On the centroid of prime semirings
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2013)
We define and study the extended centroid of a prime semiring. We show that the extended centroid is a semifield and give some properties of the centroid of a right multiplicatively cancellable prime semiring.
Palaeomagnetism of the Cappadocian Volcanic Succession, Central Turkey: Major ignimbrite emplacement during two short (Miocene) episodes and Neogene tectonics of the Anatolian collage
(ELSEVIER SCIENCE BV, 2013)
The Central Anatolian Volcanic Province in Cappadocia includes 13 high volume calc-alkaline ignimbrite sheets emplaced by plinian eruptions within a succession (the Urgup) Formation) after -10 Ma recording the last phase ...
Notes on Jordan (sigma, tau)*-derivations and Jordan triple (sigma, tau)*-derivations
(SPRINGER BASEL AG, 2013)
Let R be a 2-torsion free semiprime *-ring, sigma, tau two epimorphisms of R and f, d : R -> R two additive mappings. In this paper we prove the following results: (i) d is a Jordan (sigma, tau)*-derivation if and only if ...

(SAGE PUBLICATIONS INC, 2013)
Blood vessels are necessary for development and maintenance of the endometriosis and blood flow supplies oxygen and essential nutrient to the disease. Local angiogenesis is regulated by vascular endothelial growth factor ...
Electric field effect on the nonlinear optical absorption in double semi-graded quantum wells
(ELSEVIER SCIENCE BV, 2013)
The electric field dependence of the linear and nonlinear intersubband optical absorption in double semi-graded quantum wells (DSGQWs) is investigated in the effective mass approximation. In our calculations, the position ...
Effect of main process parameters on extraction of pine kernel lipid using supercritical green solvents: Solubility models and lipid profiles
(ELSEVIER SCIENCE BV, 2013)
Supercritical fluid extraction of pine kernel lipids from Pinus pinea L using green solvents (only CO2 or mixed with ethanol) was performed in a laboratory scale extraction system. For the first time in this study the ...
