  1. Competitiveness in the Brazilian oil industry. The Brazilian 'oil diamond'

    International Nuclear Information System (INIS)

    It is recognized the economic benefits that might follow the opening process of the Brazilian oil and natural gas industry, which shall experience a fast expansion with the arrival of national and international private investors. However, we should not neglect the broader impact of this process on the future development of all that cluster of national agents that lived around and served the former national oil monopoly, managed by the Brazilian National Oil Company, Petrobras. This work focuses on this larger perspective, discussing about the capacity of Brazil to sustain and expand its competitiveness in the oil business as well as to obtain the maximum economic development from the exploration of its oil and gas reserves. We adopt the work of Michael Porter, from the University of Harvard, about the Competitive Advantage of Nations, as a theoretical model to analyze the Competitive Advantage of Brazil in the global oil industry. By introducing the concept of ''oil diamond'', adapted from the notion introduced by this author, we develop a new understanding of national competitiveness in the oil sector. In this paper, we present the general model as well as a brief characterization of the results found for Brazil Subsequently, we focus on just one leg of the model, for which we discuss, with more detail, about the competitive condition of the country in the opening-up scenario. This leg regards the so-called supporting and supplementary industries that constitute what is denominated in the French tradition the ''para petroleum'' industry. We analyze the conditions for the Brazilian domestic ''para petroleum industry'' to survive and grow in the new competitive environment. (authors)

    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)

    Full Text Available This study seeks to understand the competitive pattern and strategy of the firms in the Brazilian automobile financing market. First, we analyzed the strong segmentation observed in this market, determining market niches. We then estimated reaction functions to price changes. The results indicated that the three largest companies in the sector have a strong influence on interest rate setting within the entire segment. This phenomenon characterizes the competition of this sector as the leader-follower type, rather than Bertrand competition, the latter of which is often expected in the banking sector and it demonstrates the existence of the leading firms' market power.

  8. The stochastic effects on the Brazilian Electrical Sector

    International Nuclear Information System (INIS)

    The size and characteristics of the Brazilian Electrical Sector (BES) are unique. The system includes a large-scale hydrothermal power system with many hydroelectric plants and multiple owners. Due to the historical harnessing of natural resources, the National Interconnected System (NIS) was developed outside of the economic scale of the BES. The central components of the NIS enable energy generated in any part of Brazil to be consumed in distant regions, considering certain technical configurations. This interconnection results in a large-scale complex system and is controlled by robust computational models, used to support the planning and operation of the NIS. This study presents a different vision of the SEB, demonstrating the intrinsic relationship between hydrological stochasticity and the activities executed by the system, which is an important sector of the infrastructure in Brazil. The simulation of energy scenarios is crucial to the optimal manner to operate the sector and to supporting decisions about whether expansion is necessary, thus, avoiding unnecessary costs and/or losses. These scenarios are an imposing factor in the determination of the spot cost of electrical energy, given that the simulated quantities of water in the reservoirs are one of the determinants for the short-term energy price. - Highlights: • The relationship between the hydrological regimes and the energy policy and planning in Brazil; • An overview about the stochastic effects on the Brazilian Electrical Sector; • The stochasticity associated with the Brazilian electrical planning; • The importance of hydro resources management for energy generation in Brazil;

    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.

    International Nuclear Information System (INIS)

    A global oil and oil product prices evolution model is proposed that covers the transformation sector incidence and the final user price establishment together with price interactions between gaseous and liquid hydrocarbons. High disparities among oil product prices in the various consumer zones (North America, Western Europe, Japan) are well described and compared with the low differences between oil supply prices in these zones. Final user price fluctuations are shown to be induced by transformation differences and competition; natural gas market is also modelled

  18. Understanding organization and institutional changes for management of environmental affairs in the Brazilian petroleum sector

    International Nuclear Information System (INIS)

    This article analyzes how governments and an oil company adapted their institutional and organization frameworks to manage actual and potential environmental impacts of oil-related activities in Brazil. Two major factors are important for understanding these changes. First, the monopoly of the state to explore and produce oil is over. Foreign companies have entered Brazil and increased the competitiveness of the oil sector. Second, major oil spills into waterways in recent years resulted in severe fines and an increasing outcry from government and civil society representatives for greater control over oil activities. These two factors raised a debate about what are, or should be, the roles of various stakeholders involved in controlling oil activities and their impacts on the environment. Legislative changes assigned different roles to the state oil company, to a newly created regulatory agency, to the Navy and to federal and state environmental agencies. Because many of the legal changes were not well defined, accountability among institutional actors remained unclear and institutional conflicts about who is accountable for what were likely to occur. As well, government organizations, public prosecutors, media and civil society increasingly influenced the regulation of both government agencies and companies. As a result, these responded to regulatory change and market forces by changing their relations with external stakeholders and their organizational arrangements for environmental management. This article identifies some of the institutional conflicts in selected case studies from the oil industry, the difficulties in clarifying regulatory roles within the industry, and responses in terms of the environmental strategies of regulatory bodies and oil companies, specifically the Brazilian state company, Petrobas.

    Due to Brazil is a tropical country has activities in occupational exposure to cold restricted to few sectors especially the meatpacking industry. Taking into account that the country in 2010, was again the largest exporter of poultry meat in the world and consequently employing a large number of workers for their slaughter and processing. The search for greater productivity can result in an increase in work rate, as indicated in this sector as monotonous, repetitive and uncomfortable. According the Programa de Frigorífico it was found that within six years, about 20% of the six thousand workers in a slaughterhouse in southern Brazil, received welfare benefits due to musculoskeletal diseases. Adding to this, the lack of parameters for the Brazilian standardization concerning occupational activities carried out in cold. Although several epidemiological studies point to the cold as a risk factor for occurrence or aggravation of musculoskeletal disorders, research in this field is still limited and often contradictory conclusions. This article aims to review developments concerning the poultry industry and the fridge in Brazil, as well as raising the question about the increased productivity of the slaughterhouse, since it has already shown a high prevalence of musculoskeletal disorders related to work.

    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.

    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.

  3. Renewable and non-renewable exergy costs and CO2 emissions in the production of fuels for Brazilian transportation sector

    International Nuclear Information System (INIS)

    An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the percentage distribution of exergy destruction in the different units of the processing plants is characterized. An exergoeconomy methodology is developed and applied to properly allocate the renewable and non-renewable exergy costs and CO2 emission cost among the different products of multiproduct plants. Since Brazilian electricity is consumed in the upstream processing stages of the fuels used in the generation thereof, an iterative calculation is used. The electricity mix comprises thermal (coal, natural gas and oil-fired), nuclear, wind and hydroelectric power plants, as well as bagasse-fired mills, which, besides exporting surplus electricity, also produce sugar and bioethanol. Oil and natural gas-derived fuels production and biodiesel fatty acid methyl-esters (FAME) derived from palm oil are also analyzed. It was found that in spite of the highest total unit exergy costs correspond to the production of biofuels and electricity, the ratio between the renewable to non-renewable invested exergy (cR/cNR) for those fuels is 2.69 for biodiesel, 4.39 for electricity, and 15.96 for ethanol, whereas for fossil fuels is almost negligible. - Highlights: • Total and non-renewable exergy costs of Brazilian transportation fuels are evaluated. • Specific CO2 emissions in the production of Brazilian transportation fuels are determined. • Representative production routes for fossil fuels, biofuels and electricity are reviewed. • Exergoeconomy is used to distribute costs and emissions in multiproduct processes

    In this paper, vector error correction model (VECM) has been utilized to model the dynamic relationships between world crude oil price and the sector indices of Malaysia. The sector indices have been collected are covering the period Jan 1998 to Dec 2013. Surprisingly, our investigations show that oil price changes do not Granger-cause any of the sectors in all of Malaysia. However, sector indices of Food Producer and Utilities are found to be the cause of the changes in world crude oil prices. Furthermore, from the results of variance decomposition, very high percentage of shocks is explained by world crude oil price itself over the 12 months and small impact from other sector indices.

    The leaves of jaborandi are commercially exploited in the Brazilian Northeast for industrial extraction of pilocarpine, an alkaloid with potent cholinergic activity. The leaves also contain an essential oil whose composition is registered in the literature in a confusing and incomplete way. Chemical re-examination of the essential oil from five distinct Pilocarpus species was conducted together with an analysis of the leaves used by local industry. It was found to contain terpenes, sesquiterpenes and ketones. Some of them are reported for the first time in the genus.

    Previous studies showed that conventional coherent backscatter radar measurements of the Doppler velocity of the so-called 150 km echoes can provide an alternative way of estimating ionospheric vertical plasma drifts during daytime hours (Kudeki and Fawcett, 1993; Chau and Woodman, 2004). Using observations made by a small, low-power 30 MHz coherent backscatter radar located in the equatorial site of São Luís (2.59° S, 44.21° W; -2.35° dip lat), we were able to detect and monitor the occurrence of 150 km echoes in the Brazilian sector. Using these measurements we estimated the local time variation of daytime vertical ionospheric drifts in the eastern American sector. Here, we present a few interesting cases of 150 km-echoes observations made by the São Luís radar and estimates of the diurnal variation of vertical drifts. These cases exemplify the variability of the vertical drifts in the Brazilian sector. Using same-day 150 km-echoes measurements made at the Jicamarca Radio Observatory in Peru, we also demonstrate the variability of the equatorial vertical drifts across the American sector. In addition to first estimates of the absolute vertical plasma drifts in the eastern American (Brazilian) sector, we also present observations of abnormal drifts detected by the São Luís radar associated with the 2009 major sudden stratospheric warming event.

    Full Text Available This essay aims seeks to broaden the debate on the incorporation of the theme Entrepreneurship in the Public Sector (EPS through the literature review on the reflective character to be taken to transpose concepts from the private sector to the public sector. It was understood that needs a critical discussion on the process of appropriating that theme in Brazil. It was observed that the Brazilian Public Administration is marked by a hybrid model of administration, in which patrimonial practices, bureaucratic and managerial coexist, making the complex adaptation of entrepreneurship. Therefore, we must be wary of exaggerated expectations regarding this theme in Brazilian Public Administration, as have several limitations that meet the sustainability of democratic governments.

    1999-07-01

    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. [Spanish] Desde principios de los anos noventa Brasil ha iniciado un programa de reformas en su sector electrico que incluye la privatizacion del servicio electrico y la desverticalizacion. Los objetivos principales eran promover una industria de la energia orientada comercialmente de la energia electrica, atractiva a las inversiones privadas.

    This study developed a method to evaluate the evolution of energy intensity in the Brazilian industrial sector from 1995 to 2004. In order to do so, it was necessary to obtain six different measures (indicators) of the sector energy intensity. Considering the concept of energy intensity as the ratio between energy consumption and the level of economic activity, two measures were used for the energy consumption: a thermal (physical) and an economic one. For the level of economic activity, three measures were used: value of production, value of delivered goods and added value. In the Brazilian industrial sector, most of these indicators have behaved in a similar way. In a disaggregated way, energy intensity indicators show a unified direction of its evolution. However, a more elaborate study on the consumption profile of the Brazilian industrial sector and its economical activities indicates the presence of important deviations concerning the annual rate of change in energy intensity. Besides, there is no evident relation between these deviations and the composition of the different indicators of energy intensity. (author)

  13. Natural-gas-powered thermoelectricity as a reliability factor in the Brazilian electric sector

    International Nuclear Information System (INIS)

    The introduction of natural-gas-powered thermoelectricity into the Brazilian generation sector can be considered as a very complex energy, economic, regulatory and institutional revision. Brazil is a country with very specific characteristics in electricity generation, as approximately 80% of the generating capacity is based on hydroelectricity, showing strong dependency on rain and management of water reservoirs. A low rate of investment in the Brazilian Electricity Industry in the period of 1995-2000, associated with periods of low rainfall, led to a dramatic lowering of the water stocks in the reservoirs. With this scenario and the growing supply of natural gas, both from within Brazil and imported, natural gas thermal electric plants became a good option to diversify the electrical supply system. In spite of the Brazilian Government's efforts to install such plants, the country was faced with severe electricity rationing in 2001. The objective of this work is to show the need to continue with the implementation of natural gas thermal electricity projects, in a manner that allows flexibility and guarantees greater working reliability for the entire Brazilian electricity sector. Taking into account the world trend towards renewable energy, the perspectives of usage of biofuels in the Brazilian Energy Matrix and in electrical energy generation are also analyzed. The very issue of electrical power efficiency in Brazil and its challenges and strategic proposals from the standpoint of Government Programs and results provided so far are presented. The technological constraints in order to put on stream the thermal electric plants are also analyzed. The article concludes with a positive perspective of the usage of natural gas as to be the third pillar in the Brazilian Energy Matrix for the years to come

    Full Text Available The major purpose of this paper is to examine the influence of Foreign Direct Investment’s (FDI entrance in the several Brazilian economies’ sectors. In order to this, are observed the global flow of FDI, the Brazilian legislation that regulates the FDI’s entrance, such as the historical context that has influenced the FDI’s inflows in Brazil. Then it is analyzed the entrance of FDI and the growth of Brazilian’s Economy sectors, between year 2000 and 2008, observing if there is a direct relations between them. Finally, contends that the two analyzed factors are connected, but the national economy’s growth influences more in the entrance of FDI then the opposite, and also are shown others factors that influences the FDI entrance and the intern growth, suggesting more national investments in order to attract more FDI to enlarge the international commerce and obtain more technology development.

  17. Evaluating the effect of exchange rate and labor productivity on import penetration of Brazilian manufacturing sectors

    Directory of Open Access Journals (Sweden)

    João Paulo Martin Faleiros

    2016-01-01

    Full Text Available In recent years, several economists have argued that the sharp loss of competitiveness of the Brazilian industry was caused by a strong exchange rate appreciation. However, other economists have attributed this loss of competitiveness to the dismal growth of labor productivity in the Brazilian industrial sector. The present paper proposes to estimate the differential impacts of variations in exchange rate and labor productivity on the Brazilian market share of imports measured by the coefficient of import penetration of total demand for manufacturing goods. We start by developing a simple theoretical model to investigate under what conditions the impacts of an exchange rate depreciation and an increase in labor productivity would differ. We test the theoretical implications of the model by means of a GMM panel data analysis focusing on 17 manufacturing sectors in the period between 1996 and 2011. Our results suggest that both variables matter to explain the coefficient of import penetration. Nevertheless, labor productivity has the strongest negative impact on the market share of imported goods, even after controlling for sector fixed-effects.

    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. PMID:27533363

    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.

    The aim of this paper is to analyse the use of Capital Asset Pricing Model (CAPM) Beta in the Brazilian electric distribution sector tariffs review. The betas applied by the Regulatory Agency are defined using data from the American, English and Brazilian markets. These betas will then be compared to the betas obtained in the domestic market. The betas were directly obtained from an economic-financial databank largely employed by the market. The sample is composed of companies' shares, priced at Sao Paulo Stock Market. Their main activity is the distribution of electric energy between July 2002 and July 2007. The results of mean betas obtained for the distribution segment, with values close to the ones applied by the regulatory agency for the cycle of tariff reviews between 2007-2010. (author)

  5. Japan's oil market and refining sector

    International Nuclear Information System (INIS)

    The present economic situation in Japan is discussed. In particular, the focus is on fluctuations in oil product demand, imports of crude oil, and the refining industry. Throughout the 1990s, Japan was plagued by a volatile economy and the new millennium has shown no improvement. A prolonged recession means that the country now has little confidence in its leaders and its institutions, consumer confidence is low and asset values have deflated. Due to a low birth rate and long life expectancy, the population is aging and this means lower savings rates. The contrast between the present situation and the so-called economic miracle once enjoyed by the Japanese is hard to accept, but despite all this, the Japanese lifestyle and economy are to be envied

    International Nuclear Information System (INIS)

    The British Columbia (BC) oil and gas service sector is collaborating with the BC Ministry of Energy and Mines (MEM) to enhance the competitiveness of oil and gas service providers in Northeast BC. The MEM agreed to provide one-time funding to develop this marketing strategy for the oil and gas sector, particularly for small to medium-sized companies with limited resources. This document is also a resource tool for suppliers in the sector that have developed and are implementing their own marketing plans and wish to enhance elements of their own plans. The strategy also outlines the potential role of associations in Northeast BC that represent the service sector. It links their marketing activities with the activities of individual service providers. Local service providers (LSP) include companies in a wide range of businesses such as drilling support, transportation, health and safety services, and construction. Six issues that directly impact the competitiveness of LSPs were also presented along with recommendations for participants in the service sector, associations and individual companies. tabs., figs., 11 appendices

    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.

    Kuwait is stepping up its efforts to position itself as one of the main transport and logistics hubs in the Gulf. Looking at the logistics performance index Kuwait is placed behind UAE and Bahrain but (far) ahead of Saudi Arabia, Qatar, Oman, Iraq and Iran. Besides, Kuwait is gaining ground, investing heavily in new infrastructure which is intended not only to meet the country's own needs but also the needs of the wider region.Kuwait has nearly 500 kilometres of coastline along the Persian (Arabian) Gulf and is strategically positioned at the mouth of the waterways to Iraq and Iran. This could give Kuwait the advantage to serve as one of the most important regional hubs for shipping and transportation in the Gulf region. This becomes especially true when a planned railway line connecting Kuwait with Saudi Arabia, Iraq, Iran and especially Turkey becomes in service. Information is presented on: government plans, existing port infrastructure in Kuwait, developments and opportunities in the existing ports, the oil ports and terminals, investment and business opportunities.

  17. Environmental valuation for long-term strategic planning. The case of the Brazilian power sector

    International Nuclear Information System (INIS)

    If not properly dealt with over compatible horizons, environmental issues may cause ventures to incur higher costs and extend over longer implementation periods. Prompted by the uncertainties and risks inherent in these issues, as well as by the need for long-term plans to incorporate sustainable development principles, the Brazilian Power Sector is encouraging the inclusion of environmental aspects as a decision variable right from the start of the planning cycle. The purpose of this paper is to bolster efforts to include in this sector's expansion plans, costs resulting from environmental degradation of the environment. The paper offers an overview of the methodology developed to assess and include in long-term planning for this sector, external environmental costs linked to hydro-power and thermo-power generation. It suggests the use of environmental economic valuation techniques a practice commonly used to analyze the degradation of natural capital in various countries as well as assessing projects and programs, adopting the premises and simplifications required for application over the longer term.21 refs

    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.

  19. Evaluating public policy mechanisms for climate change mitigation in Brazilian buildings sector

    International Nuclear Information System (INIS)

    This paper applies a multi-criteria analysis (MCA) and marginal abatement cost curves (MACC) to evaluate public policies mechanisms to promote the dissemination of energy efficiency (EE) and on-site renewable energy sources (RES) technologies in Brazilian buildings sector. The objective here is to bring together the advantages of both methods in order to provide more valuable insights to policy makers. The MCA results show that in the case of more integrative policies, which considers, for instance, potential of jobs creation, the mechanisms to foster distributed RES and solar water heaters are better ranked than in MACC analysis, where only cost-effectiveness of each option is evaluated. Other key finding is that: (1) there is a significant cost effective potential that could be reached through alternative mechanisms not implemented yet in the country, such as public procurement regulation and building codes and; (2) minimum energy performance standards (MEPS) could be broader in scope and more stringent and include the use of energy in standby mode and tubular fluorescent lamps. In particular, some important appliances such as large air conditioning devices should have more aggressive MEPS. - Highlights: • We apply a multi-criteria analysis to evaluate EE and RES policies mechanisms. • We apply marginal abatement cost curves to evaluate EE and RES policies mechanisms. • We provide rankings of mechanisms according to their prospective potential impacts. • There is a significant cost effective energy saving potential in Brazilian buildings. • Brazil should improve MEPS and implement other policy mechanisms

    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.

    Equatorial ionospheric plasma bubble irregularity development and dynamics during the major magnetospheric storm of 26 August 1998 are investigated using the data collected by a multistation and multi-instrument diagnostic network operated at equatorial and low latitude sites in Brazil, and auroral electrojet activity (AU/AL), IMF, and Dst indices. A magnetospheric disturbance onset in the morning of 26 August 1998 was initiated by a solar wind shock and associated IMF Bz polarity reversals and ssc that were soon followed by a succession of substorm-like auroral electrojet (AE) intensifications and Dst development. An IMF Bz southward turning and associated AE intensifications in the Brazilian dusk sector produced intense prompt penetration eastward electric field that caused large F region vertical drift and consequently the developments of intense postsunset equatorial anomaly and a series of intense plasma bubbles, the latter event lasting the entire night, as observed by digital ionosondes at São Luís (2.33°S, 315.8°E, dip angle: -.5°) and Fortaleza (3.9°S, 321.55°W, dip angle: -9°) and an all-sky imager, two scanning photometers, and a Digisonde at the low-latitude site Cachoeira Paulista (22.6°S, 315°E dip angle: -28°). A notable aspect of the dynamics of the bubbles was their initially very low eastward drift velocity which turned into steadily increasing westward velocity that lasted till early morning hours. The results show for the first time a relationship between the zonal drift velocities of optically observed large-scale bubbles (tens to hundreds of kilometers) and that of the smaller scale (kilometer sizes) structures as observed by a digital ionosonde. The results point to the dominant role of a disturbance dynamo associated westward thermospheric wind to maintain the plasma irregularity drift increasingly westward going into postmidnight hours. As an important finding, the results further show that significant contribution to the

  4. The energy efficiency of crude oil refining in Brazil: A Brazilian refinery plant case

    International Nuclear Information System (INIS)

    This article evaluates energy efficiency in Brazilian crude oil refining in comparison with the crude oil refining in the United States between 1930 and 2008. It aims to show that increased refinery complexity reduces the energy consumption of products of high value added. Moreover, the article shows that improvements in energy efficiency result in higher quality products and increased processing of oil. A Brazilian refinery with a capacity of 157,000 barrels per day (kbpd) was modernized in 2008 at a cost of US $1.3 billion. As a result, its capacity increased by 17%, from 157 to 189 kbpd. Its complexity index also rose from 3.2 to 6.8, allowing an improvement in the EII (energy intensity index) from 110% to 93%. In relation to the crude oil processed before being modernized, energy consumption fell from 0.75 to 0.52 MBtu (million British thermal units) per barrel processed. These proceedings show that increases in complexity reduce the energy consumed in the production of final products with high value added, such as gasoline, diesel and jet fuel. -- Highlights: → Increased refinery complexity reduces the energy consumption of products of high value added. → Improvements in refinery energy efficiency result in higher quality products and increased processing of oil. → Brazilian refineries were not affected significantly in the 2008 crisis, such as the US refineries, due to many factors. → The EII of Brazilian refining presents real opportunities for gains through changes in the profile of energy consumed.

    The present study presents an analysis of the options available for the mitigation of CO{sub 2} emissions in the Brazilian power sector. The objective is to verify the potential use of wastes for electrical energy generation and its competitiveness in comparison with other sources of renewable energy. A comparison was made using marginal abatement cost curves derived from a reference scenario obtained from earlier studies dealing with the expansion of the Brazilian power sector. The results showed that the availability of wastes is significant and that they can be used at a cost 20-60% lower than that of wind power generation, a subsidized source of energy in Brazil. It can therefore be concluded that it would be more efficient if incentives were applied to the use of wastes for electrical power generation since it offers socio-environmental benefits which go far beyond the reduction of CO{sub 2} emissions.

    Full Text Available Brazil is a developing country in the midst of major social, economic, technological, cultural, and educational change. In the areas of technology and education, the transfer of information and knowledge, with the support of hypermedia applications, Internet, and distance learning have been a major concern of public and private entities, especially in regards to agriculture and animal production. In a country with approximately 195 million inhabitants and 8.5 million square kilometers, where the rural sector accounts for 25% of gross domestic product, 30.3% of exports, and 37% of jobs1, the use of information and communication technologies in education and inclusion is fundamental to promoting developmental strategies and citizenship. In this study, we sought to describe the process of modeling, development and dissemination of hypermedia applications for the Brazilian rural sector, taking as a case unit, the “Digital Citizen” Internet portal. A qualitative research, with exploratory-descriptive goals, and a case study based on documentary and observation is presented. In the current research and beyond, the practices related to modeling, development, and dissemination of hypermedia applications via distance learning (Moodle® and Flash®, as well as investigations and discussions involving government processes and practices related to digital inclusion and social development of rural citizen Brazil are specified. We conclude that Brazil is tackling the challenge of digital and social inclusion, based on a project whose main components included (a deploying an infrastructure for telephone and broadband across the rural areas, (b offering free internet in public schools and rural communities, (c promoting projects and companies that work with hypermedia applications, and (d supporting initiatives that involve the development and provision of services at a distance.

  9. How to use the clean development mechanism in the residential sector? The case of Brazilian refrigerators

    International Nuclear Information System (INIS)

    The definition of simple and reliable emission baselines is crucial to foster clean development mechanism (CDM) projects. This paper assesses a project methodology that could boost large-scale energy-efficiency projects in the sector of domestic appliances. The baseline appliance is defined a priori in a 'conservative' manner as the design option minimizing life-cycle social costs. The project methodology consists in a program which rebates new appliances according to their emission savings compared to the baseline. Is the proposed baseline acceptable? What could be the impact of such project on emissions? To address these questions, we look for insights from a hypothetical case on Brazilian refrigerators. A rational choice model is developed which assumes that households select design options minimizing life-cycle private costs. Results suggest that electricity tariff distortions and financial constraints might hamper project performances and allow significant free-riding. Low income households remain trapped into low-efficiency choices and high income households adopt outperforming appliances, whether rebated or not. However, simple solutions likely to improve the project methodology do exist

  10. Oil demand reduction in an oil crisis. Evaluation of oil demand-reducing measures for the transportation sector

    International Nuclear Information System (INIS)

    Every IEA member state must have in place measures to reduce oil demand during oil supply emergencies. The transport sector offers significant opportunities to reduce oil demand with relatively limited impact on the overall economy. To determine which measures are useful in the Dutch situation, this report performs a quick scan of a number of demand restraint measures in the transport sector. The quick scan ranks measures by their effectiveness, feasibility, and efficiency. Based on the quick scan results, three measures have been selected for further research (Sunday driving ban, work-trip reduction, and carpooling). Additionally, the effects of price increases on oil demand have been examined. Five refineries and a large petrochemical industry sector are based in the Netherlands. Therefore, the shares of passenger road transport (20%) and freight road transport (12%) in the national oil demand are comparatively low. As a consequence an oil demand reduction in road transport of at least 20% to 30% is required to meet the national oil demand reduction target of 7% to 10% agreed within IEA. Price effects during an oil crisis are uncertain given limited research, and estimated to reduce oil demand from passenger road transport by 15% to 35% and oil demand from freight road transport by 10% to 25%. Given the uncertainty, this effect was halved to obtain a conservative estimate of 2% to 4% of national oil demand reduction as a result of price effects. A Sunday driving ban can lead to reductions of 50% to 80% of passenger travel on Sundays, leading to savings of 1% to 1.5% of national oil demand. Work-trip reduction policies can reduce worktrips by 10% and lead to reductions of 0.5% to 1% of total oil demand. Carpooling has the greatest potential, reducing work trips up to 30% and leading to 0% to 2.5% savings of national oil demand. The broad range of the latter estimate is due to the limited options available to influence motorists to share their vehicles with others

    Full Text Available The 28 October 2003 solar flare (X-ray Class X17.2 was one of the most intense solar flares observed in the recent past. In the present investigation we show the unusual ionospheric effects observed in the Brazilian sector during this solar flare, using both the ionospheric sounding observations obtained at the UNIVAP stations: Palmas (7–10.2° S, 48.2° W, dip lat. 5.5° S and Sao Jose dos Campos (23.2° S, 45.9° W, dip lat. 17.6° S, Brazil; and ground-based global positioning system (GPS data obtained at the "Instituto Brasileiro de Geografia e Estatística" (IBGE stations: Imperatriz (5.5° S, 47.5° W, dip lat. 2.9° S, Brasilia (15.9° S, 47.9° W, dip lat. 11.7° S, Presidente Prudente (22.3° S, 51.4° W, dip lat. 14.9° S, and Porto Alegre (30.1° S, 51.1° W, dip lat. 20.7° S, Brazil; on two consecutive days, viz., 27 (without solar flare and 28 (with solar flare October 2003. It should be mentioned that the vertical total electron content (VTEC from the GPS observations obtained during the solar flare showed an unusual simultaneous increase in the VTEC values at about 11:00 UT at all four stations associated with the solar flare EUV enhancements and lasted for about 3 h. However, no ionograms were obtained at any of the two UNIVAP stations for a period of about 1 h between about 11:00 to 12:00 UT. Before 11:00 UT (from about 10:45 UT and after 12:00 UT (to about 16:00 UT, the ionograms were only partial, with the low frequency end missing. During this intense solar flare, hard X-rays (1 to 10 A, as observed by the GOES 12 satellite, were ejected by the Sun during a long period (several hours, with peak radiation at about 11:10 UT. These hard X-ray radiations can penetrate further into the ionosphere, causing an increase in ionization in the lower part of ionosphere (D-region. In this way, the lack of ionograms or partial ionograms, which indicates no echoes or partial echoes of the transmitted digital ionosonde signals, are

  15. The use of ethanol from sugar cane in the Brazilian transport sector

    International Nuclear Information System (INIS)

    The use of Ethanol as a fuel is a significant contribution to the efforts for reducing greenhouse effect related to gas emissions. The main objective of the present work, is to assess Brazil's performance regarding activities aimed at reducing harmful gas emissions, in the global context of the intensification of the greenhouse effect, assumed as a working hypothesis. Brazil's estimated emissions of greenhouse effect related to gases are far less than those of developed countries. The per capita consumption of energy and of fossil fuels is still quite low in Brazil. However, the means for reducing harmful gas emissions and the initiatives to control the greenhouse effect should not be directed to the maintenance of the present low level of energy consumption, for this would have negative repercussion on the economic development of the country. Developed countries have focused on the more rational uses of energy, i.e. more efficient and less polluting fuels, so as to reduce their own levels of greenhouse effect related to gas emissions. In this connection, the use of ethanol in Brazil for the transportation sector may prove to be an important alternative furthering the efforts to stabilised the actual level of gases in the atmosphere. The energy derived from biomass, and in this case, from a renewable, clean source, i.e., from sugar cane, has the unquestionable advantage of permitting the almost complete reabsorption of Carbon Dioxide emitted through the combustion of fuel alcohol. This closed cycle allows, in principle, to increase the energy supply, essential for sustained economic growth, without hazards to the environment. Furthermore, the Brazilian Fuel Alcohol Program has the potential to attract international interest as an important alternative relative to the efforts for controlling the global dangers of the greenhouse effect, as will be discussed in greater detail further on in this paper.

    The seed oils of different varieties of 4 Passiflora species cultivated in Brazil were analyzed and compared regarding their physicochemical parameters, fatty acid composition and the presence of minor components, such as phytosterols, tocopherols, total carotenoids, and phenolic compounds. The antioxidant capacities of the oil extracts were determined using the 2,2'azinobis [3-ethylbenzothiazoline-6-sulfonic acid] and oxygen radical absorbance capacity methods. The results revealed that all studied Passiflora seed oils possessed similar physicochemical characteristics, except for color, and predominantly contained polyunsaturated fatty acids with a high percentage of linolenic acid (68.75% to 71.54%). Other than the total phytosterol content, the extracted oil from Passiflora setacea BRS Pérola do Cerrado seeds had higher quantities (% times higher than the average of all samples), of carotenoids (44%), phenolic compounds (282%) and vitamin E (215%, 56%, 398%, and 100% for the α-tocopherol, β-tocopherol, γ-tocopherol, and δ-tocopherol isomers, respectively). The methanolic extracts from Passiflora setacea BRS Pérola do Cerrado seed oil also showed higher antioxidant activity, which was positively correlated with the total phenolic, δ-tocopherol, and vitamin E contents. For the first time, these results indicate that Passiflora species have strong potential regarding the use of their seeds for oil extraction. Due to their interesting composition, the seed oils may be used as a raw material in manufacturing industries in addition to other widely used vegetable oils. PMID:26512548

    This paper introduces an improved total-factor ESTR (energy-saving target ratio) index, which combines the sequence technique and the “energy direction” to a DEA (data envelopment analysis) model, in order to measure the possible energy saving potential of a manufacturing sector. Afterward, the energy saving potentials of four different energy carriers, namely coal, gasoline, diesel oil and electricity, for 27 manufacturing sectors during the period of 1998–2011 in China are calculated. The results and its policy implications are as follows: (1) the average ESTRs of coal, gasoline, diesel oil and electricity are 1.714%, 49.939%, 24.465% and 3.487% respectively. Hence, energy saving of manufacturing sectors should put more emphasis on gasoline and diesel oil. (2) The key sectors for gasoline saving is the energy-intensive sectors, while the key sectors for diesel oil saving is the equipment manufacturing sectors. (3) The manufacture of raw chemical materials and chemical products sector not only consumes a large amount of oil, but also has a low efficiency of oil usage. Therefore, it is the key sector for oil saving. (4) Manufacture of tobacco and manufacture of communication equipment, computers and other electronic equipment are the benchmark for the four major energy carriers of energy-saving ratios. - Highlights: • An improved total-factor energy-saving target ratio is proposed. • Energy saving potentials of energy carriers for sectors in 1998–2011 are calculated. • Policy implications for energy savings in sectors and energy carriers are discussed. • Some suggestions for the energy policies of China's economy are discussed

    International Nuclear Information System (INIS)

    The effects of a world oil price shock on U.S. agriculture are analyzed in an economywide environment. The authors use an input-output model to analyze the direct and indirect cost linkages between energy and other sectors of the economy. Then, to allow sectoral output adjustment and the effects on the U.S. current account, they use the U.S. Department of Agriculture/Economic Research Service Computable General Equilibrium (CGE) model to analyze the sectoral effects under three different macro adjustment scenarios. The effects on agriculture are not limited to the direct and indirect energy costs. Exchange rate or foreign borrowing adjustments to higher oil import costs and government support programs for agriculture also matter

    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.

    Andirobeira is an Amazonian tree, the seeds of which produce a commercially valuable oil that is used in folk medicine and in the cosmetic industry. Andiroba oil contains components with anti-inflammatory, cicatrizing and insect-repellant actions. However, virtually nothing is known of the safety of this oil for humans. The aim of this work was therefore to investigate the hematotoxicity, genotoxicity and mutagenicity of andiroba oil using the comet and micronucleus assays, and to assess its antioxidant properties and lipidome as a means of addressing safety issues. For the experiments, andiroba oil was administered by gavage for 14 consecutive days in nulliparous female Swiss mice randomly distributed in four groups: negative control and three doses of oil (500, 1000 and 2000 mg/kg/day). These doses were chosen based on recommendations of the OECD guideline no. 474 (1997). GC/MS was used to investigate the free fatty acid, cholesterol and triterpene content of andiroba oil in a lipidomic analysis. No clinical or behavioral alterations were observed throughout the period of treatment, and exposure to andiroba oil at the doses and conditions used here did not result in hematotoxic, genotoxic or mutagenic effects. Tests in vitro showed that oil sample 3 from southwestern of Brazilian Amazon had a high antioxidant capacity that may protect biological systems from oxidative stress, although this activity remains to be demonstrated in vivo.

  10. Oil bioremediation processes in Brazilian marine environments : laboratory simulations

    International Nuclear Information System (INIS)

    Bioremediation methods have been used in Brazil to remediate contaminated soils from refinery residues. In particular, bioremediation is a process that can reduce the amount of oil that reaches shorelines, by enhancing natural biodegradation. This presentation presents the results of a laboratory study in which seawater contaminated with light crude oil was bioremediated in a period of 28 days using NPK fertilizer. Whole oil gas chromatography and gas chromatography-mass spectrometry analyses of the hydrocarbon fractions were used to determine the extent of oil biodegradation. It was determined that natural degradation occurred in the first 4 days, and mostly through the evaporation of light end n-alkanes. Biodegradation of n-alkanes was found to be most effective after 7 days, and no changes were observed in the relative abundance of steranes and triterpanes. It appears that the addition of NPK nutrient reduces the biodegradation potential of polyaromatic compounds. Seawater samples were also measured to determine the efficiency of bioremediation. The use of NPK fertilizer resulted in higher toxicity after 14 days probably due to the creation of metabolites as polyaromatic compounds biodegrade. Non toxic levels were found to be reestablished after 28 days of bioremediation. 16 refs., 4 tabs., 6 figs

    The equatorial electrojet (EEJ) is a narrow band of current flowing eastward at the ionospheric E-region altitudes along the dayside dip equator. Mutually perpendicular electric and magnetic fields over the equator results in the formation of Equatorial Ionization Anomaly (EIA) which in turn generates large electron density variabilities. Simultaneous study on the characteristics of EEJ and EIA is necessary to understand the role of EEJ on the EIA variabilities. Present study reports simultaneous variations of EEJ and GPS-TEC over Indian and Brazilian sectors to understand the role of EEJ on the day-to-day characteristics of the EIA. Magnetometer measurements during the low solar activity year 2004 are used to derive the EEJ values over the two different sectors. The characteristics of EIA are studied using two different chains of GPS receivers along the common meridian of 770E (India) and 450W (Brazil). The diurnal, seasonal and day-to-day variations of EEJ and TEC are described simultaneously. Variations of EIA during different seasons are presented along with the variations of the EEJ in the two hemispheres. The role of EEJ variations on the characteristic features of the EIA such as the strength and temporal extent of the EIA crest etc., have also been reported. Further, the time delay between the occurrences of the day maximum EEJ and the well-developed EIA are studied and corresponding results are presented in this paper. Further, the results from a study on the noon time bite-outs at the anomaly crest locations with their absence over the equator in the Indian and Brazilian sector are also discussed in this paper.

  12. Symmetric and asymmetric US sector return volatilities in presence of oil, financial and economic risks

    International Nuclear Information System (INIS)

    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.

    Odonate larvae can be serious pests that attack fish larvae, postlarvae, and fingerlings in fish culture tanks, causing significant loss in the supply and production of juveniles. This study reports a screen of the essential oils (EOs) of Nectandra megapotamica (Sprengel) Mez, Nectandra grandiflora Nees, Hesperozygis ringens (Bentham) Epling, Ocimum gratissimum L., Aloysia gratissima (Gillies & Hooker) Troncoso, and Lippia sidoides Chamisso against Coenagrionidae larvae. In addition, the most effective EO and its 50% lethal concentration (LC50) and chemical analysis are described. The larvae of Acanthagrion Selys, Homeoura Kennedy, Ischnura Charpentier, and Oxyagrion Selys were used to assess the EO effects. EO obtained from H. ringens, O. gratissimum, and L. sidoides showed the highest larvicidal effects at 19 h of treatment. The major constituents of the EO of H. ringens include pulegone and limonene, while eugenol and Z-beta-ocimene predominate in the EO of O. gratissimum, and carvacrol and rho-cymene were the major compounds of the EO of L. sidoides. Leaf EOs from H. ringens, O. gratissimum, and L. sidoides showed activity against Coenagrionidae larvae at similar concentrations with LC50s of 62.92, 75.05, and 51.65 microl liter(-1), respectively, and these were considered the most promising treatments.

  17. Can Venezuela's oil sector endure Chavez' ambitions any longer?

    International Nuclear Information System (INIS)

    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.

  19. Oil and gas equipment and services country sector profile in Pakistan

    International Nuclear Information System (INIS)

    This report presents a market overview of the oil and gas sector in Pakistan where government efforts to privatize state-owned companies will help make the sector more efficient. The potential for Canadian suppliers to enter into joint ventures to establish local production facilities and transfer technology expertise was also described along with the key factors shaping market growth, sector reform and opportunities for actual and planned projects. Pakistan is a modest producer of oil and gas. It imports 80 per cent of its crude oil requirements but is self-sufficient in natural gas. This may change as demand increases. The key player in the Pakistani petroleum industry is the state-owned Oil and Gas Development Corporation Ltd. (OGDCL). Most domestic natural gas is produced by Pakistan Petroleum Ltd. Proposed pipelines from oil and gas deposits in Turkmenistan and Kazakhstan could provide Pakistan with revenue through transport fees. Pakistan is offering a full range of options to investors through an ambitious privatization program. This report described the competitive environment with reference to local capabilities, international competition, Canadian position, and a competitive advantage through Canadian government policies and initiatives. A section of the report on public-sector customers described the organizations that manage and approve oil and gas projects. Considerations for market-entry in Pakistan were also outlined

  20. Oil's role in free trade agreement crux of Mexico's petroleum sector dilemma

    International Nuclear Information System (INIS)

    Mexico's president Salinas' efforts at privatization have not yet touched Mexico's most valuable industry, oil. That remains under control of state owned Petroleos Mexicanos. Pemex and Mexico's huge oil union have come under increasing criticism for alleged abuses of power. In addition, controversy rages as to the true extent of Mexican oil resources and whether Pemex has the wherewithal to meet domestic demand and sustain oil exports. Critics also contend opening Mexico's oil sector to foreign participation would introduce new efficiencies and cost cutting measures in the cash strapped state oil industry. This paper reports that at the center of the controversy is the proposed Free Trade Agreement among Mexico, the U.S., and Canada, pushed strongly by Salinas. Oil's role in the FTA may prove the pact's main sticking point

    The central issue of debate is the need to align the energy sector's options and organization with changing global patterns of economic and social development, characterized by the increasing role played by the private sector, greater integration in the world economy, and new economic and social priorities such as efficiency, decentralization, deregulation, and a closer attention to environmental issues. In this context, the aim of the work is to introduce the incentive to the competition as government policy instrument for Brazilian electric power sector.

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

    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.

    2016-08-01

    The present paper reports on the development of a novel extraction induced by emulsion breaking (EIEB) method for the determination of chloride in crude oils. The proposed method was based on the formation and breaking of oil-in-water emulsions with the samples and the consequential transference of the highly water-soluble chloride to the aqueous phase during emulsion breaking, which was achieved by centrifugation. The determination of chloride in the extracts was performed by ion chromatography (IC) with conductivity detection. Several parameters (oil phase:aqueous phase ratio, crude oil:mineral oil ratio, shaking time and type and concentration of surfactant) that could affect the performance of the method were evaluated. Total extraction of chloride from samples could be achieved when 1.0g of oil phase (0.5g of sample+0.5g of mineral oil) was emulsified in 5mL of a 2.5% (m/v) solution of Triton X-114. The obtained emulsion was shaken for 60min and broken by centrifugation for 5min at 5000rpm. The separated aqueous phase was collected, filtered and diluted before analysis by IC. Under these conditions, the limit of detection was 0.5μgg(-1) NaCl and the limit of quantification was 1.6μgg(-1) NaCl. We applied the method to the determination of chloride in six Brazilian crude oils and the results did not differ statistically from those obtained by the ASTM D6470 method when the paired Student-t-test, at 95% confidence level, was applied.

    This paper presents a study of Pc4-5 geomagnetic pulsations illustrated by those which were observed after the sudden commencement of May 02 of 2010 at 09 : 08 UT at the Brazilian stations TTB, VSS and SMS. We carry out the spectral analysis of a bivariate data using the Morse wavelets and calculate polarization attributes (ellipticity ratio, tilt angle and phase difference) in the time-frequency domain. The main pulsation wave packets occurred, for the selected day, around noon and a small enhancement of the pulsation amplitude is observed in the TTB station. A change in the pulsation polarization has been found for the TTB station, which we have attributed to effects of the equatorial electrojet.

  7. Applying a Virtual Economy Model in Mexico's Oil Sector

    International Nuclear Information System (INIS)

    The state of Mexico's oil industry, including the accomplishments of Pemex, Mexico's national oil company, was discussed, with particular reference to the progress made in the period of 1988-1994, and the outlook for innovations in the post-Salinas era. The concept of an evolutionary trend from a command economy (State as sole producer), towards market (State as regulator) or mixed economies (State as business partner) in developing countries, was introduced, placing Pemex within this evolutionary model as moving away from centralized control of oil production and distribution, while achieving international competitiveness. The concept of ''virtual market economy'' was also discussed. This model contains the legal basis of a command economy, while instituting modernization programs in order to stimulate market-economic conditions. This type of economy was considered particularly useful in this instance, sine it would allow Pemex units to operate within international performance and price benchmarks while maintaining state monopoly. Specific details of how Pemex could transform itself to a virtual market economy were outlined. It was recommended that Pemex experiment with the virtual mixed economy model; in essence, making the state a co-producer, co-transporter, and co-distributor of hydrocarbons. The effects of such a move would be to bring non-debt funding to oil and gas production, transmission, and associated industrial activities

    Full Text Available China, the most populated state on the planet, has experienced a spectacular economic growth after 1978, with a mean annual growth rate of G DP of about 10%. Thus, China has become the second largest world economic power. Econ omic development has entailed significant social-economic changes, increasing lif e expectancy and urbanization degree. At the same time, the power demand (oil included has grown considerably and not before long, China has become the largest energy consumer and the seco nd oil consumer in the world. But, being unable to ensure its increasing demands from intern al sources, starting with 1993, China has become a net importer of oil. A good indicator for oil consumption increase is the big number of vehicles that drive along the China’s roads. As the driving force of the economy, the meeting of energy demands is one of the main priorities of eve ry state, but the access to resources may become increasingly difficult if they start to dwin dle, while the technological progress lags behind.

    2008-07-01

    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)

    2015-12-01

    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.

  13. Planning Oil Prices In The World Market And Preventive Policies In Energy Sector Of Iran

    International Nuclear Information System (INIS)

    The planning of oil prices in the world can not be analyzed by means of the market-competition theory or the game theory. The current prices seem to be influenced greatly by large energy consuming industries of developed countries, oil producing corporations and cartels, and oil productions outside of OPEC. There is a lack of necessary long term policies and planning so that drastic changes in market prices can be avoided. The goal of this paper is to suggest new policies by means of discussing in following issues: 1.Initiating some form of a financial support for OPEC with the necessary follow up. 2. Utilization of oil income in sectors organized to have the least susceptibility against income loss and the lowest impact on other sectors. 3. Reducing of oil production level in the local and global framework and starting in industrialization process. 4. Replacement of oil with natural gas at a faster rate. 5. improving the oil industry infrastructure for lowering production costs and increasing variety in products in light of country economic policies and occupational strategies. 6. Imposing self-reliance on development of oil-production technology

    2006-07-01

    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.

  17. Serbian oil sector: A new energy policy regulatory framework and development strategies

    International Nuclear Information System (INIS)

    Serbia has established a great part of new legislative and institutional framework as a basis for all energy sub-sectors' development in compliance with EU energy acquis. Main objectives of Serbian energy policy outlined in the new Energy Law are focused to increasing the energy supply security, energy efficiency, competitiveness of the energy market, use of renewable energy sources and environmental protection. Further steps of Serbia toward full EU membership concerning the new energy policy regulatory framework involve implementing and enforcing legislation. Besides considering the issue of Serbian energy policy and degree of its framework's alignment with the EU acquis, this paper provides an overview of new development strategies in the oil sector. The aim of Gazprom neft, a majority owner of the Petroleum industry of Serbia, is to increase crude oil production to 3 million tonnes, refining and sales volume of petroleum products to 5 million tonnes by 2020. Strategic development projects in crude oil and petroleum products transportation are: petroleum product pipeline construction in Serbia and Pan-European oil pipeline. The basic prerequisites for oil supply security, regarding the future high dependency of Serbian economy on imported oil, are establishment of the emergency oil stocks and diversification of supply sources. - Highlight: ► New energy policy regulatory framework significantly complied with EU acquis. ► Full EU membership requires implementing and enforcing new energy legislation. ► NIS-Gazpromneft has defined ambitious oil sector's development programmes to 2020. ► Supply security requires mandatory oil stocks and supply source diversification.

    2008-06-01

    Full Text Available The purpose of this article is to analyze the social actions undertaken by Brazilian retail companies. The study is justified by the need to have an on-going assessment of actions of this nature, bearing in mind that over the last 15 years many retail companies have been developing many social initiatives. The empirical data were taken from the database of information recorded by the Centro de Excelência no Varejo, of the Fundação Getulio Vargas. In order to assess the data, an adaptation of the James Austin (2000 model was made. Analysis of the data was predominantly exploratory, and involved the descriptive analysis, factor analysis, and cluster analysis. It was also made the cross analysis of the clusters generated with some of the variables. The results indicated a strong relationship between the social and economic value generated by the actions of companies and characteristics relating to their size, partnerships and the geographic spread of the actions.

  19. Restructuring the arrangements between government and state enterprises in the oil and mining sectors

    International Nuclear Information System (INIS)

    The article analyses the relationship between governments and state-owned enterprises (SOEs) in the oil and minerals sectors. The case is made that SOEs in these sectors have distinct peculiarities of behaviour, and are beset with specific difficulties in addition to typical problems common to SOEs in all sectors. The reasons for the uniqueness of SOEs in the oil and minerals sector stem mainly from their large size, their capacity to earn and borrow foreign currency, their strategic importance and other factors. The key to understanding and reforming state oil and mining enterprises lies in recognizing that their sub-optimal behaviour is often caused by conflicts within government regarding control of the SOE's financial flows, including the natural resource rent. These conflicts are frequently aggravated by the inappropriateness of fiscal arrangements between these SOEs and their governments. Guidelines for reforming these arrangements are offered, which, in some respects, differ considerably from those applicable to conventional state-owned enterprises outside the natural resources sector.

    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.

  1. Improved operations through manpower management in the oil sector

    International Nuclear Information System (INIS)

    The need for improved operations was never higher than today in the oil industry. The world's demand for energy, especially for oil and natural gas, is rising rapidly and for many years to come. In order to meet this rising demand and to keep price volatility to a minimum; oil companies worldwide are looking for ways to improve operations in order to achieve increased production with decreased costs. This paper describes data from Southern Area Oil Operations (SAOO); an organization within the Saudi Arabian Oil Company (ARAMCO), to show how manpower management can be used to achieve improved operations. For the years 1983 to 2004, manpower management in SAOO focused on addressing both the quantity and quality dimensions of manpower. First, the level of manpower gradually declined by 35% for both the Saudi Arab and Expatriate categories for the entire period. Expatriate labor is defined as labor in three main categories: US/Canadian, UK, and Asians and Other Arabs. Second, the level of training slowly increased to align manpower to better fit organizational functions and work responsibilities. Not only a number of new training and development programs were initiated but also the percentage of employees involved in such programs doubled from 4.5% in 1990 to 8.9% in 2004. Third, technology based initiatives such as the use of computers, Internet, and intranet were heavily introduced to employees in the last 10 yrs. Due to these three changes reduced costs and increased manpower efficiency were achieved. In the period 1983 to 2004 the total labor bill declined by 35% and Net Direct Expenditures NDE by 24% after adjusting for inflation and using 2004 dollars. Net Direct Expenditure NDE is defined by SAOO to be the summation of labor cost, material cost, invoices cost, and net service income. In addition two signs of improved efficiency of manpower were apparent in the same period. First, SAOO manpower, despite its smaller size, could actually sustain an increased

    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)

    State Secretary Robin Kaass of the Norwegian Ministry of Petroleum and Energy welcomed the participants. In his remarks he noted that the two countries share mutual challenges and opportunities in the North with regard to finding and recovering petroleum resources in a safe, environment-friendly manner. A large part of the world's remaining oil reserves are found in the Northern Areas, and the Barents Sea is one the most important fishing regions. It is crucial that petroleum activities are safe if the industry is to continue its credible co-existence with the fisheries industry. The tough climatic, operational and logistical conditions in the Barents Sea place great demands on technology, operational procedures and cooperation, MR. Kaass said. (AG)

    Full Text Available The air-dried aerial parts of Croton campestris, C. chaetocalyx, C. eriocladus, and C. glandulosus, with occurrence in the Eastern Brazilian Amazon, yielded essential oils, and their volatile constituents were analyzed by GC and GC-MS. Sesquiterpenes, both hydrocarbons and oxygenated, were the most highly represented classes in the oils: the former ranging from 55.3% to 85.1%, and the latter varying from 7.2% to 33.2%. The oils were separated into two groups using hierarchical cluster analysis whose main constituents were β-caryophyllene, germacrene D, γ-elemene, β-elemene, α-humulene and δ-elemene (Group A, C. campestris and C. eriocladus; and spathulenol, bicyclogermacrene, δ-elemene, germacrene D, β-caryophyllene and δ-cadinene (Group B, C. chaetocalyx and C. glandulosus. Percentage of sesquiterpene hydrocarbons was higher in Group A (83-85% than in Group B (55-63%. However, regarding the oxygenated sesquiterpenes, it was reversed, being bigger in Group B (28-33% than in Group A (7-8%. Percentage of similarity in Group A was 92% and in Group B it was 86%. These chemotaxonomic results showed a significant contribution for the better botanical knowledge of these four Croton species occurring in North Brazil.

    The aim of this research is to investigate the multiscale dynamic linkages between crude oil price and the stock market in China at the sector level. First, the Haar à trous wavelet transform is implemented to extract multiscale information from the original time series. Furthermore, we incorporate the vector autoregression model to estimate the dynamic relationship pairing the Brent oil price and each sector stock index at each scale. There is a strong evidence showing that there are bidirectional Granger causality relationships between most of the sector stock indices and the crude oil price in the short, medium and long terms, except for those in the health, utility and consumption sectors. In fact, the impacts of the crude oil price shocks vary for different sectors over different time horizons. More precisely, the energy, information, material and telecommunication sector stock indices respond to crude oil price shocks negatively in the short run and positively in the medium and long runs, terms whereas the finance sector responds positively over all three time horizons. Moreover, the Brent oil price shocks have a stronger influence on the stock indices of sectors other than the health, optional and utility sectors in the medium and long terms than in the short term. The results obtained suggest implication of this paper as that the investment and policymaking decisions made during different time horizons should be based on the information gathered from each corresponding time scale.

    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 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

    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.

    Coherent scatter echoes coming from the valley region (~150 km altitude) in the equatorial ionosphere during daytime have been detected by the Jicamarca radar in Peru for several decades (Basley, 1945). More recently, it was found that the vertical Doppler shift of these echoes corresponds to the vertical velocity of the F-region background plasma (Kudeki and Fawcett, 1993; Woodman and Villanueva,1995, Chau and Woodman, 2004). Jicamarca now uses observations of 150-km echoes to provide estimates of the diurnal variation of the equatorial vertical plasma drifts in addition to traditional incoherent scatter radar drift measurements. These 150-km echoes have also been observed in other longitude sectors (e.g. Tsunoda and Ecklund,2004; Patra et al., 2008). Additionally, these echoes have also been detected in a semi-routine basis with a small, low-power radar in Sao Luis, Brazil. Initial results of our analysis suggest that vertical plasma drifts can be estimated from these observations. These measurements combined with simultaneous measurements made by the Jicamarca radar and the C/NOFS satellite can help us better understand the day-to-day variability and longitudinal variation of equatorial electric fields. In this talk we will present examples of 150-km echoes observations made with the Sao Luis radar. We will describe how vertical drifts can be estimated from the observations and how the vertical drifts over Sao Luis compare with the drifts measured simultaneously at Jicamarca. These new measurements can provide important new information about the low-latitude electrodynamics, and consequently to the C/NOFS mission.

    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.

    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

    Full Text Available The world lives a context of energetic pre-crisis, and Brazil has discovered new big reserves of the “black gold”, which led to changing the regulation framework of its exploitation in the country. This paper focuses on the last change in that framework, in 1997, and tries to evaluate its effects in the production and its links to the rest of Brazilian economy. Using data derived from the I-O matrix in the supply side, and Balance of Payments data, we try to see if there were meaningful changes in the period 1998-2007 from the period 1990-1997 in terms of the oil sector linkage to the rest of the economy, technological modernization, its relation to employment and average earnings , and its impacts in the external insertion of the country (exports and dividends balance.

    This article extends the understanding of oil-stock market relationships over the last turbulent decade. Unlike previous empirical investigations, which have largely focused on broad-based market indices (national and/or regional indices), we examine short-term linkages in the aggregate as well as sector by sector levels in Europe using different econometric techniques. Our main findings suggest that the reactions of stock returns to oil price changes differ greatly depending on the activity sector. In the out-of-sample analysis we show that introducing oil asset into a diversified portfolio of stocks allows to significantly improve its risk-return characteristics. (author)

    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.

    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)

  8. Oil demand reduction in an oil crisis. Evaluation of oil demand-reducing measures for the transportation sector; Brandstofvraagreductie bij oliecrisis. Evaluatie van vraagreducerende maatregelen voor de transportsector

    Every IEA member state must have in place measures to reduce oil demand during oil supply emergencies. The transport sector offers significant opportunities to reduce oil demand with relatively limited impact on the overall economy. To determine which measures are useful in the Dutch situation, this report performs a quick scan of a number of demand restraint measures in the transport sector. The quick scan ranks measures by their effectiveness, feasibility, and efficiency. Based on the quick scan results, three measures have been selected for further research (Sunday driving ban, work-trip reduction, and carpooling). Additionally, the effects of price increases on oil demand have been examined. Five refineries and a large petrochemical industry sector are based in the Netherlands. Therefore, the shares of passenger road transport (20%) and freight road transport (12%) in the national oil demand are comparatively low. As a consequence an oil demand reduction in road transport of at least 20% to 30% is required to meet the national oil demand reduction target of 7% to 10% agreed within IEA. Price effects during an oil crisis are uncertain given limited research, and estimated to reduce oil demand from passenger road transport by 15% to 35% and oil demand from freight road transport by 10% to 25%. Given the uncertainty, this effect was halved to obtain a conservative estimate of 2% to 4% of national oil demand reduction as a result of price effects. A Sunday driving ban can lead to reductions of 50% to 80% of passenger travel on Sundays, leading to savings of 1% to 1.5% of national oil demand. Work-trip reduction policies can reduce worktrips by 10% and lead to reductions of 0.5% to 1% of total oil demand. Carpooling has the greatest potential, reducing work trips up to 30% and leading to 0% to 2.5% savings of national oil demand. The broad range of the latter estimate is due to the limited options available to influence motorists to share their vehicles with others

  10. The Kashagan Field: A Test Case for Kazakhstan's Governance of Its Oil and Gas Sector

    International Nuclear Information System (INIS)

    This study focuses on the factors behind Kazakhstan's decision to renegotiate the terms of the existing Production Sharing Agreements (PSAs) with International Oil Companies (IOCs), in the context of the development of the huge Kashagan oil field. The development of Kashagan, one of the largest and most recently discovered oil fields in Kazakhstan, is crucial for Kazakhstan's ambitions of becoming a global oil producer. Kazakhstan, which has the largest oil reserves in the Caspian Sea region, is the second largest regional producer after Russia in the former Soviet Union. The country's potential for oil exports is also strategically significant as a future source of non- OPEC supplies. Amongst the CIS states, Kazakhstan is considered one of the most open countries for foreign investments. International projects in the form of Joint Ventures, Production Sharing Agreements (PSAs) or exploration/field concessions have brought foreign investments into the country's natural resources sector, particularly in the oil and gas industry. However, new developments have recently taken place, which have marked a shift in the Kazakh government's approach towards foreign investment in its energy sector. This study will therefore examine the following issues: - Kazakhstan's plans to abandon the practice of attracting foreign investments in its energy sector through new PSAs. - The recent entry of state-controlled KazMunaiGaz into the consortium operating over the Kashagan field and its impact on IOCs. - The impact of high oil prices on the negotiating power of producer states in the context of Kazakhstan's new stance on PSAs. Specifically, this study will focus on the following key factors, which will seek to further explain the changes in Kazakhstan's attitude toward the Kashagan PSA2: - Operational factors - management of the project, development strategy, cost estimates, levels of production and export markets. - Consortium factors - the relative strength of the investment

    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)

    Sectoral greenhouse gas offsets can provide the same incentives for emissions reductions as a carbon tax or a cap-and-trade program, with a focus on rewards rather than costs. This paper develops a pilot analysis of such offsets using relatively transparent quantitative methods to estimate a business-asusual (BAU) emissions path for the gas and basic petrochemical subsidiary of Mexico’s national oil company, Pemex. This BAU path, in turn, may be used as a basis for monetizing emissions reduct...

    Full Text Available The internationalization of companies refers to a strategy to get greater presence in the international market. As the companies need to make use of strategical resources for their insertion in the international market, was searched to answer: Is there a relation between the evolution of the strategical resources and the strategies of internationalization in great exporting companies of the Brazilian footwear sector? For the theoretical base were used the classifications of the resources of Fahy (2002 and the strategies of internationalization of Sharma and Erramilli (2004. The study searched to rescue the dynamic character of the Resouce-based View. The method of the research was the quantitative and explicative nature. The data were collected from 2004 to 2005, with 15 great exporting companies of the Brazilian footwear sector and had been analyzed by the Cluster Analysis in the entrance in the international market, in the current situation and in 2010. It was concluded that the companies which use more complex strategies of internationalization, at the entrance moment and in the future, consider more strategical the capabilities, then the tangible resources and finally the intangible resources. However, in the current situation, they consider more strategical the capabilities, then the intangible resources and finally, the tangible resources.

    2009-07-01

    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)

  15. Applying maintenance strategies from the space and satellite sector to the upstream oil and gas industry: A research agenda

    International Nuclear Information System (INIS)

    Practitioners from both the upstream oil and gas industry and the space and satellite sector have repeatedly noted several striking similarities between the two industries over the years, which have in turn resulted in many direct comparisons in the media and industry press. The two sectors have previously worked together and shared ideas in ways that have yielded some important breakthroughs, but relatively little sharing or cross-pollination has occurred in the area of asset maintenance. This is somewhat surprising in light of the fact that here, too, the sectors have much in common. This paper accordingly puts forward the viewpoint that the upstream oil and gas industry could potentially make significant improvements in asset maintenance—specifically, with regard to offshore platforms and remote pipelines—by selectively applying some aspects of the maintenance strategies and philosophies that have been learned in the space and satellite sector. The paper then offers a research agenda toward accelerating the rate of learning and sharing between the two industries in this domain, and concludes with policy recommendations that could facilitate this kind of cross-industry learning. - Highlights: • Oil and gas industry and space and satellite sector are very similar in several important ways. • Paper suggests that oil and gas industry should adopt best maintenance practices from satellite sector. • Research agenda outlined to accelerate the rate of learning and sharing between the two industries

    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. PMID:25949264

    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.

  3. The strategy of the key players in the African oil sector (the Gulf of Guinea)?

    International Nuclear Information System (INIS)

    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)

    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.

    The paper presents 5 methodological aspects for the historic land use change accountability to compare 2 databases: the Historical Database on the Global Environment of RIVM, National Institute of Public Health and the Environment, adapted by the IVIG, International Virtual Institute of Global Change of the Federal University of Rio de Janeiro, named HYDE/IVIG and the Brazilian National Institute of Spatial Research database, named INPE database. The 5 aspects here considered are geographic limits; scale; basic methodology; deforestation concept; vegetal classification. It also presents their importance for the results of the calculus of deforested areas in the Brazilian Legal Amazon case. The use of the 2 databases information for carbon emissions calculation showed to be useful in terms of magnitude but not for qualitative analysis. The calculus of deforested areas is approximately similar for the period analyzed. According to HYDE/IVIG, the Brazilian Legal Amazon land use changes representing agriculture and pasture lands, account 422,070 km{sup 2}, between 1750 and 1990 and the natural areas modified were originally classified as 3 types: tropical forest, wooded tropical forest and savanna. According to INPE, the cumulative Brazilian Legal Amazon deforestation until 1990 accounts 415,000 km{sup 2} and the natural areas modified were originally classified as 9 types. It means that different carbon contents by unit of deforestation have to be taken into account for the carbon emissions calculus. These numbers show the compatibility of the databases in terms of magnitude but the quality of the information present huge differences. (author)

  6. Morphological analysis of thermoplastic starch films and montmorillonite (TPS/MMT) using vegetable oils of Brazilian Cerrado as plasticizers

    International Nuclear Information System (INIS)

    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)

    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)

    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.

    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.

  11. Second to none: Brazilian, Mexican oil giants turn to Canadian satellite system for eagle eye on offshore spills

    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.

    The present case study reports the unusual noon-time electron density bite-out events during 12th-18th April 2004 around the anomaly crest locations which are not observed over the geomagnetic equator. These bite-out events at the crest locations occurred on three consecutive days under solar and geomagnetically quiet conditions over the Indian and Brazilian sectors. The bite-out events are observed with a delay of two days over the Brazilian sector when compared with those in the Indian sector. The duration of these TEC bite-outs is found to vary around 5 h in the Indian sector while it is around 3 h in the Brazilian sector. Over Raipur in the Indian sector, the bite-out is found to be very strong (~30 TECU) on 13th April 2004, where the TEC drops to nearly 50% of the corresponding day maximum TEC. The diurnal variations of dTEC have also shown significant differences during the occurrence of noon-time TEC bite-outs. Simultaneous Equatorial Electrojet (EEJ) variations over the Indian and Brazilian sectors have also been studied. The ionosonde data over the equatorial and anomaly crest locations has been analyzed to understand the F-layer behavior during the occurrence of TEC bite-outs. Significant drop in the F-layer peak density and heights are observed during the TEC bite-outs while the minimum height of the bottom side F-layer do not show considerable differences. Further, the variations of vertical electron density profiles are studied to explain the F-layer characteristics that resulted in the noon-time bite-outs over the anomaly crest locations.

    This paper presents an investigation of geomagnetic storm effects in the equatorial and low latitude F-region in the Brazilian sector during the intense geomagnetic storm on 18 August, 2003 (SSC 14:21 UT on 17/08; ΣKp = 52+; Ap = 108; ∣Dst∣ max = 168 at 1600 UT on 18/08). Simultaneous ionospheric sounding measurements from two stations, viz., Palmas (10.2°S, 48.2°W; dip latitude 5.7°S) and Sao Jose dos Campos (23.2°S, 45.9°W; dip latitude 17.6°S), Brazil, are presented for the nights of 16-17, 17-18 and 18-19 August, 2003 (quiet, disturbed and recovery phases). Both stations are equipped with the Canadian Advanced Digital Ionosonde (CADI). Quiet and disturbed conditions of the F-region ionosphere are compared using data collected from the two stations. The relationship between magnetospheric disturbance and low-latitude ionospheric dynamics, and generation of ionospheric irregularities are discussed. On the disturbed nights (17-18 and 18-19 August), the low latitude station S. J. Campos showed strong enhancements in the F-region critical frequency (foF2), whereas the near equatorial station Palmas showed strong uplifting of the F-layer about 1 h earlier. Normally during the June solstice months (May-August) in the Brazilian sector, large-scale ionospheric irregularities in form of plasma bubbles are rarely observed. On the night of 17-18 August, ionsospheric sounding observations at Palmas showed the presence of bottomside spread-F, whereas on the night of 18-19 August, the observations at Palmas and S. J. Campos showed the presence of plasma bubbles when the storm recovery phase had just started. The complementary GPS data available from several stations in the "Rede Brasileira de Monitoramento Continuo de GPS (Brazilian Network for Continuous GPS Monitoring)" are used to obtain the vertical total electron content (VTEC) and the rate of change of TEC per minute on UT days 18 and 19 August, 2003 and presented. Also, several global ionospheric TEC maps

    2008-07-01

    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)

  17. A questão do investimento no Setor Elétrico Brasileiro: reforma e crise The investment in the Brazilian power sector: reform and crisis

    Directory of Open Access Journals (Sweden)

    João Lizardo de Araújo

    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.

    Norway has administered its petroleum resources using three distinct government bodies: a national oil company engaged in commercial hydrocarbon operations; a government ministry to direct policy; and a regulatory body to provide oversight and technical expertise. Norway's relative success in managing its hydrocarbons has prompted development institutions to consider whether this 'Norwegian Model' of separated government functions should be recommended to other oil-producing countries. By studying ten countries that have used widely different approaches in administering their hydrocarbon sectors, we conclude that separation of functions is not a prerequisite to successful oil sector development. Countries where separation of functions has worked are characterized by the combination of high institutional capacity and robust political competition. Unchallenged leaders often appear able to adequately discharge commercial and policy/regulatory functions using the same entity, although this approach may not be robust against political changes. Where institutional capacity is lacking, better outcomes may result from consolidating commercial, policy, and regulatory functions until such capacity has further developed. Countries with vibrant political competition but limited institutional capacity pose the most significant challenge for oil sector reform: Unitary control over the sector is impossible but separation of functions is often difficult to implement. - Highlights: > The 'Norwegian Model' separates commercial, policy, and regulatory functions in oil. > We study ten oil-producing countries to assess the separation of functions model. > The model is useful where there is institutional capacity and political competition. > Consolidation of functions can work better when political power is concentrated. > Countries with low capacity may also be better off consolidating functions.

    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.

  4. Life cycle GHG emissions from Malaysian oil palm bioenergy development: The impact on transportation sector's energy security

    International Nuclear Information System (INIS)

    Malaysia's transportation sector accounts for 41% of the country's total energy use. The country is expected to become a net oil importer by the year 2011. To encourage renewable energy development and relieve the country's emerging oil dependence, in 2006 the government mandated blending 5% palm-oil biodiesel in petroleum diesel. Malaysia produced 16 million tonnes of palm oil in 2007, mainly for food use. This paper addresses maximizing bioenergy use from oil-palm to support Malaysia's energy initiative while minimizing greenhouse-gas emissions from land-use change. When converting primary and secondary forests to oil-palm plantations between 270-530 and 120-190 g CO2-equivalent per MJ of biodiesel produced, respectively, is released. However, converting degraded lands results in the capture of between 23 and 85 g CO2-equivalent per MJ of biodiesel produced. Using various combinations of land types, Malaysia could meet the 5% biodiesel target with a net GHG savings of about 1.03 million tonnes (4.9% of the transportation sector's diesel emissions) when accounting for the emissions savings from the diesel fuel displaced. These findings are used to recommend policies for mitigating GHG emissions impacts from the growth of palm oil use in the transportation sector. - Research highlights: → We modeled greenhouse gas emissions in the production of palm-biodiesel. → Five land types were included to model emissions associated with land-use change. → Land-use change has the biggest impact on the emissions in making palm-biodiesel. → Emissions from fertilizer use and effluent treatment are still significant. → At 5% biodiesel grown on suitable lands Malaysia would obtain an emissions savings.

    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

  8. Forests and global warming mitigation in Brazil: opportunities in the Brazilian forest sector for responses to global warming under the 'clean development mechanism''

    International Nuclear Information System (INIS)

    The Kyoto Protocol created global warming response opportunities through the clean development mechanism that allow countries like Brazil to receive investments from companies and governments wishing to offset their emissions of greenhouse gases. Brazil has a special place in strategies for combating global warming because its vast areas of tropical forest represent a potentially large source of emissions if deforested. A number of issues need to be settled to properly assign credit for carbon in the types of options presented by the Brazilian forest sector. These include definition of the units of carbon (permanent sequestration versus carbon-ton-years, the latter being most appropriate for forest options), the means of crediting forest reserve establishment, adoption of discounting or other time-preference weighting for carbon, definition of the accounting method (avoided emissions versus stock maintenance), and mechanism to allow program contributions to be counted, rather than restricting consideration to free-standing projects. Silvicultural plantations offer opportunities for carbon benefits, but have high social impacts in the Brazilian context. Plantations also inherently compete with deforestation reduction options for funds. Forest management has been proposed as a global warming response option, but the assignment of any value to time makes this unattractive in terms of carbon benefits. However, reduced-impact logging can substantially reduce emissions over those from traditional logging practices. Slowing deforestation is the major opportunity offered by Brazil. Slowing deforestation will require understanding its causes and creating functional models capable of generating land-use change scenarios with and without different policy changes and other activities. Brazil already has a number of programs designed to slow deforestation, but the continued rapid loss of forest highlights the vast gulf that exists between the magnitude of the problem and the

  11. Oil policies and privatization strategies in Mexico: implications for the petrochemical sector and its production spaces

    International Nuclear Information System (INIS)

    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 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.

    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.

    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.

    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.

    Biofuels development in Brazil is a key factor for the environment and sustainable development of the country. Brazil has great potential of available areas and has favourable climate and geography for biofuel production, such as palm oil, soy, sugar cane, etc. This research aims to evaluate palm oil production and expansion in Para state, in the north of Brazil and also Amazonian territory. Degraded land will be evaluated through remote sensing, because palm oil crops should be placed in these lands, and secondly, expansion scenarios would be created. This PhD research will be a decision support tool for public policies.

    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

    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 microg/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.

    Essential oils obtained from leaves of 29 medicinal plants commonly used in Brazil were screened against 13 different Escherichia coli serotypes. The oils were obtained by water-distillation using a Clevenger-type system and their minimal inhibitory concentration (MIC) were determined by microdilution method. Essential oil from Cymbopogon martinii exhibited a broad inhibition spectrum, presenting strong activity (MIC between 100 and 500 microg/mL) against 10 out of 13 Escherichia coli serotypes: three enterotoxigenic, two enteropathogenic, three enteroinvasive and two shiga-toxin producers. C. winterianus inhibited strongly two enterotoxigenic, one enteropathogenic, one enteroinvasive and one shiga-toxin producer serotypes. Aloysia triphylla also shows good potential to kill Escherichia coli with moderate to strong inhibition. Other essential oils showed antimicrobial properties, however with a more restricted action against the serotypes studied. Chemical analysis of Cymbopogon martinii essential oil performed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS) showed the presence of compounds with known antimicrobial activity, including geraniol, geranyl acetate and trans-cariophyllene, which tested separately, indicated geraniol as antimicrobial active compound. The significant antibacterial activity of Cymbopogon martinii oil suggests that they could serve as a source for compounds with therapeutic potential. PMID:17210236

    Herbal extracts have been investigated as an alternative for parasite control, aiming to slow the development of resistance and to obtain low-cost biodegradable parasiticides. The goal of this study was to evaluate the efficacy, in vitro, of 11 essential oils from Brazil on reproductive efficiency and lethality of the cattle tick Rhipicephalus (Boophilus) microplus. The effects of oils extracted from Curcuma longa, Zingiber officinale, Lippia alba, Lippia gracilis, Lippia origanoides, Lippia sidoides, Mentha arvensis, Mentha piperita, Croton cajucara (white and red), and Croton sacaquinha on ticks were investigated by the Immersion Test with Engorged Females (ITEF) and the modified Larval Packet Test (LPT). Distilled water and 2% Tween 80 were used as control treatments. Chemical analysis of the oils was done with gas chromatography coupled with mass spectrometry. Analysis of the in vitro tests using Probit (SAS program) allowed the calculation of lethal concentrations (LCs). Lower reproductive efficiency indexes and higher efficacy percentages in the ITEF were obtained with the oils extracted from C. longa (24 and 71%, respectively) and M. arvensis oils (27 and 73%, respectively). Lower LC50 was reached with C. longa (10.24 mg/mL), L. alba (10.78 mg/mL), M. arvensis (22.31 mg/mL), L. sidoides (27.67 mg/mL), and C. sacaquinha (29.88 mg/mL) oils. In the LPT, species from Zingiberaceae and Verbenaceae families caused 100% lethality at 25 mg/mL, except for L. sidoides. The most effective oils were from C. longa, L. gracilis, L. origanoides, L. alba, and Z. officinale. The LC50 and LC90 were, respectively: 0.54 and 1.80 mg/mL, 3.21 and 7.03 mg/mL, 3.10 and 8.44 mg/mL, 5.85 and 11.14 mg/mL, and 7.75 and 13.62 mg/mL. The efficacy was directly related to the major components in each essential oil, and the oils derived from Croton genus presented the worst performance, suggesting the absence of synergistic effect among its compounds. Since C. longa, containing 62

    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)

    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.

  10. Data as an asset: What the oil and gas sector can learn from other industries about “Big Data”

    International Nuclear Information System (INIS)

    The upstream oil and gas industry has been contending with massive data sets and monolithic files for many years, but “Big Data” is a relatively new concept that has the potential to significantly re-shape the industry. Despite the impressive amount of value that is being realized by Big Data technologies in other parts of the marketplace, however, much of the data collected within the oil and gas sector tends to be discarded, ignored, or analyzed in a very cursory way. This viewpoint examines existing data management practices in the upstream oil and gas industry, and compares them to practices and philosophies that have emerged in organizations that are leading the way in Big Data. The comparison shows that, in companies that are widely considered to be leaders in Big Data analytics, data is regarded as a valuable asset—but this is usually not true within the oil and gas industry insofar as data is frequently regarded there as descriptive information about a physical asset rather than something that is valuable in and of itself. The paper then discusses how the industry could potentially extract more value from data, and concludes with a series of policy-related questions to this end. -- Highlights: •Upstream oil and gas industry frequently discards or ignores the data it collects •The sector tends to view data as descriptive information about the state of assets •Leaders in Big Data, by stark contrast, regard data as an asset in and of itself •Industry should use Big Data tools to extract more value from digital information

    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.

    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)

  13. Advancing strategic environmental assessment in the offshore oil and gas sector: Lessons from Norway, Canada, and the United Kingdom

    International Nuclear Information System (INIS)

    Abstract: Strategic environmental assessment (SEA) for offshore oil and gas planning and development is utilized in select international jurisdictions, but the sector has received limited attention in the SEA literature. While the potential benefits of and rationale for SEA are well argued, there have been few empirical studies of SEA processes for the offshore sector. Hence, little is known about the efficacy of SEA offshore, in particular its influence on planning and development decisions. This paper examines SEA practice and influence in three international offshore systems: Norway, Atlantic Canada and the United Kingdom, with the intent to identify the challenges, lessons and opportunities for advancing SEA in offshore planning and impact assessment. Results demonstrate that SEA can help inform and improve the efficacy and efficiency of project-based assessment in the offshore sector, however weak coordination between higher and lower tiers limit SEA's ability to influence planning and development decisions in a broad regional environmental and socioeconomic context. - Highlights: ► SEA can inform and improve the efficacy and efficiency of project EA offshore ► Scope and deliverables of SEA offshore often differ from stakeholder expectations ► Considerable variability in influence of SEA output beyond licensing decisions ► Sector-based SEA offshore is often too restrictive to generate expected benefits

The objective of this research is not to present those achievements, but to analyze the sources of growth and changes in the production structure. Further, it aims to determine whether the development policies have accomplished the main goal which is to sustain growth and to diversify the production structure. The Chenery typical patterns approach is used to analyze growth and structural changes. The results indicate that the economic production structure is extremely dependent on income from exports of oil. Also, the results show the economy moved away from the typical pattern and became less diversified. The time series estimates of growth indicate that income growth elasticities with respect to all sectors were inelastic. Apparently, the growth in income, contrary to what is expected by the typical growth approach, was not due to a successful transformation in the economic structure, but was mainly due to the growth of oil income. To analyze the role of government policies in directing growth and structural changes, a multi-sectoral model is constructed, and multiplier analyses carried out. The study finds, first, that the production structure is vulnerable to changes in world oil demand. Second, the manufacturing base is very limited, and the economy is dependent on imports of consumer goods and capital goods to satisfy final demand and supply side respectively. Third, the results suggest that while government infrastructure investment is stimulating private investment, the non-infrastructure investment is substituting for private investment. Fourth, government policies have not been able to soften the adjustment processes that resulted from the shocks from declining oil prices on the production structure. Finally, most investment has been in physical and social infrastructure and not in productive

    Full Text Available Purpose. This study analyzes the oil industry, gas and biofuels in order to identify associations between corporate governance practices with capital structure, risk and performance.Methodology. These data were verified through 3SLS models (Three-Stage Least Squares. For this, we used a data set composed of 19 companies, for a panel data analysis in the period 2005-2009.Findings. The results suggest a negative association between leverage and corporate governance company level, supporting the substitution hypothesis, according to which the leverage works as a governance substitute. Also they did not reject the hypothesis that the greater the governance practices, greater market performances and accounting of these companies, as well as reduces the market risk.Limitations. The main limitation of this research is the sample size, 19 companies, with particular focus on an industry, reducing the generalizability of the results.Originality/Value. This study sought to contribute to the understanding of the relationship between corporate governance, capital structure, performance and risk; specifically for the oil, gas and biofuels in Brazil, an important and understudied emerging market.

From those indicators a multicriteria analysis is applied to a case study, allowing to learn simultaneously the influence of environmental and social questions on the decision making of the brazilian electric sector expansion.

  2. Improvement in supply chain management for oil and gas sector using drag reduction theory

    International Nuclear Information System (INIS)

    Supply chain management is an integrative philosophy about managing the flow of distribution channels from supplier to the consumer. PARCO, an oil and gas company in Pakistan has three existing pipelines. Out of three, two pipelines are running parallel from Karachi to Mehmood kot. One pipeline is of crude oil and meeting the demand of PARCO refinery while second pipeline is of High Speed Diesel (HSD) and third pipeline is of (HSD and Kerosene) running from Mehmood Kot to Machhike (Sheikhupura). PARCO supply petroleum products from Shikarpur, Mehmood Kot, Faisalabad and Machhike to oil marketing companies (OMCs) as per their share, standard and demand. The purpose of these pipelines is to meet the country demand for petroleum products at various locations all over Pakistan. In the peak season when OMCs have high demand and receipt of product from PARCO pipelines are less, there is a need to enhance the flow rate of oil inside the PARCO pipelines to fulfill the demand of OMCs. This could be done economically by the application of drag reduction theory. So by injecting drag reducer, dragging of the oil inside the pipeline could appreciably be reduced thereby improving the pumping of oil. (author)

    Organizational ergonomics refers to the optimization of social technical systems, including their organizational structures, policies and processes. The relevant topics include communications, management of resources, work projects, temporal organization of work, team work, participative project, new work paradigms, cooperative work, organizational culture, network organizations and quality management (IEA, 2000). The purpose of this study was the reorganization of the methods and processes of the occupational health sector (SMS/SO - Portuguese acronym of the area) of a petrochemical company. The work involved thirty professionals: a coordinator, two occupational physicians, one cardiologist, one occupational dentist, two occupational nurses, eleven occupational health technicians, one social worker, one nutritionist, one phonoaudiologist, one ophthalmologist, one biochemist, two ergonomists, three administrative assistants, one administrator and one psychologist, during a six-month period. The methodology that was used sought to establish a cooperative alliance focused on change, transformation and acquisition of skills, reflecting directly on the attitudes and performance of the leaderships and their work teams. In addition to the feedback practice, the following supporting tools were used for the study's success: "Functional Polyvalence Matrix", "Management of Failures", 5W2H", "6M", "5 Why" and "process mapping". The intended results after the organization ergonomics restructuring process will allow the leader to help his or her team to make a diagnosis of the problems, identify options, develop strategies, establish targets and action plans, remove barriers, review contexts and implement the business management fundaments: planning, organization, management, coordination and control. The transformation possibilities allow us to consider some hypothesis: Before: Focus only on results. After: Engage collaborators to create sustainable results. Before: Operating

    The extraction of oil from baru almonds produces a waste that carries part of their nutritional qualities and antioxidants. It can be used to produce partially deffated baru flour (PDBF). We aimed to evaluate the applicability of PDBF and the effect of the addition of xanthan gum (XG) to produce gluten free cakes. Cakes were prepared with 100% wheat flour (WF cake) and with 100% PDBF and four different levels of XG (0%-PDBF cake, 0.1%-X1, 0.2%-X2 and 0.3%-X3 cakes), and evaluated for composition, antioxidants, moisture, specific volume, texture and sensory acceptance. PDBF cakes showed lower carbohydrate values, but higher protein, lipids, calories and antioxidant contents. They were rich in fiber, as well as iron, zinc and copper. The replacement of WF by PDBF resulted in an increased hardness and adhesiveness and a decreased cohesiveness, elasticity and moisture. Chewiness of X2 cake was similar to that of WF cake. X2 and X3 cakes showed specific volume closer to that of WF cake. No difference was found among the treatments for texture and appearance acceptances. Flavor of X2 and X3 cakes were more accepted than WF cake. Acceptance of all cakes were in the liking region of hedonic scale. PBDF associated to XG is a feasible option to substitute WF in gluten free cake, improving its nutritional quality. PMID:25577329

  7. Labour market assessment of the offshore oil and gas industry supply and service sector in Newfoundland and Labrador

    International Nuclear Information System (INIS)

    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

    The chemical composition and antimicrobial activity of essential oils obtained from three Brazilian plant species-leaves and branches of Eremanthus erythropappus (Asteraceae), leaves of Plectranthus barbatus, and leaves of P. amboinicus (Lamiaceae)-were determined. Analysis by GC/MS and determination of Kovats indexes both indicated δ-elemene (leaves-42.61% and branches-23.41%) as well as (-)-α-bisabolol (leaves-24.80% and stem bark-66.16%) as major constituents of E. erythropappus essential oils. The main components of leaves of P. barbatus were identified as (Z)-caryophyllene (17.98%), germacrene D (17.35%), and viridiflorol (14.13%); whereas those of leaves of P. amboinicus were characterized as p-cymene (12.01%), γ-terpinene (14.74%), carvacrol (37.70%), and (Z)-caryophyllene (14.07%). The antimicrobial activity against yeasts and bacteria was assessed in broth microdilution assays to determine the minimum inhibitory concentration (MIC) necessary to inhibit microbial growth. In addition, the crude oil of branches of E. erythropappus was subjected to chromatographic separation procedures to afford purified (-)-α-bisabolol. This compound displayed biological activity against pathogenic yeasts, thus suggesting that the antimicrobial effect observed with crude oils of E. erythropappus leaves and branches may be related to the occurrence of (-)-α-bisabolol as their main component. Our results showed that crude oils of Brazilian plants, specifically E. erythropappus, P. barbatus, and P. amboinicus and its components, could be used as a tool for the developing novel and more efficacious antimicrobial agents.

  12. Oil price movements and the Arabian Gulf economies: a sectoral analysis

    International Nuclear Information System (INIS)

    Six of the Arabian Gulf countries are founding members of the Gulf Cooperation Council (GCC) and are known as GCC member states. Jointly, in 1997, they held close to 46 per cent of the world crude oil reserves and derived a major part of their national income from oil revenues. The study analyzes the response of these states to the changes in world oil prices over two major time periods: a 1972-1980 period (Phase I) of steadily increasing prices and a 1981-1996 period (Phase II) of steadily declining and then weakly recovering prices. Phase I is characterized in the member States by an unprecedented economic boom and Phase II by an adjustment to strong recessionary pressures. (Author)

  17. 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.

  20. Role of the provincial government of Saskatchewan in encouraging growth in the oil and gas sector

    International Nuclear Information System (INIS)

    The year 1996 was one of the most successful years for the oil and gas industry in Saskatchewan. In the view of the author this may be said to be due, at least in part, to the provincial government's efforts to establish and implement policies that stimulate economic activity. Government regulation is essential to ensure safe and sensible development, a level playing field for all participants, and to ensure that residents of the province receive a fair share of the benefits of resource development. Some of the positive government actions taken in 1996 include: revisions to the royalty rate structure, simplification of the natural gas administration system, a program to encourage exploration in less-explored areas, re-balancing electrical rates, and a review of all regulations with the goal of streamlining or eliminating them. New technologies such as horizontal drilling were also encouraged. Issues presently before the government include postage stamp tolls, global warming, greenhouse gas emissions and environmental concerns from farmers. On the whole, the oil and gas industry received high marks for taking a responsible approach to self-regulation, but continued public support will depend on how well the industry addresses environmental concerns and demonstrates the benefits of oil and development to the people

    British Columbia is reviewing the existing moratorium on offshore oil and gas development and has commissioned the report BC Offshore Oil and Gas Technology Update. The report suggests that there are no specific design, geohazard or environmental issues that would preclude the development of offshore oil and gas in British Columbia, but there are many regulatory and socio-political barriers that need to be addressed. This paper addresses issues related to marine engineering, such as how can engineering companies get involved. Some of the potential areas of involvement for engineers is in the development phase, development of the process for regulatory reviews, and establishment of agreements with First Nations. Marine engineering will also be necessary for 4 phases, exploration, development, production and decommissioning. The exploration phase will involve initial seismic surveys, and licensing round. The development phase will involve more concentrated geological surveys, interpretation, initial well drilling and well planning, plus environmental assessments. The production phase will provide opportunity for marine operations in terms of equipment maintenance, repair and upgrade. The decommissioning phase is of short duration and will require expertise in the areas of decommissioning and removal of facilities. 6 figs.

    In recent years, agronomical researchers began to cultivate several olive varieties in different regions of Brazil to produce virgin olive oil (VOO). Because there has been no reported data regarding the phenolic profile of the first Brazilian VOO, the aim of this work was to determine phenolic contents of these samples using rapid-resolution liquid chromatography coupled to electrospray ionisation time-of-flight mass spectrometry. 25 VOO samples from Arbequina, Koroneiki, Arbosana, Grappolo, Manzanilla, Coratina, Frantoio and MGS Mariense varieties from three different Brazilian states and two crops were analysed. It was possible to quantify 19 phenolic compounds belonging to different classes. The results indicated that Brazilian VOOs have high total phenolic content because the values were comparable with those from high-quality VOOs produced in other countries. VOOs from Coratina, Arbosana and Grappolo presented the highest total phenolic content. These data will be useful in the development and improvement of Brazilian VOO. PMID:25306359

    Oil and gas companies are becoming increasingly accountable for the safety and protection of workers. This article provided details of Bell's Risk Management Solution Suite, which was designed to meet the unique needs of the oil and gas sector. Working collaboratively with partners, Bell is now providing a range of applications, including Ekahau's Real Time Location System (RTLS) and the telephone-based Enhanced Contact Solutions (ECS). Both applications help to reduce the risk of both personal and organizational liability. The ECS application allows employees to quickly file a work plan with a defined schedule and timeline. If the employee is stranded or unable to make contact, the application will notify additional personnel. The hosted solution can work with any phone line communication device and is not reliant on an existing Bell customer relationship. The suite's RTLS technology operates within a wireless local area network (WLAN). Using specially designed location tags attached to employees and contractors, the RTLS can track personnel in real time across an entire facility to enhance site safety and security. The system can also be used to create geo-fences to prevent unwanted personnel from visiting higher security zones. The system is capable of tracking more than 10,000 objects, and can also complete approximately 600 location transactions per second. Once installed, the WLAN system enables employees to use laptops and mobile devices around the plant or work site, allowing remote workers to secure access to internal systems and data. It was concluded that the suite will allow oil and gas operators to practice excellent risk management through enhanced connectivity. 2 figs.

    , 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.

    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)

  7. Quality control in the analysis of radioactivity from the oil exploration sector

    International Nuclear Information System (INIS)

    The presence of 226Ra, 228Ra and 210Pb in the production of oil is now a well-known phenomenon. An effort has been undertaken to establish quality control procedures and to produce an in-house reference material. Scale build-up has a significant amount of iron, barium and strontium and as such self-attenuation of photons, especially the 46.5 keV photon from 210Pb can significantly underestimate the radioactivity concentration. A procedure was developed to prepare an in-house standard using only a 20-g sample of scale obtained from west Texas. An evaluation of the homogeneity, counting procedures and determination of the self-attenuation factors are presented. (author)

    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)

  11. Toxicity assessment of approved drilling mud additives in the oil and gas sector

    International Nuclear Information System (INIS)

    Approval by Alberta Energy and Utilities Board of the surface disposal of drilling fluids has been announced under the jurisdiction of the Drilling Waste Management guideline. Disposal is allowed without toxicity testing if the fluid is consistent with water based materials as opposed to oil based, and all additives have been pre-approved. The list of additives is compiled by the Petroleum Services Association of Alberta and additives must pass the bacterial luminescence test to be included. This paper examines the question of whether the bacterial luminescence test provides an adequate degree of ecological protection for surface disposal. The study consisted of subjecting over 90 per cent of the additives to a multitrophic level examination (microbes, plants, invertebrates, fish), followed by ranking and consolidation into a toxicity index for comparison to the bacterial luminescence test results. Overall, there was good agreement and the results support the multitrophic level approach because a number of the additives cannot be adequately evaluated by the bacterial luminescence alone

    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.

    Every IEA member state must have in place measures to reduce oil demand during oil supply emergencies. The transport sector offers significant opportunities to reduce oil demand with relatively limited impact on the overall economy. To determine which measures are useful in the Dutch situation, this report performs a quick scan of a number of demand restraint measures in the transport sector. The quick scan ranks measures by their effectiveness, feasibility, and efficiency. Based on the quick scan results, three measures have been selected for further research (Sunday driving ban, work-trip reduction, and carpooling). Additionally, the effects of price increases on oil demand have been examined. Five refineries and a large petrochemical industry sector are based in the Netherlands. Therefore, the shares of passenger road transport (20%) and freight road transport (12%) in the national oil demand are comparatively low. As a consequence an oil demand reduction in road transport of at least 20% to 30% is required to meet the national oil demand reduction target of 7% to 10% agreed within IEA. Price effects during an oil crisis are uncertain given limited research, and estimated to reduce oil demand from passenger road transport by 15% to 35% and oil demand from freight road transport by 10% to 25%. Given the uncertainty, this effect was halved to obtain a conservative estimate of 2% to 4% of national oil demand reduction as a result of price effects. A Sunday driving ban can lead to reductions of 50% to 80% of passenger travel on Sundays, leading to savings of 1% to 1.5% of national oil demand. Work-trip reduction policies can reduce worktrips by 10% and lead to reductions of 0.5% to 1% of total oil demand. Carpooling has the greatest potential, reducing work trips up to 30% and leading to 0% to 2.5% savings of national oil demand. The broad range of the latter estimate is due to the limited options available to influence motorists to share their vehicles with others

    Full Text Available With regard to changing business environment over the last two decades, risk management has become a main area of business practice to define, analyse and control uncertainties. It necessitates identifying critical areas of planning and actions which must be considered to achieve effectiveness named Critical Success Factors (CSFs. The aim of this study is to classify and prioritize the CSFs necessary for risk management in oil and gas sector in Iran. In order to do the research a comprehensive set of CSFs were selected in the existing streams of research. Accordingly ten CSFs were identified named commitment and support, communication, culture, structure, IT, process management, resources, training, strategy and measurement. The quantitative method was employed in data collection by using questionnaire. Then to evaluate the influence of each CSF on risk management, an empirical study was conducted by Principal Components Analysis (PCA by using SPSS package to classify CSFs and extract main factors. The CSFs are categorized into three components; management, operation and context. Then, the extent to which each CSF impacts on risk was measured through a structural model by using Confirmatory Factor Analysis (CFA by applying Smart PLS package. Consequently, the obtained results indicated that two components; management and context had eigen value greater than one, acceptable reliability (Cronbach’s alpha and Dillion-Goldstein's ρ (D.G.'s ρ >0.7 and validity (AVE>0.5.( Furthermore, this framework showed a satisfactory fitness (GoF = 0.76.

    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

    Geostatistical techniques were used to evaluate the differences in the geochemistry of metals in the marine sediments along the Eastern Brazilian continental margin along the states of Ceará and Rio Grande do Norte (Northeastern sector) and Espírito Santo (Southeastern sector). The concentrations of Al, Fe, Mn, Ba, Cd, Cu, Cr, Ni, Pb, V, Hg, and Zn were obtained from acid digestion and quantified using flame atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES). The metals showed a similar order of concentration: Al > Fe > Ba > Mn > V > Ni > Pb > Cr > Zn > Cu, in both the Ceará; and Rio Grande do Norte shelf regions but different in the Espírito Santo shelf (Fe > Al > Mn > Ba > Zn > V > Cr > Ni > Pb > Cu. The concentrations of Hg and Cd were below the detection limit in all areas. A multivariate analysis revealed that the metals of siliciclastic origin on the continental shelf of Ceará are carried by Al. In addition, a large portion of metal deposits is connected to the iron and manganese oxides on the continental margin of Rio Grande do Norte. The metals from the continental supply on the coast of Espírito Santo (Cu, Ni, Ba, and Mn) are associated with Al; whereas Cr, Pb, V, and Zn are associated with iron in this southern area. Geochemical evaluations are needed to distinguish the origin and mineralogical differences of marine sediments within the regions. Scanning electron microscopy/energy dispersive spectrometry (SEM/EDS) applied to the sediments from the coast of Ceará showed the morphological diversity of sediment grains: biological fragments, multifaceted particles, aggregates, and crystals occurred in the three regions analyzed. Among these grains, calcite, Mg-calcite, and aragonite were predominant in the northeastern sector, whereas silicates and other minerals were predominant the southeastern sector. Mg, K, Ti, and Zr as well as the

    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 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.

    Full Text Available Different Corporate Governance mechanisms have been suggested to minimize agency problems between managers and shareholders, and between controlling and minority shareholders. The aim of this study is to analyze the corporate governance mechanisms result in greater efficiency for Brazilian stock companies in the electricity sector, in 2007-2009. The hypothesis to be verified is that the lower the voting concentration   and the dependence of the council, and the greater the cash flow concentration, the greater the performance of the company will be. The analyzed sample involved thirty-three companies, fourteen being classified into one of the levels of CG (Level 1, Level 2 or New Market and the remainder being members of the traditional market. To measure the efficiency of the companies, the non-parametric DEA (Data Envelopment Analysis method was used, and to relate the efficiency with the governance variables, we adopted regression analysis of panel data. The results demonstrated that the use of CG mechanisms positively influences business efficiency, but not in the expected magnitude. It was found that the cash flow concentration is positively related to the efficiency of firms, supporting the governance literature. For future work, the use of other input and output variables is suggested.

    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)

    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.

    Full Text Available This article considers the assessment of investment projects with the usage of characteristic examples, taken from gas and oil sectors of the industries, which are of crucial importance for the economies of Ukraine and Russia. These branches of industry are characterized by insufficient definition and complicacy, which necessitates the financial analysis of these sectors in Ukraine and Russia, especially if it is made for the assessment of the investment projects. In the long-term investment budget planning of the company the financial analysis is carried out to determine the investment possibilities, the value of which for the company is more than the money necessary for the ensurance of such possibilities. A few proposed methods can help specialist-analysts to take right decisions concerning investments.

  13. Life cycle greenhouse gas emission assessment of major petroleum oil products for transport and household sectors in India

    International Nuclear Information System (INIS)

    Energy security concerns due to high oil import dependence and climate change concerns due to related greenhouse gas emissions are important policy discussions in India. Could life cycle assessment (LCA) of petroleum oil products provide inputs to crude oil sourcing and domestic oil pricing policies to address the two concerns? This paper presents a baseline study on LCA of petroleum products in India from Well to Storage depending on the oil source, type of refinery, product and the selected destinations. The LCA based GHG emissions are found to be higher by 4–12 per cent than GHG emissions from direct fuel consumption alone for LPG, 7–10 per cent for Gasoline, 3–9 per cent for Diesel and 4–10 per cent for Kerosene based on various supply chain routes supplying oil to six largest cities in India. Overall the energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6–8 per cent, respectively. The paper proposes imposing a relative carbon cess for various oil products in different Indian cities. States could accommodate this additional carbon cess by reducing their respective state taxes without increasing the final delivery price to the consumers. - Highlights: ► LCA emissions are found to be higher by 4–12 per cent than direct fuel consumption emissions. ► Energy used in oil exploration, refinery and transportation in the LCA have a share of 72–77 per cent, 11–15 per cent and 6 8 per cent, respectively. ► Corresponding GHG emission shares are 60–66 per cent, 23–27 per cent and 5–8 per cent, respectively. ► The source of crude oil matters. E and P energy consumption is found highest for African countries. ► Differential carbon cess could be imposed without changing final delivery price to consumers

    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)

  15. Long-term oil strategy - creating an appropriate fiscal regime in OPEC countries to keep the upstream sector competitive

    International Nuclear Information System (INIS)

    The focus of this paper is to examine the factors that governed the upstream activities in OPEC countries during three distinct periods, namely: 1950 to 1973, 1974 to 1985 and 1986 to the present. Particular emphasis will be placed on the fiscal and legal instruments adopted by a number of OPEC countries in attracting oil companies to their respective countries, so as to maintain the momentum of oil exploration and production which is commensurate with their huge hydrocarbon reserves and also be in consonance with their pace of economic development while continuing to exercise their sovereign rights. The first part of the paper reviews the concepts governing the strategic behaviour of oil companies and oil-producing countries. Part two is devoted to the evolution of fiscal regimes in OPEC countries showing how the behaviour of OPEC Member Countries and oil companies illustrates the concepts in part one. How the dynamics of the oil market influence the upstream planning in OPEC Member Countries is examined in part three of the paper. Part four looks at the new cooperation and strategic alliances that are evolving between some OPEC countries and a number of oil companies to ensure that OPEC retains a leadership position which is commensurate with its Members' hydrocarbon resources. Conclusions are drawn in part five. (author)

  16. 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.

  17. Energy policy, social exclusion and sustainable development: The biofuels and oil and gas cases in Brazil

    2010-09-15

    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.

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.

    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 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)

    Fossil fuel are used in power generation in oil and gas producing countries due to the resource availability. However, the growing electricity demand, the potential exports revenues associated to hydrocarbons as well as the environmental policies have to be taken into account for the definition of the electricity generation mix. Thus, the development of the power generation capacities according to the resource availability and the economic factors (demand and costs) is investigated through a modeling approach. Over the past ten years, Egypt has become an important gas producer and a strategic gas supplier for Europe. Moreover, natural gas represents around eighty percent of the Egyptian power sector mix. However, this extensive share of natural gas in power generation mix could not be sustainable in long-term due to the limited hydrocarbons' resources of Egypt. In this study, the current and future power generation situation of the country is analyzed through a dynamic linear programming model. Finally, a power generation strategy based on a gradual integration of nuclear and renewable is suggested. (authors)

    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

  12. 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.

    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 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.

    海底热油管道的悬空段由于没有周围泥沙的保温蓄热作用,停输之后管内温降比埋入海底泥沙中的管段快得多,故而其温降成为停输过程的关键.针对海底管线悬空段的热力特性,考虑原油凝固潜热对停输温降的影响,利用CFD软件,对其停输温降过程进行数值模拟.分析温降变化规律、不同海水温度对温降的影响,从而确定最佳停输时间,为海底热油管道制定再启动方案提供理论依据.%With no heat preservation effect of the sediment around the oil pipeline, temperature drop of the suspended sector of submarine oil pipeline is faster than the temperature of the sector embedded in the submarine sediment. So the temperature drop process becomes the key of stopping transportation. According to the thermal characteristics of the suspended sector of submarine oil pipeline, considering the impact of solidified the latent heat, temperature drop is simulated in submarine pipeline during shutdown with time by the CFD software. Change rule of temperature drop and the influence of the temperature of seawater are analyzed, which decide optimum time for shutdown and provides a theoretical guidance for safe submarine oil pipeline startup.

    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.

    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.

    Located in a region where over 40% of the world's oil and gas reserves lie and in a trend similar to that of its neighbors, Oman's economy has been reliant on crude oil export since the 1970's. Being aware of the dangers of this reliance along with the discovery of Natural Gas since the 1980s, the Omani government's policy of diversifying its economy has shifted its reliance on Oil to another fossil fuel, namely Natural Gas. Given that energy is the lifeline of Oman's economy, effective and efficient forward planning and policy development is essential for the country's current and future economic development. This presentation explores the current status of the energy sector in Oman from home production and import to eventual final uses. The presentation highlights the major issues with Oman's current energy policies and suggests various strategies that could be adopted by Oman for a more efficient and sustainable future.

    Full Text Available Orange seeds are a promising agroindustry-waste which can be implemented in the extraction and production of vegetable oil. The relationship between moisture content and water activity provides useful information for the processing and storage of this waste item. The aim of this study was to determine the mechanism of water sorption enthalpy-entropy of orange seeds (C. sinensis cv. Brazilians according to the moisture content. Therefore, desorption isotherms were determined at five different temperature (30, 40, 50, 60, and 70 ºC under a wide range of moisture content (0.005-0.057 kg kg-1 d.b. and water activity (0.02-0.756. Theoretical and empirical models were used for modeling the desorption isotherms. An analytical solution of the Clausius-Clapeyron equation was proposed to compute the isosteric heat of sorption, the differential entropy, and Gibbs free energy using the Oswin model when the effect of temperature on the hygroscopic equilibrium was considered.

    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.

    Naphthenic acids, C(n)H(2n+Z)O(2), are a complex mixture of alkyl-substituted acyclic and cycle-aliphatic carboxylic acids. The content of naphthenic acids and their derivatives in crude oils is very small, which hinders their extraction from matrixes of wide and varied composition. In this work, liquid-liquid extraction, followed by solid phase extraction with an ion exchange resin (Amberlyst A-27) and ultrasound desorption were used to isolate the acid fraction from heavy gas oil of Marlim petroleum (Campos, Rio de Janeiro, Brazil). The analysis was accomplished through gas chromatography coupled to mass spectrometry with electron impact ionization, after derivatization with N-methyl-N-(tert-butyldimethylsilyl)trifluoracetamide (MTBDMSTFA). The results indicate the presence of carboxylic acids belonging to families of alicyclic and naphthenic compounds which contain up to four rings in the molecule. PMID:16439253

    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)

    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.

    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.

Apesar disso, representam o estado da arte do conhecimento científico no assunto e esta pesquisa buscou identificar as contribuições da academia para a compreensão do regime de competência aplicado ao setor público no Brasil, por meio de uma revisão crítica dos estudos nacionais que tratam do tema. Foram selecionados os artigos que abordam o tema regime de competência no setor público, publicados de 2005-2012 em eventos e periódicos pontuados pela Capes, e que estão relacionados com contabilidade e/ou contabilidade pública. Os resultados indicam que não existe uma tendência definida de linhas de pesquisa e os achados de um estudo não costumam ser comparados com outros. As pesquisas não são levadas adiante, nem por outros autores, nem pelos próprios, e os autores não exploram lacunas deixadas por pesquisas anteriores, sejam elas nacionais ou estrangeiras.

    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)

To study this sector in more detail, the agricultural sector was broken down into two sectors: Familiar and Non-Familiar Agriculture Agribusiness. The goal...

  4. NORM in the Norwegian North Sea sector assessment, handling and management of LSA scale in the Norwegian oil and gas industry

    International Nuclear Information System (INIS)

    The origin of the NORM waste (LSA Scale) in the oil industry is the formation of sulphate and carbonate precipitates inside tubulars and other production equipment during oil production. The radioactivity content is caused by the co-precipitation of dissolved radium isotopes together with the macro quantities of barium and strontium. The waste problem occurs either when production equipment is taken ashore for cleaning or as a part of the final waste handling during decommissioning of oil installations. Especially production tubulars and oil-water separation equipment may contain amounts of LSA scale mixed with other materials. A survey of the NORM waste temporarily stored at the supply bases showed the following typical macro composition in decreasing order: sulphates, sand/clay, steel and corrosion products and oil components. The activity concentration of radium-226 varied between 10 Bq/g (the current exemption level) and 100 Bq/g, with an average of 23 Bq/g. The content of radium-228 and lead-210 was found to be typically 10 - 50 % of the radium-226 concentration. Since becoming aware of the problem in the early 1990's, the industry has incorporated the management of LSA Scale to be an integrated part of the HSE systems and procedures. LSA Scale is routinely identified offshore using field instruments and brought to shore for temporary storage. By today, a total of 250 tons of LSA Scale is temporarily stored at the oil industry supply bases along the Norwegian Coast awaiting a final storage solution. Guidelines for exemption levels and handling of LSA Scale from the Norwegian Radiation Protection Authority have been in place since 1997. These guidelines are currently under revision and new ones are expected to surface in 2005. (author)

    2015-10-01

    Full Text Available Brazilian diasporas overseas hasreceived little academic interest. Nevertheless, estimates suggest that around three million Brazilians currently live in other countries. The present study looks at a specific type of diaspora: small entrepreneurs from the Brazilian martial arts sector. The study adopts the case study method of research. The unit of analysis is comprised by the martial arts (capoeira and Brazilian jiu-jitsu. Data analysis used secondary and primary data from interviews. Cross-case analysis searched for similarities and differences in the internationalization processes of the two martial arts, using several analytical devices, such as chronologies, timelines, matrices, and pattern matching analysis. Evidences suggest that the concept of diasporic internationalization fits better capoeira than Brazilian jiu-jitsu. However, Brazilian jiu-jitsu shows an initial combination of diasporic and transnational characteristics, but more recently became fully transnational. Brazilian jiu-jitsu became a truly global business, formally organized and professionally managed. Capoeira, however, is still seen as non-commercial and as the preservation and practice of an ancient art. Such ethos, combined with the origin of its members in lower economic classes and their restricted access to capital turns internationalization into an often less profitable activity.

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)

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.

    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.

    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.

    Based on an analysis of comprehensive geological and geophysical research, a paleogeographical reconstruction of the region under study for the sandstone sedimentation is performed. The influence of local and regional tectonic movements on the relief-formation processes is examined. The influence of the morphostructures of the paleorelief and the nature of the sedimentation zones (the alluvial plain, emergent delta, the forward delta and the shallow-water bay regions) on the distribution of sandstone-aleurite lithofacies is demonstrated. An analysis is given of the geometric features of the seam-reservoirs in various zones, and models are given for the formation of gas and oil pools in the V-26 bed in the alluvial plain and emergent delta zone. An attempt is made to predict the pattern of these deposits in the deeply-submerged deposits of the foredelta.

    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.

The somehow chaotic Nigerian political terrain has thrown up several challenges, has thrown up issues, many issues that are subjects of debate. Since the emergence of the nascent democracy in 1999, this nation has witnessed several deregulations of oil downstream for which few Nigerians has benefited from it and majority of others are languishing in abject poverty. Starting from January 1, 2012, the Federal Government has stopped subsidizing Premium Motor Spirit and jacked up the price from N65/L to a minimum of N141. In some states, retailers dispense it at N160/L and there is already, widespread anger and resentment against the policy across the country. Therefore, any break in its chain of availability and price rationality, automatically follows a negative effect on the living standards of the citizens as their economic life shift downwards. An increase in fuel price essentially leads to increase in the cost of transportation of both persons and goods, and the final consumer bears the brunt through the purchasing of domestic food items or necessities. The increase in fuel will always lead to higher cost of production, a burden consumers will have to bear too. Landlords definitely increases house rents while workers agitates for higher wages. These have always provoked industrial unrest which has a negative impact on the economy. Without bias, a general increase in prices of goods and services (any time reduces the standard of living of Nigerian and more people will be dragged into the bracket of poverty line living below one dolor per day. These Nigerians have suffered prior to the democratic governance from 1999 to date. Democratic governance with the underlying emphasis on the alleviation of the citizenry to realize the ‘common good’ has not taken root in the popular consciousness of Nigerians.

A review of these exports was made together with a report of empirical research conducted with undergraduate university students in Holland to determine their evaluation and impressions of Brazilian footwear. Since the attitude of these consumers was largely negative, a recommendation was made that marketing professionals from these companies should endeavor to improve this poor attitude in order to increase the sales potential of Brazilian footwear.

  3. Globalization and the Brazilian balance accounts

    International Nuclear Information System (INIS)

    The globalization of the world economy calls for a country specialization with new structures for the product sectors and an increase in the competitiveness in areas of specialization. This process requires the amplification of markets and the adoption of technological innovations which increase the volume of economic trade, but also change trade relations. This process is made possible because of price stabilization and the stability and transparency of the exchange rate policy of various countries. In this work it is shown the opportunity to place nuclear energy as one of the sectors in which Brazil may have competitive advantages and enhance its external balance accounts, by the competitive substitution of imports by producing internally goods and services which technology is known by Brazilian firms and because of the increase in exports.

    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

    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.

    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)

    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.

    Petroleum is one of the main sources of energy in the world, occupying the first place of the Brazilian energy matrix. Therefore, technologies that involve the development and application of techniques capable of increasing the profitability of oil fields are important and require more thorough studies. In Brazil, self-sufficiency has been already reached in oil production, however it is necessary that improved oil recovery technologies be continually studied to maintain the current production or to increase it. Rio Grande do Norte (a Brazilian State) comprises many heavy oil reserves and the exploration activities in the Brazilian Basins of Campos, Santos and Espirito Santo have led to the discovery of large amounts of heavy oils. It is possible to increase heavy oil recovery in some of these reservoirs with the help of improved oil recovery processes, thus enhancing oil field productivity and profitability. Until recently, heavy oil reserves did not attract much interest. The lowest oil profitability, the low price of the oil barrel in the international market, the difficulties involved in its extraction and its refining, and the large amount of light and medium oils to be explored could not justify the investments. Maturity of light and medium oil fields and the significant increase in oil price placed that source of energy under a new perspective. In Brazil, the confirmed reserves constitute 2.9 billion barrels approximately, 26% of the total reserves, and the production should reach 450 thousand barrels daily or 25% of the total production predicted for 2010 (ANP, 'Agencia Nacional do Petroleo' - Brazilian Petroleum National Agency, 2006). To improve the capacity of drainage of the heavy oils and to increase its recovery, different thermal methods have been developed. Those more used involve steam in the process, because they are more efficient than other processes such as 'in situ' combustion or water injection. The steam is used with the

    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. 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 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.

  16. Exergy and environmental comparison of the end use of vehicle fuels: The Brazilian case

    International Nuclear Information System (INIS)

    Highlights: • Total and non-renewable exergy costs of Brazilian transportation service are evaluated. • Specific CO2 emissions of the Brazilian transportation service are determined. • Overall exergy efficiency of the end use of vehicle fuels in transportation sector is calculated. • A comparative extended analysis of the production and end use of transportation fuels is presented. - Abstract: In this work, a comparative exergy and environmental analysis of the vehicle fuel end use is presented. This analysis comprises petroleum and natural gas derivatives (including hydrogen), biofuels (ethanol and biodiesel), and their mixtures, besides of the electricity generated in the Brazilian electricity mix, intended to be used in plug in electric vehicles. The renewable and non-renewable unit exergy costs and CO2 emission cost are proposed as suitable indicators for assessing the renewable exergy consumption intensity and the environmental impact, and for quantifying the thermodynamic performance of the transportation sector. This allows ranking the energy conversion processes along the vehicle fuels production routes and their end use, so that the best options for the transportation sector can be determined and better energy policies may be issued. It is found that if a drastic CO2 emissions abatement of the sector is pursued, a more intensive utilization of ethanol in the Brazilian transportation sector mix is advisable. However, as the overall exergy conversion efficiency of the sugar cane industry is still very low, which increases the unit exergy cost of ethanol, better production and end use technologies are required. Nonetheless, with the current scenario of a predominantly renewable Brazilian electricity mix, based on more than 80% of renewable sources, this source consolidates as the most promising energy source to reduce the large amount of greenhouse gas emissions which transportation sector is responsible for

  2. Oil: Economics and politics

    International Nuclear Information System (INIS)

    A review is presented of the evolution of the international petroleum sector since 1973 with a special emphasis on the interdependence between the economic and political factors that influence it. Two issues are focused on: the effects of the nationalization of oil companies on the sharing of oil rents and on changes in the structure of the oil market; and the determination of oil prices. Definitions are presented of oil rents, and the reasons for OPEC nationalization of oil companies are explored. The effects of nationalization on market structures, expansion of free markets, and vertical integration are discussed. The existence of an oil price floor and the reasons for such a floor are examined. It is shown that nationalization induced an internalization of rents by the producing countries, leading to the emergence of a differential rent supported by the politics of the industrialized countries. Nationalization led to the breakup of systems of vertical and horizontal integration, with replacement by a new dual structure with OPEC controlling the upstream activities of the oil sector and oil companies controlling the downstream ones. Prices move between a floor price set by the costs of substitute deposits in the U.S., while the determination of ceiling levels by OPEC rests on successive fragile compromises. Overall oil is still a strategic product, despite the existence of spot markets, forward trading options, etc. 29 refs

    The Brazilian Constitution prohibits private investment in many activities of the Nuclear Industry. Right now, it is in progress a constitutional amendment that allows private companies to build and operate nuclear power plants of its own. This work rescues the historical reasons that led the Congress of 1988 to choose the State owned model for this sector. In addition, the arguments that are used to propose the present changes are repeated here. As indicated in INAC 2015 website, 'sustainable development is supported by three pillars: social, economic and environmental'. Thus, the organizational model to be adopted for the Nuclear Sector must meet these requirements. The official objectives of the energy sector, as set out in the law 9,478, are remembered. New objectives, better established, and also adapted to the electrical subsector, are shown. Besides the use of these objectives to choose the sources and related technologies for the electric generation, they also can be used as evaluation criteria to help in the decision process of the organizational model for the Nuclear Sector. Acting in this way, it is ensured that social, economic and environmental requirements are being attended. Finally, if the developed evaluation criteria are applied, the impacts of each organizational model can be analyzed and preliminary conclusion and recommendation can be made. (author)

    International Nuclear Information System (INIS)

    This article proposes a brief discussion of various assessments of Russian oil reserves, of the evolutions of Russian oil production (Russia is the second world producer after Saudi Arabia), of the distribution of Russian oil exports among various regions, and of the decrease of Russian oil consumption between 1992 and 2002. It describes the evolution of the actor system as the oil sector has been largely privatised since 1992, and indicates the main companies which should control the Russia market on a medium term. It also discusses the obstacles for the development of Production Sharing Agreements (PSA) between these companies. It addresses the issue of modernisation of the oil transport system as its status and its condition are often an obstacle to oil export for Russian companies. The article finally discusses the price issue, the relationship between Russia and other OPEC countries, and the need for huge investments

  7. Energy policy and regional inequalities in the Brazilian economy

    International Nuclear Information System (INIS)

    The objective of this paper is to evaluate the long-run regional impacts of the tariff policy of the Brazilian electric power sector. This sector has undergone a reform process that started in the 1990s. Since the beginning of the reform, two spatial trends of distribution of electric power tariffs have emerged among the Brazilian states, one of convergence and another of spatial divergence. These trends have been guided by the new electric power tariff policy and by the spatial features of the Brazilian economy, which is marked by a high degree of spatial concentration and hierarchical distribution of large markets. In addition, because of the presence of strong economies of scale, the recent electric power prices differentials might be caused by differentials in market size that provide better conditions for the achievement of economies of scale for electric power utility companies located in larger markets. Given the role of electric power as an important intermediate input in the production process and the interdependence between sectors, an Energy Interregional Computable General Equilibrium model was used to simulate the long-run regional impacts of electric power tariff policy in Brazil. The simulations showed that the heterogeneity of energy-intensity and the differentials of energy substitution drive the spatial impacts of changes in electric power prices. On the other hand, the recent trend of spatial dispersion of electric power prices might contribute to a decrease in the long-run economic growth and to an increase in the regional inequalities in Brazil. - Highlights: ► We model the regional impacts of tariff policy of the electric power sector in Brazil. ► High electric power tariffs increases in regions with higher electric-power-intensity. ► Heterogeneity of energy supply determines an unequal pattern of energy substitution. ► Low possibilities of energy substitution generate the most negative economic impacts

    Full Text Available The Bolsa Escola (‘school stipend’ and its successor the Bolsa Familia (‘family stipend’ schemes have formed a crucial and successful part of Brazil’s welfare program. Bolsa Escola provided aid to Brazil’s poorest families on the condition that their children attended school, and Bolsa Familia has extended this idea, giving aid on the condition that children both attend school and receive vaccinations. Bolsa Familia is currently the largest Conditional Cash Transfer Program (CCTP in the world, costing roughly 0.5% of Brazilian GDP and helping around 11.2 million families (around 44 million Brazilians, constituting roughly one fifth of the population. Multilateral institutions have praised the schemes, and they are setting a leading example to other developing nations. In 2005, Paul Wolfowitz (former president of the World Bank said, ‘Bolsa Familia has already become a highly praised model of effective social policy. Countries around the world are drawing lessons from Brazil’s experience and are trying to produce the same results for their own people’.

  9. Trust within Brazilian New Economy Organizations: an Empirical Investigation of Gender Effects Benchmarked on Brazilian Old Economy Organizations

    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.

    This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information. PMID:23099762

    This study investigates the latest research on the profile of the Brazilian prison population, its demography and current laws and regulations. It aims in the direction of ensuring the human right to health. Brazilian prison system is a complex universe in which state and federal criminal contexts keep more than 607,000 people in custody. This population is composed of 75% of young and black people, 67% poorly educated and 41% are pre-trial detainees, living in overcrowded prisons and architecturally vandalized, with population growth of around 575% in 24 years, making this environment a major focus of production of diseases. The prison becomes the object of differentiated intervention by public bodies linked to the executive and the judiciary - it is worth remarking that the data show the high level of inequalities and health vulnerabilities among the prison population, whose needs involve a set of cross-sector of transverse public policies actions towards penal execution.

    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.

    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.

    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)

    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.

    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.

    The effects of Sudden Stratospheric Warming on ionosphere have been investigated by several scientists, using different observational techniques and model simulations. However, the 2011-2012 minor event is one of those that are less studied. Since, the zonal westward wind is slowed without reversing to eastward, this SSW was consider as a minor event. The stratospheric temperature started increasing on December 26, 2011, reached its peak on January 18, 2012, and afterwards started decreasing slowly. In addition, there was moderate geomagnetic storm on January 22-25, 2012, after the SSW temperature peak. In the present study, the GPS-TEC measurements from a network of 72 receivers over the Brazilian region are considered. This network of 72 GPS-TEC locations lies between 5 N and 30 S (35 degrees) latitudes and 35 W and 65 W (30 degrees) longitudes. Further, two chains of GPS receivers are used to study the response of Equatorial Ionization Anomaly (EIA) changes in the Brazilian East and West sectors, as well as its day-to-day variability before and during the SSW2012. It was noted that the TEC is depleted to the order of 30% all over the Brazilian region, from equator to beyond the EIA regions and from East to West sectors. It is also noticed that the EIA strengths at East and West sectors were suppressed after the stratospheric temperature peak. However, the Brazilian West sector was found to be more disturbed compared to the East sector during this SSW event.

    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.

    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 This paper investigates the sources of structural change in the Brazilian economy in the 2000s. On that purpose, it uses the input-output structural decomposition analysis and introduces a method to correct the influence of prices on the time behavior of the technical coefficients, making them actually represent changes in the production structure. Results show that most of the growth differential between services and industry in that period was induced by the production structure: more precisely, by a lower intermediate consumption of domestic industrial inputs by the production chain of all economic sectors, concomitant with a higher intermediate consumption of services.

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.

  1. Eletronuclear's relationship with the Brazilian media: transparency and credibility

    International Nuclear Information System (INIS)

    In a capitalist economy the most valued assets are not money, shares or facilities, but credibility. Lack of money can ruin a company, but often it is reputation that delivers the final blow. It has become challenging to safeguard reputation in a world where Communication is increasingly connected and with such an intense and lightning fast flow of information. This is particularly true for the electricity sector - a commodity so prevalent in everyday modern life, but, whose business dealings, are hardly known by the general public. When it comes to nuclear energy, the challenge of establishing an effective Communication with transparency and credibility touches on even more complex elements. The topic of this paper is the scenario through which the Communication process, along with its characteristics and approaches, unfolds between the nuclear sector and the Brazilian media. (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

    Full Text Available Sectoral Shifts and Cyclical Fluctuations This paper studies a two sector real business cycle model in which the sectors experience different trend rates of growth and labor mobility is costly. Predictions are derived concerning the correlation between sectoral reallocation of workers and the cycle. This correlation may be positive or negative depending upon whether the growing sector displays larger or smaller fluctuations than the shrinking sector. The post- World War II period has witnessed two major patterns of sectoral change in industrialized countries: movement out of agriculture and movement out of the industrial sector. The model's basic prediction is shown to be consistent with the observed pattern of reallocation.

  6. The challenge of energy poverty: Brazilian case study

    International Nuclear Information System (INIS)

    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. -Research highlights: → The access to electricity led to a marked change in the reality of the researched population. → Energy poverty and energy inequality were reduced significantly. → The strategy of combating energy poverty through programs of rural electrification is efficient.

    Directory of Open Access Journals (Sweden)

    Victor Manoel Cunha de Almeida

    2015-12-01

    Full Text Available According to Brazilian Franchising Association, the number of Brazilian franchises has grown 300% in the last ten years, but only 3% of Brazilian franchises operate in foreign markets, so the opportunity to internationalization is strong. Aiming to get a better understanding of possible distinctive features of Brazilian retail internationalization, this paper explores the determinants of franchising as the choice of internationalization entry mode by Brazilian’s firms in the fashion apparel sector. The multiple-case study was the approach used. The study resulted in eleven research propositions. Results show that government or trade organizations support, geographic distance, political and economic risk may not be determinant to internationalization. However cultural proximity and relationship with local partners can be determinant to internationalization. Moreover, brands that cater to a very specific segment and that their value proposition is closely linked to intangible factors may face problems in expanding to culturally distant international environments.

  11. Brazilian Alcohol Program (Proalcool): economic re-evaluation and demand adjustments

    International Nuclear Information System (INIS)

    The aim of this paper is to discuss the economic impact on the Brazilian National Alcohol Programme caused by changes in the energy scenery, in view of recent oil price fall in the international market, and evaluate the necessary adjustments of the Programme according to the new Brazilian economic reality. The economic analysis concludes that the alcohol production, considering current production capacity and its investments, could be economically feasible at international oil prices near US$ 30.00. Excluding investments, its feasibility would be between US$ 18.00 and US$ 20.00 per equivalent oil barrel. Based on these conclusions, proposals for adjusting the PROALCOOL are discussed, including alternative pricing, fiscal and credit policies to control the alcohol-fuel demand. (author)

  12. The Brazilian experience with alcohol fuel: microeconomic and environmental issues

    International Nuclear Information System (INIS)

    Producers and consumers in Brazil are not longer regarding alcohol (ethanol) as a valuable fuel choice. Although the falling of oil prices has contributed to this situation, the lack of concern on microeconomic behaviour has also played an important role. Furthermore, environmental gains derived from the use of a mixture of alcohol and gasoline have been forgotten when alcohol fuel is evaluated. From the Brazilian experience some fruitful lessons can be learnt, to support research efforts for renewable energy programmes in Europe and the U.S.A. (author)

    International Nuclear Information System (INIS)

    Oil and Power: Iraq at the Crossroads is the first analysis which specifically addresses the oil sector in Iraq. It provides a detailed account of the present Iraqi oil infrastructure and assesses the risks and opportunities facing those who seek to invest in its redevelopment. The report examines the implications for the world oil markets of Iraq's ambitious plans to expand production capacity to 6m barrels per day -almost twice its pre-war peak. It explains in clear, authoritative terms the profound problems confronting Iraq's oil sector and the prospects for rebuilding it. It analyses expertly and in detail the current regime's chances of survival and examines the alternative contenders for power -and their likely attitudes towards co-operation with foreign oil interests. The report examines and explains: Iraq's oil infrastructure, from fields under exploration to nominal administrative structure; the effect on oil prices of Iraq's eventual re-entry into the oil market; the facilities in need of repair and where the shortage of spares and human expertise are; the unofficial decision-making structure in the oil sector; the short- and medium-term impact of economic disintegration on oil development policy; the effects of UN sanctions and the motives of those supporting or opposing sanctions; the likely impact of prevailing economic constraints on Iraqi oil and the historical role of commissions in Iraqi oil contracts; the political impact of General Hussein Kamal Hassan's defection and the Kurdish and Shi'ite threats to Iraqi national unity.

    In this work, we study the behavior of Brazilian politicians and political parties with the help of clustering algorithms for signed social networks. For this purpose, we extract and analyze a collection of signed networks representing voting sessions of the lower house of Brazilian National Congress. We process all available voting data for the period between 2011 and 2016, by considering voting similarities between members of the Congress to define weighted signed links. The solutions obtained by solving Correlation Clustering (CC) problems are the basis for investigating deputies voting networks as well as questions about loyalty, leadership, coalitions, political crisis, and social phenomena such as mediation and polarization.

    Full Text Available Abstract: The concentration and the chemical composition of the essential oils obtained from different samples of Cymbopogon citratus were evaluated. Among the 12 samples investigated (11 dried leaf samples and fresh plant leaves, seven presented essential oil concentrations within the threshold established by the Brazilian legislation. The moisture content was also determined and the majority of the samples presented humidity contents near 12%. The GC and GC/MS analyses of the essential oils led to identification of 22 compounds, with neral and geranial as the two major components. The total percentage of these two compounds varied within the investigated sample oils from 40.7% to 75.4%. In addition, a considerable variation in the chemical composition of the analyzed samples was observed. The process of grinding the leaves significantly decreased (by up to 68% the essential oil content, as well as the percentage of myrcene in the oils.

  17. Solidarity liability of the cooperatives part of the Unimed Group – a Brazilian private healthcare insurance

    Directory of Open Access Journals (Sweden)

    SCHEFFER, Mario

    2016-06-01

    Full Text Available Unimed medical cooperatives – a Brazilian private health insurance- are a very expressive group in the Brazilian supplementary healthcare market, as they bring together the largest number of beneficiaries and present the highest turnover in the sector. In light of the decision of the Brazilian Superior Court of Justice (STJ recognizing the solidarity liability related to obligations of any company belonging to the group Unimed, this article analyzes arguments and implications of this judgment. The transparency obligation stems from the basic consumer’s right to receive clear and adequate information on the marketed services and products. As for the good faith, it is linked to the loyalty that the parties must maintain at every stage of the contract, in respect to the expectations created. This article concludes that the STJ’s position, related to the responsibility of all companies of the Unimed Group, is a logical and necessary outcome.

    Full Text Available The study analyzed The Brazilian Policy for Reduction of Morbidity and Mortality from Accidents and Violence, in the socio-political perspective. We used as a base the chapter “Violence: a global public health problem” from the World Report on Violence and Health. The analysis revealed convergent and divergent elements of the Brazilian Policy in comparison with the international perspectives. We verified that the Brazilian Policy tried to converge to the international policies, however: it emphasizes the health promotion actions, but are limited to the context and behavior of individuals and individual communities; the performance of health professionals is expected without providing more structural investments, as the improvement in work conditions, the increase of financial and material resources; there are few clear definitions of the government and economical sector responsibilities.

  1. Heat and power demands in babassu palm oil extraction industry in Brazil

    International Nuclear Information System (INIS)

    The objective of this paper is to analyze the energy use profile of the babassu (Orbignya ssp-Palmae) oil extraction industry in Brazil in order to establish the basis for a cogeneration study of this important part of the Brazilian Northeast region economy, which is still ignored by energetic biomass studies. The work used information from new equipment suppliers that was analyzed against field information from operating units. The data was used to establish a basis for the thermal and mechanical energy consumption for the two main basic unit profiles for the sector: a simple one with just oil extraction and the other, more vertically integrated with other secondary by-products. For the energetic demand taken from the only oil extraction unit profile study, the minimum pressure for the steam process was estimated at 1.4MPa, electric demand at 5.79kW/ton of processed kernel and heat consumption at 2071MJ/ton of processed kernel (829kg steam/ton of processed kernel). For the vertically integrated unit profile, the following values were found: minimum pressure for the steam process 1.4MPa, electric demand 6.22kW/ton of processed kernel and heat consumption 21,503MJ/ton of processed kernel (7600kg steam/ton of processed kernel)

    Full Text Available Due to the necessity of establishing animal welfare standards for the Brazilian dairy sector in harmony to the new consumer’s requirements and legislation, it was drawn up the project Welfare Quality (WQ - Brazil, based on the proposed project Welfare Quality ® European Union for dairy cattle. The assessments of animal welfare were performed in seven dairy farms at São Paulo/Brazil. They were selected in order to represent the main types of dairy farms found in Brazil. To carry out the project, it was used the evaluation protocol of welfare in Dairy Cattle Welfare Quality ® Assessment Protocol for Cattle, which is based on the principles of Good Feeding, Proper Installation, Good Health and Appropriate Behavior. The protocol defines four possible categories for the assessed dairy farms: Not classified, Acceptable, Enhanced or Excellent. Only one farm received category “Acceptable”, while the others received category “Enhanced”. A highlight is the unsatisfactory score for the principle “Appropriate Behavior” received by four farms. Possible reasons are inappropriate animals handling, assessor subjectivity and/or protocol’s subjectivity. To this final point, some emotion standards are vague and do not describe how animals should behave for each type of situation during evaluation. Finally, it can be concluded that the European protocol for the Evaluation of Welfare in Dairy Cattle Welfare Quality ® may be used in Brazilian dairy farms provided there is previous assessor training and adaptation of some points to be feasible to Brazilian dairy sector.

  6. The oil and oil services industry international context 2008

    International Nuclear Information System (INIS)

    Oil companies rarely do their own major work within the framework of their investments or in the operation of their facilities. They most often act as project coordinators, thereby opening up a vast market for equipment, services and engineering, involving many companies of widely-varying sizes, which constitute the oil services industry. This document provides a panorama of the international oil context in three distinct parts, for 2007, for the first three quarters of 2008, and aspects of trends for 2009. - The first part is devoted to a rapid description of the oil context and the economic environment in which it is evolving. - The second part examines the evolution of world investment in exploration-production (E and P) activities, distinguishing the investments made by oil and oil product/service companies throughout the E and P chain from the more targeted ones of three specific sectors: seismic, drilling and the construction of offshore production equipment. These markets are observed exclusively for oil product/service companies. - The last part is devoted to investments in the refining sector, focusing on the changes in the fundamentals, particularly the equilibrium between refining capacities and medium- term oil demand. This latter analysis involves both oil and oil product/service companies. (authors)

  7. The energy sector abroad. Part 5. Norwegian energy sector large exporter of natural gas

    International Nuclear Information System (INIS)

    Some facts about the Norwegian natural gas and oil industry are presented. In 1995 the industries took 12.5% of GNP and no less than 47.6% of export revenues. The use of natural gas in Norway is low. In 1996 Norway exported 37.9 billion m3 of natural gas. It is planned to double that volume within the next 10 years. Therefore, a strategic alliance between two major foreign competitors (Gasunie in the Netherlands and Gazprom in the Russian Federation) was not met with enthusiasm. The three most important companies in the Norwegian oil and gas industry are Statoil, Norsk Hydro, and Saga Petroleum. Overall turnover of the sector in 1994 was 40.6 billion Dutch guilders. Some 17,500 people are directly employed by the sector. 5 ills., 5 tabs

    International Nuclear Information System (INIS)

    As energy demand and prices continue to grow, oil shale might help mitigate the energy crisis—it can widely be found all over the world but so far has not been widely used. Estonia is unique in the world for producing a large majority of energy out of oil shale and has been set as an example in numerous papers covering oil shale deposits, technology etc. This paper is the first to analyse oil shale energy related workforce and provides scenario forecasts of the labour demand for the Estonian energy sector in 2010–2020. The contribution of the paper is twofold. First, the paper provides a valuable insight into oil shale energy related workforce, enabling to take into consideration the educational needs in countries where oil shale industry might be set up. Second, methodology-wise, the paper relates labour demand and supply to different scenarios of energy production capacities. The results illustrate problems related to aging of the workforce in energy production. If the existing trends continue in educational attainment in Estonia, there will be a serious shortage of high-skilled engineering and manufacturing specialists. Our method provides a simple yet reliable enough way to check for such problems early enough. - Highlights: ► This paper analyses oil shale energy related workforce and provides scenario forecasts. ► This is the first study to investigate the workforce related to oil shale energy production. ► The main workforce-related problem in the sector is ageing of the workforce. ► Workers immigrating to the sector during the Soviet times are at the retirement age. ► There will be a serious shortage of engineers for energy sector in the near future.

    1996-12-01

    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)

    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.

    The post-rift sedimentary strata of the Brazilian coastal basins are made of two main sequences: the evaporite and carbonatic Albian-Aptian sequence, and the open-marine Late Albian to Recent sequence, both related to the opening of the South Atlantic Ocean. More than 40 billion barrels of oil-equivalent in place has been found in these sequences, mostly in siliciclastic reservoirs above and below the Aptian salt beds. The productive basins are Campos, Espirito Santo, Sergipe-Alagoas, Potiguar, Ceara, and Santos, but the first one is responsible for more than 60% of the original oil in place discovered in these basins. The hydrocarbon origin, migration, and accumulation models in these sequences are discussed and exemplified by some giant oil fields of Campos and Sergipe-Alagoas basins, where oil is trapped in Aptian conglomerates, Albian carbonates, and Upper Cretaceous to Tertiary turbidite sandstones. The cumulative production in these sequences reaches 958.6 million barrels and the proved exploitable reserve amounts reach 2.7 billion barrels of oil-equivalent. Petrobras' exploratory forecast indicates that the post-rift sequences are the most prolific ones in the Brazilian marginal basins. The oil-equivalent that is expected to be discovered, particularly in deep water areas, where giant oil fields (as the Marlim field) have been found, exceeds the amount that has been discovered until now.

  1. Yukon energy sector assessment 2003 : final report

    International Nuclear Information System (INIS)

    A study was conducted to better understand energy issues in the Yukon. The study was based on the Yukon Energy Matrix which looks at the Yukon energy sector from the perspective of the capacity to supply various forms of energy, the markets for energy in the Yukon, and energy users. The sources of non-renewable energy in the Yukon range from natural gas, coal and oil. Renewable energy sources are also diverse and include water, biomass, wind, solar and geothermal. The main sources of electricity production in the Yukon are oil, water and wind. The link between energy and climate change has gained much attention in recent years, resulting in effective measures to conserve energy and increase energy efficiency. Coal, gas and oil are imported into the Yukon from markets in southern Alaska despite the fact that Yukon has its own vast quantities of these fossil-based forms of energy. As a result, the price of fossil-fuels consumed in the Yukon is determined in national and international markets. The absence of non-renewable energy production in the Yukon is also reflected in the lack of pipeline and rail infrastructure in the territory. The Yukon's electricity transmission grid is also very fragmented. For the purpose of this paper, energy use was categorized into the residential, commercial, industrial and transportation sectors. 19 refs., 8 tabs., 12 figs

  3. Attribution of CO2 emissions from Brazilian deforestation to domestic and international drivers

    Efforts to address extensive deforestation to reduce climate change and save primary forests are taking place on a global scale. Whilst several studies have estimated the emissions occurring from deforestation in large rainforests, few studies have investigated the domestic and international drivers sustaining and increasing the deforestation rates. Brazil, having the largest rainforest in the world and one of the highest deforestation rates, is also currently one of the world's largest exporters of soybeans and beef. In this case study we establish the link between Brazilian deforestation and cattle and soybean production, and further attribute emissions to countries and economic sectors through export and import of Brazilian commodities. The emissions from deforestation can therefore be allocated to the countries and sectors consuming goods and services produced on deforested land in Brazil. A land-use change model and deforestation data is coupled with a carbon cycle model to create yearly emission estimates and different emission allocation schemes, depending on emission amortizations and discounting functions for past deforestation. We use an economic multi-regional input-output model (with 112 regions and 57 sectors) to distribute these emissions along agricultural trade routes, through domestic and international consumption in 2004. With our implementation we find that around 80 % of emissions from deforested land is due to cattle grazing, while agricultural transition effects suggests soy beans are responsible for about 20 % of the emissions occurring in 2004. Nearly tree quarters of the soy beans are consumed outside Brazil, of which China, Germany and France are the biggest consumers. Soy beans are consumed by a variety of sectors in the food industry. Brazil exports about 30 % of the cattle it produces, where Russia, USA and Germany are among the largest consumers. Cattle consumption mainly occurs in the meat sectors. In this study we estimate the CO2

    This paper first reviews proposals for the design of sectoral and related market mechanisms currently debated, both in the UNFCCC negotiations, and in different domestic legislative contexts. Secondly, it addresses the possible principles and technical requirements that Parties may wish to consider as the foundations for further elaboration of the mechanisms. The third issue explored herein is domestic implementation of sectoral market mechanisms by host countries, incentives to move to new market mechanisms, as well as how the transition between current and future mechanisms could be managed.

  5. Oil: economic and political factors

    International Nuclear Information System (INIS)

    This article deals with the evolution of the international petroleum sector since 1973 with a special view to interdependence between the economic and political factors that influence it. Two issues are focused upon: (1) the effects of the nationalization of oil companies on the sharing of oil rents and on changes in the structure of the oil market; and (2) the determination of oil prices. The latter involves a discussion of, on the one hand, the political and economic behaviour of the United States and Saudi Arabia and, on the other, the combination of cooperation and conflict that has tended to characterize relations among OPEC countries.

    The ever-increasing energy demand of the residential sector has required the adoption of tighter energy standards, aiming for high energy efficiency in dwellings. In Brazil, 24 million new residential buildings are planned to be delivered by 2022 through social housing programs, which could greatly impact on the country’s energy consumption. In an attempt to minimize this impact, the Brazilian Labelling Scheme for Residential Buildings (RTQ-R label) was launched in 2010 as a voluntary standar...

  10. A very competitive oil

    International Nuclear Information System (INIS)

    Drop in oil barrel prices results in 8 to 10 billions in savings for French companies, i.e. as much as the tax credit for competitiveness and employment. This article analyses how the different sectors take benefit of this saving due to lower oil prices. It outlines that this decrease has been very profitable for the refining sector which exhibited historic margins. As far as the chemistry sector is concerned, costs are reduced but profits are less important as this decrease compensates the decrease of the euro with respect to the dollar. The plastic industry does not take profit as it comes at the end of value chain where other actors already took their benefits. Therefore, there is no profit in agriculture as far as plastic products and fertilizers are concerned. On the opposite, the decrease of marine fuel has been profitable to the fishing sector as well as to the sea transport sector. As far as road transport is concerned the fuel price decrease is reflected in resale prices, and the oil price decrease had therefore no impact, or only for few days. It's not the case for air transport where companies took benefit of this decrease. In this respect, a second article outlines that airline companies have learned lessons from previous oil price counter-shock to adapt their strategies. The last article addresses the general situation of industry which exhibits a better financial health, could be boosted by a recovery of consumption. But growth is still to be confirmed by investments. A brief article notices that the profit is less important at the world level, i.e. more important in Europe than in Asia and even more than in Africa

  13. Hedging with futures contracts in the Brazilian soybean complex: BM&F vs. CBOT

    Directory of Open Access Journals (Sweden)

    Andréia Regina O. da Silva

    2003-06-01

    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.

  14. Investimento direto estrangeiro e o desempenho das exportações brasileiras Foreign direct investment and the performance of Brazilian exports

    Full Text Available Brazil, in the 1990s, assumed a remarkable position as a host of foreign direct investment. It is worth mentioning that the service sector received the highest proportion of foreign investment. This market seeking strategy was responsible for the growth of the Brazilian imports. The results are confirmed by the performance of foreign enterprises into different groups of activities. Those enterprises with majority of foreign capital have increased their imports the most from 1995 to 2000. Therefore, during the 1995-2000 period, this study does not support the view that foreign investment has directly improved the performance of the Brazilian exporting sector.
