title: Metal-Supported Niobium Catalysts Investigation for Conversion of Bio-Renewable Glycerol to Organic Compounds

description: The glycerol oxidative dehydration to organic compounds, especially acrolein and acrylic acid, was studied over vanadium, molybdenum, and cobalt oxides supported on niobium oxide and niobium phosphate catalysts. At 300 °C, the glycerol conversion was 100% over all catalysts tested, and acrolein was the main product observed, without significant deactivation within the time on stream studied. Except for Co/V/Nb2O5, acrylic acid was formed over all catalysts, but the selectivity was not higher than 10%. Acetaldehyde and acetic acid were the other organic oxygenated products formed. Although the catalysts supported over Nb2O5 presented significantly lower acidity than the catalysts supported over NbOPO4, they showed 100% glycerol conversion, indicating that the dehydration of glycerol does not require strong acidity. These data indicate the potential of niobium-based supports in the development of an active and selective catalyst for the glycerol oxidehydration to acrolein and acrylic acid, chemicals of great importance in the industry.

title: Inflammatory Phenotype by OCT Coronary Imaging: Specific Features Among De Novo Lesions, In-Stent Neointima, and In-Stent Neo-Atherosclerosis

description: Abstract Background Coronary stenosis can be caused de novo atherosclerosis, in-stent restenosis, and in-stent neoatherosclerosis, three entities that develop from a diverse pathophysiological milieu. Objective This study aims to investigate, using optical coherence tomography (OCT), whether or not coronary lesions related to these processes differ in their local inflammatory profile. Methods Retrospective analysis of patients with diagnosed or suspected coronary lesions who had undergone OCT imaging for clinical reasons. Macrophage and intra-plaque neovascularization were assessed by OCT and used as surrogates of local inflammation. A significance level of &lt; 0.05 was adopted as statistically significant. Results From the 121 lesions, 74 were de novo, 29 were restenosis, and 18 were neoatherosclerosis. Neovascularization was found in 65.8% of de novo, 10.3% in restenosis, and 94.4% in neoatherosclerosis (p&lt;0.01 for all). The volume of neovascularization was different among lesion types (950 vs. 0 vs. 6220, respectively [median values in 1000 x µm3/mm]; p&lt;0.01 for all), which were significantly higher in neoatherosclerosis and lower in restenosis. The presence of macrophages differed among the lesions (95.9% in de novo vs. 6.9% in restenosis vs. 100% in neoatherosclerosis [p&lt;0.01 for all]). Moreover, the intensity of macrophagic infiltration was different among lesion types (2.5 vs. 0.0 vs. 4.5, respectively [median values of macrophage score]; p&lt;0.01 for all), significantly higher in neoatheroscleosis and lower in restenosis. Conclusion When compared using coronary OCT, de novo atherosclerosis, in-stent restenosis, and neoatherosclerosis presented markedly different inflammatory phenotypes.

title: Different dimensions of oral health literacy are associated with social determinants of health in Brazilian adults

description: Abstract Social determinants of health (SDH) are strongly associated with oral health outcomes, and oral health literacy (OHL) is a potential factor that can modify this association. This study evaluated the association between SDH and OHL, including functional and interactive dimensions of OHL. The cross sectional study was conducted with 354 adults recruited from public dental clinics in southern Brazil. Functional OHL was measured using the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) and the Health Literacy Dental Scale (HeLD-14), for the evaluation of interactional OHL. SDH was evaluated through a structured questionnaire, and economic class was determined based on the Brazilian Economic Classification Criteria. The statistical analysis involved bivariate and multivariate Poisson regression with robust variance (α=0.05) to estimate rate ratios (RR) and 95% confidence intervals (CI). Among the 354 participants, 284 (80.2%) were women and the mean age was 22.9 ± 4.9 years. The median BREALD-30 score was 24 (1st/3rd quintile: 20/27) and the median HeLD-14 score was 45 (1st/3rd quintile: 37/50). Most participants had up to eight years of schooling (71.5%) and belonged to the “C” Economic Class or lower (94.1%). The multiple regression analysis showed that schooling and economic class were associated with the BREALD-30 and HeLD-14 scores, income and age were associated with the HeLD-14 score, and marital status and occupation were associated with the BREALD-30 score. Different dimensions of OHL were associated with SDH in Brazilian adults. This aspect should be incorporated into strategies for improving OHL levels in individuals or populations.

title: Preservation of immunoexpression of type I collagen, BSP and BMP4 in the dentin-pulp complex of head and neck cancer patients after radiotherapy

description: Abstract This study tested the hypothesis that head and neck radiotherapy (HNRT) impacts the immunoexpression of type I collagen, bone sialoprotein (BSP) and bone morphogenetic protein 4 (BMP4), thereby leading to micromorphological changes in the dentin-pulp complex (DPC), and promoting the onset and progression of radiation caries (RC). Twenty-two demineralized sections of carious teeth (a group of 11 irradiated teeth and a control group of 11 non-irradiated teeth) extracted from 19 head and neck cancer patients were analyzed by conventional optical microscopy and immunohistochemistry to investigate the micromorphology (cellular layer hierarchy, blood vessels, odontoblasts, fibroblasts, extracellular matrix, calcification, necrosis, reactionary dentin formation, and chronic inflammation), and the patterns of staining/immunolocalization of type I collagen, BSP and BMP4 in the dental pulp of irradiated and control samples. No significant differences attributable to the direct impact of radiotherapy were detected in DPC micromorphology between the groups. In addition, the patterns of immunohistochemical staining and immunolocalization of the proteins studied did not differ between the irradiated and the control samples for type I collagen, BSP or BMP4. This study rejected the hypothesis that HNRT directly damages dentition by changing the organic components and the microstructure of the DPC, ultimately leading to RC.

title: Row spacing and seed physiological quality of Crotalaria species

description: ABSTRACT Crotalaria crops have important uses, such as in green manuring, nematode control, biological nitrogen fixation and sugarcane reform in Savanna areas. Due to its strategic importance, knowledge about crotalaria seed production technology is a relevant factor to ensure the availability of high physiological quality seeds. This study aimed to assess the effect of two row spacings (20 and 40 cm) on the germination and vigor of Crotalaria ochroleuca and Crotalaria spectabilis seeds produced in two crop seasons (2018 and 2019). The experimental design was randomized blocks, with four replications, in a 2 x 2 factorial scheme (spacing x crop season), for each species. The climatic conditions during seed production significantly infuenced the physiological quality of the crotalaria seeds. The 2018 harvest, with more abundant rainfall and milder temperatures during flowering, provided more vigorous seeds for both species. The 20 cm spacing was more efficient to produce C. ochroleuca seeds with high physiological performance. Notwithstanding, C. spectabilis seeds showed a higher physiological quality when produced under 40 cm spacing than when produced under denser cultivation.

title: THE ACCESS OF THE STUDENT WITH VISUAL IMPAIRMENT TO HIGHER EDUCATION: MICRODATA ANALYSIS OF THE NATIONAL HIGH SCHOOL EXAMINATION

description: ABSTRACT: The Brazilian National High School Examination (called ENEM) is the main instrument of access to Brazilian Higher Education, and its results are also used by public policies for state-subsidized places. Thus, this study aimed to analyze the access to Higher Education of people with visual impairments (PwVi), to investigate factors related to academic performance in the ENEM large-scale assessment, through the analysis of microdata from the 2017 and 2018 editions. Based on the exploratory research methodology, with a quantitative approach, this study investigated the participation, socioeconomic and demographic characteristics, and the performance of PwVi in the exam compared to participants without disabilities, to identify vulnerabilities in the access of the PwVi to Higher Education. The results showed the low participation of PwVi in the exam, in addition to the fact that they have lower family income, older age, less female participation, and less concentration in the South and Southeast regions of Brazil to participants without disabilities. The performance analysis points out that the PwVi had similar results to people without disabilities, thus demystifying the concept of incapacity related to people with disability. However, the results varied according to the severity of the disability, signaling possible accessibility issues in the exam, thus jeopardizing participants with more severe visual impairment. It was concluded that the education policies of access to Higher Education, which use the ENEM score, do not apply to part of this population, excluded from the benefits of Higher Education subsidized by the State.

title: ELECTRICAL PERFORMANCE OF A WATER-COOLED PVT SYSTEM WITH FORCED AND NATURAL CIRCULATION

description: ABSTRACT This study evaluated the electrical performance of a photovoltaic-thermal (PVT) system using water as a cooling fluid (PVT/w), with adaptation, in a photovoltaic module of a device for heating water without direct contact with the cell and with air as the secondary working fluid. The PVT/w system with forced and natural circulation was compared in a regime of thermal accumulation of hot water and supply by a boiler reservoir relative to the same PV panel with the original factory characteristics. The average system temperature, open circuit voltage, current and voltage with load, and generated electric power were analyzed during seven non-consecutive days, with ten repetitions every thirty minutes between 9:30 am and 2:00 pm in the city of Dourados-MS, Brazil, between June and July 2021. The PVT system with forced circulation (PVT/w_CB) presented the best electrical performance compared to the PVT system with natural circulation (PVT/w_SB), in the order of 3.7%.

title: Education and Social Relationships between Museums and Older People: A Scoping Review

description: ABSTRACT Rapidly ageing population increases the demand for activities with learning and social stimulation. Museums are well placed to provide such a function. Objective: How and in what form are museums engaging with older populations. The review will focus on three aspects: (1) Identifying the frameworks and tools being used by and in museums with older people. (2) Assess variables used in research and in areas that supports knowledge creation. (3) Identify evidence in relation to the interactions between museums and older audiences. A review of 8 databases and 2 university repositories (English and Portuguese language). The search retrieved 810 potential sources (2002-2020), 39 sources met the inclusion criteria. They focused on the educational aspects of museums and were produced by disciplines like psychology and gerontology, museology, arts and education. Museums play an important role on health (emphasis on psychological and physical wellbeing), socialization (discussing stereotypes, reducing isolation, redefining social roles), socioeconomic aspects (with local focus on services, partnerships) and on creative aging (promoting non-formal education with lifelong learning at different levels).
