- MakaleYalnız künye2026Scopus SJRQ2Comparative investigation of composite-metal lap joints with mono-adhesive and thermoplastic-reinforced mixed adhesive at elevated temperatures
Erbayrak, Engin; Eker, Beril; Colak, Murat
This study primarily examines the strength of a single lap joint having a mixed adhesive overlap consisting of a single adhesive and its thermoplastic reinforced state under varying temperatures. In the single lap joint, Titanium-Boron reinforced A356 aluminum was employed as the metal adherend, while plain woven glass fiber-reinforced epoxy (GFRE) was employed as the composite adherend. In the application of the mixed adhesive overlap, the brittle adhesives were employed in the middle section of the lap joint, while the reinforcement of the thermoplastics was employed on the adhesives at both sides of the lap joint. The single lap joints were subjected to tensile tests at 1 mm/min loading rates under room temperature and 120 °C, which is the melting point of the copolyester. In the numerical analysis, the cohesive zone model was applied in order to define the adhesives; however, elastic isotropic and orthotropic material behaviors were employed for the metal and composite adherends, respectively. Eventually, it is determined that the strength of a mixed adhesive lap joint consisting of a single adhesive and its thermoplastic reinforced state is better than a lap joint made with the mono-adhesive alone. Although literature suggests that mixed adhesive overlaps can be formed using at least two different adhesives (one ductile and one brittle), this study demonstrated that a mixed adhesive zone can be created using a single adhesive and thermoplastic reinforcement.

Erdoğan, Yaşar
Varroa destructor is a destructive ectoparasite of honeybees (Apis mellifera). This study investigates the chemical composition and bioactivity of essential oils obtained from three medicinal plants (Origanum acutidens, Satureja hortensis, and Juniperus communis). The chemical components of the essential oils were determined by Gas Chromatography-Mass Spectrometry (GC-MS). These oils were evaluated for their acaricidal, repellent, and insecticidal activities against V. destructor, as well as their lethal effects against honeybee larvae. The results revealed that the essential oils of O. acutidens (LC50: 2.18, LC90: 6.07 µL/L) and S. hortensis (LC50: 1.79, LC90: 5.77 µL/L) exhibited strong acaricidal effects, while those of J. communis (LC50: 3.75, LC90: 4.16 µL/L) exhibited moderate activity. S. hortensis showed the highest repellent effect against V. destructor (ED50: 0.44, ED90: 1.25 µL/L), followed by O. acutidens (ED50: 0.58, ED90: 4.22 µL/L) and J. communis (ED50: 0.87, ED90: 46.3 µL/L). Furthermore, the larval mortality rates remained below 5% in all treatments, indicating negligible toxicity to honeybee larvae. Overall, this study highlights for the first time the comparative acaricidal and repellent efficacy of these three essential oils under identical experimental conditions, emphasising their potential as natural and environmentally friendly alternatives for controlling V. destructor. Further research is needed to optimise application methods and evaluate long-term effects under field conditions.

Yarımkaya, Erkan; Şenlik, Zeynel Abidin; Demir, Mehmet; Töman, Ufuk; Kul, Murat; Türkmen, Mutlu
The individual, environmental and systemic physical activity (PA) barriers experienced by individuals with autism spectrum disorder (ASD) in daily life may become more complex after a devastating disaster such as an earthquake. In order to effectively combat the high level of inactivity that may occur after an earthquake in individuals with ASD, PA barriers must be determined before the earthquake. However, no description is provided in the literature regarding the PA barriers experienced by individuals with ASD after the earthquake. The purpose of this phenomenological study is to examine parents’ experiences regarding PA barriers experienced by individuals with ASD after the 2023 Kahramanmaraş earthquakes in Türkiye. Fifteen parents of individuals aged 8 and 31 with ASD were interviewed. The interviews were analyzed using both inductive and deductive content analysis approach. Three overarching themes were found: (1) the effects of PA on individuals with ASD, (2) post-earthquake PA barriers, and (3) the consequences of lack of PA in individuals with ASD. The results revealed that parents were aware of the benefits of PA and directed their children with ASD to PA before the earthquake. However, after the earthquake, parents encountered PA barriers that they had to overcome, and this negatively affected the children with ASD.

Erbayrak, Engin; Colak, Murat; Noberi, Cansu
This study evaluates the strength of double lap joints composed of metal composite adherends and epoxy adhesive subjected to low impact energies (20 J, 40 J). The study was carried out through experimental and numerical methods to understand the strength of lap joints comprehensively. In the production of double lap joints, A356 aluminum and grain-refined aluminum adherends were used as the metal components. To refine the grain structure, titanium (Ti) and boron (B) were added to the liquid metal at a rate of 0.01% of the total metal weight (A356-TiB). The composite laminates consisted of glass/epoxy and aramid/epoxy, made with unidirectionally oriented fibers. Araldite 2015 epoxy adhesive, available in both unreinforced and copolyester-reinforced forms, was utilized to bond the metal and composite materials. In the numerical analysis of double-lap joints, the metal and composite adherends are modeled using 8-node solid elements, while the adhesive is represented by 6-node pentahedron cohesive elements. Furthermore, a surface-to-surface, two-way treatment of contact was created between the impactor and the metal adherend. Consequently, the maximum impact loads obtained from the numerical analysis are in good agreement with the experimental results for both impact energies.

Silver nanoparticles (AgNPs) are known for their significant anticancer and antimicrobial activities in the field of medicine. In the present study, AgNPs were synthesized using a microwave-assisted green synthesis process, in which Ag(I) ions were reduced by organic compounds extracted from the leaves and stems of Phlomis linearis, an endemic plant which acted as both reducing and stabilizing agents. Although various species of the Phlomis genus have been studied in the literature, the synthesis of the nano-sized biogenic silver with reducing Ag(I) in the extract of the endemic plant P. linearis is reported here for the first study time, along with the evaluations of its bioactive properties. The obtained AgNPs were characterized by optical, structural, morphological, etc. techniques such as Ultraviolet–visible spectroscopy (UV–Vis.), Fourier-Transform Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), transmission electron microscopy (TEM), dynamic light scattering (DLS), and photoluminescence (PL). Gas chromatography − mass spectrometry (GC–MS) and FT-IR techniques were used in order to evaluate the biochemical-reduction mechanism. When their antimicrobial activities were determined by the well diffusion method on six bacterial strains, the results showed that P. linearis exhibited antimicrobial activity against all tested bacteria. Additionally, the investigation of the anticancer activity of the particles by using the MTS method on a breast cancer cell line (MCF-7) and a healthy human cell population (human umbilical vein endothelial cells [HUVEC]) revealed that our AgNPs were more cytotoxic toward the cancerous cells compared to the non-cancerous ones (p < 0.001).

Yarımkaya, Erkan; Bakkaloğlu, Hatice
Individuals with intellectual disabilities and their parents, who encounter many barriers in daily life, may experience even more serious problems when faced with a devastating disaster such as an earthquake. For effective earthquake preparation, it is important to identify these problems before the earthquake. However, studies examining the earthquake experiences of individuals with intellectual disabilities and their parents are quite limited. In this context, the aim of the current study was to explore the experiences of parents of individuals with intellectual disabilities who were affected by the 2023 Kahramanmaraş earthquakes in Türkiye. This study used the phenomenological qualitative research design. In this study, there were 16 parents, who have children with intellectual disabilities and participated in face-to-face interviews. Interview data were analyzed thematically. Two overarching themes were found: (1) low level of earthquake preparedness, and (2) inaccessible needs. The findings revealed that the majority of parents of individuals with intellectual disabilities made few preparations for the earthquake, could not access many of their needs during and after the earthquake, and could not find a special unit for individuals with disabilities to explain their problems.

Yarımkaya, Erkan; Aydemir, Uğur
Purpose: Advances in artificial intelligence (AI) have led to the increasing use of chatbots to promote physical activity (PA) through personalised guidance and interactive feedback. However, little is known about how AI chatbots can support parents of individuals with autism spectrum disorder (ASD) in promoting home-based PA. Understanding parents’ perspectives on the use of AI chatbots to promote PA may be critical for designing practical guidance and interventions for individuals with ASD. Therefore, the present study aimed to examine parents’ perspectives on the use of AI chatbots to promote PA among individuals with ASD using the Theory of Planned Behaviour (TpB). Method: Participants in this descriptive qualitative study were 16 parents (13 females and 3 males) who participated in one-on-one semi-structured interviews. The interviews were transcribed for analysis and later analysed using thematic line-by-line analysis. Results: The findings revealed that parents had positive attitudes towards the use of AI chatbots to promote PA among individuals with ASD. According to parents, AI chatbots were useful for learning new information about PA and increasing PA levels among individuals with ASD. On the other hand, parents stated that AI chatbots did not provide much detail about some PAs and that they did not understand some PA terms. Therefore, parents stated that they repeatedly gave AI chatbots commands/prompts for each PA and often needed expert support. Conclusions: Results indicated a need for guidance to parents on the use of AI chatbots to promote PA among individuals with ASD.

Ulay, Göksel; Akter, Mete; Çakıcıer, Nevzat; Ayata, Ümit
This study evaluated the effects of different weathering durations (168, 336, and 504 h) on surface hardness and adhesion strength of both heat-treated (1.5 h at 190 °C and 2 h at 212 °C) and untreated iroko (Chlorophora excelsa) wood surfaces after application of water-based varnish (WBV). Pendulum hardness (s) and pull-off adhesion (MPa) tests were performed after weathering. According to the results, in the untreated control group, hardness increased from 30 s to 45 s after 504 h of weathering, showing a 48% increase. In the samples treated at 190 °C, hardness increased from 25 s to 41 s after 504 h, showing a 61% increase. The highest increase was observed in the samples treated at 212 °C. Here, the hardness increased from 23 s to 44 s, representing a 91% increase after 504 h of weathering. The highest initial surface adhesion strength (5.30 MPa) was obtained in the unheated samples; however, this value decreased significantly after weathering. Although the initial adhesion strength was lower in the heat-treated samples, those treated at 212 °C for 2 h exhibited more stable weathering performance. The results show that the acceleration of weathering and the application of heat significantly affect the effectiveness of the varnish coating.

Erdoğan, Yaşar; Erdoğan, Ümmügülsüm
This study evaluated the effects of chokeberry (Aronia melanocarpa) fruit powder as a functional dietary supplement for honey bee (Apis mellifera) colonies, focusing on colony development, antioxidant defences, nutritional status, behaviour, and honey yield under field conditions. A total of 48 colonies were randomly assigned to four feeding treatments (control, 2, 5, and 10 g L−1 chokeberry supplementation), with six colonies per treatment in each apiary (n = 6 per apiary; n = 12 per treatment). The experiment was conducted as a balanced field trial across two apiaries. Colonies were fed sucrose syrup supplemented with chokeberry powder for 21 days. Following the feeding period, colonies were transferred to two high-altitude summer apiaries where colony development, flight activity, defensive behaviour, antioxidant biomarkers, and end-of-season honey yield were evaluated. Results demonstrated that chokeberry supplementation significantly improved colony development, with significant dose effects on brood area and bee-covered frames (both p < 0.001). Flight activity also increased with supplementation dose (p < 0.001), whereas defensive behaviour was not affected. Total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT) activity, and haemolymph total protein concentration all increased significantly with supplementation (all p < 0.001). End-of-season honey yield was significantly higher in supplemented colonies than in the control group (p < 0.001). Overall, these findings demonstrate that chokeberry fruit powder represents a promising functional dietary supplement capable of improving colony performance through the combined contribution of its nutritional composition and bioactive phytochemicals under practical field conditions.

Kutlu, Naciye; Gercek, Yusuf Can; Ecem Bayram, Nesrin
Monofloral Rhododendron spp. bee pollen is a remarkable bee product due to its functional components as well as its potential pharmacological effects. In this study, Rhododendron spp. bee pollen was dried by the microwave method as an alternative to the conventional drying method. Different combinations of microwave powers (140, 210 and 280 W) and sample weights (10, 20 and 30 g) applied during microwave drying (MWD) were determined by Central Composite Design. Drying time, total protein, total carotenoid, total phenolic-flavonoid compounds, and proanthocyanidin yields of dried pollen were determined and antioxidant activity tests (CUPRAC and DPPH•) were performed. The analysis results were optimized by response surface methodology (RSM) and the optimum drying conditions were obtained when the microwave power was 280 W and the sample weight was 30 g. The optimal conditions have been established to reduce drying time and enhance the content of bioactive compounds. As a result of optimization, the composite desirability (d) was found to be 0.8. Experimental and predicted values were close to each other. In conclusion, MWD has demonstrated efficacy as a drying technique by significantly reducing drying time while maintaining and enhancing the yields of bioactive compounds in monofloral Rhododendron spp. bee pollen. In comparison to conventional techniques, the application of MWD in the drying process of monofloral Rhododendron spp. bee pollen is demonstrably more efficient and sustainable.

Öner, Erdal; Artar, Pınar Tuğçe
Contact mechanics has played a central role in engineering progressing from early practices in ancient civilizations to the pioneering experimental studies of early scientists and more recently to advanced computational approaches. In modern research, functionally graded materials have gained increasing attention as their continuously varying properties enable the tailoring of stress fields, improvement of resistance to thermal and mechanical loads, and enhancement of the performance and reliability of layered systems.This study addresses the continuous contact problem of a two-layered medium composed of a functionally graded orthotropic layer (FGOL) placed over a functionally graded isotropic layer (FGIL). A rigid cylindrical punch applies a static concentrated load on the FGOL, while the lower surface of the FGIL is bonded to a rigid foundation. The layers are assumed to be unbonded at their interface, and frictionless contact conditions are imposed. To capture the effect of anisotropy, actual orthotropic materials are employed in the FGOL. An exponential through-thickness variation is adopted for the FGOL stiffness coefficients and density, and for the FGIL shear modulus and density. Under plane strain conditions, the contact formulation is reduced to a singular integral equation by applying the relevant boundary conditions. The equation is solved numerically using Gauss–Chebyshev integration techniques. The results provide detailed evaluations of contact lengths, stress distributions, critical load factors, and initial separation points as functions of selected nondimensionalized parameters and different orthotropic material choices, thereby contributing to a deeper understanding of the mechanics of graded layered systems.

Çıvracı, Sadık; Yalçın, Sakine; Onbaşılar, Esin Ebru
This study was carried out to determine the effects of seeds and roots of giant fennel (Ferula communis L.) on some performance characteristics of Apis mellifera caucasia L. colonies. Equalized colonies were distributed with 4 colonies for each group. In the study, 5 groups were arranged, and only syrup was given to the control group. On the other hand, 0.1% and 0.2% levels of root and seed of giant fennel were added to the syrup in the experimental groups. Measurements were made at 21-day intervals in the experiment. At the end of the experiment, supplemental feeding by adding fennel seeds and roots to the syrup provided a statistically significant increase in the number of bee frames, hive weight, nectar flow weight gain, and honey yield. Although the use of seed and root at the levels of 0.1% and 0.2% did not make a difference in these parameters, the use of the 0.2% level of seed had a more positive effect than the level of 0.1%. Usage of giant fennel seed and root increased total antioxidant status, total oxidant status, and oxidative stress index in honey according to the control group. The total antioxidant status in honey was increased statistically with the usage of 0.1% fennel seed. As a result of this study, it was concluded that the brood production and honey yield in honey bees and the antioxidant status in honey can be increased with the use of fennel seed and root, especially at the level of 0.2%, in supplementary feeding.

Ekincioğlu, Yavuz; Kepceoğlu, Abdullah; Çakir, Zehra; Şentürk, Şükrü
Nitrogen-rich heterocycles are attractive candidates for next-generation energetic materials because they can deliver high heats of formation while producing relatively benign, N2-rich decomposition products. In this work, three nitrogen-rich frameworks 3,6-bis(tetrazol-5-yl)−1,2,4,5-tetrazine (H2BTTz), 2,4,6-tris(tetrazol-5-yl)−1,3,5-triazine (H3TTT), and 2,3,5,6-tetra(tetrazol-5-yl)pyrazine (H4TTP) were investigated using a combined conformational sampling and density functional theory (DFT) approach. Initial conformational searches were carried out with the MMFF method, and the lowest-energy structures were optimised at the DFT/B3LYP/6-311++G(d,p) level a widely used compromise between accuracy and computational cost for nitrogen-rich energetic molecules. Electronic structure analyses included frontier molecular orbitals, Mulliken and natural population charges, and molecular electrostatic potential maps. Energetic performance was evaluated through heats of formation, detonation velocity and pressure, and impact sensitivity estimates. Topological descriptors such as ELF, LOL, and NCI were analyzed using Multiwfn program. The calculated HOMO–LUMO gaps (3.54-4.90 eV) indicate electronically stable molecular frameworks. Gas-phase formation enthalpies were converted to condensed-phase values using a sublimation correction, and detonation properties were estimated via the Kamlet–Jacobs equations. The predicted performance follows the order H4TTP > H2BTTz > H3TTT. Although their detonation performance is lower than that of FOX-7 and CL-20, these nitrogen-rich systems remain promising candidates for reduced-sensitivity energetic materials and merit further experimental investigation.

Akeren, İhsan; Koçak, Lokman; Özgöl, Mustafa; Demir, Mustafa
Social media, which is one of the platforms where online activities are most intensely observed, has become an indispensable element of daily life as it enables individuals to interact. The aim of this three-phase study was to develop a measure of social media interaction motivation (SMIM) among those who use at least one of these platforms, to test its validity and reliability, and then to examine its relationship with some variables that were found to be similar. SMIM increases unhealthy cyber behaviors such as fear of missing out (FoMO) and phubbing. Comparing the measures across the three studies, the means of SMD, FoMO, and phubbing do not differ by gender, except for the higher SMIMS scores of females in Study 2. However, these means increase dramatically with time spent on social media. Considering some limitations of the study, we present our suggestions for future studies.

Water is a significant element for the sustainability of life and is crucial for many aspects, such as agriculture, cities, ecosystems, industries, and people. This study focuses on municipal water quality assessments for urbanization activities and human health concerns when dealing with the sustainable city concept. For the first time, an integrated fuzzy decision-making framework is proposed to evaluate municipal water quality criteria with microbiological parameters, heavy metals, and other chemicals. For this aim, the eight main criteria and forty-four sub-criteria were specified to evaluate municipal water quality for a sustainable city. A case study was performed in Bayburt, Türkiye, to evaluate 130 water depots when dealing with a number of scenarios. Moreover, the Sustainable Development Goals (SDGs) 6.1 and 6.3 can be achieved through the study. Finally, this study presents how to develop safe and clean water management for the concept of a sustainable city.

Cage material selection in spinal fusion requires a trade-off among biological fixation, mechanical compatibility, subsidence resistance, and postoperative imaging. This structured narrative review compares titanium and polyetheretherketone (PEEK) cages across seven domains: osseointegration, modulus matching, endplate load transfer, surface biofunctionality, imaging, additive manufacturing and personalization, and geometry-guided architecture. Peer-reviewed literature indexed in PubMed/MEDLINE, Scopus, and Web of Science was considered from database inception through May 2026, with emphasis on comparative clinical studies, systematic reviews, meta-analyses, and mechanistic studies directly relevant to cage design. Preclinical studies favor porous and additively manufactured titanium for bone–implant integration, but a consistent fusion-rate advantage in anterior cervical discectomy and fusion (ACDF) has not been established. In lumbar surgery, lower subsidence has been reported in selected lateral lumbar interbody fusion cohorts, while results after transforaminal lumbar interbody fusion remain heterogeneous. PEEK retains advantages in radiolucency and intrinsic modulus matching, while surface-modified and porous PEEK can improve biological performance. Subsidence is not determined by chemistry alone; cage footprint, architecture, endplate preparation, fixation, and bone quality remain major modifiers. Current evidence therefore supports procedure and design-specific selection rather than universal replacement of either platform. Long-term comparative data and standardized definitions of fusion and subsidence remain limited.

In this study, the biostimulant potential of titanium dioxide (TiO2) nanoparticles was investigated to enhance sugar beet (Beta vulgaris L.) seed response to salt stress. Controlled applications were conducted at different NaCl (0–200 mM) and TiO2 (0–1,800 ppm) levels, and eight key morphological and physiological parameters were evaluated. In the first stage, the individual and interactive effects of the factors were examined using a two-way analysis of variance. Then, various machine learning-based regression models, primarily the Gradient Boosting algorithm, were used to numerically model plant responses. Based on the high-accuracy models, optimal application combinations were determined for each parameter and visualized using graphical surface analyses. Additionally, the most suitable overall TiO2 dosage for each salt level was calculated using a multi-criteria scoring system that assigned equal weight to all parameters. The results revealed that TiO2 exerts a regulatory and protective effect on plants against salt stress, with this effect varying with both dosage level and environmental stress severity. The study demonstrates that nanotechnological initiatives can be integrated into data-driven agricultural strategies to optimize stress management.

We consider an initial boundary value problem for a class of anisotropic parabolic Ni-Serrin type equations with nonstandard nonlinearity in a bounded smooth domain with homogeneous Dirichlet boundary condition. Because the nonlinear perturbation leads to difficulties (it does not have a definite sign) in obtaining a priori estimates in the energy method, we had to modify the Tartar method significantly. Under suitable assumptions, we obtain the global existence, decay and extinction of solutions.
