Estrategias felinas: discurso poetico X midia na poesia brasileira contemporanea : Armando Freitas Filho e Sebastião Uchoa Leite
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoA presente dissertação analisa na produção textual de Armando Freitas Filho e Sebastião Uchoa Leite o conflito entre a mídia, como veiculadora de discursos homogeneizantes na sociedade, e o discurso poético como voz alternativa, marcada pela singularidade e pelo exercício crítico em relação às noções de sujeito, subjetividade, verdade, discurso. Para isso, foram estudadas principalmente obras escritas nos anos 1980
Exercise training protects human and rodent β cells against endoplasmic reticulum stress and apoptosis
No full textProlonged exercise has positive metabolic effects in obese or diabetic individuals. These effects are usually ascribed to improvements in insulin sensitivity. We evaluated whether exercise also generates circulating signals that protect human and rodent β cells against endoplasmic reticulum (ER) stress and apoptosis. For this purpose, we obtained serum from humans or mice before and after an 8 wk training period. Exposure of human islets or mouse or rat β cells to human or rodent sera, respectively, obtained from trained individuals reduced cytokine (IL-1β+IFN-γ)- or chemical ER stressor-induced β-cell ER stress and apoptosis, at least in part via activation of the transcription factor STAT3. These findings indicate that exercise training improves human and rodent β-cell survival under diabetogenic conditions and support lifestyle interventions as a protective approach for both type 1 and 2 diabetes.-Paula, F.

Ecotoxicological screening of UV-filters using a battery of marine bioassays
No full textThe present study aimed to assess the toxicity of seven UV-filters: zinc oxide nanoparticles (nZnO, particle size <100 nm), titanium dioxide nanoparticles (nTiO2, primary particle size 21 nm), 2-ethylhexyl-4-methoxycinnamate (EHMC), 4-methylbenzylidene camphor (4-MBC), avobenzone (AVO), octocrylene (OCTO) and benzophenone-3 (BP-3) on three species: Aliivibrio fischeri (inhibition of bioluminescence), Phaeodactylum tricornutum (growth inhibition) and Ficopomatus enigmaticus (larval development success). Results showed nTiO2 to be the most toxic for P. tricornutum (EC50 0.043 mg L−1), while no effect was observed in A. fischeri and F. enigmaticus. EHMC was the most toxic to A. fischeri (EC50 0.868 mg L−1 (15 min) and 1.06 mg L−1 (30 min)) and the second most toxic to P. tricornutum. For F. enigmaticus, the lowest percentages of correct development resulted from 4-MBC exposure, with EC50 of 0.836 mg L−1. Overall, AVO induced low toxicity to every assessed species and OCTO was the least toxic for F. enigmaticus larvae. Considering the results obtained for F. enigmaticus, further larval development assays were performed with nZnO and EHMC under different light (light vs darkness) and temperature (20 and 25 °C) conditions, showing higher percentages of correct development at 25 °C, independently on light/darkness conditions. Under different temperature and photoperiod conditions, nZnO was more toxic than EHMC. Overall, nZnO and EHMC were among the most toxic UV filters tested and, when testing the effects of these UV-filters with temperature the results highlight that the impacts are liable to be lessened at higher temperatures (25 °C compared with 20 °C), in the case of this estuarine polychaete species. Nevertheless, further experiments are necessary to describe the effects of these two UV-filters at different organization levels, to study the toxicity of eventual degradation by-products and to provide more information on the combination of different stressors

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Eficiência de trifloxysulfuron-sodium no controle de Cyperus rotundus L. na cultura da cana-de-açúcar
No full textO objetivo foi avaliar a eficiência de trifloxysulfuron-sodium isolado, em mistura, ou em aplicação sequencial a outros herbicidas no controle de Cyperus rotundus L. na cultura da cana-de-açúcar. O estudo foi realizado em área de produção comercial do cultivar RB 72-454 na Usina Paraíso e em casa de vegetação da Universidade Estadual do Norte Fluminense Darcy Ribeiro, em Campos dos Goytacazes, Rio de Janeiro. As parcelas no campo foram submetidas a nove tratamentos: 2,4-D; trifloxysulfuron-sodium + ametryn; trifloxysulturon-sodium; 2,4-D + 2,4-D (20 dias após a primeira aplicação -DAP); 2,4-D + trifloxysulfuron-sodium + ametryn (20 DAP); 2,4-D + trifloxysulfuron-sodium (20 DAP); halosulfuron (20 DAP) e testemunha com e sem capina. Em casa de vegetação avaliou-se a viabilidade dos bulbos de C. rotundus em função dos tratamentos utilizados no experimento instalado em campo. Os resultados indicaram que o trifloxysulfuron-sodium isolado ou em mistura com ametryn, em aplicação sequencial ao 2,4-D, foi excelente no controle de C. rotundus. Esse herbicida e o halosulfuron, aplicados isoladamente, reduziram a capacidade de reinfestação da espécie daninha em razão da redução de sua propagação e do seu crescimento
Unveiling 'The Scream' by Edvard Munch: Iterative Fuzzy c-Means Analysis of Macro-XRF Mapping
No full text"The Scream" by Edvard Munch belonging to the Munch Museum in Oslo has been analyzed using Macro X-ray Fluorescence (MA-XRF). The non-invasive imaging technique unveiled the elemental distribution of the inorganic materials of the painting and brought to light the artist's palette. The semi-unsupervised classification of MA-XRF datacube through an iterative Fuzzy C-Means (FCM)based analysis was applied to shed light on the complex pigment mixture and execution technique used to create the iconic representation of "The Scream".The analysis revealed the relationship between the main pigments and some other distinctive pigments characterized by low XRF intensities, such as cadmium yellows and oranges. The combination of a well-known investigating technique, such as MA-XRF, with the use of advanced algorithms, provided new informative chemical images representing Munch's painting technique
Influência das condições de Tostagem na Colorimetria de Cotilédones de feijão-caupi (Vigna unguiculata (L.) Walp.).
No full textO feijão-caupi (Vigna unguiculata (L.) Walp.) é uma leguminosa de ampla importância socioeconômica e nutricional, especialmente nas regiões Norte e Nordeste do Brasil, destacando-se por seu alto teor proteico e pela adaptabilidade a condições semiáridas. Considerando sua relevância alimentar e potencial de processamento, o presente estudo avaliou as alterações colorimétricas dos cotilédones submetidos a diferentes condições de tostagem, com variação de temperatura e tempo. O experimento foi conduzido segundo um Delineamento Composto Central Rotacional (DCCR), abrangendo 12 tratamentos, com temperaturas entre 150,5 °C e 249,5 °C e tempos de 5,9 a 34,1 minutos.Na autoria da publicação: Daniel Marcos de Freitas
