Sejak 2019 di Wuhan, China mewabah virus corona virus desease (Covid-19). Hal ini tidak hanya menimbulkan masalah kesehatan, tetapi masalah lingkungan dengan munculnya timbulan limbah masker sekali pakai. Masker medis maupun nonmedis umumnya berbahan baku nonwoven spunbond atau meltblown spunbond dengan campuran polimer berupa poliester atau polipropilen. Tujuan dari penelitian ini adalah suatu rancang bangun material komposit alternatif dari limbah masker nonmedis berbahan baku polipropilen dalam mengurangi limbah masker nonmedis di lingkungan masyarakat. Pada penelitian ini pembuatan komposit menggunakan limbah masker sebagai bahan pengisi (filler) dan resin poliester sebagai perekat (matrix). Komposit dibuat menjadi dua jenis sampel yaitu komposit dengan filler panjang dan pendek untuk mengetahui pengaruh panjang pengisi filler komposit terhadap kekuatan tarik yang dimiliki komposit. Prosedur pembuatan komposit menggunakan metode hand lay up dengan menuangkan dan perataan secara bergantian filler dan matrix yang dituangkan ke dalam wadah. Sampel komposit yang telah dibuat dipotong menjadi 10 spesimen sesuai dengan standar ASTM D638-14 untuk dilakukan pengujian kekuatan tarik dan pengukuran ketebalan komposit. Bedasarkan hasil pengujian didapatkan bahwa nilai kekuatan tarik komposit dengan filler panjang lebih besar dibandingkan komposit dengan filler pendek. Kesimpulan dari penelitian ini adalah limbah masker dapat dijadikan alternatif bahan komposit.

The Effect of Using Zeolite and Agave Sisalana Fiber on Compressive Strength Using the Self Compacting Concrete (SCC) Method
Authors: Zulkarnain Fahrizal , Batubara Amar Azhari 
Published: November 2024

Self Compacting Concrete (SCC) is concrete innovation which does not require vibrations during installation and compaction. SCC concrete can flow freely with its weight and is capable of filling a mold well, ensuring perfect compaction without vibration. In 1988, in order to eliminate or reduce the need for vibration to achieve density and thereby reduce the labor required for concrete placement, SCC was developed in Japan. In this research, the production of SCC was investigated by replacing the fine aggregate in the SCC mixture by 3%, 7% and 11% of zeolite material and by adding 0.005% of agave sisalana fiber of cement weight. The 15/30 cm concrete cylinders were used in 16 samples for compressive strength. It is shown that the values of flowability, filling capacity, and permeability decrease with increasing use of zeolite content based on the results of the research conducted. The results of the compressive strength test show that the variation of 7% zeolite + 0.005% sisalana fiber has the highest value of compressive strength at FAS 0.43, with an average of 38.46 MPa, and the highest value of compressive strength at FAS 0.45, with an average of 37.07 MPa.
Making Human Learning Visible in a World of Invisible Generative AI
Authors: Salter Marie , Bonfield Christopher 
Published: November 2024

The growth of Generative Artificial Intelligence (GenAI) in Higher Education (HE) challenges us to think differently and creatively about learning and assessment in order to prepare graduates for their futures (Dawson, 2023) This presentation will argue that the very strength of GenAI is also its Achilles’ heel. Anyone can access, garner and generate data rapidly, but human beings have never had a greater need for scrutiny and evaluation of this output. Our graduates will need to have a transparent understanding of how they are learning in terms of the critical choices they make, the information or knowledge they engage with, and where machine learning ends and theirs begins (Okolie et al, 2022). The future of assessment in HE must go beyond simply measuring knowledge acquisition and instead focus on capturing and evidencing students’ capacity for critical thinking.
We will highlight some preliminary findings and early impacts of work underway at the University of Bath (UK) and University of Stellenbosch (South Africa), who are working collaboratively to ensure students develop holistically, excel in critical thinking, and gain the confidence and skills to use GenAI effectively to advance their ideas and learning (Osborne, 2024).
This will be structured in three parts:
Part one (Reviewing): We will outline work during academic year 23/24 by academic staff to review all their assessments against a three-fold categorisation model of permitted GenAI usage. From September 2024, all assessments clearly signal to students the extent to which GenAI is permitted in each assignment.
Part two (Guidance): We will showcase resources that support staff to rethink assessment design that embeds GenAI in ways that are authentic, valid and robust (Upsher et al, 2024). We will also present resources that support students to consider how they might use GenAI ethically, and to develop their AI literacy skills and critical thinking.
Part three (Examples): We will present initial findings from an internal project that is engaging with national and international employers, in-house world-leading AI researchers and our own students that highlight creative approaches to harnessing GenAI as a tool to reinforce and support (rather than replace) human learning.
We conclude by suggesting that HE has always promoted critical thinking and the rigorous investigation and examination of the production of knowledge. We need graduates who can critically engage with their learning, and assessments that capture and evidence this. The only way to do this effectively is to put people at the start, middle and end of our assessment journey.

Published: November 2024

Abstract
Copper (Cu) is considered one of the major heavy metal pollutants in agriculture, leading to reductions in crop yield. To reveal the molecular mechanisms of resistance to copper stress in maize (Zea mays L.) seedlings, transcriptome analysis was conducted on the hybrid variety Zhengdan 958 exposed to 0 (control), 5, and 10 mM Cu stress using RNA-seq. In total, 619, 2,685, and 1,790 differentially expressed genes (DEGs) were identified compared to 5 mM versus 0 mM Cu, 10 mM versus 0 mM Cu, and 10 mM versus 5 mM Cu, respectively. Functional categorization of DEGs according to Gene Ontology revealed that heme binding, defense response, and multiorganism processes were significantly enriched under copper stress. Additionally, Kyoto Encyclopedia of Genes and Genomes enrichment analysis suggested that the copper stress response is mediated by pathways involving phenylpropanoid biosynthesis, flavonoid biosynthesis, and glutathione metabolism, among others. The transcriptome data demonstrated that metabolite biosynthesis and glutathione metabolism play key roles in the response of maize seedlings to copper stress, and these findings provide valuable information for enhancing copper resistance in maize.

Abstract
The risks and challenges of the NEOM project on water bodies can be somehow resolved by using Cystoseria sp., a brown-green macroalga, and natural renewable resource species, which are appealing due to their sustainability, cost-effectiveness, and eco-friendliness. Lipid was extracted from Cystoseria sp. collected from Sharma beach, Neom, Tabuk, Kingdom of Saudi Arabia. It was treated with different solvents, petroleum ether, methanol, and petroleum ether:methanol (1:1), to obtain biofuel. Petroleum ether and methanol were the most significant solvents for extractions of six different hydrocarbon compounds, followed by methanol. Tetrahydradecane 5-methyl 60.03% in petroleum ether, 59.51% in methanol, and 51.39% in petroleum ether:methanol is obtained. Removal of 10 mg·L−1 methylene blue (MB) by alga using 0.2 g·L−1 of Cystoseria sp. and its residues after methanol extract was achieved in 120 min. Zeta potential analysis of alga confirms that different negative charges on adsorbent surfaces undergo conformational change with different solvents and adsorb the positively charged MB via electrostatic interaction force. The production of bioethanol efficiency percentage from Cystoseria sp. ranges from 5% to 68.97%. Hence, Cystoseria sp. can be a renewable resource to yield biodiesel and bioethanol and eliminate MB from wastewater, maintaining environmental sustenance and economic development.
Thermochemical energy storage with the solid-gas reaction of SrCO3 improved with CaCO3
Authors: Santamaria Padilla Adriana , Romero-Paredes Rubio Hernando , Carrera Peralta Rosalba , Hernández Zamudio Rubén Alfredo 
Published: November 2024

Abstract
In the context of thermochemical energy storage (TCES) for concentrating solar power (CSP) applications, metal carbonates’ reversible calcination and carbonation are gaining prominence, particularly in the SrCO3/SrO system. This system is notable for its high theoretical energy density of 10.61 GJ/m³ and operational temperatures up to 1,200 °C. However, like the CaCO3/CaO system, SrO experiences a significant drop in reactivity during cycling due to sintering and agglomeration of particles. In this work is proposed that the conversion effective will be improved by mixing the strontium carbonate with calcium carbonate. The best mix found was 80/20 SrCO3/CaCO3 with the operating parameters of calcination-carbonation temperatures of 1,200 °C and 900 °C, respectively. This reaction has a notably better stable conversion rate than pure strontium carbonate. The study was carried out using thermogravimetry analysis. The mixture was subjected to 9 cycles, and for the ninth cycle, there was an effective conversion of 33.14 %, which, compared to pure SrCO3, was 2.33 %; that was improved noticeably during the carbonation process. There was an increase in the percentage effective conversion of 30.81 %. Volumetric energy density was reduced from 6.93 to 2.81 GJ/m3 in the first and after nine cycles. The XRD analysis of the unprocessed mixture after 4 and 9 cycles showed no formation of new or secondary compounds, only the expected compounds: SrO, SrCO3, CaO, and CaCO3. This important change is explained during the carbonation looping because the CaO remains encapsulated in the SrCO3 and does not react completely at 900 °C. As a hypothesis, this encapsulation delays the sintering of the SrCO3. Using a T
carb = 850 °C promotes the carbonation of CaO. By promoting CaO to react, the CaO encapsulated is released rapidly, and the material was sintering faster than the T
carb = 900 °C. Comparing the seventh cycle at a T
carb = 900 and 850 °C, it is observed that the effective conversion decreases from 0.4431 to 0.4202 and, in the same proportion, the volumetric energy density.

Abstract
The insectivorous bat genus Cynomops belongs to the Neotropical fraction of the family Molossidae, which includes Free-tailed Bats or Mastiff Bats. Currently, nine species are recognized within Cynomops. In this study, we present the first records of Cynomops kuizha for the Colombian Caribbean Region. The two female specimens were recovered in the campus of the Puerta Roja of the University of Sucre, Sucre and represent a significant extension in the geographical and ecological distribution of the species. With these new records, the known distribution of this species is extended approximately 520 km northeast of the nearest previous record in the department of Valle del Cauca, Colombia. Identification of both specimens was carried out through morphological comparisons and analysis of the mitochondrial gene cytochrome-b (Cyt-b). Molecular analyses revealed that the Cyt-b sequences from the Sucre specimens are >99 % similar to those documented for C. kuizha in southwestern Colombia. With these new records, the known distribution of this species is extended approximately 520 km northeast of the nearest previous record in the department of Valle del Cauca, Colombia. Additionally, we discuss some morphological peculiarities observed in our Sucre specimens and their relationship with closely related species present in the area: Cynomops abrasus, Cynomops greenhalli, and Cynomops mastivus.

Abstract
This article presents the application of the Faedo–Galerkin compactness method to establish the local well-posedness of the Newell–Whitehead–Segel equation. By analyzing a finite-dimensional approximate problem, the existence and uniqueness of a local solution were demonstrated. A priori estimates were derived, enabling the transition to the limit and the recovery of the original problem’s local solution. The study further proves the uniqueness and continuous dependence of the solution on initial data. Additionally, under certain conditions, it is shown that the energy norm of the solution decays exponentially over time, and the

Effect of temperature and nanoparticle size on the interfacial layer thickness of TiO2–water nanofluids using molecular dynamics
Authors: Huang Xiaoyan , Zhang Xiaohui , Qing Shan 
Published: November 2024

Abstract
In the design and optimization of nanofluids, it is crucial to investigate and characterize the thermal conductivity enhancement mechanisms and their influencing factors. Although the effect of the “liquid film” on the thermal conductivity of the solid–liquid interface in nanofluids has been extensively studied, most of the research in this area has examined metal–water nanofluids or Ar-based nanofluids. In this work, non-equilibrium molecular dynamics is utilized to explore the mechanism of thermal conductivity enhancement in TiO2–water nanofluids. It is noted that a distinct interfacial layer is formed within 5 Å from the nanoparticle surface. As the nanoparticle size increases, the number density also increases, resulting in a corresponding increase in the thermal conductivity. Moreover, adding 1% TiO2 nanoparticles to water leads to an increase in thermal conductivity of 1.5–3%. Notably, the interfacial layer thickness remains relatively constant with the change in temperature. The Materials Studio analysis results indicated that the water molecule will have stable chemisorption on the titanium dioxide surface with an adsorption energy of approximately −0.96 eV. The findings of this study offer new insights and useful information to support the selection of nanomaterials for the preparation of convective systems.

This review examines recent advancements in surface treatment technologies for aluminum alloys used in sports equipment. We discuss conventional methods like chemical conversion coatings and anodizing, as well as emerging techniques such as plasma electrolytic oxidation, physical vapor deposition, and laser surface modification. The replacement of toxic hexavalent chromium with eco-friendly alternatives is highlighted as a key development. We also explore the potential of smart, self-healing coatings to extend equipment lifespan. Our analysis reveals that while significant progress has been made in enhancing corrosion resistance and mechanical properties, challenges remain in scaling up advanced treatments for industrial implementation. The review concludes that continued innovation in surface treatments will be crucial for improving the performance, safety, and sustainability of aluminum alloys in sports applications, ultimately benefiting athletes and manufacturers alike.
Marie Pujmanovás Novelle Die Patientin von Doktor Hegel (1931) als Beitrag zur Geschlechterdebatte der Zwischenkriegszeit
Authors: Marková Jana 
Published: November 2024

Summary
In the democratic society of interwar Czechoslovakia, there was a lively discussion about women’s emancipation and the accompanying changes in the gender order. The modernist romance Pacientka dra Hegla [Doctor Hegel’s patient] (1931) by the Czech journalist and writer Marie Pujmanová (1893‒1958) occupies a liberal position in the debate. In the story of a young woman who gives up her plans to marry in favour of a relationship outside wedlock, issues such as female sexual liberation, abortion and free motherhood are topicalised. The article highlights the connections between the romance and gender discourses of the time and examines the ideological stance of the text. Special attention is paid to the stereotyping of the four main characters, who all represent certain concepts of personal identity that were very popular in the 1920 s.
On the patterning of sound imitation by onomatopoeia in Slovak
Authors: Körtvélyessy Lívia 
Published: November 2024

Summary
This paper presents an experiment with onomatopoeia formation. Fifty-one Slovak participants were asked to imitate ten sound events of various frequencies by writing down onomatopoeic words using the letters of the Slovak alphabet. The purpose of the experiment was to examine the role of image iconicity in producing new onomatopoeias. Image iconicity is expected to be manifested in the participants’ agreement on the form of the proposed onomatopoeias and, therefore, in the possibility of establishing onomatopoeic patterns. The pattern structure was determined by the realization of five characteristics: initial position, final position, transition, lengthening, and repetition. In addition, the established patterns make it possible to examine the role of sound-symbolism, particularly phonesthemes in the formation of onomatopoeias.
