A Local Hybrid Exchange Functional Approximation from First Principles
Authors: Holzer Christof , Franzke Yannick J.
Published: May 2022

Local hybrid functionals are a more flexible class of density functional approximations allowing for a position-dependent admixture of exact exchange. This additional flexibility, however, comes with a more involved mathematical form and a more complicated design. A common denominator for previously constructed local hybrid funtionals is usage of thermochemical benchmark data to construct these functionals. Herein, we design a local hybrid functional without relying on benchmark data. Instead, we construct it in a more ab initio manner, following the principles of modern meta-generalized gradient approximations and considering theoretical constrains. To achieve this, we make use of the density matrix expansion and a local mixing function based on an approximate correlation length. The accuracy of the developed density functional approximation is assessed for thermochemistry, excitation energies, polarizabilities, magnetizabilities, NMR spin–spin coupling constants, NMR shieldings and shifts, as well as EPR g-tensors and hyperfine coupling constants. Here, the new exchange functional shows a robust performance and is especially well suited for atomization energies, barrier heights, excitation energies, NMR coupling constants, and EPR properties, whereas it looses some ground for the NMR shifts. Therefore, the designed functional is a major step forwards for functionals that have been designed from first principles.

Objective: As a systemic inflammatory skin disease, psoriasis vulgaris (PS) is associated with cellular immune mechanisms. We aimed to evaluate oxidative stress markers and ischemia modified albumin levels in patients with PS and controls.Materials and Methods: The participants (over age of 18) who applied to the dermatology outpatient clinic between September 2020 - May 2021 and diagnosed with PS (n=50) were enrolled into the study. Oxidative stress markers such as nitric oxide (NO), malondialdehyde (MDA), 8-hydroxy 2-deoxy guanosine (8-OHdG), superoxide dismutase (SOD), glutathione peroxidase (GPx) parameters and ischemia modified albumin (IMA) levels in patients with PS and controls were evaluated.Results: A total of 100 volunteers, 50 with PS and 50 healthy controls were enrolled in the study. In the measurements of oxidative stress markers, GPX, 8-OHdG, MDA, IMA, IMA/Albumin and NO parameters were found to be statistically as significant between the patient and control groups. Also, SOD, 8-OHdG, IMA and NO were found to be statistically as significant between two psoriasis severity index (PASI) groups.Conclusion: Elevated levels of 8-OHdG, MDA, IMA, IMA/Albumin, NO and decreased levels of GPx were observed in patients with PS. To clarify this topic, further and comprehensive studies are needed.

THE UNITY OF MONUMENTAL SCULPTURE AND THE ENVIRONMENT IN THE MONUMENT “TO THE FIRST BUILDERS OF KOMSOMOLSK-ON-AMUR”: TO THE QUESTION OF THE PROBLEMS OF THE EARLY WORK OF V.E. GOREVOY
Authors:   A.I. Herzen Russian State Pedagogical University, Sazonov Vadim V.
Published: May 2022

The article deals with the problem of synthesis of sculpture with natural and architectural spaces. Attention is drawn to the peculiarities of human perception of this cultural phenomenon. Already in the 1960s, there was considerable interest in the effect of including the surrounding landscape in the figurative structure of an architectural and sculptural ensemble. The author reveals how the creative method of V.E. Gorevoy, one of the largest sculptors of Leningrad-St. Petersburg over the past fifty years, was formed against the background of a powerful rise in monumental sculpture and memorial architecture. His early work reflected the artistic problems of the era in the history of Soviet monumental art. The sculptor was involved in the process of solving complex creative tasks, mainly the task of creating a special environment by means of sculpture that affects the emotions and patriotic feelings of the viewer.
PERSONAL STORYTELLING IN AUTOBIOGRAPHICAL COMICS: FORMS OF REPRESENTATION
Authors:   HSE University, Lushkin Sergei S.
Published: May 2022

The article provides to the problem of identity in autobiographical comics. In the recent years authors of comics have been increasingly addressing the topic of identity search, putting autobiography in the foreground. This study attempts to identify the most distinctive narrative strategies in autobiographical comics and to contextualise them within a new research field, one in which the authors' “experiments” in personal narrative are realised. The focus is on the two main methods of autobiographical storytelling employed in the work of comics. One is structured narrative and the other has more literary references and is similar to literary prose. The comparison of these methods has led to the question of the true identity of the author in the works he creates.
CORMAC MCCARTHEY'S NOVEL “NO COUNTRY FOR OLD MEN” AND ITS SCREEN ADAPTATION BY THE COEN BROTHERS
Authors:   The Russian Presidential Academy of National Economy and Public Administration, Cherkashina Margarita V.
Published: May 2022

In 2007, McCarthy's novel became the first experience of screen adaptation in the Coen brothers’ career, who had previously developed their own scripts only. They cut several key scenes of the novel. For example, those when each of the three main characters having their military background manifests himself as a Nietzsche’s Übermensch, ready to confrontate with others (the Coens made one of them be the protagonist, it's Sheriff Bell who does not accept the incomprehensible new world because of its total immorality). The person with healthy instincts, Bell had transformed by the Coens into a sort of a perfect knight, the new generation calculated killer Chigurh – in a total psycho, and his victim Moss – just in a man “who's been underestimated by others for so long that he's come to overestimate himself”. McCarthy's bitter irony grows out of his novel structure (mise en abyme) mostly. At the same time the Coens movie brilliance is based on their canticle of Absurd, when the crazy killer flips a coin with his victims.
THE THEME OF LONELINESS IN SOFIA COPPOLA’S OEUVRE
Authors:   Russian State University for the Humanities, Soboleva Valeria S.
Published: May 2022

The theme of a human's estrangement from society or from himself has become a relevant object of study many social sciences of the twentieth century. Then the dominant existential paradigm served as fertile ground for the creation of a number of films dedicated to the representation of the phenomenon of loneliness, thereby prompting researchers to study the features of this phenomenon in cinema. The article focuses on identifying the essence and specificity of the theme of loneliness as a socio-cultural phenomenon on the example of the films of the outstanding modern director, the daughter of an influential figure in American cinema Francis Ford Coppola, Sofia Coppola. Based on the analyzed images, the author concludes that, despite the previously known cinematic techniques and plot moves in Coppola's works that convey a feeling of loneliness (the character's unstable emotional state, his difficulties of interaction with society, etc.), the director, however, rethinks this complex of ideas and introduces his own special, delicate vision of such a complex problem.
DRAMATIC CONFLICT: INTERNAL CONTRADICTION AS A PROJECTION OF ACTION IN FEATURE FILMS
Authors:   Russian State University for the Humanities, Kolotaev Vladimir A.
Published: May 2022

I consider the reason to apply the basic relations of the pair of categories of the theory of dramaturgy, dramatic conflict and action, in relation to cinematography as determining the trajectory of the hero’s path. Through consideration of different points of view on what is primary, conflict or action, analyzing the impactful theories of drama, I prove that in feature films, psychological problems, an unremovable internal contradiction that puts the hero before a choice, is the trigger mechanism for action, as a chain of events that form a character arc. The reflection on the nature of the dramaturgical conflict, introduced by Hegel in his Aesthetics, attracted the attention of researchers in the 20th – 21st centuries, who generally considered the action as a kind of event that causes a clash of forces. Under the influence of Freud’s psychoanalysis, in many circumstances, the conflict is seen as an internal condition for the development of the organic form, and in relation to film dramaturgy, as an internal unresolved contradiction that causes a reaction from the environment and provokes external events that push the hero to actions, and the characteristics of the last is fully determined by the stage of development of his or her identity.
TO THE THEORY OF DARK MEDIA
Authors:   Russian State University for the Humanities, Markov Alexander V.
Published: May 2022

The concept of dark media, justified by Eugene Thacker, fully fits into today studies of the contingent. This article aimed to explore the potential of classical media theory to clarify the functional boundaries of this concept. I prove that it is possible to substantiate dark media as a phenomenon only by recognizing the connection between the main and auxiliary media, and then showing how this connection contributes to the transition from clear to dark media and vice versa. Building on the theory of corporeal media dating back to Giambattista Vico, critically rethinking the formalizing media theory from Wolfgang Riepl to Marshall McLuhan, I refine the concept of dark media as opposed not only to the concept of clarity, but also to the concept of the historical age, the concept of the class of messages and the concept of a group of interrelated practices, including practice of writing, each time undermining the influence claims of these concepts.

Published: May 2022

Free radicals can trigger various diseases, such as cancer, cardiovascular, arthritis, diabetes, neurological disorders, and aging. Thus, antioxidants are needed to reduce these free radicals. The peel of the purple passion fruit (Passiflora edulis f. edulis Sims) has many phenolic compounds that indicate antioxidant capacity. This study aims to determine the percentage yield and total phenolic contents in the ethanol extract of purple passion fruit peel. Extraction of purple passion fruit peel using the method of maceration with ethanol solvent. Measurement of total phenolic levels in ethanol extract from purple passion fruit peel using the UV–Vis Spectrophototometry method with Folin-Ciocalteu reagent. The principle of this method is based on the reagent between gallic acid and the Folin-Ciocalteu reagent that will produce a molybdenum-tungsten complex. Furthermore, the addition of Na2CO3 solution will change the color of the solution to blue, and its absorbance can be measured at a wavelength of 765 nm. The results showed that the ethanol extract from purple passion fruit peel yielded 1.363% and total phenolic levels of 30.758 mg of gallic acid equivalent per the gram of extract. The existence of the total phenolic content proves that the ethanol extract from purple passion fruit peel has the potential to be used as an alternative source of natural antioxidants.
