Comprehensive use of 6G cellular technology accounting activity costs and cyber security
The purpose of this study was in the research of prospects for simultaneous use of 6G generation cellular communications for the purposes of automatization of cost accounting of the activity of enterprises of various branches and cybersecurity of accounting information. The theoretical and methodological aspects of the use of 6G cellular network technologies for accounting and cybersecurity purposes have been studied on the basis of general research methods – institutional and innovative; economic and mathematical methods of analysis using Excel spreadsheets were used to predict the pace of implementation of cellular communication of new generations; to determine perspective areas of use of 6G technology – methods of bibliographic and comparative analysis using the information resource "ResearchGate". The methods of permanent collection and transmission of accounting data about the production process and the procedure for monitoring the stay of employees or outsiders at the workplace using production equipment connected to the 6G cellular network has been developed. The procedure for combining the functional abilities of Global Positioning System (GPS) and cellular positioning (mobile subscribers) for accounting of transport costs and control over the movement and economic use of vehicles has been proposed.The procedure for combining unmanned aerial vehicles in a cluster on the basis of 6G communication with the purpose of aerovisual surveillance of agricultural and construction activities for automated accounting of production costs and prevention of unauthorized getting into an enterprise of persons (drones). The methods for determining the cost of rental space from the lessor based on counting the popularity among visitors and identifying offenders (thieves of information and material resources) through automated monitoring of the location of 6G cellular subscribers. The practical implementation of the developments presented in the article on the use of 6G cellular technologies will contribute to reliable costing and accounting of production costs of production, agricultural, construction, trade activities in combination with effective cyber protection of enterprises in preventing and detecting violators of information and territorial security.

Specifics of the Surface Structure of Steel Products After Various Laser Alloying Methodics
In modern conditions, volumetric alloying of steels is becoming an increasingly less economically viable process. However, the level of performance properties of unalloyed steels cannot cover the current industry needs. One of the ways to solve this problem – usage of various surface alloying methods of steels, makes it possible to obtain the required properties of the working surface of the alloyed part with minimal consumption of expensive alloying elements. Over the course of the study, combined method of laser-plasma alloying of steel surfaces was analyzed, its technological capabilities were determined, and the structural-phase state of surface layers, formed during laser and hybrid laser-plasma processing was compared. During comparative studies of samples obtained by both methods of surface alloying, it was found that in the case of laser-plasma alloying, the observed structure and carbide phases are smaller in size, with a low density and uniform distribution of dislocations in the metal of the alloyed layer. After various analysis, it was established that during both laser and laser-plasma methods of surface alloying, the crack formation tendencies was mostly attributed to various structural and concentration changes associated with the redistribution of elements, leading to the formation of sharp grain-boundary concentration gradients. An increase in the number of cracks is observed in regimes with higher heating temperatures, increased duration of exposure to high temperatures and reduced cooling rates

Revealing changes in the technical parameters of the teat cup liners of milking machines during testing and production conditions
To implement effective cow milking, it is necessary to take into account the peculiarities of the milk flow process, the milking machine's adaptability to perform the given technological functions.
The aim of research is to establish changes in the design and technological parameters and physical and mechanical properties of teat cup liner of milking machines during its testing and in production conditions. The results obtained will make it possible to make a rational choice of rubber, ensure an efficient milking process during its service life.
It is found that the tensile strength of silicone teat cup liner at the beginning of operation was 1.6 times higher than that of a rubber compound, and after 6 months. operation – 1.7 times. With respect to the relative elongation, this difference was 1.4 times, and after operating time – 1.3 times.
Studies have proven that rubber during operation changes its physical and mechanical properties: the length of the active part increased by 3.1 mm; wall thickness – 0.2 mm. It is found that the most intensively elastic properties of teat cup liner changed during the first 10–20 days. After 10 days, the closing vacuum increased by 16.6 % compared to the initial one, and after 20 days by 23.3 %, which amounted to 8.57 and 9.06 kPa, respectively. Up to 420 hours of operation, the clamping vacuum reached 11.3 kPa, which is 5.8 % lower than the requirements for toughening teat cup liner for rejection. In general, over the period of experiments, the average value of the vacuum of closing the opposite walls of teat cup liner increased from 7.35 to 12.43 kPa, which is 3.6 % higher than the norm (12 kPa).
As a result of experimental studies, the regularity of the rubber tension force depending on the operating time in the form of a fourth degree polynomial is obtained. It is found that after 150 hours of operation, the tensile force of teat cup liner decreased by 21

CERN Tape Archive Run 3 Production Experience CTA Tier-0 service performance during the start of the LHC Run 3 and the various lessons learnt
The EOS disk + CERN Tape Archive (EOSCTA) service is CERN’s primary physics data long-term storage and archival solution for LHC Run 3. It entered production at CERN during summer 2020 and has since been serving all the LHC and non-LHC workflows involving archival to-and retrieval from tape.
The CTA system is a complete redesign of the previous tape software, tape cache and tape workflows, which will need to scale to the data rate requirements of the present LHC activity period, as well as the one after. At the time of writing it has already set new records for monthly tape archival volume at CERN and reached write efficiencies equalling those demonstrated during earlier data challenges
