Context and question: Mission work in Samoa had begun in late 1830 by John Williams, of the London Missionary Society arriving in Sapapali'i from The Cook Islands and Tahiti. According to Barbara A. West, "The Samoans were also known to engage in ‘headhunting', a ritual of war in which a warrior took the head of his slain opponent to give to his leader, thus proving his bravery." However, Robert Louis Stevenson, who lived in Samoa from 1889 until his death in 1894, wrote in A Footnote to History: Eight Years of Trouble in Samoa, "… the Samoans are gentle people."
What work did Barbara A. West do in the late 1830's?
Answer: unanswerable
Context and question: The above explanation is merely a simple introduction to vacuum pumping, and is not representative of the entire range of pumps in use. Many variations of the positive displacement pump have been developed, and many other pump designs rely on fundamentally different principles. Momentum transfer pumps, which bear some similarities to dynamic pumps used at higher pressures, can achieve much higher quality vacuums than positive displacement pumps. Entrapment pumps can capture gases in a solid or absorbed state, often with no moving parts, no seals and no vibration. None of these pumps are universal; each type has important performance limitations. They all share a difficulty in pumping low molecular weight gases, especially hydrogen, helium, and neon.
What other pump do entrapment pumps have similarities to?
