The research aims to analyze Professor Education in Natal, Rio Grande do Norte-Brazil in the period of 1908 to 1971. The work falls under the theme History of Scholar Institutions as well as Professor Education. The research investigates the evolution of the so called Normal School, a school that aimed professor education. It was based on assumptions by works of Chartier (1990), Chervel (1990), Elias (1994), Nóvoa (1987), Schriewer (2000), amongst others. The research dealt with a great array of documents in different institutions such as Minutes, Public Instruction Management Reports, Laws, newspaper articles (from the newspaper A Capital, A Ordem e A República), magazines such as Pedagogium (1921-1940); all of which present in the Geographical and Historical Institute of Rio Grande do Norte in Brazil. In the State´s public archive it was possible to find a book called Livro de Honra (1914-1919) as well as class diaries and books that contained details related to Scholar group Inscriptions. In the Atheneu Memorial the Atheneu Congregation of Normal School (1897) document was analyzed. In the Kennedy Superior Institute the researcher analyzed the Professor Nominal Graduation Registry Book. The work proposes a comparative study regarding the genesis present in the Lisbon Primary Normal School and the ones situated in Natal. The analysis dealt with institutional meanings attributed by educators. Documents from The Portuguese National Library as well as the Lisbon Superior Education School were analyzed. In this in environment, it was possible to analyze documents such as Minutes, Books, Manuals, Internal Regiments related to Pedagogy. The study allowed acknowledging that these Normal Schools emerged from the same historical substrate and present consonance between the two countries regarding once both were associated with politicians, professors, doctors, hygienists and professionals evolved with education. It was also possible to acknowledge that there is a presence of a pedagogical discourse attached to the primary school universe and professor education. The Natal Normal School was present in different contexts and was consolidated as an institution that was responsible for the education and preparation of primary school teachers. The school was considered a locus where it was possible to produce and work with specific knowledge in a peculiar fashion. This knowledge provided the necessary support for professor education and was in accordance with the world´s professional pedagogical movement as well as ideas, discussions and reflections. This school was considered a space for pedagogical activities, professional affirmation allowing action reflection enabling professor representation as knowledge producers legitimating professor instruction

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

This thesis is the result of an extensive research on print media discourse on the inclusion of disabled people in society. Articles published in the newspapers Diário de Natal/O Poti and Tribuna do Norte from 1992 to 2002 have been analyzed. Beginning with the very same questions that moved Moscovici (1978) in his classic study La Psychalyse son image et son public , according to which the media play a predominant role in the formation and propagation of social representations as well as in the construction of human behaviors, we have chosen this mass media as our investigation field. Understanding the importance of the communication theory, we intend to associate it to the social representation theory, since communication, as an aspiration, relates to the fundamentals of all humanity (WOLTON, 2004, p. 56). Moreover, means of communication represent an important space for symbolic production and representational process, allowing the analysis of the circulating discourses on social inclusion and disability. Based on these questions, we have determined social representations present in print media on the subject to be our study object. This objective was elected due to the fact that the thematic of disability and inclusion is scarcely and sporadically found in journalistic speech. The research questions have been: which is the representation of disabled people s condition in print media? What changes have occurred during the analyzed period and which was the role played by print media in this process? The research corpus was composed of newspaper articles about various aspects concerning disability and of free word association by reporters. We have analysed: 1) graphical language promoted by the picture of the substances propagated in the period from 1992 a 2002; 2) free word association experiments carried out with reporters of both newspapers; and 3) texts published from 1996 to 1997 using the high-tech program ALCESTE (Contextual Lexical Analysis of a Set of Segments of Texts). The results revealed that the print media in Natal/RN refer to the topic in a discontinuous way, and depend on specific events to highlight disabled people s fight for their rights. Social inclusion is still a great challenge for these people in all levels. We believe that this incapacity to overcome all kinds of obstacles is established in a dialectic relation between society and the media: society remains silent (the manifestation of interest for the cause only attracts some people s or groups attention) and the media, which selects which information is to be broadcasted, gives no evidence to the issue. This representation may be noticed in the infrequency in which articles about the subject are published, as well as in the emphasis to sports, a more important issue for the media. An implication of this study is that a new perspective is opened for analysis and reflection: the Paralympics games as both an inclusive and a segregating social phenomenon. It would be beautiful to have all of us together!

O presente trabalho teve como objetivo verificar a forma de penetração do fungo Metarhizium anisopliae [METSCH. (SOROKIN, 1883)] em carrapatos da espécie Rhipicephalus sanguineus (LATREILLE, 1806), assim como as lesões infringidas nos tecidos internos do ácaro. A forma de aderência e penetração do fungo foi estudada através da microscopia eletrônica de varredura e a ação do fungo nos tecidos internos avaliada em secções histológicas convencionais. Para observação destes eventos, realizaram-se infecções experimentais em 11 grupos de fêmeas ingurgitadas do carrapato R. sanguineus contendo 12 fêmeas ingurgitadas cada. Para tal, as fêmeas ingurgitadas foram banhadas durante 3 minutos, sob agitação manual, em suspensão com concentração 108 conídios/mL. No caso dos grupos controle o banho foi realizado apenas no veículo da suspensão. Os carrapatos foram processados para histopatologia e microscopia eletrônica em diversos tempos após a infecção, a saber: 1 e 18h, e um, dois, três, quatro, cinco, seis, sete, nove e onze dias. Observou-se que a maior parte dos conídios germinou em até 18h após a inoculação e que o fungo penetrou no ácaro através do tegumento 48h após a infecção. Após a penetração, o fungo invadiu o corpo do hospedeiro promovendo uma colonização difusa, sem preferência aparente por tecidos específicos. Dentre as lesões nos tecidos internos do ácaro, ressalta-se o rompimento da parede intestinal e vazamento do conteúdo para a hemocele. A morte do hospedeiro ocorreu entre 96 e 120h pós-infecção, e a esporulação do patógeno sobre o cadáver do ácaro iniciou-se em torno de 120 a 144h pós-infecção. Espera-se, com este trabalho, contribuir para o desenvolvimento e viabilização de técnicas de controle biológico dos carrapatos por fungos como alternativa ao uso de acaricidas.

Examinaram-se a adesão, a germinação, a penetração e a colonização de larvas e ninfas de Rhipicephalus sanguineus por Metarhizium anisopliae, assim como as lesões infringidas pelo fungo nas respectivas fases do ciclo de vida do ácaro. Realizaram-se infecções experimentais em 11 grupos contendo 250 larvas e 11 grupos contendo 75 ninfas de R. sanguineus, por meio de banho, durante três minutos sob agitação manual, em suspensão contendo 10(8) conídios/ml do fungo. Nos grupos-controles, o banho foi realizado usando o veículo da suspensão. Larvas e ninfas foram processadas para um estudo histopatológico e de microscopia eletrônica de varredura nos seguintes tempos após a infecção: uma e 18 horas, e um, dois, três, quatro, cinco, seis, sete, nove e 11 dias. A germinação dos conídios ocorreu em até 18 horas pós-inoculação, e o fungo penetrou nas larvas e ninfas através do tegumento, dois e três dias após a infecção, respectivamente. Após penetração, o fungo invadiu o corpo das larvas e ninfas, promovendo uma colonização difusa, sem preferência aparente por tecidos específicos. Lesões significativas não foram observadas. A morte das larvas e ninfas ocorreu no terceiro e quarto dias pós-infecção, e a esporulação do patógeno sobre o cadáver foi iniciada no sexto dia pós-infecção.

O presente trabalho foi conduzido com o objetivo de avaliar as características morfológicas e físicas da planta e do fruto de jabuticabeiras, pertencentes à coleção da FCAV-UNESP, Câmpus de Jaboticabal-SP. A coleção conta com 160 plantas, das quais 40, que apresentavam frutificação no momento da seleção, foram agrupadas, preliminarmente, segundo características semelhantes, em quatro grupos denominados JAB 01, JAB 02, JAB 03 e JAB 04. Mediram-se nestes grupos a altura da planta, diâmetro do tronco a 20 cm do solo, diâmetro de copa, comprimento do entrenó e largura da folha. Os frutos, foram avaliados quanto a comprimento, largura, massa fresca da casca, da semente, da polpa e total, bem como o número de sementes por fruto. O delineamento utilizado foi o inteiramente casualisado, com 4 tratamentos, quatro grupos de plantas e 5 repetições, com 2 plantas por repetição. Os dados foram submetidos à análise de variância pelo teste (F) e as médias comparadas pelo teste de Tukey. Observou-se grande variabilidade nos grupos estudados. O JAB-04 revelou-se como o mais promissor para utilização em programas de melhoramento, pela precocidade de produção, baixo porte e maior rendimento em polpa, apesar de os frutos apresentarem menor tamanho em relação aos dos demais grupos.

Cancer of the cervix (cervical cancer) is the second most prevalent cancer among Brazilian women. The high rates of cervical cancer in Brazil justify the implementation of effective strategies to control this, which include actions to promote health, primary prevention, early detection, screening, treatment and palliative care. Despite the existence of the National Programme for Control of the CCU there was no reduction in the incidence and mortality of this disease in Brazil. The Family Health Strategy (FHS) has the potential to facilitate such control and, in this context, one should consider that nurses play a central role. The study aimed to know the general intervention strategies used by nurses FHS of Natal / RN in CCU control, and how specific: analyzing the knowledge of these nurses on the CCU, the actions developed in the ESF for the control of CCU and identify the difficulties faced by them to perform it. This is a descriptive exploratory quantitative developed through a structured interview guide with 106 nurses who have experience in controlling the CCU in FHS teams of Natal / RN. Data analysis was performed using descriptive statistic s. The results pointed to actions taken in the FHS to control the CCU, collection of cervical cancer screening, health education activities, nursing consultation, referral of suspected cases for medical monitoring and active women with abnormal test result . The actions that were not mentioned by the nurses included: forming groups of prevention and health promotion; expand coverage of exams and office hours of consultations, establishment of alternatives to end the pent-up demand in the health units, participation in treatment or rehabilitation process users with the CCU; interventions for pain management, alliances and partnerships with schools, in dustry and the use of protocols. This study can be seen that the practice nurses partially shares to the CCU in Natal / RN. The participants of this study, when asked about the CCU, specifically for signs and symptoms of disease and risk factors in general showed important gaps. Difficulties such as lack of materials for collection of Pap smear; inadequate physical space in the Health Units; pent-up demand in the service, delay in arrival of the test results; obstacles in the actions of referral and counter-referral and cultural factors make the CCU control is compromised. It is believed in this research contributed to a reflection on the importance of the role of nurses in the development of the ESF control actions CCU, pointing out the factors that affect these. It is important to involve all nurses who comprise the ESF as knowledgeable of the risk factors, signs and symptoms, and existing tools for the early detection of cervical cancer in the pursuit of quality improvement actions to promote women`s health, contributing in planning future interventions that may reduce mortality from this disease in Natal / RN.

O objetivo deste estudo foi investigar, por meio de dados simulados, o efeito da heterogeneidade de variância residual entre grupos de contemporâneos (GC) sobre as avaliações genéticas de bovinos de corte, e comparar o uso de uma avaliação genética ponderada (R¹Isigmae²) em relação à avaliação que pressupõe homogeneidade de variância (R=Isigmae²). A característica estudada foi ganho de peso pós-desmame corrigido para 345 dias, sendo esta simulada com variância fenotípica de 300 kg² e herdabilidade igual a 0,4. A estrutura de um conjunto real de dados foi utilizada para fornecer os GC e os pais referentes às observações de cada animal. Cinco níveis de heterogeneidade de variância residual foram considerados de forma que os componentes de variância fossem, na média, iguais aos da situação de homogeneidade de variância. Na medida em que níveis mais acentuados de heterogeneidade de variância residual foram considerados, os animais foram selecionados dos GC com maior variabilidade, especialmente com pressão de seleção intensa. em relação à consistência de predição, os produtos e as vacas tiveram seus valores genéticos preditos mais afetados pela heterogeneidade de variância residual do que os touros. O fator de ponderação utilizado reduziu, mas não eliminou o efeito da heterogeneidade de variância. As avaliações genéticas ponderadas apresentaram resultados iguais ou superiores àqueles obtidos pelas avaliações que assumiram homogeneidade de variância. Mesmo quando não necessário, o uso de avaliações ponderadas produziu resultados não inferiores às avaliações que assumiram homogeneidade de variância.

Currently, one of the biggest challenges for the field of data mining is to perform cluster analysis on complex data. Several techniques have been proposed but, in general, they can only achieve good results within specific areas providing no consensus of what would be the best way to group this kind of data. In general, these techniques fail due to non-realistic assumptions about the true probability distribution of the data. Based on this, this thesis proposes a new measure based on Cross Information Potential that uses representative points of the dataset and statistics extracted directly from data to measure the interaction between groups. The proposed approach allows us to use all advantages of this information-theoretic descriptor and solves the limitations imposed on it by its own nature. From this, two cost functions and three algorithms have been proposed to perform cluster analysis. As the use of Information Theory captures the relationship between different patterns, regardless of assumptions about the nature of this relationship, the proposed approach was able to achieve a better performance than the main algorithms in literature. These results apply to the context of synthetic data designed to test the algorithms in specific situations and to real data extracted from problems of different fields

It proposes a established computational solution in the development of a software to construct species-specific primers, used to improve the diagnosis of virus of plant for PCR. Primers are indispensable to PCR reaction, besides providing the specificity of the diagnosis. Primer is a synthetic, short, single stranded piece of DNA, used as a starter in PCR technique. It flanks the sequence desired to amplify. Species-specific primers indicate the well known region of beginning and ending where the polymerase enzyme is going to amplify on a certain species, i.e. it is specific for only a species. Thus, the main objective of this work is to automatize the process of choice of primers, optimizing the specificity of chosen primers by the traditional method

The school is a privileged locus of pedagogical reflection and, therefore, can and must be the best place for the process of continuing graduation for teachers. This process can be very productive if executed with an interdisciplinary group, once interdisciplinarity enables sharing different disciplines and also different personal stories. This study aimed to build a continuing graduation opportunity with an interdisciplinary group of teachers to Natural Sciences area, in a private school in the city of Natal - RN. This opportunity was build using as a tool the elaboration of interdisciplinary class called dialog-lesson. The methodology was in accordance with the principles of the qualitative approach of search-action, and the methodological way consisted of three stages that sought to meet the specific objectives: the definition of multidisciplinarity and interdisciplinarity, which had teachers in the Natural Sciences area; present a proposal that emerged from group discussions, identifying some elements of the limits and possibilities of the activity developed by the group of teachers from the Natural Sciences area. The results showed a studies lack on the subject by teachers and induced the reading and studing the Education legal documents (LDB, PCNEM and OCNEM). The planning of lessons led to the need for meetings that established the process of continuing graduation in exercising at the school. The interdisciplinary practice enable many gains, for example, the cohesion of the teachers, the perception need to constantly update and use of teaching units for planning. But it was also possible to observe limits, such as the difficulty of working with large classes and the danger of the content become superficial. The experience has shown that continuing graduation at school is possible and can be beneficial the use of interdisciplinary groups for this purpose, because it allows the exchange of experiences and pratice reflection of teaching in the itself exercise of this teaching

This research part of the educational context of the Federal Rio Grande do Norte, through the resumption of legal frameworks that characterize it as an institution belonging to the Federal Network of Professional Education and Technology Brazilian, with a focus on continued education policies for the servers who work there specifically teachers, especially those who have their work in the Teaching of Natural Science and Mathematics. To do this the cut in an agreement between the IFRN and UFRN PPGECNM through the professional master's degree Teaching of Natural Sciences and Mathematics. This agreement as we have research collaborators 08 master teachers who graduated in the period 2004 to 2010, so we undertook a qualitative and quantitative research aimed to conduct the study in general terms of description and analysis of the impacts caused by the formation of masters IFRN in PPGECNM UFRN, taking into account the production of the same academic (dissertation), his performance in the context of the institution and the historical, social, economic and political aspects involved, and also meet the guidelines of the project at the Observatory in 2008 - MEC / CAPES / BSD-P. We used the theoretical options methodological elements of Comprehensive Interview and multireferentiality, our data collection instrument was the main interview, we also performed the analysis of dissertations by lecturers and teachers featured, from the specific descriptors used in catalogs USP / IFUSP (1992, 1996) and UNICAMP / FE / CEDOC (1998) and by other researchers. In analyzing and understanding the speech of the interviewees were able to identify the implications of teacher education in the school context, the motivation to seek the Master; how was the construction of the object of study of the educational product and its use in teaching practice and intervention, the question of the role of master teachers in the school environment to the post master taking into account changes in professional performance and influence in the working groups, how does the use of research and investigation in the classroom after training and between training and educational quality in the context of IFRN. In reading and analysis of the dissertations were able to identify the main focus and under-explored thematic focus as well as the theoretical methodological references. At the end of the research developed a product that could be used for technical analysis studies and assessment in quantitative terms the results achieved by the master teachers IFRN through his training in PPGECNM UFRN

This study presents the results of a survey conducted in the area of English for Specific Purposes (ESP) in order to identify (1) the learning needs of students in a course in Tourism, their desires and lacks, at a federal university, with respect to use of English; (2) the needs of the present situation of teachers and the coordinator of that course as to the language; (3) the needs of the target situation of professionals (graduates) and companies with respect to this language. This research is a case study (STAKE, 1998; YIN, 2009) and was used for data collection, instruments such as questionnaires, semi-structured interviews, and document on the Tourism Course. To this end, it was adopted the theoretical basis for the constructs of English for Specific Purposes (ESP) Inglês para Fins Específicos (IFE) in Brazil, also known as Inglês Instrumental, whose foundation is based on the work by Hutchinson and Waters (1987), Robinson (1991), Dudley-Evans and St. John (1998), Celani, Deyes, Holmes, Scott (2006), among others, since this work is devoted to a specific area, Tourism. Results show that students opined the ability to prioritize reading and speaking into the classroom. Professionals reported that the latter is an indispensable tool for entering the labor market, yet they feel unprepared and need to attend English language courses in private language schools. The testimony of company executives also point to this deficiency. Finally, the present situation of teachers reveals that, while advocating the use of English in the classroom, this is not because students prefer their mother tongue. There is also an evident lack of needs analysis. Eventually, the coordinator said that there is some uncertainty as to the methodology, content and language skills worked, and the lack of interaction among teachers of English. It was concluded, therefore, it is important to conduct a needs analysis so that one can redesign a course that meets the different contextual needs: students, teachers, coordination, represented by the institutional needs, and the labor market

The objective was measured by surface electromyography (EMGs), the activity of inspiratory muscles during incremental test in subjects with hemiparesis and show its correlation with the Functional Independence Measure (FIM). Were included in the study 32 individuals hemiparetics and 14 healthy as control group. We performed an evaluation of lung function and anthropometric data. The EMGs were performed during the incremental test with Threshold ® (15, 30, 45 and 60% of MIP) and during maximal inspiratory pressure (MIP). The electromyographic findings were calculated by the signal amplitude (RMS). All data were initially analyzed by Kolmogorov-Smirnov, the anthropometric characteristics of both groups were tested with the Levene and then intra-subject analysis (hemiparetic hemithorax and healthy hemithorax) and inter-group analysis (experimental group and control group) by paired and non-paired Student t tests and Pearson correlation. In intra-subject comparison was observed less activation (p <0.01) of the sternocleidomastoid muscle, scalene and diaphragm paretic side in both sexes - for the Threshold ® incremental test (15, 30, 45 and 60% of the MIP) and during maximal inspiratory pressure (MIP). In inter-group comparison, there was reduced activity in the diaphragm and the scalene, in hemiparetics males and females, respectivelly, during the same test. Our results demonstrate the existence of reduced electromyographic activity of inspiratory muscles in hemiparetics, including changes between different genders and suggests the need of further studies to assess the effects of specific training of inspiratory muscles.

Cytogenetic studies have been revealing a great diversity not detected, until then, in several families of fishes. Many of these groups, especially those that exhibit great diversity, like Perciformes and Siluriformes, possess species with difficult morphologic characterization, called cryptic species, commonly detected through karyotypic analyses, which reveals outstanding interespecific variations with relationship to the number and its chromosomal structures. Thus, the present work intends to contribute for the cytogenetic knowledge of marine and brackish fish species, because they peculiar life habits and by lack of cytogenetic data of your genetic aspects. Therefore, cytogenetic studies were developed in a species of Apogonidae (Perciformes), two species of sea catfishes of the family Ariidae (Siluriformes) and brackish fish Paurachenipterus galeatus (Siluriformes, Auchenipteridae), through C banding, Ag-NOR, use of base-specific flourochromes (DAPI and CMA3), as well as FISH (Fluorescent in situ hybridization) using ribosomal DNA probes 5S and 18S. The present results contribute to a better understanding of the processes of differentiation patterns and chromosome evolution in these groups. The use of other approaches (the morphology and molecular tools) will allow a larger understanding of the genetic and biological diversity of the Brazilian ichthyofauna.
