This ratio is represented by the Elsasser number, Λ, which can be approximated by assuming a characteristic current density, magnetic induction, density, rotation rate, and velocity scale: Lambda = frac{text{Lorentz}}{text{Coriolis}} = frac{left|frac{1}{rho_{o}} mathbf{J} times textbf{B}right|}{|2 boldsymbol{Omega} times mathbf{u}|} approx frac{JB}{2 rho_{o} Omega U}.

Using precultures with an OD600 nm between 0.1 and 0.2, the expression would reach induction density (OD600nm 5–7) within 5 h and reach an overnight OD600 of approximately 10 13.
Three weeks after single lesion induction, the density of Olig2/BrdU double-positive cells was significantly increased in previously demyelinated cortex as compared to the non-demyelinated control group (Suppl. Fig. 2).
Three days after the first lesion induction, the density of Olig2+ cells was not reduced in demyelinated cortex (45.8 ± 2.9 cells/mm) and similar to non-lesioned controls (45.7 ± 2.5 cells/mm, Fig. 8b).
At 3 days after the split (and CuSO4 induction; cell density ∼1 × 10), half of the induced flasks (10 flasks) were mock treated with sterile water, whereas another 10 (induced) flasks were treated with 10 μg/mL LPS for a period of 3 hr.
We investigated effects of host strain, plasmid, inducer concentration, pre-induction temperature and cell density at induction with design of experiment (DOE).
In this study, samples from evaluations of media, growth temperature, culture density, induction conditions, and other variables were processed successively.
Induction of trichome density in response to insect infestation and/or elicitor application will have a substantial effect in controlling insect herbivory.
Densitometry data were plotted as the fold induction of relative density units, with the zero value absorbance in each figure set arbitrarily to 1 or 100%.
Three weeks after the first lesion induction, however, the density of Olig2+ cells was significantly increased in rMOG-immunized rats (60.1 ± 6.2 cells/mm) compared to untreated controls (p < 0.01), to rMOG-immunized rats on day 3 (p < 0.01) and to cytokine-injected controls (40.8 ± 1.0 cells/mm; p < 0.01).
Seventeen experiments were designed and conducted for investigation of cell density to start induction, induction temperature, and induction time.
