In Singapore, a Junior College (JC) is equivalent to a sixth form college in the United Kingdom. After the GCE 'O' level examinations in Secondary 4 or 5, students may apply for admission to either a JC or a polytechnic.
Imodium may also be used to decrease the amount of discharge in patients who have undergone an ileostomy (a procedure to move waste out of the body when the colon or rectum is not working properly) or to treat diarrhea in patients with inflammatory bowel disease (IBD).
Thorium is also used to coat tungsten filaments used in electronic devices, such at television sets. When bombarded with neutrons, thorium-232 becomes thorium-233, which eventually decays into uranium-233 through a series of beta decays. Uranium-233 is a fissionable material and can be used as a nuclear fuel. Thorium oxide (ThO2), one of thorium's compounds, has many uses. It is primarily used in a type of lantern mantel known as a Welsbach mantle.
