(Springer Heidelberg, 2024) Asker, Mehmet Emin; Güngör, Mustafa; Gungor, Mustafa; 18.04. Department of Electricity / Elektrik Bölümü; 18. Vocational Higher School of Midyat/ Midyat Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Hyperspectral image classification is crucial for a wide range of applications, including environmental monitoring, precision agriculture, and mining, due to its ability to capture detailed spectral information across numerous wavelengths. However, the high dimensionality and complex spatial-spectral relationships in hyperspectral data pose significant challenges. Deep learning, particularly Convolutional Neural Networks (CNNs), has shown remarkable success in automatically extracting relevant features from high-dimensional data, making them well-suited for handling the intricate spatial-spectral relationships in hyperspectral images.This study presents a hybrid approach for hyperspectral image classification, combining 3D Depthwise Separable Convolution (3D DSC) and Depthwise Squeeze-and-Excitation Network (DSENet). The 3D DSC efficiently captures spatial-spectral features, reducing computational complexity while preserving essential information. The DSENet further refines these features by applying channel-wise attention, enhancing the model's ability to focus on the most informative features. To assess the performance of the proposed hybrid model, extensive experimental studies were carried out on four commonly utilized HSI datasets, namely HyRANK-Loukia and WHU-Hi (including HongHu, HanChuan, and LongKou). As a result of the experimental studies, the HyRANK-Loukia achieved an accuracy of 90.9%, marking an 8.86% increase compared to its previous highest accuracy. Similarly, for the WHU-Hi datasets, HongHu achieved an accuracy of 97.49%, reflecting a 2.11% improvement over its previous highest accuracy; HanChuan achieved an accuracy of 97.49%, showing a 2.4% improvement; and LongKou achieved an accuracy of 99.79%, providing a 0.15% improvement compared to its previous highest accuracy. Comparative analysis highlights the superiority of the proposed model, emphasizing improved classification accuracy with lower computational costs.

Cancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.

Air pollution poses a critical challenge to environmental sustainability, public health, and urban planning. Accurate air quality prediction is essential for devising effective management strategies and early warning systems. This study utilized a dataset comprising hourly measurements of pollutants such as PM2.5, NOx, CO, and benzene, sourced from five metal oxide sensors and a certified analyzer in a polluted urban area, totaling 9,357 records collected over one year (March 2004-February 2005) from the Kaggle Air Quality Data Set. A comprehensive comparison of ten machine learning regression models XGBoost, LightGBM, Random Forest, Gradient Boosting, CatBoost, Support Vector Regression (SVR) with Bayesian Optimization, Decision Tree, K-Nearest Neighbors (KNN), Elastic Net, and Bayesian Ridge was conducted. Model performance was enhanced through Bayesian optimization and randomized cross-validation, with stacking employed to leverage the strengths of base models. Experimental results showed that hyperparameter optimization and ensemble strategies significantly improved accuracy, with the SVR model optimized via Bayesian optimization achieving the highest performance: an R2 score of 99.94%, MAE of 0.0120, and MSE of 0.0005. These findings underscore the methodology's efficacy in precisely capturing the spatial and temporal dynamics of air pollution.

Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes
(2017) Aktaş, Hüsnü; Baloch, Faheem Shehzad; 16.02. Department of Seed Production / Tohumculuk Teknolojisi Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The present study was conducted to evaluate the genotype × environment interaction of the yield and quality traits for five bread wheat varieties commonly grown in the Southeastern Anatolia Region of Turkey and 20 advanced lines developed within the framework of the International Winter Wheat Improvement Project. We also determined the allelic pattern of the Glu-1 and Glu-3 loci of these genotypes and examined whether these loci had an effect on the quality traits. There was a significant variation among the genotypes and environments in terms of grain yield, protein content, sedimentation volume (SV), and the extensograph dough energy value (EDEV). The results of the study indicated that genotypic effect was more influential on SV and EDEV than environmental effect; thus, both traits could be used in breeding programs to develop elite cultivars with better quality. Twelve different high-molecularweight (HMW) glutenin alleles were identified at the Glu-A1, Glu-B1, and Glu-D1 loci, resulting in 14 allelic combinations, and 17 different alleles were observed in 19 combinations for low-molecular-weight (LMW) subunits. Furthermore, among all the genotypes, 13 + 16 and 13 + 19 alleles at Glu-B1 and 5 + 12 at Glu-D1 were observed to have the lowest frequency. Our study indicated that the combinations of HMW glutenin alleles with 2* at Glu-A1, 17 + 18 and 13 + 16 at Glu-B1, and 5 + 10 at Glu-D1, as well as the combinations of LMW alleles with subunits c and d at Glu-A3; subunits d, b, c, and g at Glu-B3; and subunits a and b at Glu-D3 had positive effects on the quality traits.

An analysis of age-standardized suicide rates in Muslim-majority countries in 2000-2019
(BMC Public Health, 2022) Zeyrek Rıos, Emek Yüce; Bob Lew; Lester, David; Kõlves, Kairi; Yip, Paul S. F.; Ibrahim, Norhayati; 02.10. Department of Psychology / Psikoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Background: This study examines the 20-year trend of suicide in 46 Muslim-majority countries throughout the world and compares their suicide rates and trends with the global average. Ecological-level associations between the proportion of the Muslim population, the age-standardized suicide rates, male-to-female suicide rate ratio, and the Human Development Index (HDI) in 2019 were examined. Methods: Age-standardized suicide rates were extracted from the WHO Global Health Estimates database for the period between 2000 and 2019. The rates in each country were compared with the age-standardized global average during the past 20 years. The countries were further grouped according to their regions/sub-regions to calculate the regional and sub-regional weighted age-standardized suicide rates involving Muslim-majority countries. Correlation analyses were conducted between the proportion of Muslims, age-standardized suicide rate, male: female suicide rate ratio, and the HDI in all countries. Joinpoint regression was used to analyze the age-standardized suicide rates in 2000-2019. Results: The 46 countries retained for analysis included an estimated 1.39 billion Muslims from a total worldwide Muslim population of 1.57 billion. Of these countries, eleven (23.9%) had an age-standardized suicide rate above the global average in 2019. In terms of regional/sub-regional suicide rates, Muslim-majority countries in the Sub-Saharan region recorded the highest weighted average age-standardized suicide rate of 10.02/100,000 population, and Southeastern Asia recorded the lowest rate (2.58/100,000 population). There were significant correlations between the Muslim population proportion and male-to-female rate ratios (r=-0.324, p=0.028), HDI index and age-standardized suicide rates (r=-0.506, p<0.001), and HDI index and male-to-female rate ratios (r=0.503, p<0.001) in 2019. Joinpoint analysis revealed that seven Muslim-majority countries (15.2%) recorded an increase in the average annual percentage change regarding age-standardized suicide rates during 2000-2019. Conclusions: Most Muslim-majority countries had lower age-standardized suicide rates than the global average, which might reflect religious belief and practice or due to Muslim laws in their judicial and social structure which may lead to underreporting. This finding needs further in-depth country and region-specific study with regard to its implication for public policy.

Animals and pastoral groups in the mountainous Ömerli district of Southeast Anatolia
(Taylor and Francis Ltd., 2020) Sıddıq, Abu Bakar; Şanlı, Süleyman; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Southeast Anatolia has been an ideal place for pastoralism since the Neolithic period. However, there is a lack of information on human–animal relationships from both archaeological settlements and contemporary societies in the region. Through ethnographic fieldwork and exploratory case studies in the mountainous Ömerli district, we explored the dependency and complex relationships between pastoral groups and various animal species in Southeast Anatolia. The case studies revealed affectionate and emotional bonds between shepherds and some individuals of domestic herds, similar to pet–human relationships in urban societies. Shepherds gave human names to certain animals; sometimes these were the names of their close friends or the names of their own children. Grief and prolonged grief was also common among Ömerli shepherds following the loss, death, or sale of these emotionally bonded animals. It was further observed that a single species (domestic or wild) often had complex and multi-purpose relationships with shepherd groups. While tortoises and hares, for instance, were used as sources of meat, the bone, blood, intestine, skin, and shell of these species were often used in traditional medicine. Although pastoral groups are completely dependent on domestic herds for their basic subsistence, Ömerli shepherds were observed to be regular hunters. It appears that the economic benefits were not the only promoters for pastoral subsistence in the study area; compassion and emotional affection for particular animals also reinforced enthusiasm for the practice. Therefore, it can be argued that the data obtained from pastoral villages in the mountainous Ömerli district help us understand interactions and relationships between humans and nonhuman animals in pastoral societies of Southeast Anatolia.

Antibiotics are among the most critical environmental pollutant drug groups. Adsorption is one of the methods used to eliminate these pollutants. In this study, activated carbon was produced from pumpkin seed shells and subsequently modified with KOH. The adsorbent obtained through this procedure was used to remove ciprofloxacin from aqueous systems. Fourier Transform-Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), elemental, X-ray Photoelectron Spectroscopy (XPS), Brunauer–Emmett–Teller (BET) and Zeta analyses were used to characterize the adsorbent. The surface area, in particular, was found to be a very remarkable value of 2730 m2/g. The conditions of the adsorption experiments were optimized based on interaction time, adsorbent amount, pH and temperature. Over 99% success was achieved in removal operations carried out under the most optimal conditions, with an absorption capacity of 884.9 mg·g−1. In addition, the Langmuir isotherm was determined to be the most suitable model for the adsorption interaction

RationaleAdolescent depression is often linked to biological changes associated with stress. However, new approaches and treatment strategies for early intervention and prevention of depression in children and adolescents are still limited. Ashwagandha is an Ayurvedic herb widely used in the management of anxiety and stress. However, there is no information in the current literature on its potential effect on adolescent depression.ObjectivesThis study aimed to investigate the effects of depression on proapoptotic proteins and neuroinflammation and the antidepressant effect of Ashwagandha on depression-like symptoms in adolescent rats exposed to the Chronic Unpredictable Mild Stress (CUMS) model.MethodsIn the study, CUMS model was used to induce depression in adolescent rats. Rats were treated with Ashwagandha or Sertraline. To evaluate the antidepressant effects, behavioral tests as well as biochemical and histological analyses were performed. Forced Swim Test (FST), Sucrose Test and Elevated Plus Maze Test were performed as behavioral tests. Brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) were measured by the ELISA method in the fronto-parietal cortex. Proapoptotic proteins (Bax and Caspase-3) and inflammatory markers (TNF-alpha and IL-1 beta), as well as glial fibrillary acidic protein (GFAP), were evaluated immunohistochemically in the fronto-parietal cortex.ResultsProapoptotic proteins (Bax and Caspase-3) and inflammatory markers (TNF-alpha and IL-1 beta) were increased in the CUMS group. BDNF and GFAP levels were decreased. Ashwagandha treatment was more effective than Sertraline in reducing the levels of these proteins and markers. Additionally, Ashwagandha prevented weight loss.ConclusionsAshwagandha showed antidepressant-like effects in adolescent rats, reducing apoptosis, inflammation, and neuroinflammation, suggesting potential for treating adolescent depression.

Background/Objectives: Cerebral palsy (CP) is a motor disorder resulting from brain damage that is common in childhood. Iron is vital for the body's basic functions. Iron metabolism disorders and inflammation contribute to the neurological complications seen in CP. The purpose of this research was to ascertain the association and correlation between markers of inflammation and iron metabolism in children with CP. Methods: A total of 181 children diagnosed with CP and 111 typically developing children were retrospectively included in the study. Demographic data, blood parameters, C-reactive protein, iron, total iron binding capacity, and inflammation markers were evaluated. Results: C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and systemic immuno-inflammatory index (SII) levels of CP children were found to be statistically significantly higher than those of control group children (p < 0.05). Iron (Fe) and ferritin levels were lower in the CP group, while total iron binding capacity (TIBC) was higher. Spearman correlation analysis showed significant correlations between iron, ferritin and TIBC and SII. Conclusions: Iron deficiency and chronic inflammation are associated with the pathophysiology of CP in patients with CP, and therefore it is important to monitor markers of iron metabolism and inflammation in these patients.

Assessment of Walnut (juglans Regia L.) Cultivation Land Suitability Using a Multiple-Criteria Decision-Making Method in Southeastern Turkey
(Nature Portfolio, 2025) Mercan, Çağrı; 17.06. Department of Architecture and Urban Planning / Mimarlık ve Şehir Planma Bölümü; 17. Vocational Higher School / Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Site selection for agricultural products is critical for agricultural planning, productivity, and farmers. Site selection is also critical for agricultural sustainability, as it helps ensure the efficient use of natural resources and avoids environmental degradation. This research proposes an evaluation model for walnut cultivation in the Savur (Mardin, Turkey) district in the Southeastern Anatolia region. Based on literature data, expert opinion, and local walnut producers' perspectives, a spatial decision support system was developed using Geographic Information System (GIS)-based Multi-Criteria Decision Analysis (MCDA). This model provides farmers and stakeholders with a comprehensive evaluation of the different walnut-producing sites in the Savur district. It allows them to make informed decisions about the most suitable areas for walnut production. The land suitability assessment for walnut orchards included four primary evaluation aspects, ten main criteria, and forty-seven sub-criteria. Evaluation criteria were weighted using the Analytic Hierarchy Process (AHP). A land suitability map was created using the weighted overlay method in overlap with the evaluation criteria. The results showed 442.56 ha of very highly suitable land, 9789.43 ha of highly suitable land, and 1140.76 ha of moderately suitable land in the Savur district. In order to determine the accuracy of the study model, ROC (Receiver Operating Characteristic) analysis was conducted. As a result of the validation analysis, the constructed model had an Area Under the Curve (AUC) of 0.911, which indicates an excellent fit between the model and reality; therefore, the model is acceptable. This study demonstrates that integrating AHP and GIS can aid agricultural land use planning and decision-making.
The Association Between Self-Esteem and Physical Aggression in Elementary School Students in Türkiye: the Role of Being a Victim as Mediator

Childhood and early adolescence play a crucial role in shaping individuals' attitudes and behaviours through the cultivation of self-esteem. While this dynamic may differ among various age groups, self-esteem is anticipated to serve as a protective factor against peer bullying and aggression, particularly within the school setting. The present study aimed to explore the associations between self-esteem, experiences of victimisation, and engagement in physical aggression. This research, structured as a cross-sectional quantitative inquiry, involved administering an online survey to 445 primary and middle school students in T & uuml;rkiye. Descriptive and correlation analysis was performed with the SPSS 22.0 program, and mediation analysis was performed with the IBM AMOS 24 program. Being a victim was found to have a mediating effect on the relationship between self-esteem and physical aggression. Self-esteem reduces physical aggression by reducing being a victim. In this context, educators and policymakers need to focus their efforts to increase self-esteem while developing programs to prevent peer bullying and aggression in schools.

Lung cancer is the most common cause of cancer-related mortality globally. Early diagnosis of this highly fatal and prevalent disease can significantly improve survival rates and prevent its progression. Computed tomography (CT) is the gold standard imaging modality for lung cancer diagnosis, offering critical insights into the assessment of lung nodules. We present a hybrid deep learning model that integrates Convolutional Neural Networks (CNNs) with Vision Transformers (ViTs). By optimizing and integrating grid and block attention mechanisms with InceptionNeXt blocks, the proposed model effectively captures both fine-grained and large-scale features in CT images. This comprehensive approach enables the model not only to differentiate between malignant and benign nodules but also to identify specific cancer subtypes such as adenocarcinoma, large cell carcinoma, and squamous cell carcinoma. The use of InceptionNeXt blocks facilitates multi-scale feature processing, making the model particularly effective for complex and diverse lung nodule patterns. Similarly, including grid attention improves the model's capacity to identify spatial relationships across different sections of the picture, whereas block attention focuses on capturing hierarchical and contextual information, allowing for precise identification and categorization of lung nodules. To ensure robustness and generalizability, the model was trained and validated using two public datasets, Chest CT and IQ-OTH/NCCD, employing transfer learning and pre-processing techniques to improve detection accuracy. The proposed model achieved an impressive accuracy of 99.54% on the IQ-OTH/NCCD dataset and 98.41% on the Chest CT dataset, outperforming state-of-the-art CNN-based and ViT-based methods. With only 18.1 million parameters, the model provides a lightweight yet powerful solution for early lung cancer detection, potentially improving clinical outcomes and increasing patient survival rates.

Synthesis of two phosphinite ligands based on β-amino alcohols, in high yields has been demonstrated. When we treated [Ru(arene)(μ-Cl)Cl]2 {arene:p-cymene,benzene} with chelating phosphinite ligands, we obtained neutral Ru(II)-complexes possessing the general formula [Ru(arene)phosphiniteCl2]. The structure of the ligands and complexes was confirmed using analytical and spectroscopic techniques. The quantum chemical calculations were carried out for the ruthenium complexes at the DFT/CAM-B3LYP level of theory in gas phase. The phosphinite complexes were subjected to cyclic voltammetry studies in order to determine the energies of HOMO and LUMO levels and to estimate their electrochemical and some electronic properties. Organic complex-based memory substrates were immobilized using TiO2-modified ITO electrodes, and the memory functions of phosphinite-based organic complexes were verified by chronoamperometry (CA) and open-circuit potential amperometry (OCPA). In the present study, the antioxidant potentials of ruthenium-based p-cymene and benzene complexes through DPPH radical scavenging, metal chelating, and reducing power activities were also determined. In addition, DNA binding abilities and antimicrobial activities of these complexes against pathogenic bacteria were studied. Finally, the ruthenium complex, (2S)-1-{[(2S)-2-[(diphenylphosphanyl)oxy]propyl][(1R)-1-phenylethyl]amino}propan-2-yldiphenyl phosphinitobis[dichloro(η6-benzene)ruthenium(II)] also catalyzed asymmetric transfer hydrogenation of acetophenone with high conversion (up to 99%) and good enantioselectivity (ee up to 89 %), in the existence of formic acid and triethylamine in dichloromethane medium under air atmosphere.

This study aims to design multidisciplinary bioagents for a wide range of biological applications. The synthesis and characterization of 4,5-bis((4-phenylthiazol-2-yl)thio)phthalonitrile (a) and its octa-substituted zinc(II) phthalocyanine derivative (b) were described in this study. Additionally, gold nanoparticles were synthesized in three different sizes, including 10 nm (1), 45 nm (2), and 80 nm (3). Macromolecule (b) was used for surficial functionalization of gold nanoparticles (1-3) to prepare nanoconjugates (1-3b). Antioxidant, antimicrobial, antibacterial, antibiofilm, antidiabetic, and deoxyribonucleic acid (DNA) cleavage activities of biocandidates (b, 1-3, and 1-3b) were examined to determine the optimum size of gold nanoparticles and the effect of modifying groups on their bioactivity in this study for the first time. The highest antioxidant activities were obtained for biocandidates (b and 1b) at 100 mg/L. The best minimum inhibitory concentration (MIC) values were obtained at 32 mg/L for bioagents (b, 1, and 3b) against E. faecalis whereas the MIC value was obtained at 32 mg/L for 1b against E. hirae and E. faecalis. Bioagents (b and 1-3b) exhibited high APDT activities (16 mg/L) against the studied microorganisms. The highest biofilm inhibition activities were obtained 94.57 and 89.28% for 50 mg/L nanoconjugate (1b) against S. aureus and P. aeruginosa, respectively. All the studied biocandidates inhibited 100% E. coli viability at 50 mg/L. The antidiabetic activities of biocandidates (b, 1-3, and 1-3b) were obtained between 7.52 and 100 mg/L. Bioagents (2, 3, 1b, and 2b) destroyed the DNA integrity, as well. The significant improvement in the biological activities of gold nanoparticles confirmed that new nanoconjugates especially 1b can be considered promising medical nanomaterials after further clinical investigation.

Metallic nanoparticle biosynthesis is thought to offer opportunities for a wide range of biological uses. The green process of turning biological waste into utilizable products gaining attention due to its economical and eco-friendly approach in recent years. This study reported the ability of Solanum tuberosum (ST) peel extract to the green synthesis of non-toxic, stable, small-sized silver nanoparticles without any toxic reducing agent utilizing the phytochemical components present in its structure. UV-visible spectroscopy, X-ray diffraction analysis, Fourier transform infrared spectroscopy, flourier scanning electron microscopy, atomic force microscopy, transmission electron microscopy, and energy dispersive analysis X-ray confirmed the biosynthesis and char-acterization of silver nanoparticles. Also, dynamic light scattering and thermogravimetric ana-lyses showed stable synthesized nanoparticles. The antibacterial activity of the biosynthesized silver nanoparticles was evaluated against four different bacterial strains, Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), Staphylococcus aureus (S. aureus) Bacillus subtilis (B. subtilis), and a yeast, Candida albicans (C. albicans) using the minimum inhibitory concen-tration technique. The cytotoxic activities were determined against Human dermal fibroblast (HDF), glioblastoma (U118), colorectal adenocarcinoma (CaCo-2), and human ovarian (Skov-3) cell lines cancer cells using MTT test. The nanoparticle capping agents that could be involved in the reduction of silver ions to Ag NPs and their stabilization was identified using FTIR. Nano -particles were spherical in shape and had a size ranging from 3.91 to 27.07 nm, showed crys-talline nature, good stability (-31.3 mV), and the presence of capping agents. ST-Ag NPs significantly decreased the growth of bacterial strains after treatment. The in vitro analysis showed that the ST-Ag NPs demonstrated dose-dependent cytotoxicity against cell lines. Based on the data, it is feasible to infer that biogenic Ag NPs were capped with functional groups and demonstrated considerable potential as antibacterial and anticancer agents for biomedical and industrial applications.

Bodily boundaries transgressed: corporal alteration through ornamentation in the Pre-Pottery Neolithic at Boncuklu Tarla, Türkiye
(Cambridge Univ Press, 2024) Kodaş, Ergül; Baysal, Emma L.; Ozkan, Kazim; 02.03. Department of Archaeology / Arkeoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Lack of contextual evidence for the use of small personal ornaments means that much of our understanding of ornamentation traditions within archaeological cultures is reconstructed from ethnographic comparisons. New in situ finds from the areas around the ears and mouth in burials at Boncuklu Tarla, a Neolithic settlement in Turkiye, add a novel dimension to the interpretation of stone 'tokens' or 'plugs'. This article presents a new typology for these artefacts and argues for their use as ear ornaments or labrets in a practice involving significant and lasting corporal alteration.
Boncuklu Tarla: Production and Social Dynamics of a Middle PPNB Knapped Stone Workshop (Mardin/Türkiye)
(Routledge Journals, Taylor & Francis Ltd, 2025) Kodaş, Ergül; Kodas, Ergul; 02.03. Department of Archaeology / Arkeoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Boncuklu Tarla, located about 2 kilometres west of the Tigris River, is one of the few sites continuously occupied throughout the entire Pre-Pottery Neolithic Period. This site offers key insights into the evolving techniques and typologies of knapped stone tool production during the Neolithisation process. In 2017, excavations revealed a knapped stone workshop on the floor of a domestic structure, dated to the Middle PPNB. A total of 2,067 artefacts-including cores, flakes, debris, and unprocessed raw material-were found in situ, stacked together. Of these, 1,564 pieces are flint and 503 are obsidian. The finds are especially significant for understanding the use of pressure flaking techniques. Detailed typological and technological analyses, supported by experimental studies, have helped reconstruct all stages of the cha & icirc;ne op & eacute;ratoire in this production context. The Boncuklu Tarla assemblage contributes important data on Neolithic craft specialization and the organization of lithic production within domestic spaces.
