First Pentium 4 microprocessors, based on Willamette and Northwood cores, as well as some Prescott processors, were referenced by their speed. A - Northwood microprocessors with 512 KB L2 cache (for frequencies 2 GHz and lower), or Prescott CPUs with 1 MB L2 cache (for frequencies higher than 2 GHz).
What is a Superficial Blood Clot? When blood clots in the superficial veins of the leg, it is known as a superficial thrombophlebitis (or commonly, phlebitis). Patients often may experience pain and tenderness on the surface of the leg with appearance of a tender lump or streak. Many times, patients recall a varicose vein in the same area prior to the phlebitis appearing. Varicose veins are a well-recognized risk factor for superficial thrombophlebitis. While phlebitis confined to the surface veins does not pose the same serious risk as DVT, we know that some patients with phlebitis progress to DVT as that surface clot extends to the deep venous system.
Blood Clots. Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.Typically, your body will naturally dissolve the blood clot after the injury has healed.latelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
