Yamadağ Volcanics which is one of the examples of the Late Miocene volcanism in Eastern Anatolia covers largeareas within the boundaries of Arguvan county of Malatya. The gemstones, subject of this research range from afew centimeters to about 30-40 cm in size and are formed in the cavities of the basalts beonging to Yamadağvolcanics. These gemstones seem to have formed as veins extending in east-west direction and consist of opal (opal-CT) and chrysocolla. Opal formations have various colours such as white, brown, yellow and greenish, while chrysocolla formations are bluish-greenish in color. both opal and chrysocolla are of massive type and their freshsurfaces display waxy luster. Mineral paragenesis and formation conditions of gemstones and are determined byapplying XRD, SEM, FT-IR techniques. ICP-MS technique is used for the determination of the geochemicalcompositions. The gemological characteristics are identified via cabochon and facet cut techniques by usingdiamond coating blade, sintered diamond abrasive discs and polishing machine. Opals are usually composed oftridymite minerals, also in some cases quartz and cristobalite minerals accompany the tridymite minerals. The EDXmeasurements reveal, enrichment of Fe and Al in opals, and of Cu in chrysocolla. The ICP-MS measurements, in chrysocollas reveal, enrichments in LIL elements such as Ba, Sr and in HFS elements such as U. Consequently,gemological studies show that the chrysocolla and opals in study area, which have waxy luster and massivestructure, are suitable for utilization as a gemstone due to its color, hardness, durability, homogeneous distributionof color and processability

Bu çalışmada yetiştirme sistemleri ve tavuk yaşının, tavukların serum ve yumurtalık dokusundaki bazı oksidatif stres parametreleri üzerine etkileri incelendi. Bu amaçla 30 ve 60 haftalık yaşta, iki farklı sistemden (konvansiyonel kafes ve organik) toplam 48 adet ticari yumurtacı hibrit olan Bovans White kullanıldı. Kesim işlemini takiben tavukların serum ve yumurtalık dokuları toplanarak, malondialdehid (MDA), glutatyon (GSH), glutatyon peroksidaz (GSH-Px) ve katalaz (CAT) düzeyleri belirlendi. Konvansiyonel kafeste yetiştirilen hem 30, hem de 60 haftalık tavukların serum MDA düzeyleri önemli derecede yüksek bulundu (P<0.05). Konvansiyonel kafeste GSH-Px aktivitesi düşük, aksine CAT aktivitesi önemli düzeyde yüksek tespit edildi (P<0.05). Tavuk yaşı serum MDA, GSH, GSH-Px ve CAT düzeylerini etkilemedi (P>0.05). Buna ek olarak, serumda, yetiştirme sistemi ve tavuk yaşı arasında önemli bir etkileşim bulunmadı (P>0.05). Konvansiyonel sistemdeki tavukların yumurtalık dokusunda MDA (P=0.010) ve GSH (P<0.01) seviyeleri önemli düzeyde yüksek bulunurken, GSH seviyesi 60 haftalık yaşta arttı (P<0.01). GSH-Px ve CAT aktiviteleri gruplar arasında benzer çıktı (P>0.05). Yetiştirme sistemi ve tavuk yaşı arasındaki etkileşim yumurtalık dokusunda CAT aktivitesini etkiledi (P<0.05). Sonuç olarak, konvansiyonel bataryalı kafesler, lipid peroksidasyon ve MDA düzeylerinin artmasıyla ilişkili olarak tavuklarda oksidatif strese neden oldu. Bu sistemde MDA'nın azalmasında rol oynayan antioksidan enzimler yetersiz kaldı. Oksidan/antioksidan dengesi 30 ve 60 haftalık yaşlarda tavuk organizması tarafından kurulabildi ve dolayısıyla dokuların MDA düzeyleri yaştan etkilenmedi

Dogan, Onur; Ayçin, Ejder; Bulut, Zeki Atil
Companies need to understand the customers' data better in all aspects. Detecting similarities and differences among customers, predicting their behaviors, proposing better options and opportunities to customers became very important for customer-company engagement. Segmenting the customers according to their data became vital in this context. RFM (recency, frequency and monetary) values have been used for many years to identify which customers valuable for the company, which customers need promotional activities, etc. Data-mining tools and techniques widely have been used by organizations and individuals to analysis their stored data. Clustering, which one of the tasks of data mining has been used to group people, objects, etc. In this paper we propose two different clustering models to segment 700032 customers by considering their RFM values. We detected that the current customer segmentation which built by just considering customers' expense is not sufficient. Hence, models that recommended in this research are expected to provide better customer understanding, well-designed strategies, and more efficient decisions.

The aim in this study is speciation and determination of arsenic in chicken meat matrix. For this purpose, chicken meat samples consumed commonly by Turkish people belonging to five different companies in Turkey were obtained from markets once per 15 days during 14 months. The samples were digested in microwave oven by using both nitric and hydrochloric acid. It was found that microwave digestion method can be used successfully in the speciation analysis of arsenic. The determination and speciation of As in solutions were carried out by hydride generation-atomic absorption spectrophotometry (HG-AAS). From the observed results, concentrations of As (V) were ranged between 3.0-14.0 ng g(-1) (mean 7.3 ng g(-1)) for breast tissues and 3.0-9.0 ng g(-1) (mean 5.1 ng g(-1)) for leg tissues. The concentrations of As (III) in all studied chicken tissues were found lower than the limit of detection (2 ng g(-1)).

Ozcan, Ebru Ifakat; Serdar, Osman
In this study, a new method (Artificial Neural Networks) to estimating some population parameters of Tigris loach (Oxynoemacheilus tigris (Heckel, 1843)) collected between 2014 and 2015 in 14 different stations from Karasu River (East Anatolia, Turkey). The total length and weight of the species ranged from 62 to105 mm and from 1.7 to 10.9 g for females and 65 to 100 mm and from 2.4 to 9.8 g for males, respectively. The new maximum length for O. tigris was found to be 105 mm in this study. The length-weight relation of O. tigris was carried out with artificial neural networks (ANNs) and length-weight relationships (LWRs). The results obtained were compared. Length-weight relationships of O. tigris were found as W=0.0049*L-3.29 , R-2 =0.95 for all individuals. According to these values, the growth type of this species was positive allometric (b>3) for all individuals. Regression analysis showed that fish length has high significant correlation with weight (R=0.97, R-2 =0.95, F-1,F-185=31930.3, P<0.001). According to the comparison of the results obtained with MAPE (%), ANNs provide better results than the LWRs. The results of this study could give useful insight that ANNs can be evaluated as an alternative for length-weight relation estimation. The condition factor values (min-max) were observed as 0.680-1.239 for females and 0.699-1.074 for males. No studies have been done before on this species population parameters.

OBOR attempt has manifested the force of Chinese geopolitics and geoeconomics. OBOR is a project where China places in its center and also involves Asia, Europe, Middle East and partly the Africa. Transportation networks, telecommunication, energy networks with the international integration are aimed at this project. OBOR attempt has pretty large territorial limits. It covers 69 member countries, 65% of the world population, 42% of the world's GDP, 75% of the energy reserves known, 40% of the square measure of lands of the world. China has planned the attempt to bring into force in 2049 when will be the 100th year of the foundation of PRC by completing the infrastructure investments within 30-35 years. Much as completing the project has extended over a period, China targets to reach $ 2,5 trillion of annual trade volume among OBOR countries within ten years. OBOR must not be seen as just composed of the infrastructure projects. It is observed that the attempt is going to turn into an international integration by the adaptation in commercial law, establishing free trade areas, and the customs treatises. This paper aims to analyze OBOR attempt that is the subject of the geographical location of the developing processes.

Yogurtcu, Hakan
In this study, the rheological behaviour of semisolid peanut butter samples with a fat ratio of 42.7 % were examined in a temperature interval of 10-50 degrees C via rotational rheometer at different shear rates. Peanut butter samples display non-Newtonian yield-pseudoplastic behaviour. Seven model equalities were used for representing the time-independent rheological behaviour of peanut butter and the representation ability of the models were determined by way of determination coefficient (r(2)), mean absolute percentage error (MA%E), chi-square (chi(2)) and root mean square error (RMSE) statistical parameters. It was observed that the O'foli model was the most successful among the models applied to experimental data. Temperature dependency of viscosity at shear rates of 0.1, 0.4 and 0.75 s(-1) was determined via Arrhenius equality and activation energies varied between the interval of 46818.63-51952.52 J/mol. Three-layer model suggested for estimating viscosity using artificial neural network method was observed to be quite successful.

Yilmaz, E.; Ates, M.; Sahilli, Y. C.
Researches on nano-structured materials (<100 nm) are increasing rapidly in the direction of technological developments. Synthesis and modification of quantum dots, known as nanomaterials and nanocrystals, have become an important aspect of nanotechnology. The reason for this is that it has many potential applications in the field, including biomedicine and pharmacology. The unique properties and biological effects of nanostructured particles indicate that they can potentially be used as an alternative in the treatment of various diseases. In this work, PbSe quantum dots were synthesized by chemical method and modified by chitosan coating. The characterization of PbSe was done by TEM, SEM, XRD, DLS and Zeta potential analysis methods. When the morphological structures of the quantum dots obtained by chemical synthesis were examined, round and spherical nano-sized particles (<20 nm) of all PbSe were obtained according to TEM and SEM results. It has been seen that PbSe quantum dots have a positive (+) surface charge and are highly stable (40 + mV). In addition, the increase in oxidation resistance of PbSe coated with chitosan was found in XRD results. As a result of this research, small size and biopolymer coated and thus more stable quantum dots could be obtained. It has also been found that PbSe quantum dots coated with biopolymers like chitosan may have the potential to be used in pharmacology and biomedical applications.

Koroglu, Kemalettin; Danismaz, Harun
Stepped rock-cut tunnels are among the most interesting remains at many fortresses in Eastern Anatolia. The construction of these tunnels, which are cut deep into rock surfaces up to a length of 350 m, must have been at least as difficult as that of the fortification walls and expertise would have been required. Stepped rock-cut tunnels and associated fortresses in Eastern Anatolia have not so far been evaluated as a whole. The stepped rock tunnels in Eastern Anatolia have been accepted as one of the basic criteria indicating the Urartian period since the beginning of the 20th century. In this study, we first consider the types of stepped rock-cut tunnels in Eastern Anatolia, the purposes of their construction, and their distribution. We then discuss their dating and our interpretation of the period of their arrival in the region of Eastern Anatolia.

Yazici, Muge; Zabci, Cengiz; Sançar, Taylan; Natalin, Boris A.
Although the westward extrusion of the Anatolian Block is mainly compensated along its boundary faults, the North Anatolian and the East Anatolian shear zones, it is internally deformed in a dominant manner by some strike-slip faults as well. To obtain a better understanding about this intraplate deformation of the Anatolian Block, we investigate the tectonic geomorphology of the Ovaak Fault (OF), which is the northeastern member of the Malatya-Ovaak Fault Zone (MOFZ). Further, we apply the most common geomorphic indices, such as the hypsometric curve and integral, longitudinal channel profiles, channel steepness and concavity, mountain front sinuosity, and valley height-width ratio to characterise and quantify the deformation along the OF and the surrounding region where the regional morphology is shaped with the joint effect of palaeo- and neotectonics and other morphological factors such as palaeoglacial processes. The highest hypsometric integral, steepness and concavity values are generally observed along the northeastern strand of the OF (the Munzur Mountains) and the Kemaliye Region. Further, we interpret that high HI and steepness values indicate a regional tectonic uplift because of either a change in fault geometry, which gives rise to the vertical component on the OF, or a regional high convergence zone. Furthermore, this study gives the first calculation of vertical uplift in the northern margin of the Ovacik Basin (OB) as at least 0.5 mm/y for long term deformation history. Thus, our results exhibit that the OF is one of the intraplate strike-slip faults of the Anatolian Block. (C) 2018 Elsevier B.V. All rights reserved.

Esen, Yuksel; Dogan, Zulfu Murat
Limonite (Fe2O3.xH(2)O) is a soft or brown, hard iron mineral, usually in yellow colour. It is also used as a pigment since it contains iron ore. It is believed that it can also be used in the production of heavy concrete due to its 60% iron ore content. In this paper, an experimental study was carried out on radiation shielding properties and certain physical and mechanical properties of normal and limonite reinforced concrete. For this purpose, with the normal concretes prepared according to standards, amounts of aggregates were reduced at the rates of 20%, 40%, 60%, 80% and 100% by volume respectively, and heavy concrete mixes were prepared that were obtained by adding limonite at the same rates in their place. With limonite reinforcement, compressive and flexural strength of the concrete produced decreased, water absorption amount increased and their radiation permeability significantly decreased.

The species of the genus Hirudo are threatened but still used worldwide in human treatment. We studied the density changes of southern medicinal leech Hirudo verbana and some water quality parameters monthly during a year in the Akpinar Marsh, Eastern Anatolia, Turkey. Samples of H. verbana were collected using a modified unit square design and unit time collecting method as an indicator for population density. Some water parameters such as water temperature, dissolved oxygen, pH, some cationic elements (lithium, sodium, ammonium, potassium, magnesium, calcium) and anionic elements (fluoride, chloride, sulphate, nitrate, phosphate, bromide) were determined. These parameters were analysed to detect their impact on population density of this medicinal leech. The populations of H. verbena were most dense in May-June; the species was found in smallest numbers in November and hibernating in December-March. A significant correlation (p<0.05) between the number of medicinal leeches in the unit area and monthly water temperature, amount of ammonium and fluoride was determined using the Pearson correlation coefficient. In the Akpinar Marsh, the largest adult medicinal leeches (>5 g) in the fourth size group formed 12.50-27.50% of the population and the smallest (<1.0 g) in the first size group formed 7.50-38.24%.
