    In recent years a trend on increasing requirements for local investments has been observed worldwide in the petroleum industry. Host countries expect to have increasing social and economical benefits from the development of the oil and gas industry. This expectation drives at a more comprehensive concept of local content to include commitment with social, industrial, and technological development. The Brazilian experience has shown a lot of emphasis on local industry development. Initiatives from governmental authorities and the private sector have been implemented to increase the local industry participation in the oil and gas projects. The current regulation focus on the full and fair opportunities for the local suppliers and the local content commitment established in the E and P concession agreements. A key issue on promoting local content initiatives is to assure that the competitiveness of the indigenous industry will be developed and preserved. The constraints on building up the local industry competitiveness will be addressed, focusing on the taxation overburden, lack of adequate local financing, and internal structural aspects affecting industrial productivity. In addition to this, the experiences on measuring local content for offshore construction and drilling are highlighted. Technology development and technical capability have been addressed by incentive programs for the O and G sector. Finally, the technology learning process and the regulatory requirements to invest in R and D programs conducted by Brazilian technological institutions are discussed. (author)

    In Brazil, the withdraw of 41 blocks of the 9th Round of Auctions by ANP rose questions about the possible unitization of oil fields, particularly on the pre-salt areas and the likelihood of future litigation from licensees against the Brazilian Government on the issue. Based on the international experience from Nigeria and East Timor/Australia, we propose improvements to the Brazilian law on the issue (Law 9478/97, article 27). We conclude that a clear and specific regulation on the unitization issue should be passed, so to protect investors and the non-renewable resources at stake (oil and gas). (author)

    This paper presents results of a survey, that among other subject matter approaches the model of farewell adopted by the National Agency of Oil Gas and Biofuels - ANP in Brazil. It is an analysis and discussion of evolution of the scenario of exploration and production of hydrocarbons in this country. In addition, it analyzes issues such as competition about farewell rounds and the reconfiguration of the upstream segment. The study is based on the methodology of the study-compared cases with focus in Brazilian and OCS-GOM-EUA auction models.The results of the study suggest that the model of granting the ANP produced: degree of concentration of business moderate to high, balancing of the reserves / production and strengthen the competitive capacity of PETROBRAS and considerable insertion of new entrants in the production chain, while political factors, Economic, social and technological developments have significantly affected the performance of rounds. Facing the new scenario of international prices, discoveries of large reserves and geopolitical issues the findings point to the need to consider possible exemptions to the model and suggests alternatives.

    Full Text Available Innovation is one important factor for companies. This study presents a longitudinal case study focusing on the learning processes associated to innovation on an oil industry company. To conduct the study, which was of exploratory nature, interviews were conducted with professionals connected to the history of the company. Reports about the processes of innovation were described by content analysis and related to: the types of innovation proposed by Schumpeter (1942; the types of learning proposed by Malerba (1992; the modes of learning single loop and double loop of Argyris and Schön (1978; the ways of knowledge conversion of Nonaka and Takeuchi (1997; and the creation of spaces of knowledge of Nonaka et. al (1998, 2000. The research results indicate that radical innovation tends to require a wider range of learning styles, if compared to incremental innovations. Still, the internalization and socialization seems to prevail in contexts of radical innovation, while externalization and combination are more frequent in incremental innovation contexts. Finally, the results point to the fact that the single loop learning is more directly related to incremental innovations, while the double loop learning is more present in radical innovation contexts.

    The resumption of the Brazilian Nuclear Program (BNP), in the proposed size and after 20 years of paralysis, requires profound changes in the current organizational modeling of the national nuclear industry. The effectiveness of any process of organizational change is limited to three factors. The theoretical bottleneck happens when you do not know enough about a phenomenon in order to effect the desired changes. The resource bottleneck occurs when knowledge may be available to change people's behavior but the funds necessary for implementation may be lacking. The organizational bottleneck emerges when there are knowledge and resources to solve a problem, but may not able to organize the resources in order to carry out the problem-solving effort. In the case of resumption of BNP seems clear that there is the knowledge of what is needed to make policy and the intention to allocate the necessary resources. But the question is the following: the current organizational model of the Brazilian nuclear sector is consistent with the goals laid down in the scenario of resumption of BNP? That is, is there organizational ability to leverage a program of the size proposed for the nuclear area? Find answers to these questions is crucial, because the organizational model of the Brazilian nuclear sector consists of elements involving a complex interorganizational system. Thus, this article is to examine the appropriateness of the current organizational modeling of the Brazilian nuclear sector to current demands of society. As a result, the article aims to propose recommendations for a remodeling of the nuclear sector, taking into account the current national and international scenarios of nuclear energy. (author)

  8. Discussing the inter-sectoral linkages in Ecuador, with a focus on the oil sector

    2015-12-01

    Full Text Available The oil sector represents a key-sector of the Ecuadorian economy, characterised by a high level of value added and a high weight in the national exports. This paper tries to find out whether the oil sector is able to induce positive effects for other economic sectors, and to also measure these effects in comparison with those generated by other sectors. The empirical analysis uses the income and employment multipliers, which are derived from Leontief Input-Output tables. The results indicate that the Ecuadorian oil sector is the most independent one, so that policies enhancing stronger linkages with other sectors are highly recommended.

  9. Development of Brazilian Biodiesel Sector from the Perspective of Stakeholders

    Full Text Available In Brazil, the main program with respect to biodiesel is the National Program of Biodiesel Production and Use (NPBP. It is also considered the regulation mark of biodiesel production in Brazil and its directives are social inclusion and regional development. Considering these directives, this paper aims to analyse the perspective of biodiesel sector stakeholders in Brazil to understand whether NPBP directives are in consonance with the reality of the sector for its development. A questionnaire was created with 48 questions in order to understand the importance of 13 variables for the stakeholders, and the responses were treated by factor analysis (FA. The results showed the existence of a trade-off related to technological advances in biodiesel production that confronts NPBP directives, that is, the biodiesel sector tends not to evolve in terms of the use of advanced technologies. If policies change so as to develop the biodiesel sector using advanced technologies, NPBP should change its directives in order to involve family farmers in another way in the Brazilian economy.

    2017-10-01

    Full Text Available Abstract Grape seed oil (GSO is an important by-product of the wine-making industry which has received attention as an alternative source of vegetable oils; its chemical compounds can be influenced by agricultural practices and industrial processing. Knowledge of the composition of Brazilian GSO is scarce; thus, this study aimed to analyze the chemical characteristics, as well as the antioxidant activity of these oils. GSO samples were obtained from Brazilian markets and showed significantly high amounts of phenolic, γ-tocotrienol and phytosterols as well as, the presence of several volatile compounds. Based on these results, is possible to show that oils exhibited good antioxidant activity. Therefore, it can be inferred that Brazilian GSO had a considerable content of phytochemical compounds with biological activity, which allows its association with other vegetable oils.

    This study focuses on the daytime medium-scale traveling ionospheric disturbances (MSTIDs) observed at conjugate hemispheres. It is the first time that the geomagnetical conjugate daytime MSTIDs are observed over the South America sector. To observe the MSTID characteristics, we used detrended total electron content (TEC) derived from Global Navigation Satellite Systems receivers located at Brazilian sector covering the Northern and Southern Hemispheres along the same magnetic meridian. The geographic grid of 1°N to 14°S in latitude and 60°S to 50°S in longitude was selected for this study. The cross-correlation method between two latitudes and longitudes in time was used to observe the propagation of the MSTID waves. The following features are noted: (a) MSTIDs are well developed at both hemispheres; (b) the peak MSTIDs amplitudes vary from one hemisphere to another; hence, we suppose that MSTIDs generated in Southern Hemisphere or Northern Hemisphere mirrored in the conjugate hemisphere; (c) the gravity wave-induced electric fields from one hemisphere map along the field lines and generate the mirrored MSTIDs in the conjugate region. To investigate the hemispheric mapping mechanism, a rough approximation for the integrated field line conductivity ratio of E and F regions is calculated using digisonde E and F region parameters. We noted that during the period of mapping the decrease in E region conductivity results in an increase in total conductivity. This shows that the E region was partially short circuited; hence, electric field generated at F region could map to the conjugate hemisphere during daytime: daytime MSTIDs at conjugate regions; mechanisms responsible for daytime electrified MSTIDs; gravity wave-induced electric field role in daytime MSTIDs.

    Distributed generation has become an alternative for the lack of resources to large energy projects and for recent facts that have changed the geopolitical panorama. The later have increased oil prices so that unconventional sources have become more and more feasible, which is an issue usually discussed in Europe and in USA. Brazil has followed such world trend by restructuring the electrical sector as well as major related institutions, from generation to commercialization and sector regulation while local legislation has enabled the increase of distributed generation. It regulates the role of the independent energy producer so as to provide direct business between the later and a great consumer, which is an essential step to enlarge energy market. Sugarcane bagasse has been used to produce both electric energy and steam and this paper analyzes and discusses the major implications of a new model for Brazilian electric sector based on sugarcane bagasse use as means to increase distributed generation process, particularly concerned with the commercialization of energy excess.

    To evaluate the chemical recycling of plastic residues, co-pyrolysis of polypropylene (PP) waste with Brazilian crude oil was evaluated varying the temperature (400°C to 500°C) and the amount of PP fed to the reactor. The co-pyrolysis of plastic waste in an inert atmosphere provided around 80% of oil pyrolytic, and of these, half represent the fraction of diesel oil. This study can be used as a reference in chemical recycling of plastics, specially associated with plastics co-pyrolysis.

    Reduction of CO2 emissions will require a transition from fossil fuels to alternative energy sources. Expansion of Brazilian sugarcane ethanol provides one near-term scalable solution to reduce CO2 emissions from the global transport sector. In contrast to corn ethanol, the Brazilian sugarcane ethanol system may offset 86% of CO2 emissions compared to oil use, and emissions resulting from land-use change to sugarcane are paid back in just 2-8 years. But, it has been uncertain how much further expansion is possible given increasing demand for food and animal feed, climate change impacts and protection of natural ecosystems. We show that Brazilian sugarcane ethanol can provide the equivalent of 3.63-12.77 Mb d-1 of crude oil by 2045 under projected climate change while protecting forests under conservation and accounting for future land demand for food and animal feed production. The corresponding range of CO2 offsets is 0.55-2.0 Gigatons yr-1. This would displace 3.8-13.7% of crude oil consumption and 1.5-5.6% of net CO2 emission globally relative to data for 2014.

    Indications are that the upward production trend in Saskatchewan's oil industry, evident in recent years, will be reversed in 2002. Predictions are that the drop in production will be a modest one, reflecting the slower economy and the lag time between drilling activity and produced barrels of oil. Also a contributing factor is the fact that the year 2001 marked a decline of 20 per cent in oil well drilling from the previous year, down from 2,401 wells drilled to 1,931 wells. Expansions of last year such as PanCanadian's carbon dioxide project, Husky Energy's heavy oil project at Pike's Peak, northeast of Lloydminster, PanCanadian's SAGD project, Conoco's project at the Kerrobert Pool and Apache Canada's Midale area project southeast of Regina, are all likely to see more modest development during 2002. Similar retrenchment is expected at Nexen's (Wascana) Williston Basin area operations, due in part to the increased drilling cost resulting from the intense activity during 2001, and a 5 to 10 per cent rise in operating costs.

    Full Text Available The study seeks to assess the structure of the economy of Ghana in terms of changes in the economic structure before and after the production of oil in commercial quantities. This is viewed with regards to economic multipliers, sectoral interdependence and trade concentration. The results show that changes occurred with regards to multipliers and sectoral interdependence. The output multipliers of most sectors have declined. The results also show that the agricultural sector experienced an initial decline in its growth while industry experienced an increase. The performance of the services sector was relatively stable for the period covered by the study. There is a decline in the level of trade concentration though on a whole the concentration index is still high. The study employed input-output modeling techniques and the data was obtained from the Ghana statistical service and the World Development Indicators.

  1. Corporate takeovers in the US oil and gas sector

    2016-03-01

    Full Text Available We examine corporate takeovers in the U.S. oil and gas sector from 1990 to 2008. We test the hypotheses that energy prices and reserves influence takeovers in the energy market for corporate control. We employ these methods: 1. capital asset pricing model, 2. regression analysis, and 3. Granger causality test. Our results show that oil reserves cause takeover deals and affect the value of the merger. High oil prices propel management to acquire oil firms as well as affect the target value. However, the reverse cause-effect mechanism occurs for natural gas prices. That is, takeover activity causes gas prices to decrease. Acquirers are motivated to purchase reserves; whereas, targets are disposed to sell based on energy prices. Hence, our findings imply that countries can consider policies, which address the motivations of the oil and gas industries to facilitate well-functioning takeover markets.

    The objective of this work is to evaluate current emissions of GHGs within the Brazilian oil and gas industry, specifically the fugitive emissions arising from exploration and production. Besides, projects for mitigating these emissions and opportunities for the national industry are investigated. Results show that N{sub 2}O contributes little to fugitive emissions from the oil and gas industry, principally from gas sector. NMVOC emissions are significant, principally from the oil sector. In relation to CO{sub 2} and CH{sub 4} emissions, the oil sector emits more CO{sub 2} while the gas sector contributes more to CH{sub 4} emissions. In both sectors flaring is the activity that emits most CO{sub 2}. In relation to CH{sub 4} the principal contribution to emissions are from exploration and production onshore, although offshore activities as a whole play a greater part in the national industry. The results make it clear that the use of gas from flaring activity is a great opportunity for emission mitigation projects. From a business point of view, methane emissions could mean lost opportunities in selling natural gas. The Kyoto Protocol mechanisms, as the Clean Development Mechanism and Joint Implementation actions, provide the opportunity to stimulate investments in projects for reducing flaring and venting of associated gas.

    Since the early nineties Brazil has initiated a program of reforms in its electric sector which includes utility privatization, de-verticalization. The main objectives were to promote a market-oriented energy industry attractive to private investments. This has led to the loss of sponsorship for the public-interest programs formerly undertaken by the state utilities. In particular, of significant concern are the programs for promotion of energy efficiency, renewable energy technologies, rural electrification and environmental protection. In the midst of the privatization effort, the National Agency for Electrical Energy ANEEL was created (end of 1997). One of the tasks of the regulatory agency is to provide funds and incentives to energy conservation. In this paper we review the role of ANEEL in promoting energy efficiency investments in the context of a market-oriented sector, its limitations and prospects.

    Full Text Available The objective of this article is to verify the degree of full adhesion and Effective Disclosure for business sectors in Brazil for oil, gas, and biofuel; and utilities, through sustainability reports prepared by the G3 version of the GRI Guidelines. The report of the Global Reporting Initiative (GRI is constituted by a set of principles and indicators of economic, social, and environmental concerns with emphasis on transparency, quality, and reliability. This paper develops a multi-case methodology using a qualitative approach and has an exploratory purpose concerning the compliance of the reports of Brazilian companies to the parameters of the GRI. We opted for the use of a non-probabilistic sample of Brazilian companies in two Brazilian sectors, namely oil, gas, and biofuel; and utilities. Then we obtained sustainability reports which provided the summary index of the indicators from the institutional page of each company on the internet. From these observations we found that some Brazilian companies are adhering to the use of indicators of Sustainability Reports proposed by GRI. Furthermore, we found that the fact that companies are part of the same economic sector implies they are at a similar level of adherence to the indicators. Also, we observed that despite the effort postulated by GRI to develop a quality model more consistent and complete for sustainability reports, its applicability in the Brazilian oil, gas, and biofuel; and utility industries still needs to be improved.

  6. Tax effort and oil royalties in the Brazilian municipalities

    Fernando Antonio Slaibe Postali

    2015-09-01

    Full Text Available This paper estimates a stochastic production frontier, to investigate whether municipalities covered by oil royalties in the last decade have reduced their tax effort in Brazil. The issue is relevant to the prospect of a substantial increase in these revenues and the new rules for distribution of the funds, established by Law No. 12.734/2012. The inputs were provided by personnel and capital expenditures, whereas the product was defined as the municipal tax collection. With the purpose of overcoming the endogeneity problems due to reverse causality of output on inputs, we used the lagged independent variable as instruments in the inefficiency equation. The data set is composed of a panel of Brazilian municipalities from 2002 to 2011. The results indicate that oil revenues have a negative impact on the estimated efficiencies, signaling reduced fiscal effort by the benefiting municipalities.

    Adriano Filipe da Silva Maia

    2014-11-01

    Full Text Available This paper discusses the sectoral differences in the innovation activity in Brazilian small industrial firms. It starts with the hypothesis, originally developed by Pavitt (1984, that there is sectoral heterogeneity in the generation of innovations process, regarding the knowledge sources and the cooperation relationships as well as the results in terms of rates of product and process innovation. In this work we use data from the Pesquisa de Inovação Tecnológica (PINTEC released by the Instituto Brasileiro de Geografia e Estatística (IBGE for the year 2008. By using a tabulation specifically developed for this study, we present the data displayed by firm size and sector. The results confirm the main hypothesis and show that the innovative behavior of small firms should be apprehended in the light of the sectoral specific features that underlie the innovation activity, results which are consistent with the propositions of the literature.

    Full Text Available ABSTRACT OBJECTIVE To provide insights for nutrition and public health practitioners on how to engage with other sectors to achieve public health goals. Specifically, this study provides lessons from the example of integrating family farming and a nutrition into a legal framework in Brazil on how to successfully shift other sectors toward nutrition goals. METHODS The study analyzed policy processes that led to a Brazilian law linking family farming with the National School Feeding Program. Main actors involved with the development of the law were interviewed and their narratives were analyzed using a well-established theoretical framework. RESULTS The study provides five key lessons for promoting intersectorality. First, nutrition and health practitioners can afford to embrace bold ideas when working with other sectors. Second, they should engage with more powerful sectors (or subsectors and position nutrition goals as providing solutions that meet the interests of these sector. Third is the need to focus on a common goal – which may not be explicitly nutrition-related – as the focus of the intersectoral action. Fourth, philosophical, political, and governance spaces are needed to bring together different sectors. Fifth, evidence on the success of the intersectoral approach increases the acceptance of the process. CONCLUSIONS This study on policy processes shows how a convergence of factors enabled a link between family farming and school feeding in Brazil. It highlights that there are strategies to engage other sectors toward nutrition goals which provides benefits for all sectors involved.

    Full Text Available echnology is one of the most relevant conditions for progress and development in society. Industrial technology generated a new development curve in several productive sectors, such as the alcoholic beverages. Beer is produced since 8000 BC, but its global popularization took place after the Second World War. Yet, brewing technology has been recently writing a new chapter: a paradigmatic transformation not only on instrumental principles, but also in terms of its economic and symbolic impact inside and outside organizations. This article aims to explore the new brewing paradigm and its pragmatic implications in terms of main concepts, management and operations in Brazil. Secondly, as a theoretical approach, it seeks to demystify technology and its social relationship. Technology, considering its material aspect, does not provide a broad understanding of field transformation. Therefore, the nuances of brewinng technology were captured by qualitative research. Secondary data and interviews with key elements were used as the main data collection strategy. Results indicate a brewing revolution, materialized by the offer of creative new products to mainstream markets, specialty beer shops and pubs. It is technological transformation in its essence, creating a new path from the craftman to the technique and demanding innovative management and operations forms. New brewing technologic paradigm rescues traditional techniques that in essence are concerned with producing “good” beer.

  11. Technological and Productive Density in Sectoral Innovation Systems: The Case of the Brazilian Aeronautics Industry

    Directory of Open Access Journals (Sweden)

    Marcio da Silveira Luz

    2011-11-01

    Full Text Available This article discusses whether a globally competitive high-tech firm is sustainable without being associated with a sufficiently dense sectoral innovation system. It focuses on Embraer and hence on the Brazilian aeronautics industry. Despite not benefiting from a highly subsidized process for technological and financial modernization, Embraer has become the world’s third-ranking producer of commercial jets thanks to institutional innovations, especially in producing and managing contracts with suppliers and risk-sharing partners. The conclusion drawn is that the competitiveness of the Brazilian aircraft industry depends on the continuing supply of technology in international markets. Technological restrictions imposed for geopolitical reasons, or even for market constraints, could fatally undermine the strategy adopted by the company.

  13. ASSESSMENT OF CO2 EMISSION MITIGATION FOR A BRAZILIAN OIL REFINERY

    Directory of Open Access Journals (Sweden)

    W. N. Chan

    Full Text Available Abstract Currently the oil refining sector is responsible for approximately 5% of the total Brazilian energy related CO2 emissions. Possibilities to reduce CO2 emissions and related costs at the largest Brazilian refinery have been estimated. The abatement costs related to energy saving options are negative, meaning that feasibility exists without specific income due to emission reductions. The assessment shows that short-term mitigation options, i.e., fuel substitution and energy efficiency measures, could reduce CO2 emissions by 6% of the total current refinery emissions. It is further shown that carbon capture and storage offers the greatest potential for more significant emission reductions in the longer term (up to 43%, but costs in the range of 64 to162 US$/t CO2, depending on the CO2 emission source (regenerators of FCC units or hydrogen production units and the CO2 capture technology considered (oxyfuel combustion or post-combustion. Effects of uncertainties in key parameters on abatement costs are also evaluated via sensitivity analysis.

  14. Industralization plan in the oil sector in Abu Dhabi

    Energy Technology Data Exchange (ETDEWEB)

    1981-05-01

    Abu Dhabi's oil discoveries are changing a simple tribal community into an industrial society. The socio-economic changes and the infrastructure needs associated with rapid economic development are largely the responsibility of the public sector, while Abu Dhabi National Oil Company (AGNOC) and its partners focus on an exploration and development program that will conserve natural resources. ADNOC companies provide three types of petroleum services: exploration and production, transportation and distribution, and marine services. ADNOC projects completed, under completion, committed and under study are summarized. Projects in transportation and telecommunications networks, utilities, and housing reflect government-industry cooperation. The country also encourages the joint-venture participation of foreign countries as long as there is an equitable sharing of risks and benefits. (DCK)

    2012-01-01

    Full Text Available Crude oil price is a critical cost factor for manufacturing industries that are of vital importance for economic growth. This study examines the relationship between crude oil prices and the indices of seven Turkish manufacturing sub-sectors over the period 1997:01-2009:12. The error correction model results reveal the long term causality from crude oil prices to chemical petroleum-plastic and basic metal sub-sectors indicating that these sub-sectors are highly sensitive to crude oil prices. We find no causal relationship for other sector indices for short or long time periods.

  18. Ionospheric Effects of X-Ray Solar Bursts in the Brazilian Sector

    2011-12-01

    When the solar X-ray flux in the interplanetary medium reaches values above a certain threshold, some undesired effects affecting radio communications are expected. Basically, the magnitudes of these effects depend on the X-ray peak brightness and duration, which drive the intensity of the ionosphere response when the associated electromagnetic wave hit the sunlit side of the Earth atmosphere. An important aspect defining the severity of damages to HF radio communications and LF navigation signals in a certain area is the local time when each event takes place. In order to create more accurate warnings referred to possible radio signal loss or degradation in the Brazilian sector, we analyze TEC maps obtained by a GPS network, formed by dual-frequency receivers spread all over the country, to observe ionospheric local changes during several X-ray events in the 0.1-0.8 nm range measured by GOES satellite. Considering the duration, peak brightness, and local time of the events, the final purpose of this study is to understand and predict the degree of changes suffered by the ionosphere during these X-ray bursts. We intend using these results to create a radio blackout warning product to be offered by the Brazilian space weather program named EMBRACE (Estudo e Monitoramento BRAsileiro do Clima Espacial): Brazilian Monitoring and Study of Space Weather.

  19. Materiality in Public Sector Financial Audit: International Practice and the Opinion of Brazilian Experts

    Full Text Available Materiality in private sector financial audit is a topic that has been relatively well developed in the literature. Specific research in this regard in public sector auditing, on the other hand, is scarce at the international level and absent in Brazil. In view of this, the purpose of this study was to identify the parameters used to determine materiality in public sector financial audit. To this end, we sent questionnaires to the 192 Supreme Audit Institutions that are members of INTOSAI and to 36 Brazilian public auditors, specialists in financial audit, who are staff members of the TCU or the CGU seeking information with respect to the Institutions’ guidelines and the auditors’ perceptions about materiality. Results reveal that expenditures, revenues and total assets are the benchmarks most recommended by respondents for defining materiality in the public sector. In addition, they recommended the adoption of percentages of up to 2% for each of these parameters in defining what is material. It was observed, as well, especially with respect to the effectiveness of internal control and to public expectations or interests, that qualitative aspects should be also taken into account in determining materiality, although a lesser degree of importance is attributed to this than to the quantitative aspects,. The study contributes to the accounting literature on the development of audits, particularly with respect to the use of a concept, materiality, that is always emphasized in professional standards, but about which there are few objective guidelines.

    2011-01-01

    Full Text Available This article presents the results of a research to understand the conditions of interaction between work and three specific information systems (ISs used in the Brazilian banking sector. We sought to understand how systems are redesigned in work practices, and how work is modified by the insertion of new systems. Data gathering included 46 semi-structured interviews, together with an analysis of system-related documents. We tried to identify what is behind the practices that modify the ISs and work. The data analysis revealed an operating structure: a combination of different practices ensuring that the interaction between agents and systems will take place. We discovered a structure of reciprocal conversion caused by the increased technical skills of the agent and the humanization of the systems. It is through ongoing adjustment between work and ISs that technology is tailored to the context and people become more prepared to handle with technology.

    This article describes the competitive strategies of the subsystems in the Brazilian electricity sector. The objective is to present a model in which the operation of each subsystem is managed independently. As the subsystems correspond to the country's geographic regions, the adoption of this model creates conditions for each region to develop according to its own peculiarities. The decision-making process is described based Game Theory. As such, the players or operators of each subsystem carry out their strategies based on the quantities produced, which results in Nash-Cournot equilibrium. In this model, the importance of the proper transmission line dimensioning is highlighted. It determines the competition level among subsystems and allows for optimization of the whole system without requiring arrangements for managing the congestion of the energy transportation grid. The model was programmed in FORTRAN, using IBM's optimization subroutine library (OSL) package.

    2010-11-01

    Full Text Available The article analyzes the internationalization strategies of the four largest Brazilian companies in the meat (beef, pork and poultry agribusiness sector, by considering the comparative and competitive advantages of the country and the companies. JBS, Marfrig, Sadia and Perdigão were studied, of which the last two merged in May 2009, forming Brasil Foods. The authors looked into what led these companies to start investing  abroad directly, as from 2005, as a complement to their exports, the preferred strategy for placing products in foreign markets. The research method used was the multiple case study, drawing on primary data (interviews, corporate annual reports, financial statements, press releases and shareholder information and secondary data (theses, dissertations, academic articles, reports in newspapers and business journals, using bibliographic and documentary research. Everything was analyzed in the light of international business and strategy theories. The results show that exports still predominate and that investing directly abroad was, in principle, a reactive strategy to sanitary barriers against Brazilian products. However, the acquisition of companies in restriction-free countries has increased as part of a forward-looking strategy for gaining access to new markets and strengthening brands. Key-words: Agribusiness.

    Full Text Available In the present work we show new results regarding equatorial counter electrojet (CEJ events in the Brazilian sector, based on the RESCO radar, two set of fluxgate magnetometer systems and a digital sounder. RESCO radar is a 50 MHz backscatter coherent radar installed in 1998 at São Luís (SLZ, 2.33° S, 44.60° W, an equatorial site. The Digital sounder routinely monitors the electron density profile at the radar site. The magnetometer systems are fluxgate-type installed at SLZ and Eusébio (EUS, 03.89° S, 38.44° W. From the difference between the horizontal component of magnetic field at SLZ station and the same component at EUS (EEJ ground strength several cases of westward morning electrojet and its normal inversion to the eastward equatorial electrojet (EEJ have been observed. Also, the EEJ ground strength has shown some cases of CEJ events, which been detected with the RESCO radar too. Detection of these events were investigated with respect to their time and height of occurrence, correlation with sporadic E (Es layers at the same time, and their spectral characteristics as well as the radar echo power intensity.

    2010-08-15

    This paper examines the impacts of world, country, and sector-specific variables on the stock return volatility of twenty-seven US sectors in the short- and long-run, accounting for the asymmetric shocks based on GARCH models. In the standard GARCH model the two world variables, oil and Morgan Stanley Capital Index (MSCI), have differing impacts on the US equity sector returns' volatility, with oil price dampening it while MSCI heightening it for most sectors. This result underlines the need for hedging more against world capital market risk relative to oil risk which is probably hedged by many sectors. The world and country factors' impacts are not as pervasive across the board, compared with the sector-specific impacts of the P/B ratio and trading volume which affect almost all sectors. Increases in the P/B ratio would reduce the aggregate volatility, while increases in the trading volume would heighten it for all sectors. Asymmetry of factor impacts on volatility is also found for most sectors. Most of the GARCH factor results are confirmed in the CGARCH model with the exception of the impact of interest rate on the short-lived transitory volatility. Finally, interesting econometric results on the inclusion or exclusion of trading volumes are discussed. (author)

    Full Text Available Associating the global trend of incorporating active compounds and plants in cosmetic formulations and the vast Brazilian biodiversity, the present work aimed to study the incorporation of Brazilian vegetable oils in hair conditioner formulations, evaluating the mechanical resistance of hair fibers. The following oils were incorporated into base formulations at 5.0 % (w/w: babassu, buriti, andiroba and pequi. The formulations were applied to samples of Caucasian hair, followed by several washing steps, then the evaluation of mechanical strength. It was found that there was no statistically significant difference in mechanical resistance between samples treated with oils and the control between the first and seventh wash cycles. This fact can be explained by the possible low penetration of oils into the cortex, a region responsible for the mechanical properties of the hair fiber, since the grease composition disfavors its diffusion. The common effects of vegetable oils on the cuticle, such as filling in cracks or cavities, lubrication, and increased protein hydrophobicity cannot be excluded. The oils tested in this work were not able to raise or protect hair tresses. However, additional studies are required in order to establish the effects of oil treatments, particularly in damaged hair.

    Full Text Available ABSTRACT: The purpose of this study was to evaluate the effects of feeding pigs with diets containing increasing levels of Brazilian red pepper essential oil ( Schinus terebinthifolius Raddi on the physical attributes, fatty acid profile and oxidative stability of precooked meat. Seventy-two weanling pigs (5.7±0.8kg were allotted in a completely randomized block design experiment with four treatments, six replicates per treatment, and three animals per experimental unit (pen. Animals were fed with a basal diet supplemented with 0, 500, 1,000, or 1,500mg kg-1 Brazilian red pepper essential oil during the 35-d experimental period. At the end of the experiment, one animal per experimental unit (16.4±2.2kg was slaughtered to sample Longissimus dorsi muscle for analysis. Dietary supplementation of Brazilian red pepper had no effect (P>0.05 on pork meat color, pH, cooking loss and shear force. Inclusion of essential oil in the diet provided a linear increase (P<0.05 of the saturated fatty acids content of L. dorsi, especially myristic (C14:0 and stearic (C18:0 fatty acids. Utilization of essential oil in pig diets reduced significantly the production of secondary lipid oxidation compounds measured as TBARS in raw pork meat (P<0.001 and immediately after cooking (P<0.001. However, during 8-d storage assay, the addition of essential oil in the diet did not protect pork meat lipids from oxidation. Therefore, Brazilian red pepper added to pig diets increased the saturated fatty acids content and reduced lipid oxidation in fresh meat and short-term heat treatment without affecting pork meat physical attributes.

    This thesis analyses the role of free consumers in the Brazilian Electric Power Sector. Therefore, it evaluates the role of free consumers in other markets worldwide and analyses the current Brazilian regulatory framework that was introduced in 2004. The current model has replaced the one adopted in the 1990s, when the first reform of the Brazilian Electricity Sector occurred. To assess the role of free consumers in the electricity sector, this work analyses the benefits that this kind of consumers perceive and the risks they are exposed to when they switch from the captive market and go towards the open market. It also evaluates the influence of free consumers over the other industry agents: generators, distributors, retail consumers and society. It also identifies new options for free consumers in the Brazilian electric energy (author)

    2007-01-01

    Full Text Available This paper presents a spatial price equilibrium model in an oligopoly market for refined oil products. Till 1997 the Brazilian oil market was characterized by the state monopoly of Petrobras, which up to 2001 remained the only firm authorized to import oil derivatives. With several agents operating in the primary oil supply market, the government stopped fixing the prices for Petrobras, which started to determine the prices based on competition with other players. In this new scenario some questions arise regarding the price levels at which refined products will be supplied in different regions across Brazil as well as the capacity of national refineries to compete with imported products. To answer those and other questions, a new oligopoly spatial equilibrium model is herein proposed, taking into account the special characteristics of production of refined oil products. An iterative Gauss-Seidel-like algorithm with sequential adjustments was developed and applied to Brazilian market data. The model, the algorithm and its application are described in this work. Such a model may be used both by regulatory authorities and by companies in the sector.Este artigo apresenta um modelo de equilíbrio espacial de preços em um mercado oligopolizado de derivados de petróleo.

Com vários agentes operando no mercado, o governo deixou de fixar os preços para a Petrobrás, que passou a determinar os preços baseada na competição com outros agentes. Neste cenário, surgem algumas questões relativas aos níveis de preços a serem oferecidos no mercado e relativas à capacidade das refinarias nacionais de competir com produtos importados.

    Full Text Available This paper investigates the impact of the new oil sector on the economic performance of major traditional sectors of the Ghanaian economy. The discovery of resource booming sectors in most countries often comes with several opportunities as well as challenges. Ghana discovered oil in 2007 and started subsequent commercial production and export in 2010. The results from the study show that, there is no clear case of declining performance of sectors in terms of output, growth and export earnings as a result of the oil production. The study could also not establish a sustained appreciation in the real effective exchange rate since commercial oil production commenced which is an indicator of the presence of the Dutch Disease phenomenon. The real effective exchange rate was also found to be highly influenced by oil production, oil prices, total exports and remittances. The study applied an autoregressive distributed lag model due to differences in the level of integration of variables. The data was obtained from the Bank of Ghana, the Ministry of Finance in Ghana and the Energy Information Administration.

    The use of mind maps as a method of building knowledge, planning, organizing activities and ideas can be seen in the literature related to ergonomics. The results of such use are relevant and its use in academic area found. However, regarding to its use in industrial environments, studies can't not be found. With this scenario, and based on the perception of the ergonomist about the importance of using methods such as mind maps in support of human cognition, it seems pertinent to its use in industry sectors whose cognitive demand requires. Given these assumptions, this study aimed to apply the method of Mind Maps in Productive Maintenance sector of a Brazilian paper. The Productive Maintenance sector in the Paper Industry has an important contribution to operational performance. With practical Predictive Maintenance, Preventive Maintenance and Corrective Maintenance, the industry advocates to make the machines to produce paper is not to stop producing when they are programmed to do so. Among the practices cited, the Preventive Maintenance is one that leads to pre-determined intervals in order to reduce the possibility of placing the equipment in a condition below the required level of acceptance. Therefore, this article aims to propose using the tool "mental maps" in order to collaborate in planning and implementation of preventive maintenance activities in the sector of mechanical maintenance of a pulp and paper industry in southern Brazil. The study investigated the maintenance sector through its employees, who went through training about the tool and then use it and ergonomists company.

    Full Text Available In this paper, we consider identifying features of sectoral structuring within the national economy that has definite foreign trade product specialization. Examination of the sector-specific division methodology enabled identification of its strong association with certain sector dominance in the economy. It is against this background that we offer an explanation for the delay in transferring from the post-Soviet to the applicable international classification of economic structure elements in Russia and Belarus. We perform analysis of the three-component P-S-T model (primary, secondary, tertiary sector using statistical and econometric methods and define properties of the sectoral shares dynamics in national economies of oil and gas producing countries. Analysis of the Russian and Norwegian economies’ intersectoral changes suggests that it is necessary for the government to develop and implement selective structural policy to overcome the existing structural disproportions.

    The present study investigates the ionospheric F region response in the Brazilian sector due to sudden stratospheric warming (SSW) events of 2014. The data used for this work are obtained from GPS receivers and magnetometer measurements during day of year (DOY) 01 to 120, 2014 at different stations in the equatorial and low-latitude regions in the Brazilian sector. In addition, the data obtained from Communication/Navigation Outage Forecasting System satellites during DOY 01 to 75 of 2014 are used. The main novelty of this research is that, during the 2014 SSW events, daytime vertical total electron content (VTEC) shows a strong increase on the order of about 23% and 11% over the equatorial and low-latitude regions, respectively. We also observed that the nighttime VTEC (SSW days) is increased by 8% and 33% over equatorial and low-latitude regions, respectively. The magnetometer measurements show a strong counterelectrojet during the SSW days. The results show an amplification of the 0.5 day and 2-16 day periods in the VTEC and equatorial electrojet during the SSWs. The occurrences of ionospheric irregularities during the SSW events are around 84% and 53% in the equatorial and low-latitude regions, respectively, which is less frequent when compared with those during the pre-SSW periods.

    In the sector of oil bleaching, the stored raw oil is subjected to physical and chemical methods such as degumming, neutralization, bleaching, deodorization and winterization. In the process of oil bleaching, the selection of correct bleaching earth in accordance with oil characteristics matters so much. Bleaching earth is an inorganic product used in removing impurities being available within the structures of vegetable, animal oil (sunflower, soya, corn, palm, tallow, rapeseed, fish oils…etc.) and fatty acids, mineral oils (glycerine, paraffin, mineral motor oils. etc.) with the adsorption process. The factors such as low cost of oil bleaching earth, low ratio of oil retaining, high bleaching capacity in spite of using them in small amounts, filter’s delayed blocking by the earth and non-increase of the free acidity of the oil should be taken into consideration. Bleaching earths are processed with some acids in order to widen their surface areas. During this process, a certain amount of acid is left within oil bleaching earths even if it is very little. These acids also increase oil’s acidity by oxidizing oil in the course of bleaching process. In this study, zeolite sample taken from Manisa -Demirci region was used. Following the processes of crushing and sieving, zeolite sample was subjected to chemical analyses according to their grain thickness, microscopic examination, the analyses of XRD and cation exchange capacity and their ore characteristics were determined. Afterwards, it was searched whether zeolite sample has oil bleaching ability or not or whether it can be used as oil bleaching earth or not.

    Full Text Available The production of essential oils from the species of the Brazilian native forests is still low, even thought its high biodiversity. Specifically for the Brazilian Savannah, a few species has been studied so far, then the research effort concerning essential oil should be raised. This paper aimed at evaluating the potential of some species from the Brazilian Savannah to produce essential oil by calculating the yield and determining the preliminary chemical composition. Leaves from Baccharis sp., Blepharocalyx salicifolius, Psidium myrcinides and Protium ovatum were collected at Fazenda Água Limpa, the ecologic experimental area of the University of Brasília. The essential oil from the material was extracted by steam distillation for 90 minutes, using laboratory distillatory equipment. The fresh distillate was collected and the essential oil was separated from the hydrosol by using a solvent. The preliminary chemical composition of the essential oils was determined by TLC (thin layer chromatography and 1H and 13C Nuclear Magnetic Ressonance (NMR and Infrared (IR analyses. According to the results the essential oil yield of Baccharis sp., Blepharocalyx salicifolius, Psidium myrcinides and Protium ovatum was 0.06%, 0.12%, 0.10% and 0.13%, respectively. The observed yield values can be considered suitable for maintaining the research efforts. Chemical analysis showed that the essential oils obtained are composed by a complex mixture of compounds which should be studied more deeply.

    Arab countries face the corruption issues in its several public organizations. The corruption in these countries is considered as the main challenge. The oil sector is one of the public sectors that have huge level of corruption. However, the Iraqi economy had become dependable on oil sector daring the last three decades, and on the contrary, of what other oil countries did. The capital is considered as one of the essential factor for economic development. The revenues of oil exports will stay the essential source for economic development in Iraq in the future in order to reduce being dependable on oil. Since the beginning of the 3rd thousands, the world witnessed great rise in the demand on oil, but the Iraqi exports of crude oil come to be less than its similarities in the seventeenths of last century. So our oil sector is still in need of deep study. This study focuses on technological technique that can make huge decrease for corruption in oil sector in Iraq. However, e-government is considered as the best techniques that can decrease the corruption. Thus, this study bases on challenges that effect on build successful e-government project in Iraqi oil industry.

    The need to continuously improve the aspects of Health, Safety and Environment to operators, installation's security, optimization of oil reservoir recovery in wells operating with different artificial lift methods, subject to different secondary recovery techniques, has motivated the development of technologies in the automation and control for the upstream sector of the oil industry. While the application of control and automation techniques is well established in the downstream sector of the oil industry that is not the case in the downstream sector. One tendency in this sector is the utilization of control via Field bus Networks. This technology uses equipment that communicate with each other in a two wire digital network and can be programmed to execute function blocks algorithms designed to perform a designed control strategy. The most noticeable benefits are the improvements in the process performance and the equipment reusability and interoperability. Proprietary solutions can be replaced by systems composed of equipment supplied by different manufacturers connected in the same network. These equipment operate according to a strategy designed by automation and control engineers under the supervision of professionals working in computer terminals located in different company departments. Other gains are a better understanding about the industry processes, application of optimization techniques, fault detection, equipment maintenance follow-up, and improved operators working conditions and workers qualification. Other tendencies are: permanent well monitoring. Either with installation of down hole sensors based on fiber grating sensors or surface sensors using embedded electronic processors. Developments of instrumentation technology for low cost multiphase flow measurements. Application of control techniques for flow regime control and optimization of reservoir recovery through better identification, optimization and Model Based Predictive Control

    Full Text Available The present study is an evaluation of the current strengths and weaknesses of the oil palm smallholder sector in Cameroon, or more precisely of the non-industrial sector, as some holdings owned by elites can reach hundreds of hectares. A randomized sample of oil palm producers was chosen after categorization into elites, migrants, natives and company workers (past and present in four palm oil production basins in the Southern part of the country. 176 semi-structured questionnaires were administered. The production basins included: Eseka, Dibombari, Muyuka, and Lobe. Results from the study revealed that elites owned larger average areas (41.3 ha than the other categories of oil palm producers. All categories recorded low average plantation yields, ranging from 7 to 8.4 t FFB/ha/year (with minimum yields of 3 t FFB/ha. Though the elites showed better bargaining power and higher income, all categories of producers faced similar problems such as the high cost of inputs with no governmental subsidies, the difficulty in accessing loans with low interest rates and the use of rudimentary working tools. Despite such weaknesses, the sector also demonstrates some strengths such as the ability to impose little threat to the primary forest when compared to agro-industrial plantations, the availability of a domestic and sub-regional market for red palm oil, the availability of artisanal mills with low extraction rates although able to generate more income for the producers. There is a need for governmental policies that will strengthen partnership between small and medium oil palm producers and agro-industries as it was the case during the Fonader period, in order to converge with the poverty reduction strategy intiated by the government of Cameroon.

  5. Power and selection of contract terms: The case from the Brazilian orange juice sector

    Directory of Open Access Journals (Sweden)

    Nobuiuki Costa Ito

    2016-03-01

    Full Text Available ABSTRACT We propose a model to explain how contract terms are selected in the presence of a form of economic power: contract power. The orange juice sector is used to illustrate an analysis that demonstrates the effects of contract power on the economic organization of the sector. We define contract power as the ability to exploit contractual gaps or failures of contractual provisions, which are strategically left incomplete. Empirical evidence from content analysis of antitrust documents supports the logic of contract power in the orange juice sector in three forms: avoiding changes to payment methods from weight to solid contents (quality; using information asymmetries to manipulate indexes that calculate the formula of orange prices; and deliberately harvesting oranges late in order to dehydrate the fruit, which consequently reduces weight and price. The paper contributes to understanding the selection of contract terms and the debate about how antitrust offices can deal with this issue.

    Full Text Available Strategic change has been a subject in evidence in organizational studies. In recent years, the concept of strategy has evolved from a purely static to a more dynamic point of view, renewing the research agenda on this subject. Thus, this article aims to analyze the strategic change that occurred in a state-owned Brazilian Electric Sector (SEB, using for that, the theory of coevolution as a conceptual framework. Most research about processes of change focuses on private organizations. Therefore, the analysis of strategic change in a state-owned company reveals peculiarities that are not usually addressed in the literature. Furthermore, the theory of coevolution, unlike other theories of analysis, adopts an integrated view on the issue of adaptation of organizations in relation to their environment, thus broadening the understanding of the phenomenon of strategic change. The research was characterized as a case study descriptive and longitudinal. Data were collected through semi-structured interviews, direct observation and document analysis. The results showed that the change in the company occurred in a coevolutionary process involving the competitive dynamics of the sector and institutional system in which organizations and industries interact with each other. The theory of coevolution demonstrated its potential to show results that would normally be withheld if it was adopted a narrower perspective of analysis.

    The Bolivia oil industry nationalization in 2006 and the high price of oil on the international market called the public and government attention to the problems of the natural gas industry regulation in Brazil. Recently, the establishment of a specific law for the natural gas industry had been debated in academic circles and in government institutions. In Brazil, the absence of an integrated energy policy and the absence of a homogeneous regulatory framework interfere with natural gas industry development, especially in distribution. Thus, the objective of the work will be contrast the Colombia distribution natural gas regulatory structure sector to the Brazilian natural gas regulatory framework. The comparison of the Brazilian regulatory framework and the Colombian natural gas regulation shows that the existence of different kinds of concession contracts in distribution is one of the explanations for the different levels of investment in Brazil. The contract with exclusive right to explore the distribution service in geographic territories also contributes to explain the low coverage rate of public distribution companies. Thus, the rapid expansion of the natural gas distribution network in Colombia after the regulatory reforms shows the importance of the establishment of a regulatory structure to push private investment. The Colombian case can be considered a good model for other countries in South America, especially to the natural gas distribution regulation. (author)

    Full Text Available This work aims to analyzing the relationship between the type of financing resources and growth of the manufacturing sectors, grouped according to technological regimes, and to relate this relationship to its degree of adequacy of the sources to the sectoral technological opportunities. Thus, panel data analysis was performed in order to asses the relationship between financial deepening and innovation. We gathered detailed data for each industrial sector, grouped according to its technological regimes, and ran a Granger causality test in panels. Results found report that more innovation-intense sectors, which boosted aggregated economic growth rather steeply, present inadequate financing dynamic to its own growth. Therefore, considering sectors with high technological opportunities and strong innovation persistence, it was observed a bank-based type of financing, whilst the ideal for its growth would be the market-based one. On the other hand, less innovative sectors are found in better situation of financing and better growth conditions. These (non-satisfactory requirements present themselves in (higher lower growth rates and industrial production share.O objetivo do trabalho é analisar a relação entre o tipo de financiamento e o crescimento dos diversos setores da indústria de transformação e ligá-la ao maior ou menor grau de adequação das fontes às oportunidades tecnológicas setoriais.

    The objective of the work is to identify the impacts of the variations in the tariffs of the electricity on the standard of growth of the consumption of electric energy, and the role that these variations had exerted in the allocation of resources by the companies of the sector, in the period 1995-2004. In this period, changes in the habits of consumption of energy due the adopted during the rationing, explain, in part, the reduction of the income-elasticity of the consumption of electric energy, but the contribution of a significant effect-price was important for this reduction. Also are evidenced, in this work, the categories of use and the regions that had more contributed for this effect. For the allocation of resources, from 1998 a decline of the participation of the investments in the sector in the total of investments of the economy is observed, with the companies of the sector presenting differentiated behaviors visibly. The companies of distribution apparently more privileged for the formation of resources, have presented, in the recent years, a declining evolution in its rate of investments when compared with the others segments. Among the determinative factors of the decisions of investment of the companies of distribution, can be mentioned the change in the standard of growth of the consumption and the effect of the evolution of the opportunity cost of the inversions.

    Eugenia uniflora L. (Myrtaceae), known as Brazilian cherry tree, is a fruity tree spread all over Brazil used in popular medicine to treat inflammations, rheumatic pain and fever, as hypoglycemic, diuretic and has been widely used in the cosmetics industry. The present study discusses the chemical composition, the antinociceptive and hypothermic profile of the essential oil of pitangueira leaves. The chemical composition was evaluated by GC-MS and the main constituent of the oil was characterized, after isolation, as a mixture of atractylone (1) and 3-furanoeudesmene (2). The essential oil, its pentane fraction and the isolated mixture of sesquiterpenes (1 and 2), given orally, significantly inhibited the acetic acid-induced abdominal constrictions, increased the latency time in hot plate test and showed a hypothermic effect. The results suggest that the responsible for the antinociceptive and hypothermic effect were the isolated furanosesquiterpenes. These findings provided additional pharmacological information and may contribute for the use of Brazilian cherry tree as a phytomedicine.

    Electricity sector in addition to being a public utility, requires a substantial investment, explore natural resources and the basis of all production chains and consumption of our society. In conclusion, the econometric model used to study the investment to 2010 by Eletrobras meets a correlation acceptable. So a well dependence exists between power and investment in the projects selected. The lack of sophistication and low level of development in credit derivatives financial systems in Brazil, both as a healthy situation of the accounts and balance sheets, due to bitter experience in past crises are allowing a better resistance now.

    This work aims analyze the constraints to the introduction of LNG in the Brazilian energy matrix. Therefore, considers the current regulatory framework and the investments recently made by PETROBRAS to acquire LNG in the international market in order to supply power plants in the country. In order to assess the current status of the LNG plants in the electricity sector, factors are analyzed in terms of the natural gas industry and electric power industry, such as: storage, LNG contracts, operating dispatch, LNG plants pricing and operational flexibility. Despite the increase in LNG international trade and the prospect of using this product in Brazil, there are some challenges for the effective use of LNG plants by Brazilian electric sector. Some of the challenges are the need to review the methodology of calculating the cost benefit of LNG power plants. Another important challenge is to examine the use of underground storage and its influence in the operating dispatch of LNG plants. (author)

Based on these premises, the authors developed a new type of insulating fluid based on Brazilian vegetable oils never used before for this purpose. This product is competitive with similar and patented products developed from canola and soya vegetable oils. Recently a new patent related with the process for the production of this fluid was submitted to the World Industrial Property Organization - WIPO. (author)

  20. A COMPARATIVE ANALYSIS OF CERTIFICATION SCHEMES IN THE BRAZILIAN FRUIT SECTOR

    Directory of Open Access Journals (Sweden)

    ANDRÉA CRISTINA DÖRR

    2009-01-01

    Full Text Available Certification has become increasingly relevant as a marketing signal for agribusiness especially in the fruit sector over the past few years. Substantial parts of many value chains are by now certified by standards as GlobalGAP, Fair Trade, Integrated Fruit Production and Organic. At the same time, in developed countries, particularly in the European Union and the United States, demand for higher levels of food safety has led to the implementation of certification programs that address more types of safety-related attributes and impose stricter standards. Certification systems play an important role in any market that is burdened with a high degree of information asymmetry and quality uncertainty. Thus, producers and exporters of fresh fruit and vegetables from developing countries like Brazil are increasingly required to demonstrate the safety and traceability of their produce up to the consumption stage. The comparative analysis of the four certification schemes which exist in the fruit sector in Brazil has shown that GlobalGAP and the Integrated Fruit Production (PIF are similar certification schemes. However, they differ with respect to the number of requirements and their distribution over various stages (e.g. production, post-harvesting. Contrary to PIF and GlobalGAP, Fairtrade certification concentrates on producers’ organizations and cooperatives where small-scale farmers belong to and not on individual farmers. In addition, a lot of attention is paid to the labour and environmental conditions, besides the guarantee of a minimum price for farmers. With respect to organic certification, the requirements are not directed to a particular product or crop and their level of compliance is not indicated. Major emphasis is put on the production system. Organic and Fairtrade certification do not have an own book keeping for records.

    We studied the response of the ionosphere (F-region) in the Brazilian sector during extreme space weather event of 17 March 2015 using a large network of 102 GPS-TEC stations. It is observed that the Vertical Total Electron Content (VTEC) was severely disturbed during the storm main and recovery phases. A wavelike oscillation with three peaks was observed in the TEC diurnal variation from equator to low latitudes during the storm main phase on 17th and 18th March, 2015. The latitudinal extent of the wavelike oscillation peaks decreased from the beginning of main phase towards the recovery phase. The first peak extended from beyond 0S to 30S, the second occurred from 6S to 25S, whereas the third diurnal peaks was confined from 13S to 25S. In addition, a strong negative phase in VTEC variations was observed during the recovery phase on March 18-19, 2015. This ionospheric negative phase was stronger at low-latitudes than in the equatorial region. Also, two latitudinal chains of GPS-TEC stations from equatorial region to low latitudes in the East and West Brazilian sectors are used to investigate the storm time behavior of the Equatorial Ionization Anomaly (EIA) in the East and West Brazilian sectors. We observed an anomalous behavior in EIA caused by the wavelike oscillations during the storm main phase on 17 March, and suppression of the EIA, resulting from the negative phase in VTEC, in the storm recovery phase.

    The main purpose of this paper is to study the response of the ionospheric F-region using GPS-TEC measurements at equatorial and low latitude regions over the Brazilian sector during an sudden stratospheric warming (SSW) event in the year 2006. In this work, we present vertical total electron content (VTEC) and phase fluctuations derived from GPS network in Brazil. The continuous wavelet transform (CWT) was employed to check the periodicities of the ∆VTEC during the SSW event. The results show a strong decrease in VTEC and ∆VTEC values in the afternoon over low latitudes from DOY 05-39 (during the SSW event) mainly after the second SSW temperature peak. The ionospheric ∆VTEC pattern over Brazilian sector shows diurnal and semidiurnal oscillations during the 2006 SSW event. In addition, for the first time, variations in ∆VTEC (low latitude stations) with periods of about 02-08 day have been reported during an SSW event. Using GPS stations located in the Brazilian sector, it is reported for the first time that equatorial ionospheric irregularities were not suppressed by the SSW event.

    2015-09-01

    Full Text Available In Brazil, the increase in vehicle sales has created various challenges for the fuel market. One major challenge is to make the trip to the gas station a more pleasant activity for customers. In this context, the use of RFID (radio- -frequency identification is an alternative for seeking a competitive advantage through loyalty and personalized services for gas station customers. This article proposes a structure for using RFID in the fuel retail sector. The first part of this article discusses the concepts of RFID technology, the National System for Automatic Vehicle Identification (SINIAV, and relationship marketing and customer loyalty. The subsequent sections contain the proposed structure and the feasibility of adopting this technology. Finally, it was concluded that costs, the absence of international standards, and little knowledge of the technology still impede greater use by companies. Major concerns were seen regarding data privacy. The popularization of this technology may help reduce implementation costs and favor larger-scale adoption of the structure proposed in this study.

    The present study presents a calculation of the environmental costs associated with the atmospheric pollution from a brazilian oil refinery and its analysis (the name of this oil refinery is confidential, for this reason it will not be mentioned). The calculation of the costs was based on a study of north-american researchers, about the environmental costs of five main atmospheric pollutants: particulate matter, sulphur oxides, nitrogen oxides, volatile organic compounds (VOC's) and carbon monoxide. The original American study offers an statistical analysis of several other American studies about environmental costs of atmospheric pollution, that present maximum, medium and minimum costs. Based on these values, the total environmental costs of the atmospheric pollution from the brazilian oil refinery were calculated, considering a fifty year operational time for the facility. The internalization of the atmospheric pollution environmental costs by the refiners is aligned with the world tendency of enforcement of the environmental limitations faced by the oil refining sector, and therefore, the adoption of a pro-active attitude is recommended by the present study.

    2012-11-01

    Full Text Available The aim in this study is to analyze the current stage of conceptual convergence between Brazilian accounting standards applied to the public sector (NBCTSP and the International Public Sector Accounting Standard (IPSAS. The complexity and range of transactions between public or private sector entities, as a result of market internationalization, demand continuous and dynamic assessment of the events that promote quantitative or qualitative equity changes. For this evaluation process, observing accounting principles and standards is important to guarantee, among other information characteristics, understandability and comparability, thus reducing costs for investors and users in general, in view of the barriers raised by diverse languages, cultures, tax and economic policies. For convergence analysis, the standards’ contents were subject to a comparative study, based on a descriptive analysis, with a view to verifying the existing adherence between Brazilian and international standards applied to the public sector. The results found highlight that different aspects still have to be discussed with a view to an actual convergence with the international standards; the current convergence is partial. The high-quality conceptual exposure of the NBCPSPs is observed though, while the contents of the IPSAS are more focused on operating procedures

    Due to the broad impact of legislation limiting greenhouse gas emissions and the increasing public awareness concerning the environment, the oil industry has been currently incorporating climate change considerations in its corporate strategy. However, compliance in the carbon constrained economy does not merely represent a cost issue; it also represents an opportunity. Projects developed under the Clean Development Mechanism (CDM) in particular represent an incentive both for companies and governments to invest in emission reduction projects in developing countries and earn carbon credits, while promoting sustainable development. The oil industry is characterized by a high emission reduction potential and is able to deliver to the market an amount of credits which is by far higher than the amount that most projects developers are able to offer. However some critical issues, such as the current interpretation of the additionally concept, may represent a barrier for the full utilization of such mechanism, particularly regarding petroleum-sector projects, thus reducing the benefits the CDM can actually produce. Considering that a very large number of CDM projects may be needed for the implementation of a successful climate policy, the engagement of the oil industry on the Kyoto mechanisms is very important and auspicial.

This space weather event was studied using a large network of 110 GPS stations. It has been noticed that the Total Electron Content (TEC) was severely disturbed during the geomagnetic storm main and recovery phases. A wavelike oscillation with three peaks is observed from equator to low latitudes during the storm main phase on 17th and 18th March, 2015. Using a latitudinal chain of 8 GPS stations from equatorial region to low latitudes the storm time behavior of the Equatorial Ionization Anomaly (EIA) is investigated. It was noticed that the wavelike oscillation peak latitudinal extent decreases from the beginning of main phase to the recovery phase. The first maximum extends beyond from 2oS to 20oS, the second one from 8oS to 18oS and the third one from 13oS to 17oS. In addition, a strong negative phase in TEC variations is observed during the recovery phase on March 18, 2015. This negative phase is found to be stronger at low-latitude compared to the equatorial region. An anomalous behavior of EIA caused by the wavelike oscillations is observed during the main phase on March 17, 2015. Also, due to the strong negative phase in TEC resulted in strong EIA suppression on March 18, 2015.

    Full Text Available The oils obtained from native palm fruits are considered new sources of high added value phytochemicals, making it necessary to know the composition of the less studied species in order to evaluate their economic potential. The objective of this study is to identify and quantify the arotenoids in palm fruit oils from the Brazilian Amazon: bacaba (Oenocarpus bacaba, buriti (Mauritia flexuosa, inajá (Maximiliana maripa, pupunha (Bactris gasipaes and tucumã (Astrocaryum vulgare, by means of liquid phase extraction and HPLC-UV-vis. analysis. The results showed an extremely variable carotenoid content, from 13 mg·kg−1 in bacaba oil to more than 1000 mg·kg−1 in the tucumã one. The oils obtained from buriti, pupunha and tucumã displayed high concentrations of ß-carotene, corresponding to fruits with the series ß, ß dominant metabolism. Upon analyzing the carotenoid profile in bacaba oil for the first time, an extraordinary dominance of the ß, ε pathway was observed, proving them to be oils with high lutein and α-carotene contents. Although the ß, ß pathway dominates in inajá oil, the exclusive and high lycopene content implies that LCY-E is barely active in these fruits, in contrast to what has been evidenced so far. It is therefore of the utmost importance to characterize these new potential sources of carotenoids.Los aceites obtenidos a partir de frutos de palmeras nativas son considerados nuevas fuentes de fitoquímicos con alto valor añadido siendo necesario conocer la composición de las especies menos exploradas para evaluar su potencial económico. El objetivo de este estudio es identificar y cuantificar los carotenoides en aceites defrutos de palmeras provenientes de la Amazonia Brasileña: bacaba (Oenocarpus bacaba, uriti (Mauritia flexuosa, inajá (Maximiliana maripa, pupunha (Bactris gasipaes y tucumã (Astrocaryum vulgare, mediante extracción líquido:líquido y análisis por HPLC UV-vis.

    The antifungal activity of essential oil (EO) from the Brazilian epazote (Chenopodium ambrosioides L.) was evaluated by the poison food assay at concentrations of 0.3%, 0.1%, and 0.05% with eight postharvest deteriorating fungi (Aspergillus flavus, Aspergillus glaucus, Aspergillus niger, Aspergillus ochraceous, Colletotrichum gloesporioides, Colletotrichum musae, Fusarium oxysporum, and Fusarium semitectum). EO components were tentatively identified by Kováts retention indices (RIs) using gas chromatography and gas chromatography combined with mass spectrometry (GC-MS). Growth of all fungi was completely inhibited at 0.3% concentration, and by 90% to 100% at 0.1% concentration. The following 13 tentatively identified compounds (relative percent) accounted for 90.4% of the total volatile oil: alpha-terpinene (0.9), p-cymene (2.0), benzyl alcohol (0.3), p-cresol (0.3), p-mentha-1,3,8-triene (0.2), p-cimen-8-ol (0.6), alpha-terpineol (0.5), (Z)-ascaridole (61.4), piperitone (0.9), carvacrol (3.9), (E)-ascaridole (18.6), (E)-piperitol acetate (0.5), and (Z)-carvyl acetate (0.3). Autobiographic thin layer chromatography of the EO to separate the principal fungitoxic fraction yielded only one fraction that completely inhibited the growth of all test fungi at a concentration of 0.1%. This fraction was characterized by RIs and GC-MS presenting a composition (%) of p-cymene (25.4), (Z)-ascaridole (44.4), and (E)-ascaridole (30.2). The results suggest ascaridoles were the principal fungitoxic components of the EO.

    This paper analyzes the macroeconomic impacts of the investments in the oil and gas upstream, which took place after the reform of the Brazilian oil industry. The reason why I chose to analyze such a period of time was the institutional change which took place in the Brazilian oil industry after the Brazilian Parliament approved Law n. 9.478 in 1997. The law represented the new regulation of the activities related to the oil industry in Brazil. Since then, there has been a very large amount of capital spending in the oil and gas upstream, not only by PETROBRAS, the state-owned oil company, but also by the oil companies which entered the Brazilian oil industry after it was opened to foreign and private upstream investments. This paper analyses the economic impacts of these upstream investments by PETROBRAS and by the new players in Brazil, addressing the impacts of these investments on the generation of aggregate value and yield and the economic activity of other industries. This paper is dedicated, in its entirety, to Prof. Carmen Alveal, whose knowledge, support, encouragement and friendship were, for me, the most important of all, professionally and morally. (author)

    Full Text Available Conflict can be functional or dysfunctional to the organization’s performance. This study focused on the relationship between conflict approaches implemented by the project manager based on project team member’s perception on the effectiveness of the project manager in managing project’s conflict. Questionnaires were modified from Barker et al. (1988 to measure conflict management approaches and outcomes of managing project conflict. Data were gathered from 57 respondents who worked in the Engineering, Procurement, and Construction (EPC contractors serving the upstream sector of the Oil and Gas industry in Indonesia. By using Pearson correlation, result of this study indicated that project managers were perceived to be effective in managing project conflict when implementing cooperative and confi rmative approaches, but ineffective when combining competitive and avoidance approaches. Further research should investigate correlation between cultural dimensions with conflict approaches and outcomes of managing conflict.

    The sinking of the Prestige oil tanker on 18 November 2002 off the coast of Galicia, Spain, had important economic, environmental and social ramifications. The aim of this paper is to carry out an initial analysis of the costs related to a halt in fishing activities in Galicia between November 2002 and December 2003. This involves three different steps: an assessment of the cost of the preventative and palliative measures introduced by Spanish public administrations (compensation for affected fishermen and shellfish fisherman); an indirect evaluation of the implications of the disaster (via a study of data on production); and a direct appraisal of the economic impact of the event (reduction in income), using questionnaires completed by a representative sample of fishermen and shellfish fisherman. The results obtained from these three methods of estimating losses are compatible. By December 2003, losses to the Galician fishing sector stood at an estimated EUR 76 million.

    Most studies of Brazilian red propolis have explored the composition and biological properties of its ethanolic extracts. In this work, we chemically extracted and characterized the essential oil of Brazilian red propolis (EOP) and assessed its adjuvant, antiparasitic and cytotoxic activities. The chemical composition of EOP was analyzed using gas chromatography with mass spectrometry (GC-MS). EOP was tested for in vitro activity against Trichomonas vaginalis (ATCC 30236 isolate); trophozoites were treated with different concentrations of EOP (ranging from 25 to 500 μg/mL) in order to establish the MIC and IC50 values. A cytotoxicity assay was performed in CHO-K1 cells submitted to different EOP concentrations. BALB/c mice were used to test the adjuvant effect of EOP. The animals were divided in 3 groups and inoculated as follows: 0.4 ng/kg BW EOP (G1); 50 μg of rCP40 protein (G2); or a combination of 0.4 ng/kg BW EOP and 50 μg of rCP40 (G3). Total IgG, IgG1 and IgG2a levels were assessed by ELISA. The major constituent compounds of EOP were methyl eugenol (13.1%), (E)-β-farnesene (2.50%), and δ-amorphene (2.3%). Exposure to EOP inhibited the growth of T. vaginalis, with an IC50 value of 100 μg/mL of EOP. An EOP concentration of 500 μg/mL was able to kill 100% of the T. vaginalis trophozoites. The EOP kinetic growth curve showed a 36% decrease in trophozoite growth after a 12 h exposure to 500 μg/mL of EOP, while complete parasite death was induced at 24 h. With regard to CHO-K1 cells, the CC50 was 266 μg/mL, and 92% cytotoxicity was observed after exposure to 500 μg/mL of EOP. Otherwise, a concentration of 200 μg/mL of EOP was able to reduce parasite proliferation by 70% and was not cytotoxic to CHO-K1 cells. As an adjuvant, a synergistic effect was observed when EOP was combined with the rCP40 protein (G3) in comparison to the administration of each component alone (G1 and G2), resulting in higher concentrations of IgG, IgG1 and IgG2a. EOP is

    The regulation of the law no 9.985, of July 18, 2000, by the decree no 4.340, of August 22, 2002, awake the productive sector to the imposition to the entrepreneur that must destine the amount of at least 0,5% of the total costs foreseen for the hole undertaking implementation, to implement or maintain environmental conservation units. The most of the environmental agencies have been applied 0,5%. The IBAMA uses a methodology to establish the impact level and the range between 0,5% and 5% to define the environmental compensation percentage and is questionable. Then, until now, this legal requirement have been applied in a heterogeneous form to the environmental licensing. The various applied criterions, the huge subjectivity in the impact level assessment, and the influence of this requirement in the licensing schedule, associate to the oil and gas sector project costs point to a relevant impact in the feasibility of the oil and gas sector projects. Based in the percentages that IBAMA had established for the oil and gas sector was esteemed some costs destined to the environmental compensation. The law implementation without inhibition of investments in the country depends on the involved sectors articulation. (author)

    This work is related to a PETROBRAS patent, which defines an alternative technology for maintenance of valves, which are frequently used in the Oil and Gas segment. Until the development of this device, there were no reliable alternatives for the maintenance available at the Brazilian market, thus these valves had to be sent abroad to be repaired. Normally, the maintenance becomes impracticable, due to the high cost and long periods required to accomplish the whole process (send/repair/return). These drawbacks were a decisive impulse to the development of research process, which resulted in the equipment presented here. The Brazilian device for lapidating large diameter metal seated plug valves, that ensures the tightness reliability of these equipment, is being successfully used at PETROBRAS refineries. (author)

    Full Text Available The mosquito Aedes aegypti L. (Diptera: Culicidae is the major vector of dengue and chikungunya fever. The lack of effective therapies and vaccines for these diseases highlights the need for alternative strategies to control the spread of virus. Therefore, this study investigated the larvicidal potential of essential oils from common plant species obtained from the Chapada das Mesas National Park, Brazil, against third instar A. aegypti larvae. The chemical composition of these oils was determined by gas chromatography coupled to mass spectrometry. The essential oils of Eugenia piauhiensis Vellaff., Myrcia erythroxylon O. Berg, Psidium myrsinites DC., and Siparuna camporum (Tul. A. DC. were observed to be mainly composed of sesquiterpene hydrocarbons. The essential oil of Lippia gracilis Schauer was composed of oxygenated monoterpenes. Four of the five tested oils were effective against the A. aegypti larvae, with the lethal concentration (LC50 ranging from 230 to 292 mg/L after 24 h of exposure. Overall, this work demonstrated the possibility of developing larvicidal products against A. aegypti by using essential oils from the flora of the Brazilian Legal Amazon. This in turn demonstrates the potential of using natural resources for the control of disease vectors.

    The current environmental problems caused by human activity has been gaining attention in society, i.e., as it has influenced in the growth and development of the global economic. The availability of energy resources is central point to economic development and the generation of energy is responsible for a significant portion of the emissions causing the greenhouse effect nowadays. The Brazil, a developing country, still has a large number of people without access to electricity, which affects the quality of life of individuals. In this context, it should think in the sustainable economic development, so the alternative energy sources emerge as an option for power generation. Can highlight biomass as a source in the Brazilian scenario by its wide availability and variety. Therefore, the objective of this work is to estimate the economic viability of the decentralized generation of electricity based on the use of biomass from dende oil in small communities in the Brazilian Northeast considering the environmental costs involved for the source in question. The methodology is based on economic concepts and economic evaluation of environmental resources. The biomass from dende oil was adopted in this work by its characteristics and availability in the studied region. The results show that the generation of energy by biomass from dende oil, it will contribute significantly to the sustainable development of the region, already that it will bring gains environmental, social and financial to society.

    Full Text Available This paper explores the literature to identify common occupational injuries, diseases, and psychological wellbeing on oil rigs as well as the negative environmental impacts of the upstream oil and gas sector. It ends by making recommendations for effective health, safety, and environmental (HSE management. Review of the literature showed that contusion (bruise, cuts, and laceration are the commonest occupational injuries that workers on the oil rig suffer and that the injuries mostly affect the hand and finger, leg, and eyes of the offshore workers. These injuries were found to be caused mostly by direct stroke, jamming and overstrain. Similarly, accidental poisoning, musculoskeletal disorders, respiratory disorders and diseases of the digestive system were also documented as the commonest occupational diseases among offshore workers. The literature also shows that working offshore is associated with poorer psychological wellbeing or health; this is to say that offshore workers tend to experience higher levels of stress, burnout, anxiety, depression, low job satisfaction (particularly with the environmental conditions associated with their work, and sleep disorders. Finally, the literature review indicated that land-use problems, air pollution, acid rain, climate change, habitat disruption, environmental degradation, oil spills and leakages are some of environmental impacts of upstream oil production. This review was concluded by recommending some measures for the management of the HSE hazards associated with the oil and gas sector.

    The Brazilian power industry has undergone fundamental institutional changes in order to introduce competition in generation segment by allowing more flexibility to the electricity trading arrangements since mid 90. These reforms were aimed at increasing economic efficiency and both cost and energy price reduction. The restructuring process requested a highly complex legal framework in order to: ensure the necessary investments for the expansion of power infrastructure; stimulate the participation of private capital; and guarantee power supply adequacy at desired safety and reliability levels. The electricity rationing, occurred in 2001, was a result of: lack of investments, growing demand and supply vulnerability to adverse hydrological shocks. As a consequence, the Brazilian Government initiated a wide debate concerning the loopholes in the implanted model as well as the improvements needed to be adopted. The refinement of the electricity trading arrangements is an important aspect of the electric sector model revitalization. It resulted in the implantation of energy auctions aiming at increasing transactions transparency as well as establishing a long run energy price market reference and promoting market efficiency and competition. This paper analyses the implementation of energy auctions as a mechanism for trading power purchase agreements in the long term. It also discusses the Brazilian power industry restructuring process, in the face of the distribution utilities' obligation to purchase power for their captive customers. (author)

    Rousselle, Adam

    Russia's energy sector has changed dramatically over the past three decades and this study examines this change within the oil, gas, and nuclear sectors. Having inherited a state capitalist system after the fall of the Soviet Union, Russia's bureaucracy now presides over an incredibly rich and deeply problematic energy economy. At its core, this is a study on institutionalized corruption and the behavior of corrupt elites. More specifically, it examines whether Russia can succeed within this context and what this may teach us on the nature of corrupt states and institutions.

    The restructuring of the Brazilian Electric Sector has modified the rules for purchase and sale of energy, resulting in the creation of the Wholesale Energy Market. In this new context, the decision of the exposure level to the spot market price and the purchase of energy through bilateral contracts becomes so much a strategic variable for consumers or dealers, as for hydro and thermal generators. This work presents a methodology for planning of energy commercialization envisaging purchase and sale energy opportunities provided by the new Regulatory Framework of the Brazilian Electric Sector.

    Through a retrospective analysis of Mexico's oil history, this work examines the privatization processes that occurred in the petrochemical sector, from the abolishment of the government's monopoly, Petroleos Mexicanos (PEMEX) during the 1980s, until the restructuring and open liberalization in the early 1990s, focusing on the areas incorporated to production processes, particularly along the Gulf coast. As a result of the industrial policies and regional development strategies promoted by the government from the sixties, oriented towards strengthening production in areas with the highest potential, attractive business investment areas were developed. These included southern Tamaulipas, a strategic region where a number of industrial factors facilitated access to raw materials at competitive prices, as well as their processing and distribution to local and international markets, all of these within a single location. The strategic nature of the petrochemical location and production have made southern Tamaulipas a key factor for the territorial shaping and industrial development linked to the behavior of transnational companies that, seeking comparative advantages, have relocated parts of their production capacity in this region.

    The use by Petrobras of Canada's RADARSAT-1 earth observation satellite imaging system to determine the characteristics of the developing environmental disaster when the world's largest oil rig afloat, owned by Petrobras, was sinking of the Brazilian coast following a series of three explosions which seriously damaged the rig. RADARSAT-1 was pressed into service to determine the fate of the oil slick in terms of where it was heading and how soon it would get there, information that is vital to directing clean-up efforts to minimize the damage. RADARSAT-1 was also involved in responding to a tanker oil spill in January 2001 that threatened the Galapagos Islands off the coast of Ecuador. PEMEX, the Mexican state oil company also uses RADARSAT-1 satellite imagery to monitor its nearly 400 marine oil operations in the Gulf of Mexico. RADARSAT-1, launched in 1995 by the Canadian Space Agency, is well known for its reliability, regularity and rapidity. It is equipped with microwave sensors, which can be relied on to produce usable imagery 96 to 97 per cent of the time. It can acquire imagery day or night under any atmospheric conditions through its ability to penetrate darkness, cloud, rain or haze. This is crucial when tracking oil slicks in the ocean where clouds and haze are common, especially near or in the equatorial zones. RADARSAT-1 works by transmitting microwave energy, bouncing it off the earth's surface and back to the satellite. The returning signals are received and stored by the satellite as data. Oil slicks as small as 100 metres long can be detected from space by RADARSAT-1.

    This paper is based on the Brazilian electric sector to outline parallels for introduction of hydrogen as energetic vector in Brazilian matrix. For this purpose it was achieved an analysis of regulation theory, of electric sector reorganization, the new model of energy trade and the NOS role. In face of this analysis, hydrogen regulation may be established through a mix of four models: tariff model by return tax; tariff by marginal cost; regulation by performance and price cap. This new industrial sector should start vertical and with its maturity become non vertical as electric sector after its reorganization. Regarding the market, advanced purchase of hydrogen should be established enabling the reduction of incertitude in trade as well as reduction of implantation costs. NOS should pursue electric energy generation from hydrogen as this may carry impacts in transmission networks as well as in distribution network depending on how hydrogen was generated, whether in large scale or for local consumption supply.

    In most areas of the South Atlantic, exploration in deep-water has just begun. Geological data suggest that similar tectonic-stratigraphic evolution, organic-rich facies and oil types occurs across the South Atlantic petroleum provinces, allowing the application of a unified model for hydrocarbon provenance in counterpart basins. Such similarities, when interpreted in a palaeographic context, can help reveal details of unexplored petroleum systems. This paper, based in an integrated multidisciplinary approach and using technologies ranging from remote sensing to molecular geochemistry, suggests the Amazonas estuary area, as one of the most promising oil/gas-prone provinces to find giant oil and gas accumulations in the Brazilian continental margin. Throughout the tectonic-stratigraphic framework, regional facies variations of Upper Cretaceous and Tertiary source rocks are consistent with a marine carbonate and marine deltaic model for source rock deposition. The origin of the hydrocarbons, in the area, is related to Upper Cretaceous anoxic global events (Cenomanian to Turonian), and a huge fluvial marine deltaic complex that was formed during the Miocene. The Benue Through and Niger delta oil province are comparable petroleum system analogues. (author)

    Even as the US debates an economy-wide CO{sub 2} cap-and-trade policy the transportation sector remains a significant oil security and climate change concern. Transportation alone consumes the majority of the US's imported oil and produces a third of total US Greenhouse-Gas (GHG) emissions. This study examines different sector-specific policy scenarios for reducing GHG emissions and oil consumption in the US transportation sector under economy-wide CO{sub 2} prices. The 2009 version of the Energy Information Administration's (EIA) National Energy Modeling System (NEMS), a general equilibrium model of US energy markets, enables quantitative estimates of the impact of economy-wide CO{sub 2} prices and various transportation-specific policy options. We analyze fuel taxes, continued increases in fuel economy standards, and purchase tax credits for new vehicle purchases, as well as the impacts of combining these policies. All policy scenarios modeled fail to meet the Obama administration's goal of reducing GHG emissions 14% below 2005 levels by 2020. Purchase tax credits are expensive and ineffective at reducing emissions, while the largest reductions in GHG emissions result from increasing the cost of driving, thereby damping growth in vehicle miles traveled.

    Rwabizambuga, Alexis

    The thesis contributes to the perspective on the role of stakeholder engagement in negotiating corporate social responsibility (CSR) policies and practices in developing country context. It critically examines the role of societal pressures as drivers of Shell's CSR agenda, and explores the forms of relationships existing between Shell and its stakeholders in Nigeria, as the company implements its CSR programme, both in the light of its strategic business objectives and of its social responsibilities and environmental liabilities. Furthermore, it examines the role of government in the oil MNCs' CSR agenda, and explores the conditions under which the government, in its dual role as business partner and as state authority, promotes CSR policies and practices in Nigeria. Shell's CSR policies and practices in Nigeria were examined under the theoretical lenses of the resource-based view perspective extended to notions of legitimacy and the licence to operate. Additionally, the stakeholder engagement perspective was applied as the theoretical framework for examining Shell's stakeholder engagement, and the role of the company's stakeholders in negotiating its current CSR policies and practices in Nigeria. Data collection was undertaken during field research in Nigeria. The evidence presented is drawn from individual interviews with corporate executives at Shell Nigeria, Shell International, several stakeholders in the Nigerian oil sector, and from an online survey conducted in 2005 on Shell Nigeria's stakeholders. Both quantitative and qualitative methods were used throughout the analysis presented in the thesis. The research findings suggest that the relationship between the firm's pursuit of the social licence to operate through CSR initiatives and stakeholder engagement is more complex than assumed. It adds to the understanding of the dynamics of a MNC's stakeholder engagement in the local context. It highlights the various interdependencies that develop between

    This paper describes the goods and services supply oil segment, as different than the oil companies segment itself. It points to the transformations in the goods and services supply segment from the 1980s until now. At that time with low international oil prices, the oil companies induced the goods and services firms to assume a major role in development of technology. Inside the country here, the goods and services segment had high local content performance but it was associated to low technology intensity or to branches of large multinational firms installed in the Brazilian market. The paper points the French approaching on this same oil segment and its applicability to the Brazilian case, giving one example of financial R and D resources for supporting such a target. Otherwise than in France some specific obstacles can be found here in that development purpose. As alternative some others scenarios were finally explored in the paper for further suggestions for institutional approaching in this Brazilian industrial oil segment. (author)

    This study draws attention to the fact that most of the discussions and studies related to the restructuring of electricity industry in Brazil, almost exclusively address the technological and institutional aspects involved in the question, when competitive strategies and management models to be followed by power companies are essential to ensure the consolidation of new design of the institutional industry in the daily operation of business. The proposition is that the evaluation of competitive strategies and management models can be a working tool for the State, in addition to offer to the electric power companies administrators an initial map or check list for planning and operation of its business, in the institutional model that is being implemented for the Brazilian electric sector.

    2008-11-15

    This thesis analyses the dynamics of risk management in the regulated contracting environment of the Brazilian electrical sector. As in the new model the distribution utilities are obliged to ensure energy contracting to supply their whole markets, these companies became exposed to volume risks related to the demand uncertainties. So the new model following similar directives from the first phase developed management tools to mitigate the new risks mentioned above. As in a well structured market it is expected that the risks should be evenly shared or that risk management tools should be provided for all, this work intended to analyze the dynamics of the designed mechanisms and their impacts over the regulated market. In this work the risks of the electricity markets are studied and the management tools devised for the Brazilian market are identified. Finally for understanding the dynamics a thorough analysis of the auctions, of the mechanism for compensation of surplus and deficits and tariffs are carried on. The results show that the management tools were regularly employed by distribution companies, but the risks were merely transferred to the captive customers leading to distortions and asymmetries that conflict with the basis that guided the second phase of the reform. The work proposes remedial actions to mitigate the observed impacts and to provide risk management tools to the captive customer. (author)

    Several techniques have been used to minimize the problems caused by the wax deposition, and the continuous addition of polymeric inhibitors is considered an attractive technological alternative. The addition of copolymers like polyacrylates, polymethacrylates or poly(ethylene-co-vinyl acetate) (EVA) permit to inhibit the deposition phenomenon; nonetheless, this effect is specific, i.e. similar copolymers present different performance depending on their physical-chemical properties in solution. In this work, the influence of the EVA vinyl acetate content on the viscosity and the pour point of a Brazilian crude oil were evaluated. A correlation between both results was also obtained. The phase behavior and the solubility parameter of EVA copolymers, with different vinyl acetate contents, were investigated in various solvents together with an evaluation of the efficiency of these copolymers as pour point depressants for two different samples of crude oil. EVA copolymers containing 20, 30, 40 and 80 wt.% of vinyl acetate were used and tests with the crude oil were carried out using 50, 500, 1000 and 5000 ppm of EVA as additive. The results obtained from viscosity measurements showed that only below the temperature at which wax crystals start forming did the copolymer exhibit a strong influence in the reduction of oil viscosity, at an optimum concentration. The pour point results revealed EVA 30 to be the most efficient. The results obtained from both experiments showed that the viscosity and the pour point behaviors do not show good correlation. Not only the solubility parameter and the vinyl acetate content, but also the molecular weight and polydispersity have an important influence on both phase behavior and pour point depression. Furthermore, it was confirmed that the additive must present a reduced solubility at a temperature close to the crude oil cloud point. This, however, is not the only factor that determines the efficiency of the additive as paraffin

    Multilamellar liposomes incorporating essential oil of Brazilian cherry (Eugenia uniflora L.) leaves were produced by dry film hydration. Gas chromatography demonstrated the compounds found in the essential oil were effectively incorporated in the aqueous dispersions of liposomes. Differential scanning calorimetry analyses revealed the incorporation of the essential oil did not cause phase separation in the membrane structure; the gel-liquid crystalline transition temperature (main transition) remained the same despite the higher heterogeneity indicated by the transition peak broadening. Different cryoprotectors (sucrose and trehalose) were added to the liposomal formulations to be tested in their ability to protect the liposomal structure during the lyophilization. The morphological aspect of the lyophilized powders analysed by scanning electron microscopy showed significant differences among the samples with and without cryoprotectors. Fourier-transform infrared spectroscopy indicated the cryoprotectors interacted effectively with the polar heads of phospholipids in the bilayer. In terms of water absorption, trehalose was identified as a much more effective protector agent against it than sucrose. The cryoprotectors showed different degrees of effectiveness of preservation of the liposomal structure when the rehydration assays of lyophilized liposomes were carried out, as particle size measurements indicated a moderate process of fusion when the formulations with sucrose were rehydrated.

    Canada offers one of the most generous, broadly applicable business tax incentives for eligible research and development projects in the world. The scientific research and experimental development (SR and ED) program is administered by the Canada Revenue Agency and is the single largest federal program, providing over 3 billion dollars in tax assistance to Canadian businesses in 2006. The development of in-situ oil sands recovery technologies such as steam assisted gravity drainage and other techniques have been research-intensive undertakings that have historically benefited from the SR and ED program, many of which are now commercial available technologies. The SR and ED program definition, eligible activities, eligible expenditures, and benefits were described in this paper. These benefits include the ability to deduct qualifying expenditures currently or to defer them indefinitely, as well as investment tax credits that reduce taxes payable on a dollar for dollar basis. Research and development in the heavy oil and oil sands industries was also discussed with reference to platforms for research and development; areas of potential SR and ED. It was concluded that the SR and ED program is a vital source of financing to many Canadian corporations, and could offer significant assistance to companies in the heavy oil and oil sands sector by returning 20-35 per cent of the expenditures back at the federal level as a tax credit. 5 refs.

    This report discussed health and wellness trends in the oil and gas sector in relation to employee assistance program (EAP) data. The data were derived from oil and gas client organizations across Canada for 2008, and represented a population base of 14,685 employees. The data demonstrated that EAP utilization in the petroleum industry increased by approximately 5 per cent from 2006 to 2008. The sector's utilization was 34 per cent higher than the Canadian norm in 2006, and 40 per cent higher than in 2007 and 2008. Females used the EAP to a greater extent than males. A higher proportion of the spouses of workers accessed EAP than the national norm. Employees accessed EAP for assistance with work-life issues; family support services; and substance abuse interventions. Weight management and dietary consultations in relation to disease control were also of concern within the sector. A 66 per cent increase in childcare issues was noted, as well as a 148 per cent increase in eldercare issues, and a 112 per cent increase in addiction issues. The findings indicated that the EAP is being effectively communicated as a relevant and accessible tool. As the industry continues to develop in remote regions, new services and resources will be required to retain existing workforces and attract new employees. Prevention-focused training and services and program for at-risk groups are needed to ensure that employee health and productivity is maintained. 1 tab., 4 figs.

    Virgin olive oil is a key ingredient of the renowned Mediterranean diet. In this context, the main objective of this study was to estimate and decompose productivity change for Protected Designations of Origin (PDOs) in the Spanish virgin olive oil sector for the period 2008-2013. To this end, we introduced a Luenberger-type indicator based on a specific weighted additive model in Data Envelopment Analysis (DEA), which, in contrast to previous studies, captured all sources of inefficiency and avoided infeasibilities. Regarding the results, we found a reduction in productivity, in average terms, in the first periods analyzed (-0.12 and -1.65), followed by an improvement (0.79 and 0.54), that in the last period analyzed (2012-2013), however, returned to adverse figures (-0.47). In Spain, where foreign competition is weak, the most productive PDOs were those with an important number of oil mills and packaging/marketing companies such as “Montes de Toledo” and “Siurana”; productivity changes were mainly the consequence of downwards and upwards of the frontier of the technology over time. These changes were explained, to a certain extent, by the evolution of the economic crisis; and the productivity of the sector declined, in general, from 2008 to 2010, improving thereafter except for the last registered period, 2012-2013, where expectations for market recovery exceeded actual sales.

    Full Text Available Brazil is presently going through its worse electricity supply crisis in fifty years. This happens after seven year efforts of market-oriented reforms, and inevitably raises the issue of whether the design and rhythm of the reform have been correct. The roots of the present crisis lie in a long period of underinvestment dating from the eighties; sector reforms were aimed at correcting this situation, but have been unsuccessful thus far. This article discusses the causes of this failure and attempts a way out of the present problems. The present crisis requires an emergency answer, but also a long term policy. I argue that such a policy must be based upon the acknowledgement that electricity demand in Brazil will tend to grow fast for the foreseeable future and that sector reform must be based upon dynamic rather than static efficiency. Furthermore, the large Brazilian hydropower system requires special treatment if we are to have investment in hydro and in thermal plants.

    Full Text Available The antimicrobial activity of copaiba oils was tested against Gram-positive and Gram-negative bacteria, yeast, and dermatophytes. Oils obtained from Copaifera martii, Copaifera officinalis, and Copaifera reticulata (collected in the state of Acre were active against Gram-positive species (Staphylococcus aureus, methicillin-resistant S. aureus, Staphylococcus epidermidis, Bacillus subtilis, and Enterococcus faecalis with minimum inhibitory concentrations ranging from 31.3-62.5 µg/ml. The oils showed bactericidal activity, decreasing the viability of these Gram-positive bacteria within 3 h. Moderate activity was observed against dermatophyte fungi (Trichophyton rubrum and Microsporum canis. The oils showed no activity against Gram-negative bacteria and yeast. Scannning electron microscopy of S. aureus treated with resin oil from C. martii revealed lysis of the bacteria, causing cellular agglomerates. Transmission electron microscopy revealed disruption and damage to the cell wall, resulting in the release of cytoplasmic compounds, alterations in morphology, and a decrease in cell volume, indicating that copaiba oil may affect the cell wall.

    The present study aimed to evaluate the in vitro antimicrobial action of Origanum vulgare, Origanum majorana, Mentha piperita and Rosmarinus officinalis on Pythium insidiosum oomycete zoospores. The antimicrobial activity evaluation was performed by the broth microdilution method according to CSLI M38-A2 documentation adapted to phytopharmaceuticals. Twenty-two P. insidiosum isolates were evaluated, and the minimum inhibitory concentration was determined at 100% growth inhibition. All P. insidiosum isolates evaluated showed a minimum inhibitory concentration ranging from 0.05 to 1.75 mg/mL when O. vulgare oil was used and from 0.11 to 3.5 mg/mL for O. majorana, M. piperita and R. officinalis oils. The results obtained indicate that the essential oils tested showed antimicrobial activity on P. insidiosum, with O. vulgare essential oil showing the best performance. These findings emphasize the potential use of plant essential oils as control agents in P. insidiosum infections; further research, however, is needed so as the in vivo activity of these oils can also be evaluated.

    Full Text Available Palm Oil is a fantastic plant for the people of Riau Province. It can be seen from the rapid development of plantations, in 2001 palm oil plantations covered an area of 1,119,798 ha and in 2010 it increased to 1,925,341 ha with a growth of 36.02%. Palm oil plantation activities brought economic impact on society, both for the people who are directly involved with the activities of plantations and for their surrounding community. To anticipate the rapid development, a model avoiding inequality of income among farmers needs to be designed, especially for self-supporting farmers in a partnership pattern. Institutional model aims to increase the welfare of rural farmers in the form of Palm Oil Based Agroestate (ABK. The concept of Palm oil Based Agroestate collaborates between farmers, cooperatives, and business enterprises. Through the ABK program, farmers will have an opportunity to buy/have shares of the Palm oil Factory (PKS. There are two main business activities of ABK model; first, business activities that build palm oil plantations and factories of the derivative industry; if necessary the settlement of participaing farmers will be established by the developers; second, managing plantations and participating farmers-owned factories as well as market the products carried out by a business enterprise or a cooperative formed by the participant farmers.

    The chemical profile of the essential oils obtained from the leaves and flowers of Hyptis passerina Mart., a rare species of the Brazilian Cerrado, has been determined for the first time. Analyses by GC-MS showed sesquiterpenes as major compounds. {beta}-epi-acorenol (35.7% and 32.8%, respectively from leaf and flower essential oils), was isolated and identified by 1D and 2D NMR. The flower-derived oil presented a higher concentration of hydrocarbon and oxygenated monoterpenes, while the leaf-oil was richer in diterpenes. The global odour impressions of both oils were given by direct analysis and GC-MS-O and were characterized as herbaceous with tea notes, and green, cooked and woody impressions for leaf-oil; herbaceous, with spicy, woody and minty notes for flower-oil. {beta}-epi-acorenol, spathulenol, {beta}-caryophyllene, and caryophyllene oxide were relevant for the odour-activity of both oils, as well as minor constituents, such as linalool. The antimicrobial activity was investigated by means of agar diffusion disc method and contact bioautography, against Gram-positive and negative bacteria and yeast. Both oils presented to be bioactive against the tested microorganisms with significant inhibition level. (author)

    One of the biggest challenges for PETROBRAS is to find alternative crude oils to produce base oil and wax in its refinery. Duque de Caxias refinery has been using imported crude oil for 31 years living with constants threats to continuity because of the Persian Gulf conflicts. If we analyze the profitability of this business, we can verify that the lubes complex had contributed for the profitability by about 41,9% in 2002, even using imported crude oil. So, if we can incorporate a national crude oil in the actual refinery scheme, we would produce besides strategic gains better profitability for the base oil and wax unit. This paper describes a series of tests performed in the pilot plant, in which we produced base oils and wax using a mixture of imported crude with Brazilian crude oil. The base oils produced were classified as Group I with lower aromatic, Sulphur and basic Nitrogen content. Another great advantage of this alternative is that the light fractions obtained from distillation step can be used as feed to make fuels of better quality, due to the lower sulphur content, thus also reducing the environmental impact.

    The electricity sector in addition to being a public utility, requires a substantial investment, explore natural resources and the basis of all production chains and consumption of our society. The dynamics of this sector goes beyond the individual performance of energy companies and will also interfere in matters of political, economic, social and environmental development of nations. The lack of sophistication and low level of development in credit derivatives financial systems in Brazil, both as a healthy situation of the accounts and balance sheets, the fruit of bitter experience in past crises are allowing a better resistance to weather the current crisis. But it is an important trading partner of Brazil, through various business financial economic crises that is affecting the U.S. economy and the world has also affected the economy of our country, but with less intensity. The econometric model used to study the investment to be initiated in 2010 by ELETROBRAS meets a correlation acceptable; this demonstrates that a well dependence exists between power and investment to the projects to be implemented.

    Full Text Available Objective – Analyze the reactions of the stock market to M&A announcements, i.e. find out if there was value creation and consequently maximization of shareholder wealth or whether there was value destruction and consequently a decrease in the wealth of the shareholders of the acquiring companies in the short term. Design/methodology/approach – Event study – Quantitative Method Findings – It can neither be affirmed that the acquisitions had a significant impact on value creation for purchasers and banks, nor can it be denied. Given the lack of preponderance of either positive or negative returns, the transactions may have been perceived in different manners. Practical implications – The results may be explained by the fact that the synergies that resulted from the M&A processes in the banking sector only helped consolidating major market players and consequently reduced competitiveness in that sector. The negative abnormal returns of M&A processes are due to the monopolistic market competition structure (Tabak, Fazio & Cajueiro, 2012. Contributions – Event Study with robust errors

    This work studies the own capital cost of the Brazilian electric sector, by using three methodologies: Comparable Accounting Results (CAR), using historical values for measurement, Discounted Cash Flow (DCF) and the CAPM, elaborated from expected values.The obtained results by using the CAR method indicated that the Brazilian electric power sector is not receiving remuneration according to the real maintenance and expansion necessities. Based on this observation, it was considered appropriated to discard the CAR method in the proposed methodology, therefore using the simply average of the CAPM e DCF models. By using the simply average of the models presents the advantage of capturing specific characteristics of each model, and to dilute effects of eventual extreme values.

    Full Text Available Industrial production of biodiesel fuel in Egypt by the transesterification of vegetable oils is being faced with the problem of feedstock shortage. Egypt imports annually about 90% of its needs as edible oils for human consumption. The production of biodiesel by direct esterification of fatty acids that can be obtained from the oil and soap industrial sector in huge quantities each year (around 16 thousand tons may be a proper solution to this problem. According to results of a previous study [1], the biodiesel produced following this approach and using methyl alcohol was quite efficient as an alternative fuel for diesel engines. However, the process should be economically feasible for application on an industrial scale. The present study assessed the economic feasibility of biodiesel production by direct fatty acid esterification. Complete process simulation was first carried out using the process simulation software, Aspen HYSYS V7.0. The process was then designed comprising four main steps being esterification, solvent recovery, catalyst removal and water removal. The main processing units include the reactor, distillation column, heat exchangers, pumps and separators. Assuming that the rate of fatty acids esterified was 2 ton/h, all process units required have been sized. Total capital investment, total manufacturing cost and return on investment were all estimated. The latter was found to be 117.1% which means that the production process is quite economically feasible.

    The Petroleum Industry Human Resource Committee (PIHRC) commissioned this study in December 2002 to develop a profile of the labour demand and supply for the upstream production phase of the offshore oil and gas industry. Interviews with representatives from more than 45 countries in the offshore oil and gas sector in Newfoundland and Labrador were conducted. In addition, the results of a mail survey forwarded to an additional 42 companies were included along with a review of secondary labour market research. More than 340 positions were identified in the production phase in the study. Of these, approximately 80 were identified as difficult to recruit for a variety of reasons including: insufficient experience in the oil industry; occupational shortages; short-term or project employment opportunities; very limited employment opportunities and limited occupational supply; lack of specific occupational training programs; and additional projects possibly leading to occupational shortages. The study provided valuable input concerning future labour market and human resource planning and career counselling on the 340 positions previously identified. 10 tabs.

    In the present study, we document daytime total electron content (TEC) disturbances associated with medium-scale traveling ionospheric disturbances (MSTIDs), on few chosen geomagnetically quiet days over Southern Hemisphere of Brazilian longitude sector. These disturbances are derived from TEC data obtained using Global Navigation Satellite System (GNSS) receiver networks. From the keograms and cross-correlation maps, the TEC disturbances are identified as the MSTIDs that are propagating equatorward-eastward, having most of their average wavelengths longer in latitude than in longitude direction. These are the important outcomes of the present study which suggest that the daytime MSTIDs over Southern Hemisphere are similar to their counterparts in the Northern Hemisphere. Another important outcome is that the occurrence characteristics of these MSTIDs and that of atmospheric gravity wave (AGW) activities in the thermosphere are found to be similar on day-to-day basis. This suggests a possible connection between them, confirming the widely accepted AGW forcing mechanism for the generation of these daytime MSTIDs. The source of this AGW is investigated using the Geostationary Operational Environmental Satellite system (GOES) and Constellation Observing System for Meteorology, Ionosphere, and Climate satellite data. Finally, we provided evidences that AGWs are generated by convection activities from the tropospheric region.

    Essential oils from species of the genus Hyptis are well-known for their significant biological properties, including antimicrobial and acaricidal activities. The essential oil from the aerial parts of H. crenata was obtained by hydrodistillation; bomeol (17.8%), 1,8-cineol (15.6%) and p-cimene (7.9%) were characterized by GC-MS as its major constituents. The essential oil was evaluated in vitro for its antimicrobial activities against six fungal and five bacterial strains, by measuring the respective MICs, MFCs and MBCs, using broth microdilution methods. The strongest bactericidal activities were shown against Staphylococcus aureus and Enterococcus faecalis, while the strongest fungicidal activities were against Cryptococcus neoformans, Candida glabrata and Candida tropicalis. The oil was also assessed for its anti-tick properties and, at a concentration of 2.5%, it significantly inhibited in vivo oviposition of engorged females of the cattle tick Rhipicephalus (Boophilus) microplus, using the adult immersion test., with an effectiveness of 94.4%.

    Full Text Available Crude oil samples with high- and low-water content from two offshore platforms (PA and PB in Campos Basin, Brazil, were assessed for bacterial communities by 16S rRNA gene-based clone libraries. RDP Classifier was used to analyze a total of 156 clones within four libraries obtained from two platforms. The clone sequences were mainly affiliated with Gammaproteobacteria (78.2% of the total clones; however, clones associated with Betaproteobacteria (10.9%, Alphaproteobacteria (9%, and Firmicutes (1.9% were also identified. Pseudomonadaceae was the most common family affiliated with these clone sequences. The sequences were further analyzed by MOTHUR, yielding 81 operational taxonomic units (OTUs grouped at 97% stringency. Richness estimators also calculated by MOTHUR indicated that oil samples with high-water content were the most diverse. Comparison of bacterial communities present in these four samples using LIBSHUFF and Principal Component Analysis (PCA indicated that the water content significantly influenced the community structure only of crude oil obtained from PA. Differences between PA and PB libraries were observed, suggesting the importance of the oil field as a driver of community composition in this habitat.

    Several types of crude oil have a large amount of wax, which can crystallize, at low temperatures, reducing the oil flow. Polymeric additives are able to prevent the wax deposition and to reduce the pour point of the oil, what improves the oil flow at low temperatures. Some acrylic polymers containing C{sub 12+} pendant groups are found in the literature as efficient additives for crude oils. Nevertheless, this type of polymer has not yet been used in Brazilian crude oils. In this work, octadecyl acrylate (ODA) was synthesized by transe esterification of methyl acrylate (MA). By using these monomers, several copolymers of MA-ODA (containing different compositions and different molecular weights) were obtained by solution copolymerization. The performance of the copolymers as pour point depressants was verified by using a crude oil from Bacia de Campos, RJ, Brazil. Increasing the ODA content in the copolymer, its efficiency increases and the best results were obtained with the copolymer MA:ODA (36:64). The crude oil containing this copolymer as additive presented a pour point reduction of 26 deg C but the lower the copolymer molecular weight the worse the polymeric additive performance. (author)

    An outbreak of serogroup C meningococcal disease (MD) that involved employees from an oil refinery occurred in Paulínia, from March to June 2010, and spread to the community of Cosmópolis, both situated in São Paulo State, Brazil. The aim of this study was to describe the epidemiological and laboratory aspects, and the control measures that were implemented. Descriptive and molecular epidemiological analysis was used to define the extent of the outbreak and the common risk factors among outbreak related cases. Vaccination initiative targeted the employees from the oil refinery and the community-based individuals. A total of six outbreak-related cases of MD in the oil refinery and 12 cases in the city of Cosmópolis, São Paulo State occurred in a three-month period. All 18 MD cases were confirmed as serogroup C either by culture, real time polymerase chain reaction (RT-PCR), or counterimmunoelectrophoresis (CIE). The meningococcal isolates (n=15) had the phenotype C:23:P1.14-6 and showed close genetic relationship by pulsed field gel electrophoresis (PFGE). Multilocus sequence typing (MLST) characterization showed that the clones were ST 3780, ST-103 complex. The isolates were susceptible to the antibiotics tested. Vaccination was administered to 15,848 persons at the oil refinery and 18,571 persons of the community. The molecular characterization of the Neisseria meningitidis (N. meningitidis) strains, and the efficient investigation and the prompt measures implemented were essential for controlling the disease in the region.

    Full Text Available Biological, and particularly antimicrobial, activities have been demonstrated for the essential oil of propolis samples worlwide, yet their mutagenic effects remain unknown. To correlate antimicrobial effects with mutagenic risks, the present study evaluated the antifungal and antibacterial activities of the essential oil obtained from brown propolis collected from the Cerrado biome in Midwest Brazil (EOP, testing it against nine pathogenic microorganisms. Evaluation of mutagenic potential was based on the somatic mutation and recombination test (SMART performed on wing cells of standard (ST and high-bioactivation (HB crosses of Drosophila melanogaster. EOP was extracted by hydrodistillation, and sesquiterpenes were characterized by GC–MS as its major constituents. The crude oil proved active against Cryptococcus neoformans and Enterococcus faecalis, as did two of its major constituents, spathulenol and (E-nerolidol – the latter being also active against Staphylococcus aureus – isolated using chromatographic procedures. No significant increase in the number of somatic mutations was observed in the offspring of ST or HB crosses – the latter exhibiting enhanced levels of metabolizing enzymes of the cytochrome P450 type – treated with 0.05%, 0.1%, and 0.2% EOP. These findings revealed no mutagenic activity of EOP, even when tested against the HB strain, and demonstrated that its antimicrobial activities are not associated with DNA damage induction (investigated with SMART, suggesting the potential of EOP as a natural preservative.

    groups in the Brazilian clothing industry describing their characteristics to compare with defined variables in the study. Data of 510 enterprises from 2006 were used. The efficiency scores were calculated using Data Envelopment Analysis, cluster analysis was used to identify groups, and Discriminant Analysis was used to validate the clusters. The results showed high degree of inefficiency, and the average deficiency of efficiency results showed the possibility to increasing of 98.17% in outputs keeping the same level of inputs. It was possible to identify three strategic groups significantly validated by the discriminant analysis, and the group composed basically of large enterprises showed better performance than the one composed basically by micro and small enterprises. The presence of different strategic groups, especially with regards to size, shows that the domestic industry has internal barriers inherent in the peculiarities of the higher resource availability of large companies than that of small companies. Therefore, these results agree with those reported in the literature concerning the suggestion that micro and small businesses should focus on other strategies to avoid competition with the economies of scale of large enterprises. In terms of strategic groups, this allows the building of internal barriers of mobility strengthening the competitiveness of the national industry.

    The quantification of greenhouse gases (GHG) emissions represents a critical issue for the future development of agro-food produces. Consumers' behaviour could play an important role in requiring environmental performance as an essential element for food quality. Nowadays, the carbon footprint (CFP) is a tool used worldwide by agro-food industries to communicate environmental information. This paper aims to investigate the role that CFP could have in consumers' choices in three significant agro-food sectors in the Mediterranean area: wine, olive oil and cereals. A critical review about the use of CFP was carried out along the supply chain of these three sectors, in order to identify opportunities for enhancing food quality and environmental sustainability and highlighting how environmental information could influence consumers' preferences. The analysis of the state of the art shows a great variability of the results about GHG emissions referred to agricultural and industrial processes. In many cases, the main environmental criticisms are linked to the agricultural phase, but the other phases of the supply chain could also contribute to the increased CFP. However, despite the wide use of CFP by companies as a communication tool to help consumers' choices in agro-food products, some improvements are needed in order to provide clearer and more understandable information. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Full Text Available The objective of this work was to evaluate the morphological diversity of oil palm seeds and to cluster the accessions according to their morphological characteristics. Forty-one accessions from the oil palm germplasm bank of Embrapa Amazônia Ocidental were evaluated - 18 of Elaeis oleifera and 23 of E. guineensis. The groups were formed based on morphological characteristics, by principal component analysis. In E. oleifera, four groups were formed, tied to their region of origin, but with significant morphological differences between accessions from the same population. For tenera-type E. guineensis seeds, three widely divergent groups were formed, especially as to external parameters, which differentiated them from the other ones. The parameter endocarp thickness stood out in intra- and inter-population differentiation. For dura-type E. guineensis, three groups were formed, with larger seeds and thicker endocarps, which differed from all the other ones. The variability observed for seed characteristics in the analyzed accessions allows the establishment of different groups, to define strategies for genetic improvement.

    This work studies the owner capital cost of the brazilian electric sector, according to three methods: Comparable Accounting Earnings, that uses historical values in its measuring and Discounted Cash Flow (DCF) and the Capital Asset Pricing Model (CAPM), elaborated from the expected values. The obtained results by using the CAE method showed that the Brazilian electric sector has not been rewarded in its real necessity of maintenance and expansion. From this observation, it was considered appropriated not to take this method in the methodology presently proposed, which will be using only the single average of the CAPM and DCF models. The use of the results single average of this model presents the advantage of selecting specific characteristics of each one, and diluting the effects of occasional peak values. The owner capital cost obtained from this work was the average value of 19.73% for the studied period - 1995/2003 (17.12% for 2003), proximate to the obtained result by ANEEL - brazilian agency of electric power - for investments in energy distribution in Brazil, 17.47%, while Minardi and Sanvicente (2003) obtained 36.06% for the owner capital cost of CEMIG in 2002, specifically.

    Full Text Available Para poder formular estrategias y llevar a cabo actuaciones que permitan mejorar la posición competitiva de las cooperativas, es necesario realizar un análisis de las mismas. Las cooperativas agrarias, al igual que el resto de empresas, también están sometidas a cambios y por ello es necesario conocer sus puntos fuertes y débiles con la finalidad de detectar tanto oportunidades como amenazas. Hasta ahora el objetivo principal de las cooperativas ha estado el de la comercialización de los productos. Sin embargo, la nueva situación socioeconómica plantea la necesidad de que dichas entidades asuman nuevos objetivos, tales como la mejora de la calidad y la conservación del medio ambiente, nuevas estrategias de ventas, diversificación de la producción, etc. En el presente artículo se analizan las características generales del sector cooperativo en Cataluña para ver en que grado dicho sector tiene protagonismo en las fases posteriores a la producción.

    Full Text Available Neomitranthes obscura (DC. N. Silveira is an endemic plant of Brazilian Atlantic Forest and widely spread in the sandbanks of “Restinga de Jurubatiba” National Park. It is popularly known by local population as “camboim-de-cachorro” or “cambuí-preto” and recognized by its black ripe fruits. However, specimens with yellow ripe fruits were localized in the “Restinga de Jurubatiba” National Park. The aim of the present study was to evaluate chemical composition of essential oils obtained from leaves and fruits of N. obscura specimens with different fruit color (black and yellow by GC and GC-MS. Essential oils from leaves of specimens with black and yellow fruits indicated a predominance of sesquiterpenes (81.1% and 84.8%, resp.. Meanwhile, essential oil from black fruits presented a predominance of monoterpenes (50.5%, while essential oil from yellow fruits had sesquiterpenes (39.9% as major substances. Despite previous studies about this species, including essential oil extraction, to our knowledge this is the first report on N. obscura fruits with different colors. Our results suggest the occurrence of unless two different varieties for this species.

    Full Text Available The paper demonstrates the role of mineral tax in the overall sum of tax revenues in the budget. Problems of tax computation and payment have been reviewed; taxpayers and taxation basis of the amount of extracted minerals have been clearly defined. Issues of rental content of natural resource taxes are reviewed, as well as problems of right definition of the rental component in the process of mineral tax calculation for liquid and gaseous hydrocarbons.One of important problems in mineral tax calculation is a conflict between two laws – the Subsoil Law and the Tax Code of Russian Federation (26th chapter. There is an ambiguity in the mechanism of calculating amounts of extracted mineral resources – from the positions of the Tax Code and the Subsoil Law. The second problem is in the necessity to amend the mineral tax for oil extraction the same way as it has been done for gas extraction, when characteristics of each field are taken into account.This will provide a basis for correct computation of the natural resource rent for liquid and gaseous hydrocarbons. The paper offers recommendations for Russian authorities on this issue.

    The 2009 L'Aquila seismic sequence activated a complex, about 40 km long, NW-trending and SW-dipping normal fault system, consisting of three main faults arranged in right-lateral en-echelon geometry. While the northern sector of the epicentral area was extensively investigated by oil companies, only a few scattered, poor-quality commercial seismic profiles are available in the central and southern sector. In this study we interpret subsurface commercial data from the northern sector, which is the area where is located the source of the strong Mw5.4 aftershock occurred on the 9th April 2009. Our primary goals are: (1) to define a reliable framework of the upper crust structure, (2) to investigate how the intense aftershock activity, the bulk of which is clustered in the 5-10 km depth range, relates to the Quaternary extensional faults present in the area. The investigated area lies between the western termination of the W-E trending Gran Sasso thrust system to the south, the SW-NE trending Mt. Sibillini thrust front (Ancona-Anzio Line Auctt.) to the north and west, and by the NNW-SSE trending, SW-dipping Mt. Gorzano normal fault to the east. In this area only middle-upper Miocene deposits are exposed (Laga Flysch and underlying Cerrogna Marl), but commercial wells have revealed the presence of a Triassic-Miocene sedimentary succession identical to the well known Umbria-Marche stratigraphic sequence. We have analyzed several confidential seismic reflection profiles, mostly provided by ENI oil company. Seismic lines are tied to two public wells, 5766 m and 2541 m deep. Quality of the reflection imaging is highly variable. A few good quality stack sections contain interpretable signal down to 4.5-5.5 s TWT, corresponding to depths exceeding 10-12 km and thus allowing crustal imaging at seismogenic depths. Key-reflectors for the interpretation correspond to: (1) the top of the Miocene Cerrogna marls, (2) the top of the Upper Albian-Oligocene Scaglia Group, (3) the

  13. A method for calculating a land-use change carbon footprint (LUC-CFP) for agricultural commodities - applications to Brazilian beef and soy, Indonesian palm oil.

    The world's agricultural system has come under increasing scrutiny recently as an important driver of global climate change, creating a demand for indicators that estimate the climatic impacts of agricultural commodities. Such carbon footprints, however, have in most cases excluded emissions from land-use change and the proposed methodologies for including this significant emissions source suffer from different shortcomings. Here, we propose a new methodology for calculating land-use change carbon footprints for agricultural commodities and illustrate this methodology by applying it to three of the most prominent agricultural commodities driving tropical deforestation: Brazilian beef and soybeans, and Indonesian palm oil. We estimate land-use change carbon footprints in 2010 to be 66 tCO2 /t meat (carcass weight) for Brazilian beef, 0.89 tCO2 /t for Brazilian soybeans, and 7.5 tCO2 /t for Indonesian palm oil, using a 10 year amortization period. The main advantage of the proposed methodology is its flexibility: it can be applied in a tiered approach, using detailed data where it is available while still allowing for estimation of footprints for a broad set of countries and agricultural commodities; it can be applied at different scales, estimating both national and subnational footprints; it can be adopted to account both for direct (proximate) and indirect drivers of land-use change. It is argued that with an increasing commercialization and globalization of the drivers of land-use change, the proposed carbon footprint methodology could help leverage the power needed to alter environmentally destructive land-use practices within the global agricultural system by providing a tool for assessing the environmental impacts of production, thereby informing consumers about the impacts of consumption and incentivizing producers to become more environmentally responsible. © 2014 John Wiley & Sons Ltd.

    This article discusses the Brazilian Petroleum Agency (ANP) strategy to boost the competitiveness of Brazil in attracting investments to the energy sector, analyzing it both technically and economically. The Campos basin, with its opportunities in heavy oil and deep water exploration, is used as a case study. Previous literature evaluated the economic potential of oil fields under different hypotheses for cost and price structures, reaching the conclusion that the fiscal regime of Brazil in 2000 was internationally competitive and the oil fields under investigation were attractive. This situation no longer applies. Some of the previous hypotheses are reviewed, using the creaming effect, which models both the diminishing success probabilities of drilling and volume levels as a given sedimentary basin approaches its mature stage of exploration. The main conclusion is that a reduction in the government take, lowering the fraction under ANP's control, would foster exploration and production in mature basins. Therefore, a large number of reserves with relatively small VOR's will become feasible, which are currently unattractive, given the hurdle rates observed by the international oil industry. (author)

    A method is proposed that makes possible determining total and 'thermally stable' vanadium in crude oil without prior separation, and to calculate 'volatile' vanadium by difference. The volatile fraction is believed to be largely vanadyl porphyrine complexes. The method is based on the unsurpassed background correction capability of high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS), which allows pyrolysis temperatures as low as 300 deg. C to be used. The samples were prepared as oil-in-water emulsions, and aqueous standards emulsified in the same way were used for calibration. Total vanadium has been determined using a pyrolysis temperature of 400 deg. C, and 'thermally stable' vanadium using a pyrolysis temperature of 800 deg. C. The content of total vanadium in 12 Brazilian crude oil samples was found to be between less than 0.04 and about 30 mg kg{sup -1}. The volatile fraction was between 5 and 51% of the total content, and there was no correlation between the total and the volatile vanadium content. The limits of detection and quantification were 0.04 and 0.12 mg kg{sup -1} of V in crude oil, respectively, based on a mass of 2 g of oil in 10 mL of emulsion. The precision was better than 4% at the 3 mg kg{sup -1} level and better than 1.5% at the 30 mg kg{sup -1} level of V in crude oil.

    We use Michael Porter`s work from the University of Harvard, about the competitive advantage of nations as a theoretic instrument to analyze the Brazilian oil industry. Introducing the author`s concept of diamond, we try to develop a new understanding of the oil competition. Then, we discuss about the competitive condition of Brazil in the international oil natural gas industry. Porter analyses the domestic condition and the system of relationships among what the calls the determinants of competitive advantage of nations. These determinants are four: the factor condition; the demand condition: the related and supporting industries; and the firms strategy, and the industrial structure and rivalry. Briefly, the Brazilian oil and natural gas industry has a well-developed factor condition. The country has a challenging base of natural resources, high skilled human resources and a large range of oil related technologies. However, the condition of Brazil`soil gas demand is still far from the necessary sophistication to stimulate the national competitiveness. Regarding the related and supporting industries, although Brazil has developed a complex industrial system, with the leadership of PETROBRAS, the major challenge for the country is to improve efficiency and reduce costs. Finally, with the recently approved open-up of the Brazilian oil sector to private investors, it has been created the context where the domestic rivalry between oil companies can provide a dynamic and competitive national environment.

    , a structure was in which competition took place between A and B Band operators. In a second phase, when universalization targets were achieved, foreseen in the new Brazilian telecommunications model, competition between the operators was intensified, with the entrance of D and E Band operators. Given the changes in the market structure of the Brazilian telephony sector, in the period after privatizations, this study aimed to verify if the Brazilian mobile telephony operators were enjoying economies of scale, through the analysis of the polynomial cost function and of cost curves. An applied documentary research was carried out, using the statistical method of least squares with a model for panel data. The estimated results of the cost function for the sector revealed that production based on the number of clients presented growing returns and decreasing production, evidencing the existence of economies of scale in the sector. However, the sector contained an excessive number of companies, given the market's demand for Brazilian mobile telephone companies to enjoy the benefits of scale gains.

    The geochemical characterization of petroleum is an essential task to develop new strategies and technologies when analyzing the commercial potential of crude oils for exploitation. Due to the chemical complexity of these samples, the use of modern analytical techniques along with multivariate exploratory data analysis approaches is an interesting strategy to extract relevant geochemical characteristics about the oils. In this work, important geochemical information obtained from crude oils from different production basins were obtained analyzing the maltene fraction of the oils by comprehensive two-dimensional gas chromatography coupled to quadrupole mass spectrometry (GC×GC-QMS), and performing multiway principal component analysis (MPCA) of the chromatographic data. The results showed that four MPC explained 93.57% of the data variance, expressing mainly the differences on the profiles of the saturated hydrocarbon fraction of the oils (C13-C18 and C19-C30n-alkanes and the pristane/phytane ratio). The MPC1 grouped the samples severely biodegraded oils, while the type of the depositional paleoenvironments of the oils and its oxidation conditions (as well as their thermal maturity) could be inferred analysing others relevant MPC. Additionally, considerations about the source of the oil samples was also possible based on the overall distribution of relevant biomarkers such as the phenanthrene derivatives, tri-, tetra- and pentacyclic terpanes.

    Most palm oil currently available in global markets is sourced from certified large-scale plantations. Comparatively little is sourced from (typically uncertified) smallholders. We argue that sourcing sustainable palm oil should not be determined by commercial certification alone and that the certification process should be revisited. There are so-far unrecognized benefits of sourcing palm oil from smallholders that should be considered if genuine biodiversity conservation is to be a foundation of 'environmentally sustainable' palm oil production. Despite a lack of certification, smallholder production is often more biodiversity-friendly than certified production from large-scale plantations. Sourcing palm oil from smallholders also alleviates poverty among rural farmers, promoting better conservation outcomes. Yet, certification schemes - the current measure of 'sustainability' - are financially accessible only for large-scale plantations that operate as profit-driven monocultures. Industrial palm oil is expanding rapidly in regions with weak environmental laws and enforcement. This warrants the development of an alternative certification scheme for smallholders. Greater attention should be directed to deforestation-free palm oil production in smallholdings, where production is less likely to cause large scale biodiversity loss. These small-scale farmlands in which palm oil is mixed with other crops should be considered by retailers and consumers who are interested in promoting sustainable palm oil production. Simultaneously, plantation companies should be required to make their existing production landscapes more compatible with enhanced biodiversity conservation. Copyright © 2017 Elsevier Ltd.

    In the Brazilian Electric System about 92% of the generated electricity is of hydraulic origin. Today the system is operating practically in the limit of your capacity. Solutions of short time to make possible the expansion of the offer of electricity generation go by the installation of cycle combining thermal using natural gas as fuel. In this dissertation, it was used the real options theory to evaluate generation assets in the Brazilian electricity sector. In Brazil, central operator dispatches a flexible thermal when the electricity spot price is larger than the operation costs. The operation decision is like an European call, where underlying asset is the electricity and the strike price is the operation cost. The value of the capacity is the sum of all decisions to operate the thermal unit, in the remaining life of unit. It was used Monte Carlo Simulation and Dynamic Programming to evaluate this model. The problem is divided in two parts. In the first part, the base case is fixed and evaluated and the expected NPV and project risk are calculated in function of contract level. In the second part, many sensibilities are done in relation to base case. At the end, the value of flexibility is calculated for each contract level. (author)

    The electric sector went through deep changes along these 125 years of electrification of the country, mainly the alternation of their investment bases, hour being private for the most part, state hour. The legal bases of concession and regulation also varied in this period, trying to adapt to the effective model of the time. This work intends to analyze the evolution of the regulatory models of the electric sector, identifying the main changes of paradigms and to compare the efficiency of the models already implanted in the segment, with views to the increment of the offer of energy in the period, molding a critical profile of the best model already adopted in the national electric sector. To compare qualitatively these models requests an analysis of the investment bases a priori in the sector, identifying the contribution of resources has been private or state, following by the government's legal positioning in the sense of being only regulator, or regulator and investor, concluding with an analysis of the electric power offer in the period and the power of self-financing of the companies, in order to assent that the mixed model is the most appropriate model for the sustainable growth of the electric power generation sector in Brazil.

    This study discusses the potential for reducing carbon dioxide (CO2) emissions from energy use by the Brazilian industrial sector in a low-carbon scenario over a horizon until 2030. It evaluates the main mitigation measures, the quantities of this gas avoided and the respective abatement costs. In relation to a benchmark scenario projected for 2030, the reduction of CO2 emissions estimated here can reach 40% by adopting energy efficiency measures, materials recycling, cogeneration, shifting from fossil fuels to renewable or less carbon content sources, and eliminating the use of biomass from deforestation. The set of measures studied here would bring cumulative emissions reductions of nearly 1.5 billion tCO2 over a period of 20 years (2010-2030). This would require huge investments, but the majority of them would have significant economic return and negative abatement costs. However, in the cases there would be low economic attractiveness and higher abatement costs, thus requiring more effective incentives and a collective effort, from both the public and private sectors.

  11. The Rise and Decline of U.S. Private Sector Investments in Energy R&D since the Arab Oil Embargo of 1973

    Energy Technology Data Exchange (ETDEWEB)

    Dooley, James J.

    2010-11-01

    This paper presents two distinct datasets that describe investments in energy research and development (R&D) by the US private sector since the mid1970s, which is when the US government began to systematically collect these data. The first dataset is based upon a broad survey of more than 20,000 firms’ industrial R&D activities. This broad survey of US industry is coordinated by the US National Science Foundation. The second dataset discussed here is a much narrower accounting of the energy R&D activities of the approximately two dozen largest US oil and gas companies conducted by the US Department of Energy’s Energy Information Agency. Even given the large disparity in the breadth and scope of these two surveys of the private sector’s support for energy R&D, both datasets tell the same story in terms of the broad outlines of the private sector’s investments in energy R&D since the mid 1970s. The broad outlines of the US private sector’s support for energy R&D since the mid 1970s is: (1) In the immediate aftermath of the Arab Oil Embargo of 1973, there is a large surge in US private sector investments in energy R&D that peaked in the period between 1980 and 1982 at approximately $3.7 billion to $6.7 billion per year (in inflation adjusted 2010 US dollars) depending upon which survey is used (2) Private sector investments in energy R&D declined from this peak until bottoming out at approximately $1.8 billion to $1 billion per year in 1999; (3) US private sector support for energy R&D has recovered somewhat over the past decade and stands at $2.2 billion to $3.4 billion. Both data sets indicate that the US private sector’s support for energy R&D has been and remains dominated by fossil energy R&D and in particular R&D related to the needs of the oil and gas industry.

    The essential oils from leaves and inflorescences of Lippia origanoides Kunth present aromatic and medicinal potential and have been used to treat several diseases, including melanoma. In Brazil, L. origanoides is commonly found in campo cerrado and cerrado stricto sensu, physiognomies featured mainly by the differential light conditions to which short and medium-sized plants are subjected. Our aim was to investigate the glandular trichome density and the yield and chemical composition of the essential oils in leaves and inflorescences of L. origanoides from campo cerrado and cerrado stricto sensu. For glandular density analysis, leaves and inflorescences were processed according to conventional techniques for scanning electron microscopy. The essential oils of leaves and inflorescences were obtained by hydrodistillation and identified with gas chromatography. Bracts and sepals showed the highest glandular density, followed by petals and leaves. The glandular density in the abaxial leaf surface was higher in individuals from the campo cerrado. In both populations the essential oil yield was higher in inflorescences than in leaves. The chemical composition of the essential oils varied among individuals from different areas and inside a same population. Our results demonstrated the chemical plasticity of L. origanoides suggesting the importance of monitoring its popular use.

    Roads provide the main means of transportation in Brazil. According to data from the Brazilian Department of Infrastructure and Transport, 96.2% of the passenger transportation and 61.8% of the cargo transportation are based on road infrastructure. However, three quarters of the Brazilian roads are in terrible, unsatisfactory or generally inadequate condition. Poor road conditions are responsible for a great number of accidents with severe consequences for the population and the environment. Given the importance of this matter, there is a need to develop an intelligent system for automatic classification of social and environmental sensitivity maps in order to support actions that respond to emergencies and to help in transportation planning, especially considering the heavy movement of hazardous cargoes such as petroleum and its derivates. For this, tools such as Geographic Information System (GIS) allow social-environmental and traffic engineering characterization maps to be analyzed on a unified, geo referenced digital base. This way, administrators can estimate which stretches of the network are more environmentally sensitive and which pose greater risks, and therefore draw inferences on the most socially and environmentally vulnerable. Social and environmental vulnerability data not only help in the classification of the areas which pose the greater risks, but also make it possible to decide on emergency support points, creating a culture of prevention in the area of hazardous cargo transportation. The case study on the state of Rio Grande do Norte provides a measure of the importance of such work. The city of Natal - the state capital - and the Guamare petrochemical facility are interconnected by 180 Km Road, on which more than 100 tanker trucks loaded with diesel and its derivates travel every day. This road is classified as in poor conditions and, according to the Brazilian Roads Police, it is one of the most dangerous. The relevance of this work is to show

Desse modo, o objetivo da presente investigação é analisar a emergência e o desenvolvimento de uma Reforma Sanitária numa formação social capitalista, seus fundamentos e características, discutindo os desafios da práxis. Partindo de quatro tipos de práxis e de mudanças em sociedades - reforma parcial, reforma geral, movimentos políticos revolucionários e revolução social total - defende-se a tese segundo a qual a Reforma Sanitária Brasileira, como fenômeno social e histórico, constitui uma reforma social. O estudo tem como hipótese que a Reforma Sanitária Brasileira, embora proposta como práxis de reforma geral e teorizada para alcançar a revolução do modo de vida, apresentaria como desfecho uma reforma parcial - setorial e institucional. Realizou-se um estudo de caso, a partir de pesquisa documental, em duas conjunturas, tendo como componente descritivo o ciclo idéia-proposta-projeto-movimento-processo e, como componente explanatório, a análise do desenvolvimento da sociedade brasileira, recorrendo ao referencial "gramsciano", particularmente às categorias de revolução passiva e transformismo.

    The African oil industry, (particularly in the deep water offshore fields of the Gulf of Guinea), is symbolic of the new balance of power taking shape in the oil industry between the international companies and the host state on the one hand, and between the petrol companies themselves on the other. In an area rich in potential and which has become highly competitive, the traditional players in the region's oil development sector (Shell, Chevron and TotalFinaElf) which have for so long been sheltered from genuine competition in their respective areas of activity, must now face up to the renewed ambitions of new 'Super Majors' (in particular ExxonMobil), not to mention those of many independent companies seeking to internationalize their business. Several reasons explain this change. Firstly, the main developments are now taking place offshore with deep water drilling, and financial solidity and technological competence have replaced the closeness of political links as key factors of success. In these conditions, the risk of long term marginalization for the medium-sized companies is considerable. Secondly, the need to achieve profitability stressed by the major petrol groups is opening the door to the independents who are operating a niche policy (based on marginal or mature fields which no longer interest the majors). This type of competition tends to promote activity and to open up new countries to exploration and production (in particular Equatorial Guinea). (author)

    The prediction of products properties is a useful tool in the petroleum industry, because it allows the estimation of quality when it is not possible to be determined it in the laboratory. Among existing correlations for properties prediction, the best known are those from the American Petroleum Institute (API), but there are limitations in the use of such models to estimate the properties of Brazilian petroleum products. A study was done to determine new correlations which would adjust to these oils. In this work a statistical treatment was used in a group of samples covering products from oils produced in several regions of Brazil. The results of this study are presented in this work. New correlations are proposed to estimate the aniline point, pour point and cloud point of Brazilian oil products. The data are showed graphically, with the experimental values plotted against the results of both the proposed and the API correlations. The average absolute deviations obtained for these correlations were smaller than those presented by the API equations, for the same data sets. This work helps to improve the quality estimation of Brazilian petroleum products using process simulators. (author)

    Full Text Available In an environment of rapid changes one should seek definitions of what would be the strategic solutions adopted by organizations to ensure a competitive edge. This article is targeted to identify and verify the longevity of potential competitive advantages in Brazil’s mobile telephone sector through the analysis of the strategic actions taken by its operators between 2000 and 2008. Therefore, a two stage qualitative research with exploratory-descriptive features was adopted and carried out. The first stage saw the development of a theoretical framework based on the theory of competitive advantage. In the second step, the impact of strategic actions with the potential to become a competitive advantage in the four major mobile phone companies in the country was analyzed, and the examination of the sustainability of competitive advantages created from those actions was also undertaken. The study concluded that, although being a highly dynamic and competitive sector, there is evidence of the occurrence of a sustainable competitive advantage in the mobile telephone sector in Brazil.

    Recent Brazilian policies have encouraged impoverished communities to participate in the country's growing energy industry. This paper explores the country's attempts to encourage such participation within the oil and gas and biofuels sectors. Our research is based on interviews with industry executives, policymakers, non-governmental organizations and farmers conducted between 2005-2009 in Brazil, an emerging energy leader, yet a country grappling with social exclusion. We propose that some sectors have a propensity to be exclusive due to technological complexity, whereas other sectors, although less complex, tend to economize at the expense of social programs. We conclude with managerial and policy implications.

    Full Text Available Foreign direct investment is new phenomenon to Iraq, a post conflict country with abundance of natural resources. With dominant state-controlled public sector, attracting foreign investment is an added challenge to an economy devastated by years of wars. A qualitative case study was conducted to assess determinants of foreign direct investment in Iraq’s energy sector. Data was collected from interviews with business and government subject matter experts, and a review of publically available documents. Lack of security, political instability, corruption, and inadequate government policies towards foreign direct investment as symptoms found and typically shared by other post-conflict countries. The persistence of violence was not seen as a deterrent; however, foreign direct investment activity in the energy sector was virtually limited to the semi-autonomous region of Kurdistan. Investments were either wholly-owned or joint-venture enterprises. Implications to other post conflict countries, using Kuwait and Nigeria as illustrative examples, are presented and recommendations made.

    The generation expansion-planning problem is a non-linear large-scale optimisation problem, which is even larger when it refers to the Brazilian system, and when one considers the multiple intervening uncertainty sources. To handle the complexity of the problem, decomposition schemes have been used. Usually, such schemes divide the expansion problem into two sub-problems: one related to the construction of new plants (investment sub-problem) and another dealing with the task of operating the system (operation sub-problem). This thesis proposes a genetic algorithm to solve the investment sub-problem. Initially, an analysis of the state of the art on the generation expansion planning and the field of the genetic algorithms are presented. Then follows a practical application of the proposed algorithm in a model of generation expansion planning under uncertainty. Finally, the results obtained in two case studies are presented and analysed. These results indicate that the proposed genetic algorithm is an effective alternative to the solution of the investment sub-problem. (author)

    Full Text Available Resumen: El sector del petróleo y gas es un sector económico estratégico con repercusiones a escala global. Sin embargo, una de las principales limitaciones de esta industria radica en las características de las regiones en las que opera, ya que a menudo se trata de zonas geográficas de elevada importancia bioclimática, zonas con poblaciones indígenas o sectores rurales sumidos en la pobreza. Esto ha generado que los stakeholders presten cada vez más atención a las implicaciones sociales, naturales y económicas de las actividades del sector del petróleo y gas. Así las cosas, teniendo en cuenta que los países latinoamericanos cuentan con las mayores reservas convencionales mundiales de petróleo, el presente artículo tiene como objetivo cuantificar la información voluntaria sobre sostenibilidad que divulgan las empresas petroleras y gasíferas que operan en Latinoamérica.   Abstract:  The oil and gas sector is a strategic area of the economy with global repercussions. This industry faces a major handicap, namely the characteristics of the regions in which it operates, which are often geographic areas of great bioclimatic importance, or inhabited by indigenous populations, or comprised of very low income rural sectors. In response, stakeholders are paying ever greater attention to the social, natural and economic consequences of oil and gas sector activities. Taking into consideration that Latin American countries possess the largest conventional oil reserves in the world, this paper aims to quantify the sustainability information disclosed voluntarily by oil and gas companies operating in Latin America.

    The purpose of this research was to develop practical care procedures to help maintain the protective quality of flame resistant workwear laundered by workers in the field. Based on observed field conditions, experiments were conducted that simulated domestic laundry procedures. The first experiment involved two flame resistant (FR) fabrics, contaminated or not contaminated with oil. Independent variables also included detergent type and laundry pre-treatment. Other laundry parameters were controlled. Results indicated that it is easier to maintain the FR performance of the FR-treated blend than it is for the aramid fabric. It is hypothesized that energy generated by initial ignition of oil on the specimens triggers the FR mechanism of the treatment, which in turn inhibits further combustion. A second experiment using larger specimens and a domestic washing machine also supported the hypothesized mechanism.

    In the oilfield sector, a thermal method named in-situ combustion (ISC) is used as an enhanced recovery method. ISC consists of the injection of gas into the reservoir, a combustion front is created producing heat which reduces the oil viscosity. For this method to be successful, understanding of the thermal and kinetic parameters involved is required; the aim of this paper is to evaluate those parameters for different crude oils. Experiments were conducted using accelerating rate calorimetry on Brazilian heavy oil samples under a heat-wait-seek-mode. Results showed that accelerating rate calorimetry is efficient in resolving the three main regions of reaction of the oil and that between 200 degree C and 300 degree C oxygen addition reactions are dominant while bond scission reactions dominate from 350 degree C. This study demonstrated that accelerating rate calorimetry is an efficient method to determine thermal and kinetic parameters of oxidation reaction of heavy oil.

    This analysis is developed within a broad context that is characterized by efficient use of electricity in a region environmentally and socially diverse. It considers that energy efficiency is required throughout the process from generation to power consumption, resulting in an interdisciplinary view of the problems reported here. With this guiding principle, the article analyzes the crises of electricity and makes a historical account of some important legal provisions to the environmental and social problems of the state. It assumes that the applicability of the Electric Sector Legislation, in Amazon, becomes inadequate, once in the depopulated endless area, the solutions do not come, simply, by modern technologies where either the traditional ones have place. Studies carried out by the Federal University of Amazonas bring subsidies to the analysis, which aims to create a forum for discussion about the practice of treating as equal parts of deep diversity.

    This study seeks to quantify the reductions that can be achieved in CO{sub 2} emissions from burning fuels by Brazilian industries in a long-term low-carbon scenario. We model two horizons, for 2030 and 2050, and also for each sector quantify the abatement costs and other economic parameters and the main technological options applicable, namely: enhanced energy efficiency; replacement of fossil fuels with renewable energy sources or ones with a smaller carbon footprint; elimination of the use of biomass from deforestation; and cogeneration. In the low-carbon scenario for 2030, a reduction of CO{sub 2} emissions of some 40% can be achieved that year, or approximately 1.5 billion tCO{sub 2} over the period from 2010 to 2030. These reductions would require substantial investments, but in most cases they would be economically attractive, with low or negative abatement costs. For 2050, we modeled a more aggressive scenario, through faster implementation of some specific measures and introduction of new technologies. Despite the possibility of favorable economic results, companies have been reluctant to adopt several of the mitigation measures examined. We discuss some policies, including granting incentives, to overcome the barriers and difficulties to wider adoption of mitigation measures. (author)

Altogether, it were analyzed nine categories of environmental impacts for both processes (abiotic depletion (kg Sb eq, land use (m2a, global warming (kg CO2 eq, ozone layer depletion (kg CFC-11 eq, human toxicity (kg 1,4-DB eq, freshwater ecotoxicity (kg 1,4-DB eq, terrestrial ecotoxicity (kg 1,4-DB eq, acidification (kg SO2 eq and eutrophication (kg PO43- eq. The results of evaluation of environmental impacts show that the biodiesel production process from soybean oil presents major environmental damage in seven categories of analyzed impacts (destruction of abiotic resources, destruction of the ozone layer, human toxicity, freshwater ecotoxicity, terrestrial ecotoxicity, acidification and eutrophication. The production process of biodiesel from tallow presents major environmental damage in two categories of impacts analyzed (land use and global warming. However, the results show that the absolute values of environmental damage caused by impacts of the production process using beef tallow are much more aggressive.

    Environmental building recommendations aimed towards new environmental policies and management-changing decisions which as example demonstrated in consideration of the problems of Canadian oil sands operators. For the implementation of the circular economic strategy, we use an in-depth analysis of reported environmental after-consequence on all stages of the production process. The study addressed the promotion of innovative solutions for greenhouse gas emission, waste mitigation, and risk of falling in oil prices for operators of oil sands with creating market opportunities. They include the addition of microalgae biomass in tailings ponds for improvement of the microbial balance for the water speedily cleaning, recycling, and reusing with mitigation of GHG emissions. The use of food scraps for the nutrition of microalgae will reduce greenhouse gas emission minimally, on 0.33 MtCO2eq for Alberta and 2.63 MtCO2eq/year for Canada. Microalgae-derived biofuel can reduce this emission for Alberta on 11.9-17.9 MtCO2eq and for Canada on 71-106 MtCO2eq/year, and the manufacturing of other products will adsorb up to 135.6 MtCO2 and produce 99.2 MtO2. The development of the Live Conserve Industry and principal step from non-efficient protection of the environment to its cultivation in a large scale with mitigation of GHG emission and waste as well as generating of O2 and value-added products by the use of microalgae opens an important shift towards a new design and building of a biological system.

    The purpose of this paper is to analyze the methodology for power consumption projection presented in the Ten-year (2007-2016) Plan of Power Expansion (PDEE 2007/2016) and to propose some questions for discussion. Indeed, bearing in mind the progress achieved in the recent past with respect to the resumption of long term planning in the Brazilian electric power sector, it is pertinent to promote a discussion about the possible limitations of the expansion methodology proposed in PDEE. In short, it is believed that, starting from such a discussion, it could be possible to contribute towards the aim of making the planning process of the Brazilian electric power sector expansion more transparent, more consistent and more participative, consequently bringing a greater convergence of the expectations of the agents of the sector. The main questions raised in this paper about the PDEE's methodology are with respect to the absence of sufficient detail about the interactive adjustment of the several models used to project the consumption, as well as to the lack of information about the models themselves. The general conclusion of this paper is that, in order that the PDEE meets its objective of providing correct signals to all the agents, it is necessary to include more incisively the sector's specialists and the private agents in the methodological discussions, so that no important doubts will remain about the various projections. In our understanding, the success of such an enterprise will depend not only on the disposition of the agents, but on the greater detail and depth that should be previously given to the questions raised in this paper. It is certainly a significant challenge, of a high complexity but of an even higher importance to the electric power sector and to the Brazilian economy. (author)

  12. The influence of supplier assessment in the termination of oil and gas exploitation and production contracts in Brazil

    Full Text Available The supplier performance assessment literature shows that the prior identification of contracts considered unsatisfactory may prove crucial to the maintenance of a company, especially in sectors with high operational and environmental risk and significant investments, such as the oil and gas exploitation sector. Although considered important, contract termination has been little studied in the Brazilian oil segment, due to the small number of firms operating in the sector and restricted access to information from these companies. This article aims to reduce this gap by analyzing what service assessment criteria most influence contract terminations in the Brazilian sector of oil and gas exploitation and production. Therefore, the assessments of service contracts terminated between 1/1/2006 and 12/31/2014 by a business unit active in oil and gas exploitation and production located in Brazil were analyzed using logit regressions. In the resulting database, 273 contracts were found that include all specialized services in the activity, totaling 19,613 ratings. The results indicate that the Term and Logistics criteria reveal the greatest influence on contract cancelations of the sector activities. In addition, by segregating the analysis by specialty, it was found that different specialties have different requirements and therefore different contractual arrangements. These results empirically corroborate the theoretical discussions in the literature about the importance of compliance with contractual obligations, especially with regard to the negotiated deadlines.

    This paper describes a series of pilot plant tests made at PETROBRAS Research Centre, considering hydrotreatment and solvent dewaxing steps, to produce group II and group III lube base oils from Baiano Light crude feeds (Brazilian crude). RLAM Refinery has been using Baiano light crude to produce group I base oils by conventional route and in the pilot plant studies, two types of process scheme were tested. In the first one, an industrial run was performed at RLAM Refinery, including distillation, dewaxing and extraction and the light raffinate was used as a feed for a hydrotreatment pilot plant, followed by a distillation to remove the front ends. In the second scheme, another industrial run was performed, including distillation and dewaxing steps and the medium dewaxed oil was used as a charge for a hydrotreatment followed by distillation and dewaxing pilot plant tests. Products of excellent quality were obtained. Due to their high viscosity indexes (from 96 to 126), low contaminants levels (sulfur < 5 ppm and nitrogen < 5 ppm) and low aromatic content (CA < 2 %), the lube base oils produced are therefore classified as group II and group III. The main advantages of this route are related to the base oils quality improvements with low investment and more flexibility in terms of crude source. (author)

    This article objectified to analyze the influence of the appearance of great reserves of oil in the layer daily pay-salt and its consequences in the Brazilian agribusiness, raising the possibility of occurrence of the 'dutch illness' and the impacts in the production of ethanol, that before the daily pay-salt, were one of the great products of Brazil. In case that the expectation is confirmed, Brazil could be between the six countries that possess the biggest reserves of the world. The results point with respect to a little steady scene, case the country if it becomes a great exporter of crude oil. One of the great problems for the agribusiness will be related with the fall of the exportations of the agricultural and industrialized products, when the country will start to import more, in view of the cambial valuation, for the fortified currency. It will be able to have an impact of the displacement of the workmanship's agriculture for the sector of services, and the valuation of the wages, reducing the edge of profit of the agricultural producers. This movement will tend to increase the unemployment tax of the country throughout the time. It is defined one public politics for fuel sector.

    Biopolymers can be used where petrochemical plastics have applications with short life. The excellent degradation of starch and its low cost make it an alternative for obtaining biodegradable plastics. To obtain thermoplastic starch (TPS) is necessary mechanical shake, high temperature and plasticizers. In this work, TPS were produced using three different vegetable oils from Brazilian's cerrado as plasticizers: buriti, macauba or pequi. Materials are also produced with montmorillonite (MMT). All the materials were analyzed by scanning electronic microscopy (SEM) and X-ray diffraction (XRD). The starch micrographs revealed irregular delaminate with a predominance of starch and 'holes' for the oils. In nanocomposites the clusters of clay are dispersed without a defined standard. It was understood that the plasticizers and processing completely changed the structure of starch causing a decrease in their crystallinity degree. Almost all nanocomposites presented exfoliate structure, only one presented intercalated structure. (author)

  17. Middle-Skilled Workforce Needs in a Changing Oil and Gas Industry: the Role of Flexibility. As the Oil Industry continues to shed jobs due to the global downturn in oil prices, one of the most vulnerable sectors to job loss are the middle-skilled workers such as the technicians and drill operators. We present options and ideas to mitigate the problem.

    Middle-skilled workers are those whose jobs require considerable skill but not an advanced degree. Nationwide, one-third of the projected job growth for 2010-2020 will require middle-skilled workers. The educational paths to these jobs include career and technical education (CTE), certificates and associate's degrees from community colleges, apprenticeship programs, and training provided by employers. In the oil industry, the demand is expected to about 150,000 jobs. In environmental restoration and monitoring, there will be a need for at least 15,000 middle-skilled workers. Examples of the types of jobs include geological and petroleum technicians, derrick and drill operators, and pump system and refinery operators for the oil and gas sector. For the environmental restoration and monitoring sector, the types of jobs include environmental science technicians, and forest (and coastal) conservation technicians and workers. However, all of these numbers will be influenced by the growth and contraction of the regional or national economy that is not uncommon in the private sector. Over the past year, for example, the oil and gas industry has shed approximately 75,000 jobs (out of a workforce of 600,000) here in the United States, due almost exclusively to the drop of oil prices globally. A disproportionate number of the lost jobs were among the middle-skilled workforce. Meanwhile, the recent settlements stemming from the Deepwater Horizon oil spill are expected to create a surge of environmental restoration activity in the Gulf of Mexico region that has the potential to create thousands of new jobs over the next decade and beyond. Consequently, there is a need to develop education, training and apprenticeship programs that will help develop flexibility and complementary skill sets among middle-skilled workers that could help reduce the impacts of economic downturns and meet the needs of newly expanding sectors such as the environmental restoration field.

The goal is to identify each classification position in the chain and downstream and upstream demands for each activity and product. Considering the statistical system, it was analyzed the National Classification of Economic Activities (CNAE and the Mercosul Common Nomenclature (NCM. It was consulted the statistical information of the Brazilian Institute of Geography and Statistics (IBGE and the United Nations (UN, besides the specific scientific literature. In general, these classifications of economic activities and products are not mutually exclusionary but can overlap each other with relative ease and minimal intervention. Despite the many existing segmentation, both the supply chain and the classifications from this work are set correctly. The productive chain of the oil-juice-citrus Brazilian industry involves these activities: cultivation, production, harvesting, processing of juices and related, industrial utilization of by-products and waste / scrap, packing houses, distribution, marketing and consumption. The products are: agricultural inputs, orange (fruit, juices, essential oils, aromatic waters, terpenes, terpenoids, limonene, fragrance and cosmetics.

    The Oil Law, 1997, established the functions of the Agencia Nacional do Petroleo (ANP) to implement, in its area of competence, the Brazilian national energy politic. The principles of the Brazilian national energy politic include the preservation of national interest, promotion and expansion of the labor market, free competition and the expansion of Brazil's competitiveness in the international market. The ANP started then a series of actions designed to meet, within their sphere of action, the objectives defined by law. These actions include studies to diagnose the capacity and competitiveness of local supplier and inclusion, in the concession contracts, clauses aimed to stimulating the development of local suppliers and ensure equal treatment, by the new dealers, of local suppliers and foreign. From a historical overview, the development of these actions, and the improvements made possible by the management of concession contracts, have reached their goals. The results obtained so far indicate that the actions carried out are a valid and effective tool in stimulating development of local suppliers. (author)

    This main objective of this work is to present the obstacles to the Brazilian participation in the international ethanol and sugar market, specially in the European Union. Therefore it is emphasized the main reasons which conduct Brazil to discuss in the International Trade Organization the production quota system impositions and the heavy subsidy exportation used in the European Union. In despite of improving the negotiation arguments, it has been felt at the most recent International Trade Organization meeting that the Brazilian interests has got to confront international barriers to punish the Brazilian sugar with an high tax importation as in the European Union. Due to those difficulties, the possibility of opening a larger ethanol market, mainly in those countries which wish to reduce pollution emission, mixing anhydrous alcohol to gasoline appeared as a good alternative. Actually the European Community members have strategic reasons to maintain the sugar production subsidies. Brazil and most of the European Community members have been discussing an agreement to reduce the subsidies. The Brazilian victory on the appeal made in the International Trade Organization, on August the 4th; against the subsidies to the sugar conceded by EU, provoked rejection of many. (author)

    Ethanol has been recently of great interest due to two main reasons. First, it is a viable alternative to oil derivates used in light vehicles, which price has been substantially raised in the last years. In second place because ethanol is a renewable source of energy, that mitigates the emission of greenhouse effect gases. Although Brazil is losing its leadership of ethanol production for the United States, it raises internationally as the leading country to develop its ethanol production from biomass. Differently from the American system which relies on corn as principal raw material, Brazilian ethanol is produced from sugarcane. The Brazilian route shows up as much more competitive and much less pollution contributor than the American one. The objective of this work is to analyze the leading aspects of the Brazilian Innovation System built around the sugarcane industry. The Brazilian success in terms of sugarcane can not be understood just as based in a natural comparative advantage, but it is a result of accumulation of efforts which ended in a virtuous trajectory of technological learning, relying, mostly, in incremental innovations. That process had, as inflection point, the Pro Alcohol Program, launched after the first oil crisis in 1973. From that Program on, the agricultural industry started the diffusion of innovations making possible constant increases of productivity and cost reduction on its production. The technological advance brought benefit to the alcohol and sugar production, of which Brazil became the main world producer. This work is based on the approach of national systems of innovation, according to which the innovative performance of a country, region or even a sector, can not be learned only by focusing the efforts and performance of the companies. Innovation results from the interaction of actors from different institutional nature. To analyze the institutional arrangements as the basis to the innovative process, this work will get

    The antioxidant responses in saplings of Tibouchina pulchra (a native tree from the Brazilian Atlantic Rainforest) exposed around an oil refinery in the city of Cubatão (SE Brazil), varied during the exchange of its power generation source, from boilers fueled with oil to a thermoelectric fueled with natural gas. The redox potential changed in response to an interaction of air pollution and meteorological parameters, indicating that the pro-oxidant/antioxidant balance was not reached after the exchange of the power generation system. The gain in environmental quality in the region was not achieved as expected due the technological modernization, at least relative to oxidative stressors. These conclusions were based on results of analyses of enzymatic antioxidants: superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR); non-enzymatic antioxidants: reduced, oxidized and total ascorbic acid (AsA, DHA, totAA) and glutathione (GSH, GSSG, totG), their redox state (AsA/totAA and GSH/totG) and an indicator of lipid peroxidation (MDA). We also applied exploratory multivariate statistics in order to verify if the temporal sequence of changes in the plant redox capacity coincided with changes in the profile of air pollution, climatic conditions or with their interactions and if the environmental benefits that would supposedly be promoted by the mentioned exchange of power generation system were achieved in the region.

    Brazilian legislation establishes that the potentially polluting activities, as is the case of the ports and terminals, possess plans of emergency for spilling in order to prevent impacts to the physical, socio cultural and of the work environment. The Federal Law n. 9966, of April 2000, known as the 'Law of the Oil' established the basic principles, to be obeyed for the companies, for harmful or dangerous oil movement and other substances in ports, terminals, platforms and ships in waters under national jurisdiction. The Law defines that the emergency plans are a set of measures that determine the responsibilities and the actions to be unchained after an incident immediately, as well as define the human resources, material and adequate equipment to the prevention, has controlled and combat to the pollution of waters. The CONAMA n. 398, of June of 2008, create a standardization of those procedures, so that there is an integration among the several emergency plans in a certain area. This article has for objective to accomplish a diagnosis in the several institutional programs of emergency to identify the current situation in the organized and terminal ports specialized in liquid barns, evaluating, when possible, it rationality of support logistic, the organization of operational administration and integration.

    The situation in the oil industry in Brazil has a history that predates the creation of PETROBRAS, dating from approximately end of the nineteenth century, but only with the state economic sector that was spent to develop the full steam, so that Law No. 2.004 / 53 was the real point for the insertion of that product domestically. However after the issue of Constitutional Amendment No 09/95, requiring the creation of a law for the industry itself, from then on PETROBRAS is no longer the only one in the industry, and will act in competition with other private companies. With the promulgation of Law 9.478/97 has been subject to supervision and control by the National Petroleum Agency, Regulatory Agency sector. In this context the present study aims to show how the state was in the national market and its integration within international oil, bringing relevant points as the paid procedure disciplined in Article 22, Section 2 of the law cited, and its position as a leader in offshore production.

    Brazilian society declares no intention to development a nuclear artifact. This is on its Constitution. The submarine of nuclear propulsion may be used as a weapon of defense and, therefore, has a peaceful objective. Nationalism must be applied only to benefit the society. Nationalist attention has always been devoted, at various occasions, to the Brazilian nuclear sector. However, since Brazilian society has many needs and the Brazilian government always had numerous energy options, this sector has not been developed as it could be. Other successful applications of nuclear technology, besides electric generation, are not considered here. At present, the country is experiencing a moment of harassment of liberal forces. It is difficult to know if the population understands what is going on, due to the traditional media control. This media belongs to the capital. The rise and the fall of the nationalist strand in a country follow a global tendency and also depend of actions of the international capital. In nationalist periods, more decisions with positive social impact are taken. Therefore, sovereignty is necessary to increase the benefits to society. Unfortunately, the Brazilians deceived by the companies of mass communication and corrupt political leaderships allow the country to be dominated. Even the armed forces had their projects paralyzed. The nuclear sector, as all other, suffers with the low budget and the future is difficult to predict. (author)

    Full Text Available This work makes an analysis of the determinants of Corporate Social Responsibility (CSR of Brazilian firms, as proxied by firm membership of the ISE Index of BM&FBOVESPA. Besides other proposed determinants of CSR present in the literature (firm size, profitability, growth opportunities, the work examines ownership concentration and the persistence on CSR status. Logit regression estimates have been run for a sample of 1649 firm-year observations in the period 2006-2011. The findings show that CSR of Brazilian firms is inversely correlated to its ownership concentration indicating that controlling voting shareholders may not see social concerns as a priority. Besides, firms tend to maintain their present CSR status. The results also indicate that leading CSR firms are larger, face more growth opportunities, and are persistent in their superior CSR situation.

    An in-house validated GC-MS method preceded by acid-catalysed methanolysis was applied to 97 samples of vegetable oils and fats marketed in Brazil. The levels of the compounds ranged from not detected (limit of detection = 0.05 mg kg(-1)) to 5.09 mg kg(-1), and the highest concentrations were observed in samples containing olive pomace oil and in products used for industrial applications, such as palm oil and its fractions (olein and stearin). The content of diesters and monoesters was also investigated by employing solid-phase extraction on silica cartridges, indicating that the majority of the compounds were present as diesters. This study provides the first occurrence data on these contaminants in Brazil and the results are comparable with those reported in other countries.

    The benefits of antiretroviral therapy for HIV-infected subjects have been limited by an increased risk of metabolic and cardiovascular diseases. The objective of this study was to assess the effects of a low dose of marine omega-3 fatty acids on inflammatory marker concentrations in HIV-infected subjects under antiretroviral therapy (ART). This was a randomized, parallel, placebo-controlled trial that investigated the effects of 3 g fish oil/day (540 mg of eicosapentaenoic acid-EPA plus 360 mg of docosahexaenoic acid-DHA) or 3 g soy oil/day (placebo) for 24 weeks in 83 male and non-pregnant female HIV-infected adults on ART. There were no differences between groups for the measures at baseline. Multilevel analyses revealed no statistically significant relationship between the longitudinal changes in high sensitivity-C reactive protein (hs-CRP) (Wald Chi2 = 0.17, p = 0.918), fibrinogen (Wald Chi2 = 3.82, p = 0.148), and factor VIII (Wald Chi2 = 5.25, p = 0.073) with fish oil. No significant changes in interleukin-6 (IL6), interleukin-1 beta (IL1-beta) and tumor necrosis factor-alpha (TNF-alpha) serum concentrations were observed with fish oil supplements for 12 weeks. Compared to placebo, a low dose of 900 mg omega-3 fatty acids (EPA plus DHA) in fish oil capsules did not change hs-CRP, fibrinogen, factor VIII, IL6, IL1-beta and TNF-alpha serum concentrations in HIV-infected subjects on ART. Further investigations should consider the assessment of more sensitive inflammatory markers or higher doses to evaluate the effects of marine omega-3 fatty acids in this population.

    This study evaluates the implications of different geopolitics scenarios over the productive and technological strategies for exploiting national oil resources. Initially, it discusses the international oil market fundamentals, focusing the dynamics of the light-heavy prices differential. Then, it analysis the effects three possible scenarios over such market fundamentals: Strong OPEC due to 'reinforcement of the price band mechanism discipline'; Weak OPEC due to 'market contestation' (productive empowerment of non-OPEC countries or quitting of OPEC member-countries interested in getting more productive autonomy - such as Algeria, Nigeria and, eventually, Iraq); and, Weak OPEC due to 'strategies to reduce geopolitics vulnerability' (minimization of supply disruption risks). Afterwards, it evaluates the impacts of those scenarios over the productive and technological strategies for exploiting national oil resources. Finally, it concludes that the scenarios of Strong OPEC and Weak OPEC due to 'strategies to reduce geopolitics vulnerability' are the most favorable for the exploitation of national oil resources, whilst the scenario Weak OPEC due to 'market contestation' would challenge the oil companies operating in the country to generate productive and technology strategies which strongly promotes E and P cost reduction in Brazil in order to maintain the competitiveness of the national oil.

    This paper analyses the institutional model adopted for the reform of the oil industry in Brazil, beginning with the approval of Law n. 9.478 by the Brazilian Parliament in 1997. The reform of the Brazilian oil industry took place in the context of the reforms of the world's national economies throughout the 1980's and 1990's. From this worldwide process of reform stemmed a huge increase in the international capital flow directed to long-run investment opportunities in the economic infrastructure sectors. The aim of this paper is to analyse both the regulatory model for the oil and gas upstream activities in Brazil and the bidding model adopted at Brazil's National Petroleum Agency's auctions for the acquisition of exploration areas. This paper is dedicated, in its entirety, to Prof. Carmen Alveal (in memoriam), whose knowledge, support, encouragement and friendship were, for me, the most important of all, professionally and morally.

    2004-07-01

    This paper is focused on the elaboration of a standardization model for the existing flow of information between the Petroleum National Agency (ANP) and the concessionaire companies in the event of the discovery of any potentially commercial hydrocarbon resources inside their concession areas. The method proposed by Rosa (2003) included the analysis of a small sample of Oil and Gas Discovery Assessment Plans (PADs), elaborated by companies that operate in exploratory blocks in Brazil, under the regulatory context introduced by the Petroleum Law (Law 9478, August, 6th, 1997). The analysis of these documents made it possible to identify and target the problems originated from the lack of standardization. The results obtained facilitated the development of a model that helps the creation process of Oil and Gas Discovery Assessment Plans. It turns out that the standardization procedures suggested provide considerable advantages while speeding up several technical and regulatory steps. A software called 'ePADs' was developed to consolidate the automation of the several steps in the model for the standardization of the Oil and Gas Discovery Assessment Plans. A preliminary version has been tested with several different types of discoveries indicating a good performance by complying with all regulatory aspects and operational requirements. (author)

    ANP (National Agency of Petroleum, Natural gas and Biofuels), through auctions of exploratory blocks in the subsequent years from the break of the monopoly of PETROBRAS with the Law 9.478 of 1997, had important role in the opening of the section and in the attainment of the self-sufficiency of petroleum. However the petroleum production in ripe and marginal fields were left off, since the initial interest in the first rounds was to attract the major companies. - International Oil Companies (IOC) - when ANP granted great blocks offshore. Ripe fields are defined as fields in phase of irreversible declination and marginal fields are also defined as economical concept, certain for business decision and external economical factors (price of the oil, etc.). Canada and USA, worldwide leaders in the market of petroleum and gas, possess politics that benefit and maintain the small companies protected of the competition of INOC's by assuring small companies finance through the guarantee of proved reserves of oil. This paper assemble Canadian and American experiences in regulation for small companies investments and compares it with Brazilian financing types, which is restricted due to the Brazilian finance agent's despite about oil and gas activity.

    2009-07-15

    The author describes the decline of Venezuela's oil industry as well as President Chavez' reaction to Venezuela's budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela's poor and he is searching desperately for ways to extract yet more from Venezuela's dysfunctional economy. As funds run out, Venezuela's expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela's impoverished masses, still supportive of Chavez during February's elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [Dutch] De auteur beschrijft de teruggang van de olie-industrie van Venezuela en de reacties van president Chavez op de budgettaire crisis in Venezuela. Politisering, dalende investeringen en de verplichtingen m.b.t. de overvloed aan sociale uitgaven zorgen er voor dat de nationale oliemaatschappij Petroleos de Venezuela niet in staat is om efficient te produceren en de productie op peil te houden. Dalende olie-productie en lagere olieprijzen zorgen er ook voor dat de president niet in staat is om de rijkdom te verdelen over de armen in Venezuela. Hij is op zoek naar manieren om meer te halen uit de slecht functionerende economie. Zijn dure buitenlandse Venezuela beleid, onder meer door ondersteuning van regionale bondgenoten, in het bijzonder Cuba, en het zoeken naar export mogelijkheden, behalve naar de USA, pakt fiancieel gezien slecht uit. De verarmde massa's van Venezuela steunden Chavez nog in de verkiezingen in

    The emissions of Greenhouse Gases (GHG), the resulting intensification of the greenhouse effect and its relation with climate change, have been pointed out as serious global problem. For this reason, the Kyoto Protocol was established, within the United Nations Framework Convention on Climate Change (UNFCCC), with the objective of setting up directives and goals to the stabilization and reduction of GHG emissions. In its Article 12, the Kyoto Protocol institutes the Clean Development Mechanism, an important flexibility instrument to Annex 1 Parties in achieving their emission reduction targets through project implementation in developing countries (non-Annex 1 Parties), promoting Sustainable Development and incurring and lesser costs of emission reductions. Any project, to be qualified within the Clean Development Mechanism, must fulfill the eligibility criterions fixed by the Kyoto Protocol, which are: promotion of Sustainable Development and assurance of the project additionality. In Brazil, the sugarcane industry is a promising opportunity of developing these kind of projects, specially by means of the cogeneration from sugarcane residues. This paper analyses the Additionality of this sort of projects, in the light of the criterions defined by the UNFCCC, with special attention to the two Brazilian cases registered in the CDM Methodologies Panel.

They indicate that including the value of changes in price volatility often makes very little difference to the results of cost-benefit analyses, but more work has to be done on quantifying, among other things, consumers’ risk aversion and the background standard deviation in total consumption......This paper contains a tentative suggestion of how to take into account the value of changes in price volatility in real world cost-benefit analyses. Price volatility is an important aspect of security of supply which first of all concerns physical availability, but assuming that consumers are risk...... averse, security of supply can also be viewed as a matter of avoiding oscillations in consumption originating from volatile prices of for instance oil. When the government makes transport-related choices on behalf of the consumers, the effect on oscillations in general consumption should be included...

    2016-01-01

    This paper presents an economic assessment of Brazilian agribusiness and its relationship with other economic sectors. It was found that, in 2011, agribusiness had a share of 18.45% (basic prices) and 19.77% (market prices) of Brazilian GDP. The tax burden of agribusiness (20.68%) was higher than that of other sectors (13.59%), despite agribusiness being a major contributor to the generation of foreign exchange, employment, and essential products, such as food. Brazilian agribusiness is a major employer, responsible for 29.39% of national employment. However, its average income is lower than in the other sectors of the Brazilian economy. Finally, agribusiness was found to be the biggest generator of foreign exchange, with a positive balance of trade. It was possible to conclude that agribusiness forms a strong link between agriculture and livestock, industry, and services in other economic sectors. For this reason, it can be said that the development of agribusiness is highly relevant to the process of Brazilian economic development and is therefore important to the progress of economic policies.

    The present work aims to present an overview of the Brazilian petroleum derivatives market following the loosening of PETROBRAS's monopoly in 1997, and to highlight the redefining of the roles of the traditional actors in this sector - refineries and petrochemical complexes - as well those of the new players - the formulators and importers. Regulation of this new model following the opening of the market has been important in establishing a competitive environment, while the competitive strategies adopted by companies have undoubtedly been fundamental to their survival. Along with these changes, this work also considers other aspects of the market, such as: the insufficiency of domestic production to meet the growing demand for derivatives, mainly LPG, naphtha and diesel, making Brazil more dependent on imports; and the technological and capacity limitations of the refinery sector, which create an impediment to the processing of the country's domestic, typically heavy crude, oil production, the offer of which is currently increasing, while excess production is destined for export. While the overall effect of a scenario favorable to internationalization is to make companies more vulnerable to the global politico-economic conjuncture, it also opens the possibility for them to access new technologies and markets, which is crucial for their development and increased competitiveness. This article presents examples of alternatives encountered by the refining sector in its efforts to meet market necessities. (author)

    Biasetto, Bruno Henz

    This dissertation analyzes the development of the Brazilian oil industry and its impact on the economic development of Brazil from the beginning of the "Brazilian Miracle" (1968-1973) to the end of the Fernando Henrique Cardoso's second term as president (1995-2002). The dissertation explores the closely intertwined nature of Brazil's oil industry and its macroeconomic development, shedding new light on the history of Petrobras (the Brazilian state oil company), and on other key topics of Brazilian economic history, including the Debt Crisis of the 1980s and the role of neoliberalism in Brazil. The argument is that oil policy shaped the national economy and the Brazilian state in this period. Attention to the oil industry, and to Petrobras in particular, was crucial to the establishment of diplomatic and economic policy, and to conflict within the Brazilian state. Finally, this dissertation seeks to illuminate Brazil's place in the global oil industry and how that has shaped Brazil's global economic standing.

Compreende os resultados de uma pesquisa que apresenta a gestão estratégica de custos, contribuindo para a obtenção de vantagem competitiva de empresas do setor de aviação comercial brasileiro. De natureza exploratória e de característica longitudinal, faz uso da pesquisa documental para coleta de dados. Para apresentação e análise dos dados, utilizou-se da estatística descritiva. Ao final da investigação, demonstra-se que o determinante de custos com tecnologia das aeronaves tem influência direta nos principais custos do setor: o consumo de combustível, o custo de manutenção e a depreciação ou arrendamento de aeronaves. A GOL demonstrou êxito ao alinhar o determinante de custos com tecnologia das aeronaves e apresentou os menores custos dentre as empresas pesquisadas. A TAM reestruturou a sua frota de aeronaves e reduziu significativamente seus custos.

    The Law no. 9,478/97 establishes that among its attributions the Energy Policy National Council (CNPE) must review periodically the national energy matrix. This paper aims at discussing the scenarios considered in the current revision based on an integrated energy planning approach, identifying its key points and analyzing its eventual consequences, particularly for oil and gas industry. More precisely, it evaluates the effects over the O and G industry of changes in the international and national circumstances. The international key factors focused are, mainly, oil and oil product prices and productive and technological strategies of O and G companies. The national key factors discussed fuel prices, inter-fuel substitution potentials, efficiency levels, potentials of new discovers and characteristics of Brazilian reserves of oil and natural gas (on-shore or off-shore E and P, oil or gas fields, API degree density, sulfur and acid contents), and adequate energy infra-structure (necessity of distribution and transportation grid expansion, refining capacity etc.). Such discussions have important implications for public policies and corporate strategies. (author)

    This publication contains five papers that were written as a part of the GEF project, The Economics of Greenhouse Gas Limitations. The main goal of the project was to assess the greenhouse gas reductions and incremental costs of mitigation option sin Ecuador, Argentina, Senegal, Mauritius, Vietnam, Indonesia, Estonia and Hungary. In addition, regional studies were conducted for the Andean Pact nations and Southern Africa to assess various aspects of regional co-operation in reducing greenhouse gas emissions. The GEF study also involved the development of a methodological framework for climate change assessment, with a special emphasis on developing countries. These guidelines have been published in a separate document, Economics of Greenhouse Gas Limitations: Methodological Guidelines. The papers in this publication focus on various methodological and policy aspects of greenhouse gas mitigation at the sectoral level, and are outgrowth of work performed on other parts of the GEF project.

    With the depletion of traditional energy resources and the rising demand for energy, the exploitation of heavy oil resources is increasing. The aim of this paper is to present the heavy oil sector and to show which are the factors influencing heavy oil growth and production. A large part of heavy oil reserves lies in the Americas, with about 45% of the world's reserves in Latin America and over 35% in North America. The development of the heavy oil sector is dependent on economic, technological and environmental factors; greenhouse gas policies have important impacts on the development of the heavy oil industry as well as downstream market access. This presentation highlighted the great potential that North and South America have in terms of heavy oil but that the development of this sector will depend on several factors.

    The author uses the Michael Porter framework, (from the University of Harvard), about the 'Competitive Advantage of Nations', as a theoretical instrument to analyze the Brazilian oil industry. The document studies, specifically, the related and supporting industries, one of the four determinants that, according to the author, promote the creation of national competitive advantages; the others are: the factors conditions; the demand conditions; and the firm strategy, structure and rivalry. The study aims at building a general view of competitiveness for the so called supply industries to the oil sector, which have a fundamental role in this model. Although Brazil has developed, with the leadership of PETROBRAS, a complex industrial system, this structure of related and supporting industries will have to face new challenges, having to improve efficiency, reduce costs and redefine its global strategies.

    Breaking the monopoly of PETROBRAS for the activities of exploration and production of oil and natural gas has occurred in Brazil in 1995 by the Constitutional Amendment No 9 followed by the promulgation of the Law 9.478 of 1997, the 'Law of Oil' and the creation of the Agencia Nacional do Petroleo - ANP, with powers to regulate, recruit and monitor the oil and natural gas industry. The new regulatory framework has established the award granted by the State, through bids organized by the ANP, of the oil and gas exploration and production activities. This new model has established that the offers to purchase blocks must be composed by the Signature Bonus, Minimum Exploration Program and percentages of Local Content for the stages of exploration and development of production. As a result of market opening and the completion of bids over these 10 years, there has been a significant expansion of investment in the industry, revealing that the demands of Local Content rightly acted as a strong mechanism inducing the participation of local industry supplier of goods and services. In practical terms, in 1997 the participation of the sector of oil and gas in the Brazilian GDP was approximately 2.5% and now comes to 10.5%, or each R$ 100.00 generated in the country, R$ 10.50 come from the sector of oil and gas.

    Full Text Available In heterodox literature, the industrial sector is considered strategic for economic development. Consequently, reducing the contribution of this sector in the production of the country before it has reached the stage of economic maturity, affects the productive dynamics and slow technical progress. The appreciation of the real exchange rate is seen as one of the factors responsible for the reduction of the external competitiveness of Brazilian manufactures, and this exchange rate valuation may be occurring due to the differences between domestic and international interest rates. Given this context, the aim of this study is to evaluate the impact of changes in the monetary and exchange rate policy and in the composition of the total exports on the performance of the Brazilian economy using a structuralist model. The results reinforce the importance of the manufacturing sector to economic growth, especially in a competitive exchange rate environment.

For each of the country’s 5 regions (Southeast, Central-West, North, Northeast and South the prevailing agroforestry systems holding animals are presented, their potential and constraints discussed and research needs identified. In general, such systems are not broadly adopted, mainly because of their level of complexity compared with traditional systems, as well as some lack of understanding by farmers regarding their benefits. To change this situation, in the last 5 years, the Brazilian Government has allocated financial resources in terms of credit for development as well as for research and technology transfer addressing ICLF systems, including good agricultural practices and mitigation of greenhouse gas emissions. The goal is to improve competitiveness of the Brazilian agribusiness sector.

    The thriving of the national oil and gas production depends in major part on the effectiveness of the import operations at non-definitive title made under the customs special regime named Special Customs Regime for Export and Import of Goods for Oil and Natural Gas Exploration and Production Activities - REPETRO. This regime has not totally complied with the targets it has been conceived for, that is, to enable the development of the oil and gas industry at the least import costs in a legal stable environment. This regime is a precarious norm, conceived in a hurry, aiming solely at not unveiling the big threat to the forming of partnerships among companies acting in the commerce of import and/or export of equipment for the exploration and production in the Brazilian territory, that is, the intent of the Federal Fiscal Administration to using the import tax, an extra-fiscal tax by its nature, as a mere collecting instrument. This fact becomes evident from a more detailed analysis of certain aspects of the REPETRO normative structure. (author)

    The product development process (PDP, if well-structured and managed, can become a business process that directly influences the companies' competitiveness increase. The PDP in Brazilian SMEs in the agricultural machinery and implement industry Sector (AMI is little known since most publications on product development focuses on the reality of large and multinational companies, which have a quite different structure from SMEs. The purpose of this paper is to characterize and analyze the management maturity profiles of the product development process in small and medium sized Brazilian companies in the agricultural machinery and implement industry sector located in the state of São Paulo. Therefore, the addressed actions of PDP improvements in those companies can be undertaken. A survey research was conducted in 40 companies. An in loco interview was applied to the respective individual in-charge of PDP by means of a structured questionnaire. For the data analysis, descriptive statistics and the multivariate cluster analysis techniques were used. The findings indicated that the SMEs in AMIs of the state of Sao Paulo present a heterogeneous structure with respect to PDP management. Three groups of companies were identified in the sample with different maturity PDP profiles: Group I (20% of companies in the sample, Group II (50% of the sample, and Group III (30% of the sample. Differences in the management of PDP were observed, especially among companies of Group I (smallest level of PDP maturity and Group III (highest level of PDP maturity. However, despite the differences in PDP management presented in the groups of companies, according to the literature on PDP management, all groups are in the basic (initial maturity level of PDP. The identification of the maturity level, in which these companies are, can help the determination of activities that link the internal actions to improve the PDP of these companies and the proposal of specific public policies that encourage the

    Full Text Available The permeability of Brazilian Eucalyptus grandis and Eucalyptus citriodora wood was measured in a custom build gas analysis chamber in order to determine which species could be successfully treated with preservatives. Liquid permeability was tested using an emulsion of Neen oil and a control of distillated water. Air was used to test the gas phase permeability. For both Eucalyptus grandis and Eucalyptus citriodora, the longitudinal permeability of gas was shown to be about twice as great as the liquid phase permeability. No radial permeability was observed for either wood. The permeability of air and water through the sapwood of Eucalyptus grandis was greater than that through the sapwood of Eucalyptus citriodora. The permeability of neen oil preservative through the sapwood of Eucalyptus grandis was also greater than through the sapwood of E. Citradora, but the difference was not statistically significant. Scanning Electron Microscopy images showed that the distribution and obstruction in the vessels could be correlated with observed permeability properties. Irrespective of the causes of differences in permeability between the species, the fluid phase flux through the sapwood of both species was significant, indicating that both Eucalyptus grandis and Eucalyptus citriodora could be successfully treated with wood preservative.

    Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

    2017-03-01

    The paper examines the impacts of financial development on sectoral carbon emissions (CO 2 ) for environmental quality in Malaysia. Since the financial sector is considered as one of the sectors that will contribute to Malaysian economy to become a developed country by 2020, we utilize a cointegration method to investigate how financial development affects sectoral CO 2 emissions. The long-run results reveal that financial development increases CO 2 emissions from the transportation and oil and gas sector and reduces CO 2 emissions from manufacturing and construction sectors. However, the elasticity of financial development is not significant in explaining CO 2 emissions from the agricultural sector. The results for short-run elasticities were also consistent with the long-run results. We conclude that generally, financial development increases CO 2 emissions and reduces environmental quality in Malaysia.

    Full Text Available The present research seeks to understand to what extent companies in emerging countries, specifically, Brazilian, adopt dominant management practices, the so-called Euro-American practices, possess their one, or show a syncretism between the two. Methods: Mixed research. One phase was to collect data using a survey about cultural dimensions adopted from GLOBE (House 1998 management practices and also from Brazilian academy. Another was to collect data through interviews, which were analyzed in parallel. Results: Of the seven dominant cultural dimensions, indigenous practices influenced two. Another three were influenced by dominant management practices. Two of the local dimensions, even with internationalization, merged practices with Brazilian cultural traits. Even so, the practices derived from Jeitinho diminished relative to the international relations and experience of managers. Conclusions: The paper shows the existence of powerful Brazilian Indigenous Managerial Practices such as personalism and formalism. These practices have great influence on international business negotiations. On the other hand, it also shows that there are still dominant managerial practices specially in the case of more internationalized Brazilian managers

    Full Text Available The sugarcane industry contributes approximately 2% to the Brazilian GDP, and generates more than 600,000 jobs in nearly a thousand cities. This study aims to determine the main variables that affect the growth of the Brazilian sugarcane sector. For this, econometric techniques were used to quantify the impact of each variable studied in the growth of Gross Domestic Product in this sector from 1980 to 2013. A specific analysis of the impact of the 2008 credit crisis on growth this sector was also performed. The results showed that the variables that impact the growth of Brazilian sugarcane industry are: exchange rate, fuel alcohol consumption, and the average price of a barrel of petroleum. Moreover, it was found that the 2008 crisis contributed negatively to the GDP of this sector. It was possible to conclude that the crisis in this sector had its origin in the optimism in this sector, due to the growth of the sector in 2006 and the global factors in 2008, which was reflected in variables such as exchange rate and the consumption of alcohol fuel, that negatively impacted the sector.

  15. [Brazilian colonization in the Paraguayan agricultural frontier].

    Science.gov (United States)

    Neupert, R F

    1991-04-01

    This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

    2012-05-01

    Full Text Available This study aimed to identify whether 23 sectors of Brazilian manufacturing industry spent efficiently in innovation activities in the years 2003 and 2005, through data envelopment analysis, especially by the model of variable returns to scale. It was found that the level of efficiency has reduced considerably over the years, with the average score from 0.82 in 2003 to 0.68 in 2005, and in the past year, have been a shift from the efficient unities. The only efficient industries in the two years were linked to the production of oil, non-ferrous metals and automobiles in general. The conclusion is, after all, that maintaining the levels of profitability in terms of innovation expenditure of the sectors of processing industry depends on a more efficient use of resources in order to achieve or, if possible, overcome the technological standards international.O presente estudo buscou identificar se 23 setores da indústria de transformação que investiram em atividades de inovação foram eficientes em 2003 e 2005, por meio da análise envoltória de dados, principalmente pelo modelo de retornos variáveis à escala. Verificou-se que o nível de eficiência reduziu-se consideravelmente ao longo dos anos, com o escore médio passando de 0,82 para 0,68 entre 2003 e 2005, além de, neste último ano, ter ocorrido uma mudança em relação às unidades eficientes. Os únicos setores eficientes nos dois anos foram os ligados à produção de derivados do petróleo, de metais não ferrosos e de automóveis em geral. Conclui-se, afinal, que a manutenção dos níveis de lucratividade em função dos gastos com inovação dos setores da indústria de transformação nacional depende de uma maior eficiência no uso destes recursos, com o intuito de alcançar ou, se possível, ultrapassar os padrões tecnológicos internacionais.

  20. Brazilian physicians hold national strike against medical insurance companies.

    2012-01-01

    The Brazilian Health System has two different forms of access, public and private. The purpose of the public health system is to provide universal, complete access, free of charge, for the entire population. The private sector is composed by people who have private insurance. Nowadays, about 43 million Brazilians, or 26.3% of the population, have private health insurance. The main motivations of the physicians for the strike were the low payment for medical services and the constant interference of the private health insurance companies in medical autonomy. For this reason, Brazilian physicians held a 24-hour strike against the Medical Insurance Companies that did not accept to negotiate new fees in almost all Brazilian states. At least 120,000 physicians from all specialties stopped elective activities during that day, only providing urgent or emergency care. It is estimated that the strike affected 25 to 35 million Brazilians, about 76% of the total number of medical insurance users. Copyright © 2012 Elsevier Inc. All rights reserved.

    This paper focuses on supplying electrical power for remote communities of the Brazilian Amazon using regional biomass, specifically palm oil biomass, as a primary energy source. The use of Straight Vegetable Oil (SVO) as fuel, is indicated for isolated communities, where the hydro plants or the installation of transmissions line are impracticable. The use of vegetable oils produced in the communities, is a solution when an adequate infrastructure to extracting the oil is available. Brazil is able to use an enormous diversity of vegetable oils, due to a great variety of plants, and the favorable climatic conditions. Technical, economic, environmental and social aspects are analyzed in order to provide a basis for electrical power supply viability in these communities. A case study is presented focused on a typical Brazilian Amazon community located in the State of Para in order to demonstrate the applicability of the proposed viability strategy. (author)

    2014-05-01

    Full Text Available With Brazil and the BRIC economies becoming more important to world growth and financial investment, it is important to understand the inner-workings of the financial institutions that will help spur on continued economic growth. This article focuses on the recent history of the market structure of the Brazilian banking sector as well as the effects of the global financial crisis of the late 2000s on the overall relative efficiency of the Brazilian banking sector by using Data Envelopment Analysis. The period studied—2002-2011—shows a marked decrease in overall relative efficiency in the Brazilian banking sector. The negative effects were felt across the board regardless of bank size or ownership type. Small and medium sized banks had the most significant drop in relative efficiency while larger banks were able to weather the crisis more successfully. This alludes to the idea that “Bigger is Better” when dealing with financial shocks to banking efficiency, and would allow us to summarize that the Brazilian banking sector is not participating in the “Quiet Life” of concentrated markets. Also, looking at ownership type, the study shows that Brazilian banks that are controlled by the government were ranked as the most efficient types of banks. Their foreignowned counterparts, however, were ranked as the least efficient and had a larger drop in overall efficiency and participation during the financial crisis than their domestic Brazilian counterparts. The article contributes to the continued need for more information on the Brazilian banking sector’s history and development.

In parallel is growing the pressure of the society, for a more responsible performance from the oil companies. In reply, the oil industry is adopting managing systems aiming to manage its environmental and social impacts. It is expected that in a first moment, the oil companies controls its social and environmental risks, for what this methodology was developed. This proposal supports the oil companies to incorporate the social and environmental variables into the economic dimension of their business, using a set of indicators. Allowing to analyze the possible influence of the business on the internal and external quality. More than analyze, making possible to prioritize a sustainable business. The application of this methodology will prevent additional costs that could be spent for those companies that did not consider the environmental and social costs of their business, and contributes also to facilitate the communication between the companies and their stakeholders.

  7. Is oil consumption constrained by industrial structure? Evidence from China

    Science.gov (United States)

    Jia, Y. Q.; Duan, H. M.

    2017-08-01

    This paper examines whether oil consumption is constrained by output value, applying a cointegration test and an ECM to the primary, secondary, and tertiary sectors in China during 1985-2013. The empirical results indicate that oil consumption in China is constrained by the industrial structure both in the short run and in the long run. Regardless of the time horizon considered, the oil consumption constraint is the lowest for the primary sector as well as the highest for the tertiary sector. This is because the long-term industrial structure formation and the technological level of each sector underlines the existence of long run equilibrium and short run fluctuations of output value and oil consumption, with the latter being constrained by adjustments in industrial structure. In order to decrease the constraining effect of output value on oil consumption, the government should take some measures to improve the utilization rate, reducing the intensity of oil consumption, and secure the supply of oil.

    The present work discuss Chinese strategies for making foreign investments in O and G sector, taking into account NOC's huge investment capability and increasing oil demand with sustains China's economic growth. Initially, the effect of China's economic growth rate on international oil market is addressed. The paper also details the relationship between Chinese NOCs and the Government, highlighting their aims and strategies, as well as the results of their results. Finally, this article evaluates how those strategies can affect Brazilian O and G upstream sector. Despite of concerns on Chinese government interference in NOCs management and decision processes, it is show that those State companies pursue much wider objectives, which transcend the mere search for energy security, such as asset diversification, access to new technologies and strengthening of their positions in global economic context. Doing so, those enterprises can become, in the long run, valuable partners of Brazilian PETROBRAS in E and P activities in pre-salt areas, building a win-win relationship not only for the companies involved but also for Brazil and China.

  10. Energy, Pollutant Emissions and Other Negative Externality Savings from Curbing Individual Motorized Transportation (IMT: A Low Cost, Low Technology Scenario Analysis in Brazilian Urban Areas

    Directory of Open Access Journals (Sweden)

    Ursula Maruyama

    2012-03-01

    Full Text Available This article examines the inefficient use of resources in the Brazilian transportation system. The energy use growth and external cost generation in this essential economic sector are considerable, and the trend is towards an increasing problem in the coming years. The continued expansion of Brazilian cities and the increase in demand for mobility is a result of a substantial growth in the number of road transport users, as increased earnings enable lower income groups to acquire and use individual motorized means of transport. The aim of this paper is to estimate the potential gains from reducing individual motorized transport by the year 2020. This investigation concludes that in a conservationist scenario, by prioritizing low cost, low technology public policies—which include operation of Bus Rapid Transit systems, walking and cycling facilities and congestion charges, among others—it should be possible to save over USD 30 billion and USD 26 billion in external transportation and infrastructure costs, respectively, up to 2020. In addition, these public policies can save more than 35 million Tons of Oil Equivalents in energy consumption and avoid almost 4,000 thousand tons of local pollution emissions and 37,500 thousand tons of GHG emissions in the same period.

    2009-10-01

    Full Text Available In this article, we analyze the main non-wood forest products from Brazilian savanna. We studied the behavior and the growth rates of production and prices of almond of babaçu, oil of copaiba, fiber of buriti, leaf of jaborandi, bark of barbatimão, bark of angico, fruit of mangaba, almonds of pequi, from 1982 to 2005. All the products exhibited decreasing production, with exception of the oil of copaiba and almonds of pequi, which showed positive growth rates: 12.9% and 8.5%, respectively. The analysis of prices for most products was not significant, except for barks of barbatimão and angico, and almonds of pequi, which showed positive trends: 10.9%, 6.7%, and 4.6%, respectively. We believe that results were not significant due to the severe variations of the Brazilian currency in the period. We conclude that pequi is the main product from savanna and that oil of copaiba has the biggest increase in the production because most of the production comes from the whole Brazilian Amazon region.

    Dark sectors, consisting of new, light, weakly-coupled particles that do not interact with the known strong, weak, or electromagnetic forces, are a particularly compelling possibility for new physics. Nature may contain numerous dark sectors, each with their own beautiful structure, distinct particles, and forces. This talk summarizes the physics motivation for dark sectors and the exciting opportunities for experimental exploration. It discusses axions, axion-like particles, dark photons, and other dark-sector particles, including sub-GeV dark matter. In many cases, the exploration of dark sectors can proceed with existing facilities and comparatively modest experiments. A rich, diverse, and low-cost experimental program has the potential for one or more game-changing discoveries.

Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

    Full Text Available The 2014 World Cup and 2016 Olympics have stimulated competition for investments in the infrastructure for the transportation of passengers, and they have demanded the integration of all modals of the Brazilian transport sector. Why is the transportation sector considered fundamental for the economy success and for mega-events as the World Cup and the Olympics? Objective: Capacity of the country in attracting investments, modernization of all transportation hubs and for the logistics. For reorganization of urban and inter-urban mobility, the country counts with one principal player, the BNDES (Brazilian Development Bank. For the comprehensive time period between the years of 2010-2016, it has an investment perspective in logistics that can practically come close to the R$ 130 Billion (Brazilian Real, of this sum 43% comes from funds of the BNDES, 37% comes from the private sector and approximately 20% from public agencies. Dividing by transportation modals and applied in consolidated projects, sea port sector requirements will take roughly R$ 15 Billion (14% of the total sum; the railroad sector will have approximately the equivalent of R$ 56 Billion (52% of the total sum; the air transport project (TAV will take 31 billion (29% and the road sector with about 36 billion (34%. In summary, the direct participation of the BNDES in projects that integrate planning and actions of the public agencies for the resolution of the structural problems in urban centers is a determining factor for the growth of the country.

    Full Text Available Technological capabilities (TC play a key role in the competitiveness of firms in industrial sectors. Suppliers in emerging economies often acquire technological capabilities by operating and mastering technologies developed by others and then leveraging this learning to develop indigenous technologies. By reviewing research on firm specific technological capabilities, the development of global value chains and industrial clusters in emerging markets we discuss local suppliers’ insertion and upgrading in the supply chains of new large industrial enterprises. Using the Brazilian shipbuilding industry as context, we investigate and develop propositions related to the ability of local suppliers to develop technological capabilities that permit eventual insertion into the local supply chain. This research has applications for managers and policy makers from other emerging market countries seeking to increase local sourcing through development of local suppliers.

  6. On the Effects of Non-Tariff Measures on Brazilian Exports

    Directory of Open Access Journals (Sweden)

    LUCAS P. DO C. FERRAZ

    Full Text Available This article estimates the effects of TBT/SPS measures on Brazilian exports, based on the recent literature of gravity models. A Heckman selection model - theoretically grounded on the seminal Melitz model of heterogeneous firms - highlights the role played by zero trade flows as well as firm heterogeneity for estimations using gravity equations, two factors usually omitted in standard specifications. We show that both extensive and intensive margins of Brazilian exports are, on average, negatively affected by pre-existing TBT and SPS measures. Moreover, we contribute to the empirical literature by providing comprehensive evidence of the sectoral effects of such measures over domestic exports. We find that TBT/SPS measures - though predominantly harmful - can foster exports in several sectors of the Brazilian economy.

    2013-04-15

    The energy sector is a key driver of the economic pillar of Vision 2030. As the economy grows, urbanization intensifies and incomes increase, corporate and household demand for energy also rises. To meet this growth in demand for energy, the sector needs to increase investments and diversify into more sources of energy such as geothermal and wind power. It is therefore critical that focus is directed towards development and sustainability of the energy sector to ensure delivery of least cost power that will improve Kenya's competitiveness and achieve the Vision 2030 objective of 10% average annual economic growth.

    This article examines empirically the proposition that aid to poor countries is detrimental for external competitiveness, giving rise to Dutch disease type effects. At the aggregate level, aid is found to have a positive effect on growth. A sectoral decomposition shows that the effect is (i......) significant and positive in the tradable and the nontradable sectors, and (ii) equally strong in both sectors. The article thus provides no empirical support for the hypothesis that aid reduces external competitiveness in developing countries.

    two separate occasions were analysed. All samples were examined for labelling, acidity, absortivity at 230 and 270 nm, iodine index, sterols and fatty acids composition, elaidic acid and squalene content. One out of the national brands complied with the label. The acidity was found to be in the range of 0.15%-0.75% C18:1; absortivity has shown the Brazilian brands were mixtures of virgin and refined oils. The range found for iodine index was 85.88-127.46 gl2/100g. All of the locally made oils were outside specifications for sterol content. The fatty acids composition suggested addition of soybean oil. The local brands showed a large amount of transoleic acid (6.6-15.5. The squalene content was in the low range of 14-344 mg/100g. All imported oils complied with the international labelling specifications. The values for acidity, absortivity have indicated that samples were mixtures of virgin and refined oil. The iodine index range (76.43-85.31 gl2/100g was within the specification. Only one out of the samples had transoleic acid content above specified. The range for squalene content was 183-476 mg/100g, which is considered characteristic for olive oil. It is concluded that the Brazilian specifications shall be harmonised with the existing international standards in order to give protection to the consumer of olive oil against fraud and malpractice.

    This article discusses the importance of the industrialization of Brazilian shale based on factors such as: security of the national energy system security, global oil geopolitical, resources available, production costs, oil prices, environmental impacts and the national oil reserves. The study shows that the industrialization of shale always arises when issues such as peak oil or its geopolitics appear as factors that raise the price of oil to unrealistic levels. The article concludes that in the Brazilian case, shale oil may be classified as a strategic resource, economically viable, currently in development by the success of the retorting technology for extraction of shale oil and the price of crude oil. The article presents the conclusion that shale may be the driving factor for the formation of a technology park in Sao Mateus do Sul, due to the city's economic dependence on PETROSIX. (author)

    Full Text Available El crecimiento del sector servicios en detrimento del sector primario, la flexibilidad del mercado laboral y la progresiva incorporación de la mujer a dicho mercado son los cambios más destacados del sector productivo español en los últimos 25 años. Las mujeres en España presentan tasas de desempleo, trabajo temporal y a tiempo parcial mucho mayores que los hombres. Además, las condiciones de acceso al mercado de trabajo y las condiciones en las que éste se desempeña están también muy relacionadas con la clase social. Las mujeres cubren la escasez de servicios públicos destinados al cuidado de las criaturas pequeñas y de las personas mayores o dependientes, y realizan una labor de cuidadoras informales sin reconocimiento social, lo cual les impide el acceso a un puesto de trabajo o su mantenimiento y limita de forma decisiva las posibilidades de desarrollo y progreso profesional. Todo ello indica una clara diferencia con respecto a los hombres en cuanto a la frecuencia de contratos temporales y de tiempo parcial, así como en la segregación laboral, tanto horizontal como vertical. Estos aspectos de segregación son más evidentes en las mujeres de clases sociales menos privilegiadas, en las que se concentran las peores condiciones de acceso al mercado laboral y de trabajo. En España es imprescindible llevar a cabo políticas que ofrezcan servicios que permitan compatibilizar la vida laboral y familiar en condiciones de mayor equidad, tanto en razón de género como de clase social.In the last 25 years, the production sector in Spain has undergone important changes. Among these changes, the important growth of the services sector at the expense of the primary sector, the increasing flexibility of the labour market, and the rise in the female workforce could be considered as the most relevant ones. Spanish women have higher rates of unemployment, temporary jobs and part time contracts than Spanish men. Moreover, job access and work

There is reason to believe that the situation for expatriates from the public sector may be different than for those from the private sector. This study investigated U.S. Department of Defense...... administrators assigned to U.S. embassies worldwide. Results showed that self efficacy, role clarity and role discretion had a positive association with the psychological adjustment of the respondents while role conflict and role overload only had a marginal negative relationship with the criterion variable....... On the other hand, neither international experience nor the effectiveness of preparatory training had any association with the psychological adjustment of respondents.

    Brazil is a country of continental dimensions with widespread regional and social inequalities. In this report, we examine the historical development and components of the Brazilian health system, focusing on the reform process during the past 40 years, including the creation of the Unified Health System. A defining characteristic of the contemporary health sector reform in Brazil is that it was driven by civil society rather than by governments, political parties, or international organisations. The advent of the Unified Health System increased access to health care for a substantial proportion of the Brazilian population, at a time when the system was becoming increasingly privatised. Much is still to be done if universal health care is to be achieved. Over the past 20 years, there have been other advances, including investments in human resources, science and technology, and primary care, and a substantial decentralisation process, widespread social participation, and growing public awareness of a right to health care. If the Brazilian health system is to overcome the challenges with which it is presently faced, strengthened political support is needed so that financing can be restructured and the roles of both the public and private sector can be redefined.

The econometric analysis carried out indicated that the economic variables such as interest rate, unemployment rate, and the level of industrial production were influent factors in explaining the behavior of Tobin's q, both for Brazilian and for U.S. companies. We conclude that the indicator captures relevant information from the major macroeconomic and microeconomic determinants of iron and steel companies, enhancing their potential for the financial analysis of this sector.RESUMENLos modelos para evaluar inversiones que emplean medidas financieras con base en el mercado, como el q de Tobin, aún son incipientes en la literatura nacional. De forma que este estudio tiene como objetivo analizar el comportamiento del q de Tobin en las compañías siderúrgicas brasileñas y norteamericanas, con acciones negociadas en BOVESPA y en NYSE y presentar un estudio econométrico sobre algunos de los principales determinantes macro y microeconómicos en el período comprendido entre 1997 y 2005. El q de Tobin calculado para las empresas brasileñas seleccionadas permaneció en aumento durante el período seleccionado. Con relación al q de Tobin en empresas norteamericanas se comprobó que este indicador fue inferior a 1, indicando desinterés en nuevas inversiones. El análisis econométrico realizado indicó que las variables económicas tales como la tasa de interés, la tasa de desempleo y el nivel de la producción industrial fueron factores de influencia determinantes para explicar el comportamiento del q de Tobin, tanto en empresas brasileñas como en empresas norteamericanas.

    The transportation sector is responsible for more than 50% of all oil products consumed, and it is the fastest growing oil demand sector and the fastest growing source of emissions. During the last 10 years there have been a considerable and growing effort in developing internal combustion gas engines. This effort has resulted in gas engines with efficiencies comparable to the diesel engines and with emissions considerably lower than engines burning conventional fuels. This development offers us opportunities to use natural gas very efficiently also in the transportation sector, resulting in reduced emissions. However, to utilize all the built in abilities natural gas has as engine fuel, the natural gas composition must be kept within relatively narrow limits. This is the case with both diesel and gasoline today. A further development require therefore specified natural gas compositions, and the direct use of pipeline natural gas as today would only in limited areas be acceptable. An interesting possibility for producing a specified natural gas composition is by LNG (Liquid Natural Gas) production. (EG)

This study investigates: (a whether economic linkages of the mining sector related with other economic sectors in East Kalimantan, (b who gets benefit from such mining activities; (c how is the impact of mining sector for rural and urban households; and (d what happens if coal mining, oil and gas productions are completely depleted. The quantitative analysis framework using Input-Output and Social Accounting Matrix Tables in period 2009-2010 has been implemented as main data set. The result shows that mining sector was underdeveloped sector in East Kalimantan, including Kutai Kartanegara district. Activities from mining sector tended to give benefit for the owners of capital, which is larger than that benefit for workers employed. Structural Path Analysis (SPA shows that urban households gain the greatest advantages from the activities of this sector. The result also shows that the total output decreased by 65.12% when the mining, oil and gas dissapeared. A drastic reducing income after mining and oil and gas era will have an impact on the decline in the purchasing power in the region. However, the interesting finding of this research shows that the loss of mining and oil or gas sectors actually increases the strength of employment multiplier by 19%.

  10. Empirical studies on changes in oil governance

    Science.gov (United States)

    Kemal, Mohammad

    Regulation of the oil and gas sector is consequential to the economies of oil-producing countries. In the literature, there are two types of regulation: indirect regulation through taxes and tariffs or direct regulation through the creation of a National Oil Company (NOC). In the 1970s, many oil-producing countries nationalized their oil and gas sectors by creating and giving ownership rights of oil and gas resources to NOCs. In light of the success of Norway in regulating its oil and gas resources, over the past two decades several countries have changed their oil governance by changing the rights given to NOC from ownership right to mere access rights like other oil companies. However, empirical literature on these changes in oil governance is quite thin. Thus, this dissertation will explore three research questions to investigate empirically these changes in oil governance. First, I investigate empirically the impact of the changes in oil governance on aggregate domestic income. By employing a difference-in-difference method, I will show that a country which changed its oil governance increases its GDP per-capita by 10%. However, the impact is different for different types of political institution. Second, by observing the changes in oil governance in Indonesia , I explore the impact of the changes on learning-by-doing and learning spillover effect in offshore exploration drilling. By employing an econometric model which includes interaction terms between various experience variables and changes in an oil governance dummy, I will show that the change in oil governance in Indonesia enhances learning-by-doing by the rigs and learning spillover in a basin. Lastly, the impact of the changes in oil governance on expropriation risk and extraction path will be explored. By employing a difference-in-difference method, this essay will show that the changes in oil governance reduce expropriation and the impact of it is different for different sizes of resource stock.

    One major problem facing the commercial production of cellulosic ethanol is the challenge of economically harvesting and transporting sufficient amounts of biomass as a feedstock at biorefinery plant scales. Oil extraction for biodiesel production, however, yields large quantities of biomass co-products rich in cellulose, sugar and starch, which in many cases may be sufficient to produce enough ethanol to meet the alcohol demands of the transesterification process. Soybean, castor bean, Jatropha curcas, palm kernel, sunflower and cottonseed were studied to determine ethanol production potential from cellulose found in the oil extraction co-products and also their capacity to meet transesterification alcohol demands. All crops studied were capable of producing enough ethanol for biodiesel production and, in the case of cottonseed, 470% of the transesterification demand could be met with cellulosic ethanol production from oil extraction co-products. Based on Brazilian yields of the crops studied, palm biomass has the highest potential ethanol yield of 108 m{sup 3} km{sup -2} followed by J. curcas with 40 m{sup 3} km{sup -2}. A total of 3.5 hm{sup 3} could be produced from Brazilian soybean oil extraction co-products. (author)

    Marco Tulio Zanini

    2009-07-01

    Full Text Available It has been suggested that one of the negative aspects of the New Economy has been growing organizational survival-risk both at the firm and the sector levels. This precarious positioning of the firm has profoundly changed the work environment resulting in the dissolution of job-definition-boundaries, thereby raising the intensity of work and finally affecting the level and nature of trust in the workplace. This is the starting point for our study. Using a questionnaire developed by Gillespie, we investigated gender profiles concerning trust in Supervisors, Peers, and Team in the New and the Old Economies for Brazilian managers. The results show that, for the New Economy, Brazilian women are more willing to give trust to Supervisors whereas Brazilian men expressed higher levels of trust when dealing with Team members. The Peer results are mixed. For the Old Economy, men uniformly express higher levels of trust compared to women over all three reference groups. Finally, for gender matched comparisons, those working in the Brazilian Old Economy firms express higher levels of trust compared to their counterparts in the New Economy independent of gender or time worked. We conclude by discussing the control implications of the above results.

    Hydrogen is a promising energy carrier, which potentially could replace the fossil fuels used in the transportation and distributed energy sector of Brazilian economy. Fossil fuels are polluting by carbogenic emissions from their combustion, being so co-responsible for present global warming. However, no large scale, cost-effective, environmentally non-carbogenic hydrogen production process is currently available for commercialization. There are feasible possibilities to use electrolysis as one of the main sources of hydrogen, especially thinking on combination with renewable sources of energy, mainly eolic and solar. In this work some perspectives for Brazilian energy context is presented, where electrolysis combined with renewable power source and fuel cell power generation would be a good basis to improve the distributed energy supply for remote areas, where the electricity grid is not present or is deficient.

    In Brazil there is intense research activity in nanotechnology, most of these developed in universities and research institutes. The Brazilian Nanotechnology Initiative (BNI) aims to integrate government actions to promote the competitiveness of the Brazilian industry. This initiative is founded on support for research and development in the laboratories of the National Laboratories for Nanotechnology (SisNANO), starting from an improvement in infrastructure and opening of laboratories for users of academia and business, promoting interaction and transfer knowledge between academia and business. Country currently has 26 thematic networks of nanotechnology, 16 -Virtual-National Institutes of Technology, seven National- Laboratories and 18 Associate Laboratories, which comprise the SisNANO. Seeking to expand and share governance with other government actors, the Interministries Committee for Nanotechnology was set up, composed of 10 ministries, and has the task of coordinating the entire program of the Federal Government Nanotechnology.Cooperation activities are an important part of BNI. Currently Brazil has cooperation programs with U.S., China, Canada and European Union among others. Recently, Brazil decided to join the European NanoReg program where 60 research groups are joining efforts to provide protocols and standards that can help regulatory agencies and governments.

    The present paper discusses the enforcement of the antitrust law on oil and gas market. The importance of this theme refers to the open of oil and gas market after the constitutional amendment NBR. 09, by making the flexibilization of monopoly on oil and gas reservoirs and introducing the concurrence in this market. The amendment changed also the relationship between State and oil market by leaving the direct action on economy for indirect action and constituting a regulation authority, ANP. Thus, the paper studies the role of the Brazilian antitrust and regulation authorities in the defense of concurrence and the relationship between antitrust enforcement and regulation in the Brazilian oil market scenario.

    In many countries the residential sector accounts for about 20.0% of the electricity consumption, which increases the concern about energy savings. The main objective of this paper is to assess the impact of energy-efficient household appliances on the electricity consumption of the Brazilian residential sector by using electricity end-use data. The consumption of each appliance is obtained based on official data from existing studies, being estimated for a dwelling and for the whole residential sector. Results indicate that the potential for energy savings by replacing existing appliances with energy-efficient household appliances would be 29.5% in the residential sector of Brazil.

  3. Strategies for displacing oil

    2015-03-01

    Oil currently holds a monopoly on transportation fuels. Until recently biofuels were seen as the means to break this stranglehold. They will still have a part to play, but the lead role has been handed to natural gas, almost solely due to the increased availability of shale gas. The spread between oil and gas prices, unprecedented in its scale and duration, will cause a secular shift away from oil as a raw material. In the transport fuel sector, natural gas will gain traction first in the displacement of diesel fuel. Substantial innovation is occurring in the methods of producing liquid fuel from shale gas at the well site, in particular in the development of small scale distributed processes. In some cases, the financing of such small-scale plants may require new business models.

    Full Text Available Brazil is the 5th largest country in the world and its present population, in excess of 190 million, is highly heterogeneous, as a result of centuries of admixture between Amerindians, Europeans and Sub-Saharan Africans. The estimated individual proportions of biogeographical ancestry vary widely and continuously among Brazilians, most individuals - irrespective of self-identification as White, Brown or Black, the major categories of the Brazilian Census race/color system - having significant degrees of European and African ancestry, while a sizeable number display also Amerindian ancestry. These features have important pharmacogenetic (PGx implications: first, extrapolation of PGx data from relatively well-defined ethnic groups is clearly not applicable to the majority of Brazilians; second, the frequency distribution of polymorphisms in pharmacogenes (e.g. CYP3A5, CYP2C9, GSTM1, ABCB1, GSTM3, VKORC, etc varies continuously among Brazilians and is not captured by race/color self-identification; third, the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of PGx studies in order to avoid spurious conclusions based on improper matching of study cohorts. The peculiarities of PGx in Brazilians are illustrated with data for different therapeutic groups, such as anticoagulants, HIV-protease inhibitors and nonsteroidal antinflammatory drugs, and the challenges and advantages created by population admixture for the study and implementation of PGx are discussed. PGx data for Amerindian groups and Brazilian-born, first generation Japanese are presented to illustrate the rich diversity of the Brazilian population. Finally, I introduce the reader to the Brazilian Pharmacogenetic Network or Refargen (www.refargen.org.br, a nationwide consortium of research groups, with the mission to provide leadership in PGx research and education in Brazil, with a population health impact.

  5. Facts 2002. The Norwegian petroleum sector

    2002-07-01

    The petroleum sector is highly significant for the Norwegian economy. Its share of gross domestic product, exports and total government revenues has been substantial over the past two decades, reaching a particularly high level in 2000 and 2001. The principal reason why revenues were so high in these two years is a combination of high oil prices, a strong USD against the NOK and historically high petroleum production. The share of petroleum investment in total capital spending in the Norwegian economy was at its highest in the early 1990s. Total investment in the petroleum sector has been above NOK 40 bn every year since 1992, and peaked in 1998 at roughly NOK 80 bn. Capital spending declined to around NOK 56.9 bn in 2001. The government's most important revenue sources in recent years have been cash flow from the state's direct financial interest (SDFI) and from taxes. Production of crude oil has averaged around three mill barrels per day since 1996. The figure for 2001 was 3.1 mill barrels. Including natural gas liquids (NGL) and condensate raises the 2001 average to 3.4 mill barrels oe per day. At 53 mill scm oe, gas production was also high in 2001. Oil production is expected to remain more or less unchanged over the next few years, and then to go into a gradual decline. Gas output, on the other hand, should expand substantially over the coming decade and is expected to be increasingly significant in Norwegian petroleum output in future. The petroleum sector is also a substantial player internationally. Norway ranks as the world's sixth largest producer and third largest net exporter of oil. It is also the world's third largest exporter of pipeline gas, and Norwegian foreign sales of this commodity accounted for about two per cent of global consumption in 2001. Roughly 10 per cent of west European gas consumption is covered from Norway. Several changes were made to state participation in the petroleum sector during 2001. The government sold

    A space weather program is being initiated at the Brazilian National Institute for Space Research (INPE) to study events from their initiation on the sun to their impacts on the earth, including their effects on space-based and ground-based technological systems. The program is built on existing capabilities at INPE, which include scientists with a long tradition and excellence in the observation, analysis and modeling of solar and solar-terrestrial phenomena and an array of geophysical instruments that spans all over the Brazilian territory from the north to south of the magnetic dip equator. Available sensors include solar radio frequency receivers and telescopes, optical instruments and solar imagers, GNSS receivers, ionosondes, radars, allsky imagers, magnetometers and cosmic ray detectors. In the equatorial region, ionosphere and thermosphere constitute a coupled system with electrodynamical and plasma physical processes being responsible for a variety of peculiar phenomena. The most important of them are the equatorial electrojet current system and its instabilities, the equatorial ionization anomaly, and the plasma instabilities/irregularities of the night-time ionosphere (associated with the plasma bubble events). In addition, space weather events modify the equatorial ionosphere in a complex and up to now unpredictable manner. Consequently, a main focus of the program will be on monitoring the low, middle and upper atmosphere phenomena and developing a predictive model of the equatorial ionosphere through data assimilation, that could help to mitigate against the deleterious effects on radio communications and navigation systems. The technological, economic and social importance of such activities was recognized by the Brazilian government and a proposal for funding was approved for the period 2008-2011. New ground instruments will be installed during this period allowing us to extend our current capability to provide space weather observations, accurate

    Full Text Available The theme of corporate social responsibility (CSR has not been widely examined in the context of multinationals. This dearth is even greater with respect to subsidiaries, particularly the subject of reverse transfer of practices, that is, the transfer of practices developed in subsidiaries back to the parent company. Because of this theoretical gap, the present article investigates the factors involved on reverse transfer of CSR practices. The research hypotheses test the importance of developing nonlocation-bound capabilities, of integration between subsidiaries and parent and of institutional distance. The data were obtained by a survey of the main foreign subsidiaries in Brazil. All told, we analyzed 150 Brazilian subsidiaries of multinationals, by applying multiple linear regression. The results indicate that the reverse transfer of CSR depends on the development of nonlocation-bound capabilities of the subsidiaries and integration between the parent company and its foreign subsidiaries.

    The objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

    2010-04-01

    The purpose of this article is to present a quantitative analysis of the human failure contribution in the collision and/or grounding of oil tankers, considering the recommendation of the "Guidelines for Formal Safety Assessment" of the International Maritime Organization. Initially, the employed methodology is presented, emphasizing the use of the technique for human error prediction to reach the desired objective. Later, this methodology is applied to a ship operating on the Brazilian coast and, thereafter, the procedure to isolate the human actions with the greatest potential to reduce the risk of an accident is described. Finally, the management and organizational factors presented in the "International Safety Management Code" are associated with these selected actions. Therefore, an operator will be able to decide where to work in order to obtain an effective reduction in the probability of accidents. Even though this study does not present a new methodology, it can be considered as a reference in the human reliability analysis for the maritime industry, which, in spite of having some guides for risk analysis, has few studies related to human reliability effectively applied to the sector.

  8. Searching for Dark Sectors

    Science.gov (United States)

    Zhong, Yi-Ming

    The existence of Dark Matter suggests the presence of a dark sector, consisting of particles neutral under all Standard Model forces. Various "portals" can connect the dark sector to the Standard Model sector. Two popular examples are the vector portal, which gives rise to a "dark photon" ( A'), and the Higgs portal, which gives rise to a "dark Higgs". Such dark forces appear in many well-motivated extensions of the Standard Model. In some cases, they may resolve discrepancies between experimental data and theoretical predictions, such as the muon anomalous magnetic moment. We show that dark sectors and forces can be constrained from several novel probes in current and future experiments, including mono- photon searches in low-energy positron-electron colliders, rare muon decays in the Mu3e, and exotic Higgs decays at the Large Hadron Collider (LHC). We first investigate the power of low-energy, high-luminosity electron-positron colliders to probe dark sectors with a mass below 10 GeV, which couple to Standard Model particles through a low-mass dark mediator. Dark matter candidates in this mass range are well- motivated and can give rise to distinctive mono-photon signals at B-factories and similar experiments. We use data from an existing mono-photon search by BABAR to place new constraints on this class of models, and give projections for the sensitivity of a similar search at a future B-factory such as Belle II. We find that the sensitivity of such searches are more powerful than searches at other collider or fixed-target facilities for dark-sector mediators and particles with masses between a few hundred MeV and 10 GeV. We compare our results to existing and future direct detection experiments and show that low-energy colliders provide an indispensable and complementary avenue to search for light dark matter. We also find that dark photons with masses 10 MeV - 80 MeV can probed in the rare muon decay process mu+→ e+nue numuA', A '→ e+ e-, in the upcoming Mu

    1980-12-01

    Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

These models are characterized by only two free parameters, namely the typical coupling g{sub D} and the scale f{sub D} of the composite sector, and are therefore very predictive. We consider in detail two minimal scenarios, SU(3)/[SU(2)×U(1)] and [SU(2){sup 2}×U(1)]/[SU(2)×U(1)], which provide a dynamical realization of the Inert Doublet and Triplet models, respectively. We show that the radiatively-induced potential can be computed in a five-dimensional description with modified boundary conditions with respect to Composite Higgs models. Finally, the dark matter candidates are shown to be compatible, in a large region of the parameter space, with current bounds from dark matter searches as well as electroweak and collider constraints on new resonances.

    In recent years successive Brazilian governments have actively pursued economic and social policies aimed at reducing poverty and promoting social equality and inclusion. In the field of energy, this has meant introducing and implementing programs aimed at expanding the supply of safe and reliable energy to the poorest sectors of Brazilian society, including those living in remote rural areas. This paper draws attention on the findings of extensive field research to evaluate the impact of rural electrification on energy poverty in the context of government policies aimed at promoting energy equity. The authors re-examine the concept of an energy poverty line, seeking to fine tune its application to Brazilian social and economic realities, and then apply an analytical framework (Lorenz Curve, Gap Poverty, Gap Quadratic, Gini Coefficient and Sen Index) to evaluate the effectiveness of recent efforts in Brazil to expand access to electricity. One of the main conclusions of this study is that is that rural electrification leads to a significant reduction of the energy poverty level and a consequent improvement in energy equity. (author)

  1. Economic and social characteristics of the Brazilian population.

    Science.gov (United States)

    Sanders, T G

    1982-01-01

    The question of whether Brazilians have improved their economic situation since 1970 is controversial. A number of questions on the Brazilian census of 1980 dealt with the economic and social characteristics of the population. The usefulness of census data lies in their capacity to indicate trends every 10 years. Consequently, one can get some idea of whether Brazil is making progress in certain aspects of modernization or in improving the skills and living conditions of the people. Census data have limitations. They indicate averages, not specific cases. They fail to raise a number of questions about economic and social conditions that would improve understanding. Discussion is focused on population structure and the economy, income, housing, education, and health. Brazil is continuing the process of modernization by which population shifts from the primary sector (agriculture and mining) into other sectors of the economy. The 14.88% of the work force in agriculture, livestock, and fishing represent about 30% of the potentially economically active (PEA) population. 1/3 of the population is still rural, but the trend since 1940 is striking. The momentum of decline intensified in both 1960-70 and 1970-80, reflecting a process of abandoning small farms, mechanizing larger farms, and a general flow of population to the cities. All other sectors of the economy have increased the proportion of people working in them. The data of 1980 reflect a period of sustained economic growth that culminated in that year with an increase of 8%. In 1981 and 1982, Brazil had been in a recession so that in 1983 some of these figures might have changed. The dispute began when the results of the 1970 census were used to show that income was becoming more concentrated, i.e., the top percentages, in comparison with 1960, received a larger share of national income, while the lowest percentages received less. The differences in income between men and women is particularly strong in the

    Petroleum exploration in the Paleozoic sedimentary basins of Brazil has proven very challenging for explorationists. Except for the Solimoes Basin, in which transcurrent tectonism formed prospective structural highs, Brazilian Paleozoic basins lack intense structural deformation, and hence the detection and prospecting of place is often difficult. Magmatic intrusive and associated rocks in all these basins have traditionally been considered heat sources and hydrocarbon traps. The role of tholeiitic basic dikes in the generation, migration and accumulation of petroleum in the Anhembi oil occurrence (Sao Paulo State) is discussed herein. It follows that similar geological settings in other Paleozoic basins can be regarded as promising sites for oil accumulation that warrant investigation via modern geological and geophysical methods.

    Aquaculture has many occupational hazards, including those that are physical, chemical, biological, ergonomic, and mechanical. The risks in aquaculture are inherent, as this activity requires particular practices. The objective of the present study was to show the risks associated with the aquaculture sector and present a critical overview on the Brazilian public policies concerning aquaculture occupational health. Methods include online research involved web searches and electronic databases including Pubmed, Google Scholar, Scielo and government databases. We conducted a careful revision of Brazilian labor laws related to occupational health and safety, rural workers, and aquaculture. The results and conclusion support the idea that aquaculture requires specific and well-established industry programs and policies, especially in developing countries. Aquaculture still lacks scientific research, strategies, laws, and public policies to boost the sector with regard to occupational health and safety. The establishment of a safe workplace in aquaculture in developing countries remains a challenge for all involved in employer-employee relationships.

    Full Text Available This article analyzes the effectiveness of hedging Brazilian soy oil, soy meal, and soybeans in the Chicago Board of Trade (CBOT and in the Brazilian Commodities and Futures Exchange (BM&F to reduce the risk of financial loss due to commodity price fluctuations. The econometric results show that a cross-hedging strategy using the BM&F soybean futures contract is an instrument of low effectiveness for managing soy oil and soy meal price risk. Despite low effectiveness, the estimates demonstrate total advantage for soy meal hedging operations using CBOT soy meal futures contracts rather than cross-hedging using BM&F soybean futures contracts. With some exceptions, the results are also more favorable for hedging soy oil with soy oil futures contracts at the CBOT rather than cross hedging with soybeans at the BM&F. Conversely, Brazilian traders hedging soybeans receive more effective risk protection by trading soybean futures contracts at the BM&F than by trading soybean futures contracts at the CBOT.

Em termos empíricos, foram analisados os dados financeiros de empresas brasileiras dos setores de energia elétrica e telecomunicações que apresentaram aumento de ativo permanente igual ou superior a 75% em determinado momento entre 1996 e 2005, a fim de avaliar a evolução da estrutura de capital. A metodologia consistiu essencialmente na utilização de testes não-paramétricos de Mann-Whitney com o objetivo de comparar e analisar a estrutura de capital das empresas em momentos anteriores e posteriores à realização de grandes investimentos. Os resultados encontrados permitiram concluir que, mesmo mediante forte aumento na estrutura de ativos, a estrutura de capital das empresas do setor de energia elétrica foi afetada apenas no médio e longo prazos. Por outro lado, no setor de telecomunicações, ela não foi afetada até dois anos após o aumento realizado nos ativos permanentes. A análise de histórias específicas de empresas da amostra revelaram que suas especificidades exercem um papel crucial sobre a escolha da estrutura de capital, superando até mesmo os efeitos provocados por características setoriais.

    Oil shales are fine-grained sedimentary rocks formed in many different depositional environments (terrestrial, lacustrine, marine) containing large quantities of thermally immature organic matter in the forms of kerogen and bitumen. If defined from an economic standpoint, a rock containing a sufficient concentration of oil-prone kerogen to generate economic quantities of synthetic crude oil upon heating to high temperatures (350–600 °C) in the absence of oxygen (pyrolysis) can be considered an oil shale.

    2006-08-01

    Full Text Available Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and 4 in the ISI-Thompson base of different medical specialties were analyzed, and the number of both Portuguese and English citations in the reference list of each article was recorded. The results showed that in Brazilian-edited journals the mean number of citations/article was 20.9 ± 6.9 and the percentage of citations of international non-Brazilian periodicals was 86.0 ± 11.2%. Of the latter, 94.4 ± 7.0 are indexed by ISI-Thompson. Therefore, we conclude that Brazilian medical scientists cite the international non-Brazilian periodicals more than the national journals, and most of the cited papers are indexed by ISI-Thompson.

    2007-06-01

    Full Text Available The paper points to recent developments in the tourism sector and highlights the leading factors of the internationalization of tourists travel and of tourism services, including information technologies, as well as the internationalization of hotel and tourism enterprises. Without neglecting the huge subsector of small and medium-sized enterprises, it describes typical features related to the composition of the labour force and to working conditions. It raises questions concerning the difficulties faced by the sector in attracting and retaining skilled workers in enhancing the skills of newcomers to the labour market in order to stabilize the sector’s labour force, while increasing the productivity of enterprises and the quality of services. Particular emphasis is put on new forms of management entailing new skills requirements, with a general tendency towards increased worker responsibility in an environment of flat hierarchies, multiskilling and teamwork.

  10. Coal sector profile

    Energy Technology Data Exchange (ETDEWEB)

    1990-06-05

    Coal is our largest domestic energy resource with recoverable reserves estimated at 268 billion short tons or 5.896 quads Btu equivalent. This is approximately 95 percent of US fossil energy resources. It is relatively inexpensive to mine, and on a per Btu basis it is generally much less costly to produce than other energy sources. Its chief drawbacks are the environmental, health and safety concerns that must be addressed in its production and consumption. Historically, coal has played a major role in US energy markets. Coal fueled the railroads, heated the homes, powered the factories. and provided the raw materials for steel-making. In 1920, coal supplied over three times the amount of energy of oil, gas, and hydro combined. From 1920 until the mid 1970s, coal production remained fairly constant at 400 to 600 million short tons a year. Rapid increases in overall energy demands, which began during and after World War II were mostly met by oil and gas. By the mid 1940s, coal represented only half of total energy consumption in the US. In fact, post-war coal production, which had risen in support of the war effort and the postwar Marshall plan, decreased approximately 25 percent between 1945 and 1960. Coal demand in the post-war era up until the 1970s was characterized by increasing coal use by the electric utilities but decreasing coal use in many other markets (e.g., rail transportation). The oil price shocks of the 1970s, combined with natural gas shortages and problems with nuclear power, returned coal to a position of prominence. The greatly expanded use of coal was seen as a key building block in US energy strategies of the 1970s. Coal production increased from 613 million short tons per year in 1970 to 950 million short tons in 1988, up over 50 percent.

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

    believe that structural change is an unimportant side effect of the economic development. On the contrary, economists associated with the World Bank and some others posit that growth is brought about by the changes in sectoral composition. The objective of this study is to empirically test...... the relationship between sectoral shares and economic growth by using the panel data for 20 developed countries. The results of the granger causality suggest that both services and agriculture sectors do granger cause economic growth, whereas industrial sector does not granger cause growth. Reverse causality does...... not hold for any of the three sectors. The results of Barro and Non-Barro regressions along with the set of control variables have suggested that services sector is negatively affecting growth, whereas both industrial and agriculture shares are positively affect economic growth....

    Full Text Available Detrás de su aparente heterogeneidad, las distintas teorías sobre el sector y la empresa informal tienen en común importantes presupuestos epistemológicos y metodológicos. Esto se debe a que todos los teóricos de la informalidad han ido a llenar sus cántaros conceptuales a una misma y única fuente: la noción de informalidad propuesta originalmente por Keith Hart (1971 en los años setenta. Pero cuando hicieron suya la -noción de informalidad, los seguidores de Hart no pudieron despojarla nunca de las inconsistencias teóricas que le eran inherentes desde su origen, a pesar de haberla traducido y reformulado en el lenguaje propio de sus respectivas escuelas de pensamiento.

    2010-08-01

    Full Text Available The present work deals with the Brazilian exports of sawnwood of non-coniferous, veneer sheets and plywood, from 1961 to 2002. The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

    Full Text Available The antileishmanial and immunomodulatory effects of propolis collected in Botucatu, São Paulo State, Brazil, were evaluated in Leishmania (Viannia braziliensis experimental infection. The antileishmanial effect of propolis on promastigote forms was verified by reducing growth and by promoting morphologic alterations observed by scanning electron microscopy. In in vitro immunomodulatory assays, macrophages were pretreated with propolis and then infected with L. (V. braziliensis. In vivo, supernatants from liver cells and peritoneal exudate of BALB/c mice pretreated with propolis and infected with Leishmania (107/mL promastigotes were collected, and TNF-α and IL-12 were measured by ELISA. Macrophages incubated with propolis showed a significant increase in interiorization and further killing of parasites. An increased TNF-α production was seen in mice pretreated with propolis, whereas IL-12 was downregulated during the infection. In conclusion, Brazilian propolis showed a direct action on the parasite and displayed immunomodulatory effects on murine macrophages, even though the parasite has been reported to affect the activation pathways of the cell. The observed effects could be associated with the presence of phenolic compounds (flavonoids, aromatic acids, and benzopyranes, di- and triterpenes, and essential oils found in our propolis sample.

    In this paper, the effects of a minor sudden stratospheric warming (SSW) event of 2012 in the ionosphere over South American and African sectors have been studied using C/NOFS satellite data and GPS observations. Also, the magnetometer measurements obtained at two stations in the equatorial and low-latitude regions in the South American sector are presented. There were significant Vertical Total Electron Content (VTEC) depletions in the afternoon in both South American and African sectors during the 2012 minor SSW event. A novel feature of the present study is the reduction of the quasi 16-day oscillation (periods ranging from 11 to 20 days) in the daily averaged VTEC in the Brazilian and African sector during an SSW event. Also, the results for the Brazilian sector show an amplification of the 2-6 day period in the daily averaged VTEC at equatorial and low-latitude regions, after the SSW temperature peak. This investigation shows that a minor SSW can affect the irregularities at ionospheric heights in the Brazilian and African sectors. Ground-based magnetometer measurements in the American sector shows strongly enhanced equatorial electrojet (EEJ) after the SSW temperature peak.

    The history of oil shale development was examined by gathering relevant research literature for an Unconventional Oil Resource Repository. This repository contains over 17,000 entries from over 1,000 different sources. The development of oil shale has been hindered by a number of factors. These technical, political, and economic factors have brought about R&D boom-bust cycles. It is not surprising that these cycles are strongly correlated to market crude oil prices. However, it may be possible to influence some of the other factors through a sustained, yet measured, approach to R&D in both the public and private sectors.

  6. Human rights in the energy sector: where are we going?

    Wright, Jim [KBC Advanced Technologies, Surrey (United Kingdom)

    2012-07-01

    There is considerable guidance and tools to avoid and remediate adverse Human Rights impacts; Environmental Impact Assessment (EIA), specific Human Right Impact Assessments or stand alone assessments across the whole spectrum of Human Rights. However the oil and gas sector has yet to address Human Rights risks in a comprehensive manner. In 2011 the Special Representative of the Secretary-General issued Guiding Principles (GP) to implement the United Nations 'Protect, Respect and Remedy' Framework. A survey of Human Rights performance against GP16 by the largest International Oil Companies (IOCs) and National Oil Companies (NOCs) shows a dichotomy with most (93%) of IOCs having a Human Rights Policy, approved at the highest level and available via the www to the general public (compliant with GP16) whilst 27% of NOCs have a Policy, of which, 9% are GP16 compliant. When service companies are included, only 23% are GP16 compliant. Only 8% provide Human Rights training. Human Rights in 41% of new projects are assessed via an EIA process, 18% via a specific Human Rights process, and 41% do not focus on Human Rights at all. Most companies do not have a Human Rights grievance mechanism. Whilst the IOCs are performing well the rest of the oil and gas sector, including the NOCs and service companies, are under-performing. The apparent reliance on the EIA process to Protect, Respect and Remedy Human Rights may be inadequate as the delivery of EIA is: still heavily biased toward environment compared to social and health impacts; they are time consuming and the Human Rights landscape can change during the EIA process; and the EIA disclosure process may expose vulnerable people to abuse. The oil and gas sector needs to address the record of poor compliance and develop and integrate some of the widely available Human rights tools. (author)

    This presentation discusses the technology and experience of Petrobras in the development of deep-water exploitation off the coast of Brazil. The company recently found important oil deposits in waters over 300 m deep in Campos Basin, the main petroleum province in Brazil, located offshore Rio de Janeiro State. It is estimated that 50% of the new discoveries will take place in waters deeper than 1000 m. Unlike other companies, Petrobras made an option to develop its offshore fields by means of sub-sea equipment and floating production units. This was possible mainly because of the characteristics of the reservoirs and the mild environmental conditions in Campos Basin. Petrobras has 288 subsea trees on the seabed, 48 subsea manifolds and 21 floating production units in operation. The company has constantly moved on to deeper and deeper waters and by the end of 1998 a new milestone will be achieved with a Roncador field subsea well at 1853 m. Procap-2000, a strategic research and development corporate programme for ultra-deep water technology, was developed. Other innovations by Petrobras are also discussed. 3 figs.

    2002-07-01

    The Ministry of Petroleum and Energy produces an annual environmental review in cooperation with the Norwegian Petroleum Directorate. The purpose of this publication is threefold: (1) to increase knowledge about the environmental aspects of Norwegian oil and gas activities, (2) to take a more detailed look at a specific topic which particularly concerns both the industry and the authorities, and identify the challenges and options faced, (3) to emphasise the governments goal of ensuring that Norway reconciles its role as a large energy producer with a pioneering position on environmental issues. This year's edition focuses on the topic of ''oil and fish - common sea''. Both the petroleum and fishing industries depend on the waters off Norway. Ever since petroleum activities began on the Norwegian continental shelf more than 30 years ago, the authorities have been keen to ensure that these two sectors can work in the same sea areas. What challenges and opportunities face the petroleum industry over discharges to the sea and living marine resources? How can the authorities ensure that this sector is able to coexist with the fisheries? These and similar questions about the relationship between the petroleum and fishing industries in their shared seas are covered in section two of this publication. Environment 2002 also incorporates a factual section, which covers the status of emissions/discharges, environmental impacts and measures to reduce discharges to the sea and emissions to the air from petroleum activities. The MPE hopes that a publication of this kind can enhance basic knowledge about petroleum activities and environmental issues.

Therefore, we use the constant market share analysis to compare several countries’ export performance. It was observed that Asian countries emerged strengthened from this period. Brazil had a mediocre performance, losing market-share in global markets. Moreover, competition from Asian economies and even from the small Central American countries, such as Guatemala and El Salvador, has undermined the penetration of Brazilian exports in its major trade partners, which are North America and South America.

This is close to two million barrels per day, placing the country among the major oil producers in the world. At the same time, Angola shares the characteristics of so-called Least Developed Countries and faces serious structural challenges. At present there are at least three threats targeting Angolan external sector, namely the high propensity to import, the volatility of oil prices and the slowdown in the Chinese economy.

    Energy Technology Data Exchange (ETDEWEB)

    Wu, Kang; Pezeshki, S.; McMahon, J.

    1995-08-01

    In recent years, Latin America`s hydrocarbons sector has been characterized by reorganization, revitalization, regional cooperation, environmental awakening, and steady expansion. The pattern of these changes, which appear to be the megatrends of the region`s hydrocarbons sector development, will continue during the rest of the 1990s. To further study the current situation and future prospects of Latin America`s hydrocarbons sector, we critically summarize in this short article the key issues in the region`s oil and gas development. These megatrends in Latin America`s hydrocarbons sector development will impact not only the future energy demand and supply in the region, but also global oil flows in the North American market and across the Pacific Ocean. Each country is individually discussed; pipelines to be constructed are discussed also.

  6. Oil palm seed distribution

    Directory of Open Access Journals (Sweden)

    Durand-Gasselin Tristan

    2005-03-01

    Full Text Available For a tropical plant, the oil palm commodity chain has the peculiarity of possessing a major seed production sector for reasons that are primarily genetic. This seed sector has numerous original aspects. Breeders are also propagators and usually also distribute their seeds. Oil palm seeds are semi-recalcitrant: they display pseudo-dormancy. Achieving seed germination is difficult and requires lengthy treatments and special installations. This restriction greatly influences seed distribution and the role of the different stakeholders in the commodity chain. It was only once it had been discovered how the “sh” gene functioned, which controls shell thickness, and when it became necessary to produce “tenera” seeds derived from exclusively “dura x pisifera” crosses, that a true seed market developed. In addition it is difficult to organize seed distribution to smallholders. This is partly due to difficulties that the profession, or a State-run organization, has in controlling middlemen networks, and partly to the absence of any protective systems (UPOV, plant breeder certificate, etc. that generally oblige breeders to preserve and propagate parents in their own installations. In fact there are major inequalities in the access to seeds between agroindustry and smallholders. Another peculiarity of the oil palm seed market is the virtually total absence of guarantees for buyers: the quality of the research conducted by breeders, the seed production strategies necessary for transferring genetic progress, and the technical quality of production. The only guarantee today comes from the relations of confidence established year after year between breeders/distributors and growers. In this fields, research can lead to some proposals: molecular biology offers some interesting prospects for certifying seed quality and social science develop effective communication methods.

  7. Retention of key employees in the oil field service sector

    Lee, S.

    1999-07-01

    Before 1994, Core Laboratories Canada Ltd. adopted local country benefit plans as stipulated by the government of the day. This approach meant that the company had many different benefit plans in place or in some situations no benefit plans at all, if the law of the land allowed such an approach. The company at this time viewed the lack of or minimal benefit plans as a cost saving venture. The parent company did not take onto account the effect on morale, employee retention and loyalty that these limited plans provided. A change in ownership in 1994 presented the opportunity for Core to re-assess its benefits package and introduce an incentive plan for its worldwide employees. The introduction of a pension with profits plan proved to be satisfying to employees, and the manager's incentive plan enabled the company to retain, with the exception of people who retired from the business, its entire management staff over a four year period. The stock option plan led to the retention of essential employees and reduced the turnover in this area. Discretionary bonuses succeeded in promoting recognition amongst employees as well as providing monetary reward, and the combination of benefits, incentive and stock option plans enabled the company to retain the vast majority of key employees and to entice selected individuals to the company from other organizations. 3 refs.

    The essential oils of Hyptis suaveolens plants collected from 11 localities of the Brazilian Cerrado region were investigated by GC-MS. Sabinene, limonene, biclyclogermacrene, beta-phellandrene and 1,8-cineole were the principal constituents. The results were submitted to principal component and chemometric cluster analysis which allowed three groups of essential oils to be distinguished with respect to the content of p-mentha-2,4(8)-diene, limonene/beta-phellandrene/gamma-terpinene and germacrene D/bicyclogermacrene. In patterns of geographic variation in essential oil composition indicated that the sesquiterpenes are mainly produced in the samples grown at lower latitudes.

  13. Passages on Brazilian scientific cinema.

    de Almeida, Jane; da Silva, Cicero Inacio; Suppia, Alfredo; Stalbaum, Brett

    2017-07-01

    The article examines the conditions of production and recognition of scientific cinema in Brazil by comparing three distinct moments and contexts: the first moment takes place in the nineteenth century, and it is related to the contribution of a Brazilian astronomer otherwise little known to Brazilian film scholars, the second addresses Benedito Junqueira Duarte's voluminous mid-twentieth-century filmography, and the third moment documents recent scientific film experiences within ultra high resolution movies transmitted over photonic networks. Future trajectories for aesthetic concerns and practical issues such as the archiving of ultra high definition cinema are usefully informed by these histories of scientific cinema, even as a current generation of multidisciplinary teams including scientists, filmmakers, computer scientists, and network engineers reinvent, rediscover, and necessarily expand the scientific cinema toward concerns of real time collaboration and teaching.

  17. Brazilian Studies Then and Now

    Directory of Open Access Journals (Sweden)

    Full Text Available In 1912 the Brazilian diplomat and scholar Manuel de Oliveira Lima gave six lectures at Stanford University that encapsulated his views of what we now call Brazilian Studies. This article summarizes Oliveira Lima’s lectures. It then points out three aspects of Oliveira Lima’s worldview that are problematic from the perspective of the twenty-first century: his Eurocentrism; the unproblematic nature of the nation-state in his thinking; and his largely negative view of Brazil’s racial heritage. The third part of the essay analyzes three aspects of Oliveira Lima’s lectures that are still contemporary. These are the need to establish an adequate comparative context for the study of Brazil; the difficulty of justifying an academic discipline that revolves around the study of a single country; and the challenge of uniting disparate and specialized disciplines in order to appreciate Brazil’s complexity and trajectory in the modern world. In the conclusion, some guidelines for maintaining Brazilian Studies as a vibrant field are suggested.

    Full Text Available Crude oil is an important energy commodity to mankind. Several causes have made crude oil prices to be volatile. The fluctuation of crude oil prices has affected many related sectors and stock market indices. Hence, forecasting the crude oil prices is essential to avoid the future prices of the non-renewable natural resources to rise. In this study, daily crude oil prices data was obtained from WTI dated 2 January to 29 May 2015. We used Markov Model (MM approach in forecasting the crude oil prices. In this study, the analyses were done using EViews and Maple software where the potential of this software in forecasting daily crude oil prices time series data was explored. Based on the study, we concluded that MM model is able to produce accurate forecast based on a description of history patterns in crude oil prices.

    The Brazilian Nuclear Agency (CNEN) rules all nuclear activity in Brazil as demanded by the Federal Constitution, articles 21, XXIII, and 177, V, and by the Federal Acts 4.118/62 and 10.308/2001. Therefore, the CNEN is responsible for any radioactive waste disposal in the country. Oil Naturally Occurring Radioactive Materials (Oil NORM) in this paper refers to waste coming from oil exploration. Oil NORM has called much attention during the last decades, mostly because it is not possible to determine its primary source due to the actual absence of regulatory control mechanism. There is no efficient regulatory tool which allows determining the origin of such NORM wastes even among those facilities under regulatory control. This fact may encourage non-authorized radioactive material transportation, smuggling and terrorism. The aim of this project is to provide a geochemical signature for each oil NORM waste using its naturally occurring isotopic composition to identify its origin. The here proposed method is a specific geochemical modeling of oil sludge NORM samples which are analyzed for radioisotopes normally present in oil pipes, such as {sup 228}Ac, {sup 214}Bi and {sup 214}Pb. The activity ratios are plotted in scatter diagrams. This method was successfully tested with data of different sources obtained from analysis reports from the Campos Basin/Brazil and from literature. (author)
