Testing a hypothesis for the evolution of sex
(World Scientific Publishing Company, 2000-07-11)
An asexual set of primitive bacteria is simulated with a lit-string Penna model with a Fermi function for survival. A recent hypothesis by Jan, Stauffer, and Moseley on the evolution of sex from asexual cells as a strategy ...
On the contribution of higher order terms to solitary waves in fluid filled elastic tubes
(Birkhauser Verlag, 2000-01)
In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and the approximate equations of an incompressible inviscid fluid, the propagation of weakly nonlinear waves, in ...
Nonlinear waves in a viscous fluid contained in a viscoelastic tube
(Birkhauser Verlag, 2001-11)
In the present work the propagation of weakly nonlinear waves in a prestressed viscoelastic thin tube filled with a viscous fluid is studied. Using the reductive perturbation technique in analyzing the nonlinear equations ...
Amplitude modulation of nonlinear waves in fluid-filled tapered tubes
(Consultants Bureau, 2003-12)
We study the modulation of nonlinear waves in fluid-filled prestressed tapered tubes. For this, we obtain the nonlinear dynamical equations of motion of a prestressed tapered tube filled with an incompressible inviscid ...
The effect of clay particles on film formation from polystyrene latex
(Wiley, 2006-06)
Film formation from surfactant-free polystyrene (PS) latex was performed in the presence of 5% Na-montmorillonite (NaMMT). The composite films were prepared from pyrene (P)-labeled PS particles at room temperature and ...
Vapor-induced film formation from low-T-g particles for different solvent compositions
(Elsevier Inc, 2006-05-15)
The photon transmission method was used to study latex film formation from poly(vinyl acetate) (PVAc) particles induced by two different solvents. Films with the same latex content were prepared from PVAc particles and ...
Cation effect on gel-sol transition of kappa carrageenan
(Springer, 2008-04)
The steady state fluorescence (SSF) technique was employed to study gel - sol transitions of kappa carrageenan in NaCl, KCl and CaCl2 solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. ...
Tunneling rates of single electrons on liquid helium in an extracting field
(Springer/Plenum Publishers, 2009-02)
We calculated the tunneling rates of single electrons from the quasi-stationary states on both liquid He-4 and He-3 in an extracting electric field. The rates were obtained from the widths of the resonance lineshapes of ...
Sorption and slow release kinetics of PAAM gels at various temperatures
(Freund Publishing House Ltd, 2007-11)
Small molecule sorption and slow release in and out of polyacrylamide (PAAm) gels were studied by using steady state fluorescence (SSF) technique. Pyranine (P-y) dissolved in water used as a probe. Fluorescence emission ...
