1 Capillary Refill: Push on the tip of the great toe or the nail bed until blanching occurs. 2  Then release and note how long it takes for the red color to return, a reflection of blood inflow to the distal aspect of the lower extremity. Pulses are rated on a scale ranging from 0 (not palpable) to 2+ (normal). 2  As with edema, this is very subjective and it will take you a while to develop a sense of relative values. 3  In the event that the pulse is not palpable, the doppler signal generated is also rated, ranging again from 0 to 2+.
Just how small is ânano?â In the International System of Units, the prefix nano means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter. The illustration below has three visual examples of the size and the scale of nanotechnology, showing just how small things at the nanoscale actually are.
Question: 1. How many nanometers are there in one meter? The answer has units [nm/m]. - 106 - 10-6 - 103 - ... 1. How many nanometers are there in one meter? The answer has units [nm/m]. - 106 - 10-6 - 103 - 10-3 - 10-9 - 109 - 103/109 - 109/103. 2. What does ? represent in this experiment? - wavelength - speed of light - Period (T) - da'... ? = da' baby sheep - frequency (f) - wave speed. 3. The purpose of the Laser Diffraction lab is to: - measure the spacing between the slits
