A céu aberto: garimpando a memória e a identidade dos mineradores de Brejuí

The Brejuí Mine, situated in the municipality of Currais Novos (RN), was responsible for the local economy growth between the years of 1943 and 1990, causing the interest of miner's working class to its urban center. After the end of scheelita extraction, the mine became a "theme park", in 2004. The company left its mark on the city by building several monuments in reference to the mining activity and the company's founder, Tomaz Salustino. However, there are no written records that describe such activities on its early years, nor their pioneers in the mining subject. Therefore, it is important to investigate the miner’s memories and ask if, along the more than five decades that lasted the heyday of mining, an identity linked to the profession was built; the extent to which workers make reference to this history as membersand what are the symbols that are being triggered in the development of a working class identity. Further, I investigate what memory was mad concerning the pioneers, mostly farmers attracted by miner work. To do so, I make use of audiovisual archival resources and oral records of the interlocutors that were filmed in the preparations of the documentary “Lembranças de velhos garimpeiros". We have noticed that, in the script of the official history of the Brejuí Mine, the "boss" figure overlaps the workers and that the forms patronage, originated from the rural world, followed punctuating the social relations in the mine. Today, with the resumption of the mining activity, it is possible that the strengthening of the working class and the Seridó miner identity desire reborn.

Capital social e desenvolvimento de territórios: estudo multicasos nos territórios da cidadania do Rio Grande do Norte

This study aims to systematize elements for territorial development analyzing attributes of social capital present in the territories of Rio Grande do Norte. Unlike other studies about the subject, it is not intended to measure the stock of social capital, but rather to reveal the phenomenon of social organization and its implications, considering territories examined are already made around social capital structures. Case study were used as strategy research because it is enables to understand holistic features and significant events within the context of real life. For this research were selected representatives of public and social institutions involved in territorial collegiate specifically those of the governing core, selected from the more effective involvement of discretion in structure, functioning and meetings. The three territories have similar realities, are products of a public policy that is based on common criteria and present interdependence between categories of analysis of social capital. The presence or absence of any relationship - link, bridge or connection - influences the performance of territorial policy, affecting the social organization and fostering processes of access to information. In the cases at hand, despite the similarity of the general conditions of structure and function, the Apodi has qualities superior to the other. The presence of Dom Helder Camara project that articulates, in parallel to the Territory of Citizenship, the same actors of public policy with social mobilization capacity and effectiveness of actions, is able to encourage different development processes at Apodi. This can be explanatory factor, the tangent construct social capital, so that the territory present living conditions and better levels of development than the other two addressed here.

Spondias tuberosa Arr. (UMBU): estudo fitoquímico e avaliação do potencial anti-inflamatório

Spondias tuberosa Arruda (Anacardiaceae) is a fruitful tree popularly known as umbuzeiro, tapereba or umbu. It is a native and endemic species from Brazil, widespread in Brazilian Northeast. The species is important in folk medicine of the semi-arid Northeast, where it is mainly used to treat various inflammatory conditions, digestive problems as well as viral and bacterial infections. However, despite the common use in folk medicine, there are scarce pharmacological and phytochemicals studies that afford scientific evidence to its popular use. Therefore, this study aimed to characterize the chemical markers in S. tuberosa leaves extract, obtained by maceration ethanol:water (70:30, [v/v]), and evaluate its anti-inflammatory potential in vivo. The phytochemical profile in TLC analysis suggested the occurence of the flavonoids rutin and isoquercitrin. HPLC analysis enabled us to confirm the presence of flavonoids and also, were detected the phenolic acids, chlorogenic acid and caffeic acid. In addition was developed and validated a HPLC method to evaluate the content of the identified compounds in S. tuberosa leaves extract according to RDC 899/2003 of ANVISA and ICH Guidelines 2005. In order to evaluate the anti-inflammatory potential of S. tuberosa leaves extract, the peritonitis and paw edema models induced by carrageenan were used, administration i.p. in mice. The results highlighted the anti-inflammatory property in vivo at 125, 250 and 500 mg/kg since a decrease in leukocyte influx to the site of inflammation, diameter of the edema and the level of myeloperoxidase were observed when compared to the drug control dexamethasone (2 mg/kg, i.p. route). Taken together, the results pointed out S. tuberosa as a potential species for developing phytotherapic derivatives in according to its popular use. With regard to the characterization markers, chlorogenic acid, caffeic acid, rutin and isoquercitrin were identified and quantified in Spondias tuberosa leaves extract so they could be used in quality control analyses of the raw material and extracts of this species.

Zoneamento agroclimático da palma forrageira (Opuntia sp.) para o estado da Paraíba

The cactus pear has become over the years an important forage alternative for brazilian semiarid region, especially during long periods of drought. Despite its importance for agriculture, its cultivation has dispensed basic crop practices and fundamentals technical-scientific basis about its climatic requirements. Thus, the main objective of this study was to elaborate the agroclimatic zoning of cactus pear (Opuntia sp.) for the state of Paraíba. The agroclimatic zoning of cactus pear was based on climatic indicators outlined in the literature and climatological data of precipitation and temperature (mean, maximum, and minimum) from 97 locations in the state of Paraíba. According to the results, the region of ‘Borborema’ is the most favorable for the cultivation of cactus pear. The regions of ‘Agreste’, ‘Sertão’, and coastal part of Litoral may be used but with restrictions. However, the cultivation of cactus pear is recommended throughout the state of Paraíba, except the coastal part of the Litoral and the region around Areia. In both cases, the inability is due to excessive precipitation.

Parasitos de importância para a caprinocultura e a ovinocultura potiguar

The goat and sheep industry shows up as an agricultural activity of great importance for the semiarid Northeast. However, the sheep and goats production is made with various difficulties. Among them, parasitic infections, particularly helminth infections of the gastrointestinal tract, the eimeriosis and toxoplasmosis; this one related to problems in reproduction. For this reason, the aim of this study is to to make a survey of the occurrence and some determinants of parasitic diseases that affect small ruminant flocks of the microregions Natal, Macaíba, Litoral Sul, Angicos, Vale do Açu and Borborema Potiguar. Thereunto, epidemiological tools were applied with producers, keepers or guardians of herds and also held collections of blood and feces of animals in eight properties located in seven municipalities of these microregions. The parasite load of the animals was determined through eggs and oocysts counting per gram of feces EPG and OPG, respectively. In addition, the recovery of infective larvae was made. Blood samples were used to measure the globular cell volume and the search for anti-Toxoplasma gondii IgG in sheep serum, by Enzyme Linked Immune Sorbent Assay (ELISA). For categorical variables, the statistical analysis was performed using Poisson regression, with significance level of 0.05. The analysis of the instruments showed that ivermectin is the anthelmintic used in 85,71% of properties. From the total of feces samples of the sheep (n = 179), 53,07% were positive for helminth eggs and 48,04% were positive for oocysts of Eimeria. From the samples of faeces of goats (n = 133), 72,18% were positive for helminth eggs and 96,99% for oocysts of Eimeria. The lowest EPG and OPG count was observed in the micro region of Angicos. Most of the EPG count was found in the micro region Litoral Sul and the OPG count in the micro-region Borborema Potiguar. Both cases the difference was statistically significant(p- value0,000)The most prevalent helminth genus found was Haemonchus, present in 49,87% of the sheep and 80,42% of goats. The average of hematocrit ranged from 22,91 to 33,25 in sheep and from 22,62 to 28,25 in goats. The prevalence of anti-Toxoplasma gondii IgG ranged from 63,33% to 100,00%. The goats showed to be more susceptible to infections by parasites of the gastrointestinal tract than the sheep. In all the properties was observed high prevalence of infection by T. gondii, with the lowest percentages recorded in the micro regions Angicos and Borborema Potiguar.

O figurino na narrativa dos filmes de Guel Arraes: O Auto da Compadecida (2000) e O Bem Amado (2010)

This research focuses on the course of Guel Arraes, moviemaker, and picks two movies for analysis: O Auto da Compadecida (2000) and O Bem Amado (2010), as well as their costumes. The focus on the costume is based on Semiology and aims to decode the meanings that stem out of the clothes. Three of the movies characters will have their costumes analyzed based on Roland Barthes’ theory, mainly considering semiology elements (language and speech), (significant and meaning) and (system and syntagma). The influence of the Armorial movement into the movie O Auto da Compadecida and the Kitsch aesthetic in O Bem Amado deserve consideration, aside from the study on costumes function within narrative, supported by Roland Barthes’ structural analysis of the narrative. We sought to highlight the balance between characters’ lines and the image of the costumes in the movies. Adding to the study on how costumes strongly accounts to narrative, we observed characteristic traits of director and scriptwriter Guel Arraes present in his works, which are the northeastern man identity, a presentation of the Northeast and popular comedy. We believe that his choices when creating and his life influences are not separate from one another. Our research was movie-appraisal centered and had a thorough investigation all over language. The main considerations are supported by the following theories: Barthes (2007), Figueirôa and Fechine (2008), Moles (2001), Stuart Hall (2005) and Mikhail Bakhtin (2013).

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.

Ser-tão de Buriti: o corpo de noturno rumor (a poética de Guimarães Rosa e o pensamento literário contemporâneo)

This thesis is to analyze the fictional texture of Buriti, novella by Guimarães Rosa, which makes part of Corpo do Baile. Gilles Deleuze‘s philosophical background as well as similar theorists such as Mircea Eliade, Derrida, Bataille, Foucault, Blanchot and Nie-tzsche constitute the main reference, as example of Guimarães Rosa‘s problematizing writing, since they present as basic element of thought the desterritorialization of con-cepts, standards and institutionalized knowledge by the dominant literary language. Along with the theoretical perspective of current alterity on these authors, Buriti is crossed by one aesthetics substantiated with a multiplicity of narrative points of view, opening gaps to other non-sacralized, nomadic voices, using polyphony as a way of breaking and destabilizing crystallized truths related to the canons of mother tongue. Interwoven by a poetic side of transgression, the narrative of Buriti finds especially marked by the signs of the backlands and of the night, which rhizomatically point to a sense of infinity, eternity, loneliness, vertigo before the abyssal, evoking the singularity of a ser-tão before the night, "the body of nocturnal rumor." The nights in the backlands in Buriti give rise to the emergence of a state of subjectivity, the ser-tão, whose nature is shown as a space of communion of the various beings that humans put on the same level of other living beings, setting up a sharing cosmic territory, enjoyment between pain and pleasure, between death and life. It is the night in the darkness, the shadows, the ser-tão is exposed, the being in his depth, facing himself with his internal rumors, which project themselves through the noise, the sound amplified by the vastness of the night at the desert backlands. "The backlands is the night." (ROSA, 1988, p.92).

Nego veio é um sofrer : uma etnografia da subalternidade e do subalterno numa irmandade do Rosário

The object of this work is a fellowship of São Sebastião e Nossa Senhora do Rosário in the city of Jardim do Seridó (RN), that is, a black catholic fellowship on the sertão potiguar. The devotion to Nossa Senhora do Rosário, in colonial Brazil, organizes itself through black catholic men as fellowships. They blossomed in Brazil until the abolition, getting support from the Catholic church, from owners of slaves and from the population in general − unlike others afro-Brazilian religious expression. Today, these fellowships remain active, against the sentimental pessimism of the folklore studies, and they also have a highlight position in the calendar of many cities in Brazil, and in particular in Seridó. The research s foothold is the apparent valorization of the fellowship by the local elite, attitude that hides asymmetric relationships between the group of negros do Rosário and the local authorities, having as its consequence that the members occupy a subaltern position inside their own fellowship. This subalternity take place, mainly, in the public area, where the negros do Rosário cannot represent themselves neither political nor discursively. To discuss this idea, it s done a brief historical of these catholic institutions as well as a description of the relationship between the negros do Rosário and the elites of the city. Then, the phenomenon is analyzed as folklore and/or religion , under the perspective of many agents that participate in this process. In other moment, it is going to be presented how the group formulates their own representation of the history, of the devotional forms and of their own political-religious experiences. In this sense, an ethnography of the subalternity is understood as an analysis of the process that leads the negros do Rosário to become a subaltern group. It s also outlined the perception that the group has of its own position, through an ethnography essay of the subaltern subject. The research, focused in the group of Rosário, was done between August 2010 and January 2012 and includes other agents (like treasurers, priests and intellectuals). Besides that, as a methodological complement, there are documental research, photography, as well as shoots of the party days and public presentation

Povoações, freguesias e vilas na Paraíba Colonial: Pombal e Sousa, 1697-1800

The towns presently named Pombal and Sousa, located in the hinterland of the State of Paraíba, Brazil, still keep vestiges of the colonization process they went through along the 18th and 19th centuries, when they both emerged as settlement nuclei in the extreme West of the then captaincy of Paraíba and attained the status of freguesia and vila in a later period. This research aims to comprehend the process of urban formation and development of the colonial urban nuclei of Pombal and Sousa as they became povoados (hamlets), freguesias (parishes) and vilas (small urban communities with a local government), according to territorial expansion policies implemented by the Portuguese government from 1697 to 1800. The choice of the two urban settlements for this survey lies in the fact that they were part of the great conquest and colonization program undertaken by the Portuguese Crown. Another aspect that was considered was the fact that those towns are the oldest urban nuclei of Paraíba s hinterland. They came into being as early as in the times of the colony, thus producing a favorable environment to the study of the changes that occurred in the captaincy s hinterland scenery resulting from the process of formation and development of the colonial urban space. Three fundamental categories of analysis were defined since they have a direct bearing upon the urban configuration of the two colonization nuclei: povoado, freguesia and vila. The three of them are related to civil and ecclesiastic jurisdictions. Field, documentation and bibliography surveys were undertaken in order to develop the study. They allowed for the finding of vestiges of the old, colonial urban structures and for the development of theoretical analysis based on present-day studies of issues relating to the colonial urban history. The study purposes were, therefore, to try to understand how the old urban nuclei of Pombal and Sousa fit in the territorial expansion policies undertaken by the Portuguese government; to relate the process of urban formation and development of such nuclei with the categories of analysis povoação-freguesia-vila by discussing the relations and influences they exert over one another and their territory, as well as to unveil, as much as possible, the configuration the urban spaces that were shaped along the 18th century

Contra as Secas: a engenharia e as origens de um planejamento regional no nordeste brasileiro

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

Efeito da adição de fibras da palma do licuri (syagrus coronata) no comportamento físico e mecânico de compósitos de matriz cimentícia

This research was motivated by the requirement of asbestos s replacement in building systems and the need to generate jobs and income in the country side of the state of Bahia, Brazil. The project aimed at using fibers from licuri leaves (syagrus coronata), an abundant palm in the region, to produce composites appropriate for the sustainable production of cement fibre reinforced products in small plants. The composites were produced in laboratory using Portland cement CP-II-F32, sand, water, licuri palm fiber contents of 1.0, 1.5 and 2.0% by weight of binder (two different fiber length) and metakaolin. The latter was chosen as an additional binder for its efficiency to reduce the alkalinity of cementitious matrixes therefore preventing the degradation of vegetable fibers. The characterization of the composite components was carried out by sieving and laser particle size analyses, thermal analysis, fluorescence and X-ray diffraction. The composites performance was evaluated by 3- point-bending tests, compressive strength, ultrasound module of elasticity, free and restrained shrinkage, water capillarity absorption and apparent specific gravity. It has been found that the addition of fibers increased the time to onset of cracking over 200.00% and a 25% reduction in cracks opening in the restrained shrinkage test. The capillary absorption reduced about 25% when compared to fiber-free composites. It was also observed with regard to flexural strength, compressive strength and specific gravity, that the addiction of fibers did not affect the composite performance presenting similar results for compounds with and without fibers. In general it can be stated that the reinforced composite fibers of palm licuri presents physical and mechanical characteristics which enable them to be used in the intended proposals of this research
