Air Quality Forecasting Using Machine Learning: Comparative Analysis and Ensemble Strategies for Enhanced Prediction
(Springer Int Publ Ag, 2025) Aslan, Emrah; Alpsalaz, Feyyaz; Aslan, Emrah; Department of Computer Engineering / Bilgisayar Mühendisliği Bölümü
Air pollution poses a critical challenge to environmental sustainability, public health, and urban planning. Accurate air quality prediction is essential for devising effective management strategies and early warning systems. This study utilized a dataset comprising hourly measurements of pollutants such as PM2.5, NOx, CO, and benzene, sourced from five metal oxide sensors and a certified analyzer in a polluted urban area, totaling 9,357 records collected over one year (March 2004-February 2005) from the Kaggle Air Quality Data Set. A comprehensive comparison of ten machine learning regression models XGBoost, LightGBM, Random Forest, Gradient Boosting, CatBoost, Support Vector Regression (SVR) with Bayesian Optimization, Decision Tree, K-Nearest Neighbors (KNN), Elastic Net, and Bayesian Ridge was conducted. Model performance was enhanced through Bayesian optimization and randomized cross-validation, with stacking employed to leverage the strengths of base models. Experimental results showed that hyperparameter optimization and ensemble strategies significantly improved accuracy, with the SVR model optimized via Bayesian optimization achieving the highest performance: an R2 score of 99.94%, MAE of 0.0120, and MSE of 0.0005. These findings underscore the methodology's efficacy in precisely capturing the spatial and temporal dynamics of air pollution.

(Springer, 2025) Rymbai, Heiplanmi; Ercisli, Sezai; Sulusoglu Durul, Melekber; Kilicgun, Hasan; Bayyigit, Ismail; Colak, Aysen Melda
Prunus nepalensis is an important wild edible fruit tree of the eastern Himalayas, India. The fruit is known as a rich source of bioactive ingredients, pigmentation, and a distinctive organoleptic feature; however, the information available is scattered and focused mainly on the content of compounds in an isolated manner. The bioactive substances and pigmentations of P. nepalensis, as well as their potential applications were therefore thoroughly explored. All the data and literature were collected and analyzed. Sohiong fruits, had a unique blend of high titratable acidity, pH, citric acids, ascorbic acid, and total soluble solids (TSS). The proximate analysis revealed a high total carbohydrate, reducing sugar, total sugar, glucose, fructose, sucrose, crude oil, crude fiber, and ash content of fruits. A considerable amount of macro and micro mineral and nutritional content, including N, P, K, Ca, Mg, Zn, S, Na, and Fe, was recorded. The pulp and peel pigmentation of fruits was mainly due to the accumulation of anthocyanin (293-341 mg/100 g), including carotenoids, beta-carotene, flavonoids, and flavanol. A high content of ferric reducing ability of plasma (FRAP), total tannin, reduced glutathione, and hydroxyl radical activity are evidence of high antioxidants. Advancement in the development of novel extraction technologies has also improved the recovery efficiency of anthocyanin from Sohiong fruits. Sohiong fruits had high levels of bioactive substances and pigments. These fruits can be potentially used in value addition, food processing, and pharmaceutical applications as dietary supplements and alternative sources of edible color.

(Springer, 2025) Keskin, Cumali; Sabancilar, Ilhan; Kaya, Seckin; Mendes, Mehmet; Keskin, Cumali; Eftekhari, Aziz; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri Bölümü
Wood vinegar, also known as pyroligneous acid, is an organic liquid byproduct of wood pyrolysis, rich in compounds such as acetic acid, phenols, and ketones. This study aimed to evaluate the antioxidant and anticancer properties of wood vinegar derived from oak (Quercus sp.) residues (WVO) and hazelnut shells (Corylus avellana L.) (WVH) under in vitro conditions. Method: Wood vinegars obtained from oak trash and hazelnut shell waste were tested for biological activity. The antioxidant capacity was assessed using the copper(II) reducing antioxidant capacity (CUPRAC) method. Cytotoxic effects were evaluated using the MTT assay on healthy human endothelial cells (HUVEC) and two cancer cell lines (HT29-colon adenocarcinoma and U2OS-osteosarcoma) at concentrations ranging from 1.25% to 20% (v/v) over 24, 48, and 72-hour exposure periods. The results revealed significant interactions between vinegar type, concentration, and exposure duration. Notably, the 10% and 20% (v/v) concentrations produced significantly different absorbance values compared to lower concentrations across all time points. A dose-dependent decrease in cell viability was observed, particularly in the cancer cell lines, while healthy cells exhibited relatively higher resistance. The study demonstrates that wood vinegar exhibits promising antioxidant and selective anticancer properties, with cytotoxic effects being more pronounced at higher concentrations. These findings suggest that wood vinegar may offer potential as a natural anticancer agent. Further research is warranted to elucidate the underlying mechanisms and to explore their possible therapeutic applications.

(Springer, 2025) Derviş, Sibel; Dervis, Sibel; Ozer, Goksel; Turkkan, Muharrem; Bozoglu, Tugba; Alkan, Mehtap; Erper, Ismail; Department of Organic Agriculture / Organik Tarım Bölümü
Fusarium dry rot is a significant fungal disease impacting postharvest potato tubers worldwide, leading to substantial losses in tuber quality, nutritional value, and seed viability. In Kyrgyzstan, where potato is a staple crop, the disease poses a critical threat to food security. This study aimed to identify and characterize Fusarium species associated with dry rot in stored potatoes from the Osh region, a major potato production area facing severe postharvest challenges. Surveys were conducted in 34 potato storage facilities across four districts, and symptomatic tubers were collected. Fifty-four Fusarium isolates were obtained and subjected to a comprehensive characterization approach, including morphological assessments, molecular analyses using iPBS markers based on retrotransposons, DNA sequencing of the translation elongation factor-1 alpha (TEF1) locus, and pathogenicity tests on the 'Soraya' potato cultivar. Fusarium sambucinum was the most prevalent species (50%), followed by F. oxysporum (similar to 17%), F. flocciferum (similar to 11%), F. equiseti (similar to 9%), F. proliferatum (similar to 5%), F. acuminatum (similar to 4%), F. solani (similar to 2%), and F. venenatum (similar to 2%). Morphological identifications were supported by iPBS2395 primer analysis, which revealed distinct DNA fingerprinting patterns among the isolates. Phylogenetic analysis of TEF1 gene sequences further confirmed species identifications, demonstrating strong congruence between morphological, iPBS, and TEF1 data. Pathogenicity tests revealed varying levels of virulence across species, with F. sambucinum exhibiting the highest overall virulence and mean lesion sizes comparable to those of F. flocciferum, while F. equiseti and F. solani showed significantly lower virulence. Except for F. sambucinum, all other Fusarium species represent first reports in Kyrgyzstan, with F. flocciferum being reported globally for the first time as a causal agent of potato dry rot. This study provides a comprehensive assessment of the Fusarium species involved in dry rot in the Osh region, highlighting the dominance of F. sambucinum and the need for enhanced management strategies to mitigate postharvest losses and strengthen food security in Kyrgyzstan.

(Routledge Journals, Taylor & Francis Ltd, 2025) Karadaş, Halil; Karadas, Halil; Culha, Ali; Department of Child Development / Çocuk Gelişimi Bölümü
There is considerable literature on the challenges of refugee students, including the low performance of refugee students. However, we also know that some refugee students, although very few, show high performance in schools, and the achievements of these students are often overlooked. Intending to this gap in knowledge, therefore this qualitative phenomenological study, aims at exploring the possible sources behind the success of refugee students with high academic performance by using the opinions of school administrators, teachers, and students, triangulated with school observations. Findings indicate that the inclusive school environment, individual characteristics, family, and community-based engagement play a significant role in the emergence of this high academic. performance. Further conclusions and implications for education stakeholders tending to refugee academic performance are fully discussed.
Rapid Adsorption of Methylene Blue by Synthesizing Zinc Oxide Nanoparticles From Ocimum Basilicum L. Waste
(Springer, 2025) Baran, Ayşe; Solmaz, A.; Baran, A.
In this study, zinc oxide nanoparticles (ZnONp) were synthesized from Ocimum basilicum L. (ObL-ZnONp) plant wastes by green synthesis method to remove methylene blue (MB) dye, which has toxic effects on the environment. In batch adsorption studies, the effects of pH (3-11), ObL-ZnONp amount (0.0312-1.25 g/L), time (0-30 min), initial MB concentration (2-64 mg/L) and temperature (25-45 degrees C) were tested to determine the adsorption mechanism. The obtained results were tested with Pseudo first order (PFO), Pseudo second order (PSO), Elovich and Intraparticle diffusion kinetic models and evaluated in Freundlich, Langmuir, Temkin and Dubinin-Radushkevich isotherm models. Also 6 different error functions were used to interpret the results. Additionally, the morphological properties of the synthesized ObL-ZnONp were characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis. In addition, desorption tests were also performed. According to the obtained results, the most suitable kinetic and isotherm models were determined as PSO (R2: 0.999) and Freundlich (0.991), respectively. In addition, while more than 90% removal efficiency was achieved in 4 min, the maximum adsorption amount was determined as 21.41 mgMB/gObL-ZnONp. This study determined that Np synthesized at low cost was quite effective in MB removal.

(Taylor & Francis Ltd, 2025) Kutlu, İzzettin; Department of Architecture / Mimarlık Bölümü
The application of developing computer technologies such as artificial intelligence (AI), deep learning (DL), and machine learning (ML) on digital image data can help in monitoring, controlling, and preserving cultural heritage buildings. Defects such as mortar losses, joint damage, discoloration, erosion, cracks, vegetation, leakage, and vandalism seen in cultural heritage buildings negatively affect their structural health. There are a limited number of studies on the use of artificial intelligence and integration at cultural heritage buildings. This study includes the research and bibliometric analysis of existing studies. In the study, structural damage detection techniques performed using AI-assisted image processing techniques are summarized, and deep learning techniques applied, especially in the conservation of heritage sites, are detailed. The study found a significant deficiency in the number of applications and research in this field, particularly within T & uuml;rkiye. AI-assisted digital inspections provide useful data for studies to be conducted in this field and increase the level of confidence in the damage detection of heritage buildings. As a result, today, artificial intelligence, the effective use of which is increasing rapidly, can be integrated into many fields and enables interdisciplinary studies.

(Taylor & Francis Ltd, 2025) Bayram Değer, Vasfiye; Gulcicek, Atilim; Sayili, Ugurcan; Bayram Deger, Vasfiye; Erel, C. Tamer; Senturk, Levent M.; Department of Nursing / Hemşirelik Bölümü
Objective: This study aimed to evaluate the prevalence and severity of menopausal symptoms among perimenopausal women in a rural area of southeastern Turkey and their association with sleep quality, depression and sociodemographic and lifestyle-related factors. Methods: This cross-sectional study included 122 perimenopausal women aged 40-55 years residing in southeastern rural Turkey. Participants completed the Beck Depression Inventory (BDI), the Menopause Rating Scale (MRS) and the Pittsburgh Sleep Quality Index (PSQI), alongside demographic data collection. Results: The median age was 46 years (43-49 years). Higher MRS scores were significantly linked to a sedentary lifestyle, poor self-rated health and concerns about partner infidelity. MRS total scores were moderately correlated with global PSQI scores (r = 0.49, p < 0.001) and strongly correlated with BDI scores (r = 0.71, p < 0.001). Severe menopausal symptoms were significantly associated with poor sleep quality (odds ratio [OR] = 2.62; 95% confidence interval [CI]: 1.16-5.95), mild to severe depression (OR = 4.78; 95% CI: 2.08-10.98) and poor self-rated general health (OR = 2.76; 95% CI: 1.03-7.41), even after adjusting for age, parity and body mass index. Conclusions: Perimenopausal women in southeastern rural Turkey experience severe menopausal symptoms that are significantly associated with self-rated general health, sleep quality and depression.
Hamed-Troyansky, Vladimir. Empire of Refugees: North Caucasian Muslims and the Late Ottoman State
(Burhan Caglar, 2025) Yelbaşı, Caner; Department of History / Tarih Bölümü
The exile and settlement of North Caucasians in the Ottoman Empire is not well-studied in English academic literature. Vladimir Hamed-Troyansky's book is a well-researched work that helps fill this gap in the literature. It explores various aspects of North Caucasian exile and settlement, analysing both state perspectives-through a wide range of archival sources- and the experiences of the displaced people. Particularly significant is its use of letters written by the refugees (muhacirs), which amplify their voices and integrate them into academic discourse for the first time.
Neoscytalidium Dimidiatum as a Postharvest Pathogen Affecting Solanaceous Vegetables
(Wiley, 2025) Derviş, Sibel; Ozer, Goksel; Turkolmez, Sahimerdan; Turkkan, Muharrem; Dervis, Sibel; Department of Organic Agriculture / Organik Tarım Bölümü
Neoscytalidium dimidiatum, a member of the Botryosphaeriaceae family, is an emerging global plant pathogen. Although recently reported on various hosts in T & uuml;rkiye, its impact on commercially available vegetables remained undocumented. This study provides the first report of N. dimidiatum causing postharvest decay in the eggplant (Solanum melongena L.), pepper (Capsicum annuum), potato (Solanum tuberosum), and tomato (Solanum lycopersicum) obtained from local Turkish markets in 2023. The pathogen was identified through morphological characterisation and molecular analysis targeting the internal transcribed spacer (ITS) region, translation elongation factor 1-alpha (tef1), and beta-tubulin (tub2) gene sequences. The pathogenicity of N. dimidiatum was confirmed through Koch's postulates at 28 degrees C, and its temperature-dependent effects were assessed on solanaceous vegetables. Disease progression, measured by the area under the disease progress curve (AUDPC), was strongly influenced by temperature. No disease was observed at 12 degrees C. At 18 degrees C, limited disease development occurred in the eggplant and potato. AUDPC values increased significantly at 25 degrees C, generally peaking at 30 degrees C, with some hosts showing similar levels of disease severity at 35 degrees C. These findings highlight the critical role of postharvest temperature control, particularly rapid cooling and cold storage, in minimising losses caused by N. dimidiatum. This is the first report of N. dimidiatum as a postharvest pathogen affecting the eggplant, pepper, tomato fruits, and potato tubers, and the first record of this pathogen on the eggplant and pepper globally, expanding its known host range and reinforcing its significance as an emerging threat to global agriculture.

(Univ Sao Paolo, 2025) İçke, Sibel; Çifçi, Sema; Department of Nursing / Hemşirelik Bölümü; Department of Midwifery/ Ebelik Bölümü
Objective: This study aims to examine the satisfaction levels of Syrian migrant pregnant women living in Mardin with prenatal care services and the factors influencing their satisfaction. Method: This is a cross-sectional study. The population of the study consisted of Syrian pregnant women who applied to Mardin Training and Research Hospital between August 15 and September 16, 2023. A total of 146 Syrian pregnant women who met the inclusion criteria participated in the study. The sociodemographic information form and the Prenatal Care Satisfaction Scale were used as data collection tools. Results: The rate of those who received prenatal care from a midwife/nurse is 80.1% and those who received less than 4 prenatal care was 89.7%. The most common reason for not receiving adequate prenatal care was lack of information with a rate of 39.7%. The mean score of the PCSS was 73.39 +/- 14.78. Conclusion: The study findings indicate that lack of information is one of the major barriers to healthcare access for migrant pregnant women. In addition, receiving prenatal care services from midwives/nurses affected satisfaction with prenatal care.
Effects of Travel Agency Technological Leadership on Tour Guides' Use of Social Media Sharing Behaviors
(Cognizant Communication Corp, 2025) Arabacioglu, Dilan; Dedeoglu, Sevgi Balikcioglu; Ilhan, Ibrahim
The current study aims to determine the effects of technology leadership by tourist agencies on the motivation of tour guides to engage in professional sharing behaviors on social media. The data for this study were collected through surveys from registered tour guides affiliated with a travel agency in Turkey. In total, 373 participants were reached. Partial least squares-structural equation modeling was used to examine the mediating role of motives for social media use in the effect of travel agencies' technology leadership on tour guides' Instagram use behaviors. The findings showed that the technology leadership of travel agencies affects the Instagram use behaviors of tour guides and that the motivation for social media use has a mediating role in this relationship. According to our research findings, as guides become more proficient in using Instagram, their reputation among individuals improves. Consequently, the number of professional posts and the visibility of guides on social media will increase, making them more appealing to a larger number of tourists. This study differentiates itself from others related to technology leadership in the literature, as it is the first to mention both technology leadership and tour guides' social media usage together.

(Galenos Publ House, 2025) Ayaydin, Zeynep; Ozcan, Nida; Mermutluoglu, Cigdem; Atmaca, Selahattin; Tekin, Ali Cem
Aim: Coronavirus disease-2019 (COVID-19) has been suggested to trigger the production of autoimmune antibodies and contribute to the development of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. This study aims to investigate the presence of ANCA among COVID-19 patients. Methods: This cross-sectional, prospective analysis included 200 COVID-19 patients with positive polymerase chain reaction test results for severe acute respiratory syndrome-coronavirus-2 and no history of autoimmune disease, recruited between June 2021 and November 2022. The control group included 50 age-matched healthy blood donors. The ANCA profile was assessed using the indirect immunofluorescence assay method with the EUROPLUS Granulocyte Mosaic EUROPattern test kit (EUROIMMUN, Germany) on sera samples of the patient and control groups. Results: Perinuclear ANCA (p-ANCA) was detected in 12 of 200 COVID-19 patients (6.0%) and cytoplasmic ANCA (c-ANCA) was detected in 15 of 200 patients (7.5%). No ANCA positivity was observed in the control group (0/50). ANCA positivity among COVID-19 patients (27 of 200, 13.5%) was statistically significantly higher than in the control group (p<0.05). ANCA positivity was significantly higher in intensive care unit (ICU) patients (21 of 77, 27.3%) compared to non-ICU patients (6 of 123, 4.9%) (p<0.05). Conclusion: ANCA presence in ICU patients supports the hypothesis that COVID-19 triggers ANCA synthesis and contributes to disease severity.

Calcium-Mediated Mitigation Strategies and Novel Approaches To Alleviate Arsenic Induced Plant Stress
(Elsevier Ireland Ltd, 2025) Faizan, Mohammad; Eren, Abdullah; Alam, Pravej; Iqbal, Sumera; Waheed, Zainab; Eren, Abdullah; Shamsi, Anas; Shahwan, Moyad; Department of Organic Agriculture / Organik Tarım Bölümü
One worldwide environmental concern is the presence of potentially hazardous elements (PTEs) in air, soil, and water resources. Arsenic is one of the PTEs that is thought to be the most poisonous and carcinogenic. Plants exposed to arsenic may experience several morphological, physiological, and biochemical changes-even at extremely low concentrations. Arsenic toxicity to plants varies with its speciation in plants (e.g., arsenite, As(III); arsenate, As(V)), with the kind of plant species, and with other soil parameters affecting arsenic accumulation in plants, according to new study on arsenic in the soil-plant system. Arsenic stress modifies metabolic cascades in plants at different developmental stages by affecting the pattern of gene expressions mediated by small non-coding RNAs (micro-RNAs), which are essential for plant adaptation to oxidative stress and play a key role in the moderation of numerous cellular processes. In this review, we investigated the impact of calcium (Ca2 +) on the toxicity of arsenic in plant and soil environments. Plant grown with arsenic exhibited enhanced arsenic uptake, increased oxidative stress and growth inhibition. Arsenic toxicity modulates carbohydrate, lipid, and protein metabolism along with DNA structure. Role of Ca2+, Ca channels and Ca sensors to signaling pathways also described briefly. A worldwide issue for humanity is the poisoning of soil ecosystems by arsenic. Its toxicity, tolerance, and phytoremediation of polluted soils utilizing calcium were the main points of the recent review, which also highlighted the significant mechanisms of arsenic in soil-plant systems.
