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 vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit. physical color is a combination of pure spectral colors (in the visible range). Since there are, in principle, infinitely many distinct spectral colors, the set of all physical colors may be thought of as an infinite-dimensional vector space, in fact a Hilbert space. We call this space H color.
