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 %

The object of this study is the implementation of low-temperature processes for the production of meat and vegetable products under the conditions of adding a dried semi-finished product of a high degree of readiness to the recipe when using the designed universal rotary device of continuous action. The rotary device of continuous action for low-temperature processing of meat and vegetable products with a cylindrical working chamber is heated by a film-like resistive electronic heater of the radiating type. It has a stationary wall (with a technical door for unloading and loading the device) and a technical wall (with an opening angle of 90°). On the inner surfaces of the walls, inclined converging ribs with an angle of 25° are installed, which are covered with an electric heater. Semi-finished meat and vegetable products are loaded onto carts with technological containers and mounted on a frameless drum (rotation frequency 0.03...0.06 s–1). The device converts secondary thermal energy into low-voltage power supply voltage (~3...8 W) for autonomous operation of fans.
The proposed integrated adaptive mechanism for the system of complex interaction of the agricultural, processing, and production sectors implies the formation of resource efficiency of production processes from "farm to table". The designed device implements the process of frying meat-vegetable bread under conditions of reaching 80 °C in the center of the product. The obtained temperature field data confirm the uniformity of the temperature field during frying of the product (cooking readiness of the product at the initial weight of 650±20 g – 4.0 hours). The introduction of a multicomponent dried fraction based on potatoes, Jerusalem artichokes, zucchini, and carrots into the recipe of meat-vegetable bread reduces the weight loss of the semi-finished product during frying by 12.3 %. It increases the content of calcium, phosphorus, vitamin C accompanied with a decrease in energy value by 28.1 %

Published: July 2024

Tank facilities storing various combustible substances are a potential source of danger for the environment and human life. Fires in tanks can occur for various reasons: technical malfunctions, human factors, military operations, natural phenomena. One of the effective methods for extinguishing such fires is "sublayer" extinguishing with the help of foam of low multiplicity. The possibility of "sub-layer" extinguishing with the help of compression foam, which has unique properties, has been considered. The object of this study is the processes of stopping combustion during fire extinguishing in steel tanks for the storage of petroleum products with the use of foaming agents of increased stability, which ensure the generation of compression foam in a "sub-layer" way. A mathematical model of the movement of a submerged non-free jet of foam in the medium of motor fuel is given, which adequately describes the real physical processes that occur during "sublayer" quenching of vertical steel tanks. According to the research, it was established that the use of foam with a multiplicity of 10 (K10) is 1.56 times more effective in serving time than the use of foam with a multiplicity of 5 (K5). From an economic point of view, K10 foam also has greater advantages as the costs of the foaming agent during its generation are 3.1 times lower than when using K5 foam. The simulations demonstrated that the foaming agent consumption of the K10 foam is lower than the foaming agent consumption of the K5 foam and results in a different amount of foam coming to the surface. The simulations also showed that the volume of K5 foam increases proportionally with the feeding time, while the volume of K10 foam increases disproportionally and starts to decrease after half the time. The results from the implementation of the mathematical model were fully consistent with the results from experimental studies on extinguishing a model fire of class B
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

Published: July 2024

This research has a research object, namely relational learning with a mathematical modeling approach from graph queries for exploring future topics and user relationships. The problem in this research is the large and varied number of tweets that are produced every day, where each use of hashtags always increases, which has an impact on the accumulation of data that needs to be processed to obtain information because users on social media X can interact to influence trends so as to solve the problem. This requires the application of relational learning by utilizing graph query mathematical models. The results obtained from this research are in the form of a model that can produce predictions of future topics and see user relationships based on interactions on social media with relationships between entities at interconnected nodes. In applying relational learning with mathematical models utilizing graph queries there will be a process of examining the relationships between entities, content and communication interactions in accordance with the definitions and theorems that have been described to observe each node. In relational learning, there will be each node according to the entity used, then the mathematical model with graph queries will connect all the entities to form a graph that can be used as a model for predicting future topics and relationships between users. This research is research with a level of novelty in applying graphical queries to mathematical models to predict future topics and applying relational learning to user relationships so that it can add information related to future communication. Graph queries aim to model a node between relations in the data so that it can represent a relationship between variables

Published: July 2024

The development of new diuretics of plant origin is an actual direction. Chimaphila umbellata (L.) is a perennial herb with diuretic, astringent, analgesic and other effects; and it can treat various conditions such as edema, dropsy, etc. Pipsissewa herb helps the removal of nitrogenous and chloride salts from the body due to the content of arbutin glycoside, tannins (up to 5 %).
The aim. Evaluation of the effect of pipsissewa extract on L929 cell culture.
Materials and methods. Cell line L929 (fibroblasts of mouse adipose tissue) was obtained in the low-temperature bank of the Institute of Problems of Cryobiology and Cryomedicine of the National Academy of Sciences of Ukraine. Cells were cultured in DMEM medium (Bio West, France) enriched with 10 % FBS (Lonza, Germany) with 1 % antibiotic-antimycotic (Bio West, France), in a CO2 incubator (Thermo Fisher Scientific, USA) at 37 ºC in an atmosphere with 5 % CO2.
Determination of the minimum toxic concentration at which the cells remained alive was evaluated by morphological features (shape, monolayer integrity, adhesion to plastic). The study of the effect of pipsissewa extract on various cell functions was determined by the following methods: the ability to preserve morphological integrity - by the phase-contrast microscopy method, energy exchange - by the MTT test method, pinocytotic function - by the neutral red absorption method, migratory function - by the scratch test method, proliferative activity - by the doubling calculation method population
Results. It is proposed to use concentrations of 0.05, 0.02, 0.01, 0.005 % of pipsissewa extract for further research. After carrying out the MTT reaction, the transition of MTT to formazan was confirmed microscopically in the negative control (native cells), at PE concentrations of 0.01 % and below, and the absence of a reaction in the positive control (cells killed by ethanol) at PE concentrations above 0.02 %. When recording the parameters of the NP absorption reaction, it was determined that PE at a concentration of 0.02 % and higher sharply suppresses pinocytotic activity, despite the partial preservation of cell adhesion, reducing the concentration by two times no longer affects mitochondria. A concentration of 0.01 % reduces proliferative activity, and at a concentration of 0.005 %, no difference with the control values ​​was found.
Conclusions. When studying the assessment of the effect of pipsisewa extract on L929 cell culture, a toxic effect on these cells was established when added to the culture medium at a concentration above 0.01 %. The toxic effect had a threshold effect. Migratory and proliferative functions were the most sensitive, energy, pinocytosis and preservation of morphological integrity of cells were less sensitive

The mental health recovery movement recognises the importance of expertise by experience held by service users alongside healthcare practitioners. Recovery has gained attention in music therapy but a situation prevails where practitioners and researchers set research agendas. A group of music therapists recognised the absence of service user voices in music therapy research, and in 2017 they established a network called the Alliance for Recovery Research in Music Therapy (ARRIMT). In 2020, they started to develop a multi-national platform to explore mental health recovery in relation to research. Service users and music therapists were invited from three countries including Ireland, Norway, and the United Kingdom (UK). Local meetings were held to introduce stakeholders from each country, followed by three online meetings. Music was central to each meeting and each built upon content from previous meetings. Our conversations opened up new possibilities for working together. Four priorities for practice and research were identified: Music as a connector; music between sessions; music technology; and, online music therapy. This report will share our process and what we learnt from working together. We contextualise our work within concepts of foregrounding and mattering and view this work as a crucial step towards meaningful co-production. We reflect upon the role of music in building group identity alongside the importance of careful curation. Finally, we present ideas for future music therapy and mental health research.
Group DescriptionIn 2018 the Alliance for Recovery Research in Music Therapy (ARRIMT) was founded as an international group of music therapy service users, researchers and practitioners from Australia, Ireland, Norway, and the United Kingdom. Fundamental to this group is the concept of recovery where those who use and those who provide mental health services work together to share knowledge and experiences that can have a positive impact on mental health service delivery. Key to this is listening carefully to the voices of those who use music therapy so that their views and experiences influence how music therapy is offered in mental health services. The founders and coordinators of the group are Tríona McCaffrey, Hans Petter Paulen Solli, and Catherine E. Carr. Other members of the group are Cornelia Bent, Darmuid Boyle, Oda Bjørke Dypvik, Kenneth Dybdahl, Tommy Hayes, Lauren M. Hickling, Jane Fernandez, Anne Malerbakken, Brendan Ruddy, and Torgrim Vågan.

Mixed endometrial carcinomas (MECs) account for approximately 3%–10% of all endometrial carcinomas (ECs). These are defined as a combination of two or more distinct histologic subtypes, with at least one being a type II tumor that constitutes at least 5% of the overall tumor. However, the associated prognostic factors and treatment of MECs remain unclear. The study aimed to identify theindependent prognostic factors of MEC patients treated with hysterectomy and to explore the optimal treatment modalities for overall survival (OS) and cancer-specific survival (CSS). Using the Surveillance, Epidemiology, and End Results (SEER) database, a total of 12,848 MEC patients treated with hysterectomy were screened. Independent prognostic factors were identified by Cox regression analysis and used to construct the nomogram. The concordance indices (C-indices) of OS and CSS were 0.807 and 0.834 in the training set. Validation of the nomogram revealed that the receiver operating curve (ROC) maintained good discrimination, the decision curve analysis (DCA) had a high net benefit rate, and the calibration curves showed high consistency. Patients were grouped by the nomogram formula and the number of positive regional lymph nodes (NPR-Lymph node) to evaluate the therapeutic outcomes of chemotherapy, radiotherapy, neoadjuvant treatment, and lymph node operation. Survival analysis revealed that chemotherapy could improve the prognosis for OS and CSS in the high-risk group and in the group with NPR-Lymph node counts above 1 (P < 0.05). Radiotherapy was associated with better OS and CSS in the intermediate-risk and high-risk groups, and in the group with NPR-Lymph node counts above 0 (P < 0.05). Lymphadenectomy was found to prolong OS and CSS in the high-risk group (P < 0.05), while neoadjuvant treatment did not prolong OS and CSS in any group. Thus, in this study, the nomogram for MEC patients treated with hysterectomy was successfully built and validated which could effectively predict the prognosis and identify at-risk population to guide clinical decision making. The NPR-Lymph node was identified as a potentially strong prognostic indicator with good clinical value.

Платформенная занятость — активно развивающийся в мире и в России сегмент нестандартной занятости, который охватывает деятельность физических лиц (платформенных занятых) по личному выполнению работ или оказанию услуг, организуемую с использованием информационных систем (цифровых платформ). Представленный доклад посвящен оценке динамики численности платформенных работников в России в 2022–2024 гг. и изучению того вклада, который вносит платформенная экономика в расширение экономической активности и повышение доходов населения. Авторы анализируют тенденции распространенности платформенной занятости и спроса на такой формат у населения за последние два года, а также выделяют группы населения, для которых платформенная занятость является приоритетной и способствует повышению экономической активности (становится единственным вариантом полного или частичного включения в рынок труда), и исследуют их характеристики. Материалы доклада предназначены для широкого круга читателей, в том числе для лиц, принимающих решения в области политики на рынке труда, социальной политики, экспертного и научного сообщества, журналистов.
Epidermoid Cyst arising within an Intrapancreatic Accessory Spleen [ECIPAS] mimicking a pancreatic mucinous cystic neoplasm-a case report with literature review

Background: Accessory spleens are congenital embryological aberrations usually found within the splenic hilum with no clinical significance. An Intra Pancreatic Accessory Spleen (IPAS) is an uncommon benign pancreatic lesion encountered clinically. The occurrence of an Epidermoid Cyst arising within an IPAS (ECIPAS) is exceedingly rare and is often misdiagnosed as a pancreatic pathology such as mucinous cystic neoplasm, cystic degeneration within a solid tumor such as a neuroendocrine tumor, or a lymph node. Case report: A 68-year-old male presented with intermittent post-prandial abdominal pain for over 2 years. Abdominal computer tomography identified a 5.2 cm calcified cyst within the pancreatic tail and a mucinous pancreatic neoplasm/pancreatic pseudocyst was considered in the differential diagnosis. The results of endoscopic ultrasound and fine needle aspiration were indeterminate. Due to persistent abdominal pain, the patient underwent a laparoscopic distal pancreatectomy with splenectomy. A gross examination of the distal pancreatic/splenectomy specimen confirmed a well-demarcated cystic lesion with brownish fluid within the pancreatic tail. Microscopic examination revealed a nonpathological pancreas separated by a fibrous capsule with a large cyst arising within an intrapancreatic accessory spleen. The cyst was lined with multilayered non-keratinized stratified squamous epithelium positive for pancytokeratin, CA 19-9, CK5/6, and p63 with no lymphocytic infiltrates and absent hair/ dermal appendages confirming an epidermoid cyst. CD8 outlined the dendritic network of the littoral cells of the splenic tissue in the cyst wall. Post-operative follow-up at 6 weeks was uneventful. Conclusion: The preoperative diagnosis of ECIPAS is extremely difficult as this entity shares overlapping radiological features with other cystic lesions such as mucinous pancreatic cysts. It is important for anatomic pathologists to recognize and consider the intrapancreatic compartment as a possible site for accessory spleen. As histopathology is the final determinant of this diagnosis, increased clinical awareness with an accurate diagnosis of this entity may prevent patients from unnecessary surveillance and/or extensive oncological-based surgical resection.
