Yüzer, Mustafa O.; Gençcelep, Hüseyin
Sesame (Sesamum indicum L.) is an erect herbaceous annual plant with flat seeds. It is one of the oldest cultivated oilseed plants in the world, especially popular in Africa and Asia. The present research objective was to describe a sesame protein isolate, i.e., its amino acid profile, functional and physicochemical properties, zeta potential, and hydrodynamic diameter. The surface charge and hydrodynamic diameter in aqueous solutions were obtained for standard sesame seeds, defatted sesame seeds, and the sesame protein isolate. Defatted sesame seeds yielded the following optimal parameters: salt concentration – 0.6 M, pH – 7, iso-electric point (pI) – 4. The sesame protein isolate was rich in methionine content, which is rare in other plant proteins, but its lysine content was lower than in other isolates. The sesame protein isolate displayed almost identical zeta potential profiles with its pH. The decreasing pH increased the zeta values gradually from the lowest negative value to the highest positive value. The zeta potentials of standard and defatted sesame seeds at pH 7 were –23.53 and –17.30, respectively. The hydrodynamic diameter of the sesame protein isolate (0.33 μm) was smaller than that of sesame seeds (2.64 μm) and defatted sesame seeds (3.02 μm). The sesame protein isolate had a water holding capacity of 1.26 g/g and an oil holding capacity of 3.40 g/g. Its emulsifying properties looked as follows: emulsion capacity – 51.32%, emulsion stability – 49.50%, emulsion activity index – 12.86 m2/g, and emulsion stability index – 44.96 min, respectively. These values are suitable for the sesame protein isolate and are consistent with the literature. The sesame protein isolate was a good source of protein (88.98%). Using sesame proteins as functional components can be an important basis for better knowledge of the relationship between electrical charge interactions in food matrices and the structure, stability, shelf life, texture, structural and functional properties of food. Research prospects include the effects of sesame protein isolates on various food systems.

The aim of this study was to evaluate the effect of alexithymia severity on attitudes toward hypertension prevention in adults. In the literature, the effects of alexithymia severity on attitudes toward hypertension prevention in adults have not been clearly elucidated. However, it has been reported that alexithymia is a possible risk factor for various medical conditions and may increase predisposition to diseases. This cross-sectional study included 358 adult individuals. Study data were collected with a personal information form, the Toronto Alexithymia Scale, and the Attitudes Toward Prevention of Hypertension Scale. The data was collected between December 12, 2022, and March 10, 2023. Relationships were analyzed by multiple linear regression. Findings were reported according to the STROBE guidelines. A weak negative correlation was found between the total scores of the Toronto Alexithymia Scale and Attitudes Toward Prevention of Hypertension Scale. The variables of educational status, smoking, having a family member with hypertension, and alexithymia were statistically significant predictors of attitudes toward hypertension prevention. It was further determined that these variables explained 7.6% of the variance in attitudes toward hypertension prevention. Alexithymia severity in adults affects their attitudes toward hypertension prevention. Determining the severity of alexithymia in adults may assist health professionals in implementing initiatives to improve the condition of alexithymia. In addition, new positive behaviors can be developed to prevent hypertension in adults.

Uyar, M.
When flexible manipulators complete their movements to the desired position, vibrations occur at the endpoint. Reducing vibrations is an important advantage for eliminating positioning errors and monitoring position accuracy. However, the increase in vibration amplitudes leads to the inability to complete the planned tasks in the applications and results in loss of productivity. Therefore, the reduction of end-effector vibrations is an important research area. In this study, a motion-based control (MBC) method with designed motion profiles is introduced to reduce the endpoint vibrations of epoxy–glass-reinforced composite manipulators. Three different motion profiles, namely Modification-1, Modification-2, and Modification-3, are designed according to time and maximum velocity values depending on the system's frequencies. For the design of Modification-1, variable deceleration and acceleration times are considered, while for Modification-2 and Modification-3, both the maximum angular velocity and the deceleration and acceleration times are utilized. For two different angular positions and motion times, all motion profiles are applied to two composite manipulators with different frequencies, and the results are experimentally and numerically obtained to examine the vibration performance of MBC. Simulation results confirmed with experiments are achieved using mathematical models in ANSYS. To evaluate the effectiveness of MBC, the change in RMS values of endpoint vibration responses and the reduction rates are presented comparatively for all motion profiles. The results show significant advantages for the MBC method, reducing vibrations by approximately 99%, and eliminating positioning errors caused by vibrations.

Çorapsız, Muhammed Reşit; Kahveci, Hakan
Energy management in hybrid energy storage systems (HESSs) consisting of battery and supercapacitor packages has an essential role in the efficient and safe use of energy storage devices. In the mentioned HESSs, with frequency separation-based energy management, the source with slow dynamics (eg, batteries) is supported by other sources with fast dynamics (eg, supercapacitors). To realize power sharing in the battery/supercapacitor HESS, the load current is divided into low- and high-frequency components and supplied/allocated from energy storage devices. This review touches on the historical development of electric vehicles and includes extensive information about the battery and supercapacitor. It also comprehensively analyzes frequency separation-based power allocation strategies for battery/supercapacitors HESS. These strategies were investigated in detail regarding their features, advantages, and restrictions. In addition, interconnection circuit topologies and control techniques used in frequency-based power allocation were explained comprehensively. As a result, this study will serve as a guide on frequency-based power separation principles in HESS.

Soylu, Özgür Bayram; Adeleye, Bosede Ngozi; Ergül, Murat; Okur, Fatih; Lorente, Daniel Balsalobre
Purpose: Since competitiveness is crucial in international trade, this paper contributes to the literature by interrogating the information and communication technology (ICT)-trade nexus on competitiveness in Eastern and Western European countries. Does ICT usage promote or hinder the impact of trade openness on competitiveness? This study attempts to answer two questions: (1) is the interaction of trade and ICT significant in promoting competitiveness? (2) Is the effect significantly different by European classification? Design/methodology/approach: With data on 17 European countries from 2007 to 2020 and using mobile phones and fixed telephone usage as ICT indicators, the study engages the bootstrapped ordinary least squares (BOLS) and method of moments quantile regression (MM-QR) techniques to probe the discourse. Findings: The empirical findings reveal that (1) the interaction of trade and ICT boost competitiveness; (2) the effect of mobile phone is consistent across the full, East, and West European samples; (3) the interaction effect is also significant across the conditional distribution of competitiveness and (4) mobile phones and fixed broadband usage reveal “leapfrog” effect across the quantiles. Overall, the study submits that ICT usage will enhance the impact of trade, and thus, ICT is a critical enabler of competitiveness in Europe; policy recommendations were discussed. Originality/value: To the best of the authors' knowledge, this is the first study examining the interaction effect of trade openness and ICT usage on competitiveness in Europe. In other words, the authors attempt to analyze how ICT usage influences trade-competitiveness dynamics. To fill the gap in the literature, the authors' use a sample of 17 European countries from 2007 to 2020. The variables of interest are the competitiveness index, trade openness, and four ICT indicators (mobile phone, fixed telephone subscriptions, fixed telephone subscriptions, and Internet users).

Uslu, Emin; Tiğli, Ahmet; Çolak, Murat
The mechanical properties of aluminium alloys can be increased by controlling the grain size and morphology of the alloy. In these studies, mechanical vibration, cooling slope plate (CSP), and grain refiner were applied on sand mould casting using A380 alloys. The hardness, and microstructure of the cast samples are investigated. These processes lead to the refinement of grain structures and a decrease in the tendency for dendritic structure formation. The Effect of the solidification time (modulus) on the microstructure is investigated. It was determined that the solidification time varies depending on the section thickness, which affects the SDAS values. It was observed that the lowest SDAS values were in CSP and the highest values were in grain refiners added casting. The lowest hardness value was recorded at CSP casting. Meanwhile, the grain refiner added vibration casting exhibits the highest hardness.

- MakaleAçık Erişim2024Scopus SJRQ3Durability of slag-based alkali-activated materials: A critical review
Gökçe, H.S.
As the world becomes increasingly aware of the devastating effects of climate change, the need for sustainable building materials that are both durable and environmentally friendly increases. Geopolymer and alkali-activated materials formed by a chemical reaction between an alkaline activator solution and an aluminosilicate source have gained popularity in recent years. The alkaline activator solution dissolves the aluminosilicate source, which then undergoes a polycondensation reaction to form a three-dimensional geopolymeric gel network. The development of this network ensures the strength and durability of the material. Today, this phenomenon of durability has been studied in detail to enable the development of superior construction materials, taking into account degradation mechanisms such as carbonation, leaching, shrinkage, fire, freezing and thawing, and exposure to aggressive environments (chlorides, acids, and sulphates). Although there are many unsolved problems in their engineering applications, slag-based alkali-activated materials appear to be more advantageous and are promising as alternative materials to ordinary Portland cement. First of all, it should not be ignored that the cure sensitivity is high in these systems due to compressive strength losses of up to 69%. Loss of strength of alkali-activated materials is considered an important indicator of degradation. In binary precursors, the presence of fly ash in slag can result in an improvement of over 10% in compressive strength of the binary-based alkali-activated materials after undergoing carbonation. The binary systems can provide superior resistance to many degradation mechanisms, especially exposure to high-temperature. The partial presence of class F fly ash in the slag-based precursor can overcome the poor ability of alkali-activated materials to withstand high temperatures. Due to the desired pore structure, alkali-activated materials may not be damaged even after 300 freeze–thaw cycles. Their superior permeability compared to cementitious counterparts can extend service life against chloride corrosion by more than 20 times. While traditional (ordinary Portland cement-based) concrete remains the most widely used material in construction, geopolymer concrete’s superior performance makes it an increasingly emerging option for sustainable and long-lasting infrastructure.

Peker, Hüseyin; Ayata, Ümit
In this study, surface changes (whiteness index: WI*, color parameters, and glossiness properties) occurring after bleaching with oxalic acid (C2H2O4) and hydrogen peroxide (H2O2) + sodium hydroxide (NaOH) chemicals in kingwood (Dalbergia cearensis Ducke) wood, used for high-quality applications such as quality turning, marquetry, furniture, inlay work, musical instruments, and decorative items, were investigated. The ΔE* values were determined as 5.46 for the single component and 8.69 for the double component. Decreases in L* and ho parameters were obtained by the action of the C2H2O4 chemical, while increases were observed in the a*, C*, and b* parameters. Additionally, the use of H2O2 + NaOH chemicals in the bleaching process resulted in increases in L*, b*, C*, and ho values, with a decrease noted in the a* parameter. Observations revealed reductions in glossiness values at 60 and 85 degrees when employing two distinct bleaching agents in both orientations. It can be said that the bleaching agents used in the study exert varying effects as modifiers on the surface of wooden materials.

Çınar, İrfan; Gıdık, Betül; Dirican, Ebubekir
Background: This study aimed to investigate the cytotoxic, apoptotic, invasion, metastasis, and heat shock proteins (HSPs) effects of N. sativa oil on breast and gastric cancer cells. Methods: We assessed the cytotoxic and apoptotic effects of various concentrations of N. sativa oil (10-50-100-200 µg/mL) on MCF7 breast cancer and AGS, an adenocarcinoma of the gastric cell line, at 24, 48 and 72 h using the MTT test. Additionally, the expression of the Caspase-3, BCL2/Bax, MMP2-9 and HSP60-70 gene was examined using RT-PCR in cell lines treating with N. sativa. Results: The MTT experiments demonstrate that N. sativa has a time and dose-dependent inhibitory effect on the proliferation of MCF7 and AGS cancer cells. The vitality rates of MCF7 and AGS cells treated with N. sativa were 77.04–67.50% at 24 h, 65.28–39.14% at 48 h, and 48.95–32.31% at 72 h. The doses of 100 and 200 µg/mL were shown to be the most effective on both cancer cells. RT-PCR analysis revealed that N. sativa oil extract increased caspase-3 levels in both cell lines at higher concentrations and suppressed BCL2/Bax levels. Exposure of MCF7 and AGS cell lines to N. sativa caused a significant decrease in the expression of MMP2-9 and HSP60-70 genes over time, particularly at a dosage of 200 µg/mL compared to the control group (p < 0.05). Conclusions: Our findings indicate that N. sativa oil has a dose-dependent effect on cytotoxicity and the expression of apoptotic, heat shock proteins, and matrix metalloproteinases genes in breast and gastric cancer.

Mercan, Emin
This study aimed to determine the effects of the ozone treatment of film-forming solutions (FFSs) containing whey protein concentrate (WPC) and gelatine on biopolymer films’ physical, mechanical, and thermal properties. Film samples were produced from a FFS that was ozone-treated at 0 (control), 5, 10, and 30 min. Ozone treatment caused an increase in the pH values of the FFS, whereas the zeta potential remained negative. The films became lighter in colour, slightly greenish, and more opaque with longer ozonation times. The control sample showed the highest thermogravimetric weight loss (92.15%). The weight loss of the samples decreased with increasing ozone treatment time. The application of ozone treatment on the FFS enhanced the films’ mechanical properties. Increased ozone treatment time improved the film samples’ tensile strength, elongation at break, and toughness values. In conclusion, the results of this study demonstrate that the ozone treatment of FFS containing whey protein concentrate and gelatine can significantly enhance the physical, mechanical, and thermal properties of biopolymer films. These results highlight the potential of ozone treatment as a viable method for improving the performance and quality of biopolymer films used in food packaging, offering promising advantages for sustainable and environmentally friendly packaging solutions.

Background: Genetic and epigenetic mechanisms have been shown to play a role in the pathogenesis of atopic dermatitis (AD). However, the role of genes involved in the establishment of DNA methylation has not yet been demonstrated. Methods: A total of 15 pediatric patients with AD and 15 healthy volunteers were included in this study. The mRNA gene expression levels of eight different genes involved in the regulation of DNA methylation were examined in the blood and tissue samples. Results: The mRNA expression levels of DNMT3A genes were significantly increased, while the mRNA expression levels of DNMT3B, TET1, and TET2 genes were statistically significantly reduced in the lesional tissue of patients compared to the control group. It was observed that the mRNA expression levels of DNMT1, DNMT3A, and TET3 genes were increased, while the mRNA expression levels of DNMT3L and TET1 genes were found to be decreased in the blood of the patients. Conclusion: The results indicated that the DNA methylation pattern in the patients was hypermethylated, especially in the lesional tissue. The data obtained may contribute to the understanding of the epigenetic regulation of AD and aid in the development of new diagnostic and treatment options.

Yıldırım, Ümit
This study aimed to investigate groundwater vulnerability to pollution in the Upper Kelkit Valley (NE Turkey). For this purpose, vulnerability index maps were created using the generic DRASTIC and AHP-DRASTICLu models. The latter model was suggested by adding a parameter to the DRASTIC model and weighting its parameters with the analytical hierarchy process with the GIS technique. The results showed that areas with high and very high vulnerabilities are concentrated around the Kelkit Stream, which flows from east to west in the central part of the study area. In contrast, areas with low and very low vulnerability classes are located in the northern and southern parts of the study area. To validate the model results, a physicochemical characterization of groundwater samples and their corresponding vulnerability index values were statistically compared using the Spearman correlation method. In addition, the single-parameter sensitivity method was applied to analyze the models’ sensitivities. Results revealed a stronger correlation between the vulnerability index values of the AHP-DRASTICLu model (compared to the DRASTIC model) in terms of sulfate (R2 = 0.75) and chloride (R2 = 0.76), while there was a slightly weaker correlation for the electrical conductivity (R2 = 0.65) values of the groundwater samples. Sensitivity analysis indicated that the vadose zone, aquifer media, and land use are the most influential parameters responsible for the highest variation in the vulnerability index. Generally speaking, the results indicated that the AHP-DRASTICLu model performs better than the DRASTIC model for investigating groundwater vulnerability to pollution in the Upper Kelkit Valley.

Kökhan, Ahmet; Kökhan, Serhan; Gökdalay, Meriç
Purpose: The purpose of this study is to develop an operational level decision support system model for air traffic controllers (ATCos) within the framework of the Flexible Use of Airspace (FUA) concept to enable more efficient use of airspace capacity. This study produces a systematic solution to the route selection process so that the ATCo can determine the most efficient route with an operational decision support system model using Dijkstra’s Shortest Path Algorithm. Design/methodology/approach: In this study, a new decision support system model for ATCos in decision-making positions was recommended and used. ATCos use this model as a main model for determining the shortest and safest route for aircraft as an operational-level decision support system. Dijkstra Algorithm, used in the model, is defined step by step and then explained with the pseudocode. Findings: It has been determined that when the FUA concept and DSS are used while the ATCo chooses a route, significant fuel, time and capacity savings are achieved in flight operations. Emissions resulting from the negative environmental effects of air transportation are reduced, and significant capacity increase can be achieved. The operational level decision support system developed in the study was tested with 55 scenarios on the Ankara–Izmir flight route compared to the existing fixed route. The results for the proposed most efficient route were achieved at 11.22% distance (nm), 9.36%-time (min) savings and 837.71 kg CO2 emission savings. Originality/value: As far as the literature is reviewed, most studies aimed at increasing airspace efficiency produce solutions that try to improve rather than replace the normal process. Considering the literature positioning of this study compared to other studies, the proposed model provides a new systematic solution to the problems that cause human-induced route inefficiency within the framework of the FUA concept.

Background: Two earthquakes of magnitude 7.7 and 7.6 occurred in the Turkish province of Kahramanmaraş in 2023. The earthquakes resulted in serious losses of life and property in 11 provinces, and the injured were transferred to other provinces for treatment and care. To date, no studies on the experiences of intensive care nurses providing care to earthquake victims after the Kahramanmaraş earthquake sequence have been identified. Aim: The aim of the present study is to explore the experiences of intensive care nurses providing care to earthquake victims who were transferred to other provinces. Study Design: A qualitative descriptive research design with conventional content analysis was used. Snowball sampling was used in the selection of intensive care nurses. Data saturation was achieved with 20 nurses. In-depth interviews were conducted with the participants through phone between March 8 and March 15, 2023. MAXQDA 20 software was used for data analysis. The COREQ checklist was used to guide the reporting of the study. Results: Twenty nurses were recruited. Four themes emerged from the data: challenges in caregiving processes; psychological challenges; ethical situations; urgent need for training and support. Conclusions: After the Kahramanmaraş earthquake sequence, described by some as the disaster of the century, nurses encountered patients with unique needs that they had never encountered before and tried to cope with the constantly changing health conditions. For this reason, they were affected psychologically and experienced challenges in caregiving processes. Relevance to Clinical Practice: Conducting comprehensive training for diseases common among earthquake victims, developing new protocols for providing care to earthquake victims, developing more action plans for nurses, and psychologically supporting intensive care nurses would facilitate the caregiving processes.
