We study the sensitivity of anomalous ZZγ and Zγγ vertex couplings h3γ,Z and h4γ,Z, which would be a powerful sign of new physics, via the subprocess γq→Zq of the main reaction pp→pγp→ZqX at the LHC. We calculated limits on these couplings at 95% confidence level for various values of integrated luminosity. It is shown that the pp→pγp→ZqX reaction provides 1 order of magnitude improvement in the couplings h4γ,Z compared to the current experimental limits obtained in events dominated by Zγ production from the LHC and Tevatron. © 2013 American Physical Society.

The discovery of Higgs boson plays a crucial role in understanding the electroweak symmetry breaking sector. From now on, solving the dynamics of this sector needs precision measurements of the couplings of the Higgs boson to the Standard Model particles. In this work, we investigate the constrains on the anomalous HWW and HWWγ couplings, described by the dimension-six operators in the effective Lagrangian, in a high energy envisaged ep collider which is called Large Hadron electron Collider (LHeC). We obtained the 95% confidence level limits on the couplings of anomalous HWW and HWWγ vertex, with the design luminosity of 10fb-1 and electron beam energy of 140 GeV, through ep→νH+X, γp→WH+X and eγ→WHν processes by considering the new physics energy scale to be Λ=1TeV. The sensitivity of the LHeC to the new physics scale is also briefly discussed. © 2013 Elsevier B.V.


Fine and small roots of trees are an important part of the terrestrial carbon (C) cycle because they comprise a large fraction of annual net primary production and as ephemeral tissues they are returned to the soil on relatively short time scales. Their decomposition in soil can play an essential role for nutrient cycling and organic matter turnover within ecosystems that are important determinants of plant productivity and ecosystem carbon (C) storage. However, the processes and factors influencing the fine-root decomposition rates in forest ecosystems has been studied less than that of litter shed from the above ground parts of trees. In the present study, we therefore investigated the effects of tree species, topography and soil depth on the decomposition rates of fine and small roots using alder (. Alnus glutinosa L.), Oriental spruce (. Picea orientalis L.) and pine (. Pinus sylvestris L.) tree species. The root samples collected from two aspects (north and south) and two altitudes (900. m and 1260) on each aspect, and were placed into 0-10. cm and 10-20. cm of soil depth. Standard root samples were also placed on the same sites in order to evaluate the effects of microclimate on the root decomposition rates. Alder roots showed the highest decomposition rates, followed by pine and Oriental spruce roots. For each tree species, the root samples placed on south aspect and at lower slope on each aspect decayed faster than that on north aspect and at higher slope. The root decomposition rates decreased with increasing root thickness and soil depth. Among the tree species, initial root litter quality (especially C:N ratio) played an important role on their decomposition rates. In addition to litter quality factor, air temperature in open area and under the stands affected decomposition rates of the standard root samples. © 2014 Elsevier B.V.

In the APEX (Advanced Power Extraction) studies, the conventional first solid wall facing the plasma is replaced with a fast flowing layer of a thin liquid wall. The concept of a free-surface first liquid wall concept is a revolutionary concept. The first liquid wall flows very fast and detains charged particles, and is followed by the thick liquid wall (blanket) which flows slowly and absorbs generated energy and converts it to heat. In the study, the flowing molten salt (i.e., first wall and blanket) is composed of Flibe (Li2BeF4) and is considered the main constituent mixed with different mole fractions (0-12%) of heavy metal salt (ThF4 or UF4) to increase the energy multiplication. Self-sufficient tritium breeding ratio (TBR>1.05) was taken into account to determine the upper limit of the fraction of heavy metal salt in the mixture. Design and calculations of APEX were carried out as 3-D torus by using MCNP-4B computer code. © 2011 John Wiley & Sons, Ltd.

We have examined nonstandard γνν̄ and γγν ν̄ couplings via νν̄ production in eγ and γγ collisions at the Compact Linear Collider (CLIC). We obtain 95% confidence level bounds on γνν̄ and γγνν ̄ couplings by considering the backscattered photon distribution function for incoming photons and initial state radiation and beamstrahlung effect for initial state electrons in the eγ and γγ collider modes of the linear collider. We indicate that the reaction γγ→νν ̄ provides more than 15 orders of magnitude improvement in neutrino-two photon couplings compared to LEP limits. © 2012 American Physical Society.

From ancient civilisations to the present, the underground and aboveground sites at Pompeipolis have reflected the social, economic, and cultural characteristics of the surrounding region and been a marker of its archaeological and natural heritage. This area should be passed on to future generations of humanity; to promote the protection of this site, promotional activities should be planned that use it in the best way. In this study, I evaluate the potential for the caretakers of the ancient city of Pompeipolis within Kastamonu to establish modern conservation approaches, balance its conservation and use within the framework of cultural tourism, and determine problem areas and opportunities. This framework is intended to establish a continuity of forward-looking tourism. In the context of the Kastamonu archaeological sites and the data obtained from studies conducted in the immediate vicinity, and by evaluating research studies and the literature, I will demonstrate the problems and opportunities that may be encountered while preserving the original character of the area. This will ensure its protection, balance, and sustainability, as well as conducting landscape design and developing tourism activities in the area. © 2015 Taylor and Francis.

It should be possible, for a city, to achieve a healthy environment, an active green space, and an urban distribution of the size of a systematic planning of functional and aesthetic qualities, and it will be possible with the development of an urban design concept. The adequacy of the standard value of green space is usually specified in the relevant legislation, and the current per capita of the city is identified by comparing it to the amount of green space. In this study, the distribution and amount of green space in Kutahya is examined as well as the distribution of green areas on a neighbourhood scale. Size and per capita rates are evaluated. Even distribution of the distance and accessibility of green areas throughout the city are closely related to the provision of recreational needs. Different sizes of green area, recreational activities, and accessibility standards vary depending on the city unit they serve. According to the digitization of parks composed of polygons in the ArcGIS attribute table for calculation, parks in the study area consist of 167 different parcels, 48 of which (28%) are 1500 m2 or less in area. Most small parklands were 306 m2; the largest urban park is at the southern entrance of the city, with an area of 109.214 m2. Parks in the study area cover a total area of 614.272 m2. Functionally linked, an integrated system of green spaces will allow the city to develop this natural potential in a sustainable way. © 2015 Taylor and Francis.


In this study, rapidly solidified hypereutectic Al-20Si-5Fe-XV (X = 0, 0.5, 1 and 1.5) alloys were fabricated by gas atomization in Ar atmosphere. Microstructural and spectroscopic analyses were performed using SEM, SEM - EDS and XRD measurements. Experimental results showed that addition of V to gas-atomized Al-20Si-5Fe alloys led to formation of a refined microstructure composed of finer Si and Fe-bearing intermetallics. Possible refining mechanism of Si phases is the IIT because of Rv:RSi is 1.38 close to the value of 1.65 which is the ideal ratio of radius for the impurity-atom to Si-atom (Ri:RSi). The reason of formation finer of δ-Al4FeSi2 phase with addition of V is that vanadium addition leads to an increment in the thermodynamic stability and a reduction in the free energy of δ-Al4FeSi2 phase. Therefore, finer and modified morphology became more favorable for δ-Al 4FeSi2 phase in terms of thermodynamic. Nanosize Si particles growing on the surface of Fe-bearing intermetallics and micro size polygonal Si phases were observed. There was no effect of V on the number of fine silicon particles growing up on the micro size polygonal Si phases. However, during solidification, addition of V led to an increase in the number of fine silicon particles growing on the Fe-bearing intermetallics. Microhardness measurements showed that there was an increase in the microhardness values of Al-20Si-5Fe alloys with addition of V, in general. ©2014 Elsevier B.V. All rights reserved.

We analyze the anomalous quartic gauge boson couplings WW λ λand ZZ, λ λ described by dimension-six effective quartic Lagrangian at the LHC. The sensitivities to anomalous quartic gauge couplings aW,Z 0,c /δ2 by examining the two different photon-induced processes pp → pγp → pWqX and pγp → pp → pZZqX with W and Z's decaying leptonically are investigated. We show that p mode of photon-induced reactions at the LHC are able to probe these couplings to the order of 10-6-10-7 GeV-2 at 95% confidence level (C.L.) with √s = 14 TeV and for proton-proton luminosities in the range of 30-200 fb-1. © World Scientific Publishing Company.

In this study we have investigated the influence of iron diffusion and diffusion-annealing time on the mechanical and the superconducting properties of bulk Bi 1.8Pb 0.35Sr 1.9Ca 2.1Cu 3O y superconductors by performing X-ray diffraction (XRD), scanning electron microscopy (SEM), Vickers hardness, dc resistivity ( p-T) and critical current density (J c) measurements. The samples are prepared by the conventional solid-state reaction method. Doping of Bi-2223 was carried out by means of iron diffusion during sintering from an evaporated iron film on pellets. Then, the Fe layered superconducting samples were annealed at 830 ©C for 10, 30 and 60 h. The mechanical properties of the compounds have been investigated by measuring the Vickers hardness (Hv). The mechanical properties of the samples were found to be load dependent. The load independent Vickers hardness (H0), Young'smodulus (E), yield strength (Y), and fracture toughness (K IC) values of the samples are calculated. These all measurements showed that the values of the Vickers hardness, critical current density, and critical transition temperature and lattice parameter c increased with increasing Fe doping and diffusion-annealing time. © 2011 Springer Science+Business Media, LLC.
