title: Tomographic characterization of edentulous areas before rehabilitation with single implant

description: Abstract Introduction Imaging resources are indispensable to assist the professional dental surgeon in the formulation of the diagnosis and preparation of an adequate treatment plan for the patient, being essential for the successful rehabilitation with dental implants. Objective The purpose of this cross-sectional study was to characterize the edentulous areas of patients who will be rehabilitated with single osseointegrated dental implant in the aesthetic area of the maxilla by means of computerized tomography and correlate parameters of interest. Material and method Fourteen cone beam computerized tomographies were evaluated in a program according to the following parameters: distance from the cementoenamel junction (CEJ) to the bone crest (BC), distance between the BC and distance between the dental crowns of the teeth adjacent to the prosthetic space (PS), bone width and height of PS, thickness of the palate in the region of the second premolars and molars as well as the horizontal and vertical thickness of the soft tissue in the PS region. Result and discussion The results were analyzed by means of descriptive statistics and the Spearman Correlation test. Weak and moderate correlations and no statistically significant differences were found in most comparisons (≤ 0.29 and ≥ 0.30 ≤ 0.49, respectively). Only for the correlation between PS mucosa thickness versus distance between CEJ and BC in the mesial tooth to PS was found significant statistical difference (p = 0.03) and moderate correlation (r = 0.56). Conclusion Cone beam computerized tomography is a viable tool for the maxillofacial region because it allowed the measurement of several parameters of soft and hard tissue of the buccal cavity useful for planning with dental implants, which may increase the predictability of successful rehabilitation treatments.

title: A Retrospective Study on Unfractionated Bovine Heparin Safety in On-Pump Cardiac Surgery

description: Abstract Background: Heparin decreases the risks of thrombotic phenomena in extracorporeal circulation. However, it must present a robust safety profile itself, especially for bleeding. Contamination of porcine heparin demands an alternative source and consequent assessment of safety. Objective: To evaluate the safety of unfractionated bovine heparin during on-pump cardiac surgery. Methods: Descriptive, retrospective study, evaluating medical records from all patients who had on-pump cardiac surgery over four years. We observed the occurrence of bleeding, thrombocytopenia, postoperative vasoplegia, activated clotting time values and any other coagulation phenomena as safety profile parameters. Results: We evaluated 204 medical records reporting the use of unfractionated bovine heparin. 66.18% of the patients presented thrombocytopenia, 1.04% presented bleeding of more than 2000 mL in the first 24 hours of the postoperative period. One patient presented clots in the surgical field. Median activated clotting time was 137 seconds at baseline, 803 seconds after the first dose of heparin and, after protamine, it returns to similar baseline values, that is, 149.5 seconds. Conclusion: Unfractionated bovine heparin did not present unusual adverse effects and can be considered safe for on-pump cardiac surgery.

title: Where do they speak from? Positions about the new IMF contractual proposal for ordering sovereign debt restructurings

description: Resumo O debate sobre Reestruturações da Dívida Soberana (RDS) está no centro da agenda de políticas econômicas globais. Em 2014, o FMI apresentou uma nova proposta contratual –como parte integrante de um conjunto de reformas– para organizar esses processos e permaneceu fora das discussões destinadas a elaborar um mecanismo estatutário dentro da ONU, o que acentuou as divisões existentes neste campo. Ao contrário da maior parte da literatura especializada que analisa os limites e potencialidades desta proposta do FMI em termos abstratos, este artigo faz isso através de um «jogo de posições nas disputas». Esta nova maneira de abordar o debate sobre RDS, que começa explicitando os pressupostos e os interesses desde onde os agentes falam neste campo, possibilita explicar por que existem não só opiniões diferentes, mas diretamente opostas, sobre o mesmo fato social (a nova iniciativa do FMI). Argumenta-se que esta proposta supera os modelos contratuais existentes, mas deixa aberto uma margem de incerteza sobre a correta organização das reestruturações futuras: a profundidade e as implicações de tal incerteza no mercado da dívida soberana assumem significados particularmente diferentes de acordo com a cosmovisão de cada uma das posições abordadas.

title: The Unified Health System (SUS) and the private assistance sector: interpretations and facts

description: ABSTRACT The essay discusses problems to reflect on, identify contradictions, as well as discern and formulate political strategies on the privatization of the health system in Brazil, especially the multiple meanings of the Unified Health System (SUS) and about what is public and what is private. It is observed that the relations between public and private seized only by measures (quantity of units, activities and human and financial resources) are underlying interests and negotiations between agents and their political decisions and difficulties to discern the structural features of an unequal health system and segmented from the political conjunctures that reproduce them. Thirty years after the 1988 Constitution, there have been advances, impasses and setbacks, as well as adjustments in the understanding of the SUS and the private sector.

title: Evaluation of dental needle deformation and fractal analysis

description: Abstract Introduction Needle fracture in dental anesthesia is rare, but its occurrence has serious complications and should be avoided. Objective The objective of this study was to evaluate the deformation of dental needles after the application of compression forces. Material and method Needles of the Dencojet and Septoject XL brands in the 27G and 30G gauges (4 groups) were folded in two opposite directions in a mechanical test machine DL200 - EMIC, based on ISO 7885: 2010. The compressive strength of the needles was measured at each fold. At the end, visual inspection was performed on an EK3ST magnifying glass in a magnification of 40× for analysis of needle integrity. Result 30G needles did not present significant differences between them. The largest gauges (27G) presented differences in the first (p = 0.0001) and in the second folding (p = 0.0016). Septoject XL 27G needles have been shown to be much less flexible, providing higher values of resistance to folding. Seventh percent of the Septoject XL 30G group fractured near the cannon. All samples from the Septoject XL 27G group showed fractures after the second fold. Conclusion All the gingival needles tested presented acceptable behavior, even when submitted to critical situations. Dencojet 27G needles have been shown to be more flexible when folded. All Septoject XL 27G needles fractured after the second fold. It is not advisable to bend the dental needles.

title: Monitoring of Sobradinho landslide (Brasília, Brazil) and a prototype vertical slope by time-lapse interferometry

description: Abstract The application of geophysical monitoring technologies may offer an opportunity to understand the dynamic of slopes in response to factors triggering their instability. In this study, Ambient Noise Interferometry was used as a monitoring approach on a man-made reduced-scale vertical slope and on a natural-scale landslide in Sobradinho (Brazil), under the influence of mechanical stress and rainfall, respectively. For both experiments, we adopted similar data acquisition system and processing workflow. After preprocessing of ambient seismic noise, the time-lapse changes were determined in terms of relative velocity changes using the moving window cross spectral technique. For the vertical slope, terrestrial laser scanning was also performed to detect crack or fissure generation. The prototype experiment results showed a decreasing trend of relative velocity changes and reached a minimum value of -0.6% at the end of the experiment. No change was detected on the digital elevation model that was computed from terrestrial laser scanning images, due to the absence of centimeter scale superficial fissures. At natural scale (Sobradinho landslide), no significant variation in relative velocity changes was detected for the rainy and non-rainy days, mainly because of the inadequate change in the degree of saturation, which was found within a relatively short period of data acquisition.

title: Temperature field of concrete-filled steel tubular columns in fire

description: Abstract The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil construction area, offering constructive and esthetic advantages. The Eurocode 4 (EN 1994-1-2, 2002) and ABNT NBR 14323:2013 show simple methods for the design of the composite columns under fire situations. Nevertheless, these present limitations in their application. In addition, regarding the determination of the temperature field in the cross section, the Eurocode 4 (EN 1994-1-2, 2002) describes a specific procedure for columns with section profile covered with concrete, but it is neglectful about concrete-filled tubular columns. The goal of this paper is to present a simplified procedure to determine the temperature registered in concrete-filled steel columns and apply the procedure to columns with square section tubes. The temperature distribution was determined by simulations using the computer package ABAQUS (Dessault Systemes Simulia Corp. 2013). After the studies, it has been considered that the procedure described in this paper is an effective alternative for the determination of the field's temperature and for the application of the design of the concrete-filled columns under fire conditions.

title: Financial Education for the Elderly in a Low-Income Context

description: This article discusses consumption among Brazilian low-income elderly people and the importance of considering educational interventions designed for this population. The discussion stems from a participant observation research, developed by means of a pedagogical action performed with elderly women, founded on popular educational principles and cultural-historical approach. Results showed that the participants collectively produced financial control strategies and new conceptual constructions of consigned credit mechanisms. Lastly, some principles advocate the generation of educational practices that promote empowering and protagonism among elderly consumers.

title: Wastewater from Fish Farms for Producing Eucalyptus grandis Seedlings

description: ABSTRACT This work aimed to evaluate the development and quality of Eucalyptus grandis seedlings produced with different dosages of wastewater from fish farming. The experiment was arranged in a completely randomized design with five treatments and four replicates. The treatments were fish wastewater (FW); daily nutritional solution (DNS), combinations of 50% DNS + 50% FW; 25% DNS + 75% FW and solution with weekly application (WNS). The best growth and development results of the eucalyptus seedlings were observed for the solutions applied daily and weekly. The 50% DNS + 50% FW combination did not differ from daily and weekly nutritional solutions for Dickson’s quality index. Fertigation only with wastewater from fish farming resulted in lower growth and development of the seedlings, but the use of the combination of 50% FW + 50% DNS enabled the production of seedlings of similar quality to those fertigated with nutritional solutions.

title: Damage by Acromyrmex spp. to an Initial Pinus taeda L. Planting

description: ABSTRACT The objective of this study is to evaluate the damage caused by Acromyrmex heyeri Forel, 1899 and Acromyrmex lobicornis Emery, 1887 to Pinus taeda L. seedlings during the first two months after replanting. The experiment was conducted in the company Bosques del Plata, located in the province of Corrientes, Argentina. The evaluations were carried out at seven, 14, 21, 36, 50 and 65 days after replanting the seedlings, when the number of dead, alive, non-attacked, alive deneedled, and alive deneedled with cuts/damage to the apical bud by leaf-cutting ants was quantified. The results allow us to conclude that A. heyeri and A. lobicornis are responsible for losses to the order of 20.8% of the seedlings in an initial P. taeda stand at 65 days. The damage caused to seedlings by the two leaf-cutting ant species is constant over time, in which A. lobicornis is more voracious than A. heyeri.
