The dicrotic notch represents the nadir point that occurs immediately after the closure of the aortic valves and precedes the secondary dicrotic wave. The T wave represents ventricular repolarization. This is followed by ventricular relaxation, during which the ventricles falls. The dicrotic notch is a short-lived decrease in pressure in the ascending aorta, which occurs following closure of the aortic valve.
Answer:
y = -4/3 x -6
Explanation:
Recall that a parallel line to the one given has to have the same slope. The slope of the line given is "-4/3" (the coefficient that accompanies "x").
Therefore the equation of a parallel line has to be of the form:
y = -4/3 x + b
2 = -4/3 (-6) + b
2 = 24/3 +b
2 = 8 + b
b = 2 - 8
b = -6
So the entire equation now becomes:
y = -4/3 x -6
Answer: a. use of refrigerated clotted blood samples in which complement components coat RBCs in vitro
Explanation:
DAT is direct antiglobulin test. It is also called as Coombs test. It is primarily used for determining the cause of hemolytic anemia. This test looks for the attachment of the antibodies that break apart the red blood cells causing hemolysis.
A false positive DAT result signifies that the eluted antibody cannot bind to the red blood cells. But binding do occur in true positive test.
Thus the result may reflect that it has been conducted on the refrigerated and clotted blood samples yielding a false result in inappropriate results.
