The arrangement of plates and dielectric has many variations depending on the desired ratings of the capacitor. For small values of capacitance (microfarads and less), ceramic disks use metallic coatings, with wire leads bonded to the coating. Larger values can be made by multiple stacks of plates and disks. Larger value capacitors usually use a metal foil or metal film layer deposited on the surface of a dielectric film to make the plates, and a dielectric film of impregnated paper or plastic – these are rolled up to save space. To reduce the series resistance and inductance for long plates, the plates and dielectric are staggered so that connection is made at the common edge of the rolled-up plates, not at the ends of the foil or metalized film strips that comprise the plates.

Question: Why are the plates and dielectrics often staggered in larger value capacitors?
Answer: To reduce the series resistance and inductance.

The current–voltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.

Question: What can cause a large change in current in LEDs?
Answer: a small change in voltage.

The total number of Greeks living outside Greece and Cyprus today is a contentious issue. Where Census figures are available, they show around 3 million Greeks outside Greece and Cyprus. Estimates provided by the SAE - World Council of Hellenes Abroad put the figure at around 7 million worldwide. According to George Prevelakis of Sorbonne University, the number is closer to just below 5 million. Integration, intermarriage, and loss of the Greek language influence the self-identification of the Omogeneia. Important centres of the New Greek Diaspora today are London, New York, Melbourne and Toronto. In 2010, the Hellenic Parliament introduced a law that enables Diaspora Greeks in Greece to vote in the elections of the Greek state. This law was later repealed in early 2014.

The Gospel of Luke begins its account of Mary's life with the Annunciation, when the angel Gabriel appeared to her and announced her divine selection to be the mother of Jesus. According to gospel accounts, Mary was present at the Crucifixion of Jesus and is depicted as a member of the early Christian community in Jerusalem. According to Apocryphal writings, at some time soon after her death, her incorrupt body was assumed directly into Heaven, to be reunited with her soul, and the apostles thereupon found the tomb empty; this is known in Christian teaching as the Assumption.

A zygote initially develops into a hollow sphere, called a blastula, which undergoes rearrangement and differentiation. In sponges, blastula larvae swim to a new location and develop into a new sponge. In most other groups, the blastula undergoes more complicated rearrangement. It first invaginates to form a gastrula with a digestive chamber, and two separate germ layers — an external ectoderm and an internal endoderm. In most cases, a mesoderm also develops between them. These germ layers then differentiate to form tissues and organs.

---

Question: What are the 2 germ layers formed by most blastula?
Answer: an external ectoderm and an internal endoderm.

The first use of asphalt/bitumen in the New World was by indigenous peoples. On the west coast, as early as the 13th century, the Tongva, Luiseño and Chumash peoples collected the naturally occurring asphalt/bitumen that seeped to the surface above underlying petroleum deposits. All three used the substance as an adhesive. It is found on many different artifacts of tools and ceremonial items. For example, it was used on rattles to adhere gourds or turtle shells to rattle handles. It was also used in decorations. Small round shell beads were often set in asphaltum to provide decorations. It was used as a sealant on baskets to make them watertight for carrying water. Asphaltum was used also to seal the planks on ocean-going canoes.

Studio producers Richard D. Zanuck and David Brown offered Spielberg the director's chair for Jaws, a thriller-horror film based on the Peter Benchley novel about an enormous killer shark. Spielberg has often referred to the gruelling shoot as his professional crucible. Despite the film's ultimate, enormous success, it was nearly shut down due to delays and budget over-runs. But Spielberg persevered and finished the film. It was an enormous hit, winning three Academy Awards (for editing, original score and sound) and grossing more than $470 million worldwide at the box office. It also set the domestic record for box office gross, leading to what the press described as "Jawsmania.":248 Jaws made Spielberg a household name and one of America's youngest multi-millionaires, allowing him a great deal of autonomy for his future projects.:250 It was nominated for Best Picture and featured Spielberg's first of three collaborations with actor Richard Dreyfuss.

Much media attention on the season had been focused on the three black singers, Fantasia Barrino, LaToya London, and Jennifer Hudson, dubbed the Three Divas. All three unexpectedly landed on the bottom three on the top seven result show, with Hudson controversially eliminated. Elton John, who was one of the mentors that season, called the results of the votes "incredibly racist". The prolonged stays of John Stevens and Jasmine Trias in the finals, despite negative comments from the judges, had aroused resentment, so much so that John Stevens reportedly received a death threat, which he dismissed as a joke 'blown out of proportion'.

The English term comics is used as a singular noun when it refers to the medium and a plural when referring to particular instances, such as individual strips or comic books. Though the term derives from the humorous (or comic) work that predominated in early American newspaper comic strips, it has become standard also for non-humorous works. It is common in English to refer to the comics of different cultures by the terms used in their original languages, such as manga for Japanese comics, or bandes dessinées for French-language comics. There is no consensus amongst theorists and historians on a definition of comics; some emphasize the combination of images and text, some sequentiality or other image relations, and others historical aspects such as mass reproduction or the use of recurring characters. The increasing cross-pollination of concepts from different comics cultures and eras has further made definition difficult.

Question: French comics are also known as what?
Answer: bandes dessinées.

Some polychaetes breed only once in their lives, while others breed almost continuously or through several breeding seasons. While most polychaetes remain of one sex all their lives, a significant percentage of species are full hermaphrodites or change sex during their lives. Most polychaetes whose reproduction has been studied lack permanent gonads, and it is uncertain how they produce ova and sperm. In a few species the rear of the body splits off and becomes a separate individual that lives just long enough to swim to a suitable environment, usually near the surface, and spawn.

In the 1970s, job losses due to industrial restructuring caused New York City to suffer from economic problems and rising crime rates. While a resurgence in the financial industry greatly improved the city's economic health in the 1980s, New York's crime rate continued to increase through that decade and into the beginning of the 1990s. By the mid 1990s, crime rates started to drop dramatically due to revised police strategies, improving economic opportunities, gentrification, and new residents, both American transplants and new immigrants from Asia and Latin America. Important new sectors, such as Silicon Alley, emerged in the city's economy. New York's population reached all-time highs in the 2000 Census and then again in the 2010 Census.

In the US, dietitians are registered (RD) or licensed (LD) with the Commission for Dietetic Registration and the American Dietetic Association, and are only able to use the title "dietitian," as described by the business and professions codes of each respective state, when they have met specific educational and experiential prerequisites and passed a national registration or licensure examination, respectively. In California, registered dietitians must abide by the "Business and Professions Code of Section 2585-2586.8". Anyone may call themselves a nutritionist, including unqualified dietitians, as this term is unregulated. Some states, such as the State of Florida, have begun to include the title "nutritionist" in state licensure requirements. Most governments provide guidance on nutrition, and some also impose mandatory disclosure/labeling requirements for processed food manufacturers and restaurants to assist consumers in complying with such guidance.

San Diego's first television station was KFMB, which began broadcasting on May 16, 1949. Since the Federal Communications Commission (FCC) licensed seven television stations in Los Angeles, two VHF channels were available for San Diego because of its relative proximity to the larger city. In 1952, however, the FCC began licensing UHF channels, making it possible for cities such as San Diego to acquire more stations. Stations based in Mexico (with ITU prefixes of XE and XH) also serve the San Diego market. Television stations today include XHTJB 3 (Once TV), XETV 6 (CW), KFMB 8 (CBS), KGTV 10 (ABC), XEWT 12 (Televisa Regional), KPBS 15 (PBS), KBNT-CD 17 (Univision), XHTIT-TDT 21 (Azteca 7), XHJK-TDT 27 (Azteca 13), XHAS 33 (Telemundo), K35DG-D 35 (UCSD-TV), KDTF-LD 51 (Telefutura), KNSD 39 (NBC), KZSD-LP 41 (Azteca America), KSEX-CD 42 (Infomercials), XHBJ-TDT 45 (Gala TV), XHDTV 49 (MNTV), KUSI 51 (Independent), XHUAA-TDT 57 (Canal de las Estrellas), and KSWB-TV 69 (Fox).

The discipline of plant ecology was pioneered in the late 19th century by botanists such as Eugenius Warming, who produced the hypothesis that plants form communities, and his mentor and successor Christen C. Raunkiær whose system for describing plant life forms is still in use today. The concept that the composition of plant communities such as temperate broadleaf forest changes by a process of ecological succession was developed by Henry Chandler Cowles, Arthur Tansley and Frederic Clements. Clements is credited with the idea of climax vegetation as the most complex vegetation that an environment can support and Tansley introduced the concept of ecosystems to biology. Building on the extensive earlier work of Alphonse de Candolle, Nikolai Vavilov (1887–1943) produced accounts of the biogeography, centres of origin, and evolutionary history of economic plants.

Raymond B. Bragg, the associate editor of The New Humanist, sought to consolidate the input of Leon Milton Birkhead, Charles Francis Potter, and several members of the Western Unitarian Conference. Bragg asked Roy Wood Sellars to draft a document based on this information which resulted in the publication of the Humanist Manifesto in 1933. Potter's book and the Manifesto became the cornerstones of modern humanism, the latter declaring a new religion by saying, "any religion that can hope to be a synthesising and dynamic force for today must be shaped for the needs of this age. To establish such a religion is a major necessity of the present." It then presented 15 theses of humanism as foundational principles for this new religion.

With Egypt and Macedonia weakened, the Seleucid Empire made increasingly aggressive and successful attempts to conquer the entire Greek world. Now not only Rome's allies against Philip, but even Philip himself, sought a Roman alliance against the Seleucids. The situation was made worse by the fact that Hannibal was now a chief military advisor to the Seleucid emperor, and the two were believed to be planning an outright conquest not just of Greece, but of Rome itself. The Seleucids were much stronger than the Macedonians had ever been, because they controlled much of the former Persian Empire, and by now had almost entirely reassembled Alexander the Great's former empire.

The announcement came two years after Dell Inc. returned to private ownership, claiming that it faced bleak prospects and would need several years out of the public eye to rebuild its business. It's thought that the company's value has roughly doubled since then. EMC was being pressured by Elliott Management, a hedge fund holding 2.2% of EMC's stock, to reorganize their unusual "Federation" structure, in which EMC's divisions were effectively being run as independent companies. Elliott argued this structure deeply undervalued EMC's core "EMC II" data storage business, and that increasing competition between EMC II and VMware products was confusing the market and hindering both companies. The Wall Street Journal estimated that in 2014 Dell had revenue of $27.3 billion from personal computers and $8.9bn from servers, while EMC had $16.5bn from EMC II, $1bn from RSA Security, $6bn from VMware, and $230 million from Pivotal Software. EMC owns around 80 percent of the stock of VMware. The proposed acquisition will maintain VMware as a separate company, held via a new tracking stock, while the other parts of EMC will be rolled into Dell. Once the acquisition closes Dell will again publish quarterly financial results, having ceased these on going private in 2013.

A commonly seen example is the double happiness symbol 囍, formed as a ligature of 喜喜 and referred to by its disyllabic name (simplified Chinese: 双喜; traditional Chinese: 雙喜; pinyin: shuāngxǐ). In handwriting, numbers are very frequently squeezed into one space or combined – common ligatures include 廿 niàn, "twenty", normally read as 二十 èrshí, 卅 sà, "thirty", normally read as 三十 sānshí, and 卌 xì "forty", normally read as 四十 "sìshí". In some cases counters are also merged into one character, such as 七十人 qīshí rén "seventy people". Another common abbreviation is 门 with a "T" written inside it, for 問題, 问题, wèntí ("question; problem"), where the "T" is from pinyin for the second syllable tí 题. Since polysyllabic characters are often non-standard, they are often excluded incharcter dictionaries.

The music of the indigenous peoples of Central Mexico and Central America was often pentatonic. Before the arrival of the Spaniards and other Europeans, music was inseparable from religious festivities and included a large variety of percussion and wind instruments such as drums, flutes, sea snail shells (used as a trumpet) and "rain" tubes. No remnants of pre-Columbian stringed instruments were found until archaeologists discovered a jar in Guatemala, attributed to the Maya of the Late Classic Era (600–900 CE), which depicts a stringed musical instrument which has since been reproduced. This instrument is one of the very few stringed instruments known in the Americas prior to the introduction of European musical instruments; when played it produces a sound virtually identical to a jaguar's growl.
