Rheology of oleo gels based on sorbitan and glyceryl mono stearates and "Fobias mas raras yahoo dating" oils for lubricating applications.
Oleo gels based on sorbitan and glyceryl mono stearates and different types of vegetable oils, potentially applicable as biodegradable alternatives to traditional lubricating greases, have been studied.
In particular, the rheological behavior, by means of small-amplitude oscillatory shear SAOS measurements, and some lubrication performance-related properties mechanical stability and tribological response have been evaluated in this work.
SAOS response and mechanical stability of these oleo gels are significantly influenced by the type and concentration of the organogelator and the vegetable oil used in the formulations. The use of low-viscosity oils, such as rapeseed and soybean oils, yields gels with significantly higher values of the linear viscoelastic functions than oleo gels prepared with high-viscosity oils, i. The rheological behavior of SMS-based oleo gels also depends on the cooling rate applied during the gelification process.

Implementation and testing of the use of vegetable oils as fuel diesel generators in the Amazon isolated communities; Implantacao e testes de utilizacao de oleo vegetal como combustivel para diesel geradores em comunidades isoladas da Amazonia.
The project PROVEGAM 'Implantation and test of a unit demonstration of energetic utilization of vegetable oil', tested in operational conditions of field, the functioning of a conventional diesel engine, adapted to operate with palm oil 'in natura' in the community of Vila Soledade, city of Moju, Para State.
The Vila Soledade is an isolated community that has, approximately, inhabitants and it's located at one hundred kilometers from the city hall by car and more 30 minutes by boat. The electric energy of this community was previously generated, by a conventional diesel engine, obsolete and very expensive to the community, because the fuel price and the transport of the diesel oil from the city to the community.
Because of the viscosity of the palm oil and its combustion point, it was necessary to heat the vegetable oil before its injection into the engine. The operation begins and finishes with diesel oil, in order to heat the palm oil and to clean possible residues
Fobias mas raras yahoo dating in the interior of the engine. The use of the palm oil justifies itself for being produced in the region, which means that it doesn't have to be imported. Currently, the generating group is working in the community during 5 hours per day with palm oil, and 1 hour per day with diesel oil and it already has more than hours of testing.
The results of this project, so far, have confirmed the conceived premises, and this electric model of generating energy is already recommended to be implemented in other communities in the Amazon region. Impacts of fuel oil substitution by natural gas in a pipeline network scheduling; Impactos da substituicao do oleo combustivel por gas natural na programacao de uma rede de dutos.
Souza Filho, Erito M. In recent decades, due to the advancement and computational methods for solving optimization problems, the number of articles addressing the scheduling of products has grown. The mathematical models developed have proved useful to schedule from a single pipeline with multiple products to complex networks of multiple pipelines. Moreover, the planning of these activities is of even greater importance when considering the existence of new environmental requirements to be applied to production and marketing of petroleum products.
An example of this paradigm shift is the reduction in fuel oil consumption due to increased share of natural gas in the Brazilian energy matrix. In this context, this paper proposes a mathematical model to obtain feasible solutions for problems of scheduling a network of pipelines considering replacing all or part of the demand for fuel oil to natural gas.
We tested the model on three real instances of a multi commodity network consists of 4 terminals, 4 refineries and 8 unidirectional pipelines, considering a planning horizon of one week.
