If an autoimmune disease destroys the body's platelets, thrombocytopenia can occur. One example of this type of autoimmune disease is immune thrombocytopenia (ITP). ITP is a bleeding disorder in which the blood doesn't clot as it should. An autoimmune response is thought to cause most cases of ITP.
Mass Loaded Vinyl Noise Barrier. Mass Loaded Vinyl (MLV) is a safe, non-toxic vinyl acoustic noise barrier designed to hang as a limp mass in a variety of soundproofing applications. MLV soundproofing offers an alternative to Lead at a lower price point.
Tuned Mass Dampers >> Home Â» Tuned Mass Dampers A Tuned Mass Damper (TMD) is a mechanical device designed to add damping to a structure for a certain range of exciting frequencies. The extra damping will reduce the movement of the structure to an acceptable level. A tuned mass damper contains a mass that is able to oscillate in the same direction as the structure. The oscillation frequency of the mass can be tuned using springs, suspension bars, or ball transfers. When the structure starts to oscillate, the mass of the TMD will initially remain stationary due to inertia.
