The composition of ichthyofauna discarded by trawling shrimping, their reproductive status and feeding ecology were studied on the beaches of Basin Rio Grande do Norte, Brazil. Fish were collected monthly in the year of 2012. During biometrics, portions of the digestive tract and of gonads were removed, fixed in formalin 10% and Bouin, respectively, for be submitted to histological processing by the techniques of hematoxylin-eosin. Stomach content analyzes were performed using the methods of Frequency of Occurrence and Volumetric and was calculated the repletion index. Throughout the study period were recorded a total of 49 species. The fish assemblages differed between sections monitoring, with the highest abundance, biomass and indices of richness and diversity in sections B, D and C. Already the excerpt A, showed higher values for dominance and equitability. In the cluster analysis according to the faunal similarity was observed the formation of three groups: group I formed by excerpts B and D, group II by excerpt C and group III formed by excerpt A. The assessment of reproductive stage revealed that the fish assemblages discarded by trawling are composed mainly of juveniles. Regarding the feeding ecology, the species Larimus breviceps, Menticirrhus littoralis and Pomadasys corvinaeformis characterized as carnivorous with tendency to carcinofagia. Already Conodon nobilis characterized as carnivorous with tendency to piscivory, but all proved generalist-opportunistic with increase of feeding activity during drought. The dendrogram of grouping of the species developed based on the food items used shows the formation of four groups: Group I consists of species that feed mainly of "gastropod" and "sediment"; group II of "teleost fish"; the group III of "crustacea" and group IV of "echinodermata" and "bivalve". The anatomical and histological characteristics of the digestive tract were consistent with the dietary habits of the analyzed species. In this context, the Costa Branca of Rio Grande do Norte can be considered a feeding site and recruitment for juveniles, which, opportunistically, utilize resources associated with the background

Objetivou-se neste trabalho a obtenção de padrões de infestação de plantas daninhas na cultura de cana-de-açúcar com histórico de colheita mecanizada sem queima prévia da palha. Foram realizadas amostragens em 28 talhões na região de Ribeirão Preto, SP; em cada talhão foram demarcadas unidades de avaliação e coleta, na proporção de duas por hectare, que consistiram de áreas (quatro linhas de 4 metros de comprimento) mantidas sem controle de plantas daninhas e onde foram realizadas as amostragens de plantas emergidas. As amostragens foram realizadas aos 120 dias após o corte, com quadrados vazados (0,5 x 0,5 m) lançados aleatoriamente duas vezes em cada uma das unidades de avaliação e coleta. Com os dados obtidos, calculou-se a importância relativa e o índice de agregação das espécies ou grupo de espécies. Esses índices foram usados no processamento da análise de agrupamento hierárquica, utilizando como medida de semelhança a distância euclidiana e como estratégia de agrupamento o método UPGMA (Unweighted Pair-Group Method using arithmetic Averages). Foi possível distinguir quatro grupos em função da importância relativa e cinco grupos de talhões em função do índice de agregação; dentro de alguns grupos houve formação de subgrupos.

A alface-d'água (Pistia stratiotes) é uma das principais entre as macrófitas aquáticas que causam problemas em corpos hídricos no Brasil e são consideradas como plantas daninhas. O presente trabalho foi realizado com os objetivos de conhecer melhor a variabilidade genética dessa macrófita e relacionar essa variabilidade com a resposta à aplicação do herbicida glyphosate. Para isso, foram coletados indivíduos em 12 corpos hídricos em diferentes cidades do território nacional (Americana, Cambaratiba, Curitiba, Itapura, Jaboticabal, Lagoa Santa, Piraí, Rio Grande, Rubinéia, Salto Grande, Santa Gertrudes e Três Lagoas). Os acessos foram caracterizados pelo uso de marcadores RAPD (DNA Polimórfico Amplificado ao Acaso), que permitiram, com o auxílio de iniciadores aleatórios, a caracterização dos locos polimórficos identificados por uma matriz de ausência e presença de bandas. Utilizando essa matriz, a análise de agrupamento permitiu nítida classificação dos acessos em três grupos com diferenças genéticas entre eles. Um ensaio de controle químico, com plantas mantidas em vasos plásticos (5 L) e pulverizadas com o herbicida glyphosate nas concentrações de 0,0, 0,6, 1,2, 1,8 e 2,4 kg ha-1, identificou, utilizando avaliações aos 7, 14 e 21 dias após aplicação, que as duas maiores doses promoveram melhor efeito herbicida. Foi verificado também que os acessos de Curitiba e Cambaratiba apresentaram menor suscetibilidade ao herbicida glyphosate. Não houve correspondência entre a estrutura de grupos dos acessos pela análise multivariada de agrupamento com a técnica RAPD e a suscetibilidade da alface-d'água ao glyphosate.

O objetivo deste estudo foi avaliar a possibilidade de agrupar talhões de cana-de-açúcar colhida mecanicamente e sem queima prévia da palha na região de Ribeirão Preto-SP, de acordo com o potencial de infestação de plantas daninhas, por meio de análise de agrupamento por método hierárquico e outras técnicas de análise multivariada, utilizando como variável o índice de infestação relativa atribuído por avaliações visuais, em duas etapas. A primeira contemplou 20 talhões de cana-planta com ciclo de 18 meses; essas áreas foram utilizadas para comparação de dois métodos de estimativa da composição específica da flora daninha: análise fitossociológica e por meio da porcentagem visual de cobertura geral (CG) e específica (CE). A segunda etapa consistiu no levantamento da composição específica da comunidade de plantas daninhas em 189 talhões, em áreas de cana-soca colhidas durante a safra de 2008, incluindo nesses talhões apenas CG e CE. Com as informações sobre os levantamentos da comunidade infestante foi construído um banco de dados, posteriormente submetido a análises exploratórias por técnicas de estatística multivariada. Para as principais espécies dentro dos talhões, que foram DIGNU, ARACH, IPOHF, MRRCI e IPOQU, seguidas de CYPRO, ELEIN e EPHHS, foram verificados 75% de coincidências de resultados entre os dois métodos de avaliação. Também notou-se que as avaliações visuais de porcentagem de cobertura das espécies podem substituir, para fins de praticidade, agilidade e aplicabilidade, as avaliações fitossociológicas, uma vez que proporcionaram boa capacidade de detecção das principais plantas daninhas dentro de cada talhão. As técnicas de estatística multivariada demonstraram que os talhões podem ser agrupados de acordo com semelhanças na intensidade da infestação e na composição específica.

The thesis entitled The administrative reform and social political management in Mossoró: the institutional and social staff's falacy. Comprehends a moment of apprehensiveness and analysis in the reestrcturing process of the city, whose process will show the formation of strategies and deployment of its relation with the social political affectiveness. It represents a single moment in the approach of such a kind of experience in the city. The analysis starts from the third mandate of the Mayor Rosalba Ciarlini Rosado, during the quadriennium 2001/2004, for being the time in which the public management got materialized, such as in the operational way of the social politics. For that, we delimitate this study in two distinct moments: the first one refers to the reform elaboration from the creation of the additional law nº 001/2000 GP/PMM: the second one refers to a practical reform from the social and institutional staff's speech. Within that scenary it was seen that the approaching, though partially, the State Reform and, consequently, the master plan of the state apparatus, which were made of theoretical matrices of such a project locally. However, that is a complex experience, that required the use of field and documental research for the proposed investigation and at the same time, prove the guiding hypothesis of it, what means a grouping of areas like: education, healthy, and social development in only one department City Citizenship Department that is able to materialize a new intitutional arrangement, according to the management principles in the public administration at the govern local level, configuring a reform and not just an institutional adequacy. In that context, it got necessary to apprehending the institutional and social actors' falacy as a way to prove or not the presented hypothesis. Among the first staff, we have the mayor's direct leaders and advisors' perception that express the politcal administrative aspects of the reform and, in the second, the perception of the political view of what has changed concerning the management of the social politics

This study want to know how Josué de Castro, the two terms of a congressman, participated in the Brazilian political-ideological debate of the 1950s. For this, search the 61 speeches in the plenary of the House of Representatives and its 14 projects, analyzing them as historical documents that describe an experience, which enables the central category amalgamated the subject and his time, which breaks up the possibilities of new social practices. Unity of action and reflection, the experience of Castro in the Brazilian parliament has got on the basis of a previous flow experiences in the political-institutional and scientific. Together with the personal history, the political intellectual scenario of his time was another variable considered in the first chapter of this work. In the second chapter did an analysis of 32 speeches and projects of the first term of Josué de Castro, grouping them by thematic affinities. The 43 for the second term were discussed in the third chapter, leaving the final considerations answer the research objectives: What are the main interlocutors? What are your political positions? What are the points of rupture and continuity in his political career? Josué de Castro spoke to the Brazilian state directly to the president, some ministers and to the SUDENE, the ONU appears indirectly through the reports of his participations. His political position was a national-developmentalist who embraced the cause of self-determination of the countries, anti-imperialism, agrarian reform and regional planning, strongly inspired by Celso Furtado and San Tiago Dantas. Castro often has blended a liberal and Marxist terminology, relying on different ideologies to do support his fight against hunger

In this paper artificial neural network (ANN) based on supervised and unsupervised algorithms were investigated for use in the study of rheological parameters of solid pharmaceutical excipients, in order to develop computational tools for manufacturing solid dosage forms. Among four supervised neural networks investigated, the best learning performance was achieved by a feedfoward multilayer perceptron whose architectures was composed by eight neurons in the input layer, sixteen neurons in the hidden layer and one neuron in the output layer. Learning and predictive performance relative to repose angle was poor while to Carr index and Hausner ratio (CI and HR, respectively) showed very good fitting capacity and learning, therefore HR and CI were considered suitable descriptors for the next stage of development of supervised ANNs. Clustering capacity was evaluated for five unsupervised strategies. Network based on purely unsupervised competitive strategies, classic "Winner-Take-All", "Frequency-Sensitive Competitive Learning" and "Rival-Penalize Competitive Learning" (WTA, FSCL and RPCL, respectively) were able to perform clustering from database, however this classification was very poor, showing severe classification errors by grouping data with conflicting properties into the same cluster or even the same neuron. On the other hand it could not be established what was the criteria adopted by the neural network for those clustering. Self-Organizing Maps (SOM) and Neural Gas (NG) networks showed better clustering capacity. Both have recognized the two major groupings of data corresponding to lactose (LAC) and cellulose (CEL). However, SOM showed some errors in classify data from minority excipients, magnesium stearate (EMG) , talc (TLC) and attapulgite (ATP). NG network in turn performed a very consistent classification of data and solve the misclassification of SOM, being the most appropriate network for classifying data of the study. The use of NG network in pharmaceutical technology was still unpublished. NG therefore has great potential for use in the development of software for use in automated classification systems of pharmaceutical powders and as a new tool for mining and clustering data in drug development

Os cães possuem cinco grupos sangüíneos bem estabelecidos, compostos por sete determinantes antigênicos eritrocitários, os quais são denominados de dog erythrocyte antigen (DEA). O grupo DEA 1 (subgrupos 1.1, 1.2 e 1.3) tem sido considerado o mais importante no que se refere às transfusões de sangue. Isto ocorre porque esse grupo possui um alto potencial para estimulação antigênica e, dessa forma, pode estimular a produção de anticorpos se um receptor DEA 1 negativo receber uma transfusão de sangue DEA 1 positivo, levando a uma reação transfusional hemolítica em uma segunda transfusão com hemácias do tipo DEA 1. A freqüência de aparecimento do grupo DEA 1 é bem conhecida em outros países, porém, até então, não havia informações disponíveis sobre o referido grupo no Brasil. No presente estudo, objetivou-se avaliar a prevalência do grupo sangüíneo DEA 1 (subgrupos 1.1 e 1.2) em cães criados no Brasil. Para tanto, 150 cães de raças, sexos e idades diferentes, triados junto ao Hospital Veterinário da FCAV/UNESP, Campus de Jaboticabal, foram submetidos a tipagem sangüínea para o grupo DEA 1 (subgrupos 1.1 e 1.2) canino, utilizando-se reagentes adquiridos comercialmente junto ao Laboratório de Imunoematologia e Sorologia da Universidade de Michigan (EUA). Os resultados obtidos neste ensaio revelaram que a prevalência geral para o grupo DEA 1 é de 91,3%, consideradas as condições e características da população estudada, compreendendo 51,3% de cães do tipo DEA 1.1, 40% de cães do tipo DEA 1.2, e os 8,7% restantes sendo negativos para o referido grupo. A partir das prevalências encontradas, calculou-se que a probabilidade de um cão DEA 1 negativo receber sangue DEA 1.1, em uma primeira transfusão feita ao acaso, é de aproximadamente 4,5%. Sendo assim, este índice reflete um risco potencial para a sensibilização de um receptor DEA 1 negativo, o que deflagraria a produção de anticorpos. Posteriormente, se este mesmo paciente recebesse uma segunda transfusão de sangue, feita ao acaso, a probabilidade de receber hemácias do tipo DEA 1.1 seria de aproximadamente 2,3%, o que representaria o risco potencial de ocorrência de uma reação transfusional hemolítica aguda. Por outro lado, a probabilidade de este cão receber sangue do tipo DEA 1.2 seria cerca de 1,8%, o que levaria a uma reação transfusional menos grave, porém potencialmente prejudicial. No presente estudo, observou-se que o risco potencial para uma reação transfusional é mínimo, quando se trata de um cão mestiço.

This investigation had the teacher as object of study, whose objective was to know and analyze the teacher‟s Social Representations (SR) shared by undergraduates, as from images of this professional (teachers´ photos of several levels and school systems). It was searched out the process of depreciation or estimation, in which the teaching profession has been passing, trying to catch, specifically, possible existing correlations among such SR and the reflections in the attitudes developed by these students about their own development and professional practice. The data collection was carried out at the Federal University of Piauí Teresina with 165 undergraduates (15 from each course). It was applied a semi-structured interview, mediated by iconographic grouping (SALES, 2000, 2007), outlining a methodological widening of the studies fulfilled by (ROAZZI, 1995). It was used the function Factor Analysis, available in the SPSS (Statistical Package for the Social Sciences) for the analysis of the quantitative data, and it was proceeded a content analysis through the categorical analysis technique (BARDIN, 1977) for the analytical procedures of the qualitative data. It was resorted to the SR theory (MOSCOVICI, 1978) for the data interpretation and the Theory of Signs (PEIRCE. 1995) in the understanding of the decodification processes of signs that were present in the photos worked. It became evident that the undergraduates perceived the teaching profession inserted in a hierarchical scale of values (positive/negative), directly related to the school system and the teaching level, in which the teacher works. Most undergraduates share teacher‟s SR of negative content, consolidating the hegemonic SR about the teacher‟s social depreciation, although some of them imagine themselves, in the future, inserted among the teachers more appraised, showing that the SR orientate the positive and negative attitudes about the teacher. The presence of SR that mobilize the interviewers‟ attitudes in opposite senses related to the teacher, offer evidence of the necessity of future studies that can use a methodology more focused to understand other motivation factors that the undergraduates give evidence of having to the course they have chosen, besides the ones inferred by the SR caught in this investigation, as well as to establish a correlation between the teacher‟s SR (positive and negative) and the social economic level of the interviewers that share them. Such data revealed itself necessary since the literature signalizes for a relation between the course chosen and the applicant‟s social-economic level, and that the applicants‟ objective conditions to the licenciature courses are related to the subjective hopes that their group supplies

A divergência genética de 16 cultivares de arroz quanto à resistência ao percevejo-do-colmo-do-arroz, Tibraca limbativentris Stål, foi avaliada por meio de técnicas de análise multivariada. O experimento foi conduzido em casa de vegetação, em delineamento experimental de blocos ao acaso, com oito repetições. Na avaliação foram considerados oito caracteres de resistência ao ataque do inseto. A divergência genética foi avaliada por procedimentos multivariados: distância generalizada de Mahalanobis (D²), método de agrupamento de otimização de Tocher e técnica de variáveis canônicas. As cultivares mais dissimilares foram Bico Ganga e Marabá Branco, enquanto Agulha e Branco Tardão foram as mais similares. Foram formados cinco grupos pelo método de otimização de Tocher. As três primeiras variáveis canônicas explicaram 88,5% da variabilidade total disponível. Conclui-se que as técnicas de análise multivariada são eficientes para a análise da divergência genética entre as cultivares de arroz, com destaque para Marabá Branco e Bico Ganga, consideradas as mais promissoras a serem utilizadas em futuros cruzamentos para melhoramento visando resistência ao percevejo-do-colmo-do-arroz.

This study investigates the contributions of reading literature for the development of creative thinking in childhood. Its relevance consists in exploring practices that contemplate the creative thinking development in apprentices at school space and understanding the literature like a significant way to promote the creative thinking. The study is connected to the qualitaty strand. The exploratory observation and the intervention were adopted as research techniques. The field diary and the audio and video recording of the reading sections were adopted as methodological instruments. The research was conducted in the application s college from the Federal University of Rio Grande do Norte, in a 1th grade class, with 18 students between 6 and 7 years old. During the intervention, 8 readind class happened, with varied strategies and literary genres. The reading sessions were conducted through the principles of scaffolding, defended by Graves and Graves (1995). The corpus is made of speaks episodes, whose encoding semantics allowed the grouping into two central categories: divergent thinking and coauthoring of literary reader. It was taken as a theoretical framework the studies of Amarilha (2011; 2006; 2001; 1991; 1993; 1994), Alencar (2001), Coelho (2000; 1997), Culler (1999), De Masi (2005), Gallo (2000), Guilford (1977), Iser (1996), Jouve (2002), Kneller (1978), Martínez (1997), Smith (2003), Stierle (1979), Vigotski (2009; 1998), Wechsler; Nakano (2003; 2002). The analysis points to the formation of creative individuals in the classroom, through the reading of literature. Reposition the literary education front of the new social demands. Resizes the function of school in children s development, considering the children s skill in exploring, testing hypotheses and making use of their creative thinking, in climate of freedom mental. It signals, in this way, the teacher like a mediator, promoting a favorable to the development of creative thinking environment, a stimulating atmosphere, which enhances the expression of creative thinking in community

Avaliou-se a divergência genética entre quinze linhagens (Hav 13, Hav 14, Hav 21, Hav 22, Hav 25, Hav 38, Hav 40, Hav 41, Hav 49, Hav 53, Hav 56, Hav 64, Hav 65, Hav 67 e Hav 68) e cinco cultivares (Macarrão Favorito AG480, Macarrão Preferido AG482, Manteiga Maravilha AG481, Teresópolis AG484 e Macarrão Bragança) de feijão-vagem de crescimento indeterminado, utilizando-se vinte características agronômicas. O ensaio foi conduzido na AGENCIARURAL - EE de Anápolis, no período de 30/04 a 10/08/1998. Os dados foram submetidos às análises de variância e multivariada (distância D² de Mahalanobis e o método de agrupamento de Tocher). Houve diferenças significativas entre os genótipos para as características consideradas. Os genótipos Hav 13, Hav 49, Hav 56, Hav 64, Hav 68, Favorito AG480 e Teresópolis AG484 destacaram-se com relação ao conjunto de características favoráveis a produtores e consumidores. Houve maior freqüência de pares com maiores distâncias, quando um dos componentes era a cultivar Teresópolis AG484 ou Hav 49, e de pares com menores distâncias quando seus componentes tiveram como ancestral comum a linhagem Hab 229. Os genótipos distribuíram-se em quatro grupos, sendo um constituído exclusivamente pela linhagem Hav 49, outro englobando as cultivares Manteiga Maravilha AG481 e Teresópolis AG484. A linhagem Hav 41 e as cultivares Macarrão Favorito AG480 e Macarrão Preferido AG482 um terceiro grupo, e os demais genótipos um único grupo. As características que mais contribuíram para a divergência entre os genótipos foram o número de dias para o início de floração e o comprimento das vagens, com 58,11% do total, seguidas da porcentagem de palha na vagem seca, da largura das vagens, das alturas das plantas nas duas épocas avaliadas, do peso médio de vagem e do número de vagens por planta que, em conjunto, contribuíram com 85,73% do total.

The environment of Intensive Care Unit (ICU) is commonly referred to as a place where caring is inextricably linked to high technology. The care in ICU often changes the patient into a taxpayer being left apart from its complexity and sometimes seen through a reductionist perspective. Thus, studies circa the care process are needed oriented from a historical ransom, raising the prospect of a more centralized human care. Hence, this study aimed to analyze the care process in a nursing intensive care unit from the perspective of the professional, family and patients. The study is characterized from a qualitative, descriptive and exploratory methodological approach. The actors were participating nursing professionals, patients and family members of an intensive care unit of Mossoró / RN. Data were collected in the period of May-June 2011, through interviews and observation of activities performed by nursing professionals, and their records in the chart. Data analysis was divided into topics and subtopics representing the phases and shapes that formed the collection. The analysis and discussion of the interviews were based on Bardin's proposal, when we created categories from a process of sorting and grouping criteria adequately defined. The observation of nursing records intended to observe the emphasis which is described in those notes as well as their consistency with practice of FCN and resolution 358/2009. The analysis showed that the nursing staff also performs work focused on mechanized activities and technical-bureaucratic institution that seem to override the needs of patients. In an overview, the care provided by professionals occurs either fragmented or insipient, however there is a service that involves other aspects beyond technical-curative practice, considering that major attention is given to the family and patient, focused on the concern of Nursing guiding their actions in not only the performance of procedures. However, the process of humanizing not always ends with an engagement between professional and patient, which mischaracterizes the true meaning of human care. The records also showed a tendency to focus on caring in a positivist line, where, in most cases, the factors of the disease and the obligation to meet the productivity have overshadowed other relevant aspects to a holistic understanding of caring. Regarding FCN Resolution No. 358/2009, which guides a systematization of nursing care, it is confirmed a technical view, a fragmented and superficial view of the patient, as well as a weakness of care, caused by ignorance and unpreparedness of the entire team. The perspective of caring demonstrates a reality with dialectic between what is proposed in a humane nursing and what happens in this performance space. Besides, it was shown a daily full of important considerations that arise in professional practice, in their views and also those people who were participants in the process
