The scope of the findings is constrained to the geographic context of Saudi Arabia, inviting future investigations in a broader international context.

The article assesses the structural strength of sample materials destroyed on standard equipment for determining the mechanical properties of materials. The distribution of mechanical stresses of laboratory disk samples with stress concentrators in the form of grooves on the support surfaces was analyzed. It was revealed that the disc truncation along the two symmetrical chords allows for varying the type of stress state in the sample and intensity of stresses in the working zone. The problems of the linear theory of elasticity were solved for samples with different degrees of disc truncation and with different geometric parameters of the groove profile. The analysis of disk deformation showed that these laboratory samples can be used in simulating the type and level of stress-strain state of various parts of machines and mechanisms. This factor significantly expands the possibilities for assessing the structural strength of materials during laboratory studies of the materials. It was revealed that the type of stress-strain state (SSS) plays a role in localizing the sources of destruction of highly loaded structural elements made from structural carbon steel St45. The results can be used both for the experimental assessment of the structural strength of materials and for constructing limit state equations corresponding to a SSS level and type.

Retail food businesses are important contributors to the economic stability of nations, contributing to the economy in different ways, including providing jobs in the supply chain pipeline. Global events like the pandemic arising from the spread of COVID-19 threatened the aptitude of retail food outlets to operate due to the restrictions put in place to mitigate the spread of the virus. The objective of this research is to investigate the determinants that impact the longevity of organizations in the food retail industry and construct a survival model that accounts for these characteristics considering the COVID-19 pandemic, and examining the roles of variables such as organizational survival, external general environment, corporate governance policy, transformational change management, economic condition, and marketing innovation. The study utilized quantitative methodology, employing a survey questionnaire to gather data from a sample of 360 entrepreneurs. Subsequently, the data was analyzed using statistical analysis and the Structural Equation Model (SEM). The research findings reveal that the external general environment, transformational change management, economic conditions, corporate governance policies, and marketing innovation have statistically significant positive impacts on organizational survival. Consequently, food retail businesses must adapt within the COVID-19 context, under evolving external conditions, to strategize for enhanced competitive capabilities. This includes managing change and economic conditions for survival in a COVID-19 pandemic characterized by rapid economic shifts, human behavioral changes, and adaptive governance policies that align with situations. These findings can be applied to organizational structures, addressing weaknesses and further enhancing organizational strengths to create innovative marketing approaches that align appropriately with current circumstances for organizational survival. An important limitation of the study is that data were collected from only 360 food retailers in Thailand, representing a partial population of the food retail business in Thailand, hence limiting the generalizability of the results beyond the context of the study and other countries.

In this article, mathematical modelling of torsional vibrations of a truncated circular conical shell located in an elastic medium is carried out. It is believed that the shell is exposed to external dynamic loads, and its material is homogeneous and isotropic. Based on the exact mathematical formulation of the problem, general equations of nonstationary torsional vibrations of a truncated conical shells have been developed, from which, in particular cases, the equations of vibration of a truncated conical rod, as well as a circular cylindrical shell and a round rod follow. The desired functions found by solving the vibrational equations are used to construct a method for computing the stress-strain state of any point in the system under investigation. As an example.

Financial performance is an evaluation of a company's assets, liabilities, equity, expenses, revenues, and profitability. This evaluation provides an overview of the company's overall financial health during a certain period. Resource Based Theory states several factors that can affect financial performance, namely intellectual capital and competitive advantage. This research was conducted with a quantitative approach. The observed population of this research is all BPRs in Bali Province which are still operating in 2017 - 2021. Determination of the sample in this study using the census method or saturated sample so that the sample used in this study was 133 BPRs in Bali Province. The analysis technique used in this research is path analysis with Eviews version 9.0 software. The test results show that intellectual capital has no effect on financial performance, intellectual capital has a positive effect on competitive advantage, competitive advantage has a positive effect on financial performance and competitive advantage is able to mediate the effect of intellectual capital on financial performance. The results of this study are expected to contribute to various interested parties, namely the development of Resource Based Theory as a theoretical benefit and BPR management, government, OJK, society and the banking industry as practical beneficiaries.

This study investigates the generalized stiffness of laterally functionally graded materials (LFGMs) and applies these findings to dynamic beam elements. The generalized stiffnesses of LFGM, coupled with material and cross-sectional properties such as flexural and axial rigidity, mass per unit length, and mass-moment of inertia, are explicitly formulated. In the context of LFGM, material properties depend on an asymmetrical power law function with respect to cross-sectional depth. An example of the generalized numerical stiffness of a circular cross-section is provided for various material properties. To illustrate the application of generalized stiffness to dynamic beam elements, free vibration of LFGM beams with rotary inertia is considered. The dimensionless differential equation governing the free vibration of such beams is derived and numerically solved to obtain natural frequencies and corresponding mode shapes. Numerical results demonstrate a good consistency with the finite element method.

The research aims to investigate how strategic entrepreneurship through innovative effectiveness is used to create value within firms.
