Published: April 2021

This study investigates the seasonal and spatial water quality patterns along a tropical river that continuously receives various pollution sources. Multivariate analysis was used to study the spatial and temporal variations of the water quality parameters and to determine the origin of the pollution sources. Three regions (low, moderate, and high pollution levels) were determined based on cluster analysis. The stepwise DA mode proposed six parameters (pH, EC, COD, NO3, TC, and Fe) with 75% correct assignations as the most significant water quality parameters to present the spatial variations. In the temporal discrimination, forward stepwise mode analysis showed eight parameters (EC, TUR, BOD,COD, AN, NO3, Cu, and Cr) with 92% correct assignations, while five parameters (EC, AN, Al, Cu, and Cr) affording 89% correct assignations in backward stepwise mode analysis. Principal component analysis and factor analysis were used to investigate the origins of each water quality parameter based on the three clustered regions and successfully yielded eight latent factors loadings for each period that significantly identified the pollution sources and types along the river. The pollution sources for moderate and high pollution level areas are anthropogenic sources (landfill, industrial activities, and sewage discharge). Agricultural runoff is the main pollution source for the low pollution level areas. This study has shown classifications of river water quality based on seasonal and spatial criteria.
A Review on Wild Indigenous Eggplant, Terung Asam Sarawak (Solanum lasiocarpum Dunal.)
Authors: ALBERT TING KOON SOON , DING PHEBE
Published: April 2021

Terung Asam Sarawak (Solanum lasiocarpum Dunal.), also known as terung Dayak or sour eggplant is one of the largest indigenous crops in Sarawak. It has slowly gained a significant commercial importance in Malaysia especially East Malaysia. There have been several studies on Terung Asam Sarawak in the last few decades but mainly focus on plant vernacular and morphology with only some studies focusing on the fruits. The agronomic practices of the plant until fruit postharvest handling have not been comprehensively studied. The information on Terung Asam Sarawak scatters in diverse sources, either local or regional sources, and in several languages too. Therefore, this review attempts to compile these all literature and outline every important finding (from plant origin to planting, fruit postharvest handling, uses and many more) about Terung Asam Sarawak in order to pinpoint the gaps of knowledge. It is hope that this review could assist researchers to focus on the gaps that will help to establish this indigenous eggplant as an important commercial vegetable in tropical countries.
Rare Earth Elements and Fractionation of Zr-Hf and Y-Ho: Implication to Petrogenesis of Idanre Granite, Nigeria
Authors: Olagoke Akinola O. , A. Ghani Azman , James Elvaene
Published: April 2021

Idanre area which is situated within the Nigerian shield is affected by orogenic activities accompanied by emplacement of Pan-African granitoids. This paper presents a new information on geochemical behaviour of Rare Earth Elements (REEs) and High Field Strength Elements (HFSEs) Zr-Hf and Y-Ho that can explain post magmatic processes relating to the origin and evolution of the Idanre granite. Zr-Hf, Hf-(Zr/Hf) and Y-Ho, (Y/Ho)-Ho variation diagrams depicted similar mobility and migration patterns for Zr, Hf, Y and Ho. Binary plots of Log Zr/Hf vs Log Hf, Log Y/Ho vs Log Ho; high LREE/HREE and negative Eu anomaly shows extensive plagioclase and calcic amphibole fractionation. High Ce/Yb values 113.49, 134.97, and 123.6 reflects low partial melting in the source rocks. Similar Zr/Hf ratios 39.16; 39.3 and 43.26 for members of the granite suite suggest a common source for the minimally differentiated magmatic fluid. Y/Ho ratios of 27.15, 27.12 and 25.91 indicate that the rock units are comagmatic. Mean Zr/Hf (41.69) and Y/Ho (27.18) ratios indicate the host migmatite may be the source rock for the Idanre granite complex.

Phenotypic associations among yield-related traits and the pattern of influence in crops are useful in evaluating, planning and selection criteria for the desirable traits. This research aimed to evaluate linear correlations and estimate the direct and indirect effects among morphological traits on oil yield of MPOB-Senegal germplasm. Data were collected annually for successive eight years (2000 to 2007) and was estimated for the phenotypic correlations, and decomposition into direct and indirect effects using path coefficient analysis. The result of the correlation and path coefficient analysis showed significant highly positive relations between some yield components and oil yield. Oil to wet mesocarp (OTWM) and bunch number (BNO) had high positive direct effect on oil yield while fresh fruit bunch (FFB), oil to fiber (OTF), fruit to bunch (FTB), and average bunch weight (ABWT) showed indirect effect on oil yield. In improvement of palm oil yield, traits that show high direct and/or indirect effect on oil yield should be considered. Hence, FFB, OTF, FTB, OTWM, and ABWT have maximum direct and indirect effect can be used effectively for the improvement of the palm oil yield of the MPOB-Senegal oil palm germplasm.

Published: April 2021

Hybrid combinations of feature selection, classification and visualisation using machine learning (ML) methods have the potential for enhanced understanding and 30-day mortality prediction of patients with cardiovascular disease using population-specific data. Identifying a feature selection method with a classifier algorithm that produces high performance in mortality studies is essential and has not been reported before. Feature selection methods such as Boruta, Random Forest (RF), Elastic Net (EN), Recursive Feature Elimination (RFE), learning vector quantization (LVQ), Genetic Algorithm (GA), Cluster Dendrogram (CD), Support Vector Machine (SVM) and Logistic Regression (LR) were combined with RF, SVM, LR, and EN classifiers for 30-day mortality prediction. ML models were constructed using 302 patients and 54 input variables from the Malaysian National Cardiovascular Disease Database. Validation of the best ML model was performed against Thrombolysis in Myocardial Infarction (TIMI) using an additional dataset of 102 patients. The Self-Organising Feature Map (SOM) was used to visualise mortality-related factors post-ACS. The performance of MLmodels using the area under the curve (AUC) ranged from 0.48 to 0.80. The best-performing model (AUC = 0.80) was a hybrid combination of the RF variable importance method, the sequential backward selection and the RF classifier using five predictors (age, triglyceride, creatinine, troponin, and total cholesterol). Comparison with TIMI using an additional dataset resulted in the best ML model outperforming the TIMI score (AUC = 0.75 vs. AUC = 0.60). The findings of this study will provide a basis for developing an online ML-based population-specific risk scoring calculator.

In recent years, Moringa oleifera has received commercial interest for its blood pressure (BP)-lowering effect. The objectives of this study were to investigate the hypotensive, diuretic, and angiotensin converting enzyme (ACE)-inhibitory activities of M. oleifera ethanolic and aqueous extracts. Spontaneously hypertensive (SH) and normotensive (NT)rats were fed the ethanolic and aqueous extracts at a dose of 1000 mg/kg each for 14 days. The rats were allocated to 12 groups of five rats each. Systolic and diastolic BP were measured, and urine was collected. All extracts, except the aqueous stem extract, significantly reduced systolic and diastolic BP in SH rats, but none of the extracts showed significant hypotensive effects on NT rats. The ethanolic leaf extract (ELE) caused significant diuresis. Moreover, most of the extracts inhibited ACE activity significantly at 40 and 80 μg/mL. ELE, aqueous leaf extract (ALE), and ethanolic pod extract (EPE) showed the highest levels of inhibition (>50%), and their IC50 values; ELE (58.65±1.55), ALE (71.35±1.00) and EPE (54.04±1.00) were determined. The hypotensive effect observed was achieved either by diuretic or ACE-inhibitory activity. The active extracts are worthy of further investigation, as they have the potential to be developed as dietary supplements for pre-hypertensive individuals.

Published: April 2021

There is an on-going debate about medicinal use of kratom plant (Mitragyna speciosa (MS)) on whether it has beneficial or adverse effects. This study aimed to examine long-term weight-reducing effects, toxicity, and dopamine pathway activation of MS alkaloid extract on adult male Wistar rats. In anorexic study, the rats were divided into 3 groups (n = 10), receiving intragastric administration once a day for 19 weeks as control (distilled water), chronic (20 mg/kg MS alkaloid extract) and withdrawal (20 mg/kg MS alkaloid extract for week 1-12 and distilled water for week 13-19) groups. Body weights were measured daily, and blood samples were collected at the end of study for biochemical and hematological tests. In immunohistochemistry, the effects of the extract (40 and 80 mg/kg) on the nucleus accumbens (NAc) and striatum (STr) were determined by using Fos-like immunoreactivity. From week 2 to 19, the results showed a significant reduction in body weight gain produced by the extract. Cessation of the treatment at week 12 did not result in a rebound weight gain. Chronic MS alkaloid extract treatment significantly decreased non-fasting blood sugar, triglyceride, uric acid and blood urea nitrogen (BUN). However, elevated SGOT may suggest possible hepatotoxicity. Chronic MSalkaloid extract treatment also produced baseline levels for most of the hematological parameters except a decrease of monocyte. In immunohistochemistry, the acute treatment did not induce Fos-like immunoreactivity in the NAc and STr.These data demonstrated the beneficial effects of the MS alkaloid extract for possible treatment of metabolic syndromes without toxicity and rewarding effect.

Authors: NORDIN ABID , SAIM AMINUDDIN BIN , HJ IDRUS RUSZYMAH BT
Published: April 2021

Neurodegenerative diseases are cluster of disorders arising from neuronal cell death in the central nervous system. Its prevalence increases with increasing age. Therapeutic options for neurodegenerative disease include protection against oxidative damage, attenuation of neuroinflammation, maintenance of essential neurotransmitters, and protection against environmental factors that induce neurotoxicity. Honey with its antioxidative, anti-inflammatory, and cytoprotective effects is a potential candidate for therapy in neurodegenerative diseases. The present evidence-based review summarizes the effects of honey on neurodegenerative diseases in non-human subjects. Three electronic databases, namely PubMed, Ovid Medline and Scopus were searched for records published from inception of database to May 2020 to identify reports on the association of honey and neurodegenerative diseases. Based on the preset eligibility criteria, 8 qualified articles were selected and discussed in this review. Honey from different geological origin around the globe was used by different researcher among the studies included. Honey confers protection against oxidative stress induced by hypoxia and metabolic syndrome, aluminium toxicity, and neuroinflammation. Honey also demonstrated potential ability to inhibit neurotransmitters degrading enzymes and restore memory impairment. This review showed a sparse body of evidence on the potential of honey as neurodegenerative disease therapy.

The consciousness of schoolchildren and giftedness
Authors: Proskurina Anna A.
Published: April 2021

The paper addresses the problem of theoretical determination of the presence and quality of the necessary and steady interrelation between the consciousness and the giftedness of schoolchildren. It is argued for the need of a social philosophic approach to the solution of this problem in the perspective of subjective action. The problem is tackled by means of the theoretical analysis of speech functions in the performance of subjective action by a social individual. The study reveals, on the one hand, which subjective action elements the acting individual is necessarily aware of. On the other hand, it is shown which elements of self-concept, when purposefully and artificially developed, are an obstacle for the performance of subjective action
Attracting children’s attention to literature through the object of project activity-table theater

Published: April 2021

Today, there are many electronic devices that can replace the things we are used to. Todays children and adolescents spend more and more time learning new means of communication and searching for information, which is why traditional means (books, communication, experience) take a back seat and eventually become less important for overall development. While studying in primary school, it is easier for children to work with Internet sources because of the simplicity and conciseness of information that is in General use. Reading material from a book is replaced by gadgets. The very concept of reading has acquired a different meaning, has ceased to be a part of culture. Many parents and teachers face this problem when trying to teach their children to read literature. The purpose of this project is to find an alternative way to attract children to literary works through the object of project activity-table theater for children.

El rol de la Hidrología Subterránea para el logro de la Seguridad Hídrica
Authors: Paris Marta , Pérez Marcela , D'Elía Mónica
Published: April 2021

El concepto de seguridad hídrica focaliza el objetivo de la gestión del agua en la sociedad.  Sin embargo, en los ambientes urbanos -donde deben atenderse requerimientos relacionados al abastecimiento de agua, inundaciones, lluvias intensas, ascenso del nivel freático, problemas de contaminación, entre otros-, la falta de datos e información adecuadas a la escala de trabajo, e incluso el uso inapropiado de metodologías, atentan contra cualquier intento de mejorar esta capacidad de la población para hacer frente a las situaciones críticas.  Incluso en las ciudades es más evidente que el desafío de lograr el equilibrio entre la oferta de agua –finita, vulnerable y variable-, y una oferta -incansablemente creciente, de múltiples usuarios e interdependiente-, obliga a “re pensar” el ciclo hidrológico como un sistema ambiental dinámico y con ello, a sumar a la Hidrología un enfoque interdisciplinar. En este trabajo se presentan las metodologías, resultados y conclusiones que han servido de base para mejorar el conocimiento de los sistemas acuíferos de las ciudades de Esperanza y Santa Fe (Argentina).  La primera sustenta su abastecimiento con aguas subterráneas, con lo cual es indispensable la protección del recurso y las obras de captación.  En el segundo caso, la interrelación entre el agua superficial y la subterránea es compleja y requiere que hidrodinámica del sistema en su conjunto deba ser considerada para definir las mejores alternativas tecnológicas de la infraestructura urbana y el manejo de las inundaciones. Los avances logrados señalan la importancia de la ciencia, como motor que genera soluciones efectivas para que la sociedad alcance las metas del desarrollo sostenible y la seguridad hídrica.
Reevaluación del potencial geotérmico de los granitos de Galicia en base a cartografía geoquímica y radiológica
Authors: Sanjurjo-Sánchez Jorge , Barrientos Rodríguez Victor
Published: April 2021

El flujo de calor en la corteza superior determina la posibilidad de utilizar la energía geotérmica en una determinada zona. Este flujo es muy heterogéneo por lo que el aprovechamiento de la energía geotérmica es muy variable y requiere un estudio de cada zona. Donde no existen condicionantes geológicos que produzcan un flujo de calor anómalo y elevado, el aprovechamiento de esta energía es más limitado, dependiendo de las propiedades de las rocas del substrato, pero aun así enormemente variable. Los estudios realizados en Galicia hasta la fecha indican que el aprovechamiento geotérmico en esta comunidad es limitado debido a la ausencia de anomalías y a la litología, existiendo un potencial geotérmico bajo. Sin embargo, los principales estudios orientados a este fin, aun considerando información geológica, han sido genéricos, imprecisos y conservadores. La existencia de nuevos datos geoquímicos y de radiación gamma permite una reevaluación de estos estudios. Esta reevaluación muestra un potencial mayor del estimado inicialmente, lo que sugiere la necesidad de realizar estudios más detallados de la geoquímica de las rocas para obtener una evaluación más precisa y exacta, algo necesario para un desarrollo adecuado del aprovechamiento de esta energía en la comunidad.
Horace R. Blank and the origin of rock doughnuts
Authors: Twidale Charles Rowland
Published: April 2021

Rock doughnuts are annular rims developed around rock basins that intermittently carry pools of water. They are developed in granitic rocks, and in arenaceous and calcareous sediments and in coastal as well as interior settings. Rock levees are found adjacent to gutters but are of a similar nature and origin.  Both doughnuts and levees can be attributed to the development of protective coatings or veneers by biota, and of silica, iron oxides, and carbonates by overflowing pool waters. Contrasts in drainage from regolithic covers, weathering at sheltered interfaces and variations in runoff can also be cited at causative factors and situations.
Nota sobre la última transgresión marina en la costa de Galicia
Authors: Grandal d’Anglade Aurora , Vidal Romani Juan Ramón
Published: April 2021

Desde el final del Pleistoceno hace 12.700 años hasta el día de hoy se están produciendo efectos dramáticos en toda la orla litoral de la costa de Galicia debidos esencialmente al ascenso del nivel del mar en toda la costa con una velocidad media entre 3mm y 3,5 mm anuales desde el inicio del Holoceno  y que se evalúa, aproximadamente, en unos 40,95 metros. El efecto inmediato ha sido una progresiva reducción de la anchura de una plataforma continental cubierta por playas y extensos campos dunares lo que produjo una migración hacia el continente de los depósitos arenosos movilizados por las olas (playas) y/o por el viento (dunas). En el momento actual se ha alcanzado prácticamente el límite del avance transgresivo holoceno al situarse el mar en la base de la costa rocosa acantilada o en su caso frente a alguna masa de agua dulce (ríos o lagunas costeras) que frena temporalmente el avance de las dunas o la acumulación de arenas de playa. La acción marina está procediendo a la destrucción acelerada de las playas donde el viento primero excava sus corredores de tormenta que luego el mar, durante los temporales, utilizará para invadir el interior del continente. En las zonas de costa rocosa la acumulación de la arena produce las características dunas rampantes o trepadoras. En este trabajo se aportan algunos datos de gran interés referidos a la exhumación de los niveles de antiguos bosques y su fauna asociada, presentes desde el inicio del Holoceno en la franja litoral, y que ahora, efímeramente, vuelven a ser puestos al descubierto antes de ser destruidos definitivamente por la acción de las olas.

Ao comparar os grupos observou-se que não houve diferença entre eles. Os tratamentos propostos foram capazes de proporcionar o aumento da ADM de punho da população estudada, não havendo diferença entre os grupos.
Effect of Violence against Women on Victims and their Children: Evidence from Central America, the Dominican Republic, and Haiti
Authors: Anglade Boaz , Escobar Julia
Published: April 2021

This paper presents a systematic overview of the evidence of violence against women in the Central America, Mexico, Panama, Haiti, and Dominican Republic region and examines its impact on the well-being of women and their children. Population-based surveys show that violence against women remains a widespread issue in the region. The proportion of women who have experienced physical or sexual violence at least once in their lifetime varies between 13% and 53%; Panama has the lowest rate while Mexico and El Salvador have the highest. The percentage of women who have experienced violence within private spheres ranges between 17% and 24%. Also, homicidal violence targeting women remains a major problem in the region. Using a novel propensity score reweighting technique, we assess the impact of violence on a series of outcome variables related to a womans health and socioeconomic condition. We find evidence that violence against women negatively affects victims reproductive and physical health as well as their fertility preferences. We also find evidence that violence against mothers has an adverse effect on childrens advancement in school and overall health.

WorkerTech se define como los servicios digitales que ofrecen a los trabajadores independientes beneficios para mejorar las protecciones sociales y la productividad. Hoy en día, pensar solo en términos de trabajo asalariado a tiempo completo y contrato indefinido, ignora a los millones de personas que agregan fuentes de ingresos y dan forma a sus vidas mediante una amplia variedad de relaciones laborales no convencionales, que se vienen consolidando en el siglo XXI. El paso del trabajo asalariado tradicional a nuevas modalidades implica que las personas trabajadoras deben reconstruir la estructura laboral necesaria para poder trabajar. Aquí es donde entran los servicios WorkerTech. El concepto que nació en Europa es relevante para América Latina y el Caribe, sobre todo cuando la región está sufriendo mucho el tema de desempleo por la pandemia. El concepto se aplicará también a los trabajadores del sector informal que comparten mucho desafíos de los trabajadores independientes de modalidades modernas.
Creativity, Sociability, Solidarity: New-Wave Carnival Krewes’ Responses to COVID-19 in New Orleans
Authors: Radice Martha
Published: April 2021

New Orleans was one of the first cities in the USA to be severely affected by the COVID‑19 pandemic. This article draws on long-term ethnography and recent remote fieldwork to explore how new-wave carnival krewes in New Orleans responded to the pandemic. New-wave krewes are one of the kinds of social clubs that produce carnival each year. During the first four months of the pandemic, some of them undertook various kinds of projects within their membership and in the broader community. I propose that these projects have three overlapping dimensions: creativity, sociability, and solidarity. My argument is that because they are so enmeshed in the social fabric of New Orleans, new-wave carnival krewes provided a solid foundation for social initiatives that sought to alleviate the existential and material insecurity of the pandemic. I further argue that carnival has emerged as an important way for New Orleanians to make the imaginative connection between the personal and the social that is necessary for grasping the scope of COVID‑19. More broadly, I contribute to what Joel Robbins has called an “anthropology of the good” in social relations.
A Study on the Socio-Demographic Profiles of Road Traffic Accident Cases Attending a Peripheral Tertiary Care Medical College Hospital of West Bengal
Authors: Dutta Sirshak , Sarkar Debasis , Mallick Nazrul
Published: April 2021

BACKGROUND A road traffic accident (RTA) is any injury due to crashes originating from, terminating with or involving a vehicle partially or fully on a public road. Increased mechanisation and improved socio-economic condition of the people in developing countries like India leads to increased use of motor vehicles, disproportionate to the increase in the number of roads. We wanted to assess the socio-demographic profile of road traffic accident victims and study the antecedent factors influencing the road traffic accidents. METHODS This is an institution based descriptive, cross-sectional study, conducted among 114 patients. RESULTS Maximum numbers of the victims, 33.32 % (N = 38) were in the age group of 21-30 years followed by 26.31 % (N =30) in the age group of up to 20 years, mean age of the victims was 29.53 ± 13.85. Majority of the victims, 70.05 % (N = 80) were on motorcycles, and 26.32 % (N =30) of the victims were alcoholic at the time of accident. Majority of the victims, 92.86 % (78 out of 84), among the motor-cycle riders, four-wheeler drivers, and front seat passengers had not used any safety measures at the time of accident. CONCLUSIONS Road traffic accidents emerged as the major epidemic of non-communicable disease, holding a major share of mortality and morbidity data all over the world, majorly among the young productive portion of the population. It was evident from the study that the majority of victims were young adults, from lower socioeconomic background, and rural residents. So, lack of proper information and consciousness regarding road safety rules and measures are definitely the important aetiology behind this epidemic. Almost two third of the cases were among the bikers in the present study, which is pointing out the need of focusing on the road safety rules related to bikers by the road traffic authority.

Artistic Polemic with A.P. Chekhov in the Story by T.L. Shchepkina-Kupernik “Loneliness”
Authors: Kubasov Alexander V.
Published: April 2021

From the earliest works, Chekhov acts as a polemicist with both contemporary literature and with the literature of the immediate past. This polemic is expressed not so much in the direct statements of the writer in letters or in conversations recorded by the memory of the memoirists, but in an artistic form, with the help of an imaginative system. However, there were people who polemicized with Chekhov. On the one hand, these were magazine critics, and on the other, fellow writers. One of these authors was T.L. Shchepkina-Kupernik, who wrote the story "Loneliness" at the age of twenty, which was published in the authoritative journal “Russian Thought” in 1894. The works of Chekhov, which caused the greatest resonance among the reading public: “The Jumping Girl”, “Boring Story”, “Ward No. 6”, became the material for the polemic of the young writer. Shchepkina-Kupernik actually agrees with the opinion of the readers who recognized the element of libel in the story "The Jumping girl", and the element of distortions of reality in others. The author of “Loneliness” creates an artistic picture of the world, which seems to her more realistic than Chekhov’s. However, the story of the young writer does not go beyond the bounds of stencil mass literature. All her claims against the author of “Ward No. 6” turn out to be untenable and demonstrate her lack of understanding of the innovative nature of Chekhov’s work. The complex nature of the dialogic character of his works, based on the art of parody stylization, was not perceived by the opponent, who opposed it with a one-dimensional and simplified image of reality.

The title of the collection and the epigraph “The Great Feast of the First Meetings”, preceding the cycle, is a line from the poem “At Noon” from the cycle “From Hell Expelled” “Wreath”, the intertextual correspondent of structure and composition is the poetry collection “Urbi et Orbi”. Here we can talk about the creative interpretation of symbolism, and the last cycles of the collection Ynterieurs and The Enchanted Castle, written after they met in 1908, bear the direct influence of the poetry of Z. Gippius.
Pragmatics of Advertising Text in the Aspect of its Suggestive Impact
Authors: Kalinovskaya Elena A. , Kobysheva Anna S.
Published: April 2021

The article defines and describes the main ways of suggestive impact in advertising texts. The language-specific nature of advertising texts is often reduced, as the marketing aspect is highlighted. One of the main functions of the advertising text is the suggestive function, since this type of texts is designed to impact a person emotionally, psychologically, and manipulatively. Despite a number of works devoted to linguistic suggestion in advertising, this aspect remains poorly studied, due to the constant expansion of the range of manipulative strategies used in advertising texts. The empirical material for the present study, i.e. advertising texts, was collected from English versions of ELLE, OUT, WOMEN’S HEALTH magazines. An advertising text is a complex semiotic unity with the following properties: polysemioticity (elements of various sign systems are used to construct such a text), imperativeness (an advertising text is designed to induce an addressee to act), and suggestiveness (texts of this type are saturated with persuasion techniques). Verbal and non-verbal levels of manipulative techniques are distinguished. They are background and color as main medium of conceptual information, re-accentuation, graphic techniques, words and phrases with positive semantics, imperative, lexical-stylistic and grammar-stylistic devices.
Classification Thematic Groups of English Borrowings of the Semantic Field “Beauty” Based on the Material of Russian Glossy Female Magazines

Published: April 2021

An enormous flow of foreign lexical units into the Russian language is caused by a number of extra-linguistic and intra-linguistic reasons. The whole experience of foreign advertising is borrowed and in particular the technique of creation of advertising messages, which has led to the use of English borrowings in Russian. The purpose of the article is to describe and classify thematic groups of English borrowings of the semantic field “beauty”, based on the material of Russian glossy female magazines. Classification thematic groups of English borrowings of the semantic field “beauty” in Russian glossy female magazines are widely spread and relevant, which devoted to beauty, care, makeup types and vocabulary related to the beauty industry. English borrowings presented in these groups are the most common and well-known, since the beauty industry occupies a significant place in the world. Editors of glossy magazines, authors of articles and advertising messages resort to using a huge number of Anglicisms in order to interest the reader with novelty, expression, thereby increasing the sales of magazines and accordingly advertised goods, the demand for appropriate services in the beauty industry. Such a universal interest in beauty in all its manifestations predetermined the folding of the metalanguage as a system of signs and certain discursive resources. A relevant feature of the modern Russian language and metalanguage of the beauty industry is the use of English borrowings, which are typical of this sphere, in all studied glossy publications. Based on the list of given examples and classification, we can confidently say that English borrowings are firmly entered in the living space of the advertising text. The reasons for the extralinguistic and intra-linguistic nature played a significant role in expanding the lexical-semantic system of the Russian language.
Implementation of Ethnic Identity in the Media Discourse
Authors: Kopot Liliya V.
Published: April 2021

The article aims to describe the specifics of the verbal implementation of ethnic identity in the Russian media discourse. The relevance of the work is due to the anthropocentric approach to linguistics, based on interdisciplinary connections with philosophy, cultural studies, literary studies, anthropology, etc., which significantly enriches the linguistic study of identity in the media discourse. The novelty of the research lies in the fact that the question of understanding media discourse as a verbal and informational continuum, in the space of which specific units are functioning, containing ethnocultural meanings and participating in the formation of the ethnic identity of a particular community. The significance for the theory of language is determined by the fact that extended and justified interpretations of the concepts “ethnicity” and “ethnic identity” are presented. The main parameters of the implementation of ethnic identity in the media discourse are established. The main lexical and semantic means that construct selfidentification in the modern media discourse were analyzed. And also, the accompanying markers of mass information discourse are highlighted. Within the framework of the structural-semantic approach, the following methods were used: discourse analysis, contextual, definitional, and continuous sampling. The results obtained can be used in a course of lectures on ethnolinguistics, sociolinguistics, and linguoculturology.
Peripheral Means of Expressing the Meaning of Animate – Inanimate
Authors: Bak Hadi
Published: April 2021

The study of the meaning of animate-inanimate cannot be limited to the consideration of isolated nouns, since the word always functions as part of a certain construction, as part of a certain context. The article deals with the manifestation of the meaning of animateness-inanimation in the semantics of pronouns, verbs, adjectives and adverbs.

Currently, practically the entire volume of water extracted in the process of hydrocarbon exploitation is utilized by injection into deposits. Changes in the physico-chemical parameters (pH, red-ox potential, temperature, etc.) of the water during extraction and the contact of the injected water with the native water and deposit rock may result in the precipitation of sediment particles and suspensions. It causes clogging of the near-wellbore zone and limits the amount of water that can be injected with the injection well. Due to the high complexity of the system: the injected water–reservoir rock, and a wide range of interactions between individual components, the analytical data does not always allow for the correct interpretation of the course of the processes and determination of their impact on the permeability of the near-well zone. Using the results of physico-chemical analyses of the composition of separator water samples with different properties – two samples with low mineralization S1K (575 mg/dm3) and S4K (551 mg/dm3), a sample with high S2K (306 428 mg/dm3) and medium mineralization S3K (79 858 mg/dm3) – calculations were performed using the PHREEQC program for the three databases: phreeqc.dat, wateq4f.dat and pitzer.dat. It was found that in the case of low mineralization waters, the results obtained in each of the databases are similar for the minerals present in all the databases. However, in the case of solutions with high mineralization, there are significant differences in the obtained results. The calculated solubility indices allowed to determine the direction of the precipitation/dissolution reaction of individual minerals in the deposit and to indicate the risks, mainly with the formation of iron compounds deposits, for the operation of the injection well. Laboratory tests of water mixing were also carried out. The formation of iron oxide deposits that could damage the near-well zone was observed, which confirmed the results obtained during computer simulations.
