Abstract
Car cooling systems are essential equipment to make passengers comfortable, but their energy consumption is very high. Thermoelectric technology has been widely applied as a cooler in many applications, but its use as a car cooler has not been widely used. This research aims to conduct a preliminary study using thermoelectric coolers (TEC) as alternative coolers in pickup cars and to investigate the effect of thermoelectric module and heat exchanger configurations on cooling systems performance. A-TEC cooling system usually uses conventional heat sinks on the cold side and hot side of the TEC. In this study, heat pipes are used as heat exchangers on the hot side of TEC to improve its performance. The cooling system consists of 2 units installed at the rear of the pickup car cabin. Tests were varied using 2 TEC modules arranged in series and 4 TECs arranged in parallel thermal and electrical series. The results showed that using two cooling system units consisting of four TEC modules equipped with heat pipes was able to cool the temperature of the pickup car cabin at 27.4 °C and obtained the highest COP value of 1.16. It shows heat pipes can enhance TEC cooling system performance, producing lower cabin temperatures than conventional heat sinks.

Abstract
Scientific literacy competencies are imperative in contemporary education. Nonetheless, students’ proficiency in scientific literacy remains subpar. The adoption of SSI integrated PjBL-STEAM is still infrequent in endeavors to enhance scientific literacy abilities. Therefore, this study seeks to assess the efficacy of employing SSI integrated PjBL-STEAM in bolstering students’ scientific literacy skills, specifically focusing on the topics of energy and simple machines. The research methodology employed is quasi-experimental, utilizing a match-only pretest-posttest control group design, conducted among eighth-grade students at Laboratory UM Junior School, Indonesia. The assessment tool utilized is a scientific literacy proficiency test, demonstrating a Cronbach’s Alpha coefficient of 0.807. Data analysis involved t-tests, Mann Whitney tests, and N-gain calculations. The findings indicate that the implementation of SSI integrated PjBL-STEAM positively influences students’ scientific literacy skills. And the recommendation is the future research may implement the integrated PjBL-STEAM SSI model in different subjects that have complex characteristics, require strong conceptual understanding, and are related to daily life.

Abstract
Laser powder bed fusion is a mainstream additive manufacturing technology widely used to manufacture complex parts in prominent sectors, including aerospace, biomedical, and automotive industries. However, during the printing process, the presence of an unstable vapor depression can lead to a type of defect called keyhole porosity, which is detrimental to the part quality. In this study, we developed an effective approach to locally detect the generation of keyhole pores during the printing process by leveraging machine learning and a suite of optical and acoustic sensors. Simultaneous synchrotron x-ray imaging allows the direct visualization of pore generation events inside the sample, offering high-fidelity ground truth. A neural network model adopting SqueezeNet architecture using single-sensor data was developed to evaluate the fidelity of each sensor for capturing keyhole pore generation events. Our comparative study shows that the near infrared images gave the highest prediction accuracy, followed by 100 kHz and 20 kHz microphones, and the photodiode sensitive to processing laser wavelength had the lowest accuracy. Using a single sensor, over 90% prediction accuracy can be achieved with a temporal resolution as short as 0.1 ms. A data fusion scheme was also developed with features extracted using SqueezeNet neural network architecture and classification using different machine learning algorithms. Our work demonstrates the correlation between the characteristic optical and acoustic emissions and the keyhole oscillation behavior, and thereby provides strong physics support for the machine learning approach.
Transitioning the grid for climate change: power transmission futures and grid justice
Authors: Ventrella Jennifer , Knuth Sarah 
Published: October 2024

Abstract
Amid the ongoing international boom in renewable power generation, debates over the future of the grid are gaining increasing attention in the United States and beyond. Climate change poses parallel but entangled questions for the large-scale movement of electricity. On the one hand, grid operation is a profoundly altered undertaking in renewables-dominated grids, bringing new management challenges around multi-directional flows, variability, bids for long-distance renewable power transmission, and more. On the other hand, electricity operators and users simultaneously face new climate-related disruptions, repair needs, and risks. In this paper, we explore an important set of energy and climate justice debates emerging around these combined decarbonization and grid resilience challenges, particularly concerns related to high-voltage transmission in the United States and other countries with developed but aging grids. We consider questions of transmission grid (1) access, (2) ownership, (3) siting, and (4) scale/rescaling. We illustrate these issues via the exemplary case of New York State, as the state has become a high-profile focus for debates around grid congestion, rising financial sector ownership of transmission projects, and siting justice issues, as well as for varying progressive alternatives in campaigns for both large-scale public power and decentralized ‘non-wires’ solutions.
Tracing the Natural Body for More Inclusive and Equitable CI Futures
Authors: Prichard Robin Raven 
Published: October 2024

Abstract
Through the legacies of somatics and modern dance, Contact Improvisation (CI) has adopted eurocentric assumptions about a presumed natural body, and these concepts have negatively impacted inclusion and equity in CI. In this chapter, the author traces the concept of the natural body through the developments of modern dance and somatics to illuminate how the natural body transmits ideas of race, gender, class, and liberation. The chapter then demonstrates how the natural body transforms into the neutral body and continues to assert influence on CI. The author identifies ways in which current CI practices reinforce or repudiate conceptions of the natural/neutral body, leading to the question: how can the exclusion and inequity that are caused by conceptions of the natural body be attenuated, negotiated, and ultimately changed? Thus, the author argues that through analyzing and challenging the natural body, CI can address its past to make equitable and inclusive choices for the future.
Queering Contact Improvisation with Sara Ahmed (and the Wheelchair)
Authors: Polo Mª Paz Brozas 
Published: October 2024

Abstract
This chapter proposes an approach to the concept of Contact Improvisation through Sara Ahmed’s Queer Phenomenology. Starting from the suggested dialogue between bodies and objects, in which the spatial and the social are intertwined, this chapter explores the term queer and the collective practice of improvisation as an experience of disorientation, co-perception, and inclination. Instead of the table invoked by Ahmed, one delights in the wheelchair, an iconic object in the history of Contact Improvisation, whose artistic experimentation allows one to imagine other directions in dance and other contact policies.
Se propone un acercamiento al concepto de Contact Improvisation a través de la Fenomenología Queer de Sara Ahmed. Partiendo del diálogo sugerido entre cuerpos y objetos, en el que se entrelazan lo espacial y lo social, este capítulo explora el término queer y la práctica colectiva de la improvisación como una experiencia de desorientación, co-percepción e inclinación. En lugar de la mesa invocada por Ahmed nos deleitamos en la silla de ruedas, un objeto icónico en la historia de la improvisación de contacto, cuya experimentación artística nos permite imaginar otras direcciones en la danza y otras políticas de contacto.
Some unique anatomical scaling relationships among genera in the grass subfamily Pooideae
Authors: Spitzer Daniel B , Ocheltree Troy W , Gleason Sean M 
Published: October 2024

Abstract
Members of the grass family Poaceae have adapted to a wide range of habitats and disturbance regimes globally. The cellular structure and arrangements of leaves can help explain how plants survive in different climates, but these traits are rarely measured in grasses. Most studies are focussed on individual species or distantly related species within Poaceae. While this focus can reveal broad adaptations, it is also likely to overlook subtle adaptations within more closely related groups (subfamilies, tribes). This study, therefore, investigated the scaling relationships between leaf size, vein length area (VLA) and vessel size in five genera within the subfamily Pooideae. The scaling exponent of the relationship between leaf area and VLA was -0.46 (±0.21), which is consistent with previous studies. In Poa and Elymus, however, minor vein number and leaf length were uncorrelated, whereas in Festuca these traits were positively correlated (slope = 0.82 ± 0.8). These findings suggest there are broad-scale and fine-scale variations in leaf hydraulic traits among grasses. Future studies should consider both narrow and broad phylogenetic gradients.
Multimodal Academic Discourse Socialization: Examining Geoscience Students’ Disciplinary Knowledge Construction and Socialization at a Canadian University
Authors: Yamamoto Masaru 
Published: October 2024

Abstract
This ethnographic multiple-case study examines how undergraduate students are socialized into the disciplinary norms, values, and practices of a geoscience course at a Canadian university. Transcending logocentric assumptions about academic discourse, this article advances a broader domain of inquiry––multimodal academic discourse socialization––which foregrounds the polysemiotic nature of academic socialization. This approach examines not only linguistic but also a wider range of semiotic resources, including gestural, visual, material, and spatial ones, among others. To understand geoscientists’ disciplinary norms, values, and communicative practices, ethnographic data (classroom observations, semi-structured interviews, course-related artefacts) were thematically analysed. Focal students’ geoscience poster presentation performances were also analysed using multimodal interaction analysis to scrutinize micro-level instantiations of disciplinary practices. Findings highlight how students were socialized into geoscience ‘observations and interpretations’ through a recurrent multimodal classroom activity, which was also reflected in micro-level multimodal practices enacted in students’ geoscience poster presentations. This study emphasizes that multimodal enactments constitute a crucial dimension of disciplinary practices and values connected with learning to think, view, and represent knowledge as geoscientists.

Abstract
Primary Sjögren’s syndrome is a chronic inflammatory disease characterized by the destruction of exocrine glands. We have previously shown significantly upregulated levels of CXCL10 and CCL3 chemokines in saliva from Sjögren’s syndrome patients. In this study, we examined the expression pattern and localization of these chemokines at the site of inflammation in patients’ minor salivary glands using novel RNAscope® in situ hybridization. Minor salivary glands from 33 primary Sjögren’s syndrome patients and 22 non-Sjögren’s syndrome (non-SS) sicca controls were included. The biopsies were formalin-fixed, paraffin-embedded, and histopathologically evaluated. The CXCL10 and CCL3 mRNA expression in the glandular tissue was investigated using reverse transcription quantitative real-time polymerase chain reaction followed by an RNAscope® in situ hybridization. The mRNA expression of CXCL10 was higher than CCL3 in all patients. Significantly elevated expression of CXCL10 and CCL3 was detected in patients that also expressed autoantibody positivity and a positive biopsy for mononuclear cell infiltrates when compared with non-SS sicca controls. CXCL10 was localized as clusters within focal infiltrates as well as adjacent to acinar and ductal epithelium, while CCL3 was expressed as scattered single mRNA molecules in focal infiltrates and in acinar cells. Our findings suggest CXCL10 as a possible disease biomarker in primary Sjögren’s syndrome due to its upregulated expression in both saliva and minor salivary glands of patients and the localization in the tissue. This should be re-assessed in a larger primary Sjögren’s syndrome patient cohort, followed by additional functional studies to further validate its potential as a disease biomarker.

Abstract
Granulomatosis with polyangiitis (GPA) is a B-cell-mediated, relapsing, autoimmune disease. There is a need for novel therapeutic approaches and relapse markers to achieve durable remission. B cells express immune regulatory molecules that modulate their activation and maintain tolerance. While recent studies show dysregulation of these molecules in other autoimmune diseases, data on their expression in GPA are limited. This study aimed to map the expression of surface immune regulatory molecules on circulating B-cell subsets in GPA and correlate their expression with clinical parameters. Immune regulatory molecule expression on circulating B-cell subsets was comprehensively examined in active GPA (n = 16), GPA in remission (n = 16), and healthy controls (n = 16) cross-sectionally using a 35-color B-cell-specific spectral flow cytometry panel.
Our supervised and unsupervised in-depth analysis revealed differential expression of inhibitory and stimulatory immune molecules on distinct B-cell populations in GPA, with the most notable differences observed in active GPA. These differences include the upregulation of FcγRIIB on nonmature B cells, downregulation of CD21 and upregulation of CD86 on antigen-experienced B cells, and elevated CD22 expression on various populations. Additionally, we found a strong association between FcγRIIB, BTLA, and CD21 expression on specific B-cell populations and disease activity in GPA.
Together, these findings provide novel insights into the immune regulatory molecule expression profile of B cells in GPA and could potentially form the foundation for new therapeutic approaches and disease monitoring markers.
Telemedicine and time management in primary care
Authors: Keshet Yael , Popper-Giveon Ariela , Adar Tamar 
Published: October 2024

Abstract

Background
Information and communication technologies (ICTs) can enable workers to structure work in novel ways, allow for better time management, and increase work scheduling autonomy. Time management and work scheduling are important factors in the field of clinical practice in primary care. Time limits on consultation are a key constraint on the delivery of good care since the length of patient–physician consultation impacts its quality.

Objectives
This research aimed to examine the experiences of primary care physicians (PCPs) when using telemedicine technologies (TTs), a type of ICT, in their communication with patients.

Methods
During 2023 in-depth interviews were conducted with 20 Israeli PCPs: family physicians and pediatricians.

Findings
Perception and management of time emerged as a focal subject in the interviews. The PCPs interviewed described several effects of TTs on time management in primary care. They portrayed TTs as saving time for patients and having a mixed effect on the healthcare organization: both saving and wasting their work time. TTs were described as impacting their time management in the context of work-life balance, allowing them to manage their time during and between appointments.

Discussion
For PCPs, TTs can be beneficial for managing time in the clinic, which can contribute to better healthcare. This article, concerning TTs as a type of ICT, contributes to the existing literature which suggests that ICTs can allow for better time management and increase work scheduling autonomy. It also presents several recommendations for better implementation of TTs in healthcare organizations.
Alfonso Nitti’s Inertia or Impotentiality: Reconsidering Ineptitude in Italo Svevo’s Una vita
Authors: Valentini Teresa 
Published: October 2024

Abstract
The term ‘inetto’, on which Italo Svevo’s entire critical and literary tradition has been based, is mostly absent from Svevo’s texts with a few exceptions. Despite this low frequency, ‘inetto’ has become the adjective most used to define his characters. Surprisingly, Svevo scholarship has not yet focused, intensively and extensively, on those terms that the author did use to describe his protagonists: ‘inertia’ and ‘inert’. The goal of this article is twofold. On the one hand, it aims to reconsider the veil of negativity that still saddles the category of ineptitude. At the same time, in order to achieve this aim, it rethinks this category by means of the neglected concept of inertia. By so doing, it not only rectifies the idea that the term ‘inetto’ is the primary correlative to describe Svevo’s characters, but also allows us to reimagine forms of impotentiality in a positive light.

Published: October 2024

Abstract

Background
Sexual health is an imperative area of study in medical school education, yet many medical schools do not offer a comprehensive curriculum nor is it standardized across the United States (US).

Aim
This study aims to assess written curriculum materials from sexual health curricula in medical schools across the northeast region of the US and compare the current teachings to suggested standards.

Methods
A compilation of academic resources including lecture materials and syllabi were systematically reviewed utilizing a standardized and validated rubric with variables assessed including: biological and psychological aspects of human sexual development, anatomy and physiology of the human sexual response cycle, sexual health in relation to human reproduction, and contraceptive options. We analyzed our data from the document analysis to look at the frequency of inclusion and exclusion of the sexual health topics included in our rubric.

Outcomes
The outcomes of our data set were in line with our hypothesis that there is significant variance between sexual health curricula across institutions as well as an overall lack in material covering sexual health topics.

Results
The data show significant sex specific differences such that male-specific topics were covered more frequently than female-specific information. Additionally, only one of the 10 schools examined taught about vulvar conditions. There was also a paucity of information about sexuality in the post-partum period.

Clinical Implications
The clinical implications of this study aim to highlight the discrepancy between an ideal sexual health curriculum and what is actually being taught in medical schools and help to guide future work of creating a comprehensive and standardized sexual medicine education in US. medical schools.

Strengths and Limitations
The validity of this study was strengthened by analyzing direct curricula materials as opposed to previous use of subjective, self-reported questionnaires. However, the sample location being restricted to the Northeast was a limitation to generalize findings across the country. Future studies would aim to analyze medical school curricula across different regions in the US.

Conclusion
This study shows that there is a lack of comprehensive and standardized sexual health curriculum in medical schools in the Northeastern US and serves as initial evidence for further investigation of this topic across American medical schools.
