Actualización 2004 del Código anti-dopaje en los deportes
Evangelista M
RETEL : Revista de Toxicología en Línea , 2004,
Abstract: The World Anti-Doping Agency has assumed responsibility for international doping control from the International Olympic Committee. It has revised, reformed and now presented a new World Anti-Doping Code, which became effective in March 2004, before the Olympic Games Athena's 2004. . The World Anti-Doping Code contains the List of Prohibited Substances and Prohibited Methods. Two important differences from the previous list are that caffeine has been removed from the banned list, and that a new category of 'specified substances' which may produce inadvertent positive tests has been added.

Abstract: the aim of this study was to characterize exports of the northeast of rio grande do sul and far west of santa catarina, and investigate their importance for local development. based on analysis of the thematic documentation content, the study revealed that local exporters do not appear among main exporters of santa catarina, but as for rio grande do sul two companies show up. main local exports are concentrated in the furniture sector (43.53% of total). in the northeast of rio grande do sul, agribusiness is prevailing, mainly in the sector of production within the farm boundaries, with a very strong metal-mechanic industry which accounts for 62.89% of regional economy, followed by agroindustry of vegetal oil extraction which represents 13.95%.

Abstract: Este estudo teve como objetivo caracterizar as exporta es do Noroeste gaúcho e extremo-oeste catarinense, investigando qual é sua importancia para o desenvolvimento local. Apoiado na análise de conteúdo da documenta o temática, o estudo revelou que os exportadores locais n o figuram entre os principais exportadores catarinenses, porém no caso gaúcho duas empresas se evidenciam. As principais exporta es locais concentram-se no setor moveleiro (43,53% do total). No Noroeste gaúcho, o agronegócio é preponderante, principalmente no setor antes da porteira com uma indústria metal-mecanica muito forte, representando 62,89% da economia regional, seguida pela agroindústria de extra o de óleo vegetal com 13,95%. Este estudio tuvo como objetivo identificar las exportaciones del noroeste Gaucho“ y oeste de Santa Catarina, investigando su importancia para el desarrollo local. Apoyado por el análisis de contenido de la documentación temática, el estudio reveló que los exportadores locales no se encuentran entre los principales exportadores de Santa Catarina, pero si dos empresas se destacan. Las principales exportaciones se concentran en el sector del mueble local (43,53% del total). En el Noroeste gaucho la agroindustria es preponderante, especialmente en el sector antes de la puerta con una industria metal-mecánica muy fuerte, que representa el 62,89% de la economía regional, seguido por la agroindustria de extracción de aceite vegetal con un 13,95%.

Generalized entropy indices to measure α- and β-diversities of macrophytes
Evangelista, H. B. A.;Thomaz, S. M.;Mendes, R. S.;Evangelista, L. R.;
Brazilian Journal of Physics , 2009, DOI: 10.1590/S0103-97332009000400008
Abstract: a family of entropy indices constructed in the framework of tsallis entropy formalism is used to investigate ecological diversity. it represents a new perspective in ecology because a simple equation can incorporate all aspects of α-diversity, from richness to dominance and can be also related to a measure of species rarity. in addition, a generalized kullback-leibler distance, constructed in the framework of a nonextensive formalism, is recalled and used as a measure of β-diversity between two systems. these tools are applied to data relative to the macrophytes collected from two not far apart arms of itaipu reservoir, in paraná river basin.
Unstable periodic structures in nematic liquid crystals
Sim?es, M.;Palangana, A. J.;Evangelista, L. R.;
Brazilian Journal of Physics , 1998, DOI: 10.1590/S0103-97331998000400010
Abstract: we present a review of our recent progress in the description of the elastic and dynamical properties of the unstable periodic (walls) arising in a nematic liquid crystal sample. the lonberg criterion for the selection of the period of these walls is analyzed. we present a detailed study of the universal character of these walls, which is the basis for a law of corresponding states of these periodic structures. we show the connection of corresponding states with the constant ratio between the miesowicz viscosity coefficients. finally, the collapse of these structures is investigated. we show that it is due to the exponential growth of the fluctuations localized along the lines where the director does not bend at all.
Experimental study on the rheological behaviour of debris flow

Abstract: A model able to describe all the processes involved in a debris flow can be very complex owing to the sudden changing of the material that turns from solid into liquid state. The two phases of the phenomenon are analysed separately referring to soil mechanics procedures with regard to the trigger phase, and to an equivalent fluid for the post-failure phase. The present paper is devoted to show the experimental results carried out to evaluate the behaviour assumed by a pyroclastic-derived soil during the flow. A traditional fluid tool has been utilized: a standard rotational rheometer equipped with two different geometries. The soils tested belong to deposits that cover the slopes of the Campania region, Italy, often affected by debris flows. The influence of solid concentration Cv and grain size distribution was tested: the soils were destructurated, sieved and mixed with water starting from the in situ porosity. All material mixtures showed a non-Newtonian fluid behaviour with a yield stress τy that increases with a solid volumetric concentration and decreases for an increase of sand fraction. The experimental data were fitted with standard model for fluids. A simple relation between Cv and τy was obtained. The yield stress seems to be a key parameter for describing and predicting the post-failure behaviour of debris flows. These results suggest that in the field a small change in solid fraction, due to rainfall, will cause a slight decrease of the static yield stress, readily inducing a rapid flow which will stop only when the dynamic yield stress is reached, namely on a much smoother slope. This can explain the in situ observed post-failure behaviour of debris flows, which are able to flow over very long distances even on smooth slopes.

RETEL : Revista de Toxicología en Línea , 2003,
Abstract: The cocaine' poisoning (CP) in Rosario are frequent by the high offering regional and the capacity to produce symptoms that alarm to the user. Upon analyzing the 46 consultations by CP, attended in the Clemente Alvarez Emergencies' Hospital, (HECA) among January 1990/april2000, tries to confirm statistically, applying the test of chi square, that the cocaine' income to the patients by diverse route of exposure does not influence in their clinical picture. The 93.5% have among 15 and 39 years' old; 73.9% are male; 65.8% of the CP occur among the 22 and 6 hours, and the 70.5% consult later than 4 hours. Cocaine'state/form are dust (45.7%), liquid (21.7%) or in more than one state (30.4%). The routes of exposure are mucosa nasal (43.5%), parenteral (23.9%) and more than 1 route (23.9%). In the 45 symptomatic'patient s prevail the neurological'symptoms (54.4%) and various symptoms (30.5%). It is confirmed that not statistical association are between clinical pictures and the route of exposure (p>0.05). The high frequency of pictures with neurological and cardiovascular'symptoms, converts to the CP in a complex toxicological emergency, that require intensive care units.
