A novel insecticide acetamiprid detection in wastewater samples by quartz crystal microbalance sensor based on molecularly imprinting polymer and nitrogen sulphur co-doped carbon dots incorporated TiO2 nanoparticles
No full textA new type quartz crystal microbalance (QCM) sensor based on nitrogen sulphur co-doped carbon dots incorporated TiO2 nanoparticles (NSCTi) nanocomposite and molecularly imprinting polymers (MIPs) is presented for acetamiprid (ACE) detection. After the preparation of NSCTi nanocomposite by using microwave irradiation treatment and the hydrothermal method, QCM chip modified NSCTi nanocomposite was developed by using the interaction between gold and sulphur. Then, MIPs based on QCM chip modified NSCTi nanocomposite was designed via the spin coating method providing mono-layered and homogeneous QCM surface in presence of methacryloylamidoglutamic acid (MAGA) as monomer and N, N′-azobisisobutyronitrile (AIBN) as initiator. After the characterization investigations, the linearity in the range 1.0 × 10− 9 – 2.0 × 10− 8 M with a detection limit (LOD) of 3.3 × 10− 10 M was calculated for ACE. Finally, the developed QCM sensor was applied to wastewater samples with high recovery. © The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature 2026
Evaluation of aggregate-cement paste Interface: Effects of aggregate characteristics on acid attack and permeability of concrete
Full text linkThis investigation systematically evaluates the influence of aggregate type (basalt, white limestone, and brown limestone) and nominal size (10, 14, and 20 mm) on the characteristics of the interfacial transition zone (ITZ) and the durability of plain concrete, specifically its acid resistance and water permeability. The experimental program involved a comprehensive characterization approach. Aggregate surface roughness was quantified using a surface profilometer. The ITZ’s microstructural and mechanical properties were analyzed via SEM, XRD, and direct tensile testing. Durability was assessed by evaluating acid resistance—determined by mass and compressive strength loss after 30-day immersion in 5 % H 2 SO 4 —and water permeability, measured in accordance with BS EN 12390–8:2019. The findings revealed that fractured aggregate surfaces significantly enhanced bond strength over sawn counterparts. A key mechanistic insight is that the nature of roughness, not just its magnitude, governs performance: naturally fractured aggregates are significantly rougher, with basalt’s texture defined by high peaks (promoting mechanical interlocking) and limestone’s by deep valleys. Basalt’s chemical reactivity further improved the ITZ by consuming portlandite to create a denser, stronger interface, whereas limestone produced a more porous ITZ with unhydrated phases. Consequently, concrete incorporating basalt demonstrated superior acid resistance, with the least strength degradation and lowest permeability. White limestone performed moderately, while brown limestone showed the poorest resistance. Water penetration results aligned with these observations, confirming basalt concrete as the least permeable. For all aggregate types, using smaller sizes effectively mitigated acid damage and reduced permeability. The study underscores basalt’s suitability for acidic environments due to its reactivity and ITZ refinement, stressing that aggregate selection and size are critical for designing durable concrete in corrosive conditions
The effect of COPD stage on self-care management in COPD Patients: The mediating role of illness perception
Full text linkBackground: Determining the stage of COPD is essential for disease prognosis and management. Self-care management is among the basic elements of non-pharmacological treatment in COPD patients and is associated with illness perception. Objective: The current study aimed to investigate the mediating role of illness perception in the relationship between COPD stage and self-care management. Methods: The research was conducted in the chest diseases outpatient clinic of a hospital located in the eastern Mediterranean region between July 2024 and January 2025. The cross-sectional and predictive correlational research was completed with 145 patients. The patient descriptive form, the Brief Illness Perception Questionnaire, and the Self-Care Management Processes-Guarding Scale were used to collect data. Descriptive statistics were used in the data analysis, and SPSS Process Macro Model 4 was utilized to test the mediating role. Results: A positive and moderately significant relationship was identified between COPD stage and illness perception. A negative and moderate relationship was found between COPD stage and self-care management. Furthermore, a negative and highly significant relationship was determined between illness perception and self-care management. It was observed that COPD stage and illness perception were significant predictors of self-care management. Since the indirect effect of COPD stage on self-care management was significant, it was revealed that illness perception mediated COPD stage and self-care management. Conclusion: It is essential to assess COPD stage and illness perception when evaluating self-care management in COPD patients and in patient care. © 2025 Elsevier Inc
Comparative determination of factors affecting attitude level towards healthy nutrition
Full text linkHealthy eating habits are critical to the health and well-being of future generations. Many people worldwide do not receive enough vitamins and minerals due to malnutrition To eliminate these, it is necessary to determine the factors that support people's healthy eating habits. This study was conducted to determine the factors that affect healthy eating habits. There are three external factors to the study: (1) being an expert in food and drink, (2) having received formal education in health, and (3) receiving professional support (dietician support) in nutrition. The level of healthy eating was evaluated based on nutritional knowledge, feelings about nutrition, positive eating habits, and poor eating habits. In this context, an online survey was applied to 425 employees in the health sector (202 people) and the food and beverage sector (223 people). The data obtained were analyzed comparatively. The study results showed that the level of nutritional knowledge was equal in both groups. However, it was concluded that food and beverage sector employees were more sensitive to feelings about nutrition, positive eating, and poor eating habits than healthcare sector employees. While food and beverage sector employees are expected to constantly deal with food, which causes desensitization, it has been observed that they are stable and resistant to healthy eating. It has been concluded that although they have not received any formal health training, the information they have obtained through professional support (dietician) accelerates the process of developing healthy eating behaviors. This result has strengthened the power of the education variable affecting healthy nutrition. In addition, sensitivity to healthy nutrition is catalyzed by the professional profession. Dietician support indirectly reinforces this attitude. Thus, it has contributed to the development of healthy nutrition literature
Integration of emerging technologies in tourism and hospitality curriculum: An international perspective
Full text linkThis paper investigates the status of emerging technologies, how they can be integrated into the curriculum, the skills students can acquire through these technologies, and the employment opportunities they create in the tourism and hospitality industry. In the study, a content analysis was conducted on the curriculum of 65 undergraduate tourism and hospitality management programs, followed by an analysis of data from 28 academics to explore the role of emerging technologies in the curriculum. We have observed six core topics. Technology courses had the lowest proportion. We further observe four categories of skills that emerging technologies may provide students, highlighting their potential to shape future career opportunities. Building on these findings, the current study contributes to the literature by linking these skill sets — digital and technological, theoretical, operational, and managerial — to emerging job roles such as virtual reality tour designers, competent tourism developers, and AI-driven marketing specialists. Furthermore, the study identifies the domains where emerging technologies have the most relevance and outlines which purpose they may be included in the tourism and hospitality curriculum as a course. Thus, it forwards previous studies emphasizing the importance of emerging technologies. The study also suggests the implications for the literature, practice, and public policies. © 2025 Elsevier Lt
Comparison of machine learning models for sentiment analysis of big Turkish web-based data
Full text linkE-commerce sites have generated large amounts of unstructured data as they allow millions of users to generate product reviews. Thus, although there have been significant improvements in the characteristics of big data, such as speed and volume, developing various analysis techniques to monitor, understand, and extract useful information from this web-based data has become challenging. This study aims to analyze cosmetic products on a Turkish-based e-commerce website with sentiment analysis and to create a new domain-specific Turkish sentiment dictionary model with manual labeling. In the study, a Turkish sentiment dictionary consisting of 65,378 words was created by manually labeling 875,455 product reviews for 24 cosmetic brands sold on the Turkey-based trendyol e-commerce site, and sentiment analysis was performed using this dictionary. The dataset, divided into seven product groups, was analyzed using K-NN, SVM, DT, RF, and LR algorithms to address three classification problems. The algorithms were evaluated with comparative analysis using accuracy, precision, recall, and f-1 score metrics. SVM gave the highest performance result with over 93% accuracy, 92% precision, 93% recall, and a 91% f-1 score in all product groups. The dictionary model created for the cosmetics industry in the study helps businesses and researchers to use their resources more efficiently and save time by performing fast and low-cost analyses on large datasets of product reviews. Moreover, by analyzing customer feedback, brands can offer long-lasting and environmentally friendly products that align with customers' feelings. Thus, businesses have the opportunity to develop or improve products
Characterization of p-valent q-starlike functions through Hadamard product and Poisson distribution
Full text linkThis paper presents significant advancement in the study of multivalent functions by introducing three new subclasses of p-valent q-starlike functions, defined with respect to higher-order q-derivatives within the open unit disk of the complex plane (|z| <1). We utilized the Poisson distribution as a coefficient and applied the Hadmard product to derive several essential properties of these q-starlike functions, including distortion theorems and radius problems, particularly in case with negative coefficients. These findings enhance our understanding of the function behaviour and contribute to the broader mathematical discourse
Exploring the mediating role of virtual environment loneliness in the link between interpersonal relationship styles and social anxiety
Full text linkObjectives: As technology has transformed social interactions, the study
investigates whether virtual communication adequately fulfills individuals’ social
connection needs. This study explores the relationship between social anxiety,
virtual environment loneliness, and interpersonal relationship styles among a
diverse sample of 400 participants.
Methods: The study included 400 participants (N = 400), the majority of whom
were female (N = 254, 63.5%) and had at least a bachelor’s degree (N = 261;
65%). Participants completed the Environment Loneliness Scale, the Liebowitz
Social Anxiety Scale, and Interpersonal Relationships Scale. Multi-mediation
analysis was run to assess the potential mediating role of virtual loneliness.
Results: Results showed that an inhibitory relationship style was positively
correlated with social anxiety (r = 0.30, p < 0.01), while a nurturing relationship
style was negatively correlated (r = −0.21, p < 0.01). Mediation analyses revealed
that a subdimension of virtual environment loneliness, called virtual sharing,
significantly mediated the relationship between inhibitory relationship style and
social anxiety. However, no significant indirect effect was observed between
nurturing relationship style and social anxiety.
Conclusion: In conclusion, the current study provides insight regarding the
relationship between interpersonal relationship styles and social anxiety by
emphasizing the role of virtual sharing in this association. Successfully managing
social interactions is essential for improving individuals’ psychological wellbeing.
Future studies should further investigate these relationships to optimize
interventions for individuals struggling with social anxiety

The research was conducted in two phases with a methodological and randomized controlled design. In the first phase, after linguistic adaptation, the scale was administered to 131 diabetic patients and its content, construct, and criterion validity, as well as internal consistency, were examined. In the second phase, 60 patients with diabetic foot ulcers were randomly assigned to intervention (n=30) and control (n=30) groups. The intervention group received VR headset support during dressing, while the control group received standard care. Pain levels were measured using the Visual Analog Scale (VAS), and anxiety was assessed using the Spielberger State Anxiety Inventory before and after the procedure. The scale showed a high content validity index (0.90) and strong internal consistency (Cronbach's α=0.88). Construct validity was confirmed as unidimensional (CFI=1.00, RMSEA=0.01). Post-dressing pain and anxiety levels were significantly lower in the VR group compared to the control group (p<0.05). The use of VR during diabetic foot dressing was found to be effective in reducing pain and anxiety. The Turkish form of the Simplified 60-Second Diabetic Foot Screening Scale is a valid and reliable assessment tool
