Published: June 2022

The current situation demands the prevention of the spread of the virus, one of which is by wearing a mask and checking the body temperature. This paper serves as a means of detecting the body temperature by using a thermal camera and the mask with a web camera. The camera is the sensor, and a buzzer is an actuator that go off automatically. A mask detection device is a tool that detects visitors who wear masks. It works by detecting the visitor's face using a camera and Open CV or digital image processing. Then, the data will be processed and compared to the one that has been input into the program. This program is able to detect masks and provide warnings if the visitors do not wear masks in a public space. When the body temperature detector detects a visitor of the normal category, which is 36˚C - 37.5˚C, the buzzer does not go off; when the body temperature is higher than 37.5˚C, the buzzer goes off automatically. An error occurred due to the dark conditions, and from the five trials with 100 cm distance, 60% of the trials were successful. Therefore, it was concluded that the testing of the mask detector succeeded with more than 60% success when the lighting was sufficient; and the distance ranged from 100 cm. This system experiment with five experiments on each sample obtained pretty good results. To get good results, the light determination is very influential.
Intermediarios y posición de garante en el mercado único digital
Authors: Mora Gonzalez Jesús Iván
Published: June 2022

La jurisprudencia más reciente del Tribunal de Justicia de la Unión Europea ha puesto de manifiesto la necesidad de armonizar la responsabilidad del prestador de servicios de intermediación más allá de su delimitación negativa a través del puerto seguro. Para ellose propone una equiparación de laresponsabilidad del intermediario a la del tercero infractor a través del derecho de comunicación pública, en un intento de acomodar el rol del intermediario a los nuevos deberes reconocidos en el artículo 17 de la Directiva de Mercado Único Digital (2019). Frente a los problemas derivados de esta aproximación, la figura de la posición de garante vinculada a un efectivo derecho de defensa de las partespermitiría generar un deber específico en el intermediario consistente en impedir la continuidad de la infracción cometida previamente por un tercero,  ofreciendo con ello una solución alternativa de carácter más ponderada y garantista, resaltando con ello la posición clave del intermediario en la promoción de la creatividad y libertad de expresión en internet.
De nuevo sobre la cuestión prejudicial y la independencia judicial: el asunto IS (sentencia de 23 de noviembre de 2021, C-564/19)
Authors: Concellón Fernández Pilar
Published: June 2022

En su sentencia de 23 de noviembre de 2021 en el asunto IS, el Tribunal de Justicia de la Unión Europea ha vuelto a confirmar la amplitud del criterio de admisibilidad de las cuestiones prejudiciales relativas al Estado de Derecho, de forma que solo en casos absolutamente extremos, en los que sea imposible encontrar conexión alguna entre las cuestiones planteadas y el litigio principal, el TJ se declarará incompetente para responder. El Tribunal también ha recordado que la recurribilidad de los autos de planteamiento no puede afectar a la autonomía del juez nacional y que el principio de primacía veta cualquier disposición del Derecho nacional que impida la aplicación del procedimiento previsto en el artículo 267 TFUE. Además, los Estados miembros deberán asegurarse de adoptar las medidas necesarias para garantizar que la calidad de la interpretación y de las traducciones facilitadas durante un proceso penal sean adecuadas para que el sospechoso o acusado comprenda la acusación formulada contra él y para que esa interpretación pueda ser objeto de un control por parte de los órganos jurisdiccionales nacionales.
Procesos judiciales en los que interviene el elemento idioma como parte del conflicto
Authors: Mocholi Ester
Published: June 2022

El desconocimiento del idioma, es este caso, el español, juega un papel determinante en los procesos judiciales. Desde la representación errónea de los hechos, el desconocimiento de las prohibiciones, la falta de entendimiento en el diálogo judicial, la indefensión, hasta la manifestación misma de la adaptación al sistema, se convierten en elementos que unidos a la migración genera un gran número de conflictos. En este trabajo se analizan los conflictos donde la lengua se convierte en protagonista, desde un prisma jurisprudencial, especialmente atentos a las sentencias de la Comunidad de Madrid.
La labor de los Centros de Participación e Integración de Inmigrantes (CEPI) en la prevención, detección y canalización de problemas y conflictos derivados del empleo del idioma en el contexto de la inmigración en la Comunidad de Madrid.
Authors: Espaliú Berdud Carlos
Published: June 2022

el  Grupo de investigación de la Universidad Antonio de Nebrija en Seguridad, Gestión de Riesgos y Conflictos ha tratado de conocer los problemas y conflictos que se puedan derivar del empleo del idioma entre los inmigrantes y la población autóctona en la Comunidad de Madrid. En el marco de ese esfuerzo colectivo, este trabajo se dirige a profundizar en la labor de los Centros de Participación e Integración de Inmigrantes (CEPI) -que son instituciones puestas en marcha por la Comunidad de Madrid para la integración lingüística de los inmigrantes- en las tareas de prevención, detección y canalización de problemas y conflictos derivados del empleo del idioma. Se deduce de las entrevistas que hemos realizado con responsables de los CEPIs y de las respuestas a los cuestionarios que hemos recibido tanto por parte del personal de estas instituciones como de los propios inmigrantes, que el empleo del idioma español, o más bien la ausencia de conocimientos del mismo, genera importantes problemas en la vida diaria de los inmigrantes. Así, se han resaltado problemas serios en el ámbito laboral o para acceder a los servicios sanitarios, lo que ha revestido tintes dramáticos en algunos casos durante la pandemia. Al mismo tiempo, hemos podido apreciar en nuestra investigación que no hay conflictos migratorios reseñables en Madrid por motivos lingüísticos. A pesar de ello, destacamos que se aprecia frecuente litigiosidad, tanto en Madrid como en el resto de España, en cuanto a los recursos por denegación de la nacionalidad española causada por desconocimiento del idioma español por parte de los extranjeros, que es uno de los requisitos fijados por la normativa actual para conceder la nacionalidad, el nivel más alto de la integración en cualquier sociedad. En nuestra opinión, el trabajo de los CEPIs contribuye de manera destacable a evitar conflictos migratorios graves y a resolver los lógicos problemas que el desconocimiento del idioma plantea a las personas que vienen a vivir y trabajar a Madrid desde el extranjero.
Las dificultades de inserción laboral de inmigrantes en Madrid relacionadas con el desconocimiento de la lengua española
Authors: Regi Jordi
Published: June 2022

La inmigración en las ciudades constituye algo estructural y permanente, no coyuntural, como a veces se pretende.  Las ventajas de la inmigración para las ciudades son muchas y han sido repetidamente valoradas por los economistas: flexibilidad, disponibilidad, bajos salarios, etc. La Comunidad de Madrid ha logrado mantener un crecimiento económico y una estabilidad que ha atraído talento de todas partes de España, así como de fuera de sus fronteras, aunque también ha sufrido las consecuencias de la crisis económica iniciada en 2008. En este escenario, las personas inmigrantes se enfrentan globalmente a situaciones de desamparo que las muestra como un núcleo de población con una elevada vulnerabilidad y alto riesgo de exclusión. Este artículo analiza dificultades que surgen a consecuencia del desconocimiento de la lengua española en el ámbito laboral a los que se enfrentan los trabajadores migrantes. El uso de la lengua propia en el trabajo puede considerarse un activador de conflictos debido a que genera desconfianza y problemas de diversas magnitudes entre la población migrante y sus empleadores y/o clientes. El análisis de las causas y la búsqueda de soluciones a los mismos, son parte del objeto del presente artículo que pretende aportar una visión conciliadora desde el profundo análisis de la problemática existente.
Experimental comparison of the effectiveness of programs for minimizing systems of Boolean functions in the class of disjunctive normal forms
Authors: Bibilo P. N. , Loginova I. P.
Published: June 2022

Objectives.Methods, algorithms and programs for solving problems of minimizing the DNF representations of Boolean functions are widely used in the design of digital systems to reduce the complexity (crystal area) of functional combinational blocks of digital systems placed into digital VLSI.

The objective of the workis experimental comparison of domestic programs for minimizing Boolean functions in the DNF class included in the FLC-2 with two well-known foreign freely distributed programs for minimizing DNF known as Espresso IIC and ABC.

Methods.Four sets sample of input data were used to compare the programs – there are widely known examples on which the effectiveness of the Espresso IIC program was tested and two sets of industrial examples from the practice of designing the logic circuits. Algorithms and programs for parallelization of calculations when separate functions of minimizing have been developed. Software tools for the application of joint minimization programs with separate minimization of functions are proposed.

Results.The areas of preferred use and the execution time of programs for the source systems of functions (for minimization) characterized by large parameter values of dozens of arguments and functions, tens of thousands of elementary conjunctions are revealed. The efficiency of application of minimization programs for various forms of input data assignment is investigated – DNF, orthogonalized DNF, BDD (Binary Decision Diagrams) representations for systems of functions, truth tables and perfect DNF systems.

Conclusion.The experimental results show the effectiveness of parallel programs – reducing the calculation time and increasing the dimensions of solved problems of separate minimization of Boolean function systems.
On optimization of the mixed charging infrastructure of electric buses for urban routes
Authors: Rozin B. M. , Shaternik I. A.
Published: June 2022

Objectives. When transition from a fleet of diesel buses to a fleet of electric buses, it is important to optimize the charging infrastructure, which combines the slow-charging technologies at the depot overnight and fast recharging at the terminals of the routes. The purpose of the study is to create models and methods for developing the cost-effective solutions for selecting this type of charging infrastructure for a fleet of electric buses serving the city route system, taking into account a number of specific conditions. The operation of the fleet and charging infrastructure is modeled both for the depot at night and for the terminal stops in the most representative period of the day, characterized by the highest intensity of passenger traffic and maximum power consumption.

Methods. Methods of set theory, graph theory and linear approximation are used.

Results. A mathematical model has been developed for the problem of optimizing a mixed-type charging infrastructure for an electric bus fleet. The total daily cost of charging stations, degradation of electric bus batteries and consumed electricity was chosen as the objective function. The model is formulated as a mixed integer linear programming problem.

Conclusion. To solve the formulated problem, standard solvers like IBM ILOG CPLEX can be used. The solution of the problem lies in the choice of durations and schedules for charging electric buses at low-capacity charging stations in the depot at night and at high-capacity charging stations of terminal stops in a given range of peak hours.
Reducing the dynamic range of infrared images based on block-priority equalization and compression of histograms
Authors: Rudikov S. I. , Tsviatkou V. Yu. , Shkadarevich A. P.
Published: June 2022

Objectives. The problem of reducing the dynamic range of infrared images for their reproduction on display devices with a narrow dynamic range is considered. The method of local image histogram equalization based on the integral distribution function of brightness is investigated. To transform the brightness of a pixel, this method uses an approximation of the local alignment values of the nearest blocks of pixels of original image. This in-creases the local contrast of the image, but leads to high computational complexity, which is increasing while block size decreases. The aim of the work is to reduce the computational complexity of adaptive equalization and compression of infrared image histograms while reducing their dynamic range.

Methods. Image processing methods are used.

Results. To reduce the computational complexity of transforming the dynamic range of infrared images, a block-priority modification of the adaptive histogram equalization method is proposed. The modification is based on the division of the set of image blocks into two subsets of high-priority and low-priority blocks depend-ing on their brightness statistical properties. When interpolating pixel values, high-priority blocks use local alignment values, and low-priority blocks use global alignment values. As a result, the total number of alignment vectors is reduced in proportion to the ratio of subsets sizes and the computational complexity of the dynamic range transformation is reduced.

Conclusion. When changing the ratio of the number of high-priority blocks of infrared image pixels to the number of all blocks in the range of 0.25–0.75, the proposed algorithm is more efficient than global and adaptive histogram equalization algorithms.

Published: June 2022

The Bangko Sentral ng Pilipinas (BSP) subscribes to the Forecasting and Policy Analysis System (FPAS) as the framework for macroeconomic forecasting and analysis in support of monetary policy formulation. FPAS is a standard framework, adopted by many in"ation-targeting central banks, that organizes the generation, consolidation, and analysis of economic information relavant to monetary policy formulation. This paper aims to describe how macroeconomic forecasts and policy simulations are generated to support monetary policy analysis and formulation at the BSP. To this end, this article summarizes the main features of the process involved in generating the baseline forecasts, alternative scenarios, and policy simulations. We highlight the complementary roles played by the BSP’s suite of models and the expert judgement from the sector specialists as well as the importance of forecast communication in the transmission of monetary policy. Finally, we present a systematic evaluation of the forecasting performance of the BSP from 2010 to 2020 together with some of the lessons in forecasting during the COVID-19 pandemic and the recent efforts to improve the BSP’s FPAS.

Published: June 2022

Lifestyle is a critical aspect of diabetes management. We aimed to define a healthy lifestyle using objectively measured parameters obtained from a wearable activity tracker (Fitbit) in patients with type 2 diabetes. This prospective observational study included 24 patients (mean age, 46.8 years) with type 2 diabetes. Expectation–maximization clustering analysis produced two groups: A (n=9) and B (n=15). Group A had a higher daily step count, lower resting heart rate, longer sleep duration, and lower mean time differences in going to sleep and waking up than group B. A Shapley additive explanation summary analysis indicated that sleep-related factors were key elements for clustering. The mean hemoglobin A1c level was 0.3 percentage points lower at the end of follow-up in group A than in group B. Factors related to regular sleep patterns could be possible determinants of lifestyle clustering in patients with type 2 diabetes.
Human Tissue-Engineered Skeletal Muscle: A Tool for Metabolic Research
Authors: Kim Ji-Hoon , Yu Seung-Min , Son Jang Won
Published: June 2022

Skeletal muscle is now regarded as an endocrine organ based on its secretion of myokines and exerkines, which, in response to metabolic stimuli, regulate the crosstalk between the skeletal muscle and other metabolic organs in terms of systemic energy homeostasis. This conceptual basis of skeletal muscle as a metabolically active organ has provided insights into the potential role of physical inactivity and conditions altering muscle quality and quantity in the development of multiple metabolic disorders, including insulin resistance, obesity, and diabetes. Therefore, it is important to understand human muscle physiology more deeply in relation to the pathophysiology of metabolic diseases. Since monolayer cell lines or animal models used in conventional research differ from the pathophysiological features of the human body, there is increasing need for more physiologically relevant in vitro models of human skeletal muscle. Here, we introduce recent studies on in vitro models of human skeletal muscle generated from adult myogenic progenitors or pluripotent stem cells and summarize recent progress in the development of three-dimensional (3D) bioartificial muscle, which mimics the physiological complexity of native skeletal muscle tissue in terms of maturation and functionality. We then discuss the future of skeletal muscle 3D-organoid culture technology in the field of metabolic research for studying pathological mechanisms and developing personalized therapeutic strategies.
IMPACT OF COVID-19 ON LONG RUN AND SHORT RUN FINANCIAL INTEGRATION AMONG EMERGING ASIAN STOCK MARKETS
Authors: Bhardwaj Nikhil , Sharma Nishi , Mavi Anupreet Kaur
Published: June 2022

Purpose –The study aims at exposing any possible impact of COVID-19 on short-run and long-run financial integration among five emerging Asian economies viz., China, South Korea, India, Indonesia and Taiwan.
Research methodology – Daily closing indices of selected countries have been analyzed from January 2010 – September 2021. The integration among the selected economies has been examined for long-run and short-run through Johansan co-integration and Granger causality tests respectively.
Findings – The analysis revealed that coronavirus weakened integration among nations. The absence of long-run integration was observed after the onset of COVID-19. During pre-covid period, unidirectional as well as bi-directional causal relations were present, but after the outbreak of COVID-19, only South Korea and China reported short-term linkage.
Research limitations – The results are subject to the limitation of limited data and reference period. Further, daily returns of different stock markets are subject to domestic shock which has not been analyzed in the present study.
Practical implications – Since the absence of integration indicates an ample opportunity for risk minimization through international diversification of the portfolio, the results are expected to be very useful for investors, researchers and regulators.
Originality/Value – In present times, researchers are showing keen interest to know the possible impact of COVID-19 on linkages of international financial markets. However in spite of being rapidly growing economies, countries selected in the present study have not been explored much.
The present study aims to bridge this research gap.
The Streaming Instability Cannot Form Planetesimals from Millimeter-size Grains in Pressure Bumps
Authors: Carrera Daniel , Simon Jacob B.
Published: June 2022

We present evidence that it is unlikely that the streaming instability (SI) can form planetesimals from millimeter grains inside axisymmetric pressure bumps. We conducted the largest simulation of the SI so far (7 million CPU hours), consisting of a large slice of the disk with millimeter grains, a solar-like dust-to-gas ratio (Z = 0.01), and the largest pressure bump that does not cause gravitational instability (GI) in the particle layer. We used a high resolution of 1000/H to resolve as many SI unstable modes as possible. The simulation produced a long-lived particle overdensity far exceeding the SI criteria (i.e., a critical solid abundance to headwind parameter ratio Z/Π) where strong clumping would occur if these conditions were present over an extended region of the disk; yet we observed none. The likely reason is that the time it takes particles to cross the high-Z/Π region (t
cross) is shorter than the growth timescale of the SI (t
grow). We propose an added criterion for planetesimal formation by the SI—that t
cross > t
grow. We show that any bump larger than the one in this run would form planetesimals by the GI instead of the SI. Our results significantly restrict the pathways to planet formation: either protoplanetary disks regularly form grains larger than 1 mm, or planetesimals do not form by the SI in axisymmetric pressure bumps. Since bumps large enough to induce the GI are likely Rossby-wave unstable, we propose that millimeter grains may only form planetesimals in vortices.
Divergence in Mass Ratio Distributions between Low-mass and High-mass Coalescing Binary Black Holes

Published: June 2022

Coalescing binary black hole (BBH) systems are likely formed via several channels, and it is challenging to understand their formation/evolutionary processes. Some features in the mass function of the primary components (m
1), such as the distinct Gaussian-like peak located at ∼34 M
⊙, have been previously found. In this work, we investigate the possible dependence of the mass ratio (q = m
2/m
1) distribution on the primary mass. We find a Bayesian odds ratio of 18.1 in favor of divergence in the mass ratio distributions between the low- and high-mass ranges over an invariable mass ratio distribution. BBHs with m
1 ≳ 29 M
⊙ have a stronger preference of being symmetric compared to those with m
1 ≲ 29 M
⊙ at a 97.6% credible level. Additionally, we find mild evidence that BBHs with m
1 located in the Gaussian-like peak have a mass ratio distribution different from that of other BBHs. Our findings may favor some formation channels, such as chemically homogeneous evolution and dynamical assembly in globular clusters/nuclear star clusters, which are more likely to provide symmetric BBHs in the high-mass range.
An overview of radiation-induced heart disease
Authors: Ellahham Samer , Khalouf Amani , Elkhazendar Mohammed , Dababo Nour , Manla Yosef
Published: June 2022

Radiation therapy (RT) has dramatically improved cancer survival, leading to several inevitable complications. Unintentional irradiation of the heart can lead to radiation-induced heart disease (RIHD), including cardiomyopathy, pericarditis, coronary artery disease, valvular heart disease, and conduction system abnormalities. Furthermore, the development of RIHD is aggravated with the addition of chemotherapy. The screening, diagnosis, and follow-up for RIHD in patients who have undergone RT are described by the consensus guidelines from the European Association of Cardiovascular Imaging (EACVI) and the American Society of Echocardiography (ASE). There is compelling evidence that chest RT can increase the risk of heart disease. Although the prevalence and severity of RIHD are likely to be reduced with modern RT techniques, the incidence of RIHD is expected to rise in cancer survivors who have been treated with old RT regimens. However, there remains a gap between guidelines and clinical practice. Currently, therapeutic modalities followed in the treatment of RIHD are similar to the non-irradiated population. Preventive measures mainly reduce the radiation dose and radiation volume of the heart. There is no concrete evidence to endorse the preventive role of statins, angiotensin-converting enzyme inhibitors, and antioxidants. This review summarizes the current evidence of RIHD subtypes and risk factors and suggests screening regimens, diagnosis, treatment, and preventive approaches.

Published: June 2022

Purpose: To assess the feasibility of accelerated hypofractionated radiotherapy with simultaneous integrated boost (SIB) in patients with breast cancer.Materials and Methods: A total of 27 patients after breast-conserving surgery were included in this study. Patients were planned on a four-dimensional computerized tomogram, and contouring was done using RTOG guidelines. The dose was 34 Gy/10#/2 week to the breast and 40 Gy/10#/2 week to the tumor bed as SIB with volumetric modulated arc technique. The primary endpoint was grade 2 acute skin toxicity. Doses to the organs-at-risk were calculated. Toxicities and cosmesis were assessed using RTOG/LENT/SOMA and HARVARD/NSABP/RTOG grading scales, respectively. Disease-free survival (DFS) and overall survival (OS) were calculated with Kaplan-Meier curves.Results: The mean age of the patients was 42 years. Left and right breast cancers were seen in 17 (63%) and 10 (37%) patients, respectively. The mean values of ipsilateral lung V16 and contralateral lung V5 were 16.01% and 3.74%, respectively. The mean heart doses from the left and right breast were 7.25 Gy and 4.37 Gy, respectively. The mean doses to the contralateral breast, oesophagus, and Dmax to brachial plexus were 2.64 Gy, 3.69 Gy, and 26.95 Gy, respectively. The mean value of thyroid V25 was 19.69%. Grade 1 and 2 acute skin toxicities were observed in 9 (33%) and 5 (18.5%) patients, respectively. Grade 2 hyperpigmentation, edema, and induration were observed in 1 (3.7%), 2 (7.4%), and 4 (14.8%) patients, respectively. Mild breast pain and arm/shoulder discomfort were reported by 1 (3.4%) patient. The median follow-up was 51 months (range, 12 to 61 months). At four years, breast induration, edema, and fibrosis were observed in 1 (3.7%) patient. Cosmesis was excellent and good in 21 (78%) and 6 (22%) patients, respectively. Local recurrence and distant metastases occurred in 1 (3.7%) and 2 (7.4%) patients, respectively. DFS and OS at four years were 88% and 92%, respectively.Conclusion: With this radiotherapy schedule, acute and late toxicity rates were acceptable with no adverse cosmesis. Local control, DFS, and OS were good.

Les évolutions du vote catholique
Authors: Fourquet Jérôme , Sarthou-Lajus Nathalie
Published: June 2022

Le vote des catholiques lors des dernières présidentielles correspond à celui de l’ensemble de la société française, tout aussi diversifié et fragmenté. Il est néanmoins possible d’identifier un « bloc catholique » dont les comportements sont assez marqués et qui adhère de plus en plus à un discours national identitaire porté par la droite et l’extrême droite. Selon le directeur de l’Ifop, la perte d’influence de la matrice catholique en France sur la société et la culture n’est pas pour rien dans cette évolution.

L’écosystème d’affaires comme perspective d’étude de la convergence des acteurs de l’œnotourisme en Val de Loire (France)
Authors: Noblet Jean-Pierre , Poutier Elizabeth
Published: June 2022

En France, les enjeux liés à l’économie du tourisme vitivinicole sont fondamentaux, autant pour l’accroissement de la fréquentation touristique des régions viticoles, que pour la stimulation de la vente des produits vinicoles. Malgré la richesse œnotouristique de la France, beaucoup d’acteurs proposent une offre encore peu lisible sur le marché national et international. La grande hétérogénéité des facteurs clés de réussite des principaux modèles de développement à l’international (Australie, Espagne, Portugal, Chili, Canada…) ne facilite pas notre réflexion quant à l’existence d’un écosystème d’affaires pertinent et universel. Notre travail de recherche consistera donc à fournir un cadre théorique susceptible de nourrir notre réflexion (l’approche par les écosystèmes d’affaires), et d’envisager des pistes de développement propres à nos régions, et plus spécifiquement à notre terrain d’étude, le Val de Loire (France). Les conclusions restent mitigées : il n’y a pas d’écosystème d’affaires fiable en Val de Loire, car aucun leader n’émerge, et il n’y a pas de vision partagée et de préservation du label sur le long terme.
Pure TiO2/PSi and TiO2@Ag/PSi structures as controllable sensor for toxic gases
Authors: Abdullah Ahmed Z. , Haider Adawiya J. , Jabbar Allaa A.
Published: June 2022

In this research, two pellets of titanium dioxide TiO2 were prepared at room temperature. The first was pure titanium dioxide, and the other was doped with silver (2.5%). The pellets were deposited on porous silicon (PSi) with the pulsed laser deposition (PLD) technique. The results of scanning electron microscopy and energy-dispersive X-ray spectroscopy showed improvements in the surface morphologies of the TiO2/PSi and TiO2@Ag/PSi composites. The composites were then tested as CO2 gas sensors. The electrical measurements of the composites showed a decrease in the electrical resistance of the CO2 gas sensor doped with a metal. Sensitivity to CO2 increased to up to 55% in Ag-doped TiO2 film with a concentration of 2.5%, and the highest sensitivity value was obtained in the pure titanium dioxide film (26%).
On the fractional-order mathematical model of COVID-19 with the effects of multiple non-pharmaceutical interventions
Authors: Haq Ihtisham Ul , Ali Nigar , Ahmad Hijaz , Nofal Taher A.
Published: June 2022

In this article, the Caputo fractional derivative operator of different orders $ 0 < \alpha\leq1 $ is applied to formulate the fractional-order model of the COVID-19 pandemic. The existence and boundedness of the solutions of the model are investigated by using the Gronwall-Bellman inequality. Further, the uniqueness of the model solutions is established by using the fixed-point theory. The Laplace Adomian decomposition method is used to obtain an approximate solution of the nonlinear system of fractional-order differential equations of the model with a different fractional-order $ \alpha $ for every compartment in the model. Finally, graphical presentations are presented to show the effects of other fractional parameters $ \alpha $ on the obtained approximate solutions.
Change of Thinking, Molten Salt Reactor (MSR)
Authors: LEE Chang Hwa , KIM Tae-Hyeong , YOON Dalsung

A loss of coolant in a nuclear power plant using solid nuclear fuel can cause a severe nuclear accident, surpassing a design-basis accident, and may include a meltdown and subsequent steam and hydrogen explosion leading to a major release of radioactive material to the environment. A molten salt reactor (MSR), one of the six concepts for a Generation-IV non-pressurized water reactor, utilizes liquid fuel in which the coolant and nuclear fuel are integrated. The integration of the fuel and coolant is fundamentally safe from severe accidents caused by a loss of coolant. Because an MSR operates at atmospheric pressure and high temperature compared to pressurized water reactors, the reactor structure is simple and thermal efficiency is excellent. An MSR can be deployed at any scale from a small micro-reactor to a large commercial nuclear power plant. At a time when the role of nuclear power is growing dramatically more significant for achieving “2050 Carbon Neutrality”, the MSR technology draws attention due to its superior safety and efficiency as well as an expectation that can resolve the spent nuclear fuel issue. This article briefly introduces the characteristics and the R&D status of MSRs.
La topographie archéologique du faubourg de Daphné
Authors: Poccardi Grégoire
Published: June 2022

Dès le début de la mission d’exploration archéologique d’Antioche en 1932, le faubourg de Daphné a bénéficié d’une attention toute particulière qui a permis de dégager les restes de riches villas suburbaines, un théâtre, des vestiges des aqueducs et une petite église byzantine. Toutefois, si ces quelques années d’exploration ont permis de mieux appréhender la topographie des lieux, elles se sont limitées principalement à la partie septentrionale du plateau et n’ont donc pas permis de retrouver des traces du célèbre sanctuaire apollinien. Les études récentes ont complété notre connaissance du faubourg, en particulier par l’étude de photographies aériennes de l’époque du protectorat français et quelques découvertes fortuites.
The surprisingly long history of the Olympics of Antioch (AD 212-520)
Authors: Remijsen Sofie
Published: June 2022

The Olympics of Antioch were – as far as we know – the last surviving agon of antiquity and definitely the most prominent in Late Antique literature. This paper aims to counter the tendency to discuss them as separate from the imperial-age agones. The first section underlines how the Olympics of Antioch were simply an addition to a preexisting set of Antiochene contests, and how similar they were to other local Olympics. The second section presents some factors that made this ordinary agon stand out. It contains a brief discussion of the positive role that Antioch had as capital of Syria and of the diocese of the Orient on the contest’s Late Antique development. This section’s main focus is the rationale behind and the consequences of the choice of Daphne as its venue. A survey of the sporting accommodation in the city and at Daphne makes clear that, at the time of the games’ foundation, Daphne was not the obvious choice from a logistical point of view. But, as the example of the oldest Olympics could show, the road between the organizing city and the sanctuary of choice was not considered a hurdle. The lengthy procession drew the people in and created an idealized image of the city and its entire community. It created a strong link between the Olympics and the Antiochene identity, which made the festival impervious to the breakdown of the wide agonistic network of contests. The epilogue argues that the ban by Justin I in a particularly riotous period was probably meant to be temporary, but the natural disasters of the 520s made a return of the beloved festival impossible.
Analysing the Cryptocurrency Regulatory Environment of Malawi Using Pathetic Dot Theory
Authors: Makoza Frank
Published: June 2022

Cryptocurrencies are gaining popularity as a means of electronic payment across the globe. The aim of this paper is to analyse how financial regulatory environment can leverage the adoption of cryptocurrencies and enhance financial inclusion. The study used case of Malawi as an example of a developing country that was considering regulating cryptocurrencies. Using Pathetic Dot Theory to analyse secondary data, the findings showed that the country had substantial ICT infrastructure concentrated in urban areas that may support cryptocurrencies services. However, the country did not have adequate legal frameworks to regulate use of cryptocurrencies. The demand-side of payment systems e.g. the cryptocurrency market was still underdeveloped and required awareness of cryptocurrencies services to support financial inclusion. The study contributes to the understanding of cryptocurrencies regulatory environment in the context of developing countries.
Analysis of Entropy Generation in Micropolar Magneto-Nanoliquid Material with Activation Energy and Nonlinear Radiation

Published: June 2022

This study investigates entropy production analysis in the flow of micropolar nanoliquid due to its application in thermal engineering systems for the identification of the factors which causes the destruction in the available energy and consequently affects overall performance of the thermal devices. The model is built on a two-dimensional porous stretching sheet with an incompressible fluid assumption and steady with the influence of variable thermal conductivity, nonlinear thermal radiation, haphazard motion and thermo-migration tiny particles. A prescribed surface temperature is adopted as the thermal heating condition while the impact of the reaction order and activation energy are incorporated into the concentration field. The model equations are restructured to ordinary derivative system, which is computationally solved by Fehlberg Runge-Kutta technique. The results agree well with previous outcomes for limiting situations while the effects of the embedded terms are presented graphs. The analysis reveals that a rise in variable thermal conductivity, the material term and viscous dissipation leads to a rise in the irreversibility process.
A Review of Magnesium Based MMC Fabrication Techniques for Biomedical Applications
Authors: Sonia Pankaj , Jain Jinesh Kumar , Mohammed Kahtan A.
Published: June 2022

The magnesium is selected for the future implants material due to its excellent biocompatibility behavior. The biodegradable and biocompatible nature of Mg and its alloy make it prime choice for the development of bio-implants. The mechanical properties of Mg are similar to natural human bone therefore it can be used for temporary implantation for supporting a fracture bone. The rapid biodegradation of pure Mg before the healing time, raise the requirement to develop a metal matrix composites of Mg. The prominent technique of MMC fabrication is friction stir processing (FSP). The FSP is widely used for fabrication of surface composites and also used for grain structure refining and strengthening. The current article reviewed the various surface composites of Mg developed by FSP for alteration of biodegradation and mechanical properties. .

Published: June 2022

One of the ways to enhance thermal stability and reduce the flammability of polymers is the introduction of fillers with flame retardant properties. The paper studies the effect of natural zeolites of the Sakhaptinsk and Shivyrtuysk deposits on the thermal stability and flame retardancy of epoxy composites. The thermal stability of epoxy composites was characterized by thermogravimetric analysis in oxidizing (air) and inert (argon) atmospheres. The parameters of thermo-oxidative degradation and thermal degradation of the samples with a filler concentration of 0, 1, 5, and 10 wt% were studied. Flame retardancy of epoxy composites filled with zeolite was evaluated using the limiting oxygen index. The limiting oxygen index increases with increasing concentration of natural zeolites in the epoxy matrix. The study revealed some differences in the first and second stages of heating the epoxy composites depending on zeolite type and did not reveal significant difference in the thermal behavior of the epoxy composites in the third stage of the heating. Thermal stability and flame retardant properties are more dependent on the zeolite content in the epoxy matrix than zeolite type.
Role of Social Capital in Women-owned Businesses in Sri Lanka: A Relational Perspective
Authors: Surangi H. A. K. N. S.
Published: June 2022

Structural dimensions and gender comparison in social capital dominate the entrepreneurship literature; however, little research has focused on women entrepreneurs and the relational aspect of social capital. Therefore, the objective of this study is to explore the role of social capital in women-owned businesses in Sri Lanka, focusing on the relational dimension. Social constructionists focus on interaction, and narrative design is particularly appropriate for exploring experiences of female entrepreneurs. For this purpose, fifteen women were selected using the purposive sampling method, and narrative interviews and observations were used to collect data, which were analysed using thematic analysis. The findings show that these women favour strong ties, accumulating social capital through multiplex ties. Family ties support businesswomen more than the support received from friends and via professional links. Overall, the study further extends the dynamic view of the relational dimension of social capital with evidence from Sri Lankan women entrepreneurs.
