Análise das emissões gasosas de um veículo flex funcionando com diferentes combustíveis

Efforts in research and development of new technologies to reduce emission levels of pollutant gases in the atmosphere has intensified in the last decades. In this context, it can be highlighted the modern systems of electronic engine management, new automotive catalysts and the use of renewable fuels which contributes to reduce the environmental impact. The purpose of this study was a comparative analysis of gas emissions from a automotive vehicle, operating with different fuels: natural gas, AEHC or gasoline. To execute the experimental tests, a flex vehicle was installed on a chassis dynamometer equipped with a gas analyzer and other complementary accessories according to the standard guidelines of emission and security procedures. Tests were performed according to NBR 6601 and NBR 7024, which define the urban and road driving cycle, respectively. Besides the analysis of exhaust gases in the discharge tube, before and after the catalyst, using the suction probe of the gas analyzer to simulate the vehicle in urban and road traffic, were performed tests of fuel characterization. Final results were conclusive in indicating leaded gasoline as the fuel which most contributed with pollutant emissions in atmosphere and the usual gasoline being the fuel which less contributed with pollutant emissions in atmosphere

Remoção de ruídos sísmicos utilizando transformada de wavelet 1D e 2D com software em desenvolvimento

In the Hydrocarbon exploration activities, the great enigma is the location of the deposits. Great efforts are undertaken in an attempt to better identify them, locate them and at the same time, enhance cost-effectiveness relationship of extraction of oil. Seismic methods are the most widely used because they are indirect, i.e., probing the subsurface layers without invading them. Seismogram is the representation of the Earth s interior and its structures through a conveniently disposed arrangement of the data obtained by seismic reflection. A major problem in this representation is the intensity and variety of present noise in the seismogram, as the surface bearing noise that contaminates the relevant signals, and may mask the desired information, brought by waves scattered in deeper regions of the geological layers. It was developed a tool to suppress these noises based on wavelet transform 1D and 2D. The Java language program makes the separation of seismic images considering the directions (horizontal, vertical, mixed or local) and bands of wavelengths that form these images, using the Daubechies Wavelets, Auto-resolution and Tensor Product of wavelet bases. Besides, it was developed the option in a single image, using the tensor product of two-dimensional wavelets or one-wavelet tensor product by identities. In the latter case, we have the wavelet decomposition in a two dimensional signal in a single direction. This decomposition has allowed to lengthen a certain direction the two-dimensional Wavelets, correcting the effects of scales by applying Auto-resolutions. In other words, it has been improved the treatment of a seismic image using 1D wavelet and 2D wavelet at different stages of Auto-resolution. It was also implemented improvements in the display of images associated with breakdowns in each Auto-resolution, facilitating the choices of images with the signals of interest for image reconstruction without noise. The program was tested with real data and the results were good

Uma metodologia para a análise do desempenho sustentável dos postos de revenda de combustível na cidade de Natal/RN, com o uso de data envelopment analysis-DEA

The increasing use of fossil fuels in line with cities demographic explosion carries out to huge environmental impact in society. For mitigate these social impacts, regulatory requirements have positively influenced the environmental consciousness of society, as well as, the strategic behavior of businesses. Along with this environmental awareness, the regulatory organs have conquered and formulated new laws to control potentially polluting activities, mostly in the gas stations sector. Seeking for increasing market competitiveness, this sector needs to quickly respond to internal and external pressures, adapting to the new standards required in a strategic way to get the Green Badge . Gas stations have incorporated new strategies to attract and retain new customers whom present increasingly social demand. In the social dimension, these projects help the local economy by generating jobs and income distribution. In this survey, the present research aims to align the social, economic and environmental dimensions to set the sustainable performance indicators at Gas Stations sector in the city of Natal/RN. The Sustainable Balanced Scorecard (SBSC) framework was create with a set of indicators for mapping the production process of gas stations. This mapping aimed at identifying operational inefficiencies through multidimensional indicators. To carry out this research, was developed a system for evaluating the sustainability performance with application of Data Envelopment Analysis (DEA) through a quantitative method approach to detect system s efficiency level. In order to understand the systemic complexity, sub organizational processes were analyzed by the technique Network Data Envelopment Analysis (NDEA) figuring their micro activities to identify and diagnose the real causes of overall inefficiency. The sample size comprised 33 Gas stations and the conceptual model included 15 indicators distributed in the three dimensions of sustainability: social, environmental and economic. These three dimensions were measured by means of classical models DEA-CCR input oriented. To unify performance score of individual dimensions, was designed a unique grouping index based upon two means: arithmetic and weighted. After this, another analysis was performed to measure the four perspectives of SBSC: learning and growth, internal processes, customers, and financial, unifying, by averaging the performance scores. NDEA results showed that no company was assessed with excellence in sustainability performance. Some NDEA higher efficiency Gas Stations proved to be inefficient under certain perspectives of SBSC. In the sequence, a comparative sustainable performance and assessment analyzes among the gas station was done, enabling entrepreneurs evaluate their performance in the market competitors. Diagnoses were also obtained to support the decision making of entrepreneurs in improving the management of organizational resources and promote guidelines the regulators. Finally, the average index of sustainable performance was 69.42%, representing the efforts of the environmental suitability of the Gas station. This results point out a significant awareness of this segment, but it still needs further action to enhance sustainability in the long term

Mortalidade materna no estado da Paraíba, 2000 a 2004

Esta tese articulou as áreas do conhecimento da Epidemiologia, Saúde Pública, Demografia e Estatística. Para esta investigação, traçaram-se duas estratégias: por um lado, buscou-se relatar a trajetória dos direitos femininos em saúde no Brasil a partir do período pós-guerra até os dias atuais; por outro lado, objetivou-se analisar diferenciais da morte materna e suas associações com variáveis sociodemográficas das mulheres residentes no estado da Paraíba no período de 2000 a 2004. As explorações decorrentes destes objetivos resultaram na produção de três abordagens. Na primeira, procedeu-se a um olhar retrospectivo sobre as políticas de saúde da mulher no país e seus desdobramentos regionais, enfocando a saúde materna. A análise permitiu reconhecer que, apesar de todas as conquistas adquiridas pelas mulheres desde os anos 80, a população feminina brasileira, em particular a paraibana, ainda carece de melhorias nas condições de saúde, sendo esta situação retratada pelo elevado número de mortes maternas ocorridas nos últimos anos. Também se buscou retratar os esforços dos sistemas oficiais na luta pela melhoria da qualidade dos dados reconhecida, na agenda nacional, como sendo ainda uma grande preocupação atual. Na segunda, o objetivo foi identificar o poder associativo entre a raça das mulheres residentes no estado da Paraíba e algumas variáveis sociodemográficas. Os resultados mostraram que houve indícios significativos de que as mulheres não brancas da Paraíba tiveram maiores chances de morrer que as brancas com baixa escolaridade e por morte obstétrica direta. Na terceira, centrou-se no tipo de óbito materno, cujo objetivo consistiu em analisar associações entre o tipo de óbito materno das mulheres paraibanas e as variáveis: grupo etário, escolaridade e raça, no período de 2000 a 2004. Os testes estatísticos realizados apontaram que a mulher paraibana teve cinco vezes mais chances de morrer por morte obstétrica direta ou indireta na faixa etária abaixo dos 20 anos e acima dos 34 em relação a faixa etária entre 20-34 anos

Análise do estado da arte dos aspectos diagnóticos, periciais e jurisprudenciais das LER/DORT no contexto previdenciário das doenças do trabalho no Brasil

Objetivo: analisar o estado da arte dos aspectos diagnósticos, periciais e jurisprudenciais das LER/DORT (Lesões por Esforços Repetitivos / Distúrbios Osteomusculares Relacionados ao Trabalho) no Brasil. Materiais e Método: trata-se de pesquisa descritiva, de natureza qualitativa, com formato documental, utilizando-se a técnica de análise de conteúdo. A avaliação evolutiva da legislação previdenciária relacionada as LER/DORT foi realizada através da pesquisa no banco de dados disponibilizado pelo Governo Federal e mediante a consulta ao DATAPREV/Sislex. A avaliação dos aspectos diagnósticos foi instrumentalizada através, principalmente, de artigos científicos publicados entre 2003 e 2008, nas línguas portuguesa, inglesa, espanhola e francesa, relacionados com os métodos de diagnósticos complementares das LER-DORT (ressonância magnética, tomografia computadorizada, ultrassonografia e eletroneuromiografia). As jurisprudências foram obtidas através da busca dos julgados sobre o tema, entre 2003 e 2008, pertencentes ao Supremo Tribunal Federal, Superior Tribunal de Justiça, Tribunais Regionais Federais, Tribunal Superior do Trabalho e Tribunais Regionais do Trabalho. Resultados: foram identificados 48 artigos abordando os aspectos diagnósticos das LER-DORT, observando-se que os exames por ressonância magnética, ultrassonografia e eletromiografia demonstraram ser mais efetivos, dentro das suas especificidades, para a complementação do exame clínico de patologias relacionadas às LER-DORT. A análise das 123 jurisprudências selecionadas demonstrou, de forma geral, que as LER-DORT equiparam-se ao acidente de trabalho, devendo apresentar nexo de causalidade (atestado através de laudo médico-pericial) e, ainda, ensejam a ação por danos morais, a qual, devido à EC nº 45 passou a ser competência da Justiça do Trabalho. O Estado da arte dos aspectos periciais encontra-se representado pela vigência da Instrução Normativa n. 98/2003, a qual traz como aspecto fundamental a determinação de novos parâmetros a serem considerados na definição de um quadro de LER-DORT, dispondo, ainda, sobre a conduta ética que deve ser adotada pelo médico perito, bem como chama a atenção para a necessidade dessas doenças do trabalho serem comunicadas às autoridadades competentes, através da emissão da Comunicação de Acidente de Trabalho (CAT). Conclusão: as LER-DORT representam, hoje, um problema de importante impacto, não apenas previdenciário, mas também econômico em diversos países, nos quais o Brasil encontra-se inserido. Estudos sobre o estado da arte relacionados às LER-DORT são fundamentais para auxiliar na construção de um modelo crítico e consciente que colabore com a garantia de sustentabilidade do sistema previdenciário no Brasil

Avaliação da incontinência urinária de esforço em mulheres na pós-menopausa com e sem queixa de perda urinária através da aplicação do pad-test de 1 hora

Stress urinary incontinence (SUI) is defined as "involuntary loss of urine" due to several processes that alter the ability of the bladder to hold urine properly, regarded as a social and hygienic problem that adversely affects quality of life. In postmenopausal women, IU is associated with atrophy and weakness of the pelvic floor muscles. The objective this study was investigate, using the onehour pad test, stress urinary leakage (SUI), evaluate and compare their results in postmenopausal and premenopausal women. The survey was characterized as a cross-sectional study. The study consisted of 60 postmenopausal women were divided into GIU - consisting of 34 volunteers complaining of involuntary loss of urine during stress - and GSIU - consisting of 26 volunteers without complaints of loss of urine during stress, and 15 women, during the premenopausal (GPM), and ovulatory with normal menstrual cycle. All volunteers were evaluated clinically, subjected to one-hour pad test, after the biochemical evaluation of blood and sex hormones. Statistical analysis was performed by descriptive analysis, ANOVA, Turkey´s post-test and Pearson correlation. The results showed that 100% of postmenopausal patients had involuntary loss of urine during one hour pad test (GIU: 4.0 g; GSIU: 4.5 g). GPM remained continent after an hour pad test (GPM: 0.4 g). In addition, Pearson showed a strong correlation between urine loss with time since menopause (r = 0.8, p <0.01) and body mass index - BMI (r = 0.7; p = 0.01). These data suggest that the one-hour pad test is a useful test to assess and quantify urinary leakage, including those volunteers who had no previous complaint of SUI

O desenvolvimento sustentável na ordem constitucional e sua promoção através do planejamento urbano

The man, being subject and object of their changes, has passed by many process to find a better life way. Since your existence, he finds to live in groups for make easy your life and make concrete yours desires. All by history, when the individual´s rights was establishment, collectives and lonely way, contribute for evaluate the relationship between individuals and they own, and them and state, which has a duty to those, positive or negative, depending on the case. The circle of fundamentals rights has been sustainable development and the concept of growth economy associated to the environment protection. This association reflect a apparent conflict between values very distinct, but the constitutional interpretation can be reunite both of them and make it live in harmony; values of environmental order and economical order can be exist together, as long as the state contribute to this. On the city, where the most of relationships happening, the urban plan appear how a effective way of sustainable development, finding the harmony between the growth economy and environment protection. To effective the socials functions of the city (inhabit, circulate, work and entertainment) and the citizen´s life quality, the city is the scenery that show how the urban plan, across established previously legal instruments, like the governmental public politics, to effective the right to development, right of third generation. The director plan how effective tool for local needs - obligation defined by Citizen Statute that contribute for the program linked defined by the urban plan. The state´s intervention on the private sector of citizen, and the restriction on their rights are be justified by the collective´s rights and their quality of life. So, in front the urban scenery has been the plan to make social functions of city, the healthy way of life, which is the sustainable development

Federealismo e desenvolvimento: cooperação entre os entes federados limites, direitos e deveres

Taking as a starting point the Classic Federalism and theory of the development this Work intend to present some ideas linked about cooperation between federal entities and intergovernmental relations with the main focus the regulation by the Public Consortia aimed at administrative efficiency as a Constitutional Principle of Activity Administrative, against the current provisions of the Federal Constituition of 1988, and infraconstitutional legislation in order to provoke debate and criticism about the principle of cooperation adopted as a paradigm and the capabilities that the state has and what it is, in fact, an efficient management public. It is in the growth of the state, and not a decrease as a minimal state, which aims to discuss its role in promoting the collective interests, and it is therefore essential, as an institution able to intervene on citizens in the search for socially relevant results. Study Federalism and Development on the premise of public consortia and administrative efficiency requires study the course of history as the formation of the Brazilian State, in particular the fact that he is in joint effort between federal agencies - federal, state and municipal - in order to better review the relations established in this plan, in what concerns directly on the issue of division of powers, especially the common or competitors and the subject of the highest relevance for the implementation of an effective federal pact. Finally, the objective of this Work is not only particularize the institute of public consortia, it is intended to demonstrate the deviousness of the concept of efficiency and the division of powers of federal agencies and the constitutional contribution of the institute as a program that should be put in a tone of debate, adequacy of the practice and the law itself

Guerra contra as drogas: uma análise sob a perspectiva do princípio da proporcionalidade

As substâncias entorpecentes acompanham a humanidade desde o início da civilização. No entanto, várias delas foram consideradas proscritas ao longo do tempo. Seu combate foi inaugurado na comunidade internacional a partir do começo do século XX. No início, tinha o condão eminentemente moral, porquanto a proibição encerrava, por princípio, a proteção da ética ameaçada pelo padrão desviado do consumo de estupefacientes. Na década de 1970, a guerra contra as drogas, expressão cunhada nesse período, evoluiu para se tornar o meio pelo qual o consumo seria mitigado. Dez anos mais tarde, ante à impossibilidade de sucumbir o narcotráfico, passou a ser um fim em si mesma o novo argumento para os esforços militares dos Estados Unidos da América. A criminalização das substâncias entorpecentes consideradas ilícitas é fundamento jurídico da guerra contra as drogas. Esse modelo proibicionista encontra argumento no direito penal do inimigo, segundo o qual o Estado pode, em situações que exponham a coletividade a grave perigo, negar à determinada categoria de criminosos (os inimigos) as garantias inerentes ao direito penal, cabendo-lhes apenas a coação estatal. Mesmo tendo consumido trilhões de dólares, encarcerado aos milhões e custado a vida de milhares de pessoas, pode-se dizer que a guerra contra as drogas não reduziu a oferta e o consumo de substâncias entorpecentes consideradas ilícitas, nem mitigou os danos delas decorrentes pelo contrário, tornou-se um problema de segurança pública. Assim, impõe-se a verificação da constitucionalidade da norma penal que fundamenta a guerra contra as drogas, sob ponderação do princípio da proporcionalidade. Referido postulado cobra que a norma seja adequada, cumprindo a finalidade pretendida, necessária, não havendo meio menos gravoso à obtenção do mesmo fim, e proporcional, estrito senso, que a sanção imposta ao indivíduo seja equivalente ao dano que se quis prevenir. Em matéria penal há de se incluir um outro elemento, a ponderar se as consequências da proibição em matéria penal, por si só, são mais graves que os consectários dos fatos que se pretendem proibir - exige-se que a lei seja socialmente menos ofensiva. A norma penal que fundamenta a guerra contra as drogas não se mostrou hábil a mitigar os danos sociais delas decorrentes sendo, por isso, inadequada. Existem meios alternativos à criminalização mais eficientes à esse objetivo, pelo que se faz desnecessária. Na medida em que estupefacientes mais nocivos à coletividade são considerados lícitos, a criminalização de drogas menos danosas se mostra desproporcional. E, uma vez que dela resultam graves danos à sociedade, não atende ao critério da menor ofensividade social. É, portanto, inconstitucional

Padrões cromossômicos e mapeamento de genes ribossomais 18S e 5S em peixes pelágicos Atlânticos

Cytogenetic studies in fish have been contributed significantly to a better understanding of the marine biodiversity, presenting information related to characterization, evolution and conservation of species e fisheries stocks. Among the marine species which cytogenetic data are less well known pelagic forms are detached, that despite the economic importance and conservation efforts have been suffering great pressure from the artisanal and industrial fisheries. The present work characterized cytogenetically six species of large pelagic fish in the Atlantic, belonging to the Order Perciformes, among them, four species of Scombridae, Thunnus albacares, T. obesus, Scomberomorus brasiliensis and Acanthocybium solandri and two Coryphaenidae, Coryphaena equiselis and C. hippurus using Classical cytogenetic methods as conventional staining, C-banding and Ag-NORs and molecular through staining fluorochromes AT and GC-specific and mapping of ribosomal multigene families, 18S and 5S. The identification of phylogenetic patterns and cytotaxonomic markers between the species and the presence of sex chromosomes in at least one species of Coryphaenidae, are particularly useful in the formulating of phylogenetic hypotheses, as well as comparisons between groups and populations

Arranjos produtivos globalizados: o caso do APL da fruticultura de melão de Mossoró - Baraúna-RN

This study discuss the issue on Clusters Global, the productive arrangement of fruits melon Mossoró/Baraúna in Rio Grande do Norte, located in the Potiguar semi-arid RN, is entered in the arket international level, the job serch, from the benchmark neo-schumpeterian, strongly condensed and absorbed in Brazil by focusing on Local Productive Arrangements set out by the Reseatch Netwoark on Sistemas Produtivos e Inovativos Locais (REDESIST), understanding the extent to which innovation efforts, and as interactions between the main actors that make up this APL in particular, account for its global insertion. The methodology includes the application of questions to the producers of melon arrangement as well as interviews with the main responsible for the support, promotion and financing. In conclusion, there is a significant interaction between producres and actors of the arrangement, a fact that contributes to the integration into the international market together with the implementation of relevant innovations. Finally, it is pointed out the need for public policies directed to the production of melon because of its relevance to the exports of Rio Grande do Norte

Programa alfabetização solidária: um estudo sobre a experiência no município de Lagoa de Pedras/RN (1997 - 2003)

The educational reform of the 90 s was tainted by the objectives of the fiscal adjustments, resulting in the redefinition of the state s role in the financing and offering of teaching services, and bringing about a shuffling of the responsibility between the public and private sectors to promote education to young people and adults. The 90 s also highlighted the proliferation of providers and the multiplication of Educational Programs for Youths and Adults (EJA), implemented through partnerships between governmental and nongovernmental agencies. During this period of time, the agenda of educational responsibilities concerning analphabetism was organized in a process of decentralized of the state, with the following political, social, and economic objectives: to reduce the public deficit, increasing public savings and the financial capacity of the state to concentrate resources in areas considered indispensable to direct intervention; to increase the efficiency of the social services moffered or funded by the state, giving citizens more at a lower cost, and spreading services to more remote areas, expanding access to reach those most in need; to increase the participation of citizens in public management, stimulating communitarian acts as well as developing efforts towards the effective coordination of public figures in the implementation of associated social services. Thus, Assistance Programs co-financed by the government try to deal with the problem of analphabetism. Within the sphere of the 90 s educational policy decentralization, we come to see how the agenda dedicated to the reduction of analphabetism was formed by the Solidarity Alphabetization Program (PAS). Between 1997 and 2003, the latter agenda s decentralizing proposal was integrated in the management partnership for the operationalization of tasks and resources faced with the execution of the formal objectives. In this study, we identify the dimensions of the implantation and progress of the tasks carried out by PAS, in the municipality of Lagoa de Pedras/RN. However, we consider these Programs to assist in the process without guaranteeing the reduction of the causes or substituting the responsibility of the system once the monetary resources for program maintenance provided by the partners is exhausted

Entre cristo e o diabo:o ideário do Colégio Americano Batista do Recife (1902-1942)

Due to lack of work on the history of Baptist schools in the Northeast region of Brazil, it is important to understand through a historical reconstruction of the Baptist Protestant education. We embarked on this venture as a chance to understand the presence of Protestant schools, and his ideas on Brazilian soil. Our goal is to promote a reflection which has the axial dimension of the Baptists Protestant education, in time, we will place the debate between 1902-1942. The temporal boundaries of 1902-1942 was because 1902 was when he started the American Baptist College of Recife in 1942 and that ends the cycle of managing directors of Americans. Understand the functionality of time a school is justified when we realize that the history of education is the story of a work of self and formation within a framework that has the school as the main support that can enable a reading of reality. We also intend to examine the school culture brought to Brazil by American missionaries and their applicability in the Brazilian cultural-historical context. And just to demonstrate the hypothesis that the educational contribution of Baptists added to the participation of other Protestants promoted advances in Brazilian society. Possibly taking for granted that the Baptists were in possession of the democratic ideals of religious freedom, taken by many representatives and religious version of the republican regime. In addition to promoting a model in Brazil to make different methodological schools, based on the ideals of new school and ethics of the Bible. Our proposed research aims at understanding how North American missionaries settled in Brazil and what were the purposes of adding to the efforts of evangelization to formal education, binomial that justified the establishment of schools. A vision of saving men for evangelization and education of the Devil attack victims over the ethics of Christ

O brincar e a criança com deficiência física na educação infantil : o que pensam as crianças e suas professoras

The present study had the purpose of examining the disabled children s way of playing on everyday situations in the CMEIs (acronym in Portuguese for City s Early Childhood Education Center ) of Natal/RN, by watching and listening to three children and their teachers, trying to understand how the games existent in these contexts involve the different subjects of the learning process, and which contributions emerge for a valuable pedagogic work, capable of providing the children s inclusion in the Early Childhood Education. This qualitative investigation was built as a case study, collecting data through watching and interviews. Throughout the observations, it was indispensable to look into the different contexts of the school routine, to capture and analyze events that could answer to what was being studied. The accessibility conditions of the school spaces were also observed. The interviews made possible to extract from the subjects what they think and how they perceive themselves when playing. The acquired data were analyzed having as counterparts contemporary studies and theories about playing, childhood and school inclusion, and published documents from the Education and Culture Department that treat of this theme as the guiding axis of the pedagogic proposes aimed to the Early Childhood Education. The revelations of the research show that is necessary to put effort on the disabled children s playing inside the context of the Early Childhood Education, regarding the accomplishment of accessibility laws that treat of school spaces and providing of equipment and resources that respect those children s characteristics, as well as providing opportunities for initial and continued training for the teachers, under the perspective of inclusive education and playing
