The objective was to investigate the influence of meteorological and air quality variables on the functional capacity of patients with CRD. This was a descriptive, retrospective and cross-sectional study of information collection in a database from 2016 to 2019. For the analysis of environmental variables, three different databases were used, one from the automatic air quality monitoring station in Novo Hamburgo, and the weather stations of Novo Hamburgo and Campo Bom (RS). The monitored data were: NO<sub>2</sub>, CO, O<sub>3</sub>, PM<sub>10</sub>, PM<sub>2,5</sub>, average temperature, minimum temperature, maximum temperature, precipitation, average wind speed and relative humidity. The sample consisted of 85 individuals from the Pulmonary Rehabilitation Program (PRP), where the variables spirometry and six-minute walk test (6MWT) were collected. It was observed that the higher the concentration of PM<sub>10 </sub>and the higher the minimum temperature, the lower the spirometric results. Furthermore, the greater the concentration of PM<sub>2.5</sub>, the shorter the distance that the individual travels. A relationship was found between environmental data and functional tests, where individuals with CRD are more sensitive to high levels of air pollutants, as well as to lower temperatures.</p> Eduarda Sthefanie Mittelstadt, Daniela Müller de Quevedo, Cássia Cinara da Costa, Daniela Montanari Migliavacca Osorio, Rafael Machado de Souza, Daiane Bolzan Berlese Copyright (c) 2022 Ciência e Natura Fri, 23 Sep 2022 00:00:00 -0300 Precipitation schemes by quantile technique and its water balances in Barbalha - CE, Brazil <p>The climate of a region results from the different combinations of atmospheric processes with a diversity of typology. The objective is to analyze rainfall fluctuations and their temporal fluctuations using the quantile technique applied to the study of rainfall for different rainfall regimes, very dry (MS), dry (S), normal (N), rainy (C) and very rainy (MC), together with the water balances, for Barbalha - CE, between 1973 and 2019. It used the monthly rainfall and thermal values, acquired from the National Institute of Meteorology. Values smaller than 922.90 mm, 17 MS events between 922.90 and 1083.23 mm, 13 S events between 1083 and 1210.79 mm, 6 N events between 1210.79 and 1294.79 mm and 4 events were observed C, rainfall greater than 1294.79 mm in 8 MC events. There are rains from January to April, regarding the replacement of water in the soil and the creation of surplus, different responses were observed. The quantile methodology and the water balance make it possible to understand the rainfall regimes, being indispensable for the planning of agricultural activities, bringing benefits to the local society.</p> Luciano Fallé Saboya, Raimundo Mainar Medeiros Copyright (c) 2022 Ciência e Natura Thu, 22 Sep 2022 00:00:00 -0300 Impacts of the ocean-atmosphere coupling into the very short range prediction system, during the impact of Hurricane Matthew on Cuba <p>The main goal of this investigation is analyzing the impact of insert the ocean-atmosphere coupling into the very short range prediction system of Cuba. The ocean-atmosphere coupled components of the Coupled Ocean-Atmosphere-Wave-Sediment Transport Modeling System are used for this purpose and the hurricane Matthew is selected as study case. Two experiments are performed: first, using a dynamic sea surface temperature, updated daily in the atmospheric model WRF; and second using a dynamic coupling between the atmospheric and an oceanic models. For the simulated track, the best results are obtained with the coupled system. The impact of coupling on the maximum wind velocities and minimum central pressure is studied. In the coupled system the sea surface temperature has more influence in the surface latent heat fluxes. Also, with this methodology the dry footprint and the behavior of the precipitation field in the presence of a hurricane are studied. This analysis shows that the hurricane acts like an open and self-sustained system in the numerical experiments. The highest differences in the precipitation simulations are in the significant convective area inside the hurricane.</p> Liset Vázquez Proveyer, Maibys Sierra Lorenzo, Roberto Carlos Cruz Rodríguez, John C Warner Copyright (c) 2022 Ciência e Natura Thu, 22 Sep 2022 00:00:00 -0300 Strategic plan to achieve the SDGs in South Brazil: evidence from the Regional Development Council articulated with the 2030 Agenda <p>The Regional Development Councils (Coredes), created in 1994, have become spaces for discussion of public policies, promotion of governance, and citizen participation in the multiple areas in which the public power operates. In this task, the Councils assume the work of elaborating the strategic plans of regional development. The 28 Coredes of the state of Rio Grande do Sul, Brazil, promote this work responsibility and periodically carry out its evaluation and eventual correction every 10 years, financed by the state government. The last review process, which ended in July 2017, was a process carefully handled by a team of technicians from a university. Universities contribute as articulators to achieve Sustainable Development Goals. This study aims to analyze the methodologies used in this participatory process, the strategies defined, and the proposed projects linked to the 2030 Agenda by the United Nations. From the diagnosis, it was possible to identify the potentialities and challenges for Strategic Development Planning in the region.

The objetive of study was evaluate the levels of exhaled carbon monoxide (COex) and carboxyhemoglobin (COHb) in steakhouse workers. This is an observational, longitudinal and prospective study in the city of Cuiabá, Mato Grosso, Brazil. The total of 29 professionals working in steakhouses participated in the study. Data on socio-demographic characteristics, work environment characteristics, life habits and respiratory symptoms were extracted from questionnaires. COex and COHb levels were measured before exposure and every hour up to a 4 hour exposure period. Twenty-nine workers participated, with a predominance of females (55.2%), with a mean age of 36.40±11.49 years. It was observed that 18 (62%) of the workers had respiratory symptoms. COex and COHb levels were elevated after 4 hour exposure (p&lt;0.05), but within acceptable parameters. COex and COHb levels are elevated in a short period of time to occupational exposure to steakhouse activities.</p> Igor Rian Bonelli de Oliveira, Osvaldo Borges Pinto JR, Silkiane Machado Capeleto, Cristhiane Almeida Leite da Silva, Walkiria Shimoya-Bittencourt Copyright (c) 2022 Ciência e Natura Fri, 23 Sep 2022 00:00:00 -0300 Study of biofilms with kefir associated with soy germs (Glycine max (L.) Merril) <p>The aim of this study was to investigate biofilm formation with kefir grains in the presence of soy extract. Kefir grains and soy germs at different concentrations were grown in the culture medium comprising brown sugar solution (40 gl<sup>-1</sup>) for 20 days. Biofilms that formed in this period were then removed and the pH of the culture medium were measured. Isoflavones of the medium of culture were extracted and quantified by high-performance liquid chromatography (HPLC). The superficial properties of the selected biofilms were analyzed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The culture medium after 20 days was found to have 19.59±3.57 µgl<sup>-1</sup> of glycitein and 23.86±2.21 µgl<sup>-1</sup> of genistein. The best concentration of kefir grains in order to extract isoflavone was 40 gl<sup>-1</sup>, with yield levels at 11.67 µgl<sup>-1</sup> of glycitein and 17.78 µgl<sup>-1</sup> of genistein. The analysis by AFM and SEM confirmed the increased roughness of the biofilm, dependent of the concentration of the amount of kefir grains. It is suggested that the biofilms incorporated the isoflavones and has potential for therapeutic applications in several pathologies wherein it is necessary the antioxidative processes.</p> Antonio Ferreira Oliveira, Alexandro Cezar Florentino, Adriana Ferreira Maciel, Adriana Santos Valente, Roberto Messias Bezerra, Robert Maguiña Zamora, Jose Tavares Carvalho Copyright (c) 2021 Ciência e Natura Thu, 15 Apr 2021 00:00:00 -0300 Study of the relation of air quality and meteorological variables in the occurrence of respiratory morbidity <p><span class="TextRun SCXW73390503 BCX0" lang="EN-US" xml:lang="EN-US" data-contrast="auto"><span class="NormalTextRun SCXW73390503 BCX0" data-ccp-parastyle="Texto resumo/abstract" data-ccp-parastyle-defn="{&quot;ObjectId&quot;:&quot;de0c0d3e-0732-4c8d-b494-acd7ac5c8484|92&quot;,&quot;ClassId&quot;:1073872969,&quot;Properties&quot;:[469775450,&quot;Texto resumo/abstract&quot;,201340122,&quot;2&quot;,134234082,&quot;true&quot;,134233614,&quot;true&quot;,469778129,&quot;Textoresumoabstract&quot;,335572020,&quot;1&quot;,469777841,&quot;Open Sans&quot;,469777842,&quot;Times New Roman&quot;,469777843,&quot;Times New Roman&quot;,469777844,&quot;Open Sans&quot;,469769226,&quot;Open Sans,Times New Roman&quot;,335551500,&quot;4278190080&quot;,268442635,&quot;20&quot;,335559705,&quot;2052&quot;,335559740,&quot;240&quot;,201341983,&quot;0&quot;,335559739,&quot;120&quot;,335559738,&quot;120&quot;,335551550,&quot;6&quot;,335551620,&quot;6&quot;,134233279,&quot;true&quot;,335560102,&quot;4&quot;,134245418,&quot;false&quot;,469777929,&quot;Texto resumo/abstract Char&quot;,469778324,&quot;heading 5&quot;]}" data-ccp-parastyle-linked-defn="{&quot;ObjectId&quot;:&quot;de0c0d3e-0732-4c8d-b494-acd7ac5c8484|93&quot;,&quot;ClassId&quot;:1073872969,&quot;Properties&quot;:[469775450,&quot;Texto resumo/abstract Char&quot;,201340122,&quot;1&quot;,134233614,&quot;true&quot;,469778129,&quot;TextoresumoabstractChar&quot;,335572020,&quot;1&quot;,134231262,&quot;true&quot;,469777841,&quot;Open Sans&quot;,469777842,&quot;Times New Roman&quot;,469777843,&quot;Times New Roman&quot;,469777844,&quot;Open Sans&quot;,469769226,&quot;Open Sans,Times New Roman&quot;,268442635,&quot;20&quot;,335559705,&quot;2052&quot;,469777929,&quot;Texto resumo/abstract&quot;]}">A</span><span class="NormalTextRun SCXW73390503 BCX0" data-ccp-parastyle="Texto resumo/abstract">tmospheric pollution is responsible for several damage</span><span class="NormalTextRun SCXW73390503 BCX0" data-ccp-parastyle="Texto resumo/abstract">s</span><span class="NormalTextRun SCXW73390503 BCX0" data-ccp-parastyle="Texto resumo/abstract"> to human health.

This concept aimed to provide a balance between the economic, social, and environmental dimensions. In order to consolidate the framework, it is important to identify the concepts related to sustainability that are being used in the context of sustainable construction. This paper performed a systematic review on the TBL concept applied to sustainable construction, from 2010 to 2021, in the following databases: Scielo, Scopus, and Science direct. Initially, 739 papers were found; 169 made it through the primary screening and 33 were selected after reading the abstracts and removing duplicates. An increase in TBL-related research was observed in the last 10 years, specifically in the field of sustainability of buildings. Likewise, new concepts have been incorporated, such as circular economy, which may result in new ways to support sustainable development.

In methodological terms, this case study is empirical and exploratory. The Balance Sheet of Nations accounting technology allows identifying countries’ environmental assets, liabilities, and equity. The environmental water asset based on the region’s gross domestic product is determined, the environmental net worth by the residual balance of the water reserves, and the environmental water liability by accounting equivalence using the Basic Accounting Equation. Results showed a surplus of US$ 3.04 per capita in 2017 and a deficit of US$ 12.68 per person projected for the year 2050. This result offers the possibility that the municipality of Alagoinhas does not have water resources in the year 2050. It also points to the importance of how inhabitants should take care of their water resources in the coming decades and contributes to future research highlighting the relevance of accounting information aimed at these natural resources’ patrimonial situation.</p> Jozenei Silva Pereira, Frederico Fonseca de Silva, Luiz Panhoca, Joselisa Maria Chaves, Alexandre Machado Fernandes Copyright (c) 2022 Ciência e Natura Mon, 08 Aug 2022 00:00:00 -0300 Briology studies in the northern region <p>This article is a literature review aimed at answering the following question: Over the past 30 years, research on bryophytes in northern states has intensified, allowing the identification and conservation of the biological diversity of bryophytes in this region. region?

This study aimed to determine the water quality of the Rio dos Sinos watershed in South Brazil by analyzing genotoxicity and environmental factors of four sub-basins in two periods (P1 = 2012 – 2013 and P2 = 2018 – 2019). Water genotoxicity was analyzed using the micronucleus test with Tradescantia pallida var. purpurea. In parallel, a Rapid Habitat Assessment Protocol (RHAP) was employed and data on physico-chemical parameters, land use and occupation and the number of inhabitants were collected and examined for possible relationships with genotoxicity. Genotoxicity did not differ significantly over time for three of the four studied sub-basins. There was a significant relationship between water genotoxicity and number of inhabitants. Furthermore, environments with high genotoxicity, low water quality and high environmental degradation in the first monitoring period remained in the same condition in the second monitoring period; the most preserved areas of the basin may come to resemble these environments in the future.</p> Luciana Rodrigues Nogueira, Mara Betânia Brizola Cassânego, Dra Copyright (c) 2022 Ciência e Natura Fri, 23 Sep 2022 00:00:00 -0300 Titanium dioxide nanoparticles promote histopathological and genotoxic effects in Danio rerio after acute and chronic exposures <p>Titanium dioxide nanoparticles (TiO<sub>2</sub>-NPs) are among the most used nanomaterials worldwide, but studies evaluating its genotoxicity and histopathological effects are scarce, dealing with short exposure times and low concentrations for human use. The aim was to evaluate TiO<sub>2</sub>-NPs genotoxicity and histological alterations in the intestine and liver of zebrafish after exposure to human consumption compatible concentrations. Fishes were acutely (96 hours) and chronically (30 days) exposed to 5.0, 20 and 40 mg L<sup>-1</sup> of TiO<sub>2</sub>-NPs and later euthanized for organ and blood analysis through histological procedures and the micronucleus test, respectively. An increase in the thickness of intestinal villi was observed after acute and chronic exposure in the higher concentrations. The liver showed an increase in vacuolated hepatocytes after both exposures, besides an increase in hepatocytes with peripheral nucleus. Genotoxicity was only observed after chronic exposure, demonstrated by the increase in micronucleus and cell buddings. These findings indicate that TiO<sub>2</sub>-NPs cause histopathological damage even in acute exposures, as the intestine serves as a barrier for NPs and the liver is an organ that accumulates Ti. Genotoxicity was possibly mediated by reactive oxygen species through chronic inflammation, leading to tissue damage and carcinogenesis in longer exposures that represents human exposure time.</p> Juliana Machado Kayser, Andriéli Carolina Schuster, Gabriela Zimmermann Prado Rodrigues, Fernando Dal Pont Morisso, Günther Gehlen Copyright (c) 2022 Ciência e Natura Tue, 31 May 2022 00:00:00 -0300 Determination of pesticides in hydroponic water for environmental phytoremediation This study validated a simple, and fast method by High Performance Liquid Chromatography with Diode Array Detector (HPLC -DAD) for pesticide phytoremediation analysis. The method was developed in water and in a hydroponic medium. Sample extraction and concentration were performed by Solid Phase Extraction (SPE) with Strata C18-E type cartridges. The SPE-HPLC-DAD method was successfully applied in the detection and quantification of quinclorac, 2,4-D, propanil, bentazon, clomazone and tebuconazole in water and hydroponic medium for 14 days. The method presented excellent results with the linearity of 0.9969 - 0.9994 and the lowest limit of detection (LOD) and quantification (LOQ) of pesticides was 1.7 μg/L and 5.0 μg/L, respectively with RSD &lt;11.92%.

In this sense, this article presents an analysis of correlation between burn hotspots, pasture areas and bovine production for the State of Rondônia. Research products were deployed such as maps to demonstrate spatial relationship, graphs to demonstrate the historical series and charts to demonstrate the correlation between the variables. Due to the non-adherence of data to normality, Spearman's correlation coefficient was used. Softwares ArcGis version 10.1 and Jamovi version 1.6 were used. The correlation between fires and bovine production in the State was significant, positive and with a week/moderate tendency, with evidence values ranging from 0.282 to 0.400; while for correlation between pasture areas and forest fires was significant with a trend ranging from 0.485 to 0.633; between bovine production and pasture areas, there is a strong correlation with a significative positive trend from 0.833 to 0.914. It is possible to verify an increase in the values of the variables throughout the time series, and correlation between them.

The principle of bioeconomy is to seek to reduce the negative socio-environmental impacts that the development model, based on fossil fuels, has been causing on the planet. The United Nations works for a new global governance aligned with the Sustainable Development Goals, paying special attention to global and territorial demands related to climate change mitigation, the promotion of sustainable agriculture, and the production of cleaner renewable energy. However, promoting a sustainable bioeconomy is not a neutral notion. Each of the stakeholders, researchers, governmental or supranational organizations tend to favor conceptual approaches, which aim to favor local opportunities. Thus, this theoretical essay aims to reflect on the conceptual approaches of the terms bioeconomy and sustainable bioeconomy. Specifically, it seeks to know how conceptual approaches apply to the material realities of the stakeholders who undertake them. Due to the methodological procedures adopted, it was possible to verify that the absence of a consensus regarding the term bioeconomy has to do with the vision focused on the interests of each stakeholder, which seeks to provide opportunities for the achievement of its objectives.</p> Kalil Nascimento Neiva, Ana Carolina Nogueira Gonçalves, Bruno Gouvêa Bastos, Alexandre de Meira Vasconcelos, José Carlos de Jesus Lopes Copyright (c) 2022 Ciência e Natura Tue, 19 Jul 2022 00:00:00 -0300 Dialogues among stakeholders of sugar-energy sector: an analysis of the institutional environment with sights to the social and environment factors <p>Brazilian sugar-energy sector has being defended as a sustainable alternative, as well as innovator for the energy matrix of the country. The sector is not only dependent on the innovative capacities of individual firms and the state policies, but on the interaction among the other stakeholders involved. It is about a descriptive and exploratory research of qualitative nature. The objective was to analyze how the dialogues among stakeholders occur<em>, </em>concerning social and environmental factors, in the institutional environment of the sugar-energy sector, in Mato Grosso do Sul. Interviews with six stakeholders linked to the sugar-energy sector were performed, besides a documentary analysis. Category content analysis was applied. It was evidenced that stakeholders make use of dialogue approaches as a strategic tool to identify the needs of improvements on sugar-energy sector before the institutional changes, making possible the integration among the different links of the sugar-energy sector to ease the conflicts of interests. The development of the sector is based on sustainable practices. The results highlight that the dialogue approach generates effective results, which propitiate more local sustainable development, encouraging the ecobusiness.</p> Paula Silva Santos, Denise Barros Azevedo, Erlaine Binotto, Silvia Morales de Queiroz Caleman, Guilherme Cunha Malafaia Copyright (c) 2022 Ciência e Natura Fri, 23 Sep 2022 00:00:00 -0300 Conceptual frontiers about sustainable cities, smart cities and bioeconomy terms: What do scientific researchs, published in literature, have to say? <p>Discussions on Sustainable Cities, Smart Cities and Bioeconomics have become more comprehensive over the past few decades, considering the need for the applicability of sustainability among the various human activities around the planet.

The aim of this study was to describe the RL process of gas stations and their tax benefits, through bibliographic and documentary research, in addition to an unstructured interview with professionals involved in the process and through a case study. It was found that compliance with environmental obligations imposed by the Government, such as the destination of used or contaminated lubricating oil packaging (OLUC), can be considered inputs that may generate PIS and COFINS credits, and the revenues obtained from the sale of the destination of OLUC may be considered as environmental revenues, as well as the structure of real estate to be measured as environmental assets.</p> Mayara Fernanda Simões, Paulinho Rene Stefanello, Frederico Fonseca da Silva, Alexandre Machado Fernandes Copyright (c) 2022 Ciência e Natura Wed, 06 Jul 2022 00:00:00 -0300 Energy efficiency project: analysis of the installation of photovoltaic panels at the Curitiba City Hall <p class="Keywords">Brazil stands out for the use of renewable energy sources in its energy matrix. Even so, it suffers from the risks of collapse and depletion of resources, as occurred in the beginning of the 21st century. In view of this, there is a need to promote growth in the use of other less polluting energy sources, such as photovoltaic solar energy. Some factors contribute to the growth in the use of this technology, such as: scarce rains, constant increases in electricity tariffs, tax exemption and expansion of credit lines that guarantee resources for the best use of abundant solar radiation. In this context, this study aimed to analyze the feasibility of implementing the solar energy generation system, from the installation of photovoltaic panels, in the Curitiba (Brazil) City Hall, seeking to encourage the expansion of access to photovoltaic energy, as a way to reduce spending on electricity, preserving the environment and maximizing the municipality's energy efficiency.

Initially, the inconsistencies in the database were identified and adjusted. Then, the descriptive statistics were estimated using the Kaplan-Meier (KM) method, evaluating its applicability in different censored data sets. The descriptive parameters were compared with the substitution method. The substitution method showed susceptibility to biased estimates, especially for groups of compounds containing high percentage of censored data and with high limits of quantification and detection, leading to higher descriptive parameters compared to KM method. This work reinforces the need to use appropriate methods for analyzing environmental data and evidences that the analysis of this type of data may be complex.

In this scenario, society is challenged to increase food availability while reducing pesticide use, which causes damage to health and the environment. In this sense, essential oils appear as a promising alternative to reduce the use of pesticides, since they are plant-derived compounds. This study aimed to identify the main chemical components and evaluate the in vitro antimicrobial potential of essential oils of the Brazilian species <em>Elionurus latiflorus</em> and the exotic species <em>Cymbopogon flexuosus</em> against the phytopathogenic bacteria <em>Xanthomonas axonopodis</em> pv. <em>phaseoli, Ralstonia solanacearum, Pectobacterium carotovorum </em>pv.<em> carotovorum </em>and<em> Pseudomonas syringae </em>pv.<em> tomato</em>. The main component identified of the essential oils was citral at the concentrations 65.38% for <em>E. latiflorus</em> and 71.6% for <em>C. citratus</em>. The analysis of the antibacterial activity of the essential oils showed effect against all bacteria analyzed when compared to the antibiotic gentamicin. The antibiotic produced inhibition zone diameters from 11.30 to 20.67 mm, while the essential oils produced the inhibition zones from 51.22 to 90 mm and pure citral around 86 mm. MIC values for essential oils were found between 25 and 200 µL/mL and MBC between 100 and 400 µL/mL.

The works published in ENPEC, from 2011 to 2019 (5 editions) were analyzed, searching for the following descriptors, initially separated: metacognition, metacognitive, metacognitive, teaching knowledge, teaching knowledge, teacher training, teacher training, Early Childhood Education and Early Childhood Education; then in the combined form: teacher training and teaching knowledge; Early Childhood Education and teacher training; teacher education and metacognition; teacher training and metacognition and, in trios, teacher training, teaching knowledge and Early Childhood Education. Through the literature review, it was possible to categorize the descriptors in to three focuses of discussion: teacher education, knowledge and metacognition. As a result, we know that to teach Science, teachers mobilize knowledge from experience, but the critical reflection of their practice is a major gap highlighted in this work. Thus, more research on this topic is suggested for the construction and development of this metacognitive knowledge in which processes such as reflection, monitoring, rethinking, self-assessment can be inter connected in teaching pedagogical practices.</p> Adriana Bigido Rocha, Solange Wagner Locatelli Copyright (c) 2022 Ciência e Natura Fri, 23 Sep 2022 00:00:00 -0300 Educação inclusiva no ensino de ciências e de química - uma revisão da literatura sobre as propostas pedagógicas direcionadas a estudantes com desenvolvimento atípico <p>This article aims to analyze how the perspective of Inclusive Education is being addressed in research in ​​Teaching Science and Chemistry, to identify pedagogical proposals for students with atypical development in the cognitive dimension, such as those with intellectual or multiple disabilities, syndromes, disorders developmental disorders, high abilities/giftedness or other learning disorder.

This is one of the oldest approaches to Astronomy as a science, being used by ancient Greeks and possibly by other people before that. Concerning a more formal current mathematical description, there are several types of coordinate systems with respect to the celestial sphere. Each system differs in the choice of its referential plan. Several connections between elements of different types of coordinates are well known once it is a well-developed field. However, the reader will not find in the literature complete mathematical proofs for such formulas. Thus, this article fills that gap.

The installation of artificial perches should be encouraged in degraded areas, because they facilitate the visitation of birds and seed dispersal, contributing both to the arrival of seeds and to an increase in seed richness in the area.</p> Allencar Jorge Kasper Branco, Juliano Cordeiro, Suzana Stefanello, Victor Pereira Zwiener Copyright (c) 2022 Ciência e Natura Wed, 29 Jun 2022 00:00:00 -0300 Free-living protozoa (ciliophora, excavata and amoebozoa) in two water sources for human supply in the municipality of Blumenau, SC The knowledge of the diversity of free-living protozoa in aquatic ecosystems represents an important tool in environmental quality management. It has been widely used in studies evaluating the water quality of fresh-water sources with environmental variables. Therefore, this study aimed to verify the diversity of free-living protozoa in two water sources used as a public supply for human consumption in the municipality of Blumenau, SC, for 12 months. Water samples were collected monthly for analysis of environmental variables and for identification of organisms. In total, 39 taxa were recorded in P1 and P2, both in the readings performed on the day of collection and in the cultivation. In P1, 11 taxa were identified in the readings of the day of collection, and after reading the cultivation, 20 new taxa were recorded. P2 presented 12 taxa in the readings performed on the day of collection and 10 new taxa in the cultivations' readings. Ciliates were the most expressive group in the period, with 69.5% frequency in P1 and 66.1% in P2. The results of the environmental variables in conjunction with the survey of the free-living protozoa of P1 and P2 did not show marked differences between the points. Still, they contributed to the knowledge of the diversity of protozoa in aquatic environments.

The evaluations of the water parameters, contemplating the studies on the spatio-temporal variations, the nicthemeral alterations (changes throughout the 24 hours of the day) and the vertical distribution of these parameters along the water column, are important for the knowledge about the water quality and understanding of ecological processes in aquatic environments. Environmental concern is growing in the Lake Guaíba hydrographic basin, since the organic load input from the forming rivers, especially the Gravataí and Sinos rivers compromise the water quality in the Jacuí Delta. In the present work, the physical and physical variables of the water were evaluated in two sampling points, no left channel (Canal Navegantes) and no right channel (Canal Jacuí), both sharing in Delta do Jacuí, in Porto Alegre and Eldorado do Sul, LOL. The pH, dissolved oxygen, temperature, turbidity and electrical conductivity values were collected in the water column at three depths (surface, medium, deep), in September and November 2019 and January and February 2020, with the help of portable equipment, in a 24h profile. Through analysis of variance, it was found that for pH, the mean values in surface water were higher. Conductivity and OD spatially differed. Through correlation, positive values of temperature with pH (0.46), pH with oxygen (0.30) and negative values for conductivity and dissolved oxygen (-0.55) were detected. The (PCA), when the main component 1 and 2, together represent 75.62% of all data variation. For the months, there was a difference between all. The sampling sites showed thermal inversion in September and November and thermal and chemical stratification in February.</p> Marco Vinicius Martins, Simone Caterina Kapusta, Cristiano Poleto Copyright (c) 2022 Ciência e Natura Wed, 29 Jun 2022 00:00:00 -0300 Hydrological modelling applied to flooding assessment in the urban coastal city in Brazil <span>The urban region of many coastal municipalities is marked by the growing process of urbanization of its marine river plain and presents great challenges related to the drainage of rainwater. This study seeks to verify the influence of the flood wave, coming from the upper part of the Macaé River hydrographic basin, in the flooding of the urban area, using MOHID platform, Land module, for the hydrodynamic simulation. The municipality of Macaé, located in the north of Rio de Janeiro (Brazil), has a dense network of tributary channels, built to drain more quickly the waters that accumulate in the floodplains during the rainy seasons. The current configuration of this system is insufficient to reconcile the current land use and runoff, and the floods impose several economic losses. Given this scenario, the Hydrographic Basin Committee of the region, through its Water Resources Plan, recommended studies on the theme, pointing out the need for a more detailed topographic description. The results of the model were compared with a rain that occurred in March 2018, which caused flooding in various points of the urban area. The methodology used can be applied in other municipalities with the same need.</span> Marcos da Silva Lourenço; Ariana Paula Pernambuco Mafra; Francine de Almeida Kalas, Pedro Paulo Gomes Watts Rodrigues, Maria Inês Paes Ferreira, Jader Lugon Junior Copyright (c) 2022 Ciência e Natura Thu, 14 Jul 2022 00:00:00 -0300 Performance evaluation in the acquisition of meteorological data from a low cost station for water sports practitioners <p>Outdoor water sports practitioners need information about the meteorological elements in the place where they practice it, however, the information available most of the time does not take into account the specificities of the surroundings and does not contemplate the real situation. The objective of this study is to develop a weather station with real-time data transmission, for a communication application for water sports players' cell phones. The methodology was divided into three stages: elaboration of a prototype of a weather station with low cost sensors; comparison of meteorological elements obtained in the prototype and IFSC Campus Florianopolis station and transmission of meteorological elements measured by the prototype via 4G network, in real time. Field tests and adjustments in the development phase of the station were carried out at the Florianopolis Campus of the Federal Institute of Santa Catarina (IFSC), by comparing the data from the developed station and a portable weather station from Vaisala brand model WXT510. Data transmission took place with the development of a communication module coupled to a cell phone with OTG technology. As a result, the comparison between the meteorological elements measured between the stations obtained a Spearman correlation of 0.972; 0.929; 0.989; 0.944 and 1, respectively for wind speed, wind direction, air temperature, relative air humidity and atmospheric pressure, indicating that in all measured meteorological elements the time series are strongly correlated.</p> Sergio Roberto Sanches, Cássio Aurélio Suski Copyright (c) 2022 Ciência e Natura Tue, 31 May 2022 00:00:00 -0300 Sensory Garden of the space for living with the semiarid environment (e-CASA) as a tool for botanical teaching in elementary school <p>The present study is an activity carried out in the sensory garden (J.S.), which integrates the extension program Living Space with the Semiarid Environment - e-CASA, locus for carrying out the actions of the Extension Program: Agroecological and environmental education: dialogues between and school for living with the semiarid region. This garden aims to provide sensory experiences to visitors, through the use of plants, which can be used as a resource for scientific and didactic purposes. In order to verify the effectiveness of activities developed at J.S. of the e-CASA, as a didactic tool for teaching Botany in the final years of Elementary School, students from a public school in Picos were invited to participate in the research. It is noteworthy that the project was carried out after approval by the Research Ethics Committee, and students could only participate with formal consent of their parents or guardians. During the guided tour, data were collected from systematic observation and through student reports. Subsequently, semi-structured questionnaires were applied in order to obtain information regarding the study and analyze the level of satisfaction of the subjects involved with the activities developed. The results obtained show that 76,7% of the participants felt satisfied with the sensory experience, giving it maximum grade. It was also observed a large number of correct answers regarding the recognition of plants present in the sensorial garden, 53.3% identified more than one specimen and 46.7% at least one of the plants presented, and the most used sense for the effective identification of these plants was the tact. Thus, it was concluded that activities of this nature are necessary, as they encourage students to become active subjects of their learning and allow them to recover previous knowledge aiming at the construction of scientific knowledge.</p> Paula Virginia do Nascimento Silva, Amanda Macêdo Rocha, Juliana do Nascimento Bendini, Maria Carolina de Abreu Copyright (c) 2022 Ciência e Natura Fri, 23 Sep 2022 00:00:00 -0300 Flood risks in regularized watersheds: Case study of the flood in the Mondego River, Portugal <p>Hydrological studies of flooding in watersheds with a high hazard of inundation are important for mitigation and prevention methodologies. The Mondego river flooding, which occurred in Portugal in 2001, with 460.1 mm total month precipitation around the city of Coimbra, generated great economic and social losses. This study proposed to calculate the flood Return Period (RP) that occurred in 2001 using a methodology developed for the analysis of flood risk in regularized basins. The information used in this analysis was data of precipitation and reservoir average level. The results showed that the 2001 Mondego River flood has an RP of 439.4 years. The combination of precipitation and reservoir data proved to be important to understand the dynamics of floods in a regularized basin. In this sense, the proposed methodology can be applied to any basin that is heavily influenced by upstream reservoirs.</p> Marcelle Martins Vargas, Gustavo Willy Nagel, Maíra Martim de Moura Copyright (c) 2022 Ciência e Natura Wed, 06 Jul 2022 00:00:00 -0300 Some properties of the set of Liouville numbers <p>The present work consists on the introduction of the Transcendental Number Theory beginnings. First, we will present the classical theorems of the rational approximations, finishing with the theorem of Hurwtiz-Markov. The following part is about Liouville Numbers and their intrinsic properties, proving their transcendence. Also, we will talk about the measure of irrationality, an interesting way to classify the degree of irrationality of certain real number. The last (but not least) topic is about the Liouville numbers as a set and their paradoxes, this set, in the view of the topology, is the complement of a Meagre set, which this means that is "big". However, on the analysis point of view, the Liouville Numbers has null measure, considering the Lebesgue and Hausdorff measures.</p> Anderson Luiz Maciel, Juan Manuel Silva Fervenza Copyright (c) 2022 Ciência e Natura Thu, 07 Jul 2022 00:00:00 -0300
