Confidências: os ensaios críticos de Kate Chopin

Between 1894 and 1899 Kate Chopin (1850 – 1904), one of the main exponents of American Realism and Feminism, published seven critical essays in newspapers and journals. To this number, it might be added the sketch ―Confidences‖ and the two first entrances of Impressions, her second diary, totalizing nine texts. These texts unveil a refined critical spirit, an outspoken and edge-cutting style in writing, sometimes sarcastically merciless, and an eager reader, all of them aspects that would be put into practice by the Feminist criticism expressed in the author‘s novels and short stories. To introduce and briefly discuss these essays are the main purposes of this paper.

Resistência ao cisalhamento de bráquetes fotopolimerizados com arco de plasma, LED e luz halógena utilizando diferentes tempos

This study evaluated in vitro the shear bond strength of brackets bonded with xenon plasma arc light, light-emitting diode (LED) and conventional halogen light using different curing times. Brackets were bonded to the buccal surface of 60 human maxillary premolars allocated to five groups. In groups 1 and 2, the resin was cured with the plasma arc for three and six seconds (s), respectively; in groups 3 and 4, the LED was used for five and ten s, respectively; and in group 5, the halogen light was used for 40 s. The specimens were stored in water for 24 hours and subjected to a shear force until bracket failure. The debonding pattern was classified according to the adhesive remnant index (ARI). The results were assessed by Anova and the SNK post-hoc test. No differences were detected among groups 2, 4 and 5, which showed higher averages than groups 1 and 3, which were not different between themselves. The ARI scores showed no differences among the three types of light sources in all times tested. Plasma arc and LED lights can be used with shorter curing times, within certain limits, than conventional halogen light for bonding orthodontic brackets, without decreasing bond strength.

Disparos: ensaios sobre fotografia de guerra

Once the choices set involved in the selection of compositional techniques of a photography is mediated by ideological universes, this final project aims to analyze the photographic coverage of the World War II presented in the brazilian publication Revista da Semana during the period in which Brazil was part of the conflict (1942 to 1945). We study the different composition techniques used and the different effects of meaning articulated by these techniques. Thus, our goal is to see how the repetitions are articulated and the translations of meaning in photojournalistic composition from its narrative structure, that is, their way of coded organization. For this, we used the analysis methodology proposed by Umberto Eco on the rhetoric of the image, involving the five levels of photography decomposition (ie iconic levels, iconographic, tropological, topic and enthymematic). We will analyze these images from the perspective of the effects of meaning that the composition techniques to engender glimpse which were woven meanings to this event in that specific space, and which were mediated discourses of Brazilian participation in the conflict

Fracture resistance of simulated immature teeth after different intra-radicular treatments

The aim of this study was to evaluate the fracture resistance of simulated immature teeth after different intra-radicular treatments. Crowns and roots of bovine incisors were cut transversally and removed to simulate immature teeth. Root canal preparation and flaring were performed using a bur in crown-apex and apex-crown direction. The samples were distributed into 5 groups (n=10): Positive control (PoC) - no root canal flaring or filling; Negative control (NeC) - teeth were sectioned and their root canals were flared; Direct anatomical glass fiber post (RaP) - #2 Reforpost main glass fiber post relined with composite resin; Double tapered conical glass fiber posts (ExP) - #3 Exacto glass fiber post; and #2 Reforpost main glass fiber + Reforpin accessory glass fiber posts (RrP). In RaP, ExP and RrP, 4.0-mm apical plugs were done with MTA Angelus. The specimens were embedded in polystyrene resin inside cylinders and the periodontal ligament was simulated with a polyether-based impression material. The specimens were submitted to compressive fracture strength test (0.5 mm/min at 135° relative to the long axis of the tooth) in a servo-hydraulic mechanical testing machine MTS 810. Data were subjected to one-way ANOVA and Dunnett's C or Tukey's tests (α=0.05). The control groups (PoC and NeC) showed lower fracture strength than the experimental groups. NeC presented the lowest resistance and ExP presented the highest resistance among the experimental groups. The flaring procedures produced a detrimental effect on the fracture resistance of the bovine teeth. Glass fiber intra-radicular posts increased significantly the fracture resistance of simulated immature teeth.
