- MakaleYalnız künye2026Scopus SJRQ2Hydrodynamic characterization and design evaluation of a conical spout–fluidized bed under geometric and gas-distribution effects
Çutay, Arif; Tozlu, Alperen; Özahi, Emrah
Spout–fluidized beds are widely used in gas–solid processing and thermal conversion applications because of their enhanced particle circulation, mixing, and heat-transfer characteristics. However, the combined effects of reactor geometry, distributor configuration, and gas-flow distribution on the hydrodynamic organization of conical spout–fluidized beds are still not sufficiently quantified from a design perspective. In this study, a three-dimensional transient numerical analysis was performed to assess the effects of cone angle, auxiliary-hole number, and auxiliary-to-total flow-rate ratio on gas–solid flow behavior in a conical spout–fluidized bed reactor. The simulations were carried out using an Eulerian–Eulerian two-fluid model coupled with the kinetic theory of granular flow and the Syamlal–O'Brien drag model. Three cone angles (50°, 60°, and 70°), three distributor configurations with 70, 140, and 210 auxiliary holes, and two auxiliary-to-total flow-rate ratios (Qf/QT≈0.15 and Qf/QT=0.43) were investigated. The hydrodynamic response was evaluated using particle velocity, voidage distribution, and two compact flow indices: the radial spout heterogeneity index (RSHI) and the axial spout regularity index (ASRI). The results show that the flow field is governed by a characteristic core–annulus structure consisting of a dilute, high-velocity spout core and a denser recirculating annulus. Increasing Qf/QT enhances auxiliary gas penetration, particle suspension, and radial expansion of the gas-penetrated region; however, it also increases RSHI and ASRI, particularly at lower cone angles, indicating stronger radial heterogeneity and axial irregularity. Increasing the cone angle from 50° to 70° reduces radial hydrodynamic heterogeneity and improves axial spout regularity, whereas the number of auxiliary holes has a secondary and configuration-dependent influence compared with the gas-flow distribution and cone angle. Overall, the findings indicate that the auxiliary-to-total flow-rate ratio primarily controls gas distribution and gas–solid momentum exchange, while the cone angle governs radial uniformity and axial spout regularity. The proposed RSHI–ASRI framework provides a design-oriented basis for comparing conical spout–fluidized bed configurations and selecting operating conditions according to the desired balance between gas–solid interaction intensity, radial uniformity, and axial spout regularity.

Çınar, Öznur; Cengiz, Ekrem
This study aimed to perform a cross-cultural adaptation of the English version of the Personalized Psychological Flexibility Index into Turkish (T-PPFI). It was conducted among 604 disaster search and rescue volunteers who participated in the 2023 Kahramanmaraş earthquakes in Türkiye. Exploratory factor analysis supported a three-factor, 15-item structure, and confirmatory factor analysis indicated good fit for the three-factor model. Convergent and divergent validity were supported by a positive correlation with the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (CompACT) and negative correlations with the Acceptance and Action Questionnaire-II (AAQ-II) and the Depression Anxiety and Stress Scales-21 (DASS-21). The T-PPFI showed acceptable internal consistency (total score α= .727; ω= .712) and high test-retest reliability over 14 days (r= .962). Gender measurement invariance analyses supported comparability of T-PPFI scores across men and women. Hierarchical regression analyses provided evidence for the incremental validity of the T-PPFI beyond AAQ-II and CompACT in predicting DASS-21 outcomes, and higher-order EFA supported construct-level discriminant validity. The findings suggest that the 15-item T-PPFI is a reliable and valid measure of psychological flexibility in Turkish disaster search and rescue volunteers. All rights reserved.
- MakaleYalnız künye2026Scopus SJRQ1Experimental 4E analysis (energy-exergy-economic-environmental) of hybrid parabolic trough collector-thermoelectric generator-phase change material cogeneration system
Guclu, Tamer; Cuce, Pinar Mert; Cuce, Erdem
Hybrid solar cogeneration systems are critical for enhancing energy utilisation and mitigating the intermittency of solar resources. This study presents a comprehensive 4E (Energy-Exergy-Economic-Environmental) experimental analysis of a novel hybrid system that uniquely integrates a Parabolic Trough Collector (PTC), a small-scale steam turbine, a Thermoelectric Generator (TEG) assembly, and a Phase Change Material (PCM) thermal storage unit. The system's performance was investigated under 15 distinct operating conditions, varying initial water masses (0.1, 0.15, 0.2 kg) and operating pressures (6, 8, 10, 12, and 14 bar). Experimental results demonstrated the system's adaptive cogeneration capabilities. At 14 bar and 0.2 kg, the system achieved its maximum Solar-to-Electricity efficiency of 0.42%. At this operating condition, the highest collector thermal efficiency was 25.25% (at 6 bar), and the maximum overall energy and exergy efficiencies were 8.43% and 1.45%, respectively. A key finding was the system's adaptive electrical output: at low pressures (6 bar), the TEG acted as a crucial co-generator, supplying up to 55% of the electricity, whereas at high pressures (14 bar), the turbine dominated, accounting for 88-90% of the output. Furthermore, the study experimentally confirmed that latent heat transfer was the dominant heat transfer mechanism for the PCM, with latent heat contributing ∼445 kJ (55%) of the 805 kJ total energy stored. The thermo-economic analysis confirmed the system's viability, yielding a Simple Payback Period (Spp) of 6.9 years and a competitive Levelised Cost of Energy (LCOE) of $0.101/kWh. The system is projected to save 118.8 kg of CO2 and 660 L of water annually. The results validate the thermodynamic and economic feasibility of the integrated PTC-Turbine-TEG-PCM concept as a flexible solution for small-scale solar cogeneration.

Water is a significant element for the sustainability of life and is crucial for many aspects, such as agriculture, cities, ecosystems, industries, and people. This study focuses on municipal water quality assessments for urbanization activities and human health concerns when dealing with the sustainable city concept. For the first time, an integrated fuzzy decision-making framework is proposed to evaluate municipal water quality criteria with microbiological parameters, heavy metals, and other chemicals. For this aim, the eight main criteria and forty-four sub-criteria were specified to evaluate municipal water quality for a sustainable city. A case study was performed in Bayburt, Türkiye, to evaluate 130 water depots when dealing with a number of scenarios. Moreover, the Sustainable Development Goals (SDGs) 6.1 and 6.3 can be achieved through the study. Finally, this study presents how to develop safe and clean water management for the concept of a sustainable city.

Ayberkin, Doruk; Yirik, Emirhan
This pilot study examines pre- to post-test changes in university students’ financial literacy knowledge following a one-week student-directed learning period using a pedagogically scaffolded GPT‑4o Application Programming Interface (API) chatbot. Guided by constructivist learning theory [29], the immediate feedback model [10], and self-determination theory [24], the study employed a single-group pre-test–post-test quantitative design with 32 undergraduate students at a Turkish public university. The primary outcome was financial literacy knowledge, measured with 32 factual statements rated on a six-point agreement scale and keyed against correct responses, across six subscales (Basic Economics and Finance, Individual Banking, Retirement and Insurance, Financial Statements, Investment, and Tax and Legislation). Five objective multiple-choice items served as a limited, complementary performance check. Paired-samples t-tests were used for normally distributed difference scores, and Wilcoxon signed-rank tests for non-normal difference scores; six subscale comparisons were interpreted using Holm-adjusted p values. The overall score increased from pre-test to post-test, with a large standardized mean change (d = 1.09, 95% CI [0.64, 1.52]), and all six exploratory subscale comparisons remained statistically significant after Holm adjustment. Objective item performance also increased on several items, including the compound-interest item (3.1% to 81.2%). However, because the design included no control or comparison group, identical objective items were repeated, and chatbot interaction logs were not systematically recorded, the observed changes cannot be causally attributed to the chatbot. The findings therefore provide preliminary, uncontrolled evidence that warrants testing in controlled studies rather than evidence of intervention effectiveness.

Anlar Daldal, Pınar; Öztürk Doğan, Hülya; Cinar Topcu, Kübra
In this study, silver nanoparticle-decorated iron cobalt sulphide (Ag@FeCoS₂) nanostructures were synthesized on the surface of a pencil graphite electrode (PGE). The resulting modified electrode obtained was used to determine the nitrite content in four different meat products (pastırma, bologna-type sausage, heat-treated sucuk, and ham) sourced from the same brand and widely consumed in the Turkish market. The fabricated Ag@FeCoS₂ electrode demonstrated high performance in amperometric nitrite detection, with a linear detection range (0.1 to 2.5 mM), high sensitivity (1759 μA mmol/L), and a low detection limit (0.29 μmol/L). The nitrite results obtained by the electrochemical method showed recoveries ranging from 99.3% to 102.5% compared with the spectrophotometric method. In addition, the physicochemical properties of the meat products, including pH, moisture, protein, fat, and ash contents, were characterized as complementary information on the real food matrices analyzed. Statistically significant differences were observed among the investigated products for these parameters. Overall, the developed Ag@FeCoS₂/PGE sensor provides a practical, accurate, and reliable analytical approach for nitrite determination in processed meat products.

Koroglu Kaba, Nagihan; Taskiran Eskici, Gülcan; Tiryaki Sen, Hanife
Perceived organizational support is an important organizational resource that may shape nurses' psychological well-being, workplace engagement, and performance-related outcomes. This study examined the relationship between perceived organizational support and nurses' job performance and explored whether burnout and quiet quitting showed indirect associations consistent with mediation. A cross-sectional correlational study was conducted in a tertiary university hospital in the Black Sea Region of Türkiye. Of 980 eligible nurses, 439 responded (response rate: 44.8%); after excluding 14 questionnaires, 425 nurses were included in the final analysis, representing 43.4% of the eligible population. Data were collected using standardized instruments measuring perceived organizational support, burnout, quiet quitting, and individual work performance. Descriptive statistics, Pearson correlation analysis, and multiple mediation analysis using Hayes' PROCESS macro were performed. Perceived organizational support was positively correlated with job performance (r = 0.27, p < 0.001) and negatively correlated with burnout (r = −0.47, p < 0.001) and quiet quitting (r = −0.37, p < 0.001). Burnout (r = −0.31, p < 0.001) and quiet quitting (r = −0.31, p < 0.001) were negatively correlated with job performance. The total effect of perceived organizational support on job performance was significant (b = 0.23, β = 0.27, p < 0.001). The direct association between perceived organizational support and job performance remained significant even after accounting for burnout and quiet quitting (b = 0.10, β = 0.12, p = 0.025). Significant indirect associations were observed through burnout (b = 0.07, β = 0.08, 95% CI = 0.03–0.12) and quiet quitting (b = 0.06, β = 0.07, 95% CI = 0.03–0.09). These findings suggest that supportive organizational environments may be associated with higher job performance among nurses by reducing burnout and quiet quitting. Given the cross-sectional design, these findings should be interpreted as associations consistent with mediation rather than causal evidence. The study was conducted in a single tertiary university hospital in the Black Sea Region of Türkiye, which may limit generalizability to other settings.

Ergin, Ayda Nur; Öztürk, Mesut; Aydin, Tuba Ağirman
This study examines preservice elementary mathematics teachers’ problem-posing processes related to vectors in space. Adopting a qualitative case study design, the problem-posing process was analyzed by treating the phases of orientation, connection, generation, and reflection as analytic units, focusing on the cognitive, linguistic, and reasoning-based actions exhibited at each phase. The findings reveal that preservice teachers experience considerable difficulties in establishing meaningful connections between mathematical structures and real-life contexts, particularly when posing vector problems in three-dimensional environments. In addition, causal attribution processes became salient during the reflection phase, with participants frequently explaining their successes and difficulties by referring to their conceptual understanding, prior experiences, and perceived competence. The results offer implications for the design of theory-based learning environments that support problem-posing processes in mathematics teacher education, particularly for advanced mathematical topics.

Dagci, O.; Tozlu, A.; Berber, A.
The primary parameters in wastewater treatment plant applications are pollutant removal in compliance with standards and energy costs. This study conducts exergy, exergoeconomic, and optimization analyses on the Konya Wastewater Treatment Plant to enhance its energy efficiency. All assessments of the plant were based on actual operational data. Numerical calculations were executed using Engineering Equation Solver software. Exergoeconomic analyses were performed using the Specific Cost Method, while optimization calculations employed the Net Present Value approach. Thermodynamic calculations revealed that the exergy efficiency of the biogas engine was 30.8%, which increased to 39.8% when integrated into a cogeneration system. The overall exergy efficiency of the plant was calculated to be 35.3%, which rose to 58.6% when stabilized sludge was utilized as fuel. During the optimization phase, various drying systems were evaluated, and a hybrid greenhouse-solar-panel drying system was identified as the optimal model. The analyses indicated that the total cost was minimized at the maximum dryness value (70%), suggesting that the greenhouse-type drying system could achieve regional conditions. Compared to thermal and solar energy systems, hybrid systems have been observed to offer significant advantages in first-year costs. Optimization studies reveal that hybrid systems provide 41% greater cost savings in initial investment and operational expenses compared to thermal systems, and 29% greater savings compared to solar energy systems. Meeting the system's energy demand with fossil fuels results in annual emissions of 76,850 tons of CO₂ and 1500 tons of harmful pollutants, equivalent to removing 19,000 cars from traffic or preserving 7300 hectares of forest. Significant soil and ecosystem degradation also occurs. The use of solar energy substantially reduces these environmental impacts, improving air quality and conserving natural resources.

This study systematically investigates the influence of scandium (Sc) additions at 0.1, 0.2, and 0.3 wt.% on the melt quality, microstructural characteristics, fluidity, and mechanical performance of A356 aluminum alloy under recycling-oriented casting conditions. The alloy charge consisted of 20% primary aluminum and 80% recycled scrap, while the Fe content was maintained at 0.2 wt.%. Melt treatment was performed by rotary degassing using a commercial flux. Melt quality was assessed using the Reduced Pressure Test (RPT) and bifilm index analysis, whereas casting performance was evaluated through an eight-channel fluidity test. Mechanical behavior was characterized by tensile and Brinell hardness testing, and microstructural and phase analyses were conducted using scanning electron microscopy (SEM) and X-ray diffraction (XRD). To complement the experimental investigation and provide a thermodynamic basis for interpretation, phase stability, solidification behavior, and phase-fraction evolution were examined using Thermo-Calc within the CALPHAD framework. By combining experimental characterization with computational thermodynamic analysis, this study elucidates the effect of Sc content on the processing–microstructure–property relationships of recycled A356 alloys and provides a systematic basis for evaluating Sc modification in high-recycled-content aluminum castings.

Ongan, Serdar; Kuziboev, Bekhzod; Makhmudov, Samariddin; Matyakubova, Aziza; Imamoglu, Ilyas Kays; Aydin, Rahman; Isik, Cem
Energy vulnerability is a critical concern for achieving energy security and meeting the SDGs. However, the role of economic complexity, which represents a country's production and export diversification, in energy vulnerability has been largely neglected in the literature. This study fills this gap by examining the impact of economic complexity on energy vulnerability for 69 developing countries over the period 2000-2019. For this purpose, MMQR and various instrumental variable (IV) estimation techniques (IV-Quantile, 2SLS, Lewbel, and Kiviet) were used. In addition, ESG indicators were included in the model as instrumental variables to address potential endogeneity issues between economic complexity and energy vulnerability. In doing so, the ESG indicators are also included in the model as instrumental variables to control for the endogeneity of economic complexity. Empirical findings show that economic complexity is associated with lower energy vulnerability across all quantiles. These results reveal that countries with diversified economic structures (higher economic complexity) may be more resilient to energy shocks. Therefore, developing countries should focus on structural reforms and improve their ESG performances to reduce energy vulnerability. In terms of control variables, financial development, digitalization, and human capital are associated with lower energy vulnerability, whereas increases in natural resource revenues are sometimes associated with lower vulnerability levels. This finding suggests that, in the context of energy vulnerability, the predictions of the resource curse theory may not be observed in every case.

Isik, Cem; Ongan, Serdar; Aydin, Rahman; Imamoglu, Ilyas kays
To achieve the SDGs, in addition to environmental (E), social (S), and governance (G) indicators, economic components should also be evaluated holistically. In this context, this research aims to test the time series characteristics of the indicators in the ECON-ESG structure, which is created by integrating the economic dimension into the ESG framework for Germany. For this purpose, linear and nonlinear structures, Fourier-based stationarity tests, and Bai-Perron multiple structural break tests were employed to examine the linear and nonlinear structures, stationarity cases, and structural breaks of various ESG and economic indicators (ECON). Findings show that many indicators are nonstationary, undergo structural changes over time, and exhibit nonlinear dynamics. The results indicate that sustainability policies should focus not only on indicator levels but also on the behavioral patterns and vulnerabilities of these indicators over time. In this regard, policymakers need to develop a holistic perspective on the economy and ESG, focusing on long-term and flexible policy designs. The study also offers important implications for how the ECON-ESG framework can serve as a model for both national and international markets, particularly in Germany, a developed and leading country in terms of sustainability. Therefore, the proposed ECON-ESG framework offers both theoretical and practical roadmaps for policymakers, firms, and investors to create long-term ESG strategies in support of the SDGs.

Ongan, Serdar; Özdemir, Dilek; Imamoglu, Ilyas Kays; Isik, Cem
Conflicts in controlling or using natural resources, arising from geopolitical risks (GPR), which have become a new normal today, can damage natural ecosystems and threaten sustainable development. In this context, GPR can turn the positive impact of supporting independent variables on sustainable development (SD) into a negative one. This research investigates the moderating effects of GPR on SD through renewable energy consumption (REN) and economic complexity (EC) in 25 oil-producing countries with relatively higher oil-reserve-related risks between 2000 and 2021. The panel quantile regression analysis reveals. (i) While using REN individually improves SD in countries with high SD (in the 80th and 90th quantiles), this improving effect turns to a worsening effect due to its interaction with GPR, which shows the moderating impact of GPR. (ii): While EC individually improves SD across all quantiles, these improving effects persist in countries with low SD (in the 10th, 20th, 30th, and 40th quantiles) even when complexity interacts with GPR, showing that GPR has no moderating impact on SD. Therefore, policymakers should investigate why the interaction of REN with GPR worsens SD in highly sustainable countries and redevelop regulatory renewable energy policies accordingly.

Novel heteroaromatic compounds (Hc1, Hc2, Hc3, Hc4) were obtained, and their structure were confirmed using various spectroscopic methods, including elemental analysis, fourier transform infrared (FT-IR) spectroscopy, proton and carbon nuclear magnetic resonance (1H/13C-NMR) spectroscopy, and molar conductance measurement. The biological activities of the heteroaromatic compounds against several Gram-positive (Micrococcus luteus ATCC9341, Staphylococcus epidermidis ATCC12228, Bacillus cereus RSKK863, Listeria monocytogenes ATCC 19111), and Gram-negative bacterial strains (Pseudomonas aeruginosa ATCC27853, Klebsiella pneumonia ATCC27853, Enterobacter aerogenes ATCC51342, Salmonella typhi H NCTC9018394, Shigella dysenteriae NCTC2966, Proteus vulgaris RSKK96026) were evaluated using the well-diffusion method. In general, the heteroaromatic compounds demonstrated a stronger inhibitory effect against Gram-positive bacteria. Hc1, Hc2 and Hc3 showed the highest inhibitory effect against B. cereus and L. monocytogenes. The compound (Hc4) showed the highest antibacterial activity and antifungal activity against Bacillus cereus and C. albicans, respectively. The cytotoxic activity of the heteroaromatic compounds was assessed against the non-small cell lung cancer cell line (NCI-H460) using the NutriCulture Cell Viability Detection Kit-8 (CVDK-8). Among the synthesized heteroaromatic compounds, Hc3 exhibited significant cytotoxic activity with an IC50 value of 141.3 & micro;g/mL, whereas compounds Hc1, Hc2, and Hc4 did not display significant toxicity at the tested concentrations. The molecular geometry of the heteroaromatic compound (Hc3) was optimized using Gaussian 09 W at the B3LYP/6-311++G (d,p) level of theory. Key structural parameters such as bond lengths, bond angles, and dihedral angles were determined through the same computational framework. Electronic features, including frontier molecular orbitals, global reactivity descriptors, and molecular electrostatic potential surfaces, were analyzed to explore intramolecular charge distribution and predict reactive sites. To evaluate the biological potential of the heteroaromatic compound (Hc3), molecular docking studies were performed. Additionally, drug-likeness assessment based on Lipinski's Rule of Five and ADME profiling revealed favorable pharmacokinetic characteristics. Molecular docking studies revealed that compound Hc3 showed a binding energy of -4.09 kcal/mol against the EGFR target (PDB ID: 1UWH), exhibiting key interactions such as hydrogen bonding and It-interactions with the active site residues. Based on all the results, it can be said that new heteroaromatic compounds have significant potential in the pharmaceutical field.

Yildiz, Tugba; Devecı, Fatma Gorgün
This study aims to determine the effect of consumer minimalism on sustainable consumption and to reveal the mediation effect of perceived consumer effectiveness. The research sample consisted of 1010 consumers aged 18 and above. Structural equation modeling and Process Macro were utilized in data analysis. According to the findings “clutter removal” and “longevity” have an effect on “perceived consumer effectiveness”. Perceived consumer effectiveness has an effect on “rethinking”, “reusing”, “refurbish”, “reuse” and “repurpose”. Further, “clutter removal” and “cautious shopping” has a direct effect on “rethinking”, “refurbish” and “reuse”. “Longevity” has a direct effect on “reusing”, “refurbish” and “repurpose”. Finally, “self-sufficiency” has a direct effect on “rethinking”, “refurbish" and “repurpose”. Mediation effects have been revealed by adding the “perceived consumer effectiveness” variable to the direct effect model for the “clutter removal” and “longevity” dimensions.

Emir, İlknur
The Hittite civilization existed in Central Anatolia between 1650 and 1200 BCE, with its capital in Hattusa. This polytheistic society attributed symbolic meanings to unexplained natural phenomena. They showed reverence to sacred beings through worship. The symbols created in Hittite art were not only aesthetically crafted but also believed to be iconic and venerated. Archaeological excavations have uncovered sun discs from the Hittite period, which are key to understanding their religious beliefs and cultural practices. These discs highlight the significance of the sun cult and the historical legacy of the Hittites. Each disc features unique designs, with distinct formal and symbolic traits. This study examines their meanings and formal features, shedding light on their cultural and religious importance.
