This paper proposes the multi-objective optimization of the design of natural gas transmission networks to support the decision of regulatory authorities. The problem formulation involves two objective functions: the minimization of the transportation fare and the maximization of the transported gas volume. These design parameters of the pipeline project must be previously established by the regulatory agency, considering an attractive return on the investment for the entrepreneurs and the demands of current and future consumers. The solution of this problem without an optimization tool may imply in unfair gas prices or the lack of investors interest. The proposed analysis is focused on growing markets, associated to a continuous increase of the natural gas consumption. Constraints associated to gas flow and compressor stations guarantee the feasibility of the set of design options found. Aiming to illustrate the performance of the proposed approach, the tool was applied to a typical trunkline example. © 2016

This article addresses the design problems associated with pipe networks in cooling water systems. The objective is to determine the lowest cost network that can supply the heat exchangers with cooling water at the flow rates previously established in the thermal design. The solution to the problem provides the diameter for each section of pipe in the network together with the corresponding pump alternative. The objective function and constraints are organized in a matrix formulation where the solution consists of a set of linear programming problems. The basic structure of the optimal design problem also extends to the solution for revamp problems. The comparison of the proposed approach to the traditional solution based on economical velocities indicates that the optimization scheme can make pipe network designs less expensive and more reliable for supplying cooling water. © 2014 Copyright Taylor & Francis Group, LLC.

The aim of this article is to prioritize the factors and alternatives relating to the reference conditions for the biodiesel production chain for the Brazilian Program for Biodiesel Use and Production. Multicriteria mapping of stakeholders' preferences was used to structure 20 interviews with specialists from Brazil representing three key areas (academy, industry, and regulatory bodies). The methodology started with a review of the literature on the sustainability of the biodiesel production chain based on market data, a review of 138 scientific articles indexed in the CAPES "Web of Science" database, which were searched using "biodiesel" and "sustainability" as keywords, and an analysis of the sustainability criteria used in related legislation and voluntary sustainability initiatives. Next, the reference conditions for the sustainability of the biodiesel production chain were structured, starting with the links and then the factors and their respective impacts and prioritizations given by the stakeholders. The results obtained from all the respondents indicate that the six most critical parameters are: improving the productive capacity of the land, non deforestation, production inputs, land access, engine problems, and land use for food production, which jointly accounted for 55.5% of the total priorities. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 1262-1270, 2013 Copyright © 2012 American Institute of Chemical Engineers.

This work reports fundamental experimental-theoretical research related to heat transfer enhancement in laminar channel flow with nanofluids, which are essentially modifications of the base fluid with the dispersion of metal oxide nanoparticles. The nanofluids were synthesized by a two-step approach, using a dispersant and an ultrasound probe or a ball mill for alumina nanoparticles dispersion within the aqueous media. The theoretical work involves the proposition of an extension of the thermally developing flow model that accounts for the temperature variation of all the thermophysical properties, including viscosity and the consequent variation of the velocity profiles along the thermal entry region. The simulation was performed by making use of mixed symbolic-numerical computation on the Mathematica 7.0 platform and a hybrid numerical-analytical methodology (generalized integral transform technique, GITT) in accurately handling the governing partial differential equations for the heat and fluid flow problem formulation with temperature dependency in the thermophysical properties. Experimental work was also undertaken based on a thermohydraulic circuit built for this purpose, and sample results are presented to verify the proposed model. The aim is to confirm that both the constant properties and temperature-dependent properties models, besides available correlations previously established for ordinary fluids, provide adequate prediction of the heat transfer enhancement observed in laminar forced convection with such nanofluids and within the experimented Reynolds number range. © 2013 Copyright Taylor and Francis Group, LLC.

This paper aims to study discontinuous deep frying of potatoes, milanesas (breaded bovine Semimembranosus muscle) and churros (flour, water, milk, lemon and salt) in soybean oil, sunflower oil and partially hydrogenated fats, monitored by conventional and unconventional methods. With the exception of partially hydrogenated fat after 80.5 h of deep-frying churros, all the oils exceeded 25% of total polar compounds (TPC) and the content of polymeric and dimerized triacylglycerols were higher than 10%, prevailing thermal alterations. For none of the samples the percentage of free fatty acids exceeded 2% of oleic acid. The losses of tocopherols during frying reached 76.0%. Little significant alterations occurred in the fatty acids composition, iodine index calculated, saponification index and formation of trans isomers after frying. The rapid tests used to determine TPC, malondialdehyde and alkenals have proved to be viable alternatives to monitor the quality of frying oils. © 2011 Elsevier Ltd.

The United Nations Framework on Climate Change (UNFCCC) took effect as a treaty in 1994 to promote international cooperation in the fight against global warming. Currently, nearly 190 countries are signatories of the UNFCCC, which has had successive additions as the Kyoto Protocol (1997). In 1995, the Climate Technology Initiative was established within the UNFCCC to encourage international cooperation in the accelerated development and diffusion of environmentally Sound Technologies - EST. Such technologies are also capable of protection provided by patents, and this kind of protection is a valuable tool for the industrial production inventions to become a worthwhile investment, contributing to economic development. Many patent applications claim advantages relative to efficiency, waste reduction, or even the costs of operation/ manufacturing. However, the difficulty of accurately distinguishing the EST's technologies among others, which are those that only claim environmental benefits, compared to those who actually have a higher potential to promote a more positive impact on the environment directed. This study aims to report some performance initiatives in relations between technologies, focusing on the so-called "GREEN", and the effects of climate change. Some initiatives have already been started in countries such as Australia Canada, United States United Kingdom Spain Japan, South Korea and Israel. These nations are constituted in the form of their industrial property offices, as entities that have implemented regulations regarding the patentability of requests for green technologies or EST's such requests are known as "green patents" applications. In this context, it is highlighted that the definition of "green patents" differs from country to country and this leads to greater uncertainty in this designation, with the codes of the International Patent Classification (IPC) should be prioritized. This study observed that, in the case of South Korea, green patents are technologies classified in accordance with the interests of the Government, or, according to designations of environmental laws. Moreover, it still shows that South Korea Australia, United States Japan, Israel already have programs to promote accelerated examination of "green patents" applications with different criteria.

The aim of this paper was to evaluate the effectiveness of the quick tests Viscofrit, Testo 265 and Fri-check in the monitoring of used frying oil for discarding, as a substitute for the measurement of total polar compounds (TPC), indicating the advantages and disadvantages of each test. Fifty-nine frying oil samples used to fry different types of food were evaluated using quick tests and the TPC open-column conventional method. The samples presented TPC values from 6.0 ± 1.1% to 39.2 ± 1.0%. Testo 265 was correlated to the conventional method by the equation: y = 0.89. x + 4.0 (r = 0.90), with a 5% level of significance. A correlation factor of 0.9 (α = 0.05) was essential for these results, since water in the food increases the TPC values. Viscofrit provided results consistent with the open-column method for 78.8% of the samples, with 9.3% of false positive results. Testo 265 and Viscofrit showed good results for the substitution of the TPC conventional method, respecting their limitations. Viscofrit is not recommended for high melting point samples. © 2012 Elsevier Ltd.

Introduction: New tools and approaches are necessary to facilitate public policy planning and foster the management of innovation in countries' public health systems. To this end, an understanding of the integrated way in which the various actors who produce scientific knowledge and inventions in technological areas of interest operate, where they are located and how they relate to one another is of great relevance. Tuberculosis has been chosen as a model for the present study as it is a current challenge for Brazilian research and innovation. Methodology: Publications about tuberculosis written by Brazilian authors were accessed from international databases, analyzed, processed with text searching tools and networks of coauthors were constructed and visualized. Patent applications about tuberculosis in Brazil were retrieved from the Brazilian National Institute of Industrial Property (INPI) and the European Patent Office databases, through the use of International Patent Classification and keywords and then categorized and analyzed. Results/Conclusions: Brazilian authorship of articles about tuberculosis jumped from 1% in 1995 to 5% in 2010. Article production and patent filings of national origin have been concentrated in public universities and research institutions while the participation of private industry in the filing of Brazilian patents has remained limited. The goals of national patenting efforts have still not been reached, as up to the present none of the applications filed have been granted a patent. The analysis of all this data about TB publishing and patents clearly demonstrates the importance of maintaining the continuity of Brazil's production development policies as well as government support for infrastructure projects to be employed in transforming the potential of research. This policy, which already exists for the promotion of new products and processes that, in addition to bringing diverse economic benefits to the country, will also contribute to effective dealing with public health problems affecting Brazil and the World. © 2012 Vasconcellos, Morel.
