Hazardous elements in urban cemeteries and possible architectural design solutions for a more sustainable environment.

The general objective of this study is to identify the presence of hazardous elements in the soils of five urban cemeteries in the city of Passo Fundo, in southern Brazil, and to design solutions (architecturally) for future cemeteries to be more sustainable by mitigating toxicological risks to the population residing in the area. A total of 250 soil samples were obtained from points within the cemeteries and in areas surrounding the two oldest cemeteries at a distance of up to 400m. Twelve architects who design cemeteries primarily focused on sustainability were interviewed, and presented their suggestions for sustainable urban cemetery design. The Building Information Modeling (BIM) computer modeling system was utilized to present a visual representation of suggested architectural features by these architects. The concentration of Pb in the vicinity of cemeteries deserves special attention, as concentrations of this neurotoxin exceed the federal limits set by Brazil. Soil Pb values were found to exceed the limit of 72mgkg-1 up to a distance of 400m from the walls of cemeteries A and B, indicating the presence of a danger to human health even at greater distances. This manuscript highlights construction features that enable future burial structures to adequately mitigate the very real problem of contaminants entering the environment from current cemetery design. Two-thirds of the technicians interviewed for this manuscript, each of whom specialize in Brazilian cemetery design, highlighted the importance of revitalizing urban vegetation both when constructing and revitalizing urban vertical cemeteries.

THE ROLE OF LOCAL EDUCATION PROGRAMS FOR SUSTAINABLE CITIES

This research aimed to analyze the role of local education programs in Passo Fundo (Brazil) to develop sustainable cities. In this analysis, we sought to describe the management of public policies in the area of education in the city of Passo Fundo; identify the characteristics of a sustainable city present in Passo Fundo; and propose a set of actions in the area of public education for the city of Passo Fundo, in the direction of the concept of sustainable cities. Initially, a theoretical approach was made, starting from articles and books that deal with the subject. A descriptive, exploratory, qualitative research was carried out, with semi-structured interviews with five municipal managers linked to the education area of the chosen city – Passo Fundo. Data were computed, analyzed, and interpreted using content analysis. The results show that the notion and recognition of education and the sustainable city are evidenced, with the importance of citizen participation and education as a formative agent for the effectiveness of sustainable city development. It can be verified concerning management practices in education the practices of events to condition a sustainable city, the International Folklore Festival, the Book Fair, and the Literary Journey.

Prevalence and associated factors of self-reported halitosis among institutionalized adolescents: Cross-sectional study.

To assess the prevalence and associated factors of self-reported halitosis in institutionalized adolescents in a city in southern Brazil. This cross-sectional study involved male institutionalized adolescents, aged 15-19 years old, at the Socio-Educational Assistance Center in the city of Passo Fundo, Brazil. Data collection was performed by a research team composed of two interviewers, two clinical examiners of oral health and two examiners of salivary flow. A structured questionnaire was applied, which included demographical, socioeconomical, general health behaviour, presence of health problems and oral health self-perception variables. Decayed, Missing, Filled Index was used for the clinical examination. The salivary flow collection was performed using the mechanically stimulated total saliva method, in which only the liquid component was measured. The prevalence of self-reported halitosis in this sample was 51.5% (n=35). In the final multivariate analysis, halitosis was significantly associated with the non-white racial group (prevalence ratio [RP]:1.703; 95% confidence interval [95%CI]:1.101-2.634), use of crack (RP:1.857; 95%CI:1.270-2.714) and number of decayed teeth (PR: 1.123; 95%CI:1.008-1.252). The use of alcohol and access to dental care in the last 12months were not significantly associated with self-reported halitosis. It was concluded that non-white and crack-user youngsters had a high occurrence of self-reported halitosis. Higher rates of dental caries are also associated with halitosis.

Sentinel-5P TROPOMI satellite application for NO2 and CO studies aiming at environmental valuation

The European Space Agency (ESA) provides opportunities for researchers on a global scale to identify gaseous pollutants using the most modern techniques of analysis by satellite images from the Sentinel-5P satellite, in the TROPOspheric Monitoring Instrument (TROPOMI), for the formation of current scenarios, applied to valuation environment aimed at possible improvements attributed to air quality and human health. The general objective of this manuscript is to analyze the amounts of NO2 and CO gases with Sentinel-5P TROPOMI satellite images, collected during the year 2019, and apply the environmental valuation focused on air quality pollution, in the northern region of the state of Rio Grande do Sul, in the host city, Passo Fundo (southern Brazil) from 2020 to early 2021. The air quality valuation study applied the Contingent Valuation Method (CVM). The results showed that NO2 had the highest concentration with a value of 7.88e +15 Column mol/cm2. CO presented a value of 9.43e +33 Column mol/cm2. The creation of scenarios aimed at valuation for the application of improvements in atmospheric air quality the understanding of the Willingness to Pay (WTP) of the interviewees. 514 residents of the City of Passo Fundo were queried as to their WTP for clean air quality in the city. The resulting WTP values, when applied to all households in the city as a whole, yielded an average WTP value of R$1,517,478.24 and the median WTP is R$599,390.00. It is suggested that pubic policies be written to enable these, or similar, amounts to be collected annually in order to mitigate harmful pollutants, such as NO2 and CO, currently found in the air of the City of Passo Fundo.

Mechanical behavior and durability of a typical frictional cohesive soil from Rio Grande do Sul/Brazil improved with Portland cement

Lateritic soils are typical of tropical and subtropical climate regions, whose coverage is wide in Brazilian territory. These soils are formed by the leaching of oxides and silicates and are found in unsaturated conditions with a high void ratio due to the presence of macropores and micropores. As a result, the soil has drained behavior and high compressibility. Given these peculiarities, the use of cementing agents can be a suitable solution to promote modifications on the soil’s physicochemical properties to affect bearing capacity and stiffness. This study focuses on the mechanical behavior of typical cohesive frictional soil in the city of Passo Fundo (Southern Brazil) improved by Portland cement of high initial strength (Type III) based on the adopted amount of cement C (%) and γd. Initially, unconfined compression strength tests (qu) were performed for cement contents of 3%, 6%, 9%, and 12%, and γd equal to 16.4 kN/m3, 15.4 kN/m3, 14.4 kN/m3, 13.6 kN/m3, and 12.7 kN/m3, followed by ultrasonic pulse velocity tests to determine the G0. Then, tensile tests were performed through Splitting Tensile Test (qt) considering γd of 16.4 kN/m3, 15.4 kN/m3, and 14.4 kN/m3 for cement contents of 3%, 6%, 9%, and 12%. Finally, the improved soil was studied using durability tests under wetting/drying conditions with γd of 16.4 kN/m3, 15.8 kN/m3, 14.5 kN/m3 and cement content of 3%, 6%, 9%, and 12%. The results indicate that C and γd are sufficiently significant factors in understanding soil’s behavior regarding wetting/drying of the mixtures, in that order. Finally, normalized curves of qu, qt, G0 and LM and VR were developed as a function of the adjusted η⁄Civ for practical purposes of dosages for ground improvement.

Geospatial analysis of Ae. aegypti foci in southern Brazil

Arboviruses have become a major public health problem in recent decades. Ae. aegypti has been the vector responsible for the greatest spread of these diseases. This study aims to identify outbreaks of Ae. aegypti, through the capture of egg traps installed in the City of Passo Fundo, in southern Brazil, to understand the geospatial dimensions aimed at mapping to control the proliferation of these mosquitoes. Methodologically, 20 points were selected for trap placement using an Irregular Triangular Network. Then, ovitrap traps were distributed at the sampled points, during all seasons in 2016 and 2017. From the collected eggs, a colony of wild Ae. aegypti mosquitos was established and stored for future testing. Using geotechnologies, the mapping of each trap was carried out with an accuracy of up to 50 cm. The greatest number of outbreaks occurred in the autumn and summer seasons, with an average temperature of 18 °C and 350 mm of rain, and 22 °C and 300 mm of rain, respectively. Spring and winter, when temperatures are lower, 16 °C and 17 °C, respectively, saw fewer outbreaks. The places that stood out in the study were the two most densely populated and least vegetated areas of the city, Bairro Vila Luiza and the Centro neighborhood. This demonstrates that vegetation suppression and high urban density rates contribute to the proliferation of Ae. aegypti on a global scale.

Use of geospatial tools to predict the risk of contamination by SARS-CoV-2 in urban cemeteries

Urban cemeteries are increasingly surrounded by areas of high residential density as urbanization continues world-wide. With increasing rates of mortality caused by the novel coronavirus, SARS-CoV-2, urban vertical cemeteries are experiencing interments at an unprecedented rate. Corpses interred in the 3rd to 5th layer of vertical urban cemeteries have the potential to contaminate large adjacent regions. The general objective of this manuscript is to analyze the reflectance of altimetry, normalized difference vegetation index (NDVI) and land surface temperature (LST) in the urban cemeteries and neighbouring areas of the City of Passo Fundo, Rio Grande do Sul, Brazil. It is assumed that the population residing in the vicinity of these cemeteries may be exposed to SARS-CoV-2 contamination through the displacement of microparticles carried by the wind as a corpse is placed in the burial niche or during the first several days of subsequent fluid and gas release through the process of decomposition. The reflectance analyses were performed utilizing Landsat 8 satellite images applied to altimetry, NDVI and LST, for hypothetical examination of possible displacement, transport and subsequent deposition of the SARS-CoV-2 virus. The results showed that two cemeteries within the city, cemeteries A and B could potentially transport SARS-CoV-2 of nanometric structure to neighboring residential areas through wind action. These two cemeteries are located at high relative altitudes in more densely populated regions of the city. The NDVI, which has been shown to control the proliferation of contaminants, proved to be insufficient in these areas, contributing to high LST values. Based on the results of this study, the formation and implementation of public policies that monitor urban cemeteries is suggested in areas that utilize vertical urban cemeteries in order to reduce the further spread of the SARS-CoV-2 virus.

Characterization of an area susceptible to floods and inundations in a medium size city in Southern Brazil

The change in precipitation patterns that has occurred over the past decades establishes the discussion about the risks arising from rainfall in urban areas. These risks include floods, inundations and overflow, which are influenced by different conditions. The purpose of this work is to characterize a risk area, susceptible to inundations and floods, in the city of Passo Fundo, in the south of Brazil. In order to propose solutions aimed at mitigating risks for the area, a GIS (Geographic Information System) characterization was applied to prepare thematic maps to identify conditions of infrastructure networks, as well as other constraints of the built environment. The analysis showed that the area, predominantly residential, is currently susceptible to environmental risks, given the proximity to streams, the topography with slopes and impermeable surfaces, despite the existence of rain network infrastructure. Furthermore, the mitigation strategies were proposed, based on the concept of green infrastructure such as the implementation of draining surfaces, rain gardens and a linear park. The data collected in this study will provide subsidies to elaborate the risk maps of the area, deepening the analysis in future studies, assisting the decision making of the public power to prevent and mitigate risks such as floods, according to the identified vulnerability, as well as contribute to Goal 11 - Sustainable cities and communities on the United Nations Agenda 2030.

Co-design: Tactile Models and Prototype as Common Language Tools between Designers and Visually Impaired People

This article presents the use of tactile models and prototype as common language tools among designers, blind and visually impaired (B&VI), inserted in a collaborative design methodology. With the objective of realizing an interior architecture project and an outdoor area, including toys, for an association for visually impaired people in the city of Passo Fundo, RS, Brazil. It describes the process of participation and interaction between Association members, both adults and children, and architects in the development of these projects. It shows results of two co-design actions, which will subsidize a broader objective of a research that aims to define co-design methods, techniques and tools applied to the inclusion of Visually Impaired People in the process of architecture, urbanism, landscaping and interior design. The research related two co-design. The first is the co-design of the waiting / reception room and the external area for socializing and leisure, carried out with the adults of the association, took place in three moments: in the focus group, in the interaction with the tactile model and on the tours accompanied. The second co-design was carried out with the children of the association to develop two toys, the first to be inserted within the proposal of improving reception/ waiting, and the second for placement in the outdoor area of socializing and leisure. The interaction among designers, blind and visually impaired was intensive, allowing modifications and diverse insights about types of floors, layout and better and adequate colors for the best comfort and mobility inside the spaces. It seeks to demonstrate the importance of co-design as a way of including B&VI, as they are able to increase well-being and self-esteem, while effectively participating in the creation of the environment in which they are inserted; they manage to leave the passive zone that they normally find themselves in with regard to the architectural design process. The next steps of the research are to finalize the toy design of the external area and the execution of all spaces.

Real estate production and intra-urban restructuring in Passo Fundo - RS

This article aims to discuss the spread of horizontal condominiums and planned neighborhoods in the city of Passo Fundo - RS, in the decade of 2010. It is assumed that the new real estate products redefine the processes of socio-spatial segregation, showing the dispersion of the classes of middle and high income for peripheral areas, traditionally occupied by the low-income population. The reframing of the periphery denotes the complexification of the intra-urban socio-spatial structure, indicating the emergence of new patterns of socio-spatial segregation, superimposed on the traditional center-periphery model, constituted in the 20th century. In this context, it is argued that it is possible to recognize ongoing common processes, characterized by significant disruptions with the previous logic of production of intra-urban space.

Land surface temperature and vegetation index as a proxy to microclimate

The effect of global climate change on the temperature of urban areas has become more pronounced in the past couple decades, impacting population and quality of life. The United Nations (UN), the National Aeronautics and Space Administration (NASA) and the Intergovernmental Panel on Climate Change (IPCC) have emphasized the impact of urban structures on microclimatic. A better understanding of these effects is important to formulate effective strategies that would contribute to address the impacts of increased urban growth. Here we address a case study of the Vila Rodrigues neighborhood, located in Passo Fundo City in southern Brazil to analyze the variations of emissivity, temperature and vegetation of the terrestrial surface, with influence of buildings. We employ Landsat satellite images, and unpublished data provided by the NASA, interpolated and classified in the QGIS software, using Bands 4, 5 and 10, converted to Gray Level (NC). This procedure allowed the spectral radiance of the reflectance temperature to be obtained. The Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) were used, with correction of emissivity and spectral error, in the identification of the surface temperature of different areas in the Villa Rodrigues. The results showed a total variation of 3.86ºC among the sampled points, which is increased by the difference in significance of the thermal balance in urban areas under open sky with buildings. We suggest that green areas and parks with abundant vegetative cover and the application of new building materials in future constructions would help to improve the urban climate, and such regulation of the local temperature on global scale is an effective step towards addressing the adverse effects from climate change.

Influência das agências de financiamento às políticas públicas de planejamento urbano

Os agentes da produção do espaço urbano sofrem influência de interesses e conflitos que envolvem instituições e setores do mercado e do Estado inerentes ao diferentes dos modelos de desenvolvimento. Para que haja melhorias na qualidade urbana, políticas públicas são necessárias com o intuito de criar – ou recriar – espaços. As políticas que auxiliam na transformação do espaço urbano possuem contornos conceituais poucos significativos e com inúmeros problemas, de naturezas diversas, seja à definição de tributos, efetivação, perspectivas, controle ou avaliação de resultados. Dessa forma, torna-se necessário compreender a relação mutável dos espaços com a cidade, a vida urbana e a “mão invisível do mercado” que é o capital que emerge fora das relações sociais. Esta pesquisa analisa a relação entre as políticas públicas e o BID - financiador para a requalificação do Parque da Gare, influenciando economicamente, socialmente e politicamente na cidade de Passo Fundo, RS. A metodologia é exploratória descritiva, iniciando com a revisão bibliográfica e analisando dados do processo de financiamento da Gare. Diante desta pesquisa, percebemos a forte influência que o mercado do capital tem sobre o desenho e planejamento urbano, reorganizando diretrizes e leis locais.

Patients’ perception about the outcomes of prosthetic treatment in Southern Brazil

Aim: this study assessed the patients’ perception of the outcomes of prosthetic treatment in a University of Southern Brazil. Methods: patients seeking for prosthetic treatment were invited to answer a questionnaire with 41 items about the potential risks, benefits, and consequences of no treatment. Answers were obtained according to a five-item Likert-scale varying from 1 (completely disagree) to 5 (completely agree). Sociodemographic data was included in the comparison. Mann-Whitney or Kruskal-Wallis (95%) compared data depending on the variable. Results: two-hundred twenty-five patients answered the questionnaire. Median age of participants was 45-54 years. The potential benefits were similar among participants irrespective of the variable adopted. The perception of risks was significant influenced by variables gender, age, education level, type of edentulous space, prior treatment with prosthodontics, type of prosthodontics, and prosthodontics usage in years. Consequences of no treatment were affected by age, prior treatment with prosthodontics, and prosthodontics usage in years. Conclusions: the study showed the fundamental importance of correct elucidation about the potential risks (negative perception) in the initial appointment for the studied population. Elucidation about the consequences of no treatment are relevant because some differences were seen into the variables. Prosthodontics patients from the city of Passo Fundo seem well informed about the benefits of the prosthetic treatment, besides the significant influence of some sociodemographic and prosthetic conditions.

Innovative substrates for sugarcane seedling production: Sewage sludges and rice husk ash in a waste-to-product strategy

Recent advances in the sucroenergy production chain include a new way of planting sugarcane based on a method of seedling propagation which requires a significant amount of substrate. Since the sucroenergy sector has been noted as having cleaner energy production, it is imperative that sustainable substrates suitable for the production of sugarcane seedlings be developed. Therefore, the main objective of this study was to develop innovative substrates with solar-dried sewage sludges and rice husk ash to compose substrates for sugarcane seedling production. Batches of sewage sludges were collected in open drying beds from three different municipal wastewater treatment plants from the Rio Grande do Sul State, Brazil: from Passo Fundo city (treated by anaerobic digestion), from Rio Grande city (aerobic digestion) and from Santa Maria city (aerobic digestion). Rice husk ash was obtained from a rice processing industry in the Pelotas industrial region in southern Brazil. The content of trace elements and the pathogenicity of pure sewage sludge (SS) were analyzed. The nutrient content of SS and rice husk ash (RHA) was determined. Twelve substrates with differing ratios of SS, RHA, and vermiculite were formulated to evaluate the subsequent development of sugarcane seedlings. Chemical and physical attributes were determined in all substrates and compared to a commercial substrate. The experiment was conducted in a greenhouse using mini-setts of sugarcane of the RB867515 genotype. Fifteen days after planting the seedlings were evaluated for stalk diameter, shoot height, shoot dry weight and root, and the Dickson quality index was determined. Sewage sludge showed low levels of heavy metals and pathogenic organisms and high contents of nutrients, especially nitrogen, phosphorus and micronutrients such as Zn and Cu, showing promising suitability as a substrate component for seedling production. In general, substrates of all tested proportions of SS and RHA promoted greater shoot and root dry weight and a superior Dickson Quality Index than the commercial substrate used as reference, except for the formulation containing 87.5 % SS. The viability of combining sludges from municipal wastewater treatment plants and rice husk ash into one product was confirmed using a set of biometric attributes and nutrient tissue contents obtained from the production of sugarcane seedlings.

Aleitamento materno e aspectos nutricionais de crianças da escola de educação infantil de uma instituição hospitalar da cidade de Passo Fundo - RS

OBJETIVO: verificar as práticas do aleitamento materno e os aspectos nutricionais de crianças da escola de educação infantil de uma instituição hospitalar na cidade de Passo Fundo – RS. MÉTODOS: foi aplicado um questionário de investigação com variáveis sociodemográficas, práticas sobre aleitamento materno, dados maternos, além de um questionário de consumo alimentar para crianças menores de cinco anos e aferição das medidas antropométricas para avaliação do estado nutricional. Os dados foram digitados e analisados em software de estatística, para as variáveis qualitativas foram apresentadas as frequências absoluta e relativa simples e para as variáveis quantitativas foram calculadas as medidas de tendência central e dispersão. Para as análises de associação foi aplicado o teste qui-quadrado considerando o nível de significância de 95%. RESULTADOS: observou-se neste estudo que a maioria das crianças não recebeu aleitamento materno exclusivo até o sexto mês de vida, conforme recomendação do Ministério da Saúde. Mesmo com prevalência de eutrofia segundo índice de massa corporal/idade, foi constatado que o consumo alimentar das crianças maiores de dois anos em sua maioria encontra-se em risco para futuras complicações quando comparado a menores de dois anos. No entanto foi identificado um fator positivo pelo consumo de frutas, verduras, legumes, carnes e feijão, em ambas as idades. CONSIDERAÇÕES FINAIS: Dessa forma, torna-se fundamental destacar que a influência dos pais em relação à alimentação dos seus filhos deve ser positiva, bem como no ambiente escolar, para que possam juntos atuar como agente transformador nos hábitos alimentares das crianças.

Micorrhizal biotechnology as an alternative to potentialize the strawberry quality

The need to develop and use biotechnology tools to improve management and nutritional techniques in strawberry cultivation are increasing. Based on this, the objective of this study was to test if the mycorrhizal inoculation changes the agronomic and qualitative performance of strawberry fruits. The strawberry daughters plants used were of the cultivar Camarosa. The study was carried out in an agricultural greenhouse, Horticulture Sector of the Faculty of Agronomy and Veterinary Medicine (FAMV) of UPF, in the city of Passo Fundo, Rio Grande do Sul (RS), Brazil. The experiment was developed and maintained from June to December 2015. The treatments consisted of five inoculum: T1 = no inoculum (control); T2 = Acaulospora morrowiae; T3 = Rhizophagus clarus; T4 = mycorrhizal community; T5 = Claroideoglomus etunicatum. The experimental design was a randomized block with four replicates. Each plot consisted of a bag containing 6 plants spaced 0.15 mx 0.15 m. In the pits of the plants, it was applied, with the aid of syringe and water, about 70 infective propagules of the tested inocula. During the conduction of the experiment the temperature and photosynthetically active radiation (PAR) were monitored in the culture environment. It was evaluated the agronomic and qualitative performance of the fruits and the percentage of mycorrhizal colonization of the plants roots. The data were submitted to analysis of variance and the differences between means were compared by the Tukey test at 5% of probability error. The cultivar Camarosa produced more fruits in October. In September, the month before the one with the best agronomic performance, the mean temperature was 17.7 ºC. The mean PAR recorded in the growing environment was low in relation to crop requirements, throughout the growing period. Fruits produced by plants inoculated with A. morrowiae presented higher values of TSS/TTA ratio in September and October. The percentage of mycorrhizal colonization varied from 26.2% for A. morrowiae to 46.2% for R. clarus. The inoculation of arbuscular mycorrhizal fungi does not alter the production of strawberry fruits. However, when the plants are inoculated with A. morrowiae there is an improvement in the fruit flavor.

Urban Rules and Morphology Analysis as Support to Solar Performance in Passo Fundo/RS, Brazil

The expansion and densification of cities should be planned to ensure minimum health conditions for buildings. In this sense, this study is interested in the right to solar access for buildings using the analysis of solar envelope to propose urban forms that guarantee this right. The study is in the exploratory phase, and it is applied to the city of Passo Fundo, Brazil. The study started from an analysis of the pre-existing morphological structure, and the solar envelope was generated using the Ladybug tool plugins for Grasshopper and Diva applications in Rhinoceros software. The results showed that the pre-existing urban form has low solar performance, evidencing the need to review construction rules according to the pattern and positioning of lots. Thus, it is expected to be counterbalanced by the revision of urban rules, proposing subsidies for the reformulation and adequacy, or creation of new legislation.

Arquitetura Art Déco: um estudo sobre o seu valor para a história e memória da cidade de Passo Fundo/RS, Brasil

O presente artigo tem o objetivo de apresentar e analisar as edificações com características Art Déco situadas na região central da cidade de Passo Fundo/RS, representativas de transformações socioespaciais modernizadoras. A sua valorização e reconhecimento como patrimônio cultural é de fundamental importância para que os fatos urbanos dessa cidade permaneçam como história e como memória. No Brasil, a arquitetura Art Déco marcou significativamente o cenário das cidades entre as décadas de 1930 e 1950, sendo uma expressão de modernidade acessível às diversas classes sociais da época. Por isso, há muitas perspectivas de análise para essa arquitetura, particularmente na sua difusão no estado do Rio Grande do Sul, Brasil. A cidade brasileira de Passo Fundo, situada na região norte desse estado, possui um significativo repertório de arquitetura Art Déco em sua área central, no entanto, essa arquitetura não se encontra circunscrita sob a legislação preservacionista do poder público municipal. Tal conjuntura, carece de um debate acerca do valor patrimonial desses artefatos para a cidade pelo motivo desse conjunto arquitetônico ainda não ter sido relacionado no cadastro municipal de bens de valor histórico patrimonial, o que evidencia uma falta de compreensão do valor dessa arquitetura como representativa de um momento histórico da cidade. Esse cadastro é uma lista onde estão relacionados os bens de valor patrimonial da cidade de Passo Fundo/RS.
