Calculate the reflectance for specific conditions. For example, say that a polished gold surface subjected to direct radiation with a wavelength of 480 nanometers reflects about 60 percent of that radiation. In this case, the reflectance would be q(y) = (Gr(y)/Gi(y))^2 = .6^2 = .36, or about 36 percent.
axial skeleton - the part of the skeleton that includes the skull and spinal column and sternum and ribs. breastbone, sternum - the flat bone that articulates with the clavicles and the first seven pairs of ribs. skull - the bony skeleton of the head of vertebrates.
The human skeleton is the internal framework of the body. It is composed of 270 bones at birth â this total decreases to 206 bones by adulthood after some bones have fused together. The bone mass in the skeleton reaches maximum density around age 30. The human skeleton can be divided into the axial skeleton and the appendicular skeleton. The axial skeleton is formed by the vertebral column, the rib cage and the skull.
