A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
Mineral wool is also known as mineral cotton, mineral fiber, man-made mineral fiber (MMMF), and man-made vitreous fiber (MMVF). Specific mineral wool products are stone wool and slag wool. Europe [who?] also includes glass wool which, together with ceramic fiber, are entirely artificial fibers that can be made into different shapes and are ...

Soil particles can be classified by their chemical composition as well as their size. The particle size distribution of a soil, its texture, determines many of the properties of that soil, in particular hydraulic conductivity and water potential, [1] but the mineralogy of those particles can strongly modify those properties. The mineralogy of ...
In the USDA soil taxonomy, sapric may be a subtype of a haplohemist or glacistel type, and may also be a diagnostic organic soil material where the fiber content is less than one-sixth of the volume. [2]
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup , especially antigorite , lizardite , and chrysotile or white asbestos, all of which are commonly found in ultramafic ...
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
