The study of the processes occurring in the temperature range of the main decomposition of the organic mass of coal (OMC) makes it possible to understand both the general patterns and the specifics of the decomposition of solid fuels. This temperature interval is used to calculate the kinetic parameters of the process, which carry important information both about the nature of the structural-chemical transformations and about the structure and direction of thermal destruction of OMC. In this article, to study the kinetics of pyrolysis of coal, the method of thermogravimetric analysis was used, in which heating of coal samples was carried out in ceramic crucibles in the temperature range of 25-900 °C at different heating rates (5-25 deg/min) in nitrogen and oxygen media. Coal from the Kenderlyk deposit was chosen as the object of study. Based on the constructed differential DTG curves (dependence of the sample mass change rate on time) at different heating rates, the kinetic parameters of pyrolysis of coal were calculated using the equations of non-isothermal formal kinetics. The effect of the rate and temperature of coal heating on the kinetic parameters of pyrolysis of coal has been studied. The main stages of OMC decomposition are revealed. It has been found that the heating rate of coal samples significantly affects the temperature and process rate corresponding to the main decomposition maxima on the differential DTG curves. The dependence between the kinetic parameters of pyrolysis of coal in the temperature range of the main decomposition of OMC on the rate and temperature of heating, as well as between the kinetic parameters at different stages of the main decomposition of coal, is analyzed.
APPROACHES TO MEASURING THE CREATIVE ECONOMY AND TRENDS IN THE DEVELOPMENT OF THE IT SECTOR: THE IMPACT OF DIGITAL TECHNOLOGIES ON CREATIVE INDUSTRIES

Published: July 2024

Today, the creative economy is often referred to a the new oil. According to UN estimates, creative industries generate around 30 million jobs annually, contributing $2.25 trillion to the global GDP. Projections indicate that by 2030, the global creative industry's turnover will increase by an additional 40%. This sector creates high-income jobs, especially for talented youth.
In Kazakhstan, investments in the creative industry have increased more than fourfold over the past decade. Currently, 3.5% of the country's total employed population, or 310 thousand people, work in this sector, contributing 2.7% to the economy. To unlock this sector's potential, the government is developing the Concept for the Development of Creative Industries for 2021-2025, establishing a unified vision for growth.
The concept of creative industries varies across countries, lacking a universally accepted definition. Reports like Australia's "Creative Nation" (1994) and the UK's "Creative Industries Mapping Document" (1998) have significantly influenced global perspectives. The UN recommends a classification into four aggregated blocks, but terminology differs across organizations, with UNESCO using "creative industries" and the EU referring to "cultural and creative industries."
Creative industries encompass sectors built on creativity, intellectual property, and technology. Definitions differ, but common sectors include design, art, fashion, and more. Measuring the creative economy involves various approaches, such as industry assessment, employment analysis, and trade in creative goods and services. The "creative trident" concept evaluates employment in specialists, supporting roles, and integrated positions.

Authors: Krstić Nikola , Stefanović Nikola , Petronijević Milan , Damnjanović Ivana
Published: July 2024

Introduction/Aim. Polypharmacy can increase the risk of side effects and cause adverse drug interactions with a significant impact on the course of the basic disease. The aim of the study was to determine the frequency of polypharmacy and examine its impact on the risk of drug-drug interactions in patients with rheumatoid arthritis (RA). The research was conducted in the form of a retrospective cross-sectional study. Material and methods. The study included 131 patients diagnosed with RA, treated during 2019 and 2020. Demographic data and clinical characteristics of the subjects were collected from the medical documentation (presence of comorbidities, prescribed therapy and number of drugs). In the study, polypharmacy was defined as the use of more than five drugs, regardless of the length of therapy. Results. The data analysis of the therapy used by patients showed that 84 subjects (64.12%) used 5 - 9 drugs, both for the treatment of primary and for the treatment of other present acute and chronic diseases. The analysis of the collected results identified potential interactions in 86 respondents (65.65%), while the total number of potential interactions was 164. The most common potential interactions were serious (73.78%). Analyzing the obtained results, it appears that aceclofenac is the drug that has the potential to enter into the largest number of interactions with the drugs used in the therapy of RA. Conclusion. Given the wide range of available drugs and therapeutic modalities used in the treatment of RA, it is necessary to choose the right combination of drugs in order to achieve the desired therapeutic outcomes and minimize potential drug-drug interactions.

Authors: Bokan Vesna
Published: July 2024

Introduction. Research into patients with lower limb amputation (LLA) puts strong emphasis on quality of life (QoL) and importance of the research in that regard as a measure for the rehabilitation outcomes. The aim of this study was to show which aspects of QoL are related to the duration of wearing a prosthesis in patients with transtibial amputation (TTA). Methods. The study sample comprised 40 patients who used prosthesis for 1 - 3 years (group A), 4 - 7 years (group B) and > 8 years (group C). All patients completed Trinity Amputation and Prosthesis Experience Scale-Revised (TAPES-R). Results. Prosthesis wearing history was significantly different between the groups: group A (2.2 ± 0.7 years), group B (5.5 ± 1.3 years) and group C (22.9 ± 13.6 years), p<0.001. Patients in group B were significantly (p < 0.05) older compared to patients in group C, displayed a significantly (p < 0.05) lower rate of employment and significantly (p < 0.05) longer duration of diabetes mellitus. Patients in group C displayed a significantly (p = 0.005) lower rate of diabetes mellitus. TAPES-R showed that social adjustment was significantly lower (p < 0.05) in patients in group C compared to patients in group A (3.14 ± 0.46 vs. 3.55 ± 0.41). Conclusion. Although patients with TTA showed good QoL, the group with a long history of wearing a prosthesis differed significantly in social adjustment compared to patients with a short period of wearing a prosthesis. The age and etiology of amputation differed significantly between the groups.

In Cyprus, a strategic plan for the provision of dental services is described. An oral health promotion programme for elementary school children and universal preventive programme for children ("dentist pass") have been implemented in Greece. Serbia has a national preventive programme that has expired, but the programme activities still apply. Albania, Bosnia and Herzegovina, Montenegro, Romania, and Turkey do not have national oral health preventive programmes. Countries in the region with no oral health promotion programmes have poorer oral health indicators compared to countries with existing programmes. Conclusions: While countries in the Balkan Peninsula have made progress in improving the oral health of their inhabitants, the absence of national oral health promotion programmes is striking in many countries in the region. Greater involvement of the community in activities to maintain and improve oral health is needed, as is more comprehensive dental care for vulnerable populations. This paper (Part I) compares national oral health promotion programmes of the Balkan countries, the key measures and activities, and general and specific objectives of the programme.

Background/Aim: Association of a supra-radicular attachment with a removable partial denture on a metal framework is a therapeutic solution that may overcome the biomechanical and aesthetic challenges associated with extensive edentulism. The objective of this article is to describe, through a clinical case report rehabilitation of a partially edentulous patient with a partial removable denture using a supra-radicular attachment and to illustrate the advantages and disadvantages of this prosthetic device. Case Report: A 43-year-old, female patient in good general health, was addressed to the removable partial denture department at the Monastir Dental Medicine Clinic. The prosthetic decision was to fabricate, in the maxillary arch a metal framework with a radicular post equipped with an axial attachment at tooth 15, and a metal framework RPD replacing the missing teeth. In the mandibular arch, a metal framework RPD was planned with an evolving design considering the poor prognosis of tooth 46. Conclusions: The integration of the supra-radicular axial attachment into the metal framework of a removable partial denture represents a good therapeutic solution to overcome the biomechanical and aesthetic challenges posed by extensive edentulism. However, treatment success requires thorough preliminary study, a correct indication, and patient cooperation.
Innovation in the defence industry from the end of the Cold War to the war in Ukraine
Authors: Mészáros Alexandra
Published: July 2024

Since the end of the Cold War, the defence industry has emerged as a leader in innovative technologies, and the Russo-Ukrainian war has provided a unique opportunity to test these technologies in a real combat scenario. As a result of the geopolitical events of February 2022, the European defence industry has faced unprecedented political, economic, and technological changes. This study examines these transformations through semi-structured, open-ended, in-depth interviews with twenty-five experts across ten European countries, analysed using qualitative content analysis, with a focus on small and medium-sized enterprises (SMEs). While perspectives on the necessity of defence innovations vary, there is considerable market demand for both disruptive innovations and the advancement of conventional technologies. However, despite the theoretical benefits, the current uncertain environment leads policymakers to view international defence collaborations as insecure. Consequently, SMEs develop military technological innovations either independently or with domestic partners. This study's novelty lies in its foundation on real empirical data, contributing practically applicable insights to the existing literature on the subject.
On "Westsplaining," realism, and technologies of the Self: A Foucauldian reading of the realist commentary on Ukraine
Authors: Kazharski Aliaksei
Published: July 2024

The article offers a Foucauldian reading of the Western realist commentary on the Russo-Ukrainian war which often faces the charges of "Westsplaining. " It situates this commentary in the broader context of knowledge production and the power-knowledge nexūs it reproduces and conceptualizes realism as a discourse in the Foucauldian sense. As the article argues, this conceptualization allows one to capture its specific technologies of power which, in this case, can be understood as a form of technology of the Self, or, in other words, the disciplining of the collective subjects of world politics (nation-states) through the specifically realist constructs of rationality and prudence that all states are expected to adhere to in the making of their foreign policy. Additionally, the article suggests that this conceptualization of realism as a discourse can be analytically helpful in making sense of the way in which very different genres such as academic research and the op-ed policy commentary, frequently provided by realist IR scholars, are connected through the political economy of knowledge production, thus forming a relationship of discursive symbiosis and mutual legitimation.

Information security in automotive industry: Mechanism TISAX
Authors: Raković Radoslav
Published: July 2024

With the development of information technologies and their application in all spheres of activity, information security has become an actual problem. A significant step towards solving that problem was the adoption of the ISO/IEC 27000 family of standards for information security management systems (ISMS). The practical application of these standards showed that the generic standard cannot satisfy all specific requirements for information security in certain areas, so the adoption of sector standards in areas such as telecommunications, electric power systems, cloud computing, etc. At the same time, in some branches of industry, special standards were adopted to express their specificities. One of those areas is the automotive industry, where the TISAX mechanism has been established to ensure that suppliers comply with information security requirements, especially when it comes to information related to prototypes. This paper provides a summary of the TISAX mechanism, its structure and constituent elements, as well as its relationship with the ISO/IEC 27000 family of standards.
Role of Business Correspondents (BCs) in Financial Services – Reaching in Unreached Rural Areas – A Case Study in Tamil Nadu
Authors: Kandasamy DHEVAN
Published: July 2024

BCs are honest workers working in rural India, elevating the country from the viewpoint of financial services to world-level recognition in terms of financial inclusion by opening bank accounts and collecting deposits, as well as other financial services having networks with commercial banks. As per the Reserve Bank of India’s (RBI) FY22 annual report, the total number of business correspondents in villages has increased from more than 11.9 lakh in 2020 to 18.44 lakh in 2021, reflecting the penetration and scale that banks generate partnering with BCs. Ultimately, the rural people who opened a bank account under PMJDY got the benefit. With this background, the study has attempted to study the role played by the BCs in rural areas and to find the problems faced by the BCs, especially women, while rendering services. This present research is carried out based on a case study method and is descriptive in nature. The study was undertaken purposefully in two districts of Tamil Nadu, Dharmapuri and Dindigul. In Dharmapuri, the Indian Bank Morappur Branch and in Dindigul District, the Canara Bank Gandhigram Branch have been selected for the study. It was concluded that the average salary for the BCs here ranges between Rs. 3000 and Rs. 6000. It should be increased considerably; otherwise, the BCs will try to charge additional money from the account holder for their doorstep services. Adopting the BC model in the cooperative sector leads to faster financial inclusion.
Unravelling the potential of hydrogen in biological systems
Authors: Russell Grace
Published: July 2024

Molecular hydrogen (H2) and oxyhydrogen (66% H2/ 33% O2) gases have been demonstrated to remediate the effects of numerous diseases in adults[1-4]. By acting as an anti-inflammatory and antioxidative agent, it is reported that H2 can improve recovery through mitigating hyperinflammatory responses and reducing oxidative stress[5-7]. As the precise mechanisms of H2 activity are currently undefined, the lack of primary target identification, coupled with difficulties regarding administration methods (e.g., dosage and dosage frequencies, and long-term effects of treatments), there is a requirement for H2 research to evidence how it can reasonably and effectively, be incorporated into healthcare.

Better representation of the limits of RGB and CMYK colour spaces
Authors: Greim Christian
Published: July 2024

Limits of RGB colour spaces are normally displayed as triangles in the CIE Yxy colour space. This type of diagram has the advantage that additive colour mixtures from two light sources actually all lie in a straight line. But CIE-Yxy colour space does not have uniform colour distances. So, a representation in other colour spaces with better equal spacing, such as CIE-Lab, shows better how good or bad the colour spaces really are.
Limits of an offset CMYK colour space were usually determined only at the six corners of the primary colours and the first-order mixed colours in CIELab. It is much more meaningful to determine the limits of the most saturated colours in 10% increments.
The new visualisations were created using the Python library www.colourscience.org. The possibilities and limitations of this library will also be briefly explained
