Objectives: This study examined the effectiveness of a six week psychoeducation program on the adherence of patients with Bipolar Affective Disorder. Method: An experimental study was conducted at a mood disorder outpatient clinic in Zonguldak, Turkiye. Participants were randomly assigned to either intervention (n = 35) or control groups (n = 36). Both groups were given pre-tests and post-tests to measure their adherence. In the psychoeducation group, the psychoeducation program was provided for 2 h/week for six weeks. In the control group, standard care and information were provided. Results: After six weeks, the psychoeducation program significantly improved patients' adherence. The treatment adherence rate of the patients in the intervention group increased from 40.0% (14 patients on pre-test), to 86.7% (26 patients on post-test). Meanwhile, the treatment adherence rate of the control group was 38.9% (14 patients) for the pre-test, and 24.2% (8 patients) for the post-test. Conclusion: This controlled trial study demonstrated that a six-week psychoeducation program can be a useful intervention to improve adherence in patients undergoing bipolar affective disorder rehabilitation. More comprehensive mental health outcomes need to be undertaken. Further studies exploring a longer term follow-up are also required. © 2012 Elsevier B.V. All rights reserved.

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.

Renewable Energy | Year: 2010

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.

This paper aims to assess the current and future role of coal in energy strategy of Turkey, and evaluates the compatibility of policies to the EU energy policy and strategy. Coal is regarded as the most important indigenous energy source in Turkey together with hydropower to strengthen the supply security of the country. Turkish government set targets to fully utilize coal reserves of the country in next decades. However, the country is also in the process of becoming an EU Member State, hence, it is expected that the energy policies have to comply with the EU. Moreover, Turkey ratified Kyoto Protocol in 2009, thus the country should limit CO2 emission together with other greenhouse gases. The probable obstacles that Turkey may face due to the utilization of coal were determined as CO2 emissions, lack of technology and application in Carbon Capture and Storage (CCS) and health and safety issues. It is concluded that coal is a very important domestic energy source for Turkey but new policies have to be developed and adopted immediately, and more realistic targets for the country should be set accordingly. © 2011 Elsevier Ltd.

Various studies have been carried out on the effect of microwave-treatment on grinding different types of coal. However, the effect of microwave treatment on grinding coal samples -3.35 mm in size which can be considered to be fine is still under investigation. The purpose of this paper is to make contributions to these studies conducted. In the study, lignite coal samples with pyritic sulphur and 25% structural moisture were crushed below -3.35 mm particle size using jaw and cone crushers and then classified into three different mono size groups by Russel sieve. For a complete removal of the structural moisture from the lignite coal, a microwave application with 600 W needs approximately 35% more energy consumption than that with 850 W. The untreated coal samples and the ones treated with microwave at 850 W were ground for 5, 15, 30, 60, 120 s in a stirred media mill. The breakage rates of microwave-treated coal increased and accordingly the ground products of microwave-treated coal yielded finer particles than -106 μm as compared to untreated coals. The untreated and microwave-treated feed coals of -3350 μm and -1180 μm particle sizes were ground for 2 min in the stirred media mill. It was found that the increases in the rate of weight percentages for -106 μm particle size fraction after 2 min of grinding of untreated and microwave-treated feed coals of -3350 μm and -1180 μm were found to be 15.81% and 2.69%, respectively. Moreover, Hardgrove Index (HGI) test results of lignite coal showed that the HGI index value increased by approximately 23% after microwave treatment with 850 W. © 2010 Elsevier Ltd.

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 | Year: 2012

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.

Energy Policy | Year: 2012

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.

Gold Bulletin | Year: 2011

Novel cycloaurated gold(III) complexes were prepared by using Schiff bases with different substituents. Effects of the synthesized gold(III) complexes and substituent groups on styrene polymerization were investigated. As a result of these investigations, it was observed that gold(III) complexes could not catalyze polymerization reaction without addition of a co-catalyst like NaBAr′ 4 (Ar′=3,5-bis(trifluoromethyl)phenyl). All ligands and complexes were characterized by using 1H nuclear magnetic resonance (NMR), 13C-NMR, LC-MS, elemental analysis and FT-IR techniques. The architecture of the polymer was determined as an atactic or sydiotactic polymer by using 13C-NMR and DSC techniques. Molecular weights of the polymers were analyzed by using gel permeation chromatogram (GPC). © The Author(s) 2011.

We describe the synthesis and characterization of gold clusters embedded into poly (3-hydroxy octanoate-co-3-hydroxy-10-undecenoate) (PHOU), and evaluated the tissue response of the material upon implantation onto muscle tissue (rat). For this aim, PHOU was obtained by Pseudomonas oleovorans from octanoic acid (OA) and 10-undecenoic acid (UA) with a weight ratio of 50:50. The unsaturated co-polyester film in which HAuCl 4 was dispersed was exposed to air at room temperature to produce gold clusters embedded into cross-linked PHOU. The cross-linking kinetics of the gold catalyzed PHOU autoxidation was followed by sol-gel analysis. In vivo tissue reactions of the cross-linked PHOU embedded gold clusters were evaluated by subcutaneous implantation in rats. The rats appeared to be healthy throughout the implantation period. No symptom such as necrosis, abscess or tumor genesis was observed in the vicinity of the implants. Retrieved materials varied in their physical appearance after 6 weeks of implantation. AFM and SEM micrographs of the PHOU containing gold clusters were also taken. © 2010 Springer Science+Business Media B.V.
