In this article, the 1st and 6th paragraphs in the “Discussion” section contain several errors. The corrected paragraphs are given below. This study aimed to assess the spiritual well-being levels and spiritual care needs of individuals diagnosed with lung cancer. The findings revealed that the patients exhibited high spiritual well-being levels, with the “harmony with nature” sub dimension scoring particularly high in relation to spiritual well-being. This aligns with several studies which reported high spiritual well-being of cancer patients (Martins et al., 2020; Rabow & Knish, 2015).” The study identified high spiritual needs among the patients, with the specific subdimension “informing them about their health” obtaining the highest scores. Notably, in the current study, it was observed that patients’ needs in terms of “informing them about their health” increased, deviating from the emphasis on love, support, and bonding seen in other studies (Kırca et al., 2023; Shi et al., 2023). This divergence is thought to be linked to differences in the disease stage. The original article has been corrected.

AtıfWoS3İncele - MakaleAçık Erişim2024Scopus SJRQ2A new method of smoothness-constrained magnetotelluric modelling with the utility of Pareto-optimal multi-objective particle swarm optimization
Büyük, Ersin
Particle swarm optimization, one of the modern global optimization methods, is attracting widespread interest because it overcomes the difficulties of conventional inversion techniques, such as trapping at a local minimum and/or initial model dependence. The main characteristic of particle swarm optimization is the large search space of parameters, which in a sense allows the exploration of the entire objective function space if the input parameters are properly chosen. However, in the case of a high-dimensional model space, the numerical instability of the solution may increase and lead to unrealistic models and misinterpretations due to the sampling problem of particle swarm optimization. Therefore, smoothness-constrained regularization techniques used for the objective function or model reduction techniques are required to stabilize the solution. However, weighting and combining objective function terms is partly a subjective process, as the regularization parameter is generally chosen based on some kind of criteria of how the smoothing constraints affect the data misfits. This means that it cannot be completely predefined but needs to be adjusted during the inversion process, which begins with the response of an initial model. In this paper, a new modelling approach is proposed to obtain a smoothness-constrained model from magnetotelluric data utilizing multi-objective particle swarm optimization based on the Pareto optimality approach without using a regularization parameter and combining several objective function terms. The presented approach was verified on synthetic models and an application with field data set from the Çanakkale–Tuzla geothermal field in Turkey. Findings from these analyses confirm the usefulness of the method as a new approach for all constrained inversions of geophysical data without the need to combine the objective function terms weighted by a regularization parameter.

Aktaş, Haktan; Meral Aktaş, Hacer; Ürkek, Bayram; Şengül, Mustafa; Çetin, Bülent
Kefir, which has many beneficial effects on health, is one of the most consumed fermented milk products worldwide. It is important to increase consumption of the fermented product for public health. In this study, it was aimed to increase the beneficial effects of kefir on public health. Therefore, kefirs produced from different types of milk (cow, buffalo, sheep, and goat) were concentrated, and obtained spreadable kefir samples were investigated in terms of their microbiological characteristic (lactic bacilli, lactic cocci, yeasts and moulds, total bacteria, and coliform bacteria), benzoic acid content, physicochemical properties (fat, total solid, ash content, acidity, pH, syneresis, viscosity, colour, and rheological properties), and sensory characteristic. It was determined that APC, lactic bacilli, lactic cocci, and yeast counts of the concentrated kefir samples changed between 6.90 and 8.64, 6.89 and 8.61, 7.42 and 8.72, and 2.17 and 5.39 log CFU/g, respectively, during storage. Mould and coliform bacteria were not detected in the samples. The concentrated kefir samples contained benzoic acid in the range of 18.30–119.58 mg/L. Results from this study showed that type of milk caused differences on APC, lactic bacilli, lactic cocci and yeast count, total solids, ash, fat, acidity, pH, syneresis, colour, viscosity and rheological parameters, and benzoic acid content. In addition, milk type affected sensory properties of the kefirs. Concentrated kefirs produced from cow and buffalo milk were the most liked by panellists. Finally, it was determined that concentrated kefir was favoured as a new product by most of the panellists.

Eyuboglu, Ekrem; Hasirci Tugcu, Zeynep; Kuzulugil, Kenan; Cavdar, Ismail Hakki
The need for reliable and uninterrupted communication systems in the marine environment has become critically important with increasing maritime activities, environmental monitoring, and the spread of autonomous systems. However, the complex structure of electromagnetic wave propagation in a sea environment limits the accuracy of the existing propagation models. Thus, the Modified Round Earth Loss (REL) model was first developed in this study to estimate the path loss more accurately in shore-to-ship communication. Subsequently, a piecewise modeling approach based on the principle of two-segment data modeling was proposed. In the Modified REL model, unlike the traditional REL model, the paths and gains of the direct and reflected waves were not considered equal in the calculations. Moreover, unlike in the classical approach, the receiver height was not taken as a fixed value; the estimated best receiver height value for each measurement was included in the calculations as a representation of the effect of roughness in the sea environment. Thus, the model is better adapted to various environmental conditions. In addition, the proposed piecewise model divides the propagation medium into two regions using a break point calculated by Fresnel zone theory. The Modified REL model was used for the first region and the log-distance model was used for the second region. This method allows for more accurate modeling of signal behaviors, especially at different distances. Experimental measurements and performance evaluations conducted using four different shore-to-ship communication scenarios show that the Modified REL model shows an average improvement of up to 3% in Root Mean Square Error (RMSE) values compared to the classical REL model. Additionally, the proposed piecewise model improves the fitting error of the Modified REL model, which models the data as a single whole, by an average of 22.25%. These findings emphasize the necessity of propagation models that are sensitive and adaptable to environmental changes for maritime communication.

Sipahi, Ferkan; Zeybek, Halil İbrahim; Gücer, Mehmet Ali; Işık, Fatih
The carbonate rocks in the eastern part of NE Turkey are situated within the Pontide paleo-magmatic arc and are frequently in contact with granitoid formations, often hosting skarn mineralization in the region. These carbonate rocks, typically found on ridges and hillsides exhibit predominant orientations along east–west, northeast-southwest, and northwest-southeast directions. A part of limestone, named as biomicrite, metamorphosed and display a saccharoidal texture. Comprised mainly of calcite, with less secondary quartz and iron oxide minerals, these carbonate rocks are classified as Fe-poor calcio-carbonate and magnesio-carbonate, having higher CaO and LOI contents. Marble and recrystallized limestone with granoblastic texture mainly comprise of calcite, less quartz, magnetite, and hematite. Marble classification diagrams suggest calcic skarn mineralization, indicated by decreasing CaO (or CO2) and increasing MgO from limestone to marble (or skarn). Strontium contents deviate slightly from the lithosphere carbonate average, while low Rb contents, attributed to skarn metamorphism, indicate the absence of K-bearing minerals. The high Al2O3/SiO2 in the carbonate rocks can points out hydrothermal activity and carbonate disengagement can indicate to actualize at temperatures that can affect Ce and Al mobilities. The low authigenic U value, low U/Th and Ni/Co ratios in carbonate rocks have been implied that protolith constituents deposited under oxic conditions. Positive Eu anomalies in limestone and marble suggest the influence of hydrothermal fluids. Carbon and oxygen isotope values in marble are similar with those of metamorphic and skarn marbles, indicating a magmatic origin. Overall, mineralogical and geochemical analyses propose a uniform source and/or geological process for all studied marbles.

Recent studies have focused on Anthemis sp. because of their rich chemical composition and application in the treatment of diseases associated with inflammation. The purpose of this study was to determine the active chemicals responsible for the anti-inflammatory properties of Anthemis cotula, A. tomentosa, A. austriaca, and A. tinctoria var. tinctoria. Therefore, the 5-Lipoxygenase (5-LOX) was used to assess the anti-inflammatory properties of methanol extracts that were extracted from the aerial parts of the mentioned species, with an IC50 value of 23.88 μg/mL, the methanol extract of A. tinctoria var. tinctoria demonstrated anti-inflammatory effects close to the standard (Indomethacin, IC50: 18.05 μg/mL). Compared to the other extracts, the methanol extract of A. tinctoria var. tinctoria demonstrated significantly greater anti-inflammatory activity. A. tinctoria var. tinctoria and A. tomentosa methanol extracts, which were the most active in comparison to other extracts, were fractionated using the bioactivity-guided fractionation method. Their anti-inflammatory properties were evaluated to determine the compounds responsible for the activity. With an IC50 value of 3.44 μg/mL, the ethyl acetate fraction of A. tinctoria var. tinctoria (ATiEA) was found to be the most active of all the fractions. After ATiEA was further fractionated using column chromatography, it was found that ATiEA-II, one of its sub-fractions, was more effective than other sub-fractions against the 5-LOX, with an IC50 value of 2.93 μg/mL. Furthermore, the sub-fractions' total phenol and flavonoid contents were examined to confirm their anti-inflammatory properties. The sub-fraction ATiEA-II exhibited higher total flavonoid content (743,86 μg QE/g dry weight) and total phenol content (4659.36 μg GA/g dry weight) than other sub-fractions, which was in line with its anti-inflammatory activity. GC/MS and LC-MS/MS were used to clarify the effective compounds of the sub-fraction ATiEA-II. Experiments on the anti-inflammatory properties of different Anthemis sp. have demonstrated the good anti-inflammatory potential of this species. Specifically, ATiEA-II, a sub-fraction of A. tinctoria var. tinctoria, may contain a novel anti-inflammatory drug molecule.

Şengül, Süleyman; Bekiryazici, Zafer; Merdan, Mehmet
In this study, the optimal q-Homotopy Analysis Method (optimal q-HAM) has been used to investigate fractional Abel differential equations. This article is designed as a case study, where several forms of Abel equations, containing Bernoulli and Riccati equations, are given with ordinary derivatives and fractional derivatives in the Caputo sense to present the application of the method. The optimal q-HAM is an improved version of the Homotopy Analysis Method (HAM) and its modification q-HAM and focuses on finding the optimal value of the convergence parameters for a better approximation. Numerical applications are given where optimal values of the convergence control parameters are found. Additionally, the correspondence of the approximate solutions obtained for these optimal values and the exact or numerical solutions are shown with figures and tables. The results show that the optimal q-HAM improves the convergence of the approximate solutions obtained with the q-HAM. Approximate solutions obtained with the fractional Differential Transform Method, q-HAM and predictor–corrector method are also used to highlight the superiority of the optimal q-HAM. Analysis of the results from various methods points out that optimal q-HAM is a strong tool for the analysis of the approximate analytical solution in Abel-type differential equations. This approach can be used to analyze other fractional differential equations arising in mathematical investigations.

Erol, Ismail; Peker, Iskender; Benli, Tolga; Ar, Ilker Murat; Searcy, Cory
A solar photovoltaic energy supply chain (SPvESC) is a global network with several linkages, including mineral and metal mining, material processing, and module and panel manufacturing. Due to the wide range of uncertainties and the unfavorable environmental effects associated with current linear business models, this global network is vulnerable to disruptions. Strengthening the resilience of SPvESCs is crucial for addressing any disturbances. This requires identifying the key enablers of resilience in SPvESCs, an area that has been understudied in the existing literature. An enabler is an aspect that facilitates the achievement of a goal by another aspect. This research contributes to the existing literature by systematically investigating the enablers for SPvESCs to achieve resilience. Thus, the objective of this analysis is to identify enablers that have the potential to enhance the resilience of SPvESCs in Türkiye. This was done by applying the Nominal Group Technique (NGT) in conjunction with a review of the current literature. Neutrosophic (N)-DEMATEL was then utilized to determine the relationships between the identified enablers. Finally, the results were validated using N-DELPHI. The results revealed that sensing and seizing new business models, adaptability to changes in novel energy generation and information technologies, and business contingency plans for natural and man-made disasters were the most influential enablers. The findings provide implications for practitioners, policymakers, and researchers to help ensure improved resilience in SPvESCs.

Kobya, H.N.; Baltaci, C.; Karpuz, O.
Honey vinegar is little known in Turkey, while pollen- or propolis-added honey vinegar is yet to be found. Therefore, the objectives of the present work were to produce chestnut honey vinegar enriched with pollen and propolis, and to analyse their physicochemical compositions, mineral contents, colours, and antioxidant activities. Eleven different honey vinegars were produced using various methods. There were significant increases in the total antioxidant activity of both pollen- and propolis-enriched vinegars, with 73 and 56% increases, respectively, compared to plain honey vinegar, and these increases were more than twice that of grape vinegar. The ferric-reducing activity and phenolic content of vinegar enriched with propolis increased by 43 and 52%, respectively, compared to plain honey vinegar, and more than threefold compared to grape vinegar. Principal component analysis revealed a strong positive correlation among all antioxidant tests and the most significant components, including antioxidant capacity, total phenolic content, and total flavonoid content. The colour difference was determined as follows: 5 < total colour difference (∆E*ab). All vinegar samples exhibited highly variable physicochemical properties. High amounts of Na, K, Mg, and Ca were also detected. Vinegar samples containing pollen and propolis are suitable under the Turkish Food Codex legislation. The findings of the present work would encourage the production of honey vinegar enriched with pollen and propolis, as well as increase attention to honey vinegar.

Background: This in vivo study evaluated the effect of graphene oxide and graphite coatings, coupled with the micro-arc oxidation (MAO) surface roughening technique, known for their mechanical strength, chemical stability, and antibacterial properties. The main objective was to assess the degree of improvement in osseointegration of titanium implants resulting from these interventions. Materials and methods: In this study, 32 female rats were utilized and randomly allocated into four groups (n = 8 each): machined surface titanium implants (control), those roughened by the MAO method, those coated with graphene oxide-doped MAO, and those with a graphite-doped MAO coating. Titanium implants were surgically placed in the right tibia of the rats. Rats undergoing no additional procedures during the 4-week experimental period were sacrificed at the end. Then, the implants and surrounding bone tissues were separated and embedded in acrylic blocks for reverse torque analysis. Using a digital torque device, the rotational force was applied to all samples using a hex driver and racquet until implant separation from the bone occurred, with the corresponding values recorded on the digital display. Then, statistical analysis was performed to analyze the data. Results: No statistically significant difference between the groups was observed in the biomechanical bone–implant connection levels (N/cm) (P = 0.268). Post-hoc tests were not required because no discernible differences were identified between the groups. Conclusion: Within the scope of this study, implants treated with the MAO method, along with those coated with graphene oxide- and graphite-doped MAO method, did not exhibit significant superiority in terms of osseointegration compared to machined surface titanium implants.

To study the influence of nickel addition on the microstructure, mechanical and lubricated wear properties of Zn-40Al-2Cu alloy, one ternary and five quaternary Zn-40Al-2Cu-(0.5-2.5)Ni alloys were made by permanent mold casting. The wear behavior of these alloys was studied using a block-on-cylinder type test machine, after examining their microstructural and mechanical features. The microstructure of Zn-40Al-2Cu alloy was comprised of aluminum-rich α dendrites and a eutectoid α+η phase mixture. The addition of nickel caused the formation of intermetallic Al3Ni particles in the microstructure of this alloy. As the nickel content of alloys increased their hardness, friction coefficient, working temperature, and average surface roughness increased to certain extents but their strength, ductility, impact resistance, and wear volume decreased. However, the values of their wear volume and average surface roughness exhibited opposite changes with increasing nickel content. The worn surfaces of Zn-40Al-2Cu-Ni alloys were observed to be characterized by smearing and scratching marks. Furthermore, the wear and mechanical properties of these alloys were correlated, and the results were discussed in terms of their microstructural features. Finally, it may be concluded that the nickel addition adversely affects the ductility of Zn-40Al-2Cu alloy but increases its wear resistance.

In this study, the physicochemical properties, antioxidant capacity, sensory properties, and phenolic and mineral profiles of instant rosehip teas prepared using spray-drying (SD) and freeze-drying (FD) were compared. The yield of instant tea produced using FD and SD was 23.75 and 21.25 g/100 g, respectively. The total color difference between the FD and SD tea was 50.74, with the SD sample exhibiting higher redness and yellowness. The FD tea was richer in ascorbic acid than SD tea (67.2 and 59.4 mg/100 g dry weight, DW, respectively). The mineral content ranged from 0.20 mg/kg DW (copper) to 2,837 mg/kg DW (potassium) in SD tea, and from 0.31 mg/kg DW (copper) to 3,083 mg/kg DW (potassium) in FD samples. The total phenolic content was 1,315 and 1,495 mg GAE/100 g DW of SD and FD samples, respectively. The antioxidant capacity of instant rosehip teas was determined as total antioxidant capacity, ferric reducing antioxidant power and DPPH radical scavenging activity. In all these assays, FD tea was found to have a higher antioxidant capacity. In the phenolic profile determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique, protocatechuic acid dominated in instant rosehip teas prepared using both methods. The main flavonoids identified were quercetin, quercitrin, hyperoside and luteolin 7-glucoside. Following the sensory analysis, the panelists have generally preferred the FD tea in terms of aroma and flavor, while opting for the SD tea in terms of appearance and color. In conclusion, although freeze-drying allowed obtaining a product with a higher antioxidant capacity and antioxidant content than spray-drying, both drying methods may be considered suitable for the production of instant rosehip teas and ensure obtaining a functional food product.

The aim of this research is to examine the mental endurance and athlete injury anxiety levels of athletes interested in wrestling from some demographic perspectives. In the study, a descriptive scanning model was used. The universe of the research consists of athletes from various cities of Turkey who are interested in wrestling, and the sample consists of 341 athletes selected by random sampling method among wrestling athletes from Ankara, Gümüşhane, Istanbul, Samsun and İzmir, Kayseri. As a data collection tool, the demographic information form developed by the researchers was used "Athlete Injury Anxiety Scale". In the study, the assumption of normality was first examined with the Kolmogorov-Smirnov and Shapiro-Wilk tests in the statistical evaluation of the data. The research findings were given as n (%), mean and standard deviation values, and the findings were considered significant at the p<0.05 level. In the study, there was no significant relationship between age, undergraduate status and educational status variables, athlete injury anxiety levels and mental toughness levels; When the athlete's age, athlete's injury status, gender, number of nationality variables were examined, it was determined that there was a significant difference in some sub-dimensions of the mental toughness inventory and in the total scores of the scale. As a result, it can be said that demographic variables such as age, gender, being a national athlete are effective on the mental endurance and disability anxiety of the athletes.

Yılmaz, Hacı Ömer; Günen, Mehmet Akif
This study aims to evaluate the relationship of geographical factors, including precipitation, slope, air pollution and elevation with adult obesity prevalence in Türkiye (TR) using a cross-regional study design. Ordinary least squares (OLS) and geographically weighted regression (GWR) were performed to evaluate the spatial variation in the relationship between all geographic factors and obesity prevalence. In the model, a positive relationship was found between obesity prevalence and slope, whereas a negative significant relationship was determined between obesity prevalence and elevation (p < 0.05).
