Soliton propagation in a medium with Kerr nonlinearity and resonant impurities: A variational approach
(2003-01-01)
Using a variational approach we have studied the shape preserving coherent propagation of light pulses in a resonant dispersive medium in the presence of the Kerr nonlinearity. Within the framework of a combined nonintegrable ...
Evaluation of the radiopacity of calcium hydroxide- and glass-ionomer-based root canal sealers
(Blackwell Publishing, 2008-01-01)
Aim To evaluate the radiopacity of calcium hydroxide-based root canal sealers (Acroseal, Sealapex and Sealer 26), a glass-ionomer-based sealer (Activ GP Sealer) and a zinc oxide and eugenol-based sealer (Intrafill).Methodology ...
A review on the formation of heteronuclear cold molecules
(M A I K Nauka - InterperiodicaMoscow, 2008-11)
Is the characterization of biological systems as complex systems in the mathematical sense a fruitful assertion? In this paper we argue in the affirmative, although obviously we do not attempt to confront all the issues ...
Asymmetry of characteristic X-ray peaks obtained by a Si(Li) detector
(Pergamon-Elsevier Science Ltd, 2007-05)
The asymmetry of the characteristic X-ray peaks obtained using a Si(Li) detector is mainly due to incomplete charge collection. Impurities and defects in the crystalline structure of Si can act as "traps" for holes and ...
Electrochemical synthesis of Rh-Pd bimetallic nanoparticles onto a glassy carbon surface
(Elsevier Science Sa, 2016-10)
Rh-Pd bimetallic nanoparticles were prepared successfully by sequential electrodeposition on a glassy carbon (GC) substrate using single potentiostatic pulses. The generated particles were characterized by ex-situ atomic ...
