To Freud the group of the psychic activity has for purpose the search of pleasure and escape to the displeasure, and of that drift that the aspects associated to memories of unpleasant experiences have for tendency the removal of level of conscience. The unconscious repeats in subject, in way of being and through where he sees the world. That repetition also shows in practice of game. This study leaned on in analysis of Freudian work to play. Because, independent of sphere in that it is acting, the activity of the game is accomplished, predominantly, under an atmosphere predominantly pleased. The game can propitiate situation so that it happens the sublimation of drive forces, making possible occurrence, in an acceptable way socially, contributing to accomplishment of satisfaction. Like this, this study had as objective contemplates, starting from the reading of passages of Freudian work, on desire and the pleasure to play. For the elaboration of that text pertinent bibliographical revision was accomplished to the game, in relationship with psychoanalysis starting from Freud and other authors.

This article discusses the dialogism in Mikhail Bakhtin and the grounds of the linguistic sign in Umberto Eco, with the intention to use the themes and authors, to support the teaching-learning methodologies of foreign language (English and Spanish) at the public school of São Paulo state. The conceptual approach of the two authors allows us to infer that learning a foreign language is effected by the appropriation of utterances and cultural knowledge, pedagogical concept that confronts the traditional method used in the São Paulo school, which is based mainly on grammar teaching and lexicons. The paper derives the theoretical research used to support a dissertation, posing and evaluates preliminary, the integration of traditional theaters in foreign language in public schools, with digital environments (in online courses), and also the educational effects -the use of audiovisual material at the classroom and online learning.

The application technology shows many parameters related to the quality of the application, one is the droplet spectrum, which is influenced by the spray nozzles and the adjuvant used. Therefore, the objective of this work was estimate the behavior of the droplet spectrum generated with different nozzles and different adjuvants. The experiment was installed containing four solutions from different type adjuvant dilution, as vegetal oil, mineral oil, surfactant and drift reduction, which were applied with two nozzle, one pre-orifice flat fan (DG 8003 VS) and other of air induction flat fan (AI 8003 VS), totaling 8 treatments with 3 repetitions. The experiment was realized in ideal weather conditions for spraying. The treatments averages were compared using Confidence Interval at 95% probability and the correlations between variables were analyzed using Pearson at 5% of probability. The analysis of droplet spectrum showed different behavior for each adjuvant and nozzle. The surfactant treatment showed VMD superior for all treatments when sprayed with AI nozzles. For the %vol.<100 µm the lowest value found was for the AI nozzle in combination with the surfactant. The significant correlations found for the nozzles AI and DG were negative between VMD and %vol.<100 µm. It can be concluded that the values of DMV and %vol.<100 µm showed that the nozzle with pre-orifice have droplet spectrum more prone to drift. The surfactant showed to be the best drift reduction technique when combined with the AI nozzle.

This study aimed to verify the influence of adjuvants on the droplet spectrum of an air induction nozzle. The experiment used nine spray solutions, one including only water and eight containing adjuvants: Nimbus® (mineral oil), Óleo vegetal Nortox (vegetal oil), Li-700® (a mixture of lecithin and propionic acid), Agral® (nonyl phenoxy poly ethanol), In-Tec® (nonyl phenol ethoxylate), Antideriva (nonyl phenol ethoxylate), Silwet® L-77 Ag (copolymer polyester and silicon) and TA 35 (sodium lauryl ether sulfate). A flat fan air induction nozzle Hypro® Guardian Air 110 03 was used for the droplet spectrum evaluation. The study was conducted at the Laboratory for Particle Size Analysis (Lapar), at FCAV/UNESP, Jaboticabal/SP - Brazil. The determination of the droplet spectrum characteristics (Volume Median Diameter/VMD, percentage of droplets smaller than 100 micrometers and span) was carried out by a particle size analyzer by laser diffraction Mastersizer S (Malvern Instruments). For statistical analysis the mean values were compared using Confidence Interval at 95% (CI 95%). The results showed that for the Hypro® GA air induction nozzle the oil based adjuvants (Óleo Vegetal Nortox e Nimbus®) increased the VMD. The percentage of droplets smaller than 100 micrometers was lower for the Agral®, Antideriva, In-Tec® e TA 35, in comparison with the Óleo Vegetal Nortox and Li-700®. The span was higher for the oil based adjuvants (Óleo Vegetal Nortox e Nimbus®) and lower for the TA 35 (sodium lauryl ether sulfate), showing that the TA 35 adjuvant has a potential to improve the quality of the droplet spectrum of the Hypro® GA 11003 nozzle.

The aim of this study was to evaluate the influence of fine and medium droplets in the performance of flutriafol and thiophanate methyl + flutriafol for the control of Asian Soybean Rust (Phakopsora pachyrhizi Sydow & Sydow). The experiment was a 2 x 2 factorial design (2 droplet sizes x 2 fungicides) resulting in four treatments with six replications. The experimental area was set up with 24 plots (50 x 21 m). In each plot there was a central assessment area with 10 x 20 m. To the each plot there was a non-treated area placed in opposed direction to the wind. The evaluations of rust control were made by of the calculation of incidence (percentage of plants with rust), severity (level of infection), defoliations and soybean yield. The results were analyzed by the calculation of the confidence interval at 90%. The study was set up in curative control conditions with average infestation of 68.6%, average severity in the lower part of the canopy was of 35.9% and on the upper parte it was 4.57%. The results of severity, defoliation and productivity did not show statistical difference among the treatments. However, it was observed that in general there was tendency of better results with the application of flutriafol alone comparing with thiophanate methyl + flutriafol, since there was a small difference between two commercial products in the flutriafol active ingredient content (62.5 g ha-1 to the flutriafol alone and 60 g ha-1 to the thiophanate methyl + flutriafol). There was no statistical difference between fine and medium droplets. This fact can be explained by the characteristics of systemic action of the flutriafol and by the type of control made (curative). The flutriafol, being a systemic fungicide is less sensitive to the better coverage provided by the smaller droplets and, on the curative control, the amount of product deposited can became more import than coverage, mainly on the superior part of the leaves. These leaves are healthier than the inferior leaves that in general are the first to become completely compromised by the rust, losing importance to the plant. By this reason, medium droplets appear to have offered similar performance even not offering advantages in the leaf coverage. This fact may become important because in the practical side of the use of medium droplets, since this may increase the amount of time to spray, mainly because the fine and very fine droplets have more limitations related to drift and evaporation.

The objective of this study was to assess the hope in the lives of HIV-positive women, using the Herth Hope Scale (HHS). Participants were 111 HIV-positive women who attended a referral outpatient clinic in Fortaleza-CE. From January to May 2009, interviews were held to collect biopsychosocial variables, and the HHS was applied. Data were analyzed using SPSS-8.0 and revealed an average hope index of 34.86, indicating that these women have little hope in life in view of their diagnosis of HIV. The scale item with the highest score was faith. This probably derives from the fact that Aids is incurable, transmissible and generates negative stigma, in addition to its relation with the idea of imminent death. In conclusion, measuring hope among HIV patients through the use of an instrument permits intervention assessment and planning, promoting assistance and motivation to live better and maintain a hopeful attitude.

Analisou-se a distribuição do nervo fibular comum em 30 fetos de equinos, sem raça definida, provenientes do acervo do Laboratório de Anatomia Animal da Faculdade de Medicina Veterinária da Universidade Federal de Uberlândia, que foram injetados e conservados em solução aquosa de formaldeído a 10%. Contatou-se que o referido nervo deriva do isquiático, divide-se em nervos fibulares superficial e profundo, distribuindo-se para os músculos extensores lateral e longo do dedo, fibular terceiro e tibial cranial. Traçando-se uma linha imaginária na região médio-lateral da tuberosidade do osso tíbia, o nervo fibular comum pode ser bloqueado em sua parte proximal, no terço caudal, entre o tendão de inserção do músculo bíceps femoral e a face lateral do músculo gastrocnêmio lateral (terço médio); e o nervo fibular profundo, na parte proximal da tíbia, crânio-distalmente ao fibular comum. O bloqueio do nervo fibular superficial pode ser realizado em duas regiões da tíbia: na proximal, considerando-se a linha imaginária, distalmente ao ponto citado para o fibular comum e caudalmente ao descrito para o fibular profundo; e na distal, na face lateral da articulação tíbio-társica, entre os tendões de inserção dos músculos extensores lateral e longo do dedo.

A aquisição de dados da estrutura termohalina dos oceanos sempre foi limitada pelo alto custo das missões oceanográficas. Sistemas de amostragem in situ menos dispendiosos, como o lançamento de XBTs por navios de oportunidade, a utilização de bóias de deriva, e mais recentemente, de sistemas de observação autõnomos como gliders e flutuadores Argo, foram concebidos como alternativas aos cruzeiros. Estes sistemas são capazes de cobrir vastas porções oceanicas e de fornecer grande quantidade de medições, porem seus dados nem sempre estão disponíveis ou mesmo são adequados `a resolução de um determinado problema ou ao estudo de um fenômeno em questão, devido principalmente à sua falta de sinopticidade e/ou cobertura espacial irregular. Sensores orbitais provaram ser valiosos e comparativamente possuem excelente periodicidade e cobertura espacial, mas suas observações são limitadas apenas à superfície dos oceanos. Assim, a capacidade de se inferir com boa precisão a estrutura termohalina de feições oceanográficas à partir de uma amostragem reduzida e/ou utilizando medições¸ indiretas é desejável e vem sido aprimorada em diversos trabalhos. Métodos clássicos incluem o desenvolvimento de modelos de feição pelo ajuste de curvas paramétricas (e.g. GANGOPADHYAY et al., 1997; CHU et al., 1999) e a reconstrução de perfis utilizando modos EOF (e.g. CARNES et al., 1990; AGARWAL et al., 2007)

Se presenta un modelo estándar de Plan de Manejo de un territorio, con una vocación de destino y un destino de uso de Parque Temático Ambiental, que permite cuantificar logros y blindajes de calidades, en porcentajes. Se entiende por Parque Temático Ambiental un marco geográfico, que rebasa una superficie determinada, con unos límites trazados según criterios geográficos y/o invariantes, y en donde sus contenidos traducen interacciones significativas entre el Hombre y la Naturaleza. El Plan de Manejo se centra en la conservación, rehabilitación, restauración, reconversión y protección de los legados de interés de las interacciones en cuestión, y en el uso de tales activos como recursos de ocio y de aprendizaje sobre el Ambiente (formación y/o educación ambiental). Para desarrollar el Plan de Manejo, se opta, como metodología, el Análisis DAFO Compacto, Cuantitativo y Contrastable y, como herramientas, un árbol genérico de objetivos del Campo de Aplicación de los Parques Temáticos Ambientales (con niveles de diagnóstico de situación, estrategias, metas y fin, y operativo para el lugar con la incorporación de aquellos objetivos de su árbol específico, que no se encontraran ya recogidos en el general), y las matrices de un Marco Lógico de los objetivos involucrados. Se enuncian las Reglas de Aplicación de esta versión de Análisis DAFO Cuantitativo Contrastable: Las Reglas Generales (referentes a los coeficientes de importancia, espaciales, temporales y de probabilidad de presentación). Y las Reglas Procedimentales (en relación con la utilización de los Descriptores de Medición (diseñados y desarrollados con criterios de valoración definidos objetivamente y formulados de forma clara, concisa y universalista). Los resultados obtenidos con la aplicación de todos y cada uno de los Descriptores DAFO a un territorio (respecto al uso del mismo como Parque Temático Ambiental), posibilitan establecer secuencias de calidades óptimas (las que se conseguirían con la mejor de las gestiones), de calidades actuales (de las situaciones imperantes en el momento del Análisis) y de desvíos de calidad (calidades óptimas menos calidades actuales). Estas mediciones: Por una parte, dan los criterios para calificar la vocación de destino y el destino de uso (actual y potencial) de un territorio como Parque Temático Ambiental. Y, por otra, posibilitan calcular los porcentajes de logros que se alcanzarían con las eliminaciones de los desvíos de calidad. Se formula un protocolo de redacción de un Plan de Manejo, conforme con la metodología y herramientas asumidas, y calibrado con su aplicación a un caso real. Las propuestas y los planteamientos (con sus acciones específicas) de los diferentes proyectos del Plan de Manejo, se encuentran estructurados por itinerarios de objetivos (del árbol genérico), y alimentados por los desarrollos de las matrices de un Marco Lógico (de los objetivos involucrados en cada itinerario). El cronograma de actuaciones (en su conjunto y por partes) se deriva también de las temporalizaciones que impone el desarrollo del Marco Lógico. Los logros y las calidades blindadas se obtienen conforme con las correspondencias entre desvíos de calidad, cuantificadas con la DAFO, y actuaciones planificadas. Se verifica la viabilidad de esta forma de redactar Planes de Manejo con ejemplos de casos reales. La metodología y las herramientas empleadas (con las adecuadas modificaciones) son susceptibles de extrapolar a otros campos de aplicación de un territorio (como se ha demostrado).
