Abstract The aim of this work was to study the content of biologically active compounds in aqueous and ethanol extracts of the roots and rhizomes of elecampane, meadow clover grass and sea buckthorn berries, as well as to determine the indicators of their antioxidant activity. Water extracts were prepared in the form of two dosage […]
Abstract The study is devoted to the urgent problem of finding effective means of forming the learning motivation of students who are future teachers. The quality of education is largely determined by the level of formation of learning motivation. In the conditions of the innovative nature of modern education, the search for effective pedagogical tools […]
Abstract Blockchain is currently considered as a key technology that can significantly reduce the level of transaction costs in the economy, reduce the level of economic and financial risks, and increase the efficiency of economy and financial sector. In this regard, it is relevant to study the possible trajectories of blockchain transformation under conditions when […]
Abstract Plain bearings limit the performance of the crankshaft of an internal combustion engine (ICE) to major repairs. Their reliability is determined by heat resistance, wear-resistance and endurance limits of the materials of which the bearing is made. Dynamic loads reduce bearing life. Plain bearings, heavy-loaded and operating at a high rotational speed of the […]
The main reason for reducing the life of the failed engines in operation is the cranking of the connecting rod inserts. Crankshaft bearings operate under constantly changing loads and speeds, as well as with varying amounts, pressure, temperature and viscosity of the oil supplied to them, which ultimately leads to increased wear on the […]
Abstract With the development of industry, there are higher requirements for the quality of process water, as well as the composition of industrial wastewater. To meet the quality requirements, water is increasingly used in membrane methods or a combination of methods with membrane purification methods. Therefore, at present, the actual issue is the development of […]
Abstract The article presents the approaches and interpretations of virtual reality of various authors, reveals the features of concept interpretation. The features of virtual reality associated with relevance, interactivity, autonomy, immateriality, ephemerality are given. According to J. Baudrillard, the virtual reality simulacra fill the social space, contribute to overproduction of meanings, alienation of human, blurring […]
Abstract The contribution made by authors in a calculation of a cube of a number includes the digital architectures leading to a computation of cube of an 8- bit binary number which produces the result with reduced hardware utilization on FPGA. The cube is a prominent operation required in many mathematical operations, signal and digital […]
Abstract The advanced bit processing operations implemented in the microprocessors and microcontrollers very inefficient. Normally programming techniques are used to emulate the complex bit-related operations. The bit manipulation functions are every now and then required in the areas that are eventually becoming very important. This paper is proposing a techniques which can directly support these […]
Abstract Due to the active development of information technology, information is of great value to date. Any sphere of public life can be described by information, loss or modernization of which can lead to large losses. Thus, information becomes strategic resource of the state and business of all levels that are interested in its preservation. […]
