¿Una ‘nueva narrativa’? Tres representaciones contemporáneas de la literatura latinoamericana: Jorge Volpi, Martín Rejtman y Rodrigo Fresán
Authors: Fernández Polo Sara , Mateo Jiménez Martina , Sánchez Martínez Francisca 
Published: July 2023

A partir de las propuestas de Jorge Volpi, Martín Rejtman y Rodrigo Fresán, autores latinoamericanos nacidos en la década de los sesenta, intentaremos dar cuenta de cómo esta narrativa enfrenta un cambio de paradigma resultado de los procesos contemporáneos marcados por la globalización. Ello se traduce en la exploración de una identidad desprendida ahora de lo local y en la configuración de unos personajes determinados por la inercia. En definitiva, estéticas que confluyen en la búsqueda de nuevas perspectivas con que enfrentar lo latinoamericano.Palabras clave: narrativa latinoamericana, globalización, Jorge Volpi, Martín Rejtman, Rodrigo Fresán.A new narrative? Three exponents of contemporary Latin American literature: Jorge Volpi, Martin Rejtman and Rodrigo FresánAbstract: In this article we analyze the fiction of Jorge Volpi, Martín Rejtman and Rodrigo Fresán, Hispano-American writers born in the sixties. We focus on how this narrative undergoes a change of paradigm as a result of contemporary dynamics affected by Globalization. This literature explores an identity emerging from the loss of the «local» concerns (contradictory to «global»), as well as develops characters determined by inertia. In short, the aesthetics converge in search of new perspectives to confront Latin American issues.Key words: Latin American narrative, globalization, Jorge Volpi, Martín Rejtman, Rodrigo Fresán.
2020 Parliamentary Elections in Online News Dailies: Do the Media Tend to Criticize the Ruling Party More
Authors: Danieliūtė Iveta 
Published: July 2023

Voters tend to criticise and punish the ruling party for mistakes made during the term of office and therefore never vote for the same party twice in a row. However, there are no studies on whether the ruling party receives more criticism in the media during election periods.
The article focuses on the portrayal of the opposing political parties – the Lithuanian Peasant and Green Union and the Homeland Union – Lithuanian Christian Democrats – in online news dailies during the 2020 parliamentary elections.
The study shows that the media publishes more negative news about the ruling party, but that the communication strategy chosen by the politicians themselves also contributes to this. A link can also be found between the presentation of parties in the media and the final results of the parliamentary elections.
Powwow Regalia in Identity Performance and Authentication
Authors: Cselényi Zsuzsanna 
Published: July 2023

AbstractThrough personal narratives of powwow involvement and motivation for dancing, this essay examines the ways in which regional and personal identities are being formed, adjusted, negotiated, and expressed through dance regalia at powwows in the Midwestern United States. Dancers use clothes as an explicit marker of their Native identity and powwows as a justifying context for their ideologies of authenticity. Powwow involvement is also used to consolidate, reclaim, craft, revive, and create an identity that authenticates one's place in the powwow community in which internal and external roles and rules reinforce each other. Giving voice to different constituents at Midwestern powwows, from Natives to non-Native enthusiasts, the study explores the factors that influence the bases and strategies of such authentication, as well as the rhetoric by which these ideologies are expressed.
“The Sisters of the Redeemer in the Trauma of Dispersion”. •
Authors: Paréj-Farkas Katalin 
Published: July 2023

AbstractWhile researching the history of the Sisters of the Divine Redeemer, also referred to as the Sisters of the Redeemer, it became clear that the ordeals of the Second World War and the Communist dictatorship had a profound impact on the congregation, which was engaged in nursing and teaching. The sources allow us to reconstruct the horrors of the advancing battlefront and the sisters' flight, along with their determination to provide social assistance and their role in saving Jews. The Communist regime that emerged after the war forced the congregation into an increasingly impossible situation, depriving them of their teaching positions and nursing vocation. Their internment in 1950 and the revocation of the congregation's operating license seemed to have eliminated the community entirely. However, recollections of the events of the 1950s and 1960s, together with state security reports, attest that the congregation survived in the form of a “subterranean stream,” and that tiny communities of sisters continued to pursue their monastic vocation, often in a single apartment that functioned as a mini convent. The traumas they had experienced rarely crushed the sisters' inner sense of peace, and they strove to cope with the harassments inflicted by the party-state by adapting to the new situation.
Implementation of clustering technique for analyzing consumer buying behavior during the COVID-19 pandemic: a case in the beauty industry
Authors: Achsan Beny Maulana , Hidayanto Achmad Nizar 
Published: July 2023

The global demand for beauty products continues to grow due to raised public awareness of applying cosmetics, with a 1.45 % to 3.34 % growth annually. Unfortunately, the COVID-19 outbreak broke out globally in December 2019, affecting face-to-face businesses such as the beauty industry falling until –7.11 % in 2020. This study aims to analyze the impact of the COVID-19 outbreak on Indonesia’s beauty industry and the shift in the beauty consumer segment during the pandemic.
This study adopts the react-cope-adapt (RCA) framework to construct the COVID-19 pandemic periodization in Indonesia. The correlation analysis was used to investigate the impact of the COVID-19 pandemic on the beauty industry. In addition, clustering techniques were employed to identify hidden consumer segments and product preferences throughout the COVID-19 outbreak.
The study shows that COVID-19 cases positively impact beauty company’s sales during the reacting phase. A strong negative relationship between COVID-19 and company revenue was observed in the coping phase. In the adapt phase, the negative impact of COVID-19 on the company’s sales has decreased. Our finding also confirms the shift in consumer buying behavior during the pandemic. Consumers prefer to buy cosmetics products online than offline during the reaction phase. In the coping phase, consumers slowly begin to purchase in-store. Finally, consumers return to buying cosmetics offline in the adapting phase, similar to before the pandemic. The clustering results showed three hidden consumer segments: the loyal consumer segment, the impulsive consumer segment, and the compulsive consumer segment. In addition, during the pandemic, consumers prefer to buy skincare products over make-up products since government policies forced people to stay, work, and study at home.
Our study has theoretical and practical implications. Theoretically, our results support the usefulness of the RCA model and clustering techniques in analyzing the change in consumer buying behavior during a time of crisis, such COVID-19 pandemic. Practically, beauty industries can anticipate this shift by accelerating the digital business transformation and focusing on the most preferred product to sustain their business

Some archipelagic countries must have wide sea. This condition means that there is transportation of goods and people problem. Therefore, an effort has been made to explore renewable energy especially solar energy. In this research, a BLDC (Brush Less Direct Current) motor propeller is applied, and PID-N (Proportional, Integral, and Derivative – Filter Coefficient) method for Catamaran ship speed control. Where PID-N has additional filters such as P, I, and D; however, the advanced performance of this control uses RLS (Recursive Least Square) actuator modeling is the most systematical and flexible design. The experiment includes the speed response of ships with payload and without payload, as well as changes in speed settings. The results show that the ship's speed control using the PID-N has smooth and definite speed control. The PID-N design is systematical, easy and quick for the control designer to change the actuator or sensor performance, if there will be any actuator or sensor replacement with different specifications, which is required in commercial. As it is known, in commercial design, time and method are crucial and has to be effective. The PID-N control method shows its superiority. In detail, the Catamaran speed setting is incremented from 0.4 m/s to 0.6 m/s without payload, the average settling time is 6 seconds with the average error speed 0.071 m/s in the set speed 0.6 m/s. For setting speed increased by 0.4 m/s to 0.6 m/s with payload, settling time gets longer, 7 to 13 seconds with the average error speed 0.01 m/s in the set speed 0.06 m/s. It performs small errors and fasts settling time. The ship model has experimented on an artificial pond, it is related to the proportional small sea wave. The research also shown the ratio of electric power consume toward speed setting is in exponential formula

The object of the study is bread made from medium rye flour enriched with rowan powder. The study is devoted to the formation of quality and increase of the shelf life of bread. The technology of obtaining powder from Sorbus aucuparia involves freezing fruits, preliminary dehydration by osmotic dehydration, drying and grinding. It was found that rowan powder contains the highest amount of potassium (860 mg/100 g) and 6.7 % crude fiber. Rowan powder contains 1.72 mg/100 g of vitamin C, which gives it antioxidant properties. The experimental samples of bread from medium rye flour were made by the liquid sponge method. Rowan powder was added to samples D1, D2, and D3 in an amount of 5, 10, and 15 %, respectively. The control sample (C) was made according to a standard recipe. The analysis of the physicochemical parameters of bread quality showed that with an increase in the amount of rowan powder added, the acidity of the samples increased, but did not exceed the standard values. Rowan powder did not significantly affect the moisture content of the bread crumb. With the addition of 5 and 15 % powders, the moisture content was 46.7 and 46.6 %, respectively. In sample D2, which contained 10 % rowan powder, the moisture content was the lowest – 45.9 %. The effect of rowan powders on the storage ability of rye flour bread was investigated. It was found that mold appeared on the surface of sample C on the 5th day of storage. In the sample with a rowan powder content of 5 % – on the 12th day of storage, with a powder content of 10 % – on the 21st day of storage. On sample D3, mold was observed on the 16th day of storage. These results indicate that rowan powder can be used as a natural preservative that can significantly increase the shelf life of rye flour bread

The object of research is the innovative activity of organizations. Papers that consider the assessment of the benefits of Ukraine's accession to the European Union (EU) ignore innovation activity in the context of acquiring competence for the integration of organizations into the European space. This predetermined the study to assess the state and prerequisites for effective innovation activity of Ukrainian organizations. An uneven concentration of innovative organizations by types of economic activity has been determined, which is explained by imperfect mechanisms for regulating regional development. The negative dynamics of the science intensity of the gross domestic product (GDP) of Ukraine (by 0.32 %), its lowest level among the EU countries (0.99 %) were noted. This makes it impossible to compete with supplier countries of new technologies and products with a high degree of added value. A reduction in the cost of fundamental research and the number of innovative organizations (by 72.09 %), a decrease in the number of employees engaged in scientific research was identified. The smallest amounts of funding for employee training in accordance with EU requirements have been determined, which reduces the competitiveness of the economy.
A distinctive feature of the study is its standpoint of the influence of indicators on the formation of conditions for the acquisition of competence by organizations in the European market. This means the technological renewal of production, intensification of research into the latest areas of science, achievement of intellectual leadership, reorientation of finance to investment in human capital. The results are useful for executives who, on the way to joining the European space, seek to successfully overcome the barriers of the world's largest market owing to organizational competence

The object of research is the process of using a hydrogen fuel cell to generate and accumulate electricity. The study highlights the feasibility of using a hydrogen fuel cell to provide electrical load.
The potential of using hydrogen as an alternative energy source was evaluated. SWOT analysis was used as a research method, based on the results of which recommendations were developed. The proposed measures could be taken to increase the use of hydrogen energy as an alternative to traditional energy sources.
The use of hydrogen technologies in an administrative building connected to an existing electrical network was analyzed.
The economic and environmental aspects of the use of hydrogen fuel cells to meet the demand for electrical load were investigated. Six schemes of energy supply of the building and comparing them to select the optimal solution have been developed. In the study, the assessment tool was the Hybrid Optimization of Multiple Energy Resources (HOMER) software.
The considered schemes were evaluated in accordance with a single generalized indicator. As a result, it was determined that the use of a hydrogen fuel cell could increase the efficiency of the traditional system by 85 %. For renewable energy systems, there was an increase in efficiency of 7 % (for the wind generator) and 10 % (for the photocell).
The practical use of the results will contribute to the efficiency of the process of electricity production by equalizing the stability of energy supply in hybrid systems. The economic and environmental assessment conducted demonstrates the prospects of using a hydrogen fuel cell. This assessment is designed to strengthen consumer confidence in the use of hydrogen fuel cells and hydrogen in general

Published: July 2023

Deep learning algorithms rely on digital pathology to classify tissue tumors, where the whole tissue slides are digitized and imaged. The produced multi-resolution whole slide images (MWSIs) are with high resolution that may range from about 100,000 to 200,000 pixels. MWSIs are often stored in a multi-resolution configuration to simplify the processing of images, navigation, and efficient exposition. This work develops a network for classifying MWSIs that require high memory employing a deep neural Inception-v3 architecture. This work employs the MWSIs from Camelyon16, which is around 451 GB in size of Challenge dataset from two independent sources including 400 MWSIs as a total of lymph nodes. The training dataset contains 111 MWSIs of tumor tissue and lymph nodes and 159 WSIs of normal lymph nodes. The developed model uses sample-based processing to train extensive MWSIs employing the MATLAB platform. The model introduces transfer learning techniques with an Inception-v3-based architecture to categorize separate samples as a tumor or normal. Therefore, the main aim here is to achieve two-classes binary segmentation containing normal and tumor. This includes creating a new fully connected layer for the Inception-v3 architecture with two classes and compensating new layers instead of the original final fully-connected layers. The results obtained demonstrated that the heatmap visualization can recognize the boundary coordinates of ground truth as sketchy Region Of Interest (ROI), where the green boundary represents the normal regions and the tumor area with red boundaries. The proposed Inception v3 Convolutional Neural Network (CNN) architecture can achieve more than 92.8 % accuracy for such MWSIs dataset to categorize brain tumors into normal and tumor tissue

Published: July 2023

This paper proposes a method that makes it possible to study the patterns of changes in the concrete strength of reinforced concrete crossbars depending on the heating temperature under fire conditions by interpreting the results of their standard fire tests. For the implementation of this method, it is proposed to use similar data obtained using mathematical modeling based on the finite element method and given material properties, including the curve of concrete strength reduction recommended by the guidelines, as data included in the set of measurement results during fire tests depending on temperature. Such data are time dependences of temperature indicators at individual cross-section points and time dependence of the maximum deflection of the crossbar. The article proposes an interpolation method that makes it possible to set the temperature at any point of the section based on the approximation of the isotherms by parabolas with a variable indicator of their power. A method based on the mathematical interpretation of temperature indicators obtained using the proposed interpolation method and the curve of the dependence of the maximum deflection on time using a deformation model for describing the stress-strain state is proposed to identify the dependence of the concrete strength of reinforced concrete crossbars.
The work also shows that the results obtained using the proposed method of identifying concrete strength reduction coefficients are adequate as their relative error is on average no more than 7 %. Based on the results, the possibility of its application to study the regularities of the decrease in the strength of reinforced concrete crossbars under fire conditions has been proven
Improving the technology for ensuring the magnetic cleanliness of small spacecraft
Authors: Getman Andriy 
Published: July 2023

The object of this study is the technology of ensuring magnetic cleanliness when applied to small spacecraft (SC) with overall dimensions of ~1 m in terms of minimizing the effect of magnetic interference on the on-board magnetometer. As part of solving the general problem of increasing the reliability of spacecraft, the task of improving the technology of magnetic cleanliness is considered. It is shown that the use of the multi-dipole model for the calculation of ~50 nT magnetic interference is limited in the design of small space vehicles that have an increased installation density. The expediency of using a model of its spherical harmonics instead of a multi-dipole model to represent the magnetic field of satellite components was theoretically justified. For the practical application of the model, the budgeting of the projections of the magnetic induction of hindrance to the onboard magnetometer according to the experimentally determined coefficients of the dipole, quadrupole and octupole spherical harmonics is proposed. An algorithm for calculating the coordinates of the location and projections of the magnetic moment of the dipole source inside the satellite based on the results of measuring the coefficients of spherical harmonics of its components is proposed. The possibility of representing the coefficients of the spherical harmonics of the magnetic field of the entire satellite in the form of the sum of the listed corresponding coefficients obtained during field measurements of the components is theoretically justified. It is proposed to use the difference between the calculated and measured values of the corresponding coefficients as a criterion for the quality of the work to ensure magnetic cleanliness. If the proposed procedure is used in the space industry, the quality of ensuring the magnetic cleanliness of small space vehicles can be increased, thereby improving the reliability of their operation in orbit
Influence of the monomer form of orthosilicic acid on the stability of polyalumosilicon coagulants and their efficiency in the treatment of drinking water
Authors: Mandryka Artem , Pasenko Oleksandr , Vereschak Viktor , Osokin Yevhen 
Published: July 2023

The object of the study was polymeric alumino-silicon coagulants modified with the monomeric form of orthosilicate acid. The methods and precursors for obtaining stable solutions of composite alumino-silicon coagulants, as well as the effectiveness of coagulation treatment of a surface source of drinking water, were considered. The samples were obtained in two ways:
1) partial hydrolysis of medium-basic aluminum polyhydroxychloride together with sodium silicate solution (PolyAKKg);
2) mixing highly basic aluminum polyhydroxychloride together with a ready solution of orthosilicic acid with a high (above 50 %) monomer content (PolyAKKz).
In the course of research, the problem of the short shelf life of composite alumino-silicon coagulants was solved, which had prevented their industrial implementation in drinking water preparation processes.
It was established that the resulting composite coagulants had the following parameters: Al2O3, 8.075–8.725 %; SiO2, 0.058–0.725 %; Al/Si ratio, 20–250; basicity, 41.4–80.7 %. The effectiveness of the obtained composite coagulant and commercial coagulant was tested under laboratory conditions at a surface source of drinking water by reducing turbidity and by the concentration of residual aluminum in the water after coagulation. The results showed that composite coagulants of the PolyAKKz type with the addition of orthosilicic acid with a high monomer content (above 50 %) obtained using methanesulfonic acid hydrolysis as a precursor have higher solution stability compared to other precursors or coagulants of the PolyAKKg type.
The study results could be used to design new composite coagulants for the preparation of drinking water from surface sources with high turbidity
