The most common forms of uranium oxide are triuranium octoxide (U
3O
8) and UO
2. Both oxide forms are solids that have low solubility in water and are relatively stable over a wide range of environmental conditions. Triuranium octoxide is (depending on conditions) the most stable compound of uranium and is the form most commonly found in nature. Uranium dioxide is the form in which uranium is most commonly used as a nuclear reactor fuel. At ambient temperatures, UO
2 will gradually convert to U
3O
8. Because of their stability, uranium oxides are generally considered the preferred chemical form for storage or disposal.
In what form is uranium most often used as fuel for nuclear reactors?
Uranium dioxide

Phonology also includes topics such as phonotactics (the phonological constraints on what sounds can appear in what positions in a given language) and phonological alternation (how the pronunciation of a sound changes through the application of phonological rules, sometimes in a given order which can be feeding or bleeding,) as well as prosody, the study of suprasegmentals and topics such as stress and intonation.
Aside from bleeding what is an order of rules that define how pronunciation of a sound changes?
feeding

Under the provisions of the 1833 India Act, control of Saint Helena was passed from the East India Company to the British Crown, becoming a crown colony. Subsequent administrative cost-cutting triggered the start of a long-term population decline whereby those who could afford to do so tended to leave the island for better opportunities elsewhere. The latter half of the 19th century saw the advent of steam ships not reliant on trade winds, as well as the diversion of Far East trade away from the traditional South Atlantic shipping lanes to a route via the Red Sea (which, prior to the building of the Suez Canal, involved a short overland section). These factors contributed to a decline in the number of ships calling at the island from 1,100 in 1855 to only 288 in 1889.
By 1889 how many ships were going to the island?
288
