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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/63576 Mon, 02 May 2022 00:00:00 -0300 Flood risks in regularized watersheds: Case study of the flood in the Mondego River, Portugal https://periodicos.ufsm.br/cienciaenatura/article/view/63586 <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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/63586 Tue, 26 Apr 2022 00:00:00 -0300 Hydrological modelling applied to flooding assessment in the urban coastal city in Brazil https://periodicos.ufsm.br/cienciaenatura/article/view/67163 <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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/67163 Mon, 09 May 2022 00:00:00 -0300 Titanium dioxide nanoparticles promote histopathological and genotoxic effects in Danio rerio after acute and chronic exposures https://periodicos.ufsm.br/cienciaenatura/article/view/67963 <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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/67963 Mon, 23 May 2022 00:00:00 -0300 Briology studies in the northern region https://periodicos.ufsm.br/cienciaenatura/article/view/41276 <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? For data collection, we used the databases SCIELO, Google Scholar and sucupira platform. The inclusion criteria were defined as articles published between 1988 and 2018, and the exclusion criteria were articles from those 30 years old that were not located. States outside the northern region were excluded. Over the last 30 years, there were 186 scientific works, of which 58 articles were analyzed. Advances in Bryophyta research in the northern region are linked only to Brioflora's urban centers and surveys, so knowledge of the entire region is required for use in different areas of science.</p> Larissa de Souza Saldanha, Osvanda Silva de Moura, Renato Abreu Lima Copyright (c) 2022 Ciência e Natura http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/41276 Mon, 02 May 2022 00:00:00 -0300 Water and Sewage in prospect of Sustainable Logistics Management Plan: An analysis of Brazilian Federal Universities practices https://periodicos.ufsm.br/cienciaenatura/article/view/67534 <p>The Sustainable Logistics Management Plan ruled by Decree 7,746/2012 and by Normative Instruction. 10/2012, is a planning instrument that aims to change the organs and entities connected to the Federal Public Administration policy faced to Water and Sewage good practices. Those rules state that each public bodies must present the Action Plan followed the respective Monitoring Reports. Thus, this article aimed to evaluate the Water and Sewage policies applied on the 63 Brazilian Federal Universities Plan. The methodology implied an exploratory and descriptive study, with a qualitative approach, based on documentary analysis, accomplished through content analysis. The results pointed to relative adherence of the Brazilian Federal University to the Plan, as long as thirty and five published their Action Plans and eighteen of them revealed the correspondent Monitoring Reports. The results show that, even being a federal law, the Plan has not reached its goal yet on Brazilian Federal University on Water and Sewage policy.</p> Kemerson Cantero Campos, Rosamaria Cox Moura-Leite, José Carlos de Jesus Lopes, Jeovan de Carvalho Figueiredo, Erlaine Binotto Copyright (c) 2022 Ciência e Natura http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/67534 Wed, 29 Sep 2021 00:00:00 -0300 Reverse logistics in gas stations in the metropolitan region of Curitiba (Brazil) https://periodicos.ufsm.br/cienciaenatura/article/view/67672 <p>The National Solid Waste Policy (PNRS) established by Law 12,305/2010, mentions Reverse Logistics (RL) as a development tool for the return of the production cycle, and also presents instruments for shared responsibility for the life cycle of products. The RL of lubricating oils in post-consumption and return is linked to concern for the environment and sustainability in the business sphere. 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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/67672 Wed, 29 Sep 2021 00:00:00 -0300 Geotechnologies for the assessment of environmental conflicts in the Vacacaí-Mirim river sub-basin https://periodicos.ufsm.br/cienciaenatura/article/view/66982 <p>The degradation of forests is a process that has intensified over time due to human activities such as agricultural expansion, livestock and urbanization, causing numerous damages to ecosystems and, consequently, to human beings. Spatial analysis, through the use of geotechnologies, allows monitoring and obtaining information about natural and man-made phenomena that occur on the Earth's surface, with low cost and remotely. Such information can assist managers in making decisions about important resources essential to life and ecological balance, including water. Thus, the objective of this study was to determine the areas along water courses and in the vicinity of water springs that presented conflict with the environmental legislation in the hydrographic sub-basin of the Vacacaí-Mirim River, in the year 2020, by means of geoprocessing and remote sensing techniques. For this, a high-resolution image fusion technique was used to CBERS 04A satellite high-definition images, generating a false-color composition, where environmental conflicts were identified and quantified in the Permanent Preservation Areas (APP) of the studied water courses resources. The results showed the existence of land use conflicts in 29.23% of the Permanent Preservation Areas (APP) over the studied water courses and in 31.4% of the APP around the water springs.</p> Ariel Cezar Teixeira, Maurício Rizzatti Copyright (c) 2022 Ciência e Natura http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/66982 Mon, 25 Apr 2022 00:00:00 -0300 Some properties of the set of Liouville numbers https://periodicos.ufsm.br/cienciaenatura/article/view/65058 <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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/65058 Mon, 18 Apr 2022 00:00:00 -0300 Biodiversity in urban centers: knowing and acknowledging palm trees in Antônio Danubio Park https://periodicos.ufsm.br/cienciaenatura/article/view/43748 <p>The green areas conservation in urban perimeters is an effective way to maintain native plant species, in addition to the important socio-environmental role they play in cities. Parque Antônio Danúbio is a conserved forest fragment in the metropolitan area of Belém, Pará, which presents a great diversity of native flora species, especially palm trees. The present study objective was to carry out a survey of the palm trees in Parque Antônio Danúbio aiming to know the vegetation structure through the distribution and frequency of the registered species. The study was made using a qualitative approach, frequency and structure analyzes (height classes) were also carried out. Nine palm species were identified, being açaí (<em>Euterpe oleracea</em> Mart.), mumbaca (<em>Astrocaryum gynacanthum</em> Mart.) and bacaba (<em>Oenocarpus bacaba</em> Mart.) the most frequent. Individuals distribution in the height classes indicated that there is regeneration in the environment. Such results show that Parque Antônio Danúbio presents a representative diversity of native palm trees, and the populations of these species enjoy good conditions for their development.</p> <h5 style="user-select: text;"> </h5> Karina de Nazaré Lima Alves, Flávia Cristina Araújo Lucas, Maria Antonia Ferreira Gois Copyright (c) 2022 Ciência e Natura http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/43748 Tue, 03 May 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 https://periodicos.ufsm.br/cienciaenatura/article/view/64753 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 article was constructed having a research question defined ex-ante, elaborated based on the literature, where a research protocol adapted from Tranfield, Denyer, and Smart (2003) was systematized according to the methodological rigor demanded in the literature review, which resulted in the composition of the research corpus. The research corpus was evaluated in detail using the bibliometric packages HistCite, VOSviewer, package R and Iramuteq. It was evaluated the validity of the 3 bibliometric laws were verified: Lotka's Law, Bradford's Law, and Zipf's Law based on the authors’ citation and co-citation techniques. This study is considered as relevant and original since it is the first literature review on control charts for autocorrelated processes. The results confirmed the 3 classical bibliometric laws for the researched corpus. As a practical implication, this review provides support for quality management scholars to unlock potential research gaps. The main limitation of the work refers to the composition of the textual corpus, given that databases of national journals were not consulted due to the difficulty in terms of compatibility of the software used in this research.</p> Valentina Wolff Lirio, Tailon Martins, Bianca Reichert, Gilvete Silvania Wolff Lirio, Adriano Mendonça Souza, Wesley Vieira da Silva Copyright (c) 2022 Ciência e Natura http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/63150 Mon, 02 May 2022 00:00:00 -0300 Precipitation schemes by quantile technique and its water balances in Barbalha - CE, Brazil https://periodicos.ufsm.br/cienciaenatura/article/view/64696 <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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/64696 Mon, 02 May 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 https://periodicos.ufsm.br/cienciaenatura/article/view/66169 <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 http://creativecommons.org/licenses/by-nc-sa/4.0 https://periodicos.ufsm.br/cienciaenatura/article/view/66169 Mon, 02 May 2022 00:00:00 -0300
