In this work the rheological behavior of manioc starch (S) industrially modified and its blends with a xyloglucan (XG) in the presence of tetraborate (T) ions at pH 12 was described. At rotational measurements the viscosity values showed a good interaction between polysaccharides (20/5 g/l, respectively, to S and XG), which were highly modified by the presence of tetraborate (7 g/l) resulting in better...
This paper deals with the modeling of electric markets whenever certain imperfections pollute the supplied electrical energy. These imperfections are described in terms of a lack in power quality, and must be quantitatively introduced in the model as an additional economic factor which influences the consumption of electrical energy and its market price. In the model of a commodity market, where electrical...
In this paper it is proposed a simple, although useful model, intended for electricity markets, which enlightens the analysis of regulatory procedures and their consequences over value creation. Today it is widely recognized that, in regard to public services, the aim of regulation should be to maximize the social wealth added (EWA). This wealth includes consumers surplus (ECA), tributes paid to government...
This paper intends to investigate and suggest a new methodology for the location of small power plants that takes into account the triple bottom line (TBL) concept. In other words the location of small power plants should be evaluated considering not only the economic aspects but also the social and environmental ones. This means choosing the area and evaluating the best technology for the equipment...
