Possibilities of reusing sugar cane straw ash in the production of alternative binders
Sugar cane production is increasing in Brazil due the demand in manufacturing sugar and alcohol. During production process, several wastes are generated, such as sugar cane straw. After a burning process of this waste ...
An alternative approach to solve convergence problems in the backpropagation algorithm
The multilayer perceptron network has become one of the most used in the solution of a wide variety of problems. The training process is based on the supervised method where the inputs are presented to the neural network ...
Leaching of Ni and Cu from mine wastes (tailings and slags) using acid solutions and A. ferrooxidans
The objective of this work is to evaluate the acidic and biological leaching of tailings containing Ni/Cu from a flotation and smelting plant. Acidithiobacillus ferrooxidans, strain LR, was used for bioleaching at pH 1.8 ...

Reducing the electrical resistance of films of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate).
(Associação Brasileira de PolímerosPorto de Galinhas, 2014-10-12)
Semi-conductive polymer thin films were prepared from solutions of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT/PSS) by spin coating. A commercial solution of PEDOT/PSS was submitted to different modification ...
Fundamental principles of the Toyota Way and the Theory of Constraints: Comparative analysis and synthesis
Several researchers have attempted to understand the essence of the principles that support Toyota Way and Theory of Constraints management philosophies, because they recognise such principles as central to explain their ...
