The purpose of this article is to highlight examples of railway heritage listed in Brazil and propose a reinterpretation on them from an industrial archaeology approach. For ours, this approach about the railway transport remains allows better understanding of some Brazilian industrialization practices (architectural, technological and social). Even an industrial archaeological point of view about theses listed railroad sites could review aspects of Brazil's railway history. Consequently, we try to demonstrate the potential of this approach, if applied to remains of railway transportation. In the end, we emphasize the importance of recognizing the railway operation functional aspects to a better understanding of the railway system. [ABSTRACT FROM AUTHOR]

This article explores the challenges derived from the discovery of huge oil reserves under the salt layer, called Pre-salt, poses to Brazilian economy and society. These challenges are technological, but also of economic and institutional nature. The article depicts what these challenges are, focusing on the recent developments in the Brazilian oil industry and analyses these evolutions under the light of debate about "curse of natural resources" and Dutch disease. The Brazilian situation reveals great potential advances in the technological and productive level, with a clear perspective that Brazil will become a great oil exporter. However based on evidences from Petrobras and the oil supply industry since the Pre-salt discoveries, alongside with the institutional evolution, the article points out the risks that the country reproduces some of the problems pointed out by international literature over the curse of natural resources.

Brazil (1955-2005): 25 years of catching-up, 25 years of falling behind. The present paper discusses the Brazilian industrial development under a neo-schumpeterian perspective in the period after 1955. The hypothesis is that, in the last 50 years, Brazil spent the first 25 years catching up and, next, the following 25 years falling behind. The 1955-1980 period, by means of international funding, allowed catching up with the paradigm in maturation within the fourth technological revolution. However, in this period, it was determined the main debilitating elements for the country's entrance in the new techno-economical paradigm of the fifth technological revolution which emerged in the middle of the 70s. It is in the strategy to internationalize the economy, granting the mutinational companies the key-sectors of the national economy dynamics during the catching up period, the main element of dependence in the journey that conditions the current performance, responsible for technology subordination and keeps the Brazilian economy with low dynamism.

The mineral industry was one of the pioneers of Brazilian industrialization and presents live one of its better moments with high international demand of mineral commodities, in special the iron ore concentrates. The usual characteristic to all companies are: great installations, large use of chemicals, water, energy and natural resources. One of the challenges of the support is the optimization of the chemical's products of all the stages of the production. The objective of the study is to examine the iron ore behavior front to different innovations in the collectors used in the stage of the reverse cationic flotation. The ore samples were obtained from the industrial processing plant. The studies had understood the evaluation of collecting different standard in use and the "taylor made" for each mine. The adopted experimental procedure considered standardized it for each mining. [ABSTRACT FROM AUTHOR]

Many transformation occurred in the industrial sector in the nineties, like technological changes to increase the competitive and thus could face more intense the external competition. These changes had caused an impact in the labor market. This paper has the proposal to analysis the industry labor market about the factors, which had influence in the numbers of the workers. The long-run relationship estimated cointegration vector between numbers of workers, wage, production installed capacity use, productivity. This vector is about the estimated elasticity of substitution between the capital and labor and price elasticity of labor demand. The results had been significant and the estimated of the price elasticity of labor demand was - 0.70816 (ηLL) and product demand labor elasticity was 1,607056 (η). [ABSTRACT FROM AUTHOR]
