First report of Neoscytalidium novaehollandiae on common sage (Salvia officinalis)
(Springer link, 2021) Dervis, Sibel; Guney, Inci Guler; Kosar, Islim; Bozoglu, Tugba; Ozer, Goksel
In June 2020, many plants exhibited symptoms of root rot and foliar blight in the experimental field of common sage in Sanliurfa province, Turkey. The pathogen was identified as Neoscytalidium novaehollandiae based on morphological characteristics and phylogenetic analysis of partial sequence of the transcription elongation factor 1-alpha gene and the internal transcribed spacer of rDNA. Koch's postulates were fulfilled by successful re-isolation of the pathogen from inoculated plants in the pathogenicity assay. To our best knowledge, this is the first report of N. novaehollandiae causing root rot and foliar blight of common sage worldwide.

Evaluation of Breastfeeding Behaviors and Complementary Feeding Practices of Turkish and Syrian Refugee Mothers
(Soc Argentina Pediatria, 2023) Orhan, Ozhan; Elci, Huseyin
Objectives: The purpose of this study was to compare breastfeeding and related factors (age, level of education, age at first pregnancy, etc.), and complementary feeding practices between Syrian refugee and native Turkish mothers.Material and methods: This descriptive-comparative study examined the nutritional characteristics of infants aged 9 to 60 months whose mothers were Turkish or Syrian refugees who attended Kiziltepe Results: 204 mothers (126 Turkish and 78 Syrian) who had a child aged 9-60 months were included. The average age of the mothers was 27.60 & PLUSMN; 5.17 years for Turkish citizens and 28.91 & PLUSMN; 5.62 for Syrian refugees, without significant difference between the two groups (p: 0.091). Postpartum breastfeeding was 91.3% and breastfeeding duration was 12 (0-24) months in Turkish citizens; in Syrian refugees, breastfeeding was 84.6% and average breastfeeding time was 9 (0- 24) months (respectively, breast milk intake p: 0.144, uptake time p: 0.161; no statistical difference). Breastfeeding training was received by 23.8% of Turkish citizens and 5.1% of Syrian refugees; there was a significant difference between the two groups (p: 0.001).Conclusion: In refugee groups, infant and maternal nutrition practices are disrupted. Working in conjunction with local and international organizations and state agencies that give help to refugee groups, the appropriate interventions, initiatives, supports, and awareness-raising activities would strive to improve practices in mother and baby nutrition and narrow gaps.
Automated Mucormycosis Diagnosis from Paranasal CT Using ResNet50 and ConvNeXt Small
(MDPI, 2025) Toprak, Serdar Ferit; Dedeoglu, Serkan; Kozan, Gunay; Ayral, Muhammed; Can, Sermin; Turk, Omer; Akdag, Mehmet
Purpose: Mucormycosis is a life-threatening fungal infection, where rapid diagnosis is critical. We developed a deep learning approach using paranasal computed tomography (CT) images to test whether mucormycosis can be detected automatically, potentially aiding or expediting the diagnostic process that traditionally relies on biopsy. Methods: In this retrospective study, 794 CT images (from patients with mucormycosis, nasal polyps, or normal findings) were analyzed. Images were resized and augmented for training. Two transfer learning models (ResNet50 and ConvNeXt Small) were fine-tuned to classify images into the three categories. We employed a 70/30 train-test split (with five-fold cross-validation) and evaluated performance using accuracy, precision, recall, F1-score, and confusion matrices. Results: The ConvNeXt Small model achieved 100% accuracy on the test set (precision/recall/F1-score = 1.00 for all classes), while ResNet50 achieved 99.16% accuracy (precision approximate to 0.99, recall approximate to 0.99). Cross-validation yielded consistent results (ConvNeXt accuracy similar to 99% across folds), indicating no overfitting. An ablation study confirmed the benefit of transfer learning, as training ConvNeXt from scratch led to lower accuracy (similar to 85%) Conclusions: Our findings demonstrate that deep learning models can accurately and non-invasively detect mucormycosis from CT scans, potentially flagging suspected cases for prompt treatment. These models could serve as rapid screening tools to complement standard diagnostic methods (histopathology), although we emphasize that they are adjuncts and not replacements for biopsy. Future work should validate these models on external datasets and investigate their integration into clinical workflows for earlier intervention in mucormycosis.

TRACING HIGHLY ADAPTED STABLE YIELDING BREAD WHEAT (TRITICUM AESTIVUM L.) GENOTYPES FOR GREATLY VARIABLE SOUTH-EASTERN TURKEY
(CORVINUS UNIV BUDAPEST, 2016) Aktas, H.
Wheat (Triticum aestivum L.) is the most widely adapted and cultivated cereal grain in the world. In 2013 cropping season, wheat was harvested on 1.3, 7.8, and 214 million ha in south-eastern Turkey, Turkey and World, respectively. Breeding programs in the Turkey have achieved tremendous gains in grain yield over past two decades. However, yield fluctuated over the years due to change in environmental conditions and genotype by environment interactions. Therefore, this study was conducted with overall objectives to identify high yielding and stable candidate genotypes for release in southeastern Turkey. A total of 25 genotypes with 20 advanced experimental lines and five check cultivars were planted at 10 locations in south-eastern Turkey in 2010-11 cropping season. Grain yield stability was determined using Eberhart and Russel, AMMI and GGE-biplot methods. Based on these results G1, G12, G13 and G19 were identified as the potential candidate genotypes for release. GGE-biplot classified south-eastern Turkey into two mega-environments. AMMI and GGE biplot explained 86.49% and 86.43% of the total variation for grain yield, respectively. These result suggested that all three methods were equally efficient in determining the stability of the genotype. However, the GGE biplot methodology is more preferred than AMMI and Eberhart and Russel because it facilitates clearly visualize which-won-where pattern and the discriminating ability of environments.

Theoretical and experimental investigations on corrosion control of mild steel in hydrochloric acid solution by 4-aminothiophenol
(EMERALD GROUP PUBLISHING LTD, 2019) Yildiz, Resit; Mert, Basak Dogru
Purpose This paper aims to study inhibitory effect of 4-aminothiophenol on the corrosion of mild steel (MS) in 0.5 M HCl. Design/methodology/approach In this study, electrochemical experiments, quantum chemical calculations, potentiodynamic measurements, linear polarization resistance and scanning electron microscopy were used. Findings The experimental results suggest that this compound is efficient corrosion inhibitor and the inhibition efficiencies increase with increasing their (from 0.5 to 10.0 mM.) concentrations. This reveals that inhibitive actions of inhibitors were mainly due to adsorption on mild steel surface. The adsorption of these inhibitors was found to obey Langmuir adsorption model. The computed quantum chemical features show good correlation with empirical inhibition efficiencies. Originality/value The 4-aminothiophenol is suitable inhibitor for application in closed-circuit systems against corrosion. The study is original and has great impact in industrial area. The obtained theoretical results have been adapted with the experimental data.
Evolving Policies of the EU Towards Israeli-Palestinian Conflict: Changing Actor Identities and Geostrategic Interests
(Seta Foundation, 2025) Acar, Necmettin; Kızılkan, Zelal
From the 1980s onwards, the EU took a balanced approach to the Israeli-Palestinian conflict. In the last two decades, the EU has abandoned its role as a normative and neutral player. It appeared to address the Israe- li-Palestinian conflict within the context of security. On this basis, the paper aims to assess changing policies of the EU towards the Israeli-Palestinian conflict since the early 1970s. By revisiting constructivist theories, the study attempts to find out the role of the identities in the EU’s policies toward the Israeli-Palestinian conflict. It concludes that the shift in the identities of the major political actors from the Palestine Liberation Organization to Hamas led to the reformulation of its policy toward Israeli-Palestinian conflict.

(TAYLOR & FRANCIS INC, 2015) Okumus, Veysi; Celik, K. Serdar; Ozdemir, Sadin; Dundar, Abdurrahman; Kilinc, Ersin
The potential biosorption abilities of apple shell (AS), orange peel (OP), banana peel (BP), and millet waste (MW) as a bio-waste material to remove 2,4-dichlorophenoxy acetic acid (2,4-D), 2,4-dichlorophenoxy propanoic acid (2,4-DP), and 2,4-dichlorophenoxy butyric acid (2,4-DB) from aqueous solution were investigated in batch condition. Optimum biosorption conditions were determined as a function of contact time, pH of the solution, amount of biomass, and initial pesticide concentrations. The concentrations of the pesticides in the remaining solutions were simultaneously determined by high performance thin layer chromatography. Langmuir and Freundlich models were applied to describe the biosorption isotherm of the pesticides by agricultural wastes. The experimental adsorption data were fitted to Langmuir adsorption models (r(2)>0.99). It was found that adsorption of 2,4-DP was higher for all biosorbent. The highest maximum adsorption capacities of 2,4-DP were found as 40.08, 22.71, 33.26, and 45.45mg/g, respectively, for AS, OP, BP, and MW. Maximum adsorption capacity was obtained for 2,4-D as OP>MW>BP>AS, 2,4-DP as MW>AS>BP>OP, and 2,4-DB as OP>AS>BP>MW. From the results, it can be said that MW was an effective biosorbent for removal of 2,4-DP and OP was an effective biosorbent for removal of 2,4-D and 2,4-DB through the studied pesticides. Optimum biosorption conditions were determined as 60min of contact time, 100mg of biomass, AS at pH 6.0, OP at pH 6.0, MW at pH 7.0, and BP at pH 7.0. FT-IR was employed to understand the surface properties of biosorbents. According to the results, agricultural wastes have high adsorption capacity.

Political Discourse and Semiotics
(De Gruyter Mouton, 2024) Canakpinar, Betul; Kalelioglu, Murat; Gunay, Veli Dogan
In recent years, semiotics has put "life" at the center of the subject of study. There is the desire to be successful in the lifestyle and the desire to convey the right knowledge to the recipient or the correct use of practices in life. A semiotic theory developed by Jacques Fontanille recently showed that strategy can also be used in semiotic analysis. So, the way of life that Fontanille talks about is not just strategy. The process we call "lifestyle" has an order from small to large: There are basic signs, texts, objects, actants, practices, action phases, strategies, and finally lifestyle. In this study, we question the function of strategy, but generally of productive pursuit, in the analysis of political discourses. In our study, we reveal the approach of semiotics to political discourses that concern the whole world and discuss whether they are valid in every society. We emphasize political semiotics, which is used to understand the general structure of political discourses, and show the general functioning of political discourses with Greimas' Actantial Model. We conclude that politicians can influence target audiences by using various methods and discourse strategies.

Association Between Abo Blood Group, Peripheral Artery Disease Lesion Severity, and Coronary Artery Disease Coexistence
(Elsevier Science Inc, 2025) Evsen, Ali; Aktan, Adem; Kilic, Raif; Ozbek, Mehmet
Background: This study aims to investigate the relationship between ABO blood groups and the severity of peripheral artery disease (PAD) lesions, the coexistence of coronary artery disease (CAD) with PAD, and to identify which blood groups may be more predisposed to these conditions. Methods: This study, which has a single-center and retrospective design, includes 305 patients diagnosed with peripheral artery disease (PAD) between 2015 and 2021. The patients were selected from those with at least 50% stenosis detected by computed tomography (CT) angiography. The severity of PAD lesions was evaluated according to the TransAtlantic Inter-Society Consensus (TASC-II) classification, and the presence of CAD was determined by simultaneous conventional coronary angiography. Demographic data, comorbidities, and laboratory results were collected, and statistical analyses were performed using chi-square tests, logistic regression, and t-tests. All of these patients were divided into 2 groups based on their ABO blood types: O and non-O blood groups. Results: This study demonstrates a significant relationship between blood group classification and both the severity of PAD and the prevalence of CAD. Patients with non-O blood groups exhibited a higher likelihood of having severe PAD lesions (TASC-C and TASC-D) compared to those with O blood groups, who more frequently had milder lesions (TASC-A and TASC-B) (P < 0.001). The prevalence of CAD was also significantly higher among patients with non-O blood groups than those with the O blood group (54.4% vs. 36.4%; P = 0.003). In the logistic regression analysis, non-O blood groups, alongside age, hypertension (HT), and chronic kidney disease (CKD), emerged as independent predictors of severe PAD (P < 0.001 for non-O blood groups). Similarly, older age and non-O blood group status were identified as significant independent predictors of CAD (P = 0.004). These findings suggest that blood group classification, particularly non-O groups, may influence the severity and coexistence of PAD and CAD.
Conclusion: Our study reveals a significant association between ABO blood groups and both the severity of PAD and the association of CAD, and shows that non-O blood groups are linked to more severe forms of these conditions. These findings highlight the potential role of ABO blood groups in cardiovascular risk stratification, suggesting a need for further research to confirm these associations and understand their clinical implications.

Stripe rust resistance gene Yr15 in Turkish and Kazakhstan wheat germplasms and the potential of Turkish wild emmer for stripe rust breeding
(Institute for Ionics, 2023) Baloch, Faheem Shehzad; Ali, Amjad; Tajibayev, Daniyar; Nadeem, Muhammad Azhar; Ölmez, Fatih; Aktaş, Hüsnü; Alsaleh, Ahmad; Cömertpay, Gönül; İmren, Mustafa
Puccinia striiformis f. sp. tritici (Pst) is a devastating obligate fungal biotroph that causes stripe rust disease in wheat in temperate and cooler regions, especially in Kazakhstan and Turkey. Chemical control of Pst is not a sustainable or economic strategy in these countries. Therefore, a suitable alternative to these pesticides, such as the development of resistant wheat cultivars, is needed. During the present investigation, a large set of wheat germplasms was characterized to determine the presence of the broad-spectrum resistance Yr15 gene using Y15K1_F2/uhw30_1R primers. This collection contained 360 accessions including 233 durum and bread wheat collected from KASIB cultivars and advanced lines that were developed by eight breeding programs within the Kazakhstan-Siberia Wheat Improvement Network and Turkey, and 127 wild emmer collected from Turkey only. The positive control was wild emmer IDs WEW 83-1, WEW 84-1, and WEW-85, which previously showed positive amplification of the Yr15 gene with these primers. Yr15, a broad-spectrum R-gene derived from wild emmer wheat encoding a putative kinase-pseudokinase protein designated as wheat tandem kinase 1, comprises a unique R-gene structure in wheat against the yellow (stripe) rust. None of the tested cultivated wheat germplasms from 174 durum wheat of the KASIB Network or 59 of bread wheat from Turkey showed positive amplification, but 89 of 127 (70.07%) wild Triticum dicoccoides showed positive amplification. The collection from the Karacadağ regions showed the maximum number of genotypes (46) with positive amplification for Yr15, followed by Eruh (10), Şırnak (5), Malazgir-Tunceli (4), Tunceli (4), Şırnak-Uludere yol (3), Tunceli-Pülümür (3), and Karacadağ/Kerteş Köyü –Siverek (3). We conclude that wild wheat cultivars are a good source of the Yr15 gene and that introgression of this gene into the cultivated wheat germplasm of both countries should be performed to manage the Pst pathogen in the future

(Research in Educational Administration and Leadership, 2021) Ağalday, Bünyamin; Dağlı, Abidin
The research aims to determine the relationship between public primary school principals' paternalistic leadership behaviours and teachers' organizational creativity and organizational dissent perception levels according to primary school teachers' perceptions. A quantitative correlational design was utilized in the research. The research sample consists of 1059 public primary schoolteachers selected by stratified sampling method in Mardin city center and eight districts of Mardin during the 2016-2017 academic year. The data of the research were obtained by using the "Headmasters' Paternalistic Leadership Behaviours Scale," "Organizational Creativity Scale," and "Organizational Dissent Scale. "The data analysis revealed the following findings: There was a positive and significant correlation between the paternalistic leadership behaviours of primary school administrators and teachers' perceptions toward organizational creativity and organizational dissent. Also, paternalistic leadership behaviours of primary school administrators were found to be a significant predictor of teachers' perceptions toward organizational creativity and organizational dissent. The principals should exhibit benevolent leadership behaviours that enhance the teachers' organizational creativity perceptions, such as endeavouring to create a family milieu in school, being tolerant of teachers, and supporting teachers to take the initiative.

Morphological, Physiological, Molecular, and Pathogenic Insights Into the Characterization of Phytophthora Polonica From a Novel Host, Hazelnut (Corylus Avellana)
(Academic Press Ltd - Elsevier Science Ltd, 2024) Turkkan, Muharrem; Ozer, Goksel; Dervis, Sibel
Hazelnuts, constituting a significant global crop, hold paramount importance in Turkiye, contributing to approximately 71.14 % of the world's hazelnut cultivation area. In the summer of 2023, hazelnut trees in two orchards situated in the Altinordu district of Ordu province, within the Black Sea region of Turkiye, the largest producer and exporter of hazelnuts, exhibited symptoms of decline associated with root rot. Phytophthora sp. was consistently isolated from necrotic taproots, initiating an in-depth study to discern the causal agent behind the observed hazelnut decline. The species was identified as P. polonica by its distinctive morphological traits, including homothallic characteristics, amphigynous or paragynous antheridia, long nonbranching sporangiophores, and nonpapillate sporangia with internal proliferation. Multiple genetic markers (ITS, tub2, and COI) facilitated a clear differentiation of P. polonica from other Phytophthora species within Clade 9, supporting its classification within Subclade 9b. This investigation also evaluated the impact of diverse nutrient media (CA, V8A, and CMA), temperatures, and pH levels on the mycelial growth of P. polonica HPp-1 and HPp-2 isolates. The optimal conditions for maximal mycelial growth were determined through the D-optimal design of the Response Surface Method, revealing the significant influence of all factors on mycelial growth. The identified optimal conditions were at 26.09 degrees C, pH 5.12, with CMA as the nutrient medium. Validation experiments conducted under these optimal conditions unveiled mycelial growth of 7.24 +/- 0.15 mm day(-1) and 6.81 +/- 0.09 mm day(-1) for P. polonica HPp-1 and HPp-2 isolates, respectively, with an error of less than 5 %. Pathogenicity assessments confirmed P. polonica's virulence on hazelnuts, with distinct lesion development observed in twig inoculation, cut stem segments, and foliar tests. While no statistically significant difference was noted in lesion areas between HPp-1 and HPp-2 isolates in twig and stem segment assays, a statistical difference in leaf lesion areas (19.96 +/- 2.04 cm(2) and 9.16 +/- 3.43 cm(2)) emerged in foliar tests after only a 5-day incubation period, indicating their high susceptibility to the pathogen. This study is the first to report P. polonica as a hazelnut pathogen in Turkiye and around the world, highlighting the previously non-existent threat of Phytophthora root rot in hazelnuts, given the substantial lack of scientifically documented cases related to hazelnut root rot diseases. The quadratic model design employed in physiological analyses is reliable for optimizing mycelial growth and can serve as a guiding framework for similar investigations.

Diagnostic Performance of Erythropoietin and Erythropoietin Receptors Levels in Children with Attention Deficit Hyperactivity Disorder
(Clinical Psychopharmacology and Neuroscience, 2021) Güngör, Meltem; Ergul Belge Kurutas, Erkan Oner, Velid Unsal, Hatice Altun, Ali Erdinc Yalin, Serap Yalin, Ozlem Bozkus, Nilfer Sahin
Objective: Attention deficit hyperactivity disorder (ADHD) is a heterogeneous, highly heritable, a common childhood neurobehavioural disorder resulting from complex gene-gene and gene-environment interactions. The erythropoietin (Epo)/erythropoietin receptors (EpoR) system turned out to have additional important functions in nonhematopoietic tissue. In this study, we aimed to investigate the levels of Epo and and EpoR, and also their diagnostic values in children with ADHD. Methods: A total of 70 children were included in the study, 35 drug-naive patients with ADHD (age: 6−12 years; male/female: 20/15) and 35 healthy controls (age: 6−12 years; male/female: 22/13). Serum Epo and EpoR levels was determined using a commercial sandwich enzyme-linked immunosorbent assay kit. Results: The results indicated that the levels of Epo decreased in patients with ADHD compared to control (p < 0.05). On the other hand, EpoR levels increased in these patients (p < 0.05). Furthermore, the ratio of Epo/EpoR was significantly lower in ADHD patients than controls (p < 0.05). Receiver operator characteristic curve analysis showed high diagnostic performance for Epo and EpoR, areas under curve were 0.980 and 1.000, respectively. Conclusion: This is the first report to investigate the association between serum Epo and EpoR levels in ADHD patients. Our results indicated that Epo may play a role in the etiology of ADHD, and Epo therapy may be beneficial in these disorders if given in addition to the routine treatment of children with ADHD. Furthermore, our results reveal possible diagnostic value of Epo and EpoR.

Multiple Hierarchies: Servants and Masters, Monastic Officers, Ordained Monks, and Wearers of the Great and the Small Habit at the Stoudios Monastery (10th – 11th Centuries)
(Slovansky Ustav AV CR, 2016) Krausmüller, D.; Krausmüller, Dırk; 02.14. Department of History / Tarih Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This article analyses the Stoudios Typikon, a monastic rule from the late tenth century. The original is lost but the rule can be reconstructed through comparison of later adaptations. Analysis of the text shows there were three hierarchies within the community of Stoudios: the monastic officials responsible for the administration of the monastery under the oikonomos, the priests and deacons under the protopresbyteros, and the wearers of the great and small habit. The three hierarchies were distinct, but efforts were made to harmonise them to minimise con? ict. Most of the monastic officials seem to have been deacons, and no monk could be ordained priest or deacon if he had not previously been clad in the great habit. The Stoudios Typikon emphasises the role of ordained monks. Only priests were allowed to give blessings. Even the oikonomos had to rely on their services if he was a layman. Moreover, in the church, and possibly also in the refectory, the order of precedence followed the ecclesiastical hierarchy and not the hierarchy of the monastic offices, with the sole exception of the oikonomos. Other Stoudite sources suggest that the stipulations of the Stoudios Typikon were never fully implemented. However, there can be little doubt that these stipulations reflected the views of the ordained members of the community. The latter are also the most likely authors of the text. © 2016, Slovansky Ustav AV CR. All rights reserved.
Genotype Responses of Barley for Crop Adaptability, Yield Variations and Quality Traits under Terminal Heat Stress Conditions
(Pontificia University Catolica Chile, Fac Agronomia ingenieria Forestal, 2025) Elis, Seval; Tanrikulu, Abdulkadir; Yildirim, Mehmet
Genotype Responses of Barley for Crop Adaptability, Yield Variations and Quality Traits under Terminal Heat Stress Conditions. Int. J. Agric. Nat. Resour. 148-163. Barley, a vital crop globally, faces increasing threats from rising temperatures and climate variability. The physiological and morphological characteristics of ten advanced barley lines and two cultivars were assessed in this study over a two-year period under rain-fed conditions. This research revealed significant variations in genotype performance under terminal heat stress. The results highlight that temperature stress exceeded critical thresholds during critical growth stages, impacting grain yield and quality. Genotypes such as 'IBON HI 16-12' displayed consistently high yields, whereas 'Kendal' showed adaptability across varying conditions. The leaf chlorophyll content (SPAD) and normalized difference vegetation index (NDVI) varied among the genotypes, and a high NDVI did not consistently lead to higher yields under heat stress conditions. Quality traits, including protein content, test weight, and thousand-kernel weight, fluctuated independently of yield. Canopeo measurements highlight rapid ground cover growth, emphasizing its importance for plant productivity. Genotypes with delayed heading and prolonged physiological maturity presented high yields under heat stress. Leaf area index (LAI) measurements may aid in the selection of heat-tolerant genotypes. Alternatively, Canopeo measurements at 85-95% coverage provide valuable data for assessing genotype performance. This study enhances our understanding of barley's response to heat stress, emphasizing genotype adaptability and the need for further research to address temperature-related yield variations.

FPGA simulation of chaotic tent map-based S-Box design
(Wiley Online Library, 2022) Türk, Ömer
The chaotic system has a characteristically random behavior by nature, and these systems have their own characteristics in a completely deterministic structure. This feature of a chaotic system makes it difficult to predict encryptions designed based on such a system. Thanks to this unpredictable and strong feature, maps produced from chaotic systems are an important alternative in the field of encryption. One of the structures obtained by employing chaotic maps is the substitution box. S-Box, which provides the confusion principle used in block ciphers, is the main block that dynamically replaces unencrypted data with confidential data and makes a significant contribution to ensuring high security in the encryption system. Therefore, S-Boxes hold a critical role in block ciphers. Speed and reliability are important parameters in the creation of this main block. Especially, applications performed on hardware are more reliable and high performance. Therefore, in this study, an S-Box was designed using fieldprogrammable gate arrays (FPGA) simulation from a chaotic tent map to create a fast and reliable S-Box because FPGAs offer solutions that may be important in this field considering their fast and customizable architecture. In the proposed method, the S-Box was created in 0.16 s. In addition, the dynamic properties of the chaotic tent map were analyzed with Lyapunov exponents, and the NIST SP 800-22 test was applied for the information encryption suitability of the proposed chaotic system. Also, to test the reliability of the produced S-Box structures, SAC, non-linearity, bit independence criteria, and input/output XOR distribution table metrics were implemented. The results showed that the proposed chaotic map was dynamic and passed the reliability tests successfully.

Biosynthesis and Characterization of Silver Nanoparticles Using Fig (ficus Carica) Leaves: a Potential Antimicrobial Activity
(Corvinus Univ Budapest, 2019) Acay, H.
Environmentally friendly methods for obtaining nanomaterials see a great interest. In addition to being inexpensive, the easy implementation process and the advantages of synthesis without toxic chemicals are the main reasons of interest. In this study, silver nanoparticles (AgNPs) were successfully synthesized using fig (Ficus carica) leaf extract. The formation and the presence of AgNPs were observed using ultraviolet-visible spectrophotometry (UV-Vis). Peaks with a maximum wavelength of 419 nm are identified in the measurements. Phytochemicals in the extract responsible for functional groups providing reduction and stability were evaluated using Fourier transform infrared spectroscopy (FT-IR) data. The Scanning electron microscopy-Energy Dispersive X-Ray Spectrum (SEM-EDX) analysis showed that the AgNPs were spherical and the elemental composition contained mostly silver. X-ray diffractometer (XRD) results revealed that the peaks 111 degrees, 200 degrees, 220 degrees and 311 degrees belong to the characteristic structure of silver and have a crystal dimension of 17.30 Nm using Debye-Scherrer equation.
