Türedi, Salih; Topal, Mehmet Hanefi
This study analysis the relation between democracy and taxation in the context of developing countries. At the end of empirical analysis covering 60 countries by focusing on the period of 2006-2012, findings showing a two-way causality relation between taxation and democracy were reached. Accordingly, an increase in taxation level affects rule of law, organizational right, freedom of expression and belief positively in the countries analyzed. Briefly, it plays a vital role in the development of democracy by making a contribution to the enhancement of civil liberties. On the other hand, improvements in democratic rights and freedoms increase the number of citizens paying their taxes in full and on time, thus increases taxation level, by strengthening the harmony between citizens and state.

Sahin, Yasin; Ulutas, Guzin; Imamoglu, Mustafa Bilgehan
Protecting database integrity has become a matter of increasing importance nowadays as accessing information is getting easier. Therefore, database watermarking approach to protect the integrity become an active research area. Most of the existing relational database watermarking techniques embed a generated watermark in the database. Zero watermarking is employed in the proposed technique by storing the watermark generated from the database in another medium independent from the database. In order to make the method robust to column replacement attacks, cell values are split into overlapping pairs and column number is added to pairs. The histogram of pairs is used as the watermark because any change in either a cell value or column replacement would affect the histogram. Experimental results indicate robustness to column replacement attack as well as improved processing time compared to other works reported in the literature.

Tunç, Merve T.; Kahyaoglu, Talip
Defatted hazelnut flour (DHF) in different levels (5%, 10% and 15%) of locust bean, guar and xanthan gum were added in rice-based gluten-free formulations to improve rheological properties of dough and baking properties of bread. The rheological characteristics of dough samples were determined by steady flow curves and dynamic tests. The baking properties of breads were evaluated by specific volume, Textural Profile Analysis (TPA) parameters and color values. The rheological measurements showed that all gluten-free dough had pseudoplastic behavior. Specific volume values of breads ranged from 2.20 to 2.83cm3/g. Gum addition enhanced the specific volume of gluten-free breads. Hardness values of gluten-free breads ranged from 1,069.80 to 3,135.88 g and DHF addition of gluten-free formulations caused significant decrease of the hardness values of breads (p < 0.05). DHF addition in gluten-free formulations made bread crumb darker than bread without DHF and gum. DHF addition also increased a and b values of gluten-free bread's crumb.

Dincel, Gungor Cagdas; Atmaca, Hasan Tarik
Toxoplasma gondii (T. gondii) is a protozoan parasite with the potential of causing severe encephalitis among immunocompromised humans and animals. Our previous study showed that T. gondii induces high nitric oxide (NO) production, high glial activation (GFAP) and neurofilament expressions, leading to severe neurodegeneration in toxoplasma encephalitis (TE) in the central nervous system (CNS). The aim of this experimental study was to investigate ADAMTS-13 expression and apoptosis in CNS and to identify whether they have any correlation with toxoplasmosis neuropathology and neurodegeneration. Mice were infected with ME49 strain T. gondii and the levels of ADAMTS-13, caspase 3, caspase 8, caspase 9, TNFR1 and Bcl-xL expressions were examined in brain tissues by immunohistochemistry, during the development and establishment of chronic infections at 10, 30 and 60days post-infection. Results of the study revealed that the levels of ADAMTS-13 (P < 0.005), caspase 3 (P < 0.05), caspase 8 (P < 0.05), caspase 9 (P < 0.005) and TNFR1 (P < 0.05) expressions in the brain markedly increased while Bcl-xL expression decreased (P < 0.005). The most prominent finding from our study was that 10, 30 and 60days post-infection ADAMTS-13 increased significantly and this may play an important role in the regulation and protection of the blood-brain barrier integrity and CNS microenvironment in TE. These results also suggest that T. gondii-mediated apoptosis might play a pivotal role and a different type of role in the mechanism of neurodegeneration and neuropathology in the process of TE. Furthermore, expression of ADAMTS-13 might give an idea of the progress and is critical for diagnosis of this disease. To the best of the authors' knowledge, this is the first report on ADAMTS-13 expression in the CNS of T. gondii-infected mice.

Özbek, Mehmet Ferhat; Yoldash, Mohammad Asif; Tang, Thomas Li-Ping
Research suggests that organizational justice (procedural, distributive, and interactional justice) has important impacts on work-related attitudes and behaviors, such as organizational citizenship behavior (OCB). In this article, we explore the extent to which individualism moderates the relationship between organizational justice and OCB (organizational obedience, participation, and loyalty) among citizens in Kyrgyzstan. We make additional contributions to the literature because we know very little about these constructs in this former Soviet Union country, Kyrgyzstan, an under-researched and under-represented region of the world. Results of our data collected from 402 managers and employees in Kyrgyzstan offer the following new discoveries. All three justice constructs are related to OCB. Individualism moderates only the distributive and interactive justice to OCB relationships. We develop an intricate theory with provocative implications: Procedural justice produces obedience. For “individualists,” interactional justice inspires loyalty and, interestingly, distributive justice “can only buy” participation, but “can’t buy” loyalty. Therefore, for individualists, interactional justice outweighs distributive justice for organizational loyalty. Based on Kyrgyz citizens’ justice, OCB, and individualism, our theory reveals novel insights regarding culture, money attitude, and intrinsic motivation and provides critical and practical implications to the field of business ethics.

Simsek, Cemaleddin; Turk, Kadir
As the first theoretically proven capacity-achieving error correction code, polar codes have become a milestone in information theory field, which draw serious attention by its low complexity encoding and decoding structures. For the decoding section, studies are focused on efficient and low complex algorithms based on successive cancellation and belief-propagation (BP) decoders. To reduce computational complexity of BP-based decoders further, early stopping methods that avoid unnecessary iterations can be used. In this letter, we propose a reduced complexity early stopping method for BP-based polar code decoders. The proposed method is based on the hypothesis that observing only a small cluster of information bits polarized to the highest error probabilities is enough to detect successful decoding. Simulation results show that the proposed early stopping criterion significantly reduces the computational complexity of successful decoding detection as well as the total operation numbers of the whole decoding process compared with previous methods in the literature.

Seismic response characteristics of structures can be estimated by spectral ratios of microtremors measured on structures and their foundation ground surface. The microtremor horizontal-To-verticalspectral- ratio (HVSR) technique has received great attention from all over the world with its simplicity together with quick information about dynamic characteristics of ground and structures. The HVSR of microtremors gives a good estimation of natural building frequency. In this study, Horizontal-To-Vertical- Spectral-Ratio HSVR method and Floor Spectral Ratio Method (FSR) has been applied to microtremor records taken with three component broad band velocity seismometers in three different locations inside the building and one at outside with the aim of determining the dynamic characteristics of Faculty building of Law at The Karadeniz Technical University (KTU), in Turkey. The average predominant frequency, period and amplification values for the Faculty building of Law are calculated. The vibration frequency and period is around 3.5 Hz and 0.283 s, respectively. The amplitude values increase to the upper floors.

Karsli, Orhan; Dokuz, Abdurrahman; Kandemir, Raif
Late Carboniferous to early Permian granitoid rocks represent a volumetrically minor component of the Eastern Pontide lithosphere, but they preserve useful information about the region's tectonomagmatic history. The Casurluk and Camlik plutons primarily consist of gabbro, gabbroic diorite, diorite, monzogabbro, monzodiorite and monzonite, which intrude early to middle Carboniferous granitic basement rocks in the region. In this study, we use in situ zircon U–Pb ages and Lu–Hf isotopic values, whole-rock Sr–Nd isotopic values, and mineral chemistry and geochemistry of these plutons to determine petrogenesis and crustal evolution; we also discuss geodynamic implications. LA–ICP-MS zircon U–Pb dating of magmatic zircons from the rocks suggests that the plutons were emplaced during the late Carboniferous to early Permian (302 Ma). The metaluminous and I-type intrusive rocks belong to the high-K calc-alkaline series. In addition, they are relatively enriched in light rare earth elements (LREEs) and large-ion lithophile elements (LILEs); they are depleted in heavy rare earth elements (HREEs) and high field strength elements (HFSEs), such as Nb and Ti. All of the samples have homogeneous initial ISr values (0.70675 to 0.70792) and low εNd (t) values (− 5.1 to − 3.3). Zircons from the rocks of both plutons have uniform negative to slightly positive εHf (t) values (− 3.5 to 1.4) and old Hf two-stage model ages (1323 to 1548 Ma), implying that they have the same source, as well as suggesting the involvement of old enriched lithospheric mantle materials during their magma genesis. These results, combined with the εHf (t) values and two-stage model ages, demonstrate that the primary magmas were derived from partial melting of old lithospheric mantle material metasomatized by subduction-related fluids. Considering other regional geological data from the Sakarya Zone where these plutons formed, we conclude that late Carboniferous to early Permian magmatism in the area involved the partial melting of a phlogopite- and spinel-bearing lherzolite under an extensional regime in a subduction-related setting. Such an extension event would have caused hot asthenospheric upwelling and was likely triggered by back-arc rifting during subduction of the Paleo-Tethyan oceanic slab. Thus, the magmas are likely subduction-related products, implying that southward subduction of Paleo-Tethys oceanic lithosphere in the region began during the late Carboniferous to early Permian.

Çelik, Ilhan
Titanium and its alloys are widely used as materials for bio-medical applications, such as implants. However, ions of the alloy can release to the body region and spread into the blood circulation. In this study, plasma nitriding and CrN coating techniques are used in order to overcome the problem of ion release. The objective of this study was to investigate the effects of plasma nitrided pure titanium on the structural properties and corrosion behaviors before and after CrN coating in Ringer's solution at 37 °C. The structural properties were investigated using Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). A diffusion layer and a compound layer composed of δ-TiN and ε-Ti2N phases were observed on the surface of nitrided pure titanium. Corrosion tests were made for the determination of electrochemical properties with the help of Potentiostat/Galvanostat device. The results show that corrosion behaviors of untreated and treated samples have similar characteristic.

Shorelines are complex ecosystems and vital socio-economic environments. They may change rapidly due to both natural and human-induced effects. Determination of movements along the shoreline and monitoring of the changes are indispensable for many purposes such as coastline management, agriculture, decision support systems etc. Thus, rapid, up-to-date and accurate information are required to monitor the shorelines. In this study, the Kestel Dam Lake has been selected for evaluation and testing of the methods which will be used for the research project, about shoreline extraction with use of UAV-Based LIDAR data in the region of Terkos-Istanbul, which supported by TUBITAK (The Scientific and Technological Research Council of Turkey) with project nr. 115-718. Kestel Dam is located on the river of Kestel that is constructed for the irrigation purposes, built between 1983 and 1988. Irrigation capacity of dam is about 4077 ha of agricultural areas. The used dataset is LIDAR data which is provided by HGK (Turkish General Command of Mapping). In this study, two different methods are applied with use of LIDAR data, acquired in 2013. One method is mean-shift segmentation and the other is Particle Swarm Optimization Analysis (PSO). The results are both compared with manually created reference vector dataset which is created using orthoimage dataset. The results shows that the developed methods have potential to give success in the research project which will be performed in the region of Terkos which is the study area of the project.
AtıfScopus4İncele - MakaleYalnız künye2016Scopus SJRQ1U–Pb zircon chronology and petrogenesis of Carboniferous plutons in the northern part of the Eastern Pontides, NE Turkey: Constraints for Paleozoic magmatism and geodynamic evolution
Kaygusuz, Abdullah; Arslan, Mehmet; Sipahi, Ferkan; Temizel, İrfan
Numerous intrusive rocks of varying ages and compositions exist in the Paleozoic to Tertiary periods in the Eastern Pontides. Carboniferous intrusive rocks are commonly observed in the southern part of the Eastern Pontides. The nature of the rocks in the northern part of the region has not been determined because of Upper Cretaceous and Tertiary volcano-sedimentary units. Whole-rock geochemical, isotopic and geochronological data obtained from five different mapped granitoid bodies located in the northern part of the Eastern Pontides allow for the proper reconstruction of Carboniferous magmatism and the geodynamic evolution of the region. According to laser ablation ICP-MS U–Pb zircon dating, the Özdil, Soğuksu, Seslikaya, Kızılağaç and Şahmetlik plutons have similar 206Pb/238U vs. 207Pb/235U concordia ages of 340.7 ± 1.8 Ma and 323.1 ± 1.5 Ma, 348.4 ± 1.6 Ma, 335.4 ± 1.4 Ma, 337.2 ± 0.6 Ma and 334.5 ± 1.4 Ma, respectively. The aluminium saturation index (ASI) values of all of the samples from the plutons are between 1.0 and 1.32, which indicate peraluminous melt compositions. The plutons have SiO2 contents between 59 and 79 wt.% and show low- to high-K calc-alkaline characteristics. The plutons are enriched in large-ion lithophile and light rare earth elements and are depleted in high-field strength elements. Chondrite-normalized rare earth element patterns are characterized by concave-upward shapes and pronounced negative Eu anomalies, with LaCN/YbCN = 1.9–46.8 and EuCN/Eu* = 0.19–1.76. The studied plutons show considerable variations in 87Sr/86Sr(i) (0.70255 to 0.71006) and εNd(i) values (− 4.8 to − 7.1), as well as Nd model ages (1.15 to 2.47 Ga). The Pb-isotopic ratios are 206Pb/204Pb = 17.11–18.60, 207Pb/204Pb = 15.58–15.64 and 208Pb/204Pb = 36.95–38.62. The crystallization temperatures of the melts range from 676 to 993 °C, as determined by zircon and apatite saturation thermometry. These data suggest that the Carboniferous granitic magmas were produced by the partial melting of meta-mafic to meta-felsic lower crustal source rocks, with minor contributions from the mantle. Collectively, these rocks represent a late stage of Hercynian magmatism in the northern part of the Eastern Pontides.

Alemdag, S.; Gurocak, Z.; Cevik, A.; Cabalar, A.F.; Gokceoglu, C.
This paper investigates a series of experimental results and numerical simulations employed to estimate the deformation modulus of a stratified rock mass. The deformation modulus of rock mass has a significant importance for some applications in engineering geology and geotechnical projects including foundation, slope, and tunnel designs. Deformation modulus of a rock mass can be determined using large scale in-situ tests. This large scale sophisticated in-situ testing equipments are sometimes difficult to install, plus time consuming to be employed in the field. Therefore, this study aims to estimate indirectly the deformation modulus values via empirical methods such as the neural network, neuro fuzzy and genetic programming approaches. A series of analyses have been developed for correlating various relationships between the deformation modulus of rock mass, rock mass rating, rock quality designation, uniaxial compressive strength, and elasticity modulus of intact rock parameters. The performance capacities of proposed models are assessed and found as quite satisfactory. At the completion of a comparative study on the accuracy of models, in the results, it is seen that overall genetic programming models yielded more precise results than neural network and neuro fuzzy models.

Aydin, Sinan; Akkan, Yaşar
Mathematical objects are ʼnatural objects’ for the practical mind. Definitions and theories can only describe them, not create or construct them. A mathematical term is interpreted through its denotation as representing a collection of particular objects for the theoretical mind. So, theoretical and practical modes of thinking differ in the manner in which they constitute the meanings of words. Thinking in terms of prototypical examples, rather than definitions, became an obstacle to our students’ understanding the notion of linear transformation. In the course, linear transformations were defined as transformations of vector spaces which conserve linear combinations. The obstacle was revealed in the students’ attempts ‘linear extension problem’: given a transformation of a basis, to construct a linear transformation with those values on the basis. In the experimental course, the problem was not formulated in such general terms. It was restricted to two dimensions, and the students were not asked to ‘linearly extend a transformation from a basis to the whole plane’ but to assume the existence of such an extension and find some missing information about it. In this study we are discussing students understanding of mathematical concepts by means of linear transformation in linear algebra.

Özturk, S.; Sari, M.
A statistical assessment of recent seismicity in the North Anatolian Fault Zone, Turkey, is made by using seismotectonic b-value and precursory seismic quiescence Z-value. The catalogue including 28,420 earthquakes between 1970 and 2016 is used. Using the Reasenberg declustering process and the earthquakes with MD≥2.7, 51.4% of the events are removed and so, 13,815 events are used for a quantitative evaluation of seismic quiescence in the NAFZ in the beginning of 2016. Completeness magnitude is estimated as 2.7. Resulting values show that significant anomalies are observed in both band Z-values in some parts of the NAFZ. The larger b-values are calculated in Silivri, Black Sea, Izmit and Düzce whereas the smaller b-values are estimated in the western, the eastern and the middle parts of the NAFZ, covering Gulf of Saros, Gelibolu (Çanakkale), Ismetpasa segment, Bingöl, Erzincan, Amasya and Çankiri. Several quiescence regions in and around Tekirdag, Gulf of Saros, Istanbul, Marmara and Black Sea, Izmit, Düzce fault, Mudurnu, Çankiri, Amasya are observed. Consequently, the same regions including Gulf of Saros, Çankiri and Amasya where the smallest b-values and the largest Z-values are obtained may give important evidences to reveal the future earthquake potential in the North Anatolian Fault Zone.
