Authors: Morales-Herrera Ileana , López-Vargas Elena , Fallas-Rodríguez Pilar , Pérez Ana M.
Published: November 2024

Introducción. Dado que el proceso de desarrollo de un producto no está completo si no se conoce su tiempo de vida útil, la obtención de un producto novedoso como una premezcla para pancakes a base de harina de maíz morado planteó la necesidad de determinarla. Objetivo. Estimar la vida útil de una premezcla para pancakes a base de harina de maíz pujagua (Zea mays L.), utilizando el análisis de datos de regresión lineal y de estadística de supervivencia para comparar ambas metodologías. Materiales y métodos. El estudio se efectuó en el Centro Nacional de Ciencia y Tecnología de Alimentos (CITA) de la Universidad de Costa Rica, de 2018 a 2023. Se realizó el estudio de almacenamiento de la premezcla para pancakes con tres repeticiones, en una cámara a 25 °C y muestras control a -18 °C por 7,5 meses, con nueve tiempos de muestreo, cuya frecuencia fue de 26 días. Para los pancakes se analizaron las variables sensoriales masticabilidad y sabor atípico; para la premezcla se seleccionó la variable olor atípico. Se realizó una prueba de agrado con consumidores (n=100). Con estos resultados y los datos del panel con jueces entrenados, se calcularon dos valores de vida útil, uno con el método de punto de corte y otro con la distribución de Weibull. Resultados. La variable sensorial que limitó la vida útil de la premezcla fue la masticabilidad. Con la primera metodología se estimó un valor de vida útil de 124 días y con la segunda el valor fue de 265 días a 25 °C. Conclusiones. El método de punto de corte fue más conservador y sensible a las variables críticas seleccionadas. El método de distribución de Weibull resultó más práctico, pero se debe ser cuidadoso al evaluar productos poco familiares o de los cuales los consumidores manejan escasa información.

Simulation modeling of artillery operations in computer games: approach based on Markov processes
Authors: Maksymov Oleksii , Toshev Oleksandr , Demydenko Volodymyr , Maksymov Maksym
Published: November 2024

The object of this research is an approach to simulating the combat operation of artillery in computer games based on Markov processes. In modern computer games, an important role is played by the realism and plausibility of combat simulation. One of the most difficult and at the same time most interesting tasks is the modeling of artillery operations, where it is necessary to take into account numerous factors affecting the effectiveness of combat work.
The research was aimed at improving the methods and models of controlling the combat work of artillery under the conditions for the firing position change and the presence of external disturbances. The use of stochastic models allows more accurate modeling of the behavior of artillery units, taking into account the random nature of many parameters, such as projectile speed, reload time, and the probability of detection by enemy forces.
The proposed approach includes the development of a simulation model that allows determining optimal strategies to achieve maximum effectiveness of combat work. The model is based on Markov processes, which allows taking into account possible system states and probable transitions between them. This allows not only to simulate combat operations, but also to predict the results depending on different scenarios.
The results of the study show that the use of Markov processes in the simulation of combat operations can significantly increase the realism and efficiency of artillery operations in computer games. This opens up new opportunities for game developers to create more immersive and authentic gaming experiences.
The proposed model can be used as a basis for further research and improvement of combat simulation methods in computer games. It can also be used in military simulators and simulators where realistic combat conditions must be taken into account.

Authors: Davydiuk Oleksandr
Published: November 2024

The object of this research is a set of management and regulatory methods of state influence on the technology transfer of Ukraine in the context of the implementation of the global model of sustainable development policy. Methods and techniques of public regulation of technology transfer in Ukraine and its compliance with the requirements of sustainable development are studied. The analysis and generalization of the existing world and international approaches to the definition of sustainable development policy established that technology transfer is one of the key objects of managerial influence. It has been proven that the existing regulatory model of technology transfer in Ukraine, formed without taking into account the goals of sustainable development, does not meet its strategic development objectives. The expediency of improving the existing concept of regulation and management of technology transfer in Ukraine in order to eliminate the identified inconsistencies is substantiated. Recommendations have been made regarding directions for improving regulatory and management approaches to determining technology transfer in Ukraine. The necessity of making changes to the provisions of the Law of Ukraine «On State Regulation of Activities in the Field of Technology Transfer» has been proved, with the aim of bringing it into line with the international policy of sustainable development.
The research is aimed at the formation of general theoretical foundations for the improvement of managerial and regulatory methods of technology transfer in Ukraine. The research results can be used in the improvement of public rules of technology transfer, the formation of strategic public management decisions, state technological policy and serve as a basis for further scientific research on these issues. The conclusions obtained in the course of this research can be used to solve issues and problems of improving the current legislation of Ukraine to the requirements of international agreements and documents.
An application of the dynamic stiffness concept for vibration of three-dimensional cracked overhead crane
Authors: Trong Dang Xuan , Khiem Nguyen Tien
Published: November 2024

A simplified model is proposed for modal analysis of cracked 3D-framed overhead crane of H-form frame using the well-known dynamic stiffness method. First, the dynamic stiffness of a cracked beam is derived as the inverse of the frequency response function and used for establishing a model of the cracked beam called dynamic stiffness one. Then, the dynamic stiffness model of cracked beams is employed for representing two supporting beams in the H-form frame crane. So that a simplified model of the overhead crane is conducted as a beam with artificial elastic supports of stiffness obtained above for supporting beam. Finally, the free vibration problem of the simplified overhead crane is formulated and solved for the crane fundamental frequency analysis in dependence upon crack parameters and supporting positions. Numerical computation is accomplished for illustrating the proposed theory and providing some conclusions on the simplified model of 3D overhead cranes.
Digital afterlives: A verbatim play about death in a digital age
Authors: Mooney Missy
Published: November 2024

Death could be considered the ultimate uniting factor (it comes for us all). However, it is not a homogenous occurrence but an experience as individual and nuanced as the lives we live. Consequently, Digital Afterlives: A Verbatim Play About Death in a Digital Age was created not as a prescriptive but descriptive research output that honours the nuance and subjectivity of experiences of loss and individual grief journeys. Constructed entirely from empirical materials collected in recorded interviews, the play illuminates some of the experiences encountered by bereaved New Zealanders as they navigate the contemporary digital griefscape. The testimony included in the play was gathered as part of a larger research project titled Digital Afterlives and Memorialisation: A study into emergent online remembrance practices which was funded by the University of Waikato Strategic Research Fund.

Objective the paper-based OSCE (Pa-OSCE) scoring system has several drawbacks, including significant paper waste and being time-consuming. This study aims to assess examiner satisfaction with the On-OSCE scoring management system, identify and weigh the potential benefits of the innovation, and promote its use. Method using a cross-sectional study design, we developed satisfaction inventory consisting of four domains: time-saving, user-friendliness, prospective application, and objectivity. This inventory was used to compare satisfaction scores between two examiner groups (a total of 67 subjects). Results the 20-item satisfaction inventory demonstrated high validity and reliability (0.98 and 0.97, respectively). The average scoring time was significantly shorter in the online scoring management system group (p<0.001). Both the total satisfaction score and the scores for each domain were significantly higher in the online scoring management system group compared to the paper-based scoring management system group (p<0.001). Conclusion a high proportion of the examiners provided positive feedback on the online scoring management system. The online scoring management system saves the time to score, and is more objective, easier to use, and is recommended for implementation. Online scoring management systems can be implemented in nursing education institutions globally to improve scoring efficiency. Additionally, the 20-item satisfaction inventory can serve as a benchmarking tool to assess educators worldwide.

Relationship between solar radiation and meteorological variables in predictive models for crop yields
Authors: Adam Abdelkarem M. , Zheng Yuan
Published: November 2024

ABSTRACT Knowledge of the complicated correlation between meteorological variables and crop yield is crucial for food security and agricultural sustainability. This study aimed to investigate how incident solar radiation has affected crop production in the Gadarif region of Sudan over the last 41 years. Using a predictive framework, trends in annual incident solar radiation and temporal variations during sorghum and sesame growing seasons were examined and machine learning (ML) with Extreme Gradient Boosting (XGBoost), Boosted Regression Forest (BRF), and K-Nearest Neighbors (K-NN) was used to predict crop yield. Significant relationships between incident solar radiation indicators and crop yields were identified via detrending approaches and correlation analyses. Results indicate a significant inverse correlation between solar radiation and sorghum yield, and a positive correlation between sesame yield and solar radiation. For both sorghum and sesame yield, K-NN was the most accurate model, demonstrating the significance of incident solar radiation and temperature in predicting crop yield. These findings highlight the potential of ML to improve agricultural forecasting models and inform adaptive agricultural practices in the region. In general, this study provides valuable insights into the dynamic relationship between incident solar radiation and crop yield, emphasizing the importance of considering meteorological factors in agricultural planning and management.

Enhancing viability and vigor of deteriorated true shallot seeds (Allium cepa var. ascalonicum) through ultra-fine bubble and plasma-activated water priming
Authors: Raga Yuan , Widajati Eny , Ilyas Satriyas , Purwanto Yohanes Aris
Published: November 2024

ABSTRACT: Ultra-fine bubbles (UFB) and plasma-activated water (PAW) are well-known water treatment technologies that have recently been explored for seed priming. Most results demonstrated improvements in seed vigor and viability, hypothesized to be due to reactive oxygen species (ROS). This study aimed to determine the optimum priming technique using UFB and PAW for deteriorated true shallot seeds (TSS). The TSS with various expiration dates and low viability (germination rate <80%) were primed for 24 hours with UFB water (dissolved oxygen levels of 18 and 24 mg.L-1) and PAW (five ozone concentrations, 0; 0.1; 0.5; 1.0; 4.0 mg.L-1 and three exposure times (10, 20, and 30 min) at separated experiment. The results showed that UFB and PAW effectively improved seed physiology. It increased the germination rate and radicle emergence to >80%, similar to fresh TSS. The UFB water treatment dissolved oxygen levels resulting in similar improvement, whereas PAW with 0.1 mg.L-1 ozone was the optimum treatment level. The exposure duration demonstrated variability in the PAW priming effectivity. Internal seed ROS alterations due to UFB- and PAW-produced ROS improved TSS pre-germinative metabolism, i.e., hydrolytic enzyme activity, respiration rate, and membrane integrity. Thus, it potentially underlined the viability and vigor enhancement of deteriorated TSS.

The paper is concerned with the problem of determining the size of the plastic strain region when studying the properties of materials under dynamic shear loads. As an example, the behavior of AMg6 alloy specimens in dynamic tests on the split Hopkinson pressure bar was studied by applying a Photron FASTCAM SA-Z 2100K high-speed camera and DIC technology. The shear strain fields and the width of the strain localization region were determined experimentally. The size of the plastic strain region evaluated through numerical modeling correlates well with the results of the experiment determining the size of this region with the use of high-speed camera and DIC technology. The investigation by means of numerical modeling techniques has shown that in the specimens being considered the shear component of the strain tensor in absolute value significantly prevails over the axial component.
An experimental study of the mixing of liquids in a continuous-flow microchannel under conditions of Rayleigh-Taylor instability

Published: November 2024

This study experimentally investigates the influence of Rayleigh-Taylor instability on the liquid mixing process in a flow-type microchannel. We investigated a two-layer liquid-liquid system consisting of a denser aqueous solution of potassium permanganate (upper layer) and less dense pure water (lower layer) with a fixed density gradient. A colorimetric method based on the dependence of light absorption by solutions on the concentration of the dissolved substance was used to reconstruct the two-dimensional concentration field. Based on the obtained data, we analyzed the spatial structure of convective flows and the degree of liquid mixing along the channel. The studies were carried out at low Reynolds numbers, which precludes the development of turbulent flow, and across a wide range of Richardson numbers that indicate the ratio of buoyancy to inertial forces in the formation of convective structures. We found that at high Richardson numbers, the development of Rayleigh-Taylor instability ensures almost complete mixing of liquids within five calibers from the channel inlet. Reducing the Richardson number by increasing the flow rate through the channel leads to a slowdown in the instability development and, consequently, in a significant decrease in mixing efficiency along the channel. We demonstrated that with optimal values of governing parameters, the characteristic liquid mixing length can be reduced by an order of magnitude compared to pure diffusive mixing scenarios. The obtained results demonstrate the effectiveness of convective instability mechanisms in controlling mass transfer processes in flow-type microchannel systems.

Esta propuesta reflexiva fue realizada con la finalidad de establecer de forma didáctica un análisis reflexivo e histórico-comparativo entre los aspectos sinérgicos y sistemáticos existentes entre la estadística y la administración como áreas transversales del conocimiento, aplicables a cualquier ciencia empírica. Ambas disciplinas exponen estructuras aplicables a cualquiera de las múltiples ciencias fácticas o empíricas: ciencias naturales, biosociales, políticas y ciencias sociales; por un lado, la estadística como soporte fundamental de la aplicación del método científico formal para obtener nuevos conocimientos basados en la experimentación y en la observación, y por otro lado, la administración como el conjunto de técnicas encargada de planificar, organizar, direccionar y controlar los recursos disponibles, ya sean humanos, materiales, financieros, del conocimiento, tecnológicos, entre otros. Estas reflexiones invitan a las escuelas de negocios a dar el paso para incluir en los procesos de formación de profesionales no solo el ámbito técnico fundamentado en las ciencias naturales, sino también expandirse hacia las ciencias empíricas, las ciencias sociales, para generar una concepción administrativa transversal; en donde no todo debe ser considerado un “saber-hacer”, sino más bien un “entender-hacer”, comprendiendo así estos conocimientos desde sus fundamentos y competencias, incluyendo aspectos de la lógica práctica y emancipadora.
Influence of Additives on Crystallization of Calcium Phosphates from Prototypes of Blood Plasma
Authors: Golovanova OA
Published: November 2024

The paper presents the results of studies on the effect of additives on crystallization in solutions simulating the composition of human blood plasma. Synthesis from prototypes of human blood plasma in the presence of organic and inorganic additives was carried out, and it was found that the obtained solid phases consisted of octacalcium phosphate, B-type carbonate hydroxyapatite, and vitlocite. The effect of additives (magnesium ions, alanine, and glycine) on the crystallization of calcium phosphates was studied. It was found that the presence of additives in the model solution reduces the crystallite size and the fraction of carbonate hydroxyapatite in the solid phase. The bioactivity of synthetic samples was studied, and kinetic characteristics were established. A study of thermal transformations.
A Multitrack Technical Ear Trainer
Authors: Garland Kevin , Ronan Malachy , Bassett Mark
Published: November 2024

Technical ear training programs generally focus on engaging learners in tasks to increase their sensitivity to various auditory attributes. However, very little work has been done on integrating ear training into a multitrack environment where contextual factors dictate the employment and configuration of audio processing tools for mixing engineers. For novice audio engineers, transference of critical listening skills to multitrack scenarios within a conventional digital audio workstation may prove challenging without guidance from an experienced engineer. This report describes the design and development of ReFlow, a novel reverberation training prototype that embeds technical ear training within a dedicated multitrack environment to facilitate bespoke matching tasks based on expert performance. Expert performance is communicated to the end user via traditional and cognitive apprenticeship methods in which learners recall parameter configurations in the context of a multitrack mix while engaging with underlying conceptual knowledge provided by the modeled engineer.
Banking System of the Russian Federation: Theoretical and Practical Issues of Ensuring the financial Sovereignty of the State
Authors: Kukushkin V. M.
Published: November 2024

This work is devoted to two main issues: understanding the category of “sovereignty” and the role of the banking system in ensuring the financial sovereignty of Russia. Based on the analysis of doctrinal sources, including past historical eras, sovereignty is considered not only as a constitutional and legal institution, but as a general legal institution as a whole. The types of sovereignty presented in the literature are examined and the question is raised about the need to achieve terminological certainty, a conclusion is made about the possibility of the existence of only such an integral part of state sovereignty as economic, including financial sovereignty, which is understood as the financial security of the state from external and internal threats. The issues of ensuring financial sovereignty in relation to the functioning of the Russian banking system are explored. It is proposed to enshrine financial sovereignty in legislation as a principle — a norm of the banking system. It is stated that the condition for ensuring financial sovereignty is the resolution of a number of internal problems, which include the formation of trust in the banking system, financial fraud, and unfair practices. Important issues are building an effective banking system and systematizing banking legislation.
On the Nature of Digital Rights and Low-volatile Digital Currencies
Authors: Iontsev M. A.
Published: November 2024

The article discusses topical issues related to the nature of tokens. First, the author pays attention to the proximity of the legal nature of tokens to uncertified securities, which are also a mechanism for accounting for property rights, and not an independent type of property right. Secondly, the author resorts to a comparative legal method when studying the institute and points to the existence of a mechanism for creating digital forms of certification of property pairs in France and Germany. Thirdly, the article contains special interpreted phrases “without reference to a third party” of article 141.1, paragraph 1, of the Civil Code of the Russian Federation, which does not impose prohibitions on any types of intermediation in the market of tokens. Fourthly, the article analyzes the ratio of low-volatile digital currencies to tokens, indicates the difference in their legal nature.
Legal Regulation of the Use of Artificial Intelligence Technologies in Banking Activities
Authors: Sizemova O. B.
Published: November 2024

The article, based on an analysis of the current legislation of Russia and the experience of legal regulation of developed countries, draws conclusions about the need to improve the concept of artificial intelligence technologies based on a criteria-based approach. The author proposed a classification of AI technologies according to the intended purpose of use: used for public purposes; used for commercial purposes; AI technologies used for non-commercial purposes. In banking, AI technologies are always used for commercial purposes, and in the financial sector, developers and people using AI are the same. The author concludes that a presumption of guilt has been established for financial organizations using AI technologies in relations with consumers. The proposed classification may be useful in connection with the creation of a system of regulation and supervision, since the current measures of responsibility of financial organizations should be considered insufficient.
Compensation for Losses in the Process of Bank Resolution
Authors: Pleshanova O. P.
Published: November 2024

The article concerns the current judicial practice by applying the provisions on damages in the bank resolution by The Bank of Russia (par. 2 of clause 5 of The Bankruptcy Act, entered into force on the 8’June, 2018). This rule attracted the attention of researchers from the very beginning due to its specificity: the losses have been called untypical since their amount is determined in advance by law. Now the courts reject to apply these provisions with reference to the absence of retroactive force; in other situation the court has required to examine the circumstances of the case more thoroughly. Analysis of the norm shows that it doesn’t comply with the general provisions of the Russian Civil Law and is unlikely to be successfully applied at all. Herewith The Bank of Russia could use another legal means to achieve the goal of compensation for losses.
