Sonic Poetics: Sean Bonney’s Sound Spectrum in "Our Death"
Authors: Pomery Simon
Published: August 2024

This paper presents one case study in my theory of 'sonic poetics'. Sonic poetics is the apprehension of sound and listening as each operates in the reading of a poem. However, sonic poetics is not exclusive to poetry: sonic poetics is a way of being that can be applied, through aesthetic, ethical, decolonising and antifascist contexts, to academic or non-academic practices. I centralise key acts of listening within Sean Bonney's poetry in a wide spectrum of impossible music, microsounds, inaudible sound, human and inhuman sounds. How is sound presented in his poetry and how does this inform our own listening? I give readings of what I call Bonney’s ‘sound spectrum’ in his last book, Our Death, analysing individual autonomy within dominant cultures, and trace an avant-garde tradition from Baraka, Césaire, Hölderlin, and Pasolini in poetry, to Iannis Xenakis’s ‘stochastic resonance’, and François J. Bonnet’s concept of ‘desiring-listening’, in Sound Studies. The desire of sonic poetics is for creating, listening to and within autonomous spaces. François J. Bonnet’s The Order of Sounds: a Sonorous Archipelago is a key text for sonic poetics. His voyage into archipelagic interstices of listening targets sound itself, as well as listening beyond the audible. Sonic poetics begins where Bonnet’s The Order of Sounds ends: sonic poetics examines sound and listening as it is represented in poetry.

Published: August 2024

The microstructure and impact toughness of 9 % Ni steel joints welded by shielded metal arc welding (SMAW) and gas tungsten arc welding (GTAW) were investigated. The two kinds of weld metal were mainly composed of cellular dendrites and a granular precipitated phase. The grains and cellular dendrites of the GTAW weld metal were smaller than those of the SMAW weld metal. The precipitates in the SMAW weld metal were stripe-shaped while those in the GTAW weld metal were rod-shaped; the number of precipitates in the GTAW weld metal was lower than in the SMAW weld metal. The low-temperature impact toughness of the GTAW weld metal was better than that of the SMAW weld melt.
EFFECTS OF HOT-ROLLING PROCESSES ON THE FRACTURE BEHAVIORS AND MECHANICAL PROPERTIES OF 2009Al/SiCp METAL MATRIX COMPOSITES
Authors: Wang Ze , Liang Zhiwen , Huang Qingxue , Li Zixuan , Niu Xiaomiao
Published: August 2024

Defects such as pores and weak interfacial bonding in SiC-reinforced aluminum-matrix composites (AMCs) limit the reinforcement effect. The objective of this study is to control the microstructural defects and status of the Al/SiC interface in an 2009Al/SiCp composite using rolling processes. The influence of the rolling reduction rate on the microstructure and mechanical properties is investigated. The fracture behavior of the 2009Al/SiCp composite is observed through in-situ scanning-electron-microscopy tensile tests. The results demonstrate that an appropriate rolling reduction rate can effectively eliminate microstructural defects in the matrix and enhance the interfacial bonding strength of Al/SiC. Plastic deformation during the rolling processes expands the dislocation-strengthening regions near the Al/SiC interface. Consequently, mechanical loads can be more efficiently transferred from the aluminum matrices to SiC particles. In the as-sintered specimens, cracks primarily initiate at the Al/SiC interfaces during tensile tests. In contrast, cracks predominantly propagate from the SiC particles to Al matrices in the as-rolled specimens. This work provides a fundamental understanding of the dynamic changes in the microstructure and the resulting mechanical properties during hot rolling of SiC-reinforced AMCs.

Published: August 2024

Metal oxide nanocomposites are a critical element in nanoscale technology. Because of their many uses, a great deal of study has involved photocatalytic materials. These photocatalytic degradation characteristics also included applications like solar-cell applications. Waste­water management was included in the photodegradation property. The following study explored the development of europium tungstate nanocomposites with titanium dioxide and how they can be used in photocatalytic applications. The synthesis was conducted using the hydrothermal method and is characterized by Fourier-transform infrared spectroscopy, X-ray diffraction spectroscopy, scanning electron microscopy, and energy-dispersive spectroscopy. Application experiments were conducted using four distinct dyes, namely methyl orange, methylene blue, congo red and methyl red. The photodegradation experiments were conducted using visible light emitted by a tungsten-filament lamp. Methylene blue and methyl orange degraded to 20 % and 35 % after 1 hour respectively. After 90 min, the degradation of methylene blue went down to 15 % and congo red degraded down to 9 %. With the experiment conducted, the sample showed that it had a relatively higher photodegradation property with the dyes used. The results show that the compound had better reaction with these dyes, with a degradation down to 10 %.

Published: August 2024

A calcium-based geopolymer was synthesized using a blend of recycled glass powder from solar panels (PV glass waste), limestone, and a sodium silicate solution, which underwent hydrothermal autoclaving at 180 °C for varying durations. This material is regarded as environmentally friendly and has garnered research attention worldwide. In this investigation, limestone served as the calcium source, while recycled glass from solar panels provided the SiO2 necessary for producing calcium-based geopolymer materials. Currently, solar-panel waste poses a significant environmental challenge that requires attention. The objective of this research was to develop a sustainable and high-performance calcium-based geopolymer using waste materials, specifically recycled glass from solar panels and limestone. The study aimed to evaluate the effects of hydrothermal autoclaving on the compressive strength, volume weight, porosity, and water absorption of the synthesized geopolymer, as well as to understand the microstructural transformations involved. The results revealed a remarkable 430 % increase in the compressive strength of the specimens following hydrothermal autoclaving for 24 to 96 hours compared to the unautoclaved samples. Concurrently, the volumetric weight had a substantial rise from 1.54 % to 2.31 g/cm3, with corresponding decreases in the porosity and water absorption from 38.1 % to 16.9 % and 10.26 % to 5.08 %, respectively. An X-ray diffraction (XRD) analysis of the mineral composition and a scanning electron microscope (SEM) examination of the microstructure demonstrated a transformation of all samples from an amorphous gel structure to needle- or spike-shaped fibrous, and then sheet-like CSH structures. These new structures exhibited dimensions of less than 10 µm in length, less than 2 µm in width, and less than 400 nm in thickness. The resulting CSH products constitute calcium silicate hydrate minerals, characteristic of calcium silicate materials, which are synthetic products arising from chemical reactions among SiO2, CaO, and H2O under hydrothermal conditions. This study underscores the potential of using recycled materials to produced high-strength geopolymers, offering a promising solution to the environmental challenge of solar-panel waste.

Polimer kompozitlerde matris malzemesi olarak termoplastikler daha yaygın olsa da epoksi ve polyester gibi termosetlerin kullanımı da mevcuttur. Bu çalışmanın amacı, endüstride yaygın bir şekilde kullanılan polyester reçinesi içerisine kalsit ilavesinin yanı sıra doğal bir atık malzeme olan çam talaşını ilave ederek üretilen kompozit numunelerin aşınma özelliklerini incelemektir. Kalsit (kalsiyum karbonat), inorganik dolgu maddesi olarak endüstride yoğun kullanıma sahiptir. Çam talaşı ise özellikle mobilyacılık sektöründe doğal atık olarak çıkmaktadır. Bu iki dolgu malzemesi matrise farklı oranlarda ilave edilmiştir. Elde edilen karışım açık teflon kalıba dökülerek kompozit numuneler hazırlanmıştır. Numunelerin 22 saat suda bekletilmesiyle su absorbsiyonu, pin on disk yöntemi uygulanarak aşınma özellikleri ve Shore D yöntemiyle sertlik özellikleri incelenmiştir. Kırık yüzeyler için SEM analizi yapılmıştır. Aşınma testi sonuçları talaş miktarının artmasıyla aşınmanın arttığını, kalsit miktarının artmasıyla aşınmanın azaldığını göstermiştir. Shore D sertlik testinde ise özellikle kalsit miktarının artışına bağlı olarak sertliğin arttığı görülmüştür. Su absorbsiyon testinde ise kompozit numunelerde kalsitin azalması ve talaş oranının artmasıyla su absorbsiyonunun arttığı gözlenmiştir.

Çamur dezentegrasyon yöntemleri özellikle atık çamurların anaerobik çürütülmesinden önce ön arıtım yöntemi olarak kullanılmakta ve çeşitli çamur özelliklerinde iyileşmeler sağlayabilmektedir. Bu çalışmada, konserve gıda üretimi yapan bir işletmenin atıksu arıtma tesisinden alınan atık aktif çamura hidrodinamik kavitasyon, asidik dezentegrasyon ve alkali dezentegrasyon yöntemleri uygulanmış, çözünebilir kimyasal oksijen ihtiyacı (ÇKOİ), kapiler emme süresi (KES) ve santrifüjlenebilir çökelebilirlik indeksi (SÇİ) değerlerinde meydana gelen değişimler incelenmiş ve uygulanan yöntemlerin, çamur çözünebilirliği ile susuzlaştırılabilirliği üzerindeki etkileri kıyaslanmıştır. Çalışmada çamura uygulanan tüm dezentegrasyon yöntemleri atık aktif çamurun çözünebilirliğini olumlu yönde etkilemiş ve çamurdaki ÇKOİ konsantrasyonunu önemli derecede arttırmıştır. Uygulanan yöntemler içerisinde çamurun çözünebilirliğini en fazla arttıran yöntemlerin hidrodinamik kavitasyon ve alkali dezentegrasyon (pH 11) olduğu tespit edilmiştir. Diğer yandan çamurun çözünebilirliğini en fazla arttıran bu yöntemlerin çamurun KES ve SÇİ değerlerini de arttırdığı, yani çamurun su verme performansını olumsuz yönde etkilediği sonucuna ulaşılmıştır.

The COVID-19 pandemic has demonstrated the need for novel therapeutic interventions and improved pandemic preparedness strategies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This protocol details an optimized crystallization method for the SARS-CoV-2 nsp3 macrodomain, a potential drug target. Using sitting drop vapor diffusion, we describe specific buffer conditions and procedures to consistently produce high-quality crystals suitable for XChem fragment screening. The method yields crystals that diffract to an average resolution of 1.2 Å, enabling high-resolution structural studies. All structures solved during the development of tool compounds for the SARS-CoV-2 nsp3 macrodomain are deposited on the PDB (Group deposition: G_1002283).
Considering Power and Institutional Change in the Study of Migration’s Impact on Non‐Migrants: Commentary on Schut & Crul (2024) and Keskiner et al. (2024)
Authors: Warikoo Natasha
Published: August 2024

Schut and Crul (2024) and Keskiner et al. (2024) bring much‐needed attention to migration’s impact on host societies. They investigate Dutch non‐migrant parents’ responses to migration‐related issues that arise in their children’s schooling, highlighting the diversity of those responses. Future analyses should move beyond individual analyses to understand broader social changes, how group‐level status shapes institutional responses to migration, and the role that systemic racism or Islamophobia may play in shaping individual and institutional responses to migration. This requires empirical analyses that incorporate participant observation in specific institutions (for example, schools), and attention to organizational decision‐making.

B2C AND B2B PLATFORM MODEL-BASED DETERMINANTS OF RUSSIAN INDUSTRIAL COMPANIES’ STRATEGY CHOICES FOR ENTERING FOREIGN MARKETS
Authors: Ilkevich S. V.
Published: August 2024

The article presents an overview of a number of parameters and factors influencing the choice and formation of strategies for the entry of Russian industrial enterprises into international markets based on platform models of interaction in the B2C and B2B segments. This focus makes it possible to define and specify in more detail the mechanisms, formats, opportunities and limitations in the development of strategies for the entry of Russian industrial enterprises into international markets, supported by platform models of interaction. In the context of building international platforms for industrial companies, aspects of the specifics of platform interaction have been identified. A list of twelve determinants is proposed, how to choose a strategy of entering foreign markets by Russian industrial enterprises based on the mechanisms of platform interactions. The fact is that in the current conditions of the platform economy, value creation is the result of a new combination of information, physical products and services of various types, as well as new ways of configuring transactions and reconfiguring resources, relationships between suppliers, partners and customers. For Russian industrial enterprises, methodological developments in this area can be particularly useful in the context of increasing the internationalisation of business activities using international B2C and B2B platforms. At the same time, a major difficulty in determining the parameters and priorities of platform interaction between industrial companies, especially in the B2B segment (including in the framework of industrial asset sharing models), is the fact that this type of interaction is still a frontier today in many industrial sectors at the national level, and even more so at the international level. As best practices and success stories of Russian industrial companies entering international platforms emerge, and as the platforms themselves evolve, it will be possible to talk about greater operationalisation and measurability of the determinants of Russian industrial companies’ strategy choices. At the current stage of development of international manufacturing platforms, greater awareness of the productivity drivers and determinants of industrial enterprises’ strategic choices will enable platform complementors and the platforms themselves to better find common ground and ensure faster growth of network effects.

Introduction: Weight gain and obesity are common concerns for midlife women. Obesity is characterized by an accumulation of body fat resulting in body weight at least 20% above the optimum. Objective: To evaluate the efficacy of cryolipolysis on body composition in midlife women. Methods: Thirty women aged 30-55 with overweight underwent three cryolipolysis sessions, (45 minutes each), spaced 15 days apart. Body composition was assessed using bioelectrical impedance before and after the intervention. Parameters measured included fat mass, lean mass, muscle mass, muscle/fat ratio, and total body water (TBW) percentage. Results: Significant reductions were observed in both absolute fat mass (from 26 ± 1.5 kg to 24.4 ± 1.51 kg, p<0.05) and fat mass percentage (from 34.4 ± 1.2% to 32.8 ± 1%, p<0.05). Lean mass remained stable (48.91 ± 1.56 kg to 48.82 ± 1.4 kg), with a significant increase in lean mass percentage (65 ± 1.2% to 67 ± 1.2%, p<0.05). Muscle mass percentage rise from 29 ± 0.6% to 31 ± 0.7% (p<0.05). The muscle/fat ratio improved significantly from 0.85 ± 0.04 to 0.95 ± 0.2 (p<0.05), and TBW percentage increased from 46.5 ± 0.9% to 48 ± 0.9% (p<0.01). Conclusion: Cryolipolysis significantly enhances body composition by reducing fat mass, maintaining lean mass, and improving muscle/fat ratio and hydration status. These findings underscore cryolipolysis as an effective non-invasive alternative for body contouring with potential health benefits, including improved metabolic and cardiovascular health. Future research should explore long-term effects and mechanisms to optimize clinical applications.
Problems of Legislative Regulation of a Postgraduate Student (Postgraduate in a Military College) Legal Status at a New Stage of the Russian Education System Reformation
Authors: Kulakov N. A.
Published: August 2024

The lack of its own independent concept of education amid the aggravation of the geopolitical situation and withdrawal from the Bologna process is one of the main threats to Russia’s national security. The author attempts to objectively assess the current state of legal regulation in the field of higher education. The paper characterizes the changes in the parameters of standardization in education in the context of domestic reforms due to the entry into the Bologna process. The author argues that legislative innovations at this historical stage determined a number of systemic problems of public administration in the field of education, one of which is related to the place of training highly qualified academic personnel. The conducted research allowed us to formulate a number of proposals for improving legislation. Firstly, the training of scientific and academic personnel should be allocated to an independent level of postgraduate education. Secondly, defining the specifics of postgraduate education, it is necessary to consolidate that the legal status of students in higher education training programs is determined, along with the legislation on education, also by the legislation on scientific activity. A postgraduate student should be equated with a researcher in the sense of Article 4 of Federal Law No. 127-FZ dated 23.08.1996 «On Science and State Scientific and Technical Policy».
International Legal Regulation of Biodiversity Conservation in Northern Latitudes (Part 1)
Authors: Teymurov E. S.
Published: August 2024

Environmental problems are one of the strongest drivers of the development of international law, in some cases, they do act as a way to restrict certain types of activities for certain states. They are of particular importance in the context of polar regions resources usage. The study aims to identify problems and formulate proposals for the development of Russia’s legal position on the conservation of biodiversity in the northern latitudes, as well as to assess the applicability of the universal regime of biodiversity management and the experience of conservation of Antarctic biodiversity. Key threats to the conservation of biodiversity in the northern latitudes include climate change, fishing, marine pollution, tourism and insufficient scientific data on the ecosystems of the region. Fishing poses an immediate threat to the biodiversity of the Arctic, while other threats are the consequences of various human activities. Territorial claims in the Arctic have virtually no effect on the conservation and management of the region’s biodiversity. There is no special treaty on combating climate change and its consequences in the Arctic, because the problem is caused by activities under the jurisdiction of states, has a global character and does not depend solely on the efforts of the Arctic states. Regarding the prevention of pollution of the Arctic marine environment, states recognize the applicability of universal international treaties and decisions of the International Maritime Organization. Legal regulation of tourism in the Arctic is carried out at the national level, with the mandatory implementation of universal environmental obligations, including environmental impact assessment, waste disposal, and the use of zonally linked management tools.

Developing professional competence among future teachers is a key aspect of the modern education system, especially in the context of the rapid advancement of digital technologies. Since the early 1990s, the European Union has paid special attention to the education and training of highly qualified educators capable of effectively utilizing modern teaching methods. The report “Europe and the Global Information Society” emphasized the need for integrating new technologies into the educational process. This research project focuses on a relatively unexplored area—the use of digital technologies to develop future chemistry teachers’ competencies in Kazakhstan. The research aims to enhance understanding of the effective application of digital technologies in chemistry education and provide practical recommendations to improve the quality of education. The study utilized various methods, including theoretical analysis, online surveys, modeling, experiments, and the analysis of test results. Survey results among students confirmed the importance of using digital technologies to develop the professional competence of future chemistry teachers. A pedagogical experiment using digital technologies revealed the effectiveness of educational and methodological support specifically designed to enhance the professional skills of future chemistry teachers. Monitoring results indicated a significant increase in the professional competence of experiment participants. These findings are crucial for the developing curriculum aimed at preparing future chemistry teachers and contribute to the improvement of education quality in this field. The conclusions drawn can be used to further enhance teaching methods in chemistry using digital technologies in Kazakhstan and other countries.
Evaluating the Effects of Long-term Exposure to Fine Particu-late Matter (PM2.5) on Depressive Mood among Korean Older Adults Using Multilevel Analysis
Authors: Jo Kyunghee
Published: August 2024

Background: The harmful effects of particulate matter (PM) are amplified in older adults, who experience a decline in physiological function, reducing their ability to expel and detoxify inhaled PM. Moreover, older adults may be more vulnerable to fine particulate toxicity due to underlying medical conditions. We assessed the effects of long-term exposure to fine particulate matter (PM2.5) on depressive mood (DM) in adults aged > 65 yr using community-based data.
Methods: In the 2017, Korean Community Health Survey (KCHS) data, data of PM2.5 and community factors were constructed based on participants who responded to DM in a sample of 67,802 individuals. To evaluate the effect of PM2.5 on DM among older adults, a multilevel regression model was constructed using individual-(KCHS) and community-level data (PM2.5, green area per capita, urban area, social welfare budget, health, and social business). For PM2.5, an independent variable, quartiles were used to classify regions according to concentration.
Results: A positive correlation was found between PM2.5 and DM of older adults. Compared to Q1, the odds ratio increased to 1.15 (95% CI 0.76-1.74) in Q2, 1.55 (95% CI 1.02-2.35) in Q3, and 1.60 (95% CI 1.16-2.20) in Q4.
Conclusion: DM may increase in older individuals living in areas with high PM2.5. Systematic mental health management is required for older individuals residing in such areas.

Published: August 2024

Background: Carpal tunnel syndrome (CTS) is a common disease resulting from the median nerve entrapment at the wrist. Although CTS (prevalence=5%–10% in the general population) is the most common neuropathy, its molecular mechanisms need elucidation. We used bioinformatics to detect genes with differential expressions in CTS and introduce the molecular regulatory noncoding RNAs and signaling pathways involved.
Methods: The raw files of the RNA sequencing of CTS patients and controls were obtained from GEO (accession: GSE108023), and the samples were analyzed. Differentially expressed genes were isolated using DESeq2 R. Functional analyses were conducted on the signaling pathways, biological processes, molecular functions, and cellular components of the differentially expressed genes. Additionally, interactions between the most differentially expressed genes and miRNAs and lncRNAs were investigated bioinformatically.
Results: Upregulation and downregulation were observed in 790 and 922 genes, respectively. The signaling pathway analysis identified the metabolism pathways of arachidonic acid, linoleic acid, and tyrosine as the most significant pathways in CTS. Moreover, PLA2G2D and PLA2G2A with upregulated expressions and PLA2G2F, PLA2G4F, PLA2G4D, PLA2G3, and PLA2G4E with downregulated expressions were genes from the phospholipase family playing significant roles in the pathways. Further analyses demonstrated that hsa-miR-3150b-3p targeted PLA2G2A and PLA2G4F, and RP11-573D15.8-018 lncRNA had regulatory interactions with the aforementioned genes.
Conclusion: Molecular studies on CTS will clarify the involved signaling pathways and provide critical data for biomedical research, drug development, and clinical applications.

Optimal methods of synthesis of germanium(IV) complexes with gluconic acid (H6Gluc) and exo-ligands niacin (Nic), niamide (Nad) and isoniazid (Ind) in aqueous solution were developed. The structure and stereochemistry of the presented complexes were stated by elemental analyses, thermal analysis, IR spectroscopy and single crystal X-ray analysis. It was shown the formation of supramolecular salts of the composition (NicH)2[Ge2(OH)2(μ-H2Gluc)2]·3H2O (1), (NadH)2[Ge2(OH)2(μ-H2Gluc)2]·3H2O (2), (IndH)2[Ge2(OH)2 (μ-H2Gluc)2] (3).
It was established that complex 2 consists of two protonated niamide molecules and a complex anion in which two germanium atoms are coordinated by two bridging ligands of deprotonated gluconic acid H2Gluc4-. The trigonal-bipyramidal polyhedron of Ge(IV) is additionally formed by the coordination of the hydroxyl group. In the crystalline phase, the complex exists as a trihydrate.
