“ON THY BRIGHT BROWS I READ THY DOOM…”. THE TOPOS “THE PROPHET ON THE TROOPS’ WAY” IN THE GERMANIC AND CELTIC TRADITIONS - A HISTORY AND/OR A MYTH
Authors:   Institute of Linguistics RAS, Mikhailova Tatyana A.
Published: August 2022

The paper analyses the structural changes introduced by A.S. Pushkin into the original text: the description of prophesying “death by the horse” to Prince Oleg in Russian Primary Chronicle. The author points out that, in contrast to the chronicle, the ballad’s text depicts not the Prince’s own prophet but an ethnically alien Slavic wolkhv. Thus the prophecy through the mouth of a foreign magus can be regarded as a kind of a curse. Apart from this, in contrast to the depiction of the episode in Russian Primary Chronicle, Pushkin describes encountering the wolkhv who appears on the marching troops’ way. The paper provides parallels to this model found by its author and also describes similar episodes from both the history of Rome and epic texts (“Nibelungenlied”, Irish sagas). As Pushkin’s ballad’s major differences from the given episodes which do not contradict the clusters of motifs of the narrative scheme, the paper points out the following: 1. In all the given examples the encounter takes place at a ford. 2. In all the given examples the prophet is of feminine gender. The author attempts to find sources for Pushkin’s text outside the actual Russian history. The question of possibility of unconscious realising of motif schemes is posed as a preliminary conclusion

Published: August 2022

İmalat sanayinde büyük öneme sahip olan talaşlı imalat prosesinde istenilen, hassas tolerans aralığında ve düşük yüzey pürüzlülük değerlerinde parça imal edebilmek en önemli amaç olarak görülmektedir. Yüzey kalitesi ve ölçü tamlığı, temas ve etkileşim halinde çalışan makine parçalarının dayanımını ve performansını önemli derecede etkilemektedir. Bu çalışmalar esnasında CNC tornalama işlemi ile üretilen ve özellikle imalat sektöründe genişçe kullanım alanına sahip olan SAE 1040 malzemelerin geometrik tolerans değerlerinden silindiriklik, dairesellik ve doğrusallık değerleri analiz edilmiştir. Prosese etkisi yüksek olan bu bağımlı değişkenler üzerine etki eden, tornalama işlemlerinde büyük öneme sahip olan kesme parametre değişkenlerinin etkisi incelenmiştir. Deneyler DOOSAN Lynx 2100 CNC torna tezgâhında Q8 Brunel XF 450 soğutma sıvısı kullanılarak gerçekleştirilmiştir. Takım tutucu olarak WIDIA DWLNR-2525M08 ve kesici uç olarak WNMG0804086P TN20P tercih edilmiştir. İşlemler üç farklı talaş derinliğinde (1 mm, 1.5 mm, 2 mm), üç farklı kesme hızında (150 m/dak, 200 m/dak, 275 m/dak) ve üç farklı ilerlemede (0.15 mm/dev, 0.2 mm/dev, 0.24 mm/dev) gerçekleştirilmiştir. Deneyler sonrası elde edilen numune parçalarının silindiriklik, dairesellik ve düzlemsellik değerleri DEA GLOBAL CMM 3D ölçüm cihazında ölçülmüştür. Elde edilen verilerin değerlendirilmesi için, istatistiksel yöntem olan Taguchi metodu kullanılmıştır. Bu metot ile deneylere harcanacak zaman ve maliyetten tasarruf sağlanmış, deney sonuçlarından elde edilen veriler yorumlanmıştır. Ek olarak bağımlı ve bağımsız değişkenler arasındaki en etkili olan parametreleri belirlemek için varyans analizi (ANOVA) kullanılmıştır.
Мolecular-genetic analysis of determinants encoding β-galactosidases of bacteria Bifidobacterium longum BIM B-813 D
Authors: Morozova A. N. , Akhremchuk A. E. , Golovnyova N. А.
Published: August 2022

The molecular-genetic analysis of the bacterial genome of the strain B. longum BIM B-813D distinguished by a high level of β-galactosidase production was performed. Genes Bgal_small_N, lacZ1, bgaB1, bgaB2 and bgaB3, and lacZ2, encoding the synthesis of β-galactosidases, were revealed in the deciphered genome. It was shown that the genes lacZ1, bgaB2, and bgaB3 characterized by an enhanced degree of similarity to the genes of closely related bifidobacterial species, presumably code for the enzymes catalyzing the specific reactions of hydrolysis and transglycosylation of carbohydrates. It was found that the enzymes BgaB1, BgaB2 and BgaB3 belong to the GH42 family of glycosyl hydrolases, whereas the enzymes LacZ1 and LacZ2 – to the GH2 family. The genome domains responsible for the synthesis of β-galactosidases in the strain B. longum BIM B-813D were studied in detail. A comparative analysis of the locus of lacZ1 in B. longum BIM B-813D and the similar genome fragment AS143_01230 from B. longum subsp. longum MC-42 detected the presence of the transposase gene ISL3 in the former strain. It was suggested that the insertion of the sequence of ISL3 in the lacZ1 locus resulted in the modified gene expression and the increased production of β-galactosidase in the strain B. longum BIM B-813D.

Тhe mechanisms of differentiation of mesenchimal stem cells into the somatic cells of organs and tissues underlying embryogenesis and natural reparation processes and providing the structural and functional homeostasis of cells are considered. The data on adipogenic, osteogenic, chondrogenic, miogenic, and endothelial differentiations are given, which results in the formation of the cells of mesodermal origin in organism. The problem is discussed, how the transcription factors control each type of differentiation and participatе in them using various regulatory biomolecules, transcription factors, cytokines, and chimokins being in complicate permanent interactions and forming the integrity regulatory network. The participation in differentiation processes of a number of transcription factors (Runx2, Sox9, PPARγ, MyoD, GATA4 и GATA6) is discussed, the expression of which is under a permanent chemical control within the cellular regulatory network.
Livestock products in Belarus: per capita production
Authors: Tsarenok A. A. , Karpenko A. F.
Published: August 2022

The article is addressing the dynamics of livestock numbers in public and private agricultural farms and enterprises of Belarus over the years from 1941 to 2021. It is remarked that over a 50-year period the number of pigs increased twice, that of beef cattle increased more than twice, dairy cows – by 1,2 times, goats – by 1,07 times. Over the same period, sheep and horse numbers declined 6,3- and 5,4-fold respectively. Starting from 1991 and up until 2021, the numbers of dairy cows, pigs, sheep and horses declined signiﬁcantly (37, 43, 78 and 84,3 % respectively).

In 2020, as against 1990, the live weight of cattle and poultry made 100,1 % and 108,8 % in carcass weight; milk production made 104,1 %. Per capita production of meat, milk and eggs was respectively 21 kg, 99 kg and 15 pieces more than in previous years. Increased per capita production of the basic animal products not only guarantees food safety in the country, but it also provides with export possibilities inviting the inﬂow of foreign currencies.
Cultivation of corn for grain: the state of the industry, labor productivity, work eﬃciency
Authors: Shundalov B. M.
Published: August 2022

Large-scale cultivation of corn for grain is an urgent task of the functioning of Belarusian agricultural organizations. For this purpose, technological methods of growing this crop have been worked out and tested in production conditions. The biological features of local maize varieties are determined taking into account natural and climatic conditions.

In Belarus, the sown area of corn harvested for grain increased by more than 1,7 times in 2016– 2018, the gross grain harvest increased by 45 %. The average yield of 1 ha of crop during this period ﬂuctuated in signiﬁcant aisles – from 5 to 6,5 tons of grain. Such a low indicator indicates an insuﬃcient level of intensity of the industry, especially in agricultural organizations.

An in­depth study of the production, economic and ﬁnancial results of the work of the corn industry was carried out on the example of the agricultural production cooperative “Progress-Vertelishki” of the Grodno region for 2016–2018. Considerable attention in the APC is paid to the cultivation of corn for grain. In 2018, corn accounted for up to 32 % of the gross grain harvest in this agricultural organization. Among the production and economic indicators, labor productivity occupies an important place, therefore, considerable attention is paid to it in the article. In the APC “Progress-Vertelishki” during the study period, positive results were obtained when selling corn grain: the sale of products turned out to be sustainably proﬁtable with ﬂuctuations from 41,3 to 83,1 %.

Identifying primary and secondary stakeholders, analyzing the functional regimes of higher education, it becomes possible to identify opportunities for conjugation and interaction between academic institutions around the world. By analyzing the decision-making system in specific national conditions and higher education institutions, it becomes possible to understand how could be established the interaction tracks between various stakeholders acting in various national environment, allowing to institutionalize the channels of international communication and expanding cooperation.
The problem of the formation and activity of monarchical organizations on the territory of Belarus in the early twentieth century in publications of the pre-revolutionary period
Authors: Trubchyk P. A.
Published: August 2022

The article analyzes the pre-revolutionary historiography of the monarchist movement as part of the political history of Belarus in the early twentieth century. The early researchers managed to collect and systematize extensive factual material about right-wing political organizations. At the same time, the analysis of the works of ideologists and leaders of political parties gives reason to believe that they were propagandistic and primarily aimed at fighting their political opponents.
About the formal-semantic abstraction levels of derivational chains of emotive verbs in the Russian language
Authors: Tretsiakova Yu. R.
Published: August 2022

The relevance of the systems approach in the science of language in recent decades has led to the popularity of studying complex units of the word formation system (word-formation pairs, type, paradigm, chain, nest). The article is devoted to the description of the word-formation chain as a syntagmatic derivational structure organized by the stepped formation of each derivative in a certain word-formation way. The phenomenon of through-the-stepped word formation is described, which results in omission of a motivating lexeme and indicating the incompleteness of the derivational chain. The paper lists the criteria for typing and abstraction of word-formation chains within the LSG of emotive verbs. According to the degree of abstraction the hierarchy of derivational chains is presented: specific, typical, categorical word-formation chains. The author of the article draws attention to the need to single out an even more typified association of word-formation chains, based on the equal-thematic nature of word-formation meanings – supercategorical word-formation chains. These structures represent an invariant derivational model typing categorical derivational chains of one LSG. The paper notes the need to highlight such abstracted word-formation models as a means of ordering the derivational system of the language.

Published: August 2022

Low long bean productivity is one of the impacts of S. litura. Farmers often rely on chemical fertilizers to control the population of S. litura so that this control method can leave residues in the growing media. Therefore, an effort to overcome the problem of S. litura is to use natural pesticides from beluntas leaves (P. indica), which produce secondary metabolites. This study aimed to determine the effect of ethanol extract of beluntas (P. indica) leaves on the mortality of second instar larvae of S. litura in long bean plants. This study used a completely randomized design (CRD) consisting of 5 concentrations, namely 50 ppm, 100 ppm, 150 ppm, 200 ppm, and 250 ppm, as well as control using distilled water with two repetitions. Descriptive statistics analyzed the research data. The results showed that the ethanol extract of beluntas leaves affected the mortality of the second instar larvae S. litura by 40.0% at a concentration of 250 ppm. Concentrations of 50 ppm and 100 ppm gave a mortality effect of 10.0%, a concentration of 150 ppm was 15.0%, and a concentration of 200 ppm was 35.0%. Thus it can be concluded that the higher the concentration of the ethanol extract of beluntas leaves, the higher the mortality of the second instar larvae of S. litura.

The parameters observed in Green mustard growth were plant height, number of leaves, wet weight, leaf area, and dry weight. The results of the research showed that the POC of tofu waste, EM4, and its combination did not have a significant effect on all parameters.
Covid-19 wage subsidy support and effects
Authors: Hyslop Dean R. , Maré David C.
Published: August 2022

This note provides a brief preliminary analysis of the short run impact of COVID-19 and the government’s Covid Wage Subsidy (CWS) response on labour market flows. We focus on two issues. First, to examine the selectivity of the CWS, we describe the characteristics of firms and of workers who did and did-not receive subsidy payments. Second, to gauge how the pandemic and the CWS affected the labour market, we describe two aspects of the adjustment process: the job-turnover rates for workers in subsidised and non-subsidised firms; and trends in the transition rates between non-employed in subsidised and non-subsidised employment. We find that there was a larger drop in job turnover rates in subsidised than non-subsidised firms, but the excess turnover in subsidised firms had return to pre-lockdown levels by September, while that in non-subsidised firms remained low.

Published: August 2022

El objetivo de nuestra investigación es identificar los componentes químicos y evaluar in vitro, la actividad antibacteriana de los extractos de las hojas de Cupressus sempervirens L. y Cupressus arizonica L. del norte de Argelia contra Pseudomonas aeruginosa ATCC 9027. La extracción se realizó macerando las hojas en disolventes de polaridad creciente (cloroformo, éter de petróleo y metanol acuoso). Se realizó un cribado de los compuestos fenólicos para una caracterización cualitativa de los distintos extractos. Los extractos obtenidos se pusieron en contacto con una cepa de P. aeruginosa para determinar su potencial antibacteriano. El cribado fitoquímico reveló la presencia de varios metabolitos secundarios: leucoantocianinas, flavonoles, flavononas, antraquinonas, taninos catequicos, taninos gálicos, esteroides, triterpenos, saponina, glucósidos cardíacos, terpenoides, saponósidos y quinonas libres. El metanol acuoso (de alta polaridad) permite la extracción de la mayoría de los metabolitos. El mejor rendimiento de extracción de los tres disolventes es el cloroformo, con un rendimiento de extracción de 61.23% (C. sempervirens) y 52.27% (C. arizonica), seguido del disolvente hidroalcohólico 33.55% y etéreo con 0.39%. La extracción hidroalcohólica induce una sensibilidad muy importante de P. aeruginosa con un diámetro de 16.2 mm para C. arizonica. Extractos etéreos y clorofórmicos inducen una inhibición débil. P. aeruginosa es extremadamente sensible al extracto hidroalcohólico de C. sempervirens, este último induce una zona de inhibición con un diámetro de 19.95 mm que es estadísticamente igual a la inducida por la Vancomicina. Estos resultados pueden considerarse como una solución prometedora para la sustitución de la vancomicina por el extracto hidroalcohólico de C. sempervirens.

Published: August 2022

Mangroves (stretch of intertidal tropical and subtropical forests between inland coastal forests and the sea) are being exploited at a rate that is unprecedented, there is loss of biodiversity because of conflicting and unsuitable uses. This study was aimed at promoting the protection of mangrove and associated coastal forests within Tiko and Limbe III municipalities in south western Cameroon, Central Africa via the contribution of buffer zone agroforestry. Representative traditionally dominant agricultural land use sites were surveyed for the identification and analysis of farming practices using participatory rapid appraisal (PRA). Data collected (qualitative and quantitative) were subjected to descriptive and inferential statistics. Out of twelve (12) agroforestry practices currently carried out by farmers under three widely dominant classic agroforestry systems (agri-silvicultural – plantation and non-plantation, silvo-pastoral and agri-silvo-pastoral systems), 5 of them under plantation and non-plantation systems (palms on crops lands, cocoa-based, rubber on crop lands, scattered trees on farmland and home gardens) were considered climate smart agroforestry practices. The maximum diameter, density, height and crown diameter of trees were dominant in the cocoa-based except for the mango-based which had the maximum tree height. The tree size class for poles (≥10cm to <30cm) was dominant in the 5 practices. For a more inclusive green economy and climate smart agriculture, some improvements on tree density, shade management and choice of multi-purpose trees species (Cedrela sepium, Moringa oleifera, Leucaena leucocephala and fruit trees) for vital functions such as firewood, soil improvement, medicine, food and construction are advocated to enhance sustainable exploitation of adjacent coastal forests thus protecting mangrove. Moreover, on account of resultant stable tree species, structural and use diversity of adjacent coastal forests, further make buffer agroforestry to hold promise for the conservation of fragile and vulnerable mangroves. There is therefore also need to expand the present study in other mangrove areas especially the mangroves of Cameroon Estuary which is the major deforestation hotspot in Cameroon.

The Angiosperms are the best known and most diversified group in Senegal. However, even if a lot of work has been done on this group, more needs to be done. The main objective of this work is to contribute to a better knowledge of the biodiversity of dicotyledons in Senegal. More specifically, this work seeks to propose a determination key for the families of dicotyledons in order to facilitate their identification. Based on bibliographical research, a rough table and a summary table listing the different characters of the vegetative and reproductive systems of the families of the Dicotyledons of Senegal have been drawn up. These tables were used to propose dichotomous keys. This work made it possible to propose determination keys essentially based on the stable characters of the vegetative and reproductive systems of these families.

Powders of copper, zinc, manganese-substituted tricalcium phosphates (TCP) were synthesized, the composition and structure of the obtained compounds were studied. It is shown how copper, zinc and manganese ions affect the phase composition and microstructure of powders substituted with TCP. Composite materials based on a blend of polyvinylpyrrolidone with alginate (PVP:ALG) containing copper, zinc, and manganese-substituted TCP have been obtained. The thermal stability and mechanical strength of composite films crosslinked with polyvalent metal ions have been studied. The least strong, but at the same time more thermally stable composites crosslinked with alkaline earth metal ions. The test for cytotoxicity of powders substituted TCP’ extracts and composites showed that the powders and composite materials with them are non-toxic and biocompatible. The study of the antibacterial activity of the materials against the Escherichia coli C600 strain showed that the growth of bacteria was inhibited by the samples containing copper-TCP and zinc-TCP. The composite with manganese-TCP showed no activity against Escherichia coli C600. Composites based on the PVP:ALG blend with copper, zinc-substituted TCP can be considered as materials with an antibacterial effect for use in medicine.

The results of a study of the effect of the various types of fillers concentration at the nanoscale level, zinc stearate, aluminum, technical carbon — on the physical and mechanical properties of nanocomposites based on polyolefins are presented. High density polyethylene, low density polyethylene and polypropylene were used as polyolefins. In order to improve the compatibility of polyolefins with fillers, a copolymer of high density polyethylene with maleic anhydride was used as a compatibilizer. The amount of maleic anhydride in the high density polyethylene was 5.7 wt %. Investigated such properties of nanocomposites as ultimate tensile stress, tensile yield strength, elongation at break, static bending strength and Vicat heat resistance. It was found that the use of a compatibilizer contributes to a significant improvement in the main physico-mechanical characteristics of nanocomposites, which indicates the technological compatibility of the mixed components of the mixture with the polymer matrix. It was found that in the presence of fillers, the elongation at break of the nanocomposites slightly decreases. It is shown that an increase in the content of technical carbon in the polymer matrix in the presence of 5.0 wt % concentration of aluminum is accompanied by an increase in the ultimate tensile stress and yield stress during stretching of nanocomposites with a maximum at a certain ratio of the mixture components. It was found that in polyolefins characterized by a relatively high degree of crystallinity, the maximum value of the ultimate tensile stress is achieved at a lower concentration of technical carbon.

Published: August 2022

Goals. The main purpose of this work is to develop a methodology for determining the parameters of binary signals, at which the signals become relatively invariant to frequency distortions in the marine environment. The frequency distortion of the signals is caused by the uneven frequency response of the attenuation of the marine environment. The main part of this technique is to assess the effect of frequency distortion of signals on the noise immunity of reception. In accordance with this, the error probabilities of signal receivers with various types of manipulation are determined, which are optimal in the absence of errors. Methods. The provisions of applied hydroacoustics, the theory of random processes and the theory of transmission of discrete messages are used. The main content. The paper considered a model of a single-beam hydro-acoustic communication channel, characteristic of the deep sea, when the receiver or transmitter is located in the depths of the sea. The transmission coefficient of the channel is used as a transmission coefficient with a Gaussian amplitude-frequency characteristic and a linear phase-frequency characteristic. The error probabilities of coherent binary signal receivers with amplitude, frequency and phase manipulation with a rectangular envelope are determined. Coherent receivers optimal by the criterion of maximum likelihood under the action of white Gaussian noise and the absence of distortion in the marine environment are considered as receivers. A logarithmic measure of increasing the probability of error is introduced, which characterizes the deterioration of noise immunity due to frequency distortions in the channel. For some typical cases, the values of signal parameters are determined that are relatively in-variant to frequency distortions in the marine environment. Results. Expressions of the error probability of coherent binary signal receivers with amplitude, frequency and phase manipulation with a rectangular envelope are found. A logarithmic measure of the relative increase in the probability of error compared to the case of no distortion is introduced. The functional dependence of this measure on the duration of the signal transmission, the carrier frequency and the initial phase of the signal, as well as on the communication distance and the signal-to-noise ratio is determined. On the plane of the carrier frequency, the duration of the signal, for each type of signal, a boundary of the region is constructed, above which the signals are relatively invariant to frequency distortions in the marine environment. For communication ranges R = 1.5 km and 3 km and typical carrier frequencies, the minimum values of the duration of invariant signals are given.

Published: August 2022

Science events are encountered in every phase of daily life. These science events can be encountered at home, in business life, or while studying at school. Human beings can learn about these scientific events both informally and formally. Science-related events can often be confusing, even when formally learned. This study, it was aimed to develop a CRPS to investigate whether they learned some science events correctly in daily life. The study was carried out on 313 people from different age and occupational groups living in Edirne, Turkey. To develop a scale, statistical data such as item-total correlation (rit) and item-remainder correlation (rir) coefficients analysis, discrimination analysis, frequency and % values for the answers given by the participants to the items, t-test, Rulon and Cronbach Alpha coefficient transactions have been made. The scale, which started with 35 items, was reduced to 30 items due to the analysis. Cronbach Alpha and Rulon reliability coefficients were found to be 0.85 and 0.87, respectively. It was understood that the scale showed a symmetric-homogeneous distribution. According to these data, it has been determined that some scientific events in daily life can be measured with the knowledge-based approach.

Objetivou-se analisar uma intervenção de cuidado integral em saúde bucal de abordagem comunitária protagonizada por residentes de Odontologia em Saúde da Família inseridos em duas unidades de saúde do campo de Caruaru/PE, segundo o olhar de profissionais, residentes e usuários. A intervenção englobou diagnóstico e levantamento das necessidades odontológicas, ações coletivas em saúde bucal e ações assistenciais para cárie com tratamento restaurador atraumático. Os grupos-alvo formam escolares e moradores de áreas mais remotas nas unidades de Lagoa de Pedra e de Xicuru. O estudo qualitativo utilizou técnica do grupo focal para coleta dos dados. Três grupos foram constituídos: nove profissionais, seis residentes e oito usuários. As entrevistas seguiram um roteiro com perguntas abertas sobre o cuidado e as tecnologias em saúde bucal empregadas no contexto das populações campesinas e acesso/acessibilidade às unidades de saúde. Os dados foram submetidos à análise de conteúdo. Emergiram duas categorias temáticas: dificuldades de acesso aos cuidados em saúde bucal e satisfação com as ações implementadas. Os participantes dos três grupos avaliaram positivamente a iniciativa de estabelecer relação educativa/assistencial participativa abrindo se a espaços comunitários e valorizaram o enfoque adotado pela intervenção de saúde bucal no enfrentamento dos problemas limitadores do acesso aos serviços odontológicos e às ações coletivas que relataram. Contudo, desinteresse na continuidade das ações realizadas e contrários às práticas comunitárias em saúde bucal foram relatadas no grupo focal dos profissionais. Considera-se persistir fatores profissionais e de estrutura limitadores à garantia dos direitos de acesso à saúde aos usuários de áreas mais remotas às unidades de saúde.
