User-producer interaction in the Brazilian oil industry: The relationship between petrobras and its suppliers of wet Christmas tree

The objective of this work is to analyze the importance of the user-producer interaction for the innovative process of the Brazilian oil industry from the 2000s. To do so, we selected two of the three providers installed in Brazil that produce the set of valves used in the oil wellhead to control its production, set which is called wet Christmas tree (WCT), the Norway's Aker Solutions and the American FMC Technologies. The results of this analysis indicate not only the development of the oil industry in Brazil is marked by a strategy of cooperative innovation, but they also reveal the importance of geographical proximity and direct cooperation, especially between the centers of engineering and research and development of companies. Furthermore, these partnerships are not limited to the adaptation of products to new needs, but they also include the development of new systems. © Universidad Alberto Hurtado, Facultad de Economía y Negocios.

Application of bauxite waste from amazon region in the heavy clay industry

In this work, a method was developed for the application of red mud, an alkaline leaching waste, from a bauxite processing plant located in northern Brazil (Amazon region) as starting material for heavy clay products. Samples were prepared by pressing blends of red mud and clay, which were then fired at temperatures from 900 ºC to 1190 ºC. Characterization was carried out by chemical analysis, differential thermal analysis (DTA) and X-ray diffraction (XRD), and the following ceramic properties were evaluated: water absorption, linear shrinkage and flexural strength. In order to evaluate the Na⁺ stability in the dense ceramic, leaching tests were also carried out on the specimens after sintering process. Results indicated that samples with 50 and 70 wt% of red mud are proper for being used in the production of ceramic bodies, due to its excellent properties, mainly high mechanical resistance and low water absorption, showing thus, an option to minimizing the environmental impacts caused by the aluminum industry.

Thermodynamic and economic analysis of hydrogen production integration in the Brazilian sugar and alcohol industry

One of the biggest challenges today is to develop clean fuels, which do not emit pollutant and with viable implementation. One of the options currently under study is the hydrogen production process. In this context, this work aims to study the technical and economical aspects of the incorporation process of hydrogen producing by ethanol steam reforming in the sugar cane industry and MCFC (molten carbonate fuel cell) application on it to generate electric power. Therefore, it has been proposed a modification in the traditional process of sugar cane industry, in order to incorporate hydrogen production, besides the traditional products (sugar, ethylic, hydrated and anhydric alcohol). For this purpose, a detailed theoretical study of the ethanol production process, describing the considerations to incorporate the hydrogen production will be performed. After that, there will be a thermodynamic study for analysing the innovation of this production chain, as well as a study of economic engineering to allocate the costs of products of the new process, optimising it and considering the thermoeconomics as being as an analysis tool. This proposal aims to improve Brazil's position in the ranking of international biofuels, corroborating the nation to be a power in the hydrogen era. (C) 2013 Elsevier Ltd. All rights reserved.

Trade Liberalization, Corn Prices and a Rural Community in Guatemala

Trade liberalization policies in Guatemala have impacted agricultural production. This thesis focuses on how trade liberalization has happened, what have been the impacts at a national level and describes how a community has adapted to the implementation of these policies. The implementation of trade was influenced by several, international and national institutions. Among the international institutions are the World Bank, the World Trade Organization and the United States Agency for International Development. At the national level the institutions that have partaken in shaping the trade policies are the military and the owners of capital and labor. The implementation of trade policies at a national level has affected national corn prices, population level diets and to some extent reduced poverty levels. At a local level trade liberalization policies have impacted land holdings, increased intensification of agriculture, including agrochemical, machinery and crop plantations per year, and consumption rates of corn have been affected. Maximization of the benefits and minimization of the detrimental effects can happen with the implementation of policies that promote food security, improve access to health and education, and prevent environmental and human health consequences from the intensification of agriculture and at the same time continue with the production of non-traditional agricultural products.
