Published: December 2020

Vitiligo is a common skin disease characterized by idiopathic progressive skin hypomelanosis. Vitiligo is associated with several comorbid autoimmune diseases such as localized scleroderma. This article demonstrates the general development mechanism of these pathologies, as well as the key aspect of cross-effect between autoimmune diseases on the molecular level. Recently, dermatologists have noted the increasing number of patients suffering from combined pathologies. Such patients (in pediatrics) have torpid course of disease and no pathognomonic symptoms. That exaggerates the diagnostics and adequate therapy prescription. This leads to increased awareness among physicians of different specialties on possible combinations, clinical presentation and pathogenesis aspects of such conditions.

Psoriasis is multifactorial systemic disease characterized by excessive hyperkeratosis due to impaired keratinocytes proliferation and differentiation. This disease often manifests in childhood and it is usually associated with the development of comorbid conditions some of which are combined by the term «psoriatic march» (obesity, metabolic syndrome, etc.). The course of psoriasis and related comorbidities in children has several specific features that determine topicality of studying all the aspects of clinical diagnosis and prevention in childhood. The article summarizes recent ideas on the prevalence, pathogenesis features and early diagnosis of comorbid diseases in children with psoriasis.
Analysis of Risk Factors Affecting Skin Mastocytosis in Children: Cross-Sectional Study
Authors: Kasikhina Elena I. , Kruglova Larisa S. , Vashchenko Mariya O. , Mayorov Roman Y.
Published: December 2020

Background. Skin mastocytosis is rare disease that is diagnosed in most children under the age of 2 years. The date on rash regression dynamics and disease symptoms is not fully presented in the literature.

Objective. The aim of the study was to analyze risk factors associated with clinical manifestations and regression time of skin mastocytosis in children.

Methods. The study includes data on 28 children aged from 3 months to 12 years who has undergone outpatient care and observation in Moscow Scientific and Research Center of Dermatovenerology and Cosmetology of Moscow City Health Department in the period between January 2016 and November 2019. The data about diagnosis was obtained from medical records.

Results. Maculopapular skin mastocytosis (MPSM) was diagnosed in 28.6% of children, solitary mastocytoma — in 71.4%. The analysis of clinical course of skin mastocytosis has shown constantly relapsing process and slow spontaneous rash regression in more than 50% of children. Diffuse skin rash, flushing reactions, persistent skin itching or its combination with hepatomegaly or neurological symptoms were prevalent among MPSM manifestations. Risk factors affecting delayed regression of skin mastocytosis in children with MPSM are: late onset, area of skin lesions, comorbidities, severity of reticular vascular pattern at dermatoscopy. Severity of skin lesions did not affect the tryptase activity. The major risk factor affecting the delayed regression of solitary mastocytoma is rash injury (OR 6.10, 95% CI 3.66–16.73). The severity of reticular vascular pattern in skin mastocytosis foci has varied depending on the severity of skin lesions.

Conclusion. Half of all children with skin forms of mastocytosis have delayed rash regression. This causes high concern among parents and violates social adaptation of children. Timely assessment of risk factors alongside with dynamic assessment of the dermatoscopy patterns and tryptase activity are important for implementation of correct follow-up monitoring and management for children. Rash (of any localization) injuries should be avoided to prevent delayed regression of the disease in children with skin forms of mastocytosis.
DETECTION OF RESIDUAL STRESSES IN COATINGS OBTAINED BY THE METHOD OF ARC METALLIZATION WITH A PULSATING SPRAYING FLOW
Authors: O. M. Serenko  , I. V. Zakharova
Published: December 2020

Purpose. The authors propose to develop a mathematical model for the calculated determination of residual stresses in arbitrary layer of a thermal gas coating based on the change magnitude in the base geometry (sample deflection) and the variation law of the layer thickness derivative, further regulation of these stresses by changing the technological parameters of spraying for each type of sprayed coating. Methodology. Based on known works on stress detection of in welded joints, the approach of determination of samples deflection after layer-by-layer spraying was developed. These deflection parameters are the basis for the developed mathematical model of influence on the stress state. The data on the study of the main types of residual (internal) stresses, as I type, distributed in the volume of the whole part (sample) with coating, and II type, localized in the volume of sprayed particles, are systematized. Findings. We presented investigations of the residual stresses arising in the applied layer, the magnitude and nature of the distribution of which depend on the type, base and sprayed materials, methods and parameters of spraying, the rigidity of the part, and other factors. The important role of evaluating residual stresses in a thermal gas coating by the calculation method is shown in connection with the complexity of the experimental determination of the kinetics of stress development in the coating-base composite. Originality. The authors of this work, on the basis of the first created mathematical model and software product Mathcad-Prime 6 2020, conducted a study of the level and principles of the formation of residual stresses in the coating during gas-thermal layer-by-layer spraying with various material, including the possibility of using a pulsating spraying air flow. Analytical studies have shown that the attention in the literature over the past five to seven years has been paid only to the study of residual stresses and deformations in welded joints, and only the growing interest in spraying technology opens up wide possibilities for studying the formation of stress fields in a thermal gas coating. Practical relevance. The results obtained in this paper confirm the formation of residual stresses in coatings and can be used as computational programs to solve design tasks, as well as for educational purposes during experts training in engineering fields.

Published: December 2020

Purpose. Development of CFD model to evaluate the efficiency of wastewater treatment in a horizontal settler. The CFD model can be used to calculate flow hydrodynamics and mass transfer in settlers with complex geometric shape in the area of wastewater flow. Methodology. For numerical simulation of the process of wastewater movement in a horizontal settler, two mathematical models are used. The first model is based on the motion equations of a viscous incompressible fluid – the Navier-Stokes equations. The Navier-Stokes equations are written in the variables «vorticity - flow function». A two-dimensional mass transfer equation is used to calculate the concentration of a pollutant in a horizontal settler. To numerically integrate the two-dimensional mass transfer equation, a finite-difference splitting scheme is used. The splitting of the modeling equation of mass transfer is carried out so that at each fractional step to determine the unknown value of the pollutant concentration by an explicit formula. For numerical integration of the vortex transfer equation and the equation for the flow function (the Navier-Stokes system of equations), finite-difference splitting schemes are used. Findings. Based on the developed CFD model, a complex of computer programs has been developed, which makes it possible to determine the efficiency of water treatment in a horizontal settler with additional elements. The results of a computational experiment to assess the efficiency of water treatment in a horizontal settler with additional elements in the form of plates are presented. Originality. An efficient CFD model has been created, which allows to quickly evaluate the efficiency of wastewater treatment in a horizontal settler with additional elements. The developed CFD model takes into account the geometric shape of the facility and the most significant physical factors, that influence the efficiency of the waste water treatment in horizontal settler: non-uniform flow velocity, diffusion, different position of inlet and outlet openings. Practical value. The developed CFD model belongs to the class of «diagnostic models» and can be used to assess the efficiency of treatment facilities at the stage of their preliminary design.
Social Contradictions in Thessalonica during the Ottoman Siege of 1422–1430
Authors: Zhigalova Natalia E.
Published: December 2020

This article analyses social contradictions within the urban community of Thessalonica during the Ottoman siege between 1422 and 1430. Also, the author considers the issue of relations between the population and the city administration of Thessalonica in the conditions of economic crisis and political instability caused by the fact that the city was under siege. The study demonstrates that one of the destabilising factors of the urban society was the townspeople’s complete disappointment with Andronikos Palaiologos, the governor of the city. The unpopular measures taken by the despot to organise the defense of the city against the Ottoman army approaching in 1422 led to intra-city unrest and riots. Realising that the current government was not able to protect them from external threats or guarantee their stability in the future, the inhabitants of Thessalonica turned to those who were interested in the normal functioning of the city and had the resources for it, i.e. the Turks and Venetians. It is revealed that the supporters of the pro-Turkish opposition were representatives of the urban aristocracy who, during the Ottoman rule in Thessalonica between 1387 and 1402, strengthened their position by collaborating with the Ottoman administration and probably lost some of their powers and privileges after the return of Thessalonica under Byzantine rule. In turn, in 1423, members of the city council representing the real political power of the city and no longer subordinate to the imperial governor, transferred Thessalonica under the rule of the Venetian Republic, hoping to preserve their status and position. The polarisation of the urban community led to the fact that part of the aristocracy, especially the pro-Ottoman, fled from the city or was arrested, and ordinary townspeople were defenseless against the challenges that the Venetian rule in Thessalonica brought with it.

Published: December 2020

To solve the problems concerning moisture behaviour in the material of construction’s enclosure, especially at alternating temperatures, is very important for the correct calculations of resistance to heat conduction of construction’s enclosure and, ultimately, for comfortable living conditions. However, there are still no methods for building enclosure’s materials that could determine the temperature of moisture crystallization in the material in solid phase. The premise of the research is that water incoming to the material of construction’s enclosure, presenting in the construction’s material in the form of oxides and salts, as a result of hydrolysis process of some elements, is an eutectic solution with unstable composition and concentration. Thus, the research of moisture crystallization process transfers from micro- area (when determining the temperature of crystallization by the size of material’s pores) to the nano- area when researching the eutectic solution at the possible condition of hydrates formation. The experimental technique was developed to perform laboratory research of the process of moisture freezing. The technique takes into account that freeze-thaw process of moisture in solid body is studied at significant difference between mass of liquid phase and mass of solid phase. The method was simplified for the broad use at working conditions. The simplicity of the method aimed at obtaining experimental resultsis compensated by the developed mathematical method of processing the results of the research. Mathematical solution of the problem based on the comparison of freezing curves behaviour of the samples in dry and humidified samples. Apart from the temperature of moisture freezing, the developed method allowed obtaining additional characteristics of moisture states, such as amount of unfrozen moisture in construction’s material, supercooling temperature, heat capacity of moisture in liquid and solid states, concentration of dissolved agents. Knowing the concentration of dissolved agents in the material, even without knowing the exact composition of these agents, allows manipulating the temperature of moisture freezing at the nanotechnology level.

In the areas of construction materials science, the most promising solution is a set of issues related to the study of the influence of conditions for the formation of the material structure, including the possibilities of its self-organization, on its properties. The chemical and physical aspects of this influence are studied at the micro level, using the entire complex of “subtle” studies. At the same time, there are methods that allow us to assess the possibility of nanoeffects in experiments carried out at the macro level: in production or in the laboratory. One of these methods is the method described in the article. The main provisions of the methodology have been formed on the basis of statistical methods for conducting experiments and studying technological processes. This technique can significantly reduce the number of experiments performed while maintaining the adequacy of the results obtained and makes it possible to perform further analytical optimization of the results and their engineering interpretation. In particular, application of this technique allows evaluating joint influence of various factors on the result, that makes it possible to identify synergistic and antagonistic effects and then test them at the micro level by studying the nanostructure of materials. The article, as an example, considers the technology of concrete, focused on the utilization of concrete scrap as a filler or filler in building materials for various purposes. The results of research on the development of composite binder compositions based on fine-ground concrete scrap waste, mineral binder, synthetic fibers and polymers cured as a result of chemical interaction with the components of the concrete mixture are presented. This binder can be used for making various wall elements of buildings.

Une histoire de l’exploitation laitière : approches génétique, archéozoologique et biomoléculaire
Authors: Roffet-Salque Mélanie , Gerbault Pascale , Gillis Rosalind E.
Published: December 2020

Le lait a une place importante dans le régime alimentaire d’un certain nombre de nos sociétés
modernes, en particulier sur le continent européen. Pourtant, le lait n’est entré dans notre régime alimentaire
que tardivement. En effet, ce n’est qu’avec la domestication des bovins, brebis et chèvres il y a plus
de 10 000 ans, que l’homme a commencé à consommer du lait. Le lait frais est riche en lactose, le « sucre
du lait », et sa consommation par des individus qui y sont intolérants peut provoquer des troubles digestifs.
Pourtant, de nos jours, un adulte sur trois dans le monde peut digérer le lactose grâce à la production de
l’enzyme lactase permettant l’hydrolyse du lactose en glucose et galactose. En Europe, la production de
lactase à l’âge adulte est due à une seule mutation (-13910*T) dans le génome humain. Cette adaptation
à la consommation de lait frais depuis la Préhistoire suggère une pression de sélection forte dans la population
européenne. Tandis que l’analyse d’ADN ancien d’individus du début du Néolithique n’a pas permis de
détecter cet allèle, il apparaît chez une proportion plus importante d’individus plusieurs millénaires après la
domestication des bovins et caprinés. Outre les analyses génétiques permettant de détecter si les premiers
agriculteurs avaient la capacité de digérer le lactose, la problématique de l’exploitation du lait pendant la
préhistoire peut être abordée à partir des restes des animaux domestiques. L’étude des ossements animaux
découverts sur les sites archéologiques permet d’avoir accès aux stratégies d’abattage des bovins et caprinés,
et donc à la gestion démographique des troupeaux. Les courbes d’abattage ont permis de montrer que les
caprinés étaient exploités pour leur lait dès le Néolithique précéramique. D’autres méthodes complémentaires
des courbes d’abattage, les analyses isotopiques des restes dentaires animaux (bovins et caprinés),
permettent d’établir la saisonnalité des naissances et l’âge au sevrage. Bien que relativement récentes, ces
études ont déjà montré un sevrage précoce des veaux dans certains sites néolithiques, probablement en lien
avec une durée de lactation plus courte chez les vaches néolithiques. L’étude de tessons de poterie est aussi
un champ d’investigation précieux pour examiner les débuts de l’exploitation laitière. L’identification de
lipides issus de lait dans des poteries du VIIe millénaire a permis de montrer que le lait était bien une
denrée alimentaire au Proche-Orient. De même, la présence de résidus laitiers dans des récipients perforés
découverts dans des sites archéologiques du début du Ve millénaire a permis d’identifier la production
de fromages. Les approches génétique, archéozoologique et biomoléculaire restent complémentaires pour
élucider les débuts de l’histoire de l’exploitation laitière.
Cycle de reproduction des ovins et rythme saisonnier de l’élevage : un schéma plurimillénaire bouleversé par la recherche agronomique
Authors: Balasse Marie , Keller Matthieu , Balasescu Adrian , Tresset Anne , Chemineau Philippe
Published: December 2020

Ovins et caprins connaissent au cours de l’année des périodes de fertilité et d’infertilité pesant
fortement sur les élevages, avec des conséquences sur l’organisation du travail et la disponibilité des
productions. Des recherches visant à contrôler et maîtriser la reproduction des petits ruminants sont développées
afin de s’affranchir de ces contraintes saisonnières. Elles portent actuellement sur l’utilisation des
signaux socio-sexuels, comme une alternative aux traitements lumineux et hormonaux largement utilisés
par les agriculteurs pour induire et synchroniser l’ovulation des femelles, mais présentant des problèmes sanitaires,
environnementaux et sociétaux. « L’effet mâle », qui consiste en la réactivation de l’ovulation suite
à l’introduction d’un mâle parmi des femelles en repos sexuel, est incontestablement une solution d’avenir
intéressante pour la transformation des élevages actuels vers l’utilisation de techniques moins coûteuses,
sans incidence sur l’environnement et favorisant le bien-être animal. En poursuivant l’objectif d’extraire
l’éleveur de cette contrainte saisonnière, la recherche agronomique révolutionne un schéma millénaire. Plus
de 10 500 ans nous séparent des premiers moutons domestiques. Le caractère saisonnier des naissances
a pu peser fortement sur les élevages préhistoriques. Précisément, qu’en était-il ? L’archéozoologie est en
mesure d’écrire cette histoire : elle utilise la biogéochimie isotopique pour lire dans les dents des animaux
une information relative à leur saison de naissance. L’état des connaissances sur les moutons européens
du VIe au IIIe millénaire avant notre ère confirme des naissances saisonnées, survenant sur 3 à 4 mois,
plus tardivement aux latitudes élevées (59°N) qu’aux latitudes moyennes (43 à 48°N). La poursuite de cette
recherche devrait permettre de renforcer ces schémas globaux contraints par l’environnement, et de préciser
une variabilité imputable à des choix techniques. En décrivant cette trajectoire depuis les premiers temps
de la domestication, l’archéozoologie replace la recherche agronomique dans une perspective de très longue
durée. En outre, elle aidera peut-être à comprendre pourquoi la domestication a atténué mais n’a pas réussi
à faire disparaître le saisonnement physiologique de la reproduction chez les ovins domestiques.
Paléo-imagerie par rayons X : une méthode d’exploration transdisciplinaire, de l’archéologie à la chirurgie Hélène
Authors: Coqueugniot Hélène
Published: December 2020

L’imagerie par rayons X, bi- et tridimensionnelle, est devenue une méthodologie incontournable
dans de nombreux champs disciplinaires dont celui des sciences archéologiques. Contrairement aux autres
méthodes d’imagerie permettant seulement des acquisitions de surface (photographie et photogrammétrie,
scanner laser), le rayonnement X permet également des acquisitions de volume, ce qui s’avère être un
avantage fondamental dans les indications nécessitant de visualiser du contenu sans toucher au contenant.
Cette propriété physique du rayonnement X de traverser la matière et de révéler l’intérieur des objets sur
des images projetées en 2 dimensions a été appliquée très tôt au domaine archéologique, dès l’invention
même de la radiologie en 1895, en parallèle avec son développement fulgurant dans le domaine médical.
Les applications « archéométriques » des rayons X ont fait émerger le terme de paléoradiologie, qui définit
l’application du rayonnement X à l’étude de matériaux bio-archéologiques.
Un siècle après, les méthodes d’acquisition par rayons X se sont considérablement développées (radiologie
numérique, tomodensitométrie, microtomographie RX) et le traitement des images a ouvert l’accès, grâce
à la révolution numérique, à une nouvelle dimension. L’introduction de cette troisième dimension pour
l’imagerie radiologique a permis de nombreuses avancées en recherches fondamentale et appliquée dans le
domaine archéologique, tout en renouvelant considérablement les possibilités de conservation et de valorisation
du patrimoine. En constituant un réseau interdisciplinaire, nous avons développé, à partir de la
tomodensitométrie, une chaîne complète d’imagerie tridimensionnelle, initiée pour l’anthropologie biologique
et qui trouve ses applications dans le domaine de l’archéologie et plus récemment dans celui de la
chirurgie reconstructrice.
En parallèle avec l’utilisation des rayons X, d’autres méthodes d’acquisitions d’images apportent également
leurs contributions à l’archéologie. Leur intégration dans une approche transdisciplinaire utilisant
l’ensemble des modalités non-destructives d’acquisition d’images et de leur représentation (multimodale et
multidimensionnelle) a été nommée paléo-imagerie. La paléo-imagerie s’exprime à la fois sur le terrain et en
laboratoire, fonctionne de manière diachronique (sans focus chronologique, de la préhistoire aux périodes
contemporaines) et holistique en contextualisant l’objet dans son environnement archéologique. Dans cette
optique, la paléo-imagerie a toute sa place au sein des méthodes de l’archéométrie

The analyses conducted showed that the scale consisted of 40 items under a single factor which explained 61.179% of the total variance, and the Cronbach’s Alpha value calculated to examine the reliability of the scale was .98. In conclusion, analyses conducted to examine the reliability and the validity of the Social Networking Literacy Scale (SNLS) show that it is an efficient measurement tool to assess social networking literacy levels of the individuals.
“CONSTRUCTIVE EXPRESSIONISM” BY EVGENIA TOLMASHOVA
Authors:   Siberian Federal University (Krasnoyarsk, Russian Federation), Serikova Tatiana Yu.
Published: December 2020

The relevance of the research topic is conditioned by the need to search for new interdisciplinary approaches to the problem of cognition of the world. The degree of scientific development of the subject covers the period from antiquity to modern times. Vasilyeva E.V., Khazieva E.V., Petrenko Yu.A., Shatilov S.F., Stoletov A.I. actively works on the problem of subjective reality. It should also be noted that the works devoted directly and directly to the study of subjective re-ality within the framework of the existence of a work of art exist relatively few in comparison with studies of other aspects of art. The object of research is the current issues of cognition of the world order. As the subject of re-search, the subjective reality that the author creates in the space of a work of art is chosen. The study is based on the material of the paintings of the Krasnoyarsk painter Tolmashov (1966–2014). The aim of the research is to reveal the essence, specificity and ways of forming subjective reali-ty in a work of art. In accordance with the purpose of the study, the following tasks are set: to deter-mine the motivation and principles of constructing a sub-reality in a work of fine art. The basis of the methodological base was laid as general scientific principles, as well as special art research methods, including: formal-stylistic, iconographic and structural. When working on the study, the determining method was a method of scientific cognition as an interpretation that allows us to reveal the principles of the construction and existence of subjective reality. Structural-functional and dialectical methods are also used. The empirical basis of the study is the experience of studying the paintings of the Krasnoyarsk artist E.N. Tolmashova. The scientific novelty of the research consists in the following statement: the subjective of reality in pictorial works is conditioned by the desire of the author of the work through the experimental con-struction of new, not previously existed realities, to understand the structure of objective reality exist-ing in addition to his consciousness. The obtained conclusions and generalizations of the basic principles of subjective of objective reality in a work of fine art can be used in the analysis of artistic creativity as a way of constructing an analog model of the world order. Also it should be said that the work of E.N. Tolmashova is not well studied in art history. The scientific material has been introduced not previously studied material, allowing expanding the under-standing of the art of painting in Siberia, as well as the trends and forms of its development at the turn of the XX and XXI century. The materials of the research were used in lecturing and conducting seminars on the discipline “Art culture of Siberia”, which is basic for the preparation of bachelors on specialty 54.03.01. The training was conducted on the basis of the Siberian Federal University.

Moreover, the article presents information about the peculiarities of the organization of museum institutions of nature reserves and national parks of this region. In addi-tion, the authors use specific examples of actualizing the natural heritage through its museumification. Besides, the author emphasizes that the uniqueness of the museum business of the reserved areas of the Trans-Baikal Territory is expressed in the unified information visit center “Specially Protected Natural Territories of Transbaikalia”, established in 2012, located in Chita. It provides all information to tou-rists about all nature protection zones of the region, as well as conducts various activities for the for-mation of ecological culture. The author draws our attention to the fact that today many exhibits of specially protected natural areas have stopped demonstrating taxidermy exhibits, because stuffed animals have a negative impact on people, causing negative associations related to the killing of the animal, so many visitor centers replaced with mock-ups. One of the important positive qualities of museums and visiting centers of specially protected natural territories is their ability not only to satisfy the recreational needs of visi-tors, but also to have a significant educational potential. Despite the fact that today the protected natu-ral areas of the region under discussion do not have museums recreating or creating new ones, they suggest perspective plans for the departments of environmental education. In conclusion, the nature of museums and visiting centers in nature reserves are presented, both positive and problematic moments in their formation and activities are indicated.
