The subject of this study is the technological processes of separation, the hull of industrial hemp seeds, an aspiration column, and whole kernels.
The problem solved was determining the technical and technological solutions that could enable the intensification of production processes for separating industrial hemp seeds.
The separation of hemp seed hull by linear dimensions on sieves with round and elongated holes has been investigated.
It was found that the percentage of seed hulls retained by sieves with circular holes was 25.98 % for ø3.5 mm, 23.59 % for ø3.0 mm, and 40.28 % for ø2.0 mm, respectively. Sieves ø3.5 mm and ø2.0 mm made it possible to obtain seed hulls fractions with two components conditionally different in the «mass-size» ratio.
Using sieves with elongated holes enabled obtaining fractions consisting of at least three components. Sieves with elongated working holes of 3.0×20 mm, due to their low ability (1.76 %) to retain hemp seed hull components, were ineffective.
The clogging levels of kernels in seed hulls, separated by linear dimensions on combined sieves with round and elongated holes, were as follows: separation option No. 1 – 48.70 %, option No. 2 – 45.74 %, option No. 3 – 60.25 %, option No. 4 – 49.32 %, respectively.
It was established that the use of an aspiration column made it possible to remove up to 32.1 % of clogging in the form of a light fraction. The application of the aspiration column reduced the content of seed coating in separation option No. 1 by 3.0–5.7 times, option No. 2 by 1.35–3.7 times, option No. 3 by 1.9–11.2 times, and option No. 4 by 1.5–4.8 times, respectively.
The quantitative and component composition of seed hulls fractions obtained under conditions of using an aspiration column with set rational values of the air damper opening angle α=53° and the vertical tilt angle of the air channel β=6°, was as follows: Stage I – «heavy» fraction – 51.78 %, 27.56 % – waste, up to 20 % – «light» fraction of Stages II and III

The object of the research is to identify the influence of the pitch of the hammers with cutting edges on the determination of the average length of feed, crushed from by-product stem raw materials in hammer crushers. However, a problem was identified such as the lack of an analytical expression for determining the average length of chopped stem feed by a hammer grinder depending on the distance between the edges of adjacent hammers. With a simultaneous change in the angles of the location of the stem with the maximum size in the layer and, using the methods of probability theory for determining the mathematical descriptions of the function of two arguments, in this study an analytical expression was obtained for determining the average length of particles crushed by hammer crushers depending on the distance between the faces of adjacent hammers. Hammers with cutting edges are used to crush feed from by-product stem raw materials. The end working part of the hammer is milled at an angle of 90°, i.e. two cutting edges are processed at the end of the hammer. As a result of the practical calculations, the average length of feed crushed from by-product stem raw materials was determined depending on the parameters of the hammer crusher.  From the resulting graph of the influence of the distance between the faces of adjacent hammers on the average length of crushed particles, it is evident that when the distance between the faces of adjacent hammers changes, the average length of crushed particles varies within the range of 36.19...53.39 mm. To verify the reliability of the obtained expression, experiments were carried out on a crusher with a distance between the faces of adjacent hammers of 20 mm. In this case, the average length of the crushed particles was equal to 38.75 mm, and the theoretical value was 40.16 mm. The difference between them was 3.64 %, which proves the reliability of the obtained analytical expression. The conducted theoretical studies with the receipt of an analytical expression, ensuring the determination of the average length of feed, chopped from by-product stem raw materials, is the solution to an important problem in the development of theoretical foundations of chopping machines, significantly affecting the efficiency of mechanization and operation of feed choppers in practice

Published: September 2024

Cast iron is widely used in the manufacturing industry due to its high strength and wear resistance properties. However, cast iron's brittle nature results in frequent failure of cracks during formation or use. Among the repair methods that can be used are thermal spray and the welding process. Even though both welding and thermal spray have been implemented for various metal repairs processes, however very limited technical reports as well as scientific papers are found for this topic. Therefore, the optimum condition of metal repair by both processes is still needed to be explored. The present works focus on the comparison between thermal spray and welding method for cast iron repairs purposes. In the experiment of thermal spray process focus has been given in optimizing spraying distance on microstructure and hardness properties. On the other hand, in the welding experimental works focus has been given on the influence of groove design on microstructure and hardness. Each research variable is carried out to obtain optimal crack repair results. It was observed that thermal spray process produces less Heat Affected Zone (HAZ) area compared to the welding process therefore having less critical area. The highest hardness value of thermal spray method is 101.33 shown by 30 cm spraying distance. Meanwhile, the highest hardness value of HAZ area of welding method is 600 HV shown by specimen A. It was obtained that from the present experimental works, thermal spray process produces better results than welding process. However, the value of the specimen hardness produced by the welding and thermal spray method depends on the type of coating material used

The aim of the work was to develop a «green» and extraction-free spectrophotometric procedure for the assay of rosuvastatin in tablets. The present work describes three new spectrophotometric procedures (A, B and C) that can be utilized for routine quality control of rosuvastatin in laboratories.
Materials and methods. Analytical instrumentation: Shimadzu UV-1800 double beam UV-vis spectrophotometer (Japan) with attached UV-Probe ver. 2.62 software, RAD WAG AS 200/C precise analytical balance (Poland). Rosuvastatin calcium (purity ≥98 % (HPLC)) was bought from Sigma-Aldrich Chemicals Co. (St. Louis, MO, USA). Rosuvastatin 10 mg tablets were acquired from a nearby drugstore. All solvents used in this study, including methanol, ethanol, chloroform, acetonitrile and ethyl acetate, were produced by Honeywell and had a purity of 99.9 %. BCG, BCP and BTB were acquired from Sigma-Aldrich Chemicals Co. (USA, St. Louis). All chemicals utilized in the experiment were of analytical purity.
Results and discussion. New simple «green» and extraction-free spectrophotometric procedures for assay of rosuvastatin in tablets involve the formation of ion-pair complexes with sulphophtalein dyes (BCG (Method A), BCP (Method B), BTB (Method C)) have been developed. The absorbances of the coloured reaction products were registered at 405 nm (Method A) and 400 nm (Methods B, C). The concentration was linearly proportional to absorbance values in the range of 2.51-20.08 μg/mL (method A), 2.50-24.90 μg/mL (method B) and 2.51-12.56 μg/mL (method C). Estimation of LOD and LOQ parameters were obtained as 0.67 μg/mL and 2.23 μg/mL (Method A), 0.39 μg/mL and 1.32 μg/mL (Method B), 0.30 μg/mL and 1.01 μg/mL (Method C). The stoichiometric ratio of the reactive components of rosuvastatin - BCG, BCP, and BTB corresponded 1: 1. The %RSD values of intra-day and inter-day were obtained less than < 1.5 %, which showed excellent repeatability and RE % data was ≤ 3 %. The effect on the environment of the proposed spectrophotometric procedures and their compliance with the GAC principles were endorsed by the output of AGREE, GAPI, and AES metrics tools. The values of these three «green» metrics show that the proposed spectrophotometric procedures had a low environmental impact compared with the reported ones.
Conclusions. The developed fast, simple and cost-effective methods A, B, and C can be used for routine analysis of rosuvastatin in tablets

Published: September 2024

The study attempts to analyze the implications of the war in Ukraine for the issues of development and inequalities in the BRICS block. The so-called “emerging economies” play an essential role in the global system, both in economic and political terms. The article compares the political and economic backgrounds of Brazil, Russia, India, China, and South Africa, their development, the “status quo” and their future aspirations, and analyses how the war in Ukraine may change the global development scenario. It is essential after the BRICS summit in South Africa invited six new members to the group. The article is rooted in complexity theory, supported by a mixed methodology approach. We show how the given research methodology, informed by complexity theory, can furnish new insights into global sustainability. The statistical method was used to gauge the correlation-regression impact of inequalities in BRICS countries on their sustainable development. The analysis allows several conclusions to be ventured: sustainable development is closely linked to inequalities and vice versa; the war has had a significant, multidimensional impact on the development paths and inequalities in the BRICS countries, which potentially could worsen, and the war is a major shocking event that can lead to global system changes and implications which are broader than merely for the subregion.
Interrogating School Environment as Determinant of Students’ Academic Achievement in Government as a School Subject
Authors:   Emmanuel Alayande University of Education (Nigeria), Ogunsola Abayomi
Published: September 2024

Several factors are responsible for attaining the academic success of the learners, but more importantly, the home environment, the school location, and other environmental factors surrounding the school go a long way in determining the teaching and learning outcome. The environment under which learning takes place influences, to a greater extent, the attainment of the students’ achievement. Therefore, this study interrogated the school environment as a determinant of students’ academic achievement in Government with detailed reference to the Atiba Local Government Area of Oyo State. Students studying Government as a school subject were the population of this study. Six (6) Senior Secondary Schools were drawn as samples. Twenty (20) students were selected from each school, totaling One Hundred and Twenty (120) participants. The questionnaire was adopted for data collection, while data analysis was by rank order, percentages, and mean. The study availed itself of both primary and secondary sources of data gathering and consequently discovered that the parents’ education and home environmental factors significantly impact students’ achievement in Government. It was recommended that the home and other environmental factors determine academic achievement, as this can accelerate the rate at which students learn and achieve their educational pursuits.

Charting, Rhetoric, and Technical Communication: Primary-Care Progress Notes in Rural Oregon
Authors: Birrer-Lundgren Kari J.
Published: September 2024

Medical documentation--i.e., charting--is widely known to be crucial for patient care, billing, and legal protection, but it is simultaneously largely viewed as tedious, time-consuming busywork that takes clinicians away from patients, especially in the era of electronic health records (EHRs). There has been excellent but limited research on how writing skills (and thus, explicit writing instruction) influence both the charting experience and charting outcomes (Schryer, 1993; Opel & Hart-Davidson, 2019). In this project, I investigate how progress notes within EHRs could be improved if medical providers had more training in rhetoric and technical writing. Specifically, I focus on primary care, as primary-care providers have been shown to spend the most time on EHRs (Rotenstein et al, 2023). I draw upon a corpus of de-identified primary-care progress notes and the insights of primary-care providers, both sourced from clinics in rural Oregon. My major conclusions are that primary-care providers would benefit from being taught how to write with attention to audience and purpose and that rhetoricians of health and medicine have an opportunity to help improve patient charting.

This article examines a method for assessing the impact of reservoir heterogeneity on the distribution of oil saturation in pay zones using the example of the Bajossian and Bathonian stages of the Jurassic system of the Kalamkas field. Within this field, the Jurassic oil and gas stratum under consideration lies on the eroded surface of various horizons of the Middle and Lower Triassic and is represented by uneven alternation of sand-siltstone and clay rocks, as a result of which these deposits have a complex geological structure, due in the lithological plan to uneven alternation of sand-siltstone and clay rocks. As a result, a rather complex distribution of oil (water) saturation may occur in the formation, which differs from the standard ideas about the geological structure of the object under study, i.e. the presence of such «unconventional» reservoir boundaries (oil-bearing contour) as capillary barriers of the first kind is possible. As a result of this approach, the following is obtained. For the conditions of occurrence of productive formations of the Bajossian stage of the field in question, in order to ensure that the dimensions of the capillary barrier in the reservoir do not exceed the height of 1 m at an average value of the porosity coefficient Kп = 27,6 % it is necessary to fulfill the inequality of Kпр ≥ 6,1∙10−3 μm2. For the conditions of occurrence of productive formations of the Bathonian stage, in order for the dimensions of the capillary barrier in the reservoir not to exceed the height of 1 m with an average value of the porosity coefficient Kп = 28,0 % it is necessary to Kпр ≥ 7,5∙10−3 μm2. Also, on the basis of this method, various ratios of Kпр permeability coefficients and porosity were obtained Kп at which the dimensions of the capillary barrier in the deposit will exceed the heights of 1.0, 1.5 and 2.0 m above the level of the accepted oil-water contact (OWC) for the conditions of occurrence of the Kalamkas field in question. It was noted that this approach makes it possible to assess uncertainties in the position of fluid contacts when justifying the boundaries of the oil potential contour and the distribution of oil reserves in formations with a wide range of reservoir properties.
PERIODIC FOAMING DURING SELECTIVE ISOLATION OF HIGHLY PERMEABLE CHANNELS OF POROUS MEDIUM

Published: September 2024

Selective isolation of watered interlayers by forming barriers formed by highly viscous gels or insoluble precipitates does not always lead to the desired results. Field experience confirms that at some distance from the formed barrier, the filtration flow restores its configuration and the water injected into the formation again moves through highly permeable channels. An increase in the efficiency of flow deflection can be achieved by creating not a single barrier, but a whole sequence of alternating deep-penetrating insulating barriers, separated from each other by a certain distance in highly permeable pores. The paper presents the results of studies of quasi-periodic foaming in order to control mobility under conditions of selective isolation of water in pore channels of high permeability. Foaming occurs due to the in-bulk reaction between concentrated aqueous solutions of gas-generating and gas-generating solutions. Flow pattern of injected aqueous solutions of foaming reagents along current tubes is investigated. The task is to determine the space-time distribution of reagents in given zones of the porous medium. The problem of establishing the correlation between the spatial distribution of the gas formation zone and the dynamics of the gas formation process over time on the one hand, as well as the concentration of reactants, the diffusion rate (mutual diffusion), the gas generation rate and the probability of nucleation on the other hand was solved. The degree of flow blockage in highly permeable zones of the formation depends on the rate of in-situ foam generation and the simulation consists in the fact that it is similar to the law of filtration with a limiting gradient. The paper discusses the process of quasi-periodic gas formation during the movement of mixing solutions in porous media. In stationary filtration in a homogeneous porous medium, the process is described by the proposed system of equations. A system of equations is proposed that describes the movement of a liquid taking into account adsorption of reagents, diffusion and dynamics of the foaming reaction. The results obtained can serve as the basis for developing a method for controlling the water cut of porous media during waterflooding of oil formations. This, in turn, leads to the leveling of the displacement front and an increase in the completeness of coverage.

The article discusses the results of assessing the influence of fiber reinforcement on the basic properties of cement mortars and the resulting stone. Its physical and mechanical properties and impact resistance after long-term hardening have been studied, which made it possible to evaluate cement deformation under the influence of applied stresses and predict the ability of cement stone to withstand these stresses at temperatures up to 100 °C.Portland cement hardening products undergo significant phase and microstructural transformations at high temperatures, accompanied by a decrease in strength (thermal corrosion), which intensifies at temperatures above 110 °C. At the same time, hardening products rich in calcium are formed in the cement stone, which leads to an increase in the permeability of the cement stone and a deterioration in its mechanical properties.The solutions considered in this work were formulated using Portland cement -Active-160 cement with the introduction of various types of fibers that improve the ability of the casing stone to withstand dynamic loads in the well.

Kitsch, Camp, and Cringe as the Agents of Profanation
Authors:   Independent scholar, St. Petersburg, Russia, Mikhaylova Liubov
Published: September 2024

The article is dedicated to the definition of the term “cringe” placed in the modern ethical and aesthetics discourses. The author claims that camp aesthetic, generally described in Notes on Camp by Susan Sontag, is the closest to cringe. To reveal their similarities, there is a following separation in the actual understanding of cringe, namely, cringe1 as a direct reaction of shame on something external, the basic definition of cringe; cringe2 as a deactivated or sublated cringe, meaning by sublation the moment of cringe being turned onto itself, collapsing and allowing people to stay themselves. Cringe2 is what the author compares with camp as an aesthetic of vulnerability and “failed seriousness,” while cringe1 reveals similarities with kitsch. Critical analysis of camp indicates that camp as a style still exploits vulnerability, therefore it doesn’t complete the therapeutic work it has started. As an alternative or post-camp aesthetics, the author proposes to highlight the conception of hypo aesthetics (Michael Kurtov) by which one may accept reality as it is. Based on texts by Giorgio Agamben Profanations and The Coming Community, the author comprehends cringe as an agent of profanation and an actor of liberation from dispositives of power. Unlike the other actor — parody, which is based on a distance to its subject, there is a fact of disappearance of this distance at the core of cringe. According to the author, this specificity of cringe allows the radically profane revelation to happen. Thus, transgression by the means of cringe becomes possible. An example of such transgression can be found in works by Georges Bataille and contemporary psychedelic cinema (Everything Everywhere All at Once, 2022).
The ‘Distance’ Stance. The Apparatus of Knowledge Production in Early Russian Artistic Research
Authors:   V–A–C Foundation, GES-2 House of Culture, Kononchuk Lera ,   National Research University — Higher School of Economics (HSE University), Moscow, Russia
Published: September 2024

The article examines the specifics of Russian artistic research. First, with the help of historical analysis of the phenomenon in the international context, the essential characteristics of artistic research are deduced. They consist in the intertwining of ontology, epistemology and methodology of a work or a process, which is enacted through a problem beyond the issues of art. Art in this situation acts as an “epistemic thing” (Henk Borgdorff), a “theoretical object” (Hubert Damisch), or an enactive environment. This boundary, or the interdependent intertwining of the subject, method, and purpose of the work, manifests itself in different ways in the various apparatuses of knowledge production in art, varying from context to context, despite the globalization of the art scene of the twenty-first century. The Russian art of the late noughties and early tens was just approaching the use of the research paradigm. Its application is conditioned by a range of reasons, including the need to construct a work of art as a complex reflection on a socially acute topic, such as issues of national identity and historical amnesia. The art segment under consideration tried to avoid merging with the common media imagery, moving away from both the dominant rhetoric and its ironic interpretations by artist predecessors and fellow contemporaries, while bypassing straightforward activist strategies. The kind of knowledge such art dealt with was often non-knowledge, the ungraspable, the erased, and the camouflaged. This knowledge found its elusive manifestation in traces of absence, scattered authorship, failures, and other forms of distancing, yet sometimes revealing through such embodiments its own communicative limitations.
10 Surprises of the War
Authors:   rench Institute for Demographic Studies (INED), Aubervilliers, France, Todd Emmanuel
Published: September 2024

This article is dedicated to the surprises that Russia’s Special Military Operation in Ukraine brought with it. The author counts ten such circumstances: the beginning of a full-scale war in Europe; the actual clash between Russia and the United States, despite the fact that for many years the United States considered China its enemy; fierce military resistance of Ukraine, despite its state of a failed state; Russia’s economic stability; the complete submission of the European Union countries to the political will of the United States; the unexpectedly active involvement of Great Britain and the Scandinavian countries as Russia’s major opponents in Europe; the weakness of the American military-industrial complex, unable to meet the military needs of Ukraine; the ideological loneliness of the West, whom not only China, but also the countries of the global South and the Muslim world refused to unconditionally support. The last surprise, according to the author, will be the impending defeat of the West. It will be a consequence of the its deep ongoing crisis. This crisis is primarily caused by the decline of the idea of the nation state in its classical form. In the case of the United States, it took the form of a post-imperial state formation. Thus, two mentalities collide in this conflict. On the one hand, the strategic realism of nation state, and on the other, the post-imperial mentality. Neither mentality fully understands the other. Russia does not understand that the West no longer consists of nation states, and the West has become immune to the idea of national sovereignty. However, this asymmetry works in Russia’s favor, since its stakes in this conflict are existential.
Time, Forward: Irreversible Events, Affect, and Future Narratives
Authors:   National Research University Higher School of Economics (HSE University), Moscow, Russia, Shulyatyeva Dina
Published: September 2024

Contemporary fiction and film are full of complex narrative forms. They attempt to make readers’ and viewers’ experience more perplexed, while also challenging and redefining the basic elements of narrative. The forking-path narrative also highlights the complexity of contemporary narrative forms: it presents a storyworld which encompasses multiple possible alternative worlds. Events within it can be either reversible or irreversible, and each time they remain unpredictable to the reader. The author examines the irreversibility of events in forking-path narratives on the example of the Paul Auster’s novel 4321. While reversibility of events emphasizes that the fabula can be changed in each storyline and, as a result, it becomes multiversion, irreversibility of events instead has a different effect. Irreversible events operate in forking-path narratives on the principle of repetition: they invariably recur in each storyline, and this recurrence enhances (more frequently a tragic) experience. The recurrence of irreversible events also creates a specific rhythm within the narrative. Such rhythmic patterns emerge at the narrative level and have a major role in shaping the reader’s experience, requiring bodily response, i.e. potentially resulting in bodily feelings. It constructs a mimesis which can be understood as “carnal” (in terms of Vivian Sobchack), with less mediation between storyworld and reader reality. The experience generated by irreversible events conflicts with another, shaped by reversible events, and together they generate the effect of a chaotic temporal movement, typical for narratives that can be regarded as “unruly” and “extreme,” with a versatile (and simultaneous) impact on the reader.

Introduction

Tinnitus is a condition that requires multidisciplinary care and monitoring. Widespread use of mobile devices and ready access to the internet offers a possible solution since smartphones can run apps programmed for a particular health problem. The aim of the article is to assess the scale and direction of how mobile apps are being created and used to diagnose and treat tinnitus.

Material and methods

Publications in Google Scholar, PubMed, and ResearchGate were searched for the years 2010–2023. The results of the review were organized by themes.

Results

Hits were organized into the following themes: (1) existing mobile apps for tinnitus, (2) apps supporting the diagnosis of tinnitus, (3) apps supporting tinnitus therapy, (4) a look to the future – sensors built-in or connected to mobile devices, wearables, artificial intelligence (AI), and big data systems.

Conclusions

Smartphone-based apps with ecological momentary assessment methods and the possibilities of using wearable diagnostic devices might be useful in better understanding the variability of tinnitus and perhaps its causes. Mobile crowdsensing and central databases with
big data and artificial intelligence support appear to be a valuable resource for new scientific research. There are now mobile apps providing a variety of therapies – sound therapy, self-help psychology, and educational training. Equally important for tinnitus therapy are smart devices managed by mobile apps – hearing aids, cochlear implants, and other hearables. In the future, development of mobile technologies and artificial intelligence will help create smart therapy platforms for tinnitus.

Published: September 2024

Composite-based structures are becoming increasingly common in aircraft construction. Its use is done to improve structural strength performance and weight loss of aircraft. Composite is divided into two manufacturing concepts, namely, composite sandwich and also composite laminate. The composite sandwich concept provides a method for obtaining high bending stiffness with minimal weight compared to laminate construction. The number of advantages obtained in composite sandwiches can’t be separated from the level of difficulty possessed in the process of making and repairing composites. This study examines the hazards caused in the manufacturing and repair procedures using the Job Hazard Analysis method.

This research is conducted under a fact that there is an irrelevant issue among expectation, process, and result achieved in the education. Therefore, teachers’ professionalism is highly needed to run teaching and learning activities.The purposes of this research are to 1) investigate to what extent teachers’ professionalism and students’ learning motivation can improve intellectual intelligence of the students in elementary schools in Pandeglang County, 2) investigate teachers’ efforts in improving intellectual intelligence of the students in the aforementioned schools.The method used in this research is descriptive method with qualitative approach. Meanwhile, the data source is gotten from an informant as a research subject with literature research and field research as data collection techniques by doing observation, documentation, and interview to some informants including teachers, students, and the schools’ headmasters. Next, the data isanalyzed carefully. The data show that teachers’ professionalism and students’ motivation to improve the intellectual intelligence of the students in the aforementioned schools still cannot be categorized as professional. It can be proven by the research findings where the students’ reading interest is still low. Data from 4 schools show that around 32.18% students are illiterate. The above-mentioned thing is a factor which dominates the lack of teachers’ professionalism in improving the students’ intellectual intelligence during the teaching and learning processes. It includes lack of teaching method, strategy, and skill. Therefore, the condition fails to trigger and stimulate the students’ learning interest. As a result, it can be concluded that the teacher’s professionalism is considered as less professional. KeywordTeacher’s Professionalism, Student’s Learning Interest, Student’s intellectual intelligence

Poverty is widely acknowledged as a significant factor in the outbreak of armed conflicts, particularly fueling armed conflict within national borders. There is a compelling argument positing that poverty is a primary catalyst for intrastate armed conflicts; reciprocally, these conflicts exacerbate poverty. This article introduces a statistical model to forecast the likelihood of armed conflict within a country by scrutinizing the intricate relationship between intrastate armed conflicts and various facets of poverty. Poverty, arising from factors such as gender inequality and limited access to education and public services, profoundly affects social cohesion. Armed conflicts, a significant cause of poverty, result in migration, economic devastation, and adverse effects on social unity, particularly affecting disadvantaged and marginal groups. Forecasting and receiving early warnings for intrastate armed conflicts are crucial for international policymakers to take precautionary measures. Anticipating and proactively addressing potential conflicts can mitigate adverse consequences and prevent escalation. Hence, forecasting intrastate armed conflicts is vital, prompting policymakers to prioritize the development of effective strategies to mitigate their impact. While not guaranteeing absolute certainty in forecasting future armed conflicts, the model shows a high degree of accuracy in assessing security risks related to intrastate conflicts. It utilizes a machine‐learning algorithm and annually published fragility data to forecast future intrastate armed conflicts. Despite the widespread use of machine‐learning algorithms in engineering, their application in social sciences still needs to be improved. This article introduces an innovative approach to examining the correlation between various dimensions of poverty and armed conflict using machine‐learning algorithms.

Aim. To describe a clinical case of transthyretin amyloidosis, the first manifestation of which was an episode of acute heart failure.

Materials and methods. Patient V., 58 years old, was taken to the intensive care unit for patients with myocardial infarction V.P. Demikhov State Clinical Hospital with a preliminary diagnosis: acute coronary syndrome without ST segment elevation, pulmonary edema. It is known from the anamnesis that the patient was disturbed for 3 months by a pronounced dry cough, hoarseness of voice, weakness with minor physical exertion.

Results. The complexity of the diagnosis of postmortem diagnosis of systemic amyloidosis was explained by the absence of any clinical manifestations that made it possible to suspect a deadly disease before hospitalization for pulmonary edema. This clinical case demonstrates the rapid development of symptoms of systemic amyloidosis. From the moment of the first symptoms (persistent dry cough, hoarseness of voice) to death as a result of heart failure, about 3 months have passed. The addition of peripheral polyneuropathy to the clinical picture made it possible to suspect a systemic disease.

Conclusion. This clinical case proves the relevance and importance of timely diagnosis of amyloidosis, as well as the need to raise awareness of doctors of various specialties about this disease.
