Este artigo discute as dinâmicas de aglomeração industrial, incremento e modernização portuária no município de Barcarena, Estado do Pará, Brasil. Especificamente, discute as causas estruturais que explicam estas dinâmicas, e as mudanças qualitativas e quantitativas locais, acerca dos aspectos espaciais, sociais, demográficos e ambien-tais. Diferentes momentos de produção e exportação de produtos minerais (caulim, bauxita e produtos originados dela – alumina, alumínio) na Amazônia Oriental Brasileira levam a instalação, consolidação e expansão de um distrito industrial e portuário em Barcarena. Na atual década, Barcarena integra um corredor de exportação diretamente ligado a eixos ou sistemas produtivos nacionais e globais. Contudo, as dinâmicas que sustentam este crescimento econômico não apontam para perspectivas de que a produção conduza ao enraizamento social do desenvolvimento, ao estabelecimento de vantagens competitivas que tenham uma base sistêmica; tampouco contribui para a reversão dos impactos sociais e ambientais.

O presente trabalho faz análise, sob a égide do federalismo, da renúncia fiscal heterônoma do Imposto de Circulação de Mercadorias e Serviços (ICMS) para exportação introduzida pela Lei Federal Complementar n.º 87 de 13 de Setembro de 1996, Lei Kandir, posteriormente posta pela Emenda à Constituição de n.º 42/2003. Aborda aspectos da autonomia federativa dos Estados Membros, detentores da competência tributária de ICMS, e procura esclarecer os conceitos de imunidade e isenção tributária, competência e autonomia para verificar a possibilidade de violação à autonomia dos Estado mediante usurpação de competência tributária, bem como verificar as perdas fiscais decorrentes da referida renúncia fiscal no Estado do Pará.

Samples were collected from 100 carcasses in a slaughterhouse exporter, located within the State of São Paulo, sampled over a year through the sponge method, applied to the chest of the animal. Samples were taken at three points, denominated A, B and C, each carcass sampled at three points located in the following steps: after bleeding (A) after skinning (B) and after washing (C). Research was conducted for Listeria sp., E. coli O157, Salmonella spp. and Micro-organism (Petrifilms ® AC, EC and EB). Listeria or E. coli O157 were not isolated in any of the 300 samples. Salmonella spp. was isolated in nine, eight at point A and one at point B. For Mesophiles, scores ranged from 0 to 6.8 log UFC/cm²; for Total coliforms, 0 to 4.57 log UFC/cm² and E. coli from 0 to 4.38 log UFC/cm². With the results obtained and compared with the literature, it is concluded that the establishment in this study has both sanitary quality (due to the low prevalence of pathogens) and hygienic quality (due to the sharp decrease in the microbial load of indicators along the line.

Common bean grown in no-tillage (NT) systems has increased markedly in Brazil. Thus, to optimize the fertilizer recommendations, it is important to know the nutritional requirements of this crop when grown under new and established NT systems, which can change the nutrient availability and crop response to nitrogen (N) fertilization. The objective was to evaluate the extraction and exportation of nutrients by common bean as function of N fertilization on soil under new and established NT systems. The experiment was carried out in two agricultural years, on a Red Nitosol (Alfisol) in Botucatu, São Paulo State, Brazil. A randomized complete block design was used in a split-plot scheme with four replications. The plots consisted of areas under NT systems after different periods of adoption and the subplots of four forms of N application to common bean (T0: control, without nitrogen; T1: 60 kg ha-1 before sowing; T2: 60 kg ha-1 sidedressed at V4 stage; and T3: 60 kg ha-1 before sowing + 60 kg ha-1 sidedressed). The following properties were evaluated: shoot dry matter, nutrient concentration and accumulation in the shoot, grain yield, and nutrient concentration and exportation in the grains. The NT age did not affect common bean yield, nutrition and response to N management. Nitrogen application, especially before sowing, led to higher dry matter and nutrient accumulation by common bean. The nutrient concentration in grains was little influenced by N fertilization. Grain yield and nutrient exportation were highest after double N application (before sowing and sidedressed) or only sidedressed at V4.

O objetivo do presente trabalho é o entendimento da dinâmica do mercado dos alimentos orgânicos no Brasil, sua cadeia produtiva e as relações comerciais estabelecidas especificamente com a União Européia. Apesar do segmento orgânico crescer a altas taxas ao redor do mundo, ainda é uma temática (promissora) pouco estudada nacionalmente, o que dificulta o desenvolvimento de processos que poderiam diminuir os entraves enfrentados pelos produtores orgânicos. Inicialmente situando o leitor sobre as origens do cultivo orgânico e apresentando o panorama mundial atual, o trabalho entra no cenário nacional discutindo o perfil do produtor, o paralelo entre insumos tradicionais e aqueles específicos para a produção orgânica, além das dificuldades de financiamento em âmbito nacional. Em seguida, discute-se questões relativas à comercialização: qual o perfil do produtor e quais os sistemas de distribuição da produção orgânica nacional e internacional; o porquê dos preços de produtos orgânicos exibirem margens de lucro tão altas; de onde vem a necessidade de certificar a produção, quais as principais certificadoras e seus métodos de atuação. A partir deste embasamento, pode-se trabalhar, então, as relações comerciais estabelecidas entre o Brasil e a União Européia, bloco de destino de mais de 70% da produção orgânica nacional; trata-se, então, das leis e das certificações necessárias para efetuar as exportações; dos principais produtos exportados dentro do segmento orgânico e das 19 empresas responsáveis por essas exportações. Percebe-se, por fim, que um dos principais entraves ao desenvolvimento do segmento ainda é a falta de investimentos em P&D, pois a carência de dados sistematizados e pesquisas em geral acabam por desestimular tanto produtores quanto consumidores em busca de informações sobre esse mercado pouco evidenciado nacionalmente

The oil market is not a common market, and its complexity increases dramatically when considering the strategic and geopolitical involved, thus resulting in large uncertainties and concerns. The attempt to control prices has always been a challenge for the major world powers, since the increase in oil prices benefits the exporting countries, but harms importers, especially those regarded as less developed. Understand and try to predict some strategies adopted up the oil crises is one of the main points of the research, in order to demonstrate how economics can be used as an instrument of power and domination between nations, and how plans and strategies and rearrangements of supply and demand favor the growth of this economy, especially in the current period, with the new Brazilian oil era, beginning with the discovery of pre-salt, amid a context of growing need for the use of oil and its derivatives

With the increase of stakeholders and consequently increase of amount of nancial transaction the study of news investment strategies in the stock market with data mining techniques has been the target of important researches. It allows that great historical data base to be processed and analysed looking for pattern that can be used to take a decision in investments. With the idea of getting pro t more than the real indexs' gain, we propose a strategy method of transactions using rules built by algorithm classi cation. For that, diary historical data of Ibovespa index and Petrobras stocks are organized and processed to nding the most important attribute that act decisively when taking a investment decision.To test the accuracy of proposed rules, a non real portfolio management is created, showing the decisions' performance over the real index and stocks' performance. Following the proposed rules, the results show that the strategy of investment give me back a high return that Stock market's return. The exclusive characteristics of algorithms maximize the gain inside the analysed time allowing to determine the techniques' return and the number of the days necessary to double the initial investment. The best classi er applied on the time series and its use on the propose investments strategy will demand 104 days to double the initial capital

The implementation of an Export and Processing Zone (ZEPs) brings several benefits to the local, state and federal economy, but often, only socioeconomic factors are considered, apart from several other factors that should be analyzed, such as the environment. In this context of industrialization and the struggle for sustainable development, this work propose to incorporate the environmental variable in the decision process for establishing industrial areas, in particular, the ZPE in the city of Fernandópolis, São Paulo state, Brazil, by examining several physical and environmental factors such as slope intervals, geological features, pedological factors and land use. Developed using a multicriteria analysis, a model has been elaborated, where these factors have received a proportional value according with their importance, supported by a GIS tool (Geographical Information System) and remote sensing products, such as images from CBERS satellite and SRTM radar, showing the suited areas for industrial activities, considering environmental conditions. This model may assist to take better decision about the ZPE implementation area and to reduce the negative environmental impacts that would result of poorly planned locations

The right choose of the cultivar influences greatly the potato yield. It is very important to know its agronomic behavior in the region where it is planted, as well its nutritional status, in order to supply the best package in the fertilization operations. In this work the tuber yield, the nutritional status of plants and the exportation of nutrients were studied in eighteen potato cultivars. A randomized blocks experimental design, with four replicates, was used. Mondial showed the highest total and commercial yields. The nutrient concentrations in fourth leaf of potato plant followed the decreasing order: N>K>Ca>P>Mg>B>Zn. The exportation of nutrients by the tubers followed the decreasing order: K>N>P>Mg>Ca. B and Zn had different behavior according the cultivars.

This paper analyzed the energy flow of a route currently designed to transport ethanol from the Midwest region of Brazil for exportation, more precisely from the city of Aparecida do Taboado (MS) to the port of São Sebastiao (SP). The route studied a single modal combined into two pieces, duct - duct. The direct and indirect energy, involved in the operations were used to account for the inputs and outputs of energy from and into the system. The energy input and output were the variables, diesel fuel, lubricants, greases, indirect energy consumption of machinery and equipment, power consumption of labor, the energy consumption and energy consumption in depreciation and maintenance of roads. We found that this route has specific energy consumption of 0,14 MJ km-1 m-3 . The Net Energy Gain (GEl), the Energy Efficiency global (EEg) and Renewable Energy Balance (BEr), which were the energy indicators adopted in this study were obtained respectively: 1.585.958.977,00 MJ; 200,72 and 1.593.900.000,00MJ.
