They have weight-age in determining the renal calculi formation because urinary stone is made up of organic material, mainly collagen, and inorganic materials like calcium oxalates, hydroxyapatite and other phosphates.
Using the data, it is possible to compare with the conventional electro-ceramics and other such bio-materials, their polar nature, hence their ability to store charges and their dielectric loss.

It can be concluded that, plasma can be a useful method for improving the sorption active materials properties.
In order to impart the required functional properties to the fiber or fabric, it is customary to subject the material to different types of physical and chemical treatments.
It is concluded that, by plasma treatment it is easy to improve the properties of sorption materials for using in wastewater purification.

Irregular evolution of friction coefficient, recorded during the ball-on-disc test on Si3N4 based ceramic materials, was analysed by means of fractal geometry methods.
Investigation of friction coefficient is of peculiar importance with respect to the possible use of particular materials for disc brakes in automotive applications.
During each wear test period, the evolution of friction coefficient is similar practically for all materials.
This is in accordance with our working hypothesis that, at least for brittle materials, the friction coefficient fluctuations reflect the fluctuations in the stress-strain state of the subsurface material during the wear damage and fractal fragmentation.
