“Frost” on Tin — a Technique of Russian Chest Production
Authors: Pudov Gleb A.
Published: August 2022

“Frost” on tin is a decorating technique widely used in the Russian chest production of the 19th—20th centuries. The technology is based on the crystallization of molten tin plate (a mixture of tin and lead) with the addition of water droplets and a chemical reaction on the crystallized tin plate of a mixture of sulfuric and nitric acids. The technique of “frost” on tin as one of the means of decorating chests and caskets has not been previously devoted to a special study. The purpose of this paper is to identify the origins and significance of this technique in the history of chest production in Russia, to determine its artistic features in comparison with foreign items, as well as to analyze specific works. Items from the collection of the Folk Art Department of the State Russian Museum were used as research material. The chronological framework of the study is the 19th—20th centuries. The author of the paper concludes that the “frost” on tinwas extremely popular over a vast territory. This technique was not a feature of the applied art only of Veliky Ustyug. For a long time, it played an important role in decorating chests, caskets, cellarets and boxes. In some centers, this technique successfully competed with painting. Perhaps, the “frost” on tin was a borrowed phenomenon. This had become possible due to the favorable conditions associated not only with trade but also with the development of the culture of certain regions of Russia. The foreign technique was adapted by Russian craftsmen in accordance with local artistic traditions.
Problematic Areas in English-Language Research on Multiplayer Role-Playing Games
Authors: Rodionova Anastasia A.
Published: August 2022

This article examines contemporary English-language research on multiplayer role-playing games. There can be identified several large problematic areas. The article aims to trace how the largest of them are formed, to describe the process of their emergence and development at the present time, as well as to describe the main points that researchers have worked out. The discussion of this topic makes it possible to understand how the conceptual apparatus of the research on multiplayer role-playing games is changing in modern English-language studies.

One of the major problematic areas is related to the study of the participants’ motivation in multiplayer role-playing games. This problematic area seeks to answer the question: “What keeps players coming back to the same game over and over again?” Scientists working in this field believe that players return to virtual worlds to get opportunities for virtual earnings, a variety of social interactions, role-playing, and because of the spirit of exploration. Another problematic area is based on the study of player-to-player relationships and explores the construction of social connections around a video game. The researchers are interested in the issues of leadership and social consolidation, which takes the form of guilds in multiplayer role-playing games. The third major problematic area arises from the study of player self-identification. The scientists are trying to understand which parts of a player’s identity influence their experience and how it is mediated. The research on multiplayer role-playing games is a complex interdisciplinary phenomenon that requires involving specialists from different fields, in particular economists, sociologists, linguists.
New Russian Iconography “The Resurrection with the Descent into Hell”: Compositional Variations
Authors: Ivanova Svetlana V.
Published: August 2022

The article deals with the iconography of the Easter holiday in Russia, specifically the image of “The Resurrection with the Descent into Hell”, common to the Russian art of the 17th—18th centuries. This image arises as a result of copying Western European engravings by Russian icon painters. The engravings illustrate the Apostles’ Creed — its fifth formula, which is different from the Orthodox one. In the Orthodox Creed, the fifth formula is called the Resurrection on the Third Day, in the Apostolic one — the Descent into Hell and the Resurrection. The Apostolic Creed is included in the Protestant Bibles, which turn out to be a source of new plots and compositions for Russian painters.

In the process of its existence in Russian art, the new image of “The Resurrection with the Descent into Hell” is filled with additional plots, but most importantly, its main compositional scheme changes.

The two main plots that make it up — the Descent into Hell and the Resurrection — are located on the icon field in different ways, depending on the interpretation of the painters or in strict accordance with the engraving model. Based on the location of the plots that make up the icon, there are distinguished compositional variants with either sequential or vertical arrangement of the plots. Within the first variant, there may be some subgroups: “The Descent into Hell” (whose topos is the underworld) is located below “The Resurrection” (whose topos is earthly space). We see that the iconographers correlate “The Descent into Hell” with the image of “Anastasis” (the Orthodox icon of the Resurrection). This follows from the way the location of the plots changed, when on older monuments — in contradiction with the composition of the engravings — “The Resurrection” had been located below.

The most famous in Russian art is the vertical compositional version. The two plots are located strictly above each other, forming the central axis of the entire iconographic work, around which other storylines are added. In accordance with the Western European engravings, “The Resurrection” is located here in the upper register. These various modifications must be taken into consideration in order to understand both the genesis and the main content of the new iconography.
The Archetype of Ideal City in the Naive Painting of Russian Artists of the 20th Century
Authors: Kashkova Alisa I.
Published: August 2022

The archetype of ideal city is one of the most significant in the development of world culture due to the fact that the idea of perfect world order, embodied in a spatial image, has reflected from ancient times the most important value orientations of the cultures of the Middle Ages and the Modern Times, both of the West and of the East. In Russian culture, the archetype of ideal city is embodied in the images of the Heavenly Jerusalem and the City of Kitezh. We have chosen as an object of research the works of Russian naive artists of the 20th century, which allows us to trace the development dynamics of this archetype in modern Russian culture. The subject of the research is the embodiment and peculiar interpretation of the archetype of ideal city in the works of naive artists Pavel Petrovich Leonov (1920—2011), Vagan Yerevandovich Sakiyan (1926—2002), Yury Dmitryevich Deev (1944—1998). The aim is to identify culturally conditioned interpretations of the national archetypes of ideal city in the naive art of the twentieth century. The article also conducts a multi-level cultural research of the creative world of the naive artists P.P. Leonov, V.E. Sakiyan and Yu.D. Deev, revealing the most characteristic features of this art phenomenon. The study of national Russian culture involves referring to a number of works on cultural studies, philosophy, mythology, history, philology, folklore studies, etc., devoted to the issues of national archetypes. The analysis of the naive painting works by Russian artists is carried out on the basis of cultural-philosophical, comparative-historical, typological, and analytical approaches. The naive art as a cultural phenomenon of Russian culture is very little studied in modern science; meanwhile, it combines many different cultural-psychological, cultural-historical and socio-cultural phenomena.
Initial Survey of Staphylococcus Bacteriophages and Simple Modifications in the Enrichment Method for Enhancing Plaques
Authors: Rai Akanksha , Khairnar Krishna
Published: August 2022

Isolation of bacteriophages against Staphylococcus aureus is difficult when compared to the bacteriophages of other genera. We did a preliminary survey for the presence of bacteriophages of S. aureus and Escherichia coli in the environmental water samples. We did not get bacteriophages against S. aureus, but bacteriophages against E. coli were ample. Subsequently, a river-water sample was taken and through the enrichment method with some modifications, we got a bacteriophage against a methicillin-resistant S. aureus. Here, we are reporting simple changes in the enrichment method to enhance plaques that have an extremely tiny and turbid morphology. This can be useful for researchers facing difficulty in finding lytic bacteriophages from water samples.
Role of osmoprotectants: transgenic approach for different stresses
Authors: . Prabhavathi , Bamel Kiran , Mal Anuradha , Pandey Roopali
Published: August 2022

Plants have an in-built mechanism to cope with various environmental stress conditions. One such approach is activation of genes which governs the stress conditions. Out of the many stress related genes, some genes code for osmolytes or osmoprotectants. These belong to a group of low molecular weight compounds which are non-toxic compounds and help in stabilizing cellular structures and enzymes during the stress situation. Since the family is quite big, so for a fair understanding, these are grouped into different categories. For a better understanding of osmoprotectant related gene expression and their regulation in response to biotic and abiotic stress, this review cites the recent research works related to osmoprotectants and the genetic approach undertaken with these genes in other plant species.
Elucidating the Dynamics of Polymer Transport through Nanopores using Asymmetric Salt Concentrations

Published: August 2022

While notable progress has been made in recent years both experimentally and theoretically in understanding the highly complex dynamics of polymer capture and transport through nanopores, there remains significant disagreement between experimental observation and theoretical prediction that needs to be resolved. Asymmetric salt concentrations, where the concentrations of ions on each side of the membrane are different, can be used to enhance capture rates and prolong translocation times of electrophoretically driven polymers translocating through a nanopore from the low salt concentration reservoir, which are both attractive features for single-molecule analysis. However, since asymmetric salt concentrations affect the electrophoretic pull inside and outside the pore differently, it also offers a useful control parameter to elucidate the otherwise inseparable physics of the capture and translocation process. In this work, we attempt to paint a complete picture of the dynamics of polymer capture and translocation in both symmetric and asymmetric salt concentration conditions by reporting the dependence of multiple translocation metrics on voltage, polymer length, and salt concentration gradient. Using asymmetric salt concentration conditions, we experimentally observe the predictions of tension propagation theory, and infer the significant impact of the electric field outside the pore in capturing polymers and in altering polymer conformations prior to translocation.
Atomic scale mechanism of Pt catalyst restructuring under a pressure of gas

Published: August 2022

Heterogeneous catalysis is key for chemical transformations. Understanding how catalyst active sites dynamically evolve at the atomic scale under reaction conditions is a prerequisite for accurate determination of catalytic mechanisms and predictably developing catalysts. We combine in-situ observation and Machine Learning accelerated first-principle atomistic simulations to uncover the mechanism of restructuring for Pt catalysts under a pressure of carbon monoxide CO. We show that a high CO coverage at a Pt step edge triggers the formation of atomic protrusions of low-coordination Pt atoms, that then detach from the step edge to create sub-nano-islands on the terraces, where undercoordinated sites are stabilized by the CO adsorbates. These studies open an avenue to achieve an atom-scale understanding of structural dynamics of more complex metal nanoparticles under reaction.
Stacked 3D Antiaromaticity in the π-Congested Space Between the Aromatic Rings in the Anthracene Dimer

Published: August 2022

Substance containing two π-congested aromatic systems are attractive targets in synthetic studies as well as efforts designed to explore the unique properties that originate from π-congestion. Since the time of the computational studies by Schleyer and Warner, the concept of stacked 3D aromaticity created by the encounter of two antiaromatic rings has received much attention. In contrast, questions about what happens when two aromatic rings are closely stacked have remained unanswered. To the best of our knowledge, only one computational study has been performed by Herges, the results of which suggest that [2.2]paracyclophane, possessing short distance (<3.00 Å) between two aromatic ring planes, has a paratropic ring current between two the benzene rings. This observation is consistent with the conclusion that stacked 3D antiaromaticity exists within the π-congested space between aromatic rings. Herein, we investigated the 3D antiaromaticity of highly -congested anthracene dimers using anthracenophane, which possesses a short inter-plane carbon-carbon distance of ca. 2.80 Å. The absorption spectrum of this substance contains a weak broad band from 450 to 550 nm that is attributed from HOMO-LUMO transition. These properties exist in planar cyclooctatetraene derivatives that having 8π-electron antiaromaticity. The results of nucleus-independent chemical shift and anisotropy of the induced current density calculations indicate that relatively weak antiaromatic character exists between the central six-membered rings of the two anthracene moieties in anthracenophane. In addition, an attempt to enhance the stacked 3D antiaromaticity of anthracenophane using pressure to enhance π-congestion using was unsuccessful.
Fe(III)-Catalysis in Flow Enables Bimolecular Proton Transfer as an Alternative to Superelectrophiles in Carbonyl-Olefin Metathesis

Published: August 2022

Catalytic carbonyl-olefin metathesis has emerged as a new strategy for the direct formation of carbon–carbon double bonds. Successful approaches for ring-closing carbonyl-olefin metathesis exist, but limitations remain in accessing systems larger than 5-membered rings. Currently available strategies rely on Lewis acidic superelectrophiles as stronger catalysts, which require precious metal additives for their formation upon chloride abstraction from otherwise environmentally benign metal salts, such as FeCl3. Herein we report the development of a continuous flow reactor that overcomes this challenge and can access 6-membered rings using FeCl3 as the Lewis acid catalyst. The plug-flow reactor design is user friendly, benchtop amenable, and demonstrates up to 200x improved reaction efficiency over batch conditions. Computational investigations reveal that this transformation proceeds through an unprecedented bimolecular stepwise pathway via intermolecular proton transfer. These insights represent a significant advance for catalytic carbonyl–olefin metathesis and are expected to spur future developments in catalyst design and reaction scope.

Authors: Al-Tamimi Abdulla Isa , Aljirdabi Noof Sami , Hashem AlMosawi Sayed Mohammed
Published: August 2022

Background: Diabetes mellitus results from defects in insulin secretion, resistance to insulin action, or both. Hyperglycemia causes small vessel diseases and thus affects the retina, kidneys, and nerves. An effect of diabetes that is not entirely understood is cognitive dysfunction. Methods: This case-control study aimed to study the cognitive function of the participants, which included 25 diabetics and 72 without diabetes as per the inclusion exclusion criteria. Participants underwent assessment of cognition by 3MS exam, and personal data was collected. 23 participants were excluded by the exclusion criteria. Age, gender, comorbidities, education, and HbA1C were correlated with the scores. The data were analyzed by Excel version 2013. Results: The group with diabetes showed a significant decrease in 3MS scores in comparison to the control group (90.11 ± 0.75 in controls versus 86.27 ± 1.24 in patients with diabetes, p < 0.05). People with diabetes of higher age groups scored significantly lower than the control of higher age groups (p<0.05). There was a significant relationship between cognitive scores and dyslipidemia in patients with diabetes and control samples (87 ±2.03 in patients with diabetes group with dyslipidemia versus 92.50 ± 2.09 in the control group with dyslipidemia, p< 0.05). Undergraduate controls scored higher than patients with diabetes undergraduates, p < 0.05. The correlation with gender as well as HbA1c was not significant (p>0.05). Conclusion: It has been established that diabetes decreases cognitive function. It is important to highlight the importance of testing cognitive function routinely in patients with diabetes to prevent further complications by early detection and management.

Authors: L Bashmi , H Alnashmi , D Alhasan
Published: August 2022

Background: The COVID-19 pandemic is a global health crisis with a likely long-term psychological impact on healthcare workers (HCWs). As the pandemic moves towards endemic status, little knowledge exists on how it has affected HCWs in the Kingdom of Bahrain. This study aims to evaluate the psychological impact and related factors of HCWs during the COVID-19 pandemic. Factors were assessed at two time periods: 1- July 2020 (T1: 6 months after the pandemic started in Bahrain) and 2- 6-month follow-up during January 2021 (T2: 12 months). Methods: An online cross-sectional survey using standardized questionnaires; Impact of Event Scale-Revised (IES-R), the Beck Anxiety Inventory (BAI), and factors including lifestyle, exposure to COVID-19, and knowledge of the centre’s psychological support services was circulated during both the time periods. Results: Based on a sample size of 366 (T1) and 537 (T2) HCWs, mild/positive PTSD prevalence increased from 18.9% (T1) to 19.6 % (T2), but anxiety decreased from 31.1% (T1) to 27.4% (T2). Sleep-related disturbances significantly decreased from T1 to T2 (32.5 % vs 24.8%, p = 0.013). Although the frequency of HCWs with psychological distress and anxiety did not change significantly over time, there was a decrease in severity of both psychological distress (p=0.06) and anxiety (p=0.005). HCWs (75%) who were aware of available psychological support services also had lower IES-R and BAI scores. Conclusion: COVID-19 has caused psychological distress and anxiety to HCWs, but rates were lower compared to other studies. Further development of COVID-19 leadership strategies incorporating interventions focused on psychological support for HCWs is needed.

A Clinical Approach To Juvenile Parkinsonism During Pregnancy
Authors: Hussain Aseel Ahmed , Ahmed Mooza Rashid
Published: August 2022

Juvenile parkinsonism is a rare disease affecting patients younger than the age of 21 years. When superimposed with pregnancy, most physicians fear its health complications and the role of the treatment and its safety for the fetus. This case presents a 37-year-old woman diagnosed with juvenile parkinsonism who was blessed with her second child, eight years after her first. Despite all the odds, concerns, and warnings from family and physicians, the patient was determined to conceive, avoiding all means of contraception. During pregnancy, the patient experienced multiple hypoglycemic attacks and was diagnosed with gestational diabetes mellitus, which was controlled accordingly. The patient also suffered from motor impairments that worsened with the progression of pregnancy. However, the patient regained previous motor function upon delivery. The expectation that pregnancy may permanently worsen the symptoms of Parkinson’s disease is not explicit; some pregnancies are uncomplicated by Parkinsonism yet complicated by pregnancy-induced medical conditions. As demonstrated in this case, family support and care, alongside continuous maternofetal monitoring, aids in the success of pregnancy in patients with juvenile Parkinson’s disease regardless of their risks.
