Authors: Czapran Tomasz 
Published: April 2023

Purpose: is the issue of managing an age-diverse workforce in a company or enterprise.
Method: the article used the method of empirical calculations.
The results of the study: during the research it was established that teams are most productive when they are not made up of the same people, people in the team must be able to work together and respect each other, but at the same time, they should represent different qualities, experiences, and skills that will complement each other for the benefit of the whole team.
Практична цінність дослідження: Cooperation within age-diverse teams increases the value of group or team IQ. It has been empirically proven that the element which most significantly affects group IQ is not the average IQ of individual group members, but rather the level of their emotional intelligence. The key to a high group IQ is harmony in the relationships of group members, communication skills and receptivity.

Results of the first practical application Brolucizumab for the treatment of neovascular age-related macular degeneration
Authors: Kuranova O. I. , Guseva E. V. , Antonuk V. D. 
Published: April 2023

Introduction. Today the standard of treatment neovascular age-related macular degeneration is frequent intravitreal injections of antibodies to vascular endothelial growth factor. Brolucizumab is one of these medicines, which is a single-chain humanized antibody variable fragment with a very small molecular weight (26 kDa). In our country, there are quite a few publications about the results of using Brolucizumab in the Russian Federation due to the fact that this drug began to be used recently (since mid-2021).Purpose: to evaluate our own experience with Brolucizumab treatment of neovascular age-related macular degeneration (nAMD).Materials and methods. The study included 25 patients with nAMD for the period from September 2021 to June 2022, among them 17 women, 8 men, the average age of the patients was 77.07 ± 4.88 years. All patients were divided into 2 groups. The first group included 15 patients previously treated with Ranibizumab. The second group included 10 patients who had not previously received anti-angiogenic therapy. All patients underwent an average of 2 or more IVIs of Brolucizumab and a standard ophthalmological examination, as well as optical coherence tomography (OCT) at the first checkup and one month after each IVI with using the Nidek RS-3000 Advance Angioscan device (Nidek, Japan). All patients included in this study signed an informed consent for it.Results. Almost all patients during the anti-angiogenic therapy with Brolucizumab showed an improvement in anatomical and functional parameters. In the first group the average visual acuity at the time of data analysis increased by 12.7% compared to the baseline, while in the second group - by 57%. The average thickness of the central retina zone in patients of the first group decreased by 13.8% compared to the initial one, while in the second group by 50.9%. During the study period, one case of an adverse event in the form of moderate vitreitis was registered, which occurred on the 8th day after the fourth IVI of Brolucizumab, previously the patient received two IVIs of Ranibizumab. At the time of data analysis, the patient continued to receive anti-inflammatory therapy with positive dynamics in terms of stopping the symptoms of vitreitis.Conclusion. This study showed the high efficacy of Brolucizumab in the treatment of nAMD, which was manifested by an improvement in anatomical and functional parameters in patients of both groups. However, the treatment efficacy was higher in patients without previous antiangiogenic therapy. The resulting case of side effect in the form of intraocular inflammation requires a deeper analysis in order to correctly select patients for IVI in the future.

Published: April 2023

Currently, there is a significant shortage of donor materials for replacing corneal tissue that is why it is relevant to create xenomaterials, which are able to replace a donor cornea with various types of keratoplasty. “Corneoplast” is a new medical device, which is a devitalized, fixed by the method of double crosslinking (dehydrothermic + UV), pork cornea.Purpose: to assess the biocompatibility and ability to integrate with the recipient cornea of implants based on the xenomaterial “Corneoplast”.Materials and methods. The experiment was based on biomicroscopy examination, high-resolution optical coherence tomography and histological examination of the experimental rabbits’ corneas (group I–IV: total of 8 eyes were examined), where keratoplasty was performed with the “Corneoplast” material.Results. High biocompatibility and ability to integrate with the recipient’s cornea were observed in all types of keratoplasty: penetrating, superficial lamellar and intralamellar keratoplasty. On the next day, the implant was transparent with slight swelling of the recipient’s corneal stroma. A week later, the slight swelling of implant was recorded without cornea edema. Its transparency decreased. The recipient’s cornea was reactive. A month later, the moderate neovascularization was noted towards the sutures. After 6 months, the recipient’s cornea was clear, transparent. The implant was translucent and neovascularization was absent. The entire surface of cornea and implant was epithelialized. On the series of optical coherent tomograms, a normal thickness of the epithelium continuous layer was determined in 6 months after the surgery. The complete integration of material with the recipient’s cornea was noted. The layered structure characteristic of corneal tissue was preserved. The cornea retained a layered structure and the endothelium was preserved. On histological examination, there were no differences in the intact cornea and implanted material.Conclusion. The “Corneoplast” material is sufficiently biocompatible and capable of integration with the recipient’s cornea in an animal experiment. This allows, at a certain stage of preclinical trials completion, to use it for replacing corneal tissue in penetrating keratoplasty, intralamellar and superficial anterior layer-by-layer implantations and to cover purulent corneal ulcers of various depths.

AbstractA simultaneous transfer and bonding (SITRAB) process using areal laser irradiation is introduced for high‐yield and cost‐effective production of mini‐ or micro‐light‐emitting diode (LED) display panels. SITRAB materials are special epoxy‐based solvent‐free pastes. Three types of pot life are studied to obtain a convenient SITRAB process: Room temperature pot life (RPL), stage pot life (SPL), and laser pot life (LPL). In this study, the RPL was found to be 1.2 times the starting viscosity at 25°C, and the SPL was defined as the time the solder can be wetted by the SITRAB paste at given stage temperatures of 80°C, 90°C, and 100°C. The LPL, on the other hand, was referred to as the number of areal laser irradiations for the tiling process for red, green, and blue LEDs at the given stage temperatures. The process windows of SPL and LPL were identified based on their critical time and conversion requirements for good solder wetting. The measured RPL and SPL at the stage temperature of 80°C were 6 days and 8 h, respectively, and the LPL was more than six at these stage temperatures.
Mixture of Carbon-Dioxide and Liquefied Petroleum Gas as Refrigerants in Vapour Compression Refrigeration System: A Review

Published: April 2023

In this paper, the mixture of CO2 and LPG is being investigated, and the salient properties of the refrigerants were the main pointer to the development of a mixed refrigerant. Since CO2 offers a much higher volumetric capacity, the problem of the higher working pressure can be overcome by mixing it with a lower pressure refrigerant. LPG on the other hand has a cooling capacity of about 10% higher than R12 and the vapour pressure is appropriate. It has excellent thermodynamic properties leading to high energy efficiency and operates at lower pressures than other main refrigerants while maintaining a similar volumetric refrigerating effect, but it is highly flammable. Therefore, by combining CO2 and LPG in the right amounts, we can create a blend that will have low pressure while also being less combustible, more effective at cooling than the old one, more energy-efficient, with an improved coefficient of performance (COP), and safer for the environment. The different studies examined demonstrate that combining CO2 and LPG created products with greater refrigerating effect capacity, enhanced coefficients of performance (COP), were more energy-efficient, and were also secure and safe for the environment; that can be used to replace the existing refrigerants.

Tool development and prime mover selection for optimum tillage operation require both the knowledge of soil and tillage tool interaction dynamics which is a function of some system parameters. The actual value of these parameters can only be determined either from field or soil bin experiment via appropriate instrumentation systems. Several published works have been reported on development of soil bin instrumentation system. However, development of a system that can measure and log all the required parameters simultaneously in real time remains an active area of research. The distance moved and the forces acting on the tool were sensed using potentiometer and load cells, respectively. The sensed parameters and the calculated tool linear velocity were processed in parallel using microcontroller with optimised code to ensure real-time and simultaneous logging. The developed system was used for measuring and logging the distance moved by the tool, its velocity as well as the x-, y-, and z- components of force acting on the tool. The values of the distance, velocity and force were determined any time from the start of tillage operation are available on the chats of distance/velocity/force against time obtained from this work. 10 seconds from the start of tillage operation, the distance moved by the tool, tool velocity, , , and are 2.56 m, 0.27 m/s, 147.00 N, 5.00 N, and 15.00 N, respectively.
Validation of Rayleigh-Ritz Deflection Equation for a Tapered Cantilever Beam using ANSYS Finite Element Software
Authors: Ufe Moses M. , Iorliam Amos Y. , Odeh Omojo B. 
Published: April 2023

Models are like our eyes and ears as they provide the basis for making very important design decisions in engineering. They give predictions that help engineers to foretell or foresee a system’s behaviour in real life. Validation ensures that these models give proper or accurate representation of the real system. In this study, a model equation derived for predicting the end deflection of a tapered width, constant height cantilever beam was adopted for validation. This equation was derived using the Finite Element Method's Rayleigh-Ritz principle and the virtual work concept. Using a finite element model developed in ANSYS as the representation of the real system and a basis for validation, this study aimed to validate the equation. Validation was achieved by the comparison of the load-deflection curve, the height-deflection curve and the end deflection of the model equation to that of the finite element model in ANSYS. Though the model equation was verified to really foretell deflection, the predictions of the equation was not in good agreement with that of the finite element model. The accuracy of the equation dwindled as the parameters of the tapered cantilever beam were varied. It gave an average percentage error of 30% higher than the allowable error of 5%. Though the equation was derived using the appropriate fundamental numerical principles as it basis, it’s accuracy can be exponentially increased by modifying it to include a larger number of discretized elements and a higher degree of shape/interpolation function.
