Authors: Pozo Zamora Glenda Marisol , Guachamín-Paladines Gino
Published: December 2024

Durante el décimo Conteo Navideño de Aves en Quito, Ecuador, registramos un individuo del Pinchaflor de Garganta Negra Diglossa brunneiventris, el 17 de diciembre de 2023, en la ruta del parque Itchimbía. Este es el primer registro de esta especie en Ecuador, situado c. 670 km al sur de la localidad más cercana en Colombia y 680 km al norte de la localidad más al norte de Perú. La presencia de D. brunneiventris en Ecuador podría explicarse por diversos factores: 1) que haya sido un individuo errante, 2) que forme parte de una población remanente pasada por alto, o 3) que haya sido un individuo de Pinchaflor Negro D. humeralis que exprese genes ancestrales que deriven en un fenotipo similar a D. brunneiventris. Se necesitan estudios adicionales para dilucidar el origen de esta especie en Ecuador. Este registro resalta la importancia de la ciencia ciudadana para el avance del conocimiento sobre las aves en el país.
“A Cropped Silhouette, Neither Mammal Nor Avian”: Liminality and Becoming in Sarah Hall’s “M”
Authors: Torres Zúñiga Laura
Published: December 2024

Although the English writer Sarah Hall is mostly known for her novels about the Cumbrian borderlands between England and Scotland, from Haweswater (2003) to The Wolf Border (2016), this paper employs a wider understanding of borders and boundaries not just as spatial issues, but as constructs related to embodied and identitarian processes in which borderlines are erected, breached, or destroyed. The story “M,” from Hall’s last short story collection, Sudden Traveller (2019), will be taken as a case in point to illustrate how characteristics of Hall’s fiction, such as the representation of an abjected force at the core of human behavior and of the multiplicity of female and bodily experience, are reflected by the articulation of liminal states and the blurring or breaching of different borders: geographical, corporeal and symbolic. “M” joins thus Hall’s previous stories “Bees” and “Mrs. Fox” as the final episode in a trilogy that problematizes the construction of female subjectivity and the crossing of animal-human boundaries.

Эффект добавок паров фосфорорганических соединений с различной химической структурой в пламени метановоздушной смеси
Authors: Шмаков А.Г. , Большова Т.А.
Published: December 2024

Механизм ингибирующего действия антипиренов в различных пламенах представляет интерес с точки зрения разработки эффективных методов снижения горючести полимеров. В настоящее время существует большое количество антипиренов, среди которых одними из перспективных считаются фосфорсодержащие соединения. С помощью метода зондовой молекулярно-пучковой масс-спектрометрии изучено влияние трех различных фосфорорганических соединений (ФОС) – триметилфосфата (ТМФ), диметилметилфосфоната (ДММФ), диметилфосфорамидата (ДМФА) на химическую структуру богатого (φ=1,2) предварительно перемешанного пламени СH4/O2/N2. Методами численного моделирования проведены расчеты профилей концентрации стабильных веществ, а также лабильных соединений – атомов Н и радикалов ОН в пламенах с добавками ТМФ и ДММФ. Экспериментально установлено, что зона превращения ДМФА расположена в более низкотемпературной зоне пламени, чем зоны превращения ТМФ и ДММФ. Показано, что эффект добавок трех различных ФОС в концентрации 0,02% в смеси СH4/O2/N2 на снижение максимальных концентраций атомов Н и радикалов ОН в зоне горения практически одинаков, что подтверждает ранее полученные выводы об определяющем влиянии фосфора в молекулах исследованных ингибиторов на их эффективность. Для дальнейшего анализа эффекта синергизма P-N в антипиренах из класса фосфорамидатов, простейшим представителем которых является ДМФА, необходимо исследовать кинетику химических реакций превращения этих соединений в пламени с участием атомов и радикалов.

Published: December 2024

Background: The objective of this study was to assess the effect of adding a very low dose of naloxone to a remifentanil infusion on postoperative pain in patients undergoing hip replacement surgery in the lateral position.
Methods: This randomized clinical trial involved 80 patients who underwent hip replacement surgery under general anesthesia and were randomly assigned into two groups through block randomization: group 1 received remifentanil at a dose of 0.3 μg/kg/minute, while group 2 received remifentanil at a dose of 0.3 μg/kg/minute with a very low dose of naloxone administered at 0.05 μg/kg/hour following injection. Postoperative pain [measured using the visual analog scale (VAS)], drowsiness caused by narcotics and analgesics in recovery, and the duration of getting out of bed were all monitored and recorded in the ward.
Results: The median [interquartile range (IQR)] of time to administration of the first sedative drug was 0 (0, 4) hours in the control group and 4 (0, 4) hours in the intervention group. The difference between the groups was statistically significant (P < 0.0001). The frequency of pain after surgery at 0, 4, and 8 hours was significantly different between the control and intervention groups (P = 0.003, P < 0.0001, and P = 0.021, respectively).
Conclusion: Based on the results, we recommend using a very low dose of naloxone along with remifentanil infusion in patients undergoing complete hip replacement surgery to reduce their pain and the need for painkillers

Published: December 2024

Low back pain (LBP) is a significant issue in both clinical and public health settings, resulting in high healthcare and social costs. While knee joint pain is more prevalent than hip joint pain, standing posture is influenced not only by spinal alignment but also by hip and knee joint alignment. The knee and spine are interconnected anatomically, and degenerative changes in one area could often cause discomfort in the entire axis, leading to what is known as "knee-spine syndrome". LBP is a common condition associated with knee pain and can significantly affect the results of total knee arthroplasty (TKA). Surgeons need to consider knee-spine syndrome before any surgical intervention in patients with knee or back pain and explain it to the patients before the surgery.

Cultural Shifts and Policy: How Government Actions Shape Social Behavior
Authors: Nguyen Minh Trang , Pham Nhat Minh
Published: December 2024

Shaping social behavior through public policy is a basic yet complex process, necessitating a delicate balance between government intervention, societal norms, and individual rights. Policies are created to address a wide array of social issues, such as public health and safety, economic inequality, and environmental sustainability, in an attempt to influence societal behavior for the greater good. However, most of those policies are usually opposed by resistance to change, unintended consequences, and difficulties in enforcement. This paper examines some of the main challenges to the use of policy in designing social behavior: cultural resistance, policy misalignment with social realities, ethical concerns, and political opposition. In addition, it considers the need to consider long-term impacts on society, ensure resource allocation, and adapt policies to evolving needs. This paper reviews challenges in depth and consequently underlines the complexity of using policy to achieve behavior change; it underscores the need for thoughtful design, public engagement, and ongoing adaptation in the quest for successful outcomes from social policy.

Published: December 2024

The generation, use, and analysis of educational data comes with many promises and opportunities, especially where digital materials allow usage of learning analytics (LA) as a tool in data-based decision-making (DBDM). However, there are questions about the interplay between teachers, students, context, and technology. Therefore, this paper presents an exploratory systematic scoping review to investigate findings regarding LA usage in digital materials, teaching, and learning in K–12 mathematics education. In all, 3,654 records were identified, of which 19 studies met all the inclusion criteria. Results show that LA research in mathematics education is an emerging field where applications of LA are used in many contexts across many curricula content and standards of K–12 mathematics education, supporting a wide variety of teacher data use. Teaching with DBDM is mainly focused on supervision and guidance and LA usage had a generally positive effect on student learning with high-performing students benefiting most. We highlight a need for further research to develop knowledge of LA usage in classroom practice that considers both teacher and student perspectives in relation to design and affordances of digital learning systems. Finally, we propose a new class of LA, which we define as guiding analytics for learners, which harnesses the potential of LA for promoting achievement and independent learning.
The Academic Curriculum in Higher Education. Transformative Competencies' Relevance for the Labour Market
Authors: Rogoz Nicoleta
Published: December 2024

The paper presents a theoretical analysis of the academic curriculum's relevance for the labour market and life, especially about the recognition of learning outcomes. The purpose of this approach is to discover if there is strong consent and a common interest both at the national and international levels related to the relevance of transformative competencies developed through the academic curriculum. Concerns about the key competencies have led to reflection on the importance of being aware of knowledge created by Higher Education (HE) institutions. The research questions related to the theoretical approach are as follows: What are the national and international trends regarding the academic curricula in higher education? What are the transformative competencies and what do they entail? What are the ways in which transformative competencies can be included in the national university curriculum? The results of our theoretical approach underline that the set of competences developed in HE institutions must constantly transform into learning outcomes by the trends and needs of the labour market. This type of academic curriculum development anticipates the future dynamics of a society. We conclude that the mission of the HE institutions has to be strongly related to the specifics of globalized economies. Also, it is to develop an academic curriculum orienting itself towards innovation and a competency-based approach. This holistic approach provides policymakers, researchers, administrators and teachers a theoretical framework for practical interventions in HE institutions.

Background: The study aimed to evaluate the effect of incorporating Punica granatum (pomegranate) hydroethanolic extract as a functional ingredient in yogurt on the physicochemical, sensory quality and microbiological count of freshly prepared and refrigerated stored (4°C) yogurts. Methods: Pomegranate peels were dried, ground and extracted with 70% ethanol, then concentrated using a rotary evaporator and finally lyophilized to obtain pomegranate peel powder (PPP). Yogurts were prepared using pasteurized semi-skimmed cow’s milk, with phenolic extracts of pomegranate peels added at 10.0 mg, 20.0 mg and 30.0 mg per 100 mL of milk; a control product was simultaneously prepared without such pomegranate peel extract. The physicochemical analysis included pH, acidity, syneresis and viscosity measurements. Microbiological analysis was performed to determine the viability of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus. Sensory scoring of the yogurt was carried out by 25 panelists using a 5-point scale. Result: Initial pH values of freshly prepared yogurt ranged between 4.48 and 4.64, decreasing to pH values of 4.3 and 4.15 at 21st day of refrigerated (4°C) storage. The titratable acidity of yogurt increased from initial value of 75°D for freshly prepared control product to 99°D as noted on 21st day of storage. Syneresis at the 21st of storage were 35.98%, 37.88%, 39.34%, 39.22% for yogurt samples control, experimental yogurt containing PPE of 10.0 mg, 20.0 mg and 30.0 mg respectively. The viscosity of yogurt utilizing 10.0 mg PPE peaked to value of 769.63 cP on 21st day of storage. Streptococcus thermophilus count peaked to 8.39 log CFU/g for experimental sample containing 10.0 mg of PPE as noted on 7th day of storage. Yogurt samples containing 20.0 mg and 30.0 mg of PPE received the superior overall acceptability scores over others. The extract improved yogurt’s physicochemical and sensory properties, enhancing its nutritional value and consumer acceptance.

Authors: Cebesoy Ümran Betül , Seyhan Özdemir Banuçiçek
Published: December 2024

Socioscientific (SSI)-based instruction has gained popularity in science education research as the number of controversial topics has increased daily. This study has two objectives: first, it aims to explore the quality of arguments made by pre-service science teachers (PSTs) through various SSI contexts. Second, it explores whether the context influences participants’ argument quality. For these purposes, a case study was designed with 13 senior (fourth grade) PSTs enrolling in a state university in Türkiye. Data were collected through participants’ reports. The results revealed that participants mostly articulated arguments along with supporting evidence (including backing, warrant, or grounds) without considering different perspectives (i.e., counter-arguments) and refuting evidence (i.e., rebuttal) in various SSI contexts. In terms of the SSI context, genetically modified organisms and artificial meat consumption contexts were the ones where participants were able to generate more arguments compared to other SSI contexts. Recommendations for teacher education programs in terms of enhancing the quality of arguments and the role of various SSI contexts in improving participants’ argumentation processes were provided.

The title compound 3-(2,4,6-timethyl-phenylamino)-but-2-enoate was obtained by condensation reaction of ethyl acetoacetate and 2,4,6-trimethyl-phenylamine. X-ray structural analysis identified the structure of the synthetized β-enaminoester, NMR spectroscopy complemented it, and the structure stabilized by intramolecular interactions. The intermolecular contacts were further analysed by the mapping of contacts descriptors dnorm, de, di, the shape-by-Shape index and surface property by electrostatic potential mapped on the Hirshfeld surface (HS). Data from density functional theory (DFT) was compared to experimental results for this process. Global reactivity factors such electronegativity, chemical hardness, potential, and softness were calculated using DFT. The effects of the molecular environment were accessed by analysing the electrostatic potentials surface mapped over the HS and the 3D-topology of energy frameworks. As a potential bioactive molecule, the physicochemical and ADME-Tox predictions were performed suggesting that compound 3 could be considered as promising drug candidate.

Authors: Kononov Dmitriy , Budyukin Aleksey , Kondratyenko Vladimir
Published: December 2024

Purpose: establish the possibility of using freight cars equipped with variable-gauge wheel sets on high-speed railways. Methods: an analysis of modern designs of freight cars created on the basis of passenger cars was carried out, and an analysis of designs of wheel pairs with variable track width was carried out. Results: analysis of the conducted research showed that, due to the practical absence of world analogues, the rolling stock is supposed to be created on the basis of existing passenger electric trains. For high-speed freight railways, it is advisable to use Jacobs bogies and have the same distance between the tracks throughout the entire length of the project, but if the participating countries cannot reach a common agreement, then the rolling stock will require special bogies with wheel pairs that can change the distance, adjusting to the track. Designing freight rolling stock based on existing models of electric trains will reduce costs in design and production, due to the unification of a number of elements of the rolling stock. Practical importance: the use of modern freight cars on the Eurasia high-speed railway, designed on the basis of passenger cars using variable-gauge wheel sets, will significantly increase the speed of freight transportation, increase revenue from the operation of the line, and create a new branch of rail transport — high-speed freight trains.

Published: December 2024

Trochanteric fractures of the femur are a common injury among the elderly, whose average age is over 60 years. In most cases, low-energy trauma forms trochanteric fractures of the femur in elderly patients and cause emergency hospitalization. Therapy of patients with fractures of the trochanteric region should be started immediately after the patient is admitted to the hospital. Today, preference is given to osteosynthesis, in particular osteosynthesis by the dynamic femoral screw system or cephalomedullary fixators. In the absence of consolidation and the development of complications, a more voluminous intervention is performed - endoprosthetics. The purpose of this publication is to demonstrate the success of bipolar hip hemiprosthesis. Materials and methods . We used data from the medical records of the trauma hospital, data from the instrumental study and the results of dynamic observation to write the article. We obtained the results using the equipment of the Center for Collective Use of Scientific Equipment of Derzhavin Tambov State University. Results . The patient underwent surgery: removal of the metal structure, endoprosthesis replacement of the right hip joint. The postoperative period proceeded without complications and on the eighth day the patient was discharged for outpatient observation by a traumatologist at the place of residence. Conclusion . In the absence of fracture consolidation, migration of the metal structure and secondary displacement of fragments after osteosynthesis, it is possible and expedient to perform hip replacement.

The rapid growth of the business world brings significant challenges in terms of legality and morality, particularly regarding the trade of prohibited commodities. Although such businesses are considered illegal in many countries, their circulation continues to expand. The trade in prohibited commodities, such as drugs, alcoholic beverages, and other forbidden products, not only violates national laws but also contradicts the principles of Sharia economic law. This study aims to examine how Sharia economic law views the trade of prohibited commodities from an ethical perspective and how Islamic norms can uphold moral principles and justice in global trade. The research employs a qualitative method with an in-depth literature review approach, drawing on various references related to commodity trade and Sharia economic law. The findings indicate that Sharia economic law emphasizes the importance of justice, welfare, and the prohibition of harmful practices such as usury (riba), uncertainty (gharar), and gambling (maysir). Any form of trade containing elements of harm (mafsadat) to society is prohibited in Islam. In conclusion, the Sharia economic law approach offers a strong ethical foundation to prevent the circulation of prohibited commodities and encourages the establishment of a more just and moral economic system.

This research was motivated by the large number of traders at the Sayang- Sayang market who sell fish but some of them still do not fulfill the terms and conditions of buying and selling. Such as reducing the weight of fish scales so that one party suffers a loss because they are not honest in their buying and selling transactions. The focus studied in this thesis is (1) What are the factors that cause sellers to cheat in fish buying and selling measurements? (2) How does sharia economic law review the practice of buying and selling fish?
The type of research used in this research uses qualitative research. The data collection methods used were observation, interviews and documentation. The analytical method used is qualitative analysis in the form of data reduction, data display, and drawing conclusions. The results of the research show (1) The factors that cause traders to cheat in buying and selling fish using a measuring system are lack of knowledge and understanding regarding appropriate scales, lack of socialization from the government, lack of public awareness of the role of religious figures regarding scales that are in accordance with Islamic law. (2) the practice of buying and selling fish using this measuring system partially meets the requirements for legal buying and selling. However, there are also some who have not fulfilled it. One of the buying and selling conditions that has not been fully fulfilled in the practice of buying and selling fish using this measuring system is the lack of clarity in the goods being traded in terms of substance, form and level.

Published: December 2024

Religious moderation is an important element in maintaining social harmony amidst the plurality of Indonesian society. This article aims to analyze the application of religious moderation in the Sasak community, Lombok, using Pierre Bourdieu's habitus theory as an analytical framework. This study uses a qualitative method based on literature review to explore the interaction between local traditions and religious values ??in shaping the practice of religious moderation. The results of the study indicate that the Sasak community has succeeded in internalizing the values ??of religious moderation through habitus formed from collective social experiences. Values ??such as tolerance, inclusiveness, and mutual cooperation are the main mechanisms in creating social stability amidst the challenges of globalization. In addition, the role of religious leaders, local traditions, and moderation-based education are key factors supporting the success of religious moderation. However, this study also notes obstacles in the form of the influence of globalization, radicalism, and economic inequality that can disrupt social harmony. Thus, religious moderation is not only relevant as a strategy to face global challenges, but also as a foundation for multicultural societies in maintaining social cohesion.

Mesoporous materials have a broad range of applications in industry, and one of which is their potential use in adsorptive separations. This research investigates the use of a secondary amine-functionalized SBA-15 for the separation of a diazo dye, Congo Red (CR), from aqueous solutions. The synthesized SBA-15 was modified with trimethoxy[3-(methylamino)propyl] silane by a post-grafting method. The produced material was characterized using X-ray diffraction, N2 physisorption, scanning electron microscopy, and transmission electron microscopy. The hexagonal mesostructure was preserved after functionalization; however, the specific surface area, pore diameter, and total pore volume of SBA-15 silica decreased. The adsorption of the diazo dye reached equilibrium by 50 minutes, and the data followed pseudo-second-order kinetics. While the yield increased with rising dosage and temperature, it decreased with CR concentration. The maximum adsorption capacity of functionalized SBA-15 (F-SBA-15) for CR uptake was found to be 211.07 mg/g. Thermodynamic data and parameters indicated the potential combination of physical and chemical interactions occurring during the adsorption process. The separation was endothermic and non-spontaneous; the equilibrium data fitted to the Freundlich adsorption isotherm at all tested temperatures. This study demonstrates that the secondary amine-functionalized SBA-15 can be used for the elimination of a toxic anionic diazo dye from aqueous solutions.

A simple and achievable UV-Vis spectrophotometric method for the micro-quantitative determination of quercetin has been developed and validated. This method relies on the formation of supramolecular assemblies of quercetin (QR) and the cationic surfactant cetyltrimethylammonium bromide (CTAB) in a 5 % methanolic aqueous solution. In this solvent medium, CTAB in the presence of QR has a critical micelle concentration of 1.2·10-3 mol l-1 at 24 °C, determined through conductometry. Important analytical parameters such as wavelength, composition of methanol-water mixture, CTAB concentration (cCTAB), and pH were optimized. Under the optimum experimental conditions (l = 397 nm, 5 % methanol as solvent, cCTAB = 2.0·10-3 mol l-1, and pH = 6.0), Beer's law was valid for QR concentrations up to 16.9 mg ml-1. The Ringbom optimum QR concentration range was 1.0 - 16.9 mg ml-1. The method sensitivity was 2.03·104 l mol-1 cm-1 (the molar absorptivity) and 0.13 mg ml-1 (limit of detection). The applicability of the proposed method for quantifying QR in pharmaceutical formulations was demonstrated. Furthermore, the proposed UV-Vis spectrophotometric method was successfully applied to the reliably assay of QR, even in the presence of vitamin C.
