Thermoluminescence and optically stimulated luminescence properties of natural barytes
(Elsevier Ltd, 2010-12)
Heavy, baryte-loaded, concrete is commonly used as radiation shielding material around high energy particle accelerators. Concrete samples received from a shielding block located at CERN cite contain many crystalline ...
The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(Elsevier Science BV, 2010-02)
The fast component of the optically stimulated luminescence (OSL) signal in quartz is the basic tool for the optical dating. Its relation with the thermoluminescence (TL) glow-peak at about 325 degrees C is well established ...
Investigation of the OSL signal from very deep traps in natural quartz
(Univ Agean, Dept Mediterranean Stud, 2010)
It has been recently reported by several studies that a thermally transferred optically stimulated luminescence (TT-OSL) signal from quartz grains can be used to extend the dating range for quartz samples. The TT-OSL signals ...
Thermally assisted OSL from deep traps in Al2O3:C
(Pergamon-Elsevier Science Ltd, 2010-03)
The present work suggests an alternative experimental method in order to not only measure the signal of the deep traps in Al2O3:C without heating the sample to temperatures greater than 500 degrees C, but also use this ...
Topography of inland deltas: Observations, modeling, and experiments
(Amer Geophysical Union, 2010-04-28)
The topography of inland deltas is influenced by the water-sediment balance in distributary channels and local evaporation and seepage rates. In this letter a reduced complexity model is applied to simulate inland delta ...
Investigation of beachrock using microanalyses and OSL dating: a case study from Bozcaada island, Turkey
(Coastal Education & Research Foundation, 2010-03)
We investigated the origin and absolute age of beachrock samples on Bozcaada Island, located on the northern Aegean Sea coast of Turkey, using energy dispersive X-ray spectroscopy (EDX) and scanning electron microscopy ...
Bilgi yoğun profesyonel hizmet firmalarında bilgi yönetimi: Türkiye'deki reklam ajansları üzerine bir çalışma
(Bilgesel Yayıncılık San Tic Ltd, 2010-12)
Bu çalışma, bilgi yoğun hizmet üreten firmaların performanslarına etki eden bilgi ile ilgili faktörleri ortaya çıkarmayı amaçlamaktadır. Günümüz ekonomisinde firmaların en önemli stratejik gücü olarak değerlendirilen ...
Investigation of OSL signals from very deep traps in unfired and fired quartz samples
(Elsevier Science BV, 2010-03-15)
This paper presents an attempt to isolate experimentally optically stimulated luminescence (OSL) signals which may originate from very deep traps (VDT) in quartz samples. As VDT we consider those traps which are responsible ...
Weakly nonlinear waves in water of variable depth: Variable-coefficient Korteweg-de Vries equation
(Pergamon-Elsevier Science Ltd, 2010-09)
In the present work, utilizing the two-dimensional equations of an incompressible inviscid fluid and the reductive perturbation method, we studied the propagation of weakly non-linear waves in water of variable depth. For ...
Cryptanalysis of Fridrich's chaotic image encryption
(World Scientific Publishing, 2010-05)
We cryptanalyze Fridrich's chaotic image encryption algorithm. We show that the algebraic weaknesses of the algorithm make it vulnerable against chosen-ciphertext attacks. We propose an attack that reveals the secret ...
