Question: An infestation of the coconut rhinoceros beetle (CRB), Oryctes rhinoceros, was detected on Guam on September 12, 2007. CRB is not known to occur in the United States except in American Samoa. Delimiting surveys performed September 13–25, 2007 indicated that the infestation was limited to Tumon Bay and Faifai Beach, an area of approximately 900 acres (3.6 km2). Guam Department of Agriculture (GDA) placed quarantine on all properties within the Tumon area on October 5 and later expanded the quarantine to about 2,500 acres (10 km2) on October 25; approximately 0.5 miles (800 m) radius in all directions from all known locations of CRB infestation. CRB is native to Southern Asia and distributed throughout Asia and the Western Pacific including Sri Lanka, Upolu, Samoa, American Samoa, Palau, New Britain, West Irian, New Ireland, Pak Island and Manus Island (New Guinea), Fiji, Cocos (Keeling) Islands, Mauritius, and Reunion.

Question: Studies by Nathaniel Kleitman in 1938 and by Derk-Jan Dijk and Charles Czeisler in the 1990s put human subjects on enforced 28-hour sleep–wake cycles, in constant dim light and with other time cues suppressed, for over a month. Because normal people cannot entrain to a 28-hour day in dim light if at all,[citation needed] this is referred to as a forced desynchrony protocol. Sleep and wake episodes are uncoupled from the endogenous circadian period of about 24.18 hours and researchers are allowed to assess the effects of circadian phase on aspects of sleep and wakefulness including sleep latency and other functions.[page needed]

Answer: What time cycle did studies in 1938 and 1990s use on humans?

For they hold the places, but you the Apostolic Faith. They are, it is true, in the places, but outside of the true Faith; while you are outside the places indeed, but the Faith, within you. Let us consider whether is the greater, the place or the Faith. Clearly the true Faith. Who then has lost more, or who possesses more? He who holds the place, or he who holds the Faith?
