Problem: Capacitor:

Several other types of capacitor are available for specialist applications. Supercapacitors store large amounts of energy. Supercapacitors made from carbon aerogel, carbon nanotubes, or highly porous electrode materials, offer extremely high capacitance (up to 5 kF as of 2010[update]) and can be used in some applications instead of rechargeable batteries. Alternating current capacitors are specifically designed to work on line (mains) voltage AC power circuits. They are commonly used in electric motor circuits and are often designed to handle large currents, so they tend to be physically large. They are usually ruggedly packaged, often in metal cases that can be easily grounded/earthed. They also are designed with direct current breakdown voltages of at least five times the maximum AC voltage.

Problem: Due to many centuries of intensive settlement, most of the area is shaped by human influence. The original natural vegetation of Thuringia is forest with beech as its predominant species, as can still be found in the Hainich mountains today. In the uplands, a mixture of beech and spruce would be natural. However, most of the plains have been cleared and are in intensive agricultural use while most of the forests are planted with spruce and pine. Since 1990, Thuringia's forests have been managed aiming for a more natural and tough vegetation more resilient to climate change as well as diseases and vermin. In comparison to the forest, agriculture is still quite conventional and dominated by large structures and monocultures. Problems here are caused especially by increasingly prolonged dry periods during the summer months.
What has been the aim for the Thuringian forests since 1970?

In the nineteenth century Burke was praised by both liberals and conservatives. Burke's friend Philip Francis wrote that Burke "was a man who truly & prophetically foresaw all the consequences which would rise from the adoption of the French principles" but because Burke wrote with so much passion, people were doubtful of his arguments. William Windham spoke from the same bench in the House of Commons as Burke had, when he had separated from Fox, and an observer said Windham spoke "like the ghost of Burke" when he made a speech against peace with France in 1801. William Hazlitt, a political opponent of Burke, regarded him as amongst his three favourite writers (the others being Junius and Rousseau), and made it "a test of the sense and candour of any one belonging to the opposite party, whether he allowed Burke to be a great man". William Wordsworth was originally a supporter of the French Revolution and attacked Burke in 'A Letter to the Bishop of Llandaff' (1793), but by the early nineteenth century he had changed his mind and came to admire Burke. In his Two Addresses to the Freeholders of Westmorland Wordsworth called Burke "the most sagacious Politician of his age" whose predictions "time has verified". He later revised his poem The Prelude to include praise of Burke ("Genius of Burke! forgive the pen seduced/By specious wonders") and portrayed him as an old oak. Samuel Taylor Coleridge came to have a similar conversion: he had criticised Burke in The Watchman, but in his Friend (180910) Coleridge defended Burke from charges of inconsistency. Later, in his Biographia Literaria (1817) Coleridge hails Burke as a prophet and praises Burke for referring "habitually to principles. He was a scientific statesman; and therefore a seer". Henry Brougham wrote of Burke: "... all his predictions, save one momentary expression, had been more than fulfilled: anarchy and bloodshed had borne sway in France; conquest and convulsion had desolated Europe...the providence of mortals is not often able to penetrate so far as this into futurity". George Canning believed that Burke's Reflections "has been justified by the course of subsequent events; and almost every prophecy has been strictly fulfilled". In 1823 Canning wrote that he took Burke's "last works and words [as] the manual of my politics". The Conservative Prime Minister Benjamin Disraeli "was deeply penetrated with the spirit and sentiment of Burke's later writings".
When did Wordsworth initially attack Burke?
A: 1793

Context and question: On 5 July 2004, the BBC celebrated the fiftieth anniversary of its television news bulletins (although it had produced the Television Newsreel for several years before 1954). This event was marked by the release of a DVD, which showed highlights of the BBC's television coverage of significant events over the half-century, as well as changes in the format of the BBC television news; from the newsreel format of the first BBC Television News bulletins, to the 24-hour, worldwide news coverage available in 2004. A special edition of Radio Times was also produced, as well as a special section of the BBC News Online website. In 2005 the pioneering BBC television series Little Angels won a BAFTA award. Little Angels was the first reality parenting show and its most famous episode saw Welsh actress Jynine James try to cope with the tantrums of her six-year-old son.
When was the 50th anniversary of BBC news broadcasts?
Answer: 5 July 2004

Question: Before mechanical printing, literature was copied by hand, and many variations were introduced by copyists. The age of printing made the scribal profession effectively redundant. Printed editions, while less susceptible to the proliferation of variations likely to arise during manual transmission, are nonetheless not immune to introducing variations from an author's autograph. Instead of a scribe miscopying his source, a compositor or a printing shop may read or typeset a work in a way that differs from the autograph. Since each scribe or printer commits different errors, reconstruction of the lost original is often aided by a selection of readings taken from many sources. An edited text that draws from multiple sources is said to be eclectic. In contrast to this approach, some textual critics prefer to identify the single best surviving text, and not to combine readings from multiple sources.
Is there an answer to this question: How do differences in works arise when using a printing press?

Answer: a compositor or a printing shop may read or typeset a work in a way that differs from the autograph

The Somali flag is an ethnic flag conceived to represent ethnic Somalis. It was created in 1954 by the Somali scholar Mohammed Awale Liban, after he had been selected by the labour trade union of the Trust Territory of Somalia to come up with a design. Upon independence in 1960, the flag was adopted as the national flag of the nascent Somali Republic. The five-pointed Star of Unity in the flag's center represents the Somali ethnic group inhabiting the five territories in Greater Somalia.
What is the star at the center of the Somali flag called?
A:
Star of Unity
