    Diauehi and Urartian Tribal Centers in the Context of the Urartian Administration System; [Urartu Kralligi'nin Idari Sistemi Baglaminda Diauehi ve Urartu Aşiret Merkezleri]

    Danişmaz, Harun; Konyar, Erkan

    The Diauehi region, located in the northwest border of Urartian Kingdom, is called the Upper Aras basin nowadays. The Urartian remains in the Upper Aras basin have been found in the Hasankale/Pasinler, Marifet and Yoǧunhasan fortresses. Apart from these settlements, to the east of the basin are the Hamamli and Hasankale inscriptions, to the south are the Avnik, Delibaba and Yazilitaş inscriptions, and the Süngütaş inscription is located on the route to the north. From its early years onwards, the Urartian Kingdom tried to transform the Diauehi region through military campaigns and administrative arrangements. However, this transformation appears to have been different from the center of the kingdom, the Lake Van Basin, where the majority of the royal cities we are located. Instead of building new cities in the region, the kingdom's strategy was focused on conducting military campaigns to weaken the existing tribes and allying with the powerful ones. During the military campaigns dating to the early years of the kingdom, the tribe leaders who were also named as kings paid a tribute and accepted the authority of Urartians.

    The Effect of Resveratrol on The Oxidative Stress in Rats Treated with Irradiation

    Ozcelik, Mehtap; Erisir, Mine; Guler, Osman; Baykara, Murat; Bulmus, Funda Gulcu

    The antioxidant and protective effect of resveratrol against irradiation induced oxidative damage were researched. Twenty-one rats were seperated into 3 groups; First group was the control group. Second group was the irradiation group; received physiological saline intraperitoneally (i.p.) for three days, then 9 Gray (Gy) irradiation was applied. Third group was irradiation+Resveratrol group; received 10 mg/kg resveratrol i.p. for three days and then the same dose of radiation was applied. As a result of irradiation, a significant increase was found in the level of malondialdehyde (MDA) in the liver, kidney and brain tissues of rats (P<0.001). Glutathione peroxidase (GSH-Px) activity in all the tissues and superoxide dismutase (SOD) activity, Glutathione (GSH) levels in liver decreased (P<0.01), GSH levels in kidney, spleen and ovarium tissues significantly increased (P<0.05). The giving of resveratrol significantly reduced the MDA levels increasing in liver, kidney, and brain as a result of irradiation (P<0.001) and the liver MDA levels reached to the control levels. By giving resveratrol, it was determined that all the antioxidants studied reduced significantly compared to the control group and/or the irradiation group (P<0.05). According to the data obtained as a result; It was concluded that resveratrol shows a corrective effect by changing the oxidant/antioxidant balance against oxidative stress caused by irradiation, therefore resveratrol is a powerful antioxidant.

    3d surface modeling of late pleistocene glaciers in the Munzur mountains (Eastern Turkey) and its paleoclimatic implications

    Çilğin, Zeynel

    Located in the Eastern Anatolian Region in Turkey, the Munzur Mountains (Munzurs; 3463 m above sea level) are one of the most important glacial landscapes in Turkey, with evidence for extensive glaciations in the past and small-scale glaciation at present. As Turkey’s second-largest glaciated region, these mountains include various glacial landforms, primarily glacial valleys, hanging valleys, cirques, and moraines. However, only limited data are available on the extent and chronology of former glaciations in the Munzur Mountains. This study produced data on the extent of paleoglaciers, calculated their equilibrium line altitudes (ELAs), revealed paleoclimate conditions, and modeled paleo temperatures during maximum ice extent using numerically derived reconstruction methods (GlaRe and ELA calculation tools) based on geomorphic evidence. The major glacial landforms were first mapped in detail before the reconstruction. Six hundred and eighty cirques and 30 glaciated valleys were identified. Paleoglaciers did not override the entire mountains, however, valley glaciers converged where topographic conditions were suitable.The maximum extent of glaciation covered an area of ca. 600 km2. The largest glacier was ca. 19 km in length. Moreover, 15 of the valley glaciers were over 10 km in length. Their average thickness was 75 m, and the maximum glacial thickness, in the Eastern Munzurs, was found to be ca. 300 m. The total volume of ice reached ca. 45 km3. The paleoglaciers reached as low as 1350 m above sea level. The average ELA was calculated approximately 2600 m above sea level, indicating an equilibrium line altitude depression of 1000–1100 m. The paleotemperatures, estimated based on different scenarios at the time of the maximum extent of Munzur glaciers, were 8–10 °C lower than today. The mountains experienced an increase in precipitation through this period with respect to the current precipitation scheme.

    Effect of surfactant types on particle size and morphology of flame-retardant zinc borate powder

    Ipek, Yeliz

    Zinc borate is a boron-containing chemical material that is used to increase the flame retardancy of polymeric materials, dyes, cables, fabrics, carpets, and the internal parts of automobiles and planes. Commercially used zinc borate, which has the formula of 2ZnO·3B2O3·7H2O, has a particle size between 10 and 20 μm. However, recent studies have shown that nanosized flame retardants have more superior flame retardancy and less negative effects on mechanical properties than microsized flame retardants. Nanosized flame retardants disperse more homogeneously and even low quantities are sufficient to provide high flame resistance. In this study, nano zinc borate powder was synthesized by a wet chemical method and the effects of nonionic, anionic, and cationic surfactants on the particle size and morphology of the zinc borate particles were investigated. Chemical purity and physical structures of the synthesized zinc borate powder were analyzed by XRD, FTIR, TG-DTA, TEM, and Zetasizer. The analysis results showed that the zinc borate powder had a chemical formula of 2ZnO·3B2O3·7H2O. TEM and Zetasizer results indicated that the nano zinc borate powder, which had nanoscale particle size distribution with needle- and flake-like structures, was synthesized using nonionic, anionic, and cationic surfactants.

    This study aims to identify wild plants used for medical purposes by local people of the Ballakayati district of Erbil in North Iraq, and to determine the local names and uses of those plants. The study was carried out for approximately 3 years between 2016 and 2018. During this period of time, 85 plant specimens were collected. Demographic characteristics of the participants, names of the local plants, used parts of these plants and their preparation methods were investigated and recorded. In the literature analysis of the plants used in this study, 85 plants were found to be used for medicinal purposes while 3 plants were not found in the literature records. Local plant names differ due to local dialects in North Iraq. Locals benefit from the wild plants growing in their districts. In this area, it was found that locals use 85 plants from 38 families for curative purposes. The medicinal plants were used for the treatment of many diseases, mostly for the treatment of a cold, shortness of breath, and heart and gastrointestinal diseases. It was determined that the plants we identified in this study were used directly or as infusion or decoction. The most considerable medicinal plants were Mentha longifolia (L.) L. subsp. noeana (Briq.) Briq. (UV:0.38), Urtica dioica L. (UV:0.38). Furthermore, plants used for medicinal purposes are dried and stored for using them in winter. The medicinal use of Rhaponticum repens (L.) Hidalgo and Tanacetum polycephalum Sch.Bip. subsp. argyrophyllum (K.Koch) Podlech. that we found in this area were recorded for the first time. Different use of those plants were observed in this study.

    Codas ve entropi yöntemleri ile yenilenebilir enerji kaynaklarının düzey 1 bölgelerine göre incelenmesi

    Arsu, Talip; Aycin, Ejder

    Dünya’daki enerji üretimi ağırlıklı olarak fosil kaynaklı yakıtlar kullanılarak gerçekleştirilmektedir. Fakat fosil kaynaklı yakıtlar doğada sınırsız olarak bulunmamasının yanı sıra ekolojik doğal dengeyi de olumsuz yönde etkilemektedir. Yenilenebilir Enerji Kaynakları (YEK) ise fosil yakıtlardan elde edilen enerjiye göre hem ekolojik hem de ekonomik anlamda büyük kazanımlar sağlamaktadır. Bu kazanımların farkına varan ülkeler enerji politikalarında YEK’lere daha fazla önem vermektedir. Türkiye gibi YEK’lere elverişli kaynaklara sahip ve gelişmekte olan ülkeler yenilenebilir enerjinin geleceğinde söz sahibi olmaya adaydırlar. Bu açıdan Türkiye gibi ülkelerin YEK performanslarına göre değerlendirmek gelecek için yararlı bilgiler sağlayacaktır. Fakat bu değerlendirmeyi yaparken Türkiye’yi bir bütün olarak ele almak yerine birbirinden farklı YEK potansiyellerine sahip bölgeler olarak ele almak daha yerinde olacaktır. Bu noktadan hareketle çalışmanın amacı Türkiye’deki Düzey 1 bölgelerinin YEK performanslarına göre değerlendirilmesi olarak belirlenmiştir. Bu amaçla Düzey 1 bölgeleri Entropi ve CODAS yöntemleri bütünleşik olarak kullanılarak incelenmiştir. Entropi yöntemi ile elde edilen sonuçlara göre en önemli kriterler sırasıyla, güneş enerjisi kurulu gücü/toplam kurulu güç, rüzgar enerjisi kurulu güç ve güneş enerjisi kurulu güç kriterleri olarak belirlenmiştir. CODAS yöntemi sonuçlarına göre, sırasıyla TR5- Batı Anadolu, TR3- Ege ve TR7-Orta Anadolu bölgeleri ilk üç sırada yer alırken, TRA- Kuzeydoğu Anadolu, TR1- İstanbul ve TR4- Doğu Marmara bölgeleri son üç sırada yer almıştır.
