Henry Jones Shrapnell tympanic membrane is known as "Shrapnell's membrane". During the same year, Shrapnell published two other articles in the same journal, these being in regards to the function of the tympanic membrane and the nerves of the ear. In 1833, he published an article (again in the same journal) on the anatomy of the incus. Henry Jones Shrapnell Henry Jones Shrapnell (1792–1834) was an English anatomist. For a period of time during his career he was a colleague to Edward Jenner (1749-1823), creator of the vaccine for smallpox. Shrapnell is remembered for his pioneer work in otology. He was the first
Membrane operating conditions, cost and performance, it should prevented, and if necessary, removed. Optimizing the operation conditions is important to prevent fouling. However, if fouling has already taken place, it should be removed by using physical or chemical cleaning. Physical cleaning techniques for membrane include membrane relaxation and membrane backwashing. Chemical cleaning. Relaxation and backwashing effectiveness will decrease with operation time as more irreversible fouling accumulates on the membrane surface. Therefore, besides the physical cleaning, chemical cleaning may also be recommended. They include: Optimizing the operation condition. Several mechanisms can be carried out to optimize the operation conditions of the membrane
