REVISITING THE ISSUE OF CONNECTIONS AMONG THE NOMADS SOCIAL ELITE FROM THE SOUTHERN URALS ACCORDING TO CRANIOLOGY DATA FROM THE FILIPPOVKA KURGANS
Authors: Khokhlov Aleksandr , Kitov Egor , Myshkin Vladimir
Published: April 2024

The article is devoted to the reconstruction of the relations of the nomads‘ social elite from the Southern Urals buried in the cemetries of the kurgans Filippovka 1, 2. The total craniological series of these monuments consists of 22 skulls (9 male and 13 female) representing brachycranial broad-faced Caucasoids. The aim of the study is to determine the historical roots of this group including their migration patterns, as well as their contacts with the surrounding population. The study is based on a comparative analysis of 35 craniological series of the Early Iron Age sites in the steppe and forest-steppe zones of Eurasia. The comparison was carried out according to the canonical analysis method using the Multican and Statistica 12 programs. In terms of morphological features, the individuals buried in the Filippovka kurgans are as close as possible to the nomads of the Southern Urals and the Lower Volga region of the Sauromatian (6th – 5th/4th centuries BC) and early Sarmatian (4th – 3rd centuries BC) time. They probably come from the local nomadic population who resided in this territory in early Sauromatian time. Representatives of the Filippovka group are also morphologically close to the Saka of the Aral Sea region and to the bearers of the Tasmolà culture from Central Kazakhstan. The formation of the pastoral population of the Early Iron Age (5th – 4th centuries BC) of two regions – the Southern Urals and the Aral Sea – might have taken place on a single anthropological basis, which is associated with the nomadic tribes of Central Kazakhstan including the bearers of the Tasmolà culture who had contacts with the Southern Siberia settled groups. As a result of mestizo processes on the contact territory, a special type of population the so-called Eastern Caucasoids with a small Mongoloid admixture was formed, which then spread in the southern Aral and western Ural directions. The spatial connections of the population that left the Filippovka kurgans are geographically wide. Judging by the archaeological data, they were grounded primarily on the basis of trade and economic relations. The craniological source shows some heterogeneity of the Ural nomads, but it is difficult to speak confidently about the time and mixing forms of their constituent components; the recorded phenomenon is also relevant among other synchronous groups of mobile pastoralists from Central Asia.
FIBULAE FROM THE UST-KAMENSKY CEMETERY IN THE LOWER DNIEPER REGION
Authors: Kropotov Viktor
Published: April 2024

This article is devoted to analyzing 24 fibulae originating from the Ust-Kamensk kurgan cemetery. Typologically, these finds are not very diverse. The bow fibulae (18 pieces) are the most numerous among them. Hinged arc-shaped brooches (3 pieces) and military clasps (2 pieces) are represented in a significantly smaller number. The spring fibulae with the button at the end of the continuous lamellar receiver are observed only in one fibula. The overwhelming majority of the specified decorations (21 pieces) form a single chronological group dated according to different chronological schemes to the second – third quarters or the second half of the 1st century – early 2nd century AD. Only three pieces do not belong to this group: two military fibulae date back to an earlier period and one spring fibulae with the button on the receiver end was made later. Taking into account modern research, military brooches cannot date back later than the early 1st century AD. The brooch with the button on the receiver dates back to the first half – middle of 2nd century AD. Considering that fibulae are the most reliable and precisely dated indicators in the inventory of the Ust-Kamensk kurgan cemetery, their dating can be confidently extended to the chronology of the whole burial ground. Thus, the monument was used for at least 100 years, from the early 1st century AD up to the first half – the middle of the 2nd century AD, but not just in the middle of the 1st – beginning of the 2nd centuries AD, as it was considered earlier. The majority of fibulae from the Ust-Kamensk collection have possibly been made in Olbia or delivered through it from the Roman provinces. Only the military brooches and the spring fibulae with the button on the receiver end, apparently, are of a different origin.
Political Self-consciousness of Captured White General Staff Officers Based on the Materials of Soviet Questionnaires of the Early 1920s
Authors:   Institute of Slavic Studies, Russian Academy of Science, Moscow, Ganin Andrey V.
Published: April 2024

Based on Soviet questionnaires of captured White General Staff officers of the early 1920s kept in the funds of the Russian State Military Archive, this article considers the problem of political self-identification of the “former” officers in Red captivity. The survey of former Whites was carried out to account for them. Sections of questionnaires about the prisoners’ attitude to the events of the February and October Revolutions, as well as about their current beliefs were of particular importance for assessing their views. The analysis of questionnaires as a mass historical source makes it possible to get an idea of the sociopolitical position of the group of captured White General Staff officers. On most issues, the prisoners’ views converged. As a rule, they accepted the February Revolution and did not accept the October Revolution. Also, they were highly critical of the old regime. Explanations of the reasons for the rejection of the seizure of power by the Bolsheviks are of considerable interest. For many, an acceptable answer was an indication of a lack of understanding of the tasks of the new revolution. At the same time, some pointed out the real reasons for such rejection, i.e. the Red Terror, the collapse of the old army, and the hard Brest peace treaty. The strategies used by the questionnaire compilers in answering acute and potentially dangerous questions draw the researchers’ attention. Often, the answers indicated that the revolution was of a popular nature, and the author of the questionnaire sought to serve the people or welcomed the rule of the people and was in solidarity with the policy of the RCP(b). Some authors, not wanting to express their true views, declared the need to work honestly for the benefit of society. The “former” tried to give answers that would appeal to the new superiors and regulatory authorities, which would allow them to integrate into the command structure of the Red Army more quickly and remove from themselves the discriminatory status of former White officers who were on special registry.
I. A. Puni as an Art Critic (Based on the Texts from 1914–1919)
Authors:   Ekaterinburg Museum of Fine Arts, Ekaterinburg, Galeeva Tamara A. ,   Ural Federal University, Ekaterinburg, Petkau Aleksandra Yu. ,   Ural Federal University, Ekaterinburg
Published: April 2024

This study examines the artistic and critical activity of I. A. Puni, a Russian avant-garde master and organiser of futurist exhibitions in the framework of his first creative period, preceding emigration. The opportunity to look from a historical distance at the time of the emergence of Russian avant-garde from the inside makes the study relevant. The researchers focus on valuable information about the time, the worldview of a curator/artist/critic (I. A. Puni being all of them) and the “pain” points of art. The conclusions are based on the multidimensional textual material (critical articles, letters, lecture materials), which helps immerse in the context of artistic life in Petrograd and Vitebsk at the beginning of the century. Using structural and semiotic analysis, the authors draw parallels with I. A. Puni’s painting and curatorial experience. Puni’s focus is on the theoretical aspects of the new art that concerned him as an artist. His texts raise polemical questions about the importance of “material culture”, the role of the artist, futurism, and curatorship. In an era dominated by production art and the principles of utilitarianism, Puni emphasises the value of the artist’s individuality, their understanding of aesthetic tasks, and the intellectual content of the visual narrative. For Puni, the beauty of art lies in its uselessness for life: it is utilitarian production that influences art, not the other way around. Through coloured materiality, peculiarities of composition and form, the artist emphasises the essence and the inner construction of the depicted object. The study notes the special stylistics of Puni’s texts, based on the neutrality of tone, reasoned judgments, which was not typical of theorists in the era of “poster language”. The artist’s curatorial activity, manifested by the landmark exhibitions “Tram B” and “0.10”, gives an example of a “critic in action”. The materials analysed show the complexity of the choice of objects capable of driving the narrative and the importance of one’s own position in the aspect of the rivalry between K. S. Malevich and V. E. Tatlin.

CYLINDRICAL CROSS-BARS FOR THERMAL PERFORMANCE AUGMENTATION IN AIR CHANNEL
Authors: Coetzee Frans J.J. , Mahmood Gazi I.
Published: April 2024

Experiments of the heat transfer and pressure drop are performed in a rectangular channel employing eight different arrays of cylindrical cross-bars as inserts. Numerical simulations are also performed to examine the secondary flow caused by the cylinders. The objectives are to investigate the enhancement of the channel-wall heat transfer and pressure drop caused by the local flow, cylinder array geometry, and flow Reynolds number. Two different cylinder diameters of 1.0 mm and 2.0 mm are employed. The diameter of 2.0 mm is used to create four in-line arrays while the diameter of 1.0 mm is used to create four staggered arrays of the cylinders. The cylinder arrays employ different diameter-to-pitch ratios (0.025 to 0.2) and cylinder orientations (45°, 90°) relative to the main flow direction. The flow Reynolds number is varied between 600 and 13,000. Only two array geometries, one in-line and one staggered, with the cylinders oriented at 90° to the flow are modeled for the numerical study. The numerical results show that the local flow accelerates in the gap between the cylinder and channel wall. The vortex shedding downstream of the cylinders interacts with the channel wall. The Nusselt number on the channel wall and the friction factor are measured with and without the cylinders. The ratios of Nusselt numbers and friction factors increase with the Reynolds number when the Reynolds number is less than 3000. The ratios always increase with the diameter-to-pitch ratio.
ROLE OF DUAL CAVITY ON THE COMBUSTION PERFORMANCE OF A SPLITTER PLATEâASSISTED SUPERSONIC COMBUSTOR
Authors: Choubey Gautam , Beeraka Sai Tanmay Veerendra , Trivedi Rishi , Ingenito Antonella
Published: April 2024

An unsteady-state simulation using Reynolds-averaged Navier-Stokes was conducted to explore the performance of an ethylene-fueled scramjet combustor employing a dual cavity floor injection strategy and a splitter plate. The validity of this approach was confirmed by comparing it to experimental data, which showed a reasonable match between
the observed experimental results and the simulation. A thorough analysis of the injection system's performance
is conducted using variables such as the scramjet combustor's total pressure loss, wall pressures, and combustion efficiency. The findings revealed that the leading edge cavity shock waves' interaction from both the walls created a highpressure area close to the cavities, which forces the fuel jets in the direction of the combustor walls. Fuel distribution into the combustor is thereby prompted by the intense interactions that arise between the cavity's aft walls and fuel jets. Moreover, the recirculation zones within the cavity are significantly expanded, improving both the performance of combustion and mixing within the cavity. The combustion efficiency in the current study has shown a notable increase of 13% compared to our previously investigated configuration involving a splitter plate combined with a single cavity combustor.

Published: April 2024

In order to accurately evaluate the deterioration of the mechanical properties of concrete reinforced with steel fibre (SF) after exposure to elevated temperature, it is particularly important to study the bonding properties between the SF and the concrete matrix. In this work, four types of SFs and five cement mortars with different strengths were used to investigate the bond behaviour of the SF–mortar interface after exposure to elevated temperature. The results showed that the compressive and flexural strengths of each mortar decreased significantly after elevated temperature treatment, and the attenuation degree of flexural strength was greater than that of the compressive strength. In addition, the ultimate pull-out load of specimens with straight SFs gradually decreased with an increase in exposure temperature. However, the ultimate pull-out load of specimens with hooked-end SFs showed no significant change between exposures to 20°C and 400°C. When the exposure temperature exceeded 400°C, the ultimate pull-out load gradually decreased with an increase in temperature. The damage mechanism of the SF–mortar interface under elevated temperature was investigated by analysing the interfacial microstructure and phase change of cement pastes. Finally, a formula to related the ultimate bond strength with temperature was established.

Computer-based simulations have gained significant popularity in science education, particularly in subjects like Physics that involve intricate and abstract concepts. Simulations offer learners the opportunity to engage with complex phenomena and manipulate them, making them particularly valuable in these contexts. In line with this notion, our study adopted a teaching strategy centered on simulations. This approach was implemented in two separate classes of first-year Bachelor of Technology (F. Y. B. Tech) students, specifically for the Engineering Physics course. In one of these classes, simulations were solely utilized without incorporating any formative assessment, while the other class was exposed to a strategy that combined simulations with formative assessment. Our observations revealed that solely using simulations during instruction did not contribute significantly to conceptual understanding. However, when simulations were integrated with formative assessment, a substantial improvement in understanding was noted. Through our data analysis, a noteworthy discrepancy in average scores between the two classes became apparent. Notably, the class that experienced the simulation-based formative assessment strategy demonstrated a higher average score of 63.85.

Stanisław Moniuszko as a Teacher
Authors: Baranowski Tomasz
Published: April 2024

The aim of this article is to paint the full picture of Moniuszko as a music teacher. Although teaching was a sideline to the composer’s professional activity, he was engaged in it for most of his life. During his Vilnius period, Moniuszko gave many private lessons, which constituted an important part of his income. Among his students were many eminent figures, such as the painter Wincenty Sleńdziński, the ethnologist Jan Karłowicz (the father of Mieczysław Karłowicz) and the Russian composer César Cui. Moniuszko then took up teaching – now in a professional capacity – as a professor at the Music Institute in Warsaw, headed by Apolinary Kątski. There, he led a choir class and taught composition, harmony and counterpoint. The study is complemented by the memories of his students, including such famous musicians as Zygmunt Noskowski and Władysław Rzepko.

This review explores the burgeoning field of microbially enhanced construction materials, with a special focus on self-healing concrete, through the lens of microbial biotechnology. Central to this discourse is the innovative use of bacteria, particularly Bacillus species, to address the pervasive issue of microcracks in concrete, a fundamental material in the construction industry. Traditional remedies, such as chemical admixtures and fiber reinforcements, offer partial solutions; however, self-healing concrete represents a paradigm shift, harnessing the natural calcite-precipitating ability of bacteria to autonomously repair cracks, thereby augmenting structural durability and longevity. Delving into the mechanics, the bacteria, embedded within the concrete matrix, remain dormant until crack formation triggers their metabolic pathways, leading to calcite production that effectively seals the fissures. This bio-mediated repair mechanism not only enhances the structural integrity of concrete but also aligns with sustainable construction practices by minimizing maintenance requirements and material wastage. The review extends beyond self-healing phenomena, encompassing broader applications of microbial technology in construction, including bio-concrete, bio-cement, and soil stabilization methods. These applications underscore the versatility of microbes in enhancing material properties such as compressive strength, tensile resilience, and water impermeability. Empirical evidence underscores the necessity of optimizing bacterial dosages and curing conditions to maximize the self-healing efficiency. Future research trajectories should aim to elucidate the complex interactions between microbial agents and concrete matrices, assess long-term performance, and evaluate the environmental and economic sustainability of microbial interventions in construction. The integration of microbial technology in construction materials heralds a new epoch of innovation, offering robust, sustainable, and resilient solutions to enduring challenges in the industry.
Experimental study on the utilization of construction and demolition waste of recycled aggregate with GGBS and I-Crete in pavement quality concrete
Authors:   Civil Engineering Department, Andhra University, Babu B. Chitti , Rani K. Durga ,   Civil Engineering Department, Andhra University
Published: April 2024

This study investigates the mechanical properties of M40 concrete in Pavement Quality Concrete (PQC) by incorporating Recycled Aggregates (RA) from construction, demolition waste and industrial wastes, such as GGBS and I-Crete, for sustainable pavement construction. The research explores varying proportions of RA (25% to 100% by weight in 25% intervals). Results show concrete mechanical strength decreases with higher RA proportions but all mixes still meet target strength criteria (compressive, flexural, split tensile) at 7, 28, and 90 days of curing. Further testing on 100% RA (MRCA-100) with GGBS admixture from 5% to 35% in 5% increments found strength improves significantly up to 10% GGBS replacement by cement weight, with subsequent decreases at higher percentages Initially. Then introducing the mineral additive, I-Crete at 2% by weight of cement in 15% to 35% GGBS range results in notable strength enhancement, peaking at 25% GGBS replacement. Ultrasonic pulse velocity (UPV) and water absorption tests showed similar trends in 28-day strength across all mixes. Increased strength from better bonding was observed, with Scanning Electron Microscopy (SEM) showing enhanced hydration and bonding due to mineral admixture and additive. These findings underscore the efficacy of such additives in enhancing the mechanical strength of sustainable PQC.

Authors: Ishmuratov E. V. , Zuev A. A.
Published: April 2024

Success of surgically treated epilepsy depends on the accuracy of epileptogenic zone localization. Single-photon emission computed tomography (SPECT) using SISCOM (subtraction ictal SPECT co-registered to MRI) protocol is the only imaging method that allows identification of ictal onset zone by injection and fixation of a special radioactive tracer in the area of increased cerebral blood flow. The review outlines the key stages of SPECT using SISCOM protocol, generalizes and analyzes data for related opportunities and disadvantages as well as its prospects for use in preoperative examination of patients with epilepsy. It was demonstrated that the technique showed high sensitivity (mean 70–75%) to localize epileptogenic zone in patients with pharmacoresistant epilepsy in case if brain structural changes were not detected by magnetic resonance imaging (MRI). However, the organizational features of the procedure in combination with its specific limitations for epilepsy patients do not allow it to be considered as a routine diagnostic method.

Background. Given the difficulties in identifying absences and assessing the level of consciousness in epilepsy patients, it is extremely relevant to develop digital programs for automatic registration and testing of this type of epileptic seizures and related electroencephalographic (EEG) patterns, including those based on artificial intelligence.

Objective: development of an algorithm for automatic detection of absence seizures to test real time patient's consciousness level during long-term video-EEG monitoring.

Material and methods. The work on creating an algorithm was carried out during joint doctor/engineer cooperation. Doctors prepared a set of labeled EEG recordings of patients with verified absence epilepsy. Two independent experts in the generated examinations database mapped typical episodes of absence seizures that allowed to develop training and testing samples for a neural network algorithm to detect EEG absence epiactivity. Next, trained neural network was incorporated into Neuron- Spectrum.NET software to compare its accuracy with similar approaches published elsewhere.

Results. A neural network algorithm was developed and trained using a mapped database to detect EEG absence epiactivity. A comparative analysis of the effectiveness for the proposed method vs. other approaches showed that the former is comparable in quality, whereas in some aspects – even superior to the latter. Accuracy was assessed using a publicly available database with mapped epiactivity episodes.

Conclusion. A hardware and software system for automated assessment of patient’s consciousness level during absence seizure in continuous video-EEG monitoring was proposed. Potentially, neural networks may be applied not only to assess patient’s consciousness level, but also to stop stimulation-mediated seizure onset in the future.
In vitro fertilization for endometriosis-associated infertility: A literature review
Authors: Sarkisyan Emilia A. , Svidinskaya Evgeniya A. , Ageev Mikhail B. , Sosnova Elena A.
Published: April 2024

This article analyzed the work of Russian and international authors over the past 10 years on the effect of endometriosis on the development of infertility and evaluated studies on the analysis of in vitro fertilization procedures in patients with this condition. Every third patient who uses assisted reproductive technology (ART) suffers from endometriosis-associated infertility. Endometriosis is a significant cause of this disease, and its clinical forms and the degree of foci spread often limit doctors’ choice of ART programs, which do not always result in pregnancy. Cystic ovarian endometriosis is one of the most common forms of endometriosis. Controversy surrounds the treatment of this form; some authors advocate hormonal therapy (to preserve the ovarian reserve), whereas others believe that more radical surgical treatment helps reduce relapses. In any case, several factors must be considered when choosing the optimal treatment approach for women with ovarian endometriosis and infertility, including the age of the patient, presence of pain, outcomes of previous surgeries, size and number of cysts, preserved ovarian reserve, and access to the follicles. These factors prove the relevance of this condition, which requires a modern approach to its diagnosis and treatment.

Em março de 2020, a COVID-19 foi caracterizada pela OMS (Organização Mundial de Saúde) como pandemia, ocasionando, dentre outras consequências, a paralisação de diversas atividades econômicas, onde seus impactos até hoje afetam o cotidiano das organizações O objetivo desse artigo, foi investigar os principais desafios e estratégias em período pandêmico sob a visão de microempreendedores individuais. Esse estudo foi realizado por meio de entrevistas que ocorreram de forma presencial, onde os resultados da primeira parte da pesquisa, referente ao perfil dos empresários, foram basicamente os mesmos, empresários, jovens, de nível superior, com atuação no mercado inicialmente de forma irregular, e logo após a estabilidade de suas empresas, por meio da legalização e abertura do MEI. Na segunda parte da pesquisa, pontuou-se as estratégias que foram utilizadas, e também destacou-se o apoio que esses microempreendedores tiveram no período pandêmico, com a finalidade de melhorar o atendimento ofertado pelas empresas, ampliar os horizontes na captação de novos clientes, e na fidelização dos mesmos, as principais estratégias utilizadas que foram o marketing digital, as entregas por meio do delivery e a utilização de kits descartáveis no atendimentos aos seus clientes, para finalizar esse estudo teve o intuito de enfatizar os desafios impostos aos microempreendedores e pontuar as estratégias que eles utilizaram, para enfrentar esse período de crise pandêmica.
Transparência das contas públicas à luz do Art. 48 da Lei de Responsabilidade Fiscal: um estudo multicaso no cariri ocidental paraibano

Published: April 2024

A presente pesquisa objetivou analisar a transparência das contas públicas no portal eletrônico dos dez maiores municípios do Cariri Ocidental Paraibano à luz do art. 48 da Lei de Responsabilidade Fiscal - LRF. Para atingir o objetivo foi realizado um estudo classificado quanto aos objetivos como descritivo, quanto aos procedimentos, documental e bibliográfico, quanto a abordagem do problema quantitativo e qualitativo. A amostra da pesquisa é composta pelos dez maiores municípios que compõem o Cariri Ocidental da Paraíba. O recorte temporal escolhido para a investigação foi entre os anos de 2018 a 2022, tendo em vista que buscou-se realizar uma pesquisa recente das informações. Os dados foram analisados através da estatística descritiva. Como principais achados observou-se que no Portal de Transparência do município de Sumé não foram encontradas nenhuma das informações que estão elencadas no art. 48 da LRF nos        anos analisados. No que diz respeito aos demonstrativos, as prestações de contas apresentaram baixo nível de divulgação por parte das prefeituras, pois apenas 30% destas divulgaram de maneira integral. O parecer prévio apresentou o menor índice de transparência, considerando que apenas foram encontradas informações nos portais de transparências das cidades de Camalaú e Congo. A Lei de Responsabilidade Fiscal é considerada um marco no que diz respeito às finanças públicas, contudo, ainda há muita coisa para ser melhorada, tendo em vista que apesar desta elencar os demonstrativos que devem ser   dada ampla divulgação nos portais eletrônicos dos municípios, muitos desses não cumprem o que dispõe a referida lei.
Gestão de ativos e passivos de fundos de pensão em linguagem R: modelagens cash-flow matching, risk parity e maximo sharpe
Authors: Silva Natália Freitas da , Santos Júnior Luiz Carlos
Published: April 2024

Devido à importância de uma boa gestão em uma entidade de previdência, dado que um investimento inadequado pode impactar negativamente a economia do país, o presente trabalho busca elucidar o uso de três modelos de gestão de ativos e passivos – Cash-Flow Matching, Risk Parity e Máximo Sharpe – em linguagem R e no âmbito dos fundos de pensão. Dessa forma, os modelos foram apresentados e implementados a partir de situações hipotéticas. Dada a intenção de explanar a otimização de funções objetivo (minimizar o custo da carteira, minimizar a contribuição marginal de risco e maximizar o índice de Sharpe) e  considerando algumas restrições – a) igualdade entre recursos garantidores e provisões matemáticas e b) quantidades de ativos a serem adquiridas maiores ou iguais a zero – foram obtidos os seguintes resultados: o modelo Cash-Flow Matching sugeriu uma carteira composta por 5 ativos de renda fixa; numa comparação entre os modelos de Risk Parity e de Máximo Sharpe, constatou-se que o primeiro apresentou melhores métricas e indicou a composição de uma carteira com 5 ativos de renda variável. A despeito desses resultados, apresentaram-se as principais definições e formulações, além de código em R, que permitem a familiarização e implementação de modelos de gestão de ativos e passivos aplicados a fundos de pensão, atendendo, assim, aos objetivos deste trabalho e do projeto de iniciação científica a ele vinculado: a elaboração de um material didático.
