2023-2024 Excavations at Boğaziye Höyüğü: a Recently Discovered Mound Settlement in the Upper Khabur Region
(Istanbul Univ, 2025) Gene, Bulent; Sahin, Muaviye; Isik, Senem; Abakay, Ayda; Kaya, Semsihan; Konyar, Erkan; Tan, Armagan
Boğaziye Höyük lies at the northwestern end of the vast and fertile Upper Khabur Region, which stretches along the southern foothills of the Kašiari Mountains. Material culture remains unearthed at the mound by two seasons of excavations (2023-2024) shows significant similarities to assemblages known from other Upper Khabur sites. Our excavations in Trenches BE18-BE17 and BF18 on the northern slope of the mound focused on revealing the stratigraphic sequence in this area. Architectural remains of Building Levels I and II and finds from these contexts in Trench BE18 are dateable to the mid-3rd millennium BC. In Trench BE17, Building Level I also revealed finds that can be dated to the 3rd (especially mid-3rd) millennium BC, and in Trench BF18, ceramic sherds dateable to the 3rd millennium BC were found in Building Level III. This article presents new findings from Boğaziye Höyük and discusses their significance in comparison with the results of surveys and excavations in the Upper Khabur Region, which have continued increasingly since the mid-1930s. We evaluate the significance of Boğaziye Höyük as a regional center within the Upper Khabur basin, and we elucidate its habitation sequence and building levels in the light of our recent excavations. Based on a comparative evaluation of its material culture remains within a regional perspective, we contextualize Boğaziye Höyük in relationship to the cultural horizons of the early and mid-3rd millennium BC in the Upper Khabur Valley.

Mardin Artuklu University / Mardin Artuklu Üniversitesi
The aim of this study was to compare targeted and non-targeted drag flick field hockey shooting techniques in the penalty corner area, using a three-dimensional kinematic analysis. Eleven male field hockey players playing in the super league (mean age: 19,82 +/- 1,40 years) participated voluntarily. Seven high-speed cameras (Oqus 7+) with 120Hz refresh rates were used. Field calibration was completed via the wand method. The data were evaluated in two phases: start and finish. Players undertook three drag flick shots to the box using targeted and non-targeted techniques. The angular kinematics and stroke force applied to the stick were analyzed using the Qualisys Track Manager Program V2.12, and ball velocity statistics were gathered with the SPSS 18.0 program. To compare between the targeted and non-targeted shots of the drag flick shooting techniques, t-test was applied. At the drag flick of the players, significant differences were noticed at the angular speed of the right shoulder and the left knee, and the angular acceleration of the right hip in the starting phase, and also at the right hip angular acceleration at the finish phase. When the ball speed data considered, a significant decrease was observed between the targeted and non-targeted drag flick shots. Significant correlation was found out between some variables, at the angular kinematics and both force applied on the stick and the ball speed values (p <= 0.05). In conclusion, to make an accurate target shot the players maximize their targeted shooting rates, particularly by decreasing the speed of their lower extremities.
Ability of Cha2ds2-vasc/R2cha2ds2-vasc Scores To Predict Complications Related To Cardiac Implantable Electronic Devices
(Wiley, 2025) Aktan, Adem; Kilic, Raif; Guzel, Hamdullah; Tastan, Ercan; Oksul, Metin; Guzel, Tuncay; Soner, Serdar
BackgroundGlobally, the number of cardiac implantable electronic devices (CIEDs) is increasing. In our study, we aimed to investigate whether CHA(2)DS(2)-VASc and R(2)CHA(2)DS(2)-VASc scores are predictive of CIED-related complications. MethodsOur investigation was carried out with a multicenter retrospective design. Patients who underwent CIED surgery at two cardiac centers in Turkey between January 2011 and May 2023, 1676, were evaluated. The patients were divided into two groups according to their R(2)CHA(2)DS(2)-VASc scores. Patients with R(2)CHA(2)DS(2)-VASc >= 5 were included in group 1 (380 patients), and patients with R(2)CHA(2)DS(2)-VASc < 5 (1296 patients) were included in group 2. The primary outcome was defined as the cumulative events. Each component of cumulative events, such as hematoma, pericardial effusion, pneumothorax, and infection, was also defined as a secondary outcome. ResultsThe study's patient population had an average age of 62.9 +/- 14 years. Pneumothorax (1.8% vs. 1.3%, p = 0.444), pericardial effusion or tamponade (0.35% vs. 0.2%, p = 0.659), and clinically significant hematoma (1.1% vs. 0.6%, p = 0.376) were comparable between the groups. Infection-related devices and cumulative events classified as primary outcomes were higher in the R(2)CHA(2)DS(2)-VASc >= 5 group (6.1% vs. 1.2%, p < 0.001; 7.6% vs. 3.2%, p < 0.001, respectively). Modeling analyses showed that the CHA(2)DS(2)-VASc score and HT were also independent predictors of device-related infection and cumulative events. ConclusionIn the R(2)CHA(2)DS(2)-VASc >= 5 groups, infection related to the device system and cumulative events were higher. Patients with an R(2)CHA(2)DS(2)-VASc score of 5 or more and a high CHA(2)DS(2)-VASc score should be evaluated more carefully regarding infection and cumulative events before and after the operation.

Abluted capitalism: Ali Shariati's critique of capitalism in his reading of Islamic Economy
(Sage, 2015) Şengül, Serdar; 02.01. Department of Anthropology / Antropoloji Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Islamic sociologist Ali Shariati is a leading figure of the reconstruction of religious thought in the Islamic world known especially for his anti-capitalist stance and leftist reading of Islamic history. In the philosophy of history that he developed, he classified religions as religions of tawheed (unicity of God) and religions of shirk (multiple gods). According to this new reading of history, the main struggle is not between religion and secularism but between religions of tawheed and of sheerk. The issue of the gaining and the distribution of the property is central to his classification. Shariati argued that followers of tawheed and of sheerk can be found in all religions including Islam. To support his argument Shariati explored how capitalistic understanding of Islam has been developed and legalised while anti-capitalist messages and orders of Islam were marginalised and illegalised just after the death of the Prophet Mohammed. He analysed the rivalry between his close companions over the content of a proper Islamic economic order and how this rivalry gave way to two contradicting understanding of Islam, marks of which can be seen today in the contemporary Muslim world. He coined the term abluted capitalism' to define the economic policies of Muslim sovereigns to make Islam compatible with capitalist economic principles.

Acceptance of Diversity, Social Media Use, and Labeling of Refugees in Türkiye: A Mediation Analysis From a Social Work Perspective
(Routledge Journals, Taylor & Francis Ltd, 2025) Aslan, Yavuz; Kocak, Orhan; Kus, Yagmur; Hizmetci, Nimet Sagir
This study examines the relationships between acceptance of diversity, social media use, and the labeling of refugees in T & uuml;rkiye, focusing on the mediating role of social media use. Grounded in Goffman's Labeling Theory and approached from a social work perspective, the study utilized a cross-sectional, correlational design. Data were collected from 431 participants via an online survey. Confirmatory factor analysis and structural equation modeling were employed to analyze the data. The findings revealed that acceptance of diversity was negatively associated with social media use and the labeling of refugees, while social media use was positively associated with refugee labeling. Moreover, social media use mediated the relationship between acceptance of diversity and labeling. These results underscore the dual role of social media as both a space for intercultural communication and a platform for spreading exclusionary narratives. The study contributes to the literature by highlighting the importance of promoting inclusive digital environments. It provides practical implications for developing anti-discriminatory interventions within social work practice and media literacy programs.

(Springer Science and Business Media Deutschland GmbH, 2023) Yiğit, Uğur; Türkkan, Muharrem; İlhan, Hasan; Şimşek, Tuncay; Güler, Ömer; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This study aimed to evaluate the antifungal activity of copper-boron (Cu-B) nanoalloys against a range of Phytophthora species, including P. capsici, P. citrophthora, P. palmivora, P. cinnamomi, P. nicotianae, P. cactorum, P. plurivora, P. inundata, and P. megasperma. The nanoalloys were synthesized via mechanical alloying under an argon atmosphere, resulting in the formation of nanocrystalline Cu-B nanoalloys with irregular morphology and particle sizes ranging from 50 to 240 nm. At a concentration of 250 µg mL−1, the Cu-B nanoalloys demonstrated complete inhibition of mycelial growth, sporangium production, and zoospore germination in all tested Phytophthora species. The EC50 values for mycelial growth ranged from 28.02 to 120.17 µg mL−1, while for sporangium production and zoospore germination, they were below 10 µg mL−1. Furthermore, the nanoalloys exhibited fungicidal activity against specific Phytophthora species, such as P. capsici, P. citrophthora, P. inundata, and P. megasperma, at concentrations of 100, 250, 250, and 250 µg mL−1, respectively. Notably, the Cu-B nanoalloys displayed significant protective and curative effects on tuber rot severity in P. nicotianae-inoculated potatoes, resulting in reductions of 94.13% and 92.61% compared to the control, respectively, at a concentration of 10 µg mL−1 (P < 0.05). These findings highlight the potential of Cu-B nanoalloys as a promising fungicide for the management of plant diseases caused by Phytophthora spp.

(Soc Argentina Pediatria, 2024) Talay, Mehmet N.; Gungor, Emre; Orhan, Ozhan; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

(Springer int Publ Ag, 2017) Cengiz, E. I.; Bayar, A. S.; Kizmaz, V.; Bashan, M.; Satar, A.
Deltamethrin is a pyrethroid pesticide contaminating aquatic ecosystems. The purpose of this study was to clarify the acute toxicity of deltamethrin on the fatty acids of phospholipid (PL) classes in liver and gill of Nile tilapia. The fatty acids of PL classes were analyzed by gas chromatography. Deltamethrin brought about differences in the fatty acids of the PL classes in the liver and gill. In the liver of exposed fish, 16:0, 18:2(n-6), 22:6(n-3) in phosphatidylcholine (PC); 16:0, 18:1(n-9), 18:2(n-6), 20:4(n-6), 22:6(n-3) in phosphatidylethanolamine (PE); 16:0, 18:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) in phosphatidylinositol (PI) and in phosphatidylserine (PS) 16:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) were the affected fatty acids. There were significant alterations in Sigma MUFAs (monounsaturated fatty acids), a(n-3)PUFAs (polyunsaturated fatty acids) and Sigma(n-6)PUFAs in PC; Sigma SFAs (saturated fatty acids), Sigma MUFAs, Sigma PUFAs, Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PE; Sigma SFAs, Sigma MUFAs, Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PI and Sigma SFAs, Sigma MUFAs,Sigma PUFAs and Sigma(n-3)PUFAs in PS. In the gill, 18:2(n-6), 20:4(n-6), 22:6(n-3) in PC; 16:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) in PE; 16:0, 18:0, 18:1(n-9), 18:2(n-6) in PI and in PS 16:0, 18:0,18:1(n-9), 20:3(n-6), 20:5(n-3), 22:6(n-3) affected. The alterations in Sigma SFAs, Sigma MUFAs, Sigma PUFAs and Sigma(n-6)PUFAs in PC; Sigma SFAs, Sigma MUFAs, Sigma PUFAs, Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PE; Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PI; Sigma SFAs, Sigma MUFAs, Sigma PUFAs, Sigma(n-3) PUFAs and Sigma(n-6)PUFAs in PS were significant in gill. The changes in the fatty acids of the PL classes in response to deltamethrin can influence structure and functions of the membrane systems. Changes in fatty acids may be one defense mechanism against the deltamethrin.
Adaptation of the Vicarious Resilience Scale To Turkish: a Validity and Reliability Study
(Educational Publishing Foundation - American Psychological Assoc, 2025) Topcu, Feyza; Boz, Canahmet; Seneldir Patolo, Ayse; Kitapcioglu, Sureyyanur; Isiker-Bedir, Deniz; Sanyar, Sema
Objective: The 27-item Vicarious Resilience Scale (VRS) is the first tool developed to measure vicarious resilience in mental health professionals working with trauma survivors. Given that the VRS measures the positive impact on therapists resulting from observing the healing process of trauma victims, it is especially significant to evaluate its validity and reliability in Turkish culture. This study aims to adapt the VRS to Turkish and examine its psychometric properties. Method: VRS was adapted and administered via electronic survey to 337 mental health professionals from around the globe working with survivors of severe traumas, such as earthquake survivors. The validity of the VRS was examined using different techniques: confirmatory factor analysis (CFA) and criterion-related validity. Result: CFA yielded seven factors that were consistent with the original form: changes in life goals and perspective, client-inspired hope, increased recognition of clients' spirituality as a therapeutic resource, increased capacity for resourcefulness, increased self-awareness and self-care practices, increased consciousness of power and privilege relative to clients' social location, and increased capacity for remaining present while listening to trauma narratives. The Cronbach's alpha reliability of the VRS was found to be .95; it displayed positive correlations with posttraumatic growth, psychological resilience, and quality of life, indicating convergent validity. However, it had a negative correlation with depression, anxiety, and stress, indicating discriminant validity. Conclusion: The VRS is a valid and reliable measurement scale by professionals working with trauma survivors to aid the recognition and cultivation of vicarious resilience in Turkish mental health professionals.

PurposeThis study aims to prevent mild steel (MS) against corrosion in 0.5 M HCl solution, 2-amino-4-methoxy-6-methyl-1,3,5-triazine was used. The effectiveness of the compound as a corrosion inhibitor was studied via electrochemical, surface and theoretical calculation techniques. Design/methodology/approachFor concentrations ranging from 0.5 to 10.0 mM, almost similar polarization resistances were obtained from electrochemical impedance spectroscopy (EIS) and linear polarization resistance tests. It also investigated inhibitive activity of 2-amino-4-methoxy-6-methyl-1,3,5-triazine on the steel surface using scanning electron and atomic force microscope instruments. Langmuir adsorption is the best matched isotherm for the adsorption of the inhibitor to the steel surface. FindingsEIS method was used to determine inhibition efficiency, which was determined to be 95.7% for 10.0 mM inhibitor containing acid solution. Density functional theory's predictions for quantum chemistry agreed well with the other experimental results. Originality/valueThe methods used in this study are effective and applicable; the used organic inhibitor is 2-amino-4-methoxy-6-methyl-1,3,5-triazine; and protective effectiveness is important, which is crucial for the task of MS corrosion prevention.
Adsorption Behaviors of Malachite Green by Using Crosslinked Chitosan/Polyacrylic Acid/Bentonite Composites with Different Ratios
(Elsevier, 2020) Yildirim, Ayfer; Bulut, Yasemin
In this study, by using different quantities of methylenebisacrylamide (MBA) and acrylic acid (AA), chitosan/polyacrylic acid/bentonite composites (CCS/PAA/BNTs) were synthesized and used for the adsorption of malachite green (MG). The fourier transmission infrared spectra, thermogravimetric analysis-differential thermal analysis and scanning electron microscopy techniques were used to determine synthesized composites. The effects of initial concentration, contact time, temperature and pH were investigated. Kinetic studies indicated that, due to the pseudo-second order model, correlation coefficients (R-2 >0.98) were the best fit thus, by using k(ps), the activation energies (E-a) were calculated (19.06, 15.64, 19.49, 8.29, 24.53 kJmol(-1)). The equilibrium data of MG agreed with the Langmuir model. The highest adsorption capacity calculated was found as 384.62-454.55 mgg(-1) for MG adsorption at 298-318 K. Thermodynamic studies demonstrated that MG adsorption was endothermic, caused spontaneous reaction and increased the entropy between 298-318 K. The adsorption reactions of MG were revealed as physisorption (Delta H<80 kJmol(-1)). The optimum pH was found as 6. The CCS/PAA/BNT2 composite indicated the highest adsorption capacity and best thermal stability compared to the other composites. (C) 2019 Elsevier B.V. All rights reserved.

Adsorption of nickel(II) ions from aqueous solutions using Malatya clay: Equilibrium, kinetic, and thermodynamic studies
(Environmental Progress & Sustainable Energy, 2023) Baran, Ayşe; Dal, Mehmet Can; Onursal, Nilgün; Altunkaynak, Yalçın
This paper evaluates Malatya clay (MC) for the removal of Ni(II) ions from aqueous solutions. For adsorption efficiency, the impacts of several factors, such as pH, starting metal ion concentration, and contact duration, were examined. The optimal initial Ni(II) ion concentration was determined to be 5 mg/L, the adsorption contact duration was 360 min, and the solution's pH was 6.27. Using scanning electron microscopy, energy dispersive spectroscopy, and Fourier transform infrared spectroscopy, the surface characteristics of Malatya clay were examined. The isotherm data fit the Langmuir isotherm model, indicating chemical adsorption and likely irreversibility of the process, according to the results. At 298, 308, and 318 K, the adsorption capacities of Ni(II) were determined to be 10.267, 11.834, and 12.285 mg/g, respectively. Adsorption kinetic data revealed that the adsorption of Ni(II) metal ions followed the pseudosecond-order kinetic model. According to thermodynamic studies, Ni(II) ion adsorption on the MC is spontaneous and endothermic. MC has proven to be an effective and alternative material for the removal of Ni(II) ions from aqueous media due to its excellent removal ability, availability, and low cost, as well as its features such as being able to be used without any chemical treatment and being environmentally friendly.

Mercury is known to be one of the most toxic heavy metals in the environment and is released into the water systems in significant quantities through natural events and industrial process activities. Many chemical materials are used as adsorbents in the removal of toxic metals from the environment and wastewaters. However, using microorganisms as bio-sorbents instead of chemical materials has become common recently due to their low cost, easy availability and presence in nature. In this study, Bacillus licheniformis in the soil isolated from the Tigris River was used as bio-sorbent. The mercury (Hg(II)) absorption behaviour of Bacillus licheniformis bacteria (BLB) was investigated using inductively coupled plasma mass spectrometry. The effects of equilibrium of adsorption time, temperature, adsorbent dosage and pH on the adsorption of Hg (II) onto BLB were determined. The maximum adsorption capacity of Hg (II) onto BLB was determined as 82.12 mg/g (T = 25 degrees C, pH 5, Co = 50 mg/L, m = 25 mg). The BLB was characterised using Fourier transform infrared spectroscopy analysis, thermal gravimetric analysis/differential thermal analysis, scanning electron microscopy analysis and energy-dispersive X-ray spectroscopy analysis. In addition, pseudo-first-order and pseudo-second-order kinetic models were applied. The equilibrium data for the adsorption of Hg(II) onto BLB were examined by the Langmuir and Freundlich isotherm models. The activation energy was calculated using the pseudo-second-order rate constant. These results suggested the BLB can be used as an efficient adsorbent for the removal of Hg(II) metal ions from wastewater. When the results of bio-sorption studies were examined, it was found that the bio-sorbent could be reused easily. The present study suggests that microorganism bio-sorbents are useful for the efficient removal of mercury from aqueous solutions.

This study was performed to determine the presence and levels of aflatoxin M-1 (AFM(1)) in yoghurt produced by traditional methods in small scale enterprises in Mardin and Sanliurfa provinces located in Southeastern Turkey and to evaluate the yoghurt in terms of food safety. A total of 90 yoghurt samples, 42 from Mardin and 48 from $anhurfa were collected from small-scale retailers and tested for AFM(1) by enzyme-linked immunosorbent assay (ELISA). AFM(1) was detected in 34 (37.8 %) of 90 yoghurt samples at the levels ranging from 10 to 515 ng/kg. Five (11.9 %) samples (ranging from 10 to 515 ng/kg) from Mardin and 29 (60.4 %) samples (ranging from 10 to 101 ng/kg) from Sanliurfa were found to be contaminated with AFM(1). There was a statistically significant difference between the samples collected Mardin and Sanliurfa concerning the presence frequency of AFM(1) (p=0.000). The AFM(1) levels of 16 (17.8 %) positive yoghurt samples were higher than the legal limits. The results of this study have revealed that the traditionally produced homemade yoghurt is contaminated with AFM(1) and poses health risk for consumers.

(Springer Verlag, 2017) Kılıç Altun, S.; Gürbüz, S.; Ayağ, E.
This study was performed to determine aflatoxin M1 (AFM1) in human breast milk samples collected in Şanlıurfa, located in Southeastern region of Turkey, and to investigate a possible correlation between AFM1 occurrence (frequency and levels) and sampling seasons. Human breast milk samples collected in December 2014 and in June 2015 from a total of 74 nursing women, both outpatient and inpatient volunteers in hospitals located in Şanlıurfa, Turkey, were analyzed using competitive enzyme-linked immunosorbent assay (ELISA) for the presence of AFM1. AFM1 was detected in 66 (89.2%) out of 74 samples at an average concentration of 19.0 ± 13.0 ng/l (min.-max., 9.6–80 ng/l). There was a statistically significant difference between December and June concerning AFM1 levels (p < 0.05). Further detailed studies will be needed to determine the main sources of aflatoxins in food, to establish protection strategies against maternal and infant exposure to these mycotoxins. © 2016, Society for Mycotoxin Research and Springer-Verlag Berlin Heidelberg.
