Zora Neale Hurston's Recorder
Authors: Rivero Kristin
Published: December 2024

abstract: This article revisits the role of mediation in Zora Neale Hurston's fiction and anthropological research. Scholars have long recognized the tension between the intimacy and "constructedness" of her work, as well as the modernist sensibility of her facility with multiple media forms. Hurston does not simply deploy mediation as a representational strategy; she theorizes the mediation of the Black body as inextricable from the media forms of her age. In doing so, Hurston contributes to the production of emergent media in the modernist age by generating new forms of representational agency and subjectivity.

Y además 14 participantes (28%) disminuyeron o abandonaron la lactancia materna posterior a la recuperación. La principal causa de abandono fue por miedo al contagio del lactante. Conclusiones: La COVID-19 puede motivar a modificaciones en las prácticas de lactancia.
Balancing Sustainability and Resilience in Buildings: a Resilience Module for an Existing Sustinability Rating System
Authors:   , Felicioni Licia
Published: December 2024

The built environment is increasingly vulnerable to the frequent and severe hazards posed by climate change. The majority of existing buildings need to be more adequately equipped to withstand these threats, highlighting the need for adaptation strategies that enhance both resilience and sustainability for new and existing building stock. Green building rating systems, developed and adopted since the 1990s, provide a framework for measuring sustainability; however, they largely lack the integration of resilience principles, indicating a critical gap in implementation. A comprehensive literature review identified that sustainability and resilience in building design share common grounds, allowing for their potential coexistence to create more resilient and sustainable solutions. The primary objective of this PhD thesis is to develop a new Resilience Module, structured in a manner similar to existing building rating systems, and integrate it into the SBToolCZ framework, using this Czech national sustainability rating system as a case study. An extensive review of existing literature was conducted to identify recurring elements of sustainability and resilience in buildings, examining various sustainability and resilience rating systems. This informed the selection of relevant criteria and indicators for developing the Resilience Module. A weighting process was then performed, with input from a panel of experts, to determine the significance of each criterion. The Resilience Module was subsequently tested as a standalone system on three building case studies located in the Czech Republic, assessing its effectiveness in measuring and improving building resilience. Finally, the Resilience Module was integrated into the SBToolCZ rating system, with support from its development team, and tested in a building case study to compare the standard and integrated versions, demonstrating the feasibility and added value of the integration. The primary outcome of this research is a Resilience Module that can function independently as a tool for guiding designers toward more resilient projects while also being adaptable for incorporation into any green building rating system by integrating the criteria into existing categories. This work marks a significant advancement in incorporating resilience principles into building design, ensuring that both sustainability and resilience are considered, thereby enhancing the built environment's preparedness for future climate change-related hazards.

Authors:   , Zahradník David
Published: December 2024

Maintaining and controlling technical infrastructure presents complex challenges with substantial security and financial implications. This research investigates the potential of laser scanning, photogrammetry, thermal imaging, and deep learning (utilizing models such as CNN and U-NET) of asset inspection practices. The study underscores the effectiveness of laser scanning for internal geometric analysis of rotary kilns, which are prone to internal lining damage. By generating geometric data, laser scanning facilitates the planning of repairs for the kiln's inner lining, enhancing maintenance efficiency and reliability. Moreover, the research explores enhancing deep learning models for flat roof classification and leakage detection by integrating additional inputs derived from photogrammetric processing, such as elevation and slope data. This approach aims to improve leakage detection and the overall assessment of roof conditions. Additionally, the study delves into the use of texture rendering through a combination of laser scanning and photogrammetry for cooling tower inspections. This method enables the detection of surface damage, providing a analysis of the tower's condition. By leveraging these technologies, the research aims to take advantage of data from photogrammetric processing and use it for monitoring conditions of building objects and structures.

Authors: Wu Changyun , Han Liyang , Tan Huan
Published: December 2024

The adverse effects of antibiotics on ecological health of aquatic environments is increasingly a social and scientific concern. Here we investigated the occurrence, distribution, and risk assessment of residual antibiotics in the main drinking water source (Baitiao River and Xuyan River) of Chengdu, China. Five commonly used antibiotics including sulfamethoxazole, tetracycline, roxithromycin, erythromycin, and chloramphenicol were tested in the two rivers with concentration ranging from less than limits of quantification to 3.62 ng L-1. Among them, tetracycline was persistent in surface water and exhibited no significant differences along the flow direction of the two rivers. Compared to other rivers or surface waters in the world, the concentrations of the five antibiotics in present rivers were mainly below average levels. All the risk quotients of detected antibiotics in the rivers were lower than 0.001, suggesting that they were at a low level of ecological risk across trophic levels of aquatic organisms.
Sharing vulnerability: A duoethnographic enquiry into the development of digital competencies at a South African university
Authors: Andrianatos Kristien , Morelli Janelize
Published: December 2024

The duoethnographic enquiry discussed in this article grapples, in a dialogical way, with our experiences of professional learning while seeking to increase our digital competencies. The process involved happened while we were learning to use Mentimeter, an interactive presentation software. The purpose of this duoethnographic enquiery is not to provide solutions or shortcuts through a sharing of our professional learning journey. Rather we share our experiences in the hope that other higher education (HE) educators will join the conversation and reflect on their digital competencies journey. In this paper, we first present the background followed by a brief discussion of the HeDiCom framework of HE educators’ digital competencies. Then we briefly discuss duoethnography as a method. Our three main findings are presented as conversations, followed by a discussion in which we weave the insights from our conversations into a critical reflection on the applicability of the HeDiCom framework.
Ageism and gatekeeping: My experiences as an early career academic at a historically black university in South Africa
Authors: Maluleka Paul
Published: December 2024

In 2019, senior black academics wrote about their experiences as members of faculty at historically white universities (see Khunou, et al., 2019). These experiences were reflective of the authors’ encounters with the legacies of colonialism, apartheid, and neoliberal capitalism. However, often experiences of academics from historically black universities (HBUs), especially early career academics (ECA), are marginalised and excluded. Using intersectionality and Nat Nakasa’s ‘native of nowhere’ as theoretical lenses and an autoethnographic reflexivity approach as the methodological approach, I narrate my encounters with ageism and gatekeeping at a HBU as a New Generation of Academics Programme academic. I argue that the intersectionality between ageism and gatekeeping made me feel like a native of nowhere. I equally conclude that moving forward there is a need to foster a sense of belonging among ECAs through enacting decolonial love. This requires that senior (black) academics not to perpetuate similar violent experiences they endured. This way, ECAs can become natives of somewhere within the university.

Published: December 2024

This research explores the significance of financial inclusion for the performance of micro, small, and medium enterprises (MSMEs). Employing a mixed-method approach comprising qualitative and quantitative analyses, including descriptive and structural equation modeling analyses, the study gathers primary data through distributed questionnaires to MSMEs. The validity of the data is assessed through validity, reliability, and goodness-of-fit tests. Findings from previous research indicate a significant positive impact of financial inclusion on the performance of MSMEs, suggesting a strong relationship between financial inclusion and MSME performance. This correlation implies that increased financial inclusion enhances MSME performance, underscoring the crucial role of financial inclusion in fostering the growth and success of micro and small enterprises. The research informs government efforts to boost financial inclusion, enhancing MSME performance. Improved access to financial institutions in Indonesia for MSMEs is expected to lead to enhanced sales growth, customer expansion, and increased profitability, ultimately benefiting the broader economy.

Published: December 2024

Business sustainability is an essential issue in the age of globalization, and it reinforces the value of quality information in the strategic decision-making process. Management accounting information systems are alleged to have a strategic role in producing quality accounting information, which is ultimately influenced by managerial considerations and the level of workforce expertise. This study seeks to identify the substances that influence the efficacy of management accounting information systems. Quantitative analysis was performed to find out the association between the variables tested. Questionnaires have been sent to 132 managerial accountants from Indonesian state-owned businesses. The method of selection used consisted of simple random sampling, and the resultant sample size for this study was 72 participants. The data were analyzed using Structural Equation Modeling (SEM) on Lisrel software version 8.5. The investigation's findings reveal that skill and departmentalization are substantially related to the effectiveness of management accounting information systems. Nevertheless, this needs to be reinforced by business strategy elements. The present investigation revealed that the competencies and tasks performed by departmentalized business units play a substantial part in the effectiveness of establishing a management accounting information system in Indonesian state-owned firms.

Published: December 2024

The higher education sector is embroiled in a continuous digital transformation process, resulting in a significant need for an innovative business model need for an innovative business model. Private universities are required to survive amidst competition in this digital era. The need for an innovative business model is reinforced by the fact that Student Satisfaction (SS) still needs to improve at Private Universities in West Java, Indonesia. This research develops a Smart University Image (SUI) as a novelty in a new business model to increase SS. In addition, SUI was developed because brand image theory was deemed insufficient and inconsistent from a semantic or functional standpoint when applied to a smart university (SU). The SUI dimensions developed are Cognitive, Conative, Emotive, and Collaborative. This research also aims to develop and test the SUI model synthesized from Relationship Marketing. A quantitative method is used in this research using proportional purposive sampling data collection techniques. The questionnaire distribution was based on the criteria of respondents who were second and third-year students at private universities (PU) in West Java, Indonesia, and were classified as SU. The data analysis used Structural Equation Modeling (SEM), partial model test, and Sobel test to determine the strength of the mediation role in this research model. The findings of this research state that the SUI relationship significantly affected SS, which means it is appropriate to be applied to new business models in the higher education sector. The recommendations from this research findings are that private universities need to develop business models that apply high technology to create student engagement and SS in the framework of a smart university.

Blurred lines of participation: nexus analytical tools for reflecting on the roles of researchers and participants in change-oriented research projects
Authors: Tumelius Riikka , Legutko Justyna , Intke-Hernandez Minna , Vorobeva Polina
Published: December 2024

This article discusses nexus analysis (NA) as a research strategy that provides specific tools for reflecting on the roles of researchers and participants in participatory research. While many research traditions use participatory methods and problematise what it means to participate in research, thus far the potential of nexus analytical concepts as tools to mediate such a reflection has not been discussed explicitly. In order to illustrate how NA promotes such reflections, we draw on four linguistic projects in multilingual settings that deal with (1) preservice teachers’ learning to design for language learning in hybrid environments on a university course, (2) plurilingual and collaborative teaching approaches to writing in language classrooms in secondary schools, (3) language socialisation of migrant mothers, and (4) family language policy in single-parent families. With this article, we demonstrate how the nexus analytical conceptual tools of ‘zone of identification’, ‘historical body’ and ‘interaction order’ facilitate reflection upon the researcher’s participatory engagement in various stages of the research process. We show that the lines between the roles of researchers and participants are blurry, in particular in research projects that focus on introducing social change. Additionally, we highlight the importance of reflecting on power relations between researchers and participants and how control over project direction and decisions can impact the representation and involvement of community members.

Authors: Abdulkhaliq Shadan , A. Jalal Jalal
Published: December 2024

Background and objective: GATA3, an emerging immunohistochemical marker, is a zinc finger transcription factor that is expressed in normal urothelial epithelium and its corresponding neoplasms, and it has been recognized as a reliable urothelial related immunohistochemical marker. This study aimed to detect the frequency of GATA3 expression in urothelial carcinoma of urinary bladder and determine its association with some clinicopathologic parameters.

Methods: Seventy-nine formalin fixed paraffin embedded blocks of urothelial carcinoma cases were randomly selected from a private laboratory in Erbil city during October 2019 to October 2021. In this study, GATA3, a Rabbit monoclonal antibody was applied on urothelial carcinoma cases and its expression was assessed.

Results: GATA3 was expressed in 94.9% of the study cases. It was expressed in all non-invasive and low-grade urothelial carcinoma cases and 97.1% of papillary urothelial carcinoma cases, while it down-expressed in high-grade, invasive and non-papillary urothelial carcinoma cases. A significant association was noted between GATA3 expression and tumor pattern (P = 0.034), while no significant association was noted between GATA3 expression and other clinicopathologic parameters like age, gender, tumor grade, lympho-vascular invasion and tumor stage.

Conclusion: GATA3 is a useful diagnostic immunohistochemical marker for urothelial carcinoma, as this marker was expressed in 94.9% of urothelial carcinoma cases with a significant association with tumor pattern. Further studies are required to evaluate GATA3 expression in association with urothelial cancer progression and metastasis.

Published: December 2024

Background and objective: Since the beginning of the medical practice, headache was considered both a therapeutic and a diagnostic challenge. According to the ranking that was made by the global burden of diseases collaborative network for causes of disabilities, headache was considered the fourth for both males and females. The aim of the study was to evaluate the findings of MRI among headache patients.

Methods: A cross-sectional study was conducted from 1st of Nov. 2021 till the 1stof June 2022. A convenient sample was collected from referred patients to outpatient clinic in Rizgary Teaching Hospital. The cases were diagnosed by a specialist in internal medicine and then referred for further MRI evaluation. The data analyzed using IBM SPSS (statistical package of social science) version 25. The data was summarized by descriptive statistics. The measures of central tendency and dispersion were calculated. The mean of age differences was calculated by t-test. The associations between categorical variables were found by Chi-square test. The P value was considered significant if it was ≤ 0.05.

Results: Out of 150 patients, 70% were females and only 30% were males with male to female ratio of. 0.43:1.73.3% of females in primary group had normal MRI findings and 84.4% of males had abnormal findings in the secondary group. The difference was statistically significant (P-value <0.001). The mean age ± SD for males was 45.2 ± 9.3 and the mean age for females was 37± 9.8. The difference between means was significant (P = 0.018). In MRI findings 56% (84 out of 150) of patients were normal, followed by sinusitis (28%), (3.3%) cerebral tumor,0.6% had pituitary mass and 0.6% diagnosed as meningitis.

Conclusion: The low rate of positive findings in our study supports the need for an evidence-based guideline for neuroimaging in this health care setting. Future studies are recommended to investigate other physicians’ reasons for using neuroimaging techniques as a routine investigation for headache patients.

This study aimed to investigate the association between toxoplasmosis and rheumatoid arthritis among patients, besides, to confirm the role of Toxoplasma gondii in the enhancement and modulation of autoimmune diseases such as rheumatoid arthritis.

Methods: A cross-sectional study was implemented from August 2021 to February 2022, in which blood samples were taken conveniently from a total of 180 patients from both genders and different ages (15-60 years). These patients attended Zakho General Hospital and some private clinics suffering from symptoms related to rheumatoid arthritis. All samples were tested for Toxoplasma gondii immunoglobulins G and M (IgG, IgM) antibodies, C- reactive proteins (CRP), rheumatoid factor (RF), and erythrocyte sedimentation rate (ESR).

Results: The total seropositivity of anti-Toxoplasma gondii IgG and IgM Abs using ELISA were 13.9% and 3.9%, respectively. Furthermore, the highest rate (16.4%) of IgGAbs was recorded among the male group, while, the highest rate (4.8%) of IgMAbs, was recorded among the female group. Furthermore, the highest rate of IgG, and IgM Abs were recorded among the age group 46-60 in both genders (20%, 5.7% respectively). In addition, the statistical analysis demonstrated the presence of significant relationship between IgG Abs with CRP and RF test results (P = 0.027, 0.039 respectively). Whereas, concerning ESR only seropositive IgM Abs results were statistically significant (P = 0.049).

Conclusion: Toxoplasmosis may influence the immune system and act as a contributing factor in the exacerbation of autoimmune illnesses, including rheumatoid arthritis. Subsequent investigations will be essential to delineate the risks of T. gondii within the human population.
Education and Vulnerability. On the Historiographical Analysis of the German Educational Discourse on Punishment in the “Short” 19th Century
Authors: Heinze Carsten
Published: December 2024

Although the contemporary educational discourses in the 19th century considered educational punishment one of the most effective means of education, and a though it was frequently used in the educational practice, its history in the Germanspeaking countries has been only rudimentarily researched. This is even more astonishing as the history of educational punishment must be understood as a history of violent educational practices. In this article, the question shall be pursued of how a historiography of educational punishment in the 19th century could be theoretically and methodologically based. The research is guided by the thesis that educational punishment must be understood in the sense of exploiting the child’s vulnerability.
Reflexiones sobre lo fáustico en Blumenberg
Authors: Bartoli Fabio
Published: December 2024

Por medio del estudio de la última escena del Fausto de Goethe, se tratará de complementar la lectura blumenberguiana presente en el ensayo “La crisis de lo fáustico en la obra de Franz Kafka” con elementos presentes en el texto goethiano y que son fundamentales en el proyecto metaforológico de Blumenberg. En nuestro criterio, el elemento técnico no es la única clave de lectura de aquella escena, ya que allí se pueden detectar otros elementos blumenberguianos. Por ejemplo, se puede identificar la presencia del tema de la inquietud (Sorge), la metáfora de la luz y, finalmente, una variación de la metáfora del naufragio y de la dialéctica entre tierra y mar.
Algunos tiempos de Zambrano: gracia y melancolía

En la primera parte del artículo, presento el proyecto de ontología temporal que María Zambrano desarrolló durante más de 20 años, señalando la importancia central que adquiere en su obra. En la segunda parte, analizo las propiedades de dos fenómenos que son ejemplo de dos estructuras del tiempo que conjuga Zambrano. Considero la melancolía como un fenómeno de la continuidad temporal y exponente de lo que es la percepción en la vigilia de la pretemporalidad; e interpreto la gracia como un fenómeno de la discontinuidad temporal y el modo excelso de la supratemporalidad o tiempo creador.
Transhumanismo: una versión de la «Transfinitud» garcíabaquiana
Authors: González Ramírez Yulfren Jhonattan
Published: December 2024

El transhumanismo es una corriente filosófica que tiene como meta la trascendencia de la especie humana. La transfinitud es la tendencia que tiene el hombre por superar sus límites naturales. El transhumanismo difunde la creencia de que es posible prolongar la existencia humana a través de la aplicación de medios tecnológicos. Aquí se muestra que la transfinitud sirve —como base teórica— para comprender la tendencia del hombre a la trascendencia, posicionándose como una versión «previa» del transhumanismo. Esto convierte a la filosofía garcíabaquiana en precursora del transhumanismo o biomejora humana.
ENGINEERING METHOD FOR CALCULATING ISOGRID COMPOSITE REINFORCEMENT IN COMBINED TOROIDAL TANKS
Authors: Lipovkyi V. I.
Published: December 2024

The article focuses on determining the parameters of isogrid reinforcement for a combined toroidal tank. It addresses the need to implement a simplified model for a method that can be used for preliminary tank design. This approach allows for analyzing the impact of geometric parameters of isogrid reinforcement and the effect of the mechanical characteristics of the composite reinforcement tape on the mass of the combined toroidal shell. The research is based on developing a simplified model in which the composite reinforcement operates under linear stress conditions, while the liner functions in the nonlinear deformation zone. Compatibility conditions for deformation between the liner and the composite are met, and the composite's performance is assessed using the strain-based strength theory.
An algorithm for calculating of the proposed method has been developed. Using this algorithm, combined toroidal tanks with isogrid reinforcement were calculated. A comparison was made with existing metal tanks used in the first and second stages of the European Ariane launch vehicle and water tanks of the Indian GSLV Mk3 and PSLV launch vehicles. The results show that application of isogrid reinforcement can reduce tank mass by up to 50%. The proposed method was also compared with an existing one for assessing the mass of a combined tank with continuous longitudinal-transverse winding of composite tape.
This research expands the set of engineering methods for designing combined toroidal tanks with isogrid composite reinforcement. The study is limited to analyzing the geometric parameters of isogrid reinforcement and does not address optimizing the tank's design parameters. The work aims to use the initial approximation results in creating a model for finite element analysis. Future studies may focus on application of the method for parametric modeling of the shell via the finite element method and conducting numerical experiments to determine a viable minimal-mass structure.

Ultrasonography is a reliable imaging technique for the accurate diagnosis and evaluation of musculoskel- etal disorders. Recent developments in ultrasound technology have significantly increased image resolu- tion, making it possible to see anatomical features at almost microscopic dimensions. Current standards for standardized shoulder ultrasonography mostly depend on outdated machine types and configurations that may not fully utilize these high-resolution imaging capabilities. In this article, we give a clear and com- prehensive introduction to high-resolution shoulder sonography, using histological and anatomical images from cadavers for comparison. Images collected using contemporary technology are shown, and interna- tional standard practices are considered. The examination and normal results are presented in a methodical manner, beginning posteriorly, moving frontally, then more anteriorly, and concluding with a lateral and optional axillary examination. This article focuses on the anterior and lateral shoulder.
Discourses of Heritagization in East-Central Europe
Authors: Eitler Ágnes , Ament-Kovács Bence
Published: December 2024

The making of heritage is a complex contemporary process that permeates society from the normative contexts of the global as well as national level to local communities. It enters extremely diverse sites, since it is part of both rural and urban life-worlds, and it is present in the institutional space of museums as well. Cultural elements that have been detached from their former contexts and made into heritage are no less diverse. The symbolic valorization of different historical periods depends on the regional and local contexts of heritage-making. The prestige (acceptance or rejection) and meanings of the legacy of certain periods, relationship to tradition, as well as the ways in which ‘authenticity’ is interpreted are products of a constant re-defining process steered by various social actors, such as members of local communities, cultural brokers, and experts. These positions often represent intertwining roles (researcher, expert, mediator, active or passive local actors) that are difficult to distinguish from one another in the various situations in which heritage-making can be researched empirically.

Current changes in the socio-economic situation in Russia have a significant impact on all sectors of the economy, including the banking sector. Competition among banks is intensifying, as each financial institution seeks to attract the maximum number of clients, expand its market and increase profits. The key element in achieving these goals is the promotion of new and modernization of existing banking products. For the successful implementation of a marketing strategy, it is necessary to take into account the competitive position of the company in the market and select the appropriate tools. The set of marketing tools aimed at influencing market participants includes integrated marketing communications. Philip Kotler, a professor of international marketing, proposed a set of tools used by modern marketers to promote goods. The main tools for promoting banking products include advertising, direct marketing, personal selling, public relations and sales promotion. Advertising plays an important role in informing customers about new products and the bank's activities. Direct marketing allows banks to meet customer needs through non-personal contacts such as telephone or mail, providing instant feedback. Personal selling involves direct communication with customers, which increases the effectiveness of promotion, especially with a wide branch network. Public relations help maintain a positive image of the bank through interaction with the media, customers and participation in social projects. Sales promotion, including discounts and preferential rates, briefly encourages the purchase of products. Information technologies, such as Internet banking and mobile applications, have significantly changed bank marketing, providing customers with convenient and mobile ways to interact with the bank. The development of technologies such as marketplaces contributes to the availability of financial services and the optimization of services. The effectiveness of marketing strategies depends on the correct choice of tools and taking into account the specifics of the internal and external environment of the bank, as well as the general economic situation.

In the article the authors consider the problem of CO2-corrosion of carbon and low-alloy steels under elevated temperature. The problem of CO2-corrosion of steels is one of the most important in the operation of pipeline systems. When involving viscous and super-viscous oils in the development for the extraction of which steam injection technologies are used, usage of corrosion inhibitors for elevated temperature conditions is actual. The article presents results of studies of the effectiveness of corrosion inhibitors in pre-calculated maximum cost-effective dosages on a water-oil emulsion model and on a formation water model at temperatures of 60–80 °C and 110 °C under CO2-corrosion. It has been shown that the flow regime of the water-emulsion mixture significantly affects the corrosion rate. Water-soluble corrosion inhibitors reduce the corrosion rate in the studied temperature range, but do not provide the required corrosion rate level due to the low adsorption capacity in the tested dosages.

The paper deals with the problem of determining the stress-strain state of a vertical steel cylindrical tank wall in the presence of uniform roll. It is indicated that one of the factors influencing the general stress-strain state of the tank wall, which is a thin shell according to the basic laws of structural mechanics, is the presence or absence of settlements of the bases and foundations of the structural elements of the tank. The roll occupies an intermediate value in the degree of danger between uniform and non-uniform types of settlement. The article uses classical methods of structural mechanics, existing analytical solutions, as well as numerical methods, in particular, the finite element method with implementation in the ANSYS software package. The developed numerical model of the RVSP-20000 tank with application of the finite element method in ANSYS allowed to determine displacements, deformations and stresses in the wall structures of the tank having a roll. The results obtained by the authors show that the roll of the tank, in which there is no detachment of the rim from the annular foundation, practically does not affect the overall stress-strain state of the tank. However, the authors have obtained a valuable dependence for practical application, which allows identifying the presence or absence of areas of the outer contour of the bottom with non-uniform settlement, considered by the authors as a rather dangerous phenomenon.
IDENTIFICATION OF CAUSES FOR DECLINE IN OIL PRODUCTION DUE TO INCREASED WATER CUT IN MATURE FIELDS
Authors: Populova T.P.
Published: December 2024

The article is focused on identifying the causes of reduced oil production rates due to increased water cut at AB1(1-2) object of a mature field. It classifies and analyzes the existing methods for determining the causes of rising water cut, including instrumental, hydrodynamic and field-analytical approaches. The study distinguishes potentially reversible and irreversible water cut losses, providing real examples to illustrate the current challenges in the oil production industry. The paper underscores the necessity of developing a machine learning-based tool to enhance process efficiency and presents a development plan for such instrumentation. The development of tools for determining the causes of flooding of oil wells using integrated analytical methods and machine learning technologies is an important step towards improving the efficiency of oil production. Combining various approaches in a single algorithm will significantly optimize the time for decisionmaking and reduce losses in oil production. The implementation of such technology will be the key to successfully solving the problem of determining the causes of flooding. The key element in creating an effective toolkit will be the implementation of machine learning technologies. Training on historical data will allow the algorithm to identify complex dependencies and patterns that may not be obvious in traditional analysis. Machine learning models will be able to adapt to changes in data, which will make them more flexible and accurate in predicting the causes of flooding. The use of machine learning will also allow the creation of predictive models that will not only determine the current causes of flooding, but also predict possible problems in the future. This will make it possible to take preventive measures and optimize the production process.

Carbon dioxide injection to enhance oil recovery by improving the physical and chemical properties of the reservoir environment is one of the effective methods of increasing oil production, and every year it is more and more actively used in the oil industry around the world. Carbon dioxide entering the formation increases the pressure and improves the rheological properties of formation fluids, which contributes to the further oil displacement from the pore space. An important advantage of carbon dioxide injection for enhanced oil recovery is the possibility of its geological storage (utilization) in reservoir rocks, which meets the goals of decarbonization – achieving carbon neutrality of the global and Russian economy. The scientific article presents the methodology of objects-polygon selection for carbon dioxide injection to enhance oil recovery. The main objective of the research was to summarize and systematize the geological and physical characteristics of reservoir systems represented by carbonate reservoirs of the fields of the Volga-Ural Oil and Gas Province (deposits of Bashkortostan, Tatarstan and Perm Krai) and their subsequent clustering according to a set of attributive geological and geophysical characteristics using complex geological and statistical analysis. Within the framework of the study the object clustering procedure was performed using the principal component method (PCM), on the basis of which five groups of productive objects with characteristic features were identified. Various machine learning algorithms and types of artificial neural networks (ANN) were applied to process a large volume of specialized data, which significantly improved the accuracy of analysis and the quality of data classification. Four key geological and physical parameters were identified as a result of comprehensive neural network analysis. Clustering of development objects of carbonate reservoirs of oil fields of Perm Krai, Republic of Bashkortostan and Republic of Tatarstan, as well as their subsequent identification using PCM and ANN allowed to establish a set of criteria ensuring the success of carbon dioxide injection technology. In each group a typical object-analog, which satisfies the applicability criteria of the carbon dioxide injection method, was selected. As a result of the research, a database was formed for the operational selection of objects-analogs for carbon dioxide injection to enhance oil recovery at depleted oil fields.
