Ribeira, técnica versus natureza: transformações em prol de um projeto de modernização (1860-1932)

The necessity of the insertion of the capital of Rio Grande do Norte in the world-wide commercial scene and its claim as the seat of political power, in ends of nineteenth and beginning of twentieth century, determined the direction of urban interventions undertaken by government to restructure the city. In that matter, there were several actions of improvements and embellishment in Natal, which had, as a starting point, the adequacy works of the port, located in the Ribeira quarter, with the aim of ending the physical isolation that reinforced its economic stagnation. Besides the problems faced in the opening bar of the Potengi River, and would complement the required improvements, other barriers demonstrate the tension established between the physic-geographic field and the man: the flooded and slope which connected Cidade Alta and Ribeira the first two quarters of the city.The execution of these works demanded knowledge whose domain and application it was for engineering. But, how the actions done for the engineers, in sense to transform natural areas into constructed spaces made possible the intentional conformation of the quarter of the Ribeira in a commercial and politician-administrative center, in the middle of the XIX century and beginning of the XX? Understand, therefore, the employment effects of technology on the physical-geographical Ribeira, is the objective of this work that uses theoretical and methodological procedures of Urban Environmental History, by analyzing the relationship between the environment and the man, mediated by knowledge and use of technologies. The documental research was used, as primary sources, the Messages of the Provincial Assembly Government that later became the Legislative Assembly of Rio Grande do Norte reports and articles on specialized publications, in addition to local newspapers. The work is structured in five chapters. First, some comments about Urban Environmental History (Chapter 1) supplemented with analysis of the conceptual construction of nature in the Contemporary Era and its application in the city (chapter 02), the following chapters (03 and 04) deal with the rise of engineers as a active group in the Brazilian government frameworks and their vision about the nature inside the urban environment and it is studied how the professional technicians dealt with the improvement work of the harbor and in the shock with the natural forces. Other works that would complement this "project" of modernization and had had natural obstacles to be removed the Ribeira flood and slope constitute the subject of the fifth chapter. Finally, some final considerations retake the initial discussions aiming an association between the technique and the nature as junction elements inside the process of constitution of a Modern Natal

Humor gráfico: o sorriso pensante e a formação do leitor

This research investigates the graphic humor, in particular the political cartoon and the cartoon, texts characterized by mixing visual-oral language, and its contribution in the formation of the reader. Recovers the main theories about the comicality in general and verifies the presence of these concepts into the texts of graphic humor and how they articulate themselves within the process of seducing the reader. Grounded in the studies of Umberto Eco about the cultural industry products and its relations with the literary theories and the aesthetics reception. After analysing texts of graphic humor, the study concludes that the triad, image-word-humor reveal a sophisticated arrangement which allows the reader to practice effectively the political cartoons and cartoons of production, of sense, cooperating in such a singular manner to the formation of a reflexive reader

Estudo da flamabilidade e resistência à chama de compósito de poliéster insaturado e fibra da folha do abacaxizeiro (PALF)

In the present research work, composites were prepared using pine apple leaf fibres (PALF) as reinforcement with unsaturated polyester resin as matrix, incorporating with fire retardant at different compositions. The PALF was obtained from the decortication of pine apple leaves obtained from Ramada 4 from Ielmo Marinho in the State of Rio Grande do Norte. The unsaturated polyester resin and the catalyzer were bought from the local establishment. The fire retardant, aluminium tri-hydroxide - Al(OH)3 was donated by Alcoa Alumínio S.A and was used in the proportions of 20%, 40% and 60% w/w. Initially the fibres were treated with 2% NaOH for 1 hour, to remove any impurities present on the fibre surface, such as wax, fat, pectin and pectate, in order to have a better adsorption of the fibres with the matrix as well as the flame retardant. The fibre mat was prepared in a mat preparator by immersion, developed in the Textile Engineering Laboratory, at the UFRN. The composites (300x300x3 mm) were prepared by compression molding and the samples (150x25x3 mm) for analysis of the properties were cut randomly using a laser cutter. Some of the cut samples were used to measure the smoke emission and fire resistance using UL94 standard. Mechanical tension-extension and flexural properties were carried in CTGás RN and the Laboratório de Metais e Ensaios Mecânicos Engenharia de Materiais UFRN , as well as SEM studies were carried out at Núcleo de Estudos em Petróleo e Gás Natural - UFRN . From the observed results, it was noted that, there was no marked influence of the fire retardant on the mechanical properties. Also in the water absorption test, the quantity of water absorbed was less in the sample with higher concentration of fire retardant. It was also observed that the increase in the proportion of the fire retardant increased the time of burning, may be due to the compactness of the composite due to the presence of fire retardant as a filling material even though it was meant to reduce the rate of inflammability of the composite

Fabricação de eco-composito com a fibra de lã canina

The Sustainability has been evidence in the world today; organizations have sought to be more and more into this philosophy in their processes, whether products or attendance. In the present work were manufactured eco-composites with animal fiber (dog wool) that is currently discarded into the environment without any use. The fibers were characterized and made matting (non-woven). The phases of the project were consisted to develop methods and to convert these fibers (booster) blended with polyester resin (matrix) in different proportions (10%, 20% and 30%) at the composite. Were studied fiber characteristics, mechanical properties of the composites, water absorption and scanning electron microscopy. Initially, the fibers were treated with solution of sodium hydroxide of 0.05 mols, and then taken to matting preparing at the textile engineering laboratory - UFRN. The composites were made by compression molding, using an orthophthalic polyester resin as matrix and 1% MEK (methyl ethyl ketone peroxide) as initiator (catalyst). To evaluate the mechanical tests (tensile and flexural) and water absorption were made twelve specimens with dimensions 150x25x3 mm were cut randomly. According to the standard method, tensile tests (ASTM 3039) bending tests (ASTM D790) were performed at the mechanical testing of metals at laboratory UFRN. The results of these tests showed that the composite reinforced with 30% had a better behavior when exposed to tension charge; while on the three points bending test showed that the composite reinforced with 10% had a better behavior. In the water absorption test it was possible to see that the highest absorption happened on the composite reinforced with 30%. In the micrographs, it was possible to see the regions of rupture and behavior of the composite (booster / matrix)

Utilização de chama para controle de plantas daninhas emersas em ambiente aquático

Dois estudos foram conduzidos com o objetivo de avaliar os efeitos da aplicação de chama no controle de Eichhornia crassipes, Brachiaria subquadripara, Pistia stratiotes e Salvinia auriculata. No primeiro estudo foram utilizadas diferentes doses de chama, representadas pela quantidade de gás consumida durante a aplicação, e, no segundo, usaramse duas aplicações de chama em intervalo de 14 dias, uma aplicação seqüencial (intervalo de sete dias) e aplicação única. As diferentes doses, tanto no primeiro quanto no segundo, foram comparadas com plantas que não receberam nenhum tratamento térmico. Avaliações de injúria foram realizadas aos 1, 3, 7, 10, 14, 17, 21 e 30 após a aplicação dos tratamentos, sendo realizadas também avaliações das biomassas secas das plantas aquáticas remanescentes em cada tratamento, ao final dos ensaios. No primeiro estudo foram observadas reduções significativas na produção da biomassa seca das espécies E. crassipes, B. subquadripara e P. stratiotes tratadas com as maiores doses referentes aos consumos de gás. Doses menores não diferiram estatisticamente da testemunha quanto à produção de biomassa seca, exceção feita para a espécie P. stratiotes. Todas as aplicações seqüenciais proporcionaram redução acima de 90% na produção da biomassa seca de E. crassipes e B. subquadripara. As aplicações seqüenciais e únicas proporcionaram reduções abaixo de 37% na produção da biomassa seca de S. auriculata. Os resultados demonstraram que existe a possibilidade de se utilizar o controle físico através da aplicação de chama como alternativa no manejo de plantas daninhas em ambientes aquáticos.

A paz tensa da chama fugaz: a configuração do amor no romance contemporâneo, Lygia Fagundes Telles e Lídia Jorge

This thesis A paz tensa da chama fugaz: a configuração do amor no romance contemporâneo, Lygia Fagundes Telles e Lídia Jorge aims to study the configuration of Love in contemporary novels. Their corpuses of study are the novels As horas nuas (1989), by the Brazilian writer Lygia Fagundes Telles; and O vento assobiando nas gruas (2002), by the Portuguese writer Lídia Jorge. The following research tries to understand how the characters from those texts deal with some love questions on the context of the contemporary narrative; it also tries to comprehend the love expression which is formed as a contradictorily fluid feeling and intensely wanted, which are important points concerning the love discourse at the present day. As a critic-comparative study, this research focuses on the problematic concerned love as a synonym of Eros, in other words, the relation between lovers, analyzed through social and philosophical perspective. Through that, this work broadens the study of two contemporary novels, and it also establish connections between the characters from those novels and the literary environment where they are placed, once it focuses on the human and social context presented in this books. The thesis ends calling attention to the dichotomy of love and death, to the image of love which grows through absence and through the longing of completeness of the human being; that is why this work sustains that the Lygia Fagundes Telles and Lídia Jorge update and materialized in their texts the plurality of contemporary love conception, which continues to be contradictory, fragmented and problematic

Maus ares e malária: entre os pântanos de Natal e o feroz mosquito africano (1892-1932)

The development of epidemiological practices in the last years of the nineteenth and early twentieth century was characterized by both an influence of medical geography and the emergence of microbes and vectors of diseases. Both theories were used to explain outbreaks in Rio Grande do Norte specially in Natal. In this process were organized new institutions linked to public health, unhealthy spaces and prescribed hygiene measures. The redefinitions of the spaces were linked to updated elements of Hippocratic medicine such as aerism and emphasis on medical topography. How the physicians of the town were organized in the face of new meanings and fields of expertise in the demarcation of diseases and regulation of their own practices against the illegal medical practitioners? Likewise, the very occurrence of epidemics mobilized people, urban institutions and apparatuses. But how the Hippocratic legacy that leads to the idea of bad air originated by swamps from the eighteenth and nineteenth century has been linked to new microbial assumptions and disease vectors in the early twentieth century? How an invader from Africa, (the mosquito A. gambiae) mobilized transnational efforts to combat malaria and redefined the epidemiological practices? The aim of this work is to understand how epidemiological practices redefine the way we define spaces, practices and disease from both an approach influenced by a relational history of spaces and a theoretical synergy which includes topics in Science Studies, Post Structuralist Geography and some elements of Feminist Studies. Documentary research were surveyed in the reports of the provincial presidents, government posts to the Provincial Assembly, specialized medical articles and theses, and documents from the Rockefeller Foundation and national and international journals. In this regard shall be given to both material and discursive aspects of space-related practical epidemiological that Natal as much (in general) Rio Grande do Norte between bad air and malaria.

Quem nasce em campina grande é campinense : futebol e sociabilidade na rainha da borborema (1954-1965)

This study aims to historicize a problem: How Campinense Club, club social of the city of Campina Grande, became a popular club? This guild was founded in 1915 by a group of graduates, which they called "Campinense" a social club dedicated to the enjoyment of the city's elites. To investigate the mechanisms that have led to this popularity, was chosen that includes a period from 1954 to 1965, when it was created a department where the professional football club won a string of six consecutive championships, considered the main achievement of its history sports. Were used as research sources Borborema the Journal, a newspaper founded in 1957 and that during the period in question, was the spokesman of the main political groups in the city, which on many occasions were the sponsors of the clubs the same. This newspaper had a daily sports column and introduced the red-black team to Paraíba. Were used, although the club's meeting minutes taken as official documents, which allowed it to be mounted on a puzzle of the club's events, since the information about the Campinense present rather fragmented. Finally, respondents were fans, athletes and leaders who, through his lines in a way pointed out other possibilities such as a club, believed to be aristocratic, has become a passion among the fans, giving rise to this conception to be one that Campinense broke with the established elites of the city.

TELA EXCLUIDORA DE RAINHA NA PRODUÇÃO DE MEL E NA LONGEVIDADE DAS OPERÁRIAS em COLMEIAS DE Apis mellifera

Este trabalho tem como objetivos verificar as áreas de cria e alimento e a longevidade de operárias em colmeias de Apis mellifera, em apicultura fixa (mata) e migratória (laranja e eucalipto), sem (T1) e com (T2) tela excluidora de rainha. Foram utilizadas colmeias modelo Langstroth, com sobrecaixa. Na apicultura fixa, estas colmeias foram analisadas durante 476 dias e mapeadas a cada 30 a 45 dias para obtenção das áreas de cria e alimento. Na migratória, as colmeias foram analisadas antes e após a florada. Foi estudada também a longevidade das operárias, nos dois tratamentos. Os dados mostraram que em fluxo baixo de néctar (apicultura fixa, em mata), o uso de tela excluidora apresentou maior eficiência na separação do mel das crias. Entretanto, quando o fluxo de néctar foi alto (floradas de laranja e eucalipto), a tela excluidora não foi eficiente, pois as abelhas rapidamente preencheram os favos disponíveis no ninho inferior, misturando-o com cria. Observou-se também redução na longevidade das operárias das colmeias com tela excluidora, em dois dos três testes realizados. Este trabalho, desenvolvido em três locais diferentes, com plantas apícolas distintas evidenciou também a variabilidade e a grande influência ambiental no desenvolvimento das colônias de Apis mellifera.
