C2/c pyroxene phenocrysts from three potassic series in the Neogene alkaline volcanics, NE Turkey: their crystal chemistry with petrogenetic significance as an indicator of P-T conditions
(Springer, 2009)
Chemical and structural data are reported for C2/c pyroxene phenocrysts collected from three potassic series (Group A: basanite-tephrite, Group B: tephrite-phonolitic tephrite, Group C: alkaline basalt-trachybasalt) of the ...
Two-and-Three-Dimensional Crustal Thickness of the Eastern Pontides (NE Turkey)
(Scientific Technical Research Council Turkey-Tubitak, 2009)
The Eastern Pontide orogenic belt is divided into three subzones ( northern, southern and axial zones) based on present lithologies and facies associations. NE-SW-, NW-SE- and E-W-trending fault systems, which play an ...
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 ...
Multiobjective optimization of laminated composite cylindrical shells for maximum frequency and buckling load
(Elsevier Sci Ltd, 2009)
This paper deals with multiobjective optimization of laminated cylindrical shells to maximize a weighted sum of the frequency and buckling load under external load. The layer fibre orientation is used as the design variable ...
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 ...
Crustal Thermal Properties of the Central Pontides (Northern Turkey) Deduced from Spectral Analysis of Magnetic Data
(Scientific Technical Research Council Turkey-Tubitak, 2009)
The Pontides can be divided tectonically into three main sectors: Eastern, Central, and Western Pontides. Each of these represents an amalgamated tectonic mosaic consisting of remnants of oceanic, continental, and island ...
Effects of Various Ages of Weaning on Growth Performance of Morkaraman Lambs
(Medwell Online, 2009)
This study was conducted on 46 Redkaraman lambs born at the Ataturk University, Agricultural Faculty Sheep Research Farm. The lambs were weaned at different ages such as 45, 60 and 75 days. After weaning, the lambs were ...
Frequency optimization of laminated skew plates
(Elsevier Sci Ltd, 2009)
In this study, the frequency optimization of laminated skew plates is investigated. The objective function is to maximize the fundamental frequency of the laminated skew plates and the fiber orientation is considered as ...
Thermal buckling load optimization of laminated skew plates
(Elsevier Sci Ltd, 2009)
In this study thermal buckling load optimization of laminated skew plates subjected to uniformly distributed temperature load is investigated. All of the laminates considered are assumed to have fully clamped boundary ...
Implementation of different encoding types on structural optimization based on adaptive genetic algorithm
(Elsevier, 2009)
In this study, the use of new alternatives of encoding types such as quaternary encoding and octal encoding is reviewed along with that of binary and value encodings and how they provide contribution to efficiency and ...
