Filhos da independência: etnografando os estudantes Bissau-guineenses do PEC-G em Fortaleza-CE e Natal-RN

Notre travail propose de comprendre l`immigration africaine contemporaine du Brésil à travers l'univers des étudiants guinéens participant au Programme Étudiants « Convênio de Graduação » (PEC-G) dans les villes de Fortaleza dans l'Etat Ceará et Natal dans l'Etat de Rio Grande do Norte, en étudiant leurs stratégies de convivialité et d'adaptation. Les étudiants étrangers sélectionnés dans ce programme font leur licence gratuitement dans les Instituts d'Enseignement Supérieur (IES). Pour accéder à ce programme ils doivent répondre à certains critères : montrer qu'ils sont en mesure de payer leurs frais au Brésil, avoir le bac ou un diplôme équivalent et maîtriser la langue portugaise lorsqu'ils sont originaires d'un pays n'appartenant pas à la Communauté de Pays de Langue Portugaise (CPLP). Les étudiants qui participent à des programmes de développement socio-économique contractés entre le Brésil et leurs pays d'origine sont prioritaires. Ces accords les contraignent à rentrer dans leurs pays d'origine et de travailler dans le domaine dans lequel ils ont été diplômés une fois les études terminées. Les étudiants, qui arrivent au Brésil porteurs de leurs identités ethniques guinéennes, entrent en contact avec la société brésilienne et acquièrent ainsi une « identité hybride ». C'est dans ce contexte que ce travail analyse le quotidien des étudiants africaines au Brésil avec un regard porté sur les étudiants de Guinée-Bissau à Fortaleza et à Natal comprendre l'expérience des étudiants qui vivent en terre étrangère. Ainsi, le lieu (Brésil) prend toute sa valeur par rapport au distant (Guinée) autrefois lié par l'histoire coloniale et aujourd'hui lié par des relations internationales ou diplomatiques. Finalement, la construction d'une « nouvelle » identité ethnique, d'une culture guinéenne au Brésil s'opère dans une célébration mobile c'est-à-dire successivement formée et transformée en relation avec les formes à travers lesquelles l'individu est représenté ou interpelé dans les systèmes culturels dans lesquels il est impliqué.

Síntese e caracterização de peneiras moleculares mesoporosas do tipo MCM-41 e AlMCM-41 a partir de fontes alternativas de sílica e de alumínio

The mesoporous molecular sieves of MCM-41 and AlMCM-41 type are considered as promising support for metal in the refining processes of petroleum-based materials as catalysts and adsorbents for environmental protection. In this work the molecular sieves MCM-41 and AlMCM-41 were synthesized by replacing the source of silica conventionally used, for quartz, an alternative and abundant, and the use of waste from the production of diatomaceous earth, an aluminum-silicate, as a source aluminum, due to abundant reserves of diatomaceous earth in the state of Rio Grande do Norte in the city of Ceará-Mirim, with the objective of producing high-value materials that have similar characteristics to traditional commercial catalysts in the market. These materials were synthesized by the method of hydrothermal synthesis at 100 º C for 7 days and subjected to calcination at 500 º C for 2 hours under flow of nitrogen and air. The molecular sieves were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA) and thermogravimetric analysis (TG), adsorption of N2 (BET and BJH methods), spectroscopy in the infra red (FTIR), microscopy scanning electron (SEM) and transmission electron microscopy (TEM). The analysis indicated that the synthesized materials showed characteristic hexagonal structure of mesopores materials with high specific surface area and sort and narrow distribution of size of pores

A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

A Relação professor-aluno e a afirmação do discente como sujeito do processo projetual: um estudo exploratório sobre a produção do trabalho final de graduação em arquitetura e urbanismo na UFC e na UFRN

This work deals with teacher-student relationship (TSR), held in a very special moment: the semester of graduation of architecture and urbanism, where students prepare the final work called Graduation Final Work (GFW). That is the last stage to obtain the title of architect and urban planner in Brazil. The text discusses this problem in several ways, emphasing the relationship between graduated student and his/her mentors into the consolidation process of the student as an actor of the planning process, here defined as "autonomy". The work is focused on understanding the TSR in order to elucidate its importance for improvement of teaching bases on development of the GFW, more than the relation between curriculum and institution. Related with the exploratory characteristic of this master thesis, methodologically, the field work happened through: (i) observation of mentorship guidance, (ii) interviews, and (iii) application of questionnaires to teachers and students. Participated 10 pairs of student and mentors of two federal university of Northeast: 05 pairs of the Federal University of Ceará (UFC) and 05 pairs of the Federal University of Rio Grande do Norte (UFRN). The results presented the development of the GFW as a difficult process / fearful for students, highlighting the main problem situations: the difficulty in choosing the theme, the super-sizing of the process, students' insecurities, and parental relationship with the supervisor process. Summing up, the work indicates that the students has a limited autonomy on the GFW process, which calls for a revision in order to promote the consolidation of the student autonomy, which must be observed for some positions recognition of the role of each actor in the process of orientation

Barracas de Praia, praia de barracas: configuração, tipo e usos na praia do futuro, Fortaleza CE

The purpose of this dissertation is to analyse the importance of the huts of Praia do Futuro to their users and to the city of Fortaleza in Ceará through the comprehension of relations between morphological categories - in urban and edified contexts - of the establishments and their use patterns. This place is one of the main recreation and leisure areas of the city, formed by six kilometres of waterfront, corresponding to a differentiated area through the coast. This space has beach huts with varied profiles: while some more simple huts persist, great complexes are being developed, building even water parks on the beach area. This study analyses relations between:i) spatial configuration (in geometric and mainly topological terms) based on the Social Logic of Space; ii) edified typology (analysing capacity, landscap treatment and program of the huts); and iii) use and environmental perception of the beach by its frequenters. There are consistent relations between the type of hut and their localization in the urban grid, of which were identified groups with different patterns: segregated (north, central and south) and integrated (north: more integrated. and south: less integrated). Such relations also reflect, in varied patterns of use and environmental perception. In spite of their strong economy, the beach huts find themselves in a fragile legal situation because they occupy the beach area, so that this study may come to assist the decision-making for the future of the region. For a sustainable development of the area by those responsible and managers it is necessary to evaluate the cultural importance of the huts at Praia do Futuro, understanding their occupation and uses.

Entre serras e sertões A(s) (trans)formaç(ões) de centralidade(s) da Região Metropolitana do Cariri/CE

This study reviews the spatial configuration from the road network of an urban compound formed by the cities of Crato, Juazeiro do Norte and Barbalha (the Crajubar - core of the Cariri metropolitan region, in the State of Ceará, Brazil), in order to establish nexus (or relations) between different levels of accessibility and the formation/ transformation and specialization of centralities in local and metropolitan scales. Stemming from the Social Logic of Space theoretical and operational apparatus, the study explores modeling possibilities (with axial lines, segments and lines of continuity) which is then confronted to empirical observations concerning movement flows and land use, within a Geographic Information System database. At different scales of analysis, the results suggest evidences of continuity were found in the permanence of intra-urban centres and sub-centres within each town, whereas evidences of change pointed out to the formation of a new centrality of metropolitan magnitude in the neighbourhood referred to as the Triângulo, in the municipality of Juazeiro, where high levels of topological accessibility coincides with the appearance of new business buildings as well as with the emergence of urban equipment of a scale more adequate to meet a regional demand

Efeito da utilização do Kit Embrapa de Ordenha Manual® para caprinos leiteiros na Contagem Total de Bactérias do leite.

Resumo: A produção de leite de cabra no Brasil destaca-se no Nordeste, onde as condições de criação e os programas governamentais favorecem a produção. A qualidade higiênico-sanitária do leite de cabra, além de ser uma característica indispensável ao produto, exigida pela legislação Brasileira, contribui para diminuição nas perdas econômicas decorrentes da mastite e para a manutenção dos produtores na atividade. O Kit Embrapa de Ordenha Manual® para caprinos leiteiros é um conjunto de utensílios e práticas indispensáveis para a obtenção higiênica do leite de cabra, o qual apresenta-se como uma alternativa viável aos agricultores familiares devido à sua facilidade na utilização e baixo custo de aquisição. O Kit foi implantado e validado em 41 propriedades familiares, localizadas nos estados do Rio Grande do Norte, Paraíba e Ceará. Procedeu-se a coleta de leite de cabra 3 dias antes e 3 dias após a utilização do Kit, para a realização da Contagem Total de Bactérias (CTB). Observou-se uma redução média de 72% da CTB no leite produzido, e, 95% das propriedades adequaram-se à CTB exigida pela legislação Brasileira. [Effect of the use of the Milking Manual® EMBRAPA Kit for dairy goats total count in milk bacteria]. Abstract: The goat milk production in Brazil stands out in the Northeast, where the breeding conditions and government programs favor the production. The sanitary hygienic quality of goat milk as well as being an indispensable feature to the product, required by Brazilian law, contributes to decrease in economic losses resulting from mastitis and to the maintenance of the producers in the activity. The Embrapa manual milking kit® for dairy goats is an essential set of tools and practices for obtaining hygienic goat milk, which presents itself as a viable alternative to farmers due to its ease of use and low cost. The Kit has been deployed and validated in 41 family farms in the states of Rio Grande do Norte, Paraíba and Ceará. The goat milking practice was carried out both three days before and three days after using the kit for the realization of Total Bacteria Count (CTB). There was an average reduction of 72 % CTB on the milk, and 95 % of the properties have adapted to the CTB required by Brazilian law.

Automação da drenagem no teste de produção convencional em tanque cilíndrico

This document aims to improve the quality of the production test in vertical tanks with free water drain pipes, through a device to control the draining system. This proposal consists of an interface detector close to the tank bottle and a control valve on the pipe-drain; they are attached to a remote supervisor system, which will be minimizing the human influence in the conclusion of the test result. And for more consciousness the work shows the importance of the wells production test in the attendance and diagnosis of the productive process, informing the large number of tests executed and problems of the procedure adopted in the field today. There are many possible sources of uncertainty in this kind of test as shown in the experiments realized in the field; the object prototype of this dissertation will be made in the field, based upon the definition of parameters and characteristics of the devices proposal. For a better definition of the draining process the action results of the assessment test are shown, especially changed some for the understand ing of the real process. It shows the proposal details and the configuration that will be used in the tank of Monte Alegre s field Production Station, explaining the interface detector kind and the control system. It is the base to a pilot project now in development, named as the new project classified in the status of the new technology and production improvement of PETROBRAS in Rio Grande do Norte and Ceará. This dissertation concludes that the automation of the conventional test with the draining system will bring benefits both economically as metrologically, because it reduces the uncertainty of the test procedures with free water draining, and also decreases the number of tests with problems

O Plano Diretor como instrumento de gestão da cidade: o caso da cidade de Fortaleza/CE

According to article 182 of the Brazilian Federal Constitution, cities should perform social function, what brings the concept that the city should be a place for one to live well. For that to happen, it should be well administered by its public managers. However, so that there is a sound administration, one that really performs that social function, there must be, first, an efficient planning. We understand that such a thing occurs when the master plan is the main planning instrument of a city and serves as basis for its administration. We notice, however, that in most of the cities the master plan is formulated as a law that regulates urban planning but that both the population and the government most of the times are not aware of its importance concerning the relevant issues related to municipal administration, such as its relationship with the economy, taxation, the social issue, land use regulation, and, in summary, with all the aspects that constitute and that a municipal government should manage in the best possible way. One also knows that, in general, the attempt of city planning has always been connected to the duration of a mandate and that way public managers many times implement restricted measures aiming to just attain a political-electoral objective and publicizing their administration. That implies actions and works that in some cases have negative impacts or ones that cannot be removed from the cities. This study intends to show that the master plan should be the planning instrument guiding the municipal administration but that, however, what we note is a lack of connection between that instrument and the government guidelines of the municipal managers. In order to study what happens to the cities that have a planning which is not taken into account in its administration, we will use the city of Fortaleza, capital of the State of Ceará as a case study. Historically, in Fortaleza the public managers have seldom decided to administer the city in according to the master plans developed for it. We should emphasize that planning begins in the city quite late and until the current days it is being substituted by temporary measures. Through the analysis of the planning process and of the urban management of the city of Fortaleza, especially the master plans predicted since 1933, we explain that if such plans had been implemented, they could have been important tools for its administration to attain a social function, becoming therefore a place for one to live well

A cena contemporânea aos pedaços : observação de um experimento pedagógico

We try to relate this research with other logic, to discover a path of practical approach to approach a creation composed of fragments and a search of parameters for the aesthetics of appropriation. Accordingly, we find relationship with the theater composed of fragments, where different styles are appropriate theatrical and representational styles are merged with each other. Discusses in the first chapter on the theater composed of fragments, and stroll through lanes of the strategies of some directors in the ways of the contemporary scene. In the second chapter we seek procedures and concepts of atmosphere Mikhail Tchekhov (TCHEKHOV, 1996), and the transition from point-to-point by Scott McCloud (2005). In the third part we describe the observation of the experiment conducted by the students of the Bachelor's Degree in Regional Theatre at the University of Cariri in Juazeiro, Ceará, in 2010. Using the methodology of "pesquisa-ação", observing that the scenic writing end of the experiment, called "Toque Me", and the presentation in the cities of Crato and Barbalha, in August 2010, contained elements of the strategies from theater fragmentary scenes and conceptual contents of contemporary theater
