Acar, Irfan; Arslan, Tayfun; Topçu, Saim; Aktaş, Ayşe; Şen, Serkan; Serencam, Hüseyin
In this study, metallophthalocyanines 4, 5, 6 was carried out by the cyclotetramerization of 4-{3-[(2E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoyl] phenoxy}phthalonitrile 3. The synthesis of metallo derivatives [Zn(II), Co(II), Cu(II)] of phthalocyanines obtained from corresponding phthalonitrile derivative and in the presence of the anhydrous divalent metal salts (Zn(CH 3COO)2, CoCl2 and CuCl2) was described. These phthalocyanines showed good solubility in organic solvents such as chloroform, tetrahydrofuran, DMSO and DMF. The newly synthesized Pcs were verified by IR, 1H NMR, 13C NMR, UV-vis and MS spectral data. The electrochemical properties of the zinc(II), copper(II) and cobalt(II) phthalocyanines were investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. The cobalt complex showed a metal based reduction process, while zinc phthalocyanines were giving ligand based electron transfer processes.

Erdem, O.; Ozturk, K.; Guner, S.B.; Celik, S.; Yanmaz, E.
The levitation properties of MgB2 prepared by hot press at 200 ° C and then pellet/closed tube method has been investigated. The vertical and lateral levitation forces (Fz and Fx) on a cylindrical NdFeB permanent magnet (PM) below a disk-shaped bulk MgB2 were measured during the vertical and lateral traverses of the PM in different cooling heights (CHs) and measurement heights (MHs) at temperatures of 20, 25 and 30 K to investigate the effect of the initial CH and MH on the levitation performance of MgB2. For temperatures below 30 K, it was observed that Fz increases with increasing CH. However, a minute variation in Fz and a big hysteresis loop are observed at 30 K. From the lateral traverses, it was obtained that the Fz with attractive character increases with decreasing MH and the hysteresis effect increases for small MHs due to the increment of the magnetic field intensity which the sample feels with decreasing MH. In addition, it was seen that the character of Fx varies depending on both MH and measurement temperature. The higher hysteresis obtained in Fx than in Fz during lateral traverses implies that the motion of the flux lines in MgB2 is especially in lateral rather than vertical direction. Finally in this study, it was shown that the levitation performance of MgB2 depends not only on the measurement temperature but also on the CH and MH conditions. These results can be useful for optimizing the levitation performance of MgB2 superconductors for potential applications.

Çakır, Uğur; Şahin, Erol
This study is a research made on evaluating solar energy utilization rates of the buildings and residences which are under the climatic and meteorological conditions of Bayburt. In the scope of this study, with the aim of enabling them to benefit from solar energy at the maximum level, a numerical modeling study in which we could determine the most suitable directions, shapes, and sizes of the buildings that would be built in Bayburt was carried out. Although the modeling was applied for sample buildings that have specific sizes and shapes and some results were obtained, this modeling can be used for other buildings which have different shapes and the most suitable direction and location designation that can be done. In the solar energy analysis made for the buildings, a year time was divided into four different periods. Related evaluations were made by taking into account that the building should be in shape and orientation which takes the maximum and minimum radiance in the summer and winter. Basic parameters were determined as azimuth angle, the ratio of the building length to its width, and the total periodical radiance that the building takes.

Kansu, Ceren Çevik; Öksüz, Yücel
The purpose of the present paper is to develop a scale for assessing behaviours towards active citizenship for 4th grade primary school students. The proposal scale, composed of 42 items, was applied to 544 students who are studying at 4th grade of primary schools in the centre of Bayburt. The principal component analysis rotated by varimax rotation was used to obtain evidence for validity of the scale. As a result of this analysis, it has been determined that the scale consists of 25 items and it has a structure composed of four factors. Evidence for validity of the item, item test correlation of the scale and item analysis of the mean differences between upper and lower groups were calculated. It was observed that item test correlation of the scale changed between 0.42-0.74. Besides, Cr α reliabilities were calculated and it was found to be 0.85.

Hasar, Ugur Cem; Bute, Musa; Barroso, Joaquim J.; Sabah, Cumali; Kaya, Yunus; Ertugrul, Mehmet
In this paper, we analyze wave propagation properties (transmitted, reflected, and absorbed powers) of composite multilayer structures consisting of bi-anisotropic metamaterial (MM) slabs and conventional isotropic materials. We also separately investigate the propagation properties of bi-anisotropicMMslabs and conventional materials to better interpret the results. We consider two different bi-anisotropic MM slab structures composed of only splitring- resonators (SRRs) and composing SRRs and a rod. In the analysis, we apply the well-known transfer matrix method to obtain transmitted, reflected, and absorbed powers of the composite structures. From the analysis, we note the following three important results. First, while the transmitted powers from forward and backward directions of the multilayer structure are identical (reciprocal feature), reflected (and absorbed) powers from forward and backward directions of the multilayer structure are different. This difference arises from reflection asymmetric nature of the bi-anisotropic MM slabs. Second, whereas the conventional material loss influences propagation characteristics aside resonance frequencies of bi-anisotropic MM slabs, bi-anisotropic MM loss worsens propagation properties of the multilayer structure at resonance frequencies of these slabs. Third, variations in (or determination of) electromagnetic properties of low-loss thin conventional materials in between two bi-anisotropic MM slabs can be realized at frequencies in which conventional materials demonstrate thickness-resonance effect.

Öner, Erdal; Birinci, Ahmet
The continuous contact problem for two elastic layers resting on an elastic half-infinite plane and loaded by means of a rigid stamp is presented. The elastic layers have different heights and elastic constants. An external load is applied to the upper elastic layer by means of a rigid stamp. The problem is solved under the assumptions that all surfaces are frictionless, body forces of elastic layers are taken into account, and only compressive normal tractions can be transmitted through the interfaces. General expressions of stresses and displacements are obtained by using the fundamental equations of the theory of elasticity and the integral transform technique. Substituting the stress and the displacement expressions into the boundary conditions, the problem is reduced to a singular integral equation, in which the function of contact stresses under the rigid stamp is unknown. The integral equation is solved numerically by making use of the appropriate Gauss-Chebyshev integration formula for circular and rectangular stamp profiles. The contact stresses under the rigid stamp, contact areas, initial separation loads, and initial separation distances between the two elastic layers and the lower-layer elastic half-infinite plane are obtained numerically for various dimensionless quantities and shown in graphics and tables.

Satureja hortensis L. (Lamiaceae) has been used as a folk remedy to treat various such as cramps, muscle pains, nausea, indigestion, diarrhea, and infectious diseases. In this study, the antagonistic effects of essential oil of S. hortensis (SHE) were studied against aflatoxin B1 (AFB1) in human lymphocytes in vitro. The analysis of the essential oil was performed by using Gas chromatography-mass spectrometry (GC-MS). Anti-genotoxic effects of the SHEs was evaluated using sister chromatid exchange (SCE), micronuclei (MN) tests against AFB1. Also level of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities used to determine the anti-oxidative effects of the SHEs. This result showed AFB1 (5 μM) increased the frequencies of SCE, MN and the level of MDA. AFB1 at the same concentration decreased the activities of SOD and GPx. However, different concentrations of SHE with AFB1 decreased the frequency of SCE and MN and level of MDA and also increased the activities of SOD and GPx significantly. Especially, the 1.0, 1.5, 2.0 μL dose of SHE are more effective than other doses. The results of this experiment have clearly shown that SHE has strong antioxidative and antigenotoxic effects, these biological activities of SHEs can be due to its component.

Increasing consumer demands for indigenous, non-sprayed with pesticides and less-known or “forgotten” fruits necessitate knowledge on their breeding, cultivation, biochemical content, harvesting and marketing. Anatolia is rich for wild edible fruit species and barberry is abundant throughout Anatolia. The aim of this study was to determine some important physicochemical characteristics, bioactive content and antioxidant capacity of fruits from nineteen promising barberry (Berberis vulgaris L.) genotypes grown in the Coruh valley, Northeastern Anatolia. The results indicated genotype-specific differences for most of the physicochemical characteristics, antioxidant capacity and the content of some bioactive compounds. Fruit mass ranged from 0.073 (‘Coruh-7’) to 0.267 g (‘Coruh-11’). Total phenolic content ranged from 2532 (‘Coruh-’) to 3719 mg GAE per liter fruit juice (‘Coruh-11’). The genotype ‘Coruh-12’ had the highest total monomeric anthocyanin content (1004 mg per liter fruit juice) as cyanidin-3-glucoside. The highest total antioxidant capacity was observed in fruits of ‘Coruh-8’ and ‘Coruh-9’ genotypes with all three antioxidant-determining methods. We conclude that the barberry fruits represent a good source of bioactive phytochemicals because of their high phenolic and anthocyanin contents.

Dereli, Türkay; Altuntas, Serkan; Kubat, C.; Cagil, G.; Uygun, O.
Examination of the relations among firms with respect to knowledge flows is essential for sustainable development and creative economy in global competition as well as for governments, investors and decision makers. Knowing the causal relations among firms provides answers to questions such as: (1) which firms have strong associations? (2) which firms are in the cause group and (3) which firms are in the effect group? The knowledge flow among firms shows the relations among firms directly. Patent citation analysis is extensively conducted to measure the knowledge flow in the literature. The decision making trial and evaluation laboratory (DEMATEL) method is also extensively used to construct causal relations among variables. In this study, the DEMATEL method based patent citation analysis is utilized to construct causal relations among firms. An illustrative example is presented to find relations among firms which operate business method technologies. The results of the example show that the DEMATEL based patent citation analysis can be performed to construct causal relations among firms.

The main object of this study is to determine and compare the structural behavior of base isolated long span highway bridge, Gülburnu Highway Bridge, using single concave friction pendulum (SCFP) and triple concave friction pendulum (TCFP). The bridge is seismically isolated in the design phase to increase the main period and reduce the horizontal forces with moments using SCFP bearings. In the content of the paper, firstly three dimensional finite element model (FEM) of the bridge is constituted using project drawings by SAP2000 software. The dynamic characteristics such as natural frequencies and periods, and the structural response such as displacements, axial forces, shear forces and torsional moments are attained from the modal and dynamic analyses. After, FEM of the bridge is updated using TCFP and the analyses are performed. At the end of the study, the dynamic characteristics and internal forces are compared with each other to extract the TCFP effect. To emphasize the base isolation effect, the non-isolated structural analysis results are added to graphics. The predominant frequencies of bridge non-isolated, isolated with SCFP and isolated with TCFP conditions decreased from 0.849Hz to 0.497Hz and 0.338Hz, respectively. The maximum vertical displacements are obtained as 57cm, 54cm and 44cm for non-isolated, isolated with SCFP and isolated with TCFP conditions, respectively. The maximum vertical displacement reduction between isolated with TCFP bearing and isolated with SCFP bearing bridge is %23. Maximum axial forces are obtained as 60619kN, 18728kN and 7382kN, maximum shear forces are obtained as 23408kN, 17913kN and 16249kN and maximum torsional moments are obtained as 24020kNm, 7619kNm and 3840kNm for non-isolated, isolated with SCFP and isolated with TCFP conditions, respectively.

Son yıllarda pazarda aynı ürün grubunda çok fazla sayıda marka olması rekabeti güç ve çetin kılmaktadır. Bu durum ise fiziksel faydalardan çok marka ve değer yaratma gibi soyut kavramların ön plana çıkmasına sebep olmuştur. İşletmeler markalamayı önemli bir rekabet ve farklılık aracı olarak görmüşlerdir. Bunun sonucunda ise marka, farklılık oluşturmada önemli bir faktör olmuştur. Çünkü iyi bir marka ürüne değer katan önemli bir unsurdur. Sürekli çoğalan markalar sayesinde tüketiciler ve markalar arasındaki ilişkiler karmaşık bir hal almıştır. Tüketici sahip olduğu kişisel değerler ile benzer davranışlar sergilemektedir. Buradan hareketle bu çalışmada kişisel değerler ile marka değeri boyutları arasındaki ilişkiler incelenmiştir. Elde edilen sonuçlar, tüketicilerin kişisel değerleri ile marka değeri boyutları arasında anlamlı ilişkiler olduğunu göstermektedir.
