Authors: Karastanev Doncho , Evlogiev Yordan , Tchakalova Boriana , Petrova Vanushka , Nedelcheva Mariana
Published: December 2024

The study aims to analyze the current consolidation status of the Pliocene sediments (Brusartsi Formation) by a geological and geomorphological reconstruction of loading and unloading stages in the Kozloduy lowland. Based on that analysis the overconsolidation margin of the Pliocene bedrock is derived for three terrace levels – T6, T2, T1 where several important nuclear facilities have been constructed and new ones are planned to be built. The elucidation of that matter is useful for the selection of the most adequate soil model in the analysis of deformation and long-term stability of the ground base in the geotechnical engineering projects.

Authors: Dimitrov Orlin , Ranguelov Boyko , Vasilev Atanas , Dobrev Nikolai
Published: December 2024

The aims of the publication are to provide a brief overview of research in Bulgaria to search for earthquake precursors related to gas/methane manifestations mainly in the water area in front of the Bulgarian coast and of known Bulgarian devices for monitoring gas emissions, as well as to propose a new monitoring site of underwater gas sources, and studying the relationship between earthquakes and gas emissions. As a result of conducted neotectonic studies, of Quaternary sediments, based on interpretation of seismoacoustic profiles and detailed seismostratigraphic interpretation of Quaternary sediments, attachment of registered gas sources to active faults was established. This allows the selection of a suitable monitoring site located around the intersection of two suspected fault lines “outlined” by recorded gas springs.
Roughness analysis of the riverbed in the study of torrential events using terrestrial photogrammetry data
Authors: Nikolova Valentina , Filipov Dobromir , Guerit Laure
Published: December 2024

This study examines the riverbed in the lower course of the Damdere River in the Eastern Rhodope Mountains (southern Bulgaria), a region prone to torrential flow events. Two field campaigns were carried out – in October 2023 and October 2024, employing terrestrial photogrammetry to generate high-resolution 3D point clouds for the computation of geometric features of the riverbed. Using CloudCompare open source software, roughness values were calculated from the photogrammetric data and compared with manually measured sediment “b” axis values. Results show that maximum roughness values were higher in 2024, but more significant spatial variability of the roughness across the test site is observed at the 3D point cloud of 2023, likely reflecting sediment transport due to torrential flows. These findings suggest that in the absence of rain gauges, sediment size, and roughness data serve as viable indicators of torrential activity, with local rainfall patterns supporting erosion and sediment displacement.

Authors: Raykova Reneta , Dimova Lyuba , Pandourska Elitza
Published: December 2024

The Earth’s structure is a key factor in studying earthquakes. In most cases, the structure is investigated only through indirect methods, often resulting in a simplified model of the actual structure. Earthquake depth is one of the parameters that strongly depends on the model used. We examine the importance of accurately modeling the Earth’s structure in determining the focal mechanisms of moderate earthquakes. Using three different sets of models in the test region, we obtained three significantly different focal mechanisms. Using a model that closely resembles the real structure is crucial for investigating rupture processes.

AN INVESTIGATION OF THE FLUOROSILICONE RUBBER THERMO-OXIDATION PROCESS AT HIGH TEMPERATURES
Authors: Pazur Richard J. , Tilley A. , Zaman B. , Porter C.
Published: December 2024

Fluorosilicone (FVMQ) rubber is commonly used in many military aircraft applications such as seals and gaskets due to its exceptional heat stability, low temperature flexibility and resistance to fuels and oil. In this investigation, a peroxide cured and silica filled FVMQ rubber compound was prepared and subsequently submitted to accelerated heat aging for up to 50 weeks at temperatures between 75 to 250°C. Heat aged samples were then tested for hardness, physical property characteristics and crosslink density by solvent swell and Double Quantum – Nuclear Magnetic Resonance (DQ NMR). The Arrhenius methodology was applied to the shifted experimental data assuming the principle of time-temperature superposition. The tensile strength and elongation at break both decrease upon thermal treatment. A small stiffness increase was observed by both the hardness and the tensile stress at 10% elongation test data. The characterization of the crosslink density by solvent swell testing was inconclusive. On the other hand, the DQ NMR testing clearly showed that the crosslink density decreases while the number of chain defects increases. The unaged crosslink distribution is heterogeneous in nature displaying much more heterogeneity than peroxide cured silicone. Non-linear Arrhenius behavior was observed between 75 to 250°C with a mechanism change at 175°C. The FVMQ crosslink distribution becomes more heterogeneous with aging. A significant loss of low molecular weight FVMQ due to depolymerization and backbiting reactions was observed at higher aging temperatures. Reactions with the silica surface also occurred with the creation of Si-O bonds. No direct evidence of thermo-oxidative and oxygenation reactions was observed. Reaction mechanisms have been proposed to explain the degradation of FVMQ due to heat aging.
Moments - concerto for violin and orchestra by Ghenadie Ciobanu. Narratological perspective
Authors: Ghilas Victor
Published: December 2024

The author of the article aims to reveal the essence of the music contained in the Concerto for violin and orchestra “Moments” by Ghenadie Ciobanu by analyzing one of its facets with an emphasis on the musicalized narratological discourse from the perspective of the personification of the solo instrument. In order to form a broader vision of the specificity of this creation within contemporary national music, the text follows a chronologically directed route towards this characteristic form of performance. In this sense, a review, supported by some notional clarifications, is made in the form of a synthesis of some historical and contextual landmarks in which the concert repertoire developed with the violin in the foreground. The specific analyzes of Gh. Ciobanu’s Concerto are focused on the narrative levels and qualities of the sound events, having an individualized intonation, which can be found in the opus brought up for discussion. The emphasis of the personified discursive messages of the soloist in symbiosis with the orchestral ensemble, organized in a unitary artistic conception, provides arguments for revealing the expressive and emotional potential of violin music, able to generate deep reverberations of a psycho-emotional nature and projected into the complex world of affective states and experiences.
Trenule for viola and cimbalom by Igor Iachimciuc: compositional and stylistic particularities
Authors: Gîrbu Ecaterina
Published: December 2024

The works of contemporary composer Igor Iachimciuc are distinguished by original approaches that contribute significantly to enriching the national cultural landscape, incorporating strong influences of folklore. His works represent a fusion of the fundamental layers of musical culture: folklore, European professional tradition and mass musical culture. His vision focuses on the concept of cohesion within the contemporary musical sphere and on the exploration of seemingly opposing components such as folklore and traditional jazz, modern compositional techniques and pop music. The work Trenule for viola and cimbalom is subtitled Improvisation on a Romanian folk song, in this case, it is about the well-known urban song Trenule, mașină mică/ Train, little car. The composer demonstrates a postmodernist approach to the folkloric phenomenon, treating the source also through the prism of a specific folkloric element – improvisation. The instrumental piece is an eloquent example of the fusion of elements specific to folklore and jazz based on improvisation, the component that is here part of the composer’s very way of thinking about music, largely marking both the process of constituting the form and the dramaturgical concept of creation.
The song itself, non-casual lyrical genre
Authors: Spinei Damian
Published: December 2024

The present article does not tend to be a full analysis of the non-occasional lyrical genre, in which the song itself has a distinct place and very diverse subjects from the song of military service to that of mourning, longing, alienation, love, nature etc. From a geographical point of view, it encompasses the entire Romanian space, actually making up the heritage of the life and evolution of our nation. In a word, the focus is on revealing inner feelings and emotional states, giving us the opportunity to have a more varied freedom of expression in dealing with the subjects, unlike in occasional music genres which are linked to certain occasions and celebrations. Tackling this topic is essential for us, those who come from the world of music having the firm conviction to establish, follow and grasp where we stand today carried by the wave of the Romanian lyrical song. It displays considerable appearance on television and radio stations, and similarly in various artistic events such as festivals, contests, concerts, etc., in which it is often removed from the patterns of the old repertoire and augmented with new nuances.

This study examines the impact of social and economic factors on community adherence to COVID-19 health protocols in Surabaya, Indonesia, through a supply chain management perspective. It applies the five-component supply chain model encompassing supply chain policies, governance structures, consumer attitudes, process efficiency, and the integration of culture/technology. The primary data is derived from a survey of 119 participants, supplemented by secondary data on national health protocols and local COVID-19 cases. The analysis reveals critical gaps in compliance with health protocols, particularly regarding mask usage, social distancing, and avoiding crowded spaces. Specifically, only 17.6% of religious adherents follow these protocols, while 82.3% do not. In traditional markets, compliance stands at 19.2%, while 80.8% of participants ignore the guidelines. Among the youth, only 12.4% adhere to the protocols, with 87.6% disregarding them. The study highlights the need to improve the supply chain of public health interventions, from awareness campaigns (demand generation) to efficient delivery systems (process optimization) and monitoring mechanisms (evaluation and feedback loops). Emphasizing a supply chain approach, the findings suggest that strengthening the upstream (policy and governance), midstream (public behavior and attitudes), and downstream (cultural and technological adaptations) components can enhance compliance rates and reduce COVID-19 transmission. The study concludes with actionable recommendations, such as increasing public health awareness, strengthening governance frameworks, targeting interventions for vulnerable groups, and fostering multi-stakeholder partnerships to create a resilient health compliance supply chain in Surabaya, Indonesia.

Published: December 2024

Supply chain resilience has rapidly expanded as a research area due to increased vulnerability to disruptions and uncertainties. Integration and re-engineering are essential components of a resilient supply chain that can improve its performance. Nevertheless, no one has yet investigated the effect of Artificial intelligence (AI) on the relationship between integration and re-engineering. Therefore, this study aims at investigating the roles of supply chain integration and re-engineering on supply chain performance. Similarly, it investigated the moderating role of AI in these relationships. This study develops a theoretical framework based on resource-based view and the social construction of technology theory. Based on a quantitative study of 564 responses collected from supply chain and clinical unit managers in the Qatari public healthcare sector, an empirical analysis was made using the partial least squares (PLS) path modelling technique. Results revealed that supply chain integration and re-engineering positively affect supply chain performance. Most significantly, these relationships are found to be positively moderated by AI. This study confirms the impact of supply chain integration and re-engineering on performance, providing empirical evidence for AI's role in strengthening these relationships.

Published: December 2024

Rock extraction is a particularly major step for the preparation of rock samples for core analysis, it can be performed by many traditional techniques like Soxhlet, centrifuge, and flooding system. In this study, a new technique was suggested for core cleaning by microwave. New experiments were conducted as part of this research project, focusing on the cleaning of several types of core plugs under different conditions such as temperature and solvent volume. Additionally, the goal was to extract hydrocarbons from naturally saturated reservoir rocks that had been prepared for standard testing. These findings were then compared with the conventional method of cleaning samples using an organic solvent, specifically toluene.
The experiments successfully employed microwave technology for the cleaning process, effectively optimizing key variables including time, temperature, energy, and solvent quantity. The operational duration was set at 3 hours per day, using 20 ml of solvent, following numerous trials and iterations. This method allowed for the extraction of crude oil from 36 plug samples while achieving complete cleanliness of the rocks. Conducting porosity tests before and after the cleaning procedures showed the absence of any damage to the rock samples. Notably, there was an observed alteration in granular size within an acceptable range of 0.02 to 0.6. Further analyses were conducted, including gas chromatography and infrared analysis, both of which indicated that microwaves had no adverse effect on the crude oil extracted. Conclusively, the use of microwaves in the cleaning of rocks appears as a harmless, economically viable, environmentally friendly technique. The feasibility of this method was proved at the laboratory level, showcasing its potential for wider application.

Authors: Faraj Ali K. , Salih Ameen K. , Abdul Hussein Hassan A. , Abed Al-Hasnawi Ali N.
Published: December 2024

Geomechanical problems are the most important problems that happen in the Zubair oil field; treating these problems requires a lot of time (Non-Productive Time) and thus increases the cost of drilling the well. Wellbore instability, subsidence, reservoir compaction, casing smash, pipe damage, and well kick is the main geomechanical problems facing the drilling process in the Mishrif formation, Zubair oilfield. The main goals of this study are to estimate the changes in stresses and subsequent subsidence values for this field during the production and injection periods. These estimation values, many problems can be avoided, thus increasing the drilling efficiency.
This study is to introduce the one way coupling between the reservoir model and geomechanical model using the finite element method. The finite element technique in CMG 2018 program was used to estimate the stress states during the production or injection operations in this field of interest.
The results of the 3D finite element model showed that the effective vertical stress rises by 32 psi during production while the effective horizontal stress increases by 16 psi. This may be explained by the fact that variations in pore pressure have little or no impact on the total vertical stress generated by weight. The results of this study demonstrated that the finite element method is a conservative method for coupling reservoir geomechanics and fluid flow. Subsidence values were 6.096 mm in the north part of the Al-Hammar dome, while at the center the subsidence was -5.1816 mm. Shuaiba dome has negative subsidence which is about -9.75 mm. It is important to note that the positive results subsidence signify the pore volume compacting, which may have an impact on the permeability and porosity of the reservoir petrophysics. As a result of a negative subsidence deformation, different failures including well casing damage, wellbore failure, and pipe smashing, are expected. Based on these results, production can cause an increase in the differential stress, which leads to rock shear failure and in injection cases, increasing pore pressure can cause a tensile rock failure.

Sich ein Bild machen
Authors: Schweiger Christina
Published: December 2024

Ausgehend von der These, dass Health Literacy wesentlich mit Wahrnehmungs- und Kom­mu­ni­ka­ti­ons­fä­higkeit, Vorstellungskraft, dem Vermögen zum Perspektivwechsel und Empathie in Verbindung steht, wird im Beitrag gezeigt, wie der Kunstunterricht zum Erwerb dieser Kompetenzen beitragen kann. Bei der bildnerischen und rezeptiven Praxis lassen sich innere, d. h. introspektive und äußere, d. h. extraspektive Wahrnehmungen anregen und intensivieren. Sie sind Voraussetzung für Einblicke und Auskünfte über Empfindungen und das eigene Befinden und machen zugleich empfindsam für die phy­si­sche und psychische Verfasstheit anderer. Sich ein Bild vom eigenen und dem Zustand seiner Umwelt ma­chen zu können, ist ein wichtiger Schritt bei der Entwicklung von Health Literacy.
Gesundheitsförderung in der Schule – ein systemischer Blick
Authors: Hauser Larissa , Caviezel Cathy
Published: December 2024

Eine wichtige Voraussetzung, um Schulen lern- und gesundheitsförderlich zu gestalten, sind gesunde und motivierte Mitarbeitende und Schulleitungen, die positive Beziehungen vorleben und fördern. Um die Resilienz der ganzen Organisation zu stärken und nicht nur die von einzelnen Personen, sollte sys­temisch vorgegangen werden. Ausgangspunkt eines Prozesses zur Betrieblichen Gesundheitsförderung ist eine sorgfältige Analyse der vorhandenen Belastungen und Ressourcen, die massgeschneiderte Pro­blemlösungen auf verschiedenen Ebenen ermöglicht. In Bezug auf den Fachkräftemangel bietet sich Schulen damit auch die Gelegenheit, sich als attraktive Arbeitgeberinnen zu positionieren, die Bindung der bestehenden Mitarbeitenden zur Organisation zu stärken und Kündigungsgedanken zu reduzieren.

As libraries increasingly integrate Artificial Intelligence (AI) to enhance operations and user experiences, data privacy has emerged as a critical concern. Libraries collect vast amounts of user data, including borrowing histories, digital interactions, and demographic information, making them susceptible to privacy risks such as unauthorized access, data breaches, and algorithmic profiling. This study investigates the role of ethical AI practices in addressing these data privacy issues, ensuring trust, transparency, and compliance with global privacy standards. Ethical AI emphasizes principles such as user consent, data ownership, and the minimization of bias, which are essential for safeguarding privacy in library systems. Privacy-preserving AI techniques, including differential privacy and federated learning, offer robust solutions by anonymizing data and enabling decentralized processing. Additionally, encryption, secure storage methods, and real-time monitoring systems enhance data security while mitigating risks of unauthorized access. This highlights the importance of explainable AI (XAI) in fostering user trust by ensuring transparency in how AI systems process and utilize data. Ethical frameworks tailored for libraries emphasize stakeholder involvement, accountability, and adherence to global privacy regulations such as the GDPR and CCPA. Case studies of libraries implementing ethical AI demonstrate the feasibility and benefits of these practices, including improved user confidence and compliance with legal standards. However, challenges such as balancing personalization with privacy, addressing resource constraints, and overcoming resistance to change are explored. Recommendations include fostering global collaborations, advancing open-source ethical AI tools, and conducting regular audits to uphold privacy standards. By advancing ethical AI practices, libraries can build secure, user-centric ecosystems that protect data privacy while leveraging AI’s transformative potential. This research underscores the necessity of proactive measures to ensure libraries remain trusted guardians of information in the digital age.
Thermodynamic Analysis of an Air Source Heat Pump for Kırıkkale Province
Authors: Tan Hüsamettin , Pehlivanlı Zühtü Onur
Published: December 2024

This study conducted a thermodynamic analysis of an air-source heat pump using R32 refrigerant to assess its effectiveness in meeting the heating needs of a residence in Kırıkkale province during winter. The air temperature in Kırıkkale was obtained from the Turkish State Meteorological Service according to the average of last ten years. Calculations were based on the heating season between October and April for the years 2022-2023. In the study, parameters such as heat gained from the environment, compressor energy consumption, the system's performance coefficient, and second-law efficiency have been examined. As the external air temperature decreases, the amount of gained heat decreases by approximately 9%. In this regard, the energy consumption of the compressor to meet heating demand has increased by approximately 40%. The results showed that the system performance was calculated as 5.545 and 3.957 for October and January, respectively. However, the second-law efficiency was observed to be 0.3266 for January and 0.2103 for October. The findings emphasize the varying performance of air-source heat pumps depending on climatic conditions.
Banco de España Business Activity Survey: 2024 Q4
Authors: Fernández Cerezo Alejandro , Izquierdo Mario
Published: December 2024

Rationale

The Banco de España Business Activity Survey (EBAE) provides highly valuable, real-time information on a broad sample of Spanish firms’ turnover, employment, costs and prices. This helps to diagnose current economic developments.

Takeaways

•Firms perceive an increase in turnover in 2024 Q4, compared with the decreases in the same quarter of 2022 and 2023. Those located in the Valencia region have reported adverse turnover developments as a result of the impact of the flash floods.

•Inflationary pressures have ticked up slightly in Q4, in both the cost of inputs and selling prices.

•The percentage of firms affected by higher borrowing costs and insufficient demand has fallen, but economic policy uncertainty and labour shortages remain high.

•In a module on advanced technologies, 3% of respondent firms reported a high or moderate use of artificial intelligence (AI) systems and 11% are experimenting with them. For firms not yet using AI, the main barriers are a lack of skilled staff, prohibitive costs and significant uncertainty about the legal ramifications.
Accounting for funds created and used in the activities of non-commercial organisations
Authors: Harea Ruslan
Published: December 2024

The funds created by the non-commercial organizations represent the part of the capital of the non-commercial entity formed from the capitalized resources of the pre-destined means received in the form of special purpose financing prior to their use. This article presents the order of formation of funds depending on the sources from which they are created and how to use them further. At the same time, the need to use the accounting of special purpose financing is explained based on the application of the necessary funds in provisionally created funds in the available capital of non-commercial organizations. It also presents alternative ways of capitalizing on funding from different sources (predestined or unpredestined) with their accounting model in the daily activities of non-commercial organizations in the Republic of Moldova. This study examines the principles and standards governing NCO accounting, identifies challenges in fund management, and proposes best practices to enhance financial reporting and accountability. Methodologies include comprehensive literature reviews, bibliometric analyses, and case studies to illustrate the practical application of theoretical concepts.
