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 ...
Earthquake hazard assessment for different regions in and around Turkey based on Gutenberg-Richter parameters by the Least Square Method
(Journal of Applied Functional Analysis, 2009)
In this study, we made an assessment of earthquake hazard parameters for different 24 source regions in and around Turkey. We used the seismic source zones and the database defined by Bayrak et al. [12] and Bayrak et al. ...
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 ...
