O papel de Rhizoctonia spp. binucleadas na indução de resistência a mela da soja

The role of non-pathogenic binucleate Rhizoctonia spp. (BNR) on the biocontrol of diseases caused by R. solani on many crops has been reported in the literature. However, in Brazil, there is no information about the potential of BNR as biocontrol agents against Rhizoctonia diseases on soybean. on this research we tested the hypothesis that BNR can induce resistance on soybean against the foliar blight caused by R. solani anastomosis group (AG) 1 IA. Thus, the objective of this research was to evaluate BNR isolates isolated from peanuts, snapbeans and soybean according to their ability for inducing resistance on soybean against the foliar blight disease, under greenhouse conditions. This research evidenced the role of BNR inducing resistance on soybeans against the foliar blight. However, both the occurrence and effectiveness of the phenomenon of induced resistance are dependent on the soybean cultivation season.

Efeito do período de envelhecimento acelerado no teste de condutividade elétrica e na qualidade fisiológica de sementes de feijão

The high quality of seed trading for producers is very important to obtain high productivity. The aim of this work was to evaluate the effects of different periods of artificial seed aging on contents of sugars, proteins, amino acids and ions, on imbibition solution of electrical conductivity test, as well as its relationships with standard germination and vigor in bean seeds at the Perola cultivar. The research was carried out at the Laboratory of Seed Analysis - Faculdade de Engenharia - Unesp - Campus de Ilha Solteira. The experimental design was in completely randomized blocks. The seeds were submitted to eight accelerated aging conditions (zero, 24, 48, 72, 96, 120, 144 and 168 hours). The seed germination, seed vigor and leakage contents in exudates of bulk conductivity were Influenced by the increase in the time of seed exposition to accelerated aging. After seventy-two hours of exposition to the aging, a considerable decline in seed germination and vigor was observed. There was also an increase of leakage contents, such as amino acids, sugars, potassium and phosphorus ions. The increase of leakage contents is inversely related to seeds germination and vigor.

Extensão universitária: concepções e ações na UFRN sob a temática direitos humanos e justiça no período 2008 a 2010

This paper concerns a study on the University Extension, by reference to the research extension activities under the theme human rights and justice, developed in the period 2008 to 2010 in UFRN. To do so, it tried to learn the concepts of extension in Brazil from the 1970s until the 2000s in contemporary times. This study considered the neoliberal social context of the University, dominated by educational policies focusing on the hegemony of liberal ideas about society, reflecting the great advances of capital on the organization of workers in the last decades and intensified in the 1990s. This research was guided by two great motivations: the opportunity to apprehend a way to enforce the commitment of public institutions of higher education to the disadvantaged sections of society and what role the university extension space plays as a socially committed public university. The general aim of this study is to identify inside the university extension education what does it mean for practitioners and extension activities and what results it produces to society and to the academic training of future professional citizens in the current neoliberal context. The research has been developed from an analytical and critical approach based on quantitative and qualitative data, using observation techniques and semi-structured interviews. We sought to investigate and understand the social reality, the main object of this work, with an interest in identifying the need for a new teaching/learning process and for a new university practice, in order to effectively improve an advanced academic formation. For this, some interviews have been conducted with teachers, students and the external community involved in extension actions in the period defined by the work, i.e., from 2008 to 2010. In this stage, it was observed that the academic work of university extension is essential to civic education. It was recognized too as a privileged space where university fulfills its social commitment towards society, as long as it joins scientific and popular knowledge having in view a new science and a new social order

Política externa no período FHC: a busca de autonomia pela integração

Durante o governo FHC buscou-se substituir a agenda reativa da política externa brasileira, dominada pela lógica da autonomia pela distância, por uma nova agenda internacional proativa, determinada pela lógica da autonomia pela integração. Segundo essa agenda, o país deveria ampliar o poder de controle sobre o seu destino e resolver seus problemas com uma adesão ativa à elaboração das normas e das pautas de conduta da gestão da ordem mundial. No entanto, essa política de integração, adesão e participação não foi plenamente acompanhada de tomadas de posições que implicassem responsabilidades práticas, em virtude de debilidades estruturais. As responsabilidades teriam como função preparar tanto o governo como a sociedade civil para uma inserção internacional de perfil mais elevado no pós-Guerra Fria. Os ganhos ocorridos nos governos FHC não foram suficientes para alterar significativamente o peso brasileiro no contexto mundial.

Influência da medicação pré-anestésica com midazolam e clonidina no nível de hipnose após indução anestésica com propofol e alfentanil em crianças: monitorização pelo índice bispectral

JUSTIFICATIVA E OBJETIVOS: A medicação pré-anestésica (MPA) é adjuvante da anestesia e diminui tanto a necessidade de concentrações elevadas de anestésicos como a ansiedade perioperatória, produzindo amnésia e contribuindo para estabilidade hemodinâmica. Dentre as drogas administradas na MPA de crianças, encontram-se o midazolam e a clonidina. O objetivo desta pesquisa foi avaliar se a MPA com midazolam e clonidina exerce influência no nível de hipnose, avaliado pelo BIS, em crianças após indução anestésica com propofol e alfentanil. MÉTODO: Participaram do estudo 30 pacientes, com idades entre 2 e 12 anos, estado físico ASA I, submetidos a cirurgias eletivas, que foram distribuídos em 3 grupos: G1 - sem MPA, G2 - midazolam (0,5 mg.kg-1) e G3 - clonidina (4 µg.kg-1), por via oral, 60 minutos antes da cirurgia. Todos os pacientes receberam alfentanil (30 µg.kg-1), propofol (3 mg.kg-1) e atracúrio (0,5 mg.kg-1). Avaliou-se o valor derivado do BIS antes da indução da anestesia (M1) e após a intubação (M2). O método estatístico utilizado foi a análise de variância para idade, peso e altura, e análise de perfil para o BIS, sendo o valor de p < 0,05 considerado significativo. RESULTADOS: Quando se comparou o mesmo momento (M1 ou M2) entre os três grupos, não foram observadas diferenças estatisticamente significativas. Quando se compararam os dois momentos de um mesmo grupo, M1 foi maior que M2 nos três grupos. CONCLUSÕES: A medicação pré-anestésica com midazolam e clonidina não influenciou o nível de hipnose em crianças induzidas com propofol e alfentanil.

Eficácia do propofol e da associação de propofol e dexametasona no controle de náusea e vômito no pós-operatório de laparoscopia ginecológica

JUSTIFICATIVA E OBJETIVOS: A laparoscopia ginecológica é procedimento que determina alta incidência de náusea e vômito no pós-operatório. Este estudo teve por finalidade comparar a eficácia do propofol isoladamente ou em associação com a dexametasona na prevenção de náusea e vômito em pacientes submetidas à laparoscopia ginecológica. MÉTODO: Participaram do estudo 40 pacientes, estado físico ASA I e II, com idades entre 18 e 46 anos, sem queixas gástricas prévias, submetidas à laparoscopia para diagnóstico ou cirurgia. As pacientes foram divididas em 2 grupos: o grupo 1 recebeu (solução fisiológica 2 ml) e o grupo 2 dexametasona (8 mg), por via venosa antes da indução da anestesia. Todas as pacientes receberam midazolam (7,5 mg) por via oral como medicação pré-anestésica, sufentanil (0,5 µg.kg-1), propofol em infusão contínua para indução e manutenção da anestesia (BIS - 60) e N2O/O2 em fração inspirada de O2 a 40% e atracúrio (0,5 mg.kg-1) como bloqueador neuromuscular. A analgesia pós-operatória foi realizada com cetoprofeno (100 mg) e buscopam composto ®.As pacientes fora avaliadas na sala de recuperação pós-anestésica (SRPA) e na enfermaria 1, 2, 3 e 12 horas após a alta da SRPA. RESULTADOS: Ambos os grupos foram idênticos quanto aos dados antropométricos e à duração da cirurgia e da anestesia. No grupo 1 (n = 20) uma paciente apresentou náusea na SRPA e na enfermaria e três pacientes vomitaram na enfermaria. No grupo 2 (n = 20) nenhuma paciente apresentou náusea ou vômito durante o período de observação clínica, resultados estatisticamente não significativos. CONCLUSÕES: O propofol isoladamente ou associado à dexametasona foi eficaz na prevenção de náusea e vômito no pós-operatório de pacientes submetidas à laparoscopia ginecológica

Eficácia da N-butilescopolamina e dipirona sódica associadas ao cetoprofeno no alívio da dor pós-operatória de pacientes submetidas a duas técnicas diferentes de laqueadura por laparoscopia

JUSTIFICATIVA E OBJETIVOS: A laqueadura laparoscópica (LL) é um dos procedimentos mais dolorosos e a intensidade da dor varia com a técnica selecionada, sendo mais intensa com a técnica de oclusão das tubas uterinas com anel. As pacientes submetidas à LL referem dor em cólica no período PO e a N-butilescopolamina e a dipirona sódica, por suas propriedades anti-espasmódicas e analgésicas, associadas às propriedades antiinflamatórias do cetoprofeno, podem ser opção para profilaxia e tratamento de dor. O objetivo deste foi estudar a eficácia da N-butilescopolamina e da dipirona sódica associadas ao cetoprofeno, na prevenção de dor PO em pacientes submetidas à LL, com duas técnicas diferentes - diatermia e pinçamento com anel. MÉTODO: Participaram do estudo 50 pacientes, estado físico ASA I e II, com idade entre 23 e 47 anos. As pacientes foram distribuídas aleatoriamente em dois grupos: G1 - oclusão das tubas uterinas com anéis, G2 - oclusão das tubas uterinas com diatermia. Todas as pacientes receberam N-butilescopolamina (20 mg) e dipirona sódica (2500 mg) e cetoprofeno (100 mg), por via venosa, imediatamente antes da indução da anestesia. A dor foi avaliada pelo critério de escala numérica verbal, variando de 0 a 10, sendo 0 ausência de dor e 10 o máximo de dor, a cada 10 minutos na primeira hora, na sala de recuperação pós-anestésica (SRPA) e na 1ª, 2ª, 3ª e 4ª horas após a alta da SRPA. Dor com intensidade maior que 3 era tratada com tramadol (100 mg), por via venosa. A avaliação da dor foi realizada sem que se soubesse a que grupo pertencia a paciente. Para análise estatística, testes t de Student, Mann-Whitney e Friedman. RESULTADOS: Ambos os grupos foram idênticos com relação à idade, ao peso, à altura, à duração da cirurgia e anestesia. As pacientes do G1 apresentaram maior escore de dor que as do G2, em todos os momentos do estudo. Valores estatisticamente significativos: 80% das pacientes de G1 e 16% de G2 necessitaram de tramadol em algum momento do estudo. CONCLUSÕES: A N-butilescopolamina e a dipirona sódica associadas ao cetoprofeno mostraram ser alternativa de analgesia pós-operatória quando a laqueadura é realizada com a técnica de diatermia.

Aspectos clínicos e laboratoriais em ovinos submetidos a dietas com níveis elevados de enxofre com objetivo de indução de polioencefalomalácia

A polioencefalomalacia (PEM) é uma doença neurológica que acomete ruminantes e pode ser desencadeada por diversos fatores, dentre eles o consumo excessivo de enxofre. Este trabalho teve como objetivo verificar a relação entre dietas ricas em enxofre, altos níveis de gás sulfídrico ruminal e a ocorrência de polioencefalomalácia em ovinos. Foram utilizados 18 ovinos, divididos em três grupos (G1, G2 e G3) que receberam diferentes níveis de enxofre na dieta; 0,2%, 0,9% e 1,2%, respectivamente. Exames físicos (frequência cardíaca, frequência respiratória, temperatura retal e motricidade ruminal) e complementares (concentração de sulfeto de hidrogênio ruminal, hemogasometria venosa, pH do fluído ruminal, concentração de cobre sérico e hepático, tomografia computadorizada, necropsia e histopatologia) foram realizados. A temperatura retal, a hemogasometria venosa e o pH do fluido ruminal permaneceram dentro dos valores de referência para a espécie. A motricidade ruminal estava diminuída nos grupos G2 e G3 em comparação com o G1 (controle). Quanto maior a ingestão de enxofre, menores foram os níveis de cobre sérico e hepático. Valores elevados de sulfeto de hidrogênio ruminal foram detectados nos grupos G2 e G3. Nenhum animal apresentou sinais clínicos de PEM. Nos exames de tomografia computadorizada, necropsia e exame histopatológico do sistema nervoso central (SNC), não foram observadas alterações compatíveis com PEM. É provável que algum outro fator esteja associado ao excesso de enxofre na dieta para o desenvolvimento de PEM em ovinos.

Ansiedade, a criança e os pais

JUSTIFICATIVA E OBJETIVOS: A ansiedade pré-operatória na criança é caracterizada por tensão, apreensão, nervosismo e preocupação e pode ser expressa de diversas formas. Alterações de comportamento no pós-operatório como enurese noturna, distúrbios alimentares, apatia, insônia, pesadelos e sono agitado podem ser resultado desta ansiedade. em algumas crianças, estas alterações persistem por até um ano. O objetivo deste trabalho é avaliar os aspectos envolvidos com a ansiedade que afeta a criança e os pais durante o período que antecede a cirurgia, bem como as intervenções, farmacológicas ou não, para reduzi-la. CONTEÚDO: O artigo aborda a ligação entre a ansiedade pré-operatória em crianças e as alterações de comportamento que podem ocorrer no período pós-operatório, bem como a influência de variáveis como idade, temperamento, experiência hospitalar prévia e dor. Medidas para reduzir a ansiedade pré-operatória na criança como a presença dos pais durante a indução da anestesia ou programas de informação e a utilização de medicação pré-anestésica também são revisadas. CONCLUSÕES: O período que antecede a cirurgia acompanha-se de grande carga emocional para toda família, sobretudo para a criança. Um pré-operatório turbulento significa, para muitas crianças, alterações de comportamento que se manifestam de forma variada e por períodos prolongados em algumas vezes. A presença dos pais durante a indução da anestesia e programas de preparação pré-operatórios para a criança e para os pais podem ser úteis para casos selecionados, levando em conta a idade, temperamento e experiência hospitalar prévia. A medicação pré-anestésica com benzodiazepínicos, em especial o midazolam, é claramente o método mais eficaz para redução da ansiedade pré-operatória em crianças e das alterações de comportamento por ela induzidas.

Urbanização turística em ponta negra: relações de força e processos sociais no período de 1979-2009

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Políticas públicas e as transformações socioespaciais correlacionadas ao turismo no município de Caicó: uma análise do período 2000 a 2010

The study presents an approach on planning, sociospatial transformations and public touristic policies implemented between 2000 and 2010 in Caicó, encompassing people from the government, private sector and the population of the municipality and informal traders who use the leisure facilities and services arranged in place. As the main goal, the research intends to analyze the performance of public and private sectors correlated to the touristic activity in Caicó city and their reflections in the process changes sociospatial. The dissertation is structured in order to carry out an investigation into the role of public policies to the development of a location with touristic potential, in this case, the municipality of Caicó; to investigate public policies implemented in the touristic industry of Rio Grande do Norte, particularly the actions of PRODETUR-Nordeste focused on the development of the tourism in the countryside, affecting particularly the region of Seridó region and the municipality of Caicó, and, finally, to check the main changes sociospatial verified in Caicó between 2000 and 2010. Cultural issues and certain natural beauties can be seen as attractions that can attract tourist demand, taking into consideration the awakening increasingly more evident quest by the tourist for knowledge of the peculiarities of the region. Several authors have worked in this view, pointing to the cultural aspects of the region as elements that are able to boost the touristic activity. The questions raised in this study was based on a literature, based mainly on authors like Beni, Dias, Cruz, Azevedo and Morais. To obtain the necessary data in the analysis, the methodological procedures used in intensive direct observation, using interviews, applied together with the public representatives who are acting as leaders of the political actions related to tourism in the municipality and members of the private sector related to tourism services such as lodging establishments, food and travel agency and, finally, the local people and informal traders benefited directly or indirectly, with the touristic resources and structure. These research agents were investigated by means of structured forms such as support for analysis. Was detected in the survey that the leisure facilities and services installed in the last decade in the city of Caico has a priority the population of the municipality, is necessary to emphasize that the residents interviewed perceive the importance of these tools for tourist activity. It was also found that the public sector is the main responsible for the observed changes. Therefore, proved to be relevant to study the role public private sector partnerships and population influences, considering that this analysis may contribute to the work of researchers, public administrators and businessmen, may serve as a norteador for planning and development of tourism in the city of Caico

O Turismo como um tema de pesquisa: um diálogo epistemológico a partir das produções dos programas de pós-graduação stricto sensu da Universidade Federal do Rio Grande do Norte, no período de 2007 a 2011

The study consists in an analysis of researches with tourism issues, in Master s and Doctoral level, investigating their epistemological trends, regarding the type of study that is being produced and the methods used. It is characterized as exploratory, documental and bibliographical, having undertaken a cross-sectional study which covers the period from 2007 to 2011. It analyzes the context of academically production in tourism, the nature of these researches, the methodological aspects adopted in these theses and dissertations, the philosophical inclinations and the coherence and contribution of the same. This research uses, the Digital Library of Theses and Dissertations (BDTD) and the secretariats of the Academic Centers of the Federal University of Rio Grande do Norte (UFRN) as means to collect data. It employs the technique of sampling by judgment and undertakes the research in various Academic Centers in UFRN, using the method of content analysis. It shows that, from the 643 studies analyzed, 43 of them have themes related to tourism, which characterized this study sample. This study realizes that PPGA is the largest producer of researches on tourism issues, ahead of PPGTur, which ranks the third position, in this aspect. Also realizes that all surveys analyzed are crosssectional and the theme further investigated, with 21% of the sample, is related to the marketing aspects of tourism, with the theme Directors of Hotels and Restaurants (DHR) . This research demonstrates that all sample surveys make use of interviews, and these are, mostly, structured. Also realizes that most of these studies, with 21% of the sample, employ the method of content analysis. The references in Portuguese are surveyed about five times more than the ones in other languages. It estimates that more than half of the sample is characterized as positivist, associated with aspects of functionalism. A minority of 21% of these researches seeks to identify and recommend solutions to the tourism issues, or even represent part of them. This research concludes that the studies in tourism are mostly unifocal, being driven by issues related to the touristic trade. PPGTur produces a number still unrepresentative of studies. The theses and dissertations of the sample are limited and/or unable to analyze the changes of the phenomenon caused by the time. The studies from the sample present criteria and make use of other methods and techniques to associate with the interviews and content analysis to obtain more solid and reliable data and results. They use a low number of references in languages other than Portuguese. Most of these studies, characterized as positivist-functionalist, investigate the functioning, planning, coordination and expectations in organizations, leaving aside other issues, also relevant for tourism. The number of studies aimed at identifying solutions to the problems of tourism, or that even represents part of them, is not expressive

Turismo, capital social e produção do espaço: uma leitura a partir do município de Natal/RN no período de 1980 a 2012

Nowadays, there is a tourism phase in the city of Natal/RN called internationalization of tourism , which shows a tourism model with a planning and an administration, based on the needs of the visitors. Such process shows that the production as well as the reproduction of the city spaces with the goal of favor tourism excludes of its composition the effective participation of local subjects. Thus, the research is a result of the perception of tourism as an activity with a meaningful power of transformation of the social and natural space taking into account the low participation of the residents in the decisions of the tourism activities in the city of Natal/RN. Despite that reality, it is possible to note Natal that civil society, starts to mobilize its citizens trying to develop collective actions to low the negative impacts caused by the bad planning as wells not efficient tourism administration, trying to put in action the right of the local population to take part in the decisions of the city activities. Having this panorama as background, this paper aims at investigating in which way the mobilizing action of the social capital in Natal has contributed to change the spatial production which is part of the process of expansion of tourism in Natal/RN? The research presents a temporal picture which starts in the year of 1980, when occurs the first effective state intervention aiming to develop tourism in the capital, taking into account an analysis of 2012. Concerning the spatial picture, the research investigates the beaches of Natal which concentrates criteria and actions such as: visitation, tourism appeal and focus of investments, highlighting the following beaches: Ponta Negra, Areia Preta, Praia dos Artistas, Praia do Meio, Praia do Forte and Redinha. This study is of a descriptive and exploratory nature concerning its goals. With respect to the treatment of its object it is a qualitative research. The data was collected through structural interviews, with open questions. Regarding the methodological choices, it was used the content analysis proposed as well as the collective discursive subject methodology. The results show that there´s not yet in Natal a meaningful social capital related to tourism, capable to change the spatial production related to the activity. It should be stressed that Natal social capital presents difficulties concerning the incentive to trust, spontaneous cooperation and the civic participation, which are the foundation for the development of an effective social capital, which makes it harder for a more expressive articulation in the reality in Natal/RN. It should be stressed, as an answer to the research questions, that tourism in Natal/RN is represented by social and spatial segregation. In other words it emphasizes mainly the action of hegemonic agents (State and market), leaving little room for the participation of society. It can be noticed that the actions related to tourism in Natal keeps the popular participation out of the way. Thus, it can be said that the social capital in Natal/RN does not yet contribute to a more fair spatial production related to the expansion of the tourism as well as the well being of the population of Natal/RN. In conclusion, it should be taken into account that this participation do exists but not in a meaningful way. In other words, it´s not enough yet to cause meaningful changes in the actions which tourism needs nowadays in Natal/RN

Avaliação econômica dos incentivos fiscais e financeiros: uma análise das empresas industriais têxteis localizadas no Rio Grande do Norte, no período de 1999 a 2003

This study has as main objective to verify the effect of the tax and financial incentives granted by the brazilian states, specially in the reduction of ICMS on the investment decision of the entities, which in the last years led to the companies to decide new projects in based on the region that presented the better infrastructure beyond lesser tributary expense. For in such was made an economic valuation of the companies with focus in the beneficiary s optics using an adaptation of the Discounted Cash Flow method to measure the impact of the tax incentives in the value of the companies, this study selected the textile industry segment located in the State of Rio Grande do Norte, Brazil. The results indicated that such incentives created addition in the value of the companies, however the inexistence of incentives would not be enough to a negative decision of investment in the Rio Grande do Norte. The smallest difference between the value with and without incentive observed was 8.9%, and the biggest 31.7%, and the average of value aggregation with the tax incentives represented 18.9%
