Scientific program of the Radioactive Ion Beams Facility in Brasil (RIBRAS)

The RIBRAS facility (Radioactive Ion Beams in Brasil) is installed in connection with the 8MV Pelletron tandem of the University of Sao Paulo Physics Institute. It consists of two superconducting solenoids which focalize light radioactive secondary beams of low energy, produced by transfer reactions. Recent experimental results include the elastic scattering and transfer reactions of (6)He halo nucleus on (9)Be, (27)Al, (51)V and (120)Sn targets. The elastic scattering and transfer of (8)Li and (7)Be on several targets is also being studied. The transfer reaction (8)Li(p,alpha)(5)He of astrophysical interest was also Studied in the E(cm)=0.2-2.5 MeV energy range.

Análisis crítico del libro ¡Vale 6! : Basado en los estilos de aprendizaje de Dunn & Dunn

En la actualidad, las escuelas suecas donde se enseña el español como lengua extranjera tienen la dificultad de que lo que los alumnos aprenden en clase es olvidado con mucha facilidad en corto tiempo. Para que el aprendizaje de los alumnos sea más efectivo, es necesario que estos aprendan esta nueva lengua con la ayuda de ejercicios que estimulen sus sentidos, de tal modo que la enseñanza favorezca a todos los tipos de aprendientes, según la teoría de los estilos de aprendizaje de Dunn & Dunn. El objetivo de este trabajo ha sido el de investigar la presencia de dicha teoría en el libro ¡Vale 6!, si los ejercicios presentes en este libro favorecen a algunos aprendientes más que a otros y qué aprendientes se benefician más con ellos. Para ello se realizó un estudio cuantitativo del contenido del libro. El resultado de este trabajo muestra que solamente ciertos aprendientes (visuales y auditivos) se benefician más con los ejercicios propuestos en ¡Vale6!, lo cual resulta en la necesidad de completar este material con ejercicios adicionales, enfocados en los estilos de aprendizaje rezagados (el kinésico y el táctil), para de este modo poder cumplir con los objetivos planteados por Skolverket.

O imigrante hispano-americano no Brasil : um lugar discursivo afetado pelos deslizes na língua e na história

O desenvolvimento desse trabalho trata da construção discursiva do imigrante hispano-americano no Brasil, principalmente na região sul do país. O marco teórico que orienta esse estudo inclui-se na Análise da Discurso de linha francesa. Destacam-se aspectos importantes do trajeto discursivo que os imigrantes hispano-americanos produziram a partir da década de 60 e que se estende até a década de 90. Grande parte desse período coincide com o aparecimento das ditaduras militares em América Latina, demarcando, assim, um espaço histórico-discursivo específico. Da mesma forma, ressaltam-se implicações desse percurso imigrante quando discutimos a inserção na língua portuguesa, o que exige uma “negociação” com a língua materna espanhol. Podemos identificar esse movimento quando encontramos resistências expostas no âmbito enunciativo. Quando assinalamos esses dois pontos: inserção histórico-discursiva e inserção na língua portuguesa, nos apoiamos em dois conceitos desenvolvidos por Pêcheux em sua teoria discursiva, sendo eles: real da história e real da língua, os quais comportam aspectos de um indecifrável que tanto na história como na língua produzem fendas, que traduzidas enquanto falhas permitem oxigenação e deslocamento de significações. Finalmente e, conforme o quadro aqui exposto, cabe dizer que o fio que orienta nossa pesquisa procura elucidação sobre o processo que o imigrante hispano-americano realiza nesse acontecimento migratório e nele identificar os elementos num discurso que o represente.

Politica de recursos humanos : un estudio comparativo entre Ipiranga y Petrobras Distribuidora

Las Políticas de personal son el punto de partida para la realización de la programación de toda la administración de Recursos Humanos; por su intermedio, se promueve la integración de la empresa con las funciones básicas de Búsqueda, Desenvolvimiento, Manutención, Investigación y Aplicación de personal. Políticas de Recursos Humanos son orientaciones globales emanadas de la realidad que exigen consenso, aI respecto de sus proposiciones y ofrecen ventajas para la empresa, pues su elaboración exige de la comprensión y la aceptación de la organización como un sistema y deI papel moderno de la Administración de Recursos Humanos. El presente trabajo, dentro de este contexto, y particulannente, teniendo en cuenta la naturaleza diferenciada de los objetivos de la empresa privada y la empresa estatal, pretende averiguar de que forma las políticas de las funciones más relevantes de la Administración de Recursos Humanos, como definidos, vienen siendo aplicadas y en que medida son diferentes. Describiendo como las Políticas de Recursos Humanos de cada una de estas funciones vienen siendo aplicadas en las dos empresas en estudio, se busca iden~ficar la esencia de la naturaleza de las distorsiones y comentar las causas que por ventura sean identificadas y formalizar sugestiones que ayuden a mejorar la Administración de Recursos Humanos como un todo. Por lo tanto, se ha querido hacer una comparación en lo que se refiere a las Políticas de Recursos Humanos en la Compafiía Brasilena de Petróleo Ipiranga y Petrobrás Distribuidora, indudablemente, son las empresas más importantes de capital nacional, dedicadas a la distribución de combustibles. Resultado de ésta, se ha encontrado semejanzas y diferencias, algunas provenientes deI grado de autonomía de que disponen, otras, debido a los objetivos distintos que persigen y por las formas particulares de administrar los recursos humanos de cada una de ellas.

Prácticas culturales para el manejo de la Sigatoka negra en bananos y plátanos

Black sigatoka (Mycosphaerella fijiensis) control consists in the continuous use of fungicide sprays and cultural practices. Cultural control reduces inoculum sources of the pathogen and favorable environmental conditions for its development, as well as it increases the vigor of the plants. In order to manage the disease it is necessary to know its behavior through the time, its relationship with the weather and the crop management. The most important cultural practice to reduce the inoculum source is the removal of the whole affected leaves or only the diseased portions of the leaves. The removed tissue is placed over the ground and the use of urea is feasible to accelerate its decomposition. An alternative practice is the "mini-composting" that consists in forming small heaps with the dead leaves and harvested plants for its quick degradation, which allows to reduce the pathogen inoculum and to incorporate nutrients and organic matters into the soil. The early pruning of the tips of the Young leaves before they show symptoms of the disease and the quick elimination of harvested plants reduce the inoculum. Also, the agronomic management of the crop helps to reduce the favorable conditions and to increase the vigor of the plants: this management considers plantation density, drainage systems, irrigation methods, control of weeds, chemical-biological fertilization, and nematode control.

Arranjos urbanos e subjetivos contemporâneos na invenção de territórios turísticos

We seek consistency empirical and analytical rigor to the concept of touristification in the course of the contemporary arrangements of subjectivity and urbanity stations through a landscape of social (dis)encounters between residents and foreigners living in the capital of Rio Grande do Norte, Natal. In the last three decades the city has become a major destination country for national and international tourism, making tourism an important monitor of choreography in search of synchrony between cities and subjectivities, orchestrated by the cyclical crises and the relentless battle for systemic capitalistic expansion and survival. We proceed with an ethnographic and cartographic inspiration in Ponta Negra, where the waterfront redevelopment in 2000 conducted by the government, influenced the implementation of various establishments, services and practices related to the construction of Natal s major industry hub of tourism and entertainment. We proposed an arch-genealogy of touristification inspared on Michel Foucault analytical perspective, increased by authors in confluence or in different theoretical and methodological approaches, among which stand out Karl Marx, Gilles Deleuze and Felix Guattari, Michael Hardt and Antonio Negri. The reflections that initially turned to the advancement of the sphere of consumerism as the issue capable of articulating the developmental trajectory of the capitalist system and the practice of tourism, promoting some effects (un)desirable in the conflictual dynamics of the condition of the district of Ponta Negra, territory each again (re) produces the designs to meet the consumption by affluent portion of the population and foreign, encountering social exclusion and inclusion differentiated a growing trend. We go forward with an analysis of the "liberation of desire" phenomenal features of the process of producing subjective, providing a breakdown of the recent world s financial crisis initially, but proved social and political crisis also, through a plot derived from the operation of real estate speculation, which Natal is mainly caught through touristification, showing the outlines of a generalized crisis in establishing a new order buoyed by the emergence of a context "biopolitical" since it is a major route that uses the capital to survive and expand, while guiding the process of "strategic beautification" held in Ponta Negra, problematized by us. We conclude by assessing the appropriateness of proposing on further analysis to explore the establishment of a "new social ontology in terms of interference touristification ongoing and the constitution of a "new order" local/global, away from that characterize a system's capitalist overcoming, try to give emphasis in the current stage of the radicalization of a capitalistic utopia

Adolescentes e jovens e suas bases de apoio :relações de amizade como suporte social no enfrentamento à violência

The purpose of this work is to map the family and community social supports for adolescents and young students from Bom Pastor Distric, West Zone of Natal/RN, as well as to describe how such resources are used by these individuaIs in that community. Social support refers not only to formal activities or organizations, but also to spontaneous or informal forms of support - friendship and solidarity nets available in the community, affective relations that are meaningful in the lives of children and young people. Our discussion is based on a research performed with 382 adolescents and young students from Jean Mermoz Public School (students from 5th to 11th grades, aged 13 to 14). We emphasized the situations of violence derived from family or community spheres faced by these students. In relation to this specific aspect, we observed the participants more frequently look for help from the informal social supports, mostly from their friends, which indicates that the formal ones are not considered to be effective instruments for social assistance. The search for informal social supports shows the relations informally established in the streets (for instance when they look for help from friends, rei atives or neighbors) have more effect and play an important role in which there are values and affections exchange. Thinking the strengthening of these social links is of extreme importance and leads to the weakening of the hegemonic logics focused on the production of subjects as private identities, and to the amplification of an ethics committed to the disassembly of a sociability anchored to fear, impotence, intolerance, discrimination, and reduction of spaces for circulating and confronting mechanisms of social exclusion. It is crucial that we concentrate our attention to building friendship as a system of reciprocity and affective exchanges, as a space for political actions and production of forms of lives that are potent against social anesthesia

Dependência química em mulheres :um estudo sobre o consumo de medicamentos ansiolíticos no serviço público de saúde de Natal/RN

This work was concerned to investigate the meaning attributed to anxiolytic drugs by women, in public health service. It proposes a joint analysis through a link between three dimensions: the woman, the drug, and public health service itself, in an hegemonic medical assistance model. It is observed that the relation between these elements has a great influence over the use and construction of a particular meaning, by the user. The medication is analysed as a consumption merchandise and as an health symbol. In this way, it reflects a biologized vision, which believes the drug as a solution for all health problems. It tries to analyse the generalized medical prescription for anxiolythics and it s consequences. It focalizes also the production and utilization of public health services by patients, mainly women. The question related to the use of anxiolytics and the meaning construted by women is analysed focusing the way that relations of masculine/feminine gender are organized in our society. At this point of view, it tries to understand the dimension that these questions have in subjectivity production, and how it acts in the health/disease process. Finally, this work tries to understand, in a broad sense, the use of anxiolytics looking at the problem not only as a biological question, but also as a cultural matter. The research was done over seventeen women, all of them anxiolytic users. It was used, as research instrument, semi-structured interview associated with methodological analysis of user s speeches
