Interactions of nonlinear waves in fluid-filled elastic tubes
(Verlag Z Naturforsch, 2007-02)
In this work, treating an artery as a prestressed thin-walled elastic tube and the blood as an inviscid fluid, the interactions of two nonlinear waves propagating in opposite directions are studied in the longwave approximation ...
Swelling activation energy of kappa-carrageenan in its gel state: A fluorescence study
(John Wiley & Sons Inc, 2007-12-15)
A steady-state fluorescence technique was employed to study the swelling Of K-carrageenan gels at various temperatures. Pyranine was used as a fluorescence probe. The fluorescence intensity of pyranine was measured during ...
Electrochromic switching of WO3 nanostructures and thin films
(Springer-Verlag, 2006-04)
We present transmission measurements through tungsten tri-oxide nanostructures and thin films prepared by sol-gel process on micro-contact printed substrates. Identical electrochromic switching times are found for both the ...
The modified reductive perturbation method as applied to the Boussinesq equation
(Verlag Z Naturforsch, 2007-08)
In this work, we extended the application of "the modified reductive perturbation method" to long water waves and obtained the governing equations of Korteweg-de Vries (KdV) hierarchy. Seeking localized travelling wave ...
Interactions of nonlinear ion-acoustic waves in a collisionless plasma
(Elsevier Science BV, 2007-09-15)
In the present work, based on a one-dimensional model, the interaction of two solitary waves propagating in opposite directions in a collisionless plasma is investigated by use of the extended Poincare-Lighthill-Kuo (PLK) ...
Strategies for the evolution of sex
(American Physical Soc, One Physics Ellipse, 2001-12)
We find that the hypothesis made by Jan, Stauffer, and Moseley [Theory Biosci. 119, 166 (2000)] for the evolution of sex, namely, a strategy devised to escape extinction due to too many deleterious mutations, is sufficient ...
An essential approach to the architecture of diatomic molecules: 1.Basic theory
(Optical Soc Amer, 2004-11)
We consider the quantum-mechanical description of a diatomic molecule of electronic mass m(0e), internuclear distance R-0, and total electronic energy E-0e. We apply to it the Born-Oppenheimer approximation, together with ...
A method for higher-order expansion in non-linear ion-acoustic waves
(Pergamon-Elsevier Science, 2000-03)
The basic equations describing the non-linear ion-acoustic waves in a cold collisionless plasma, in the longwave limit, is re-examined through the use of a modified multiple-scale expansion method. Expanding the field ...
Calculation of the T-X phase diagram for a mixture of liquid crystals
(Pergamon-Elsevier Science, 2000-12)
In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. ...
A travelling wave solution to the KdV-Burgers equation
(Elsevier Inc, 2004-07-15)
In the present work, by introducing a new potential function and by using the hyperbolic tangent method and an exponential rational function approach, a travelling wave solution to the KdV-Burgers (KdVB) equation is ...
