Higher ultrasonic frequency, wider bandwidth, and finer step size increase spatial resolution, but decrease penetration depth and imaging speed, and vice versa.
On the other hand, reductions in air infiltration should decrease penetration of outdoor pollutants, which is of particular importance in traditionally leakier low-income households (Chan et al. 2005) in neighborhoods with high outdoor air pollution.
The addition of nutrients (through the discharge of untreated sewage or the seepage of soluble mineral fertilizers, for example) to coastal waters results in increased phytoplankton growth, high levels of dissolved and particulate organic materials, decreased penetration of light through seawater, and alteration of the community structure of bottom-dwelling organisms.
Actually, assessments of the clinical behaviour of crosslinked UHMWPE depend on radiographic measurement analyses: these demonstrate an initial penetration of the femoral head into the crosslinked insert, followed by a decreased penetration after the first year compared to conventional inserts.
This has previously also been observed with EGFR-targeting 15-kDa nanobodies in larger A431 xenografts and was suggested to be due to necrosis and/or decreasing penetration of the probe [35].
In addition, the decreased penetration of UV light irradiation in a high TiO2 loading attributable to light scattering and screening could result in the reduction of TiO2 specific activity [37].
The result of decreased penetration, increased softening point, elastic recovery, viscosity and complex modulus indicates that WTR/APAO compound modification improves the high temperature performance and rutting resistance of asphalt binders.
The results showed the introduction of thermochromic powders could improve high-temperature stability of asphalt by increasing its softening point, viscosity, complex modulus while decreasing penetration and phase angle.
After mixed with WTR and RPE, the asphalts show decreased penetration and phase angle, increased softening point, rotational viscosity and complex modulus, indicating that intermediate and high temperature rheological properties of the asphalts have been improved by the modification of WTR and RPE.
Similar findings for decreased penetration defense and more frequent entry of pathogens into epidermal cells, were also reported for Arabidopsis pen-mutants (for review see [ 41]).
Especially for amisulpride, a decreased penetration of the blood brain barrier would explain the marked tendency of this medicine to cause a rise in PRL values [ 195, 421].
