Externally Applied Cyclic Strain Regulates Localization of Focal Contact Components in Cultured Smooth Muscle Cells
(Kluwer Academic Publishers-Plenum Publishers; Biomedical Engineering Society ; Springer Science+Business Media, 2002-07)
Mechanical signals are critical regulators of cellular gene expression, yet little is understood of the mechanism whereby cells sense mechanical forces. In this study we have tested the hypothesis that mechanical strain ...
Low-temperature SCR of NO with NH 3 over noble metal promoted Fe-ZSM-5 catalysts
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2005-04)
We have reported previously the excellent performance of Fe-exchanged ZSM-5 for selective catalytic reduction (SCR) of NO with ammonia at high temperatures (300–400 °C). In this work, we found that the reaction temperature ...
Fischer-tropsch synthesis on charcoal-supported molybdenum: The effect of preparation conditions and potassium promotion on activity and selectivity
(Elsevier, 1985)
High dispersion and high activity charcoal-supported molybdenum catalysts were prepared using incipient wetness and equilibrium adsorption methods. Activities and selectivities of these catalysts were tested after reducing ...
Report on the catalytic activity of 6-heteropolymolybdates as potential Fischer-Tropsch synthesis catalysts
(Elsevier, 1986-02-14)
Unsupported and supported decomposition products of 6-heteropolymolybdates were tested as possible Fischer-Tropsch synthesis catalysts. Depending on the heteroatom, the activity changes significantly and the best supported ...
Computer modeling of antibiotic fermentation with on-line product removal
(Wiley Subscription Services, Inc., A Wiley Company, 1988-07-20)
The fermentation of Streptomyces griseus for the production of cycloheximide is similar to other antibiotic fermentations in that product synthesis is subject to feedback regulation and the desired product is degraded ...
Feedback regulation and the intracellular protein profile of Streptomyces griseus in a cycloheximide fermentation
(Springer-Verlag, 1990-11)
Two-dimensional gel electrophoresis (2-D PAGE) was used to study the intracellular protein profile of Streptomyces griseus in relation to cycloheximide (CH) biosynthesis. Four proteins (CR1-CR4) were found to be significantly ...
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 ...
CO hydrogenation on Ru/Al2O3: Selectivity under transient conditions
(Elsevier, 1987-06)
Transient response and isotopic tracer techniques were used to investigate the surface coverages of the reactants and the selectivity of ruthenium/alumina catalysts in CO hydrogenation. Two forms of carbon--active carbidic ...
Formation of polyol–fatty acid esters by lipases in reverse micellar media
(Wiley Subscription Services, Inc., A Wiley Company, 1992-06-05)
The synthesis of polyol–fatty acid esters has strong implications in such industries as foods, cosmetics, and polymers. We have investigated these esterification reactions employing the polyols ethylene glycol, 2-monoglyceride, ...
Application of membrane-based preferential transport to whole broth processing
(Wiley Subscription Services, Inc., A Wiley Company, 1997-08-20)
Preferential transport in adsorptive membranes can be used to selectively remove biochemicals directly from fermentation broths. During preferential transport, an adsorbing solute is selectively transported across the ...
