The rural population in the Dry Zone of Sri Lanka is largely affected by Chronic Kidney Disease of Unknown etiology (CKDu). According to the multidisciplinary research carried out so far, quality of groundwater is considered one of the possible causative factors for CKDu. Therefore, assessment of the quality of groundwater being used for drinking and its evolution mechanism is the key to identifying the linkage between CKDu and drinking water. This study aimed to perform a detailed investigation on groundwater sources using isotopic, chemical, and hydrogeological methods in the CKDu-endemic (site A) and the control area (sedimentary formation—site B) in the Malwathu Oya basin and the control areas in the Malala Oya basin (site C) selected for a systematic comparison. Our investigation shows that elevated levels of TDS, magnesium, and fluoride in the shallow groundwater affected by climatic, geochemical, and hydrogeological processes may contribute to the CKDu in the Dry Zone of Sri Lanka. All the groundwater samples analysed have exceeded the hardness threshold. Prominent Mg hardness proportion together with excess F− in the CKDu endemic area may produce nephrotoxic MgF2 complexes that may trigger renal damage. In contrast, NaF complexes in the CKDu control area leads to reduction of F− toxicity in the human body. Elevated F− and Mg2+ are found in site A, low F− and high Mg2+ in site B, and either combinations of low F− and low Mg2+, high F− and low Mg2+, or low F− with high Mg2+ in site C. TDS, hardness, Mg2+, Na+, and F− are formed with different mechanisms in the three selected areas. The primary process that regulates the evolution of groundwater types and contents in sites A and C is the weathering of silicates. Similarly, in site A, carbonate dissolution and reverse ion exchange are quite strong. Cation exchange and evaporite dissolution are more pronounced in site C. Shallow groundwaters are evapo-concentrated, hence their quality deteriorates more significantly than the deep groundwater in the CKDu endemic area. Dilution decreases the ion content in site A while evaporite dissolution increases it in site C after the rainy season. Evaporation and seawater mixing affect the quality of groundwater in site B. It is also found that a statistically significant difference exists in the F−/Na+, F−/Mg2+, and F−/Ca2+ between the endemic and control areas. Intensive rock weathering combined with desorption has added excess F− to the groundwater in site A, while cation exchange and fluorite dissolution are contributing factors in site C.

Published: June 2024

Developed and in operation since 2019, the information and analytical Energy Resources Management System of the Belgorod Region (ERMS) ensures the digitalization of processes related to the provision of measures to improve energy efficiency related to the powers of state authorities of the constituent entities of the Russian Federation and local governments. The SEER uses methods for assessing the energy efficiency of large geographically distributed consumers of utility resources based on an individual analysis of the characteristics and heat consumption of individual buildings. Currently, the SEER includes information for 2,144 municipal and regional institutions in the Belgorod region, which operate in 5,332 buildings. Costs for energy resources and water in 2023 in these institutions amounted to 4.8 billion rubles; over the five years of operation of the SUER, they decreased by 8% under comparable conditions. Based on SEER data, the total savings potential that can be achieved in regional and municipal institutions of the Belgorod region is 14.3% of annual costs for energy resources and water, including 0.8% from organizational activities and 13.5% from technical measures with an average payback period of 6 years. During 2021–2024, pilot projects for the implementation of SEMS were implemented in 9 Russian regions and one organization, which showed savings potential ranging from 4.4 to 29.5%.
ANALYSIS OF TECHNICAL SOLUTIONS TO INCREASE THE EFFICIENCY OF WATER BOILERS FOR WASTE COMBUSTION IN A FIXED BED AND CHOICE OF FLUE DESIGN FOR DESTRUCTION OF HARMFUL SUBSTANCES IN COMBUSTION PRODUCTS
Authors: Ashraf Ahmed , Trubaev P. , Ramazanov R.
Published: June 2024

The purpose of the work is to analyze technical solutions used to improve the efficiency of hot water boilers for waste combustion. As a result of the analysis of available design solutions for low-power water heating boilers, in which waste is burned in a fixed bed, their main disadvantages were identified: low combustion temperature; ineffective heat transfer from combustion products to the coolant; contamination of flues and heating surfaces; incomplete combustion of fuel; the impossibility of accurately regulating the combustion process, which leads to the formation of a large amount of harmful emissions and a decrease in the heat output and efficiency of the boiler. It is proposed to install a flue after firing the boiler, in which the gases will remain for more than 2 seconds and the organic harmful substances contained in the combustion products will be completely destroyed. To determine the passage time and select the optimal design of the gas duct, a numerical simulation of the movement of the gas flow was carried out using the developed numerical model implemented in the ANSYS Fluent software package. To ensure uniformity of the gas flow in the gas duct, options with different heights of the window between the firebox and the gas duct and the installation of a dividing partition in the gas duct to organize two-pass gas movement were considered. The best results were obtained for a horizontal flue. For further design development and search for ways to increase the residence time of gas in the gas duct, the most effective option with a horizontal gas duct was chosen.

Published: June 2024

Purpose: This study uses the human capital approach and the entrepreneurial cognitive approach to investigate the relationship between business ownership experience and opportunity identification. Additionally, it considers the mediating role of cognitive styles. Study design/methodology/approach: The hypotheses were tested using path analysis, which included the examination of mediation. Sample and data: A questionnaire was used to collect data from 294 Egyptian entrepreneurs.Results: The findings suggest an association between business ownership experience and, analytical style and opportunity identification. The paper also found an association between the analytical style and the number of opportunities. Both intuitive and analytical styles are associated with the innovativeness of opportunities. Furthermore, this study revealed that analytical thinking only partially explains the relationship between business ownership experience and opportunity identification.Originality/value: This study’s value lies in testing the relationship between business ownership experience and opportunity identification in a new context, using a sample of Egyptian entrepreneurs. It also offers a relatively unexplored perspective on the relationship between business ownership experience and opportunity identification. Additionally, the findings challenge the common assumption that prior experience is a source of intuition. The study revealed that experienced entrepreneurs prefer analysis to enhance their ability to identify opportunities.Research limitations/implications: This research’s insights are somewhat limited due to using a non-probability sample. The paper examined entrepreneurs’ cognitive styles without exploring their actual use of intuition and analysis. Despite these limitations, this paper has implications for entrepreneurship research and policy development.

The right to be forgotten concerning the criminal past
Authors: Anderez Belategi Mikel
Published: June 2024

Do offenders have a right “to be forgotten”? What is the content of this right, and against whom can it be exercised? These questions have become more pressing with the irruption of new information and communication technologies, which entail a new risk of perpetuating a virtual criminal record. The growing role of the digital archives of the press has led some jurisdictions to adopt different measures to anonymise or de-reference personal data. The Strasbourg Court, historically reluctant to accept any interference with the initial publication of personal data concerning convicted offenders, has recently dealt with the compatibility of different measures involving the anonymisation or de-indexing of news articles in the digital archives. This contribution describes these recent legal developments, focusing on the criteria developed by Strasbourg to assess the legitimacy of anonymisation measures adopted by States in response to right-to-be-forgotten requests against the media.

Sanctions as a non-monetary factor of inflation in the conduct of monetary policy
Authors: Markina V. S.
Published: June 2024

Aim. To determine the degree of influence of the sanctions policy on the inflation dynamics of Russia within the framework of the monetary policy.

Objectives. To review the current trends of sanctions policy as a non-monetary factor of inflation; to assess the degree of impact of sanctions on the inflation rate in Russia, taking into account a number of other factors on the basis of macroeconometric modeling in the short term; to substantiate the recommendations for taking into account non-monetary factors of inflation for the implemented monetary policy.

Methods. To analyze the current state of sanctions policy as a non-monetary factor of inflation, the study applies comparative analysis and econometric modeling based on the vector autoregression model.

Results. On the basis of econometric modeling of the impact of sanctions on inflation dynamics, based on the data of Rosstat and Investing.com on the inflation rate, ruble/US dollar exchange rate, RTS index, oil prices from 2000 to 2023, we obtain the following results. Sanctions as a non-monetary factor has a significant impact on inflation dynamics. In turn, oil prices do not affect inflation dynamics in the short run.

Conclusions. Sanctions should be taken into account in the formation and forecasting of inflation. Oil prices do not have a significant impact on inflation, but it is important to take into account the volatility of the oil market when forecasting inflation dynamics. The struggle of the Central Bank of the Russian Federation (RF) with non-monetary inflation by monetary methods does not always lead only to a positive result. Therefore, the control of non-monetary factors of inflation should be carried out in the comprehensive work of macroeconomic policy, not only monetary policy.

Objective: To analyze the temporal trend of tuberculosis cure indicators in Brazil. Methods: An ecological time-series study using administrative data on reported cases of the disease nationwide between 2001 and 2022. We estimated cure indicators for each federative unit (FU) considering individuals with pulmonary tuberculosis, tuberculosis-HIV coinfection, and those in tuberculosis retreatment. We used regression models using joinpoint regression for trend analysis, reporting the annual percentage change and the average annual percentage change. Results: For the three groups analyzed, we observed heterogeneity in the annual percentage change in the Brazilian FUs, with a predominance of significantly decreasing trends in the cure indicator in most FUs, especially at the end of the time series. When considering national indicators, an average annual percentage change of -0.97% (95% CI: -1.23 to -0.74) was identified for the cure of people with pulmonary tuberculosis, of -1.11% (95% CI: -1.42 to -0.85) for the cure of people with tuberculosis-HIV coinfection, and of -1.44% (95% CI: -1.62 to -1.31) for the cure of people in tuberculosis retreatment. Conclusions: The decreasing trends of cure indicators in Brazil are concerning and underscore a warning to public authorities, as they point to the possible occurrence of other treatment outcomes, such as treatment discontinuity and death. This finding contradicts current public health care policies and requires urgent strategies aiming to promote follow-up with patients during tuberculosis treatment in Brazil.

Published: June 2024

The electric vehicle's most crucial component is its battery, which provides the vehicle with power. A key element of electric vehicles (EVs) is the battery management system (BMS), which ensures the safe and efficient functioning of the battery pack. Previous research on electric vehicles has identified some drawbacks, such as lengthy charging times and the need for different charging methods depending on battery capacity and temperature. In the proposed work, the battery's state of charge and remaining capacity will be estimated by measuring the voltage and current with the use of a current sensor and temperature monitor. The novelty of the work lies in its ability to increase the range of electric vehicles. This is achieved through higher energy densities in high-voltage batteries, which allow for longer driving distances between charges. Additionally, faster charging systems can handle higher charging power levels, resulting in quicker charging times. These improvements in performance are made possible by the use of high-voltage batteries, which provide the necessary power for greater peak speeds and improved acceleration. As electric mobility becomes more widespread, the ability to accurately predict charging times based on layout becomes crucial in building user confidence, optimizing energy grid management, and promoting the widespread adoption of electric vehicles.

Published: June 2024

The oil and gas industry face significant risks of explosions, often due to factors like gas and oil leakage as well as external corrosion. These substances are highly flammable, and even minor leaks can create volatile environments where the smallest spark can lead to catastrophic explosions. While internal corrosion in pipelines receives attention, external corrosion is often overlooked. Over time, pipeline coatings deteriorate, leaving them susceptible to external corrosion, which can result in leaks, endangering workers and the environment. Detecting and addressing corrosion promptly is crucial for preventing accidents and environmental harm. To address these challenges, a pipeline monitoring system has been developed using a Raspberry Pi Model 3B+ and advanced sensors. This system continuously monitors temperature, pressure, and external corrosion along pipeline routes. It utilizes a K-type thermocouple and a 1.2MPa pressure transducer for real-time data collection. Additionally, a laptop camera integrated with YOLOv8 enables visual inspection for detecting corrosion. The Raspberry Pi processes sensor data and images, triggering alerts for anomalies like temperature or pressure drops indicating leaks, or corrosion spots identified by YOLOv8. The system interfaces with ThingSpeak for remote data visualization and analysis, empowering operators to make informed decisions and take prompt corrective actions.

Is contemporary school and its current organizational culture ready to implement the idea of an inclusive education? This is the question that we attempt to answer by examining the organizational culture of one of the schools in Gdansk, which has been an inclusive institution for over 26 years. In this article we suggest that, in order to promote the idea of “a school for everyone”, the changes are necessary in the multidimensional structure of Polish schools, particularly in the school culture. Our research on this issue leaves no illusions about the unfavourable perspective of the inclusivity promoted by the functioning school. Therefore, the mentioned change in this area seems obvious. In order not to become merely an external facade of transformation, the inclusive model of education should mobilize all of the participants of the educational process to a real change in thinking about education, to pedagogical collaboration and open participation within the frameworks of an inclusive culture.

Published: June 2024

Abstract Cardiac tumors are rare entities, among which atrial myxoma (AM) stands as the most frequent, accounting for approximately half of all reported cases. The incidence of AM is estimated to range from 0.001% to 0.3% within the general population, yet only about 0.06% of these cases present with coronary embolic events. We report on a 33-year-old male smoker who experienced acute, severe precordial pain radiating to the left upper limb, lasting for one hour. The electrocardiographic evaluation demonstrated ST-segment elevation in leads D2, D3, and aVF, alongside significantly elevated serum troponin levels, confirming a diagnosis of ST-segment elevation myocardial infarction (STEMI). Subsequent coronary angiography revealed proximal occlusion of the right coronary artery due to thrombus. An initial attempt of thrombus aspiration was unsuccessful, followed by primary angioplasty with balloon inflation without stent placement. Further diagnostic exploration through transthoracic echocardiography identified a homogenous, smooth-surfaced mass measuring 5.2 cm x 2.3 cm attached to the interatrial septum. This mass, characterized by lobulations, prolapsed into the mitral valve and left ventricle during diastole, consistent with AM. Surgical resection of the mass was successfully performed, with the patient being discharged asymptomatic. In the reported case, the patient's profile, notably his age, and gender, diverges from the typical epidemiological characteristics associated with AM. This case adds to the limited number of reports where the inferior wall is affected by the right coronary artery being occluded. This report emphasizes the significance of differential diagnoses in younger patients presenting with STEMI.

POLITECONOMY – FROM «CAPITAL» TO MODERNITY
Authors:   International Engineering Academy, Moscow, Russia, Tarkhanov O. V.
Published: June 2024

The article shows that the economic theory of the production of utilities and their distribution in society, originating in the works of Aristotle and formed into the science of “Political Economy” in the works of Petty, Kene and Smith, through Hegel’s dialectics and Liebig’s theory of mineral fertility, became an integral part of the doctrine of human society in the works of Marx and Engels. These works indicate that “the production of food is the very first condition of life ... for producers and all production in general.” Since that time, farming in the world has been carried out according to the recommendations of the teaching of «Agrochemistry», as a modern paradigm of agriculture, the basis of which is Liebig’s theory. Justifications are given for the fallacy of this theory, and the implementation of the paradigm leads to the degradation of the natural soil fertility of the land, the growth of unproductive costs in agriculture, the weakening of states and is the main reason for the growing threat of famine and the approach of the world to war for the remaining fertile lands.

The article studies the financial possibilities of modernizing industrial enterprises of the Russian Federation. The relevance of the research topic lies in the need to increase the competitiveness of industrial enterprises of the Russian Federation in a rapidly changing economic environment. Internal financial capabilities play a key role in modernizing production facilities, introducing new technologies, increasing production efficiency and improving product quality. Taking into account sanctions and changes in the global market, Russian industrial enterprises are faced with the need to update equipment, increase labor productivity and reduce costs. A study of internal financial opportunities for modernization of industrial enterprises in Russia will help identify potential for growth and determine development strategies that contribute to the sustainable development of the industry and the economy as a whole. Small, medium and large mechanical plants are considered as the object of research. The subject of the study is the economic, organizational, financial and production relations of modernization of industrial enterprises of the Russian Federation. The purpose of the study is to study the financial possibilities of modernizing industrial enterprises of the Russian Federation. The article proposes methodological support for studying the financial possibilities of modernizing industrial enterprises using the example of Russian mechanical plants. During the study, it was highlighted that in conditions of external restrictions and insufficient access to credit resources, industrial enterprises have the opportunity to modernize by using a mechanism to increase the share of cost in the enterprise's revenue. These opportunities depend on the volume of production of the enterprise and its diversification. This approach has a number of limitations, but in the realities of the current economic situation it can be used both by enterprises themselves and by government authorities to modernize production. The results of the study can be used for further research in the search for intra-organizational reserves for the development of enterprises.

The effect of the 2009 cancer coverage expansion policy in Korea
Authors: Lee Changwoo
Published: June 2024

This study focuses on the effect of coverage expansion policy on medical expenditures at each initial medical expenditure level. More specifically, how each structural change, such as the enforcement of coverage expansion policy and other observable factors, influences the spending on medical care using the relatively recently developed decomposition technique was investigated in the study. The results showed that those at the lowest or highest medical cost level benefited most from the policy change. The observable variables seemed to affect the overall differences in the cancer inpatient cost for those at the middle medical cost level, and the structural changes seemed to account for the overall change in the cancer inpatient cost for those at the lowest or the highest medical cost level. The findings of this study offer an explanation for why the coverage expansion policy could not affect the equity in health utilization and financial burden reported in previous literature.

The coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, has been a global concern since the onset of the pandemic. Vaccination has emerged as an effective intervention to prevent infection, alleviate severe clinical symptoms, and reduce mortality rates. COVID-19 vaccines, approved by the World Health Organization and other health regulatory bodies, have been administered worldwide, including in Nigeria. However, vaccine hesitancy has hindered the widespread uptake of the COVID-19 vaccine. This study, conducted between December 2021 and May 2022, aimed to assess factors influencing COVID-19 uptake within public health-care settings and the roles of health-care professionals in influencing vaccine uptake. A total of 366 health workers from randomly selected primary health centers in the Ilorin metropolis participated in this study, responding to the Barrier Analysis questionnaire. Chi-square analysis was utilized to determine relationships between variables and their significance. Our findings revealed trust in vaccines (100%), access to vaccination centers (93.3%), health-care professionals’ recommendations (85.5%), and education level (86.9%) as major determinants of vaccine uptake among health-care workers in Ilorin, Kwara State. Other factors included religious belief (99.3%) and family approval (97.6%). In conclusion, education, vaccine safety perception, access to vaccination centers, family approval, and health-care workers’ recommendations are key factors influencing behavioral changes toward COVID-19 vaccine uptake among health-care workers in Ilorin, Kwara State. The study recommends that public health agencies and the health ministry focus on these factors in policy formation to improve COVID-19 vaccine uptake in Kwara State and Nigeria as a whole.

Authors: Muhamya Horace , Ocan Johnson , Adyanga Akena Francis
Published: June 2024

Climate change is a global phenomenon of unprecedented consequence, engendering substantial scientific, political, and societal discourse. This literature review article offers an exploration of climate change perceptions and realities in the African context. It begins by establishing the unmistakable scientific consensus, with the Intergovernmental Panel on Climate Change (IPCC) serving as a primary authority. The review highlights robust evidence, including temperature trends, extreme weather events, and ecological impacts across the African continent, affirming climate change as an undeniable scientific phenomenon. However, the discourse surrounding climate change in Africa is not homogeneous. Dissenting arguments challenging climate change as a myth emphasize the variability in public perception, data limitations, and the complexities of attribution. These counterarguments reflect diverse perspectives, economic interests, and political inclinations, contributing to the multifaceted character of the climate change discussion. The implications of these findings are substantial, especially for a region highly susceptible to climate change impacts. Proactive measures for climate mitigation and adaptation are imperative to address the vulnerabilities experienced by communities, ecosystems, and economies. A multidisciplinary approach is underscored, recognizing climate change as an intricate challenge interwoven with economics, politics, and human behaviour. The diversity of voices in this discourse emphasizes the need for ongoing research, collaborative efforts, and an inclusive approach to policy formulation. In navigating the complex terrain of climate change, unwavering commitment to scientific rigor, transparency, and sustainable solutions is paramount. This literature review contributes to the ongoing dialogue, providing a basis for further inquiry and informed decision-making. It has the potential to guide future investigations, shape public policy, and elevate awareness regarding the critical significance of addressing climate change in the African context and, by extension, the entire world. The findings presented here are a testament to the indispensable role of rigorous scholarship in comprehending and confronting one of the most pressing challenges of our time
