Authors: Yekini Nureni Asafe , Adigun Oyeranmi , Akinwole Agnes Kikelomo 
Published: January 2023

The January 2022 edition of webometric ranking placed Yaba College of Technology as number one from 152 polytechnics in Nigeria. The ranking weight is 66 for country ranking, 8162 world ranking, Impact, Openness, and Excellence of 9698, 4558, and 7190 respectively. The negative variation and low webometric ranking of Yaba College of Technology that happened to be the first higher institution of learning in Nigeria with the slogan the first and still the best is a point of concern and motivates this research work. This research work collected data to evaluate the indicators for webometric ranking among the students and staff of Yaba College of Technology, a total of 346 were sampled students 44.51 % and Staff 55.49 %. The discussion and analysis of data obtained revealed that the poor webometric ranking is due to inadequacy of the necessary ICT infrastructure to encourage robust web presence; non-availability of up-to-date and scanty content on the Polytechnics website; Non-frequent usage of the Polytechnic website by the staff and students of the Polytechnic; the inadequate number of external networks (subnets) links with Polytechnic website; insufficient number of the top-cited publications in high impact Journals from the staff of the Yaba College of Technology; and Scanty number of the profile of staff from the Polytechnic on Google Scholar and ResearchGate, etc. among others. This research work opined that low webometric ranking could result in the following negative impact on the polytechnics lowering the esteem of the Polytechnic in the eyes of stakeholders, potential students and funding agencies, academic exchange with reputable institutions from other parts of the world for teaching, learning and research may writhe. The consequence of our findings recommendations was made to improve webometric ranking in future.

The object of research is the mechanization of the process of eliminating emission funnels on the earth's surface, formed as a result of explosions of shells and rockets.
The problem being solved in the work is related to the military operations on the territory of Ukraine, because of which thousands of hectares of land appeared, disturbed as a result of explosions of shells and missiles, excluding their further effective use without restoration. The first step in the restoration of such lands is backfilling by means of mechanization, however, due to the different sizes of the formed emission funnels, there is no universal equipment for achieving the set goals.
In the course of the work, the main types of disturbances of the earth's surface, formed as a result of the explosion of shells, represented by emission funnels in open areas, were determined. It has been established that the number of disturbed soil layers as a result of the formation of a funnel depends on its depth. Efficient methods of mechanization of backfilling of emission funnels in accordance with their parameters are proposed. Schemes of five main types of emission funnels are presented, taking into account the number of soil layers disturbed as a result of the explosion, which make it possible to determine the sequence of restoration of disturbed areas of the earth's surface.
It has been established that the dependence of the volume of emission funnels on their depth is a power law, while the angle of inclination of the slopes also has a significant effect on the value of the funnel volume. It has been determined that with an increase in the funnel depth from 1 to 10 m, its volume increases from 350 to 450 times depending on the funnel slope angle, and an increase in the funnel slope angle by 28 % from 35° to 45° leads to an increase in its volume by 95 %, and the area by 98 %.
The recommendations developed in the work on the choice of mechanization means for the elimination of emission funnels formed as a result of explosions of shells and rockets, depending on the depth of the funnel, can be used in practice. The established dependences of the required time for backfilling the emission funnels on their depth can be used for a preliminary assessment of the cost of restoration work, depending on the chosen means of mechanization and the volume of emission funnels.
Motû nas narrativas do Ciclo de Ba’lu e Anatu e seus possíveis reflexos na Bíblia Hebraica
Authors: Pedrosa Douglas De Souza 
Published: January 2023

O Ciclo de Ba’lu e Anatu foi preservado em seis tabletes de argila e é composto por três narrativas. Esses mitos, classificados por KTU 1.1-6, fazem parte dos textos mitológicos encontrados em Ugarite. À vista disso, buscou-se, neste trabalho realizar uma discussão sobre a origem de Deus Motû nos textos de Ugarite e suas possíveis reverberações nos textos da Bíblia Hebraica. Para conduzir esse introdutório estudo, em princípio dialogamos com bibliografias que nos possibilitam identificar as características do Deus Motû e sua presença nos textos de Ugarite. Consequentemente, a partir disto, restringimos o estudo à duas questões, especificamente: a influência que o Deus Motû possui nas narrativas mitológicas do Ciclo de Ba’lu-Anatu e, por fim, a possível correlação entre Motû dos textos de Ugarite e a expressão mawet na Bíblia Hebraica.

Aim. To identify predictors of rethrombosis and death in patients with coronavirus disease (COVID-19) after thrombectomy for acute lower limb ischemia.Material and methods. For the period from April 2020 to January 2022, 189 pa tients with acute arterial lower limb thrombosis and acute lower limb ischemia were included in this study. In all cases, a positive polymerase chain reaction test for SARS-CoV-2 was obtained. According to chest multislice computed tomography, bilateral multisegmental pneumonia was identified as follows: 76 patients — grade 2 (25-50% of lung tissue involvement); 52 patients — grade 3 (50-75%); 61 patients — grade 4 (>75%). Breathing was carried out as follows: in 88 patients — spontaneous; in 42 — with oxygen administration by nasal cannula; 26 — non-invasive ventilation; 33 had artificial ventilation. All acute arterial thromboses developed within the hospital at 4,5±1,5 days after hospitalization. The time between the onset to diagnosis verification was 27,8±5,0 min. The revascularization strategy was established by a multidisciplinary team meeting. The interval between the development of acute ischemia symptoms and surgery was 45,9±6,3 minutes. Thrombectomy was performed according to the standard technique, under local and/or intravenous anesthesia, using 3F-7F Fogarty catheters.Results. Retrombosis developed in 80,4% of cases 6,4±5,1 hours after surgery. In 59,8% of cases, retrombectomy turned out to be ineffective and the patient underwent limb amputation. In 65,6% of patients, a death was established due to multiple organ dysfunction. Among them, limb amputation was performed in 103 patients. Binary logistic regression identified following predictors of retrombosis/ death: age over 70 years (odds ratio (OR), 30,73; 95% confidence interval (CI), 11,52-33,7), obesity (OR, 15,53; 95% CI, 6,41-78,19), diabetes (OR 14,21; 95% CI, 5,86-49,21), vasopressor support (OR 8,55; 95% CI, 4,94-17,93), mechanical ventilation (OR 7,39; 95% CI, 4,81-16,52).Conclusion. Predictors of retrombosis and death in patients with COVID-19 after lower limb arterial thrombectomy are age over 70 years, obesity, diabetes, vasopressor support, and mechanical ventilation.
On the cause of ground stress tensile pulses observed before the 1976 Tangshan earthquake

Published: January 2023

Abstract
It has been asserted that earthquakes cannot be predicted (Geller et al., 1997). This may be true to some extent for the present, but it should not stop further research. The discussion of stress changes in this article gives an example to show that what people observe near the surface may not be the situation at depth. Nonetheless, such surficial observations reflect the movements of the crust associated with earthquakes.
Before the great M 7.8 Tangshan, China, earthquake in 1976, the Douhe and Zhaogezhuang stress-monitoring stations on the supposed fault zone observed significant tensile pulses of ground stress normal to the fault zone. The data are both reliable and reasonable. Analysis of the stress field adjacent to a fracture front shows that, when the fracture front passes by the measuring point, the stress normal to the fracture will first rise and then drop, while the stress at an angle of 30° to the fracture has much less significant variation in the observations. The pulses are attributed to the near-surface tensile fractures generated along the fault zone.

Published: January 2023

The aim of the study was to identify the features of the somatometric parameters of Yakut men in the youthful and second period of adulthood according to Heath–Carter.Material and methods. 167 young men and 41 men of the second period of mature age of the Yakut nationality were examined. The examination included anthropometric measurements and bioimpedance analysis of the body BMI and waist-to-hip ratio were calculated. Somatotyping according to Heath–Carter was carried out on the basis of ecto-, meso- and endomorphic scores, which are included in the bioimpedancemetry protocol. Statistical processing of the obtained data was carried out using the SPSS 17.0 application package. The normality of the distribution of parameters was determined by the Kolmogorov–Smirnov criterion. Mean (M) and standard deviation (SD) were calculated, and intergroup differences were assessed using Student's t-test.Results. The study revealed age differences in terms of length, weight and body composition. Significantly large values of body length, relative parameters of skeletal muscle mass and active cell mass were found in young men. Mature men had significantly higher body weight values, absolute and relative indicators of fat mass, absolute values of active cell mass. According to BMI, overweight was detected in 6.6%, obesity - in 3.0% of young men. Among men of mature age, overweight was determined in 54.2%, obesity - in 27.0%. A high index of the ratio of waist circumference to hip circumference was found in 4.8% of boys and 58.5% of men. The distribution of somatotypes according to Heath-Carter revealed that young men in 100% of cases had a mesectomorphic somatotype. In mature men, the mesectomorphic type was also the predominant somatotype (95.8%). In 4.2% of men of mature age, a balanced ectomorphic type was determined. The absence of variability in body types suggests that the mesectomorphic somatotype is the most adapted to living in the extreme natural and climatic conditions of Yakutia.

Published: January 2023

The Interdisciplinary Cardiac Arrest Research Review (ICARE) group was formed in 2018 to conduct an annual search of peer-reviewed literature relevant to cardiac arrest. Now in its fourth year, the goals of this review are to highlight annual updates on clinically relevant and impactful clinical and population-level studies in the interdisciplinary world of cardiac arrest research from 2021. To achieve these goals, a search of PubMed using keywords related to clinical research in cardiac arrest was conducted. Titles and abstracts were screened for relevance and sorted into seven categories: Epidemiology & Public Health; Prehospital Resuscitation; In-Hospital Resuscitation & Post-Arrest Care; Prognostication & Outcomes; Pediatrics; Interdisciplinary Guidelines; and Coronavirus disease 2019. Screened manuscripts underwent standardized scoring of methodological quality and impact by reviewer teams lead by a subject matter expert editor. Articles scoring higher than 99th percentile by category were selected for full critique. Systematic differences between editors’ and reviewers’ scores were assessed using Wilcoxon signed-rank test. A total of 4,730 articles were identified on initial search; of these, 1,677 were scored after screening for relevance and deduplication. Compared to the 2020 ICARE review, this represents a relative increase of 32% and 63%, respectively. Ultimately, 44 articles underwent full critique. The leading category was In-Hospital Resuscitation, representing 41% of fully reviewed articles, followed by Prehospital Resuscitation (20%) and Interdisciplinary Guidelines (16%). In conclusion, several clinically relevant studies in 2021 have added to the evidence base for the management of cardiac arrest patients including implementation and incorporation of resuscitation systems, technology, and quality improvement programs to improve resuscitation.
Determination of -potential of nanofluids based on electrolyte solutions from the measurements by the methods of electrical spectroscopy and laser correlation spectroscopy
Authors: Balika S.D. 
Published: January 2023

The work discusses the problem of measurement of the -potential for electrolyte-based suspensions of nanoparticle. A theory is presented for the effect of the diffuse electric double layer, including the interphase (stagnant) layer, on the effective conductivity of such suspensions. The theory is based on the method of compact groups of inhomogeneities applied to a model system of hard-core–penetrable-shell particles embedded together with the base liquid in a uniform host of the conductivity . The cores represent the particles. The shells are electrically inhomogeneous in the radial direction, their conductivity profile being a continuous function σ2(r). The overlapping components obey the rule of dominance, according to which the local conductivity value is determined by the distance from the point to the center of to the nearest particle. This model is possible to analyze rigorously in the static limit. The desired conductivity is found from the integral relation which allows us to express the electrical conductivity in the terms of the -potential, thickness of the stagnant layer, matrix molarity, etc. The theory reveals the existence of different scenarios of behavior of the conductivity depending on the geometrical and electrical parameters of the stagnant layer. It is shown that the functional dependence between the thickness and -potential can be obtained from the rate of change of the conductivity with concentration for diluted suspensions; this rate can be measured experimentally. It is pointed out that the hydrodynamic radius of a nanoparticle can be obtained from the Smoluchowski-Einstein diffusion coefficient, which can be measured by the method of laser correlation spectroscopy. We give all necessary estimates and relations to demonstrate the opportunity of measuring the -potential by analyzing together the results obtained by the indicated methods. Namely, in order to find the-potential, it is necessary to simultaneously do a series of independent measurements: find the slope of the conductivity and estimate the thickness of the stagnant layer.

Published: January 2023

The paper presents the results of an analytical study of the vapor-gas bubble dynamics in cavitation processes, giving consideration to the liquid compressibility. The study is based on the concept that cavitation effects are directly related to the occurrence of hydraulic shock on the surface of an extremely compressed bubble. The purpose of this work is to study cavitation bubble dynamics accounting for the spherical water hammer effects. An equation for the bubble dynamics was obtained, which includes the coefficient of liquid adiabatic compressibility as a basic parameter that is directly related to the liquid compressibility. For this equation reduces to the classical Rayleigh-Plesset equation for incompressible liquids. The results of a computational experiment performed within the framework of the modified model are presented for which the behavior of a cavitation bubble both in compressible and in incompressible water was analyzed. Based on a detailed analysis of the results obtained, it is shown that over time .the compressed bubble is in the state of a supercritical fluid with temperature up to 2000 K and pressure of about 400 MPa. The potential energy of the compressed liquid, in the form of a powerful acoustic pulse, emitted by the bubble at the stage of its collapse, is irreversibly dissipated in the surrounding liquid.
PRAGMATIC PECULIARITIES OF VERBALIZATION OF SECRET IN ENGLISH FICTIONAL DISCOURSE
Authors: GRIGORIAN Anna I. 
Published: January 2023

The relevance of this article is determined by the constantly growing interest that researchers take in the study of cognitive linguistics and psycholinguistics of how and why people decide to keep or, conversely, reveal secrets. The purpose of our study is to describe the verbalization of the concept secret in modern English literary fictional discourse. The communicative acts of hiding or revealing secrets in personages’ speech have been chosen as the object of our investigation. The subject of the research comprises the semantic means used by the communicators to tell his/her secret, or to conceal it. As a result of our research, we have offered a definition of the concept secret as a piece of information, kept from the knowledge of others or shared only confidentially with a few. The analysis of the reasons for keeping secrets has been helpful to identify possible circumstances that lead to secretiveness. Moreover, two types of secrets have been differentiated: one’s own secret that is face-threatening for the speaker and secret concerning a third person that can serve as a source for blackmailing. These types of secrets have been traced and analyzed in fictional discourse with the help of author's remarks, and inner speech of the personages. In the course of the analysis, a number of adjectives and intensifying adverbs that are used along with the word secret in personages’ speech have been singled out.

Authors: DEDE Yuliia V. 
Published: January 2023

The aim of the study is a contextual and interpretive analysis of mitigation strategies of request and promise which are followed up in the personage speech in English fictional discourse. The subject of the article is establishing of the speech means that implement the mitigation strategies (namely, mitigation of promise and mitigation of request), taking into account the aspect of communication situation on the samples from English fictional discourse. The findings of the research illustrate how the outlined strategies (mitigation of promise and mitigation of request) are manifested in English fictional discourse. The results show that the strategy of request is mostly realized by the tactics of categoricalness reduction. The tactics of categoricalness reduction is determined by the speaker’s desire to make interlocutor perform / not perform a certain action. The mitigation strategy of promise is realized by the apology tactics and the tactics of categoricalness reduction which allow the speaker to restore harmony with the listener.

Authors: KOSOVETS Marharyta V. 
Published: January 2023

The present article reports on the study of the communicative strategy of self-presentation and the communicative tactics that manifest it in detective discourse. The analysis is based on the data from English detective novels. The object of the study is the characters’ speech: the detective’s interrogation of witnesses and suspects. The scope of the study is the communicative tactics of self-presentation as the means of influencing the suspect in order to obtain the necessary information to solve the crime. The purpose is cognitive and pragmatic analysis of the communicative tactics applied by the detectives to obtain the necessary information to solve a crime. The investigation is based on the general and special linguistic methods : synthesis and analysis, method of observation, descriptive method, pragmatic and linguistic method, analysis of contextual interpretation. The main results of the study. The cognitive and pragmatic analysis of the detective’s strategic plan has resulted in our own classification of communicative tactics and strategies applied by the detective during the interrogation of witnesses and suspects. It has been established that one of the major communicative strategies used by the detective is self-presentation. Self-presentation is realized by the following communicative tactics: tactics of distancing, solidarity, belonging to a certain group. Each of these tactics is manifested by certain lexical, morphological and syntactic means of the English language. The perspective for further research is seen in the comprehensive study of the linguistic mechanisms of manipulative impact on the recipient in fiction.
