    Inhibition Effect of Diosmin Flavanoid on Some Metabolic Enzymes and Investigation of Antioxidant Properties

    Balci, Neslihan

    Diosmin is a natural flavonoid obtained by dehydrating flavanone glycoside hesperidin. This study evaluated the inhibition effects of diosmin flavonoid on human carbonic anhydrases (hCA I and hCA II) and acetylcholinesterase (AChE) enzymes, which are linked to various health issues, and compared the results with standard drugs. The antioxidant potential was assessed using five assays, namely DPPH, ABTS, FRAP, CUPRAC and Fe3+ reducing assays. The results determined that diosmin didn’t exhibit strong antioxidant activity. Additionally, the inhibition effects of diosmin on hCA I, hCA II, and AChE enzymes were examined. It effectively inhibited hCA I and hCA II enzymes with Ki values of 3.84±0.63 nM and 15.64±1.90 nM, respectively (Table 1). For comparison, the Ki values of the standard drug AZA were 1.44 ± 0.32 nM for hCA I and 3.66 ± 0.25 nM for hCA II. On the other hand, diosmin effectively inhibited AChE enzymes with Ki values of 9.31±2.40 nM. The Ki values of the standard drug Tacrine was 6.22±1.95 nM for AChE. These findings suggest that diosmin may serve as a selective enzyme inhibitor, particularly for hCA I, but has limited antioxidant capacity. Diosmin exhibited relatively weak antioxidant activity compared to standard antioxidants.

    Analysis of factors affecting the import demand for wheat and corn in Türkiye using the Seemingly Unrelated Regression Method; [Türkiye’de buğday ve mısır ithalat talebini etkileyen faktörlerin Görünüşte İlişkisiz Regresyon Yöntemine göre analizi]

    Merdan, Kurtuluş; Çomakli, Şafak Ertan

    Objective: In this study, it is aimed to analyze the determining factors on the import demand for wheat and corn, which have an important place in Türkiye's grain imports, with the "Apparently Unrelated Regressions" model. Material and Methods: The data set used in this study consists of annual data covering the years 2006-2021. Stata program was used to analyze the data used in the study. Since Stata or Eviews programs do not provide the Standardized Beta (β) coefficient, statistical analyzes were performed using the formula in Microsoft Excel (β=B*SSXi / SSY). Results: Only the one-year delayed value of wheat imports, which is one of the explanatory variables in the wheat import model, was found to be significant, according to the study's findings. In terms of factors influencing corn import demand, similar results were obtained. Only total corn consumption was found to be statistically noteworthy among the explanatory variables in the corn import model. Conclusion: Based on these findings, wheat imports are influenced by changes in wheat imports from a year ago, while corn imports are influenced by changes in total corn consumption. Based on Türkiye's current structure and the findings obtained, it is understood that the country may continue to maintain its position as an importer of wheat and corn in the future.

    Sol–Gel Synthesized CuFe2O4-Modified Biochar Derived from Tea Waste for Efficient Ni(II) Removal: Adsorption, Regeneration, and ANN Modeling

    Duran, Celal; Ozeken, Sengul Tugba; Seker, Serdal; Ozdes, Duygu

    In the present research, a novel magnetic adsorbent was developed via the sol–gel method by coating CuFe2O4 nanoparticles on biochar sourced from brewed tea waste. The synthesized adsorbent was utilized for the removal of Ni(II) ions from aqueous media. The adsorption efficiency of Ni(II) ions was assessed under crucial experimental conditions such as initial solution pH, contact time, adsorbent dosage, and initial Ni(II) concentration. The adsorbent exhibited rapid adsorption kinetics, achieving equilibrium in approximately 15 min, and maintained high efficiency across a wide pH range. Adsorption experiments were conducted for Ni(II) solutions at their natural pH (5.6) to minimize chemical usage and enhance process simplicity. An impressive maximum adsorption capacity of 232.6 mg g−1 was recorded, outperforming many previously reported adsorbents. Furthermore, desorption studies demonstrated nearly 100% recovery of Ni(II) ions using 1.0 M HCl solution, indicating excellent regeneration potential of the adsorbent. Additionally, the prediction performance of an artificial neural network (ANN) model was evaluated to predict Ni(II) removal efficiency based on experimental variables, showing strong agreement with experimental data. Isotherm and kinetic models were also applied to the data to estimate the adsorption mechanisms. These findings demonstrate the promise of CuFe2O4-modified tea waste biochar for sustainable water treatment applications.

    A Safe and Efficient Brain–Computer Interface Using Moving Object Trajectories and LED-Controlled Activation

    Aydin, Sefa; Melek, Mesut; Gökrem, Levent

    Nowadays, brain–computer interface (BCI) systems are frequently used to connect individuals who have lost their mobility with the outside world. These BCI systems enable individuals to control external devices using brain signals. However, these systems have certain disadvantages for users. This paper proposes a novel approach to minimize the disadvantages of visual stimuli on the eye health of system users in BCI systems employing visual evoked potential (VEP) and P300 methods. The approach employs moving objects with different trajectories instead of visual stimuli. It uses a light-emitting diode (LED) with a frequency of 7 Hz as a condition for the BCI system to be active. The LED is assigned to the system to prevent it from being triggered by any involuntary or independent eye movements of the user. Thus, the system user will be able to use a safe BCI system with a single visual stimulus that blinks on the side without needing to focus on any visual stimulus through moving balls. Data were recorded in two phases: when the LED was on and when the LED was off. The recorded data were processed using a Butterworth filter and the power spectral density (PSD) method. In the first classification phase, which was performed for the system to detect the LED in the background, the highest accuracy rate of 99.57% was achieved with the random forest (RF) classification algorithm. In the second classification phase, which involves classifying moving objects within the proposed approach, the highest accuracy rate of 97.89% and an information transfer rate (ITR) value of 36.75 (bits/min) were achieved using the RF classifier.

    Evaluation of soil-structure resonance by determining local soil conditions in Gümüşhane city center

    Altundaş, Suna; Tanış, Abdulsamed

    Recent earthquakes have adversely affected human life, highlighting the necessity of identifying structural and ground conditions to assess risky areas and mitigate potential damage from future seismic events. Gümüşhane, the designated study area, is susceptible to the impacts of a possible earthquake due to its proximity to the North Anatolian Fault Zone (NAFZ). Accordingly, vertical electrical sounding (VES), multi-channel analysis of surface waves (MASW), and microtremor methods were employed in the central district of Gümüşhane to characterize local ground conditions and to evaluate the resonance hazard potential arising from the interaction between structures and the underlying soil. Dominant period (T0) and frequency (f0), spectral amplification (A0), soil index of vulnerability (Kg), average S wave velocity for 30 m depth (Vs30), ground type, and soil-structure resonance hazard potential were determined. For the study area, f0 values between 1.32–8.91 Hz (T0 values varied between 0.11–0.76 s), A0 values between 0.93–7.63 according to horizontal/vertical spectral ratio (HVSR) analysis, and Vs30 values were between 390–886 m/sec to MASW. As a result of the evaluation of microtremor measurements made in all buildings using the floor spectral ratio (FSR) technique, the soil-structure potential resonance hazard was found to be low. The present study, conducted in Gümüşhane, examined the subject of soil-structure interaction. In the process of planning new residential areas, it is imperative to ensure the reliability of construction based on the local ground conditions. Furthermore, it is essential to determine the risk status of buildings in relation to potential earthquake movements.

    Disease Burden and Sexual Life in Patients with Fibromyalgia: A Phenomenological Study

    Demir Çam, Sevgi; Uzun, Sevda; Koyunoğlu, Bedriye Cansu

    The aim of this study was to evaluate the burden of disease and sexual life experiences in patients with fibromyalgia using a phenomenological approach. In the study using phenomenological research method, semi-structured in- depth interviews were conducted with 20 fibromyalgia patients who applied to the neurology outpatient clinic of a state hospital in a province in southern Turkey. Criterion sampling method, one of the purposive sampling methods, was used to reach the sample group. Interviews continued until data saturation was achieved. All interviews were recorded on a voice recorder after obtaining the necessary permissions from the patients and then transcribed. The data of the study were evaluated using thematic analysis. The study was conducted and reported according to the COREQ checklist. Data analysis revealed two main themes (effects of the disease and sexual problems and coping) and five sub-themes (mental, physical, social, problems and coping). As a result of the study, it was determined that the patients experienced serious physical, mental and social problems due to and their sexual life was also negatively affected. Individuals experience significant problems related to sexual life due to fibromyalgia. Since fibromyalgia is a multifaceted disease, professional evaluation of sexual life in patients and diagnosis of sexual dysfunctions are of great importance in terms of improving quality of life.

    New Numerical Solutions for Caputo–Fabrizio Fractional Differential Multidimensional Diffusion Problems

    Şahin, Yasin; Merdan, Mehmet

    This study examined the multidimensional fractional diffusion equations that characterize the density dynamics in a diffusing medium utilizing the exact and analytical Aboodh transform decomposition method (ATDM). The Caputo–Fabrizio (CF) derivative is utilized to account for the fractional derivative that is being employed here. The suggested method handles nonlinear terms by combining the Adomian decomposition method (ADM) with the Aboodh transform (AT) and Adomian polynomials. Since the AT can only be applied to linear equations, ADM is a helpful technique for estimating solutions to nonlinear differential equations. In nonlinear systems, multidimensional diffusion problems which account for the production of stripes in two-dimensional systems are important. Additionally, we used MATLAB to compute numerical and graphical data that illustrate how the close-form analytical solution compares to the precise solution. Promising and appropriate for addressing multidimensional diffusion problems with fractional derivatives are the obtained results. The key benefit is that our devised approach does not depend on presumptions or constraints on variables that skew the actual issue. Overcoming fluctuating constraints that can make it difficult to discover the answer and represent the problem depends much on this technique. In the domains of science and technology, the approach presented in this work offers exceptional computational accuracy and convenience of use for analyzing and resolving intricate phenomena associated with CF fractional nonlinear partial differential equations.

    Multi-sensor data fusion based on the similarity measure and belief (Deng) entropy under neutrosophic evidence sets

    Köseoğlu, Ali; Şahin, Rıdvan; Demir, Ümit

    The Dempster–Shafer evidence theory is a very practical concept for handling uncertain information. The foundation of this theory lies in the basic probability assignment (BPA), which exclusively accounts for the degree of support attributed to focal elements (FEs). In this study, neutrosophic evidence sets (NESs) are defined to introduce additional probabilistic measures, aimed at addressing the uncertainty, imprecision, incompleteness, and inconsistency present in real-world information. The basic element of NESs is a neutrosophic basic probability assignment (NBPA), which consists of three components. The truth degree of FEs is represented by the first BPA, the second BPA represents the indeterminacy degree of FEs, and the last BPA characterizes the falsity degree of FEs. In NESs, each support degree of FEs is shown separately without any limitation. Therefore, the general concept of NESs is broader compared to traditional evidence sets and intuitionistic fuzzy evidence sets. Unlike the neutrosophic set (NS), the NBPA method assigns truth-support, uncertainty-support, and false-support degrees, as well as these support degrees, to single and multiple subsets in a discriminative framework. This paper aimed to develop some information measures for NESs, such as neutrosophic Deng entropy (NDE), neutrosophic cosine similarity measure, and neutrosophic Jousselme distance. Then, an improved method based on NDE and neutrosophic cosine similarity measure was established to combine contradictory evidence to increase the influence of reliable evidence on the one hand and to reduce the influence of unreliable evidence on the other hand. Finally, a case involving sensor data integration for target identification was studied to highlight the importance of these innovative ideas. The numerical example demonstrates that the proposed method provides more reliable and superior fusion performance compared to classical models, particularly in scenarios involving high conflict and uncertain information. However, the effectiveness of the method is partially influenced by the structure of the similarity matrix and the entropy parameters, which necessitates careful parameter tuning to achieve optimal results. These limitations are explicitly highlighted to serve as a guide for future improvements and broader applications of the method.

    The interaction between the Mediterranean diet, obesity, and disease severity: A case–control study on psoriatic patients

    Konyalıgil Öztürk, Nurefşan; Kurtbeyoğlu, Emine; Atuk Kahraman, Tutku; Çiçek, Betül; Çınar, Salih Levent; Borlu, Murat

    Background: Psoriasis is a chronic inflammatory disease that can be influenced by nutritional status and dietary habits. In particular, adherence to the Mediterranean diet, known for its anti-inflammatory properties, is increasingly being investigated in relation to disease severity and nutritional status. Aims: This case–control study, including 50 psoriatic patients and 40 healthy controls, aimed to examine the correlation between adherence to the Mediterranean diet and disease severity, nutritional status, and disease presence in patients with psoriasis. Methods: The clinical severity of psoriasis was assessed using the Psoriasis Area and Severity Index (PASI) score. Anthropometric measurements were taken, and body composition was determined using bioelectrical impedance analysis. All participants’ Mediterranean Diet Adherence Screener (PREDIMED) scores and 24-h food consumption records were evaluated. Results: The body weight (BW), waist circumference (WC), hip circumference (HC), and fat mass (FM) values of psoriatic patients were found to be significantly higher than those of the healthy control group (p < 0.05). The PREDIMED score of psoriatic patients was found to be significantly lower than that of the control group (p < 0.001). A negative correlation was observed between the PREDIMED score and BW, FM, and HC (p < 0.05). PASI levels decreased as PREDIMED scores increased (r = −0.314, p = 0.048). According to logistic regression analysis, after adjusting for age and sex, the likelihood of being healthy was approximately 6.363 times higher in those with high adherence to the Mediterranean diet (p < 0.001). Conclusion: When psoriatic patients were compared with healthy controls, significant differences were observed in PREDIMED scores. Notably, greater adherence to the Mediterranean diet was associated with reduced disease severity, suggesting a potential mitigating effect even in the presence of obesity.

    Background: Nurses are among the most interactive professionals in society, providing both care and psychosocial and psychotherapeutic interventions for individuals with mental health issues. Nurse-centred approaches have demonstrated a positive impact on addressing mental health issues. Aim: This study aimed to evaluate the effectiveness of psychosocial and psychotherapeutic interventions administered by nurses in managing mental health issues. Methods: For this meta-analysis, data were gathered through a comprehensive search of databases, including PubMed, Web of Science, EBSCOhost, Google Scholar and the YÖK Thesis Center, with no restrictions on publication year. Following the review process, a total of 25 studies were included in the analysis. The PRISMA checklist was employed to guide our study. Results: The meta-analysis revealed that interventions implemented by nurses in the context of mental health were effective. Specifically, the psychosocial and psychotherapeutic interventions significantly reduced depression levels in individuals (SMD: −0.918, 95% CI: −1.350 to −0.486; Z = −4.161; p < 0.05) and anxiety levels (SMD: −0.61, 95% CI: −1.190 to −0.029; Z = −2.59; p < 0.05). Additionally, these interventions were associated with an improvement in individuals' quality of life (SMD: 0.673, 95% CI: 0.303–1.403; Z = 3.56; p < 0.05). Conclusion: Nurses can play a pivotal role in addressing mental health issues, effectively contributing to the reduction of anxiety and depression levels while enhancing the overall quality of life for individuals.

    Analyzing the October 16, 2024 MW 5.9 Kale (Malatya) earthquake in relation to the February 2023 Kahramanmaraş earthquake sequence and local tectonic dynamics

    Senkaya, Mustafa; Alkan, Hamdi; Öztürk, Serkan; Büyüksaraç, Aydın

    The 6 February 2023 Mw 7.7–7.6 Kahramanmaraş earthquake sequence has significantly impacted the East Anatolian Fault zone, including the city of Malatya and its immediate surroundings. In addition to the aftershocks of February 2023, the Mw 5.9 Kale earthquake that occurred on October 16, 2024, further underscores the ongoing seismic activity in the region. This study analyzes the distribution of b-values derived from a comprehensive dataset comprising 14,549 earthquakes and the Coulomb stress variations associated with the aftershocks of the February 2023 sequence and the Kale earthquake. The primary objective of this analysis is to enhance the understanding of the tectonic setting that contributed to the occurrence of the Kale earthquake. The findings indicate that the low b-values and stress transfer through the Pütürge segment toward the unnamed fault near Kale are significant contributing factors to the occurrence of the Kale earthquake. Additionally, positive stress variations from Doğanşehir to Malatya’s city center suggest a potential fault oriented toward the city center that may increase the current earthquake hazard. Furthermore, the distribution of seismic events around Malatya suggests a possible barrier supported by previous magnetic data analysis between Malatya and Kale. Lastly, the observed stress variations for the Kale earthquake indicate the likelihood of upcoming seismic events in both the northeast and southwest directions of the Kale.

    Introduction The growing number of people living with, through and beyond cancer poses a new challenge for sustainable survivorship care solutions. Digital health solutions which incorporate various information and communication technologies are reshaping healthcare; offering huge potential to facilitate health promotion, support healthcare efficiencies, improve access to healthcare and positively impact health outcomes. Digital health solutions include websites and mobile applications, health information technologies, telehealth solutions, wearable devices, AI-supported chatbots and other technologically assisted provision of health information, communication and services. The breadth and scope of digital health solutions necessitate a synthesis of evidence on their use in supportive care in cancer. This umbrella review will identify, synthesise, and compare systematic reviews which have evaluated the efficacy or effectiveness of digital solutions for adult cancer survivorship care with a particular focus on surveillance and management of physical effects, psychosocial effects, new cancer/ recurring cancers and supporting health promotion and disease prevention.Methods and analysis An umbrella review of published systematic reviews will be undertaken to explore the types of digital health solutions used, their efficacy or effectiveness as a form of supportive care, and the barriers and enablers associated with their implementation. The umbrella review will be reported according to the Preferred Reporting Items for Overviews of Reviews (PRIOR) checklist. A search will be conducted across key databases. Records will be assessed independently by two review authors for eligibility against predefined criteria and will undergo two stage title, abstract and full text screening. All systematic reviews that meet the inclusion criteria will be assessed for quality using the AMSTAR 2 checklist with quality assessment and data extraction by two reviewers. The degree of publication overlap of primary studies across the included reviews will also be calculated and a mapping of the evidence will also be presented.Ethics and dissemination As this research proposes using systematic reviews that are already published, ethical approval is not required. Results from this umbrella review will be published in a peer-reviewed journal where any significant deviations from the protocol will be justified.

    Revealing the environmental influences of energy, transport, and pollution taxes on different transportation modes

    Artan, Seyfettin; Pata, Ugur Korkut; Hayaloglu, Pinar; Cakir, Mehmet Ali; Recepoglu, Mursit; Cay Cakir, Sumeyra

    The need for transportation is increasing with the effect of globalization in the developing economic system. The transportation sector, which is essential for economic development, may pose some threats to a sustainable environment. Although European countries have achieved various successes in reducing carbon emissions, they are struggling to reduce carbon dioxide (CO2) emissions from transportation. To overcome this difficulty, European countries are using various policy instruments such as environmental taxes. In this context, this study investigated the impact of disaggregated environmental taxes (pollution, energy, and transport), structural change, and institutional quality on transport-related carbon emissions (water, air, and road transport) in 24 European countries over the period 2008-2022. To this end, the study uses the novel half-panel jackknife estimation and the bias-corrected method of moments. The results indicate that there is no long-term relationship between environmental taxes and water transportation-related CO2 emissions. In contrast, structural changes and pollution taxes are effective in reducing road and air transport-related CO2 emissions. These results suggest that European countries should focus on reducing CO2 emissions through effective pollution taxes and encourage carbon taxes instead of energy and transport taxes, thereby supporting the European Green Deal's goal of becoming the first climate-neutral continent.

    Compositional variability and alteration dynamics of chromitites under greenschist metamorphism in the Kizildag ophiolite, southern Turkiye

    Akmaz, Recep Melih; Uysal, Ibrahim; Su, Ben-Xun; Sen, Ahmet D.; Hu, Wen-Jun; Seitz, Hans-Michael; Mueller, Dirk; Eslami, Alireza

    This study presents a complete alteration sequence in chromitites from the Kizildag ophiolite (southern T & uuml;rkiye), documenting three distinct chromite types that record processes related to Neotethyan subduction. Chromitites exhibit predominantly lenticular forms and occasionally banded textures, embedded within mantle peridotites and the mantle-crust transition zone, specifically harzburgite and dunite. Our analysis categorizes chromite grains into three groups: fresh, altered, and porous. Fresh chromites are characterized by high contents of Cr2O3 ranging from 42.69 to 57.08 wt% and Al2O3 from 12.46 to 25.34 wt%. In contrast, altered chromites, typically located along fractures or at the edges of fresh grains, show significant variability in chemical composition, with Cr2O3 content between 43.34 and 63.94 wt% and Al2O3 between 2.91 and 14.84 wt%. Porous chromites, distinguished by their porous structure, present Cr2O3 contents from 44.58 to 52.66 wt% and Al2O3 from 3.00 to 8.38 wt%. Notably, altered and porous chromites demonstrate substantial enrichments in Fe and trace elements such as Mn, Ni, Zn, Co, and Ga, indicating a shift due to metamorphic processes. The observed high Cr# (0.68-0.93) and low Mg# (0.25-0.65) values in rims of the altered and porous chromite further illustrate the metamorphic influence on chromite, with greenschist-facies conditions indicated by the Cr-Al-Fe3+ diagram at temperatures below 450 degrees C. The alteration dynamics reflect a progression that initiates with the olivine matrix and advances through reactions involving fresh chromites. This progression results in mass loss, the formation of chlorite, and the porous structures. Our findings contribute to the understanding of metamorphic alteration processes in chromitites and provide a detailed account of the geochemical trends (such as Fe/Mg exchange and trace element enrichment) that reflect greenschist-facies metamorphism. The evidence of chlorite formation and the prevalence of porous textures highlight the influence of metamorphic fluids over serpentinization, offering a model for chromite alteration in supra-subduction zones. This research elucidates the metamorphic history of chromitites in the Kizildag ophiolite.

    Low Serum and Urine Fetuin-A Levels and High Composite Dietary Antioxidant Index as Risk Factors for Kidney Stone Formation

    Icer, Mehmet Arif; Koçak, Tevfik; Icer, Yusuf; Kocyigit, Emine; Agagündüz, Duygu; Gezmen-Karadag, Makbule; Yesil, Suleyman; Budán, Ferenc

    Background: Fetuin-A prevents the precipitation of hydroxyapatite in supersaturated solutions of calcium and phosphate; however, its relationship with nephrolithiasis has yet to be clarified. The aim of this study was to investigate the protective and predictive roles of serum and urine fetuin-A levels in nephrolithiasis and their relationships with the composite dietary antioxidant index (CDAI). Methods: This study involved 75 adult patients with kidney stone disease and 71 healthy adults without kidney stone disease in the control group. Participants had specific anthropometric measurements taken, and three-day food records were kept. The CDAI was calculated by summing six standard antioxidants, including vitamins A, C, and E, manganese, selenium, and zinc, representing participants' antioxidant profile. In addition to some analyzed serum and urine parameters of the participants, fetuin-A levels were measured using the enzyme-linked immunosorbent assay (ELISA) method. Results: In patients with kidney stones, both serum and urine fetuin-A levels (676.3 +/- 160.14 ng/mL; 166.6 +/- 128.13 ng/mL, respectively) were lower than in the control group (1455.6 +/- 420.52 ng/mL; 2267.5 +/- 1536.78 ng/mL, respectively) (p < 0.00001). In contrast, the CDAI was higher in patients with kidney stones compared to those without kidney stones (p < 0.001). Besides, several dietary parameters had significant positive correlations with serum and/or urinary fetuin-A. Conclusions: The present study suggests that serum and urinary fetuin-A levels may serve as protective factors against kidney stones and could potentially be used as predictive markers for the development of nephrolithiasis. Furthermore, our results suggest that the CDAI above a certain level may increase the risk of stone formation and that some dietary parameters may affect the levels of this biomarker in serum and urine.

    Crackers are popular bakery products known for their crunchy texture and long shelf life. Typically made from leavened or unleavened dough with wheat flour, oil, water, and additives, crackers have undergone recipe enhancements to improve sensory and nutritional profiles. While many studies explore cracker and biscuit formulations, fruit seed oils remain underexplored. Fruit seeds, often discarded as waste, are rich in essential fatty acids, amino acids, and micronutrients. Oils from seeds such as grape, pomegranate, rosehip, and apricot have gained attention for their health benefits, which presents an opportunity for innovation in bakery products. This study evaluated the potential of incorporating various fruit seed oils (pomegranate, apricot kernel, grape, fig, and rosehip) into cracker formulations. Crackers were assessed for physicochemical properties, antioxidant activity, mineral content, texture, and sensory attributes, with sunflower oil as the control. Results showed that the addition of fruit seed oils significantly influenced cracker properties. Crackers with apricot kernel oil had the highest ash content (2.29 +/- 0.13%) and exhibited a more acidic character, as did those with grape seed oil. Moisture content decreased significantly when rosehip seed oil was used (P < 0.05). Grape seed oil yielded the highest water-holding capacity, while sunflower oil provided the highest oil-holding capacity. Crackers made with rosehip and apricot kernel oils demonstrated improved antioxidant properties. Using fruit seed oils not only enhances nutritional value (e.g. vitamins, minerals, antioxidants, and dietary fiber) but also reduces material waste, contributing to sustainability and better resource utilization.

    The selection of transport policies by countries is critical both for international relations and for the implementation of effective and sustainable transport practices. Countries consider numerous parameters when deciding on transport policies. This study aims to develop a Decision Support System (DSS) to assist countries in selecting transport policies and to demonstrate its applicability. The primary motivation of the research is to identify transport policies for Russia's Arctic region and to determine the best alternative policy based on expert evaluations. For this purpose, the IF-SIWEC-ARLON (Intuitionistic Fuzzy Sets - Simple Weight Calculation - Alternative Ranking Using Two-Step Logarithmic Normalization) hybrid method was developed as a DSS in this study. To implement this hybrid method, a decision model incorporating experts, criteria, and transport policies was first established. The contribution levels of experts to the decision-making process were calculated using IF sets. Next, the criteria weights were determined using the IF-SIWEC approach. Finally, the ranking of transport policies was carried out using the IF-ARLON method. An algorithm representing the application of this hybrid method was developed and applied to a case study focusing on Russia's transport policy selection process of Northern Sea Route (NSR) in the Arctic region. The results supported the successful application of the IF-SIWEC-ARLON hybrid method. Its robustness was tested through sensitivity analysis scenarios, while the consistency of the findings was verified via comparative analyses. The study concluded that the best transport policy for Russia's Arctic region is Improved regulatory control with strategic international partnerships, with the most influential criterion in the decision process identified as State interests, security, and sovereignty..
