Authors: Mysak Stepan , Shapoval Stepan , Hyvliud Anna 
Published: July 2024

The object of the study: a system with a photovoltaic thermal hybrid solar collector.
The main problem addressed is to enhance the conversion and utilization efficiency of solar energy by developing a new design of photovoltaic thermal hybrid solar collector.
A computer model of the proposed design of a photovoltaic thermal hybrid solar collector (PVT) was developed, and its thermotechnical characteristics were investigated. Patterns of temperature changes in the heat transfer fluid in PVT and thermal accumulator over time of irradiation were determined. It is shown that the instantaneous thermal power of the solar collector was 540 W/m2, and the efficiency was 0.6. Changes in the instantaneous specific thermal power of the system with PVT (up to 450 W/m2) and its efficiency in heat accumulation in the accumulator (0.5) were studied. The high efficiency of PVT can be explained by its optimal design, which ensures simultaneous production of thermal and electrical energy, as well as balancing of the operation of the thermal and photovoltaic parts. The main difference between the developed model and existing analogs is the comprehensive consideration of the interaction of the thermal and photovoltaic parts in one installation. The model allows optimizing the PVT design to increase its efficiency. The research has allowed developing a new design of a photovoltaic thermal hybrid solar collector, which ensures high efficiency of conversion and utilization of solar energy.
The obtained results and the developed model provide a basis for further improvement of PVT and its implementation in power systems of buildings and technological processes to increase the share of solar energy utilization and reduce fossil fuel consumption

The object of this study is the process of planning the work of a manufacturing enterprise that needs transport and forwarding services when exporting goods to counterparties in different countries of the world.
The problem being solved is predetermined by the need to devise recommendations for choosing a transport and forwarding company when serving an individual customer, based on its individual needs and conditions of cooperation.
A simulation model for the selection of a transport and forwarding company was constructed and implemented to meet the customer’s needs when exporting goods, applying the GPSS World simulation automation package.
The model provides for the optimization of the choice of a transport and forwarding company for servicing counterparties based on the assessment of their activity indicators over previous periods of cooperation.
When building the model, the types of commercial conditions of the exporter’s cooperation with the transport and forwarding company, indicators of the quality assessment of the basic level of service and the duration of service at all stages of the foreign trade operation were taken into account. The application of the constructed model in practice will enable exporters and importers to choose a transport and forwarding company depending on the individual needs of customers in the delivery of goods. The simulation results reflect the performance indicators of the provision of transport and forwarding services by various specialized enterprises. This will make it possible to involve in the transport and forwarding service of a separate counterparty an organization that will meet all the requirements of goods buyer in accordance with the terms of the international economic contract. At the same time, the duration of choosing and agreeing the terms of cooperation could be reduced by 12–15 % while the efficiency of transport and forwarding services would increase by 13–16 %
Determining performance characteristics of jet water-gas ejectors for an opening in a vertical fencing structure
Authors: Hrynchak Serhii 
Published: July 2024

The object of this study is jet water-gas ejectors (JWGEs) in the system for ensuring fire safety of ships. The problem that was solved: in the event of a fire, in the shortest possible time, a high temperature rises in the area of ​​the exit from the ship's emergency room and a large amount of smoke spreads throughout the ship's premises. These factors require immediate sealing of the emergency room, which limits the immediate access of emergency teams to the interior. Installation of a local air support system based on JWGE in the doorway could make it possible to shield thermal energy and localize smoke gases in the emergency room without sealing it to ensure prompt access of emergency teams. The main results that were achieved relate to the adequacy of theoretical studies on the processes of localization of flue gases in the emergency room without its sealing confirmed by the experimental method. The investigated problem was solved by optimizing processes: the intensity of smoke emission from the working characteristics of jet water-gas ejectors; the rate of change of the natural indicator of the weakening of the environment at the start of JWGE system; speed of reaching the required temperature from the time in the adjacent room. Special feature of the results was the formation of an air curtain, obtained by the selection of a part of high-temperature flue gases into the JWGE housing, their heat and mass exchange treatment and output back into the flow. This created conditions under which thermal energy shielding occurs with a fairly high efficiency of 85–88 %. And it was also established that the decrease in the intensity of gas exchange through the open hole, in which the JWGE works, occurs already at the 0.3 MPa regime in the fire pipeline. The scope and conditions of practical use of the reported results are shipbuilding and ship fire safety design
Revealing the influence of wind vortex shedding on the stressed-strained state of steel tower structures with solid cross-section
Authors: Nuzhnyj Valerii , Bilyk Serhiy 
Published: July 2024

This work investigated the effect of vortex shedding during the action of wind on tower structures with a solid cross-section. Failure to take into account this influence, together with the manifestation of the phenomena of physical wear of structures during long-term operation, can lead to building accidents. The object of the research are tower structures with a solid cross-section, which are widely used in modern infrastructure ‒ advertising pylons with a transparent advertising structure with a height of about 12, 22, 25 m, and a flagpole with a height of 48 m. The most frequent manifestations of oscillations according to the first natural frequency and shape have been considered, which occur even with moderate winds and when a large number of oscillation cycles occur. In this work, the number of oscillating cycles per year was determined and estimated based on the archive of meteorological observations. It was found that the number of oscillating cycles due to the action of wind excitation for the example of the structures under study is from 2.6 to 14.4 million per year, which requires the mandatory limitation of stresses in the parts of structures during the design to enable their durability. The magnitude of forces from vortex shedding for the studied structures ranges from 2.9 to 43.5 % of the forces caused by the influence of the frontal wind, depending on the height of the structure. Thus, it was found that the influence of vortex shedding is very insignificant for structures up to 12–15 m high and increases for structures 20 m and higher. Rational forms of the cross-sections of structures were established to reduce the influence of vortex shedding ‒ these are cross-sections of a circular and a cross-section close to it. In a general formulation, these are sections for which peak stresses relative to forces in one plane fall into the neutral zone for stresses from forces in another plane. Recommendations have been also given on the simultaneous consideration of forces from the action of frontal wind on the structure and vortex shedding since both manifestations of wind action on tower structures cannot be separated

Published: July 2024

The object of this study is the process of filtering astronomical frames that contain images of potential objects in the Solar System. To contour the image of each such object and recognize it in contrast with the background of the frame, it is necessary to filter the image. Most often, a variety of high-pass filters are used to determine the high-frequency component of the image, which can be removed as a coarse-grained component. Any image filtering is aimed at increasing the signal-to-noise ratio and reducing the dynamic range of the background image. However, the filtering process is quite resource- and time-consuming. This is especially true for systems for parallel processing of series of astronomical frames in real time (online). Therefore, to solve the problem of lack of frame fragmentation, which leads to high consumption of RAM, a procedure for fragmenting astronomical frames has been proposed.
Owing to the introduction of a formal connection between the values of frame pixels and fragments, as well as determining their number, it was possible to reduce RAM utilization. Testing was carried out using the following high-pass filters ‒ ideal filter, Butterworth filter, and Gaussian filter. Using the devised procedure for fragmenting astronomical frames has made it possible to reduce the utilization of RAM during filtering. As a result, with parallel processing, this has also made it possible to speed up the high-frequency filtering procedure itself.
The procedure devised for fragmenting astronomical frames was tested in practice within the framework of the CoLiTec project. It was implemented in the On-Line Data Analysis System (OLDAS) of the Lemur software.
The study showed that when using the devised procedure, RAM utilization was reduced by 7–10 times. And the speed of filtration itself increased by 2–3 times. Accordingly, the processing time for each astronomical frame was reduced by 2–3 times

Published: July 2024

The object of this study is the process of electron beam 3D printing of articles made of TA15 titanium alloy powder. Peculiarities of the structure and properties formation of alloy blanks, obtained by this method have been described. Influence of process parameters (electron beam power and geometric scanning parameters) on the characteristics of the material were considered.
Step of displacement of the beam trajectory changed from 0.1 to 0.25 mm with an interval of 0.05 mm. Specific energy of the electron beam varied from 20 to 70 J/mm3 for every trajectory displacement step.
The macrostructure was examined visually while the microstructure was studied by optical microscopy. Mechanical properties were determined by uniaxial tension and impact bending tests. It was established that depending on the 3D printing parameters the macrostructure of most samples is dense but with unfavorable parameters non-fusions or shrinkage porosity defects may form. The microstructure of the dendritic type has an α´+β lamellar-acicular morphology, its dispersity and shape of α´–phase areas vary depending on the process parameters.
A scanning step of 0.2 mm and a beam energy of 40 J/mm3 allows obtaining a dispersed microstructure in which there are no non-fusions and shrinkage micropores. The value of the Rm is 27 %, and the R0.2 is 24 % higher than that of the alloy obtained by the conventional technology of electron beam melting. The A5 is 3.2 times higher. However, impact toughness of the sample with dendrite unfavorable orientation to the direction of load applying may be lower compared to conventional technology. The results could be used for devising commercial technology of high strength titanium alloys parts produced by 3D printing

Aim. To investigate the methods of early diagnosis of oxaliplatin-induced peripheral neuropathy (PN).Materials and methods. The study included 52 patients with diagnosis of metastatic colorectal cancer receiving 1st line polychemotherapy per the mFOLFOX6 scheme ± targeted therapy who prior to each cycle filled out the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy (EORTC QLQ CIPN 20) and were subject to neurological examination using the Neuropathy Disability Scale (NDS).Results. The analysis included 28 patients who completed polychemotherapy: 16 (57,2 %) men and 12 (42,8 %) women, mean age 60.0 ± 10.0 years. Fridman’s two-way analysis of variance by ranks showed significant changes in the scores (sensory, motor, autonomic) of the EORTC QLQ CIPN 20 questionnaire with the increase in the number of chemotherapy cycles (р = 0.001). Significant increase in the sensory and motor scores was observed after the 3rd cycle, in the autonomic – after the 6th cycle. Significant increase in NDS score was observed starting at the 3rd cycle, and vibration sensitivity on the medial ankle or at the base of the 1st toe significantly decreased after the 1stcycle. Median number of cycles at which oxaliplatin dose was reduced or the drug was discontinued due to clinically significant symptoms of PN irrespective of questionnaire results and neurological examination was 6.Conclusion. According to the results of the study, the following conclusions were made: 1) sensory scale of the 3-part EORTC QLQ CIPN 20 questionnaire (9 questions of 20) or motor scale (7 questions of 20), vibration sensitivity can be considered as stand-alone informative tests; 2) in a large patient cohort, NDS score increase to 5, EORTC QLQ CIPN 20 sensory scale score increase to 12 and higher or decreased vibration sensitivity on the medial ankle or at the base of the 1st toe to 4.5 arbitrary units should be considered early manifestations of PN; 3) for a routine algorithm, it is acceptable to consider a combination of 9 questions of the sensory or 7 questions of the motor scales of the EORTC QLQ CIPN 20 questionnaire and evaluation of vibration sensitivity on the medial ankle or at the base of the 1st toe to decide on oxaliplatin dose reduction or measures for prevention of peripheral neuropathy symptom worsening.

Published: July 2024

In sum, the adoption of the Bhartiya Nyaya Sanhita, Bhartiya Nagrik Suraksha Sanhita, and Bhatiya Sakshya Adhiniyam signifies a transformative milestone in post-independence India's legal evolution. By embracing indigenous wisdom, democratic values, and global insights, these legislations aspire to catalyze a more equitable, efficient, and accountable legal system, poised to meet the complex challenges of the 21st century. As forensic medicine continues to play an increasingly pivotal role in the Indian justice system, practitioners must remain abreast of these legal developments and uphold the highest standards of professionalism and integrity in their work.The Indian legal system enacted in colonial era such as the Indian Penal Code of 1860, the Criminal Procedure Code of 1973, and the Indian Evidence Act of 1872 have long been under scrutiny for its relevance and adaptability to contemporary societal needs. In a historic move, the Indian Government has passed a comprehensive framework, replacing these older laws with the Bhartiya Nyaya Sanhita (BNS), Bhartiya Nagrik Suraksha Sanhita (BNSS), and Bhatiya Sakshya Adhiniyam (BSA) effective from 1 July 2024, following Presidential approval on 25 December 2023. The Bhartiya Nyaya Sanhita seeks to revolutionize criminal laws by introducing modern principles of justice, equity, and efficiency. Complementing the Bhartiya Nyaya Sanhita, the Bhartiya Nagrik Suraksha Sanhita addresses the evolving challenges of national security and public safety. Furthermore, the Bhatiya Sakshya Adhiniyam introduces groundbreaking reforms in the law of evidence, reflecting a paradigm shift towards transparency, objectivity, and inclusivity.

Polish Adaptation and Validation of the Penn State Worry Questionnaire for Children (PSWQ-C): Factor Structure, Reliability and Validity
Authors: Talik Elżbieta 
Published: July 2024

This study presents the Polish version of the Penn State Worry Questionnaire for Children (PSWQ-C). The validation of the PSWQ-C in Poland was conducted through two studies. Study 1 examined the initial factor structure, internal consistency, and construct validity of the PSWQ-C in two samples of school students (N = 819) aged 8–19 years (M = 14.63, SD = 3.09). Study 2 involved 620 participants aged 8–19 years (M = 14.35, SD = 3.42). We conducted Confirmatory Factor Analysis to compare the initial factor structure with different models mentioned in the literature. The results suggest that the scale has good psychometric properties, including good reliability and acceptable validity. The factor structure that showed the best fit to the data consisted of one general worry factor and two method factors representing wording effects. This study is part of a broader discussion on the factor structure of the PSWQ-C. The results suggest that the questionnaire is homogeneous and measures one latent variable, worry, despite a bifactorial model being the best fit for the data. The two sub-factors do not have any psychological meaning (“non-worrying”), but are only an effect related to the positive or negative wording of the scale’s statements.
