Authors: Özdemir Rana Can , Işık Meryem Türkan , Durukan Hüseyin 
Published: November 2024

AbstractObjectiveIt is extremely important for healthcare professionals to protect patients' privacy during diagnosis and treatment processes related to gynecology and obstetrics and to warn them in case patients' privacy is violated. This study was aimed at determining attitudes of female patients having obstetrics examination towards privacy and raising their awareness of privacy.MethodsThis cross‐sectional‐descriptive study was conducted with 410 patients who presented to the gynecology and obstetrics outpatient clinic of a university hospital. The survey form consisted of two forms: The descriptive characteristics questionnaire and the body privacy scale for gynecology and obstetrics (BPSGO). Frequency tables, descriptive statistics, Mann–Whitney U‐test, Kruskal–Wallis H‐test, and Bonferroni correction were used in the analysis of the data.ResultsThe mean age of the participants was 36.75 ± 11.18 years. Of these, 38.0% were in the age group of ≥40 years, 84.0% were married, 66.8% presented to the gynecology clinic, and 58.3% had negative emotions before they had gynecologic examination. Ethics and privacy subscale scores of the single participants were significantly higher than were those of the married participants.ConclusionIt was determined that privacy was affected by cultural characteristics, belief systems and personal values, and that most of the participants were likely to experience negative emotions. It is important to raise health professionals' awareness of privacy by drawing their attention to the value of privacy which is among ethical values in their education and to support the better functioning of legal regulations on this issue.

AbstractTreatment of halide substituted bidentate [C,N] and tridentate [C,N,S] Schiff base ligands with palladium(II) acetate or with lithium tetrachloropalladate, as appropriate, afforded through C−H activation of the organic ligand, the dinuclear (1 a, 1 b) and mononuclear (1 c, 1 d, 1 e) palladacycles, respectively. Reaction of the μ‐acetate dinuclear complexes with aqueous sodium chloride in a metathesis process, gave the μ‐chloride dinuclear complexes (2 a, 2 b). Treatment of the latter with triphenylphosphine or with bis(diphenylphosphino)methane (dppm)/ammonium hexafluorophosphate in complex/ phosphine 1 : 2 ratio, gave the phosphine derivatives (3 a, 3 b, 4 a, 4 b). Reaction of 1 c and of 1 e with triphenylphosphine/silver perchlorate and dppm/silver perchlorate, respectively, gave compounds 2 c and 2 e with removal of the chloride ligand by precipitation of the silver halide. The compounds were characterized by microanalysis (CHN), IR and 1H and 31P{1H} NMR spectroscopy. The crystal structures of three complexes, 4 a, 1 c and 1 e were studied by single‐crystal X‐ray diffraction. Furthermore, the performance of the palladacycles were tested as pre‐catalysts, namely Suzuki‐Miyaura cross‐coupling reaction and those furnishing the better results are also reported.

AbstractThe study aimed to evaluate the physicomechanical properties and polymerization shrinkage of the newly developed flowable composite (FC). The physical and mechanical properties assessed include flowability, radiopacity, depth of cure, surface roughness, compressive strength, and compressive modulus. The newly developed FC was prepared by incorporating zirconia as a radiopacifying agent and nanohybrid silica derived from rice husk as fillers, with the monomer ratio of urethane dimethacrylate to triethylene glycol dimethacrylate (UDMA:TEGDMA) manipulated at 20:80, 30:70, 50:50, 60:40, 80:20, and 90:10. Filtek Supreme Ultra Flowable Restorative, Revolution Formula 2 and G‐aenial Universal Flo served as control groups. The data were statistically analyzed using one‐way ANOVA and post‐hoc Tukey tests. The newly developed FCs, with flowability levels classified as high, medium, and low‐flow, were found to be radiopaque. As the UDMA ratio in the newly developed FCs increased, depth of cure, compressive strength, and compressive modulus increased, while surface roughness and polymerization shrinkage decreased. Comparable values were observed between the newly developed FCs and control groups in flowability, surface roughness, compressive modulus, and polymerization shrinkage. In summary, the newly developed radiopaque FCs could serve as sustainable dental restorative materials by enhancing diagnostic accuracy, improving physicomechanical properties, and minimizing polymerization shrinkage.Highlights
Different UDMA:TEGDMA ratios were crucial in determining the properties
The three different levels of flowability were confirmed to be radiopaque
Higher ratio of UDMA improved the physical and mechanical properties
Higher ratio of UDMA reduced the polymerization shrinkage

AbstractThe electromagnetic properties of epoxy‐based composites filled with carbon‐coated copper (Cu@C) nanoparticles and multi‐walled carbon nanotubes (MWCNTs), along with hybrid MWCNT/Cu@C/Epoxy systems containing varying concentrations of nanoinclusions, were systematically investigated across multiple frequency and temperature ranges. Measurements were conducted in the low‐frequency range (20 Hz–1 MHz) and over a temperature span of 40–500 K, as well as in the microwave frequency range (26–37 GHz) at room temperature. The percolation threshold was identified at approximately 2.5 vol% for composites containing only Cu@C nanoparticles and at 0.3 vol% for composites with MWCNTs. Notably, the hybrid MWCNT/Cu@C/Epoxy composites exhibited significantly enhanced electromagnetic properties compared to those of the single‐filled systems. At room temperature, an epoxy composite containing 5 vol% Cu@C and 1 vol% MWCNT exhibits a conductivity of approximately 4 × 10−2 S/m, which increases by nearly two orders of magnitude following a thermal cycle up to 500 K. The total electromagnetic interference (EMI) shielding effectiveness in the 26–37 GHz range was measured between 4 and 9 dB, indicating the material's promising potential for attenuating microwave noise. Dynamic mechanical analysis (DMA) results revealed that increasing the MWCNT content improved the storage modulus of the composites but led to a reduction in the glass transition temperature (Tg), which was observed to range between 40 and 50°C. The incorporation of MWCNTs and Cu@C nanoparticles into epoxy matrices offers a promising approach for the development of lightweight multifunctional composites with superior electrical, mechanical, and EMI shielding properties.Highlights
The percolation threshold in MWCNT/Epoxy composites is 0.3%.
The percolation threshold in Cu@C/Epoxy composites is 2%.
The conductivity value of MWCNT/Cu@C/Epoxy composites is around 4 × 10−2 S/m.
The total shielding effectiveness in the Ka‐band range between 4 and 9 dB.
Glass transition temperature of MWCNT/Cu@C/Epoxy is between 40 and 50°C.
Enhancing the properties and performance of ground nut shell biocomposites using compatibilizers and flame retardants

Published: November 2024

AbstractComposites developed from inexpensive, renewable, sustainable, and abundant bioresources such as groundnut shells (GNS) do not have the adequate properties required for commercial applications. Hence, most of the biocomposites developed from agricultural wastes or biomass are not used for practical applications. In this study, we have demonstrated that the addition of compatibilizers and flame‐resistant chemicals considerably enhances and makes the properties of GNS‐reinforced polypropylene (PP) composites suitable for commercial applications. One maleated polypropylene (MAPP) and two acrylic‐based compatibilizers (ABC1 and ABC2) were chosen and added into the composites in different proportions (1% to 5%). Ammonium polyphosphate (APP) was used to increase the flame retardancy of the composites. Ratio of reinforcement and matrix and composite forming conditions were also changed to achieve maximum benefits, and composites containing up to 80% GNS were developed. Tensile strength showed a good increase of 48%, whereas modulus showed a decrease of 35% with the addition of ABC2. However, the flexural strength and modulus of the composites increased with the addition of even 1% MAPP. The mechanical properties of the composites decreased when excess (5%) compatibilizer was used, probably due to agglomeration or an increase in incompatibility. Adding 3% of APP significantly improves both the flammability rating, LOI, and thermal properties. The highest flame resistance rating of V0 was obtained for both ratios, with the LOI increasing by about 40% and the conductivity decreasing marginally from 0.982 to 0.808 W/mK. Further, reduction in water absorption and hence increase in durability were also possible.Highlights
GNS are major byproducts with limited use.
Composites made from GNS have poor mechanical and performance properties.
Addition of compatibilizers leads to substantial improvement in properties.
Excellent thermal and flame resistance is imparted by APP.
GNS composites are suitable for building, automotive, and other applications.

AbstractThere is diverse literature on the Arab Mashreq, varying from analysis to readings of interdisciplinary political, social, and economic sciences (World Bank, Economic integration in the Mashreq. World Bank, Middle East and North Africa Region, 2010). In order to analyze the contextual reality and challenges of marriage in the Arab Mashreq, and despite the common infrastructure and societies of these countries, it is expected that each country is characterized by distinguishing fundamental differences, historically, socially, politically, economically, and culturally. In fact, many differences emerge between regions and provinces within the same country.
Influence of Diaphragms on Pressure and Heat Flux Measurements in a Shock Tunnel

Published: November 2024

AbstractAn experimental study investigated the flow disturbances caused by diaphragm debris in a shock tunnel, specifically between a driven tube and a nozzle. The impact of debris-induced disturbances on pressure and heat flux measurements was examined with two types of diaphragms: a single-layer ultra-thin polyethylene film and a double-layer diaphragm, where eight direction pre-cut polyethylene film was sealed with copper tape. The study involved measuring the pitot pressure and stagnation-point heat flux, using a flat-faced model and a hemisphere model, respectively. The pitot pressure was measured using a piezoelectric-based pressure transducer, while heat flux was recorded with a fast-response surface-junction coaxial thermocouple calibrated through the water-plunging method. The experimental data for both diaphragms correlated well with theoretical predictions. The shadowgraph flow visualization technique was employed to visualize diaphragm debris. The flow quality in the shock tunnel was assessed by analyzing normalized disturbances, representing fluctuations in pitot pressure, and heat flux measurements. The experimental results indicated that the double-layer diaphragm effectively reduced diaphragm debris and improved flow quality in shock tunnel experiments.
Genesis of artesian waters

Published: November 2024

AbstractMankind has entered the era of fresh water scarcity. And the questions of the origin of these waters, as well as the methods of effective search for underground fresh water, become fundamental for the assessment of the prospects of water supply of the Earth's population not only in theoretical, but also in applied values. The article considers the volcanic-marine paradigm of artesian water genesis, which allows a logical explanation of a number of deep freshwater phenomena that cannot be resolved by other theories. The main consequences of the volcanic-marine paradigm are: (a) artesian water is recoverable, (b) deep freshwater resources are included in the water cycle in nature like groundwater, (c) the problem of extracting potable artesian water is not a resource problem for mankind, but a technological problem. At present, artesian water is searched for by drilling wells (direct method) and by geophysical methods of groundwater exploration—electrical survey, seismic survey and magnetic resonance method. At the same time, the great depth of artesian water, up to 1000 m, makes it difficult to locate it using geophysical methods. The article considers the geophysical method of direct detection of artesian water in various geological structures at great depths. This method and the service based on it have been named “Geodirect RSS/NMR”. Their physical basis is the resonance between the pre-recorded spectrum of the sought substance (in our case, artesian water) and the spectrum of radiations recorded by the satellite instrumentation in the infrared range. The presence of resonance allows direct identification of artesian water flows and reservoirs without interpretation of indirect data.
Textile and food waste biodegradation for the production of composite mycelium materials using Pleurotus ostreatus

Published: November 2024

Abstract
The fashion industry produces over 100 billion garments per year, of which 85% end up in landfill before the end of the year. Considering filamentous fungi are capable of biodegrading cellulose and complex molecules and of producing a wide range of biomaterials, an opportunity to rethink the linearity of the textile industry emerges. Biodegradation of various combinations of denim textile waste, synthetic textile waste, food waste and spent coffee grounds were investigated using Pleurotus ostreatus mycelium. The resulting composite material was tested for its use in material production. The outcomes of the study showed that Pleurotus ostreatus mycelium could successfully grow on all the combinations of food waste (vegetable peels and coffee grounds) with textile waste (synthetic textile and denim textile), and even on denim textile waste only. Provided the soft nature of the substrate, the textile and food waste mycelium composite is also malleable, and therefore interesting for applications in the textile industry. A protocol for post processing of the flexible composite material using low energy and natural components (heat, water, glycerol, and wax) was created to transform the composite into a leather-like fungal material.
Cascading employment as paradigmatic form of precarious work: The case of IT agency workers in the United States
Authors: Liang Xiaochen 
Published: November 2024

Abstract
Cascading employment is an increasingly prevalent yet understudied form of employment arrangement, where an employer places a worker in a client’s workplace through a sequence of labour intermediaries, with no direct contractual relationship between the worker’s employer and the end client. In this article, cascading employment is conceptualised as a distinct and normalised form of precarious work and differs from ‘triangular employment’ in several dimensions. The study reported herein draws on interviews with U.S.-based IT workers and stakeholders engaged in cascading employment. Findings reveal three key dimensions of cascading employment: multilayeredness, hierarchical fissuring, and relationship heterogeneity. These dimensions contribute to the aspects of precariousness of employment, including diluted income, heightened employment uncertainty, reduced worker control over working conditions, and limited legal protections. Moreover, the precariousness of cascading employment stems from the complexity of the employment arrangements, not merely from factors such as contract type, employment status, and industry, which are typical in explaining precariousness. Therefore, ‘complexity of employment arrangements’ should be recognised as a crucial criterion for employment precariousness. ‘Complexity’ can be measured by the number of actors involved, the extent of fissuring in employer costs and responsibilities, and the variety and intensity of inter-actor relationships.

Published: November 2024

Abstract
The latest Yakult Science Study Day was held virtually on 2 November 2023. Aimed at healthcare professionals, researchers, and students, a variety of experts explored the latest gut microbiome research and what it means in practice. The morning sessions discussed the role of the microbiome in health and disease, the rapid advancements in DNA sequencing and implications for personalised nutrition, the current state of evidence on health benefits associated with fermented foods, prebiotics and probiotics and the challenges involved in interpreting research in this area. The afternoon session considered the emerging research on the microbiota–gut–brain axis in mediating effects of food on mood, the bidirectional impact of menopause on the gut microbiota, and the interplay between the gut and skin with implications for the treatment of rare and common skin disorders. The session ended with an update on the use of faecal microbiota transplant in both research and clinical practice. Undoubtedly, the gut microbiome is emerging as a key conductor of human health, both in relation to gastrointestinal and non-gastrointestinal outcomes. As research continues to elucidate mechanisms of action and confirm their effects in human trials, the gut microbiome should be a key consideration within a holistic approach to health moving forward.
Campana, the ‘End of Art’, and Hegel’s Philosophy of Literature
Authors: Liu Chunge 
Published: November 2024

Abstract
Based on Hegel’s thesis of the ‘end of art’, this paper aims to explore how to study Hegel’s philosophy of literature by carrying out a dialogue with Francesco Campana. In his recent book, The End of Literature, Hegel, and the Contemporary Novel (2019), Campana demonstrates how literature resists its end by continuous self-transformation and provides a framework of ‘philosophization’–‘poetry’–‘ordinariness’ in understanding the contemporary novel. While, to some extent, I agree with him on the understanding of the ‘end of art’ thesis, I object to his idea that ‘philosophization’ and ‘ordinariness’ are two poles between which poetry moves. I defend the view that, from the perspective of Hegel’s absolute and taking Hegel’s philosophy as a totality, ‘philosophization’ and ‘ordinariness’ are inseparable. Furthermore, I emphasize the significance of Hegel’s thesis of the ‘end of art’, which I argue lies in revealing the problem of modern subjectivity. Literature, as a unique form of art, also reveals this problem and helps to solve it. Therefore, in the study of Hegel’s philosophy of literature, I insist on adopting the perspective of Hegel’s absolute and taking Hegel’s philosophy as a whole so that we can build connections among different disciplines and among different art-forms and art-types. With this perspective, I make some proposals, which include several paradigms for the study of Hegel’s philosophy of literature. Finally, in terms of the thesis of the ‘end of art’, I maintain that the study of Hegel’s philosophy of literature is to address the problem of modern subjectivity.

Abstract
The emergence of vascular plants, such as Cooksonia, had a profound impact on Earth’s Early Paleozoic biogeochemical cycles (e.g. atmospheric oxygen, nitrogen and CO2), potentially triggering global environmental and biological changes. However, the timing of Cooksonia’s terrestrial emergence remains elusive as phylogenetic models, microfossils and macrofossils provide different timings for land colonization by vascular plants. Here, hundreds of zircon grains from three siltstones were dated using Laser Ablation-Inductively Couple Plasma-Mass Spectrometry (LA-ICP-MS). The study presents detrital zircon U-Pb dates, which refine the current biostratigraphy ages assigned to Cooksonia macrofossils from the three oldest sites globally. Specifically, siltstones hosting Cooksonia macrofossils from Borrisnoe Mountain (Ireland) and Capel Horeb (Wales) yield Gorstian–Homerian maximum depositional ages (MDAs) of 426 ± 2 Ma and 427 ± 2 Ma, respectively. Additionally, Cwm Graig Ddu (Wales) yields a (Pridoli-Ludlow) maximum age of 423 ± 3 Ma. The findings provide the first detrital zircon U-Pb dates for the oldest Cooksonia macrofossils globally and contribute crucial maximum ages. These maximum ages are instrumental in refining future calibrations of molecular clocks and improving phylogenetic models, thus contributing significantly to a better understanding of Cooksonia’s evolutionary history, including its environmental and ecological impacts.

Abstract
Developing effective, sustainable strategies that promote social inclusion, reduce isolation, and support older adults’ wellbeing continues to be important to aging communities in Canada. One strategy that targets community-living older adults involves identifying naturally occurring retirement communities (NORCs) and supporting them through supportive service programs (NORC-SSPs). This qualitative descriptive study utilized semi-structured interviews to explore how older adults living in a NORC supported by an SSP, sought to build, and maintain, a sense of community during the COVID-19 pandemic. Analysis revealed how changes in context prompted changes in the program and community, and how despite lack of in-person opportunities participants continued to be together and do occupations together in creative ways that supported their sense of community. NORC-SSPs, like Oasis, play an important role in supporting older adults’ capacity to build strong, resilient communities that support wellbeing, during a global pandemic and in non-pandemic times.
