14. Coproduce or Codevelop Military Aircraft? Analysis of Models Applicable to USAN
The creation of the Union of South American Nations (USAN) aroused expectations about joint development and production of military aircraft in South America. However, political divergences, technological asymmetries and budgetary problems made projects canceled. Faced with the impasse, this article approaches features of two military aircraft development exp

15. Divergences Between New Patterns of Global Trade and Brazil/Mercosur
Although integration has been a part of South American discourse for decades, the level at which it is actually promoted remains far from that which is observed in dynamic production and trading centers. Given transformations in global trade, the phenomenon of global value chains is, in fact, very regionalized. We ask whether the trading pattern of Mercosur

16. Revestimentos de alta camada obtidos com a modificação de resinas epóxi novolaca pela reação com organo-siloxano e catálise ácida
Epoxy resins are an important class of thermostable polymers, widely used in structural applications or as adhesives. However, the low fracture resistance is their main weakness in many applications. Due to this fact, this study aims to modify a polymer matrix based on a novolac epoxy resin with an organo siloxane (AMS). The final properties of cured epoxys

17. Effects of Path Dependence on Capabilities in Captive Global Value Chains
Global Value Chains (GVC) and their participants are dynamic. Events can provoke distinct strategic responses from different firms, even when they are part of a GVC. We investigated how both organizational and supply-chain path dependence can influence the capabilities that a firm needs to achieve a higher value-added position in a GVC. We have integrated th

18. Synthesis Optimization of MCM-41 for CO2 Adsorption Using Simplex-centroid Design
There is a growing concern on the relationship between anthropogenic carbon dioxide and climate changes. A promising approach is the adsorption technology using mesoporous MCM-41 materials that can be easily synthesized to depict structures adequate to the flow of gas. The aim of this study was to improve the synthesis of MCM-41 using cationic surfactant mix

19. Development and characterization of hybrid materials based on biodegradable PLA matrix, microcrystalline cellulose and organophilic silica
The goal of this work was to investigate the production and properties of hybrid materials based on poly(lactic acid) (PLA), employing microcrystalline cellulose (MCC) and organophilic silica (R972) as fillers. The composites were obtained by solution casting to form films. Each nanoparticle was incorporated at 3 wt. %, relative to the polymer matrix. In thi

21. A definição do sortimento-profundidade nos supermercados brasileiros: influência nas vendas e critérios utilizados / The definition of in-depth assortment supermarkets Brazilians: influence on sales and criteria used
Even before the heating of the Brazilian economy in recent years, the past decade was marked by a growing number of products launched in the mass consumer market, the vast majority not having survived a year of existence. At the same time the Brazilian consumers are presented with greater purchasing power, increased consumer expectations and increased access

23. The influence of the industrial processing on the degradation of poly(hidroxybutyrate) - PHB
PHB was characterized after different industrial processes by Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), Melt Flow Index (MFI), Complex Dielectric Relaxation (CDR) and Size Exclusion Chromatography (SEC). Some properties of PHB were investigated before and after processing, in order to understand how temperature
