The objective of this study was to investigate the presence of anti-Brucella antibody and Brucella spp. DNA in cow, sheep and goat milk and in Urfa cheese collected from markets and bazaars in Sanliurfa, located in southeast of Turkey. A total of 258 samples consisting of 178 raw milk (48 cow milk, 65 sheep milk and 65 goat milk) samples and 80 Urfa cheese samples were investigated. Anti-Brucella antibody was detected by indirect ELISA (i-ELISA), and the presence of Brucella spp. DNA was screened by real time Polymerase Chain Reaction (RT-PCR). 16.6% of the cow, 6.1% of the goat and 6.1% of the sheep milk and 16.25% of the cheese samples were found as positive for brucella antibodies by i-ELISA. The RT-PCR assay amplified Brucella DNA from 18.75, 7.6 and 6.1% cow, goat and sheep milk samples respectively. Brucella DNA was amplified from 22.5% cheese samples. The 11.2% and 13.9% of the samples were found as positive by i-ELISA and RT-PCR respectively. This study indicates that milk and milk products consumed in Sanliurfa poses a risk to public health in terms of brucellosis. The combining usage of both i-ELISA and RT-PCR methods could lead to more reliable results to detect anti-Brucella antibody and Brucella spp. DNA from milk and cheese samples. © 2016 PVJ.

Rhizobacterial application is efficient approach and process focusing less chemical fertilizers for increasing soil fertility and nutritional value of grains for different crops. This study investigated the effect of Pseudomonas fluorescens rhizobacterial application on the yield, yield components, grain quality and content of nutrition elements in wheat and in soil. Experiments were designed according to randomized complete block design with four replications in environmental conditions of Diyarbakir province, Turkey, during 2014 and 2015 growing seasons. Four treatments of Pseudomonas fluorescens rhizobacteria (control, seed inoculation, foliar application, seed + foliar) were used to investigate their effects on various aspects of wheat crop. Results of present study indicated that P. fluorescens rhizobacteria applications significantly (P=0.05) affected grain yield, Al, K, Mg, and Zn content in grain, total N, and available P, K, Fe, and Mn elements in soil. The maximum grain yield was obtained from the combined application of seed inoculation + foliar application and showed 7% higher yield than in the control. Study indicated that application of rhizobacteria has positive effect on soil productivity, yield and nutritional quality of grains.
Ganoderma Lucidum Alleviates Ischemia-Reperfusion–induced Renal Injury in Wistar Rats
(Science Printers and Publishers Inc., 2021) Dönder, A.; Aşır, F.
OBJECTIVE: To investigate effects of Ganoderma lucidum (G. lucidum) kidney sections of rats induced by ischemiareperfusion (I/R) injury. STUDY DESIGN: A total of 40 rats were assigned to 4 groups: control (Sham), I/R, G. lucidum, and I/R+G. lucidum groups. Prior to animal experiments, 20 mL/kg G. lucidum was administered to the G. lucidum–treated groups for 7 days. The control and I/R groups received only saline solution. The kidney was exposed to hypoxia for 1 hour by clamping renal vessels and was then allowed to reoxygenate for 6 hours. Blood was taken to measure for serum MDA, MPO, and GSH. Kidney tissues were resected for histological paraffin tissue protocol. Hematoxylineosin and immunohistochemical staining were performed. RESULTS: MDA and MPO levels were highest in the I/R group but were close to the levels of the control group in the I/R+G. lucidum group. Unlike MDA and MPO values, GSH values were the lowest in the I/R group, but after G. lucidum treatment, GSH levels increased in the I/R+G. lucidum group. In kidney sections of hematoxylineosin staining, the control group showed no pathology. In the I/R group, atrophic glomeruli, degenerated tubular cells, and mononuclear cell infiltration with dilated and congested vessels were observed. In the I/R+G. lucidum group, I/R pathology was mostly recovered. In the G. lucidum group, ADAMTS4 expression was moderately expressed in glomerular and tubular cells. The I/R group showed positive ADAMTS4 expression in mostly inflammatory cells. In the I/R+G. lucidum group, ADAMTS4 was positively expressed only in glomerular structures. In the G. lucidum group, caspase3 expression was observed in glomerular and tubular cells. The I/R group showed strong caspase3 activity in glomerular and tubular cells, in vascular cells, and inflammatory cells. The I/R+G. lucidum group showed weak caspase3 expression. CONCLUSION: Ischemiareperfusion injury caused histopathological and biochemical alterations in renal tissue; G. lucidum protected tissue structure and integrity by its antioxidant and antiinflammatory properties. © Science Printers and Publishers, Inc.

(Milli Folklor Dergisi, 2014) Uygur, H.K.; Uygur, Hatice Kübra; 02.15. Department of Turkish language and Literature / Türk Dili ve Edebiyatı Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Transmission of tradition provides bondage between generations in multi cultural societies by means of the transmission of cultural codes between generations. Cultural heritage of Mardin which bonds people from different lingual and religious backgrounds can be traced back in entertainment practices. These practices convey past to present with its traditional character. The traditional entertainment ritual in Mardin is called "Leyli Nights". They provide the basic elements of Mardin's culture and entertainment practices. Leyli Nights are also significant for being a part of transition rituals such as bridal and circumcision ceremonies. Nevertheless as these ceremonies take place in different locations due to the change in life styles; Leyli nights' character also changed especially in places where it became a tourist attraction. This shift in its context and authenticity will be discussed. Our study is a folkloric one which takes music in Leyli Nights as means of communication. In addition, the multi lingual and multi religious structure of the region is reflected in these entertainments. Rituals and practices of Leyli Night entertainments, (both traditional and touristic) which is an important phenomenon in Mardin's entertainment culture, and introduction of collective singing practices are subject of this study.

(Hacettepe Unıv, 2012) Yildirim, M.C.; Demirtaş, H.
The purpose of study is to evaluate the teacher supervision practices in terms of constructivist learning paradigm principles in the primary schools based on the opinions of the supervisors and the teachers. Both quantitative and qualitative research methods were used in the study. As quantitative method, the scale which was developed by the researcher and as qualitative method the focus group interview and document analysis techniques were used. Parametric and nonparametric analysis techniques were used in the analysis of quantitative data. The sample of the study is consisted of 367 teachers and 42 primary education supervisors so as to collect quantitative data and 12 teachers and 12 primary education supervisors for qualitative data, all of which work in Şanliurfa city central district. Content analysis was applied to the qualitative data. According to supervisors' opinions, the primary education supervisors usually observe five dimensions of teacher supervision in terms of constructivist learning paradigm principles on the supervision of teachers. On the other hand according to teachers' opinions, the primary education supervisors usually observe these dimensions; the activities related to the teacher's administrative tasks, the activities of planning the instruction and organizing the learning environment, the activities of encouraging the learning. However, they sometimes observe these dimensions; the activities of skill development and evaluation, the activities of improving the thinking. The results show that there are some problems in supervision processes, supervisory duties and supervision laws and regulations in teacher supervision.

Assessment of Correlative Digital Drawing Features in the Design Processes of Unstructured Creativity
(Ecaade-education & Research Computer Aided Architectural design Europe, 2023) Aydin, Serdar; Aydın, Serdar; Sik, Busra; Yoruk, Merve Sule; Aktas, Begum; 08.02. Department of Architecture / Mimarlık Bölümü; 08. Faculty of Engineering and Architecture / Mühendislik Mimarlık Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
This research critically challenges the conventional perception of drawings as mere technical blueprints and delves into the intricate integration of design ideation, abstraction, and speculation with geometrical manipulations and semantic labelling. By focusing on unconventional architectural design studio experiments at the undergraduate level, the study aims to explore the role of creativity in speculative drawing. It adopts a 3-dimensional design thinking process that transcends the rigid constraints of traditional drawings and embraces the fluidity of representational norms. Furthermore, the paper elucidates on the pedagogical aspects of the design studio, including the unstructured creativity inherent in the design process. The methodology employed in this study is exemplified through different stages of the design studio, incorporating a variety of representations such as 2D, 2.5D, and 3D, encompassing scalar, geometric, and material transfigurations. To assess the outcomes of the studio, the research utilises correlation diagrams that establish connections between digital drawing features at different stages and the unstructured creativity manifested in the final design. These scatter and correlation diagrams capture the syntactic relationships between the objects within digital drawings. The findings of this study reveal insight on the nuanced interplay between intuitive, reflective, and retrospective aspects of unstructured creativity during the design ideation process. By unravelling the intricate role of digital design tools and methods this research contributes to a deeper understanding of how design ideation is generated and manifested through the dynamic interplay of the modulating compounds of drawing objects. It highlights the significance of meaningful, conceptual, and speculative representations that directly relate to the creation of buildable forms and architectural spaces. Through its critical insights, this study paves the way for advancements in the field of CAAD and offers valuable perspective for architectural education and practice.
The Preservation Problems of Masonry Houses in Baspinar Rural Settlement
(Crc Press-balkema, 2016) Yildiz, H.
Baspinar Village is a rural settlement in Kemaliye town of Erzincan province located in the East Anatolian Region of Turkey. The history of the village dates back to the 18th century. The traditional fabric of the houses comprises of stone masonry terraced constructions with three to four floors. Baspinar sits on a sloping geography; hence the buildings of the settlement are designed to harmonize with the regional topography. The masonry houses in Baspinar are quite different in terms of plan typology, facade design and construction techniques from those of Kemaliye town, located 38 km away from the village. The findings of the study are based on the evaluation of data collected from a field work of 25 days in July 2012. The fabric of the houses was physically analysed in terms of number of floors, building's use, building period, construction system and materials, authenticity and preservation state. 216 building inventory cards have been prepared to identify structural problems through external observation. The purpose of this investigation is to examine the main problems of Baspinar's masonry architectural fabric which are user's faults, unqualified restorations and deserted buildings. Moreover, some houses were divided into two or three independent houses because of ownership problems. Baspinar houses, which are not registered in national cultural heritage inventory list except the Baspinar Mosque, feature outstanding cultural landscape characteristics. First of all, the authentic masonry fabric of the settlement should be entirely preserved in a legal sense to solve the conservation problems. Furthermore, as part of sustainable conservation efforts, residents of the houses should avoid any interventions that may destroy the architectural authenticity of the houses, raising awareness on the use of available local materials and techniques.

The Church of Virgin at Amida and the Martyrium at Constantia: Two Monumental Centralised Churches in Late Antique Northern Mesopotamia
(Mersin University, 2013) Keser-Kayaalp, E.; Keser Kayaalp, Elif; 02.11. Department of History of Art / Sanat Tarihi Bölümü; 02. Faculty of Letters / Edebiyat Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Late Antique Northern Mesopotamia, which was situated at the eastern edge of the Byzantine Empire, was dotted with important cities such as Edessa (Urfa), Anastasiopolis (Dara), Amida (Diyarbakir), Martryropolis (Silvan), Constantia (Viranşehir) and Nisibis (Nusaybin). These cities were wealthy and highly cosmopolitan. As a result, the region had a sophisticated architecture which was by no means inferior to that found in other parts of the Byzantine Empire. This article deals with two monumental centralised churches in Northern Mesopotamia, namely the Church of the Virgin at Amida and the Octagon at Constantia. It concentrates firstly on the Church of the Virgin, which is an aisled-tetraconch church, a familiar plan type repeated in different parts of the Empire, and secondly on the Octagon at Constantia which has some unique features but shares the ambulatory design, long eastern chamber, use of materials and the monumentality with the aisled-tetraconch at Amida. By contextualising these two churches together, which has not been done in the past, this paper sheds further light on these neglected structures and reconsiders their reconstructions, dating, dedications and possible prototypes.

In this study, Health Transformation Program is discussed with reference to neo-classical health economics. The Ministry of Health (MoH), in order in order to control rapidly rising healthcare costs, has begun to shift to practices that increase the personal responsibility of patients, albeit partly. Additionally, MoH introduced performance-based pay when procuring services from public and private hospitals in order to improve productivity. Health professionals in Turkey point out that healthcare is a social right, and should not be restricted based on ability to pay. In fact, there is neither theoretical nor empirical support in neo-classical health economics literature that supports either personal responsibility of patients or performance- based pay to service providers.

Reliability Evaluation in Smart Grids Via Modified Monte Carlo Simulation Method
(IEEE, 2018) Wadi, Mohammed; Tür, Mehmet Rıda; Baysal, Mustafa; Shobole, Abdulfetah; Tur, Mehmet Rida; 17.02. Department of Electricity and Energy / Elektrik ve Enerji Bölümü; 17. Vocational Higher School / Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Operation of closed-ring power distribution systems has various advantages over both meshed-operated and radially-operated systems. Closed-ring system unlike to radial system, the voltage drop is less, achieves high reliability of power on demand since the power is supplied from both ends, and reduces the voltage fluctuation in high loaded areas by using a tie power line. However, the reliability assessment of closed-ring power grids is not a trivial task. Monte Carlo Simulation (MCS) is one of the most famous methods to assess the availability of any power system. However, the most proposed methods are able to evaluate the reliability of radial and open-ring grids. This paper developed the best known MCS method to assess the reliability of closed-ring grids by integrating the total loss of continuity (TLOC) definition into the MCS. The developed method is called modified Monte Carlo Simulation (MMCS) method. The MMCS is tested by using Roy Billinton Test System (RBTS) buses 2 and 4. The obtained results confirm the correctness of the proposed method. Therefore, MMCS method is appropriate to assess the reliability of both simple and complicated closed-ring systems.

Icp-Oes Multi-Element Analysis of Wheat Grown in Southeastern Turkey
(Perkin - Elmer Corp., 2017) Zahir Duz, M.; Duzgun, M.; Cam, B.; Serdar Çelik, K.; Kilinç, E.
The bread and durum wheat varieties grown in Southeastern Turkey are the main source of food consumed by the Turkish population and serve as bread and pasta. In this study, 12 kinds of durum wheat and 5 kinds of bread wheat samples registered by the International Agricultural Research and Training Centre of Turkey (IARTC, Turkey) were investigated for their multi-elemental concentrations (Ca, K, Mg, Fe, Zn, Mn, Si, Sn, Cu, Cr, Cd, Ni, V, Pb, As, and Se). The samples were microwavedigested and the elements determined by ICP-OES. The results were in good agreement with the certified values. This study shows that the elements Si, Fe, Zn, Cd, Cr, Cu, Sn, and Pb in durum wheat were higher than in bread wheat. Both wheat species were found to be rich in terms of Ca, Mg, and K. The multi-element content of some bread wheat and durum wheat was also in good agreement with the maximum allowable levels of the Food and Agriculture Organization (FAO) World Health (WHO).

Malnutrition is one of the major problems in the poor people of Bangladesh. There are some reports that additional nitrogen (over than recommended does) application to wheat plants result in more protein content in wheat grain. To justify these phenomena; the experiment was conducted in consecutive two years (2015-16 and 2016-17) at two locations (Gazipur and Dinajpur) during rabi season (November to March each year). There were used six nitrogen (N) treatments, such as 0, 100, 125, T-3; 150, 175 and 200 kg N hat. In the study, wheat cultivated at Dinajpur location exhibited more spikes m(-2), spike length, spikelets spike(-1), grains spike(-1), 1000-grain weight and higher grain yield in both years than Gazipur location. Considering combined N levels over the locations, the highest grain protein (14 %) as well as grain yield (5.00 t ha(-1)) was estimated when 200 kg N ha(-1) was applied. In economics point of view, 200 kg N ha(-1) application also gave the maximum (BCR, 1.21) followed by 175 kg N ha(-1) (1.20) and 150 kg N ha(-1) 1.20). Whereas, the maximum MBCR was found in 100 kg N ha(-1) (15.63). Therefore, to minimize malnutrition severity among the children as well as adult people in the developing countries like Bangladesh, 175 or 200 kg N ha(-1) may he applied in wheat to increase percentage protein in wheat grain.

This study was conducted to investigate yield and some agronomic traits of 10 regisreted barley cultivars (Hordeum vulgare L.) in Turkey in rainfall and supplemented irrigation conditions during 2011-12 and 2012-13 growing seasons at Diyarbakir/Çinar, Turkey. Experiments were arranged according to Completely Randomized Block Design with four replications. Obtained data was evaluated with variance analysis and GGE biplot method. Also, the barley cultivars were evaluated regarding to drought tolerance indices. According to mean of two years data grain yield of cultivars ranged from 417 to 578 kg/da in supplemented irrigation condition and from 281 to 391 kg/da in rainfall condition, while the mean of invastigated traits in supplemented irrigation and rainfal condition were 41 g and 38 g for 1000 kernel weight, 68 kg/hl and 62 kg/hl for test weight, 513 adet/m2 and 367 adet/m2 for number of spikes in sequmeter respectively. According to GGE biplot results G3 and G5 was determined as most stabil cultivars for grain yield. The highest grain yield was obtained in G3, G9, G5 and G10 for mean of the supplemented and rainfall conditions respectively (irrigation condition: 578; 533; 520; 550 kg/da, rainfall condition: 363; 365; 391 ve 363 kg/da). According to GGE biplot G9 is suitable for rainfall condition and G3 for irrigation condition. It was determined that YI (Yield index), was related to grain yield in rainfall condition, thus this parameter could be used in breeding programs to determine drought tolerance genotypes. The other drought tolerance indices such as HM (Harmonic Mean), GMP (Geometric Mean Productivity), STI (Stress tolerance index), MP (Mean productivity) and TOL (Tolerance) were related to grain yield in irrigation condition, so these parameters can be used to determine genotypes that suitable for irrigaton condition. © 2017 Namik Kemal University - Agricultural Faculty.

Stable and high yield varieties identification under various conditions prior to release as a variety is the main steps for breeding program. In order to exploit narrow and broad adaptability of genotypes and assess their effects, environment and GE interaction, 12 spring bread wheat genotypes were grown at four various experimental locations during 2013-14 and 2014-15 growing seasons. The stability and superiority of genotypes were identified by the AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x environment) biplot analysis. The AMMI analysis showed that the variance of genotype, environment and GE interaction were significant and the major treatment sum of squares were significantly affected by environments (85.47%), genotypes (8.51%) and GE interaction (6.07%). On the other hand, the first principal component axes (PCA 1) distributed to the complete interaction as 62.56%, and the second PCA 2 axes 37.44%. The GGE bi-plot analysis indicated that the total variation PC (principle component) was 83.09%, and PC1 was accounted as 63.69%, PC2 only 19.40%. The AMMI analysis showed that C11 was quite stable as well as the highest yielder among test genotypes, while C7 and C8 were unstable and low yielding across environments. The GGE biplot indicated that it was detected in two mega-environments, and the first mega-environment covered three environment (E1, E2 and E3), and the second mega-environment covered only E4. The genotypes C11 and C12 remained superior under ME I, while genotypes C1, C3 and C5 were for ME II. Among the genotypes, the genotype C1 may be recommended to be developed and released as an approved cultivar for being comparatively more stable and the highest yielder. Therefore the AMMI and GGE biplot models have an opportunity to determine the best genotypes under multiple environments considering on adaptability and stability concentrating on overall performance for screening superior genotypes.

Computer-assisted language learning (CALL) is one of the developing approaches that can assist to improve the language skills (reading, writing, listening) of students in English as a foreign language (EFL). CALL has been used to teach EFL learners through language drills or skills practice to stimulate discussion and interaction, or as a tool to improve writing and research. This study aims to point out the effects of DynEd on attitudes and language skills in EFL of middle school students in Turkey. The study contributes to the area of EFL learning and fosters students’ perceptions of EFL. The sample of this study, which utilized an ex-post facto design, recruited 136 middle school students as participants. According to the results, it can be said that, in addition to the conventional teaching environment, the use of DynEd significantly improved both the language skills and attitudes of the students in EFL. However, DynEd did not make any difference in students’ attitudes towards EFL according to grade level and gender. Moreover, students using DynEd have expressed positive views about DynEd. © 2021.
