THERMOGRAVIMETRIC ANALYSIS OF PULVERIZED RICE HUSK WASTE CATALYTIC COMBUSTION WITH NATURAL ZEOLIT
Authors: Hamidi Nurkholis , Yuliati Lilis , Purnami Purnami , Faiz Naufal  Muhammad
Published: July 2024

Rice husk is a type of agricultural waste that generated from rice production activities. The number continues to increase in line with the increasing food needs of the people in Indonesia. This study aims to determine the effect of the addition of natural zeolite as a catalyst and to determine the effect of natural zeolite mass percentage variation in the mixture on rice husk waste catalytic combustion by using the thermo gravimetric analysis method. The results of this study show that there is an effect of adding natural zeolite catalysts with the mass percentage of natural zeolite variations on the combustion characteristics and activation energy of each mixture. Increasing the mass percentage of natural zeolite catalysts can affect the reaction process become faster and minimize the effort required, but it was found that if the amount of natural zeolite catalyst is too much, it only adds to the heating load which causes slower reaction. The mixture of rice husks with 10% natural zeolite catalyst is the most optimal mixture because it has the lowest required activation energy value and the combustion reaction phases are achieved at a lower temperature than 5% and 15% mass percentage variations.

Authors: Salsabila Lubna , Ariany Ria , Koeswara Hendri
Published: July 2024

Effective city solid waste management has become a critical issue for communities globally due to the rapid pace of urbanization and increasing environmental concerns. The convergence of economic development and environmental preservation in Batam City, Indonesia, has underscored the necessity for inventive waste management approaches. This study examines the impact of dynamic governance and community empowerment in addressing the intricate waste issue in Batam City. The research uses a qualitative approach to investigate the underlying reasons for waste management difficulties. It investigates how adaptive governance might improve stakeholder cooperation and decision-making based on facts. Effective policy implementation relies on public interaction, yet meaningful participation remains difficult. Prior research suggests that individuals are more inclined to engage in matters that directly impact them, and ambiguous implementation protocols and a lack of confidence in political establishments frequently hinder community engagement in environmental policy. The waste management techniques in Batam City are conventional and inefficient due to limited government resources, highlighting the necessity for a more comprehensive strategy. The study's results indicate that implementing dynamic governance, which involves the flexibility to adapt and collaborate with stakeholders, can enhance waste management procedures. In addition, applying social capital theory can facilitate community empowerment, leading to a heightened sense of ownership and active engagement in waste management initiatives. Communities can enhance the effectiveness and durability of waste management systems by utilizing social networks, trust, and shared standards. This study emphasizes the significance of integrating inventive governance approaches with community-led efforts to tackle urban trash issues and advance sustainable development in Batam City.
Wat de dichter witte moat. Filosofyske fasetten fan Obe Postma syn dichterskip
Authors: Veenbaas Jabik
Published: July 2024

In this article several philosophical aspects of the poetry of the Frisian poet Obe Postma 1927 are considered. Earlier critics held out that Postma’s treatment of the sublime was essentially kantian. However, a closer look proves that Postma was a romantic rather than a kantian. Postma’s treatment of the sublime is not characterized by rationality and by transcendental distance, but by feeling and transcendent proximity. Postma’s recurring theme of poetry as the mediating and connecting force of the world may also have been inspired by the romantics. And around 1922 he probably found the validity of this theme confirmed and reinforced when he read Lebensanschauung by the vitalistic philosopher Georg Simmel. In one of his notebooks he made an extract of this book in which he records the idea that people have the power to transcend their lives in their awareness of the possibilities and boundaries of their own knowledge. In the brilliant poem ‘Wat de dichter witte moat’ (‘What the poet must know’) we see the outcome of his philosophical-poetical quest, when we notice how he compares his own knowledge of the world to that of the great German poet Rilke and full of confidence states that he may have grown up ‘in the surveyable/ Community of the village’, but has known miracles that Rilke never knew. This poet knows enough.
Medios digitales y percepción de la violencia
Authors: Erazo-Patiño Lorena Andrea , Laverde-Rodríguez Carlos Alfonso , Devia-Acevedo Emerson David
Published: July 2024

Este artículo investiga la organización criminal conocida como el Tren de Aragua y su rápida expansión en Colombia, Perú, Ecuador y Chile en los años recientes. Con base en ciencia de datos y la herramienta Meltwater, se analiza la escucha social en medios digitales sobre este fenómeno entre 2021 y 2023. Los hallazgos muestran un aumento en la cobertura mediática al respecto, que enfatiza en la debilidad estatal para prevenir y sancionar el crimen. Este grupo capitaliza vacíos institucionales y la movilidad de migrantes venezolanos para establecer economías criminales ajustadas a las particularidades de cada país donde se establece. A su vez, los medios han amplificado el uso de la violencia por parte de esta organización y aumentado la preocupación pública por la ineficacia gubernamental. Estos hallazgos subrayan la necesidad de respuestas coordinadas para hacer frente a organizaciones criminales transnacionales en América Latina.

Published: July 2024

Este artículo analiza la capacidad de los programas de policía de proximidad o policía comunitaria para fomentar la confianza en la policía en dos localidades: el municipio de Nezahualcóyotl en el estado de México y el Centro Histórico de la Ciudad de México. Para ello se analizan los resultados de una encuesta aplicada a los habitantes de las dos localidades, mediante el desarrollo de un modelo de regresión logística binomial. Los resultados muestran que en ambos casos estas estrategias de proximidad han conseguido un impacto positivo en la confianza de los habitantes, más allá de otros factores individuales y contextuales. No obstante, la eficacia de la policía para prevenir delitos se muestra como el determinante principal de la confianza en ambos casos.
The Role of Assistive Technology in Enabling Older Adults to Achieve Independent Living: Past and Future
Authors: Sweeting Anna , Warncken Katie A , Patel Martyn
Published: July 2024

In this viewpoint, we present evidence of a marked increase in the use of assistive technology (AT) by older adults over the last 25 years. We also explain the way in which this use has expanded not only as an increase in terms of the total number of users but also by going beyond the typical scopes of use from its inception in 1999 to reach new categories of users. We outline our opinions on some of the key driving forces behind this expansion, such as population demographic changes, technological advances, and the promotion of AT as a means to enable older adults to achieve independent living. As well as our review of the evolution of AT over the past 25 years, we also discuss the future of AT research as a field and the need for harmonization of terminology in AT research. Finally, we outline how our experience in North Norfolk (notably the United Kingdom’s most old age–dependent district) suggests that cocreation may be the key to not only successful research trials in the field of AT but also to the successful sustained adoption of AT beyond its original scope of use.

Published: July 2024

UNSTRUCTURED

Despite excitement around artificial intelligence (AI)–based tools in health care, there is work to be done before they can be equitably deployed. The absence of diverse patient voices in discussions on AI is a pressing matter, and current studies have been limited in diversity. Our study inquired about the perspectives of racial and ethnic minority patients on the use of their health data in AI, by conducting a cross-sectional survey among 230 participants who were at least 18 years of age and identified as Black, Latinx, Indigenous, or Asian. While familiarity with AI was high, a smaller proportion of participants understood how AI can be used in health care (152/199, 76.4%), and an even smaller proportion understood how AI can be applied to dermatology (133/199, 66.8%). Overall, 69.8% (139/199) of participants agreed that they trusted the health care system to treat their medical information with respect; however, this varied significantly by income (P=.045). Only 64.3% (128/199) of participants felt comfortable with their medical data being used to build AI tools, and 83.4% (166/199) believed they should be compensated if their data are used to develop AI. To our knowledge, this is the first study focused on understanding opinions about health data use for AI among racial and ethnic minority individuals, as similar studies have had limited diversity. It is important to capture the opinions of diverse groups because the inclusion of their data is essential for building equitable AI tools; however, historical harms have made inclusion challenging.
Objective habit metrics correlate to objective medication adherence: a retrospective study on 15,818 subjects from clinical studies (Preprint)
Authors: Pironet Antoine , Phillips L Alison , Vrijens Bernard
Published: July 2024

BACKGROUND

Medication adherence, or how patients take their medication as prescribed, is a global public health issue. Improving medication-taking habit might be an effective way to improve medication adherence. However, habit is difficult to quantify, and conventional habit metrics are self-reported, with recognized limitations. Recently, several objective habit metrics have been proposed, based on objective medication-taking data.

OBJECTIVE

Explore the correlation between objective habit metrics and objective medication adherence on a large dataset.

METHODS

The MEMS® Adherence Knowledge Center, a database of anonymized electronic medication adherence data from ambulant subjects enrolled in past clinical studies, was used as the data source. Electronic medication adherence data from subjects following a once-daily regimen and monitored for 14 days or more were extracted. Two objective habit metrics were computed from each subject’s medication intake history: standard deviation of the hour of intake and weekly cross-correlation. Objective medication adherence was computed usin15,818 subjects met the criteria. The two objective habit metrics were associated with the two objective adherence metrics (all p < 0.001). A lower daily or weekly variability in the timing of medication intakes is associated with a better medication adherence. However, no variability is not the norm. Among the numerous factors influencing medication adherence, habit strength is an important one.g the proportion of doses taken and the proportion of correct days.

RESULTS

15,818 subjects met the criteria. The two objective habit metrics were associated with the two objective adherence metrics (all p < 0.001). A lower daily or weekly variability in the timing of medication intakes is associated with a better medication adherence. However, no variability is not the norm. Among the numerous factors influencing medication adherence, habit strength is an important one.

CONCLUSIONS

Objective habit metrics are correlated to objective medication adherence. Such objective habit metrics can be used to monitor patients and identify those who may benefit from habit-building support.

Authors: Yang Fangjing
Published: July 2024

The concept of sustainable development drives companies to pursue improving the efficiency and quality of ESG management. As a management tool for corporate strategy implementation, the balanced scorecard (BSC) was developed to achieve corporate profit maximization strategy, and with the globalization of sustainable development, more and more companies are trying to achieve value creation in environmental, social and governance. However, the inherent limitation of the traditional balanced scorecard - the lack of environmental and social responsibility perspectives - does not satisfy the strategic goal of companies to enhance their ESG management capabilities and ultimately achieve sustainable development. Therefore, this paper incorporates the concept of sustainable development on top of the traditional balanced scorecard to help enterprises carry out ESG management and further realize their long-term development goals.

Authors: Silva Michael de Alencar , Silva Tarcísio Pedro da
Published: July 2024

The present study aimed to investigate the relationship between investor sentiment and the return on the first day of an IPO, moderated by emerging market risk factors, from 2013 to 2021. The sample included 105 companies that carried out an IPO in this period. The econometric method used was the regression analysis. As main results, it was observed that investor sentiment, measured by market variables and trading volume, positively affected returns on the first day of the IPO, even when moderated by idiosyncratic country risk factors. Thus, the research hypotheses were accepted. In addition to the debate on the influence of investor sentiment on the performance of IPOs, the theoretical contribution of the research involves the empirical expansion of the effects of country risk factors. Therefore, it was concluded that investors seek returns on the first day of the IPO, considering their sentiment towards the market and reacting positively to the risk factors of emerging markets.
Enhanced Integration of Kinematic free surface boundary condition to third order Accuracy for Wave Transformation Modeling
Authors: Hutahaean Syawaluddin
Published: July 2024

The relationship between wave amplitude and other wave constants is derived through the integration of the Kinematic Free Surface Boundary Condition (KFSBC) over time, yielding the wave amplitude function. This function presents the characteristics of wave breaking to determine the breaker length index—the ratio of breaking wave height to breaking wave length. Previous research achieved integration at a zero-order accuracy level, assuming small wave amplitude and long wave, resulting in a notably large critical breaker length index and wave steepness. In this research, KFSBC integration was advanced to second and third-order accuracies, yielding a wave amplitude function that significantly reduces the critical breaker length index and wave steepness compared to zero-order integration. Subsequently, utilizing the third-order wave amplitude function, a comprehensive wave transformation model incorporating shoaling, breaking, refraction, and diffraction was developed, demonstrating robust model performance.

Published: July 2024

Abstract: Music Mood Recognition aims to allow computers to understand the emotions behind music the way humans do, in order to facilitate better perception of media by computers to aid in enhanced services like music recommendations, therapeutic interventions, and Human Computer Interaction. In this paper, we propose a novel approach to improving Music Mood Recognition using a multi-modal model that uses lyrical and audio features of a song. Lyrical features are analysed using stateof-the-art open-source Large Language Models like Microsoft Phi-3 to classify lyrics from one of the four possible emotion categories as per the James Russel Circumplex Model. Audio features are used to train a Deep Learning (ConvNet) model to predict emotion classes. A multimodal combiner model with Audio and Lyrics is then trained and deployed to enable accurate predictions. The dataset used in this research is “MoodyLyrics”, a collection of 2000+ songs classified with one of 4 possible emotion classes as per the James Russel Circumplex Model. Due to compute limitations, we are using a balanced set of 1000 songs to train and test our models. The workin this paper outperforms most other multimodal researches by allowing higher accuracies with universal language support

How can PBL promote critical thinking skills in biology material? A systematic literature review in reputable journals
Authors: Usman Ali , Munandar Kukuh , Utomo Agus Prasetyo
Published: July 2024

: The Merdeka Curriculum requires teachers to apply various learning models, including PBL, to achieve learning objectives, including critical thinking skills. However, in the context of biology learning, the application of the PBL model is rarely considered to improve students' critical thinking skills, and research on this is still limited. Therefore, this research is essential because there is no complete analysis of the impact of the PBL learning model on critical thinking skills in biology indexed by Scopus. This study uses the SLR method to investigate the effect of the PBL learning model on students' critical thinking skills in biology material. This research method follows the PRISMA model for selecting articles based on specific criteria in the SCOPUS database. The research results show that presentation and discussion methods dominate biology learning, while there is a lack of attention to students' critical thinking and a lack of electronic teaching materials. On the other hand, problem-based learning helps students understand and apply biological material and develop critical thinking skills by emphasizing the application of knowledge, analysis, synthesis, and evaluation and involving students in group discussions to motivate critical thinking. Research shows that PBL effectively improves students' critical thinking, supported by various learning models and media that strengthen students' critical thinking skills. In conclusion, applying the PBL model allows students to focus on specific topics, understand scientific concepts, and overcome challenges through data analysis, hypothesis generation, and deductive reasoning. This model encourages critical thinking and active participation of students. Teachers are expected to be able to use various learning models to improve students' thinking abilities.

Published: July 2024

Using near-term quantum computers to achieve a quantum advantage requires efficient strategies to improve the performance of the noisy quantum devices presently available. We develop and experimentally validate two efficient error mitigation protocols named ``Noiseless Output Extrapolation" and ``Pauli Error Cancellation" that can drastically enhance the performance of quantum circuits composed of noisy cycles of gates. By combining popular mitigation strategies such as probabilistic error cancellation and noise amplification with efficient noise reconstruction methods, our protocols can mitigate a wide range of noise processes that do not satisfy the assumptions underlying existing mitigation protocols, including non-local and gate-dependent processes. We test our protocols on a four-qubit superconducting processor at the Advanced Quantum Testbed. We observe significant improvements in the performance of both structured and random circuits, with up to 86% improvement in variation distance over the unmitigated outputs. Our experiments demonstrate the effectiveness of our protocols, as well as their practicality for current hardware platforms.
Thermal masses and trapped-ion quantum spin models: a self-consistent approach to Yukawa-type interactions in the λϕ4 model
Authors: Martínez Pablo Viñas , López Esperanza , Bermudez Alejandro
Published: July 2024

The quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins, which are encoded in the internal electronic states of the ions, and measured in experiments that probe the real-time dynamics. These interactions can be accounted for by a long-wavelength relativistic theory, where the phonons are described by a coarse-grained Klein-Gordon field ϕ(x) locally coupled to the spins that acts as a carrier, leading to an analogue of pion-mediated Yukawa interactions. In the vicinity of a structural transition of the ion crystal, one must go beyond the Klein-Gordon fields, and include additional λϕ4 terms responsible for phonon-phonon scattering. This leads to quantum effects that can be expressed by Feynman loop integrals that modify the range of the Yukawa-type spin interactions; an effect that could be used to probe the underlying fixed point of this quantum field theory (QFT). Unfortunately, the rigidity of the trapped-ion crystal makes it challenging to observe genuine quantum effects, such as the flow of the critical point with the quartic coupling λ. We hereby show that thermal effects, which can be controlled by laser cooling, can unveil this flow through the appearance of thermal masses in interacting QFTs. We perform self-consistent calculations that resum certain Feynman diagrams and, additionally, go beyond mean-field theory to predict how measurements on the trapped-ion spin system can probe key properties of the λϕ4 QFT.

The paper presents the relevance of environmental problems in modern society. In particular, the urgent environmental crises of the Khabarovsk Territory are analyzed. The study considers the pollution of the shores of all water bodies of the region and adjacent water areas with household garbage. The paper provides information on the measures taken by the Ministry of Natural Resources of the Khabarovsk Territory to form ecological awareness of the population. An overview of the quantitative indicators of the campaign «Water of Russia» for three years in the Khabarovsk Territory is provided. The paper also includes other environmental actions carried out within the framework of the regional Eco-marathon. We are also talking about the fact that environmental safety is one of the five subsystems included in the national security system of the Russian Federation. The need to turn public consciousness towards environmental friendliness is justified, the level of consciousness being characterized by high responsibility for actions concerning the environment. Different approaches to the concept of «ecological consciousness» are considered, clarifying the meaning of the term. The indicator of the formation of ecological consciousness is the participation of citizens in eco-volunteer activities. The authors believe that constant work can help to form environmentally responsible public consciousness. The study is feasible in an educational, scientific, campaigning and business environment. It is important to provide information support and promotion of eco-volunteer actions, as well as stimulating and encouraging events. The apper uses methods of analysis, synthesis, systematization, generalization. In conclusion, voluntary environmental public associations create the basis for the formation of sustainable environmental awareness, not only among young people, but also in the professional sphere.

As a result, we can unequivocally say that the role of the BRICS member countries in Africa is significant and every year it will only increase, as the strength of the association itself, its geography and the number of participants grows. Each of the bloc countries plays its own significant role in the life of the continent.
The Stateof Exports of High-Tech Products in Russia

Aim. To determine the general state of Russia’s high-tech exports in the following areas: the relationship with other sectors of the economy and with the dynamics of GDP, positions on the world stage, relations with partner countries.Tasks. To achieve the aim of the study, the following tasks were set: to consider the dynamics of Russia’s export structure, to explore Russia’s position in the world in high-tech exports, to calculate the time lag of Russia’s lag behind the leading countries in high-tech exports, to analyze Russia’s role in the hightech market of the main partner countries, to explore the structure of Russia’shigh-tech exports in the context of commodity groups.Methods. To determine high-tech exports and imports, the methodology of the World Bank is used, according to which 9 industries (aerospace, computer and office equipment, electronics and telecommunications, pharmaceuticals, scientific instruments, electric machines, chemicals, nonelectric machines and weapons), including 79 commodity nomenclatures. At the same time, based on the availability of information, the values for the export of weapons are not taken into account.Results. The analysis of changes in high-tech exports has been carried out, which identifies periods of negative changes that coincide with periods characterized by adverse circumstances in the country and the world (pandemic, geopolitical and geo-economic tensions). When comparing graphs of high-tech exports and GDP, ambiguous results were obtained, taking into account the consideration of high-tech exports in calculating GDP. The time lags of the backlog have been calculated, according to which, in most cases, the values of the leading countries in high-tech exports are achievable, but the time lags themselves are enormous. The commodity spectrum of high-tech exports and imports of the Russia is considered, according to which Russia exports the entire commodity spectrum of the high-tech industry.

Conclusions. The dominant role in Russia’s exports is still assigned to fuel and mining products with observed changes in terms of increasing the share of industrial products, including high-tech products, in which Russia, although an active participant, is nevertheless at a disadvantage in interactions with the main partner countries.

Economic Crisis Treatment Based on Artificial Intelligence
Authors: F. Abd El-Aal Mohamed
Published: July 2024

Abstract: There are many possible causes of an economic crisis—a financial downturn, a banking meltdown, political strife (e.g., the Russia-Ukraine war), or a health-related catastrophe (e.g., Covid-19). Some of these crises are expected, while others are “bolts from the sky.” However, what is certain is that all these crises, whatever their cause, have a negative impact on global gross domestic product (GDP). If we can identify the components of output that have the most impact in an economic crisis, we might be able to mitigate its effects. Therefore, this paper uses machine learning algorithms to determine how the components of expenditure and sectoral value-added approach impact global GDP. The gradient boosting algorithm is the most accurate model for predicting and determining the impact of independent variables on a dependent variable. The results indicate that government spending has the largest effect on global GDP, accounting for 68.3% of the impact. The economic sector with the most impact on global GDP is the service sector, which affects global output by 42.3%, followed by the agricultural sector at 30.2%. Thus, stimulating government spending and the service sector may reduce the negative effects of an economic crisis.
A note on repunit number sequence
Authors: Santos Douglas Catulio , Costa Eudes Antonio
Published: July 2024

In this paper, we investigate the classical identities of the repunit sequence with integer indices in light of the properties of Horadan-type sequences. We highlight particularly the Tagiuri-Vajda Identity and Gelin-Cesàro Identity. Additionally, we prove that no repunit is a perfect power, either even or odd. Finally, we address a divisibility criterion for the terms of repunit  rn by a prime p and its powers.
Indeterminações nos materiais didáticos do CEFET-MG: um estudo histórico de 1970 aos tempos atuais
Authors: Fonseca Nina Leão , Lara Otávio Gabriel Alves , Pagani Érica Marlúcia Leite , Oliveira Davidson Paulo Azevedo
Published: July 2024

O objetivo do presente trabalho é analisar, com base nos Três Mundos da Matemática como as indeterminações são apresentadas em quatro materiais didáticos de matemática produzidos e utilizados por professores do CEFET MG nos últimos cinquenta anos. A teoria foi desenvolvida por David Tall, apoiada na ideia de que o pensamento matemático está ancorado em três mundos: o Conceitual Corporificado, o Operacional Simbólico e o Formal Axiomático. De acordo com nossas análises, a abordagem do conceito de Indeterminação nos materiais analisados mudou consideravelmente, com uma ênfase nos mais antigos no mundo Operacional Simbólico, e nos documentos mais recentes, uma ênfase no mundo Conceitual Corporificado e Operacional Simbólico.
Prática pedagógica no ensino de matemática: momentos de matematizar
Authors: Santana Eurivalda Ribeiro dos Santos , Couto Maria Elizabete Souza
Published: July 2024

Este artigo tem como objetivo apresentar e descrever as possibilidades de realização de uma metodologia investigativa no ensino de Matemática na perspectiva do matematizar. Um trabalho que está sendo realizado em escolas da rede pública de ensino, com professores que lecionam matemática. Para esse estudo a prática aqui descrita segue com um exemplo desenvolvido por professores que lecionam no 5º ano do Ensino Fundamental, durante um período de um mês, com cinco Momentos do Matematizar com: tema; problematização; dados, informações e registros; definições; e para conclusão. A prática descrita segue a seleção do tema - Universo: uma viagem pelo espaço -, dos conceitos a serem estudados - fração, sistema solar, leitura -, a contextualização e o planejamento das atividades realizadas com os estudantes foram construídos em conjunto com professores e o grupo de pesquisa, considerando o tema e os conceitos. O movimento de questionar, contextualizar, desenvolver a criatividade e curiosidade dos estudantes fizeram-se presentes em todos os Momentos do Matematizar. Tal condição indica que os Momentos de Matematizar não se constituem em um ciclo fechado, mas se movimentam possibilitando novas práticas, com contextualização e problematização para continuar estudando o mesmo objeto do conhecimento ou outros. Por isso, os Momentos do Matematizar se constituem em uma metodologia investigativa que possibilita processos para a aprendizagem dos estudantes.
