Consider an object of density r and volume V immersed in a fluid (gas or liquid) of density r' ( Figure 4-13 ).
For all ultrasonic variables, a strong association was found with density (r = 0.84 0.90).
ρ is the density, R the gas constant, T the temperature and G0N the plateau modulus.
TN can also become more severe in urban landscapes where there is higher road density (r = 0.307, p < 0.01).
A trend towards a slightly negative correlation was observed between age and density (r = −0.117, P = 0.14).
As a result, its density r is less than that of the surrounding atmosphere and the air parcel is accelerated upward by buoyancy.
Catch-per-unit-effort for the Gulf of Carpentaria was highly correlated with wetland connectivity, the number of estuaries and seagrass patch density (r = 0.57, n = 29).
The tumor/normal tissue (T/N) ratio of 11C-methionine positron emission tomography was found to correlate better with cell density (R = 0.747, p = 0.000042) and Ki-67 index (R = 0.675, p = 0.00041) than with microvessel density (R = 0.467, p = 0.025) in a histological comparison using a stereotactic image.
However, there was a positive correlation between PEN content and trabecular number (r = 0.45, p = 0.001) and connectivity density (r = 0.40, p = 0.004), and a negative correlation between PEN content and trabecular separation (r = −0.29, p = 0.04).
The lengths of all chromosomes were significantly negatively correlated with microsatellite density (r = − 0.456, 0.01 < p < 0.05), and relative abundance and density of SSRs in all chromosomes were significantly negatively correlated with SSR GC content (r = − 0.939/− 0.928, p < 0.01).
There were significant correlations between soil organic carbon and bulk density (r = −0.374**), pH (r = 0.549**), total nitrogen (r = 0.781**), extractable phosphorus (r = −0.109*), exchangeable potassium (r = 0.565**), and cation exchange capacity (r = 0.313**).
