La multiafiliaciÃ³n. Reflexiones constructivas
Authors: Repiso Rafael , Aguaded Ignacio , Montero-DÃ­az Julio
Published: June 2023

En las Ãºltimas semanas ha habido controversia en torno a la afiliaciÃ³n mÃºltiple debido a varios escÃ¡ndalos surgidos en el Ã¡mbito cientÃ­fico espaÃ±ol. En EspaÃ±a, esta prÃ¡ctica no estÃ¡ regulada y es incompatible con la exclusividad que exige la administraciÃ³n pÃºblica a sus contratos a tiempo completo. En el artÃ­culo se analizan los aspectos positivos y negativos que tienen para las instituciones y para los acadÃ©micos que llevan a cabo esta prÃ¡ctica. Igualmente, se realizan una serie de recomendaciones sobre cÃ³mo podrÃ­an las instituciones generar acuerdos donde todos los actores encuentren beneficio en una afiliaciÃ³n mÃºltiple y a la vez eviten el fraude. Los autores del trabajo concluyen que esta prÃ¡ctica, desarrollada de manera honesta y pactada con las instituciones involucradas, promueve ventajas destacadas. En el caso espaÃ±ol, se hace necesario regular estas prÃ¡cticas dentro de las universidades pÃºblicas en el marco de convenios y acuerdos individuales.

Published: June 2023

This article discusses the artistic trends of the 60s of the twentieth century. The aesthetic concepts of socialist realism, Romanticism, modernism and postmodernism are discussed, as well as the peculiarities of their development in Kazakh literature. The article analyzes the ideological and aesthetic concepts that opposed the socialist realism of that period. The works published during the period of post-socialist realism reflect the ways of development of modernist aesthetics. The features of new characters in literature are revealed. In addition, the article scientifically analyzes the formation of artistic systems and their methods with such features as a special spiritual connection of a person with the surrounding life of that era, personal relations between society and the individual. It is known that in the Kazakh prose of the 1970s and 80s, the well-established modernist aesthetics is closely connected with neo-mythologism. Based on this, relying on the conclusions of the world literary science, we will focus on the problem of neo-mythologism in the works of Kazakh writers. The article describes the influence of modernism and postmodernism on modern Kazakh prose and aesthetic principles of neo-mythologism, reflected in the national prose of the 70s of the twentieth century. The article makes a comparative analysis of scientific concepts of domestic scientists, as well as world research works.

The frame structure of the mental vocabulary in the Kazakh language is considered in this article by comparing the lexical-semantic groups of verbs in the Kazakh and other Turkic languages. Their semantic field is analyzed based on semantic, functional, emotional and expressive features of verbs in the Kazakh language. When defining thematic groups, particularly, verbs that nominate the spheres of mentality, the authors use as a basis the main features, meanings and functions in the context, as well as the functional characteristics of each word. Particular emphasis is placed on the fact that the main feature of the verb is clearly seen in its semantics. The authors classify the verbs of the Kazakh language into eight groups depending on the features of the semantic field. Taking into account the issue of the complexity of verbal semantics in linguistics, it is concluded that the classification of the meanings of mental verbs is very difficult; the definition of its essence and grouping according to their semantics is also a complex linguistic phenomenon, therefore the proposed classification may be conditional and cannot completely solve the problem of classification of mental verbs.

Published: June 2023

Among the problems of sociolinguistics, the problem of language planning occupies a special place. Language planning refers to activities undertaken in a speech community to influence language function, structure, or language acquisition. Language planning is often regarded as a top-to-bottom activity that is government-controlled. In this article, the main focus of the authors was on prestige planning, which is the main category of language planning. Prestige planning proves that the scope of language can be expanded from the bottom-to-top with soft power. In this study, an overview of scientific research related to the issue of prestige planning was presented. It is argued that prestige planning is the basis of successful language forecasting. The importance of using soft power in the implementation of language policy and planning is noted, as well as examples of the rational use of soft power tools in the implementation of prestige planning in Kazakhstan. The efforts of language movement activists and significant changes in the language situation were distinguished. Based on the sociolinguistic survey, the role and importance of languages in Kazakhstan for the respondents was studied. Opinions of the survey participants on how to make the Kazakh language fashionable were revealed. This study shows that the foundation of the Kazakh language has really strengthened, its reputation has increased, and the desire to study and use it in everyday life has increased. In addition, the interest in English, which is the language of international communication in the field of business, science and technology, is also increasing
The Media Poetry of Nikolai Rubtsov in the Internet Poetic Discourse of the 21st Century
Authors: Bejenaru L.
Published: June 2023

This article considers the problems of Internet discourse and media space itself as one of the main characteristics of Internet discourse. The characteristics of media texts, an important product of media space, are analyzed. The necessity of studying media-poetry, which is a synthesis of poetry and various media spaces, is revealed and justified. The author uses the creative work of the famous Russian poet N. Rubtsov as an example. On the basis of the research, the author proves that Nikolai Rubtsov is the most sought-after Russian poet on the Russian-language Internet. The author argues that media-poetry in the XXI century poetic Internet discourse gives the poet's work a postmodern sounding. The urgency of the article lies in the fact that the study of the language of the Internet is in its infancy; so far few works have been devoted to the subject. The study of the Internet language is promising and has a number of aspects which are waiting for their researchers.

The optimal conditions of catalytic hydrogenation of oil sludge (Atasu-Alashankou) and the change in the kinematic viscosity of the fraction to 350℃ from the studied factors using the method of probabilisticdeterministic planning were experimentally determined. During the hydrogenation process of oil sludge, the maximum total yield of light fractions reached 62.1 %, and the kinematic viscosity decreased from 2.2 to 1.2 mm2/s. It was established the initial hydrogen pressure and the amount of added nanocatalyst microsilicate with cobalt (catalyst 1) have the greatest influence on the yield of the middle fraction from oil sludge under experimental conditions. It was shown that catalyst 1 increases the yield of diesel fraction components during the hydrogenation process of oil sludge. For the first time, we established the individual and group chemical composition of the fraction up to 350℃ before and after processing. The use of nanocatalyst 1 in amounts of 1.2–1.5 % led to an increase in the yield of the fraction up to 350℃ and diesel fraction components. This is due to the yield of paraffinic hydrocarbons increasing from 57.6 (initial fraction) to 80.7 %, as well as a decrease in aromatic hydrocarbons from 14.1 to 12.9 % and polycyclic aromatic hydrocarbons from 9.56 to 4.3 %.

(E)-1-(2-(4-bromobutoxy)-6-hydroxy-4-methoxyphenyl-3-phenylprop-2-en-1-one was synthesized from the pinostrobin molecule. The tetrahydropyran cycle was opened in acetone under heating (50–60 °C) mixtures of components for 16 hours in the presence of 3 moles of K2CO3 and 1,4-dibromobutane. The resulting substance is a yellow powder of the composition C20H21BrO4, mp 83.7–86.6 °C. The structure of the obtained compound was established on the basis of the data of elemental analysis, IR and NMR spectra. As a result of X-ray diffraction analysis, it was found that the hydrogen atoms in the C8=C9 bond take the transconformation. The rotation of the С1…С6 phenyl ring (flat with an accuracy of ±0.008 Å) relative to the С10…С15 cycle (flat with an accuracy of ±0.004 Å) is 14.3°. In the crystal, the molecules are linked by an intramolecular hydrogen bond O4-H....O1 (distances O-H 0.95(8) Ǻ, O····O 2.469(6) Ǻ, H····O 1.58 (8) Ǻ, angle O-H····O 153(7)°). The formation of (E)-1-(2-(4-bromobutoxy)-6-hydroxy-4-methoxy-1-phenylprop-2-en-1-one can be explained by the ease of the retro-Michael reaction of the pyran ring and the subsequent O-alkylation of the resulting chalcone. Carrying out the reaction in the presence of other bases (cesium carbonate, triethylamine) did not lead to success. The starting substance (pinostrobin) was completely converted into oligomeric compounds.
INTERACTION OF PUBLIC AUTHORITY BODIES AND CIVIL SOCIETY INSTITUTIONS IN THE CONDITIONS OF POWER DECENTRALIZATION
Authors: Vasilieva Lesja
Published: June 2023

The purpose of the article is research and generalization of scientific approaches regarding the interaction of public authorities and institutions of civil society in conditions of decentralization of power. It was determined that civil society and public authorities are in constant interaction, complement each other and depend on each other. A strong legal democratic state cannot exist without civil society. As a result of the study, it was established that the activities of civil society institutions should correspond to the strategic goal of civil society to create conditions for the fullest possible self-realization and satisfaction of the interests of society, individual individuals and their collective associations. It was established that the public-legal type of interaction between civil society and public authorities is characterized by the direct power activity of public authorities, which implement the functions of the state through law-making, law enforcement and control. The private-law type of interaction between civil society and public authorities looks somewhat more complicated, since civil society subjects, not having state-authority powers, can influence public authorities through participation in election procedures, examination of legal acts, monitoring and control It is emphasized that control is only one of a rather large number of types of interaction between civil society and public authorities, which can be defined as activities carried out by subjects of civil society in the forms established by regulatory and legal acts, by observation, assessment and, if necessary, adjustment of activities, results of activities of public authorities for the purpose of ensuring their compliance with predetermined parameters and the goal of increasing the efficiency of such activities.

Authors: Kyryliuk Iryna , Chvertko Liudmyla
Published: June 2023

The purpose of the study is to substantiate the significance and features of volunteer tourism for the social integration of forcibly displaced persons during the russian military invasion. The article proves that the challenges associated with the russian armed aggression against Ukraine necessitated the adoption of effective decisions aimed at social adaptation and integration into the public life of persons who, to avoid the negative consequences of war and temporary occupation, were forced to leave their place of residence and found temporary shelter in other regions of the country. It was determined that volunteer tourism occupies a special place among the measures that contribute to the social integration of forced migrants into life in the territorial communities of Ukraine, where they currently live and plan to stay for a long time. Volunteer tourism ensures the convergence of identities of displaced persons and the communities in which they live the establishment of communication, and formation of harmonious cultural forms between forcibly displaced persons and all other members of society. It was established that in the conditions of the russian military invasion, thanks to the joint efforts of volunteers and the partnership of public organizations, there is an opportunity to implement social projects at the national level, which contribute to the social adaptation of people who were forced to leave their usual places of residence, escaping from the military threat. The organization and conduct of tourist activities helps to establish and create a healthy psychological climate through the active, relaxed communicative activity of the event participants, contributes to their psycho-emotional relief, the formation of a positive mood, and mutual satisfaction with the learning process. The article substantiates that the involvement of caring, active, conscious volunteers in the implementation of projects forms a new culture aimed at the spread of universal human values, peace, freedom, security, humanism, personal growth through awareness of human potential.
Creative potential: Mykola Sadovsky’s theater troupe of 1890–1892
Authors: Veselovska Hanna
Published: June 2023

The proposed publication aims to give a detailed tracing of the creative and organizational activities of Mykola Sadovsky’s theater troupe in 1890–1892 in detail. The artistic practice of this troupe, which belongs to the phenomenon of the theater of Ukrainian coryphaei, is considered as an example of the colonial art of the Russian Empire. The paper explores the stylistic and aesthetic characteristics of individual performances of the troupe, as well as the artistic achievements of its leading performers. On the evidence of the analysis of numerous reviews, memoir reviews of performances, memories and correspondence of artists, it has been proven that the Ukrainian theatrical art of the 1890s was an important factor in the formation of the artistic landscape of the Russian Empire. It determined the tastes, artistic direction, and aesthetic preferences of the general public and elites. And despite the fact that the troupe’s full development in the form of a stationary theater was prevented by the prohibitions of the Russian authorities, its influence on the artistic and intellectual environment of the empire can be called unprecedented.

Alogisms vs. logic inthe “post” and classics controversy
Authors: Shkepu Maria
Published: June 2023

Understanding the collisions of the fundamental dimensions of classical history is not relevant for postmodernism, since postmodernism does not reflect itself in the aspect of fundamentality. As a period of objective and subjective reality finally torn apart into fragments, postmodernity appears as the final deformation of the world history. And, according to Karl Rosenkrantz, such a deformation descends into absurdity, accompanied by the reign of evil, madness and crime. Therefore, postmodernism is not a special direction or period in the development of art — it is an artificially formed period of the crazy political economy of history. This unconscious basic feature of postmodernity causes the disintegration of the entire “ensemble” of modes of social structure, it starts in the components of material production and forms of social consciousness and ends in with what should be considered as the initial attribute of historical life — the essence of man. The article presents defining counterpoints of the classical formation of history and postmodern reality in their categorical meaning

Published: June 2023

The article explores scientific works in which the concept of “national” was studied through the prism of the creative intentions of Ukrainian painters. Based on the analysis of literary sources, it is shown that the formation of the national context of Ukrainian painting in the first third of the 20th century is determined by a number of factors — historical and cultural features of the time, values and artist’s worldview. The actualization of scientific discourse of national art contributed to the in-depth study of the development and functioning of Ukrainian painting of the specified period, creative visions of artists. The research methodology is based on the principles of historicism, the cultural-historical method is applied to clarify the prerequisites, cause-and-effect relationships, reconstruction of the development of Ukrainian painting in a diachronic and synchronous dimension, hermeneutics — to substantiate the progress of Ukrainian painting and its significance for culture. Understanding the vision of Ukrainian painting of the first third of the 20th century in the publications of scientists is based on a review of exhibitions, analysis of works, study of biographies and stages of artists’ creativity. It is argued that in the creative intentions of artists who professed realism or formed the foundations of Ukrainian modernism and avant-garde, the concept of «national» determined the development strategy of Ukrainian painting

Analyzing the Role of Automatic Voltage Regulator towards Excited Synchronous Generators on the Sultan Hasanuddin Training Ship
Authors: Hasiah Hasiah , Mahadir Mahadir , Risal Syah
Published: June 2023

Voltage instability in a synchronous generator can lead to system instability, affecting the quality and ability to transfer power to consumers. The worst-case scenario is load- shedding. To prevent this, the Automatic Voltage Regulator (AVR) is used to control the voltage stability of the synchronous generator. However, the AVR is often damaged, which prompted us to investigate its role in stabilizing the output voltage of the synchronous generator. This study was conducted on the Sultan Hasanuddin Training Ship owned by the Marine Science Polytechnic (PIP) Makassar using experimental research methods. Data collection techniques included observation, measurement, and documentation, and quantitative descriptive methods were used for analysis. Results indicated that the role of the AVR on the Sultan Hasanuddin Training Ship was insignificant since changes in generator load did not result in high fluctuations. The excitation current on the voltage amplifier or the output voltage of the synchronous generator remained within the working limit. This was proven by the generator's rotation speed, which ranged from 1470 to 1500 rpm, and a generator load of 36 to 38 kW.

carefully considered to ensure that the water demand of the students and staff can be met effectively and efficiently. Calculations show that a water demand of 0.35 m3/min is required, and various existing pipe diameters are used, ranging from 65mm for the main pipes, 60mm and 50mm for the header pipes, to 40mm, 32mm, 30mm, 25mm, 20mm, and 15mm for the shaft pipes. However, after controlling for velocity values using Epanet software, it was found that some pipes had values below 1.8m/s and above 2.4m/s, which could compromise system efficiency. Therefore, the effective pipe diameter for the header pipes was found to be 125mm and 90mm, and for the shaft pipes, it ranged from 90mm to 15mm. The results of this study highlight that the clean water piping system in the STIBA building must be carefully designed and evaluated to meet the clean water demands of the students and staff effectively and efficiently. This can be achieved by selecting effective pipe diameters based on the Epanet calculations and ensuring that the velocity values remain within the specified limits.

Agriculture is an activity of managing biological natural resources carried out by humans to produce food, industrial raw materials or energy sources, as well as to manage their environment. Most farmers in Indonesia still use traditional/conventional methods in the grain drying process. However, for large-scale farmers this is certainly a difficult task for mixing grain. For this reason, a system is needed that can stir grain automatically so that farmers do not need to come directly to the drying area. In this study, a grain mixer robot was applied using energy from the sun, and can be controlled remotely. This robot uses solar panels to convert solar energy into electrical energy. This electrical energy is then stored in the battery. This energy will also be used to drive the robot to stir the grain. To move the robot, the user can adjust its direction and speed through an application on a smartphone. From this study, the best remote delay time is around 0.22 seconds, while the average delay time is around 0.8 seconds.

This paper is concerned with the study of global attractors for a new semilinear Timoshenko–Ehrenfest type system. Firstly we establish the well-posedness of the system using Faedo–Galerkin method. By considering only one damping term acting on the vertical displacement, we prove the existence of a smooth finite dimensional global attractor using the recent quasi-stability theory. Our results holds for any parameters of the system.
The distribution semantics in probabilistic logic programming and probabilistic description logics: a survey
Authors: Bellodi Elena
Published: June 2023

Representing uncertain information is crucial for modeling real world domains. This has been fully recognized both in the field of Logic Programming and of Description Logics (DLs), with the introduction of probabilistic logic languages and various probabilistic extensions of DLs respectively. Several works have considered the distribution semantics as the underlying semantics of Probabilistic Logic Programming (PLP) languages and probabilistic DLs (PDLs), and have then targeted the problem of reasoning and learning in them. This paper is a survey of inference, parameter and structure learning algorithms for PLP languages and PDLs based on the distribution semantics.

The advances made in wireless communication technology have led to efforts to improve the quality of reception, prevent poor connections and avoid disconnections between wireless and cellular devices. One of the most important steps toward preventing communication failures is to correctly estimate the received signal strength indicator (RSSI) of a wireless device. RSSI prediction is important for addressing various challenges such as localization, power control, link quality estimation, terminal connectivity estimation, and handover decisions. In this study, we compare different machine learning (ML) techniques that can be used to predict the received signal strength values of a device, given the received signal strength values of other devices in the region. We consider various ML methods, such as multi-layer ANN, K nearest neighbors, decision trees, random forest, and the K-means based method, for the prediction challenge. We checked the accuracy level of the learning process using a real dataset provided by a major national cellular operator. Our results show that the weighted K nearest neighbors algorithm, for K = 3 neighbors, achieved, on average, the most accurate RSSI predictions. We conclude that in environments where the size of data is relatively small, and data of close geographical points is available, a method that predicts the coverage of a point using the coverage near geographical points can be more successful and more accurate compared with other ML methods.

Background: Alzheimer’s disease (AD) and cerebrovascular disease are common, co-existing pathologies in older adults. Whether the effects of cerebrovascular disease and AD biomarkers on cognition are additive or synergistic remains unclear. Objective: To examine whether white matter hyperintensity (WMH) volume moderates the independent association between each AD biomarker and cognition. Methods: In 586 older adults without dementia, linear regressions tested the interaction between amyloid-β (Aβ) positron emission tomography (PET) and WMH volume on cognition, independent of tau-PET. We also tested the interaction between tau-PET and WMH volume on cognition, independent of Aβ-PET. Results: Adjusting for tau-PET, the quadratic effect of WMH interacted with Aβ-PET to impact memory. There was no interaction between either the linear or quadratic effect of WMH and Aβ-PET on executive function. There was no interaction between WMH volume and tau-PET on either cognitive measure. Conclusion: Results suggest that cerebrovascular lesions act synergistically with Aβ to affect memory, independent of tau, highlighting the importance of incorporating vascular pathology into biomarker assessment of AD.

Background: Posterior cortical atrophy (PCA) and logopenic progressive aphasia (LPA) are associated with characteristic patterns of structural network degeneration. Little is known about longitudinal patterns of white matter tract degeneration in these phenotypes. Objective: To assess longitudinal patterns of white matter degeneration and identify phenotype specific cross-sectional and longitudinal diffusion tensor imaging (DTI) biomarkers in PCA and LPA. Methods: Twenty-five PCA, 22 LPA and 25 cognitively unimpaired (CU) individuals were recruited and underwent structural MRI that included a DTI sequence with a follow-up one year later. Cross-sectional and longitudinal mixed effects models were fit to assess the effects of diagnosis on baseline and annualized change in regional DTI metrics. Discriminatory power was investigated using the area under the receiver operating characteristic curves (AUROC). Results: PCA and LPA showed overlapping white matter degeneration profiles predominantly in the left occipital and temporal lobes, the posterior thalamic radiation and sagittal stratum at baseline, as well as the parietal lobe longitudinally. PCA showed degeneration in the occipital and parietal white matter, cross-sectionally and longitudinally, compared to CU, while LPA showed greater degeneration in the temporal and inferior parietal white matter and the inferior fronto-occipital fasciculus cross-sectionally, and in parietal white matter longitudinally compared to CU. Cross-sectionally, integrity of the inferior occipital white matter was best able to differentiate PCA from LPA, with an AUROC of 0.82. Conclusion: These findings contribute to our understanding of white matter degeneration and support usage of DTI as a useful additional diagnostic biomarker for PCA and LPA.
