The increase in obesity among women in the lower income bracket in Brazil has been singled out as a priority issue in the field of Public Health today. Concern about future repercussions of obesity in the less privileged groups calls for an in-depth theoretical approach and the energetic definition of public policy for prevention and control of the affliction in these segments. In this respect, the scope of this work is to attempt to pinpoint some analytical categories in the phenomenon of obesity among the underprivileged female population in Brazil. Biological, socioeconomic and cultural factors appear to interact in the dynamics of female obesity in the context of poverty revealing the complexity of this problem. Public policies of job creation, social inclusion and gender equality in the labor market would appear to be more promising ways of tackling obesity in underprivileged females in Brazil.

Micromagnetic simulations have been used to investigate the magnetization reversal in ultrathin Fe/Rh/FeCo trilayer. The influence of parameters like interlayer magnetic couplings, density of spin-current, and applied magnetic fields was studied. The technological interest on this system comes from the possibilities of stabilization of a nonorthogonal configuration of the magnetizations of the Fe and FeCo layers, recently achieved experimentally. The calculations presented in this work show that this particular magnetization configuration reduces the switching time as compared to the case where both layers have perpendicular magnetic anisotropy. The reversal promoted by pure electrical current (via spin-transfer torque), pure static magnetic field, and a combination of field and current were simulated. It has been found the configurations providing the shortest switching time are the ones with the Fe layer easy direction along [1 1 1] or [1 0 1] and with the FeCo layer presenting perpendicular magnetic anisotropy. © 2016 Elsevier B.V.

This paper investigates the viability of using the dynamic Bayesian Network framework as a tool to classify heart beats in long term ECG records. A Decision Support System composed by two layers is considered. The first layer performs the segmentation of each heartbeat available in the ECG record, whereas the second layer classifies the heartbeat as Premature Ventricular Contraction (PVC) or Other. The use of both static and dynamic Bayesian Networks is evaluated through using the records available in the MIT-BIH database, and the results show that the Dynamic one performs better, obtaining 95% of sensitivity and 98% of positive predictivity, showing that to consider the temporal relation among events is a good strategy to increase the certainty about present events.

The genus Plesiophrictus is diagnosed and redescribed based on type material and additional specimens. The type species P. millardi (Pocock 1899) is redescribed. The genus Heterophrictus is revalidated, with H. milleti as type species. Heterophrictus differs from Plesiophrictus by the absence of serrula on maxillae and by having a rastellum on the chelicerae and stiff, spike-shaped setae on the prolateral coxae I. The significance of characters used in the taxonomy of both genera is discussed. © 2011 The American Arachnological Society.

Type II dentinogenesis imperfecta (DGIII) is an autosomal dominant dental development anomaly that affects both the primary and permanent dentition. This case report describes the clinical, radiographic and morphological characteristics of the teeth of a seven-year-old child with DGI-II determined by optical microscopy and scanning electron microscopy. This consisted of extraction of the primary teeth with periapical lesions due to the advanced state of tooth resorption. Aesthetic restorations were performed on the mandibular anterior teeth and occlusal fissure sealants were applied to erupting teeth. A removable partial upper denture was made in order to return anterior aesthetic function and to aid mastication and speech. FOLLOW UP: The child was examined at 3 month intervals. Over the following 3 years the prosthesis was replaced due to facial growth and fluoride was applied at each follow-up visit to all teeth. The patient remains in follow up and management. Individuals with DGI-II must not neglect their dental health. Early diagnosis, professional advice and treatment with periodic follow-up can help improve the quality of life of such patients.
