title: Soil quality indicators for monitoring the short-term effects of mined soil rehabilitation strategies for bauxite

description: ABSTRACT Mining is a significant driver of soil mobilization, which impacts its physical, chemical, and biological properties. Changes in land-use affect the distribution of organic matter fractions in stable aggregates, a process that is still poorly understood, especially in drastically altered areas. Recovering and monitoring soil quality to ensure the sustainable development of agricultural crops in these areas after mining is challenging. This study aimed to evaluate the influence of agronomic practices in soil rehabilitation in a bauxite-mined area after three years of field experiment installations through an assessment of organic properties in soil and aggregate classes; an attempt was also made at proposing and elaborating a Soil Quality Index (SQI), which encompasses the soil’s physical, chemical, and organic properties. Different combinations of fertilization treatments and ground cover plants intercropping with coffee were evaluated as rehabilitation practices. The results showed that after three years of rehabilitation, when organic (OF), chemical (CF), and OF+CF fertilizers were applied to the areas of coffee intercropped with Brachiaria (B), they provided higher C and N contents to the soil and aggregates classes, as well as the compartments of soil organic matter (SOM). The minimum set of soil quality indicators for reclaimed bauxite-mined areas was composed of organic indicators: labile organic carbon (LOC) and mineral-associated organic matter (C-MOM); chemical indicators including pH and effective cation-exchange capacity (t), and physical indicators such as the bulk density (BD) and stable aggregates index in water (SAIW). The t and pH were the variables most sensitive to the management systems implanted during the rehabilitation of the mined area, and, therefore, were considered the best indicators of soil quality. Brachiaria was the cover plant that contributed most to improving the soil quality of mined bauxite areas by increasing the SQI, especially when fertilized. In general, when applied to the Brachiaria, the OF+CF fertilization presented a SQI of 0.78, differing statistically from that of the natural vegetation (1.00). Fertilizers and cover crops in association with coffee in the bauxite-mined areas improved the physical, chemical, and organic properties of the soil, thus representing a viable option for reconditioning mineral exploration areas.

title: Professional trajectory and the impact of education on Fiocruz specialization graduates

description: Abstract This work aimed to analyze graduates’ profiles, education’s effects, and the professional trajectory of those who completed lato sensu courses at Fiocruz. A total of 1,620 graduates participated in 79 courses completed in the 2013-2020 period. A questionnaire was applied before the course and after its completion. A description of the absolute and relative frequency of the variables was realized. A binary logistic regression model was developed to identify variables associated with the positive impact of the course. The odds ratio and its 95% confidence interval were the measures used. Among graduates with a positive impact from the course, those with black/brown skin color are 40% more likely to have a positive impact from the course than those with white skin color; those who have other academic education before the course are 1.5 times more likely than those who have no previous education; those who changed their professional activity as a result of the course are 3.3 more likely than those who were not working; those who reported that the course was closely related to their professional activity were 5.7 more likely than those who reported that the course had poor or no relationship. Every one-year increase since graduation increased the likelihood of the course’s positive impact by 14%.

title: MESOPOROUS SILICA DECORATED WITH SILVER NANOPARTICLES - AN INVESTIGATION OF THE RADIOLYTIC SYNTHESIS PARAMETERS THROUGH FACTORIAL EXPERIMENTS

description: Resistant infectious microorganisms are causing a worldwide emerging problem, called antimicrobial resistance. To avoid this outbreak, new antimicrobial technologies are necessary. Silver nanoparticles (AgNPs) are known for their antibacterial properties and several studies have focused on their synthesis, characterization, and biological assays. One possibility to synthesize AgNPs is through gamma radiation, known as radiolytic synthesis. This work focuses on the radiolytic synthesis of AgNPs capped into a mesoporous silica nanoparticle aiming at an antimicrobial application. The variants of the radiolytic synthesis, which may influence the AgNPs formation, were studied and statistically compared by Design of Experiments Factorial Design in Minitab Software. The Ag content is statically dependent on dose, volume, and pH, as well as on two parameters interaction: [Ag+]-pH and [Ag+]-volume pH interaction. Transmission electron microscopy and nitrogen adsorption analyses indicated the presence of subnanometric AgNPS located inside the mesopores. Silver nanoagglomerates were also found by transmission electron microscopy, which could be formed by silver oxides, as shown in X-ray photoelectron spectroscopy. AgNPs reduce the specific surface area of the silica nanoparticle, while the matrix morphology remains. The nanocomposites presented preliminary biocompatibility observed in in vitro biological assay using fibroblasts, which support their application in biological systems as antimicrobial substitutes.

title: Self-pollination, intra- and interspecific crosses in tomatoes

description: ABSTRACT Tomato genotypes ( Solanum spp.) have genetic variability of most desirable features, such as resistance to biotic and abiotic stresses. However, incompatibility of crosses of wild genotypes with domesticated tomatoes, or even between wild genotypes, hinders the breeding process. Thus, knowledge of the reproductive biology of genotypes and conditions is necessary to maximize the success of artificial crossings. This study evaluated the compatibility of self-pollination, intra- and interspecific controlled crosses, stigma receptivity, and pollen viability in tomato genotypes. We used two commercial genotypes S. lycopersicum (‘RVTM08’ and ‘Redenção’) and seven accessions of wild tomato genotypes (‘AF 26970’, ‘LA-1401’, ‘AF 19684’, ‘LA-1967’, ‘PI-127826’, ‘PI-134417’, and ‘LA-716’). We evaluated all crosses and their reciprocals, besides the self-pollinations. The variables evaluated were fruit index (FI), number of seeds per fruit (SN), and seed germination percentage (GP). Stigma receptivity and grains’ pollen viability index (PVI) were also assessed. The results showed that ‘LA-1967’ was self-incompatible, had a low PVI, and generated fruit without seeds in most crosses. As female parents, ‘RVTM08’, ‘Redenção’, ‘AF 26970’, ‘LA-1401’, and ‘AF 19684’ showed higher FI and SN. There was a wide diversity of reproductive characteristics between the genotypes and crosses that did not influence GP. Compatibility of crosses in tomatoes is determined by the female parent choice and can be affected by stigma receptivity and the PVI.

title: SUSTAINABILITY IN PHOSPHORUS USE: A BIBLIOGRAPHIC REVIEW FOCUSING ON THE CURRENT SITUATION IN THE STATE OF SÃO PAULO, BRAZIL

description: Phosphorus is a non-renewable element essential for the existence of life and also for food security. This resource has the property of limiting plant growth, becoming a fundamental part of agricultural production. On the other hand, when this element is present in high concentrations in aquatic environments, it can start a phenomenon called eutrophication, which causes a series of changes in biological succession processes and strongly negative impacts on species’ biodiversity and wealth. In this context, this work aimed, from an extensive bibliographical review, to gather strategic and essential information related to phosphorus sustainability, provoking a reflection regarding scenarios that involve this indispensable nutrient, focusing on the current situation of the State of São Paulo, Brazil, an important case study, both for the Brazilian and international scenario, by a gathering of data on the current situation of two of the main watersheds in the corresponding region. Relevant technologies used for phosphorus removal in eutrophicated environments are also addressed. Finally, the possibility of reusing the nutrients present in eutrophicated water bodies as an alternative source of phosphate fertilizer for agriculture is demonstrated.

title: SCIENTISTS’ ASSESSMENT: ARE WE USING THE CORRECT METRICS?

description: The use of metrics to evaluate scientists is widespread in the present time, with implications for hiring, fellowships, and research grants. Such fact requires that metrics must be constantly scrutinized to be improved. This work analyzes the use of metrics in the area of chemistry in Brazil and discusses its limitations and shortcomings. The main findings indicate that the use of the impact factor must be complemented by the cited half-life of the journals, and a composite metric named influence factor is proposed, similar to the R-impact. The h-index is not a good metric anymore because does not correct for authorship inflation. The individual h-index (hi), which takes into account fractional counting of citations, is more reliable than the h-index. An analysis on the use of hi-index with randomly selected 15 Brazilian chemists among the top 500 more productive shows an important effect on the ranking order.

title: Interprofessional qualification of prenatal care in the context of primary health care

description: Abstract This study aims to describe and analyze an interprofessional educational intervention for the qualification of prenatal care in the context of primary health care. Method: action-research comprising a prenatal care qualification course with 65 primary health care professionals. Collaborative learning activities were conducted in synchronous and asynchronous meetings. Results: the reflexive thematic analysis of participants’ experiences, views and perceptions on the meanings of the intervention revealed three categories: quality of prenatal care: conceptions and meanings; collaborative learning: strategy to overcome linear and isolated care; the need to evolve from acting locally to thinking globally. Conclusion: the analysis of the interprofessional educational intervention for the qualification of prenatal care in the context of primary health care showed that constructivist, participatory and interprofessional approaches are relevant and pertinent to broaden theoretical perceptions and give new meanings to the work process at different settings of the health network.

title: Effect of axial and rotational restraint on performance of composite beams with fire protection coating

description: Abstract This paper presents the behavior of steel-concrete composite beams with fire protection using the finite element software ABAQUS. An extensive parametric study was carried out to verify the influence of the axial and rotational restraint stiffness, the influence of the spans and the influence of the variation of the fire protection coating, topic with few studies by other authors. The focus of this paper was to verify the axial forces on the supports to study the influence of these forces on the surrounding elements: columns and connections. The study shows that axial and rotational constraints have an important influence on the beams. The values of axial forces are proportionally greater as the beam span is increased. Also verified was that the beam behavior does not change with the variation of the fire protection coating. Finally, the study brings a new approach to the importance of investigating the forces of interaction between beams and columns, as theses forces can lead to unsafe design because the compressive forces in the interaction with the columns and the tensile forces in the catenary phase in connections.

title: The use of dental services in the past year in the brazilian population: a systematic review with meta-analysis

description: Abstract The scope of this study was to analyze the factors associated with the use of dental services in Brazil. The review strategy included PubMed, SciELO, LILACS, BBO, EMBASE, Scopus, WOS and Google Scholar databases, in addition to repositories and databases of dissertations and theses. Studies were selected using the PEO (Population/Exposure/Outcomes) strategy. The outcome of this study was the use of dental services in the last year by the Brazilian population, treated as dichotomous variables for the following analyses: ≤ 1 year and &gt; 1 year. Mantel-Haenszel random effect meta-analysis was performed, estimating Prevalence Ratios (PR) and 95% confidence intervals (95%CI). A total of 94 studies were selected. The majority (98%) had a cross-sectional design, with 63% derived from primary data. For the meta-analysis, 25 studies were included. The use of oral health services in the last year was associated with higher education (≥ 8 years of schooling) (PR = 0.49, (95%CI: 0.39-0.60)); higher family income (≥ 2 minimum wages) (RP = 0.79, (95%CI: 0.74-0.84)); and living in urban areas (RP = 0.79, (95%CI: 0.64-0.97)). The availability of dental services in the Unified Health System needs to be made readily accessible to people with lower income, less education and those living in rural areas.
