    O processo de reinserção social de usuĂĄrios de substĂąncias psicoativas tem se configurado como uma das principais estratĂ©gias da PolĂ­tica Nacional sobre Drogas. Haja vista que o uso de substĂąncias emerge como um dos principais problemas de saĂșde pĂșblica na atualidade, o presente artigo teve como objetivo compreender as percepçÔes dos atores sociais inseridos nas polĂ­ticas da saĂșde, assistĂȘncia social e lideranças comunitĂĄrias acerca do processo de reinserção social dos usuĂĄrios de drogas. Trata-se de uma pesquisa de cunho qualitativo, onde foram realizadas doze entrevistas semiestruturadas com diferentes informantes-chave, inseridos em um territĂłrio com elevados indicadores de uso de drogas. Os resultados apontam para os desafios no processo de inserção efetiva dos usuĂĄrios de drogas em razĂŁo da existĂȘncia de uma rede assistencial multissetorial, um profundo processo de estigmatização social, a naturalização do uso de drogas, a responsabilização da famĂ­lia, alĂ©m da sobrecarga de trabalho nas polĂ­ticas pĂșblicas

    Altimetry for the future: Building on 25 years of progress

    In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and provides guidance for future mission design, research activities, and sustainable operational radar altimetry data exploitation. Recommendations provided are fundamental for optimizing further scientific and operational advances of oceanographic observations by altimetry, including requirements for spatial and temporal resolution of altimetric measurements, their accuracy and continuity. There are also new challenges and new openings mentioned in the paper that are particularly crucial for observations at higher latitudes, for coastal oceanography, for cryospheric studies and for hydrology. The paper starts with a general introduction followed by a section on Earth System Science including Ocean Dynamics, Sea Level, the Coastal Ocean, Hydrology, the Cryosphere and Polar Oceans and the ‘‘Green” Ocean, extending the frontier from biogeochemistry to marine ecology. Applications are described in a subsequent section, which covers Operational Oceanography, Weather, Hurricane Wave and Wind Forecasting, Climate projection. Instruments’ development and satellite missions’ evolutions are described in a fourth section. A fifth section covers the key observations that altimeters provide and their potential complements, from other Earth observation measurements to in situ data. Section 6 identifies the data and methods and provides some accuracy and resolution requirements for the wet tropospheric correction, the orbit and other geodetic requirements, the Mean Sea Surface, Geoid and Mean Dynamic Topography, Calibration and Validation, data accuracy, data access and handling (including the DUACS system). Section 7 brings a transversal view on scales, integration, artificial intelligence, and capacity building (education and training). Section 8 reviews the programmatic issues followed by a conclusion

    Chemical composition fluctuations in roots of Plumbago scandens L. in relation to floral development

    Plumbago scandens L. is a Brazilian tropical/subtropical species that occurs along the coast. Chemically it is mainly represented by naphthoquinones, flavonoids, terpenoids and steroids. The aim of the present work is to study quantitative changes in the root metabolic production of Plumbago scandens during different physiologic developmental stages relative to floration. The results indicated the presence of four substances in the extracts: plumbagin, epi-isoshinanolone, palmitic acid and sitosterol, independent on developmental stage. The naphthoquinone plumbagin has always showed to be the major component of all extracts. Naphthoquinones exhibited their highest content during floration, while the content of the two others components decreased during this stage, revealing an inverse profile. The chemical composition changed depending on the plant requirements.<br>Plumbago scandens L. Ă© uma espĂ©cie brasileira tropical/subtropical que ocorre ao longo da costa.
