In addition, the effects of four major factors (contact pressure, micro-hardness, root-mean-squared (RMS) surface roughness, and mean absolute surface slope) on thermal contact resistance were investigated.
AHP admits the hardness for rooting out all faults before product release, and autonomously patches problems of application programs.
The surface hardness for the root caries lesions was graded and recorded with a standardized dental probe.
The application of a high-fluoride containing dentifrice (5000 ppm F) in adults, twice daily, significantly improves the surface hardness of untreated root caries lesions when compared with the use of regular fluoride containing (1350 ppm F) toothpastes.
The results of this study do however suggest that the surface hardness of the root caries lesions improved in both groups (control and test), that is, both toothpastes improved the mean hardness scores of the lesions, in a time frame of 6 month usage.
The application of a high-fluoride containing dentifrice (5000 ppm F) in adults, twice daily, significantly improves the surface hardness of otherwise untreated root caries lesions when compared with the use of regular fluoride containing (1350 ppm F) toothpastes.
It may be possible to improve the compressive strength and hardness of the bio-roots by selecting optimal bioengineered materials and by optimizing the implanted stem cell numbers and quality.
You are not hard for hardness's sake.
Surface (0 – 6 inches) and subsurface (6 – 18 inches) hardness (indicating compaction that limits root growth, water transmission and plant access to nutrients and water) scored mostly low and medium throughout the site.
Jewellers' favourite allotrope of carbon, diamond, also gets its name from the same etymological root owing to its hardness.
For example, drought induces mechanical stress on roots due to soil hardness [ 9], osmotic stress because of cell dehydration and removal of water to the extra-cellular space [ 10], and oxidative stress by the accumulation of reactive oxygen species (ROS) [ 11].
