Who am I and How Should I Engineer? A guide to using ‘deep’ skills such as reflexivity when engaging at the cultural interface to co-design engineering education.
Authors: Nichols Crighton , Brown Gavin , Gonfond Olli Wynyard
Published: January 2025

The purpose of this paper is to encourage all engineering educators in Australia to feel comfortable and confident to collaborate with Indigenous peers at the cultural interface such that, in turn, engineering students are provided with experiences to help them understand and appreciate the contributions of Indigenous Ways of Knowing, Doing, and Being to the engineering profession. We do this by introducing the concepts of culture and identity, including the importance of understanding and connecting to our own culture through reflexive practice, as well as considerations for working at the cultural interface. The importance of reflexivity is highlighted by introducing the concept of ‘deep’ skills – the ability to examine one’s thoughts, feelings, and motivations – to complement the existing ‘hard’ and ‘soft’ skills that engineers learn. We then outline the value to the engineering profession of some key tenets that are common to First Nations Australian cultures and discuss the importance of being an ally. Finally, we offer a framework for respectfully engaging with Indigenous peers at the cultural interface, so they can co-design engineering education together.

Authors: Bingol Mustafa
Published: January 2025

Technological advancements have transformed foreign language learning and teaching practices in the 21st century. Correspondingly, numerous online applications have arisen to meet the needs of English learners, one of which is Quizlet, a virtual vocabulary learning initiative. Having seen the growing popularity of Quizlet, the researcher investigated its effectiveness in developing 60 law students’ lexical competence within 12 weeks in the spring semester of the 2023-2024 academic year at a private university in Iraq. The participants were chosen via convenience sampling to represent the control and experimental groups. Control group students’ vocabulary lessons were based on a paper-based format through coursebooks and worksheets; however, experimental group students’ lessons were enriched with Quizlet to learn legal terminology through flashcards, games, tests, and self-study folders in an Academic English course. Vocabulary exams, questionnaires, and interviews were used to collect data using mixed methods research design principles. Quantitative data were analyzed by SPSS via descriptive statistics or independent samples t-test, respectively; however, qualitative data gathered by interviews were categorized under specific themes through content analysis using MAXQDA. The findings revealed that Quizlet-enriched instruction paid off with higher vocabulary exam marks, satisfaction, and motivation rates. On the other hand, control group students did not progress noticeably. The findings of this study can offer specific implications for educators interested in integrating technological tools into vocabulary lessons.

Published: January 2025

This study examines the Perceived Ease of Use (PEOU), Usefulness (PU), and Risk of Social Media (SM) platforms affect Tribhuvan University students' Satisfaction (SS). Descriptive and analytical research design is utilized employing primary data analysis. The research investigates the impact of these factors on students’ satisfaction. According to the findings, there is a substantial positive link between SS with PEOU and PU of social media. This suggests that satisfaction rises in tandem with perceived usefulness and ease of use. There is less of a link between Perceived Risk and Students’ Satisfaction. PR does not show up as a major predictor, despite regression analysis's additional confirmation of the perceived usefulness and simplicity of use's strong predictive effect on satisfaction. These results add to our knowledge of the variables affecting how students see social media sites and provide insightful information that can be used to improve user happiness in learning environments. By using these data, administrators and faculties may create more successful plans for incorporating social media into the classroom, which will improve students' entire educational experience
Budget Deficit and Economic Growth in Nepal: ARDL Bound Test Analysis
Authors: Kshetri Tilak , Adhikari Shiva Raj , Thapa Sanjeet Singh , Thapa-Parajuli Resham
Published: January 2025

Using budget deficit to grow real gross domestic product (RGDP) is an issue of perpetual economic debate with different theoretical traditions reaching divergent conclusions. Nepal has always had a budget deficit in its modern history, and the role of this deficit in the economy has not been adequately studied. This paper studies how the budget deficit affected economic growth in both short and long periods using the ARDL approach to the bound test. The paper shows that budget deficit positively impacts RGDP in the short-run, i.e., crowding-in effect as described by Keynesian tradition, but has no effect in the long-term supporting the Ricardian equivalence hypothesis. Further, the results show that exports are largely detached from the long-run RGDP despite having a role in short-run economic performance. Private gross capital formation is also important in short and long horizons.

BACKGROUND Serum albumin, because of its anti-inflammatory, antioxidant, anticoagulant and anti-platelet aggregation action has been linked with onset, progression and severity and appears to influence clinical outcomes among Acute Coronary Syndrome (ACS) Patients.
AIMS This study aimed to describe the association of serum albumin levels with clinical characteristics, severity and outcomes among ACS patients in a tertiary tropical hospital in Nepal.
METHODS This was a descriptive cross-sectional study where clinical and angiographic profile of patients presenting with ACS, admitted in BPKIHS between July 2024 and October 2024 were evaluated and analysed in relation to serum albumin levels. Statistical analysis was done using SPSS 23.
RESULTS A total of 100 patients with ACS admitted in the study period were included in the study. Serum albumin levels in ACS didn’t show significant association with age, gender, Killip class or Type of ACS. Risk factors found to have significant association with hypoalbuminemia were hypertension (p 0.001) and dyslipidemia. (p 0.021). Hypoalbuminemia showed significant association with severity of Coronary artery disease in terms of vessels involved (p 0.004) and Gensini Score (p 0.01). Hypoalbuminemia was significantly associated with longer CCU stay (p 0.012) and Hospital stay (p<0.001). Hypoalbuminemia had significant association with Total adverse outcomes (p<0.001) and nonfatal outcome (p <0.001), but no significant association was found with mortality. (p 0.133).
CONCLUSION Lower serum albumin were associated with higher severity of the ACS and in hospital adverse outcomes including higher non-fatal adverse outcomes and higher duration of CCU and hospital stay . Early stratification of disease based on biomarkers can guide early intervention to prevent bad outcomes.

INTRODUCTION Suicide is a critical public health concern and a leading cause of death globally, particularly among individuals with major depressive disorder (MDD). Understanding the prevalence and correlates of suicidal symptoms in hospitalized depressive patients is crucial for effective intervention and prevention strategies. This study aimed to evaluate the prevalence, severity, and associated factors of suicidal symptoms in adult depressive in-patients at Birat Medical College and Teaching Hospital, focusing on gender differences and clinical predictors.
MATERIAL AND METHODS A descriptive, cross-sectional study was conducted over a 1-year period (July 2022 - June 2023). A total of 120 adult in-patients diagnosed with MDD according to DSM-5 criteria were selected using purposive sampling. Data were collected using a structured proforma and the Hamilton Depression Rating Scale (HDRS). Statistical analyses included descriptive statistics, independent t-tests, Spearman’s correlation, and regression analysis.
RESULTS Of the 120 patients, 54% reported suicidal ideation, with a higher prevalence among females (68%) compared to males (44%). Signiﬁcant positive correlations were found between HDRS scores and suicidal symptoms (r = 0.74, p < 0.001). Regression analysis indicated that HDRS scores and duration of illness were signiﬁcant predictors of suicidal symptoms (R² = 0.68, p <0.01).
CONCLUSION Suicidal symptoms are highly prevalent among depressive in-patients, especially in females. The severity of depression and longer duration of illness are associated with an increased risk of suicidal behavior. These ﬁndings highlight the importance of routine screening and targeted interventions in hospitalized patients with MDD.

The globalization of the maritime transport industry requires constant development and modernization of its individual components. In turn, this is predetermined by the appropriate actions of entrepreneurs involved in the maritime transport business and the proper development of a strategy for the operation of ships calling at the ports of both their country and the country to which products are exported.The objectivity of the priority development of subsystems of the maritime transport industry from the standpoint of balanced relations of the subsystems of the world economy and business goals determines the important regularities of relations. At the same time, as a result of the manifestation of the law of large numbers, new tasks arise to optimize relations between states, the natural environment, and the socio-economic system of individual countries and globally. This determines the requirements for strengthening the socio-economic orientation of business activities. At the same time, special attention should be paid to the consequences of the activities of the globalized subsystem as a maritime transport industry. The role of maritime transport in the system of ensuring the stability and efficiency of economic relations of subsystems of the global economy is constantly increasing. At the same time, the influence of sea transport of countries on the socio-economic situation of citizens is changing. The role of the merchant fleet and the development of seaports from the position of natural balance is considered in many aspects. The periodic imbalance of the state of the global maritime trade market makes it necessary to solve a number of socio-economic problems that form an asymmetry in the stability of the growth of the world economy. Therefore, new tasks arise, the solution of which depends on the maritime transport policy of the leading maritime states and international maritime organizations. However, new problems arise from the standpoint of individual business structures and the systematic assessment of consequences.Keywords: maritime trade market, system problems, efficiency, stability, socio-economic status.

Ongoing Challenges in Clinical Precepting: Exploring Solutions for the Shortage of Clinical Practicum Placements for Diagnostic Medical Sonography Students in Canada
Authors: Sawitsky Leah
Published: January 2025

There continues to be an ongoing shortage of diagnostic medical sonographers in Canada. While much focus has been placed on educational institutions opening more spots in their competitive entry programs, this priority ignores a critical piece of the puzzle—the availability of clinical preceptors required to provide the mandatory clinical training for these students to obtain their Canadian Clinical Skills Assessment (CCSA) competencies. Students must obtain their CCSAs to be eligible to write the Sonography Canada written examinations and gain entry-to-practie in the field. To continue to train competent sonographers and open more clinical practicum placements in Canada, clinical preceptors require increased support and training, both from educational institutions and the facilities they work for. The lack of adequate professional training in teaching skills, a lack of scanning time, and minimal support for clinical preceptors has led to a scarcity of clinical spots for sonography students, undermining students’ training and impeding their ability to acquire essential hands-on scanning experience required to meet the Sonography Canada entry-to-practise requirements.
Misgender or out yourself: Vulnerability in pronoun sharing practices
Authors: Brown Cedar
Published: January 2025

This article discusses how the practice of sharing pronouns in introduction rounds can counterbalance the vulnerability of trans people in a system of mutually reinforcing cisnormative social institutions. It allows for the discursive construction of gendered personhood that may not otherwise be recognisable to others in the room, as well as giving institutional authorisation to trans people, thus delegitimising and decentring transphobia. However, pronoun rounds engender a vulnerable space for trans people, who may feel pressure to misgender or out themselves, as well as for others, who may not previously have had to confront their own relationship with gender and pronouns in this way. Drawing on (auto)ethnographic and interview data from both Australia and the United States, this article contends that while pronoun rounds have the potential to be generative and respectful, the realisation of this potential is determined by how they are enacted.

Este artículo analiza cómo la práctica de compartir pronombres en rondas de presentación puede contrarrestar la vulnerabilidad de las personas trans en un sistema de instituciones sociales cisnormativas que se refuerzan mutuamente. Esta práctica permite la construcción discursiva de la persona de género que de otro modo no sería reconocible para el resto en la sala, además de otorgar autorización institucional a las personas trans, deslegitimando y descentrando así la transfobia. Sin embargo, las rondas de pronombres engendran un espacio vulnerable: para las personas trans, que pueden sentirse presionadas a desvelar su identidad o a no revelar los pronombres con los que se identifican; y para otras personas, quienes tal vez no hayan tenido que enfrentarse a su propia relación con el género ni los pronombres de esta manera. Basándose en datos (auto)etnográficos y de entrevistas en los territorios llamados Australia y Estados Unidos, este artículo sostiene que si bien las rondas de pronombres tienen el potencial de ser generativas y respetuosas, la realización de este potencial está determinado por la forma en que se escenifican.

CONTROL OF GASOLINE VAPOR CONTENT IN ORGANIZED EMISSIONS OF GAS STATIONS
Authors: Golinko Vasyl , Zabelina Valentyna
Published: January 2025

Goal. To theoretically justify a method for controlling the content of gasoline vapors in the organized emissions of gas stations across the full range of possible concentrations, in order to determine the volume of petroleum product emissions into the atmosphere.

Methods. The work uses analytical methods of researching the processes occurring in thermocatalytic sensors, based on the main provisions of the theory of heat and mass transfer and molecular diffusion in gases, evaluation and generalization of research results.

The results. It was established that the heat release on the working thermocouple depends on the mass of the fuel components and the product of the lower heat of combustion of the component and its diffusion coefficient. The highest sensitivity of the sensor is characteristic of the most volatile components of gasoline (pentane, benzene, toluene, etc.). For heavier hydrocarbons, the sensitivity of the sensor decreases. The output signal of the thermocatalytic sensor is proportional to the concentration of gasoline vapors in the fuel-air mixture only under the condition that the limiting agent in the mixture that determines the reaction rate is gasoline vapors. Therefore, in order to measure emissions of gasoline vapors in the entire possible range of concentrations, the mixture must be pre-prepared for control by metered feeding into a measuring chamber with both an emissions and atmospheric air sensor. It was determined that the main requirement in this case is to maintain the linearity of the sensor’s output signal across the full range of concentrations, which is achieved under the condition that the diffusion flow of fuel at the maximum possible content of fuel vapors in the emissions does not exceed 80% of the stoichiometric diffusion flow of fuel and oxidizer to the catalytic surface-active element.

Scientific novelty. A condition has been established that minimizes the error in measuring the content of petrol vapors in the organized emissions of petrol stations due to composition changes. Specifically, gas analyzers should be calibrated using a petrol vapor mixture, with the heat release during oxidation on the catalytically active element being close to the average heat release from all components.

Practical value. The conducted studies allow recommending thermocatalytic sensors for use in monitoring systems of organized emissions of oil and fuel facilities, which allow forming and substantiating requirements for standards of losses and maximum permissible levels of emissions, and speeding up the process of development and implementation of effective measures to reduce them.

Key words: emissions, vapors of petroleum products, environment, control, methods, fuel-air mixtures, thermocatalytic sensors.

Authors: Kostenko Viktor , Bohomaz Olha , Sidnei Stanislav , Кutniashenko Oleksii , Tavrel Maryna , Virych Svitlana
Published: January 2025

Purpose. Justification of the effectiveness of the proposed method of retaining irrigation moisture in arable land due to the formation of filter inclusions.

Research methodology. Computer modeling of filtration flows of irrigation water from the surface to the underlying soil layers.

Results. In this article, the authors proposed a method to prevent irrigation water loss in agricultural fields by creating grooves on arable land that have a small open surface area. In order to prevent the walls of the groove from collapsing, the possibility of filling their cavity with small solid burnt mining wastes, which have high filtration properties, was considered. At the same time, filling the void of the groove with a mixture made on the basis of burned waste mass with the addition of bottom sediments raised from reservoirs will also act as a means of increasing productivity. The implementation scheme for arranging irrigation ditches filled with burnt rock in the field, as well as the initial and operational conditions , are substantiated. According to the results of computer and mathematical modeling, using the ANSYS WB program, in a non-stationary setting, qualitative indicators of the water distribution mechanism in the experimental soil fragment were obtained. The wave nature of water migration under the influence of gravitational and capillary forces has been established. The studies show that irrigation water is concentrated in the “groove with rock – moistened soil massif” system, which has the shape of an oval with a limited contact plane with the surface. This determines the low intensity of evaporation, and, accordingly, the effectiveness of the proposed method of retaining water in the arable land by adding solid burnt mining waste.

Scientific novelty. The use of small solid mining waste to create irrigation ditches on arable land is proposed, and qualitative indicators of the water distribution mechanism in the experimental soil fragment are obtained.

Practical significance. The use of small solid mining wastes, which have high filtration properties, to fill the cavity of irrigation ditches on arable land will allow reducing the loss of water to evaporation and improve the physical and mechanical properties of loamy soils.

Key words: mining solid waste, irrigation water, ditch, arable land, loamy soil.

Published: January 2025

Purpose. To study project solutions aimed at improving a comprehensive approach to ensuring fire safety of transformer substations.

Methods. The authors used methods of analysis and synthesis, summarization of materials of scientific works, regulatory documentation, project and technical documentation, probability theory, decision-making theory.

Results. Design work is an important component of the process of designing and building transformer substations taking into account fire safety requirements. Design solutions for the enclosing fire protection structure must include the following sections: 1. Architectural and construction part. 2. Ventilation.3. Power supply and electric lighting. 4. Fire alarm. 5. Automation. The complex of transformer substations, surrounded by fire barriers, taking into account the described project solutions, is transformed from a static construction into a dynamic electrified structure controlled by logical devices. The devices respond to the state of the object’s technological parameters. The design and manufacture of fire barriers should consider analysis of potential threats and risks of fire, fire resistance of the material, design, compliance with safety standards and regulations. A comprehensive approach to ensuring fire safety of transformer substations has been improved.
