chronic diffuse inflammatory response of bone to low-grade infection, with inflammatory cell infiltrate, fibrous replacement of marrow, and dense sclerotic masses of trabecular bone. Polymorphonuclear leukocytes, plasma cells, and focal osteoblasts may be present.

Diffraction is the apparent bending and spreading of waves when they meet an obstruction. It can occur with any type of wave, including sound waves, water waves, and electromagnetic waves such as light and radio waves. Diffraction also occurs when any group of waves of a finite size is propagating; for example, a narrow beam of light waves from a laser must, because of diffraction of the beam, eventually diverge into a wider beam at a sufficient distance from the laser. ...
