The panel machine, which was supplied by the swiss company Bell, is the heart of the production facility. Three cylindrical sieves rotate in the cement-fiber-water slurry. The rotation leads to the formation of a ca. 0.9-millimeter-thin layer, which is wound around the format roll as often...
We also look at asbestos fibers in our forensic microscopy lab, but we're addressing on-site visual inspection for asbestos here, not polarized-light microscopy such as our lab photo ofcrocidolite. Curved asbestos fibers chrysotile. Straight asbestos fibers are amphiboles. The five amphiboles incl...

Artwork: The fibers in HEPA filters (shown here as gray bars) trap dust and dirt particles in three ways. Some particles crash into filter fibers and are absorbed by impact. Some are caught as they flow along in the moving airstream, move too close to a fiber and are trapped by ...
Industrial health studies have shown that, unlike some asbestos fibers, carbon fibers are too large to be a health hazard when inhaled. They can be an irritant, however, and people working in the area should wear protective masks. The carbon fibers can also cause skin irritation, especially ...
Asbestos fibers can be breathed into the lungs and can cause serious health problems, including lung cancer. For this reason, any major repairs and removal must be done by asbestos professionals. Any material suspected of containing asbestos should be wetted before handling. Any asbestos waste shoul...
from yarn by the fact that thread is used to sew together garments or other products, but yarn is the collection of fibers used to weave or knit into a textile fabric. The terms are confusing and are often used interchangeably; thread can be made of yarn, but yarn is not made of ...
1. Thin drums are dangerous drums. If not replaced, the drum can wear to the point where it may literally disintegrate. And if the drum fails, so do the brakes! 2. Reduced braking efficiency. The increased inside diameter of a badly worn drum won't match up with a new set of linings...
Diamond thin films have been proposed in vivo, as coatings for implants and prostheses [180]. The increasing interest and the recent development of new techniques for constructing micro/nanodevices [[181], [182], [183], [184], [185]] has rapidly broadened the number of diamond-based MEAs ...
"We believe that the most dangerous types of fibers—ones that are particularly thin and long—likely cause immune cells called macrophages to recruit other immune cells to asbestos exposure sites within tissue. This response prevents the immune cells from reaching other places where they're needed...
