Sallai János: A rendészettudomány etablációja és akkreditációja Magyarországon című könyvéről, kiemelten a rendészetelméleti szakmai folyóiratok hatása a rendészettudomány kialakulásával foglalkozó fejezetekre
Authors: Dános Valér , Varga Anita , Szabó Csaba
Published: April 2022

Aim: The aim of the review of János Sallai’s publication entitled The Establishment and Accreditation of Law Enforcement Science in Hungary is to present in a short and concise form the domestic acceptance and accreditation of law enforcement science written from a historian’s perspective, for the readers of Belügyi Szemle.Methodology: The authors of this review have sought to use both qualitative and quantitative content analysis in preparing this review. The review’s authors use the same intertextuality approach to present the content of the book as it is found in the structure of the book. This is because the chapters and subchapters of the book itself are not independent, completely separate items, but are organically connected, intertwined in a chain.Conclusion: The author has fully succeeded in realizing his original intention. The publication presents almost entirely the historically long process, its individual stages, as a result of which law enforcement science has become an accepted, independent discipline in Hungary, and its acceptance in both academia and higher education has been achieved.Value: The scientific findings and information revealed by the author of the book and summarized in this publication can make a significant contribution to the further development of Hungarian law enforcement science, to its treatment as an independent science, and to the fact that in the future, journals dealing with law enforcement theory can play a major role in the further development of law enforcement science and its wider recognition.
Túlbizonyítás mint az igazságkeresés egy anomáliája a büntetőeljárásban
Authors: Zsiros Bettina
Published: April 2022

Aim: Concerning excessive evidence – beyond the quantity of evidence that is necessary to decide on the issue of guilt – it is a widespread opinion that it is nothing more than a deflection, an anomaly, that is detrimental to the economy of the procedure. This paper aims to present that the problem of excessive evidence is far more complicated than a merely practical issue.Methodology: I attempt to analyze the methods of seeking truth in criminal proceedings, or other words, excessive evidence as a dysfunction of fact-finding in the court stage of criminal proceedings.Findings: One part of the concluding thoughts are that excessive evidence is by no means just a secondary problem in forensics. Its roots derive from the fundamental issue of the search for truth and justice, as well as the functions of criminal proceedings since excessive evidence is originally an anomaly in the search for truth. In my view, this explains why it is not possible to get rid of it with methodological guidelines or recommendations for cost-efficient investigation and litigation. Consequently, excessive evidence must not only be seen as an unnecessary delay of criminal proceedings. It may also raise other significant guarantee concerns, thus undermining the rule of law in several directions at the same time.Value: This paper also points out the solutions that the Act XC of 2017 on Criminal Procedure ensures about the problem of excessive evidence.
Mapping the Planetary Wake in HD 163296 with Kinematics
Authors: Calcino Josh , Hilder Thomas , Price Daniel J. , Pinte Christophe , Bollati Francesco , Lodato Giuseppe , Norfolk Brodie J.
Published: April 2022

We map the planetary wake associated with the embedded protoplanet creating the CO kink in the disk of HD 163296. We show that the wake can be traced by a series of correlated perturbations in the peak velocity map. The sign change of the perturbations across the disk’s major axis confirms that the wake induces predominantly radial motion, as predicted by models of planet–disk interaction. These results provide the first direct confirmation of planet wakes generated by Lindblad resonances. Mapping the wake provides a constraint on the disk aspect ratio, which is required to measure the mass of the planet.
Using normal forms to study Oterma's transition in the Planar RTBP
Authors: Duarte Gladston , Jorba Àngel
Published: April 2022

Comet 39P/Oterma is known to make fast transitions between heliocentric orbits outside and inside the orbit of Jupiter. In this note the dynamics of Oterma is quantitatively studied via an explicit computation of high order Birkhoff normal forms at the points \begin{document}$ L_1 $\end{document} and \begin{document}$ L_2 $\end{document} of the Planar Restricted Three-Body Problem. A previous work [14] has shown the existence of heteroclinic connections between the neigbourhood of \begin{document}$ L_1 $\end{document} and \begin{document}$ L_2 $\end{document} which provide paths for this transition. Here we combine real data on the motion of Oterma with normal forms to compute the invariant objects that are responsible for this transition.
Bifurcation analysis of a food chain chemostat model with Michaelis-Menten functional response and double delays
Authors: Xu Xin , Qiu Yanhong , Chen Xingzhi , Zhang Hailan , Liang Zhiyuan , Tian Baodan
Published: April 2022

In this paper, we study a food chain chemostat model with Michaelis-Menten function response and double delays. Applying the stability theory of functional differential equations, we discuss the conditions for the stability of three equilibria, respectively. Furthermore, we analyze the sufficient conditions for the Hopf bifurcation of the system at the positive equilibrium. Finally, we present some numerical examples to verify the correctness of the theoretical analysis and give some valuable conclusions and further discussions at the end of the paper.
Some novel inequalities involving Atangana-Baleanu fractional integral operators and applications
Authors: Vivas-Cortez Miguel , Awan Muhammad Uzair , Rafique Sehrish , Javed Muhammad Zakria , Kashuri Artion
Published: April 2022

As we know, Atangana and Baleanu developed great fractional integral operators which used the generalized Mittag-Leffler function as non-local and non-singular kernel. Inspired by these integral operators, we derive in this paper two new fractional integral identities involving Atangana-Baleanu fractional integrals. Using these identities as auxiliary results, we establish new fractional counterparts of classical inequalities essentially using first and second order differentiable higher order strongly $ n $-polynomial convex functions. We also discuss several important special cases of the main results. In order to show the efficiency of our main results, we offer applications for special means and for differentiable functions of first and second order that are in absolute value bounded.

Theoretical Developments in Mathematics Education Research: English and French perspectives in contrast
Authors: Jaworski Barbara , Lerman Stephen , Robert Aline , Roditi Éric , Bloch Isabelle
Published: April 2022

This article traces the development of theoretical perspectives in the English and French mathematics education research cultures from the 1960 and 70s to the present. The main parts of the article are the separate accounts of development in the two domains. The two areas are presented separately since they are very different both in terms of what is in focus at different times and in terms of the theories originated, developed or appropriated. The place of a priori mathematical analysis (i.e. analysis of the mathematics to be taught, prior to teaching) seems a key difference, beyond the institutional and cultural differences. The final part of the paper draws attention to key areas of difference between the two domains and suggests key questions and issues in which there is common ground albeit addressed from the differing perspectives and cultures.
Theory of didactical situations as a tool to understand and develop mathematics teaching practices
Authors: Mangiante-Orsola Christine , Perrin-Glorian Marie-Jeanne , Strømskag Heidi
Published: April 2022

This article aims to discuss how the theory of didactical situations in mathematics (TDS1) can be used to answer research questions concerning regular teaching practices, production of resources for regular teaching, and teacher development. In the first part we focus on TDS and the way it may be a tool for the researcher to understand teaching practices and the way it may contribute to develop teaching practices, helping teachers identify questions useful for their practice. In the second part, we present analyses using TDS in two contexts in which researchers worked with teachers, making explicit or not the concepts they used. The third part approaches, from these two contexts, the way TDS may help the collaboration between researchers and teachers (or teacher educators), in research on teacher development, in particular in the case of producing resources helping teachers to prepare their class. The comparison of the two contexts informs on the specific contribution of TDS in understanding and developing mathematics teaching practices.
French and English theoretical perspectives in Mathematics Education Research: an overview and discussion of key issues

Published: April 2022

In this article we focus on issues related to theories in mathematics education as used in both French and English settings. As the final article in this special issue, we review the earlier articles and focus on the key ideas and issues which stand out for us. As with the other articles, we seek to address both common and contrasting perspectives, drawing on the examples which illustrate uses of theory. We end by pointing to issues of validation, scale and policy which challenge both groups and look towards facing such challenges jointly.
Impact des structures sémantiques et de l'introduction de schématisations sur les performances et les démarches de résolution de problèmes
Authors: Auquière Amélie , Demonty Isabelle , Fagnant Annick
Published: April 2022

Cette étude s’intéresse à l’impact de l’introduction de schématisations « range-tout » (Polotskaia et Consultant, 2010 ; Savard et Polotskaia, 2014) sur les démarches de résolution de problèmes mises en œuvre par des élèves de 9-10 ans. Au départ d’un pré-test, d’une micro-intervention et d’un post-test, les résultats mettent en lumière l’impact des structures sémantiques des problèmes sur les démarches spontanées des élèves (procédure-complément vs procédure-comparaison notamment, Gamo, Taabane et Sander, 2011) et sur la façon dont ils s’approprient les schématisations proposées. Les analyses qualitatives montrent que l’introduction des schématisations affecte positivement les performances des élèves lorsqu’elles s’accordent à leurs démarches spontanées, mais qu’elle s’avère contre-productive, à court terme, quand elle les oriente vers une démarche différente et moins économique.
Médiation sur la notion d’âge destinée à des élèves déficients intellectuels
Authors: Viné Vallin Valérie
Published: April 2022

Quel enseignant n’a pas eu dans sa classe un élève qui s’angoisse, parce qu’il ne maîtrise pas la notion de temps ? Cela est encore plus vrai chez des jeunes enfants ou des enfants porteurs d’un handicap cognitif. Cependant, il existe très peu de recherche dans le domaine des mathématiques ou des sciences cognitives portant sur cette population. Cependant, à l’heure de l’école inclusive, cela aurait toute sa pertinence. Aussi comment proposer une médiation qui réponde à leurs besoins ? Cette étude propose une évaluation diagnostique dans ce domaine ainsi qu’une médiation répondant aux besoins d’élèves scolarisés en ULIS (Unité Locale d’Inclusion Scolaire). Trente-six élèves présentant une déficience intellectuelle (DI) et deux cent élèves « typiques » ont participé à cette étude. Nous avons observé que la notion d’âge se construit plus lentement chez les sujets DI, avec un écart pouvant aller de 3 à 5 ans avec les élèves ordinaires. Cet écart s’est amoindri avec une médiation appropriée.
Dynamique du travail mathématique en classe entre un enseignant et des groupes d’élèves sur la simulation en probabilités : une étude de cas
Authors: Masselin Blandine
Published: April 2022

The purpose of this contribution is to characterize the work of a teacher on simulations in probability in grade 9 course in France (14-15 year-old students). In a case study, we report in particular on what is at stake in the solving of a probability task with simulations when the teacher decides to organize small group work. Methodological tools, such as the chronogram, related to the specificity of this type of work in class are defined in the article. We have used the theory of Mathematical Work Spaces (MWS) and concepts such as potential suitable MWS and actual suitable MWS have been defined to conduct our study. The analysis of the teacher's interventions in the classroom revealed a standardization of the probabilistic model produced by the teacher during the simulation. The role of the teacher and the choice of the digital artefact transformed the students' work. We matched blockages, rebounds or identified containments in the actual MWS with the potential MWS. Our research has clarified first cognitive task routes in probability on The Hare and the Tortoise game.
Analysing Textbook Treatment of Similarity in Plane Geometry
Authors: Wijayanti Dyana
Published: April 2022

This study presents a specific analysis of the treatment of the topic “similarity” by several college textbooks, in this case six Indonesian textbooks. The choice of this mathematical topic is justified by the fact that it requires in the activity of the pupils an implementation of both the geometric register and a numerical register, that of ratios and proportions. Thus, it is appropriate for the development of a general validity reference model, which will require further studies. The two points of theoretical support in the present study were the epistemology of the mathematical topic under consideration and the notion of praxeology, pertaining to the anthropological theory of the didactic. In addition to the meticulous review of textbook contents, the sketched model allowed us to evaluate the proximity of similarity treatments in a textbook and in the formal assessments of students at the end of college.
Effets du vocabulaire et de l’ambiguïté linguistique sur la compréhension des tests statistiques
Authors: El M’Hamedi Zahid
Published: April 2022

It is widely recognized, at least in the university medium, that the teaching of statistical tests is difficult for the teacher as well as for the learner. Indeed, the literature of educational research on this tool has revealed that there are various difficulties, often associated to some misconceptions, which are encountered at every age and level of expertise. The research findings show that a student cannot generally understand and describe the fundamental ideas underlying the practice of statistical tests. Instead, students generally rely on mechanical calculus, which is based much more on memorization and computation, than on reflection and interpretation. The aim of this paper is to present some factors that bring difficulties in apprehension to this practice and that must be considered in its teaching. Very specifically, we focused in this paper on the effect that the vocabulary and linguistic ambiguity factors, used in statistical tests, could have on the interpretation by our students of the notions and expressions conveyed during the teaching of this practice.
Reconocimiento de las variables visuales y unidades simbólicas significativas de las funciones cuadráticas
Authors: Guirette Rebeca , Gómez-Blancarte Ana , Valero-Pérez Ricardo
Published: April 2022

In this paper, we explore the qualitative recognition by 144 high school students of the visual variables of the graphical representation of a quadratic function and the significant symbolic units of its algebraic writing. This recognition emerges when students are asked to move from the graphical register to the algebraic register, and conversely. The results show that the association between the visual variables of the graphic register and the symbolic units of algebraic writing has not been fully recognized. It is considered that, although the students study the effects of the coefficients of a quadratic function, they tend to only associate them with translations through the axes, instead of with pertinent visual changes. This is not sufficient for a qualitative global apprehension that allows the coordination between the visual variables of the graphical representation of a quadratic function and the significant symbolic units of its algebraic representation.
Les connaissances du professeur dans une perspective basée sur leur spécialisation : MTSK

Published: April 2022

This paper shows the conceptualization of an analytical model of mathematics teacher’s specialized knowledge, which is based on the seminal work of Lee Shulman. In order to show the potential of the model, it is used here to analyze a particular case of a teacher of Spanish Secondary Education. The analysis shows the intertwining between different features of the knowledge of the teacher, reflecting the integrated nature of that knowledge, allowing, at the same time, a work of decomposition and synthesis of it. That will allow us to manage the design of teachers’ education, conducing also to a better understanding of mathematics teaching.

Hardcoding the “Smart” Factory
Authors: Ionescu Tudor B.
Published: April 2022

“Hardcoding” is the practice of starkly simplifying program logic to the end of producing software more effectively while sacrificing its versatility and generalizability. Drawing on concepts from science and technology studies and software engineering, this paper develops a case study of hardcoding for the “smart” factory—a kind of factory that leverages the newest information technologies to boost productivity, flexibility, and global competitiveness in existing manufacturing companies. The analysis of the ethnographic material collected through participant observation of a smart factory project in a large technology company suggests that hardcoding serves multiple purposes, which amount to the “specification of ignorance” in software development. In this sense, hardcodes reflect the “yet-to-be-knowns” in a software’s source code while conveying a project’s history of challenges and compromises.
Le code va changer

Reposant sur une enquête par entretiens, observations et l’exploitation d’un corpus de quarante enquêtés travaillant dans la Silicon Valley, cet article traite des stratégies adoptées par les développeurs pour faire face à l’incertitude de la programmation informatique en tant qu’activité professionnelle. Il porte sur la structuration temporelle de cette activité, l’incertitude se retrouvant à trois échelles de temps: les sessions de programmation, les projets et les carrières. Pour faire face aux aléas et impasses au cours des sessions de travail, les développeurs font appel à des renforts. À l’échelle du projet, ils s’appuient sur des médiations. Enfin, pour conjurer l’incertitude au sein d’une industrie caractérisée par la complexité et la volatilité des valeurs, ils cherchent à initier des tournants dans leur carrière professionnelle. À travers l’analyse de ces trois types de stratégies (renforts, médiations et tournants), cet article propose un cadre d’analyse temporelle du travail des développeurs.
Developing a simulation-based training curriculum in transesophageal ultrasound with the use of the endobronchial ultrasound-endoscope
Authors: Nayahangan Leizl Joy , Clementsen Paul Frost , Doubleday Alison , Riddle Janet , Annema Jouke T. , Konge Lars
Published: April 2022

There is an increasing need to focus on how best to train respiratory physicians to perform EUS with bronchoscope-guided fine-needle aspiration biopsy (EUS-B-FNA). At current, training is mostly performed in the clinical environment under expert supervision; however, the advent of simulation-based education now provides a low-risk setting for novice trainees to learn and practice basic endosonography skills from identifying and understanding normal anatomy as well as pathology, maneuvering of endoscope, interpretation of images, and mastering of sampling techniques. In this descriptive educational paper, we used a six-step approach as a framework to describe the development of a structured training program combining EUS-B-FNA with the already well-established certification training program in endobronchial ultrasound transbronchial needle aspiration. This comprehensive training curriculum includes a theoretical course to achieve foundational knowledge, followed by simulation-based training until mastery standards are met, and supervised clinical apprenticeship. All steps should end with an objective assessment to achieve certification. This systematic development will hopefully encourage endosonography leaders and educators to collaborate and implement an evidence-based comprehensive endosonography curriculum that aims to provide the trainee with the essential EUS-B competencies to ensure that lung cancer patients are diagnosed and staged correctly.

В статье рассматривается log-оптимальный портфель, т.е. портфель с конечной ожидаемой логарифмической полезностью, который максимизирует ожидаемую логарифмическую полезность терминального капитала, для произвольной cемимартингальной модели. В большинстве современных работ по этой теме существование и характеризации такого портфеля изучаются при условии NFLVR ("отсутствие бесплатного ланча с исчезающе малым риском"), в то же время имеется много финансовых моделей, в которых условие NFLVR нарушается, но которые допускают log-оптимальный портфель. Мы даем полную и явную характеризацию log-оптимального портфеля и связанного с ним оптимального дефлятора, приводим необходимые и достаточные условия их существования и подробно изучаем их двойственность вне зависимости от модели рынка. Наша характеризация устанавливает явную и прямую взаимосвязь log-оптимального и эталонного (numéraire) портфелей без замены вероятностной меры или эталона.
Likelihood ratio processes under nonstandard settings

В статье показывается свойство локальной асимптотической нормальности (LAN) для криволинейных нормальных семейств и систем одновременных уравнений. Кроме того, показано, что односторонние случайные модели ANOVA не имеют свойства локальной асимптотической нормальности. Рассматриваются два случая, когда дисперсия случайного эффекта лежит внутри и на границе пространства параметров. В первом случае логарифм отношения правдоподобия сходится к $0$. Во втором случае логарифм отношения правдоподобия имеет нетипичные предельные распределения, которые зависят от нормировок, отвечающих контигуальным гипотезам. Порядки этих нормировок, соответствующие дисперсиям случайных эффектов и возмущений, могут быть равными или больше единицы соответственно, а порядок, соответствующий общему среднему, может быть равен или больше половины. Следовательно, мы не можем использовать обычную оптимальную теорию, основанную на свойстве локальной асимптотической нормальности. Между тем с помощью классической схемы Неймана-Пирсона показано, что тест, основанный на логарифме отношения правдоподобия, асимптотически самый мощный.
Determination of risk factors associated with surgical site infection in patients undergoing preperitoneal pelvic packing for unstable pelvic fracture

Published: April 2022

Background: Several recent studies have shown that preperitoneal pelvic packing (PPP) effectively produces hemostasis in patients with unstable pelvic fractures. However, few studies have examined the rate of surgical site infections (SSIs) in patients undergoing PPP following an unstable pelvic fracture. The purpose of the present study was to evaluate factors associated with SSI in such patients.Methods: We retrospectively reviewed the medical charts of 188 patients who developed hemorrhagic shock due to pelvic fracture between April 2012 and May 2021. Forty-four patients were enrolled in this study.Results: SSI occurred in 15 of 44 patients (34.1%). The SSIs occurred more frequently in cases of repacking during the second-look surgery (0 vs. 4 [26.7%], P=0.010) and combined bladder-urethra injury (1 [3.4%] vs. 4 [26.7%], P=0.039). The incidence of SSIs was not significantly different between patients undergoing depacking within or after 48 hours (12 [41.4%] vs. 5 [33.3%], P=0.603). The mean time to diagnosis of SSI was 8.1±3.9 days from PPP. The most isolated organism was Staphylococcus epidermidis.Conclusions: Repacking and combined bladder-urethra injury are potential risk factors for SSI in patients with unstable pelvic fracture. Close observation is recommended for up to 8 days in patients with these risk factors. Further, 48 hours after PPP, removing the packed gauze on cessation of bleeding and not performing repacking can help prevent SSI. Additional analyses are necessary with a larger number of patients with the potential risk factors identified in this study.
Enhancing the adsorption function of F- by iron and zirconium doped zeolite: Characterization and parameter optimization

Published: April 2022

This study presented an original study on the F- removal by Fe and Zr doped Gismondine-dominated Zeolite. Various modified zeolites are prepared by systematically adjusting the synthesis variables, namely pH, mass ratio of zeolite to modify agent (mZeolite:m(Fe+Zr)), mass ratio of Fe to Zr (Fe:Zr) to investigate their effects on the F- adsorption. The performance of prepared Fe-Zr-Zeolite on F- removal was examined through both statistic adsorption and dynamic adsorption. Results indicated that when the modified pH was 7, the Fe:Zr ratio was 1:1 and mZeolite:m(Fe+Zr) was 1:2, the modified natural zeolites which was named Fe-Zr-Zeolite showed the best removal efficiency on F-. Fe-Zr-Zeolite could remove over 80% when the initial concentration was less than 20 mg/L and F- adsorption followed pseudo-second-order adsorption kinetic and Langmuir adsorption isotherm, indicating that F- adsorption by Fe-Zr-Zeolite was chemically dominated. Besides, Fe-Zr-Zeolite had better removal efficiency of F- under acidic conditions than that under alkaline conditions, and the competing anions, typically, Cl-, NO3- and SO42- had negligible effect on F- removal by Fe-Zr-Zeolite. The dynamic adsorption test demonstrated that in order to maintain the high removal efficiency of F-, the filling thickness of Fe-Zr-Zeolite should be at least 30 cm and the small the flow rate is, the higher the F- removal efficiency will be.
A Solar Energy Harvester for a Wireless Sensor System toward Environmental Monitoring
Authors: Mohsen Saeed
Published: April 2022

Harmful environments can cause severe health problems to individuals. Thus, this study proposes a solar-powered wireless sensor system to monitor the physical parameters of an ambient environment in real-time. This system is developed based on two sensors and a NodeMCU board that includes a microcontroller with a Wi-Fi chip. This system is built to measure the ambient temperature, relative humidity, atmospheric pressure, and ultraviolet (UV) index. The power supply of the system is a solar energy harvester, which consists of a solar cell, a DC-DC converter, and a rechargeable battery. This harvester is practically tested outdoors under direct sunlight. The proposed system experimentally consumes an average power of 40 mW over one hour, and the lifetime of this system is 123 hours in the active-sleep mode. The results demonstrate that the system can sustainably operate for monitoring the environmental data.

Diplomacia cultural: la inclusión de las lenguas originarias como parte de la política exterior peruana
Authors: Fiorani Denegri Ettore
Published: April 2022

El Perú se encuentra en un contexto donde el rol de las lenguas originarias se está repensando, tanto en el ámbito interior como en el exterior. Puesto que el Perú alberga la mayor cantidad de quechuahablantes en la región, no es novedad que las lenguas peruanas tengan una función en la política exterior peruana y, más específicamente, la diplomacia cultural. No obstante, es necesario detallar cuál es ese rol y a través de qué ejemplos concretos se puede evidenciar la inclusión de las lenguas originarias. Este texto busca presentar un análisis principalmente —pero no exclusivamente— cualitativo sobre la inclusión de las lenguas nativas en la política exterior del Perú, así como los desafíos y oportunidades pertinentes. Los resultados de esta investigación afirman que la inclusión de las lenguas originarias en la política exterior es un factor determinante para forjar la identidad internacional peruana y la diplomacia cultural, y para fortalecer la cooperación (bilateral y multilateral) cultural con países que tienen características, desafíos y oportunidades lingüísticas similares.

Training Load and Match-Play Performance in Collegiate Division I Basketball
Authors: Petway Adam
Published: April 2022

Purpose: This study examined the relationship between training load and match-play team performance in the subsequent game. Methods: Training load for a NCAA Division I Basketball team was tracked over a 3-year period; 225 practices were observed and recorded. Training load was classified as total duration of training and duration of full-court 5-versus-5 (5v5) during training. In-game performance was tracked for 92 matches during this period. Training load was organized into 48-hours prior to competition (MD-2), 24-hours prior to competition (MD-1), Total Duration, Average Duration, Totals 5v5, and Average 5v5. Performance was determined on how the team faired against the closing point spread differential (CPSD). If the team performed above the CPSD it was considered an ABOVE performance, whereas if the team performed below the CPSD it was considered BELOW. A linear mixed model was used to assess the differences between ABOVE and BELOW performances. Cohen’s d effect sizes (ES) were calculated to determine the magnitude of the differences. Results: Statistical significance was set at p ≤ 0.05. Both 5v5 MD-1 (p = 0.03; ES = -0.43) and Average 5v5 (p = 0.01; ES = -0.55) leading into matches was significantly greater for BELOW than ABOVE outcomes. Conclusion: 5v5 MD-1 and the Average 5v5 in preparation for competition had a significant impact on ensuing performances, whereas no significant difference was found in training MD-2. These findings could have implications on the sequencing of training sessions leading into competition.

Narratology and character functions of Sohni Mahiwal: An actantial analysis
Authors: Qasim Zareena , Qasim Asifa
Published: April 2022

The study analyses Sohni Mahiwal, the renowned Punjabi folktale, by applying Greimas Actantial model for structural analysis. The purpose of this study is to explore the narrative structure and discover the character functions based on the model. Folktales are considered the simplest and oldest form of stories embedded in the local cultures. They broadly refer to orally transmitted, traditional narratives that carry cultural information. The findings show that all the major actantial categories proposed by Greimas such as subject, object, sender, receiver, helper, and opponent have been depicted in the selected folktale. The analysis revealed that many characters were found involved in several actant classes simultaneously. Structural analysis of the folktale uncovered two parallel acts/episodes. The parallelism in the contents of two acts of the tale serves a didactic function at the socio-cultural level besides entertaining the readers/ listeners proving the strength of true love. As far as the function is concerned, the tale successfully validates the culturally imparted message that the individuals who transgress the social norms are destined to perish.
IMPLEMENTATION, VERIFICATION AND ASSESSMENT OF VORTEX CAPTURING CAPABILITIES OF k-kL TURBULENCE MODEL
Authors: DİKBAŞ Erdem , BARAN Özgür Uğraş
Published: April 2022

This study presents the first results of a new turbulence model implementation in our compressible finite volume CFD solver. The k - kL turbulence model is one of the newest two-equation models, and it is based on the ideas of Rotta’s two-equation model. Various research groups progressively develop the model, and it is maturing rapidly. Reports suggest that the k - kL turbulence model provides superior results compared to the other two-equation turbulence models in specific problems. The improved solutions are observed mainly for the flows with high adverse pressure gradients, the blunt-body wakes and jet interactions. We have implemented the k - kL model (with the standard designation of k-kL-MEAH2015) in our solver, and we are testing it rigorously. This paper presents our results on standard turbulence test cases: subsonic flat plate and subsonic wall-mounted bump. The results compare well with the reference study previously presented and published by model developers. The design of the k - kL model prevents excessive production of turbulence and dissipation; hence it preserves vortices significantly better than the other two-equation models. The implemented model is also tested with a transonic fin trailing vortex case to support this statement. Results show that the k-kL model yields considerably better results than the SST turbulence model in cases including vortices.
FAST AND PREDICTIVE HEAT PIPE DESIGN AND ANALYSIS TOOLBOX: H-PAT

Published: April 2022

For the assessment of the thermal performance of heat pipes, a wide range of modeling is available in the literature, ranging from simple capillary limit analyses to comprehensive 3D models. While simplistic models may result in less accurate predictions of heat transfer and operating temperatures, comprehensive models may be computationally expensive. In this study, a universal computational framework is developed for a fast but sufficiently accurate modeling of traditional heat pipes, and an analysis tool based on this framework, named Heat Pipe Analysis Toolbox, in short H-PAT is presented. As a diagnostic tool, H-PAT can predict the fluid flow and heat transfer from a heat pipe under varying heat inputs up to the onset of dryout. During the initial estimation of phase change rates, the solutions of particular thin film phase change models are avoided by specifying an appropriate pattern for the mass flow rate of the liquid along the heat pipe rather than using finite element/volume based methods for the computational domain. With the help of a modular structure, H-PAT can simulate heat pipes with different wick structures as long as an expression for the average liquid velocity and corresponding pressure drop can be introduced. H-PAT is also capable of analyzing heat pipes with variable cross-sections, favorable/unfavorable gravity conditions and utilizes temperature dependent thermo-physical properties at evaporator, condenser and adiabatic regions together with heat input sensitive vapor pressure. In addition, H-PAT performs the computation very fast which also makes it a perfect design tool for researchers and design engineers in the field of thermal management.
