Influencia y efectos de la dimensión espacial del soporte en la estimación de recursos minerales
Authors: Maldonado Escalante Carlos Enrique , Mayorga Rojas Jaime César
Published: July 2022

La estimación de recursos minerales es un asunto fundamental en la existencia de una empresa minero-metalúrgica. La cantidad de software y métodos actuales han permitido que la calidad de las estimaciones que se realizan aumente, sin embargo, aún hay variables que se determinan en base a criterio y experiencia que influyen en la certeza del modelo generado. En geoestadística el tamaño del soporte es de gran importancia para la creación del modelo. En este trabajo se comparan dos modelos de bloques de distinto soporte, creados a partir de la misma data, con los mismos criterios de estimación, para reconocer la diferencia entre ambos, y los datos reales de producción, concluyendo que en esta escala no se observa una variación significativa.

Authors:   Institute of Pig Breeding and Agricultural Production NAAS, 1 Shvedska str., Poltava, 36013, Ukraine, Budakva Ye. O.
Published: July 2022

Traditionally, the mitochondrial genome is characterized as a “molecular clock” for tracking the history of phylogeny along the maternal line. Particular attention is paid to the distribution of mitochondrial DNA haplotypes among commercial pigs (Large White × Landrace) × Maxgro from RPE “Globinsky Pig Farm”, Globyno town, Poltava region, Ukraine. For the study of the genetic structure of the pigs’ hybrid markers of mitochondrial DNA — a maternal type of inheritance was used. DNA markers are a convenient tool for investigating the origin of pro-maternal pig breeds. Application of multiplex analysis PCR-RFLP (Polymerase chain reaction-restriction fragment length polymorphism) when examining the variable area of the D-loop between sites 15558–15917 mitochondrial genome of hybrid pigs made it possible to determine the pro-maternal haplotypes of the experimental sample (n=20). Thus, according to the multisite system developed by Pochernyaev K. F., determination of mitochondrial haplotypes of pigs, which are denoted by Latin letters from A to P allowed to determine the true pro-maternal haplotypes of the experimental sample of pigs (n=20), as evidenced by the presence of the Tas I website in the above-mentioned provisions what actually determine the haplotypes of mitochondrial DNA. According to the results of the study defined haplotypes characterize different breeds, namely 4 animals with haplotype C — Landrace (Ukraine, Poland). 6 pigs have mitochondrial haplotype N — Large White (Asian type) and 7 pigs with mitochondrial haplotype O — Landrace. 1 animal with haplotype G — wild pig and cross-border breed Wales (Italy). 2 representatives of haplotype D — not found among the breeds of domestic pigs. According to the established pro-maternal haplotypes of hybrid pigs, animals-carriers of haplotype O are representatives of Scandinavian female pigs F1 as used in uterine herds in Sweden and Ireland with the participation of the Maxgro terminal parent line in the hybridization system. Identified mitochondrial haplotypes were found to be breed-specific to hybrid pigs of Irish breeding, this is confirmed by the established polymorphism of the mitochondrial genome which is an objective marker even in complex hybridization schemes. The work was done with the support of the National Academy of Agrarian Sciences of Ukraine 31.01.00.07.F. “Investigate the pleiotropic effect gens that the SNP use in marker-associated pig breeding”. DR no. 0121U109838. Following the example of the developed systematization of the combination of restricted fragments by Pochernyaev K. F. in the future, I propose to create a database of reference haplotypes of mitochondrial DNA of pigs’ final hybrid. In the future, it will be used in further research to reconstruct the demographic history of commercial pigs of cross-border breeds.

The aim of the study was to investigate the effect of cryopreserved mesenchymal stem cells (CrMSCs) from different tissue (bone marrow, adipose tissue, cartilage) potentiated with some growth and differentiation factors (TGFβ and bFGF) on intervertebral disc (IVD) cartilage repair using compression model of degenerative damage. In the group with self-healing histological changes in IVD cartilage tissue were pronounced. Administration of untreated CrMSCs (regardless of their origin) regenerated IVD structure up to a moderate degree on the 45th day. After therapy with TGFβ-potentiated cells, the histological structure of the disc remained similar to untreated CrMSC influence, which according to the integrated semi-quantitative scale corresponded to moderate degenerative changes. Whereas, the administration of bFGF-potentiated cells contributed to the restoration of the disc structure up to a mild degree of histological damages. In the latter case, there was an increase in cellularity of the fibrous ring, regeneration of cracks and gaps, and restoration of collagen febrile structure in annulus fibrosus on the 45th day after therapy. At the same time, the average cell density of fibrous rings increased by 1.35, 1.50, and 1.39 times and IVD height grew by 1.33, 1.36, and 1.37 times for bone marrow-, adipose- and cartilage-derived CrMSC of potentiated by bFGF respectively compared to untreated analog. Thus, administration of CrMSCs from all studied sources activates regenerative processes in degenerated intervertebral discs of rats, the rate of which increases using of bFGF-potentiated cells.

Authors: Uzunova Veneta
Published: July 2022

The development and application of the STEM approach in education is in the focus of contemporary research work. STEM based learning creates premises for problem solving on your own and in a team, managing conflict situations, finding your own place in the team, the skills to express and argue a position, skills for active listening and going deeper into other’s point of view, “outside of the box” thinking. Social and emotional learning in itself is an approach for the creation and the development of competencies in areas such as: self-awareness, decision making, self-respect, social awareness and social skills. The current article presents the results of a conducted research among teachers implementing the STEM approach in their teaching. It is an attempt to establish through reflection and self-reflection an answer to the question to what extent do they think of social and emotional learning as they implement STEM and what social and emotional skills are being developed in both students and teachers through STEM.

White lead: A new naturally occurring 2D material
Authors: Ranjan Pranay , Kumar Prashant
Published: July 2022

Atomic scale crystallographic structures of a quantum crystals depend on substrate, interfacial strain, defects, surface functionalities etc., which make it challenging to precisely control. To achieve high quality material, UHV conditions are prerequisite, which makes it costly. Naturally occurring 2D materials have tremendous significance in this regard. White lead, having weak interlayer coupling and easily found in natural ores have never been exfoliated. Keeping the novelty in mind, one needs to explore its physical as well as chemical behaviour and look out for appropriate applications. We for the first time, therefore, have sonochemically exfoliated white lead, and established its physical and chemical behaviour. We have also blended it with graphene oxide and explored its gas sensing applications and found the hybrid system to be very selective for NH3 gas. White lead, a naturally occurring 2D material; has been exfoliated for the first time and its hybrid with graphene oxide has been explored for gas sensing.

Change in the level of socio-economic development in Poland in the subregional dimension
Authors:   Department of Public Finance, Poznań University of Economics and Business, Poland, Spychała Marcin
Published: July 2022

The compilation involved an analysis of the level of socioeconomic development at the NUTS-3 subregion level in Poland, based on 60 indicators classified within 4 subcomponents (factors) of regional development: material capital, human capital, natural environment and both innovativeness and entrepreneurship. The purpose of the article is to present the varied nature of the socio-economic level of development in Poland based on the NUTS-3 subregion concept. The level of socio-economic development, as well as the level of its shaping factors, is presented based on a synthetic gap exhibiting the taxonomic distance of a particular subregion in terms of the established pattern of development. The examination was carried out in the static dimension (based on the values of the indicators in 2019) as well as in parallel with the dynamic dimension (based on changes in the values of the gaps in the years 2010–2019). In the compilation, a hypothesis which was tested according to which the socio-economic development of the subregions in Poland is highly varied, and its highest level is registered in the largest provincial cities: Warsaw, Cracow, Wrocław and Poznań, and the lowest in the subregions far away from these major cities, which constitute the centers of development.
Regional differentiation of human capital – analysis based on the Mincer wage equation
Authors:   Chair of Econometrics, Faculty of Economics and Sociology, University of Lodz, Poland, Mowczan Damian
Published: July 2022

The main objective of this paper was an attempt to assess the differentiation of human capital at the level of Polish regions (voivodeships, NUTS-2 level). For this purpose, we used unidentifiable unit data from a survey the Central Statistical Office conducted on the structure of wages and salaries in October 2016 (Z-12), data from the Labour Force Survey (LFS), and data on the life expectancy of women and men. The GUS microdata from the Z-12 study was used to estimate the parameters of the Mincer-type extended wage regression, separately for each voivodeship. In the next step, these estimates were used as weights to calculate the human capital index, taking into account the health condition, education, and professional experience of employees. The values of the aforementioned measure were estimated for 2016 and 2019 (the assumption of weight stability over a short time period was made). The analysis conducted made it possible to determine which regions are characterised by the highest and lowest levels of human capital. The highest levels of human capital were found in Mazowieckie, Pomorskie, and Małopolskie. The voivodeships with the lowest level of the considered measures were Lubuskie, Warmińsko-Mazurskie, Podlaskie, Podkarpackie, and Łódzkie. When comparing the values of the human capital index between 2016 and 2019, it can be concluded that the regions with the lowest value of this measure were also characterised by lower dynamics (the only exception was Lubelskie). Such a situation will probably favor the divergence of human capital between regions. This may, therefore, translate into the persistence (or deepening) of differences in the levels of development of these voivodeships, compared to more developed regions.

Published: July 2022

In this work we obtained a polymer-metal complex by mixing aqueous solution of copper(II) acetate with PVA at a certain ratio, pH of the solution and temperature. The composition of the complex compound was determined by potentiometric and conductometric titration. The possibility of a complex formation was proved by calculating thermodynamic characteristics. The stability constant of the polymer-metal complex was calculated on the basis of the modified Bjerrum’s method. The metal-polymer complex was synthesized in the ratio 1:2. IR spectroscopy and scanning electron microscopy (SEM) confirmed the coordination of polymeric PVA ligand to copper and allowed evaluating the morphology and features of the complex surface. The catalytic activity of the synthesized compound was evaluated in the oxidation reaction of elemental phosphorus (P4) by oxygen in aqueous-organic media under mild conditions. Quantitative analysis of phosphoric acid was made by photocolorimetric method. We found that the oxidation process of P4 in the presence of the complex Cu(PVA)2(OAc)2 in aqueous-organic media is characterized with the maximum absorption rate, in comparison with Cu(OAc)2·H2O oxidation process with P4, and yields up to 97% of the products. The process of oxidation of yellow phosphorus by oxygen in the presence of the copper(II)-PVA complex proceeds through key reactions of two-electron reduction of the catalyst P4 with the formation of intermediate phosphorus-containing products P3+ and the stages of catalyst regeneration by oxygen. Twenty-electron oxidation of P4 to the phosphorus-containing P5+ products involves 10 two-electron redox reactions and a number of complexation or hydrolysis stages.

Published: July 2022

The feasibility of soft mechanochemical synthesis was studied here for hydroxyapatite with various types of substitution. It was shown that this method allows obtaining hydroxyapatites substituted with copper or iron cations and hydroxyapatites cosubstituted with zinc cations and silicate groups. Thermal stability of the synthesized samples was evaluated. It was found that to preserve phase homogeneity of the material, the temperature during the preparation of ceramic products and coatings should not exceed 600–800 °C. An exception is the hydroxyapatite where a hydroxyl group is expected to be replaced by a copper cation during the synthesis at a degree of substitution x = 0.5. For this sample, the temperature of the the heat treatment can be increased to 1100–1200 °C because copper cations return to the hydroxyapatite crystal lattice at these temperatures, and the material becomes single-phase.
Phosphorus-doped protonic conductors based on BaLanInnO3n+1 (n = 1, 2): applying oxyanion doping strategy to the layered perovskite structure
Authors: Tarasova Nataliia , Galisheva Anzhelika
Published: July 2022

The creation of highly efficient and eco-friendly energy sources such as hydrogen energy systems is one of main vectors for the sustainable development of human society. Proton-conducting ceramic materials can be applied as one of the main components of such hydrogen- fueled electrochemical devices, including protonic ceramic fuel cells. The oxyanion doping strategy is a promising approach for improving transport properties of proton-conducting complex oxides. In this paper, this strategy was applied to proton-conducting layered perovskites for the first time. The phosphorus-doped protonic conductors based on BaLanInnO3n+1 (n = 1, 2) were obtained, and their electrical conductivity was thoroughly investigated. It was found that the phosphorous doping leads to an increase in the electrical conductivity values by ~0.7 orders of magnitude.

Published: July 2022

Industrial high-calcium fly ashes obtained by burning Kansk-Achinsk coal at a thermal power plant and selected from different fields of electrostatic precipitators of an ash collecting plant were studied as the basis for composite binders (CB). The main factors influencing the properties of such CBs are the particle size, the concentration of superplasticizer at a water:binder (w/b) ratio of 0.25, and the proportion of HCFA in the mixture with cement. In particular, for cementless CBs at w/b 0.4, it was found that a change in the particle size d90 from 30 μm to 10 μm leads to an increase in compressive strength by more than 2 times – from 5.5–14 MPa to 11–36 MPa, accordingly, with a curing age of 3–300 days. The 0.12% additive of Melflux 5581F superplasticizer at w/b 0.25 increases the compressive strength – up to 14–32 MPa and up to 24–78 MPa, accordingly. The HCFA-cement blends were investigated in the range of 60–90% HCFA and the maximum compressive strength 77 MPa at 28 days of hardening was found at 80% HCFA. On the basis of 80% HCFA blend with the 0.3% addition of Melflux 5581F and 5% silica fume, the specimens of ultra-high strength (108 MPa at 28 days of hardening) were obtained.

Variable Selection in High Dimensional Data with Interactions
Authors: Jaafar Zuharah , Ismail Norazlina
Published: July 2022

A common research area in statistical machine learning has been variable selection in high dimensional settings. In recent years, numerous effective approaches have been created to deal with these challenges. In order to improve the prediction accuracy of the model for the given dataset, this study sought to present a double approach variable selection method when pairwise interactions between the explanatory variables exist and to choose the smallest explanatory variable set (considering interactions among them). In this study, a double step method consolidating Random Forest and Adaptive Elastic Net was further examined to mimic potential health effects of environmental contamination. When there were existing interactions in the data or none at all, the double step approach was compared to the single-step adaptive elastic net method and two-step CART paired with the adaptive elastic net method. Using significant statistical tests like RMSE, R2 , and the quantity of the variable chosen for the final model, the success of the strategies was measured. The double step RF+AENET approach produces a simple, constrained model. Despite the complex association between exposure variables, it has the lowest false detection rate for null interactions. A set of variables that have correlation with the result are effectively retained by the screening and variable reduction processes in the RF step of the RF+AENET approach. The double step RF+AENET performs prediction better than a single technique and chooses a sparse model that is close to the true model. Thus, it can be said that when there are pairwise interactions between variables in the simulated biological dataset, the double step technique is a better method for model prediction and parameter estimation.

Published: July 2022

In times of severe antiseizure medication (ASM) shortage due to emergency situations (e.g., disasters, conflicts, sudden disruption to international supply chains), management of people with epilepsy with available ASMs can be difficult. A group of experts was brought together by the International League Against Epilepsy (ILAE) to formulate recommendations for such circumstances. Every effort was made to base these recommendations on direct published literature or extrapolations from basic information available about ASMs. Actual published literature in this area is, however, limited, and at times, assumptions were made by the experts to generate these recommendations. During times of shortage of ASMs, switching between different ASMs (e.g., oxcarbazepine and carbamazepine) can occasionally be considered as a mitigation procedure. However, for many ASMs, the option of an overnight switch to another drug does not exist. Switching from brand to generic or between generic products has often been shown to be safe, if required. Finally, when supplies of benzodiazepines or equipment to administer medications intravenously are not available, rectal administration of some ASMs may be an emergency alternative route for treating serial seizures and status epilepticus. Decision‐making with regard to treatment and possible options should be driven by what is best for the patient.

Published: July 2022

Citrus rootstock breeding is important to improve their resistance to diseases, pests and adverse environmental conditions. The majority of citrus species have nuceller embryony. Although Clementine mandarin is monoembryonic, in some cases (intercrossing etc.) abortive seed formation can be seen frequently. In this study, Clementine mandarin × Carrizo citrange were crossed. In the study, interspecies hybridization (Citrus × Poncirus) was used. Embryo rescue technique was used to prevent the loss of hybrid individuals due to abortive seed formation. The seeds were gathered from the crossed plants 80, 100, and 120 days after pollination. The immature embryos were removed from the seeds and these embryos were transferred to control, 0.5, and 1.0 mg l-1 GA3 containing medium to germination. The highest germination rate with 100% was observed from 1.0 mg l-1 GA3 containing media harvested 120 days after pollination. Additionally, the highest rate of trifoliate seedlings was obtained from embryos gathered after 120 days of the pollination.

Published: July 2022

The conservation status of inland fishery resources is vulnerable worldwide, and this threatens the livelihoods of fishing-dependent communities. This case study aimed to: (i) establish the use and perception of fisheries and ecosystem services by locals, (ii) undertake a monetary valuation of the fisheries, (iii) determine the potential threats to the fisheries, and (iv) examine the social drivers and barriers for citizen science involvement. Lastly, (v) we evaluated how the above factors affected the conservation of fisheries at Mushumbi Pools, Zimbabwe. A cross-sectional survey of 69 households was conducted. Results of the study showed that locals utilised 17 fish species for social, economic, cultural and religious purposes. Locals attach high intrinsic socio-economic value to the fisheries resources and wetland ecosystem services provided by the Mushumbi Pools. Despite the sustained income from fisheries, the local market in Mushumbi Pools is actually undervaluing fisheries resources, as the fish prices in the area are very low compared to standard market prices countrywide. A larger proportion of the respondents (65%) cited poor land-tilling practices, heavy application of agropesticides and use of unsustainable fish harvesting methods as the main threats to fish diversity in Mushumbi Pools. Relaxed fishing concessions for women and children in specific fishing zones were key drivers for community participation in fisheries conservation. However, strict enforcement of fishing bans in breeding and nursery zones and restricted access to some parts of the Mushumbi Pools were the main barriers for local involvement in the conservation of fisheries resources. Without the fishing community’s participation there is no guaranteed sustainability of the fishery resources in the pools. Legitimising community access, ensuring fair valuation and utility rights is a key driver for successful management of inland fisheries resources in Sub-Saharan Africa.
Evaluation of nitrate redistribution in surface and subsurface drip irrigation systems
Authors: Sogand Arab  , Javad Mozaffari  , Mohammad Javad Nahvivia
Published: July 2022

Nitrogen compounds added to the soil may convert to nitrate and cause contamination. The distribution and uniformity of soil nitrate in surface vs. subsurface drip irrigation systems were compared in a physical model consisting of a transparent glass box (1.20 x 0.5 x 1 m) and sandy loam soil, and considering emitter installation depths of 0 and 30 cm, discharge rates of Q1 = 2, Q2 = 4, Q3 = 8 L/h, and fertilizer levels of S1 = 125, S2 = 250, S3 = 375 mg/L. Irrigation continued for 6 h and nitrate and moisture sampling was performed for 68 h after the initiation of water front advance. The result showed that doubling the discharge caused the wetted area to triple in size in the subsurface drip irrigation system whereas it only doubled in size in the surface drip irrigation system. Thus in the subsurface system, when increasing the fertilizer level, the nitrate spread out extensively and therefore its concentration was greatly reduced. Also, by increasing discharge, the difference in soil nitrate concentration between the two systems increases because of increasing non-uniformity of nitrate distribution in the surface system, such that by increasing the fertilizer concentration form 125 to 375 mg/L, the difference in nitrate concentration increases from 22% to 500% (for Q1 = 2 L/h), 43% to 352% (for Q2 = 4 L/h), and 14% to 166% (for Q3 = 8 L/h). Thus the subsurface drip irrigation system has a more uniform trend of nitrate distribution than the surface drip irrigation system. Also, treatment with maximum flow and fertilizer level will create the most optimal nitrate concentration in the soil.

„Még egy ily győzelmes háború, és elvesztem!”
Authors: Tamás Ágnes
Published: July 2022

A tanulmány célja, hogy áttekintést nyújtson az erőszakábrázolások változásáról az 1860-as és 1940-es évek között vizsgálva a kiválasztott háborúk esetében az erőszak, a küzdelmek, csaták megjelenítési módját. Az elemzés forrásbázisát karikatúrák képezik különböző politikai irányultságú élclapokból (Az Üstökös, Borsszem Jankó, Bolond Istók, Kakas Márton, Bolond Miska, Ludas Matyi, Drótkefe) és egy napilapból (Magyarság). Az analízis tárgyául kijelölt háborús konfliktusokhoz a magyar társadalom eltérő attitűddel, érdeklődéssel fordult, különböző mértékben volt érintett, így nem azonos mennyiségű és minőségű karikatúrát várhatunk el.

Megfigyelhetjük, hogy a közvetlen érintettség mértéke nem feltétlenül határozza meg az érdeklődés nagyságát és az ábrázolásmódok radikalizálódását. Az 1890-es években a rajzolók személyének változása és a karikatúra technikai színvonalának fejlődése, az olvasói ízlés, a politikai beszédmód radikalizálódása mind hozzájárulhattak a háborús erőszak egyre gyakoribb megjelenítéséhez, s már a századfordulótól tapasztalható, hogy egyre véresebb ábrázolások láttak napvilágot a humoros lapokban. Az első világháború végéig a képek egy részén realisztikus módon mutatták be a harci cselekményeket, míg másik részükön a háborús konfliktus résztvevőit – közvetlen érintettség esetében az ellenséget – gúnyolták ki karikatúrákon. A két világháború közötti években újabb változást észlelhetünk: a jelentősen egyszerűsödtek, és könnyen dekódolhatóan mutatták be a háborús erőszakot, ritkábban mitikus-biblikus vagy éppen verekedést ábrázoló, bagatellizáló jelenetekkel.
Adaptation to climate change in Africa
Authors: Jamal Saghir
Published: July 2022

Whether we like it or not, ours will be a century where the governance and economic agenda will be dominated by the task of adapting to climate change. With the early effects of climate change already starkly visible, and their escalations over the coming decades already locked in, adaptation is no longer a choice but an imperative. And nowhere in the world is there a greater urgency to set out a coherent and comprehensive agenda for adaptation, we believe, than in Africa.

Multiplex PCR Assay for Clade-typing Salmonella Enteritidis v1
Authors: Gallichan Sarah
Published: July 2022

Salmonella Enteritidis is one of the most commonly reported serovars of non-typhoidal Salmonella causing human disease and is responsible for both gastroenteritis and invasive non-typhoidal Salmonella (iNTS) disease worldwide. Whole-genome sequence (WGS) comparison of Salmonella Enteritidis isolates from across the world have identified three distinct clades, named Global Epidemic, Central/East African and West African, all of which have been implicated in epidemics: the Global Epidemic clade was linked to poultry-associated gastroenteritis, while the two African clades were related to iNTS disease. Despite the recognition of different Salmonella Enteritidis clades, the distribution and epidemiology of these clades across Africa is poorly understood because currently identification of these clades requires whole genome sequencing capacity. Here, we developed a sensitive, time- and cost-effective real-time PCR assay capable of differentiating between the Salmonella Enteritidis clades to facilitate surveillance and to inform public health response.
LDM protocol for estimating plasmid conjugation rates v3
Authors: Kosterlitz Olivia
Published: July 2022

This is a general protocol to implement the LDM approach for estimating plasmid conjugation rates. This version of the protocol was originally submitted with the accompanying manuscript. The recommended version (i.e., the most up-to-date) of the LDM protocol will be linked in the corresponding GitHub repository. To get a conceptual overview of the approach, please read the accompanying manuscript. The protocol is intentionally designed to facilitate proper implementation by explicitly verifying that the modeling assumptions are met. We provide 5 streamlined phases, where the last phase involves executing the LDM conjugation assay. The initial 4 phases are to gather the necessary information for the proper execution of the LDM conjugation assay (i.e., phase 5). Here, we provide a brief description and goals for the initial 4 phases. Phase 1: Minimum inhibitory concentration assay with the transconjugant-selecting medium. The goal is to find a concentration of selective agents (e.g., antibiotics) in the transconjugant-selecting medium that inhibits donors and recipients while simultaneously permitting the growth of transconjugants. Phase 2: Extinction probability assays for selective liquid and agar media. The goal is to check the assumption that the focal cell type will successfully establish a lineage under the appropriate selective conditions. Phase 3: Growth rate assay. The goal is to determine the donor- and recipient-specific incubation times that will ensure the cultures enter exponential growth before initiating the conjugation assay. Phase 4: Finding an incubation time and initial densities for executing the LDM conjugation assay. The goal is to find a combination of incubation time and initial densities such that the probability of a conjugation event occurring is between 0 and 1 (i.e., where there will be a mixture of turbid and non-turbid co-cultures after incubation with transconjugant-selecting medium). Phase 5: LDM conjugation assay. The goal is to gather experimental estimates for the variables in the LDM equation to calculate an estimate of the conjugation rate.

ON THE HISTORY AND MODERN CONDITION OF THE ERASMIAN PRONUNCIATION OF ANCIENT GREEK
Authors:   Taras Shevchenko National University of Kyiv, Lazer-Pankiv Olesia , Zalevskyi Ioan ,   Taras Shevchenko National University of Kyiv
Published: July 2022

The article presents the results of a study of some aspects of the formation and use of Erasmian pronunciation of the Ancient Greek language (in particular, the vagueness of the concept, lack of standardization and certain linguistic inconsistencies), based on analysis of the original work of Erasmus of Rotterdam "Dē rēctā latīnī graecīque sermōnis prōnūntiātiōne dialogus" and works devoted to the analysis of Ancient Greek pronunciation and the history of the Greek language in general. Attention is paid to the non grata status that Erasmian pronunciation has in Greece, as well as to alternative views on the origins of the mentioned work of Erasmus, to which, from the 16th century to the present day, opponents of both the Erasmian pronunciation and the reconstructed systems in general refer. Some important facts from the history of Erasmian pronunciation are outlined, in particular that Erasmus was not the pioneer in the search for the "true" pronunciation of Classical Greek (a Spanish humanist Antonio de Nebrija researched this issue at least a quarter of a century before the publication of Erasmus's work); in writing the Dialogue, Erasmus relied on the work of his predecessors, with whom he was maintaining friendly communication; Erasmus's work was not a clear enough proposal for a new reformed system, and the scholar himself continued to use the Byzantine pronunciation and recognized its status. The article gives examples of some differences between variants of Erasmian pronunciation. It is concluded that the Erasmian pronunciation from its inception was not a clearly defined system, and, despite the revolutionary and impressive breakthrough of this linguistic initiative, had some errors, which were compensated by later attempts in the Ancient Greek pronunciation reconstruction in the 19th–21st centuries. It is suggested that, given the significant non-uniformity of present-day Erasmian pronunciation variants (which sometimes leads to complications in international communication between specialists), it is advisable to use, or at least be familiar with modern, more clearly defined and scientifically sound reconstructions, and / or Modern Greek pronunciation which is especially important for rapport with Greek colleagues in classical studies.
UKRAINIAN TRANSLATIONS OF ANCIENT GREEK LITERATURE: ACHIEVEMENTS AND PROSPECTS
Authors:   Taras Shevchenko National University of Kyiv, Zvonska Lesia
Published: July 2022

The article presents the history of Ukrainian translations of ancient Greek literature and describes the translation work of Ukrainian classical philologists, poets and prose writers. The reception of literary works of antiquity is represented by texts of different styles, poetic schools and Ukrainian language of different periods, which demonstrate the glorious tradition of domestic translation studies. It is noted that Ukrainian translations have a long history (from the first translation in 1788 and the first textbook in 1809); they were published in separate periodicals, collections, almanacs, as well as complete books and in textbooks and anthologies. Ukrainian translations of literature in the ancient Greek language of the аrchaic, сlassical and Hellenistic periods are analyzed. Translations of poetry (epic, elegy, iambic, monodic and choral lyrics, tragedy, comedy, folk lyrics, mimiyamb, epilium, bucolic, idyll, epigram) and prose (fable, historiography, philosophy, rhetoric, fiction, ancient novel, New Testament and Septuagint, early Christian patristic) are described. Significant in the history of translations are the achievements of the brilliant connoisseur of antiquity I. Franko. The high level of linguistic and stylistic assimilation of ancient Greek prose and poetic texts is demonstrated by the creative style of such outstanding translators as Borys Ten, V.Svidzinsky, M. Bilyk, G. Kochur, A. Smotrych, V. Derzhavуn, V. Samonenko, P. Striltsiv, A. Tsisyk, Y.Mushak, A. Biletsky, V. Maslyuk, J. Kobiv, Y. Tsymbalyuk, L. Pavlenko.The glorious traditions are continued by well-known antiquaries, writers and poets, among whom A. Sodomora has a prominent place. At the level of world biblical studies there are four translations of the Holy Scripture in Ukrainian (P. Kulish, I. Pulyuy, I. Nechuy-Levytsky, I. Ogienko, I. Khomenko, R. Turkonyuk). Іt is summarized that despite numerous Ukrainian translations of various genres of ancient Greek literature there is a need to create a corpus of translations of ancient Greek historiography, rhetoric, philosophy, natural science texts, Greek patristic.
