Related terms: PVD, peripheral arterial disease, PAD, venous thrombosis, deep vein thrombosis, DVT. Peripheral vascular disease (PVD) involves damage to or blockage in the blood vessels distant from your heartâthe peripheral arteries and veins.Your peripheral arteries and veins carry blood to and from your arm and leg muscles and the organs in and below your stomach area.hen PVD affects only the arteries and not the veins, it is called peripheral arterial disease (PAD). The main forms that PVD may take include blood clots (for example, deep vein thrombosis or DVT), swelling (inflammation), or narrowing and blockage of the blood vessels.
THE VELOCITY OF LIGHT AND MAXWELL'S CONSTANT. The use of the velocity of light, or more generally, the velocity of propagation in vacuum of the electromagnetic waves as a fundamental constant, comes from James Maxwell's Electromagnetic Theory.
The Schwarzchild radius is given by the equation 2GM/c squared. Since G, the gravitational parameter and c, the speed of light in a vacuum are constant, the only variable for the radius is the mass of the black hole: the more mass, the larger the raduis. add a comment.+1 vote!nswer by gmedich (93).
