The Impact of Water Injection and Hydrogen Fuel on Performance and Emissions in a Hydrogen/Diesel Dual-Fuel Engine
Authors: Sharkey Ashley , Zare Ali
Published: November 2024

As the need for alternative energy sources and reduced emissions grows, proven technologies are often sidelined in favour of emerging solutions that lack the infrastructure for mass adoption. This study explores a transitional approach by modifying existing compression ignition engines to run on a hydrogen/diesel mixture for performance improvement, utilising water injection to mitigate the drawbacks associated with hydrogen combustion. This approach can yield favourable results with current technology. In this modelling study, ten hydrogen energy ratios (0–90%) and nine water injection rates (0–700 mg/cycle) were tested in a turbocharged Cummins ISBe 220 31 six-cylinder diesel engine. An engine experiment was conducted to validate the model. Key performance indicators such as power, mechanical efficiency, thermal efficiency, indicated mean effective pressure (IMEP), and brake-specific fuel consumption (BSFC) were measured. Both water injection and hydrogen injection led to slight improvements in all performance metrics, except BSFC, due to hydrogen’s lower energy density. In terms of emissions, CO and CO2 levels significantly decreased as hydrogen content increased, with reductions of 94% and 96%, respectively, at 90% hydrogen compared to the baseline diesel. Water injection at peak rates further reduced CO emissions by approximately 40%, though it had minimal effect on CO2. As expected, NOx (which is a typical challenge with hydrogen combustion and also with diesel engines in general) increased with hydrogen fuelling, resulting in an approximately 70% increase in total NOx emissions over the range of 0–90% hydrogen energy. Similar increases were observed in NO and NO2, e.g., 90% and 57% increases with 90% hydrogen, respectively. However, water injection reduced NO and NO2 levels by up to 16% and 83%, respectively, resulting in a net decrease in NOX emissions in many combined cases, not only with hydrogen injection but also when compared to baseline diesel.

Published: November 2024

The flame retardant bisphenol AP bis(diphenyl phosphate) (BAPDP) is synthesized from triphenyl phosphate and bisphenol AP via transesterification, producing a polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) with a high flame retardancy and thermal stability. In this study, flame-retardant PC/ABS blends with various BAPDP contents are prepared, and their flame retardancy is studied using the limit oxygen index, vertical combustion, thermogravimetric analysis, and cone calorimeter testing. With a BAPDP content of 20 wt%, the product exhibits a limiting oxygen index of 25.4% and achieves the UL-94 V-0 grade, with a thermal deformation temperature of 72.6 °C. BAPDP improves the flame retardancy of the PC/ABS blends and exhibits fewer adverse effects on the thermal deformation temperature than other commercial flame retardants at the same concentration.

Published: November 2024

Sambucus sibirica, a deciduous shrub from the Adoxaceae family, is a traditional Kazakh medicine used in Xinjiang, China. Its branches, leaves, and fruits are used to treat fractures, rheumatoid arthritis, and nephritis. To advance research on S. sibirica, we conducted studies on its microscopic identification, chemical composition, and biological activity. The cross-sectional features of the branches, leaves, and fruits were observed under a microscope, revealing different types of ducts, cork cells, non-glandular hairs, oil droplets, stone cells, scale hairs, and star-shaped hairs in the S. sibirica powders. Fourier transform infrared spectroscopy (FTIR) was used to characterize the presence of specific chemical groups, revealing similarities and differences between different parts. Thin-layer chromatography (TLC) confirmed that chlorogenic acid was present in the branches, leaves, and fruits, whereas rutin was more prominent in the leaves. The total flavonoid contents were determined by a photocolorimetric approach and resulted in values of 7419.80, 5193.10, and 3629.10 μg·g−1 (dry weight) for the leaves, branches, and fruits, respectively. Further qualitative and quantitative analyses via ultra-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry (UPLC-QqQ-MS/MS) identified rutin, chlorogenic acid, quercetin, isoquercetin, and astragalin, with contents ranging from 1.00 to 4535.60 μg·g−1 (dry weight). Antioxidant tests revealed that the branches, leaves, and fruits of S. sibirica presented antioxidant properties, with the leaves demonstrating the highest activity, followed by the branches and fruits. These results align with the results of the quantitative analysis. This study provides valuable insights into the microscopic features, chemical composition, and antioxidant activity of S. sibirica, laying the foundation for its pharmacognosy research and quality standards and offering a reference for its future development and utilization.

Published: November 2024

This study explored the preparation of pure silica KIT-6, as well as KIT-6 materials with an enhanced concentration of surface OH groups through aluminum incorporation or NH4F treatment. These materials with various contents of surface OH groups were subsequently modified via the post-synthesis grafting of sulfonic groups using 3-mercaptopropyltrimethoxysilane as a precursor, followed by oxidation to introduce acidic sites. The catalysts were thoroughly characterized using XRD, nitrogen adsorption/desorption, SEM-EDS, TEM, and FT-IR techniques to confirm their structural and chemical properties. The catalytic activity of acid-functionalized mesoporous silicas of the KIT-6 structure was further evaluated in the acetalization of glycerol to produce solketal. The results demonstrated a significant influence of the surface OH group concentration and acidic site density on catalytic performance, with KIT-6_F_SO3H showing the highest efficiency in glycerol-to-solketal conversion. This study provides valuable insights into the design of efficient catalytic systems for the valorization of biodiesel-derived glycerol into high-value chemicals, offering a sustainable approach to waste glycerol utilization.

BG-YOLO: A Bidirectional-Guided Method for Underwater Object Detection
Authors: Cao Ruicheng , Zhang Ruiteng , Yan Xinyue , Zhang Jian
Published: November 2024

Degraded underwater images decrease the accuracy of underwater object detection. Existing research uses image enhancement methods to improve the visual quality of images, which may not be beneficial in underwater image detection and lead to serious degradation in detector performance. To alleviate this problem, we proposed a bidirectional guided method for underwater object detection, referred to as BG-YOLO. In the proposed method, a network is organized by constructing an image enhancement branch and an object detection branch in a parallel manner. The image enhancement branch consists of a cascade of an image enhancement subnet and object detection subnet. The object detection branch only consists of a detection subnet. A feature-guided module connects the shallow convolution layers of the two branches. When training the image enhancement branch, the object detection subnet in the enhancement branch guides the image enhancement subnet to be optimized towards the direction that is most conducive to the detection task. The shallow feature map of the trained image enhancement branch is output to the feature-guided module, constraining the optimization of the object detection branch through consistency loss and prompting the object detection branch to learn more detailed information about the objects. This enhances the detection performance. During the detection tasks, only the object detection branch is reserved so that no additional computational cost is introduced. Extensive experiments demonstrate that the proposed method significantly improves the detection performance of the YOLOv5s object detection network (the mAP is increased by up to 2.9%) and maintains the same inference speed as YOLOv5s (132 fps).

Published: November 2024

Venous blood collection is a widely used medical diagnostic technique, and with rapid advancements in robotics, robotic venous blood collection has the potential to replace traditional manual methods. The success of this robotic approach is heavily dependent on the quality of vein imaging. In this paper, we develop a vein imaging device based on the simulation analysis of vein imaging parameters and propose a U-Net+ResNet18 neural network for vein image segmentation. The U-Net+ResNet18 neural network integrates the residual blocks from ResNet18 into the encoder of the U-Net to form a new neural network. ResNet18 is pre-trained using the Bootstrap Your Own Latent (BYOL) framework, and its encoder parameters are transferred to the U-Net+ResNet18 neural network, enhancing the segmentation performance of vein images with limited labelled data. Furthermore, we optimize the AD-Census stereo matching algorithm by developing a variable-weight version, which improves its adaptability to image variations across different regions. Results show that, compared to U-Net, the BYOL+U-Net+ResNet18 method achieves an 8.31% reduction in Binary Cross-Entropy (BCE), a 5.50% reduction in Hausdorff Distance (HD), a 15.95% increase in Intersection over Union (IoU), and a 9.20% increase in the Dice coefficient (Dice), indicating improved image segmentation quality. The average error of the optimized AD-Census stereo matching algorithm is reduced by 25.69%, and the improvement of the image stereo matching performance is more obvious. Future research will explore the application of the vein imaging system in robotic venous blood collection to facilitate real-time puncture guidance.

Authors: Su Qin , Yao Yuan , Chen Cheng , Chen Bo
Published: November 2024

Land surface temperature (LST) is a critical parameter for understanding climate change and maintaining hydrological balance across local and global scales. However, existing satellite LST products face trade-offs between spatial and temporal resolutions, making it challenging to provide all-weather LST with high spatiotemporal resolution. In this study, focusing on Chengdu city, a framework combining a spatiotemporal fusion model and machine learning algorithm was proposed and applied to retrieve hourly high spatial resolution LST data from Chinese geostationary weather satellite data and multi-scale polar-orbiting satellite observations. The predicted 30 m hourly LST values were evaluated against in situ LST measurements and Sentinel-3 SLSTR data on 11 August 2019 and 21 April 2022, respectively. The results demonstrate that validation based on the in situ LST, the root mean squared error (RMSE) of the predicted LST using the proposed framework are around 0.89 °C to 1.23 °C. The predicted LST is highly consistent with the Sentinel-3 SLSTR data, and the RMSE varies from 0.95 °C to 1.25 °C. In addition, the proposed framework was applied to Xi’an City, and the final validation results indicate that the method is accurate to within about 1.33 °C. The generated 30 m hourly LST can provide important data with fine spatial resolution for urban thermal environment monitoring.
Validity of Linear and Nonlinear Measures of Gait Variability to Characterize Aging Gait with a Single Lower Back Accelerometer
Authors: Piergiovanni Sophia , Terrier Philippe
Published: November 2024

The attractor complexity index (ACI) is a recently developed gait analysis tool based on nonlinear dynamics. This study assesses ACI’s sensitivity to attentional demands in gait control and its potential for characterizing age-related changes in gait patterns. Furthermore, we compare ACI with classical gait metrics to determine its efficacy relative to established methods. A 4 × 200 m indoor walking test with a triaxial accelerometer attached to the lower back was used to compare gait patterns of younger (N = 42) and older adults (N = 60) during normal and metronome walking. The other linear and non-linear gait metrics were movement intensity, gait regularity, local dynamic stability (maximal Lyapunov exponents), and scaling exponent (detrended fluctuation analysis). In contrast to other gait metrics, ACI demonstrated a specific sensitivity to metronome walking, with both young and old participants exhibiting altered stride interval correlations. Furthermore, there was a significant difference between the young and old groups (standardized effect size: −0.77). Additionally, older participants exhibited slower walking speeds, a reduced movement intensity, and a lower gait regularity. The ACI is likely a sensitive marker for attentional load and can effectively discriminate age-related changes in gait patterns. Its ease of measurement makes it a promising tool for gait analysis in unsupervised (free-living) conditions.

Published: November 2024

During the production process of inkjet printing labels, printing defects can occur, affecting the readability of product information. The distinctive shapes and subtlety of printing defects present a significant challenge for achieving high accuracy and rapid detection in existing deep learning-based defect detection systems. To overcome this problem, we propose an improved model based on the structure of the YOLOv5 network to enhance the detection performance of printing defects. The main improvements include the following: First, we introduce the C3-DCN module to replace the C3 module in the backbone network, enhancing the model’s ability to detect narrow and elongated defects. Secondly, we incorporate the Large Selective Kernel (LSK) and RepConv modules into the feature fusion network, while also integrating a loss function that combines Normalized Gaussian Wasserstein Distance (NWD) with Efficient IoU (EIoU) to enhance the model’s focus on small targets. Finally, we apply model pruning techniques to reduce the model’s size and parameter count, thereby achieving faster detection. Experimental results demonstrate that the improved YOLOv5 achieved a mAP@0.5 of 0.741 after training, with 323.2 FPS, which is 2.7 and 20.8% higher than that of YOLOv5, respectively. The method meets the requirements of high precision and high efficiency for printing defect detection.

Published: November 2024

This study aims to investigate the association between the natural level of blood biomarkers and electroencephalographic (EEG) markers. Resting EEG theta, alpha (ABP), beta, and gamma frequency band powers were selected as linear EEG markers indicating the level of EEG power, and Higuchi’s fractal dimension (HFD) as a nonlinear EEG complexity marker reflecting brain temporal dynamics. The impact of seven different blood biomarkers, i.e., glucose, protein, lipoprotein, HDL, LDL, C-reactive protein, and cystatin C, was investigated. The study was performed on a group of 52 healthy participants. The results of the current study show that one linear EEG marker, ABP, is correlated with protein. The nonlinear EEG marker (HFD) is correlated with protein, lipoprotein, C-reactive protein, and cystatin C. A positive correlation with linear EEG power markers and a negative correlation with the nonlinear complexity marker dominate in all brain areas. The results demonstrate that EEG complexity is more sensitive to the natural level of blood biomarkers than the level of EEG power. The reported novel findings demonstrate that the EEG markers of healthy people are influenced by the natural levels of their blood biomarkers related to their everyday dietary habits. This knowledge is useful in the interpretation of EEG signals and contributes to obtaining information about people quality of life and well-being.

Forecasts about the aging trend of the world population agree on identifying increased life expectancy as a serious risk factor for the financial sustainability of social healthcare systems if not properly supported by innovative care management policies. Such policies should include the integration within traditional healthcare services of assistive technologies as tools for prolonging healthy and independent living at home, but also for introducing innovations in clinical practice such as long-term and remote health monitoring. For their part, solutions for active and assisted living have now reached a high degree of technological maturity, thanks to the considerable amount of research work carried out in recent years to develop highly reliable and energy-efficient wearable sensors capable of enabling the development of systems to monitor activity and physiological parameters over time, and in a minimally invasive manner. This work reviews the role of wearable sensors in the design and development of assisted living solutions, focusing on human activity recognition by joint use of onboard electromyography sensors and inertial measurement units and on the acquisition of parameters related to overall physical and psychological conditions, such as heart activity and skin conductance.

Authors: Liu Lina , Cai Chenning , Qian Zhenghua , Li Peng , Zhu Feng
Published: November 2024

When cracks appear in reinforced concrete (RC) structures, the tensile load will be borne by steel bars with high ductility, resulting in a large deformation. Traditional strain sensors have difficulties in achieving good performance for large deformations in concrete structures. In this paper, based on a laser-induced graphene (LIG) technique, a flexible sensor is proposed for monitoring large deformations of concrete structures. Polyimide film is used as the carbon precursor to prepare LIG through laser scanning and then LIG is transferred onto a polydimethylsiloxane (PDMS) substrate to form the flexible sensor. The calibration and performance verification of the flexible sensor are completed through tensile tests. The applicability of the flexible sensor in monitoring large deformations of concrete is verified through beam bending experiments. The fatigue resistance of the flexible sensor is verified through fatigue tests on a full-scale beam. The experimental results showed that the flexible sensor has the advantages of low cost, simple preparation, and stable performance, making it suitable for applications in the field of large deformation monitoring of RC structures.
Willingness to Pay for Domestic Waste of Rural Households Under Low-Carbon Society Transition: A Case Study of Underdeveloped Mountainous Areas in Shaanxi, China
Authors: Lu Siqi , Wang Feng , An Ruikun
Published: November 2024

A low-carbon society aims to achieve sustainable social development through innovative technologies and mechanisms, promoting low-carbon economic models and lifestyles. In light of China’s commitment to achieving carbon neutrality and transitioning to a low-carbon society, it is crucial to control waste generation at its source, as the waste management sector is highly polluting and contributes substantially to carbon emissions. Adopting the 3R (reduce, reuse, and recycle) approach, reducing the quantity of waste is the priority in waste management. Therefore, exploring rural residents’ willingness to adopt the “pay as you throw” (PAYT) policy in underdeveloped mountainous areas and the factors influencing this willingness is highly valuable. This paper adopts the Contingent Valuation Method (CVM) with a face-to-face questionnaire survey, involving 1429 farmers from six cities around the underdeveloped mountainous area in Northwestern China. It measures their willingness to pay (WTP) and preferred payment levels for the PAYT policy. Based on the theory of planned behavior, the paper finds that farmers’ environmental knowledge, environmental awareness and social trust positively influence their WTP, while farmers’ perception of pollution and daily waste disposal do not significantly impact their WTP. Additionally, social trust negatively moderates the relationship between environmental knowledge and WTP. This paper provides empirical results that can support the implementation of a nationwide waste fee management system and the promotion of volume-based waste fee management. It also offers targeted suggestions for the government to establish PAYT and improve the efficiency of rural household waste management in rural China.

Authors: Hanafy Anood M. , Abd-el-Malek Mina B. , Badran Nagwa A.
Published: November 2024

Due to its critical importance in engineering applications, this study is motivated by the essential need to understand natural convection over a vertical cylinder with combined heat and mass transfer. Lie group symmetry transformations are used to analyze the thermal and velocity boundary layers of steady, naturally convective laminar fluid flow over the surface of a vertical cylinder. The one-parameter Lie group symmetry technique converts the system of governing equations into ordinary differential equations, which are then solved numerically using the implicit Runge–Kutta method. The effect of the Prandtl number, Schmidt number, and combined buoyancy ratio parameter on axial velocity, temperature, and concentration profiles are illustrated graphically. A specific range of parameter values was chosen to compare the obtained results with previous studies, demonstrating the accuracy of this method relative to others. The average Nusselt number and average Sherwood number are computed for various values of the Prandtl number Pr and Schmidt number Sc and presented in tables. It was found that the time required to reach a steady state for velocity and concentration profiles decreases as the Schmidt number Sc increases. Additionally, both temperature and concentration profiles decrease with an increase in the combined buoyancy ratio parameter N. Flow reversal and temperature defect with varying Prandtl numbers are also shown and discussed in detail.

The level of the human body’s burden of benzophenone and camphor ultraviolet (UV) filters can be estimated from their urinary levels. The present study describes the implementations and validation of the sensitive analytical method for the analysis of seven benzophenone and two camphor UV filters in urine. Sample preparation includes overnight enzymatic hydrolysis and ethyl acetate extraction followed by purification by dispersive solid-phase extraction using a sorbent Z-Sep. For the analysis, ultra-high performance liquid chromatography coupled with tandem mass spectrometry was used. Validation was performed using a Standard Reference Material® 3673 and an artificially contaminated urine sample. Target analyte recoveries ranged from 79–113% with repeatability expressed as a relative standard deviation of 2–15%. The limits of quantification were between 0.001 and 0.100 ng/mL in urine. This method was subsequently applied to examine the urine samples collected from Czech women. The analytes benzophenone-1 and 4-hydroxy-benzophenone were the most common analytes present in 100% of the samples, whereas benzophenone-3 was quantified in only 90% of the urine samples. The other four determined benzophenone derivatives were quantified in ≤33% of the samples. The derivatives of camphor were not detected in any samples. This method could be applied in biomonitoring studies.

The article analyzes the place and role of stakeholders in the system of professional training of cultural studies. It was determined that among the general and professional competencies of the bachelor and master of cultural studies, the state standard of higher education in the specialty defines the ability to communicate in a foreign language, which directly affects the ability to use various sources of information, analyze cultural policy in foreign institutions. It is described how the training of specialists who are able to popularize knowledge about culture and disseminate information of cultural content, using modern information, communication tools and visual technologies among the international community, became one of the foundations of the educational and professional programs «Culturology» of the first (bachelor’s) and second (master’s) levels of higher education of Poltava National Pedagogical University named after V. G. Korolenko. It is characterized how this process is provided not only by the content of educational components from the cycle of general training, but also through the involvement of stakeholders in the process of developing, discussing, changing and revising educational programs and organizing courses of non-formal education, foreign language training and involvement in socio-cultural projects with territorial communities. It has been proven that mutual work on the training of a specialist in cultural studies, who not only possesses a wide range of modern cultural knowledge, but is also capable of effective interaction with members of the public, has been part of the activities of the Department of Cultural Studies, Philosophy and Museum Studies of the Poltava Pedagogical University since its foundation.

FORMATION OF CRITICAL THINKING IN THE SYSTEM OF COMPETENCE-BASED TRAINING OF SPECIALISTS
Authors: Usanova L. , Usanov I. , Shtepa O.
Published: November 2024

The article explores the philosophical and educational foundations of critical thinking formation in the professional training of future specialists. Critical thinking has become an important educational competence at the request of contemporary intellectual culture. The reasons for the importance of critical thinking in the knowledge society, as well as the philosophical and pedagogical tools for its formation, are considered.
The achievements of researchers in various fields (philosophy, psychology, pedagogy) concerning critical thinking in defining its essence and development opportunities are analyzed. The article shows how the definition and interpretation of critical thinking have changed with the shift of the educational paradigm and pedagogical (educational) model. The article also highlights the mutual influence of the social environment and information technology that leads to forming a «knowledge society». In a society where information and knowledge are becoming the determining resources, the skill of critical perception of information, independent analysis, and effective use of it are becoming more important. Therefore, mastering critical thinking is a task for the upbringing of a contemporary specialist who can think and act outside the box and effectively.
Critical thinking is viewed as an interdisciplinary concept since achieving this skill requires using information from various fields of knowledge. At the same time, attention is drawn to the philosophical foundations of the definition of critical thinking: reflective, meaningful, and justified. The role of philosophical disciplines in studying and teaching of critical thinking is indicated. The theoretical basis for the definition of critical thinking is the distinction between two ways of perceiving the world: subjective (non-reflective, unconscious, inattentive) and critical, i.e. reflective thinking, characterized by awareness of what is happening, attentiveness, ability to question, ability to distinguish between stereotypes, recognize manipulation, etc.
The analysis made it possible to identify the essential features of this concept, as well as to define critical thinking as conscious, independent, reflective, purposeful, well-founded, and self-organized. Among the tools for developing critical thinking, it is important to involve students in solving problems and dialogue, using interactive forms of learning and reflection on cognitive activity.

The article substantiates the pedagogical conditions of future coaches training for applying the sports selection technologies into professional activity. It is proved that the formation of future coaches’ readiness to apply sports selection technologies into professional activity should be conducted on the basis of compliance with the following pedagogical requirements: formation of positive professional motivation and a system of key values of the future coach with the help of anthropic technologies; development of technological thinking of future coach in the field of sports selection and orientation; integration of theoretical, scientific and research, and practical training in order to develop the professional readiness of the future coach; formation of a competitive and developmental educational space for the professional training of future coaches; implementation of facilitation support and mentoring technologies in the future coaches’ adaptation to professional activities.
It is established that the development of future coaches’ motivation is a complex process that includes educational training, psychological support, reflection and active participation in the professional environment. The development of technological thinking in the process of formation of the future coaches’ readiness to apply the sports selection technologies allows to create a positive emotional background for learning the educational material; to systematise the practice-oriented knowledge and use it in a complex; to transform the theoretical knowledge into the level of professional skills effectively; to instill the students with a certain type of communication (subject-subjective) in the process of educational tasks solving; to improve the level of professional training in general. The integration of theoretical, scientific and research, and practical training of future coaches in higher education institutions involves a combination of theoretical knowledge, research results and practical experience to form a comprehensive training of specialists for the application of sports selection technologies into professional activities. The implementation of this pedagogical condition will contribute to a deeper understanding of the material, the development of critical thinking and effective solution of practical problems in future professional activities. It is emphasized that during the facilitation of learning, the lecturer has the opportunity to use not dogmatic methods and techniques, but those that promote creative comprehension of the necessary information, the formation of the ability to think, to look for new aspects of problems in the already known material.

The subject of the article is to examine the reasons, methods and results of the communist regime control over the literary and artistic environment of the Ukrainian Soviet Socialist Republic (Ukrainian SSR) in 1920 describing the case of writer Borys Antonenko-Davydovych: surveillance of punitive bodies as one of the mechanisms of this process, in particular. On the basis of the materials of the State Political Administration, memoirs and other sources, the process of surveillance of B. Antonenko-Davydovych is partially reconstructed, and the main directions of surveillance are identified. Ukrainian writer B. Antonenko-Davydovych, like most famous writers of the 1920s, was under the supervision of the SPA, which collected information on him. However, the file against the writer was destroyed at the end of the USSR's existence, and therefore the possibilities for reconstructing the surveillance process are limited. Thus, other similar documents of the Soviet punitive authorities, such as the form file on H. Kosynka, documents from criminal cases that were started in 1930 against the literary and artistic intelligentsia of Ukraine, allow us to determine the main circle of people, events, and results of this surveillance. The case of the "Fugitives" is of particular importance, as it contains information on a group of writers who, according to the punitive authorities, were led by B. Antonenko-Davydovych and planned to leave Ukraine in early 1930 to avoid repression. Similarly, the context of the events is shown in the reports of the secret department of the SPA of the Ukrainian SSR of 1927-1929, which actually described and summarized the results of surveillance. To verify such complex sources as the documents of the Soviet secret services, ego-documents from the literary and student environment of the time - Dokiya Humenna, Hryhorii Kostiuk, and Oleksa Varava - were also used. From these sources it becomes clear that B. Antonenko-Davydovych was under surveillance in connection with his participation in the work of the provincial committee of the Ukrainian Communist Party (UCP), his activity in the student community in Kyiv, his participation in the literary organisations Mars and Lanka, and his work in the All-Ukrainian Film and Photo Department (AUFPD). The article shows how the materials of the SPA and NKVD of 1930, criminal cases and files depict the events of 1920 and confirm mass surveillance of the literary and artistic environment in the Ukrainian SSR. This surveillance provided dat for the punitive authorities to persecute and repress the writer in 1930. Key words: Borys Antonenko-Davydovych, literary and artistic intelligentsia, surveillance, writers, State Political Administration (SPA), controlled revival.

Buildings make up the highest energy consumption. The challenge of reducing energy consumption has been focused mainly on residential buildings. The economic constraints faced by both homeowners and new construction constitute other barriers in this area. The latest building materials and advanced technologies can overcome some of these barriers and facilitate the rapid progress of energy efficiency in the residential building sector. Glass fiber reinforced concrete is gaining increasing attention because it can help reduce energy consumption in the residential sector. This material has many additional benefits, such as durability, high strength and low environmental impact.This paper focuses on the changes that occur in glass fiber reinforced concrete from a mechanical and thermal point of view. Concrete samples are made strictly according to systemic standards and under careful experimental conditions. This rigorous process ensures reliability and accuracy. Our results provide concrete evidence of the benefits of using glass fiber in concrete. We found that the addition of glass fiber by 0% to 1% reduces the bulk density between 1% to 4.75%, increases the compressive strength from 3.2 MPa to 5.3 MPa with an increase of 65.6%, and reduces the value of thermal conductivity 2.6% to 9.5% while increasing thermal insulation by 14%. These findings underscore the importance of using fiber in the field of construction.

Truth and Art from Nietzsche's perspective
Authors: Chebbi Noureddine
Published: November 2024

This article aims to analyze Nietzsche's vision of the relationship between Truth and Art by focusing on how they are connected. Starting by questioning traditional perceptions of "truth", explaining its nihilistic traits and its antagonism to life, and critiquing the Platonic conception that diminishes the importance of art on the grounds of its connection with the sensible. Culminating in highlighting the aesthetic characteristic of the world from the perspective of an interpretative and vital space. Where the will to power is the source of all "meaning and value." Ending with exploring the fundamental role of tragic art in affirming life as it appears. An artwork is nothing but the mirror in which life itself is seen, and what is seen is that illusion and falsification are perspectival necessities for living beings preoccupied with preserving their survival, and that truths are nothing but beneficial illusions.
