Branding of the Arctic Tourism Destinations in Russia
Authors:   Voronezh State University, Voronezh, Russia, TIMOSHENKO Diana S.
Published: March 2021

The study deals with the issues of tourism destinations branding, as well as tourism multidimensionality and tourism destination identity in the Russian Arctic. The factors determining the promotion and branding of tourist destinations in the Russian Arctic are considered in correlation with the fundamental principles of sustainability in Arctic tourism. The relationship between state policy and socio-economic development of the Arctic regions of Russia is considered, in particular, in the aspects of Arctic tourism development. Dialectical, logical, theoretical and empirical methods were conducted for this research. The article defines the conditions for increasing the competitiveness of the domestic tourism product in the Arctic, lists tourism facilities, territories and tourism products that are of the most expressed interest to Russian and foreign tourists. The factors affecting the competitiveness of the tourism product in the Russian Arctic are identified. The article presents the components of the tourist destinations image in the Russian Arctic, which may become the basis for the formation of a strategy for branding tourism in the Arctic regions. The conclusion is drawn about the need for an umbrella brand creation for the Russian Arctic. The necessity of creating conditions for the professional implementation of tourist personnel in the Arctic regions of Russia and the influx of labor resources from urbanized and oversaturated territories to the Arctic with the aim of the integrated development of tourism is substantiated.

Authors:   Road Traffic Section, Business School, Nord University, Bodø, Norway, Katrine Katrine
Published: March 2021

This paper contributes to filling a knowledge gap by presenting new research within the practical field of road transport. It takes the buyers of road transport services as its point of entry and seeks to answer the follow question: How can buyers of road transport services contribute to safe road transport in northern Norway? A qualitative approach was selected for this study, and semi-structured interviews were conducted with six different buyers of road transport services. By using a modified version of The Pentagon Model, different aspects were analyzed in order to identify organizational characteristics and qualities that will improve the possibility for buyers of road transport to contribute to a safer road transport in Northern Norway and thereby contribute to fewer accidents and near-misses. The following characteristics and qualities were identified: 1) the importance of developing a detailed formal contract with the provider of road transport; 2) being aware of the possibilities with new technologies; 3) understanding that the decision criteria for ordering transport can influence road transport safety; 4) seeing the importance of good communication with both the transport organization and the authorities; 5) recognizing that knowledge of and trust in a transport organization is important but could also affect judgement regarding revisions and controls. This study suggests that buyers of road transport services can contribute to a safer road transport in northern Norway by emphasizing these five characteristics and qualities.

Nitrocellulose is cellulose that is titrated into an ester polymer which can be used as a major component in several types of ammunition and explosives and other materials. Hemp (Boehmeria nivea) is a type of fiber plant that is rich in cellulose and thrives in Indonesia. Until now, the need for nitrocellulose in Indonesia is still imported, even though there is a lot of potential for cellulose that can be exploited, one of which is by synthesizing nitrocellulose from the hemp plant. One of the many uses of nitrocellulose derivatives, one of which is propellant. The propellant is the fuel or power source of a rocket engine. Nitrocellulose that can be used for propellants is nitrocellulose with levels between 11-13.3% nitrogen. This study aims to produce nitrocellulose in levels that meet the standards for making propellants. The study was carried out with a cellulose activation procedure using 20% ​​sodium hydroxide and 1 ml of triethylamine per gram of cellulose. Cellulose nitration was carried out using sulfuric acid and nitric acid with the composition of A (1: 1), B (2: 1) and C (3: 1) which were refluxed for 3 hours. Nitrogen determination was carried out using the Kjeldahl method. The results showed that from 3 samples A, B, and C, nitrogen levels were obtained respectively 12.62%, 13.23%, and 12.97%. This shows that the nitrocellulose from the hemp plant (Boehmeria nivea) can be used for propellants.

Published: March 2021

Merkuri merupakan salah satu logam berat yang berbahaya bagi lingkungan. Pemanfaatan bakteri endofit bambu sebagai bakteri pendegradasi logam merkuri belum banyak dilaporkan sehingga perlu dilakukan penelitian untuk memperoleh isolat bakteri endofit bambu resisten logam merkuri. Penelitian ini bertujuan untuk mengetahui resistensi isolat bakteri endofit bambu terhadap logam merkuri. Isolat bakteri yang digunakan merupakan koleksi isolat Laboratorium Biologi STKIP Pembangunan Indonesia, yang diberi kode KL2 A Hitam, KL2 Rehitam, KL2 Blit2, KL2 Rebatik. Pada uji resistensi, sebanyak 100 µL larutan HgCl2 diteteskan pada paper disk yang ditumbuhkan pada media Nutrient Agar sebagai media tumbuh bakteri endofit bambu selama 24 jam pada suhu 37 °C. Konsentrasi HgCl2 yang digunakan adalah 10, 20, 30, 40 dan 50 ppm. Hasil menunjukkan keempat isolat bakteri dapat tumbuh pada seluruh media yang mengandung larutan HgCl2, yang ditandai dengan terbentuknya zona bening di sekitar paper disk. Berdasarkan pengukuran zona bening, isolat KL2 Rebatik membentuk zona bening sebesar 13 mm pada media mengandung 10 ppm HgCl2 dan merupakan zona bening terbesar. Tiga isolat lainnya, isolat KL2 A Hitam, KL2 Rehitam dan KL2 Blit2 pada media mengandung 10 ppm HgCl2 membentuk zona bening masing-masing 10,66 mm dan 7,6 mm. Seluruh isolat bakteri menunjukkan penurunan ukuran zona bening seiring dengan meningkatnya konsentrasi HgCl2 yang digunakan. Hal ini menunjukkan bahwa bakteri endofit bambu resisten terhadap ion Hg2+ hingga konsentrasi 50 ppm. Isolat KL2 Rehitam dipilih untuk diindentifikasi menggunakan amplikasi gen 16S rRNA. Hasil identifikasi menunjukkan isolat KL2 Rehitam memiliki tingkat kemiripan sebesar 99% dengan Bacillus cereus.

Socio-political Discourse Addressing Liberal Values in Russia in the Early 20th Century
Authors: Гаврикова А.С.
Published: March 2021

В статье рассматривается обращение либеральных кругов российской общественности начала ХХ века к исследованию избирательного права, гражданских свобод, организации выборов, проведению политической агитации и британского опыта в этих вопросах. Внутриполитические кризисные явления в России в начале ХХ века и рост революционных настроений сказались на повестке отечественной общественно-политической мысли. Работа первого российского парламента — Государственной думы, и становление многопартийности находились под пристальным вниманием отечественных либералов. Выборы и процесс введения всеобщего избирательного права изучался с учетом уже имеющегося западного опыта, в том числе английского выборного права. Анализируются оригинальные взгляды В. В. Водовозова, Н. И. Лазаревского, В. Ф. Матвеева, В. Ф. Дерюжинского, весьма остро реагировавших на происходящее в стране и проявлявших высокий интерес к изучению британского опыта партийного строительства и демократических ценностей. В кругах либералов появился практический интерес к исследованию политической жизни Великобритании. В статье отражены и обобщены их взгляды на дальнейшую демократизацию России, включение населения в политическую жизнь, расширение политических и гражданских прав и свобод населения, свободы печати, собраний, союзов, петиций.

The article focuses on the way Russian liberals of the early 20th century treated the investigation of suffrage, civil freedoms, election system, political propaganda, and the British election practices. Domestic political problems experienced by Russia in the early 20th century and the proliferation of revolutionary ideas produced a significant impact on the socio-political discourse. The work of Russia’s first Parliament, the State Duma, and the development of a multi-party parliamentary system were scrutinized by Russian liberals. Election practices and the introduction of universal suffrage were assessed against the backdrop of foreign election practices, British election practices in particular. The article analyzes V. V. Vodovozov’s, N. I. Lazorevsky’s, V. F. Matveev’s, V. F. Deryuzhinsky’s views on the changes pervading the Russian political system. It underlines the political philosopher’s keen interest in the investigation of British party practices and democratic values. The article maintains
that Russian liberals were interested in the investigation of British political life. It deals with Russian liberals’ views on further democratization of Russia, people’s engagement in political life, the proliferation of political and civil rights and freedoms, including the freedom of the press, the freedom of assembly, the freedom of association, and the freedom of petition.
Soren Kierkegaard’s Philosophy and its Influence on French Existentialist Novels
Authors: Авраменко В.И.
Published: March 2021

В статье выявляются предпосылки, обусловившие модификацию формы французского философского (экзистенциалистского) романа в середине XX века. На примере творчества Сёрена Кьеркегора показана связь поэтики экзистенциалистского произведения с философией. Определено существенное влияние на творчество французских экзистенциалистов не только идей датского мыслителя, но и соответствующей этим идеям найденной им формы философского поиска. Выявлены особенности этой формы: философское исследование параллельно в художественной и трактатной (или эссеистской) формах, их вступление в диалог, в ходе которого обе части поясняют и дополняют друг друга. Такой способ развития философской идеи и сама специфика экзистенциалистской философии определяют характер философского романа. Исчезает присущая «классическому» философскому роману необходимость прямого изложения идей.
С помощью различных средств развивается выражение философии, а не ее высказывание. Отсюда — исчезновение в романе героя-резонёра, отсутствие исходной философемы (заданности философской проблемы) и другие особенности поэтики, которые еще предстоит изучить. Материалы исследования могут быть использованы при создании учебников и различных пособий по французской и зарубежной литературе, при разработке курсов лекций и практических занятий по литературе в высших учебных заведениях, при написании курсовых и дипломных работ.

The article treats the prerequisites for the transformation of French existentialist novels in the middle of the 20th century. Soren Kierkegaard’s philosophy is used to show the connection between philosophy and existentialist poetics. The author of the article maintains that French existentialist writers were influenced not only by the Danish philosopher, but also by the latter’s method of philosophical inquiry. The author singles out some characteristics of the method: philosophical inquiry develops parallel with literary development, literary and philosophical patterns intertwine and complement each other. The method of philosophical inquiry and the peculiarities of existential philosophy determine the peculiarities of philosophical novels. The direct presentation of ideas typical of classical philosophical novels is no longer required, philosophical expressiveness prevails over philosophical description.
The characters of existentialist novels no longer need to philosophize, philosophical problems don’t have to be set. The materials of the research can be used to create textbooks and manuals on French and
foreign literature, to create lectures and seminars in literature in higher education institutions, to write term papers and graduation papers.
Computation of Steady Free Convective Boundary Layer Viscous Fluid Flow and Heat Transfer towards the Moving Flat subjected to Suction/Injection Effects
Authors: Ferdows M. , Shamshuddin MD. , Zaimi Khairy
Published: March 2021

The steady free convective boundary layer viscous fluid flow and heat transfer towards the moving flat plate is investigated. It is important to study the fluid flow and heat transfer problems in the presence of suction and injection effects due to an extensive variety of applications in engineering and industry. Thus, the main objective of the present study is to analyse the impacts of the suction and injection parameter on the velocity and temperature of the fluid as well as the skin friction and the Nusselt number coefficients. The problem has coupled partial differential equations which are converted into ordinary differential equations by employing similarity transformation and adopting of the strong wall suction. The ordinary differential equations thus obtain are handled numerically by utilizing Maple software simulation. The main findings concerning the behaviours of velocity and temperature against various values of the emerging physical parameter such as suction/injection are presented clearly in this numerical examination via graphical illustrations whose physical explanation are discussed thoroughly based on a strong theoretical basis. Furthermore, skin friction and Nusselt number results are studied at different values of pressure gradient. The detail geometry reveals that the velocity and temperature of the fluid decreases with increase of suction/injection parameter. Both skin friction coefficient and Nusselt number decreases with an increase of suction/injection parameter.

PROCESS IN CONTEMPORARY VISUAL ART AS A PARADIGM SHIFT IN THE VISUAL ART EDUCATION: PERSPECTIVE OF CREATIVITY
Authors: Vuk Sonja , Bosnar Maja
Published: March 2021

The authors discuss contemporary visual art, its creation processes and their implementation in art education in primary and secondary/grammar school. Changing the paradigm of studying from “fine to visual arts” within art education is a process itself. Visual art, which involves a participatory and new media art, is also concerned with processes that establish unique relationships between subjects and their effect on the real life of the participants or audience. It is no longer enough to deal with aesthetic concepts, but it is necessary to use art forms to create everyday life, and deal with ethical concepts. Transferring these processes into education connects students’ creative activities and their everyday life context, so that they can learn how to create social and personal relationships by using images. Experimental research in grammar school affirms the importance of teaching topics as are socially and politically engaged art or artistic activism, mediated by new media. Action research in elementary school affirms proposed style of art education as an acceptable way of transferring the way of thinking from visual art, especially a participatory and new media art, to the process of education as a discovering problems in society and offering solutions represented by visual forms.
Revisiting Newly Large Magellanic Cloud Age-gap Star Clusters
Authors: Piatti Andrés E.
Published: March 2021

Recently, a noticeable number of new star clusters was identified in the outskirts of the Large Magellanic Cloud (LMC) populating the so-called star-cluster age gap, a space of time (∼4–12 Gyr) where the only known star cluster is up-to-date ESO 121-SC 03. We used Survey of the Magellanic Stellar History DR2 data sets, as well as those employed to identify these star-cluster candidates, to produce relatively deep color–magnitude diagrams (CMDs) of 17 out of 20 discovered age-gap star clusters with the aim of investigating them in detail. Our analysis relies on a thorough CMD cleaning procedure of the field-star contamination, which presents variations in its stellar density and astrophysical properties, such as luminosity and effective temperature, around the star-cluster fields. We built star-cluster CMDs from stars with membership probabilities assigned from the cleaning procedure. These CMDs and their respective spatial distribution maps favor the existence of LMC star field density fluctuations rather than age-gap star clusters, although a definitive assessment on them will be possible from further deeper photometry.
Circular Orbit Structure and Thin Accretion Disks around Kerr Black Holes with Scalar Hair
Authors: Collodel Lucas G. , Doneva Daniela D. , Yazadjiev Stoytcho S.
Published: March 2021

In this paper, we first investigate the equatorial circular orbit structure of Kerr black holes with scalar hair (KBHsSH) and highlight their most prominent features, which are quite distinct from the exterior region of ordinary bald Kerr black holes, i.e., peculiarities that arise from the combined bound system of a hole with an off-center, self-gravitating distribution of scalar matter. Some of these traits are incompatible with the thin-disk approach; thus, we identify and map out various regions in parameter space. All of the solutions for which the stable circular orbital velocity (and angular momentum) curve is continuous are used for building thin and optically thick disks around them, from which we extract the radiant energy fluxes, luminosities, and efficiencies. We compare the results in batches with the same spin parameter j but different normalized charges, and the profiles are richly diverse. Because of the existence of a conserved scalar charge, Q, these solutions are nonunique in the (M, J) parameter space. Furthermore, Q cannot be extracted asymptotically from the metric functions. Nevertheless, by constraining the parameters through different observations, the luminosity profile could in turn be used to constrain the Noether charge and characterize the spacetime, should KBHsSH exist.

Published: March 2021

We investigate the mass–velocity dispersion relation (MVDR) in 29 galaxy clusters in the HIghest X-ray FLUx Galaxy Cluster Sample (HIFLUGCS). We measure the spatially resolved, line-of-sight velocity dispersion profiles of these clusters, which we find to be mostly flat at large radii, reminiscent of the rotation curves of galaxies. We discover a tight empirical relation between the baryonic mass M
bar and the flat velocity dispersion σ of the member galaxies, i.e., MVDR,

These characteristics are reminiscent of the MVDR for individual galaxies, albeit at about a ten times larger characteristic acceleration scale. The cluster baryon fraction falls short of the cosmic value, exposing a problem: the discrepancy increases systematically for clusters of lower mass and lower baryonic acceleration.
Evidence for Gas-phase Metal Deficiency in Massive Protocluster Galaxies at z ∼2.2*

Published: March 2021

We study the mass–metallicity relation for 19 members of a spectroscopically confirmed protocluster in the COSMOS field at z = 2.2 (CC2.2), and compare it with that of 24 similarly selected field galaxies at the same redshift. Both samples are Hα emitting sources, chosen from the HiZELS narrowband survey, with metallicities derived from the

M
⊙ ≤ M
* ≤ 1010.9
M
⊙ are metal deficient by 0.10 ± 0.04 dex (2.5σ significance) compared to their coeval field galaxies. This metal deficiency is absent for low-mass galaxies, M
* < 109.9
M
⊙. Moreover, relying on both spectral energy distribution derived and Hα (corrected for dust extinction based on M*) star formation rates (SFRs), we find no strong environmental dependence of the SFR–M
* relation; however, we are not able to rule out the existence of small dependence due to inherent uncertainties in both SFR estimators. The existence of 2.5σ significant metal deficiency for massive protocluster galaxies favors a model in which funneling of the primordial cold gas through filaments dilutes the metal content of protoclusters at high redshifts (z ≳ 2). At these redshifts, gas reservoirs in filaments are dense enough to cool down rapidly and fall into the potential well of the protocluster to lower the gas-phase metallicity of galaxies. Moreover, part of this metal deficiency could be originated from galaxy interactions that are more prevalent in dense environments.
Mean Resultant Length as a Measure of the Lopsidedness of Satellite Galaxy Distributions
Authors: Brainerd Tereasa G. , Samuels Adam
Published: March 2021

We summarize new results for the locations of the satellites of isolated host galaxies that were presented at the 237th meeting of the American Astronomical Society. Using 3575 host-satellite systems, we investigated the spatial distributions of the satellites with respect to their hosts using a Mean Resultant Length (MRL) statistic. In agreement with a previous analysis that relied on a less optimal statistic, we find that the satellites of isolated blue hosts have a strong tendency (>99.9999% confidence level) to be clustered toward one direction relative to their host. This also holds true for the full sample, but is driven by the “lopsidedness” of the satellite distributions around blue hosts. For red hosts (which comprise 76% of the sample), the MRL indicates only a marginal degree of lopsidedness (98.5% confidence level) in the satellite locations.
Dire de faire à des enfants : le rôle de l’architecture textuelle dans des textes injonctifs adressés aux enfants (règles de jeu et consignes scolaires)
Authors: Garcia-Debanc Claudine
Published: March 2021

La mise en forme typodispositionnelle et l’architecture textuelle (Virbel 1985) jouent un rôle important pour la compréhension et la mémorisation d’instructions. La signalisation de l’architecture textuelle se réalise par des marques linguistiques ou par une mise en forme typodispositonnelle (titres, sous-titres, gras, tirets, etc.). Un protocole expérimental portant sur la lecture de règles de jeu par des enfants (9-12 ans) a permis d’évaluer les effets de différentes versions (marquage linguistique vs  typodispositionnel) sur la compréhension des instructions, leur mémorisation à court et à moyen termes ou le temps nécessaire pour retrouver une information, au profit de la version la plus typodispositionnelle. Les particularités des consignes scolaires sont mises en évidence à travers une analyse de leur organisation linguistique et spatiale dans un chapitre de manuel de grammaire de fin d’école primaire.
Alors, là, je vais vous expliquer comment on joue ! Explication procédurale finalisée dans une perspective développementale
Authors: Mazur Palandre Audrey , Colletta Jean-Marc , Lund Kristine
Published: March 2021

Lors de la production d’une explication, les locuteurs sont confrontés à une tâche impliquant deux principaux objectifs : (i) la construction référentielle inhérente à l’objet de l’explication et (ii) la gestion de l’interaction et des interlocuteurs. L’objectif de cette étude est ainsi de voir comment une explication procédurale à enjeu interactionnel est gérée par l’enfant et à partir de quand il commence à maîtriser à la fois les contraintes référentielles et pragmatiques de la production langagière. Pour ce faire, des explications d’enfants âgés de 9 à 13 ans ont été collectées et analysées. Les résultats montrent que l’âge a un impact sur les choix informationnels et gestuels des enfants, que ceux-ci s’appuient sur la modalité gestuelle du langage, différemment selon l’âge, et enfin qu’en grandissant, ils améliorent la gestion des contraintes interactionnelles.
L’ordre de la dette maintenu « whatever it takes » : après l’argent « magique », le retour aux sacrifices ?
Authors: Lemoine Benjamin
Published: March 2021

Avec la pandémie, tout s’effondre. Les politiques de confinement font plonger la croissance et exploser la dette publique à une vitesse record. En trois mois, la dette a augmenté de près de 13 points de PIB pour atteindre les 120 % rapportés au produit intérieur brut, soit le double du seuil européen initialement autorisé dans le traité de Maastricht. Cette accélération est sans précédent dans les annales des statisticiens français. Il faut revenir aux guerres pour retrouver de tels horizons comptables. Mais au milieu de cet effondrement et de cette incertitude radicale, un îlot de croyances et de certitudes persiste : le logiciel disciplinaire arrimé à la dette publique. Les éléments de langage demeurent inchangés et la petite musique de l’austérité a percé.
On a oublié la dimension conflictuelle du care
Authors: Pimentel Lara Rafaela , Orozco Amaia Pérez , Albenga Viviane
Published: March 2021

La crise sanitaire a mis la thématique du care à l’agenda : à l’agenda médiatique par la visibilisation des métiers du soin, désignés comme essentiels et exercés majoritairement par des femmes, mais aussi à l’agenda politique comme en Espagne où le gouvernement d’alliance PSOE-Unidas Podemos propose un « pacte pour le care  ». Or, en Espagne, le care (« los cuidados 1  ») est revendiqué y compris par les franges radicales du mouvement féministe, et fortement associé au mouvement de grève féministe qui a réuni des millions de manifestant·es les 8 mars 2018 et 2019. Mouvements revient sur les implications économiques et politiques de la prise en compte du care comme ensemble d’activités sociales indispensables à la « soutenabilité de la vie » en mettant en regard deux points de vue : celui de l’une des fondatrices du tout nouveau syndicat féministe des employées de maison, Rafaela Pimentel Lara, avec les perspectives théoriques de l’économiste féministe anticapitaliste Amaia Pérez Orozco.
Utiliser la recherche pour soigner le cancer : l’innovation biomédicale localisée
Authors: Besle Sylvain , Schultz Émilien
Published: March 2021

Résumé Cet article montre que le développement des essais précoces dans le domaine de la cancérologie relève d’un processus d’innovation localisée, se démarquant du modèle diffusionniste étudié par la sociologie de l’innovation. Depuis une dizaine d’années, des médecins chercheurs participent à la création d’unités dédiées permettant d’augmenter le nombre d’essais précoces et leur visibilité auprès des patients, ces essais étant considérés comme un traitement potentiel pour des patients en échec thérapeutique. L’enquête réalisée pendant neuf ans auprès de médecins, de responsables politiques et de patients montre que le développement de cette activité de recherche s’appuie sur l’interdépendance entre la conduite des essais, en collaboration avec les industriels du médicament, et la mise en avant de leur valeur clinique. Cette intégration de la recherche biomédicale dans le soin conduit à de fortes disparités à l’échelle du système de santé français, posant la question des inégalités sociales d’accès aux innovations.
Une histoire de la politique arabe de la France
Authors: Boniface Pascal
Published: March 2021

À l’automne 2020, une campagne de boycott des produits français était lancée dans plusieurs pays musulmans pour protester contre l’« islamophobie » qui règnerait en France. Des journaux anglo-saxons déploraient, eux aussi, ce climat antimusulman. Si le président Emmanuel Macron s’élevait contre une telle interprétation, la France, qui il y a une quinzaine d’années encore était le pays occidental le plus populaire dans le monde musulman, semble depuis devenue le plus impopulaire. En la matière, une certaine spécificité historique française semble s’être effacée derrière une conjonction de raisons diplomatiques et de politique intérieure.
Veranear en la calle Florida: instantáneas de Mansilla en Caras y Caretas
Authors: Cabo Mariana de
Published: March 2021

Buenos Aires constituye para Lucio Victorio Mansilla el escenario de sus puestas en escena. Bajo diferentes escenografías y disfraces, compone sus juegos teatrales. Desde 1902, el escritor y periodista se apropia de la ciudad a través de un nuevo medio: la revista Caras y Caretas. Según explica Verónica Tell (2009: 143), el semanario ofrece a la fotografía un lugar primordial. Se trata de una estrategia innovadora que ubica a la publicación en la vanguardia. Mansilla no queda al margen de este nuevo espacio mediático. El escritor se vale del código visual para poblar el imaginario de la sociedad porteña. De esta manera, aunque instalado definitivamente en París desde 1902, a través de las fotografías que publica la revista, Mansilla reafirma su presencia en Buenos Aires. Caras y Caretas se convierte en portavoz de sus idas y venidas a la ciudad. Cada artículo que describe su llegada a Buenos Aires se acompaña de fotografías. Estas imágenes más que ilustrar el texto se vuelven el mensaje principal del artículo.

In the present era, electric vehicles (EV) have revolutionized the world with their dominant features like cleanliness and high efficiency compared to that of the internal combustion (IC) engine-based vehicles. To crave for the higher efficiency of the EV during the braking, the kinetic energy of the EV is converted into electrical energy, which is harvested into storage system, called regenerative braking. Various techniques such as artificial neural network (ANN) and fuzzy-based controllers consider factors like state of charge of the battery and supercapacitor and brake demand for calculating the regenerative braking energy. A force distribution curve is designed to ensure that the braking force is distributed and applied on the four wheels simultaneously. In real-time optimization, an operating area is formed for maximizing the regenerative force which is evaluated by linear programming. It is proved that the drive range of the vehicle is increased by 25.7% compared to the one with non-RBS. In this work, RTO-based control loop for regenerative braking system is simulated in MATLAB/Simulink.

Solar powered wireless electric vehicle charging technology functions independently without interface with the utility grid. Wireless power transfer (WPT) technology is incorporated for wireless charging, which brings the benefits of safe operation, less pollution, and little maintenance cost. WPT technology necessitates no physical connection between the charging device and vehicle, thus hazards and inconvenience produced by conventional charging methods have been minimized. WPT in electric vehicle can be used to reduce the charging time, range, and cost. In this chapter, the various configurations of WPT like inductive, capacitive, resonant, and roadway power transfer techniques have been presented. The small-scale prototype of wireless charging has been developed in the laboratory by incorporating inductive power transfer technique. The experimental results have been presented to validate the feasibility of the system in real time.

Authors: Dennen Vanessa P. , Park Yujin
Published: March 2021

Personal learning networks (PLNs) are a form of informal professional development in which teachers build and maintain connections to other educators and learning professionals and the resources that will meet their personal continuing education needs. Although PLNs can incorporate face-to-face connections, they typically make heavy use of social networking tools for finding and sharing information and educational innovations. In this chapter, the authors discuss how PLNs have been developed and used by preservice and inservice teachers, discussing the similarities and differences between the two groups along with the progression of PLN development from preservice to inservice teacher experiences. Next the authors discuss the role that PLNs play in helping teachers develop their blended and virtual learning knowledge and skills, along with ideas for how teacher-educators and administrators can provide support for this endeavor.
Making Good Use of Pictures
Authors: Nuhoğlu Kibar Pınar , Pettersson Rune
Published: March 2021

Pictures have been important for communication for thousands of years. It is easy for students to lose interest in learning materials with complicated content. Visuals may have many functions, such as attract, gain, get, hold, and maintain attention of a learning material. In contrast to pictures used for advertising, decoration, and entertainment, the main purposes for use of visuals in education are cognitive and pedagogical. Our use of pictures must always be adapted to the intended audiences, and to the available technology. Teachers, and students, need to pay attention to visuals in learning materials. Most students do not attend to the visuals unless they actually are instructed to do so. At this point, how pictures are included in the learning process is decisive on the expected impact. As an effective visualization type, infographics enable conveying complex information in a big picture by combining text and visuals. Beyond instructor-provided infographics, infographic creation enables focusing on a subject, researching in-depth and visualizing the constructed knowledge.

Published: March 2021

The intention of this chapter is to demonstrate the implementation of the innovative instructional i2Flex methodology in Elementary School, Middle School, and High School classes for young EFL, ESL, and Foreign Language learners. Within a conceptual framework consisting of the ACS educational philosophy, reference features of foreign language teaching and the terminological definition of i2Flex, the three authors will outline a detailed explanation of their methodological and educational procedures, translating the i2Flex into practice in their foreign language classes. In a common conclusion of the three study cases, the authors will critically evaluate their experiences in their classrooms and the learning outcomes. They will then give insights and recommendations on how to consolidate the mutual symbiosis between face-to-face and flexible guided student learning supported by technology, guided towards independent and inquiry based student learning, in order to create a long-term, meaningful, academic blended learning in accordance to the i2Flex methodology and practice.
Asynchronous Teaching and Learning in IB English A
Authors: Syropoulos Evangelos
Published: March 2021

This chapter focuses on the benefits of incorporating asynchronous tasks, activities, components in the teaching of IB English A: Literature Yr. 1. Taking into consideration the unique challenges of the new syllabus, the author shows how asynchronous teaching/learning may enable teachers to cover in depth many literary texts, by running concurrently F2F/synchronous and asynchronous classes. Particular emphasis is placed on how low-immediacy and low-bandwidth tools may contribute to teacher-student and student-student collaboration. The author also reflects on how the use of asynchronous components smoothened the transition to an exclusively online learning environment after the closing of the schools due to the COVID-19 pandemic.
The KINONOS Project
Authors: Pinirou Lydia
Published: March 2021

In the Fall of 2017, while a rising high school junior, the author founded a school club at the American Community Schools of Athens named ΚΟΙΝΩΝΟΣ (pronounced Kinonos), derived from the Greek word “Κοινωνία” which means “Community.” ΚΟΙΝΩΝΟΣ refers to the community of people that come together for a common cause. It connotes the importance of participation in community affairs that as citizens we must all participate in community affairs in order to improve social conditions, problem solve, and better plan so as to have a healthy, thriving community. On a larger scale, ΚΟΙΝΩΝΟΣ denotes that we are all members of a community, and while we have many differences we also have commonalities, the main commonality being that we are all human beings regardless of socio-economic status, gender, opportunity, or education. Revering this simple fact is a necessary mindset in order to develop the highest form of social interest and become conscious citizens who ‘see' society's plaguing issues and address them.

Authors: Frey Alexander F. , Seyfert Christoph , Holfelder Peter J.
Published: March 2021

The nickel base alloy IN718 was manufactured by Laser Powder Bed Fusion (LPBF) using a laser spot size of 1024 μm and a laser power of 1.3 kW at a layer thickness of 160μm. The resulting porosity, microstructure and mechanical properties are presented. Very coarse and in build direction elongated grains are stacked to form a polycrystalline material with sharp single-crystal-like texture. The appearance of ∑5 grain boundaries between coincidence side lattices is recognized. Tensile testing shows highly anisotropic mechanical properties according to the revealed texture. Increasing the hatch distance reduces the severity of the texture.

Published: March 2021

A challenge in laser powder-bed fusion is to achieve high process speed while maintaining quality level of the melting tracks. One approach to increase productivity is to distribute available laser power over several laser spots, resulting in higher melting rate. Using multiple laser spots opens up new parameter spaces in comparison to the conventional single-spot exposure. In addition to classical process parameters, e.g. total laser power and scanning speed, the distribution of power to the specific spots and the respective spatial arrangement have an impact on resulting process quality and speed. Within the scope of this research work, a physically based model is presented to define multi-spot process strategies for the generation of desired melt pool dimensions. Diffractive optical elements are used in order to adjust power or spatial arrangement of multiple laser spots. Resulting melt pool has more width and less depth compared to single-spot generated melt pools. Simulations and experiments show an optimum in applied spot distance between laser spots to obtain higher melting rates.

Published: March 2021

A scraper was attached to an unequal-diameter twin-roll caster without requiring large modifications. This caster was used as a 1000 mm diameter single roll caster equipped with a scraper, and its strip casting ability was tested. The effects of the scraper angle and load, the roll speed, and the pouring temperature of the molten metal on the scribed surface, thickness distribution and average strip thickness were investigated. The scribed surface characteristics were sound and the thickness distribution was flat when the scraper angle was 60° and the scraper load was in the range of 1 to 4 kg. When the scraper load was more than 1 kg, the thickness distribution was uneven. The average strip thickness decreased as the roll speed increased. The pouring temperature of the molten metal influenced the evenness of the solidified layer thickness. The solidified layer became even as the molten metal temperature was decreased. A strip cast with the determined optimal conditions was then cold rolled down to 1 mm to improve its surface quality.
