Revitalização da biblioteca de uma escola municipal: possibilidade de usos de resíduos descartáveis como ferramentas pedagógicas

Dentre os problemas ambientais que afetam a população está o não gerenciamento dos resíduos sólidos. No Brasil, em 2022, 39% destes não receberam destinação adequada. Dar uma finalidade econômica, correta e sustentável para os resíduos ainda é um desafio. O objetivo deste projeto foi identificar a potencialidade didática da utilização de resíduos sólidos urbanos (RSU) na revitalização da biblioteca de uma escola de educação básica do município de Canoinhas-SC, para fomentar a consciência sustentável por meio de uma ação de extensão do protagonismo discente ofertada pelo Instituto Federal de Santa Catarina campus Canoinhas. A ação mostra a importância da curricularização da extensão e foi dividida em cinco etapas: levantamento bibliográfico acerca do tema, levantamento das necessidades da biblioteca a ser revitalizada, elaboração do projeto de revitalização, produção dos mobiliários utilizando RSU e revitalização do espaço

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Suscetibilidade a escorregamentos e inundações: hierarquização dos graus de riscos na área urbana de Viçosa-MG

A identificação das áreas de risco é um importante instrumento para gestão das políticas públicas. Desse modo, esse trabalho objetivou hierarquizar as áreas de riscos a escorregamentos e inundações na área urbana do município de Viçosa, Minas Gerais, através de técnicas de Geotecnologias. Utilizou-se a metodologia de Álgebra de Mapas através da distribuição de ponderação para os mapas de Uso e Cobertura da Terra, Declividade e Compartimentação Geomorfológica, efetivando a soma/multiplicação desses fatores e de suas classes resultando em três graus de riscos: Grau 1 (Baixo Risco), Grau 2 (Médio Risco) e Grau 3 (Alto Risco). Assim, concluiu-se que, além das classificações de Médio e Baixo Risco, cerca de 60% da área urbana de Viçosa é considerada de Alto Risco para escorregamentos e 24% para inundações. A utilização das geotecnologias como embasamento metodológico apresentou viabilidade para planejamentos voltados a mitigação e prevenção de desastres naturais em áreas urbanas

Análise morfométrica das sub-bacias de 3ª ordem da bacia hidrográfica do Rio do Peixe, Minas Gerais

A morfometria é fundamental para o entendimento da dinâmica ambiental de uma determinada área. A análise morfométrica e morfológica em bacias hidrográficas visa o compreendimento do modelado do relevo e da dinâmica fluvial local e regional e, através da aplicação de parâmetros morfométricos, pode-se avaliar quantitativamente o comportamento dessas unidades. A bacia hidrográfica do rio do Peixe, situada no sudeste do estado de Minas Gerais, Brasil, apresenta em seu território especificidades morfométricas quando comparada às áreas circunvizinhas e, com o intuito de investigar essas características morfométricas, este trabalho teve como objetivo compreender e explicar, embasado metodologicamente em interpretações geomorfológicas e morfométricas, a heterogeneidade do modelado das sub-bacias, de terceira ordem, que compõem a porção sul da bacia hidrográfica do rio do Peixe. Para espacialização dos resultados dos cálculos dos parâmetros morfométricos, foram gerados mapas temáticos que auxiliaram nas interpretações comparativas. Após análise dos resultados pôde-se concluir que as singularidades constatadas (expressivos lineamentos estruturais, controle litológico, variação litológica, rupturas de declive e zonas de cisalhamento) ao norte e ao oeste da porção sul da bacia hidrográfica do rio do Peixe podem ter relação com a variação litológica e também altimétrica.La morphométrie est fondamentale pour comprendre la dynamique environnementale d'une zone donnée. L'analyse morphométrique et morphologique dans les bassins versants vise à comprendre la modélisation du relief et la dynamique fluviale locale et régionale et, grâce à l'application de paramètres morphométriques, il est possible d'évaluer quantitativement le comportement de ces unités. Le bassin de la rivière Preto situé au sud-est de l'état de Minas Gerais, au Brésil, présente sur son territoire des spécificités morphométriques par rapport aux zones environnantes. Pour étudier ces caractéristiques morphométriques, ce travail visait à comprendre et à expliquer méthodologiquement, basé sur des interprétations géomorphologiques et morphométriques, l'hétérogénéité de modélisation des sous-bassins de deuxième ordre, qui constituent la partie sud du bassin versant de la rivière Peixe. Pour la spatialisation des résultats des calculs des paramètres morphométriques, des cartes thématiques ont été générées qui ont aidé dans les interprétations comparatives. Après analyse des résultats, il a été possible de conclure que les singularités trouvées (linéaments structuraux expressifs, contrôle lithologique, variation lithologique, ruptures de pente et zones de cisaillement) au nord et à l'ouest de la partie sud du bassin versant de la rivière Peixe peuvent être liées à la variation lithologique et altimétrique.Morphometry is fundamental for understanding the environmental dynamics of a given area. The morphometric and morphological analysis in watersheds is aimed at understanding the modeling of relief and local and regional fluvial dynamics and, through the application of morphometric parameters, the behavior of these units can be quantitatively evaluated. The watershed of the Peixe river, located in the southeast of the state of Minas Gerais, Brazil, presents in its territory morphometric specificities when compared to surrounding areas and, in order to investigate these morphometric characteristics, this work had the objective of understanding and explaining, methodologically based In geomorphological and morphometric interpretations, the heterogeneity of the modeling of the third-order sub-basins that make up the southern portion of the Peixe river basin. For the spatialization of the results of the calculations of the morphometric parameters, thematic maps were generated that aided in the comparative interpretations. After analyzing the results it was possible to conclude that the singularities found to the north and west of the southern portion of the catchment area of ​​the Peixe River may be related to the lithological and altimetric variation

Influence of Primekote® polymer in orthodontic bonding

Abstract Objective The Primekote® (TP) polymer was incorporated to the of Orthodontic Bracket mesh base to improve bond strength and make it more efficient. The purpose of this study was to assess the shear bond strength and adhesive remnant index (ARI) of these brackets. Material and method The test sample consisted of thirty bovine incisors divided into 2 groups: with a group with TP® brackets (n=15), and a control group with Morelli® brackets (n=15) without Primekote® technology. The TransbondTM XT was used as adhesive system in both groups, following the same protocol and manufacturer’s instructions. Specimens were stored in distilled water for 24 hours and then submitted to shear bond strength test in a universal testing machine (EMIC DL2000). The assessment of ARI was performed under stereomicroscope by two calibrated examiners. Result No significant differences (p>0.05) in shear bond strength were found between the two groups according to the independent t-test. The Wilcoxon test was used to assess ARI data and statistical difference was found between Morelli® and TP® Nu-Edge brackets; the last one left less remaining adhesive on tooth surface. Conclusion TP® brackets had higher adherence to the adhesive system as shown by lower ARI scores, but this does not improve its clinical performance
