Authors: Кирсанов М. Н.
Published: January 2022

Предлагается схема статически определимой балочной фермы регулярного типа с криволинейным верхним поясом. Для трех видов нагрузки методом индукции по числу панелей в системе компьютерной математики Maple находится зависимость прогиба середины пролета фермы от величины нагрузки, размеров и числа панелей. Прогиб середины пролета и горизонтальный сдвиг подвижной опоры находятся в аналитической форме по формуле Максвелла - Мора. Показано, что при определенном числе панелей система становится геометрически изменяемой. Приводятся диаграмма распределения усилий по стержням конструкции и линейная асимптотика зависимости прогиба от числа панелей.

The scheme of a statically definable beam girder of a regular type with a curved upper chord is proposed. For three types of load by the induction method according to the number of panels in the Maple computer mathematics system the dependence of the deflection of the middle of the truss span on the value of the load, size and number of panels is found. The deflection of the middle of the span and the horizontal displacement of the movable support in analytical form according to the Maxwell-Mohr formula are obtained. It is shown that for a certain number of panels, the system becomes geometrically variable. A diagram of the distribution of forces over the bars of the structure and the linear asymptotics of the dependence of the deflection on the number of panels are presented.

A new Medium Access Control (MACSA) scheduling algorithm is considered to simultaneously optimize these four problems. Therefore, the geographic distribution of sensor nodes takes into account the limitations of coverage and network connectivity. Optimal sensor placement based on square grids and ON/OFF scheduling approaches based on duty cycle methods can reduce the energy consumption of sensor nodes. In addition, the MACSA algorithm provides full coverage of the monitored region and ensures optimal network connectivity. First, we design and test the MACSA analytically. Secondly, through extensive simulations, we show that MACSA significantly reduces the number of ON sensors powered, and therefore the energy consumed during data transport, by up to 30%.

Mathematical modeling of Petri is applicable to many systems. It is a promising tool for describing and studying information processing systems that are characterized as simultaneous, asynchronous, distributed, parallel, nondeterministic or stochastic. As a graphical tool, Petri nets can be used as a means of visual communication, similar to flowcharts. In addition, tokens are used in these networks to simulate the dynamic and parallel activity of systems. As a mathematical tool, Petri Nets can be used to set up equations of state, algebraic equations, and other mathematical models that control the behavior of systems. Petri nets can be used by both practitioners and theorists. In general, Petri villages provide a powerful communication environment between them: practitioners can learn from theorists how to make their models more methodical, and theorists can learn from practitioners how to make their models more realistic.

A Comparative Analysis for the Enhancement of Design of Local Cultural Mobile Applications
Authors: Ariffin Shamsul Arrieya
Published: January 2022

Culturally appropriate design guidelines could support developers in designing good mobile applications for users. Many studies in developing countries have been conducted without considering the local cultural aspects of the mobile applications for the user interface design. Therefore, this study aims to investigate the usability of mobile applications for three local cultural applications in Malaysian universities to improve the design of mobile applications. The research approach of this article emphasizes the descriptive quantitative results from heuristic evaluation between academics and students in the use of three mobile apps. According to the findings, the academics’ preferences are Jawi, Songket, and Batik, in ascending order, while the students’ preferences are Songket, Jawi and Batik in ascending order. Consequently, both groups preferred Batik as it attains higher means in the heuristic evaluation. Due to the high ranking of means for all the design principles, this study provides new insights into the prospect of four cultural guidelines for local cultural mobile applications in addition to the general usability design guidelines.
The Implication of Covid-19 on Forest in Malawi
Authors: Oranu Chizoba Obianuju , Familusi Linda Chinenyenwa , Adeosun Paul Kehinde
Published: January 2022

The rate of deforestation and degradation of forests in Malawi has been remarkably high as a result of high dependency on forests for cooking fuel, expansion of agriculture and population growth. Similarly, forests in Malawi are a source of livelihood, as well as safety nets for rural communities in times of unanticipated scarcity of food or as gap fillers during regular seasonal shortfalls of food supply. The forest sector also supports agriculture which is the backbone of the economy in various ways such as in soil erosion management, soil fertility improvement, and water flow regulation. These have made the forest sector key in economic growth and poverty alleviation in Malawi, which is among the world’s poorest countries. Hence, the forest sector in Malawi is of great importance to sustainable livelihood and development. However, the high dependence on forests particularly among rural households is prone to exacerbate deforestation and degradation of forests in the COVID-19 pandemic era. This is so because Malawi, just like in other parts of the world has experienced a decline in household income and loss of jobs as a result of the pandemic, leading to increased pressure on forests, especially among forest-dependent households. This study looked at the implication of COVID-19 on the forest sector in three ways; the demand and supply of forest products as well as forest management, by reviewing relevant literature. The review showed that the COVID-19 precautionary measures such as restriction of movement and closure of border disrupted the supply chain of forest resources, which resulted in a demand shortage. Also, the ‘work from home” measure, which keeps forest guard away from forests increasing the exploitation of forest and forest conservation training programmes as well as impedes tourism to forest reserves. Therefore, the knowledge of the implication of COVID-19 on Malawi’s forest is core in building a resilient and sustainable post-COVID-19 economy.

The Development of Arab Christian Book Printing in Lebanon and Syria in the First Half of the 18th Century
Authors: Ostash Ihor
Published: January 2022

The article deals with the history of the emergence of the Arab Renaissance in Lebanon and Syria at the turn of the 17th century and the commencement of Arab Christian book printing that became a driving force in this process. Based on the analysis of scientific, historical, and religious literature, the article reveals the figure of one of the first book printers in the Middle East, Abdallāh Zakher, who invented fonts used in the first Arab Christian books and was the founder of the first printing house in Lebanon, in the town of Chouweir, at the Monastery of St John the Baptist. The author also looks into the Ukrainian contribution to the development of Arab Christian book printing, particularly the release of two publications with support from Ivan Mazepa in Alepo in 1708, namely the titular Tetraevangelion with a foreword of Athanasius III Dabbās, Patriarch of Antioch, devoted to Ivan Mazepa, and the Gospel Book at the expense of Danylo Apostol, Myrhorod Colonel.
Keywords: Arab Renaissance Nahda, Arab Christian book printing, Abdallāh Zakher, Mazepa’s Gospel, Danylo Apostol’s titular Gospel Book.
Ukrainian Diplomacy and the EU: Going beyond Association
Authors: Nahorniak Ivan
Published: January 2022

In 2019, as a result of election processes, the political leadership of both Ukraine and the EU changed. The first diplomatic contacts of the newly elected leaders augured an ambitious agenda of bilateral relations. On his first visit to Brussels, President of Ukraine Volodymyr Zelenskyy confirmed the irreversibility of the country’s course towards European and Euro-Atlantic integration and noted the essential role of the EU in supporting the territorial integrity and sovereignty of Ukraine. In turn, the newly elected European Commission led by Ursula von Der Leyen called itself a ‘geopolitical’ Commission, which gave hope for the intensification of EU integration policy in the region and a more proactive position in the fight against Russian aggression.
This article is an attempt to analyse the trend and results of the political dialogue between Ukraine and the EU in the period from June 2019 to April 2021. It also seeks to answer the question of what has been achieved and what agenda the current authorities in Kyiv and Brussels should promote in order to bring stability to Eastern Europe and the socioeconomic development to Ukraine, particularly in the context of renewing the Association Agreement.
The author concludes by noting that within the framework of the post-pandemic recovery and the long-term EU budget for 2021–2027, EU member states will receive €1.8 trillion in support of socioeconomic development and ‘green’ transformation. This may lead to the widening of the already significant development gap between our country and the EU, thus making Ukraine’s European integration next to impossible unless its partners provide major assistance or an unexpected economic breakthrough takes place. It is also argued that 2021 and 2022 are going to be decisive, as it is during this period that the EU is expected to promulgate its political and normative documents defining Ukraine’s place in its ‘open strategic autonomy’ and the European Green Deal.
Keywords: EU, European integration, Eastern Partnership, Association Agreement, renewal of the Agreement, European Neighbourhood Policy.

The Qur'anic text was still now and will remain as an inspiration to all the studies that are based on. Because it carries open connotations appropriate for all ages due to its interactive energy that it drew through the relationship between the Creator and the creature.
This relationship was drawn some of its features through the orders and prohibitions are included in this text between its folds. These orders and prohibitions have come in interaction with argumenta influential dimension are desired through those accomplished commands and prohibitions as well.
From here، my study was titled “Directive verbs of speech (Imperative- Prohibition) in Surat Al-Tawbah. The research concluded multiple results:
1) The abundance of accomplishment actions (Imperative، prohibition) in Surat Al-Tawbah as absolute abundance. Where there are more than (30) places for Imperative، and the prohibition is more than ten places، and the Imperative with prohibition is more than five places. These verbs have played role directly to show the aim from the legislation، political and social provisions by linking these verbs with their impactful dimension.
2) The convergence of verbs of speech (imperative - prohibition) has contributed to various connotations by confirming the argument and proof by the effectual dimension as well as the power of the accomplishing action through the connection between the two neighboring verbs
The Crash
Authors: Cherry Brigid
Published: January 2022

The introduction sets out an overview of the series and provides background details of its production. It opens with an account of the development of Lost and its journey into production via ABC and Disney. Discussion then follows of how the series can be positioned in terms of quality television and ‘must-see-TV', creating a popular hit. This is contrasted with the ‘puzzle box’ approach to the narrative undertaken by Abrams, and this is discussed as a major component of the cult appeal of Lost. The introduction then goes on to provide an overview of audience ratings, critical reception and industry recognition. It sets out the way in which Lost stands out as a television milestone in terms of its cult appeal, and in particular its significance as a programme ideally fitted to the era of digital media, cultural convergence and transmedia storytelling.
The Freighter
Authors: Cherry Brigid
Published: January 2022

Chapter 4 discusses the wide range of themes prevalent in the science fiction genre. Lost is positioned in relation to science fiction as a reflection of historical and political concerns, and contemporary anxieties surrounding scientific advances. The first section in this chapter sets out how the storyworld of Lost encodes conspiracy, time travel, experiments with natural forces, and the end of the world, corporate technocratic capitalism, covert operations, and warmongering. This section continues with an analysis of the science versus military narrative opposition familiar from classic science fiction, counterpointing this with the dominant opposition in the Lost narrative of the antinomy of science and faith, and an analysis of Locke in particular as the man of faith. The second part of the chapter is a case study of Faraday as an embodiment of the scientific key to solving the unique physical properties of the island, and how he anchors the narrative in terms of science and the time travel genre.
Stepping to His Own Music
Authors: Blec Yannick
Published: January 2022

From his first book on, William Melvin Kelley showed his nonconformism to given norms—a position he retained even when he joined the ranks of Black Arts movement artists. Relying not only on the concepts of the Black aesthetic and self-determination that the BAM is too often abridged to, the influences of more Eurocentric forms such as the novel and the modern and postmodern paradigms can also be found in his narratives. This chapter aims to show how Kelley tackled the various goals of the BAM and how he often rejected some of its main arguments; to demonstrate how he redefined Black identity by showing the plurality of individuals in the community and their singular identities; and to try to determine how he contemplated the diverse points of view that can be taken concerning African American culture as opposed to, or mingled with, Euro-American culture.

We present the localization and host galaxies of one repeating and two apparently nonrepeating fast radio bursts (FRBs). FRB 20180301A was detected and localized with the Karl G. Jansky Very Large Array to a star-forming galaxy at z = 0.3304. FRB20191228A and FRB20200906A were detected and localized by the Australian Square Kilometre Array Pathfinder to host galaxies at z = 0.2430 and z = 0.3688, respectively. We combine these with 13 other well-localized FRBs in the literature, and analyze the host galaxy properties. We find no significant differences in the host properties of repeating and apparently nonrepeating FRBs. FRB hosts are moderately star forming, with masses slightly offset from the star-forming main sequence. Star formation and low-ionization nuclear emission-line region emission are major sources of ionization in FRB host galaxies, with the former dominant in repeating FRB hosts. FRB hosts do not track stellar mass and star formation as seen in field galaxies (more than 95% confidence). FRBs are rare in massive red galaxies, suggesting that progenitor formation channels are not solely dominated by delayed channels which lag star formation by gigayears. The global properties of FRB hosts are indistinguishable from core-collapse supernovae and short gamma-ray bursts hosts, and the spatial offset (from galaxy centers) of FRBs is mostly inconsistent with that of the Galactic neutron star population (95% confidence). The spatial offsets of FRBs (normalized to the galaxy effective radius) also differ from those of globular clusters in late- and early-type galaxies with 95% confidence.

We detect Lyα absorption from the escaping atmosphere of HD 63433c, a R = 2.67R
⊕, P = 20.5 day mini-Neptune orbiting a young (440 Myr) solar analog in the Ursa Major Moving Group. Using Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph, we measure a transit depth of 11.1 ± 1.5% in the blue wing and 8 ± 3% in the red. This signal is unlikely to be due to stellar variability, but should be confirmed by an upcoming second transit observation with HST. We do not detect Lyα absorption from the inner planet, a smaller R = 2.15R
⊕ mini-Neptune on a 7.1 day orbit. We use Keck/NIRSPEC to place an upper limit of 0.5% on helium absorption for both planets. We measure the host star’s X-ray spectrum and mid-ultraviolet flux with XMM-Newton, and model the outflow from both planets using a 3D hydrodynamic code. This model provides a reasonable match to the light curve in the blue wing of the Lyα line and the helium nondetection for planet c, although it does not explain the tentative red wing absorption or reproduce the excess absorption spectrum in detail. Its predictions of strong Lyα and helium absorption from b are ruled out by the observations. This model predicts a much shorter mass-loss timescale for planet b, suggesting that b and c are fundamentally different: while the latter still retains its hydrogen/helium envelope, the former has likely lost its primordial atmosphere.

We present observations of the dwarf galaxies GALFA Dw3 and GALFA Dw4 with the Advanced Camera for Surveys on the Hubble Space Telescope. These galaxies were initially discovered as optical counterparts to compact H i clouds in the GALFA survey. Both objects resolve into stellar populations which display old red giant branch (RGB), younger helium-burning, and massive main sequence stars. We use the tip of the RGB method to determine the distance to each galaxy, finding distances of

Mpc, respectively. With these distances we show that both galaxies are extremely isolated, with no other confirmed objects within ∼1.5 Mpc of either dwarf. GALFA Dw4 is also found to be unusually compact for a galaxy of its luminosity. GALFA Dw3 and Dw4 contain H ii regions with young star clusters and an overall irregular morphology; they show evidence of ongoing star formation through both ultraviolet and Hα observations and are therefore classified as dwarf irregulars (dIrrs). The star formation histories of these two dwarfs show distinct differences: Dw3 shows signs of a recently ceased episode of active star formation across the entire dwarf, while Dw4 shows some evidence for current star formation in spatially limited H ii regions. Compact H i sources offer a promising method for identifying isolated field dwarfs in the Local Volume, including GALFA Dw3 and Dw4, with the potential to shed light on the driving mechanisms of dwarf galaxy formation and evolution.

We report the result of a search for neutrinos in coincidence with solar flares from the GOES flare database. The search was performed on a 10.8 kton-year exposure of KamLAND collected from 2002 to 2019. This large exposure allows us to explore previously unconstrained parameter space for solar flare neutrinos. We found no statistical excess of neutrinos and established 90% confidence level upper limits of 8.4 × 107 cm−2 (3.0 × 109 cm−2) on the electron antineutrino (electron neutrino) fluence at 20 MeV normalized to the X12 flare, assuming that the neutrino fluence is proportional to the X-ray intensity.
Standardized Long Gamma-Ray Bursts as a Cosmic Distance Indicator

Published: January 2022

Gamma-ray bursts (GRBs) are the most luminous explosions in and can be detectable out to the edge of the universe. They have long been thought to be able to extend the Hubble diagram to very high redshifts. Several correlations between temporal or spectral properties and GRB luminosities have been proposed to make GRBs cosmological tools. However, those correlations cannot be properly standardized. In this paper, we select a long-GRB sample with X-ray plateau phases produced by electromagnetic dipole emissions from central newborn magnetars. A tight correlation is found between the plateau luminosity and the end time of the plateau in the X-ray afterglows out to the redshift z = 5.91. We standardize these long-GRB X-ray light curves to a universal behavior through this correlation, with a luminosity dispersion of 0.5 dex. The derived distance–redshift relation of GRBs is in agreement with the standard ΛCDM model both at low and high redshifts. The evidence for an accelerating universe from this GRB sample is 3σ, which is the highest statistical significance from GRBs to date.

In an ongoing effort to expand knowledge of the Chinese cobweb spider fauna (Theridiidae), the genus Meotipa Simon, 1894 is reviewed. Two new species are described, Meotipa pseudopicturatasp. nov., Meotipa striatasp. nov., and five known species are redescribed: Meotipa argyrodiformis (Yaginuma, 1952), Meotipa pulcherrima (Mello-Leitão, 1917), Meotipa picturata Simon, 1895, Meotipa spiniventris (O. Pickard-Cambridge, 1869), and Meotipa vesiculosa Simon, 1895.
La modélisation des systèmes urbains : une approche par la physique statistique
Authors: Barthelemy Marc
Published: January 2022

Les villes sont certainement parmi les systèmes les plus complexes construits par les humains. Elles sont constituées d'un grand nombre d’acteurs différents qui interagissent à différentes échelles, favorisant l’émergence de comportements collectifs qui invalident la modélisation naïve de ces systèmes. Heureusement, la disponibilité récente de données permet de construire une « science des villes » où la physique statistique joue un rôle important pour comprendre ces systèmes complexes.

Le « Biais Urbain » de Michael Lipton : théorie et critiques
Authors: Mien Edouard , Niedbalec Arnaud
Published: January 2022

Dans son ouvrage de 1977 intitulé Pourquoi les pauvres restent-ils pauvres : Un biais urbain dans le développement mondial , Michael Lipton développait sa théorie du « biais urbain » caractérisant les politiques publiques des pays dits du « Tiers Monde ». En privilégiant les populations des zones urbaines au détriment des zones rurales, les politiques fiscales et monétaires de ces pays s’avéreraient inefficientes. Nous questionnerons ce « biais urbain » à l’aune des développements de son auteur et des différentes critiques qui lui ont été adressées.

Since the inception of the current pandemic, COVID-19 related misinformation has played a role in defaulting control of the situation. It has become evident that the internet, social media, and other communication outlets with readily available data have contributed to the dissemination and availability of misleading information. It has perpetuated beliefs that led to vaccine avoidance, mask refusal, and utilization of medications with insignificant scientific data, ultimately contributing to increased morbidity. Undoubtedly, misinformation has become a challenge and a burden to individual health, public health, and governments globally. Our review article aims at providing an overview and summary regarding the role of media, other information outlets, and their impact on the pandemic. The goal of this article is to increase awareness of the negative impact of misinformation on the pandemic. In addition, we discuss a few recommendations that could aid in decreasing this burden, as preventing the conception and dissemination of misinformation is essential.
Influencing Factors of Accounting Practitioners’ Acceptance of Mobile Learning
Authors: Cheng Guang , Shao Yige
Published: January 2022

Due to the lack of teaching purpose and planning of mobile learning platform, fragmented learning time, and strong blindness of accounting practitioners, accounting practitioners have insufficient internal motivation to accept mobile learning. Based on the unified theory of acceptance and use of technology (UTAUT model), subject factor (absorptive capacity) and object factor (organizational commitment) of accounting practitioners to accept mobile learning were included, and influencing factors of accounting practitioners to accept mobile learning were empirically explored. The results show that overall Cronbach’s ɑ coefficient of the questionnaire is 0.794, indicating that reliability of the questionnaire is good. KMO value is 0.860, which is greater than 0.8, indicating very good data validity. Expected performance, effort performance, social impact and absorptive capacity positively affect accounting practitioners’ willingness to use mobile learning. Facilitation conditions and organizational commitments do not affect accounting practitioners’ willingness to use mobile learning. Results of single-factor analysis of variance show that interactive friendliness of mobile learning platform has a significant difference in accounting practitioners' willingness to use mobile learning. Results of this study have reference value for understanding how new educational technologies affect people in related industries to receive continuing education and to promote lifelong learning by adopting ubiquitous learning.
Les types de guidage des processus d'apprentissage avec des ressources numériques
Authors: Amadieu Franck
Published: January 2022

Dans le cadre des recherches sur la conception de ressources numériques pour l'apprentissage (par exemple, multimédia, hypertextes, animations, vidéos, documents sonores), de nombreuses études ont été menées sur l'efficacité de certains dispositifs de guidage pour accompagner l'apprenant dans son traitement des contenus et sa tâche d'apprentissage. Les ressources numériques qui se caractérisent par une grande étendue d'informations, une diversité de formats de présentation des informations, des modalités d'interaction avec les contenus, requièrent des ressources cognitives importantes pour être traitées efficacement. L'apprenant doit généralement engager des processus à différents niveaux de la tâche d'apprentissage : sélection, organisation, intégration, stratégies cognitives, métacognition. Pour répondre à ces exigences, un examen des revues de littérature et des méta-analyses sur la question des dispositifs de guidage dans les ressources numériques a été conduit. Cet examen a permis de déterminer les principes de guidage les plus efficaces selon les niveaux de processus engagés dans l'apprentissage à partir de ressources numériques. Des recommandations pédagogiques pour l'intégration du guidage dans ces apprentissages, ainsi que des perspectives de nouvelles recherches, sont discutées.
A Decolonial Curriculum Is Everything
Authors: Nkosinkulu Zingisa
Published: January 2022

This chapter seeks to map how indigenous people and their indigenous knowledge systems are the most researched and written about in the world, yet they are the least understood. The curriculum of the empire and its scientific explanation justified how indigenous knowledge systems should be approached and viewed as well as who has the authority to justify; hence, indigenous knowledge systems were justified as inferior and not worthy of the standard of European knowledge system. In this chapter, Frantz Fanon's thought will be deployed to illustrate how this division of knowledge justifies the perpetuating dehumanisation of indigenous people under the mask of modernisation and globalisation. By deploying decoloniality, Afrocentricity, and Fanonian thought, this chapter seeks to challenge this curriculum that is based on the history of the conquest of Africa that positioned Africa only as a cradle of slaves and the black bodied as created by God only for the benefit of the Europeans.
“I Will Never Look at This Movie the Same Again”
Authors: Lawrence Salika A.
Published: January 2022

This chapter describes self-study research that used qualitative methods to examine how films were incorporated into the secondary classroom. The study documents how popular culture movies were used in an urban high school history class to facilitate students' critical literacy. By viewing the film Enemy of the State, students were able to bridge their inside-of-school experiences with their outside-of-school practices. Incorporating popular culture movies into the history curriculum helped students shift their perspective of films from entertainment to sources of knowledge. Linking the film to the history curriculum helped students see how past events helped to shape contemporary life. Students were able to ask questions about broader social issues and engage in research to further explore topics raised in the film.

Authors: Omar Marwan , Gouveia Luís Borges , Al-Karaki Jamal , Mohammed Derek
Published: January 2022

Cyberspace is quickly becoming overwhelmed with ever-evolving malware that breaches all security defenses and secretly leaks confidential business data. One of the most pressing challenges faced by business organizations when they experience a cyber-attack is that, more often than not, those organizations do not have the knowledge nor readiness of how to analyze malware. The objective of this research is to present the fundamentals of malware reverse-engineering, the tools, and techniques needed to properly analyze malicious programs to determine their characteristics. Those tools and techniques will provide insights to incident response teams and digital investigation professionals. In order to stop hackers in their tracks, we need to equip cyber security professionals with the knowledge and skills necessary to detect and respond to malware attacks. Additionally, the authors discuss what ransomware is, how it infects systems, and how to prevent infection. It will also examine some different variations of ransomware, as well as explore some cases of ransomware.
