- MakaleAçık Erişim2027A hierarchical metaheuristic framework for CPT-based soil liquefaction prediction with Kolmogorov–Arnold Network variants
Günen, Mehmet Akif; Öztürk, Kaşif Furkan
Soil liquefaction is a critical geotechnical hazard that threatens the safety of civil infrastructure under seismic loading, necessitating robust and interpretable prediction models. This study proposes a hierarchical framework for CPT-based soil liquefaction prediction using meta-heuristic-optimized Kolmogorov–Arnold Network (KAN) variants. The framework follows a two-stage optimization strategy. First, six state-of-the-art meta-heuristic algorithms are statistically compared to identify the most effective optimization method. Second, the selected algorithm is employed to optimize six KAN variants, including FastKAN, EfficientKAN, FourierKAN, ChebyKAN, JacobiRKAN, and PadéRKAN. Statistical comparisons based on the Wilcoxon signed-rank test demonstrate that the Colony-Based Search algorithm (CSA) achieves lower objective-function values than the competing meta-heuristics (p<0.01) and is therefore adopted as the core optimization strategy. Performance evaluation reveals that the CSA-optimized ChebyKAN model achieves the highest predictive accuracy, with an F1 Score of 0.8875 ± 0.011 and an AUC of 0.9115 ± 0.013. Pairwise McNemar tests detected no statistically significant difference in classification decisions for any evaluated model pair (p>0.01). SHapley Additive exPlanations analysis identified qc, qc1N, and amax as the variables with the largest model-specific attributions, whereas d, c, and σv received lower attributions. A cost-sensitive error analysis further showed that ChebyKAN produced the lowest false-negative rate and the lowest asymmetric error cost under 5:1 and 10:1 false-negative-to-false-positive cost scenarios, supporting its conservative behaviour for safety-critical liquefaction screening. The results establish the proposed CSA–KAN framework as a reliable, high-accuracy, and interpretable solution for CPT-based soil liquefaction assessment in geotechnical engineering practice.

Oğuz, Yasin; Kaya, Haydar
This study proposes an analytical ultra wide-band (UWB) waveform design based on linear combination of Gaussian-modulated sine waves to prevent interference with existing narrowband systems, in accordance with the Federal Communications Commission (FCC) UWB spectral mask. The proposed model determines the common pulse duration and the center frequencies of the components in closed-form using the relationships among the number of components, the overlap of components and the design band frequency limits. As a result, UWB waveforms for different design scenarios can be generated without computationally intensive algorithms. The method was evaluated in terms of spectrum utilization efficiency (SUE) within the 3.1-10.6 GHz indoor FCC UWB band. Results show that same SUE can be achieved with fewer components by appropriate overlap level. Comparisons with existing studies demonstrate that the proposed approach provides high performance for similar component numbers while avoiding complex optimization-based models with high computational cost. Moreover, the normalized spectral form and SUE are preserved for different sub-band widths when the analytical parameters are updated according to the new frequency limits. The results demonstrate that the proposed method is an effective waveform design approach due to its low computational complexity, high SUE, and scalability to multi-subband full-band UWB designs.
- MakaleYalnız künye2027Serial mediating role of belonging and state mindfulness in the relationship between clinical learning environment and caring behaviors in nursing students
Özalp, Cemal; Tuncer, Metin; Kaya, Abdulsamed; Şahin, Fatih
Aim: The study aimed to examine the relationship between clinical learning environment and caring behaviors in nursing students and to test the serial mediating roles of belonging and state mindfulness in this relationship. Background: The psychosocial mechanisms linking the clinical learning environment to caring behaviors remain unclear, particularly the combined roles of belonging and state mindfulness. Design: The study had a cross-sectional design and was conducted in line with the STROBE guidelines. Methods: The sample consisted of 452 undergraduate nursing students studying at a state university in Turkiye. The data were collected between December 2025 and January 2026 using the Personal Information Form, Clinical Learning Environment Scale, Nursing Department Belonging Scale, State Mindfulness Scale, and Caring Behaviors Inventory. Results: The clinical learning environment was found to be positively correlated with sense of belonging (B = 0.412, p < .001). Sense of belonging significantly predicted both State Mindfulness (B = 0.607, p < .001) and caring behaviors (B = 0.857, p < .001). State mindfulness is also a significant predictor of caring behaviors (B = 0.734, p < .001). Indirect effects analyses indicated that the clinical learning environment was associated with caring behaviors through sense of belonging and through the sequential pathway involving both sense of belonging and state mindfulness. However, the direct effect of the clinical learning environment on caring behaviors was not significant. Additionally, the indirect effect of the clinical learning environment on caring behaviors through state mindfulness alone was not significant. Conclusions: The results of the study showed that the clinical learning environment is associated with nursing students' caring behaviors indirectly through sense of belonging and state mindfulness, rather than directly.
- MakaleYalnız künye2027Efficacy of blue light-assisted ClO2 for Salmonella decontamination on basil leaves: inactivation kinetics, quality preservation, and microbiota dynamics
Lian, Yi; Liu, Songlin; Ozturk, Samet; Wei, Xinyao
Frequent Salmonella outbreaks associated with basil leaves highlight the need for effective postharvest decontamination. Conventional microbial sanitizers often fail to inactivate pathogens while preserving product quality, creating a demand for novel decontamination technologies suitable for basil. In this study, the microbial safety of basil under typical consumption scenarios was evaluated and a blue light-assisted ClO2 (COM) decontamination process for basil leaves was developed. Mathematical models were used to describe the microbial inactivation kinetics, and a systematic comparison was conducted against traditional single-chemical sanitizers (H2O2, HClO, ClO2, and 75% ethanol) in terms of microbial safety and final product quality. Results showed that simulated cooking scenarios, including pizza baking and hot soup immersion, were insufficient to reduce the Salmonella levels below the detection limit (<10 CFU/g) under a high initial load of 9.7 log CFU/g. Compared to the single-chemical treatments, 100 mg/L COM treatment achieved significantly higher decontamination (p < 0.05) by reducing Salmonella and background microbiota by 4.8 and 3.5 log CFU/g, respectively, with treatment time of 15 min. The inactivation kinetics of Salmonella showed a non-linear inactivation kinetics, which was captured by the Weibull model with a low RMSE value (RMSE = 0.16), although the AICc value (11.37) indicated limited model parsimony. Furthermore, the COM treatment significantly reduced bacterial richness (with the Chao1 index decreasing from 316 to 71) and effectively inactivated key spoilage organisms (Pseudomonas) as well as members of the Enterobacteriaceae, Actinomycetota, and Bacillota groups. Compared with the 100 mg/L ClO2 treatment alone (1.40 mg/kg), the 100 mg/L COM treatment resulted in a ClO2 residue concentration below the detection limit, without significantly altering visual appearance, color, chlorophyll content, total phenolics, or polyphenol oxidase activity (p > 0.05). Overall, blue light-assisted ClO2 treatment effectively reduced microbial contamination and reduced ClO2 residues while preserving the physical quality of basil, representing a promising decontamination approach for the fresh produce industry.

Torpuş, Kemal; Cengiz, Sevil
This study aimed to develop a flood fear scale. The study was designed as a methodological and cross-sectional study. The study was conducted with 1158 participants aged 18–65 residing in Türkiye’s Black Sea Region between February 15, 2025, and May 15, 2025. SPSS 25 and Amos 21 programs were used to analyze the data. The flood fear scale consists of four dimensions and 26 items. The Cronbach’s alpha coefficient was 0.948, and the scale explained 62.644% of the total variance. The model fit indices were χ2/ df = 3.444, RMSEA = 0.065, SRMR = 0.056, CFI = 0.921, IFI = 0.922, NFI = 0.893, and TLI = 0.912. The findings indicated that the flood fear scale provided valid and reliable for adults aged 18–65 residing in Türkiye’s Black Sea Region. The total scores obtainable from the scale range from 26 to 130, with higher scores indicating an increased level of flood fear. Scale can be used to assess flood fear in community-based disaster risk reduction efforts. It is recommended that validity and reliability studies of the scale be conducted in different cultures and geographical regions.
- MakaleAçık Erişim2027Design, Synthesis, and X-ray Characterization of Benzohydrazide Derivatives as Cholinesterase Inhibitors for the Treatment of Alzheimer’s Disease: An Experimental and Computational Approach to Biological Activity
Topal, Fevzi; Ünver, Hakan; Topal, Meryem; Çevik, Ulviye Acar; Kırboğa, Kevser Kübra; Işık, Mesut; Beydemir, Şükrü
In this study, a series of new benzohydrazide derivatives (1a-i) were synthesized, and characterized as potential cholinesterase inhibitors for use in the treatment of Alzheimer’s disease (AD). The inhibitory activities of the synthesized compounds against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes were evaluated using in vitro and in silico methods. IC50 values for AChE inhibition ranged from 29.50 to 46.21 nM, with compound 1c exhibiting the highest inhibitory potential at an IC50 of 29.50 nM. For the BChE enzyme, the strongest effect was observed with compound 1d at an IC50 of 55 nM. The synthesized derivatives exhibited higher inhibitory potential compared to the reference tacrine (IC50: 58.73 nM for AChE and 187.30 nM for BChE) against cholinesterase enzymes through both competitive and non-competitive inhibition mechanisms. Molecular docking (ΔG: -10.67 to -9.95 kcal/mol for AChE; -9.80 to -8.69 kcal/mol for BChE) and 100 ns molecular dynamics simulations supported the binding affinities and indicated the dynamic stability of the enzyme-inhibitor complexes, in agreement with the experimental inhibition data. In silico ADMET profiling indicated favourable drug-likeness and high predicted gastrointestinal absorption and blood-brain barrier permeability (TPSA 41.46-61.69 A2), and structural alert screening returned no PAINS matches. The findings suggest that these derivatives may serve as promising lead compounds for further investigation as potential cholinesterase inhibitors relevant to AD, pending experimental cytotoxicity evaluation.
- MakaleAçık Erişim2027Authorisation of notary publics on real property transactions in relation to the Turkish land registry system based on Cadastre 2014 vision
Çoruhlu, Yakup Emre; Inan, Halil Ibrahim; Çelik, Mehmet Ozgur; Alemdar, Alkan; Yildiz, Okan; Azadi, Hossein
The International Federation of Surveyors (FIG) has globally influenced land administration through its Cadastre 2014 vision and subsequent LADM standards. T & uuml;rkiye has been modernizing its land registry and cadastre system accordingly. The General Directorate of Land Registry and Cadastre (GDLRC) manages approximately 17 million annual transactions, including about 3.4 million conveyancing (long-term averages). To reduce congestion in Land Registry Offices (LROs), notaries were authorized to issue sales contracts in June 2022. This study investigates the effects of this change within the Cadastre 2014/2034 framework in terms of the maturity of the Turkish Land Administration System (LAS) and also by linking the issue to broader debates within land management and governance. A survey of 140 GDLRC experts revealed that notary involvement currently offers limited time and financial benefits to citizens and does not significantly reduce LRO workload. The central factor for this limitation is evaluated to be the maturity of Turkish LAS. On the other hand, the initiative aligns with Cadastre 2014's fifth statement, which advocates public-private collaboration, and therefore it should be further evolved. Within this evolution, administrative/managerial fixes and training programmes for notaries in the short term, management of all internal and external RRRs via LAS as a spatial data infrastructure service in line with LADM standards in the medium term, and betterment of institutional coordination, public responsibility development and capacity building in the long term are proposed for a better eventual land administration and management towards local and national good land governance.

Yilmaz, Banu; Erdogan, Serkan
This study examines the transformation of the Ottoman Empire's foreign policy during the Tanzimat period and the construction of the empire's image in Europe through the life and diplomatic activities of Alexandros Kalimaki Bey, a prominent diplomat. The main objective of this article is to analyze the career of Kalimaki, who was of Romanian origin and from a Greek family in Phanar, and who stands out as the first non-Muslim subject of the Ottoman Empire to serve as a permanent ambassador to Europe, particularly his crisis management during the Hungarian Refugee Crisis, within its historical context. The research proceeds with a chronological and qualitative method based on primary archival documents of the Ottoman Ministry of Foreign Affairs and Kalimaki's diplomatic reports sent from London and Paris. Data obtained from archival documents have been evaluated within their historical context by considering them alongside studies in the literature. Through this method, the transformation and crisis management processes in Ottoman foreign policy have been qualitatively assessed through the diplomatic correspondence and reports of the period. Within this framework, the study also aims to highlight the interaction between Kalimaki Bey's personal diplomatic capacity and the new diplomatic approach adopted by the Ottoman State after the Tanzimat reforms.

Deniz Ozturk, Yasemin; Peker, Iskender
The 6 February 2023 earthquakes caused catastrophic losses across 11 provinces of T & uuml;rkiye. To meet urgent shelter needs, extensive tent and container settlements were rapidly established; over time, however, these sites proved highly vulnerable to multi-hazard events. This study investigates the spatial and temporal distribution and impacts of fires, floods, and storms on temporary shelters over a two-year period following the earthquakes. In total, 306 events were identified across eight provinces - 155 fires, 147 floods, and 4 storms - damaging 5,075 containers and 420 tents, and causing 16 deaths and 67 injuries. Seasonal factors played a critical role of these hazards. As the earthquakes occurred during winter, the region's cold, rainy conditions led to frequent flooding and numerous heating-related tent fires, particularly in winter and early spring. March recorded the highest number of events due to intense rainfall, storms, and elevated heating demand. Vulnerable groups - including children, workers, and refugees - were disproportionately affected, with children accounting for six fire-related fatalities. Overall, the results highlight the seasonal nature of multi-hazard events in temporary shelter areas and emphasise the need for climate-sensitive planning, hazard mitigation measures, and improved safety standards in post-disaster temporary settlements.
- MakaleAçık Erişim2026Electricity Prices, Technology, Productivity, And Environmental Degradation: Implications For Financial Stability
Çakir, Mehmet Ali; Ökte, Mehmet Kutlughan Savas
The limited availability of fossil fuels and the financial pressure they create for countries that do not have the resources have led countries to search for new energy sources. In particular, renewable energy sources and therefore electrical energy obtained from these sources have been proposed in the literature as an alternative to fossil fuels. Thus, this study investigates the impact of electricity prices on financial stability in European Union countries from 2010 to 2021 using Driscoll Kraay fixed effects estimation. Financial stability is measured using the bank z-score, while productivity-intensive technology, environmental quality, and economic growth are included as control variables. The findings indicate that an increase in electricity prices negatively affects the bank z-score. In contrast, productivity-intensive technology positively impacts the bank z-score. Similarly, environmental quality contributes to an increase in the bank z-score. Additionally, economic growth enhances financial stability. Considering that rising electricity prices negatively affect financial stability, policymakers should encourage companies to produce electricity from renewable sources, such as solar panels or wind turbines. This can be supported through incentives such as tax breaks or low-cost financing for firms investing in on-site renewable energy systems. In this way, electricity price fluctuations will have less impact on companies and, in turn, help protect financial stability.

Akturk, Yeliz; Durmus, Irfan; Kavak, Rasime Pelin; Ozdemir, Meltem
Introduction: This study aimed to investigate the prevalence of aortic valve calcification, aortic dilatation, and coronary artery disease (CAD) in patients with bicuspid aortic valve (BAV) identified incidentally through coronary computed tomography angiography (CCTA) and to compare epicardial adipose tissue (EAT) thickness between BAV and tricuspid aortic valve (TAV) patients. Materials and Methods: Thirty-five BAV patients aged 42-67 and 75 TAV patients aged 31-66 were included in the study. Aortic diameters were measured at the sinus of Valsalva, sinotubular junction, and ascending and descending aorta. Agatston calcium scores and CAD-Reporting and Data System were used to assess coronary artery calcification and atherosclerosis severity. EAT thickness was measured volumetrically, and its relationship with clinical and imaging parameters was evaluated. Results: In patients with BAV, the aortic diameters at the Valsalva sinus, sinotubular junction, and ascending aorta were larger compared to patients with TAV. The difference was statistically significant (P < 0.001). Aortic valve calcification was present in 45.7% of BAV patients, with an average Agatston score of 349.06 +/- 413.22, while no calcification was detected in TAV patients. Although no significant difference in EAT thickness or CAD prevalence was observed between BAV and TAV groups, EAT thickness was positively correlated with aortic dilatation, coronary artery calcification, and aortic valve calcification. Conclusions: BAV patients exhibit distinct vascular and valvular characteristics, with aortic dilatation and aortic valve calcification being prominent. EAT may serve as a marker for these complications. Further prospective studies are needed to elucidate the pathophysiology of BAV and optimize early intervention strategies.

Tokgöz, Cemile; Önal, Aleyna; Üzer, Benian
Both critical algorithm studies and recent scholarship centered on domestication theory emphasize the influence digital platforms have in shaping user behavior while also pointing to the importance of user agency. In their 2019 study, Siles et al. adapted domestication theory to digital platforms through their research on Netflix and developed the concept of mutual domestication. The domestication approach focuses on the shaping effect between everyday life, media technologies, and cultural elements. This study adapts the mutual domestication approach to Spotify as a cultural platform and examines the relationship between user agency and platforms' shaping effect by addressing it as a cyclical process. The study discusses the relationship between algorithm and culture, the transformation of the domestication approach through digital technologies, and the functional as well as algorithmic differences between Netflix, which was examined in the adapted study, and Spotify; it then presents the user-centered research that was conducted. A qualitative research method was adopted, and semi-structured in-depth interviews were chosen as the data collection technique. The sample consists of twenty Spotify users. The data obtained from the interviews conducted with the participants were analyzed descriptively, and the findings were categorized under five themes. In constructing the themes, the study of Siles et al. (2019) was followed; the interview data were interpreted under the themes of personalization, integration, rituals, resistance, and conversion. The research findings show that a dynamic of mutual domestication operates between the platform and the user, and that this process has a much more comprehensive character when compared with the study conducted on Netflix. At the same time, the study reveals that participants evaluate the platform-user relationship through a third actor, the music industry, and that user agency is shaped to a large extent within the framework of the possibilities offered by the platform.

Tas, Muhammed Usame; Usgu, Gunseli
Purpose: This research evaluated the effects of the instrument-assisted soft tissue mobilization (IASTM) technique in individuals with lumbar disc herniation (LDH). Methods: Forty LDH patients were randomly assigned to a control group or an IASTM group (20 patients in each group). The IASTM group underwent a treatment protocol consisting of two IASTM sessions per week in addition to classic physiotherapy methods (hotpack, transcutaneous electrical nerve stimulation, ultrasound and exercise) over a four week period. The treatment specifically targeted the paraspinal muscles, gluteus maximus, gluteus medius and hamstring muscles. All participants were assessed before treatment, immediately after treatment and two months post-treatment using various measures, including pain intensity visual analog scale, straight leg raise (SLR) test, slump test (measuring knee extension from 90 degrees flexion), 6-minute walking test (6-MWT), range of motion (ROM) and the Short Form-36 (SF-36) questionnaire. Results: Both groups experienced a significant decrease in pain immediately after treatment (p=0.002). However, although both groups showed improvements in post-treatment SLR, slump test, 6-MWT, ROM, and SF-36 scores, no significant correlations were found (p=0.208). However, the IASTM group experienced greaterclinical improvement across all parameters. Conclusion: The findings suggest that incorporating IASTM techniques into physiotherapy programs for individuals with LDH can enhance rehabilitation outcomes.

Gezgin, Deniz Mertkan; Erdugan, Fuat; Nurlu, Onur; Kedersiz, Sena; Temel, Ahmet
AIlessphobia in education refers to the anxiety, fear, and feeling of inadequacy that students experience when they are unable to access or use artificial intelligence (AI) tools during academic tasks. AIlessphobia in education, which has been proposed as a relatively new psychological concept in educational settings, may be related to students' self-regulation difficulties and procrastination tendencies. In this context, this study examined the relationship between AIlessphobia in education and academic procrastination in students of the Faculty of Sport Sciences. The study was designed as a cross-sectional study and included 313 undergraduate students selected through convenience sampling. Data were collected using a demographic information form, the AIlessphobia in Education Scale and the Academic Procrastination Scale. Descriptive statistics, Pearson correlation analysis and simple linear regression were used to analyse the data. The findings indicated that AIlessphobia in education and its subdimensions were positively associated with academic procrastination. In the regression model, AIlessphobia in education was significantly associated with academic procrastination and explained 5.2% of the variance. Although the explained variance was small, the findings suggest that higher AIlessphobia in education levels are associated with higher academic procrastination. These findings contribute to the emerging literature on AI-related psychological constructs in education and indicate that academic procrastination may be a significant correlate of AIlessphobia in education among university students.

Kaderi, Sina; Ekinci, Can
Background Closed rhinoplasty techniques are gaining popularity once again as more and more patients demand them. The use of piezoelectric devices (PEDs) is also another popular practice in rhinoplasty surgeries recently to reduce postoperative edema and bruising. Objectives The aim of this study was to propose a new technique in which all osteotomies in closed rhinoplasty surgeries can be performed using PEDs. Methods A comparison was made between 274 patients who underwent closed piezo (CloPi) rhinoplasty and 120 patients who underwent closed rhinoplasty using conventional osteotomy. In the CloPi technique, all osteotomies, including lateral and transverse osteotomies, were performed with PEDs using straight and 90 degrees curved tips. Preoperative and postoperative results obtained with the Rhinoplasty Outcome Evaluation (ROE) questionnaire were compared to evaluate aesthetic and functional results. Results In the CloPi group, the mean age was 30.8 years (range, 18-60 years) and the mean follow-up period was 19.6 months, whereas in the control group, the mean age was 33.5 years (range, 18-61 years) and the mean follow-up period was 29.3 months. Significantly better results were obtained in the ROE questionnaire compared with preoperative values in both groups (P < .001). When comparing the postoperative-preoperative change in ROE scores between the 2 groups, the improvement observed in the CloPi cohort was significantly greater for all items (P < .001), except for Question 2-assessing the ability to breathe-where no significant difference was detected (P = .231). Conclusions CloPi rhinoplasty is an easy and reliable technique in which all osteotomies can be performed with PEDs. Successful surgical results can be achieved with wide surgical dissection.Level of Evidence 3 (Therapeutic)

Merdan, Mehmet; Aydemir, Hilal
PurposeThe purpose of this study is to develop and apply the Elzaki-Homotopy Analysis Method (EHAM) as an efficient analytical technique for solving fractional-order partial differential equations (PDEs). By integrating the Elzaki transformation with the homotopy analysis framework, the study aims to obtain accurate and convergent analytical solutions for nonlinear and random fractional PDEs. Additionally, it seeks to evaluate the influence of stochastic parameters, where coefficients or initial conditions follow various probability distributions. The research further aims to compute the variance, expected value, and confidence intervals of the solutions and visualize the outcomes using MATLAB software.Design/methodology/approachIn this study, the Elzaki-Homotopy Analysis Method (EHAM) is employed by combining the Elzaki transformation with the homotopy analysis method to construct analytical solutions for fractional-order partial differential equations. The local fractional derivative is utilized to handle non-integer order behavior effectively. The proposed approach is applied to both linear and nonlinear equations under random conditions, where initial parameters and coefficients follow uniform, beta, normal, and gamma distributions. Statistical measures such as variance, expected value, and confidence intervals are calculated to analyze solution behavior. All computations and graphical representations are performed using MATLAB (2013a) to verify the method's accuracy and convergence.FindingsThe findings of this study demonstrate that the Elzaki-Homotopy Analysis Method (EHAM) provides highly accurate and rapidly convergent analytical solutions for fractional-order partial differential equations. The method effectively handles both linear and nonlinear problems involving random parameters. Statistical analysis of the obtained solutions reveals that the expected values and variances remain stable across different probability distributions, confirming the robustness of the approach. The convergence region can be easily controlled through the auxiliary parameters of the homotopy method. Comparisons with numerical results validate the reliability and efficiency of EHAM, establishing it as a powerful alternative to conventional numerical and perturbation techniques.Originality/valueThis study presents an innovative analytical framework for solving fractional-order partial differential equations using the Elzaki-Homotopy Analysis Method (EHAM). By integrating the Elzaki transformation with the homotopy analysis approach, the method efficiently addresses the complexities of nonlinear and stochastic systems. The inclusion of random variables with different probability distributions enhances the model's applicability to real-world phenomena. Analytical solutions are systematically derived, and their statistical properties-such as variance, expected value, and confidence intervals-are examined. Implemented through MATLAB (2013a), the results confirm EHAM's strong convergence, reliability, and computational efficiency, positioning it as a superior alternative to traditional numerical techniques.
- MakaleAçık Erişim2026The Anageometric Calculus: Theory, Fundamental Results, and Connections With Classical Analysis
Yalcin, Numan; Dedeturk, Mutlu
In this study, we develop a systematic framework for anageometric calculus as an extension of non-Newtonian analysis. Fundamental concepts, including limits, continuity, differentiation, and higher order derivatives, are established, and the connection to classical calculus is clarified through a logarithmic transformation. Within this framework, we derive the properties of the anageometric derivative, inverse function relations, partial derivatives, and mean value theorems. The theory is extended to integration by establishing the first and second fundamental theorems of anageometric calculus. Furthermore, the structural implications of the anageometric derivative are investigated, demonstrating that the equation D similar to f=lambda f naturally generates power-law solutions rather than classical exponential ones. This highlights the suitability of anageometric analysis for scale-invariant phenomena and proportional growth processes, supported by a practical heat-conduction example.

Aydin, Aydanur
In the event of a natural disaster, women who assume multiple roles within the family unit tend to postpone their health concerns and delay medical appointments. The present study aims to examine the relationship between the level of fear of breast cancer and the implementation of breast cancer preventive behaviours among women following an earthquake. The sample consists of 2,671 women aged 20 and over who participated voluntarily. The data were collected using two instruments: the Breast Cancer Fear Scale and the Women's Breast Cancer Prevention Behaviors Form. Following a comprehensive review of the extant literature, it was determined that women affected by earthquakes exhibited elevated levels of fear of breast cancer. A substantial decline was observed in the utilization of preventive measures necessitating institutional access, including mammography. The findings of this study indicate that education, occupation, and family history of breast cancer have a significant impact on women's post-earthquake fear levels in implementing preventive behaviours. However, given the cross-sectional design and the absence of pre-disaster baseline data, these findings reflect post-earthquake associations rather than temporal or causal trends. Natural disasters can result in the deterioration of health perceptions, exacerbated by heightened stress and health concerns. Consequently, there is an urgent need for innovative approaches to ensure the maintenance of health check-ups and continuous access to preventive care in the aftermath of large-scale natural disasters.

Berktas, Serap
This study aimed to investigate the effects of dietary fibers obtained from cold-pressing by-products on the bioactivity of Spirulina (SP) during in vitro digestion. For this purpose, insoluble dietary fibers (CCDL and KCDL) were extracted from cold-pressing by-products of flaxseed and black cumin. SP was combined with CCDL and KCDL, and subjected to an in vitro digestion protocol (INFOGEST). The results showed that the total phenolic content of SP decreased after oral and gastric digestion with the addition of dietary fiber. After small intestinal digestion, the total phenolic content increased. Antioxidant activity values (DPPH and ABTS) decreased in the presence of dietary fiber, while chlorophyll values increased after small intestinal digestion. In particular, in the presence of CCDL, the chlorophyll content increased from 1.61 mg g(-1) to 4.48 mg 2 g(-1) after small intestinal digestion. Furthermore, the bioactivity values of SP after in vitro digestion varied depending on the type of dietary fiber. While KCDL was effective in increasing phenolic compound content, CCDL was more effective in increasing chlorophyll content. Considering the bioactivity values of SP after oral, gastric, and small intestinal digestion, it was determined that the values increased especially in the small intestine. This highlights the possibility that the bioaccessibility and therefore the bioavailability, of SP can be increased through the incorporation of dietary fiber. The addition of bioactive compounds to the development of functional foods rich in dietary fiber has advantages for the food industry in terms of designing and improving healthy foods. This study emphasizes that the in vitro digestion of Spirulina is regulated in the presence of CCDL and KCDL, and that the addition of dietary fibers may contribute to the potential health benefits of Spirulina.
