This article discusses how the category of argumentativeness is employed in online movie reviews written in English. The objectives of the study were to consider the concepts of argumentation and argumentativeness, to define the categories of argumentativeness and evaluativeness as the constituents of a movie review, as well as to identify the lexical-semantic, stylistic, and structural-syntactic parameters of the argumentative discourse expressed in an online movie review. The validity and reliability of the ways used to process the material under study were ensured by the correct application of the following modern methods of linguistic analysis: structural-semantic, interpretative, and functional-stylistic. A number of examples were provided, all proving that the development of the author’s thesis occurs both explicitly (owing to the presence of the thesis and at least two arguments, linking words, introductory phrases, parenthesis) and implicitly (through to the question-answer form of presentation, irony, sarcasm, and using of numerous personal pronouns). The results obtained show that conjunctions play a significant role in the development of the argumentative discourse: firstly, coordinating conjunctions (such as and, so, but) introduce the thesis; secondly, subordinating conjunctions (for example, because, since, as) introduce arguments serving to put forward the thesis. It was concluded that the argumentative discourse in the text of a movie review explicitly manifests itself through such lexical means used to express the category of cohesion (transition from one segment to another while maintaining both structural and semantic unity) as in the first place, for example, then, plus, finally, etc. It was also revealed that any “incorporations” of other discourses, which are markers of a causal interdiscursive strategy, have an argumentative potential in the text of a movie review and fall into two categories: references to the director’s previous works; references to films of other directors. The results of this study are important for developing modern genre studies and the theory of speech acts.

This article considers the major problems that arise when the key terms used in psycho- and neurolinguistics are interpreted and translated into a foreign language. The diversity and ambiguity of psycho- and neurolinguistic terms can create difficulties in, for example, the translation of the works of famous Russian psycholinguists. Here the fragments of the official translations of T.V. Akhutina’s works that cover the Leontiev–Akhutina concepts going back to L.S. Vygotsky’s ideas are discussed. These works focus is on the terms smysl (‘sense’) and znachenie (‘meaning’), both of which cause substantial problems for translation. To define how the authors understand them and create an adequate translation, the theory explained in the works must be studied thoroughly and carefully. The analysis of contextual usages reveals the corresponding and controversial variants of these terms in English that occurred as a result of their translation.

This article describes the results of an attempt to examine the auditory and speech abilities of children with learning difficulties using online tests. A total of 307 children (1 to 7 graders), all facing problems while writing and reading, took part in the experiment. The consistency of auditory and speech tests performed during the neuropsychological and speech therapy practices was analyzed. The following tests were selected: memorizing 10 words, repeating syllables with oppositional consonants, and repeating desemanticized stimuli (nonwords). The results of the correlation analysis proved that the tests are consistent: there was a significant bond between the success of repeating nonwords, syllables, and memorizing 10 words. We also considered how different age groups of children with learning difficulties performed in the tests. Further prospects for studying the revealed patterns were outlined.

Cognitive development and bilingualism in preschool childhood have recently become the pivotal research issues. This article is a brief review of the major studies covering the problem of how bilingualism influences both cognitive development and academic success in preschool children, as well as whether bilingual education determines the development of executive functions. We paid special attention to the data obtained on the development of executive functions in bilingual and monolingual children that help to understand whether there are any differences between the two groups. Using the international citation databases, we identified the publications of the studies of cognitive development in children under the conditions of bilingualism. The results of the analysis were exported in the VOSviewer environment and visualized as key clusters. The findings of the Russian and foreign studies showing the ambiguity of the connection between mono- and bilingualism in children and their cognitive development were described and compared. Interestingly, the studies in preschool institutions of the Republic of Tatarstan (Russia) established that bilingualism has a positive effect on the cognitive abilities of children, if the anthropology of the linguistic personality (types of bilingualism) and the multicultural conditions of language interference and transposition are taken into account.

Пуск трубопровода после временной остановки может быть сопряжен со значительными трудностями, особенно в случае перекачки неньютоновских нефтей со сложной реологией. Это обусловлено тем, что в процессе остывания нефти (во время остановки) давление страгивания, определяемое через касательное напряжение сдвига, может превысить допустимые значения давления на линейной части трубопровода и/или допустимый напор на выходе нефтеперекачивающей станции. Как правило, при оценке распределения температуры нефти вдоль оси трубопровода пренебрегают изменением температуры в радиальном направлении. При этом учет данного параметра должен повысить точность определения касательного напряжения сдвига, давления страгивания и времени безопасной остановки трубопровода. В настоящей статье для описания начального этапа запуска остановленного «горячего» трубопровода используется гидравлическая постановка и частное решение базовой системы уравнений в виде бегущей волны одного направления. Постановка задачи включает учет радиального распределения температуры, неньютоновской реологии нефти и кинетики переходного процесса ее структурирования. В отличие от квазистатического давления сдвига, отождествляемого с минимальным давлением запуска остановленного «горячего» трубопровода, предлагается рассматривать давление в начальном сечении бегущей волны одного направления.

Pipeline start after shut-off can be connected with essential difficulties, especially in case of pumping non-Newtonian oils with complicated rheology. This is caused by the fact that during oil cooling (during shut-off) the starting pressure defined through shear stress can exceed allowable pressure values in the pipeline linear portion and/or allowable head at the oil transfer pumping station outlet. Normally, when evaluating oil temperature distribution over the pipeline axis, temperature variation in radial direction is neglected, and average oil temperature in each route point is used. At that consideration of this parameter shall increase the definition accuracy for the shear stress, starting pressure and time of pipeline safety shut-off. In this paper hydraulic statement and partial solution of the base system of equations in the form of a single-direction running wave are used for description of the initial stage of shutdown “hot” pipeline start. The problem statement incorporates consideration of temperature radial distribution, non-Newtonian oil rheology and its structuring transient kinetics. In comparison with a quasi-static shear pressure, which is identified with the minimum pressure of shutdown “hot” pipeline start, it is offered to consider the pressure in the initial section of the single-direction running wave.

Published: July 2022

Carbon emissions from the burning of fossil fuels and greenhouse gas emissions induce global warming which is a serious and challenging environmental threat in the contemporary era. By applying time series data and analyzing through econometric techniques, such as unit root tests, bound techniques, ARDL techniques and causality techniques, this article examines the impact of economic growth, financial development, and energy consumption on CO2 emissions over the period 1990 to 2019 in Sri Lanka. According to the study’s conclusions, all variables are cointegrated in the long run. The causality analysis reveals that unidirectional causality runs from environmental degradation to financial development and environmental degradation and energy consumption, whereas bidirectional causality is found between financial development and energy consumption in the long run. Further, the findings revealed that energy consumption and financial development have a statistically significant positive impact on environmental degradation in the long run as well as the short run. Financial innovation should be stimulated throughout the country to meet requirements for long-term development. Further, the development process should be progressed through carbon trading technology, energy structure optimization, and energy consumption efficiency promotion.

Church run institutions face a host of challenges in their quest to execute their mandate. This study sought to analyse the challenges faced by church run institutions in Zimbabwe. The study investigates some critical challenges faced by church run teachers’ colleges in Zimbabwe. The study employed a manifold case study research design to allow for an in-depth study of phenomenon. Three church run teachers’ colleges were studied as they offer rich insights on the study under review. The research study used an interpretivist paradigm which is located in the qualitative approach. The interpretivist paradigm is concerned with understanding the world as it is from experiences of the informants. The paradigm was the most suitable for this study as it allowed for the researcher to use qualitative data collecting techniques such as interviews, focus group discussions and document analysis. This study used a purposive sampling technique as it allowed selection of informants with rich experiences of (CRTCs), subsequently, three principals, three student representative councils, three Church Education Secretaries and three human resources (HR) officers were selected to participate in this study. The study showed that the interplay of following bodies namely education Boards, advisory councils, church main councils, the University of Zimbabwe and the Ministry responsible for tertiary institutions pose a potential challenge as managers of these church run institutions grapple with a seemingly a surmountable task to satisfy the needs and interests of each entity. The results also showed that the existing policies and procedures of both the responsible authority and the ministry pose a challenge as both entities have their own expectations which they would not want compromised. From the findings, there is a worrying factor with regards to recruitment of staff, as the church, whenever there is a vacancy especially for lecturers, they would naturally want to have somebody from within their system. The church would want their members to be given an opportunity above other competitors and that disturbs the way the institution is run because management will want the best qualified person. So, nepotism was identified as a big challenge for the institution that leads to another challenge of labour issues. The study concluded and recommended engagement of all stakeholders including the student body in the management of church-run teachers’ colleges.

A atividade mínima detectável (AMD) representa o valor mínimo de atividade que é detectada em um sistema de monotoração. Existem diversas metodologias que podem ser utilizadas para calcular a AMD, no entanto os resultados para cada uma destas podem ser divergentes. Laboratórios de dosimetria interna in vivo devem dispor deste parâmetro para cada tipo de geometria de contagem, bem como, para cada tipo de radionuclídeo de interesse, visando a otimização do processo de monitoração interna. O objetivo deste trabalho foi comparar três tipos de metodologias de cálculo utilizadas na determinação da AMD com os resultados obtidos experimentalmente. As metodologias de cálculo utilizadas foram as sugeridas por Currie (1968), a publicada em Health Physics Society N13.30 (1996) e a ISO 11929 (2018). A monitoração de um phantom de cabeça contendo na região correspondente ao cérebro 18F-FDG foi realizada para a obtenção da AMD experimental. Os resultados obtidos para os valores de AMDs utilizando as três diferentes metodologias apresentaram diferenças de acordo com as faixas de atividades analisadas. As incertezas do fator de calibração e Background do sistema são os principais parâmetros entre as três metodologias de cálculo que influenciaram nos resultados obtidos.

Published: July 2022

Study in hand is planned to dig out the important segment of society i.e. Demographic Dividend that is an accelerating force for socio-economic development. Demographic Dividend is a situation in which working age population increased and dependency ratio is decreased. This working force is a human capital for any state, its meticulous utilization through labor force participation brings development in state. The demographic dividend is a phase of high socio-economic acceleration that associated with the low fertility and mortality rate and the specially working age group of population is prominent. Developed and industrial countries utilize this demographic transition and used the productive age group for the development of the countries in the form of labor force participation, social capital and human capital development. But the developing countries face the issues that are associated with the demographic dividend such countries do not use their youth potential for the socio-economic development, and facing the problems of population burden. The major concern of the study is to explore the reasons behind the demographic transition and utilization of existing working age population for the sake of development in social and economic sphere by developing human Capital and labor force participation. Study in hand was conducted in three districts Rawalpindi, Faisalabad and Multan from geographically dividend zones of Punjab, Pakistan. 520 respondents sample was selected with the help of Taro Yamani formula. Mediation analysis performed for explaining the relationship among different variables that shows a significant association. Inferences depicts that Pakistan currently had a window for opportunity in the form of demographic dividend. Dividend can only be achieved through utilization the potential of youth by forming human capital in the form of skill development and inclusion of youth into labor market.

Published: July 2022

Experimental study was conducted to determine the effect of velocity of axial fan, outlet vent height, position, area, and aspect ratio (h/w) of ventilated enclosure on convection heat transfer. Rectangular wooden ventilated enclosure having top and front transparent wall was made up of Perspex for visualization, and internal physical dimensions of box were 200 mm × 200 mm × 400 mm. Inlet vent was at bottom while outlet vents were at the side and top wall. Electrically heated cylindrical heat source having 6.1 slenderness ratio was fabricated and hanged at the centre of the enclosure. To calculate heat transfer rates, thermocouples were attached to the inner surface of heat source with silica gel. Heat source was operated at constant heat flux in order to quantify the effect of velocity of air on heat transfer. It was observed that average Nusselt number was increased from 68 to 216 by changing velocity from 0 to 3.34 m/s at constant modified Grashof number i.e. 5.67E+09. While variation in outlet height at the front wall did not affect heat transfer in forced convection region. However, Nusselt number decreased to 5% by changing the outlet position from top to the front wall or by 50% reduction in outlet area during forced convection. Mean rise in temperature of enclosure increased from 8.19 K to 9.40 K by increasing aspect ratio of enclosure from 1.5 to 2 by operating heat source at constant heat flux i.e. 541.20 w/m2.
Aspectos morfológicos da Libras: reflexões necessárias sobre o processo de formação de sinais
Authors: Souza José Marcos Rosendo de , Lima Neto Izaías Serafim de , Peixoto de Lima Edmar
Published: July 2022

As investigações sobre os aspectos morfológicos relacionados à Língua Brasileira de Sinais (Libras) são relativamente recentes (consolidados a partir de 2004), quando comparados aos estudos da morfologia das línguas orais (a partir de 1968). O tardio interesse por essa área da linguística pode se justificar pelo reconhecimento também tardio da Libras no Brasil, tendo ocorrido somente no Século XXI, pela Lei 10.436 de 24 de abril de 2002. Sendo constatada como instrumento de comunicação e expressão das Comunidades Surdas Brasileiras, a Libras passou a ocupar diferentes espaços na sociedade contemporânea, sobretudo, no cenário acadêmico-científico. Nesse sentido, o presente estudo objetiva discutir os processos de formação de sinais da Libras, considerando sua modalidade linguística visuoespacial e, para isso, a investigação recorre, metodologicamente, aos preceitos de cunho bibliográfico, o que colabora para ampliar as pesquisas na área da morfologia da Libras. Os resultados deste trabalho apontam que é possível identificar os processos formativos, principalmente, do tipo “composição” e que, por se tratar de uma língua cuja modalidade é visuoespacial, os processos de formação de sinais (componente lexical da Libras) se distinguem daqueles identificados na língua oral.

Published: July 2022

O presente artigo faz parte de uma pesquisa de mestrado focada no estudo da produção escrita em guarani em contexto de fala castelhana na Universidade Indígena UNIBOL – Bolívia. Este estudo tem como objetivo analisar o léxico guarani utilizado em narrativas escritas em castelhano. Através de uma análise semântico lexical, procura-se focalizar nos possíveis critérios pelos quais aparecem certas construções lexicais em guarani em narrativas que predominantemente estão escritas em castelhano, assim como também quais podem ser seus possíveis significados. Este trabalho focaliza a questão de como os sujeitos constroem sua identidade históricocultural e linguística por meio do discurso e práticas sociodiscursivas e da seleção de seu repertorio lexical. A sustentação teórica de estudo está centrada em discussões sobre conceitos de léxico (BIDERMAN, 2001), (POLGUÊRE, 2018), palavra e tipos de palavra (ISQUERDO e OLIVEIRA, 1998), e sua relação com a cultura e identidade dos falantes (MATORÉ, 1953), (SAPIR, 1969), (SEABRA, 2015) entre outros estudiosos. Metodologicamente se procedeu a coleta do corpus por meio de um recorte dos léxicos em guarani, compilados em um glossário e posterior categorização, tomou-se como critério de seleção a frequência e o tipo de ocorrência do léxico. Os resultados indicam que a escolha do léxico reflete, na maioria das vezes, o caráter subjetivo do falante e pela seleção e manifestação do léxico as pessoas podem construir e reconstruir sua identidade linguística assim como também cultural.

Para a coleta de dados, utilizou-se o repositório de sinais do CAS/MS. Os dados obtidos foram classificados a partir dos estudos de Paales (2011) e a motivação para a criação dos sinais de nome foi resgatada por meio de entrevistas com professores surdos. Os resultados mostram que a maioria dos sinais analisados se encaixam na categoria inicialização e descrição. Além disso, as entrevistas realizadas evidenciaram que a experiência visual dos surdos e suas vivências na comunidade surda influenciaram a motivação da escolha toponímica. Como conclusões, depreende-se das discussões que os sinais de nome analisados apresentaram em sua maioria independência da taxionomia do seu nome próprio na língua oral.
“Ring” structures as a marking sign of the stress-strain state of the geo-medium
Authors: Miroshnikova L.K. , Mezentsev A.Yu. , Semenyakin N.V. , Filippova N.E.
Published: July 2022

Innovative solutions for identifying geodynamically active structures based on the morphostructural analysis of sedimentary deposits of the Tunguska series (Carboniferous-Permian), which are the upper level of the localization of ore-bearing massifs and rich sulfide platinum-bearing copper-nickel ores, are considered. The morphostructural groups of oval outlines identified on the isolinear distribution schemes of the top and bottom of the Tunguska series are considered as a marker of the “ring” structures development. These structures are developed along the boundaries of mine fields. Their formation took place in the period following the ore formation. Individual tectonic disturbances developed inside the “ring” structures and along their boundaries can be traced down to the occurrence depth of the ore-bearing intrusions and ore bodies. The “ring” structures were formed in the southwestern part of the Talnakh ore cluster as a result of left-sided strike-slip faults, which were accompanied by east-bound torsions. The “ring” structures are morphotectonic blocks that are distinguished by maximum tension indicators. As a result of the research, it was found that the “ring” structures are the marking signs of geodynamically active structures of the strike-slip and the oblique-slip kinematics with a high density of disjunctive disturbances, in which high risks in development of dangerous geodynamic processes and phenomena are possible in zones adjacent to the mine fields.

Application of digital twins to predict rock-bump hazard of drift pillars
Authors: Moroz N.E. , Sidorov D.V. , Sonnov M.A.
Published: July 2022

Drift pillars are used to protect haulage tunnels from the effects of formation pressure and ingress of the caved rock mass. At the same time, leaving pillars made up of fragile ores exposed to significant compressive stresses poses a risk of dynamic formation pressure. Due to the design features of the mining method and safety regulations, it is not possible to access the drift pillar from the rising side, which limits the ability to make a meaningful instrumental forecast of the rock-bump hazard. Therefore, it is advisable to use digital twins to predict the rock-bump hazard of the drift pillars. The article describes the experience gained by the VNIMI Institute in using the PRESS 3D URAL dedicated software (Polygore LLC, St. Petersburg) and the FIDESYS software package (Fidesys, Moscow) for a comprehensive assessment of the stress-and-strain state and rock-bump hazardous condition of the drift pillar. The first stage included numerical evaluation of the natural tectonic stress field using the PRESS 3D URAL software. At the second stage, an assessment of the man-made stress-and-strain state of the rock mass and the ore drift pillar was performed using the FIDESYS software package during underground mining with the heading-and-stall method. The final stage involved a prediction of the rock-bump hazard of the ore pillar using data on the ore strength properties.

The paper considers the fundamental principles of the study of the rheological features of the melt flow of the initial low-density polyethylene and its filled compositions with aluminum powder, depending on the filler concentration, temperature and shear rate. To improve the compatibility of metal-polymer systems, a compatibilizer was used, which is a graft copolymer of low density polyethylene with 5 – 7 wt. % maleic anhydride content. First, the values of the melt flow rate of low density polyethylene were determined depending on the concentration of aluminum powder. The filler concentration was varied in the range 0.5 – 30 wt. %. It is shown that with the loading of 0.5 wt. % aluminum powder, the maximum fluidity of the composites melt is achieved. The flow curves, the dependence of the effective viscosity on the shear rate of the initial low-density polyethylene and composites with 0.5 wt. % and 5.0 wt. % content of aluminum powder were determined. The theoretical substantiation of the regularities of changes in rheological properties is given. The regularity of the change in the effective viscosity of the melt on temperature in Arrhenius coordinates has been established. On the basis of the curves obtained, the values of the activation energy of the viscous flow are determined. It was found that with the loading of the filler, an increase in the activation energy of the viscous flow is observed. A temperature-invariant characteristic of the viscosity properties of composites has been constructed, which makes it possible to predict the change in the value of this indicator at high shear rates, close to their processing by extrusion and injection molding. The developed materials have passed industrial testing at the METAK LLC enterprise in Azerbaijan.

There was analyzed the distribution uniformity of reinforcing particles Ti2NbAl in composite materials (CM) based on aluminum alloy AO20-1, made by mechanical mixing. Samples with different structure dispersion were obtained by crystallization of a composite melt in molds made of materials with different thermal conductivity. There were used methods of digitizing the structure microphoto and mathematical statistics to estimation structural heterogeneity. Based on the results of processing the photographic images, there were constructed histograms of the frequencies of the distribution of intermetallic particles in the matrix. It is revealed that matrix structure refinement has positive effect on uniformity of the distribution. A significant decrease in the coefficient of variation for specimens with a finer structure also indicates a more uniform distribution of the reinforcing phase in this specimens. There was compared a wear resistance of the material and the uniformity of distribution of the Ti2NbAl powder in the matrix. A wear rate of composite materials was determined by testing on CETR UMT Multi-Specimen Test System under dry sliding friction conditions with sequential stepwise axial loading to values of 0.5, 1, 1.5, 2, 2.5, 3 MPa, at constant sliding speed of 0.5 m/s. The test time for each axial load was 2000 s, the friction path was 6000 m. It was observed a significant reduction in weight loss during friction for all CM samples as compared to the matrix alloy. The wear rate of CM specimens with a better distribution of the reinforcing component is reduced by more than 2.7 times as compared to specimens from the AO20-1 alloy, and with a less uniform distribution by 2.2 times

The purpose of the work is to obtain microwave absorber materials based on Fe – Al particles and to study its absorbing characteristics. Composite materials consisting of Fe, Fe – Al particles and a paraffin matrix were obtained by rotational magnetic field method. The mechanism of the field of rotational magnetic dipoles usage for Fe particles coating with Al nanoparticles and further composite material synthesis was described. Microstructure, mechanical, magnetic and dielectric properties and parameters of microwave absorption of obtained composite materials were investigate. Magnetic and dielectric permittivity in the frequency range 8 – 12 GHz were obtained. The influence of the field of rotational magnetic dipoles in combination with Al nanoparticles allows to obtain more durable structure in comparison with composite materials without Al nanoparticles. It was found that composite materials have a good radio-absorbing properties in the studied frequency range. The maximal value of S21 = –27,9 dB was obtained on 12 GHz frequency for a Fe – Al composite material with the field of rotational magnetic dipoles application.

The paper presents calculated data on a comparative assessment of the radiation-protective properties of materials based on titanium hydride, obtained by the method of multigroup modeling of protection against neutron and gamma radiation. Two types of compositions behind the steel reactor vessel and lead shielding are considered. It is shown that gamma radiation behind the protection of titanium hydride is formed by capture radiation arising in the initial layers of the protection. Secondary gamma radiation generated during the passage of a neutron flux through the thickness of the composite does not have a noticeable effect on the value of the functionals of gamma quanta behind the shield. The high efficiency of materials based on titanium hydride shot is shown. Behind the protection of a composite based on titanium hydride shot 1 m thick, the dose rate of fast neutrons is three orders of magnitude lower, and the dose rate of gamma rays is two orders of magnitude less than behind serpentinite concrete. The introduction of boron atoms into the composition of the composite, which has a large neutron absorption cross section in the thermal and suprathermal regions of the spectrum, reduces the effect of accumulation of thermal neutrons and the level of captured gamma radiation, but does not affect the attenuation of fast neutrons. The necessity of using titanium hydride shot on a cement binder is shown, which prevents the formation of voids in the protection structure and the gap of neutrons.

The properties of quartz flour, glass balls and basalt powder as fillers of an epoxy-anhydride compound are investigated, the values of thermal conductivity of filler powders obtained by the probe method on the MIT-1 device according to GOST 30256 are presented. The rheological properties of the components of compounds A and B, as well as the corresponding mixed compositions on the MCR-92 device were studied. The cured compounds were characterized by thermogravimetry and differential scanning calorimetry on the STA 449F3 Jupiter (NETZSCH) device. Using the Fluke PM 6303A RLC meter, data on the frequency dependence of electrical resistance and physical and mechanical properties of compounds were obtained using the Shimadzu AGSH bursting machine (Japan). It is shown that the nature of the filler determines the properties and formation of the polymer-filler interface as one of the key components of the composite material. Data on the influence of the nature of fillers on the operational properties of filling compounds are obtained.

The aim of the study is to determine the features of the formation and functioning of phraseological units containing borrowings from the Russian language in the dialects of the Russian Germans. The article analyses the use of direct borrowings as a part of phraseological units and also reveals the mechanism of calquing, in which the structure and semantics of the corresponding Russian phraseological units are conveyed by means of the German dialect. The scientific novelty lies in describing the features of phraseological units containing borrowings in their composition in insular Russian-German dialects. As a result, it has been proved that the most typical is the use of direct borrowings as separate components of phraseological units; borrowings can act as a basic element of a phraseological unit or a secondary element that clarifies the meaning of an idiom.
