Published: November 2022

Over six million individuals have died as a result of the infection with
severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that causes
Covid-19. The first COVID-19 vaccines were introduced to the public in
2020 through emergency authorizations. This study aims to uncover the
fears and misconceptions behind the hesitation or refusal of taking the
COVID-19 vaccine in Syria. Methods: Through a nationwide cross-sectional
study, a convenience sample of 10006 participants who were at least 18
years old and living in Syria participated in a validated questionnaire
during the period between January and May 2022 Results: The majority of
recruited individuals were female (n= 6048; 60.4%) from the (18-24) age
group (n= 5908; 59%). We recorded 5811 (58%) participants who still
have fears and anxieties about the COVID-19 vaccine. The main concerns
about vaccines were the rapid development of vaccines (41.4%), fears of
blood clots (37.9%), the fears of common side effects (35.2%), and
allergic reactions (26.5%). Conclusion: The COVID-19 vaccine is
considered the most promising measure for controlling the spread of
infection. The success of this policy will depend on the rate of global
acceptance of the vaccine. High variability in vaccine acceptance and
high vaccine hesitancy can affect the efforts to terminate the COVID-19
pandemic. Addressing the barriers associated with the acceptance of
COVID-19 vaccination will be the cornerstone
to achieving maximum vaccination coverage. The most common reasons
behind refusing the vaccine in Syria were fear of side effects, followed
by fears, general concerns, manufacturing-related reasons, and
conspiracy belief
Konstruksjon av identitetsfortellinger i barns sosiale lek
Authors: Zachrisen Berit 
Published: November 2022

Denne studien undersøker hvordan barn konstruerer identitetsfortellinger i sosial lek. Etter inspirasjon fra YuvalDavis (2010, 2011) legges et sosiologisk perspektiv til grunn for behandling og drøfting av identitetsbegrepet. Det er prosessen med å konstruere identitetsfortellinger i leken som vektlegges. Datamaterialet består av videoobservasjoner av lekende samspill fra én barnehageavdeling (3–6 år), tatt over tre semestre. Konstruksjonen av kollektive identitetsfortellinger står fram i materialet. Sentralt i disse er barnas bygging av vi-fellesskap. Bygging av vi-fellesskap kan hovedsakelig knyttes til tre trekk ved barnas samspill: kongruens, fysisk nærhet og en lyttende og åpen kroppsholdning. De kollektive identitetsfortellingene kan imidlertid også forbindes med forskjellige former for grensedragninger. Skjult i konstruksjonen av et «vi» ligger konstruksjonen av et «dem». En annen grensedragning kan knyttes til hvilke sider ved aktørene det gis aksept for innenfor et felles «vi». Spesielt i grensedragningene ligger det noen pedagogiske utfordringer.

Construction of identity narratives in children’s social play
This study examines how children construct identity narratives in social play. After inspiration from YuvalDavis (2010, 2011), a sociological approach is taken to the issue of identity. The study emphasizes the process of constructing identity narratives (not the products). The data consists of video observations of playful interactions from one kindergarten department (3–6 years), taken over three semesters. It is childrens’ construction of collective identity narratives that is most salient in the material. Central here is the construction of ‘we-ness’. The building of ‘we-ness’ is primarily linked to three main features of children’s communication: congruence, physical proximity, and a listening and open posture. However, the collective identity narratives can also relate to different forms of demarcation. Hidden in the construction of a ‘we’ is the construction of a ‘them’ that is not included in the ‘we’.  Another demarcation can be linked to which aspects of the actors are accepted within a common ‘we’. The study highlights some educational challenges especially related to the construction of demarcations among the children. (Funded by NordForsk, 85644, and UiS.)
Effects of metal layers on chemical vapor deposition of diamond films

Published: November 2022

Abstract
Diamond is recognized as one of the most promising wide bandgap materials for advanced electronic applications. However, for many practical uses, hybrid diamond growth combining metal electrodes is often demanded. Here, we present the influence of thin metal (Ni, Ir, Au) layers on diamond growth by microwave plasma chemical vapor deposition (MWCVD) employing two different concepts. In the first concept, a flat substrate (GaN) was initially coated with a thin metal layer, then exposed to the diamond MWCVD process. In the second concept, the thin diamond film was firstly formed, then it was overcoated with the metal layer and finally, once again exposed to the diamond MWCVD. It should be mentioned that this concept allows the implementation of the metal electrode into the diamond bulk. It was confirmed that the Ni thin films (15 nm) hinder the formation of diamond crystals resulting in the formation of an amorphous carbon layer. Contrary to this finding, the Ir layer resulted in a successful overgrowth by the fully closed diamond film. However, by employing concept 2 (ie hybrid diamond/metal/diamond composite), the thin Ir layer was found to be unstable and transferred into the isolated clusters, which were overgrown by the diamond film. Using the Au/Ir (30/15 nm) bilayer system stabilized the metallization and no diamond growth was observed on the metal layer.
Comparison of methods for determining speech voicing based on tests performed on paired consonants and continuous speech
Authors: Malucha Jan , Sigmund Milan 
Published: November 2022

Abstract
Voicing is an important phonetic characteristic of speech. Each phoneme belongs to a group of either voiced or unvoiced sounds. We investigated and compared the performance of five algorithms widely used to estimate speech voicing. All algorithms were implemented in Matlab and tested on both short consonants and continuous speech. Phonetically paired consonants (voiced vs unvoiced) and parts of read speech from audio books were used in the experiments. The tuned harmonics-to-noise ratio method gave the best results in both situations, ie for consonants and continuous speech. Using this method, the overall voicing of Czech, Polish, Hungarian and English was investigated. Hungarian speech showed the highest proportion of voiced parts, approx. 75 %. In other languages, the proportion of voiced parts was around 70 %.
Voltage THD limits for three- and single-phase multilevel inverters
Authors: Rehaoulia Abir 
Published: November 2022

Abstract
This paper deals with single and three phase multilevel inverters power quality. The voltage total harmonic distortion rate is an important criterion for choosing the number of inverter levels and checking compatibility with power quality requirements. In this study, the author raises an interesting issue related to the definition of voltage THD boundaries with upper and lower limits. The problem is reformulated, and a novel and more practical approach is developed for three- and single-phase multilevel inverters. Found upper and lower voltage THD limits are sufficiently verified with most known switching algorithms like sinusoidal modulation (SM) with phase disposition (PD), space vector modulation (SVM) and selective harmonic elimination (SHE). They are also valid for cascaded (H-Bridge), neutral point clamped (NPC) and flying capacitors (FC) multilevel inverters.
Drag and Heat Transfer of Double-Disk Spiked Blunt Body at Mach 5.7
Authors: Narayana Gopalakrishna , Selvaraj Saravanan 
Published: November 2022

This study focuses on exploring the possibility of addressing aerodynamic drag and heat transfer on a blunt body by placing a modified aerospike at the nose of a high-speed vehicle. Designed spiked configurations mounted over a blunt body are termed a double spike. This study examines the overall performance of these spikes in terms of drag and heat transfer. Experiments are carried out in a shock-tunnel facility, capable of simulating the enthalpy effect at high Mach number. Drag measurements over the spiked blunt body were done using an internally mountable accelerometer balance system at a freestream Mach number of 5.7 and enthalpy of 1.1 MJ/kg. Simulations using the three-dimensional finite volume-based solver High Resolution Flow Solver on Unstructured meshes lead to the selection of double-spike configurations for experimentation. Interestingly, schlieren and simulations observed the flow phenomenon modifications by the double spike with the hemispherical cap/disk at the midsection of the spike. For a specific configuration of the midspike, this study indicates that the shear layer detached by the spike tip would interact with the midspike compared to the single-spike configurations. The results show that these double-spike configurations reduce the localized heat transfer over a blunt-body surface without appreciable change in the drag. Double-spike configurations with varying midsection spike geometry, locations, and thickness of the spike are investigated. The contributions of the spike length, cap diameter, and midspike shape on overall drag and localized heat transfer were analyzed.

Published: November 2022

On February 18th, 2021, the Mars 2020 entry system successfully delivered the Perseverance rover to the surface of Mars at Jezero Crater. The entry capsule carried a set of instrumentation installed on the heat shield and backshell, named the “Mars Entry, Descent, and Landing Instrumentation 2.” The instruments include pressure transducers, thermocouples, heat flux gauges, and radiometers to measure the aerodynamic and aerothermodynamic performance of the entry vehicle. This paper describes the trajectory and atmosphere reconstruction results based on the pressure sensor measurements. The process uses a Kalman filter approach to estimate the freestream atmospheric properties from the pressure measurements combined with a model of the pressure distribution of the heatshield and other sensor inputs, including an inertial measurement unit and other on-board navigation sensors, and several external atmospheric observations. The results indicate that the upper altitude density was up to 150% higher than nominal, which is consistent with the observed early entry guidance start time. The density below 40 km was within 12% of the preflight predictions. The reconstructed axial force coefficient was approximately 2% lower than the preflight prediction across the flight range.
Hypersonic Boundary-Layer Disturbances on a Cooled, Slender Cone at Mach 6
Authors: Paquin Laura A. , Skinner Shaun N. , Laurence Stuart J. 
Published: November 2022

This paper presents an experimental study of the effect of wall cooling on the boundary-layer structures of a sharp-nosed, 5° half-angle cone in Mach 6 flow. An experimental methodology was developed that allowed quantitative measurements of second-mode disturbance growth over a range of wall-temperature ratios from [Formula: see text] without modifying the freestream disturbance environment. The cooling system comprised probe cooling, liquid nitrogen injection, and thermal insulation. The model temperature was monitored before each run, with thermocouples mounted at the base and nosetip piece agreeing within 3.3 K. Calibrated schlieren provided global and time-resolved measurements of the boundary-layer features at a freestream unit Reynolds number of [Formula: see text]. An increase in wall-cooling level was associated with a shrinking of the boundary layer and a lowering of wavepacket structure angle at the wall. Despite some outlying results, an overall trend of increasing disturbance frequency with decreasing surface temperature was observed; additionally, cooling increased the spectral amplitude and growth rate of second-mode disturbances, pushing the point of saturation upstream.
Influence of Earthquake Parameters on the Bi-directional Behavior of Base Isolation Systems

Published: November 2022

The introduction and development of the base isolation systems, especially the friction isolator device, were done recently to improve the capacity of adaptive behavior. The efficiency of multi-phase friction pendulums comes from their complexity, which helps reduce the structural responses and enhance structures' energy dissipation under lateral loads. Nevertheless, the influence of various earthquakes' properties on the behavior of base-isolation systems subjected to bi-directional seismic loading is still unclear. Hence, further research and studies regarding the behavior and capability of these systems under bi-directional loading are still necessary before incorporating this device in real-life practical applications. Therefore, this paper is intended to investigate the bi-directional behavior of the friction isolator subjected to various ground motion records. In order to do so, different versions of the friction pendulum system are selected and compared within the study context. Generally, the study's results have shown that the behavior of the friction isolator is highly dependent on low values of the PGA/PGV ratio. Besides, pulse-like earthquakes considerably impact the response of the isolator compared to non-pulse-like ones. Doi: 10.28991/CEJ-2022-08-10-02 Full Text: PDF
DIMERIZATION OF ALUMINUM PHTHALOCYANINE CHLORIDE IN ORGANIC AND AQUA-ORGANIC MEDIUM
Authors: Klimenko I. , Astakhova T. , Timokhina E. , Lobanov A. 
Published: November 2022

Aluminum phthalocyanine chloride (AlClPc) is a photoactive macroheterocyclic compound, which, in its monomeric form, is used as a photosensitizer (PS) in photodynamic therapy and diagnostics. In this paper, its physicochemical properties were studied in organic (N, N-dimethylformamide, DMF) and aqua-organic (DMF-aqua) media. It has been shown that the hydrophobic properties of AlClPc prevent its widespread use in various pharmacological compositions due to its tendency to aggregate in aqueous solutions, which leads to the formation of non-fluorescent aggregates and a decrease in its photodynamic activity. The geometry and electronic structure of AlClPc in the monomeric and dimerized (H- and
J-aggregates) states were studied using quantum-chemical calculations with the help of the electron density functional theory (DFT) method. Different types of orientation during the dimerization of AlClPc molecules are presented: “back to back”, “head to head”, “head to back”, as well as mixed-oriented types. It has been proven that both in DMF and DMF-aqua media, the preferred orientation is “back to back”, without sacrificing the monomeric geometry of the constituent molecules in the dimer. It is shown that in an aqueous organic solvent the AlClPc molecule is easily hydrated with the formation of a coordination bond between the Al atom of the AlClPc molecule and the O atom of the aqua molecule. The bond length is 2.23 Å, and the hydration energy is 16.84 kcal/mol. Hydration promotes the formation of dimers, in which two aqua molecules play the role of "bridges" between two AlClPc molecules. In such dimer, each aqua molecule has two bonds: one coordination bond between its O atom and the Al atom of one of the AlClPc molecules and one hydrogen bond between its H atom and the N atom of another AlClPc molecule. Based on the calculated data obtained, the AlClPc dimers in the DMF medium were assigned to H-aggregates, and in the DMF-water medium, to J-aggregates, respectively.
Lessons according to Shansky: the potential of N. M. Shansky’s legacy to overcome the challenges posed to the modern Russian language teacher
Authors: Bondarenko M. A. 
Published: November 2022

The paper considers N. M. Shansky’s scientific and popular scientific writings as a resource available to a modern teacher of the Russian language. Teachers can use these materials to spark students’ interest in studying Russian, to enhance their research skills and their ability to identify patterns and discrepancies between the phenomena under consideration, including the development of project research assignments. The study analysed scientific, educational, scientific reference, and popular scientific sources. It also employed observation, search, and descriptive methods as well as comparative analysis and scientific modelling. The paper presents those tasks whose content is based on the ideas and information reflected in N. M. Shansky’s works. I propose using such tasks in studying lexicology and phraseology, word formation and spelling, in mastering the functional varieties of the Russian language, and in characterising the stylistic features of texts of different types. The paper describes a variety of techniques for working with etymological, explanatory (defining), phraseological dictionaries, and literary sources. It also includes tasks for comparing entries in dictionaries of the same type as well as scientific reference and popular scientific texts. The paper provides materials for language warmups, entertaining tasks, topics for research papers. Additionally, I show the feasibility of using groupwork and referring to Internet resources. The paper concludes by arguing for the enduring value of the ideas suggested in the scientist’s works. Moreover, I highlight the potential of these materials for developing modern students’ crucial competencies as well as achieving personal, subject, and meta-subject learning outcomes formulated in the federal state educational standards.
The life cycles of the suffix -ost’- in Russian
Authors: Zelenin A. V. 
Published: November 2022

The research summarises the general framework of N. M. Shansky’s PhD thesis which initiated a range of historical lexicological and synchronic linguistic studies. The paper provides arguments and examples showing the development of the scientist’s ideas on the lexical material of the 19th century. An example is N. M. Shansky’s concept of "semantic centres" in the process of filling in important socio-cultural lacunae. Involving a range of lexemes in structuring the concept "Social Environment" through the formation of relevant connotative components in them (kazarmennost’ – salonnost’ – kabinetnost’ – berlozhnost’ – keleinost’ / Engl. barrackness – salonness – cabinetness or officeness – denness – secrecy) provides a good illustration of the scientist’s idea. The average (relative) number of derivatives with ­ost’­ in the modern language is 3 500 – 4 000 lexemes. The paper examines the lexical and word-formation innovations that expand the field of derivational bases (foreign vocabulary, calques or loan translations, and semi-calques as well as low colloquial vocabulary). Additionally, the study analyses the mechanisms of interaction between the formal and the semantic criteria with the supremacy of the latter as it contributes to the removal of the previous morphonological limitations (derivation from relative adjectives ending in ­skiy). Deriving lexemes with the double ­ost’ suffix has become possible within the word-formation pattern ending in ­ost’: one suffix is in the derivational base, the other – in the stem of the derived word (skorostnost’, lichnostnost’ / Engl. high­speedness, personhood). The paper also outlines the chronological dissonance in the formation of adjectival nouns ending in ­skost’ in Russian abroad half a century ahead of the time they appeared in the language of the metropole. The ­skost’ pattern expands the nominative field by means of including surname derivatives (dostoevskost’, chekhovskost’, stalinskost’, khrushchevskost’, and others). The semantic-motivational stimulus is the "semantic increment" formed in relative adjectives due to the strong pragmatic connotation of particular precedent surnames. Thus, lexemes with the derivational suffix ­ost’­ in the modern language show ample opportunities for development both on the basis of intralingual potentials and as a result of fo reign language influence. The research employed critical-analytical, constructive-synthetic methods, definitional analy sis, the method of distinguishing between synchronic and diachronic word-formation, multiple motivation, the method of analysing usual and occasional words.
Facilitating the Path to Licensure and Practice: International Medical Graduates in Canada
Authors: Bartman Ilona , Touchie Claire , Topps Maureen , Boulet John R. 
Published: November 2022

ABSTRACT
Canada relies heavily on foreign-trained physicians. As a Federation, with health care being a Provincial jurisdiction, this often translates into varied processes that international medical graduates (IMGs) must undertake to obtain a Canadian medical license. Two decades ago, several government officials and representatives of many physician organizations, including regulatory bodies, met and proposed 6 recommendations to make the processes standardized, simpler, and more transparent to aid internationally trained physicians in their pursuit of Canadian medical licenses.
The Medical Council of Canada (MCC) was one of the organizations at the 2002 meeting in Calgary, Alberta. As an organization responsible for the assessment of physicians’ knowledge and skills and the issuant of the Licentiate of the MCC (LMCC), a prerequisite for Canadian medical license, the MCC was one of the institutions tasked with implementation of the recommendations.
The purpose of this manuscript is to evaluate how well the recommendations were met. To do this, we explored whether the IMGs’ journey to obtain Canadian medical licenses in 2022 is more challenging or less challenging than in 2002. The MCC’s role in helping to effect changes in the licensing process was highlighted.
‘To Make a People Out of a Mere Population’: Sovereignty and Governmentality in Hegemonic Russian Cultural Policy
Authors: Romashko Tatiana 
Published: November 2022

Abstract
The paper claims that contemporary Russian cultural policy has been determined by political transformations associated with the political project to establish sovereignty that has organized Putin’s regime since 2012. The idea behind it is traced to Putin’s 2006 intention ‘to make a people out of a mere population’. To understand that intention, and to explain the contribution of culture and cultural policy to its concretization, the paper draws on Foucault’s account of sovereignty and governmentality, and the development of the Gramscian notion of hegemony. The paper argues that Putin’s regime uses governmentality in its hegemonic project to establish sovereignty. To describe that project, and the contribution of culture and cultural policy to it, the paper presents evidence of the relation between Putin’s political actions and changes in the structure of Russian state and government, Russian culture, and the cultural policy infrastructure. The paper begins with a discussion of the draft Concept of culture introduced in 2018 and concludes with an examination of its fate in order to raise the question of the contingency of Putin’s hegemonic project.
