The Impact

Crateras de impacto por meteorito são formações raras no planeta e de extrema importância para o conhecimento da evoluçãogeológica e biológica da Terra por se tratarem de eventos catastróficos que causaram extinções em massa e movimentaram camadasgeológicas. No Brasil sete crateras de impacto estão cientificamente comprovadas, dentre estas, quatro já classificadas como possíveissítios geológicos. A área objeto deste trabalho, o Cerro do Jarau, está localizada no sudoeste do Estado do Rio Grande do Sul, na divisa como Uruguai e insere-se no contexto geológico da Bacia do Paraná. Trata-se de uma feição semicircular de aproximadamente oito quilômetrosde diâmetro, com cristas elevadas, que se diferenciamgeomorfologicamente do Pampa Gaúcho. A região constitui-se num bom exemplo degeossítio no qual o patrimônio geológico pode associar-se ao patrimônio imaterial, entre eles valores culturais e arqueológicos, paraimpulsionar o turismo local com o apoio de estratégias de geoconservação e um plano geoturístico.Palavras chave: Crateras de Impacto, Geoconservação, Geoturismo, Patrimônio Geológico. ABSTRACT THE IMPACT CRATER OF CERRO DO JARAU, BRAZIL: A GEOTURISTIC APPROACH.Meteorite impact craters are rare formations onthe planet and of utmost importance for the understanding of the biological and geological evolution of the Earth because they areregisters of catastrophic events that caused mass extinctions and geological movements. In Brazil seven impact craters are scientificallyproven, among these four already classified as potential geological sites. The area object of this work, Cerro do Jarau, is located southwestof Rio Grande do Sul State, at the limit with Uruguay and is part of the geological context of the Paraná Basin. It is a semicircular featurewith approximately eight miles in diameter, with high ridges, which differ geomorphologicallyof the Pampa Gaúcho. The region constitutesa good example of geosite where geological heritage can join intangible heritage, including archaeological and cultural values, to boostlocal tourism with the support of geoconservation strategies and a geotourism plan.Keywords: Impact craters, geoconservation, geoturism, geological heritage.

Abstract Background The Bagé Cohort Study of Ageing is a population-based cohort study that has recently completed the first follow-up of a representative sample of older adults from Bagé, a city with more than 100,000 inhabitants located in the state of Rio Grande do Sul, Brazil. This is one of the first longitudinal studies to assess the impact of primary health care coverage on health conditions and inequalities. Our aim is to investigate the prevalence, incidence and trends of risk factors, health behaviours, social relationships, non-communicable diseases, geriatric diseases and disorders, hospitalisation, self-perceived health, and all-cause and specific-cause mortality. In addition, we aim to evaluate socioeconomic and health inequalities and the impact of primary health care on the outcomes under study. Methods/design The study covers participants aged 60 or over, selected by probabilistic (representative) sampling of the urban area of the city of Bagé, which is covered by Primary Health Care Services. The baseline examination included 1593 older adults and was conducted from July 2008 to November 2008. After eight to nine years (2016/2017), the first follow-up was conducted from September 2016 to August 2017. All participants underwent an extensive core assessment programme including structured interviews, questionnaires, cognitive testing (baseline and follow-up), physical examinations and anthropometric measurements (follow-up). Results Of the original participants, 1395 (87.6%) were located for follow-up: 757 elderly individuals (47.5%) were re-interviewed, but losses in data transfer occurred for 22. The remaining 638 (40.1%) had died. In addition, we had 81 (5.1%) refusals and 117 (7.3%) losses. Among the 1373 older adults who were followed down, there was a higher proportion of female interviewees (p=0.042) and a higher proportion of male deaths (p=0.001) in 2016/2017. There were no differences in losses and refusals according to gender (p=0.102). There was a difference in average age between the interviewees (68.8 years; SD ±6.5) and non-interviewees (73.2 years; SD ±9.0) (p<0.001). Data are available at the Department of Social Medicine in Federal University of Pelotas, Rio Grande do Sul, Brazil, for any collaboration.

The Impact

Rabies is a zoonotic disease characterized by acute viral encephalitis. It is almost 100% fatal for infected animals. While cases of human rabies have still been registered in Brazil, in the state of Rio Grande do Sul rabies is considered a controlled disease in urban areas. However, the transmission of bovine rabies – which has been largely associated with the Desmodus rotundus bat – is endemic. Additionally, there are estimates that only 10% of rabies cases are reported. Therefore, this study aimed to describe the positivity rates, geographical distribution, and seasonal occurrence of bovine rabies in RS, as well as the sampling practices in rabies surveillance. Using samples submitted for laboratory diagnosis from 2016 to 2019, we conducted a retrospective study of the sample results, positivity rates, and seasonal occurrence of rabies in cattle. Throughout these four years, less than a third of state municipalities sent samples for diagnosis, suggesting that the occurrence of rabies might still be underestimated in non-sampled areas. A higher number of rabies cases were reported in 2019, a year in which the most diagnosed samples and the highest positivity percentages were recorded. However, the case numbers registered between 2016 and 2019 were not significantly different. We found that the summer and autumn months presented statistically different positivity rates. Besides this, we did not find any positive D. rotundus samples, despite the positivity rates for bovine rabies. Active surveillance, especially of bat populations and under-sampled regions, must be strengthened to correctly estimate the impact of rabies.

The Impact

Digital information generates the possibility of a high degree of redundancy in the data available for fitting predictive models used for Digital Soil Mapping (DSM). Among these models, the Decision Tree (DT) technique has been increasingly applied due to its capacity of dealing with large datasets. The purpose of this study was to evaluate the impact of the data volume used to generate the DT models on the quality of soil maps. An area of 889.33 km² was chosen in the Northern region of the State of Rio Grande do Sul. The soil-landscape relationship was obtained from reambulation of the studied area and the alignment of the units in the 1:50,000 scale topographic mapping. Six predictive covariates linked to the factors soil formation, relief and organisms, together with data sets of 1, 3, 5, 10, 15, 20 and 25 % of the total data volume, were used to generate the predictive DT models in the data mining program Waikato Environment for Knowledge Analysis (WEKA). In this study, sample densities below 5 % resulted in models with lower power of capturing the complexity of the spatial distribution of the soil in the study area. The relation between the data volume to be handled and the predictive capacity of the models was best for samples between 5 and 15 %. For the models based on these sample densities, the collected field data indicated an accuracy of predictive mapping close to 70 %.

A pandemia causada pelo coronavírus disparou a possibilidade da crise em diversos segmentos, sobretudo com a adoção do isolamento social, principal ação para o controle da doença infectocontagiosa. O presente estudo justifica-se pela preocupação em relação às tendências do desenvolvimento sustentável no pós-pandemia da COVID-19, no estado do Rio Grande do Sul. A mensuração do grau de sustentabilidade dos municípios segue a tese de que, quanto maior for o grau de sustentabilidade dos municípios, menor o impacto da pandemia, e maiores os recursos para restabelecer o equilíbrio. O objetivo da pesquisa é analisar a distribuição espacial do potencial para a sustentabilidade no pós-pandemia do COVID-19, nos municípios do Rio Grande do Sul, a fim de gerar um mapa de risco sobre os municípios com menor e maior potencial para a sustentabilidade no pós-pandemia. Foi realizada uma análise ecológica, aplicado o instrumento Barômetro da Sustentabilidade, realizada a distribuição e análise espacial, utilizando o cálculo do Índice de Moran. Os resultados apresentam a distribuição e análise espacial do número de casos confirmados, coeficiente de incidência e quantitativo de óbitos pela COVID-19 no Estado. A espacialidade pode explicar o coeficiente de incidência da doença. Foi estimado o potencial para a sustentabilidade e gerado o mapa de risco do potencial para a sustentabilidade, no pós-pandemia do COVID-19, para os municípios do Rio Grande do Sul.   Spatial analysis and distribution of the potential for sustainability in the post-pandemic of COVID-19 in the municipalities of Rio Grande do Sul A B S T R A C TThe pandemic caused by the coronavirus triggered the possibility of the crisis in several segments, especially with the adoption of social isolation, the main action for the control of the infectious disease, therefore, the present study is justified by the concern in relation to the trends of sustainable development in the post-pandemic of COVID-19, in the state of Rio Grande do Sul. Measuring the degree of sustainability of the municipalities follows the thesis that the greater the degree of sustainability of the municipalities, the less the impact of the pandemic, and the greater the resources to restore balance. The objective of the research is to analyze the spatial distribution of the potential for sustainability in the post-pandemic of COVID-19, in the municipalities of Rio Grande do Sul, in order to generate a risk map with less and greater potential for sustainability in the post- pandemic. This study was carried out by means of an ecological analysis and application of the Barometer of sustainability, later the distribution and spatial analysis was carried out by means of the Moran Index. The spatial analysis, performed by calculating the Moran Index, showed significant spatial independence for confirmed cases (I = 0.058; p = 0.024) and deaths (I = 0.032; p = 0.039), and a significant, albeit weak, correlation. for the incidence coefficient (I = 0.234; p = 0.001) of COVID-19. Spatiality does not explain the distribution of cases and deaths. However, when taking into account the population size of the municipalities, in relation to the number of cases, expressed by the incidence coefficient, the spatial aggregation gains merit. The potential for sustainability was estimated and the risk map of the potential for sustainability was generated, in the post-pandemic of COVID-19, for the municipalities of Rio Grande do Sul.Keywords: Moran index; Sustainability Barometer; Sustainability Index; coronavirus; Pandemic.

The Impact

The WRF mesoscale system 4DVAR data assimilation technique have been used with the purpose of evaluating the impact of the meteorological data assimilation on the numeric time prognosis over the Rio Grande do Sul state. It has been done utilizing the surface and altitude data. The consistency analysis has been done evaluating the numerical prognosis exploring the differences between the analysis with and without data assimilation. The produced prognosis results have been compared spatially using the TRMM satellite data as well as the Canguçu radar reflectivity data. The accumulated rainfall has been validated and compared spatially with the TRMM data for the time period of 12 hours comprehended between October 29th and 30th of 2014. It was possible to realize that as well as the WRF, the WRFVAR overestimated the rainfall values. The radar reflectivity field without data assimilation for October 30th at 06:00UTC detected most accurately the reflectivity centers over the state. On the other hand this field with data assimilation did not present good skill. The temperature field analyses reveal that the 4DVAR assimilation system contributes, one way or another, presenting a little improvement for some points compared to the real data.

<p><strong>Resumo: </strong>Este trabalho tem por objetivo avaliar o impacto da composição do tráfego e das condições de cobrança na capacidade de praças de pedágio. As variações das condições de cobrança de pedágio avaliadas neste estudo incluem reduções nos tempos de atendimento nas cabines manuais, bem como os impactos decorrentes da adoção, e crescente adesão, dos usuários à cobrança eletrônica de pedágio. As informações sobre tempos de atendimento utilizados no estudo correspondem a dados reais coletados em praças de pedágio do estado do Rio Grande do Sul. As análises foram realizadas a partir da simulação de uma praça de pedágio através do software de microssimulação VISSIM. Os resultados evidenciaram e quantificaram o aumento de capacidade das praças associado ao treinamento de arrecadadores e à adoção de tarifas que facilitam o troco. Neste estudo melhorias associadas a estas medidas corresponderam a um aumento de até 19% na capacidade da praça. Melhorias bem mais significativas de desempenho, entretanto, podem ser atingidas com o aumento da adesão dos usuários ao sistema de cobrança eletrônica de pedágio.</p><p><strong>Abstract: </strong>This study aims to assess the impact of the composition of traffic and charging conditions on the capacity of toll plazas. The toll charging conditions evaluated in this study include the reductions in service times at manual toll booths, the introduction of electronic toll collection and the increase in electronic collection compliance rates. Service times adopted in this study correspond to data collected at toll plazas of the state of Rio Grande do Sul. Analyses presented in this paper are based on toll plaza simulations through the microsimulation software VISSIM. The simulation outcomes evidenced and quantified the capacity increase associated with collectors training and the adoption of fares that simplified the change. In this study, improvements associated with these measures corresponded to an increase of up to 19% of the plaza capacity. More significant improvements in performance, however, can be achieved by increasing the compliance of the electronic toll collection system.</p>
