Entre disputas partidistas y supervivencia. La guerra de los Mil Días (Colombia 1899-1902)
Authors: Escobar Guzmán Brenda
Published: December 2021

El artículo intenta mostrar que los conflictos ideológicos que enfrentaron a los notables colombianos en el siglo XIX pueden explicar la construcción discursiva del ambiente belicista que daba inicio a las guerras, pero se quedan cortos para comprender su desarrollo. Primero se ofrece una panorámica de la conflictividad del siglo XIX en Colombia resumiendo las discusiones que movieron en términos generales esos conflictos. Posteriormente el texto se centra en la última de las guerras internas del período, que por su prolongada duración se denominó “de los Mil Días”. Se quiere mostrar que si bien varios de los debates de orden trascendente que habían aparecido en conflictos anteriores también se observan en este, en el trascruso de la guerra se fueron debilitando estas grandes causas y jugaron un rol más importante las acciones por la mera supervivencia, generadas al calor del enfrentamiento armado.

Female everyday life in letters by a Karelian peasant woman of the early XX century
Authors:   Institute of Linguistics, Literature and History, Ilyukha Olga P.
Published: December 2021

Introduction. The article reports the results of an analysis of the letters written by a peasant early in the XX century, found in the National Archives of Finland, which are a rare-type of historical source. Their author is a twenty-year-old peasant Anna Eremeeva-Räikha, who wrote them to her husband exiled to North Kazakhstan. The relevance of the study is defined by high interest to epistolary cultural heritage, where a special place is given to the letters of Russian’s different ethnic groups, and also by attention paid to the history of everyday life. Materials and Methods. The principal method was analysis of the structure of the letters, including identification of thematic block sequences and their subsequent clustering for the analysis of specific issues. Results and Discussion. The article explicates the substantive dimension of the letters, which reflects the sphere of interests of their author, and looks into the descriptions of women’s daily routines and the life of the Karelian family. It highlights the range of covered subjects and outlines the topics showing the routines and the behavioral practices of a peasant woman, her ways of adapting to the new circumstances after the husband’s arrest. The specific jobs and occupations are aligned with the farming calendar of northern Karelia. Features of the author’s self-presentation, ways of structuring and drawing up the texts are demonstrated. The study illustrates the range of topics and emotions rooted in the gender factor, and the diversity of their expression. Conclusion. The letters disclose the system of moral values of a Karelian woman, the Christian ideal of family relationships, special features of professional motivations. The “voice” of a Karelian peasant woman retained in these letters is a relevant source for studying the alteration of women’s everyday life early in the XX century and it allows talking about the maturing demand for emancipation in everyday life and gradual loosening of the traditional gender order in the Karelian village.

Authors:   Ural Branch of the Russian Academy of Sciences, Gorinova Natalia V.
Published: December 2021

Introduction. The work is devoted to the study of the theatrical and dramatic work of O. Ulyashev. It reveals the originality of his dramatic handwriting and some aspects of the movement of national culture in the 1990s. Materials and Methods. The material of the study was the plays by O. Ulyashev. The method of study is comparative. Results and Discussion. O. Ulyashev’s plays are an important milestone in the history of the development of the Komi Theater. His plays, like many other ones of the turn of the XX–XXI centuries, are inherent in the desire for renewal. The artistic originality of his texts, however, determines the actualization of folklore material. The writer’s worldview is close to the high artistic, aesthetic and moral and philosophical potential of oral folk art. It is folklore origins that contribute to his creative quest and the development of his creative aspirations. O. Ulyashev’s works, like many other works of Komi literature of the late XX century about the historical past of the Zyryans, serve to increase and strengthen national identity. Conclusion. The work of the writer O. Ulyashev played an important role in the development of theatrical and dramatic art of the Komi Republic. His plays largely update the Komi drama, saturating it with folklore material, romanticizing the past of the Zyryans.

Published: December 2021

A sensitive and accurate LC-MS/MS method was developed and validated for the simultaneous quantification of rivaroxaban (RIV) and sitagliptin (SIT) in rat plasma using apixaban as internal standard (IS). An Agilent Eclipse plus C18 column (2.1 × 100 mm, 3.5 µm, Agilent) was used for chromatographic separation with isocratic elution. Multiple reaction monitoring (MRM) using positive-ion ESI mode to monitor ion transitions of m/z 436.8→144.9 for RIV, m/z 407.7→173.8 for SIT, m/z 459.8→442.8 for IS. The procedure of method validation included selectivity, linearity, precision, accuracy, matrix effect, extraction recovery and stability were conducted according to the guidelines of EMA and FDA. The results indicated that no obvious drug-drug interactions occurred might be owing to their differences in metabolic pathways.
Physical and physiological benefits of small sided recreational handball in untrained males: relationship of body fat with aerobic capacity
Authors: Tomar Rakesh , Allen John A.
Published: December 2021

Background and Study Aim. Exercise and Recreation play major role in promotion of health and fitness. Recreational exercise or sports can be useful in physically inactive population. The aim of study was to investigate the effect of recreational handball on body fat percent, VO2max, blood pressure and resting heart rate. Another purpose to find relationship between VO2max and body fat percentage.
Material and Methods. Twenty-four students were randomized into intervention (n=14) and control group (n=10). The intervention group was asked to play recreational handball for 12 weeks. Handball training was held twice a week for 30 minutes duration. The Control group performed their normal routine. Aerobic capacity measured using single-stage treadmill test. Body fat was measured with Omron Body Fat Analyzer. T-test was employed to find a significant difference in the two groups. For the relationship in aerobic capacity and body fat, Pearson Product Moment Correlation was used.
Results. We found significant difference in body percent (t22 = 2.031, P = 0.054). No significant difference was seen in aerobic capacity (t22 = 1.578, P = 0.129), systolic blood pressure (t22 = -1.637, P = 0.116), diastolic blood pressure (t22 = -1.562, P = 0.133) and resting heart rate (t22 = 1.620, P = 0.120). Significant relationship was established between body percent and aerobic capacity (r= -5.23, n=14, p= 0.055) in the intervention group.
Conclusions. It can be concluded that recreational handball was useful in eliciting good response with respect to reduction of body fat in intervention group. However, recreation handball sessions were not effective in reducing blood pressure, resting heart and aerobic capacity among untrained males. A significant relationship was observed in VO2max and percent body fat.

Authors: Bayraktar Yasemin , Erkmen Nurtekin , Kocaoglu Yagmur , Ünüvar Bayram Sönmez
Published: December 2021

Background and Study Aim. Although Kinesiotape is widely used by athletes, information about its effect is unclear. Its effect on postural control might directly affect an athlete's performance. In this study, it is aimed to find out whether ankle Kinesiotaping in taekwondo athletes affects postural control.

Material and Methods. Twenty-four healthy university students – taekwondo athletes (12 females, 12 males) were included in the study voluntarily (Age 21.00 ± 1.53 years; height 173.33 ± 7.29 cm; body weight 63.41 ± 9.41 kg). Kinesiotape was carried out to the dominant ankle of the participants. Kinesiotape was applied supportively to peroneus longus, peroneus brevis, and tibiofibular ligament. All participants were taken to postural control measurements twice with Kinesiotape (KT) and without KT. Postural control was measured using the Biodex Balance System with eyes open (EO) and eyes closed (EC). Overall Stability Index (OSI), anterior-posterior sway (AP) and medio-lateral sway (ML) scores were used in the evaluation of postural control. Wilcoxon test was used to compare balance scores under EO condition, and the t-test was used for dependent groups to compare balance scores under EC condition.

Results. In EO condition, no significant difference was found between OSI, AP, and ML scores of the taekwondo athletes with KT and without KT (p > 0.05). In EC condition, no significant difference was found between OSI, AP, and ML scores of male taekwondo athletes with KT and without KT (p > 0.05). It was found that Kinesiotape in EC condition decreased OSI and AP sway scores in female taekwondo athletes (p < 0.05).

Conclusions. It was determined that ankle Kinesiotaping of taekwondo athletes did not change the postural balance in EO condition. In EC condition it did not change the postural sway of male taekwondo athletes, but it improved the postural control performances of female taekwondo athletes.

Authors: Chernenko Serhii , Jagiello Wladyslaw , Ivashchenko Olha , Khudolii Oleg , Pashkevich Sviatoslava
Published: December 2021

Background and Study Aim. The objective of the study was to determine the peculiarities of impact of sports specialization on 3rd-year female students’ functional and motor fitness.
Materials and methods. The study involved 3rd-year female students of the Donbas State Engineering Academy in Kramatorsk, who practiced badminton (n = 43), aerobics (n = 43), and callanetics (n = 43). To solve the tasks set, the following research methods were used: analysis of scientific literature, pedagogical observation, pedagogical testing; index method and medical-biological methods. Pedagogical methods were used to study the peculiarities of students’ functional state of the body and motor abilities; for data processing discriminant analysis was used. Sectional classes were held in groups according to the schedule – twice a week.
Results. The study revealed the peculiarities of impact of attending badminton, aerobics, and callanetics sports sections on the level of 3rd-year female students’ functional and motor fitness. The female students who play badminton show better results in the 100-meter dash and the Standing long jump. In the exercise “Push-ups”, better results are shown by the female students who do aerobics.
Conclusions. The results of classification of students by the level of motor and functional fitness and the analysis of multidimensional averages (centroids) point to the peculiarities of dynamics of female students’ state depending on sports specialization. The results of the following tests are most important for differentiated assessment of the state of motor and functional fitness at the first level: Romberg test (r = 0.662), 100-meter dash (r = 0.491), Push-ups (r = 0.491). At the second level – Stange test (r = 0.417), Standing long jump (r = 0.412).

Artist’s Psychophysiology in Disposition to Style (Case Study of Lesia Ukrainka’s Biography Materials)
Authors: Yastrubetska H. I. , Levchuk T. P.
Published: December 2021

Purpose of the study is to shed light on the role of psychophysiology in the creative process, namely, the style corrections connected with pathological changes in the artist’s organism, deviating from empirical-descriptive methods. Theoretical basis of the study implies the interpretation of the notions style and disease not in their narrow professional limitation but from the standpoint of expanding the parameters of these concepts to philosophical dimensions. Based on the principle of analogy, the research findings prove that non-mimetic creative process ("pure" action) manifests itself exclusively in connection with a human from a bodily viewpoint through anthropological mimesis, which can program the propensity to certain capabilities of the individual organism (both psycho-physiological and in its creative and stylistic manifestations). C. G. Jung was the first who pointed to the productivity of this method in his work "Theoretical Reflections on the Nature of the Psyche". The creativity phenomenon (and its most specific feature – style) reflects not only "pure" psychology and the intellectual and spiritual component but also its relation to the artist as a physical being. It, outside its belonging to and being conditioned by transcendent factors, includes a quantitative aspect related to the moment of intensity. The disease (quantitative-intensive indicator) acts to some extent as a stimulator of the production/change of aesthetic enzyme ("The Obsessed" by Lesia Ukrainka). In this context, the dialectic method is also effective because the subject of study cannot be comprehensively argued using naturalistic approaches only and requires (according to A. Losev) a semantic explanation too. The essence of it is the logic of contradictions. In this case, the antinomy of matter-spirit plays a conceptual role in the projection on the plane of word-formation. Originality of the research findings is in the expansion of the causal relationship range of the creative process, namely the inclusion of the factor of psycho-physiological pathology into the system artist-work. This factor performs important stylistic functions. Conclusions. In contrast to scientific studies, where 1) style is analyzed separately (mostly in terms of text landscape description) and 2) the figure of the artist (mainly – in the parameters of empiricism, rarely – in psychoanalytic perspective), this study argues the need to correlate these issues, taking them beyond descriptiveness to avoid schematics and one-dimensionality.
Human Being in the Dimension of the Psychosociocultural Matrix of Philosophizing
Authors: Karpenko I. V. , Guzhva A. A.
Published: December 2021

Purpose. The article highlights the demand for critical thinking in everyday life at the present stage of development of globalized culture and emphasizes the role of philosophy as a source of rationality. Philosophizing, which is determined by the psychosociocultural matrix, sets the toposes, vocabulary and rhythms of meaning making, their preservation and transformation. The purpose of the article is to concretize the practices of socio-cultural communication, primarily through the social institute of education, where individuals interact with the psychosociocultural matrix of philosophizing, which mediate the general and individual level in philosophical culture. Theoretical basis of the study are cultural anthropology and phenomenological methods. Originality of the study: based on the philosophy of intersubjectivity, we actualized the rational grounds for formation of adequate judgments in modern culture at the level of everyday life. This justifies the inevitability of the spread of various forms and types of philosophical education, philosophical thinking, ideas and values developed in philosophical communities beyond the narrow circle of professional philosophers. This implies the systemic involvement of philosophers as professionals of meaning-making in solving problems in various non-academic fields – politics, economics, law, etc. The formation of skills of philosophical critical thinking in the process of preparing young people for active civil life is no less important aspect of this. Conclusions lead to an understanding of the existential importance of philosophy and philosophizing and the need for organized forms of knowledge transfer such as the Faculty of Philosophy of the Classical University. There is a mutual interest and interaction of the general culture of society and philosophy as a special kind of culture. Because philosophy actively configures other forms of culture, contributes to the creation of sociocultural identities precisely because of its ability to conceptually reproduce the core of the psychosociocultural matrix that underlies the existence of all these different forms within one society. The sociocultural macro level of philosophical spiritual practices is formed by the psychosociocultural matrix of the philosophical tradition, which retains its longevity from the emergence of philosophy and goes through its history, demonstrating the features of the national reception of philosophy as a national-specific embodiment of sociocultural macro level of the psychosociocultural matrix.
Analytical Anthropology of Peter Hacker
Authors: Popov V. Y. , Popova E. V.
Published: December 2021

Purpose. The article is an explication of the features of the anthropological teaching of Peter Hacker in the context of analytical philosophy with consideration to the context of European philosophy within the framework of the Oxford School of ordinary language philosophy. The theoretical basis of the research is determined by the latest research in the English-language analytical philosophical tradition, rethinking the place of anthropological problems in the system of philosophical knowledge. Originality. Referring to primary sources, we reconstructed the philosophical and anthropological teaching of Peter Hacker in the unity of its basic principles and theoretical and practical results. We determined philosophical origins of the key ideas of his philosophical anthropology and substantiated their originality, systematicity and logical argumentation. His philosophical position is defined as anthropological holism, synthesizing the reinterpreted ideas of Aristotle and Wittgenstein. Conclusions. Peter Hacker is the creator of the original version of Analytic Philosophical Anthropology. His anthropology is based on criticism of Cartesian dualism and physicalism, which underlie modern neurosciences and which he tries to overcome on the basis of Wittgenstein’s philosophical "logotherapy". The conceptual framework of his holistic anthropology is a rethought conceptual scheme of the Ordinary language philosophy. Hacker considers consciousness not as a separate mental reality, but one of the powers of human nature – an intellectual ability, which, along with emotional (passionate) and moral, belongs to a person as an integral socio-biological being. Asserting the free will of man, the Oxford thinker criticizes various forms of determinism, especially its most common form in modern science – neurobiological determinism, which is built on false philosophical foundations. This criticism allows the modern British philosopher to build an original, systematic and logically consistent anthropological concept that asserts the immutability of the highest human values – goodness, love and happiness.

Published: December 2021

Purpose. The aim of the work is to develop a method for estimating the capacity of garages for defrosting the transport system of an industrial enterprise. Research methods. In the course of the research methods of analysis and logic were used to evaluate scientific and technical publications related to the development and calculation of the capacity of technical devices of cargo stations and unloading complexes. Results. The method of estimating the capacity of defrosting garages of the transport system of an industrial enterprise is developed in the work. The developed method is based on the comparison of the calculated and required capacity of garages for defrosting of large unloading complexes of industrial enterprises. The need to introduce the reserve capacity of defrosting garages in connection with the influence of dynamic factors into the model is substantiated during the research. The scientific novelty lies in the development of a method for estimating the capacity of garages for defrosting the transport system of an industrial enterprise. Practical value. The developed method of capacity assessment allows to optimally, comprehensively synchronize the operation of defrost garages and unloading complex with processing capacity and thus increase the efficiency of management of the transport system of an industrial enterprise.
IMPROVEMENT OF THE LOGISTIC SERVICE OF RAILWAY FERRY
Authors: DEMCHENKO Ye.
Published: December 2021

Purpose. In modern conditions, Ukraine, having an extensive railway network and a developed infrastructure of seaports located on its Black Sea coast, is becoming a link in new goods delivery routes in the direction of the EU-China. Transportation of large consignments of goods in the direction is usually carried out in containers by sea transport. At the same time, such transportation is characterized, on the one hand, by a relatively low cost, and on the other hand, by rather long delivery times. An alternative case is transportation by mixed rail-water communication, which allows, with a moderate increase in cost, to achieve a significant reduction in the delivery time of goods. The economic attractiveness of such a transportation scheme depends significantly on the performance of ferry crossings in the Caspian and Black Seas. In this regard, the purpose of this work is to increase the efficiency of international ferry services by improving its logistics support on coastal ferry complexes. Methodology. To achieve the work purpose, methods of statistical analysis were used to determine the volume and structure of ferry traffic; simulation methods to determine effective options for loading ferries; theory of shunting work to optimize the car classification according to the cargo plan. Results. There were analyzed the requirements for ferry loading and developed a computer model that allows to create acceptable plans for the cars location on ferry decks (cargo plan). On the basis of the obtained variants of the cargo plan, the modeling of the multi-group trains forming by combinatorial and distribution methods has been carried out. Based on the simulation results, recommendations of choosing the effective method for train forming and the required number of cargo plan variants were given. Scientific novelty. The author has improved the method for determining the effective cargo plan of the ferry loading, which takes into account the process of forming the trains of cars to be supplied to the ferry. Practical significance. The obtained results can be used to improve the efficiency of international freight transportation management in mixed rail-water traffic.

Synthesis, structure, and visible-light-driven activity of o-YbFeO3/h-YbFeO3/CeO2 photocatalysts
Authors: Tikhanova Sofia M. , Lebedev Lev A. , Kirillova Svetlana A. , Tomkovich Maria V. , Popkov Vadim I.
Published: December 2021

Photo-Fenton-like oxidation of organic substances is one of the key advanced oxidation processes based on the reversible Fe2+↔Fe3+ transition and the generation of a strong oxidant ·OH in the presence of H2O2 and is currently considered as a promising method for the purification of polluted aqueous media. However, the absence of effective and stable photocatalysts of this process, operating under the action of visible light, necessitates the exploratory studies, mainly among iron oxides and ferrites of various compositions and structures. In this work, using the method of solution combustion followed by heat treatment in air the heterojunction nanocomposites based on ytterbium orthoferrite and cerium dioxide of the composition o-YbFeO3/h-YbFeO3/CeO2 (0–20 mol.%) with high absorption in the visible region and advanced photo-Fenton-like activity were obtained. The nanocomposites were studied by EDS, SEM, XRD, BET, and DRS methods. The photo-Fenton-like activity of the nanocomposites was investigated during the degradation of methyl violet under the action of visible (λmax = 410 nm) radiation. As a result, the formation of I-type heterojunction based on stable rhombic (55.4–79.0 nm) and metastable hexagonal (19.5–24.0 nm) modifications of ytterbium orthoferrite (o-YbFeO3 and h-YbFeO3, respectively) and cubic cerium dioxide CeO2 (13.2–19.2 nm) nanocrystals was established. It was shown that the obtained nanocomposites had foamy morphology and were characterized by a specific surface in the range of 9.1–25.0 m2/g, depending on the CeO2 content. It was found that nanocrystalline components were chemically and phase-pure, uniformly spatially distributed over the nanocomposite, and had multiple contacts with each other. Based on this fact and the established electronic structure of the nanocomposite components, the formation of I-type heterojunction with the participation of o-YbFeO3 (Eg = 2.15 eV), h-YbFeO3 (Eg = 2.08 eV), and CeO2 (Eg = 2.38 eV) was shown, the presence of which increased photocatalytic activity of the resulting nanocomposite. The optimal content of CeO2 in the nanocomposite was 5%, and the o-YbFeO3/h-YbFeO3/CeO2–5% sample was characterized by the highest rate constant of photo-Fenton-like degradation of methyl violet under the action of visible light equal to k = 0.138 min–1, which was 2.5 to 5 times higher than for nanocomposites based on ytterbium orthoferrite. The obtained results obtained indicate that the developed nanocomposites can be considered as a promising basis for the advanced oxidation processes for the purification of aqueous media from organic pollutants.

Efficiency of ultrasonic treatment of polysaccharide from brown algae
Authors: Suprunchuk Victoria E.
Published: December 2021

Ultrasonic exposure can be used for depolymerization of brown algae polysaccharides. However, its effectiveness depends on several factors, including cavitation activity in the treatment medium. Therefore, the purpose of the work was to determine the cavitation activity and the effectiveness of the ultrasonic exposure to fucoidan in order to optimize the processing processes of polysaccharide from brown algae. A change in cavitation activity was revealed depending on the composition of the processing environment, as well as on the intensity of ultrasonic exposure with a constant frequency of the ultrasonic wave. Similar dynamics of change of cavitation activity were established at the intensity of ultrasonic treatment of 100 and 133 W/cm2 with amplification of electric signal at the increase of ultrasound intensity. The use of SDS in the processing medium led to an increase in cavitation activity to 14.9±0.47 mV. Treatment of the fucoidan solution for 40 minutes under various conditions allowed to obtain fractions with a change in the average hydrodynamic particle diameter from 113 nm (100 W/cm2) to 85 nm (200 W/cm2) and 124 nm (SDS).

Published: December 2021

The work is devoted to the study of nanocomposites based on synthetic (styrene-butadiene) rubber with different fillers not previously used. The issue of using composites with alternative fillers is being investigated. The results of experimental testing and analysis of thermo-visco-elastic behav-ior of styrene-butadiene rubbers filled by various mineral particles of micro and nanosize, as well as pyrolysis products of organic food waste, are presented. The filled elastomers discussed in this work are mainly used in the tire industry to improve the performance of tires. All samples were tested on a dynamo-mechanical analyzer (DMA). Temperature and frequency dependences of the dynamic modulus and loss modulus are plotted for each of the composites. The frequency charac-teristics corresponded to the real range of rotation speeds of the car wheel, and the temperature var-ied from –50 to +50ºC. A comparative analysis of the results obtained was carried out. The struc-tural mechanisms of the filler are not investigated. It is assumed that the principles of operation of the investigated fillers at the structural level are similar to those described in many works for clas-sical fillers. Based on the test results a conclusion about the preferable operating conditions for the considered materials was made.

Authors:   Tomsk Polytechnic University, Khoa Le Xuan Hoang , Sheremet Mikhail A. ,   Tomsk Polytechnic University,   Tomsk State University
Published: December 2021

The development of energy instrumentation, electronic industry and energy in general is inextrica-bly linked with the intensification of heat and mass transfer occurring in the base units and aggre-gates of energy systems. One of the approaches to solving this problem is to create an extended heat transfer surface by introducing a rib structure or porous inserts. This work is devoted to math-ematical modeling of natural convection in an enclosure in the presence of a rib structure and non-uniform temperature profile on one of the vertical walls. The governing partial differential equa-tions written using dimensionless non-primitive variables “stream function – vorticity – tempera-ture” based on the Boussinesq approximation, in combination with initial and boundary conditions, have been worked out on the basis of the finite difference method. The developed computational model was varified using the mesh independence test and benchmark problems solved by other au-thors. Numerical investigations of unsteady natural convection of viscous fluid in a cavity with a variable temperature on the left wall under an influence of a rib structure have been carried out for the following values of governing parameters: Pr = 0.71, 103 < Ra < 106, and the number of ribs varied from one to three. Distributions of streamlines and isotherms, as well as the dependences of the average Nusselt number and average cavity temperature, were obtained for a steady mode. As a result of the analysis, it has been found that the addition of solid ribs allows to enhance the heat transfer for low Rayleigh numbers, while for Ra  105 one can find an attenuation of convective heat transfer. A growth of the fins heat conductivity characterizes the heat transfer enhancement.

New data on the phylogenetic diversity of bacteria in the salt of the Verkhnekamskoe deposit (Perm Krai) have been obtained using molecular genetic methods. Analysis of the 16S rRNA genes of total DNA from the rock salt sample (depth intervals of 239.7-239 m) evinces the presence of bacteria belonging to the classes: Actinobacteria (closely related to the genera Rhodococcus, Demequina), Gammaproteobacteria (the genera Pseudomonas, Serratia, Shigella), Betaproteobacteria (the genus Ralstonia) and Alphaproteobacteria (the genus Phyllobacterium). In addition, we identified two phylotypes of the Alphaproteobacteria (clone 66BA (GenBank MH410136) and clone 12BA (GenBank MH410128) that show lower similarity in 16S rRNA genes (98.46%) with the closest type strains of the genus Mesorhizobium (M. alhagi CCNWXJ12-2T) and the genus Chelativorans (C. multitrophicus DSM9103T). The identified phylotypes may represent new taxonomic units.

To move in the environment, bacteria use several types of translocation. Sliding is a passive meth-od of movement, which is carried out due to the expansive force, which increases during cell division. This re-view describes the sliding mechanism, different types of sliding mobility, from other types of bacteria. In addi-tion, a classification of sliding types is used, surface active substances used by cells to slide. However, it is worth noting that bacterial slide mechanisms need further investigation.

There are 70 species and forms in the composition of zoobenthos of the river Ural and in water bodies of its floodplain have been identified. Mayflies and chironomids are represented in various ways (13 and 12 species and forms, respectively). Caddisflies (10) and stone flies (7) are rich in species. Among other invertebrates, bivalves (6) and gastropods (5), small-bristled worms (5), non-chironomid dipterans (4), leeches, crustaceans and dragonflies, bugs and beetles were recorded. On sandy-gravel-pebble soils is formed a zoobenthocenosis, dominated by the mayflies Ephoron virgo. They are accompanied by Chironomidae larvae. The biomass of the community varies between of 29.32–31.68 g/m2 with an abundance of 18.1–32.44 thousand ind./m2. In the coastal of the channel is formed a pelophilic zoobenthocenosis, the basis of it abundance and biomass are constituted by the small-bristle worms Limnodrilus hoffmeisteri. They are accompanied by mollusks Stagnicola palustris and mysids P. lacustris. The biomass of the pelophilic community is 13.68 g/m2 with a population of 15.45 thousand ind./m2. In floodplain water bodies are formed pelophilic zoobenthocenoses, the biomass of which varies in the range of 19.2–34.24 g/m2 with an abundance of 5.64–30.04 thousand ind./m2. Chironomid larvae constitute the base of the population. The biomass is composed by dragonflies Libellula sp., Chironomids, and mollusks Bithynia tentaculata.

The object of the study was sires of the Black-and-White and Holstein breeds, which had STR profiles and passed the genotyping procedure for SNP markers. The subject of the study was the level of genomic inbreeding and homozygosity, as well as population-genetic characteristics based on them. With an increase in Fx based on pedigree data, an increase in the level of genomic inbreeding (FROH) calculated from SNP markers was also noted. The results for 9 STR markers record a wavelike increase in homozygosity from group I to group IV with a subsequent increase from group V to group VII inclusive. During the study of the average FROH values in accordance with the years of birth of sires, a significant difference was found between the last two groups (2009-2011; 2012-2014) from all the others in a pairwise comparison. The results of calculating the FROHand Ca9 of bulls from different countries of origin indicate a statistically significant differentiation of the group of animals from Russia (RF) from animals, born in German and Canadian. A significant difference was noted for the highest FROH level in the samples in the Holstein Black-and-White breed from the Red-and-White Holstein and Black-and-White breeds. The Fst values between the SNP and STR species of the animals had insignificant differentiation (0.008-0.027). Differences in STR calculation between the Black-and-White Holstein and Red-and-White Holstein breeds were insignificant, less than 20%, while the rest of the values differed many times. Fst between RF and Germany, RF and the Netherlands according to STR data is 0.006 and 0.008, according to SNP data 0.005 and 0.006, respectively. A mutual increase in the value of Fst and the year of birth of the sires was noted, emphasizing the greatest remoteness of the population of 1983-1997 from the populations of recent years, when new genotypes of bulls were obtained. The similarity of Fst values between genealogical lines is replaced by a significant scatter in the indicators when they are compared in pairs.

The standard method to study T-cell proliferation is flow cytometric evaluation of the intracellular Ki67 expression. However, this analysis requires preliminary cell fixation and permeabilization that limits further research. The aim of the present work was to evaluate the possibility of using the surface molecule CD71 as an alternative marker for T-cell proliferation. Frequencies of CD71+ and Ki67+ T-lymphocytes and candidate proliferation markers’ expression levels were studied in unstimulated and phytohemagglutinin-stimulated human peripheral blood cells using flow cytometry. We found that stimulation increases the frequency and level of Ki67 and CD71 expression in CD4+ and CD8+ T-cells. We revealed a strong positive correlation between the two molecules in different T-cell subsets. It should be noted that all Ki67+ T-cells expressed CD71, while the majority of CD71+ cells did not express Ki67. Based on the data obtained, one can conclude that CD71 is not a complete analog of Ki67, but it can be used for investigations of activated/cycling T-lymphocytes.

Post-harvest activities of agricultural products often generate wastes. One of the agricultural wastes that increase every year is corn cobs, which have a high cellulose content and can potentially be used as raw materials for making natural fibers. Therefore, this study aims to examine several potential commercial products from corn cobs. The method used is a literature study by tracing the sources of previous writings. Furthermore, how to process corn cobs waste for the manufacture of natural fibers and commercial products will be discussed. From the previously traced sources in the utilization of corn cobs waste, 4 products were obtained. The results are nano hydrogels based on gamma radiation, activated carbon with a carbonation process, bioethanol using the SSF process, and the use of corn cob cellulose as good-quality brake lining.

Authors: Demina Irina
Published: December 2021

This study extended the author's previous research in the field of scientometrics of media researchers on the topic “Mass information. Journalism. Mass media” in Russian electronic library and Russian Science Citation Index. The methodology was a census of the personalities of the first hundred authors ranked by the level of the h-index in 2020 compared to 2017, and in some aspects — from 2016. The study analyzed the changes in the h-index over the years under study, changes in the authors' geography by federal districts and cities of the Russian Federation, their academic position, the distribution of doctors and candidates of sciences in scientific majors in accordance with the awarded degree, as well as the distribution of rating personalities by actual scientific interests and taught courses in their affiliated scientific and educational organizations. The study revealed the importance of scientometric indicators for authors and scientific and educational organizations to determine their place in the academic community, the relevance of topics and authors’ research in the general academic landscape, and material incentives. At the same time, it was noted that the system of scientometric indicators is changing: perhaps the h-index the number of published works and the number of citations in the RSCI will remain as an object of research by historians of science to determine the common place of Russian (and Soviet) scientists in the science development, and in addition or to replace them there will be new indicators. One of them is the "percentile" recently introduced into the list of scientometric indicators. Studies of the values of scientometric indicators will remain relevant in the future.
