Authors: Кропотова Светлана Сергеевна , Кузнецов Гений Владимирович , Дорохов Вадим Валерьевич
Published: September 2022

Приведены результаты численных и экспериментальных исследований концентраций основных компонентов продуктов пиролиза горючего строительного и отделочного материала (на примере древесины). Установлены значения времени задержки срабатывания пожарных извещателей перспективных типов. Показано, что обнаружение газообразных продуктов пиролиза с использованием газоанализатора и пожарных извещателей пламени происходит за существенно меньшее время по сравнению со временем их обнаружения тепловыми и дымовыми извещателями. На основе результатов анализа концентраций газов в непосредственной близости от изучаемых материалов выделены необходимые и достаточные технические решения по раннему обнаружению возгораний.

The work of fire extinguishing systems or fire brigades usually occurs when damage to health, equipment and personnel has already occurred. Therefore, it is especially urgent to create systems for early detection of fires in buildings according to the gas concentrations. This approach creates objective prerequisites for registering signs of incipient stages of fires. This paper presents the results of theoretical and experimental studies of the concentrations of the pyrolysis products of a potentially combustible building and finishing material (wood). Also, the response times of various types of fire detectors (thermal fire detector, wired and wireless smoke detector, flame fire detector, gas analyzer) were experimentally determined for further comparison of their response inertia. The authors use the box isolated from the external environment (with dimensions of 1,5 x 1 x 1,25 m) for experimental studies. Box includes ventilation system, recording devices (gas analysis system, heat and smoke fire detectors, flame fire detectors), as well as a personal computer for collecting and recording information. The concentration ranges of the pyrolysis products were analyzed using a Test-1 gas analyzer. The mathematical model of thermal decomposition of a solid material permitting to analyze the concentrations of the main products of pyrolysis of a combustible material was developed using a complex COMSOL Multiphysics. The results of experimental research and mathematical modeling are in satisfactory agreement. It is shown that the recording of pyrolysis products of combustible materials occurs in a shorter time (compared to the recording of other signs of fire (smoke formation, rise of temperature). The developed mathematical model can be used to determine the ranges of concentrations of gaseous products of wood pyrolysis.

The development of applied aspects of the phenomenon of self - organization in solving the problem of improving the efficiency of solar converters is considered. It is proved that the creation of self -organized nano - sized semiconductor thermal contacts on t he surface of a solar cell can significantly improve the process of converting solar radiation into electricity . It is shown that such an improvement is carried out regardless of the degree of crystallinity of the substrate material. This makes it possible to use cheap and stably stable technical silicon as a substrate for solar cells, on the surface of which many nanoscale p - n junctions from another semiconductor material are created. It is proved that due to the manifestation of the physical effect of sel f - organization, almost ideal hetero structures with high crystal perfection and high uniformity are realized. The paper defines the cond itions under which contacting semiconductors will be able to form stable and photo - efficient hetero junctions.

Of ‘Spectres’ and ‘Ghosts’: Transitional and Contradictory Identifications with the Founder’s Spirit
Authors: Galois-Faurie Isabelle , Barros Marcos , Grima François
Published: September 2022

In what way does a leader influence an organisation when traces of her/his presence remain after his/her departure? Our paper explores the persistent influence of the spirit of the absent founder on employee identification through the metaphors of the ‘spectre’ and the ‘ghost’. From a single case study, we show that, after a first phase of identity construction and identification of members with the organisational identity established by the founder, his departure leads to changes still influenced by the persistence of the symbolic imprint of his spirit. In a second phase, this influence takes the form of a spectre that remains a malleable reference point and leads to a transitional identification, characterised by the shift between two organisational identities: from the declining old one to the burgeoning new. In a third phase, this conversion is threatened by the symbolic return of the founder, as an imposing ghost, with the announcement of a new company strategy based on the original identity forged by the founder. This return will lead to a process of contradictory identification amongst employees now divided between two organisational identities. Our article contributes to the understanding of the persistence of a founder’s influence by suggesting the existence of two different types of spirit with distinct organisational impacts: the spectre and the ghost. Furthermore, we add to the identity literature by proposing the concepts of transitional and contradictory identification to describe the development of parallel processes of disidentification and identification. Finally, we contribute to research on organisational founders by showing that the return of their ghost may have a negative impact on organisations when employees wish to disengage from the past and engage with new alternative identities.

ANALYTICAL CALCULATION OF SHAFT CURRENTS IN THE MOTORS WITH HOMOGENEOUS YOKE
Authors: Željko Hederić  , Marinko Barukčić  , Krešimir Miklošević
Published: September 2022

Literature dealing with the matter of shaft currents mostly elaborates on the methods of motor diagnostics which only observe and analyse harmonics frequencies characteristic for shaft currents. The analytic calculation of the amplitudes of those currents has not been analysed so far for homogenous yoke motors and, in order for correct protection measures to be undertaken, it is necessary to determine exactly the parameters which influence those currents. Shaft currents are an important component of the currents which electrically damage the bearings and usually represent the dominant contribution. This is especially important for low-voltage induction motors which, according to IEC’s data, are the motors with the widest application range in the industry. In this work, the analytic calculation of shaft currents is explained for those motors.
Education in Preventing & Countering Violent Extremism: Considerations for the Western Balkans
Authors: Arifi Besa
Published: September 2022

Violent extremism in the Western Balkans takes many forms, from Western Balkans foreign fighters recruited to participate in conflicts abroad, including in the Middle East and Ukraine; to ethno-nationalist organizations that spread inter-ethnic hatred, some emanating from and glorifying legacies of conflict spanning back to the breakup of the former Yugoslavia and regional conflicts in the 1990s; to chauvinism and anti-EU and anti-NATO ideas that emerge to become even more serious and with greater consequences for the region and socio-political cohesion and dynamics. As violent extremism continues to evolve and adapt in the Western Balkan countries, efforts to address it must also adjust to new threats from both internal and external sources. Recent research on violent extremism in the Western Balkans, and North Macedonia specifically, suggests that education may be an important tool in addressing violent extremism in the region. Some have suggested educational initiatives may assist in addressing online and offline disinformation and extremist narratives. Furthermore, addressing ongoing issues within ethnically divided educational systems may play an important role in working to address some of the ethnic-based divisions that can contribute to ”othering” dynamics. Others have further suggested that education and other support services can play a role in aiding the transition of those imprisoned on charges related to violent extremism and returning families back into society. As countries throughout the Western Balkans continue to update and revise their national action plans and policies to address violent extremism, greater consideration of the role of education and how it might be integrated into these policies is needed. This publication, based on findings from a large-scale literature review mapping the state of research on education in P/CVE in the Western Balkans and beyond,offers a series of considerations for policymakers and practitioners looking to incorporate education in future efforts to address drivers, both real and potential, of violent extremism in Western Balkan states. While findings from this paper are contextualized within the broader experiences of the Western Balkans, specific examples based on experiences in individual countries, North Macedonia most notably, are detailed to provide an in-depth example of considerations for policymakers interested in further incorporating education into P/CVE plans moving forward.

Migratory Outbursting Quasi-Hilda Object 282P/(323137) 2003 BM80*

Authors: Chandler Colin Orion , Oldroyd William J. , Trujillo Chadwick A.
Published: September 2022

We report that object 282P/(323137) 2003 BM80 is undergoing a sustained activity outburst, lasting over 15 months thus far. These findings stem in part from our NASA Partner Citizen Science project Active Asteroids (http://activeasteroids.net), which we introduce here. We acquired new observations of 282P via our observing campaign (Vatican Advanced Technology Telescope (VATT), Lowell Discovery Telescope (LDT), and the Gemini South telescope), confirming 282P was active on UT 2022 June 7, some 15 months after 2021 March images showed activity in the 2021–2022 epoch. We classify 282P as a member of the quasi-Hilda objects (QHOs), a group of dynamically unstable objects found in an orbital region similar to, but distinct in their dynamical characteristics to, the Hilda asteroids (objects in 3:2 resonance with Jupiter). Our dynamical simulations show 282P has undergone at least five close encounters with Jupiter and one with Saturn over the last 180 yr. 282P was most likely a Centaur or Jupiter-family comet (JFC) 250 yr ago. In 350 yr, following some 15 strong Jovian interactions, 282P will most likely migrate to become a JFC or, less likely, an outer main-belt asteroid orbit. These migrations highlight a dynamical pathway connecting Centaurs and JFCs with quasi-Hildas and, potentially, active asteroids. Synthesizing these results with our thermodynamical modeling and new activity observations, we find volatile sublimation is the primary activity mechanism. Observations of a quiescent 282P, which we anticipate will be possible in 2023, will help confirm our hypothesis by measuring a rotation period and ascertaining the spectral type.
Expected Brightness of Ejecta Caused by the DART Impact
Authors: Zubko Evgenij , Videen Gorden , Zheltobryukhov Maxim , Chornaya Ekaterina , Kochergin Anton , Wada Koji
Published: September 2022

We estimate the volume of material that could be excavated from asteroid Dimorphos and expelled into the surrounding space by the DART impact on 2022 September 26. What emerges from our computations is that the total volume of ejected material could be as high as 5710 m3. Assuming that the fraction of fine-dust particles constitutes 5% of this volume, we estimate the apparent brightness of the ejecta to be (6.5 ± 1.5) mag in the V filter. This makes ground-based astronomical observations of the DART impact on asteroid Dimorphos with small telescopes feasible.
Bistability of the Atmospheric Circulation on TRAPPIST-1e

Published: September 2022

Using a 3D general circulation model, we demonstrate that a confirmed rocky exoplanet and a primary observational target, TRAPPIST-1e presents an interesting case of climate bistability. We find that the atmospheric circulation on TRAPPIST-1e can exist in two distinct regimes for a 1 bar nitrogen-dominated atmosphere. One is characterized by a single strong equatorial prograde jet and a large day–night temperature difference; the other is characterized by a pair of mid-latitude prograde jets and a relatively small day–night contrast. The circulation regime appears to be highly sensitive to the model setup, including initial and surface boundary conditions, as well as physical parameterizations of convection and cloud radiative effects. We focus on the emergence of the atmospheric circulation during the early stages of simulations and show that the regime bistability is associated with a delicate balance between the zonally asymmetric heating, mean overturning circulation, and mid-latitude baroclinic instability. The relative strength of these processes places the GCM simulations on different branches of the evolution of atmospheric dynamics. The resulting steady states of the two regimes have consistent differences in the amount of water content and clouds, affecting the water absorption bands as well as the continuum level in the transmission spectrum, although they are too small to be detected with current technology. Nevertheless, this regime bistability affects the surface temperature, especially on the night side of the planet, and presents an interesting case for understanding atmospheric dynamics and highlights uncertainty in 3D GCM results, motivating more multimodel studies.

Published: September 2022

Hura crepitans seed oil (HCSO) remains under-utilized, largely due to the scarcity in data regarding its biochemical properties. To investigate the functional and pro-inflammatory responses to HCSO, twenty-four male rats were grouped into four and received compounded diets containing 5%-HCSO; 10%-HCSO; 15%-HCSO; and 15%-AHO (as control) for eight weeks. The functional responses and the expression of pro-inflammatory cytokines and their receptors were appraised. The organ function biomarkers in rats fed with HCSO-supplemented diets were statistically similar to those of control rats, except for uric acid and creatine levels, which were significantly lower in the HCSO-fed groups, and the urea level, which was elevated in all HCSO-fed groups. Also, HCSO significantly downregulated the expression of pro-inflammatory cytokines (TNF-α, IL-1α, IL-1β, and IL-6) and their receptors (IL-1R and IL-6R), when compared to the control group. Our results highlight the reno- and cardio-protective potentials of HCSO, as well as its anti-inflammatory potentials.
Face à la pandémie : réformer l’expérience ? Arne Næss et Spinoza.
Authors: Bedon Marine
Published: September 2022

La pandémie et les critiques de plus en plus radicales d’un modèle de société destructeur de l’environnement nous incitent à relire Arne Næss, fondateur de la deep ecology et spécialiste de Spinoza. En effet, la deep ecology, mouvement environnementaliste et philosophique né en 1972 et qui connaît un regain d’intérêt sans précédent, ne voit d’autre issue à la crise qu’une réorientation substantielle des conceptions et modes de vie fondamentaux de nos sociétés occidentales modernes. Næss construit alors une éthique de l’enrichissement de l’expérience, envisagée dans son caractère gestaltique, qui se dessine comme une actualisation de la réforme gnoséologique et affective que Spinoza déploie dans l’Éthique, et qui doit ouvrir sur des modes de vie fondamentalement différents, durables, écologiques et joyeux.

Le problème qui reste est : comment garantir que cette expérience reste enregistrée dans les discours du temps post-pandémie et continue d’être audible pour, de cette manière, éviter le retour de la fiction de normalité et d’inaltérabilité qui nous capturait ? Comment retenir l’expérience d’un désir qui, du moins pendant cet intervalle, s’est acheminé librement vers d’autres formes de satisfaction et de réalisation ? Il y aura des forces habiles, très bien instruites, étudiant le sujet pour clôturer cette mémoire, la bannir, l’interdire, pour de cette manière garantir la continuité d’une « normalité » que la pandémie avait interrompue. Comment nous préparer pour que l’oubli ne survienne pas ? Mais aussi, comment éviter que la perte de l’expérience accumulée en 2001 ne se produise à nouveau ?.
Administrators Leveraging School Counseling Supports to Address Disparities in School Discipline
Authors: Lopez-Perry Caroline , Hernandez Edwin , Espinoza Enrique
Published: September 2022

Across the nation, various movements have persistently called for the removal of punitive practices in school; this includes removing law enforcement officers (LEOs) and school resource officers (SROs) and prioritizing funding toward student support services. This chapter brings attention to the role of school administrators and how they can leverage and support school counselors to address disparities in school discipline that impact racially minoritized youth. The authors draw on the theory of racialized organizations to demonstrate how schools are a racialized space, as individual agency is constrained or enabled by their social position within the organization, and how schools further reproduce inequity through their unequal distribution of resources. This chapter offers some practical approaches to reveal how school administrators can leverage school counselors to dismantle disparities in school discipline and prioritize practices of care.
Fostering Social Language Learning in Massive Online Courses
Authors: Díez-Arcón Paz , Martín-Monje Elena
Published: September 2022

This study delves into the fostering of social language learning in massive online open courses (MOOCs). These have become hugely popular during the pandemic, and it has been deemed relevant to investigate how the MOOC format can be customised, so that it addresses the specificities of foreign languages. To this end, a MOOC on EFL (English as a Foreign Language) strengthened its communication tools through the use of social media (Facebook and Instagram) and reinforced support in forums, with dedicated facilitators. The research methodology adopted was DBR (Design-Based Research) and data were collected through quantitative and qualitative techniques. The use of these communication tools (social media and reinforced forums) was generally low, but these enhanced features were positively received, and course designers are advised to persevere in this trend and consolidate the educational use of social media to promote online social language learning.

Crisis Management for School Leaders
Authors: Deagle Tracey
Published: September 2022

COVID-19 presented many challenges for school principals in the United States and around the world. Chief among these concerns was teacher turnover. An extensive review of literature, author research, and the author's experience as a school building and district leader was aggregated to report on themes related to fostering a strong P-12 public school climate, aimed at retaining teachers for the benefit of student growth and academic achievement. This information is organized within the Myers four-stage crisis management framework of normal operations, emergency response, interim processing, and restoration in order to explore opportunities for school principals to support teachers before, during, and after a crisis such as COVID-19.
Caught in the Middle
Authors: Marshall Jason Emile
Published: September 2022

The COVID-19 pandemic sent education into a tailspin. It disrupted traditional modes of learning and wreaked havoc on education stakeholders' wellbeing. Amid this chaos, education middle leaders had to find innovative strategies to ensure that high-quality learning continued. Unfortunately, while there is a growing body of literature on senior leadership and managing crises, less is known about the lived experiences of middle leaders while leading during a crisis. Using a narrative research approach, this chapter aimed to contribute to this conversation by telling the story of a midlevel higher education leader in the Caribbean who ‘led from the middle' to ensure that student learning continued during the COVID-19 pandemic. Emphasis was placed on her leadership experiences while navigating the vagaries of the pandemic and the idiosyncrasies of middle leadership. The results revealed the importance of leading with care, leveraging relationships, and having the support of senior leadership to empower middle leaders and provide them with a sense of agency during times of crisis.

Published: September 2022

The chapter presents research on the relationship between the human body and the space implemented by data and digital interfaces. In this relationship, technology plays a mediating role. The research introduces the concept of a digital threshold to an interactive space that has the capacity to preserve the cognitive well-being of users and invite interaction. To do this, some characteristics are identified that can be used in the design with the aim of relating the body to the devices in the space. Pressure stimuli, rhythm, and body symmetry are the components of a natural language capable of activating a natural motorial reaction mechanism. The details of the experimentation carried out and the processing of the data collected through data visualisation are provided to support the argument.

Published: September 2022

Preservation and dissemination of cultural heritage symbolizes a problem already present before the pandemic period and amplified during the COVID-19 crisis. As a result, the dematerialisation of architecture by digital technologies is the approach to connect Society 5.0 and architecture in cyberspace. The ambition of this chapter is to achieve an approach aimed to explain the impact of ICT during the pandemic and post-pandemic period, using HBIM technology, an essential tool for the approximation of Society 5.0 to the tangible smart heritage. On the other hand, the creation of a virtual tour breaks down architectural barriers (physical and spatial) allowing access to all users as a benefit of the dematerialisation of the asset. The work represents the use of technologies to create new knowledge and values, generating connections between people and tangible and non-tangible things.

Authors: Boucher Helene , Lierse Sharon , Marzano Gilberto
Published: September 2022

This chapter discusses how Schafer's approaches to music education can be applied in today's technological era to develop a highly creative workforce. It is anchored in a Bakhtinian dialogism framework as well as in Vygotsky's socio-constructivist theory. The aim of this research is to use and update an existing and successful twentieth-century philosophy of music education in the digital age as a way to provide an innovative approach to creativity that may now reach a wider audience through digital communication. As a result, a dialogical model of creativity through time emerges, in which the past and the future are interlocked and revolve around the axis of the present, and in which there are neither first nor last words.

Published: September 2022

A three-dimensional detailed design procedure is proposed for the internal layout optimization of a co-axial compound rotorcraft. The present design procedure consists of the following two phases. In its first phase, the detailed three-dimensional configuration is obtained by a robust procedure. This procedure constructs the detailed internal layout based on the structural integrity and aeromechanical stability analysis. Along with such, structural optimization is attempted, and the structural weight will become more precise than that estimated by the trend formula. It is found that the first phase has the capability to predict the component weight accurately. And then, the second phase is performed for estimating the more realistic internal layout. The present procedure accounts the volume of the components and the internal layout will be reconstructed by including the realistic component volume. By applying those phases, the internal layout of the compound rotorcraft will become more realistic.

Published: September 2022

As part of the High-Speed, Highly Efficient Rotor (HSHER) program, a novel trailing-edge flap concept is evaluated. A finely tuned internal laminate topology, coupled with a lightweight pneumatic actuation system, enable a performant trailing-edge flap technology that does not require electronic or mechanical actuators within the rotor blade. The trailing-edge flap is experimentally shown to provide a 12 degrees range of motion between the downward and upward deflected configurations under pressures which can be generated passively by the rotation of the rotor blade. The structure is shown to be sufficiently stiff against aerodynamic pressures and moments, is resilient to strains resulting from large blade deflections, and can hold its shape in the event of pneumatic actuator failure. Additionally, the test data confirmed the strong predictive capability of the finite element analysis for highly-compliant laminate designs such as this. The design is highly customizable and can accommodate a wide variety of airfoils, flap parameters, and loading scenarios. Details of the design, fabrication, and testing of the trailing-edge flap are presented.
Examining a Tandem-Rotor Configuration for the Electric Urban Air Mobility Mission
Authors:   University of Maryland, Scott Erik
Published: September 2022

Electric vertical takeoff and landing (eVTOL) vehicles for the urban air mobility mission have seen increased interest in the past five years spurred by rapid improvements in battery and brush-less motor technology. Because of ease of implementation and perceived increase in safety, most designs utilize distributed propulsion through numerous directly-powered small lifting rotors or propellers. This investigation instead considers the largely-overlooked tandem rotor configuration, presents three notional designs, and considers the potential benefits and limitations of such a configuration for the urban air mobility role.

Published: September 2022

To help ensure safe transportation within electric Vertical Take-off and Landing (eVTOL) vehicles the National Aeronautics and Space Administration (NASA) has been developing novel energy absorbing (EA) design technologies to improve crashworthiness within the unique design constraints of these vehicles. As part of this effort, a series of lightweight energy absorbing subfloor concepts were developed for potential use within eVTOL vehicle design. The capability of the subfloor designs was first evaluated through finite element (FE) model simulation in both component and vehicle level impact conditions. Knowledge gained from these analyses were used to iterate upon the design prior to fabrication. Fabrication and testing of the subfloor designs has begun and will be used to verify predicted capability. Results from FE model analysis was used to down select to a final subfloor geometry for additional component level optimization and full-scale test validation.
Development and Evaluation of Coupling Modes and Haptic Functions enabled by Active Inceptor in Cockpits

Published: September 2022

The potential uses of Active Side-Stick Units (ASSU) technology far exceed solely the case of fully programmable haptic feedbacks to one single pilot or the capability to generate haptic cueing for Flight Envelope Protection functions. Indeed, in dual pilot configurations, the capability to electronically link ASSU enables the coupling of the motions of the Pilot Flying (PF) and Pilot Monitoring (PM) controllers and opens potential new modes of communication between pilots, as well as between crew and Automatic Flight Control System (AFCS) when upper modes are engaged. The EFAICTS (Ergonomic impact and new Functions induced by Active Inceptor integration in CockpiTS) project, started in December 2018, received funding from the Clean Sky 2 Joint Undertaking under the European Union's Horizon 2020 research and innovation program under grant agreement No 820884. ONERA was the project coordinator and Safran Electronics & Defense the Topic Leader. The EFAICTS project proposed to develop and integrate coupling and haptic functions for both Pilot/Co-pilot and Crew/Autopilot interactions along a Human-Centered Design approach, in which the end-users (i.e. pilots) were at the heart of the development, from the beginning of the project to the final evaluation phase. The paper focuses on the flight scenarios definition; the PF/PM/AFCS interactions definition; the development of specific haptic feedbacks and ASSU coupling functions. All the concepts developed and assessed through modelling and intermediate tests were finally evaluated by experienced pilots on the ONERA simulation bench. The main results are presented in the paper.

Published: September 2022

In industry, and more particularly in the aviation maintenance industry, Human Factors/Ergonomics (HFE) is increasingly considered by maintainability stakeholders in the aircraft development process. However, most of the stakeholders are not specialized in HFE, therefore the compromise between HFE and design criteria is not optimized. This paper introduces a methodology proposal to enhance integration of HFE in aviation maintenance by maintainability stakeholders without HFE skills and knowledge. This methodology, called PEAM (Preliminary Ergonomics Analysis in Maintainability) will not replace the HFE specialist but will help all maintainability stakeholders to anticipate the maintenance operator's activity in the preliminary phases of aircraft design. This paper will also introduce the first results regarding PEAM deployment efficiency.
Task Analysis and Predictive Workload Modeling for Autonomous Aircraft

Published: September 2022

The desire to transition to single-pilot operations (SPO) has led to research and development of autonomous technologies that can take over tasks normally handled by two pilots and create a new paradigm that supports SPO. To safely achieve single pilot operations (SPO) of an existing dual crew aircraft, the workload split between the two pilots needs to be analyzed and candidate tasks for offloading identified. Simulation is a valuable tool to model different task allocation strategies for such systems. This paper presents the methodology that was used to analyze shared tasks between a two-pilot crew and identify candidate tasks that could be handled by the autonomous system. A simulation tool called Improved Performance Research Integration Tool (IMPRINT), developed by the U.S. Army was used as part of the design process for an autonomous flight control system. IMPRINT was used to guide cognitive walk-throughs and model pilot workload to inform task allocation between autonomy and the human operator. Advantages and disadvantages of this method will be discussed as well as recommendations for future work.
