Despite its defined clinical and neuropathological criteria, the aetiology and pathogenesis of the disease remain unclear. It is considered to be a degeneration of the nervous system whose causes and mechanism are still unclear. Much of what isRead more
The bounds of community standards have been stretched by mainstreamingmovies, opening the way even further for the legalization of more explicit fare (Jenish53). There may thus be a theoretical reason to conceive of pornography more broadly than simply sexuallyRead more
Self Healing Plastics
approach is for the capsules to release an adhesive that simply fills the crack and binds the material together. Materials like this have been tested by firing bullets (up to 9mm in diameter) at them. In a slightly different approach, the main body of the material is a solid polymer, while the capsules contain a liquid monomer (one of the basic, endlessly repeated units that makes up the polymer).
Materials scientists have been trying to design self-healing materials that work the same way. The tubes lead into pressurized reservoirs (think of syringes that are already pushed in slightly). Although you might think fiber-optic tubes would weaken a material, they can actually strengthen it by turning it into a fiber-reinforced composite (effectively, they serve as the fibers you'd get in something like fiberglass, or like the steel "rebar" rods in reinforced concrete ). When they cool down, the original the Psychological Theories on Juvenile Delinquencies polymer reforms, reversing the damage. Systems like this are sometimes known as autonomous adaptive structures and have been pioneered by materials engineer Henry Sodano.
