Peripheral Arterial Disease (PAD) is a progressive atherosclerotic disorder which
is defined as any pathologic process obstructing the blood flow of the arteries supplying
the lower extremities. Moderate stenoses mayor may not be...
Hemolysis (red cells lysis) caused by fluid stresses in flows within hypodermic needles, blood pumps, artificial hearts and other cardiovascular devices, is one of the major concerns during the design and use of cardiovascular or blood-processing...
In the electronic and microfabrication industry, die separation is one of the most critical steps in producing an undamaged, stand-alone micro-scale device. For silicon based devices, it is the predominant step governing resistance to die failure...
