Equivalent depth of water (cm) contained in a 1 m soil profile, if the undisturbed coreis representative of the 1 m soil depth 2. Consider a 1.2 m depth soil profile with 3 layers. The dry bulk density of each layer(top, center, bottom) is 1.20, 1.35, and 1.48 g/cm 3.
Definition. A nuclear stress test measures blood flow to your heart at rest and while your heart is working harder as a result of exertion or medication. The test provides images that can show areas of low blood flow through the heart and damaged heart muscle. The test usually involves taking two sets of images of your heart â one while you're at rest and another after you heart is stressed, either by exercise or medication.
The nuclear stress test may show: 1  Normal blood flow during rest and exercise - this means heart function appears to be normal at all times.  Normal blood flow during rest, abnormal during exercise - part of the patient's heart muscle is not getting sufficient blood during physical or strenuous activity.
