The internet and democratic local governance: the context of Britain
(Elsevier Science, 2005-06)
This article seeks to explore the role of the Internet in enhancing democratic local governance. The article suggests that the unique role of elected local authorities is under threat both because of declining levels of ...
Films formed from polystyrene latex/clay composites: A fluorescence study
(Springer New York, 2005-07)
This study reports a steady-state fluorescence (SSF) technique for studying film formation from surractant-free polystyrene (PS) latex and Na-montmorillonite (SNaM) composites. The composite films were prepared from pyrene ...
Eshelby tensors for a spherical inclusion in microelongated elastic fields
(Pergamon-Elsevier Science ltd, 2005-01)
Eshelby tensors are found for a spherical inclusion in a microelongated elastic field. Here. a special micromorphic model is introduced to describe the damaged material which defines the damage as the formation and the ...
Time evolution of film formation from polystyrene particles: a percolation approach
(Springer, 2005-12)
This work reports the film formation process from surfactant-free polystyrene (PS) latex particles. Steady state fluorescence and photon transmission techniques were used to study the evolution of film formation. The films ...
Molecular alignment during gel formation from methyl methacrylate: An excimer fluorescence study
(Taylor & Francis Ltd, 2005-05)
Glass transition during bulk polymerization was studied in free-radical cross-linking copolymerization (FCC) of methyl methacrylate (MMA) using the steady-state fluorescence (SSF) technique. Naphthalene (N) was used as a ...
Weakly non-linear waves in a tapered elastic tube filled with an inviscid fluid
(Pergamon-Elsevier Science Ltd, 2005-07)
In the present work, treating the artery as a tapered, thin walled, long and circularly conical prestressed elastic tube and using the longwave approximation, we have studied the propagation of weakly non-linear waves in ...
Small molecule desorption prior to dissolution of a polymeric glass
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07-15)
Poly(methyl methacrylate) (PMMA) discs in various molecular weights (M-w) were prepared by free-radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state ...
Two remarks on a generalized Davey-Stewartson system
(Elsevier Ltd, 2006-03-01)
We present two results on a generalized Davey-Stewartson system, both following from the pseudo-conformal invariance of its solutions. In the hyperbolic-elliptic-elliptic case, under some conditions on the physical parameters, ...
Quarantine region scheme to mitigate spam attacks in wireless sensor networks
(IEEE, 2006-08)
The Quarantine Region Scheme (QRS) is introduced to defend against spam attacks in wireless sensor networks where malicious antinodes frequently generate dummy spam messages to be relayed toward the sink. The aim of the ...
The sectoral sweeper scheme for wireless sensor networks: Adaptive antenna array based sensor node management and location estimation
(Kluwer Academic Publishers-Plenum Publishers, 2006-12)
We introduce a novel sensor node management and location estimation method referred as sectoral sweeper (SS) scheme that uses an adaptive antenna array (AAA) at a central node in wireless sensor networks (WSNs). With the ...
