Acoustic-Based Fault Diagnosis of Electric Motors Using Mel Spectrograms and Convolutional Neural Networks
(Nature Portfolio, 2025) Uzel, Hasan; Ozupak, Yildirim; Alpsalaz, Feyyaz; Aslan, Emrah; Zaitsev, Ievgen
This study presents a comprehensive deep learning framework for diagnosing acoustic faults in electric motors. The framework uses Mel spectrograms and a lightweight convolutional neural network (CNN). The method classifies three motor states, engine_good, engine_broken, and engine_heavyload, based on audio recordings from the IDMT-ISA-ELECTRIC-ENGINE dataset. To prevent data leakage and ensure a robust evaluation, the study employed file-level splitting, session separation, 5-fold cross-validation, and repeated trials. The raw audio signals were transformed into Mel spectrograms and processed through a CNN architecture that integrates convolutional, pooling, normalization, and dropout layers. Quantitative metrics, including THD, spectral entropy, and SNR, further characterize the acoustic distinctions between motor states. The proposed model achieved a test accuracy of 99.7%, outperforming or matching state-of-the-art approaches, such as ResNet-18, CRNN, and Transformer classifiers, as well as traditional MFCC-based baselines. Noise robustness and sensitivity analyses demonstrated stable performance under varying SNR conditions and preprocessing settings. Feature-importance maps revealed that low-frequency regions (0-40 Mel bins) were key discriminative components linked to physical fault mechanisms. Computational evaluation confirmed the model's real-time feasibility on embedded hardware with low latency and a modest parameter count. Though primarily validated on one motor type, external-domain testing revealed strong adaptability. Future work may incorporate transfer learning or multimodal fusion. Overall, the proposed framework provides a highly accurate, interpretable, and efficient solution for real-time motor fault diagnosis and predictive maintenance in industrial environments.

Bloodless Executions in the Seljukid State Tradition: The Procedures and Principles of Choking With Bowstring and Drawing Iron Rod To Eyes
(Selcuk Univ, Fac Letters, 2025) Selcukoglu, Ahmet
In medieval sources, two popular liquidation methods are mentioned that were frequently applied by Turkish nations, especially in the context of sovereignty conflicts: Strangling with a bowstring and pulling a hot iron rod to the eyes. In the steppe law, the red lines regarding not shedding the blood of the dynasty members brought to the forefront alternative methods for dealing with the defeated opponent, and strangulation was used as a functional execution method because it achieved the goal without shedding blood. Although the strangling process is carried out with different tools and techniques, bows, one of the most important instruments of Turkish daily life, are the most frequently used tools for this purpose. Among the Turkish states, the Seljuks were one of the states that most frequently used the punishment of strangulation with a bowstring and carried this ancient steppe custom to distant areas of domination. However, after the Seljuks' interaction with Iran, Anatolia and the Islamic world, a different method of elimination began to become more popular and was frequently used in struggles for dominance. In this execution method, which is described in the sources as drawing an iron rod into the eyes, the aim was to heat a long stick called "mil" in the fire and hold it to the eyes from a certain distance, thus causing the victim to lose his ability to see. This article aims to examine the practices of strangulation with a bowstring and drawing a hot iron rod to the eyes, which are frequently mentioned as a type of bloodless execution in the sources, within the context of logic, method and technique within the framework of the Turkish steppe law and sovereignty concept using examples from the Seljuk period.
Comparative Resistance of Barley and Wheat Germplasm to Common Root Rot Caused by Bipolaris Sorokiniana
(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2026) Alkan, Mehtap; Korkulu, Serife Gul; Turkkan, Muharrem; Dervis, Sibel; Yuksel, Soner; Dababat, Abdelfattah A.; Ozer, Goksel
This study evaluated the resistance of 54 wheat and 14 barley cultivars in Bolu, and 6 wheat cultivars and 89 barley lines in Eski & scedil;ehir, to common root rot caused by Bipolaris sorokiniana under controlled conditions. Location-specific B. sorokiniana isolates (wheat-derived in Bolu, barley-derived in Eski & scedil;ehir) were employed for evaluation. In Bolu, wheat cultivars demonstrated tolerance with variable disease severity, while barley cultivars showed moderate susceptibility with significantly greater disease severity than wheat. Conversely, wheat cultivars in Eski & scedil;ehir exhibited complete resistance with no symptoms, whereas barley lines displayed responses ranging from complete resistance to high susceptibility. Eight wheat cultivars and two barley lines achieved complete resistance across both locations. Neither growth habit (spring vs. winter) in wheat nor row-type (two-row vs. six-row) in barley significantly influenced disease severity. The consistent difference in disease severity between barley and wheat, with barley exhibiting greater susceptibility, highlights the importance of targeted breeding efforts for each crop. Field evaluations are crucial to validate the findings under natural conditions and refine disease management strategies.
Performing Womanhood in Schools: A Feminist Phenomenological Investigation of Female Teachers' Psycho-Social Health Experiences and Implications for Educational Leadership in Turkey
(Frontiers Media SA, 2025) Is, Engin
This study employs a feminist phenomenological approach to examine the psycho-social health experiences of female teachers in Turkey as they navigate the demands of professional and domestic life. Drawing on semi-structured interviews with 28 teachers across different school levels, the study explores how participants internalize, negotiate, and perform socially constructed gender roles in both public (school) and private (home) spheres. Thematic analysis identified key challenges, including role conflict, emotional labor, burnout, and guilt, all shaped by dominant gender norms and structural inequalities. Grounded in feminist theories-gender performativity (Butler), hegemonic masculinity (Connell), and intersectionality (Crenshaw)-the study demonstrates the embodied impacts of gendered oppression on women's mental health. Participants' coping strategies, including resilience and social support, are interpreted as both survival mechanisms and subtle forms of resistance. The findings underscore the urgent need for gender-sensitive institutional policies, flexible working arrangements, and psychosocial support programs to promote teachers' well-being and equality in the education system.
The Emotions Experienced by Women Undergoing Mastectomy Over the Course of the Disease and Treatment: A Qualitative Study
(Springer, 2025) Soylemez, Neslihan; Tanriverdi, Seher; Cengiz, Zeliha; Can, Hilal
PurposeObtaining firsthand insight into breast cancer facilitates a detailed understanding of women with breast cancer' emotional experiences, thereby promotes holistic cancer care. This study aimed to identify the emotions experienced by women undergoing mastectomy during the disease and treatment process.MethodsThis qualitative study, based on a descriptive phenomenological design, was conducted using semi-structured interviews to explore the emotions of women who had undergone mastectomy during the diagnosis and treatment stages. Twenty-nine breast cancer women with breast cancer aged 27-68 who had undergone mastectomy participated in the study, which was carried out in the general surgery clinic of a university hospital. The data obtained from the interviews were subjected to thematic analysis.ResultsIt was found that women undergoing mastectomy experience a wide range of emotions at all stages of breast cancer and develop corresponding coping strategies. Five themes emerged from the analysis: emotions related to diagnosis, emotions related to treatment, future-oriented emotions, coping strategies, and family and social relationships. Unlike the findings reported in the literature, this study revealed that women often expressed reactions such as "wanting to die" or "not feeling anything" during the diagnosis process. In terms of family relationships, diverse factors such as divorce, spousal psychological violence, spousal support, and physical violence were noted.ConclusionsHaving breast cancer triggers profound emotional fluctuations in women, such as fear, uncertainty, burnout, and disturbances in self-perception. While hope and optimism for the future are fueled by positive emotions such as social support and a desire to see children happy, negative experiences such as cancer stigma and psychological violence increase the emotional burden. Supportive care teams are recommended to enhance psychosocial support services, promote the emotional well-being of women after mastectomy, strengthen family and social participation, develop individualized care plans, and implement holistic approaches through team-based care.
Relationship Between Cryptocurrency Trading, Hopelessness, and Financial Well-Being: A Cross-Sectional Study Among Physicians
(Int Scientific Information, Inc, 2025) Donmezdil, Suleyman; Uyar, Betul
Background: Cryptocurrencies trade continuously on highly volatile markets and can elicit emotionally driven, gambling-like behaviors. Physicians experience high occupational stress and burnout, potentially predisposing them to risky financial activities. We examined whether hopelessness and perceived financial well-being are associated with problematic cryptocurrency trading among physicians. Material/Methods: In a cross-sectional online survey, 300 licensed physicians from Diyarbak & imath;r, Turkey, completed the Beck Hopelessness Scale (BHS; score range, 0-20), Financial Well-Being Scale (FWBS; 0-100), and Problematic Cryptocurrency Trading Scale (PCTS; 16-80). Group differences were evaluated with t tests and chi-square tests, and multivariable linear regression models estimated PCTS predictors. Results: Participants' mean age was 39.8 +/- 7.2 years; 70% were male; mean practice duration was 14.1 +/- 6.9 years. Male physicians had higher PCTS scores than female physicians (33.0 +/- 6.8 vs 29.8 +/- 5.9; P=0.03); BHS and FWBS scores did not differ by sex. In regression models, older age ((3=0.32, P=0.04) and male sex ((3=1.45, P=0.02) predicted higher PCTS scores. Hopelessness was positively associated with PCTS ((3=0.80, P=0.001), whereas financial well-being showed a trend toward significance ((3=-0.03, P=0.067). The demographics-only model explained approximately 8% of PCTS variance; the psychosocial model R2=0.35 (P<0.001). Conclusions: Among physicians, male sex, older age, and higher hopelessness are independently associated with problematic cryptocurrency trading, while perceived financial well-being is not clearly protective. Targeted institutional interventions (financial literacy and stress-management programs) may mitigate compulsive trading and support physician well-being.

Assessment of Food Insecurity, Diet Quality, and Mental Health Status Among Syrian Refugee Mothers with Young Children
(MDPI, 2025) Coskunsu, Sedat; Yilmaz, Muge
Background: Although T & uuml;rkiye hosts the largest population of Syrian refugees in the world, research on the vulnerability factors contributing to food insecurity among Syrian refugee mothers remains scarce. The aim of this study was to investigate the relationships between maternal food insecurity, diet quality, and mental health outcomes among Syrian refugee mothers with young children living in T & uuml;rkiye. Methods: This cross-sectional study involved 285 Syrian mothers living in T & uuml;rkiye with children under five years of age. Maternal food insecurity was assessed via the Food Insecurity Experience Scale (FIES), diet quality was evaluated via the Healthy Eating Index-2020 (HEI-2020), and the Patient Health Questionnaire-9 (PHQ-9) was used to evaluate mental health conditions. Data were collected through face-to-face surveys conducted by two native Arabic translators, and the analyses included sociodemographic characteristics, anthropometric measurements, diet quality, food insecurity status, and mental health status. Results: The prevalence of moderate/severe food insecurity and poor diet quality among refugee mothers amounted to 30% and 59.3%, respectively. Mothers experiencing food insecurity presented significantly lower levels of mental health and diet quality (p < 0.05). A one-unit increase in the food insecurity score was associated with an increase of 1.031 units in the total Patient Health Questionnaire-9 (PHQ-9) score. The model demonstrated that food insecurity accounted for 30.2% of the variance in PHQ scores (R-2 = 0.302). Low income, lack of institutional aid, short length of stay, and number of children significantly increase the likelihood of poor dietary quality among refugee mothers. Conclusions: Food insecurity was found to be a widespread problem for mothers who are refugees from Syria. It was significantly associated with poorer nutritional quality and mental health issues in mothers. These findings suggest the need for expanding social support programs, implementing effective public health interventions for food security, and securing an overall improvement of maternal health.
Syrian Civil War and Assessment of Tuberculosis Among Syrian Refugees and Local Citizens in Mardin
(Frontiers Media SA, 2025) Cil, Baris; Kabak, Mehmet; Bodur, Mehmet Sinan; Sanmak, Erkan; Gunes, Guldan; Alakas, Yusuf; Oktay, Hamza
Background: We compared tuberculosis (TB) characteristics and outcomes between Syrian refugees and local citizens in Mardin, Turkey (2016-2023), a border province with substantial population mobility. Methods: Retrospective, registry-based cross-sectional analysis of 491 patients (locals n = 456; refugees n = 35). Descriptive comparisons used chi(2)/Fisher (categorical) and Mann-Whitney U (age). Annual incidence per 100,000 used mid-year denominators (locals: ABPRS/NVI; refugees: DGMM/PMM and UNHCR). For outcomes with significant crude differences (treatment success, BCG scar, transferred-out), age- and sex-adjusted bias-reduced (Firth) logistic regression was applied; p-values from penalized likelihood-ratio (PLR) tests. Results: BCG-scar positivity was lower in refugees than locals (62.9% vs. 93.2%, p < 0.001). Microbiological confirmation remained below WHO targets in both groups. Crude treatment success was lower in refugees (68.6%) than locals (90.4%, p = 0.03), while transferred-out was higher (25.7% vs. 5.3%, p = 0.001). In adjusted Firth models including all cases, refugee status was associated with lower odds of success (aOR 0.224, 95% CI 0.103-0.488; PLR p < 0.001); after excluding transferred-out cases the association attenuated and was not significant (aOR 0.562, 95% CI 0.121-2.605; PLR p = 0.42). In pulmonary-only analyses, the association persisted (aOR 0.216, 95% CI 0.083-0.567; PLR p = 0.002). Refugee incidence dipped in 2020-2021 and rebounded in 2022-2023. Conclusion: Differences likely reflect operational barriers-especially transfers disrupting continuity-rather than intrinsic factors. Refugee-inclusive TB services with robust inter-provincial transfer tracking, patient navigation, and expanded bacteriological testing (notably for extrapulmonary disease) should be prioritized. Given the small refugee subgroup and denominator uncertainties, findings are hypothesis-generating.
Self-Control as a Key Mediator and Moderator of the Relationship Between Psychological Distress and Food Addiction in a Large Community Sample of Adults
(Academic Press Ltd- Elsevier Science Ltd, 2026) Ceylan, Jiyan Aslan; Korkmaz, Aziz; Hatipoglu, Abdulkerim; Akcali, Caglar; Coskunsu, Sedat
Objective: This study investigated the extent to which psychological distress (depression, anxiety, and stress) predicts food addiction (FA) symptoms and examined whether self-control operates as both a mediator and a moderator in these associations. Method: A total of 4234 adults (40.7 % male) participated in a large-scale, community-based, cross-sectional survey conducted in T & uuml;rkiye. FA symptoms were measured via the Yale Food Addiction Scale (YFAS), self-control was assessed via the Brief Self-Control Scale (BSCS), and psychological distress was evaluated via the Depression Anxiety Stress Scales (DASS-21). Statistical analyses were conducted in SPSS, with significance defined at p < 0.05. Results: Overall, 35.1 % of the participants met the criteria for FA, with no significant sex difference (p = 0.19). Logistic regression analyses revealed that greater anxiety (OR = 1.078, p < 0.01) and stress (OR = 1.109, p < 0.01) were significant predictors of increased risk for FA, whereas greater self-control emerged as a protective factor (OR = 0.952, p < 0.01). Mediation analyses confirmed that self-control partially accounted for the effects of psychological distress on FA symptoms, with significant indirect effects observed for stress (beta = 0.025), anxiety (beta = 0.029), and depression (beta = 0.032). Moderation analysis revealed that self-control attenuated the effect of depression on FA symptoms (interaction term: B = 0.002, p < 0.01), although no moderating effects were found for anxiety or stress. Conclusions: This study highlights self-control as both a mechanism through which psychological distress contributes to food addiction and a protective factor that reduces its impact. Enhancing self-control may help mitigate addiction-related eating behaviors.
A New Green Corrosion Inhibitor for Mild Steel in 1 M HCl Using Erodium Cicutarium (L.) Leaf Extract: Insights From Both Theoretical and Experimental Methods
(Elsevier, 2026) Ergel, Busra; Yildiz, Resit; Arslanhan, Selim; Baran, Mehmet Firat
Considering the economic and environmental conditions, corrosion appears to be a significant handicap. In this study, anti-corrosion performance of Erodium cicutarium (L.) (EC) is explored in a 1.0 M HCl using potentiaodynamic polarization (PDP), electrochemical impedance (EIS) and linear polarization resistance (LPR) spectroscopies along with morphological, structural and quantum chemical methods. FT-IR and LC-ESI-MS/MS reveal the chlorogenic acid, gentisic acid, protocatechuic acid, vanillin and salicylic acid, containing-C=O, C=C, C-H, C-H, -OH, and aromatic ring. PDP, EIS and LPR showed that at the highest concentration of the EC extract (1000 ppm), the polarization resistance and corrosion current density are measured as 974 Omega cm2 and 246 mu A cm-2, while the inhibition efficiency was found to be 98 %. Inhibition efficiencies decreased with increasing temperature and exposure times due to desorption of adsorbed inhibitor molecules from the surface. But, a notable increase in the Ea value (67.2 kJ mol-1) is observed, thereby hindering the corrosion process. While adsorption behavior is in accordance with the Langmuir isotherm, the Delta G degrees ads (-27.34 kJ mol-1) value indicates both physical and chemical adsorptions. To better understand the inhibitory mechanism, zero charge potential is determined, and quantum chemical calculations of the EC extract's components are performed.
Role of Machine Learning Segmentation Method Based on CT Images in Preoperative Staging of Oral Cavity Cancer
(Springer, 2025) Can, Sermin; Succo, Giovanni; Coskun, Cengiz; Korkmaz, Mehmet Hakan; Akdag, Mehmet
ObjectiveThe article aims to demonstrate, using oral cavity SCC as an example, that machine learning can accurately predict the T and N staging of OSCC, using the conventional radiologist/ surgeon interpretation of the scan as the reference standard.Materials and methodsTwo datasets for tumor mass and nodal metastasis were used in this study. Each of the datasets consists of 179 Contrast-enhanced Computed Tomography images. A customized U-Net deep learning architecture was employed for the segmentation of tumor masses and nodal metastases. Comprehensive maps of the tumor mass and metastatic lymph nodes were generated. Following this mapping process, the dimensions of the identified lesions were measured and classified according to the Tumor and Lymph Node Metastasis classification system. The resulting classifications were then compared with those established by a radiologist to assess accuracy.ResultsThe performance metrics for tumor mass and metastasis segmentation were as follows: binary accuracy value of 98.81% and 99.58%, respectively. The accuracy values were 75.00% for tumor grade classification and 97.22% for nodal status classification.ConclusionWe emphasize that machine learning-based segmentation methods effectively predict tumor mapping and staging in oral cavity tumors, demonstrating correlation with surgeons/radiologists' assessments. As such, this model can be a diagnostic tool that supports clinicians in making informed therapeutic decisions. We foresee that, with the continuous evolution of technology, the segmentation model employed in our study will undergo significant advancements, ultimately facilitating three-dimensional tumor mapping in the near future.
Impact of Iron Deficiency Anemia on Electrocardiographic Markers in Pediatric Patients
(Wiley, 2025) Orhan, Ozhan; Aktan, Adem
Background Iron deficiency anemia (IDA) is a condition in which healthy red blood cells are inadequately produced in children and, if left untreated, can lead to serious health problems. The impact of IDA on electrocardiographic (ECG) markers in children has not been sufficiently investigated, emphasizing the need for more comprehensive studies in this regard.Methods This study, conducted in our clinic, includes 75 children diagnosed with anemia and a control group of 77 healthy children. ECG analysis was employed to assess depolarization and repolarization parameters, including measurements such as QT interval, Tp-e interval (Tp-e), cardiac electrophysiological balance index (iCEB), and frontal QRS-T angle.Results The ECG parameters of children with IDA and ferritin levels below 15 ng/mL were contrasted with those of healthy children having ferritin levels exceeding 25 ng/mL. The anemic group exhibited significantly higher values for QT interval, corrected QT (QTc), Tp-e, P-wave dispersion (PWd), QT dispersion (QTd), corrected QTd, Tp-e dispersion, iCEB, and corrected iCEB compared to the control group. In the Pearson correlation analysis, a weak and negative correlation was found between ferritin levels and QT dispersion (p = 0.002) and QTc dispersion (p = 0.039). No significant relationship was detected between other parameters. These observations imply that IDA in children might induce alterations in depolarization and repolarization, potentially elevating the susceptibility to arrhythmias.Conclusions Our study demonstrated significant alterations in certain electrocardiographic parameters in children with IDA. These findings suggest that iron deficiency may influence cardiac repolarization and highlight the potential role of ECG monitoring in the early stages.
Content Analysis and Antimicrobial Activity of Pyrolysis Liquid Obtained From Oak Residue (Quercus Sp.)
(Corvinus University of Budapest, 2025) Koç, I.
The search for organic pesticides continues due to the adverse effects of chemical pesticides used against plant pathogens such as bacteria, and fungi. The evaluation of agricultural and forestry residues within this framework is of vital importance from many perspectives. This study was conducted to determine the activity of pyrolysis liquid (PL) prepared at different concentrations ranging from 1% to 25%, v/v against certain plant pathogenic bacteria and fungi. The PL was obtained from a company that produces charcoal through carbonization at temperatures ranging from 100 to 550 °C. The study was carried out in vitro under a Randomized Plot Design with four replications. The content analysis of PL was determined using solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry (GC-MS). The detection of antifungal activity was performed using the Poisoned Food Method on Malt Extract Agar, while antibacterial activity was determined using the Agar Well Diffusion Method on Mueller-Hinton Agar. Statistical analyses of the obtained datasets (factorial ANOVA) indicated that both the statistical significance of the concentration (P=0.001) and its practical importance (effect size=0.9953) were significant. It was determined that concentrations of PL at 2% and above (v/v) completely inhibited fungi populations. It is suggested that the PL used in this study has potential antifungal activity and can be utilized for various purposes, particularly in plant protection activities. © 2025, ALÖKI Kft., Budapest, Hungary.

Synthesis, Spectroscopic Characterization, and Biological Evaluation of a Novel Acyclic Heterocyclic Compound: Anticancer, Antioxidant, Antifungal, and Molecular Docking Studies
(MDPI, 2025) Alhilal, Mohammad; Alhilal, Suzan; Sabancilar, Ilhan; Gomha, Sobhi M.; Elhenawy, Ahmed A.; Ouf, Salama A.
Background/Objectives: This study aimed to synthesize a novel, high-molecular-weight acyclic heterocyclic compound, compound 5, via a one-pot reaction between Trichloroisocyanuric acid (TCCA) and ethanolamine, and evaluate its anticancer, antioxidant, and antifungal activities. Methods: Its complex tetrameric structure, assembled through N-N linkages, was unequivocally confirmed by a full suite of spectroscopic techniques including IR, 1H & 13C NMR, 2D-NMR, and high-resolution mass spectrometry (LC/Q-TOF/MS). The MTT assay was used to assess the anticancer activity of compound 5 against four different human cancer cell lines. Results: The findings indicate that human colon (HT29) and ovarian (OVCAR3) cancer cells were sensitive to the treatment, whereas brain (glioblastoma) (T98G) cancer cells were resistant. The most pronounced cytotoxic effect was observed in pancreatic (MiaPaCa2) cancer cells. Notably, compound 5 exhibited potent antifungal properties, achieving 100% inhibition of the pathogenic water mould Saprolegnia parasitica zoospores at 100 mu M after 10 min. Molecular docking studies corroborated the biological data, revealing a high binding affinity for key cancer and fungal targets (Thymidylate Synthase and CYP51), providing a strong mechanistic basis for its observed activities. Conclusions: These findings establish compound 5 as a promising dual-action agent with significant potential as both a targeted anticancer lead and an eco-friendly antifungal for applications in aquaculture.
Hegel's Concept of Desire in the Context of Deleuze's Critique of Idealist Desire
(Beytulhikme Felsefe Cevresi, 2025) Yirmibes, Mert Can
Deleuze critiques the conceptualization of desire through lack and acquisition within idealist philosophy and claims that the idealist notion of desire reduces production to the production of fantasy. He proposes an alternative concept of desire, which can be understood through pure production. This critique allows for a re-evaluation of Hegel's concept of desire as an idealist philosopher. This paper examines Hegel's concept of desire in the Phenomenology of Spirit, by focusing on the concepts of destructiveness, production, and satisfaction. The paper argues that Deleuze's understanding of desire as production is indeed present within Hegel's concept of desire, but production cannot be regarded as the fundamental characteristic of desire as seen in Deleuze's framework. The article concludes that, based on Hegel's analysis, lack and destructiveness are necessary conditions for the productive activity in desire, and that Deleuze's critique of idealist desire underlying the relationship between lack and acquisition is not sufficiently convincing, regarding Hegel's analysis of desire.
