Authors: Zhang Qian , Yang Jeng-Sheng , Qi Guangyue , Ma Yifei , Zhang Xuyang
Published: September 2024

This study assessed the effect of routine chiropractic care combined with a three-month strength and conditioning program on the physical performance of adolescent basketball players. Thirty-one male athletes, aged 16-19, from elite Chinese national basketball camps, were divided into experimental and control groups. All subjects received cervical adjustment one time per week done by a team chiropractor. The program aimed to enhance agility, muscular strength, endurance, and speed through professional training. Measurements were taken at baseline, at six weeks, and after twelve weeks, using tests such as the ¾ court sprint, box agility, 1RM back squat, 1RM bench press, 65kg bench press for maximum reps, and 17-line shuttle run. The experimental group showed significant improvements in all metrics except the box agility test, while the control group exhibited fewer substantial changes. Results indicate that structured strength and conditioning programs combined with chiropractic adjustment significantly enhance adolescent athletes’ physical performance. The level of significance was set at p < 0.05. The study concludes that consistent chiropractic care and professionally supervised training are beneficial for adolescent athletes’ development, suggesting the integration of such programs into training routines for adolescent athletes to improve their physical capabilities and minimize injury risks.
Linguistic Manifestation of Concept of HEALTH in Contemporary Domestic Discursive Practices (Newspaper Corpora)
Authors: Radbil T. B.
Published: September 2024

This study addresses the issue of the linguistic explication of the concept of HEALTH within contemporary domestic media discourse. An investigation has been conducted into the functioning of the conceptual name — the lexeme ‘health’ — through linguistic material derived from contexts extracted from newspaper corpora within the National Corpus of the Russian Language. A corpus-based discursive analysis methodology was employed. Conceptual-metaphorical models that enrich the meaning of the concept and expand its semantic scope have been identified. It is demonstrated that the semantic transformations of the lexeme ‘health’ in its discursive realization reveal reflections on the understanding of the abstract concept of HEALTH as a resource, substance, physical object, mechanism, container, living entity, and more. It has been established that the augmentation of the semantic volume of the concept in contexts of attributive and genitive compatibility illustrates the dissemination of notions regarding health as a normal state or functioning of various entities across a wide array of spiritual, moral, psychological, emotional, social, political, economic, financial, industrial, natural, and cultural domains, including the operational sphere of devices, household items, instruments, and mechanisms. The study concludes with the assertion that the analyzed concept possesses a representative value potential linked to the cognitive dominance of normativity.
Hybrid ‘sledom’ [follows] in Area of Interaction of Nouns and Adverbs: Semantics and Grammar
Authors: Shigurov V. V. , Shigurova T. A.
Published: September 2024

This article presents the results of a study on the process and outcome of the stepwise adverbialization of the instrumental case of nouns in the Russian. The relevance of this work is underscored by the attention to the interaction between grammatical and semantic aspects within lexical units subject to transposition at the level of parts of speech. The aim of the article is to elucidate the specifics of hybrid structures formed as a result of the functional adverbialization of nouns in the instrumental case. The material used consists of contexts from the Russian National Corpus featuring substantive word forms like ‘sledom’, demonstrating various stages of adverbialization. An interdisciplinary approach is employed, utilizing methods of oppositional analysis, indexing, linguistic experimentation, as well as elements of componential and distributional analysis. Using the word form ‘sledom’ as a case study, the primary stages of adverbial transposition of nouns in Russian are identified. The analysis reveals that within the hybrid zone, the word form ‘sledom’ exhibits 55 % correspondence with the features of its original noun (‘sled’) and 60 % correspondence with the characteristics of a core adverb (‘sledom’). Lexicalization of the word form at this stage of adverbialization is not observed; it continues to function within the semantic domain of the original substantive lexeme. The significance of this research lies in its contribution to the development of a general theory of transitivity and syncretism in the grammatical structure of language, as well as the potential application of the proposed methods of oppositional analysis and indexing in studying other types of transpositional transformations within the system of parts of speech in the Russian.
Integration of Blogging and Children’s Television: Issues and Perspectives
Authors: Rebrova A. D.
Published: September 2024

The issue of integrating blogging practices into children’s television programs is considered as one of the factors for popularizing the latter among the younger generation. It is noted that children prefer entertaining online resources. It is shown that parents are concerned about their children’s immersion in the virtual sphere, the difficulty of controlling the information received, and the influence of popular bloggers on shaping children’s worldview. It is pointed out that resources for children under 13 are widely available on the Internet and television, while there are no such specialized resources for teenagers, particularly on central television. Meanwhile, the government has adopted a program document for the development of education for children and adolescents, in which a television channel for the latter could provide certain assistance. The author of the article proposes a working concept for a children’s television channel for teenagers, which integrates blogging practices. It is concluded that the synthesis of educational, developmental, and entertainment functions, involving child bloggers and the target audience in program development and hosting, organizing active feedback with the audience, and other factors will contribute to the channel’s success, provided there is government interest.
“Floral Ornament of Reality”: Flowers in Worldview of E. T. A. Hoffmann and N. A. Polevoy
Authors: Ilchenko N. M. , Chernysheva E. G.
Published: September 2024

The relevance of this study is grounded in the scholarly significance of the issue of Russian-German literary connections as a crucial factor in intercultural interaction. This article analyzes works in which the authors articulate a mystical sense of nature, based on the natural philosophical ideas of F. Schelling. The focus of the investigation is the national distinctiveness of Romanticism, manifested in the peculiarities of nature perception, particularly floral imagery. It is demonstrated that the Romantic writers of Germany and Russia perceived love, within the value-emotional framework of the Romantic universe, as a mystical feeling that enables one to penetrate the mysterious forces of nature. The floral motifs within the works contribute an additional allegorical meaning to the artistic worlds of E. T. A. Hoffmann and N. A. Polevoy. The “floral background” of the characters in the analyzed texts (the tulip Gamachea, the thistle Pepush, the bride Tis — Little Rose; Emma — cornflower; Italy — “poor forget-me-not,” among others) establishes a symbolic language of nature. Attention is also given to motifs traditional to German literature: yearning, soul affinity, reminiscence of a “different world,” and the union of lovers in death, which are reflected in the examined works of Russian literature. The novelty of this research lies in its consideration of N. A. Polevoy’s dialogue with the German literary tradition represented by E. T. A. Hoffmann as a result of his philosophical and poetic explorations.
Police Oversight of Legality in Railway Freight Transport in Russian Empire During World War I
Authors: Kolpakov P. A.
Published: September 2024

This article analyzes the activities of the gendarmerie railway police in ensuring compliance by freight carriers with prohibitions and restrictions on the export of certain raw materials and goods during World War I. Based on documentary materials, it reveals the content of the state policy of the Russian Empire regarding measures to halt the supply of essential resources to the Central Powers’ armies. The study of the administrative documentation of the railway police indicates that particular attention was paid to monitoring freight transport at border stations. The issue of police support for the stable functioning of railways under wartime conditions is explored. Gendarmerie officers facilitated the prioritization of military cargo movement along steel corridors. A critical responsibility of the gendarmerie was uncovering collusion among railway employees and shippers to manipulate train speeds for illicit speculative profit amid commodity shortages. The study concludes that the gendarmerie railway police played a significant role in overseeing the legality of freight transport during World War I. However, amid the disorganization of state mechanisms and deepening crises in Russian society, ensuring uninterrupted and effective railway operations proved impossible.
National Conflicts in North Caucasus: Origins and Resolution
Authors: Sevinj M. S.
Published: September 2024

This article examines the causes and consequences of national conflicts in the North Caucasus. It addresses issues related to the sources of ethnic conflicts in contemporary times. The significance of the North Caucasus as a bridge connecting north to south and west to east is emphasized, highlighting its immense importance for the Russian Federation. From a geostrategic perspective, this region serves as a gateway to Central Asia while also providing access to Western markets. The paper pays particular attention to events that have transpired since the late 1980s in the Caucasus, where some of the most acute ethnopolitical conflicts and wars have occurred. Six out of eight armed ethnopolitical civil conflicts in the post-Soviet space unfolded in this region. The article raises the issue that, as a result of these events, the Caucasian region has become a battleground for separatist organizations within the post-Soviet context. Armed conflicts have led to numerous human casualties, material losses, economic downturns, and other tragedies. Based on the materials studied, it is concluded that ethnic conflicts are diverse in their manifestations. The conditions for the politicization of ethnic conflicts in the North Caucasus are also explored.
Methods of Translating Names of Material Culture Objects into Russian (Translation of Yuan Ke’s “Myths of Ancient China”)
Authors: Gu Junling , Zhang Xiaoyu , Pogrebnyak Yu. V.
Published: September 2024

This article analyzes the existing translation of Yuan Ke’s “Myths of Ancient China” (1960), carried out by E. I. Lubo-Lesnichenko and E. V. Puzitsky (1965), focusing on the strategies employed by the translators in conveying Chinese names into Russian in instances of cultural gaps. The aim of the article is to summarize the strategies adhered to by the authors in translating Chinese mythological narratives and to identify the most suitable methods for rendering names of material culture objects into Russian. An assessment is provided regarding the accuracy of translations of fragments of myths that mention concepts such as “tripod,” “jade hairpin,” “jade tablet,” “Jai-gong, Palace of Abstinence,” and others. The analysis reveals that the methods utilized by translators of ancient Chinese myths primarily include phonetic transliteration, literal translation, addition, omission, and annotation. However, the application of these strategies sometimes results in distortion and omission of the original information. This article proposes translational strategies, within the framework of foreignization, that should be adhered to when translating Chinese mythological narratives: addition, omission, transfer, substitution, division, combination, and transliteration.

Authors: Szabó-Szentgróti Gábor , Walter Virág , Végvári Bence
Published: September 2024

The technological development and the rise of artificial intelligence are driving a significant transformation of the labor market. The technological unemployment predicted by Keynes poses challenges for the global labor market that require new solutions. Basic income research has become a significant field of study, attracting attention from various disciplines such as political science, law, economics, and sociology. The aim of this paper is to explore on the basis of a literature review, what factors influence the support for basic income among the population. A systematic literature review based on the Web of Science and Scopus databases, after screening 2623 publications, identified 23 articles that contained findings relevant to the research question. A significant number of authors (12/23) analyzed data from the same source, the European Social Survey 2016 (ESS Round 8, 2020), conducted in 2016, first published in 2017 and updated several times since then. The paper shows that the study of the topic has a strong European focus. The social, economic, social and cultural diversity of European countries makes these studies important from a European and EU perspective, but from an international perspective, further research on the topic is needed.

Authors: Wang Guoxian , Jang Jungsik , Shin Jinwoo , Li Dongsheng
Published: September 2024

This paper studies the product language construction of the twisted porcelain cultural heritage. Through field research, we collected and sorted out samples of twisted porcelain products, explored the product language characteristics of twisted porcelain from multiple aspects such as production process, product shape, and product color, interpreted cultural value, captured potential connotations, extracted representative words from user comments, quantified the relationship between users and twisted porcelain culture, realized the construction and transmission of traditional cultural language information, conveyed the traditional cultural information of the product to users, and promoted the sustainable dissemination and development of this cultural heritage. The research results show that after mining and extraction at the level of twisted porcelain characteristics, the core language constructs the cultural expression of twisted porcelain products, which is more in line with the needs of the market and users, and has the potential to be developed and disseminated using the language generation of cultural heritage products.
Grade IV gastric ulceration, pyloric aplasia, and an ectopic duodenal papilla in a 13-year-old Quarter Horse gelding evaluated for recurrent colic
Authors: Barton Charlotte K. , True Alex , Fenn Melissa , Thampi Parvathy , Watson Allison , Smanik Lauren E.
Published: September 2024

OBJECTIVE

The objective of this Case Report was to describe the clinical manifestation and postmortem findings of a horse evaluated for recurrent colic diagnosed with pyloric aplasia and an ectopic duodenal papilla.

ANIMAL

13-year-old Quarter Horse gelding.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

The horse was presented to a referral center for signs of colic that were unresponsive to management on the farm. No abnormalities were noted on rectal palpation; however, upon passage of a nasogastric tube, 31 L of net gastric reflux was obtained. Gastroscopy noted grade IV squamous ulceration and moderate glandular ulceration, severe gastric dilatation, an abnormally positioned gastric outflow tract, and an ectopic duodenal papilla leaking bile-like fluid directly into the stomach.

TREATMENT AND OUTCOME

The horse was initially treated with gastroprotectants, promotility agents, and dietary modifications. Following treatment failure and repeated episodes of colic with increasing severity, the horse was euthanized and a necropsy performed. At necropsy, it was confirmed that the aboral aspect of the stomach formed a dilated pouch and continued directly into the proximal duodenum with no discernible pyloric sphincter. The area of the pylorus was delineated by a faint indentation. The ectopic duodenal papilla was traced to the liver.

CLINICAL RELEVANCE

Congenital gastric abnormalities, even in adult horses, should be considered as differential diagnoses when investigating horses presenting with a history of chronic colic. Neither pyloric aplasia nor an ectopic duodenal papilla have been described in the equine literature, and this Case Report raises awareness of the presence of such malformations and their manifestations.
Subclinical bacteriuria is nonprogressive but persistent in dogs four years of age or older recruited from a small animal primary care setting
Authors: Frey Erin , Rhea Sarah , Jacob Megan , Vaden Shelly , Kendall Allison , Bennett Katelyn , Johnson Brianna
Published: September 2024

OBJECTIVE

To evaluate clinical and microbial outcomes in dogs with untreated subclinical bacteriuria (SB) through longitudinal follow-up.

METHODS

Between February 24, 2022, and July 7, 2023, healthy client-owned dogs ≥ 4 years old with no evidence of lower urinary tract signs (LUTS) were recruited for a longitudinal, prospective study. Phase 1 dogs with SB were followed for 28 days to document comorbidities and microbiological findings (ie, urinalysis, urine culture, and fimH gene in Escherichia coli isolates). Phase 1 participants enrolled in phase 2 were followed for at least an additional 120 days.

RESULTS

The prevalence of SB was 11% (11 of 99), and all were female spayed. Of those with SB, 6 (55%) were followed for a median of 238 days; 91% (10 of 11) of phase 1 dogs and 67% (4 of 6) of phase 2 dogs had persistent bacteriuria, and 1 developed pyelonephritis 299 days after enrollment. Most dogs had E coli (8 of 11 [73%]), all of which contained the fimH gene. No change in antimicrobial susceptibility was noted during follow-up.

CONCLUSIONS

SB is generally nonprogressive and can persist for months after diagnosis. Patients with SB were more likely to be female, but no difference related to age, weight, or life stage was found. The presence of fimH, previously associated with biofilm, was negatively correlated with antimicrobial resistance.

CLINICAL RELEVANCE

For dogs with SB that are otherwise healthy, avoidance of systemic antimicrobials is warranted. For dogs with additional comorbidities, which might not be accompanied by, for example, pyelonephritis, or preclude the demonstration of LUTS, veterinarians should review the medical history and consider additional diagnostic testing.

Red raspberries are among the most significant wild edible fruits (WEFs) in Türkiye, thriving in cold to warm temperate regions across the country. This study focuses on 11 wild red raspberry ecotypes sampled from the Northern Anatolia region, examining their sensory, biochemical and antioxidant properties. Sensory analysis was used to compare ecotypes based on aroma, taste and juiciness. Biochemical assessments included soluble solid content (SSC), vitamin C amount, organic acids, total anthocyanins (TA), total phenolic content (TPC), total flavonoid content and total antioxidant capacity. The Ferric Reducing Antioxidant Power (FRAP) assay measured antioxidant capacity. Despite similar growing conditions, significant variations were observed among ecotypes and across years. In the first year, fruit weights ranged from 1.04 g to 1.33 g, and in the second year, they ranged from 0.97 g to 1.27 g. Fruit chroma values ranged between 26.11 and 33.70 in 2021, and 23.17 and 30.19 in 2022. Vitamin C exhibited considerable variability, ranging from 29.3 mg · 100 g−1 to 44.4 mg · 100 g−1 across ecotypes and years. TPC, total anthocyanin content (TAC) and total flavonoid content ranged from 164 mg to 390 mg gallic acid equivalent (GAE) · 100 g−1, 17.3 mg to 33.2 mg cyanidin-3-glucoside equivalent · 100 g−1 and 10.3 mg to 17.6 mg quercetin equivalent (QE) · 100 g−1, respectively, in both years. Citric acid emerged as the dominant organic acid across all ecotypes. Notably, the ecotypes V-4, V-8, V-3 and V-10 showcased larger, more appealing fruits suitable for fresh consumption, whereas V-3 and V-5 presented sweeter fruits ideal for processing. Additionally, the ecotypes V-6, V-7 and V-11 displayed higher levels of health-promoting compounds, such as TPC and antioxidant capacity, suggesting their potential as functional foods and valuable sources of natural antioxidants in the future.

Published: September 2024

Bioelectrical impedance techniques have been useful in various applications, including body composition analysis, impedance plethysmography, impedance cardiography, lung ventilation, perfusion, and tissue characterization. Electrical impedance methods have also been useful in characterizing different foods like meat, fruits, and beverages. However, the temperature of tissue samples can change their dielectric properties, affecting their impedance. This research investigated the effects of temperature on the impedance of various biological tissues over the frequency range of 10 Hz to 5 MHz. Freshly excised animal tissues (lamb, cow, chicken), fish, fruits, and plants were considered as biological samples. The samples were placed in a test cell and submerged in a water bath heated by a hot plate to vary the temperature. Impedance measurements were conducted using a bioimpedance spectrometer in 2 °C steps within the temperature range of 20 °C to 50 °C. Impedance values decreased with increased temperature across all measurement frequencies for all biological samples. Curve fitting indicated that impedance decreased linearly with temperature, with a mean correlation coefficient of 0.972 for all samples. For all biological samples under investigation, the relative impedance change ranged from −0.58% to −2.27% per °C, with a mean and standard deviation of (−1.42±0.34) %/°C. On average, animal samples exhibited a higher relative temperature coefficient of −1.56% per °C (±0.41) across the frequency range, compared to −1.31% per °C (±0.26) for fruit and vegetable samples. Additionally, the relative temperature coefficient values were generally higher at lower frequencies than at higher frequencies. The findings of this research can be valuable for studies or biomedical applications involving variable tissue temperatures.
Микрофинансовая деятельность в России: институциональные пустоты и непродуктивное предпринимательство
Authors: Ветлугин Денис Дмитриевич
Published: September 2024

This article considers the relationship between the quality of the institutional environment and the development of microfinance activities, presents an overview of empirical data that allow us to record the impact of the microfinance institution in the Russian Federation on the socio-economic processes of society in the context of entrepreneurial structures functioning within the framework of this institution. The aim of the study was to identify the socio-economic effects of the microfinance institution, as well as to identify the reasons for the unproductivity of microfinanceorganizations (MFOs) as entrepreneurial structures, from the point of view of public welfare. The paper shows that the presence of institutional voids stimulated the development of unproductive type of entrepreneurship — commercial microfinance activities. The main institutional reasons for the inefficiency of private MFOs were identified, and the “shift of their mission” and its manifestations were recorded. It is shown that a significant problem in the microfinance market is the actual absence of current control by the regulator over the activities of MFOs as hybrid organizations with a “dual mission”, as well as institutional rules, in particular, incentives that determine by what means these organizations can strive to achieve their goals. This allows MFOs to maximize profits while ignoring their social function.
Genetic and clinical characterization of Niemann-Pick disease type C with homozygous NPC1 gene mutation: insights from whole exome sequencing and advanced neuroimaging of two familial cases
Authors: Karim Hajira , Oria Lima , Elmas Muhsin
Published: September 2024

Background: Niemann-Pick disease Type C (NPC) is a rare genetic lipid storage disorder characterized by heterogeneous clinical presentations primarily affecting the neurological and visceral systems. This study aims to elucidate the clinical manifestations, radiological findings, and genetic characteristics of NPC, emphasizing the implications of familial aggregation and consanguinity.
Case Presentation: We present two cases from a single family, detailing the clinical progression, radiological findings, and genetic mutations. Case 1 involves a 39-year-old male exhibiting symptoms such as dysarthria, cerebellar ataxia, and progressive neurological decline over eight years. Case 2, a relative aged five, displays similar early-onset neurological symptoms. Both cases demonstrate significant cerebellar atrophy on MRI and share a familial NPC1 gene mutation, suggesting a hereditary pattern influenced by consanguineous relationships. Whole Exome Sequencing identified a pathogenic homozygous mutation in the NPC1 gene, confirming the diagnosis of NPC. This finding underscores the genetic basis of the disease and highlights the role of familial genetics in its pathogenesis.
Conclusion: These cases underscore the critical role of genetic testing, particularly whole exome sequencing, in diagnosing NPC, which can often present with diverse clinical symptoms. The familial clustering observed also draws attention to the genetic counseling needs in populations with high rates of consanguinity, emphasizing the importance of community genetic studies to understand and manage such rare disorders.
Strategies and Challenges in English to Chinese Translation of Selected Song Lyrics
Authors: Amini Mansour , Ooi Faith Fang Xi , Choo Sue Anne Xuan-En , Saffari Narges , Lee Kam-Fong , Ravindran Latha
Published: September 2024

The translation of song lyrics is challenging for translators primarily due to the intricate poetic and musical elements, which often compel them to employ specific strategies for effective translation. This study was an attempt to investigate the translation strategies in selected translated movie song lyrics and explore the challenges in translating the lyrics. In this qualitative study, the songs were purposefully selected from “Mulan” (1998) and “Aladdin” (2019) movies. Low’s (2013) translation strategies were applied during the process of translation. The “Translation” (transfer of material with a reasonably high degree of semantic fidelity), and “Replacement” (a re-creation of text by only preserving the music element) strategies were found as the common strategies in the translation of song lyrics. The use of a replacement strategy could be due to technical difficulties in translating songs, such as the constraint of rhythm, hence a total replacement of meanings to match the rhythm of the song. A significant challenge in translating song lyrics from English to Chinese was in translating the concept of face-saving, which is an eminent process in social interactions in Chinese culture. It was concluded that the use of a translation strategy depended on the lyrics, translators’ creativity, melody, rhyme, and the differences between the languages and cultures, while the “skopos”, i.e., the correspondence of aim/purpose in the source and target cultures should play the key role.
Inverse-Kinematics Steering Laws for Double-Gimbal Scissored-Pair Control Moment Gyros
Authors: Kojima Hirohisa , Kawamoto Ryo , Keshtkar Sajjad
Published: September 2024

The generalized singularity robust inverse steering law (GSRISL) is widely used to avoid singularity problems in control moment gyroscopes (CMGs). However, GSRISL tends to generate perturbation torques near singularities, which hinder highly accurate attitude tracking control. Model predictive steering control can eliminate the necessity of considering singularities, but its implementation in satellites remains challenging because of its high computational cost. Therefore, the development of a steering law that avoids explicit consideration of internal singularities and costly calculations is critical. The inverse-kinematics steering law (IKSL) is one such law removing the need for the calculation of the inverse matrix. The double-gimbal scissored-pair CMG (DGSPCMG) addresses the singularity problem as it does not have internal singularities except along the outer gimbal axis. To enhance the attitude control by removing the need for the calculation of the inverse matrix, this study proposes the combining of IKSL with DGSPCMG. Additionally, to mitigate the risk of gimbal mechanical failure, the IKSL for inner or outer gimbal axes failure was designed by relaxing the identical steering constraint of the scissored-pair gimbal angles. Numerical simulations were performed to evaluate the effectiveness of the combination of IKSL and DGSPCMG in terms of settling time and maneuvering axis accuracy.
Angles-Only Cooperative Local Catalog Maintenance of Close-Proximity Satellite Systems
Authors: Hays Christopher W. , Henderson Troy , Miller Kristina , Phillips Sean , Soderlund Alexander
Published: September 2024

In space mission sets like on-orbit servicing and manufacturing, agents in close proximity may operate too close to yield resolved localization solutions to operators. This requires that the system maintain a catalog of its local neighborhood; however, this imposes a large burden on each agent to update its catalog. This paper considers the case of multiple satellites each maintaining their catalog. Specifically, this paper considers the case of numerous noncooperative objects and a collection of agents operating in the same local environment. The goal of each agent is to maintain their catalog of all bodies (objects and agents) within this neighborhood through onboard angles-only measurements and cooperative communication with the other agents. A central supervisor selects the target body for each agent, a local controller tracks the selected target body for each agent, and a local estimator coalesces both an agent’s measurements and state estimates provided by neighboring agents within the communication graph. Numerical results are provided to demonstrate the supervisor’s ability to select an appropriate target subject to an uncertainty threshold, the controller’s ability to track the selected target, and the estimator’s ability to maintain an accurate and precise estimate of each of the bodies in the local environment.
Fixed- and Free-Mode Flutter Derivatives During Aeroelastic Optimization
Authors: Stanford Bret K. , Thelen Andrew S. , Jacobson Kevin E.
Published: September 2024

Aeroelastic flutter design derivatives may be approximated by ignoring the sensitivity of the structural mode shapes. This fixed-mode derivative is less expensive to compute than the exact free-mode derivative (which accommodates the mode shape dependency) but also may provide inaccurate sensitivities for optimization. This work formulates both fixed- and free-mode flutter derivatives and demonstrates the conditions under which they are equivalent. Two different types of fixed-mode derivatives are also developed in this work. Using a cantilevered-plate demonstration problem with both shape and sizing design parameters, the accuracy of the free-mode derivative and the two fixed-mode derivatives is demonstrated via gradient-based optimization.

Library as a Participant in the Utilization of Research Results
Authors: Lavrik Olga L.
Published: September 2024

One of the problems existing in science is the use of scientific research results in practice. The aims of the article are to show, through a review of foreign literature and the results of a survey of domestic experts in the field of library science and librarianship, the reasons for the disconnection between science and practice, as well as to identify the steps necessary for practice to benefit from research. The problem is posed from the perspective of post-non-classical science as applied to library science and librarianship. The reasons for the lack of transfer of scientific results into practice, identified by foreign authors, are given. The rating of the reasons noted by domestic experts, who put the technical backwardness of libraries and the lack of motivation of specialists to implement the results of scientific work in practice in the first place, is presented. Various options for solving the problem of non-use of scientific results in practice are analyzed and evaluated. Ways to eliminate the problem: using different ways to attract and expand the participation of practitioners in theoretical research, increasing their research activity; dissemination of research results, including overcoming the deficit of publications and increasing their number written by practitioners; continuing professional education. It is concluded that if we proceed from post-nonclassical science, it becomes clear why the results of scientific research conducted on the basis of one library cannot be applied to another: the peculiarities of one library are not absolute, they depend on existing situational relationships. The non-use of modern scientific results in librarianship is also related to the dependence of science on the socio-cultural environment and the inclusion of value attitudes. Among the ways to bridge this gap are the following: creating special publications for practitioners, webinars, face-to-face meetings and conversations between researchers and practitioners. One method of improving the link between research and practice is to include research reports (research reviews) in newsletters, various periodicals often read by practitioners.
Enabling a Smooth Transition: Responsible Chemistry Competencies for the European Green Deal
Authors: Mehlich Jan
Published: September 2024

Chemists are a vital part of the research and innovation (R&I) landscape. With their expertise, they shape progress and, thus, society. In order to live up to this responsibility, it is suggested to prepare young chemists for their future role as innovators with proper training. Here, it is important to go beyond the good scientific practice dimension of research integrity and add discourse performance and value assessments to the class outline of a “responsible chemistry” course. This becomes especially relevant in view of changing demands on chemical research and innovation as envisioned by the European Green Deal through its Horizon Europe funding scheme. This paper outlines the necessity of preparing chemists for the requirements of a green transition R&I policy and shows what that would mean for “ethics in chemistry” education.
The Multiple Challenges of Handling Scientific Integrity in the Swiss Higher Education System
Authors: Leumann Christian J.
Published: September 2024

Scientific integrity is the most important aspect that higher education institutions have to take care of, as it conveys credibility and acceptance of science to the public. Although science has a very powerful built-in self-regulation process for detecting and correcting scientific misconduct, there is a need for clear guidelines that have to be adapted on regular intervals to the rapidly changing world caused by scientific developments themselves. Outlined here are recent advances in how Switzerland increases awareness and transparency of scientific misconduct and how it handles cases of misconduct to improve the quality of science.

В настоящее время при разработке антифрикционных материалов актуальным становится использование полимерныхкомпозиционныхматериалов (ПКМ) на основе полимерной матрицы с самосмазывающимися свойствами. Антифрикционные материалы находят широкое применение в разных узлах трения техники и технологического оборудования. В качестве основы ПКМ отлично показывает себя политетрафторэтилен (ПТФЭ), который обладает широкимдиапазономрабочих температур и низкимкоэффициентомтрения. Однако ПТФЭ имеет недостатки в виде высокой скорости массового изнашивания и хладотекучести. Для устранения недостатков в полимер вводят различные наполнители, в особенности дисперсные наноразмерные частицы, так как они показывают существенное влияние на эксплуатационные характеристики. В данной работе в качестве наполнителя был использован наноразмерный оксид цинка, который предварительно подвергнут ультразвуковому воздействию. Исследованы физико-механические, триботехнические свойства и термодинамические параметры ПКМ. Триботехнические исследования показали повышение износостойкости ПКМ при сохранении низкого значения их коэффициента трения. Поверхность трения материаловисследовали методом ИК-спектроскопии, где выявлено протекание трибохимических реакций. Разработанные материалы благодаря улучшенным триботехническим свойствам могут найти применение в качестве уплотнителей в узлах трения машин и техники.

Currently, in the development of antifriction materials, the use of polymer composite materials (PCM) based on a polymer matrix with self-lubricating properties is becoming relevant. Antifriction materials are widely used in various friction units of machinery and technological equipment. Polytetrafluoroethylene (PTFE), which has a wide range of operating temperatures and a low coefficient of friction, performs well as a PCM base. However, PTFE has the disadvantages of high mass wear rates and cold flow. To eliminate the shortcomings, various fillers are introduced into the polymer, especially dispersed nano-sized particles, as they have a significant impact on performance characteristics. In this work, nanosized zinc oxide was used as a filler, which was previously subjected to ultrasonic treatment. The mechanical, tribological properties and thermodynamic parameters of PCM have been studied. Tribological studies have shown an increase in the wear resistance of PCM while maintaining a low value of their friction coefficient. The friction surface of the materials was studied by IR spectroscopy, where the occurrence of tribochemical reactions was revealed. Thanks to their improved tribological properties, the developed materials can be used as seals in friction units of machines and equipment.

Novel Coronavirus Infection (COVID-19) is a rapidly spreading pandemic disease worldwide that has created significant public health challenges. According to statistics, about 5-12% of patients with COVID-19 need hospitalization and treatment in intensive care units. Given the most common respiratory system injury, most intensive care patients require oxygen therapy and long-term artificial lung ventilation (ALV). Post-intubation and post-tracheostomy tracheal stenosis is an iatrogenic complication that occurs in 10–22% of patients after prolonged mechanical ventilation among the entire patient pool, while the frequency of cicatricial tracheal stenosis after a complicated course of COVID-19 coronavirus infection remains unknown. This paper presents the features of diagnosis and surgical treatment.

По статистике, около 5–12% пациентов с COVID-19 нуждаются в госпитализации и лечении в отделениях интенсивной терапии. С учетом наиболее частого поражения дыхательной системы, большинству реанимационных пациентов требуется оксигенотерапия и длительная искусственная вентиляция легких (ИВЛ). Постинтубационный и посттрахеостомический стеноз трахеи – это ятрогенное осложнение, которое возникает у 10–22% пациентов после длительной ИВЛ среди всего пула пациентов, в то время как частота рубцовых стенозов трахеи после осложненного течения коронавирусной инфекции COVID-19 остается неизвестной. В данной работе представлены особенности диагностики и хирургического лечения.
