title: Laboratory study of tissue repair of resin-based endodontic sealers in critical surgical defects

description: Abstract Filling materials should be restricted to the root canal space. However, sometimes it is impossible to control the apical extrusion, in this case, the fate of the filling material and the result of the treatment will depend on its physicochemical properties and biocompatibility. Objective To evaluate the tissue response and bone repair capacity of endodontic sealers that were implanted in the calvaria of Wistar rats, forming the groups (n=16): AH Plus and Sealer Plus, compared to the clot group. Methodology On days 30 and 60, the animals were euthanized, the calvaria was removed and processed for hematoxylin-eosin, immunohistochemistry for collagen type I, Picrosirus red and microtomographic analysis. Data were subjected to ANOVA and Tuckey tests (p&lt;0.05). Results At 30 days, all groups showed an intense inflammatory reaction (p&gt;0.05). At 60 days, the AH Plus and Sealer Plus maintained an intense inflammatory infiltrate compared to the clot group (p&lt;0.05). We observed immunopositive areas for type I collagen in all groups at 30 days and 60 days (p&gt;0.05). We observed more red collagen fibers for the Sealer Plus compared to the clot group at 30 days (p&lt;0.05). Considering the total fibers, the clot group at 30 days compared to 60 days after surgery showed an increase in the amount of matrix (p&lt;0.05). There were no statistical differences between groups for green and yellow fibers (p&gt;0.05). Regarding morphometric parameters, at 30 days, the newly formed bone volume and number of bone trabeculae were higher in the groups with sealers compared to the clot group (p&lt;0.05). At 60 days, AH Plus and Sealer Plus showed greater bone neoformation compared to the clot group (p&lt;0.05). Conclusions Despite AH Plus and Sealer Plus induced an intense inflammatory reaction, they can be considered biocompatible materials, since they allowed bone repair.

title: The effect of cooling procedures on monomer elution from heat-cured polymethyl methacrylate denture base materials

description: Abstract Objective To evaluate the amount of methyl methacrylate (MMA) released in water from heat-cured polymethyl methacrylate (PMMA) denture base materials subjected to different cooling procedures. Methodology Disk-shaped specimens (Ø:17 mm, h:2 mm) were fabricated from Paladon 65 (PA), ProBase Hot (PB), Stellon QC-20 (QC) and Vertex Rapid Simplified (VE) denture materials using five different cooling procedures (n=3/procedure): A) Bench-cooling for 10 min and then under running water for 15 min; B) Cooling in water-bath until room temperature; C) Cooling under running water for 15 min; D) Bench-cooling, and E) Bench-cooling for 30 min and under running water for 15 min. A, B, D, E procedures were proposed by the manufacturers, while the C was selected as the fastest one. Control specimens (n=3/material) were fabricated using a long polymerization cycle and bench-cooling. After deflasking, the specimens were ground, polished and stored in individual containers with 10 ml of distilled water for seven days (37oC). The amount of water-eluted MMA was measured per container using isocratic ultra-fast liquid chromatography (UFLC). Data were analyzed using Student’s and Welch’s t-test (α=0.05). Results MMA values below the lower quantification limit (LoQ=5.9 ppm) were registered in B, C, E (PA); E (PB) and B, D, E (QC) procedures, whereas values below the detection limit (LoD=1.96 ppm) were registered in A, D (PA); A, B, C, D (PB); C, D, E (VE) and in all specimens of the control group. A, B (VE) and A, C (QC) procedures yielded values ranging from 6.4 to 13.2 ppm with insignificant differences in material and procedure factors (p&gt;0.05). Conclusions The cooling procedures may affect the monomer elution from denture base materials. The Ε procedure may be considered a universal cooling procedure compared to the ones proposed by the manufacturers, with the lowest residual monomer elution in water.

title: In vitro development and acclimatization of Cyrtopodium aliciae L. Linden & Rolfe, an endemic species of the Chapada Diamantina

description: ABSTRACT: Orchids are valued as ornamental plants, bioindicators, and medicinal plants, which implies that some species may be over-collected. Some inhabit very fragile environments and are under threat by the misuse of habitats and anthropogenic impacts. The search for beautiful plants and flowers has increased the number of facilities for micropropagation either by seeding or by cloning plants using in vitro techniques. However, not all species have appropriate media for growth and development that would help in conservation efforts. Cyrtopodium aliciae is an endemic species of rupestrian grassland in Brazil t. It has appeal as an ornamental plant or for use in hybridisation programs dueo its small size and white brownish-purple dotted flowers. This study compared three different media, namely ½ concentration Murashige and Skoog (MS), Vacin and Wendt, and Knudson C, during plant growth and their effect on the acclimatization of Cyrtopodium aliciae. The number and length of shoots and roots, increase in mass, and survival in vitro and ex vitro were analyzed. The experiment was conducted as completely random with a factorial arrangement of treatments (3 × 3) with 10 repetitions per treatment containing 10 plants for the in vitro experiment and 3 repetitions of 10 plants for the ex vitro experiment. Cyrtopodium aliciae performed better in the ½ concentration MS medium with a higher increase in mass, plant development, and survival under both in vitro and ex vitro conditions.

title: An oríkì of my old orixá: the dialogues between science and art in the work of Gilberto Gil

description: Abstract: This article presents the results of research based on Gilberto Gil’s artistic production, highlighting an analysis of the presence of science and technology in his life and work. Part of this investigation was based on his lyrics, biography, books and publications on social networks. We also used a set of elements and information extracted from an interview given by Gilberto Gil online. In addition to the possible dialogues between science and art, we also discuss how science and technology communicate with other fields of knowledge. We make an evaluation of the perception that young people of school age have of the figure of Gilberto Gil in order to verify if the artist is known by the public to which we are directing our work and, finally, we suggest future applications.

title: Economic performance of off-grid photovoltaic systems for irrigation

description: ABSTRACT Renewable energies are alternatives to replace fossil fuels and are crucial for the sustainability of the agricultural sector, besides being an important alternative for pumping water in irrigation. Thus, understanding revenues and expenses is fundamental in economic feasibility. Therefore, the aim of this study was to assess the behavior of economic indicators in off-grid solar energy system for irrigation based on different scenarios. Photovoltaic projects were developed for different irrigation powers ranging from 0.736 to 22.1 kW, and the costs for implementation and operation, as well as the occurrence of economy of scale were evaluated, and the levelized cost of energy for each power analyzed was determined. In addition, sensitivity analyses were performed, considering the variation in product price and investment cost, to demonstrate the responses in relation to economic indicators. Photovoltaic energy projects showed increasing costs with the increase in power, and the normalized cost per kW followed an economy of scale, while the levelized cost of energy showed feasibility, except for the power of 22.1 kW. The sensitivity analyses showed profitability for the analyzed configurations.

title: Soil-structure interaction with time-dependent behaviour of both concrete and soil

description: Abstract As the consideration of soil-structure interaction is increasingly being incorporated into design practice, there is a need for solutions that consider the most relevant aspects of the behaviour of both the concrete and the soil, some of which are time-dependent. The present work introduces a model that suits both the structure and the foundation – including the supporting soil – allowing the coupled analysis of hardening on cure, creep, shrinkage and cracking of concrete, and consolidation of soil. Both the structure and the foundation are modeled as one-dimensional finite elements. The time-dependent behaviour of the concrete and soil is modeled using Kelvin chains. For the structural elements, a mixed finite element formulation is used. Validation tests were conducted in the proposed modeling, comparing its results with available experimental and analytical data. The study of a reinforced concrete continuous beam supported by foundations on consolidating clay considering the time-dependent behaviour of the materials showed considerable changes in the effects of the soil-structure interaction.
