Renewable Energy

In Turkey the laws published in recent years succeeded in promoting the utilization of renewable energy for electricity generation. After the publication of Renewable Energy Law on 18 May 2005 in Turkey there occurred a boost in renewable energy projects along with hydropower development. Thus, the economically feasible hydropower potential of Turkey increased 15% and the construction of hydropower plants also increased by a factor of four in 2007 as compared to 2006. From this perspective, this paper was aimed to evaluate the small hydropower potential of municipal water supply dams of Turkey and discussed the current situation of SHP plants in terms of the government policy. It is estimated that the installing small hydropower plants to exiting 45 municipal water supply dams in Turkey will generate 173 GWh/year electric energy without effecting the natural environment. For a case study, Zonguldak Ulutan Dam and its water treatment plant has been investigated in detail. © 2010 Elsevier Ltd. All rights reserved. Source

Construction and Building Materials

In this study, the effect of non-ground coal bottom ash (NGCBA) and non-ground granulated blast furnace slag (NGGBFS) on permeability properties regarding durability of concrete is investigated. The mentioned by-products have been used as fine aggregate substitute in the production of concrete. Some permeability-durability tests have been conducted on the specimens produced using these by-product fine aggregates. Tests to be done were chosen as rapid chloride permeability, freezing-thawing and drying-wetting tests. Furthermore, microstructures of these concrete types have been observed. Thus, the effects of chemical, physical and mechanical properties of NGGBFS and NGCBA fine aggregates on the permeability of concrete can be obtained in a much better perspective and discussed easily. The optimum replacement ratio of these by-products as fine aggregate is also attempted to be determined for producing low permeable concrete. Consequently, NGBFS and NGCBA generally increase permeability by increasing porosity due to their physical properties but it can be said that these by-products as fine aggregate can also reduce permeability of concrete due to their chemical and mechanical properties in terms of permeability-durability tests. Therefore, usage of these by product types improves durability properties related to the permeability of concrete. © 2011 Elsevier Ltd. All rights reserved. Source

Instability problems may arise during the construction and operation of tunnels depending on the quality of the rock mass. In particular, determining instability problems at the portals of a tunnel is of utmost importance during excavation and operation of the tunnel. Slope instability and rockfalls are the most frequent instability problems that may be encountered at tunnel portals. Such instability problems can be triggered by dynamic effects such as earthquakes, blasting, etc. This study investigates the stability of the portals of the Dorukhan Tunnel connecting the provinces of Zonguldak and Bolu in the close vicinity of the North Anatolian Fault Zone (NAFZ), which is a well-known strike-slip 1500. km long fault. The effect of an earthquake that may occur in the NAFZ on the extent of failure has also been studied by numerical analyses. In the analyses, a three-dimensional dynamic analysis computer code, based on the finite difference method, has been used. According to results of the dynamic numerical analyses, the Devrek portal was found to be more stable than the Mengen portal. Moreover, it was found that, for acceleration values of dynamic wave higher than 0.5. g, tunnel portal slopes and the areas as far as 20-50. m from the tunnel entrance may suffer serious damage. Wave propagation perpendicular to the tunnel axis was established to cause more damage around the openings and in the portal slopes as wave compared to propagation parallel to the tunnel axis. © 2010 Elsevier Ltd.

Physical Review D - Particles, Fields, Gravitation and Cosmology

We have investigated nonstandard νν̄γ and νν̄γγ couplings via νν̄ production in a γp collision at the LHC. We obtain 95% confidence level bounds on νν̄γ and νν̄γγ couplings by considering three different forward detector acceptances: 0.0015<ξ<0.15, 0.0015<ξ<0.5, and 0.1<ξ<0.5. We show that the reaction pp→pγp→pνν̄qX provides more than eight orders of magnitude improvement in neutrino-two photon couplings compared to LEP limits. © 2012 American Physical Society. Source

Energy Policy

This study aims to explore the availability and potential of renewable energy sources in Turkey as well as assessing related government policies, financial and environmental aspects of renewable energy projects. Turkey is a country which has the highest hydropower, wind and geothermal energy potential among European countries. As a European Union (EU) candidate several incentives were developed in Turkey for electricity generation from renewable energy sources by the enactment of Law No. 5346 in 2005 which was later restructured by Law No. 6094 in 2010. The most important ones are: ease of land acquisition and feed-in-tariffs which promise purchasing of electricity generated and domestic manufacturing of equipment by the private companies with a price of 5.30-9.69 and 0.3-2.55 €c/kWh, respectively, depending on the type of the renewable and the equipment. However, feed-in tariff amounts take reservoir area into account instead of installed capacity for hydroelectric power plants. Moreover, Environmental Impact Assessment (EIA) report is not mandatory for all renewable energy plants. According to the multi-criteria analysis tool developed in this study to evaluate the renewable energy source (RES) technologies the most appropriate renewable energy alternative for Turkey is biomass, simply because of the highest social benefit among others. © 2011 Elsevier Ltd.
