Biosilicate glasses and glass-ceramic materials obtained on their basis are an important research area in tissue engineering due to their ability to regenerate bones. The most important features of bioactive glasses include: the ability to biodegrade and high bioactivity. Appropriate porosity, pore size, surface structure and topography, chemical composition and ion release kinetics, as well as mechanical...
Carrying out professional work is inextricably linked to the risk of accidents while performing tasks at the workplace. Accidents at work involve a number of obligations on the part of the employer. One of the legally prescribed actions taken by employers is the need to indicate the cause or causes that led to the accident at work. Due to the implementation of social benefits and possible issues of...
Natural disasters affect not only humans but also all living beings and societal elements. The term "disaster “meaning a Great Calamity. Among these calamities, earthquakes stand out as the most significant in terms of the damages they cause. Internationally, all authorities define earthquakes as the disasters that result in the highest loss of life and property. This paper highlights the urgent...
This work systematizes the knowledge on several food labelling systems, namely the Nutri-Score, the NutrInform, and the Mediterranean Index (Med Index). The Nutri-Score system assesses nutritional value of a product per 100 g or 100 ml with no consideration of usually consumed serving as well as vitamins, minerals, and bioactive compounds. The concept of NutrInform does not label food products as...
The manuscript describes the problem of boiling heat flux determination with the focus on nucleate boiling mode. It presents the boiling phenomenon on the bare surface and provides a review of the correlations that can be used for modelling purposes. Two most commonly applied correlations were validated against the experimental results. One of them showed significant discrepancies, which might be...
The article provides a detailed case study illustrating the practical application of BOST surveys while focusing on the third principle of Toyota. This particular principle underscores the importance of achieving an even distribution in production to mitigate fluctuations and ensure the smooth functioning of the production process. The article delves into a comprehensive analysis of how this principle...
This study delves into the critical process of risk management within manufacturing environments, emphasizing its role as a perpetual cycle influencing all organizational tiers. The research primarily addresses the identification, analysis, and mitigation of risks in specific occupational roles within a manufacturing company. A comprehensive risk assessment is conducted for these roles both pre and...
Adapting city space to the needs of disabled people is an increasingly important area of activities of local government authorities. Well-thought-out architecture of buildings, road construction and adaptation of broadly understood urban transport ensure free use of city life for all users. The aim of this study is to analyze chosen urban planning solutions tailored to the needs of disabled people...
Due to the increase in gas emissions and the growth of environmental problems globally, companies are striving to reduce their emissions and waste products in order to become more sustainable and preserve the environment. In order to solve this problem, an initiative called Science Based Targets has been created with the aim of defining targets and paths for companies to follow in order to reduce...
The most common types of damage in distribution networks with a voltage of 6-35 kV have been analyzed. It is shown that the majority of them are single-phase circuits, which can cause overvoltages at the point of damage and negatively affect electrical equipment, which can lead to a decrease in economic indicators. The methods of increasing the reliability of distribution networks with a voltage of...
The article presents the optimization of supply chain management in a foundry using computer simulation with the FlexSim program. The authors analyze collaboration with external entities in the production process, focusing on the settlement of raw materials, transportation services, and storage costs. Special attention is given to the production plans of subcontractors integrated into the operational...
The paper deals with the assessment of the current state of financial management of small and medium-sized enterprises in the conditions of the market economy in Slovakia and points out that during the transformation for the sake of sustainability, financial managers must find answers to many and com-plex questions related to sustainability and financial performance of the enterprise. It is therefore...
This article analyzes the results of social research on the determinants of decision-making in the field of running a business – especially the innovative one. The research was conducted on a sample of 400 inhabitants of the Silesian Voivodeship (Poland). The region of the Silesian Voivodeship is, in this respect, a specific region in Poland - highly urbanized, industrialized with a rich communication...
In the world market, success is achieved by the countries that have better human capital and allocate sufficient resources for its reproduction. One of the results of the growing enrollment of many universities has been the need for additional qualified teaching staff and advanced training, which has led to the need to retrain existing teachers for staffing the growing number of higher education institutions...
The rapid and voluminous development of renewable generation, and its stochastic nature, creates problems in terms of maintaining frequency and balance in the power system. In this work, demand response management and the use of the concept of demand response are discussed in detail. The potential of using prosumers to maintain the power balance in the power system is considered. The analysis of prosumers...
This article explores the multifaceted issues of occupational hazards in agriculture, focusing on common causes, circumstances of accidents, and preventive measures. Agriculture is recognized as one of the most hazardous industries, second only to construction. The study delves into the reasons for the high incidence of accidents, which include a tolerance for risky behaviors, poor engagement, lack...
The variability of hazards occurring during the construction and expansion of temporary metal structures is the result of many factors. It mainly depends on the environment in which the structure is to be built and the ground on which it is to be located. The fitter generates the most threats during work related to the transfer of elements of a given metal structure as well as assembly and disassembly,...
Laser surface texturing (LST) has emerged as a versatile and efficient technique for modifying surface properties across various materials. This paper provides an analysis of the characteristics and diverse applications of laser surface texturing. The paper begins by explaining the fundamental principles underlying LST, highlighting the mechanisms involved in material interaction and the resultant...
The article explores how qualitative image analysis impacts the process of image interpretation, particularly in composite microstructure analysis. It highlights the importance of high-quality images for accurate computer-based object detection, emphasizing the limitations of rigid pixel-based rules compared to human visual perception. The study underscores the need for optimal imaging conditions...
The article presents an overview of research conducted on the development of camouflage coating systems in the range of ultraviolet, visible, near infrared and radar waves, as well as operational tests of these systems. Among other things, the influence of temperature on coating systems and tests in chambers with cyclically changing conditions is presented.
