Estudo do crescimento, eficiência de biofiltração e cinética de absorção de nutrientes (N-NH, N-NO e P-PO4³) da macroalga Gracilaria cervicornis (Turner) J. Agardh

The objective of this study was to examine the growth of Gracilaria cervicornis cultured in a shrimp (Litopenaeus vannamei) pond and to determine the absorption efficiency and the kinetics parameters (Vmax, Ks e Vmax:Ks) of this macroalgae for the nutrients N-NO3-, N-NH4+ and P-PO4-3, aiming at its use as bioremediatory of eutrophicated environments. For this study, two experiments (field and laboratory) were developed. In the field study, the seaweed was examined in relation to the growth and the biomass. In the laboratory experiment, the absorption efficiency of G. cervicornis was measured through the monitoring of the concentration of the three nutrients (N-NO3-, N-NH4+ e P-PO4-3) during 5 hours and the kinetic parameters were determined through the formula of Michaelis-Menten. The results obtained in this study demonstrated that G. cervicornis benefited from the available nutrients in the pond, increasing 52.4% of its biomass value after 30 days of culture. It was evidenced that the variability of the biomass could be explained through the salinity, availability of light (transparency and solid particle in suspension) and concentration of N-NO3- in the environment. In the laboratory experiment, the highest absorption efficiency was found in the treatments with low concentration (5 µmol.L-1), being evidenced a reduction of up to 85,3%, 97,5% and 81,2% of N-NH4+, N-NO3- and P-PO43-, respectively. Regarding the kinetic parameters, G. cervicornis presented better ability in absorbing N-NH4+ in high concentrations (Vmax = 158,5 µmol g-1 dry wt h-1) and P-PO43- in low concentrations (Ks = 5 µmol.L-1 e Vmax:Ks = 10,3). The results of this study show that G. cervicornis could be cultivated in shrimp ponds, presents a good capacity of absorption for the tested nutrients and is a promising candidate for biorremediation in shrimp pond effluent

Museu vivo : uma análise do Museu Câmara Cascudo

This work was developed from the research field in the Museu Câmara Cascudo (MCC) and the theoretical research in Museum Studies, enlarging the idea of museum while ambience of culture. We believe that the MCC, located in the city of Natal RN, is a relevant sociocultural institution because it is a university museum, because it was created two years after the foundation of the Universidade Federal do Rio Grande do Norte, and because it develops researches and studies about man on his physical and cultural aspects. Thus, this work is made up by a reflection on the transient and mobile aspect of culture living culture to understand the role of the museum in contemporary society. The MCC analysis, including its history, its functioning, its main activities, and its expositions, illustrates one part of our investigation. The other part is composed by theoretical consideration made from the reading of authors such as Bauman, Lévi-Strauss, Morin, Kristeva, Foucault, Le Goff, among others

Juventude universitária nos anos 1980: as práticas culturais do movimento estudantil na UFRN

The 1980s, at UFRN represented a moment of resumption of student struggles. The major goals of the student movement in this period was the fight against the authoritarian regime and for the democracy within and outside the university. In this context, events, activities, artistic and cultural productions were organized in order to make a critical policy for the procedure, trying to establish a dialogue between the university community and the population. Our work has made a research on cultural practices of the student movement in the 1980s. We did an analysis on the process of democratic transition in Brazil, the political participation of youth, their cultural practices in the country, society and politics in the RN, the student movement at UFRN and its cultural practices. We also discussed the concept of culture and cultural practices, but also pointed each of the the main activities and cultural productions organized by students of UFRN in that period. As methodological resource, were used the oral sources, the academic literature on the subject and newspaper pieces, newsletters and advertisement material of the students

Dadi e o teatro de bonecos: memória, brinquedo e brincadeira

The puppet theater is the theme of this dissertation, with a particular treatment of Memory, Toy and Jokes, focused especially on a Calungueira, maker of dolls, Ieda Maria Medeiros da Silva, known by Dadi. Currently with 71 years old, Dadi resides in Carnauba dos Dantas / RN and not only restricted to "get" the dolls to play, to enact stories by various characters. Build the dolls, dresses, give life, movement. In Rio Grande do Norte, the Puppet Theater, named "João Redondo," is measured by a historically male character of tradition, represented by some masters who have died or by their pupils, or even by the players who have no lineage of masters in their families but learned from several of them and, gradually, were included in this playful universe. Dadi passes this potiguar genealogy and going to suggesting a variety of transgressions, beyond, with its inventiveness, both in their presentations and in her life, which I did elect her and choose as a singular object in the course of my inquiries. In this study, I use the theoretical and methodological framework of social sciences, in particular the references coming from studies of culture, such as approaches of memory and tradition of authors such as Maurice Halbwachs and Paul Zumthor, among others. The field work was systematized, prioritizing the observation participant and permanent dialogue. I used different strategies for registration, as semi-open interviews, documentary video, audio narratives, photographic and videographic record, giving the work a current relevance to the dialogue with various elements, expanding the initial project, which turned into research for the dissertation

Políticas Culturais e Gestão Cultural: a Secretaria Municipal da Cultura e do Turismo SEMUC (2005-2010) de Limoeiro do Norte-CE

The study analyzed regarding cultural policies developed in the city of North-EC Limoeiro by the Municipal Culture and Tourism (Semuc) in the period between the years 2005 and 2010. Period that marks the resumption of the figure of the State Ministry of Culture (MinC) as a major factor in formulating and implementing public policies in the area of culture in the country, especially with the creation of the National Culture System (CNS) and the preparation of National Culture Plan (NCP). The work was through research documents (laws) about what had legislated on culture in the city, the reports of consultation activities undertaken by Semuc and interviews with former managers, a former - employee and the Secretary of that folder. Thus, given the contemporary context where the culture is replaced by increasing visibility, the analysis undertaken on policies developed by cultural Semuc revealed the most diverse forms of action: investment in events (capture and promotion), the institution permanent cultural policies, cultural background, the appreciation of local culture, and specific actions

A imagem da pessoa comum: sobre os filmes dos pontos de cultura de natal/rn

The following research aims to address the image of the ordinary person in the films of the Pontos de Cultura (Culture Points) in Natal-RN. About ten years the Federal Government of Brazil created the Cultura Viva (Living Culture) program. It enabled the State to support financially civil society organizations that had developed cultural works in communities across the country. Along with the resources the program developed, in parallel, another action, Cultura Digital (Digital culture), intended to bring the tools of digital technology for people who have never had access to them. As a result of these initiatives were produced short films. These films were characterized by the presence of the image of the ordinary person. The creation of this type of cultural product was benefited by state initiative, however, it was inserted within a historical, political and cultural construction whose research was necessary for this image understood to be understood by its importance: it is the expression of emancipation the ordinary person and not just as a consumer of culture, it identifies them as the protagonists of the society and recognizes their vital role in its organization

Narrativas do Brasil nas memórias de Pedro Nava

This thesis is a translation of work of the Brazilian doctor, Pedro da Silva Nava (1903-1984), in particular, his memoirs and chronicles, articulated with the writings of medicine history, aiming to defend that the autobiographical narratives are sources of research capable of promoting discussions on the expansion of the present at the confluence of complex and unequal society in constant changing process as the Brazilian. The theoretical and methodological support circulates around studies, proposals and thesis by Boaventura Santos about empowering past, destabilizing subjectivity, sociology of absences, cosmopolitan reason and translation work. The empirical support drawn from the literature produced by Nava were analyzed with reference this reasoning and studies that have facilitated the flow of translation among others, the studies of Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecléa Bosi, Ítalo Calvino, José Willington Germano, José Maria Cançado, Lev Vygotsky, Marilena Chauí, Paul Ricöeur and Walter Benjamim, without neglecting what we consider indispensable to scientific research, the production of relevant knowledge and prudent, in view of a decent life. The initial inflections reflect the subject of the Memoirs and its education/training, to then place the Memoir subject in the literary context, scientific, historical and Brazilian poetic (1972-2010), bringing great interpreters and discussing the rationale used by the Narrator that we defend stand closer to the cosmopolitan, showing the formation of narratives whose presence insert itself beforehand to modernist verve, linked to the discursive array against the literature as domination space, disseminated in Brazil in the early twentieth century. So, it articulate with those in which the concerns adjust the construction of the social formation of Brazil as a national heritage through literary narrative that focuses on a historical principle that becomes the past empowering, allowing his rereading, whose converge to memory, the lifestyles, the plurality of language and Brazilian culture, formed by several people, converging into a design not of culture but multiculturalism in Brazil. The memory issue was addressed in the space-time of experiences of being that narrates, shaped by a destabilizing subjectivity that sought to order the testimony of a time, a history and society, retelling them by creative imagination, almost fictional, to make circulate his knowledge about Brazil attached to his medical knowledge, as well as other subjects in his living group and other groups with whom they maintained contact. Thus, he portrayed both tangible and intangible cultural assets of the country as a form of preservation, giving them meanings and sense. It approaches, therefore, from the perspective of sociology of absences, the expansion of the present and by the logic inherent in his narratives of self and Brazil

Antonin artaud: a crueldade pelos desenhos e autorretratos

Antonin Artaud, a name that reminds us of areas ranging from theater to poetry, linguistics to psychoanalysis, is a multipurpose name that transits as poet, painter, writer, actor, screenwriter, playwright and theater director. Artaud s route is raw material for researchers of various hues interested in a life and work that allows panning in different fields of knowledge. It raises the question of language and manipulation of signals in terms of magical forces and the relationship maintained through them with the cosmos and the divine. Artaud searches through a language of signals, gestures and objects that express themselves by objective forms and the use of words as solid objects. For him, the language of words must give way to the language of signals, whose objective aspect is what strikes us most immediately. Our work indicates the possibility of realization and recognition of the aesthetic of cruelty present in the writing drawings of artaudian s work, realizing thus, that art as a record of culture hence as double of life allows us a more critical and transforming look to the society, thinking about the aesthetics of cruelty as Artaud proposes and thinks cruelty: as appetite for life. Our dialogue held during the construction of this journey has the company, besides the one of Antonin Artaud, other authors such as Jacques Derrida, Gilles Deleuze and Felix Guatarri, among others which, during the hike and framing of this route help us to think about the aesthetics of cruelty in an Artaudian perspective

Novas fronteiras petrolíferas no Brasil : uma análise da necessidade de nova regulamentação da área do pré-sal sob a ótica constitucional

The Oil industry in Brazil has gone through several stages during the economical, political and social historical process. However, the significative changes have happened in the last fifteen years, due to market opening arising from the relaxation of the state monopoly over the Oil deposits and its derivatives. The edition of the Constitutional Amendment #9, changing the first paragraph of the 177th item of the Federal Constitution, marked the end of a stiffness about the monopoly that the Brazilian state kept in relation to the exploration and research of Oil and Gas. The economical order was fundamental to actualize the idea contained in the #9 Amendment, since its contents has the power to set up measures to be adopted by public power in order to organize the economical relations from a social viewpoint. The new brazilian Oil scenery, called pre-salt, presents itself in a way to amaze the economical markets, in addition to creating a new perspective to the social sector. This work will identify, in this new scenario, the need for change in the legal system. Nevertheless, this subject must not be treated in a thoughtless way: being an exhaustible good, we shall not forget that the future generations also must benefit from the exploration of natural resources recently discovered. The settlement of a new regulatory mark, including the change in the concession contract model to production and sharing is one of the suggested solutions as a bill in the National Congress, in an attempt to ensure the sovereignty of the nation. The constitutionality of a new regulatory mark is questioned, starting from an analysis of the state monopoly, grounding the comprehnsions in the brazilian constitutions, the relevance of the creation of Petrobras for self-assertion of the state about the monopoly of Oil and derivatives, and its posture after the Constitutional Amendment nº 9 (1995), when a company stops having control of the state monopoly, beginning to compete in a fairly way with other companies. The market opening and private initiative are emphasized from the viewpoint of the Constitutional Principles of the Economical and Social Order. The relaxation of the monopoly regarding the exploratory activity in the Federal Constitution doesn't deprive from the Union the ownerships of underground goods, enabling to this federal entity to contract, directly or by concession of exploration of goods, to state-owned or private companies. The existing oil in the pre-salt layer transforms the scenario from very high risk to low risk, which gives the Union the possibility of defining another way of exploring this resources in the best interests of the Public Administration

Uma educação tecida no corpo

In theory say the education as a knot of meanings made in the body. We take as a reference for demonstration of this argument the shows Folguedos, Guarnicê and Flor do Lírio and built within such spectacles cultural, symbolic and aesthetic meanings, which reveal the education woven in the body. Education that can happen not only in the formal space like the classroom or the university, but also in the area of art and the inclusion of individuals in the world of culture. So during the construction of the thesis we reflect on the following issues: what is the construction of culture and art that have in the Parafolclórico group? What way theses shows in their buildings bring significant elements that might compose an educational activity. How objectives sought asking the dichotomies present in the concepts of art and culture; critically systematize a work of artistic, cultural and educational production in the group, in addition to expanding the understanding of education, considering the body experiences. The phenomenological attitude of Merleau-Ponty, is a reference methodology of this study, which places the reference knowledge as a result of our experience in the world, our world lived. Thus, this study considers the experience of the researcher in the three shows in tariff, represented by scenes described, as a dancer and spectator. Therefore we understand that Folguedos, Guarnicê and Flor do Lírio in their artistic, aesthetic and cultural languages, allow many meanings that occur in the body, which invites the perception and extend the experience of the subject, demonstrating an education that allows sight and knowledge, seeking new sensations and experiences, we show our intimacy with the world, with the objects and with the other. The art is understood as virtuality, as a human creation that carries the reality and that allows many readings and experiences, each perception can recognize and know new horizons, having as base and material the culture. This entails the heterogeneous, is not closed but that individuals can interpret it entered and recognize the symbols they created the same way, confirming a unit. The art and culture show us significant evidences of an education woven in the body

A formação do professor alfabetizador em cursos de Pedagogia: contribuições e lacunas teórico-práticas

To the we assume the disciplines of the area of Literacy of the course of Pedagogy, our intention has been the one of working the literacy, the reading and the writing as alive processes, as social practices inserted in the history, continuators of the subjectivity, done in the culture and producing of culture. The importance of the course of Pedagogy in the teachers' formation is unquestionable; however our goal is to highlight, in this work, the paper of that course in the formation of the teacher alphabetized, while mediator of the literacy process with an inclusive vision. In that to walk, it appeared us the following subject: which the contributions and the gaps theoretical-practices - of degree courses in Pedagogy - experienced for the exits of that course, in the specific pedagogic work of alphabetizing children, young adult and/or our study aims at to investigate, under the perspective of teachers alphabetizer licensed in courses of Pedagogy, the contributions and the theoretical-practical gaps of those courses, in the formation of the educator alphabetizer. In this sense, our work if it bases on the presuppositions of the qualitative investigation that leaves of the foundation that there is a dynamic relationship among the real and subjective world, an alive interdependence between subject and object, an entail indissoluble between the objective world and the subjective (CHIZZOTTI, 1998, p.79). The research is characterized as a descriptive and interpretative study and for the collection of data; the questionnaire, the semi-structured interview and the documental analysis were used. We took the following providences for the choice of Locus and of the subject of the research: it visits to the schools; compatibility of the criteria previously defined for choice of Locus and of the Subjects. For the choice of those schools, we defined the following criteria: that, in your individuality / totality, they were located in integral neighborhoods of, at least three of the four administrative areas of the city of Natal; that, in your individuality / totality, they contemplated the public spheres and private of attendance; that, in the year of accomplishment of the research - 2004 - they were offering infantile education and/or fundamental teaching; this last one gone back to the children of the initial years and/or for the youth and adult of the first levels of the modality of EJA; and that made possible the researcher's access. Front to the particularities of our study object and considering the criteria of choice of the locus, four public schools and three private schools were selected. Like this being, in those schools, we would look for the subject of our work that they would owe: 1) to be working, in 2004, with children's literacy, youths or adults: they as teacher (the), it as coordinator (the) that guides teachers alphabetizer, in public schools or peculiar of the city of the Natal-RN; 2) to be exit (the) of the degree course in Pedagogy, supplied by institutions of superior level (public or matters) of the city of the Natal-RN; 3) to have concluded your course of Pedagogy in the period of 1990-2004; 4) to have, at least, 01(one) year of experience in literacy rooms (TARDIF, 2002). The subjects interviewees concluded your courses of Pedagogy, in the period from 1990 to 2004, in institutions different from the city of Natal/RN, being five to the whole: two public IES and three deprived IES. Of the analysis of the data, the theme emerged, ' teacher's Alphabetizer Educational Formation in Courses of Pedagogy', with the following categories: contributions of the courses of Pedagogy; More important disciplines in the educational formation; Areas / Aspects lacunars of the courses of Pedagogy. The pedagogic practice of the teacher alphabetizer demands a formation from him found in you know educational, requested in the children's literacy, youths and adults. In that work, we defended the thesis that the course of Pedagogy is the locus, par excellence, for that formation, in spite of possible structural limitations and curricular of the referred course. In spite of the countless contributions of the pedagogy course for the formation of the teacher alphabetizer, our data appear for the need of a revision of the proposals curricular of that course, getting the attention for the importance of a proposal formation curricular more gone back to the literacy process / literate and for the social inclusion. We thought that, although insufficient, the teacher's formation in that perspective is a fundamental condition for a practice pedagogic alphabetizer to be promoted, in fact, inclusive and promoter of the school success

Fecundação in vitro de ovócitos bovinos com sêmen submetido a diferentes diluidores

O objetivo deste trabalho foi avaliar a influência do diluidor do sêmen no desenvolvimento in vitro de ovócitos bovinos após a maturação e fecundação in vitro. Ejaculado de um reprodutor foi fracionado e submetido a três diluidores: Lactose/gema de ovo (LG), Citrato/gema de ovo (CG) e Tris/gema de ovo (TG). Amostras deste material foram envasadas, congeladas e estocadas em N² e, posteriormente, descongeladas; a fração móvel foi separada por gradiente descontínuo de Percoll. A concentração espermática foi ajustada para 10 x 10(6)/mL e a capacitação espermática, induzida com 10 µg/mL de heparina. Após 24 horas de cultura para maturação in vitro, os ovócitos, aspirados de folículos ovarianos, foram inseminados com sêmen diluído em meio TALP e, após 48 horas de cultura, os zigotos foram transferidos para gotas de meio TCM 199, com 5% de soro fetal bovino, 5% de soro de vaca em estro e suspensão de células epiteliais do oviduto bovino, cobertas com óleo de silicone, e mantidos em cultura por nove dias. Todas as culturas foram realizadas a 38,5ºC em atmosfera com 5% de CO2. Os dados foram analisados pelo teste do qui-quadrado e houve diferença com relação à taxa de clivagem (TC), sendo as médias de 66,0; 69,3; e 54,4% para LG, CG e TG, respectivamente. Não houve diferença entre tratamentos com relação às taxas de mórulas/blastocistos ou de eclosão. O diluidor do sêmen não teve efeito sobre o desenvolvimento in vitro de embriões bovinos, embora a TC tenha sido afetada.

Itinerário educacional de uma aluna cega e a busca pela imagem adaptada

The scope of this study directs an investigation in search of how the blind person learns knowledge at school mediated by the image in context of an inclusive education and how it can be (or is) triggered by the adaptation of images to the tactile seizure of the blind person and his correlative process of reading. To achieve this intent we choose a qualitative approach of research and opted for the modality of case study, based on the empirical field of a public school in the city of Cruzeta, RN and as a the main subject a congenitally blind female student enrolled in high school there, focusing, often, on the discipline of geography in its words mapping. Our procedures for construction of data are directly involved to the documentary analysis of open reflective interview and observation. The base guiding theory of our assessments is located in the current understanding about the human psychological development of its educational process inside an inclusive perspective, of contemporary conceptions about the visual disability as well of image as a cultural product. Accordingly, the human person is a concrete subject, whose development is deeply marked by the culture, historically built by human society. This subject regardless of his specific features, grasping the world in an interactive and immediate way, internalising and producing culture. In this thinking, we believe that the blind person perceives in multiple senses the stimuli of his environment and acts in the world toward his integration into the social environment. The image as a product of culture, historically and socially determined, appears as a sign conventionally used as an icon that in itself concentrates knowledge of which the student who does not realize visually himself and his surroundings cannot be excluded. In this direction, the inclusive educational process must build conditions of access to knowledge for all students without distinction, including access to the interpretation of the images originally intended for the seizure strictly visual to other perceptive models. Based in this theory and adopting principles of content analysis, we circulated inside the interpretation of the data constructed from the analysis of documents, from the subject speeches, from records of the observation made in the classroom and other notes of the field daily. In the search for pictures on the school contents, adapted to the tactile seizure of blind student, was seen little and not systematic in practice and teaching at the school. It showed us the itinerary of the student life marked by a succession of supports, most of the time inappropriate and pioneers in cooling the construction of her autonomy. It also showed us the tensions and contradictions of a school environment, supposedly inclusive, that stumbles in search of its intent, in the attitudinal and cumulative barriers brought, because of its aggravating maintenance. These findings arose of crossing data around of a categorization that gives importance to 1) Concepts regarding the school inclusion, 2) Elements of the school organization, educational proposal and teaching practice, 3) Meaning of the visual image as the object of knowledge, 4) Perception in multiple senses and 5) Development and learning of the blind person before impositions of the social environment. In light of these findings we infer that it must be guaranteed to the disabled person removal of the attitudinal barriers that are against his full development and the construction of his autonomy. In that sense, should be given opportunity to the student with visual disability, similarly to all students, not only access to school, but also the dynamics of a school life efficient, that means the seizure of knowledge in all its modalities, including the imagery. To that end, there is a need of the continued training of teachers, construction of a support network in response to all needs of students, and the opportunity to development of reading skills beyond a perspective eminently focused in the sight
