Forms of Interaction Between a Primary School and the Family of a Student with a Statement of Special Educational Needs in Inclusive Education
Authors: Wójcik Katarzyna
Published: January 2025

Inclusive education, along with integrated and special education, is one of the forms of education for students with statements of special educational needs, which in Poland can be issued due to certain types of developmental dysfunctions. It presupposes that students are educated in mainstream schools, with the smallest possible repertoire of special interventions. In the educational and therapeutic process of this group of students, parents play an important role, so the interaction between the school and the student’s family is essential. The present study addresses the issue of the primary school’s interaction with the family of a student with a statement of special educational needs. The focus of the research was on forms of collective interaction. The results of the survey indicated that parents of students with statements of special educational needs had little involvement in collective forms of interaction with the school. One of the main issues exposed in the study is parental education as one form of interaction.

Published: January 2025

The 2022 PISA results show a high level of functional illiteracy among Romanian students: 42% of Romanian students did not reach the second level in literacy tests. (OECD, 2023) Studies identified in the literature indicate the great importance that emergent literacy skills have on the future acquisitions that students achieve in the educational process, especially for students with low socio-economic status. For a teacher, to facilitate the development of these competences, it is necessary to apply appropriate methods and strategies adapted to the particularities of the pupils. Given these considerations, we set out in this study to investigate the impact of an intervention aimed at emergent literacy on first grade students from disadvantaged socio-economic backgrounds. The research carried out is a quantitative quasi-experiment. The research sample consisted of 15 first graders from disadvantaged socio-economic backgrounds, some of them bilingual and not enrolled in kindergarten. For data collection, a literacy assessment booklet was used as a literacy assessment instrument, used as a pre-test and post-test. In between the two tests there were didactic activities in which the researchers worked with each participant, on an individualized basis, on all the essential aspects related to emergent literacy. The findings of this study show that the pupils who participated in the remedial activities aimed at emergent literacy showed, at the end of the intervention, an improvement in literacy competenceon all the dimensions targeted by the research instrument.

Authors: Gil Alina , Głębocki Rafał , Nowacka Urszula
Published: January 2025

The constant changes in today’s world, in almost all areas of life, are forcing individuals to continually upgrade their education, expand their competencies to adapt to a changing and unpredictable reality, and efficiently take advantage of the many opportunities provided by modern technology. Learning management systems (LMS) like Moodle, Canvas and Blackboard are becoming increasingly popular in educational institutions, highlighting the growing integration of technology in education. Integrating cloud services such as Google Workspace and Microsoft 365 has dramatically improved the capabilities and accessibility of distance education. These platforms offer tools that enable real-time collaboration, information sharing and effective communication between teachers and students. Today–thanks to constant access to the Internet–learners have a variety of ways to (self-)learn formally and informally, including through mobile devices or social or information services. The article describes the concept of MOOCs–these are quick courses organized in a virtual space to acquire knowledge, skills and social competencies in an easy and accessible way, available to everyone, regardless of the age of potential participants, their qualifications, location or possession of specialized software–and an example of the application of the MOOC concept in adult education which is the GSmart MOOC tool developed within the framework of the international Erasmus+ project entitled Generation: Smart. Social Competences Transmedia Bridge To Cultivate A New Culture For Cross-Generational Collaboration (GSmart) was implemented by us. The emergence of MOOCs, such as GSmart, in adult education underscores a significantshift toward more inclusive, flexible and interactive learning environments. The continued evolution and adoption of MOOCs will be crucial in shaping a future in which lifelong learning is integral to personal and professional development. Moreover, the example of our course may encourage others to apply the concept in various other possible ways.
Career Counsellor’s Assistance in Choosing a Technical School in the Opinion of Parents
Authors: Pardej Katarzyna
Published: January 2025

This article presents the results of the author’s research, which aimed to identify how parents perceive career Counsellor’s assistance in the choice of post-primary school and to what extent labour market forecasts are considered in the decision-making process. The research results correspond with the view presented from the perspective of their children published in the article "Career Counsellor’s Assistance to Students in the Choice of Post-primary School and Profession Sought in the Labour Market" (Pardej, 2024a). The qualitative research used the interview method. The analysis of the research material was conducted using the MAXQDA 2022 program. The research sample consisted of parents of first-year students of Warsaw technical schools studying the professions of the future N=53 (Monitor Polski, Journal of Laws, 2023, item 145).Regarding the choice of secondary school and profession, parents and their children most often use the services of a career counsellor at primary school (40 coded segments). In many families, however, the decision-making process occurs without consulting a career counsellor (28 coded segments). According to parents, their children are more likely to seek the help of a career counsellor at school than at the psychological-educational counselling centre because of the long-term contact, followed by the child’s openness to cooperation. Parents see many areas for improvement regarding the competence of career counsellors and the lessons they teach. Parents have a (usually everyday) knowledge of the labour market and desired occupations (30 coded segments). If they check labour market forecasts, they often do so together with their children (12 coded segments) or give up this activity (23 coded segments). In contrast, occasionally, they do so alone (either children or parents).

Authors: Bilarzewska Julia , Grunt-Mejer Katarzyna , Ladra Sara , Neter Julia , Marciniak Izabela
Published: January 2025

The survey included 341 people aged 18–30 who answered the following questions: What sex-uality-related question have you wanted answered recently? Were you able to get an answer to this question? Where did you try to find the answer to your question? The sources of knowledge about sexuality that the respondents valued were also checked. The responses were subject to thematic analysis. Analysis of the responses revealed five major topics containing 39 themes. The topics were sexual health (the most frequently sought answers concerned contraception, physiology and anatomy), sexual activity (the most frequent question concerned anal sex), sexual pleasure (the most frequent theme concerned orgasm), psychology and relationships (the most frequent theme concerned the quality of desire and sex in long-term relationships), and socio-cultural knowledge (the dominant theme concerned genderidentity and sexual orientation). The most common source of knowledge is the Internet, mainly social media. The results indicate a significant need for even elementary education on anatomy, physiology and contraception. Questions related to the impact of pornography and the need for respondents to understand rapid social changes, including diverse orientations and identities, are also prevalent.

Authors: Hrabal Jiří
Published: January 2025

Članak Vitez Eduard Griez de Ronse i njegova „češka“ pisma iz Dal-macije izvorni je biografski portret viteza Eduarda Grieza de Ronsea, koji je u Češ-koj studirao i proveo mladost, a radni je vijek proveo uglavnom u Dalmaciji kao viso-ki dužnosnik Austrijske Monarhije te je bio zaslužan za razvoj uprave, infrastrukture i školstva u Dalmaciji (posebice u Splitu) u razdoblju od 1826. do 1849. Njegova pisma iz Dalmacije, objavljena 1834. godine u časopisu „Česká wčela”, prvi su pu-topisni tekstovi iz Kraljevine Dalmacije objavljeni na češkom jeziku. Griezov potpuni biografski portret, koji do sada nije nastao ni u češkoj ni u hrvatskoj sredini, napisan je na temelju heurističkog istraživanja tadašnjeg tiska i Griezove ostavštine.

Published: January 2025

Josip Milaković (1861–1921) byl chorvatský básník, publicista, sběratel lidových písní a překladatel působící v bosenském Sarajevu. Mezi jižními Slovany popularizoval českou a lužickosrbskou poezii. Dopisoval si s významný-mi osobnostmi českého a lužickosrbského kulturního života. K nejvýznamnějším českým osobnostem patřil propagátor slovanské vzájemnosti Adolf Černý (1864–1952), který se s J. Milakovićem osobně seznámil při návštěvě Sarajeva 14. března 1899. A. Černý také Milakoviće přivedl k zájmu o Lužické Srby a později zprostřed-koval, byť jen písemný, kontakt s nejvýraznější postavou lužickosrbského národ-ního hnutí jazykovědcem Arnoštem Mukou (1854–1932). Veškerá tato korespon-dence se nachází v literární pozůstalosti Josipa Milakoviće v Historickém archivu města Sarajevo.

Srednjovjekovni bohemizmi u hrvatskoj glagoljskoj književnosti
Authors: Kramarić Martina
Published: January 2025

Obično se u povijesti hrvatskoga jezika pojava bohemizama povezuje s 19. stoljećem, i to najčešće s Bogoslavom Šulekom i njegovim rječnicima. Među-tim u hrvatskoj srednjovjekovnoj književnosti postoji cijeli niz djela prevedenih sa staročeškoga jezika koja su nastala za boravka hrvatskih svećenika glagoljaša u Pragu, predjelu Emaus, od 1346. do 1419. godine. U tim se prijevodima pojavljuju i utjecaji češkoga jezika, koji su najučestaliji i najuočljiviji na leksičkoj razini. Riječ je stoga o češkome leksiku koji su glagoljaši prevoditelji nehotice unosili u svoj pri-jevod zbog jezične sličnosti dvaju slavenskih jezika ili zbog nedovoljna poznavanja značenja češkoga leksika. S obzirom na to da se taj leksik nije zadržao u hrvatskome jeziku te da je prema teoriji dodirnoga jezikoslovlja riječ o jednokratnome posuđiva-nju, govorit ćemo o srednjovjekovnim bohemizmima. Na temelju dosad analiziranih tekstova starohrvatskih prijevoda sa staročeškoga jezika metodološki ćemo odredi-ti smjernice za istraživanje takva utjecaja češkoga jezika s obzirom na dosadašnja istraživanja. Također ćemo na temelju pojedinih primjera češkoga leksika u tim pri-jevodima analizirati razlog pojavljivanja i prikazati način prilagodbe češkoga leksika te navesti čestotnost pojavljivanja istoga leksika u različitim prevedenim djelima.

Češko-hrvatske veze u kontekstu razvoja pijanističke djelatnosti i institucionalizacije glazbenoga školstva u Zagrebu tijekom 19. i početkom 20. stoljeća
Authors: Mičija Palić Martina
Published: January 2025

Razvoj pijanističke djelatnosti i glazbenoga školstva u zagrebač-koj sredini tijekom 19. i početkom 20. st. u ovomu se radu sagledava iz rakur-sa češko-hrvatskih glazbeničkih migracija, koje su uvelike utjecale na cjelokupnu glazbenu scenu Zagreba. S obzirom na to da je u navedenu razdoblju stožerna glazbena institucija bio Hrvatski glazbeni zavod, nastojat će se analizirati dopri-nos pojedinih glazbenika – skladatelja, pijanista i glasovirskih pedagoga – domi-nantnih kulturnih posrednika, koji su svoju djelatnost ostvarili u okviru te institu-cije, naročito njezine klavirne učione. U fokusu češko-hrvatskih glazbenih doticaja ponajprije će se razmatrati utjecaj glazbenika češkoga podrijetla koji su djelovali u Zagrebu, a potom i hrvatskih glazbenika, koji su se najčešće školovali na Kon-zervatoriju u Pragu. Time će se dokazati značajan doprinos češko-hrvatskih veza razvoju zagrebačkoga pijanizma, poglavito u posljednjim dekadama 19. i na po-četku 20. stoljeća. Jednako tako, s obzirom na to da su se do osnutka Muzičke akademije u Zagrebu 1921. godine zagrebački glazbenici u najvećoj mjeri školo-vali u Beču i Pragu (nešto poslije u Budimpešti, Berlinu i Parizu), u formativnom ishodištu Zagrebačke pijanističke škole, među ostalim, pronalazimo i utjecaj Češ-ke pijanističke škole. Poredbom utjecaja različitih europskih pijanističkih škola i njihovih predstavnika – pijanističkih interpreta i pedagoga – na razvoj pijanizma u Zagrebu u kontekstu izvodilačke i pedagoške djelatnosti potvrdit će se značaj češkog doprinosa kao važnoga pokazatelja fluidnosti glazbenih češko-hrvatskih kulturnih razmjena.

Published: January 2025

Bees (Hymenoptera, Anthophila) are considered the main pollinating insects. However, in several regions of the planet, their populations have been decreasing and, consequently, the benefits of the pollination ecosystem service have decreased, both in natural and agricultural areas. Pollination is an important biological phenomenon, acted free of charge by biodiversity and necessary for plant reproduction and maintenance of plant genetic variability. In Brazil, it is estimated that there are 3,000 species of bees divided into groups according to the level of socialization. This work began in June 2024 and aims to monitor native bee species in forest fragments and areas in different stages of recovery with a history of use in livestock farming, located in the Experimental Field of Embrapa Gado de Leite, in the municipality of Coronel Pacheco-MG. Captures were performed using different methodologies: passive Malaise trap; passive essences traps containing vanilla, eugenol, eucalyptol and methyl acetate as attractive odorous baits; active collection with entomological net in flowering plants. A total of 12 bee species have been collected to date, which indicates that the study area has the potential to present native bee diversity compatible with other areas of Atlantic Forest sampled in Brazil. The species list tends to increase based on new surveys, which will be conducted in other phytophysiognomies of the landscape still not covered in this phase of the experiment. Among the species collected, only Apis mellifera Linnaeus (1758) is exotic, which was introduced to Brazil during colonization. Thus, almost all of the species collected in the transition area are native to Brazil. These species provide important ecological services in the municipality, such as pollination of wild and cultivated species.

La variación de (-s) en contextos de bilingüismo presenta un grado de complejidad en el que convergen distintas áreas del saber. En este trabajo se estudia la sibilante en coda silábica en el español de San Andrés como segunda lengua, para dilucidar parte de los cuestionamientos que surgen de una variedad poco explorada que correlaciona multiplicidad de factores. Esta variable se ha empleado en la diferenciación de diasistemas, la clasificación de áreas dialectales y, en el caso de una segunda lengua, en la determinación de la adquisición de la norma sociolingüística. Se analizan 3600 casos extraídos de conversaciones semidirigidas obtenidas de 36 hablantes bilingües criollo-español. Los resultados evidencian que la variedad estudiada favorece la forma fiel al léxico. La variación de (-s) está restringida por el grado de apertura, por evitar la heterosilabicidad vocálica y revela tendencias sociolingüísticas reportadas previamente. La reagrupación de la muestra reveló datos que coinciden con variedades del español de Colombia, lo cual se relaciona con la adquisición de los patrones de variación para (-s) propios de una variedad meta.
Personalidad y carga emotiva en la traducción de testimonios de cáncer de mama
Authors:   Universidad de Murcia, Cifuentes-Férez Paula , Pina Cárceles Carmen María ,   Universidad de Murcia
Published: January 2025

Este artículo de investigación se centra en analizar el impacto o la influencia de la personalidad y la carga emotiva de testimonios sobre cáncer de mama en la precisión y la calidad de las traducciones. Para ello se diseñó un estudio experimental en el que un grupo de traductores tuvo que leer y traducir dos testimonios sobre cáncer de mama (uno con valencia positiva y el otro, negativa), además de cumplimentar una serie de pruebas psicométricas. Con base en la literatura existente, se postularon estas tres hipótesis: 1) las traducciones del texto con carga negativa serían mucho más precisas que las del texto con carga positiva; 2) los traductores altamente sensibles producirían mejores traducciones, pero presentarían niveles de ansiedad más elevados; y 3) aquellos con un mayor autoconcepto obtendrían peores resultados en ambas traducciones. Los resultados obtenidos mostraron que, en efecto, las traducciones del texto negativo eran mucho más precisas en lo que se refiere a la transmisión del sentido y la terminología. En lo que respecta a la sensibilidad, los participantes altamente sensibles tuvieron mejores resultados solamente en la traducción del texto positivo. En cuanto al impacto del autoconcepto, nuestra hipótesis solo se corroboró para las traducciones del texto negativo.

Additive manufacturing has a good application prospect in aerospace, medical implantation and other fields, but the molding surface quality is poor, without post processing can not meet the requirements of high service, polishing processing is a key link in the high-performance metal additive manufacturing technology chain. This paper summarizes the characteristics of the ladder effect, the high roughness of the forming surface. In recent years, additive manufacturing technology, also known as 3D printing, has been highly valued by aviation enterprises for its unique advantage in rapid prototyping, particularly for complex metal parts. However, due to the layer-by-layer growing process of 3D printing, the built parts often have poor surface roughness and are not suitable for practical use without post-treatment. Based on this foundation, the primary focus of research in the field of additive manufacturing for metal parts polishing includes electrochemical, laser, and abrasive flow polishing technologies. The progress in these areas is examined with consideration given to various manufacturing processes, different types of metal powder materials, and diverse structures (such as porous structure and high aspect flow channels) found in additive manufacturing samples. This review summarizes the research findings related to surface roughness, material removal, surface residual stress, profile accuracy retention, and other technical indicators associated with the polishing process for additive manufacturing metal parts. Finally, the paper discusses potential future developments in polishing technology for 3D printed metal parts.

The escalating scarcity of potable water in remote and arid regions necessitates increased reliance on sustainable solutions, notably solar stills. The imperative need to achieve high productivity and peak hour efficiency in these devices is critical to effectively addressing water shortages. This study explored modified solar still designs aimed at improving the productivity and peak-hour efficiency of the water desalination process. The experimental investigations involved various parameters, including water depth (10, 20, and 30 mm), mass flow rate (10, 15, and 20 kg/h), and glass thickness (4, 5, and 6 mm) for both traditional and stepped solar stills. The experimental layout followed an L18 orthogonal array. It was structured with 21×33 = 18 combinations, ensuring comprehensive coverage of the factors and levels involved, and the outputs were systematically examined using the Taguchi approach to identify the optimal parameter values. Stepped solar stills have emerged as superior, demonstrating higher peak-hour efficiency and productivity than traditional solar stills. The most influential parameters, ranked by eff ectiveness,were the type of solar still, water depth, glass thickness, and mass fl ow rate. The optimal conditions for achieving maximum productivity (3881 ml) and peak hour effi ciency (22.03%) were identifi ed, including a stepped solar still, 10 mm water depth, 15 kg/h mass fl ow rate, and 4 mm glass thickness. The experimentally measured values were closely aligned with the predicted values, verifying the accuracy of the Taguchi model with minimal error (0.81% in productivity and 0.49% in peak hour effi ciency).

Date palm leaf fibers are suitable for engineering applications due to their availability, inexpensiveness, and ecofriendliness. However, there is a risk of biodegradation in the long term. This paper explores date palm leaf fiiber (DPL) properties and the protection of the fibers from biodegradation to enhance their lifespan. To this end, two coating materials (bitumen and polyurethane) were used separately. Physical and mechanical tests were conducted to determine the most effective material to coat the DPL fibers. To comprehensively assess the performance of the coated fibers, their morphology was examined via microstructure analysis using scanning electron microscopy (SEM) and energy dispersive X-ray analyses (EDX) tests. This analysis encompasses their material properties, chemical composition, water absorption, and degradation, providing a thorough understanding of the protective coatings’ impact on the DPL fibers. The tensile strength test results revealed that the maximum tensile strength of the bitumen coated date palm fiber (DPLB) is 7.4 MPa. The tensile strength is two times greater than the polyurethane coated date palm leaf fiber (DPLP) and untreated date palm leaf fiber (UDPL). The results of the degradation test revealed that the weight loss percentage is equal to 45.5 and 25 in the case of the UDPL and DPLP fibers, and no loss in weight in the case of the DPLB fiber. Out of all the test results, bitumen is considered the best due to its ability to resist the attack of chlorides and sulfate ionspresent in groundwater on top of being cheap, simple, and efficient.

The integration of Lean Manufacturing (LM) and Industry 4.0 (I4.0), also known as Lean Manufacturing 4.0 or Smart Factory, is increasingly adopted by manufacturers for their effectiveness in reducing losses and improving efficiency. Despite their established benefits, there is a notable gap in comprehensive analyses regarding the integration of I4.0’s Manufacturing Execution System (MES) and Total Productive Maintenance’s Overall Equipment Effectiveness (OEE) within lean practices. Therefore, the purpose of this paper is to provide a comprehensive literature review offering thorough insights into the trends, applications, and impacts of Lean Manufacturing 4.0. Utilizing a systematic literature review, this research initially assesses 250 papers for bibliometric trends, narrowing down to 44 papers for content analysis. The bibliometric analysis reveals trends in Lean Manufacturing 4.0 publications, including historical series, publications across countries, highly cited articles and types of papers. Noteworthy findings from the content analysis are the frequent connection between LM’s Process Mapping and I4.0’s MES, as well as the frequent association of I4.0’s Internet of Things with LM’s OEE. The OEE-I4.0 integration is predominantly characterized by enhanced OEE and real-time data utilization, while MES-Lean integration showcases documented impacts on production efficiency, resource management, and continuous and operational system improvement. This study highlights the importance of adopting relevant Lean Manufacturing 4.0 practices for manufacturers and scholars. The importance of Lean Manufacturing 4.0 practices and the understanding of connections between OEE and I4.0, as well as MES and LM, are addressed in this study, emphasizing the imperative for businesses to adopt Lean Manufacturing 4.0.

The methodology involves the incorporation of industrial steel chips having length 75mm to 100mm in combination with varying widths of wire mesh reinforcement. Comprehensive shear tests were conducted on precisely prepared beam specimens measuring 150mm×150mm×900mm to assess shear strength, crack patterns, and failure modes. The study induces steel chips into the concrete mix at a rate of 0.9% by weight and comprises eight sets of specimens,including a control sample without any mesh reinforcement, along-with specimens reinforced with wire mesh strips ranging from 12.5mm to 87.5mm in width. Notably, the inclusion of steel chips and wire mesh enhances the shear behavior of concrete beams across all samples. As the steel chips and wire mesh acts like small-diameter bars, contributing to the enhancement of shear by improving the interlocking of concrete constituents and eff ectively distributing stresses throughout the beam’s cross-section, leading to distinctive diagonal crack patterns on the beam surfaces. The study unveils that with the increasing width of the wire mesh, there is an increase in the number of cracks while the crack widths decreases. The test outcome reveals that percentages increase of 13.66, 22.89, 31.37, 46.50, 55.00, 66.80 and 78.60 respectively, demonstrating the effective enhancement of shear strength through the utilization of wire mesh and steel chips.

The primary method used by conventional fire detection systems is sensor-based detection, which has limitations in terms of accuracy and detection time. Traditional approaches and techniques could be improved by the latest advancements in computer vision-based technologies for fire prediction and detection. Consequently, this paper aims to provide a comprehensive literature analysis of earlier research on fire detection and prediction using the computer vision techniques. The Preferred Reporting Items for Systemic Reviews and Meta-Analyses, or PRISMA 2020, are applied in this systematic review. Three databases such as the Web of Science, Scopus, and IEEE were searched for pertinent publications to include in this review for this study. The systematic review reveals that existing studies predominantly focused on fire flame rather than smoke detection. Moreover, the majority of research has centered on forest fires in the particular context of occurrence, neglecting indoor or interior environments. Video surveillance systems emerge as the primary source of hardware and datasets utilized in these investigations. Notably, convolutional neural networks (CNNs) stand out as the most frequently employed deep learning approach for classification purposes. The systematic review clarifies the state of fire detection research using computer vision techniques by combining data from several academic sources. Through a systematic approach, this study contributes a deeper understanding of the opportunity and challenges in leveraging visionbased technologies for fire detection and prediction.

Magnesium-air fuel cell (MAFC) is a hybrid system that combines the design of a fuel cell and a battery, requiring a constant replacement of anode and electrolyte to operate. MAFC application is limited for short-term high-power applications like emergency and portable power supplies because of severe corrosion problems impairing the performance of MAFC. Hence, this study focuses on performance by investigating the effect of electrolyte volume, electrodes position, and electrolyte concentration on performance of Mg–air fuel cell. Three sets of experiments were conducted starting with variation in volume of electrolyte. Then, it is applied in the cell configuration to test the MAFC performance with different electrode position. Lastly, the best electrode position is applied to the new modified MAFC together with the chosen electrolyte to investigate the effect of electrolyte concentration on MAFC performance. Finding shows that electrolyte volume not really significant to the performance while higher NaCl concentration can increase the performance of MAFC significantly. 10 wt% of NaCl produce the highest power density of 38.95 mW.cm-2 and operating voltage of 1.67 V. Unfortunately, higher corrosion rate was observed in higher NaCl concentration. Finally, adding sodium phosphate act as corrosion inhibitor manage to suppress the corrosion reaction and lowers the corrosion rate.

The utilization of the jet impingement technique is a prevalent approach in enhancing the efficiency of photovoltaic thermal (PVT) collector through the augmentation of heat transfer rate. The present work introduces a novel approach known as the reverse circular flow jet impingement (RCFJI) on a PVT collector. The performance analysis of the PVT collector was assessed through the utilization of CFD simulation. The RCFJI was installed to a jet plate which incorporates 36 holes. The holes were positioned at a spacing of 113.4 mm (x-axis) and 126 mm (y-axis). The air outlet channel of the jet plate has been configured into four different configurations: one hole (1h), three holes (3h), four holes (4h) and five holes (5h) to analyze the best outlet configuration leading to the highest energy performance. The simulation evaluation encompassed a range of solar irradiance spanning from 600 W/m2 to 900 W/m2, while the mass flow rates varied from 0.01 kg/s to 0.14 kg/f for each geometrical design. Based on the research, the configuration that records the highest efficiency was 1h. The maximum photovoltaic efficiency recorded was 11.38% at 600 W/m2 and mass fl ow rate of 0.14 kg/s. While the maximum thermal efficiency was 63.2% at solar irradiance 900 W/m2 and mass flow rate of 0.14 kg/s.

The solar-assisted heat pump drying (SAHPD) system uniquely incorporates solar-heating refrigerant through hot water from solar evacuated tubes, offering distinct advantages. This study analyzed three experimental setups: a heat pump dryer (HPD) without solar assistance, SAHPD configuration 1 (C1-SAHPD) with solar-heated refrigerant at the discharge line, and SAHPD configuration 2 (C2-SAHPD) with solar-heated refrigerant between condensers, both for performance and economic viability. The experiments maintained consistent parameters, including 5.5 kg of Pandan leaf (Pandanus amaryllifolius), an airflow rate of 0.135 kg/s, and a refrigerant operating pressure of 9.65 bar. The SAHPDs operated when the hot water temperature in the storage tank reached between 70°C and 90°C, with a daily average radiation intensity ranging from 0.670 to 1.102 kW/m² for heating the water. The study revealed average coefficients of performance (COPavg) of 5.34, 5.43, and 6.53 for HPD, C1-SAHPD, and C2-SAHPD, respectively. The specific moisture extraction rate (SMER) for HPD was 2.64, while C1-SAHPD and C2-SAHPD had SMERs of 1.88 and 2.71 at solar fractions of 0.34 and 0.45, respectively. Notably, C2-SAHPD reduced electricity consumption by 46%. The payback period for drying 11 kg of Pandan leaves per day was 4.56 months for HPD, 4.32 months for C1-SAHPD, and 3.84 months for C2-SAHPD. The study concluded that C2-SAHPD was the most efficient dryer system for Pandan leaves based on its higher efficiency, SMER, and cost recovery. Additionally, the performance optimization presented in this study contributed to developing a novel technique for classifying dryer technologies.

In many practical applications, AISI 1045 carbon steel is subjected to various external factors, one of which is vibration. This vibration can induce resonance in the material, ultimately leading to fatigue due to cyclic stress. The aim of this study is to investigate the mechanical behavior of AISI 1045 carbon steel when subjected to both static and cyclic loading conditions, and to assess how its fatigue properties change across different test frequencies, and to validate a mathematical model that predicts fatigue life through statistical analysis. To ensure accurate and standardized testing, the specimen geometry follows the ASTM E466 standard for tensile and stress-life tests, and the ASTM E290 standard for three-point bending tests. The study involves conducting a series of mechanical tests, including tensile tests, stress-life tests, and three-point bending tests, which provide critical data on the material’s fatigue life under various conditions. By analyzing the results, the researchers aim to establish a clear relationship between the applied load frequency and the material’s fatigue life. Additionally, based on this relationship, they propose a mathematical model to predict the fatigue life of AISI 1045 carbon steel across different frequencies. This model could be useful in estimating the durability and performance of components made from this steel when subjected to dynamic and fluctuating loads, helping engineers design more reliable system and predicting material performance under varying operational conditions.
