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

One of the main activities in the petroleum engineering is to estimate the oil production in the existing oil reserves. The calculation of these reserves is crucial to determine the economical feasibility of your explotation. Currently, the petroleum industry is facing problems to analyze production due to the exponentially increasing amount of data provided by the production facilities. Conventional reservoir modeling techniques like numerical reservoir simulation and visualization were well developed and are available. This work proposes intelligent methods, like artificial neural networks, to predict the oil production and compare the results with the ones obtained by the numerical simulation, method quite a lot used in the practice to realization of the oil production prediction behavior. The artificial neural networks will be used due your learning, adaptation and interpolation capabilities

In the operational context of industrial processes, alarm, by definition, is a warning to the operator that an action with limited time to run is required, while the event is a change of state information, which does not require action by the operator, therefore should not be advertised, and only stored for analysis of maintenance, incidents and used for signaling / monitoring (EEMUA, 2007). However, alarms and events are often confused and improperly configured similarly by developers of automation systems. This practice results in a high amount of pseudo-alarms during the operation of industrial processes. The high number of alarms is a major obstacle to improving operational efficiency, making it difficult to identify problems and increasing the time to respond to abnormalities. The main consequences of this scenario are the increased risk to personal safety, facilities, environment deterioration and loss of production. The aim of this paper is to present a philosophy for setting up a system of supervision and control, developed with the aim of reducing the amount of pseudo-alarms and increase reliability of the information that the system provides. A real case study was conducted in the automation system of the offshore production of hydrocarbons from Petrobras in Rio Grande do Norte, in order to validate the application of this new methodology. The work followed the premises of the tool presented in ISA SP18.2. 2009, called "life cycle alarm . After the implementation of methodology there was a significant reduction in the number of alarms

Ionic liquids (ILs) are organic compounds liquid at room temperature, good electrical conductors, with the potential to form as a means for electrolyte on electrolysis of water, in which the electrodes would not be subjected to such extreme conditions demanding chemistry [1]. This paper describes the synthesis, characterization and study of the feasibility of ionic liquid ionic liquid 1-methyl-3(2,6-(S)-dimethyloct-2-ene)-imidazole tetrafluoroborate (MDI-BF4) as electrolyte to produce hydrogen through electrolysis of water. The MDI-BF4 synthesized was characterized by thermal methods of analysis (Thermogravimetric Analysis - TG and Differential Scanning Calorimetry - DSC), mid-infrared spectroscopy with Fourier transform by method of attenuated total reflectance (FTIR-ATR), nuclear magnetic resonance spectroscopy of hydrogen (NMR 1H) and cyclic voltammetry (CV). Where thermal methods were used to calculate the yield of the synthesis of MDI-BF4 which was 88.84%, characterized infrared spectroscopy functional groups of the compound and the binding B-F 1053 cm-1; the NMR 1H analyzed and compared with literature data defines the structure of MDI-BF4 and the current density achieved by MDI-BF4 in the voltammogram shows that the LI can conduct electrical current indicating that the MDI-BF4 is a good electrolyte, and that their behavior does not change with the increasing concentration of water

The aim of the research is to analyze Direção Espiritual a TV program produced by Catholic Church and presented by Canção Nova Channel. The program is presented by Father Fábio de Melo, a catholic priest that also is a famous religious singer and writer. The analyses included not only some TV programs, but also interviews with some of the viewers and Fabio de Melo himself. The results points out the emergence in Brazil of a new religious speech from Catholic Church founded in comprehension path, dissociated from punishment and guilty. This religious speech is more like a self help speech rather than a tradicional religious discourse itself, very similar to psychotherapeutic speech. The TV program presented by Fabio de Melo is guided in tiny line of sacre and profane which announces contradictions but also a new blend of religious approach in contemporary days

El objetivo de este estudio consistió en capturar y reconstituir el modo por el cual profesoras y profesores vinculados a la educación infantil y a la fase inicial de la enseñanza fundamental producen su identidad docente, en el contexto de una tardía profesionalización. El campo de esa pesquisa envolvió tres instituciones públicas de enseñanza superior, dos en Natal (RN) y una en João Pessoa (PB), que desenvulven programas especiales de formación de docentes vinculados a las respectivas redes locales de enseñanza. Para el atendimiento del objetivo arriba propuesto, fue utilizada la teoría de las representaciones sociales para la captura de los elementos constitutivos de las representaciones sociales del profesorado conforme la formulación de Serge Moscovici y colaboradores, considerándose, aqui, especialmente, la contribución de Abric en su complementar teoría de nucleo central de las representaciones. Teniendo en vista la necesidad de identificación de los elementos estructuradores de las representaciones, y definidores de las identidades en cuestión, se privilegió en la pesquisa la producción discursiva docente y sus condiciones de producción. La utilización de sus evocaciones, bien como de las fuentes escritas por los propios sujetos envolvidos, oportunizó el afloramiento de las diferentes faces constitutivas del ser profesor/a . El corpus decorriente de ese estudio fue entonces somentido a una serie de diferentes métodos / técnicas condensadas en programas informatizados y otros manuales en um esfuerzo para conferir un mayor rigor al análisis de los resultados apuntados. Se utilizó, aún, un referencial de análisis del discurso para viabilizar la emergencia de diferentes ângulos de la configuracion de la identidad en foco. Los resultados apuntam para un significativo deslocamiento de las representaciones docentes, bien como permitem afirmar la hipótesis, inicialmente puesta, de que la profesionalización docente ocurre no apenas de manera tardía, como también viene provocando una resignificación de los referentes de identidad de esos profesionales

Body and writing: Lines and between-lines of production of knowledge in the classroom it is an ethnographic research, longitudinal character, based on experience while experienced educator of the Escola Municipal Professor Amadeu Araújo, located in the city of Natal-RN, from which are made reflections about texts written by students who have distorted age/education level, in the process of literacy. Here as initial goal: to discuss the production of students writing as a process body, considering the record of experiences and the impressions they have made during the teaching process. We initially by a conception of phenomenological body, by understanding it in its complexity, a phenomenon that is made from its relationship with the world and with the Other. The records examined were produced between the year 2000 and 2005 involving writings of 106 students, constituting a universe of 136 texts, from which, delimited a corpus of 27 texts. The relevance with respect to the theme and recurrence in which they were detected, were up to elements that allowed a systematization methodology, defining the following units of analysis: Body, written in everyday; body, written and sexuality; body, written and enjoyment poetics; body, writing and other stories. We used the techniques of search, participant observation, based on the actions and interactions body expressed during the experiment and the analysis of documents that consisted of students in the texts and secondary sources, among them, the records of daily class, reports and projects developed, as well as reports of my pedagogical practice, as a researcher inserted in the investigative process. The experience developed, showed a writing school able to express nuances of human complexity, showing that learning is made in the action body, crossed by various forms of language and pointing to the relevance of a pedagogical work able to articulate the dialogue between the written and registrations body of the students, as subjects of learning

Recognizing the plans left by Foucault as legitimate, for those that the struggle to fight against all forms of way of life subjection takes an important role on human being existence, this thesis questions the impacts of body planning on health specialized media on the production of the contemporary subjectivity. Having the Saúde! magazine as this thesis empirical field, it discusses the subjectivity processes centered on the realization of many bodily practices destined to a perfect body self-construction, finding suitable conditions for a narcissistic development of the new ways of social regulation on hypermodern societies. Our central argument, refering to a specific reflection about the body, media and subjectivity, is that the body promoting over the health specialized media makes possible the creation of new existential territories, configuring the healthy body bio-political production by a subjectivity process open to experimenting and to self-invention. Bodily subjectivity process centered on body self-construction, simultaneously generating human subjectivity singularization and massification, evidencing escape routes to build a body health existential perspective. In this thesis we seek to point not only the historically hegemonic forms of being healthy, but mainly the forces that nowadays question these forms, making possible the thought of other ways to live the health of the body, starting from the subjectivity singularization

Objetivou-se com este trabalho avaliar cinco cultivares de melão rendilhado em dois sistemas de cultivo quanto às características produtivas. O experimento foi instalado em casa de vegetação na UNESP-FCAV, em Jaboticabal-SP, de novembro/05 a fevereiro/06. O delineamento experimental utilizado foi de blocos ao acaso, em esquema fatorial 5 x 2, com quatro repetições. Os fatores avaliados foram cinco híbridos de melão rendilhado (Maxim, Bônus nº2, Shinju 200, Fantasy e Louis) e dois sistemas de cultivo (no solo e em substrato a base de fibra da casca de coco). Após a colheita, foram avaliados a produção por planta (kg planta-1); diâmetro transversal (DTF) e longitudinal (DLF) do fruto, em mm; índice de formato do fruto (IFF); diâmetro transversal (DTL) e longitudinal (DLL) do lóculo, em mm; índice de formato do lóculo (IFL); diâmetro de inserção do pedúnculo (DIP), em mm; e espessura do mesocarpo (EM), em mm. Não se verificou interação significativa entre os fatores avaliados. O cultivo em substrato proporcionou maior produtividade por planta em relação ao cultivo no solo (2,51 e 1,52 kg planta-1, respectivamente), tendo a cultivar Fantasy (2,44 kg planta-1) o melhor desempenho entre as cultivares, não diferindo de Louis e Maxim. Para as características DIP, DTL e EM, foram verificados melhores desempenhos em plantas cultivadas em substrato. Para as características DTF, DLF, IFF e DLL não foram encontradas diferenças entre os sistemas de cultivo. Assim, o cultivo em substrato se destacou em relação ao cultivo no solo, tendo a cultivar Fantasy apresentado melhor desempenho comparada a Shinju 200 e Bônus nº2.

O trabalho foi conduzido em casa de vegetação, na UNESP em Jaboticabal (SP), de junho a novembro de 2001, com o objetivo de avaliar a produção do melão (Cucumis melo var. reticulatus), híbrido Bônus nº2, cultivado em sistema hidropônico NFT, em função da concentração de nitrogênio na solução nutritiva (80, 140, 200 e 300 mg L-1) e número de frutos por planta (2, 3, 4 e livre). O delineamento experimental utilizado foi o de blocos ao acaso, em parcelas subdivididas, com seis repetições. Aos 80 dias após o transplantio, foram observados 2, 3, 4 e 5,1 frutos por planta e, posteriormente na colheita, 2, 2,9, 3,0 e 3,4 frutos por planta, respectivamente para os tratamentos com 2, 3, 4 e fixação livre, sendo esta redução atribuída ao abortamento de frutos. Houve redução no peso médio do 1º, 2º e 3º fruto colhido, com o aumento da concentração de nitrogênio. Plantas com o menor número de frutos, apresentaram maior peso médio dos mesmos, porém com menor produção por planta. A maior produção (2.474 g/planta) foi obtida com 80 mg L-1 de nitrogênio na solução nutritiva.

O objetivo deste trabalho foi avaliar cultivares de melão rendilhado produzidas em plantas sob raleio dos frutos. Foram estudadas as cultivares Maxim, Louis, Fantasy, Shinju 200, e Bônus nº2, com as plantas conduzidas com dois e três frutos. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 5x2, com quatro repetições e com as plantas dispostas no espaçamento de 1,0 m entre linhas e 0,5 m entre plantas. O experimento foi realizado em casa de vegetação, utilizando-se fertirrigação e vasos plásticos de 13 L, preenchidos com fibra da casca de coco Golden Mix® Misto 98. As mudas foram produzidas em bandejas de poliestireno expandido de 128 células e quando estavam com a primeira folha definitiva completamente desenvolvida foram transplantadas aos vasos. Foram avaliados o rendilhamento da casca, os diâmetros longitudinal e transversal do fruto, o índice de formato do fruto, os diâmetros longitudinal e transversal do lóculo, o índice de formato do lóculo, a espessura do mesocarpo, a massa média dos frutos e a produção por planta. Não houve interação entre os fatores estudados. Nas condições deste experimento, a condução de dois frutos por planta resultou em maior rendilhamento da casca, maior diâmetro transversal do fruto, maior diâmetro longitudinal do lóculo e maior massa média dos frutos. Porém, as maiores produções por planta foram observadas quando conduzidas com três frutos. Os híbridos Fantasy e Shinju 200 apresentaram as melhores características de frutos e maiores produções.
