The results of experiments on ablation of several grades steel targets — high-carbon steel (97 % Fe, 1.3 % C), low-carbon steel (97 % Fe, 0.3 % C) and stainless steel AISI 304, scanning beam of nanosecond laser pulse are given. The dependence of ablation depth ∆h and ablation energy efficiency ηE on intensity in the range q = 2·108 – 7·108 W/cm2 has been determined. It has been established, that during carbon steels targets ablation the mechanism of explosive boiling (phase explosion) is realized, for characterization of which the concept of “explosion force” Pe is introduced. The Pe value is the ratio of the change in the target material volume having removed ΔV to the pulse energy ΔE at the point of the Dh(q) dependency curve with the maximum rate of ablation depth growth. The values Pe are given, calculated according to graphs Dh(q), as well as the values determined according to published data for various materials (Al, Si, Ni). The range of the values of “explosion force” is Pe = (1.35 – 30)·106 mm3/J, i. e. the maximum and minimum values differ by more than an order of magnitude, with Pe values calculated for a given material depending on the duration of tp pulse, which seems to be with the penetration depth of the thermal wave deep into the target material. As for the results of our experiments, in high-carbon steel target irradiation, Pe values are only slightly lower than the maximum values obtained when irradiating Al and Si targets, and for low-carbon steel — close to the minimum values. The dependence of ablation depth on the pulse interval is determined. It has been established that the nature of the curve of this relationship is determined by the change in the concentration of micro- and nanoparticles, which are formed by the action of previous laser pulses and absorb the energy of the laser pulse having irradiated.

The article considers methodological aspects of using compacts (pressed samples) to study surface tension, wetting, and a number of other important colloidal-chemical properties of polymineral powders, including those subjected to mechanical activation. The effect of changes occurring with materials during pressing is investigated, and recommendations are developed for making pressed samples to measure surface tension. Compacts from mechanically activated quartz-containing polymineral powder of varying degrees of dispersion were made by pressing under pressure from 15.9 to 707.4 MPa. Surface tension (polar and dispersion components), color coordinates, and strength properties were determined for the obtained samples. It is shown that there are functional dependencies between the characteristics under consideration and the duration of grinding, as well as the pressing pressure. For the first time, the nature of changes in the polar component of the surface tension of mineral powders during their mechanical activation and pressing (compact production) was established. A feature of pressing finely dispersed powders has been revealed, consisting in a decrease in the values of the surface tension indicator (due to a denser packing of particles in samples and, as a result, the formation of a large number of Van der Waals bonds), while for coarsely dispersed powders an increase in its values is observed due to the crushing of brittle grains of minerals and, as a result, the formation of new active centers occurs. Based on the determination of the surface tension of mineral powder systems using compacts, recommendations have been developed for their manufacture to avoid possible errors in measuring the surface tension of the original mineral powders.

The organic-inorganic hybrid material (OIH) copper iodide-polypyrrol (CuI-PPy), obtained by a one-pot method in aqueous mixed solutions of precursors, was used as a bacteriostatic and bactericidal media agent on Escherichia coli BB culture in an aqueous nutrient medium. The addition of OIH material (1 mg/ml) into culture media suppressed the growth of E. coli for 60 hours, after which the efficiency of bacteriostatic action was more than 80%. The use of CuI-PPy as an additive to the paint coating leads to the death of bacteria after 1 hour of contact of the bacterial cells solution with glass plates coated with modified CuI-PPy paint coatings. After 12 hours of contact, the bactericidal effect of the CuI-PPy modified film remains unchanged. The advantages of using CuI-PPy material in comparison with CuI are discussed.

Experimental studies of the influence of mechanical deformation during the polymerisation process of ED-20 epoxy resin on the mechanical properties of cured specimens. Measurements of mechanical stress-strain dependence and ultimate strength were carried out in automatic mode using the Devotrans BP D NU testing machine. Experimental measurements of the mechanical stress-strain dependence for the samples subjected to stretching during polymerisation allow us to conclude that the ultimate strength of the cured samples increases by 1.5 to 2.5 times depending on the degree of stretching and the stage of polymerisation at which the stretching was carried out. At the same time, the Young’s modulus of the cured specimens changes insignificantly. This effect can be exploited in the manufacture of epoxy resin products, including composites based on epoxy binders.

Influence of starting material preliminary preparation and gaseous medium composition on adsorption and microstructural characteristics of activated carbons (AC) obtained from cotton fluff by two-stage microwave heating was investigated. Cotton fluff samples were impregnated with a 5 % solution of H3PO4, molded in the form of cylinders without incisions (type I), in the form of cylinders with transverse incisions (type II), and in the form of cylinders made of crushed “fluff–crumbs” (type III). During two–stage microwave heating (the first stage is carbonation in Ar, CO2 or N2 for 60 s, the second is activation in air for 50 s), fluff samples are completely carbonized and activated. It was found that the two-stage process allows to achieve higher rates of adsorption capacity of the finished AC according to the methylene blue indicator compared with single-stage microwave heating for 120 s. It is shown that by incising or grinding the processed samples, the adsorption capacity can be further increased. The reasons for the higher adsorption capacity of carbonized type III samples are higher density uniformity due to the grinding of the starting material, which makes it possible to achieve higher carbonation temperatures in a steady state (up to 1100 °C in a CO2 environment). Grinding also leads to additional surface development both due to the dissection of the fiber into several fragments, and due to the stratification of the fiber wall during the carbonization process.

This study aims to develop composites using electrically conductive carbon and polymer polyethylene (LLDPE) to enhance electrical conductivity. Investigations have been conducted on the fabrication of electrically conductive composites and the modulus of elasticity through heat compaction using mixtures of carbon-LLDPE powders. Heat compaction is performed at temperatures ranging from 120°C to 150°C, with varying composition ratios of carbon-LLDPE, including 50:50, 60:40, and 70:30 % wt. Higher proportions of carbon and compaction temperatures are correlated with increased electrical conductivity. For instance, the C7-3LLDPE composite, compacted at 150°C, demonstrates the highest electrical current flow of 0.0018 A, whereas the C5-5LLDPE composite, compacted at 135°C, exhibits the lowest current flow at 0.0000638 A. Regarding the modulus of elasticity, the composition ratio of C7-3LLDPE, compacted at 120°C, achieves the highest value at 2686.43 [N/mm2 ]. Conversely, the composition ratio of C5-5LLDPE, compacted at 135°C, yields the lowest modulus of elasticity at 1530.94 [N/mm2 ]. Elasticity modulus testing follows the ASTM D638 standard, with a speed of 2 mm/min. It is observed that increasing the compaction temperature results in a decreased modulus of elasticity across all composition ratios. Furthermore, a higher carbon content within the composite corresponds to a higher modulus of elasticity, regardless of the compaction temperature.
The Influence of Al-Ti-B on the microstructure of unidirectionally solidified Al-10wt.%Cu-10wt.%Si

Published: November 2024

Many works have reported the role of grain refiners in aluminumsilicon alloy casting in direct chill casting. However, only a few are under the unidirectional solidification condition. Direct chill casting favors equiaxed structures, while unidirectional solidification favors columnar structures. This work investigated the influence of Al-Ti-B on the microstructure of unidirectionally solidified Al-10wt.%Cu-10wt.%Si. The samples were directionally solidified using the Bridgman apparatus. It was cooled at the bottom to a temperature of 650℃, and the temperatures were recorded during the cooling. A representation of the cooling curve was selected, and the solidification parameters were calculated. Metallographic procedures were applied to observe the microstructure across the sample length. The results show that the 0.03wt.%Ti effectively promotes nucleation in many sites. It leads to the formation of equiaxed structures and prevents fine columnar structures from further growth. Due to the magnitude of the cooling rate, the 0.03wt.%Ti exhibits fine columnar, fine equiaxed, coarse equiaxed, and dendrite equiaxed structures at the separated distance from the contact area. This formation is in line with the one produced by the mechanism in direct chill casting. Understanding the grain refiner effect is crucial for optimizing manufacturing processes and achieving desired material properties. The Al-Ti-B addition is not recommended in the propeller manufacturing industry.

Published: November 2024

Supercapacitors have emerged as a crucial energy storage technology, bridging the gap between traditional capacitors and batteries. The performance of supercapacitors is heavily dependent on the properties of the electrode materials used. Mechanical processing methods, particularly High Energy Milling (HEM) and High-Velocity Particle (HVP) methods have shown great promise in enhancing the physical and electrochemical properties of supercapacitor materials. This review explores the fundamental principles, mechanisms, and recent advancements in HEM and HVP techniques for the synthesis and modification of supercapacitor materials. High energy milling, including ballmill and attritor milling, facilitates particle size reduction, increased surface area, and the creation of nanostructures, leading to improved capacitance and energy density. High velocity particle methods, such as cold spraying and thermal spraying, enable the deposition of uniform and dense coatings, enhancing conductivity and stability. The review also discusses the impact of process parameters on material properties, the challenges faced in scaling up these techniques, and the potential future directions for research. By providing a comprehensive overview of these mechanical processing methods, this paper aims to highlight their significance and potential in advancing supercapacitor technology.

Published: November 2024

The low quality of the thermodynamic process in a gas turbine power plant results in the waste of potential energy and impacts the power plant's efficiency. Analysing the thermodynamic performance of a gas turbine power plant is crucial to evaluating its efficiency in converting fuel energy into useful work. This analysis helps identify opportunities for improvement and optimise the plant's design for better performance by examining the components (e.g., the compressor, combustion chamber, and turbine). This study aims to evaluate the performance of a Gas Turbine Power Plant (GTPP) through thermodynamic analysis considering the variation of cycle loads. The study was conducted based on the field survey data obtained from the GTPP PT PLN Belawan generation implementation unit. The collected operation data was used to perform a thermodynamic analysis by applying the principles of conservation of mass and energy, along with the laws of thermodynamics. The study examined five cycle load variations: 31.7 MW, 34.3 MW, 48.1 MW, 60.7 MW, and 71.7 MW. Results showed a consistent reduction in the gas turbine heat rate as the load increased, with a significant 53.3% drop in heat rate from 34.3 MW to 71.7 MW. Higher cycle loads also correlated with increased turbine and compressor work, with the turbine producing 55.8% more work than the compressor at 71.7 MW. The turbine's thermal efficiency ranged from 40% to 44%, with potential for a 5% efficiency increase.

Published: November 2024

Type 2 diabetes mellitus is a chronic disease with a high global prevalence, so efforts to reduce the prevalence of this disease are needed. This study aims to evaluate the role of psychological distress as a moderator in the relationship between perceived seriousness and adherence to diabetes management. A total of 107 type 2 diabetes patients aged 26-82 years participated in this study, with a percentage of women of 74.8%. This study is a cross-sectional study with a correlational research type that will measure the relationship between three variables, namely psychological distress, perceived threat, and adherence to diabetes management. The measuring instruments used are Perceived Seriousness, General Health Questionnaire-12, and Diabetes Activity Questionnaire. Data were processed using regression techniques with PROCESS v4.0 to see the moderation relationship between variables. The results of the moderation analysis showed that psychological stress significantly moderated the relationship between perceived seriousness and adherence. This study found that higher psychological distress was associated with a weaker relationship between perceived seriousness and compliance, whereas higher psychological distress strengthened the impact of perceived seriousness on compliance.

Published: November 2024

Mental health disorders are highly heterogeneous, presenting diverse symptoms, risk factors,and treatment responses. Identifying distinct subgroups within these disorders is essential fordeveloping personalized treatment strategies, improving therapeutic outcomes, andoptimizing resource allocation. This systematic review explores how cluster analysis has beenapplied in mental health research to categorize subgroups across various psychiatric andpsychological populations, evaluating its implications for personalized care and addressingkey methodological challenges. A comprehensive literature search of PubMed, PsycINFO,Scopus, and Web of Science (October 2021 to October 2024) yielded 31 studies that usedcluster analysis to identify subgroups within disorders such as depression, PTSD, anxiety,schizophrenia, BPD, ADHD, and OCD. In alignment with the study’s objectives, dataextraction focused on clustering methodologies, subgroup characteristics, and the clinicalimplications for treatment personalization. Studies employed a range of clustering techniques,including K-means, hierarchical clustering, latent class analysis, Gaussian mixture models,and DBSCAN, which effectively identified clinically meaningful subgroups characterized byunique symptom profiles, biological markers, and treatment responses. For instance,melancholic, atypical, and anxious subtypes in depression were identified, each requiringtailored therapeutic approaches. Similarly, biomarker-based subgroups in generalized anxietydisorder emphasized the potential for targeted interventions. This review affirms that clusteranalysis is a valuable tool in precision psychiatry, offering insights into disorderheterogeneity that support the development of individualized treatment plans and improvepatient outcomes.Keywords: Cluster analysis, mental health, subgroup identification, personalized care,systematic review, precision psychiatry
From ‘Isolation’ to ‘Me-Time’: Linguistic Shifts Enhance Solitary Experiences
Authors: Rodriguez Micaela , Campbell Scott W.
Published: November 2024

Spending time alone is a virtually inevitable part of daily life that can promote or undermine well-being. Here, we explore how the language used to describe time alone—such as “me-time” “solitude,” or “isolation”—influences how it is perceived and experienced. In Study 1 (N = 500), participants evaluated five common labels for time alone. Descriptive and narrative evidence revealed robust interindividual variability and significant mean differences in how these labels were perceived. Overall, “me-time” was rated most positively, and “isolation” was rated least positively (but not negatively). In Study 2, we experimentally manipulated the linguistic framing of time alone, describing it as either “me-time” or “isolation”. Participants (N = 176) then spent 30 minutes physically alone, without digital interaction. Notably, positive affect increased for participants in the “me-time” condition but decreased for those in the “isolation” condition. Negative affect decreased for both conditions, but the magnitude of the decrease was larger after “me-time”. Additionally, linguistic framing affected what people thought about, but not what they did, while alone. People’s beliefs about being alone improved after “me-time” but not after “isolation.” These findings demonstrate meaningful variation in how people perceive different labels that refer to time alone and suggest that simple linguistic shifts may enhance subjective experiences of time alone.

Published: November 2024

To effectively tackle loneliness in youth, prevention and intervention strategies should be based on solid evidence regarding risk and protective factors in this age group. This systematic literature review identifies and narratively synthesizes longitudinal studies of risk and protective factors for loneliness in children and adolescents aged below 25 years. A systematic literature search was conducted in October 2023 using PsycINFO and MEDLINE, resulting in k = 398 articles, with k = 105 articles meeting the inclusion criteria. The examined factors included demographic (e.g., gender), socio-economic (e.g., income sufficiency), social (e.g., peer acceptance), mental health (e.g., depression), physical health (e.g., disabilities), health behavior (e.g., sport participation), and psychological factors (e.g., shyness). Additionally, adverse childhood experiences (e.g., child maltreatment) and environmental factors (e.g., neighborhood characteristics) were investigated. Despite the wide range of potential risk and protective factors examined, relatively few studies provided strong evidence for a prospective association with loneliness. Risk factors that were consistently identified across multiple longitudinal studies included low peer acceptance and peer victimization, depression, social anxiety, internalizing symptoms, low self-esteem, shyness, and neuroticism. Additional replication is required to evaluate factors that have shown significant associations with loneliness in only a limited number of longitudinal studies (e.g., aggression).

This literature review contrasts microeconomic fertility models during the demographic and post-transitional periods, evaluating their implications for macroeconomic growth models. While microeconomic fertility models stress the trade-off between child quality and quantity during the demographic transition, the extensive and intensive margin fertility model applies to the post-transition period, with implications for childlessness and the postponement of childbearing. The impact of micro decisions on economic growth is more substantial during the demographic transition than in the post-transition period. Low or negative population growth during the post-transition period may stall economic growth.

Bogotá es la sexta ciudad más poblada de América Latina, cuenta con una población aproximada de 7,4 millones de personas y una extensión de 1775 km2, según el censo del DANE para 2018 (SDP, 2020). Esta ciudad, al ser una de las más grandes en la región necesita un sistema de transporte competente para movilizar a sus habitantes; sin embargo, tras cuatro décadas de propuestas en la actualidad carece de un sistema de trenes urbanos o metro, y, sólo hasta el año 2020 se comenzaron a desarrollar fases previas a la construcción, bajo los lineamientos del contrato firmado entre Empresa Metro de Bogotá y la empresa Metro Línea 1 S.A.S. Debido a lo anterior, en este trabajo se busca describir las posibles razones de carácter económico que han influenciado a los proyectos más significativos de este sistema de transporte en la capital durante casi 40 años, hasta la puesta en marcha de la Primera Línea del Metro de Bogotá (PMLB), esto mediante una revisión de los diferentes estudios que se realizaron desde 1981 hasta 2020 para la construcción del mismo.

AbstrakHarta oleh sebagian manusia dianggap sebagai barang yang sangat berharga sehingga sering menimbulkan perselisihan untuk mereka berebut atau menguasai harta warisan tersebut. Sengketa harta waris ini bisa membawa dampak buruk bagi para ahli waris yang ditinggalkan, karena berebut harta waris tersebut, hubungan kekeluargaan diantara ahli waris bisa rusak atau dapat memutuskan tali persaudaraan diantara mereka. Pada masyarakat sekarang, banyak orang Islam yang tidak lagi menggunakan sistem pembagian harta waris menurut syari’at Islam. Hal ini tentunya kurang sesuai dengan apa yang telah diajarkan oleh Rasulullah SAW. Selain itu penentuan siapa saja yang berhak mendapat harta waris juga banyak masyarkat yang bleum paham, kemudian tata cara pembagiannya masih menggunakan pihak ke 3 atau orang lain yang dianggap pakar dan masih dilakukan dengan cara manual. Berdasarkan permasalahan tersebut, penulis membuat aplikasi Sistem Pakar Pembagian Harta Waris Menurut Hukum Islam Berbasis Android. Teknik pengumpulan data yang digunakan adalah wawancara dan studi pustaka. Aplikasi ini diharapkan dapat membantu masyarakat khususnya mereka warga muslim dalam menentukan pembagian harta warisan. Untuk membuat program ini penulis menggunakan metode Forward Chaining. Aplikasi ini terdiri dari 4 menu utama yaitu hitung waris, info waris, tentang dan keluar. Kata kunci: Harta Waris, Forward Chainning, Android AbstractAssets by some people are considered very valuable items so that it often causes disputes for them to fight over or control the inheritance. This inheritance dispute can have a bad impact on the heirs who are left behind, because of fighting over the inheritance, family relations between the heirs can be damaged or can break the ties of brotherhood between them. In today's society, many Muslims no longer use the inheritance distribution system according to Islamic law. This is certainly not in accordance with what has been taught by the Prophet Muhammad. In addition to determining who is entitled to inherit property, many people do not understand, then the distribution procedure is still using 3rd parties or other people who are considered experts and is still done manually. Based on these problems, the author makes an Android-Based Android-Based Application for Inheritance Distribution Expert System. Data collection techniques used are interviews and literature study. This application is expected to help the community, especially Muslim citizens in determining the distribution of inheritance. To make this program the author uses the Forward Chaining method. This application consists of 4 main menus, namely calculating inheritance, inheritance information, about and exit.Keywords: Property Inheritance, Forward Chaining, Android
