The phrase "a density constant" is correct and usable in written English.
It can be used in scientific or mathematical contexts where a specific constant related to density is being discussed.
Example: "In this experiment, we will calculate the mass of the substance using a density constant of 2.5 g/cm³."
Alternatives: "a density coefficient" or "a density parameter".
DXR BMD is defined as: c × VPAcomb × (1 − p), where c is a density constant, VPA is volume per area and p is porosity.
DXR-BMD (def: cxVPA combx 1- p), where c is a density constant, VPA is volume per area, and p is porosity) was intended to be the main outcome measure in this study.
The calculation is defined as DXR-BMD = cxVPAx 1-p) where cxVPAx 1-psity constant empirically determined so that DXR-BMD on average is equal to the mid-distal forearm region of the Hologic QDR-2000 densitometer (Hologic, Bedford, MA, USA), VPA is cortical bone volume per area and p is porosity.
In contrast, turbidostats use a feedback control loop to keep cell density constant; in a turbidostat, the cell density is continually monitored and used to compute the dilution rate that achieves a prespecified cell density.
Here Pg depends on temperature, density, and molecular weight, whereas Pr depends on temperature and on the radiation density constant, a = 7.5 × 10−15 ergs per cubic cm per degree to the fourth power.
Given knowledge of a maximum expected interaction density a constant and conservative fraction of the force in equation 3 could be applied over any time-step.
The fit of the Daoud Cotton model (red) is consistent with a constant density of the core, a high constant density region of PEG close to the core, and a decrease of PEG density according to r 4/3 in the outer part of the shell as predicted for star polymers in a good solvent.
A good fit to a constant density region followed by a star-polymer-like, monotonously decaying density profile is shown, which could help explain the unique colloidal properties of such densely grafted core shell nanoparticles.
We illustrate such a modification, with areal density kept constant, in Fig. 4j.
We set a 2σ upper limit of 0.11 on the neutral fraction of the IGM at the redshift of the GRB from the lack of a Lyα red damping wing, assuming a model with a constant neutral density.
The greatest lipid content, 31% of CDW, was obtained using a low-density inoculum, a constant agitation rate of 800 rpm, and an oxygenation rate of 1.5 L/min.
