Sevim, Sumeyra; Macit, Arife; Kizil, Mevlude
Throughout history, Turkish coffee has been the most widely consumed type of coffee in Turkey. Therefore, the goal of this study was to determine the amount of ochratoxin A (OTA) present in Turkish coffee and to analyze any potential health hazards. A total of 41 Turkish coffees were collected and analyzed for OTA activity using a competitive enzyme immunoassay (ELISA). Furthermore, dietary exposure and health risk assessments for the Turkish population were calculated based on analytical results and coffee consumption data from the Turkish Nutrition and Health Survey 2019 (TNHS-2019) in three age categories (15–18, 19–64, and 65 + years). Nine of the samples contained more than 2.5 μg/kg OTA, with an average of 5.24 μg/kg. The OTA concentration in 3 samples exceeded the permissible maximum limit (5 μg/kg) established by Turkish legislation, and the mean concentration was 8.41 μg/kg. A margin of exposure (MOE) approach was used for risk characterization, considering both non-neoplastic and neoplastic consequences. There were no concerns about health risks because MOEs were more than 10,000 for all categories. Although the levels of OTA analyzed in Turkish coffee did not pose a risk to individuals in the three age categories, emphasis should be placed on minimizing and controlling OTA concentrations in Turkish coffee. Additionally, it is also necessary to consider other food sources that could contribute to OTA exposure.

The fabrication and characterization of high-performance devices for optoelectronic applications, particularly their response to incident light, are crucial. In this study, a MnPc/DLC device was fabricated using thermal evaporation and magnetron sputtering techniques, and its fundamental optoelectronic properties were characterised. Key diode parameters including barrier height, ideality factor, reverse saturation current, series resistance, and shunt resistance were determined using several methods, such as TE, Ohm's Law, the modified Norde method, and the Mikhelashvili method. The results from these methods were found to be consistent with varying light intensities. Additionally, photodetector parameters of the MnPc/DLC device were measured at ±1 V under light intensities of 20, 40, 60, 80, and 100 mW/cm2, and the findings were compared with the literature. The maximum values for photocurrent, photoresponsivity, photosensitivity, specific detectivity, and on/off ratio were 6.41 × 10−2 A, 2.49 A/W, 2.02 × 105, 5.8 × 109 Jones and 2.06 × 103, respectively. Notably, the photocurrent, photoresponsivity, photosensitivity, and on/off ratio values were found to be significantly higher and more promising compared to those reported in the literature.

Danismaz, Harun
Palu Kalesi is a fortress site situated in modern Elazig province. In the Middle Iron Age, this region was the western borderland of the Urartian Kingdom and the primary contact zone where political and cultural relations transpired between the Urartu and the neighbouring Neo-Hittite kingdoms. The site was also a strategically crucial military post that provided logistic support for the Urartian armies during their western expeditions. The fortress was built as a provincial centre shortly after the foundation of the Urartian Kingdom, and the settlement lasted for a long time until the fall of the kingdom. This study presents previously unrecognised archaeological remains, which were identified during our recent investigations at Palu Fortress. Our survey of the site revealed that the Middle Iron Age citadel consisted of two sectors, and the Lower Citadel was enclosed by sturdy fortifications and terrace walls reinforced with bastions. Moreover, while Urartian rock signs were already recorded at Palu, our investigations documented previously unknown rock signs at the site. In addition, other previously unrecognised features dating to the post-Urartian periods were identified by our recent investigations, including five single-roomed rock-cut tombs and two stepped rock-cut tunnels. To better understand the relationship of the archaeological features at the site, a topographic map of Palu Fortress was drawn and visible archaeological remains dated to the Urartian and post-Urartian periods were marked on this map. In addition, the multi-roomed tombs of the Urartian period were scanned using Lidar sensors, and Lidar data were used to generate 3D models and rectified plans of the tombs. Finally, a preliminary virtual 3D reconstruction of the Urartian period fortifications was generated on the basis of recently discovered remains.

This paper explores the applicability of one-dimensional (1D) nonlinear (NL) and equivalent-linear (EL) site response analyses (SRA) for characterizing site effects at selected strong ground motion stations impacted by the February 6, 2023 Türkiye earthquakes. The 1D NL simulations generally underestimate site response at softer sites and for long periods likely due to basin effects and the uncertainties associated with site properties and the 1D approximation. The inclusion of the high-frequency spectral decay parameter (κ0) in 1D simulations decreases the prediction bias of nonlinear SRA, especially at soft sites for short periods. Moreover, the theoretical transfer functions (TTFs) are demonstrated to capture the fundamental site period through in horizontal-to-spectral vertical ratio (HVSR) using ground motion data before and after the February 6, 2023 main event.

Çelik, Duygu
This chapter focuses on the use of "kilams" in Kurdish theatre as theatre music. Kilams are the narratives, expressions, and structures of dengbêjî's, which are traditional one-person oral performances of the Kurds. çelik will look at the dramaturgical contributions of the kilams used in the plays she has selected. She will combine methods of performance analysis with the evaluation of play texts, play recordings, field diary entries and notes, as well as (non-standardised) interviews. In this way, the author aims to understand the concept of "theatre music" via an ethnodramaturgical performance analysis. The concept of ethnodramaturgy refers to the analysis of the political/artistic/anthropological identity that people/society creates via performing arts. The main goal of the proposed notion of ethnodramaturgy is to make the theatre of "the other" visible and analyse the ethnocentric monocultural structure in the field of theatre by deconstructing it. Here, the focus will be on Kurdish theatre and dengbêjî. For this purpose, three Kurdish plays in which kilams were used as theatre music will be discussed and their respective functions on stage analysed.

Plastic pollution ranks among the most severe environmental disasters caused by humans, generating millions of tonnes of waste annually. The extensive and unregulated use of plastics has led to ecotoxicity and environmental imbalance. Microplastics (MPs) are prevalent in aquatic environments, and these MPs further degrade into even smaller particles known as nano-plastics (NPs). Both MPs and NPs impact the environment by readily absorbing organic pollutants and pathogens from their surroundings, owing to their bigger surface area to volume ratio. This review focuses on the source of origin, bioaccumulation, and potential impact of MPs and NPs on aquatic organisms and human health. Additionally, the review explores various methods employed for identification and quantification of these particles in aquatic ecosystems. Sufficient information is available on their characteristics, distributions, and effects on marine ecosystems compared with freshwater ecosystems. For plastic particles <10 μm, more toxicological effects were observed compared with larger size particles, in aquatic life. Understanding the mechanism of action and ecotoxicological effects of micro/nano-plastics on the health of aquatic life across various trophic levels, as well as human health, is of utmost importance. We address knowledge gaps and provide insights into future research approaches for a better understanding of the interactive mechanisms between binary pollutants.

Synthesis of two-dimensional (2D) titanium carbide (Ti3C2Tx), with the name of MXene, by etching Ti3AlC2 (MAX) for different times 20 (v/v) % hydrofluoric acid (HF) at 40 °C was carried out. The influences of time, temperature and source of MAX on the synthesis of MXene were researched. The MXenes produced were characterized by fourier-transform ınfrared (FT-IR) spectroscopy technique, energy dispersive x-ray spectroscopy (EDX), scanning electron microscopy (SEM), x-ray diffraction (XRD) and thermogravimetry (TG) instruments. Above 390 °C, MXene layers were considerably oxidizing and forming anatase and rutile phases of TiO2 under air atmosphere. The resistance of MAX and MXene was 3.6 Ω and 116 Ω, respectively. However, the resistance of the residual part of MXene heated to 620 °C considerably increased to 17850 Ω. This behavior is another important piece of evidence showing that the MXene crystal structure has changed significantly and transformed into a new chemical structure containing anatase and rutil titanium oxide (TiO2). The dielectric loss (ϵ’’) and alternating conductivity (δac) of the MAX and MXenes were determined from their impedance measurements. The ϵ’’ and δac values of MXene were compared with those of MAX. Direct curent conductivities of MAX and MXene produced for 24 h were found to be 0.016 S/cm and 0.0023 S/cm, respectively.

Introduction: During pregnancy, sexual distress is common, but its prevalence and underlying factors require elucidation. This study was performed to investigate sexual distress in pregnant women. Methods: This research was designed as a descriptive and multi-center study. The study included 2365 pregnant women from 6 geographical regions of Turkey between April 1, 2022, and February 1, 2023. Data was collected using the “Pregnant Information Form” and “Female Sexual Distress Scale-Revised (FDS-R).” Descriptive statistics, independent sample t-test, analysis of variance, and the Pearson correlation test were used for data analysis. Results: Herein, 46.1% of pregnant women experienced sexual distress, and the mean FDS-R score of the study participants was 14.49. Participants who were dissatisfied with their sexual life before and during pregnancy (p < 0.001), those who did not have sexual intercourse during pregnancy (p < 0.001), those who experienced decreased sexual desire during pregnancy (p < 0.001), those who did not receive sexual education during pregnancy (p < 0.001), and those who experienced problems when engaging in sexual intercourse during pregnancy (p < 0.001) experienced more sexual distress. Sexual distress increased when the mean age and the number of pregnancies and children increased, whereas it decreased when the gestational week increased. Conclusions: Approximately half of the pregnant women included in the study experienced sexual distress. The findings highlight the importance of midwives and nurses encouraging pregnant women to discuss their sexuality. Policy implications: The findings of this study show that sexual distress during pregnancy is common and affected by some factors related to personal and sexual life during pregnancy. This result provides evidence of the need to develop culturally appropriate interventions and policies that include sexual partners in the context of improving pregnant women's sexual distress, sexual health, good family relationships and mental health.

The garden-city model, characterised by sprawling urban expansion and extensive open spaces, features green and water surfaces alongside substantial road networks, large parking lots and unshaded lands. This diverse landscape contributes to uneven air temperature distribution within the city. Our study investigated urban heat island (UHI) patterns in various urban environments within Putrajaya, focusing on rural, business, residential and near-water areas. Atmospheric data were collected over a year. Putrajaya exhibits two distinct UHI patterns: cool-day-hot-night in residential zones and hot-noon-temperate-elsewhere in impermeable areas. Business areas display alternating patterns based on seasonal climatic conditions and anthropogenic factors. The efficacy of artificial water bodies as a UHI countermeasure in garden cities depends on the size of the water body and the nature of the surrounding land cover. Shaded and green areas exhibit UHI intensities limited to 3°C, while impermeable areas, regardless of proximity to water surfaces, experience UHI up to 6°C. Overall, the garden-city model tends to restrict UHI variations within −1 to 3°C compared to −2 to 4°C in nearby Kuala Lumpur.

The study investigated antioxidant biomarkers in Dreissena polymorpha to evaluate the efficiency of Fenton process (FP) in Organized Industrial Zone Wastewater (OIZW) treatment. Antioxidant enzymatic activities, including superoxide dismutase (SOD) and catalase (CAT), glutathione peroxidase (GPX), non-enzymatic antioxidants (GSH) and the indicator of lipid peroxidation (TBARS) were measured in D. polymorpha in response to treated OIZW by FP. The performance of the FP has been optimized with response surface methodology (RSM). The optimum conditions (reaction time, and H2O2 and Fe2+ concentration) for OIZW by the FP process were determined. The results showed that the highest COD removal efficiency (83.94 %) was obtained when as Fe2+ concentration=402.35 mg/L, H2O2 concentration=4100.30 mg/L, and reaction time=10.10 min (desirability=1.000). SOD and CAT enzyme was decreased in the 1/25 diluted OIZW group compared to control group. CAT and SOD enzyme activities were increased after treatment compared to control groups. No statistically significant changes were observed in GSH levels and GPx activities. TBARS levels were increased 1/25 diluted OIZW exposure groups compared to the control group. TBARS levels were decreased after treatment. The results revealed that antioxidant parameters are useful biomarkers for determining the treatment efficiency of the FP.

Artuğer, Fırat
Cryptography aims to design algorithms for the protection of important data transmitted over unsecured networks. These algorithms encrypt the data and render it incomprehensible even if it is captured by enemies. Today’s data encryption standard is the AES algorithm. The most important and nonlinear unit in the AES algorithm is the s-box structure. The S-box provides the mixing process in the algorithm, that is, the confusion. An s-box structure with a high nonlinearity value greatly increases the security against various attacks. Therefore, s-box is of vital importance in an encryption algorithm. When we look at the literature, chaos-based s-box structures are frequently used. However, the nonlinearity value of s-boxes produced with chaos is low. In this article, a new, fast, and very simple method is proposed to increase the nonlinearity value of chaos-based s-box structures. In the proposed method, the nonlinearity value is calculated by changing the places of the elements respectively. When the nonlinearity value increases, the s-box is updated, and the next element is passed. In this way, many iterations are not looked at in vain. This saves a lot of time. As a result of the analysis, it has been proven that the s-box structure obtained by the proposed method is cryptographically strong and has a high nonlinearity value. It is thought that the proposed method will provide many advantages for future cryptography applications.

Background and Objectives: In this study, the effects of a six-week training program and various diets on subfatin, asprosin, irisin, leptin, ghrelin and the lipid profile were investigated in overweight women. Materials and Methods: A total of 78 women voluntarily participated in the study. Groups: The study was divided into eight groups: Healthy Control, Obese Control, Obese + Vegetarian, Obese + Ketogenic, Obese + Intermittent Fasting, Obese + Exercise + Vegetarian, Obese + Exercise + Ketogenic and Obese + Exercise + Intermittent Fasting. While there was no intervention in the healthy and obese control groups, the other groups followed predetermined exercise and diet programs for 6 weeks. Blood samples were taken from the participants in the research group twice (before and after the interventions). An autoanalyzer was used to determine the lipid profile in the blood samples taken, and the ELISA method was used to analyze other parameters. Results: Overall, a significant difference was found in the values of weight, BMI, subfatin, ghrelin, leptin, cholesterol, triglyceride, HDL and LDL as a result of the exercise and diet interventions (p < 0.05). There was no significant difference in asprosin and irisin values (p > 0.05). Conclusions: In conclusion, regular exercise and dietary interventions in obese women can regulate lipid profile, ghrelin, leptin and asprosin levels, and increasing irisin with exercise can activate lipid metabolism and support positive changes in lean mass.

Etli, Serkan; Yılmaz, Tekin; Hansu, Osman
This study concentrated to investigate the influences of white-Portland cement (W-PC) containing silica fume (SF: micro-silica (µSi) and nano-silica (nSi)) as replacement (2–4 wt%) on mechanical (strength and durability), physical and microstructural behaviors of self-compacting mortars (SCMs) fabricated at 0.48–0.63 w/b ratios. In keeping with these purposes, besides of carrying out the workability (mini-slump flow: M−SF and V-funnel: V-F) experiments of SCMs, the mechanical and microstructural tests implemented were: unconfined compressive strength (UCS), flexural strength (FS), freeze–thaw (F-T) and scanning electron microscope (SEM) analysis. The outcomes displayed that, in comparison with the control, replacing W-PC by SF (particularly nSi) enhanced the UCS and FS, resisted against F-T durability by lowering the strength losses in UCS and FS. The ameliorated microstructure resulting in a reduction in the number and/or a narrowing in the size of micro-cracks and pores contributed to generate a more compact and consolidated SCM structure for the improving of strength and durability due of pore-filling effect and superior pozzolanic characteristics of µSi and especially nSi, this in turn reduced the permeability of SCM, which has a significant effect on the strength and durability behaviors of the SCM.

In this study, phylogenetic analysis of Turkish endemic Bornmuellera (Brassicaceae) species was conducted based on nuclear ribosomal DNA (ITS) and chloroplast DNA (trnL intron, trnL-F, rbcL and trnQ-rps16 DNA) sequences. In addition, the relationships between the sequences of some Brassicaceae family species retrieved from NCBI, and Bornmuellera species were documented. All of the plant specimens were collected from different regions of Türkiye, and brought to the laboratory. Total genomic DNA was extracted using the GeneMark kit. After polymerase chain reaction (PCR) analyses, DNA sequences obtained were then edited using Sequencher 5.4, Bioedit 7.2.3 and FinchTV 1.4.0, and analyzed using MEGA 6.0 software. Maximum likelihood (ML) and bootstrap trees were constructed in order to identify the relationships among Bornmuellera species. In the study, the highest nucleotide diversity was detected by rps16-trnQ (0.039146) sequence analysis, while the lowest was detected by rbcL (0.004186) sequence analysis. In addition, according to the phylogenetic analysis results obtained with other Brassicaceae species, it is revealed that the Turkish endemic Bornmuellera genus is monophyletic.

Artuğer, Fırat
Substitution boxes are very important for cryptographic structures. But getting an 8-bit strong s-box is a difficult problem. To address this problem, a new approach is proposed in this study. DNA chains are used in the proposed approach. First of all, a weak s-box is obtained with the help of a chaotic map. Then, a DNA chain is formed with the same chaotic map. In this study, 2000-long DNA chains were produced. Then, two random values consisting of four components are determined from these DNA chains, and these values are addressed to the s-box structure. By changing the places of these values, the s-box structure is improved up to a certain iteration. In this study, 10,000 iterations were examined, and three different strong s-boxes were obtained by using three different DNA chains. The nonlinearity values of these s-box structures were observed as 110.25, 110.5, and 110.75, respectively. The proposed study has proven to work effectively with effective results in three different chains. In addition, it has been proven as a result of the analysis that the proposed s-box structures also have other cryptographic features. The proposed algorithm has surpassed many s-box generation philosophies in the literature. In addition, the proposed algorithm will provide serious gains to cryptographic structures that will be developed in the future.

Heavy metals and their toxicity are a major global concern. They are one of the major environmental problems causing serious problems for living beings. In this study, the adsorption properties of a clay sample located in nature are improved by treating with different materials, and then adsorption properties are examined. It is observed that clay sample can be used in many adsorption applications, including the adsorption of heavy metals such as copper. The clay mineral used in the study was obtained from a rhyolite type rock. Rhyolite rocks, one of the degradation products of volcanic rocks, are the volcanic counterparts of granite. In this study, rhyolite rock was crushed with suitable crushers and grinders, then sieved under 200 mesh with molecular sieve and clay minerals were obtained. The clay samples (K1,K2. K8) were synthesized by subjecting clay with acid and base. Adsorption properties of clay are due to wide surface area, surface functional groups and microporosity. Adsorption of methylene blue and iodine, adsorption from aqueous solutions of copper are done with clay samples and results were compared with samples of clay have not undergone any pre-treatment. In the study, the highest adsorption capacity was determined by applying the Freundlich isotherm. In the K6 sample treated with a base, the highest adsorption capacity was calculated as 26.98 Lg−1. In contrast, the Langmuir isotherm results were calculated in the range of 10.56 to 11.86 Lg−1. This indicates that the adsorption takes place on a heterogeneous surface. The structure and surface properties of clay were examined.

Seasonal Respiratory Diseases (SRDs) usually produce a heightened number of Emergency Department (ED) attendances due to their rapid dissemination within the community and the ineffective prevention measures. Such a context requires effective management of the emergency care processes to provide in-time diagnosis and treatment to infected patients. Nonetheless, EDs have evidenced severe operational deficiencies during these periods, thereby provoking extended bed waiting times in Hospitalization Departments (HDs). Therefore, this paper presents a hybrid approach merging Artificial Intelligence (AI) and Discrete-Event Simulation (DES) to shorten the bed waiting times in HDs considering patient records collated in the first emergency care stages. First, we implemented Random Forest (RF) to estimate the probability of respiratory worsening based on sociodemographic and clinical patient data. Second, we inserted these probabilities into a DES model mimicking the emergency care from the admission to the HD. We then pretested different HD configurations and strategies seeking to reduce the HD bed waiting time. A case study of a European hospital group was used to validate the suggested framework. The AI-DES model enabled decision-makers to identify an improvement proposal with hospitalization bed waiting time lessening, oscillating between 7.93 and 7.98 h.
