Cytotoxic effect of Centaurea solstitialis L. (Asteraceae) on cell cultures
Authors: Böke Eftal
Published: September 2023

Aims: The aim of this study was to investigate the cytotoxic effect of Centaurea solstitialis (C. solstitialis ) L. (Asteraceae) plant extract on A-549 lung cancer cells. Cytotoxicity is an important parameter to evaluate the lethal effect of plant extract on cancer cells. This study aims to provide information about the potential medicinal use of the plant.
Methods: In this study, plant specimens were collected from the campus area of Kırıkkale University during flowering in May-June and identified in ADO Herbarium. Dried and crumbled plant leaves were mixed with 70% ethyl alcohol to form a paste and this mixture was kept in a magnetic stirrer for at least 48 hours. It was then kept in a fume hood for at least 48 hours to dry and the dried material was labeled and stored in ependorf tubes. Cytotoxicity was determined by WST-1 assay and evaluated by examining the morphological characteristics of the cells. This study was conducted to understand the effect of C. solstitialis on cells and to evaluate its potential medicinal use.
Results: Different doses of C. solstitialis plant extract (200ug/ml, 100ug/ml, 0.05ug/ml, 0.025ug/ml, 0.025ug/ml, 0.0125ug/ml) were tested and the percentage of cell viability was calculated relative to the control group. The results revealed that dose 1 exhibited a cell viability of 26%, with dose 2 showing the highest cell viability at 38%, dose 3 at 74%, dose 4 at 80% and dose 5 at 96%. The toxicity levels of C. solstitialis plant extract were determined and apoptotic and necrotic effects were examined at the observed toxic doses. These findings highlight the potential cytotoxicity of C. solstitialis plant extract on A-549 lung cancer cells.
Conclusion: The results showed that C. solstitialis showed a cytotoxic effect and the percentage of viability decreased depending on the dose. As the dose applied to the cell decreased, the percentage of viability increased and the cytotoxic effect decreased. Apoptotic and necrotic effects observed at toxic doses suggest that programmed cell death mechanisms are induced. Further studies are needed to elucidate the underlying molecular mechanisms and to compare the cytotoxic effects of C. solstitialis with other Centaurea species.

Aims: Since the deterioration of the skin barrier plays a role in the development of atopic dermatitis, it is necessary to investigate the moisture and sebum content of the skin. In this context, our study aimed to evaluate the change of skin sebum and moisture content with treatment in children with atopic dermatitis.
Methods: This study is a cohort study. Patients aged 0-18 years, diagnosed with atopic dermatitis, and those who did not have any accompanying skin disease were included. Skin moisture and sebum levels were measured with a portable pen-shaped LCD Display Digital Skin Moist Oil Analyzer (Reyoung-Beauty, Guangdong, China) digital skin moisture and sebum measurement device from the cubital fossa before and 1 month after the treatment. Skin sebum and moisture were obtained as percentages.
Results: The median values of skin moisture and sebum content before treatment in 55 atopic dermatitis patients were 30.0 % (10.0-55.0) and 24.0% (16.0-49.0), respectively. The percentages of skin moisture and sebum content after treatment were 38.0 % (15.0-60.0) and 28.0 % (18.0-50.0), respectively. In atopic dermatitis patients, the increase in skin moisture and sebum percentages was statistically significant for both (p<0.001 and p=0.022, respectively)
Conclusion: Skin moisture and skin sebum contents improved significantly with treatment in children with atopic dermatitis. This situation highlights the importance of adherence to treatment and continuity of selected treatments in patients.
Modeling Multivariate Spatial Dependencies Using Graphical Models
Authors: Dey Debangan , Datta Abhirup , Banerjee Sudipto
Published: September 2023

Graphical models have witnessed significant growth and usage in spatial data science for modeling data referenced over a massive number of spatial-temporal coordinates. Much of this literature has focused on a single or relatively few spatially dependent outcomes. Recent attention has focused upon addressing modeling and inference for substantially large number of outcomes. While spatial factor models and multivariate basis expansions occupy a prominent place in this domain, this article elucidates a recent approach, graphical Gaussian Processes, that exploits the notion of conditional independence among a very large number of spatial processes to build scalable graphical models for fully model-based Bayesian analysis of multivariate spatial data.

RESUMEN:
Las interpretaciones sobre el patrimonio cultural de Santa Teresa han adoptado formas variadas a lo largo del tiempo, desde el análisis de su valor histórico y religioso, hasta su indudable estatus en la industria de objetos y reliquias. Sin embargo, en este artículo nos proponemos revisar otra parte de su legado, reflejado en su desafiante autoridad literaria, epistolar y pedagógica, en tanto estos tres espacios —el comunicativo, el íntimo y el comunitario— formaron parte de la elaboración de su propio modelo de santidad y de su inagotable y eficaz programa cultural y formativo.
ABSTRACT:
Interpretations of St. Teresa's cultural heritage have taken various forms over time, from the analysis of its historical and religious value, to its undoubted status in the industry of objects and relics. However, in this article we propose to review another part of his legacy, reflected in his challenging epistolary, corporal and pedagogical authority, and to endow it with value, while these three spaces, the communicative, the intimate and the communitarian, were part of the elaboration of his own model of holiness and of his inexhaustible and effective cultural and formative program.
Phenomenology of Borderline. To the Typology of Cultural Interference
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Girin Yu.N.
Published: September 2023

The article raises the question of the necessity to update the nomenclature of the humanities. A productive direction may be the appeal to the concept of borderline which has already been developed in a broad cultural field. However, using the concept of borderline requires adequate methodology which is not available within the modern scientific paradigm yet. Thus, the problem requires theoretical understanding from the point of view of phenomenology. What is meant by the phenomenological approach here is concentration on the anthropological, cultural (in a broad sense) reality of human existence. In this case, the phenomenology of works of art allows revealing much more meaning than traditional historical and cultural analysis. In other words, rather than study the correlation of forms, styles and movements, it is supposed to try to discover hidden narratives of the epoch of borderline as a special cultural landscape, since any borderline is, by definition, a chronotope of changes and renovations; it implies the emergence of a new quality of being, a new world relationship. The phenomenology of borderline reveals a dual cultural identity in which different semantic vectors are brought to the fore depending on the circumstances.
Coloristic Searches of Modern Russian Artists: The White Colour Palette of the Easel Painting by Maria Pak
Authors:   V.I. Surikov Moscow State Academic Art Institute, Sergeeva T.D.
Published: September 2023

The article attempts to consider the work of the Moscow artist Maria Pak in the context of coloristic searches in Russian painting based on artists’ work with the white colour. The article opens with a brief outline of the development of the doctrine of colour in the European art of the early modern and modern periods. The main part is devoted to the analysis of the latest exhibition of the easel painting (March 2023) by Associate Professor of the V.I. Surikov Moscow State Academic Art Institute, Maria Pak, student of I.L. Lubennikov. Particular attention is focused on the “winter” canvases in which the creative task is to paint white on white. The author of the article makes the conclusion that colour preferences are not only determined by social, national and other conditions for artistic culture development, but also closely related to a person’s ability to empathize. The author comes to this conclusion considering the white colour palette of M. Pak’s easel painting in a broad cultural context — appealing to the works of painters as well as to the poetic creations of Russian writers.
Ettore Scola. Historical and Family Chronicles of the 1980s
Authors:   State Institute for Art Studies, Balandina N.P.
Published: September 2023

The article explores the language and themes of the films made by Italian film director Ettore Scola in the 1980s. The author of the article considers this period of Ettore Scola’s career in the context of the general evolution of his cinematography and the development of Italian cinema — movement from early Italian-style comedies to historical frescoes and parables of elusive time. Scola’s films not only reflect the social, political and cultural changes in the Apennine Peninsula in the last three decades of the 20th century, but also address universal, philosophical themes. These melancholic stories often contain a warning of danger and a reminder of responsibility for our actions which can lead to irreparable consequences. In 1983, the director made one of his best and most famous films, Ballando, ballando, in which the characters do not speak a word. Presenting a Parisian ballroom as a model of history, Scola argues that the value of a person’s private life is undeniable, and that it is he, the hero emerging from the elements of everyday life — funny, absurd, and contradictory, but able to hope in spite of unbearable circumstances — who is its main protagonist. In The Family (1986), this model is a flat in Rome, where the protagonist’s family has lived for decades. Finally, Skola’s What Time Is It? (1989) develops the findings from his previous films, but unlike them, it does not present a group portrait in an interior setting against the backdrop of the 20th century but a dialogue between two characters — father and son — taking place during a city walk on a single day. However, this chamber family chronicle is also imbued with reflections on the relationship between an “ordinary” man and the time of big history.
“Near-Theatrical” Story on the Pre-Revolutionary Concert Estrada
Authors:   State Institute for Art Studies, Sarieva E.A. ,   Russian University of Theatre Arts — GITIS
Published: September 2023

The article discusses the evolution of the genre of improvisational story on the pre-revolutionary concert estrada using the example of stories on theatrical themes. Such stories were many on the concert estrada, as the performers who presented them knew the theatrical environment well. In the first half of the 19th century, the simplest type of story (close to true story anecdotes, “byvalschina”) was established — stories about reliable events in which the narrator was sure to add something of his own, fantasizing and improvising. The actor to be famous for performing true story anecdotes and byvalschina was M.S. Shchepkin. In the creative work of P.M. Sadovsky, there appears a more complex story type — a “skaz” where the author is replaced by the narrator. For the first time in the improvisational story, Sadovsky introduced social types — a merchant, a soldier, and a craftsman on whose behalf the story was narrated. In such cases, the speech conveyed the peculiarities and social characteristics, depending on the image being presented. Today, this genre of stand-up is often called “monologue in character”. The most complex story type, a “scene”, is distinguished by a dialogue that takes place between two or more characters. The first to perform “scenes” on the concert estrada was I.F. Gorbunov. Usually, “scenes” on theatrical themes were polemical and expressed the narrator’s attitude towards theatrical and literary figures. The plot of improvisational stories on theatrical themes was deliberately kept to a minimum because the main thing was the skill of speech transformations and improvisation. The happy combination of the author and the performer in one person was also of great importance.
The Golden Cockerel, 1914 and 1917, Designed by N. Goncharova. Specificity and Differences of Stage Design
Authors:   Russian State University for the Humanities, Voytova R.D.
Published: September 2023

This article is devoted to the study of the evolution of N. Goncharova’s artistic manner on the example of her stage designs for the 1914 and 1937 productions of The Golden Cockerel. The opera-ballet version of The Golden Cockerel is often described in detail in works devoted to S. Diaghilev and his theatre company, and the creative work of N. Goncharovа and M. Larionov. However, due to the fact that Goncharovа’s graphic heritage of the 1930s-1950s has been little studied so far, the scene design of the 1937 ballet version is almost not considered, nor is it traced within the general evolution of N. Goncharovа’s style. Comparing the two versions of scene design, 23 years apart, as well as identifying the influence of the changed external factors and the social context makes it possible to visually examine the changes in N. Goncharova’s artistic manner during emigration.
Reading Memoirs by T.N. Livanova: Portraits of Contemporaries. Part II
Authors:   State Institute for Art Studies, Petukhova S.A.
Published: September 2023

The article continues a series of studies devoted to the three-volume Memoirs by T.N. Livanova the publication of which is being prepared at the State Institute for Art Studies. The article considers several types of verbal portraits created by the memoirist. First, these are images of the people Livanova got acquainted with in the evacuation. Nowadays, almost nothing is known about them and it is the features of the text as such that remain the object of research. Another collection is made up of portraits of Livanova’s students, some of whom gained an odious reputation. A separate line of memoirs consists of “double” portraits not of musicians or musicologists but representatives of allied specializations of the humanities. Finally, roughly in the middle of Livanova’s narrative is an extended, multi-figured canvas dedicated to the Wipper family.
Sociocultural Modifications in the USSR of the 1960s-1980s
Authors:   State Institute for Art Studies, Dukov E.V.
Published: September 2023

The article examines the interrelated processes of new urbanization, the restructuring of the social structure of society and the intellectual atmosphere in the USSR in the 1960s-1980s. When analyzing the Soviet urban culture of that time, migration processes are emphasized, as well as the peculiarities of adaptation of rural migrants to the urban environment. The socio-cultural changes of the 1960s and 1980s brought to the fore the category of “personal life”, which is reflected not only in mass housing architecture and a variety of leisure activities, but also in art, in particular the cinema of those years. The article highlights the important role of samizdat not only in the completeness of the implementation of the literary process at that time, but also in the prompt response to the new linguistic picture of the country. The author emphasizes the growing critical and ironic component in the perception and understanding of Soviet reality in the general social climate of the period under review, including by cultural, scientific and artistic figures (among the main examples are the sarcasm of A.A. Zinoviev and the studies on the comic by Yu.B. Borev).
Gift-Giving Philosophy as Part of a Typological Model of Festivities
Authors:   State Institute for Art Studies, Mostitskaya N.D. , Mikhailov A.B. ,   Yangil Art Collection
Published: September 2023

The article explores a unique typological model of festivities as a methodological background for the gift concept analysis in the structure of festive communication. The relevance of research is recognized through correlation with such topics as “value transmission”, “social memory”, “festive culture” and “offering”. The authors of the article bring two questions to the fore: the mnemic function of a celebration and the role of a gift in value guidelines formation, i.e. the values which were communicated during festive ceremonies. The idea has been reflected in two concepts: first — in a holiday classification pattern, with examples of “explosive holiday”, “dynamic holiday” “lagging holiday” and “neutrally mnemic holiday”; second — in a hypothesis assuming that a festive communication pattern might be a subject to change through unveiling mnemic potential of a gift during a festive ceremony. The key assumptions of the article are proven through the semantic analysis of a unique artefact — a premium gold cigarette case with an image of the first Soviet coat of arms, a work by S.V. Chekhonin. N.V. Lisovskii and S.I. Aralov, who spoke for the Revolutionary Military Council of the 12th Army, awarded this case to S. Bekker, a participant in liberation battles for Kiev, in 1920. The cigarette case is considered as an offering and a gift. The authors analyse which holiday pattern the cigarette case is most likely to fit in. The novelty of research is that the authors highlight the role of a gift as a catalyst for festive communication. A gift is thought of as a cultural code of an event, value transmitter, and the very essence of a holiday idea. A gift has a great power which can either reinforce or ruin the festive communication model.
Painters of Modern Russia: The Search for a Measure of the Human in Art
Authors:   State Institute for Art Studies, Krivtsun O.A.
Published: September 2023

The subject of this study is the plastic and semantic searches of modern painters which are marked by reflection on the measure of the human in art and in life. The author believes that it is not worth revealing a single creative style vector in our contemporaries. The majority of creative practices inherit the most significant experiences of modernism: expressionism, cubism, abstraction, and suprematism. The creative method that appears to be most popular is the one in which the artist does not break with figurativeness, but significantly deforms it, working on the border of objectivity and abstraction. People’s disappointment in any socio-philosophical theories of the last century has produced the risk of a semantic dead end in goal-setting and motivation of their consciousness and behaviour. In this situation, artists, in particular painters, offer their research and answers. The paradoxical thing is that by refracting sad, oppressive and even harshly dramatic situations in art, painting demonstrates the effect of a “transformed feeling”: it conveys to the audience a sense of belonging, and thereby alleviates their own internal states. The article analyses the work of painters Viktor Kalinin, Natalia Nesterova, Larisa Naumova, Nikolai Rybakov, and Vasily Shulzhenko.

Cloud top heights and aerosol layer properties from EarthCARE lidar observations: the A-CTH and A-ALD products
Authors: Wandinger Ulla , Haarig Moritz , Baars Holger , Donovan David , van Zadelhoff Gerd-Jan
Published: September 2023

Abstract. The high-spectral-resolution Atmospheric Lidar (ATLID) on the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE)
provides vertically resolved information on aerosols and clouds with unprecedented accuracy. Together with the Cloud Profiling Radar (CPR), the Multi-Spectral Imager (MSI), and the Broad-Band Radiometer (BBR) on the same platform, it allows for a new synergistic view on atmospheric processes related to the interaction of aerosols, clouds, precipitation, and radiation at the global scale.
This paper describes the algorithms for the determination of cloud top height and aerosol layer information from ATLID Level 1b (L1b) and Level 2a (L2a) input data. The ATLID L2a Cloud Top Height (A-CTH) and Aerosol Layer Descriptor (A-ALD) products are developed to ensure the provision of atmospheric layer products in continuation of the heritage from the Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO). Moreover, the products serve as input for synergistic algorithms that make use of data from ATLID and MSI. Therefore, the products are provided on the EarthCARE joint standard grid (JSG).
A wavelet covariance transform (WCT) method with flexible thresholds is applied to determine layer boundaries from the ATLID Mie co-polar signal.
Strong features detected with a horizontal resolution of 1 JSG pixel (approximately 1 km) or 11 JSG pixels are classified as thick or thin clouds, respectively. The top height of the uppermost cloud layer together with information on cloud layering are stored in the A-CTH product for further use in the generation of the ATLID-MSI Cloud Top Height (AM-CTH) synergy product. Aerosol layers are detected as weaker features at a resolution of 11 JSG pixels. Layer-mean optical properties are calculated from the ATLID L2a Extinction, Backscatter and Depolarization (A-EBD) product and stored in the A-ALD product, which also contains the aerosol optical thickness (AOT) of each layer, the stratospheric AOT, and the AOT of the entire atmospheric column. The latter parameter is used to produce the synergistic ATLID-MSI Aerosol Column Descriptor (AM-ACD) later in the processing chain. Several quality criteria are applied in the generation of A-CTH and A-ALD, and respective information is stored in the products. The functionality and performance of the algorithms are demonstrated by applying them to common EarthCARE test scenes. Conclusions are drawn for the application to real-world data and the validation of the products after the launch of EarthCARE.
The stability of present-day Antarctic grounding lines – Part 2: Onset of irreversible retreat of Amundsen Sea glaciers under current climate on centennial timescales cannot be excluded

Abstract. Observations of ocean-driven grounding-line retreat in the Amundsen Sea Embayment in Antarctica raise the question of an imminent collapse of the West Antarctic Ice Sheet. Here we analyse the committed evolution of Antarctic grounding lines under the present-day climate. To this aim, we first calibrate a sub-shelf melt parameterization, which is derived from an ocean box model, with observed and modelled melt sensitivities to ocean temperature changes, making it suitable for present-day simulations and future sea level projections. Using the new calibration, we run an ensemble of historical simulations from 1850 to 2015 with a state-of-the-art ice sheet model to create model instances of possible present-day ice sheet configurations. Then, we extend the simulations for another 10 000 years to investigate their evolution under constant present-day climate forcing and bathymetry. We test for reversibility of grounding-line movement in the case that large-scale retreat occurs. In the Amundsen Sea Embayment we find irreversible retreat of the Thwaites Glacier for all our parameter combinations and irreversible retreat of the Pine Island Glacier for some admissible parameter combinations. Importantly, an irreversible collapse in the Amundsen Sea Embayment sector is initiated at the earliest between 300 and 500 years in our simulations and is not inevitable yet – as also shown in our companion paper (Part 1, Hill et al., 2023). In other words, the region has not tipped yet. With the assumption of constant present-day climate, the collapse evolves on millennial timescales, with a maximum rate of 0.9 mm a−1 sea-level-equivalent ice volume loss. The contribution to sea level by 2300 is limited to 8 cm with a maximum rate of 0.4 mm a−1 sea-level-equivalent ice volume loss. Furthermore, when allowing ice shelves to regrow to their present geometry, we find that large-scale grounding-line retreat into marine basins upstream of the Filchner–Ronne Ice Shelf and the western Siple Coast is reversible. Other grounding lines remain close to their current positions in all configurations under present-day climate.
Numerical study of the unsteady blade root aerodynamics of a 2 MW wind turbine equipped with vortex generators
Authors: Seel Ferdinand , Lutz Thorsten , Krämer Ewald
Published: September 2023

Abstract. In order to design vortex generators for modern multi-megawatt wind turbines accurately, the 3D behaviour of the boundary layer has to be considered. Due to the rotation of the blade, the lift-enhancing rotational augmentation has a considerable impact, especially in the inner blade sections.
To investigate the interaction of vortex generators and rotational augmentation, high-fidelity computational flow simulations by means of unsteady Reynolds-averaged Navier–Stokes methods are presented for a rotating blade of a generic 2 MW horizontal-axis wind turbine.
The inner blade section is analysed with and without vortex generators for two different pitch settings, including one causing largely separated flow. Two ways of placing the vortex generators on the blade with different radial starting positions are investigated in order to find out if the coexistence of the two lift-enhancement methods (i.e. rotational augmentation and vortex generators) is beneficial. All simulations are performed with the flow solver FLOWer, and the vortex generators are modelled by the introduction of source terms into the computational domain through a so-called BAY (Bender–Anderson–Yagle)-type model.
For the case without vortex generators, it is found that the strength of rotational augmentation largely depends on the effective angles of attack (i.e. the pitch setting). For the case with lower effective angles of attack, rotational augmentation is a cyclic phenomenon, whereas for the case with higher effective angles of attack, it generates large loads in the inner root section due to a constant centrifugal pumping mechanism in time.
The results from the cases with vortex generators display a rather destructive interaction of vortex generators and rotational augmentation on the torque. For low effective angles of attack and thus attached flow conditions, vortex generators exhibit slight losses compared to the case without vortex generators, as they inhibit spanwise flow through rotational augmentation. For high effective angles of attack, the vortex generators placed over 30 % of the blade produce an increase of 3.28 % in torque compared to the case without vortex generators and high centrifugal pumping.

Effects of Food Additives and Preservatives on Processed Food
Authors: Neelam Mall , Mishra Sunita
Published: September 2023

Foods are substances or mixture of substances both solid and/or liquid, which are intended for human consumption or ingestion for their nutritional pleasurable benefits. Food additives are organic substances that are intentionally added to food in small quantities during production and processing to improve or maintain the quality of the processed foods. Food preservatives is a class of food additives that help to present food spoilage by preventing the growth of microorganism .The effectiveness of preserve foods were tested with two parameters such as pH value ,moisture content at the interval of 0 days ,5 days, 15 days, 25 days. Two types of methods are used to preserve i.e. traditional and modern method. Under the traditional method I use salting and sun drying method and under the modern method, Ultrasonication and microwave method are used .In ultrasonication method, Nano particle such as Titanium dioxide is use as a preservative. Result of processed foods on physico-chemicals showed that pH was reduced on 25th days and moisture content was reduced on 25th days. With the ever growing world population and the need to store and transport the food from one place to another where it is needed food preservation becomes necessary in order to increase its shelf life and maintain & improve the quality of processed foods .The most common food additives and preservatives used are sodium benzoate , sodium chloride, titanium dioxide .The aim of this review is to summarize current information about food additives and its effects and increase the shelf life of processed foods.
An Efficient Technique of Wavelength Severance of Sodium Doublet Lines Using Diffraction Grating
Authors: Sachana C. S.
Published: September 2023

The lamp using Sodium vapor is used widely as a light source in experiments related to diffraction grating. The main point of sodium is that,it has high end emission wavelengths values. Also it is to be noted that without the help of sensitive equipment, the values of its wavelength cannot be measured. The purpose of this paper is to find out the wavelength of Sodium Doublet Emission (SDE) lines using diffraction grating. In this paper, it is proposed to find the values of SDE lines, F1 and F2, and also the mean wavelength as well as difference between the two SDE lines of sodium. In this approach, standardizing a spectrometer for evaluating the SDE lines has been proposed with the help of interference pattern created. With the aid of diffraction grating it is possible to obtain a well-defined and well resolved spectrum for the analysisofSDE lines. In this approach, the values for D1 and D2 are given by 588.9950 and 589.5924 nanometres respectively. In addition to the above, wavelength of SBE lines is evaluated and compared with theoretical value. The other parameters like angular separation, resolving and dispersive power of spectrum are also evaluated using this technique.
Common Fixed Point Theorems Under Strict Contractive Conditions in Fuzzy Metric Spaces
Authors: Rani Rashmi
Published: September 2023

Fuzzy sets originally introduced Zadeh. Using Concept of fuzzy sets, various theories regarding giving new concepts of fuzzy metric spaces were considered by various authors. After that, many authors have studied fixed point theory in such spaces and proved various fixed point theorems in such spaces. In 1975, Kramosilet al. have introduced the concept of fuzzy metric spaces. In this paper, using concept of fuzzy metric space given by Kramosil et al., we prove common fixed point theorems for weakly compatible mappings satisfying strict contractive condition in fuzzy metric spaces by using property (E.A). Our proved results generalize known fixed point theorems in literature. We prove two common fixed point theorems in this paper, one for four maps and other one for two maps. Mathematics subject classification: 54E40, 54E35, 54H25.
