Microwave-enhanced cracking over ZSM-5 (20) catalysts: Taguchi optimization for improved conversion and energy savings
Authors: Sulaiman Muataz M. , Makki Hasan F.
Published: November 2024

For heavy naphtha cracking, the combination of microwave irradiation and ZSM-5 (20) catalyst increases conversion and saves energy. The QVF tube reactor is 240 mm long, 12.7 mm inner diameter with an 80 mm effective zone. The feed goes into the reactor after it has been heated, and the reaction takes place in the catalytic zone, where ceramic particles loaded in the bottom and upper regions of the tube help the feed components and products spread out more evenly. All products were condensed and analysed using gas chromatography. The cracking was done under the following conditions: microwave irradiation (750–1250 W), preheating temperatures (150–250 ˚C), and space velocities (2 and 6 l/hr). The microwave radiation generates hot spots in the catalyst structure, which enhance cracking. The best conversion is (66.77%) at a microwave power of 1250 W, a flow rate of 2 l/hr, and a preheating temperature of 200 ˚C. The nitrogen injection increased conversion in all conditions. Conventional techniques are incapable of cracking heavy naphtha within the temperature range of 150-250 ˚C. Generally, an increase in microwave power and preheating temperature leads to an increase in conversion, while a decrease in flow rate, both with and without nitrogen injection, negatively impacts conversion. This study examined the impact of microwave radiation with a catalyst on residence duration, energy efficiency, and conversion at lowered temperatures.

Published: November 2024

Hidrogênio, o elemento químico mais simples e abundante no universo, é obtido a partir da separação de compostos como hidrocarbonetos ou água. Ele é amplamente considerado o combustível do futuro devido à sua alta densidade energética por unidade de massa, sendo três vezes superior à da gasolina. Suas propriedades vantajosas, especialmente quando comparadas a combustíveis fósseis, têm atraído a atenção da comunidade científica, que investiga seu uso em setores fortemente dependentes de combustíveis fósseis. Esses setores são grandes emissores de CO₂, agravando o efeito estufa. O presente trabalho explora os diferentes processos de obtenção do hidrogênio, com destaque para a eletrólise, que utiliza fontes renováveis para a produção de hidrogênio verde. São analisadas as particularidades de cada método, as matérias-primas utilizadas e a designação por cores que identifica os impactos ambientais de cada processo. Também é apresentada uma análise dos países da América do Sul, com destaque para Chile e Costa Rica, que lideram o desenvolvimento da indústria do hidrogênio verde, avançando na descarbonização de suas matrizes energéticas. Essas nações têm implementado adaptações em setores chave para reduzir o consumo de combustíveis fósseis e promover uma economia mais sustentável.
Enhancing Operational Efficiency in Crushers Through the Use of an Industry 4.0 Based Crusher Control System
Authors: Güler Özge , Çakır Mustafa  Cemal
Published: November 2024

In the aggregate and mining industry, an excessive flow rate of raw material from the feeder, caused by irregularities in the raw material being processed by crushers, can lead to blockages or excessive strain on the crusher. Conversely, a low flow rate of raw material can result in high energy consumption by the crusher, despite operating at a low capacity. The issues encountered in the first group result in excessive energy usage in the secondary and tertiary groups. The study focuses on a system that utilizes artificial intelligence and is based on industry 4.0 principles. The system aims to maintain production in the crusher within a specific range by controlling the flow rates of the feeders using an algorithm. This control is done automatically without the need for user intervention. The system optimizes energy consumption while maximizing production capacity and ensures uninterrupted operation.

The system was developed during the installation phase at an aggregate pilot plant in the Kahramanmaraş Evri region. It assesses the material capacity data using a belt scale on the crusher, feeder, and output conveyor. This data is then compared to the limit values stored in the database, and the system generates an information signal to initiate the required control actions. Based on this matching result, it sends information to the inverter, coordinates the production cycle, manages and documents the process stages using a structured learning system and artificial intelligence logic.The installation procedure was conducted using two distinct density gradation inputs. As a consequence of the reporting, the records in the report were compared during both the active and inactive states of the system. The project achieved an efficiency of 22% in terms of energy consumption per unit capacity. Based on the whole yearly energy usage, a total of 368609.7 kg of carbon emissions were averted. The facility's aggregate crushing capacity was increased by 40%.
DENGUE EM GESTANTES: UMA POTENCIAL AMEAÇA PARA OS DESFECHOS MATERNO- FETAIS?
Authors: Romão Marcela Pereira , Rubira Lara Zaccarelli , Chehter Ethel Zimberg
Published: November 2024

INTRODUÇÃO: a dengue é uma doença febril aguda, causada pelo vírus DENV e transmitida principalmente pelo mosquito do gênero Aedes. Trata-se de uma patologia endêmica majoritariamente em países da Ásia e da América. A evolução clínica costuma dividir-se em três fases: febril, crítica e de recuperação, sendo a febre o sintoma inicial, por vezes acompanhada de anorexia, vômito, diarreia e exantema maculopapular. A fase crítica caracteriza-se pelo aumento da permeabilidade capilar, que resulta em hemorragia, choque e disfunção orgânica pelo acúmulo de líquido, gradualmente reabsorvido na fase de recuperação. O diagnóstico de dengue é fechado a partir da detecção do antígeno NS1; do genoma, por RT-PCR; ou dos anticorpos IgM ou IgG. O tratamento é somente sintomático. Na gestação, estudos sugerem haver aumento de resultados materno-fetais adversos diante da infecção por DENV, além de o diagnóstico desafiador, devido às adaptações fisiológicas gravídicas. Nesse contexto, esta revisão sistemática objetiva analisar como comporta-se a dengue em gestantes e o desfecho da infecção. MÉTODO: foram realizadas buscas no PubMed, com as palavras-chave “dengue pregnancy”, no LILACS, utilizando “dengue gravidez” e “dengue embarazo”, e no Scielo, a partir de “dengue gravidez”. Foram obtidos 188, 18, 21 e 1 resultados, respectivamente, sendo que, após a exclusão por título e resumo, e por texto completo, foram incluídos 32 artigos. RESULTADO: dos desfechos maternos, trombocitopenia grave e morte foram os mais citados nos artigos, seguidos por hemorragia pós-parto, formas mais graves da doença, necessidade de cesárea e pré-eclâmpsia. A repercussão fetal mais prevalente foi a prematuridade, além de natimortos, mortes neonatais, baixo peso ao nascer e oligoâmnio. DISCUSSÃO: os artigos analisados sugerem que a dengue na gravidez eleva o risco de formas graves da doença, hemorragia pós-parto, morte materna, abortamento, natimortos, restrição de crescimento fetal, prematuridade e oligoâmnio, em especial diante de infecções adquiridas no 3º trimestre gestacional. A transmissão vertical também aumenta no final da gestação. CONCLUSÃO: esta revisão destaca que a dengue é especialmente relevante durante a gestação, com significativo impacto negativo nos desfechos maternos e fetais. Entretanto, ainda são necessários mais estudos para maior aprofundamento, já que não há consenso.

Published: November 2024

The article "Electoral Political Rights and the Importance of Voting in the Light of the Legal System" analyzes the evolution of electoral political rights in Brazil and in the world, highlighting the relevance of voting in the legitimation of democratic institutions and popular sovereignty. With a historical-constitutional approach, the study reviews the trajectory of political rights, from Antiquity to the present day, focusing on the expansion of political participation, including women, illiterates and young people. In Brazil, the 1988 Constitution consolidated universal and direct suffrage, strengthening representative democracy. However, the article identifies contemporary challenges, such as crises of representation, political disinterest, and corruption, which affect the quality of democracy. The use of technologies, such as electronic voting machines, is highlighted as an important innovation to ensure transparency and security in elections. The text concludes that, despite the advances, it is crucial to promote political education and electoral awareness to ensure the critical and informed exercise of political rights. Proposals for reform in the legal system, with an emphasis on civic education and digital citizenship, are presented as solutions to address these challenges and strengthen democracy. The active and conscious participation of citizens, especially young people, is seen as essential for the consolidation of a robust and inclusive democratic system.

Published: November 2024

The purpose of this study is to develop a problem posing activity using visual representations, to apply it to the proportion and proportional distribution unit for 6th graders, and to analyze the level and error patterns of the problems made by students, and changes in the level of proportional reasoning. The level of problem was analyzed in terms of completion, communication, and everydayness, and errors that appeared by problem level were examined. The level of proportional reasoning was classified into levels 0 to 3 according to the strategy used in the test paper, and the pre and post test results were compared and analyzed. In the activity, the most problems created by 6th graders were level 3, and more errors appeared in completion and everydayness than communication. As a result of the proportional reasoning test, more significant changes were observed in the quantitative task than in the qualitative task, and the percentage of correct answers was higher when visual representation was used. It suggests that this activity can be an useful learning method in proportional reasoning, and that it is necessary to help understanding of proportionality by providing tasks reflecting everydayness

Authors:   The Korea Society Of Educational Studies In Mathematics, Yoon Jungeun , Kwon Oh Nam
Published: November 2024

With the advent of the era of digital transformation, digital·AI-related policies are being actively promoted in the curriculum.
This study aims to explore high school mathematics teachers’ practice of digital·AI curriculum based on ecological approach to teacher agency. For this, interviews were conducted with four high school mathematics teachers, focused on the following research questions: 1) How do high school mathematics teachers practice the digital·AI curriculum? 2) What are the factors that influence high school mathematics teachers’ practice of the digital·AI curriculum? The results of the study showed that high school mathematics teachers practiced the digital·AI curriculum, showing various teacher agency, ranging from neutral·critical acceptance, passive practice, and proactive implementation. In addition, these various practices are influenced by personal factors (prior experience or knowledge, beliefs to mathematics classes, recognition to future competencies) and contextual factors (school environment, attitudes of mathematics teachers at the same school, teacher learning community). This study discusses the usefulness and value of ecological approach to teacher agency in interpreting mathematics teachers’ curriculum practice, and suggests the need for structural, environmental, cultural support to enable teachers' autonomous and independent practice of the digital·AI curriculum.

Authors:   The Korea Society Of Educational Studies In Mathematics, Noh Jeong-Won , Kim Min-Ji , Kim Min-Ju , Youn Sang-Gyun
Published: November 2024

The purpose of this paper is to examine pre-service teachers' mathematical content knowledge and perceptions regarding the justification of the differentiation of the exponential function in relation to the connection between school mathematics and university mathematics. We analyzed and categorized how pre-service teachers justified the differentiation of the exponential function through semi-structured interviews, examined whether the gaps in the learning trajectory in school mathematics were rigorously addressed, and surveyed their perceptions about these gaps. This study revealed that the justification methods of pre-service teachers could be categorized into seven types, and they had difficulty rigorously addressing the gaps. Many pre-service teachers were unaware of the gaps in the learning trajectory and agreed on the need for consistent learning trajectories between school and university mathematics. This study highlights the need to improve pre-service teacher education by examining the mathematical content knowledge required for mathematics teachers in connection to school mathematics.

Authors:   The Korea Society Of Educational Studies In Mathematics, Hwang Jinam
Published: November 2024

The purpose of this study was to examine elementary preservice teachers’ subject matter knowledge (SMK) of prisms, pyramids, cylinders, and cones. The analysis of the preservice teachers’ SMK regarding the extension of each solid figure revealed that they had more difficulties with cylinders and cones compared to prisms and pyramids. Some of them classified cylinders and cones as solids of revolution based on the instructional sequence of the curriculum. This study also analyzed their SMK by dividing it into three categories: (a) mathematical definitions, (b) school mathematics, and (c) instructional sequence. The mathematical definitions group demonstrated a high overall level of specialized content knowledge (SCK). The school mathematics group, on the other hand, had mostly common content knowledge (CCK). The instructional sequence group often showed SCK only for cylinders and pyramids. Based on these analysis results, we proposed specific measures for preservice teacher education to develop their SMK and knowledge at the mathematical horizon (KMH).

A manuscript copy of a collection for the Welsh triple harp by John Parry (Ruabon)
Authors: Lonnert Lia , Davies Mikkelborg Helen
Published: November 2024

A manuscript copied by the Swedish19th-century harpist Adolf Sjödén claims to be a copy of the original work by the Welsh 18th-century composer John Parry (Parry Ddal/Blind Parry, Ruabon) (1710-1782). The manuscript appears to be in the style of John Parry, with resemblances to his other published works for the Welsh triple harp although many of the tunes in the manuscript are unique. Adolf Sjödén's role as the copyist adds an additional layer of historical significance, and the manuscript provides a glimpse into the musical traditions of 18th-century Wales. The discovery contributes to the ongoing efforts to preserve and understand the rich cultural heritage of Welsh music.
Individual dynamics mathematical patterns of qualified basketball players competitive performance
Authors: Lushnikov Oleg , Pushkova Yanina , Belyaev Kostiantyn
Published: November 2024

Background and purpose
Since the goal in sport is to overcome one's limitations and take one's functional state to a qualitatively new level, forecasting is an integral part of managing any process, including the athlete's training process.
Purpose: to develop an algorithm and identify patterns of individual dynamics in competitive performance of eligible basketball players.
Materials and methods
The main team players of the men's basketball team of H.S. Skovoroda Kharkiv National Pedagogical University. Twelve matches of the experimental team playing against national teams of other universities were analyzed. Observations were made on the players during the championships played by student teams from Kharkiv. For each player, the number of shots and hits from short, mid and long range, goal assists, shots and hits from the penalty line, and turnovers were recorded. To identify individual patterns of competitive performance dynamics, indicators such as 'total positive points in a match', which most accurately reflect a player's 'positive' contribution to the outcome of a match, were used. To identify individual regularities in competitive performance dynamics, indicators such as 'total positive points in the match', which most accurately reflect the 'positive' contribution of players to the outcome of the match, were used.
Results
It was determined that the process of change in competitive performance should be treated as a variable process. The most appropriate function to describe this model is the sine function. It was shown that the regression model of the individual dynamics of competitive activity of the players of the Ukrainian national basketball team has a sine dependence, which is defined by the regression equation S + = a + bsin ((2π / t) (Т-c)). Where the coefficient a is the average value of a player's match performance, b is the amplitude of the change in a player's match performance, t is the previous period of a player's match performance and c is the value period in the first analyzed match.
Conclusion
The application of the regression sinusoidal model proved to be effective in practical studies. This is because, using only data from technical reports, it is possible to very quickly predict periods of 'rise' and 'fall' in an individual's game performance, which is useful for adjusting training programs and identifying psychophysiological individual characteristics of players.
Miskonsepsi terhadap Komersialisasi dan Komodifikasi Akad dalam Fikih Muamalah Kontemporer (Analisis Maqasidus Syariah)
Authors: Khulwah Juhrotul
Published: November 2024

Penerapan akad-akad dalam fikih muamalah kontemporer sering kali mengalami miskonsepsi, terutama terkait komersialisasi dan komodifikasi yang dilakukan oleh masyarakat maupun lembaga. Ketertarikan terhadap praktik muamalah ini didorong oleh nilai etika dan transparansi yang terdapat dalam ekonomi Islam, seperti yang diterapkan oleh lembaga keuangan syariah. Namun, praktik akad yang tidak sesuai dengan hukum syariah dapat mengurangi daya tarik dan integritas sistem tersebut. Tujuan dari penelitian ini adalah untuk meluruskan Kembali tentang pengaplikasian akad-akad yang sesuai dengan hukum ekonomi syariah (muamalah). Metode yang digunakan adalah Pustaka atau library research, metode library research merupakan salah satu  metode dari penelitian jenis kualitatif. Data data dan bahan yang digunakan untuk mengkaji dalam penelitian inibersumber dari buku, jurnal, kitab dan lain sebagainya. Berdasarkan penelitian terungkap bahwa banyak sekali terjadi miskonsepsi terhadap komersialisasi dan komodifikasi akad dalam praktik muamalah di dalam Masyarakat, banyak sekali akad yang seharusnya tidak dibolehkan mengambil keuntungan tetapi dalam praktiknya diambil keuntungan, maka harus diluruskan lagi bahwa dalam fikih muamalah ada dua jenis akad yang sudah paten yaitu akad tabaruk dan akad tijarah, tidak boleh dicampur adukkan antara keduanya, karena akan menghilangkan ciri khas dari ekonomi Islam yang dikenal oleh Masyarakat, yaitu system ekonomi yang memegang erat prinsip dan etika. Penelitian ini menyimpulkan bahwa diperlukan edukasi lebih lanjut mengenai perbedaan akad untuk mencegah komersialisasi yang tidak sesuai, serta pentingnya peran aktif lembaga keuangan syariah dan pemerintah dalam menjaga integritas praktik keuangan syariah agar sesuai dengan prinsip Maqasid Syariah.

A new contribution to the Newton-Leibnitz differentiation of polynomial approximations in thermal processes
Authors:   University of Belgrade, High Technical School, MILIĆEVIĆ Miroslav S. , NEJKOVIĆ Valentina M. ,   University of Niš, Faculty of Electronic Engineering
Published: November 2024

This paper presents the determining of the critical cooling time and preheating temperature for welding. The primary equation which represents the cooling temperature is transcendent and, as such, it is not suitable for explicit solving. Hence, the author has investigated the appropriate interpolation polynomial which should align the polynomial level with the possibility of providing good accuracy of the approximation. Since the application and design of the welding included calculation of the derivatives of the polynomial, it is concluded that the accuracy of the derivative is not precise, nor does it follow the accuracy of the polynomial approximation. This research showed that the current theory for differentiation of the polynomial approximation does not provide precise results, although all the requirements of differentiability are provided. There are certain shortcomings in these actions, which imply that the currently known method of differentiation cannot be used. The new method of differentiating includes relatively small differentiating error regarding the exact value of the derivative, and the error for the polynomial approximation relating to the exact formula is not surpassed. The attempt to solve the design problem in thermal processes also makes a contribution in differentiation.

In this paper, we investigate the tracking control problem for a class of brush direct current (DC) motor systems driving a one-link robot manipulator subject to asymmetric full-state constraints. By constructing a state-dependent nonlinear transformation function (NTF), we present an adaptive robust dynamic surface control (DSC) strategy that can directly address both symmetric and asymmetric state constraints, so that there is no need to convert the problem of state constraint into the constraints on tracking errors as necessitated by the Barrier Lyapunov Function (BLF)-based existing works. Furthermore, by employing the first-order filter and constructing a new coordinate transformation, the demanding feasibility condition imposed on the BLF methods is removed, allowing the designer more freedom to select design parameters. Moreover, it is worth mentioning that under the proposed nonlinear transformation function the extra condition on the constraining function is not required. The effectiveness of the proposed control is verified via the Simulation results.

This paper proposes an approach to analyze the performance of radio frequency/underwater wireless optical communication (RF/UWOC) systems using Mellin inverse transform. This analysis combines heterodyne detection (HD) and direct detection /intensity modulation (IM/DD). The RF link from land ground stations to relay stations follows the Nakagami-m distributed channel. The UWOC link from the relay station to the underwater vehicle is modeled using the double generalized gamma (GG) distribution with pointing errors. By employing the Fixed Gain Amplification and Forwarding (AF) protocol, the probability density function (PDF) of the RF/UWOC link is derived using the Mellin inverse transform, expressed in the form of the Meijer-G function. In addition, expressions for the outage probability and bit error rate of the mixed system were derived. Monte Carlo simulations validated the analysis results, which demonstrated the superior performance of HD technology.
