Question: On which platform did ABC create an app for Grey's Anatomy?

ABC has partnered with CafePress and Barco Uniforms to provide branded merchandise through an online store.
The products available include shirts, sweatshirts, kitchen-ware, home-ware, and bags, with the "Grey's Anatomy" logo on it.
Also available are custom unisex scrubs and lab coats in a variety of colors and sizes, designed by Barco.
The merchandise released by ABC is available for purchase at the "Grey's Anatomy" official website, and US$1 from every purchase to Barco's Nightingales Foundation.
Five volumes of the "Grey's Anatomy Original Soundtrack" have been released as of 2011.
For the first two seasons, the show's main title theme was an excerpt from "Cosy in the Rocket", by British duo Psapp; it is featured on the first soundtrack album released via ABC's corporate cousin, Hollywood Records, on September 27, 2005.
The second soundtrack, featuring songs from the series' second season, was released on September 12, 2006, followed by a third soundtrack with music from the third season.
Following the seventh season musical episode "Song Beneath the Song", ""Grey's Anatomy": The Music Event" soundtrack was released, with volume four of the soundtrack released subsequently.
In January 2009, Ubisoft announced that it had signed a licensing agreement with ABC Studios to develop a video game based on "Grey's Anatomy".
Designed for the Wii, Nintendo DS, and PC, "" was released on March 10, 2009.
The game allows the player to assume the role of one of the main characters, making decisions for the character's personal and professional life, and competing in a number of minigames.
It has been criticized by reviewers because of the simplicity of the mini-games and voice actors who do not play the same characters on the series, with Jason Ocampo of "IGN" giving it a 6.0 out of 10 overall rating.
ABC and Nielsen partnered in 2011 to create a "Grey Anatomy" application for Apple's iPad.
The application was designed to allow viewers to participate in polls and learn trivial facts as they watch a live episode.
It uses Nielsen's Media-Sync software to listen for the episode and to post features as the episode progresses.
Article: Magnetic resonance imaging
Section: MRI versus CT

Question: What do the letters CT mean?

MRI and computed tomography (CT) are complementary imaging technologies and each has advantages and limitations for particular applications.
CT is more widely used than MRI in OECD countries with a mean of 132 vs 46 exams per 1000 population performed respectively.
A concern is the potential for CT to contribute to radiation-induced cancer and in 2007 it was estimated that 0.4% of current cancers in the United States were due to CTs performed in the past, and that in the future this figure may rise to 1.5–2% based on historical rates of CT usage.
An Australian study found that one in every 1800 CT scans was associated with an excess cancer.
An advantage of MRI is that no ionizing radiation is used and so it is recommended over CT when either approach could yield the same diagnostic information.
However, although the cost of MRI has fallen, making it more competitive with CT, there are not many common imaging scenarios in which MRI can simply replace CT, although this substitution has been suggested for the imaging of liver disease.
The effect of low doses of radiation on carcinogenesis are also disputed.
Although MRI is associated with biological effects, these have not been proven to cause measurable harm.
In a comparison of possible genotoxic effects of MRI compared with those of CT scans, Knuuti et al.
noted that although previous studies have demonstrated DNA damage associated with MRI, "the long-term biological and clinical significance of DNA double-strand breaks induced by MRI remains unknown".
Iodinated contrast medium is routinely used in CT and the main adverse events are anaphylactoid reactions and nephrotoxicity.
Commonly used MRI contrast agents have a good safety profile but linear non-ionic agents in particular have been implicated in nephrogenic systemic fibrosis in patients with severely impaired renal function.MRI is contraindicated in the presence of MR-unsafe implants, and although these patients may be imaged with CT, beam hardening artefact from metallic devices, such as pacemakers and implantable cardioverter-defibrillators, may also affect image quality.
MRI is a longer investigation than CT and an exam may take between 20 - 40 mins depending on complexity.

Section: Influence

Question: Was Shrek 2 the inspiration for any later films?

Previous films and TV shows, such as "Fractured Fairy Tales" and "The Princess Bride", have parodied the traditional fairy tale.
However, "Shrek" itself has noticeably influenced the current generation of mainstream animated films.
Particularly after "Shrek 2", animated films began to incorporate more pop culture references and end-film musical numbers.
Such elements can be seen in films like "Robots", and "Chicken Little".
It also inspired a number of computer animated films which also spoofed fairy tales, or other related story genres, often including adult-oriented humor, most of which were not nearly as successful as "Shrek", such as "Happily N'Ever After", "Igor", and "Hoodwinked!
".

Section: Visual arts

Question: Which poet was a friend of Almada Negreiros?

Portugal has a rich history in painting.
The first well-known painters date back to the 15th century – like Nuno Gonçalves – were part of the Gothic painting period.
José Malhoa, known for his work "Fado", and Columbano Bordalo Pinheiro (who painted the portraits of Teófilo Braga and Antero de Quental) were both references in naturalist painting.
The 20th century saw the arrival of Modernism, and along with it came the most prominent Portuguese painters: Amadeo de Souza-Cardoso, who was heavily influenced by French painters, particularly by the Delaunays.
Among his best known works is "Canção Popular a Russa e o Fígaro".
Another great modernist painters/writers were Carlos Botelho and Almada Negreiros, friend to the poet Fernando Pessoa, who painted his (Pessoa's) portrait.
He was deeply influenced by both Cubist and Futurist trends.
Prominent international figures in visual arts nowadays include painters Vieira da Silva, Júlio Pomar, Helena Almeida, Joana Vasconcelos, Julião Sarmento and Paula Rego.
Article: Pakistan
Section: Kashmir conflict

Question: is the Kashmir conflict a territorial dispute?

The Kashmir conflict is a territorial dispute between India and Pakistan over the Kashmir region, the most northwesterly region of South Asia.
The two countries have fought at least three wars over Kashmir—the Indo-Pakistani War of 1947, 1965, 1971 and 1999—and several skirmishes over the Siachen Glacier.
India claims the entire state of Jammu and Kashmir and administers approximately 45.1% of the region, including most of Jammu, the Kashmir Valley, Ladakh, and the Siachen Glacier.
India's claim is contested by Pakistan, which controls approximately 38.2% of Kashmir, consisting of Azad Kashmir and the northern areas of Gilgit and Baltistan.
The conflict of Kashmir has its origin in 1947, when British India was separated into the two states of Pakistan and India.
As part of the partition process, both countries had agreed that the rulers of princely states would be allowed to opt for membership of either Pakistan or India, or in special cases to remain independent.
India claims Kashmir on the basis of the Instrument of Accession, a legal agreement with Kashmir's leaders executed by Maharaja Hari Singh, then ruler of Kashmir, agreeing to accede the area to India.
Pakistan claims Kashmir on the basis of a Muslim majority and of geography, the same principles that were applied for the creation of the two independent states.
India referred the dispute to the United Nations on 1 January 1948.
In a resolution in 1948, the UN asked Pakistan to remove most of its troops.
A plebiscite would then be held.
However, Pakistan failed to vacate the region.
A ceasefire was reached in 1949 and a Line of Control was established, dividing Kashmir between the two countries.
Pakistan's position is that the people of Jammu and Kashmir have the right to determine their future through impartial elections as mandated by the United Nations.
India has stated that it believes that Kashmir is an integral part of India, referring to the 1972 Simla Agreement and to the fact that elections take place regularly.
Certain Kashmiri independence groups believe that Kashmir should be independent of both India and Pakistan.

Section: Geography

Question: How many lakes does Switzerland have?

Extending across the north and south side of the Alps in west-central Europe, Switzerland encompasses a great diversity of landscapes and climates on a limited area of .
The population is about 7.9 million, resulting in an average population density of around 190 people per square kilometre (485/sq mi).
The more mountainous southern half of the country is far more sparsely populated than the northern half.
In the largest Canton of Graubünden, lying entirely in the Alps, population density falls to 27 /km² (70 /sq mi).
Switzerland lies between latitudes 45° and 48° N, and longitudes 5° and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss plateau or middleland, and the Jura mountains on the north.
The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area.
Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres.
From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhône, which flow in the four cardinal directions into the whole of Europe.
The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva, Lake Constance and Lake Maggiore.
Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water.
Lakes and glaciers cover about 6% of the national territory.
About a hundred of Switzerland's mountain peaks are close to or higher than .
At , Monte Rosa is the highest, although the Matterhorn () is probably the most famous.
Both are located within the Pennine Alps in the canton of Valais.
The section of the Bernese Alps above the deep glacial Lauterbrunnen valley, containing 72 waterfalls, is well known for the Jungfrau () and Eiger, and the many picturesque valleys in the region.
In the southeast the long Engadin Valley, encompassing the St. Moritz area in canton Graubünden, is also well known; the highest peak in the neighbouring Bernina Alps is Piz Bernina ().
The more populous northern part of the country, comprising about 30% of the country's total area, is called the Middle Land.
It has greater open and hilly landscapes, partly forested, partly open pastures, usually with grazing herds, or vegetables and fruit fields, but it is still hilly.
There are large lakes found here and the biggest Swiss cities are in this area of the country.
The largest lake is Lake Geneva (also called Lac Léman in French), in western Switzerland.
The Rhône River is both the main input and output of Lake Geneva.
Article: 2003 invasion of Iraq
Section: Iraqi drones

Question: What did Colin Powell suggest?

In October 2002, a few days before the US Senate vote on the Authorization for Use of Military Force Against Iraq Resolution, about 75 senators were told in closed session that the Iraqi government had the means of delivering biological and chemical weapons of mass destruction by unmanned aerial vehicle (UAV) drones that could be launched from ships off the US' Atlantic coast to attack US eastern seaboard cities.
Colin Powell suggested in his presentation to the United Nations that UAVs were transported out of Iraq and could be launched against the United States.
In fact, Iraq had no offensive UAV fleet or any capability of putting UAVs on ships.
Iraq's UAV fleet consisted of less than a handful of outdated Czech training drones.
At the time, there was a vigorous dispute within the intelligence community whether the CIA's conclusions about Iraq's UAV fleet were accurate.
The US Air Force agency denied outright that Iraq possessed any offensive UAV capability.
Article: Donatello
Section: Last years in Florence

Question: When did Donatello go back to Florence?

Donatello returned to Florence in 1453.
The Judith and Holofernes, begun for the Duomo di Siena date from 1455 to 1460 but were later acquired by the Medici.
Until 1461, Donatello remained in Siena, where he created a "St. John the Baptist", also for the Duomo, and models for its gates, now lost.
For his last commission in Florence, Donatello produced reliefs for the bronze pulpits in the church of San Lorenzo, with help from students Bartolomeo Bellano and Bertoldo di Giovanni.
Donatello provided the general design and personally executed the "Martyrdom of St. Lawrence" and the "Deposition from the Cross"; he worked on the reliefs of "Christ before Pilate" and "Christ before Caiphus", with Bellano.
This work is characterized by an intense, free, indeed sketchy and suggestively unfinished — in Italian a "non-finito" — technique that heightens the dramatic effect of the scenes and emphasizes their spiritual intensity.
Donatello died in Florence in 1466 and was buried in the Basilica of San Lorenzo, next to Cosimo de' Medici the Elder.
Article: Virus
Section: Weapons

Question: What type of virus was recreated in 1918 in laboratories?

The ability of viruses to cause devastating epidemics in human societies has led to the concern that viruses could be weaponised for biological warfare.
Further concern was raised by the successful recreation of the infamous 1918 influenza virus in a laboratory.
The smallpox virus devastated numerous societies throughout history before its eradication.
There are only two centers in the world that are authorized by the WHO to keep stocks of smallpox virus: the Vector Institute in Russia and the Centers for Disease Control and Prevention in the United States.
However fears that it may be used as a weapon may not be totally unfounded.
As the vaccine for smallpox sometimes had severe side-effects, it is no longer used routinely in any country.
Thus, much of the modern human population has almost no established resistance to smallpox, and would be vulnerable to the virus.

Some of these belong to the Association of International Marathons and Distance Races (AIMS) which has grown since its foundation in 1982 to embrace over 300 member events in 83 countries and territories.
The marathons of Berlin, Boston, Chicago, London, New York City and Tokyo form the World Marathon Majors series, awarding $500,000 annually to the best overall male and female performers in the series.
In 2006, the editors of Runner's World selected a "World's Top 10 Marathons", in which the Amsterdam, Honolulu, Paris, Rotterdam, and Stockholm marathons were featured along with the five mentioned above.
Other notable large marathons include United States Marine Corps Marathon, Los Angeles, and Rome.
The Boston Marathon is the world's oldest annual marathon, inspired by the success of the 1896 Olympic marathon and held since 1897.
The oldest annual marathon in Europe is the Košice Peace Marathon, held since 1924 in Košice, Slovakia.
The historic Polytechnic Marathon was discontinued in 1996.
The Athens Classic Marathon traces the route of the 1896 Olympic course, starting in Marathon on the eastern coast of Attica, site of the Battle of Marathon of 490 B.C.E., and ending at the Panathenaic Stadium in Athens.
The Midnight Sun Marathon is held in Tromsø, Norway at 70 degrees north.
Using unofficial and temporary courses, measured by GPS, races of marathon distance are now held at the North Pole, in Antarctica and over desert terrain.
Other unusual marathons include the Great Wall Marathon on The Great Wall of China, the Big Five Marathon among the safari wildlife of South Africa, the Great Tibetan Marathon – a marathon in an atmosphere of Tibetan Buddhism at an altitude of , and the Polar Circle Marathon on the permanent ice cap of Greenland.

Section: Musical structure

Question: what is Everett's opinion on the chord?

The song is in the key of G and opens on "I'll tell you" with a D-B, B-D melody note drop and rise over a I (G) chord.
Controversy exists over the landmark chord that Lennon stated McCartney hit on the piano while they were composing the song.
Marshall considers it is the minor vi (Em) chord (the third chord in the I-V7-vi (G-D7-Em) progression).
Everett is of the same opinion.
Pedler claims, however, that more surprising is the melody note drop from B to F# against a III7 (B7) chord on "understand".
Music theorists are divided over whether this chord is a iii (Bm), a B major, or a B7 or even a B5 power chord with no major or minor defining third.

Around the world.
Southern Europe.
In Italy, particularly in Palermo, marzipan (') is often shaped and painted with food colorings to resemble fruit—'—especially during the Christmas season and on ' (All Souls' Day) on November 2.
May 9 and 10 are also special days for eating marzipan in Sicily.
In Portugal, where the confection has been made by nuns since olden times, traditional marzipan (') fruit-shaped sweets made in the Algarve region are a very common sweet.
There are other regions, as Toledo in Spain in which marzipan is shaped into simple animal shapes, and usually filled in with egg yolk ("") and sugar.
In Greece and Cyprus, marzipan is made in a variety of shapes and sizes and is almost always left white.
In the islands of the Aegean in particular, white marzipan is considered a wedding treat and is served to guests at wedding feasts.
Article: Taekwondo
Section: Safety

Question: Which body part is the most common location for injuries?

Although taekwondo competitors have an apparently substantial risk of injury, most injuries are minor.
A 2009 meta-analysis reported that an average of about 8% of competitors are injured per exposure to competition.
Age, gender, and level of play did not significantly affect the injury rate.
The legs are the most common location for injuries, and bruising is the most common injury type.
Injuries may occur if students are taught to block punches in a formal manner (chamber position, perfect angles, etc.)
even when sparring.
When comparing the speed of a punch and the reaction time taken to block effectively, it is difficult to block a punch.
Many taekwondo schools teach students blocking for grading and classwork, and dodging or parrying for sparring.
