Clinically, patients suffer from a host of seemingly unrelated maladies, from pain episodes to strokes, life-threatening infections and pulmonary hypertension.
The clinical consequences of arterial thrombosis are heart attacks, strokes and renal disease.
We have painted on a large canvas, and used broad brush strokes.
Written expressions are typically even more incoherent than spoken utterances, and may contain perseverations of words and individual pencil strokes.
Both features favor long, extended grinding strokes instead of the shor t, downward crushing strokes of less intensive grinding.
The death rate from strokes has almost halved since 1972, and there has also been a significant reduction in deaths from heart disease.
In this project, three cylinders with different strokes, 25, 100, and 200 mm all having a 25 mm diameter, are used.
The reasons for the success of these actuators are large magnetic forces, large and adjustable strokes, and a very robust and stable design.
