Efeito inseticida de vicilinas isoladas de sementes de erythrina velutina em condições de semi-campo para moscas das frutas (ceratitis capitata)

Chitin-binding vicilins from legume seeds (Erythrina velutina. Canavalia ensiformes and Phaseolus vulgares) were isolated by ammonium sulfate followed by affinity chromatography on a chitin column. Effect of these vicilins on female adults of Ceratitis capitata was examined by bioassay and in a semi-field assay model. Mechanism of action of the vicilins was determined by in vivo digestibility and chitin affinity. Among the tested vicilins, E. velutina when added to diet caused strong effect on mortality at 10% dose. This insecticidal property was tested in a semi-field assay which showed the same effect observed in laboratory conditions, where doses of 10% and 15% were lethal to female adults of C. capitata. These deleterious effects were not only associated to the binding to chitin structures present in peritrophic membrane, but principally to its low digestibility in the C. capitata digestive tract. This fact was confirmed because chiting binding proteins as WGA and the other tested vicilins were not toxic to female adults of C. capitata due susceptibility of these proteins to digestive enzymes of the insects. By other side EvV was more resistant to digestive enzymes, causing deleterious effects on female adults of C. capitata. These results showed that EvV may be part of the pest management programs or an alternative in plant improvement program in the population control of this fruticulture pest

Uma aplicação da apredizagem por reforço na otimização da produção em um campo de petróleo

The objective of reservoir engineering is to manage fields of oil production in order to maximize the production of hydrocarbons according to economic and physical restrictions. The deciding of a production strategy is a complex activity involving several variables in the process. Thus, a smart system, which assists in the optimization of the options for developing of the field, is very useful in day-to-day of reservoir engineers. This paper proposes the development of an intelligent system to aid decision making, regarding the optimization of strategies of production in oil fields. The intelligence of this system will be implemented through the use of the technique of reinforcement learning, which is presented as a powerful tool in problems of multi-stage decision. The proposed system will allow the specialist to obtain, in time, a great alternative (or near-optimal) for the development of an oil field known

Contribuição da catodoluminescência para o entendimento da diagênese da formação Jandaíra: áreas do campo de petróleo da fazenda Belém e Lajedo do Rosário

The general objective of this study was to contribute to the understanding of the chemical evolution of fluids that percolate through carbonate rocks of the Jandaíra Formation. The oxidation and reduction conditions in which grains, source and cement were formed was investigated using the cathodoluminescence technique (CL). The study area is located in the west part of the Potiguar Basin (Fazenda Belém field) and Rosário Ledge (Felipe Guerra municipality, State of Rio Grande do Norte, Brazil). The analysis of thin sections of carbonate rocks under CL revealed that grains (allochemical or not) and diagenetic products (micritization, dolomitization, neomorphism and cementation) exhibit since absence of luminescence the various luminescence colors (yellow, orange, red, brown, and blue) in a variety of intensities. As pure calcite shows dark blue luminescence, the occurrence of different luminescence colors in calcite crystals suggest one or more punctual crystal defects such as free electron, free space and impurity. The dyeing of thin sections with alizarin and potassium ferrocyanide revealed the absence of ferrous carbonate in the different lithotypes of Jandaíra Formation. Therefore, the different colors and intensities of CL observed in these rocks are probably caused by the presence of ion activators such as Mn2+ and is not an activator/inhibitor combination. In the same way, the absence of luminescence is very probably caused by the absence of activator ions and not due to the low concentration of inhibitor ions such as Fe2+. The incorporation of Mn2+ in the different members of the Jandaíra Formation must have been controlled by the redox state of the depositional environment and diagenesis. Therefore, it is possible that the luminescent members have been formed (e.g.,ooids) or have been modified (gastropod neomorphism) under reduction conditions in the depositional environments, in subsurface during the burial, or, in the case of Rosario Ledge samples , during the post-burial return to surface conditions. As regards the sudden changes from low to moderate and to strong luminescence, these features should indicate the precipitation of a fluid with chemical fluctuations, which formed the frequent zonations in the block cement of the Rosario Ledge samples. This study suggests that the different intensities and colors of CL should be correlated with the Mn2+ and Fe2+ contents, and stable isotopes of samples to determine the salinity, temperature, pH e Eh conditions during deposition

Estudos hidroquímicos da água produzida de um determinado campo de petróleo da bacia potiguar

Waste generated during the exploration and production of oil, water stands out due to various factors including the volume generated, the salt content, the presence of oil and chemicals and the water associated with oil is called produced water. The chemical composition of water is complex and depends strongly on the field generator, because it was in contact with the geological formation for thousands of years. This work aims to characterize the hydrochemical water produced in different areas of a field located in the Potiguar Basin. We collected 27 samples from 06 zones (400, 600, 400/600, 400/450/500, 350/400, A) the producing field called S and measured 50 required parameter divided between physical and chemical parameters, cations and anions. In hydrochemical characterization was used as tools of reasons ionic calculations, diagrams and they hydrochemical classification diagram Piper and Stiff diagram and also the statistic that helped in the identification of signature patterns for each production area including the area that supplies water injected this field for secondary oil recovery. The ionic balance error was calculated to assess the quality of the results of the analysis that was considered good, because 89% of the samples were below 5% error. Hydrochemical diagrams classified the waters as sodium chloride, with the exception of samples from Area A, from the injection well, which were classified as sodium bicarbonate. Through descriptive analysis and discriminant analysis was possible to obtain a function that differs chemically production areas, this function had a good hit rate of classification was 85%

Metodologias estatísticas aplicadas a dados de análises químicas da água produzida em um campo maduro de petróleo

Produced water is characterized as one of the most common wastes generated during exploration and production of oil. This work aims to develop methodologies based on comparative statistical processes of hydrogeochemical analysis of production zones in order to minimize types of high-cost interventions to perform identification test fluids - TIF. For the study, 27 samples were collected from five different production zones were measured a total of 50 chemical species. After the chemical analysis was applied the statistical data, using the R Statistical Software, version 2.11.1. Statistical analysis was performed in three steps. In the first stage, the objective was to investigate the behavior of chemical species under study in each area of production through the descriptive graphical analysis. The second step was to identify a function that classify production zones from each sample, using discriminant analysis. In the training stage, the rate of correct classification function of discriminant analysis was 85.19%. The next stage of processing of the data used for Principal Component Analysis, by reducing the number of variables obtained from the linear combination of chemical species, try to improve the discriminant function obtained in the second stage and increase the discrimination power of the data, but the result was not satisfactory. In Profile Analysis curves were obtained for each production area, based on the characteristics of the chemical species present in each zone. With this study it was possible to develop a method using hydrochemistry and statistical analysis that can be used to distinguish the water produced in mature fields of oil, so that it is possible to identify the zone of production that is contributing to the excessive elevation of the water volume.

O erotismo mítico da ninfeta

This dissertation establishes a viewpoint in the Social Cience Field of the Nymphs image in the romanesque construction of the twentieth century based in modern archaeology. Our literary corpus is constitututed by the book of the russian author callled Wladimir Nabokov entlited Lolita and the book Presença de Anita, from a brazilian author called Mario Donato. Both works had a singular repercussion involving an erotic conception wich was faced as pornographic and baffling. We appeal to Georges Bataille‟s and Foucault‟s discussion in order to observe it through an erotic viewpoint from an inner experience not submitted to normalizations. Such experiences provoke a feeling of something unknown and it reflects wild singularities proposed by Foucault and related with many misunderstanding things presented in institutions and cultures. Furthemore Bataille‟s conception about erotism will give us conditions to analyze nymphs‟ bodies in order to see themselves from their main characteristics, such as seduction and tempting and maligning forces. We still aim to focus the paradigm of mankind and nature in the direction presented by Edgar Morin. He analyzes some feelings that nymphs provoke and their relation between men and death. In adittion, we present in this issue some questions between culture and biology, focusing on the initial period of larva (wich means the beggining), bringing up what is ready to be born, a mythical and significant body shown in the media. Lolita in the cinema and A Presença de Anita in the TV was disturbing in society and it projected the possibility of a syntaxes of desire. It can has a symbolic purpose or it can be a kind of social and cultural phenomenon, wich is an object of representation. Our purpose is to immersion/emerge in the Nimphs‟s body with adventure and its risks at the same time in wich we are crossing frontiers

Campo e contracampo : o encontro com o outro no filme Lavoura Arcaica

This dissertation aims to comprehend how we meet with the other at cinema. For this, it receives the doubt, the uncertainty, the way that the human being is unfinished as stance of observation. It takes into consideration the multiples social vectors, historical, subjective, temporal and cultural which constitute these phenomena. The cinema is used as a cognitive resource in order to incorporate the poetic and the imaginary, making possible not forgetting gestures and knowledge that hatch from sounds, colours, remembrances, images, words, social exchanges, cognitive reciprocity that allow us to think about the culture, the society and the communication. For this, it has as theoretical prerequisites ideas of double (myselfthe other) and effective participation (projection-identification) developed by Edgar Morin, as well as the idea of communication as possibility/impossibility of constructions of bonds with the other through the body, our primary media, concepts developed by Harry Pross and Norval Baitello Jr. The chosen film to analysis is Lavoura Arcaica, it is an emblematic movie in the discussion of the human condition and in the relationship between the man and its body, its desires, with its nature/culture ambivalence. About this film are made reflections about the process of activation of the double (myself-the other) in the searching for the other through cinematographically elements of construction, as: montage, direction, screenplay, actors, scenography, costumes and soundtrack. In conclusion, the cinema, when it allows the effective participation and provides t e experiment of the double, becomes a gateway line in the path to development of the alterity

Práticas clientelistas e dádivas como estratégias de hegemonia política: uma análise sobre o campo da saúde em Mossoró-RN

The reality experienced by many families and individuals who seek and require the services of the Unified Health System - SUS, the relationships between users, health professionals, and political representatives, establishes the core of the issue that guides the choice and interest of this study concerning the prominence of clientelist practices and gifts that permeate the health field. The research is based on the analysis and reflection of the intrinsic relationship between the health and political fields. It analyses the health field and its relationship with the dynamics and developments of the local political scenario relating it to the implementation of the Family Health Program and Community Health Agents Program (PACS/PSF health programs) in the city of Mossoró, State of Rio Grande do Norte which refers to the period 1991-2010; and falls into a methodological perspective of qualitative approach. The methodological tools and techniques used were based on semi-structured interviews, direct observation of the field, journalistic texts and documentary sources. The construction and questioning of the object of the research were based on theoretical contributions from authors discussing the social field and symbolic power: Bourdieu (2005); clientelist relationships and gifts from asymmetric exchanges: Rouland (1997), Lanna (1995), Martins (1999), Carvalho (1999), Diniz (1982); exercise of hegemony and political strategy from authors who analyse this subject: Gramsci (1995), Coutinho (1981), and Gruppi (1978). Furthermore, the research has established dialogues with authors who address the dynamics of Brazilian politics such as Baquero (2001) and Weffort (1993). The collected data were subjected to qualitative content analysis. The results showed that with the implementation of the PACS/PSF programs in the aforementioned city, the health field has established itself as a key scenario for the exercise of political hegemony of the factions that dominate this socio-political context, resizing clientelist practices, however, without modifying the power structures within this social scenario

Preferência para oviposição de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em genótipos de soja, sob condições de campo

Dez genótipos de soja: IAC 100, IAC 74-2832, IAC 90-2971, IAC 78-2318, PI 227687, PI 229358, PI 274454, BR-82 12547, MG/BRS-68 (Vencedora) e FT-5 (Formosa), foram avaliados quanto a resistência, do tipo não-preferência para oviposição, à mosca-branca, Bemisia tabaci (Genn.) biótipo B. O ensaio foi realizado no campo experimental da FCAV/UNESP, Jaboticabal-SP, de outubro de 1999 a janeiro de 2000. Pretendeu-se, ainda, verificar a preferência de oviposição da referida espécie em relação às folhas unifolioladas e trifolioladas, e quanto à posição do folíolo na folha trifoliolada, e estabelecer o número mínimo de folíolos necessários para amostrar adequadamente a oviposição da mosca branca. Constatou-se que a oviposição foi menor nos genótipos BR-82 12547 e IAC 74-2832 em todas as avaliações (15, 30, 45, 65 e 85 dias após a emergência das plantas). As maiores taxas de oviposição ocorreram em IAC 90-2971, IAC 100, PI 227687 e PI 274454. O número médio de ovos depositados por seção de folha pelas fêmeas de B. tabaci biótipo B nas folhas trifolioladas não diferiu significativamente dos obtidos nas unifolioladas, 15 dias após a emergência das plantas (estádios de desenvolvimento entre V3 e V5), em 70% dos genótipos. Quanto à posição dos folíolos, a mosca-branca ovipositou indistintamente sobre os folíolos mediano e laterais. Também o número médio de ovos depositados por área foliar, pela mosca-branca, nos três folíolos da folha trifoliolada não diferiu significativamente da média obtida para dois ou um folíolo desta, o que sugere ser, um folíolo, uma unidade amostral representativa da oviposição de B. tabaci biótipo B em soja.

Nas veredas por reconhecimento social: o papel da educação na desconstrução da inferioridade dos sujeitos do campo.

En la travesía por nuevos caminos en la investigación académica, se nos presenta el desafío de investigar alternativas que muestran un horizonte de posibilidades concretas de una educación pautada en la dinámica de organizaciones y movimientos que participan de la lucha por un proyecto de reconocimiento social y desconstrucción de la inferioridad de los sujetos del campo. El escenario de participación de la vida de los que integran la investigación como investigados e investigador es el Territorio Sertão do Apodi, localizado en el estado de Rio Grande do Norte, cuya elección empírica fue motivada por la fuerte presencia y participación de movimientos sociales en el campo. La propuesta es investigar posibilidades y desafíos de prácticas y acciones educativas tanto dentro como fuera de la escuela que buscan reconocer y dar visibilidad a los sujetos sociales del campo en el referido Territorio. Así, será objeto de nuestra investigación el espacio de tomada de decisiones y de organización de institucionalidad territorial a través de la actuación del Colegiado del Territorio del Sertão do Apodi y de las prácticas educativas resultantes de las demandas de las acciones territoriales, tanto escolares como no escolares. La literatura en la cual sedimentamos las bases teóricas fundamentales de esta investigación es la de Axel Honneth (2001; 2003), asociada al pensamiento de Boaventura Santos (2003; 2008a), Jesse Souza (2003, 2006) y Milton Santos (2006, 2007, 2009). Vale destacar, aún, la interlocución con la narrativa de Guimarães Rosa, a través de la obra Grande Sertão: Veredas, sobrepasando todo el conjunto del texto. Con esta intención, procuramos defender que una perspectiva de educación destinada a los sujetos del campo debe pautarse en la superación de la condición de invisibilidad social, a que estos están sometidos, por medio de una postura de reconocimiento social que se afirma en el ejercicio de la democracia participativa y en la reparación de desigualdades sociales. Para esto, son muchos los desafíos y las vulnerabilidades de este proceso; y desde ahí, abriremos caminos para lograr el reconocimiento del papel de la educación y el fortalecimiento de las identidades sociales, al situar al sujeto socialmente, permitiendo que se localice en un determinado grupo social, frente a los saberes construidos en la sociedad

A literatura na sala de aula: uma alternativa de ensino transdisciplinar

The present thesis studies the appropriate education of the literary gender based in an approach of trans-disciplinary teaching. The main objectives will be to survey the degree of trans-disciplinarity of the literary reading in classrooms and to propose the literary reading as an alternative of trans-disciplinary teaching. The theoretical contributions, which sustain the lines of central argument of this thesis, are related to the critical theories on the epistemological and methodological crisis in the speech of the modernity; the emergency of an emerging paradigm under the optics of the speech of the post-modernity; the theories concerned to curriculums and their interrelations with the school teaching; the theories of the complexity and of the inter and trans-disciplinarity; theories of the reading and of the literature, more precisely the literary semiology and the aesthetics of the acceptance; theories about the pedagogic mediation starting from presupposed and trans-disciplinary principles. The methodological foundations, of the type inter and trans-disciplinary, which anchor the approach of the study is related to a line of qualitative analyses applied the teaching-learning situation accomplished during the data collection during the empiric stage of the research. The analyzed corpus is composed of episodes originated from the classes with literary texts accomplished in the months of June and December of 2005, under the orientation of a complex and trans-disciplinary didacticism. The involved subjects are students in the age group of 9 and 13 years of age from a public school in the county of Cabo de Santo Agostinho, in the State of Pernambuco. Starting from the discoveries found during the research, so much bibliographical, as that of the field, it is possible to conclude, among other things, that the literary reading, when mediated accordingly in the classroom, is a trans-disciplinary object of high degree, because the literary reading can allow and make it possible to the real reader, through a necessary process of speculation on life and its unfolding, solid reflection around the individual and collective occurrences so much in simpler instances as in more complex ones

As mudanças da educação do RN nos idos de 1950 e 1960 :a prática de Lia Campo

The present study investigates and analyzes the participation of the teacher Lia Campos, during the 50 s and 60 s years, in the norte-riograndense educational organization. The choice of the period is justified because was at this the time what this teacher remained in the potiguar lands, working in favor of the education. In the search of data that informed me concerning her actions, I cover quantities as the Public Archive of the Great River of the North, Historical Institute and Geographic of the Rio Grande do Norte and the Center of Supplementary Studies Teacher Lia Campos, in the task to obtain photographs and verbal stories of friends and fellow workers, periodicals of the time, laws and decrees. Based on the primary education, the work of Lia Campos shows the relevance of the teaching formation for this level of education and the way as the ones that in it work can lead their conceptions and daily practical tasks. This way, I evidence that the cited teacher promotes, in this State, a series of activities as: survey and systematization of the school net; organization of the administrative stuff of the schools; qualifications and courses of improving for lay professors, as well as implantation of the Law of the Education nº 2.171/1957. Through this analysis I show as this teacher left printed her mark in the Rio Grande do Norte historiography by means of her actions, being therefore remembered for that they had followed her experience in norte-riograndense lands

Ce travail est une reflexion sur les pratiques éducatives dévelloppées par des élèves/professeurs dans le Cours de Formation d Éducateurs de la Campagne, réalisé dans un partenariat entre l Université Fédérale du Pará (UFPA), Le Movimento dos Trabalhadores sem Terra (MST Mouvement des travailleurs sans Terre) et le Programme National d Éducation dans la Réforme Agraire (PRONERA), en ayant comme son objectif stratégique rechercher les éléments facilitateurs de l articulation théorie-pratique dans les procédures méthodologique du Cours, fondé sur Paulo Freire. Nous approfondissons des réflexions sur la production d une proposition d Éducation de la Campagne qui, entre autres éléments, se fonde sur la Pédagogie de l Alternance, spécifiquement en ce qui concerne lês catégories Temps École et Temps Communauté. Dans le procès de recherche, nous utilisons comme ressources les documents écrits (dês projets de cours, des rapports, des journaux de la campagne document qui registre le quotidien des activités et des choses réalisées), et les discours des élèves de l Assentamento Palmares II , pendant et après lê Cours. À l analyse, nous identifions comme éléments facilitateurs de la relations théorie et pratique, le Temps École et le Temps Communauté en créant des opportunités, la rélation de ce qui se caracterise comme praxis (action-refléxion-action), en utilisant la recherche comme moyen d insertion dans la réalité et l´existence de groupe (colectif), ce qui a possibilité la participation colective aux réalisations des pratiques pédagogiques plus significatives dans le procès de Formation d Éducateurs de la Campagne, en ayant comme objectif la contribution dans la formation des sujets réalisateurs de leur histoire

Diversidade de afídeos na cultura do algodoeiro no município de Campo Verde (MT)

O objetivo deste trabalho foi verificar a diversidade de afídeos (Hemiptera: Aphididae) na cultura do algodoeiro (Gossypium hirsutum L.) no município de Campo Verde (MT). Os afídeos foram amostrados diretamente nas plantas e através de armadilhas tipo Moericke. As amostragens foram realizadas a cada dois dias, até 60 dias após a germinação das plantas. A espécie Aphis gossypii Glover prevaleceu nas amostragens realizadas sobre as plantas. Formas aladas, de ocorrência acidental na cultura, tais como Aphis spiraecola Patch e Rhopalosiphum padi (Linnaeus) também foram observadas. Com as armadilhas tipo Moericke foram capturados 2280 afídeos alados, pertencentes a 13 espécies: R. padi (52,6% do total), A. spiraecola (26,4%), A. gossypii (8,9%), Rhopalosiphum maidis (Fitch) (5,3%), Geopemphigus floccosus (Moreira) (3,1%), Uroleucon ambrosiae (Thomas) (1,5%), Rhopalosiphum rufiabdominalis (Sasaki) (1,3%), Myzus persicae (Sulzer) (0,4%), Sipha flava (Forbes) (0,3%), Pentalonia nigronervosa Coquerel, Tetraneura nigriabdominalis (Sasaki), Lizerius melanocallis (Quednau) e Toxoptera citricidus (Kirkaldy) (0,1% cada uma). Nas amostragens diretamente sobre as plantas foram observados ápteros e alados de A. gossypii e alados de A. spiraecola e R. padi. Nas armadilhas tipo Moericke, as principais espécies capturadas foram R. padi, A. spiraecola, A. gossypii e R. maidis.
