Resistência e performance na arte de João Cota

Researching about the art of tell and the tales told by João Cota is somehow revisiting the oral tradition and social practice in the story-telling art. It takes into consideration the resistance this art still exerts, mainly by using the performance of oral transmission and receptiveness to tales. The study of this practice contributes to the vivacious and dynamcis permanence of this authentic and traditional storyteller of his repertory and of his form to tellin our culture. Story-telling is part of the humankind living heritage communicated by means of popular wisdom. Despite the risk of vanishing into thin air, along with their narrators, the tales still manage to resist the contemporary mass culture model. How long further will stories like the ones narrated by João Cota be able to resist to strong and stronger structures dictated by writing and other communication means? João Cota s practice in story-telling will be studied not only as a proposal to identify the presence of this practice and the oral cultural resistance but also, through the performance prospective, to identify the oral transmission and receptiveness to the tales that are part of this storyteller s repertoire. In other words: what he tells, how he tells it, and why he tells it. The advent of new technologies such as internet, through which people can easily communicate with others in different parts of the world, and the greater and greater expansion in the writing skill concept interfere the maintenance of the oral tradition elements present in João Cota s narratives and inserted in the Brazilian culture. This has become more visible in the latest decades although we still notice the living tradition and permanence of the story-telling practice in several parts of the country through their wise storytellers. Our research target will require - in each of its study stages reference to works by several theoreticians namely Paul Zumthor, Mikhail Bakhtin, Câmara Cascudo, theoreticians from the receptiveness aesthetic, from the written culture history, from oral cultures and reading practices, from tradition and the Brazilian Culture of oral story-telling. In order to get to know and draw a profile of this storyteller, we ve chosen to use the comprehensive interview method by French Sociologist Jean Claude Kaufmann. The originality in the method consists of the qualitative data put together in situ , concentrated on the storyteller s narratives/speeches recorded on tape, which will be the focal point of this study. Our analysis method is based on tireless sessions of listening to interviews out of which we gathered information related to the storyteller, his practice in telling the tales, and his repertoire

Interpretação e análise do problema da indução sob uma visão fundamentada em teorias de conjuntos e teoria de probabilidades

The following work is to interpret and analyze the problem of induction under a vision founded on set theory and probability theory as a basis for solution of its negative philosophical implications related to the systems of inductive logic in general. Due to the importance of the problem and the relatively recent developments in these fields of knowledge (early 20th century), as well as the visible relations between them and the process of inductive inference, it has been opened a field of relatively unexplored and promising possibilities. The key point of the study consists in modeling the information acquisition process using concepts of set theory, followed by a treatment using probability theory. Throughout the study it was identified as a major obstacle to the probabilistic justification, both: the problem of defining the concept of probability and that of rationality, as well as the subtle connection between the two. This finding called for a greater care in choosing the criterion of rationality to be considered in order to facilitate the treatment of the problem through such specific situations, but without losing their original characteristics so that the conclusions can be extended to classic cases such as the question about the continuity of the sunrise

Descrição de dieta purificada para indução de quadro de desnutrição protéica em ratos

No presente trabalho é descrita a composição de dieta hipoprotéica (6% de proteína) purificada para indução de quadro de desnutrição em roedores. A referida dieta foi padronizada em laboratório a partir de modificação da AIN-93 (documento do American Institute of Nutrition que estabelece os padrões nutricionais para roedores de laboratório), visando a obtenção de animais desnutridos para estudar as alterações metabólicas decorrentes da desnutrição protéica associada a situações como exercício físico, gestação e diabetes. A dieta em questão contém os seguintes componentes (g/ kg): amido de milho (480), caseína (71,5), dextrina de milho (159), sacarose (121), óleo de soja (70), microcelulose (50), mistura mineral AIN-93-G-MX (35), mistura de vitaminas AIN-93-G-VX, (10), L-cistina (1), cloridrato de colina (2,5). Ratos alimentados cronicamente com a dieta apresentaram sinais comumente presentes na desnutrição protéica humana e de animais de laboratório: redução do ganho de peso, hipoproteinemia, hipoalbuminemia, elevação dos ácidos graxos livres séricos e do glicogênio hepático.

Prospecção e caracterização de genes associados ao processo de indução floral em cana-de-açúcar

The northeastern region is responsible to 14.32% of sugarcane national production. This lowered contribution is due to edaphoclimatic condition. Flowering is a vital process to plant which consumes lots of energy and it culminates in a process called isoporization. This one can give in a decreasing of 60% on alcohol and water production. It may consider that cropped sugarcane has a hibrid with octaploid genome, there are varieties with a flowering standard until of non flowering. Using this natural genetic potential on different croppings of sugarcane, the aim of this work was to understand as this process occurs by the usage of subtractive approaches. The total RNA was extracted using Trizol of peaks of merisematics of croppings with induced flowering and other with late flowering. From this total RNA were built four subtractives libraries (B1- induced early flowering subtracted on late flowering not induced; B2- late flowering not induced subtracted induced early flowering; B3- induced early flowering subtracted of not induced early flowering; B02- not induced early flowering subtracted from induced early flowering) using kits Super Smart cDNA synthesis and BD Clontech kit select cDNA subtraction (Clontech). This material was clone don vector pGEM T-easy(Promega) and changed in competent cells of E.coli DH10B. Given analysis sequence was carried out a program BLASTn against database of NCBI and genome of Arabidopsis thaliana, rice and maize. Clones were grouped in 9 different classes according to function. Some factors already related as couples of flower induction were identified at different libraries. And grouped proteins with cell cycle and it controls were presents, mainly kinases proteins. Related factors to proteic sinthesis, metabolism, defence, cell communication were also given in both libraries .Some identified genes did not show similarity on database or homology with hypothesis function, and it can represents new genes to be deposited in international database. These results offers that some identified on sugarcane, classified as on factors classes, cell cycle and cell communication, trough unknown genes, can be linked with genetic changing to the flowering process found in the northeastern region

Caracterização da resistência do algodoeiro a Ramularia areola e variabilidade molecular do patógeno

This research was conducted with the aim to study the genetic and pathogenic structure of Ramularia areola isolates collected in Brazil and to characterize the resistance response in cotton plants to ramularia spot. The genetic variability of 28 isolates of R. areola was studied using RAPD markers. The pathogenicity evaluation was realized by the inoculation of 6 isolates on cotton varieties Guazuncho-2 (Gossypium hirsutum) and VH8-4602 (Gossypium barbadense). The inheritance of disease resistance was studied using an artificially inoculated population of F2 individuals derived from the intercross of Guazuncho-2 (susceptible variety) end VH8-4602 (resistant variety), and also the parents and F1 individuals. Molecular polymorphism between the G. hisutum varieties DeltaOpal (suscetible) and CNPA CO-11612 (resistant) was estimated by 118 SSR and 24 AFLP markers. The parental genotypes Guazuncho-2 and VH8-4602 were selected for mapping, and then Recombinant Inbred Lines (RIL´s) derived from this crossing were evaluated with SSR 12 markers. The analysis of population structure of R. areola revealed that the three subpopulations were genetically simillar (Gst=0.18), and the isolates from Goiás and Minas Gerais were more similar to each other (0,92). This probability can be related to the relatively high gene flow among the three subpopulations (Nm=2.20). The isolates R. areola 9.1, from Minas Gerais State and 8.1 and 8.3 from Goiás State were the most aggressive ones to the susceptible variety Guazuncho-2. The variety VH8-4602 presented high level of resistance to ramularia spot. No differential interaction was observed between the pathogens and the analyzed varieties, and the resistance was classified as horizontal. The quantification of disease by number of necrotic lesions and number of spores in individual plants of F1 and F2 generations from the crossing between the varieties Guazuncho-2 and VH8-4602 presented continuous distribution, suggesting polygenic resistance. The resistance is probabilly recessive, since necrotic lesions and sporulation were observed on F1 plants. The molecular polymorphism between DeltaOpal e CNPA CO-11612 lineages was low (6%), then would be difficult to accomplish molecular mapping of disease resistance using this intercross. With the genotyping of the RIL s it was verified that 25% of the markers segregated in the proportions proposed by Mendel s Law and 75% of the studied markers presented segregation distortion in favor to the parental G. hirsutum. Both the low genetic variability of the pathogen and the number of resistance genes suggest that durable genetic resitance may be achieved

Caminhos para a universalização dos serviços de água e esgotos no Brasil: a atuação das entidades reguladoras para indução da eficiência dos prestadores de serviços

The deficit of water and sewerage services is a historic problem in Brazil. The introduction of a new regulatory framework, in 2007, presented ways intending to overcome these deficits, among them, the providers efficiency improvement. This thesis aims to analyze the regulators performance regarding its ability to induce the efficiency of the Brazilian water and sewerage services providers. To this end, an analytical approach based on a sequential explanatory strategy was used, and it consists of three steps. In the first step, the Data Envelopment Analysis ( DEA ) was used to measure the providers efficiency in 2006 and 2011. The results show that the average efficiency may be considered high; however significant inefficiencies among the 29 analyzed providers were detected. The ones in the Southeast region showed better performance level and Northeast had the lowest. The local and the private providers were more efficient on average. In 2006 and 2011 the average performance was higher among non-regulated providers. In 2006 the group regulated by local agencies had the best average performance, in 2011, the best performance was the group regulated by the consortium agencies. To analyse the second step was used the Malmquist Index, it pointed that the productivity between 2006 and 2011 dropped. The analysis through decomposing Malmquist Index showed a shift of technical efficiency frontier to a lower level, however was detected a small provider s advance towards the frontier. Only the Midwest region recorded progress in overall productivity. The deterioration in the total factor productivity was higher among regional providers but the local ones and the private agencies moved quickly to the frontier level. The providers regulated from 2007 showed less decrease on the total productivity and the results of the catch up effect were more meaningful. In the last step, the regulators standardization activity analyses noted that there are agencies that had not issued rules until 2011. The most standards topics discussed in the issued rules were the tariff adjustments and the setting of general conditions for the provision and use of services; in another hand, the least covered topics were new technologies incentive and the introduction of efficiency-inducing regulatory mechanisms and productivity gains for price reviews. Regulators created from 2007 were more active proportionately. Even with the advent of the regulatory framework and the creation of new regulatory bodies, the evidence points to a reality in which the actions of these agencies have not been ensuring that providers of water and sewage, regulated by them, has achieved better performance. The non- achievement of regulatory goals can be explained by the incipient level of performance of the Brazilian regulatory authorities, which should be strengthened because of its potential contribution to the Brazilian basic sanitation department

Marcadores fenotípicos para caracterização de caprinos com diferentes níveis de resistência às endoparasitoses gastrintestinais

The aim of this study was to evaluate and characterize phenotypically goats with different levels of resistance to gastrointestinal nematodes. For a period of 93 days, 60 F2 goats originated from ½ Saanen and ½ Anglo- nubian animals were kept in the same area of pasture. Every seven days, feces and blood were collected for eggs per gram counts of feces (EPG) and cultures of feces and to determinate the number of eosinophils, packed cell volume and total plasma protein, respectively. On the same day, the animals were weighed and submitted to body score condition and FAMACHA method to worm control. Based on the average of EPG, the twelve animals with the highest average (susceptible group) and the twelve animals with the lowest average of EPG (resistant group) were selected, slaughtered and necropsied to recovery, counting andparasites identification. The resistant animals present lower EPG mean (P <0.0001) and 4.7 folder less parasites than susceptible animals. The resistant group presented higher mean packed cell volume (26.48%) and total plasma protein (6.24 g / dl) than susceptible one (24,04% e 5,82g/dl, respectively). The average number of eosinophils was similar in both groups The Haemonchus sp. was the most prevalent in the culture of feces, followed by Trischostrongylus sp. and Oesophagostomum sp.. The counting of nematodes in the abomasum of susceptible group was higher than in resistant one. The species identified were H. contortus in abomasums and T. colubriformis in small intestine. It can be concluded that EPG, packed cell volume and total plasma protein were useful phenotypic markers to identify animals as resistant and susceptible to gastrointestinal nematodes infections

Estimação de parâmetros genéticos para resistência à infecção por IMNV em camarões Litopenaeus vannamei por meio de análise de sobrevivência

The main specie of marine shrimp raised at Brazil and in the world is Litopenaeus vannamei, which had arrived in Brazil in the `80s. However, the entry of infectious myonecrosis virus (IMNV), causing the infectious myonecrosis disease in marine shrimps, brought economic losses to the national shrimp farming, with up to 70% of mortality in the shrimp production. In this way, the objective was to evaluate the survival of shrimps Litopenaeus vannamei infected with IMNV using the non parametric estimator of Kaplan-Meier and a model of frailty for grouped data. It were conducted three tests of viral challenges lasting 20 days each, at different periods of the year, keeping the parameters of pH, temperature, oxygen and ammonia monitored daily. It was evaluated 60 full-sib families of L. vannamei infected by IMNV in each viral challenge. The confirmation of the infection by IMNV was performed using the technique of PCR in real time through Sybr Green dye. Using the Kaplan-Meier estimator it was possible to detect significant differences (p <0.0001) between the survival curves of families and tanks and also in the joint analysis between viral challenges. It were estimated in each challenge, genetic parameters such as genetic value of family, it`s respective rate risk (frailty), and heritability in the logarithmic scale through the frailty model for grouped data. The heritability estimates were respectively 0.59; 0.36; and 0.59 in the viral challenges 1; 2; and 3, and it was also possible to identify families that have lower and higher rates of risk for the disease. These results can be used for selecting families more resistant to the IMNV infection and to include characteristic of disease resistance in L. vannamei into the genetic improvement programs

Avaliação termoanalítica da eficiência de antioxidantes na estabilidade oxidativa do biodiesel de mamona

The biodiesel is defined as the mono-alkyl ester derived from long-chain fatty acids, from renewable sources such as vegetable oils or animal fat, whose use is associated with the replacement of fossil fuels in diesel engine cycle. The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly due to long periods of storage. Because of this, the oxidation stability has been the focus of numerous researches since it directly affects the producers, distributors and users of fuel. One of the possibilities to increase the resistance of biodiesel is the autoxidation treatment with inhibitors of oxidation. The antioxidants can be used as potential inhibitors of the effects of oxidation on the kinematic viscosity and the index of acidity of biodiesel, thereby increasing oxidative stability. This work aims to examine the efficiency of antioxidants, α-tocopherol and butylated hydroxy-toluene (BHT), added the biodiesel content of remembrance through Pressurized-Differential Scanning Calorimetry (P-DSC), Thermogravimetry (TG) and Petrology. The results showed that the use of antioxidant BHT, at the concentration of 2000ppm, increased resistance to oxidation of the biodiesel and oxidative induction time (OIT), which is a better result as antioxidant than the α-tocopherol. With the thermogravimetric analysis, it was observed that the biodiesel presented an initial decomposition temperature of lower tendency than that of oil, demonstrating to be more volatile, bearing great similarity to the diesel and being characterized as an alternative fuel. The rheological analysis indicated that each sample of biodiesel behaved as a Newtonian fluid

Produtividade da soja e resistência mecânica à penetração do solo sob sistema plantio direto no cerrado brasileiro

A resistência mecânica à penetração do solo pode influenciar, negativamente, o crescimento radicular da soja, afetando, sobremaneira, sua produtividade. No ano agrícola 2008/2009, no município de Selvíria (MS), no Cerrado brasileiro, foi analisada a produtividade da soja, em função da resistência mecânica à penetração de um Latossolo Vermelho distroférrico, no sistema de semeadura direta. O objetivo foi selecionar, entre os atributos pesquisados do solo, aquele com a melhor correlação, linear e espacial, para explicar a variabilidade da produtividade da soja. Foi instalada uma malha geoestatística, para a coleta de dados do solo e da planta, com 120 pontos amostrais, em área de 8,34 ha e declive homogêneo de 0,055 m m-1. Dessa forma, visando-se a auxiliar futuros trabalhos voltados à agricultura de precisão, os quais venham a utilizar os mesmos atributos do presente estudo, os valores dos alcances da dependência espacial a serem empregados deverão estar compreendidos entre 38,1 m e 114,7 m. do ponto de vista linear, a resistência mecânica à penetração do solo, quando avaliada na camada 0,10-0,20 m, apresentou boa correlação exponencial inversa com a produtividade de grãos de soja. Entretanto, do ponto de vista espacial, o número de vagens por planta apresentou-se como bom indicador da produtividade de grãos de soja.

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.

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.
