Efficient and Site-Specific C–H Hydroxylation of Enones via a New Mechanism Useful for the Late-Stage Functionalization of Drugs and Natural Products
Authors: Zheng Cheng-Yu , Yue Jian-Min
Published: July 2022

A mild and efficient method for the direct C(sp3)–H hydroxylation of enones in a site-specific way was developed via visible-light-induced hydrogen-atom transfer (HAT), which facilitates -hydroxylation of primary, secondary, and tertiary C–H bonds of different enones without involving metal and peroxide. The mechanistic study showed a new catalytic view, where Na2-eosin Y served as both the photocatalyst and the source of catalytic bromine radical species in the HAT-based catalytic cycle, and finally sacrificed itself completely by oxidative degradation to produce bromine radical and a major product phthalic anhydride in an environmentally friendly way. This scalable method was demonstrated by plenty of substrates to be extremely useful for the late-stage functionalization of drugs and natural products, and, in particular, has potential application in industry for large-scale production.
How very small changes in the peptide sequence of β-amyloids influence their redox properties. Electrochemical studies of copper complexes with Aβ(11-16) and pAβ(11-16)
Authors: Wiloch Magdalena Zofia , Jönsson-Niedziółka Martin
Published: July 2022

Here we demonstrate a significant difference in redox behaviour of copper complexes with β-amyloids Aβ(11-x) and pAβ(11-x) which are models for important components of senile plaques. A small change in the peptide chain may enhance reactive oxygen species (ROS) formation which can severely damage nerve cells.

Ubiquilin-2 (UBQLN2) is a ubiquitin-binding protein that shuttles ubiquitinated proteins to proteasomal and autophagic degradation. UBQLN2 mutations are genetically linked to the neurodegenerative disorders amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD). However, it remains elusive how UBQLN2 mutations cause ALS/FTD. Here, we systematically examined proteomic and transcriptomic changes in patient-derived lymphoblasts and CRISPR/Cas9–engineered HeLa cells carrying ALS/FTD UBQLN2 mutations. This analysis revealed a strong up-regulation of the microtubule-associated protein 1B (MAP1B) which was also observed in UBQLN2 knockout cells and primary rodent neurons depleted of UBQLN2, suggesting that a UBQLN2 loss-of-function mechanism is responsible for the elevated MAP1B levels. Consistent with MAP1B’s role in microtubule binding, we detected an increase in total and acetylated tubulin. Furthermore, we uncovered that UBQLN2 mutations result in decreased phosphorylation of MAP1B and of the ALS/FTD–linked fused in sarcoma (FUS) protein at S439 which is critical for regulating FUS-RNA binding and MAP1B protein abundance. Together, our findings point to a deregulated UBQLN2-FUS-MAP1B axis that may link protein homeostasis, RNA metabolism, and cytoskeleton dynamics, three molecular pathomechanisms of ALS/FTD.

The impact of the Covid-19 pandemic has had a far-reaching effect on higher education institutions, and individual student assessments have garnered much attention during the pandemic. This study aimed to validate Science, Technology, Engineering, and Mathematics (STEM) application instruments using the Rasch analysis employing Winsteps version 3.73. A survey was conducted with 201 respondents from two provinces in Indonesia. The students were selected by convenience sampling and answered the adopted STEM application instrument. The STEM application instruments were adapted, and these were divided into seven sub-constructs derived from STEM disciplines. Rasch Modelling was employed for data analysis using Winsteps version 3.7.3 to analyse reliability, separation, item fit statistics, unidimensionality, and rating scale calibration. Each sub-construct fulfilled a minimum of 0.65 for Cronbach alpha, item, and person reliability, and most of them had more than 1.5 person and item separation. In general, each item had a good score of the mean square, Z-tolerated standard, and point measure correlation, indicating fulfilment of the Rasch measurement model. The analysis also showed unidimensionality assumption and an excellent rating scale. This study contributed to the body of STEM knowledge by using Rasch Modelling to test the validity and reliability of STEM application instruments.

The extent of monkeypox virus environmental contamination of surfaces is unclear. We examined surfaces in rooms occupied by two monkeypox patients on their fourth hospitalisation day. Contamination with up to 105 viral copies/cm2 on inanimate surfaces was estimated by PCR and the virus was successfully isolated from surfaces with more than 106 copies. These data highlight the importance of strict adherence of hospital staff to recommended protective measures. If appropriate, pre-exposure or early post-exposure vaccination should be considered for individuals at risk.
Historian as a public intellectual: media discourse about Timothy Snyder’s works on Ukrainian topics
Authors: Stelmakh Marta
Published: July 2022

In the article, the author analyses the media discourse around the works of Timothy Snyder, one of the leading experts on the history of Eastern Europe. The relevance of the topic is that T. Snyder’s materials and interviews on Russian-Ukrainian relations are often used and analyzed by both Ukrainian and foreign media. The current Russian-Ukrainian war has escalated, and the changes in the views of the scholars’ critics are worth mentioning. The subject of the study is a criticism of Timothy Snyder’s views on Ukrainian issues. The aim is to outline the discourse around the author’s works and identify his criticism’s main tendencies. The following methods were used in the process of scientific research: comparative, historical, systems analysis, content analysis, and others. The novelty was a comparative analysis of criticism of the works of Timothy Snyder before and after the Russian invasion. As a result of the study, the criticism of Timothy Snyder’s monograph “Bloodlands: Europe between Hitler and Stalin”, his texts on the past of Ukrainian society and the historical context of Russian-Ukrainian relations, as well as criticism of world politics and his predictions of declining democracy were reviewed. Timothy Snyder is mentioned as both the best interpreter of the twentieth century and an alarmist who unjustifiably emphasizes the disappearance of freedom and ignoring of history. The main tendencies in the criticism of the researcher were singled out: overly emotionally colored speech, dubious methodology, and obsession with statistics in the monograph. Critics of the works on the Russian-Ukrainian war had accused the author of distorting facts. The comparison of Vladimir Putin to both Adolf Hitler and Joseph Stalin was believed to be unjustified, and allegations of Putin’s regime as fascist were considered inappropriate. At the same time, a large number of public intellectuals note his contribution to the discovery of significant problems in the history of Eastern Europe — less studied compared to other regions. Today, the scholar continues to draw the world’s attention to Ukraine’s past, and its ties with Europe and stands guard over freedom and democracy. Given this, there is a need for further study of both Snyder’s works and criticism of his views.
The image of an elderly woman in media narratives during the Russian-Ukrainian war
Authors: Babenko Vatalii
Published: July 2022

The article is dedicated to the functioning of the images of a senior woman in the communicational space of mass media and Internet memes as concepts that have formed under the influence of the events of the Russo-Ukrainian war after February 24, 2022.

The subject of the research is actualized in the context of changes in gender role stereotypes in the course of the establishment of the legal society, strategies of information warfare, and ideological propaganda, which is meant to influence the international image of Ukraine. The aim of the study is to analyze the media image of an elderly woman, taking into account such concepts as “informational warfare”, “propaganda”, “stereotype”, and “archetype”, because it is through them that the influence on the mass consciousness is performed, in particular, values are established, worldview models are normalized, humanization processes are legitimized.

Thanks to the use of analysis, generalization, and interpretation methods, we have managed to systematize the image of a senior woman as an active mass media message. As the results of our research, we have clarified the difference between the narratives in the image of a senior woman that forms Ukrainian and Russian informational environments. We have identified the communicational goal with which they are being spread. Also, we have determined the difference in the mechanics of popularization of the symbolic figure of a senior woman in the mass communication means.

The novelty of the research lies in the analysis of the informational processes in the modern history of Ukraine, which are currently in the state of dynamic evolution. Also, the novelty is conditioned by the cross-disciplinary vision, which takes into account the experience of the gerontology and memetics, the most modern approaches for the Ukrainian scientific thought.

Prospects of further research lie in several directions. Among the scientific investigations that rest upon the symbolic codes of physicality in the communicative field there are: analysis of the development of gender-based and age-based stereotypes in Ukrainian mass media; determination of proactivity of archetypical images as a tool used for the creation of informational defense; further comparison of the roles archetypes play in mass media of legal and totalitarian states; identification of the role markers of physicality play in the set of communicational tools used by information warfare.
Discussion aspects of interdisciplinary interaction of journalism and oral history
Authors: Hudoshnyk Oksana , Temchenko Liliia
Published: July 2022

The article presents the context of modern scientific debates on the boundaries of interdisciplinarity. The subject of the study is the common procedure of the use of oral history practices in the mass media space. The oral history itself is changing rapidly under the pressure of digital platforms such as StoryCorps (USA), Listening Project (UK), The Story Project (Australia), and The Tale of a Town (Canada). Another key thing is the fact that the changes affected not only the technological process of archiving and dissemination of information but also the basic foundations of oral history, which is its methodology. The in-depth interview is replaced by the “rapid response collecting” method and historical storytelling. The purpose of the article is to outline the discussion field of the modern scientific discourse of the problem, to present the most significant interdisciplinary interaction using the example of world and Ukrainian media, namely: coverage of contradictory and ambiguous interpretations of historical facts; narrative; prolonged communication; multimedia and multiplatform. The research methods are traditional empirical methods of observation and description, as well as paradigmatic analysis of the functional features of oral history practices in journalism.

Results of the research. Basic characterological directions proposed in the study allowed us to present the main points of discussion in various aspects: the use of oral historical materials, especially “hidden history” through the eyes of eyewitnesses, become an additional source of journalistic clarifications, investigations and expansion of the information agenda; addressing marginal themes of history, giving a voice to terrorist groups and participants in genocides poses extremely complex and ethically controversial questions to the audience; multimedia and multiplatform give new life to oral history information, while performance, theatre and participation are added to the usual practices of new media. The most expressive manifestation of changes in this interdisciplinary discourse is the practice of digital storytelling; its media use is illustrated by the BBC’s Capture Wales digital storytelling project.

As part of the scientific discussion that has continued for the last few years, the issues of democratization of history, mass inclusion in digital archives, the creation of powerful social projects, and attempts to distance oral history as a separate discipline have been actualized. Moreover, it is recognized that, like any creative practice, interdisciplinarity remains a wide field for experimentation and creativity.
“RISE UP, UKRAINE! A LIGHT OF TRUTH WILL SHINE, AND SLAVE CHILDREN WILL PRAY IN FREEDOM”: THE EMBROIDERED FOLKLORIZED WORKS BY TARAS SHEVCHENKO
Authors: Brovarets Tetiana
Published: July 2022

The article is devoted to the phenomenon of embroidering the folklorized poetic works by Taras Shevchenko on the towels (rushnyky), many of which belong to the patriotic inscriptions (for the most part, Western Ukraine, the 1930s). These folklorized lines could be in a variety of contaminations. Embroideresses often combined between two and four different works, therefore creating an absolutely new text. Particularly, I demonstrate rushnyky with the embroidered verbal formula “Rise up, Ukraine! A light of truth will shine, and slave children will pray in freedom” (the prototext is the mystery “Big Cellar”) which in different cases is combined with other verbal formulas (which are also folklorized works by Kobzar): for example, “Love each other, my brothers, love Ukraine, and pray to God for our unfortunate country” (the prototext is the poetry “Remember, My Brothers” from the cycle “In the Casemate” by Taras Shevchenko) or “Love your Ukraine. Love her… in the difficult time, in the last worst moment pray to God for her” (the prototext is the 12th poetry “Will We Get Together Again?” from the cycle “In the Casemate” by Taras Shevchenko). The concrete cases (on the example of the poetry “My Testament” by T. Shevchenko) where a political content is closely intertwined with a private sphere and glorification of the poet have been also analyzed. It is shown that at the beginning of the 21st century there was re-actualization of the epigraphic embroidery samples which had been embroidered at the first half of the 20th century. Such cases can be well traced on social networks, when, during revolutionary events, photographs of epigraphic towels are published, in particular with embroidered lines which are folklorized works by Taras Shevchenko. A case of double re-actualization of the same sample of epigraphic embroidery was also recorded (the rushnyk with the verbal formulas “Arise, Ukraine! pray to the Lord for her “Rise up, Ukraine! A light of truth will shine, and slave children will pray in freedom” and “Love your Ukraine. Love her… in the difficult time, in the last worst moment pray to God for her”) with a time interval of nine years (during the Orange Revolution and the Revolution of Dignity).
HANDWRITTEN EPIC WORK OF THE EARLY VYACHESLAV MEDVID’ (1970s)
Authors: Vas’kiv Mykola
Published: July 2022

The article analyzes epic works (fragments, sketches, stories, the shot novel “Completely Military Maneuvers”), as well as the play “Bomb, or Responsible Person” of the early stage of creativity (1970s) Shevchenko Prize winner Vyacheslav Medvid’ (Born in 1951), which were not published for various reasons and remained in the manuscripts of the writer and therefore remained out of the attention of researchers. This works fit into the context of the writer’s biography, his work as a librarian in Uzhhorod, service in the army, moving to Boyzrka and Kyiv, in the context of intellectual and cultural communication. Some of the manuscripts are impressionistic reflections of the surrounding world and their own perception of this world, which are very close in genre to “sketches”, “drawings”, samples” of the late nineteenth – early twentieth centuries. Also through most works is the motive of determining their own path, choosing a writing profession. An analysis of V. Medvid’s unpublishes works of the 1970s gives grounds to assert that from text to text the author’s narrative skill grew, a range of problems, methods of imagery, stylistic features, and chronotope were developed, which would later form the basis of the writer’s idiosyncrasy. V. Medvid’s manuscripts, which preserve further author’s corrections and edits, make it possible to trace the formation of idiosyncrasies, a critical attitude to written texts, and persistent purposeful activity to improve them. Most often, the corrections were reduced to the removal of unnecessary, according to the writer, segments of the text, especially close to journalistic interpretive self-explanations. To a large extent, this correlates with the desire to write in accordance with the technique of “iceberg”, which testified to the great interest of V. Medvid’ in the work of E. Hemingway, V. Faulkner and others. The short play is written in the vein of absurdist drama, which was little known and not tolerated in the USSR. The writer did not make serious attempts to publish the manuscripts in the decades, believing that they had not yet reached the proper level of skill.
RESPONSIBILITY AND VOCATION AS A LIFE STRATEGY (ON THE EPISTOLARIUM OF LESYA UKRAINKA)
Authors: Virchenko Tetiana
Published: July 2022

The research belongs to those studies in which a successful attempt was made to investigate the moral foundations of Lesya Ukrainka's life strategy. The epistolary heritage was chosen as the object, as it is a grateful material for the study of the author as a real person without the admixture of interpretations of the recipients. A similar study is on time also because Lesya Ukrainka's published letters without Soviet banknotes are involved.

Anthropological literary studies has been chosen as the main literary approach. This vector of exploration was determined by the reasoning of the well-known forester L. Skupeyko, who noted that modern science needs research on the concept of the author's personality. The study of the state of development of the problem has shown that science has occasional concluding statements, but there is no intelligence that would be the basis for such a study.

Working with epistolary required special objectivity. M. Kotsyubynska's warnings about such treatment of letters were identified as the basis and important for compliance. To outline the content of the concepts of "responsibility" and "vocation" was chosen the latest study E. Mulyachuk. Thus, in order to determine one's own mission - life strategy - it is extremely important to be aware of one's own self-determination, to be ready to resist everyday life, and to give preference to the interests of others.

Lesia Ukrainka's epistolary legacy gives grounds to say that it is important for a writer to have the inner strength to overcome her own misfortune in order to realize her own life strategy. This will help to overcome the fear of living. In addition, the awareness of the professional vocation must be in harmony with life goals. According to Lesia Ukrainka, the professional mission should be realized through a number of specific actions: publishing translations, forming a library, etc. In the future, it is advisable to continue the study of epistolary heritage, as well as to study the life strategies of the main characters of the writer's works. In this way, we will approach the creation of the concept of the personality of Lesya Ukrainka's work.

Published: July 2022

The purpose of this study is to implement the ensemble self-organizing maps (E-SOM) method to impute missing values at the preprocessing data stage, which is an important stage when making predictions or classifications. The Ensemble Self-Organizing Maps (E-SOM) is the development of the SOM imputation method, in which the E-SOM method is implemented by applying an ensemble framework using several SOMs to improve generalization capabilities. In this study, the E-SOM imputation method is implemented in South African heart disease data using random forest as a classification model. The results of the model evaluation showed that for accuracy in testing data, the Random Forest model formed from E-SOM imputed data yields better accuracy values than the Random Forest model formed from SOM-imputed data for variations of 36, 49, 64, and 81 neurons, while for variation of 25 neurons both models produce the same accuracy value. From the variation of the number of ensembles applied, the E-SOM imputation method with a combination of 81 neurons and 15 ensemble numbers produced a Random Forest model with the most optimal value of accuracy.

Change in water activity of some Turkish hazelnut cultivars at different moistures and temperatures
Authors: KOÇ GÜLER Saadet
Published: July 2022

Objective: Observation of the changes in water activity values of some Turkish hazelnut cultivars at different moisture levels (ML) at varying ambient temperatures. Thus, especially in hazelnut storage and transfer processes, regulations regarding the protection of the quality of the product under changing humidity and temperature conditions are foreseen. Materials and Methods: In this study, water activity (aw) of Tombul, Palaz, Çakıldak and Kalınkara hazelnuts were determined at different ML (2, 4, 6, 8, 9 and 12%) and different temperatures (20, 21, 22, 23, 24, 25, 26, 27, 28, 29 and 30°C). Regression equations were generated to estimate aw values of hazelnuts with a known moisture at different ambient temperatures.  Results: Considering the entire temperatures, it was observed that a unit (1%) increase in moisture yielded 0.055 - 0.062 unit increases in Çakıldak cultivar, 0.052 - 0.055 unit increases in Palaz cultivar, 0.047 - 0.050 unit increases in Tombul cultivar and 0.047 - 0.048 unit increases in Kalınkara cultivar. Different aw values were observed at the same ML of the cultivars and generally the aw values were tended to increase with increasing temperatures. Conclusion: It was concluded that water activity influenced several quality parameters (color, lipid oxidation and etc.). Present findings revealed that hazelnut cultivars with the same moisture levels might have different water activity values. The fact that the varieties at the same ML have different water activity values indicates that it will be more objective to use the water activity value in storage or shelf life studies. In the calculations made using the obtained formula, it was seen that Palaz and Kalınkara (at the same ML) cultivars had higher aw values than the other two cultivars. For this reason, it is thought that storing Palaz and Kalınkara separately from Tombul and Çakıldak cultivars may reduce the possible risks.
Meningkatkan Perkecambahan Biji Kelor (Moringa oleifera Lam.) Tersimpan Menggunakan Asam Giberelat
Authors: Santoso Bambang Budi
Published: July 2022

Gibberelin (Gibberellic acid) is a plant hormone that is responsible for the seed germination process. Germination is the process by which an inactive embryo grows and eventually forms a seedling and subsequently produces a seedling. A total of 50 seeds of Moringa (Moringa oleifera Lam.) which have been stored for 12 months and 24 months were soaked in different concentrations of Gibberellin solution (0 mg/L; 2.5 mg/L, 5.0 mg/L, 7.5 mg/L, dan 10.0 mg/L) for 24 hours and then sown in a bath soil-sand-husk charcoal (1:1:1 v/v) germination. Since 10 days after planting the seeds, observations and calculations were made on the number of seeds that germinated, the number of abnormal germinations, and the number of days when 50 percent of the seeds germinated. The results showed that the number of seeds and the speed of seed germination were proportional to the concentration of Gibberellins. Seeds treated with high concentration of Gibberellin (9 mg/L) had the highest number of germination seeds compared to seeds with lower concentration of Gibberellin. Without giving Gibberellins from the outside, Moringa seeds that have been worn out (stored 1-2 years) were not able to germinate properly.
Collective Narratives of the Kfarsghabi Diasporic Community: An Important Tool to Reinstate Group Solidarity, Ethnic Identity and Societal Acceptance
Authors: Karner Marie Johanna
Published: July 2022

This paper explores the significance of collective narratives for a particular diasporic community. The analysis demonstrates that addressing narratives is important not only to ensure understanding between old and new members, but also to expand societal acceptance and provide adequate formal assistance to sub-ethnic communities. The Kfarsghab community, whose members identify with a Maronite village in the Wadi Qadisha (Holy Valley) in Lebanon, is a suitable case study, especially due to the high commitment of certain members who disseminate information and stories. I analyzed digital platforms, searched in archives, and conducted qualitative interviews with community members in five countries. Using a qualitative content analysis, I inductively generated categories to examine why certain members are particularly dedicated to (re)producing collective narratives as well as to understand the core themes and morals of stories. The analysis illustrates why members act as community librarians, storytellers, external messengers, and social reporters to share myth and legends that have different effects: Narratives about group solidarity convey implicit imperatives that secure the existence and transformation of a community. The normative messages enable a mutual understanding and foster everyday support among long-term and potential new members. Stories that highlight the ethnic identity ensure differentiation from other sub-ethnic groups and strengthen the cohesion among members with hybrid identities. Hereby, members preserve the remembrance of a common origin as a central identity element even if the actual descent is not decisive for membership. Other narratives emphasize societal inclusion by portraying successful members as role models. Overall, collective narratives prevent the disintegration of diasporic communities with the potential to counter negative stereotypes attributed to ethnic groups perceived as an entity. Diasporic communities should be acknowledged as a stabilizing element of societies, as they promote social recognition of members and function as a counterbalance to experienced racial discrimination.
El enfoque inclusivo del Diseño Universal del Aprendizaje para estudiantes con discapacidad intelectual
Authors: López Guerrero Tatiana del Carmen , Mendoza Moreira Francisco Samuel
Published: July 2022

El sistema educativo ecuatoriano requiere de un método alternativo y efectivo que permita a los niños con discapacidad intelectual aprender como sus pares en un ambiente agradable, sin diferencias ni obstáculos. El presente trabajo es una investigación con enfoque narrativo basado en la recopilación de experiencias de expertos en la temática del -Diseño Universal del Aprendizaje- (DUA). La investigación inició unos meses antes de la pandemia declarada en marzo de 2020 con la finalidad de hacer una experiencia práctica en las aulas sobre la aplicabilidad y efectividad del DUA en la enseñanza regular, pero dada la extensión del confinamiento, se convirtió en una recopilación de información con acercamientos virtuales a los expertos y a los medios de información disponibles. Se extrajeron contenidos clave para orientar el trabajo docente e iniciar lo que podrí­a ser una transformación en la educación inclusiva ecuatoriana, ya no pensando que con solo modificar el currí­culo hay resultados, sino más bien ampliando las posibilidades de aprendizaje colectivo. El conocimiento y aplicación del DUA busca despertar tanto en estudiantes como en docentes, el interés para aprender y enseñar respectivamente, dentro del marco inclusivo. La instauración y práctica del mismo, tal como lo afirman un sinnúmero de testimonios, es evidente y posibilita que los estudiantes con discapacidad intelectual y en general con cualquier discapacidad, dejen de ser miembros pasivos dentro del aula y se conviertan en entes motivados, participativos, que pasen del estado integrado al incluido.

Authors: Chada Jithendra Sai Raja , Rao B. S. V. Rama
Published: July 2022

The hydrofoil is one of the typical factors that affect the vortex structure and flow characteristics of hydraulic machinery. In order to enhance the utilization efficiency of hydraulic machinery in marine energy, parallel grooves are proposed and applied to the hydrofoil. Following that, a numerical analysis is performed using the SST k- turbulence model, and the effects of hydrofoil profile, angle of attack, and flow are investigated. The profiles of NACA 0066, NACA 8412, NACA M2, and RAE 104 are considered for the study. The performance is analyzed based on the lift to drag ratio. The best model from this is given with surface modification and the flow study is carried out at different angles of attack. The modified profile of NACA 8412 with parallel groves has shown the highest lift to drag ratio at a 12-degree angle of attack.
