Determination of Temperature Stresses during Construction of the Monolithic Thick-Walled Cylindrical Shells
Authors: Zoalkfl D. A. , Turina V. S. , Chepurnenko A. S. 
Published: July 2024

Introduction. The thick-walled cylindrical shells are widely used in the hydraulic structures, protective structures of nuclear power plant reactors and missile system launchers. Due to the internal heat emission of concrete in massive monolithic structures, there is a high risk of early-age cracking. Computer modeling methods can be used to develop the preventive measures against it. Previously, modeling of temperature stresses within a construction process was carried out for the massive foundation slabs and walls, whereas the thick-walled cylindrical shells were not studied. The aim of the present work is to develop a methodology for calculating the temperature stresses during construction of the monolithic thick-walled cylindrical shells. Materials and Methods. Stress calculations were made in a one-dimensional axisymmetric formulation. The dependence of the mechanical properties of concrete on the degree of its maturity was taken into account. The stress-strain state (hereinafter — SSS) calculation problem was reduced to a second-order differential equation relative to the radial stress, which was solved numerically by a finite difference method. The SSS calculation was preceded by the temperature field calculation, which was deemed independent from the stress state. The authors carried out the numerical solution in the MATLAB environment.Results. At the first stage of testing, the developed methodology was compared with calculations made in the ANSYS software package under a time-constant modulus of elasticity of concrete that confirmed its reliability. Also, the calculation results, which took into account the dependence of the modulus of elasticity of concrete on degree of its maturity were presented. Moreover, compared to calculations under the time-constant mechanical properties of concrete, in the stress-strain state, the picture became radically different. Discussion and Conclusion. Calculations under a time-constant modulus of elasticity of concrete by means of the standard software packages, as opposed to the author’s methodology, leads to the overestimated circumferential stress values, and hinders calculation of the residual stresses. In the case of a time-constant modulus of elasticity of concrete, the temperature stresses are completely reversible.

Published: July 2024

Introduction. The formation, functioning and development of a civilized civil society with the well-established institutions of democracy is impossible without compliance with the acting values of law, reliance on the law legitimacy regime and legal order consistency. It is worth to emphasise that the interaction between the civil society and the law-governed state, launching the integration of the legal values into the fundamental social relations and the legal order potential, can be carried out only based on the mature democracy. This determines a favourable legal environment enabling a person and a citizen to gain rights and freedoms of his priority. The involvement of the legal instruments is vitally important in such spheres of political and social reality where the rights, freedoms and legal obligations of the society members are fulfilled. The aim of the study is to identify the influence of the legal values on the legal order in the context of the democratic regime and civil society development.Materials and Methods. The article analyses the values of law in the context of the public life democratisation. In the research the general scientific as well as specific scientific methods were used, such as: dialectical, system analysis, axiological, legalistic, comparative law and others.Results. The role of the democratic Constitution of the country as a major component of the legal value system is substantiated. The features of the legal value system and the legal order potential, intermediating the state of equality, freedom, legal activity in the leading spheres of political, social, and legal reality, were analysed. It is concluded that the full-fledged functioning of the civil society and the decent living of its members are mainly determined by the legal value system and consistent legal order. The legal values efficiency is distinctly manifested only through the successful functioning of the civil society institutions and authorities, through fulfilment of the human rights and freedoms.Discussion and Conclusion. Many vital problems of the civil society cannot be solved separately from the law. The problems of the legal regulation and attempts of the state to take control over the purely public spheres of the society members’ lives are revealed. It is proposed to focus on the need to clearly define the boundaries of the social and legal order, to use rationally the regulatory potential of both the norms of law and the social conduct norms.

Abstract

Purpose
This paper reports on a scientometric analysis bolstered by human-in-the-loop, domain experts, to examine the field of metal-organic frameworks (MOFs) research. Scientometric analyses reveal the intellectual landscape of a field. The study engaged MOF scientists in the design and review of our research workflow. MOF materials are an essential component in next-generation renewable energy storage and biomedical technologies. The research approach demonstrates how engaging experts, via human-in-the-loop processes, can help develop a comprehensive view of a field’s research trends, influential works, and specialized topics.

Design/methodology/approach
A scientometric analysis was conducted, integrating natural language processing (NLP), topic modeling, and network analysis methods. The analytical approach was enhanced through a human-in-the-loop iterative process involving MOF research scientists at selected intervals. MOF researcher feedback was incorporated into our method. The data sample included 65,209 MOF research articles. Python3 and software tool VOSviewer were used to perform the analysis.

Findings
The findings demonstrate the value of including domain experts in research workflows, refinement, and interpretation of results. At each stage of the analysis, the MOF researchers contributed to interpreting the results and method refinements targeting our focus on MOF research. This study identified influential works and their themes. Our findings also underscore four main MOF research directions and applications.

Research limitations
This study is limited by the sample (articles identified and referenced by the Cambridge Structural Database) that informed our analysis.

Practical implications
Our findings contribute to addressing the current gap in fully mapping out the comprehensive landscape of MOF research. Additionally, the results will help domain scientists target future research directions.

Originality/value
To the best of our knowledge, the number of publications collected for analysis exceeds those of previous studies. This enabled us to explore a more extensive body of MOF research compared to previous studies. Another contribution of our work is the iterative engagement of domain scientists, who brought in-depth, expert interpretation to the data analysis, helping hone the study.

Abstract
The main objective of this research work is to examine the way knowledge management (KM) affects organisational agility in an industrial company. To this end, the staff of Bosch Car Multimedia in Braga was chosen as the study population. This study is descriptive in terms of methodology; from the perspective of the purpose, it is applied; and as for data collection, it is a survey. The required data were collected through a questionnaire validated by experts, from academia and from Bosch Car Multimedia. The research hypothesis suggests that there is a significant relationship between KM and organisational agility. Therefore, improving KM through agility variables may contribute to higher levels of competitiveness of companies. KM and agility are dependent, and therefore, the indicators of each of them and their meaning have to be recognised and managed. This study suggests that KM capabilities enable organisations to develop organisational agility, which improves performance.

Published: July 2024

Abstract
In this article, a Modified Sprott C system is considered. The stability of equilibrium points and the occurrence of Hopf bifurcation in the system are investigated. It has been proved that the system displays a Hopf bifurcation at α = 0. Additionally, by applying normal form theory, the stability, direction and increase (or decrease) of the period of bifurcating periodic solutions of the system are illustrated. It has been shown that the solutions of bifurcating periodic solutions at the bifurcation value α = 0 are unstable. The type of Hopf bifurcation is subcritical and the periods of the bifurcating periodic solutions increase.
