The phrase "a density equal to" is correct and usable in written English.
It can be used when comparing or stating that one density matches another in a scientific or mathematical context.
Example: "The substance has a density equal to that of water, which is approximately 1 gram per cubic centimeter."
Alternatives: "a density that matches" or "a density comparable to".
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].
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.
In detail, at the levels with a square plan the adopted density is 2485 kg/m3 and the Young's modulus is 18,270 MPa, while at the top of the tower where the transversal section changed, it has been adopted a density equal to 2600 kg/m3 and a Young's modulus equal to 3200 MPa.
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.
For each strain, a bacterial suspension with a density equal to 0.5 McFarland (1 × 10 colony-forming units [CFU]/mL) was prepared and properly diluted to obtain a concentration of 1 × 10 CFU/mL; then 10 μL was inoculated in a 96-well microplate containing 100 μL TSB and a serial dilution of the tested substance.
Radiation was measured near soil level on both sides of these plants: plants of the part of the canopy affected by skips received on average the same amount of radiation as a uniform stand with a population density equal to three quarters of the density of the parts of the stand without skips.
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).
An optimum Trimethoprim degradation of 100% was found at pH 3, under a flow rate equal to 1.25 cmin−in− 1, and with a current density equal to 207 mA cm− 2, using a supporting electrolyte concentration equal to 0.49 mol L− 1.
A measurable binding ratio was still obtained for a surface density equal to ρmax/10 (Fig. 9).
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.
The sand used was passing sieve No. 40 and prepared at a relative density equal to 80% to decrease soil saturation period.
