Soliton propagation in a medium with Kerr nonlinearity and resonant impurities: A variational approach
(2003-04-01)
The soliton propagation in a medium with Kerr nonlinearity and resonant impurities was studied by a variational approach. The existence of a solitary wave was shown within the framework of a combined nonintegrable system ...
A mathematical model for wave propagation in elastic tubes with inhomogeneities: Application to blood waves propagation
(Elsevier B.V., 2007-12-15)
We study the propagation of waves in an elastic tube filled with an inviscid fluid. We consider the case of inhomogeneity whose mechanical and geometrical properties vary in space. We deduce a system of equations of the ...
Managing uncertainty propagation in innovation ecosystems
(2021-10-01)
The propagation of uncertainty occurs when information, perceived as revealing uncertainty, spreads through the innovation ecosystem. This paper explores how entrepreneurs cope with uncertainty propagation. Drawing on four ...
Effect of juvenility on cutting propagation of red pitaya
(Cambridge University Press, 2008-09-01)
Introduction. Pitaya (Hylocereus undatus) is an exotic fruit species little known in Brazil and which needs basic studies about plant nutrition, propagation and physiology. Emphasizing the co-existence of juvenile and adult ...
Morphological aspects of the propagation in Heliconia velloziana L. Emygd. (Zingiberales: Heliconiaceae)
(Brazilian Archives of Biology and Technology, 2003-01-01)
A morfologia da propagação por sementes e da propagação vegetativa foi estudada em Heliconia velloziana L. Emygd. (Heliconiaceae). As sementes levaram cerca de quatro meses para germinar, provavelmente pelo embrião ...
