Metagenômica comparativa de solo de regiões de mata atlântica e caatinga do estado do Rio Grande do Norte - Brasil

The microorganisms play very important roles in maintaining ecosystems, which explains the enormous interest in understanding the relationship between these organisms as well as between them and the environment. It is estimated that the total number of prokaryotic cells on Earth is between 4 and 6 x 1030, constituting an enormous biological and genetic pool to be explored. Although currently only 1% of all this wealth can be cultivated by standard laboratory techniques, metagenomic tools allow access to the genomic potential of environmental samples in a independent culture manner, and in combination with third generation sequencing technologies, the samples coverage become even greater. Soils, in particular, are the major reservoirs of this diversity, and many important environments around us, as the Brazilian biomes Caatinga and Atlantic Forest, are poorly studied. Thus, the genetic material from environmental soil samples of Caatinga and Atlantic Forest biomes were extracted by direct techniques, pyrosequenced, and the sequences generated were analyzed by bioinformatics programs (MEGAN MG-RAST and WEBCarma). Taxonomic comparative profiles of the samples showed that the phyla Proteobacteria, Actinobacteria, Acidobacteria and Planctomycetes were the most representative. In addition, fungi of the phylum Ascomycota were identified predominantly in the soil sample from the Atlantic Forest. Metabolic profiles showed that despite the existence of environmental differences, sequences from both samples were similarly placed in the various functional subsystems, indicating no specific habitat functions. This work, a pioneer in taxonomic and metabolic comparative analysis of soil samples from Brazilian biomes, contributes to the knowledge of these complex environmental systems, so far little explored

A Geração de inovação na carcinicultura do RN: Uma análise a partir da imersão social

This dissertation examines the organizational innovation as a nonlinear process, which occurs in a social and political context and, therefore, socially immersed. Examines the case of shrimp in the state of RN, starting from the following problem: although the norteriograndense shrimp occupies the largest producer of farmed shrimp from Brazil, has a series of bottlenecks concerning the generation of industry innovation, concerning the social relationships and policies between the various actors in the network, whether private or public, and its consequences in terms of opportunity and limits generated for the innovative dynamics. The objective of the research is to understand how the social embeddedness of political actors affects norteriograndense shrimp within the context of structural relations, the industry generation of innovation, throughout its technological trajectory . The approach of social embeddedness balances atomised perspectives, undersocialized and oversocialized, of economic action, considering both the human capacity to act as sources of constraint, whose mechanisms are analyzed the structural and political. In methodological terms this is a case study, analyzed from the research literature, documentary and experimental. Primary data were collected through semi-structured interviews and analyzed in depth by the technique of content analysis. Was adopted a longitudinal approach, seeking to understand the phenomenon from the perspective of the subjects, describing it in an inductive process of investigation. After characterizing the sector and defining their technological trajectory, the analysis of the results followed its four stages: (1) Introduction of Technology: 1973-1980, (2) Intensification of Research: 1981-1991, (3) Technological Adaptation, 1992 -2003, (4) Technological Crisis: 2004-2009. A cross-sectional analysis along the evolutionary trajectory revealed the character of structural changes and policies over time, and implications on the generating process of innovation. Note that, the technological limit to which the sector reached requires changes in technology standards, but is more likely that the potiguar shrimp is entering a new phase of his career in technology rather than a new technological paradigm

Jovens terena na cidade de Campo Grande (MS) Política e geração

Research with indigenous in urban context are gaining steam in recent years, particularly with the intensification of migration resulting from problems such as lack of land for subsistence. However, in relation to Terena, subjects in this study, the contemporary anthropological research aimed at residents in cities still are not privileged, especially to youth. Thus, the dissertation has as main objective the discussion around some axes, among them indigenous youth Terena ethnicity politics, - indigenous movement - and racism. These themes appeared during fieldwork where privileged six trajectories of young Terena who migrated to Campo Grande (MS) and have different ways to mean the city and experiencing everyday life

O terciário (re) desenhando a periferia: a região administrativa norte de Natal/RN, na última década do século XX, servicializada na Av. Dr. João Medeiros Filho

The tertiary sector has been (re)defining and (re)qualifying, in an impacting way, the urban spaces in the cities, introducing new elements for the discussion of the relationship center/periphery. In Natal, as an inducing economic activity of its development, it conforms to the new needs of the capital, expanding, being materialized through several processes and spatial forms. We aim at analyzing one of those processes, which has taken its Northern Administrative Area to (re)define the design of its urban space, through the actions developed by the agents involved with the spatialization of the tertiary activities, at the same time as it redimensions its role as a periphery of Natal, contributing to the study of the recent and growing transformations of the Brazilian capitals. The studied district corresponds to 39.4% of the municipal area and, until recently, was composed by precarious reproduction spaces, unprovided of relevant economical activities. After the boom of the development of extensive housing complexes by SFH/BNH, the area, gradually stopped being a dependent area, and it imposed itself as an economically participant region, with the increase of the trade and services sectors, as well as a favorable place for the appearance of new activities. Its reflexes are noticeable in the achieved spatial configuration. As the main road to induct changes, Dr. João Medeiros Filho Avenue presents these new tendencies in the production of the intraurban space, concentrating the largest goods and services equipments of the area, through investments of the private and public sectors, which guarantee the capital allocation for the construction of a new centrality

Dos movimentos sociais às funções institucionais: a Consolidação de uma geração política em Sergipe.

This study was presented to the Post-Graduation Program in Social Sciences at UFRN as part of the requisites for obtaining the title of Master in Social Sciences. It describes the results of the research From social movements to the institutional functions: the consolidation of a generation . Its main objective is to describe the history of a political generation that emerged from the social movements, in the 80 s, in Sergipe, and that nowadays occupies the main governmental positions in the State s political scenario. As its specific objectives, the research described the emerging of social movements in the 80s in Sergipe; it found in the social movements in Sergipe, in the 80s, the beginning of the history of a new political generation, and described the consolidation of this new political generation in institutional positions as the expression of a new group of power in Sergipe s politics. Among the social movements that gained visibility in that period and that projected their leadership into the political scenario of Sergipe, this study highlights: the students movement, teacher s movement, bank clercks movement, miners movement, and rural workers movement. It utilized as methodology the research in sites, magazines, and the use of testimonies from semi-structured interviews. The main leadership of the five movements that were analyzed is, nowadays, governing the state, administering the capital s city hall, and performing legislative work at the Legislative Assembly of Sergipe, and at the Chamber of City Councilmen of Aracaju. This study described the political history of the main leadership of that generation of militants and organizers of social movements, and of left party groups in Sergipe, highlighting that their consolidation in the political scenario of the State meant the consolidation of a new group of power in Sergipe s politics.

O progama empregador de última instância: Sua relevância em tempos de crises financeiras e sua aplicabilidade ao Brasil.

This dissertation aims to continue the work developed previously concerning the properties of the employer of last resort program (ELR) that would be able to promote a complete elimination of the involuntary unemployment from the economy, so much of the unemployment generated by structural problems as for problems of the conjuncture, as the present world financial crisis. Besides, it intends to deepen the study concerning the applicability of that program to the Brazilian economy, estimating their potential target population in the country and the cost with the workers' remuneration. It was presented the ELR theoretical-conceptual structure and a debate concerning their economic viability; the program properties that turn it more efficient than the onetary and fiscal policies (PMFs) in the fight against involuntary unemployment in times of financial crises; a study on its applicability to the Brazilian socioeconomic specificities and an estimate of their potential target population and of the annual wage cost in the country, as a whole, and in the specific case of the Northeast region and of the state of Rio Grande do Norte.

Geração de renda e ocupações na cadeia agroindustrial de castanha de caju no Rio Grande do Norte: o caso do sertão de Apodi

This work is part of the research group studying agribusiness chains, by characterizing agroindustrial chain of cashew nuts in Rio Grande do Norte, with special emphasis on Sertão de Apodi Citizenship Territory, showing their different flows and linkages and analyzes generating jobs and income in the production of this good, from the experience of COOPAPI, using as a methodology for analyzing the input-output matrix. And this is justified by the fact that Brazil is in the context as the world's fifth largest producer of cashew nuts and the production of this product focus in the Northeast, especially the Rio Grande do Norte, which is the second largest producer of region, behind only the state of Ceará, which is the largest producer in the country. Moreover, in recent years the state has increased its insertion in international markets this product, particularly the Mossoró-Assu Territory, which constitutes the largest producer in the state, particularly the municipality of Serra do Mel, which has an arrangement different yield, based on the model of integrated rural development, embodied in family farming. Nevertheless, the Sertão de Apodi Citizenship appear as the fourth among the Citizenship territories of Rio Grande do Norte in the ranking of the production of cashew nuts, but the prevailing model of Cooperatives in the Territory, based on the Solidarity Economy, i,e, different from the old cooperative, which is based on the precepts as patronage, with cooperative owners, favor, etc.., encourages scientific research. In this, after a careful analysis of data from field research, it was noticed that among the links in the chain, the production link is what generates the most jobs, while the processing link commands to generate income, but a portion meaningful occupations and income are generated outside the territory, especially out of state RN, denouncing the gap in supply of some specific demands within the chain

Formação de educadores de jovens e adultos no Programa Geração Cidadã: relação entre saberes na proposição curricular

This paper deals with the fundamental elements of a curricular proposal aiming at the formation of alphabetizers of young and adults, as long as it concerns the relation between the academic knowledge and that one arising from the classroom experience. The empirical field of the research comes from the work of the teachers responsible for the formation of the alphabetizers of the GerAção Cidadã Program (2004-2005) linked, as an Extension Program, to Federal University of Rio Grande do Norte. Indeed, it tries to understand how these young and adult educators makers figure out the link between the experienced knowledge, which their lives give testimony of, with the scientific knowledge, which they are entitled to mediate in class. This work is funded in the principles of the Collaborative Research, which constitutes a kind of qualitative research. It makes use of procedures supported by qualitative research, especially those ones related to reflexive sessions, as well as to documental researches and semi-structured interviews. These spaces have afforded the group of alphabetizers the opportunity to talk over their practice, not only individually but also collectively, in order to work out contributive proposals having in view changes in the educative actions. As elaborated contributions, we present a discussion about the specificities in the making of educators to EJA, in their differentiated social roles. Reflecting on the experiences of the educators makers, we highlight those elements we regard as essential to the constitution of a formation proposal, like formative times and spaces, dialogue and social memory. The curricular organization is compreneded as part of an enlarged dimension that does not restraint itself to school; rather, it is visualized as a structuring instance that connects different knowledge surpassing community and university. Under this optics, we come to the conclusion that the connection the scientific knowledge establishes with the experienced one, which is immersed in the cultural practices of those who are involved in the formative process, is the basement to a curricular proposal of a formation course destined to educators committed with the need of changing society

Fatores de decisão da adoção do gás natural na geração de energia elétrica em pequena escala em postos de combustíveis: um estudo de anális de decusão usando o processo de hierarquia analítica AHP

A modeling of criterias and alternatives is through and applied a questionnaire based on method AHP to proprietors of gas stations. The considered alternatives had been the maintenance of the current state with electric energy of the deliverer and the generation in small scale based on the natural gas. The used criteria had been Cost of the Investment, Final Cost of the Energy, Operational cost, Ambient Benefits, Risk and Variation of Costs. The study it was carried through in the city of Natal, RN in ranks that make use of the natural as for resale, where the generation alternative on the basis of the available gas is present. The main results evidence in a dimension the viability of use of method AHP with questionnaire by means of validation of the judgments with analysis of variance beyond proper the normal mechanisms of analysis of consistency to the method. The main results of the analysis help to show that in this in case that the profile of models of criteria and judgments of the actors is similar, with the final evidence of that it has a dominance of the maintenance of the energy of the deliverer. The main criterion to influence this decision was the risk

Critérios na tomada de decisão estratégica em projetos de co-geração a gás natural: um estudo em hospitais

This thesis deals with analyzing the actual perception of the brazilian hospital managers about natural gas fired cogeneration. An study of case is developed to obtain information about the viability of the investments in cogeneration technolgies in four hospitals. These studies are made using a questionnaire, to know and to obtain necessaries data of the managers. The main results shows that the investors have a bad feeling about to invest in a different activity. In other hand, the results show that the investors have a good impression about the configuration of the project that uses the project finance like way of financing

CREATION: técnica de criatividade para geração de ideias de novos produtos

Creativity is a skill found in all individuals and one of the strategies used to intensify it is through the application of creativity techniques. In order to propose a new technique for generating new crafts product ideas, this dissertation, which is part of a research project of the Federal University of Rio Grande do Norte, through action research, intervened in three state communities artisans - Lajes Pintada, Massaranduba and Vera Cruz - to develop the artisans creative potential. Based on the techniques studied in the literature, we selected three techniques for interventions, composing two dynamics - one to improve features and functionalities of existing products, with the technique of SCAMPER; and the other to generate ideas for creating new products, with techniques Listing and Random Words / Figures. These latter techniques were not satisfactory in its objective by presenting constraints, not covered in the description, for the participant group. Thus, it was necessary to propose a new technique for the same purpose, the technique CREATION Clarify technique, Realized creativity, Explain, Apply for word, Think fast, Interpret, Organize ideas, Now evaluate, composed of twelve steps. To use the new technique requires that it be used by a dynamic that takes into account three phases: Planning, Application and Analysis. In the new technique application were generated around 30 ideas, regarded as new, in six sessions, from test pilot to interventions in artisans communities

Técnicas de inteligência artificial para a geração dinâmica de set points para uma coluna de destilação

Artificial Intelligence techniques are applied to improve performance of a simulated oil distillation system. The chosen system was a debutanizer column. At this process, the feed, which comes to the column, is segmented by heating. The lightest components become steams, by forming the LPG (Liquefied Petroleum Gas). The others components, C5+, continue liquid. In the composition of the LPG, ideally, we have only propane and butanes, but, in practice, there are contaminants, for example, pentanes. The objective of this work is to control pentane amount in LPG, by means of intelligent set points (SP s) determination for PID controllers that are present in original instrumentation (regulatory control) of the column. A fuzzy system will be responsible for adjusting the SP's, driven by the comparison between the molar fraction of the pentane present in the output of the plant (LPG) and the desired amount. However, the molar fraction of pentane is difficult to measure on-line, due to constraints such as: long intervals of measurement, high reliability and low cost. Therefore, an inference system was used, based on a multilayer neural network, to infer the pentane molar fraction through secondary variables of the column. Finally, the results shown that the proposed control system were able to control the value of pentane molar fraction under different operational situations
