Connected sum for modular operads and Beilinson–Drinfeld algebras
Authors: Doubek Martin , Jurčo Branislav , Peksová Lada , Pulmann Ján
Published: October 2024

Modular operads relevant to string theory can be equipped with an additional structure, coming from the connected sum of surfaces. Motivated by this example, we introduce a notion of connected sum for general modular operads. We show that a connected sum induces a commutative product on the space of functions associated to the modular operad. Moreover, we combine this product with Barannikov’s non-commutative Batalin–Vilkovisky structure present on this space of functions, obtaining a Beilinson–Drinfeld algebra. Finally, we study the quantum master equation using the exponential defined using this commutative product.
On the spectrum of the Sturm–Liouville problem with arithmetically self-similar weight
Authors: Rastegaev Nikita
Published: October 2024

We consider the spectral asymptotics of the Sturm–Liouville problem with an arithmetically self-similar singular weight. In previous papers, A. A. Vladimirov and I. A. Sheĭpak, as well as the author, relied on the spectral periodicity property, which places major constraints on the self-similarity parameters of the weight. In this study, a different approach to estimation of the eigenvalue counting function is presented. As a result, a significantly wider class of self-similar measures can be considered. The obtained asymptotics are applied to the problem of small ball deviations for the Green Gaussian processes.

Authors: Dupré Mathilde , Marc Manon , Bussières Jean-François
Published: October 2024

RÉSUMÉ
Contexte : Les bras de fauteuils en clinique externe d’oncologie sont fréquemment contaminés au cyclophosphamide.
Objectif : Évaluer l’efficacité de scénarios de décontamination.
Méthodologie : Il s’agit d’une étude descriptive de type simulation de 6 scénarios de décontamination d’une surface de tissu en silicone contaminée avec 10 µg de cyclophosphamide. Les produits de décontamination testés (ammonium quaternaire, peroxyde d’hydrogène 0,5 %, détergent 0,005 % et hypochlorite de sodium 0,5 %) ont été utilisés avec des lingettes de microfibres. La contamination résiduelle a été mesurée à l’aide d’un système de chromatographie liquide ultra- performante et de spectrométrie de masse en tandem, avec des limites de détection et de quantification du cyclophosphamide identiques (0,0006 ng/cm2).
Résultats : Parmi les 59 échantillons, 3 blancs étaient négatifs, 5 ont permis la mesure du taux de récupération (93,7 ± 4,6 % [écart-type]) et 51 étaient expérimentaux. L’efficacité moyenne des agents était supérieure ou égale à 99,79 %. Quel que soit l’agent utilisé, l’efficacité était de 99,30 ± 1,20 % après un seul nettoyage (n = 18), 99,90 ± 0,15 % après 2 (n = 18) et 99,95 ± 0,06 % après 3 (n = 15).
Conclusions : Six scénarios de décontamination se sont avérés efficaces. La répétition du nettoyage a augmenté de façon marginale l’efficacité de la décontamination.

ABSTRACT
Background: The arms of chairs in outpatient oncology clinics are frequently contaminated with cyclophosphamide.Objective: To evaluate the effectiveness of decontamination scenarios.
Methods: This was a descriptive simulation-type study of 6 decontamination scenarios of a silicone fabric surface contaminated with 10 µg of cyclophosphamide. The decontamination products tested (quaternary ammonium, 0.5% hydrogen peroxide, 0.005% detergent, and sodium hypochlorite 0.5%) were applied with microfibre wipes. Residual contamination was measured using an ultra-performance liquid chromatography-tandem mass spectrometry system with identical cyclophosphamide detection and quantification limits (0.0006 ng/cm2).
Results: Among the 59 samples, 3 blanks were negative, 5 allowed measurement of the recovery rate (93.7% [standard deviation 4.6%]), and 51 were experimental. The average efficiency of the agents was greater than or equal to 99.79%. Regardless of the agent used, effectiveness was 99.30% (SD 1.20%) after 1 cleanse (n = 18), 99.90% (SD 0.15%) after 2 cleanses (n = 18), and 99.95% (SD 0.06%) after 3 cleanses (n = 15).
Conclusion: The 6 decontamination scenarios were effective. Repeated cleaning marginally increased the effectiveness of decontamination.

Walidacja odczytów rejestratora wypadkowego wykonanych za pomocą systemu Axes ADW
Authors: Krzemiński Michał , Ropelewski Bartłomiej
Published: October 2024

A comparison between readouts of crash data records taken with Axes ADW and Bosch CDR systems is presented. For a small group of readouts a reference was made by reading out the module memory in laboratory conditions, or using the Jaguar-Land Rover Tools. The comparison indicates favourable prospects as to the reliability of Axes ADW tool. The system offers interesting possibilities for vehicles otherwise not supported by any other tools and sporadic errors do not disqualify it from the use for crash reconstruction. However, the observed anomalies emphasize the need for the analysts of these data to have a sound knowledge background as the unconditional trust in the recovered information may lead to misinterpretations. Whenever possible, it is advised to employ various readout systems together with cross checking the recovered data.

Jak skutecznie dzielić się wiedzą na temat zwalczania terroryzmu? Wnioski, dobre praktyki i zalecenia NATO DEEP eAcademy
Authors: Szlachter Damian , Gawliczek Piotr
Published: October 2024

Experience in recent years, including intense technological development and the COVID-19 pandemic, has led to an increased interest in web-based training. E-learning allows learners to absorb knowledge at a pace that is tailored to their abilities and teachers to be more flexible in their delivery. The same circumstances that have created new forms of learning and working in a technologically developed society have triggered the rise of hybrid threats and given terrorists modern tools. In response to this trend the North Atlantic Alliance established, among others, NATO DEEP eAcademy – an entity from the sphere of education and training, whose task is to develop optimal solutions for implementing the assumptions of NATO Defence Education Enhancement Programme, i.e. a programme supporting the transformation of the military education systems of NATO partner countries. The director of this institution, Prof. Piotr Gawliczek, talks about what NATO DEEP eAcademy offers these countries and the Polish contribution to this project.
Ataki terrorystyczne, poważne incydenty i infrastruktura krytyczna. Spostrzeżenia z Berlina
Authors: Szlachter  , Fröhlich
Published: October 2024

Dramatic security incidents, such as terrorist attacks, generate widespread public interest. They arouse strong emotions, on the wave of which there are appeals to the authorities to counter threats more effectively, passionate demands for changes and declarations of their introduction. This usually lasts for a few months and then the topic goes quiet. In the interview, Paul Fröhlich from the Operations Division of the Berlin Police, an expert in the EU Protective Security Advisors programme, refers to a figurative term for this phenomenon - disaster dementia. He suggests ways to counter it, mentioning, among other things, the lessons learned and lessons identified by the Berlin police after the terrorist attack on the Berlin Christmas market. He emphasises the importance of being prepared for crises not only at national but also at individual level and the role of institutional and non-institutional cooperation.
The Jewish-Palestinian conflict. History and the Present
Authors: Izak Krzysztof
Published: October 2024

In this article, the author presents the causes and course of the Jewish-Palestinian conflict from the second half of the 19th century to the events of 2024. The main research problem concerns explaining the essence of this conflict and indicating the reasons why, in the author’s opinion, a two-state solution and life side by side for the two Jewish and Palestinian nations is impossible. The author has primarily used the historical method to show the chronology of the conflict with its pivotal moments. He considers that a lasting peace is currently unattainable because it is not wanted by the fanatical groups on both sides of the conflict, which adopts the religious motivation of the parties and thus becomes increasingly cruel and unpredictable. In his conclusions, the author points out, among other things, the deepening mutual hatred between Jews and Palestinians, which has fuelled the spiral of violence and made a political end to the conflict impossible and will continue to be so. This is also confirmed by the attempts made so far to resolve it with the involvement of third parties. The war currently being fought in Gaza will fade, but the conflict will continue and strengthen the radical factions on both sides, namely militant Islam (Hamas and Hezbollah) and the Jewish nationalist and ultra-orthodox right. The involvement of other actors in this war, notably Iran, Hezbollah and the Yemeni Houthi (Ansar Allah) movement, poses the danger of its escalation and the transfer of terrorist acts to Europe.

Authors: Deswal Mr. Deepak , S. Bisht Prof. Padam
Published: October 2024

Haryana, one of India's economically robust states, faces health infrastructure disparities among its districts. Among the 21 districts of the State, a few are endowed with better health facilities, while others lag behind. To comprehend and redress inequalities in Haryana's healthcare system, it's essential to analyze district-wise health infrastructure resources, including hospitals, health centers, medical institution beds, doctors, nurses, etc. This study aims to analyze health infrastructure disparities among Haryana's districts. The coefficients of variation, ratios, and development indices of eight indicators of health infrastructure are analyzed. The greatest disparities in health facility availability, as shown by coefficient of variation statistics, are in the number of hospital beds. The findings reveal that most districts have a disproportionately small number of health infrastructure indicators, such as doctors, nurses, beds, hospitals, primary health centers, community health centers, and dispensaries, relative to their population. The health infrastructure development indices vary significantly among districts. On the basis of these indices, it is found that the districts including Bhiwani and Hisar are developed while district Ambala, Panchkula, Karnal, Jhajjar, Jind, Sonipat, Mahendragarh and Rohtak also have a considerable improvement from year 2007-08 to 2015-16 in physical and human health infrastructure. Lastly, the third category of the districts are Kurukshetra, Panipat, Kaithal, Yamunanagar, Fatehabad, Sirsa, Faridabad, Gurugram, Rewari, Nuh and Palwal. which are underprivileged with regard to the development of health infrastructure and thus, looking for immediate attention with concrete plan of action from Government of Haryana.

Sustainable development is one of the most important goals of societies worldwide, where sustainable development indicators provide insight into its implementation. By analyzing the sustainable development indicators, it is possible to compare the respective territorial units, in terms of the level of sustainable development achieved. Fifteen indicators from all three components of sustainable development – economic, social and environmental, were analyzed for 18 local self-government units of Serbia. Based on the values of the analyzed indicators, a ranking of the local self-government units was performed using fuzzy logic so that comparing indicators, their values and the ranking of local self-government units would be as objective and appropriate as possible. The results show that the municipality of Gornji Milanovac was ranked the highest, followed by the municipalities of Negotin and Ub. The municipalities of Trstenik, Tutin and Preševo achieved the lowest scores.

Published: October 2024

The idea of the importance of open public spaces for urban sustainability can be traced through numerous theoretical works published in leading journals and monographs by renowned global publishers. At the same time, the practical application of this concept in urban planning and design, whether for new or redeveloped public spaces, is highly significant. Local communities, planners, and residents have recognized the ecological, social, and economic importance of urban public spaces. This paper, based on a literature review, analyzes the significance of urban public spaces as places of encounter and interaction and as key factors in fostering social cohesion and identity, inclusivity, and community accessibility. The focus is primarily on the relationships between urban public spaces as elements of the physical structure and their interaction with the social aspects of public spaces. Spatial and design aspects, as well as potential issues faced by the community, are considered, problems are identified, and solutions are proposed. By studying innovative approaches and creative solutions for designing new or transforming existing urban public spaces into sustainable and multifunctional units that can support various activities and community needs, the sustainability of urban public spaces, safety, security, and a healthy living environment are enhanced. The paper proposes solutions for creating smart urban public spaces using new technologies to improve their spatial, ecological, and socio-economic value. These and other parameters of open urban public spaces are addressed in this paper.
Gamification in Primary Education: What It Is, Benefits and How to Use It
Authors:   University of Kragujevac, Faculty of Education in Užice, Serbia, Arsović Branka
Published: October 2024

In the field of education in recent years, two topics stand out as dominant: online teaching and gamification. Gamification is increasingly detected as an important element in the development of learning methods, e-learning and digitalization. Game-based learning is an innovative form of education that incorporates educational computer games. Various forms of computer games are widely used in education. Gamification also includes software for educational games, learning aids, teaching improvement and student assessment. However, most teachers are very cautious and distrustful of exploring this concept of learning and its application in teaching. The paper focuses on the basic questions of this topic – what exactly is gamification in education, why is it such a growing trend, and how to apply it all in regular teaching, online and school classes. This article discussesthe effects and implications of gamification in primary education with the aim of providing a critical point of view on its use. Positive and negative effects are discussed, as well as various factors that influence the effectiveness of gamified learning. In addition, gamification is also scrutinized from a modern perspective, including points of consideration such as the current state of technological development.

Authors: Sayadyan Hovik Ya. , Grigoryan Arsen T. , Vardanyan Elmira A.
Published: October 2024

The article analyzes the geoecological condition of the landscape zones of Tavush Region. Anthropogenic load on natural landscapes expresses the degree of intensity of anthropogenic negative impacts in a given landscape zone. And anthropogenic impact on landscapes is expressed by the nature of land use structure. According to the concept of B. Kochurov, ecological and economic balance of the area 1–6 points of expert assessment are used to determine the degree of anthropogenic load on the area. Areas depending on the type of land use receive a corresponding score and are grouped into appropriate groups. Using B. Kochurov's methodology and applying the cartographic tools of the ArcGis, we obtained the map of the anthropogenic load of the landscape zones and calculated the surfaces of the areas with the corresponding level of load in each zone expressed as percentages. Then we carried out a spatial quantitative assessment of the anthropogenic load of the landscape zones with the absolute and relative coefficients of the selected concept and the tools of the ArcGis. As a result of the research, the forest-steppe zone was considered an area of critical tension based on ecological and economic indicators, the forest and meadow landscape zones were considered tense and conflicting, and the sub-alpine and alpine landscape zones were conditionally favorable.

ASSESSMENT OF DEMOGRAPHIC CAPACITY IN THE CONTEXT OF SPATIAL PLANNING
Authors: Harutyunyan Narek A.
Published: October 2024

The article discusses the issue of demographic capacity assessment in the spatial planning process. Demographic capacity (DC) is the maximum amount of population that can be accommodated in a given area, provided that the daily living requirements of the population are met with local resources, ensuring the ecological balance of the area. The need to calculate the DC stems from the goals and requirements of the proportionately and sustainable development of the area. Due to the complexity of the considered issue, an inventory of the factors determining the DC of the area and justification of their assessment methodology was carried out. DC is a variable quantity that can be changed in the conditions of scientific-technical, socio-economic progress, replenishment of national wealth. In spatial planning, we attach great importance to the integral magnitude of DC assessment. The minimum of the indicators calculated by various factors was accepted as the integrating indicator of the DC. In the article, demographic carrying capacity is calculated according to the following factors: ecological security, territorial opportunities, water resources and recreational resources. As a result of the analysis of private DC, the integrated DC of the studied area is accepted.

A neurocisticercose humana (NCC), resultante da infecção pelo parasita Taenia solium, é uma enfermidade negligenciada que afeta significativamente a saúde pública, especialmente em regiões endêmicas. Este estudo investiga a NCC, explorando seus sintomas diversificados, que incluem convulsões, cefaleias, alterações neurológicas e, em casos graves, hidrocefalia, comprometimento ocular e rebaixamento do nível de consciência. Destaca-se a complexidade do diagnóstico, muitas vezes prejudicado pela falta de acesso a recursos de neuroimagem, resultando em subnotificação e subestimação da prevalência real da doença. O tratamento da NCC inclui medicamentos cisticidas e a necessidade de corticoides para gerenciar reações inflamatórias decorrentes da morte do parasita. Além disso, aborda-se a negligência em relação à doença, evidenciando a falta de conscientização, diagnóstico tardio e intervenção adequada como principais fatores contribuintes para sua persistência e disseminação. Conclui-se que a abordagem eficaz da NCC requer uma resposta que inclua melhorias no acesso ao diagnóstico, tratamento acessível e educação pública sobre medidas preventivas.

The Performance of The Internal Audit Functions in Higher Education Institutions: The Auditees Perspective
Authors: Chenjerai Melania , Dubihlela Jobo , Makoza Frank , Le Roux Suzaan
Published: October 2024

State-owned universities worldwide are facing challenges that cast doubt on the effectiveness of their internal audit departments. The objective of the study was to assess the current state of internal audit functions in terms of performance in Zimbabwe's higher education institutions. The research utilised a multi-case study approach, focusing specifically on state universities in Zimbabwe. Data was collected through a survey distributed to auditees in these state-owned universities and analysed the responses using multiple regression analysis. For rigor and robustness, the quantitative data was triangulated with the qualitative analysis of the auditor general reports covering the years 2013 to 2021. The qualitative findings showed that auditees generally lacked knowledge about the performance of internal audit functions in public universities. Further, the auditor general reports revealed the malpractices in state universities in the presence of internal auditors. The study recommends raising awareness about the importance of internal audit functions within university communities through training, education and displaying the internal audit charter on the university website. The auditor general must be proactive by conducting audits of the internal audit function in the state-owned universities. The lack of awareness about the internal audit function despite over a decade of existence in the ZSUs is an indication of the low value attached to the departments.

Authors: Morukhu Doreen , Mabasa Fumani Donald , Khashane Khathutshelo
Published: October 2024

This study explores the competencies and capabilities that high-potential academics (HPAs) should possess to effectively handle academic responsibilities and ascend to leadership positions within higher education institutions. A qualitative research approach was employed, utilising an exploratory design owing to the lack of prior studies on this topic. The study sampled ten academic staff members from a higher education institution in South Africa and conducted face-to-face interviews to gather data. Thematic analysis was used to process the data, revealing the key talent management and leadership themes. The findings indicate that HPAs should possess various competencies, including ambition, analytical skills, adaptability, and effective communication skills. They should also demonstrate strong leadership qualities such as planning, decision-making, and emotional intelligence. This study identifies several constraints to developing HPAs, such as inadequate resources, lack of leadership capacity, and insufficient communication. The study recommends fostering a supportive environment, providing adequate funding, and recognising and rewarding high-potential academics to ensure their development and retention.
Zen-informed Spiritual Research Paradigm: A Buddhist Approach to Decolonizing MSR Research
Authors: Yu Tianyuan
Published: October 2024

In this article, I introduce a "Zen-informed spiritual research paradigm" rooted in an Eastern Buddhist worldview that fundamentally transcends Western mainstream functional- ism. I first propose a definition of "spiritual research" and discuss its philosophical and methodological implications.
I then elaborate on the features of a Zen-informed spiritual research paradigm concerning ontology, epistemology, axiology, and methodology. Furthermore, I use a field study to demonstrate the application of Zen methodologies in research design, data sampling, data collection, data analysis,
theorizing, and report writing. Finally, I propose six evaluation criteria for spiritual research along with applicable methodological strategies to meet each criterion. This research is pioneering in decolonizing MSR research paradigms through Zen-informed approaches in response to the urgent
call for a paradigmatic shift to enable global consciousness.

El Salvador is a country with high seismic demand, so the design and construction processes of buildings today areaimed at reducing the vulnerability caused by earthquakes, as part of the philosophy of damage mitigation and correct structural performance, there are Advances in detailing and construction techniques, so the use of deformation. energy dissipation systems is a safe way to prevent damage at a reasonable economic cost compared to the use of other more complex and sophisticated technologies. In El Salvador, the implementation of the TADAS (Triangular plate Added Damping And Stiffness) energy dissipation system has been implemented in a pioneering way and on a small scale, in the case of a two-story building, structured with Steel frames with ordinary detailing. The first level corresponds to parking, so the TADAS devices have only been installed in a longitudinal direction, while the second level corresponds to various uses of meeting people in meeting rooms and office work, so architectural issue the existence of windows with a view not interrupted by structural elements turned out to be a condition for not installing TADAS on that level. The final result meets the requirements of the ASCE-7-16 standard in deformation control, and prevention of structural damage due to the ductility that TADAS provides to the global structure. All the structural elements satisfy resistance and service requirements given by AISC-ANSI-36016.

The Corporate Tower is a 33-story building with a total height of 139m and a floor area of 81x56m. The structural systems used were Dual Frame-wall and Special Moment Frame systems with Seismic Detailing, the foundations were of the deep type consisting of interconnected concrete piles through foundation beams and pile caps. This article outlines the guidelines followed for the superstructure and substructure’s structural design, as well as the challenges overcome due to the unique conditions of the project. Given the significance of this endeavor, site response studies were necessary to optimize the structure. Similarly, state of the art standards were implemented in accordance with the latest developments in structural design, such as ASCE7-10 and ACI318-14.

The assessment of intensive care unit-acquired weakness in adult patients at risk of post intensive care syndrome
Authors:   , Van Vuuren Noline
Published: October 2024

Intensive care unit-acquired weakness (ICUAW) is a syndrome of generalised neuromuscular weakness that develops in critically ill patients for which there is no alternative explanation other than the critical illness itself, and which has a prevalence of 25% to 80% in ICU survivors. The diagnosis and grading of ICUAW is made by excluding other causes of neuromuscular weakness and by repetitive clinical examination of muscle strength using the Medical Research Council Sum-Score (MRC-SS). The aim of the study was to evaluate ICUAW, and diagnostic methods available for this condition, in ICU survivors at risk of post intensive care syndrome (PICS) in a South African tertiary public sector hospital. METHODOLOGY: A prospective, single-centre observational study was conducted in a multi-disciplinary tertiary ICU in Eastern Cape. Patients at risk for post intensive care syndrome were included in the study. Patients were evaluated for ICUAW at six weeks and six months post-hospitalisation with the MRC-SS and handheld dynamometry (HDD). Full criteria ICUAW is defined as an MRC-SS of less than 48 out of 60. RESULTS: We enrolled 150 patients in the study, of which 103 patients completed the six month follow-up. At six weeks and six months, respectively, 3 and 2 patients’ MRC SS were less than 48/60. The median MRC-SS was 58/60 (IQR: 52-60) at six weeks and 60/60 (IQR: 58-60) at six months. There was an average change of 32,75% in the mean force from six weeks to six months for all muscle actions on both sides, with p < 0.001 indicating a significant difference. Fair correlations (r = 03-0.5) were observed between the MRC scale and HHD measurements for each muscle action from six weeks to six months. The correlation between the MRC scale and HHD proved to be significant (p < 0.001). CONCLUSION: There is a low incidence of the full criteria of ICUAW in relatively young and previously healthy ICU survivors at risk for PICS. Both the MRC-sum scores and HHD measurements showed a significant improvement over six months and there was an acceptable correlation between them. The findings of this study indicate that the strength assessed by both methods is related and tends to change in a similar direction over time.

Atrial fibrillation (AF) is one of the most prevalent cardiac arrhythmias, associated with a high risk of thromboembolic complications such as stroke. The use of anticoagulants is essential to prevent these events, with warfarin being widely used for many years. However, new oral anticoagulants (NOACs), such as apixaban and rivaroxaban, have emerged as saferand more effective alternatives, especially in vulnerable subgroups like patients with chronickidney disease and the elderly. This study reviews recent literature on the use of anticoagulants in AF patients, comparing NOACs with warfarin in terms of efficacy, safety,and adherence. Nine studies were selected from PubMed and ScienceDirect databases. Theresults indicate that NOACs have a better safety profile concerning hemorrhagic events and are easier to use due to the lack of frequent monitoring requirements. However, warfarin is still widely used, especially in lower-income countries, due to its more accessible cost. It is concluded that while NOACs represent a significant advancement in AF management, their widespread implementation depends on financial accessibility and the individual suitability ofeach patient.

Background : Fanconi anemia (FA) is a rare genetic disorder inherited in an autosomal recessive manner. The clinical phenotype varies depending on the involvement of different genes. Major physical abnormalities mainly affect the limbs and spine.. Methods/Observation : We report the case of an 11-year-old girl from a first-degree consanguineous marriage. The classic triad of short stature, malformation syndrome and early bone marrow failure suggested AF, which was confirmed by the detection of significant chromosomal instability after culture with Mitomycin C, compared with a normal control. Conclusion : This case highlights the crucial role of cytogenetics in the diagnosis of Fanconi anemia and genetic counseling to improve the management of affected children and their families.
