Masala and Misogyny: A Qualitative Study of South Asian American Women’s Ethnic-Racial Identity
Authors: Wadhwa Hena K. , Daulat Neesha , O’Brien Christine
Published: February 2025

The present study explores the lived experiences of South Asian American women and what elements shape their ethnic-racial identity (ERI). Particularly, it discovers what push and pull factors encourage South Asian American women to lean towards or away from their ERI. This qualitative study used an open-ended survey to gather responses from 38 South Asian American women. Our qualitative study findings suggest that there are diverse elements of South Asian culture that encourage South Asian American women to embrace and/or reject parts of their ERI. Data analysis revealed that cultural aspects are impactful elements (e.g., food, music, community) that sustain South Asian American women’s connection with their ERI. Alternatively, the presence of patriarchy, misogyny, and feeling “othered” are factors that disengage South Asian American women from their ERI. Findings from this study contribute to the ongoing and vital expansion of the discussion of ERI and tap into the nuances of South Asian American women’s ERI.

Published: February 2025

The study examined the effects of teaching activities, including Kazakh Epics and mythopoetic images, on the participants’ national value achievements and attitudes towards the course in literature courses in Kazakhstan. This study used a quasi-experimental design with a pre-test, post-test, and a control group. The dependent variables were the national value achievement scale and literature course attitudes. The independent variable was the teaching activities based on Kazakh Epics and mythopoetic images in the second-year courses of the literature department of a university in Almaty. The national value achievement and attitude scales were used to collect data, which were analyzed with covariance analysis. The results showed a statistically significant improvement in students’ national value achievement scores in the experimental group exposed to Kazakh Epics and mythopoetic images. The study’s findings pave the way for recommendations for integrating culturally meaningful narratives into education. First, culturally rich content such as Kazakh Epics should be included in Kazakhstan’s literature departments’ curriculum, and policymakers and curriculum developers should prioritize the creation of teaching materials that emphasize these epics’ historical, ethical, and literary aspects. Second, the accessibility of these materials should be increased, and their compatibility with contemporary educational goals should be ensured. Third, teacher training programs should be reorganized to emphasize culturally sensitive pedagogical approaches. Though this study was localized, the research results can be applied to education systems in different geographies to develop cultural identity and values.

Published: February 2025

The quality of courses plays a significant role in shaping effective future educators, particularly in mathematics education, where innovative assessment and teaching methods are crucial. This study investigates the experiences and satisfaction of future mathematics teachers enrolled in a course on criteria-based assessment (CBA) techniques, delivered using a project-based learning (PjBL) approach. A total of 98 participants from a university in Kazakhstan provided survey data that were analyzed using cluster analyses. The k-means algorithm identified three distinct clusters of participants: “less engaged or satisfied,” “moderately satisfied,” and “highly engaged and satisfied.” The optimal number of clusters was determined using the elbow method, and 3D scatter plots provided a visual representation of the data patterns. Additional analyses examined gender, prior experience with assessment techniques, and prior experience with in PjBL, highlighting significant variations in satisfaction and engagement levels across these factors. Results showed that students with intermediate knowledge of assessment techniques and prior PjBL experience were more likely to belong to the highly satisfied cluster. Gender distribution indicated a slight tendency for female students to benefit more from the CBA course. Key challenges included complex tasks such as reliability calculations, which impacted the less engaged group more significantly. Findings highlight the importance of aligning course design with learner needs, offering structured support, and integrating foundational training in CBA and PjBL methodologies. This study provides actionable recommendations for enhancing teacher education programs and improving the implementation of innovative teaching and assessment strategies.

Published: February 2025

Wastewater treatment is a critical environmental challenge exacerbated by rapid industrialization, urbanization, and population growth. Conventional treatment methods, including physical, chemical, and biological processes, often fail to efficiently remove emerging contaminants such as micro-pollutants, heavy metals, pharmaceutical residues, and persistent organic compounds. These inadequacies highlight the urgent need for advanced, sustainable, and cost-effective solutions. Bio-nanotechnology, which synergistically integrates biological systems with nanomaterials, presents a promising approach to enhancing wastewater treatment efficiency. This paper explores various bio-nanotechnology applications, including the use of nanomaterial-enhanced microbial degradation, biofunctionalized nanomaterials for selective contaminant removal, and nano-bioremediation techniques that leverage the unique properties of nanoparticles and biocatalysts. Nanomaterials such as metal oxide nanoparticles, carbon-based nanostructures, and bio-inspired nanocomposites have demonstrated significant potential in improving contaminant adsorption, catalytic degradation, and microbial activity.

Authors: Hassan Ali
Published: February 2025

The convergence of quantum computing and artificial intelligence (AI) presents a paradigm shift in healthcare, revolutionizing complex biological simulations, genomic data processing, and drug discovery innovations. Traditional computational methods, despite their advancements, often struggle with the sheer scale and complexity of biological data, limiting the speed and accuracy of medical breakthroughs. Quantum computing, with its ability to process vast datasets exponentially faster than classical computers, coupled with AI's predictive capabilities, offers a transformative solution for accelerating biomedical research and clinical applications. This paper explores quantum machine learning’s role in optimizing AI-driven molecular dynamics simulations for drug discovery. By leveraging quantum-enhanced algorithms, researchers can rapidly model molecular interactions, analyze drug-receptor binding affinities, and predict pharmacokinetics with unprecedented precision. Additionally, we examine quantum-assisted deep learning models for deciphering intricate biological mechanisms such as protein folding, epigenetic modifications, and metabolic pathway interactions, enabling more accurate predictions of disease progression and therapeutic targets. Furthermore, the integration of AI-quantum hybrid models in clinical diagnostics and imaging analytics is redefining personalized medicine. Quantum-enhanced deep learning facilitates high-resolution medical imaging, real-time anomaly detection, and optimized radiomic feature extraction, leading to early and more accurate disease diagnosis. In genomics, quantum computing significantly accelerates whole-genome sequencing and mutation analysis, paving the way for tailored treatment strategies based on an individual's genetic profile. Despite its promise, challenges such as quantum hardware limitations, data coherence issues, and ethical considerations must be addressed to ensure the practical implementation of quantum-AI healthcare solutions.

A large proportion of global gas consumption is derived from naturally occurring sources that are not readily available and accessible by a common man in the street. This has continued to pose serious challenges to researchers in developing suitable alternatives to the naturally occurring gas supply source. A notable problem associated with the use of gas from natural sources is that it contributes to global warming as a result of the release into the environment of the related by-products from its exploration, production, and usage. The cow dung used in this study consists of 6 % moisture, 15 ash, 96 total solids, 80 % volatile solids, 8.1 pH, and 20 % fixed solids. The result of the characterization revealed 5 % moisture, 5.2 % ash, 95 % total solid, 89 % volatile solid, 6.6 pH, and 11 % fixed solid. The pH of the mixture of PCCD is 7.4 and PCCDBC is 7.6 which is an improvement to the individual pH of cattle dung and pineapple crown. Hence, both cow dung and pineapple crowns are suitable for biogas production.

Published: February 2025

Pigmentogenic lichen planus (PPL) is a rare variant of cutaneous lichen planus characterized by hyperpigmented lesions on the tegument. This dermatosis has rarely been described in association with other diseases. The aim of our study is to describe the epidemiological profile and pathological associations of PPL in a prospective study conducted in our dermatology department in the university hospital of Marrakech, over a period of 11 months, focusing on histologically confirmed cases of PPL. We identified 65 histologically confirmed cases of PPL, with phototypes ranging from 3 to 5. The sex ratio was M/F = 0.3. The mean age was 43.5 years, with a mean duration of progression of 5 years. 32 patients had phototyped IV, 21 patients had phototyped V and 12 patients had phototyped III. There were two similar cases in the family. Triggering factors, in descending order, were stress followed by scrubbing in the Moorish bath, then sun exposure without photoprotection, drugs such as estrogens and progestogens, insulin and metformin, then the application of oils such as lavender oil, orange oil and olive oil, pregnancy, then finally the use of henna-based preparations, and coffee masks. Pruritus was present in 38 patients, then 23 patients reported aesthetic discomfort and 4 reported a burning sensation. Pathological associations were dominated by frontal fibrosing alopecia, depression, type 2 diabetes, viral hepatitis B, lichen planus pilaris, hypothyroidism and Crohn's disease.

Chicken meat itself has a high nutritional content of protein and energy. STAT5a is an important protein in the Janus Kinase-Signal Transducer and Activator of Transcription (JAK-STAT) signal pathway. This is particularly relevant given the growing global market demand for healthy, safe, and antibiotic-free chicken meat. By understanding how STAT5a affects total leukocytes, differential leukocytes, and erythrocyte indices this study is expected to make an important contribution in developing new strategies to improve the health and productivity of broiler chickens. This study was an experimental study using a complete randomized design with The Post-test Only Control Group Design which consisted of five experimental groups (treatments) using broiler chicken as a test animal. The administration of the synthetic protein STAT 5a can increase the total blood leukocytes of broiler chickens, but still within normal limits. The administration of the synthetic protein STAT 5a can increase the heterophyil of broiler chickens, but still within normal limits. The administration of the synthetic protein STAT 5a can increase broiler chicken lymphocytes, but still within normal limits. The administration of the synthetic protein STAT 5a can increase the monocyte of broiler chickens, but still within normal limits. The administration of STAT-5a proteins at doses of 3.5%, 7% and 14% increased the Mean Corpuscular Volume (MCV) value and the dose of 3.5% was optimal. The administration of the 3.5% dose of STAT-5a protein increases the mean corpuscular hemoglobin (MCH) value and is the optimal dose. The administration of the 3.5% dose of STAT-5a protein increases the mean corpuscular hemoglobin concentration (MCHC) value and is the optimal dose.

Authors: Kumbha Ram Mahala  , Amar Chand Kumawat
Published: February 2025

Natural selection and processes of evolution have influenced the beneficial effects of natural products over hundreds of thousands of years, giving them a high degree of structural variety and distinctive pharmacological or biological activity. Natural products have therefore been used to cure illnesses in both traditional and modern medicine. Nowadays, natural materials are frequently utilised as a basis for medication development, with synthetic alterations made to aid in decreasing adverse effects and boosting absorption. In addition to medicine, natural products and their derivatives are frequently employed as food additives, such as herbs and spices, antibacterial agents, and antioxidants, to preserve the durability and quality of food. Bioactive compounds such as phenolic acids, flavonoids, anthocyanins, stilbenes, and lipids are abundant in grapes, mangoes, berries, and pineapple peels. These are the substances that give fruits and products made from them their health advantages. They are widely used in the food and nutraceutical industries and have anti-inflammatory, anti-carcinogenic, anti-microbial, and antioxidant properties. Utilising grape extracts that are high in these bioactive components has been connected with a lower prevalence of cardiovascular disease and its primary risk factors, such as hypertension, a medical condition that has a high global death rate. The citrus fruits are also a rich source of poly-methoxylated flavones (PMFs), a special type of bioactive flavonoid. Furthermore, because of its strong antibacterial, flavouring, and antioxidant qualities, citrus essential oil, which is abundant in limonoids and terpenes, is a valuable commodity from a commercial standpoint. The antioxidant capacities of pineapple peel extracts and these polyphenolic compounds were determined using (2,2-diphenyl-1-picrylhydrazyl) DPPH. The positive health impacts of polyphenols derived from berries and their potential use as a treatment for illnesses linked to the gut microbiota, such as cancer and inflammation. According to these findings, berries' polyphenols are a promising source of bioactive substances that can alter the gut microbiota and hence control cancer and related metabolic disorders.
Algorithmic bias, data ethics, and governance: Ensuring fairness, transparency and compliance in AI-powered business analytics applications
Authors: Julien Kiesse Bahangulu  , Louis Owusu-Berko
Published: February 2025

The widespread adoption of AI-powered business analytics applications has revolutionized decision-making, yet it has also introduced significant challenges related to algorithmic bias, data ethics, and governance. As organizations increasingly rely on machine learning and big data analytics for customer profiling, credit scoring, hiring decisions, and predictive analytics, concerns about fairness, transparency, and compliance have intensified. Algorithmic biases—often stemming from biased training data, flawed model assumptions, and insufficient diversity in datasets—can result in discriminatory outcomes, reinforcing societal inequalities and reputational risks for businesses. To address these concerns, robust data ethics frameworks must be integrated into AI governance strategies. Ethical AI principles emphasize accountability, explainability, and bias mitigation techniques, ensuring that decision-making algorithms are transparent and justifiable. Organizations must implement bias detection methods, fairness-aware machine learning models, and continuous audits to minimize unintended consequences. Additionally, regulatory frameworks such as GDPR, CCPA, and AI-specific compliance laws necessitate stringent governance practices to protect consumer rights and data privacy. Beyond compliance, fostering public trust in AI-powered analytics requires organizations to adopt ethical data stewardship, ensuring that AI models align with corporate social responsibility (CSR) initiatives and stakeholder expectations. The intersection of data ethics, algorithmic accountability, and regulatory compliance presents both challenges and opportunities for businesses seeking to leverage AI responsibly. This paper examines key strategies for mitigating algorithmic bias, establishing ethical AI governance models, and ensuring fairness in data-driven business applications, providing a roadmap for organizations to enhance transparency, compliance, and equitable AI adoption.
Journalistic objectivity in the Kurdistan region of Iraq: examining the relationship between journalists and politicians

Published: February 2025

This study examines the shifting dynamics between journalists and politicians in the Kurdistan Region of Iraq, focusing on the nature of their interactions and the implications for press freedom. Additionally, it explores the influence of Kurdish digital media on journalistic objectivity. Primary data were gathered through interviews with seven journalists and two media observers. The findings indicate a transformation in the journalist-politician relationship, evolving from a traditional alliance to a more strategic partnership. While this partnership has, in some cases, facilitated access to reliable information and countered misinformation, it has also compromised journalistic objectivity and professional ethics. The study highlights the persistent role of political influence as a critical factor shaping press freedom, given that many Kurdish media outlets, particularly digital platforms, depend on political affiliations for their survival. The impact of the journalist-politician relationship has been twofold: at times fostering the dissemination of accurate information, while at other times reinforcing misinformation and distorting facts, thereby undermining professional integrity. This alliance has also contributed to violations of journalistic standards, including defamation, ideological or religious offenses, incitement to criminal or terrorist activities, copyright infringements, breaches of privacy, and threats to social security and cultural traditions. The study further underscores the extensive political dominance over freedom of expression and the press in the Kurdistan Region. The increasing dependency of Kurdish media—particularly digital platforms—on political figures has led to a precarious situation where journalists, under political pressure, may be compelled to publish misleading or fabricated content that contravenes ethical and legal standards. This dynamic has, at times, exacerbated social instability, intensified political tensions, and violated religious, national, and human rights values. Ultimately, the state of press freedom and freedom of expression in the Kurdistan Region is contingent upon the political leadership’s openness to criticism and critical discourse. Greater political transparency and tolerance for journalistic scrutiny are essential for fostering a more independent and ethical media landscape.
The leadership of the social ministries of the Russian government: features of recruitment sources and career trajectories
Authors: Tev Denis
Published: February 2025

The recruitment channels and careers of high-ranking officials of the social ministries of the Russian government are analyzed. The study is based on a biographical database of 104 deputy ministers and department directors from six ministries. The study showed that bureaucratic professionalization is the most pronounced characteristic of officials’ careers. The main channel for their recruitment is the federal administration, and the vast majority have already worked in their ministry for some time before taking on their current position. These trends may indicate the importance of meritocratic selection based on competence. However, officials with a career spent primarily in the federal administration, especially in one ministry, are in the minority. There is interdepartmental mobility, with a number of officials came from the financial ministries, which can increase the influence of these bodies on the social bloc, contributing to the formation of its policies in a neoliberal spirit. After the administrative sphere, the most significant supplier of officials are social organizations subordinate to ministries (institutions of science, education, health care, social security, culture and sports). At the same time, business occupies a relatively modest place as a channel for recruiting officials from social ministries (especially in comparison with economic ministries). In general work experience in business, as well as regional administrations and social organizations, is found more often, and intradepartmental recruitment is less common among deputy ministers. In addition, there are ministries with particularly pronounced intradepartmental recruitment and ministries with relatively developed recruitment from business. Finally, in some ministries there is overlap between ministers and their subordinates in previous careers, which may indicate a patrimonial nature of selection.
Representative authority in Russian municipalities: composition of the deputy corpus
Authors: Vitkovskaya Tatyana
Published: February 2025

The article is about the composition and structure of the deputy corps of representative bodies of local self-government in modern Russia. The informal internal structure of the deputy collective is shown — the division of the deputy corps into segments: employees of municipal budgetary institutions, employees of municipal unitary enterprises, representatives of small private business, representatives of large business. The circumstances that constitute the context of the election and deputy activities of representatives of different segments are explained. The causes and consequences of the independence / dependence of the segments of assemblies on the executive power are revealed. The article is written based on the materials of an empirical study of power in five Russian municipalities, and a database containing information on the professional and corporate composition of representative bodies of local self-government of these municipalities (Berezovsky, Verkhny Tagil, Gubakha, Kushva, Chusovoy). The author sees the study of the composition of local assemblies and its effects on local politics as a relevant scientific task, and the study of the sectors of the municipal deputy corps as a step towards its solution.
Crisis and stability in the mirror of the regional elite’s opinions (cases in-depth interviews)
Authors: Shentyakova Anna
Published: February 2025

The article examines the opinions of the regional elite on the crisis and sustainability in modern Russia. Economic and political sustainability are important conditions for the state stability. Crisis factors violate the usual institutional orders and become a challenge for the ruling elite. The empirical basis of the study is the in-depth interviews with representatives of the regional / local political, administrative and economic elite. The sample included 8 regions of the North-West Federal District of the Russian Federation. The criteria of the positional approach were used to determine the status of the respondent. A qualitative analysis of the texts revealed differences in the perception of the crisis among representatives of two sub-elite groups. Age as a criterion also revealed differences in assessments / opinions and allowed us to divide all participants into two groups of «optimists» and «skeptics». The respondents — business representatives — evaluate the consequences of the crisis painfully and the elements of sustainability very critically. In the minds of people from regional and local administrations, the crisis phenomena of the last 5 years is not assessed as a serious threat that the system will not be able to cope with without significant losses. Sustainability indicators do not cause concern.

From latent constructs to networks: modeling high-dimensional social inferences in naturalistic settings
Authors: Lin Chujun , Lu Junsong
Published: February 2025

Long-standing research suggests that social inferences are captured by a few latent dimensions (e.g., warmth and competence). Others argue that social inferences are more complex but lack empirical support. Here, we conducted two pre-registered studies to test the high-dimensional properties of social inferences. To maximize generalizability, we computationally sampled diverse naturalistic videos and recruited U.S. representative participants (N = 1,598). Participants freely described people in videos using their own words. Cross-validation identified 25 latent dimensions which explained only 15% of the variance in the data. Alternatively, a sparse network model representing the unique correlations between inferences better represented the data. The network models informed the dynamics of naturalistic inferences, revealing how different inferences co-occurred and how they unfolded over time from concrete to abstract (Study 1). The network models also indicated cultural differences in how one inference was related to another between samples (Study 2, Asian N = 651, European N = 792). Together, these findings show that the high-dimensional network approach provides an alternative model for understanding the mental representation of social inferences in naturalistic contexts, which provides new insights into the dynamics and diversities of social inferences beyond the static, universal structure found with traditional low-dimensional latent-construct approaches.
Biased AI Writing Assistants Shift Users’ Attitudes on Societal Issues

Published: February 2025

AI writing assistants powered by Large Language Models (LLMs) are increasingly used to make autocomplete suggestions to people as they write. Can these AI writing assistants impact people’s attitudes in this process? In two large-scale preregistered experiments (N=2,582), we exposed participants writing about important societal issues to an AI writing assistant that provided biased autocomplete suggestions. When using the AI assistant, the attitudes participants expressed in a post-task survey converged towards the AI’s position. Yet, a majority of participants were unaware of the AI suggestions’ bias and their influence. Further, the influence of the AI writing assistant was stronger than the influence of its suggestions when presented as static text, showing that the influence is partially due to AI writing assistants leading people to incorporate biased viewpoints into their own writing. Lastly, warning participants about assistants’ bias before or after exposure does not mitigate the influence effect.
Cognitive Control Difficulties Differentiate Callous-Unemotional Traits from Conduct Problems: A Pre-registered Double-blind Randomized Controlled Trial Analysis
Authors: Winters Drew E. , Spitz Juliet , Raymond Kristen , Natvig Crystal , Waller Rebecca , Mikulich Susan , Schacht Joseph , Sakai Joseph T.
Published: February 2025

Background: Cognitions role in youth antisocial phenotypes of callous-unemotional (CU) traits (i.e., lack of remorse, guilt, and empathy) from conduct problems (CP; i.e., antisocial patterns of disruptive and aggressive behaviors) has been a debated topic. Recent evidence points to the need for more nuance in parsing different inhibitory processes. Specifically, selective control (i.e., selectively inhibiting a prepotent response for an alternative to specific stimuli) rather than passive control (i.e., non-response action restraint) has been linked, independent of CP, to affective processing deficits in CU traits. However, it is not known whether CU traits relate to a general difficulty with cognitive demands or a specific impairment in selective control. Methods: The present study tested whether CU traits were differentially related to difficulties in passive versus selective control, while accounting for CP. The design for this test leveraged a randomized parallel-arm design with test and control groups. Data from 85 participants aged 12-14 (female 47%) were analyzed using mixed effects analysis accounting for individual variance across repeated measures.Results: CU traits were associated with better passive control performance but worse selective control performance, whereas CP were unrelated to these trials when including CU traits. These findings were supported across individual trial type accuracy and reaction time, as well as contrasts between trials (e.g., selective > passive). Follow-up analysis suggested that CU traits were related to a more rigid cognitive style during selective control trials only. Conclusions: This study provides additional evidence of a specific cognitive limitation in selective control that differentiates CU traits from CP. Additionally, initial evidence on cognitive strategy during selective control may implicate difficulties with cognitive resources in how cognitive information is processed that aligns with work on adult psychopathy. Thus, selective control may be an important feature for understanding antisocial etiological pathways.

Big Team Science involves multiple sites of independent research labs from potentially all over the world coming together to run the same study. The power with which these studies tackle issues of replicability and generalizability are unprecedented in Psychological science. Here, we discuss new places Big Team Science can go on top of investigating issues of replicability and generalizability. 1) Big Team Science can leverage collective intelligence to identify studies that are foundational to specific theories and test them; 2) Big Team Science can leverage the data collection capabilities of numerous labs to collect data on hard to reach populations to provide theoretical advances in psychology; 3) Big Team Science can be merged with adversarial collaborations to put theories in psychology to strict experimental tests. With the growth of Big Team Science comes new avenues for advancing psychological theory.

Does a bilingual’s language environment, whether L1- or L2-dominant, modulate their use of language control mechanisms in speech production? The language-switching task (LST) typically assesses two indices of language control: asymmetric switch costs, where switching into L1 incurs greater costs than switching into L2, and reversed language dominance, where L1 becomes slower than L2. We ask if these measures are affected by the language context a bilingual is in and whether the relative balance between languages is sustained after mixed language use. Polish-English unbalanced bilinguals performed the LST in L1- and L2-dominant contexts. We found that language context modulated the magnitude of language control indices. In the L1-dominant context, we replicated effects typical for unbalanced bilinguals: asymmetric switch costs and reversed language dominance. However, in the L2-dominant context, the asymmetry of switch costs was reversed, and the reversed dominance effect decreased. Furthermore, to measure if language dominance reversed from their usual dominance and whether the language context modulations were sustained after leaving, participants named pictures in pure language blocks before (pre-LST) and after (post-LST) LST. Initially, unbalanced bilinguals exhibited a typical L1 dominance (i.e., faster L1 than L2 naming) which reversed during LST and remained reversed post-LST. The modulations of bilingual language control suggest that immediate language context flexibly shapes control mechanisms for effective production, with adjustments persisting beyond the L1- or L2-dominant context. Thus, mechanisms of control are highly adaptive to contextual demands rather than being solely determined by the language proficiency or other fixed speaker traits.

The occurrence of thermoacoustic instability in the non-equilibrium two-phase flow of the coolant can significantly affect the reliability and integrity of the nuclear reactor's internal devices. At present, the development of adequate and justified methods for modeling thermoacoustic instability in the active zone of a nuclear reactor is an urgent issue. The purpose of the study is to develop a criterion method for determining the conditions for the occurrence of TAN in the active zone of nuclear reactors, which will increase operational safety and provide an opportunity to develop an operational system for diagnosing the conditions of TAN in the active zone of high-power reactor installations. For the conditions of transient and emergency modes of nuclear power plants with VVER, the thermodynamic approach of determining the conditions for the occurrence of thermoacoustic instability of a non-equilibrium two-phase coolant is more justified. Based on the thermodynamic approach, the conditions of thermoacoustic instability of the coolant in the active zone of the reactor were obtained. They depend on the defining thermodynamic parameters – reactor power, coolant consumption, pressure and temperature of the coolant at the entrance and exit of the active zone. It was established that in the nominal operating mode of the reactor, the coolant is stable with respect to thermoacoustic fluctuations. Based on the analysis of the well-known resonance approach to modeling the conditions for the occurrence of thermoacoustic instability (on the example of a single condensing bubble), it was established that the resonance effects of the coincidence of the frequency of propagation of acoustic waves and the frequency of condensation of steam bubbles can be significant for relatively short channels (less than 1 m) at relatively low pressures. For the conditions of transient and emergency modes of nuclear power plants with VVER, the thermodynamic approach of determining the conditions for the occurrence of thermoacoustic instability of a non-equilibrium two-phase coolant, based on the regularities of the conditions for the occurrence of oscillatory processes during acoustic perturbations of the thermodynamic parameters of the coolant flow in the active zone of a nuclear reactor, is more justified.

A brief review of modern technologies for the production and use of coal-water fuel (CWF) is carried out. The trend of creating innovative technologies for the production of coal-water suspensions using hydrodynamic cavitation methods was noted. Varieties of rotary-type cavitation reactors, which are used for wet grinding of coal and the creation of finely dispersed CWF, were considered, and the advantages and disadvantages of such devices were noted. On the basis of the conducted analysis, a new type of cavitation reactor for the production of CWF, created with the participation of the authors, is proposed. It is a double-membrane hydrodynamic pulsation disperser, equipped with a Venturi nozzle, which allows achieving the high level of cavitation effects in the treatment of coal-water suspensions. The method of conducting laboratory studies on the production of CWF on the basis of the hydrodynamic pulsation apparatus and the applied measuring devices are considered. The article presents the results of an experimental study of the obtained water-coal suspensions properties, which depend on the mass concentration and processing time. The influence of these parameters on the quality characteristics of the product, such as the size distribution of coal dispersions, dynamic viscosity, stability, and also on the pH value, was determined. The CWF rheological and stable properties have been found to depend on the concentration of the suspension and the processing duration. The results of the research can be used for the practical implementation of technologies for the production of hydrocarbon fuels for further use in thermal power plants.
