Retratos do cotidiano: as mulheres do assentamento rural Santa Vitória

The present work shows trajectories of life of seated women agricultural, with the objective to apprehend on aspects to the experience of its sexuality. The daily one of the seated woman is constructed in a new space, called agricultural nesting whose formation if presents with proper singularity to a social and economic context and politician of the Great River of the North. Its passages of life are permeaty by different violences suffered in its daily one and its sexuality is weaveeed by a set of rules that the naturalization of the subordination of the woman in relation to the man keeps. The societies use the systems of the relations between men and women and transform the biological characteristic into activities human beings

As mudanças da educação do RN nos idos de 1950 e 1960 :a prática de Lia Campo

The present study investigates and analyzes the participation of the teacher Lia Campos, during the 50 s and 60 s years, in the norte-riograndense educational organization. The choice of the period is justified because was at this the time what this teacher remained in the potiguar lands, working in favor of the education. In the search of data that informed me concerning her actions, I cover quantities as the Public Archive of the Great River of the North, Historical Institute and Geographic of the Rio Grande do Norte and the Center of Supplementary Studies Teacher Lia Campos, in the task to obtain photographs and verbal stories of friends and fellow workers, periodicals of the time, laws and decrees. Based on the primary education, the work of Lia Campos shows the relevance of the teaching formation for this level of education and the way as the ones that in it work can lead their conceptions and daily practical tasks. This way, I evidence that the cited teacher promotes, in this State, a series of activities as: survey and systematization of the school net; organization of the administrative stuff of the schools; qualifications and courses of improving for lay professors, as well as implantation of the Law of the Education nº 2.171/1957. Through this analysis I show as this teacher left printed her mark in the Rio Grande do Norte historiography by means of her actions, being therefore remembered for that they had followed her experience in norte-riograndense lands

Construção e avaliação térmica de um fogão solar tipo caixa

The present work presents a contribution in the study of modelings of transference of heat for foods submitted to the experimental tests in the considered solar oven, where the best modeling for the beefburger of chicken in study was evaluated, comparing the results, considering this food as a half-infinite(1er object considered model) and,after that, considered the chicken beefburger as a plain plate in transient regimen in two distinct conditions: not considering and another model considering the contribution of the generation term, through the Criterion of Pomerantsev. The Sun, beyond life source, is the origin of all the energy forms that the man comes using during its history and can be the reply for the question of the energy supplying in the future, a time that learns to use to advantage in rational way the light that this star constantly special tax on our planet. Shining more than the 5 billion years, it is calculated that the Sun still in them will privilege for others 6 billion years, or either, it is only in the half of its existence and will launch on the Earth, only in this year, 4000 times more energy that we will consume. Front to this reality, would be irrational not to search, by all means technical possible, to use to advantage this clean, ecological and gratuitous power plant. In this dissertation evaluate the performance of solar cooker of the type box. Laboratory of Solar Energy of the Federal University of the Great River of North - UFRN was constructed by the group (LES) a model of solar stove of the type box and was tested its viability technique, considering modeling foods submitted when baking in the solar oven, the cooker has main characteristic the easiness of manufacture and assembly, the low cost (was used material accessible composition to the low income communities) and simplicity in the mechanism of movement of the archetype for incidence of the direct solar light. They had been proposals modeling for calculations of food the minimum baking time, considering the following models of transference of heat in the transient state: object the halfinfinite, plain plate and the model of the sphere to study the necessary temperature for the it bakes of bread (considering spherical geometry). After evaluate the models of transmission of heat will be foods submitted you the processes of to it bakes of, the times gotten for the modeling with the experimental times of it bakes in the solar oven had been compared, demonstrating the modeling that more good that it portraies the accuracies of the results of the model

Sitios geologicos e geomorfologicos dos municipios de Acari, Carnaúba dos Dantas e Currais Novos, região saridó do Rio Grande do Norte

Geological and Geomorphological Sites of the Towns of Acari, Carnaúba dos Dantas and Currais Novos, Seridó Region of the Rio Grande do Norte, northeastern Brazil, consist s of a study about geological, geomorphological, mineralogical, palaeontological and archaeological features of the study area, aiming the identification of sites that presents scientific, historical, cultural, economic and ecological excellent importance, and that they deserve to receive special protection for its maintenance for the gifts and future generations. It was developed according with methods adopted for the Brazilian Commitee of Geological and Paleontological Sites SIGEP/UNESCO and by Initiati ve of Sofia for the Preservation of the Mineral Diversity of the Planet, objectifying the description of the main sites, the its environmental problematic and proposal of protectionistic measures. Seven sites with features and typical structures had been identified that they deserve to be aim of protection. In the Acari town, three sites had been identified: geological -geomorphologicalarchaeological site Barra of the Carnaúba; geological-geomorphological site of the Gargalheiras; and geological-geomorphological site Bico of Arara. In Carnaúba of the Dantas, the geomorphological complex river of the Bojo that possesss canyons and deep throats, with rocky-arts registers of the three great rocky-arts traditions of northeast: Northeast Seridó Sub-tradition, Wasteland and Itaquatiara. In the Currais Novos town, 3 sites had been also identified: geomorphological site Canyon of the Apertados; geomorphological-archaeological-palaeontological complex of the Totoró; e, geologicalmineralogical site Brejuí. Because to the environmental problematic that it involves each one of the identified sites, it is proposed, as a guarantee of protection to these sites, its economic exploitation with the ecogeotouristic activity, that it aims at to the integration of the community in programs of environmental education and others, besides providing to the generation of job and income for the towns. Finally, a series of measures is suggested that they aim at to the efectivation of the activity and to the protection of the sites that they can be classified as natural heritage, in accordance with the denomination of UNESCO, in its program World Natural Heritage

To investigate the possibilities and limits of mechanisms of participativa management in the scope of the Pronaf - National Program of Fortalecimento of Familiar Agriculture, and the corresponding effectiveness of its actions in the construction of alternatives of sustainable agricultural development in the Coast North of the State of the Great River of the North, more specifically, in the composed Subzona de Touros for the cities of Bulls, White Well, Pureness, Is Miguel of the Gostoso and Taipu. To carry through this analysis they had been carried through Research of Field with the objective to reconstitute the trajectory of the CMDRS, to trace the profile of the citizens that compose each one of the five advice, its expectations, interests and the level of participation of the local population

Zoneamento geoambiental como subsídio ao planejamento territorial municipal: estudo de caso para Currais Novos/RN

This paper presents the master plan and geoenvironmental zoning natures as instruments of environmental planning and management. The discussion of territory environmental planning is guided by two directions: at first the environmental elements involved in planning and the another is the implementation of these instruments at the municipal territory. To analyze the planning directed of the municipal territory we consider the fragments of its, represented by country and urban. The master plan inside of the Estatuto da Cidade (City Statute) and the geoenvironmental zoning are directed to territorial environmental planning. Regarding of the master plan the first challenge has been the spacial area that the plan can cover. It is necessary to prepare master plans that could include all the territory. The environmental zoning are directed for the territory totality.In this sense, the geoenvironmental zoning of the Currais Novos was done in the totality of the municipal territory and guided by the environmental physics variables. The geoenvironmental zoning sets in a planning and ordering of the territory instrument based in the landscape analysis. Therefore grounded in the Geosystems‟s Theory this work has like a main objective to propose a geoenvironmental zoning for the Currais Novos Municipality in RN. So, was used an analysis technique suggested for Bardin (2010) and the Currais Novos‟s physical environment characterization through of the fieldwork and cartographic data vectorization, beyond the image‟s treatment SRTM. The geoenvironmental systems definitions were based in the suggestion of Cestaro, et al. (2007) support in Bertrand (1968). For both were identified five geoenvironmental systems: Borborema Plateau, Residual plateau, Chapada da Serra de Santana, semiarid river valley and lagoon valley and eleven geoenvironmental subsystems: Borborema Plateau Western Slope, Isolated Massif of the Borborema Plateau, Residual Crest, Residual Massif, Erosional Scarp of the Chapada, flat top plateau, fluvial plains, temporary river of the semiarid and ornamental water or sluice

Aquisição, processamento e análise de dados de sísmica de alta resolução na plataforma continental norte do Rio Grande do Norte: Vale inciso do rio açu

On the modern Continental Shelf to the north of Rio Grande do Norte state (NE Brazil) is located a paleo-valley, submerged during the last glacial sea-level lowstand, that marks continuation of the most important river of this area (Açu River). Despite the high level of exploration activity of oil industry, there is few information about shallow stratigraphy. Aiming to fill this gap, situated on the Neogene, was worked a marine seismic investigation, the development of a processing flow for high resolution data seismic, and the recognition of the main feature morphology of the study area: the incised valley of the River Açu. The acquisition of shallow seismic data was undertaken in conjunction with the laboratory of Marine Geology/Geophysics and Environmental Monitoring - GGEMMA of Federal University of Rio Grande do Norte UFRN, in SISPLAT project, where the geomorphological structure of the Rio paleovale Açu was the target of the investigation survey. The acquisition of geophysical data has been over the longitudinal and transverse sections, which were subsequently submitted to the processing, hitherto little-used and / or few addressed in the literature, which provided a much higher quality result with the raw data. Once proposed for the flow data was developed and applied to the data of X-Star (acoustic sensor), using available resources of the program ReflexW 4.5 A surface fluvial architecture has been constructed from the bathymetric data and remote sensing image fused and draped over Digital Elevation Models to create three-dimensional (3D) perspective views that are used to analyze the 3D geometry geological features and provide the mapping morphologically defined. The results are expressed in the analysis of seismic sections that extend over the region of the continental shelf and upper slope from mouth of the Açu River to the shelf edge, providing the identification / quantification of geometrical features such as depth, thickness, horizons and units seismic stratigraphyc area, with emphasis has been placed on the palaeoenvironmental interpretation of discordance limit and fill sediment of the incised valley, control by structural elements, and marked by the influence of changes in the sea level. The interpretation of the evolution of this river is worth can bring information to enable more precise descriptions and interpretations, which describes the palaeoenvironmental controls influencing incised valley evolution and preservation to provide a better comprehensive understanding of this reservoir analog system

Gerenciamento ambiental das fazendas de camarão do Rio Grande do Norte

The present dissertação had as objective to study the ambient management in the Farms Saint Rita, Tahim Agropesca and Agropesca Rigomoleiro, in the Great River of the North. For this we use as theoretical tool some fundantes concepts of geographic science, the space, and as concepts auxiliary of ambient management, of estuaries as the half natural one and of manguezais as ecosystem. The study if it gave taking in consideration a model of flow of activities of a typical farm following the way of the residues produced since the beginning until its final destination, in a suitable script of SCHERER (1999). The considered flow established a sequence activities where it is identified the material of entrance, the process of management, the residues of exit and the destination of the residues to the long one of the phase of culture of the shrimp. From it was there had been elaborated a series of managemental pictures with the data raised in the three farms, of different transports and concludes that the ambient management of these farms does not follow the formal standards of a system of typical ambient management. Collating with the system of considered by norm ISO14000 the study it disclosed that all the companies are in a situation of not conformity and that the impacts on the environment continue being many significant ones. However, it is possible to implant norm ISO14000 because some procedures implanted for the farms are correct of the point of view of the ambient management

Expressão heteróloga de biossurfactantes identificados em bibliotecas metagenômicas

The microorganisms have a vast genetic diversity and they are present throughout the biosphere, however, only about 1% of the species can be cultivated by traditional cultivation techniques. Within this diversity there is a huge pool genetic and biological being explored. The metagenomics has enabled direct access to microbial genome derived from environmental samples using independent methods of cultivation. The methodology enables to obtain functional information about the proteins, as well as identify potential products with biotechnological interest and new industrially exploitable biological resources, such as new solutions to environmental impacts. Oil-contaminated areas are characterized by a large accumulation of hydrocarbons and surfactants may be used for bioremediation. Thus, the metagenomic approach was used in this study in order to select genes involved in the degradation and hydrocarbon emulsification. In a previous work, the environmental DNA (eDNA) was extracted from soil samples collected from two different areas (Caatinga and Saline River) of Rio Grande do Norte (Brazil), the metagenomic libraries were constructed and functionally analyzed. The clone able to degrade the oil was evaluated for the ability to synthesize biosurfactants. The sequence analysis revealed an ORF with 897 bp, 298 amino acids and a protein with around 34 kDa. The search for homology in GenBank revealed sequence similarity with a hypothetical protein of representatives Halobacteriaceae family, who were recently shown as strains producing biosurfactants. The presence of the inserted coding sequence and the acquired phenotype was confirmed. Primers were designed and the ORF amplified by PCR. The ORF was subcloned into pETDuet-1 expression vector for subsequent purification of the protein of interest containing a histidine tail. The tests performed to confirm the biosurfactant activity and the ability of hydrocarbon degradation showed positive results. The immunodetection test (western blot) using the monoclonal AntiHis® confirmed the presence of the environmental protein. This study was the first to report a possible protein with biosurfactant activity obtained from a metagenomic approach

Turismo rural no Rio Grande do Norte: desafios e perspectivas

The Rural Tourism appears as an economic alternative to the agricultural way, having to base itself on the revaluation of the local resources, as well as must be implemented through the local agents, a tourism of communitarian base. In this perspective the present objective work to analyze of that it forms if configures the tourist activity in the agricultural space of the Rio Grande do Norte, which the challenges and perspectives faced for the development of this activity. On the basis of this approach searched to argue on the deep transformations that the rural space comes suffering, with insertions of activities not-agriculturists, alternative for the effect of the economic reorganization, as well as on the public politics come back toward the Rural Tourism and an analysis concerning the activities of Rural Tourism that the Rio Grande do Norte comes developing and as this if it presents. As it arrives in port theoretical, we use the Concept of Territory, according to Saints, this if it makes pertinent in the conflicting analyses of the agricultural space for inside to embody of its conceptual picture the territorial dynamics substantiated by the relations politics, economic, social and cultural, where in them it made possible one better analysis in this process. As methodology bibliographical survey was used, in periodic, digital books, documents and interviews in some governmental spheres. The Great River of the North was evidenced that, signals for the development of the agricultural Tourism, therefore the state if presents with a gamma of potentialities, identified and developed some already being through some projects, however if it makes necessary a bigger involvement of all the spheres, considered basic so that this activity can be consolidated as plus a tourist segment in the RN.
