A arte rupestre como expressão comunicativa da cultura

Along their existence, through of the millenniuns, the Man registers, one way or another, their saga. One in those registration ways is the rupestrian art. Through the rupestrian art the Prehistory is brought even us, portraying in images the daily ritualist and magic of the Man, in scenes that show, among other, their cults and also their daily hard work. The Man is imposed, while registering of their existence, starting from the moment in that he is capable to leave their marks through the transformation that attributes to the Nature; also for the produced interferences and for the cultural singularities that themselves were constituted before the period of the alphabetical writing. In an artifice of duplicating utensils and in the sense of representing animals and to himself own, he delegated us a communicative system whose contexts and details were - and it continue being - an enigma to be deciphered. Starting from this argument, the research has for objective to understand the daily and the history of cultural groups that they preceded us, taking as base the reading of the rupestrian paintings found at the located archeological ranches in the Area of Seridó, more specifically in the Complexo Xique-xique, close to the Municipal district of Carnaúba dos Dantas, distant 220 kilometers of Natal, the capital of Rio Grande do Norte State

Habitus, representações sociais e construção identitária dos professores de Maracanaú

In the last three decades, the subject of the teacher's social identity has been discussed under various theoretical focuses, not only in Brazil, but also beyond our borders. In this thesis, the theme is approached starting from the theoretical proposal that has been developed by Domingos Sobrinho (1994), which is strongly based in the epistemological approach between Pierre Bourdieu’s praxiology and the Theory of the Social Representations formulated by Serge Moscovici. It presupposes that this would make it easier to apprehend the process of construction of social identity of the investigated social group. The universe of the research is constituted by teachers of the fundamental teaching of the municipal district of Maracanaú, state of Ceará, that were active in class-room work there during at least three years, and were registered or had concluded the Course of Educational Formation promoted by UECE in that municipal district. Taking into account that the teacher's social identity is a process in permanent construction, resulting of their daily experiences and of the interferences originated from of the social context, the investigative tasks were implemented in two different stages, although they complement each other. Initially, with the objective of putting in evidence the genesis of the formation of that group’s habitus, an analysis of the family and school lives of eleven teachers who participated in the course was made, using as main sources of data: thematic memorials, semi-structured interviews and observations - inside and out of the class-room – during four school semesters. In the second stage a test of free association of words was applied to 426 teachers, seeking to apprehend the structure of the social representations of family and school – a methodological strategy considered necessary to enhance and identify certain outlines of the habitus in study, besides being in agreement with the theoretical model followed. It became evident from the results that the identity of Maracanaú’s teachers is molded and transformed into a multifaceted dynamic unit that shows successes and mistakes, certainties and doubts. For instance, besides an innovative speech seeking to reassure that teaching is a profession and not a simple vocation or mission, some discourse and attitudes are identified that point to the opposite direction, extolling the school as extension of the family, defending a parental relationship with the students, and looking at certain aspects of daily school life as “sacramental”. However, in the light of science such ambiguities and incoherences are inherent to common sense discourse, where the influences of the patterns and cultural references are present in the process of identity construction of the group, which was confirmed by the research of their social representations of family and school

Utilização do controle estatístico do processo para monitoramento do peso médio de cápsulas de Tuberculostáticos: estudo de caso no NUPLAM- RN

This Master Thesis presents a case study on the use of Statistical Process Control (SPC) at the Núcleo de Pesquisas em Alimentos e Medicamentos (NUPLAM). The SPC basic tools have been applied in the process of the tuberculostáticos drugs encapsulation, primarily concerning the objective to choose, between two speeds, which one is the best one to perform the tuberculostatics encapsulation. Later on, with the company effectively operating, the SPC was applied intending to know the variability of the process and, through the tracking of the process itself, to arrive at an estimated limit for the control of future lots of tuberculostatics of equal dosage. As special causes were detected acting in the process, a cause-and-effect diagram was built in order to try to discover, in each factor that composes the productive process, the possible causes of variation of the capsules average weight. The hypotheses raised will be able to serve as a base for deepened the study to eliminate or reduce these interferences in the process. Also a study on the capacity of the process to attend the specifications was carried out, and this study has shown the process´s inaptitude to take care of them. However, on the side of NUPLAM exists a real yearning to implant the SPC and consequently to improve the existing quality already present on its medicines

Ergonomia, sustentabilidade sócio-ambiental e atividade de pesca artesanal com jangadas: estudo de caso na Praia de Ponta Negra, Natal-RN

The fishing is made possible by the handiwork of a fisherman, not using appliances that achieve the same levels of industrial fishing productivity and not causing environmental impacts on fish stocks with the same intensity. The adoption of sustainability practices in this type of fishing has been requested for the achievement of environmental and socioeconomic improvements, since its production has been decreasing over the years and overfishing has led to reduced stocks also stand out environmental aggressions such as pollution. Thus, this research aims to analyze the interference of environmental aspects/impacts that permeate the activity performed by fisherman on the beach of Ponta Negra, Natal-RN, in order to propose recommendations for environmental sustainability. We used a methodology based on the ergonomic work analysis (WISNER, 1987; GUERIN, 2001; VIDAL, 2008) using techniques such as observational and interactional observation protocols, photographs, videos, conversational action, and listening to verbalizations. To understand the vulnerability of the environment in which the activity is carried fisherman and the interferences that it suffers, we used the study of environmental aspects/impacts (SÁNCHEZ 2008). As a result, it appears that from the observations located and reports raftsmen, changes in the sea, the search for new fishing grounds farther from the coast, reducing fishery production, waste generation and pollution of the workplace, and the difficulty in docking rafts, factors arising from the pressures both for society as Seen by fisherman, denoting the necessity of drawing up recommendations and actions proposed by management activity by promoting discussion among raftsmen and accountable institutions, and training through workshops on environmental education, aiming to positive changes in the activity fisherman from Ponta Negra and the environment in which raftsmen are inserted in order to seek a sustainable activity, preserving its characteristics

Avaliação da temperatura de cristalização da parafina em sistemas: parafina, solvente e tensoativo

The formation of paraffin deposits is common in the petroleum industry during production, transport and treatment stages. It happens due to modifications in the thermodynamic variables that alter the solubility of alkanes fractions present in petroleum. The deposition of paraffin can provoke significant and growing petroleum losses, arriving to block the flow, hindering to the production. This process is associated with the phases equilibrium L-S and the stages and nucleation, growth and agglomeration the crystals. That process is function of petroleum intrinsic characteristics and temperature and pressure variations, during production. Several preventive and corrective methods are used to control the paraffin crystallization, such as: use of chemical inhibitors, hot solvents injection, use of termochemistry reactions, and mechanical removal. But for offshore exploration this expensive problem needs more investigation. Many studies have been carried through Wax Appearance Temperature (WAT) of paraffin; therefore the formed crystals are responsible for the modification of the reologics properties of the oil, causing a lot off operational problems. From the determination of the WAT of a system it is possible to affirm if oil presents or not trend to the formation of organic deposits, making possible to foresee and to prevent problems of wax crystallization. The solvent n-paraffin has been widely used as fluid of perforation, raising the production costs when it is used in the removal paraffin deposits, needing an operational substitute. This study aims to determine the WAT of paraffin and the interference off additives in its reduction, being developed system paraffin/solvent/surfactant that propitiates the wax solubilization. Crystallization temperatures in varied paraffin concentrations and different solvents were established in the first stage of the experiments. In the second stage, using the methodology of variation of the photoelectric signal had been determined the temperature of crystallization of the systems and evaluated the interferences of additives to reduction of the WAT. The experimental results are expressed in function of the variations of the photoelectric signals during controlled cooling, innovating and validating this new methodology to determine WAT, relatively simple with relation the other applied that involve specific equipments and of high cost. Through the curves you differentiate of the results had been also identified to the critical stages of growth and agglomeration of the crystals that represent to the saturation of the system, indicating difficulties of flow due to the increase of the density

Análise da genotoxicidade das águas da Lagoa da Extremoz - RN

The contamination of the waters resources for wastewater from industrial, agricultural, and domestic sources is a serious environment problem, compromising its use for human consumption and agriculture. The Extremoz-RN Lake is an important freshwater source for the supply of the city of Natal, supplying a population of approximately 160,000 habitants. This aquatic body is located near an industrial pole which can be a serious risk factor for quality of its waters. The objectives of this study were examined the genotoxicity of Extremoz Lake between September of 2006 and January of 2008, by a combination of the Allium micronucleus test, piscine micronucleus test and the comet assay in erythrocytes from peripheral blood of Oreochromis niloticus. Additionally, the level of eight different heavy metals was quantified through spectrometry of atomic absorption of flame. The Allium test did not detect increase in the frequencies of micronucleus in none of the analyzed periods, however a strong cytotoxic activity was demonstrated for decrease in mitotic index in the analyses carried in April and July of 2007. Negative results had been detected in the frequencies of micronucleus in O. niloticus. A statistic significant increase was observed in the levels of DNA damage in comet assay carried in July of 2007. The results of the chemical analysis had detected increase in the levels of cadmium, chromium, copper, nickel, lead and zinc in different periods. These results demonstrated an alteration of the water s quality of the Extremoz Lake caused for the contamination for heavy metals and increase of DNA strand breaks. The use of biomonitoring program of the heavy metal and other pollutants with genotoxic potential combinated with genotoxicity assays is recommends.

No tempo dos brotos: juventude e diversão em Petrópolis e no Tirol (1945-1960)

The urban growth of Rio Grande do Norte capital gave his boldest step in the three earlier decades of the twentieth century seeking to catch up with foreign metropolis and also most developed Brazilian cities, for example, Rio de Janeiro. Novelties were such bulky that we can notice the rise of a new city which in many aspects superseded that one considered provincial by local intelligentsia. These urban interferences scratched city ground leaving indelible marks until the present day. The exacerbated growth of the city related to the 1940s, when Natal begins hosting the largest allied military base outside United States in the advent of World War II is important at a time when the city´s population doubled. The emergence of new leisure institutions, amidst already existing ones, continued marking the places as sociabilities and leisure permeated with meanings and representations are revealed. This work sought to know the sociability of Tirol and Petrópolis neighborhoods in Natal, in the period from 1945 to 1960, when the city witnesses the consolidation of a market increasingly focused on leisure and young people start to have a special participation in this process.
