Published: October 2023

In this paper we describe the results of the influence of temperature in the range of 280–340 K on the luminescence of bimetallic Eu/Tb complexes with N-heterocyclic ligand L based on 2,2′-bipyridyldicarboxylic acid in acetonitrile. The experiments were carried out for systems with various Eu/Tb ratios. The stability of the complexes of the ligand L with metal M (Eu or Tb) was determined using spectrophotometric titration in acetonitrile solutions. The LM complexes’ stability constants were found to be typical for these systems; however, the stability of Eu complex is slightly higher than that for Tb. Along with rising temperature, we observed a decrease in Tb emission intensity and, at the same time, an enhancement in Eu luminescence. An explanation of Eu luminescence enhancement involves the appearance of charge transfer states, bands of which can be observed in the Eu luminescence excitation spectra as difference spectra measured with two close temperatures. The unusual Eu luminescence enhancement upon heating was observed for the first time for the complex with tetradentate O,N-type heterocyclic diamide ligand L, while an inverse phenomenon was observed with the Tb luminescence. The Eu luminescence enhancement was found earlier for various carboxylate complex salts, but not for heterocyclic coordination complexes. This allows the construction of a ratiometric luminescent thermometer in the range of 280–340 K using the ratio of luminescence intensities for Eu and Tb. The stability constants for the individual Eu and Tb complexes help us to understand the equilibrium in L:Tb:Eu complex system and shed light on plausible speciation in solution.

Authors: Billings Christopher , Siddique Ridwan , Liu Yingtao
Published: October 2023

Vat photopolymerization-based additive manufacturing (AM) is critical in improving solutions for wearable sensors. The ability to add nanoparticles to increase the polymer resin’s mechanical, electrical, and chemical properties creates a strong proposition for investigating custom nanocomposites for the medical field. This work uses a low-cost biocompatible polymer resin enhanced with multi-walled carbon nanotubes (MWCNTs), and a digital light processing-based AM system to develop accurate strain sensors. These sensors demonstrate the ability to carry a 244% maximum strain while lasting hundreds of cycles without degradation at lower strain ranges. In addition, the printing process allows for detailed prints to be accomplished at a sub-30 micron spatial resolution while also assisting alignment of the MWCNTs in the printing plane. Moreover, high-magnification imagery demonstrates uniform MWCNT dispersion by utilizing planetary shear mixing and identifying MWCNT pullout at fracture locations. Finally, the proposed nanocomposite is used to print customized and wearable strain sensors for finger motion monitoring and can detect different amounts of flexion and extension. The 3D printed nanocomposite sensors demonstrate characteristics that make it a strong candidate for the applications of human kinematics monitoring and sensing.

Published: October 2023

The solar drying process is a critical postharvest stage for preserving coffee quality and is widely used in coffee-producing countries. A descriptive exploratory study was carried out in zones with different annual solar brightness to determine the climate variability influence on solar drying. Variables related to the evolution of drying, physical and sensory quality, and the physicochemical characteristics of the Castillo® coffee variety were analyzed. Coffee quality was assessed by means of SCA protocol. An automatic system was designed to record variables inside the dryers and mass loss. The drying rates were different by climatic zone above and below 0.52%∙h−1. Drying time was significantly longer in less solar brightness zones (Wilcoxon test). An inverse linear relationship between rewetting percentage and bean moisture was observed. Regarding coffee quality, the average scores were 81.37 and 80.93 SCA points for the climatic zones with the lowest and highest solar brightness, respectively. The bean color, water activity, acidity, and fat content did not vary between climatic zones. The coffee quality was not affected by solar drying in contrasting climatic conditions, despite the differences in drying time. Solar drying behaviors were identified that allow for the development of strategies for improving the process efficiency and management of coffee.

Authors: Yang Yanhai , Wang Chonghua , Yang Ye
Published: October 2023

The utilization rate of reclaimed asphalt pavement is significantly low in the sustainable design process of asphalt roads. Numerous researchers have extensively investigated the recycling and utilization of reclaimed asphalt pavements from various perspectives. Molecular dynamics simulations could elucidate the diffusion phenomenon occurring at the molecular scale between virgin and aged asphalt interfaces. This review provides a comprehensive summary of the simulation methods and applications of molecular dynamics simulation in the interface diffusion problem between virgin and aged asphalt. Diffusion theory and model testing methods are discussed. The review proposes the basic steps of molecular dynamics simulation and summarizes the molecular models with the corresponding parameter settings of virgin asphalt and aged asphalt. Moreover, the current influencing factors on the interfacial diffusion problem of virgin and aged asphalt are discussed. The paper explores the validation parameters including density, viscosity, radial distribution function (RDF), glass transition temperature, and solubility parameters based on the existing research. Molecular dynamics simulation could simulate interface diffusion at a micro-scale and clarify the diffusion depth and influence range of different asphalts. The purpose of the study of molecular dynamics is to solve interface issues and advance optimization of reclaimed materials.

This review summarizes the latest progress and challenges of multi-omics for designing new treatments for human diseases, focusing on how to integrate and analyze multiple proteome data and examples of how to use multi-proteomics data to identify new drug targets. We also discussed the future directions and opportunities of multi-omics for developing innovative and effective therapies by deciphering proteome complexity.
Assessing the Impact of Credit Risk on Equity Options via Information Contents and Compound Options
Authors: Maglione Federico , Mancino Maria Elvira
Published: October 2023

This work aims to develop a measure of how much credit risk is priced into equity options. Such a measure appears particularly appealing when applied to a portfolio of equity options, as it allows for the factoring in of firm-specific default dynamics, thus producing a comparable statistic across different equities. As a matter of fact, comparing options written on different equities based on their moneyness does offer much guidance in understanding which option offers a better hedging against default. Our newly-introduced measure aims to fulfil this gap: it allows us to rank options written on different names based on the amount of default risk they carry, incorporating firm-specific characteristics such as leverage and asset risk. After having computed this measure using data from the US market, several empirical tests confirm the economic intuition of puts being more sensitive to changes in the default risk as well as a good integration of the CDS and option markets. We further document cross-sectional sectorial differences based on the industry the companies operate in. Moreover, we show that this newly-introduced measure displays forecasting power in explaining future changes in the skew of long-term maturity options.
Diamagnetic Screening in the Electromagnetic Turnout Switch for a High-Temperature Superconducting Maglev System
Authors: Gerasimenko Anastasiia A. , Peng Can , Lu Hao , Korchagin Vadim O. , Zhang Xiwen , Li Haitao , Deng Zigang
Published: October 2023

Maglev systems represent a cutting-edge high-speed transport technology, and turnout switches play a critical role in the creation of a highly branched network. There are two common types of turnouts for high-temperature superconducting (HTS) Maglev systems: mechanical and electromagnetic. Due to the many advantages, an electromagnetic turnout is a better choice for a Maglev system than a mechanical one. However, there is a difference in the distribution of the magnetic field over the turnout area and the permanent magnetic track, which cannot meet the safety requirements of the Maglev system. This article proposes a modernized design of an electromagnetic switch based on previously proposed optimization solutions by placing a diamagnetic screen between two electromagnetic poles of an electromagnet, thereby reducing the scattering fluxes between them. The method of diamagnetic screening and experimental methodology are described in this article. The experiment was carried out using a three-dimensional magnetic field scanner to provide results on the distribution of the magnetic field and the increase in the magnetic induction value over the electromagnet poles. Thus, this article provides valuable suggestions for improving the design of the electromagnetic turnout of HTS Maglev systems. Moreover, the proposed method can be applied to any magnetic device or electric machine with an open magnetic circuit.

Published: October 2023

Photoluminescent materials used on street and road pavements could absorb solar energy during the day and emit it at night, which will save energy and improve visibility with a consequent improvement in road safety. The aim of this study is to evaluate the luminance of different photoluminescent applications for pavements (bituminous mixes, mortars, and paints) in which strontium aluminate and glass beads were used. Sunlight was simulated with two bulbs, one LED and one UV bulb, inside a measuring apparatus specially developed for this work. The luminance of the different designed solutions was determined at different time periods after their excitation. The results obtained showed that luminescent paints can reach higher luminance than bituminous mixes and mortars. The colour of the base surface on which the paints are applied had a great influence on the obtained luminance, which increases with the aluminate and glass beads content. Among all the solutions evaluated, the paint made with 60% aluminate and 6% glass beads, spread on a white surface, allowed the highest luminance values to be obtained. This study leads to the conclusion that it is possible to achieve a good photoluminescent level while economising on the amount of materials necessary.

Published: October 2023

To assess wind energy potential in Northern Morocco, a validated approach based on the two-parameter Weibull distribution is employed, utilizing wind direction and speed data. Over a span of two years, from January 2019 to December 2020, measurements taken every 10 min are collected. This study is centered on a comprehensive and statistical analysis of electricity generated from a wind farm situated in the Tetouan region in Morocco. This wind farm boasts a total capacity of 120 MW, comprising 40 wind turbines, each with a 3 MW capacity, strategically positioned along the ridge. Among the available techniques for estimating Weibull distribution parameters, the maximum likelihood method (MLM) is chosen due to its statistical robustness and exceptional precision, especially for large sample sizes. Throughout the two-year period, monthly wind speed measurements fluctuated between 2.1 m/s and 9.1 m/s. To enhance accuracy, monthly and annual theoretical power densities were recalculated using the Weibull parameters and compared with actual measurements. This has enabled the detection of production disparities and the mitigation of forecast errors throughout the entire wind farm. In conclusion, over the two-year production period, turbines WTG 30 and WTG 33 displayed the most significant shortcomings, primarily attributed to orientation issues within the “Yaw system”.
Supporting Local Implementation of the European Green Deal through a Place-Based, Participatory Approach: Methodology for a Comprehensive Analytical Framework
Authors: Testi Andrea , Zetti Iacopo , Tarsi Elena , Fontana Cassandra , Gisotti Maria Rita , Rossi Maddalena
Published: October 2023

With the launch of the European Green Deal (EGD) in 2019, the European Union aims to become a global leader in the ecological transition. To implement sustainable policies at the local level, a place-based, analytical approach is a necessary prerequisite to understanding territorial specificities and adapting the EGD challenges to local conditions and opportunities. Moreover, the research acknowledges the key role of public participation and, thus, the need to construct innovative policies that involve citizens in this process. On this basis, our primary goal was to create a comprehensive, multipurpose, and non-context-specific analytical framework that could support ecological transition policies within the EGD through a place-based, participatory approach. After outlining the major features of the EGD and the place-based approach, this paper describes the steps that were taken to define the framework and select the types of data to be used. In response to the scarcity of methods adaptable to different scales, contexts, purposes, and target groups, we built upon the current studies on sustainability assessments and developed a novel analytical framework for territories ranging from municipalities to nations. This study suggests that a comprehensive, multidimensional territorial analysis—which can interpret and communicate environmental, socio-economic, and institutional specificities of territories—is decisive for bringing together local administrations and citizens, as well as meeting the challenges posed by sustainable development.

Published: October 2023

Climate change and low agricultural productivity are the major hurdles facing sorghum farming in the Lake Zone Region of Tanzania. However, there is limited information on the contribution of sustainable projects in greening the sorghum value chain in Tanzania. This study aims to analyze how to develop a resilient and sustainable sorghum value chain using a project approach. Primary and secondary data were collected and used. Primary data were collected using key informant interviews (KII) administered to the value chain actors using audio recordings and notes. Secondary data were obtained from project-related project documents, reports, publications, and conference proceedings. The audio recordings were transcribed into lengthy notes summarized for ease of interview theme identification. To enhance access to improved seeds and fertilizers and advisory services, a linkage between the agro-dealers (input suppliers), farmers, and extension personnel was established to improve farmers’ yield potential. Good agricultural practices, e.g., planting methods and pest management and improved seed varieties that were drought tolerant, early maturing, and high yielding, such as Macia and Tegemeo, were readily available in shops and promoted through the establishment of demo plots. Local aggregation of sorghum grain helped to ease transport-to-market logistics for farmers and contributed to lower transport costs. Mechanized threshing was promoted to ensure the high-quality crop is sold to the off-taker for premium prices and meets the export market requirements. We highlight the Lake Zone project experiences and lessons learned to demonstrate the potential for building resilience and sustainability of the sorghum value chain.

Published: October 2023

In recent years, teaching and learning practices have transformed greatly due to emerging technologies. Despite various pedagogical and technological innovations, the learning effectiveness of the new learning environments is still being debated. Systems thinking concepts and methods are needed regarding how to accommodate digital technology to optimize the efficacy of students’ learning, especially when student cohort specificities are addressed. For the purpose of this study, we used an empirical research design supported by a bibliometric analysis. Multiple regression using dummy coding of the predictor variables was conducted to compare the prediction models across different groups of first-year students, while a sequential mediation model was used to examine the students’ perceptions of systems thinking, engagement in the design course, and information communication technology (ICT) self-concept in relation to academic achievements. The results indicate that systems thinking centered around the understanding of feedback behaviors and causal sequences in the system has a direct effect on the design outcome and ICT self-concept related to problem solving and cognitive engagement, while, indirectly, systems thinking also mediates achievement in design courses. The ICT self-concept related to problem solving and cognitive engagement mediates the relationship between systems thinking and design course achievement. This study highlights the importance of leveraging learning system dynamics factors in diverse student cohort design courses and provides implications for developing a high-performance digital education sustainable ecosystem.

Published: October 2023

The treatment of petroleum refinery wastewater (PRWW) is of great interest in industrial wastewater management. This wastewater contains a diverse concentration of contaminants such as oil and grease, petroleum hydrocarbons, phenols, ammonia, and sulfides, as well as other organic and inorganic composites. Refinery wastewater treatment has been attempted through various processes, including physical, biological, chemical, and hybrid methods, which combine two or more techniques. This review aims to summarize current research studies involved in the treatment of petroleum refinery wastewater using conventional, advanced, and integrated treatment techniques. Furthermore, it critically highlights the efficiencies and major limitations of each technique and the prospects for improvements. Several conventional treatment techniques (basically, the physicochemical and biological processes) are discussed. In this context, advanced oxidation processes (AoPs), especially electrochemical oxidation and photocatalysis, as well as integrated/hybrid processes are found to be effective in removing the recalcitrant fraction of organic pollutants through their various inherent mechanisms. These techniques could effectively remove COD and phenol concentrations with an average removal efficiency exceeding 90%. Hence, the review also presents an elaborate discussion of the photocatalytic process as one of the advanced techniques and highlights some basic concepts to optimize the degradation efficiency of photocatalysts. Finally, a brief recommendation for research prospects is also presented.

Published: October 2023

Previous scholarly investigations have mainly concentrated on examining water intake, particularly within the specific domain of coal mines. Nevertheless, the scholarly discourse lacks significant research on predicting water inflow in environments with complex multi-layer mineral distributions. The Yanlong mining area is a complex mine containing coal and bauxite. Forecasting the water inflow of bauxite deposits is crucial for designing mining drainage and formulating a mining plan in a coal-bearing rock series mining area. The water inflow on the roof and floor of bauxite was studied with various numerical simulation and analytical methods (such as the big well method). The hydrogeological conceptual and numerical model of the mining area was established by the MODFLOW module in Groundwater Modeling System (GMS (7.1)) software, and the measured groundwater level was identified and verified in the model. The results show that the model average values of R2, Ens, and PBIAS are 0.86, 0.81 and 2.71, respectively, indicating that the established numerical simulation model can accurately forecast water inflow into the aquifer. Taking No. XII orebody in the eastern Songshan Mining area as an example, a virtual well group consisting of 12 wells was set up, and the numerical model forecast a water inflow of 71,500 m3/d from the Taiyuan Formation aquifer in the bauxite ore roof, which was lower than the value predicted by the large well method (72,786.66 m3/d). The numerical method predicted an average water inflow of 59,000 m3/d and a maximum water inflow of 82,600 m3/d from the Majiagou Formation in the bauxite ore floor. A dependence has been established that the numerical method estimates water inflow with accuracy. Additionally, the model predicts future mining water inflow, and also provides a standard framework for estimating inflow in similar mining conditions.
ANALYSIS OF THE EXPERIENCE OF INTRODUCING GAMIFICATION INTO THE EDUCATIONAL PROCESS
Authors: Verbovetskyi Dmytro
Published: October 2023

The statement of basic materials. Analyzing works in the field of gamification of education, it can be said that the use of gamification methods helps bring the educational process closer to real practical activity. This approach allows students to learn the material more effectively and improve their skills. Game technologies are closely related to the self-realization of students' personalities, significantly increase the quality of education, and their implementation in the educational process is an important element in the development of the student's professional competencies. The game should be considered one of the types of interactive learning methods, which, among other things, aims to implement the psychological processes of student self-realization. During the pedagogical game, students take an active position, and their interest in the object of knowledge increases. At the same time, the teacher's role is transformed, he becomes the organizer, the leader of the process. To implement pedagogical interactive games in the educational process, the teacher is required to be competent in the use of appropriate technologies.
HESYCHASTIC TRADITION AS A SOURCE OF UKRAINIAN CORDOCENTRISM
Authors: Ihnatiev Vitalii
Published: October 2023

The statement of basic materials. The history of the adoption of Christianity by Kyivan Rus from the very beginning shows close ties with the monastic republic on Mount Athos. Researchers testify that Mount Athos was already the center of enlightenment and culture of Kyivan Rus. Only in this way does it become clear that Antony Pecherskyi was not a historical accident that suddenly fell from the sky like a star. Not only in Kyiv, but also in other cultural and political centers, monasteries appear in the context of the Athos heritage. XV century became catastrophic for the Byzantine Empire. But Athos retained relative autonomy. In the 16th century it is Volyn that becomes the spiritual and educational center of connection between the Ukrainian land and Mount Athos. The decline of Byzantium also affected the history of Ukrainian lands. The gradual strengthening of the Polish-Lithuanian Commonwealth led to the beginning of projects to absorb Orthodox culture. The Union of Brest in 1596 provoked a movement of Orthodox spiritual and cultural resistance. And Athos, with the tradition of the Hesychasts, fulfilled his spiritual mission. The Athos influence on the literary works of Ukrainian figures was direct. S. Shumylo claims that Elder Ioann Vyshenskyi was the brightest personality of the Orthodox movement in Ukraine in the 17th century. His spiritual and literary work is a century ahead of the forerunners of the “philokalic revival” in Orthodoxy of the 18th-19th centuries. The works of I. Vyshenskyi are deeply imbued with ascetic and hesychastic motifs. But he was not only an experienced practitioner of the incessant Jesus prayer, but also tried to instill the hesychastic tradition in his homeland. It was from this that he wanted to build a spiritual and educational system in Orthodox monasteries according to Athos customs. The Ukrainian hesychastic revival had not only a religious and cultural-political influence. He was a statesman. The direct influence on the formation of Ukrainian statehood is confirmed by the blessing and, in fact, the legitimization of the “holy war” for the defense of Orthodoxy by the well-known Aphonite Patriarch of Constantinople Athanasius, who twice met with Bohdan Khmelnitsky and who ended his life in the Cossack Mgar monastery. The participation of Aphonites not only in the spiritual, but also in the political life of Ukraine was systematic and widespread. The 17th - 18th centuries also had a significant influence of the hesychastic tradition on all levels of Ukrainian society, from the spiritual and political elite to the masses. This is what can explain the phenomenon of H. Skovoroda.
CRITICISM OF SOCIAL CONSTRUCTIVISM IN THE POST-METAPHYSICAL THEOLOGY OF COMMUNICATION BY O. FILONENKA
Authors: Lozovytskyi Vasyl
Published: October 2023

The statement of basic materials. As a result of the critical achievements of the representatives of the linguistic and pragmatic turns of the 20th century, the belief that knowledge and social practices are embedded in language was established, and this makes them so inseparable that we begin to see reality as the result of cognitive and social construction. They recognize the distance between the world and consciousness, between language and the objectivity of the world, which make the problem of encountering the real impossible.
We investigated that the formation of O. Filonenko's postmetaphysical position was influenced by J. Derrida, J. Caputo, Zh.L. Marion, H.U. Humbrecht, J. Milbank. Under their influence, O. Filonenko questions the use of social constructivism as a universal social-humanitarian methodology and theological methodology

Published: October 2023

School reading lists are an essential factor influencing understanding the content and form of various types of texts: artistic, non-artistic, and electronic texts of an everyday nature among Czech technical secondary school pupils. The research aims to determine by analysing eight key school documents whether recommended school lists of texts for study at secondary technical schools are published electronically on schools' websites in the Moravian-Bohemian and Olomouc Regions of the Czech Republic. A partial goal is to determine whether school reading lists contain different types of texts and whether pupils at technical secondary schools understand information with a professional, artistic, media, etc., focus. A quantitatively oriented questionnaire survey through the lens of 523 pupils from 5 Czech secondary technical schools investigated what factors influence the reader's understanding of printed and electronic texts. The research results showed that Czech secondary school pupils like working with informal texts on social networks, frequently require help understanding texts of an administrative nature, and rarely work with texts from everyday life at school. The average to below-average level of reading and digital literacy among Czech 15-year-old pupils was also highlighted by the PISA 2018 international research.

NUMERICAL MODELLING OF REINFORCED CONCRETE FRAMES RETROFITTED WITH BUCKLING RESTRAINED BRACE INCORPORATING STEEL AND SUPERELASTIC SHAPE-MEMORY ALLOY CORES
Authors: Rocha Pedro Alexandre Guimaraes , Palermo Dan
Published: October 2023

The numerical response of one-storey reinforced concrete frames designed following design standards before the enactment of modern seismic provisions was investigated in this study using the nonlinear finite element method. An unbraced frame and two frames retrofitted with a buckling restrained brace (BRB) incorporating either a stainless steel or chrome molybdenum core bar were modelled. The nonlinear static reverse cyclic loading performance of the frames was assessed. Modifications to the BRB are proposed to mitigate deficiencies identified with the original BRB and steel core bars. The modified BRB incorporating a superelastic shape-memory alloy (SE-SMA) core bar was further modelled. The results illustrate the benefits of implementing SE-SMA as a retrofit strategy to control permanent displacements. The modified BRB with a SE-SMA core exhibited improved lateral strength and displacement capacities relative to the frames retrofitted with steel cores and the control bare frame.

Reconversiones militantes: del catolicismo tercermundista hacia diversas formas de organización político-social en la ciudad de La Plata (1960-1990)
Authors:   , Porta Fernández Pedro
Published: October 2023

En esta tesis abordamos los procesos de reconversión de la militancia del catolicismo tercermundista platense entre los años sesenta y principios de los noventa. Las militancias son un elemento central para dar cuenta de los fenómenos sociopolíticos contemporáneos reconociendo la diversidad de sus recorridos biográficos y organizacionales. Las transformaciones abordadas marcan una serie de reconfiguraciones del accionar político y de las militancias con repertorios y sentidos variables, donde las distintas dinámicas son analizadas en su trama espacio-temporal desde una perspectiva que pone de relieve un enfoque multiescalar, teniendo en cuenta los efectos recíprocos de los escenarios socio-políticos, de las redes de sociabilidad y las trayectorias biográficas. Partiendo de los procesos de politización y radicalización de la sociedad en general, y de sectores católicos en particular, acontecidos en los sesenta-setenta como usina militante, se recorrieron las trayectorias biográficas de estos militantes del catolicismo tercermundista platense. Esto se llevó adelante a partir de un abordaje multimodal que combina historias de vida y trabajo con fuentes documentales, que permitieron reconstruir los entramados y las transformaciones de estas militancias. Cada uno de los momentos fueron descriptos y analizados en sus especificidades y en íntima relación con una mirada de mediano plazo que permitió recorrer las continuidades, rupturas y reconversiones acontecidas que entretejieron tramas que motorizaron la comprensión de diversos procesos socio-políticos. En la descripción de los fenómenos se puso especial foco en ciertos ejes que recorren sinuosamente los diversos períodos, como la profesionalización y territorialización de las militancias, a partir de los sujetos que participaron de un modo o de otro en ellos. De esta forma, es posible dar cuenta de las experiencias y los procesos que componen el cuadro empírico de estos recorridos en su politización con sus expresiones peronizante, comunitaria y radicalizada; sus exilios, repliegues, remanencias y desapariciones durante la dictadura y su (re)inserción desde la vuelta de la democracia en las tres modalidades de reconversión militantes: político-partidaria, territorial y profesionalizada. Estos procesos fueron analizados vinculando las distintas escalas de la categoría reconversión militante: macro, meso y micro y su perspectiva diacrónica de mediano plazo. A partir de esta investigación reconstruimos estas militancias y sus aportes a los diversos procesos socio políticos a lo largo de las tres décadas propuestas.

Стрімкий ріст вантажних перевезень, зорієнтований, головним чином, на перевезення зерна з поля до місць зберігання або до портів, складає основну частку в відсотковому співвідношенні в перевезеннях вантажів подібного типу. Дороги загального користування, особливо ті, де відбувається активний рух без можливості та дозволу дорожніх знаків об’їхати той чи інший проміжок, мають великий влив на стан транспортного засобу. Одночасно із цим, вплив транспортного засобу відбувається взаємним чином і на дорожнє покриття. Якщо говорити про структурні елементи автопоїзда, цілі дослідження яких закладалися, до це такі основні елементи, як мости, рама, ресори, підвіска, колеса тощо. Разом із вище сказаним, дослідження мають свій прямий зміст лише при експлуатації з причепом. Дія такого виду навантаження на автомобіль призводить до зміни коливань як по частоті, так і за амплітудою. Тому, в дослідженні показано результати теоретичного моделювання коливань над колесами як правого, так і лівого бортів транспортного засобу за навантаження його над мостом транспортного засобу, над мостом причепу, а також між мостами автомобіля та причепа. В результаті проведеного ряду досліджень, можна зробити висновок, що виникнення коливань причепу при його завантаженні, наприклад, зерном, призводить до формування коливань над колесами у досліджуваного транспортного засобу. Закономірним є той факт, що найбільші з коливань за частотою та амплітудою спостерігаються за навантаження причепа над його мостом. Аналогічним чином, найбільші частота та амплітуда коливань відбувається і над мостом автомобіля. Мінімальні ж, за значеннями амплітуди і частоти, коливання спостерігаються за навантаження причепа між його мостами.

La creciente demanda de pacientes en busca de restauraciones estéticas subraya la importancia de comparar los parámetros generales estandarizados con las técnicas empleadas por diversos profesionales odontológicos. Este estudio se centró específicamente en la aplicación de resinas compuestas en la obturación de 20 órganos dentarios afectados por caries de grado 1. La metodología adoptada es descriptiva explicativa, apoyada en datos recopilados de la literatura y un cuestionario estructurado conforme a la NOM-004-SSA3-2012. Además, se realizó una anamnesis detallada a cada paciente con el propósito de integrar consideraciones sobre las necesidades preventivas de asepsia y antisepsia en el tratamiento. El contraste de los datos revela que la nanotecnología está desempeñando un papel significativo en el desarrollo de nuevos biomateriales odontológicos. Es crucial tener en cuenta factores específicos, como patologías individuales y elementos que puedan interferir con el protocolo de colocación de composites. Este análisis comparativo entre los parámetros oficiales y las prácticas actuales ofrece una perspectiva valiosa sobre las tendencias y avances en el campo de las restauraciones estéticas con resinas compuestas.

Published: October 2023

O Programa de Integração da Educação Profissional com a Educação Básica na Modalidade de Educação de Jovens e Adultos (PROEJA) foi criado objetivando promover a oferta da educação básica a Jovens e Adultos na Rede Federal de Educação, ao mesmo tempo em que tornou possível pensar a oferta de formação para o mundo do trabalho, com os princípios e concepções de uma formação humanista, integradora do trabalho, ciência e cultura. Mas é possível ainda integrar a essa concepção os aspectos as histórias de vida, constituintes da existência e parte também da formação humana integral. Nesse sentido, o estudo objetivou investigar sentidos de formação profissional que emergem das Histórias de Vida de 14 estudantes do Curso Técnico Integrado em Aquicultura do Programa Nacional de Integração da Educação Básica com a Educação Profissional na Modalidade de Jovens e Adultos – PROEJA, ofertado no Instituto Federal de Pará, Campus Tucuruí como fundamento para uma proposta de formação. A metodologia adotada foi a História de Vida em quatro fases, com base em Josso (2010) e adaptadas: 1) Introdução à construção da História de Vida; 2) O “caminhar para si” como proposta de reflexão sobre a trajetória de vida e formação profissional; 3) O que minha História de Vida revela sobre a minha formação; e 4) Balanço do processo formativo. A entrevista narrativa em grupo foi a técnica empregada para a coleta das fontes. Para a análise, utilizou-se a Análise Interpretativa-Compreensiva em três tempos (SOUZA, 2006). Como resultados, sentidos de formação emergiram das narrativas dos estudantes perpassando as fases da infância, juventude, fase adulta, revelando experiências que contribuíram para o retorno à escola no Curso Técnico Integrado em Aquicultura.
Spin-filter device using the Zeeman effect with realistic channel and structure parameters
Authors: Komatsu Soh , Akabori Masashi
Published: October 2023

We have theoretically calculated the performance of a Zeeman-type spin polarizer, which consists of ferromagnetic (FM) and metal–insulator–semiconductor (MIS) gate nanostructures on top of an InAs two-dimensional electron gas (2DEG) channel. For the calculations, we have taken a realistic electron concentration, electron effective mass and the effective g-factor of the InAs 2DEG into account. In addition, we have assumed realistic FM and MIS structure sizes by conventional electron beam lithography. In the calculations, we have demonstrated clear oscillation of spin polarization over ±85%. Furthermore, we have shown that it works not only as a spin-polarized current generator but also a detector. In addition, we have proposed a novel spin-filter device utilizing the Zeeman-type spin polarizers. We have found that its conductance characterization allows us to evaluate the operation of Zeeman-type spin polarizers. We expect the Zeeman-type spin polarizers and spin-filter devices to open up a new field of spintronics.
Flaws in the Authenticated Lesson Plans in the Department of Literature and Languages through the Lens of Trainee Teachers in Zambian Secondary Schools
Authors: Siame Pethias
Published: October 2023

The paper presents common flaws in the lesson plans which were authenticated by Heads of Department (HoDs) in the Department of Literature and Languages across Zambia for student teachers from Kwame Nkrumah University who underwent their teaching experience in 2020 and 2022. A flaw is synonymous to defect, fault and pitfall which should be viewed as a challenge or problem which requires immediate attention and possible solutions. Teaching experience allows trainee teachers to apply theoretical knowledge and skills gained during their course of training. The study employed Critical Discourse Analysis framing to account for flaws in the authenticated lesson plans. Qualitative approach, observation and document analysis methods were adopted. Thematic and descriptive concepts were used to analyse the data. The study shows that some mentors of students on teaching experience did not guide the trainee teachers well. In addition, some HoDs did not take keen interest to check the nature of lesson plans before authenticating them. Lesson plans lacked brainstorming during introductions, had disoriented developments which lacked class and individual activities. It is recommended that HoDs conduct thorough discourse analysis of what they authenticate.
