The phrase "a diminished density of" is correct and usable in written English.
It can be used in contexts discussing a reduction in concentration or amount of something, often in scientific or technical writing.
Example: "The study revealed a diminished density of pollutants in the water after the treatment process."
Alternatives: "a reduced density of" or "a lower density of".
Nevertheless, in the Alps, the main cause of light rings, as well as a main reason for diminished density of wood, is the impact of summer temperature (Gindl, 1999; Gindl et al., 2000).
The stereological count revealed a diminished numerical density of mast cells and a significantly higher volume density of the mononuclear cells.
A diminished numerical density of impaired mast cells and a significantly higher number of mononuclear cells infiltrates in the atherosclerotic plaques of CA vessel wall indicate differential inflammatory processes within the CA vessel wall in diabetic patients vs. hypertensive patients.
Thus, this difference is likely due to the failure of His C mutant embryos to assemble chromatin, resulting in a diminished nucleosome density as shown by the presence of excess MNase hypersensitive DNA.
We observed a continuous decrease in spine density during disease progression, which we could ascribe to a diminished fraction of gained spines.
In Mongolia, however, high stocking densities (particularly due to a high number of goats), a diminished frequency of pasture changes (especially at the spring and winter pastures characterized by low precipitation) and grazing of the summer pasture before flowering of herbaceous plants seem to decrease the herbage offer.
Changes in the total number of spines such as a reduced spine density can therefore result from either a loss of persistent spines, a diminished fraction of new spines or an enhanced fraction of retracted spines.
There was, however, a trend towards decreased proliferation of interstitial cells corroborating with a diminished interstitial cell density in Fn14−/− hearts (Fig. 6a, b).
