Growth Characteristics of Bifidobacteria in Infant Formulas
… similar (P> .05) trends. Results suggest that growth characteristics of bifidobacteria in infant formula were strain specific and that maximum growth occurred in milk-based formula. In another experiment growth promoters, lactulose and fructooligosaccharides (FOS), were inoculated at .5% into …

Finite element models for predicting crack growth characteristics in composite materials
… element models for the prediction of crack growth characteristics, including crack growth direction, in laminated composite materials are presented. Mixed-mode crack growth in isotropic materials, unidirectional and laminated composites is considered. The modified crack closure method is …

HEPATITIS A VIRUS: GROWTH CHARACTERISTICS, PURIFICATION, AND CAPSID GENE ORDER (PEPTIDES, IMMUNOREACTIVITIES, POLYPEPTIDES).
… A virus (HAV) strain HAS-15 was adapted to rapid growth FRhK-4 cells and a one-step growth curve was determined. Detectable virion production was absent for approximately 20 h post-infection (p.i.) and was followed by a 4-day logarithmic phase of virus production. A maximum intracellular virus …

Effects of oxygen on the growth characteristics of carbon nanotubes on conductive substrates
… of oxygen on Fe-catalyzed carbon nanotube (CNT) growth on Ta substrates was studied. CNTs were grown on Fe thin-film catalysts deposited on silicon substrates via exposure to C₂H₄ in a thermal chemical vapor deposition (CVD) furnace. Heating for CVD growth causes the Fe film to dewet to form …

Applications of ecological modeling in managing Central Appalachian upland oak stands for old-growth characteristics
Old-growth forests provide important habitat for wildlife, support the maintenance of biodiversity and serve as control areas for scientific research. Expanding current old-growth stand area by utilizing neighboring younger, managed stands allows private landowners to meet management needs and …

Isolation of a Pseudomonas aeruginosa Aspartate Transcarbamoylase Mutant and the Investigation of Its Growth Characteristics, Pyrimidine Biosynthetic Enzyme Activities, and Virulence Factor Production
The pyrimidine biosynthetic pathway is an essential pathway for most organisms. Previous research on the pyrimidine pathway in Pseudomonas aeruginosa (PAO1) has shown that a block in the third step of the pathway resulted in both a requirement for exogenous pyrimidines and decreased ability to …
