Transmission line towers are highly exposed to weather hazards. In southern Brazil, several damages to transmission lines have been reported due to severe weather events. Climate change projections indicate that the frequency and magnitude of extreme events may increase, making planning and adaptation of the transmission system exposure even more critical. In this work, we propose a severe weather index (SWI) as a proxy for detecting severe storms that can potentially result in extreme weather events. The SWI combines thresholds of instability indices based on observed severe events around the transmission tower-line systems. These indices were calculated using the downscaling by the Eta model at 20 km resolution of three global climate model projections and at 5 km of one global climate model for the historical period and the near future. The results show that the SWI captures the severe storms observed in the region. All downscaling projections agree with the increase of extreme weather events in the near future and the expansion of vulnerable areas. The constructed index can be employed to assess the risks and to plan the power transmission system better.

As indústrias da construção civil e do agronegócio buscam processos e produtos que necessitem de uma menor quantidade de energia na sua fabricação. Diversos resíduos oriundos dos segmentos citados são aproveitados como fundentes, ligantes, aditivos, etc. evitando o descarte in natura. A cinza do bagaço da cana-de-açúcar (CBC) e o resíduo de cerâmica vermelha (RCV) são passivos que, isoladamente, apresentam potencial pozolânico. Quando misturados, poderão gerar novos silicatos e aluminatos de cálcio hidratados, decorrentes da recombinação da sílica e alumina amorfas existentes em sua composição com a fase Portlandita, advinda da hidratação do cimento e da constituição química da cal hidratada. A pesquisa avaliou a viabilidade do uso combinado desses resíduos como aditivo pozolânico na moldagem de tijolos maciços de solo-aglomerante(s), sem e com teores de 2% e 4% de RCV e 2% de CBC. Foi realizada a caracterização física, química e mineralógica dos insumos e, em seguida, a moldagem dos tijolos. Amostras dos melhores resultados foram submetidas aos ensaios de DRX e MEV. As composições S12C4RCV e S12C2CBC2RCV, em relação às propriedades físicas e mecânicas, atingiram os melhores resultados.

The banking industry has been employing artificial intelligence (AI) technologies to enhance the quality of its services. More recently, AI algorithms, such as natural language understanding (NLU), have been integrated into chatbots to improve banking applications. These chatbots are typically designed to cater to customers’ needs. However, research in the development of troubleshooting chatbots for technical purposes remains scarce, especially in the banking sector. Although a company may possess a knowledge database, a standard methodology is essential to guiding an AI developer in building a chatbot, making the modeling of technical needs into a specialized chatbot a challenging task. This paper presents a novel methodology for developing troubleshooting chatbots. We apply this methodology to create an AI-powered chatbot capable of performing technical ATM maintenance tasks. We propose the TroubleshootingBot, an experimental protocol to obtain data for evaluating the chatbot through two scenarios. The first scenario detects user intent, and the second recognizes desired values in a user’s phrase (e.g., three beeps or two beeps). For these scenarios, we achieved accuracies of 0.93 and 0.88, respectively. This work represents a significant advancement in virtual assistants for banking applications and holds potential for other technical problem-solving applications.

Sufficiency measures are potentially decisive for the decarbonisation of energy systems but rarely considered in energy policy and modelling. Just as efficiency and renewable energies, the diffusion of demand-side solutions to climate change also relies on policy-making. Our extensive literature review of European and national sufficiency policies fills a gap in existing databases. We present almost 300 policy instruments clustered into relevant categories and publish them as "Energy Sufficiency Policy Database". This paper provides a description of the data clustering, the set-up of the database and an analysis of the policy instruments. A key insight is that sufficiency policy includes much more than bans of products or information tools leaving the responsibility to individuals. It is a comprehensive instrument mix of all policy types, not only enabling sufficiency action, but also reducing currently existing barriers. A policy database can serve as a good starting point for policy recommendations and modelling, further research is needed on barriers and demand-reduction potentials of sufficiency policy instruments.

Abstract Background Most of our understanding on the social behavior and genomics of bees and other social insects is centered on the Western honey bee, Apis mellifera. The genus Apis, however, is a highly derived branch comprising less than a dozen species, four of which genomically characterized. In contrast, for the equally highly eusocial, yet taxonomically and biologically more diverse Meliponini, a full genome sequence was so far available for a single Melipona species only. We present here the genome sequence of Frieseomelitta varia, a stingless bee that has, as a peculiarity, a completely sterile worker caste. Results The assembly of 243,974,526 high quality Illumina reads resulted in a predicted assembled genome size of 275 Mb composed of 2173 scaffolds. A BUSCO analysis for the 10,526 predicted genes showed that these represent 96.6% of the expected hymenopteran orthologs. We also predicted 169,371 repetitive genomic components, 2083 putative transposable elements, and 1946 genes for non-coding RNAs, largely long non-coding RNAs. The mitochondrial genome comprises 15,144 bp, encoding 13 proteins, 22 tRNAs and 2 rRNAs. We observed considerable rearrangement in the mitochondrial gene order compared to other bees. For an in-depth analysis of genes related to social biology, we manually checked the annotations for 533 automatically predicted gene models, including 127 genes related to reproductive processes, 104 to development, and 174 immunity-related genes. We also performed specific searches for genes containing transcription factor domains and genes related to neurogenesis and chemosensory communication. Conclusions The total genome size for F. varia is similar to the sequenced genomes of other bees. Using specific prediction methods, we identified a large number of repetitive genome components and long non-coding RNAs, which could provide the molecular basis for gene regulatory plasticity, including worker reproduction. The remarkable reshuffling in gene order in the mitochondrial genome suggests that stingless bees may be a hotspot for mtDNA evolution. Hence, while being just the second stingless bee genome sequenced, we expect that subsequent targeting of a selected set of species from this diverse clade of highly eusocial bees will reveal relevant evolutionary signals and trends related to eusociality in these important pollinators.

Tracking progress towards the Paris Agreement climate goal requires understanding the 2030 emission levels implied by countries’ National Determined Contributions (NDCs). However, key uncertainties and assumptions impact greenhouse gas (GHG) emission projections implied by the NDCs. This study analyses this impact, both globally and for major emitting countries. We find that the assessed uncertainties markedly affect global GHG emission projections. Full achievement of NDC targets is estimated to result in a range of 46–60 GtCO _2 eq by 2030 (median estimate: 53 GtCO _2 eq). The uncertainty in measuring historical emissions, including land-use, as reflected by different datasets is the most important contributing factor. This is followed by two equally important factors globally: socio-economic baseline uncertainty and uncertainty about the emissions implied by current policies in case NDCs are less ambitious than these. Overall, the impact of policy uncertainty (i.e. uncertainty resulting from conditionality of or ranges in NDC targets and uncertainty in emissions resulting from current policies) is about equally important as model/technical uncertainty (i.e. uncertainty in historical emissions and socio-economic baseline variations). This new insight is important for decision makers and researchers because a larger share of the total uncertainty is now attributable to aspects that can be influenced by policy decisions compared to previous analyses of NDC uncertainty.

Neste artigo analisaremos o papel do livro didático enquanto instrumento de propagação e consolidação de representações, mais especificamente das representações acerca do negro nos livros de história regional. Com esse propósito, após apresentarmos a permanência de uma tendência preconceituosa e estereotipada nos livros didáticos brasileiros nos séculos XIX e XX, optamos por verificar se essas mesmas tendências foram reiteradas nos livros escolares de história do Espírito Santo publicados no período de 1964 até 1997. Com o desenvolvimento da pesquisa, constatamos que, apesar da permanência de uma escrita eurocêntrica, os livros produzidos por autores capixabas apresentaram, em diversos momentos, o negro como agente ativo na história local, mesmo antes da existência de uma legislação que assim os exigisse, e a frente inclusive de uma tendência nacional.

As aproximações entre a História e a Antropologia permitiram nas últimas décadas uma transformação nos estudos sobre a história indígena deslocando as representações daqueles indivíduos enquanto vítimas e coadjuvantes para o papel de agentes ativos no processo de colonização da América Portuguesa. À luz do que há de mais recente nas produções historiográficas propomos analisar como os interesses de Goitacazes, Temiminós, portugueses e franceses construíram, destruíram e reelaboraram as inimizades ou alianças estabelecidas entre estes sujeitos no litoral sul da capitania do Espírito Santo no século XVI.

O presente artigo tem como objetivo apresentar a constituição da imagem pública do atual deputado federal Jair Bolsonaro a partir das pautas políticas associadas a ele em 30 anos de matérias jornalísticas. Foram utilizadas matérias de 1987 a 2017 veiculadas por dois jornais impressos de alcance nacional: a Folha de S. Paulo e O Estado de S. Paulo. Ao longo dos diferentes cargos políticos que ocupou, de que maneira seus posicionamentos dentro do debate político foram sendo apresentados a uma infinidade de leitores? Seria possível percebermos algum tipo de continuidade e/ ou alteração de pautas, indicando – ou não – certa “coerência” política? Quais seriam estes posicionamentos ou pautas? Estas são algumas das questões que animaram este trabalho. Na primeira seção do artigo serão feitas algumas ponderações teórico-metodológicas sobre as fontes utilizadas para a compreensão da natureza e do alcance dos nossos dados. Em seguida, apresentamos as técnicas e os métodos empregados, bem como o processo de coleta e caracterização dos dados. A terceira seção descreve a construção das categorias de análise utilizadas. A quarta e última sessão é composta pelos resultados qualitativos e quantitativos obtidos permeados por reflexões sobre as pautas políticas mais recorrentes nas matérias.

Os discursos estão intrinsecamente ligados às relações socioculturais e ideológicas, não existem fora delas e, portanto, não podem ser analisados fora delas. Somos atravessados por formações discursivas que nos constituem como sujeitos. As formações discursivas são conjuntos de discursos atravessados por regimes de verdade que legitimam sistemas institucionais e corporais de dominação e exclusão. A sexualidade é um campo interditado e normalizado por diferentes discursos. Cabe, então, a seguinte indagação: Como operam as formações discursivas, atravessadas pelo discurso religioso-fundamentalista cristão, que interditam e normalizam a sexualidade? Para refletir sobre essa indagação, proponho analisar e desconstruir uma dada formação discursiva atravessada pelos discursos religioso-fundamentalista cristão e político-jurídico: refiro-me à “cruzada” empreendida nas vésperas da aprovação do Plano Nacional de Educação (PNE), em 2014, por deputados conservadores, mobilizados por fundamentalistas cristãos dentro e fora do campo da representação política, contra o que foi definido como “ideologia de gênero”. Esse (pre)conceito gerou ecos que infelizmente permanecem latentes, razão pela qual me proponho a fazer tal análise.

O presente artigo investiga, mediante estudo de caso, o impacto do consumo de conteúdos divulgados pelos Núcleos Estaduais de Orquestras Juvenis e Infantis da Bahia (NEOJIBA) em suas redes sociais, na pandemia. Logo, constatou-se a hipótese de que, no cenário em questão, a utilização frequente das plataformas digitais vem assegurando ao público uma forma inédita de fruição dessas publicações. Visando a elucidar tal teoria, foram analisados o engajamento e o alcance das postagens publicadas em maio de 2021 nos canais do NEOJIBA no Instagram e no YouTube. Além disso, este trabalho evidencia um panorama sucinto das orquestras, bem como estabelecer um paralelo entre elas e sua presença hoje recorrente nos meios digitais. A conclusão é que os entusiastas de música erudita vêm consumindo em potencial os conteúdos hospedados nas redes do programa.
