Thermal Energy Storage (TES) is a technique that stores thermal energy, accomplished by changing the temperature of a storage medium, such as a phase change material (PCM), for later use in various applications, for example, heating and cooling or power generation. The heat energy that is saved is usually kept in the storage medium. This study investigates how the performance of the TES tank is affected by the ratio of length to diameter. The research focuses on how the ratio affects the convergence test while the PCM0 (water-ice) used in TES starts to release latent heat into the air. Five models were designed by using CATIA software and the analysis was conducted in ANSYS CFD software. Convergence tests were conducted to validate the accuracy of the obtained simulation results. Two additional criteria, namely temperature and ice mass fraction, were also analysed to evaluate the performance of the TES tanks. The investigation of the TES tank using five different models has shown that each model reaches a constant temperature of 0°C during the melting phase, but at different time intervals. Model 1 reaches this temperature the fastest, followed by Model 2, Model 3, Model 4, and finally Model 5. A model that reached the constant temperature first indicated a more efficient discharging process, as it signified a faster rate of ice melting and thermal energy release. In terms of ice mass fraction, Model 1 retained a significant amount of solid ice (0.9968), with noticeable melting. Model 5, on the other hand, showed minimal melting and better preservation of solid ice (0.9992). Considering temperature, ice mass fraction and ease of convergence, Model 1 performed the best, when the solidified PCM0 was melting faster while maintaining a substantial amount of solid ice in the TES tank. The present study was successfully developed and compared various TES configurations while satisfying the convergence criteria set in the simulation. To conclude with, the results showcase the performance differences based on pipe size. These discoveries contribute to refining tube-type TES tanks and their design for thermal energy storage systems.

The demand for lightweight and high-performance structures has driven the popularity of commercially available aluminum alloys such as AL6061, particularly in the transporterindustry. However, predicting stress distribution accurately within AL6061 frame structures under diverse loading conditions remains a significant challenge for clients due to the complex nature of their behavior. To address this challenge, a study has been conducted that utilizes the advanced 3D simulation software SolidWorks 2023 to model a custom dimension frame structure and evaluate their behavior under varied loads of up to 200% of the structure's weight, which is a significant departure from the standard loading conditions. The goal is to offer a thorough and accurate assessment of the frame structure's capabilities. This investigation analyzed the stress, strain, displacement, and safety factors of a specifically designed frame structure, ensuring that each value met or exceeded acceptable standards. This study also provides valuable insights into the structure's performance under various loading conditions, including the handling of heavy items and specimens that require the use of a transporter in industrial engineering applications. Additionally, a detailed assessment of the material properties of the aluminum alloy used in constructing the frame structure provides useful information for designing and optimizing high-performing structures in the industry. Based on the results, it appears that the critical von Mises stress, when exposed to maximum varying loads (76.54 MPa), remains below the structure's yield strength of 275 MPa. The equivalent strain reaches a maximum value of 0.5607E-03, and the structure's deformation at maximum loads is just 0.6705 mm. The safety factors of the structure, tested at three different varying loads, are above 3. These values conclusively demonstrate that the AL6061 frame structure is safe and reliable for industrial applications and can withstand loads up to 200% wt.

Welding is a commonly used process in manufacturing and engineering, and it may create residual stress in the welded region that can cause problems during service. Thermal expansion of the post-weld heat treatment (PWHT) of steel carbon induces residual stress. To relieve the internal stresses in the weld zone, PWHT is used to soften the hardening zone, improve microstructures, and lower hydrogen content in the welded region. The pipe size, heating width, insulation conditions, heating rates, soaking temperature, and holding time are factors that influence PWHT procedures. This paper will explain clearly about the PWHT process and the effect of PWHT on the metallic metal.

The formation of desiccation cracks has detrimental effects on the hydraulic conductivity that affects the overall mechanical strength of expansive soil. Qualitative analysis on the desiccation cracking behaviour of expansive soil provided understanding of the subject based on various concepts and theories, while quantitative analysis aided these studies through numerical supports. In this study, a machine learning technique in image processing is developed to evaluate the surface crack ratio of expansive soil. The desiccation cracking tests were conducted on highly plastic kaolinite slurry samples with plasticity index of 29.1%. Slurry-saturated specimens with thickness of 10 mm were prepared. The specimens were subjected to cyclic drying-wetting conditions. The images are acquired through a digital camera (12 MP) at constant distance to monitor the desiccation cracks. The images are then pre-processed using OpenCV before crack feature extraction. In this study, a total of 54 desiccation crack images were processed, along with 8 images from trial test to train the model. The processed images are used to quantify the desiccation cracks by evaluating surface crack ratio and average crack width. It was identified that the accuracy of the model for the quantification of surface crack ratio and average crack width were 97.24% and 93.85% respectively with average processing time of 1.51s per image. The results show that the model was able to achieve high accuracy with sufficient efficiency in determining important parameters used for crack characterization.

A vegetated channel refers to a form of infrastructure that aims to mitigate stormwater runoff through the utilization of either natural or constructed systems that replicate the behavior observed in natural environments. The condition of the vegetated channel has the potential to influence the hydraulic behavior of the channel. The regulation of stormwater quantity in the management of drainage systems is influenced by the characteristics of the vegetated channel. Field data was gathered from a channel located in the parking lot of the Faculty of Civil Engineering and Built Environment at the University Tun Hussien Onn Malaysia (UTHM) campus. The purpose of this data collection was to assess the influence of various sectional circumstances on the velocity profile. The measurement of stream flow velocity is conducted by the utilization of current meter equipment during field investigation. The Manning's coefficient for each section was analyzed to assess the impact of variations in this parameter on the flow rate of the channel. In accordance with the results obtained, the coefficient value of Manning's ranged from 0.160 to 0.826. The velocity offlow in the vegetated channel ranged from 0.003 m/s to 0.010 m/s. In the interim, the flow discharge magnitude for the channel exhibits variability within the range of 0.0005 m3/s to 0.002 m3/s. This study examines the impact of bed surface condition, channel slope, and Manning's coefficient on flow rate. Therefore, the flow rate and Manning's coefficient were found to be impacted by both the bed condition and the slope of the channel.

Authors: Pospekhov V. V.
Published: September 2024

The purpose of the research is to extend information across the distribution of zooanthroponotic helminth infections transmitted through freshwater fish in the Magadan Region.

Materials and methods. The study area is located in the Upper Kolyma basin on the Magadan Region and the Republic of Sakha (Yakutia) border. The Omulevsky Park is also located here, one of the clusters of the Chersky National Park named after A. V. Andreev. The existing lake and river systems (Darpir, Momontai, Malyk, Urultun and Ui) are inhabited by 7 fish species: Arctic char (Salvelinus alpinus), east-Siberian grayling (Thymallus arcticus pallasi), round fish (Prosopium cylindraceum), Siberian sucker (Catostomus catostomus rostratus), burbot (Lota lota leptura), common minnow (Phoxinus phoxinus) and sculpin from the Kolyma (Cottus kolymensis). 685 specimens of fish were undergone parasitological survey using established procedures. The found helminths were fixed in 70% ethanol and clarified in glycerol.

Results and discussion. In the study of the fish helminth fauna in the lake and river systems of the Upper Kolyma Highlands, three helminth species that posed a danger to humans and animals were identified, Dibothriocephalus dendriticus, D. ditremus (Diphyllobothriidae) and Eustrongylides excisus (Dioctophymatidae). Information was provided on fish infection with these parasites in the lake and river systems, and their distribution in the Magadan Region, and a brief description of these types of helminths was given. In domestic scientific and methodological publications, the problem of eustrongylidiasis as a zooanthroponotic disease is not sufficiently covered, therefore, emphasis is placed on nematodes of the genus Eustrongylides. The research results may attract the attention of sanitary and veterinary service specialists to this issue, especially given the creation of a national park in the Magadan Region. Data on the freshwater fish infection with Diphyllobothriidae in the Upper Kolyma Lake and river systems expand the diphyllobothriasis nosoarea in the Magadan Region and allows the Susumansky District to be included in its boundaries.

The purpose of the research is to apply molecular genetic research methods to identify the taxonomic affiliation of gastrointestinal parasitic sheep nematodes of the family Trichostrongylidae using nested PCR followed by the restriction fragment length polymorphism (RFLP) analysis.Materials and methods. Parasitic nematodes, L3 Strongylata larvae obtained from incubated fecal samples of sheep. The genomic DNA was isolated using a commercial kit for DNA extraction from micro-quantities of tissues (Synthol, Moscow) as per the manufacturer’s guidelines. For DNA amplification, a T-100 Bio-Rad thermal cycler and a commercial Eurogen Master Mix reagent kit were used. The PCR regime was performed according to the WAAVP guidelines, 2006. The restriction endonuclease Rsa I of amplified Trichostrongylidae fragments was performed according to guidelines of the enzyme manufacturer (Sibenzyme, Novosibirsk).Results and discussion. To determine the taxonomic affiliation of Strongylata larvae isolated after incubation of feces from sheep, molecular genetic studies were performed using nested PCR followed by the restriction fragment length polymorphism (RFLP) analysis. This method makes it possible to identify, with the least effort, the genotypes of three species of Strongylata Haemonchus contortus, Trichostrongylus colubriformis, and Teladorsagia circumcincta at the larval stage.

The article is related to the theoretical analysis and generalization of scientific information on the problem of tolerance to uncertainty in psychology and an empirical study of the relationship between a person's tolerance to uncertainty and a sense of satisfaction with life, psychological well-being, and the perception of one's life as existentially meaningful. It is noted that, despite the relatively long history of studying the phenomenon of uncertainty tolerance in science and its potential importance, there is still no scientifically based and agreed interpretation of this phenomenon in psychology, since it can be defined by different scientists as: 1) a personal trait / characteristic / property; 2) a social attitude of an individual, containing cognitive, affective and conative components and/or their combination, or 3) a holistic system of a person's response to a situation of uncertainty. It is stated that the essential reason for the emergence of a situation of uncertainty in a person's life is the lack of information necessary for an adequate understanding of the content and consequences of this situation; while this can be both the result of a real lack of the necessary data, and vice versa, it is emphasized by the excessive amount of information available to a person, which with its content and form of presentation (clip-fragmented) only makes it difficult to find the information necessary to solve the situation or its interpretation. As a result of our research, it was established: a person intolerant to uncertainty, understanding it and evaluating it negatively, can show dissatisfaction with his life; while a person who is tolerant of uncertainty tends to feel psychologically well-off with satisfaction and existential meaningfulness of his own existence. It was concluded that tolerance to uncertainty presupposes a person's ability to calmly / without internal tension relate to the lack of information needed in the situation, to accept the presence of an uncertain situation as a component and permanent content of one's own life; to allow the coexistence of contradictory and inconsistent information without a biased attempt to give preference to one part of it or to oppose it to another; the possibility (but not the obligation) to start actions aimed at solving / overcoming the situation of uncertainty, without being sure of their effectiveness; however, hoping to gain new experience and acquire life wisdom; to accept the existence of the uncertain in its various variants (as unknown (completely or partially), ambiguous (ambivalent or ambiguous), not yet resolved, or not resolved at all). However, neither tolerance nor intolerance of uncertainty is a uniquely positive or negative personality trait.
ДІАЛЕКТИКА ЗДОРОВ’Я: ПСИХОСОМАТИЧНИЙ АСПЕКТ

Published: September 2024

Проблема здоров’я, шляхів впливу на функціональний стан людини є однією з найскладніших комплексних проблем, яка охоплює філософський, культурологічний, медичний, біологічний, педагогічний, психологічний, валеологічний, соціальний та інші виміри сучасної наукової думки. Здоров’я як предмет дискусії науковців багатьох галузей знань є феноменом, в основі якого лежить складна взаємодія конфліктуючих між собою, іноді діаметрально протилежних протиборчих сил, квінтесенцією яких є діалектична єдність “хвороба-здоров’я”. Надавати хворобі лише негативного забарвлення, розглядати її як факт відсутності здоров’я і/або поразки організму в боротьбі за існування – надто спрощений підхід. Симптоми, як правило, віддзеркалюють намагання організму гармонізувати психосоматичні процеси, що зрештою, є виявом здорових сил. Ефективність оздоровлення визначається конфігурацією впливу на основі комплексного застосування різних засобів. Здоров’я як багатокомпонентна ієрархічна структура є наслідком дії величезної кількості різноманітних чинників. Маленькі, але правильно організовані резонансні впливи можуть бути досить ефективні. Цілеспрямований вплив на слабкі інформаційно-енергетичні структури дає змогу отримати результат за порівняно невеликих зусиль. Застосування оздоровчих засобів супроводжується стресовими (руйнівними) процесами, в результаті яких організм посилює свою резистентність. Будь-який оздоровчий процес є мистецтвом тримати рівновагу і баланс сил. Досліджуючи окремі компоненти процесів і явищ, сучасна наука з’ясовує окремі їх властивості, параметри, закономірності, але втрачає можливість їх аналізу як системи добре скоординованих і взаємопов’язаних взаємодій. Метою дослідження є аналіз теоретичного і практичного досвіду лікувально-оздоровчої сфери, який дає змогу наблизитися до розуміння феномену здоров’я, його суті, окреслення методологічних засад оздоровчої діяльності.
Magnetic property approach for identification of dominant crystal structure in AISI420 treated by RF-DC Plasma N2-H2

Published: September 2024

The nitridation of RF-DC plasma N2-H2 into AISI420 produces several phases namely α' (bcc), ε (hcp), and γ (fcc) which are randomly distributed in a number that is difficult to identify. So the most dominant justification of crystal phase was needed. Based on the concept of isothermal transformation of AISI420 transformed from the α’ phase (ferromagnetic), to ε phase (paramagnetic), and to γ phase (nonmagnetic). It can be used as the underlying theory that magnetic property approach can potentially identify the dominant crystal phase. This study measured the magnetic properties of AISI420 treated by RF-DC plasma N2-N2 for identification of dominant crystal structure. Based on the hysteresis curve (M-H loop) of VSM method, magnetic characteristics can be produced such as susceptibility. Furthermore, the atomistic simulations were performed with the LAMMPS. Modelling of schematic picture of the structure using VESTA v.3.3.2 64 bit. Susceptibility value of AISI420 treated with RF-DC Plasma N2-H2 is range in the notation of 10-5 to 10-3, so it meets criteria of 10-5 < 10-3 which can be categorized as paramagnetic and super-paramagnetic. It has the dominant ε-Fe3N phase with trigonal-hcp microstructure based on magnetic property approach and simulations of LAMMPS and VESTA.
