This work deals with the mechanical performance and the water sorption characteristics of compression molded unsaturated polyester composites reinforced with an all jute fabric and an especially manufactured hybrid jute-glass ...

Thin films of Ti using the deposition technique by hollow cathode, were produced under Al2O3 surface aiming at obtaining ceramic-ceramic indirect brazing. Metallizing surfaces of excellent uniformity were obtained, and it ...

In recent years, mining companies mainly beneficiation of kaolin and granite have been cited by environmentalists as sources of contamination and/ or pollution of the environment due to the huge amount of waste generated ...

The aim in this work is to study the performance of an “air lift” electrochemical reactor, in semipilot scale, which was used in the eletroflotation process applied in the oils and greases separation in oil-water emulsions ...

This work seeks to study the diffusion phenomenon in porous solids with arbitrary geometry, to present the numeric solution of the equation that describes the phenomenon for extrusion solids and to propose a numeric ...

This work presents ananalytical/numerical study of the laminar flow of fluid through straight ducts of arbitrary cross sections,obtaining results for fluiddynamics parameters of interest,such as: Fanning attrition factor, ...

This research was conducted with the objective of analyzing the lipid composition of catole coconut oil (Syagrus oleracea Mart.) with regard to the fatty acid profile, oil identity and possible variations resulting from ...

The use of alternative fuels is gaining prominence worldwide, because beyond petroleum be an exhaustible source of energy, emits large amounts of polluting gases. Proposals have emerged to replace fóssil fuels, among which ...

The objective of this research was to study the effect of techniques of: 1) freezing in temperatures of-20 °C, -196 °C and -170 °C; 2) storage in temperatures of (-20 °C, -30 °C and -170 °C, and 3) of unfreezing method ...

Microorganisms, aside from their industrial importance in obtaining several products by biotechnology, can be used directly as food for humans and animals. In this context, an interest in non-conventional sources of protein ...
