Combater as secas e defender as florestas a natureza nos desafios da ciência e da técnica para modernizar o Brasil (1889 a 1934)

In the first decades of 20th century the just instituted Brazilian Republic faced the challenge to modernize the country. Considering that the progress was associated with the exhaustion of the forest reserves and with climatic changes, two big issues were seen as fundamental: To Fight the Droughts and To Defend the Forests; headed by professionals who were dedicated to these ideals. This research starts from the premise that these were the main challenges enforced by nature to the Brazilian development; the general objective was delimited in the search to understand the meaning and the conception of the natural world by this group of professionals who faced the shock between modernizing the country and conserving its natural resources. Aiming to contribute with the construction of the Brazilian environmental history and to bring historical elements to the debate about the environment in the country, the author concentrates his attention to the analyses, the discussions and the actions that preceded the regulation on the use of natural resources and the implementation of the environmental legislation in Brazil, occurred in 1934. The investigation uses as methodological basis the theoretical directions of environmental history, using sources of data still little explored and valued. In such way, it is taken as starting point some published papers about this subject during the period between 1889 and 1934 in two technical magazines the Revista Brazil Ferro-Carril and the Revista do Club de Engenharia. National engineering played a basic role in this process while arguing, projecting and constructing the development. The formulated proposals, after being divulged, had fomented the interchange with other professionals and had favored the advance of ambient questions in Brazil, in the sense to preserve natural resources, to construct more harmonic relations between the society and the nature and to equate the development with the environment preservation

Habitus docente e representação social do ensinar Geografia na Educação Básica de Teresina - Piauí

The literature about the Geography teaching has shown that most male and female teachers of this subject go on guiding their teaching practice based on the traditional Geography fundamentals, whose main characteristic consist in the description of places. The incorporation of scientific standards that change the old principles and concepts have not been happening, unless in a punctual way. The overcoming of the traditional Geography, related to the aspects accepted by the scientific field have not happened in Brazil yet, not only because of certain obvious obstacles, as the literature has been pointed out but also by symbolic obstacles, which block the incorporation of the new, of the non habitual action. One of those obstacles that motivated the accomplishment of this study was the social representations that are theoretically studied here under the perspective developed by Serge Moscovici. Then, the focus of this doctorate study is concentrated in the apprehension of the content and structure of the social representation of teaching of Geography and its relation with the habitus that gives form and social visibility to the ones who are teachers of that subject in Teresina. The consecution of this work was especially based on the Pierre Bourdieu´s praxiology, mainly on the concepts of social field, habitus and capital, as well as the theory of social representations, specifically on the approach of central nucleus developed by Jean-Claude Abric and Jean-Claude Flament. The initial hypothesis pointed out the existence of a Geographer´s primary habitus built through the development process of the geographic science field in Brazil, as a basis of production of a social representation of teaching geography . That representation, however, would act as a symbolic obstacle to the incorporation of the new scientific contents and pedagogical practice, which require from the teacher investigative and questionable attitude in the presence of the reality and contents approached in the classroom. That initial hypothesis laid on the theoretical purpose that it has been developed by Domingos Sobrinho (1997), which states that there is a narrow relationship between the habitus and social representation. The study was developed with male and female teachers of Geography from public schools of Teresina. The methodology involved the use of a questionnaire, the free-word association technique and deep interviews. The achieved results showed the presence of a complex process of representational construction and its articulation with a habitus produced by the synthesis of several situational and cultural referents, from among of them we can point out an insertion in a social field of practice exclusively related to the teaching and the reproduction of a professoral teaching (SILVA, 2003), built through the school development process, which those male and female teachers were exposed. The initial hypothesis that considered the local reproduction of a primary habitus of the Geography was denied, therefore, it was verified that there is not in Teresina the production/reproduction of the structures, rules and practice of the national scientific field, in which this subject is inserted. Hence, the incorporation of the new patterns of the geographic scientific knowledge is difficult because of the inexistence of a scientific habitus, that is, mental schema systems that would let the teachers mentioned above connect themselves appropriately to the science and its practices. So, it has gotten a social representation of teaching geography based on contents strictly related to the reproduction of structures, mental schema from the educational field which attach themselves to the hegemonic pedagogical practices in the national scope

Efeito do uso de óleos vegetais, associados ou não a inseticida, no controle de bemisia tabaci (gennadius, 1889) e thrips tabaci (lindeman, 1888), em feijoeiro, na época das águas

The objective of this experiments was evaluate the control of Bemisia tabaci and Thrips tabaci, through the use of plant oils associated or not to insecticide in bean plants, besides verifying the consequences on yield. The experiment was carried out in the period of rainy seasons, by utilizing Carioca variety. The statistical design was the randomized blocks, by employing a 6x2 factorial scheme ( plant oil versus insecticide), totalizing 12 treatments and four replications. It was concluded thet application of plant oils without insecticide can be utilized on the control of the B. tabaci biotipo B, since their population and the symptoms of golden mosaic was similar to the treatment plant oils plus insecticide; among the plant oils Agrex (R) plant oil promoted a higher control of white fly. For T. tabaci the application of plant oil associated to insecticide provide with a smaller population index when compared to the treatments without this association. The yield was not affected by the population of B. tabaci biotipo B and T. tabaci when plant oils were utilized, associated or not to the insecticide.

Parasitismo natural de ovos do curuquerê-do-algodoeiro por Trichogramma pretiosum em diferentes estágios fenológicos de variedades de algodoeiros em Ipameri, GO

The cotton can be damaged by many pests, standing out among them cotton leafworm, responsible for major losses in production, if not controlled properly. A group of natural enemies is the most studied of the family Trichogrammatidae, mainly species of the genus Trichogramma, because of its importance in biological control at the initial stage of development of their hosts. In order to study the natural egg parasitism of Alabama argillacea (Hubner, 1818) (Lepidoptera: Noctuidae) by Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) in different phenological stages of transgenic and conventional varieties of cotton (Gossypium hirsutum L.) in the region of Ipameri, GO, it was carried out this experiment from december 2007 to april 2008, in the UEG, State of Goias. The experimental design was in randomized blocks with five treatments consisting of the conventional varieties DeltaOPAL, FMX 966, FMX 993, FMX 910 and NuOPAL transgenic variety, in four replications. In the beginning of oviposition of the A. argillacea it was started the 27 old days plant and the parasitism increased as the availability of eggs of the host, regardless of variety. It was found that the varieties over the vegetative cycle did not show statistical differences on the preference for oviposition by the moth neither on the parasitism. The level of parasitism of eggs of A. argillacea by T. pretiosum varied depending on the density of eggs on plants, not in terms of varieties and phenological stages.

Um protocolo de comunicação multicast na camada de aplicação com Consciência de Localização

Internet applications such as media streaming, collaborative computing and massive multiplayer are on the rise,. This leads to the need for multicast communication, but unfortunately group communications support based on IP multicast has not been widely adopted due to a combination of technical and non-technical problems. Therefore, a number of different application-layer multicast schemes have been proposed in recent literature to overcome the drawbacks. In addition, these applications often behave as both providers and clients of services, being called peer-topeer applications, and where participants come and go very dynamically. Thus, servercentric architectures for membership management have well-known problems related to scalability and fault-tolerance, and even peer-to-peer traditional solutions need to have some mechanism that takes into account member's volatility. The idea of location awareness distributes the participants in the overlay network according to their proximity in the underlying network allowing a better performance. Given this context, this thesis proposes an application layer multicast protocol, called LAALM, which takes into account the actual network topology in the assembly process of the overlay network. The membership algorithm uses a new metric, IPXY, to provide location awareness through the processing of local information, and it was implemented using a distributed shared and bi-directional tree. The algorithm also has a sub-optimal heuristic to minimize the cost of membership process. The protocol has been evaluated in two ways. First, through an own simulator developed in this work, where we evaluated the quality of distribution tree by metrics such as outdegree and path length. Second, reallife scenarios were built in the ns-3 network simulator where we evaluated the network protocol performance by metrics such as stress, stretch, time to first packet and reconfiguration group time

Sistema inteligente para detecção de vazamentos em dutos de petróleo usando transformada Wavelet e redes neurais

This work consists in the use of techniques of signals processing and artificial neural networks to identify leaks in pipes with multiphase flow. In the traditional methods of leak detection exists a great difficulty to mount a profile, that is adjusted to the found in real conditions of the oil transport. These difficult conditions go since the unevenly soil that cause columns or vacuum throughout pipelines until the presence of multiphases like water, gas and oil; plus other components as sand, which use to produce discontinuous flow off and diverse variations. To attenuate these difficulties, the transform wavelet was used to map the signal pressure in different resolution plan allowing the extraction of descriptors that identify leaks patterns and with then to provide training for the neural network to learning of how to classify this pattern and report whenever this characterize leaks. During the tests were used transient and regime signals and pipelines with punctures with size variations from ½' to 1' of diameter to simulate leaks and between Upanema and Estreito B, of the UN-RNCE of the Petrobras, where it was possible to detect leaks. The results show that the proposed descriptors considered, based in statistical methods applied in domain transform, are sufficient to identify leaks patterns and make it possible to train the neural classifier to indicate the occurrence of pipeline leaks

O ensino de língua inglesa em um instituto federal : uma análise das recomendações documentais e da perspetiva dos professores

This work aims to understand the teaching of English at the Federal Institute of considering the recommendations of official and technical documents for the integrated secondary school and the perspective of the English teachers settled in one of the campuses of the Institute. It is also an objective of this research to infer as to what extent the perspective of teachers is articulated to the documental recommendations. For this purpose, several official and technical documents (LÜDKE; ANDRÉ, 1986), such as the PCNEMs (BRAZIL, 2000), the OCNEMs (BRAZIL, 2006) and the Political-Pedagogical Project of the Institute (IFRN, in press) were gathered, and a questionnaire was submitted to six teachers of English from one of the campuses of the institution. The theoretical references of the research include, among others, Bakhtin (1997; 1999), Widdowson (1991), Almeida Filho (2011; 2004), Celani (1988; 2009), Hutchinson and Waters (1987) and Dudley-Evans and St. John (1998). The results show that the teaching of English according to the documents predicts the instrumental use of the foreign language, but suggests the development of competences and skills as contextualized social practices, aimed at the education of the student as a professional-citizen. The perspective of teachers, in turn, points to a concern that the teaching of English serves as a tool for improving student life through the instrumental use of language as a means of accessing information and professional training. This finding reveals that the articulation between the documental recommendations and perspective of teachers does not go beyond what refers to the instrumental language teaching, since teachers do not show, when reporting their practices, the teaching of language as social practice, as mentioned in the legal texts

O teatro de Deus: a construção do espaço sagrado de juazeiro a partir de narrativas femininas (Ceará, 1889-1898)

In this work, we discuss the construction of Juazeiro in the state of Ceará -, as a sacred space from the analysis of the testimonies of nine religious women called beatas in an Episcopal process in the late nineteenth century. This process was initiated in 1891 to investigate the occurrence of an Eucharistic miracle with beata Maria Magdalena do Espírito Santo de Araújo. We show that the punitive strategies of the Diocese eventually caused a reordering of pilgrimages to Juazeiro which until 1894 worshipped the Precious Blood and that after the condemnation of the phenomena by the Holy See are rearranged around the figure of Father Cicero Romão Batista, under the pretext of worshipping the priest himself and also Nossa Senhora das Dores, currently the patron saint of the city of Juazeiro do Norte.

Em nome da cidade vencida: a São Luís republicana em José do Nascimento Moraes (1889 1920)

Cette dissertation a pour but d´analyser la ville de São Luís do Maranhão pendant la Première Republique, d´après le roman Vencidos e Degenerados, de José do Nascimento Moraes, publié en 1915. À partir des rapports entre l´Histoire et la Littérature, nous nous intéressons à la façon dont l´auteur écrit l´histoire d´une ville qui, après la fin de l´esclavage et l´installation de la Republique, conserve des anciens préjugés de race et reste plongée dans l´immobilité economique. Le roman fait partie d´un ensemble d´oeuvres scientifiques et littéraires d´une géneration connue sous le nom de Novos Atenienses (nouveaux athéniens), laquelle discutait la crise économique et culturelle vécue par le Maranhão au tournant des XIXe et XXe siècles. Le discours formulé par les nouveaux-athéniens comprennait des eléments nostalgiques associés au culte des lettres envisageant la conquête de la réconaissance littéraire et le désir d´adapter la ville de São Luis aux modèles de progrès et modernisation de la période républicaine. Dans ce contexte, Moraes introduit les thèmes liés à la discrimination raciale qui demerait après la fin de l´esclavage, qu´il considérait un obstacle au progrès de la capitale de Maranhão, et aussi la cause des pérsecutions littéraires dont il était victime. On a analisé le roman en cherchant compreendre les rapports entre les individus et les rapports qui´ils entretienent avec les spaces de la ville, à partir de questions d´ordre littéraire, raciale et urbaine. En guise de conclusion, la narration de l´oeuvre est dévellopée de façon que la ville, peuplée de gens de couleurs, sert à legitimée l´oeuvre littéraire de Moraes, dont le nom a été oublié dans les principaux cercles littéraires de la capitale pendant la période examinée

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

A Família do tesouro: a monumentalização da família Albuquerque Maranhão e a luta pelo poder no Rio Grande do Norte (1889-1914)

The objective of this study is to discuss the process of building a family monumentalization Albuquerque Maranhão showed that both the traditional historiography of Rio Grande do Norte, represented by Tavares de Lyra, Rocha Pombo e Câmara Cascudo, as reflected in urban areas of Natal. To understand this process, we intend to analyze the production of the aforementioned authors as well as more recent studies, trying to discern or identify an attempt to link them to the family name to the history of Albuquerque Maranhão State, which ended up giving visibility to this group, making it the characters featured in the scenario of local history, investing them with a monumental character. In addition to historical analysis, we observe changes in the urban landscape of the city of Natal in the early twentieth century orchestrated by members of this family, which tied his line to public spaces for a new and modern city. Through this review, we will be able to realize that such practices turned out to be a stage of political disputes between Albuquerque Maranhão and opposition groups who were anxious to remove them both from the center of historical narratives on the Rio Grande do Norte, as well as the political space of the State environment exclusive domain of this group for nearly twenty years

A Praça André de Albuquerque, Natal/RN, na visão de seus frequentadores

The study offers a global and interpretative view of the person-environment inter-action at André de Albuquerque Plaza, in Natal, RN, according to a descriptive-exploratory approach that aimed at learning about the space converted into place, as it is perceived and experienced by users, who attribute meaning to it. The main objective was to critically analyze the relationship person-plaza, based on data collected about users perception, utilization and ascribed meaning. I have employed an Environmental Psychology multi-method approach, including informal observations, interactive poster session, videotaping and interviews. The results indicated that the plaza, besides being a passage point, is also a spot of urban convergence for several groups, particularly taxi drivers, flanelinhas, skate boarders and students. In regard to the perception of the place, an overall positive evaluation of the plaza was verified, since people perceive selectively what interests them. In terms of usage, different groups of users presented diverse patterns of utilization, also observed in the attributed meanings. The plaza is a work place for taxi drivers and flanelinhas and a sports arena for the skate boarders, with a practical meaning for both groups. For students and other users it is a place for meeting and leisure, revealing a stronger affective quality, responsible for feelings of well being, tranquility and relaxation. The data so obtained could contribute for future government projects of intervention in those spaces, aiming at its preservation as an open spot among the concrete of city buildings, offering better quality of life, not only for today, but also for future generations

Risco de queda em idosos da comunidade: avaliação com o teste Timed up and go

Risco de queda em idosos pode ser avaliado por meio de um teste simples de mobilidade. OBJETIVO: Avaliar o equilíbrio de idosos usando o teste Timed up and go. MÉTODO: Os indivíduos tiveram o tempo medido desde o momento em que se levantaram de uma cadeira, caminharam 3 metros para a frente e retornaram à cadeira. Os idosos também responderam questões sobre desequilíbrio, tontura e queda. RESULTADOS: Cerca de 69% dos sujeitos realizaram o teste em até 19 segundos. Houve correlação significativa entre desequilíbrio, tempo dispendido e queda, assim como entre tontura e queda. CONCLUSÃO: A maior parte dos idosos mostrou baixos valores no teste, o que sugere boa mobilidade funcional. Entretanto, um número expressivo de indivíduos com valores mais elevados estão, provavelmente, mais propensos a quedas e à dependência menor ou maior nas atividades da vida diária.
