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

    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)

    2017-03-01

    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.

    Hydro-Quebec`s successful partnership with the private sector, in particular with the consulting engineering profession, was highlighted, as an indication of the unprecedented economic activity generated by the public utility throughout its fifty year existence, and most noticeably since the 1960s, when the `Quiet Revolution` of the Lesage government set the tone for favoring Quebec consulting firms. The Corporation`s rapid growth also stimulated the development of the province`s private engineering sector, and served as the incentive for electrical equipment manufacturers, and the source of new skills and enterprises emerging from environmental concerns. Special mention was made of the economic advances made by native peoples through their involvement in land clearing, excavation, construction, and provision and transportation of supplies to remote construction sites.

    Full Text Available Fruits and nuts from the North and Northeast regions of Brazil were collected to determine the fatty acid profile of their oils. The species studied were Brazil (Bertholletia excelsa H.B.K., Mucajá (Couma rigida M., Inajá (Maximiliana maripa D., Jenipapo (Genipa Americana L., and Buriti (Mauritia flexuosa L. nuts. Fatty acid methyl esters were analyzed by gas chromatography with flame ionization detection (GC-FID. Brazil nut major fatty acid was 18:3n-3 (α-linolenic acid, and Buriti nut had approximately 23 times more 18:3n-3 than the pulp. Mucajá nut presented high content of 12:0 (lauric acid and 16:0 (palmitic acid, and Mucajá pulp showed significant levels of 18:2n-6 (linoleic acid. Considering the PUFA (polyunsaturated fatty acid sum values, almost all fruits and nuts analyzed presented very high levels of these compounds. Regarding n-6/n-3 ratio, only Brazil Nut, Buriti Nut, Inajá pulp, and Jenipapo pulp corresponded to the desired profile. These Brazilian fruits and nuts could be of potential interest due to their high nutritive value and lipid content.

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

    Since the early nineties Brazil has initiated a program of reforms in its electric sector which includes utility privatization, de-verticalization. The main objectives were to promote a market-oriented energy industry attractive to private investments. This has led to the loss of sponsorship for the public-interest programs formerly undertaken by the state utilities. In particular, of significant concern are the programs for promotion of energy efficiency, renewable energy technologies, rural electrification and environmental protection. In the midst of the privatization effort, the National Agency for Electrical Energy ANEEL was created (end of 1997). One of the tasks of the regulatory agency is to provide funds and incentives to energy conservation. In this paper we review the role of ANEEL in promoting energy efficiency investments in the context of a market-oriented sector, its limitations and prospects. [Spanish] Desde principios de los anos noventa Brasil ha iniciado un programa de reformas en su sector electrico que incluye la privatizacion del servicio electrico y la desverticalizacion. Los objetivos principales eran promover una industria de la energia orientada comercialmente de la energia electrica, atractiva a las inversiones privadas. Esto ha conducido a la perdida de patrocinio de los programas de interes publico emprendidos antes por las empresas electricas del estado. En particular, de preocupacion significativa estan los programas para la promocion del rendimiento energetico, de las tecnologias de la energia renovable, de la Electrificacion rural y de la proteccion del medio ambiente. En medio del esfuerzo de la privatizacion, la agencia nacional para la energia electrica ANEEL fue creada (finales de 1997). Una de las tareas de la agencia reguladora es proporcionar fondos e incentivos a la conservacion de energia. En este trabajo repasamos el papel de ANEEL en promover inversiones del rendimiento energetico en el contexto de un sector orientado

    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.

  1. Antioxidant and Anti-Inflammatory Activities of Unexplored Brazilian Native Fruits.

    Directory of Open Access Journals (Sweden)

    Juliana Infante

    Full Text Available Brazilian native fruits are unmatched in their variety, but a poorly explored resource for the development of food and pharmaceutical products. The aim of this study was to evaluate the phenolic composition as well as the antioxidant and anti-inflammatory activities of the extracts of leaves, seeds, and pulp of four Brazilian native fruits (Eugenia leitonii, Eugenia involucrata, Eugenia brasiliensis, and Eugenia myrcianthes. GC-MS analyses of the ethanolic extracts showed the presence of epicatechin and gallic acid as the major compounds in these fruits. Antioxidant activity was measured using synthetic DPPH free-radical scavenging, β-carotene bleaching assay, and reactive oxygen species (ROO·, O2·-, and HOCl. The fruit extracts also exhibited antioxidant effect against biologically relevant radicals such as peroxyl, superoxide, and hypochlorous acid. In general, the pulps were the fruit fractions that exhibited the lowest antioxidant activities, whereas the leaves showed the highest ones. The anti-inflammatory activity was assessed in an in vivo model using the carrageenan-induced neutrophil migration assay, which evaluates the inflammatory response in the acute phase. The pulp, seeds, and leaves of these fruits reduced the neutrophil influx by 40% to 64%. Based on these results, we suggest that the anti-inflammatory activity of these native fruits is related to the modulation of neutrophil migration, through the inhibition of cytokines, chemokines, and adhesion molecules, as well as to the antioxidant action of their ethanolic extracts in scavenging the free-radicals released by neutrophils. Therefore, these native fruits can be useful to produce food additives and functional foods.

    Manual headspace solid-phase microextraction (SPME) coupled to gas chromatography-mass spectrometry (GC-MS) was used for the qualitative analysis of the aromas of four native Brazilian fruits: cupuassu (Theobroma grandiflorum, Spreng.), cajá (Spondias lutea. L.), siriguela (Spondias purpurea, L.) and graviola (Anona reticulata, L). Industrialized pulps of these fruits were used as samples, and extractions with SPME fibers coated with polydimethylsiloxane, polyacrylate, Carbowax and Carboxen were carried out. The analytes identified included several alcohols, esters, carbonyl compounds and terpernoids. The highest amounts extracted, evaluated from the sum of peak areas, were achieved using the Carboxen fiber.

Xavante and Cherokee collected in the southern region of Brazil. The content of ascorbic acid, total carotenoids, and phenolics were determined. The profile of the phenolic compounds was assessed by high-performance liquid chromatography combined with diode array detection (HPLC-DAD. The antioxidant activity was determined using the ferric-reducing antioxidant power (FRAP assay, 2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH assay, total reactive antioxidant potential (TRAP assay, and total antioxidant reactivity (TAR assay. The Xavante blackberry and purple-fleshed pitanga showed the highest total phenolic content [816.50 mg gallic acid equivalents (GAE/100g and 799.80 mg GAE/100g, respectively]. The araçá and red-fleshed pitanga showed the highest carotenoid content (6.27 ug β-carotene/g and 5.86 ug β-carotene/g, respectively. The fruits contained several phenolic compounds such as quercetin derivatives, quercitrin, isoquercitrin, and cyanidin derivatives, which may contribute differentially to the antioxidant capacity. The highest scavenging activity in the DPPH assay was found for purple-fleshed pitanga (IC50 36.78 mg/L, blackberries [IC50 44.70 (Xavante and IC50 78.25 mg/L (Cherokee], and araçá (IC50 48.05 mg/L, which also showed the highest FRAP, followed by orange- and red-fleshed pitanga. Our results revealed that some fruits grown in southern Brazil such as purple-fleshed pitanga, blackberries, and araçá are rich sources of phenolic compounds and have great antioxidant activity.

    Full Text Available The aim of this paper was to offer econometric forecasting models to the Brazilian exported volume fruits, with a view to assisting the planning and production control, also motivated by the existence of a few published papers dealing with this issue. In this sense, it was used the ARIMA/GARCH models, considering, likewise, the occurrence of a multiplicative stochastic seasonality in these series. They were collected 300 observations of exported net weight (kg between Jan/1989 and Dec/2013 of the following fruits: pineapple, banana, orange, lemon, apple, papaya, mango, watermelon, melon and grape, which selection criteria was its importance in the exported basket fruit, because they represented 97% of total received dollars, and 99% of total volume sold in 2010, of a population about 28 kinds of exported fruits. The results showed that it was not only observed the existence of a 12 month multiplicative seasonality in banana and mango. On the other hand, they were identified two fruits groups: (1 those which are continuously exported, and (2 those which have export peaks. On the quality of the models, they were considered satisfactory for six of the ten fruits analyzed. On the volatility, it was seen a high persistence in banana and papaya series, pointing to the existence of a structural break in time series, which could be linked to the economic crises happened in the last 17 years.

    Andréa Cristina DÖRR

    2008-01-01

    Full Text Available Concerns about food safety and standards in the developed countries,particularly in Europe and the United States have made certification inevitable for worldwide fruit producers who target such export markets. The fact that certification is demanded by final consumers is increasingly making buyers, retailers and wholesalers buy certified products from the producers. For the fruitindustry in Brazil, certification has important consequences as it ensures access toexport markets. Using primary data obtained from interviews with 303 small,medium and large mango and grape producers in the regions of Juazeiro/BA andPetrolina/PE in Brazil, this paper aims at assessing the determinants of demand forcertification among mango and grape producers. Empirical analysis using a logitmodel shows that grapes farmers have higher likelihood for certification thanmango growers. The farmer’s education level and years of experience producingfruits are the major positive determinants for certification. The factors whichdecrease the chances to adopt certification are small size of the farm, nonagriculturalincome, awareness and trust type of arrangement.

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

    Directory of Open Access Journals (Sweden)

    Nobuiuki Costa Ito

    2016-03-01

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

    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.

    Brazilian native fruits have been shown as excellent sources of polyphenols which are associated with multiple biological activities including inhibition of carbohydrate-hydrolyzing enzymes, α-amylase and α-glucosidase. Postmeal blood glucose elevations and high glycemic index diets can play a major role in the development of type 2 diabetes, therefore alternative approaches to reduce postprandial hyperglycemia are of growing interest in order to reduce diabetes risk. Here we investigated the effect of six Brazilian native clarified fruit juices from Amazon, Savannah and Atlantic Forest biomes on postprandial glycemia after consumption of a carbohydrate meal. For this, 23 healthy subjects were selected to consume seven meal tests, with a 1-week interval among them, consisting in 50g white bread plus 300mL of water (control) or cambuci, cagaita, maracujá-alho, cupuaçu, camu-camu and jaboticaba clarified fruit juices. The results showed that serum glucose concentrations were significantly lower after consumption of cambuci, cagaita, camu-camu and jaboticaba juices, whereas maracujá-alho and cupuaçu juices did not decrease the amount of glucose absorbed, compared to control (pfruits may be considered as adjuvant treatment for reduction of postprandial glycemia in healthy subjects.

    Full Text Available Four different assays (the Folin-Ciocalteu, DPPH, enzymatic method, and inhibitory activity on lipid peroxidation based on radically different physicochemical principles and normally used to determine the antioxidant activity of food have been confronted and utilized to investigate the antioxidant activity of fruits originated from Brazil, with particular attention to more exotic and less-studied species (jurubeba, Solanum paniculatum; pequi, Caryocar brasiliense; pitaya, Hylocereus undatus; siriguela, Spondias purpurea; umbu, Spondias tuberosa in order to (i verify the correlations between results obtained by the different assays, with the final purpose to obtain more reliable results avoiding possible measuring-method linked mistakes and (ii individuate the more active fruit species. As expected, the different methods give different responses, depending on the specific assay reaction. Anyhow all results indicate high antioxidant properties for siriguela and jurubeba and poor values for pitaya, umbu, and pequi. Considering that no marked difference of ascorbic acid content has been detected among the different fruits, experimental data suggest that antioxidant activities of the investigated Brazilian fruits are poorly correlated with this molecule, principally depending on their total polyphenolic content.

    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.

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

  20. INTERNATIONALIZATION STRATEGIES OF THE BRAZILIAN MEAT AGRIBUSINESS SECTOR: EXPORTS OR DIRECT INVESTMENT ABROAD?

    2010-11-01

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

    The objective of this study is to evaluating the Brazilian biodiversity through physicochemical characterization and determination of antioxidant potential of three species from the Myrtaceae family, namely yellow guava (Psidium cattleyanum Sabine), guabiroba (Campomanesia xanthocarpa O. Berg), and uvaia ( Eugenia pyriformis Cambess). Guabiroba had the greater quantity of phenolic compounds (9033 mg chlorogenic acid/100 g) and vitamin C (30.58 mg/g) and showed the best TSS/TTA (total soluble solid/total titratable acid) ratio (45.12). For the ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic) method, the guabiroba (507.49 μM Trolox/g) presented the highest antioxidant potential; however, in the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, uvaia (170.26 g/g DPPH) and guabiroba (161.29 g/g DPPH) were not statistically different. The uvaia outranked the other fruits with respect to its high carotenoid (909.33 μg/g) and vitamin A (37.83 μg/g) contents, and the yellow guava, although showing a lower bioactive compound content and antioxidant activity, nevertheless presented much higher values than many traditionally consumed fruits.

    Karla de Aleluia BATISTA

    Full Text Available Abstract Seeds from endemic Brazilian fruits (Mangaba, Cagaita, Jatobá and Araticum, previously confirmed to be toxic using Artemia salina bioassay were exposed to different temperatures and heating times aiming to test inhibitory effects on toxicity, as a first approach to characterize and identify toxic compounds and their thermal stability. After treatment, water extracts from kernels were filtered and added to Artemia cultures for 24 hours after which the survival of cultures was calculated. The inhibitory effect of temperature on toxicity was significant, whereas toxins from Mangaba and Cagaita were the most labile, showing 90% Artemia survival after heating at 78 °C for 2 minutes and 10 minutes, respectively. The most resistant toxins were those found in Araticum seeds which remained active (0% Artemia survival, even after heating at 160 °C for 12 min. Response surfaces and statistical multivariate analysis showed a significant effect for both temperature and heating time (linear fit on Cagaita and Mangaba toxicity reduction, while the temperature factor was more significant in Jatobá samples. The results confirm the need to adopt safety procedures during the manufacture of industrialized derivatives for these fruits, in order to minimize toxicity risks after their consumption.

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

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

    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.

    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.

    2010-01-01

    Full Text Available Seasonality can cause severe bottlenecks in natural populations, even leading to local extinction. Large variation in resource availability may explain the bottlenecks, but the role of these variations is still poorly understood. The goal of this study was to analyze if temporal variations in the guild of drosophilids breeding in fruits of Mauritia flexuosa (Arecaceae can be explained by the shortage of this resource during the dry season. Fruits of M. flexuosa were collected over one year in a gallery forest located in the Central Brazilian Savanna. The drosophilid assemblage varied over time, with a lower density of species and of individuals in the dry season, when the percentage of colonized fruits was also smaller. These findings suggest that although the fruits were available during the dry season, they were underused. This way, the resource availability does not seem to regulate the community in the dry season.

    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 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 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.

    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.

    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.

    2002-08-01

    The occurrence of yeasts on ripe fruits and frozen pulps of pitanga (Eugenia uniflora L), mangaba (Hancornia speciosa Gom.), umbu (Spondias tuberosa Avr. Cam.), and acerola (Malpighia glaba L) was verified. The incidence of proteolytic, pectinolytic, and mycocinogenic yeasts on these communities was also determined. A total of 480 colonies was isolated and grouped in 405 different strains. These corresponded to 42 ascomycetous and 28 basidiomycetous species. Candida sorbosivorans, Pseudozyma antarctica, C. spandovensis-like, C. spandovensis, Kloeckera apis, C. parapsilosis, Rhodotorula graminis, Kluyveromyces marxianus, Cryptococcus laurentii, Metchnikowia sp (isolated only from pitanga ripe fruits), Issatchenkia occidentalis and C. krusei (isolated only from mangaba frozen pulps), were the most frequent species. The yeast communities from pitanga ripe fruits exhibited the highest frequency of species, followed by communities from acerola ripe fruits and mangaba frozen pulps. Yeast communities from frozen pulp and ripe fruits of umbu had the lowest number of species. Except the yeasts from pitanga, yeast communities from frozen pulp exhibited higher number of yeasts than ripe fruit communities. Mycocinogenic yeasts were found in all of the substrates studied except in communities from umbu ripe fruits and pitanga frozen pulps. Most of the yeasts found to produce mycocins were basidiomycetes and included P. antarctica, Cryptococcus albidus, C. bhutanensis-like, R. graminis and R. mucilaginosa-like from pitanga ripe fruits as well as black yeasts from pitanga and acerola ripe fruits. The umbu frozen pulps community had the highest frequency of proteolytic species. Yeasts able to hydrolyse casein at pH 5.0 represented 38.5% of the species isolated. Thirty-seven percent of yeast isolates were able to hydrolyse casein at pH 7.0. Pectinolytic yeasts were found in all of the communities studied, excepted for those of umbu frozen pulps.

    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.

    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 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 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.

    Consumer interest in nutritious and innovative foods encourages the development of products based on raw materials with nutraceutical potential. The health benefits provided by pomegranate have been recognized; therefore, the development of pomegranate juice may match consumer expectations regarding this goal. However, the concept has to first be accepted by the consumer. The aim of the study was to utilize a rating based conjoint analysis to investigate how Brazilian consumers perceive pomegranate juice by identifying the role of packaging attributes relevant to the consumer's intention to purchase. Five factors were considered in the study: technology used in the juice production (high hydrostatic pressure - HHP - a technology that preserves nutritional and sensory properties), antioxidants, price, preservatives, and colorant. Eight hypothetical pomegranate juice packages were created following an incomplete block design and evaluated by 150 fruit juice consumers. Three clusters were identified. The average results revealed that antioxidants were the attribute of greatest relative importance to cluster 1 (RI: 36%), followed by HHP (RI: 25%) and colorants (14%). Consumers in cluster 2 considered price as the most important attribute (RI: 41%), followed by antioxidants (RI: 21%) and HHP (RI: 18%). Cluster 3, as well as cluster 2, considered price the most important attribute (RI: 28%), followed by antioxidants (RI: 26%) and HHP (RI: 22%). The results showed that consumers valued information on the health benefits of antioxidants as well as on the technology, suggesting that both types of information may be relevant tools to increase the intention to purchase the product. The application of HHP for pomegranate juice processing was positively perceived by consumers, suggesting a potential commercial application in the Brazilian industry. Copyright © 2015 Elsevier Ltd.

    2015-09-01

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

    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.

    Local people's perceptions of cultivated and wild agrobiodiversity, as well as their management of hybridization are still understudied in Amazonia. Here we analyze domesticated treegourd (Crescentia cujete), whose versatile fruits have technological, symbolic, and medicinal uses. A wild relative (C. amazonica) of the cultivated species grows spontaneously in Amazonian flooded forests. We demonstrated, using whole chloroplast sequences and nuclear microsatellites, that the two species are strongly differentiated. Nonetheless, they hybridize readily throughout Amazonia and the proportions of admixture correlate with fruit size variation of cultivated trees. New morphotypes arise from hybridization, which are recognized by people and named as local varieties. Small hybrid fruits are used to make the important symbolic rattle (maracá), suggesting that management of hybrid trees is an ancient human practice in Amazonia. Effective conservation of Amazonian agrobiodiversity needs to incorporate this interaction between wild and cultivated populations that is managed by smallholder families. Beyond treegourd, our study clearly shows that hybridization plays an important role in tree crop phenotypic diversification and that the integration of molecular analyses and farmers' perceptions of diversity help disentangle crop domestication history.

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

  3. High levels of genetic differentiation and selfing in the Brazilian cerrado fruit tree Dipteryx alata Vog. (Fabaceae)

    Dipteryx alata is a native fruit tree species of the cerrado (Brazilian savanna) that has great economic potential because of its multiple uses. Knowledge of how the genetic variability of this species is organized within and among populations would be useful for genetic conservation and breeding programs. We used nine simple sequence repeat (SSR) primers developed for Dipteryx odorata to evaluate the genetic structure of three populations of D. alata located in central Brazil based on a leaf sample analysis from 101 adults. The outcrossing rate was evaluated using 300 open-pollinated offspring from 25 seed-trees. Pollen dispersal was measured by parentage analysis. We used spatial genetic structure (SGS) to test the minimal distance for harvesting seeds in conservation and breeding programs. Our data indicate that the populations studied had a high degree of genetic diversity and population structure, as suggested by the high level of divergence among populations . The estimated outcrossing rate suggested a mixed mating system, and the intrapopulation fixation index was influenced by SGS. We conclude that seed harvesting for genetic conservation and breeding programs requires a minimum distance between trees of 196 m to avoid collecting seeds from related seed-trees. PMID:21637609

    Full Text Available El cooperativismo agrario ha estado ligado desde sus orígenes al sector de las frutas y hortalizas, sector que arrastra desde hace años una problemática de carácter estructural, incrementada, sobretodo en el caso de la fruta, por las graves crisis de precios, la saturación de los mercados y una competencia creciente de las importaciones de terceros países. En este difícil marco, los productores deben seguir invirtiendo para mantener la competitividad y la rentabilidad de sus explotaciones, y las cooperativas, por su importancia económica, deben acometer políticas que permitan garantizar la viabilidad de dicho sector. En el presente trabajo realizamos un análisis del sector cooperativo frutícola catalán, con el fin de detectar sus puntos fuertes y débiles, así como posibles carencias y demandas. Las conclusiones muestran que las cooperativas son importantes en el sector de la fruticultura, debido sobretodo a su contribución activa a la conservación del territorio y su papel generador de empleo en numerosas zonas rurales. Pero se hace necesario la adopción de firmes decisiones y la implantación de medidas de apoyo que permitan garantizar los intereses de los socios y las necesidades de los consumidores./ The agricultural cooperatives have been linked from the origins to fruit and vegetable sector. This sector dragged on for years a structural problem, increased, especially in the case of fruit, for serious price crisis, the market saturation and increasing competition.

    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)

    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)

    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.

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

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

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

    2008-11-15

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

    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.

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

    Full Text Available This study estimated indicators of fruit and vegetable intake by Brazilian adults and examined the influence of demographic and socioeconomic variables on the consumption of these foods. We used the following indicators: daily fruit intake, daily vegetable intake, and daily consumption of five or more servings of fruits and vegetables per day. Only 41.0% of adults reported daily fruit intake, while 30.0% reported daily vegetable intake. Fruit and vegetable intake was more common in urban as compared to rural areas and increased in both genders with age, schooling, and number of household goods. We conclude that initiatives to promote fruit and vegetable consumption are necessary for the country as a whole, but special attention should be given to younger individuals, males, rural communities, and groups with less schooling and lower income.O presente estudo estimou a freqüência e a distribuição do consumo de frutas e hortaliças e analisou a influência de variáveis demográficas e sócio-econômicas na determinação do padrão de consumo desses alimentos na população adulta do Brasil. Os indicadores do consumo alimentar foram: consumo diário de frutas, de hortaliças, consumo diário de frutas e hortaliças e consumo diário de cinco ou mais porções de frutas e hortaliças. Menos da metade (41,0% dos indivíduos adultos refere o consumo diário de frutas enquanto menos de um terço (30,0% refere o consumo diário de hortaliças. O consumo de frutas e hortaliças é maior nas áreas urbanas do que nas áreas rurais e aumenta com a idade e escolaridade dos indivíduos, e com o número de bens no domicílio, em ambos os sexos. Concluímos que iniciativas de promoção do consumo de frutas e hortaliças devem atender a população como um todo, mas que especial atenção deve ser dada a indivíduos jovens, ao sexo masculino, a áreas rurais e aos estratos populacionais com insuficiente escolaridade e baixa renda.

The antiradical efficiency (AE and the kinetic parameters (Efficient concentration/EC50 and time needed to reach the steady state to EC50 concentration/TEC50 of the DPPH curve were also evaluated for comparison with the Trolox equivalent (TE values. A strong, significant and positive correlation was observed between the TE and AE values, whereas a weak and negative correlation was observed between TE and EC50, suggesting that the values of AE and TE are more useful for the determination of antiradical activity in fruits than the widely used EC50. The total phenolic content found in the fruits corresponded positively to their antioxidant activity. The high content of bioactive compounds (flavanols, anthocyanins or vitamin C relative to the apple values found in araticum, cagaita, cajuzinho, jurubeba, lobeira, magaba and tucum corresponded to the high antioxidant activity of these fruits. Flavanols and anthocyanins may be the main bioactive components in these Cerrado fruits. The daily consumption of at least seven of the twelve Cerrado fruits studied, particularly, araticum, cagaita, lobeira and tucum, may confer protection against oxidative stress, and thus, they may prevent chronic diseases and premature aging. The findings of this study should stimulate demand, consumption and cultivation of Cerrado fruits and result in sustainable development of the region where this biome dominates.

    The Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method was applied to the extraction of 14 organochlorine pesticides (OCPs) residues from commercial fruit pulps available in supermarkets in Fortaleza, Northeastern Brazil. The analyses were carried out by gas chromatography (GC), coupled to an electron-capture detector (ECD), and were confirmed by GC-tandem mass spectrometry (MS). The parameters of the analytical method, such as accuracy, precision, linear range, limits of detection and quantification, were determined for each pesticide. The results showed good linearity (R(2) ≥ 0.9916) and the overall average recoveries were considered satisfactory obtaining values between 69 and 110%, RSD of 2-15 %, except for hexachlorobenzene (HCB) in açai, acerola and guava pulp samples. The OCPs were detected in guava (α-HCH; lindane) and soursop (α, β-HCH isomers) samples. The QuEChERS method and GC-ECD were successfully used to analyze OCPs in commercially available Brazilian fruit pulps and can be applied in routine analytical laboratories.

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

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

    Full Text Available Atualmente, percebe-se uma preocupação em relação às plantas do cerrado, com grande enfoque nas fruteiras em função de suas características e usos. Apesar de ser uma área ainda pouco explorada, é crescente o número de estudos dessas espécies nativas, dentre eles, os que abrangem as técnicas de cultura de tecidos. Isso se deve uma vez que essa ferramenta biotecnológica permite a propagação de espécies com dificuldade de germinação, minimiza o problema de sementes recalcitrantes, promove a produção de mudas em larga escala, complementa bancos de germoplasma e facilita as trocas de materiais genéticos. Dessa maneira, esta revisão visa a sumarizar o histórico e panorama atual das aplicações da cultura de tecidos em fruteiras do cerrado, proporcionando sustentação para novos estudos.Currently, it's been given a huge concern to the cerrado plants, focusing on fruit trees due to their characteristics and uses. Despite being a fairly unexplored area, the number of studies on these native species has increased, especially those involving tissue culture techniques. That's because this biotechnological tool provides the propagation of species with germination difficulty, reduces problems of recalcitrant seeds, promotes large scale seedling production, complements germplasm banks and facilitates the exchange of genetic materials. Therefore, this review summarizes the history and current situation of tissue culture techniques applied to Brazilian Cerrado fruit trees, providing support to further studies.

    The Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the principal exotic pests affecting Brazilian production in the northeastern and southeastern regions of Brazil. In the south, it is has potential as a serious threat to temperate-climate fruit farms, since it is already found in urban and suburban communities in this region. We studied the biological characteristics of C. capitata populations from Pelotas-RS (temperate climate), Petrolina-PE (tropical), and Campinas-SP (subtropical). Ceratitis capitata biology was studied under controlled temperature (15, 20, 25, 30, and 35 ± 1 °C), 70 ± 10% RH, and 14:10 L:D photoperiod. The duration and survival rate of the egg, larval, and pupal stages were evaluated and the thermal requirements of these three populations were determined. The duration and survival of these developmental stages varied with temperature, with similar values for the three populations, except for some variation in the egg phase. Egg to adult developmental time for all three populations was inversely proportional to temperature; from 15 to 30 °C developmental time varied from 71.2 to 17.1, 70.2 to 17.1, and 68.5 to 16.9 days, respectively. Survival during development was affected at 15 to 30 °C, and differed significantly from survival at 20 to 25 °C. At 35 °C, immature stages did not develop. The basal temperature and degree-day requirement were similar for all immature stages except for the egg stage. The basal temperatures and thermal constants were 9.30 and 350, 8.47 and 341, and 9.60 °C and 328 degree-days for the Pelotas, Petrolina, and Campinas populations, respectively. Results suggested that survival and thermal requirements are similar for these tropical, subtropical, and temperate populations of C. capitata, and demonstrate the species' capacity to adapt to different climate conditions.

    The increasing demand for safe food without preservatives or pesticides residues has encouraged several studies on natural products with antifungal activity and low toxicity. In this study, ethanolic extracts from leaves and fruit residues (peel and seeds) of three Brazilian savanna species (Acrocomia aculeata, Campomanesia adamantium and Caryocar brasiliense) were evaluated against phytopathogenic fungi. Additionally, the most active extract was chemically characterized by ESI-MS and its oral acute toxicity was evaluated. Extracts from C. brasiliense (pequi) peel and leaves were active against Alternaria alternata, Alternaria solani and Venturia pirina with minimal inhibitory concentrations between 350 and 1000 µg/mL. When incorporated in solid media, these extracts extended the lag phase of A. alternata and A. solani and reduced the growth rate of A. solani. Pequi peel extract showed better antifungal activity and their ESI-MS analysis revealed the presence of substances widely reported as antifungal such as gallic acid, quinic acid, ellagic acid, glucogalin and corilagin. The oral acute toxicity was relatively low, being considered safe for use as a potential natural fungicide.

    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.

O consumo alimentar foi avaliado por meio de três inquéritos recordatórios de 24 horas. Em modelos de regressão logística ajustados, verificou-se que o relato de um maior número de refeições diárias estava associado à maior chance [OR (IC 95%]: [1,31 (1,05; 1,63] de consumo adequado de frutas, verduras e legumes. Por outro lado, indivíduos no terceiro tercil de consumo de ácidos graxos saturados apresentaram menor chance de consumo adequado destes alimentos [0,35 (0,21; 0,60]. Verificou-se maior tendência de consumo adequado de frutas, verduras e legumes entre indivíduos de maior idade. Os resultados sugerem que programas de intervenção mais intensivos são necessários entre indivíduos jovens e com consumo elevados de ácidos graxos saturados. Além disso, o estímulo ao maior fracionamento da dieta poderá favorecer a adesão às metas de consumo de frutas, verduras e legumes.The determination of factors associated with fruit and vegetable intake is an important tool for the development of effective intervention programs aimed at increasing the consumption of these foods.

    This study characterized the phenolic profile in siriguela, umbu-cajá and mangaba, as well in their frozen pulps (FPs). The bioaccessibility of phenolic compounds and the antioxidant activity of the FP dialysates were determined following exposure to simulated gastrointestinal conditions. The profile of phenolic compounds identified in fruit and FPs were relatively similar. After pulp processing, increases of 33.60% and 68.72% in free phenolics were observed for mangaba and umbu-cajá, respectively, whereas in siriguela, the free phenolic was reduced by 56.55%. Generally, phenolic levels decreased after exposure to simulated gastric conditions in all FPs. The bioaccessibility of phenolics varied among the evaluated FPs. The highest bioaccessibility was observed for gallic acid in the umbu-cajá FP (73.92%) and the lowest for gentisic acid in the mangaba FP (8.71%). Siriguela and umbu-cajá FP dialysates presented the highest capacity for the capture of the radical 2,2'-diphenyl-2-picrylhydrazyl hydrate, whereas the mangaba FP dialysate demonstrated the highest iron reducing capacity.

    The tucuma (Astrocaryum vulgare Mart.) is a native fruit of Amazonia, occurring mainly in the state of Para, but also found in the Brazilian northeast states and in the Brazilian central-western states. The tucuma is considered an excellent source of carotenoids with a very high concentration of {beta}-carotene, which is a precursor of vitamin A. In addition to carotenoids it is an important source of vitamin B2 (riboflavin) in fruits. This study aimed to analyze the effects of gamma radiation on the nutritional value of tucuma. The fruits were irradiated at doses of 0.5, 1.0 and 2.0 kGy irradiator with a source of cesium 137. The carotenoids were determined by spectrophotometry. The analysis of {alpha} and {beta}-carotene, thiamine, riboflavin were carried out by high performance liquid chromatography (HPLC). The {beta}-carotene accounts for 80% of total carotenoids in tucuma, and with a dose of 2 kGy, it showed the highest reduction of {beta}-carotene, about 7.5% in relation to the control. The tucuma fruit showed high levels of riboflavin from 0.183 to 0.222 {mu}g 100 g{sup -1}, and maintained stability after the gamma radiation process. However, it had low levels of thiamine from 0.050 to 0.033 {mu}g 100 g{sup -1}, and irradiated at a dose of 2 kGy showed significant reductions of thiamine, about 34% in relation to the control.

    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)

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

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

    Full Text Available A study of removal of fruits of the wild tomato, Solanum granulosoleprosum Dunal (N = 5 plants, by vertebrates was carried out in an urban environment of southern Brazil from January to May 1997 and February 1998. To verify diurnal and nocturnal removals, fruits were counted in several fruit bunches, being classified by size and color. Diurnal observations were made on plants to verify bird removal. A mist net was placed among the plants from the evening to 23:00 h to verify bat consumption. Live traps baited with S. granulosoleprosum fruits were placed on the ground among plants to verify terrestrial removers. On average it was found two ripe fruits available per bunch/day, but unripe, small, fruits were dominant (70%. Nocturnal mammals and birds-diurnal mammals partitioned fruits similarly. Bats removing fruits were Artibeus lituratus (Olfers, 1818, Pygoderma bilabiatum (Wagner, 1843 and Sturnira lilium (E. Geoffroy, 1810. Birds were Saltator similis Lafresnaye & d'Orbigny, 1837 and Thraupis sayaca (Linnaeus, 1766. Terrestrial mammals were a marsupial and three rodent species. Except for rodents, these vertebrates must be promoting the seed dispersal of S. granulosoleprosum seeds in disturbed mixed forests of southern Brazil.

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

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

Conferência Nacional de Saúde e três décadas da fundação do Centro Brasileiro de Estudos de Saúde, justifica-se uma análise sobre o projeto, processo e perspectivas da Reforma Sanitária Brasileira. Desse modo, o objetivo da presente investigação é analisar a emergência e o desenvolvimento de uma Reforma Sanitária numa formação social capitalista, seus fundamentos e características, discutindo os desafios da práxis. Partindo de quatro tipos de práxis e de mudanças em sociedades - reforma parcial, reforma geral, movimentos políticos revolucionários e revolução social total - defende-se a tese segundo a qual a Reforma Sanitária Brasileira, como fenômeno social e histórico, constitui uma reforma social. O estudo tem como hipótese que a Reforma Sanitária Brasileira, embora proposta como práxis de reforma geral e teorizada para alcançar a revolução do modo de vida, apresentaria como desfecho uma reforma parcial - setorial e institucional. Realizou-se um estudo de caso, a partir de pesquisa documental, em duas conjunturas, tendo como componente descritivo o ciclo idéia-proposta-projeto-movimento-processo e, como componente explanatório, a análise do desenvolvimento da sociedade brasileira, recorrendo ao referencial "gramsciano", particularmente às categorias de revolução passiva e transformismo. Procura-se discutir a relevância do elemento jacobino no caso de uma Reforma Democrática da Saúde, cuja radicalização da democracia contribuiria para a alteração da correlação de forças, desequilibrando o binômio conservação-mudança em benefício do segundo termo e conferindo um caráter mais progressista para a revolução passiva.Twenty years after the accomplishment of the Eighth National Health Conference and three decades after the foundation of The Brazilian Center for Health Studies, it is justified an analysis on the project, process and perspectives of Brazilian Health Sector

    This study examines the dispersal system of Guapira opposita in a tropical sandy rainforest in southeast Brazil. Guapira trees produce small fruits with a high protein content (28.4%) and low lipid content (0.3%), and the plant is primarily dispersed by birds. Mature fruits of G. opposita can fall spontaneously with the pulp intact, or be dropped by birds with bits of pulp attached. In either case, ground-dwelling ants rapidly remove the fruits to their nest (93% after 12 h). The ponerine ants Odontomachus chelifer and Pachycondyla striata are the main seed vectors among the ants, and together account for 56% (20 of 36) of the ant-fruit interactions recorded on the forest floor. Individual workers of O. chelifer and P. striata transport single fruits to their nests. Bits of pulp are fed to larvae and worker nestmates, and intact seeds are discarded outside the nest. Germination success in Guapira is higher for cleaned seeds (pulp removed) than for seeds coated by pulp. Guapira seedlings and juveniles are more frequent close to Odontomachus nests than at sites without such nests. Soil samples from Odontomachus nests had greater penetrability, and higher concentrations of P, K, and Ca than random soil samples. Field experiments suggest that the association between G. opposita seedlings and O. chelifer nests can potentially render the plant some protection against herbivores. Results indicate that fruit displacement by ponerine ants play an important role in the biology of G. opposita seeds and seedlings in the sandy forest, and illustrate the complex nature of the dispersal ecology of tropical tree species.

    Understanding the mating patterns of populations of tree species is a key component of ex situ genetic conservation. In this study, we analysed the genetic diversity, spatial genetic structure (SGS) and mating system at the hierarchical levels of fruits and individuals as well as pollen dispersal patterns in a continuous population of Theobroma cacao in Pará State, Brazil. A total of 156 individuals in a 0.56 ha plot were mapped and genotyped for nine microsatellite loci. For the mating system analyses, 50 seeds were collected from nine seed trees by sampling five fruits per tree (10 seeds per fruit). Among the 156 individuals, 127 had unique multilocus genotypes, and the remaining were clones. The population was spatially aggregated; it demonstrated a significant SGS up to 15 m that could be attributed primarily to the presence of clones. However, the short seed dispersal distance also contributed to this pattern. Population matings occurred mainly via outcrossing, but selfing was observed in some seed trees, which indicated the presence of individual variation for self-incompatibility. The matings were also correlated, especially within (r̂p(m)=0.607) rather than among the fruits (r̂p(m)=0.099), which suggested that a small number of pollen donors fertilised each fruit. The paternity analysis suggested a high proportion of pollen migration (61.3%), although within the plot, most of the pollen dispersal encompassed short distances (28 m). The determination of these novel parameters provides the fundamental information required to establish long-term ex situ conservation strategies for this important tropical species. PMID:21139632

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

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

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

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

    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)

    The petroleum sector uses a number of standardized tests to characterize raw materials and products. The development of in-company programs for assurance of measurement quality, the increasing need to demonstrate proficiency by means of certification schemes or by widely accepted metrological practices, have been promoting a more intensive use of certified reference materials, in calibration as well as in validation of measurement methods and also in order to show the qualification of the laboratories. In this paper it is presented the preparation, performed by IPT's Reference Materials Group, of the first set of reference materials specially developed considering the needs of the petroleum community. Briefly, are presented the identification of the demands from the users, selection of matrices, homogeneity tests and stability studies, and the certification of the new reference materials, which are four diesel fuel oils with certified sulfur contents and one material with flash point certified by TAG and Pensky-Martens methods. It is presented a summary of the certification process, performed by means of a combined effort of several professionals that are now working at laboratories of research institutions, refineries and other industries, universities, fuel monitoring facilities and in National Petroleum Agency.

    The aims of this study were to investigate the chemical composition and the antioxidant activity and antibacterial activity of the essential oil of Xylopia sericea fruits (OXS). The fruits of this species are popularly used for medicinal purposes, and as a condiment in food preparation. The chemical composition of OXS was analysed by GC/MS. 1,1-Diphenyl-2-picrylhydrazyl (DPPH) scavenging, β-carotene/linoleic acid bleaching and phosphomolybdenum and thiobarbituric acid-reactive substance (TBARS) assays were used to evaluate the antioxidant activity. Antibacterial activity was assessed by minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against bacterial strains of interest to human health and food spoilage. Eighty-four compounds were identified. The sesquiterpenes spathulenol (16.42%), guaiol (13.93%) and germacrene D (8.11%) were the most abundant constituents. OXS presented a significant antioxidant activity and also a high bacteriostatic effect against Staphylococcus aureus, Enterobacter cloacae, Bacillus cereus and Klebsiella pneumoniae. Those results evidenced the potential of OXS to treat human bacterial infections and as an antimicrobial ingredient for food preservation. © 2017 Royal Pharmaceutical Society.

    2016-01-01

    Full Text Available The domain of governance has largely been extolled by Nations, States or governmental and intergovernmental actors especially in upholding Nations’ sovereignty and values. While this still holds, governance complexity has been reinforced by establishment of global value chains such as in food and agriculture commodities increasingly being influenced and controlled by non-state actors in different parts of the world by both corporate and retail actors through private governance mechanisms. These mechanisms often fall short of universal standards and the resultant effect is ramified through proliferation of standards that result to state of governance that is constantly being redefined as ‘codes of colours’. This paper thus seeks for an alternate dimension based on Foucault’s governmentality theory. The quest for this overarching theory is based on its mediatory role that regulates the excesses of private interests in regulations while not prioritizing any state’s sovereignty but views governance inclusively to both the State and non-state actors; this view promotes the broader understating of global value chains in the global economy of the 21st century. The paper’s methodology is based on literature review pertinent to governance theory, value chain governance, governmentality as its key variables in light of the agrifood sector. It applies the value chain discourse and governmentatity in light of the Kenya’s Horticultural export and strategic positioning to the EU market. This paper’s novelty in light of the discourse and building on the body of knowledge and for the plausible ways and means to re-articulate value chain governance in the global economy while creating a viable alternative between the States, and Non-State actors for the benefit of both the upstream agents and downstream customers.

    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)

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

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

    Full Text Available Brazil has one of the fastest aging populations in the world and the incidence of cognitive impairment in the elderly is expected to increase exponentially. We examined the association between cognitive impairment and fruit and vegetable intake and associated factors in a low-income elderly population. A cross-sectional population-based study was carried out with 1849 individuals aged 65 or over living in São Paulo, Brazil. Cognitive function was assessed using the Community Screening Instrument for Dementia (CSI-D. Fruit and vegetable intake was assessed with a Food Frequency Questionnaire (FFQ and categorized into quartiles of intake and into total daily fruit and vegetable intake using the cut-off points for the WHO recommendations (<400 grams/day or ≥ 400 grams/day. The association between cognitive impairment and each quartile of intake, and WHO recommendation levels, was evaluated in two separate multivariate logistic models. The WHO recommendations for daily intakes ≥ 400 grams/day were significantly associated with 47% decreased prevalence of cognitive impairment. An effect modification was found in both models between cognitive impairment and "years of education and physical activity" and "years of education and blood levels of HDL" So that, having 1 or more years of education and being physically active or having 1 or more years of education and levels higher than 50 mg/dl of HDL-cholesterol strongly decreased the prevalence of cognitive impairment. In this socially deprived population with very low levels of education and physical activity and fruit and vegetable intake, those who attained WHO recommendations, had 1 year or more of education and were physically active had a significantly lower prevalence of cognitive impairment. A more comprehensive understanding of the social determinants of mental health is needed to develop effective public policies in developing countries.

O desfecho foi o consumo regular de frutas, legumes e verduras. Cerca de 1/5 da população adulta (20,9% consumia regularmente frutas, legumes e verduras. Indivíduos do sexo feminino, com 60 anos ou mais, das classes A e B, ex-fumantes e não sedentários apresentaram maior prevalência de consumo de frutas e legumes e verduras. A freqüência do consumo de frutas, legumes e verduras na população adulta residente no Município de Pelotas está aquém das recomendações atuais do Ministério da Saúde, em especial entre os homens mais jovens, de menor nível sócio-econômico e que não praticam atividade física no lazer. Políticas públicas que estimulem uma alimentação saudável são urgentemente necessárias.The study aimed to describe the frequency of fruit and vegetable intake among adults (20-69 years of age and to identify associated factors. This population-based study in 2006 included 972 adults in Pelotas, Southern Brazil. Consumption of fruits and vegetables was evaluated with three questions on habitual food intake during the year prior to the interview. The outcome variable was regular consumption of fruits and vegetables. Only one in five adults (20.9% reported consuming fruits and vegetables regularly. Female gender, age 60 years or older, higher socioeconomic status, former smoking, and physical activity were associated with the outcome variable. According to the results, fruit and vegetable intake among adults fails to meet current Ministry of Health recommendations, particularly among male, young

O tucumã é considerado como uma excelente fonte de carotenóides com maior concentração em β-caroteno, precursor da vitamina A, e além dos carotenóides, também é importante fonte de vitamina B2 (riboflavina. Por este motivo, o presente trabalho objetivou analisar os efeitos da irradiação gama sobre o valor nutricional do tucumã. Os frutos de tucumã foram irradiados com as doses de 0,5, 1,0 e 2,0 kGy num irradiador com fonte de césio 137. Foram determinados os teores de carotenóides totais por espectrofotometria. As análises de α e β-caroteno, tiamina, riboflavina foram realizadas por cromatografia líquida de alta eficiência (CLAE. Foi detectado que o β-caroteno representa 80% dos carotenóides totais e que com uma dose de 2 kGy ocorreram as maiores reduções de β-caroteno, cerca de 7,5% em relação ao controle. Os frutos também apresentaram altos teores de riboflavina de 0,183 a 0,222 μg 100 g-1 e mantiveram a estabilidade após o processo de radiação gama, no entanto, os teores de tiamina foram baixos de 0,050 a 0,033 μg 100 g-1, e os frutos irradiados na dose de 2 kGy apresentaram reduções significativas de tiamina, cerca de 34% em relação ao controle.The tucumã (Astrocaryum vulgare Mart. is a native fruit of Amazônia, occurring mainly in the state of Pará, but also found in the Brazilian northeast states and in the Brazilian central-western states.

    Abstract Fruit fly sexual behaviour is directly influenced by chemical and non-chemical cues that play important roles in reproductive isolation. The chemical profiles of pheromones and cuticular hydrocarbons (CHs) of eight fruit fly populations of the Andean, Brazilian-1 and Brazilian-3 morphotypes of the Anastrepha fraterculus cryptic species complex originating from Colombia (four populations) and Brazil (four populations) were analysed using two-dimensional gas chromatography with mass spectrometric detection. The resulting chemical diversity data were studied using principal component analyses. Andean morphotypes could be discriminated from the Brazilian-1 and Brazilian-3 morphotypes by means of male-borne pheromones and/or male and female CH profiles. The Brazilian-1 and Brazilian-3 morphotypes were found to be monophyletic. The use of chemical profiles as species- and sex-specific signatures for cryptic species separations is discussed.

    Time and quantity and quality of fruits and seeds produced are limiting factors for the recruitment of new individuals and maintenance plant species. Furthermore, species that produced fruits dispersed by animals have an important role as a source of food for different groups of animals and relay on them to dispersed their seeds. In most of the Brazilian cerrado-savanna, as in others tropical vegetations, there is a predominance of animal-dispersed species, however there is a lack of information about fruit production and its availability over time on tropical savannas. Beyond the comprehension of fruiting patterns and their relation to biotic and abiotic factors, the fruit production over time can be associated with data on fruit quality such as the fruit color and nutritional content. Those combined informations allow us to evaluate the quantity and quality of resources available in a plant community for frugivores and seed predators. For a cerrado-savanna woody community in southeastern Brazil, subjected to a marked seasonal climate, we intended to describe: (i) fruit availability over time (in number and biomass); (ii) nutritional content; and (ii) fruit color patterns over a year. We counted fortnightly the number of ripe fruits and estimated fruit biomass over a year. For the nutritional content, we evaluated the percentage of protein, lipids and carbohydrates in the pulp or aril of fleshy-fruits. We classified fruit colors in red, black, yellow, dark-red, blue and multicolored (when the fruit display is composed by a combination of two non-green colors or more). We observed a period of the highest fruit production in the wet season, with two peaks of production, and a decline in the dry season, a possible period of scarcity. As expected, fruit nutritional content followed mainly the fruiting pattern in biomass. For lipids there was a different seasonal pattern in which lipid-rich fruits were produced mainly at the end of the wet season while fruits with less

    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.

    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.

    The volatile fraction of murici, bacuri and sapodilla are here studied because of their increasing interest for consumers, abundance of production in Brazil, and the general demand for new flavors and aromas. Their volatile profiles were studied by two High Concentration Capacity Headspace techniques (HCC-HS), Headspace Solid Phase Microextraction (HS-SPME) and Headspace Sorptive Extraction (HSSE), in combination with GC-MS. Murici volatile fraction mainly contains esters (38%), carboxylic acids (19%), aldehydes (11%), alcohols (14%), others (13%) and sulfur compounds; bacuri is characterized by terpenes (41%), non-terpenic alcohols (24%), esters (15%), aldehydes (6%), and others (12%); sapodilla consists of esters (33%), alcohols (27%), terpenes (18%) and others (21%). The GC-MS component co-elution was overcome by GC×GC-qMS. The adoption of modern analysis technologies afforded to achieve a better knowledge of the volatile fraction composition of these fruit pulps by increasing substantially the number of compounds identified.

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

    Full Text Available 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.

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

    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

  4. Assessing the impact of deforestation of the Atlantic rainforest on ant-fruit interactions: a field experiment using synthetic fruits.

    Full Text Available Ants frequently interact with fleshy fruits on the ground of tropical forests. This interaction is regarded as mutualistic because seeds benefit from enhanced germination and dispersal to nutrient-rich microsites, whereas ants benefit from consuming the nutritious pulp/aril. Considering that the process of deforestation affects many attributes of the ecosystem such as species abundance and composition, and interspecific interactions, we asked whether the interaction between ants and fallen fleshy fruits in the Brazilian Atlantic forest differs between human-created fragments and undisturbed forests. We controlled diaspore type and quantity by using synthetic fruits (a plastic 'seed' covered by a lipid-rich 'pulp', which were comparable to lipid-rich fruits. Eight independent areas (four undisturbed forests, and four disturbed forest fragments were used in the field experiment, in which we recorded the attracted ant species, ant behaviour, and fruit removal distance. Fruits in undisturbed forest sites attracted a higher number of species than those in disturbed forests. Moreover, the occurrence of large, fruit-carrying ponerine ants (Pachycondyla, Odontomachus; 1.1 to 1.4 cm was higher in undisturbed forests. Large species (≥3 mm of Pheidole (Myrmicinae, also able to remove fruits, did not differ between forest types. Following these changes in species occurrence, fruit displacement was more frequent in undisturbed than in disturbed forests. Moreover, displacement distances were also greater in the undisturbed forests. Our data suggest that fallen fleshy fruits interacting with ants face different fates depending on the conservation status of the forest. Together with the severe loss of their primary dispersers in human-disturbed tropical forest sites, vertebrate-dispersed fruits may also be deprived of potential ant-derived benefits in these habitats due to shifts in the composition of interacting ant species. Our data illustrate the use of

    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)

  12. The Effects of the Global Financial Crisis on Brazilian Banking Efficiency

    2014-05-01

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

    Brazil Government is promoting palm plantations to use degraded land for biofuels. Palm production is expected to increase 35 per cent in future and there would be profuse biomass available that needs to be handled efficiently. Therefore, in this study the potential of EFB from Brazil as raw material for biorefinery was explored by compositional analysis and pretreatment conditions optimization to produce ethanol and co-products. EFB from Brazil contains significant cellulose, hemicellulose, lignin and low ash content. The optimized dilute sulfuric acid pretreatment conditions for efficient cellulose and hemicellulose separation were 160°C temperature, 1.025% v/v acid concentration, 10.5min and 20% solid loading. Under optimum pretreatment process conditions, low enzyme loading (10FPU, 20IU cellulase and glucosidase enzyme/g glucan) and 15% solid loading, 51.1g ethanol, 344.1g solid residue (65% lignin and 24.87MJ/kg LHV) and 3.7l xylose rich liquid could be produced per kg dry EFB.

    The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

  1. BRAZILIAN NEWS PORTALS CHARACTERISTICS

    2011-02-01

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

    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.

  5. Augmentative Biological Control Using Parasitoids for Fruit Fly Management in Brazil.

    Garcia, Flávio R M; Ricalde, Marcelo P

    2012-12-21

    The history of classical biological control of fruit flies in Brazil includes two reported attempts in the past 70 years. The first occurred in 1937 when an African species of parasitoid larvae (Tetrastichus giffardianus) was introduced to control the Mediterranean fruit fly, Ceratitis capitata and other tephritids. The second occurred in September 1994 when the exotic parasitoid Diachasmimorpha longicaudata, originally from Gainesville, Florida, was introduced by a Brazilian agricultural corporation (EMBRAPA) to evaluate the parasitoid's potential for the biological control of Anastrepha spp. and Ceratitis capitata. Although there are numerous native Brazilian fruit fly parasitoids, mass rearing of these native species is difficult. Thus, D. longicaudata was chosen due to its specificity for the family Tephritidae and its ease of laboratory rearing. In this paper we review the literature on Brazilian fruit fly biological control and suggest that those tactics can be used on a large scale, together creating a biological barrier to the introduction of new fruit fly populations, reducing the source of outbreaks and the risk of species spread, while decreasing the use of insecticides on fruit destined for domestic and foreign markets.

    Claro, Rafael Moreira; Monteiro, Carlos Augusto

    2010-12-01

    To analyze the influence of family income and food prices on the participation of fruits and vegetables in the food purchases of Brazilian households. Data analyzed refers to the Household Budget Survey conducted by the Instituto Brasileiro de Geografia e Estatística on a probabilistic sample of 48,470 Brazilian households between 2002 and 2003. Fruit and vegetable participation in total food purchases was expressed as a percentage of total calories purchased and as calories from fruit and vegetables adjusted for total calories purchased. A multiple regression analysis was employed to estimate elasticity coefficients, controlling for sociodemographic variables and price of other foods. Fruit and vegetable participation in total food purchases increased as the price of these foods decreased, or as income increased. A 1% decrease in the price of fruit and vegetables would increase their participation by 0.79%, whereas a 1% increase in family income would increase participation by 0.27%. The effect of income tended to be smaller among higher income strata. Reducing the price of fruit and vegetables, either by supporting their production or through fiscal measures, is a promising public policy instrument, capable of increasing the participation of these foods in the diet of the Brazilian population.

    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.

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

  13. Moroccan immigrants in the Andalusian agricultural sector

    Directory of Open Access Journals (Sweden)

    Simón Pedro Izcara Palacios

    2005-07-01

    Full Text Available In Andalucia (Spain, the absense of local labor willing to accept the wages and work conditions offered in the export farming sector, together with the growth of production of hand-harvested fruits and vegetables, has increased the farmer´s dependence upon migrant labor, principally from Morocco. Moreover, a high level of irregular labor in the agricultural sector results from the coexistence of restrictive laws with the employer´s willingness to break the law hiring cheap, flexible, non-unionized and legally defenseless labor, in order to reduce costs and increase economic benefits. At the same time, in an increasingly xenophobic atmosphere, Moroccans live in very precarious conditions which include rudimentary housing where a majority of the migrants reside in overcrowded conditions. Using qualitative methodology, this article analyzes the social situation of Moroccan migrant workers employed in agriculture in Andalucia, a region situated in the south of Spain.

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

    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.

    1991-03-01

    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.

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

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

    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.

    Full Text Available ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA. Food intake was estimated using 24-hour dietary recall (24-HDR. A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL. The Estimated Average Requirement (EAR method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years to 2,582 kcal (boy aged from14 to 17 years. Saturated fat and free sugar intake were above the maximum limit recommended ( 50.0%. Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar.

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

    Pectinases are one of the upcoming enzymes of fruit and textile industries. These enzymes break down complex polysaccharides of plant tissues into simpler molecules like galacturonic acids. The role of acidic pectinases in bringing down the cloudiness and bitterness of fruit juices is well established. Recently, there has been a good number of reports on the application of alkaline pectinases in the textile industry for the retting and degumming of fiber crops, production of good quality paper, fermentation of coffee and tea, oil extractions and treatment of pectic waste water. This review discusses various types of pectinases and their applications in the commercial sector.

    2010-09-15

    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.

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.

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

    Full Text Available This study aims to identify the interfaces and boundaries of innovation orientation of Brazilian MSEs because despite the importance of innovation for Brazilian MSEs, a thorough analysis of such initiatives in Brazil still has not actually happened. The search was developed from a quantitative approach, of applied nature and descriptive. For that a structured questionnaire was used where were interviewed 700 MSEs using a probabilistic sampling. The study offers two important conclusions. The challenges for innovation can be perceived along three dimensions: design innovation, the implementation of innovation and functional area of innovation. And the data confirms that small Brazilian companies generally have difficulties to sell their innovations. The study offers two important conclusions.

    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.

    2013-03-01

    Full Text Available Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6 t to 2008 (2.05 10(6 t was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ when compared to the "not from concentrated" juice (NFC. Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

    Carolina Santos Mello

    Full Text Available Abstract Objective To assess the feeding profile of Brazilian infants and preschool children aged 6 months to 6 years, based on the qualitative and quantitative analysis of food and nutrient intake. Data source This review analyzed studies carried out in Brazil that had food survey data on infants and preschool children. The search was limited to publications from the last 10 years included in the LILACS and MEDLINE electronic databases. Data summary The initial search identified 1480 articles, of which 1411 were excluded after the analysis of abstracts, as they were repeated or did not meet the inclusion criteria. Of the 69 articles assessed in full, 31 articles contained data on food survey and were selected. Only three studies concurrently assessed children from different Brazilian geographical regions. Of the assessed articles, eight had qualitative data, with descriptive analysis of food consumption frequency, and 23 had predominantly quantitative data, with information on energy and nutrient consumption. Conclusions The articles assessed in this review showed very heterogeneous results, making it difficult to compare findings. Overall, the feeding of infants and preschool children is characterized by low consumption of meat, fruits, and vegetables; high consumption of cow's milk and inadequate preparation of bottles; as well as early and high intake of fried foods, candies/sweets, soft drinks, and salt. These results provide aid for the development of strategies that aim to achieve better quality feeding of Brazilian infants and preschoolers.

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

    To identify dietary patterns among young adults and the relationships with socio-economic, demographic and lifestyle characteristics. Population-based, cross-sectional analysis of a cohort study. Food intake was assessed by a frequency questionnaire, and dietary patterns were identified using principal components analysis. Southern Brazil. A total of 4202 men and women aged 23 years, who participated in the 1982 Pelotas Birth Cohort Study. Five dietary patterns were identified: common Brazilian, processed food, vegetable/fruit, dairy/dessert and tubers/pasta. Subjects who had low own or maternal educational levels, low social position or who were always poor throughout life had high adherence to the common Brazilian dietary pattern. In contrast, the processed food pattern was more likely to be followed by those belonging to middle and high social position and who were never poor. Men and smokers showed high adherence to the processed food and common Brazilian dietary patterns. Vegetable/fruit pattern was more likely to be followed by women and subjects engaged in physical activity. Women also showed high adherence to the dairy/dessert pattern. Our study among young Brazilian adults has identified distinct dietary patterns that are clearly influenced by socio-economic and lifestyle characteristics, which have important policy implications in a country with marked social and economic inequalities.

    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)

    2015-12-01

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

    2015-04-01

    Full Text Available We analyze the cultural repertoires mobilized by elites to describe “Brazilian people.” We rely on survey and in-depth interview data to capture how political, bureaucratic and business elites in Brazil frame poverty and inequality. Our data suggest that elites acknowledge poverty as a structural problem for the State to solve, but remain skeptical on the odds of actual solutions, indicating fatalistic perceptions that categorize the Brazilian poor as unorganized, passive, ignorant, and irrational. Moreover, in their definition of the poor, elites draw a symbolic boundary, separating an active sector (which includes the elites and a passive one (the “people”. The paper also addresses the effects of such symbolic boundaries on the overall picture of Brazilian inequality.

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

    Solanum diploconos is an unexploited Brazilian native fruit that belongs to the same genus of important food crops, such as tomato (Solanum lycorpersicum) and potato (Solanum tuberosum). In this study, we determined, for the first time, the profile of bioactive compounds (phenolic compounds, carotenoids, ascorbic acid and tocopherols) of the freeze-dried pulp and peel of Solanum diploconos fruits, as well as of an extract obtained from the whole fruit. Additionally, the antioxidant potential of the whole fruit extract was evaluated in vitro, against reactive oxygen species (ROS) and reactive nitrogen species (RNS). Eighteen phenolic compounds were identified in the peel and pulp and 6 compounds were found in the whole fruit extract. Coumaric, ferulic and caffeic acid derivatives were revealed to be the major phenolic constituents. All-trans-β-carotene was the major carotenoid (17-38 μg g(-1), dry basis), but all-trans-lutein and 9-cis-β-carotene were also identified. The peel and pulp presented bioactive compounds with high antioxidant potential against the most physiologically relevant ROS and RNS.

    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.

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP).

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

    Science.gov (United States)

    Karstensen, J.; Peters, G.

    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. In this study we estimate the CO2

    We review recent work on realistic models that break supersymmetry dynamically and give rise to composite quarks and leptons, all in a single sector. These models have a completely natural suppression of flavor-changing neutral currents, and the hierarchy of Yukawa couplings is explained by the dimensionality of composite states. The generic signatures are unification of scalar masses with different quantum numbers at the compositeness scale, and lighter gaugino, Higgsino, and third-generation sfermion masses.

    A hypothetic Hidden Sector of the Universe, consisting of sterile fermions ("sterinos") and sterile mediating bosons ("sterons") of mass dimension 1 (not 2!) - the last described by an antisymmetric tensor field - requires to exist also a scalar isovector and scalar isoscalar in order to be able to construct electroweak invariant coupling (before spontaneously breaking its symmetry). The introduced scalar isoscalar might be a resonant source for the diphoton excess of 750 GeV, suggested recently by experiment.

    2009-01-01

    As an research example of the widely existing cooperation-competition systems, the authors present an empirical investigation on a fruit nutritive factor network. It is described by a node-weighted bipartite graph. The fruit nutritive factors are defined as the nodes, and two nodes are connected by an edge if at least one fruit contains these two nutritive factors. The fruits are defined as the collaboration acts. The node-weight Writ, which signifies the "importance degree" of each actor node, is defined as the content of a nutritive factor in a fruit. The empirical investigation results show some unique features.The node-weight distributions take so-called "shifted power law" function forms, but the act-weight distribution takes a normal form. The degree and act-degree distributions show impulsive-spectrum like forms. These observations may be helpful for the study of fruits. The network description method proposed in this article may be universal for a kind of cooperation-competition systems.

The objective of this study was to evaluate the content of bioactive compounds and total antioxidant capacities of fruits from native palms from the Brazilian Amazon. The fruits of five palm species (bacaba, buriti, inajá, pupunha, and tucumã were evaluated for levels of ascorbic acid, anthocyanins, yellow flavonoids, total carotenoids, and total extractable polyphenols, as well as the total antioxidant capacities. The fruits had high contents of extractable total polyphenols, especially bacaba and tucumã (941.56 and 158.98 mg of galic acid·100g−1, total carotenoids in the case of tucumã and buriti (7.24 and 4.67 mg·100g−1, and anthocyanins in bacaba (80.76 mg·100g−1. As for the antioxidant capacity, bacaba had the highest total antioxidant activity by the Oxygen Radical Antioxidant Capacity (ORAC (194.67 µM·Trolox·g−1, 2,2-diphenyl-1-picrylhydrazyl (DPPH (47.46 g·pulp·g−1 DPPH, and β-carotene/linoleic acid (92.17% Oxidation Inhibition (O.I methods. Bacaba phenolic profile revealed the presence of cyanidin-3-O-rutinoside and other flavonoids. The palm fruits studied can be considered good sources of bioactive compounds, some containing higher amounts than that of commonly consumed fruits. Total extractable polyphenols and anthocyanins were directly correlated to antioxidant activity in these fruits.

    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.

    Full Text Available In Brazil, few studies compare the consumption of native and exotic fruits, especially in an urban environment. The Network Theory may be useful in such studies, because it allows evaluating many bird and plant species involved in interactions. The goals of this study were: evaluate a bird frugivory interaction network in an urban environment; checking the role played by native and exotic plants in the network and comparing the consumer assemblies of these two plant groups. A literature review on bird frugivory in Brazilian urban areas was conducted, as well as an analysis to create an interaction network on a regional scale. The analysis included 15 papers with 70 bird species eating fruits from 15 plant species (6 exotic and 9 native. The exotic and native fruit consumers did not form different groups and the interaction network was significantly nested (NODF = 0.30; p < 0.01 and not modular (M = 0.36; p = 0.16. Two exotic plant species are in the generalist core of the frugivory network (Ficus microcarpa and Michelia champaca. The results point out that a relatively diversified bird group eats fruits in Brazilian urban areas in an opportunistic way, with no preference for native or exotic plants.

    Full Text Available The study aimed to examine the role of innovation in the internationalization of Brazilian companies that operate in the medium sector of Information and Communication Technology (ICT. To achieve this goal, we performed a descriptive qualitative research method used and how the study of multiple cases, which were researched in depth and Light Infocon and Dígitro. The main results of the survey revealed companies with different trajectories of internationalization, but whose innovation activities are central to the entry and operations in foreign markets. The results also showed the importance of innovative cooperative activities through alliances with universities, research institutes and other companies, and government support through funding. An additional contribution of this work was the analysis of the internationalization process of Brazilian companies innovative medium-sized sectors with high technological content, since most studies on internationalization in Brazil focuses on large industrial enterprises already established for decades in the national and sectors with low technological intensity.

    Full Text Available Trogons are pan-tropical forest birds that eat a mix of fruits and arthropods. With direct observations of wild feeding birds, I assessed the relative contribution of fruits and arthropods to the diet of three trogon species (Trogonviridis, T.surrucura, and T.rufus at Parque Estadual Intervales, southeast Brazil. Fruits and arthropods made the bulk of the food items recorded, with a tendency of frugivory increasing with body mass. The Trogon species differed in the proportion of fruits and arthropods taken, with T.viridis being the most frugivorous species (66% of feeding bouts, n = 47. The relative contribution of fruits and arthropods did not differ between the wet and dry seasons for any species. In the omnivorous gradient, T.viridis is close to the frugivorous extreme, whereas T.surrucura and T.rufus is next to the insectivorous end. Such a distinction may have important consequences for the territoriality and social behavior of these birds.Os surucuás são aves florestais pantropicais que se alimentam de frutos e artrópodes. Com observações diretas de aves forrageando na natureza, estudei a contribuição relativa de frutos e artrópodes para a dieta de três espécies de surucuás (Trogonviridis, T.surrucura, and T.rufus no Parque Estadual Intervales, sudeste do Brasil. Frutos e artrópodes foram os itens mais registrados, com uma tendência do grau de frugivoria aumentar com o aumento da massa corporal da ave. As três espécies diferiram em relação à proporção de frutos e artrópodes de que se alimentam; T.viridisfoi a espécie mais frugívora (66% dos registros, n = 47. As contribuições relativas de frutos e artrópodes para a dieta não diferiram entre as estações seca e úmida para nenhuma das três espécies. A diferença no grau de frugivoria aqui revelada pode ter conseqüências importantes para a territorialidade e organização social dos surucuás.

    Full Text Available RESUMOEste trabalho analisa o comportamento da estrutura de capital no momento de grandes investimentos e em períodos subsequentes, colocando em evidência as relações entre decisões de investimento e financiamento. Em termos empíricos, foram analisados os dados financeiros de empresas brasileiras dos setores de energia elétrica e telecomunicações que apresentaram aumento de ativo permanente igual ou superior a 75% em determinado momento entre 1996 e 2005, a fim de avaliar a evolução da estrutura de capital. A metodologia consistiu essencialmente na utilização de testes não-paramétricos de Mann-Whitney com o objetivo de comparar e analisar a estrutura de capital das empresas em momentos anteriores e posteriores à realização de grandes investimentos. Os resultados encontrados permitiram concluir que, mesmo mediante forte aumento na estrutura de ativos, a estrutura de capital das empresas do setor de energia elétrica foi afetada apenas no médio e longo prazos. Por outro lado, no setor de telecomunicações, ela não foi afetada até dois anos após o aumento realizado nos ativos permanentes. A análise de histórias específicas de empresas da amostra revelaram que suas especificidades exercem um papel crucial sobre a escolha da estrutura de capital, superando até mesmo os efeitos provocados por características setoriais. Este trabalho fornece elementos para uma melhor compreensão do tema estrutura de capital.ABSTRACTThis work analyzes the behavior of capital structures when large investments are placed as well as subsequent periods, evidencing the relationship between investment and financial decisions.

    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.

    Understanding the environmental impacts of fruit production will provide fundamental information for policy making of fruit consumption and marketing. This study aims to characterize the carbon footprints of China's fruit production and to figure out the key greenhouse gas emissions to cut with improved orchard management. Yearly input data of materials and energy in a full life cycle from material production to fruit harvest were obtained via field visits to orchards of five typical fruit types from selected areas of China. Carbon footprint (CF) was assessed with quantifying the greenhouse gas emissions associated with the individual inputs. Farm and product CFs were respectively predicted in terms of land use and of fresh fruit yield. Additionally, product CFs scaled by fruit nutrition value (vitamin C (Vc) content) and by the economic benefit from fruit production were also evaluated. The estimated farm CF ranged from 2.9 to 12.8 t CO2-eq ha(-1) across the surveyed orchards, whereas the product CF ranged from 0.07 to 0.7 kg CO2-eq kg(-1) fruit. While the mean product CFs of orange and pear were significantly lower than those of apple, banana, and peach, the nutrition-scaled CF of orange (0.5 kg CO2-eq g(-1) Vc on average) was significantly lower than others (3.0-5.9 kg CO2-eq g(-1) Vc). The income-scaled CF of orange and pear (1.20 and 1.01 kg CO2-eq USD(-1), respectively) was higher than apple, banana, and peach (0.87~0.39 kg CO2-eq USD(-1)). Among the inputs, synthetic nitrogen fertilizer contributed by over 50 % to the total greenhouse gas (GHG) emissions, varying among the fruit types. There were some tradeoffs in product CFs between fruit nutrition value and fruit growers' income. Low carbon production and consumption policy and marketing mechanism should be developed to cut down carbon emissions from fruit production sector, with balancing the nutrition value, producer's income, and climate change mitigation.

  3. 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 Growth and fruit development are conditioned by environmental factors such as solar radiation, temperature, relative humidity and rainfall, affecting phenology and metabolic processes, which are reflected in its quality and  size. Besides the variety, the age of the plant species, cultural practices, the amount of CO2, plant growth regulators and nutrition also influence this process of maturation. Moreover, the photosynthetic process occurs in immature fruits same manner as in the leaves, however, when the ripening process starts it changes because chlorophyll is degraded and other pigments intervene such as carotenoids, α-carotene and β-carotene, which contain antioxidants good for human health.

    The concept of "scientific culture" varies historically, and the examination of its continuities and transformations can help us understand the relationship between the scientific community and society. The views on the role of science in society go far beyond the advancement of a particular form of knowledge and its possible or promising fruit. They involve values, postures and practices to be disseminated and reveal expectations of social and cultural advancement. This article discusses four expressive visions of different moments in Brazilian history. The formulations of four influential authors in scientific and educational policies of the country at different times are presented and analyzed: Miguel Ozorio de Almeida, Anísio Teixeira, Maurício Rocha e Silva and Carlos Vogt.

    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.

    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)

    2016-04-01

    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.

    1998-12-01

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

    Full Text Available OBJECTIVE: Estimate the intake of phenolic compounds by the Brazilian population. METHODS: To estimate the average per capita food consumption, micro data from the National Dietary Survey and from the Household Budget Survey from 2008 to 2009 was analyzed. The phenolic content in food was estimated from the base of Phenol-Explorer. It was chosen according to compatibility and variety of food items and usual method of preparation. RESULTS: The Brazilian population consumed, on average, 460.15 mg/day of total phenolic compounds, derived mainly from beverages (48.9%, especially coffee and legumes (19.5%. Since this analysis of classes of phenolics it was possible to observe an intake of 314 mg/day of phenolic acids, 138.92 mg/day of flavonoids and 7.16 mg/ day of other kinds of phenolics. Regarding the variables studied this present study shows that those men who live in the countryside and in the northeastern region of the country had a higher consumption of phenolic compounds. Besides, consumption was higher by adults and the elderly, the medium income classes, the population with incomplete and complete primary education and those with adequate nutrition and also overweight status. CONCLUSION: The intake of phenolic compounds can be considered low, especially where consumption of fruit and vegetables is insufficient. We can conclude that coffee and black beans were the best contributors to phenolic intake.

    Full Text Available The vegetation of the Brazilian restinga (coastal woodland presents a variety of species and different characteristics, encompassing fields, fruit groves and forests on quartzarenic neosols. We hypothesised that the structure of the restinga landscape along the coast of the state of Piauí is influenced by edaphic factors and presents a pattern similar to that of other northeastern restingas. We evaluated three restingas in Piauí, using the quarter method to determine their structure. Composite soil samples were collected to determine their chemical and physical properties. Edaphic variables were correlated with plant species by canonical correspondence analysis (CCA. Phytosociological data for all three areas indicated regenerating vegetation comprising several small individuals, 82.5% of which showed a diameter at ground level < 13 cm. We also observed considerable tillering. In two of the areas, there was a predominance of Fabaceae species, such as Caesalpinia pyramidalis and Copaifera martii. Although the structural characteristics of the restingas studied were similar to those of other northeastern restingas, the former showed lower Shannon diversity indices (2.18-2.44. The CCA indicated that species distribution was influenced by edaphic factors such as pH, aluminium content and amount of organic matter. The restingas studied were similar to others along the Brazilian coast.

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

    2017-07-01

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

    2013-01-01

    The genetic divergence of 38 melon accessions from traditional agriculture of the Brazilian Northeast and three commercial hybrids were evaluated using fruit descriptors and microsatellite markers. The melon germplasm belongs to the botanic varieties cantalupensis (19), momordica (7), conomon (4), and inodorus (3), and to eight genotypes that were identified only at the species level. The fruit descriptors evaluated were: number of fruits per plant (NPF), fruit mass (FM; kg), fruit longitudinal diameter (LD; cm), fruit transversal diameter (TD; cm), shape index based on the LD/TD ratio, flesh pulp thickness, cavity thickness (CT; cm), firmness fruit pulp (N), and soluble solids (SS; °Brix). The results showed high variability for all descriptors, especially for NPF, LD, and FM. The grouping analysis based on fruit descriptors produced eight groups without taxonomic criteria. The LD (22.52%), NPF (19.70%), CT (16.13%), and SS (9.57%) characteristics were the descriptors that contributed the most to genotype dissimilarity. The 17 simple sequence repeat polymorphic markers amplified 41 alleles with an average of 2.41 alleles and three genotypes per locus. Some markers presented a high frequency for the main allele. The genetic diversity ranged from 0.07 to 0.60, the observed heterozygosity had very low values, and the mean polymorphism information content was 0.32. Molecular genetic similarity analyses clustered the accessions in 13 groups, also not following taxonomic ranks. There was no association between morphoagronomic and molecular groupings. In conclusion, there was great variability among the accessions and among and within botanic groups.

    Anthony Pereira

    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.

    Full Text Available There is concern in the South African fruit industry that a large amount of fruit and money is lost every season due to breaks in the fruit export cold chain. The possibility of a large percentage of losses in a significant sector of the economy warranted further investigation. This article attempted to highlight some of the possible problem areas in the cold chain, from the cold store to the port, by analysing historic temperature data from different fruit export supply chains of apples, pears and grapes. In addition, a trial shipment of apples was used to investigate temperature variation between different pallets in the same container. This research has added value to the South African fruit industry by identifying the need to improve operational procedures in the cold chain.

    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.

    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.

  2. Implications on the introduction of transgenics in Brazilian maize breeding programs

    2013-04-01

    Full Text Available Transgenic maize was approved in Brazil in 2008/2009. In 2012, it occupied 73% of the country maize growing area. This high adoption rate confirms studies indicating that technology use has been the major driving force in Brazilian agriculture. Maize seed market in the world has been a concentrated sector. Although, when this sector is associated with transgenesis, this concentration increases sharply. In one side, there is the idea that companies can benefit from gains of scale and complementarities to maximize their efficiency in research and development (R&D. On the other side, this concentration may allow the exercise of “market power” by dominant companies. The objective of this study is to analyze the impacts of the adoption of transgenic technology in the arrangements of maize breeding programs and seed production sector in Brazil. A critical analysis of the situation of the breeding programs that do not have this technology is made.

    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.

  4. Business, Government and Foreign Policy: Brazilian Construction Firms Abroad

    Directory of Open Access Journals (Sweden)

    Bernardo Frossard Silva Rego

    2017-04-01

    Full Text Available This article analyses the interaction between Brazilian companies and government in the context of foreign policy, observing the state's support for the internationalization of large Brazilian civil construction firms. The results show that over the years these companies had privileged access to the Federal Executive, including civil service agencies. One consequence of this system of channelling demands through the Executive was to demote the Legislative branch to a secondary role. This pattern of interaction changed following the restoration of Congress's decision-making capacity, prompting the sector to diversify its areas of influence, focusing in particular on the Congress. To expand internationally, construction firms interact with the government primarily through the Executive, specifically via the Ministry of Foreign Affairs (Itamaraty, which provides technical and diplomatic support, and the Banco Nacional de Desenvolvimento Econômico, which supplies funding. The main argument of this article is that foreign policy should be examined through the relations between state and non-state actors in a multitude of decision-making arenas, taking into consideration both domestic and international factors.

  6. Light Chiral Dark Sector

    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...

  7. Bringing back the fruit into fruit fly-bacteria interactions.

    Science.gov (United States)

    Behar, A; Jurkevitch, E; Yuval, B

    2008-03-01

    Female Mediterranean fruit flies (Ceratitis capitata) oviposit in fruits, within which the larvae develop. This development is associated with rapid deterioration of the fruit, and frequently with invasion by secondary pests. Most research on the associations between medflies and microorganisms has focused on the bacteria inhabiting the digestive system of the adult fly, while the role of the fruit in mediating, amplifying or regulating the fruit fly microflora has been largely neglected. In this study, we examine the hypothesis that the host fruit plays a role in perpetuating the fly-associated bacterial community. Using direct and cultured-based approaches, we show that this community is composed in its very large majority of diazotrophic and pectinolytic Enterobacteriaceae. Our data suggest that this fly-associated enterobacterial community is vertically transmitted from the female parent to its offspring. During oviposition, bacteria are transferred to the fruit, establish and proliferate within it, causing its decay. These results show that the host fruit is indeed a central partner in the fruit fly-bacterial interaction as these transmitted bacteria are amplified by the fruit, and subsequently maintained throughout the fly's life. This enterobacterial community may contribute to the fly's nitrogen and carbon metabolism, affecting its development and ultimately, fitness.

  8. Myxobacteria Fruiting Body Formation

    Science.gov (United States)

    Jiang, Yi

    2006-03-01

    Myxobacteria are social bacteria that swarm and glide on surfaces, and feed cooperatively. When starved, tens of thousands of cells change their movement pattern from outward spreading to inward concentration; they form aggregates that become fruiting bodies, inside which cells differentiate into nonmotile, environmentally resistant spores. Traditionally, cell aggregation has been considered to imply chemotaxis, a long-range cell interaction mediated by diffusing chemicals. However, myxobacteria aggregation is the consequence of direct cell-contact interactions. I will review our recent efforts in modeling the fruiting body formation of Myxobacteria, using lattice gas cellular automata models that are based on local cell-cell contact signaling. These models have reproduced the individual phases in Myxobacteria development such as the rippling, streaming, early aggregation and the final sporulation; the models can be unified to simulate the whole developmental process of Myxobacteria.

    Full Text Available Brazilian sparkling wines, which currently account for 30% of the national production of fine wines, have been traditionally produced in the southern region since the 1910s. The objective of the present study was to establish sparkling wine typicality via aroma characterization by comparing quantitative and descriptive techniques for the main aromatic compounds. Sparkling wines from the major producing regions of Brazil were tested by two sensory panels, followed by gas chromatography analysis that allowed elucidation of their aromatic basis. Solid-phase microextraction was used for the extraction of the compounds, followed by detection using gas chromatography (GC, olfactometry and mass spectrometry (MS. Olfactometry and gas chromatography-mass spectrometry (GC-MS identified 25 aromatic areas and 26 aromatic compounds, respectively. Fruity and floral aromas were highlighted by olfactometry. Most often, Brazilian and Italian sensory analysis panels cited pineapple and roasted or apple and fruit individual descriptors, respectively.

    Full Text Available Research studies in the area of biotechnologies in fruit growing started at the Agricultural Institute Osijek in 2006 with the establishment of the first experimental in vitro laboratory for micropropagation. The laboratory started an active research related to the Project "Biotechnological methods in fruit tree identification, selection and propagation" Project is part of program "Preservation and revitalization of grape and fruit autochthonous cultivars". The goal of this research is to determine genetic differences between autochthonous and introduced cultivars of cherry as well as cultivars and types of sour cherry, to find and optimize a method for fast recovery of clonal material. A great number of cherry cultivars and types within the population of cv. Oblacinska sour cherry exists in Croatia. A survey with the purpose of selecting autochthonous cultivars for further selection has been done in previous research. Differences have been found in a number of important agronomic traits within the populations of cv. Oblačinska sour cherry. Autochthonous cherry cultivars are suspected to be synonyms of known old cultivars which were introduced randomly and have been naturalized under a local name. Identification and description of cultivars and types of fruits is based on special visible properties which were measurable or notable. In this approach difficulties arise from the effect of non-genetic factors on expression of certain traits. Genetic-physiological problem of S allele autoincompatibility exists within cherry cultivars. Therefore it is necessary to put different cultivars in the plantation to pollinate each other. Apart form the fast and certain sort identification independent of environmental factors, biotechnological methods based on PCR enable faster virus detection compared with classical serologic methods and indexing and cover a wider range of plant pathogens including those undetectable by other methods.

    Full Text Available Abstract In this study, I tested the effect of Syagrus loefgrenii nut number on the removal intensity by rodents across seasons. Also, I assessed both S. loefgrenii fruit production, and dispersion pattern to analyze the relationship between these parameters and nut removal. Trials were performed (autumn, winter, spring, and summer, in which endocarps were placed inside trays (5, 15, and 40 endocarps in the Cerrado (Brazilian savanna. Syagrus loefgrenii exhibited clumped distribution, although its local density had no correlation with endocarp removal rate. Despite of variations, S. loefgrenii fruit production had no seasonal difference, although, high proportions of endocarps were year round removed. This mostly results from nearly complete endocarp loss in depots of 5 and 15, while the opposite occurred in those of 40. Hence, the intensity of removal consistently decreases with endocarp number, so that endocarp removal conformed to negative distance-dependence. As this palm exhibit clumped distribution and, in principle, fruit asynchronously, if, at least, a group of neighboring stems bore fruits simultaneously, an enhanced number of nuts might be available at a given site. Therefore, seeds within a dense S. loefgrenii fruit patch might experience high survival rates due to satiation of post dispersal seed predators.

    Full Text Available The effects of fruit thinning on fruit drop, leaf carbohydrates concentration, fruit carbohydrates concentration, leaf nutrient concentration and fruit quality in pummelo cultivar Thong Dee growing in Nakhon Pathom province, Thailand, were studied during January-August 2013. The results showed that 50% fruit thinning by hand at 1 month after fruit set increased percent of fruit retention throughout fruit development. At 2 month after fruit set, 50% fruit thinning gave 62% of fruit retention, which were significantly higher than no thinning (36.60%, whereas, 50% fruit thinning gave 40% of fruit retention at 6 month after fruit set, which significantly higher than no thinning (20.2%. A significant difference in leaf carbohydrate concentration was found in 3-6 month after fruit set. At 3 months after fruit set, 50% fruit thinning gave significantly higher leaf carbohydrate concentration (81.80 mg.g-1 than no thinning (73.56 mg.g-1, whereas, at 6 month after fruit set, 50% fruit thinning gave significantly higher leaf carbohydrate concentration (128.92 mg.g-1 than no thinning (102.90 mg.g-1. Although, 50% fruit thinning gave no effect on peel and pulp dry weight including peel and pulp carbohydrates concentration during fruit development. For plant nutrient analysis, 50% fruit thinning gave significantly higher leaf nitrogen (N, phosphorus (P and potassium (K concentration than no thinning during 3-6 month after fruit set. However, 50% fruit thinning had no effect on fruit weight, fruit circumstance, fruit diameter, titratable acidity (TA and total soluble solid (TSS. It was concluded that 50% fruit thinning increased percent of fruit retention and may have an effect on the accumulation of leaf carbohydrates, leaf N, leaf P and leaf K concentrations in pummelo cultivar Thong Dee.

    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.

    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.

    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.

  1. 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 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.

    Full Text Available Brazilian peach breeding programs have been established to improve peach [Prunus persica (L. Batsch] production, yield consistency, quality, and disease resistance. Every year several genotypes are selected and their traits must be assessed. This study aimed to evaluate adaptability and stability of fruit set and production of peach genotypes in a subtropical climate, using the GGE biplot methodology. The experimental design was completely randomized with three replicates (trees in a factorial arrangement of 29 × 3 for genotype and growing season, respectively. The genotypes 'Conserva 1129', 'Rubimel', 'Kampai', 'Tropic Beauty', and 'Cascata 967' had the greatest adaptability and stability for fruit set. The genotypes 'Conserva 681', 'Santa Áurea', 'Atenas', 'Kampai', 'Cascata 962', 'Tropic Beauty' and 'Cascata 967' had the greatest production adaptability and stability. The GGE-biplot methodology classified the peach tree genotypes with regard to adaptability and stability of fruit set and production.

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

    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

    Citrus is well-known for its nutrition and health-promotion values. This reputation is derived from the studies on the biological functions of phytochemicals in Citrus fruits and their derived products in the past decades. In recent years, the antioxidant activity of Citrus fruits and their roles in the prevention and treatment of various human chronic and degenerative diseases have attracted more and more attention. Citrus fruits are suggested to be a good source of dietary antioxidants. To have a better understanding of the mechanism underlying the antioxidant activity of Citrus fruits, we reviewed a study on the antioxidant activity of the phytochemicals in Citrus fruits, introduced methods for antioxidant activity evaluation, discussed the factors which influence the antioxidant activity of Citrus fruits, and summarized the underlying mechanism of action. Some suggestions for future study were also presented.

    2016-12-01

    A comprehensive review of the literature has found that the common perceptions that dried fruits are "sticky", adhere to teeth, and are detrimental to dental health on account of their sugar content are based on weak evidence. There is a lack of good quality scientific data to support restrictive advice for dried fruit intake on the basis of dental health parameters and further research is required. A number of potentially positive attributes for dental health, such as the need to chew dried fruits which encourages salivary flow, and the presence of anti-microbial compounds and of sorbitol, also require investigation to establish the extent of their effects and whether they balance against any potentially negative attributes of dried fruit. Advice on dried fruit consumption should also take account of the nutritional benefits of dried fruit, being high in fibre, low in fat and containing useful levels of micronutrients.

    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...

  1. NONLINEAR MODELS FOR DESCRIPTION OF CACAO FRUIT GROWTH WITH ASSUMPTION VIOLATIONS

    Directory of Open Access Journals (Sweden)

    JOEL AUGUSTO MUNIZ

    2017-01-01

    Full Text Available Cacao (Theobroma cacao L. is an important fruit in the Brazilian economy, which is mainly cultivated in the southern State of Bahia. The optimal stage for harvesting is a major factor for fruit quality and the knowledge on its growth curves can help, especially in identifying the ideal maturation stage for harvesting. Nonlinear regression models have been widely used for description of growth curves. However, several studies in this subject do not consider the residual analysis, the existence of a possible dependence between longitudinal observations, or the sample variance heterogeneity, compromising the modeling quality. The objective of this work was to compare the fit of nonlinear regression models, considering residual analysis and assumption violations, in the description of the cacao (clone Sial-105 fruit growth. The data evaluated were extracted from Brito and Silva (1983, who conducted the experiment in the Cacao Research Center, Ilheus, State of Bahia. The variables fruit length, diameter and volume as a function of fruit age were studied. The use of weighting and incorporation of residual dependencies was efficient, since the modeling became more consistent, improving the model fit. Considering the first-order autoregressive structure, when needed, leads to significant reduction in the residual standard deviation, making the estimates more reliable. The Logistic model was the most efficient for the description of the cacao fruit growth.

    2015-12-01

    To clarify detailed characteristics of fruit photosynthesis, possible gas exchange pathway and photosynthetic response to different environments were investigated in Satsuma mandarin (Citrus unshiu). About 300 mm(-2) stomata were present on fruit surface during young stages (∼10-30 mm diameter fruit) and each stoma increased in size until approximately 88 days after full bloom (DAFB), while the stomata collapsed steadily thereafter; more than 50% stomata deformed at 153 DAFB. The transpiration rate of the fruit appeared to match with stoma development and its intactness rather than the density. Gross photosynthetic rate of the rind increased gradually with increasing CO2 up to 500 ppm but decreased at higher concentrations, which may resemble C4 photosynthesis. In contrast, leaf photosynthesis increased constantly with CO2 increment. Although both fruit and leaf photosynthesis were accelerated by rising photosynthetic photon flux density (PPFD), fruit photosynthesis was greater under considerably lower PPFD from 13.5 to 68 μmolm(-2)s(-1). Thus, Satsuma mandarin fruit appears to incorporate CO2 through fully developed and non-collapsed stomata, and subject it to fruit photosynthesis, which may be characterized as intermediate status among C3, C4 and shade plant photosynthesis. The device of fruit photosynthesis may develop differently from its leaf to capture CO2 efficiently.

    The Brazilian energetic sector goes by a deep restructuring process, reaching all the involved agents. Thus, the Federal Government, in December 26, 1996, instituted the National Agency of Electric Energy - ANEEL, through the Law nr. 9.427, to establish the regulation of the production, transmission, distribution and commercialization of electric energy service, and to guarantee electric services. To obtain consistent data in operation of the reservoirs that subsidize the decision related to the inspection activities, regulation and mediation and to guarantee the hydrologic information associated to hydroelectric enterprises, ANEEL published in December 4, 1998, the Resolution ANEEL nr. 396 in order to establish the conditions for implementation, maintenance and operation of hydrological stations. This paper shows the beginning of the implementation of the Brazilian Monitoring System of Hydropower Dams. (author)

    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

    Although many aspects of environmental accounting methodologies in food production have already been investigated, the application of environmental indicators in the fruit sector is still rare and no consensus can be found on the preferred method. On the contrary, widely diverging approaches have been taken to several aspects of the analyses, such as data collection, handling of scaling issues, and goal and scope definition. This paper reviews studies assessing the sustainability or environmental impacts of fruit production under different conditions and identifies aspects of fruit production that are of environmental importance. Four environmental assessment methods which may be applied to assess fruit production systems are evaluated, namely Life Cycle Assessment, Ecological Footprint Analysis, Emergy Analysis and Energy Balance. In the 22 peer-reviewed journal articles and two conference articles applying one of these methods in the fruit sector that were included in this review, a total of 26 applications of environmental impact assessment methods are described. These applications differ concerning e.g. overall objective, set of environmental issues considered, definition of system boundaries and calculation algorithms. Due to the relatively high variability in study cases and approaches, it was not possible to identify any one method as being better than the others. However, remarks on methodologies and suggestions for standardisation are given and the environmental burdens of fruit systems are highlighted.

    Full Text Available This study uses retail purchase data reported by the Nielsen Homescan panel to examine the development of selected U.S. organic food sectors since the implementation of the National Organic Standards. Results show that organic market shares within the fresh fruit and vegetable sectors grew slightly in 2003–2006. Apples, bananas, carrots, and tomatoes prove to have the highest share of organic sales within their sectors. The share of organic milk sales attributed to private labels has increased from 12 to 32 percent in 2004–2007. The organic market share within the strained baby food sector almost doubled from 8 to 15 percent in 2004–2007. Findings show a demographically diverse group of consumers willing to expend their food dollars on organic foods.

    Food cues of palatable food are omnipresent, thereby simulating the intake of unhealthy snack food among children. As a consequence, this might lead to a higher intake of energy-dense snacks and less fruit and vegetables, a habit that increases the risk of developing chronic diseases. The aim of this experimental study is to examine whether playing a memory game with fruit affects fruit intake among young children. We used a randomized between-subject design with 127 children (age: 7-12 y) who played a memory-game, containing either fruit (n = 64) or non-food products (n = 63). While playing the memory-game in a separate room in school during school hours, free intake of fruit (mandarins, apples, bananas, and grapes) was measured. Afterwards, the children completed self-report measures, and length and weight were assessed. The main finding is that playing a memory-game containing fruit increases overall fruit intake (P = 0.016). Children who played the fruit version of the memory-game ate more bananas (P = 0.015) and mandarins (P = 0.036) than children who played the non-food memory-game; no effects were found for apples (P > 0.05) and grapes (P > 0.05). The findings suggest that playing a memory-game with fruit stimulates fruit intake among young children. This is an important finding because children eat insufficient fruit, according to international standards, and more traditional health interventions have limited success. Healthy eating habits of children maintain when they become adults, making it important to stimulate fruit intake among children in an enjoyable way. Nederlands Trial Register TC = 5687.

    Research suggests phytonutrients, specifically phenolic compounds, within fruit may be responsible for the putatively positive antioxidant benefits derived from fruit. Given the prominence of fruit juice in the American diet, the purpose of this research was to assess the antioxidant density of fresh fruit and 100% fruit juice for five commonly consumed fruits and juices and to compare the adequacy of 100% juice as a dietary equivalent to whole fruit in providing beneficial antioxidants. Antioxidant density was measured using an oxygen radical absorbance capacity method on six samples assayed in triplicate for each fruit (grape, apple, orange, grapefruit, pineapple), name-brand 100% juice, and store-brand 100% juice. One-way analysis of variance and Tukey's honestly significant difference or Student t test were used to assess significance (Ppineapple juice was higher than fresh grape or pineapple fruit; however, both fresh grapes and commercial grape juice contained significantly more (Pfiber with approximately 35% less sugar.

    Full Text Available The objective of this study was to explore the evolution of internal and external commercialization of Brazilian sparkling wines during the period between 1986 and 2015, giving an overview of the current situation and its market trends, and highlighting the importance of Brazil in the world scenario for sparkling wines. This research is based on quantitative data sources provided by different institutions: International Organization of Vine and Wine (OIV, Brazilian Union of Viticulture (UVIBRA, Ministry of Agriculture, Livestock and Supply (MAPA and Brazilian Agricultural Research Corporation (EMBRAPA. Brazil is a promising country for the sparkling wine market. From 1986–2015, there was an increase of 465.6% in the sales of sparkling wine in the Brazilian domestic market, especially the last ten, which accounted for an increase of 215.7%. In 1998, Brazilian sparkling wines accounted for 70.5% of sparkling wines sold in Brazil. Today, they represent 82.1%of national market, and proved to be one of the most prestigious products from Brazilian viticulture when compared, for example, to non-sparkling wines, which 79% are imported wines. Of the imported sparkling wines consumed in Brazil, six countries account for 98.5% of the market (France: 32.7%; Italy: 24.8% and Spain: 21.9%. The volume exportation of Brazilian sparkling wine has grown significantly in recent years (4,210.2%, with Paraguay, China, Uruguay, the United States, France and the United Kingdom being the major buyers. The evolution of exports shows that Brazilian sparkling wine becomes an alternative to those produced in traditional countries, such as France, Italy and Spain, due to their quality and price. There is an increase in the commercialization of sparkling wines in the Brazilian domestic market, in addition to the growing participation of Brazil in the volume of exports in the world market, placing Brazil in a leading position in the production and sale of sparkling wines.

    It is unclear how the misunderstanding that Rubus fruits (e.g., blackberries, raspberries) are high in sugar alcohol began, or when it started circulating in the United States. In reality, they contain little sugar alcohol. Numerous research groups have reported zero detectable amounts of sugar alcohol in fully ripe Rubus fruit, with the exception of three out of 82 Rubus fruit samples (cloudberry 0.01 g/100 g, red raspberry 0.03 g/100 g, and blackberry 4.8 g/100 g(∗); (∗)highly unusual as 73 other blackberry samples contained no detectable sorbitol). Past findings on simple carbohydrate composition of Rubus fruit, other commonly consumed Rosaceae fruit, and additional fruits (24 genera and species) are summarised. We are hopeful that this review will clarify Rosaceae fruit sugar alcohol concentrations and individual sugar composition; examples of non-Rosaceae fruit and prepared foods containing sugar alcohol are included for comparison. A brief summary of sugar alcohol and health will also be presented.

    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.

  4. Fruit Calcium: Transport and Physiology

    2016-04-01

    Full Text Available Calcium has well-documented roles in plant signaling, water relations and cell wall interactions. Significant research into how calcium impacts these individual processes in various tissues has been carried out; however, the influence of calcium on fruit ripening has not been thoroughly explored. Here, we review the current state of knowledge on how calcium may impact fruit development, physical traits and disease susceptibility through facilitating developmental and stress response signaling, stabilizing membranes, influencing water relations and modifying cell wall properties through cross-linking of de-esterified pectins. We explore the involvement of calcium in hormone signaling integral to ripening and the physiological mechanisms behind common disorders that have been associated with fruit calcium deficiency (e.g. blossom end rot in tomatoes or bitter pit in apples. This review works towards an improved understanding of how the many roles of calcium interact to influence fruit ripening, and proposes future research directions to fill knowledge gaps. Specifically, we focus mostly on grapes and present a model that integrates existing knowledge around these various functions of calcium in fruit, which provides a basis for understanding the physiological impacts of sub-optimal calcium nutrition in grapes. Calcium accumulation and distribution in fruit is shown to be highly dependent on water delivery and cell wall interactions in the apoplasm. Localized calcium deficiencies observed in particular species or varieties can result from differences in xylem morphology, fruit water relations and pectin composition, and can cause leaky membranes, irregular cell wall softening, impaired hormonal signaling and aberrant fruit development. We propose that the role of apoplasmic calcium-pectin crosslinking, particularly in the xylem, is an understudied area that may have a key influence on fruit water relations. Furthermore, we believe that improved

    Gibberellins (GAs) have been shown by others to be required for normal development of pea fruit. Whether the pericarp of the developing pea fruit produces GAs in situ is not known. To determine if the pericarp has the capacity to produce GAs during fruit growth, the metabolism of the first two committed GAs in the biosynthetic pathway, ({sup 14}C)GA{sub 12}-aldehyde and ({sup 14}C)GA{sub 12} was examined in tissue obtained from pollinated, parthenocarpic, and control fruit over 4 days from treatment. ({sup 14}C)GA{sub 12}-aldehyde was converted primarily to conjugates, including ({sup 14}C)GA{sub 12}-aldehyde conjugate. ({sup 14}C)GA{sub 12} was converted to ({sup 14}C)GA{sub 53} in all tissue, but by day 4 only tissue from pollinated or parthenocarpic fruits showed sustained formation of ({sup 14}C)GA{sub 53}. When ({sup 14}C)GA{sub 12} is applied to 4-day-old fruits attached to the plants, the major product obtained after 24 hours is ({sup 14}C)GA{sub 20} (as identified by GC-MS). No transport to the developing seed was observed. These results indicate that the elongating fruit tissue has the capacity to produce GAs.

    Directory of Open Access Journals (Sweden)

    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.

    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.

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.

    Full Text Available Spatial information describes the physical location of either people or objects, and the measured relationships between them. In this article we offer the view that greater utilisation of spatial information and its related technology, as part of a broader redesign of the architecture of health information at local and national levels, could assist and speed up the process of health reform, which is taking place across the globe in richer and poorer countries alike.In making this point, we describe the impetus for health sector reform, recent developments in spatial information and analytics, and current Australasian spatial health research. We highlight examples of uptake of spatial information by the health sector, as well as missed opportunities. Our recommendations to spatially enable the health sector are applicable to high and low-resource settings.

    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.

  17. Acausality from a Dark Sector

    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.

  18. Regulation of the power sector

    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...

    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.

    Full Text Available ABSTRACT The agronomical responses of Chardonnay, a variety indicated for sparkling wine production, is influenced by the vineyard management and the edaphoclimatic conditions of the region. The objective of this study was to evaluate the effects of two pruning types (Royat and double Guyot on vegetative and reproductive development of Chardonnay vine growing at high altitude in the Brazilian southeastern region. The experiment was carried out in a commercial vineyard located at 1,280 m of altitude in Divinolândia, São Paulo State, Brazil. The Chardonnay vines (clone 96, grafted onto 1103 Paulsen rootstock and trained in a vertical shoot positioning trellis system, were assessed. Vegetative vigor, bud fruitfulness, production and physicochemical composition of grapes were evaluated during 2014 and 2015 growing seasons. The Royat pruning induced higher vegetative vigor and increased the bud fruitfulness, the cluster number and the productivity of Chardonnay vine when compared to Guyot pruning. Even though the increase on yield was observed, there was no effect of pruning type on grape final quality. Therefore, the choice of pruning method in function of variety genetic characteristics and their interaction with environment can optimize the vineyard profitability. In the Brazilian southeast, the Royat system is the most suitable one to grow Chardonnay for sparkling wines production.

    The objective was to identify the cost of meeting the Brazilian National Dietary Guidelines and analyze the impact on family budget. Data from the Brazilian Household Budget Survey for 2008 were used. Food purchases were recorded for seven days in 55,970 households. A subset of low-income families (≤ BRL 415.00 per capita/month and ≤ US$ 1.00 per capita/day) was used for the analysis. We estimated per capita calorie availability, total food expenditures, and food prices aggregated in 8 food groups based on the Brazilian Guidelines. Each food group's share in total calories was estimated and compared to the recommendations. Actual purchases exceeded the recommendations for beans, oils/fats, sweets, and meat/eggs, and fell short for fruits, vegetables, dairy products, and grains. Meeting the recommendations would increase food expenditures by 58% among individuals with per capita income ≤ US$ 1.00/day and by 39% for those with per capita income ≤ BRL 415.00. Adoption of the recommendations would require 145% of total income. Meeting current recommendations would demand an increase in income or a policy to reduce food prices.

    Next years world and Brazilian ethanol demand will be grow of an eminent way, so players of economical activity must take a position. We know that energy and agriculture sectors that will feel more quickly the changes of the expansion due to ethanol production. Adjustments must come in both sectors, either for the imperious necessity of land losses by agricultural commodities or market losses of gasoline in the transportation sector. This paper presents an evaluation about the changes and challengers that will come in the energy and agricultural sectors as a consequence of voluminous Brazilian and American production of ethanol foreseen for the next years. In our analyse exogenous and endogenous factors are evaluated taking into account correlations between demand of the ethanol and the gasoline and, between the expansion cane crops and other cultures.

  15. Futebol mulato: racial constructs in Brazilian football

    Directory of Open Access Journals (Sweden)

    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.

    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. In this Institution special attention was due against discrimination of HIV-infected patients, to diagnosis, to anonymous and sigilous tests, to medical and psychological assistance, to myocardium involvement, to the virologic study of the

    Full Text Available This article extends the current research on innovation by investigating the relationship between innovative capabilities and export firms’ overall performance. From the perspectives of the resource-based view (RBV and dynamic capability, we examine the differential and interactive effects of exploration and exploitation capabilities in product innovation for external markets and overall performance (direct and mediated by a new product. In addition, we test the moderating effect of market dynamism and the controlling effect of firm size on these relationships. Hence, the main contribution of this article is developing and empirically testing an original model, by combining these constructs that address new relationships, in an emerging country. This model was tested with data from 498 Brazilian export firms, distributed throughout all Brazilian manufacturing sectors, by firm size, and in states. The analysis was made with application of the structural equation modeling (SEM. As a result, we found support for the assumptions that exploitation capabilities influence product innovation and overall performance, whereas exploration capabilities and their interaction to exploitation capabilities influence overall performance, but not product innovation. Additionally, the relationship between exploitation capabilities and overall performance is mediated by product innovation. Unlike hypothesized, market dynamism does not moderate the relationship between product innovation and overall performance. Furthermore, firm size works as a controlling variable in the relationships analyzed. Regarding the implications for theory, this study contributes to grasp that exploitation capabilities influences a firm’s overall performance, both directly and indirectly (via product innovation, and highlights the various direct and mediatory effects of innovation on overall performance. These insights show the importance of considering the role of mediating and

    Data for two birth cohorts from two Brazilian municipalities, Ribeirão Preto in 1994 and São Luís in 1997/1998, were used to identify and compare factors associated with inadequate utilization of prenatal care and to identify factors capable of explaining the differences observed between the two cities. Prenatal care was defined as adequate or inadequate according to the recommendations of the Brazilian Ministry of Health. The chi-square test and Poisson regression were used to compare differences in the inadequacy of prenatal care utilization. The percentage of inadequacy was higher in São Luís (34.6%) than in Ribeirão Preto (16.9%). Practically the same variables were associated with inadequacy in both cities. Puerperae with lower educational level, without a companion or cohabiting, who delivered in public health units, younger than 20 years, multiparae and smokers, with low family income presented higher percentages of inadequate prenatal care utilization. However, the effects of some variables differed between the two cities. The risk for inadequate use of prenatal care was higher for women attended in the public health sector in São Luís and for cohabiting women in Ribeirão Preto. The effect of the remaining factors studied did not differ between cities. The category of admission accounted for 57.0% of the difference in the inadequate use of prenatal care between cities and marital status accounted for 45.3% of the difference. Even after adjustment for all variables, part of the difference in the inadequacy of prenatal care utilization remained unexplained.

    To describe the study design, operational strategies, procedures, and baseline characteristics of the Brazilian Amazon Region Eye Survey (BARES), a population-based survey of the prevalence and causes of distance and near visual impairment and blindness in older adults residing in the city of Parintins. Cluster sampling, based on geographically defined census sectors, was used for cross-sectional random sampling of persons 45 years and older from urban and rural areas. Subjects were enumerated through a door-to-door survey and invited for measurement of uncorrected, presenting and best-corrected visual acuity and an ocular examination. Of 9931 residents (5878 urban and 4053 rural), 2384 individuals (1410 urban and 974 rural) were eligible and 2041 (1180 urban and 861 rural) had a clinical examination (response rate 85.6%). The majority of participants were female (1041, 51.0%); the average age was 59.9 ± 11.1 years (60.2 ± 11.2 years for urban and 59.4 ± 11.1 years for rural); 1360 (66.6%) had primary schooling or less (58.1% in urban and 78.4% in rural) and 57.8% were resident in urban areas. The age distribution between sexes was similar (p = 0.178). Both sex and age distributions of the sample were comparable to that of the Brazilian Amazon Region population. The BARES cohort will provide information about the prevalence and causes of near and distance vision in this underprivileged and remote population in Brazil.

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.

    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.

  9. 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.

    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.

    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.

    While wine is traditionally viewed as a product typical of European and Mediterranean wine producing countries, in recent decades vineyards have developed in all continents. Consequently, wines have been classified as coming from the Old World (traditional European and Middle Eastern producers), and New World (countries who developed their tradition in wine making more recently). Apart from individual taste, the marketing strategy adopted in these two origins clearly differentiates: based lar...

  17. Ergonomic analysis of the use of open-plan offices in Brazilian public sector offices.

    Costa, Ana Paula Lima; Villarouco, Vilma

    2012-01-01

    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 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.

    Full Text Available OBJECTIVE: This study aimed to assess diet quality among adolescents with HIV/AIDS. METHOD: A cross-sectional study was conducted involving patients with HIV/AIDS treated in a referral hospital in Sao Paulo, Brazil. Eighty-eight adolescents (10-19 years of age participated in the study. Information on disease history and use of medication were obtained from medical records. The participants responded to two 24-hour diet recalls. Diet quality was assessed by means of the Healthy Eating Index-2005 (HEI-2005 adapted to the Brazilian population. Pearson's correlation coefficients were calculated. Mean HEI-2005 scores were compared according to the independent variables using either the Student's t-test or the Mann-Whitney test. RESULTS: The mean HEI-2005 score was 51.90 (SE = 0.90. The components with the lowest means were whole grains and sodium. Components with highest means were total grains and oils. No correlations were found between the independent variables and HEI score. Adolescents living in foster homes had higher means for total fruit and lower means for meat and beans in comparison to adolescents living with their families. Girls had higher means for milk and lower means for calories from solid fats, alcoholic beverages, and added sugars in comparison to boys. CONCLUSIONS: Adolescents with HIV/AIDS exhibited a similar eating pattern to that of adolescents in the general population: high consumption of added sugar, saturated fat, and sodium, and insufficient ingestion of whole grains and fruits. Special attention should be paid to the diet of adolescents with HIV/AIDS, who are at greater risk of developing cardiovascular and other chronic diseases.

  1. Brazilian Coffee Production as Function of Global Warming.

    According to the Brazilian Government the actual area of coffee production in the country is close to 2.25 million hectares. The sector involves 290.000 of farmers with a production of 44 million of 60 Kg bags in 2015. The Arabica Coffee specie is cultivated in the country where the climate condition are characterized by a year mean temperatures between 18°C and 22°C. Temperatures higher than 33°C can cause abortion of flowers during the spring season and reduce the production while lower than 18°C can be affected by frost during winter when the minimum temperature can be lower than 2°C in the shelter. For a better quality of the final product the winter, between July and August, must be dry with rainfall lower than 50 mm/month. The Ministry of Agriculture defines those conditions for the Official Coffee Climatic Risk Zoning. In 2002, a partnership with the British Embassy and 2 Brazilian institutions, i. e. the State University of Campinas - UNICAMP and the Brazilian Agricultural Research Corporation - Embrapa, published the study "Global Warming and the New Geography of Agricultural Production in Brazil" (Pinto and Assad, 2002). This study was based on the PRECIS/Hadley Centre Regional Climate Model future projections. The crop simulations indicated a decrease in the grain production due to temperature rise. Later in 2012, a new study was developed in cooperation with the World Bank to evaluate the future of nine main commodities in Brazil under climate change, including the Arabica coffee. The worst scenario considering any mitigation and adaptation action indicated that the two most affected crops would be the soybean and coffee, with a reduction of 22% and 6.7 % in the yield respectively. Field surveys to evaluate the historical spatial dynamic and migration of Arabica coffee cultivated areas confirmed the results of the previous studies and indicated a recent increase in the search for cooler altitude areas to plant coffee.

  6. The replacement of payroll tax by a tax on revenues: A study of sectorial impacts on the Brazilian economy

    Directory of Open Access Journals (Sweden)

    Wilton Bernardino da Silva

    2015-01-01

    Full Text Available A topic of current research in discussion about the Brazilian economy is the exemption from payroll taxes, which aims to stimulate competitiveness of the firms, boosting economic growth. This topic was introduced in Brazil by new laws that proposed replacing the payroll tax with a new tax on revenues. The payroll tax rate of 20% was replaced by a tax rate of 1% or 2% on revenue. This change has been applied primarily in labor-intensive economic sectors. In this paper, a neoclassical model was used to evaluate some sectoral impacts of these tax changes. The results show positive effects of this reform, among them, the increase in aggregate consumption and capital stock. Employment also grows in the labor-intensive sector. However, under a government revenue neutral scenario, these effects are almost completely lost, which shows some evidence about the low efficiency of these reforms.

Internal economy: The service sector has the biggest weight of 67.7% in PIB frame followed by the industrial one with a share of 25.8%. The agriculture represents only 6.5% of PIB. The manpower owned by Brazil is around 95 million (from a total population of about 195 million inhabitants shared as follows: 20% in agriculture, 14% in industry and 66% in service sector. Due to the scientific and technological development of Brazil, this country is very attractive for the foreign investors, the average being somewhere around 2- billion $ comparing to the average value of 2 billion $ according to the years 1990 – 2000. External economy: Lula administration used the solid increase of the global demand in the last years in order to decrease the external duty, to smooth the profile of the date of payment of the debt and to improve the interest dynamics and the currency. The massive capital influxes have led to the increase of the currency reserves at 245.8 billion $ (the equivalent of the importers’ value for more than a year. However, the current account deficit will reach about 3.5% of PIB, and even if the foreign direct investments could not cover this deficit, we do not see any problems at horizon in its financing. Fiscal sector: even if the government has managed to maintain most of the macro-economical indicators in positive values, the lack of certain tools of limiting the public expenditures was translated by a continuous increase and a damage of the report between the public debt and PIB across the last years.

    2016-01-01

    Full Text Available The Brazilian wine industry has been facing obstacles such as competition and high tax rates. Innovation is an alternative towards this scenario being it a major factor for any company's survival and growth in the market. Besides this, technological advances and access to information provide consumers with a larger number of choices and knowledge for an informed decision making. Despite differentiation efforts consumers did not obtain satisfaction. Customer interaction provides another way to generate innovation from its involvement in the production process (co-creation of value. The research was held in an awarded winery located in Bento Gonçalves (Brazil with the objective of understanding how the process of value co-creation between Brazilian award-winning wineries and consumers influences innovation generation. It is an exploratory and qualitative study collected through in-depth interviews with a semi-structured script. The winery identifies beneficial effects in the production process resulting from interactions because it narrows the bond with the consumer creating a better understanding of the consumers as well as develop a more tailored offer regarding value. The innovations generated based on co-creation can be taken as an alternative to imposed barriers in the current Brazilian wine sector.

    Dietary fiber (DF) contributes to the energy value of foods and including it in the calculation of total food energy has been recommended for food composition databases. The present study aimed to investigate the impact of including energy provided by the DF fermentation in the calculation of food energy. Total energy values of 1753 foods from the Brazilian Food Composition Database were calculated with or without the inclusion of DF energy. The energy values were compared, through the use of percentage difference (D%), in individual foods and in daily menus. Appreciable energy D% (⩾10) was observed in 321 foods, mainly in the group of vegetables, legumes and fruits. However, in the Brazilian typical menus containing foods from all groups, only D%energy may cause slight variations in total energy; on the other hand, there is appreciable energy D% for certain foods, when individually considered.

    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.

    Badiani, R; Becker, J

    1995-11-01

    In response to an alarming rise in human immunodeficiency virus (HIV) infection among Brazilian women during the early 1990s, the Sociedade Civil Bem-Estar Familiar no Brazil (BEMFAM) developed a project that integrates HIV prevention with clinical services, community-based prevention activities, and sexually transmitted disease diagnosis and treatment. Preliminary interviews with clinic clients revealed that women's fears they would be considered unfaithful were impeding their ability to suggest condom use to their sexual partners. Condom use within a relationship was considered appropriate only for pregnancy prevention. To facilitate dialogue about sexual health, BEMFAM developed a women's group intervention project. All women who attend a BEMFAM clinic are invited to participate in a one-hour group discussion before receiving medical services. Novela-style booklets with stories and characters women can relate to their own lives are used to stimulate discussion. Participants learn to use condoms correctly by putting them on a penis model and anticipate situations in which they would be able to negotiate condom use. The group setting enables women to gain confidence and practice assertiveness in a non-threatening, supportive environment. Their identification with other women's stories empowers women to take control of their health and sexual lives. Between October 1994 and July 1995, 3464 women participated in group discussions organized by BEMFAM and 40,688 condoms were distributed; 18% of these women returned to the clinic for additional condoms.

    At the end of 2011 Brazil had a total installed capacity of ca. 116,000 MW of electricity generation connected to its national interconnected system, in which more than 70% is from Hydropower. According to the latest expansion plan published by the National Energetic Research entity (EPE - Empresa de Pesquisa Energetica) in December 2011, the total energy demand of Brazil shall increase over 60% within the next 10 years. From this forecasted demand 67% will be still covered by Hydropower, which will, however, lose a significant share to other renewable sources like Wind, Biomass and Small Hydro. The forecast of EPE predicts the expansion of renewable energy sources in the overall electric energy supply matrix from the current 8% to 16%. Solely the participation of wind power shall increase from less than 1% to about 7% by the end of 2020. The forecast of the wind power expansion is supported by the Brazilian Wind Energy Atlas (Atlas Eolico Brasileiro) published by Eletrobras in 2011, which indicates an overall wind energy potential of 143 GW.

    Full Text Available A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah soils located in Passos, Luminárias, and Arcos municipalities (Minas Gerais State, Brazil. The soils were characterised for chemical and microbiological analysis. The microbial analysis led to the identification of nine genera (Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis, Microbacterium, Frankia, Leifsonia, Nakamurella, and Kitasatospora and 92 distinct species in both seasons studied (rainy and dry. The rainy season produced a high microbial population of all the aforementioned genera. The pH values of the soil samples from the Passos, Luminárias, and Arcos regions varied from 4.1 to 5.5. There were no significant differences in the concentrations of phosphorus, magnesium, and organic matter in the soils among the studied areas. Samples from the Arcos area contained large amounts of aluminium in the rainy season and both hydrogen and aluminium in the rainy and dry seasons. The Actinobacteria population seemed to be unaffected by the high levels of aluminium in the soil. Studies are being conducted to produce bioactive compounds from Actinobacteria fermentations on different substrates. The present data suggest that the number and diversity of Actinobacteria spp. in tropical soils represent a vast unexplored resource for the biotechnology of bioactives production.
