Methodology for taking into account the process of soil compaction when assessing the interaction of structures with the soil base using the finite element method
Authors: Lytvyn Oleksandr
Published: January 2025

During the interaction of structures with the soil base, the process of soil compaction under the foundations predominates, when irreversible deformations associated with a decrease in the volume of pores in the soil begin to develop. Usually, zones of plastic deformations associated with shear deformations will also arise, but they will be local, not large in size and do not significantly affect the redistribution of stresses in the “Base-Foundation-Building” system. Based on this, the article proposes a methodology for assessing the interaction of structures with the soil base under conditions close to compression pressing, which is based on the use of a mathematical model that describes the process of soil compaction and compression test data. The presented approach allows using data from oedometer soil tests conducted at small pressure ranges (0.1-0.3 MPa) to assess the interaction of foundations with the base of most modern structures such as high-rise buildings, industrial facilities and others, under which the pressure in the base only starts from 0.3-0.4 MPa.
To implement the method, the semi-logarithmic law of soil compaction of K. Tertsagi was chosen, which allows extending the compression curve obtained in laboratory conditions at small pressure values to the required pressure ranges with larger values and determining the deformation modulus in this wider pressure range. The method is implemented in the Simulia Abaqus environment using the user subroutine UMAT (user subroutine). It is shown that the results of numerical modeling are consistent with the data from laboratory tests. In addition, it was found that taking into account the process of soil compaction and the dependence of the deformation modulus on pressure allows you to practically eliminate the influence of boundary conditions on the stress-strain state of the "Base-Foundation-Superstructures" system, which is especially important when assessing the mutual influence of closely located structures with significantly different limits of the compressible layer. The advantage of the proposed approach is also that in addition to compression test data, other data on soil deformability obtained on more modern laboratory devices, such as a stabilometer, can also be used.

Published: January 2025

One of the most crucial and important points in the design of a structure is the calculation of the connection elements of the nodes, since the reliability of the structureas a whole depends on the accuracy and reliability of the calculation results. Designs chemesare often simplified to reduce labor costs in the calculation of node elements, but this approach sometimes does not allow for a full analysis of the distribution of forces, which can be critical forcerta in types of structures. The main types of joint are welded, riveted and bolted. Bolted joint have many advantages over other types, namely: high manufactur ability, reliability, and speed of installation work. The various approaches to modeling of bolted joint are considered and compired in this paper.
Currently, one of the most effective and least time-consuming means of numerical modeling of the stress-strain state of spatial bodies, including bolted joint, can be considered a semi-analytical finite element method (SFEM).
The bolt body, bolt head and nut were modeled by spatial elements, and the bolt tension was modeled by concentrated and distributed forces and the load from uniform heating, combining displacements in the nodes, and fixing displacements along the contour.
There sults obtained with different approaches to modeling bolt tensionallowustoconcludethatthereis a slight difference in the stress distribution in the spatial formulation of the FEM and SFEM and made it possible to detect discrepancies in the stressed state of the bolted joint for the case of taking bolt tensionin to account.
Energy-Based Assessment of the Ultimate Limit State of a Physically Nonlinear Structure
Authors: Perelmuter Anatolii , Perelmuter Mykhailo
Published: January 2025

The paper addresses issues of nonlinear analysis of load-bearing structural members. It highlights the main distinction from the traditional approach, which involves a two-step procedure where static and dynamic analyses are separated from the local reliability check of design sections. In contrast, the nonlinear analysis employs a single-step analysis and a global assessment of the structural behavior while simultaneously checking the performance of all sections.
It is proposed to use the work done by external forces as a measure for determining the ultimate load. An incremental procedure is analyzed, through which the equilibrium state curve is constructed and this work is calculated. The paper highlights the issue of numerical instability in the computational process as it approaches the failure load. As a way to address this problem, it is suggested to consider a state of the structure as ultimate when it significantly loses its ability to resist the increasing load (loss of resistance).
The paper proposes a method for finding design combinations of independent load cases, based on the energy approach, which offers sufficient applicability. It is noted that in the case of nonlinear (global) analysis, the selection of a design load combination should be based not on a local criterion but on a global one, which defines the composition of loads and actions constituting the design combination. The energy of deformation is suggested as such a criterion. The algorithm for searching for dangerous load combinations relies on a plausible hypothesis that the energy-based composition of load combinations leading the system to its ultimate state, due to the global nature of energy assessments, will be the same as in the case of linear analysis. This algorithm enables to solve the problem without resorting to an exhaustive evaluation of all possible load combinations.

Published: January 2025

There is a powerful mathematical apparatus which appeared up on the basis of the theory of Brownian motion of Markov processes and processes of diffusional type nowadays. It allows deciding intricate dynamic problems taking into account fluctuation processes. A classic result in this area is the article of O.O. Andronov, L.S. Pontryagin and O.A. Vitt, in which firstly the methods of the theory of Markov processes were applied to research of problems of statistical dynamics of the nonlinear systems. Later, the strict mathematical theory of stochastic differential equations of Ito was presented in an article of I.I. Gikhman and A.V. Skorokhodov. An important step in application of this theory to research of dynamic problems of the elastic systems was become researches of R.L. Stratonovich. These researches were based on combination of Krilov-Bogolyubov method of averaging with the method of theory of Markov processes. The strict ground of this approach was done by R.Z. Khasminski. A significant contribution to the development of the theory of stochastic systems and the introduction of probabilistic methods for the calculation of structures was made by V.V. Bolotin and his followers. V.V. Bolotin performed significant work on the application of probabilistic methods to the calculation of structures. Also important are studies of stochastic parametric oscillations of various systems by Dimentberg, V.I. Klyatskin and others. From the beginning of 80-th of the last century the scientists of Structural and Theoretical mechanics department of the Kyiv National University of Construction and Architecture were engaged in development of the numeral research of stochastic stability of elastic systems. Results of numerical researches of stability of parametric oscillations of the cylindrical and shallow shells under different stochastic influences were presented at this article. Parametric oscillations models of the shells were formed on the basis of the asymptotic or functional approaches and Monte-Carlo method using the calculation procedures of finite element analysis software. Stochastic stability of elastic shells was formulated as stability in probability, on average and with respect to the moment functions of different order. The critical values of stochastic load intensity and the regions of stochastic stability of shells were obtained by Runge-Kutta method of the fourth order and the continuation by parameter method.

Published: January 2025

The peculiarities of the oscillatory process of the bearing layers of three-layer conical shells depending on changes in the geometric and physical and mechanical characteristics of the material of their bearing layers at different properties of the polymeric filler material of the structure are investigated. Theсases of dynamic behavior of three-layer conical shells are considered and a comparative analysis of the parameters of the stress-strain state characteristics at different ratios of elasticity of the bearing layers of the structure and the polymer aggregate material is given.Taking into account the difference in the material parameters of the bearing layers and the distance between the reinforcing ribs of the structure exceeding the value of their cross section, the model of the shear theory of shells and rods by S. P. Timoshenko was used in the study.Finite-element modeling and numerical calculations of normal deflections and normal stresses of the bearing layers of the structure, which determine its stress-strain state, were performed.The influence of the elasticity of the polymer aggregate on the dynamic behavior of three-layer conical shells under non-stationary loading was evaluated.The article shows that by changing the material of the conical shell package, the thickness of the bearing layers and the elasticity of the aggregate, it is possible to select a structure design with the predicted dynamic behavior under non-stationary loading.The obtained results of the study of dynamic processes in the considered three-layer structures under different geometrical and mechanical parameters can be of significant interest for design developments.

Published: January 2025

Dyspnea is a common complaint in geriatric patients. Owing to a direct impact on physical, mental and social status, the symptom is of global
importance as a predictor of a decrease in life quality and expectancy in older people. In recent years, large focus on studies of general
pathophysiological mechanisms of dyspnea and cognitive dysfunction opens the potential for development of fundamentally new therapeutic
approaches to manage these clinical manifestations.
Aim: to analyze and to systematize relevant literature data on evaluation of mechanisms of cognitive dysfunction associated with the most
common geriatric conditions (i. e., chronic heart failure and chronic obstructive pulmonary disease) and a significant geriatric syndrome
(i. e., sarcopenia), which have close pathogenetic relationships and are united by a common symptom (i. e., dyspnea). Due to accumulated data
on a direct dyspnea effects on cognitive functions, a review of the most relevant data covering the issue aspect is also provided.
Several queries (keywords: "dyspnea", "cognitive dysfunction", "sarcopenia", "chronic obstructive pulmonary disease", and "chronic heart
failure") were used in the PubMed/MedLine, Sciencedirect, elibrary, and Cyberleninka search engines. More than 200 topically relevant
references have been processed, and the most significant data in the light of the issue discussed are reported in the paper.
The literature review is focused on cognitive dysfunction and dyspnea which are one of the most significant geriatric issues. Due to magnetic
resonance imaging visualizing pathomorphological brain changes, specific signs of degenerative changes corresponding to a decrease in
mental status were identified and described in detail. Cognitive impairment associated with chronic obstructive pulmonary disease and chronic heart failure has been described in some detail. Actually, the relationship between sarcopenia and cognitive dysfunction which is
discernible as in the case of the "slowing" phenomenon, is being studied; in recent years, available results of a number of studies confirm this
fact. The papers demonstrate the best evidence of a direct pathogenetic relationship between dyspnea and cognitive dysfunction, and this
offers the challenge to develop new therapeutic approaches to manage both abnormalities. Further comprehensive study of issues related to
cognitive dysfunction and dyspnea is of great importance for geriatricians and physicians of related specialties as it corresponds to the WHO
tasks and increases the chances of many older people at healthy aging.
Keywords: cognitive dysfunction, dyspnea, sarcopenia, chronic obstructive pulmonary disease, chronic heart failure.

Published: January 2025

Based on the research conducted in 2023, the paper addresses the issue of the housing of Zagreb students from an ethnological and cultural-anthropological perspective. The aim is to contribute to the understanding of students’ housing through a focused, in-depth and qualitative view of the material aspects of housing (selection, design/equipping/changing of domestic spaces, material objectsand furnishings of domestic spaces, etc.), everyday life, behaviour, practices and interactions linked with domestic spaces, and feelings and imaginations linked with the house and home. The research findings show that domestic space with its characteristics causes, limits or accentuates certain behaviours, interactions with roommates, feelings and moods. The examples discussed speak of the limitations and disadvantages of domestic spaces resulting from their often-inadequate size and furnishings, as well as about practices, often small interventions and furnishings, with which tenants try to overcome limitations, create a practical and pleasant space and achieve a pleasant coexistence withtheir roommates. Building a connection with the domestic space, creating intimacy and a sense of home are recorded in the actions of furnishing the space with their own objects, smells, sounds, and established activities and interactions with people and pets. The idea of future (and ideal) domestic spaces is associated with the idea of temporality (current housing), and the current and future place of residence is perceived as a space of becoming independent and independence. The aim of the paper is to pave the way for future extensive ethnological and cultural-anthropological research on housing.

Published: January 2025

In District 2 Banyu Asin (BNA) Pertamina Field Cepu there are 2 wells that function as Pumping Units (PU). This Pumping Unit uses an artificial Pumping Unit system with a Gas Engine. The location of these 2 pump-ing wells is very far from the source of the electricity network provided by PLN, so that for the operation of urgent lighting needs, generators are still used. The generator used has had a history of trouble which caused the power source to experience blackouts. This results in additional problems in operating the Pumping Unit if the generator power goes out at night. This study uses piezoelectricity, which is a component that can accumu-late an electric charge as a result of mechanical pressure. The energy generated by the piezoelectric will be stored in the battery via a boost converter. The battery will supply voltage and current to the lamp which will illuminate the location. In the process of charging the battery, the voltage will be stabilized by the PID system. The PID system will use the zieger nichols 2 method.

Proton therapy is a modality of radiotherapy that has a Bragg peak that can provide the correct radiation dose to cancer cells and minimize the dose to healthy tissue. In proton therapy, there is a passive scattering technique with a Range Modulated Wheel (RMW) in the form of a rotating wheel that scatters and compensates for the scattering effect. RMW has several steps, including lead and lexan. This study evaluated the depth of proton therapy dose on water phantom using passive scattering with various RMW steps. The study was conducted by simulation using the PHITS Version 3.34 program. The geometry of the passive scattering nozzle and water phantom was simulated by entering RMW step data to obtain the dose depth. Based on the simulation results in step 1, the thickness of the lexan was thinner, resulting in a more extended dose range and higher dose. In contrast, in step 6, the thickness of the lexan was increased, resulting in higher scattering, which could reduce the dose and depth range.

СОЦІОЕКОНОМІЧНА СПРЯМОВАНІСТЬ ОСВІТНІХ ПРАКТИК У СФЕРІ АГРОЕКОЛОГІЇ
Authors: Федорова К. О. , Яровий В. Д.
Published: January 2025

Дослідження орієнтоване на оцінювання соціоекономічної спрямованості формальних агроекологічних освітніх практик в Україні. Показано, що офіційні освітні програми в навчальних закладах вищих рівнів акредитації в частинах, що стосуються агроекології, не висвітлюють всебічно її різні аспекти та орієнтовані переважно на здобувачів освіти за кваліфікаціями технологічного спрямування. Обґрунтовано доцільність переосмислення агроекологічних дисциплін в напрямку більш повного охоплення всіх проявів агроекології як суспільно-економічного феномену для підвищення обізнаності майбутніх фахівців з питань соціоекономічних аспектів агроекології, комплексного розуміння її соціально-економічних звʼязків та ефектів, які охоплюють значно ширший діапазон, ніж виключно технологічні аспекти.

КОНТРОЛЬ ЗА ВЧИНЕННЯМ ЗЛОЧИНУ У ФОРМІ КОНТРОЛЬОВАНОЇ ПОСТАВКИ
Authors: Гук Т. І.

Метою контрольованої поставки є виявлення, запобігання, припинення, розкриття злочинів і осіб, які їх готують або вчинили, забезпечення кримінального судочинства, а також здобуття інформації про події або дії, що становлять загрозу державній, військовій, економічній або екологічній безпеці України. Контрольована поставка, як форма контролю за вчиненням злочинів полягає в допущенні перевезення через кордон або всередині країни предметів та/або речовин, обіг яких обмежено під контролем правоохоронних органів з метою викриття та затримання як окремих правопорушників, так і учасників злочинних угруповань. Відомчі нормативні акти МВС України визначають контрольовану поставку як оперативно-розшуковий захід, що здійснюється в рамках оперативно-розшукових справ до початку кримінального провадження. Встановлено, що контрольована поставка полягає в організації та здійсненні оперативним підрозділом контролю за переміщенням (перевезенням, пересиланням, передачею, ввезенням, вивезенням з України або транзитним переміщенням її територією) товарів, предметів і речовин, включаючи заборонені до обігу, з метою виявлення ознак злочину та фіксації фактичних даних про протиправні дії осіб, відповідальність за які передбачена Кримінальним кодексом України. Контрольована поставка, наприклад, зброї або наркотиків, є своєрідною формою провокації злочину і має ознаки суспільно небезпечного діяння. На думку деяких дослідників, вона мало чим відрізняється від дій, передбачених КК України, таких як провокація давання хабара. Крім того, такі дії є занадто ризикованими.
