Escravidão na Vila do Príncipe, província do Rio Grande do Norte (1850/1888)

This dissertation presents a study on the slave population of Vila do Príncipe, from 1850 to 1888, based on the judicial and notarial collection of hand written documents as well as on the Reports of Presidents of the Province of Rio Grande do Norte. The issue that drives the research relates to the reproduction of slavery in a region of cattle breeding colonization. Therefore, the research aims to understand how in a peripheral socio-economic place (in Vila do Príncipe, cattle breeding Seridó) after the prohibition of the African slave trade, the slave relationships subsisted and structured themselves. In the sense, the research analyzed the dynamics of socio-economic slave units and their relationship with space, ownership structure and the slave family.

Não há você sem mim: histórias de mulheres sobreviventes de uma tentativa de homicídio

The murder-suicide (H / S) has been defined as a shocking crime in which a person takes the life of another and then kills himself within 24 hours. Set up as a gender violence, because men are in majority, the killers and the women victims. This study aims to understand the meanings of the experience of a H / S, from women who have survived this act. This study sets up as a hermeneutic phenomenological research, based on Heidegger`s ontology. We interviewed three survivors of H / S, whose narratives allowed to approach the senses present in their lives. The interviews were transcribed and interpreted in accordance with the hermeneutic circle, as proposed by Martin Heidegger. From the interviews of research participants perceive that these women have built their senses in stocks, represented the family foundation and the presence of a husband and children. This project that moved their lives toward the construction of modes-of-being. We noticed the presence of historicity constructing meanings for the existence of these women. We found reports of an experience of loving relationships characterized by strong jealousy, with the presence of fantasies of betrayal, and marked by a careful affective relationship that put them in the position of object possession of his companions. Reflect that such caring restricted their existence being-for-husband. So the senses that moved their stocks, which aimed his ways existential, was the creation of a family, a reference to their lives, to live a love, and care for the children. Therefore, beyond the already known aspects in studies on violence against women, which made these women continue to choose this relationship was the sense that they had for their existence. It is hoped that this study will contribute to the construction of a new look on violence against women, taking as a basis the Heideggerian hermeneutic phenomenology

Assentamento Hipólito: realidade e perspectivas dos jovens assentados

Analisa a inserção da população jovem em assentamentos rurais, tomando como referência o Assentamento Hipólito, no município de Mossoró, no Estado do Rio Grande do Norte (RN). O contato com alguns jovens assentados levou à inquietação frente à problemática situação por eles descrita, em relação aos seus cotidianos e às suas perspectivas, o que aponta para o entendimento de que faltam políticas públicas, ou estas não estão sendo adequadas para a população em estudo. As políticas de juventude são, além de recentes, ainda muito escassas; sobretudo, quando se trata da juventude rural. Nessa perspectiva, procura rastrear a trajetória dos jovens no referido Assentamento, visando a uma melhor percepção da inserção social destes na condição de assentados, com a atenção voltada para as suas relações com o seu meio, e com o poder público (local, estadual e federal), as condições de vida, as perspectivas de futuro e as ações governamentais, frente às suas demandas. Os resultados dessa análise apontaram para a ausência de políticas públicas condizentes com a realidade dessa parcela da população, reforçando, mediante a precariedade das condições de vida em que se encontra, o argumento de que a luta pela terra não se encerra com a conquista desta. Pois a consolidação dessa posse vai depender da luta posterior em prol de melhores condições econômicas e sociais. Reforça ainda a necessidade de reconhecer a capacidade potencial dos sujeitos coletivos, na avaliação de seus problemas e necessidades, e fomentar a participação social e política dos trabalhadores, na conquista de seus direitos e na construção de sua cidadania. E ainda que a participação efetiva da juventude é fundamental a qualquer processo de transformação social. Portanto, os jovens rurais são atores inegavelmente importantes quando se pretende entender a dinâmica dos assentamentos rurais no seu contexto maior

Análise da rede política do turismo brasileiro.

The dissertation examines the influence of relationships among actors from Brazilian Tourism Political Network who compose the National Council of Tourism in the drafting of the National Tourism Plans (PNT) - PNTs 2003/2007 and 2007/2010, focusing on two main types of interaction: cooperation and information exchange. Therefore, the study departed from the understanding that the concept of tourism as a human phenomenon is configured as an essential conceptual basis for the development, implementation and analysis of public policies. The application of Network Theory and Social Network Analysis serves as an analytical tool, in addition, the use of concepts of Policy Networks enabled to interpret, in distinct aspects, the social reality of tourism in a more precise and detailed way. The study had a cross-sectional with a longitudinal perspective and case study was adopted, thus enabling to apply the model of social network analysis and qualitative approach. Through the survey conducted, it was found that the drafting process of National Tourism Plans was the result of the interaction of a complex network of actors from public and private initiatives, who compose the National Council of Tourism, and that their power of influence came out simultaneously, but not symmetrically, for both their performance/intervention in the meetings, and the possession of economic and organizational resources. Hence, the establishment of partnerships and information exchanges among the actors were underlying to the PNT drafting process, both in problems perception and insertion in the government agenda, as in making proposals to solve them, thus guiding the construction of large programs and programs contained in both investigated plans.

Análise da deformação pós-Rifte na Bacia do Araripe, Nordeste do Brasil

The Araripe Basin is located over Precambrian terrains of the Borborema Province, being part of Northeast Brazil inner basins. Its origin is related to the fragmentation of the Gondwana supercontinent and consequently opening of South Atlantic during early Cretaceous. The basin has a sedimentary infill encompassing four distinct evolution stages, comprising Paleozoic syneclisis, pre-rift, rift and post-rift. The target of this study comprises the post-rift section of the basin focusing deformational styles which affect evaporates from Ipubi Member of the Santana Formation, which is composed by gypsum and anidrite layers interbedded with shales. These units occur widespread across the basin. In the central part of the basin, near Nova Olinda-Santana do Cariri, evaporites are affected by an essentialy brittle deformation tipified by fibrous gypsum filled fractures, cutting massive layers of gypsum and anidrite. Veins with variable orientations and dips are observed in the region distributed over three main populations: i) a dominant NWSE with shallow to moderate NE dipping population, consisting of gypsum filled veins in which fibers are normal to vein walls; i) NE-SW veins with moderate SE dips containing subhorizontal growth fibers; and iii) N-S veins with shallow E-W dips with fibers oblique to vein walls. In the west portion of the basin, near Trindade-Ipubi-Araripina towns, evaporate layers are dominantly constituted by gypsum/anidrite finely stratified, showing a minor density of veins. These layers are affected by a unique style of deformation, more ductile, typified by gentle to open horizontal normal folding with several tens of meters length and with double plunging NW-SE or NE-SW hinges, configuring domic features. In detail, gypsum/anidrite laminae are affected by metre to decimeter scale close to tight folding, usually kinked, with broken hinges, locally turning into box folds. Veins show NE-SW main directions with shallow NE dips, growth fibers are parallel to vein walls, constituting slickenfibers. This region is marked by faults that affect Araripina Formation with NW-SE, NE-SW and E-W directions. The main structural styles and general orientations of structures which affected the post-rift section of Araripe Basin yielded important kinematic information analysis which led us to infer a E-W to NE-SW extension direction to the northeastern part of the Basin, whereas in the southeastern part, extension occurred in N-S direction. Thus, it was possible to determine a regional kinematic setting, through this analysis, characterizing a NE-SW to ENE-WSW system for the post-rift section, which is compatible with the tension settings for the Sout American Plate since Albian. Local variations at the fluid pressure linked (or not) to sedimentary overload variation define local tension settings. This way, at the northeastern portion of the basin, the post-rift deformation was governed by a setting which σ 1 is sub-horizontal trending NE-SW and, σ 3 is sub-vertical, emphasizing a reverse fault situation. At the southwestern portion however there was characterized a strike slip fault setting, featuring σ 1 trending ENEWSW and σ3 trending NNW-SSE

Fragilidade ambiental da bacia hidrográfica do Rio Punaú (RN) e área litorânea adjacente

Hydrographic basins always exercised a big fascination over humankind that attracted for its scenery beauty or for its richness in natural resources, had been acting in order to modify these important ecosystems without, therefore, considering the possible consequences of these changes. The attributed importance to the coast ecosystems, in eminence to the hydrographic basin of Punaú river and adjacent areas, is had when it s verified the diversity of the ecosystems that contemplate it. Hydrographic basin in evidence in Rio Grande do Norte state, occupies an area of nearly 652.71 km², being it sited in the homogeneous micro-region Litoral Nordeste, with a regional population estimated in nearly 75,188 inhabitants, according to the Anuário Estatístico do Rio Grande do Norte 2004. The region of the researched basin is formed by seven municipal districts related as it follows: Maxaranguape, Pedra Grande, Pureza, Rio do Fogo, São Miguel de Touros, Taipu and Touros, but Maxaranguape, Rio do Fogo, Touros and Pureza have a direct participation in the basin. Basin in study have it lands evaluated according to the agriculturist aptitude by the conventionally methodology practiced in the country, having as objective, then, a compara-tive analysis between the ambient unities, Aeolian littoral and coast tray, identified in the researched area. From the characterization of the physic way of the area in study and owning the kept data, it was proceeded the integrated analysis of the structural elements of the landscape which were evidenced that the fragile areas are associated with the areas of agriculture cultivation, such as the ones of irregular occupation. About the degradation, the ambient diagnostic of the basin indicated that the equivalent to the Aeolian Littoral Ambient Unit correspond to the bigger pledging of the ambient quality, in other words, high ambient fragility, being this result due to the use and occupation of the soil, propitiating this way, vulnerability in the vegetal cover of the area, despite it disposes of a low agriculture cultivation percentage. Already in the Coast Ambient Tray, is emphasized the medium ambient fragility, despite of the high index of cultivated area. In a general way, the total area of the hydrographic basin of Punaú river and adjacent areas presented ambient impacts over the tolerance limit, indicating the necessity of a review of the practices of use and handling of the soil, reforesting of the water courses edges, control of erosion and contamination of the aqueous in the perspective to reduce the effects of the impacts due to the use and occupation of the basin in regard. The present search evaluated the ambient impacts diagnosised in the hydrographic basin of Punaú river and adjacent areas, pointing the causes and the probable consequences of the damages caused by these impacts to the basin ambient. From the analysis of these data, if was possible to become explicit how they are fundamental as key elements in the process of decision taking in the ambient questions

Poéticas do rap engajado e juventudes nas periferias urbanas de Natal-RN

This thesis relates to issues present in the hip hop movement. Thus it includes youngsters grouped in different levels such as local, regional and national. The research deals with this broad segment. The analysis is made on those called “peripheral youth” It encompasses the juvenile segment, that is committed to a movement defined by these youngsters and activists, the so called “hip hop movement”. The research aims to analyze poetics present in rap, considered as an expression of resistance and inventiveness. The analysis was of micro politic nature and it dealt with the “peripheral scenario” present in hip hop Lelo Melodia in the Guarapes neighborhood in Natal-Rio Grande do Norte-Brazil. In this community, the group in known for their resistance attitude. The group´s opinion is not of opposition or force but it is seen in the sense of reinventing life that is currently attached to the persisting social inequality condition. In these terms, the research also deals with this committed poetic rap understood here as expressions towards resistance and inventiveness that is produced by these youth groups that belong to this hip hop movement. The focal group was the Lelo Melodia Group of the Posse de Hip Hop in the Guarapes neighborhood in Natal/Rio Grande do Norte in Brazil.

Simulação da destilação molecular de filme descendente para o petróleo

The heavy part of the oil can be used for numerous purposes, e.g. to obtain lubricating oils. In this context, many researchers have been studying alternatives such separation of crude oil components, among which may be mentioned molecular distillation. Molecular distillation is a forced evaporation technique different from other conventional processes in the literature. This process can be classified as a special distillation case under high vacuum with pressures that reach extremely low ranges of the order of 0.1 Pascal. The evaporation and condensation surfaces must have a distance from each other of the magnitude order of mean free path of the evaporated molecules, that is, molecules evaporated easily reach the condenser, because they find a route without obstacles, what is desirable. Thus, the main contribution of this work is the simulation of the falling-film molecular distillation for crude oil mixtures. The crude oil was characterized using UniSim® Design and R430 Aspen HYSYS® V8.5. The results of this characterization were performed in spreadsheets of Microsoft® Excel®, calculations of the physicochemical properties of the waste of an oil sample, i.e., thermodynamic and transport. Based on this estimated properties and boundary conditions suggested by the literature, equations of temperature and concentration profiles were resolved through the implicit finite difference method using the programming language Visual Basic® (VBA) for Excel®. The result of the temperature profile showed consistent with the reproduced by literature, having in their initial values a slight distortion as a result of the nature of the studied oil is lighter than the literature, since the results of the concentration profiles were effective allowing realize that the concentration of the more volatile decreases and of the less volatile increases due to the length of the evaporator. According to the transport phenomena present in the process, the velocity profile tends to increase to a peak and then decreases, and the film thickness decreases, both as a function of the evaporator length. It is concluded that the simulation code in Visual Basic® language (VBA) is a final product of the work that allows application to molecular distillation of petroleum and other similar mixtures.

Território para viver: dinâmicas territoriais da comunidade quilombola de Acauã, Poço Branco, Rio Grande do Norte

In the late 1980s, the quilombola (or maroon) communities emerged on the Brazilian public scene. They established themselves as new collective subjects and ethnic groups, in a historical moment of sensitive political changes in several social conflicts and struggles, both in Brazil and in Latin America. Because of their socio-cultural and historical singularities, these communities have self-identified in the same collective expression and have organized in search of recognition and respect for their rights. Quilombo communities and other self-labeled as "traditional communities" seek to reaffirm their differences in opposition to a conscious colonizer cultural project and re-signify their memories and traditions, that serve as reference in the construction of alternative production projects and community organization. One of the distinguishing characteristics of this quilombola political emergence process is the territorial nature of the struggles, manifested in at least two directions: on the one hand, the struggle for legal and formal recognition of a given space, i.e., the regularization and titling of occupied territories, considering that the Brazilian Constitution of 1988 recognizes the right of these communities to the final possession of the traditional lands. On the other hand, the struggle for recognition of their territoriality in a broader sense, not necessarily restricted to the demarcated area, but as the recognition of a culture and its own way of life, that originated historically in these territories. The current accomplishments and challenges of the Brazilian quilombola communities are well exemplified by the quilombo of Acauã, in the Poço Branco municipality of Rio Grande do Norte. The last fifteen years have been marked by important changes in this community, which has gained visibility and has emerged as a new political player. Acauã identified itself as quilombola community in 2004, the same year that it formalized its political structure, through the creation of the Association of Residents of Quilombo Acauã (AMQA, in Portuguese). Also in 2004, it requested to the National Institute of Colonization and Land Reform (INCRA, in Portuguese) the opening of the process for regularization and titling of quilombo territory, which is at an advanced stage, but so far without definitive resolution. This study aims to understand the process of territorialization (struggle for territorial claim) played in the last fifteen years by the community of Acauã.

Estimativas, variabilidade e análise de tendência da evapotranspiração de referência em perímetros irrigados, no semiárido do nordeste brasileiro

The variability / climate change has generated great concern worldwide, is one of the major issues as global warming, which can is affecting the availability of water resources in irrigated perimeters. In the semiarid region of Northeastern Brazil it is known that there is a predominance of drought, but it is not enough known about trends in climate series of joint water loss by evaporation and transpiration (evapotranspiration). Therefore, this study aimed to analyze whether there is increase and / or decrease evidence in the regime of reference evapotranspiration (ETo), for the monthly, annual and interdecadal scales in irrigated polo towns of Juazeiro, BA (9 ° 24'S, 40 ° 26'W and 375,5m) and Petrolina, PE (09 ° 09'S, 40 ° 22'W and 376m), which is the main analysis objective. The daily meteorological data were provided by EMBRAPA Semiárido for the period from 01.01.1976 to 31.12.2014, estimated the daily ETo using the standard method of Penman-Monteith (EToPM) parameterized by Smith (1991). Other methods of more simplified estimatives were calculated and compared to EToPM, as the ones following: Solar Radiation (EToRS), Linacre (EToL), Hargreaves and Samani (EToHS) and the method of Class A pan (EToTCA). The main statistical analysis were non-parametric tests of homogeneity (Run), trend (Mann-kendall), magnitude of the trend (Sen) and early trend detection (Mann-Whitney). The statistical significance adopted was 5 and / or 1%. The Analysis of Variance - ANOVA was used to detect if there is a significant difference in mean interdecadal mean. For comparison between the methods of ETo, it were used the correlation test (r), the Student t test and Tukey levels of 5% significance. Finally, statistics Willmott et al. (1985) statistics was used to evaluate the concordance index and performance of simplified methods compared to the standard method. It obtained as main results that there was a decrease in the time series of EToPM in irrigated areas of Juazeiro, BA and Petrolina, PE, significant respectively at 1 and 5%, with an annual magnitude of -14.5 mm (Juazeiro) and -7.7 mm (Petrolina) and early trend in 1996. The methods which had better for better agreement with EToPM were EToRS with very good performance, in both locations, followed by the method of EToL with good performance (Juazeiro) and median (Petrolina). EToHS had the worst performance (bad) for both locations. It is suggested that this decrease of EToPM can be associated with the increase in irrigated agricultural areas and the construction of Sobradinho lake upstream of the perimeters.

A ribeira da discórdia: terras, homens e relações de poder na territorialização do Assu colonial (1680-1720)

The internalization process of the Portuguese possession in Northern Captaincies - after the Dutch eviction and the development of activities related to livestock in the backlands (Sertão) – expanded the Portuguese territory in America. This process resulted in the advancement of Portuguese conquest over the region and conflicts involving agents of colonization and indigenous groups who inhabited that space, as well as conflicts of interest of captaincy’s major social groups and the defense policies of the Portuguese territory possession. Among the rivers which run through Rio Grande captaincy’s territory, the Açu was the one that aroused conquerors and colonizers of the back lands interest, making that spatiality an area where interest and power exercises converged and generated discord. This research aims to analyze the territorial process of Assu backlands, from the pioneers, conquerors and colonizers action over the space studied, during the event known as the War of the Barbarians in Assu, conflict that ensured the integration of the area the territory and the wishes of the Portuguese crown. Thus, it will be taken as objects of study social phenomena that characterized Assu’s riverside - at the turn of the 17th to the 18th century, in a cutout that extends from 1680 to 1720 - as an area of conflicts of interest, noticeable for analysis from period documents such as records of land grants concessions, correspondence between colonial and kingdom authorities, documents from the exercise of administration of Portuguese America and legislation.

Modelagem multiescala de fenômenos eletrocinéticos em meios porosos carregados eletricamente: aplicação a meios porosos argilosos

In this master thesis, we propose a multiscale mathematical and computational model for electrokinetic phenomena in porous media electrically charged. We consider a porous medium rigid and incompressible saturated by an electrolyte solution containing four monovalent ionic solutes completely diluted in the aqueous solvent. Initially we developed the modeling electrical double layer how objective to compute the electrical potential, surface density of electrical charges and considering two chemical reactions, we propose a 2-pK model for calculating the chemical adsorption occurring in the domain of electrical double layer. Having the nanoscopic model, we deduce a model in the microscale, where the electrochemical adsorption of ions, protonation/ deprotonation reactions and zeta potential obtained in the nanoscale, are incorporated through the conditions of interface uid/solid of the Stokes problem and transportation of ions, modeled by equations of Nernst-Planck. Using the homogenization technique of periodic structures, we develop a model in macroscopic scale with respective cells problems for the e ective macroscopic parameters of equations. Finally, we propose several numerical simulations of the multiscale model for uid ow and transport of reactive ionic solute in a saturated aqueous solution of kaolinite. Using nanoscopic model we propose some numerical simulations of electrochemical adsorption phenomena in the electrical double layer. Making use of the nite element method discretize the macroscopic model and propose some numerical simulations in basic and acid system aiming to quantify the transport of ionic solutes in porous media electrically charged.
