The Cuban Revolution in light of the key questions of revolution theory
Authors:   Moscow Region State University, Shults Eduard E.
Published: February 2023

The article examines the Cuban Revolution through the lens of the key issues of revolution theory. Questions of the causes of revolutions, their classification, stages, social base and ideology are still the subject of serious scientific discussions; therefore, the analysis of historical examples does not lose its relevance. The Cuban Revolution is of particular interest in the study of patterns of revolutions because it represents, at first glance, an unusual example among a number of previous revolutions and many that followed. The author insists that the Cuban Revolution is characterized not only by successful technologies of organizing and managing social protest and using radical mass forms of social protest in political struggle, which became popular in the second half of the 20th century and the beginning of the 21st century, but also by certain patterns characteristic of the phenomenon of revolutions. The algorithm of the Cuban Revolution and its social base finds similarities with other revolutions, especially the so-called “Third World revolutions” or “Eastern-type revolutions”. The author notes that, on the question of the causes of the revolution, researchers are grouped into two “camps”: (1) the reasons were economic underdevelopment and the poverty of Cubans, (2) other reasons because Cuba was an economically developed state for Latin America with a standard of living that was relatively high for the region. In addition, the key question is whether the factors chosen by researchers are the causes of the revolution or only the causes of the spillover of radical mass forms of social protest (trigger). Moreover, the author considers that the reasons given do not explain satisfactorily the reasons for the rise of social protest and its growth into radical and mass forms. At the same time, the solution of the agrarian issue included in the program of the Cuban Revolution unites it with many other revolutions, both before and after it.

Current conditions of increasing conflict and uncertainty point out the guidelines for the change of education correlated with the model of “knowledge society” and the goals of sustainable development in a digital society. These guidelines actualize the involvement of all citizens and institutions in the process of lifelong education and upbringing. These two notions as factors of national security require the readiness of future teachers and specialists in the social sphere to build constructive interaction with a wide range of participants in various realms. The transformation of professional training should be carried out considering the attitude to it of students themselves. The article conveys the results of a study of the pedagogical university students' satisfaction with the preparation for educational activities interaction under digitalization conditions. During the survey 446 third- to fifth-year students were interviewed, two groups of students were compared: future teachers (teachers of various subjects), future social sphere specialists (students majoring in social work, psychological and pedagogical education, vocational training, special (defectological) education, and management). The results of the study provided us with the structure of students' satisfaction with educational activities preparation that includes three factors: personal satisfaction, interactive satisfaction and satisfaction with theoretical and practical training. Overall, students have an average level of satisfaction with training in general, while they are relatively less satisfied with the interactive factor. The outcomes of the study established the following difference: future subject teachers are less satisfied with their preparation for interaction in the educational process than future specialists in the social sphere. The use of information technologies by students in educational activities correlates with the level of satisfaction concerning all three factors. Still, the strongest connection is revealed within interaction satisfaction. The results of the research allow us to empirically confirm the structure of the previously developed model of proactive preparation for educational activities and make relevant adjustments: (1) clarify the composition of subsystems (subject-environment, content, process); (2) update networking (expanding the range and productivity of interaction during the training period); (3) enhance the content of subsystems by including up-to-date information and communication technologies to organize students' training in the context of digitalization.
Legal reference systems: How to determine the future by ordering the past
Authors:   Russian State University of Justice, Northwestern Branch, Boldyrev Vladimir A. , Svarchevsky Konstantin G. ,   Russian State University of Justice, Northwestern Branch
Published: February 2023

The work aims to draw the attention of the scientific community to the problem of the influence of reference legal systems created and updated by commercial organizations on law enforcement, and to identify possible ways to solve this problem. The study was conducted using the method of content analysis, comparative and formal-logical methods, the method of forecasting. When studying the number of references in Russian judicial acts to the decisions of the European Court of Human Rights, a significant difference was found depending on the time, region, and judicial instances in which these acts were issued. The comparison led to a conclusion that the selection of official documents for placement in the reference legal system is subordinated to local practices of companies, and practices further influence court rulings issued in various regions and instances. The oblivion of “old” judicial acts, their gradual intentional and well-intended extraction from the data banks of reference legal systems as new practices are formed, inevitably affects the views of lawyers. The cognitive ease that controls human behavior, the ease of searching in databases for the necessary acts using navigation tools make the selection of a range of possible solutions from the reference legal system under heavy load conditions too convenient to turn to more complex algorithms for preparing solutions. The result of finding a solution for a difficult, multifactorial situation, especially if it has not previously been the object of evaluation by this law enforcement officer, is purposefully set by an employee of a commercial organization responsible for placing precedents in the legal reference system, organizing hyperlinks, extracting metadata, providing brief information about the essence of the resolved dispute for search purposes. The authors come to the conclusion that regulatory legal regulation is not able to give a positive result and, most likely, will have a negative effect - to have a negative impact on the commercial attractiveness and relevance of the arrays of information collected and offered to the public. The development of standards for the formation of databases of reference legal systems by extracting metadata from them, establishing hyperlinks without the help and control of the state, could become an element, a link of collective knowledge of reality, which makes it possible to simplify the decision-making process by the law enforcement officer. The formation of databases of reference legal systems based on the cooperation of their developers with the leading universities of the country could contribute to the identification of new, best practices and at the same time limit the offer of the consequences of judicial errors as a model, in particular, by accompanying documents with additional information (cautionary commentaries).

The article considers the conceptual and legal aspects of humanitarian expert appraisal, the current state of its procedure in relation to various objects, the possibilities for improving the legal framework for the humanitarian expert appraisal of games, toys and play facilities. The conceptual, ontological, methodological foundations of humanitarian expert appraisal as a type of social practice have began to be realized only recently. At present, we can talk about the relative formalization of the methodological aspects of the psychological component of humanitarian expert appraisal; debatable issues and disagreements are still observed. There is no clear-cut procedure for appointing humanitarian expert appraisal, the grounds for its appointment have not been defined, and the practice of taking into account its recommendations has not been formalized. To some extent, this picture is objective, since the objects of humanitarian expert appraisal are also diverse. Nevertheless, some legally determined commonality in conducting humanitarian expert examination is appropriate. The area of humanitarian expert appraisal that concerns the analysis of games and toys seems to be closest to the solution of the indicated problem. Until 2007 the possible negative impact on the child's health and emotional well-being of board, computer and other games, toys, play facilities was controlled through a mandatory socio-psychological and pedagogical examination. The latter was carried out on the basis of a temporary procedure approved by the Ministry of Education, was preliminary in nature and ensured that games and toys were tested for compliance with psychological safety criteria and contribution to the child's development. This procedure was canceled, and the new one is still not accepted. Thus, it should be stated that children in modern Russia are not protected legally from harm that can be caused to their psyche and development. The main conclusion of the article concerns the need to eliminate the existing gap in Russian legislation regarding the regulation of the procedure for the examination of games, toys and play facilities, as well as determining the subject responsible for the development of such rules. Apparently, such an examination should be voluntary, and it is important to take into account its results in the system of information labeling of computer games. It is advisable to label games not only on the basis of aspects of age recommendations, but also to use content marking that warns of the presence of scenes with certain undesirable content in the game.
Is it possible to ensure the rule of the “best” in a democracy?
Authors:   Altai State University, Konovalova Lyudmila G.
Published: February 2023

The article analyzes the advantages and disadvantages of democracy. Its various types and evaluations are considered. The main question that the author asks is whether democracy ensures the rule of the “best.” Such a formulation of the question is due to the fact that from the moment of its inception to the present, the idea of democracy has been associated with the hope for a “better” state administration, for the “best” representatives of society to come to power. At the same time, democracy is criticized for the lack of aristocracy, professionalism and efficiency of decisions made. An analysis is made of the proposals of various researchers on the introduction of legal levers to increase the level of aristocracy in a democratic government, including initiatives to introduce educational or property qualifications in elections, quotas for intellectual professions in parliament, professional representation, etc. The legal practice of some countries on the use of legal techniques to enhance the elitism of representation in parliaments (electoral colleges, partial appointment of members of the upper houses of parliaments, provision of additional votes in elections to certain categories of citizens) is considered. However, the conclusion is made about the inappropriateness of such novels; the opinion is motivated about the exceptional value of the openness of the democratic system, its ability to provide a potential opportunity for every citizen to participate in political decision-making. The subjectivity of the additional requirements for the elective body proposed for implementation is noted: they conflict with the idea of human dignity, which is the main achievement in the development of world history. It is suggested that socioprofessional representation, although it is able to increase the number of channels for interaction between the state and civil society, still carries the danger of excessive pressure from corporations on its members, and can lead to excessive classness in society. Special attention is paid to the modern interpretation of popular sovereignty as a legal phenomenon that manifests itself in the course of a complex discourse, the process of finding a compromise. In this regard, hopes are pinned on minimizing the risks of “not the best” people coming to power democratically and implementing their “not the best” policy on the system of separation of powers, on the “discourse” of these authorities. The idea of foreign authors about the possibility of democracy to “defend”, including from unreasonable restrictions on the electoral right (the concept of “militant democracy”) is supported.
Cynicism as a basic value in modern English humorous discourse
Authors:   Novosibirsk State Technical University, Bochkarev Arsentiy I.
Published: February 2023

The work is aimed at identifying and analyzing the main humorous characteristics of the axiological concept of cynicism. The relevance of the study is predetermined by the fact that cynicism is considered to be an important value of humorous discourse. This work develops an axiological approach for studying humor which consists of defining the reaction of the audience to cynicism (humorous or non-humorous, positive or negative), distinguishing value features of the axiological concept of cynicism (based on literature on cynicism, definitions in dictionaries, and analysis of data.), analyzing the language means used to express the axiological concept of cynicism, determining the conceptual opposition of the axiological concept of cynicism in a particular context, determining the archetype of the corresponding character to assess the level of possible empathy of the audience for a humorous object. The data analyzed in this article comprise recordings and scripts of more than 70 stand-up specials which are more than 4500 minutes long and more than 500 episodes of various sitcoms which are more than 12,500 minutes long. The research showed that in many cases manifestation of cynicism was accompanied by laughter and moderate applauding while in most cases cynicism caused only laughter. Cynicism is aimed at ridiculing such anti-values as insincerity, shame, stupidity, lust. The main cognitive features of the axiological concept of cynicism within the framework of humorous discourse include honesty and rudeness. In its extreme form (dark humor), cynicism can be considered as a significant lack of humanity. The research also found that the axiological concept of cynicism within the framework of humorous discourse is actualized through insulting people, describing taboo processes and violating the norms and principles of social interaction. Insulting is carried out through a humiliating assessment of actions or states of a person, a true designation of a person and a response to socially disapproved behavior. The main taboo topics are masturbation, deurination, flatulence, death, and declaring sexual intention. The main cases of violating norms and principles of social interaction include deviation from standard patterns of behavior and ridiculing cliched statements. The axiological concept of cynicism is usually expressed through obscene words, insulting words, verbs denoting corresponding processes, new metaphors, similes, irony, etc. Moreover, in modern English sitcoms some of main characters behave cynically.
Russian IT community in the context of socio-cultural modernization. Interview results. Part 1

Published: February 2023

The article presents the results of interviewing Russian IT specialists, which is part of the study of the socio-cultural characteristics of the Russian community of IT specialists. The first part examines the cultural identity of the interviewees. The authors infer that the identity of Russian specialists is determined by two main value “centers of attraction”: Russian and Western cultures. At the same time, Eastern culture does not have a significant impact on the value characteristics of specialists. Thus, the basis for the cultural identity of the respondents is Russian culture with a strong value bias towards Western culture. The specialists attributed the multiculturalism of Russian society, universality, hard work, as well as enterprise to the positive qualities of Russian culture, and conservatism, patience and inertia to the negative ones. Among the main differences between a Russian IT specialist and a foreign one mentioned in the interviews were: versatility, ability to adapt, proficiency, workaholism, stubbornness, commitment to results, high learning ability and collegiality as an ability to collective action, readiness for mutual assistance, as well as the fact that Russian specialists start working earlier and therefore gain experience faster than foreign colleagues. Collegiality, in the authors' opinion, is an exceptional quality in the context of the socio-cultural potential of the studied community because it is the ability for collective values that can be considered as a modernization value and a condition for the implementation of large social projects, and can be a factor in the consolidation of various social groups. The negative differences were: lack of specialized knowledge, the stereotype of the need for vocational education, focus on quick results, problems with the balance between work and personal life. The analysis of the attitude of community members to political life indicated the presence of a request for participation in the social life of society, accompanied by distrust of existing institutions.

Published: February 2023

The study purpose was to prove the effect of acute moderate-intensity endurance and strength exercise on increasing IL-6 levels in obese females.
Materials and methods. A total of 21 obese women aged 20-25 years were recruited from among university students and given two modes of acute exercise intervention, namely moderate-intensity endurance and strength exercise carried out for 35 minutes/session. Subjects were divided randomly into three groups, namely K1 (control group without intervention; n = 7), K2 (Acute moderate-intensity endurance exercise; n = 7), K3 (Acute moderate-intensity strength exercise; n = 7). ELISA was used to analyze serum IL-6 levels before and after exercise. The data analysis technique used the One-way ANOVA test and continued with the Tukey HSD post-hoc test with a significance level of 5%.
Results. The results of the One-way ANOVA test showed that there was a significant difference between serum IL-6 levels after exercise and delta (Δ) in the three groups (p ≤ 0.01). The results of the Tukey HSD post-hoc test showed that there was a significant difference between serum IL-6 levels after exercise and delta (Δ) at K3 with K1 (p ≤ 0.01), K3with K2 (p ≤ 0.01), while there was no significant difference in serum IL-6 levels (p ≥ 0.05) at K2 with K1.
Conclusions. Overall, our study concluded that 35 min/session of acute moderate-intensity strength exercise was effective in increasing anti-inflammatory cytokines, such as IL-6, in obese females.

Authors: Koryahin Viktor , Hrebinka Halyna
Published: February 2023

The study purpose was to determine the technical-and-tactical indicators of young basketball players aged 13-14 in the process of competitions and to develop recommendations for assessing the competitive activities of young basketball players.
Materials and methods. The study used the method of pedagogical observations during competitions with recording in a specially developed protocol the following indicators of competitive activity of young basketball players: throws to the basket in motion, two- and three-point throws, free throws, quick breakthrough, positional attack, struggle for rebounding the ball, interception of the ball, “goal assists”, technical errors, and other losses of the ball.
Results. As shown by the results of studies of such a technical indicator as throwing the ball into the basket in motion, young basketball players aged 13-14 have the highest accuracy in hitting the basket in this technique of the game – 49.1%. Moreover, the hit percentage (51.6) is higher in the first half of the game than in the second half (46.6) with a high significance level of the difference (p>0.99). A similar situation is observed when making two- and three-point shots from the distance. Studies of the effectiveness of free throws have shown that, on average, basketball players aged 13-14 make 14.1 free throws, of which 7.1 hit, which is 52.2 %. Studies have shown that the number of quick breakouts averages 8.45 per game (5.18 in the first half and 3.27 in the second half). The number of possessions of the ball in the fight for the rebound on own backboard is 14.9 times, and on the opponent's backboard – 13.36. The average number of “goal assists” per game is 4.36, ball interceptions – 8.18, technical errors – 15, and other ball losses – 9.54.
Conclusions. Studies of technical-and-tactical indicators of young basketball players during competitions have shown that their role is underestimated in the practice of training young basketball players. The training programs for basic training groups (aged 13-14) shall include in full all technical-and-tactical indicators, and especially throws in motion from under the backboard, two- and three-point shots, “goal assists”, free throws, ball losses, interceptions, block shots, struggle for rebound, indicators in a quick breakthrough and in a positional attack, the number of points conceded, etc. It should be noted that there is a higher number of technical-and-tactical indicators in the first half of the game, compared to the second half, with a high significance level of the difference between the indicators. This indicates the growing fatigue of young basketball players and the need to find ways to improve the system of training speed endurance and throwing techniques in a state of fatigue.

Authors: Hanifa Milati , Lidinillah Dindin Abdul Muiz , Mulyadiprana Ahmad
Published: February 2023

Perancangan buku komik ini dilatarbelakangi oleh kurangnya ketersediaan sumber belajar di sekolah dasar, juga kurangnya pengembangan sumber belajar. Padahal, sumber belajar sangat penting dan dapat digunakan di sekolah guna menunjang proses pembelajaran. Sumber belajar yang biasa digunakan di sekolah adalah sumber belajar yang disediakan oleh pemerintah. Sumber belajar tersebut lebih bersifat umum, sehingga materi pembelajaran yang bertujuan mengenalkan budaya daerah menjadi kurang efektif untuk disampaikan kepada siswa. Siswa kurang mendapatkan materi kebudayaan daerah Jawa Barat secara khusus. Di antara materi kebudayaan lokal Jawa Barat yang disampaikan adalah mengenai rumah adat, alat musik, dan seni tari. Hal tersebut tidak didapatkan pada buku yang disediakan oleh pemerintah. Penelitian ini bertujuan untuk memberikan inovasi pada pengembangan sumber belajar pada tema 1 “Indahnya Kebersamaan” yang didalamnya membahas mengenai keragaman budaya daerah setempat. Artikel ini disusun berdasarkan studi literatur dari berbagai referensi, baik referensi cetak maupun elektronik. Penelitian ini menghasilkan kesimpulan mengenai perancangan buku komik berbasis budaya lokal, yang kemudian dapat dikembangkan sebagai sumber belajar di kelas IV sekolah dasar.

Authors: Andrianov A.M. , Furs K.V. , Gonchar A.V. , Aslanyan L.H. , Tuzikov A.V.
Published: February 2023

A virtual screening of the molecular library of biologically active compounds was carried out to identify potential inhibitors of SARS-CoV-2 main protease (Mpro) which plays an important role in the process of virus replication. Using molecular docking and molecular dynamics, the binding energy of these compounds to the catalytic site of the enzyme was assessed, resulting in six molecules that exhibited high chemical affinity for SARS-CoV-2 Mpro. This is evidenced by the low values of the binding free energy of the ligand/Mpro complexes comparable with those predicted for the potent non-covalent SARS-CoV-2 Mpro inhibitor using the identical computational protocol. Based on the data obtained, it was concluded that the identified compounds have a good therapeutic potential for inhibiting the catalytic activity of the enzyme and form promising basic structures for the development of new effective drugs against COVID-19.
Modelling and Verifying Dynamic Access Control Policies in Workflow-Based Healthcare Systems
Authors:   Department of Computer Science and Engineering, Faculty of Engineering, University of Chittagong, Bangladesh, Uddin Faruqui Rokan
Published: February 2023

Access control system is an important component to protect patients’ information from abuse in a health care system. It is a major concern in the management, design, and development of healthcare systems. Designing access control policies for healthcare systems is complicated due to the dynamic and inherent complexity of the tasks performed by the healthcare personnel. Permissions in access control systems are usually granted on the basis of static policies. However, static policies are not enough to cope with various situations such as emergencies. Most often, the Break-the-glass mechanism is used to bypass static policies to handle emergency situations. Since healthcare systems are critical systems, where errors can be very costly in terms of lives, quality of life, and/or dollars, it is crucial to identify discrepancies between policy specifications and their intended function to implement correctly a flexible access control system. Formal verifications are necessary for exhaustive verification and validation of policy specifications to ensure that the policy specifications truly encapsulate the desires of the policy authors. We present a verifiable framework to enact a dynamic access control model by integrating the ANSI/INCTIS RBAC Reference Model in a workflow and an approach for property verifications of the access control model. Access control policies are expressed by the formal semantics of a model checker and properties are verified by the DiVinE model checker.
Aryl Diazonium Modification on Graphite Electrode in Microbial Fuel Cell: A Review

Usage of graphite electrode in a microbial fuel cell (MFC) is favored due to their electron conductivity and stability as a base material for the electrode. Also, graphite is favored as it allows the growth of biofilm, which can enhance the cell’s performance. The efficiency is reported improved through modification. Aryl diazonium modification has been reported to induce biofilm formation on the electrode faster. The modification can be done spontaneously or through electrografting of aryl diazonium salt onto the electrode surface. Control over the quantity of grafted aryl diazonium is essential. A thick layer will cause the performance of the system to drop, which may impede the electron transfer from biofilm to the electrode. Aryl diazonium is preferred as it allows a robust biofilm formation when used as a surface modification on the graphite electrode. Modification using aryl diazonium allows the electrode to be more accommodative for biofilm growth, which will increase the performance of the system. However, it does not act as a redox mediator for the system. It has been reported that power density obtained using aryl diazonium modified electrode is 250 mW.m-2, higher than unmodified graphite electrode of 125 mW.m-2. However, not all bacterial species is compatible with aryl diazonium modification. The unmodified graphite biocathode allows a higher power density compared to aryl diazonium modified biocathode. Hence, depending on the quality of aryl diazonium modification and the types of inoculum used, MFC performance can be further maximized.

The efforts on reducing the dependency on air-conditioning for indoor cooling has led to the implementation of passive cooling strategies in buildings. This paper investigates the implementation of reflective technologies in the form of reflective insulation and radiant barrier systems in a gable roof assembly. The thermal performance of reflective insulation and radiant barrier systems was investigated by using Computational Fluid Dynamics (CFD) simulation. The thermal performance of the reflective technologies was presented in terms of thermal resistivity, RSI value. The study was conducted for several roof configurations where the thickness of reflective air space, roof pitch and the roof material were varied. The results obtained from the CFD simulation was validated against empirical measurements to ensure the simulation gives high accuracy prediction. From the parametric analysis, it was found that thicker reflective air space would provide better air ventilation in the air space area which led to higher thermal resistivity. Besides that, steeper roof pitch would enhance the buoyancy effect and increases the heat exhaustion through the ridge which also results in higher thermal resistivity. In terms of roof tiles material, only small difference was observed in terms of thermal resistivity when switching the roof tiles material between clay tiles and concrete tiles. This research was able to demonstrate the use of CFD simulation in investigating thermal insulation technologies in buildings and this method should be explored further in the future.

Cities are increasingly turning into megacities due to their enlarged and intense population. There has been a global attempt by designers to spread the view that cities can be potential areas for producing loads of food required by communities and fitted for specific ecologies. A similar trend has been spread to developing countries where it is essential to provide food for local consumption, and serious attempts are made to distribute food materials to protect particular urban communities. Therefore, recent attempts of food security have aimed not only to guarantee availability but also the provision of sustainable, locally-fitted and food production that is not industrialized to sustain the potential for production. The solution seems to be Vertical Farming (VF). Producing food can be brought into cities through VF and this significant step, if taken, can make life in cities more viable. The present research aims to review the VF plays in the future of food production in high-density cities. The present research reviews the body of related literature, both online and printed publications on the issue. VF is a turning point of the millennium in urban designing but not limited to that. It further presents a new type of architecture as both a local and global remedy for the 21st crisis.

The manual operation of an ON/OFF controller that is being widely used in the air-cooled chiller of the air conditioning system is found to have resulted in a significant daily variation of electricity usage. As such, this study had aimed to investigate the effect from the application of a pre-programmed auto timer control system (ADTCS ON/OFF) on the performance of an air-cooled chiller and its main components in the Penang State Mosque. The ADTCS ON/OFF that had been developed for both the indoor and outdoor usage was installed to an existing air conditioning electrical distribution board (DB) via an external control panel, which had consisted of a selector switch with a timer operation, a power supply, an ON/OFF push button for the AHU, a lamp indicator as well as that of a digital timer (brand Honeywell HWTHC711A). Apart from demonstrating the implementation of the ADTCS ON/OFF control system as contributing to a more consistent operation time, this study had also shown the manual operation of the air-cooled chiller as contributing to an impactful loss of approximately 9.6 hours or 3182 kWh on a normal day when being compared to that of the ADTCS ON/OFF control system. Since the findings from this research had shown the use of an ADTCS ON/OFF control system in the air-cooled chiller system as providing a positive implication of the monthly electricity cost to the Penang State Mosque and the mosque institutions as a whole, this therefore suggests that a big savings of expenditure can also be achieved from the implementation of such a system.

Solid oxide fuel cell (SOFC) has significant advantages of clean and quiet operation while providing a relatively high efficiency owing to enhanced reaction kinetics at high operating temperature. The high operating temperature of SOFC, typically around 800 – 1000°C helps to enable internal reforming of hydrocarbons and negate effects of impurities in small quantities in the fuel. However, this limits the application of SOFC only to stationary applications due to the long period needed to reach this temperature range. A high temperature operation is also not ideal in terms of cost reduction and long-term stability of the cell components. Hence, lowering the operating temperature of SOFC is crucial for reduction of cost production and commercialization, which enables SOFC to have a wider range of application areas inclusive of portable and mobile ones. Building a high-performance SOFC with small volume is essential as the underlying criteria for these small-scale portable applications. Therefore, careful design and fabrication methods of SOFC operating on intermediate temperatures with high power outputs need to be considered. The intermediate temperature operation of the fuel cell not only increases the overall lifespan of cell but also allows for longer operation with a lower degradation rate compared to high temperature operation. Furthermore, a modified intermediate temperature stack design can accommodate a wider range of applications compared to the tubular and planar stack designs. This paper reviews the development of SOFC stack designs aimed at intermediate temperature operation towards achieving high performance and the benefits of each design.
