In 2010, there were 1.2 million people living in the greater Palermo area, 655,875 of which resided in the City boundaries, of whom 47.4% were male and 52.6% were female. People under age 15 totalled 15.6% compared to pensioners who composed 17.2% of the population. This compares with the Italian average of 14.1% people under 15 years and 20.2% pensioners. The average age of a Palermo resident is 40.4 compared to the Italian average of 42.8. In the ten years between 2001 and 2010, the population of Palermo declined by 4.5%, while the population of Italy, as a whole, grew by 6.0%. The reason for Palermo's decline is a population flight to the suburbs, and to Northern Italy. The current birth rate of Palermo is 10.2 births per 1,000 inhabitants compared to the Italian average of 9.3 births.

The most popular term in English-speaking Canada used for a drinking establishment was "tavern", until the 1970s when the term "bar" became widespread as in the United States. In the 1800s the term used was "public house" as in England but "pub culture" did not spread to Canada. A fake "English looking" pub trend started in the 1990s, built into existing storefronts, like regular bars. Most universities in Canada have campus pubs which are central to student life, as it would be bad form just to serve alcohol to students without providing some type of basic food. Often these pubs are run by the student's union. The gastropub concept has caught on, as traditional British influences are to be found in many Canadian dishes. There are now pubs in the large cities of Canada that cater to anyone interested in a "pub" type drinking environment.[citation needed]

The curious location on Catalina Island stemmed from Cubs owner William Wrigley Jr.'s then-majority interest in the island in 1919. Wrigley constructed a ballpark on the island to house the Cubs in spring training: it was built to the same dimensions as Wrigley Field. (The ballpark is long gone, but a clubhouse built by Wrigley to house the Cubs exists as the Catalina County Club.) However, by 1951 the team chose to leave Catalina Island and spring training was shifted to Mesa, Arizona. The Cubs' 30-year association with Catalina is chronicled in the book, The Cubs on Catalina, by Jim Vitti . . . which was named International 'Book of the Year' by The Sporting News.

In 2005, Argentina's indigenous population (known as pueblos originarios) numbered about 600,329 (1.6% of total population); this figure includes 457,363 people who self-identified as belonging to an indigenous ethnic group and 142,966 who identified themselves as first-generation descendants of an indigenous people. The ten most populous indigenous peoples are the Mapuche (113,680 people), the Kolla (70,505), the Toba (69,452), the Guaraní (68,454), the Wichi (40,036), the Diaguita-Calchaquí (31,753), the Mocoví (15,837), the Huarpe (14,633), the Comechingón (10,863) and the Tehuelche (10,590). Minor but important peoples are the Quechua (6,739), the Charrúa (4,511), the Pilagá (4,465), the Chané (4,376), and the Chorote (2,613). The Selknam (Ona) people are now virtually extinct in its pure form. The languages of the Diaguita, Tehuelche, and Selknam nations have become extinct or virtually extinct: the Cacán language (spoken by Diaguitas) in the 18th century and the Selknam language in the 20th century; one Tehuelche language (Southern Tehuelche) is still spoken by a handful of elderly people.

On October 9, 2006 at 6:00 a.m., the network switched to a 24-hour schedule, becoming one of the last major English-language broadcasters to transition to such a schedule. Most CBC-owned stations previously signed off the air during the early morning hours (typically from 1:00 a.m. to 6:00 a.m.). Instead of the infomercials aired by most private stations, or a simulcast of CBC News Network in the style of BBC One's nightly simulcast of BBC News Channel, the CBC uses the time to air repeats, including local news, primetime series, movies and other programming from the CBC library. Its French counterpart, Ici Radio-Canada Télé, still signs off every night.

To minimize overall weight and size, miniature PM motors may use high energy magnets made with neodymium or other strategic elements; most such are neodymium-iron-boron alloy. With their higher flux density, electric machines with high-energy PMs are at least competitive with all optimally designed singly-fed synchronous and induction electric machines. Miniature motors resemble the structure in the illustration, except that they have at least three rotor poles (to ensure starting, regardless of rotor position) and their outer housing is a steel tube that magnetically links the exteriors of the curved field magnets.

Madonna embarked on the Confessions Tour in May 2006, which had a global audience of 1.2 million and grossed over $193.7 million, becoming the highest-grossing tour to that date for a female artist. Madonna used religious symbols, such as the crucifix and Crown of Thorns, in the performance of "Live to Tell". It caused the Russian Orthodox Church and the Federation of Jewish Communities of Russia to urge all their members to boycott her concert. At the same time, the International Federation of the Phonographic Industry (IFPI) announced officially that Madonna had sold over 200 million copies for her albums alone worldwide.

Financial problems and a reduction in tourism led to Norfolk Island's administration appealing to the Australian federal government for assistance in 2010. In return, the islanders were to pay income tax for the first time but would be eligible for greater welfare benefits. However, by May 2013 agreement had not been reached and islanders were having to leave to find work and welfare. An agreement was finally signed in Canberra on 12 March 2015 to replace self-government with a local council but against the wishes of the Norfolk Island government. A majority of Norfolk Islanders have objected to the Australian plan to make changes to Norfolk Island without first consulting them and allowing their say with 68% of voters against forced changes.

In 1998, Netscape launched what was to become the Mozilla Foundation in an attempt to produce a competitive browser using the open source software model. That browser would eventually evolve into Firefox, which developed a respectable following while still in the beta stage of development; shortly after the release of Firefox 1.0 in late 2004, Firefox (all versions) accounted for 7% of browser use. As of August 2011, Firefox has a 28% usage share.

The Compact Disc is an evolution of LaserDisc technology, where a focused laser beam is used that enables the high information density required for high-quality digital audio signals. Prototypes were developed by Philips and Sony independently in the late 1970s. In 1979, Sony and Philips set up a joint task force of engineers to design a new digital audio disc. After a year of experimentation and discussion, the Red Book CD-DA standard was published in 1980. After their commercial release in 1982, compact discs and their players were extremely popular. Despite costing up to $1,000, over 400,000 CD players were sold in the United States between 1983 and 1984. The success of the compact disc has been credited to the cooperation between Philips and Sony, who came together to agree upon and develop compatible hardware. The unified design of the compact disc allowed consumers to purchase any disc or player from any company, and allowed the CD to dominate the at-home music market unchallenged.

Question: Who created Compact Disc prototypes in the 1970s?
Answer: Philips and Sony.

In February 1907, the Royal Dutch Shell Group was created through the amalgamation of two rival companies: the Royal Dutch Petroleum Company of the Netherlands and the "Shell" Transport and Trading Company Ltd of the United Kingdom. It was a move largely driven by the need to compete globally with Standard Oil. The Royal Dutch Petroleum Company was a Dutch company founded in 1890 to develop an oilfield in Sumatra, and initially led by August Kessler, Hugo Loudon, and Henri Deterding. The "Shell" Transport and Trading Company (the quotation marks were part of the legal name) was a British company, founded in 1897 by Marcus Samuel, 1st Viscount Bearsted, and his brother Samuel Samuel. Their father had owned an antique company in Houndsditch, London, which expanded in 1833 to import and sell sea-shells, after which the company "Shell" took its name.

As the economy and the middle class expanded, there was an increasing number of amateur musicians. One manifestation of this involved women, who became more involved with music on a social level. Women were already engaged in professional roles as singers, and increased their presence in the amateur performers' scene, especially with keyboard music. Music publishers begin to print music that amateurs could understand and play. The majority of the works that were published were for keyboard, voice and keyboard, and chamber ensemble. After these initial genres were popularized, from the mid-century on, amateur groups sang choral music, which then became a new trend for publishers to capitalize on. The increasing study of the fine arts, as well as access to amateur-friendly published works, led to more people becoming interested in reading and discussing music. Music magazines, reviews, and critical works which suited amateurs as well as connoisseurs began to surface.

Mohinga is the traditional breakfast dish and is Myanmar's national dish. Seafood is a common ingredient in coastal cities such as Sittwe, Kyaukpyu, Mawlamyaing (formerly Moulmein), Mergui (Myeik) and Dawei, while meat and poultry are more commonly used in landlocked cities like Mandalay. Freshwater fish and shrimp have been incorporated into inland cooking as a primary source of protein and are used in a variety of ways, fresh, salted whole or filleted, salted and dried, made into a salty paste, or fermented sour and pressed.

Besides the bit rate of an encoded piece of audio, the quality of MP3 files also depends on the quality of the encoder itself, and the difficulty of the signal being encoded. As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders may feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two different MP3 encoders at about 128 kbit/s, one scored 3.66 on a 1–5 scale, while the other scored only 2.22.

Question: The MP3 standard allows encoders to have a lot of freedom with which aspect of encoding?
Answer: encoding algorithms.

Neurotransmitters are chemicals that are released at synapses when an action potential activates them—neurotransmitters attach themselves to receptor molecules on the membrane of the synapse's target cell, and thereby alter the electrical or chemical properties of the receptor molecules. With few exceptions, each neuron in the brain releases the same chemical neurotransmitter, or combination of neurotransmitters, at all the synaptic connections it makes with other neurons; this rule is known as Dale's principle. Thus, a neuron can be characterized by the neurotransmitters that it releases. The great majority of psychoactive drugs exert their effects by altering specific neurotransmitter systems. This applies to drugs such as cannabinoids, nicotine, heroin, cocaine, alcohol, fluoxetine, chlorpromazine, and many others.

Question: Neurons that release the same chemicals are following what rule?
Answer: Dale's principle.

In politics, corruption undermines democracy and good governance by flouting or even subverting formal processes. Corruption in elections and in the legislature reduces accountability and distorts representation in policymaking; corruption in the judiciary compromises the rule of law; and corruption in public administration results in the inefficient provision of services. It violates a basic principle of republicanism regarding the centrality of civic virtue.

For vertebrates, the early stages of neural development are similar across all species. As the embryo transforms from a round blob of cells into a wormlike structure, a narrow strip of ectoderm running along the midline of the back is induced to become the neural plate, the precursor of the nervous system. The neural plate folds inward to form the neural groove, and then the lips that line the groove merge to enclose the neural tube, a hollow cord of cells with a fluid-filled ventricle at the center. At the front end, the ventricles and cord swell to form three vesicles that are the precursors of the forebrain, midbrain, and hindbrain. At the next stage, the forebrain splits into two vesicles called the telencephalon (which will contain the cerebral cortex, basal ganglia, and related structures) and the diencephalon (which will contain the thalamus and hypothalamus). At about the same time, the hindbrain splits into the metencephalon (which will contain the cerebellum and pons) and the myelencephalon (which will contain the medulla oblongata). Each of these areas contains proliferative zones where neurons and glial cells are generated; the resulting cells then migrate, sometimes for long distances, to their final positions.

Question: The vesicle that contains the cerebral cortex is which one?
Answer: telencephalon.

In December 1547, Francis was in Malacca (Malaysia) waiting to return to Goa (India) when he met a low-ranked samurai named Anjiro (possibly spelled "Yajiro"). Anjiro was not an intellectual, but he impressed Xavier because he took careful notes of everything he said in church. Xavier made the decision to go to Japan in part because this low-ranking samurai convinced him in Portuguese that the Japanese people were highly educated and eager to learn. They were hard workers and respectful of authority. In their laws and customs they were led by reason, and, should the Christian faith convince them of its truth, they would accept it en masse.

Players may only be transferred during transfer windows that are set by the Football Association. The two transfer windows run from the last day of the season to 31 August and from 31 December to 31 January. Player registrations cannot be exchanged outside these windows except under specific licence from the FA, usually on an emergency basis. As of the 2010–11 season, the Premier League introduced new rules mandating that each club must register a maximum 25-man squad of players aged over 21, with the squad list only allowed to be changed in transfer windows or in exceptional circumstances. This was to enable the 'home grown' rule to be enacted, whereby the League would also from 2010 require at least 8 of the named 25 man squad to be made up of 'home-grown players'.

Irir Samaale, the oldest common ancestor of several Somali clans, is generally regarded as the source of the ethnonym Somali. The name "Somali" is, in turn, held to be derived from the words soo and maal, which together mean "go and milk" — a reference to the ubiquitous pastoralism of the Somali people. Another plausible etymology proposes that the term Somali is derived from the Arabic for "wealthy" (dhawamaal), again referring to Somali riches in livestock.

In 1926, Universal opened a production unit in Germany, Deutsche Universal-Film AG, under the direction of Joe Pasternak. This unit produced three to four films per year until 1936, migrating to Hungary and then Austria in the face of Hitler's increasing domination of central Europe. With the advent of sound, these productions were made in the German language or, occasionally, Hungarian or Polish. In the U.S., Universal Pictures did not distribute any of this subsidiary's films, but at least some of them were exhibited through other, independent, foreign-language film distributors based in New York, without benefit of English subtitles. Nazi persecution and a change in ownership for the parent Universal Pictures organization resulted in the dissolution of this subsidiary.

Compression efficiency of encoders is typically defined by the bit rate, because compression ratio depends on the bit depth and sampling rate of the input signal. Nevertheless, compression ratios are often published. They may use the Compact Disc (CD) parameters as references (44.1 kHz, 2 channels at 16 bits per channel or 2×16 bit), or sometimes the Digital Audio Tape (DAT) SP parameters (48 kHz, 2×16 bit). Compression ratios with this latter reference are higher, which demonstrates the problem with use of the term compression ratio for lossy encoders.

Question: What can CD parameters be used as references for?
Answer: compression ratios.

In the United States, Lindlof and Taylor write, "Cultural studies [were] grounded in a pragmatic, liberal-pluralist tradition". The American version of cultural studies initially concerned itself more with understanding the subjective and appropriative side of audience reactions to, and uses of, mass culture; for example, American cultural-studies advocates wrote about the liberatory aspects of fandom.[citation needed] The distinction between American and British strands, however, has faded.[citation needed] Some researchers, especially in early British cultural studies, apply a Marxist model to the field. This strain of thinking has some influence from the Frankfurt School, but especially from the structuralist Marxism of Louis Althusser and others. The main focus of an orthodox Marxist approach concentrates on the production of meaning. This model assumes a mass production of culture and identifies power as residing with those producing cultural artifacts. In a Marxist view, those who control the means of production (the economic base) essentially control a culture.[citation needed] Other approaches to cultural studies, such as feminist cultural studies and later American developments of the field, distance themselves from this view. They criticize the Marxist assumption of a single, dominant meaning, shared by all, for any cultural product. The non-Marxist approaches suggest that different ways of consuming cultural artifacts affect the meaning of the product. This view comes through in the book Doing Cultural Studies: The Story of the Sony Walkman (by Paul du Gay et al.), which seeks to challenge the notion that those who produce commodities control the meanings that people attribute to them. Feminist cultural analyst, theorist and art historian Griselda Pollock contributed to cultural studies from viewpoints of art history and psychoanalysis. The writer Julia Kristeva is among influential voices at the turn of the century, contributing to cultural studies from the field of art and psychoanalytical French feminism.[citation needed]

The effects of local surface low pressure are extremely limited because upper-level subsidence still continues to block any form of air ascent. Also, to be protected against rain-bearing weather systems by the atmospheric circulation itself, the desert is made even drier by his geographical configuration and location. Indeed, the extreme aridity of the Sahara can't be only explained by the subtropical high pressure. The Atlas Mountains, found in Algeria, Morocco and Tunisia also help to enhance the aridity of the northern part of the desert. These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.

Question: What is blocked due to local surface low pressure?
Answer: air ascent.
