Effects of curing time and filler concentration on curing and postcuring of urethane dimethacrylate composites: A microcalorimetric study
(John Wiley & Sons, Inc., 1998-05)
The isothermal enthalpy changes with time of a dental composite were examined by microcalorimetry to isolate the effects of different filler concentrations and curing times on chemical aging of these composites. Urethane ...
Liquid-crystalline phase transition in organophosphazenes
(John Wiley & Sons, Ltd., 1998-10)
Organophosphazenes with a similar mesogenic moiety were prepared and their mesogenicity was studied by differential scanning calorinetry (DSC) measurements and polarizing microsope observations. In cyclotriphosphazenes ...
Rapid detection of human infections with fluorine-18 fluorodeoxyglucose and positron emission tomography: preliminary results
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
The purpose of this study was to evaluate the feasibility of 2-[fluorine-18]fluoro-2-deoxy- d -glucose (FDG) and positron emission tomography (PET) for rapid detection of human infections. Eleven patients who were known ...
Optimizing seeding and culture methods to engineer smooth muscle tissue on biodegradable polymer matrices
(Wiley Subscription Services, Inc., A Wiley Company, 1998-01-05)
The engineering of functional smooth muscle (SM) tissue is critical if one hopes to successfully replace the large number of tissues containing an SM component with engineered equivalents. This study reports on the effects ...
Genetic structure of five susceptibility gene regions for coronary artery disease: disequilibria within and among regions
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
We analyzed two-locus disequilibria for 16 polymorphic loci of seven susceptibility genes for coronary artery disease located in five chromosomal regions distributed across four chromosomes. Included were the genes coding ...
Pt/MCM-41 catalyst for selective catalytic reduction of nitric oxide with hydrocarbons in the presence of excess oxygen
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 1998-03)
First results are reported on the use of MCM-41 mesoporous molecular sieve as the support for Pt for the selective catalytic reduction of NO by hydrocarbons in the presence of O 2 . MCM-41 provided the highest specific NO ...
Regulation of fucosyltransferase-VII expression in peripheral lymph node high endothelial venules
(WILEY-VCH Verlag GmbH, 1998-10)
Binding of L-selectin to the highly glycosylated peripheral lymph node addressins (PNAd) plays a central role in the normal recirculation of lymphocytes between the bloodstream and the lymph node. This interaction requires ...
Atomistic Simulation of Curvature Driven Grain Boundary Migration
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-02)
We present two dimensional molecular dynamics simulations of grain boundary migration using the half-loop bicrystal geometry in the experiments of Shvindlerman et al. We examine the dependence of steady-state grain boundary ...
Remembering John G. Wagner
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1998-06)
Polyhedral oligomeric silsesquioxane(POSS)-based polymers
(John Wiley & Sons, Ltd., 1998-10)
A diverse and entirely new class of monomer and polymer technology based on polyhedral oligomeric silsesquioxane (POSS) reagents has been developed. POSS reagents are unique in that they are physically large (approx. 15 14° ...
