title: Legal Plans, Unusual Interests: Colonial Public Agents and the Project for the Dynamization of Ilhéus’ Economy in the Early 19th Century

description: Abstract the threshold of the 19th century, the village of Ilhéus experienced changes in its economic profile, gradually moving from an economy focused on domestic supply to an export economy. This new regional character was part of a context of economic recovery in Bahia, which happened between the end of the 18th the beginning of the 19th century, when Ilhéus began to invest in sugar, coffee, and cocoa. The project for Ilhéus’ economic dynamization depended, however, on the construction of paths connecting the village to different regions, as well as on the control and use of indigenous labor. In this context, the Ilhéus-Vitória road and the village of Ferradas, located on the southwest axis of this region, imposed themselves as central establishments to the success of public and private projects directed to Ilhéus. This text analyzes the mechanisms used by some colonial public agents in order to carry out the project of economic dynamism destined to Ilhéus in the beginning of the 19th century, likewise, the conciliation elaborated by them between the interests of the State and their own economic interests in that historical situation.

title: AMPLIFICATION AND SELECTION PROFILE OF ISSR MARKERS FOR GENETIC STUDIES IN Calotropis procera

description: ABSTRACT Sodom apple is a plant species adapted to various ecosystems and has stood out for its economic and ecological importance. We evaluated the amplification profile of 23 ISSR primers and selected polymorphic loci for genetic studies of a natural population of Calotropis procera by collecting and extracting genomic DNA from 33 individuals. Genomic DNA was extracted using the sorbitol protocol and 2% CTAB and the ISSR amplification products were resolved by electrophoresis. Based on the amplification profile, the 23 primers were classified as suitable, moderate, and unsuitable. We described the quality of primers considering the total number of bands, mean bands per primer, percentage of polymorphism, Nei’s genetic diversity (expected heterozygosity – He), assuming Hardy-Weinberg equilibrium and the polymorphic information content (PIC). All ISSR primers showed an amplification profile, which generated 173 bands with an average of 7.5 loci per primer. However, only 18 out of the 23 tested primers allowed visible and high-quality amplification, which were classified as suitable and polymorphic. We also observed a mean of 0.30 and 0.24 for PIC and He estimates, respectively. The DiCA3`RG, TriAGA3`RC, and TriCGC3`RC primers were highly transferable to C. procera (they presented quality for amplification with good reproducibility), with PIC values higher than 0.40, He higher than 0.30, and polymorphism higher than 86%.

title: SORPTION, DESORPTION, HALF-LIFE AND LEACHING OF SULFOMETURON-METHYL IN DIFFERENT SOIL CLASSES

description: ABSTRACT Understanding the behaviour of herbicides in the soil can contribute to adapting the correct dose for efficient weed control with less environmental impact. In this study, we sought to evaluate the factors involved in the sorption, desorption, half-life and leaching processes of sulfometuron-methyl in three soil classes: Cambissolo Háplico (CX) (Inceptisol), Latossolo Vermelho (LV) (Oxisol) and Neossolo Quartzarênico (RQ) (Entisol). The sorption and desorption tests were performed using the “batch equilibrium" method. The studies of degradation and formation of metabolites were estimated from the half-life at the end of 180 days. Leaching potential was estimated by testing PVC columns filled with soil. Analyses were performed by ultra-performance liquid chromatography coupled to a mass spectrometer for herbicide quantification. The higher sorption of sulfometuron-methyl in LV (2.81) is related to the low pH (4.7) and mineralogical composition, mainly due to the higher concentration of Fe and Al oxides in this soil, influencing the lower desorption of the herbicide in LV (0.59). This result contributed to more remarkable herbicide persistence in this soil, reducing the molecules available in the solution for degradation. These results contributed to the longer half-life (19 days) in LV compared to the other soils. Among the studied soils, RQ had the highest risk of transport of sulfometuron-methyl based on the GUS Index (2.2) due to its greater desorption (0.34). The results showed that the studied processes are dependent on the physical, chemical and mineralogical attributes of the different classes of soils.

title: Educational collaboration: a methodological proposal for teaching and research based on pedagogical robotics, genetic epistemology and liberating education

description: Abstract: This paper discusses different meanings of collaboration and cooperation based on Piagetian and Freirean concepts among others. We also present a proposal for resignification of these terms in education, which resulted in two processes: educational collaboration and educational cooperation. By combining educational collaboration with pedagogical robotics, university students and a professor started with the context of civil construction to design a robot that was able to identify electrochemical corrosion in concrete structures. Two categories emerged from this process (questions and suggestions) and were analyzed in their form and content through a scientific research method proposed in three stages, based on educational collaboration: hierarchical ratio, categorical ratio and subcategorical qualitative analysis. The educational collaboration culminated in collaborative learning and proved to be a contextualized teaching method in which there is active student participation. Collaborative learning was evidenced by joint construction of knowledge to construct the robot, a result of the rebalance between individual and social factors.

title: Impact of the COVID-19 Pandemic on Elective and Emergency Surgical Procedures in a University Hospital

description: ABSTRACT Objective: to assess the impact of the COVID-19 pandemic on abdominal wall hernia repair surgeries and cholecystectomy in a referral center hospital. Methods: a retrospective, observational, cross-sectional study carried out at Hospital Universitário Evangélico Mackenzie (HUEM), in Curitiba, Paraná, Brazil. Data obtained through electronic medical records of patients who underwent cholecystectomy and abdominal wall hernia repair from March to December 2019 and 2020 at HUEM were included. Data were analyzed using Pearsons Chi-Square test and analysis of variance (ANOVA). Results: a total of 743 medical records were analyzed, with a 63.16% drop in the total number of surgeries in 2020. There was a 91.67% increase in the number of ICU admissions in 2020, as well as a 70% increase in average length of stay. A greater number of complications was observed (in 2020, 27% had complications, while in 2019 this figure was 18.8%) and an increase in mortality (in 2019, this rate was 1.3% and in 2020, 6.5%). There were 6 cases of COVID-19 in 2020, so that of these, 5 patients died. Conclusion: during the COVID-19 pandemic, an important reduction in the number of abdominal wall hernia repair surgeries and cholecystectomy was observed. In addition, there was a statistically significant increase in postoperative complications, mortality rate and length of stay in 2020.

title: Taxonomic review of Psalidodon eigenmanniorum (Cope) based on morphometric and meristic analysis and color pattern (Characiformes: Characidae)

description: ABSTRACT The identity of Psalidodon eigenmanniorum (Cope, 1894) and the possibility of constituting more than one species is tested through analyzes of morphometry (19 measurements), meristic characters (14 counts) and the color pattern of 705 specimens from the Tramandaí/Mampituba, from the Patos lagoon and from the lower Uruguay River drainage. Forty specimens were cleared and stained. Morphometric data were used in Principal Component Analysis, Discriminant Analysis, Geometric Morphometry and Discriminant Function. The analysis was carried out considering the sexes separately within each hydrographic system, as well as comparing the populations between the hydrographic systems and finally in the set of systems representing the area of occurrence of the species. No differences were found between the sexes in the analyzed data. The results showed morphological variation that does not support the recognition of possible cryptic species. The variation found in meristic, morphometric and color pattern data justifies the redescription of the species. The species is described to the aforementioned drainages, and the results demonstrate its phenotypic plasticity.

title: Influence of risk factors on the long-term survival of oral rehabilitation with extra-narrow implants: a retrospective study

description: Abstract Objective This study aimed to retrospectively collect clinical data to evaluate the influence of possible risk factors on the long-term success of implant treatment with extra-narrow (2.9 mm diameter) implants in a daily dental practice setting. Methodology Data were collected from records of patients who received at least one extra-narrow implant from 2012 to 2017, regarding implant survival, prosthesis survival, patient characteristics, and implant characteristics. The association between the dependent variables “implant survival”, “prosthesis survival,” and “adverse events” related to patient and implant characteristics was statistically evaluated by chi-square tests. Moreover, implant and prosthesis survival were analyzed by Kaplan-Meier survival curves. Results The sample was constituted of 58 patients (37 women and 21 men) with a mean age of 54.8 years old (SD: 12.5), followed up for up to eight years. In total, 86 extra-narrow implants were placed within this sample. Four implants were lost, resulting in an implant survival rate of 95.3%. A total of 55 prostheses were inserted and only one (1.8%) was lost, resulting in a prosthesis survival rate of 98.2%. The mean implant and prosthesis survival time was, respectively, 7.1 years and 6.3 years, according to the Kaplan-Meier survival analysis. A correlation was found between smoking and implant loss, which makes implant loss eight times more likely to occur in smokers than non-smokers. A significant association was also found between prosthesis loss and previous need of prosthesis repair. However, it was not considered clinically relevant. No association was found between the occurrence of adverse events and later implant or prosthesis loss. Conclusion High implant and prosthesis survival rates were found in the long term for treatment with extra-narrow implants. Moreover, a significant correlation between smoking and implant loss was observed.
