internal fixation includes the use of pins, screws, staples, rods, and plates that are inserted into the bone to maintain alignment. when the fractured bone is in good alignment so that no manipulation is necessary, internal fixation may be used to stabilize the bone without any fracture reduction being performed.
What you see is only what you see. May 22, 2015. Color perception is an ancient and active philosophical problem. Itâs an instance of the wider category of sensory perception, but since the color spectrum fits on a single line (unlike, say, touch and taste), it has always been of particular interest.
Color Perception. The properties of color which are inherently distinguishable by the human eye are hue, saturation, and brightness. While we know that the spectral colors can be one-to-one correlated with light wavelength, the perception of light with multiple wavelengths is more complicated. It is found that many different combinations of light wavelengths can produce the same perception of color. This can be put in perspective with the CIE chromaticity diagram. The white or achromatic point E can also be achieved with many different mixtures of light, e.g. with complementary colors.
