José Lins do Rego e a modernização da economia açucareira

Analysis of the northeastern sugar economy insertion on the modernization process of these economy based on the José Lins do Rego literary Discourse. In order to do so, there were used the literary works Fogo Morto, Menino de Engenho, Bangüê and Usina as study objects. Throughout the prosecution of a exploratory and documental bibliographic research it was identified that, in the cited literary works, there are three specialties corresponding to the main scenarios of the plots, the Santa Fé and Santa Rosa mills and the Bom Jesus mill factory. We have conceived the mills as main charachters, since all stories deployment corresponds to the other charachters reactions to the many forms that the specialties are, or not, affected by the modernization. Therefore, the narratives in Fogo Morto, Menino de Engenho, Bangüê and Usina reaffirm the viability of the literary discourse application as a source for the construction of the sociological interpretation of the northeastern sugar economy process of modernization in the end of 19th century and beginning of the 20th century

Contando o passado, tecendo a saudade: a construção simbólica do engenho açucareiro em Jose Lins do Rego (1919-1943)

In this work I have searched the symbolical sense of a specific place. I have started from the theoretical assumption that places are social relations resulting from material and symbolical conditions developed in a certain time and by certain factors. In this sense, I have analyzed the symbolical aspect of sugar plantation from some literary works created by the writer José Lins do Rego from the state of Paraíba. I intend to analyze the symbolical dimension senses, values and images used by this writer to show the sugar plantation. Giving special attention to the works from the named cycle of sugar plantation , I have searched for the senses and meanings used in José Lins do Rego literary discourse to create a fictional sugar plantation, showing this place in a specific way. Based in cultural history, I have used several sources: literary works, prefaces of books, memory works, journalistic works, letters written by intellectual men and history books. My time of analysis is from 1919 the beginning of José Lins do Rego s intellectual activity - until 1943 publication of Fogo Morto, last literary work that I have analyzed. In symbolical terms, what is sugar plantation, this place that has totally touched José Lins do Regos life and literary work? That was the structural question that has determined the present research

Efeito da adição dos azocorantes DR73 e DB79 nas propriedades do poli(metacrilato de metila)

Currently new polymeric materials have been developed to replace other of traditionally materials classes. The use of dyes allows to expand and to diversify the applications in the polymeric materials development. In this work the behavior and ability of azo dyes Disperse Blue 79 (DB79) and Disperse Red 73 (DR73) on poly(methyl methacrylate) (PMMA) were studied. Two types of mixtures were used in the production of masterbatches: 1) rheometer 2) solution. Processing by extrusion-blow molding of PMMA was carried out in order to evaluate the applications of polymeric films. Thermal analysis were performed by thermogravimetry to evaluate polymer and azo dyes thermal stability. Colorimetric analysis were obtained through monitoring the spectral variations associated with sys/trans/anti azo dyes isomerization process Colorimetric data were treated and evaluated in accordance to the color system RGB and CIEL*ab, by monitoring the color change as function of time. Mechanical properties, characterized by tensile tests, were evaluated and correlated with the presence and content of azo dyes in the samples. Analyses by scanning electronic microscopy (SEM) were performed on the surfaces of samples to check the azo dye dispersion after the mixing process. It was concluded that the production of PMMA/azo dyes is possible and feasible, and the mixtures produced had synergy of properties for use in various applications

A dupla poética do silêncio: uma análise de Fogo morto e Cartilha do silêncio.

This research presents a reading of the poetics of silence in the profile and actions of characters in Fogo morto, by Paraiba s novelist José Lins do Rego and Cartilha do silêncio, by Sergipe s writer José Francisco Costa Dantas. As a starting point, we intend to demonstrate, through analysis, how the traditional issue of patriarchy, installed in rural areas of Northeast Brazil, live their momentum of rise and decline in different social spaces within narratives. This article shows how man lives tensions caused by the socio-political changes that will gradually be deployed in their environment due to the process of transition from traditional to modern life. From this perspective, this reading encourages a critical reflection on the social space of the mills and farms at the time of their rise and decay, as well as the various gender relationships between the feminine and the masculine world. The analysis indicates that all the changes both in family and social space unfold a world of silent variants and this paper takes as its theoretical basis the concept of silence built from the reflections of Eni Puccinelli Orlandi (2002), Barros Lourival Holland (1990 ), Luiz Costa Lima (1974) and Marisa Simons (1999).

A esfera como metáfora: representações do futebol no campo da literatura (leituras do tema no conto de ficção)

Football, understood as a phenomenon of sports practice and nearly universal coverage, can also be seen as a game whose operation circumvents the cultural universe of people who practice it. Much more than just a sport, so this game is a cultural phenomenon par excellence, bearing a communicational and aesthetic dimension whose occurrence has been spotted in various fields of scientific and cultural. Therefore, it is as game and as a phenomenon of culture, we intend to focus on football here as an object of study. Our aim is to investigate the sport in Brazil taking the Literature and Journalism as privileged instances of their representation in the media. Thus, the central idea of this research is to show when and how football has become a recurrent theme in Brazilian literature, starting with its journalistic approach until we get an overview of the aesthetic representation of the game, Literature as the main focus of attention and taking the genre of fiction story as material fact of their representation. With this approach, we intend to develop an overall view, overview of the literature about football in our country and at the same time, particularize this vision in some representative authors of it, like the writer-journalist Mario Filho (the historian, essayist on the modernization of chronic specific theme), José Lins do Rego (writer passionate about the game), Nelson Rodrigues (the esthetician that elevated the sport to the status of art by chronic), Lima Barreto (who along with Antonio de Alcantara Machado pioneered the formalized within the fiction) and the storytellers of the topic itself. In the end, we intend to infer the results of evaluations and reviews of books and authors listed, we have examined a wide sense, but also vertical (and which were focused on a socio-historical perspective and critical-aesthetic) within the assumption that seems be a homology between the way football practice amongst us will historically winning characteristics as to form a Brazilian school of football, and how our writers, journalists will be addressing the topic, which also would focus on creating a "Brazilian way" of telling literary football. The proof of this hypothesis operational work together with the development of historiography and the necessity arising from it, creating a "Guide to Reading football theme in fictional tale of Brazil" shut the focal perspective of this study

Os Brutos: tradição literária e a memória cultural do Seridó

Partindo do princípio de que a força centralizadora do discurso do narrador sob o universo romanesco encontra-se regido por nuanças sócio-ideológicas que fazem parte do mundo psicológico do autor, procede-se uma leitura crítica de Os Brutos (1938), romance de estréia do escritor José Bezerra Gomes. O trabalho mencionado visa a tecer algumas considerações em torno do ponto de vista do narrador, enfocando a encenação do EU no cenário artístico-literário e sua interferência no modo de narração da citada obra. O procedimento metodológico adotado foi a pesquisa bibliográfica, e como aporte teórico recorreu-se à crítica especializada que trata da temática em questão. Ao final percebeu-se que o discurso do narrador possui um caráter ambivalente, o qual permite que o interlocutor presente não assuma uma perspectiva fixa diante do que narra

Das relações entre imaginário e poesia na obra de Orides Fontela: o regime diurno da imagem

The present work seeks essentially to demonstrate how some anthropological structures of the imaginary, theorized by the French thinker Gilbert DURAND, projected themselves in a noticeable manner in the poetic work of the Brazilian poet Orides FONTELA. Chiefly we will demonstrate with great care in what way this projection and vivification occur through an imagination that not only materializes some fundamental archetypes of the human imagination, but also seeks to organize them through original poems in its form of presenting the poetic discourse, giving here a different contribution of the mythical or religious discourse, privileged places, since always, where the symbolic functions also manifest themselves

Modelagem da transferência de massa na remoção do óleo da água produzida por flotação em coluna com uso de tensoativos de origem vegetal

The treatment of oil produced water and its implications are continually under investigation and several questions are related to this subject. In the Northeast Region Brazil, the onshore reservoirs are, in its majority, mature oil fields with high production of water. As this oil produced water has high levels of oil, it cannot be directly discarded into the environment because it represents a risk for contamination of soil, water, and groundwater, or even may cause harm to living bodies. Currently, polyelectrolytes that promote the coalescence of the oil droplets are used to remove the dispersed oil phase, enhancing the effectiveness of the flotation process. The non-biodegradability and high cost of polyelectrolytes are limiting factors for its application. On this context, it is necessary to develop studies for the search of more environmentally friendly products to apply in the flotation process. In this work it is proposed the modeling of the flotation process, in a glass column, using surfactants derived from vegetal oils to replace the polyelectrolytes, as well as to obtain a model that represents the experimental data. In addition, it was made a comparative study between the models described in the literature and the one developed in this research. The obtained results showed that the developed model presented high correlation coefficients when fitting the experimental data (R2 > 0.98), thus proving its efficiency in modeling the experimental data.

Ensaios de tratabilidade aplicados a determinação de parâmetros para dimensionamento de processos de tratamento de água de manancial eutrofizado

Eutrophication is a growing process present in the water sources located in the northeast of Brazil. Among the main consequences of these changes in trophic levels of a water source, stands out adding complexity to the treatment to achieve water standards. By these considerations, this study aimed to define, on a laboratory scale, products and operational conditions to be applied in the processing steps using raw water from Gargalheiras dam, RN, Brazil. The dam mentioned shows a high number of cyanobacteria, with a concentration of cells / ml higher than that established by Decree No. 518/04 MS. The same source was also considered by the state environmental agency in 2009 as hypereutrophic. The static tests developed in this research simulated direct filtration (laboratory filters) and pre-oxidation with chlorine and powdered activated carbon adsorption. The research included the evaluation of the coagulants aluminum hydrochloride (HCA) and alum (SA). The development of the research investigated the conditions for rapid mixing, the dosages of coagulants and pHs of coagulation by the drawing of diagrams. The interference of filtration rate and particle size of filtering means were evaluated as samples and the time of contact were tested with chlorine and activated carbon. By the results of the characterization of the raw water source it was possible to identify the presence of a high pH (7.34). The true color was significant (29 uH) in relation to the apparent color and turbidity (66 uH and 13.60 NTU), reflecting in the measurement of organic matter: MON (8.41 mg.L-1) and Abs254 (0.065 cm-1). The optimization of quick mix set time of 17", the speed gradient of 700 s-1 in the coagulation with HCA and the time of 20" with speed gradient of 800 s-1 for SA. The smaller particle sizes of sand filtering means helped the treatment and the variation in filtration rate did not affect significantly the efficiency of the process. The evaluation of the processing steps found adjustment in standard color and turbidity of the Decree nº 518/04 MS, taking in consideration the average values found in raw water. In the treatment using the HCA for direct filtration the palatable pattern based on the apparent color can be achieved with a dose of 25 mg L-1. With the addition of pre-oxidation step, the standard result was achieved with a reduced dose for 12 mgHCA.L-1. The turbidity standard for water was obtained by direct filtration when the dose exceeds 25 mg L-1 of HCA. With pre-oxidation step there is the possibility of reducing the dose to 20 mg L-1.The addition of CAP adsorption, promoted drinking water for both parameters, with even lower dosage, 13 mg L-1 of HCA. With coagulation using SA removal required for the parameter of apparent color it was achieved with pre-oxidation and 22 mgSA.L-1. Despite the satisfactory results of treatment with the alum, it was not possible to provide water with turbidity less than 1.00 NTU even with the use of all stages of treatment

Show de Mamulengos Heraldo Lins: construções e transformações de um espetáculo na cultura popular

The theater of puppets is one of the many expressions of popular culture which is marked by ongoing constructions and transformations in its symbolic representations as well as its characters and performances. In the city of Natal/RN, there is a manipulator called Heraldo Lins, an artist who operates such puppets, and has been performing his puppet since 1992. Lins has his own look at how he produces his performances and seeks to adjust his puppets to social and rentable contexts. Lins‟s performances are tailor-made in accordance with the request of his customers, as he makes up the passages and lines of his puppets according to his audience. This research aimed to study how the Heraldo Lins Mamulengos Show is built, especially its changes. We note that Lins chooses to dismantle the symbolic values of the tradition in the regular puppet theater once he adapts to modern patterns, placing himself between the traditional puppet theater and the cultural industry. The work in camp was made through a methodological focused in a participative observation and an audiovisual registry

Comunidade fitoplanctônica e qualidade da água da lagoa do jiqui, parnamirim, rn

It is important to evaluate the quality of water for proper management of these resources, since the increase of environmental degradation and the multiple use of water resources are decreasing the quality of water consumed by living beings. The objective of this study was to characterize the phytoplankton community and its variations during periods of dray and rain in Jiqui Lake located in Parnamirim, RN. It was also aimed to analyze the physical and chemical factors of this environment, in order to contribute to the knowledge of water quality used for human consumption. The collection of water samples were carried out in September 2008 to August 2009. The collection of the phytoplankton community was carried out in four sampling sites (surface, bottom, margin of the lake without macrophytes and site dominated by macrophytes). Phytoplankton was collected using plankton net of 20m. The analysis of nutrients and identification of phytoplankton were performed in the laboratory. The results indicate that concentration of chlorophyll a was high in the bottom with mean value of 1.07 μgL-1 (SD ± 1.61). During the study period there was a dominance of the following species: Euglena gracilis, Trachelomonas sp, Cyclotellas sp, Gomphonema apuncto, Navicula cuspidata var. cuspidata, Navicula sp, Rhopalodia gibba. There was homogeneity between limnological values in the four study sites, with significant difference between the periods of drought and rain. The Jiqui Lake is considered oligotrophic due to its low concentrations of chlorophyll a, high transparency and low levels of nutrients. The values of BOD and chlorophyll a concentration remained below the permitted standards existing for freshwaters in Brazil, thus the water from Lake Jiqui is of good quality, suitable for human consumption.

Comunidades zooplanctônicas como bioindicadoras da qualidade da água de quatro reservatórios da região semi-árida do Rio Grande do Norte

The response of zooplankton assemblages to variations in the water quality of four man-made lakes, caused by eutrophication and siltation, was investigated by means of canonical correspondence analysis. Monte Carlo simulations using the CCA eingenvalues as test statistics revealed that changes in zooplankton species composition along the environmental gradients of trophic state and abiogenic turbidity were highly significant. The species Brachionus calyciflorus, Thermocyclops sp. and Argyrodiaptomus sp. were good indicators of eutrophic conditions while the species Brachionus dolabratus, Keratella tropica and Hexarthra sp. were good indicators of high turbidity due to suspended sediments. The rotifer genus Brachionus was the most species-rich taxon, comprising five species which were associated with different environmental conditions. Therefore, we tested whether this genus alone could potentially be a better biological indicator of these environmental gradients than the entire zooplankton assemblages or any other random set of five species. The ordination results show that the five Brachionus species alone did not explain better the observed pattern of environmental variation than most random sets of five species. Therefore, this genus could not be selected as a target taxon for more intensive environmental monitoring as has been previously suggested by Attayde and Bozelli (1998). Overall, our results show that changes in the water quality of man-made lakes in a tropical semi-arid region have significant effects on the structure of zooplankton assemblages that can potentially affect the functioning of these ecosystems

Otimização de vazão de poços injetores em projeto de injeção de água utilizando simulação por linhas de fluxo

Until the early 90s, the simulation of fluid flow in oil reservoir basically used the numerical technique of finite differences. Since then, there was a big development in simulation technology based on streamlines, so that nowadays it is being used in several cases and it can represent the physical mechanisms that influence the fluid flow, such as compressibility, capillarity and gravitational segregation. Streamline-based flow simulation is a tool that can help enough in waterflood project management, because it provides important information not available through traditional simulation of finite differences and shows, in a direct way, the influence between injector well and producer well. This work presents the application of a methodology published in literature for optimizing water injection projects in modeling of a Brazilian Potiguar Basin reservoir that has a large number of wells. This methodology considers changes of injection well rates over time, based on information available through streamline simulation. This methodology reduces injection rates in wells of lower efficiency and increases injection rates in more efficient wells. In the proposed model, the methodology was effective. The optimized alternatives presented higher oil recovery associated with a lower water injection volume. This shows better efficiency and, consequently, reduction in costs. Considering the wide use of the water injection in oil fields, the positive outcome of the modeling is important, because it shows a case study of increasing of oil recovery achieved simply through better distribution of water injection rates
