(Pergamon-Elsevier Science Ltd, 2008)The (late syn)-post-collisional magmatic activities of western and northwestern Anatolia are characterized by intrusion of a great number of granitoids. Amongst them, Baklan Granite, located in the southern part of the ... -
Cationic dye (methylene blue) removal from aqueous solution by montmorillonite
(Korean Chemical Society, 2012)Color impurity in industrial effluents pose a significant risk to human health and the environment, so much effort has been expended to degrade them using various methods, including the use of clay minerals as adsorbent. ... -
Investigation of adsorption of the dyestuff astrazon red violet 3rn (basic violet 16) on montmorillonite clay
(Brazilian Soc Chemical Eng, 2014)In this study, color removal by absorption from synthetically prepared wastewater was investigated using montmorillonite clay by adsorption. As dyestuff Astrazon Red Violet 3RN (Basic Violet 16) was used. Experimental ... -
Energy-saving retrofitting of houses in cold climates
(Elsevier Science Bv, 2014)Built environment is a problematic issue from an energy use perspective because an important part of total energy consumption in countries is usually caused by existing buildings. Current buildings stock constructed before ... -
The evolving design of 20th-century apartments in Ankara
(Sage Publications Ltd, 2008)This study analyzes a longitudinal series of Ankara apartment houses using space syntax methodology to uncover the underlying genotype and its transformation over time. The results indicate that transition-space-centred ... -
Discrete singular convolution for buckling analyses of plates and columns
(Techno-Press, 2008)In the present study, the discrete singular convolution (DSC) method is developed for buckling analysis of columns and thin plates having different geometries. Regularized Shannon's delta (RSD) kernel is selected as singular ... -
Heat treatment effects to the fracture splitting parameters of C70S6 connecting rod
(Kaunas Univ Technol, 2014)Crackable connecting rods have been widely used in cars' engines recently. In this method no machining is needed to seperate the connecting rod into two pieces. The main microstructure of the crackable C70S6 steel is ... -
Analysis of performance of night ventilation for residential buildings in hot-humid climates
(Gazi Üniv., 2014)Night ventilation is one of the passive cooling techniques commonly used and various theoretical and experimental studies on this subject are available in the literature. However, the effects of climate change are not taken ... -
Parallel genetic algorithms with dynamic topology using cluster computing
(Unıv Suceava, 2016)A parallel genetic algorithm (PGA) conducts a distributed meta-heuristic search by employing genetic algorithms on more than one subpopulation simultaneously. PGAs migrate a number of individuals between subpopulations ... -
The using of waste phosphogypsum and natural gypsum in adobe stabilization
(Elsevier Sci Ltd, 2008)The best known disadvantages of adobe are its low mechanical properties and poor resistance to water damage. In this research waste phosphogypsum (PG) and natural gypsum were used as stabilization material to improve the ... -
Characterization and electrokinetic properties of montmorillonite
(Bulgarian Acad Science, 2014)The determination of surface properties of montmorillonite clay is an important criterion for establishment of its adsorption ability against anionic and cationic species from wastewaters. In this study, electrokinetic ... -
Adsorption of methyl violet dye a textile industry effluent onto montmorillonite-batch study
(Taylor & Francis Inc, 2014)In this study, methyl violet (MV) dye adsorption from synthetically prepared solutions onto montmorillonite was investigated. Experimental parameters were selected as stirring speed, adsorbent dosage, initial dyestuff ... -
Full factorial design of experiments for boron removal from Colemanite mine wastewater using Purolite S 108 resin
(Bulgarian Acad Science, 2014)Boron pollution has a vital importance in Bigadic boron mine in Turkey because the wastewaters of the mine are stored in a soil dam that threats the underground water quality. In this study the optimization of boron removal ... -
Optimal passive filter design for effective utilization of cables and transformers under non-sinusoidal conditions
(IEEE, 2014)Transformers and cables have overheating and reduced loading capabilities under non-sinusoidal conditions due to the fact that their losses increases with not only rms value but also frequency of the load current. In this ... -
An analysis into the effect of voltage harmonics on the maximum loading capability of transformer
(IEEE, 2014)In this paper, some exemplary cases are presented to show the effect of voltage total harmonic distortion (THDV) and its spectrum on the harmonic loss factors (F-HL and F-HL-(STR)) of the six-pulse rectifiers accompanied ... -
A fixed speed ınduction generator model for unbalanced power flow analysis
(IEEE, 2014)This paper proposes a model of the induction generator for the phase-domain power flow analysis of fixed speed wind turbine generating systems connected to balanced or unbalanced three-phase distribution systems. The ... -
Boron removal from waste water originating in the open pit mines of Bigadic Boron Work by means of reverse osmosis
(Inderscience Enterprises Ltd, 2014)In this study, the base water originating in Simav Open Pit Mine containing the most important reserves of colemanite and ulexite boron minerals, has a boron concentration of 150 +/- 50 mg/L, was treated to maximum 2 mg/L ... -
On the no-load loss of power transformers under voltages with sub-harmonics
(IEEE, 2014)Power transformers are traditionally designed for their utilization in sinusoidal voltage and current conditions. However, the non-linear loads are largely proliferated in the modern power systems. Thus, pcc (point of ...
