Relationship between 24-h Ambulatory Blood Pressure Variability and Degree of Renal Artery Stenosis in Hospitalized Patients with Hypertension
Authors: Luo Xiaoyang , Liu Wei , Peng Xi , Li Pengqiang
Published: November 2024

Background: Blood pressure variability (BPV) is a critical risk factor for cardiovascular outcomes and is associated with atherosclerotic renal artery stenosis (ARAS), which is diagnosed using digital subtraction angiography (DSA). However, the relationship between the degree of renal artery stenosis (d-RAS), diagnosed using renal artery contrast-enhanced ultrasound (CEUS), and 24-hour ambulatory BPV in hospitalized patients with ARAS remains unclear. Methods: Hospitalized hypertensive patients were divided into ARAS and non-ARAS groups based RAS diagnoses using CEUS. The ARAS patients were further classified into unilateral and bilateral categories. Quantification of BPV over 24 hours, daytime, and nighttime utilized standard deviation (SD), coefficient of variation (CV), and average real variability (ARV). Percentage stenosis was used to evaluate d-RAS. Pearson’s and multivariate beta regression analyses were used to assess correlations between BPV and d-RAS. Results: We found that 24-hour systolic BPV (SBPV), presented as SD, CV, and ARV indices, was positively correlated with unilateral d-RAS (R1 = 0.460, p = 0.001; R1 = 0.509, p < 0.001; R1 = 0.677, p < 0.001, respectively). This correlation was consistent with the daytime SBPV (R1 = 0.512, p < 0.001; R1 = 0.539, p < 0.001; R1 = 0.678, p < 0.001, respectively) and daytime diastolic BPV (DBPV) (R1 = 0.379, p = 0.010; R1 = 0.397, p = 0.007; R1 = 0.319, p = 0.033, respectively). Similarly, 24-hour DBPV assessed by SD and CV also correlated positively with unilateral d-RAS (R1 = 0.347, p = 0.019; R1 = 0.340, p = 0.022, respectively), as did nighttime SBPV assessed by ARV indices (R1 = 0.415, p = 0.005). No significant correlations were found between BPV and bilateral d-RAS (p > 0.05). Multivariate beta regression analysis indicated that 24-hour SBPV (odds ratio [OR] = 1.035, 95% confidence interval [CI]: 1.054–1.607, p = 0.035) and daytime SBPV (OR = 1.033, 95% CI: 1.004–1.061, p = 0.023; both evaluated via AVR) were independent risk factors for d-RAS. Conclusions: SBPV is positively correlated with unilateral d-RAS at all time points. Both 24-hour and daytime SBPV (evaluated using ARV indices) were identified as independent d-RAS risk factors.

Published: November 2024

Background: Peripartum cardiomyopathy (PPCM) is a rare disease that causes maternal morbidity and mortality worldwide. However, the etiology of PPCM is still unclear, and the rate of recovery varies between patients. Understanding the genetic factors underpinning PPCM may provide new insights into its pathogenesis. Methods: This genetic study screened six patients with severe PPCM and their family members using a panel of 204 genes associated with inherited cardiomyopathy. Results: The six probands progressed to severe cardiac dysfunction during follow-up, with a low left ventricular ejection fraction of <30% and a significant increase in left ventricular end-diastolic diameter. Genetic analysis showed that four of the six probands had pathogenic mutations. No specific mutation was identified in the other two probands. Further screening of the probands’ families identified that eight family members shared the same mutation with their probands. The total positive genetic mutation rate was 46% (12/26). Among those with genetic mutations, women who had pregnancies showed symptoms of heart disease. Conclusions: For PPCM patients with a genetic predisposition, pregnancy may exert pathogenic effects in terms of disease initiation and progression. Patients with PPCM with a first-degree relative diagnosed with inherited cardiomyopathy may benefit from genetic counselling.
Diagnosis and Management of Ventricular Septal Defects
Authors: Rao P. Syamasundar
Published: November 2024

This review addresses the diagnosis and management of ventricular septal defects (VSDs). The VSDs are classified on the basis of their size, their number, and their location in the ventricular septum. Natural history of VSDs includes spontaneous closure, development of pulmonary hypertension, onset of infundibular obstruction, and progression to aortic insufficiency. While initial diagnostic approaches such as careful history-taking, physical examination, chest X-rays, and electrocardiograms provide basic information, echo-Doppler studies are essential for assessing the defect's clinical significance and determining the need for intervention. Intervention is usually indicated for symptomatic patients with moderate- to large-sized VSDs. Surgical closure is advised for perimembranous, supracristal and inlet VSDs, and for deficits involving prolapsed aortic valve leaflets. While percutaneous methods to occlude perimembranous VSDs with Amplatzer Membranous VSD Occluder are feasible, they are not recommended due to a notable risk of inducing complete heart block in a significant number of patients. Alternatively, percutaneous and hybrid methods employing the Amplatzer Muscular VSD Occluder are effective for treating large muscular VSDs. The majority of treatment options have demonstrated satisfactory outcomes. However, practitioners are urged to exercise caution in managing small defects to avoid unnecessary procedures and to ensure timely intervention for large VSDs to prevent pulmonary vascular obstructive disease.

Published: November 2024

Current guidelines recommend closing a patent foramen ovale (PFO) in patients who have experienced a cryptogenic or cardioembolic stroke, have a high-risk PFO, and are aged between 16 and 60 years (class A recommendation, level I evidence). In terms of efficacy, in the CLOSE and RESPECT trials, the number needed-to-treat (NNT) to prevent one stroke recurrence in a five-year term was between 20 and 44. Other trials, such as the REDUCE trial, presented much better data with a NNT of 28 at two years and as low as 18 over a follow-up period of 10 years. Interventional PFO closure is relatively straightforward to learn compared to other cardiology procedures; however, it must be performed meticulously to minimize the risk of post-procedural complications. Usually, a double-disk occlusion device is used, followed by antiplatelet therapy. While the potential benefits of PFO closure for conditions such as migraines are currently being studied, robust trials are still required. Therefore, deciding to close a PFO for reasons other than stroke should be considered on a case-by-case basis.
Glucose Metabolism Reprogramming of Vascular Endothelial Cells and Its Implication in Development of Atherosclerosis
Authors: Luo Shiwen , Li Liu , Chen Huiqing , Wei Jingyue , Yang Dongmei
Published: November 2024

Atherosclerosis (AS) is an important cause of morbidity and mortality in cardiovascular diseases such as coronary atherosclerotic heart disease and stroke. As the primary natural barrier between blood and the vessel wall, damage to vascular endothelial cells (VECs) is one of the initiating factors for the development of AS. VECs primarily use aerobic glycolysis for energy supply, but several diseases can cause altered glucose metabolism in VECs. Glucose metabolism reprogramming of VECs is the core event of AS, which is closely related to the development of AS. In this review, we review how glucose metabolism reprogramming of VECs promotes the development of AS by inducing VEC barrier dysfunction, autophagy, altering the inflammatory response, and proliferation of VECs, in the hopes of providing new ideas and discovering new targets for the prevention and treatment of AS.
‘Of course we make money, but it has to be in a responsible way’: Safer gambling practices of state-owned gambling operators
Authors: Newall Philip , Whybrow Allegra Katharine , Torrance Jamie
Published: November 2024

Objective: Gambling can be regulated in different ways, with some jurisdictions having competitive markets of privately-owned operators, some jurisdictions having state-owned operators that have exclusive legal monopolies, and in other jurisdictions former state-owned monopolies now compete in markets against privately-owned operators. While privately-owned operators tend to emphasize gamblers’ individual responsibility while implementing suboptimal voluntary harm-prevention measures, less is known about the safer gambling practices of state-owned gambling operators, a topic which we aim to contribute to here.Method: Semi-structured interviews were conducted with participants employed in safer gambling roles at state-owned gambling operators in 10 jurisdictions, with transcripts then thematically analyzed.Results: Participants highlighted key advantages of the state-owned model, such as building trust and leading on harm-prevention initiatives in competitive markets, and by generating profits ‘in a responsible way’. Specific safer gambling practices included the prominent placement of tools for gamblers to use, operator-driven limits and interactions, and a recognition of the need to strike the right marketing balance. Of former state-owned monopolies that now acted in competitive markets, it was noted that this change in market structure did not necessarily eliminate illegal gambling, that this change could lead to a proliferation of marketing from privately-owned operators, and that the consequent spreading of gambler activity across multiple operators posed additional challenges regarding safer gambling.Conclusions: State-owned gambling operators appear unique in terms of their incentive and capability to prevent gambling harms. Their insights should be integrated into new harm-prevention approaches for today’s online and interconnected gambling world.

Published: November 2024

The purpose of this study is to assess the relationship between emotional forgiveness (presence of positive emotions towards the offender and reduction of negative emotions towards the offender) and personality traits (agreeableness, neuroticism, conscientiousness, openness to experience and extraversion) in the perspective of a longitudinal study among juveniles referred by family courts to a probation center or youth educational center. This investigation included 553 juveniles between the ages of 11 and 18. Our findings indicate that agreeableness (T1) is the predictor significantly associated with emotional forgiveness (presence of positive emotions towards the offender, T2). In contrast, neuroticism (T1) was negatively associated with a reduction in negative emotions towards the perpetrator (T2). Agreeableness and neuroticism have an important role in developing forgiveness, which has practical implications in the area of intervention and parenting for juveniles referred by the courts to educational institutions. As a result, juveniles struggling with problems related to their lack of forgiveness skills and abilities may suppress anger and negative emotions. Therefore, such individuals should be systematically motivated to express their emotions in order to learn the skills to regulate and control them, but also to pay attention and take the point of view of others.
Children’s Belief in Santa Claus and Moral Behavior: A two-wave longitudinal study of children’s prosocial behavior during Christmas.
Authors: Kapitány Rohan , Francis Kathryn , Wilks Matti , Kavanagh Christopher Michael , Whitehouse Harvey
Published: November 2024

Children are told that Santa Claus is a real agent who can observe them, judge them, and reward them. Famously, Santa makes a list (and checks it twice) of children who are ‘naughty’ and ‘nice’. Our goal was to determine which factors, if any, influence whether belief in Santa or other traditions associated with the Christmas Festival, would influence a child’s moral development. Over three studies executed in 2019, 2021, and 2022, and including over 400 participants, we asked parents to report on their child’s (4 to 9 years) behavior at two timepoints: up-to six weeks prior to Christmas and for the week preceding Christmas Day. We constructed and refined a tool for parental report of everyday behaviors of children that broadly covers positive/prosocial behavior and negative/antisocial behaviors. We find that a child’s belief alone is insufficient to predict positive behaviors, but that the presence and intensity of ritual behaviors associated with Christmas (such as Christmas Trees and other decorations, songs and other forms of media, and different kinds of foods and other patterns of behavior) influence positive behavior, and specifically influence unprompted behaviors in the children. Further, a parent’s aspiration to model Christmas relevant behaviors (measured by a modified CREDs scale) indirectly affects the child’s behavior. Other potential predictors of behavioral improvements were ruled out, including parents’ mood, whether parents’ explicitly reminded their children of Santa, the amount of free-time and family-time a child has during the Christmas period, and various aspects of religiosity (though our sample was highly secular). We report, for the first time, that a child’s behavior actually improves as Christmas Day approaches, and though the effect is small it is reliably observed, and is primarily attributable to participation in yuletide rituals. These results have practical and theoretical implications for the evolution of moralizing religions in our species.

AbstractObjective: Physicians at the University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla, Enugu, demonstrate a passion for multidisciplinary healthcare and effective communication. However, there is limited understanding of the roles and contributions of dietitians within the healthcare team. Methods: The study adopted a cross-sectional survey design. Multi-stage sampling technique was used in selection of respondents. The study involved 228 physicians’ from different departments in the hospital. A well-structured and pretested questionnaire was used for the study in assessment of the respondents. The questionnaire was validated by four lecturers in Department of Nutrition and Dietetics, University of Nigeria, Nsukka. Data was analyzed using Microsoft excel and Statistical Package for service solution (SPSS V.22) with an acceptable prevalence (P-value) of < 0.05. Results: The male respondents were 50% while the female respondents were 50% as well. Most of the respondents had an age range of ≤ 25 years. More than half (51.8%) of the respondents had work experience of ≤ 5 years while 22.4% have worked for ≥ 11 year. Among the resident physicians, 59.65% had excellent knowledge of roles and services rendered by dietitians in the hospital. Most (79%) of the physicians had poor perception of the skills used by dietitians in nutrition counseling and the methods used in carrying out dietetics services (NCP) in the hospital. Discussion: In respect to the results of this study, it is relevant to broaden the knowledge of physicians’ and other health workers on the essence of dietetics services and adequate dietetics practice in the hospital.
Evidence for large disturbances of the Ediacaran geomagnetic field from West Africa
Authors: Robert Boris , Corfu Fernando , Domeier Mathew , Blein Olivier
Published: November 2024

Constraining the paleogeography of the Ediacaran is crucial for understanding the extensive tectonic, biological and geochemical changes that occurred during that epoch. Paleomagnetism is an essential tool for reconstructing the Ediacaran paleogeography but it is complicated because the paleomagnetic data of that age display unusually fast and large directional oscillations. Two main competing hypotheses have been proposed: the occurrence of very fast True Polar Wander (TPW) episodes, which correspond to the motion of the planetary spin axis relative to the solid Earth, or strong geomagnetic field disturbances that could potentially be dominated by an equatorial dipole field. Their implications for paleogeographic reconstructions are radically different as TPW would result in a major latitudinal shift of continents of up to ∼ 90°. In this study, we focus on one rapid paleomagnetic change recorded in pyroclastic rocks of the Ouarzazate Group in the Anti-Atlas Belt (Morocco) that has been interpreted to reflect an exceptionally fast episode of True Polar Wander between ∼ 575 and 565 Ma. To further test this hypothesis, tight constraints on the rate of the paleomagnetic directional change are needed, as TPW is speed-limited by mantle viscosity. Here, we present high-resolution Chemical Abrasion Isotope-Dilution Thermal Ionization Mass Spectrometry (CA-ID-TIMS) U-Pb dates on zircons from seven pyroclastic levels distributed stratigraphically below, in between and above the horizons where the large paleomagnetic change is observed. Based on these new data, we estimate the associated lower bound rate of the apparent polar motion related to this abrupt paleomagnetic change to be 11.6°/Myrs [5.5 – 17.9]. This value is much higher than the TPW speed limit estimated from numerical simulations, suggesting that this large paleomagnetic change cannot be explained by TPW. It could rather be associated with intense perturbations of the Ediacaran geomagnetic field potentially oscillating from an axial to an equatorial dipole. The paleomagnetic pole that we interpret as referring to the axial dipole field would imply that West Africa was located at high latitude during the mid-Ediacaran.

Published: November 2024

We compared the effect of test format – either paper-and-pencil (postal) or online inpeople’s homes – on three common tests of cognitive ability: 1) the Cattell test of fluidintelligence, 2) the Spot-The-Word test of vocabulary knowledge and 3) the LogicalMemory test of immediate and delayed memory for a short story. The effect of format wasassessed in two ways: 1) in a small sample of volunteers across the adult age range whoperformed one-half of the trials in each format, and 2) in a large sample from the CamCANcohort (www.cam-can.org), approximately half of whom experienced either one format orthe other. We found that the Cattell and Spot-The-Word tests showed good agreementacross formats (e.g. using the ICC metric) and no evidence of an interaction with age.However, the Logical Memory test showed poor agreement and interacted with age.

Published: November 2024

Large Language Models (LLMs) have emerged as powerful tools with potential applications across multiple sectors, including healthcare, where resource constraints make efficiency gains particularly valuable. However, the domain of mental healthcare presents distinct challenges, as its vulnerable patient population necessitates high standards of clinical performance and safety. To address this, we introduce the Limbic Layer — a novel system of machine learning (ML) models designed to augment LLMs with specialized clinical decision-making capabilities specific to a mental health setting. This study evaluated the impact of the the Limbic Layer on clinical performance and safety compared to a state-of-the-art, stand-alone LLM (OpenAI GPT-4). We investigated the impact from the perspective of service users as well as trained clinicians. In the first phase, users interacted with either a prompted LLM or an LLM powered by the Limbic Layer. We found that the Limbic Layer demonstrated superior performance in both therapeutic relationship building and clinical skills. In the second phase, clinicians blindly assessed the user conversations, rating the Limbic Layer as significantly more clinically accurate than the stand-alone LLM. This enhanced clinical accuracy was reflected in clinician preference, with 94% indicating they would prefer patients to be treated by the Limbic Layer compared to a stand-alone LLM. These findings suggest that the Limbic Layer significantly improves the clinical performance and safety profile of state-of-the-art LLMs, unlocking their implementation in real-world clinical settings.
AI-generated face detection: Why super-recognisers succeed where others fail

Published: November 2024

AI-generated faces have become virtually indistinguishable from real human faces. In this study, we demonstrate that super-recognisers—individuals with exceptional face recognition abilities—can reliably detect AI-generated faces, while typical observers cannot. Super-recognisers (N=36) and typical observers (N=89) were shown images of real and AI-generated faces and classified each as real or fake. Super-recognisers performed significantly above chance, with decision confidence positively correlated with accuracy, indicating metacognitive insight. In contrast, typical observers performed at chance level, with no insight into their accuracy. Aggregating responses using a wisdom-of-crowds approach improved super-recogniser accuracy substantially but did not affect typical observer accuracy. To understand the basis of super-recognisers’ enhanced sensitivity to real faces, we examined the facial cues used by each group. Super-recognisers and typical observers showed qualitative differences, with super-recognisers relying less on perceived familiarity and memorability—cues that have previously misled typical observers when assessing face authenticity. These findings suggest that understanding individual differences in face-processing ability may help mitigate risks associated with hyper-realistic AI faces.

Do team members' physiological signals synchronize during collaboration, and can this alignment predict how well the team adapts and performs? In a laboratory study involving 47 four-person teams engaged in a collaborative game, we used synchrony and regularity in heart rate and skin conductance to reflect team physiological coordination and examined how this coordination relates to team adaptation and overall performance. We found that regularity in heart rate and skin conductance decreased across levels of game play, while synchrony in skin conductance increased, particularly when teams had to adapt to task changes. Moreover, higher levels of regularity in heart rates and lower levels of regularity in skin conductance predicted performance through associations with team adaptation. In addition, synchrony in skin conductance also predicted team performance. These results show promising potential for using wearable technology to measure real-time team adaptation processes and predicting team performance in crisis situations.

Published: November 2024

The growing integration of AI tools in communication promises enhanced efficiency and productivity. However, concerns about the erosion of trust and authenticity have fueled debates over the disclosure and regulation ofAI-mediated communication. It remains unclear a) how AI mediation influences trust, b) whether the efficiency gains outweigh potential compromises in trust, and c) how proposed transparency policies would impact these trade-offs. To address these questions, we conducted two online studies (total N = 1637). We adapted the well-established incentivized trust game to measure objective behavioral trust. Additionally, we use subjective, self-reported trust ratings. Before each game, some participants could write a message with or without an AI assistant to elicit trust. We also systematically varied actual and expecteddisclosure of AI assistance. Results reveal that AI assistance had little to no consequences for trust, even when AI use was transparent. However, participants using AI assistance composed their messages more quickly, achieving higher returns of trust per writing time invested. Importantly, this efficiency boost was not suppressed by expected or actual disclosure of AI involvement. Contrary to prevailing concerns, these results suggest that AI-mediated communication could enhance efficiency and facilitate trust-building rather than undermine it.

Investment and Profitability of Commercial Banks in Nepal
Authors: Kharel Taranath
Published: November 2024

The objective of this study is to analyze the impact of investment on profitability of selected Nepalese commercial banks. This research employs a descriptive and causal comparative research design. Given the impracticality of including all banks, the study focuses on a selected sample of twenty banks, specifically NABIL bank limited and Standard Chartered bank limited, chosen through judgment sampling. Secondary data, including annual reports and various published sources has used for analysis. The research employs statistical tools such as arithmetic mean, standard deviation, coefficient of variation, correlation coefficient, and regression analysis to evaluate and interpret the data. The results indicate that higher NRB Balance and Investment on Security are positively associated with both return on assets (ROA) and return on equity (ROE), suggesting that banks with larger reserves and substantial investments in securities tend to achieve better profitability. Conversely, Loan and Advance to Customers show a strong positive correlation with ROA but a negative correlation with ROE, indicating that while increased lending boosts asset returns, it may reduce returns on equity and investment in securities. Regression analyses further illuminate these relationships. For ROA, Bank Size emerges as the most significant factor, with a strong positive impact, followed by NRB Balance and Loan and Advance to Customers, which also positively influence ROA. Investment on Security, although positively related, has a less pronounced effect.

Erol Güngör’ün İslam Tasavvufu Üzerine Görüşleri
Authors: Yıldız İlhan
Published: November 2024

Erol Güngör, kitap, makale ve yazılarında İslam tasavvufunun karmaşık ve tartışmalı doğasını derinlemesine ele alır. Güngör, tasavvufun İslam mistisizmi olarak kabul edilmesi gerektiğini belirtirken, bu alanın subjektif ve ezoterik yapısının suistimale açık olduğunu vurgular. Tasavvufun bireysel manevi deneyimlere ve içsel keşiflere büyük önem verdiğini belirten Güngör, bu yönün farklı yorumlara ve uygulamalara yol açtığını söyler. Ayrıca, tasavvufun Asrı Saadette izlerine rastlanmadığını ve İslamiyetten sonra ortaya çıktığını savunur. Güngör, tasavvufun bilimle olan uyumunu bozduğunu ve hurafelere dayandığını iddia eder. Bazı eleştirmenlerin tasavvufu İsrailiyatla ilişkilendirerek İslam'ı yıkma aracı olarak gördüğünü belirtir. Bununla birlikte, tasavvufu savunan Rene Guenon gibi düşünürlerin görüşlerine de yer verir. Guenon, tasavvufun İslam'ın mistik yönünü temsil ettiğini ve müsteşriklerin bu iki kavramı karıştırdığını savunur. Reynold A. Nicholson ve benzeri Batılı akademisyenlerin tasavvufun kökenlerine dair teorilerine de değinen Güngör, tasavvufun Yeni Eflatunculuk, Hint ve İran mistisizmi gibi dış kaynaklardan etkilenmiş olabileceğini öne sürer. Bu etkileşimler, tasavvufun bazı öğretilerinin ve pratiklerinin kökenlerini açıklayabilir. Güngör, tasavvufu ikiye ayırır: Gazali, İbni Arabi ve Mevlana’nın temsil ettiği medrese-dergah düzleminde çalışan kent tasavvufu ve Hacı Bektaş Veli gibi tasavvufçuların savunduğu, medreseyi küçümseyen ve dergah merkezli köy tasavvufu. Günümüzde tasavvufun ehil ellerde olmadığını ve Müslümanlar, özellikle gençler için tehlike arz ettiğini belirtir. Güngör'ün tasavvufa dair kapsamlı analizi, tasavvufun İslam düşüncesindeki yerini anlamak için önemli bir kaynaktır.

Purpose: to develop a method for justification of the priority and order of repair and restoration work on land reclamation systems based on the technical condition assessment of the objects of land reclamation systems, as well as their significance for the system operation as a whole using the example of the Bg-R-8-1 channel of the Bagaevskaya irrigation system.
Materials and methods: materials on the Bg-R-8-1 channel of the Bagaevskaya irrigation system were used as initial data for developing the proposed method.
Results. When substantiating the priority and order of maintenance work on waterworks of land reclamation systems, it is necessary to assess the technical condition of each structure, as well as its performance significance for the land reclamation system operation as a whole. The technical condition of the elements of land reclamation systems is determined on the basis of field studies and approved by a technical inspection report. Then each element is assigned a corresponding technical index: standard, operational, partially operational or limit state. To assess the significance, it is necessary to determine the number of elements of the reclamation system, the efficiency of which depends on the reliable operation of the structure under consideration, as well as the actual, design and command irrigation area, the irrigation of which is affected by the reliability of the element under consideration. The priority indicator is defined as the product of the operational significance index and technical condition index. The priority of maintenance work is determined by ordering the resulting values from the largest value to the smallest.
Conclusions. The proposed approach will improve the efficiency of using financial resources and ensure more rational planning of maintenance work on the reclamation systems.

Purpose: substantiate the design and technological parameters of hydrocyclones-clarifiers by means of a detailed study of the radial velocity in significant sections, namely, at the transition from the cylindrical to the conical part of the apparatus, in the technology of water purification for irrigation.
Materials and methods. Modeling and study of the complex process of changing the radial velocity was carried out in two stages. At the first stage, an experiment was carried out on a 170 mm diameter hydrocyclone-clarifier using a numerical method based on the ParaView and OpenFOAM software package, the limit of radial velocity change was established at a given velocity at the inlet to the apparatus, and a database in the form of a matrix was obtained. At the second stage, the obtained array of experimental data describing the velocity change, reflecting the physics of the processes taking place, was subjected to digital analysis to obtain dependencies and extrema of the function.
Results. During the experiment and digital analysis it was determined that the extreme minimum value of the radial velocity is observed at the apparatus wall at the point minus 76 at the velocity equal to 13.06 m/s at the hydrocyclone inlet. Under certain conditions, the radial velocity has a zero value; for example, for an apparatus with a diameter of 170 mm in a cross-section of minus 50 mm at the transition from the cylindrical to the conical part, this phenomenon was established at the velocity equal to 18.75 m/s at the hydrocyclone inlet.
Conclusions. The data on the change in the radial velocity in the hydrocyclone-clarifier depending on the velocity at the apparatus inlet at each point to the left and to the right of the air cord are summarized. These studies will allow in the future to simulate the optimal design and technological parameters of the hydrocyclone clarifier for the specified natural conditions, which will make it possible to bring the water quality to the requirements acceptable for irrigation.

Purpose: to conduct research dedicated to assessing the impact of primary soil cultivation techniques and the microelements application on the yield of cereal and leguminous grain crops.
Materials and methods. The effect of moldboard plowing (25–27 cm), flat-cutting (20–22 cm), minimum surface tillage (8–10 cm) and no-tillage on the yield of leguminous crops (soybeans, peas, chickpeas) and cereal grains (spring wheat, Sudan grass) is studied. The studies were conducted at the experimental production farm of the Volga Research Institute of Hydraulic Engineering and Land Reclamation in 2022–2024 using generally accepted methods.
Results. The impact of basic tillage techniques and the impact of micro-fertilizers on vegetation in cereal and leguminous crops agrocenoses on productivity and its structure have been studied. The use of flat-cutting and the micronutrients application for cereals and legumes increased the yield indicators on average for soybeans – by 65.9 %, peas – 48.5 %, chickpeas – 41.8 %, spring wheat – 61.3 %, Sudan grass – 26.3 % compared with the no-tillage option. The maximum yield was obtained on soybeans with the use of flat-cutting tillage – 3.45 t/ha, and the minimum at no-tillage – 1.94 t/ha. The impact of flat-cutting tillage on the spring wheat productivity is expressed by an increase in yield by 0.34 t/ha, compared with no-tillage. Chickpea yield is higher when using flat-cutting tillage with leaf dressing – 2.75 t/ha, and without tillage and dressing – 1.87 t/ha. The yield of Sudan grass of two staves when using flat cutting tillage with the micronutrients application on vegetation is 40.37 t/ha and 31.50 t/ha with no-tillage.
Conclusions. For the soil and climatic conditions of the dry steppe Volga region, it has been proven that when cultivating chickpeas, soybeans, peas, Sudan grass and spring wheat as examples, the best indicators of the crop structure were achieved in variants using flat-cutting tillage against the background of the micronutrients application to vegetative plants.

Purpose: to determine the effect of soaking Jaguar pea seeds in a solution with biopreparations, such as “Biohumus Concentrate” and “Biohumate + 9 Microelements”, on the crop growth and development in various soils.
Materials and methods. Laboratory studies were conducted in 2024 at Federal Agricultural Kursk Research Center. Pea seeds were germinated in germination chambers of 100 pcs. for 4 and 8 days on various soils. Before germination, the seeds were pre-soaked for 24 h in tap water, in “Biohumus Concentrate” diluted with water at a dose of 10 ml of the preparation per 1 l of water, in “Biohumate + 9 Microelements” at a dose of 10 ml of the preparation per 1 l of water, then the results were compared with the control option without additional soaking.
Results. It was found that the maximum effect on plant height (5.8 cm) and root length (15.9 cm), wet (17.0 g) and dry (1.68 g) plant weight was observed when using the preparation “Biohumate + 9 Microelements” and the soil Terra Vita. Wet and dry weight of the roots of 100 plants was the highest when using the preparation “Biohumate + 9 Microelements” on all the studied soils (the increase relative to the control was 18.7–61.7 and 17.9–70.0 %, respectively). In all other experimental variants, no difference in the effectiveness of the biopreparations was found. With a decrease in soil fertility, seed germination and dry weight of roots decreased, but the amount of dry matter in pea roots increased. The wet weight of 100 roots of pea plants increased under the influence of biopreparations (r = 0.55, α = 0.05) and decreased with a decrease in soil fertility (r = –0.69, α = 0.05).
Conclusion. It was found that preliminary soaking of pea seeds of the Jaguar variety in a solution with biopreparations “Universal Biohumus Concentrate” and “Biohumate + 9 Microelements” for 1 day causes an increase in the germination energy of seeds, plant height, root length, wet and dry weight of plants and roots on all studied soils.
