Análise de tendências climáticas regionais: temperatura e precipitação no Bioma Pantanal.

Este trabalho analisa o comportamento de variáveis climáticas no Pantanal e caracteriza possíveis mudanças em curso na região. A possibilidade de que mudanças climáticas estejam ocorrendo, em escala global ou regional, exige que investigações empíricas sejam estabelecidas sobre as bases de informações disponíveis, a principal justificativa para este trabalho

Manipulation of Magnetic Skyrmions by Superconducting Vortices in Ferromagnet-Superconductor Heterostructures

Dynamics of magnetic skyrmions in hybrid ferromagnetic films harbors novel physical phenomena and holds promise for technological applications. In this work, we discuss the behavior of magnetic skyrmions when coupled to superconducting vortices in a ferromagnet-superconductor heterostructure. We use numerical simulations and analytic arguments to reveal broader possibilities for manipulating the skyrmion-vortex dynamic correlations in the hybrid system, that are not possible in its separated constituents. We explore the thresholds of particular dynamic phases, and quantify the phase diagram as a function of the relevant material parameters, applied current and induced magnetic torques. Finally, we demonstrate the broad and precise tunability of the skyrmion Hall-angle in presence of vortices, with respect to currents applied to either or both the superconductor and the ferromagnet within the heterostructure

Systemic Bone Mass Alterations and Ligature-Induced Periodontitis in Wistar Rats

Chronic inflammatory conditions have been associated with pathological outcomes, resulting in events responsible for abbreviation of life or decreasing life quality in elders. Periodontal diseases have been associated with systemic disorders, but there is a lack of evidence concerning the relationship between periodontal inflammation and systemic bone conditions. The aim of the present study was to analyze the relationship between ligature-induced periodontitis and generalized bone mass alterations in Wistar rats. Periodontal disease was induced by the placement of silk ligatures around the maxillary left second molar of each animal of the test group (n=14). The control group did not receive ligatures. Systemic bone mass was determined by bone densitometry (double energy X-ray). After 30 and 60 days of ligature placement, bone densitometry analysis did not reveal statistically significant differences between test and control groups both for bone mineral density and bone mineral content (BMC), but at 60 days BMC was slightly lower in the test group. Total bone area was, at 30 days, higher in the test group than in controls. However at 60 days this relationship was inverted, with a higher bone area in the control group. The control group exhibited progressive bone growth, as shown by comparison of BMC between 30 and 60 days; this bone growth was significantly higher than in the test group
