    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)

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

    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.

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

    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.

    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.

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

    Full Text Available 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.

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

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

    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.

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

    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. Internationalization. Strategy.

    A very intense geomagnetic storm (superstorm) began with storm sudden commencement (SSC) at 08:03 UT on 20 November 2003, as a result of the coronal mass ejection (CME) by sunspot 484 hurled into space on 18 November 2003. The geomagnetic storm attained |Dst|max=472 nT at 20:00 UT (20 November). In this paper we present the simultaneous ionospheric sounding observations, using the Canadian Advanced Digital Ionosondes (CADIs), carried out from Palmas (PAL; 10.2° S, 48.2° W; dip latitude 5.5° S; a near equatorial station) and São José dos Campos (SJC; 23.2° S, 45.9° W; dip latitude 17.6° S; station located under the crest of equatorial ionospheric anomaly), Brazil. In addition, total electron content (TEC) measurements from several GPS receiving stations in the Brazilian sector during this storm are presented. The simultaneous ionospheric sounding observations carried out at SJC and PAL, and TEC observations on 3 consecutive days viz., 19 November (quiet), 20 November (disturbed) and 21 November (recovery phase) are presented. Salient features from the ionospheric observations in the Brazilian sector during the superstorm are discussed. The difference in the observed ionospheric response at the two stations (PAL and SJC) is considerable. This is not surprising given that PAL is close to the magnetic equator and SJC is near the crest of the equatorial ionospheric anomaly (EIA). It should be pointed out that soon after the SSC (about 4 h later), the F-region critical frequency (foF2), the F-region peak height (hpF2), and variations of virtual heights at different frequencies (iso-frequency plots) all show wavelike oscillations of the F-region during daytime at both the ionospheric sounding stations. Unusual rapid uplifting of F-region at PAL was observed during both the main and recovery phases of the storm.

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

    Based on the daily price data of spot prices of West Texas Intermediate (WTI) crude oil and ten CSI300 sector indices in China, we apply multifractal detrended cross-correlation analysis (MF-DCCA) method to investigate the cross-correlations between crude oil and Chinese sector stock markets. We find that the strength of multifractality between WTI crude oil and energy sector stock market is the highest, followed by the strength of multifractality between WTI crude oil and financial sector market, which reflects a close connection between energy and financial market. Then we do vector autoregression (VAR) analysis to capture the interdependencies among the multiple time series. By comparing the strength of multifractality for original data and residual errors of VAR model, we get a conclusion that vector auto-regression (VAR) model could not be used to describe the dynamics of the cross-correlations between WTI crude oil and the ten sector stock markets.

    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.

    In this paper, we have investigated the responses of the ionospheric F region at equatorial and low latitude regions in the Brazilian sector during the super geomagnetic storm on 15-16 May 2005. The geomagnetic storm reached a minimum Dst of -263 nT at 0900 UT on 15 May. In this paper, we present vertical total electron content (vTEC) and phase fluctuations (in TECU/min) from Global Positioning System (GPS) observations obtained at Belém (BELE), Brasília (BRAZ), Presidente Prudente (UEPP), and Porto Alegre (POAL), Brazil, during the period 14-17 May 2005. Also, we present ionospheric parameters h'F, hpF2, and foF2, using the Canadian Advanced Digital Ionosonde (CADI) obtained at Palmas (PAL) and São José dos Campos (SJC), Brazil, for the same period. The super geomagnetic storm has fast decrease in the Dst index soon after SSC at 0239 UT on 15 May. It is a good possibility of prompt penetration of electric field of magnetospheric origin resulting in uplifting of the F region. The vTEC observations show a trough at BELE and a crest above UEPP, soon after SSC, indicating strengthening of nighttime equatorial anomaly. During the daytime on 15 and 16 May, in the recovery phase, the variations in foF2 at SJC and the vTEC observations, particularly at BRAZ, UEPP, and POAL, show large positive ionospheric storm. There is ESF on the all nights at PAL, in the post-midnight (UT) sector, and phase fluctuations only on the night of 14-15 May at BRAZ, after the SSC. No phase fluctuations are observed at the equatorial station BELE and low latitude stations (BRAZ, UEPP, and POAL) at all other times. This indicates that the plasma bubbles are generated and confined on this magnetically disturbed night only up to the low magnetic latitude and drifted possibly to west.

    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 This study on the factors affecting the adoption of supply chain management (SCM practices develops four hypotheses based on a literature review, and tests them using survey data of Brazilian electro-electronic firms. The results reveal the big picture of the SCM practices in the sector and suggest that contextual factors such as size, position and bargaining power affect the adoption of SCM practices, which are also more customer oriented. Sector characteristics are very important in analysing SCM practices. Contrary to the findings of literature, the relationship between competitive priorities and SCM practices was not supported statistically.

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

    We present some evidence of the major Sudden Stratospheric Warming (SSW) events, which occurred during low solar activity of years 2008, 2009 and medium solar activity of 2013, as observed on Total Electron Content (TEC), MLT wind, and vertical plasma drift parameter. The Total Electron Content (TEC) was collected from the International Global Positioning System (IGS) and from the Brazilian Network of Continuous Monitoring (RBMC) stations. Daytime E´B vertical drift were derived from the magnetometers located at the equatorial station Alta Floresta (9.9ºS, 55.9ºW, dip lat: 1.96º) and an off equatorial station Cuiaba (15.3ºS, 56.0ºW, dip lat: 7.10º), both in the Brazilian sector, while the mesosphere and lower thermosphere (MLT) meridional and zonal wind components were measured by the Meteor Radar located at the southern mid-latitude Santa Maria (29.4ºS, 53.3ºW, dip lat: 17.8º) station. During the SSW events the GPS-TEC data exhibit a distinctive daytime and nighttime anomaly pattern with a suppression of Equatorial Ionization Anomaly (EIA) in the afternoon and enhancement of EIA during the morning hours. TEC was also characterized by semidiurnal and large amplitude, which lasted for several days mainly in 2008 and 2009 events. For 2013 event, we identify the anomalous variation in E´B drift based on later local time migration of peak value with SSW days. A novel feature of this study is the identification of the similar migration pattern in the TEC anomaly, in spite that the simultaneous solar-flux increases during the SSW event of 2013. Other novel features are the amplification of the 13-16 day periods in the TEC anomaly during the SSW days, and simultaneous amplification of these periods in the meridional and zonal wind components in the MLT region, as far as 30o S. These aspects reveal the presence of coupled atmosphere-ionosphere dynamics during the SSW event and the amplification of the lunar and/or solar tidal component, a characteristic which is

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

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

    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.

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

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

    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. Até o ano de 1997, o mercado brasileiro era caracterizado pelo monopólio estatal da Petrobrás, a qual permaneceu, até 2001, como a única empresa autorizada a importar derivados de petróleo. Com vários agentes operando no mercado, o governo deixou de fixar os preços para a Petrobrás, que passou a determinar os preços baseada na competição com outros agentes. Neste cenário, surgem algumas questões relativas aos níveis de preços a serem oferecidos no mercado e relativas à capacidade das refinarias nacionais de competir com produtos importados. Para responder a estas e outras questões, um novo modelo de equilíbrio espacial de preços para um mercado oligopolizado foi

    For the Brazilian electric sector built up from the sixties, the plan was always the viability of the private accumulation, materializing in a implicit privatization based on the purchase decision and sectorial investments. From the nineties on this logic became more deep, aiming the total handing over to the private interests, the control of the concessionaires through the share control sales and the creation of regulatory and legal frame work to guarantee this objective. This paper discusses the challenge and problems of the Brazilian electric sector.

    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.

    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.

    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.

    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.

    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.

    Full Text Available The significant share of oil sector of the Azerbaijan export portfolio necessitates promotion of non-oil exports. This study analyzes weather the commodities which contain the main share (more than 70% in non-oil export are traditional or non-traditional areas, using the so-called Commodity-specific cumulative export experience function, for the 1995-2015 time frame. Then, the impact of traditional and non-traditional exports on non-oil GDP investigated employing econometric model. The results of the study based on 16 non-oil commodities show that cotton, tobacco, and production of mechanic devices are traditional sectors in non-oil export. The estimation results of the model indicate that both, traditional and non-traditional non-oil export sectors have economically and statistically significant impact on non-oil GDP.

    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.

    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.

    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)

    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.

    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.

    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.

    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)

    The monopoly of the state petroleum company Pertamina is expected to be threatened by major reforms in Indonesia's oil and gas regulation. The new legislation is expected to tackle issues such as the opening up of the industry to private sector competition, the subsidy of the domestic market and fresh regulatory structures. It is likely that Pertamina will become a privatised limited liability company.

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

    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.

    Full Text Available The agribusiness industry and agricultural machinery as well as the internationalization of companies are subjects of growing interest. Thus, a case study of a company in the sector of machinery and implements allowed the analysis of the movements of internationalization under the aspects of strategy, entry mode and challenges of internationalization. The study of the theories and the case study allowed a visualization of their application in practice. The literature review explored the themes internationalization, internationalization strategies, entry modes and challenges of internationalization. The data, qualitative and descriptive, were obtained from semi-structured interviews with the export manager and supplemented by secondary data published on the company’s website. The content analyzes of the data showed that the company is in a primary level of internationalization. However, it also presents strategic orientation toward an internationalization process. The development of this paper can serve as a discussion for further development of internationalization theories and also as a reference in the agribusiness industry to understand this process.

    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 Abstract Background The ability of mosquitoes of the genus Aedes and its allies, such as Stegomyia, to transmit diseases such as dengue and yellow fever, makes them important in public health. This study aims to evaluate the use of the essential oil of Brazilian pepper in biological control of by assessing and quantifying the larvicidal effect against S. aegypti, the only available access to dengue control, and test its risk of genotoxicity with Salmonella typhimurium as an indicator of safety for its environmental use. Results The density of the oil was 0.8622 g mL-1. Gas chromatography coupled with mass spectrometry revealed six major constituents: δ-3-carene (55.43%, α-pinene (16.25%, sylvestrene (10.67%, germacrene D (2.17, β-myrcene (1.99%, and isoterpinolene (1.4%. The minimum inhibitory dose to larvae development was 862.20 μg mL-1. The median lethal dose (LD50 of the essential oil for larvae was between the concentrations of 172.44-344.88 μg mL-1. There was no mutagenic risk for the essential oil, since there were no biochemical or morphological changes in S. typhimurium after exposure to the essential oil. Conclusions The minimum inhibitory essential oil concentration and the median lethal dose pointed to the value of the use of water dispersions of Brazilian pepper essential oil as an environmental safe natural larvicidal for S. aegypti.

    The Office for Partnerships in Advanced Skills (OPAS), Western Office organized this conference to discuss critical human resource issues in the oil and gas sector. In order to gain a broad perspective and different viewpoints, OPAS brought together representatives from the oil and gas industry, academia, the Alberta Energy and Utilities Board, and Alberta's Ministry of Human Resources and Employment. Topics of discussion included market trends, skills shortages and training development needs to respond to difficulties in recruiting in the areas of thermal enhanced oil recovery technologies and unconventional gas technologies. An 18 question survey conducted prior to the symposium revealed that the majority of respondents do not think that the current post secondary curriculum adequately meets the oil and gas industry's employment skill requirements. The challenges in designing and implementing industry specific programs were then discussed along with the timeline needed to develop an appropriate program and get graduates into the marketplace. The recommended initiatives resulting from the symposium discussions were then presented. refs., tabs., figs.

    The present paper discuss the development of different insulating oils for electric power transformers during the last hundred years and analyze comparatively the potential for the use of vegetable oils as a source for green dielectric oils, due to its high level of biodegradability, nontoxic, material compatibility, good electric strength and insulation properties, long-term oxidative and thermal stability, relatively low pour point and reasonable cost. Based on these premises, the authors developed a new type of insulating fluid based on Brazilian vegetable oils never used before for this purpose. This product is competitive with similar and patented products developed from canola and soya vegetable oils. Recently a new patent related with the process for the production of this fluid was submitted to the World Industrial Property Organization - WIPO. (author)

    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

    As the occurrence of heavy and extra-heavy oils increases sensitively, their participation in the refineries feeding also becomes greater. Heavy oils usually have lower price than a light one, because they produce lower quality derivatives and it's more difficult to meet the specifications. Crude oils are a complex mixture, mostly compounded by carbon and hydrogen and also by impurities like sulfur, nitrogen, oxygen and metals. Sulfur is the third most abundant component of crude oils, following carbon and hydrogen. In general there is a strong positive correlation between the concentrations of polar compounds (aromatics, resins and asphaltenes), and the sulfur content. This work presents graphically sulfur content and polar compounds concentrations for Brazilian and foreign heavy and extra-heavy oils (< 20 deg API). The results of the data analysis indicate that Brazilian crude oils behave differently from foreign heavy and extra-heavy oils. (author)

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

    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)

    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)

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

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

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

    The 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

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

    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.

    Three oil-producing fields are now onstream in the Dutch sector of the North Sea, an area which until about three years ago produced only natural gas. Union Oil Company of The Netherlands and Nedlloyd Energy B.V. are partners in the three fields, located in Block Q/1. Union is operator. Oil was first discovered in 1979 in an exploratory well about 40 km west of Den Helder. Confirmation drilling established the Helm field. About a year later, Helder field was discovered 6 km northwest of Helm. Production licenses for the two fields were granted in mid-1981 and production began from both fields in late September 1982. A third field in the Q/1 block, Hoorn, was discovered in 1980 and went onstream at the end of July 1983. In late summer 1983, Helm and Helder were producing a total of about 15,000 b/d, and Hoorn output was up to about 20,000 b/d one month after coming onstream. Development of the finds moved fast; for example, Hoorn field was put onstream 37 days ahead of schedule, according to a Union spokesman. Several factors were responsible for meeting--or beating--construction and development schedules, including: Cooperation of the Dutch government made permitting and other procedures move quickly. An integrated deck concept was used for platform design, reducing fabrication time and offshore construction time. Platforms for all three fields were identical, with only minor modifications made to handle different throughputs. Full approval to proceed with the development of Helm and Helder was obtained in July 1981, jackets and deck were delivered 1 year later and installed in August 1982. The Hoorn platform deck was delivered in June 1983, and started up at the end of July.

    1999-12-15

    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.

  13. Dynamics of risk management in the regulated contracting environment of the Brazilian electrical sector; Dinamica da gestao de riscos no ambiente de contratacao regulada do setor eletrico brasileiro

    Souza, Fabio Cavaliere de

    2008-11-15

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

    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.

    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

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

    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.

    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)

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

    Rwabizambuga, Alexis

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

    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 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.

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

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

    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: Black-Right-Pointing-Pointer SEA can inform and improve the efficacy and efficiency of project EA offshore Black-Right-Pointing-Pointer Scope and deliverables of SEA offshore often differ from stakeholder expectations Black-Right-Pointing-Pointer Considerable variability in influence of SEA output beyond licensing decisions Black-Right-Pointing-Pointer Sector-based SEA offshore is often too restrictive to generate expected benefits.

    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.

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

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

    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.

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

    As foreign investment in the Russian oil industry is now being permitted for the first time, many international companies are experiencing difficult and unreceptive conditions. This article suggests that the Russian domestic oil industry must seek to restructure itself in an orderly fashion, so that foreign investors are treated on a rational, open and fair basis. However western oil companies will need, alongside these changes, to invest in existing operations or actively seek the participation of local partners if privatization and co-venturing are to be a success.

    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.

    This paper evaluated the extent to which Canada's oil and gas companies are now responding to the challenges of climate change. The analysis was published to assist companies and investors in reducing the risks associated with climate change. The study used a methodology that drew on leading sources in the field of corporate responses to climate change in order to build climate risk metrics for the oil and gas industry. The study assessed the management systems, action plans, performance and transparency of 48 Canadian oil and gas companies in order to determine the extent to which the companies are preparing for the future. The study found that the vast majority of Canadian oil and gas companies have failed to take action to reduce greenhouse gas (GHG) emissions, and only 7 companies factored the cost of carbon into capital allocation decisions. Many companies have failed to conduct inventories of GHG emissions. Only 13 of 48 companies disclosed GHG emissions to the public. The study also determined that only 4 of the 50 companies assessed in the study were responding appropriately to risks associated with climate change. Canadian companies included Shell Canada and Suncor. Both companies had established comprehensive management systems, strategies and renewable energy investments, and had high levels of transparency. 19 refs.

    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)

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

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

    2017-01-01

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

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.

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

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

    Science.gov (United States)

    Persson, U Martin; Henders, Sabine; Cederberg, Christel

    2014-11-01

    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.

    2011-07-01

    This report explores crucial issues pertaining to energy security in India and suggests the objective of charting a roadmap for the future. India's fragile energy security is under severe pressure from its rising dependence on imported oil, regulatory uncertainty and opaque natural gas pricing policies, small pool of skilled manpower and poorly developed upstream infrastructure and dependence on fossil fuels as the dominant source of energy in the near future. To meet the growing energy demand over the next few years, India will have to enhance its energy security by procuring energy supplies at affordable prices. While the country has surplus refining capacity and is an exporter of petroleum products, major investments will have to be made in the domestic upstream industry and to acquire hydrocarbon reserves abroad. In India currently, a move towards a diversified fuel basket, together with a focus on efficient exploration and consumption of energy resources, is needed. Additionally, key areas of action are: Accelerated development of energy infrastructure; Human resource development; and Technological upgrade. A more conducive policy environment coupled with an effective regulatory regime is, without doubt, the basis for accelerated growth of domestic energy resources. Energy security needs integrated action by all stakeholders.

    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)

    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

    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)

    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. This study provides with top managers key insight into the CSFs influencing risk management to proper resource allocation.

    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.

    Full Text Available In vitro studies have been carried out to establish the nutritional differences between crude and refined vegetable oils; however, the impact of the consumption of these foods on metabolism, in particular the effect of buriti oil, needs to be further evaluated. The aim of this study was to evaluate the biochemical and murine parameters and the vitamin A and E status in young rats fed with diets supplemented with crude or refined buriti oil. The animals (n = 30 were randomized into three groups receiving diet added of soybean oil (control, crude buriti oil (CBO and refined buriti oil (RBO for 28 days. Rats fed with diet added of refined buriti oil (RBO showed reduced total cholesterol (up to 60.27%, LDL (64.75%, triglycerides (55.47% and enzyme aspartate transaminase (21.57% compared to those fed with diet added of crude oil. Serum and hepatic retinol and tocopherol were higher by two to three times in CBO and RBO groups compared to the control group, but no differences were observed for murine parameters. The results indicate that buriti oil is an important source of the antioxidant vitamins A and E, and refined buriti oil is suggested as alternative to improve the lipid profile of healthy rats.

    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.

    2001-07-01

    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)

    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

    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.

    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.

  1. 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.

    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)

    Full Text Available This cross-over study was conducted to assess the germ-killing efficacy of an essential oil mouthrinse (EOM by determining the blood levels of microorganisms associated with induced bacteremia and investigating the prevalence of this event in Brazilians with mild-to-moderate gingivitis. Thirty four (31.19% subjects positive for bacteremia induced by chewing a ration of apple were enrolled out of 109 screened subjects (50 males and 59 females. A difference of at least 10 colony forming units between the pre- and post-insult blood samples was defined as a positive result. For the following two weeks patients underwent a toothbrush plus fluoride dentifrice normalization period, and were then scheduled for the Phase I protocol as follows. At baseline I, subjects were instructed to chew a new apple ration, had new blood samples taken before and after this oral stimulus, and were randomly assigned to an experimental essential oil (n = 17 or placebo (P mouthrinse (n = 17 treatment for 2 weeks. These procedures were repeated at the end of Phase I and then followed by a two-week wash-out period (tooth brushing with fluoride dentifrice. Bacteremia was again induced at baseline and at the end of Phase II, when subjects were crossed-over to the other EOM or placebo groups. Bacterial count differences between baseline and 2-week post-treatment (EOM versus P in the blood samples collected were assessed by analysis of covariance. Mean aerobic counts decreased by 45.8%, whereas mean anaerobic counts decreased by 63.3% after EOM treatment. After the P treatment, aerobic bacteria increased by 28.4% and anaerobic bacteria decreased by 18.5%. This study validated this novel methodology and showed that the germ-killing action of EOM significantly reduced bacteremia.

    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.

    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)

    2006-03-15

    Responses to the terrorist attacks of September 11 have enhanced a number of national security policy programs, standards and resources to assess, advise, and protect critical energy infrastructure in Canada. It is expected that resolutions related to energy security and interdependence will reflect private sector concerns and solutions. However, the private energy sector does not currently qualify for sponsorship in the Industrial Security Policy Program. This paper argued that the security systems and standards in place in the Canadian private energy sector should be reinforced by government policies. A joint commission model developed by government agencies with the participation of the private sector was recommended. It was suggested that academic, security and intelligence professionals within government departments that provide services for energy infrastructure protection share their expectations under the leadership of the Canadian Centre of Intelligence and Security Studies. An outline of Canada's industrial security policy and program was presented, as well as details of the role of the industrial security advisory board. 31 refs.

    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 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.

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.

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

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

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

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

  18. 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.

    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.

    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)

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

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

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

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

    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.

    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.

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

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

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

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

    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)

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

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

    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)

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

    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.

    This paper describes the current energy sector in Ecuador, its present structure, the oil industry, subsidies, and renewable energy, focusing on the evolution and reform of the electricity sector. Currently, 86% of the primary energy originates from nonrenewable sources. In 2005, the gross electricity generation was 15 127 GWh (45.5% hydropower, 43.11% thermal, and 11.39% imported). Ecuador is the fifth largest oil producer in South America but lacks sufficient oil refining capacity. Reserves of natural gas (NG) are small, and most of NG is produced from oil fields without energy recovery. Several projects are underway to increase the utilization of NG and renewable energies to meet Ecuador commitments to the Kyoto Protocol. (author)

    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 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

    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.

    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.

A partir de um estudo multicaso com três atacadistas e duas indústrias fornecedoras, foi possível demonstrar as principais características do processo de seleção e avaliação dos fornecedores de marcas próprias.The evolution of the wholesaling sector in the past few years has made possible that some traditional corporate functions of the supply chain were significantly influenced by its marketing strategies. The literature shows a deep relation between own brand strategies and the activities of supply management. It happens because the development of own brands makes the wholesaler a very careful buyer that aims at selecting and evaluating the suppliers in order to obtain the best performance of the own brand products. In this way, the main objective of this paper is to analyse the impact of the supply management in the own brand strategy in wholesalers, analysing the procedures and criteria used by wholesalers to select and evaluate own brand suppliers. From a multicase study with three wholesalers and two suppliers, all Brazilian companies, it is possible to demonstrate the main

    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)

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

    Science.gov (United States)

    Neupert, R F

    1991-04-01

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

  14. Are public officials really less satisfied than private sector workers?A comparative study in Brazil

    Directory of Open Access Journals (Sweden)

    Renata Borges

    2013-12-01

    Full Text Available This research aims to compare the public and private sectors with regard to satisfaction at work. We conducted a survey with 670 professionals from both sectors in Brazil. The results of variance analysis confirm previous researches indicating that public officials are less satisfied with their work than private sector workers. However, this result does not repeat when we evaluate the satisfaction dimensions. For instance, public officials reported being more satisfied than private sector workers with regard to social environment and work stability. Unexpectedly, the results suggest that there is no difference between these sectors when we analyze the satisfaction with supervision. Therefore, this article is relevant for Brazilian managers, by offering an empirical research on the distinction between public and private. The article also discusses the theoretical implications, since Brazilian findings do not completely support the international literature.

    2017-03-01

    The paper examines the impacts of financial development on sectoral carbon emissions (CO2) for environmental quality in Malaysia. Since the financial sector is considered as one of the sectors that will contribute to Malaysian economy to become a developed country by 2020, we utilize a cointegration method to investigate how financial development affects sectoral CO2 emissions. The long-run results reveal that financial development increases CO2 emissions from the transportation and oil and gas sector and reduces CO2 emissions from manufacturing and construction sectors. However, the elasticity of financial development is not significant in explaining CO2 emissions from the agricultural sector. The results for short-run elasticities were also consistent with the long-run results. We conclude that generally, financial development increases CO2 emissions and reduces environmental quality in Malaysia.

    2015-07-01

    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)

    Full Text Available This study were examined relationship between bank credits and investment growth of agricultural sector in Iran during the period of 1982-2011 by auto regressive distribution lag bounds test approach. Basically, the growth investing of the agricultural sector in Iran is related to oil revenues, bank credits, value added of agriculture sector and capital stock. The results confirm the existence of a long-run relationship between variables in model. In addition, according to the results, bank credit is the most significant variable in explaining the growth investing, so that increases access to it will encourage growth investment of the agricultural sector in Iran. The estimations show that elasticity of bank credits, oil revenues, stock investment and value added are 0.103, 0.015, 0.049 and -0.058 in the agricultural sector respectively.

    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.

    2013-11-01

    Obesity prevalence in the Brazilian adult population is 12.5% among men and 16.9% among women. Obesity control has been a subject of concern in Brazilian health policies since the publication of the National Food and Nutrition Policy in 1999. The initiatives include a comprehensive national intersectorial plan for obesity prevention and control focused on confronting its social and environmental causes, development of a food and nutrition education framework aimed at intersectorial public policies in the food and nutritional security field, promotion and provision of healthy food in school environments (linked to family farming), structuring nutrition actions in primary healthcare in the national healthcare system, promoting community physical activity, food regulation and control, and encouragement of public participation and food control. We conclude that several initiatives have been developed in Brazil to deal with the challenge of implementing an intergovernmental, intersectorial response to reverse the rising overweight and obesity rates. The success of this response will depend on a governance model that promotes joint and integrated action by different sectors and active participation of society to consolidate the actions, places and laws that protect health and promote healthy lifestyles.

    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 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.

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

    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.

    2012-10-01

    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.

    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.

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.

    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)

    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.

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

    This paper is a translated, edited version of a lecture given at Business Consultative Meeting of Eight-Nation Energy Ministers` Conference convened in Moscow in March, 1998. This is a Russian investor`s opinion about the conditioning for the attraction of private sector investors to Russia`s energy industry. The economic development of Russia will depend on the magnitude and efficiency of the investment in oil and gas projects. So as to overcome the current inactivity of oil industry, Russia will need an investment of 6 to 20-billion dollars a year. Furthermore, according to the micro-economy level calculation, the required investment will be 130 to 140-billion dollars a year. Under the circumstances, what is necessary is to work out conditions to be most favored by the investors. For the attraction of an increased number of investors, two methods are under consideration. One involves the improvement of the currently valid underground resources utilization system (licensing system), and the other involves the formulation of a competitive underground resources utilization system based on the mechanism of agreement on products distribution. 4 figs., 1 tab.

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

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

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.

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

    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.

    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.

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

    2011-12-01

    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.

    Subramanyam, Veena

    Alberta is the third largest economy in Canada and is expected to grow significantly in the coming decade. The energy sector plays a major role in Alberta's economy. The objective of this research is to develop various greenhouse gas (GHG) mitigations scenarios in the energy demand and supply sectors for the Province of Alberta. This is done through an energy-environment planning and forecasting tool called Long Range Energy Alternative Planning system model (LEAP). By using LEAP, a sankey diagram for energy and emission flows for the Province of Alberta has been developed. A reference case also called as business-as-usual scenario was developed for a study period of 25 years (2005-2030). The GHG mitigation scenarios encompassed various demand and supply side scenarios. In the energy conversion sector, mitigation scenarios for renewable power generation and inclusion of supercritical, ultra-supercritical and integrated gasification combined cycle (IGCC) plants were investigated. In the oil and gas sector, GHG mitigation scenarios with carbon capture and sequestration (CCS) option were considered. In Alberta's residential and commercial sector 4-6 MT of CO2 equivalents per year of GHG mitigation could be achieved with efficiency improvement. In the industrial sector up to 40 MT of CO2 equivalents per year of GHG reduction could be achieved with efficiency improvement. In the energy conversion sector large GHG mitigation potential lies in the oil and gas sector and also in power plants with carbon capture and storage (CCS) option. The total GHG mitigation possible in the supply side option is between 20--70 MT CO2 equivalents per year.

    The sinking of the Don Pedro merchant ship in 2007 near the island of Ibiza is a good example of the extreme sensitivity of the tourism sector to oil spills. Despite the limited scale of the spill (only some 20 tonnes), its minimal ecological impact, and the rapid deployment of personnel and equipment to contain it, the accident nonetheless caused significant economic damage to the island's tourism sector. This particular case demonstrates the importance of the beach as a factor of production in the holiday tourism sector, and the capacity of even small amounts of oil to render it unusable and cause heavy losses to holiday firms.

    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.

    Wettre, C.; Reistad, M.; Hjøllo, B.Å.

    Simulation of oil drift has been an ongoing activity at the Norwegian Meteorological Institute since the 1970's. The Marine Forecasting Centre provides a 24-hour service for the Norwegian Pollution Control Authority and the oil companies operating in the Norwegian sector. The response time is 30 minutes. From 2002 the service is extended to simulation of oil drift from oil spills in deep water, using the DeepBlow model developed by SINTEF Applied Chemistry. The oil drift model can be applied both for instantaneous and continuous releases. The changes in the mass of oil and emulsion as a result of evaporation and emulsion are computed. For oil spill at deep water, hydrate formation and gas dissolution are taken into account. The properties of the oil depend on the oil type, and in the present version 64 different types of oil can be simulated. For accurate oil drift simulations it is important to have the best possible data on the atmospheric and oceanic conditions. The oil drift simulations at the Norwegian Meteorological Institute are always based on the most updated data from numerical models of the atmosphere and the ocean. The drift of the surface oil is computed from the vectorial sum of the surface current from the ocean model and the wave induced Stokes drift computed from wave energy spectra from the wave prediction model. In the new model the current distribution with depth is taken into account when calculating the drift of the dispersed oil droplets. Salinity and temperature profiles from the ocean model are needed in the DeepBlow model. The result of the oil drift simulations can be plotted on sea charts used for navigation, either as trajectory plots or particle plots showing the situation at a given time. The results can also be sent as data files to be included in the user's own GIS system.

    2010-08-01

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

  17. 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.

    The construction sector is characterized by high complexity due to several factors. There are a lot of processes within the building sites and they need the use of different materials with the help of appropriate technologies. Traditional materials have evolved and diversified, meanwhile new products and materials appeared and still appear, offering services which meet user needs, but that often involve risks to the health of workers. Research in the field of materials, promoted and carried out at various levels, has led to interesting results, encoded in the form of rules and laws.

    How much of the total Norwegian emissions to air comes from the petroleum sector? What is the Norwegian petroleum industry's contribution to the discharges to sea? How do the Norwegian authorities manage the environmental aspects relating to the petroleum industry? What does nmVOC mean? In co-operation with the Norwegian Petroleum Directorate the Norwegian Ministry of Petroleum and Energy issues this publication to answer questions such as these. We furthermore wish to provide comprehensive information about the environmental aspects relating to the Norwegian oil and gas operations. It is also important to demonstrate that the efforts to improve environmental efficiency in this industry is a continuous process and that measures have already been implemented to this effect. Each year we take a closer look at one topic which is of concern to the petroleum industry. In light of the new protocol under the Convention of Long-range Transboundary Air Pollution, we wish to focus on the offshore sectors emission of NO{sub x} in this issue and on the possibilities and challenges we face in this context. This publication also contains a section containing factual data, which i.a. describes the status of discharges and emissions, environmental effects and measures to reduce the emission of CO{sub 2}, NO{sub x}, nmVOC and the discharge of oil and chemicals. We hope that a publication like this will increase the public's general knowledge of how the petroleum industry addresses environmental issues. An important task of the Ministry of Petroleum and Energy is to help formulate general guidelines and measures in areas where energy policy and environmental policy interact. It is furthermore our aim to help Norway combine her role as a major oil producer of energy with the role of being a leader in the protection of the environment.

  4. Chiral Dark Sector

    Co, Raymond T; Nomura, Yasunori

    2016-01-01

    We present a simple and natural dark sector model in which dark matter particles arise as composite states of hidden strong dynamics and their stability is ensured by accidental symmetries. The model has only a few free parameters. In particular, the gauge symmetry of the model forbids the masses of dark quarks, and the confinement scale of the dynamics provides the unique mass scale of the model. The gauge group contains an Abelian symmetry $U(1)_D$, which couples the dark and standard model sectors through kinetic mixing. This model, despite its simple structure, has rich and distinctive phenomenology. In the case where the dark pion becomes massive due to $U(1)_D$ quantum corrections, direct and indirect detection experiments can probe thermal relic dark matter which is generically a mixture of the dark pion and the dark baryon, and the Large Hadron Collider can discover the $U(1)_D$ gauge boson. Alternatively, if the dark pion stays light due to a specific $U(1)_D$ charge assignment of the dark quarks, th...

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

    1998-12-31

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

    Full Text Available This paper aims at analyzing international trade in labor-intensive sectors in the 2000s, with a special reference to the Brazilian case. Therefore, we use the constant market share analysis to compare several countries’ export performance. It was observed that Asian countries emerged strengthened from this period. Brazil had a mediocre performance, losing market-share in global markets. Moreover, competition from Asian economies and even from the small Central American countries, such as Guatemala and El Salvador, has undermined the penetration of Brazilian exports in its major trade partners, which are North America and South America.

Observou-se que tão importante quanto contribuir para a geração e formação do PIB, de emprego, impostos, salários e balança comercial é o poder que um setor produtivo tem a mais que o outro de multiplicar estes indicadores quando uma unidade monetária é gasta a mais pelos consumidores finais na demanda por produtos deste determinado setor. Os resultados indicaram que o setor florestal é um dos setores da economia brasileira que apresentou os maiores efeitos multiplicadores para os indicadores socioeconômicos, sendo superiores aos de outros como o da indústria automobilística, de equipamentos elétricos e eletrônicos, de máquinas e equipamentos e de produtos químicos e petróleo.This study evaluated the important role the forestry sector plays in the Brazilian economic development by means of the multisector general economic equilibrium models, through the analyses of the Input-Output Matrix (IOM and the Social Accounting Matrix (SAM.

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

    2012-09-01

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

    Turbidites and associated deep-water facies comprise the most important petroleum reservoirs in Brazil. They contain in place volumes of 57.2 billion bbl of oil, and 27.5 trillion cubic feet of gas, and total reserves of 12.5 billion bbl of oil, and 8.3 trillion cubic feet of gas. Brazilian petroleum-bearing turbidites occur in Carboniferous/Permian, glaciomarine pre-rift (interior cratonic) successions, Neocomian to Aptian, lacustrine rift successions and Upper Albian to Lower Miocene, marine passive margin successions. Most of the petroleum accumulations are distributed along the eastern Brazilian margin, which tectonic and sedimentary evolution is linked to the Neocomian breakup of Gondwana and the subsequent opening of the South Atlantic Ocean. Turbidites comprise 553 production zones from 171 oil and/or gas fields, mostly concentrated in the Campos, Reconcavo, Sergipe/Alagoas, and Espirito Santo basins. This paper presents an overview of the sedimentary facies, high-resolution stratigraphy, sand body geometry, and reservoir heterogeneities of the major types of Brazilian deep-water reservoirs, which include gravel/sand-rich, turbidite channel complexes, though-confined, gravel/sand-rich turbidite lobes, gravel/sand-rich turbidite and debrite aprons, deposits of sand-rich, lacustrine density underflows, deposits of sand/mud-rich debris flows, and deposits of sandy bottom currents.

    Full Text Available The 2008 economic crisis challenged accounting, either demanding recognition and measurement criteria well adjusted to this scenario or even questioning its ability to inform appropriately entities’ financial situation before the crisis occurred. So, our purpose was to verify if during economic crises listed companies in the Brazilian capital market tended to adopt earnings management (EM practices. Our sample consisted in 3,772 firm-years observations, in 13 years – 1997 to 2009. We developed regression models considering discretionary accruals as EM proxy (dependent variable, crisis as a macroeconomic factor (dummy variable of interest, ROA, market-to-book, size, leverage, foreign direct investment (FDI and sector as control variables. Different for previous EM studies two approaches were used in data panel regression models and multiple crises were observed simultaneously. Statistics tests revealed a significant relation between economic crisis and EM practices concerning listed companies in Brazil in both approaches used.

    Full Text Available Cleaner Production (CP is gaining emphasis in both world and Brazilian production sectors. Nature’s warnings indicating the exhaustion of any capacity to absorb and regenerate waste, stricter legislation regarding pollution emitters, market competitiveness associated with environmental and social responsibility cause concerns and lead to actions to reduce aggressions against the environment. This paper shows evidence of this concern and presents cases in which a large automotive industry, acting as a partner to suppliers, promotes changes in how it delivers its products, eliminating large cardboard, plastic and wood packaging. A small company had a similar initiative, reducing the use of cardboard and plastic packaging. More important is the revelation of a widely dispersed, yet growing and incremental movement of responsibilities among companies.The benefits of cleaner production implementation were evaluated by confronting environmental and financial assessment. For the ambient evaluation, it will be used methodology of Material Intensity (Wuppertal Institute, a.

  14. Abandoned Texas oil fields

    Energy Technology Data Exchange (ETDEWEB)

    1980-12-01

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

  15. Environment 2002. The Norwegian petroleum sector

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2002-07-01

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

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

    Energy Technology Data Exchange (ETDEWEB)

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

    2012-07-01

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

  17. Light Chiral Dark Sector

    CERN Document Server

    Harigaya, Keisuke

    2016-01-01

    An interesting possibility for dark matter is a scalar particle of mass of order 10 MeV-1 GeV, interacting with a U(1) gauge boson (dark photon) which mixes with the photon. We present a simple and natural model realizing this possibility. The dark matter arises as a composite pseudo Nambu-Goldstone boson (dark pion) in a non-Abelian gauge sector, which also gives a mass to the dark photon. For a fixed non-Abelian gauge group, SU(N), and a U(1) charge of the constituent dark quarks, the model has only three free parameters: the dynamical scale of the non-Abelian gauge theory, the gauge coupling of the dark photon, and the mixing parameter between the dark and standard model photons. In particular, the gauge symmetry of the model does not allow any mass term for the dark quarks, and stability of the dark pion is understood as a result of an accidental global symmetry. The model has a significant parameter space in which thermal relic dark pions comprise all of the dark matter, consistently with all experimenta...

  1. Proposal of a Methodology of Stakeholder Analysis for the Brazilian Satellite Space Program

    Directory of Open Access Journals (Sweden)

    Mônica Elizabeth Rocha de Oliveira

    2012-03-01

    Full Text Available To ensure the continuity and growth of space activities in Brazil, it is fundamental to persuade the Brazilian society and its representatives in Government about the importance of investments in space activities. Also, it is important to convince talented professionals to place space activities as an object of their interest; the best schools should also be convinced to offer courses related to the space sector; finally, innovative companies should be convinced to take part in space sector activities, looking to returns, mainly in terms of market differentiation and qualification, as a path to take part in high-technology and high-complexity projects. On the one hand, this process of convincing or, more importantly, committing these actors to space activities, implies a thorough understanding of their expectations and needs, in order to plan how the system/organization can meet them. On the other hand, if stakeholders understand how much they can benefit from this relationship, their consequent commitment will very much strengthen the action of the system/organization. With this framework in perspective, this paper proposes a methodology of stakeholder analysis for the Brazilian satellite space program. In the exercise developed in the article, stakeholders have been identified from a study of the legal framework of the Brazilian space program. Subsequently, the proposed methodology has been applied to the planning of actions by a public organization.

  2. Regulation of solid waste management at Brazilian ports: analysis and proposals for Brazil in light of the European experience.

    2014-02-15

    With a coastline of 8500 km, Brazil has 34 public ports and various private terminals, which together in 2012 handled 809 million tonnes of goods. The solid wastes produced (from port activities, ships and cargoes) pose a highly relevant problem, both due to the quantity and diversity, requiring a complex and integrated set of practices resulting from legal requirements and proactive initiatives. The main Brazilian law on solid waste management is recent (Law 12,305/2010) and the specific rules on solid waste in ports are badly in need of revision to meet the challenges caused by expansion of the sector and to harmonize them with the best global practices. This paper analyzes the current legal/regulatory framework for solid waste management at Brazilian ports and compares this structure with the practice in Europe. At the end, we suggest initiatives to improve the regulation of solid wastes at Brazilian ports.

    1995-08-01

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

  9. Brazilian coral reefs in a period of global change: A synthesis

    Directory of Open Access Journals (Sweden)

    Zelinda M. A. N. Leão

    Full Text Available Abstract Brazilian coral reefs form structures significantly different from the well-known reef models, as follows: (i they have a growth form of mushroom-shaped coral pinnacles called "chapeirões", (ii they are built by a low diversity coral fauna rich in endemic species, most of them relic forms dating back to the Tertiary, and (iii the nearshore bank reefs are surrounded by siliciclastic sediments. The reefs are distributed in the following four major sectors along the Brazilian coast: the northern, the northeastern and the eastern regions, and the oceanic islands, but certain isolated coral species can be found in warmer waters in embayments of the southern region. There are different types of bank reefs, fringing reefs, isolated "chapeirões" and an atoll present along the Brazilian coast. Corals, milleporids and coralline algae build the rigid frame of the reefs. The areas in which the major coral reefs occur correspond to regions in which nearby urban centers are experiencing accelerated growth, and tourism development is rapidly increasing. The major human effects on the reef ecosystem are mostly associated with the increased sedimentation due to the removal of the Atlantic rainforest and the discharge of industrial and urban effluents. The effects of the warming of oceanic waters that had previously affected several reef areas with high intensity coral bleaching had not shown, by the time of the 2010 event, any episodes of mass coral mortality on Brazilian reefs.

    Full Text Available BACKGROUND: Most of the available instruments aimed to assess risk exposure associated with work-related musculoskeletal disorders were originally developed in English, which makes their use difficult in countries such as Brazil. OBJECTIVE: To test the clinimetric properties of the Quick Exposure Check (QEC instrument previously adapted into Brazilian-Portuguese. METHOD: The original version of the QEC was translated and cross-culturally adapted into Brazilian-Portuguese and tested with 107 workers in two sectors of a textile factory. The internal consistency and construct validity were tested using only baseline values from the participants while reproducibility (reliability and agreement was evaluated in a test-retest design with a seven-day interval. RESULTS: The adapted version presented appropriate levels of internal consistency (Cronbach's α=0.76; moderate intra-observer reliability (ICCs ranging from 0.41 to 0.60; moderate to substantial inter-observer reliability (ICCs ranging between 0.62 and 0.86. The standard error of the measurement (SEM ranged from 8.3 to 11.2 points. Moderate levels of construct validity (Pearson's r=0.38 were observed. CONCLUSIONS: The Brazilian version of the QEC has appropriate clinimetric properties for measuring different levels of exposure to ergonomics risk factors and can now be used by Brazilian researchers and Occupational Health professionals.

    1998-09-01

    This report gives a comprehensive, detailed statistical survey of the oil and gas activity on the Norwegian Continental Shelf. In the 4th quarter survey the investments for field development in 1998 are estimated to NOK 64 billion, which is 6.7 billion higher than the corresponding figures in the 1997 estimate. The increase is mainly due to the fact that more fields were approved for development throughout 1997. Even though the investments in 1998 will increase the most for field development, increases are also registered for exploration, fields on stream, onshore activities and pipeline transport. The investments for fields on stream are estimated at NOK 11.5 billion for 1998. Investments onshore for 1998 are estimated at NOK 3.6 billion, which is NOK 2.6 billion more than the estimate for 1997 from the 4th quarter 1996. The total investments for 1998 are estimated at NOK 7.4 for the pipeline transport sector, which is 1.6 billion higher than the corresponding estimate for 1997. The year 1997 appears to be a peak year for oil investments. 12 figs., 38 tabs.

    Full Text Available This paper analyzes the changes carried out by the organization of the Geographical Indications (GIs in the Brazilian wine sector. Initially, it discusses the role of grades and standards in the market governance. Then, based on research conducted in five Brazilian wine regions, it analyzes the construction of the GI Code of Practices. The results show that despite the institutional weaknesses that characterize the use of this intellectual property tool in Brazil, there is coherence in the rules established for the different contexts studied. This is consequence of a sectoral coordination process, which is characterized by the construction of a GI system that combines organizational and technological change with the re-valorization of socio-cultural attributes of the territories.

  19. Expanding worldwide urban solid waste recycling: The Brazilian social technology in waste pickers inclusion.

    Rutkowski, Jacqueline E; Rutkowski, Emília W

    2015-12-01

    'If an integrated urban waste management system includes the informal recycling sector (IRS), there is a good chance that more solid waste is recycled' is common sense. However, informal integration brings additional social, environmental, and economic benefits, such as reduction of operational costs and environmental impacts of landfilling. Brazil is a global best practice example in terms of waste picker inclusion, and has received international recognition for its recycling levels. In addition to analysing the results of inclusive recycling approaches, this article evaluates a selection of the best Brazilian inclusive recycling practices and summaries and presents the resulting knowledge. The objective is to identify processes that enable the replication of the inclusion of the informal recycling sector model as part of municipal solid waste management. Qualitative and quantitative data have been collected in 25 Brazilian cities that have contracted waste pickers co-operatives for door-to-door selective collection of recyclables. Field data was collected in action research projects that worked with waste pickers co-operatives between 2006 and 2013. The Brazilian informal recycling sector integration model improves municipal solid waste recycling indicators: it shows an increase in the net tonness recycled, from 140 to 208 t month(-1), at a much lower cost per tonne than conventional selective collection systems. Inclusive systems show costs of US$35 per tonne of recyclables collected, well below the national average of US$195.26. This inclusive model improves the quality of collected material and the efficiency of municipal selective collection. It also diminishes the negative impacts of informal recycling, by reducing child labour, and by improving the conditions of work, occupational health and safety, and uncontrolled pollution. Although treating the Brazilian experience as a blueprint for transfer of experience in every case is unrealistic, the results

    Full Text Available Abstract Background Differences in sex hormone levels among populations might contribute to the variation in breast cancer incidence across countries. Previous studies have shown higher breast cancer incidence and mortality among Japanese Brazilians than among Japanese. To clarify the difference in hormone levels among populations, we compared postmenopausal endogenous sex hormone levels among Japanese living in Japan, Japanese Brazilians living in the state of São Paulo, and non-Japanese Brazilians living in the state of São Paulo. Methods A cross-sectional study was conducted using a control group of case-control studies in Nagano, Japan, and São Paulo, Brazil. Participants were postmenopausal women older than 55 years of age who provided blood samples. We measured estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex hormone-binding globulin (SHBG by immunoradiometric assay. A total of 363 women were included for the present analyses, comprising 185 Japanese, 44 Japanese Brazilians and 134 non-Japanese Brazilians. Results Japanese Brazilians had significantly higher levels of estradiol, bioavailable estradiol, estrone, testosterone and free testosterone levels, and lower SHBG levels, than Japanese. Japanese Brazilians also had significantly higher levels of bioavailable estradiol, estrone and DHEAS and lower levels of SHBG and androstenedione than non-Japanese Brazilians. Levels of estradiol, testosterone and free testosterone, however, did not differ between Japanese Brazilians and non-Japanese Brazilians. These differences were observed even after adjustment for known breast cancer risk factors. We also found an increase in estrogen and androgen levels with increasing body mass index, but no association for most of the other known risk factors. Conclusions We found higher levels of

    Using the global database on physical and chemical properties of oils, the analysis of distribution of viscous, heavy, waxy and highly resinous oils in terms of volumes of their reserves was carried out. It is known that heavy and viscous oils account for slightly more than 33% of the total sample. Resinous and paraffin oils account for less than 30% of the total sample. The criteria necessary to classify oils as hard-to-recover oil reserves are determined. Features of physicochemical properties of these oils are studied under various conditions. The results obtained could be used to solve practical issues in the oil sector.

    2016-01-01

    We initiate a detailed investigation into the assembly of simple amplituhedron-like building blocks to obtain spaces of physical interest. In particular, we describe the geometric process through which the building blocks, which we call positivity sectors, glue together to form the desired geometries. Positivity sectors are seen to naturally segment the space describing the Lth power of the one-loop amplitude. In this way, we obtain a good understanding of how the geometric complexity of the building blocks can be washed out in the formation of larger spaces. Conversely, the tools we develop allow us to form spaces of ever greater complexity, a process which is crucial to the construction of the amplituhedron from its triangulations, which remains an important open question. We present the full boundary structure of all positivity sectors related to the three-loop amplituhedron. We also construct a practical algorithm that achieves the desired geometric assembly of positivity sectors, and make available suppo...

    The main development vector of a society is the energy. The solar energy is the main energy source on the planet earth. Brazil is a tropical country, and the incident solar energy on its soil (15 trillion MWh/year) is 20,000 times its annual oil production. Several uses of solar energy are part of our lives in a so natural way that it despised in the consumption and use energy balance. In Brazil, solar energy is used directly in many activities and not accounted for in Energy Balance (BEN 2007), consisting of a virtual power generation. This work aims to make a preliminary assessment of solar energy used in different segments of the Brazilian economy. (author)

    2010-09-15

    In this report present key achievements for each of the various cooperation countries. Oil for Development (OfD) assistance has been important for the ability of a country like Ghana to improve petroleum resource management on its most important oil and gas field, and to better safeguard that the petroleum activities are conducted in an environmentally sustainable way. Competence building on Increased Oil Recovery (IOR), and negotiation training have helped to increase both the resource extraction potential and the revenue generation potential of a more mature oil producing country like Iraq. Furthermore, OfD has contributed to improving the legislative frameworks in several of our cooperating countries, including Afghanistan, Cambodia and Madagascar, although it will take time before we can assess to what extent the laws have been implemented. OfD's strong focus on providing legal assistance reflects our belief that clear divisions of roles and firm legal mandates are prerequisites for good governance of the petroleum sector and for attracting serious investors. A lot of our capacity building took place through seminars and more tailored workshops with a national or regional scope. We believe that some of these events have significantly increased awareness as well as the level of debate among government institutions and civil society. The oil production accounting workshop in Nigeria and the NOC workshop in Timor-Leste are particularly valid examples. Timor-Leste also addressed other petroleum sector governance issues with a focus on including civil society and by the end of 2009 had nearly fulfilled all criteria for becoming Extractive Industries Transparency Initiative (EITI) compliant. It should be noted that OfD assistance only made a relatively small contribution to this process, which was very much nationally driven. Petroleum related environmental issues were addressed at different levels and from different angles. A thorough environmental needs

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

    This work studies the Zipf Law for cities in Brazil. Data from censuses of 1970, 1980, 1991 and 2000 were used to select a sample containing only cities with 30,000 inhabitants or more. The results show that the population distribution in Brazilian cities does follow a power law similar to the ones found in other countries. Estimates of the power law exponent were found to be 2.22 +/- 0.34 for the 1970 and 1980 censuses, and 2.26 +/- 0.11 for censuses of 1991 and 2000. More accurate results were obtained with the maximum likelihood estimator, showing an exponent equal to 2.41 for 1970 and 2.36 for the other three years.

    Full Text Available Abstract Background To evaluate medicine prices, availability and affordability in Brazil, considering the differences across three types of medicines (originator brands, generics and similar medicines and different types of facilities (private pharmacies, public sector pharmacies and “popular pharmacies”. Methods Data on prices and availability of 50 medicines were collected in 56 pharmacies across six cities in Southern Brazil using the World Health Organization / Health Action International methodology. Median prices obtained were divided by international reference prices to derive the median price ratio (MPR. Results In the private sector, prices were 8.6 MPR for similar medicines, 11.3 MRP for generics and 18.7 MRP for originator brands, respectively. Mean availability was 65%, 74% and 48% for originator brands, generics and similar medicines, respectively. In the public sector, mean availability of similar medicines was 2–7 times higher than that of generics. Mean overall availability in the public sector ranged from 68.8% to 81.7%. In “popular pharmacies”, mean availability was greater than 90% in all cities. Conclusions Availability of medicines in the public sector does not meet the challenge of supplying essential medicines to the entire population, as stated in the Brazilian constitution. This has unavoidable repercussions for affordability, particularly amongst the lower socio-economic strata.

    This study aimed to develop and validate a Brazilian version of the Food Craving Inventory (FCI-Br), adapted to the cultural-gastronomic context of Brazil, and to explore this behavior among adult Brazilians. The Study 1 population consisted of 453 adults from all regions of Brazil. Participants responded to a preliminary form of the instrument online. Exploratory factor analysis revealed an FCI-Br presenting 23 items and three factors: High Fat, Sweet Food and Traditional Meal. The FCI-Br overall reliability was considered adequate (α = 0.82), as were each of the sub-scales. The food items receiving higher average scores from the application of the instrument were chocolate (3.14 ± 1.28; women) and bread (2.94 ± 1.44, men). A significant association was observed between the specific-craving for Sweet Food and female respondents. Most participants reported experiencing more frequent episodes of food craving when alone (68.0%; n = 391) and during the afternoon (32.2%; n = 127) or evening (43.8%; n = 173) hours. Application of the FCI-Br in a population of 649 university students (Study 2) demonstrated a good adjustment of the model developed according to the Confirmatory factor analysis (χ(2)/gl = 2.82, CFI = 0.94; TLI = 0.93; RMSEA = 0.06). The current findings indicate that the FCI-Br has adequate psychometric properties to measure craving behavior with respect to specific food groups in the resident population of Brazil. The results of this study also shed light on the importance of considering the cultural diversity of a population when investigating eating behaviors.

    Natan Szuster

    2012-12-01

    Full Text Available The objective of this study was to investigate to what extent the IFRIC12 and ICPC01 accounting characteristics can influence in the formation of tariffs in the electricity sector in Brazil. The choice of this sector is justified by its economic relevance, its importance for the development of the country and mainly because it uses specific regulatory accounting rules. With a purely qualitative approach - justified by the incipient stage of the current research in this area – we conducted a theoretical study, focusing on qualitative information, through research of the literature and documents. The results show that the pricing model may change under the IFRIC 12 and ICPC 01 standards, which makes the effective application of these accounting standards in the environment regulated by the National Electric Energy Agency (ANEEL a difficult and complex task. The study also indicates that the main difference between the regulatory accounting system promoted by ANEEL and the international standards is the impossibility of recognizing regulatory assets and liabilities under the latter system. Therefore, the Brazilian electricity sector is one of those that may have its financial statements most affected by the convergence of Brazilian accounting standards to international standards.

    CERN Document Server

    2013-01-01

    Regulation of the Power Sector is a unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems. The need for generation to occur at the time of use occasioned by the impracticality of large-scale electricity storage coupled with constant and often unpredictable changes in demand make electricity-supply systems large, dynamic and complex and their regulation a daunting task. Conceptually arranged in four parts, this book addresses both traditional regulatory frameworks and also liberalized and re-regulated environments. First, an introduction gives a full characterization of power supply including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation and the third looks at the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute form the content of the fourth part. In a sector where regulatory design is the key driver...

    2016-09-01

    A lot of studies dealing with stock network analysis, where each individual stock is represented by a univariate time series of its closing price, have been published. In these studies, the similarity of two different stocks is quantified using a Pearson correlation coefficient on the logarithmic price returns. In this paper, we generalize the notion of similarity between univariate time series into multivariate time series which might be of different dimensions. This allows us to deal with economic sector network analysis, where the similarity between economic sectors is defined using Escoufier’s vector correlation RV. To the best of our knowledge, there is no study dealing with this notion of economic sector similarity. Two examples of data from the New York stock exchange will be presented and discussed, and some important results will be highlighted.

  14. Acausality from a Dark Sector

    CERN Document Server

    Carone, Christopher D

    2013-01-01

    Solutions to the hierarchy problem that require partners for each standard model particle often require that these states live at or above the electroweak scale, to satisfy phenomenological bounds. Partners to possible dark sector particles may be significantly lighter, due to the assumed weakness of the couplings between the dark and visible sectors. Here we consider the possibility that a dark sector might include light Lee-Wick particles. We present the formulation of a theory in which a dark photon and its Lee-Wick partner have kinetic mixing with hypercharge. We point out that the Lee-Wick partner of the dark photon will lead to an apparent violation of causality at small distance scales that might be discerned in low-energy experiments.

    2006-04-01

    Full Text Available The paper emphasises the role of the market-type mechanisms within the activity of the organisations from the public sector. The end of the 20th century was defined by the effects of the public sector reform. The public sector is placed within the cultural and political environment of each country and the reforms have aimed to redefine the structures of the state organisations in the economy and the relationships such as market-government, government-bureaucracy, government- citizens, bureaucracy-citizens, civil servants-politicians-citizens. The public sector reform, achieved at the managerial systems, organisational structures and regulations levels is accompanied by specific and structural reforms. Accepting the market-type mechanisms instead of bureaucratic mechanisms, meaning not the simple provision of public services but the creation of some governmental “actors”, functioning completely on commercial bases, supporting the development of the partnerships between the public and private sector, introducing privatisation is achieved in view of creating “the facilitating state”. We discuss about “facilities” such as citizens and society involvement in public businesses, making public administration more citizen-friendly and the state closer to the public need. The citizens’ involvement, as customers in the flow of the public service contributes to creating an organic ensemble characterised by two fundamental dimensions: level and type of influence of the customers and the private-public dichotomy. Synthesising, the relationships and market mechanisms enable to the public sector to get closer to the public needs and to create a modern administration based on efficiency, effectiveness and openness towards change.

    Several scenarios have been used to predict the need for electricity in Indonesia up to the year 2020, all of which should provide the best economic performance and the lowest damage to the environment. All scenarios have minimized the use of oil and natural gas as primary energy sources in favour of their use as foreign exchange generators and industrial raw materials. The alternative energy scenarios so developed shows the increasing use of coal, combined cycles, geothermal and hydro-power energy. Nuclear energy is apparently only considered whenever its selection becomes inevitable. The environmental issues associated with future energy generation necessitate serious consideration of the use of the latest technological state-of-the-art clean coal-fired power plants. Other types of alternative energy systems such as photovoltaic, wind energy, biomass, etc., are expected to be developed for site specific regions or remote areas where electricity grids are prohibitive economically. The Indonesian government has supported the use of NRSE (New and Renewable Sources of Energy) for electricity generation by introducing the SPPT, or Small Power Purchase Tariffs, intended to stimulate private sector participation in electricity by offering for purchase PLN (the State power company), using avoided cost calculation mainly for cogeneration systems and electric power from small power producers consisting of private sector and cooperative organizations.

    Tiago Fernandes Maranhao

    2011-05-01

    Full Text Available The aim of this paper is to review Gilberto Freyre’s ideas about futebol mulato and the way these ideas have spread the notion of the Brazilian mulatto as a symbol of a ‘racial democracy’, unique in Brazil, around the world. The notion first appeared in 1938 in an article by Freyre for the Diários Associados, an important Brazilian newspaper. Football (soccer was employed by Freyre as the special arena where the multiracial Brazilian nation could shine and show the world a different way of being, opposed to the white and ‘rational’ way of European football. In Freyre’s work, the so-called ‘football-art’ was compared to poetry, while the European style was equated with prose. This essay argues that Freyre’s ideas were useful in constructing the Brazilian identity, a nation of harmony in all its aspects, including the area of race, and how the idea of the mulatto has been used to minimise social disparities within Brazilian society. Freyre’s ideas remain contemporary; many Brazilian intellectuals still refer to these concepts. As well, the press in this huge country, and especially in World Cup years, uses the concepts of mulatto and football-art to characterize Brazil and differentiate it from other countries.

    Full Text Available This work focused on preparing and characterizing Brazilian bentonite clay through the use of quaternary ammonium salt so as to apply it as a sorbent for petroleum-derived fuels. Bentonite clay was organophilizated by the intercalation of quaternary ammonium salts such as cetyl-pyridinium chloride and benzalkonium chloride. The resulting materials were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, N2 physisorption and infrared spectroscopy techniques. The clay similarity with petroleum-derived fuels, gasoline and diesel oil were defined by sorption and swelling tests. The increase in basal spacing and the appearance of absorption bands related to the CH2 and CH3 groups confirm the efficiency of Brazilian organoclays. Removal percentages between 50 and 60 for benzene, toluene and xylene indicate the potential of organoclay in the remediation of areas contaminated by petroleum-derived fuels.

  2. Tectonic-sedimentary evolution of the eastern Brazilian marginal basins: Implications in their petroleum systems

    1993-02-01

    A geological survey of eastern Brazilian marginal basins using sedimentological, tectonic and geochemical data has been carried out. The almost 4000 km long set of basins can be classified as component of a typical divergent, mature Atlantic-continental margin. Based on their tectonic-sedimentary sequence, they can be linked to a single evolutionary history, which can be divided in three main stages: pre-rift, rift, and drift. The integration of all data allowed the characterization of two major petroleum systems that represent about 90% of the known Brazilian hydrocarbons reserves: (1) the rift (Early Cretaceous) and the drift (Late Cretaceous-Paleogene). With respect to the oil-in-place volume and production, the most significant one is the drift system associated with the siliciclastic deep water turbidites reservoirs deposited in bathyal environments. Such reservoirs are clearly controlled by a favorable relationship of stratigraphic and tectonic settings.

Its theoretical, conceptual positioning lies in those aspects related to risk management of the undertakings as instruments of support in decision making by executives in the tanker-maintenance business. The case-study method was used as an alternative methodology with a qualitative approach of an exploratory nature and, for the presentation of data, a descriptive format was chosen. Through the analysis of 75 risk events in projects of tanker docking it was possible to extract eight of the greatest relevance. The risk analysis facilitated the identification of actions aimed at their mitigation. As a conclusion it was possible to propose a risk-framework model in four categories, HSE (health, safety and the environment, technicians, externalities and management, designed to provide tanker-docking business executives and administrators, with evidence of actions to assist in their decision-making processes. Finally, the authors identified proposals for further study as well as showing the principal limitations of the study.

    This paper analyses the distribution of benefits between firms and consumers due to the price regulation of the Spanish energy sectors (electricity, oil fuels and gas) during the decade 1987-1997. To that effect, we compare the actual evolution of energy prices with alternate benchmarks in order to assess the potential existence of a pro-industry or a pro-consumer bias in the pricing policies followed by the regulator. Our results show a pro-industry-biased regulatory context, where consumers benefited very little from price control. The successive price adjustments over time allowed the companies to keep all the productivity gains and cost reductions and to increase their profitability rates relative to those achieved in the manufacturing sector.

  13. Oil palm seed distribution

    Durand-Gasselin Tristan

    2005-03-01

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

A unionism retrospective survey was carried out among 1,000 establishments in the manufacturing sector and its results were matched to performance indicators available from the Brazilian Industrial Surveys between 1990 and 2000. The results using the pooled data indicate that the relationship between unionism and some performance indicators, such as average wages, employment and productivity is non-linear (concave, so that a rise in unionism from low levels is associated with higher performance, but at a decreasing rate. Unions also reduce profitability. Establishments that introduced profit-sharing schemes increased their productivity and profitability overall and paid higher wages in more unionized plants.Este artigo analisa, pela primeira vez na literatura, o impacto dos sindicatos de trabalhadores em vários indicadores de desempenho econômico de firmas industriais brasileiras. Realizou-se uma pesquisa retrospectiva sobre a densidade sindical de 1000 estabelecimentos industriais brasileiros e seus resultados foram combinados aos indicadores de desempenho econômico da Pesquisa Industrial Anual (PIA de 1990 a 2000. Os resultados indicam que a relação entre a densidade sindical na firma e seus salários, emprego e produtividade, é não-linear, ou seja, um aumento no grau de sindicalização leva a um melhor desempenho, porém a taxas decrescentes. Observou-se, também, uma relação negativa entre sindicalização e rentabilidade. Finalmente, estabelecimentos que introduziram mecanismos de 'participação nos lucros' aumentaram sua produtividade e rentabilidade no período e pagaram maiores salários nas firmas onde o grau de sindicalização era maior.

    The Ministry of Health coordinates and orients in Brazil all the activities concerning the acquired immunodeficiency syndrome which is officially designated as AIDS. The first AIDS' case registered in Brazil was, by retrospective diagnosis, in 1981 but it was in 1982 that the first two diagnosis in live patients were made. The incidence is very high in this country that is among the ones where the higher number of cases are being registered. The great majority of the Brazilian cases occurs in the cities and in direct proportion to the population index. The groups of risk are the same universally known and a comparative increase of heterosexual transmission is noted, chiefly due to the use of injectable drugs and bisexuality of the male partners. Another problem that is being increased is pediatric AIDS, with raising importance of perinatal transmission as well as the use of injectable drugs and precocious prostitution in adolescence. The transfusional and haemophilic AIDS have proportionally decreased due to the control of blood products. The control and the orientation activity of the Ministry of Health is directed to varied points such as: compulsory cases notification, cooperation between public and private sectors, preventive and sexual orientation, freely delivered medication and laboratory tests including sigilous tests, lay and technical personnel preparation, diversified informative and educational campaigns. Trial tests with anti-HIV vaccines have begun to be performed. Multiple Reference Centers were officially established by the administration. Among them is to be quoted the Hospital Universitário Gaffrée Guinle of Rio de Janeiro where the authors work. It is credited for its intensive activity and pioneerism.

    This paper analyzes the evolution of five electricity distribution companies in the Northeast of Brazil using technical and financial indexes. Three privatized and two public firms were analyzed between 1997 and 2008. The financial indexes are related to the capacity of the business to generate value for shareholders, while the technical indexes are related to the quality of service provided to customers. We observed the privatized firms had their financial indexes improved after the privatization, increasing the value of the firm for the shareholders. However, there is no evidence that the privatization affected the quality of service provided to consumers.

    The open-plan office is a layout used in government offices in Brazil aimed at saving on space occupied and integrating employees. However, the design of these work-stations must follow the characteristics of tasks and their interrelationships, since adverse physical and organizational conditions may have a negative impact on work productivity. From this perspective, this study sought to identify, from the viewpoint of the ergonomics of the built environment, the adequacy of the open-plan government offices for financial auditing accounts and analyzing documents. Use was made of the Ergonomic Methodology for Evaluating the Built Environment--MEAC (in Portuguese) which systematically analyzes the physical space, by using a mix of physical-spatial assessments and tools for identifying how the environment is perceived. The MEAC was employed in three analytical phases of the physical aspects, namely: an analytical phase of the user's perception; a diagnostic phase; and a final phase of propositions.

    This paper presents a method for implementing multifunctional work teams in a footwear company that followed the Taylor/Ford system for decades. The suggested framework first applies a Learning Curve (LC) modeling to assess whether rotation between tasks of different complexities affects workers' learning rate and performance. Next, the Macroergonomic Work Analysis (MA) method (Guimarães, 1999, 2009) introduces multifunctional principles in work teams towards workers' training and resources improvement. When applied to a pilot line consisting of 100 workers, the intervention-reduced work related accidents in 80%, absenteeism in 45.65%, and eliminated work related musculoskeletal disorders (WMSD), medical consultations, and turnover. Further, the output rate of the multifunctional team increased average 3% compared to the production rate of the regular lines following the Taylor/Ford system (with the same shoe model being manufactured), while the rework and spoilage rates were reduced 85% and 69%, respectively.

    2006-07-01

    Full Text Available Using the RESCO 50 MHz backscatter radar (2.33° S, 44.2° W, DIP: –0.5, at São Luís, Brazil, we obtained Range Time Intensity (RTI maps covering the equatorial electrojet heights during daytime and evening. These maps revealed a scattering region at an altitude of about 108 km during the sunset period. The type of 3-m irregularity region we present here has not been reported before in the literature, to our knowledge. It was mainly observed around the Southern Hemisphere summer-solstice period, under quiet magnetic activity condition. The occurrence of this echo region coincides in local time with the maximum intensity of an evening pre-reversal eastward electric field of the ionospheric F-region. A tentative explanation is proposed here in terms of the theory of the divergence of the equatorial electrojet (EEJ current in the evening ionosphere presented by Haerendel and Eccles (1992, to explain the partial contribution of the divergence to the development of the pre-reversal electric field. The theory predicts an enhanced zonal electric field and hence a vertical electric field below 300 km as a consequence of the EEJ divergence in the evening. The experimental results of the enhanced echoes from the higher heights of the EEJ region seem to provide evidence that the divergence of the EEJ current can indeed be the driver of the observed scattering region.

    2004-07-01

    The oil and gas sector is Norway's largest industry by value creation and has been a key driving force in Norwegian economic development for several decades. Developments in the petroleum industry are crucial for the future progress of Norwegian society and will remain so. While the petroleum sector has so far been characterised by growth, we can now see the beginning of a gradual reduction in the level of activity. This will have significant spin-offs for other industries and consequences for the Norwegian economy as a whole. Thus, it is important to ensure that profitable petroleum activities are pursued in order to moderate the pace of decline. This publication provides a broad picture of Norway's petroleum activities, and covers most aspects of the industry. It presents useful information and statistics on the sector both for those already familiar with this business and for readers who know less about it. Since petroleum production began on the Norwegian continental shelf (NCS) in 1971, a total of 3.8 bn standard cubic metres of oil equivalent (scm oe) has been produced. This corresponds to just under 30 per cent of the original recoverable reserves, and so substantial oil and gas resources remain. The government's Report no 38 (2001-2002) to the Storting (the Norwegian Parliament) described a long-term scenario for the NCS in which estimates for recoverable reserves from the Norwegian Petroleum Directorate are recovered. It is very important to ensure that the long-term scenario is achieved based on due consideration of environmental and safety issues. Norway's role as a major energy producer must be reconciled with the ambition to be a pioneer in the environmental area. This goal has always characterized government policy towards the petroleum industry. The strong focus on the environment has created a positive trend in safeguarding environmental concerns on the NCS. Production of oil and natural gas liquids averaged 3.3 mill barrels a

    Full Text Available This paper aims to investigate the effects of investment in industrial R & D on the mobility of workers between firms and/or industrial sectors in Brazil, considering that the technological gap between the sectors can reduce the propensity for interindustrial labor mobility. Using panel data for the period 2003–2008, constructed from microdata RAIS-Migra and industry data from the Brazilian Technological Innovation Survey (PINTEC, the Annual Industrial Survey (PIA and input–output matrices, we estimate a multinomial logit model with random intercepts (GLLAMM – Generalized Linear Latent and Mixed Models. The main results show that the technological diffusion increases the chances of changing jobs, the technological variables have greater importance for unskilled workers than for skilled, and among non-intensive technology industries, the technological innovation can have positive impact on interindustrial mobility.

    Full Text Available This article seeks to analyze the dynamics of innovation in the economy. It analyzes the economic structure and social conditions involved in promoting technological progress and innovations. The economic structure is considered against the requirements of the innovator and the accumulation of capabilities dedicated to innovation. The social conditions are analyzed using the role of institutions in the innovation process. There is increasing effort to develop technological, scientific and innovative in recent years in Brazil, however, this effort is still generating codified and not tacit knowledge, it is centralized in public spending and universities. The private sector participates bit of effort to build national knowledge and depends on foreign technologies to innovate. The data also show a high dispersion of innovation (in product and process ranging sectors (industries, the main Brazilian states and regions and by size of company

  10. Communication in third sector organisations

    2010-01-01

    Full Text Available Third sector organisations favour the social development due to their capacity to produce human and social capital in society (Putman, 2001. In order to achieve social welfare third sector organisations need to produce a positive change in the relations among individuals, groups and institutions in a society. The expectations about the third sector organisations’ transparency and capacity to tackle social problems are increasing worldwide. In Mexico, this problematic is more complex because there is a low level of professionalism, transparency, accountability and participation culture in the organized civil society (ITAM, 2010. The development of the organized civil society in Mexico will depend to a great extent on its capacity to communicate its values to society and achieve a cultural and social change. Therefore, the third sector organisations must adopt strategic initiatives to reinforce their credibility and reputation, because the public and private donors are increasingly more demanding in their criteria to grant resources to social projects; and because the Mexican society has a low participation level and faces increasingly more complex social problems.

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

    Summary Palm oil is an important product in local diets and domestic markets in the South. The current attention for market quality standards and certification schemes in the palm oil sector has the risk to marginalise the role of palm oil in local food security and to direct public and private investments exclusively to industrial and export-oriented production systems. The rise of a variety of standards in the oil palm sector in recent times particularly the Roundtable for Sustainable Palm ...

    Full Text Available Context: Oils and butter of seed from Brazilian biodiversity are extending the range of innovative products for cosmetics development. They have a fat potential similar to skin composition, leading to the improved performance of these product. Aims: Improve the emulsions spreadability through prior screening of grease composition and studying the viscosity, and the emulsions accelerated stability. Methods: Emulsions were formulated using oils from semiarid plants from Bahia: Syagrus coronate, Pachira retusa, and Pachira aquatica, so as to compare them with oils already standard in the production of cosmetics. Spreadability and stability tests were made comparing the results. The same criteria were used with Amazon seed butter: Virola surinamensis, Butyrospermum parkii, Astrocaryum murumuru, Theobroma cacao and Theobroma grandiflorum. For the emulsions screening and performance, a system was developed for oil/ butter, following tests of accelerated stability, viscosity, and spreadability. Results: The combined system of spreadability was optimized using screening. Emollients containing oleic and palmitic acids, and light chain fatty acids obtained good spreadability. The oil emulsion containing Pachira retusa and Virola surinamensis butter had a higher viscosity. Conclusions: With high content of fatty acids such as oleic, palmitic or the light chain fatty acids obtain an appropriated appearance, texture, and spreadability for cosmetic use. Thus, oils with a low fatty acid content may be combined with butter that have a high fatty acid content and vice-versa. Analyzing and strategically combining grease composition, one can optimize the performance of cosmetic formulations.

    The present paper aims to assess long run energy savings for Brazil in the long term, according to economic scenarios established in Energy National Plan 2030 (PNE 2030). Methodological issues are presented as well as the basic assumptions for each scenario/end use consumption and related energy/electricity savings. In 2030, Brazilian industrial and transportation sectors still account for the large share of total energy savings (more than 80% in 2030). At the end of this paper, key points are analyzed in order to improve energy saving estimates. (author)
