ТЕМПЕРАТУРНІ ЗАЛЕЖНОСТІ УСЕРЕДНЕНИХ ГРУПОВИХ ШВИДКОСТЕЙ АКУСТИЧНИХ ФОНОНІВ У ПЛОСКИХ НАНОПЛІВКАХ ДИЙОДИДУ СВИНЦЮ
Authors: ЛУЦЮК Юрій
Published: January 2025

Унікальні властивості квазідвовимірних структур на основі шаруватого напівпровідника – дийодиду свинцю – роблять їх привабливими для створення новітніх пристроїв наноелектроніки. На даний час розроблено низку технологій отримання квазідвовимірних структур на основі дийодиду свинцю та накопичено великий обсяг результатів експериментального дослідження їхніх властивостей. Проте, робіт, присвячених теоретичному опису явищ і процесів, що мають місце у таких структурах, досить мало. Зокрема, мало вивченим залишається питання ролі акустичних фононів у формуванні характерних властивостей названих структур. Мета даної роботи полягала в теоретичному дослідженні температурних залежностей середніх групових швидкостей акустичних фононів у наноплівках дийодиду свинцю різної товщини. Методами класичної динаміки атомів кристалічної ґратки в наближенні пружного континууму розраховані значення частот і групових швидкостей акустичних фононів у гексагональній квазідвовимірній кристалічній структурі – наноплівці дийодиду свинцю (політип 2H-PbI2). Обчислення проведені з використанням раніше вста- новлених нами аналітичних залежності законів дисперсії цих величин для кожної з мод акустичних фононів усіх можливих поляризації: зсуву (shear), згину (flexural) та розтягу (dilatational) . Подальше усереднення групових швидкостей виконане методами квантової статистики з використанням функції розподілу фононних станів за частотами у 2D-структурі та розподілу Бозе-Ейнштейна. Таким чином уперше виконано дослідження температурних залежностей середніх швидкостей фононів кожної з указаних поляризацій для різних наборів значень параметра N – кількості шарових пакетів 2H-PbI2 у нано-плівці, який визначає її товщину. Показано, що зміною температури та товщини наноплівки можна суттєво змінювати швидкість поширення в ній фононів кожної з поляризацій. Зокрема, зменшенням товщини наноплівки дийодиду свинцю можна досягти зменшення групової швидкості фононів shear-поляризації – у рази, а SA- та AS-поляризацій – в десятки разів. Температурні зміни швидкостей поширення фононів нелінійні – в області низьких температур (нижче 150, 90 і 50 K для фононів SA-, AS- та shear-поляризації, відповідно) їх значення стрімко зростають при збільшення температури, а при більш високих – практично не залежать від неї. Результати даного дослідження можуть бути використані для створення термоелектричних пристроїв на основі наноплівок 2H-PbI2 з бажаними властивостями, оскільки швидкість теплових потоків, що визначається швидкістю поширення акустичних фононів, регулюється відповідним підбором їх товщини.

This study provides a comprehensive examination of Ichneumon wasp damage on Raily Tasar silkworm cocoons in Chhattisgarh, offering critical insights into the prevalence and distribution of this parasitic infestation. These cocoons traditionally considered resistant to Ichneumon wasp infestations, but during the study, unexpected evident damage symptoms are exhibited during the First crop (Chaiti) harvests in June. The emergence of characteristic signs, including distinct holes at the peduncle base and pupal exit points, confirmed the presence of the Ichneumon wasp and its parasitic activity within the Raily cocoons. The investigation further revealed a notable range in the extent of Ichneumon wasp damage, with percentages ranging from 1.43 to 8.10 per cent across various forested locations in Bastar. District wise analysis indicated that Bastar experienced the highest damage rate (23.50%), followed by Kondagoan (20.50%) and Dhantewada (17.00%). These variations underscore the localized disparities in infestation severity, emphasizing the need for targeted interventions in areas facing higher damage rates.

Published: January 2025

The detection of Japanese encephalitis virus (JEV) in pigs, at four piggeries in the Murray region in February 2022, prompted a public health investigation (PHI) by the New South Wales Department of Health (NSW Health) to identify people at greatest risk of infection. The PHI included three components: a vaccination clinic and accompanying clinic questionnaire; a serological investigation; and a cross-sectional study for consenting Australian-born participants who completed an extended questionnaire after receiving their serological results. The goals were to vaccinate a presumably naïve population to reduce associated risk and to understand the seroprevalence among Australian-born piggery workers.
A total of 322 farm workers and/or residents attended clinics organised by NSW Health; 311 received a JEV vaccine (96.6%); and 302 (94%) completed a clinic questionnaire. Of 178 people from whom serology was collected (55.3%), a total of 165 returned Defined Epitope Blocking enzyme-linked immunosorbent assay (DEB ELISA) results; 153/165 of those returning DEB ELISA results were Australian born. The study’s cross-sectional component involved 129 participants, ten of whom were seropositive.
The overall seropositivity for 153 Australian-born participants across the identified piggeries was 6.5% (95% confidence interval [95% CI]: 3.4–12.0%), suggesting that JEV was circulating in piggeries, and plausibly more broadly, within the Murray region prior to serology collection. Male sex and working on, or visiting, a farm other than their regular workplace were both associated with JEV seropositivity (odds ratio [OR]: 5.4; 95% CI: 0.94–137.1 and OR: 37; 95% CI: 0.92–22.08 respectively).

Authors: Adam Sutisno , Sailuddin Sartika Putri
Published: January 2025

One of the challenges that language teachers face is developing the language competence of Foreign Language learners so that they can use language correctly and appropriately in a variety of social contexts. This study aims to observe whether there is an effect of pragmatic instruction in EFL classroom to learners’ grammatical and pragmatic competence. The data collected were from year 2 English students by using grammatical and pragmatic pre-tests and post-test for students to answer. Students were divided into two groups of the treatment group which receive pragmatic instructions of implied meanings and the control group which received regular teaching. Students’ answers in the tests were analysed quantitatively to obtain the mean score and further will be compared. The results show that: 1) students perform low on both aspects in both pretest and posttest (m1.1=3.63, m1.2=4.83, m2.1=4.27, and m2.2=3.47), 2) there is a moderate positive effect of pragmatic instruction on students’ grammatical competence (t(60)=-3.73, p=0.000), and 3) there’s no effect of pragmatic instruction on students’ pragmatic competence (t(65)=1.73, p=0.089). This finding indicates the role that explicit pragmatic instruction may play in boosting EFL learners’ grammatical development, along with the extensive grammar learning that learners received. It suggests the need EFL curricula revision through incorporating pragmatic features in grammatical subjects. In this way, grammar learning can be improved, and pragmatic teaching model can also be created.

Published: January 2025

The current existence of AI is unstoppable. Many parties consider AI to be a serious threat to the world of education, including universities. The use of AI by students in doing tasks often causes anxiety among lecturers. There is concern that AI reduces students’ creativity in exploring their own ideas in making essays or designing learning materials (worksheets). One of the courses that require students to explore their creativity is ESP Material Development. In this course, students are required to learn to develop teaching materials in the form of worksheets in accordance with the needs analysis results identified in the ESP Program Design course. This research is designed to find out students' tendencies in using AI for developing ESP worksheet, while also finding out whether they think that AI chatbot is really useful for them so that they can yield an ESP worksheet whose activities are in accordance with the learning objectives and having an attractive and professional appearance in the same time. The methods used were questionnaires for and FGD with 40 ESP Material Development class students. It was found that most students tried to use AI chatbot for getting inspiration whenever they get stuck in finding more ideas for their worksheets. Most students admitted that AI helped them in that situation. However, they did not recommend the use of AI from the very beginning of developing worksheets. They confessed that using AI would cause confusion and reduce creativity when it is used since very beginning.

This study explores the attitudes and valorization of languages among Indonesian engineering students at Cendikia Abditama University. Employing a qualitative research design, the study gathered data from 70 students through questionnaires, supplemented by in-depth interviews with 10 participants to gain richer perspectives. A descriptive analytical approach was used to interpret the findings, revealing a predominantly positive attitude toward English, Indonesian, and heritage languages. This demonstrates a nuanced balance between cultural pride, national identity, and the global opportunities associated with these languages. The research highlights that while many students value all three languages equally, others exhibit a preference for one language over the others, depending on their immediate academic, professional, or personal aspirations. These variations reflect the dynamic interplay between cultural heritage and global competitiveness in shaping language attitudes. The findings underline the critical role of educational policies in supporting linguistic diversity and fostering inclusive learning environments. By integrating students’ linguistic backgrounds into educational curricula, institutions can enhance learning experiences and promote multilingual competence. Such approaches can help prepare students for the challenges of a globalized world while maintaining their cultural roots, thereby contributing to more comprehensive and meaningful educational practices. This study emphasizes the significance of aligning language education with students' diverse needs and aspirations.

Authors: Mardhatillah Siti Masyitha , Agustina Agustina
Published: January 2025

Recently, the Indonesian public has been stirred by various comments regarding several videos showing religious activities at Al-Zaytun Islamic Boarding School, which were considered deviating from religious teachings. These public comments sparked a response from the school's leader (PG), which was found to contain hate speech that was even more shocking. Therefore, this study aims to "uncover the types of hate speech found in PG's statements and critically analyze them through linguistic units as the means of delivery." This research employs a qualitative-quantitative approach and a descriptive-exploratory method, with the data object being PG's clarification statements during a Talk Show event.Based on the data analysis, the following results were obtained: First, six types of hate speech were identified in PG's statements, namely: (1) provocation (27%), (2) defamation (20%), (3) incitement (20%), (4) blasphemy (17%), (5) insult (15%), and (6) spreading fake news (1%). Second, the hate speech was conveyed through four types of linguistic units: (1) sentences (77%), (2) phrases (16%), (3) clauses (4%), and (4) words (3%). Based on these findings, it can be concluded that the dominant form of hate speech expressed by PG is through the use of sentences. This type of speech is primarily aimed at defending and justifying his belief that the religious policies and activities at the Islamic Boarding School he leads do not violate religious teachings and do not harm other parties or institutions.
ChatGPT and Google Gemini in EFL Education: A Qualitative Exploration of Pedagogical Efficacy among Indonesian Sophomores
Authors: Baskara FX. Risang
Published: January 2025

As generative language models like ChatGPT and Google Gemini gain prominence in education, their efficacy in specific contexts, such as Indonesian English as a Foreign Language (EFL) instruction, still needs to be explored. This study investigates the pedagogical affordances and constraints of these models as perceived by Indonesian EFL sophomores, aiming to understand their contribution to active learning in language acquisition. Using a qualitative approach, we conducted open-ended questionnaires with 40 sophomore students from an Indonesian university's English department. Thematic content analysis was employed to analyse the data. Findings reveal that ChatGPT offers authentic conversational simulations and versatile content-based instruction, while Google Gemini's strength lies in its multilingual capabilities. However, limitations such as linguistic complexity and rigid conversational structures were also identified. The study suggests these models can enhance active learning experiences, particularly in conversational practice and interdisciplinary content exploration, though their efficacy depends on factors like learner proficiency and internet access. We conclude that integrating these models into EFL instruction requires careful consideration of their affordances and limitations. This study contributes culturally-specific insights to AI in education research, with implications for curriculum designers, educators, and policymakers in developing countries, emphasising the need for adaptive and inclusive approaches in AI-enhanced EFL education.
In pursuit of complexity: Multifaceted approaches to cardiac tissue engineering
Authors:   , Chirico Nino
Published: January 2025

Cardiovascular diseases (CVDs) are the leading cause of death worldwide, with around 17.9 million deaths annually. In Europe, heart disease causes 3.6 million deaths each year, contributing to a significant healthcare burden. The main cause of heart failure is myocardial infarction (MI), where blockages in coronary vessels lead to the death of cardiac cells and loss of muscle function. Current treatments are mostly palliative, with heart transplantation being the only cure, but it is limited by donor organ availability.

This thesis aims to address heart failure challenges by developing improved in vitro models and engineered tissues for therapy discovery and reparative interventions. Traditional models, such as 2D cultures, fail to replicate native cardiac physiology. Induced pluripotent stem cells (iPSCs) have revolutionized cardiac research by producing cardiomyocytes (iPSC-CMs), but these cells are immature, limiting their clinical applicability. To enhance disease modeling, Chapter 2 presents a protocol to induce rapid maturation of iPSC-CMs, improving their function.

Chapter 3 discusses high-throughput solutions for cardiac spheroids, while Chapter 4 introduces the VoluHeart, a bi-chambered heart model created with volumetric bioprinting that replicates post-injury cardiac remodeling. Chapter 5 highlights the importance of integrating circadian rhythms into cardiac models to improve physiological relevance. Advances in stem cell technology and bioengineering have enabled the creation of models that better simulate human physiology and pathology.

Chapter 6 stresses the importance of replicating the 3D structure of cardiac tissue, while Chapter 7 introduces pre-vascularized engineered heart tissue using a melt-electrowritten (MEW) mesh and hydrogels, offering improved functional survival. Annex 2 demonstrates the development of a 1-centimeter-thick cardiac tissue construct with precise tissue alignment, promoting natural-like contraction and enhancing potential for clinical applications.

The thesis also addresses the need for long-term storage of implantable cardiac tissues, reviewing preservation methods in Chapters 8 and 9. These include hypothermic and cryogenic storage techniques, which are essential for transporting cardiac constructs between research facilities and enabling off-the-shelf tissue availability for reparative interventions.

Overall, the thesis proposes a comprehensive strategy combining stem cell technology and advanced bioengineering to develop more accurate cardiac models and novel therapies for heart failure, ultimately advancing the potential for functional cardiac tissue repair.

The Search for the Best Concrete Surface Texture Relative to Noise and Skid Resistance in Québec

Concrete pavements under the ministère des Transports du Québec (MTQ) are located on the highest trafficked roads in the province, often in urban areas. In the late 1990s, the MTQ noted a skid resistance problem for most of the concrete pavements rebuilt since 1994. The texture specified at the time for the new pavements was the result of dragging an Astroturf mat on the surface of the fresh concrete. This produced a low noise pavement, but skid resistance measurements were disappointing. Since 2000, the MTQ has specified the transverse tining on fresh concrete; this technique is known to provide better skid resistance. However, it is sometimes noisier and complaints were recorded in some areas. It was also found that skid resistance issues still occurred because of the limestone coarse aggregate used in almost all concrete pavements since 1994. It has been banned since 2003. Since 2004, to counter the noise effect, the longitudinal tining technique has been increasingly used by MTQ project engineers. Various other techniques were tested on new slabs such as exposed aggregate, shot-blasting and grinding. All our experimental sections were subject to tire-pavement noise measurement by our custom-made equipment.
Concrete Pavement Texture and Optimizing Functional Performance

Concrete pavement texture is defined by the irregularities on a concrete pavement surface that deviate from an ideal, perfectly flat surface. Texture influences many aspects of road safety and comfort, including friction, smoothness, splash & spray, rolling resistance, and numerous others. The focus of this paper is on techniques to measure and analyze texture, particularly that which influences tire-pavement noise and friction. Standards for characterizing texture geometrically are described, and techniques that describe texture in terms of its influence on functional performance are explored.

This paper presents the first findings and analysis of data collected in a monitoring program of a newly constructed continuous reinforced concrete highway pavement initiated in 1997. This monitoring program was set up as it was felt that pertinent data were not available to make an objective comparison in the process of deciding between an asphalt and a continuos reinforced concrete pavement structure. Over a ten-year period a wide range of data will be collected such as construction data, including laboratory results, traffic, temperature (air and pavement), structural condition, detailed visual inspections, surface friction, roughness, noise level, joint movements and other relevant information. All data and reports will be stored in a database to facilitate easy access and quarrying. The data collected over the first three years and the analysis performed have resulted in a detailed insight into the as-built parameters, development of stresses based on the change in temperature gradients and the traffic load spectrum. At this stage of the monitoring program conclusions can already be drawn based on the information gathered to date as processed in a study performed at Delft University of Technology.
MECHANISTIC ANALYSIS OF FACTORS LEADING TO PUNCHOUT DEVELOPMENT FOR IMPROVED CRCP DESIGN PROCEDURES

Published: January 2025

The design of continuously reinforced concrete pavements (CRCP) has traditionally focused on the design of the steel reinforcement relative to the development of the crack pattern but with little emphasis on how characteristics of the crack pattern influence pavement performance. Recent developments associated with the mechanistic-based 2002 Design Guide (under development in NCHRP Project 1-37A) have further reinforced the importance of mechanistic relationships between the design parameters and pavement response to enable pavement performance predictions. To enhance the predictability of CRCP performance, a mechanistically sound relationship that relates the design parameters of crack spacing distribution, crack width, load transfer efficiency of the transverse cracks, and support conditions to pavement structural response needs to be incorporated in the design procedure. The results of this effort would benefit the development of a comprehensive mechanistic-based design procedure for CRCP.

Chitosan effects on soil properties were analysed both under laboratory conditions by incubation with constant humidity and temperature and under field conditions in two persimmon field plots with conventional and ecological management. Chitosan was applied in solution or as coacervates. Application of chitosan reduced soil pH, conductivity (CE), and cation exchange capacity (CEC) in pots when applied at field capacity. Chitosan did not affect field soil respiration, which is greatly dependent of soil moisture and temperature. Metabarcoding showed that chitosan significantly modifies the fungal genera composition of ecologically managed field soil. On the contrary, chitosan caused no significant differences in bacterial taxa composition of soil under field conditions. Chitosan coacervates increased naturally occurring nematophagous fungus Purpureocillium (ca. 50-fold) in soil with respect to chitosan solution-treated soil and untreated controls. In addition, chitosan reduced the inoculum of plant pathogenic fungi Alternaria and Fusarium (20% and 50%, respectively) in field soil. Soil microbial network analysis for ITS2+V1–V2 regions revealed that the nematophagous fungus Pochonia promoted network clustering into modules. Furthermore, network analysis for ITS2+V3–V4 regions showed that the nematode trapping-fungus Orbilia and bacteria belonging to Acidimicrobiales and Cytophagales significantly contributed to network clustering in field soil. Our results show that chitosan coacervates increased soil nematophagous microbiota and that both nematode egg parasites and trapping fungi help to structure soil microbiota.
