Predicting Rubberized Concrete Compressive Strength Using Machine Learning: A Feature Importance and Partial Dependence Analysis
Authors: Hasanipanah Mahdi , Abdullah Rini Asnida , Iqbal Mudassir , Hai-Bang Ly
Published: August 2023

Rubberized concrete is a material that is both ecologically friendly and sustainable, and it has been finding more and more usage in building applications recently. In this study, a machine learning model, namely LightGBM, is developed to predict the compressive strength (CS) of rubberized concrete using 11 input parameters. The performance of the model is measured using a number of different statistical criteria after it has been trained on a dataset containing 275 samples. In order to evaluate the impact that each input parameter has on the CS, feature importance and partial dependency plots (PDP) are used as analytical tools. According to the findings, the superplasticizer, chipped rubber, crumb rubber, coarse aggregate, fine aggregate, and water content all have a significant impact on the CS of rubberized concrete. On the other hand, the results indicate that the cement content, slag/fly ash content, and type of CS have a relatively minor effect. In addition to this, the PDP offers insights into the manner in which the input parameters have an effect on the CS of rubberized concrete. Overall, the developed model and analytic techniques may be used as a helpful tool in forecasting the CS of rubberized concrete and improving its mix design for a variety of construction applications.

Published: August 2023

In this research, Molecular Dynamics (MD) simulations were conducted to explore the temperature effect on the microstructure and phase transition of the Ag0.25Au0.75 alloy. The findings reveal that as the temperature rises, the material's phase transition switches from crystalline to liquid and vice versa. Notably, during the phase transition, significant changes occur in the link length (r), the total energy of the system (Etot), and the number of structural units FCC, HCP, BCC, and Amor. The microstructural features of the models were analyzed using the radial distribution function (RDF), a number of structural units, shape, size (l), and total energy of the system (Etot). In addition, the length of the link Ag-Ag, Ag-Au, Au-Au, the size of the material has a very small change value and is considered almost constant, and the height of the radial distribution function (RDF) decreases. The number of structural units FCC, HCP decreased, BCC, Amor increased, and the total energy of the system increased, thereby confirming that the influence of temperature on the microstructure and phase transition of the Ag0.25Au0.75 alloy is very large. Besides, the micro-structural characteristics of the Ag0.25Au0.75  alloy can be applied as a basis for future experimental studies.

Interpreting Ratification
Authors: Coan Andrew , Schwartz David S.
Published: August 2023

For two centuries, constitutional interpreters have relied on statements from the ratification debates—especially The Federalist—as persuasive authority in constitutional interpretation. This reliance, which has only increased with the rise of public-meaning originalism, mistakes Federalist campaign literature and oratory for objective and disinterested constitutional interpretation, and mistakenly dismisses the interpretations of Anti-Federalists as irrelevant. Focusing on the debate over enumerated powers, this article challenges the unfounded assumptions of Federalist objectivity and Anti-Federalist irrelevance and models the historical method necessary to interpret the ratification debates rigorously. More specifically, the article advances three central claims. First, the probable insincerity of much Federalist advocacy—including The Federalist—significantly undercuts its authority as evidence of a determinate original public meaning. Second, Anti-Federalist advocacy opposing ratification is much more probative evidence of original public meaning than has generally been recognized. Third, the most prominent arguments for privileging Federalist over Anti-Federalist advocacy are internally flawed and historically unfounded. More important, none of those arguments can be squared with the tenets of public-meaning originalism. All of this significantly undermines a principled originalist case for limiting federal power. It also calls into question the resolving power of originalism as a practical method for deciding controversial cases. Both of these implications would represent seismic shifts in U.S. constitutional law.

Impact de la pandémie à coronavirus sur les prix des produits de première nécessité et politiques macroéconomique subséquentes
Authors:   CRSH, Kabungu Bobo
Published: August 2023

La République Démocratique du Congo subit l’impact de la crise sanitaire liée à la propagation du coronavirus à deux niveaux : (i) sur le plan international, les mesures de précaution de santé ont imposé la fermeture de plusieurs usines suivie de celle des frontières, paralysant le commerce international ; (ii) sur le plan intérieur, le Gouvernement a opté pour le confinement du centre de la capitale, la suspension des activités de l’industrie du divertissement et de la restauration et la limitation de la circulation des personnes, y compris entre provinces. Ce choc n’est pas sans conséquences. Pour la première fois depuis près de 20 ans, le pays enregistrera une décroissance économique du fait de l’arrêt de l’appareil productif (-2,4 %). Dans ce contexte, les prix des biens et services, principalement des produits de première nécessité, s’envolent notamment à cause d’une demande excédent l’offre, laquelle est, par ailleurs, principalement alimentée par l’importation. Cette réalité est vécue dans la quasi-totalité des pays africains. Face à cette situation, il importe d’actionner des politiques conjoncturelles et structurelles à cibler.
Le droit à la liberté de circulation des personnes à l’épreuve des mesures de lutte contre la pandémie de la Covid-19 en RDC
Authors:   CRSH, Kamunga Ngalula Jimmy
Published: August 2023

The Covid-19 pandemic is an unprecedented threat to health. Like other States, the DRC has taken unprecedented and exceptional measures to fight the outbreak of the virus and preserve human lives. These measures have restricted several human rights and fundamental freedoms, in addition to revealing a conflict between the right to protection of health and the right to freedom of movement, both fundamental and essential to the development of the person. However, taken in accordance with the Constitution and with the aim of protecting public health and the life of the population, measures restricting freedom of movement are disproportionate to the health risks. They have given rise to alarming consequences for a poor population deprived of the means of daily survival and social security, and ignore the principle of the indivisibility of human rights.
Titre : L’évaluation des politiques publiques comme créneau de recherche des «prix nobel 2019 d’économie» Quels enseignements institutionnels pour la RDC ?

Published: August 2023

The awarding of a Nobel Prize allows its holder to enjoy a notoriety that sheds a brighter light on his research or his activity. While several foreign media and numerous researchers have returned to the contribution of the 2019 winners in terms of scientific “discoveries” and/or their commitment to evaluation in the service of development, the subject did not hold as much attention. attention neither in the press nor in the specialized journals in the DRC. This reflection proposes to fill, however slightly, this informational deficit and to launch, in the arena of objectivity, the debate of ideas on the evaluation of the interventions of the public authorities. It should be mentioned that the analysis which had been launched at the time in a tabloid, in the form of a forum, attracted the attention of several readers and their reactions led to the deepening of the subject. The paper summarizes the profile of the laureates, dwells on the evaluation of public policies as a field of research, with a critical look at experimental methods, and leads to direct and indirect institutional lessons for the DRC.
The language of muteness: examining the work of Gazdanov and Salkazanova in Paris
Authors: Salbiev Tamerlan K.
Published: August 2023

The article examines the principles and methods of constructing discourse that emerges through a unique combination of socio-cultural and linguistic factors in the context of a European metropolis. Participants involved are representatives of the first and second wave of Russian emigration: Gaito (Georgy Ivanovich) Gazdanov, a prominent writer of the Russian diaspora, and Fatima Salkazanova, an aspiring journalist who crossed paths with Gazdanov in the 1960s in Paris while working in the Russian service of Radio Liberty[60]. Salkazanova's oral memoirs provide valuable insights, revealing that Gazdanov remained completely silent in her presence for a period of six months until he unexpectedly spoke to her, advising her to purchase a new watch. The primary focus of this study is to elucidate the strategy employed in constructing this ‘wordless’ discourse, as well as to explore the conditions that facilitate its occurrence, underlying mechanisms, and its historical background. The analysis encompasses linguistic, historical, cultural aspects, and aims to determine its linguistic classification and overall significance. The discourse itself is interpreted as a revival of the archaic ritual of silence practiced in Ossetian patriarchal families, serving as a form of speech etiquette. This relic language practice, rooted in Indo-European archaic traditions, represents a manifes­ta­tion of the rite of passage and allows individuals of Ossetian origin, who may have lost their na­tive language due to external circumstances, to demonstrate their cultural identity. It is suggested that the occurrence of such speech behaviour is strongly influenced by the specific time and place, where forced emigration to Europe not only contributes to the preservation of archaic speech etiquette patterns but also involuntarily activates them.
What is a ‘rare’ language in translation? The experience of distance reading
Authors: Bochaver Svetlana Yu. , Tereshko Ekaterina V.
Published: August 2023

This article examines the perception of ‘rare’ and ‘common’ languages through literary translations. The study is based on the materials from De Bezige Bij Publishing House in the Netherlands, comparing the periods of 2010—2013 and 2020—2023. A significant increase in the role of translators is reflected in the rise of translation share in the publishing house. There is an observed growth in the number of source languages for translation, with a dec­rease in the proportion of English. Translations from French, Italian, German, Scandinavian languages, Portuguese, and Japanese have emerged. A comparison with the Polyandria Rus­sian Publishing House during the period of 2020—2023 reveals common and distinct source lan­guages. Both publishers translate literature into Danish, Finnish, and French to a similar extent. The Russian publishing house represents Norwegian and Japanese to a greater extent, while the Dutch publishing house releases more translations from German, Swedish, Turkish, and Italian. The Russian publisher also includes Icelandic, Albanian, Korean, and Croatian, while the Dutch publisher includes Hebrew, Romanian, and Portuguese. Both publishers en­com­pass a total of 20 source languages, which is a small number compared to the global lin­guistic diversity. Comparing the volumes of source languages also indicates diffe­ren­ces in pre­ferences. Central European languages are chosen in the Netherlands, while Nor­wegian and Ice­landic are favored in Russia. These differences may be influenced by the cost of rights to works, editorial preferences, and translator availability. The analysis results indicate that neither typological similarity between the source language and the target language, nor association with a specific language group, influences the preference for translating books from a particular language. This highlights the importance of sociocultural factors.

A industrialização proporcionou novos modos de produção, entre eles a siderurgia, possibilitando a evolução do mundo como é conhecido hoje, mas também impactos negativos causados ao meio ambiente e à qualidade de vida da população. O objetivo desta pesquisa consistiu em verificar o impacto socioambiental de um empreendimento siderúrgico em um município sul-mato-grossense – particularmente numa região conhecida como portal do pantanal – na perspectiva dos moradores do seu entorno. Trata-se de uma pesquisa com abordagem quantitativa e qualitativa, descritiva e exploratória e de levantamento (Survey). Houve interrogação aos moradores do mesmo bairro onde se localiza o empreendimento siderúrgico, com o apoio da aplicação de um questionário, com perguntas predominantemente fechadas cujos dados foram, em sua maioria, analisados com análise descritiva por frequência. Os principais impactos socioambientais são a poluição sonora e do ar, o prejuízo na saúde e a contaminação do solo e da água. O estudo apresenta sugestões para o empreendimento e para futuras pesquisas como a verificação clínica da saúde dos moradores e análise laboratorial do solo.

SISTEMA AQUÍFERO PARECIS: VULNERABILIDADE NATURAL E RISCO À CONTAMINAÇÃO
Authors: Backes Elizete Marley , Migliorini Renato Blat
Published: August 2023

Os métodos de vulnerabilidade de aquíferos são muito utilizados para mapear áreas suscetíveis à contaminação, servindo de ferramenta para a gestão dos recursos hídricos subterrâneos. Esta pesquisa visa avaliar a vulnerabilidade natural pelo método MAIA (Método de Avaliação Intrínseca de Aquíferos) e o risco à contaminação do Sistema Aquífero Parecis (SAP) no Estado de Mato Grosso. Este método é uma nova proposta entre as diversas metodologias existentes e se destaca por utilizar apenas variáveis passíveis de serem medidas nos poços ou nos aquíferos como a profundidade da água subterrânea, capacidade específica de poços, transmissividade do aquífero, espessura do solo, declividade do terreno e a pluviosidade média anual, eliminando a subjetividade inerente aos processos de avaliação até então aplicados. Os índices de vulnerabilidade calculados pela equação MAIA resultaram em 96% dos poços classificados como de média vulnerabilidade, 3% de baixa e 1% de alta e extrema vulnerabilidades. Os fatores que mais influenciaram nos resultados de alta e extrema vulnerabilidades foram a pouca profundidade do nível da água, a alta capacidade específica dos poços e o valor elevado de chuvas médias anuais combinadas com a pouca declividade do terreno, favorecendo a infiltração da água no solo e podendo carrear eventuais contaminantes.

O estudo objetivou propor um método de valoração para o Pagamento por Serviços Ambientais Hídricos (PSA-H) na zona de amortecimento (ZA) do Parque Estadual da Lapa Grande (PELG), no semiárido mineiro. Para isso, construiu-se uma base de dados para coletar e organizar informações de iniciativas de PSA-H do Sudeste brasileiro. As iniciativas foram analisadas conforme categorias e atributos, subsidiando uma proposta metodológica de valoração ambiental de PSA-H. Verificou-se que apesar das iniciativas de PSA-H estarem na mesma região e terem objetivos semelhantes, os métodos de valoração são diferentes, variando segundo os tipos de intervenção adotados. Para a valoração, foi selecionado, adaptado e calculado o valor pelo serviço ambiental de provisão de água, resultando em R$ 59,07/ha/ano. Com a aplicação do método de valoração escolhido, o pagamento variou entre R$ 0,15 e 50,29/ha/ano, para modalidade III, de conservação de remanescentes de vegetação nativa. Os valores foram baixos se comparados a outras iniciativas de PSA-H semelhantes.

Neste sentindo, o presente estudo tem objetivo de analisar os parâmetros microbiológicos e parasitológicos das águas do açude São Vicente, que está localizado no município de Santana do Acaraú — CE, e compará-los com os parâmetros estabelecidos pela legislação vigente do Ministério da Saúde. Os métodos utilizados para se chegar a tais fins foram o método dos tubos múltiplos para qualificar e quantificar bactérias do grupo dos coliformes totais e termotolerantes, utilizando também a tabela do número mais provável - NMP, e o método de Hoffman para analisar os parasitas presentes. Os resultados para coliformes totais (CT) variaram de 2,7x10 a 9,0x10², já para coliformes termotolerantes (CTT) variaram 1,7x10 a >1,6x10³ para os 3 pontos selecionados. Os exames parasitológicos evidenciaram a presença de Ascaris lumbricoides, Giardia lamblia, Entamoeba coli, Entamoeba histolyca e Balabtidium coli. Considerando-se os resultados obtidos, é possível afirmar que a água do açude São Vicente é considerada imprópria para o consumo humano baseando-se na legislação vigente. Dessa forma, faz-se necessário a implantação de um sistema de saneamento básico eficiente e a conscientização da população que vive próxima ao açude.

The activity of dairy cattle farming has been considered an important generator of income for the economy of the country, having the state of Rio Grande do Sul producing about 4.5 billion liters of milk/year, positioning the state as the third largest milk producer in Brazil. The Free Stall System has been adopted by some family properties in the state, which, although advantageous, requires adequate management of residues in order to avoid contamination of water and soil. The objective of this study was to describe the conduction of FSS carried out in a family property of Rio Grande do Sul, regarding management of solid waste generated by the process, as well as to quantify the demand for water and energy consumption in the activity. The property defined for the study was located in the interior of the municipality of Soledade/RS. The dairy cattle farm was monitored during April and May 2019 for its physical, economic and environmental properties, with emphasis on dairy production. In order to quantify the demand for water and energy in the activity, daily readings were performed during 60 days, with the help of a Unimag-type hydrometer and a Landis + Gyr light meter respectively. With an area of 20 ha designated for cattle farming and a herd of 45 cattle confined in lactation, the current average productivity was 21.6 L/head/day with a consumption of 88.9 L/head/day of water and 57.3 kWh/day of energy. The solid waste generated in the property was classified as domestic residues, pesticide packaging, detergent packaging, bovine waste, and residual water from cleaning purposes. The property has been in an adapting period in order to completely meet the requirements of the environmental legislation.

Os resíduos sólidos constituem um dos grandes problemas enfrentados pela sociedade e uma das formas de minimizar os impactos ambientais, além do cumprimento da legislação correspondente, é sensibilizar a população por meio da Educação Ambiental. Para tanto, é necessário o diagnóstico da percepção ambiental do público alvo, visando estabelecer os parâmetros a serem desenvolvidos. Esse trabalho analisou a percepção dos moradores do bairro Ouro Verde, no município de Nova Olímpia– MT em relação aos resíduos sólidos urbanos (RSU), constituindo um estudo qualiquantitativo, tendo como instrumento de coleta de dados um questionário semiestruturado. Os resultados demonstraram um nível de percepção ambiental insatisfatório devido a carência de conhecimento sobre os RSU, demostrando a necessidade de ações direcionadas para questões educativas pautadas no tripé dasustentabilidade, que envolve reflexos econômicos, ambientais e sociais, bem como a demanda por ações de adequação da gestão de resíduos por parte do poder público municipal.
PANORAMA DA GESTÃO DOS RECURSOS HÍDRICOS NO BRASIL
Authors: Netto Joviniano Pereira da Silva
Published: August 2023

O objetivo central do presente artigo é apresentar, com base em revisão bibliográfica, um panorama da gestão dos recursos hídricos no Brasil a partir da evolução das legislações disponíveis, dos usos da água e de algumas metodologias usadas no diagnóstico de bacias hidrográficas. As condições precárias de saneamento, que são refletidas na má qualidade dos recursos hídricos, apontam desafios que precisam ser superados principalmente no gerenciamento dos recursos ambientais como um todo. Assim, a questão da qualidade dos recursos hídricos e da água consumida pela população é urgente e atual. Os marcos legais brasileiros referentes aos recursos hídricos estão entre os mais coerentes do mundo, inclusive contemplando recomendações internacionais. Porém, o processo de planejamento ainda necessita, na prática, incorporar metas que de fato auxiliem no gerenciamento das bacias hidrográficas, unidades espaciais de análise por excelência, refletindo na qualidade da águadisponível para o consumo.
AGENDA 2030 DA ONU E CONSUMO RESPONSÁVEL: ALCANCE SEGUNDO A REGRA DE COMÉRCIO JUSTO BRASILEIRA
Authors: Caletti Leandro , Stelzer Joana , Etges Evelyn
Published: August 2023

O desenvolvimento sustentável tornou-se tema recorrente tendo em vista a atual tendência de aumento de consumo. A Organização das Nações Unidas (ONU), no contexto da Agenda 2030, apresenta objetivos e metas inerentes ao consumo responsável e à sustentabilidade, temas que encontram ressonância também no âmbito do fenômeno do Comércio Justo. No Brasil, a legislação (ainda vigente) refere-se à Portaria MTE n. 2.060 de 30/12/2014. O objetivo desta pesquisa consiste em avaliar a consecução do Objetivo 12 da Agenda 2030 conforme essa normatização interna. Trata-se de investigação pura, qualitativa, descritiva e indutiva, servindo-se de bibliografia e legislação. Conclui-se que as diretrizes da Portaria MTE nº 2.060/2014 são harmônicas às metas do Objetivo 12 da Agenda 2030 e que a proposta do Comércio Justo é alternativa efetiva para alcançar o propósito de padrões de consumo e produção social, ambientalmente corretos.
PANORAMA DA SUSTENTABILIDADE AMBIENTAL NAS ESTATAIS BRASILEIRAS DEPENDENTES: Um olhar sobre o Plano de Gestão de Logística Sustentável
Authors: Mesquita Aline Santos
Published: August 2023

As políticas ambientais brasileiras avançaram gradualmente com a inclusão do desenvolvimento sustentável como princípio constitucional. Nesse contexto de políticas públicas e responsabilidade ambiental, instituições públicas federais necessitam adequar seu fluxo de gestão para promoção do desenvolvimento nacional sustentável. Esse processo de coordenação de fluxos, considerando a proteção ambiental, a justiça social e o desenvolvimento econômico equilibrado, sinaliza para uma gestão pública futura mais eficiente, conforme a logística sustentável vai ganhando força. O presente estudo, quantitativo, de natureza descritiva, exploratória, tem como objetivo identificar a adesão da ferramenta “Plano de Gestão de Logística Sustentável” (PLS), bem como as práticas de sustentabilidade e racionalização atualmente empregadas pelas estatais brasileiras federais dependentes. A metodologia consistiu em pesquisa documental e pesquisa bibliográfica como fontes para a coleta de informações e composição do referencial teórico, além da veiculação de questionário de pesquisa. Os resultados demonstram que a despeito da ferramenta PLS ainda não ser uma realidade para todas as empresas públicas avaliadas, as práticas sustentáveis e estratégias de redução de consumo de recursos naturais já se encontram implementadas em sua grande maioria. Considerando a importância da administração pública como instrumento de influência para os demais mercados, recomenda-se a inclusão da ferramenta de planejamento de logística sustentável ou outra metodologia similar, no planejamento estratégico das instituições públicas para obtenção de resultados a prazos reduzidos. Novos trabalhos podem pesquisar a efetividade da adoção da ferramenta PLS nos demais órgãos públicos relacionados.

Quintessence of Dust has been on hiatus for more than five years. It's time to resurrect it. Why now? Because it's 2017, and 2017 is not a time to be quiet. The first project involves some remodeling. Quintessence of Dust was built almost ten years ago, with a set of themes and goals that don't all fit in 2017. Most notably, the blog was conceived when I was a Christian, and for five years addressed issues and questions that I knew to be of interest to evangelical Christians. I am happily no...

Easter Everywhere: when is Easter Sunday?
Authors: Royle Stephen
Published: August 2023

A colleague said to me “Everyone is running on fumes with Easter being so late this year.” Really? Is it late? I admit to being completely perplexed by this religious date and its movement around the calendar. I always feel like I am the last to know when it is, let alone whether it is early or late. Let’s have a look at what constitutes an early or a late Easter. The data are available here. This is a quick post with no code example (sorry). I figured the best way...
Puzzles Like You: Lightbulb puzzle
Authors: Royle Stephen
Published: August 2023

I found this great puzzle hidden in an app aimed at children. There are 300 lightbulbs in a row, labelled 1 to 300, each with an on/off switch. We count from 1 to 300 and flick the switches as follows: on “1” all lightbulbs are switched on. On “2” lightbulbs 2, 4, 6, 8 etc. and switched (turning them off). On “3” lightbulbs 3, 6, 9 etc. are switched. If a lightbulb is on when switched it goes off (and vice versa). How many lightbulbs are on by the time we...
