(20) Using the histochemical stains aluminon, solochrome azurine and solochrome cyanine, intracellular binding of aluminium was examined in the mucosa of the stomach, duodenum, jejunum and ileum of adult rats.
Photography
Definition:
(n.) The science which relates to the action of light on sensitive bodies in the production of pictures, the fixation of images, and the like.
(n.) The art or process of producing pictures by this action of light.
Example Sentences:

(2) The whole film is primarily shown from the character's perspective, so 70% of the process involved working with the director of photography [Maxime Alexandre].
(3) The art Kennard produced formed the basis of his career, as he recounted later: “I studied as a painter, but after the events of 1968 I began to look for a form of expression that could bring art and politics together to a wider audience … I found that photography wasn’t as burdened with similar art historical associations.” The result was his STOP montage series.
