Brasil e brasileiros: notas sobre modelagem de significados políticos na crise do Antigo Regime português na América

Partindo da análise do significado político de Brasil e de brasileiro em documentos escritos por colonos em meados dos setecentos, o artigo aponta para a importância analítica do caráter desviante de variantes americanas da matriz societária portuguesa de tipo Ancien Régime. Trabalhando com os conceitos de memória e experiência, sustenta-se nele a idéia de que, por se tornarem assimétricas, as estruturas nacionais portuguesas dos dois hemisférios também se tornaram irredutíveis a um mesmo enquadramento constitucional quando da instauração da conjuntura revolucionária do final dos anos vinte do século XIX.

A Lagrangian Identification of the Main Sources of Moisture Affecting Northeastern Brazil during Its Pre-Rainy and Rainy Seasons

This work examines the sources of moisture affecting the semi-arid Brazilian Northeast (NEB) during its pre-rainy and rainy season (JFMAM) through a Lagrangian diagnosis method. The FLEXPART model identifies the humidity contributions to the moisture budget over a region through the continuous computation of changes in the specific humidity along back or forward trajectories up to 10 days period. The numerical experiments were done for the period that spans between 2000 and 2004 and results were aggregated on a monthly basis. Results show that besides a minor local recycling component, the vast majority of moisture reaching NEB area is originated in the south Atlantic basin and that the nearby wet Amazon basin bears almost no impact. Moreover, although the maximum precipitation in the ""Poligono das Secas'' region (PS) occurs in March and the maximum precipitation associated with air parcels emanating from the South Atlantic towards PS is observed along January to March, the highest moisture contribution from this oceanic region occurs slightly later (April). A dynamical analysis suggests that the maximum precipitation observed in the PS sector does not coincide with the maximum moisture supply probably due to the combined effect of the Walker and Hadley cells in inhibiting the rising motions over the region in the months following April.

THE SENSIBILITY AND USE OF ENROFLOXACIN IN THE TREATMENT OF FELINE CHRONIC GINGIVITIS

E-mail: alegtd@yahoo.com.br The goal of this study was to evaluate the in vitro sensitivity to enrofloxacin of bacteria isolated from the oral cavity of cats with chronic gingivitis. Twenty five cats male and famale with variable degrees of gingivitis were included in this study. The samples were colected by culturette swabs and submitted to bacterial culture and sensitivity. The results showed that 91% of the bacteria isolated from the culture were sensitive to enrofloxacin, demonstrating that this antibiotic is a good option in the clinical treatment or post-operative treatment of feline chronic gingivitis.
