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.
A deep vein thrombosis (DVT) is a potentially deadly condition caused by a blood clot that forms in a vein - most commonly the deep veins in the legs. This clot formation can happen if the vein is damaged or if the blood flow in the vein is slow or stops. DVT can cause pain and swelling in the leg, but many times it produces no symptoms. If the clot breaks off and travels in the bloodstream, it can cause damage to the lungs. When a blood clot travels to the lungs, it is called a pulmonary embolism (PE). A PE often causes shortness of breath and chest pain. If the lung damage is severe, it can kill people very quickly, even before treatment can be given. For this reason, every effort should be made to prevent a DVT before it happens.
