Authors: PERMANA MOCH ARIL INDRA
Published: August 2023

Silica scaling merupakan masalah yang sering ditemukan pada pembangkit listrik geothermal terutama yang memanfaatkan fluida water dominated (brine). Silica scaling dapat terbentuk akibat adanya flashing yang menyebabkan penurunan tekanan, temperatur dan kenaikan pH sehingga kelarutan brine menjadi berubah. Silica scaling pada pipa produksi dapat menyumbat laju aliran fluida dan bahkan harus diganti. Dalam penelitian ini telah dilakukan kajian mengenai potensi silica scaling di pembangkit listrik tenaga geothermal di daerah Sumatera. Kajian dilakukan dengan melihat pengaruh perubahan temperatur, pH, dan salinitas ketika terjadi flashing terhadap potensi terbentuknya silica scaling dengan menggunakan silica saturation index (SSI). Hasil analisis dan perhitungan menunjukkan bahwa penurunan temperatur dan peningkatan pH akibat flashing, dan besar salinitas brine dapat meningkatkan potensi terbentuknya silica scaling pada pipa produksi dan keadaan asam merupakan kondisi terbaik untuk mencegah terbentuknya silica scaling.

Using a Novel Heterojunction CoWO4/g-C3N4 as Visible Light Photocatalyst for Photodegradation of Organic Pollutant
Authors: Van Dang Do , Linh Tran Thi Chi , Son Le Thanh
Published: August 2023

Methylene Blue (MB) is a common dye that has various applications in different fields, including medicine, biology, and environmental science. While it can be beneficial in certain contexts, it can also have negative effects on the environment under certain circumstances. In this study, the photodegradation of MB under visible light irradiation using a novel heterojunction CoWO4/g-C3N4 catalyst was investigated. A series of CoWO4/g-C3N4 composites were synthesized and characterized using various techniques, including XRD, SEM, SEM-EDS, FT-IR, and UV–DRS. The results revealed that the 0.3CoWO4/g-C3N4 composite showed the highest efficiency (93%) in degrading MB during the 80-minute photodegradation process, aligning with the pseudo-first-order kinetics. The results provide clear evidence that the formation of CoWO4/g-C3N4 heterojunction greatly enhances the efficiency of photocatalysis by facilitating the swift separation of electron-hole pairs and boosting the redox capability. Additionally, the photodegradation efficiency remained above 90% even after four cycles, suggesting the stability of the catalyst.
Noziedzīgi iegūtu līdzekļu legalizācijas novēršanas un apkarošanas krimināltiesiskā un procesuālā problemātika un pilnveidošanas perspektīvas. Promocijas darba kopsavilkums

Noziedzīgi iegūtas mantas konfiskācijas leģitīmo mērķi var definēt kā noziedzīgā veidā iegūta īpašuma izņemšanu no legālās civiltiesiskās apgrozības, lai nepieļautu tā turpmāku apriti un tālāku noziedzīgu nodarījumu izdarīšanu, kā arī – lai mazinātu finansiālo ieinteresētību veikt noziedzīgos nodarījumus. Tiesu prakses un jaunāko tendenču izpētes laikā autore ir secinājusi, ka, lai atzītu mantu par noziedzīgi iegūtu, ir nepieciešamas izmaiņas šā brīža normatīvajā regulējumā, kā arī nepieciešams laiks un izpratne attiecīgo normu atbilstošā piemērošanā praksē. Darbā tiek aplūkotas aktuālās problēmas un tendences noziedzīgi iegūtu līdzekļu legalizācijas lietās. Lemjot jautājumu par mantas legālo izcelsmi, bieži rodas gadījumi, kad iesniegtie pierādījumi no procesa virzītāju puses tiek vērtēti subjektīvi, faktiski iztrūkstot pierādījumu bāzei par līdzekļu noziedzīgo izcelsmi. Latvijas tiesiskajā sistēmā jebkurā noziedzīgā nodarījumā, kura rezultātā tiek iegūti noziedzīgi līdzekļi, jeb predikatīvajos noziegumos ir paredzēta mantas vai naudas konfiskācija, ja ir pietiekams pamats aizdomām, ka šī manta iegūta noziedzīga nodarījuma rezultātā, tas ir, bez notiesājoša sprieduma, tādējādi deduktīvi meklējot noziedzīgā nodarījuma subjektu un faktiski apejot Kriminālprocesa likuma mērķi, kas paredz tādu kriminālprocesa kārtību, kas nodrošina efektīvu Krimināllikuma normu piemērošanu un krimināltiesisko attiecību taisnīgu noregulējumu bez neattaisnotas iejaukšanās personas dzīvē, jo, kā pierāda prakse – faktiskā kārtība nenodrošina efektīvu mehānismu, bet nepamatoti pārkāpj personas tiesības. Promocijas darba temats “Noziedzīgi iegūtu līdzekļu legalizācijas novēršanas un apkarošanas krimināltiesiskā un procesuālā problemātika un pilnveidošanas perspektīvas” izvēlēts, vadoties no tā, ka ikdienas darbā un mācību procesā nereti nākas sastapties ar gadījumiem, kad lietās tiek konfiscēta manta vai kāda cita materiālā vērtība tikai tāpēc, ka nav izpratnes, atbilstošas izglītības, zināšanu vai praktiskās pieredzes, kas noved pie nepamatotiem un subjektīviem nolēmumiem, tādējādi atzīstot mantu par noziedzīgi iegūtu un konfiscējot to valsts labā. Ar šādām darbībām tiek radīts risks arī pašai valstij, jo bieži vien pret valsti tiek celtas dažāda veida prasības, tai skaitā par zaudējumu atlīdzināšanu saistībā ar Eiropas Cilvēktiesību tiesas konstatētajiem cilvēktiesību pārkāpumiem, kas jau ir signāls Latvijas likumdevējam par nepieciešamību veidot efektīvāku noziedzīgi iegūtu līdzekļu konfiscēšanas mehānismu.

GERMAN ECONOMIC TERMINOLOGY: STRUCTURAL-SEMANTIC FEATURES
Authors: Kuziv Mariia , Panychock Tetiana
Published: August 2023

In the modern world, with the deepening of the internationalization of the economy and the growing interaction between different countries, there is a need for effective use of language tools to ensure quality and accurate translation of economic terminology. German language is particularly important in this regard, as it is one of the key languages of the European Union and has great significance in the field of economics. This article discusses the structural and semantic peculiarities of German economic terms and terminological phrases; it also characterizes word formation tools and their role in defining the meanings of economic vocabulary and facilitating its translation into the Ukrainian language. The structural and semantic peculiarities of German economic terms and terminological phrases are quite complex and require careful study. German economic terminology is provided with various terms used in the fields of banking, accounting, finance, insurance, taxation, and other areas of the economy. The peculiarity of German economic terminology lies in its structural and semantic characteristics, which include both lexical and morphological peculiarities. Terminological phrases have a stable character in terms of their semantic specification. One of the ways to determine the meaning of an economic term is to use knowledge of methods and means of word formation. The peculiarity of the German language lies in its large number of word formation tools, such as suffixes, prefixes, infixes, suffixal abbreviations, and others. The use of these tools allows for the creation of new terms and terminological phrases that reflect new realities in the economy. This article is useful for those interested in linguistics, especially in the field of economic vocabulary. It can also be helpful for translators and those involved in translating texts from German to Ukrainian.
VERBALIZATION OF V. SOSIURA’S VIEWS IN THE ONYMICON OF POETIC WORKS
Authors: Lobachova Iryna , Pomyrcha Svitlana , Khvashchevska Olha
Published: August 2023

The article identifies the problem of verbalization of V. Sosiura’s views in the onymic of poetic works. It is emphasized that it’s expedient to study the idiostyles of writers whose work is symbolic both for a certain people and for the aesthetic context in general. It is noted that the processes consisting in the semantic transformation of a word, the formation of its artistic meaning, and the transformation of a word into an aesthetic sign deserve special attention in the analysis of individual features of poetic texts. The question of studying the individual stylistic features of V. Sosiura’s poetry in the semantic-functional aspect, the need to rethink and analyze his creative output from a new point, taking into account the mechanisms of word transformation in poetic texts, becomes relevant. It is determined that V. Sosiura played a significant role in the depiction of the era through the onymicon, although today we state ambiguous views on his personality, and sometimes on his creative output. In the minds of the Ukrainian people, V. Sosiura is a vivid representative of the new generation of lyric poets, who were doomed to adapt to the conditions of the ideological leadership of literature, trying to preserve the best folk song traditions. The analysis of the texts of the poems showed that among the categories of the toponymicon of V. Sosiura’s poetic picture of the world, the most numerous are the groups of choronyms, hydronyms, and oikonyms, in particular, astonyms (names of cities), hodonyms (names of streets), and urbanonyms (names of inner-city objects), to a lesser extent oronyms and dryonyms are presented, and the most diverse are oikonyms and urbanonyms, which presents the open poetic space of the author’s picture of the world.
RHETORIC OF THE FEDERAL PRESIDENT OF GERMANY IN THE CONTEXT OF THE RUSSIAN-UKRAINIAN WAR: STYLISTIC AND TRANSLATION ASPECT
Authors: Pavlyk Volodymyr
Published: August 2023

The article describes extralingual factors, functionally-communicative features, stylistic means and ways of their translation in the historic keynote speech of the Federal President Frank-Walter Steinmeier “Strengthening everything that connects us”, delivered by him on October 28, 2022. Information policy concerns all public spheres. It preconditions functioning of the social system. Change of ideas makes provision for a change in political public rhetorics as culturally accepted logic of progression of events. Rhetorics unite people emotionally, creating their identity. Texts carrying the main rhetorics in the course of the war can be called ones of the main constituents of the process of strategic communications. Texts of political speeches of the politicians during the Russian-Ukrainian war are basic factors of creation of rhetorics of this war within the societies addressed by them. The basis of their impact on the audience is the complex of stylistic tonality creation. Stylistic tonality is the text category which embodies the concentration of expressive means used by the author in their speech activity with the purpose of representation of the essence of the subject matter and their personal attitude to it. The stylistic tonality of a text is created based on the functionally-communicative features – invariant features of the texts which are based on its extralingual constituents and are called for simplification of their reveal in the text, which is the task of the addresser. They serve as mediators between the extralinguistics of the text and its linguistic implementation. The main functionally-communicative features of the speech by the Federal President are “evaluativity” and “inventivity”. Stylistic tonality of the text is characterized by the usage of metaphors, epithets, antitheses and an anaphor, as a kind of distant repetition. The most effective translation transformations of Ukrainian translation of the analysed political speech are in-context substitution, word-for-word translation, selection of variant equivalent, substantiation, omission, substitution of one part of speech with a word of another part of speech.
THE ROLE OF THE ENGLISH LANGUAGE IN THE MODERN DIALOGUE OF CULTURES IN THE ASPECT OF GLOBALIZATION
Authors: Karachova Daria , Ahibalova Tetiana
Published: August 2023

The article deals with the current topic of research on the role of the English language in modern intercultural communication, and the dialogue of cultures under the influence of the latest globalization processes. The purpose of this investigation was to identify and investigate the main factors that influence the transformation of the modern English language and their general features that change the process of modern dialogue of cultures. In the course of our research, it was found that the main factors are ecolinguistic, gender-neutral language and slangisms, which significantly affect the development and transformation of the English language, and they have influence on the features of the modern dialogue of cultures. They are the most important elements of the influence of globalization processes on the modern English language. Under the pressure of these processes, the English language, first of all, undergoes significant lexical transformations, because interaction with different cultures has made a significant impact on its lexical system. It was significantly enriched by various borrowings and graphic transformations of words – a modern type of abbreviation, which is often used in Internet communication, when words can be shortened to write only consonant letters. Also, the grammatical structure of the language is changing gradually. Every year, transformations change the English language more and more. On the one hand, the English language is greatly simplified in use, and on the other hand, the process of understanding it and transmitting the message is significantly complicated by the modern social features, such as gender-neutral language, slangisms, etc. The modern world tends to save people’s time, so the author of the message should express his or her thoughts as clearly and concisely as possible, so that the recipient should be able to quickly analyze the received information, understand it and convey it as short as possible in a foreign language. At the same time, take into account the cultural characteristics of the author of the message to avoid discrimination and conflict situations. Therefore, it is important to consider all these elements in the process of a dialogue of cultures.

Published: August 2023

Authentic poetic text as an object of foreign linguistic didactics is investigated in the article. Formation of linguo-socio-cultural competence as a constituent part of communicative competence of a philology student from the point of view of culture text study is analyzed. Attention is focused on the fact that “informative condensation” and “hyper-semanticism” as well as conceptuality, emotionality, imagery, rhythm and euphony cause inexhaustible esthetic, cognitive, communicative, personally-valuable, mnemonic, educational and training opportunities of authentic poetic text. The main object of poetry – depiction of a person; his inner world, his thoughts about the surrounding world and life in it, his attitude to other people, the nature and society; emotions, feelings and unrest of human’s soul. Depicting events and phenomena of everyday life of a person, raising his psychological, ethical, esthetical, ideological, philosophical, spiritual and other issues, expressing attitude to them of a poet as a thinker and humanist, poetry in such a way, firstly, demonstrates solution of these issues, and secondly, performs its cognitive-informational function. Is serves to enrich socio-cultural experience of a person, his spiritual, moral and intellectual improvement. Communicative, axiological, cognitive, informational, culture-bearing, meaningful functions of poetic text are characterized. Efficiency of application of foreign literature and poetry masterpieces while forming foreign communicative competence in philology students at the advanced level of study is proved.
APPLICATION OF SEMANTIC MODELS IN LITERARY STUDIES AND EXPERTISE OF COPYRIGHT OBJECTS
Authors: Kalinichenko Mykhaylo
Published: August 2023

The article examines the application of semantic models in the fields of copyright expertise and literary analysis. The content showcases various types of semantic models utilized for text analysis, such as Latent Semantic Analysis (LSA), topic modeling, named entity recognition (NER), sentiment analysis, and dependency parsing. While each model has its own advantages and drawbacks, challenges in their utilization exist, such as over-reliance on quantitative analysis, model biases, lack of contextual information, and potential misinterpretation of meaning. Nevertheless, semantic models have significantly impacted the field by enabling the identification of instances of plagiarism and copyright infringement more efficiently and accurately. The overview presented in the publication on the essence and peculiarities of using semantic models in copyright expertise and literary analysis allows for the following conclusions. Semantic models significantly improve the efficiency of text analysis. These models use advanced technologies to identify structural patterns, themes, and similar elements in texts, as well as allowing experts to gain a deeper understanding of the works they are analyzing. In the field of copyright expertise, semantic models are used for analyzing significant volumes of text and identifying possible copyright infringements. Although semantic models have many advantages, they also have functional limitations. It is important to be aware of these limitations and use analytical models in combination with other methods to ensure a more comprehensive understanding of the text. There are several ways to address possible problems with using semantic models, including combining quantitative and qualitative analysis, using multiple models at once, taking into account selection biases of analytical information, studying the broader context, and additional verification of results by human experts. Ultimately, the use of semantic models in copyright expertise and literary analysis has enormous practical value, but it is important to be aware of their limitations and use them in conjunction with other analysis methods to ensure the most objective and comprehensive research. As technology develops, new and more advanced semantic models will be developed that will allow for even more detailed analysis of texts.
THEORETICAL AND METHODOLOGICAL FOUNDATIONS OF ECOLINGUISTICS AS A NEW INTERDISCIPLINARY RESEARCH AREA
Authors: Kramar Natalie , Levko Oleksandr
Published: August 2023

The article deals with the theoretical and methodological foundations of ecolinguistics as a field that explores the relationship between language and the environment in its various manifestations. We trace the origins of ecolinguistics and its gradual transition from the study of ecological discourse as such to the analysis of ecology representations in other discourses. It is argued that ecolinguistics should be distinguished from ecology of language, since the latter is focused on interlingual relations and applies a quite different methodology. We also outline the principle of ecosophy, which underlies the methodology of ecolinguistic research, as well as the types of lexical and grammatical features representing key ideologies that influence the public perception of the environment and environmental measures. Furthermore, we explicate the ecolinguistic classification of discourses into destructive, ambivalent and beneficial for the environment, with the consideration of methodological variations corresponding to each: in particular, the use of critical discourse analysis for destructive discourses and positive discourse analysis for beneficial discourses. Attention is paid to multimodal discourse analysis as one of the complementary methods of ecolinguistics, as well as to corpus-based methods that allow for a more accurate and complete elucidation of environmental narratives of certain social groups in a synchronic or diachronic perspective. The possibility of implementing ecolinguistic principles in pedagogical practice, especially in language training, is highlighted. We conclude with the promising directions of ecolinguistic research in the modern context of Ukraine, where ecological awareness is at an extremely low level and hence the ecolinguistic vector of research seems to be highly relevant.
LINGUISTIC FEATURES OF INTERNET-DISCOURSE
Authors: Riba-Hrynyshyn Oksana , Kotous Yulia
Published: August 2023

The thesis is devoted to the study of the linguistic features of Internet discourse at the lexical, graphic, and grammatical levels. The changes that caused the active spread of social networks and websites in English are analyzed in detail. A well-grounded analysis of lexical-semantic and graphic means of online communication made it possible to understand the trends of popular social networks in more detail. The English language has been directly and powerfully influenced by online communication. Social consolidation factors have determined the main influence of the English language on the Internet in general. Being the territorial native language of the founders of famous websites and social networks, it is used most actively. English-speaking users were among the first to have access to virtual communication and laid the foundation for the creation, development and spread of the Internet language. This explains the special attention of linguists to English-language platforms. The general features of the Internet English language, which is characterized by changes at the lexical, grammatical or graphic levels, have been studied. The conducted linguistic analysis of posts on popular social networks revealed the following patterns of English-language Internet discourse, namely: 1) the use of a large number of neologisms (formed by affixation and word formation); 2) frequent use of acronyms and abbreviations; 3) pseudonyms (or nicknames) are an important feature of communication on the Internet or chat; 4) special cases of using punctuation marks, lowercase and uppercase letters, emoticons (smilies) and non-alphabetic graphic signs; 5) capitalization, hyphenation, various types of memes and gifs were detected; creolized memes are the most common; 6) at the grammatical level, frequent omission of punctuation and violation of grammatical norms of the English language. Interaction on the Internet often replaces real communication needs. Internet English reflects the general tendency to economize language and illustrates the creativity and originality of Internet users.
Chemical Kinetics in Microdroplets
Authors: Wilson Kevin , Prophet Alexander
Published: August 2023

Micron-sized compartments play significant roles in driving heterogeneous transformations within atmospheric and biochemical systems as well as providing vehicles for drug delivery and novel reaction environments for the synthesis of industrial chemicals. Many reports now indicate that reaction kinetics are accelerated under micro-confinement; for example in sprays, thin films, droplets, aerosols, and emulsions. These observations are dramatic, posing a challenge to our understanding of chemical reaction mechanisms with potentially significant practical consequences for predicting the complex chemistry in natural systems. Here we introduce the idea of “kinetic confinement,” which is intended to provide a conceptual backdrop for understanding when and why microdroplet reaction kinetics differ from their macroscale analogs.
DFT-guided Development of New Hemilabile (P^N) Ligands for Gold-(I/III) RedOx Catalysis : Application to the Thiotosylation of Aryl Iodides
Authors: Muratov Karim , Zaripov Emil , Berezovski Maxim V. , Gagosz Fabien
Published: August 2023

Ligand-enabled oxidative addition of Csp2-X bonds to Au(I) centers has recently appeared as a valuable strategy for the development of catalytic RedOx processes. Several cross-coupling reactions that were previously considered difficult to achieve were reported lately, thus expanding the synthetic potential of gold(I) complexes beyond the traditional nucleophilic functionalization of pi-systems. MeDalPhos has played an important role in this development and, despite several studies on alternative structures, remains so far, the only general ligand for such process. We report herein the discovery and the DFT-guided structural optimization of a new family of hemilabile (P^N) ligands that can promote oxidative addition of aryl iodides to gold(I). These flexible ligands, which possess a common 2-methylamino heteroaromatic N-donor motif, are structurally and electronically tunable, beyond being easily accessible and affordable. The corresponding Au(I) complexes were shown to outperform the reactivity of (MeDalPhos)Au(I) in a series of alkoxy- and amidoarylation of alkenes. Their synthetic potential and comparatively higher reactivity were further highlighted in the thiotosylation of aryl iodides, a challenging unreported C-S cross-coupling reaction that could not be achieved under classical Pd(0/II) catalysis and that allows a general and divergent access to aryl sulfur derivatives.
Greytown: the oldest inland colonial town
Authors: Kernohan David
Published: August 2023

Greytown is the oldest town in the Wairarapa established under the Small Farms Association, and the oldest inland settlement of the British colonial era. In March 1854, at a meeting held in the Crown and Anchor Hotel in Wellington, 49 settlers selected town acres in Greytown. By the 1870s Greytown had its own newspaper, a school, a hospital and a flourishing retail and commercial base. In 1871 the Greytown Trust Act was passed and the town became a centre for farming, flax, and timber milling though it suffered from the regular flooding of the Waiohine river. Greytown became a borough in 1878 but stopped growing when the railway by-passed it. This paper explores the extant buildings from that period and issues around maintaining the Greytown Historic Heritage Precinct.
Petro-masculinidad y paisaje postcolonial en El niño y la niebla de Roberto Gavaldón
Authors: Hernández González María G
Published: August 2023

La película El niño y la niebla de 1953 dirigida por Roberto Gavaldón presenta al México postrevolucionario que idealiza alcanzar el progreso mediante la industrialización petrolera bajo el poder del sector masculino. En esta película se muestran a los personajes masculinos en torno a características de racionalidad e intelectualidad, mientras que se presenta al personaje protagónico, Marta mediante la locura y sin cabida en el naciente mundo intelectual. En el presente ensayo sostengo que en la película El niño y la niebla la representación de los personajes masculinos asegura un orden de petro-masculinidad y una postura positiva hacia el consumo y comercialización del petróleo para garantizar que el dominio de los combustibles fósiles se encuentre bajo la potestad masculina. Propongo que la racionalidad en los personajes masculinos se difunde mediante la idealización del progreso que justifica la eficiencia y productividad del medio ambiente. Por otro lado, analizo cómo la supuesta locura que configura al personaje de Marta funciona para crear un paisaje postcolonial que distrae sobre los daños medioambientales que causa el extractivismo.

Felted cherry is a valuable fruit crop due to its high adaptability and nutritional value of the fruit. In the territory of Russia, felted cherry is a cultivated plant. All natural populations are feral plants that entered the European part of Russia more than 150 years ago through the Primorsky Krai. The aim of the study is to assess the variability and conjugacy of fruit and leaf characters in a population of felted cherry. The subjects of the study were the wild felted cherry trees growing near the island of Patmos, Chemalsky district, Republic of Altai. Fruits and leaves were collected from 8–10-year-old plants in the first decade of July. For the research, 30 fruits and leaves each were randomly selected from the middle part of the shoots and their characteristics were estimated: fruit length (mm), fruit diameter (mm), fruit weight (g), sugar (°Bx), leaf length (mm), leaf width (mm). Fruit length and width were found to have a very low level of variability and were within 5–6%, mainly fruit length from 11.12 to 12.79 mm and fruit diameter from 10.90 to 11.39 mm. For the research, 30 fruits and leaves each were randomly selected from the middle part of the shoots and their characteristics were estimated. This population can be recommended for further research on resistance to moniliosis and possible introduction into industrial production.
