Rituell unmusikalisch? Resonanzen in psychoanalytischen und theologischen Kontexten
Authors: Odenthal Andreas
Published: June 2021

Ausgehend vom Freud’schen Garnrollenspiel werden Rituale als eine Möglichkeit des Kindes gedeutet, mit der frühen Verlusterfahrung der Mutter kreativ umzugehen und den Freiraum des eigenen Lebens zu entdecken. Anknüpfend an Donald W. Winnicott kann der kulturelle Bereich insgesamt als ein dritter Wirklichkeitsbereich verstanden werden, in dem der Doppelwunsch nach Schutz und Trost einerseits sowie nach Aufbruch und Selbstwerdung andererseits seinen Ausdruck findet. Dieses Konzept wird mit der theologischen Definition des Gottesdienstes als „Feier des Pascha-Mysterium“ vermittelt: Das Volk Israel vergewissert sich im Pascha-Mahl des Schutzes seines Gottes und kann den Schritt in die Befreiung aus der Sklaverei Ägyptens tun. Jesus versichert sich beim Letzten Abendmahl des Schutzes seines Gottes und kann den entscheidenden Schritt in sein Leiden, Sterben und Auferstehen tun, was für die glaubenden Menschen als das befreiende Heilsereignis angesehen wird. Der Resonanzraum Gottesdienst verbindet so Lebensgeschichte und Heilsgeschichte (rituelle Erfahrung). Der interdisziplinäre Dialog von Psychoanalyse und Theologie ermöglicht so tiefe Einsichten in die Bedeutung des Rituellen für die Menschen.

I. The Threefold Summons at Late Antique Church Councils
Authors: Constantinou Maria
Published: June 2021

The threefold summons of an absent defendant in the context of synodal proceedings – which had been admittedly formed by influence from the respective process in Roman law – is an important component of the ecclesiastical judicial procedure. In this paper I examine in detail all the extensive narratives of threefold summonses preserved in conciliar acts of the fifth and sixth centuries, that is, the cases of Nestorius of Constantinople and John of Antioch at the council of Ephesus (431), the case of the archimandrite Eutyches at the Resident Synod of Constantinople (448), the case of Athanasius of Perrhe at the local synods of Hierapolis (early 440s) and Antioch (445) as well as at the Council of Chalcedon (451), the case of Dioscorus of Alexandria at the Council of Chalcedon, and the case of Anthimus of Constantinople at the Resident Synod of Constantinople (536). In the final part I proceed to an assessment of this process’ evolution over the period in question. The principal conclusion is that by the time of Justinian the ecclesiastical threefold summons procedure had become consolidated and systematised.
V. Leges fundamentales: Gesetze, die gleicher sind als andere? Vom Inhalt zum Begriff
Authors: Schmoeckel Mathias
Published: June 2021

Leges fundamentals: Laws Higher than Others? Their Development from the Concept to the Term. This article investigates the tradition of laws with a higher, central authority, which can be found in the Christian tradition from the Middle Ages to the 16th century, when the Calvinist party finally coined the term “loi fondamentale”. The contrast to other national discussions shows the different starting points and contents of a notion, which rapidly became a common European heritage and merged with the equally new concept of “constitution”.

An essay on the occasion of his death 500 years ago. The essay deals with the professor of Canon Law Henning Goeden at the Central German universities Erfurt (founded 1392) and Wittenberg (founded 1502). It contains important facts of Goeden’s academic biography, of his scientific and practical work (consilia), his church offices and his relationship to the Lutheran reformation. The practice of teaching of Canon Law within the system of lections at the Wittenberg Law Faculty under the conditions of the reformation and the increasing influence of Protestant Ecclesiastical Law is considered too.
VIII. Ohne Körperschaftsgarantie keine Reichsverfassung?
Authors: Janssen Achim
Published: June 2021

No Weimar Constitution without a guarantee of the corporate status of religious communities? The discussion about article 137 section 5 of the Weimar Constitution and its content in the National Assembly of Weimar. Some researchers hold that without the constitutional guarantee of the corporate status of religious communities in article 137 section 5 the Weimar Constitution in 1919 would not have come about. The minutes of the constituent Weimar National Assembly, however, do not indicate that the guarantee of the corporate status was in danger to fail in default of political consensus. Rather, the decision in favour of a constitutional guarantee of the corporate status had already been made early in the debate. Yet it remained unclear and controversial which rights this status contained, except of the right to taxation explicitly guaranteed by article 137 section 6 of the Weimar Constitution. The deputies assumed that the specific rights of the religious communities were not determined by Article 137 section 5 of the Weimar Constitution, but by the legislation of the German Länder.

The study aims to answer the question concerning how effectively cities of the Siklós district can involve the surrounding settlements in the tourism economy, thereby promoting the development of rural areas. In addition to local governments and tourism organizations, our important goal is to understand the ideas of service providers and their guests related to rural development, as well as the space use characteristics of the latter group. The key method is the questionnaire survey, the target group of which is the mayors of all settlements in the district, as well as the guests of the accommodations belonging to the different product types. The primary sources are based on two further series of interviews, which explore the opinions of service providers and professional organizations. Empirical experience shows that thematic trips can play a prominent role in the development of the less frequented small settlements. The essence of this is to connect the places offering traditional crafts and local products by a bike route.
Critical Properties and Acentric Factors of Pure Compounds Modelling Based on QSPR-SVM with Dragonfly Algorithm
Authors: Moussaoui Mohammed , Hentabli Mohamed , Abdallah Abdallah El Hadj , Hanini Salah , Laidi Maamar
Published: June 2021

This work aimed to model the critical pressure, temperature, volume properties, and acentric factors of 6700 pure compounds based on five relevant descriptors and two thermodynamic properties. To that end, four methods were used, namely, multi-linear regression (MLR), artificial neural networks (ANNs), support vector machines (SVMs) using sequential minimal optimisation (SMO), and hybrid SVM with Dragonfly optimisation algorithm (SVM-DA) to model each property. The results suggested that hybrid SVM-DA had better prediction performance compared to the other models in terms of average absolute relative deviation (AARD%) of {0.7551, 1.962, 1.929, and 2.173} and R2 of {0.9699, 0.9673, 0.9856, and 0.9766} for critical temperature, critical pressure, critical volume, and acentric factor, respectively. The developed models can be used to estimate the property of newly designed compounds only from their molecular structure.
Myxedema coma complicated by bilateral hygromas
Authors: Meling Stokland Ann-Elin , Dahle Anne Lise , Kloster Vidar Laurits , Nedrebø Torbjørn , Nedrebø Bjørn Gunnar
Published: June 2021

Myxedema coma is an important differential diagnosis in critically ill patients. Early diagnosis and treatment are paramount but challenging due to a lack of diagnostic criteria. We report a case about a patient who suffered from untreated hypothyroidism for several years. Before the correct diagnosis was made, he was admitted three times due to severe constipation. Eventually, he developed myxedema coma in connection with a urinary tract infection. The course was complicated by recurrent seizures, and neuroimaging showed bilateral hygromas. Hormone replacement therapy resulted in complete recovery and regression of hygromas. To the best of our knowledge, this is the first time hygroma is reported in association with myxedema coma.

Learning points

Myxedema coma is a difficult diagnosis to make due to a lack of diagnostic criteria.

Cardinal features include hypothermia, bradycardia, gastrointestinal symptoms, pericardial/pleural effusions and affection of CNS. Anemia and hyponatremia are common.

In case of suspected myxedema coma, neuroimaging should be a part of the evaluation in most cases.

There is a possible association between longstanding/severe hypothyroidism and hygroma.
Reducing COVID-19 Infection Risks in Retail Stores through Mobile Payments: Investigating the Determinants of In-Store Proximity M-Payment Usage
Authors: Wagner Gerhard , Steinmann Sascha , Hälsig Frank , Schramm-Klein Hanna
Published: June 2021

During the global coronavirus disease 2019 (COVID-19) pandemic, the relevance of proximity mobile payment (m-payment) applications (e. g., Apple Pay and Google Pay) has increased due to their ability to let consumers shop inside physical stores and pay for products without having to make physical contact with a store employee or touch a card-reader terminal. Despite the growing usage of mobile applications for a number of everyday tasks, in recent years, the diffusion of in-store proximity m-payment in many countries is still low, and the actual usage is sparse. To understand which factors can motivate consumers to use proximity m-payment services in retail stores, this study combines the individual disposition to adopt and use in-store m-payment technologies with system-based evaluations. By applying a conceptual model to a representative sample (N = 3,250) of grocery store shoppers, the results provide evidence of a general effect of technology readiness on consumers’ behavioural intention to use in-store m-payment.
How Online Trust and Online Brand Equity Translate Online- and Omni-Channel-Specific Instruments into Repurchase Intentions
Authors: Swoboda Bernhard , Winters Amelie , Fränzel Nils
Published: June 2021

This study examines omni-channel retailers’ online activities, which previous brick-and-mortar firms’ find challenging, but they are increasingly competing with online players. Therefore, the role of major online-specific instruments such as online aesthetic appeal and omni-channel-specific instruments such as online-offline integration is studied. A framework is proposed in which online trust, as a key mediator in online studies, translates instruments into repurchase intentions. However, the authors also study online brand equity, believing in its strength for repurchasing in competing, reciprocal mediation. They test indirect effects of the instruments in a sequential mediation study and reciprocal effects of trust and brand equity in a cross-lagged panel study based on longitudinal data of consumer evaluations of fashion retailers. Importantly, cross-channel repurchase intention is differentiated. The results provide new empirical evidence of a different relative importance of the instruments and of online trust versus online brand equity. The findings have direct implications for managers interested in understanding which instruments most affect consumer outcomes.
The Internationalization of German Marketing Science
Authors: Simon Hermann
Published: June 2021

In the 1970s, marketing science in Germany was limited to the German-speaking world. My early appeal to publish in English and to change the language of German journals to English met with strong opposition from established professors. Today, 40 years later, a considerable number of German-speaking marketing scientists belong to the international top group in the Hirsch-index ranking. German journals are now publishing in English, but the transition came late, and it will be difficult to acquire A-journal status. In terms of inbound internationalization a lot remains to be done.

Determination of the suitable shape for tensile tests parallel to the fibers in Guadua angustifolia Kunth specimens
Authors: Acosta Ricardo , Montoya Jorge A. , Welling Johannes
Published: June 2021

The tension test parallel-to-fiber in anisotropic materials, such as bamboo, is one of the most important tests because it makes it possible to evaluate mechanical properties used in calculations for different types of stresses. For this type of test there are standards that apply to wood in general, others to bamboo, and other more specific ones that apply to bamboo Guadua angustifolia Kunth. These rules suggest the use of dog bone test specimens. When performing such tests parallel to the fiber direction, failures are observed in undesired zones. This document characterizes and analyzes the possible types of failures. It also evidences the difficulties presented and quantifies them finding that, for 59 failed test pieces, only 18.6% had failures within the desired zones, while the other 81.4% had failures within undesired zones in the tension test parallel to the fiber. Finally, it can be concluded that there are gaps in the rules that influence the variation of the results obtained by different authors. The dog bone test specimens are not recommended for tension tests parallel to the Guadua fiber. Rather, utilization of straight specimens is recommended with a calculated clamping height and the standard equation and protected clamping area.
Surface physical structure and durability of superhydrophobic wood surface with epoxy resin
Authors: Kang Fan , Yi Zede , Zhao Bo , Qin Zhiyong
Published: June 2021

In this study, a superhydrophobic wood surface was prepared with amino-functionalized nano-silica (SiO2) particles, epoxy resin (EP) of different curing times, and octadecyltrichlorosilane (OTS). The micro-nano structures of the wood samples were represented by scanning electron microscopy (SEM), while the hydrophobicity and durability of the hydrophobic effect was shown by the contact angle (CA) tests. The results indicated that the optimal curing time of EP was 4 h, such that the wood surface exhibited promising superhydrophobicity with a static CA of 155.4° and a sliding angle (SA) of 3.9°. The different curing time of EP had a remarkable influence on the roughness and the pore structure type of superhydrophobic wood surface. In terms of the Cassie-Baxter theory, the increase of CA on the wood surface was ascribed to the presence of secondary air pores and rough structure in the solid-liquid interface. The obtained wood surface not only possessed excellent adhesion stability and anti-aging properties, but also a resistance to acidic solutions, organic solvents, and mechanical abrasion.

Published: June 2021

Water safety and security has become a great problem in recent years, as the shortage of water resources in most countries is becoming an increasingly serious issue. Therefore, searching for new water sources or treating contaminated water has become a major requirement to covering the shortage of fresh water. The current study evaluated the impact of Trichoderma asperellum on the physicochemical characterization of agricultural run-off (AR) compared with groundwater (GW). Chemical oxygen demand (COD), biological oxygen demand (BOD5), ammonia, total nitrogen (TN), and total dissolved salts (TDS) of AR were higher than that of GW with 90, 90.2, 91.9, 78, and 61.6%, respectively. The addition of T. asperellum to AR caused the COD, BOD5, ammonia, TN, and TDS to decrease 47.2, 39.2, 16.2, 12.9, and 4.8%, respectively. Contents of metals in AR or GW were decreased by T. asperellum. Microbial analysis of soil irrigated by AR in contrast to irrigated by GW showed the presence of a high number of bacteria (32 × 106 CFU), actinomycetes (18 × 104 CFU), and fungi (13 × 104 CFU). Trifolium alexandrinum growth and its antioxidant enzymes activities (catalase, superoxide dismutase, and ascorbate peroxidase) were enhanced by AR inoculated by T. asperellum compared with un-inoculated AR or GW.
Characterization and usage of tule (Typha domingensis Pers) to obtain cellulose pulp in a biorefinery framework
Authors: Loiaza Javier M. , Zamudio Minerva A. , Lozano Susana , Alfaro Ascension , Garcia Maria T. , García Juan C. , Lopez Francisco
Published: June 2021

It was proposed that pre-hydrolysing tule (Typha domingensis Pers) would make it possible to produce handsheets with strength-related properties similar to those of conventional commercial paper, in addition to valorizable hemicelluloses. The hypothesis was tested with a biorefining scheme involving autohydrolysis. Conditions were optimized to maximize the extraction of hemicelluloses while preserving glucan integrity. The autohydrolysis at a liquid to solid ratio of 13 at 141 °C for 45 min (optimized conditions) provided a commercially useful liquor containing primarily tule hemicelluloses. The autohydrolysis of tule before alkaline extraction made it possible to obtain a valuable liquid phase comprising between 23.3% and 71.6% of all hemicelluloses in the raw material. The gross heating value for the hydrolyzed tule was increased (1.6% to 7.9 %) with respect the raw material. The solid phase was subjected to soda–anthraquinone pulping. The yield, ethanol extractives, kappa number, viscosity, glucan, xylan, Klason lignin, soluble lignins, as well as the tensile index were evaluated. Tule was found to be amenable to industrial processing for the production of quality cellulose derivatives. Autohydrolysis provided valorizable liquor in addition to solid that yielded soda–anthraquinone pulp having properties similar to those obtained in its absence, but using milder operating conditions.
Investigation of the Thermal Strength of Steam Turbine Diaphragms with Reduction of Axial Dimensions

Published: June 2021

The problem of reducing the axial dimensions of steam turbine diaphragms is associated with the problem of steam turbine modernization performed by increasing the number of reactive blading stages and using existing foundations. Evaluation of the suitability of diaphragm design versions with established steam flow characteristics was carried out with constraints on short- and long-term strength conditions, as well as the accumulation of axial deflections due to creep. For computational research, there was introduced a methodology using the finite element method and Yu. M. Rabotnov’s theory of strain aging. The calculation of creep was reduced to solving an elastic-plastic problem with a deformation curve, which was represented by an isochronous creep curve for the time chosen. A software was used providing for the automated construction of the original computer diaphragm model with the help of guide-vane profile drawings and axial cross-sections of the diaphragm rim and body, as well as several geometric parameters. The calculated model of a welded diaphragm reproduces the main essential features of the structure, the material properties of its elements, as well as steam load. The exploratory studies of diaphragms with reduced axial dimensions were performed on the example of the second- and third-stage diaphragms of the high-pressure cylinder of the K-325-23.5 steam turbine. The original second- and third-stage diaphragm designs were considered to be basic, in relation to which, according to strength and rigidity parameters, the alternative ones were compared. Calculated data for the basic diaphragm design versions for 100 thousand operating hours were obtained. According to the calculations, maximum deflections are achieved at diaphragm edges, and the stresses, that are maximum at the points where the guide vanes are attached to the diaphragm rim and body, undergo a significant redistribution due to creep. Two approaches to the reduction of the axial dimensions of the second-stage diaphragm design of the steam turbine high pressure cylinder were involved. In the first approach, the reduction of the dimensions was achieved by proportionally reducing the guide-vane profile with a corresponding increase in the number of the guide vanes. In the second approach, the profile remained unchanged, but the axial dimensions of the diaphragm rim and body were reduced. The parameters of strength both in the elastic state at the beginning of operation and in the conditions of creep, as well as the accumulation of axial deflections were investigated. Based on the comparisons with the basic design, it was established that the second approach is more effective. Additional recommendations for the use of more heat-resistant steels for outlet guide vanes and the conditions of diaphragm attachment in the turbine casing are given.
An Adaptive Method for Numerical Differentiation of Difficult-to-Compute Functions

Published: June 2021

An adaptive approach to the numerical differentiation of difficult-to-compute functions is considered. Complex dependencies, which are the result of multiple superpositions of functions or the product of various algorithmic processes, are knowingly difficult to study directly. To establish the nature of the behavior of such dependencies, one has to resort to numerical analysis. One of the important characteristics of functions is a derivative, which indicates the direction and rate of change of a dependence. However, with difficult-to-compute functions, the available a priori information is not always sufficient to achieve the appropriate accuracy of the solution by known means. The loss of accuracy occurs due to the accumulation of round-off errors that grow in proportion to the number of calculated values of a function. In this case, it is necessary to pass on to the posterior approach in order to determine the behavior of the function and move away from the scheme of equidistant nodes, relying on an adaptive way of studying the local situation in the domain of the function. This paper implements an adaptive method for finding derivatives of a function with a minimum of restrictive requirements for the class of functions and the form of their assignment. Due to this, the costs of calculating the function have been significantly reduced with the result that their number has been brought to almost the optimal level. At the same time, the amount of RAM used has sharply decreased. There is no need for a preliminary analysis of the problem of establishing the class of the function under study, in the involvement of special functions or transformation of initial conditions for using standard tables of weight coefficients, etc. For research, it is enough to assign a continuous and bounded function on a fixed segment and a minimum step, which is indirectly responsible for ensuring the required accuracy of differentiation. The effectiveness of the proposed method is demonstrated on a number of test examples. The developed method can be used in more complex problems, for example, in solving some types of differential and integral equations, as well as for a wide range of optimization problems in a wide variety of areas of applied analysis and synthesis.

A presente pesquisa, apresentada neste artigo, teve como objetivo identificar em que medida os contos clássicos da literatura infantil universal ainda circulam nas bibliotecas escolares, após a implantação do Plano Nacional Biblioteca nas Escolas (PNBE), e como essas histórias têm repercutido na contemporaneidade, em relação aos pequenos leitores. O eixo metodológico do estudo foi constituído a partir de uma análise bibliográfica, de natureza qualitativa e descritiva, e também de uma pesquisa de campo, feita com uma funcionária que atua como bibliotecária e alunos do 3° ano do Ensino Fundamental, em uma escola situada na região sul do estado de Mato Grosso do Sul. Os dados foram analisados com bases teóricas da literatura especializada na temática, e os resultados obtidos apontam que há um grande interesse das crianças por essas histórias, porém, os filmes que se remetem a tais narrativas têm chamado mais atenção dos leitores do que os livros em si. Em relação aos contos clássicos, é possível notar que, com as mudanças do mercado editorial e implantação do PNBE, as escolas receberam apenas releituras dessas obras, indicando uma tendência de esquecimento do conto clássico, no que se refere à publicação em formato de livro.

We investigated the cases with Aeromonas bacteremia in terms of clinical and microbiological characteristics, underlying disease and mortality rates. Patients with positive blood cultures were included in this research. Aeromonas bacteremia was diagnosed as at least one positive blood culture for Aeromonas species. The bacteremia was defined as community origin if the onset was in the community or within 72 hours of hospital admission. The others were considered as nosocomial. All bacteria were defined as Aeromonas with conventional method. Species identification was verified by VITEK system. Antibiotic susceptibility tests were analyzed with the disc diffusion, E-test method or VITEK system. Thirty-three patients were diagnosed with bacteremia due to Aeromonas spp. Hematologic and solid tumors were the leading underlying conditions, followed by cirrhosis. Two patients (6%) had community-acquired infections. Aeromonas hydrophila was the most common isolated bacterium. The crude mortality rate was 36%. 12 patients died and 6 deaths and 4 deaths were detected in patients with bacteremia caused by A. hydrophila and Aeromonas sobria respectively. All strains were resistant to ampicillin and more than 90% of the strains were susceptible to trimethoprim-sulfamethoxazole, fluoroquinolone, third generation cephalosporins, and carbapenems. Aeromonas sp. is not a frequent cause of bacteremia however, it may lead to high mortality rates, especially in the immunocompromised hosts and patients with liver cirrhosis. Nosocomial Aeromonas bacteremia is not uncommon in these populations. Broad-spectrum cephalosporins, piperacillin-tazobactam, fluoroquinolones, and carbapenems remain as effective antimicrobial agents for therapy of Aeromonas bacteremia.
The life and works of Domenico Mario Nuti, 1937–2020: An appreciation
Authors: Estrin Saul , Uvalic Milica
Published: June 2021

It is challenging to provide an encompassing portrait of Mario Nuti's life and works: he was an exceptional man, who made significant intellectual contributions across a wide range of fields, as well as inspiring generations of students, colleagues and the profession in general, for more than fifty years. A brilliant debater and controversialist, he was equally at home in economic theory and in giving policy advice, and over the decades he had made significant contributions to many branches of the discipline. In this memorial article, we try to give a flavour of the man and his work, hopefully reminding the conoscenti of Mario's perceptive and original work, while introducing a new generation of scholars to his distinctive take on the field of economics.
Correlation between misinvoicing and non-tariff measures for Turkey's exports to the EU
Authors: Karataş Ayşegül , Şimdi Halil , Garip Büşra
Published: June 2021

Many researchers have analysed the factors that cause discrepancies in the mirror trade statistics. However, the conflicting findings of the relatively limited number of studies on the relation between non-tariff measures and misinvoicing make further research in this area necessary. Therefore, our paper aimed to analyse the impact of non-tariff measures on misinvoicing in the context of Turkey's exports to the European Union (EU) between 2008 and 2015. This study tested the possible relationship between them using other measurable variables related to Turkey's exports to the EU of the products to which the non-tariff measures were applied. This has been done by employing the dynamic generalized method of moments (GMM) as well as the quantile regression (QR) models. It was observed that tariffs, along with non-tariff measures, have negative relationship with the misinvoiced amount. Additionally, it is also observed that the transfer price manipulation appears to be a means of corporate tax evasion. This finding aligns with the decrease in reported imports and the decrease in the perceived levels of corruption.

Published: June 2021

Among historical sites in Kudus, Central Java is Langgar Bubrah, in which laying lingga and yoni, two symbols often found in a Hindu temple. Some archeologists consider this as proof of Sunan Kudus’s tolerance. This paper analyzes the preservation of religious sites and their relation to promote religious tolerance. Data were collected through interviews, observation, and documentation analysis is descriptive qualitative. The result shows that Sunan Kudus promoted tolerance among his people by preserving several old traditions such as preventing. However, the Kudus Regency Government has optimized tried to treat it, so it needs to be scheduled to rescue cultural objects, namely restoration, revitalization, and facilitating cultural facilities and infrastructure in the form of performance spaces. Kudus local parliament members also need to realize the budget politics in the regional budget, which favors cultural preservation by providing funding for cultural advancement based on investment considerations. The research to contribution for development archeology associated with culture heritage Hindu in Kudus pra-Islam.

The article summarizes the data on the initial stage of metal production in the Southern Urals of the Bronze Age. Lots of Yamnaya culture burial mounds with copper items inside were excavated near the Kargaly deposit in the Orenburg oblast. The variety and originality of tools forms indicate the independent nature of the Ural metallurgy in the early Bronze Age. The authors present new data that allows us to reconstruct the process of metal production at the Repin (early) stage of the Yamnaya culture and explain the beginning of this process by the development of the Kargaly copper ore deposit. Excavations of the Turganik settlement were carried out. Cultural layer 5 of the early Bronze Age is dated to 3800–3360 cal BC. It is characterized by ceramics and other artefacts of the Repin type. Fragments of Kargaly copper ore, slags and copper tools (knife, awls) were found in the layer. The traceological analysis of about approximately 100 items made of stone and animal bones was performed. 41 of them are related to metallurgy and metalworking. They represent tools of all metallurgical production stages, starting from metal extraction from ore to the processing of the finished copper product. Functional groups of products such as ore mortar, ore crushing hammers, casting molds, forging hammers, anvils, edges leveling tools, sharpening stones, and others have been identified. Stone artifacts from the burials were also studied, including ore crushing and forging hammers. No mining tools were found at the settlement. It is concluded that the ore was extracted and processed at the Kargaly deposit, located 70 km to the east, and then delivered to the settlement as an enriched concentrate. The settlement was seasonal. Metallurgical activity here took its place in the summer, since the main type of economic activity was nomadic pastoralism.

The article considers the currently known bronze flat petiolate arrowheads with stings found in the steppe and forest-steppe zones of the Northern Black Sea region, along with new finds. In total, 19 petiolate arrowheads with stings and 3 negatives of similar products on casting molds were taken into account. The distribution area of such items covers the entire western part of the region, between Danube-Carpathian region and the Dnieper basin. The finds are concentrated in the southern part of the Middle Dnieper region (9 items), the North-West Black Sea region (5 items), and the Upper Dniester region (3 items). One arrowhead was found in Podolia and another one was discovered in Northern Bukovina. All currently known casting molds for manufacturing petiolate arrowheads stings come from the North-Western Black Sea region, which allows to localize there one of manufacturing centers. Based on the design features of petiolate, it is proposed to divide all flat petiolate arrowheads with stings into five types. In addition, it is considered the possibility of selecting sub-variants if necessary: by the width of the feather, by the length of the petiole, by the presence of rib in the middle of the feather, by the asymmetry of the stings, by massiveness, etc. Arrowheads of the discussed type, with their archaeological context being reliably known (Magala, Novoselitsa, Volkovka, Gordeevka, Petrikov, Stary Buyukany), are associated with closed complexes of the BrD – HaB1 period (XIII–X centuries BC) in the North Black Sea region. All occasional finds from the region can be dated within these limits. The arrival of bronze petiolate arrowheads with stings in the Northern Black Sea region may have been influenced by contacts with the Balkan-Carpathian and Middle Eastern cultural centers. It cannot be ruled out that the regional manufacturing of such arrowheads could be based on imitating local flint implements of the same type, found in various Bronze Age cultures.
New Pre-Scythian Burials from the Volgograd Region. Interpretation Problems
Authors:   Volgograd State University, Dyachenko Alexandr
Published: June 2021

The article is devoted to the publication and analysis of new burial materials of the pre-Scythian period (9th – 7th centuries BC), obtained as a result of excavations of several burial mounds in the Volgograd region. The work was carried out by the expedition of Volgograd State University from the end of the past to the beginning of the present century. The burial mounds were located on the coastal terraces of the Don river and some of its tributaries, as well as on the steppe watersheds associated with the Don basin. The sample includes seven pre-Scythian burials, the burial rite and clothing material of which allows us to correlate them with the previously discovered monuments of the Chernogorovskaya Culture of the southern Russian steppes and date them within the boundaries of the initial stage of the early Iron Age. According to archaeological and anthropological data, various components were involved in the formation of this culture in the Lower Volga region and the neighbouring Don and the Volga-Ural regions. The basis was autochthonous substrates of the Late Bronze Age, as well as cultural formations derived from them at the final stage of the Late Bronze Age. The combination of local and imported cultural traditions is also reflected in the grave inventory of the studied series, especially in the ceramic complex, which shows technological and typological features of various origin. The variety of elements of the funeral rite and the mixed nature of the accompanying inventory of the presented burial series reflect the complex processes of cultural genesis in the Lower Volga region in the pre-Scythian period during transition to a nomadic economy.
Antimalarial phytochemicals as inhibitors against COVID-19 ACE2 receptor: Computational screening

Published: June 2021

Quinine, artemisinin, febrifugine, brusatol, chaparrin tehranolide, glaucarubin, sergeoliden, and yingzhaosu A, nine antimalarial phytochemicals, were the focus of an in-silico analysis aimed at discovering new therapeutic molecules against COVID-19 infection. The screening of these molecules included a molecular docking approach within the Angiotensin-converting enzyme-2 (ACE2) receptor. In addition, drug-likeness, ADMET analysis and pharmacophore mapping have been performed. The result of the docking process was based on the energy binding values as well as the number and type of interactions established with the receptor active site residues, which were compared with those of co-crystallized ligand and chloroquine. Febrifugine showed the most interesting energetic and interactive activities that were closer to the reference molecule and better than those of chloroquine. Whereas artemisinin has produced results that are the closest to those of chloroquine. Similarly, drug-likeness and ADMET analysis have shown that febrifugine and artemisinin check most of the filters and pharmacokinetic properties required for the choice of an effective therapeutic molecule. A pharmacophore model was designed on the basis of a training set consisting of the most relevant molecules; it has one metal ligator cum hydrophobic region cum hydrogen bond acceptor, one hydrogen bond acceptor cum metal ligator and one hydrophobic aromatic ring. This model is proposed to be used for the in-silico discovery of new therapeutic molecules against coronavirus.

Cutaneous leishmaniasis is a common anthropozoonosis and a major public health problem in Algeria. Therefore, we conducted an ethnopharmacological survey in the locality of Ain Sekhouna (located in the highlands of western Algeria), one of the foci of cutaneous leishmaniasis. We aimed to identify the medicinal plants and natural remedies used by the local population to treatment cutaneous leishmaniasis. We identified three plant species, belonging to three distinct families, used as natural remedies against the disease, namely, Haloxylon scoparium Pomel (Chenopodiaceae, 73%), Artemisia herba-alba Asso. (Asteraceae, 18%), and Camellia sinensis L. (Theaceae, 9%). Additionally, 35% of the plant-based medicines mostly comprised the powdered form of the aerial parts of the plant. According to the respondents, the powder is combined with butter, cade oil, or honey and is applied exogenously on the skin. Overall, these medicinal plants can be used as a source of natural medicines, in combination with commonly used dermatological excipients, to treat cutaneous leishmaniasis.
