Comunidade fitoplanctônica como discriminador ambiental em açude eutrófico tropical semiárido (Barragem Armando Ribeiro Gonçalves, RN) e divulgação científica para reflexão social

The knowledge of the phytoplankton community, as an integral and dynamic processes of eutrophication, provides information essential for proper management and handling. A growing problem of cyanobacteria in reservoirs around the world as a result of artificial eutrophication processes, generating a particular concern, because some species produce cyanotoxins, which can cause adverse effects on human health. The present work aims to characterize the spatial and temporal dynamics of phytoplankton, assessing their potential as ecological indicator of water quality in reservoirs semiarid region. The samples of water were collected monthly between 2009 and 2011, at three points along the dam Armando Ribeiro Gonçalves / RN. In each sample were measured physico - chemical analysis of water and biological components. We conducted a scientific dissemination activity, with distribution and reading primer on eutrophication, informative talk about water quality, questionnaires and performing a play in a public school in the city of Itajá / RN. The reservoir was considered eutrophic in three points, taking into account the values of chlorophyll -a and phosphorus, adopted to characterize eutrophic environments of semi-arid areas. High density of cyanobacteria, with a maximum value of 2.227.862 cél.ml- 1 and minimum of 43.456 cél.ml- 1 was recorded in lentic and semilêntico points throughout the study, exceeding the levels of drinking water (20.000 cél.ml- 1) established in 2.914/2011 Ordinance of the Ministry of Health of Brazil. All samples contained microcystin, and 44 % had values superiores1μg L- 1. The thermal pattern of the water column showed micro stratifications with differences of less than 1 ° C from five feet deep. The distribution pattern was the type profile clinogrado with oxygen deficit in the bottom of the reservoir. Oxiclina from 10 meters depth was observed during the rainy season (May-June) in the two years of study. The phytoplankton community was represented by 10 functional groups: S1, M, H1, Lo, P, F, Sn, P, W2 and R. The assessment of the ecological status of the system by the index Q showed poor water quality. The results of the study show that the vertical variations were less pronounced than the seasonal variations of cyanobacteria and phytoplankton community in general in the reservoir. The presence of cyanotoxins confirms the need for the monitoring of water quality and measures to reduce eutrophication in water supply reservoirs semiarid RN and demonstrates the challenge for water managers and health authorities to ensure water quality and consequently minimize risks to human health. Compared to the lecture, the primer was considered more efficient in sensitizing the participants, featuring a dynamic practice, differentiated learning, create opportunities for students to rethink attitudes of respect and care for the environment, and shall have the opportunity to learn the subject content from your reality and living environment. The knowledge generated from the activity of scientific were seen as essential for raising awareness of some of the region`s environmental problems , such as eutrophication

Biomonitoramento da qualidade da água e ações em educação ambiental em dois açudes da bacia hidrográfica Apodi-Mossoró, RN

Water scarcity is a reality for the inhabitants of the Brazilian semiarid region. The problem, in quantitative terms , is caused due to local climatic conditions due mostly to a water deficit. Qualitatively, results of multiple uses and resulting contamination by human activities. Eutrophication is presented as a threat to the sustainable use of water resources, in order to favor the predominance of dense populations of cyanobacteria, which can be potentially harmful to human health. The aim of this study is to understand the population dynamics of phytoplankton and cyanobacteria to assess water quality of reservoirs Santa Cruz do Apodi and Pau dos Ferros belonging to bacia Apodi Mossoró-RN . Water samples were collected monthly between October 2011 and May 2012 in reservoirs Santa Cruz do Apodi and Pau dos Ferros, in this latter , in Jan/12 we performed a diel profile . The abiotic variables obtained in the field and in the laboratory were: water temperature , dissolved oxygen , pH , turbidity , transparency , total nitrogen and total phosphorus . Phytoplankton samples were collected with a plankton net and bottle of Van dorn . Were performed : identification , quantification , calculation of biovolume , classification into functional groups and index calculation phytoplankton assembly ( Q ) , cyanotoxins were quantified by ELISA . Statistical analyzes supported the evaluation of the dynamics between biotic and abiotic factors. A questionnaire was conducted to examine the conceptions of the population, education professionals and students. The reservoir of Pau dos Ferros, shallow , turbid and eutrophic showed dominance of the functional group SN throughout the sample period . The phytoplankton biomass ranged from 20 to 70 mm ³ . L - 1, the lowest values coincided with the increase of the mixing zone and transparency, which contributed to the occurrence of a change in species composition phytoplankton . The application of the index Q proved relevant, the reservoir of Pau dos Ferros , depending on the species present , was classified ecologically as bad for almost the entire sample period . The reservoir Santa Cruz do Apodi showed low biomass ( 0.04 and 4.31 mm ³ . L - 1 ) and greater diversity in the phytoplankton composition . According to the index assembly (Q ), it showed moderate condition during most of the period influenced by different functional groups of typical meso- eutrophic environment (K S0, H1, C, F , J , E, D and N) . Associations of diatoms and green algae D and X1 succeeded populations of cyanobacteria in periods marked by greater instability in the system , caused by wind or rain. In summary , the occurrence of drought has a direct influence on the hydrological conditions of the reservoirs , in general, these events, reducing the reservoir level is directly related to decreased water quality and increased density of phytoplankton occurring predominance of cyanobacteria , the index Q reflected well to changes in phytoplankton composition , being a good indicator for biomonitoring of reservoirs in this study and survey of previous conceptions showed the need to work on environmental awareness for the preservation of water resources by conducting workshops for Environmental Education

Uma abordagem dialógica para a utilização de atividades experimentais em sala de aula

The belief of using experimental activities in the teaching of Physics as a strategy to produce a more efficient teaching-learning process is great among teachers and the school community. However, there are many difficulties for their implementation and when it happens they do not contribute for an improvement in class efficiency due to the method used. In this work, we developed a proposal for using these activities in Physics classes in high school, from a critical-reflexive approach in which the constant dialogue between the participants in the teaching-learning process is fundamental. The work was developed in two ways. The first, where the author/writer created an educational material and applied it in classroom and a second one, where he presented the idea to other teachers and undergraduate students from the Physics course at UFRN and IFRN (former CEFET-RN) through an extended workshop entitled "The role of experimental activities in the Physics teaching". This workshop had the duration of 60 hours and was implemented in 4 steps: i) sensitization and formation, ii) material development, iii) material implementation and iv) evaluation by teachers and students from the classes where the material was applied. The goal of this workshop was to present the approach, evaluate how the participants received the idea and how they would apply it in real situations. The results of the application in classroom allowed us to reach some conclusions. This approach was well received by the students as well as by the workshop participants. Despite some difficulties in relation to the handling of the implementation results by the workshop participants, they indicated changes in these professionals teaching practice and the introduction of experimental activities has been an important subsidy to assist them in Physics class in high school

Parâmetros bioquímicos e níveis de IgE total e específicas para aeroalérgenos em mulheres obesas com síndrome dos ovários policísticos

Introduction: Polycystic ovary syndrome (PCOS) whose classic features (menstrual irregularity of oligo/ amenorrhea type, chronic anovulation, infertility and hyperandrogenism clinical and/ or biochemical), is associated with aspects of metabolic syndrome (MS), as obesity and insulin resistance. The level of obesity determines different levels of inflammation, increasing cytokines participants of metabolic and endocrine functions, beyond modulate the immune response. Metabolic changes, added to the imbalance of sex hormones underlying irregular menstruation observed in (PCOS) can trigger allergic processes and elevation of total and specific IgE antibodies indicate that a sensitization process was started. Objective: To evaluate the influence of PCOS on biochemical parameters and levels of total and specific IgE to aeroallergens in obese women. Methods: After approval by the Committee of Ethics in Research, were recruited 80 volunteers with BMI ≥ 30 kg/m2 and age between 18 and 45 years. Among these, 40 with PCOS according to the Rotterdam criteria and 40 women without PCOS (control group). All participants were analysed with regard to anthropometric, clinical, gynecological parameters, interviewed using a questionnaire, and underwent blood sampling for realization of laboratory tests of clinical biochemistry: Total cholesterol, LDL-cholesterol, HDL- cholesterol, Triglycerides, Fasting glucose, Urea, Creatinine, Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and immunological: total and specific IgE to Dermatophagoides pteronyssinus, Blomia tropicalis, Dermatophagoides farinae and Dermatophagoides microceras.Statistical analysis was performed using SPSS 15.0 software through the chi-square tests, Fisher, Student t test and binary logistic regression, with significance level (p <0.05). Results: It was observed in the group of obese women with PCOS that 29 (72.5%) had menstrual cycle variable and 27 (67.5%) had difficulty getting pregnant. According to waist-hip ratio, higher average was also observed in obese PCOS (0.87). Blood level of HDL (36.9 mg/dL) and ALT (29.3 U/L) were above normal levels in obese women with PCOS, with statistically significant relationship. In the analysis of total and specific IgE to D. pteronyssinus high results were also prevalent in obese PCOS, with blood level (365,22 IU/mL) and (6.83 kU/L), respectively, also statistically significant. Conclusions: Observed predominance of cases with high levels of total IgE in the group of obese women with PCOS, 28 (70%) of the participants, whose mean blood concentration of the group was 365.22 IU/mL. In the analysis of Specific IgE between the groups, the allergen Dermatophagoides pteronyssinus showed greater dispersion and average the results of sensitization in the group of obese PCOS, whose mean blood concentration was 6.83 kU/l. Keywords: Obesity, Allergens and Polycystic Ovary Syndrome

A inserção do técnico em saúde bucal na estratégia saúde da família no estado do Rio Grande do Norte

An oral health technician is a profession in odontology whose own functions are defined in FEDERAL LAW NUMBER 11889, which can act for prevention, recovery and promotion of oral health. According to the web site, Of Primary Health Attention Department. Health Ministry Of Brazilian Federal Republic, you can see through historical cover, as regards Health Family Strategy that, in Rio Grande Do Norte, There are nowadays eight TSB equipments in use. Objective: The aim of this study is to find out the reasons of the inclusion of those technicians in public service, no matter the importance of this work. Method: It is about a quantitive study and a kind of exploring type, taking into account that there are not any similar previous ones. We divide it into two parts: as regards the first one, these technicians were registered in a map using the information of the Formation Schools and Class Counsel to know how and where they are. During the moment of this study, an application (or no application) of the mouth health equipments was done. They tried to discover in this process which elements contribute to the efficiency (or not) of this technical work done all together in equipment work. As regards the second part, the coordinators of Municipal Mouth Health answered to a survay that contained open and closed questions through telephone calls. The sample was defined by a raffle taking into account the work contained in municipalities. Results: There are 1053 technicians.94,3% of them are women, devided in all the health regions. As regards interview, 96,9% of oral health coordinators considered that it is very important to have an oral health technician in odontology. 92,2% would reccomend its inclusion in equipments related to mouth health, dealing to familly health . 76% have never talked before to the Health Secretary in this municipality. this spreading out could be related to financial resources and 51,6% mentioned the importance of improving the physical structure to make this spreading out possible. Conclusions: Oral Health technicians in Rio Grande Do Norte are not being adequatly used by public service, because they do not introduce themselves or act as Oral Health auxiliaries. It is important to increase concience about the importance of this category in odontology. we also say it is necesasary to invert money in a reform of the Basic Health Unities and the inclusion of these workers. On the other hand the role of the state and the public health militancy is questioned in the fulfilment of this process

Contribuição ao estudo avançado das argamassas de alto desempenho para reparos estruturais

Inúmeras estruturas de concreto no Brasil e no mundo estão atingindo o limite de sua vida útil projetada, completando um ciclo de cinco ou mais décadas de uso e operação. Além das estruturas mais antigas, existem ainda estruturas com reduzido tempo de serviço, e qualidade discutível, que já apresentam patologias em estado tão avançado que chegam a comprometer o seu desempenho. Vindo ao encontro dessas necessidades e no sentido de contribuir para o avanço científico e tecnológico do setor, este trabalho apresenta um método para dosagem, preparo e aplicação de argamassas de alto desempenho para recuperação de estruturas deterioradas, além de sugerir procedimentos para a realização desses reparos, fomentando a cultura das manutenções preventivas e desmistificando a complexidade atribuída a tais operações. Para tanto, foram realizados ensaios mecânicos, microestruturais e relacionados à durabilidade em corpos-de-prova moldados com sílica ativa e látex de estireno-butadieno. Os resultados indicaram que a adoção desses ingredientes, na composição da argamassa de reparo, provocou uma redução significativa da permeabilidade total e descontinuidade de poros, assim como promoveu uma melhor integridade dos constituintes da argamassa, traduzindo-se em uma ampliação, expressiva, das suas capacidades mecânicas. Quando comparada aos produtos industrializados da construção civil, com padrões similares, proporcionou uma economia da ordem de 85%, que permitiria recuperar, com os mesmos custos, quase cinco vezes mais estruturas comprometidas. Este estudo, de viés altamente tecnológico, vem oferecer à construção civil uma argamassa polimérica de alto desempenho, com função reparadora e custo mais acessível, que pode ser adotada em canteiros de obras, implementando ações de natureza sustentável e ainda atendendo às atuais exigências elencadas pela literatura, relacionadas à desempenho, vida útil e durabilidade das estruturas reparadas.

O que ser quer imagem, o que se quer desejo?: entre o fabular de desejos e as construções imagéticas na prosa de Fiama Hasse Pais Brandão

Este trabajo presentado, direccionado a la defensa de la disertación de maestría, intitulada ¿Lo que se quiere imagen, lo que se quiere deseo?: Entre el fabular de deseos y las construcciones imagéticas en la prosa de Fiama Hasse Pais Brandão, discute hasta donde el deseo impulse la imagen y hasta donde esta imagen es tocada por este deseo, visualizando dentro de un sistema literario poético y singular, las construcciones de la imagen junto a las fabulaciones de deseos, lo que nos expone delante de procesos de semiotización por medio de la escrita, de subjetivación, de vértigo, de sensibilización para los efectos y deseos en cuanto producción de sentido y multiplicidades estéticas en cuya letra transgresiva se aventura. En este sentido, el análisis transitará entre el discurso erótico y los problemas fundamentales que este pode, bien como el proceso de construcción de imagen, recortado por vía de discursos problematizados por el lenguaje presentado por la autora Fiama Hasse Pais Brandão. Para tanto, colocase como escopo una investigación norteada por autores como Bataille, Roland Barthes, Luiz Roberto Monzani, Suely Rolnik, Walter Benjamin, Georges Didi-Huberman, Maurice Blanchot, Félix Guattari, Gilles Deleuze, dentre otros que puedan transitar por las relaciones, en este estudio, establecidas, constituyendo el corpus teórico y de discusión, atendiendo al caráter cualitativo implicito en el desarrollo de esta disertación. Cuanto al corpus literario, este es compuesto por los contos trídos en Cuentos de la imagen (2005), de manera a constituiren cuerpo-subjetividad, envolviendo ideas, afectos, perceptos y imagens.

Música e surdez: o ensino de música numa perspectiva bilíngue na escola regular

The present study focuses on the development of pedagogical activities in Music Teaching, aiming to enhance the accessibility of musical knowledge for both deaf and hearing students, using a bilingual approach in regular schools. Few studies address Music and Deafness, and those that do focus exclusively on the context of special education, and specifically the deaf student, which signals the urgent need for conducting research on this issue in the context of inclusion – empirically and carried out on school grounds. Therefore, we developed our study at a Natal City Public Elementary school, in a class of 6th graders, comprised of 37 students, 3 of whom were deaf. The objective of the study was to develop a proposal for a pedagogical intervention in Music Teaching, using a bilingual approach, with deaf and hearing students, in the context of regular school classes. The research is based on the theoretical framework presented in Penna (2010), Brito (2001) and Fonterrada (2008), with reference to music education, and Haguiara-Cervellini (2003), Finck (2009) and Louro (2006), with reference to inclusion in teaching music. To achieve this objective, we developed a proposal for intervention based on the methodological dictates of intervention research, presented in studies by Jobim and Souza (2011) in light of the theoretical concepts posited by Mikhail Bakhtin, which assert that knowledge is produced through interaction between subjects, dialogically and through alterity. This methodology was carried out in pedagogical workshops, conceived as spaces for the construction of knowledge, mobilizing participants to engage in ludic activities of musical experimentation. Content covered in these workshops focused on Pulse and Rhythm – basic elements in music education – demonstrating that awareness about and sensitivity to these elements is not limited to the auditory sensory perception of the student, once the entire body is used as an agent of acquisition and expression. Thus, we began the trajectory of our research from the starting point of the identification and perception of „Pulse‟, using one‟s own body and the body of classmates, representing it through physical expressions and movement. Subsequently, this Pulse was extended from the body to a percussion instrument, and was then represented graphically as lines of rhythm, constituting a process of reading and writing; ultimately the intervention culminated in the class presentation with the musical group De Pau e Lata (Stick and Can). In our analysis, faced with the challenges and possibilities presented in our study, findings showed satisfactory results with regard to the participation of all of the students: completing the activities proposed in the class, asking questions when they did not understand, positioning themselves when they thought it necessary, expressing opinions about the work completed, evaluating the workshops given, interacting, helping in the activities, constructing knowledge collaterally, experimenting and experiencing musical elements through the body in activities that applied to both groups (deaf and hearing) in the one class. These indications elucidate the viability of teaching music to deaf and hearing students, using a bilingual approach, and based on experiences with the body and communicative and cultural specificities involved, confirming, as well, the role of Sign Language as a mediator in the teaching/learning process.

Núcleos de acessibilidade e o atendimento a alunos com necessidades educacionais especiais nas universidades federais do nordeste brasileiro

In the current context of policies for inclusiveness in the Brazilian higher education, the accessibility centers are responsible for the organization of actions toward the fulfillment of the legal requirements regarding accessibility and the elimination of barriers that interfere with the participation and learning of persons with special learning needs (SLN), providing conditions for the full inclusion of these students in the activities of learning, research and community outreach in this learning level. This research had the goal to analyse the work developed by the accessibility centers in the federal universities in the northeastern region of Brazil towards the care of students with SLN. It is a descriptive work, with quantitative and qualitative approaches. Twelve federal universities participated through their accessibility center’s coordinators. The data - gathered by means of an electronic survey filled out in 2014 - was organized and analyzed through descriptive statistics and content analysis; their discussion was made around four topics: organization of accessibility centers for the care of students with SLN, kinds and numbers of students with SLN cared for, actions developed, and suggestions for the improvement of the accessibility centers. It was found that in the sphere of the researched universities, the accessibility centers have been taking actions involving many parts of the academic community towards the improvement of the conditions and permanence of students with SLN. However, in some institutional realities, these action need to be expanded and/or consolidated. The coordinators suggest further actions towards the betterment of these centers, regarding expansion of financial and human resources, professional qualification, awareness of the academic community, institutionalization and the formation of a collaborative network among the accessibility centers. Thus, although there are still challenges to overcome, the presence of the accessibility centers is shown to advance the realization of policies for the inclusion of students with SLN in the post-secondary education, towards the democratization of learning starting from the universal right to education.

Formulação de pasta de cimento flexível utilizando planejamento experimental

Steam injection is an oil recovery method accomplished by introducing steam directly into the oil well to the reservoir. The steam causes dilation of the casing, which, after reduction in temperature, tends to return to the initial dimensions: causing the formation of cracks in the cement and loss of hydraulic isolation.. In this context, the type of the SBR latex is used to improve the flexibility of the cement matrix by reducing the amount of fatigue failure. To prevent these failures, the mechanical resistance parameters should be carefully adjusted to well conditions. This work aims to study the mechanical behavior of cement slurry systems additivated with SBR latex for cementing oil wells subject to steam injection. Through the central composite factorial design was studied the behavior of the compressive strength by varying the density of the paste between 1.75 g /cm³ (14.6 lb/ Gal) and 1.89 g/cm³ (15,8lb / Gal), curing time between 4 days and 28 days and concentration of SBR Latex between 0 L / m³ and 534.722 L / m³ (0 gpc and 4 gpc). The results showed that increasing the concentration of SBR latex, within the given ranges, there was a decreased compression resistance and elastic modulus by increasing the elastic deformability of the slurry. From the results it can determine best slurries formulation conditions in oil well cementing operations subject to steam injection.

O que tenho a ver com isso? aula-vivência sobre violência contra crianças e adolescentes

A violência constitui hoje a principal causa de morte em crianças de 5 a 19 anos, o que tem imposto aos profissionais de saúde um olhar mais atento a estas questões, bem como uma formação que busque compreender este fenômeno sobre os vários prismas que a circunscreve. O objetivo deste artigo é relatar a experiência vivenciada com alunos do curso de Graduação em Enfermagem da Universidade Federal do Rio Grande do Norte numa aula-vivência sobre esta temática. A aula foi baseada numa prática pedagógica de ação reflexiva. Desenvolveu-se a partir da integração dos conteúdos teóricos e práticos, articulando-os com temas sociais, políticos e econômicos. A aula foi dividida em três momentos: um momento de sensibilização; um segundo momento onde foi apresentado e discutido o arcabouço teórico, científico e legal que envolve o tema; e um terceiro, que visou estimular uma reflexão sobre a realidade vivenciada nos serviços de saúde por profissionais que atuam diante de situações de violência. Nos três momentos da aula pudemos proporcionar ao aluno a inquietação e a reflexão necessárias para pensarmos sobre a violência em toda a sua complexidade, pluricausalidade e com toda a carga de preconceito em que esta se encontra envolvida
