The electric field dependence of a donor impurity in graded GaAs quantum wires
(SPRINGER HEIDELBERG, 2004)
The effect of the electric field on the binding energy of the ground state of a shallow donor impurity in a graded GaAs quantum-well wire (GQWW) was investigated. The electric field was applied parallel to the symmetry ...
Shear flocculation of celestite with sodium oleate and tallow amine acetate: effects of cations
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)
Sodium oleate and tallow amine acetate (TAA) were used as surfactants for the shear flocculation of celestite. The shear-flocculation power values obtained with sodium oleate were higher than those obtained with TAA in ...
A comparison of the effects of rapid maxillary expansion and fan-type rapid maxillary expansion on dentofacial structures
(E H ANGLE EDUCATION RESEARCH FOUNDATION, INC, 2004)
The aim of this study was to evaluate and compare the sagittal, transverse, and vertical effects of rapid maxillary expansion (RME) and fan-type RME on dentofacial structures. The study group consisted of 34 patients, 14 ...
A synthesis: Late Cenozoic stress field distribution at northeastern corner of the Eastern Mediterranean, SE Turkey
(EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2004)
Fault kinematic analysis and inversion of focal mechanisms of shallow earthquakes reveal significant evolution of the regional stress regime in the northeastern most corner of the Eastern Mediterranean region since the ...
Mesanenin inflamatuar psödotümörü: Bir olgu sunumu
(2004)
Mesaneyi tutan inflamatuar psödotümörler hem klinik hem de histolojik olarak malign tümörleri andırır. Bu lezyonlar, inflamatuar psödotümöre ek olarak psödosarkomatöz miyofibroblastik proliferasyon, psödomalign iğsi hücreli ...
Antimicrobial and antioxidative activities of the essential oils and methanol extracts of Salvia cryptantha (Montbret et Aucher ex Benth.) and Salvia multicaulis (Vahl)
(ELSEVIER SCI LTD, 2004)
The essential oils and methatiolic extracts of Salvia cryptantha and Salvia multicaulis were examined for their potential antimicrobial and radical scavenging activities. No, or slight, activity was observed when the polar ...
Intersubband transitions of Si delta-doped GaAs layer for different donor distribution models
(IOP PUBLISHING LTD, 2004)
For different donor distribution types we theoretically investigate the intersubband transitions of single Si delta-doped GaAs structure as dependent on the applied electric held. The diffusion of donor impurities is taken ...
Öğrencilerin Matematiğe Yönelik İçsel ve Dışsal Motivasyonlarının Belirlenmesi
(2004)
Motivasyon, birçok alanda özellikle de eğitimde çok etkili bir faktördür. Motivasyon, öğrencilerin matematik gibi anlamakta zorlandıkları derslerde özellikle ihmal edilmemesi gereken bir boyuttur. Motivasyonun içsel ve ...
New mineralogic data and implications for the tectonometamorphic evolution of the Alanya nappes, Central Tauride Belt, Turkey
(TAYLOR & FRANCIS INC, 2004)
The Alanya Unit, consisting of three nappes, crops out in the Demirtas-Anamur area of the Tauride Belt and is related to the Alpine orogeny. The Mahmutlar nappe of Permian and pre-Permian age progressively evolved as ...
Block vertebra, hemisacralization and sacral agenesis observed in an adult male skeleton - A case report
(MAN INDIA PUB, 2004)
The complete or partial union of two or more vertebrae is called block vertebra and the conversion of the 5(th) lumbar vertebra into a sacral vertebra character sacralization. The block vertebrae are mostly observed in the ...
