В отечественной и зарубежной специализированной литературе отсутствуют исследования, посвященные изучению факторов риска развития неблагоприятного исхода у пациентов старшей возрастной группы с инсультассоциированной нозокомиальной пневмонией. Цель исследования - изучение факторов риска развития неблагоприятного клинического исхода у пациентов пожилого и старческого возраста с нозокомиальной пневмонией на фоне ОНМК. В исследование были включены 247 пациентов пожилого и старческого возраста (139 мужчин, 108 женщин, средний возраст - 74,1±6,3 года), госпитализированных с признаками ОНМК по ишемическому или геморрагическому типу. Согласно модели бинарной логистической регрессии, статистически значимо ассоциированы с развитием неблагоприятного исхода у изучаемой группы респондентов следующие параметры: возраст свыше 75 лет (p=0,011), степень инвалидизации по шкале mRS 3 (р=0,009), а также уровень С-РБ >100 мг/л (р=0,023) и мочевины >7 ммоль/л (р=0,044). Для снижения частоты встречаемости неблагоприятного клинического исхода у пациентов старшей возрастной группы с инсульт-ассоциированной нозокомиальной пневмонией необходимо верифицировать перечисленные выше клинико-лабораторные параметры на ранних этапах госпитализации.

In the domestic and foreign specialized literature, there are no studies devoted to the study of risk factors of mortality in the older age patients with stroke-associated nosocomial pneumonia. The purpose of the study was to study the risk factors of adverse clinical outcomes in elderly and senile patients with stroke-associated nosocomial pneumonia. The study included 247 elderly and senile patients (139 men, 108 women, mean age - 74,1±6,3 years) who were hospitalized with signs of ischemic or hemorrhagic stroke. According to the binary logistic regression model, the following parameters are statistically significantly associated with adverse clinical outcomes in the studied group of respondents: age over 75 years (p=0.011), degree of disability according to mRS ≥3 (p=0,009), and C-reactive protein levels over 100 mg/l (p=0,023) and urea more than 7 mmol/l (p=0,044). In order to reduce the incidence of adverse clinical outcomes in patients of the older age group with stroke-associated nosocomial pneumonia, it is necessary to verify the above clinical and laboratory parameters at the early stages of hospitalization.

В статье рассмотрен феномен «внутриутробного программирования», в значительной степени определяющий дальнейший жизненный цикл и вероятность развития ряда возраст-ассоциированных патологических процессов. С позиций современной науки при использовании большого литературного материала обсуждается возможность формирования патологического (ускоренного) старения на самых разных этапах онтогенеза. В тесной взаимосвязи обсуждаются причины, механизмы и фенотипические проявления ускоренного старения и возможности ранней, начиная с перинатального периода, диагностики и прогнозирования возраст-ассоциированных патологий.

This article examines the phenomenon of «intrauterine programming», which largely determines the further life cycle and the likelihood of developing a number of age-associated pathological processes. The possibility of the formation of pathological (accelerated) aging at various stages of ontogenesis is discussed with the use of large literary material from the standpoint of modern science. The reasons, mechanisms and phenotypic manifestations of accelerated aging and the possibilities of the earliest one, its diagnosis starting from the perinatal period, and prediction of age-associated pathologies are discussed in close interrelation.

Published: September 2021

Salinity, which is a significant abiotic stress factor, is among the most important factors that limit product quality and yield. In this study investigated phenological and physiological changes that occurred in three different safflower varieties that were exposed to KCl stress at concentrations of 0, 50, 100 and 150 mM. It was found that, based on increasing salt concentrations, the most significant decrease was in all phenological parameters at the concentrations of 100 and 150 mM KCl. The SOD and CAT activities showed a significant increase at high salt concentrations in the Balcı and Dinçer varieties. The APX and GR activities showed a parallelism in all safflower varieties, and they showed a significant increase based on increased concentration at the applications of 100 and 150 mM KCl. Among the three safflower varieties, the most resistant variety to salt application was Dinçer, while the most sensitive one was Remzibey. The Balcı variety was closer to the Dinçer variety in terms of its tolerance against salt stress.

This study aims to evaluate the behavior of ASTM A653 CS-A G90 steel in the process of Incremental Sheet Forming – ISF, based on the following parameters: diameter of the tool (Dt in mm) and the vertical step size between consecutive contours (∆z in mm). The experiments were based on a variation of the ISF process, called Single Point Incremental Forming - SPIF. In this study, seventeen tests were conducted using a punching tool with diameters (Dt ) of 5, 6 and 8 mm and vertical steps (∆z) of 0.4, 0.6 and 0.8 mm, intending to evaluate the true strain to the ISF process and the surface finishing measured by roughness parameter (Rz). Whereas, for the execution of practical testing, the resources used were a CNCmachining center with three axes, tools for incremental forming and a sheet-press device. As a result, greater depths were achieved using an incremental step of 0.4 mm. In additional tests, it came to attention that the diameter of the tool was also an important parameter when it is desired to increase the formability and greater depths are obtained when using small diameters. It can be observed yet, there is a tendency to increase the roughness parameter Rz when using greater vertical steps ∆z

Published: September 2021

The present work aims to evaluate the influence of different residue incorporations on the physical and mechanical properties of a typical red ceramic composition, replacing the sand, by using the residue from the first stage of tempered glass manufacturing. Ceramic specimens were prepared with incorporations of 0 and 20% of flat glass waste. The samples were obtained by extrusion, dried and fired at 800, 900, 1000 ° C in a laboratory oven. Analyzes of the raw materials were performed, among which the thermal, morphological, physical and chemical can be highlighted. Tests on the fired ceramic specimens were also performed. The firing properties obtained were the dry bulk density, relative density, water absorption, dry linear shrinkage, linear firing shrinkage and flexural strength. The results showed that both the increase of the glass content and the increase of temperature had a positive influence on the studied properties. Furthermore, it confirmed that the glass waste acted in order to lower the proper firing temperature. Flat glass waste is therefore a highly recommended fluxing element for the red ceramic industry, as it can be incorporated in quantities as significant as 20% without major negative effects on the properties, therefore optimizing the amount of waste used and acting positively on the properties studied, reducing energy and raw material costs.

Published: September 2021

The present study has as a research theme the pollution of the national maritime waters caused by the operations of extraction, storage and transport of oil and its derivatives. Its general objective is to analyze how the understanding of the causes of pollution arising from the extraction, storage and transportation of oil and its derivatives helps to reduce the contamination of the Brazilian maritime waters, thus contributing to the improvement of the quality of these waters. It is the result of a bibliographical research based on the works of Eliane M. Octaviano Martins 2007 and 2009. Thus, the first chapter showed that accidents with oil spills are considered to be more harmful to the environment compared to other types of pollution in the sea. In addition, human error was highlighted as the most important error in maritime accidents and was related to the poor training of the professionals involved in the operation. The study facilitates understanding of the major flaws in the prevention of marine pollution from oil spills and shows the importance of risk management. It addresses the Brazilian position regarding international maritime safety standards and prevention of the marine environment. It evidences the importance of controlling the damage caused by an oil spill accident through efficient response in a timely manner to the distress. It exposes the condition of Brazil in the IMO, some Brazilian legislation and IMO codes and conventions. It shows how many standards are developed for the purpose of responding to major accidents both nationally and internationally. It demonstrates the harm caused by the lack of speed in enacting laws and enforcing standards. It presents some unilateral measures, some regional agreements and their effects. The overall goal is achieved through specific objectives. The paper concludes that oil production has sufficient economic and social relevance to assume its risks and that prevention of pollution is the best way to improve the quality of the Brazilian marine environment.

Impacto de la administración de la demanda en mercados emergentes
Authors: Rodríguez Marín Mauro
Published: September 2021

Este artículo pretende contribuir al análisis del impacto de la administración de la demanda (AD) en los últimos años en mercados emergentes (ME). Las empresas manufactureras y comercializadoras juegan un rol de vital importancia en la economía de los ME. Por tanto, es importante la implementación y sistematización de procesos tales como la AD, con miras a la optimización de recursos, mejorar el servicio al cliente, la coordinación con proveedores y, en general, a la gestión de la cadena de suministro. De esta manera, se contribuye a que las empresas permanezcan en el mercado y sean cada vez más competitivas, lo que reduce la incertidumbre e incrementa sus ingresos, al adaptarse a condiciones favorables con el medio ambiente. En los últimos años se ha reconocido a la AD como el primer eslabón de la cadena de suministro de las empresas productoras, sin embargo, puede variar entre países desarrollados versus países emergentes. Esto nos hace pensar que existen procesos o mecanismos implícitos que no se han considerado preponderantes o que no son necesariamente homogéneos entre bloques de países. Es indiscutible la necesidad de dominar el conocimiento científico pasado y presente sobre el tema, a fin de aportar nuevos saberes y una contribución original.

Measuring Vibration parameter for rotating machinery is essential for monitoring and diagnosis system in industrial plants. This paper demonstrates another approach to vibration measurement for rotating machine using electrostatic sensor and signal processing techniques. A single electrostatic sensor is used to detect charges surrounding the moving shaft of the machine. The signal from the electrostatic sensor is processed in MATLAB using Autocorrelation, Fast-Fourier, and Root Mean Square. The implementation of this technical approach was conducted on a modified test rig using three different shafts. The three shafts represent three different vibration modes: normal, abnormal, and severe. Each shaft was experimented under low and high rotation speed to observe amplitude and frequency level. Although the results of the tests did not show a direct measure of vibration displacement, due to the complex nature of the induced charges by the surface pattern. However, the results showed an indicative level of vibration at different amplitudes for the three shafts.
Non-Parametric Bayesian Subspace Models for Acoustic Unit Discovery
Authors: Ondel Lucas
Published: September 2021

This work investigates subspace non-parametric models for the task of learning a set of acoustic units from unlabeled speech recordings. We constrain the base-measure of a Dirichlet-Process mixture with a phonetic subspace---estimated from other source languages---to build an \emph{educated prior}, thereby forcing the learned acoustic units to resemble phones of known source languages. Two types of models are proposed: (i) the Subspace HMM (SHMM) which assumes that the phonetic subspace is the same for every language, (ii) the Hierarchical-Subspace HMM (H-SHMM) which relaxes this assumption and allows to have a language-specific subspace estimated on the unlabeled target data. These models are applied on 3 languages: English, Yoruba and Mboshi and they are compared with various competitive acoustic units discovery baselines. Experimental results show that both subspace models outperform other systems in terms of clustering quality and segmentation accuracy. Moreover, we observe that the H-SHMM provides results superior to the SHMM supporting the idea that language-specific priors are preferable to language-agnostic priors for acoustic unit discovery.

Authors: Bhatnagar Dr. Pratik
Published: September 2021

Aim: To assess and compare the impact of reinforcement of PMMA with glass fibre, polyethylene fibre and carbon fibres on flexural strength, fracture toughness and abrasive resistance.

Background: In view of inadequate mechanical and physical characteristics of PMMA which include low impact strength and low surface hardness and resulting lowered clinical performance of the prosthesis, the study was designed to investigate the impact of reinforcement of PMMA with glass, polyethylene and carbon fibers on flexural strength, fracture toughness and abrasive resistance.

Methods and Findings: Rectangular specimens (n=120; 30 each from 4 groups; 65 × 10 × 3.3 mm3) were fabricated and loaded on Universal Testing Machine until fracture for flexural strength and fracture toughness and on Taber Abrasive Tester for abrasive resistance. Data were analyzed using one–way ANOVA followed by Post Hoc test - Bonferroni multiple comparison analysis, using significance level of 0.05. Significant increase in fracture toughness was observed in specimens reinforced with polyethylene and carbon fiber, albeit the values of flexural strength were increased insignificantly. Specimens reinforced with glass and carbon fiber had significantly low values of abrasive resistance.

Conclusion: Findings indicate that reinforcement of PMMA by non-specific fibers like glass, polyethylene and carbon resulted in significant increase in fracture toughness and decrease in abrasive resistance.
Paediatric Inflammatory Multisystem Syndrome Temporally Associated with Sars-Cov-2: A Review and Our Experience in a Secondary Hospital in Spain
Authors: Barberá Dr. Sergio Huerta
Published: September 2021

Introduction: Paediatric multisystem inflammation syndrome temporally associated with SARS-COV-2 (PIMS-TS was described in 2020 as an increased incidence of paediatric patients with cardiogenic shock and acute myocarditis associated with SARS-COV2. This disease has similarities and can manifest as Kawasaki Disease (KD). The aim of the study was to document the cardiovascular characteristics of the novel multisystem inflammatory syndrome in children and to share our experience.

Methods: A descriptive study is presented including children with diagnosis of PIMS- TS at a secondary hospital. Children 0 to 15 years of age admitted to a hospital between from May 2020 to May 2021 were included and the data, including demography, clinical status, biochemical markers, echocardiography findings, treatment and evolution, were extracted from the clinical history of the patients.

Results: 7 children were included from a secondary hospital. The mean age was 8 years and 71% were boys. The most common cardiovascular complications were cardiovascular shock with hypotension and the reduction in over a half of the patients in the left ventricular ejection fraction was reported. It was observed a high elevation of acute phase reactants at the admission. In 2 children were found coronary alterations. Polymerase chain reaction (PCR) for SARS-COV-2 was positive in 28% whereas immunoglobulin G (IgG) was positive in 100% cases.

Conclusion: Covid-19 disease is asymptomatic in children in most cases but cardiovascular involvement is common if PIMS-TS is presented. Despite the need of intensive care support, mortality is uncommon and our study shows that these patients can be treated in a hospital with Paediatric Intensive Critical Unit level 2 benefiting from combined, specific treatment.
Myocardial Ischemia During Off-Pump Coronary Artery Bypass Grafting – A Clinical Study
Authors: Mathur Anirudh
Published: September 2021

Objective: To evaluate relation among trans-esophageal echocardiography (TEE), biochemical and hemodynamic parameters which could possibly help in early detection of myocardial ischemia.

Design: Prospective observational, single centre study.

Participants: Patients diagnosed with coronary artery triple vessel disease undergoing Off-pump Coronary Artery Bypass Grafting (OPCAB).

Results: Statistically significant changes in Coronary Sinus (CS) pH and lactate levels were observed during lateral wall grafting, as well as the highest proportion of new regional wall motion abnormalities observed which signify the presence of a substantial level of myocardial ischemia during this time. We found a significant rise in HR (Heart Rate) as well as CS lactate following lateral wall grafting which correlated with the other parameters indicating substantial ischemia occurring during grafting of that territory. Maximum lactate clearance was found during anterior wall grafting and minimum after inferior wall grafting. This signifies that maximum lactate accumulates after anterior wall grafting, signifying greater extent of myocardial ischemia. Statistically significant rise in (CVP/RAP) (central venous pressure, right atrial pressure was noted) during grafting of all coronary territories, but the maximal rise was seen at the end of lateral wall grafting, followed by grafting of posterior basal wall.

Conclusions: Biochemical changes in form of rise in lactate and fall in CS pH doesn’t occur in absence of obvious hemodynamic derangements. Therefore, it is difficult to detect myocardial ischemia before any hemodynamic instability.
Diverticulum of Kommerell with Micro Aneurysm, an Aberrant Right Subclavian Artery and Ventricular Septal Defect in a 39 Years Old Female: Case Report
Authors: Bian Xiaoming
Published: September 2021

Diverticulum of Kommerell is a congenital anomaly in the development of the primitive embryonic aortic vasculature resulting in either an aberrant left subclavian artery (ALSA) from a right-sided aortic arch (RSAA) or an aberrant right subclavian artery (ARSA) from a left-sided aortic arch (LSAA). Kommerell’s diverticulum (KD), is extremely rare in the general population having prevalence of 0.7–2.0 %. KD with true aneurysmal dilatation like any vascular lesion of the thoracic aorta weakens the vasculature and increases the risk of aortic rupture. Timely surgical intervention is of paramount importance in most of these cases. Variable clinical presentations in patients with KD are either a result of compression of some mediastinal organs or strangulation by the vascular ring from the aberrant subclavian artery (ASA). We report a case of a 39 years old Chinese female with a rare co-existence of a huge KD with a microaneurysm, an aberrant right subclavian artery (ARSA), and ventricular septal defect (VSD). She underwent a successful operation and all her pre-surgical symptoms disappeared.
Turán Density of $2$-Edge-Colored Bipartite Graphs with Application on $\{2, 3\}$-Hypergraphs
Authors: Bai Shuliang , Lu Linyuan
Published: September 2021

We consider the Turán problems of $2$-edge-colored graphs. A $2$-edge-colored graph $H=(V, E_r, E_b)$ is a triple consisting of the vertex set $V$, the set of red edges $E_r$ and the set of blue edges $E_b$ where $E_r$ and $E_b$ do not have to be disjoint. The Turán density $\pi(H)$ of $H$ is defined to be $\lim_{n\to\infty} \max_{G_n}h_n(G_n)$, where $G_n$ is chosen among all possible $2$-edge-colored graphs on $n$ vertices containing no $H$ as a sub-graph and $h_n(G_n)=(|E_r(G)|+|E_b(G)|)/\binom{n}{2}$ is the formula to measure the edge density of $G_n$. We will determine the Turán densities of all $2$-edge-colored bipartite graphs. We also give an important application on the Turán problems of $\{2, 3\}$-hypergraphs.

Published: September 2021

In this paper we introduce and study a type of Cayley graph – subnormal Cayley graph. We prove that a subnormal 2-arc transitive Cayley graph is a normal Cayley graph or a normal cover of a complete bipartite graph $\mathbf{K}_{p^d,p^d}$ with $p$ prime. Then we obtain a generic method for constructing half-symmetric (namely edge transitive but not arc transitive) Cayley graphs.
Academic Performance and Procrastination: The Case of Education Students in MSU-Sulu
Authors: Anuddin Fermina Omar
Published: September 2021

This kind of attitude among the university students stems out of laziness and lack of prioritization in their academic endeavor. Research says that 95% of American students purposely delay beginning or completing tasks and 70% engaged in academic procrastination. It is not impossible that Filipinos are actually expert in procrastination. In other words, procrastination largely accounts for the relationship of conscientiousness to performance, and that procrastination is strongly associated with distractibility, poor organization, low achievement motivation, and an intention-action gap. If one is not conscientious in his performance he will likely engage in procrastination. Additionally, agreeableness and sensation seeking traits generated low correlations with procrastination. One possible way to decrease procrastination for tasks is to increase expectancy of success, or self- efficacy by verbal persuasion, emotional arousal, and modeling. Despite of the advances in the education nowadays, and the challenging tasks that students faced day by day to cope up with the requirements of their respective courses, they are still in the realm of seemingly taking their studies for granted that as if it’s easy or simply put, procrastinating! In connection, it sought to answer this question: Is there a relationship between procrastination to the academic performance in GEC 104 (Mathematics in the Modern World) of the 2nd year students of the College of Education at Mindanao State University-Sulu?
Economy, Education and Physical Education in Kenya in the Light of Statistical Indicators.
Authors: Hideg Gabriella
Published: September 2021

Kenya was once a British colony, and today it is a fast-growing country with world-class hotels and shopping malls on one side of the road, while misery and poverty show their cruel faces on the other side. It is a country where internal struggles and political unrest are ongoing, corruption is enormous, and an increasing number of terrorist organizations are appearing (even breaking into universities and slaughtering young people for their religious affiliation). The aim of our work is to present the economic, social, and socio-cultural background of the country. We considered it important to highlight economic indicators such as the proportion of GDP spent on education at each level of the education system, alone and compared to other countries, and we also examined the population pyramid of the country. One of the interesting points of the study is the comparison of Kenya's educational values with those of Malaysia or Africa, and also specifically mapping the physical education development of Kenya. In the course of our research, we relied on the available literature and the analysis of statistical data, however, personal experiences and observations are interspersed with the study. As a result of our work, we can get a clearer picture of the economic, social, and socio-cultural environment of a wonderful country, thus bringing the values of a distant world closer.

Habrosia (Caryophyllaceae) a monotypic genus endemic to Western Asia
Authors: Iamonico Duilio
Published: September 2021

Habrosia (Sagineae, Caryophyllaceae) is a genus that includes only H. spinuliflora, a species occurring in Iran, Iraq, Syria, Lebanon, and Turkey (Irano-Turanian floristic chorological element). Based on the available molecular data published in 2011, Habrosia appears to be nested in a Minuartia-clade, which includes taxa currently recognized under the genus Sabulina. Consequently, Habrosia should be treated as a genus to be included in Sabulina. However, the molecular tree published in 2011 considered only 9 Sabulina members whereas, according to the current concept, Sabulina is a genus comprising about 65 species. Unfortunately, the molecular phylogeny including a larger Sabulina sample published in 2014 did not include H. spinuliflora and the taxonomic position of Habrosia remains, therefore, uncertain. With the aim of verifying the correct position of Habrosia in the tribe Sagineae with respect to its relationship to Sabulina, a comprehensive molecular investigation based on ITS sequences, linked to detailed morphological data, is presented. The results obtained revealed that Habrosia is not part of Sabulina. A detailed description of H. spinuliflora, its ecological preference, and a distribution map are provided. Eventually, the name Arenaria spinulifolia (basionym of H. spinuliflora) is lectotypified on a specimen preserved at G (barcode G00212963).

Published: September 2021

El objetivo es conocer y establecer algunas distinciones acerca de cómo se desempeñaban en sus aprendizajes los estudiantes de educación física antes de la pandemia y ahora en la virtualidad. Se profundizó en las funciones ejecutivas. Se trabajó con 46 estudiantes que cursan Psicología Educacional en Educación Física, de la Universidad Nacional de Río Cuarto, Córdoba, Argentina. Se utilizó una versión adaptada de EFECO (Ramos-Galarza et al., 2016). Los resultados evidencian tendencias de peor manejo en tiempos de pandemia respecto al monitoreo, inhibición, flexibilidad cognitiva, control emocional, iniciativa y memoria de trabajo. En la virtualidad aparecen dificultades de atención, organización, conectividad, vínculos, estados de ánimo, angustia y sueño.
Edipo femenino y Electra
Authors: Morales Monica
Published: September 2021

Como sucede en cualquier disciplina que se divulgue, no tardan en aparecer en escena nociones provenientes del sentido común que se infiltran en un afán simplificador; este es el caso del llamado “complejo de Electra” en psicoanálisis tan difundido incluso hasta en la Real Academia Española (RAE). La propuesta de este escrito es examinar las propuestas principalmente de Sigmund Freud y Jacques Lacan, quienes elaboran supuestos teórico-clínicos sobre el Edipo femenino, perfilando su rol en la estructuración psíquica de la mujer; y desentrañar el magnificente personaje de Electra en su esencia psicológica-literaria.
Сargo carrying capacity calculation for combined ships in optimization problem for ship’s main elements
Authors: Gulyaev Ilya A. Gulyaev , Ronnov Evgeniy P. Ronnov
Published: September 2021

This article is devoted to the development of the cargo carrying capacity evaluation method for a combined ship of tanker/platform type. A specific feature of cargo carrying capacity calculation for such ships lies in the fact that they have two cargo compartments of different structure. The compartments are interconnected, including dimensions, and influence each other. This fact leads to the need to update the existing calculation methods when justifying the main dimensions both of tankers and of platform ships. It is proposed to include the parameters which affect the cargo carrying capacity and take into account the above mentioned influence into the cargo carrying capacity equations. This article also specifies the determination methods for these parameters in the early stages of ship designing. All this made it possible to obtain relations, the inclusion of which into the mathematic model of optimization problem for main elements of a combined ship (tanker/platform type) allows proper evaluation of all available options of main dimensions in terms of their compliance with carrying capacity for each specific cargo as well as exclusion of improper options from consideration.

Published: September 2021

In work the fact of an essential increase of structure of cargo fleet of the internal and mixed a river sea navigation by vessels with nonconventional forms hulls is noted. On the basis of these CAE tests the analysis of nature of contact of such vessels with the water ice environment at the movement in the ice channel is carried out. Qualitative features of such contact of bulbous vessels with ice cakes and small ice cakes are noted. Special attention is paid to a research of influence of bulbous nasal points of different types on change of level of longitudinal ice hull loads and distribution of ices in a zone of their propeller systems. Statistical processing of the obtained experimental data on impact assessment of ice, dynamic and constructive factors on inertial characteristics of vessels with nonconventional forms hulls is carried out. The quantitative predict of such influence in the form of an empirical method of assessment of ice inertial characteristics of the studied fleet is given.

A study was carried out on the possibility and necessity of operating houseboats in the water areas of Russia on the basis of the concept of the development of reservoirs and small rivers, which is currently being developed by the state within the framework of national programs. A review of the operational, overall, displacement characteristics of houseboats was carried out with consideration of various options for ship power plants, suitable for the class of floating craft with registration in the State Inspection of Small Vehicles. The use of a stationary engine (JSC AvtoVAZ) in a configuration with a hydraulic drive and a swing-out column is proposed. Calculations of the resistance of the houseboat platform hull were made using several methods. A mechanism for the choice of propellers using a free software product according to empirical methods is proposed. An alternative drive scheme is selected, a detailed model of the working process of a houseboat's hydraulic drive is selected, and a mathematical model of its operation is presented.
