Kurudirek, Fatma; Demir İmamoğlu, Zeynep; Ekici, Sümeyye
Objective: This study examined the effect of providing a lighted, rotating musical toy on preschool children’s pain and anxiety during a blood collection procedure. Methods: The randomized controlled study was conducted on a sample of children aged 4-6 years who applied to the blood collection unit of a state hospital in Turkey from July 1 through August 1, 2022. The data were obtained from 95 children who met the research criteria (48 in the control group and 47 in the intervention group). Stratification and block randomization methods were used to determine the experimental and control groups. The variables of gender and fear of interference were used in the stratification of the children. The Family and Child Information Form, Child Fear and Anxiety Inventory, and Wong–Baker Facial Expression Rating Scale were used to collect the data. Results: The pain scores of the children in the experimental group were found to be lower (1.42 ± 1.05) than those in the control group (2.81 ± 1.23), and the result was statistically significant (P < .001). During the procedure, the mean Child Fear and Anxiety Inventory score of the children in the experimental group (1.21 ± 0.97) was lower than that of the control group (2.72 ± 1.10), and the difference was statistically significant (P < .001). Conclusion: This study found that providing a lighted, rotating musical toy to children aged 4-6 during blood collection effectively reduced their pain and anxiety. In line with these results, it is recommended that nurses and parents use such a toy in blood collection units to reduce pain and anxiety in children.

Terminalia citrina (T. citrina) belongs to the Combretaceae family and is included in the class of medicinal plants in tropical countries such as Bangladesh, Myanmar, and India. The antioxidant activities of lyophilized water (WTE) and alcohol extracts (ETE) of T. citrina fruits, their phenolic content by LC-HRMS, and their effects on cholinesterases (ChEs; AChE, acetylcholinesterase, and BChE, butyrylcholinesterase) were investigated. Especially ten different analytical methods were applied to determine the antioxidant capacity. Compared with similar studies for natural products in the literature, it was determined that both WTE and ETE exhibited strong antioxidant capacity. Syringe and ellagic acids were higher than other acids in ETE and WTE. IC50 values for ETE and WTE in DPPH radical and ABTS⋅+ scavenging activities were calculated as 1.69–1.68 μg mL−1 and 6.79–5.78 μg mL−1, respectively. The results of the biological investigations showed that ETE and WTE had an inhibition effect against ChEs, with IC50 values of 94.87 and 130.90 mg mL−1 for AChE and 262.55 and 279.70 mg mL−1 for BChE, respectively. These findings indicate that with the prominence of herbal treatments, T. citrina plant may guide the literature in treating Alzheimer's Disease, preventing oxidative damage, and mitochondrial dysfunction.

Acaravci, Ali; Artan, Seyfettin; Hayaloglu, Pinar; Erdogan, Sinan
Since ancient times, corruption has been one of the essential topics for economists and politicians. Moreover, it is a concern for both developed and developing countries and a significant obstacle to economic development. The primary objective of this paper is to examine the relationships between corruption, economic growth, internet use, and quality of governance alongside other institutional and economic variables in 65 developed and developing countries for the period 1999–2016 by using dynamic panel data methods performing well under cross-sectional dependence. The empirical results can be summarized as follows. The augmented mean group (AMG) results indicate statistically significant relationships between corruption, economic growth, internet use, quality of government, and democracy. Also, we find that an increase in economic growth and quality of governance contribute to reducing corruption in these 65 developed and developing countries. In contrast, an increase in internet use and democracy level raises corruption. The policy implications of the empirical estimations are also discussed in the paper.

Çiftçi, Fida; Acet, Tuba; Saribiyik, Oǧuz Yunus
The factors such as global warming, wild irrigation, and synthetic fertilisers pollute the soil and increase salinity. The salinity is defined as salt stress for plants, and plants have developed various tolerance mechanisms to survive under salt stress conditions. Therefore, efforts to increase the tolerance of salt sensitive plants such as beans (Phaseolus vulgaris) are considered important. Additionally, considering problems that appear depending on global warming, understanding the tolerance mechanisms, and activating them by using natural and sustainable solutions are important for plant growth and preventing lower agricultural productivity. In this study, the effect of biofertiliser obtained from a small-scale bioreactor on a plant exposed to salt stress on the development of morphological, physiological, and biochemical properties of the model plant, Phaseolus vulgaris L. var. ellipticus Mart (Pve) were investigated. The biofertiliser application increased the amount of chlorophyll, flavonoids, anthocyanin, and proline while the amount of hydrogen peroxide and lipid peroxidation decreased in the plant. This change enhanced the enzyme activities of catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) and the plant formed tolerance to the salt stress. As a result, the biofertiliser application to the plant may activate the tolerance mechanism against salt stress.

Şan, Murat; Nacar, Sinan; Kankal, Murat; Bayram, Adem
The impacts of climate change on current and future water resources are important to study local scale. This study aims to investigate the prediction performances of daily precipitation using five regression-based statistical downscaling models (RBSDMs), for the first time, and the ERA-5 reanalysis dataset in the Susurluk Basin with mountain and semi-arid climates for 1979–2018. In addition, comparisons were also performed with an artificial neural network (ANN). Before achieving the aim, the effects of atmospheric variables, grid resolution, and long-distance grid on precipitation prediction were holistically investigated for the first time. Kling-Gupta efficiency was modified and used for holistic evaluation of statistical moments parameters at precipitation prediction comparison. The standard triangular diagram, quite new in the literature, was also modified and used for graphical evaluation. The results of the study revealed that near grids were more effective on precipitation than single or far grids, and 1.50° × 1.50° resolution showed similar performance to 0.25° × 0.25° resolution. When the polynomial multivariate adaptive regression splines model, which performed slightly higher than ANN, tended to capture skewness and standard deviation values of precipitations and to hit wet/dry occurrence than the other models, all models were quite well able to predict the mean value of precipitations. Therefore, RBSDMs can be used in different basins instead of black-box models. RBSDMs can also be established for mean precipitation values without dry/wet classification in the basin. A certain success was observed in the models; however, it was justified that bias correction was required to capture extreme values in the basin.

Terhan, Meryem; Özağdaş, Emre; Omar, Muhammed Arslan
In this study, the waste heat loss of flue gases from the boilers of Kafkas University district heating system has been calculated between 6-8% according to the combustion analysis and the annual cost of this heat loss has been found as $58,658.79. In terms of energy efficiency and the national economy, we think that this lost energy should be recovered as much as possible and fuel and energy savings should be achieved. In the paper, the effects of variants such as air excess coefficient, flue gas temperature, boiler capacity and fuel consumption on the heat recovery from flue gas have been presented in detail. The heat recovery scenarios have been presented for reusing this waste energy for space heating, domestic hot water, and preheating combustion air and the applicability of these scenarios has been investigated in terms of thermodynamics and economics. According to the results of the study, in the second scenario examined to cover the domestic hot water need of the guest house building, the energy savings of the scenario can be provided during 20 years of economic life is $122,820.83, and it has the highest savings income among the scenarios. In addition, it is possible to recover approximately 50% of the flue gas loss with thanks to the scenario. On the other hand, the third scenario of heating the boiler combustion air with waste heat is the easiest and most economical scenario because its payback period is only one year, and there are no extra excavation and pipe costs.

Erkencioglu, Bedriye N.; Zuhal, Mustafa; Tokel, Dilek; Ozyigit, Ibrahim I.
The COVID-19 pandemic has posed a significant impact on agriculture. Due to its importance in world trade and human life, the effects of the pandemic on the cotton economy were evaluated by using the data of important organizations such as the U.S. Department of Agriculture, the World Trade Organization, and International Cotton Advisory Committee in this study. With the Chow test, which measures of structural breaks, the effects of COVID-19 on cotton production and trade were examined. According to the Chow test results, the pandemic had no significant effect on cotton production, exports and imports in the People’s Republic of China and Türkiye, while being highly influential on cotton production and exports in the U.S. and Brazil. Distinctively, in Pakistan, it had a significant impact on cotton production and import. It was observed that although the demand, trade and prices for cotton were descended, the cotton prices started to recover with the increase in demand in the third quarter of 2020. In June 2022, the highest peak in cotton prices was observed. As a conclusion, it is shown that cotton production and trade during the pandemic were affected in all countries except People’s Republic of China and Türkiye. However, the marks of the effects of factors such as decreasing stocks, uncertainties in national economies, high inflation and increase in production costs on the cotton economy will be better understood in the coming years.

Akçay, Fatma; Şan, Murat; Nacar, Sinan; Kankal, Murat
Trend analysis benefits collecting and analyzing reliable data in climate change studies. In this context, long-term temperature and precipitation data analysis, two variables sensitive to climate change, is essential. This study aims to holistically and partially determine the annual trends of precipitation and temperature time series for 1970–2019 at nine selected stations in the Susurluk Basin, Turkey. The innovative trend significance test (ITST), innovative crossing trend analysis (ICTA) method, and Mann-Kendall (MK) test were used to determine holistic trends. Also, partial trends were determined using successive average methodology (SAM). For the precipitation variable, while an increasing trend was determined for the ITST, there was mostly no trend for the other methods. While a strong increasing trend was detected for the temperature according to the ITST and MK methods, no trend was observed in any station according to the ICTA method. According to the SAM results, the maximum trend durations for the peak and trough change points were 4.9 (10.3) and 5.3 (8.4) years, respectively, for precipitation (temperature). The strong temperature trends in the basin will likely continue, requiring precautions against extreme events such as drought.

- MakaleAçık Erişim2023Highly Efficient Spectrophotometric Determination of Cu2+ ion in Aqueous Medium Using a thiosemicarbazone–derivative Ligand
Başoğlu, Aysel; Ocak, Ümmühan; Iyidoğan, Ayşegül Karaküçük
A new simple spectrophotometric method for the determination of Cu2+ ion was developed using an thiosemicarbazone compound, 2-{4-[Bis(2-chloroethyl)amino]benzylidene}-N-[(4-methylthio)phenyl]hydrazinecarbothioamide (TSC). A simultaneous color change was observed (from colorless to bright yellow) by the addition of Cu2+ ion to the TSC ligand solution. The maximum absorbance of the TSC ligand measured at 366 nm was decreased by the presence of Cu2+ ion. The graphs of absorbance obtained by means of the Job’s method and the molar-ratio method proposed a complex formation with a 1:2 Cu2+–TSC ligand stoichiometry. The molar-ratio method with emission measurements also confirmed the stoichiometry. The complex stability constant of TSC–Cu2+ complex (K) was evaluated to be 1.76 × 105. The proposed spectrophotometric method was associated with the change in absorbance at 366 nm owing to the interaction between the TSC ligand and Cu2+ ion. From the spectrophotometric titration data, it was pointed out that TSC ligand (1.5 × 10− 5 mol L-1) selectively reacted with Cu2+ ion in DMSO/water (1:1, v/v, citrate buffer at pH = 6.0). The calibration curve for Cu2+ ion was obtained with a good linearity in the range of 0.0191–0.3241 mg L-1. The detection limit for Cu2+ ion was 0.0063 mg L-1. The proposed method was achievemently implemented in real water samples (drink water, tap water and, distilled water). Satisfactory recoveries were confirmed at three different concentrations. The method presented a relative standard deviation (RSD%) of less than 3.08%.

Alkan, Hamdi; Öztürk, Serkan; Akkaya, İsmail
The Yedisu Seismic Gap is one of the most important seismic gaps throughout the North Anatolian Fault Zone since it has not produced destructive earthquakes for a long time. To analyze the characteristics of future seismic hazards, the interrelationships between seismotectonic b-values, Coulomb stress changes, and S-wave velocity models of crust are presented in and around the Yedisu Seismic Gap located northwest of the Karlıova Triple Junction. For this purpose, the most up-to-date earthquake catalog and the focal mechanism solutions of recent earthquakes are used to image the different depth intervals. Results show that the relatively positive stresses are accumulating along the Varto Fault Zone and Kargapazarı and Yedisu Segments between 5 and 15 km depth intervals. At the same time, the lower b-values between 0.6 and 1.0 are found in the same segments. However, in the volcanic regions around the Karlıova Triple Junction, the low S-wave velocity zones may be related to high b-values, negative stress changes, and volcanic structures. The region between the Turnadağ volcano and the Varto caldera shows scattered stress and b-value changes in the upper crust. Moreover, the probability of earthquakes for Mw = 6.0, 7.0, and 7.7 in the intermediate term (10 years) is estimated as ~ 65%, ~ 17%, and ~ 5%, respectively. Recurrence of earthquakes with Mw = 6.0, 7.0, and 7.7 are calculated as ~ 10, ~ 55, and ~ 187 years, respectively. Consequently, the regions characterized by low strong b-values and positive stress loading reveal high earthquake hazard potential on the whole in the next decade.

Vaissi, Somaye; Kurnaz, Muammer; Şahin, Mehmet Kürşat; Hernandez, Axel
The degree to which closely related species conserve or diverge in their niche characteristics may provide insight into evolutionary and diversification processes, as well as some understanding of broad-scale biogeographic patterns. In this study, we used an ensemble of 10 algorithms to predict the distributions of 12 Ablepharus species in geographical (G)-space for the recent time and the future (2081–2100) climate conditions. Niche overlap, equivalency, and similarity tests in environmental (E)-space were used to test niche divergence and conservatism. The consensus model showed that temperature seasonality (n = 6) and annual precipitation (n = 3) were the major factors predicting the distribution of 75% (9 out of 12) of the species. The ensemble models based on ssp585 predict that 83.33% of the species (n = 10) may have contracted their ranges, especially at lower altitudes along their southern margins. They may have also expanded northward during this period. However, in the ssp126, most species’ distribution ranges may remain unchanged despite contractions and expansions. Based on multivariate niche analyses, the distributions of 28 and 11 paired comparisons explored in this study significantly diverged and conserved. We found that closely related species inhabit different habitats and respond to their climatic characteristics, indicating that ecology has a significant influence on speciation.

Duran, Celal; Ozeken, Sengul Tugba; Camoglu, Aslihan Yilmaz; Ozdes, Duygu
Natural mulberry leaves and carboxylic acid-modified mulberry (Morus alba L.) leaves were used for the first time to scrutinize the effects of modification on the retention efficiency of an anionic dye (Remazol Brilliant Blue R (RBBR)) from aqueous solutions to suggest an economical and promising adsorbent for the treatment of dye-contaminated water. The characterization of the adsorbents was accomplished through common techniques including SEM, FTIR, and pHpzc determination. Several parameters studied in batch experiments pointed out that the initial pH of 2.0 and the contact time of 240 min were optimum conditions for all the developed RBBR uptake processes. An artificial neural network (ANN) model was applied to formulate a forecast model for the uptake efficiency of RBBR. The experimental data were assessed by different kinetic and isotherm models to explain the mechanism of the developed processes in more detail. Maximum monolayer adsorption capacities of natural mulberry leaves and acetic acid-, citric acid-, and oxalic acid-modified mulberry leaves were determined as 64.5, 95.2, 84.8, and 91.7 mg g1, respectively, by the Langmuir isotherm model. These results demonstrated that the modification with carboxylic acids significantly increases the anionic dye adsorption capacity of the mulberry leaves.

Kızılcık, Onur; Birdir, Kemal
In this study, information will be explored that will contribute to increasing tourism income in destinations with low tourist expenditure per person. For this purpose, the souvenir expenditure of tourists in Turkey is examined. Souvenir stores in Sultanahmet and the Grand Bazaar in Istanbul were investigated using a qualitative case study research design. Semi-structured interviews were conducted with 11 souvenir sellers and 778 online comments of tourists shopping in souvenir stores were analyzed by netnography. As a result of the research, it has been determined that the efforts made to transform products based on the natural, historical and cultural richness of Turkey into brands, and thus increase local product diversity, play a critical role in increasing souvenir expenditure. On the other hand, the importance of the selection of high spending tourists as the target market and increasing the employment of qualified workers in the tourism sector has emerged.
