ON COMMUTATIVITY OF SEMIPRIME RINGS WITH GENERALIZED DERIVATIONS
(SCIENTIFIC PUBL-INDIA, 2009)
Let R be an associative ring. An additive mapping f : R -> R is called a generalized derivation if there exists a derivation d : R -> R such that f (xy) f (x)y + xd(y), for all x, y E R. In this paper, we explore the ...
Neotectonic deformation in the western sector of tectonic escape in Anatolia: palaeomagnetic study of the Afyon region, central Turkey
(ELSEVIER SCIENCE BV, 2003)
Following final closure of the Neotethyan Ocean during the late Miocene, deformation in central Turkey has led to crustal thickening and uplift to produce the Anatolian Plateau followed by westward extrusion of terranes ...
Excitonic structure in a quantum well under the tilted magnetic field
(AMER INST PHYSICS, 2000)
By using an appropriate coordinate transform we have calculated variationally the ground state exciton binding energy in the single square well under the tilted magnetic field. The dependence of the binding energy to the ...
Comparative petrogenetic investigation of composite kackar batholith granitoids in Eastern Pontide magmatic arc - Northern turkey
(SPRINGEROPEN, 2004)
The Pontides are an east-west trending orogenic belt which is subdivided into west, middle and eastern sectors according to their different tectonostratigraphy. The Eastern Pontides are represented by west-east-trending ...
Meckel-Gruber syndrome associated with gastrointestinal tractus anomaly
(TURKISH J PEDIATRICS, 2004)
Meckel-Gruber syndrome (MGS) is rare autosomal recessive disorder characterized by occipital encephalocele, postaxial polydactyly and polycystic kidneys. A one day-old girl was admitted to our clinic with occipital ...
Forensic medical evaluation of child sexual abuse cases
(UNIVERSITATSVERLAG ULM GMBH, 2005)
Aims: Aim of this study was to emphasize the interdisciplinary communication and cooperation, and to determine the socio-demographic data of cases referred to the 2. Specialization Board of the State Institute of Forensic ...
Relaxant effects of some benzothiazolinone derivatives on isolated rabbit corpus cavernosum
(SPRINGER-VERLAG, 2001)
In the present study, two 6-(fluorobenzoyl)-3-piperazinomethyl-2benzothiazoline ne derivatives were synthesized and their relaxant effects on isolated rabbit corpus cavernosum investigated. Compounds Y-16 and Y-21 can alter ...
Geometrical effects on shallow donor impurities in quantum wires
(ELSEVIER SCIENCE BV, 2003)
We have studied theoretically the impurity binding energy for wires of different shapes (V-shaped quantum wire (V-QWR) and rectangular wire) with a variational procedure without using any coordinate transformation. The ...
Multicomponent activated sludge model for reactors in series with recycling
(INDERSCIENCE ENTERPRISES LTD, 2005)
Multicomponent models containing both substrate and biomass have an advantage over conventional models in seeking better understanding of activated sludge systems. Such models are also useful in the characterization of ...
Shallow donors in the triple-graded quantum well under the hydrostatic pressure and external fields
(ELSEVIER SCIENCE BV, 2006)
The binding energy of the donor in the triple-graded GaAs-(Ga,Al)As quantum well under the hydrostatic pressure, electric and magnetic fields are calculated by using a variational approach. The results have been obtained ...
