    Geochemical evaluation of black limestones in the Early Cretaceous platform carbonates of Gümüşhane (NE Turkey): An insight into petroleum source rock potential and palaeoenvironment conditions

    Saydam Eker, Çiğdem; Arı, Uğur Volkan; Alemdağ, Selçuk

    This study assesses the organic matter (OM) content, kerogen type, maturity, depositional environment conditions and sedimentation model of Early Cretaceous (Berriasian–Aptian) black limestones in NE Turkey using geochemical analyses, including Rock-Eval/total organic carbon (TOC), gas chromatography–mass spectrometry, gas chromatography, major and trace elements and stable carbon isotope of OM measurements. The investigated black limestones' TOC, hydrogen index and potential yield values range from 0.07 to 2.91 wt%, 76 to 636 mg HC/g TOC and 0.15 to 11.17 mg HC/g rock, respectively. These results indicate that the examined limestones have variable source rock potential, ranging from low to high. Tmax values, calculated saturated biomarkers and aromatic components suggest that the OM contained in the black limestones varies between thermally immature and mature, consistent with the potential index values. The OM found in the black limestone contained kerogen varying between type I and III. It is a composition of marine and terrigenous OM, as shown by the δ13C isotope values, biomarker components and n-alkane distributions and their parameters. This OM was deposited in a salinity water environment with marine–terrigenous (transitional) surroundings under oxic, suboxic to anoxic and arid–hot climate conditions. These findings provide critical insights for assessing the hydrocarbon potential of carbonate platforms in similar geological settings.

    The effect of psychotherapeutic interventions on pain and quality of life in endometriosis: a systematic review and meta-analysis study

    Özcan, Handan; Çuvadar, Ayşe; Uzun, Sevda

    Aim: This study aimed to determine the effect of psychotherapeutic interventions on pain, quality of life and health profile in women diagnosed with endometriosis. Methods: For this systematic review and meta-analysis study, studies were obtained by searching PubMed, Web of Science, EBSCOhost, Google Scholar, and YÖK Thesis Center databases between August and October 2024 without any year limitation. After the review, 10 studies were included in the study. The data were synthesized by meta-analysis and narrative methods. Results: In this systematic review and meta-analysis, psychotherapeutic interventions for the treatment and management of endometriosis were found to be effective on quality of life (SMD = 0.515, 95% CI = 0.035 to 0.995; Z = 2.104, I2 = 67.523%, p < 0.05), pain (SMD = − 0.454, 95% CI = − 1.600 to − 0.179; Z = − 1.566, I2 = 84.463, p > 0.05), and health profile (SMD = 0.041, 95% CI = − 0.363 to 0.281; Z = − 0.250759, I2 = 56.876%, p > 0.05). In subgroup analyses, it was determined that the types of psychotherapeutic interventions were not effective, but the number of sessions was effective. Conclusion: Psychotherapeutic interventions to reduce symptoms in endometriosis are effective in improving quality of life but not pain and health profile.

    Performance evaluation and optimization of nontraditional inerter-based tuned mass damper for seismic control of multi-story buildings considering SSI effects

    Araz, Onur

    This article presents the optimum design and performance evaluation of a control system that can be an alternative to traditional inerter-based tuned mass damper (TMDI) used in reducing vibrations in a multi-story building under earthquake effects considering soil-structure interaction (SSI). The optimum design of this system, known as NIDVA-C4 in the literature, has been carried out previously considering the randomly excited undamped main system. The key novelty of this work is to demonstrate the applicability of this system to suppress earthquake-induced vibrations in a multi-story building and to deliver more accurate and reliable results by integrating SSI effects into the optimization framework. Due to the difference in location and connection, this system is called N-TMDI in this paper. A case study from the literature featuring a ten-story building is used to implement the design process, assess performance, and conduct comparisons. The optimum parameters of the N-TMDI are obtained using the hybrid PSO-SA algorithm in the frequency domain. Validation using real earthquake records under varying soil conditions confirms the reliability of the proposed optimization framework. The coupled dynamic equations of motion for the structure - N-TMDI, accounting for SSI effects, are formulated and solved in the time domain using the Newmark-β method. An extensive parametric analysis is conducted to evaluate the effectiveness of the N-TMDI in improving the seismic response of the buildings. The results consistently demonstrate the effectiveness of the proposed protection strategy across a wide range of parametric configurations, highlighting its potential as a viable seismic mitigation strategy for a multi-story building.

    Çelik, Romedi; Bilgen, Nüket; Yigin, Akın; Gürler, Şükrü; Bozkaya, Faruk; Kutlu, Furkan; Akkurt, Mustafa Yenal

    The initial phase of the studies focused on the conservation of gene resources involves the phenotypic and genetic characterization of existing breeds. By elucidating the differences at the mitochondrial DNA (mtDNA) level, a particularly suitable source for genetic analyses, it becomes feasible to calculate genetic distances between local breeds, identify potential domestication centers through evolutionary analyses, and construct phylogeny trees depicting kinship relationships between among breeds. Şanlıurfa holds significance in pigeon breeding due to its prolonged history of traditional pigeon breeding, establishing itself as one of the pigeon domestication centers. This study aims to genetically characterize Şebap pigeon breed which is specific to Şanlıurfa province in Türkiye. The mitogenome of the Şebap pigeon was analyzed by next generation sequencing and determined to be 17,232 bp in size, comprising 13 Protein-Coding Genes (PCGs), two Ribosomal RNAs (rRNAs), 22 Transfer RNAs (tRNAs). The overall mitogenome composition includes 29.6% for A, 24.5% for T, 31.2% for C, and 14.7% for G, with a notable A–T richness of 54.1%. Notably, ND6 is encoded on the L strand while the others are encoded on the H strand. Our study has provided a comprehensive examination of whole mitochondrial DNA. Using this information, we have constructed a phylogenetic tree, locating the Şebap pigeon within the rock pigeon lineage.

    Brain Drain-Related Perspectives of Senior Nursing Students in Türkiye: A Qualitative Study; [Türkiye'deki Son Sınıf Hemşirelik Öğrencilerinin Beyin Göçüyle İlgili Görüşleri: Nitel Bir Çalışma]

    Tuncer, Metin; Tuncer, Gülsüm Zekiye

    Objective: This study was aimed at investigating the brain drain-related perspectives of nursing students who wanted to emigrate in depth. Methods: The study has the descriptive qualitative research design. The population of the study comprised 13 senior nursing students studying at the Faculty of Nursing of a university and intending to emigrate abroad. Data were collected through face-to-face individual in-depth interviews. The interviews were audio-recorded after the participants’ permission was obtained. This study adopted a qualitative research design based on inductive content analysis to explore the participants’ perspectives in depth. Results: In this study, three themes emerged from the students' opinions: "Perception of brain drain", "Motivation behind brain drain" and "Challenges". The first theme reflected students’ varied views on migration, including both positive and negative perceptions, a growing social trend towards emigration, and feelings of hopelessness and dissatisfaction with nursing in Türkiye, leading to the formation of personal migration plans. The second theme captured motivations such as the influence of relatives and role models abroad, favourable personal conditions, attractive opportunities overseas, language efforts, and openness to new experiences. The final theme focused on challenges, including push factors like poor working conditions and low wages, barriers such as language and time constraints, and emotional concerns such as loneliness and cultural adjustment. Conclusion: The study showed that nursing students’ intention to emigrate stems from mixed perceptions of brain drain, strong personal and social motivations, and various emotional and structural challenges. Addressing these issues may help mitigate future nurse migration.

    Effect of Foot Anthropometric Measurements on Pain and Functional Disability of Pregnant and Nonpregnant Women

    Koca, Rabia; Sen, Müserref Ebru; Yılmazer, Mehmet

    Background: Weight gain during pregnancy, loosening of the foot ligaments with relaxin hormone release, and anthropometric and biomechanical changes can be seen in the foot with the growing fetus. We sought to determine whether these pregnancy-related changes cause painful musculoskeletal problems by altering the proximal structures of the lower extremities and the structure of the spine. Methods: Both feet of 210 women (half in the third trimester of pregnancy) aged 18 to 40 years with similar demographic characteristics were evaluated by measuring navicular drop, hallux valgus angle, foot width, foot length, and tibiocalcaneal angle. Foot Function Index for foot-ankle, Kujala Patellofemoral Score for knee, Western Ontario and McMaster Universities Osteoarthritis Index for hip, Oswestry Disability Index for waist, and Modified Neck Disability Index for neck were used to determine pain and functional limitation. Results: Pain and functional disability in the waist, hip, knee, and foot-ankle joints; navicular drop; hallux valgus angle; and tibiocalcaneal angle were significantly higher in pregnant women versus the control group (P < .001). Pain and dysfunction in all of the joints increased as navicular drop increased in pregnant and nonpregnant women. In addition, the increase in other anthropometric measurements in both groups was determined to caused pain and functional disability in most of the women, especially in foot-ankle joints. However, the cause of joint pain and functional deficiencies was unrelated to pregnancy. Conclusions: Foot deformities and proximal region complaints were significantly higher in pregnant women, and foot deformities caused more foot-ankle pain and disability in both groups. No difference was observed in pregnant women versus the control group.

    A Video-Based Mobile Palmprint Dataset and an Illumination-Robust Deep Learning Architecture for Unconstrained Environments

    Koşmaz Sünnetci, Betül; Bingöl, Özkan; Gedikli, Eyüp; Ekinci, Murat; Doğan, Ramazan Özgür; Türk, Salih; Güngör, Nihan

    Featured Application: The proposed framework facilitates secure and user-friendly biometric authentication on mobile platforms, particularly in mobile payment and access control scenarios, under unconstrained conditions. The widespread adoption of mobile devices has made secure and user-friendly biometric authentication critical. However, widely used modalities such as fingerprint and facial recognition show limited robustness under uncontrolled illumination and on heterogeneous devices. In contrast, palmprint recognition offers strong potential because of its rich textural patterns and high discriminative power. This study addresses the limitations of laboratory-based datasets that fail to capture real-world challenges. We introduce MPW-180, a novel dataset comprising videos of 180 participants recorded on their own smartphones in everyday environments. By systematically incorporating diverse illumination conditions (with and without flash) and natural free-hand movements, MPW-180 is the first dataset to adopt a bring-your-own-device paradigm, providing a realistic benchmark for evaluating generalization in mobile biometric models. In addition, we propose PalmWildNet, an SE-block-enhanced deep learning architecture trained with Triplet Loss and a cross-illumination sampling strategy. The experimental results show that conventional methods suffer over 50% performance degradation under cross-illumination conditions. In contrast, our method reduces the Equal Error Rate to 1–2% while maintaining an accuracy above 97%. These findings demonstrate that the proposed framework not only tolerates illumination variability but also learns robust illumination-invariant representations, making it well-suited for mobile biometric authentication.

    Development and Validation of a Scale Based on Protection Motivation Theory to Investigate Factors Affecting Earthquake Preparedness Behaviors

    Yücel, Hasan; Cengiz, Sevil

    Given Türkiye’s high seismic risk, earthquake preparedness is vital. This study explored factors affecting earthquake preparedness behaviors among residents in high-risk areas. The factors affecting earthquake preparedness behaviors Scale based on protection motivation theory was developed, and its validity was tested. Scale development consists of a pilot and main application process. The pilot application was carried out with 50 participants, and the main application was carried out with 804 participants. The sample consisted of 804 participants who were divided into two groups for exploratory and confirmatory factor analysis. The sample was selected from 11 neighborhoods using the cluster sampling method. IBM SPSS 25 was used for exploratory factor analysis, while AMOS 24.0 was employed for confirmatory factor analysis. The final version of the scale consists of 24 items across four dimensions, with a Cronbach’s alpha of 0.883, exceeding the acceptable threshold of 0.7 for each dimension. The Kaiser–Meyer–Olkin value is 0.898, and Bartlett’s test of sphericity is significant, with the total variance explained being 51%. Confirmatory factor analysis results indicate a good fit for both the measurement and structural models (χ2/df = 1.779; RMSEA = 0.44; CFI = 0.96; NFI = 0.91; TLI = 0.95; p<0.001). Structural equation modeling showed that, among the constructs of protection motivation theory, perceived efficacy (β = 0.690) is the most important factor affecting earthquake preparedness behaviors. The results show that the scale is a valid and reliable tool to determine the factors affecting earthquake preparedness behaviors in Turkish society.

    A new mathematical model for cellular manufacturing system with productivity consideration

    Atmaca, Hatice Ediz; Erdogan Akbulut, Hatice; Aktas, Esra

    In today’s environment of escalating competition, companies are adapting their management and production strategies, and product diversity is rapidly increasing. Companies require cellular manufacturing systems to produce products with high diversity in a short amount of time, ensuring the desired quality and meeting customer expectations. Cellular manufacturing systems, which have a more flexible structure compared to traditional production systems, are a good and effective solution for man-agers. Cellular manufacturing is an approach that aims to produce products with varying diversity in the shortest possible time and at the lowest cost, targeting an increase in efficiency. In this study, a cell manufacturing system proposal is made and cell formation is carried out to increase efficiency and effectiveness in a company that manufactures industrial refrigeration cabinets. A productivity-based 0-1 integer mathematical programming model is prepared that facilitates the simultaneous grouping of part and machine families in cell formation. In addition to the intracellular and intercellular transportation costs found in productivity-based models in the literature, labor costs, maintenance costs, the depreciation costs of the machines used in the cells, and the waiting costs of the machines are also added to the prepared model. The model is solved with the help of the GAMS 23.5.1 software package, creating part families and machine groups. Group efficiency values are measured, and the current and proposed situations are compared.

    Response of tibia bone morphology, biomechanics and minerals to Organic Hawthorn (Crataegus tanacetifolia) Fruit Vinegar application in broiler chickens exposed to cyclic heat stress

    Kaya, Hacer

    This study aimed to determine the effects of adding different doses of organic hawthorn fruit vinegar (HFV) to the drinking water of male broilers (Ross 308) reared under cyclic heat stress (CHS) on tibia bone morphology, biomechanics, and minerals. Broilers were distributed into six groups based on a 2 × 3 factorial design, testing two ambient temperatures (24 and 35°C CHS for 8 h/day starting from day 21) and three HFV levels (0, 2, and 4 ml/L). Cyclic heat stress had no effect on the morphological and biomechanical properties of the tibia bone, except for a decrease in cortex thickness (P < 0.05). However, CHS significantly decreased the bone Ca, P, Mg, Cu, Zn, Mn, and K levels, while increasing the Fe levels (P < 0.01). The addition of 2 and 4 ml/L HFV had no effect on the morphological and biomechanical properties of the tibia bone (P > 0.05), except for an increase in bone diameter with 2 ml/L HFV (P < 0.05). HFV additions were not sufficient to increase the Ca level decreased by CHS, and the tibia bone Ca level of birds under CHS decreased further with HFV additions (P < 0.01). Conversely, 2 ml/L HFV increased Mg levels, and both 2 and 4 ml/L HFV increased Cu, Fe, Zn, and Mn levels, whereas P levels decreased (P < 0.01). K level decreased with 2 ml/L HFV and increased with 4 ml/L HFV supplementation. In conclusion, HFV supplementation has positive effects on bone mineralization in broilers exposed to HS and can be used up to 4 ml/L to mitigate the negative effects of heat stress.

    Depth Estimation Based Automatic Pose Correction in Hand Images

    Sünnetci Koşmaz, Betül; Bingöl, Özkan; Gedikli, Eyüp; Ekinci, Murat

    In palm biometric recognition systems, the hand being at different angles and positions relative to the camera presents a critical challenge in terms of accuracy and reliability. Especially in images captured in free environments, hand misalignment can negatively affect recognition performance by making it difficult to extract biometric attributes. Perspective distortions due to camera position change the geometric structure of the hand, compromising biometric data integrity. While 3D imaging systems can offer successful solutions for pose normalization, performing a similar transformation for 2D images poses a major technical challenge. In this study, depth estimation supported plane fitting is used to remove perspective distortions in 2D images and pose normalization of the hand is obtained. The proposed method uses the information obtained from depth estimation to realign the hand image as if it were standing directly in front of the camera, improving geometric consistency. This will make the extraction of biometric features more reliable and contribute to improving the accuracy of palm recognition systems.

    The Effect of Boric Acid on Oxidative Stress, Inflammation, and Apoptosis in Embryonic and Fetal Tissues Damage Caused by Consumption of High-Fructose Corn Syrup in Pregnant Rats

    Başeğmez, Mehmet; Yüksel, Duygu

    This study aimed to determine the protective role of boric acid in a pregnant rat model of high fructose corn syrup consumption. Consumption of high fructose corn syrup has been associated with adverse health outcomes in humans and animals. Twenty-eight healthy female Wistar albino rats (250–300 g weight and 16–24 weeks old) were randomly distributed into four equal groups (n = 7): Control, Boric acid (BA), High Fructose Corn Syrup (HFCS), HFCS + BA. Boric acid (20 mg/kg) was administered to pregnant rats via oral gavage every day during pregnancy. The prepared 30% HFCS (F30) solution (24% fructose, 28% dextrose) was added to the drinking water throughout pregnancy. At the end of pregnancy (day 19), blood, placenta, uterus, and fetuses were collected from rats. The results indicated that HFCS increases oxidative stress by increasing the level of MDA and decreasing GSH, SOD, and CAT activity in the blood of maternal. However, BA administration significantly decreased MDA levels and increased GSH levels, SOD, and CAT activity (p < 0.05). In addition, HFCS consumption significantly increased plasma TNF-α, IL-6, and leptin levels compared to control, BA, and HFCS + BA groups (p < 0.05). However, BA administration significantly decreased plasma TNF-α, IL-6, and leptin levels (p < 0.05). Furthermore, BA (20 mg/kg) significantly decreased HFCS-induced histopathological and immunohistochemical alterations in the placenta, uterus, and fetal tissue. In conclusion, BA may prevent HFCS toxicity in maternal and fetal tissues, as it regulates oxidative imbalance in pregnant rat and alleviates histopathological and immunohistochemical changes. The findings indicate a need for further studies to assess the potential of boron in preventing or mitigating the effects of HFCS during pregnancy.

    Investigation of Tensile and Fatigue Behavior of Cr/CrN/TiCrN/TiCrCN Multilayer Films Coated on AA6063 and AZ91 Alloys by Closed-Field Unbalanced Magnetron Sputtering Process

    Yeşildal, Ruhi; Sezer, Sadberk; Karabudak, Filiz

    Despite the widespread use of Mg and Al alloys among light metals in the automobile and aviation industries, they have low tensile and fatigue strength. Therefore, in the present work, AZ91 Mg and AA6063 Al alloys were coated with a multilayer transition metal nitride film (Cr/CrN/TiCrN/TiCrCN) to increase fatigue and tensile strength. Films with Cr/CrN/TiCrN/TiCrCN microstructure architecture were synthesized on the surfaces of AZ91 Mg and AA6063 Al alloys using the CFUBMS (closed-field unbalanced magnetron sputtering) system, one of the PVD (physical vapor deposition) techniques. Films’ structural properties were analyzed by XRD, SEM, and EDAX, whereas mechanical properties were investigated using tensile and rotary bending fatigue testing machines. According to the SEM examination, the Cr, CrN, TiCrN, and TiCrCN multilayer nitride films on the two alloys have a columnar and dense microstructure. The XRD analysis detected Cr (211), CrN (111) and (200), TiN (111), (200) and (222), and TiCN (200) and (311) diffraction peaks. The Cr/CrN/TiCrN/TiCrCN multilayer coating increased the fatigue limit value of AZ91 by 11.22% from 70.26 MPa to 78.15 MPa. The fatigue limit value of AA6063 decreased by 9.79% from 79.71 MPa to 71.9 MPa. After coating, the tensile strength value of AZ91 increased from 137.89 MPa to 139.65 MPa, while the tensile strength of AA6063 decreased from 129.35 MPa to 118.16 MPa.

    Towards precision dentistry through artificial intelligence and blockchain-based digital Twins: Investigating challenges and solution strategies

    Erol, Ismail; Peker, Iskender; Medeni, Ihsan Tolga; Yuce, Fatma

    The integration of artificial intelligence (AI), blockchain, and digital twins (DT) in dentistry is essential to meet evolving patient expectations and global healthcare challenges. However, realizing their full potential requires addressing significant adoption barriers. While conceptual studies have explored challenges to implementing AI, blockchain, and DT in dentistry, no prior research has systematically analyzed the interrelationships among these obstacles using a structured decision framework. This study employs pentagonal fuzzy (PF) DEMATEL to investigate the connections among challenges to effectively implementing AI and blockchain-based DT in dentistry. Expert opinions highlight ethical considerations and bias and fairness in AI-based DT as the most critical causal challenges. We propose an AI and blockchain-based DT architecture that enables human doctors to leverage DT-based decision support, while AI-driven systems execute high-precision procedures with blockchain-verified workflows. This framework enhances treatment accuracy and personalization in dentistry and offers a scalable model for addressing societal concerns, such as privacy, fairness, and labor dynamics, in technology-driven ecosystems. A pilot study framework is proposed to validate diagnostic accuracy, data security, and treatment customization. Accompanied by stakeholder guidelines, this research bridges dentistry with broader discussions on technology's societal impact, emphasizing the need for interdisciplinary strategies to ensure equitable and trustworthy innovation.

    Validity and reliability of the Turkish version of the chrono-med diet score (CMDS) for adult participants

    Koçak, Tevfik; Kocyigit, Emine; Ağagündüz, Duygu

    Background: This study aimed to examine the validity and reliability of the Chrono-Med Diet Score (CMDS) to assess adherence to the Mediterranean diet in Turkish adults. Methods: The methodological research conducted in Gümüşhane and Ordu from January to June 2024, including 592 individuals (62.3% women, 37.7% men, and the mean age 43.4 ± 10.6 years). Data were collected through face‒to‒face interview that contained socio-demographic characteristics, the CMDS, the Mediterranean Diet Adherence Screener (MEDAS), and 24-h dietary recall. Internal consistency reliability was assessed using Cronbach’s alpha coefficient, while repeatability was examined using the test–retest method. Construct validity was assessed by the MEDAS, and components of the adapted CMDS obtained from the 24-h dietary recall were analyzed using confirmatory factor analysis. The content validity was assessed by the Paired samples t-test and Wilcoxon test. The Bland–Altman test with 95% limits of agreement was used to evaluate the agreement between sum of CMDS. The results were statistically evaluated at a p < 0.05 significance level. Results: The content validity index of CMDS was 0.87. The overall Turkish version of CMDS had acceptable internal consistency (Cronbach’s α = 0.853), thus indicating that the score was reliable. The Paired samples t test coefficients between each item and the overall questionnaire ranged from 0.234 to 1.000. A higher intake of olive oil and fish obtained from a 24-h dietary recall was associated with a higher CMDS quartile (p < 0.05). The MEDAS score was correlated with a higher CMDS quartile (p < 0.001). A moderate positive correlation was determined between total CMDS and MEDAS (r = 0.467; p < 0.001). Conclusions: Our assessments of the CMDS, consisting of 13 items, in Türkiye demonstrate that it is a viable and reliable instrument to measure adherence to the Mediterranean diet for the adult population. The CMDS is more accurate than other Mediterranean diet scores as it questions about the amount of physical activity and grain products, which helps determine each participant’s eating patterns and general health.

    Snow-covered land surfaces can be easily mapped using remote sensing technologies. Accurate estimation of snow cover on the land surface allows for the construction of water resource management today. Using Landsat TM/ETM + satellite images, this study tried to assess how much snowfall covered the soil in Trabzon, Gümüşhane, and Bayburt provinces between 1999 and 2023. Satellite images were classified into three categories using the ERDAS 9.1 TM software. These classes are classified as snow-covered surfaces, other places, and data loss (cloud-shadow). When performing image analysis, it was important to verify that the cloudiness rate in the images was less than 15%. Images with cloudiness rates of more than 15% were not used. Seasonal and annual trend analysis of snow-covered areas (SCA) over three distinct regions (Trabzon, Gümüşhane, and Bayburt) were examined using the Mann-Kendall test. When three distinct study regions were examined together, Bayburt had the highest SCA rate, followed by Gümüşhane and Trabzon. In all three fields, the highest SCA was recorded in 2000, while the lowest SCA was recorded in 2017. The trends noticed that SCA on both annual and seasonal scales did not reach the statistical significance level of 0.05. Although snowfall in Trabzon, Gümüşhane, and Bayburt was beneficial in the autumn and spring seasons, no statistically significant association was found. The research concluded that the existing data are inadequate to make any statements on the impact of global warming in the area. However, the study figured out that satellite data may be effectively used to identify snowy places as a result of the study. Comparable investigations need to be undertaken in regions with varying climates, utilizing diverse remote sensing data and classification methodologies.
