Transient director patterns upon flow start-up of nematic liquid crystals (an explanation for stress oscillation damping)
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2001-07)
In this work we attempt to determine the origin of damped stress oscillations upon flow start-up of a nematic liquid crystalline monodomain. These damped stress oscillations were first observed by Gu et al. (1993) in the ...
Interplay between perturbative and non-perturbative effects in the stealthy Higgs model
(Springer-Verlag; Springer-Verlag Berlin Heidelberg / Società Italiana di Fisica, 2001-05)
We study corrections to electroweak precision variables in a model with strongly interacting singlet Higgs particles.
Alteration of the growth rate and lag time of Leuconostoc mesenteroides NRRL-B523
(John Wiley & Sons, Inc., 2001-03-20)
Bacterial profile modification is an important enhanced oil recovery technique used to direct injected water into a reservoir's low permeability zone containing trapped crude oil. During water flooding, the use of bacteria ...
Validation of flow cytometric competitive binding protocols and characterization of fluorescently labeled ligands
(John Wiley & Sons, Inc., 2001-10-01)
Background Fluorescently labeled ligands and flow cytometric methods allow quantification of receptor-ligand binding. Such methods require calibration of the fluorescence of bound ligands. Moreover, binding of unlabeled ...
Computational analysis of surface-tension-driven coating-defect flow
(Wiley Subscription Services, Inc., A Wiley Company, 2001-04)
Bondline readout (BLRO) is a coating defect frequently exhibited on adhesively-bonded, polymeric automotive body panels painted with high-glamor/flow clearcoats. BLRO or telegraphing results from Marangoni-type, ...
Fe-ZSM-5 for Selective Catalytic Reduction of NO with NH3: A Comparative Study of Different Preparation Techniques
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2001-07)
Fe-ZSM-5 are prepared by using four different techniques: conventional aqueous ion-exchange (CA), improved aqueous ion-exchange (IA), solid-state ion-exchange (SS) and chemical vapor ion-exchange (CV). All of the catalysts ...
Predicting the linear viscoelastic properties of monodisperse and polydisperse polystyrenes and polyethylenes
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2001-11)
For linear homopolymers the linear viscoelastic predictions of the double reptation model are compared to those of a recent, more detailed model, the “dual constraint model” and to experimental data for monodisperse, ...
Morphological evolution of thick wax deposits during aging
(Wiley Subscription Services, Inc., A Wiley Company, 2001-01)
The presence of waxes in crude oil can lead to the formation of wax deposits on the walls of cold subsea pipelines, which restricts flow and can lead to plugging of the pipelines. This problem has recently become more ...
Existence of a critical carbon number in the aging of a wax-oil gel
(Wiley Subscription Services, Inc., A Wiley Company, 2001-09)
A fundamental study was carried out to understand the aging (or hardening) of the wax-oil gels formed in the subsea pipelines during the flow of crude oil from offshore wells to shore. The aging process is a counterdiffusion ...
Biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2001-02-05)
Exopolymer-producing bacteria can be used to modify soil profiles for enhanced oil recovery or bioremediation. Understanding the mechanisms associated with biomass plug development and propagation is needed for successful ...
