The Song dynasty reëstablished unity around 960. Under the Song, the prosperity of South China began to overtake that of North China. After the north was lost to the Jurchen Jin dynasty in 1127 following the Jingkang Incident, Hangzhou became the capital of the Southern Song under the name Lin'an. Renowned for its prosperity and beauty, it may have been the largest city in the world at the time. From then on, north Zhejiang and neighboring south Jiangsu have been synonymous with luxury and opulence in Chinese culture. The Mongol conquest and the establishment of the Yuan dynasty in 1279 ended Hangzhou's political clout, but its economy continued to prosper. Marco Polo visited the city, which he called "Kinsay" (after the Chinese Jingshi, meaning "Capital City") claiming it was "the finest and noblest city in the world".

Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.

Owing to economic conditions and the late 2000s recession, many of the proposed mega casinos never went further than the initial planning stages. One of these developers was Pinnacle Entertainment, who purchased the Sands Atlantic City, only to close it permanently November 11, 2006. The following year, the resort was demolished in a dramatic, Las Vegas styled implosion, the first of its kind in Atlantic City. While Pinnacle Entertainment intended to replace it with a $1.5–2 billion casino resort, the company canceled its construction plans and plans to sell the land. The biggest disappointment was when MGM Resorts International announced that it would pull out of all development for Atlantic City, effectively ending their plans for the MGM Grand Atlantic City.

In 1997, OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the Federal Government. The development of the data standards stem in large measure from new responsibilities to enforce civil rights laws." Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group. Prior to this decision, the Census and other government data collections asked people to report only one race.

Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second and third season, won by Committed and Pentatonix, respectively.

Forest gardening was also being used as a food production system in various parts of the world over this period. Forest gardens originated in prehistoric times along jungle-clad river banks and in the wet foothills of monsoon regions.[citation needed] In the gradual process of families improving their immediate environment, useful tree and vine species were identified, protected and improved, whilst undesirable species were eliminated. Eventually superior foreign species were selected and incorporated into the gardens.

One example of omnidirectional antennas is the very common vertical antenna or whip antenna consisting of a metal rod (often, but not always, a quarter of a wavelength long). A dipole antenna is similar but consists of two such conductors extending in opposite directions, with a total length that is often, but not always, a half of a wavelength long. Dipoles are typically oriented horizontally in which case they are weakly directional: signals are reasonably well radiated toward or received from all directions with the exception of the direction along the conductor itself; this region is called the antenna blind cone or null.

Another example is the practice of compulsory licensing, which is where the law forbids copyright owners from denying a license for certain uses of certain kinds of works, such as compilations and live performances of music. Compulsory licensing laws generally say that for certain uses of certain works, no infringement occurs as long as a royalty, at a rate determined by law rather than private negotiation, is paid to the copyright owner or representative copyright collective. Some fair dealing laws, such as Canada's, include similar royalty requirements.

The bank is based in Frankfurt, the largest financial centre in the Eurozone. Its location in the city is fixed by the Amsterdam Treaty. The bank moved to new purpose-built headquarters in 2014 which were designed a Vienna-based architectural office named Coop Himmelbau. The building is approximately 180 metres (591 ft) tall and will be accompanied with other secondary buildings on a landscaped site on the site of the former wholesale market in the eastern part of Frankfurt am Main. The main construction began in October 2008, and it was expected that the building will become an architectural symbol for Europe. While it was designed to accommodate double the number of staff who operate in the former Eurotower, that building has been retained since the ECB took responsibility for banking supervision and more space was hence required.

The first record of the name Israel (as ysrỉꜣr) occurs in the Merneptah stele, erected for Egyptian Pharaoh Merneptah c. 1209 BCE, "Israel is laid waste and his seed is not." This "Israel" was a cultural and probably political entity of the central highlands, well enough established to be perceived by the Egyptians as a possible challenge to their hegemony, but an ethnic group rather than an organised state; Ancestors of the Israelites may have included Semites native to Canaan and the Sea Peoples. McNutt says, "It is probably safe to assume that sometime during Iron Age a population began to identify itself as 'Israelite'", differentiating itself from the Canaanites through such markers as the prohibition of intermarriage, an emphasis on family history and genealogy, and religion.

Since the 19th century, many if not all presidents were assisted by a central figure or "gatekeeper", sometimes described as the President's Private Secretary, sometimes with no official title at all. Eisenhower formalized this role, introducing the office of White House Chief of Staff – an idea he borrowed from the United States Army. Every president after Lyndon Johnson has also appointed staff to this position. Initially, Gerald Ford and Jimmy Carter tried to operate without a chief of staff, but each eventually appointed one.

In his native Poland, in France, where he composed most of his works, and beyond, Chopin's music, his status as one of music's earliest superstars, his association (if only indirect) with political insurrection, his love life and his early death have made him, in the public consciousness, a leading symbol of the Romantic era. His works remain popular, and he has been the subject of numerous films and biographies of varying degrees of historical accuracy.

Context: 

The majority of insects hatch from eggs. The fertilization and development takes place inside the egg, enclosed by a shell (chorion) that consists of maternal tissue. In contrast to eggs of other arthropods, most insect eggs are drought resistant. This is because inside the chorion two additional membranes develop from embryonic tissue, the amnion and the serosa. This serosa secretes a cuticle rich in chitin that protects the embryo against desiccation. In Schizophora however the serosa does not develop, but these flies lay their eggs in damp places, such as rotting matter. Some species of insects, like the cockroach Blaptica dubia, as well as juvenile aphids and tsetse flies, are ovoviviparous. The eggs of ovoviviparous animals develop entirely inside the female, and then hatch immediately upon being laid. Some other species, such as those in the genus of cockroaches known as Diploptera, are viviparous, and thus gestate inside the mother and are born alive.:129, 131, 134–135 Some insects, like parasitic wasps, show polyembryony, where a single fertilized egg divides into many and in some cases thousands of separate embryos.:136–137 Insects may be univoltine, bivoltine or multivoltine, i.e. they may have one, two or many broods (generations) in a year.

Portugal is a significant European minerals producer and is ranked among Europe's leading copper producers. The nation is also a notable producer of tin, tungsten and uranium. However, the country lacks the potential to conduct hydrocarbon exploration and aluminium, a limitation that has hindered the development of Portugal's mining and metallurgy sectors. Although the country has vast iron and coal reserves—mainly in the north—after the 1974 revolution and the consequent economic globalization, low competitiveness forced a decrease in the extraction activity for these minerals. The Panasqueira and Neves-Corvo mines are among the most recognised Portuguese mines that are still in operation.[citation needed]

The severe weather in the Alps has been studied since the 18th century; particularly the weather patterns such as the seasonal foehn wind. Numerous weather stations were placed in the mountains early in the early 20th century, providing continuous data for climatologists. Some of the valleys are quite arid such as the Aosta valley in Italy, the Maurienne in France, the Valais in Switzerland, and northern Tyrol.

The islands are located about halfway between Hawaii and Australia, north of Nauru and Kiribati, east of the Federated States of Micronesia, and south of the U.S. territory of Wake Island, to which it lays claim. The atolls and islands form two groups: the Ratak (sunrise) and the Ralik (sunset). The two island chains lie approximately parallel to one another, running northwest to southeast, comprising about 750,000 square miles (1,900,000 km2) of ocean but only about 70 square miles (180 km2) of land mass. Each includes 15 to 18 islands and atolls. The country consists of a total of 29 atolls and five isolated islands.

Although Germany used forced labourers in most occupied countries, Poles and other Slavs were viewed as inferior by Nazi propaganda, thus, better suited for such duties. Between 1 and 2.5 million Polish citizens were transported to the Reich for forced labour, against their will. All Polish males were required to perform forced labour. While ethnic Poles were subject to selective persecution, all ethnic Jews were targeted by the Reich. In the winter of 1939–40, about 100,000 Jews were thus deported to Poland. They were initially gathered into massive urban ghettos, such as 380,000 held in the Warsaw Ghetto, where large numbers died under the harsh conditions therein, including 43,000 in the Warsaw Ghetto alone. Poles and ethnic Jews were imprisoned in nearly every camp of the extensive concentration camp system in German-occupied Poland and the Reich. In Auschwitz, which began operating on 14 June 1940, 1.1 million people died.

With the help of Charles Stearn, an expert on vacuum pumps, in 1878, Swan developed a method of processing that avoided the early bulb blackening. This received a British Patent in 1880.[dubious – discuss] On 18 December 1878, a lamp using a slender carbon rod was shown at a meeting of the Newcastle Chemical Society, and Swan gave a working demonstration at their meeting on 17 January 1879. It was also shown to 700 who attended a meeting of the Literary and Philosophical Society of Newcastle upon Tyne on 3 February 1879. These lamps used a carbon rod from an arc lamp rather than a slender filament. Thus they had low resistance and required very large conductors to supply the necessary current, so they were not commercially practical, although they did furnish a demonstration of the possibilities of incandescent lighting with relatively high vacuum, a carbon conductor, and platinum lead-in wires. Besides requiring too much current for a central station electric system to be practical, they had a very short lifetime. Swan turned his attention to producing a better carbon filament and the means of attaching its ends. He devised a method of treating cotton to produce 'parchmentised thread' and obtained British Patent 4933 in 1880. From this year he began installing light bulbs in homes and landmarks in England. His house was the first in the world to be lit by a lightbulb and also the first house in the world to be lit by hydroelectric power. In 1878 the home of Lord Armstrong at Cragside was also among the first houses to be lit by electricity. In the early 1880s he had started his company. In 1881, the Savoy Theatre in the City of Westminster, London was lit by Swan incandescent lightbulbs, which was the first theatre, and the first public building in the world, to be lit entirely by electricity.

Influences also came to her from the art world, most notably through the works of Mexican artist Frida Kahlo. The music video of the song "Bedtime Story" featured images inspired by the paintings of Kahlo and Remedios Varo. Madonna is also a collector of Tamara de Lempicka's Art Deco paintings and has included them in her music videos and tours. Her video for "Hollywood" (2003) was an homage to the work of photographer Guy Bourdin; Bourdin's son subsequently filed a lawsuit for unauthorised use of his father's work. Pop artist Andy Warhol's use of sadomasochistic imagery in his underground films were reflected in the music videos for "Erotica" and "Deeper and Deeper".

On Saturday, 24 June 1950, U.S. Secretary of State Dean Acheson informed President Truman that the North Koreans had invaded South Korea. Truman and Acheson discussed a U.S. invasion response and agreed that the United States was obligated to act, paralleling the North Korean invasion with Adolf Hitler's aggressions in the 1930s, with the conclusion being that the mistake of appeasement must not be repeated. Several U.S. industries were mobilized to supply materials, labor, capital, production facilities, and other services necessary to support the military objectives of the Korean War. However, President Truman later acknowledged that he believed fighting the invasion was essential to the American goal of the global containment of communism as outlined in the National Security Council Report 68 (NSC-68) (declassified in 1975):

Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage. Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams. Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes. Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 °C (40 °F) and deliver outlet temperatures of 45–60 °C (113–140 °F). The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems. As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.
