The effects of exopolymers on cell morphology and culturability of Leuconostoc mesenteroides during starvation
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-11)
Biofilm formation by bacterial cells can be used to modify the subsurface permeability for the purpose of microbial enhanced oil recovery, bio-barrier formation, and in situ bioremediation. Once injected into the subsurface, ...
Poly(organophosphazene)s and the sol–gel technique
(John Wiley & Sons, Ltd., 1999-05)
We report a survey of the utilization of phosphazene materials in combination with metal alkoxide precursors to form ceramics through the sol–gel technique. Silicon, titanium, zirconium and aluminum three-dimensional oxide ...
Triple Junction Mobility: A Molecular Dynamics Study
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
We present a molecular dynamics simulation study of the migration of individual grain boundary triple junctions. The simulation cell was designed to achieve steady state migration. Observations of the triple junction angle ...
Polyhedral liquid crystal silsesquioxanes
(John Wiley & Sons, Ltd., 1999-04)
Synthetic routes towards monodisperse polyhedral liquid-crystalline silsesquioxanes are described. The liquid-crystalline phase behaviour of these structurally uniform materials, with various silsesquioxane core and mesogenic ...
Glucocorticoid-reinforced responding in the rhesus monkey
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-11)
Rationale: Glucocorticoids have been reported to have rewarding effects in rats and may lead to drug-seeking behavior in humans under some circumstances. Objectives: The present study investigated whether glucocorticoids ...
Cyclic siloxanes and silsesquioxanes as cores and frameworks for the construction of ferrocenyl dendrimers and polymers
(John Wiley & Sons, Ltd., 1999-04)
Starting from 1,3,5,7-tetramethylcyclotetrasiloxane as core, novel ferrocenyl silicon-containing dendrimers have been constructed up to the third generation, which contains 16 peripheral ferrocene moieties. As precursors ...
Age-related difference in cardiac adaptation to chronic hypertension in rats, with and without nifedipine treatement
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-08)
Three myosin isozymes, V1 (αα MHC = Myosin Heavy Chain gene), V2 (αβ MHC) and V3 (ββ MHC) that are identified in the cardiac ventricles of most mammals have been shown to shift to a V3 predominance pattern during cardiac ...
A pH- and ionic strength-responsive polypeptide hydrogel: Synthesis, characterization, and preliminary protein release studies
(John Wiley & Sons, Inc., 1999-12-15)
A novel polypeptide hydrogel has been synthesized by crosslinking poly(L-glutamic acid) (PLG) with poly(ethylene glycol) (PEG). The PLG-PEG hydrogel was shown to be highly hydrophilic, and the extent of swelling varied ...
MR-Bildgebung der NierenNeue Ansätze in der Diagnostik*
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-05)
Fragestellung: Darstellung neuer diagnostischer Möglichkeiten im Bereich der Niere mittels schneller Magnetresonanz (MR)- Bildgebung. Methodik: Vorgestellt wird ein kombiniertes morphologisches und funktionelles ...
