Identities relating six members of the Fibonacci family of sequences
Authors: Frontczak R. , Goy T. , Shattuck M.
Published: April 2022

In this paper, we prove several identities each relating a sum of products of three terms coming from different members of the Fibonacci family of sequences with a comparable sum whose terms come from three other sequences. These identities are obtained as special cases of formulas relating two linear combinations of products of three generalized Fibonacci or Lucas sequences. The latter formulas are in turn obtained from a more general generating function result for the product of three terms coming from second-order linearly recurrent sequences with arbitrary initial values. We employ algebraic arguments to establish our results, making use of the Binet-like formulas of the underlying sequences. Among the sequences for which the aforementioned identities are found include the Fibonacci, Pell, Jacobsthal and Mersenne numbers, along with their associated Lucas companion sequences.
An evolution of the book tradition in Transcarpathia
Authors:   Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine, Kotsa Ruslana
Published: April 2022

The evolution of language is determined by social, historical, and cultural factors. Over the 14th—15th centuries Transcarpathia was a part of the Kingdom of Hungary with the official Latin language being actively used by the Catholic Church. At that time Orthodox Church dominated in the region, and Mukachevo and Hrushovo monasteries served as the most important cultural and educational centers. Monks copied and distributed religious texts in Church Slavonic within the community. This paper discusses religious and secular written records extant from Transcarpathia, e.g., Uzhhorod Half-Uncial (the late 14th and early 15th century), Mukachevo Psalter (the 15th century), Korolevo Gospel (1401), and the 1401 and 1404 charters. The author looks into the feature of the language used in the aforementioned documents and argues that religious texts are marked with Ukrainian Church Slavonic properties and nonreligious texts with Middle Ukrainian properties. The second South Slavic influence as reflected in spelling alongside vernacular Ukrainian allows to speak not only about the Middle Ukrainian language foundation of the Transcarpathian written records but also about some Transcarpathian dialect features. A lack of secular records, i.e., official documents, reflecting predominately vernacular elements, except for the copy of the 1404 charter, gives, however, a vague idea of Middle Ukrainian language of administration and complicates the study of the history of the Transcarpathian dialect. Keywords: Middle Ukrainian, Ukrainian Church Slavonic, the 14—15th century written Transcarpathian records, Transcarpathian dialect
Language and national issue in Valerii Marchenko’s opinion journalism and epistolary
Authors:   National University of Kyiv-Mohyla Academy, Renchka Inna
Published: April 2022

A resistance movement of the Ukrainian intelligentsia which opposed the colonial state of Ukraine in the USSR and the Russification of Ukrainians emerged in the 1960s—1980s. The activists of this movement, namely writers, artists, teachers, journalists, and scientists, paid a great attention to the language issue in their creative, educational, and public activities due to severe oppressions on functionality of the Ukrainian language in the Soviet Union as well as losing its originality by assimilation. The goal of this article is to study current language issues raised in the opinion journalistic works and letters of a member of the resistance movement, Ukrainian dissident, journalist, and writer Valerii Marchenko, and to examine his views on the language situation in Ukraine and the national policy in the USSR as well as his activities in defense of national values. Marchenko’s opinion journalistic and epistolary heritage is of a great research interest from a linguistic perspective. In the articles based on his own observations and the stories of other political prisoners, he uncovers the situation of the Ukrainian language in Soviet Ukraine. He provides and analyzes the facts that highlight the language situation in the USSR, in particular in education, science, publishing, music, and film production, in the period from the 1950s to the mid-1980s. The author analyzes the reasons why Ukrainians reject their mother language. He concludes that the main reason for this was the dominant policy conditioning a higher social status of Russian and the lack of prestige of national languages. Another reason was the security factor since accusations of ‘Ukrainian nationalism’ were widespread. Marchenko’s works un covering interdiction policy in literary translations in the early 1970s are of particular importance for the study of the language situation in Soviet-era Ukraine. The author considers these interdictions as a political campaign against Ukrainian translators and the language of the Ukrainian translations. The creative heritage of the Ukrainian human rights activist confirms that the issue of the preservation, free development, and full-fledged public functioning of the Ukrainian language in Ukraine as an independent state was a central one for Ukrainian dissidents and their predecessors, namely past-centuries libertarians of Ukraine and national liberation participants of the mid-20th century. Keywords: Ukrainian language, Russification, resistance movement of the Ukrainian intelligentsia, language policy, national policy, language situation, Soviet totalitarian regime, cultural colonization, translation, Valerii Marchenko

Development of Driving Cycle for Passenger Cars and Estimation of Vehicular Exhaust Emission Factors
Authors: Muhammad Jahanzaib
Published: April 2022

Driving pattern of the given vehicle in a city is represented by the driving cycle which is used by modal models for estimation of vehicular emissions. In this study, a driving cycle was developed for passenger cars in the city of Islamabad. A representative route for city was identified which included parts of highway, arteries, and streets. Speed-time data was collected along the selected route in both peak and off-peak hours. The on-board measurement method was adopted for data collection on highways, whereas on arteritis and streets, chase car method has opted for data collection. The developed cycle showed comparable values of average speed and acceleration with New European Driving Cycle (NEDC), but acceleration and deceleration were observed to be lower. The emission estimation and fuel consumption were calculated by the Comprehensive Modal Emission Model (CMEM) for 4 selected vehicle types. The average emissions for the selected vehicles were 204.4 g CO2 /km, 2.3 g CO /km, 0.09 g HCs /km, 0.31 g NOx /km emitted, and 65.7 g of fuel consumed /km. The developed cycle showed higher fuel consumption and CO2 emissions /km traveled than NEDC for all 4 passenger car types. However, HCs, CO, and NOx emissions were lower. The developed driving cycle can be used for estimation of the emissions from passenger cars in the city and this information can be useful for future emission projections and policy making.
Dynamics of the chemokine ENA-78/CXCL5 levels in blood serum and skin exudate in patients with atopic dermatitis
Authors: Kibalina I. V. , Tsybikov N. N. , Fefelova E. V.
Published: April 2022

Currently, there are only scarce data on dynamics of biologically active substances in the lesions associated with atopic dermatitis. Persistence of microorganisms in atopic dermatitis is high on the skin surface. However, pathophysiological significance of ENA-78/CXCL5 for development of atopic dermatitis was not studied so far. The ENA-78/CXCL5 is known to be produced by endotheliocytes, keratinocytes, eosinophils, fibroblasts to activate neutrophil migration, especially under the influence of LPS-containing microorganisms. The aim of this study was to evaluate the dynamics of ENA-78/CXCL5 chemokine levels in blood serum and skin exudates in the patients with atopic dermatitis, as well as to determine pathophysiological role of the chemokine in pathogenesis of dermatosis. 80 patients with limited and widespread forms of atopic dermatitis and 15 volunteers were under observation. The dynamics of ENA-78/CXCL5 levels was studied in blood sera and skin exudates. Blood samples for the study were drawn at the time periods of exacerbation and remission. Skin exudates were taken from the patients during the exacerbation period using disposable insulin syringes and 20-G disposable needles. In healthy volunteers, the skin exudate was obtained by the “skin window” technique as described by V.V. Klimov and coauthors “A method for assessing minimal inflammatory activity of skin in atopic dermatitis in remission”. The cell analysis was conducted by flow cytofluorimetry using the LEGEND plex TM Human Proinflammatory Chemokine Panel (USA) according to the manufacturer’s protocol. Serum concentrations of chemokine ENA-78/CXCL5 in adolescents with atopic dermatitis, exceeded the range for healthy volunteers. During remission of dermatitis, the chemokine level did not reach the indices in the control group. In adults, the ENA-78/CXCL5 concentration, both at the onset of symptoms and upon their resolution, was below the control levels. Maximal concentrations of ENA-78/CXCL5 chemokine were detected in the skin exudates. As based on our data on the dynamics of ENA-78/CXCL5 chemokine levels, it could be assumed that this substance may represent a sufficient link in pathogenesis of atopic dermatitis, by causing migration of neutrophils and monocytes to the affected area. The ENA-78/CXCL5 chemokine may be a marker of microbial pathogenesis and cellular damage in atopic dermatitis.
FOXP3, IL2R, CD8A and RORγ gene expression in peripheral blood leukocytes of healthy people and patients with arterial hypertension
Authors: Topchieva L. V. , Korneva V. A. , Malysheva I. E.
Published: April 2022

Impaired balance of T regulatory and T effector lymphocytes has recently been considered as an important pathogenetic link in arterial hypertension (AH). There are, however, contradictory literature data about contents of these cells in the patients with hypertension, or obtained in experimental animal models of induced hypertension. Most results about changed patterns of immune cells in cardiovascular diseases were obtained by means of flow cytometry. There are also some works on expression of genes encoding surface and cytoplasmic differentiation antigens of immune cells in the patients with cardiovascular pathologies. These results coincide with the data obtained with flow cytometric techniques. Purpose of the present study was to analyze of the levels of gene transcripts encoding differentiation markers of regulatory (FOXP3, IL2R) T cells, effector T subpopulations (T helpers 17 (RORγ), and CD8 lymphocytes (CD8A) in healthy subjects and the patients with arterial hypertension (stages I-II). We examined healthy individuals (40 people, 20 men and 20 women), 27 patients with hypertension who did not receive antihypertensive therapy (14 men and 13 women), 26 hypertensive patients taking β-adrenergic receptor blockers (metoprolol or bisoprolol), including 12 men and 14 women. The relative levels of transcripts in peripheral blood leukocytes were assessed by real-time RT-PCR. It was shown that the transcriptional activity of FOXP3, IL2R, RORγ, and CD8A genes in peripheral blood leukocytes of the diseased people was significantly higher than in healthy individuals (p < 0.01). This finding may indicate an increased number of circulating T regulatory lymphocytes, CD8+ cells and T helpers 17 in hypertensive patients, and activation of T cell immunity in these patients. There were no statistically significant gender differences in FOXP3, IL2R, RORγ and CD8A gene expression in leukocytes, both in the group of healthy people and in hypertensive patients. The patients receiving cardioselective β-adrenergic receptor blockers (metoprolol and bisoprolol) exhibited lower expression of these genes, thus, probably, indicating antiinflammatory and immunomodulatory properties of these drugs.

The last fifteen years have been marked by rapid progress in the study of neutrophils. The discovery of transcriptional plasticity of neutrophils, their phenotypic and functional heterogeneity contributed to launching active interdisciplinary studies on the role of neutrophils in various chronic inflammatory diseases. Increased systemic circulation of immunosuppressive neutrophils can be observed not only in sepsis, but also in chronic systemic inflammation, which, along with disorders of lipid metabolism, is the major mechanism of atherosclerosis development and progression. Monocytes, dendritic cells, Tlymphocytes and neutrophils are key participants and modulators of inflammation in atherosclerosis. Potential significance of immunosuppressive neutrophils in atherogenesis and regulation of inflammatory response in atherosclerosis has not been currently established. However, taking into account their possible effects upon T lymphocytes and innate immunity cells, the study of immunosuppressive neutrophils seems promising in the context of atherosclerosis and atherosclerotic cardiovascular diseases. The purpose of this study was to evaluate relationship between the numbers of circulating immunosuppressive neutrophils and subpopulations of T cells and monocytes in the patients with subclinical atherosclerosis. The study enrolled patients aged 40-64 years with subclinical atherosclerosis of peripheral arteries. Subpopulations of neutrophils, lymphocytes and monocytes were phenotyped by flow cytometry using “Navios 6/2” (Beckman Coulter). 133 patients, 65 (48.8%) males and 68 (51.2%) females were included into the study. Correlation analysis showed that increased number of circulating CD16hiCD11bloCD62Lbr neutrophils was associated with increased number of regulatory T lymphocytes. The patients with subclinical atherosclerosis and absolute numbers of circulating immunosuppressive neutrophils within the first quartile (<136 cells/μL) had a statistically significantly lower number of regulatory T lymphocytes compared with patients in the 2-4 quartiles. An increase in immunosuppressive neutrophils was associated with decreased number of classical monocytes expressing TLR4 (r = -0.335; p = 0.004), and a decrease in TLR2 surface expression intensity (r = -0.268; p = 0.023) on the non-classical monocytes. In patients with subclinical atherosclerosis of 40-64 years old, an increase in immunosuppressive CD16hiCD11bloCD62Lbr neutrophils was associated with increase in regulatory T lymphocytes and nonclassical monocytes, as well as decrease in classic monocytes expressing TLR4, and lower intensity of TLR2 expression on the non-classical monocytes.
Modern biotechnological methods in wastewater treatment: a review
Authors: Beya C. L. , Kanwugu O. N. , Ivantsova M. N.
Published: April 2022

Given that water is the main solvent in living organisms as well as in domestic and industrial activities, it must be treated as carefully as possible after multiple uses to get a harmless water quality. To remove the undesirable materials (e.g. organic matters, surfactants, petroleum products, unwanted metals, dyes, et.), the physicochemical water treatment process is used as the common method. This method of wastewater treatment uses flocculation – coagulation technique, which consists of mixing coagulant matters with water to collect, in solid clusters, the materials in suspension by gravity. Recently, environmental scientists have suggested biotechnology methods as the main alternatives in the treatment of wastewater, as they offer more benefits to the water quality and human health than chemical methods. This paper describes and assesses some modern biotechnology methods used in wastewater treatment.
The Name Alexander in the Anthroponymy of the Pre-Revolutionary Russian Nobility
Authors:   Russian State University for the Humanities, Pchelov Evgeny V.
Published: April 2022

The paper aims to evaluate the incidence of the name Alexander among the oldest families of the Russian nobility during the 14th — early 20th centuries. One of the key questions is whether the tradition of this name’s popularity in the ruling dynasties in Russia was related to the historical memory of Alexander Nevsky, his canonization and the prominence of his figure in the first quarter of the 18th century. The study is based on the corpus of genealogies of the Russian aristocracy and ancient noble families that allows the author to track the naming trends over several centuries. With reference to the name Alexander, the following patterns were revealed: it was established that the personality of Alexander Nevsky influenced the popularity of his name among the princely dynasties of Russia, including those distantly related to the prince himself. In the Muscovite dynasty, the name disappeared, while in separate branches of the Rurik dynasty, it was preserved thanks to the historical memory of its other bearers. In the 15th –16th centuries, the name Alexander was relatively popular among the elite but the all-Russian canonization of Alexander Nevsky in the 1540s had no significant impact on it. In the early 17th century, the name is barely mentioned in the genealogies, but since the last quarter of the century it regains its former popularity. It is booming all through the first half of the 18th century which only partially correlates with the relevance of the image of Alexander Nevsky during Peter the Great’s rule. By that time, this name had become a trend among Russian nobility, and there was nothing extraordinary about the future emperor getting the name Alexander Pavlovich. Another peak in the popularity of the name occurred in the late 18th — early 19th century, which is largely due to the success of the reign of Alexander I. During the 19th century, the name became one of the most common among the Russian nobility.
Naming and Identities of Germanic Immigrants in the Eastern Roman Empire (5th–6th Centuries)
Authors:   Ural Federal University, Nazarov Andrey D.
Published: April 2022

The article studies naming conventions among Germanic immigrants who settled in the Eastern Roman empire during the Migration Period. The author uses information from both narrative and epigraphic sources. Many immigrants, finding themselves in a cultural environment alien to them, sought to preserve their own identities. As a means of maintaining family memory, some Goths who lived in Byzantium gave their children names that would testify to their Kinsmanship. This was typical of some families among the highest Byzantine nobility having barbarian origins. This indicates that the social environment of these immigrants and their descendants generally treated them favorably. However, since the second half of the 6th century, members of such families began to appear mainly under Greek and Latin names, which can be stemmed from the growth of religiosity in the aristocratic circles. The processes of integration and assimilation for ordinary migrants largely depended on the social environment and the nature of contacts with it. Thus, many Goths who lived in Thrace retained their identities at least until the end of the 6th century. In all likelihood, they lived apart from the indigenous people. As a result, the tradition of naming their own descendants by Germanic names existed among them for a long time. Finally, Goths, whose military service took place in Asia Minor, quickly assimilated to the new environment. In all cases known to us, their sons received non-Germanic names.
Variable Forms of Naming in Literary Texts of Nikolay Gumilyov: Poetical and Semantic Aspect
Authors:   I. M. Sechenov First Moscow State Medical University, Fedotova Kseniya S.
Published: April 2022

The article deals with poetical and semantic aspects of the analysis of variable onym nominations in literary texts of an eminent Russian poet Nikolay Gumilyov. It is shown that within one poetic text, synonymous names can replace an unmentioned proper name (as in The Jaguar), form a speech portrait of a character (The Funny Brothers) or express his attitude towards the addressee of speech (The Child of Allah). Variable proper names can differ by phonemic structure (Dante — Dant, Eros — Erot) or name formulas (Igor Severyanin — Severyanin). The poet uses some proper names variants from different languages and ethnic groups, for example, the poetonym Bornu characterizes the poetic space as it can be seen by inhabitants of the described places, and the name Chad is found in a speech of lyrical heroes who have never belonged to this space or left it (“Lake Chad”). It is shown that one of the main functions of onymic periphrases is to emphasize the social role and status of the character (Theodora and the empress of Byzantium, Gondla and the king of whole Ireland). Sometimes only the context analysis can allow describing certain co-referential proper names as synonymous, for example, Zmeya ‘Serpent’ and Sudya ‘the Judge’ in the play The Tree of Transformation. The materials presented in the paper reflects one of the stages of work on a dictionary of poetonyms in Nikolay Gumilyov’s works. The paper contains brief recommendations regarding the reference area in the dictionary and three abbreviated entries for the names Velzevul ‘Beelzebub,’ Dyavol ‘Devil,’ Lyutshifer ‘Lucifer’ which are frequently used in Gumilyov’s poetic language.

The paper studies official Russian names of rural settlements (comonyms) of the East Kazakhstan region based on toponymic material of three districts: Beskaragai, Borodulikha, and Shemonaikha. The choice of these areas is due to the high proportion of the Russian population and, consequently, Russian place names in the local name system. The author identifies three main toponymic layers: Turkic, Slavic, and German. The latter one offers an insight into the general dynamics of the local toponymic system and some of its historically and politically motivated features. Partial Russification of a number of Turkic place names shows the interaction of subsystems. However, the main attention is paid to the comonyms of Russian origin focusing on their systemic connections, motivation, internal form, and derivational structure. The Slavic substrate allows the authors to illustrate that intralinguistic tendencies and extralinguistic factors create “points of tension” within the toponymic strata that are resolved in one way or another. For example, the current system of rural place names shows a growing tendency for independence and self-sufficiency: the names related to productive and regular word-formation patterns, having close ties in the language and a clear internal form (such as Vladimirovka, Dmitrievka, Ivanovka, Kondratievka, Novopokrovka), become semantically “independent” when used in speech. These are instantly recognized as comonyms by linguistic features even without adding a geographic term (village). It is further planned that the collected material will form the basis of a dictionary of geographical names of the East Kazakhstan region.

Authors: Song Mun-Ku , Jeon Il-Woo , Kang Hyun-Sik
Published: April 2022

PURPOSE: This pilot study aimed to provide descriptive statistics regarding injuries among baseball players in the Korean baseball organization (KBO) league.METHODS: Exposure and injury data were collected from 49 professional baseball players in a single team who participated in official games during the 2021 KBO league season. Injury data included injured body parts, injury mechanisms, injury diagnoses, activities, playing positions, and time-loss (TL). Injury rates (IRs) were calculated using the athletic-exposure (AE) and time-exposure (TE) methods.RESULTS: In total, 158 injuries were reported during the study period. The overall IR was 58.0 per 1,000 AE and 5.3 per 1,000 exposure times (TE). Approximately 68.4% of all injuries were non-TL (NTL) injuries, and which was approximately 2.2 times higher than TL injuries. Among TL injuries, 70.0% accounted for 1 day to less than 1 week, followed by more than 3 weeks (16.0%) and lasting more than 1 week to less than 3 weeks (14.0%) respectively. Trunk and spine were the most frequently injured body parts (21.5%), followed by arms and elbows (12.7%), thighs (11.4%), and feet (8.2%) in order. The majority of the TL injury mechanisms were noncontact (40.4%) and overuse (26.0%) with strain during pitching and base running. The majority of the NTL injury mechanisms were ball contact (73.2%) with contusions during batting and catching.CONCLUSIONS: Professional KBO baseball players experienced a high rate of TL injuries during official games. The majority of TL injury mechanisms were noncontact and overuse, and two-fifths of TL injuries were reported by pitchers and base runners.

RESUMO: Objetivo: Estimar os anos potenciais de vida perdidos por câncer no estado de Mato Grosso, no período de 2000 a 2019, estratificando os dados por sexo, segundo faixas etárias e tipos de câncer. Métodos: Trata-se de um estudo quantitativo, com abordagem ecológica a partir de dados secundários, utilizando-se o indicador anos potenciais de vida perdidos e seus derivados. Resultados: No período analisado, as mortes por câncer em Mato Grosso resultaram em 680.338 anos potenciais de vida perdidos antes dos 80 anos, com variação de 82,5%. Desse total, 52,7% foram atribuídos ao sexo masculino. O peso dos anos potenciais de vida perdidos por câncer antes dos 60 anos foi de 70,9% no sexo masculino e 80,1% entre as mulheres. As taxas de anos potenciais de vida perdidos aumentaram no período estudado e apresentaram valores ligeiramente mais elevados entre os homens. Na análise segundo faixas etárias, as taxas de anos potenciais de vida perdidos também foram maiores entre os homens, exceto entre 30 e 49 anos. Os cânceres de pulmão e linfomas/leucemias resultaram em maiores perdas de anos potenciais de vida entre os homens, e os cânceres de especificidade feminina (mama, colo e corpo do útero e ovário) responderam por 36,26% dos anos potenciais de vida perdidos entre as mulheres, com variabilidade por faixas etárias. Conclusão: Em Mato Grosso, o indicador anos potenciais de vida perdidos por câncer apresentou evolução desfavorável entre 2000 e 2019, com maior prejuízo para o sexo masculino e para a população mais jovem. As leucemias, linfomas e cânceres de pulmão e mama foram os principais responsáveis pelos anos potenciais de vida perdidos.

Livro didático: contradições para o desenvolvimento da imaginação na idade pré-escolar
Authors: Carbonieri Juliana , Magalhães Cassiana
Published: April 2022

Imbuído de contradições, o Edital do Programa Nacional do Livro e do Material Didático (PNLD) 2022 organizou as orientações pedagógicas para a elaboração de livros didáticos para a educação infantil, inclusive para uso das crianças pequenas de 4 e 5 anos de idade no sistema público de ensino. Além de negar a especificidade da primeira etapa da educação básica, o edital busca validar a antecipação da alfabetização para as crianças pequenas. Essa precocidade apresenta riscos para o desenvolvimento psíquico das crianças pré-escolares, em especial no que tange ao desenvolvimento da imaginação. Assim, por meio da análise do Edital PNLD 2022, dos livros didáticos oriundos do mesmo e cotejado com as especificidades do desenvolvimento psíquico no período da idade pré-escolar sob os pressupostos da Teoria Histórico-Cultural, buscamos responder ao seguinte questionamento: Quais os riscos da adoção do livro didático para o desenvolvimento da imaginação das crianças da educação infantil? O critério para definição do livro foi o índice de adoção pelo município de Londrina/PR. Os resultados indicaram que os livros objetivaram os critérios pedagógicos presentes no edital, pressupondo a antecipação da alfabetização e priorizando abusivamente questões de literacia e numeracia. As propostas dos livros didáticos são meramente técnicas, limitadas e de baixa qualidade visual e enunciativa, desconexas da realidade das crianças. Ainda, considerando as premissas para o desenvolvimento da imaginação, o contexto e as imagens presentes nos livros apenas reforçam estereótipos e em nada contribuem com a aquisição ou ampliação de repertórios culturais, necessários para o desenvolvimento dessa função psíquica superior.

A modelagem de equações estruturais com mínimos quadrados parciais (Partial Least Squares Structural Equation Modeling – PLS-SEM) tem sido empregada para modelar construtos hierárquicos em estudos na área de Administração. No entanto, no levantamento realizado nesta pesquisa (em artigos publicados em 2021 nos periódicos core da área de Administração classificados como A2 no Qualis/Capes) e em estudos anteriores foi identificada a inadequação da forma de relatar como as pesquisas foram realizadas. Além disso, da revisão da literatura, percebeu-se a ausência de diretrizes claras, sobretudo em relação a forma de mensuração do componente de ordem superior de construtos hierárquicos. Como resposta a isso, apresenta-se neste artigo orientações sobre como especificar, estimar e avaliar modelos de componentes hierárquicos em PLS-SEM, mais especificamente para construtos de segunda ordem, e também sobre como relatar a configuração utilizada e os resultados obtidos. Essas orietações podem apoiar autores a aumentar a transparência dos procedimentos metodológicos dos seus estudos, bem como podem auxiliar editores e revisores no desenvolvimento de questões específicas que podem ser aprimoradas em processos de arbitragem científica, contribuindo, dessa forma, para confiabilidade do conhecimento acadêmico produzido.

Grid nanoindentation and quantitative X-ray diffraction are employed to provide quantitative information on phase constituents of nanoscale pozzolan-containing ultra-high-performance concrete (UHPC). Three UHPC samples containing nanoscale pozzolan and cured with and without microwave energy are investigated. The volume fraction of each phase constituent is independently evaluated using both techniques: nanoindentation (NI) and quantitative X-ray diffraction (QXRD). For the NI, the volumes have been evaluated by taking into account the thresholds characterising the phase constituents. The NI could assess phase mixtures or composites rather than single phases. The microwave-cured samples (CMW and CPMW) contain in total more hydration products that the sample that was not cured with microwave energy (C000). In all three samples, a nanocomposite (C–S–H/CHnm) consisting of high-density (HD) calcium silicate hydrate (C–S–H) and nanoscale portlandite (CH) is included, and its amount is more than double for the pressure-compacted and microwave-cured sample (CPMW). The heat curing by microwave energy together with the very low amount of water and restriction of the available space for hydration products, favour the formation of the nanocomposite (C–S–H/CHnm) in the CPMW sample.

Here the authors report a versatile and strong underwater adhesive that was inspired by the chemical features of mussel foot proteins. A random copolymer (poly(N-(3,4-dihydroxyphenethyl)methacrylamide-co-methacryloxyethyltrimethyl ammonium chloride-co-acrylamide) (PDMA)–Tf2N) was prepared that contained side-chain catechol groups and quaternary ammonium cations that were ion-paired with bis(trifluoromethane-sulfonyl)imide anion (Tf2N−). After dissolving PDMA–Tf2N and poly(acrylic acid) in dimethyl sulfoxide, a polyelectrolyte complex coacervate adhesive (P2) could be formed, which could be triggered through solvent exchange. P2 exhibited outstanding underwater shear strength to various substrate surfaces. After a critical curing time (t s = 10 min), the adhesion strength of P2 to glass increased sharply up to 187.298 kPa (t s = 40 min).

Investigating the interaction between structures and their elastic foundations is essential in structures with elastic support conditions, such as buried pipelines and piles. Research investigation was carried out to find the frequency of a buried structure simulated by Euler–Bernoulli beam equations, with distributed damping and general boundary conditions on an elastic foundation. The elastic bed was modelled by a linear spring, and boundary conditions were changeable at two ends of the beam's support with variations in the stiffness of transitional and rotational springs. The differential transformation method (DTM) was then used to solve the equations by correlating the function and its derivatives. The frequency of the structure was obtained for various damping and stiffness values. The increase in the stiffness of the elastic support and the decrease in damping led to a higher frequency. The results of DTM agreed with the results of the exact method.
Embodied carbon, embodied energy and renewable energy: a review of environmental product declarations
Authors: Anderson Jane , Moncaster Alice
Published: April 2022

Environmental product declarations (EPD) to EN 15804 provide information about the embodied carbon dioxide of construction products – their life cycle greenhouse gas emissions – alongside reporting the use of renewable and non-renewable primary energy and secondary fuels, among the other environmental indicators. As the number of EPD to EN 15804 increases, they become a useful data resource to consider these impacts. In moving towards a reduction in the embodied carbon of products, it is necessary to use renewable energy resources efficiently to allow the transition to net zero; this is because of the increasing demands on renewable energy to decarbonise industry, transport and domestic energy consumption and the limited capacity to expand renewable generation. This paper reviews published EPD data for structural and reinforcing steels, cement, bricks and structural timber products, and considers, for the cradle to gate ‘product’ life cycle stage, exploring the relationship of embodied carbon with embodied energy (total energy used), the balance of renewable and non-renewable energy, and the efficient use of energy. It is found, for bricks and timber, that EPD show products that use a greater percentage of renewable energy have higher embodied energy, suggesting a less efficient use of renewable energy for these products.
Quasi-Resonant Half-Wave Buck Converter with Non-Isolated High Side Switching Techniques
Authors: GÖRDÜK Burak , TOPUZ Elif , YILDIRIM Deniz
Published: April 2022

Power density of the power converters became one of the most important parameters in many applications. Power density is increased by reducing the losses through use of better performing components and circuit topologies. It can be increased further by reducing the size of filter components through increasing the switching frequency. In hard-switching converters however, losses due to switching will eventually render this method not applicable. Instead, resonant converters are utilized in many high-frequency switched power supplies. Soft-switching feature of these converters provide increased efficiency due to decreased switching losses. Such converters exploit the resonance of the specific inductors and capacitors in the circuit called as resonant tank elements. Resonance behavior is used in order to eliminate turn-on or turn-off losses. Existing power converter topologies can be modified to create the resonance during switching period. Such converters are called as quasi-resonant converters. This paper presents analysis and design of Zero Current Switching (ZCS) half-wave quasi-resonant buck converters. In this topology, high-side switching is required. Two different non-isolated high-side switching techniques are utilized. Experimental results are obtained for light load to full load operation. Both techniques are compared in detail.

Authors: KEPEKÇİ Haydar , ASLAN Erman
Published: April 2022

Three different geometries have been used in this study, which investigated the effect of inclination angle on convective heat transfer in corrugated channels. The corrugated channel geometries used have inclination angles of 30°, 45°, and 60°. The finite volume method has been used in the study with numerical methods. k-ω, SST, and transition SST have been used as turbulence models. The mesh file used in the analysis consists of 192000 cells. The results obtained from the calculations using a corrugated channel with a 30° inclination angle have been compared with the experimental data. As a result of this comparison, the turbulence model to be used for this study has been determined as SST. SST turbulence model has been used in the analyzes made using a corrugated channel with 45° and 60° inclination angles and the results have been compared with each other. The Reynolds number ranges from 2225 to 7380. The Nusselt number and friction factor have been calculated using the data obtained as a result of the analysis. Based on the calculated values, it has been determined that the heat transfer increases as the angle of inclination increases in the corrugated channels. It has been also observed that the Nusselt number increased as the Reynolds number increased. It has been also seen that the analyzes for high Reynolds number gave results closer to the experimental data.

The COVID-19 pandemic has had social and economic impacts on every country in the world and has caused significant changes in human nutrition. In this study, changes in the food supply chain and consumption practices before and after the controlled normalization of people living in Turkey were examined, with a survey of 1087 people. The results revealed that people focused on a healthier diet during the pandemic. The increase in dietary supplement consumption has not been too high, only 11% of people started to take dietary supplements, but fast food consumption had a sharp fall. The packaging has become more critical. People continued to use take-out services from supermarkets and fast-food restaurants. Although normalization has begun, most of them (90%) reduced or did not think about eating out until COVID-19 will over. This study revealed the effects of the pandemic on human nutrition and showed which direction the food supply should go.
