion',..

Elasticities of short and long term demand for ethanol in Brazil - Bok av Leonardo Cardoso - Häftad

Elasticities of short and long term demand for ethanol in Brazil - Bok av Leonardo Cardoso - Häftad

The future scarcity of fossil fuels is not an opinion shared by the whole of academia, but the need for cleaner energy sources is a consensus. Based on this, first generation ethanol from Brazilian sugarcane becomes an excellent energy alternative because it presents better environmental indicators at a competitive cost in some Brazilian states. However, studies on the demand for ethanol worldwide are scarce and this scarcity, surprisingly, is repeated in Brazil. In recent literature, for example,..

Biodeterioration caused by insects in furniture of the Museo de La Plata. - Bok av Maria Fernanda Rossi Batiz - Häftad

In Argentina, the main insects causing biodeterioration in furniture of heritage value are beetles (Ptinidae, Coleoptera). The most frequent species in wood in service are Anobium punctatum and Xyletinus brasiliensis. The damage corresponds to internal galleries and semicircular holes on the surface, which cause weakening of the support. Cockroaches (Blattodea) and spiders (Araneae) produce fecal stains, spider webs contribute to the accumulation of dirt and the remains of the aforementioned fauna..
