Memória e história em Xosé Lois García: a poética dos vencidos
Authors: Fontoura Sirlei Da Silva , De Almeida Mello Cláudio José
Published: March 2017

A partir dos contextos histórico, político e social em que se inscreve Xosé Lois García, poeta que representa um importante papel na cultura e literatura galegas, o presente trabalho tem como objetivo explicitar de que forma história e memória estão entrelaçadas na sua produção poética para configurar o que identificamos como uma poética dos vencidos. Para tanto, utilizamos pesquisas acerca da memória para compreender em que medida a memória coletiva povo galego é representada pela situação sombria retratada na poesia de Xosé Lois Garcia, com versos que podem ser considerados signos de resistência contra o esquecimento da violência imposta à comunidade galega durante a Guerra Civil Espanhola, e registrada pela historiografia oficial. Trata-se de um trabalho de análise e crítica literária de natureza qualitativa, embasado em material bibliográfico embasado de autores como Halbwachs (2004), Benjamin (1986), Jelin (1998), Torres (2015).
Escrever sem palavras: a escrita ideogrâmica em Clarice Lispector
Authors: Pinho Marília Gabriela Malavolta
Published: March 2017

Propõe-se, com este artigo, que na crônica “Lembrança da feitura de um romance” (1970), Clarice Lispector procura igualar, como ideal de escrita, a palavra ao ideograma, o que faz não por meio de afirmação direta (como o fez na conferência “Literatura de vanguarda no Brasil”), mas por meio de explicações e imagens que aludem às operações do signo ideogrâmico. O método ideogrâmico de composição, tal como este foi explicado e laureado por Ernest Fenollosa e também, posteriormente, por Ezra Pound, contém os argumentos que sustentam tal proposição, ao lado da reunião de evidências do interesse e do conhecimento, por parte de Clarice, seja do ideograma, em si, seja de suas influências na poesia moderna, com o que a escritora teve marcante contato através do grupo intelectual do Professor Francisco Paulo Mendes, quando de sua estadia em Belém do Pará, em 1944.

O corpo (objeto de arte) é um personagem histórico que marcou seu território nos movimentos artísticos. Por esse motivo, tornou-se objeto de pintura, escultura, colagens, com isso, obteve versões plurais de visibilidade e concepções, marcando não apenas os trabalhos de Giotto de Bondone, Leonardo da Vinci, Man Ray, assim como muitos outros artistas tiveram destaque no decorrer do tempo. Na contemporaneidade, destacamos a colagem de Max Martins, que também confere sua abordagem à temática. Assim, este artigo pretende analisar os corpos fraturados: fragmentados, desfigurados, quebrados e deformados na colagem de Max Martins, considerando os aspectos estéticos, simbólicos e intertextuais.PALAVRAS-CHAVE: Max Martins.

“Eu era dois, diversos?” — A fala entre parêntesis revisitada
Authors: De Carvalho Age
Published: March 2017

Conheci Max Martins apresentado por Benedito Nunes, num encontro promovido em sua casa na Travessa da Estrela, em abril de 1980. Max contava 54 anos de idade, eu indo pelos meus 21. Há pouco havíamos dividido o prêmio-publicação da então Secretaria Municipal de Educação e Cultura, a extinta Semec, na categoria Poesia de original literário. O júri não houve por se decidir sobre qual de nossos livros levaria o prêmio — Max concorrendo com O risco subscrito e eu estreando com Arquitetura dos ossos — e assim, consultada a verba disponível, resolveram por bem premiar aos dois. Devo a isso — ao empate no certame, a essa casualidade, portanto — o início da nossa amizade, que duraria até a sua morte, em 2009.
REPENSANDO O PROCESSO DE AVALIAÇÃO NOS & DOS CURSOS DE GRADUAÇÃO EM ADMINISTRAÇÃO
Authors: Igari Camila Olivieri , Viana Adriana Backx Noronha
Published: March 2017

Resumo: O presente artigo apresenta, inicialmente, um panorama da avaliação oficial, ENADE/2012 (Exame Nacional de Desempenho de Estudantes), com destaque para cursos de graduação em Administração, que representam um contingente de 16,7% das matriculas em formações presenciais e 30,22% das formações à distância nas diferentes áreas instrumentais excluindo os cursos de tecnólogos. Considerando as distâncias nos indicadores de qualidade das formações oferecidas, nos quais apenas 6% das graduações foram avaliadas com o Conceito 5 e grande maioria (43%) recebeu o Conceito 3, faz-se, assim, necessárias pesquisas acadêmicas que permitam identificar a relação dos impactos de avaliações institucionais e oficiais para a melhoria do ensino na área. Sugere-se, ainda, a elaboração de uma metodologia de avaliação de cursos num modelo de Framework de Avaliação de Ações Formativas que estabelece um diálogo entre a Avaliação responsiva de Stake (1978, apud. LUDKE,1983) e Metodologia de Avaliação de ações formativas para docentes em quatro níveis proposta Imbernon (2011) como uma adaptação do modelo de avaliação para formação em organizações de Kirkpatrick e Kirkpatrick (2007), definindo-se, assim, um framework delineado pelos níveis: Diagnóstico (Prológo), Reações, Aprendizagens, Transferência e Abrangência. Para cada um dos níveis propostos há uma adaptação de instrumentos de coleta de dados e avaliadores conforme as especificidades de cada instituição formadora. A finalidade da aplicação do framework é oferecer um diagnostico do graduação em Administração considerando um plano de melhorias para a formação de administradores, unificado pelo diálogo e análise conjunta de conteúdos, das aprendizagens, das aplicações e os impactos para a atuação dos futuros administradores na percepção de formadores e formandos ou egressos num processo de avaliação sistêmico e customizado.Palavras-chave: Ensino em Administração.

Published: March 2017

Resumo: O presente artigo objetiva discutir os princípios teóricos da luta do movimento por Uma Educação do Campo como proposta contra hegemônica de educação frente ao Estado capitalista. A análise se deu a partir de uma revisão da literatura a fim de confrontar as premissas deste movimento que defende um projeto educacional que leve em consideração as características e realidades dos sujeitos do campo. Entretanto, são processos conflitantes, uma vez que as políticas educacionais assumem as premissas do Estado capitalista, em que a educação assume a perspectiva de mercadoria. Ainda sim, evidencia-se que apesar das contradições, o movimento tem feito proposições coerentes e conseguido incluir na pauta do governo suas demandas sociais. Porém a materialização nem sempre atende suas perspectivas.Palavras Chaves: Educação do Campo. Estado. Políticas Públicas.

Published: March 2017

Neste trabalho, propõe-se um método de sincronização baseado em um extrator de componentes efetuado por uma versão recursiva do algoritmo de mínimos quadrados. O algoritmo é capaz de separar as contribuições das sequências positiva e negativa das tensões trifásicas nos eixos estacionários. Por meio da escolha adequada do vetor de regressores dos modelos para as tensões valfa\beta(t) o método rejeita qualquer interferência harmônica ou proveniente de desbalanços nas tensões sob análise. Harmônicos de diferentes ordens podem ser eliminados sem atrasos, na mesma estrutura do algoritmo e com o mesmo custo computacional. Para avaliação de desempenho, submeteu-se o método a sinais sintéticos desbalanceados e distorcidos por harmônicos. Além disso, um arranjo experimental foi montado para embarcar a técnica em um processador digital de sinais e testá-la em tensões geradas por uma fonte programável que emula condições de desequilíbrio e de distorções harmônicas. Os resultados demonstraram, além da eficácia, a simplicidade de sua realização.

Published: March 2017

Ropnie przestrzeni zaotrzewnowej to stosunkowo rzadko występujące powikłanie schorzeń różnych narządów jamy brzusznej, najczęściej ostrego zapalenia wyrostka robaczkowego, szczególnie położonego zakątniczo. W pracy przedstawiono przypadek dotychczas zdrowego pacjenta, u którego rozległy ropień powstał w lewej przestrzeni zaotrzewnowej, przebił się do jamy otrzewnowej i prawie przebił się przez skórę w XII przestrzeni międzyżebrowej. Pacjent nie miał objawów brzusznych, tylko skarżył się na umiarkowany ból w lewej okolicy lędźwiowej. Rozpoznanie ustalono na podstawie badania tomografii komputerowej jamy brzusznej, a leczenie operacyjne przez laparotomię, ewakuację i drenaż ropnia było skuteczne, gdyż pacjent wyzdrowiał. Badanie bakteriologiczne ropy z jamy brzusznej wykazało nieliczne kolonie bakterii beztlenowej Fusobacterium species. Przyczyna powstania ropnia pozostała nieustalona.
Screening of The Potential for Different Injection Water Compositions To Alter Wettability to More Water-Wet
Authors: Fjelde Ingebret , Omekeh Aruoture Voke , Haugen Preben Emil
Published: March 2017

The water composition can affect the wettability of oil reservoir sandstone rocks. If several injection water compositions are available, the composition with highest oil recovery potential should be selected. Alteration of wettability to more water-wet conditions has the potential to accelerate the oil production and thereby reduce the water production. The main objective for the presented work was to develop a method for fast screening of the potential for available injection water compositions to alter wettability to more water-wet.

The wettability of reservoir rock samples was characterized by using a flotation method which relies on the affinity of minerals to either the brine or crude oil phase. Crushed reservoir rock samples were aged at reservoir temperature using brine and crude oil of different compositions, and the amounts of oil-wet particles in the oil-phase were determined. The experimental results were compared with geochemical simulation of rock-brine interactions.

In the flotation study, the potential for the injection water compositions to alter the wettability to more water-wet was shown to depend on the crude oil compositions. By geochemical simulations including both ion-exchange and solubility of carbonate minerals, the amounts of divalent cations onto clay surfaces (M2+) were found to vary with the brine composition. Some of the possible injection water compositions were found to reduce M2+ and thereby reduce the potential for cation-bridging. The main trend was decreasing concentration of oil-wet particles (more water-wet conditions) in flotation experiments with decreasing M2+ estimated by simulations. The dominating wetting mechanism for the studied rock-brine-oil systems appeared to be cation-bridging.

The study has shown that screening of the potential for available injection water compositions to alter the wettability to more water-wet can be carried out by combining flotation experiments and geochemical simulations. This screening is much less time consuming than standard experiments, and only small amounts of rock samples are required. The potential for the most promising injection water compositions can then be further evaluated by core flooding experiments.
Water Management Experience in Mature Basin in South Argentina
Authors: Hirschfeldt Clemente Marcelo , Bertomeu Fernando Diego
Published: March 2017

During the oil production in mature fields, the implementation of water flooding projects plays an important role for increasing the oil production and the recovery factor of the reservoirs, and this is the case of the Golfo San Jorge Basin in Patagonia Argentina (GSJB). This basin, located in the central Patagonia (Figure 1), is the oldest productive basin of Argentina where the first economic discovery took place in 1907 in Comodoro Rivadavia. With 13.973 active oil wells (Jun 2016), Golfo San Jorge is the first oil producer basin of Argentina producing 251.000 bpd of oil (49 % of Argentinian oil production) and 3,2 MMbpd of water.

The total of water produced are injected in 3.140 wells used for water flooding projects, where 46% of the oil is produced from this method. The continued implementation of these projects, in company with the drilling of new wells, incorporate water from the reservoirs to the production systems continuously introducing various technical, economic and environmental challenges. As part of a comprehensive water management strategy this paper describe different process and operative considerations, as the result of 109 years of production in the oldest basin of Argentina. The following topics will be addressed: Water production and management in Golfo San Jorge BasinWater treatment and distribution (Surface and subsurface)Water flooding projects trendsWater balance: Bottlenecks AnalysisWater management cost and how affect the total operational costWell integrity managementArtificial Lift challenge's, among othersFigure 1Golfo San Jorge Basin Location

As results it is mentioned the important of to take the decision for manage water during the development of fields. Many challenges arise during the production of a mature field with high volumes of water, but is important to understand about the need not only to do it, but also to have and to apply a field operation model to extend the life of mature fields.

Finally, real statistics, information about facilities, best practices and recommendations, are presented with the objective of provide a guide for developing similar fields.
Student Motivation Profiles: Ukrainian Studies at the Postsecondary Level in Canada
Authors: Nedashkivska Alla , Sivachenko Olena
Published: March 2017

The study investigates postsecondary student motivation and demotivation for studying Ukrainian language, culture, folklore, literature, linguistics, and history. Four groups of students from one Canadian postsecondary institution are studied: (i) students taking Ukrainian language courses; (ii) those in Ukrainian content courses; (iii) students who took a language course at the postsecondary level in the past but did not continue; and (iv) students active in the Ukrainian community who have never taken any Ukrainian studies courses at the postsecondary level but are potentially interested in Ukrainian studies.The analysis is grounded in Dörnyei’s motivational framework, which categorizes L2 motivation into three levels: the language level (in this study, ‘subject area’), the learner level, and the learning situation level (“Motivation”). The subject area level deals with reasons to learn certain subjects: instrumental and integrative motivation. The learner level focuses on learners’ personality traits and cognition. The learning situation level relates to learning environment. Dörnyei’s framework is employed to develop a motivational questionnaire, used as an instrument. The results are analyzed both quantitatively and qualitatively. The quantitative data are elicited through participant responses to close-ended questions, showing the distribution and significance of various motivational factors in different groups of students under study. The qualitative analysis is based on participant responses to open-ended questions, allowing us to analyze both responses and perspectives on how their motivation relates to learning experience and the learning process overall. The combination of the two methods of analysis contributes to a multi-faceted understanding of motivational factors and yields pedagogical implications. The article concludes with a list of recommendations that stem from these analyses.

Published: March 2017

Water contamination with potentially toxic elements (PTEs) has become one of the key issues in recent years that threatens human health and ecological systems. The present study is aimed at removing PTEs like cadmium (Cd), chromium (Cr), copper (Cu) and lead (Pb) from aqueous solutions and industrial wastewater using activated carbon (AC) as an adsorbent through different batch and column experiments. Results demonstrated that the removal of PTEs from aqueous solutions was highly pH dependent, except for Cr, and the maximum removal (>78%) was recorded at pH 6.0. However, maximum Cr removal (82.8%) was observed at pH 3.0. The adsorption reached equilibrium after 60 min with 2 g of adsorbent. Coefficient (R2) values suggested by the Langmuir isotherm model were 0.97, 0.96, 0.93 and 0.95 for Cd, Cr, Cu and Pb, respectively, indicating the fit to this model. In column experiments, the maximum removal of PTEs was observed at an adsorbent bed height of 20 cm with the optimal flow rate of 3.56 mL/min. Furthermore, PTEs removal by AC was observed in the order of Cu > Cd > Pb > Cr. Findings from this study suggest that AC could be used as a promising adsorbent for simultaneously removing several PTEs from wastewaters.

Stem and stump of bananas have potential to be used as an alternative for ruminant feed. However, one of the problem is its rapidly decomposing which affect high of water content. The alternative way to solve this matter by using silage. The aim of this study was to determine the nutritional quality of banana waste silage (stems and stump) with the addition of molasses with different levels. The experimental design was a Completely Randomized Design in factorial 3 × 3 with two replications. The first factor (A) was the composition of the substrate, A1: stump 100% + stem 0%, A2: stump 50% + stem 50%, and A3: stump 0% + stem 100%, while the second factor (B) was the levels of molasses (0; 2.5; and 5%). The parameters measured were dry matter, crude protein, crude fiber, extract ether, ash and BETN. The results showed that the composition of the substrate has significant effect (P<0.05) increased content of dry matter, crude protein, crude fiber, BETN, but did not significant (P>0.05) on extract ether and ash content. There was an interaction (P<0.05) between the substrate composition and the addition of molasses on the content of the ash. The best composition for increasing the nutrient content was stump 100% + stemps 0%. It is conclude that the compostion of stump and stemps may affect the nutrient quality of silage.

The bagasse has potential as an alternative feed for ruminant. However,  though the high of the crude fibre and the very low in the nutritional value make them very limited in using for animal feed. To overcome the problem in order to increase nutritional value was the fermentation technology by the application of the starbio inoculums. The objective of the research was to observe the  nutrition  qualities of the bagasse with aplication of different levels of starbio. The experimental design was  a completely Randomized Design  with 4 treatments i.e. P0 (bagasse + 0% Starbio), P1 (bagasse+ 0.2% starbio), P2 (bagasse+ 0.4% Starbio), P3 (bagasse+ 0.6% Starbio) and each treatment has 5 replication, The parameters measured were pH, dry matter (DM), crude protein (CP), ether extract (EE) crude fiber (CF), ash and Nitrogen Free Extract (NFE). The results of the research indicated that pH of the  fermentation was very good (3.37-3.67), DM (66.59-68.73%), and CP 1.47-1,97%. However, there was no effect on EE, CF, ashes and NFE. The addition of 0.6% starbio was the best result to increase CP but did not affect on ash content.
