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.
Is there an answer to this question: Entrapment pumps often work without seals, moving parts and what else?

Answer: no vibration.

Question: More recently, films such as Das Boot (1981), The Never Ending Story (1984) Run Lola Run (1998), Das Experiment (2001), Good Bye Lenin! (2003), Gegen die Wand (Head-on) (2004) and Der Untergang (Downfall) (2004) have enjoyed international success. In 2002 the Academy Award for Best Foreign Language Film went to Caroline Link's Nowhere in Africa, in 2007 to Florian Henckel von Donnersmarck's The Lives of Others. The Berlin International Film Festival, held yearly since 1951, is one of the world's foremost film and cinema festivals.
Is there an answer to this question: What film festival was held yearly until 1951?

Answer: unanswerable

Run entirely by undergraduates, Politics & Policy publishes several times a week with material ranging from short summaries of events to extended research pieces. The organization is funded in part by the Buffett Center.
Is there an answer to this question: How often is Politics & Policy published?

Answer: several times a week

Question: In Latin, on the other hand, the [First name] Cardinal [Surname] order is used in the proclamation of the election of a new pope by the cardinal protodeacon: "Annuntio vobis gaudium magnum; habemus Papam: Eminentissimum ac Reverendissimum Dominum, Dominum (first name) Sanctae Romanae Ecclesiae Cardinalem (last name), ..." (Meaning: "I announce to you a great joy; we have a Pope: The Most Eminent and Most Reverend Lord, Lord (first name) Cardinal of the Holy Roman Church (last name), ...") This assumes that the new pope had been a cardinal just before becoming pope; the most recent election of a non-cardinal as pope was in 1378.
Is there an answer to this question: What way is used in the proclamation of the election of a new nun in Latin?

Answer:
unanswerable
