Published: May 2024

Bei der schweizerischen Familienstiftung handelt es sich um eine jahrhundertealte Einrichtung. Doch heute ist sie hinsichtlich Neugründungen klinisch praktisch tot – aus zwei Gründen: Die Familienstiftung wurde in ihrer Zwecksetzung durch den Gesetzgeber und vor durch die Gerichtspraxis aus längst überholten Gründen stark eingegrenzt. Sie dürfen keine Ausschüttungen zu Unterhaltszwecken vornehmen. Ausserdem werden sie prohibitiv besteuert. Am 17. Januar 2024 versuchte das Seminar „Familienstiftungen – neue Perspektiven“ in rechtshistorischer, rechtstatsächlicher, dogmatischer und praktischer Hinsicht eine Lagebeurteilung. Dieser Band enthält die dabei gehaltenen Referate, die einen umfassenden Überblick über die relevanten Themen bieten. Wie der Titel anzeigt, geht es aber auch um neue Perspektiven. Die Hoffnung stützt sich vor allem auf eine Motion von Nationalrat Thierry Burkart „Die Schweizer Familienstiftung stärken. Verbot der Unterhaltsstiftung aufheben“. Geschaffen werden soll ein taugliches Instrument für die familiäre Vermögens- und Nachlassplanung.

Sessment of sustainable development of regions: methodological approaches and algorithms
Authors: Medvid Hanna
Published: May 2024

It is determined that Russia's full-scale invasion of Ukraine in 2022 has attracted considerable attention from the whole world to our country. The escalation of geopolitical conflicts leads to increased confrontation between countries, significantly affecting international relations and the geopolitical situation and causing changes in the global economy. This has severe implications for the global economic balance, international trade, investment, and the overall stability of different regions. Ukraine is experiencing massive migration, both internal and external. In addition, severe damage has been done to critical infrastructure, the housing sector, the economy, the environment, and the social sphere. The loss of territories hurts the regions' social, economic, and environmental development. Regions previously characterized by sustainable development are now experiencing negative consequences of the hostilities. As a result, regions are forced to adapt to new realities, giving preference to flexibility and resilience. The research is devoted to the study and analysis of the problems of assessing the sustainable development of regions, including economic, environmental, and social aspects. Improved methodological approaches and algorithms for determining the level of sustainable development and assessing its impact in the context of war and post-war recovery are proposed. This methodology aims to ensure a comprehensive and objective assessment of the sustainability of regional development, which is an essential prerequisite for effective management and strategic decision-making in an uncertain environment. The study aims to analyze various methodological approaches to assessing the sustainable development of regions in the context of military conflict and post-war reconstruction. The task of the study is to improve methods and algorithms for an objective assessment of the level of sustainable development of regions, which includes an analysis of various aspects of development to ensure a balance between current needs and the needs of future generations. By analyzing different methodological approaches and considering their effectiveness, the author identifies their potential shortcomings and advantages and proposes improvements to these methods to develop targeted management strategies, which will help to choose the best approaches for the post-war recovery of Ukraine's regions in the future. The author has developed his evaluation algorithm aimed at using improved and innovative methods under martial law. The formulas for economic, environmental, and social indices have been improved, which will allow for better consideration of the specifics of military influence at the regional level.
Keywords: sustainable development, geopolitical situation, war, methodological approaches, methodology, algorithm, assessment of sustainable development of regions, assessment of the impact of war, post-war recovery, recovery strategies.
Online Pravda’s Communicative Intentions Regarding the War in Ukraine: A CDA-Based Study of the Website’s Opinion Articles
Authors: El-Astal Mohammed , Al-Mutawa Abdulaziz
Published: May 2024

This research paper, based on Critical Discourse Analysis (CDA), aimed to uncover how the opinion articles published on Pravda.ru discursively depicted the war in Ukraine and the parties involved. To achieve this, two elements of CDA analysis, namely presupposition and structural opposition, were examined. The first element was scrutinized to determine how Pravda.ru depicted the war in Ukraine (RQ1), while the second element was analyzed to understand how Pravda.ru portrayed the parties involved, whether directly or indirectly, in the war (RQ2). For this study, 83 articles were subject to critical discourse analysis, covering the period from February 25, 2022, to February 24, 2023, the first year of the war. The results obtained from this study indicated that Pravda.ru employed various techniques to construct presuppositions and structural oppositions. Pravda.ru portrayed the war as a 'special military operation' and a 'proxy war.' The former, characterized as a euphemism, aimed to mitigate the impact of the word, presupposing that the events did not constitute aggression against Ukraine. The latter presupposed that Russia was a victim of a conspiracy. Furthermore, the results revealed that Pravda.ru used stigmatization and religious affiliations and terms to construct structural oppositions.
Critical Discourse Analysis of Intercultural Communication through the Lens of Multiculturality and Interraciality
Authors: Ramos Jennifer Tan-de
Published: May 2024

Recent research on Critical Discourse Analysis (CDA) has focused on the identity construction of agents within discourse. This study delves into intercultural communication through the lens of multiculturality and interraciality. Employing the CDA framework, the research investigates how online Filipino Chinese writers construct their identities and those of their readers, examining the dynamics of dominance and subordination in selected intercultural discourse. The study is guided by three central questions: how online intercultural writers position themselves in terms of their social identities, how the relationship between the writer and readers is linguistically realized, and how the representations and relationships of the writer and reader manifest in terms of discursive strategies. By concentrating on identity construction through the analysis of linguistic items, the study offers critical discourse analysts an alternative method for unveiling power and dominance in written texts. Furthermore, the examination of discursive strategies allows this CDA study to perceive texts as dual in nature, serving not only as a means for writers to influence their readers but also as instruments to endorse ostensibly positive values. In conclusion, the study presents an approach for analyzing intercultural discourse, enriching the field of CDA with a nuanced understanding of the complex interplay between writer, reader, and text within the rich tapestry of intercultural communication.
Analysis of Gender Discourse Bias and Gender Discrimination in Social Media: A Case Study of the TikTok Platform
Authors: Yin Qingxia , Abdullah Karmilah Binti Binti
Published: May 2024

In the contemporary landscape of new media, social media platforms, particularly exemplified by TikTok, offer female users accessible and cost-effective means for self-expression and communication. However, this study reveals that such platforms, despite their apparent openness and liberality, have not effectively challenged or changed the persistent and deep-rooted issue of gender discrimination that women face. This research adopts a qualitative content analysis and specifically focuses on the TikTok platform, where female users frequently encounter various forms of gender discourse bias and discrimination. The findings suggest that female users on TikTok often face stigmatization through the internet lexicon and the commodification of physical appearance, reflecting broader societal issues of gender inequality and objectification. Simultaneously, a segment of the female user base on TikTok is actively engaging in challenging and negotiating these entrenched stereotypes, striving to redefine their representation in the digital space. Furthermore, the research highlights how the anonymity of the internet, the media’s role in encoding and perpetuating gender stereotypes, and the consumerist traps set by capitalist market dynamics, collectively contribute to an illusory facade of gender equality. This facade obscures the underlying realities of discourse bias and gender discrimination that persist in the digital realm.

USE OF THE WORKING BODY OF THE UNIVERSAL VIBRATORY MILL FOR DRYING GRAIN MATERIAL
Authors: Solona Olena , Tverdokhlib Igor , Kotov Boris , Pantsyr Yuriy
Published: May 2024

One of the most perspective directions of intensification of heat and mass transfer in the processes of drying plant materials and increasing the energy efficiency of drying plants is the application of a vibration field for mixing grain material while moving in the drying chamber. The analysis of existing vibration installations has revealed that the most promising is the usage of vibratory grinding chambers with spatial circulation of material for the implementation of grain heat treatment, in particular drying. As a result, it is proposed to use the proven element base of a vibratory mill as a working body of which grinding chambers with spatial circulation of the load are used.

The article presents the structural and technological scheme of a vibratory thermal drying unit, the structural parameters of the unit, and a mathematical description of the grain drying process. The obtained differential equations constitute a mathematical model of the nonstationary process of continuous drying of grain material and determine the change in time, parameters of grain and steam-gas mixture at the outlet of the grain drying chamber. The constructed mathematical model of the drying process makes it possible to determine the modes of heating and dehydration of grain material during circulation in a vibrating chamber with a conductive energy supply and partial vacuuming of the chamber, to expand the technological capabilities of the "vibrating mill" type installations. The graphical dependences of the temperature and moisture content of grain over time, the data for which were determined experimentally, are presented when a monolayer of grain of mass m is heated on a heating surface of area F at a stabilized surface temperature θn. In this work, the kinetics of drying and heating of grain were obtained, which were used to calculate the parameters of the vibrothermal drying unit. Also, using the results of the experiments, the performance indicators of the vibration dryer created on the basis of the grinding chamber of the vibrating mill were determined.
PWM CONTROL OF THE ELECTRIC DRIVE IN MECHATRONIC MODULES ACCORDING TO THE PRINCIPLE OF SPACE-VECTOR MODULATION

Published: May 2024

In mechatronic modules, the use of a vector control system for asynchronous motors includes the need to use an additional computing unit. This block is responsible for estimating the current angular position of the rotor flux coupling vector. This process is based on solving a system of differential equations that correspond to the mathematical model of the engine. To implement an effective vector control system for AC drives, high-performance microcontrollers with a rich range of integrated peripherals are required. These devices must require minimal computing resources from the central processor for their normal operation.

Modern advances in the development of processors for signal processing, such as DSP processors from companies such as INTEL, TEXAS INSTRUMENTS, ANALOG DEVICES and others, allow to ensure high performance and a wide functional range. A special role is played by universal generators of periodic signals, which ensure the use of modern inverter control algorithms, in particular algorithms of vector pulse width modulation.

One of the main advantages of vector control of asynchronous motors is the absence of disadvantages of voltage amplitude regulation, as well as high speed and good output voltage or current shape (which approaches sinusoidal with pulse width modulation). It is also worth noting the significant simplification of the rectifier, which can be uncontrolled, which helps to increase the power factor of the converter in the entire range of voltage regulation.

However, it is important to note some disadvantages of this approach, including the complexity of the inverter circuit and control system, as well as increased losses in the power elements of the inverter due to the high switching frequency of the switches. Despite these shortcomings, vector control is widely used in high-speed positional electric drives of production mechanisms and machines, as well as in drives of complex technical systems with deep speed regulation in the area of "small" movements.
MATHEMATICAL MODELING OF THE PROCESS OF MOVEMENT OF GRAIN MATERIAL ON THE SURFACE OF A SIEVE OF A VIBRATING PNEUMATIC PULSE SEPARATOR
Authors: Stepanenko Sergey , Volyk Daryna , Kotov Boris , Zamrii Mykhailo
Published: May 2024

The results of a theoretical study of the movement of grain material on the surface of a unfailing sieve of a vibrating pulse separator are presented. The paper presents the power and kinematic model, geometric characteristics of the surface of the sieve of a vibrating pneumatic pulse separator in static, and kinematic processing parameters. Calculations based on the proposed model allow determining the forces of movement, velocity, and acceleration of seeds in the grain medium under the combined action of vibrations and pneumatic pulse flow.

The following conclusions were drawn as a result of the research and analysis of the generated forces according to the developed mathematical model: the greatest influence on the process of moving grain material, both in the horizontal and vertical directions, is exerted by the force of impulse (pulsation) of the air flow, the pressure force above the overlying layers of grain material (for seeds in the middle part and on the surface of the sieve without a dip), friction forces, seed weight, and the Archimedean force; in order to intensify the process of fractionation of the grain medium, increase the productivity of the vibrating pneumatic pulse separator, it is necessary to increase the force of the pulsating air flow, the inertia of the oscillatory motion, friction and lateral pressure on the seeds in the grain medium.

To solve this problem, it is necessary to optimize the amplitudes and frequencies of oscillations of the unfailing sieve of the vibrating pneumatic pulse separator. The analysis of the mathematical model showed the feasibility of using a vibrating unfailing sieve surface with the simultaneous interaction of the injecting pulsating air flow under the sieve to separate grain material by seed density. It has been established that in order to intensify the separation of grain material into fractions, while increasing the productivity of the technical means, it is necessary to increase the force of the pulsating air flow, friction forces, and lateral pressure.

The dynamic model of the movement of grain material displacement and recombination is scientifically substantiated and technological recommendations for the separation of grain material into fractions by seed density using the proposed technical means of a vibrating pneumatic pulse separator with the use of a patented method of its separation are developed.
MATHEMATICAL MODEL OF VIBROACOUSTIC SIGNAL OBTAINED DURING VIBROACOUSTIC DIAGNOSTICS OF MACHINES
Authors: Borysiuk Dmytro , Tverdokhlib Igor , Kupchuk Ihor , Kovalchuk Oleg
Published: May 2024

The modern stage of development and use of diagnostic tools is characterized by intensive computerization. Computer technology is used at all stages of designing diagnostic systems, but, of course, it plays the main role in the process of processing and analyzing diagnostic information.

Vibrodiagnostics is based on measuring the characteristics of vibration processes (displacement, speed or acceleration) that are formed during the interaction of parts of a working machine or mechanism, and their analysis by various methods. The vibroacoustic signal has a complex structure that depends on the dynamics of the mechanism, as well as the type and nature of the interaction of the nodes that make it up.

Acceleration is a derivative of speed and can be used to assess the tendency of a machine's technical condition to change. The change in the amount of movement (amplitude of vibration) in the frequency spectrum is used in the tasks of finding various defects.

The vibroacoustic signal has a complex structure, contains a useful component and an obstacle that prevents accurate recognition of the information contained in the signal. In addition, distortions occur when the diagnostic signal passes through the channels from the source to the sensor.

The mathematical model of the vibroacoustic signal obtained during the vibroacoustic diagnosis of machines is presented in the article. It was determined that the time function s(t) specified in the interval [0, T] serves as a mathematical representation of the signal, which will be used to consider methods of its transformation in order to highlight its parameters and diagnostic features. The ability of the signal to provide information about the state of the object is due to the fact that some of its properties can change depending on the state change. In order for the diagnostic problem to be solved, different signals must correspond to different states of the object, and this correspondence must be mutually unambiguous.

Supervisory Controller Design to Enforce Desired Properties in Systems Modeled by Timed-arc Petri Nets
Authors: İftar Altuğ
Published: May 2024

Discrete-event systems which are modelled by timed-arc Petri nets are considered. A supervisory controller design approach for such systems for enforcing some desired properties is proposed. For the representation of the state of the system, the proposed design approach uses stretching. The designed controller enforces Lˆ-boundedness (for any given bound vector Lˆ) and reversibility simultaneously, whenever it is possible to design such a controller. Furthermore, ∆-liveness is also enforced, where ∆ is the largest possible subset of the set of transitions for which it is possible to design such a controller. Furthermore, the designed controller is maximally permissive in the sense that no transitions are disabled unnecessarily and the reachability set of the controlled system is the largest possible set in which boundedness and reversibility can be enforced simultaneously. To demonstrate the proposed approach, an example controller design is also presented for an automated manufacturing system.

Prior to using CNF loaded with fertilizer, it was imperative to know the desired level of CNF to be used that is suitable for plant growth. Hence, the aim of current research is to investigate the impact of CNF on seed germination and seedling growth using Jowar (Sorghum bicolor) a monocot and Chick pea (Cicer arietenum) a dicot crop. The parameters, to observe the seedling growth in presence of different concentrations of CNF (0.5 to 15 ppm CNF in Soilrites); included percentage germination and seedling vigor, seedling growth (shoot and root length as well as number of leaves and lateral root), mitotic index, auxin level, and primary metabolites of the seedlings. Presence of CNF in soil was inhibitory to Jowar seeds , where as it promoted germination percentage of Chickpea. Once the seed germinated seedlings of both Jowar and Chickpea showed positive response in morphogenic growth, in Mitotic Index, Chlorophyll content as well as primary metabolites. Chickpea was found to be more synergistic to CNF than Jowar.

The non-destructive technique known as Electrical Resistivity Tomography (ERT) has been used in the analysis of historical buildings in recent years. It provides insights into the internal structure of the structural elements, such as layer thicknesses, and potential irregularities. In this investigation the ERT technique was applied to the ancient San Ignacio Bridge, located in the state of Aguascalientes, Mexico. The resulting resistivity profiles unveil the primary construction stages of the bridge, which corroborate and enhance the historical information regarding its construction phases. Additionally, the profiles indicate the presence of moisture concentrations in the pavement fillings, which could be attributed to rainwater infiltration. The usefulness of the ERT technique applied to edified patrimony is demonstrated in this study.

Three bis- or tris-brominated 2-trifluoromethylquinolines have been successfully applied in palladium-catalysed Sonogashira reactions, leading to several examples of alkynylated quinolines in good to excellent yields. Optical properties of selected products have been studied by steady state absorption and fluorescence spectroscopy which give insights of the influence of the substitution pattern and of the type of substituents on the optical properties.
FIFO Method Improvement and Adjustment Design for PT. ABC Warehouse Plans
Authors: Nirmala Ira
Published: May 2024

Face film company PT. ABC requires an efficient and organized storage system to secure raw materials and finished products. However, warehouses currently experience problems with random storage, which causes human error, overstocking, and potential product damage. This research aims to design layout improvements and adjustments to the FIFO (First in First Out) method in PT A B C's warehouse plan. The research method used is qualitative with observation, interviews and literature study. Observation results show discrepancies in warehouse layout that disrupt operational flow, as well as the need for restructuring and improving the management system. Through design improvements, such as rearranging the layout, more strategic placement of goods, and implementing the FIFO method, it is hoped that it can increase warehouse operational efficiency, reduce the risk of goods damage, and speed up the delivery flow to customers. More comprehensive improvements, including inventory management and staff training, are also needed to ensure the successful implementation of an effective FIFO system. Thus, this research contributes to improving warehouse management and operational efficiency of PT. ABC.

The Far Eastern freshwater mussel Sinanodonta lauta has recently been recorded in European Russia outside of its native range. As an invasive species affecting native ecosystems, this mussel is still poorly investigated in many aspects, including population genetics. In this study, we describe for the first time eight microsatellite loci that were developed based on a previously published set of microsatellite markers of the Chinese Pond Mussel (Sinanodonta woodiana).

Published: May 2024

El COVID-19 transformó el proceso de enseñanza y aprendizaje, enfatizando el uso de las Tecnologías de Información y Comunicación y Entornos Virtuales del Aprendizaje; sin embargo, la transición de un grado a otro en esta modalidad no ha sido satisfactoria en la mayoría de los casos. El objetivo del estudio se enfocó en la identificación de los factores que contribuyen al fracaso de esta transición, haciendo hincapié en la necesidad de un enfoque integral en la planificación curricular para abordar las complejas dinámicas educativas en tiempos de pandemia. Metodológicamente, se llevó a cabo una revisión sistemática siguiendo los protocolos de la declaración PRISMA. Este enfoque se respaldó en un marco inductivo, adoptando un paradigma positivista y empleando un enfoque cuantitativo. El diseño documental exploratorio ha guiado la búsqueda de evidencia relevante en diversos motores de búsqueda, como WoS, Dialnet, Redalyc, Scopus, Science Direct y Springer, entre otros. Se aplicaron criterios de inclusión, lo que permitió seleccionar un total de 27 artículos para su análisis. Entre las conclusiones más destacadas se resalta que los factores que influyen en la transición educativa comprenden aspectos tanto endógenos como exógenos. En el ámbito endógeno, se centran en el proceso de transición y se hallan intrínsecamente ligados al estudiante y su contexto, abordando elementos cognitivos y socioemocionales. Por otro lado, en el ámbito exógeno, se reconoce al estudiante como el actor principal, teniendo en cuenta los procesos didácticos, sociales, culturales y las dinámicas de convivencia que ejercen un profundo impacto en su experiencia educativa.
