Abstract
Heavy rare earth elements (HREE), as critical materials for the global transition to a low-carbon economy, are mostly supplied by regolith-hosted ion adsorption deposits formed from the weathering of granites. Magmatic-hydrothermal titanite of pronounced HREE enrichment in granites has been suggested to play an important role in forming HREE-dominated regolith-hosted deposits. However, the crystal-chemical mechanism and geological process responsible for HREE enrichment in titanite remain unknown. This study investigated two texturally distinct types of HREE-enriched titanite (titanite I and II) in granites from the Gucheng regolith-hosted HREE deposit in South China. Secondary ion mass spectrometry (SIMS) U-Pb dating of rutile associated with titanite I and II yielded similar ages of 101.0 ± 1.7 Ma and 97.9 ± 6.2 Ma, respectively, supporting HREE remobilization during auto-metasomatism. Microbeam synchrotron X-ray absorption spectroscopic analyses show that titanite I and II have distinct Y K-edge X-ray absorption near-edge structure spectra. The best-fit results of Y K-edge extended X-ray absorption fine structure data suggest that titanite I and II have a Y-O first shell with coordination numbers and distances of 7.8 and 7.2 and 2.31–2.51 Å and 2.30–2.47 Å, respectively. Measured Y 3d and Dy 3d X-ray photoelectron spectroscopic data also support different Y,HREE-O first shells between titanite I and II. These results suggest that Y3+ and REE3+ occupy the 7-coordinated Ca site via three substitutions (Y,REE)3+ + (Al,Fe)3+ ↔ Ca2+ + Ti4+, 2(Y,REE)3+ + □Ca ↔ 3Ca2+, and 2(Y,REE)3+ + O2− ↔ 2Ca2+. First-principle calculations and the lattice strain model predict preferential uptakes of Y3+ and HREE3+ as the (Y,HREE)O8 polyhedra arising from the latter substitution mechanism at the Ca site in titanite. Also, we link the 2Y3+ + O2− ↔ 2Ca2+ substitution in titanite to highly oxidized and HREE-enriched melts/fluids originating from the subducted slab. These findings further support our previous suggestion that the crystallization of HREE-enriched titanite in granites plays an important role in forming HREE-dominated regolith-hosted deposits.

Authors: Sandoval- Rodríguez, et. al. C. L. 
Published: January 2025

Piezoelectric materials can be used in applications designed to handle a wide range of input frequencies and forces to enable energy harvesting. Although several studies have been carried out on piezoelectric energy harvesting systems, this application is still under development. The purpose of this work is to analyze the behavior and the ability to generate electrical energy through the elements in piezoelectric tiles or platforms, specifically, piezoelectric disc elements with a diameter of 27 mm. To do this, a platform of about 130 x 75 cm was designed to capture the footsteps of people and transmit the impact force to sensors to determine the power generation capacity of the piezoelectric elements. Tests were carried out with people weighing between 75 kg and 85 kg and the measurements obtained made possible to identify the behavior of the system and to develop a mathematical model to estimate the energy generated through the platform.The piezoelectric elements used here proved to be fragile despite the different types of shock absorbers used to avoid their rupture. Therefore, it is recommended to delve into the design of protection mecha-nisms to extend the life of piezoelectric elements in energy collection systems.

Technological development is considered one of the most important influences that contributed to the change of some design elements (formal and functional), both or each. Among these elements is the mina-ret. This was evident in the old urban fabric, and because of the existence of other basic reasons in the tradi-tional fabric, including the increase in the population of the weaving area, which led to the dispensation of the inner courtyard. It had changed from an element that has a shape and function to an element that has a shape only, to indicate the presence of a mosque this was evident in the old urban fabric .Due to the pres-ence of other essential causes in the traditional fabric like the increase in population among the inhabitants of the fabric which led to neglecting the internal area , moreover climate change led to the use of window openings as outlets for air conditioning instruments ,the researcher employed the minaret to enable sunlight inter the inner space of the mosque (prayer space) due to the importance of natural sunlight effect on peo-ple's psychological and physiological health . This research was conducted in a clear sky of Babil province for latitude of (32.8) north, small samples were made measuring 1:20 for the minaret and the mosque space, a device for measuring the sunlight amount (Multi-Function Environment Meter 4IN1) was used . Results showed an increase in natural sunlight reflected inside the space of the mosque. This study came out with the following recommendations, the importance of employing the archeological elements which their func-tions were altered by technological growth to enhance the internal environment with the finding of solutions to the amount of harmony in distributing sunlight (distributing natural sunlight harmoniously )

Published: January 2025

In this study, three types of aerofoils were examined at various angles of attack and at a steady value then fluctuated of air flow. Then, the findings were compared to the XFOIL prediction results. The experimental and simulation results were consistent to some extent with the XFOIL prediction results. The shape of the chosen aerofoils was modified by making a slot through the blade the aerofoil and studying their effect on the aerodynamics of the modified shape. The slotted aerofoil shape was studied as it faced a fluctuated wind flow. The results revealed that the increase in angles of attack, the lift force increased and approximated its maximum value and then began to decrease with the slot. During the calculations, a case study for the number of elements was done to obtain the best mesh. The experimental and simulations were conducted by using ANSYS CFD at Reynolds number 106 and AOA equals (0°, 4°, 8°, 10°, 12°, 15°, 16°, 17°, 18°) for three shapes of aerofoils which are without a slot, two of which are symmetrical, NACA 0012 and NACA 0015, and one asymmetrical, which is NACA 4415. The slotted aerofoil (existence of an opening after 40% from the leading edge) which is the NACA 0015 aerofoil, was simulated.

Published: January 2025

The method of reinforcement soil layers was a common technique to improve the ability of the soil to retain load and reduce settlement. The technique has been somewhat dependent, whereas, in the past, there was research on this method of design and analysis. So, soil improvement by reinforcing it must be analyzed correctly. The capacity of assuming the improved bearing capacity underground of reinforced sand was in-vestigated through the user's use of the test executor in diverse test cases. Here in this investigation, four various kinds of reinforcement materials have been used. Four circular models with different interior diame-ters were used to examine the effect of the circular ratio on the bearing capacity of the soil layer along the various reinforcing state of affairs. A typical plate load test was carried out with the presence of monotonous and periodic loading in three chains mentioned in tests of the monochrome plate loading on ringing base anchoring on layers of sand which are reinforced over Netlon CE121 Geo-grid as a material of reinforce-ment- 15 numbers, tests of periodic plate-load PLT along Geogrid (Netlon CE121) as materials of reinforc-ing - 15 number, the Monochromatic tests of plate-load over Geojute as a reinforcing material - 9 number, tests of periodic plate-load PLT over Geojute as a reinforcing material - 9 number.

Authors: Ali, et. al. Noora Jamal 
Published: January 2025

The concept and growth of superior individualized healthcare technologies are influenced in significant ways by the rising areas of “Artificial Intelligence (AI) and the Internet of Things (IoT)”. Most people use wearable devices for mHealth, hence there are many potential applications for the “Internet of Medical Things (IoMT)”. Only 5G can provide the necessary support for smart medical devices to perform many different types of demanding computing activities. Today, heart disease was the major mortality on a global scale. For patients who need a greater accurate diagnosis and treatment, the advancement of medical innova-tion has created new obstacles. Although many studies have focused on diagnosing cardiac disease, the find-ings are often inaccurate and fail to fulfill patients' expectations of quality of service (QoS). So, this paper introduces a novel “feed-forward Bi-directional long-short term memory (FF-Bi-LSTM) algorithm to predict heart disease more accurately with enhanced QoS in IoMT based on 5G”. Linear discriminant analysis (LDA) and min-max normalization are employed, respectively, for preprocessing and feature extraction. Several measures, including precision, recall, accuracy, and f1-score, are used to the assess effectiveness of the suggested strategy. The proposed method also compared to certain existing techniques. These results show that the suggested strategy outperforms existing strategies in terms of improving QoS.
Idősödő társadalom az idősek arányának növekedése nélkül

Az elmúlt két és fél évtizedben Magyarország népessége számottevően idősödött. Nőtt a medián életkor és a 65 évesek és idősebbek aránya a népességben. Ebben az idősödő népességben azonban nem nőtt az idősnek tekinthetők aránya, mert az aktív életszakasz és az időskor határa jelentősen felfelé tolódott: emelkedett a munkaerőpiac elhagyásának átlagos életkora (másként: az effektív nyugdíjkorhatár vagy kilépési életkor). Olyannyira, hogy a mindenkori átlagos kilépési életkorban hátralévő várható élettartam nemhogy nem nőtt, hanem kifejezetten csökkent. Bár a 65 év felettiek aránya emelkedett, azok aránya, akik a mindenkori effektív korhatárnál idősebbek, gyakorlatilag változatlan maradt. A magasabb aktív életkorokban várható élettartam általános növekedését a munkaerőpiac gyakorlatilag teljes mértékben felszívta. E folyamatok akkor zajlottak le, amikor a korhatárra érők iskolai végzettség szerinti összetétele jelentősen megváltozott. A ma nyugdíjba vonulók lényegesen iskolázottabbak, mint a két és fél évtizeddel ezelőttiek voltak, mivel a mai 55–64 évesek számottevően hosszabb időt töltöttek az iskolapadban, mint azok, akik negyedszázada voltak 55–64 évesek.
Numerical and field investigation to improve an existing distributed-sediment-excluder sand trap performance
Authors: Mc Leod Claudia , Bosman Adèle , Smit Francois 
Published: January 2025

ABSTRACT

Sand traps are essential for managing sedimentation in irrigation systems, ensuring the efficiency and longevity of water infrastructure. This study addresses the underperformance of the Lower Usuthu Smallholder Irrigation Project (LUSIP) sand trap in the Usuthu River basin, eSwatini, where sediment build-up disrupts its operational efficiency. Field investigations and advanced numerical modeling using ANSYS Fluent, the study evaluates the trapping and flushing efficiency of the sand trap. A fully coupled 3D numerical model simulates hydrodynamics and sediment transport, focusing on flow velocity and suspended sediment concentration distributions under both maximum design discharge and low-flow conditions. Field investigations revealed a trapping efficiency of 27% and a flushing efficiency of 36% during low-flow conditions, primarily due to turbulence and design limitations. Numerical simulations identified critical sediment deposition patterns and flow dynamics, leading to design recommendations. With the proposed modifications, the sand trap's trapping efficiency is projected to increase to 85%, while flushing efficiency is expected to reach 80% under low-flow conditions. This study introduces innovative modeling approaches to assess three-dimensional flow dynamics in distributed-sediment-excluder systems, offering actionable insights for optimizing sediment management in irrigation infrastructure. These findings contribute to sustainable agricultural development and water resource management, addressing challenges in semi-arid regions.

Published: January 2025

Introduction. The article substantiates an individually and socially significant problem that is relevant to different educational systems and countries: the recent forced transition to distance learning. Distance learning is a set of educational services, which is provided through a special information and educational environment. The current study aims to investigate the attitude of ethnic Armenians and Russians to distance learning during that affected psychoemotional condition of personality.
Methods. The study investigated the experience from distance learning in students from Russia and Armenia (N = 185, M age = 21.98, SD age = 5.73). The study was conducted using State-Trait Anxiety Inventory (S-Anxiety scale) and authors’ questionnaire to assess distance learning experience.
Results. The majority of Armenian and Russian students mentioned advantages of distance learning, such as they found it convenient, were satisfied and had adequate home conditions for learning. However, some disadvantages were mentioned including the difficulty of the objective assessment of their knowledge in distance learning context. Statistical analysis allowed to observe relationship between the anxiety level and students’ experience with distance learning, i.e., the adaptation level and the satisfaction value. Additionally, the association between adaptation level and the country of residence was found along with the determinants of distance learning effectivity.
Discussion. The study revealed the main trends in students’ perception of distance learning on the territory of Armenia and Russia. We showed the association between psychoemotional features and assessment of distance learning.

Introduction. The article is devoted to the analysis of strategies for overcoming difficult life situations of men and women with alcohol addiction. Due to the current need to revise the concepts of rehabilitation measures and psychological impact on persons belonging to the addictive category of the population, we have developed and implemented a program of group sessions with patients and evaluated its effectiveness.
Methods. The study was conducted among 120 respondents in the Lugansk Republican Narcological Dispensary: 60 patients with I-II stages of chronic alcohol addiction (30 men and 30 women), as well as 60 employees of the medical institution without alcoholism in the anamnesis (30 men and 30 women). The method of psychological testing and psychodiagnostic tools were used: Test "Overcoming Difficult Life Situations"; "Coping Behavior Questionnaire"; "Stress Susceptibility Questionnaire"; "Level of Subjective Control Questionnaire"; Michigan Alcohol Screening Test. The group psychocorrectional sessions were aimed at increasing the level of expression of adaptive strategies for overcoming difficult life situations in men and women with alcohol addiction, along with the reduction of dysfunctional and maladaptive behavioral strategies; increasing the level of internality of the locus of personality control, as well as reducing the severity of stress and actualization of resources for its overcoming.
Results. Addictive men prefer to engage in confrontation with others with a clear sense of self-pity. Women are oriented towards obtaining effective and emotional support and delegating personal responsibility. Psychocorrectional group sessions contribute to the manifestation of active and goal-oriented strategies of effective resolution of difficulties. The increase of self-control, acceptance of responsibility, as well as the decrease in susceptibility to stress with the increase in internality of the personality are resources for the formation of constructive behavior of alcohol-addicted patients.
Discussion. The externality of the addicts control locus and low stress resistance indicate a variant of the destructive manifestation of personal resources. The formation of a cognitive and practical basis for functional strategies is possible through a comprehensive rehabilitation process.

Published: January 2025

Introduction. The article explores the characteristics of adolescent deviant behavior in online communities. This study is the first to examine the specific role dispositions of adolescents prone to online deviance. We analyzed the mechanisms through which real-world personalities transform in the digital environment, leading to the development of both normative and deviant digital identities. Our research focus was on teenagers, as they represent the most vulnerable group, with their value systems undergoing reformation in the real world while their new social experiences are shaped online.
Methods. In the study, which involved a survey of 158 adolescents in both real and virtual spaces, the following methodologies were used: "Propensity for bullying in the Internet space" (Luchinkina, 2019); individual personality orientation diagnostic methodology (modified by N.P. Fetiskin); locus of role conflict diagnostic methodology by P. P. Gornostai.
Results. Adolescents with an egoistic orientation are more prone to engage in online deviant behaviors such as harassment. Conversely, adolescents with a cooperative orientation are less likely to exhibit deviant behaviors, including verbal insults, harassment, disclosure of personal information, threats of physical violence, and social isolation. The desire for new online experiences, combined with a reduced interest in real-life interactions, contributes to both socially acceptable and deviant online roles. In contrast, adolescents with a marginalized orientation are more likely to engage in deviant behaviors such as harassment, insults, using fake names and profiles, social isolation, disclosing personal information, and making threats of violence. Furthermore, a correlation has been established between the locus of role conflict and specific forms of online deviant behavior.
Discussion. Cultural factors play a significant role in shaping individual online behavior patterns, influencing attitudes, values, and behavioral responses. Online activity can range from normative to deviant, with each influencing cognitive processes and online behavior.
