    The impact of the Dark Triad personalities and parental interaction patterns in predicting the tendency toward risky behaviors among adolescent girls in Ardabil, Iran in 2024

    Motavalli, Roya; Shayeghi, Hanieh; Mousazadeh, Tavakkol; Apay, Serap Ejder; Aktaş, Elif Odabaşı

    Background: The escalating prevalence of risky behaviors during adolescence has emerged as a grave threat to public health, posing one of the most significant psychological, social, and health-related challenges globally. These behaviors impact the individual and have negative consequences on families and society. As a pressing concern for communities, healthcare organizations, and social policymakers, identifying factors leading adolescents toward risky behaviors is paramount and urgent. Methods: This descriptive correlational study was conducted in Ardabil, Iran, in 2024. Using convenience sampling, 200 s-year high school girls with an average age of 17 were selected. Participants were asked to complete three questionnaires: the Dark Triad Personality Test, the Revised Family Communication Patterns Scale (RFCP), and the Questionnaire of Risky Behaviors (QRB). The data were analyzed using Pearson correlation and multiple regression analysis, utilizing SPSS version 20. Results: The findings revealed a significant positive correlation (p < 0.01) between machiavellianism, narcissism, psychopathy, and the conformity interaction pattern with a tendency toward risky behaviors in adolescents. Additionally, there was a significant negative correlation (p < 0.01) between the conversation interaction pattern and risky behaviors. The results further indicated that 30.4% (p < 0.01) of the variance in risky behavior tendencies in adolescent girls could be explained by the Dark Triad personality traits. In comparison, the interaction patterns of conversation and parental conformity could account for 37% (p < 0.01). Conclusions: This study suggests that the Dark Triad personality traits and parental interaction patterns can effectively predict adolescent girls’ tendencies toward risky behaviors. These results underscore the need for effective management strategies addressing these variables in school programs to provide early interventions that may prevent the escalation of risky behaviors among adolescents.

    The Effect of Cannabidiol on Myokine, Cerebral and Cardiac Response in Rats with Sepsis Induced by Cecal Ligation and Punture Method

    Erkiliç, T. Orkun; Bayraktar, B.

    Background: The aim of this study was to investigate the effects of Cannabidiol on myokine (Irisin), cerebral (BDNF) and cardiac (cTnI) responses in sepsis-induced rats by Cecal Ligation Perforation (CLP) method. Methods: In this study, 40 adult male Wistar albino rats, aged between 8-10 weeks, were used. 5 groups were created, with 8 rats in each group: Control (C), Sham (S), CLP, CLP+CBD 2.5 mg/kg, CLP+CBD 5 mg/kg group. Rats in groups C and Sham were sacrificed at the end of the 10th hour and intracardiac blood was taken immediately afterwards. In groups CLP, CLP+2.5 mg/kg, CLP+5 mg/kg, intra-abdominal sepsis was induced and at the end of the 10th hour after sepsis occurred with CLP application, rats were sacrificed and intracardiac blood was taken immediately afterwards. İrisin, BDNF and cTnI levels in the serum samples were measured by ELISA method. Result: In the present study, mean serum irisin, BDNF and levels were determined to be at the lowest level in the CLP group, while cTnI levels were at the highest level (p<0.01). In CLP groups, serum irisin and BDNF levels increased due to CBD addition and the most significant decrease in cTnI levels occurred in 5 mg/kg CBD groups. As a result, it was concluded that CLP may be safe and beneficial when administered at a dose of 5 mg/kg in sepsis-induced rats.

    Anlar Daldal, Pınar; Öztürk Doğan, Hülya; Cinar Topcu, Kübra

    In this study, CuCo₂O₄-rGO nanostructures were synthesized by a one-pot electrochemical method on the surface of Pencil Graphite Electrode (PGE) for nitrite determination in pastırma, a traditional meat product. The developed modified electrode was used to determine the amount of nitrite in pastırma samples obtained from three different brands in the Turkish market. When the nitrite values obtained by the electrochemical method were compared with the spectrophotometric method, they showed 91.20 % to 100 % agreement. In addition, the physicochemical properties of pastırma samples, such as pH, moisture, protein, fat, and ash, were analysed, and it was determined that pH and moisture values are critical parameters for product quality. These results show that the developed electrode provides a practical and sensitive method for nitrite sensing.

    Electrospinning Encapsulation of Chlorophylls Microwave-Extracted from Spinach Waste and Utilization as Coloring Agent in Yogurt

    Isik, Beyza Sukran; Bayram, Sinan; Altay, Filiz

    Natural colorants have become a developing market because of consumer preferences, and more cost-effective and stable production is necessary. In the present study, a natural green colorant was obtained via microwave-assisted extraction from spinach waste to produce affordable, environmentally-friendly, and innovative colorants. The extracts were encapsulated with zein via uniaxial and coaxial electrospinning techniques to overcome the stability issues associated with their natural green color. The encapsulation efficiencies of uniaxially encapsulated chlorophyll extracted from spinach waste by microwave were 63.50 and 57.18 for chlorophyll a and b, respectively. The efficiencies of chlorophyll a and b by coaxial electrospinning were found 49.53% and 88.58%, respectively. The microwave-assisted extraction and the addition of eumelanin may contribute positively to the antioxidant activity and thermal stability of electrospun samples. The stability test against light revealed that 61% of chlorophyll a could be preserved by uniaxial electrospinning. In addition, when chlorophyll-loaded nanofibers were incorporated into yogurt, a more stable green color was achieved during storage.

    Effects of Formaldehyde Scavenger on Mechanical, Physical, and Emission Test Results in Multi-Layer Pressed Chipboard Production

    Çamlibel, Osman; Peker, Hüseyin; Ayata, Ümit; Ulay, Göksel

    This study investigates the effects of different formaldehyde scavenger (FS) ratios on the physical, mechanical, and chemical properties of fiberboard composites. Experimental analyses included measurements of thickness, density, modulus of rupture (MOR), modulus of elasticity (MOE), internal bond strength (IB), shear strength (SS), moisture content, thickness swelling (TS), water absorption (WA), and formaldehyde emission (FE) levels. The results indicate that an increase in the FS ratio leads to a significant decline in mechanical properties. Specifically, MOR, MOE, and IB values decreased by 17.97%, 15.65%, and 16.33%, respectively. Changes in TS and WA were also observed, with TS increasing by up to 22.68% and WA decreasing by as much as 16.90%. In terms of formaldehyde emissions, a significant reduction was observed as the FS ratio increased. At a 15% FS ratio, formaldehyde emissions decreased by 43.24%, which is considered a positive outcome in terms of environmental and health impacts. Overall, the use of FS in specific ratios reduces FE while causing certain reductions in mechanical properties. These findings highlight the importance of optimizing FS usage for the production of low-FE fiberboards.

    Experimental performance assessment of two-stage thermoelectric system in a closed-cycle drying process

    Osta, Muhammet Harun; Yakut, Kenan; Köksal, Hüseyin

    Traditional drying systems suffer from several limitations, including high energy consumption, insufficient hygienic control, and the inability to maintain precise temperature regulation. Although alternative drying systems have been developed to address these issues, they often encounter practical challenges due to their complex structures and the need for numerous external components. To overcome these limitations, this study proposes and experimentally evaluates a novel, independently operating, two-stage thermoelectric module (TEM) system integrated into a closed-loop drying setup that eliminates the need for external heating and dehumidification components. The proposed system addresses the efficiency and hygiene problems observed in conventional dryers by simultaneously performing air heating, cooling, and dehumidification functions through compact thermoelectric devices. The drying process consists of two stages: the first involves air pre-conditioning (heating/cooling), while the second is dedicated to dehumidification. The performance of the system has been evaluated based on key metrics such as cooling and heating capacities, the coefficients of performance (COP) for both stages, moisture removal rate (MRR), and moisture removal rate effectiveness (EffMRR). Experimental studies were conducted under input voltages ranging from 3 to 7 V, relative humidity levels between 60 % and 90 %, and varying airflow rates. Under 90 % relative humidity conditions and a 7 V input voltage, the system achieved a maximum moisture removal rate of 13.1 g/h. The first-stage TEM reached a heating capacity of 68.81 W and a cooling capacity of 26.34 W, while the second stage provided 21.17 W of cooling capacity.

    Koroglu Kaba, Nagihan; Ozturk, Havva

    PURPOSE: This study aimed to determine the effects of laughter yoga and mindfulness on nurses' fatigue, attention levels, and work performance. METHODS: This was a 3-arm, parallel-group, randomized controlled study. Data were collected using the Information Form containing questions about nurses' demographic and professional characteristics, the Chalder Fatigue Scale, the Computerized Sustained Attention Test, and the Individual Work Performance Questionnaire. Nurses completed the tools preintervention, midtest, and postintervention. RESULTS: The study included 101 nurses. At the end of the eight-week interventions, fatigue levels among nurses in the laughter yoga and mindfulness groups were lower compared with the control group (F = 8.805, P < .001). In terms of attention levels, there was no overall difference between the groups; however, in the fourth week only, the hard-level attention scores of the laughter yoga group were higher than those of the control group (F = 5.431, P < .05). Additionally, job performance scores were higher in both intervention groups compared with the control group (F = 9.879, P < .01). Moreover, laughter yoga was more effective than the mindfulness practice in reducing nurses' fatigue and improving their attention levels (P < .05). CONCLUSIONS: Laughter yoga and mindfulness were effective in reducing nurses' fatigue and improving their attention levels and work performance.

    Background The purpose of this study was to examine the impact of Life Kinetik (LK) exercises on balance, agility, jumping performance, proprioception, and cognitive functions in recreationally active preadolescents participating in fencing. Methods The study lasted 8 weeks and included 22 preadolescents recreationally engaged in fencing, aged 11.6 +/- 1.2 years, with an average weight of 49.5 +/- 10.5 kg and an average height of 157.5 +/- 10.0 cm. Preadolescents were randomly assigned to either the LK group or the control group. The experimental group participated in LK exercises twice per week, with each session lasting one hour. Results The results indicate that the changes in Stroop, agility, vertical jump, and proprioception test performance between the pre-test and post-test for the control group are not statistically significant. However, the LK group showed statistically significant improvements in Stroop, agility, and vertical jump performance between the pre-test and post-test (p < 0.001). Conversely, the change in proprioception test performance between the pre-test and post-test for the LK training group was not statistically significant. The changes in star balance test performance between the pre-test and post-test for the control group was not statistically significant. In contrast, the LK group showed a statistically significant improvement in star balance test performance between the pre-test and post-test (p < 0.001). Conclusions These findings indicate that while LK exercises are effective in boosting overall athletic performance, they may not be sufficient for developing specific skills such as proprioception.

    Evaluation of the Effect of Sustainable Drying Techniques and Intensification Technologies on Color Profile of Dehydrated Fruits and Vegetables

    Süfer, Ozge; Koç, Gulsah Caliskan; Öztekin, Sebahat; Karabacak, Azime Ozkan; Su, Dianbin; Wang, Deqing; Eroglu, Salih; Malçok, Senanur Durgut; Uslu, Ulku Hilal; Adal, Samiye

    This research investigates the effects of various drying procedures and intensification technologies on the color profile of dried fruits and vegetables. The primary goal is to identify the most effective techniques for minimizing degradation, which is frequently caused by exposure to heat, oxygen, and longer drying durations, while retaining the original color of these products. Although conventional techniques like sun and hot air drying are often employed, enzymatic and non-enzymatic brownings usually cause a considerable loss of color. New technologies aim to better preserve the original color by cutting down on processing temperature and drying time. The paper also looks at the possibilities of hybrid drying approaches, which combine techniques such as infrared hot air drying and microwave hot air drying. These methods have been demonstrated to be especially successful in preserving color integrity and enhancing drying process effectiveness. The results highlight the vital significance that parameter optimization and drying technique selection play in maintaining the nutritional value and aesthetic appeal of dehydrated fruits and vegetables. This study emphasizes the significance of developing drying technologies to satisfy consumer desires for premium, aesthetically pleasing food goods, because color is a major factor in determining consumer acceptance and perceived product quality. With wider implications for food preservation and the food industry overall, this work helps to develop more effective and efficient drying processes by shedding light on how various drying techniques affect color retention.

    The Role of Women's Entrepreneurship, Unemployment, Global Warming, and Technology in Sustainable Development: Evidence From OECD Countries

    Isik, Cem; Ongan, Serdar; Günlü, Ebru; Aydin, Rahman; Imamoglu, Ilyas Kays

    This study examines the effects of women's entrepreneurship, global warming, technological advancements, and unemployment on the achievement of the sustainable development goals (SDGs) across 38 OECD countries. Using country-specific panel causality methods, the analysis reveals significant asymmetries between developed and developing economies. Women's entrepreneurship (FEM) and technology (TEC) demonstrate stronger positive effects in developing countries such as Mexico, Slovakia, and Costa Rica, supporting SDGs 5 and 9. Global warming (SUR) negatively affects both groups, with notable impacts in Belgium, Mexico, and the UK, emphasizing the urgency of SDG 13. Unemployment (UNM) poses greater threats to sustainable development in emerging economies-particularly in Turkey and Latin American nations-while its influence remains limited in advanced countries. These results underscore the heterogeneous nature of SDG progress and suggest that universal, one-size-fits-all policies may fall short. Instead, national strategies should strengthen gender-inclusive entrepreneurship and innovation, while mitigating climate risks and labor market vulnerabilities. This paper presents a novel, multidimensional econometric framework and offers original insights into how interlinked economic, social, and environmental factors influence sustainability outcomes across diverse national contexts.

    Quantification of Honey Adulteration Using a Planar Microstrip Metamaterial-Motivated Sensor and Software-Defined Radio

    Cem Hasar, Ugur; Hasar, Hafize; Kaya, Yunus; Ozturk, Hamdullah; Korkmaz, Huseyin; Kosunalp, Selahattin; Iliev, Teodor; Tariqul Islam, Mohammad; Nayyeri, Vahid; Mustafa Ramahi, Omar

    This work presents the application of a planar microstrip metamaterial (MM)-motivated sensor in the form of a split-ring resonator (SRR) for the detection and quantification of water adulteration in honey samples. The proposed sensor utilizes inexpensive software-defined radio (SDR) measurements, offering a cost-effective solution. Unlike previous MM sensors employing SRR configuration, our proposed MM-motivated sensor is integrated with a microstrip feedline and an additional vertical bar, enhancing its sensing capability. To enable accurate measurements, a simple calibration procedure based on baseline normalization is implemented, allowing for amplitude-only transmission measurements (|S-21|) using the SDR. A special sample holder was designed to increase the repeatability of measurements. We separately employ two postprocessing techniques, namely, the rolling average (RA) approach and the Savitzky-Golay (SG) filter, to effectively eliminate ripples in the measured |S-21| data obtained from the SDR. For validation and evaluation of the proposed sensor and postprocessing techniques, measurements of flower honey samples with water adulteration levels (delta ) up to 10% (mass-to-mass basis) were also performed using a vector network analyzer (VNA). The resonance frequency of |S21| is utilized as the basis for analysis. We establish a metric function (linear function) that correlates the shift in resonance frequency with delta. It is observed that this function fits to measured resonance frequency values with an R(2 )value greater than 0.96 for both postprocessing techniques with or without the sample holder. By inverting this function, we can predict delta with considerable accuracy for a given resonance frequency by using another linear function. It is observed that percentage variations between predicted and measured delta values are between 1.54% and 6.46% for testing samples with delta = 5% and delta = 7%.

    A Social Approach to Environmental Sustainability: The Nexus Well-Being, Tourism, Digitalization and Renewable Energy in Scandinavian Countries

    Isik, Cem; Ongan, Serdar; Aydin, Buket; Aydin, Rahman; Imamoglu, Ilyas Kays

    This research explores the impact of subjective well-being (SWB) on CO2 emissions in Scandinavian countries based on the need to analyze the effects of social indicators shaping environmental sustainability. The study aims to introduce the Welfare-Based SWB approach to the literature by expanding the classical Environmental Kuznets Curve (EKC) hypothesis with the social welfare dimension. SWB is considered in this study to be a social reflection and indirect measure of economic growth, which is the core determinant in the classical EKC hypothesis. The second-generation cointegration test, the Durbin-Hausman, and AMG long-term forecasting methods were used in this context. According to the empirical findings, SWB and digitalization increase carbon emissions, while tourism revenues and renewable energy consumption reduce emissions. The findings indicate that the classical EKC hypothesis is not confirmed and, similarly, an increase in social welfare (SWB) does not automatically lead to environmental improvement. Therefore, policymakers should develop social policies that will increase environmental sensitivity along with an increase in welfare.

    Characterizations and In Vitro Gut Microbiome Modulatory Effects of Gluco-Oligosaccharides Synthesized by the Acceptor Reactions of Glucansucrase 53

    Bayaman, Rabia Yusra; Alkay, Zuhal; Ispirli, Humeyra; Arioglu-Tuncil, Seda; Dere, Sevda; Can, Hasan; Gonzales, Miguel Angel Alvarez; Sagdic, Osman; Lindemann, Stephen R.; Tuncil, Yunus Emre

    The production of novel oligosaccharides with potential prebiotic effects is of interest to expand the current market and explore the effectiveness of new functional carbohydrate forms. The utilization of glucansucrases is a cost-effective and environmentally friendly biotechnological strategy for producing novel gluco-oligosaccharides through acceptor reactions. In this study, an active glucansucrase (GS53) was used to produce gluco-oligosaccharides via its acceptor reactions with glucose, maltose, and maltotriose, and these oligosaccharides were tested in terms of structure and their gut microbiome modulatory effects. The formations of oligosaccharides were monitored by TLC analysis, and GS53 was active for the three acceptors but not for the other sugars tested. The structural characterization of the gluco-oligosaccharides by 1H NMR analysis revealed the glycosylation of each acceptor with alpha-(1 -> 3) and alpha-(1 -> 6) linkages, whereas LC-MS analysis demonstrated the formations of DP 8, DP 7, and DP 6 oligosaccharides with acceptors maltose, maltotriose, and glucose, respectively. In vitro fecal fermentation analysis, in which microbial short-chain fatty acids (SCFAs) and microbial compositional changes were assessed using gas chromatography and 16S rRNA sequencing, respectively, demonstrated that the gluco-oligosaccharides formed SCFAs-particularly propionate and butyrate-at levels comparable to those observed with inulin, a well-established prebiotic. Additionally, the gluco-oligosaccharides were found to promote the growth of Bifidobacterium adolescentis and Blautia OTUs, which are known to have important physiological functions beneficial to human health. Overall, these results demonstrate that gluco-oligosaccharides synthesized using GS53 through acceptor reactions exhibit prebiotic potentials and could be utilized in the future as dietary supplements as well as in the development of functional foods targeting colonic health.

    This study focuses on groundwater governance in Mediterranean socio-ecological systems, where anthropogenic and climate-related pressures lead to issues such as overexploitation, salinisation, and pollution, particularly in coastal areas. It provides empirical evidence of the practices and processes that foster governance learning and innovation towards adaptive and sustainable groundwater management, drawing on data from a comparative groundwater governance assessment of four case studies,each representing relevant issues within the mosaic of water challenges in the Mediterranean region. This study addresses several knowledge gaps by proposing a framework aligned with a socio-ecological systems approach, allowing for acomprehensive understanding of groundwater governance by consideringinterconnected social, economic, and environmental dimensions. The assessment process integrates diverse data and knowledge sources, and ensures the active participation of local stakeholders. The findings highlight several cross-cutting themes relevant to water governance innovation. These include transdisciplinary collaborations that recognise the multidimensionality of water governance, the role of cultural and social capital as catalysts for community mobilisation, the potential of community participation tools to promote voluntary behavioural changes, and the creation of social learning spaces to co-design scientifically robust and socially acceptable water management options. Furthermore, this study emphasises the integration of the Theory of Change to effectively engage stakeholders in the co-creation of tailored governance solutions, thereby enhancing the potential for sustainable policy outcomes.

    Honey is a rich source of sugar and is one of the indispensable ingredients in infant foods. Thus, it can be subjected to adulteration due to its cost. Measurement techniques such as liquid chromatography and near-infrared spectroscopy, used for detecting any adulteration, are expensive and need to be conducted by highly trained personnel for off-line analysis. Microwave measurements, as a fast, simple, and relatively inexpensive analysis, have recently shown great potential in detecting adulteration within honey samples. Nonetheless, sensor types used in such measurements are conventional. In this study, a reflection-type sensitive microwave sensor terminated by a metal back is proposed for the first time in the literature for the detection and quantification of water percentage ( delta ) level (mass-to-mass basis) within water-adulterated honey samples. When compared with other resonance-based microwave cavity sensors, thanks to its eight strips located at the centers of two closed circular loops, it demonstrates superior frequency selectivity and sensitivity ( S=5.13 %) validated by full-wave 3-D simulations performed by the CST Microwave Studio and equivalent circuit analysis carried out by the Advanced Design System (ADS) software. For example, for ethanol, the proposed sensor gives a frequency shift of more than 1 GHz in the X band. Resonance frequency shift and variation of the reflection coefficient amplitude ( |S11| ) are measured at X band to detect honey samples with up to 8% adulteration level. Three different honey samples (flower honey, highland honey, and thyme honey) were examined to test the performance and applicability of the proposed sensor.
