Published: September 2024

This study discusses the distribution of heat in the drum brake system using the experimental method using drums as the braking medium. The test was carried out using the brake test prototype process with the application of press and release. The test data collection technique is using three methods, namely by applying the same amount of press and release of the brake (20 seconds of pressure and 20 seconds of release), the application of press and release of the brake is released more than pressed (30 seconds is released and 10 seconds is pressed), and the application of press and release is more pressed than released (20 seconds pressed and 10 seconds released). The results showed that the highest temperature obtained in the application of brakes for 20 seconds and release for 20 seconds on standard drum brakes reached 61.8 º C, while applying the brakes for 10 seconds and releasing them for 30 seconds reached 46.3 º C, and applying the brakes for 20 seconds and releasing them for 10 seconds achieved a temperature increase of 73.5 º C.

Published: September 2024

This research project surveyed college students about their experiences with online learning in the aftermath of the move to Emergency Remote Teaching (ERT). Specifically, students reported on strategies they appreciate in an online instructor. While students shared varied advice for best practices, their responses confirmed what previous studies have found: especially in this transitional period between ERT and post-pandemic learning, students value instructors who are flexible and empathetic. Additionally, our findings demonstrate that students value engagement (with their instructor, their course content, and their peers), flexible course design, clearly organized learning management systems, and regular communication. This knowledge can be used to guide online educators in course delivery. We recommend that instructors continue to check in with students about their learning needs and requests.
The Impact of Online Learning during the Covid-19 Pandemic on Academic Outcomes for Newly-Struggling High School Students
Authors: Webster Kristine 
Published: September 2024

The Covid-19 pandemic caused worldwide closures of schools resulting in a sudden shift to online instruction for students. For many students, this shift caused a decrease in academic performance. This study was conducted to explore whether particular demographic variables were associated with decreased academic outcomes for newly-struggling students as well as to determine if there was a relationship between these demographic variables and the frequency of D and F final course grades. Student final course grades were collected from a Midwestern United States high school’s student information system. The data were used to compare academic performance between the fall semester of 2019 during in-person learning and the fall semester of 2020 when the Covid-19 pandemic resulted in school closures and a shift to online learning. Logistic regression analysis was used to answer each of the research questions. The findings from this study suggest that there was a significant relationship between low household income status and status as a newly-struggling student. Additionally this study suggests a significant relationship between low household income status and an increased frequency of D and F final course grades between semesters when compared with sample group peers. Conversely, while special education students did see an increase in frequency of D and F final course grades between semesters it was a significantly lower increase between semesters than their newly-struggling sample group peers.

Published: September 2024

Self-regulated learning intervention studies influence students’ learning outcomes in online and blended environments. Reviewing the national literature about self-regulated learning strategies, studies have indicated both significant and insignificant effects on learning outcomes in online and blended environments. The aim of this study is to calculate the common effect size of empirical studies conducted out between 2017-2022 that investigated the effect of self-regulated learning strategies on learning outcomes in online and blended environments, and to determine whether the common effect size shows a significant difference in terms of course type, self-regulated learning strategy type, school level, and learning context. A meta-analytical review method was employed to combine the outcome of independent empirical studies. The studies included in this review were collected from Scopus, IEEE Explore, and ERIC databases. A total of 15 studies included in this study. Cohen’s d coefficient was calculated for the effect size in this study. As the heterogeneity among the effect sizes of the studies was high (Q > χ2, p < .05), the common effect size was calculated in accordance with the random effects model. As a result of the meta-analysis, it was determined that self-regulated learning strategies had a “moderate” effect (Q= 0.65) on learning outcomes in online and blended environments. Moreover, the calculated common effect size showed no significant difference according to the type of self-regulated learning strategy, course type, school level, and learning context.
Habitat Structure Impact on the Occurrence Preferences and Behaviour of the Endangered Species Hipparchia hermione (Lepidoptera, Nymphalidae) in Slovakia

Published: September 2024

Abstract
The aim of this study is to elaborate on the prior information about Hipparchia hermione ecology, examine its behaviour and find the habitat preferences of the species in specific study areas. The obtained results contribute to better management and conservation of the species and its habitats in Slovakia. Six types of behaviour were observed, with the exception of courtship dances, mating and perching. The most common types of behaviour observed were flight and food intake. The RDA analysis of behaviour and environmental variables resulted in a positive effect of free substrate and tall-herb vegetation on H. hermione abundance. The free substrate had a significant positive effect on all types of H. hermione behaviour. The results of the RDA analysis indicate butterflies’ shrub preference. The notion of shrubs’ presence having a positive effect on the representation of H. hermione is supported by another data set, according to which shrub vegetation provided ideal conditions for all types of observed behaviour. The abundance and diversity of nectaring plants did not have a statistically significant effect on species representation. Due to the environmental variables, the tree crowns’ significance plays a vital role. The average values are of 50%. The number of H. hermione individuals in the study areas increased with the growing number of tree trunks over 20 cm and heights over 3 m and the growing number of caterpillar host plants (Festuca ovina). The data show that Hipparchia hermione butterflies depend more on the spatial and structural arrangement of the forest than on abundance or diversity of the flora in the study areas.

Summary
In this article we continue our proofs on integrals of continuous functions of three variables in Mizar. In fact, we use similar techniques as in the case of two variables: we deal with projections of continuous function, the continuity of three variable functions in general, aiming at pure real-valued functions (not necessarily extended real-valued functions), concluding with integrability and iterated integrals of continuous functions of three variables.
Embodying scenes of moral disorder: Bodily gestures as a site of signification in feminist TikTok activism
Authors: Sigurdardottir Heba , Rautajoki Hanna 
Published: September 2024

Abstract
Platformisation has facilitated the emergence of new rhetorical spaces where activists can creatively structure and present their political statements according to medium-specific affordances. In this article, we examine a group of activists on TikTok who topicalise gender-based violence and gender inequality through multimodal means of communication in short videos. We approached these videos as rhetorical arenas for communicating compelling messages with the aim of appealing to the audience. We used digital ethnography, multimodal discourse analysis, and approaches to the mediality of the body to conduct our investigation and analyses. Our results explicate how affective cues and bodily signals are put to rhetorical and political use in TikTok stories to pursue social change. That is, bodily performances stage interrelational positionings in a visual format, conveying affective evaluations and judgements about the state of the world and forming rhizomatic threads of messages to mobilise support and to affirm identification among the members of the movement.
Veiling as free choice or coercion: Banal religion, gender equality, and Swedish identity on Instagram
Authors: Lövheim Mia , Jensdotter Linnea 
Published: September 2024

Abstract
In this article, we analyse implicit connections between gender equality and particular forms of religion in Sweden, as expressed in political discourse and social media debates. Instagram posts responding to the Christian Democrats [Kristdemokraterna] political party's proposal to ban the wearing of veils in Swedish primary schools in 2021 were analysed through methods of co-occurrence analysis and feminist critical discourse analysis. By applying the concept of banal religion from mediatisation of religion theory, the results reveal how implicit connections between veiling as opposed to gender equality in the proposal turn into explicit debates on Instagram regarding what kind of religious practice is compatible with Swedish identity and values. This reveals the ambiguous nature of Instagram as a digital platform that may enhance hegemonic ideas of gender, ethnic, and religious identities, but that may also enable Muslim women to challenge understandings of Islam and gender equality in the public debate.
Fantasised and fantastical Nordic imaginaries: Contextualising Nordic life vlogs by East Asian YouTube vloggers
Authors: Lee Jin , Abidin Crystal 
Published: September 2024

Abstract
Nordic life vlogs are a popular genre among avid watchers of YouTube influencers across East Asia. The vlogs showcase “a slice of life” content, documenting the simple living, daily routines, beautiful landscapes, cultural festivals, and everyday norms of what it is like to live in the Nordic region. While there are many Nordic life vloggers, in this article, we focus on a subset: young immigrant women from Japan and South Korea living in the Nordics. By attending to the genre, content, and interactions between vloggers and viewers, we explore how female East Asian YouTube vloggers who have immigrated to Nordic countries construct fantasised and fantastical narratives around Nordic imaginaries. The discussion of multifaceted layers of Nordic imaginaries explains how Nordic life vlogs serve as a platform for young East Asian women to project their desire for a better life and cultivate subtle resilience at the juncture of postfeminism and postcolonialism.

Published: September 2024

Objective: The objective of this study is to investigate the catalytic capacity of cerium, copper and niobium oxide catalysts in the oxidation reaction of acetonitrile, in order to test the catalytic behavior, conversion and selectivity of the catalysts; evaluate the different proportions of niobium used (0, 15, 30, 50 and 75% m.m) and compare the catalytic performance of the synthesized materials with other studies present in the literature.

Method: The catalysts were synthesized using the one-step polymerization method and were characterized using XRD and H2-TPR techniques. Then, they were applied in the acetonitrile oxidation reaction to be evaluated for conversion and selectivity.

Results and Discussion: The results obtained revealed that the catalysts played a significant role in the proposed reaction, obtaining good conversion and selectivity values, including the production of N2 as the majority.

Research Implications: Considering that the oxidation of acetonitrile generates polluting gases from nitrogen compounds, the research presents a method that produces an extremely low quantity of these pollutants. This method ensures better product quality, reduces energy consumption due to the lower reaction temperature and uses cheaper and more viable catalysts.

Originality/Value: This study contributes to the literature by being based on compounds not yet used together as catalysts and also for the proposed reaction. The relevance of the use of the catalyst is demonstrated through the results obtained, such as high conversions and selectivities to desirable products.

Published: September 2024

This paper presents a large vacuum facility (6-ft-diameter, 10-ft-long chamber) equipped with a magnetic filter-type low Earth orbit plasma source. A recommended operating envelope for the plasma source was established through single-point measurements by varying the discharge currents of the plasma source and the gas flow rates. A three-axis translation stage was fabricated and tested with 2D and 3D scans of the simulated plasma environment. The measured plasma density during this study was between [Formula: see text] for the electrons and [Formula: see text] for the ions, whereas the electron and ion temperatures ranged from 0.55 to 2.06 eV and 1 to 3 eV, respectively. The simulated plasma environment compares well with orbital equivalents, specifically the F layers of the ionosphere.
