TPO Roof Replaces Leaking Inverted Roof-Membrane Assembly System. The problematic roof was an inverted roof-membrane assembly (IRMA), which consisted of a built-up membrane installed over a structural concrete slab and topped by insulation.
Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot forms in a deep vein. These clots usually develop in the lower leg, thigh, or pelvis, but they can also occur in the arm.
While not likely to be sudden and bilateral--this is potentially life threatening. Essentially a DVT is a blood clot that spontaneously forms in the venous system (the vessels that bring blood from the muscles back to the heart). These clots can form from multiple conditions--the two most common are a thrombophilia (or blood clotting disorder) or an undiagnosed cancer.
