K/Ar ages and geochemistry of the post-collisional volcanic rocks in the Ilica (Erzurum) area, eastern Turkey
(E Schweizerbartsche Verlagsbuchhandlung, 2009)
The Neogene Ilica volcanics in eastern Anatolia are of sub-alkaline affinity and present features of post-collisional volcanism. The lava flows in the Ilica area reveal K/Ar ages ranging from 13.9 +/- 0.5 to 4.4 +/- 0.3 ...
Stochastic finite element analysis of structural systems with partially restrained connections subjected to seismic loads
(Techno-Press, 2009)
The present paper investigates the stochastic seismic responses of steel Structure systems with Partially Restrained (PR) connections-by using Perturbation based Stochastic Finite Element (PSFEM) method. A stiffness matrix ...

Complete flux jumping in nano-structured MgB2 superconductors prepared by mechanical alloying
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009-07-08)
High density nano-crystalline MgB2 bulk superconductors with induced pinning centres were prepared from elemental precursors by a sequence of ball milling, heat treatment, and final pressing. The XRD results revealed the ...
Effects of the Stroke Bore Ratio on the Performance Parameters of a Dual-Spark-Ignition (DSI) Engine
(Energy & Fuels (ACS Publishers), 2009)
In this study, the effects of the stroke/bore (S/B) ratio on the performance parameters of an engine having dual-spark ignition (DSI) were investigated theoretically by using a quasi-dimensional thermodynamic cycle model. ...
Estimating earthquake hazard parameters from instrumental data for different regions in and around Turkey
(Engineering Geology, 2009)
We conducted a study of the spatial distributions of seismicity and earthquake hazard parameters for Turkey and the adjacent areas, applying the maximum likelihood method. The procedure allows for the use of either historical ...
Fabrication and properties of dense ex situ magnesium diboride bulk material synthesized using spark plasma sintering
(IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009-09)
High density ex situ magnesium diboride bulks were synthesized from commercial MgB(2) powder using spark plasma sintering under a range of applied uniaxial pressures between 16 and 80 MPa. The microstructure was characterized ...
Exergetic Analysis of Using Oxygenated Fuels in Spark-Ignition (SI) Engines
(Energy & Fuels (ACS Publications), 2009)
In this study, the use of the oxygenated fuels in spark-ignition (SI) engines has been investigated by means of exergy analysis. For this purpose, a two-zone quasi-dimensional thermodynamic cycle model was used. The cycle ...
Comparison of levitation force relative to thickness of disk shaped YBa2Cu3O7-x prepared by MPMG and FQMG processes
(ELSEVIER SCIENCE SA, PO BOX 564, 1001 LAUSANNE, SWITZERLAND, 2009-11-20)
The precursor YBCO in the stoichiometric ratio of 1:23 were fabricated using the melt-powder-melt-growth (MPMG) technique, and flame-quench-melt-growth (FQMG) technique. The superconducting regions were determined by ...
AC loss study by AC susceptibility measurement in a commercial Bi:2223/Ag tape prepared by the CTFF method: H // c axis and short specimen
(IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009-12-23)
The effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape prepared by the continuous filling and forming (CTFF) method has been investigated. The ...
