The phrase "a density equal to or" is correct and usable in written English.
It can be used in scientific or mathematical contexts when discussing measurements or comparisons of density.
Example: "The material must have a density equal to or greater than the specified threshold to ensure structural integrity."
Alternatives: "a density that is at least" or "a density of no less than".
Right-upper: spectra of electrons escaping the NP, as compared to the case when the NP is replaced by normal water or water with a density equal to gold.
The fluid was air with a density equal to 1.225 [kg/m3] and a dynamic viscosity equal to 1.7894 10−5 [Pa s].
To obtain cell culture doubling times (DT), cells were plated at a density equal to that used in dose-response experiments and allowed to grow in culture for 96 h.
As a UMA was defined as the association of fever with a parasite density equal to or higher than 2500/µl, we selected the same threshold to discriminate between two AC groups.
Our model is able to reproduce the phenomenon: a comparison between the two different density profiles from one run of a simulation with an overall density equal to 2.5m-2 ishownwn in Figure 12 (a).
A measurable binding ratio was still obtained for a surface density equal to ρmax/10 (Fig. 9).
The sand used was passing sieve No. 40 and prepared at a relative density equal to 80% to decrease soil saturation period.
For L. acidophilus, an optical density equal to 1 corresponds to 108 cells/ml.
For the experiments, bacterial strains were inoculated onto blood agar plates, incubated for 18 hours at 35°C, dissolved in PBS to an optical density equal to McFarland No. 0.5 and then diluted 1 10 (to approximate concentration 10 cells/ml).
For the experiments, S. aureus ATCC 6538 was inoculated onto blood agar plates, incubated for 18 hours at 35°C, and then diluted in PBS to an optical density equal to McFarland No. 0.5.
The smallest μFC has a reaction surface of 0.11 cm2 and has an output power density equal to 22.9 mW cm−2.
