Improved Iterative Solution of Linear Fredholm Integral Equations of Second Kind via Inverse-Free Iterative Schemes
Authors: Gutiérrez José Manuel , Hernández-Verón Miguel Ángel , Martínez Eulalia
Published: October 2020

This work is devoted to Fredholm integral equations of second kind with non-separable kernels. Our strategy is to approximate the non-separable kernel by using an adequate Taylor’s development. Then, we adapt an already known technique used for separable kernels to our case. First, we study the local convergence of the proposed iterative scheme, so we obtain a ball of starting points around the solution. Then, we complete the theoretical study with the semilocal convergence analysis, that allow us to obtain the domain of existence for the solution in terms of the starting point. In this case, the existence of a solution is deduced. Finally, we illustrate this study with some numerical experiments.
Efficient k-Step Linear Block Methods to Solve Second Order Initial Value Problems Directly
Authors: Ramos Higinio , Jator Samuel N. , Modebei Mark I.
Published: October 2020

There are dozens of block methods in literature intended for solving second order initial-value problems. This article aimed at the analysis of the efficiency of k-step block methods for directly solving general second-order initial-value problems. Each of these methods consists of a set of 2k multi-step formulas (although we will see that this number can be reduced to k+1 in case of a special equation) that provides approximate solutions at k grid points at once. The usual way to obtain these formulas is by using collocation and interpolation at different points, which are not all necessarily in the mesh (it may also be considered intra-step or off-step points). An important issue is that for each k, all of them are essentially the same method, although they can adopt different formulations. Nevertheless, the performance of those formulations is not the same. The analysis of the methods presented give some clues as how to select the most appropriate ones in terms of computational efficiency. The numerical experiments show that using the proposed formulations, the computing time can be reduced to less than half.

Accumulative alcohol hangovers cause liver damage through oxidative and inflammatory stress. Numerous antioxidant and anti-inflammatory reagents have been developed to reduce alcohol hangovers, but these reagents are still insignificant and have limitations in that they can cause liver toxicity. Oyster hydrolysate (OH), another reagent that has antioxidant and anti-inflammatory activity, is a product extracted through an enzymatic hydrolysis process from oysters (Crassostrea gigas), which can be easily eaten in meals. This study was aimed at determining the effects of OH on alcohol metabolism, using a single high dose of ethanol (EtOH) administered to rodents, by monitoring alcohol metabolic enzymes, oxidative stress signals, and inflammatory mediators. The effect of tyrosine-alanine (YA) peptide, a main component of OH, on EtOH metabolism was also identified. In vitro experiments showed that OH pretreatment inhibited EtOH-induced cell death, oxidative stress, and inflammation in liver cells and macrophages. In vivo experiments showed that OH and YA pre-administration increased alcohol dehydrogenase, aldehyde dehydrogenase, and catalase activity in EtOH binge treatment. In addition, OH pre-administration alleviated CYP2E1 activity, ROS production, apoptotic signals, and inflammatory mediators in liver tissues. These results showed that OH and YA enhanced EtOH metabolism and had a protective effect against acute alcohol liver damage. Our findings offer new insights into a single high dose of EtOH drinking and suggest that OH and YA could be used as potential marine functional foods to prevent acute alcohol-induced liver damage.
The Effect of Material Properties on the Accuracy of Superplastic Tensile Test
Authors: Aksenov Sergey , Mikolaenko Vadim
Published: October 2020

Tensile testing is widely used for the mechanical characterization of materials subjected to superplastic deformation. At the same time, it is known that the obtained flow data are affected by specimen geometry. Thus, they characterize the specimen rather than the material. This work provides the numerical analysis aimed to study how the material flow behavior affects the results of tensile tests. The simulations were performed by the finite element method in Abaqus software, utilizing user-defined procedures for calculation of forces acting on the crossheads. The accuracy of tensile testing is evaluated by the difference between the input material flow behavior specified in the simulations and the output one, obtained by the standard ASTM E2448 procedure based on the predicted forces. The results revealed that the accuracy of the superplastic tensile test is affected by the material properties. Even if the material flow behavior follows the Backofen power law, which is invariant for the effective strain, the output stress–strain curves demonstrate significant strain hardening and softening effects. The relation between the basic superplastic characteristics and the tensile test errors is described and analyzed.
Sphingopyxis sp. Strain OPL5, an Isoprene-Degrading Bacterium from the Sphingomonadaceae Family Isolated from Oil Palm Leaves
Authors: Larke-Mejía Nasmille L. , Carrión Ornella , Crombie Andrew T. , McGenity Terry J. , Murrell J. Colin
Published: October 2020

The volatile secondary metabolite, isoprene, is released by trees to the atmosphere in enormous quantities, where it has important effects on air quality and climate. Oil palm trees, one of the highest isoprene emitters, are increasingly dominating agroforestry over large areas of Asia, with associated uncertainties over their effects on climate. Microbes capable of using isoprene as a source of carbon for growth have been identified in soils and in the tree phyllosphere, and most are members of the Actinobacteria. Here, we used DNA stable isotope probing to identify the isoprene-degrading bacteria associated with oil palm leaves and inhabiting the surrounding soil. Among the most abundant isoprene degraders of the leaf-associated community were members of the Sphingomonadales, although no representatives of this order were previously known to degrade isoprene. Informed by these data, we obtained representatives of the most abundant isoprene degraders in enrichments, including Sphingopyxis strain OPL5 (Sphingomonadales), able to grow on isoprene as the sole source of carbon and energy. Sequencing of the genome of strain OPL5, as well as a novel Gordonia strain, confirmed their pathways of isoprene degradation and broadened our knowledge of the genetic and taxonomic diversity of this important bacterial trait.

Published: October 2020

Soil salinity is one of the most important abiotic stresses limiting plant growth and productivity. The breeding of salt-tolerant wheat cultivars has substantially relieved the adverse effects of salt stress. Complementing these cultivars with growth-promoting microbes has the potential to stimulate and further enhance their salt tolerance. In this study, two fungal isolates, Th4 and Th6, and one bacterial isolate, C7, were isolated. The phylogenetic analyses suggested that these isolates were closely related to Trichoderma yunnanense, Trichoderma afroharzianum, and Bacillus licheniformis, respectively. These isolates produced indole-3-acetic acid (IAA) under salt stress (200 mM). The abilities of these isolates to enhance salt tolerance were investigated by seed coatings on salt-sensitive and salt-tolerant wheat cultivars. Salt stress (S), cultivar (C), and microbial treatment (M) significantly affected water use efficiency. The interaction effect of M x S significantly correlated with all photosynthetic parameters investigated. Treatments with Trichoderma isolates enhanced net photosynthesis, water use efficiency and biomass production. Principal component analysis revealed that the influences of microbial isolates on the photosynthetic parameters of the different wheat cultivars differed substantially. This study illustrated that Trichoderma isolates enhance the growth of wheat under salt stress and demonstrated the potential of using these isolates as plant biostimulants.

The identification of microorganisms in closely related groups is challenging. The present work focused on the different molecular methodology for the accurate microbial identification in the five commercially available organic agriculture materials enriched with effective microorganisms. From the tested five organic agricultural materials, a total of seven distinct bacterial colonies (A-1, B-1, C-1, D-1, E-1, E-2, and E-3) were isolated and processed for sequential identification utilizing HiCrome™ Bacillus agar, biochemical tests with API CHB50, 16S rRNA gene analysis, random amplified polymorphic DNA (RAPD), and species-specific PCR analysis. All the isolated microorganisms were Gram-positive rods and spore former belonging to Bacillus group and appeared as a differential characteristic feature on HiCrome™ Bacillus agar. All isolates showed high-percentage similarities with the different members of Bacillus species in biochemical testing and 16S rRNA gene analysis. The collective identification results revealed isolates, A-1, B-1, and C-1, close to B. velezensis. Further RAPD-PCR and species-specific PCR discriminated and provided confirmatory evidence for D-1 as B. thuringiensis and E-1, E-2, and E-3 as B. licheniformis, respectively. In addition, presence of B. thuringiensis was also confirmed by toxin crystal protein staining. In conclusion, the species-specific primers could be used as a rapid and accurate identification tool to discriminate closely related Bacillus species such as B. subtilis, B. licheniformis, and B. thuringiensis.

Published: October 2020

Relevance. Underestimating the importance of economic analysis is the barrier to the implementation of cariesprevention programs.

The aim is to study with use of mathematic modeling method the clinical and economic effectiveness of dental caries prevention programs provided for schoolchildren.

Materials and methods. The method of mathematic modeling was used to evaluate the clinical and economic efficiency of the caries prevention programs (educational, fissure sealing, fluoride varnish). The cost of prevention program implementation and the expenses for caries treatment without prevention were calculated according to the rate of Volgograd territorial mandatory medical insurance Fund for 2018 year. The differences between the caries prevention program’s cost and the expenses needed for the treatment of “prevented caries” were considered as saving.

Results. It was revealed that the Educational Dental Program for the first grade schoolchildren has short duration (2 years) of clinical-economic efficiency. The Continuous Educational Dental Program applied for 6 years by dental hygienists or dentists led to saving (per 100 children) of 99.5-115.0 or 84.0-99.6 thousand roubles respectively. The economic effect of The First Permanent Molar Fissure Sealing Program was revealed after 2 years only when The Program was implemented by dental hygienists. After 6 years of working with this Program the saving were 181.3 or 146.2 thousand roubles per 100 children depending on who implemented the Program, dental hygienists or dentists. The cost of Fluoride Varnish Program implementation was higher than the treatment of “prevented caries”. However, the number of “prevented caries” after fluoride varnish application is higher than after the implementation of the Educational Dental Programs. Moreover, fluoride varnish, in contrast to fissure sealing, prevents caries of smooth surfaces of permanent teeth.

 

Conclusions. The method of mathematic modeling can be used for the development of the caries prevention programs in various regions considering the availability of personnel and financial resources, and for evaluation of the clinical and economic effectiveness of preventive programs implementation.
Indicators of permanent teeth eruption in children of Tashkent city and comparative assessment with the data of peers of different Russian cities
Authors: Kamilova R. T. , Kamilov J. A.
Published: October 2020

Relevance. Characteristics of eruption of secondary teeth is of diagnostic and prognostic interest, is the basis for implementation of targeted therapeutic and preventive measures among children. No research has ever been carried out in Uzbekistan to study an age and gender regional features of secondary teeth eruption. The aim is to determine the timing and symmetry of secondary teeth eruption in children of the city of Tashkent of the Republic of Uzbekistan and comparative assessment with the children of different cities of Russia.

Materials and methods. 3,834 children between 3 and 17 years were conducted dental examination. A comparative analysis was made of the initial, intermediate and final periods of eruption of secondary teeth for children of Uzbekistan (Tashkent city) and Russia (Saratov, Izhevsk and Sergach).

Results. In Tashkent children of both gender, in most cases, lower teeth were erupted before than their antagonists. In girls, teeth were erupted earlier than their male counterparts. At the initial stage of eruption, asymmetry was more pronounced in boys than in girls, while in the middle and final stages it was more pronounced in the opposite direction. Observed asymmetry of antimere’s teeth were indicated left-handed permanent dentition in boys and right-handed in girls. Children of Tashkent city were observed permanent dentition in one group of teeth 1-16 months earlier, and in others – 1-24 months later than their peers in Russian cities. Revealed differences were more pronounced among boys than among girls. Children in Tashkent differed more from their peers in Sergach and less from those in Izhevsk.

 

Conclusions. Regional peculiarities of permanent dentition in children of Tashkent city and revealed expressed differences with indicators of Russian children are the basis for development of separate age and  gender normative assessment permanent dentition tables for children of Uzbekistan.
Diagnosis of early forms of dental caries in а primary school children
Authors: Avraamova O. G. , Kalashnikova N. P. , Goryacheva V. V. , Kulazhenko T. V.
Published: October 2020

Relevance. At present the question of finding and applying effective methods and approaches for diagnosing early manifestations of dental caries in the form of foci of demineralization during eruption of  permanent teeth in children remains an important and relevant issue. Timely diagnosis at the age of 6-7 years prevents the transition of the initial forms of caries into carious defects and further excludes the use of invasive methods of surgical recovery treatment. The aim is improving the approach of caries diagnostics approach by identifying foci of demineralization and hidden carious cavities in children during teething of permanent teeth.

Materials and methods. An epidemiological examination of 380 children in Moscow aged 6-7 years was carried out. Of the total number of children examined by the method of randomization 150 people were selected, which are divided into 3 groups depending on the intensity of caries. Children of each group were diagnosed with caries using various diagnostic methods – visual inspection, vital staining, hardware method (Estus-LED-Alladin Multicolor (Geosoft, Russia).

Results. In children 6-7 years of age in Moscow, the average prevalence and intensity of caries was established. However, the epidemiological examination does not take into account the number of foci of demineralization and hidden carious cavities, which can subsequently be transformed into destructive forms and cause an increase in caries. This indicates the need to improve the diagnostic approach using different methods for identifying early forms of caries. When using the hardware method, a greater number of foci of demineralization and hidden carious cavities were revealed on all surfaces of permanent teeth. There was a tendency to an increase in the number of foci of demineralization and hidden carious cavities depending on the intensity of caries.

Conclusions. The effectiveness of the hardware method in the group of children DMF = 0 was 40,9% in comparison with the visual method and 36,4% in comparison with vital staining; with DMF = 1-2 – 35,4% in comparison with other methods, with DMF ≥ 3 – 43.3% in comparison with the visual and 40% in comparison with the vital. Diagnosis of early forms of caries made it possible to prescribe treatment and preventive measures in a timely manner and further reduce the growth of caries.

Authors: Ayupova F. S. , Alekseenko S. N. , Zobenko V. Ya. , Gayvoronskaya T. V.
Published: October 2020

Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.

Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.

Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. 

Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.
ON THE MAJOR TURNAROUND IN THE EAST FRONT OF WORLD WAR II (according to memoirs of German and Soviet military commanders)
Authors: Belov Andrei M.
Published: October 2020

The author refers in the article to such an important aspect of the major turnaround in the East Front of the Second World War as mastering the combat experience of contemporary warfare, based on the memoirs of German and Soviet military
commanders. The author concludes that if, at the initial stage, Germany’s sudden attack on the USSR and the use of a large mass of tanks and aircraft in combat led the Wehrmacht to success, by the end of 1941, the Red Army’s victory near Moscow
had defi ned a turnaround in the war. The Red Army endured the worst challenges of the initial stage and began to master the methods of conducting contemporary war by Soviet military commanders. Of those commanders who advanced in the future, there were those military commanders who asserted themselves in the battles of Moscow and Stalingrad. Contemporary war required them to master the experience of guiding a large mass of equipment – tanks, aircraft – in accordance with the potential embedded in them. The formation of tank, aviation divisions, corps, armies laid the material foundation for the major turnaround in the war. The ability to anticipate the actions of the enemy and make decisions unexpected to it had become an essential component of the commanders’ experience. The experience of coordinating the actions of different fronts and branches of troops, the formation of armies possessing the latest ammunition, the proper provision with arms and other materials became the guarantee of victory around Stalingrad and Kursk, the liberation of the Ukraine on the left bank of the Dnieper and of Donbass, that is, the victories considered to be the major turnaround in the Second World War.
SOURCE-HISTORIOGRAPHICAL STUDY OF THE EXISTENCE OF THE SECOND KOSTROMA KREMLIN (Article 2)
Authors: Kabatov Sergey A. , Kabatova Yelena A.
Published: October 2020

The question of dating an urban settlement, if its date has no clear or specific written confirmation, is always very problematic and complicated. Its solution requires the use of the widest possible range of data. This research is presented in
a block of articles that attempt to cover the source-historiographical study of the existence of the second Kostroma Kremlin, including the latest archaeological data from 2016-2017 on the territory of the Old city of the second Kostroma Kremlin. The study raises questions about the conditions, specifics and dating of the foundation of the first and second Kostroma Kremlins, their nature of development, the conditions for obtaining the icon Our Lady of Saint Theodore in Kostroma and its storage location in both Kremlins. The question of the place, time and conditions of the construction of the Assumption Cathedral is considered separately, since only research on the conditions and dating of its construction can shed light on the date of the foundation of the Old city of the second Kostroma Kremlin. Article 2 continues this block of research, which refers us to the time and conditions of building the Dormition Cathedral.

Authors: Kamygina Galina A.
Published: October 2020

The activity of jewellery and art artels during the War is almost not covered in Soviet historiography because of the specifi cs of this industry. The proposed article analyses the change in the composition of jewellery artels of the Upper Volga region in the period of 1941-1945. The contribution of cooperatives to the supply of clothing to the Red Army is examined. Particular attention is paid to providing civilians with such specifi c goods as jewellery and art products. To study this issue, little-studied archival sources were used; some of them were declassifi ed only recently. In general, the products of jewellery
cooperatives of the Upper Volga region during World War II can be divided into several groups: 1. Items that continued the tradition of local art crafts: jewellery and art products (earrings, brooches, cigarette cases, decoration buttons, etc.) 2. Metal haberdashery: metal dishes, metal pads on bags and briefcases, etc. 3. Military products: insignia and buttons for military uniforms, parts for gas masks and parachutes, medical equipment.
PANEGYRIC TRADITIONS IN RUSSIAN LITERATURE OF THE 18TH CENTURY, PRECEDING THE FORMATION OF GAVRILA DERZHAVIN’S BATTLE ODE
Authors: Ratnikov Aleksandr N.
Published: October 2020

Gavrila Derzhavin’s creative work marked an important stage in the formation of Russian poetry. Raised in the works of previous generations of poets, Gavrila Derzhavin mastered the best samples of Russian and foreign solemn panegyric works, creating on their basis a special form of his own batal ode. What contributes to a full and deep understanding of the process of formation and development of Gavrila Derzhavin’s batal lyrics, is a study of the conception of the Russian odic tradition related to the time of Peter I. The place of poetry in the life of society had been rethought during this period; poetry had been rationalised at the service of the state. Poetry texts started to be used as musical and poetry accompaniment of holidays, solemn meetings of reigning persons or praise of military successes. Russian literature responded to this request by the appearance of various samples of solemn, panegyric poetry - cantos and other solemn poems. During the reign of Peter I, who were the most prominent representatives of the panegyric lyrics were Theophan Prokopovich (1681–1736), Stefan
Yavorsky (1658–1722) and Dmitri Rostovsky (1651–1709). The chosen batal works of the above-mentioned authors as well as the batal lyrical poetry by Gavrila Derzhavin are the subject of research within the framework of this article. The numerous
correspondences and elements of continuity between the panegyric cantos and the odes by Gavrila Derzhavin expressed in a similar system of allegorical image-symbols, as well as in orientation to antique specimens and to biblical motifs, are revealed in the comparative study of solemn panegyric works of batal subject matter and the batal ode of Gavrila Derzhavin.
THE PEASANT WORLD IN THE PRE-REVOLUTIONARY SHORT STORIES BY IVAN KASATKIN
Authors: Meshalkin Aleksandr N.
Published: October 2020

The article examines the pre-revolutionary small prose of Ivan Kasatkin. It explores the social and moral dimensions of his stories, the individual features of his depiction of the life of Kostroma peasants in the turbulent years before the Russian
Revolution of 1917. Ivan Kasatkin, a peasant born himself, offers an unprejudiced, realistic view of Kostroma fellas at the time, of their complex and contradictory world in all its entirety. In his opinion, the inertness and cruelty of male peasants
has social roots, as this is the period when a fella is forced to live the life of a destitute, deprived of basic human rights and utterly humiliated. In this way, Ivan Kasatkin follows in the footsteps of his predecessors, known as Democrat-Writers, such as Nikolai Uspensky, Vasily Sleptsov, Alexander Levitov, as well as his contemporaries, such as Ivan Bunin. At the same time, he makes his own unique contribution to the artistic study of the plight of peasants. He believes, for example, in the feasibility of revolutionary rejuvenescence of life, he believes in peasant happiness. Above all, socially acute stipulations of change are
manifest in his childhood narratives. The article focuses on the compositional features of the stories, namely, the use of the road motif, the use of contrast in the portrayal of people and nature, the use of symbolic imagery of forest and the Unzha River. The author argues that Ivan Kasatkin’s artistic approach, his poetics, enable him to convey the intensely poignant and morose atmosphere of living in rural central Russia on the eve of the Revolution, while pointing out the instinctive yearning of male peasants for the new, invigorating beginnings of life.
CREATIVE WORK OF ANTON CHEKHOV IN THE ASSESSMENT OF DMITRY FILOSOFOV
(based on reviews and articles of the 1900s)
Authors: Koptelova Nataliya G.
Published: October 2020

The article discusses the system of ratings, Anton Chekhov’s creative work, developed in the reviews and articles of Dmitry Filosofov of the 1900s. The features of his critical method, which were realised during this period, are characterised.
It is proved that Dmitry Filosofov perceives Anton Chekhov’s work as the artistic peak of Russian literature of the early 20th century and at the same time as a certain limit in its movement. It is noted that using the principle of «in occasion
of criticism» in his own way, he refracts the traditions of Vissarion Belinsky, Nikolay Dobrolyubov, Nikolay Chernyshevsky, Apollon Grigoryev. It is argued that the tendency to think in antinomies, manifested in the works of Dmitry Filosofov on
Anton Chekhov in the 1900s, connects him with Dmitry Merezhkovsky. An important role in the formation of philosophical assessments of Anton Chekhov’s creative work is played by the antinomies «Chekhov and Chekhovism», «Everyday tragedy and everyday heroism». They perform the function of bonds, connecting reviews and articles of this critic in a kind of «Chekhov» cycle. Dmitry Filosofov was one of the fi rst to use the antinomy «Chekhov and Chekhovism» in his works, which later became a constant in criticising the Fin de Siècle as a whole. Assessments of Anton Chekhov’s artistic heritage, concentrated in reviews and articles by Dmitry Filosofov of the 1900s, are focused on dialogue with statements by contemporaries – Dmitry Merezhkovsky, Zinaida Gippius, Vasily Rozanov. In an indirect form, they broadcast the ideas of building a «new religious consciousness». But at the same time, Dmitry Filosofov not only illustrates other people’s critical concepts, but also opens up new facets of Anton Chekhov’s work.
THE SPECIFICS OF METAPHYSICAL DEFAMILIARISATION IN SIGIZMUND KRZHIZHANOVSKY’S PROSE
Authors: Gorelov Oleg S.
Published: October 2020

The article analyses the creative work of Sigizmund Krzhizhanovsky with the help of a surrealist code. Associations with magic realism, with imaginism and partly with the literary nonsense naturally arise when considering the elements of the fantastic, the miraculous, the imaginary, the oneiric in Sigizmund Krzhizhanovsky’s aesthetic and artistic system. The surrealistic is present in the work of Sigizmund Krzhizhanovsky implicitly. At the external levels of the structure, the most
obvious signs of surrealist writing (nonlinear architectonics of the subject and the world, the representation of the desire of the unconscious, automatism, chains of «stupéfi ant images») either have a circumstantial nature or are not detected at all.
However, as shown in the article, those signifi cant elements that appear and are almost obsessively repeated in Sigizmund Krzhizhanovsky’s writing (minimal metaphysic defamiliarisation, framing, contemplation of the invisible, metonymic
parallax) can be called minimal surreal gestures. The article analyses the main features and specifi cs of the implementation of the metaphysic defamiliarisation, one of such gestures. This defamiliarisation is realised through complex work with space and time. The metaphysical is not beyond, but appears in this world, imperceptibly changing the perception of real objects, the atmosphere itself, drawing the subject into a strange mise-en-scène of nothingness, which does not violate the general specifi city and immanence of the landscape.
THE CONDITIONS FOR THE FORMATION OF THE SYSTEM OF THE RULE OF LAW IN RUSSIA
Authors: Grudinin Nikita S.
Published: October 2020

The article is devoted to the study of the conditions for the formation of a truly legal state in the Russian Federation. It is noted that the process of formation of the system of the rule of law requires signifi cant efforts both by the state and by
society. It is also emphasised that the key conditions that can ensure the effective functioning of the rule of law in Russia are the respect of the provisions of the Constitution of 1993 by citizens and the willingness to comply with those provisions in cooperation with the state, the independence of the judiciary, the real and rational separation of powers, the functioning of legislative bodies in accordance with the interests of citizens of the Russian Federation. According to the author’s opinion, trust in the Constitution and its ability to ensure social progress in general is the basis for strengthening the legal statehood of the Russian Federation in the long term. The author concludes that the strength of the construction of legal statehood in Russia is based on the stability of the constitutional system and the supremacy of the Constitution of the Russian Federation, its ability to subordinate to its action all citizens of the country and offi cials of public authorities.
THE REGIONAL ASPECT OF THE STUDY OF THE TRANSFORMATION
OF RUSSIAN SOCIETY IN THE 1950-1990S AND THE EVOLUTION OF THE ECONOMIC SYSTEM: REPRESENTATIVENESS AND UNIQUENESS OF THE UPPER VOLGA REGIONS OF THE LATE USSR
Authors: Nikiforov Yuriy S.
Published: October 2020

The article raises the question of opportunities, prospects and directions in studying the regional aspect of the problem of transformation of Russian society in the 1950-1990s and the evolution of the economic system in the late USSR. The theoretical
and methodological basis of the study is connected with the ideas of Mikhail Beznin and Tat’yana Dimoni on the formation of state capitalism in the late USSR; Alexei Yurchak’s, on the last Soviet generation. It is argued that the Upper Volga region (Vladimir, Ivanovo, Kostroma, Kalinin, Yaroslavl) of the late USSR as an object of historical research should be analysed simultaneously from two angles. On the one hand, it is indicated that these regions are suffi ciently typical and representative of the study of the late USSR in the political and socio-economic spheres. On the other hand, the uniqueness of the Upper Volga cluster of regions in terms of socio-cultural and mental characteristics, as well as geographical location, is emphasised. Particular attention is paid to the spatial localisation of the object of study. The role of the Upper Volga regions as large industrial and scientifi c-technical centres of Union-republican signifi cance, their importance in the militaryindustrial complex and the defence system of the USSR are examined. The formation of the infl uential layer of the political,
economic and scientifi c-technical elite in the studied regions is noted. The unique characteristics of the status of the Upper Volga regions as centres of Russian statehood and national, cultural identity (the Golden Ring of Russia tourist route), their
geographical proximity to Moscow are analysed.
PLANS OF THE NAZI LEADERSHIP OF THE THIRD REICH FOR THE OCCUPATION OF THE USSR
Authors: Volkov Grigoriy Yu.
Published: October 2020

The victory over the Axis powers had virtually preserved Russia in world history. It was a great celebration not only of the armed forces, but also of ideas. The article widely uses Soviet and modern publications, by both Russian and foreign scientists, dedicated to the East Front of World War II. The criminal essence of Adolf Hitler’s personality, his personal traits, way of thinking is shown, the analysis of his statements, offi cial speeches, private conversations, «table speeches», «Mein Kampf» is carried out. It also reconstructs the thinking process of other Nazi civil and military leaders who acted together with their Führer in pursuit of the common goal. The article for the fi rst time, taking into account the logic of thinking of the leadership of the third Reich, traces literally by years that the war against the USSR was conceived as a total genocide and carefully worked out in all directions. The author concludes that the bloody and inhuman logic of the leadership of the German Reich, big entrepreneurs and bankers, members of the National Socialist German Workers’ Party and the Schutzstaffel, generals and soldiers of the Wehrmacht, and a virtual legion of various offi cials clearly shows that they were all united in their desire to «stop Russian history».

Published: October 2020

When it attacked the USSR, Nazi Germany possessed signifi cant chemical weapons. Chemical support thus became one of the main kinds of operational (combat) support. Short-term course has been created for chemical service commanders and personnel chemical specialists training. The Red Army’s general attention was paid to the chemical defence measures, to eliminate the enemy manpower, weapons and military equipment by use of the fl amethrower and incendiary means, smoke screens were used to mask. Chemical detection and the prevention of chemical weapons use involved chemical, meteorological monitoring; chemical reconnaissance was provided mostly by chemical troops. It took a lot to provide troops with necessary chemical defence means. The fl amethrowers` mission was to burn the enemy out of long-term fi re facilities and fortifi ed
buildings, to block strongholds, and to destroy tanks and armoured personnel carriers. Smoke screens were used to mask rear objects, important industrial facilities in cities, railway junctions, bridges and crossings. Smoke screens masking signifi cantly reduced the effectiveness of German air force bombing.
Instructional Leadership Practices of Principals through the Lens of School Management Teams
Authors: Maponya Tebogo John
Published: October 2020

South African Education system has undergone numerous transformations, which gave rise to a new complexion in the instructional leadership practices in schools. As a developing country that is striving to match the global standard of education, incorporating new ideologies in leading and managing curriculum for the well-being of its learners has been a great leap that is commendable. The ideals of effective instructional leadership are among others that school principals in previously disadvantaged backgrounds are still grabbling with so far. This phenomenological empirical study sought to investigate the instructional leadership practices that school management team members perceived to be working well or not working well in their different schools. The manuscript captured some of the successes and hiccups and presents research findings from data collected from school stakeholders who expressed their desire to see growth and development that aims at improving schools for the better. Qualitative findings made showed that constructive interaction with teaching staff and other role players, creation of a positive working climate, equitable personnel work distribution, interchangeable leadership styles, and curriculum support worked well in schools. The study came up with the following in tackling what did not work well: communication, unnecessary disruptions by teacher unions, meagre and inequitable work distribution, as well as limited and poor parental support.
LineageOS Android Open Source Mobile Operating System: Strengths And Challenges
Authors: Ponakala Rajasekhar , Dailey Matthew N.
Published: October 2020

This study report is aimed at identifying opportunities and challenges in developing a completely free and opensource mobile operating system based on AOSP. In this report, I describe the installation of LineageOS on a OnePlus One mobiledevice. I first describe the installation of a pre-built LineageOS image to the device, andthen I explain how i compiled the available source to build my own LineageOS image forthe device. Source compilation provides a more complete understanding of device-level OSbuilds. I also discuss various alternatives to Google Mobile Services. All the available alternative services are in the development stage. A promising approach is the reverse engineering mi-croG project, which is a free and open source re-implementation of Google Mobile Services. Such alternatives to Google’s services, meaning client-side free and open source applications and libraries, provide an excellent base upon which can build completely free and opensource background services as well as applications on mobile devices.
Teaching Science in Rural Elementary Schools: Affordances and Constraints in the age of NGSS
Authors: Zinger Doron , Haymore Sandholtz Judith , Ringstaff Cathy
Published: October 2020

Providing science instruction is an ongoing priority and challenge in elementary grades, especially in high-need rural schools. Nonetheless, few studies have investigated the factors that facilitate or limit teachers’ science instruction in these settings, particularly since the introduction of the Next Generation Science Standards. In this study we investigated affordances and constraints to elementary science instruction in high-need rural schools. Data sources included semi-structured interviews and survey responses from 49 teachers from 30 different rural schools. Through a primarily qualitative analysis, we identified four teacher reported categories of affordances and four categories of constraints to teaching science. One category of affordances, access to a variety of outdoor science resources, and one category of constraints, high levels of isolation, were closely tied to the nature of rural schools. The other affordances and constraints are broadly recognized factors influencing science instruction. Implications for supporting rural teachers’ science instruction are discussed.
Od czego zależy jakość dialogu społecznego? Koncepcja modelu państwa administracyjnego i państwa sieciowego na przykładzie instytucji dialogu społecznego
Authors: Grosse Tomasz Grzegorz
Published: October 2020

What does the quality of social dialogue in the Central and European countries depend upon? There are three sets of factors which influence the quality of social dialogue, in other words, the social consultation regarding relations between employers and employees. The states in this legion share the common legacy of the years of socialism. They share the difficult experience of economic and political transformation. They have also recently joined the European Union. The other factors are the conditions of an economy which is undergoing globalisation and the challenges of competitiveness on the common market that are related to the European Integration. It is the last circumstances which seem to hinder social dialogue the most. They result in a situation where, to a large degree, it becomes a tool used to improve the competitiveness of the national economy and to liberalise the regulations pertaining to relations between employers and employees. Such assumptions concerning the operations of the institutions in question place the trade unions in a difficult situation. In a way which is obvious, this makes the building of solid institutions of social dialogue in the new EU member countries difficult.
Neutralność państwa
Authors: Oczkowska Żaneta
Published: October 2020

What does ‘the neutrality of the state’ mean and is it possible? There are two colliding concepts in political thought regarding the extent of the state’s intervention in the life of an individual. The first of them is minimalist and the second is that of the common good. It is in this context that it is worthwhile analysing what neutrality means. The dispute between the advocates of the state’s neutrality and its enemies is not only of a theoretical nature. The lack of agreement in this matter often leads to political conflicts, which antagonise not only politicians but also society in its entirety, as in the case of abortion or euthanasia. Neutrality is one of the main features of a contemporary, liberal state. In the liberal approach, the standpoint may be also put forth that compromise and toleration are the most important of liberal and democratic values. The essence of this is the separation of the sphere of the state from that of morality, which results in the creation of a space for discussion, polemics and dispute. Involvement on the part of the state raises controversy, most of all in the moral sphere related to one’s philosophy of life. When we talk of the neutrality of the state, the issue which comes to the fore is that of religious toleration and an issue akin to this, the issue of relations between the state and the church. The contemporary understanding of this matter is more narrow. Neutrality of the state is associated with the latter’s remaining distant from any philosophy of life, and not necessarily only that which is rooted in religion. The issue of religious toleration has, however, contributed to a large degree to the debates on the neutrality of the state which are being carried out at present and the very idea of the neutrality of the state is like a generalisation of the role of the concept of neutrality with regard to religion.
Democracy and the Church
Authors: Mazurkiewicz Piotr
Published: October 2020

The question arises whether the coherence between Democracy and the Christian vision of the person and Society as something much more essential or is it simply a matter of chance? It is only with Christianity, with its teachings on the concept of inviolable rights of the person, equality, political rights of the people, and the absolute value of relationships based on law and justice as the basis of society and based on fraternal love, created a new Vision of political order which all contemporary nations aim to implement. If not for the Christian concept of democracy, the democracy that we know today, would probably have taken a different form. The Church’s support for democracy is something unquestionable. However, not every kind of democracy automatically is in keeping with the teachings of the Church. This depends on a democracy’s relation to truth and freedom. The Church supports democracy today, however it does not support one, concrete vision of the political system of the State. It respects the just autonomy of the democratic order, and it does not have a concrete reason for supporting one particular institutional and constitutional solution or another.
Technokracja i demagogia
Authors: Gałkowski Stanisław
Published: October 2020

A modern society cannot function without experts in every field and without high level specialists. Before any undertaking is initiated, an issue of effectiveness emerges, one which only they may ensure. At the same time, however, it tends to be forgotten that there is no such thing as ‘just effectiveness’; there is only effectiveness in meeting the targets adopted. Technocracy, in itself, does not issue any social objectives. On the one hand, this is in  accordance with the liberal approach, which demands the neutrality of the state; on the other hand, however, it may lead, at the very least, to dangers to democracy, to the possible collaboration of technocrats with a totalitarian government, with this group possibly resorting to populism (that is, to an unthinking subordination to the demands of the masses) and, third, to an attempt to govern on their own by demagogy, making the voice of public opinion subject to its rule.
Kryzys filozofii polityki
Authors: Markowska Barbara
Published: October 2020

The purport of the article is a reflection on the operating conditions of the philosophy of politics, beginning with its crisis, as described by Leo Strauss in the early 20th century and continuing up to the latest proposals, which emerged at the turn of the 20th and 21st centuries. First, the author poses a question regarding the essence of this crisis; was it related to the scientific paradigm of the philosophy of politics applied hitherto or, rather, to the very subject matter of this scholarly pursuit, which is to say, to politics itself. A scientific discipline must be able to delineate its subject matter and if the latter undergoes an unexpected modification, the former suffers a crisis. Was this what happened to politics itself? What was the decisive factor which caused it to escape a theoretical consideration that ceased to be a systematic reflection, in short, ceased to be science, only to become philosophy again, whereby the author understands ‘philosophy’ as a level of reflection such as to allow itself to posit subliminal questions purely in order to set up the determinants for further thinking as to what science is, what politics is and what makes politics different from non-politics.
