Word-formation motivation as a means of lexicalizing derivative words in the classroom in Russian as a foreign language
Authors: Demidova Elena
Published: June 2021

The article examines the place of the word-formation component of the communicative competence of foreign students in the process of their learning Russian as a foreign language.
The word-formation component, along with other linguistic components, participates in the formation of the communicative competence of foreign students, however, the problem of Russian word formation remains insufficiently developed in the linguodidactic plan. The author expresses his opinion that the increase in the vocabulary of foreign students should be accompanied by the systematization of lexical units, taking into account their derivational connections and relations. Therefore, when lexicalization, one should use not the selection of synonyms or the descriptive method, which leads to the mechanical memorization of the meaning, but by means of correlation with the same root words, to activate in the minds of foreign students the living connections of the lexical units of the Russian language. This applies not only to derivatives of words associated with generating relations of full direct motivation, but also to those derivatives where these connections are not explicitly expressed.
Such an interpretation through a productive word not only makes the meaning of the new lexeme understandable, facilitates its memorization, but also creates a single picture of lexical and word-formation relationships within the language, forms a systemic understanding of the language among students.
The skills of correlating a derivative word with its derivative, obtained in the study of Russian as a foreign language, make it possible to understand the meanings of unfamiliar words. The speed of memorizing the meanings of derived words in this case directly depends on the understanding of the word-formation structure of the word.
This technique will greatly facilitate the development of the vocabulary and will contribute to the formation of a holistic view of the language as a system among foreign students.

Published: June 2021

İstanbul’un 1453’te fethinden hemen sonra Türk-İslâm anlayışına göre şehrin yeniden yapılandırılması çerçevesinde birçok dinî yapı kurulmuştur. Bunlardan biri de 16. yüzyılın ilk çeyreğinde inşa edilen Sinân-ı Erdebilî Tekkesi’dir. Bânîsi, 15. yüzyılın son çeyreğinde Erdebil’den Tebriz’e oradan da İstanbul’a göç edip burada yerleşen Sinâneddin Yûsuf-ı Erdebilî, bu sırada İstanbul’da bulunan Halvetî şeyhi Çelebi Halîfe’ye intisap etmiştir. Şeyhinin 903/1497’de vefatından sonra ise, yerine geçen Sünbül Sinân Efendi’ye (ö.936/1529) bağlılığını devam ettirerek bir Halvetî-Sünbülî şeyhi olarak yetişmiştir. İstanbul’da Ayasofya Câmii yakınında yaşadığı evine 923/1517’de yeni hücreler ilave ettirerek kendi tekkesini, 946/1539’da ise bu yapının vakfını kurmuş, vefat yılı olan 951/1544’e kadar burada Halvetî-Sünbülî Târîkatı adına faâliyet göstermiştir. Kendi soyundan gelen erkek çocuklar tekkenin şeyhliği ile vakfın mütevellîliğini yürütmüşlerdir. İşlevi, 1925’te tekkelerin kapatılması ile resmen son bulan Sinân-ı Erdebilî Tekkesi’nin kuruluşundan bu yana dört defa yeniden yapıldığı tespit edilmiştir. 19. yüzyılda bir dönem Celvetî şeyhlerinin eline geçen Sinân-ı Erdebilî Tekkesi’nin son şeyhliğini ise, bir Nakşibendî şeyhi olan Halil Sırrı Efendi yürütmüştür.
ESCAPE FROM ANTIQUITY: CASE OF G.G. DILIGENSKIY
Authors:   Institute of World History of the Russian Academy of Sciences, Karpyuk S. G.
Published: June 2021

Diligenskiy's case seems difficult to explain: a senior researcher at the Institute of History of the USSR Academy of Sciences in the prime of his career (Ph.D. dissertation defended and published, many publications in Soviet and foreign journals, frequent trips to foreign conferences) quits his subject (history of late antiquity), leaves the institute and switches to the study of the social psychology of the working class in France. A long and difficult conversation with the head of the Sector of ancient history S.L. Utchenko, who obviously considered G.G. Diligenskiy as his possible successor, could not change anything. What prompted the young historian to stop studying late antiquity and leave the ancient history sector of the Institute of History of the USSR Academy of Sciences? The choice of specialization took place in the years complicated by tough campaigns to combat cosmopolitanism, etc. According to the memoirs of M.K. Trofimova, who studied a little earlier, her relatives insisted that she should be engaged in the history of the ancient world or archaeology, as the most secure from an ideological (and practical) point of view historical disciplines. Thus, the choice of the history of antiquity was rather "protective" in nature; antiquity could attract as a relatively safe field for historical research. The era of the "thaw" gave rise to illusions among a part of the Soviet intelligentsia about the possibility of social changes and the improvement of the Soviet socio-political system. The history of antiquity was a field of research too far from modern problems, and the scholar chose another sphere of activity. The works of G.G. Diligenskiy made a very significant contribution to the development of sociological and socio-psychological research in the late USSR, and the "Diligenskiy school" laid the foundations for political scientific research in modern Russia. The Marxist, "Eurocommunist" views of the scholar found better application in the academic but influential Institute of World Economy and International Relations, which made recommendations to the authorities, than in the rather dogmatic sphere of ancient history, where the best way out was not the "improvement" of Marxism, but a radical departure from Marxist dogma.

The discovery of the pre-Mousterian monument, dating back to the Middle Pleistocene era, in the mountain-forest zone of the Southern Urals is of great interest both for archaeology, in particular, considering the problem of time and ways of setting on the territory, and for geology, taking into account the dating of the terraces of river valleys in the mountainous part of the region. The site-workshop Akbulatovo-3 is confined to the cover deposits of the III floodplain terrace of the Belaya river, 15 m above the modern level of the river, including pebble and clastic material from quartzite in the deposits of brownish-brown loam of periglacial type of the late Risian time. The collection of items from quartzite (447 items) is represented by a variety of cores: cuboid, orthogonal, sub-cone, and biplatformed. The tools were made both by bifacial processing and on flakes, less often on amorphous plate-like chips. Among them, there are “Acheulean” forms – choppers, peaks, simple scrapers, and “Upper Paleolithic” ones – scrapers, burins, punctures, carvers, and chisel tools. Such a combination of archaic types of tools and cores with “progressive” forms of tools and cores, characteristic of the Moustier and Upper Paleolithic gives grounds to attribute the complex to the end of the Acheulean era or to the beginning of the Moustier. A similar monument, combining the Acheulean types of tools and cores with the Mousterian and Upper Paleolithic ones, was discovered on Lake Turogoyak in the Chelyabinsk region – the site Naves (Island of Vera 6a) at the porphyrite exits. This allows the authors to attribute them to a single technological tradition, called the “Akbulatov type of industry”.
AMULETS AND TALISMANS FROM THE “EGYPTIAN” FAIENCE FROM THE TERRITORY OF KRASNODAR REGION. SOURCES AND HISTORIOGRAPHY

Published: June 2021

The paper presents the source base of figured forms of the so-called "Egyptian" faience, stored in the archaeological funds of the Krasnodar State Historical and Archaeological Museum-Reserve. Historiographical review, in relation to the findings from the territory of the Krasnodar region, complements it. The author tested the method of cross-comparison of data from academic literature and archival data and materials of scientific reports. This opens up new opportunities for the study of funeral and memorial cults of the indicated region in the 1st century B.C. – 3d century A.D. The core content of the study is related to the comparison of different types of sources used to form the database created on a reference group of shapes from faience. The author aimed to trace the processes of formation of the source base from the stage of excavation to the creation of reporting and accounting documentation and the subsequent publication of the extracted materials. The paper summarizes for the first time the materials from the territory of Krasnodar region available for the author. These data provide to determine that some types of amulets could be produced from local raw materials at the manufacturing basis of the cities-policies of the Northern Black Sea region. In some field reports, the problem of incompleteness of the primary source base was identified. In some cases, collections’ inventories of the items do not correspond to the data recorded in the course of their scientific processing. Their comparison with the records of the archive and archaeological museum collections allows the author to eliminate the occurring contradictions. Information about amulets and the conditions for their findings contained in academic publications may add details. However, these articles do not acquire the status of a scientific source.
EARLY MEDIEVAL STAMPING MOULD FOR BELT-ENDS FROM THE LOWER DNIESTER REGION

A bronze stamping mould for belt-ends was found in 2016 on the outskirts of Slobodzeya on the territory of a multi-layered settlement on the left bank of the Lower Dniester. The item has traces of long-term use; the front side is badly worn out. The stamping mould shows a full-face anthropomorphic male face with a long mustache and beard. An analysis of the finds of early medieval metal stamping moulds for a belt set showed that the overwhelming majority of them are connected with the territory of the Eastern Roman Empire (urban centers) and the Avar Khaganate (graves of "jewelers"). Matrices are dated back to the 7th and 8th centuries. However, the study of items from belt sets with male guises led to the conclusion that such images were quite widely represented in the 9th–10th centuries in different areas, for example, in Moravia, the Upper Dnieper region, the Middle Volga region, the North Caucasus, and the South Ural region. Similar images on objects of toreutics, which had Byzantine and / or Iranian roots, appeared, according to available sources, in the 7th century. Then, parts of a belt set with alike images marking the high social status of the wearer were used by various peoples for several more centuries. It is highly probable that the published stamping mould is related to the nomadic Early Hungarian cemetery (to the sites of Subbotsevo type) (9th century), which was sunk into the Bronze Age barrow at a distance of about 1 km from the place of its discovery. In this case, the finding of the stamping mould may indicate the wintering place of this nomadic group, where the parts of the belt sets were made.
THE SILURIAN FRONTIER OF EMERSION STAGE IN THE TERRITORY OF SOUTH CIS-TIMAN (PERM REGION)
Authors:   Perm State University, Paktovskiy Yu. G.
Published: June 2021

At the base of the Silurian deposits in the Southern Rassolnaya Deposit, ventfacts considered as an indicator formations of deserts with a predominance of wind erosion (corrosion) processes were first discovered. In this work, the systematization of the found ventfacts was carried out, their morphology was revealed, and it is concluded that the most numerous group among the Aeolian polyhedra is the group of pyramidal ventfacts. Among the latter, the pyramidal trihedrons, otherwise known as dreikanters, are the most common. From the point of view of lithology, ventfacts are quartzite sandstones with relics of hydromicas cement, the structure of which is dominated by a cementless contact connection of quartz grains and fragments of various rocks. According to the structural position of the layers of rocks containing windmills, deposits of the Ordovician and Silurian systems are distinguished in the geological section. A mineralogical study of this section was conducted analyzing the mineral associations of the heavy fraction of lithological samples. The conclusion about possible ventfacts formation time as the border of the Ordovician and Silurian was made. To denote the time and facies boundaries of the emersive phase, the concept of the emersive frontier (or boundary) is introduced by analogy with the term mineralogical boundary. This frontier is taken by the author as the upper (Silurian) emersive boundary, after which there is a drastic change in the tectonic situation in the region. Based on the results of the study, a paleogeographic reconstruction of the Eastern margin of the East European platform on the Silurian emersive frontier is proposed, which may be associated with the Aeolian type of diamond placers of the Silurian intermediate reservoir in the Southern Cis-Timan.

Authors:   Perm State University, Belkin P. A.
Published: June 2021

Mining and processing of potassium salts in humide regions is inevitably connected with the disturbance of natural hydrochemical conditions. In order to describe the chemical composition of groundwater discharged in the immediate vicinity of potash waste storage facilities, spring flow studies were conducted, including sampling and analysis of the macro- and micro-component composition of eight springs over the period 2016-2018. A general description of the chemical composition of spring runoff waters is given, and correlations between the content of various components of their composition are studied. The obtained results make it possible to identify a number of chemicals that determine the technogenic transformation of the chemical composition of groundwater near potash waste storage facilities.

Published: June 2021

The relevance of the research is due to the study of possibility of placing tailings facilities of mining enterprises in areas with minimal negative impact on the environment, in particular on groundwater. This work allows us to estimate the time of penetration of waste pollution into the surface of groundwater. Objective: to determine the areas of the study that are most exposed to groundwater pollution. Objects: filtration parameters of weakly permeable deposits of the aeration zone. Methods: collection and analysis of archival materials, field filtration tests, simulation of the unsaturated zone, geocentrophora. Results: a set of maps has been created that allows determining the areas that are most susceptible to contamination when placing the tailings of a mining enterprise on the studied territory. Based on data from more than 500 archived engineering-geological wells, a model of the aeration zone was constructed and the power of weakly permeable deposits that will serve as a natural anti-filtration screen was estimated. Filtration characteristics of weakly permeable sediments are determined by the method of filling in pits, and a forecast of the rate of penetration of pollution into underground waters is given.

The article considers the issues of changing the energy activity of the surface of clay particles modified by pressure up to 800 MPa. The energy properties of the surface were evaluated by measuring the adhesion force between the surface of clay samples and the silicon cantilever of an atomic force microscope. It has been proved that when clay soils are modified by stress pressure, the adhesion force changes in different directions in clays with different mineral composition. So, in kaolin clay, with an increase in pressure from 25 to 800 MPa, the adhesion force increases, respectively, from 0.25 to 0.78 nN. In clays of montmorillonite composition, an increase in pressure to 150 MPa leads to an increase in the adhesive interaction, and a further increase in the load to 800 MPa leads to its decrease.
Parenting Plans Attentive to the Needs of the Divorcing Family
Authors: Tanya Robinson  , Elma Ryke  , Cornelia Wessels
Published: June 2021

Practical parenting plans should prioritise the needs of the divorcing family by giving voice to the feelings, needs and rights of the children while reflecting on the requests of the parents. If the needs of both parents and their children are not signified, parenting plans will be redundant, as families will not be able to implement parenting plans to structure their lives post-divorce and dysfunction will set in. Establishing the needs of the divorcing family is important when professionals structure a parenting plan as representative parenting plans will assist in managing post-divorce conflict dynamics. This article will present rich qualitative data to demonstrate the needs of the divorcing family and alert professionals to the importance of need representation in parenting plans.
Investigating the Need to Reintroduce a Ballot Requirement for a Protected Strike in South Africa
Authors: Mlungisi Tenza
Published: June 2021

The issue of violent and protracted strikes has been a source of debate on many labour platforms in South Africa. Unions believe that if a ballot is introduced as one of the requirements for a protected strike in South Africa, it will be abused by employers and manipulated as was the case under the old Labour Relations Act. A counter- argument is that no one can take away a right in the Bill of Rights unless the prescribed procedure in the Constitution is followed. A right in the Bill of Rights can also not be limited unless the limitation is in terms of section 36 of the Constitution. Of particular importance to this issue is not the number of strikes in South Africa but their nature (which has been violent) and their duration (which has been unreasonably long). The violent nature of strikes is a major concern for employers, society and non-striking employees. Violent and lengthy strikes are dangerous to both employers and employees. The employer suffers loss of profit and loss of clients with the possibility of reducing its workforce or closing its business. Employees, on the other hand, face retrenchments if the business is not making a profit. The article argues that the reintroduction of a ballot requirement will play a meaningful role in reducing the number of strikes and their duration. Balloting employees prior and during the course of a strike will help test whether employees have the appetite for the strike. The article further argues that if long strikes can be reduced through ballots, dismissal on the basis of operational requirements could be avoided. In the long run, poverty arising from high levels of unemployment could be avoided.

The discussion in this analysis focuses only on reinstatement and determines whether it is an appropriate remedy for constructive dismissal given that termination of the contract takes place because of the employer’s intolerable conduct, leaving the employee with no other option but to resign. The discussion considers the concept of constructive dismissal, and reinstatement as a remedy for constructive dismissal in South Africa, and briefly looks at the position in the United Kingdom (UK).
Breach of Promise to Marry Under Customary Law
Authors: Siyabonga Sibisi
Published: June 2021

The purpose of this note is to look at breach of promise to marry, or breach of an engagement, under customary law. The note commences with a brief discussion of the common law and its development on the subject of promise to marry. This is followed by an enquiry into whether, under customary law, there is such a thing as a promise to marry, as we have come to know it, and if so, what the consequences of such a breach are. After this, the question discussed is who could claim following a breach of promise to marry. This is important because, under customary law, unmarried women were under the guardianship of their fathers or the eldest male in the family. Consequently, a father or eldest male in the family enjoyed the exclusive right to claim damages in a semi-personal capacity for a wrong committed against his daughter. After the expositions outlined above, this note then considers whether the customary law on a promise to marry is in need of development to bring it into line with the Constitution and how that development should take place.
The Ethics of Legal Practitioners in Resource-Scarce Institutions ‒ PM Mashishi v Z Mdlala [2018] 17 BLLR 693 (LC); (2018) 39 ILJ 1607 (LC)
Authors: Nicola Whitear  , Helen Kruuse
Published: June 2021

We consider what the court says in relation to hopeless cases in resource-scarce institutions, and consider how we could understand the required ethical conduct of legal practitioners in these situations better – specifically with reference to William Simon’s “ethical discretion” approach to lawyering. Simon’s critique of contemporary legal ethics in the United States appears to be particularly apt in the circumstances of the Mashishi case – specifically on the perceived amorality of the lawyer’s adversarial role, which results in an uninhibited pursuit of client ends, so long as they are arguably within the law.
The Failure to Provide Notice of an Intended Gathering ‒ Mlungwana v The State (CCT32/18) 2018 ZACC 45 (CC)
Authors: Myrone Stoffels
Published: June 2021

Section 3 of the Regulation of Gatherings Act 205 of 1993 (RGA) requires the local authority within a municipal area to be notified of an intended gathering by the convener of such gathering. This notice is only required when the gathering will be attended by more than 15 people (s 1 of the RGA). The notice must contain all the important information pertaining to the protest (s 3(3)). Failure by the conveners of the gathering to provide such notice was regarded as a criminal offence in terms of section 12(1)(a) of the RGA. The Western Cape High Court in Mlungwana v The State (2018 (1) SACR 538 (WCC)) declared section 12(1)(a) of the RGA to be unconstitutional. The court found that the criminalisation of the failure of a convener to provide notice in terms of section 3 of the intended protest infringed the right to assemble as provided for in section 17 of the Constitution (Mlungwana v The State (WCC) supra par 95). The matter was referred to the Constitutional Court for confirmation of the Western Cape High Court judgment. The State further appealed the Western Cape High Court’s judgment. The Constitutional Court confirmed the judgment of the Western Cape High Court (Mlungwana v The State (CCT32/18) 2018 ZACC 45 (CC) par 112). The judgment of the Constitutional Court may have unintended consequences. The purpose of this case note is to discuss the unconstitutionality of section 12(1)(a) of the RGA.

Published: June 2021

For thyroid function estimation and clinical decision making, use of appropriate reference intervals for thyroid-stimulating hormone (TSH), free thyroxine (fT4) and free triiodothyronine (fT3) is crucial. For each laboratory, establishment of own reference intervals is advised. For the first Slovenian estimation of reference intervals for thyroid hormones a large group of 1722 healthy individuals without thyroid disease was established retrospectively. Hormone analyses were performed on automated analyser Advia Centaur XP Immunoassay System (Siemens Healthineers), which reference intervals for TSH, fT4 and fT3 were 0.55–4.78 mIU/L, 11.5–22.7 pmol/L, and 3.5–6.5 pmol/L, respectively. Statistical analysis followed non-parametric percentile method. Our laboratory reference intervals for TSH, fT4 and fT3 are mostly narrower than intervals given by manufacturer. Median value, lower and upper limit for TSH, fT4 and fT3 were 1.98 (0.59–4.23) mIU/L, 14.5 (11.3–18.8) pmol/L and 4.82 (3.79–6.05) pmol/L, respectively. Most likely, an inclusion of a high number of healthy individuals without thyroid disease was a reason for such results.
Study of Electrical Discharge Machining Parameters on Stainless Steel Using Copper Tool Electrode and Its Effect on the Structure and Electrochemical Properties
Authors: Karimi Mozhgan , Nabavi-Amri Sayyed Ahmad , Soleymanpour Ahmad
Published: June 2021

In this work, the effect of the presence and the diffusion of the Copper from the tool electrode onto the EDMed stainless steel (SS) surface have been investigated by electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD), Quantometer analysis, and Optical microscopic observations. The Taguchi method was used to study the effects of Pulseon time (ton), Pulse-off time (toff), discharge current (I), and overall machining time (τ) on chemical composition, microstructures, micro-cracks, and electrochemical corrosion of EDMed stainless steel workpieces. The results show that the variation of machining parameters changes the chemical composition of the workpieces. By increasing the discharge current and decreasing the Pulse-on time, the copper and the carbon diffuse onto the surface of the workpiece. Consequently, the chemical composition of the workpiece surface changes, leading to an increment of the corrosion resistance. The XRD analysis shows the formation of Fe2C, Cr3C2, and CuNi. In addition, at higher values of discharge current and ton/toff ratio, the micro-cracks propagate on the surface of the workpiece.

Published: June 2021

Natural gas is a mixture that is widely used in the industries. Knowledge of its thermodynamic properties is essential for evaluating the process and equipment performance. This paper quantifies the energy that can be extracted from natural gas using a turbo expander. Natural gases of wide-ranging compositions collected from 6 different gas fields in Egypt were investigated based on energy and exergy analysis. The study was conducted using MATLAB. Numerous simulation runs were made by taking various typical feed compositions classified as lean and rich. The effects of increasing the amount of C1, C5 in the feed stream on the efficiency of energy utilization are presented. A validation analysis was performed. The results show similar trends and good agreements. It was concluded from the results that when the concentration of methane in the gas mixture increase, the exergetic efficiency decreases. The results also show that the values of thermodynamic properties depend on the relative amount of heavy components in the feed stream.

Published: June 2021

The objectives of this study were to: (i) determine the effects of tryptophan on the polymorphic phase transformation of CaCO3, (ii) investigate the thermal degradation characteristics of CaCO3 in terms of kinetics and thermodynamics using the Coats–Redfern method, and (iii) assess the influence of the experimental conditions on the vaterite composition of CaCO3 using response surface methodology based on central composite design. First, the CaCO3 crystals were prepared and analyzed using XRD, FTIR, SEM, BET, AFM, and zeta potential analysis. Based on the characterization results, the shape of the CaCO3 crystals changed from smooth cubic calcite crystals to porous irregular spherical-like vaterite crystals with increasing tryptophan concentration. Meanwhile, the kinetic results showed that the thermal degradation of CaCO3 followed the shrinkage geometrical spherical mechanism, R3 and the average activation energy was 224.6 kJ/mol. According to the results of the experimental design, the tryptophan concentration was the most influential variable affecting the relative fraction of vaterite in the produced crystals. It can be concluded that tryptophan is important for better understanding and controlling the polymorph, size, and morphology of CaCO3 crystals.

Authors: Samsudin Achmad
Published: June 2021

Penelitian ini bertujuan untuk melihat pengaruh “ASSAF” (Assessment Animation Format) terhadap hasil tes pemahaman konsep siswa di salah satu SMP Negeri di Kota Bandung pada materi Cahaya. Kajian difokuskan pada hasil tes pemahaman konsep cahaya dan kuantitas miskonsepsi siswa terhadap penggunaan butir soal “ASSAF”. Data untuk menarik kesimpulan hasil penelitian, dikumpulkan melalui pemberian tes pemahaman konsep siswa yang dilakukan sesudah pelaksanaan pembelajaran. Untuk mencapai tujuan penelitian tersebut digunakan metode penelitian kuasi eksperimen dengan desain penelitian Randomized posttest-only control group. Subjek penelitian ini melibatkan dua kelompok yaitu kelompok kontrol berupa paper and pencil test dan kelompok eksperimen berupa “ASSAF”. Data pemahaman konsep yang akan diperoleh dari kedua kelompok tersebut dicari rata-ratanya dan diolah dengan menggunakan Uji Hipotesis nonparametrik (Uji Wilcoxon). Setelah dilakukan uji perbedaan melalui uji wilcoxon didapatkan bahwa nilai Z hitung lebih besar daripada nilai Z tabel. Hal ini menunjukkan bahwa hipotesis alternatif pertama (H1: memk) diterima, sekaligus memiliki pengertian bahwa hasil tes pemahaman konsep kelas eksperimen lebih baik secara signifikan dibandingkan kelas kontrol. Selain itu diperoleh data bahwa persentase rata-rata posttest pemahaman konsep untuk kelas eksperimen sebesar 67,96 % dan persentase rata-rata posttest pemahaman konsep untuk kelas kontrol sebesar 44,62%.
