Water-soluble Cu, Fe, Mn and Zn species in nuts and seeds

An approach was developed to estimate molecular weight distribution of water-soluble Cu, Fe, Mn and Zn species in Brazil nut, cupuassu seed and coconut pulp by size exclusion chromatography (SEC) coupled on-line to ultra-violet (UV) and off-line to graphite furnace atomic absorption spectrometry (GF-AAS) detectors and matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF-MS). SEC-UV analytical signals showed the prevalence of high molecular weight (HMW) species (79-1.7 kDa for Brazil nut, 50-1.7 kDa for coconut pulp, and 34-1.7 kDa for cupuassu seeds). The Brazil nut SEC-UV, GF-AAS and MALDI-TOF mass spectra gave confirmation of the association of the elements with water-soluble compounds. The elemental profiles were associated with fractions of compounds of molecular weight 1.2-16 kDa for Brazil nut, 1.7-13 kDa for coconut pulp, and 1.2-7.6 kDa for cupuassu seeds.

Clusters de pequenas e médias empresas na área de produtos regionais: uma estratégia alternativa de desenvolvimento industrial sustentado na Zona Franca de Manaus

Este trabalho mostra que o fomento de clusters na área de produtos regIOnaIS - particularmente compostos por empresas de micro, pequeno e médio porte - representa uma estratégia alternativa econômica futura para a Zona Franca de Manaus - ZFM e o resto da Amazônia Ocidental. Além dos fundamentos teóricos relacionados aos clusters e pólos de desenvolvimento, o estudo baseou-se também nas evidências empíricas de quatro empresas de Manaus que operam com produtos regionais amazônicos. A pesquisa detecta a formação inicial de um cluster na área de produtos regionais que necessita de uma interação maior entre todos os agentes locais, a fim de ser operacionalizado. Conclui que estratégias econômicas para exploração das potencialidades regionais podem levar ao desenvolvimento de clusters de indústrias baseada na biodiversidade da região que usará matéria-prima local e conhecimento. Desta maneira, as estratégias de desenvolvimento sustentado podem trazer de volta muitos beneficios à região Amazônica e contribuir para a diversificação da atual base industrial da ZFM.

Estruturação e processos isomórficos do campo organizacional de alambiques de cachaça artesanal em Bananal - SP

This work tries to comprehend, throw the prism of the Institutional Theory, the structural process of organizational field of cachaça¿s handicraft producers¿ from a Brazilian countryside region. The role of values and traditions on the determination of the structure and decision making on this industry are analyzed. It is necessary to research historic, economic and social facts, and confront them to the formation of Brazilian society to understand the field¿s formulation. An important aspect of this research is the mapping of isomorphic process and the comparison of the field¿s institutional degree, before and after the changes. It was noticed that the alteration on perception of Cachaça in the national market and the entrance of a new actor oriented by functional rationality are the major reasons for the mimetic changes on this field. As a contribution, this study confirms the applicability of Institutional Theory on analysis of specific fields and shows how this field has structured itself.

Iranduba: ribeirinhos na travessia produzida: análise de um projeto para populações rurais no Estado do Amazonas

A presente dissertação centra-se na análise do processo de "exclusâo" - »integração" a que estão submetidas as populações ribeirinhas no estado do Amazonas, e busca reconhecer o seu campo de autonomia como mecanismo básico de sua reprodução, isto é, como vivenciam e respondem as formas concretas de subordinação." O trabalho foi desenvolvido na região do médio Amazonas, no município de Iranduba onde ocorreu uma intervenção do Estado através da criação de um Núcleo de Colonização. Dirigida em terra firme e da implantação do Projeto Cidade Hortigranjeira de Iranduba, em 1976. Essa intervenção é aqui tratada como Travessia dos Ribeirinhos.

Biodiesel do dendê: um estudo de viabilidade econômico financeira no Estado do Pará

O objetivo deste estudo é analisar três modelos de operação de uma usina de extração de óleo de palma, de óleo de palmiste, e de biodiesel, respectivamente, em conjunto com a produção de dendê pela agricultura familiar, visando o fornecimento exclusivo de matéria-prima para a indústria através da parceria com Programa Nacional da Agricultura Familiar. O projeto consiste na construção de uma usina de grande porte, a partir de investimentos de fontes públicas e privadas voltados à construção do complexo industrial e ao financiamento da implantação do cultivo de dendê pelos agricultores. Foram construídos quatro cenários, onde foram analisados os indicadores de performance econômico-financeira de avaliação do arranjo produtivo da indústria e da parte agrícola. Esses cenários visam a tomada de decisões de investimentos, através da utilização dos indicadores econômico-financeiros clássicos para avaliação da viabilidade do dendê como matéria-prima para o complexo industrial da usina. Entre os indicadores utilizados neste trabalho podemos citar como principais: o VPL (Valor Presente Líquido) e a TIR (Taxa Interna de Retorno), e indicadores secundários utilizados como suporte para as análises, tais como Payback Descontado, TIRM (Taxa Interna de Retorno Modificada), dentre outros. Além de indicadores sociais, como geração de renda para as famílias de agricultores, com o objetivo principal de criar valor monetário, gerar emprego e renda e pagar os recursos dos investidores púbicos. A implantação do dendezal está fundamentada no Zoneamento Agroecológico do dendê e será executada em áreas degradas por pastagens para garantir a sustentabilidade, contribuir para a recuperação ambiental através do sequestro de carbono e diminuir a pressão sobre as florestas nativas. Consequentemente, espera-se que o projeto contribua para evitar o avanço do desmatamento na região da Amazônia legal. Para tanto, foram realizadas visitas às plantações de dendê e à usina da Biopalma. Também foram realizadas visitas à Embrapa Ocidental na cidade de Manaus e Embrapa na Cidade de Campinas. Foi proposto um modelo de análise econômica financeira baseado em implantação de uma usina de grande porte para a produção de Biodiesel no Estado do Pará. O estudo apresentou, dentre suas limitações, o fato de ser complexo e amplo. A inexistência de projetos de usina grande envergadura totalmente implantados e funcionando com emprego de tecnologia e capital intensivo, como também a impossibilidade de se realizar esta pesquisa de amplo espectro sem um número consideravelmente maior de organizações envolvidas. Como resultado, os indicadores economicos analisados mostram que há viabilidade do projeto em três dos quatro cenários construídos, demonstrando que o capital dos investidores públicos, privados e do agricultor familiar serão remunerados utilizando às taxas de juros, prazos, condições do mercado de capitais. O objetivo é atrair investimentos para a produção de biodiesel, implantação de empreendimentos agrícolas, indústriais, geração emprego e renda para Agricultura Familiar na cadeia produtiva do dendê.

Projeto de transposição de águas do Rio São Francisco: uma análise à luz do processo de agenda-setting

Quais condições permitiram que o Projeto de Transposição de Águas do Rio São Francisco deixasse de figurar no imaginário daqueles que o defendiam, como o vinha sendo desde os idos do período imperial, e, começasse a ser efetivamente implementado somente em 2007? Responder a esta questão corresponde ao objetivo principal deste estudo. Para tal, o Projeto São Francisco, como também é conhecido, foi analisado à luz do modelo de multiple streams, concebido por John Kingdon (2003), orientado para a compreensão sobre como algumas questões passam a fazer parte da agenda de governo, recebendo atenção dos formuladores de políticas públicas, enquanto outras são ignoradas. Por meio do modelo de multiple streams, foi possível apontar os principais diagnósticos e alternativas historicamente apresentados para a região do semiárido brasileiro, frente à questão dramática das secas recorrentes. Além disso, foi estruturado o complexo jogo político da transposição, caracterizado pelo conflito entre coalizões atuantes em múltiplas arenas decisórias. A partir do mapeamento da forma como os atores políticos se apropriaram dos diagnósticos e alternativas apresentados para a região, com o intuito de impor aos demais as suas crenças sobre qual deve ser o melhor caminho para o desenvolvimento do semiárido, foram identificadas as janelas de oportunidades (policy windows) que tornaram viáveis a execução do projeto de transposição.

Embolada e outras coisas do folclore tulusano . a experiência da associação escambiar em Toulouse - França

Since the middle 80 s from the 20th century, some musical genres associated to the Brazilian Northeastern region notably the forró, coco de embolada and repente de viola have been gradually incorporated to the musical production of south France linked to the occitanista trend, currently linking many musicians and groups from those regions in both countries. This paper is engaged in reflecting on the particular experience of the groups formed by the Escambiar Association, located on the city of Toulouse, and specially the duet Fabulous Trobadors, whose compositions are mostly made in the coco de embolada form. Watching the motivations and the processes that led to the creation of the groups from this association and it s current operation, this study investigates the transcultural phenomenon, that allow to cross two symbolic universes through rationalizing speeches about music, considering the locality s production in the midst of a political debate that involve questions about cultural identity and tradition

A travessia do trágico no romance d A Pedra do Reino de Ariano Suassuna

The present work seeks to investigate and discuss about the Greek Tragedy s elements at Ariano Suassuna s romance called τ Romance d A Pedra do Reino e o Principe do Sangue do Vai e Volta, connecting it directly to mythic, epic, poetic, and romances aspects at his work. The romance has as the protagonist the backcountry Pedro Dinis Quaderna. Quaderna is a character which is simultaneously popular, elitist, enigmatic, naive, and an intellectual man that has a great erudition. Quaderna is a character that seeks, by using the Literature, to reestablish a Brazilian backcountry kingdom which he s supposedly the king, always trying to empathizes the Brazilian northeast region like if it was a nation apart. By impressing a national personality to the Brazilian northeast , Quaderna tries to become an epic poet just like Homer, denoting a strong influence of the Epopee. Quaderna, just like many characters of Greek Tragedy, has at his family past time a lot of tragic circumstances. These facts that ocurred to his relativos like the your uncle Pedro Sebastião Garcia Barreto s death, the disappearement of his cousin Sinésio, and the contest between the brothers Arésio and Sinésio, and others aspects, remind us remarkable influences, beyond the Epopee, of the Greek Tragedy. By reading the romance we may notice many similarities between Quaderna s trajectory and Greek Tragedy heroes. To make an analysis about the tragic aspects at Suassuna s work, we need to dialogue with many theoreticals that have written about the tragic and comparate with many parts of Suassuna s with classics character s texts of Greek Tragedy. At the following chapters we seek to provide romance s elementaries notions, as well as tragic notions, the dialogue with mythics aspects and the tragic and epic aplicability at Suassuna s work

Variação temporal da Comunidade de macroinvertebrados bentônicos em um riacho intermitente do semiárido brasileiro

In Brazilian semiarid region, the majority of water bodies are temporary and the biodiversity in these ecosystems is poorly known. The goal of this study was to describe the temporal variation of benthic macroinvertebrates in an intermittent stream in the Brazilian semiarid region. From March to July of 2009, surveys of benthic macroinvertebrates and water physiochemical parameters were done in a first order stream located at Piranhas-Açu River basin. 25 macroinvertebrates families were found, 21 belonging to Insecta class. The chironomids were the most abundant group during all study period and were represented by 19 genus. The largest densities and taxonomic richness were seen in the drying phase of the stream while the smallest values were found in the period with the heaviest rainfalls ( wet phase ). Only the families Chironomidae and Ceratopogonidae were found during all study period, suggesting that these groups have better adaptations to support floods and droughts. Furthermore, these two groups seemed to be pioneering in this stream. Among the chironomids, Paratendipes dominated the period of floods while Tanytarsus were more abundant in the drying phase . This study showed that hydrological fluctuation is the main force influencing the macroinvertebrate community in this stream, therefore, efforts seeking the conservation and management of Brazilian semiarid water bodies should consider this high natural variability in flow regime

Hospital humano: etnografia da humanização hospitalar na perspectiva de usuários

This ethnographic work studies the experiences of patients admitted in public (PUH) and private (PRH) hospitals in the Brazilian northeastern region. 28 adult patients of different clinics participated in the study. Data were analyzed by the patient path method, consisting in a combination of complemented and articulated techniques free observation, participating observation, ethnographic interview and patient testimonials collected prospectively during the patients admissions, from their arrival and until their discharge. The analysis was carried out according to the Thematic Categories Analysis Technique and the data were interpreted pursuant to medical anthropology, healthcare humanization and healthcare promotion theoretical references. The ethical principles of Resolution 196/96 were followed. The human hospital, as revealed by the patient, highlights the significance of subjectivity. 225 (54.7%) out of 411 mentioned concepts were collected in a public hospital (PUH) and 186 (45.3%) in a private institution (PRH). The results show that the patient at the PUH and PRH ethnoevaluates different aspects of the healthcare professionals´ human and technical competence, the hospital´s functioning structure, the access to and the ethics in the financial management, and develops overcoming strategies for his stay at the hospital. This ethnoevaluation is mediated by different factors, namely: social and economic status, personality, religiosity, ironic speech, somber diagnosis and satisfied needs, prior hospital experiences and the conditions under which the interview was carried out. A pedagogic proposal for the hospital humanization must include structural, managerial and organizational changes of the offered services and use active methodologies aimed to the political resolution of problematic situations at work and the inclusion of affective and subjective factors, and become as well a tool for the collective learning. This study shows the importance for the user´s ethnoevaluation to be incorporated into the hospital management and care as a guideline in the decision making and clinical action, thus promoting practices that shall lead to a decent and humanized care. The multidisciplinary nature of this study allowed a wide understanding of the user´s perspective as a socially critical ethnoevaluator

Desenvolvimento, sustentabilidade e conservação da biodiversidade na amazônia: a produção familiar agroextrativista em áreas protegidas no sul do amapá

The establishment of Extractivism and Sustainable Development Reserves comes from an amazon forestry people resistance initiative. It means an option of natural resources management as protected areas for agroextractivism purposes. According to the institutional point of view, these lands, called Conservation Unity for Sustainable Exploration, belong to the government which grants the usufruct rights to the agroextractivist families under a sharing territory administration agreement among government and rural communities. The main roles of these lands are both: to improve the dwellers wellbeing, and protecting the local biodiversity. Additionally, they also represent the start of this thesis theme entitled Development, sustainability, and biodiversity conservation in the Amazon region: the use of protected areas for agroextractivism domestic yield in south of Amapá state with the objective of analyzing the performance that each territory has been reaching in terms of the attributions proposed at the beginning, when they were created. Social, economics, and environment changes that occurred in the agroextractivist areas have been evaluated from two selected test sites, named Rio Cajari Extractivist Reserve and Rio Iratapuru Sustainable Reserve, both, localized in the south of Amapá state

Trabalho, pobreza e caridade: as ações do Padre Ibiapina nos sertões do Nordeste

This work started from an investigation concerning the process of education, moralization and disciplining of the poor in the backlands of the Brazilian Northeast region, in the second half of the 19th century, through the incorporation of the values of productive work. In order to do so, we took as our field of investigation the missions of Father José Antônio Pereira Ibiapina (1806-1883), in which an extensive work was developed, including the construction of twenty two (22) charity houses in the States of Rio Grande do Norte, Paraíba, Pernambuco, Ceará e Piauí, but also of weirs, churches, graveyards, hospitals and so forth. Given the socio-historical character of the research, we adopted qualitative methods of analysis and the following procedures: survey and analysis of documents, statute and internal rules that ordered the workings of the charity houses; biographies on Father Ibiapina and the missions‟ reports, as well as various sorts of publications on the missionary. Our study comprises his 27 year-period of missionary-religious activity (1856-1883), and undertakes an analysis on the topic of poverty, since the medieval Christian take on it until modernity, when it stops representing a value and becomes a problem to be solved through work. The socio-political context in which Ibiapina lived in the Northeast was marked by the consequence of droughts and economic crises in the region. The analysis of the documents indicates that, in the circumstances of political weakness and lack of interest for regional demands by the national political agenda, his missionary actions produced strong effects. Starting from an ethics of valorization of work, which combined modern and traditional elements, his actions set up disciplinary, moralizing and civil educational practices of the poor, founding, simultaneously, a pragmatic religious experience directed at the resolution of the problems caused by poverty. In that sense, we observe that such actions are connected to the broader process of moralization and education of the poor, but the analysis also suggests that their inscription into the social order articulated both forward as well as conservative aspects of the established system

Determinantes locais da decomposição foliar e de raízes finais em um ecossistema semiárido do nordeste brasileiro

The decomposition process exercises an extensive control over the carbon cycle, affecting its availability and nutrient cycling in terrestrial ecosystems. The understanding of leaf decomposition patterns above the soil and fine roots decomposition below the soil is necessary and essential to identify and quantify more accurately the flow of energy and matter in forest systems. There is still a lack of studies and a large gap in the knowledge about what environmental variables act as local determinants over decomposition drivers. The knowledge about the decomposition process is still immature for Brazilian semiarid region. The aim of this study was to analyze the decomposition process (on leaves and fine roots) of a mixture of three native species for 12 months in a semiarid ecosystem in Northeast Brazil. We also examined whether the rate of decomposition can be explained by local environmental factors, specifically plant species richness, plant density and biomass, soil macro-arthropods species richness and abundance, amount of litterfall and fine root stock. Thirty sampling points were randomly distributed within an area of 2000 m x 500 m. To determine the decomposition rate, the litterbag technique was used and the data analysis were made with multiple regressions. There was a high degradation of dead organic matter along the experiment. Above ground plant biomass was the only environmental local factor significantly related to leaf decomposition. The density of vegetation and litter production were positively and negatively related to decay rates of fine roots, respectively. The results suggest that Caatinga spatial heterogeneity may exert strong influences over the decomposition process, taking into account the action of environmental factors related to organic matter exposure of and the consequent action of solar radiation as the decomposition process main controller in this region

Emprego formal na região nordeste brasileira: seus efeitos na inclusão social

This work aims to study the problem of the formal job in the Brazilian Northeast region and its effect in the social inclusion, taking for base the analysis of variables defined in the Atlas of Social Exclusion, which is based on the 2000 Brazilian Census, choosing the county as unit of analysis. As methodological options, an exploratory data analysis was performed, followed by multivariate statistical techniques, such as weighted multiple regression analysis, cluster analysis and exploratory analysis of spatial data. The results pointed out to low rates of formal job for the active age population as well as low indexes of social inclusion in the Northeast region of Brazil. A strong association of the formal job with the indicators of social inclusion under investigation, was evidenced (schooling, inequality, poverty, youth and income form government transfers), as well as a strong association of the formal job with the new index of social inclusion (IIS), modified from the IES. At the Federative Units, in which better levels of formal job had been found, good indexes of social inclusion are also observed. Highlights for the state of the Rio Grande do Norte, with the best conditions of life, and for the states of the Maranhão and Piauí, with the worst conditions. The situation of the Northeast region, facing the indicators under study, is very precarious, claiming for the necessity of emphasizing programs and governmental actions, specially directed to the raise of formal job levels of the region, reflecting, thus, in improvements on the income inequality, as well as in the social inclusion of the population of Northeastern natives.

Retratos, imagens, letras e numeros colados nas paredes:representaçãoes sociais de escola para ribeirinhos dos rios Môa e Azul - Acre

Remote Communities. Absence of artifacts and minimization of the exacerbated consumption of modernity. The desire which spread beyond what reality can provide. Expressions like this are present in this paper which focus in the social representations of school built by residents who live at the riversides of Môa and Azul Rivers, in Mâncio Lima, Acre State. To do so, we used the methodological contribution of the semi-structured interview, observation of the place while a natural inhabitant of the region, and also photos analyses of local reality. A key feature of the riverside homes is the glued paper on the walls of houses forming a panel set of portraits, pictures, letters and numbers for all appreciated. Regardless of whether or not read, there is admiration for the color of the images, the layout of the letters, and the things of the city awakening the desire to obtain school knowledge. The resident of this Amazon region maintains a close relationship between thinking, acting and feeling living harmonically with nature that connects them to the ideal landscape which is revisited by the graphic material that attracts wondering what exists beyond the shores of the river, beyond the horizon of green forests. It is a life entirely accomplished by the imaginary where exist a framed landscape merged and confused by the real and the supernatural, in which men and gods walk together by the forest, sailing by the rivers and seek a possible aesthetic between the real and ideal. The Theory of Social Representations spread by Serge Moscovici (2005) and Jodelet (2001) guided our gaze on the understanding what the school is and its representation to the riversides, as well to reveal the relation they practice with the knowledge that is spread by the mystification and the knowledge that is practice daily. Based in Bardin s thematic analysis (2004) we tried to raise such contents combining them in five analysis categories
