title: Effect of endodontic sealers on push-out bond strength of CAD-CAM or prefabricated fiber glass posts

description: Abstract This study aimed to evaluate the effect of endodontic sealer (ES) on bond strength (BS) of prefabricated or milled-CAD-CAM (computer-aided design and computer-aided manufacturing) glass-fiber-posts (GFP). Canals of 90 single-rooted teeth were prepared for filling by the single-cone technique with gutta-percha and one of the following ES: AH Plus (epoxy resin), Endofill (zinc-oxide and eugenol), and Bio-C Sealer (calcium-silicate). After post-space preparation, tooth-specimens were equally divided in half according to type of GFP to be used. In the half to receive milled-CAD-CAM posts, tooth specimens were molded with acrylic resin to obtain replicas. These were scanned to enable the laboratory to produce the milled-CAD-CAM GFPs (Fiber CAD Lab, Angelus) by the subtractive technique. The other half of samples received prefabricated GFPs (Exacto, Angelus) (n=15). The GFPs were cemented with dual-cure resin cement (Panavia F2.0, Kuraray). Each root was sectioned into two slices per root region (cervical, middle, apical) that were subjected to the push-out BS test, in a universal testing machine. Failure mode (FM) was classified by scores. The BS data were submitted to generalized linear model analyses, while FM was analyzed using the chi-square test (a=0.05). BS showed no significant difference among the three ES (p &gt; 0.05). BS was significantly higher for prefabricated (mean 10.84 MPa) versus milled-CAD-CAM GFPs (mean 6.94 MPa) (p &lt;0.0001), irrespective of ES. The majority showed mixed failures. It could be concluded that type of ES did not affect BS of GFPs to dentin, and prefabricated-GFPs had higher bond-strength than customized-milled-CAD-CAM GFPs.

title: SCHOOL VOLLEYBALL: CHARACTERIZATION OF THE SCHOOLS/MUNICIPALITIES PARTICIPATING IN THE SANTA CATARINA SCHOOL GAMES

description: ABSTRACT The school environment has contributed to the sports development process, especially due to the diversified offer of activities in Physical Education classes and extracurricular projects focused on sports. The work done with school volleyball teams in the state of Santa Catarina has been highly recognized over the years, but there is little evidence about schools that have contributed to the training of volleyball players in the Santa Catarina scenario. Thus, this study aimed to characterize the schools participating in the Jogos Escolares de Santa Catarina (JESC, Santa Catarina School Games) of volleyball. The documentary analysis of the JESC bulletins provided by the Fundação Catarinense de Esporte (FESPORTE, Santa Catarina Sports Foundation) was carried out. The evidence revealed that the educational establishments with the highest participation and achievements in both categories investigated were basic education schools of the state school system, followed by private educational institutions and, to a lesser extent, municipal schools. While in the women's group, the schools were mostly located in the East-North and South regions, in the men's group, they were concentrated in the Midwest region, especially in small and medium-sized cities with high Human Development Indices (HDIs).

title: SILICA NANOPARTICLES (SiO2NP) USED FOR THE TREATMENT OF DISORDERS ASSOCIATED WITH THE CENTRAL NERVOUS SYSTEM (CNS)

description: In the last decade, nanomedicine has investigated the potential use of silica nanoparticles for drug delivery due to the favorable physicochemical properties of these systems as carriers. Specifically, a few studies have focused on applying silica-based nanosystems to deliver drugs into the central nervous system to treat neurological disorders. The present review aimed to evaluate the properties of silica nanoparticles, such as size, zeta potential, surface area, entrapment efficiency, drug loading, and release profile, exclusively applied for the treatment of central nervous system disorders as well as to describe the correlation between biological outcomes and physicochemical properties. Furthermore, the main processes related to the development of silica nanoparticles, such as preparation and characterization methods, were covered in this review to aid the systematic development of silica-based nanoparticles. In the articles reviewed, silica nanocarriers used in neurological disorders did not exhibit physicochemical similarities. Thus, attempts to prospect relations between physicochemical properties and biological effects are still inefficient when silica nanoparticles are used as drug delivery systems in neurological disorders. Therefore, each silica-based nanocarrier must be fully physicochemical and biologically characterized to comprehend how the structural features of silica nanoparticles affect biological systems.

title: SELF-REFLEXIVE ANTHROPOMORPHISM IN CECE BELL’S AUTOBIOGRAPHICAL COMICS: A STUDY OF THE TRANSGRESSIONS OF NARRATIVE LEVELS

description: Abstract Cece Bell released her autobiographical comic El Deafo (2014) in print and digital versions, transposing herself into the anthropomorphic rabbit Cece, who speaks of her hearing loss experience at four after having contracted meningitis. Young Cece wears a hearing aid on her long rabbit ears, showing her animal, human, and technological hybrid body to others. Nevertheless, she assumes the identity of the superhero “El Deafo,” her alter-ego, to cope with her daily challenges in a community composed mostly of hearing individuals, first as an escape to her imaginary world and later for accepting her identity as deaf. This paper aims to analyse El Deafo as an autobiographical comic, considering the representation of deafness through an unstable hybrid body and a transgression of the narrative levels based on the notion of metalepsis, drawn by Genette, Kukkonen, and Ryan in various media.

title: Brazilian coffee: no to a new international agreement

description: ABSTRACT Four years after the breakdown of the International Coffee Agreement this paper is an attempt to evaluate the position of the Brazilian government. Brazil was, in 1989, the country very much against the renewal of the agreement. To do that an examination was made of the empirical evidence during the last thirty years. Such evidence showed losses in Brazil’s coffee production, exports and market share. In practice, Brazil was the only country to carry the burden of the coffee agreement. The other countries profited at Brazil’s costs. It is also shown the large comparative advantage of coffee production in Brazil and that adjustments should be made in domestic policies.

title: Stable isotopes of oxygen and hydrogen in water: analytical method evaluation and the determination of δ18O and δ2H on a control sample

description: Evaluation studies contribute to the identification of parameters that can affect the accuracy and precision of analytical methods. This study describes the analysis of δ18O and δ2H in water samples by the equilibrium method at the Isotope Geology Laboratory (LGI), Center for studies in Petrology and Geochemistry (CPGq) of the Federal University of Rio Grande do Sul (UFRGS). For that, six batches of analyzes were carried out under different ambient temperature conditions. For the reproducibility tests, four aliquots of the control sample were analyzed at the Polar Climate Center (CPC). Results showed that ambient temperature did not significantly affect the accuracy of the oxygen analysis. However, the mean result at 20 °C showed greater accuracy and acceptable precision. Hydrogen analyzes at a room temperature of 18 °C showed an external standard deviation and an internal precision exceeding the recommended, while at 20 and 22 °C the results were statistically acceptable, being the first more accurate. From that, it is possible to conclude that the determination of δ18O and δ2H in water at the LGI, employing the equilibrium method at an ambient temperature of 20 °C, showed satisfactory repeatability and reproducibility.
