CHEMICAL COMPOSITION OF THE METAL WARE FOUND IN THE LATE SCYTHIAN CEMETERY OF LEVADKI
Authors: Antipenko Anna , Mul’d Sergey
Published: April 2024

This article addresses the study of the chemical alloy composition of the artefacts made of non-ferrous and precious metals and discovered in the cemetery of Levadki in Central Crimea. The elemental composition of the finds was studied with non-destructive standardless X-ray fluorescence at the Storage Department of the Central Museum of the Taurida. The research used a sample of 68 artefacts and their components discovered in 23 burial structures dated from the Late Hellenistic and Roman Periods. From the formula of the main alloy components, the sample under study comprises: 17.65% of “pure” copper, 8.82% of brass, 11.76% of multicomponent zinc-containing alloys, 1.47% of lead bronze, 19.12% of tin bronze, 38.24% of tin-lead and lead-tin bronze, 1.47% of lead, and 1.47% of silver. The analysis of alloy composition by categories of grave goods has revealed that tin and zinc were the main alloying species in brooch production. The belt and sword-belt parts were made of alloys featuring various formulae, ranging from “pure” copper to three-component bronze variants. The research on ornaments and accessories has uncovered that this group includes the artefacts of “pure” copper along with the pieces alloyed with tin and lead, with the latter component comprising from one-third to a half of the composition, particularly in cast ornaments. This group divides into at least three subgroups, differentiated by the technique applied in the making of the artefacts and the composition of the alloy. Weaponry items are represented by the arrowheads. There are three cases of the arrowheads made of lead-tin bronze and one case more of “pure” copper.
BRACELETS WITH WIDENED ENDS MADE FROM PRECIOUS METALS OF THE LATE ROMAN AND THE GREAT MIGRATION PERIOD: DANUBE-DNIEPER-BALTIC PARALLELS
Authors: Khomiakova Olga
Published: April 2024

By the 5th century AD, massive gold bracelets with widened ends had become prestigious cultural elements, symbolizing the power of the barbarian tribal groups’ rulers. The areas where such finds were discovered are located primarily in the Carpathian-Danube region and Gallia. Under the influence of this fashion for displaying high social status, bracelets with thickened ends made from silver, the material available to the tribes in the western part of the East European Plain, became widespread in the 5th century. There are two zones of their concentration: the northern zone in the Baltics, Upper Dnieper region, and Middle Oka region; and the southern zone in the Middle Dnieper region and the left-bank forest steppe of the Dnieper. Bracelets made from silver and its alloys from the Middle Dnieper region were found in women’s burials and hoards, indicating their connection with female outfits. Their appearance could be associated with the influence of the “Middle Danube” model of female outfit during the Great Migration period, and this model persisted up until the 6th – 7th centuries. The second group of bracelets is documented in the antiquities of Nemunas and the Western Dvina basins in the Baltics. They are predominantly found in male warrior complexes dating back to the 5th century, belonging to the members of goroups involved in strategic control over important routes connecting Scandinavia and Southeastern Baltic with the eastward territories.
ETHNOCULTURAL SITUATION ON THE TERRITORY OF THE UPPER OKA IN THE “PRE-ROMEN” PERIOD (LATE 7TH TO 8TH CENTURIES)
Authors: Kolokolov Aleksandr
Published: April 2024

The study is devoted to the identification of a group of antiquities of the late 7th – 8th centuries of the Upper Oka region. On the territory of the region, the sites of the Moshchin culture, which had existed from the middle of the 3rd century, practically disappeared around the middle of the 7th century. The end of the Late Dyakovo culture in the Moscow basin and the disappearance of the main part of the Ryazan-Oksk sites in the Middle Oka region belong to the same time. Since the 9th century, numerous sites correlating with the antiquities of the Romensk culture have appeared in the territory of the region. The ethnocultural situation of the Upper Oka in the “pre-romensky” period has not been clearly presented until recently. To date, an array of archaeological material has been accumulated that is characteristic of the period. It is represented by finds of ceramic vessels, jewelry and belt details from the hill forts of Supruty, Petrovskoe, Nikulino, Muravlevo, as well as from the settlements of Kamenka-1, B. Triznovo-3, Torhovo-3, Utkino-1. Based on the analysis of the finds, it can be assumed that the main population of the Upper Oka region in the period of the 2nd half of the 7th – 8th centuries was the bearers of sakhnovka-volyntsevo type antiquities. Finds of vessels of the Moshchin tradition in the complexes of the 9th – 10th centuries of the Supruty ancient hillfort and the Kamenka-1 settlement testify to the existence in the pre-romensky and romensky periods of the remnants of the population that lived in the region from the middle of the 3rd to the middle of the 7th centuries. The study of a unique memorial complex near the village of Gora Uslan allows us to assume participation in the formation of the ethnocultural situation in the Upper Oka region in the late 7th – 8th centuries of the steppe of cultures representatives of the early Khazar Kaganate era.
THIRD CENTURY AD BURIAL VAULTS FROM THE CEMETERY OF OPUSHKI
Authors: Khrapunov Igor
Published: April 2024

There was some important event taking place in the Crimea in the third century AD or a little bit earlier that was probably reflected by the appearance of burial vaults of a special design that had not been previously known in Crimea. These vaults comprised an entrance pit and a burial chamber with a short (0.4–0.8 m long) underground corridor (dromos) dug in between them; the funerals in the burial chamber were made on the floor in one tier. Until recently, only a few short-dromos burial vaults from the third century AD were known in the Crimea. The situation has substantively changed as a result of the cemetery of Opushki excavations, which uncovered 17 burial vaults from the third century AD; every structure contained burials from the first half of the said century, with some burials probably dating back even earlier. This paper publishes some results of these excavations. It has been discovered that the first short-dromos burial vaults appeared in the Crimea much earlier than they were considered before, i.e., in the end or second half of the second century. Initially, dromos was not an inalienable element of the burial structure. The earliest burial structures under analysis obviously kept the Late Scythian traditions, such as many tiers of burials and moving aside the bones of those who were buried earlier. The combination of the burial vault construction, which was new in Crimea, and the traditional burial rites can hardly be explained otherwise than by physical contacts between the migrants and the autochthons. The origin of the migration of people who brought short-dromos burial vaults to Crimea was searched for in the North Caucasus. Among the stable specific rites documented in the third-century burials, there was charcoal bedding on the floor of the burial structure and beads embroidering the hem of gowns. These rites are typical of not only burials in vaults but also in undercut and simple pit graves. The core of the grave goods in the period in question is formed by a quite specific set of artefacts. Precisely the same goods were unearthed in the undercut and pit graves synchronous to the burial vaults.

Published: April 2024

The article is devoted to the problem of motivating students to engage in physical education at the university. The article presents the psychological and pedagogical conditions for the organization of athletic gymnastics classes, which contribute to increasing the motivation of students. To assess the effectiveness of the means and methods of pedagogical influence, a student questionnaire was used. 45 students of the Ural Federal University took part in the study. The results of the study revealed that when motivating students, it is necessary to use not only techniques and methods aimed at strengthening external motivation, but to a greater extent internal motivation. The development of students' internal motivation for classes ensures an increase in academic performance, a steady and significant increase in strength indicators in test exercises with a barbell, as well as commitment to athletic gymnastics not only during their studies at the university, but also in the future.
Characterisation, activation, and reactivity of heterogenous natural clays
Authors: Hazarika Amrita , Huang Liming , Babaahmadi Arezou
Published: April 2024

Although thermal and mechanochemical activations of natural clays are well-documented, there exists a dual research gap. Firstly, a thorough investigation into the interrelationship between these activation methods and the governing parameters of reactivity for various clays has been notably lacking. Secondly, there is a distinct scarcity of studies specifically focusing on heterogeneous clays compared to the extensive research dedicated to single-layer clays specially kaolinitic clays. This study investigates the correlation of activation methods, and changes in the clay mineralogy, particle size distributions, morphology, specific surface area, and the reactivity of heterogeneous clays. Traditional thermal and mechanochemical activation methods often fall short in achieving complete dehydroxylation of heterogeneous clay minerals and improving their reactivity beyond predefined low thresholds. The results in this paper emphasize that, despite these limitations, combining these activation methods brings about significant modifications in crucial parameters. Notably, integrating 20 min of mechanochemical activation at 500 rpm with prior thermal treatment leads to 158% increase in specific surface area compared to mechanochemical activation conducted on un-calcined clays. Simultaneously, these combined activations result in up to 127% improvement in reactivity levels of heterogenous clays compared to standalone mechanochemical activation. The results underscore that, even with the advancements brought about by combined activations, the presence of impurities like iron oxides and calcite remains a noteworthy factor influencing the reactivity of kaolinitic natural clays. The study concludes by highlighting the potential of combined treatments to enhance the pozzolanicity of low-reactive heterogeneous clays, unlocking avenues for future clinker supplementation with this abundant resource.

Abstract: An architectural design studio is a place for learning, experimentation, and exploration. Design of a built environment has constantly remained a collective activity where the architect, client, structural engineer, surveyor, service contractor, mason, and many others work together for a common goal. In the traditional design studio model, a student is expected to follow a set of design procedures like ideation, conceptualization iteration, and finalization to arrive at the outcome. He is supposed to design a built form based on context, climate, socio-economic parameters, and function using appropriate materials and technology. Often the process becomes a drool if the student is allowed to follow the sequence all alone. He or she may get stuck and lack motivation. But if the studio pedagogy involves discussion and an endeavor to explore rational thinking by adopting learning by doing together which may involve peer group discussion and continuous inputs from faculties, the process becomes much more interesting. A pupil studying architecture needs to cooperate and engage in design studios with his or her classmates and faculty. In addition, the students need to confederate, to achieve the objective of learning in a way that prepares them for the extremely synergistic phenomena of the architectural profession. (Crosbie, 1995; Daniels, 2002).This research aims to understand the effectiveness of design studios that can work in collaboration to refine every partaker’s contribution to the design methodology. The research was supervised as a semester-long exercise that integrated forty-six students from the first-year Architectural Design program, at KLE Technological University, India. The author explored quantitative analysis in the form of rubrics along with qualitative parameters like peer assessment, faculty feedback, and student response in the design process. .

Prácticas anticoloniales para reconstruir la memoria colectiva. De la iconoclastia al “artivismo”
Authors:   Universidad del Cauca, GONZÁLEZ TANCO Eva
Published: April 2024

En este artículo se describen las reflexiones construidas entre protagonistas y espectadores en un ejercicio de diálogo de saberes alrededor de las acciones iconoclastas llevadas a cabo por indígenas misak durante la protesta social en Colombia en 2021. Se propone la discusión desde la perspectiva teórica de la lucha anticolonial, que ayuda a interpretar estas acciones comunicativas como parte de un camino de liberación frente a estrategias identitarias e ideológicas impuestas que impiden la concreción autónoma del proyecto político del pueblo indígena. También se revisa cómo influyeron estas acciones sobre los marcos maestros de movilización de otros colectivos, y qué ha sucedido con los espacios físicos que ocuparon las principales estatuas derribadas en Colombia, para concluir si el artivismo como proceso comunicativo ayudó a resignificar estos espacios recuperados para una memoria liberada.
Cine: mirada y vínculo para transformar
Authors: Bolaños Tamia
Published: April 2024

La producción audiovisual de los pueblos y nacionalidades ha transitado un largo desarrollo social e histórico para ubicarse dentro del espacio visual del Ecuador y ser legitimada como parte de la identidad nacional. Esto ha significado una constante lucha de sentidos y poderes debido a que la imagen del indígena se ha constituido tradicionalmente desde la marginación y la exclusión. Poco a poco los representantes de esas comunidades han retomado espacios importantes para la vida social, política y cultural del país. Desde el séptimo arte, estas comunidades claman por recuperar también el derecho a mirar, ser mirados y ser productores de sus propias imágenes, porque el cine es considerado una importante arma política que tiene potencial emancipador.

The influence of crude oil (CRO) pollution on concrete compressive strength and durability performance is evaluated in this work. Due to CRO contamination on its compositions, concrete exposed to oil-prone areas may lead to considerable changes in its properties. Experimental work has been conducted, and several cubes of concrete with varying ratios of CRO pollution were treated to study the impact of pollution on the mechanical characteristics of the concrete. The current research methodology consists of preparing contaminants by mixing CRO in different ratios with fine aggregates and mixing it with other raw materials to produce polluted concrete. Twelve CRO ratios (0, 1, 2, 2.5, 3, 4, 5, 6, 10, 15, 20, and 25%) were utilized to test typical concrete slump, compressive, and tensile strength. Then, the same concrete procedure and testing were repeated by utilizing 2% CRO in the case of reactive powder concrete. The chemical test was also utilized to identify the changes in concrete composition for the three samples (standard concrete without CRO, standard concrete with 2% CRO, and reactive powder concrete sample). The experimental tests illustrated that a ratio of 2% of CRO in standard concrete improves compressive and tensile strength, while utilizing the same ratio in reactive powder concrete reduces strength. On the other hand, utilizing 2% CRO illustrates that the internal sulfate amount has been increased for both normal and reactive powder concrete compared with normal concrete samples without CRO, which refers to a reduction in concrete durability.

A critical commentary on the article “The Epistemic Harms of Empathy in Phenomenological Psychopathology” by Lucienne Spencer and Matthew Broome (2023) is presented. The authors committed the “fallacy of ambiguous or vague definition” by incorrectly interpreting Karl Jaspers’ conceptualizations, resulting in difficulties following logical arguments and arriving at reasonable conclusions. To overcome this fallacy, the commentary provides conceptual clarifications regarding Jaspers’ empathic understanding (einfühlendes Verstehen), conceived as the foundational concept of his project to develop a phenomenologically oriented psychopathology. Jaspers initially introduced this concept in the article “Die phänomenologische Forschungsrichtung in der Psychopathologie” [The Phenomenological Research Direction in Psychopathology], published in 1912, and extended in his magnum opus “Allgemeine Psychopathologie” [General Psychopathology], published in 1913.
Las metáforas importan: Desentrañando tres proposiciones esenciales
Authors:   Pontificia Università Gregoriana, Meza Diego
Published: April 2024

Este artículo examina el significado y la función de las metáforas en la configuración del conocimiento, las percepciones y decisiones en el ámbito de la salud. Al analizar críticamente su impacto tanto positivo como negativo, especialmente en la relación entre profesionales de la salud y pacientes, se proponen tres dimensiones para desentrañar su significado: la política, que las examina como agentes de poder y como instrumento para la legitimación de las desigualdades; la cultural, que considera las metáforas como sedimentos culturales que desafían el conocimiento biomédico predominante; y la ética, que cuestiona las implicaciones morales de las narrativas construidas. Este enfoque holístico busca mejorar la comprensión de la interacción compleja entre lenguaje, cognición y experiencia de enfermedad, promoviendo aproximaciones más completas en el ámbito de la salud.

El sector eléctrico colombiano cada vez recibe una mayor presión para que opere de una manera responsable. En ese sentido, un clima ético benevolente encaja con las expectativas de todas las partes interesadas. Asimismo, el compromiso afectivo, la motivación intrínseca y la autoeficacia son recursos personales imprescindibles para la sostenibilidad organizacional. Este artículo tiene como objetivo analizar el efecto moderador del compromiso afectivo y el mediador de la motivación intrínseca respecto a la relación entre clima ético benevolente y autoeficacia laboral. Se usa un modelo condicional, cuantitativo-correlacional. La muestra la componen 448 empleados con estudios universitarios. Un clima que se apoya en sentimientos de amistad, interés común y responsabilidad social regula las emociones y las impulsa en una clara dirección positiva, lo que nutre la identificación afectiva persona-organización y la motivación más íntima del empleado; además, ajusta e incrementa la autoeficacia laboral. El propiciar contextos laborales prosociales es prioritario en Colombia pues las organizaciones, y especialmente las públicas, no pueden apartar su mirada de los procesos éticos y de las necesidades sociales.

The Kalman filter, widely used since its introduction in 1960, assumes Gaussian random disturbances. However, this assumption can be inappropriate in non-Gaussian contexts, leading to suboptimal performance. Researchers have proposed robust filters like minimax filters to address this limitation, but these filters can overly conservative estimates. This research introduces a novel approach that combines unknown-but-bounded dynamics for the state process and stochastic processes for the measurement equation along with a Minimax Regret framework to improve state estimation in one-dimensional linear dynamic models. We evaluate the proposed method through two simulation studies. The first study optimizes the hyperparameter value using Grid Search. In contrast, the second compares the performance of the proposed method with conventional methods, including the Kalman filter and a robust version of the RobKF filter implemented in R software, using a suitable performance metric such as mean squared error. The results demonstrate the superiority of the proposed algorithm.

Published: April 2024

Background: Potato peel extract has demonstrated the ability to reduce platelet aggregation in vitro, suggesting its potential as a dietary intervention for preventing atherothrombotic disorders. Objective: This study aims to evaluate the impact of a potato peel-rich diet on platelet aggregation. Methods A randomized, crossover-controlled, open two-period study was carried out with the participation of 12 healthy volunteers. Platelet aggregation was assessed before and after a seven-day dietary intervention. Participants consumed either a diet rich in potato peel (2 g/kg/d) or acetylsalicylic acid (ASA) as a reference (100 mg/d). Platelet aggregation percentages were measured following stimulation with arachidonic acid (AA, 150 µg/mL), adenosine diphosphate (ADP, 10 µM), and collagen (COL, 10 µg/mL). Results: The potato peel-rich diet resulted in a slight but significant reduction in platelet aggregation when stimulated with arachidonic acid compared to baseline values (85.0±2.0% vs. 91.3±1.7%, p<0.05). This effect was less pronounced than the reduction achieved with ASA (16±1.9%, p<0.001). Conclusion: The administration of a diet rich in potato peel reduces platelet aggregation induced by arachidonic acid, suggesting its potential role in the prevention of atherothrombotic disorders.

Patrick Gordon entered the history of Eastern Europe as a companion of Peter I, commander of the Chyhyryn campaign of 1678, one of many foreign officers who formed regiments of foreign troops in the Muscovite state. Patrick Gordon came from a wealthy family in Aberdeen County, Scotland. Patrick’s childhood took place during the Civil War in England 1642–1651, so at the age of 16, Gordon’s parents sent Patrick to study at the Jesuit college in Braunsberg (now the city of Braniewo, Poland). Later, Patrick Gordon began his military career in the Swedish and then in the Polish armies and distinguished himself in important battles of the Northern War of 1655–1660. After the end of the hostilities, he received an offer from the Moscow envoy Vasyl Leontiev to serve in the Moscow army. Patrick Gordon agreed and, starting in 1661, served in Muscovy. The period of the 70s – 80s of the 17th century. in the life of Patrick Gordon is closely connected with the Ukrainian lands and the city of Kyiv. Patrick Gordon’s Ukrainian period is poorly researched, and most of the records representing the Scotsman’s stay in Ukrainian lands in 1667–1677 and 1678–1684 have been lost. The main source in the study of the biography of Patrick Gordon and the history of Eastern Europe is the unique diaries written by him. Volume 1 (1635–1659), Volume 2 (1659–1667), Volume 3 (1677–1678), Volume 4 (1684–1689), Volume 5 (1690–1695) have been preserved and published, Volume 6 (1695–1698). The diaries cover his entire life, from childhood to the beginning of 1699, a few months before his death. Volume 4 (1684–1689) testifies to Patrick Gordon’s stay in Kyiv. This scientific article aims to investigate and reveal Patrick Gordon’s stay in Kyiv during 1678–1684, his role in the construction of new defensive fortifications in the city based on the materials of the preserved diaries. As an engineer, P. Gordon organized the construction of a system of ramparts around Pechersk, Upper Town and Podil. At the end of the long work, in 1695, Colonel Ivan Ushakov compiled a map of the renewed Kyiv fortifications, the main role in the construction of which was played by Patrick Gordon. The article highlights the main districts of Kyiv at that time, explores the social topography and stratification of the city, highlights important events in the life of Patrick Gordon, presents events from the history of the Kyiv Metropolis and its annexation by the Moscow Patriarchate. The article is based on the materials of diaries that were published by historians during the 19th – 21st centuries.
